In this embodiment, each locking hole 102 is disposed at a side portion of the lower rail 101, and is substantially arranged from one end of the lower rail 101 to the other end thereof, and at this time, the locking tooth plate 204 in the locking assembly is also horizontally arranged corresponding to the locking hole 102 disposed at the side portion, that is, slides along the width direction of the lower sliding rail 101, so that the locking teeth thereon can be inserted into the locking holes 102 at corresponding positions to form a plug-in fit, or can be pulled out from the locking holes 102. However, besides locating the locking hole 102 at the side of the lower rail 101, it is of course possible to locate the locking hole 102 at the bottom or top of the lower rail 101, but corresponding to the different positions of the locking hole 102, the locking assembly in the upper rail 201 also needs to be adjusted accordingly in terms of structural arrangement to enable proper locking or unlocking.
In order to improve the appearance quality of the lower rail assembly 1 and to protect the components therein, the present embodiment is also provided with soft decoration strips 103 arranged side by side on the top of the lower rail 101, and the upper rail 201 of the upper rail assembly 2 slides between the two soft decoration strips 103. In addition, end trim covers 105 arranged corresponding to the ends of the soft trim strips 103 and an end cover 104 closing the ends of the lower rail 101 are respectively arranged at the two ends of the lower rail 101, wherein the end cover 104 and the end trim cover 105 can both be made of plastic and can be fixed at the ends of the lower rail 101 in a clamping or screwing manner.
In order to mount and fix the lower rail assembly 1, the lower rail 101 of this embodiment is also provided with a connecting member 106 connected to the load-bearing base of the loading rail mechanism, and a positioning member 107 capable of positioning the connection of the connecting member 106. The above-mentioned load-bearing base is also generally referred to as a vehicle body, and when the seat of the present embodiment is used in other applications, it is understood that the load-bearing base is correspondingly other components for mounting the seat. In addition, as an exemplary structure, the connecting member 106 may be a bolt with a gasket, the positioning member 107 may be a positioning pin, and the connecting member 106 and the positioning member 107 may be respectively provided in a plurality as needed.
In this embodiment, the cross-sectional structure of the lower rail 101 is as shown in fig. 5, the lower rail 101 with the cross-section can be generally formed by an extrusion process, and in terms of specific structural design, first, a clamping groove 101a and a clamping claw 101b are symmetrically arranged on two opposite sides of the top of the lower rail 101, the clamping groove 101a and the clamping claw 101b are installation structures of the soft decoration strip 103, and the soft decoration strip 103 is directly clamped on the lower rail 101 through the clamping groove 101a and the clamping claw 101 b.
Also provided at the lower portion in the lower rail 101 are engagement inclined surfaces 101c symmetrically arranged on both sides, which are engaged with bearing assemblies 2013 described below, in particular. A limiting groove 101d is formed below each matching inclined surface 101c, the limiting grooves 101d on both sides are symmetrically and oppositely arranged, and the limiting grooves 101d on both sides together can enclose a space for placing the gasket in the connecting piece 106. At this time, the spacers in the connecting member 106 are respectively retained by the retaining grooves 101d on both sides, so that the connecting member 106 can be prevented from falling.
In addition to the lower limiting groove 101d, a first reverse buckle 101e, a second reverse buckle 101f, a third reverse buckle 101g and a fourth reverse buckle 101h are further disposed on the two opposite side walls in the lower rail 1, each reverse buckle on each side constitutes a reinforcing structure for improving the peeling strength between the upper rail and the lower rail, and corresponding to each reverse buckle, the upper rail 201 is also provided with buckle teeth respectively embedded in the corresponding reverse buckles. At this time, the engagement state of the teeth on the upper rail 201 and the reverse hooks on the lower rail 101 is as shown in fig. 9 described below. Furthermore, instead of the back-off and tooth structure shown in fig. 5 and 9, other similar structures may be adopted to increase the peel strength between the upper rail 201 and the lower rail 101.
In the present embodiment, generally opposite to the above-mentioned engaging inclined surface 101c, the upper portion of the upper rail 201 is also provided with a contact inclined surface 101i which is also symmetrically arranged on both sides, and the contact inclined surface 101i is used for engaging with the rolling body 20122 in the backlash eliminating assembly 2012 described below.
Fig. 6 to 8 show an exemplary structure of the upper rail assembly 2 of the present embodiment, wherein the upper rail 201 is also a long bar, but the length thereof is much shorter than that of the lower rail 101, the upper rail 201 is preferably an aluminum rail as described above, i.e., made of aluminum alloy, and it can be generally formed by an extrusion process, and further machined for final shaping after the extrusion process.
The cross-section of most of the upper rail 201 of this embodiment is shown in fig. 9, but the cross-section differs in the location where the anti-backlash assembly 2012, the bearing assembly 2013 and the locking assembly are disposed. As can be seen from fig. 9, as described above, the upper rail 201 is inserted into each reverse buckle in the lower rail 101 via the buckle teeth formed on both sides thereof, so that the upper rail 201 is advantageously prevented from being peeled off from the lower rail 101 while achieving sliding guidance therebetween.
Specifically, two stripping mechanisms 202 shown in fig. 10 are fixedly connected to the upper rail 201, the two stripping mechanisms are respectively disposed at two ends of the upper rail 201, each stripping mechanism 202 is fixedly connected to the upper rail 201 through a rivet 203, and a welding nut for connecting a seat is fixedly disposed in each stripping mechanism 202. In particular, the release mechanism 202 may be implemented by referring directly to the related components of the existing slide track structure of the car seat.
The present embodiment is directed to the locking assembly of the sliding rail locking mechanism, which is designed to have an operating end rotatably disposed in the upper rail 201, a locking end slidably disposed in the upper rail 201 corresponding to the locking hole 102, and a first elastic member 209 disposed at the upper rail 201 and the operating end. At this time, the locking end is also slidable by the urging of the first elastic member 209 to engage with at least one of the locking holes 102 to lock the upper rail 201 and the lower rail 101, and the locking end is also slidable in the opposite direction to release the locking by receiving an external operating force through the operating end.
In detail, fig. 11 to 13 show an exemplary structure of the locking assembly of the present embodiment, and the exemplary structure is specifically configured to match with the locking hole 102 at the side of the lower rail 101. Referring to fig. 11 and 12, the locking end of the present embodiment includes a locking toothed plate 204 provided with locking teeth, the manipulating end includes an unlocking rotating rod 206 rotatably disposed in the upper rail 201, and an unlocking pushing rod 207 fixedly connected to the unlocking rotating rod 206 and located on one side of the unlocking rotating rod 206, and the first elastic member 209 abuts against the unlocking pushing rod 207.
The locking teeth are specifically configured as a plurality at one end of the locking tooth plate 204, and as a preferred embodiment, the width of one of the locking teeth may be configured to match the width of the locking hole, so as to form anti-backlash teeth that can respectively contact with two side walls in the width direction of the locking hole, and meanwhile, the widths of the other locking teeth may be uniformly configured to be smaller than the anti-backlash teeth. In this way, by providing the backlash elimination teeth, the clearance in the X direction, that is, in the longitudinal direction of the lower rail 101 can be eliminated well during locking, and the stability of the locked upper rail 201 and the seat connected to the upper rail 201 can be improved.
In each locking tooth, the backlash eliminating tooth is generally a main tooth, and it may be one of the locking teeth located in the middle, or it may be a locking tooth at another position, and it may be selected according to actual requirements in specific design.
In addition, the unlocking rotating rod 206 and the unlocking pushing rod 207 of the present embodiment are specifically fixedly connected through an unlocking rotating bracket 208, and the unlocking rotating bracket 208 is located at the back of the locking toothed plate 204 and is respectively connected with the end portions of the unlocking rotating rod 206 and the unlocking pushing rod 207. The locking toothed plate 204 is further provided with a first elongated hole parallel to the locking direction of the locking end and a second elongated hole orthogonal to the first elongated hole, and the unlocking rotating rod 206 and the unlocking pushing rod 207 are respectively inserted into the first elongated hole and the second elongated hole as shown in fig. 11.
By making the unlocking rotating rod 206 be located in the first elongated hole and the unlocking pushing rod 207 be located in the second elongated hole, the direction of the two elongated holes is set, so that the external force can be received at the manipulation end, and the unlocking rotating rod 206 is rotated, and specifically, when counterclockwise rotation is performed with reference to fig. 11, the unlocking pushing rod 207 can be driven to synchronously rotate counterclockwise by the unlocking rotating rod 206 through the transmission of the unlocking rotating bracket 208. And then, the first strip hole and the second strip hole are respectively used for providing space for the movement of the unlocking rotating rod 206 and the unlocking pushing rod 207 relative to the locking toothed plate 204, so that the locking toothed plate 204 can be moved in a sliding manner, and the unlocking operation can be performed.
In order to reduce friction and eliminate noise, in this embodiment, a rotating rod sleeve 2011 is also sleeved outside the unlocking rotating rod 206, the rotating rod sleeve 2011 may be made of plastic, and the top of the rotating rod sleeve 2011 is still provided with two wall plates arranged side by side as shown in fig. 11 or fig. 12, and the rotating rod sleeve 2011 is clamped on the upper rail 201 as shown in fig. 6 and fig. 7 by the wall plates on both sides, so as to prevent the rotating rod sleeve 2011 from rotating along with the unlocking rotating rod 206.
In this embodiment, through the arrangement of the first elongated hole and the second elongated hole which are just orthogonal, when the unlocking rotating rod 206 rotates, the locking toothed plate 204 can slide to form an unlocking stroke, and certainly, in the unlocking process, the first elastic member 209 is in an energy storage state. Besides unlocking, when the external force for unlocking is removed at the operating end, under the action of the energy released by the first elastic element 209, the locking toothed plate 204 can also be translationally and slidably reset by utilizing the constraint of the two elongated holes, and then is inserted into the corresponding locking hole 102 to restore locking.
As a preferred embodiment, the first elastic member 209 of the present embodiment is a torsion spring sleeved on the unlocking rotating rod 206, and two ends of the torsion spring respectively abut against the unlocking pushing rod 207 and the upper rail 201. In addition, this embodiment has also been linked firmly the unblock handle 205 at the unblock dwang 206 other end, and meanwhile, also sets up the floodgate line connecting hole on unblock handle 205 to make the manipulation end for exert by the floodgate line external force and drive, the other end of floodgate line can adopt manual pulling structure or electronic pulling structure, in order to exert operating force.
However, in addition to providing the brake cable connection hole, the brake cable connection hole may not be provided on the unlocking handle 205 in this embodiment, so that the unlocking handle 205 can be pushed by other rigid manipulating members to unlock.
Through the wear-out of unblock dwang 206 in first rectangular downthehole to and the wear-out of unblock catch bar 207 in the rectangular downthehole of second establishes, this embodiment can realize promptly by external force drive or when being driven by first elastic component 209, the translation of locking pinion rack 204 slides. However, if only the unlocking rotating rod 206 and the unlocking pushing rod 207 are provided, the problem that the locking toothed plate 204 is easy to incline due to single-side suspension inevitably exists, and the motion stability is affected. At this time, as a further improvement, a third elongated hole parallel to the first elongated hole may be disposed on the locking tooth plate 204, and an unlocking support rod 2010 penetrating the third elongated hole is further disposed in the locking assembly, and the unlocking support rod 2010 is fixed on the upper rail 201.
The third elongated hole and the unlocking support rod 2010 are also shown in fig. 11 and 12, and in specific implementation, the unlocking support rod 2010 may be made of a plastic material or a metal composite material, so as to reduce friction and noise. Meanwhile, one end of the unlocking support rod 2010 can be clamped on the upper rail 201 as shown in fig. 13, and a circular baffle plate arranged on one side of the locking toothed plate 204 can be arranged at the other end of the unlocking support rod 2010 so as to support the locking toothed plate 204.
It should be noted that in the present embodiment, although the unlocking rotation rod 206 is located at one end of the locking toothed plate 204 in fig. 11 and 12, the unlocking push rod 207 is located at the middle of the locking toothed plate 204. However, as shown in fig. 14, in the specific implementation, it is of course possible that the unlocking rotation rod 206 is displaced to the middle of the locking toothed plate 204, and the unlocking push rod 207 is located at the end of the locking toothed plate 204. Also, since the unlocking rotation rod 206 itself can support the locking tooth plate 204 at this time, the unlocking support rod 2010 may be omitted as shown in fig. 12 when the unlocking rotation rod 206 is located at the middle portion. However, although the unlocking support lever 2010 may be omitted, it is still possible to provide the unlocking support lever 2010 on the other side of the unlocking rotation lever 206 with respect to the unlocking push lever 207 when the unlocking rotation lever 206 is located at the middle.
As shown in fig. 15, the gap eliminating assembly 12 of the present embodiment is a pair of gap eliminating assemblies 12, each gap eliminating assembly 12 is arranged on the upper rail 201 in a lever-like manner, and includes a gap eliminating bracket 20121, a rolling body 20122 at one end of the gap eliminating bracket 20121 and in rolling contact with the contact inclined surface 101i on the upper portion of the lower rail 101, and a second elastic member 20123 at the other end and in contact with the upper rail 201.
In this embodiment, the rolling elements 20122 are in rolling contact with the contact inclined surfaces 101i on the upper portion of the lower rail 101 in a one-to-one correspondence manner through a pair of anti-backlash inclined surfaces arranged oppositely thereon, and as shown in fig. 16, the pair of anti-backlash inclined surfaces on the rolling elements 20122 are arranged in a shape of "eight", and the contact inclined surfaces 101i on the two sides of the lower rail 101 are also arranged in a shape of "eight". At this time, the gap between the Y-direction and the Z-direction, that is, the gap between the lower rail 101 in the width direction and the height direction can be eliminated by the rolling contact between the gap eliminating inclined surface and the contact inclined surface 101 i.
In the arrangement of the anti-backlash assembly 2012, it is generally sufficient to rotate the anti-backlash bracket 20121 on the upper rail 201 through the rotating shaft 2014.
