Description

Technical Field

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

[0002] The inner door panel of a car is one of the most critical components in the car door system. It is an important part of the door assembly, serving to protect occupants and support the outer door panel. It also provides mounting points for accessories such as door guards, window regulators, water cutters, sealing strips, and anti-collision beams. Therefore, a specific structure for the inner door panel of a car is required.

[0003] When the existing car door inner panel structure is in operation, the vibration of the car body is transmitted to the inner panel when the car is moving. The vibration of the inner panel in turn causes the surrounding air to vibrate, generating noise. In addition, the car door vibrates when it is closed. Therefore, there is an urgent need for a new car door inner panel structure. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an automotive door inner panel structure to solve the problems of existing automotive door inner panel structures, where vibrations of the car body are transmitted to the door inner panel during operation, causing the vibration of the door inner panel to cause noise from the surrounding air, and vibrations when the car door is closed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automotive door inner panel structure, including an inner panel body, a noise reduction plate installed inside the inner panel body, bolts installed on the inner wall of the noise reduction plate, a first rubber ring provided on the outer wall of the connecting rod, and a second rubber ring adhered to the inner wall of the inner panel body.

[0006] A piston rod is installed on the inner wall of the vehicle interior panel body, a damping sleeve is provided on the outer wall of the piston rod, a buffer spring is welded to the outer wall of the damping sleeve, and a rubber pressure head is installed at one end of the damping sleeve.

[0007] Preferably, the interior panel body is threadedly connected to the connecting rod, and the inner wall of the interior panel body is threaded.

[0008] Preferably, the noise reduction plate is threadedly connected to the connecting rod, and the inner wall of the noise reduction plate is provided with a honeycomb structure.

[0009] Preferably, the inner wall of the vehicle interior panel body is tightly fitted to the outer wall of the second rubber ring, and the inner wall diameter of the vehicle interior panel body is larger than the outer wall diameter of the second rubber ring.

[0010] Preferably, the buffer spring and the piston rod are arranged in parallel, and the inner wall of the piston rod is designed with openings.

[0011] Preferably, the connecting rod is tightly fitted with the first rubber ring, and the inner diameter of the first rubber ring is larger than the outer diameter of the connecting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses a connecting rod to fix the noise reduction plate to the vehicle interior panel body. The noise reduction plate adopts a honeycomb design. Through the dual function of storing and absorbing energy, the honeycomb noise reduction plate can significantly reduce the intensity of noise, thereby achieving a good noise reduction effect. Through the first rubber ring and the second rubber ring, the friction noise generated between the noise reduction plate, the vehicle interior panel body and the connecting rod can be effectively reduced.

[0014] 2. This utility model constructs an effective buffer and anti-collision component by setting up a damping sleeve, a piston rod, and a buffer spring. When it comes into contact with the rubber pressure head, the rubber pressure head will drive the damping sleeve and the piston rod to compress, causing the buffer spring to compress synchronously. This converts the energy of the direct impact into the elastic potential energy of the spring, greatly reducing the impact force and thus reducing the vibration that occurs when the car door closes.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] The embodiments of this utility model will be described below based on its overall structure.

[0024] Please see Figure 1-6 A car door inner panel structure includes a noise reduction plate 2 installed inside the inner panel body 1. Connecting rods 3 are installed on the inner walls of the noise reduction plate 2. The connecting rods 3 are tightly fitted with a first rubber ring 4, and the inner diameter of the first rubber ring 4 is larger than the outer diameter of the connecting rod 3. The inner panel body 1 is threadedly connected to the connecting rods 3, and the inner wall of the inner panel body 1 is threaded. A first rubber ring 4 is provided on the outer wall of each connecting rod 3. The noise reduction plate 2 is threadedly connected to the connecting rods 3, and the inner wall of the noise reduction plate 2 has a honeycomb structure. A first rubber ring 4 is adhered to the inner wall of the inner panel body 1. The inner wall of the vehicle interior panel body 1 is tightly fitted with the outer wall of the second rubber ring 5, and the inner wall diameter of the vehicle interior panel body 1 is larger than the outer wall diameter of the second rubber ring 5. The noise reduction plate 2 is fixed to the vehicle interior panel body 1 by the connecting rod 3. The noise reduction plate 2 adopts a honeycomb design. Through the dual function of storage and energy absorption, the honeycomb noise reduction plate 2 can significantly reduce the intensity of noise, thereby achieving a good noise reduction effect. Through the first rubber ring 4 and the second rubber ring 5, the friction noise generated between the noise reduction plate 2, the vehicle interior panel body 1 and the connecting rod 3 can effectively play a role in noise reduction.

[0025] Please see Figure 1-6 A car door inner panel structure includes a piston rod 6 installed on the inner wall of the inner panel body 1, a damping sleeve 7 installed on the outer wall of the piston rod 6, a buffer spring 8 arranged parallel to the piston rod 6, and an open-hole design on the inner wall of the piston rod 6. The buffer spring 8 is welded to the outer wall of the damping sleeve 7, and a rubber pressure head 9 is installed at one end of the damping sleeve 7. The damping sleeve 7, piston rod 6, and buffer spring 8 constitute an effective buffer and anti-collision component. When the rubber pressure head 9 is in contact with the door, the rubber pressure head 9 will drive the damping sleeve 7 and piston rod 6 to compress, causing the buffer spring 8 to compress synchronously. This converts the energy of the direct impact into the elastic potential energy of the spring, greatly reducing the impact force and thus reducing the vibration that occurs when the car door is closed.

[0026] Working principle: In use, the noise reduction plate 2 is fixed to the vehicle interior panel body 1 via the connecting rod 3. The second rubber ring 5 is installed inside the vehicle interior panel body 1, and the first rubber ring 4 is installed between the noise reduction plate 2 and the connecting rod 3. The rubber pressure head 9 is moved. When the car door is closed, the rubber pressure head 9 will squeeze the damping sleeve 7 and the buffer spring 8. When it rebounds, the damping sleeve 7 and the piston rod 6 are moved. This completes the use of the device. The contents not described in detail in this manual are existing technologies known to those skilled in the art.
