Description

Technical Field

[0001] This utility model relates to the technical field of front door lower trim panel mounting brackets, and in particular to a front door lower trim panel anti-vibration mounting bracket. Background Technology

[0002] Front door lower trim panel vibration damping mounts are typically used in the front door area of ​​automobiles. Their purpose is to support and secure the trim panel, reducing damage or loosening caused by vibration. They are generally made of high-strength materials (such as plastic or metal) to ensure that the door panel and interior trim components can be securely installed and remain stable during vehicle operation, reducing the transmission of noise and vibration.

[0003] Patent document CN221873964U discloses a securely mounted front door lower trim panel assembly, including a car door, a front lower trim panel assembly, and a mounting mechanism. The mounting mechanism is provided on one side of the car door surface, and an adjustment mechanism is provided inside the storage box. This securely mounted front door lower trim panel assembly, through the mounting mechanism, allows for installation on the car door. Pulling the handle causes a limiting post to slide, compressing a spring. When the limiting post is fully engaged in the movable groove, the front lower trim panel assembly is fitted into the car door, with the limiting groove and movable groove aligned. Releasing the force applied to the handle causes the spring to return the limiting post to its original position, with one end of the limiting post engaged in the limiting groove. Simultaneously, a stop block engages in the engagement groove, thus securing the front lower trim panel assembly to one side of the car door surface.

[0004] However, the existing front door lower trim panel mounting bracket is difficult to effectively resist the bending stress generated by the lower trim panel when it is subjected to impact and pressure. This can easily lead to deformation of the mounting bracket, poor support strength, and insufficient impact resistance. Utility Model Content

[0016] (III) Beneficial Effects

[0017] This utility model provides a shockproof mounting bracket for the lower trim panel of a front door, which has the following advantages:

[0018] 1. This front door lower trim panel shockproof mounting bracket, through the setting of L-shaped support sheet metal and support buffer components, ensures that when the lower trim panel is subjected to impact force and the mounting bracket is fixed, the L-shaped support sheet metal provides rigid support to the mounting bracket, ensuring that the lower trim panel maintains structural stability under external force and preventing deformation or displacement of the mounting bracket. At the same time, the impact is transmitted to the support sleeve through the fixing bolt, causing the telescopic rod to slide inside the support sleeve. The telescopic rod then compresses the support spring, causing the support spring to deform under force and generate elastic force. The spring deformation absorbs part of the impact energy and compresses the shock-absorbing rubber seat, allowing the shock-absorbing rubber seat to further utilize the elastic deformation characteristics of the material to dissipate the remaining impact force, thereby increasing the mounting bracket's bending resistance. This ensures both installation strength and improved impact resistance, thus enhancing the support strength of the mounting bracket.

[0019] 2. This front door lower trim panel shockproof mounting bracket, through the setting of the limiting component, allows for quick assembly of the lower trim panel when assembly is required. The support seat on the lower trim panel is aligned with the insert rod, and the insert rod is pushed, causing it to compress the telescopic spring and insert into the socket on the support seat. The insert rod is then rotated, aligning the locking block at one end with the slot in the socket. Releasing the insert rod allows the telescopic spring to return to its original shape, pushing the insert rod back into place, and the locking block engages with the slot in the socket. This achieves rapid assembly of the lower trim panel, simplifying the assembly process and improving maintenance or replacement efficiency. Attached Figure Description

The fixed mounting bracket 2 has several internal sliding connections. The limiting component 6 enables rapid assembly of the lower trim panel, simplifying assembly steps and improving maintenance or replacement efficiency. The support and buffer component 5 includes a telescopic rod 501 rotatably connected to the bottom of the movable bolt 4. A positioning rod 7 is fixedly connected to the bottom end of the telescopic rod 501. The positioning rod 7 is slidably connected to the top of the shock-absorbing rubber seat 503. The positioning rod 7 helps to maintain sliding stability. A support sleeve 8 is slidably connected to the surface of the telescopic rod 501. A fixing bolt 9 is rotatably connected to the bottom of the support sleeve 8. The fixing bolt 9 facilitates the rotation of the support sleeve 8. One end of the telescopic rod 501 is fixedly connected to a support spring 502, and one end of the support spring 502 is fixedly connected to a shock-absorbing rubber seat 503; the limiting component 6 includes an insert rod 601 slidably connected inside the fixed mounting bracket 2, one end of the insert rod 601 is inserted into a socket 10, and the socket 10 has two sets of slots that are compatible with the locking blocks 603. The slots facilitate the locking of the locking blocks 603. The surface of the insert rod 601 is fitted with a telescopic spring 602, and one end of the insert rod 601 is fixedly connected to two sets of locking blocks 603.

[0027] Furthermore, a support base 11 is fitted onto the surface of the socket 10, and one end of the support base 11 is fixedly connected to the lower door trim panel 12. The lower door trim panel 12 serves to protect the bottom and decoration of the door. Several sets of threaded holes are formed on the surface of the L-shaped support sheet metal 3, with bolts 13 threadedly connected inside. Limiting holes matching the bolts 13 are formed on the bottom surface of the front door body 1 and the surface of the mounting bracket 2, facilitating the rotational connection of the bolts 13.

[0028] In this invention, the working steps of the device are as follows:

[0029] First step: When the lower trim panel is subjected to impact and pressure on the fixed mounting bracket 2, the L-shaped support sheet metal 3 provides rigid support to the fixed mounting bracket 2, ensuring that the lower trim panel maintains structural stability when subjected to external force, and preventing deformation or displacement of the fixed mounting bracket 2. At the same time, the impact is transmitted to the support sleeve 8 through the fixing bolt 9, causing the telescopic rod 501 to slide inside the support sleeve 8. The telescopic rod 501 then compresses the support spring 502, causing the support spring 502 to deform under force and generate elastic force. The spring deformation absorbs part of the impact energy and compresses the shock-absorbing rubber seat 503, allowing the shock-absorbing rubber seat 503 to further utilize the elastic deformation characteristics of the material to dissipate the remaining impact force.

[0030] The second step: When assembling the lower trim panel, align the support seat 11 on the lower trim panel 12 with the insert rod 601 and insert it. Then push the insert rod 601, causing it to compress the telescopic spring 602 and insert into the socket 10 on the support seat 11. Then rotate the insert rod 601 so that the locking block 603 at one end of the insert rod 601 aligns with the slot in the socket 10. Then release the insert rod 601, causing the telescopic spring 602 to return to its original deformation and push the insert rod 601, and then the locking block 603 engages with the slot in the socket 10.
