Description

Technical Field

[0001] This utility model relates to the field of automotive seat technology, specifically to a reinforcing component for the back of an electric seat. Background Technology

[0002] Electric seats are seat systems in automobiles (or some high-end furniture and medical equipment) that use motors to adjust the seat posture. Their core function is to replace traditional manual adjustments (such as wrenches and knobs) to meet the user's sitting posture needs in a more precise and convenient way, improving comfort and safety. Whether it is a car braking suddenly, cornering, or extreme collision scenarios, the seat back must withstand the impact force of the human body, and the back reinforcement component is an important part of safety protection.

[0003] In order to reduce design and manufacturing costs, some brands use a one-piece stamped back reinforcement frame for electric seat back reinforcement components. This makes it difficult to disassemble. If a part of the frame breaks, deforms, or rusts, the repair personnel can only replace the entire back reinforcement frame because the damaged part cannot be disassembled and repaired separately, which greatly increases the user's repair costs. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A power seat back reinforcement member includes:

[0006] The U-shaped frame has a pair of second through holes at both its left and right ends. A second fixing component is provided at both its left and right ends near the second through holes. The bottom of the pair of second fixing components is respectively connected to a first L-shaped frame and a second L-shaped frame. A pair of third through holes are provided at the top of the first L-shaped frame and the second L-shaped frame near the second fixing components.

[0007] The first L-shaped frame and the second L-shaped frame each have a pair of fifth through holes at their ends. A fourth fixing component is provided at the end of the first L-shaped frame and the second L-shaped frame near the fifth through holes. The internal structure of the fourth fixing component is the same as that of the second fixing component.

[0008] A pair of fourth through holes are provided at the middle position of the outer side of the first L-shaped frame and the second L-shaped frame. A third fixing component is fitted on the outer side of the first L-shaped frame and the second L-shaped frame near the fourth through holes. A T-shaped plate is fixedly connected at the middle position of the pair of third fixing components. A first fixing component is provided on the longer side of the T-shaped plate. The first fixing component is fitted on the outer side of the U-shaped frame. A pair of first through holes are provided at the middle position of the outer side of the U-shaped frame near the first fixing component. The internal structure of the first fixing component is the same as the internal structure of the third fixing component.

[0009] In one possible implementation, the interior of the second fixing component includes a cylinder, with a second fixing sleeve and a first fixing sleeve slidably connected to the upper and lower sides of the cylinder, respectively. The second fixing sleeve and the first fixing sleeve are respectively fitted onto the end of the U-shaped frame and the top of the first L-shaped frame. A pair of sixth through holes and a pair of seventh through holes are respectively opened on the sides of the second fixing sleeve and the first fixing sleeve. The position of the sixth through hole corresponds to the position of the second through hole, and the position of the seventh through hole corresponds to the position of the third through hole.

[0010] In one possible implementation, a partition is fixedly connected to the middle of the outer side of the cylinder, and the upper and lower ends of the cylinder extend into the interior of the U-shaped frame and the first L-shaped frame, respectively. A ninth through hole and an eighth through hole are respectively opened on the upper and lower sides of the cylinder. A first bolt connection pair is connected through the interior of the ninth through hole, a pair of second through holes and a pair of sixth through holes. A second bolt connection pair is connected through the interior of the eighth through hole, a pair of third through holes and a pair of seventh through holes.

[0011] In one possible implementation, the first fixing component includes a third fixing sleeve, which is fitted onto the outside of the U-shaped frame. The third fixing sleeve has tenth through holes on both its front and rear sides, and a third bolt connection pair is connected through the interior of both the tenth through holes and the first through hole.

[0012] In one possible implementation, the corner positions of the U-shaped frame, the first L-shaped frame, and the second L-shaped frame are all provided with rounded corner structures.

[0013] In one possible implementation, the inner side of the connection between the third fixing sleeve and the U-shaped frame is provided with an arc-shaped transition fillet, the radius of which is adapted to the fillet radius of the corresponding frame corner.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. By setting a pair of second fixing components at both ends of the U-shaped frame, the two ends of the U-shaped frame are connected to the first L-shaped frame and the second L-shaped frame respectively through a pair of second fixing components. The first L-shaped frame and the second L-shaped frame are fixedly connected by a fourth fixing component. The structures of the second fixing component and the fourth fixing component are identical. When it is necessary to disassemble the U-shaped frame and the first L-shaped frame, the first bolt connecting pair inserted into the end of the U-shaped frame and the second bolt connecting pair inserted into the top of the first L-shaped frame are removed by rotating, thereby separating the cylinder from the U-shaped frame and the first L-shaped frame. The cylinder can then be removed from the inside of the U-shaped frame and the first L-shaped frame, thus realizing the disassembly of the U-shaped frame and the first L-shaped frame. The operation steps are simple, greatly reducing maintenance costs and helping to avoid the problem of partial failure leading to the overall scrapping.

[0016] 2. By setting a T-shaped plate in the middle of the U-shaped frame, the first L-shaped frame, and the second L-shaped frame, the connection strength between the U-shaped frame, the first L-shaped frame, and the second L-shaped frame is further increased. At the same time, a third fixing component is set on the two shorter sides of the T-shaped plate, and a first fixing component is set on the longer side of the T-shaped plate. The internal structure of the first fixing component and the third fixing component is the same. When it is necessary to separate the T-shaped plate and the U-shaped frame, the third bolt connecting pair inserted into the U-shaped frame is removed by rotating, thereby separating the third fixing sleeve from the U-shaped frame, which makes it easy to remove the third fixing sleeve from the outside of the U-shaped frame.

[0025] This application provides a reinforcing member for the back of an electric seat, thereby solving the problems in the prior art.

[0026] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0027] like Figures 1-4 As shown, a reinforcing member for the back of an electric seat includes:

[0028] U-shaped frame 2, with a pair of second through holes 9 at both the left and right ends of U-shaped frame 2, and a second fixing component 3 at both the left and right ends of U-shaped frame 2 near the second through holes 9. The bottom of the pair of second fixing components 3 is respectively connected to a first L-shaped frame 4 and a second L-shaped frame 26, and the top of the first L-shaped frame 4 and the second L-shaped frame 26 near the second fixing component 3 are provided with a pair of third through holes 10.

[0029] The first L-shaped frame 4 and the second L-shaped frame 26 are each provided with a pair of fifth through holes 12 at their ends. The first L-shaped frame 4 and the second L-shaped frame 26 are provided with a fourth fixing component 6 near the fifth through holes 12 at their ends. The internal structure of the fourth fixing component 6 is the same as that of the second fixing component 3.

[0030] A pair of fourth through holes 11 are provided at the middle position of the outer side of the first L-shaped frame 4 and the second L-shaped frame 26. A third fixing component 5 is fitted on the outer side of the first L-shaped frame 4 and the second L-shaped frame 26 near the fourth through holes 11. A T-shaped plate 7 is fixedly connected at the middle position of the pair of third fixing components 5. A first fixing component 1 is provided on the longer side of the T-shaped plate 7. The first fixing component 1 is fitted on the outer side of the U-shaped frame 2. A pair of first through holes 8 are provided at the middle position of the outer side of the U-shaped frame 2 near the first fixing component 1. The internal structure of the first fixing component 1 is the same as the internal structure of the third fixing component 5.

[0031] In some examples, the interior of the second fixing component 3 includes a cylinder 14, with a second fixing sleeve 22 and a first fixing sleeve 21 slidably connected to the upper and lower sides of the cylinder 14, respectively. The second fixing sleeve 22 and the first fixing sleeve 21 are respectively fitted onto the end of the U-shaped frame 2 and the top of the first L-shaped frame 4. A pair of sixth through holes 13 and a pair of seventh through holes 18 are respectively opened on the sides of the second fixing sleeve 22 and the first fixing sleeve 21. The position of the sixth through hole 13 corresponds to the position of the second through hole 9, and the position of the seventh through hole 18 corresponds to the position of the third through hole 10.

[0032] In some examples, a partition 16 is fixedly connected to the middle of the outer side of the cylinder 14. The upper and lower ends of the cylinder 14 extend into the interior of the U-shaped frame 2 and the first L-shaped frame 4, respectively. The upper and lower sides of the cylinder 14 are respectively provided with a ninth through hole 20 and an eighth through hole 19. The interior of the ninth through hole 20, a pair of second through holes 9 and a pair of sixth through holes 13 are all connected by a first bolt connection pair 15. The interior of the eighth through hole 19, a pair of third through holes 10 and a pair of seventh through holes 18 are all connected by a second bolt connection pair 17. The first bolt connection pair 15 inserted into the end of the U-shaped frame 2 and the second bolt connection pair 17 inserted into the top of the first L-shaped frame 4 are removed, thereby separating the cylinder 14 from the U-shaped frame 2 and the first L-shaped frame 4, thereby removing the cylinder 14 from the interior of the U-shaped frame 2 and the first L-shaped frame 4, and thus realizing the disassembly of the U-shaped frame 2 and the first L-shaped frame 4.

[0033] In some examples, the first fixing component 1 includes a third fixing sleeve 25 inside. The third fixing sleeve 25 is fitted on the outside of the U-shaped frame 2. The front and rear sides of the third fixing sleeve 25 are provided with tenth through holes 24. The interior of the pair of tenth through holes 24 and the first through hole 8 are all connected by a third bolt connection pair 23. The third bolt connection pair 23 inserted into the U-shaped frame 2 is removed, thereby separating the third fixing sleeve 25 from the U-shaped frame 2, so that the third fixing sleeve 25 can be easily removed from the outside of the U-shaped frame 2.

[0034] In some examples, the corners of the U-shaped frame 2, the first L-shaped frame 4, and the second L-shaped frame 26 are all provided with rounded corner structures, which also facilitates the third fixing sleeve 25 to slide out from the outside of the first L-shaped frame 4.

[0035] In some examples, the inner side of the connection between the third fixing sleeve 25 and the U-shaped frame 2 is provided with an arc-shaped transition fillet. The radius of the arc-shaped transition fillet is adapted to the fillet radius of the corresponding frame corner, so as to facilitate the sliding of the third fixing sleeve 25 out from the outside of the U-shaped frame 2.

[0036] When the present invention requires the disassembly of the U-shaped frame 2 and the first L-shaped frame 4, the first bolt connecting part 15 inserted into the end of the U-shaped frame 2 and the second bolt connecting part 17 inserted into the top of the first L-shaped frame 4 are removed by rotation, thereby separating the cylinder 14 from the U-shaped frame 2 and the first L-shaped frame 4, and thus removing the cylinder 14 from the inside of the U-shaped frame 2 and the first L-shaped frame 4, thereby achieving the disassembly of the U-shaped frame 2 and the first L-shaped frame 4. When the T-shaped plate 7 and the U-shaped frame 2 need to be disassembled, the third bolt connecting part 23 inserted into the inside of the U-shaped frame 2 is removed by rotation, thereby separating the third fixing sleeve 25 from the U-shaped frame 2, thus facilitating the removal of the third fixing sleeve 25 from the outside of the U-shaped frame 2.

[0037] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
