Description

Technical Field

[0001] This utility model relates to the field of automotive interior accessories technology, specifically to a pre-embedded stress dispersion structure for fixing fabric strips of automotive seat covers. Background Technology

[0002] As a crucial component that comes into direct contact with drivers and passengers, the quality and performance of car seats directly affect the driving and riding experience. The seat cover fixing strip, as a key component connecting the seat cover and the foam pad, is of paramount importance in terms of its performance. Functionally, it mainly bears the important responsibility of fixing the seat cover, ensuring that the seat cover can stay in the correct position during the car's operation and daily use by the driver and passengers, without shifting or deforming, thus ensuring the aesthetics and comfort of the seat. Traditional connection methods mainly use sewing, gluing or simple buckles for fixing. During long-term car operation, the sewing thread is easily worn and broken due to the impact of bumps and vibrations, causing the cover to loosen and deform. Although the gluing method is simple to operate, it is easily affected by the complex environment such as high temperature and humidity inside the car, and the adhesive is prone to aging and failure, resulting in a significant decrease in connection strength. Because the fixing method cannot effectively distribute the stress borne by the fabric strip during use, the stress is concentrated in a local area, which not only shortens the service life of the fabric strip, but may also cause problems such as deformation and cracking of the seat cover, affecting the overall aesthetics and performance of the car interior. Therefore, a pre-embedded stress dispersion structure for fixing fabric strips of car seat covers is proposed to address the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a pre-embedded stress dispersion structure for fixing fabric strips of 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: An embedded stress dispersion structure for fixing fabric strips of car seat covers includes an embedded shell and a fabric strip body, wherein a clamping stress dispersion mechanism is provided inside the embedded shell. The clamping stress dispersion mechanism includes a first clamping plate, a pressure spring fixedly connected to the outer side of the first clamping plate, the end of the pressure spring away from the first clamping plate being fixedly connected to the inner wall of the pre-embedded housing, a snap-fit ​​rod fixedly connected to the side of the first clamping plate away from the pressure spring, a fixing rod fixedly connected to the inner wall of the pre-embedded housing, a second clamping plate fixedly connected to the outer side of the fixing rod, a positioning hole being provided inside the second clamping plate, and hook surfaces being provided on the outer sides of the first clamping plate and the second clamping plate.

[0005] As a further optimization of this utility model, the following features are provided: a movable groove is provided in the inner wall of one side of the pre-embedded housing; rough surfaces are fixedly connected to both sides of one end of the cloth strip body; the cloth strip body is installed inside the pre-embedded housing through the movable groove; a threaded pipe is fixedly connected to the outer side of the pre-embedded housing; a screw is threadedly connected to the inside of the threaded pipe; a rotating handle is fixedly connected to the outer side of the screw; and a push cover is fixedly connected to the end of the screw away from the rotating handle.

[0006] As a further optimization of this utility model, the following features are provided: an installation mechanism is provided on the outer side of the pre-embedded housing; the installation mechanism includes an installation plate; an expansion screw is provided inside the installation plate; a connecting plate is fixedly connected to one end of the installation plate; a stabilizing plate is fixedly connected to the outer side of the connecting plate; a connecting column is rotatably connected inside the stabilizing plate; and a flange pipe is fixedly connected to the outer side of the pre-embedded housing.

[0007] As a further optimization of this utility model, the pressure springs are symmetrically distributed between the inner wall of the first clamping plate and the pre-embedded housing, and the first clamping plate and the second clamping plate have the same size.

[0008] As a further optimization of this utility model, the locking rods are symmetrically distributed at the four outer corners of the first clamping plate, the locking rods and the positioning holes are on the same plane, and the locking rods are adapted to the positioning holes.

[0009] As a further optimization of this utility model, the screw passes through the inner wall of the pre-embedded housing, and the push cover is movably connected to the outside of the No. 1 clamping plate via the screw.

[0010] As a further optimization of this utility model, the mounting plates are symmetrically distributed on the outside of the pre-embedded housing, the pre-embedded housing is located in the slots inside the two mounting plates, and the outside of the connecting column is provided with threads that are compatible with the threads inside the flange pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the No. 1 clamping plate, the pressure spring, and the No. 2 clamping plate in the stress dispersion mechanism cooperate with each other. The pressure spring is symmetrically distributed between the No. 1 clamping plate and the inner wall of the pre-embedded housing. When the fabric strip body is subjected to force, the pressure spring can absorb part of the stress. At the same time, the No. 1 clamping plate and the No. 2 clamping plate can evenly disperse the stress by cooperating with the hook surface and the rough surface of the fabric strip body, as well as by matching the snap rod with the positioning hole. This avoids excessive local stress on the fabric strip body, improves the stability and reliability of the car seat cover fixing, and extends the service life of the fabric strip and related components.

[0016] Please see Figures 1-6 This utility model provides a technical solution: An embedded stress dispersion structure for fixing fabric strips of car seat covers includes an embedded shell 1 and a fabric strip body 2, wherein a clamping stress dispersion mechanism 3 is provided inside the embedded shell 1. The clamping stress dispersion mechanism 3 includes a first clamping plate 36, a pressure spring 35 fixedly connected to the outer side of the first clamping plate 36, the end of the pressure spring 35 away from the first clamping plate 36 fixedly connected to the inner wall of the pre-embedded housing 1, a snap-fit ​​rod 37 fixedly connected to the side of the first clamping plate 36 away from the pressure spring 35, a fixing rod 38 fixedly connected to the inner wall of the pre-embedded housing 1, a second clamping plate 39 fixedly connected to the outer side of the fixing rod 38, a positioning hole 310 opened inside the second clamping plate 39, and hook surfaces 311 provided on the outer sides of the first clamping plate 36 and the second clamping plate 39.

[0017] It should be noted that: a movable groove 11 is provided in the inner wall of one side of the pre-embedded housing 1, and a rough surface 21 is fixedly connected to both sides of one end of the cloth strip body 2. The cloth strip body 2 is installed inside the pre-embedded housing 1 through the movable groove 11. A threaded tube 31 is fixedly connected to the outer side of the pre-embedded housing 1. A screw 32 is threadedly connected inside the threaded tube 31. A rotating handle 33 is fixedly connected to the outer side of the screw 32. A push cover 34 is fixedly connected to the end of the screw 32 away from the rotating handle 33.

[0018] Furthermore: the pressure springs 35 are symmetrically distributed between the first clamping plate 36 and the inner wall of the pre-embedded housing 1. The first clamping plate 36 and the second clamping plate 39 are the same size. The locking rods 37 are symmetrically distributed at the four outer corners of the first clamping plate 36. The locking rods 37 and the positioning holes 310 are on the same plane and are compatible with each other. The screw 32 passes through the inner wall of the pre-embedded housing 1. The push cover 34 is movably connected to the outside of the first clamping plate 36 through the screw 32.

[0019] Specifically: the pre-embedded housing 1 is the basic load-bearing component of the entire structure. The interior provides installation space for the cloth strip body 2. The cloth strip body 2 is initially fixed by cooperating with the hook surface 311 of the clamping stress dispersion mechanism 3 through the rough surfaces 21 on both sides. At the same time, it passes through the moving groove 11 into the pre-embedded housing 1 for easy position adjustment.

[0020] As a further implementation of this scheme, an installation mechanism 4 is provided on the outside of the pre-embedded housing 1. The installation mechanism 4 includes an installation plate 41, an expansion bolt 42 is provided inside the installation plate 41, a connecting plate 43 is fixedly connected between one end of the installation plate 41, a stabilizing plate 44 is fixedly connected to the outside of the connecting plate 43, a connecting column 45 is rotatably connected inside the stabilizing plate 44, and a flange pipe 46 is fixedly connected to the outside of the pre-embedded housing 1.

[0021] It should be noted that: the mounting plates 41 are symmetrically distributed on the outside of the pre-embedded housing 1, the pre-embedded housing 1 is located in the slots inside the two mounting plates 41, the outer side of the connecting column 45 is provided with threads, and the threads are compatible with the threads inside the flange pipe 46.

[0022] Furthermore: the connection between the mounting plate 41 and the expansion screw 42 is achieved by fixing the mounting plate 41 to the seat frame with the expansion screw 42, providing a basic mounting point. The connection between the connecting column 45 and the flange pipe 46 is achieved by threaded connection to fix the embedded housing 1 to the mounting mechanism 4. The stabilizing plate 44 and the connecting plate 43 can enhance the overall rigidity of the mounting mechanism 4 and prevent loosening due to vibration after installation.

[0023] Workflow: When installing the cloth strip body 2, the movable groove 11 on one side of the inner wall of the pre-embedded housing 1 is used to insert the end of the cloth strip body 2 with the rough surface 21 into the interior of the pre-embedded housing 1 along the movable groove 11. The rough surface 21 forms a Velcro-like fit with the hook surface 311 on the outer side of the first clamping plate 36 and the second clamping plate 39, initially fixing the position of the cloth strip body 2. Then, the screw 32 is rotated by rotating the handle 33. Since the screw 32 is threadedly connected to the threaded tube 31, the screw 32 will make linear motion in the threaded tube 31 while rotating, thereby pushing the push cover 34 to move towards the first clamping plate 36. The push cover 34 squeezes the first clamping plate. 36, so that it overcomes the elastic force of the pressure spring 35 and moves closer to the second clamping plate 39. At this time, the snap-fit ​​rods 37 symmetrically distributed at the four corners of the outer side of the first clamping plate 36 will accurately insert into the corresponding positioning holes 310 inside the second clamping plate 39, so as to achieve precise positioning and stable snap-fit ​​between the first clamping plate 36 and the second clamping plate 39. As the first clamping plate 36 and the second clamping plate 39 gradually close, the hook surface 311 on the outer side of the two and the rough surface 21 of the cloth strip body 2 are tightly attached to form a strong clamping force, which stably fixes the cloth strip body 2 inside the pre-embedded housing 1. And by adjusting the rotation degree of the screw 32, it can adapt to cloth strip bodies 2 of different thicknesses and specifications. When the car seat cover is pulled by an external force, the force is first applied to the fabric strip body 2. Since the fabric strip body 2 is firmly clamped by the first clamping plate 36 and the second clamping plate 39, the external force is transmitted to the first clamping plate 36 and the second clamping plate 39. At this time, the pressure springs 35, which are symmetrically distributed between the first clamping plate 36 and the inner wall of the pre-embedded housing 1, play a key role. The pressure springs 35 have elastic deformation characteristics and will be compressed under the action of external force. They absorb part of the stress through their own elastic deformation, converting the pulling force into the elastic potential energy of the spring, thereby alleviating the direct force of the external force on the fabric strip body 2. In response to impact, the No. 1 clamping plate 36 and the No. 2 clamping plate 39, as the main components for stress transmission, ensure that they can move synchronously when subjected to force through the cooperation of the snap-fit ​​rod 37 and the positioning hole 310, so that the stress is evenly distributed to the entire clamping surface. The large-area contact between the hook surface 311 of the No. 1 clamping plate 36 and the No. 2 clamping plate 39 and the rough surface 21 of the cloth strip body 2 also allows the stress to be more widely distributed in the contact area, avoiding excessive local stress on the cloth strip body 2, effectively preventing the cloth strip body 2 from breaking due to stress concentration, and improving the reliability and durability of the car seat cover fixing structure. When installing the pre-embedded stress dispersion structure, the pre-embedded housing 1 is first fixed to the corresponding position of the car seat by the installation mechanism 4. Specifically, the expansion screws 42 on the mounting plate 41 are aligned with the preset mounting holes of the car seat, and the expansion screws 42 are tightened to make them expand and tightly embed into the seat, thereby firmly fixing the mounting plate 41. Since the mounting plates 41 are symmetrically distributed on the outside of the pre-embedded housing 1, and the pre-embedded housing 1 is located in the slots inside the two mounting plates 41, the accuracy and stability of the installation position of the pre-embedded housing 1 are ensured. Subsequently, the connecting column 45 inside the stabilizing plate 44 is threadedly connected to the flange tube 46 on the outside of the pre-embedded housing 1 to further reinforce the pre-embedded housing 1. The connecting column 45 is rotated so that its thread is tightly engaged with the internal thread of the flange tube 46, thus achieving a stable installation of the pre-embedded housing 1 and ensuring that it will not loosen or fall off due to vibration or other factors during the use of the car seat.
