When the vehicle is parked, waiting or resting, the air conditioner can be powered by the vehicle battery to keep running continuously, and the temperature, humidity, flow rate, etc. of the air in the vehicle can be adjusted and controlled to fully meet the truck driver's needs for comfortable temperature regulation.

[0003] The parking air conditioner is generally connected to the vehicle body through multiple mounting feet. However, when the main air conditioner is running, the vibration of its compressor body will produce strong vibration, causing the parking air conditioner to produce obvious noise when in use, affecting the comfort of using the vehicle's parking air conditioner.

[0004] To solve the above problems, a compressor damping structure and a parking air conditioner with Chinese patent publication number CN218966629U are disclosed, which include a mounting plate, a suspension plate is arranged on the mounting plate, an elastic component is arranged tightly between the suspension plate and the mounting plate, and the middle part of the suspension plate is recessed toward one side of the mounting plate and forms a mounting groove. The application has the effect of achieving damping and noise reduction of the compressor and helping to ensure the compactness of the compressor installation.

[0005] However, in this application, the vibration of the compressor body is buffered only by the spring. Under the action of the spring, the shock absorbing effect of the spring is relatively slow, and the compressor body still vibrates. The buffering effect is not good and there are certain defects in the use process.

[0006] Therefore, the present application provides a compressor noise reduction structure based on a parking air conditioner, which solves the problem of high operating noise of the parking air conditioner compressor in the prior art, improves the shock absorption effect of the compressor, and achieves efficient noise reduction of the compressor.

[0030] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0031] like Figure 1-Figure 8 As shown, a compressor noise reduction structure based on a parking air conditioner includes a compressor body 1, a fixing column 2 is arranged on the outside of the compressor body 1, a shock absorbing part is arranged on the outside of the compressor body 1, and the shock absorbing part includes a fixing frame 3 and a connecting seat 4, and the fixing frame 3 is used to be connected to the vehicle body;

[0032] A plurality of buffer springs 5 ​​are arranged between the fixing frame 3 and the connecting seat 4. The connecting seat 4 includes a connecting portion connected to the compressor body 1 and a buffer seat 7 connected to the fixing frame 3. The fixing column 2 is arranged through the connecting portion. The fixing frame 3 is provided with a buffer portion 6 matched with the buffer seat 7. The buffer portion 6 and the buffer seat 7 are arranged coaxially. When the compressor body 1 vibrates, the buffer portion 6 and the buffer seat 7 can generate relative rotation.

[0033] The connection part and the buffer seat 7 can be fixedly connected or integrally formed. The connection seat 4 is provided with a connection hole, and the fixing column 2 is arranged through the connection hole, and the connection seat 4 and the fixing column 2 cannot move freely. The fixing frame 3 can be fixed to the vehicle body or the outer shell of the parking air conditioner by bolts and other structures.

[0034] The elastic strength of the buffer spring 5 is preferably sufficient to support the weight of the compressor body 1 .

[0035] The buffer seat 7 can rotate relative to the buffer portion 6 to achieve buffering of the vibration of the compressor body 1 and avoid rigid fracture of the shock-absorbing part.

[0036] like Figure 6 As shown, a buffer cavity 8 for accommodating a buffer portion 6 is provided inside the buffer seat 7, the buffer portion 6 is in contact and sealed with the inner wall of the buffer cavity 8, the bottom surface of the buffer cavity 8 is a contact arc, and two opposite side surfaces inside the buffer cavity 8 are guide arcs 9, and the centers of the two guide arcs 9 coincide with the midpoints of the contact arcs;

[0037] Two opposite sides of the buffer portion 6 are guide sections, and the guide sections are arranged in close contact with the guide arc 9. A contact section 10 is located between the two guide sections, and the contact section 10 is arranged opposite to the contact arc.

[0038] The buffer portion 6 and the buffer seat 7 are coaxially arranged, and the two can generate relative rotation. Figure 6 For example, when the buffer seat 7 vibrates under the action of the compressor body 1, the upper and lower parts of the buffer seat 7 can swing left and right. When the buffer portion 6 moves, its contact section 10 is always in contact with the contact arc.

[0039] like Figure 6 As shown, the fixing frame 3 is provided with a connecting arm, the outer end of the connecting arm is connected to an I-shaped buffer 11, the interior of the buffer portion 6 is provided with an I-shaped buffer cavity 12, the I-shaped buffer 11 is slidably arranged in the I-shaped buffer cavity 12, the I-shaped buffer 11 can move along the length direction of the I-shaped buffer cavity 12, a connecting channel is provided between the I-shaped buffer cavity 12 and the buffer cavity 8, and the connecting channel and the buffer cavity 8 are filled with hydraulic medium.

[0040] The I-shaped buffer 11 may be rod-shaped. When the I-shaped buffer 11 moves inside the I-shaped buffer cavity 12, the I-shaped buffer 11 will push the hydraulic medium inside the I-shaped buffer cavity 12 into the connecting channel. Under the action of hydraulic pressure, the movement trend of the two can be buffered.

[0041] Correspondingly, in order to further improve the shock absorbing effect of the shock absorbing part, a movable structure in other directions can be set between the connecting arm and the I-shaped buffer 11, so that relative displacement can be generated between the I-shaped buffer 11 and the connecting arm, thereby further improving the shock absorbing ability of the device.

[0042] like Figure 6 As shown, the movable direction of the I-shaped buffer member 11 is perpendicular to the axial direction of the buffer portion 6 , and the two parallel cavities of the I-shaped buffer cavity 12 are isolated and sealed by the I-shaped buffer member 11 .

[0043] The I-shaped buffer member 11 is always located in the I-shaped buffer cavity 12 and can always seal the I-shaped buffer cavity 12 so that the hydraulic medium in the I-shaped buffer cavity 12 will not leak. The hydraulic medium can be hydraulic oil or any other medium that has the functions of buffering, lubrication, fluidity and can be used safely.

[0044] like Figure 6 As shown, the axial direction of the buffer portion 6 is perpendicular to the axial direction of the buffer spring 5 .

[0045] The buffer portion 6 and the buffer seat 7 can buffer vibration along the axial direction of the compressor body 1 .

[0046] like Figure 6As shown, the communication channel includes a hydraulic channel 13 connected to one end of the I-shaped buffer cavity 12 away from the fixing frame 3 and a communication cavity 14 communicating with the outer end of the hydraulic channel 13 , and the communication cavity 14 is communicated with the buffer cavity body 8 .

[0047] When the I-shaped buffer 11 moves, the I-shaped buffer 11 pushes the hydraulic medium to move into the communication channel. When the hydraulic pressure inside the communication channel increases, the hydraulic medium is pressed into the buffer cavity 8. The hydraulic medium can flow between the buffer cavity 8, the I-shaped buffer cavity 12 and the communication channel, and flows from the high-pressure area to the low-pressure area.

[0048] like Figure 6 As shown, the length of the guide arc 9 is greater than the length of the guide segment, and the radius of the circle where the contact arc is located is greater than the radius of the circle where the contact segment 10 is located.

[0049] The guide section can move along the inner wall of the guide arc 9, and the contact section 10 can rotate relative to the contact arc, so that the connecting seat 4 can swing.

[0050] The noise reduction method includes any one of the compressor noise reduction structures described above. When the compressor body 1 generates vibration, the vibration is transmitted to the connecting seat 4 through the fixing column 2, and the vibration is buffered by the buffer structure and the buffer spring 5 between the connecting seat 4 and the fixing frame 3.

[0051] The buffer structure includes a buffer seat 7 and a buffer part 6. When the compressor body 1 vibrates, the compressor body 1 transmits the vibration to the connecting seat 4 through the fixed column 2. The buffer seat 7 vibrates under the vibration of the compressor body 1. The buffer seat 7 can rotate relative to the buffer part 6. The relative movement between the buffer part 6 and the buffer seat 7 is buffered by the hydraulic medium, thereby reducing the vibration of the compressor body 1.

[0052] When the compressor body 1 is running, the compressor body 1 does not directly contact the vehicle body and other workpieces, and the vibration generated by its operation is transmitted to the outside through the connecting seat 4;

[0053] The vibration of the connecting seat 4 is initially buffered by the buffer spring 5 to reduce the vibration amplitude of the compressor body 1;

[0054] When the compressor drives the connecting seat 4 to vibrate, the connecting seat 4 drives the two buffer seats 7 to vibrate, so that the buffer portion 6 and the buffer seat 7 can generate relative rotation, thereby buffering the vibration in the lateral and oblique directions;

[0055] Furthermore, since the fixing frame 3 is fixedly arranged, when the buffer seat 7 generates longitudinal vibration, a relative displacement occurs between the buffer portion 6 and the I-shaped buffer member 11, so that the hydraulic medium in the I-shaped buffer cavity 12 is pressed into the hydraulic channel 13, and the movement of the I-shaped buffer member 11 is buffered by the hydraulic medium, thereby reducing the intensity and amplitude of the vibration;

[0056] When the hydraulic pressure inside the hydraulic channel 13 increases, the excess hydraulic medium is pressed into the connecting cavity 14. The connecting cavity 14 can be empty in the initial state. When the buffer part 6 and the buffer cavity 8 rotate relative to each other, the hydraulic medium inside the buffer cavity 8 on the squeezed side can also be pressed into the connecting cavity 14, so that the buffer part 6 has a certain moving space. At the same time, the excess hydraulic medium can also be pressed into the buffer cavity 8 on the other side.

[0057] The above-mentioned specific embodiments are only specific cases of the present invention. The patent protection scope of the present invention includes but is not limited to the product form and style of the above-mentioned specific embodiments.
