Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

In order to facilitate understanding of the design, in the drawings, the distance between two adjacent conducting rods 8 is drawn to be a macroscopic wide width, and in the actual application process, the distance between two adjacent conducting rods 8 is very small.

As shown in fig. 1 to 4, the digital display gear automatic adjusting device of the self-adaptive intelligent fan comprises a driving assembly and an adjusting assembly, wherein the driving assembly comprises a plurality of wires 1, a power supply 2 for providing energy, and a driving motor 3 for driving the industrial fan to rotate, the power supply 2 is connected with the driving motor 3 in series through the wires 1, the two ends of the outmost end of each wire 1 are respectively provided with a conductive head 4 for external connection, the adjusting assembly comprises a cylinder 5, a movable body 6 and a magnet 7, the cylinder 5 is horizontally and fixedly arranged and is provided with a movable hole in the horizontal direction, the movable body 6 is arranged in the movable hole in a sliding manner, a containing cavity is formed between the movable body 6 and the movable hole, gas is arranged in the containing cavity, the movable body 6 is made of an insulating material, the movable body 6 is provided with a plurality of conductive rods 8 at equal intervals horizontally, the resistance values of the conductive rods 8 are different, and the resistance value, the two conductive heads 4 are oppositely and fixedly arranged and are positioned on a moving path of the movable body 6, the end parts of two ends of each conductive rod 8 can be butted with the conductive heads 4 to form a passage after the movable body 6 moves, the magnet 7 is fixedly arranged and is positioned on the moving path of the interactive body, the conductive heads 4 are fixedly provided with the adsorption bodies 9 with magnetism, the magnet 7 can adsorb the adsorption body 9 closest to the magnet 7 to the position closest to the magnet, and the conductive rod 8 and the conductive heads 4 are necessarily butted at the position.

Initially, when the temperature is too low, the gas in the cavity is in a contracted state, and the pressure given to the movable body 6 by the external air is much greater than the adsorption force given to the adsorption body 9 by the magnet 7, the movable body 6 is in the state shown in fig. 3, at this time, there is no passage of the conductive rod 8 and the conductive head 4 in butt joint to form the driving component, so the driving motor 3 stops operating, the gas gradually expands with the rise of the external environment temperature, when the gas expands to a certain value, the attraction force given to the adsorption body 9 by the magnet 7 can overcome the pressure given to the movable body 6 by the air and the friction force between the movable body 6 and the cylinder 5, the magnet 7 can adsorb the conductive rod 8, so that the resistance value of the conductive rod 8 at the passage of the driving component is maximum, when the gas continuously expands, the gas pressure in the cavity gradually increases until the pressure given to the movable body 6 by the gas pressure is enough to overcome the adsorption force given to the adsorption body 9 by the magnet 7, the conductive rod 8 can be slowly separated from the conductive head 4, when they are completely separated, because of the tiny distance between the adjacent conductive rods 8, another conductive rod 8 adjacent to the former conductive rod can be butted with the conductive head 4 at a very short moment after matching with the adsorption of the magnet 7, but the resistance value of the conductive rod 8 is different from the former one, so that the power output by the final driving motor 3 is changed.

As to how the power is changed, we first assume that if the voltage across the power source 2 is U (in practice, the voltage here is the national standard power consumption, namely 220V), the current of the whole circuit is I, the resistance of the driving motor 3 is R1, and the resistance of the conducting rod 8 is R2, so as to neglect the resistance of the conducting wire 1 for the convenience of calculation, then the following formula of the series circuit is obtained according to the physics of the series circuit:

the total power generated by the whole circuit is UI U²/(R1+R2)，

Power P (drive) of the drive motor 3 is I² R1＝[U/(R1+R2)]²R1＝U² R1/(R1+R2)²，

Wherein, U is the definite value, R1 is also the definite value (the influence that the temperature brought is very little, can ignore), then the value of P (total) and P (drive) is decided by R2 completely, and because the conducting rod 8 resistance value that is closer to barrel 5 is littleer, show after ambient temperature grow, the atmospheric pressure grow in the appearance chamber, the resistance value R2 of conducting rod 8 with conducting head 4 butt joint can diminish, R2 is in the denominator position in the formula of P (total) and P (drive), so P (total) and P (drive) have all increased, the rotational speed of fan can improve after the power increase of driving motor 3, the radiating effect also can be higher.

On the contrary, when the temperature is reduced, the air pressure in the cavity becomes small, the resistance value R2 of the conductive rod 8 butted with the conductive head 4 becomes large, P (total) and P (drive) are both reduced, the heat dissipation effect is reduced, but the consumed energy is also correspondingly reduced.

According to the above discussion, it can be known that the present invention is based on the principle of expansion with heat and contraction with cold of gas, and the effect of expansion or contraction generated by the gas in the cavity due to the external environment temperature changes the internal air pressure to perform automatic gear switching, and the conductive rods 8 with different resistance values correspond to different gears.

Wherein, there is a very critical element in the design of the magnet 7 and the adsorber 9, because there is a space between two adjacent conducting rods 8, after the movable body 6 moves due to the change of the air pressure inside the cavity, if two conducting heads 4 are just between the spaces of two adjacent conducting rods 8, the driving assembly will be disconnected, resulting in a long-time "neutral" condition, so to deal with this problem, the key factors of the magnet 7 and the adsorber 9 will be reflected, and their attraction will automatically realize moving the nearest conducting rod 8 to the position where it is butted with the conducting head 4, of course, in order to realize this process, the magnetic force of the magnet 7 should be sufficiently large, and the contact surface between the movable body 6 and the cylinder 5 should be sufficiently smooth, after ensuring that the attraction force given to the adsorber 9 by the magnet 7 can overcome the friction force of the movable body 6 to the cylinder 5 and the air pressure of the gas in the cavity or the air pressure given to the cylinder 5 by the outside air, the magnet 7 can force the adsorption body 9 nearest to the magnet to be adsorbed to the position nearest to the magnet, namely, the movable body 6 is driven to move, and the conductive rod 8 is butted with the conductive head 4.

Of course, the magnet 7 and the absorber 9 can only avoid the problem of long-time neutral gear, but the existence of neutral gear is always found at the moment when the conductive head 4 is separated from the conductive rod 8, the design only avoids the time interval of neutral gear as much as possible through the structure, the specific time interval of neutral gear depends on the distance between two adjacent conductive rods 8, the neutral period is very little as long as the distance is designed to be small enough, and the transverse length of two end surfaces of the conductive rod 8 can be lengthened for reducing the neutral gear time, because the end surfaces of the conductive head 4 and the conductive rod 8 are in point contact, a passage can be formed as long as any point is contacted, so in the transverse movement process of the conductive rod 8 relative to the conductive head 4 because of the change of air pressure, the original conductive rod 8 can always form a passage until the edge of the previous conductive rod 8 is separated from the conductive head 4, and as long as the air pressure of the cavity is changed a little again, the edge of the adjacent conducting rod 8 is butted with the conducting head 4 to form another passage.

As shown in fig. 1, a gas port 10 communicating with the cavity is formed in the cylinder 5, and a piston is detachably disposed on the gas port 10.

The size of the port 10 is very small and it serves many purposes:

gas can be filled into the cavity;

in the debugging process, when the air pressure in the cavity is too large and the adsorption force of the magnet 7 is not selected to be a proper value, and the adsorption force is too large to cause that the air pressure is large enough to push the movable body 6, the air port 10 plays a role of releasing pressure, and the movable body 6 is prevented from being rushed out at the moment when the air pressure reaches a certain value;

the gas valve can also be used under the condition that the piston is opened, so long as the efficiency of the expansion or contraction of the gas in the cavity is ensured to be much higher than the efficiency of the discharge or suction from the gas port 10, the influence caused by the fact that the gas hole is always in an open state can be ignored, and when the gas port 10 is always opened, a certain pressure relief effect can be started to play a role in protection.

As shown in fig. 3, the end of the outer end of the conductive head 4 is an arc surface, an elastic hole is formed in the conductive head 4, an elastic member 11 is arranged in the elastic hole, and two ends of the elastic member 11 are respectively fixed on the bottom surface of the elastic hole of the conductive head 4 and the end surface of the wire 1.

Fix the wire 1 of tip, then set up conducting head 4 at this wire 1 tip through elastic component 11, when conducting rod 8 passes through, conducting head 4 is moved back after being extrudeed by conducting rod 8, but conducting head 4 has contacted with conducting rod 8 this moment, so form the route, conducting rod 8 passes through the back, conducting head 4 playback under the effect of elastic component 11, this design is in order to guarantee that conducting head 4 and conducting rod 8 carry out inseparable contact, this inseparable laminating effect is just accomplished by elastic component 11 again.

As shown in fig. 3, a ring of blocking disc 12 is fixedly arranged on the movable body 6, the blocking disc 12 is located between the cylinder 5 and the conducting rod 8, the blocking disc 12 is designed to prevent the movable body 6 from excessively contracting, so that part of the parts on the movable body 6 collide with the edge of the cylinder 5 to damage the parts, when the air pressure in the cavity is too small, the phenomenon is easily caused, but the blocking disc 12 is provided to avoid the situation.

The above design only provides the structure and principle, and it needs to be calculated and experimented to specifically select the magnetic performance of the magnet 7, the material of the contact surface between the cylinder 5 and the movable body 6, the raw material of the gas, and the distance between the conducting rods 8.

Therefore, before the automatic gear adjusting device is put into use, debugging is required according to different external environments, the spacing intervals between the conducting rods 8 are required to be consistent so as to ensure that the sizes of critical section sites of the temperature are also consistent, in the debugging process, if the number of the conducting rods 8 is too large, measurement and alignment are required to be carried out after the positions of the conducting rods 8 are adjusted every time, and the spacing between the conducting rods 8 is very small, so that the measurement and alignment process is very difficult, and the invention also provides the following structure for ensuring the consistency of the spacing intervals of the conducting rods in the debugging process:

as shown in fig. 1 to 4, the movable body is further provided with an interval adjusting part, the interval adjusting part comprises a support plate 13 fixedly arranged on the movable body 6, the movable body 6 is further provided with a slot 14 in a transverse penetrating manner, a plurality of support blocks 15 consistent with the conductive rod 8 are arranged in the slot 14 in a sliding manner, the interval size of each support block 15 is consistent, the support blocks 15 are made of insulating materials, the support blocks are transversely provided with through holes in a penetrating manner, the conductive rod 8 is fixedly arranged in the through holes, two ends of the conductive rod extend out of the through holes, the support blocks 15 are fixedly provided with lifting blocks 16, the top ends of the lifting blocks 16 are provided with lengthening blocks 17, the lengthening blocks 17 are provided with racks 18, the height sizes of the lifting blocks 16 are different, the virtual central planes of the two support blocks 15 at the outermost ends are taken as a reference plane, the lifting blocks 16 closer to the reference plane are higher in height, and the two lifting blocks 16 symmetrical relative to the reference plane are in the same plane, the lifting blocks 16 on the same side of the reference surface are not all in the same plane, a plurality of rotating holes are arranged on the support plate 13 in a penetrating manner, a plurality of rotating shafts 19 are arranged in the rotating holes in a rotating manner, one end of each rotating shaft 19 is provided with a linkage gear 20, the specification parameters of each linkage gear 20 are the same and are positioned on the same plane, the other end of each rotating shaft 19 is provided with an expansion gear 21, the linkage gears 20 and the expansion gears 21 are respectively positioned on two sides of the support plate 13, the lengths of part of the rotating shafts 19 are different so that part of the expansion gears 21 are positioned on different planes, the expansion gears 21 are meshed with racks 18 at corresponding positions, the specification parameters of the expansion gears 21 positioned on the same plane are consistent, the radius of the expansion gear 21 far away from the reference surface is larger, and if the radius of the expansion gear 21 closest to the reference surface in the same side of the reference surface is r, the radius of the expansion gear 21 closest to the reference surface is (2n-1) r or nr, the support plate 13 is rotatably provided with a tightening rod and an adjusting rod, the tightening rod is provided with a tightening gear 22, the adjusting rod is provided with an adjusting gear 23, the outer end of the adjusting gear 23 extends to be provided with an adjusting handle 24, the tightening gear 22 and the adjusting gear 23 are provided with a toothed belt 25 in a hanging manner, the toothed belt 25 is provided with inner teeth and outer teeth with the same parameters, the inner teeth are internally engaged with the linkage gear 20 on one side of the datum plane, the outer teeth are externally engaged with the linkage gear 20 on the other side of the datum plane, and the linkage gear 20 which is externally engaged is closer to the tightening gear 22 and the adjusting gear 23 than the linkage size of the outer engagement.

Where the drawings presented herein employ an even number of conductor bars 8, the following discussion in conjunction with the drawings is also based on the even number of conductor bars 8.

The staggered design of the expansion and contraction gear 21, the lifting block 16 and the lengthening block 17 is mainly because the size of the expansion and contraction gear 21 is greatly different, particularly, the radius difference between the largest expansion and contraction gear 21 and the smallest expansion and contraction gear 21 is large, the difference is more obvious after the surfaces are converted into the square difference, and if the difference is not staggered, the phenomenon of die penetration is easy to generate, and the situation that the assembly cannot be carried out due to interference is generated in the manufacturing process.

The above symmetrical form of the present invention is mainly aimed at saving space, and actually it can be implemented if it is a single-sided form, but it is not difficult to see from the formula (2n-1), and if it is a single-sided form, the size of the largest expansion and contraction gear 21 will be very large, and it is easy to generate interference due to space problem during the placement of the components.

For the component, a toothed belt 25 with internal teeth and external teeth is adopted, and the reference plane for symmetry is taken as a central plane, the linkage gears 20 on one side are linked by internal teeth, the linkage gears 20 on the other side are linked by external teeth, by adopting the design, when the toothed belt 25 rotates in the same direction, the linkage gears 20 on one side of the reference plane synchronously rotate forward at the same speed, the linkage gears 20 on the other side of the reference plane synchronously rotate backward at the same speed, after the rotating shaft 19 is output to the rack 18 through the expanding and contracting gear 21, the conducting rods 8 on two sides of the reference plane finally approach or separate from each other in a symmetrical mode, and in order to ensure that the distance between the adjacent conducting rods 8 is consistent in the moving process, the size of the expanding and contracting gear 21 needs to be reasonably designed because all the linkage gears 20 rotate under the driving of the toothed belt 25, therefore, the rotation speeds of all the rotating shafts 19 are the same, that is, the angular speeds of the expansion and contraction gears 21 are the same, according to the formula V ═ WR between the angular speed and the linear speed, in the case of the same angular speed, the linear speed of the contact point between the expansion and contraction gear 21 and the rack 18 is completely determined by the radius R of the expansion and contraction gear 21, and the radius of the expansion and contraction gear 21 which is n-th from the central reference plane is (2n-1) R, and the substituted data can indicate that the radius of the 1 st expansion and contraction gear 21 which is close to the reference plane is R, the 2 nd is 3R, the 3 rd is 5R, the 4 th is 7R, and so on, so that the dimensional design scheme is adopted, a coordinate system can be introduced to detail:

as shown in fig. 6, before the adjustment, it is assumed that the coordinate position of the reference plane is 0, the coordinate positions of the two conductive bars 8 closest to the reference plane are a and-a, the coordinate positions of the two conductive bars 8 closest to 2 of the reference plane are 3a and-3 a, and the coordinate positions of the two conductive bars 8 closest to 3 of the reference plane are 5a and-5 a, and it is easy to see that the distance between the two adjacent conductive bars 8 is 2 a.

After the adjustment, since the radius of the expanding and contracting gear 21 closest to the reference surface is r, the 2 nd is 3r, and the 3 rd is 5r, when the two conductor bars 8 closest to the reference surface move by a distance of b, the two conductor bars 8 closest to the 2 nd of the reference surface move by 3b, the two conductor bars 8 closest to the 3 rd of the reference surface move by 5b, and the distances between the adjacent conductor bars are always the same value, i.e., 2(a + b), although they move by different distances in a coordinate view, that is, the distances between the adjacent conductor bars 8 are always the same regardless of how the adjustment is made.

For easy understanding, we can also substitute data, as shown in fig. 7, before the adjustment, the distance between two adjacent conducting rods 8 is 2cm, but when the conducting rod 8 closest to the reference surface moves by 1cm, the conducting rod 8 closest to the reference surface at 2 nd moves by 3cm, and the conducting rod 8 closest to the reference surface at 3 rd moves by 5cm, and they are respectively located at new coordinate points, but the distances are all changed from 2cm to 4cm, which is why the radius of the expanding and contracting gear 21 at the nth closest to the central reference surface is (2n-1) r.

The above discussion and the drawings are based on the condition that the number of the conducting rods 8 is even, of course, the number of the conducting rods 8 may be odd, at this time, the conducting rod 8 at the center is just on the virtual center reference plane in the discussion, and the conducting rod 8 may be stationary, and then on the premise of odd number of the conducting rods 8, the distance between the two conducting rods 8 which are closest to the reference plane is not the distance between the two conducting rods 8, but the distance between the two conducting rods and the middle conducting rod 8, so the radius formula of the expansion gear 21 should be nr at this time, and other implementation principles are not changed.

As shown in FIG. 3, the bottom surface of the slot 14 is provided with a limiting groove 26, the bottom surface of the supporting block 15 is provided with a limiting block 27, and the limiting block 27 is slidably disposed in the limiting groove 26, which is designed to prevent the supporting block 15 from laterally separating from the slot.

As shown in fig. 3, a stopper 28 is disposed in the middle of the slot 14, and the existence of the stopper 28 can effectively prevent the two expansion and contraction gears 21 closest to the reference surface from colliding due to excessive internal memory during the debugging process of synchronous internal contraction.

After the adjustment is completed, the whole fixation can be completed only by fixedly locking any one of the linkage gear 20 or the expansion gear 21 or any one of the toothed belt 25, the tightening gear 22, the adjusting gear 23 and the adjusting handle 24, because the mechanical angle analysis shows that only one kinematic pair of the whole structure is needed, and the whole structure can be locked only by locking one part.

In order to improve the action effect of the magnet and the adsorber, the adsorber can be arranged on both sides of the conducting rod, and the positioning effect is achieved by adsorbing the adsorber at corresponding pair positions by the magnets respectively, however, since the distance between the conducting rods can be adjusted, after the distance between the conducting rods is adjusted, the positions of the magnets are also adjusted correspondingly, and for this, the applicant also proposes the following technical scheme:
