Description

Technical Field

[0001] This invention relates to the field of parking air conditioning, and more specifically, to an installation structure and control method for a parking air conditioning system. Background Technology

[0002] Parking air conditioners are air conditioners used in trucks and other heavy vehicles when they are stationary, and are independent of the original vehicle's air conditioning system. Parking air conditioners use the original vehicle battery or an auxiliary battery for power, bypassing the original engine. This saves fuel, reduces engine exhaust pollution, and provides a comfortable driving or resting environment for occupants, minimizing the impact of engine idling on the vehicle's lifespan. Therefore, parking air conditioners have become popular with many truck and logistics vehicle drivers, leading to a continuous increase in sales. Currently, 90% of parking air conditioners sold on the market are split-type. Split-type parking air conditioners consist of an outdoor unit and an indoor unit, connected by pipes for refrigerant transport and return. Typically, the indoor unit is installed in the cab, while the outdoor unit is mounted directly outside the cab using a mounting bracket.

[0003] The prior art patent application CN201920265292.X discloses an installation structure for a parking air conditioner. The parking air conditioner includes an indoor unit and an outdoor unit, as well as a bracket, a glass window, and a sealing strip. The glass window is used to be installed in a mounting hole on the driver's cab. The sealing strip is wrapped around the outer edge of the glass window and sandwiched between the inner edge of the mounting hole and the outer edge of the glass window. One end of the bracket is fixedly inserted between the inner edge of the mounting hole and the sealing strip, and the other end of the bracket is fixedly installed together with the outdoor unit. The indoor unit is fixedly installed on the outdoor unit and is connected to it. The indoor unit and the outdoor unit are located on opposite sides of the glass window. While this patent achieves holeless installation of the parking air conditioner in the driver's cab, using mounting holes in the glass window to fix the bracket and outdoor unit makes the outdoor unit's installation unstable. During driving, it is very likely to fall off the vehicle due to severe bumps. In addition, simply fixing the outdoor unit to the driver's cab with rigid structures such as screws has poor vibration damping performance. As a result, the outdoor unit will vibrate and generate noise due to vehicle bumps and swaying during driving. Moreover, long-term operation under shaking conditions will also accelerate the damage of its internal components.

[0004] How to design an installation structure for a parking air conditioner that ensures the outdoor unit is securely installed and has good vibration damping performance is a problem that urgently needs to be solved in the field of parking air conditioners. Summary of the Invention

[0005] In view of this, the present invention aims to propose an installation structure and control method for a parking air conditioner to solve the problems of unstable installation and poor shock absorption performance of the outdoor unit in the prior art.

[0006] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0007] An installation structure for a parking air conditioner is disclosed. The installation structure includes a mounting bracket, a mounting cover, and a gas shock absorber. The mounting bracket is mounted on the driver's cab, and the outdoor unit is installed in a cavity formed by the mounting bracket. The mounting cover is disposed on the outside of the mounting bracket and connected to the driver's cab. The gas shock absorber includes a primary gas shock absorber and a secondary gas shock absorber. The primary gas shock absorber is disposed on the mounting bracket, and the secondary gas shock absorber is disposed on the mounting cover. The mounting cover completely covers the mounting bracket and the outdoor unit, increasing their protection and preventing direct impact from external hard objects such as stones, thus increasing safety. Furthermore, the complete coverage prevents the mounting bracket and the outdoor unit from falling off the vehicle. The gas shock absorber, when inflated, not only secures the outdoor unit but also absorbs its vibrations, preventing it from swaying and colliding with the mounting cover and mounting bracket as the transport vehicle moves.

[0008] Furthermore, a shock-absorbing clamping device is provided on the mounting bracket. This device includes an elastic element, a clamping block, and a shock-absorbing block. The elastic element is connected to the mounting bracket, one end of the clamping block is connected to the elastic element, and the other end of the clamping block is connected to the shock-absorbing block. This shock-absorbing clamping device effectively buffers the vibrations caused by vehicle shaking to the outdoor unit, making the connection between the mounting bracket and the outdoor unit less prone to loosening.

[0009] Furthermore, the mounting cover is connected to the outdoor unit.

[0010] Furthermore, the mounting cover has an internal mounting cavity for mounting the mounting bracket and the outdoor unit. A shock-absorbing component is provided on the inner wall of the cover, and the mounting cover is connected to the outdoor unit through the shock-absorbing component.

[0011] Furthermore, the primary gas damping device and the secondary damping device share a single electric air pump, which is connected to the controller of the parking air conditioner.

[0012] Furthermore, the mounting bracket includes a mounting plate, the front panel of which extends into a first fixing part, a second fixing part, and a third fixing part in the direction away from the driver's cab. A receiving cavity is formed between the mounting plate, the first fixing part, the second fixing part, and the third fixing part. The first fixing part and the third fixing part fix the outdoor unit horizontally, and the second fixing part fixes the outdoor unit vertically. The first fixing part, the second fixing part, and the third fixing part limit and fix the outdoor unit in both horizontal and vertical directions, while increasing the contact area between the mounting bracket and the outdoor unit, improving the connection stability of the mounting bracket, preventing the mounting bracket from deforming downwards under the weight of the outdoor unit, and fully ensuring the working stability of the outdoor unit. The shock-absorbing structure on the mounting bracket improves the shock absorption performance of the mounting bracket, reduces the wear and tear on the internal components of the parking air conditioner caused by bumps and swaying during vehicle operation, and reduces abnormal noise during the operation of internal parts.

[0013] Furthermore, a road surface detection device is installed under the vehicle frame, and a controller and alarm are installed on the control panel of the indoor unit. The gas damping device also includes a pressure sensor, and both the pressure sensor and the alarm are electrically connected to the controller.

[0014] A control method for the installation structure of a parking air conditioner is disclosed. The method utilizes the aforementioned installation structure of a parking air conditioner. A road surface monitoring device collects road conditions and transmits the collected data to the parking air conditioner controller via a wireless communication module. The controller can determine the bumpiness of the vehicle body when it passes through the road. If the road bumpiness level is level three, the controller issues inflation commands to both the primary and secondary gas damping devices. If the road bumpiness level is level two, the controller issues inflation commands to the primary gas damping device and deflation commands to the secondary gas damping device. If the road bumpiness level is level one, the controller issues deflation commands to both the primary and secondary gas damping devices.

[0015] Furthermore, the process of controlling the inflation of the gas damping device is as follows:

[0016] S101, Received instruction to inflate the gas damping device;

[0017] S102. Determine whether the vehicle body is in the process of transportation. If yes, execute S103; otherwise, execute S104.

[0018] S103, The controller controls the electric air pump to inflate the gas shock absorber so that the pressure inside the airbag reaches and is maintained within the first preset pressure range.

[0019] S104. The gas damping device remains in its current state.

[0020] Furthermore, the process of controlling the venting of the gas damping device is as follows:

[0021] S201, Received instruction to release gas from the gas damping device;

[0022] S202. Determine whether the pressure inside the airbag of the gas damping device is less than or equal to the second preset pressure. If yes, proceed to S203; otherwise, proceed to S204.

[0023] S203. The gas damping device remains in its current state, and the alarm sounds.

[0024] S204. Depressurize the gas damping device so that the pressure inside the airbag is less than or equal to the second preset pressure.

[0025] This invention proposes an installation structure for a parking air conditioner. Compared with the prior art, the installation structure for a parking air conditioner described in this invention has the following advantages:

[0026] 1) The installation structure of the parking air conditioner described in this invention has a mounting cover that can completely cover the mounting bracket and the outdoor unit, increasing the protection effect of the mounting bracket and the outdoor unit, preventing external hard objects such as stones from directly impacting the mounting bracket and the outdoor unit body, increasing safety, and the complete cover can prevent the mounting bracket and the outdoor unit from falling off the car.

[0027] 2) The installation structure of the parking air conditioner described in this invention, after the gas shock absorber is inflated, not only serves to fix the outdoor unit, but also absorbs the vibration of the outdoor unit, thereby preventing the outdoor unit from shaking with the movement of the transport vehicle and colliding with the mounting cover and mounting bracket.

[0028] 3) The installation structure of the parking air conditioner described in this invention has a shock-absorbing clamping device that effectively buffers the vibration effect of the car shaking on the outdoor unit, making the connection between the mounting bracket and the outdoor unit less prone to loosening.

[0029] 4) The installation structure of the parking air conditioner described in this invention includes a shock-absorbing structure on the mounting bracket, which improves the shock absorption performance of the mounting bracket, reduces the wear and tear on the internal components of the parking air conditioner caused by bumps and swaying during vehicle operation, and reduces abnormal noise during the operation of internal components.

[0030] 5) The installation structure of the parking air conditioner described in this invention, wherein the first fixing part, the second fixing part and the third fixing part are arranged in both horizontal and vertical ways to limit and fix the outdoor unit, while increasing the contact area between the mounting bracket and the outdoor unit, improving the connection stability of the mounting bracket, preventing the mounting bracket from deforming downward under the weight of the outdoor unit, and fully ensuring the working stability of the outdoor unit.

[0031] This invention also proposes a control method for the installation structure of a parking air conditioner. Compared with the prior art, the control method for the installation structure of a parking air conditioner described in this invention has the following advantages:

[0032] 1) The control method for the installation structure of a parking air conditioner described in this invention allows the controller to determine the bumps when the vehicle passes by based on the road conditions collected by the road monitoring device, thereby selecting the number of gas damping devices to use. This control method is relatively accurate, can make full use of the gas damping devices to fix the outdoor unit, and can also absorb the vibration of the outdoor unit, thereby preventing the outdoor unit from shaking with the movement of the transport vehicle and colliding with the mounting cover and mounting bracket.

[0033] 2) In the control method of the installation structure of the parking air conditioner described in this invention, when the vehicle is not in transport, that is, during the parking process, the received inflation command for the gas damping device is an invalid command; when the vehicle is in transport, the received inflation command for the gas damping device is a valid command.

[0034] 3) The control method for the installation structure of a parking air conditioner described in this invention, before deflating the gas damping device, if the pressure inside the airbag of the gas damping device is less than or equal to the second preset pressure, it indicates that the airbag has been deflated, and the airbag of the gas damping device may be leaking. The alarm will sound to remind the driver to repair it in time. Attached Figure Description

[0049] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0050] Example 1

[0051] This embodiment proposes an installation structure for a parking air conditioner, such as... Figure 1-6 As shown, the mounting structure is used to install the outdoor unit 2 of the parking air conditioner, specifically, as follows: Figure 1 and Figure 2 As shown, the mounting structure includes a mounting bracket 1, which includes a mounting plate 11. The front panel of the mounting plate 11 extends in a direction away from the driver's cab 9, with a first fixing part 12, a second fixing part 13, and a third fixing part 15. A receiving cavity is formed between the mounting plate 11, the first fixing part 12, the second fixing part 13, and the third fixing part 15. Figure 6 As shown, the outdoor unit 2 is installed in the receiving cavity formed by the mounting bracket 1. The first fixing part 12 and the third fixing part 15 fix the outdoor unit 2 in the horizontal direction, and the second fixing part 13 fixes the outdoor unit 2 in the vertical direction. A shock-absorbing structure is provided on the mounting bracket 1. The first fixing part 12, the second fixing part 13, and the third fixing part 15 limit and fix the outdoor unit 2 in both horizontal and vertical directions, while increasing the contact area between the mounting bracket 1 and the outdoor unit 2, improving the connection stability of the mounting bracket 1, preventing the mounting bracket 1 from deforming downward under the gravity of the outdoor unit 2, and fully ensuring the working stability of the outdoor unit 2. The shock-absorbing structure provided on the mounting bracket 1 improves the shock absorption performance of the mounting bracket 1, reduces the wear and tear on the internal components of the parking air conditioner due to bumps and swaying during vehicle operation, and reduces abnormal noise during the operation of internal parts.

[0052] The damping structure includes a first damping pad 31 and a second damping pad 32.

[0053] Specifically, such as Figure 4As shown, the rear panel of the mounting plate 11 has a first shock-absorbing pad 31 with a shock-absorbing structure in the direction close to the cab 9. The shape of the first shock-absorbing pad 31 matches that of the mounting plate 11. The installation of the first shock-absorbing pad 31 reduces wear between the mounting bracket 1 and the cab 9.

[0054] More specifically, such as Figure 4 As shown, a fourth mounting hole 311 and a sixth mounting hole 312 are provided on the first shock-absorbing pad 31. The fourth mounting hole 311 and the sixth mounting hole 312 facilitate the installation of the first shock-absorbing pad 31.

[0055] Specifically, such as Figure 1 and Figure 2 As shown, the mounting plate 11 includes a first side plate 111 and a second side plate 112, which are connected by a first connecting plate 113 and a second connecting plate 114. The arrangement of the first connecting plate 113 and the second connecting plate 114 increases the connection area between the mounting frame 1 and the cab 9, and also increases the contact area between the mounting frame 1 and the outdoor unit 2, further improving the connection stability of the mounting frame 1, preventing the mounting frame 1 from deforming downwards under the gravity of the outdoor unit 2, and fully ensuring the working stability of the outdoor unit 2.

[0056] Specifically, such as Figure 1 and Figure 2 As shown, at least one first fixing part 12 is provided on the first side plate 111, and at least one third fixing part 15 is provided on the second side plate 112. The first fixing part 12 and the third fixing part 15 are symmetrically arranged. The symmetrical arrangement of the first fixing part 12 and the third fixing part 15 ensures the balance of the support of the mounting bracket 1 for the outdoor unit 2, and also increases the contact area between the mounting bracket 1 and the outdoor unit 2, further improving the connection stability of the mounting bracket 1, preventing the mounting bracket 1 from deforming downward under the gravity of the outdoor unit 2, and fully ensuring the working stability of the outdoor unit 2.

[0057] Specifically, such as Figure 1 and Figure 2 As shown, a first mounting hole 115 and a third mounting hole 116 are provided on the mounting bracket 1, and the mounting bracket 1 is connected to the cab 9 through the first mounting hole 115 and the third mounting hole 116. The first mounting hole 115 and the third mounting hole 116 facilitate the installation of the mounting bracket 1 on the cab 9.

[0058] More specifically, such as Figure 1 and Figure 4As shown, the mounting bracket 1 is detachably connected to the cab 9. The first mounting hole 115 mates with the fourth mounting hole 311, and the third mounting hole 116 mates with the sixth mounting hole 312. The first connector passes through the first mounting hole 115 and the fourth mounting hole 311 to mount the first side plate 111 onto the cab 9, and the third connector passes through the third mounting hole 116 and the sixth mounting hole 312 to mount the second side plate 112 onto the cab 9.

[0059] Specifically, the first mounting hole 115 is located on the first side plate 111, and the third mounting hole 116 is located on the second side plate 112. The first mounting hole 115 and the third mounting hole 116 are symmetrically arranged. The symmetrical arrangement of the first mounting hole 115 and the third mounting hole 116 ensures the balance of the cab 9 in supporting the mounting bracket 1.

[0060] Specifically, the second fixing part 13 is disposed on the first connecting plate 113, and a second mounting hole 14 is provided on the second fixing part 13. The provision of the second mounting hole 14 facilitates the installation of the outdoor unit 2.

[0061] Specifically, such as Figure 3 As shown, an mounting foot 21 is provided on the outdoor unit 2, and the mounting foot 21 is connected to the second mounting hole 14. The connection between the mounting foot 21 and the second mounting hole 14 facilitates the installation of the bottom of the outdoor unit 2 on the second fixing part 13.

[0062] Specifically, such as Figure 5 As shown, a second shock-absorbing pad 32 with a shock-absorbing structure is provided on the second fixing part 13. The second shock-absorbing pad 32 reduces wear between the mounting bracket 1 and the outdoor unit 2. A fifth mounting hole 321 is provided on the second shock-absorbing pad 32, which mates with the second mounting hole 14. The mate of the fifth mounting hole 321 with the second mounting hole 14 facilitates the installation of the second shock-absorbing pad 32 on the second fixing part 13.

[0063] More specifically, the shock-absorbing structure also includes a third shock-absorbing pad (not shown in the figure). The second connecting plate 114 is provided with the third shock-absorbing pad in the direction away from the cab 9, and the provision of the third shock-absorbing pad further reduces the wear between the mounting bracket 1 and the outdoor unit 2.

[0064] This embodiment proposes a parking air conditioner installation structure. Compared with the prior art, the parking air conditioner installation structure of this invention has the following advantages:

[0065] 1) The installation structure of the parking air conditioner described in this embodiment has a first fixing part, a second fixing part and a third fixing part, which limit and fix the outdoor unit in both horizontal and vertical ways. At the same time, it increases the contact area between the mounting bracket and the outdoor unit, improves the connection stability of the mounting bracket, prevents the mounting bracket from deforming downward under the weight of the outdoor unit, and fully ensures the working stability of the outdoor unit.

[0066] 2) The installation structure of the parking air conditioner described in this embodiment has a shock-absorbing structure on the mounting bracket, which improves the shock absorption performance of the mounting bracket, reduces the wear and tear on the internal components of the parking air conditioner caused by bumps and swaying during vehicle operation, and reduces abnormal noise during the operation of internal components.

[0067] Example 2

[0068] Based on Example 1, in order to further improve the stability and vibration damping performance of the outdoor unit 2 installation, such as... Figure 7 As shown, a shock-absorbing clamping device 6 is provided on the mounting bracket 1. The shock-absorbing clamping device 6 effectively buffers the vibration caused by the shaking of the car to the outdoor unit 2, making the connection between the mounting bracket 1 and the outdoor unit 2 less prone to loosening.

[0069] More specifically, such as Figure 8 As shown, the shock-absorbing clamping device 6 includes an elastic element 61, a clamping block 62, and a shock-absorbing block 63. The elastic element 61 is connected to the mounting bracket 1. One end of the clamping block 62 is connected to the elastic element 61, and the other end of the clamping block 62 is connected to the shock-absorbing block 63. The shock-absorbing block 63 is in contact with the outdoor unit 2. The elastic element 61 effectively buffers the vibration caused by vehicle shaking to the outdoor unit 2. The clamping block 62 clamps and fixes the outdoor unit 2, preventing it from falling off and improving the stability of the outdoor unit 2 installation. The shock-absorbing block 63 reduces the surface friction of the parking air conditioner outdoor unit 2 caused by the bumps and swaying of the mounting bracket 1 during vehicle operation, thereby reducing the wear and tear on the surface of the outdoor unit 2 and reducing abnormal noise during the operation of internal parts.

[0070] More specifically, such as Figure 7 As shown, shock-absorbing clamping devices 6 are provided on both the first fixing part 12 and the third fixing part 15. The shock-absorbing clamping devices 6 on both the first fixing part 12 and the third fixing part 15 limit and fix the outdoor unit 2 and reduce vibration in the horizontal direction (front, back, left, and right), thereby improving the stability and vibration reduction performance of the outdoor unit 2 installation.

[0071] Example 3

[0072] Based on Example 2, in order to further improve the stability and vibration damping performance of the outdoor unit 2 installation, such as... Figure 9 , 10As shown in Figure 11, a mounting cover 4 is provided on the outside of the mounting frame 1, and the mounting cover 4 is connected to the cab 9. The mounting cover 4 can completely cover the mounting frame 1 and the outdoor unit 2, increasing the protection effect of the mounting frame 1 and the outdoor unit 2, preventing hard objects such as stones from directly impacting the mounting frame 1 and the outdoor unit 2, thus increasing safety. Moreover, the complete coverage can prevent the mounting frame 1 and the outdoor unit 2 from falling off the vehicle.

[0073] The housing 40 of the mounting cover 4 forms a mounting cavity inside, used to install the mounting bracket 1 and the outdoor unit 2. One or more spring clips (not shown in the figure) are arranged around the inner wall of the mounting cavity. Both ends of the spring clips are bent outwards and are installed on the inner wall of the mounting cavity. The elasticity of the spring clips effectively cushions the mounting bracket 1 and the outdoor unit 2, and also reduces noise.

[0074] One or more rubber blocks (not shown in the figure) are installed between the spring and the inner wall of the cover 40, which increases the buffering effect between the spring and the cover 40. When the spring bends, it will squeeze the rubber blocks, which can effectively increase the buffering effect and also play a role in noise reduction.

[0075] The connection method between the mounting cover 4 and the cab 9 is not limited. In this embodiment, preferably, the mounting cover 4 is installed to the cab 9 by expansion bolts.

[0076] More specifically, such as Figure 9 As shown, a first protruding edge 41, a second protruding edge 42, a third protruding edge 43, and a fourth protruding edge 44 are provided on the cover 40. A first connecting hole 411 is provided on the first protruding edge 41, a second connecting hole 421 is provided on the second protruding edge 42, a third connecting hole 431 is provided on the third protruding edge 43, and a fourth connecting hole 441 is provided on the fourth protruding edge 44. The arrangement of the first protruding edge 41, the second protruding edge 42, the third protruding edge 43, the fourth protruding edge 44, the first connecting hole 411, the second connecting hole 421, the third connecting hole 431, and the fourth connecting hole 441 facilitates the installation of the cover 4 on the cab 9.

[0077] More specifically, such as Figure 10 As shown, a second air outlet 401 is provided on the cover 40 of the mounting cover 4, and the second air outlet 401 cooperates with the first air outlet 22 of the outdoor unit 2. The provision of the second air outlet 401 facilitates the heat dissipation of the outdoor unit 2.

[0078] More specifically, the mounting cover 4 is connected to the outdoor unit 2.

[0079] In this embodiment, as Figure 11As shown, a shock-absorbing component 7 is also installed on the inner wall of the enclosure 40 for connecting the outdoor unit 2. The shock-absorbing component 7 provides shock absorption support for the outdoor unit 2. The shock-absorbing component 7 is a damping element that can achieve a shock absorption effect. The outdoor unit 2 can further achieve a shock absorption effect through the connection of the shock-absorbing component 7, and the shock-absorbing component 7 is set in multiple directions to achieve a multi-directional shock absorption effect.

[0080] The mounting cover 4 is connected to the outdoor unit 2 via the shock-absorbing component 7. This ensures that vibrations generated by the outdoor unit 2 are absorbed by the shock-absorbing component 7 before being transmitted to the mounting cover 4, achieving a better shock absorption effect.

[0081] In this embodiment, the shock absorption assembly 7 in the outdoor unit 2 includes a damping element that can achieve better shock absorption. One end of the damping element is connected to the outdoor unit 2, and the other end is connected to the mounting cover 4. The damping element includes a suspension spring 71, a shock absorber 72, and may also include an air damper, a liquid damper, etc. In this embodiment, the shock absorption assembly 7 is a suspension spring 71 and a shock absorber 72.

[0082] More specifically, in this embodiment, a suspension spring 71 is provided on the upper and front sides of the inner wall of the cover 40, and a shock absorber 72 is provided on the lower, left and right sides of the inner wall of the cover 40.

[0083] Example 4

[0084] Based on Example 3, in order to further improve the stability and vibration damping performance of the outdoor unit 2 installation, such as... Figure 11 As shown, the installation structure also includes a gas damping device 5. After being inflated, the gas damping device 5 not only serves to fix the outdoor unit 2, but also absorbs the vibration of the outdoor unit 2, thereby preventing the outdoor unit 2 from shaking and colliding with the mounting cover 4 and mounting bracket 1 as the transport vehicle moves. Moreover, the above structure is simple, and the gas damping device 5 can be deflated when the parking air conditioner is traveling on a flat road.

[0085] Specifically, such as Figure 11 As shown, the gas vibration damping device 5 includes a primary gas vibration damping device 51 and a secondary gas vibration damping device 52. The primary gas vibration damping device 51 is mounted on the mounting bracket 1 and is used to reduce the vibration between the outdoor unit 2 and the mounting bracket 1. The secondary gas vibration damping device 52 is mounted on the mounting cover 4 and is used to reduce the vibration between the mounting cover 4 and the outdoor unit 2 and the mounting bracket 1.

[0086] More specifically, such as Figure 11As shown, the primary gas shock absorber 51 includes a primary airbag assembly 510, which includes a first airbag 511 and a second airbag 512. The first airbag 511 is installed on the upper side of the second connecting plate 114, and the second airbag 512 is installed on the lower side of the second connecting plate 114.

[0087] More specifically, such as Figure 11 As shown, the secondary gas shock absorption device 52 includes a secondary airbag assembly 520, which includes a third airbag 521, a fourth airbag 522, a fifth airbag 523, a sixth airbag, and a seventh airbag. The third airbag 521 is installed above the inner wall of the cover 40; the fourth airbag 522 is installed below the inner wall of the cover 40; the fifth airbag 523 is installed in front of the inner wall of the cover 40; the sixth airbag is installed on the left side of the inner wall of the cover 40 (not shown in the figure); and the seventh airbag is installed on the right side of the inner wall of the cover 40 (not shown in the figure).

[0088] The primary gas damping device 51 and the secondary gas damping device 52 share a single electric air pump 502. The electric air pump 502 inflates the airbags of the primary airbag assembly 510 and the secondary airbag assembly 520. The electric air pump 502 is connected to the controller of the parking air conditioner. Each airbag is equipped with an air nozzle connected to a ventilation pipe. The electric air pump 502 has an air supply port. One end of the ventilation pipe is connected to the air nozzle, and the other end is connected to the air supply port.

[0089] More specifically, such as Figure 11 As shown, the mounting base for the electric air pump 502 is located on the side of the vehicle frame 8 near the cab 9, reducing the weight of the outdoor unit 2 mounting structure, lowering the mounting height of the electric air pump 502, and improving the installation stability of the electric air pump 502. A shock-absorbing housing (not shown in the figure) is provided on the outer wall of the electric air pump 502, reducing wear on the electric air pump 502 and effectively reducing vibration.

[0090] The ventilation pipe of the primary gas damping device 51 is mounted on the mounting frame 1, and the ventilation pipe of the secondary damping device is mounted inside the cover 40 of the mounting cover 4. The mounting frame 1 and the mounting cover 4 provide installation space for the ventilation pipe, protect the ventilation pipe, and support the gas damping device 5.

[0091] Example 5

[0092] Based on Example 4, this example proposes a control method for the installation structure of a parking air conditioner, wherein the control method for the installation structure of the parking air conditioner uses the above-mentioned installation structure of a parking air conditioner.

[0093] A road surface detection device is installed under the vehicle frame 8. The road surface monitoring device can collect road surface conditions and transmit the collected data to the parking air conditioner controller through a wireless communication module. The controller can determine the bumpiness when the vehicle body passes over it. If the road bumpiness level is level three, the controller issues an inflation command to both the primary gas damping device 51 and the secondary gas damping device 52. If the road bumpiness level is level two, the controller issues an inflation command to the primary gas damping device 51 and an deflation command to the secondary gas damping device 52. If the road bumpiness level is level one, the controller issues a deflation command to both the primary gas damping device 51 and the secondary gas damping device 52.

[0094] An alarm is installed on the control panel of the indoor unit inside the driver's cab 9. All alarms are electrically connected to the controller.

[0095] Each airbag is equipped with a pressure sensor to monitor the pressure inside the airbag, and the pressure sensor is electrically connected to the controller.

[0096] More specifically, the process of controlling the inflation of the gas damping device 5 is as follows:

[0097] S101, Received instruction to inflate gas damping device 5.

[0098] S102. Determine whether the vehicle body is in the process of transportation. If yes, execute S103; otherwise, execute S104.

[0099] S103, The controller controls the electric air pump 502 to inflate the gas damping device 5 so that the pressure inside the airbag reaches and is maintained within the first preset pressure range.

[0100] S104, the gas damping device 5 remains in its current state.

[0101] When the vehicle is parked, the parking air conditioner does not generate significant vibration, therefore the gas shock absorber 5 is not required. To save electricity and avoid inflating the airbags while the vehicle is parked, any inflation command received for the gas shock absorber 5 when the vehicle is not in transport (i.e., while parked) is an invalid command; however, any inflation command received for the airbags while the vehicle is in transport is a valid command.

[0102] More specifically, the process of controlling the venting of the gas damping device 5 is as follows:

[0103] S201, Received instruction to release gas from gas damping device 5;

[0104] S202. Determine whether the pressure inside the airbag of the gas damping device 5 is less than or equal to the second preset pressure. If yes, execute S203; otherwise, execute S204.

[0105] S203, the gas damping device 5 remains in its current state, and the alarm sounds.

[0106] S204. Depressurize the gas damping device 5 so that the pressure inside the airbag is less than or equal to the second preset pressure.

[0107] Before deflating the gas shock absorber 5, if the pressure inside the airbag of the gas shock absorber 5 is less than or equal to the second preset pressure, it indicates that the airbag has been deflated and there may be leakage in the airbag of the gas shock absorber 5. The alarm will sound to remind the driver to have it checked in time.

[0108] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
