Description
Technical Field
The utility model relates to an automobile parts field. Particularly, the utility model relates to a mechanical type electric horn and contact component thereof.
Background
The horn is a component that is commonly installed in automobiles and can be used to sound when needed by the driver to alert pedestrians or vehicles to ensure traffic safety. The automobile electric horn comprises a mechanical electric horn, and referring to fig. 1, the mechanical electric horn mainly comprises a static iron core 1, a coil 2, a contact component 3, a movable iron core 4 and a diaphragm 5. During operation, when the horn switch is turned on, current flows through the coil 2 via the contact member 3, and the energized coil 2 generates a magnetic field that attracts the plunger 4 downward, thereby moving the diaphragm 5. In turn, the downward movement of the plunger 4 causes the contact member 3 to open, the current to be interrupted, the coil 2 to lose its magnetic force so that the plunger 4 and the membrane 5 return to their original positions under the elastic action of the membrane 5 itself and the contact member 3, so that the contact member 3 is again closed, and accordingly current flows through the coil again through the contact member 3. The above-mentioned steps are repeated in this way, so that the vibration of the diaphragm 5 is ringing.
However, when the plunger 4 moves downward, the electromagnetic attraction forces F in opposite directionsMagnetic fieldAnd the force F received by the plunger 4 at the contact member 3Touch and touchTogether, there is a tendency for the plunger 4 to rotate (in the plane of fig. 1) substantially counter-clockwise when in contact with the contact member 3. Thereby, the diaphragm 5 is deformed like a fold around the connecting position with the plunger 4.

It is to be understood that the shape of the second contact support 323 is not limited to that shown in fig. 3, and the second contact support 323 may not be a closed surrounding structure but may have a break. The second contact support 323 can be of any material (e.g., metal conductor) and shape as desired to accomplish the objects of the present invention. If necessary, the second contact support 323 may be provided with a member advantageous for achieving the object of the present invention, for example, it may be covered with a buffer material or coated with a lubricant.
In one embodiment, the second contact 322 and the second contact support 323 are integrally formed at the first end 324 of the second contact sub-member 320, as shown in fig. 3. In another embodiment, the second contact 322 and the second contact support 323 may be connected in other ways to achieve the effect of controlling the contact and separation of the second contact 322 with the first contact 312 by the second contact support 323.
In one embodiment, the second end 326 of the second contact sub-member 320 and the second end 316 of the first contact sub-member 310 are connected to form an overall body. That is, the first and second ends 314 and 316 of the first contact sub-member 310 and the second end 326 of the second contact sub-member 320 are fixed, and the second end 324 thereof, at which the second contact 322 and the second contact support 323 are provided, can move within a certain range and in a certain direction.

According to a second aspect of the present invention, a mechanical electric horn 400 is provided, and fig. 4, 5 and 6 respectively schematically show a sectional view, a perspective view and a three-dimensional sectional view of the mechanical electric horn 400 according to an embodiment of the present invention.
The mechanical electrical horn 400 may include a first core 410, a diaphragm 420, a coil 430, a second core 440, and a contact member 300 (which is marked with a dashed box in fig. 4) as shown in fig. 3 and described above. Wherein one end of the coil 430 is wound around the first core 410, and a first end of the second core 440 is wound by the other end of the coil 430, and a second end of the second core 440 is connected to the diaphragm 420.
Wherein the contact member 300 includes a first contact sub-member 310 and a second contact sub-member 320. A first contact sub-member (which may also be referred to as a stationary contact sub-member) 310, on which a first contact (which may also be referred to as a stationary contact) 312 is provided, may be relatively fixedly mounted in the mechanical electric horn according to the present invention. In one embodiment, the first contact sub-member 310 may be elongated as shown in fig. 3, which may be fixed at a first end 314 and a second end 316, with the first contact disposed at the middle portion. It will be readily appreciated that the shape of the first contact sub-member 310 is not limited to the embodiment shown in fig. 3, but may take any configuration capable of providing functionality to implement the first contact 312 of the present invention.
As shown in fig. 4, the second contact holder 323 may be disposed to surround the second core 440 and move up and down by the second core 440. In one embodiment, the first end of the second core 440 has a smaller diameter than the second end, the first end of the second core 440 having the smaller diameter passes through the second contact support 323 and is surrounded by one end of the coil 430, and the outer edge (in the example of fig. 4) of the second end of the second core 440 protruding compared to the first end acts downward on the second contact support 323.
The contact member 300 may also include a second contact sub-member (also may be referred to as a movable contact sub-member) 320, which may include a second contact (also may be referred to as a movable contact) 322 and a second contact holder (also may be referred to as a movable contact holder) 324. The second contact point support 323 is provided to have a hollow surrounding structure, and its up and down movement may cause contact and separation of the first contact point and the second contact point. In one embodiment, as shown in fig. 3, the first contact 312 is disposed above the second contact 322, and in the initial state (first state), the first contact 312 remains in contact with the second contact 322. In one embodiment, the second contact support 323 is configured with a circular ring-shaped sheet.
It is to be understood that the shape of the second contact support 323 is not limited to that shown in fig. 3, and the second contact support 323 may not be a closed surrounding structure but may have a break. The second contact support 323 can be of any material (e.g., metal conductor) and shape as desired to accomplish the objects of the present invention. If necessary, the second contact support 323 may be provided with a member advantageous for achieving the object of the present invention, for example, it may be covered with a buffer material or coated with a lubricant.
Since the above-mentioned outer edge of the second core 440 (in the example of fig. 4) acts downward on the second contact support 323, when the switch of the horn is turned on, a current flows through the coil 430 via the contact member 300, and the energized coil 430 generates a magnetic field, attracting the plunger 440 downward, thereby moving the diaphragm 420. In turn, the downward movement of the plunger 440 causes the contact member 300 to open, the current to be interrupted, the coil 430 loses magnetic force so that the plunger 440 and the diaphragm 420 return to their original positions under the elastic action of the diaphragm 420 itself and the contact member 300, so that the first contact (stationary contact) 312 and the second contact (movable contact) 322 (not shown in fig. 4) on the contact member 300 are again made, and accordingly, current flows through the coil through the contact member 300 again. The above-mentioned steps are repeated in this way, so that the vibration of the diaphragm 420 is ringing.
In the case of the second contact support 323 of a hollow surrounding structure, since the interaction position between the second core 440 and the second contact support 323 is a ring structure, the force of the second core 440 against the second contact support 323 (and thus the second core 440 against the diaphragm 420) is uniformly distributed over one circumferential surface (as shown in the dashed circle in fig. 6). Therefore, the moment action on the second core 440 is more balanced, the torsional stress around the connection position of the diaphragm 420 and the second core 440 can be reduced or even eliminated, and the risk of the diaphragm 420 breaking at this position is reduced, thereby improving the durability of the diaphragm 420 and accordingly the service life of the horn.
In one embodiment, the second contact 322 and the second contact support 323 are integrally formed at the first end 324 of the second contact sub-member 320, as shown in fig. 3. In another embodiment, the second contact 322 and the second contact support 323 may be connected in other ways to achieve the effect of controlling the contact and separation of the second contact 322 with the first contact 312 by the second contact support 323.
In one embodiment, the second end 326 of the second contact sub-member 320 and the second end 316 of the first contact sub-member 310 are connected to form an overall body. That is, the first and second ends 314 and 316 of the first contact sub-member 310 and the second end 326 of the second contact sub-member 320 are fixed, and the second end 324 thereof, at which the second contact 322 and the second contact support 323 are provided, can move within a certain range and in a certain direction. In some embodiments, the connection may be achieved by one or more of riveting, welding, bolting, keying, pinning.
In one embodiment, the junction of the second contact sub-member 320 and the first contact sub-member 310 is insulated by an insulating material. The insulating material may be formed into any desired shape to electrically isolate the first contact sub-member 310 from the second contact sub-member 320 to achieve no current path between the first contact sub-member 310 and the second contact sub-member 320 when the first contact 312 is not in contact with the second contact 322.
In one embodiment, the first core 410, the coil 430, the second end 326 of the second contact sub-member 320, and the first contact sub-member 310 are fixedly connected. In one embodiment, the parts may be fixedly connected together and mounted in a mechanical electric horn according to an embodiment of the present invention. In an embodiment, the second core 440 is not connected to the second contact point support 323, but the second contact point support 323 moves upward together with the second contact point 322 during the upward movement of the second core 440 by using the elasticity of the second contact point member 320 and/or the diaphragm 420 itself until the second contact point 322 contacts the first contact point 312 to allow the flow of current. In another embodiment, the second core 440 is electrically isolated from the second contact support 323 by an insulating material 450 (see fig. 4). In one embodiment, the flange portion of the second core 440 is bonded to the insulating material 450, thereby providing electrical insulation when the second core 440 is in contact with the second contact support 323.
