Description

Technical Field

[0001] This utility model relates to the field of vehicle assembly technology, and in particular to a vehicle seat gripping device. Background Technology

[0002] With the development of industrial technology, vehicle seat assembly has gradually shifted from manual assembly to automated gripping device assembly. These devices pick up seats placed on a workbench and move them into the vehicle for installation. However, existing vehicle seat gripping devices typically can only grip one seat at a time. When assembling rear seats, multiple seats need to be repeatedly gripped, moved, and installed, which is time-consuming, labor-intensive, and inefficient. While combining multiple gripping devices can improve assembly efficiency by gripping multiple seats individually, this method is only suitable for a single vehicle model, lacking versatility. Utility Model Content

[0003] The main purpose of this utility model is to propose a vehicle seat gripping device, which aims to solve the technical problem of poor versatility of existing vehicle seat gripping devices.

[0004] To achieve the above objectives, the vehicle seat gripping device proposed in this utility model includes a flipping mechanism, a lifting mechanism, and a gripping mechanism. The lifting mechanism is connected to the flipping mechanism and is used to drive the flipping mechanism to move vertically up and down. The gripping mechanism includes a bracket, multiple linear servo modules, and multiple gripping components. The bracket is rotatably mounted on the flipping mechanism, and the multiple linear servo modules are spaced apart on the bracket along a first horizontal direction. Each linear servo module is connected to a gripping component, and the linear servo module is used to drive the gripping component to slide along the first horizontal direction to adjust the distance between the gripping component and any adjacent gripping component. The flipping mechanism can drive the bracket to rotate around the first horizontal direction, so that each linear servo module drives the gripping component connected to it to rotate between a gripping position and a relaxed position. When the gripping component is in the gripping position and the relaxed position, it can grip and relax the seat respectively.

[0005] In one embodiment, the gripping assembly includes a connecting arm and a gripping bucket. One end of the connecting arm is slidably connected to the linear servo module. The two opposite ends of the gripping bucket are a first end and a second end, respectively. The first end is connected to the end of the connecting arm away from the linear servo module, and the second end is used to insert into the gap formed between the backrest and the seat cushion of the seat to grip the seat when in the gripping position.

[0006] In one embodiment, the gripping assembly further includes a telescopic cylinder and a hinge shaft extending along the first horizontal direction. The first end is rotatably connected to the end of the connecting arm away from the linear servo module via the hinge shaft. The telescopic cylinder is connected to the gripping bucket and is used to drive the gripping bucket to rotate relative to the connecting arm about the hinge shaft when the gripping assembly is in the relaxed position, so that the second end moves closer to the connecting arm.

[0007] In one embodiment, a positioning post is provided at the end of the connecting arm away from the linear servo module, and a positioning hole is provided at the first end. The first end is inserted and engaged with the positioning post through the positioning hole and is fastened to the end of the connecting arm away from the linear servo module by fasteners.

[0008] In one embodiment, the bucket is a C-shaped bucket, and a flexible contact strip is provided on the inner side of the second end.

[0009] In one embodiment, the flipping mechanism includes a column, a drive gear, a driven gear, and a flipping drive member. One end of the column is connected to the lifting mechanism, and the other end of the column is rotatably mounted with the drive gear. The driven gear meshes with the drive gear, and the shaft of the driven gear is connected to the bracket. The flipping drive member can drive the drive gear to rotate around the first horizontal direction, so as to drive the bracket to rotate around the first horizontal direction through the driven gear.

[0010] In one embodiment, the flipping drive is a servo motor, and the flipping mechanism further includes a reducer and a brake. The output shaft of the servo motor is connected to the drive gear through the reducer to drive the drive gear to rotate along the first horizontal direction. The brake is connected to the output shaft to brake the drive gear through the output shaft.

[0011] In one embodiment, one end of the column is provided with a flange for connection with the lifting mechanism, and a plurality of reinforcing ribs spaced circumferentially along the flange are connected between the flange and the column.

[0012] In one embodiment, a limiting mechanism is provided between any two adjacent gripping components, and the limiting mechanism is used on both sides along the first horizontal direction to limit the two seats gripped by the two gripping components.

[0013] In one embodiment, the limiting mechanism includes two limiting plates spaced apart along the first horizontal direction, and the two limiting plates can respectively abut and limit the two seats grasped by the two gripping components.

[0014] The vehicle seat gripping device proposed in this utility model uses a lifting mechanism to drive a flipping mechanism to rise and fall, thereby adjusting the height of multiple gripping components. The flipping mechanism drives a bracket to rotate around a first horizontal direction, causing the multiple gripping components to rotate between gripping and releasing positions. This allows multiple gripping components to simultaneously grip and release multiple seats, enabling simultaneous gripping of multiple rear seats in a vehicle, resulting in high assembly efficiency. Each gripping component is connected to the bracket via a linear servo module. Each linear servo module can drive the gripping component to slide along the first horizontal direction. Multiple linear servo modules individually drive their respective gripping components to adjust the distance between any two adjacent gripping components. When gripping vehicle seats of different models, the distance between adjacent gripping components can be flexibly adjusted according to the distance between two adjacent seats, ensuring that the distance between the two gripping components matches the distance between the two seats. This allows the gripping device proposed in this utility model to adapt to the seat assembly work of different vehicle models, effectively improving the versatility of the gripping device and thus saving production costs.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0025] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0026] In this utility model, the descriptions of directions such as "up", "down", "left", and "right" are as follows: Figure 1 The directions shown are for reference only and are used to interpret the location. Figure 1The relative positional relationship between the components in the shown posture is such that if the specific posture changes, the directional indication will also change accordingly.

[0027] Existing vehicle seat gripping devices typically grip only one seat at a time. When assembling rear seats, multiple rear seats need to be repeatedly gripped, moved, and installed, which is time-consuming, labor-intensive, and inefficient. When multiple gripping devices are used in combination, the spacing between them is fixed, which can only be adapted to the gripping and assembly of seats for a single vehicle model, resulting in poor versatility. This leads to the need to frequently adjust the spacing of multiple gripping devices on multi-vehicle production lines, significantly increasing production and time costs.

[0028] This utility model proposes a vehicle seat gripping device, including a flipping mechanism 10, a lifting mechanism, and a gripping mechanism 20. The lifting mechanism is connected to the flipping mechanism 10 and is used to drive the flipping mechanism 10 to move vertically up and down. The gripping mechanism 20 includes a bracket 21, multiple linear servo modules 22, and multiple gripping components 23. The bracket 21 is rotatably mounted on the flipping mechanism 10, and the multiple linear servo modules 22 are spaced apart on the bracket 21 along a first horizontal direction. Each linear servo module 22 is connected to a gripping component 23, and the linear servo module 22 is used to drive the gripping component 23 to slide along the first horizontal direction to adjust the distance between the gripping component 23 and any adjacent gripping component 23. The flipping mechanism 10 can drive the bracket 21 to rotate around the first horizontal direction, so that the gripping components 23 connected to it can rotate between a gripping position and a relaxing position through each linear servo module 22. When the gripping component 23 is in the gripping position and the relaxing position, it can grip and relax the seat respectively.

[0029] Please see Figure 1 , Figure 1 The left and right directions in the middle are the first horizontal directions. Figure 1The vertical direction is defined as the up-down direction. A lifting mechanism is connected above the tilting mechanism 10, and the bracket 21 of the gripping mechanism 20 is mounted on the tilting mechanism 10. The lifting mechanism can drive the tilting mechanism 10 to rise and fall, thereby causing the gripping mechanism 20 to rise and fall. The tilting mechanism 10 can drive the bracket 21 to rotate axially around the first horizontal direction, thereby causing multiple linear servo modules 22 and multiple gripping components 23 mounted on the bracket 21 to rotate synchronously, so that each gripping component 23 rotates between the gripping position and the release position. The number of gripping components 23 corresponds to the number of seats. During the assembly of the vehicle seats, the lifting mechanism first lowers the gripping mechanism 20, causing each gripping component 23 to gradually approach its corresponding seat. Simultaneously, each linear servo module 22 drives its connected gripping component 23 to slide along the first horizontal direction, ensuring that the distance between any two adjacent gripping components 23 matches the distance between two adjacent seats. This aligns the gripping components 23 with their respective seats. Then, the flipping mechanism 10 rotates the gripping components 23 synchronously, moving them from a relaxed position to a gripping position and gripping the corresponding seats. This allows multiple gripping components 23 to grip multiple seats, facilitating their installation into the vehicle. After the seats are installed, the flipping mechanism 10 rotates the gripping components 23 from the gripping position to the relaxed position, releasing the corresponding seats. The lifting mechanism then raises the gripping components 23, moving them away from their respective seats, completing the vehicle seat assembly process.

[0030] The vehicle seat gripping device proposed in this utility model uses a lifting mechanism to drive a flipping mechanism 10 to rise and fall, which in turn drives a gripping mechanism 20 to rise and fall, thereby adjusting the height of multiple gripping components 23. The flipping mechanism 10 drives a bracket 21 to rotate around a first horizontal direction, causing the multiple gripping components 23 to rotate between gripping and releasing positions. This allows the multiple gripping components 23 to simultaneously grip and release multiple seats, enabling simultaneous gripping of multiple rear seats in a vehicle, resulting in high assembly efficiency. Each gripping component 23 is connected to the bracket 21 via a linear servo module 22. Each linear servo module 22 can drive the gripping component 23 to slide along the first horizontal direction. By having multiple linear servo modules 22 drive their respective gripping components 23 to slide, the distance between any two adjacent gripping components 23 can be adjusted. When gripping vehicle seats of different models, the distance between two adjacent gripping components 23 can be flexibly adjusted according to the distance between two adjacent seats, so that the distance between the two adjacent gripping components 23 matches the distance between the two seats. This allows the gripping device proposed in this utility model to adapt to the seat assembly work of different vehicle models, effectively improving the versatility of the gripping device and thus saving production costs.

[0031] In one embodiment, the gripping assembly 23 includes a connecting arm 231 and a gripping bucket 232. One end of the connecting arm 231 is slidably connected to the linear servo module 22. The two opposite ends of the gripping bucket 232 are a first end 2321 and a second end 2322, respectively. The first end 2321 is connected to the end of the connecting arm 231 away from the linear servo module 22. The second end 2322 is used to insert into the gap formed between the backrest and the cushion of the seat to grip the seat when in the gripping position.

[0032] During the gripping process, the linear servo module 22 drives the connecting arm 231 to slide along the first horizontal direction, causing the gripping bucket 232 to move synchronously, so that the second end 2322 of the gripping bucket 232 is precisely aligned with the gap formed between the seat back and the seat cushion. When the gripping assembly 23 is aligned with the corresponding seat, the flipping mechanism 10 drives the gripping assembly 23 to rotate around the first horizontal direction, and the second end 2322 of the gripping bucket 232 inserts into the gap of the seat. When the lifting mechanism drives the gripping bucket 232 to rise, the second end 2322 abuts against the seat back, thereby achieving stable gripping of the seat. After the seat is assembled, the flipping mechanism 10 drives the gripping assembly 23 to rotate in the opposite direction, and the second end 2322 of the gripping bucket 232 disengages from the gap of the seat, completing the release action. The insertion depth and angle of the grab bucket 232 are precisely controlled by the sliding accuracy of the linear servo module 22 and the rotation angle of the tilting mechanism 10, ensuring that the grabbing and releasing actions of multiple grab buckets 232 are consistent and that multiple seats are grabbed simultaneously, effectively improving the accuracy and consistency of seat grabbing.

[0033] In one embodiment, the gripping assembly 23 further includes a telescopic cylinder and a hinge shaft 233 extending along a first horizontal direction. The first end 2321 is rotatably connected to the end of the connecting arm 231 away from the linear servo module 22 via the hinge shaft 233. The telescopic cylinder is connected to the gripping bucket 232. The telescopic cylinder is used to drive the gripping bucket 232 to rotate relative to the connecting arm 231 about the hinge shaft 233 when the gripping assembly 23 is in the relaxed position, so that the second end 2322 approaches the connecting arm 231.

[0034] Please see Figure 2 and Figure 3 The first end 2321 of the grab bucket 232 is hinged to the connecting arm 231 via a hinge shaft 233, allowing the grab bucket 232 to rotate around the hinge shaft 233. When the grab bucket 232 is in the relaxed position, the telescopic cylinder drives the grab bucket 232 to rotate around the hinge shaft 233, causing the second end 2322 of the grab bucket 232 to move away from the seat and gradually approach the connecting arm 231, so that the grab bucket 232 is as close as possible to the connecting arm 231. During the process of the grabbing device completing the seat assembly and retraction, the grab bucket 232 can avoid the armrests of the seat, facilitating the smooth retraction of the grabbing device.

[0035] In one embodiment, a positioning post 234 is provided at the end of the connecting arm 231 away from the linear servo module 22, and a positioning hole 235 is provided at the first end 2321. The first end 2321 is inserted and engaged with the positioning post 234 through the positioning hole 235, and is fastened to the end of the connecting arm 231 away from the linear servo module 22 by fasteners.

[0036] It should be noted that a connecting plate is provided at the end of the connecting arm 231 away from the linear servo module 22, and a positioning post 234 is provided on the connecting plate. The first end 2321 of the gripping bucket 232 has a positioning hole 235 that matches the positioning post 234. The fasteners are bolts used in the prior art. Multiple matching screw holes are provided around the positioning post 234 on the connecting plate and around the positioning hole 235 on the first end 2321. The positioning post 234 of the connecting plate and the positioning hole 235 of the gripping bucket 232 are connected by plug-in to achieve quick positioning of the connecting plate and the gripping bucket 232. After plugging, the connecting plate and the first end 2321 are fastened to each other by multiple bolts passing through the multiple screw holes, so that the gripping bucket 232 is connected to the connecting arm 231, which facilitates the quick assembly and disassembly of the gripping bucket 232. The hinge shaft 233 is located on the side of the connecting plate away from the positioning post 234. The connecting plate and the grab bucket 232 can rotate together relative to the hinge shaft 233, so that the grab bucket 232 can rotate to avoid the armrest of the seat.

[0037] In one embodiment, the bucket is a C-shaped bucket, and a flexible contact strip 2323 is provided on the inner side of the second end 2322.

[0038] Please see Figure 4 The bucket is C-shaped, with the inner side of the bucket facing the seat. When the bucket is inserted into the gap of the seat, the flexible contact strip 2323 on the inner side of the second end 2322 abuts against the back of the seat when the lifting mechanism drives the grab bucket 232 to rise. This prevents the grab bucket 232 from damaging the seat and increases the friction between the grab bucket 232 and the seat, further ensuring that the grab bucket 232 firmly grips the seat.

[0039] In one embodiment, the flipping mechanism 10 includes a column 11, a drive gear 12, a driven gear 13, and a flipping drive member. One end of the column 11 is connected to the lifting mechanism, and the drive gear 12 is rotatably mounted on the other end of the column 11. The driven gear 13 meshes with the drive gear 12, and the shaft of the driven gear 13 is connected to the bracket 21. The flipping drive member can drive the drive gear 12 to rotate around a first horizontal direction, so as to drive the bracket 21 to rotate around the first horizontal direction through the driven gear 13.

[0040] Explained in detail, the flipping drive unit drives the driving gear 12 to rotate around the first horizontal direction. The driving gear 12, through meshing, drives the driven gear 13 to rotate in the same direction. The shaft of the driven gear 13 transmits the rotation to the bracket 21, causing the bracket 21 and the gripping assembly 23 mounted on it to rotate synchronously around the first horizontal direction, thereby allowing the gripping assembly 23 to rotate between the gripping position and the releasing position. The power transmission of the flipping drive unit is achieved through the meshing of the driving gear 12 and the driven gear 13, ensuring precise control of the rotation angle of the gripping assembly 23 and significantly improving the gripping accuracy of the gripping device.

[0041] In one embodiment, the flipping drive is a servo motor, and the flipping mechanism 10 also includes a reducer and a brake. The output shaft of the servo motor is connected to the drive gear 12 through the reducer to drive the drive gear 12 to rotate in the first horizontal direction. The brake is connected to the output shaft to brake the drive gear 12 through the output shaft.

[0042] Furthermore, the tilting drive uses a servo motor. The output shaft of the servo motor is connected to the input shaft of the reducer via a coupling. The output shaft of the reducer is connected to the drive gear 12. The torque output by the servo motor is amplified by the reducer and then output to the drive gear 12, thereby ensuring the stable rotation of the drive gear 12 under load conditions. When the drive gear 12 needs to stop rotating, the brake stops the output shaft by holding or clamping, thereby braking the drive gear 12 and preventing the gripping component 23 from shifting position due to inertia.

[0043] In one embodiment, one end of the column 11 is provided with a flange 15 for connection with the lifting mechanism, and a plurality of reinforcing ribs 16 spaced circumferentially along the flange 15 are connected between the flange 15 and the column 11.

[0044] Please see Figure 1 The flange 15 is bolted to the lifting mechanism to ensure a stable connection between the column 11 and the lifting mechanism. Multiple reinforcing ribs 16 connect the flange 15 and the column 11, distributed circumferentially along the flange 15 to form a uniform support structure. When the lifting mechanism moves the column 11 up or down, the flange 15 and the reinforcing ribs 16 can jointly withstand the torque and bending moment generated by the tilting drive of the tilting mechanism 10, further improving the reliability of the connection between the column 11 and the lifting mechanism.

[0045] In one embodiment, a limiting mechanism 30 is provided between any two adjacent gripping components 23. The limiting mechanism 30 is used on both sides along the first horizontal direction to limit the two seats gripped by the two gripping components 23.

[0046] Please see Figure 1When two adjacent gripping components 23 grip the two seats at the same time, the limiting structure can abut against the two seats on both sides along the first horizontal direction to prevent the two seats from shifting or shaking, ensuring that the seats can be accurately installed in the vehicle, thereby improving the gripping reliability of the gripping components 23 and the assembly accuracy of the seats.

[0047] In one embodiment, the limiting mechanism 30 includes two limiting plates 31 spaced apart along a first horizontal direction, and the two limiting plates 31 can respectively abut and limit the two seats grasped by the two gripping components 23.

[0048] Furthermore, during the seat gripping process, when two adjacent gripping components 23 grip two adjacent seats respectively, each limiting plate 31 can abut against the side of the seat on the same side, forming a stable limiting support. The setting of the limiting plate 31 ensures that the relative position of the two seats in the horizontal direction is fixed, preventing displacement or shaking caused by external forces or their own weight, thereby improving the stability of seat gripping. The installation position and angle of the limiting plate 31 can be adjusted according to the spacing and shape of the seats to adapt to the seat assembly requirements of different vehicle models.

[0049] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
