Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a shock-absorbing and vibration-damping electric vehicle interior assembly clip. Background Technology

[0002] Automotive interior components, such as door panels, headliners, and dashboards, are important components of the car's interior space. They not only beautify the interior environment and improve driving comfort, but also play an auxiliary role in sound insulation and noise reduction. In order to securely install these interior components onto the car body frame, the industry generally uses a large number of assembly clips for connection. The main goal of these traditional clip designs is to achieve quick snap-fit ​​fixing.

[0003] However, most existing snap-fit ​​structures are relatively simple. In actual assembly, workers often need to rely on experience to align the snap points and apply considerable pressure to complete the fitting. This method of operation is not only inefficient, but also prone to damage to the snap-fit ​​or interior panel connection parts during repeated disassembly and repair, increasing manufacturing costs and maintenance difficulty. More importantly, these traditional rigid snap-fits have almost no cushioning and shock absorption capabilities, and they directly and rigidly connect the interior panel to the vehicle body.

[0004] In traditional gasoline-powered vehicles, the engine itself generates significant noise and vibration, which often masks minor vibrations and rattles caused by rigid connections. However, with the rapid development of the automotive industry towards electrification, electric vehicles, lacking the engine noise source, have an exceptionally quiet interior environment. This makes various minor noises caused by road bumps, body resonance, and especially rattles caused by vibration and friction between interior components particularly prominent. These persistent vibrations and rattles not only severely reduce the comfort of passengers but also, in the long run, accelerate the fatigue and loosening of interior component connections, constituting a technical defect that urgently needs to be addressed.

[0005] Therefore, this utility model proposes a shock-absorbing and vibration-damping electric vehicle interior assembly buckle to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of existing automotive interior assembly clips, such as cumbersome and laborious installation process, insufficient stability and easy loosening after connection, and lack of effective buffering and shock absorption capabilities, which easily lead to vibration and abnormal noise in the quiet interior of electric vehicles, this utility model aims to provide a buffering and shock-absorbing electric vehicle interior assembly clip with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a buffer and shock-absorbing electric vehicle interior assembly buckle, including: a fixing plate, a fixing mechanism disposed on the fixing plate, and a shock-absorbing mechanism; The fixing mechanism includes a fixing block, a locking block, a pull rod, a damping rod one, a connecting rod one, a connecting rod two, a slider, and a fixing rod. The vibration damping mechanism includes a mounting frame, a damping rod two, a rubber block, a crank one, and a crank two.

[0008] Furthermore, the pull rod of the fixing mechanism drives the fixing rod to move, and the fixing rod is linked to the connecting rod one through the connecting rod two and the slider, thereby driving the locking block located in the fixing block to perform opening or closing actions; the rubber block of the vibration damping mechanism is set directly opposite the fixing block of the fixing mechanism, and when the rubber block is compressed, it moves in conjunction with the crank two and the crank one, and simultaneously compresses the damping rod two.

[0009] Preferably, the fixing block is provided with an opening for the insertion of the limiting block of the interior panel, and the locking block is used to engage with the groove of the limiting block.

[0010] Preferably, the fixing mechanism further includes a fixing frame, the fixing rod is slidably installed in the fixing frame, and the damping rod is disposed in the fixing frame and abuts against the fixing rod, for providing a reset thrust after the pull rod is released.

[0011] Preferably, the slider is slidably fitted onto the outer wall of the fixed rod; one end of the second connecting rod is hinged to the fixed rod, and the other end is hinged to the slider; one end of the first connecting rod is hinged to the slider, and the other end is hinged to the locking block.

[0012] Preferably, the vibration damping mechanism further includes a mounting plate, which is fixed inside the mounting frame, and the crank is rotatably connected to the mounting plate.

[0013] Preferably, the rubber block is located between the second damping rod and the fixed block, and both sides of the rubber block are rotatably connected to the first crank via the second crank.

[0014] Preferably, the bottom wall of the fixed plate is fixedly connected with multiple vibration damping mechanisms at equal intervals.

[0015] Preferably, one end of the damping rod two is fixed to the inner wall of the mounting bracket of the vibration damping mechanism, and the other end of the damping rod two is retractably abutted against the rubber block.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problems of complex installation process, reliance on brute force pressing, and insufficient stability and easy loosening of existing interior trim clips by setting up a linkage fixing mechanism composed of pull rod, connecting rod, slider and locking block. The pulling and releasing action of the pull rod controls the automatic opening and resetting locking of the locking block. This achieves convenient and labor-saving installation operation, high assembly efficiency and stable and reliable connection.

[0017] This invention solves the problem that traditional snap-fit ​​mechanisms, which only have rigid connection functions and lack effective buffering and shock absorption capabilities, and thus easily cause interior noise due to vehicle vibration, by setting up a composite vibration damping mechanism that works in concert with rubber blocks, crank connecting rods, and damping rods. It utilizes the buffering effect of rubber blocks, the conduction and dispersion effect of crank connecting rods, and the energy absorption effect of damping rods during vibration transmission. This achieves efficient absorption and dissipation of vibration energy, significantly reduces the vibration frequency of interior parts, and improves the quietness of the entire vehicle and the ride comfort.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0021] Please refer to Figures 1 to 5This utility model provides a buffer and shock-absorbing electric vehicle interior assembly buckle, which aims to solve the problems of existing automotive interior buckles being cumbersome to install, having insufficient connection stability, and lacking effective buffering and shock absorption capabilities.

[0022] like Figures 1 to 3 As shown, the basic frame of a shock-absorbing electric vehicle interior trim assembly clip consists of a fixed plate 1, a fixing mechanism 2 mounted on the fixed plate 1, and a vibration damping mechanism 3. The fixed plate 1 is a long strip plate that serves as the mounting base for the entire device. The fixed plate 1 is fixed to the vehicle body structure with bolts through pre-drilled mounting holes. The fixing mechanism 2 is used to achieve a detachable assembly connection with the interior trim panel 202. The vibration damping mechanism 3 is used to dampen the vibration of the fixing mechanism 2 and even the entire interior trim panel 202. To achieve coordinated operation, multiple vibration damping mechanisms 3 are fixedly connected to the bottom wall of the fixed plate 1 at equal intervals through their mounting brackets 301. The fixing mechanism 2 is correspondingly mounted on the bottom wall of the fixed plate 1, and the fixing block 201 of the fixing mechanism 2 is connected to the damping mechanism 3. The vibration damping mechanism 3 is precisely aligned along the main direction of vibration transmission. The external operable part of the fixing mechanism 2 is a pull rod 206. The fixing block 201 is a component that directly interacts with the limiting block 203 on the interior panel 202. The fixing block 201 has a roughly rectangular opening to accommodate the limiting block 203. The basic structure of the vibration damping mechanism 3 includes a mounting frame 301 and a mounting plate 302 fixed in the mounting frame 301. The mounting frame 301 ensures a stable connection between the vibration damping mechanism 3 and the fixing plate 1. This overall layout integrates the fixing mechanism 2, which is responsible for locking, and the vibration damping mechanism 3, which is responsible for shock absorption, in a structural manner, so that vibration can be effectively transmitted from the fixing block 201 to the vibration damping mechanism 3, creating a structural foundation for subsequent buffering and energy absorption.

[0023] Please refer to Figure 3 and Figure 4The fixing mechanism 2 includes a fixing block 201 and a fixing frame 205 as mounting bases, a locking block 204 for locking action, a pull rod 206, a damping rod 207, a connecting rod 208, a connecting rod 209, a slider 210, and a fixing rod 211. The fixing frame 205 is fixedly connected to the fixing plate 1 as a support housing for the linkage mechanism. The fixing rod 211 is rod-shaped and slidably passes through the inner cavity of the fixing frame 205 along its axial direction. The pull rod 206 is fixedly connected to the end of the fixing rod 211 away from the fixing block 201 and extends out of the fixing frame 205 for manual operation. The damping rod 207 is spring-shaped or hydraulic rod-shaped and is sleeved on a part of the outer periphery of the fixing rod 211. One end of the damping rod 207 abuts against the inner end wall of the fixing frame 205, and the other end... The slider 210, acting as the core of motion conversion, slides against the flange of the fixed rod 211 and slides on the outer wall of the fixed rod 211. One end of the connecting rod 209 is rotatably connected to the rod body of the fixed rod 211, and the other end is rotatably connected to the slider 210. One end of the connecting rod 208 is rotatably connected to the slider 210, and the other end is rotatably connected to the claw-shaped locking block 204. The locking block 204 can be opened and closed and is housed in the internal cavity of the fixed block 201. This linkage system, consisting of multiple connecting rods and the slider 210, can efficiently convert the linear tension applied by the pull rod 206 into the sliding of the slider 210 on the fixed rod 211, and ultimately drive the locking block 204 to open synchronously, creating space for the insertion of the limiting block 203 on the interior panel 202, thus achieving convenient operation.

[0024] Based on the above embodiments, the technical solution of this utility model can be further specified. As a preferred embodiment, in order to form a reliable docking and locking with the interior panel 202, the fixing block 201 is provided with an opening of matching size and shape, which is specifically used for the insertion of the limiting block 203 on the interior panel 202. The end of the locking block 204 has a claw shape that matches the groove, which can accurately lock into the groove preset in the inner wall of the limiting block 203 when closed, forming a firm mechanical lock. In order to achieve this precise linkage control, the middle part of the fixing rod 211 is rotatably connected to one end of the connecting rod 209 through a pin shaft. The other end of the connecting rod 209 is rotatably connected to the slider 210. At the same time, one end of the connecting rod 208 is also rotatably connected to the slider 210, and the other end of the connecting rod 208 is rotatably connected to the drive arm of the locking block 204. This four-bar linkage plus slider 210 mechanism ensures the accuracy of motion transmission.

[0025] For a preferred design of vibration damping mechanism 3, please refer to... Figure 4 and Figure 5The mounting bracket 301 has a mounting plate 302 fixedly welded inside, providing a mounting base for the internal moving components. Crank 1 303 is rotatably connected to the mounting plate 302 via bearings or pins. Both sides of the rubber block 305 are rotatably connected to one end of crank 2 306 via pins, and the other end of crank 2 306 is rotatably connected to the corresponding crank 1 303, forming a symmetrical planar linkage mechanism. Damping rod 2 304, as the core energy-absorbing element, has one end flanged or welded to the inner wall of the mounting bracket 301, and its retractable piston rod end always elastically abuts against the inner surface of the rubber block 305, ready to bear the pressure transmitted by the rubber block 305 at any time. In order to achieve a uniform buffering effect on the large-area interior panel 202, multiple vibration damping mechanisms 3 with the same structure can be fixedly connected at equal intervals along the length direction on the bottom wall of the fixed plate 1 to form a vibration damping matrix that works in concert.

[0026] Working principle: When installing the interior trim panel 202, the operator first pulls the pull rod 206 outward. The pull rod 206, through its fixed connection with the fixed rod 211, drives the fixed rod 211 to move axially outward within the cavity of the fixing frame 205. During the movement of the fixed rod 211, its body compresses the damping rod 207, which serves as a reset element, causing the damping rod 207 to store elastic potential energy. At the same time, the movement of the fixed rod 211 forces the slider 210 to slide along the outer wall of the fixed rod 211 through the rotating connecting rod 209. The sliding displacement of the slider 210 is then precisely converted into the inward retraction of the locking block 204 through the rotating connecting rod 208, causing multiple locking blocks to... Block 204 converges towards the center synchronously within the inner cavity of fixed block 201, thus providing sufficient installation space at the opening of fixed block 201. At this point, the limiting block 203 on the interior panel 202 can be easily inserted into the opening of fixed block 201. Subsequently, the operator releases the pull rod 206, and under the elastic force stored in the damping rod 207, the fixing rod 211 is pushed back to its initial position. Through the aforementioned connecting rod and slider 210 mechanism, the locking block 204 is driven to extend in the opposite direction, so that the claw part of the locking block 204 is precisely engaged in the groove on the inner wall of the limiting block 203, forming a stable and reliable mechanical lock. The entire assembly process is convenient to operate and greatly improves installation efficiency. During the operation of an electric vehicle, when the vehicle body vibrates due to uneven road surfaces, the vibration is transmitted through the vehicle structure to the rigidly fixed plate 1, and then rapidly transmitted to the fixed block 201 of the fixing mechanism 2. This causes the fixed block 201 to act as an impactor, striking the rubber block 305 of the damping mechanism 3 directly opposite it at high frequency. After being impacted, the rubber block 305 undergoes elastic deformation and transmits the impact force inward. This process produces a dual damping effect. First, the movement of the rubber block 305 directly compresses and abuts against the damping rod 304 behind it. When the piston rod of the damping rod 304 moves within the cavity, the internal damping medium efficiently converts the intense vibration kinetic energy into heat energy and dissipates it. Firstly, the core of the process is to disperse the vibration energy. Secondly, as the rubber block 305 moves under pressure, it also drives the crank 303 to rotate around the fulcrum on the mounting plate 302 via the crank 306 connected to its two sides. This symmetrical crank-connecting rod mechanism plays a role in dispersing and transmitting the impact force, assisting in the energy dissipation process and avoiding stress concentration. Through the initial buffering of the rubber block 305, the transmission and dispersion of the crank-connecting rod mechanism, and the core energy absorption of the damping rod 304, this invention can significantly reduce the vibration amplitude and frequency transmitted to the interior panel 202, effectively suppress abnormal noises caused by vibration, improve ride comfort, and extend the service life of interior components.
