[0002] The problem of high noise caused by air conditioner compressor vibration is mainly caused by the mechanical movement inside the compressor and the flow of refrigerant. The design and manufacturing process of the compressor have a direct impact on its vibration and noise. As the "heart" of the air conditioner, the noise generated by the compressor during operation is inevitable.

[0003] In order to reduce the noise during the operation of the parking air conditioner, it is necessary to perform good vibration reduction and fixation on the compressor. A compressor vibration reduction structure and a parking air conditioner with Chinese patent publication number CN218966629U include a mounting plate, a suspension plate is arranged on the mounting plate, an elastic component is tightly arranged 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 vibration reduction and noise reduction of the compressor, and helps to ensure the compactness of the compressor installation.

[0004] However, in this application, the form of buffering vibration by spring has certain limitations, and the compressor body cannot be quickly stabilized. Therefore, this application provides a compressor vibration reduction fixing device, a parking air conditioner and a control method to solve the installation and vibration reduction problem of the compressor body in the prior art. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a compressor vibration reduction fixing device, a parking air conditioner and a control method.

[0006] The technical solution adopted by the present invention to solve the technical problem is: a compressor vibration reduction fixing device, comprising two fixing rings and a control part, wherein the fixing ring is detachably connected to the compressor body, the control part comprises a generator, a connecting plate and a shock absorbing box, the connecting plate is connected between the two fixing rings, and the shock absorbing box is connected between the connecting plate and the generator;

[0007] A transmission shaft, an output shaft and a connecting shaft are arranged inside the shock absorber box, the transmission shaft is connected to the connecting plate, the output shaft is connected to the generator, the transmission shaft is provided with a first transmission gear, the connecting shaft is provided with a second transmission gear and a third transmission gear, the output shaft is connected to a fourth transmission gear, the first transmission gear is meshedly connected to the second transmission gear, and the third transmission gear is meshedly connected to the fourth transmission gear.

[0008] As an optimization, the transmission shaft is coaxially arranged with the output shaft, the transmission shaft is parallelly arranged with the connecting shaft, and the connecting shaft is rotatably connected with the outer shell of the shock absorber box.

[0009] As an optimization, a correction gear is provided inside the shock absorber box. The correction gear is located on the side of the third transmission gear away from the fourth transmission gear. The correction gear is meshingly connected with the third transmission gear. When the meshing direction of the third transmission gear and the fourth transmission gear changes, the correction gear is used to drive the third transmission gear to rotate in the opposite direction, thereby promoting rapid meshing of the third transmission gear and the fourth transmission gear. A correction motor is connected to the axis of the correction gear.

[0010] As an optimization, the diameter of the first transmission gear is larger than the diameter of the second transmission gear, and the diameter of the third transmission gear is larger than the diameter of the fourth transmission gear.

[0011] As an optimization, the ratio of the diameter length of the first transmission gear to the diameter length of the second transmission gear is not less than 3:1; the ratio of the diameter of the third transmission gear to the diameter of the fourth transmission gear is equal to the ratio of the diameter length of the first transmission gear to the diameter length of the second transmission gear.

[0012] As an optimization, a detection block is provided on the outside of the compressor body, a detection arm is provided on the outside of the shock absorber box, the outer end of the detection arm is connected to a distance sensor, the detection end of the distance sensor is arranged toward the detection block, and the length direction of the detection arm is perpendicular to the axial direction of the transmission shaft.

[0013] A parking air conditioner comprises any one of the compressor damping and fixing devices described above.

[0014] A control method for a compressor vibration reduction fixing device detects the distance change between a detection arm and a detection block through a distance sensor. When the distance begins to increase or decrease, a correction motor drives a correction gear to rotate, and the correction gear drives a third transmission gear and a second transmission gear to rotate in the opposite direction, so that the second transmission gear and the first transmission gear are quickly meshed.

[0015] As an optimization, when the compressor body swings, the compressor body drives the transmission gear set to rotate through the transmission shaft.

[0017] The present invention provides a compressor vibration reduction fixing device, a parking air conditioner and a control method, which have the following advantages:

[0018] The present application connects the compressor body through a fixing ring, and connects the fixing ring through a control part. When the compressor body generates vibration during operation, the vibration direction and amplitude of the compressor body are detected through a distance sensor, and the amplitude of the vibration is offset through a generator and a shock-absorbing box, thereby reducing the vibration of the equipment.

[0019] The compressor body and the generator are connected through a shock absorber box. The gear set inside the shock absorber box can amplify the mechanical movement of the compressor body.

DETAILED DESCRIPTION

[0026] 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.

[0027] like Figure 1-Figure 5As shown, a compressor vibration reduction fixing device comprises two fixing rings 1 and a control part, wherein the fixing ring 1 is detachably connected to the compressor body, the control part comprises a generator 2, a connecting plate 3 and a shock absorbing box 4, the connecting plate 3 is connected between the two fixing rings 1, and the shock absorbing box 4 is connected between the connecting plate 3 and the generator 2;

[0028] The interior of the shock absorber box 4 is provided with a transmission shaft 5, an output shaft 6 and a connecting shaft 7, the transmission shaft 5 is connected to the connecting plate 3, the output shaft 6 is connected to the generator 2, the transmission shaft 5 is provided with a first transmission gear 8, the connecting shaft 7 is provided with a second transmission gear 9 and a third transmission gear 10, the output shaft 6 is connected to a fourth transmission gear 11, the first transmission gear 8 is meshedly connected to the second transmission gear 9, and the third transmission gear 10 is meshedly connected to the fourth transmission gear 11.

[0029] A fixing column is arranged outside the compressor body, and a fixing ring 1 is fixed by the fixing column. Two adjacent fixing rings 1 are connected with two oppositely arranged control parts. When the compressor body swings, the swinging force of the compressor body is transmitted outwards through the control part, thereby increasing the swinging pressure of the compressor body, suppressing the movement of the compressor body, reducing the swinging amplitude of the compressor body, and reducing equipment noise.

[0030] The movement of the compressor body is transmitted outward through the first transmission gear 8, the swing amplitude of the compressor body is amplified by the second transmission gear 9, and then further amplified to the fourth transmission gear 11 by the third transmission gear 10. When the swing angle of the compressor body is 2°, after two amplifications, the rotation angle of the fourth transmission gear 11 may be ten times or even a hundred times. Therefore, this transmission direction is a labor-intensive gear set, which can effectively improve the power generation efficiency of the generator 2 and suppress the movement of the compressor body.

[0031] like Figure 4 and Figure 5 As shown, the transmission shaft 5 is coaxially arranged with the output shaft 6 , the transmission shaft 5 is arranged parallel to the connecting shaft 7 , and the connecting shaft 7 is rotatably connected with the outer shell of the shock absorber box 4 .

[0032] The transmission shaft 5 and the output shaft 6 can also be arranged in parallel. When the transmission shaft 5 and the output shaft 6 are arranged coaxially, the transmission gear set occupies less space. In order to ensure the stability of the transmission shaft 5 and the output shaft 6, a support platform can be arranged inside the shock absorber box 4, so that the transmission shaft 5 and the output shaft 6 are rotatably connected to the support platform, so as to ensure that the transmission shaft 5 and the output shaft 6 are stable under force.

[0033] like Figure 5As shown, a correction gear 12 is provided inside the shock absorber box 4, and the correction gear 12 is located on the side of the third transmission gear 10 away from the fourth transmission gear 11. The correction gear 12 is meshed and connected with the third transmission gear 10. When the meshing direction of the third transmission gear 10 and the fourth transmission gear 11 changes, the correction gear 12 is used to drive the third transmission gear 10 to rotate in the opposite direction, thereby promoting the third transmission gear 10 to mesh with the fourth transmission gear 11 quickly.

[0034] The axis of the correction gear 12 is connected to the correction motor. When the distance sensor 15 detects that the distance begins to increase or decrease, it indicates that the compressor body begins to swing in the opposite direction. The correction gear 12 drives the third transmission gear 10 and the second transmission gear 9 to rotate in the opposite direction, so that the second transmission gear 9 and the first transmission gear 8 are quickly meshed, reducing the meshing gap.

[0035] like Figure 4 and Figure 5 As shown, the diameter of the first transmission gear 8 is greater than the diameter of the second transmission gear 9 , and the diameter of the third transmission gear 10 is greater than the diameter of the fourth transmission gear 11 .

[0036] like Figure 4 and Figure 5 As shown, the ratio of the diameter length of the first transmission gear 8 to the diameter length of the second transmission gear 9 is not less than 3:1; the ratio of the diameter of the third transmission gear 10 to the diameter of the fourth transmission gear 11 is equal to the ratio of the diameter length of the first transmission gear 8 to the diameter length of the second transmission gear 9.

[0037] Correspondingly, the diameter length of the first transmission gear 8 and the diameter length of the second transmission gear 9 can be 5:1 or 10:1. When the ratio is 10:1, if the first transmission gear 8 rotates 36°, the second transmission gear 9 can transmit one circle, and the corresponding third transmission gear 10 rotates one circle synchronously, and the third transmission gear 10 can mesh and drive the fourth transmission gear 11 to rotate 10 circles. Even if the compressor body drives the first transmission gear 8 to swing a small angle, the swing amplitude can be amplified by the transmission gear set, and then the swing direction and swing amplitude of the compressor body can be more accurately judged by the rotation angle of the generator 2.

[0038] like Figure 4 As shown, a detection block 13 is provided on the outside of the compressor body, a detection arm 14 is provided on the outside of the shock absorber box 4, the outer end of the detection arm 14 is connected to a distance sensor 15, the detection end of the distance sensor 15 is arranged toward the detection block 13, and the length direction of the detection arm 14 is perpendicular to the axial direction of the transmission shaft 5.

[0039] The present solution also includes a controller, the position of which is set by the staff according to actual conditions during operation. The controller is used to control the electrical devices used in the present solution, including but not limited to sensors, motors, telescopic rods, water pumps, solenoid valves, heating wires, heat pumps, display screens, computer input devices, switch buttons, communication equipment, lights, speakers and microphones; the controller is an Intel processor, an AMD processor, a PLC controller, an ARM processor or a single-chip microcomputer, and the supporting components include a motherboard, a memory stick, a storage medium and a power supply, and the power supply is AC or a lithium battery; when a display screen is provided, a display card is also provided.

[0040] The distance sensor 15 is connected to the controller via a line or a signal. When the distance sensor 15 detects a change in the distance signal, the distance signal is transmitted to the controller, and the controller controls the operation of the correction motor.

[0041] When the device is used, the compressor body can be fixed. When the compressor body vibrates, the compressor body drives the connecting plate 3 to rotate. The connecting plate 3 is driven by the transmission shaft 5 to drive the first transmission gear 8 to rotate.

[0042] The first transmission gear 8 is meshed with the second transmission gear 9, and drives the third transmission gear 10 to rotate through the connecting shaft 7, and the third transmission gear 10 drives the fourth transmission gear 11 to rotate, thereby enabling the generator 2 to generate electricity. This process is a laborious gear process, which can effectively increase the resistance of the compressor body when it swings, reduce the maximum amplitude of the compressor body's swing, and at the same time can recover the energy generated by the vibration of the equipment, killing two birds with one stone.

[0043] A parking air conditioner comprises any one of the compressor damping and fixing devices described above.

[0044] A control method is used to control the compressor shock absorbing fixing device described in any one of the above items, wherein the distance change between the detection arm 14 and the detection block 13 is detected by the distance sensor 15. When the distance begins to increase or decrease, the correction motor drives the correction gear 12 to rotate, and the correction gear 12 drives the third transmission gear 10 and the second transmission gear 9 to rotate in the opposite direction, so that the second transmission gear 9 and the first transmission gear 8 are quickly engaged.

[0045] When the compressor body swings, the compressor body drives the transmission gear set to rotate through the transmission shaft 5. The transmission gear set is a labor-intensive gear set, which can amplify the mechanical movement amplitude of the compression body through the shock-absorbing box 4, thereby promoting the operation of the generator 2 to generate electricity.

[0046] The transmission gear set includes a first transmission gear 8 , a second transmission gear 9 , a third transmission gear 10 and a fourth transmission gear 11 .

[0047] The correction motor is connected to the controller. When the vibration direction of the compressor body changes, the correction motor immediately runs in the reverse direction, driving the correction gear 12 to rotate in the reverse direction, so that the rotation of the second transmission gear 9 changes rapidly in the reverse direction, so that the second transmission gear 9 and the first transmission gear 8 can quickly and completely mesh with each other to avoid the generation of meshing gaps.

[0048] There will be a certain gap when the gears are meshing, especially when the diameter difference between the two meshing gears is large. Changing the rotation direction of the gears may affect the good meshing between the gears. Therefore, the direction of the follower gear is adjusted in time by the correction motor and the correction gear 12 to avoid the gear from getting stuck.

[0049] Correspondingly, the generator 2 of the present application can also be replaced by a drive motor. When the drive motor is installed, the drive motor can be transmitted in the direction of the compressor body through the shock absorber box 4. The drive gear set in the transmission direction is a labor-saving gear set. The labor-saving gear set can reduce the mechanical movement amplitude of the drive motor, that is, when the drive motor rotates one circle or half a circle, the posture of the compressor body can be adjusted more finely, thereby offsetting the swing amplitude of the compressor body and keeping the compressor body in dynamic balance. However, it should be noted that the labor-saving gear set and the above-mentioned labor-intensive gear set will not appear at the same time, and can be selected according to the actual volume and vibration conditions of the compressor body.

[0050] 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. Any compressor vibration reduction fixing device, parking air conditioner and control method that conform to the claims of the present invention and any appropriate changes or modifications made thereto by ordinary technicians in the corresponding technical field shall fall within the patent protection scope of the present invention.
