Description

Technical Field

[0001] This utility model relates to the field of automotive door trim technology, specifically an automotive door trim. Background Technology

[0002] With the booming development of the automotive industry and the continuous improvement of consumers' demand for vehicle personalization, the design and functional optimization of automotive interior and exterior components have become the focus of industry attention. As an important decorative component of car doors, car door trim not only enhances the overall aesthetics of the vehicle, but also protects the edges of the door and reduces scratches and damage.

[0003] When existing car door trim is in use,

[0004] (1) Traditional car door trim strips are mostly one-piece designs with fixed styles, and cannot be flexibly changed according to the owner's preferences. If you want to change the door trim strips, you often need to disassemble the whole thing, which is complicated and can easily damage the car door.

[0005] (2) Most door trim strips are fixed with double-sided adhesive or simple clips. During long-term use, they are prone to loosening or even falling off due to factors such as temperature changes and vehicle vibration. This not only affects the appearance, but the fallen trim strips may also pose a safety hazard to driving.

[0006] To address the aforementioned problems, this utility model provides an automotive door trim strip. Utility Model Content

[0007] The purpose of this utility model is to provide an automotive door trim strip. This utility model achieves the effect of quick style replacement and firm installation of door trim strips through easily switchable trim strip components and sturdy fixing components, thereby solving the problems of existing door trim strips having limited styles and unstable installation.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a car door trim strip, including a fixed base plate, a switchable trim strip assembly fixedly connected to the middle of the top of the fixed base plate, and fixed components fixedly connected to both sides of the top of the fixed base plate. The switchable trim strip assembly includes a connecting plate fixedly connected to the middle of the top of the fixed base plate, and fixed plates fixedly connected to both sides of the surface of the connecting plate. A sliding rod is slidably connected to the inner wall of the fixed plate, and a control rod is fixedly connected to the surface of the sliding rod.

[0009] Furthermore, a return spring is fixedly connected to the surface of the sliding rod, and a clamping disc is fixedly connected to the bottom end of the sliding rod. This allows the sliding rod to be pulled up by the control rod to compress the return spring, causing the clamping disc to rise and facilitating the replacement of the trim strip. When the control rod is released, the return spring rebounds, and the clamping disc presses down to firmly clamp the trim strip, achieving the function of quick replacement and ensuring that the trim strip is installed securely.

[0010] Furthermore, a placement plate is slidably connected to the top of the connecting plate, and a control handle is fixedly connected to the surface of the placement plate. This allows the placement plate to be easily pulled and slid on the connecting plate using the control handle, facilitating precise adjustment of the trim position. Additionally, the placement plate can be pulled out when replacing the trim, making the operation more convenient.

[0011] Furthermore, the fixing component includes a fixing circular plate fixedly connected to both sides of the top of the fixing base plate. Four damping expansion joints are distributed in a ring on the back of the fixing circular plate. This achieves the effect of utilizing the expansion and buffering characteristics of the damping expansion joints to adapt to the unevenness of the car door surface, so that the fixing suction cup can fit tightly against the car door, while reducing the impact of vehicle driving vibration on the door trim and improving installation stability.

[0012] Furthermore, a fixed circular block is fixedly connected to the surface of the damping telescopic device, and a fixed suction cup is fixedly connected to the surface of the fixed circular block. This allows the door trim to be quickly installed and removed without tools by adhering to the surface of the car door through the fixed suction cup. The suction force is strong and can effectively prevent the door trim from loosening and falling off. At the same time, it seals the gap between the car door and the trim to prevent dust and water stains from entering.

[0013] Furthermore, connecting round blocks are fixedly connected to both sides of the top of the fixed round plate, and hanging ropes are fixedly connected to the surface of the connecting round blocks. This allows the door trim strip to be hung and stored after it is removed, saving space and making it easy to store and manage. When cleaning the vehicle, the door trim strip can also be temporarily fixed by the hanging ropes to prevent it from shaking.

[0014] Furthermore, the bottom surface of the clamping disc is provided with anti-slip protrusions, which are distributed in a hemispherical array and made of silicone material. This increases the friction between the clamping disc and the trim strip, preventing the trim strip from sliding and shifting during use. At the same time, the silicone material is soft and will not scratch the surface of the trim strip, thus protecting its appearance.

[0015] Furthermore, the edge of the fixed suction cup is provided with an elastic sealing lip, which is made of nitrile rubber. This enhances the tightness of the fixed suction cup against the car door surface, prevents external rainwater, dust, mud and other impurities from entering through the gaps at the edge of the suction cup, and ensures the durability of the adsorption effect.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This utility model provides an automotive door trim strip.

[0018] (1) By switching the settings of the trim component, when the operator uses the device, he only needs to pull the control lever and compress the return spring to easily lift the clamping round plate and pull out the placement plate to replace the trim; then push the placement plate back into place, release the control lever, and the return spring will drive the clamping round plate to press down, which, together with the anti-slip protrusion, will firmly fix the trim, so as to realize the quick and convenient switching of the door trim style and meet the diverse decoration needs of users.

[0019] (2) By setting the fixing components, when the personnel operate the device, the fixing suction cup is pressed on the surface of the car door, and the door trim is quickly fixed by its adsorption force. The damping telescopic device adapts to fit the car door to ensure that it is firmly fixed. During the vehicle's operation, the damping telescopic device buffers the vibration and, together with the suspension rope, assists in fixing, effectively preventing the door trim from loosening and falling off, and ensuring safe and stable use.

[0026] 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.

[0027] To solve the problem of how to effectively position and adjust the technology, such as Figure 1-5 As shown, the following preferred technical solutions are provided:

[0028] A car door trim strip includes a fixed base plate 1. A trim strip switching assembly 2 is fixedly connected to the center of the top of the fixed base plate 1. By using the trim strip switching assembly 2, when the user operates the device, simply pulling the control lever 204 compresses the return spring 205 to easily lift the clamping round plate 206, allowing the placement plate 207 to be pulled out for trim strip replacement. Then, pushing the placement plate 207 back into place and releasing the control lever 204 causes the return spring 205 to press down the clamping round plate 206, which, together with the anti-slip protrusions, securely fixes the trim strip. This allows for quick and convenient switching of door trim strip styles, meeting diverse decorative needs of users. Fixing components 3 are fixedly connected to both sides of the top of the fixed base plate 1. The device is designed so that when the operator uses it, the suction cup 304 is pressed onto the door surface to quickly fix the door trim using its suction force. The damping telescopic device 302 adaptively adjusts to fit the door to ensure a firm fixation. During vehicle operation, the damping telescopic device 302 buffers vibrations and works with the suspension rope 306 to assist in fixing, effectively preventing the door trim from loosening and falling off, ensuring safe and stable use. The trim switching assembly 2 includes a connecting plate 201 fixedly connected to the top center of the fixed base plate 1. Fixing plates 202 are fixedly connected to both sides of the surface of the connecting plate 201. A sliding rod 203 is slidably connected to the inner wall of the fixing plate 202, and a control rod 204 is fixedly connected to the surface of the sliding rod 203.

[0029] Specifically, when using the operating device, the operator first places the fixed base plate 1 at the corresponding door installation position, and then presses the fixing suction cup 304 of the fixing component 3 to complete the initial fixing of the door trim base; when it is necessary to change the trim style, hold the control handle 208 with one hand to stabilize the plate 207, and pull the control lever 204 upward with the other hand to start the switching operation.

[0030] Furthermore, such as Figure 3 As shown, the following preferred technical solutions are provided:

[0031] A return spring 205 is fixedly connected to the surface of the sliding rod 203, and a clamping disc 206 is fixedly connected to the bottom end of the sliding rod 203. The purpose of this design is to lift the control rod 204 to move the sliding rod 203 upward, compress the return spring 205 to make the clamping disc 206 detach from the trim strip, and create unobstructed space for trim strip replacement; after replacement, the control rod 204 is released, the return spring 205 releases elastic potential energy to push the sliding rod 203 downward, so that the clamping disc 206 precisely presses down to fix the trim strip, realizing an automated fixing process of lifting to unlock, replacing and resetting to lock.

[0032] Furthermore, such as Figure 2 As shown, the following preferred technical solutions are provided:

[0033] The top of the connecting plate 201 is slidably connected to the placement plate 207, and the surface of the placement plate 207 is fixedly connected to the control handle 208. The purpose of this design is to enable the placement plate 207 to be pulled out by the control handle 208, which makes it convenient to take out the trim strip from the inside of the door for style change, and also allows for precise adjustment of the alignment between the trim strip and the door during installation. At the same time, the pull-out structure makes the trim strip replacement process without additional tools, improving the convenience of operation.

[0034] Furthermore, such as Figure 4 As shown, the following preferred technical solutions are provided:

[0035] The fixing component 3 includes a fixing circular plate 301 fixedly connected to both sides of the top of the fixing base plate 1. Four damping expansion joints 302 are distributed in a ring on the back of the fixing circular plate 301. The purpose of this design is to utilize the dynamic buffering characteristics of the damping expansion joints 302 to maintain the tight fit between the fixing suction cup 304 and the door when there is curvature or slight concavity on the door surface through adaptive expansion and contraction. At the same time, during vehicle operation, the damping structure can absorb more than 80% of the vibration energy, avoid the attenuation of the adsorption force due to vibration, and ensure the long-term stable installation of the door trim.

[0036] Furthermore, such as Figure 4 As shown, the following preferred technical solutions are provided:

[0037] A fixed circular block 303 is fixedly connected to the surface of the damping expansion joint 302, and a fixed suction cup 304 is fixedly connected to the surface of the fixed circular block 303. The purpose of this design is to use the fixed circular block 303 as a structural conversion component to accurately transmit the expansion and contraction movement of the damping expansion joint 302 to the fixed suction cup 304. The fixed suction cup 304 adopts the principle of vacuum adsorption. After pressing, it can form a negative pressure cavity and generate an adsorption force of more than 30N. Combined with the damping structure, it achieves a dual fixing effect of flexible fit and strong adsorption.

[0038] Furthermore, such as Figure 4 As shown, the following preferred technical solutions are provided:

[0039] Both sides of the top of the fixed circular plate 301 are fixedly connected to connecting circular blocks 305. The surface of the connecting circular blocks 305 is fixedly connected to a hanging rope 306. The purpose of this design is that after the door trim strip is removed, it can be hung on the storage hook or repair bay inside the vehicle by the hanging rope 306 to avoid surface scratches caused by random placement of the trim strip. When the vehicle is washed, the hanging rope 306 can temporarily fix the door trim strip to keep it at a safe distance from the door and prevent damage to the parts caused by the impact of the high-pressure water gun.

[0040] Furthermore, such as Figure 3 As shown, the following preferred technical solutions are provided:

[0041] The bottom surface of the clamping disc 206 is provided with anti-slip protrusions. The anti-slip protrusions are distributed in a hemispherical array and are made of silicone material. The purpose of this design is that the hemispherical protrusions can form multiple points of contact with the surface of the trim strip. Under the same pressure, the contact area is increased by 40%. Combined with the high friction coefficient of silicone material of 0.8, it effectively prevents the trim strip from shifting when the vehicle is bumpy. At the same time, the soft silicone material can be slightly deformed under pressure to form a wrapping clamping effect, which ensures the fixing strength and avoids damage to the surface coating of the trim strip.

[0042] Furthermore, such as Figure 4 As shown, the following preferred technical solutions are provided:

[0043] The edge of the fixed suction cup 304 is provided with an elastic sealing lip. The elastic sealing lip is made of nitrile rubber. The purpose of this design is that the excellent elasticity of nitrile rubber allows the sealing lip to fit tightly against the slight concavity and convexity of the car door surface, forming an all-round sealing structure, effectively preventing rainwater, mud, dust and other external impurities from seeping in from the edge of the suction cup.

[0044] Working principle: During installation, the fixing base plate 1 is first placed in the predetermined position on the car door. Pressing the fixing suction cup 304 expels air and forms an adsorption force. The damping telescopic device 302 automatically adjusts to ensure that the four suction cups are evenly stressed and fixed. When replacing the trim strip, pulling the control lever 204 compresses the return spring 205, which drives the clamping round plate 206 to rise and release the fixation. Pulling the control handle 208 pulls out the placement plate 207 to replace the trim strip. The return control lever 204 causes the clamping round plate 206 to press down and fix the new trim strip. During vehicle operation, the damping telescopic device 302 continuously buffers vibration, and the suspension rope 306 provides auxiliary limit under extreme vibration conditions to ensure that the door trim strip always remains stable.
