Description

Technical Field

[0001] This utility model relates to the field of automotive seat backrest panel assemblies, and more particularly to a lightweight composite structure for automotive seat backrest panel assemblies. Background Technology

[0002] Lightweight composite structures for automotive seat backrest assemblies typically refer to the use of one or more lightweight composite materials to manufacture the backrest panel. The main purpose of this design is to reduce overall weight while maintaining or improving seat performance, thus offering several significant advantages.

[0003] Existing technologies, such as the invention with publication number CN106274590A, disclose a novel lightweight car seat frame. This patent includes an inverted "U"-shaped main steel tube for the backrest made of aluminum alloy composite material. Aluminum alloy side support wires are fixed to the two ends of the main steel tube via high-strength steel backrest connecting brackets. The upper ends of the main steel tube are connected to concave-convex aluminum alloy support wires on both sides. Based on a thorough understanding and application of the mechanical principles of car seats, this invention uses aluminum alloy instead of metal, significantly reducing the weight of the seat back frame while meeting the same strength requirements. Furthermore, aluminum alloy is more corrosion-resistant than metal, thus extending its service life, simplifying the structure and process, and reducing production cycle and cost.

[0004] The inventors discovered during use that the structure of lightweight composite materials in the prior art is often more complex than that of traditional materials. Some new composite materials may require specific processes and equipment for installation, which may make the installation process cumbersome and prolong the installation time. Moreover, new materials cannot be welded, and the use of adhesives is prone to cracking and difficult to repair. Utility Model Content

[0007] The effect achieved by the above components is as follows: when the back panel body needs to be installed, the back panel body is pulled to move, and then the back panel body drives the positioning rod and auxiliary block to move, and then the back panel body is installed on the frame. After moving to the appropriate position, the auxiliary block is pulled out from inside the positioning rod, and then the auxiliary block is locked and fixed to the frame. Then the connecting frame is pulled to move, and after moving to the appropriate position, the connecting frame drives the top rod to move. The top rod slides on the inner wall of the slide groove, and the top rod drives the spring to retract. After moving to the appropriate position, the spring stretches and drives the top rod to insert into the connecting frame for fixation.

[0008] Preferably, the end of the push rod away from the spring is fixedly connected to a connector, and the cross-section of the connector is semi-circular.

[0012] Preferably, an anti-slip pad, which is a rubber pad, is fixedly connected to the side of the auxiliary block near the frame.

[0013] The effect achieved by the above components is that the anti-slip pad can increase the friction between the auxiliary block and the frame, and prevent the auxiliary block from sliding when it is connected and positioned with the frame.

[0014] Preferably, the base has an auxiliary structure inside, which includes two connecting rings mounted on the base. A fixing plate is fixedly connected to the side of the connecting rings away from the base. A rotating rod is fixedly connected to the upper surface of the fixing plate.

Then the threaded tube is rotated to move, the threaded tube rotates on the rotating rod, the threaded tube drives the screw to move, the screw drives the fixing frame to move, the fixing frame drives the insert block to move, and then the insert block drives the back panel body to tighten, thereby facilitating the tightening of the back panel body.

[0016] Preferably, the arc surface of the threaded tube is provided with a plurality of slots, and the plurality of slots are evenly distributed on the threaded tube.

[0017] The effect achieved by the above components is that the groove can increase the friction between the hand and the threaded tube, preventing slippage when rotating the threaded tube.

[0018] Preferably, an anti-slip sleeve is fixedly connected to the inner wall of the back plate body, and the cross-section of the anti-slip sleeve is a hollow rectangle.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] Please see Figures 1 to 7The present invention provides a lightweight composite structure for an automotive seat backrest panel assembly, comprising: a base 1, a frame 2 mounted on the upper surface of the base 1, an mounting structure 3 on the surface of the frame 2, and an auxiliary structure 4 inside the base 1.

[0034] In the embodiments of this utility model, please refer to Figures 2 to 5 The installation structure 3 includes a back plate body 302, which is slidably connected to the frame 2. A positioning rod 307 is fixedly connected to the inner wall of the back plate body 302. The positioning rod 307 is slidably connected to the connecting frame 301. An auxiliary block 308 is rotatably connected to the inner wall of the positioning rod 307. Damping is provided between the auxiliary block 308 and the positioning rod 307. Connecting grooves 303 are provided on both sides of the back plate body 302. A rotating shaft 306 is rotatably connected to the inner wall of the connecting groove 303. A connecting block 305 is fixedly connected to the arc surface of 6. A connecting frame 301 is fixedly connected to the end of the connecting block 305 away from the rotating shaft 306. Several sliding grooves 310 are opened on the inner wall of the frame 2. The several sliding grooves 310 are evenly divided into two groups. A top rod 313 is slidably connected to the inner wall of the sliding groove 310. A spring 312 is set inside the sliding groove 310. The two ends of the spring 312 are fixedly connected to the top rod 313 and the sliding groove 310 respectively. The top rod 313 is slidably connected to the connecting frame 301. When the backplate body 302 needs to be installed, pull the backplate body 302 to move it. Then, the backplate body 302 drives the positioning rod 307 and the auxiliary block 308 to move. Then, the backplate body 302 is installed on the frame 2. After moving to the appropriate position, pull the auxiliary block 308 out from inside the positioning rod 307. Then, the auxiliary block 308 is locked and fixed to the frame 2. Then, pull the connecting frame 301 to move it. After moving to the appropriate position, the connecting frame 301 drives the top rod 313 to move. The top rod 313 slides on the inner wall of the slide groove 310. The top rod 313 drives the spring 312 to retract. After moving to the appropriate position, the spring 312 stretches and drives the top rod 313 to insert into the connecting frame 301 for fixation. The end of the top rod 313 away from the spring 312 is fixedly connected to the connector 304. The cross-section of the connector 304 is semi-circular. The connector 304 has a certain curvature to prevent the top rod 313 from getting stuck during retraction. A limit rod 311 is fixedly connected inside the slide groove 310, and the limit rod 311 is slidably connected to the top rod 313. A spring 312 is fitted onto the arc surface of the limit rod 311. The limit rod 311 limits the spring 312, preventing deformation during use and improving its service life. An anti-slip pad 309, made of rubber, is fixedly connected to the side of the auxiliary block 308 closest to the frame 2. The anti-slip pad 309 increases the friction between the auxiliary block 308 and the frame 2, preventing slippage during connection and positioning.

[0035] In the embodiments of this utility model, please refer to Figure 6 and Figure 7 The auxiliary structure 4 includes two connecting rings 41, which are mounted on the base 1. A fixing plate 42 is fixedly connected to the side of the connecting rings 41 away from the base 1. A rotating rod 43 is fixedly connected to the upper surface of the fixing plate 42. A threaded tube 46 is rotatably connected to the upper end of the rotating rod 43. A screw 44 is threadedly connected to the inner wall of the threaded tube 46. A fixing frame 45 is fixedly connected to the end of the screw 44 away from the threaded tube 46. Two inserts 48 are fixedly connected to the side of the fixing frame 45 near the back plate body 302. The inserts 48 are slidably connected to the back plate body 302. When further securing the backplate body 302 is required, the fixing frame 45 is pulled to move, causing the insert block 48 to move as well. The insert block 48 is then inserted into the backplate body 302. The threaded tube 46 is then rotated, moving on the rotating rod 43. This rotation causes the screw 44 to move, which in turn moves the fixing frame 45. The fixing frame 45 then moves the insert block 48, which in turn tightens the backplate body 302. The threaded tube 46 has several slots 47 evenly distributed on its arc surface. These slots increase friction between the hand and the threaded tube 46, preventing slippage during rotation. An anti-slip sleeve 49 is fixedly connected to the inner wall of the backplate body 302; the anti-slip sleeve 49 has a hollow rectangular cross-section. The anti-slip sleeve 49 can increase the friction between the insert 48 and the back plate body 302, and prevent the insert 48 from becoming loose when connected to the back plate body 302;

[0036] The working principle of the lightweight composite structure of the car seat backrest panel assembly provided by this utility model is as follows: When the backrest panel body 302 needs to be installed, pull the backrest panel body 302 to move it. Then, the backrest panel body 302 drives the positioning rod 307 and the auxiliary block 308 to move. Then, the backrest panel body 302 is installed on the frame 2. After moving to the appropriate position, pull the auxiliary block 308 out from inside the positioning rod 307. Then, the auxiliary block 308 is locked and fixed to the frame 2. Then, pull the connecting frame 301 to move it. After moving to the appropriate position, the connecting frame 301 drives the top rod 313 to move. 13 slides on the inner wall of the slide groove 310. The push rod 313 drives the spring 312 to retract. After moving to the appropriate position, the spring 312 is stretched, which drives the push rod 313 to insert into the connecting frame 301 for fixation. The limiting rod 311 can limit the spring 312 to prevent the spring 312 from deforming during use and improve the service life of the spring 312. The anti-slip pad 309 can increase the friction between the auxiliary block 308 and the frame 2 to prevent the auxiliary block 308 from sliding when it is connected and positioned with the frame 2. The connector 304 has a certain curvature to prevent the push rod 313 from getting stuck when it retracts.

[0037] When further securing the backplate body 302 is required, the fixing frame 45 is pulled to move, which in turn moves the insert block 48. The insert block 48 is then inserted into the backplate body 302. The threaded tube 46 is then rotated to move, rotating on the rotating rod 43. The threaded tube 46 moves the screw 44, which in turn moves the fixing frame 45. The fixing frame 45 moves the insert block 48, which then tightens the backplate body 302. This facilitates tightening the backplate body 302. The slot 47 increases the friction between the hand and the threaded tube 46, preventing slippage when rotating the threaded tube 46. The anti-slip sleeve 49 increases the friction between the insert block 48 and the backplate body 302, preventing loosening when the insert block 48 is connected to the backplate body 302.

[0038] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
