Description

Technical Field

[0001] This utility model relates to the field of sealing strip technology, and in particular to a magnetic adsorption automotive sealing strip structure. Background Technology

[0002] With the development of the automotive industry, consumers have placed higher demands on the sealing, comfort, and durability of vehicles. Traditional automotive sealing strips mainly rely on the elastic deformation of rubber to fill the gap between the door and the body to achieve a sealing effect.

[0003] Existing magnetic adsorption automotive sealing strip structures are prone to rubber aging and wear, resulting in loss of elasticity and decreased sealing performance during long-term use. This can lead to problems such as rainwater leakage and noise intrusion. At the same time, vibrations during vehicle operation and the impact from frequent door opening and closing can also accelerate the damage to the sealing strip. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a magnetic adsorption automotive sealing strip structure.

[0005] This utility model is achieved by the following technical solution: a magnetic adsorption automotive sealing strip structure, including a sealing strip body, the sealing strip body including a clamping device, and a buffer device provided on the top of the clamping device;

[0006] The clamping device includes a sealing strip, a U-shaped clamping block is fixedly connected to the right side of the sealing strip, clamping teeth are fixedly connected to the inner wall of the U-shaped clamping block, a snap-fit ​​post is fixedly connected to the left side of the sealing strip, and a support rod is fixedly connected to the bottom of the inner wall of the sealing strip.

[0007] The above technical solution involves setting a number of connecting rods, which are staggered with the support rods.

[0008] As a further improvement to the above solution, the number of support rods is set to several, and the surface of the support rods penetrates the top of the inner wall of the sealing strip.

[0009] Through the above technical solution, the support rod runs through the top of the inner wall of the sealing strip, buffers and reinforces the bottom of the inner wall of the reinforcing strip and the pressure plate. On the one hand, it serves as a guide rail for the sliding of the pressure plate, ensuring that the displacement direction of the pressure plate is accurate during the buffering process and avoiding lateral displacement that affects the seal. On the other hand, it evenly transmits the magnetic strip adsorption force to the entire sealing strip structure, reducing local deformation and preventing the sealing strip from softening and collapsing under long-term stress or high temperature.

[0010] As a further improvement to the above solution, the buffer device includes a buffer reinforcing strip, a magnetic strip is fixedly connected to the top of the inner wall of the buffer reinforcing strip, a connecting rod is fixedly connected to the bottom of the magnetic strip, and a pressure plate is fixedly connected to the bottom of the connecting rod.

[0011] As a further improvement to the above solution, the buffer reinforcement strip is located at the top of the sealing strip, and the bottom of the buffer reinforcement strip is fixedly connected to the top of the sealing strip.

[0012] As a further improvement to the above solution, the bottom of the inner wall of the buffer reinforcement strip is slidably connected to the support rod.

[0013] As a further improvement to the above solution, the connecting rod passes through the bottom of the buffer reinforcement strip and the top of the sealing strip.

[0014] As a further improvement to the above solution, the surface of the pressure plate is slidably connected to the inner wall of the sealing strip, and the interior of the pressure plate is slidably connected to the surface of the support rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes a pressure plate. When the door closes and compresses the sealing strip, the buffer reinforcement strip deforms under pressure. The magnetic strip drives the connecting rod, which in turn causes the pressure plate to slide along the support rod within the sealing strip. This effectively reduces the rigid impact during door closing, making the closing action smoother and more gentle, thus optimizing the driving experience. Simultaneously, it ensures a tight fit between the magnetic strip and the metal parts of the vehicle body, further improving sealing performance, reducing noise, rainwater, and dust intrusion, and extending the service life of the sealing strip.

[0017] This utility model provides stable support by setting a support rod that passes through the sealing strip and the pressure plate, effectively resisting deformation and torsion caused by external forces, enhancing the overall structural strength, guiding the pressure plate to slide smoothly, making the displacement of the buffer device more precise and controllable when under force, and evenly dispersing the pressure generated by the magnetic strip adsorption, avoiding local stress concentration, and ensuring that the sealing strip maintains good sealing effect and structural stability during long-term use.

[0025] Example:

[0026] Please combine Figure 1-4 The present embodiment of a magnetic adsorption automotive sealing strip structure includes a sealing strip body 1, the sealing strip body 1 includes a clamping device 2, and a buffer device 3 is provided on the top of the clamping device 2.

[0027] The clamping device 2 includes a sealing strip 201. A U-shaped clamping block 202 is fixedly connected to the right side of the sealing strip 201. A clamping tooth 203 is fixedly connected to the inner wall of the U-shaped clamping block 202. A snap-fit ​​post 204 is fixedly connected to the left side of the sealing strip 201. A support rod 205 is fixedly connected to the bottom of the inner wall of the sealing strip 201. The sealing strip 201, in conjunction with the U-shaped clamping block and the clamping tooth 203, bites into the vehicle body mounting part. The snap-fit ​​post 204 is convenient to cooperate with the corresponding slot.

[0028] There are several support rods 205, and the surface of the support rod 205 penetrates the top of the inner wall of the sealing strip 201.

[0029] The buffer device 3 includes a buffer reinforcing strip 301. A magnetic strip 302 is fixedly connected to the top of the inner wall of the buffer reinforcing strip 301. A connecting rod 303 is fixedly connected to the bottom of the magnetic strip 302. A pressure plate 304 is fixedly connected to the bottom of the connecting rod 303. The magnetic strip 302 and the metal parts of the vehicle body generate an adsorption force to achieve a seal. When the door closes and squeezes the sealing strip, the buffer reinforcing strip 301 is deformed by pressure. The magnetic strip 302 drives the connecting rod 303. The connecting rod 303 drives the pressure plate 304 to slide along the support rod 205 inside the sealing strip 201. The magnetic strip 302 is placed on top of the support rod 205, which effectively absorbs the impact force of closing the door and avoids rigid collisions. It not only ensures the sealing effect of magnetic adsorption, but also buffers and reduces shock, isolates external noise, rain and dust, and significantly improves the sealing performance of the vehicle interior and the comfort of the ride.

[0030] The cushioning reinforcement strip 301 is located on top of the sealing strip 201, and the bottom of the cushioning reinforcement strip 301 is fixedly connected to the top of the sealing strip 201.

[0031] The bottom of the inner wall of the buffer reinforcement strip 301 is slidably connected to the support rod 205.

[0032] The connecting rod 303 passes through the bottom of the buffer reinforcement strip 301 and the top of the sealing strip 201.

[0033] The surface of the pressure plate 304 is slidably connected to the inner wall of the sealing strip 201, and the interior of the pressure plate 304 is slidably connected to the surface of the support rod 205.

[0034] The implementation principle of the magnetic adsorption automotive sealing strip structure in this application embodiment is as follows: the sealing strip 201, together with the U-shaped clamping block and the clamping teeth 203, bites into the body mounting part, and the snap-fit ​​post 204 facilitates the engagement with the corresponding slot. The magnetic strip 302 generates an adsorption force with the metal parts of the body to achieve a seal. When the door closes and squeezes the sealing strip, the buffer reinforcing strip 301 is deformed by pressure, and the magnetic strip 302 drives the connecting rod 303. The connecting rod 303 drives the pressure plate 304 to slide along the support rod 205 inside the sealing strip 201. The magnetic strip 302 is placed on the top of the support rod 205, which effectively absorbs the impact force of closing the door and avoids rigid collision. This not only ensures the sealing effect of magnetic adsorption, but also buffers and reduces shock, isolates external noise, rain and dust, and significantly improves the sealing performance and driving comfort of the vehicle interior.
