[0029] With the popularity of MPV market, slide rails are widely used in market vehicle applications. At the same time, from the perspective of experience, drivers and passengers are concerned about the vehicle space. However, the existing slide rails are arranged with bolt holes, stop points, etc. in the middle, which limits the travel of the slide rails and affects the driving experience of passengers.

[0030] This embodiment provides a seat slide rail, which arranges the lower slide rail fixing point 11 on the outside of the slide groove 12 to avoid the first upper slide rail assembly 20 and the second upper slide rail assembly 30 being restricted in movement by the lower slide rail fixing point 11 when moving in the slide groove 12.

[0031] Specifically:

[0032] Reference Figure 1-3 As shown, the seat slide rail includes two groups of spaced-apart lower rails 10, a first upper rail assembly 20 and a second upper rail assembly 30; a slide groove 12 is provided in the lower rail 10, and the first upper rail assembly 20 and the second upper rail assembly 30 can slide in the slide groove 12; a lower rail fixing point 11 is provided on the lower rail 10, and the lower rail fixing point 11 is located on the outside of the slide groove 12.

[0033] In a possible implementation, the lower slide rail fixing points 11 are symmetrically arranged on both sides of the lower slide rail 10 . This has the advantage that the lower slide rail 10 can be fixed more stably on the vehicle body.

[0034] In addition, considering that different car models have different corresponding fixed positions on the car body, in one possible implementation method, the lower slide rail fixing point 11 is detachably connected to the outer side of the lower slide rail 10, so that the fixed position between the lower slide rail fixing point 11 and the lower slide rail 10 can be adjusted according to actual needs.

[0035] In this embodiment, the lower slide rail fixing point 11 is fixed to the vehicle body by bolts.

[0036] In this embodiment, the lower slide rail fixing point 11 is not provided in the slide groove 12, that is, the inner side of the slide groove 12 is slidably connected to the first upper slide rail assembly 20 and the second upper slide rail assembly 30, which can make the first upper slide rail assembly 20 and the second upper slide rail assembly 30 slide in the slide groove 12 without being disturbed by the bolt hole, the blocking point, etc., which affects the sliding travel of the first upper slide rail assembly 20 and the second upper slide rail assembly 30.

[0037] In one possible implementation, the first upper slide rail assembly 20 includes two first mounting blocks 21, and the two first mounting blocks 21 are respectively slidably connected to the two sets of lower slide rails 10; the second upper slide rail assembly 30 includes two second mounting blocks 31, and the two second mounting blocks 31 are respectively slidably connected to the two sets of lower slide rails 10. The advantage of this design is that the first upper slide rail assembly 20 and the second upper slide rail assembly 30 can slide on double rails with higher stability.

[0038] In one possible implementation, the seat slide also includes a screw assembly 40, which includes a screw 41, a support seat 42, a first sliding seat 43 and a second sliding seat 44; a screw 41 is connected between the two support seats 42, and the first sliding seat 43 and the second sliding seat 44 are respectively mounted on the screw 41 and slide between the two support seats 42.

[0039] The first upper slide rail assembly 20 and the second upper slide rail assembly 30 are respectively fixedly connected to the support seat 42 , and the movement of the first upper slide rail assembly 20 and the second upper slide rail assembly 30 is achieved by the movement of the support seat 42 on the screw rod 41 .

[0040] Furthermore, the seat slide rail also includes a first drive mechanism and a second drive mechanism, which are arranged between the two sets of lower slide rails 10; the first drive mechanism is respectively connected to the two first sliding seats 43, and the second drive mechanism is respectively connected to the two second sliding seats 44.

[0041] Specifically, the first driving mechanism includes a first motor, a first transmission shaft and a first gearbox, one end of the first transmission shaft is connected to the first motor, and the other end is engaged with the screw rod 41 through the first gearbox; in addition, the second driving mechanism includes a second motor, a second transmission shaft and a second gearbox, one end of the second transmission shaft is connected to the second motor, and the other end is engaged with the screw rod 41 through the second gearbox.

[0042] Of course, what is described here is only an embodiment of driving the support seat 42 to move on the screw rod 41. It can also be driven by a chain, etc., and no specific limitation is made here.

[0043] In a possible implementation, the seat slide rail further includes a first controller 51 and a second controller 52 , wherein the first controller 51 is electrically connected to the first upper slide rail assembly 20 , and the second controller 52 is electrically connected to the second upper slide rail assembly 30 .

[0044] In this embodiment, a first soft stop point is provided at one end of the lower slide rail 10, and a second soft stop point is provided in the middle of the lower slide rail 10, and the first soft stop point and the second soft stop point are controlled by a first controller 51; a third soft stop point is provided at the other end of the lower slide rail 10, and a fourth soft stop point is provided in the middle of the lower slide rail 10, and the third soft stop point and the fourth soft stop point are controlled by a second controller 52;

[0045] There is an overlapped area between the travel from the first soft stop point to the second soft stop point and the travel from the third soft stop point to the fourth soft stop point. The advantage of such an arrangement is that the movement travel of the first upper slide rail assembly 20 and the second upper slide rail assembly 30 can be increased.

[0046] In addition, in order to prevent the first upper slide rail assembly 20 and the second upper slide rail assembly 30 from sliding out of the lower slide rail 10, in this embodiment, cross beams are provided on both sides of the lower slide rail 10 to limit the first upper slide rail assembly 20 and the second upper slide rail assembly 30 from sliding out.

[0047] Of course, sensors can also be set at both ends of the lower slide rail 10. When the first upper slide rail assembly 20 and the second upper slide rail assembly 30 move to both ends of the lower slide rail 10, when the sensors sense the first upper slide rail assembly 20 and the second upper slide rail assembly 30, the terminal cut-off controller cuts off the electrical connection, making the first upper slide rail assembly 20 and the second upper slide rail assembly 30 unable to move. Of course, what is described here is only one possible way to achieve this, including but not limited to this, and is not specifically limited here.

[0048] In addition, considering that when the first upper rail assembly 20 or the second upper rail assembly 30 moves, it is easy for the two to collide, which can be avoided by self-observation of the driver and passengers. Figure 4 As shown, the terminal controls the controller to drive the moving speed of the first motor or the second motor to reduce the damage caused by the collision.

[0049] The present embodiment also discloses a vehicle, comprising the above-mentioned seat rails, front seats and rear seats, wherein the front seats are connected to the first upper rail assembly 20, and the rear seats are connected to the second upper rail assembly 30. By moving the first upper rail assembly 20 and the second upper rail assembly 30 forward and backward, the movement strokes of the seat rails and the front seats are adjusted respectively.

[0050] Compared with the case where the front seats and rear seats use corresponding lower rails 10 respectively, the front seats and rear seats in this embodiment share one lower rail 10, overlapping the original separate lower rails 10 of the two, thereby increasing the sliding travel of the front seats and the rear seats.

[0051] The above is only a preferred implementation mode of the present application, and does not constitute any form of limitation to the present application. Although the present application has been disclosed as a preferred implementation mode as above, it is not used to limit the present application. Any technician familiar with this profession can make some changes or modify the technical contents disclosed above into equivalent implementation modes without departing from the scope of the technical solution of the present application. However, any simple modification, equivalent change and modification made to the above implementation modes based on the technical essence of the present application without departing from the content of the technical solution of the present application still fall within the scope of the technical solution of the present application.
