Technical Field

[0001] The present application relates to the field of automobile seats, and in particular to a multifunctional seat slide rail for automobiles. Background Art

[0002] With the advancement of the times and the update of technology, car seats have changed from manual adjustment seats to electric adjustment seats. Especially for some business cars, the functions of seats are magnified, such as adding leg rests and massage functions to the seats.

[0003] Business vehicles have large spaces and a large gap around each seat. However, existing car seats in business vehicles only provide electric forward and backward movement adjustment and adjustment of parts such as leg rests. The entire seat, such as the distance between two adjacent left and right seats, and the distance between the seat and the inside of the car, are difficult to adjust and the adjustment direction is single. Summary of the invention

[0004] In order to expand the adjustment range of the entire seat and enhance the diversity of seat adjustment directions, the present application provides a multifunctional seat slide rail for an automobile.

[0005] The present application provides a multifunctional seat slide rail for a car, which adopts the following technical solution:

[0006] A multifunctional seat slide rail for a car comprises two tracks, a first slider and a second slider are slidably disposed on a single track, a driving assembly for driving the first slider and the second slider to slide toward or away from each other is provided on one of the tracks, a mounting seat is provided between the two tracks, a first connecting rod is rotatably connected between the first slider and the mounting seat, a second connecting rod is rotatably connected between the second slider and the mounting seat, the first connecting rod and the second connecting rod are cross-arranged, and a car seat is provided on the mounting seat.

[0007] By adopting the above technical solution, the car seat is fixed on the mounting seat, and through the driving component, the angle between the first connecting rod and the second connecting rod gradually changes during the process of the first slider and the second slider sliding toward each other, so that the angle between the first connecting rod and the second connecting rod on the other track changes in the opposite direction, so that the entire mounting seat can be slid in a direction perpendicular to the length of the track, thereby realizing left and right adjustment of the entire seat, and improving the diversity of adjusting the movement direction of the seat.

[0008] Optionally, the driving assembly includes hollow blocks fixed at both ends of the inner cavity of the track, a first lead screw and a second lead screw rotatably connected between the two lead screws, and a first driving member arranged on the lead screw to drive the first lead screw and the second lead screw to rotate; the first lead screw is threadedly connected to the first slider, the first lead screw is slidably connected to the first slider, the second lead screw is threadedly connected to the second slider, and the second lead screw is slidably connected to the second slider.

[0009] By adopting the above technical solution, the first driving member makes the first screw and the second screw rotate synchronously. When the first screw and the second screw rotate synchronously in opposite directions, the first slider and the second slider slide synchronously toward or away from each other, thereby reducing or increasing the distance between the first slider and the second slider, and driving the car seat on the entire mounting seat to move along the direction perpendicular to the length of the track. When the first screw and the second screw rotate synchronously in the same direction, the entire mounting seat can slide as a whole along the length of the track.

[0010] Optionally, the first driving member includes a gear box fixed in the inner cavity of the block, a first worm rotatably connected to the inner cavity of the gear box, a first worm wheel rotatably connected to the inner cavity of the gear box, and a first motor fixed on the side wall of the track for driving the first worm to rotate, the first worm is meshed with the first worm wheel, one of the first worm wheels is coaxially fixedly connected to the first screw, the other first worm wheel is coaxially fixedly connected to the second screw, and the rotating shaft of the first motor is coaxially fixedly connected to the rotating shaft of the first worm.

[0011] By adopting the above technical solution, when the first lead screw and the second lead screw are driven to rotate synchronously, the rotating shaft of the first motor is driven to rotate, so that the first worm engages with the first worm wheel to rotate, thereby achieving synchronous rotation of one of the first worm wheels with the first lead screw and synchronous rotation of the other first worm wheel with the second lead screw.

[0012] Optionally, a connecting hole is formed through the side walls of the first slider and the second slider, and a plastic screw sleeve is integrally formed in the connecting hole. The first lead screw passes through the connecting hole of the first slider and is threadedly connected to the corresponding plastic screw sleeve, and the second lead screw passes through the connecting hole of the second slider and is threadedly connected to the corresponding plastic screw sleeve.

[0013] By adopting the above technical solution, the material of the plastic screw sleeve is high-hardness wear-resistant plastic. Compared with the mutual threaded transmission between metal materials, the first lead screw, the second lead screw and the plastic screw sleeve have a noise reduction effect during the threaded transmission process.

[0014] Optionally, a limiting hole is formed on the second connecting rod, and the first connecting rod is inserted into the limiting hole.

[0015] By adopting the above technical solution, during the interlaced sliding of the first connecting rod and the second connecting rod, the first connecting rod slides in the limiting hole, so that the first connecting rod is difficult to separate from the second connecting rod, thereby improving the stability of the left and right swinging and sliding of the entire mounting base.

[0016] Optionally, a linear slide rail is fixed in the inner cavity of the track, and the first slider and the second slider are both slidably connected to the linear slide rail.

[0017] By adopting the above technical solution, the linear slide rail improves the sliding stability of the first slider and the second slider in the inner cavity of the rail.

[0019] By adopting the above technical solution, the second worm is engaged with the second worm wheel to rotate through the second driving member, so that the second worm wheel and the steering shaft rotate synchronously, and the entire car seat can be rotated at a fixed angle.

[0020] Optionally, the second driving member includes a supporting shell fixed on the side wall of the receiving seat, and a second motor fixed on the side wall of the supporting shell, and the rotating shaft of the second motor is coaxially fixedly connected with the rotating shaft of the second worm.

[0021] By adopting the above technical solution, in the process of driving the second worm to rotate, the second motor is a servo motor, and the rotating shaft of the second worm rotates synchronously with the rotating shaft of the second motor, thereby realizing directional rotation adjustment of the entire car seat.

[0022] Optionally, a plurality of rollers are rotatably connected to the bottom surface of the mounting seat.

[0023] By adopting the above technical solution, the roller improves the sliding stability of the entire mounting seat on the one hand, and improves the bearing capacity of the entire mounting seat on the other hand.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. By cross-arranging the first connecting rod and the second connecting rod, the angle between the first connecting rod and the second connecting rod gradually changes, so that the angle between the first connecting rod and the second connecting rod on the other track changes in the opposite direction, so that the entire mounting seat can be slid along the direction perpendicular to the length of the track, and the left and right adjustment of the entire seat can be achieved, thereby improving the diversity of adjusting the movement direction of the seat.

[0026] 2. By setting the plastic screw sleeve, the noise generated during the movement and adjustment of the entire mounting base is reduced.

The cross-section of the track 1 is in a C shape, and there are two directions for the opening of the track 1. One setting method is that the openings of the two tracks 1 are arranged oppositely, and the other setting method is that the openings of the two tracks 1 are both vertically upward. The optimal setting is to set the opening of the track 1 vertically upward. The number of tracks 1 is set to two. During actual use, the two tracks 1 are arranged in parallel and fixedly installed on the bottom surface of the inner cavity of the automobile carriage.

[0036] Referring to Figure 1A first slider 2 and a second slider 3 are slidably arranged in the inner cavity of a single track 1, and a mounting seat 5 is arranged between the two tracks 1. A first connecting rod 6 is arranged between the first slider 2 and the mounting seat 5, one end of the first connecting rod 6 is rotatably hinged on the mounting seat 5, and the other end is hinged on the side wall of the first slider 2. A second connecting rod 7 is rotatably connected between the second slider 3 and the mounting seat 5, one end of the second connecting rod 7 is hinged on the side wall of the mounting seat 5, and the other end is hinged on the side wall of the second slider 3.

[0037] Reference Figure 1 The first connecting rod 6 and the second connecting rod 7 are arranged crosswise, and the second connecting rod 7 is assembled from two segmented connecting rods, so that a gap is left between the two segmented connecting rods, so that a limiting hole 18 is formed on the entire second connecting rod 7, and the first connecting rod 6 is inserted into the limiting hole 18. The setting of the limiting hole 18 makes it difficult for the first connecting rod 6 to separate from the second connecting rod 7 during the change of the angle between the first connecting rod 6 and the second connecting rod 7.

[0038] Reference Figure 1 , a driving assembly 4 for driving the first slider 2 and the second slider 3 to slide is provided on one set of tracks 1, so that when the first slider 2 and the second slider 3 are driven to slide on the track 1 provided with the driving assembly 4, the first slider 2 and the second slider 3 on the other track 1 slide passively. In order to further improve the sliding stability of the first slider 2 and the second slider 3 in the inner cavity of the track 1, a linear slide rail 19 is fixed in the inner cavity of the track 1, and each linear slide rail 19 is provided with two sliders, and the first slider 2 and the second slider 3 are fixedly connected to the corresponding sliders of the linear slide rail 19 respectively.

[0039] Reference Figure 1 and Figure 2 The driving assembly 4 includes a stopper 8, a first lead screw 9, a second lead screw 10, and a first driving member 11 arranged on the stopper 8 to drive the first lead screw 9 and the second lead screw 10 to rotate. There are four stoppers 8, and the number of the first lead screw 9 and the second lead screw 10 are both one. Stoppers 8 are fixed at both ends of each track 1. The stopper 8 is hollow. The first lead screw 9 and the second lead screw 10 are arranged in parallel and are both rotatably connected in the inner cavity of one of the tracks 1. The first lead screw 9 is threadedly connected to the corresponding first slider 2, and the second lead screw 10 is threadedly connected to the corresponding second slider 3.

[0040] Reference Figure 2 and Figure 3There are two first drive members 11, and both are arranged on the track 1 equipped with the first lead screw 9 and the second lead screw 10. The two first drive members 11 are respectively arranged on the block 8 at the end of the track 1. The first drive member 11 includes a gear box 12, a first worm 13, a first worm wheel 14 and a first motor 15. The gear box 12 is fixed in the inner cavity of the hollow block 8, the first worm 13 is rotatably connected in the inner cavity of the gear box 12, and the first worm wheel 14 is rotatably connected in the inner cavity of the gear box 12. The first worm 13 and the first worm wheel 14 are meshed with each other, and the first motor 15 is fixed on the outer wall of the track 1, and the rotating shaft of the first motor 15 is coaxially fixedly connected with the rotating shaft of the first worm 13.

[0041] Reference Figure 1 , Figure 2 and Figure 3 , so that in the process of driving the first lead screw 9 and the second lead screw 10 to rotate, one of the first worm gears 14 is coaxially fixedly connected to the first lead screw 9, and the other first worm gear 14 is coaxially fixedly connected to the second lead screw 10. When the first lead screw 9 and the second lead screw 10 are driven to rotate synchronously in opposite directions, the first slider 2 and the second slider 3 are moved away from or close to each other, thereby realizing the movement of the entire mounting seat 5 along the length direction perpendicular to the track 1. When the first lead screw 9 and the second lead screw 10 are driven to rotate synchronously and in the same direction, the entire mounting seat 5 can slide along the length direction of the track 1.

[0042] Reference Figure 1 , Figure 2 and Figure 4 In order to reduce transmission noise, a connecting hole 16 is formed through the side walls of the first slider 2 and the second slider 3, and a plastic screw sleeve 17 is integrally formed on the inner wall of the connecting hole 16 by injection molding. The first lead screw 9 passes through the connecting hole 16 formed on the side wall of the first slider 2 and is threadedly connected to the corresponding plastic screw sleeve 17, and the second lead screw 10 passes through the connecting hole 16 formed on the side wall of the second slider 3 and is threadedly connected to the corresponding plastic screw sleeve 17.

[0043] Reference Figure 5 At the same time, in order to make the entire seat capable of steering adjustment, a receiving seat 20 is fixed on the mounting seat 5, a steering shaft 21 is rotatably connected to the receiving seat 20, the steering shaft 21 and the receiving seat 20 are rotatably connected via a ball bearing, a second worm gear 22 is coaxially fixed to the outer side of the steering shaft 21, a second worm 23 for driving the second worm gear 22 to rotate is rotatably connected to the receiving seat 20, and the second worm 23 and the second worm gear 22 are meshed with each other. The car seat is fixed to the upper end of the rotating shaft of the second worm gear 22, and a second driving member 24 for driving the second worm 23 to rotate is provided on the receiving seat 20, so as to realize the fixed angle rotation adjustment of the entire car seat.

[0044] Reference Figure 5The second driving member 24 includes a supporting shell 25 and a second motor 26. The supporting shell 25 is fixed on the side wall of the receiving seat 20. The second motor 26 is fixed on the receiving shell. The second motor 26 is a servo motor. The rotating shaft of the second motor 26 is coaxially fixedly connected with the second worm 23. The rotating shaft of the second motor 26 is driven to rotate, so that the second worm 23 meshes with the second worm wheel 22 and rotates at a fixed angle, thereby realizing the adjustment of the steering of the seat.

[0045] Reference Figure 5 In order to further improve the bearing capacity of the entire mounting seat 5 and the sliding stability, a roller 27 is rotatably connected to the bottom of the mounting seat 5. The roller 27 can be a universal wheel, so that when the user sits on the car seat, the center of gravity of the entire body is located on the mounting seat 5, and most of the weight is pressed on the top of the roller 27, so that the roller 27 plays a supporting role and also makes it easier for the mounting seat 5 to slide.

[0046] The implementation principle of a multifunctional seat slide for a car in an embodiment of the present application is as follows: the car seat slide in the present application has three adjustment methods. During actual use, when the entire car seat needs to be moved and adjusted along the length direction of the track 1, the first motor 15 drives the first screw 9 and the second screw 10 to rotate synchronously and in the same direction, thereby realizing the sliding of the entire mounting base 5 along the length direction of the track 1.

[0047] When it is necessary to achieve sliding adjustment of the entire car seat along the direction of the spacing width between the two rails 1, the first motor 15 drives the first screw 9 and the second screw 10 to rotate synchronously in opposite directions, so that the first slider 2 and the second slider 3 slide toward or away from each other on the rail 1, thereby achieving movement and adjustment of the entire seat along a direction perpendicular to the length of the rail 1.

[0048] When the entire car seat needs to be rotated and adjusted, the second motor 26 is used to make the second worm 23 engage with the second worm wheel 22 to rotate, so that the entire steering shaft 21 can be rotated, thereby adjusting the steering of the car seat.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
