Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to an automotive air conditioning noise reduction device. Background Technology

[0002] Noise reduction in automotive air conditioning systems is of great significance. For drivers and passengers, it significantly improves in-car comfort. The enclosed space of a car means that loud air conditioning noise can interfere with conversation, rest, and entertainment. A quiet environment allows passengers to relax and helps drivers concentrate, reducing external distractions and ensuring driving safety. From the vehicle's perspective, noise reduction reduces vibration during air conditioning operation. Noise is often accompanied by vibration, and prolonged vibration can loosen connections and accelerate wear of other vehicle components. Reducing noise extends the overall lifespan of the vehicle and lowers maintenance costs. Furthermore, in the highly competitive automotive market, low-noise air conditioning enhances a vehicle's market competitiveness and meets consumers' demands for comfort and quietness.

[0003] Currently, wrapping the air conditioning ducts with sound-absorbing cotton is a common practice in noise reduction for automotive parts. To ensure a secure fit, adhesive is typically used. While this method is simple, it complicates subsequent replacement. The adhesive creates a tight bond between the cotton and the duct, requiring careful handling to avoid damaging the pipes when replacing the cotton. Cleaning away residual adhesive is also tedious, making the overall replacement process relatively inconvenient. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a noise reduction device for automotive air conditioning systems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A noise reduction device for automotive air conditioning includes a rubber pad with a sound insulation layer inside. Multiple sets of belts are connected to the rubber pad, and multiple sets of clips are connected to each of the multiple sets of belts. Multiple sets of clip holes are opened on the rubber pad, and the multiple sets of clips are respectively inserted into the corresponding clip holes.

[0007] Preferably, the rubber pad is connected to multiple sets of hooks, which are equidistantly distributed on the rubber pad and are in contact with the sound insulation layer.

[0008] Preferably, the rubber pad has multiple sets of through holes.

[0009] Preferably, a conduit runs through the sound insulation layer.

[0010] Preferably, the outer surface of the rubber pad is provided with a wear-resistant coating, which can effectively reduce the wear of the rubber pad caused by friction with surrounding parts during vehicle operation and extend the service life of the noise reduction device.

[0011] Preferably, the belt body, the locking block, and the rubber pad are all made of the same material.

[0012] Preferably, the shape of the card block is adapted to the shape of the card hole.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Through the cooperation of the rubber pad, belt, clips, and locking holes, after the sound insulation layer is wrapped around the pipeline, the rubber pad can be wrapped around the outside of the sound insulation layer. The clips on the belt connect to the locking holes at different positions on the rubber pad to bind and fix the rubber pad to the sound insulation layer. This method utilizes the elasticity and flexibility of the rubber pad to tightly conform to the shape of the pipeline, preventing the sound insulation layer from shifting due to vibrations and bumps during vehicle operation, ensuring continuous and effective noise reduction. Furthermore, the tightness of the binding can be flexibly adjusted according to the actual situation of the pipeline, further improving stability. In terms of replacement and maintenance, compared to glue fixation, this clip and locking hole connection method is more convenient. There is no need to deal with glue residue, and there is no need to worry about damaging the pipeline. The rubber pad and sound insulation layer can be easily removed by unfastening the clips.

[0015] 2. Through the interaction between the rubber pad and the hook, and by utilizing the contact between the hook and the sound insulation layer at the rubber pad, the hook can embed itself into the sound insulation layer and work in conjunction with the belt to secure the sound insulation layer from multiple dimensions. In the complex vibration environment of a vehicle, relying solely on the belt may not be able to completely restrict the slight displacement of the sound insulation layer. The hook effectively compensates for this deficiency, greatly reducing the possibility of the sound insulation layer shifting and ensuring its stable attachment to the pipeline, thus continuously exerting its noise reduction effect.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5 An automotive air conditioning noise reduction device includes a rubber pad 1, inside which a sound insulation layer 2 is placed. The sound insulation layer 2 is typically made of materials with good sound absorption properties, such as sound-absorbing cotton or sound insulation felt, which can effectively absorb and block noise generated by automotive air conditioning pipes. Placing the sound insulation layer 2 inside the rubber pad 1 forms a preliminary sound barrier. Multiple sets of straps 3 are connected to the rubber pad 1, and multiple sets of clips 4 are connected to each of the straps 3. Multiple sets of locking holes 5 are provided on the rubber pad 1, and the multiple sets of clips 4 are inserted into corresponding locking holes 5. In actual installation, after the sound insulation layer 2 is wrapped around the pipe 8, the rubber pad 1 is wrapped around the sound insulation layer 2. By inserting the clips 4 from the straps 3 into the locking holes 5 at different positions on the rubber pad 1, the rubber pad 1 and the sound insulation layer 2 can be bound and fixed. This design has many advantages: firstly, the elasticity and flexibility of the rubber pad 1 allow it to closely conform to the shape of the pipe 8, whether it is round, square, or other irregularly shaped pipes. During vehicle operation, the rubber pad 1 tightly wraps around the sound insulation layer 2 to prevent displacement in the face of vibration and bumps, thus ensuring a continuous and effective noise reduction effect. Furthermore, the tightness of the binding can be flexibly adjusted by inserting the clip 4 into different positions of the clip hole 5. For pipes 8 of different diameters, or in different installation environments, optimization and adjustments can be made according to actual needs, further improving the stability of the entire noise reduction device.

[0024] In this embodiment, multiple sets of hooks 6 are connected to the rubber pad 1. Under the complex vibration environment of a vehicle, relying solely on the binding of the strap 3 may not be able to completely restrict the slight displacement of the sound insulation layer 2. However, the hooks 6 can be embedded in the sound insulation layer 2, forming a multi-dimensional fixation method with the binding of the strap 3. The hooks 6 act like small anchor points, tightly gripping the sound insulation layer 2, effectively compensating for the inadequacy of the binding of the strap 3, greatly reducing the possibility of displacement of the sound insulation layer 2, ensuring its stable attachment to the pipe 8, and continuously exerting its noise reduction effect. Multiple sets of hooks 6 are equidistantly distributed at the rubber pad 1, and multiple sets of hooks 6 are in contact with the sound insulation layer 2. Multiple sets of through holes 7 are opened at the rubber pad 1, and the through holes 7 play a certain role in heat dissipation. During vehicle operation, the air conditioning pipes generate heat, and some of the heat will be transferred to the rubber pad 1 and the sound insulation layer 2. The through-hole 7 promotes air circulation and accelerates heat dissipation, preventing heat buildup that could lead to aging of the rubber pad 1 and performance degradation of the sound insulation layer 2, thus extending the lifespan of the entire noise reduction device. A pipe 8 runs through the sound insulation layer 2, and the outer surface of the rubber pad 1 is coated with a wear-resistant material, effectively reducing wear caused by friction with surrounding components during vehicle operation and extending the lifespan of the noise reduction device. The belt body 3, the locking block 4, and the rubber pad 1 are all made of the same material, ensuring the consistency and compatibility of the entire fixing system. The use of the same material ensures that the physical and chemical properties of each component match, avoiding problems such as different expansion coefficients and corrosion caused by material differences, thus improving the reliability and stability of the entire device. Furthermore, the shape of the locking block 4 matches the locking hole 5, ensuring a tight fit. After insertion and fixing, the locking block 4 is firmly locked in the locking hole 5, preventing loosening or detachment, further enhancing the fixing effect.

[0025] The working principle of this embodiment is as follows: When in use, the sound insulation layer 2 is wrapped around the pipe 8. After wrapping, the rubber pad 1 is wrapped around the sound insulation layer 2. At this time, the hook 6 at the rubber pad 1 will contact the sound insulation layer 2 to connect the rubber pad 1 and the sound insulation layer 2. Subsequently, the strap 3 drives the locking block 4 to connect with the locking holes 5 at different positions of the rubber pad 1, so that the rubber pad 1 can fix the sound insulation layer 2 on the pipe 8 for noise reduction. When the sound insulation layer 2 needs to be replaced, the locking block 4 is separated from the locking hole 5, and the rubber pad 1 can be unfolded for replacement.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
