Description

Technical Field

[0001] This utility model relates to the technical field of automotive hood sound insulation pads, specifically an automotive hood vibration damping and sound insulation pad. Background Technology

[0002] The car hood, also known as the engine cover or hood, is the top cover of the car's engine compartment. It is usually a large and flat metal plate. The car hood protects the engine and its surrounding pipelines, circuits, oil lines, braking system and other important components from impact and interference, ensuring the normal operation of the vehicle. The inside of the car hood is usually equipped with corresponding sound insulation pads to absorb and reduce the noise generated during engine operation, thereby improving the comfort of the car.

[0003] As disclosed in announcement number CN204937003U, a sound-absorbing pad for a vehicle hood is designed. The pad has grooves along its circumference, with a depth of 15-25mm to accommodate different cavities on the hood. It also features snap-fit ​​holes to further strengthen the connection between the pad and the cavities. The pad has a five-layer structure: two layers of felt on the top and bottom, with sponge, plant cellulose, and centrifugal glass wool in between. This design, utilizing the interlocking of the grooves with the inner wall of the hood and the locking mechanism, effectively secures the pad to the hood. The five-layer structure provides excellent sound insulation and absorption, ensuring a comfortable driving experience for the driver.

[0004] However, existing technologies, while able to insulate heat, do not readily dissipate heat, resulting in poor heat dissipation. Furthermore, dust can accumulate inside the hood during vehicle operation, making it difficult to clean. For example, the comparative patents listed above have this problem.

[0005] To address this issue, we propose a car hood vibration damping and sound insulation pad. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a car hood vibration damping and sound insulation pad, comprising a hollow rubber sound insulation pad and a fleece layer embedded in the lower end of the rubber sound insulation pad;

[0008] Also includes:

[0009] An embedded middle sponge layer is set in the middle of the rubber sound insulation pad, and a curved cooling pipe is set in the middle sponge layer;

[0010] A nylon fiber layer is attached to the lower end of the fleece layer, and multiple dust-absorbing cloths are attached to the lower end of the nylon fiber layer.

[0011] As a preferred technical solution of this utility model, the rubber sound insulation pad is fixed with mounting ear plates at both ends, and the mounting ear plates are provided with mounting holes in the middle, and fastening bolts for connecting with the machine cover are provided through the mounting holes.

[0012] Using the above technical solution, mounting ears are fixed at both ends of the rubber sound insulation pad, and mounting holes are opened in the middle of the mounting ears. At the same time, fastening bolts for connecting with the machine cover are installed through the mounting holes, which facilitates the connection between the rubber sound insulation pad and the machine cover.

[0013] As a preferred technical solution of this utility model, the intermediate sponge layer has a curved groove with the same shape and direction as the cooling pipe, and the cooling pipe is engaged in the curved groove, and both ends of the cooling pipe are connected through the rubber sound insulation pad.

[0014] The above technical solution involves creating a curved groove in the middle sponge layer that has the same shape and direction as the cooling pipe, with the cooling pipe engaged in the groove. Both ends of the cooling pipe are connected to the rubber sound insulation pad, which facilitates heat dissipation. Furthermore, the actual heat absorption area is large, resulting in high heat dissipation efficiency.

[0015] As a preferred embodiment of this utility model, the cooling pipe has an inlet end on the left side and an outlet end on the right side, and the inlet end, the cooling pipe and the outlet end together with the external circulation pump and the cooling water tank form a cooling circuit.

[0016] By adopting the above technical solution, an inlet is provided on the left side of the cooling pipe and an outlet is provided on the right side of the cooling pipe. The inlet, cooling pipe and outlet, together with the external circulation pump and cooling water tank, form a cooling circuit, which can quickly and continuously dissipate heat to the outside and extend the service life of the sound insulation pad.

[0017] As a preferred embodiment of this utility model, a first Velcro fastener is provided at the upper edge of the fleece layer and the lower edge of the rubber sound insulation pad, and the fleece layer and the rubber sound insulation pad are connected by the first Velcro fastener.

[0018] As a preferred embodiment of this invention, the lower end of the nylon fiber layer is connected to the dust-absorbing cloth via a second Velcro fastener.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: The car hood vibration damping and sound insulation pad senses the temperature through a temperature sensor. When the temperature is too high, it forms a cooling circuit with the cooling pipe, inlet and outlet, together with the external cooling water tank and circulation pump. This circuit can dissipate heat in time for continuous cooling, which provides good protection for the sound insulation pad as a whole and extends its service life. In addition, the dust-absorbing cloth can absorb dust on the inside of the hood, and the second Velcro fastener allows for regular removal and replacement of the dust-absorbing cloth.

The cooling pipe, the inlet end and the outlet end, as well as the external circulation pump and the cooling water tank form a cooling circuit, which facilitates the removal of heat. Moreover, the cooling pipe is curved, which increases the actual heat absorption area and achieves better heat dissipation effect.

[0022] 2. It is equipped with a nylon fiber layer and a dust-absorbing cloth. The dust-absorbing cloth is set at the lower end of the nylon fiber layer by a second Velcro fastener. The dust-absorbing cloth can absorb dust on the inside of the cover. In addition, the dust-absorbing cloth can be disassembled and replaced periodically. Attached Figure Description
