Description

Technical Field

[0001] The present application relates to the technical field of automobile air-conditioning dampers, and in particular to an automobile air-conditioning damper structure with a noise reduction function. Background Art

[0002] When driving a car in the summer, car owners will basically turn on the air conditioner. At this time, the car is in a closed space. Although the noise outside the car will be greatly reduced, when the air conditioner gear is turned on higher, the noise inside the car will still become relatively loud, thus affecting the comfort of the people in the car. Utility Model Content

[0003] In order to improve the comfort of the occupants in the vehicle, the present application provides a vehicle air conditioning damper structure with a noise reduction function, which adopts the following technical solutions:

[0004] An automobile air conditioner damper structure with noise reduction function, comprising:

[0005] Air conditioning vents;

[0006] A noise reduction bottom plate is fixedly connected to the air outlet of the air conditioner to form a noise reduction cavity, and both ends of the noise reduction cavity are connected to the air outlet of the air conditioner;

[0007] A noise reduction baffle is arranged in the noise reduction cavity at intervals and is fixedly connected to the noise reduction bottom plate and the air outlet of the air conditioner, and a ventilation hole is opened on the noise reduction baffle;

[0008] The sound-absorbing cotton is fixedly connected to the noise reduction bottom plate and the noise reduction partition plate.

[0009] By adopting the above technical solution, the air-conditioning wind enters the noise reduction cavity, flows in the noise reduction cavity through the ventilation holes, and enters the air-conditioning outlet and is blown out; the air-conditioning wind resonates with the air already existing inside the noise reduction cavity, and the sound energy carried is consumed between two adjacent noise reduction partitions, and the sound-absorbing cotton further absorbs the noise, thereby reducing the noise of the air-conditioning wind and improving the comfort of people in the car.

[0010] Optionally, the air conditioning damper structure further includes:

[0011] A silencer pipe is connected to the noise reduction cavity; the silencer pipe is provided with a plurality of air inlet holes;

[0012] A muffler shell is fixedly connected to the muffler pipe, and a plurality of air outlets connected to the air inlet are provided on the muffler shell; the muffler shell can be connected to the blower;

[0013] The air regulating component is installed in the muffler shell and is used to adjust the number of the air outlet holes according to the wind force.

[0014] By adopting the above technical solution, when the wind force is strong, the air regulating component can increase the number of air outlet holes. Although the wind force is relatively strong and the noise generated is relatively loud, the noise will first be consumed by the silencer shell and the air regulating component, then by the silencer pipe, and finally enter the noise reduction cavity for further consumption, thereby further reducing the noise.

[0015] Optionally, the air regulating component includes:

[0016] A wind blocking plate, rotatably connected to the muffler shell;

[0017] An air consumption plate, slidably connected in the muffler shell;

[0018] A return spring has one end connected to the inner wall of one end of the muffler shell, and the other end connected to the air consumption plate.

[0019] By adopting the above technical solution, the wind baffle is suitable for small and medium wind speeds. When the wind speed exceeds the small and medium wind speeds, the air-conditioning wind will drive the wind baffle to rotate, and part of the air-conditioning wind will push the wind consumption plate to move, and the noise will be further consumed.

[0020] Optionally, grooves are provided on the inner wall of the silencer shell, the wind blocking plate and the wind dissipation plate.

[0021] By adopting the above technical solution, noise is further reduced.

[0022] Optionally, the air conditioning damper structure further includes:

[0023] A counter-punch shell is fixedly connected to the muffler shell and is provided with a counter-punch hole, wherein the counter-punch hole is communicated with the muffler shell;

[0024] The hedging component is installed in the hedging shell to achieve wind hedging.

[0025] Optionally, the hedging component includes:

[0026] A counter plate, fixedly connected to the counter shell and forming a flow cavity with the inner wall of the counter shell;

[0027] A collecting plate is fixedly connected in the counter-shell, and forms a counter-cavity with the counter-plate, and forms a collecting cavity with the inner wall of the counter-shell; one end of the flow cavity can be connected to the blower, and the other end is respectively connected to the collecting cavity and the counter-cavity.

[0028] By adopting the above technical solution, the sound energy carried by the noise can be offset, thereby further consuming the noise.

[0029] Optionally, the air conditioning damper structure further includes:

[0030] The integrated shell covers the counter shell, the silencer shell and the silencer pipe, and is fixedly connected to the noise reduction bottom plate.

[0031] In summary, the present application has at least the following beneficial effects:

[0032] 1. The purpose of setting up the noise reduction bottom plate, noise reduction partition and sound-absorbing cotton is to make the air from the air conditioner resonate with the air already existing inside the noise reduction cavity. The sound energy carried is consumed between two adjacent noise reduction partitions, and the sound-absorbing cotton further absorbs the noise, thereby reducing the noise of the air conditioner and improving the comfort of the people in the car.

[0033] 2. The purpose of setting the silencer pipe, silencer shell, wind block plate, wind consumption plate and return spring is that the wind block plate is suitable for small and medium wind force. When the wind force exceeds the small and medium wind force, the air conditioning wind will drive the wind block plate to rotate, and part of the air conditioning wind will push the wind consumption plate to move, and the noise will be further consumed.

[0034] 3. The purpose of opening grooves on the inner wall of the silencer shell, the wind blocking plate and the wind consumption plate is to further consume noise. BRIEF DESCRIPTION OF THE DRAWINGS

The air blocking plate 331 is rotatably connected to the muffler shell 320, the air consumption plate 332 is slidably connected to the muffler shell 320, one end of the return spring 333 is fixedly connected to the inner wall of one end of the muffler shell 320, and the other end is fixedly connected to the air consumption plate 332. The air blocking plate 331 is usually set at a medium wind force, that is, at the air outlet corresponding to the medium wind force; after the wind force exceeds the medium wind force, the air blocking plate 331 will rotate, so that the air conditioning wind continues to move in the muffler shell 320.

[0043] It should be noted that the grooves 321 may be provided on the inner wall of the muffler shell 320 , the wind blocking plate 331 and the wind consumption plate 332 .

A counter-shell assembly 410 is installed in the counter-shell 400. The counter-shell assembly 410 may include a counter-shell plate 411 and a current collecting plate 412. The counter-shell plate 411 is fixedly connected to the counter-shell 400, and forms a flow cavity 415 with the inner wall of the counter-shell 400.

The sound-absorbing cotton is also fixedly connected in the integrated housing 500.

[0046] The implementation principle of this embodiment is:

[0047] The air-conditioning wind enters the counter-shock shell 400, part of it enters the collecting chamber 414, and part of it enters the counter-shock chamber 413. The air-conditioning wind entering the counter-shock chamber 413 will enter the collecting chamber 414 again, thereby offsetting the air-conditioning wind initially entering the collecting chamber 414, and consuming the noise for the first time. The air-conditioning wind in the collecting chamber 414 enters the silencer shell 320 through the counter-shock hole and is consumed for the second time. The air-conditioning wind enters the silencer pipe 310 through the air outlet hole, and finally enters the noise reduction cavity 220, and is consumed for the third time.
