Description

Technical Field

[0001] This utility model relates to the field of automotive interior accessories technology, specifically a segmented elastic connecting strip for fixing automotive seat covers. Background Technology

[0002] Car seat covers are the "outer garment" of car seats, not only giving the seats an aesthetically pleasing appearance, but also directly affecting the tactile feel and riding experience of drivers and passengers. They are made of a variety of materials, including fabric, leather, and artificial leather. Fabric covers are breathable and affordable, while leather and artificial leather covers have a high-end feel and are easy to clean. In addition to basic decorative and tactile functions, seat covers also need to have properties such as wear resistance, flame retardancy, and stain resistance to meet the complex needs of car use. Elastic bands, as a new type of auxiliary fixing material, are gradually emerging in the fixing of car seat covers. Elastic bands are made of elastic fibers blended or woven with other materials. They have the characteristics of high elasticity and strong flexibility. When the seat cover is subjected to external force, it can absorb and disperse stress through its own elastic deformation, ensuring that the cover always maintains a good fit with the seat. Even if the seat has functions such as lumbar support and massage, when the air bag is inflated, the elastic band can also stretch elastically to make the cover adapt to the changes in the seat surface, avoiding separation, wrinkles or damage. As interior components that come into direct contact with drivers and passengers, the fixation of car seat covers not only affects the riding experience but also the product's durability and safety. Traditional seat cover fixing methods often use non-adjustable fixed connecting straps or simple buckle structures. Fixed connecting straps cannot be adapted to different car models or seat covers of different sizes, which makes it difficult to apply the same connecting strap to a variety of products, thus limiting production versatility and market adaptability. Therefore, a segmented elastic connecting strap for fixing car seat covers is proposed to address the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a segmented elastic connecting strap for fixing car seat covers, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A segmented elastic connecting strap for fixing a car seat cover includes a connecting frame, an elastic connecting strap body installed inside the connecting frame, and a length adjustment mechanism provided inside the connecting frame.

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.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0016] Please see Figures 1-6 This utility model provides a technical solution: A segmented elastic connecting strap for fixing a car seat cover includes a connecting frame 1, an elastic connecting strap body 2 installed inside the connecting frame 1, and a length adjustment mechanism 3 provided inside the connecting frame 1. The length adjustment mechanism 3 includes a rotating seat 31, a rotating shaft 32 is rotatably engaged inside the rotating seat 31, a rotating cover 33 is fixedly connected to the top of the rotating shaft 32, a rotating plate 34 is fixedly connected to the top of the rotating cover 33, a positioning rod 35 is engaged inside the end of the rotating plate 34 away from the rotating cover 33, a connecting plate 36 is fixedly connected to the top of the positioning rod 35, a pull ring 37 is fixedly connected to the top of the connecting plate 36, a compression spring 38 is provided between the connecting plate 36 and the rotating plate 34, and a positioning hole 39 is provided on the top of the connecting frame 1.

[0017] Furthermore: the interior of the connecting frame 1 is hollow, and the inner walls on both sides of the connecting frame 1 are provided with moving grooves 11. The elastic connecting belt body 2 is movably connected to the interior of the connecting frame 1 through the moving grooves 11. The rotating seat 31 is fixed and symmetrically connected to the top of the connecting frame 1. The rotating shaft 32 is rotatably engaged with the interior of the connecting frame 1 through the rotating seat 31. The elastic connecting belt body 2 is wrapped around the outside of the rotating shaft 32. The rotating cover 33 and the rotating plate 34 are rotatably connected to the top of the rotating seat 31. The connecting plate 36 and the pulling ring 37 are located above the rotating plate 34. The compression spring 38 is fixedly connected to the outside of the positioning rod 35, and the positioning rod 35 is movably connected to the interior of the rotating plate 34 through the compression spring 38. The bottom of the positioning rod 35 is adapted to the positioning hole 39.

[0018] It should be noted that: the connecting frame 1 serves as the main support structure, with a hollow interior and movable grooves 11 on both sides. The elastic connecting strap body 2 moves within the connecting frame 1 through the movable grooves, which not only limits the range of movement of the elastic connecting strap 2 but also provides space for its extension or length adjustment. The elastic connecting strap body 2 is the component that directly contacts the seat cover, using its own elasticity to adapt to different sizes of covers, while achieving segmented fixation through the connecting frame 1.

[0019] Specifically: Under the elastic force of the compression spring 38, the bottom of the positioning rod 35 at the end of the rotating plate 34 is inserted into the positioning hole 39 at the top of the connecting frame 1, restricting the rotation of the rotating plate 34 and the rotating shaft 32. If it is necessary to adjust the elastic connecting belt body 2, the connecting plate 36 is lifted by pulling the ring 37, which drives the positioning rod 35 to disengage from the positioning hole 3. At this time, the length can be freely adjusted by rotating the plate 34. After releasing the ring 37, the compression spring 38 returns to its original position, and the positioning rod 35 is re-inserted into the positioning hole 39 to complete the fixation.

[0020] As a further implementation of this solution, the connecting frame 1 is provided with a clamping anti-wear mechanism 4. The clamping anti-wear mechanism 4 includes a movable rod 41. A stabilizing plate 42 is fixedly connected to the outside of the movable rod 41. A rubber pad 43 is installed on the outer surface of the stabilizing plate 42. A buffer spring 44 is sleeved on the movable rod 41.

[0021] Furthermore: the movable rod 41 is symmetrically and movably engaged in the inner wall of the connecting frame 1, the stabilizing plate 42 and the rubber pad 43 are movably connected inside the connecting frame 1 by the shock-absorbing spring 44, and the stabilizing plate 42 and the rubber pad 43 are located on both sides of the moving groove 11.

[0022] It should be noted that: the buffer spring 44 is sleeved on the movable rod 41. When the elastic connecting belt body 2 is stretched or subjected to force, the stabilizing plate 42 always fits against the elastic connecting belt body 2 under the action of the spring force 44, so as to avoid the connecting belt shaking and rubbing against the inner wall of the connecting frame 1, which would cause wear. The rubber pad 43 increases the friction with the elastic connecting belt body 2 on the one hand, improving the fixing effect, and on the other hand, reduces the hard contact between the elastic connecting belt body 2 and the stabilizing plate 42 through its own elasticity, while avoiding the connecting belt rubbing against the seat cover and causing scratches.

[0023] Workflow: When adjusting the length of the elastic connecting strip body 2, first pull the pull ring 37 upwards by hand. The pull ring 37 moves the connecting plate 36 upwards, causing the positioning rod 35 to overcome the elastic force of the compression spring 38 and disengage from the positioning hole 39 at the top of the connecting frame 1. At this time, the rotating plate 34 is no longer restricted by the positioning rod 35. With the rotating shaft 32 inside the rotating seat 31 as the axis, the rotating cover 33 drives the rotating shaft 32 to rotate. During the rotation of the rotating shaft 32, the elastic connecting strip body 2 wrapped around its outer side is wound or unwound accordingly. If the rotating plate 34 is rotated clockwise, the elastic connecting strip body 2 will be wound or unwound. Body 2 will wrap more around the rotating shaft 32, shortening the length of the elastic connecting strap body 2 extending out of the connecting frame 1; if the rotating plate 34 is rotated counterclockwise, the elastic connecting strap body 2 will loosen on the rotating shaft 32, increasing the length extending out of the connecting frame 1. After the elastic connecting strap body 2 is adjusted to the appropriate length, the pull ring 37 is released. Under the elastic force of the compression spring 38, the positioning rod 35 moves downward and re-engages into the corresponding positioning hole 39 at the top of the connecting frame 1, fixing the rotating plate 34 in the current position. This achieves precise adjustment and fixation of the length of the elastic connecting strap body 2 to adapt to the fixing requirements of different car seat covers. During the use of the car seat, when the elastic connecting strip body 2 is subjected to stretching or contraction force, it will slide in the moving groove 11 inside the connecting frame 1. At this time, the clamping anti-wear mechanism 4 plays a role. Under the pressure of the elastic connecting strip body 2, the movable rod 41 can move slightly in the inner wall of the connecting frame 1. The stabilizing plate 42 on the outside of the movable rod 41 and the rubber pad 43 on the outside of the stabilizing plate 42 are closely attached to both sides of the elastic connecting strip body 2. The rubber pad 43 is soft in texture, which can increase the friction between it and the elastic connecting strip body 2, prevent it from sliding freely in the moving groove 11, and avoid wear on the surface of the elastic connecting strip body 2 due to direct friction. When the seat is subjected to external impact or structural changes due to functional changes, the external force on the elastic connecting strip body 2 will be transmitted to the movable rod 41. At this time, the buffer spring 44 on the movable rod 41 will undergo compression or stretching deformation to absorb and buffer the external force, reduce the impact of the external force on the elastic connecting strip body 2 and the car seat cover, ensure the stability and reliability of the connection between the elastic connecting strip body 2 and the seat cover, and extend the service life of both. In practical applications, the connecting frame 1 serves as the basic frame. Its hollow interior and the movable grooves 11 on both inner walls provide a smooth movement channel for the elastic connecting strap body 2. The length adjustment mechanism 3 enables flexible adjustment of the length of the elastic connecting strap body 2, ensuring that it can adapt to car seat covers of different sizes and shapes. The clamping and anti-wear mechanism 4 ensures the stable fixation and reduces wear of the elastic connecting strap body 2 during daily use. The three work together. When the shape of the car seat changes due to passenger seating, seat function adjustments, etc., the length adjustment mechanism 3 can pre-adjust the length of the elastic connecting strap body 2. During use, the clamping and anti-wear mechanism 4 plays a real-time role, keeping the elastic connecting strap body 2 in a good fixed state at all times, while avoiding unnecessary friction and damage between it and the seat cover, thus completing the fixation work of the car seat cover efficiently and reliably.
