Description

Technical Field

[0001] This utility model relates to the field of automotive headrest technology, specifically to an auxiliary device for automotive headrest production. Background Technology

[0002] In the automotive manufacturing industry, car headrests are important safety and comfort components, and their production process involves multiple stages. Among them, the temporary placement and transfer of semi-finished headrests is one of the key factors affecting production efficiency and product quality. During the production of car headrests, semi-finished headrests usually need to be temporarily stored and transferred. For example, an auxiliary device for processing car headrests disclosed in a Chinese authorized patent (publication number: CN202122671506.3) includes a frame and a carrying plate. This device separates two adjacent headrests with two strip baffles to avoid confusion.

[0003] In existing automotive headrest storage racks, the headrests are separated by strip-shaped baffles at a fixed angle during use. However, this method cannot match headrest semi-finished products with different curvatures. In particular, irregularly shaped headrests formed by PIP process (such as curved designs with cutouts on the top) are prone to misfitting support, increasing the risk of slippage. The mismatch in shape between the headrest and the baffle leads to uneven stress, which may cause the headrest to shift or fall off during stacking and transportation. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary device for the production of automotive headrests. By setting an adjustable limiting part to limit the headrest, the problem of headrest slippage caused by non-fitting support is solved.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is an auxiliary device for automobile headrest production, including a frame and a limiting part. A bearing plate is installed in the frame, and a row of clearance grooves is opened on the bearing plate. Multiple sets of limiting parts are fitted in the row of clearance grooves. Each set of limiting parts has a first stop and a second stop. A crossbar is provided at the bottom of each first stop and second stop. A damping shaft and a connecting shaft are respectively connected to the end of each crossbar. A pulley is sleeved on each of the two connecting shafts, and a belt is fitted on the two pulleys.

[0007] Furthermore, the two ends of the crossbar are fitted onto the sides of the relief groove, and the bottoms of the first and second blocks are both located within the corresponding relief grooves.

[0008] Furthermore, the bearing plate has through holes and perforations, both of which are connected to the relief groove. The damping shaft fits into the perforation, and the connecting shaft fits into the through hole.

[0009] Furthermore, an L-shaped rod is installed at the end of the connecting shaft.

[0010] Furthermore, both the first and second blocks have convex grooves, and convex blocks slide within the convex grooves. Anti-slip pads are installed on the outer surface of the convex blocks.

[0011] This utility model has the following beneficial effects:

[0012] This utility model limits the headrest by setting an adjustable limiting part. Through the rotation adjustment function, the angle between the adjacent first block and the second block can be flexibly changed according to the needs of different shaped headrests, so that it fits tightly against the headrest surface. This greatly improves the adaptability of the auxiliary device to the placement of different shaped headrests and meets the needs of diversified production of modern automotive headrests.

[0013] This invention protects the headrest by using convex blocks and anti-slip pads. When the first and second blocks fix the headrest, the two anti-slip pads on the first and second blocks protect the headrest and prevent excessive force during clamping. When the anti-slip pads wear out after prolonged use, the anti-slip pads can be pulled upwards to slide the convex blocks out of the convex grooves, allowing for replacement or repair. After replacement, the anti-slip pads can be slid into the convex grooves through the convex blocks. The replacement operation of the anti-slip pads is relatively simple and increases replacement efficiency.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] 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 protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: an auxiliary device for automobile headrest production, including a frame 1 and a limiting part 3. A support plate 2 is installed inside the frame 1. A row of clearance grooves 201 is opened on the support plate 2. Multiple sets of limiting parts 3 are fitted in the row of clearance grooves 201. Each set of limiting parts 3 is evenly arranged along the clearance groove 201. Each set of limiting parts 3 has a first stop 301 and a second stop 309. The first stop 301 and the second stop 309 are arranged cyclically on the support plate 2. A crossbar 307 is provided at the bottom of each first stop 301 and the second stop 309. The two ends of the crossbar 307 are fitted on both sides of the clearance groove 201. The bottoms of the first stop 301 and the second stop 309 are located in the corresponding clearance groove 201. A damping rotating shaft 30 is connected to the end of each crossbar 307. 2. A connecting shaft 303 is connected to two pulleys 304, and a belt 305 is fitted onto each pulley 304. When the headrest is placed, the L-shaped rod 306 is rotated according to the shape of the headrest, causing the connecting shaft 303 to rotate, which in turn causes the pulleys 304 to rotate. Since the two pulleys 304 are driven by the belt 305, the rotation of the connecting shaft 303 can drive the two adjacent first stops 301 to rotate in the same direction. Then, the L-shaped rod 306 at the bottom of the second stop 309 is rotated, causing the second stop 309 to drive the two adjacent second stops 309 to rotate in the same direction. This changes the angle between the adjacent first stops 301 and second stops 309, allowing the device to rotate and adjust the first stops 301 and second stops 309 according to the arc shape of the headrest.

[0022] The support plate 2 has a through hole 202 and a through hole 203. Both the through hole 202 and the through hole 203 are connected to the relief groove 201. The damping shaft 302 is fitted in the through hole 203, and the connecting shaft 303 is fitted in the through hole 202. After the first stop 301 and the second stop 309 are rotated, the damping shaft 302 is in the through hole 203, so that the first stop 301 and the second stop 309 can maintain their positions to limit the headrest after rotation. An L-shaped rod 306 is installed at the end of the connecting shaft 303. The first stop 301 and the second stop 309 can be easily adjusted by the L-shaped rod 306.

[0023] Both the first stop 301 and the second stop 309 have convex grooves 308. A convex block 4 slides within the convex groove 308. An anti-slip pad 5 is installed on the outer surface of the convex block 4. When the first stop 301 and the second stop 309 fix the headrest, the two anti-slip pads 5 on the first stop 301 and the second stop 309 can protect the headrest and prevent excessive force when clamping and limiting. When the anti-slip pad 5 wears out after long-term use, the anti-slip pad 5 can be pulled upwards to make the anti-slip pad 5 drive the convex block 4 out of the convex groove 308 to replace or repair the anti-slip pad 5. After that, the replaced anti-slip pad 5 can be slid into the convex groove 308 through the convex block 4.
