[0049] The embodiments of the present application provide an assembly device for a seat, which is used for installing vehicle seats, especially suitable for installing seats of some trial-production vehicles without dedicated production lines. Among them, the vehicle can be a hybrid electric vehicle, a plug-in hybrid vehicle, an extended-range electric vehicle, a fuel vehicle, etc. The vehicle can also be a sedan, a truck, a bus, a lorry, a trailer, etc.

[0050] The seat of the vehicle includes a backrest and a seat cushion. The backrest is connected to the seat cushion at a certain angle, and there is a gap between the backrest and the seat cushion, which enables the angle between the backrest and the seat cushion to be adjustable.

[0051] In some embodiments, please refer to Figure 1 and Figure 2 , the assembly device may include a grasping device 10. The seat is grasped by the grasping device 10, and then the seat is moved to the corresponding installation position of the vehicle for assembly. Compared with manually carrying the seat, it can save time and effort and improve the assembly efficiency of the seat.

[0052] In some embodiments, refer to Figure 3 and Figure 4 , Figure 3 is a schematic structural diagram of the grasping device 10 provided by the embodiments of the present application in the first state, Figure 4 is a schematic structural diagram of the grasping device 10 provided by the embodiments of the present application in the second state. The grasping device 10 includes a first grasping structure 1 and a second grasping structure 2. At least part of the first grasping structure 1 and at least part of the second grasping structure 2 can pass through the gap between the backrest and the seat cushion of the seat, and can move away from each other along the height direction of the seat to tighten between the seat cushion and the backrest. It should be noted that the directions in the present application are all relative to the seat in the state where the grasping device 10 grasps the seat.

[0053] In the above solution, during the process of the grasping device 10 grasping the seat, the first grasping structure 1 and the second grasping structure 2 can be passed through the gap between the seat backrest and the seat cushion, and then the first grasping structure 1 and the second grasping structure 2 are controlled to move away from each other along the height direction of the seat, so that the first grasping structure 1 and the second grasping structure 2 are tightened between the seat cushion and the backrest. At this time, since the first grasping structure 1 and the second grasping structure 2 are tightened between the seat cushion and the backrest, the connection between the grasping device 10 and the seat can be made more firm, so that the seat can be prevented from shaking or shifting, thereby facilitating the accurate alignment of the seat at the seat installation position on the vehicle body and improving the installation efficiency of the seat.

[0054] In some examples, the first grasping structure 1 and the second grasping structure 2 move away from each other in the height direction of the seat. It can be that both the first grasping structure 1 and the second grasping structure 2 move in the height direction of the seat. It can also be that the first grasping structure 1 remains stationary while the second grasping structure 2 moves. Or the second grasping structure 2 remains stationary while the first grasping structure 1 moves. In this application, an exemplary description is given with the second grasping structure 2 remaining stationary and the first grasping structure 1 moving relative to the first grasping structure 1.

[0055] In some embodiments, the first grasping structure 1 includes a rotating part 11 and a tightening part 12 connected to the rotating part 11. The rotating part 11 is rotatably connected to the second grasping structure 2 so that the tightening part 12 swings away from the second grasping structure 2. The first grasping structure 1 is provided with the rotating part 11 and the tightening part 12, and the rotating part 11 is rotatably connected to the second grasping structure 2. When the rotating part 11 rotates relative to the second grasping structure 2, the tightening part 12 will swing relative to the second grasping structure 2, so that the tightening part 12 and the second grasping structure 2 move away from each other to tighten between the backrest and the seat cushion, realizing a stable connection between the grasping structure and the seat. The structure of the above grasping structure is simple, which is convenient for stably grasping the seat.

[0056] In some examples, the rotating part 11 of the first grasping structure 1 can be rotatably connected to the second grasping structure 2 through a hinge, a connecting shaft, etc., so as to realize the swing of the tightening part 12 relative to the second grasping structure 2 through the rotation of the rotating part 11.

[0057] In some embodiments, refer to Figure 3 and Figure 4 , the second grasping structure 2 includes a grasping part 21, and the grasping part 21 and the tightening part 12 can pass through the gap. The tightening part 12 can swing between a first position and a second position relative to the grasping part 21. When the tightening part 12 is in the first position, at least part of the tightening part 12 is located on one side of the grasping part 21 in the height direction of the seat to tighten between the seat cushion and the backrest. In this way, it is convenient for the grasping device 10 to be stably connected to the seat.

[0058] When the tightening part 12 is in the second position, the tightening part 12 and the grasping part 21 are arranged in the width direction of the seat. In this way, when the tightening part 12 is in the second position, the overall size of the tightening part 12 and the grasping part 21 in the height direction of the seat is smaller, so that it is convenient for the tightening part 12 and the grasping part 21 to extend into the gap between the backrest and the seat cushion.

[0059] Among them, the second position of the tightening part 12 relative to the grasping part 21 can be referred to Figure 3 . Figure 3The middle tightening part 12 and the grasping part 21 are both plate-like structures. At this time, the tightening part 12 and the grasping part 21 are generally in a relatively parallel state, and the tightening part 12 and the grasping part 21 are arranged along the width direction of the seat, which is convenient for passing the tightening part 12 and the grasping part 21 through the gap between the backrest and the seat cushion.

[0060] The first position of the tightening part 12 relative to the grasping part 21 can be referred to Figure 4 , Figure 4 The middle tightening part 12 and the grasping part 21 are also both plate-like structures. At this time, there is a certain angle between the tightening part 12 and the grasping part 21, and this angle is formed after the tightening part 12 swings relative to the grasping part 21. At this time, the gap between the tightening part 12 and the grasping part 21 becomes larger to tighten between the backrest and the seat cushion. Through the two positions where the tightening part 12 swings relative to the grasping part 21, the grasping of the seat is realized, with a simple structure and the ability to stably grasp the seat, improving work efficiency.

[0061] In some examples, when the tightening part 12 is in the second position relative to the grasping part 21, the angle between the tightening part 12 and the grasping part 21 can be 5°, 10°, 15°, etc.

[0062] In some other embodiments, the grasping part and the tightening part 12 can also be rod-like structures, wedge-shaped structures, etc., and the present application does not make specific limitations on this.

[0063] In some embodiments, the second grasping structure 2 further includes a supporting part 211, and the grasping part 21 includes a first grasping part 212 and a second grasping part 213 connected to the supporting part 211. Among them, the supporting part 211 can be a plate-like structure, a supporting seat structure, a frame 6 structure, etc. The present application does not make specific limitations on this.

[0064] The first grasping part 212 and the second grasping part 213 are arranged along the width direction of the seat. When the tightening part 12 is in the second position, the tightening part 12 is located between the first grasping part 212 and the second grasping part 213. The grasping part 21 includes the first grasping part 212 and the second grasping part 213, and when the tightening part 12 is in the second position, the first grasping part 212 and the second grasping part 213 are located on both sides of the tightening part 12. At this time, the tightening part 12 tightens the backrest of the seat, and the first grasping part 212 and the second grasping part 213 tighten the seat cushion on both sides of the tightening part 12. The first grasping part 212 and the second grasping part 213 form supports on both sides of the tightening part 12, making the forces on both sides of the tightening part 12 balanced, preventing the seat from tilting during the grasping process, and improving the grasping stability.

[0065] In some examples, the first grasping portion 212 and the second grasping portion 213 are simultaneously connected to the supporting portion 211 and are located on both sides of the supporting portion 211. A gap is provided between the first grasping portion 212 and the second grasping portion 213, and the tightening portion 12 is located within the gap between the first grasping portion 212 and the second grasping portion 213.

[0066] In other embodiments, the second grasping structure 2 only includes the grasping portion 21, and the number of the grasping portions 21 can be one or more.

[0067] In other embodiments, both the first grasping structure 1 and the second grasping structure 2 are plate-like structures so as to be easily passed through the gap between the backrest and the seat cushion of the seat. Alternatively, the first grasping structure 1 and the second grasping structure 2 can also be rod-like structures, and flat guiding structures can be provided at the ends of the rod-like structures so that the first grasping structure 1 and the second grasping structure 2 of the rod-like structures can be smoothly passed through the gap between the backrest and the seat cushion.

[0068] In other embodiments, the relative movement of the first grasping structure 1 and the second grasping structure 2 in the height direction of the seat can be achieved by the relative translation of the first grasping structure 1 and the second grasping structure 2. For example, both the first grasping structure 1 and the second grasping structure 2 are plate-like structures, one of the first grasping structure 1 and the second grasping structure 2 is provided with an electromagnet, and the other is provided with a permanent magnet, etc. When the grasping device 10 does not tighten the backrest and the seat cushion, the first grasping structure 1 and the second grasping structure 2 can be stacked. When it is necessary to tighten the backrest and the seat cushion, the electromagnet can be energized so that the electromagnet and the permanent magnet interact with each other to push the first grasping structure 1 and the second grasping structure 2 to move away from each other.

[0069] This application takes the relative rotation of the first grasping structure 1 and the second grasping structure 2 as an example for illustration.

[0070] In some embodiments, the grasping device 10 further includes a pressure sensor, and the pressure sensor is connected to the tightening portion 12 for detecting the pressure between the tightening portion 12 and the backrest. After the pressure sensor is provided, by detecting the pressure between the tightening portion 12 and the backrest through the pressure sensor, the grasping state of the grasping device 10 on the seat can be identified by the pressure detected by the pressure sensor, and the automation degree of the device can be improved.

[0071] In some examples, when the tightening portion 12 is located at the first position relative to the grasping portion 21, the pressure sensor can be located on the side of the tightening portion 12 facing away from the grasping portion 21.

[0072] In other examples, the pressure sensor can be disposed on the lower surface of the grasping portion 21, where the lower surface of the grasping portion 21 is the side surface of the grasping portion 21 facing away from the tightening portion 12 when the tightening portion 12 is located at the first position relative to the grasping portion 21.

[0073] In some embodiments, see Figure 3 The gripping device 10 further includes a first rotating shaft 3, the first rotating shaft 3 is rotatably connected to the second gripping structure 2, and the rotating part 11 is rotatably connected to the first rotating shaft 3. The rotating part 11 is rotatably connected to the second gripping structure 2 through the first rotating shaft 3, and has a simple structure and is easy to produce.

[0074] In some examples, the first rotating shaft 3 is rotatably connected to the second gripping structure 2 , and the rotating portion 11 is fixedly connected to the first rotating shaft 3 .

[0075] In some other embodiments, the first rotating shaft 3 is fixedly connected to the second gripping structure 2, the rotating portion 11 is provided with a connecting hole, and the rotating portion 11 is rotatably connected to the first rotating shaft 3 through the connecting hole.

[0076] In some embodiments, the gripping device 10 further includes a first driving member 43, which is in transmission connection with the first gripping structure 1 and is used to drive the first gripping structure 1 to rotate. The first driving member 43 is connected to the first gripping structure 1, and the tightening portion 12 of the first gripping structure 1 is driven to swing between the first position and the second position relative to the gripping portion 21, so as to realize automatic gripping of the seat and improve work efficiency.

[0077] In some examples, the first driving member 43 may be a rotary motor, a rotary cylinder, or the like.

[0078] In some embodiments, the gripping device 10 further includes a first transmission structure, which is transmission-connected between the first driving member 43 and the first gripping structure 1, so that the first driving member 43 drives the first gripping structure 1 to rotate through the first transmission structure. The first driving member 43 drives the first gripping structure 1 to rotate through the first transmission structure, thereby achieving automatic gripping of the seat and improving work efficiency.

[0079] In some embodiments, the first gripping structure 1 further includes a connecting portion 13, which is connected to the rotating portion 11 and is located on one side of the tightening portion 12 in the height direction of the seat, and the first transmission structure is connected to the connecting portion 13 and can push and pull the connecting portion 13 along the length direction of the seat. The connecting portion 13 is provided on the rotating portion 11, and the first transmission structure is connected to the connecting portion 13, and drives the rotating portion 11 to rotate by pushing and pulling the connecting portion 13, thereby driving the tightening portion 12 of the first gripping structure 1 to swing between the first position and the second position with respect to the gripping portion 21, so as to realize automatic gripping of the seat and improve work efficiency.

[0080] In some embodiments, see Figure 5, the first transmission structure includes a first transmission member 41 and a second transmission member 42. The first driving member 43 is in transmission connection with the first transmission member 41 and is used to drive the first transmission member 41 to rotate. The second transmission member 42 is movably connected to the connecting portion 13. The cooperation of the first transmission member 41 and the second transmission member 42 can make the second transmission member 42 move along the length direction of the seat. The first driving member 43 drives the second transmission member 42 to move along the length direction of the seat through the first transmission member 41, thereby driving the rotating portion 11 to move along the length direction of the seat, and then driving the tightening portion 12 to rotate through the rotating portion 11. The structure is simple and the production cost is reduced.

[0081] In some embodiments, the first transmission member 41 is rotatably connected to the second grasping structure 2, and the first transmission member 41 is provided with an external thread. The second transmission member 42 is provided with a first through hole, and the inner wall surface of the first through hole is provided with an internal thread. The first transmission member 41 passes through the first through hole, and the external thread is screwed with the internal thread. The second transmission member 42 and the connecting portion 13 can slide relative to each other in a first direction, and the first direction is consistent with the arrangement direction of the connecting portion 13 and the rotating portion 11. The first transmission member 41 is provided with an external thread, the second transmission member 42 is provided with a first through hole, the first through hole is provided with an internal thread, the external thread of the first transmission member 41 is connected to the internal thread of the second transmission member 42, and the second transmission member 42 can slide in the first direction.

[0082] When the first driving member 43 drives the first transmission member 41 to rotate, through the cooperation of the internal thread and the external thread, the second transmission member 42 can be driven to move along the length direction of the seat, so that the second transmission member 42 generates a force on the connecting portion 13, thereby driving the rotating portion 11 to rotate. At the same time, the second transmission member 42 can slide in the first direction, which can prevent the second transmission member 42 from being stuck with the connecting portion 13 to ensure that the connecting portion 13 can smoothly drive the rotating portion 11 to rotate. Driving the rotating portion 11 to rotate through the threaded structure has a simple structure and is stable and reliable.

[0083] Wherein, the length direction of the seat is consistent with the length direction of the vehicle, the width direction of the seat is consistent with the width direction of the vehicle, and the height direction of the seat is consistent with the height direction of the vehicle.

[0084] In some examples, the first transmission member 41 can be a rod-shaped structure. Or, a part of the first transmission member 41 is a rod-shaped structure, and the other part is a plate-shaped structure, a block-shaped structure, etc. The second transmission member 42 can be a nut or a block-shaped structure with an internal thread, etc.

[0085] In some examples, the connecting portion 13 is provided with a sliding groove 131 that extends in the first direction. The second transmission member 42 is rotatably connected to the sliding groove 131 and can slide along the length direction of the sliding groove 131. At this time, the length direction of the sliding groove 131 is the first direction. It should be noted that the rotation direction of the second transmission member 42 relative to the sliding groove 131 is inconsistent with the rotation direction of the first transmission member 41. The second transmission member 42 can be rotatably connected to the sliding groove 131 through a rotating shaft, and the axis direction of the rotating shaft can extend along the width direction of the seat.

[0086] In some other examples, the connecting portion 13 can be provided with a guide rail that extends in the first direction, and a slidable slider is provided on the guide rail. The second transmission member 42 is connected to the slider.

[0087] In some embodiments, the first driving member 43 can be directly connected to the first transmission member 41 to drive the first transmission member 41 to rotate. In some other embodiments, the first driving member 43 can also be drivingly connected to the first transmission member 41 through a gear transmission structure, a belt transmission structure, a chain transmission structure, etc. to drive the first transmission member 41 to rotate.

[0088] In some other embodiments, the first transmission structure can further include a transmission gear, and the second transmission member 42 can further include a transmission rack and a connecting rod. The transmission rack is slidably connected to the support portion 211 of the second grasping structure 2 along the length direction of the seat. One end of the connecting rod is rotatably connected to the transmission rack, and the other end of the connecting rod is rotatably connected to the connecting portion 13. The transmission gear meshes with the transmission rack and is connected to the first driving member 43. The first driving member 43 can drive the transmission rack to move through the transmission gear, thereby generating a force on the connecting portion 13 through the swing of the connecting rod to drive the rotating portion 11 to rotate.

[0089] In some embodiments, the connecting portion 13 can be a rod-shaped structure, a plate-shaped structure, etc. One end of the connecting portion 13 facing the tightening portion 12 and one end of the tightening portion 12 facing the connecting portion 13 form the rotating portion 11, or the rotating portion 11 is a rod-shaped structure, a block-shaped structure, etc.

[0090] In some other embodiments, the first driving member 43 can be directly connected to the rotating portion 11 to drive the rotating portion 11 to rotate, thereby driving the tightening portion 12 to swing.

[0091] In some other embodiments, the first driving member 43 can also be connected to the rotating portion 11 through a gear transmission structure, a belt transmission structure, a chain transmission structure, etc. to drive the rotating portion 11 to rotate, thereby driving the tightening portion 12 to swing.

[0092] In some embodiments, refer to Figure 3, the second grasping structure 2 includes a supporting portion 211 and a grasping portion 21 connected to the supporting portion 211. The grasping portion 21 and the tightening portion 12 can pass through the gap to tighten the seat cushion and the backrest. The grasping device 10 further includes a limiting structure 5, and at least a part of the limiting structure 5 is located on the upper side of the grasping portion 21 and the supporting portion 211 in the height direction of the seat, and is used to limit the backrest. After the grasping portion 21 and the tightening portion 12 cooperate to tighten the gap between the backrest and the seat cushion of the seat, the position of the seat backrest is abutted and limited by the limiting structure 5, so as to improve the stability of the grasping device 10 when grasping the seat, and prevent the angle change between the backrest and the seat cushion during the grasping process, so as to maintain the stability of the seat.

[0093] In some examples, the limiting structure 5 is connected to the supporting portion 211, and the backrest of the seat is abutted by the limiting structure 5 to improve the stability of the grasping process.

[0094] In some examples, the limiting structure 5 may include a limiting plate, and the backrest is abutted by the limiting plate to prevent the backrest from rotating relative to the seat cushion.

[0095] In some embodiments, refer to Figure 3 and Figure 6 , the limiting structure 5 includes a limiting member 51 and a connecting member 52. The limiting member 51 is located on the upper side of the grasping portion 21 and the tightening portion 12 in the height direction of the seat, and is used to limit the backrest. One end of the connecting member 52 is connected to the limiting member 51, and the other end of the connecting member 52 is rotatably connected to the supporting portion 211.

[0096] In this way, during the process of the grasping portion 21 and the tightening portion 12 extending into the gap between the backrest and the seat cushion, the limiting member 51 can contact the backrest. As the grasping portion 21 and the tightening portion 12 continuously extend into the gap between the backrest and the seat cushion, the extrusion force between the limiting member 51 and the backrest gradually increases. At this time, by rotating the connecting member 52 relative to the supporting portion 211, the limiting member 51 can be better fitted with the backrest, so that the limiting member 51 can better limit and support the backrest. And by rotatably connecting the connecting member 52 with the supporting portion 211, the angle between the limiting portion and the backrest can be automatically adjusted, improving the adaptability to different seat models and expanding the use range of the grasping device 10.

[0097] In some examples, one end of the connecting member 52 is rotatably connected to the limiting member 51 through a fourth rotating shaft 53. When the limiting member 51 contacts the backrest, the connecting member 52 can automatically rotate under the action of the limiting member 51 and the backrest, so that the limiting member 51 reaches the best fitting state with the backrest.

[0098] In some examples, the connecting member 52 and the supporting portion 211 are rotatably connected by a third rotating shaft 54. An arc-shaped limiting hole 55 is provided in the supporting portion 211. The connecting member 52 is provided with a limiting post, and the limiting post is embedded in the arc-shaped limiting hole 55 and can slide along the arc-shaped limiting hole 55. By the cooperation of the arc-shaped limiting hole 55 and the limiting post, the rotation range of the connecting member 52 is limited, preventing the cooperation with the backrest from failing due to excessive rotation angle.

[0099] In some examples, the limiting member 51 can be in a plate-like structure, a block-like structure, etc., and the connecting member 52 can be in a rod-like structure, an L-shaped structure, etc.

[0100] In some examples, the number of the connecting members 52 can be two. The two connecting members 52 are respectively connected to both sides of the limiting member 51 in the width direction of the seat to stably support the limiting member 51.

[0101] In some embodiments, referring to Figure 3 、 Figure 4 and Figure 6 ,the grasping device 10 further includes an elastic member 56. The elastic member 56 is connected between the connecting member 52 and the supporting portion 211 and is used to generate a force on the connecting member 52 towards the backrest. By the elastic force of the elastic member 56, a force is generated on the connecting member 52 towards the backrest. When the limiting member 51 contacts the backrest, under the action of the force generated by the elastic member 56 on the connecting member 52, the connecting member 52 can generate a force on the limiting member 51 towards the backrest, so that the limiting member 51 can closely abut against the backrest, improving the limiting and supporting effects on the backrest, preventing the backrest from rotating relative to the seat cushion during the grasping process of the seat, and improving the stability of grasping.

[0102] In some examples, the elastic member 56 can be a tension spring. One end of the tension spring is connected to the connecting member 52, and the other end is connected to the supporting portion 211.

[0103] In some other examples, the elastic member 56 can also be an elastic structure such as latex, rubber, silicone rubber, etc.
