Description
Technical Field
[0001] This utility model belongs to the field of automotive interior technology, and in particular relates to an elastic band anti-rub strip. Background Technology
[0002] In automotive interior design, components with flip-up covers (such as storage box covers, glove box covers, etc.) widely use elastic bands as elastic elements to achieve automatic return of the cover and opening damping effect. The elastic band is usually fixed at both ends to the storage box body and connected to the flip mechanism in the middle, and will repeatedly stretch and contract during the opening and closing of the cover.
[0003] However, existing elastic band anti-scratch strips have certain defects. After the clamping plate is opened, a large area of the anti-scratch strip is exposed to the view, and the matching gap with the storage box is obvious and uneven, which seriously affects the overall aesthetics of the interior. In addition, this type of anti-scratch strip is made by injection molding, resulting in mold parting lines on the surface. Since elastic bands are mostly woven materials with uneven surfaces, the elastic bands rub against the parting lines during the stretching and contraction process, producing abnormal noise, which seriously affects the user experience. Utility Model Content
[0004] This utility model addresses certain shortcomings of existing elastic band anti-friction strips. The circular anti-friction strip is largely exposed after the clamping plate is opened, resulting in noticeable and uneven gaps between it and the storage box, severely impacting the overall aesthetics of the interior. Furthermore, this type of anti-friction strip is manufactured using injection molding, resulting in mold parting lines on the surface. Since elastic bands are mostly woven materials with uneven surfaces, friction between the elastic band and the parting lines during stretching and contraction produces abnormal noise, significantly affecting the user experience. The following technical solution is proposed: An elastic band anti-friction strip includes: Storage box for supporting elastic band anti-friction strips; Anti-scratch strip, connected to the storage box; An elastic band hole is provided inside the storage box; A roller shaft is connected to the storage box; A flip-plate assembly includes an inner cover of a clamping plate, an outer cover of a clamping plate, an elastic band, and a buffer pin. The inner cover of the clamping plate is movably disposed on the roller shaft, and the outer cover of the clamping plate is connected to the inner cover of the clamping plate. The elastic band is movably disposed on the inner cover of the clamping plate and is movably disposed in the elastic band hole. The buffer pin is disposed in the storage box and is located on the inner side of the inner cover of the clamping plate, and the buffer pin is kept in contact with the storage box. The outer cover of the clamping plate drives the inner cover of the clamping plate to rotate around the roller shaft.
[0005] Preferably, the inner cover of the clamping plate is provided with two elastic band holes, which are located at both ends of the inner cover of the clamping plate, and the elastic band is movably disposed in the elastic band holes.
[0006] Preferably, two anti-friction strips are provided on the storage box, and the anti-friction strips are respectively located at both ends of the storage box, with the elastic band kept in contact with the anti-friction strips.
[0007] Preferably, the anti-friction strip is provided with a circular protrusion, and the elastic band is kept in contact with the circular protrusion.
[0008] Preferably, the storage box is provided with an elastic band hook, and the elastic band is sleeved on the elastic band hook.
[0009] Preferably, the elastic band hook is located inside the elastic band hole, and the elastic band hook is provided in a one-to-one correspondence with the elastic band hole.
[0010] The beneficial effects of this utility model are as follows: The anti-friction strip can be installed by embedded welding, avoiding the problems of excessive exposure and obvious gaps in traditional designs. It can also completely separate the elastic band from the storage box, ensuring that the storage box will not be worn. It can also prevent the anti-friction strip parting line from rubbing against the elastic band and causing abnormal noise, thus significantly improving the user experience.

[0012] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0013] Example 1 This utility model provides an elastic band anti-rub strip, such as Figures 1 to 7 As shown, it includes: a storage box 1, an anti-friction strip 2, an elastic band hole 3, a roller shaft 4, and a flip-up assembly. The storage box 1 supports the elastic band anti-friction strip. The anti-friction strip 2 is connected to the storage box 1 and is welded and installed inside the storage box 1. The anti-friction strip 2 has a ring structure and a parting line. The area where the anti-friction strip 2 contacts the elastic band 7 adopts an open structure, optimizing the parting line position to ensure that the parting line of the anti-friction strip 2 avoids the area where the elastic band 7 contacts the anti-friction strip 2. The elastic band hole 3... The storage box 1 has two elastic band holes 3. A scuff strip 2 is embedded inside the storage box 1 (corresponding to the position of the elastic band hole 3). Two roller bearing shafts 4 are connected to the storage box 1. The flip-plate assembly includes an inner clamping plate cover 5, an outer clamping plate cover 6, an elastic band 7, and buffer pins 8. The inner clamping plate cover 5 is movably mounted on the roller bearing shafts 4. The two roller bearing shafts 4 are located at opposite ends of the inner clamping plate cover 5, and both ends of the inner clamping plate cover 5 rotate around the roller bearing shafts 4. The outer clamping plate cover 6 is connected to... The clamping plate inner cover 5 has an elastic band 7 movably mounted on it. The elastic band 7 is movably mounted in the elastic band hole 3. Two buffer pins 8 are mounted in the storage box 1, located inside the clamping plate inner cover 5 and pressed against the storage box 1. The clamping plate outer cover 6 drives the clamping plate inner cover 5 to rotate around the roller shaft 4. The clamping plate inner cover 5 has two elastic band holes 9 located at both ends of the clamping plate inner cover 5. The elastic band 7 is movably mounted in the storage box 1. An elastic band 7 is attached to the elastic band hole 29. A circular protrusion 10 is provided on the anti-friction strip 2. The elastic band 7 is kept in contact with the circular protrusion 10. An elastic band hook 11 is provided on the storage box 1. The elastic band 7 is sleeved on the elastic band hook 11. The elastic band hook 11 is located inside the elastic band hole 3. The elastic band hook 11 and the elastic band hole 3 are set one-to-one. There are two anti-friction strips 2 on the storage box 1. The anti-friction strips 2 are located at both ends of the storage box 1. The elastic band 7 is kept in contact with the anti-friction strip 2.
[0014] The anti-friction strip 2 can be embedded and welded together with the flip-plate assembly, avoiding the problems of excessive exposure and obvious gaps in traditional designs. It can also completely separate the elastic band 7 from the storage box 1, ensuring that the storage box 1 will not be worn. It can also prevent the anti-friction strip 2 parting line from rubbing against the elastic band 7 and causing abnormal noise, thus significantly improving the user experience.
[0015] In use, when the flip panel assembly is closed, the outer cover 6 of the clamping plate is flush with the storage box 1, forming a neat appearance. At this time, the elastic band 7 is in a natural or slightly stretched state. When the user needs to open the clamping plate to access items, the outer cover 6 of the clamping plate is pulled outward. The external force is transmitted through the outer cover 6 to the inner cover 5 of the clamping plate. Since the inner cover 5 of the clamping plate is movably connected to the roller shaft 4, it rotates around the roller shaft 4. As the clamping plate rotates around the roller shaft 4 and opens, the elastic band 7 (connected through the elastic band hole 2 9 and the elastic band hole 1 3) sleeved on the elastic band hook 11 is gradually stretched and extended. The stretched elastic band 7 generates an elastic restoring force, which always acts on the clamping plate, providing assistance for closing the clamping plate. Throughout the opening and closing process, the elastic band 7... The elastic band 7, which is in a retracting motion, will come into contact with and rub against the storage box 1. This device completely separates the elastic band 7 from the storage box 1 through a specially designed anti-friction strip 2. The anti-friction strip 2 can protect the storage box 1 from wear. The contact area between the anti-friction strip 2 and the elastic band 7 is designed with a circular protrusion 10. This protruding structure slightly lifts the elastic band 7. At the same time, the contact area between the anti-friction strip 2 and the elastic band 7 adopts an open structure, which can optimize the parting line position and ensure that the parting line of the anti-friction strip 2 avoids the contact area between the elastic band 7 and the anti-friction strip 2, preventing the elastic band 7 (with a rough surface) from directly rubbing against the parting line and producing abnormal noise. In addition, since a buffer pin 11 is provided on the inner cover 5 of the clamping plate, when the user releases and closes the clamping plate, the buffer pin 11 will abut against the surface of the storage box 1, effectively playing a role in buffering and limiting.
[0016] Specifically, both ends of the storage box 1 have elastic band holes 3. Anti-friction strips 2 are fixedly connected to the storage box 1 at the positions corresponding to the elastic band holes 3. Both ends of the storage box 1 have roller shafts 4. One end of the roller shaft 4 is movably connected to the inner cover of the clamping plate 5. One end of the inner cover of the clamping plate 5 is fixedly connected to the outer cover of the clamping plate 6. Both ends of the inner cover of the clamping plate 5 have elastic band holes 9. Both ends of the storage box 1 have elastic band hooks 11 fixedly connected to the inner side of the elastic band holes 3. Elastic bands 7 pass through and are connected to the elastic band holes 9 and 3. Elastic bands 7 are sleeved on the elastic band hooks 11. One end of the anti-friction strip 2 is fixedly connected to a circular protrusion 10. The outer surface of the elastic band 7 is in contact with the circular protrusion 10. One end of the inner cover of the clamping plate 5 is fixedly connected to a buffer pin 8. The buffer pin 8 is in contact with the storage box 1.
[0017] Working Principle: In actual use, when the flip-up assembly is closed, the outer cover 6 of the clamping plate is flush with the storage box 1, forming a neat appearance. At this time, the elastic band 7 is in a natural or slightly stretched state. When the user needs to open the clamping plate to access items, they pull the outer cover 6 of the clamping plate outward. The external force is transmitted through the outer cover 6 to the inner cover 5 of the clamping plate. Since the inner cover 5 of the clamping plate is movably connected to the roller shaft 4, it rotates around the roller shaft 4. As the clamping plate rotates around the roller shaft 4 and opens, the elastic band 7 (connected to the elastic band hole 2 9 and elastic band hole 1 3) sleeved on the elastic band hook 11 is gradually stretched and extended. The stretched elastic band 7 generates an elastic restoring force, which always acts on the clamping plate, providing assistance for closing the clamping plate. During the entire opening and closing process, the stretching elastic band 7 will come into contact and rub against the storage box 1. This device uses a specially designed anti-rub strip 2 to separate the elastic band 7 from the storage box 1. Completely separated, the anti-friction strip 2 protects the storage box 1 from wear and tear. The contact area between the anti-friction strip 2 and the elastic band 7 is designed with a circular protrusion 10. This protruding structure slightly lifts the elastic band 7. At the same time, the contact area between the anti-friction strip 2 and the elastic band 7 adopts an open structure, which can optimize the parting line position and ensure that the parting line of the anti-friction strip 2 avoids the contact area between the elastic band 7 and the anti-friction strip 2, preventing the elastic band 7 (with a rough surface) from directly rubbing against the parting line and causing abnormal noise. In addition, since a buffer pin 11 is provided on the inner cover 5 of the clamping plate, when the user releases and closes the clamping plate, the buffer pin 11 will abut against the surface of the storage box 1, effectively playing a role in buffering and limiting. The anti-friction strip 2 can be installed by embedded welding, avoiding the problems of excessive exposure and obvious gaps in traditional designs. It can also completely separate the elastic band 7 from the storage box 1, ensuring that the storage box 1 will not be worn, and can also prevent the friction between the parting line of the anti-friction strip 2 and the elastic band 7 from causing abnormal noise, thereby significantly improving the user experience.
[0018] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
