Description

Technical Field

[0001] This utility model relates to the field of automotive design technology, specifically to an automotive motor acoustic package with an adjustable locking buckle. Background Technology

[0002] Automotive motor acoustic packages, as an important component of modern automotive engineering, are designed to significantly improve driving comfort and quietness. With the continuous advancement of automotive technology, the noise and vibration generated by motors have become key factors affecting the overall NVH performance of a vehicle. Therefore, automotive motor acoustic packages have emerged, which are acoustic material packages specifically designed to reduce these adverse factors. Automotive motor acoustic packages contain a variety of high-performance materials, such as sound insulation materials, sound absorption materials, and vibration damping materials. Sound insulation materials primarily isolate sound waves generated by the motor, preventing them from propagating into the passenger compartment; sound absorption materials effectively absorb sound waves, reducing sound reflection and echo; and vibration damping materials reduce the impact of vibration on the entire vehicle by reducing the vibration transmission between the motor and the vehicle body. These materials work together to form a highly effective protective barrier, greatly reducing the interference of motor noise and vibration on passengers.

[0003] A search revealed that the patent document (authorization announcement number CN218276325U) includes a lower layer of felt, topped with an upper layer of felt, and a middle layer of felt between the upper and lower layers. The middle layer of felt contains a sound-insulating cavity, which contains a heat-insulating layer and a buffer layer. The heat-insulating layer and the buffer layer are symmetrically arranged about the central axis of the sound-insulating cavity. A first sound-insulating layer and a second sound-insulating layer are respectively located on the side of the heat-insulating layer and the buffer layer that are close to each other. The first sound-insulating layer is located below the second sound-insulating layer. A turbulence cavity is located between the first and second sound-insulating layers, and multiple turbulence columns are located inside the turbulence cavity. This invention, by utilizing the first and second sound-insulating layers, can absorb and reduce noise. Furthermore, by utilizing the multiple turbulence columns and multiple turbulence holes, sound waves can be refracted irregularly multiple times, thereby achieving the purpose of noise reduction.

[0004] However, the above-mentioned device still has shortcomings:

[0005] The size of a vehicle battery varies depending on the vehicle model, which makes it difficult to properly secure the acoustic pack to the battery. As a result, the acoustic pack cannot function properly, and the noise can affect the physical and mental health of the driver. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an acoustic package for automotive motors with an adjustable locking buckle, addressing the issue that the size of vehicle batteries varies with different vehicle models, making it difficult to secure the acoustic package to the battery properly. This results in the acoustic package failing to function, and noise affecting the driver's physical and mental health.

[0007] To achieve the above objectives, this utility model proposes an automotive motor acoustic package with an adjustable locking buckle, comprising an upper protective layer, a lower protective layer below the upper protective layer, a leather outer shell fixedly connected to the bottom of the lower protective layer, an inner groove formed at one end of the leather outer shell, an inner leather strip slidably connected inside the inner groove, a first buckle fixedly connected to the other end of the leather outer shell, one end of the inner leather strip slidably connected inside the inner groove, a plurality of fixing holes formed on the surface of the inner leather strip, and a second buckle fixedly connected to the other end of the inner leather strip.

[0008] Preferably, a fixing nut is connected through the side wall of the leather case shell, a nut is threadedly connected to the side wall of the fixing nut, and one end of the fixing nut, which is located in the inner groove, is connected through the fixing hole.

[0009] Preferably, a sponge pad is fixedly connected to the bottom of the upper protective layer, and a soft rubber pad is fixedly connected to the top of the lower protective layer.

[0010] Preferably, a buffer wave pad is provided between the sponge pad and the soft rubber pad, and the sidewall of the buffer wave pad is connected with reinforcing ribs.

[0011] Preferably, a plurality of springs are fixedly connected to the top of the soft rubber pad.

[0012] Preferably, an outer shell is fixedly connected to the outside of the upper protective layer.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By using the inner strip and outer shell of the leather sleeve, when installing the entire device, first drive the inner strip of the leather sleeve to slide in the inner groove, move it to the appropriate position, then insert the fixing nut into the fixing hole, and at the same time rotate the nut to fix the fixing nut. Finally, snap the second buckle and the first buckle together, so that it can cover the car motor.

[0015] The advantages of this design are that the device can better adapt to motors of different sizes. Secondly, the snap-on connection method also makes it easier to install and replace. The fact that the device can adapt to motors of different sizes means that this acoustic package has a wider range of applicability. There is no need to design an acoustic package separately for each motor size, which reduces design and manufacturing costs. This design can also meet the needs of different car models and different motor configurations in the market, thereby improving the product's market competitiveness.

[0016] Secondly, the snap-on connection method is more convenient and faster than traditional fixing methods such as bolts and welding. It reduces the number of steps and tools required in the installation process, improves installation efficiency, and also allows for easier disassembly and reinstallation of the acoustic package during vehicle use, facilitating maintenance and replacement.
