In the prior art, the sound insulation board is generally a foam board, which is bonded to the inner wall of the car door inner structure by an adhesive to enhance the sound insulation effect. However, the car door is frequently opened and closed during daily use, and collides with the car door frame. Although a buffer layer is generally provided between the car door and the car door frame, it generally causes the car door to be hit and vibrate. The sound insulation board that is finally installed may fall off from the car door inner structure in a short time under the influence of frequent vibrations, and needs to be disassembled and reinstalled, increasing maintenance costs. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a car door sound insulation board, which solves the problem in the prior art that the sound insulation board may need to be reinstalled in a short period of time, resulting in increased maintenance costs.

[0005] In the above embodiment, the elastic bonding layer is used to bond with the inner wall of the inner structure of the automobile door, and the first groove is configured to produce a suction cup-like effect under the extrusion of the compression layer and the compression member, thereby helping the elastic bonding layer to bond more firmly, thereby making the overall sound insulation board have a longer service life and less prone to falling off, thereby solving the problem in the prior art that the sound insulation board may need to be reinstalled in a short period of time, resulting in increased maintenance costs.

[0006] Furthermore, a threaded sleeve for connecting a clamping piece is connected to the side of the clamping layer away from the elastic bonding layer. The clamping piece is rod-shaped and has a threaded section threadedly connected to the threaded sleeve at one end, and the other end passes through the buffer layer and the covering layer in sequence.

[0007] Furthermore, the pressing piece is also connected with a sleeve ring.

[0008] Furthermore, the second groove is respectively arranged on two sides of the buffer layer.

[0009] Furthermore, the pressing member passes through a second groove on one side and passes through the buffer layer between two second grooves on the other side.

[0010] Furthermore, the covering layer is also connected to a sliding sleeve, and the pressing member is also provided with a sliding section that slidably cooperates with the sliding sleeve.

[0011] Furthermore, the inner diameter of the threaded sleeve is smaller than the inner diameter of the sliding sleeve.

[0012] Furthermore, the collar is fixedly connected with a connecting head, and the pressing piece is provided with a connecting hole for threaded connection of the connecting head.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The pressing member can be used to press the elastic bonding layer against the pressing layer, so that the first groove produces a suction cup-like effect, which helps the elastic bonding layer to bond more firmly. Therefore, the overall sound insulation board has a longer service life and is not prone to falling off, which solves the problem in the prior art that the sound insulation board may need to be reinstalled in a short period of time, resulting in increased maintenance costs.

[0019] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0021] In an exemplary embodiment, Figure 1 , 2As shown, this embodiment provides a car door sound insulation board, which includes an elastic bonding layer 1, a compression layer 2, a buffer layer 3 and a covering layer 4 stacked in sequence, and can be bonded to each other by an adhesive, wherein the elastic bonding layer 1 is made of elastic material, the compression layer 2 and the covering layer 4 can be made of harder plastic material, and the buffer layer 3 can be similar to the elastic bonding layer 1 and use an elastic material such as rubber, and the elastic bonding layer 1 is recessed on one side away from the compression layer 2 to form a plurality of first grooves 5, and the buffer layer 3 includes a plurality of second grooves 6; and also includes a compression piece 7 abutting against the compression layer 2.

[0022] In the above embodiment, the elastic bonding layer 1 is used to bond with the inner wall of the inner structure of the automobile door, and the first groove 5 is provided to produce a suction cup-like effect under the extrusion of the compression layer 2 and the compression member 7, which helps to make the elastic bonding layer 1 bond more firmly, so that the overall sound insulation board has a longer service life and is not easy to fall off, which solves the problem in the prior art that the sound insulation board may need to be reinstalled in a short time, resulting in increased maintenance costs; specifically, the first groove 5 and the second groove 6 are similar, and can also play an auxiliary sound insulation effect, so that the sound insulation board can play a sound insulation role like the sound insulation board in the prior art, and at the same time has a more durable use and reduces the maintenance cost of reinstallation.

[0023] In a further exemplary embodiment, a screw sleeve 8 for connecting a pressing piece 7 is connected to the side of the compression layer 2 facing away from the elastic bonding layer 1. The compression piece 7 is rod-shaped and has a threaded section 9 threadedly connected to the screw sleeve 8 at one end, and the other end is arranged through the buffer layer 3 and the covering layer 4 in sequence. One end of the compression piece 7 is located outside the layer structure, which is convenient for rotation during installation to facilitate connection and disassembly. At the same time, pressure can be applied through this end to make the compression layer 2 more squeezed, thereby making the first groove 5 easier to adsorb. Specifically, during installation, the elastic bonding layer 1 is coated with an adhesive (forming an adhesive layer 10). Through the coordinated adsorption of these adhesives and the first groove 5, the sound insulation board is installed on the inner wall of the car door more firmly.

[0024] In a further exemplary embodiment, there are wiring harnesses in the structure inside the car door, and the installation of the sound insulation board may cause these wiring harnesses to lack a connection and fixing basis. In this embodiment, the clamping piece 7 is also connected to the ring 11. These rings 11 can be elastic rings or plastic rings for positioning the wiring harness and providing an installation basis. The wiring harness passes through the ring 11 and is stuck on the ring 11. Specifically, the ring 11 is fixedly connected to the connector 12, and the clamping piece 7 is provided with a connecting hole for threaded connection of the connector 12, that is, the ring 11 can be detachably connected and can be used as needed.

[0025] In a further detailed exemplary embodiment, the second grooves 6 are respectively arranged on both sides of the buffer layer 3. More specifically, the clamping piece 7 passes through a second groove 6 on one side and passes through the buffer layer 3 between two second grooves 6 on the other side. In addition to assisting in the sound insulation effect, the second grooves 6 also provide a buffering effect. When the structure inside some car doors is large, it can be against the covering layer 4. When vibration occurs, the covering layer 4 squeezes the buffer layer 3 so that the buffer layer 3 is compressed, thereby playing a buffering role.

[0026] In a further detailed exemplary scheme, the covering layer 4 is also connected to the sliding sleeve 13, and the clamping piece 7 is also provided with a sliding section 14 that slides with the sliding sleeve 13. The sliding section 14 ensures that the covering layer 4 will not affect the clamping piece 7 when it is pressed, thereby allowing the buffer layer 3 to play a buffering role without affecting the clamping piece 7. On the other hand, the clamping piece 7 can also avoid affecting the covering plate and the buffer layer 3 when rotating. In particular, the inner diameter of the screw sleeve 8 is smaller than the inner diameter of the sliding sleeve 13, ensuring that the clamping piece 7 can smoothly pass through the sliding sleeve 13.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
