[0054] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention. Those skilled in the art can make adjustments according to needs to adapt to specific application scenarios. For example, although this specific embodiment is described in the context of the damping device being applied to a vehicle, it is obvious that the damping device of the present invention can also be used in other scenarios. Such changes in the application scenario do not deviate from the basic principle of the present invention and fall within the protection scope of the present invention.

And, in addition to being able to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the embodiments of the present disclosure can be understood according to specific circumstances.
[0056] The compressor is the heart of the refrigeration system in an automotive air conditioning system and plays a role in compressing and transporting refrigerant vapor. For range-extended vehicles, rear-wheel drive vehicles, or vehicles where the compressor cannot be arranged on the motor due to insufficient layout space, the compressor is generally arranged on the vehicle's chassis bracket or the lower crossbeam of the body. Since the compressor generates vibrations during startup and operation, these vibrations are transmitted to the body through the chassis bracket, and then from the front panel to positions such as the steering wheel and footrest in the cockpit, seriously affecting the comfort inside the vehicle. Therefore, a vibration damping device needs to be set up to reduce the excitation vibration when the compressor is working. In the prior art, the compressor fixing bolts are sleeved with rubber pads, the gravity of the compressor acts on the lower rubber pad, and there is a rubber pad between the compressor and the bottom plate. However, the rubber pad has limited vibration absorption, and the vibration still transmits to the bottom plate.
[0057] First, as Figures 1-5 shown, the present invention provides a vibration damping device for a parking air conditioner. Among them, the parking air conditioner includes a compressor 1 and a bottom plate 2. The compressor 1 is arranged on the bottom plate 2 through the vibration damping device provided by the present invention. The vibration damping device includes a mounting bracket 3, a first elastic member 4, and a damping spring 5. The mounting bracket 3 is fixed above the bottom plate 2, and the compressor 1 is arranged on the mounting bracket 3. The first elastic member 4 is arranged between the mounting bracket 3 and the bottom plate 2. The damping spring 5 is sleeved on the first elastic member 4, and its two ends are respectively connected to the mounting bracket 3 and the bottom plate 2. Based on the above structural settings, the present invention secondarily absorbs the vibrations transmitted by the compressor 1 to the mounting bracket 3 through the first elastic member 4 and the damping spring 5. Among them, the damping spring 5 only supports a part of the process of the compressor 1 vibrating and absorbs most of the energy of the compressor 1 vibrating; the first elastic member 4 limits the maximum downward movement amplitude of the compressor 1, making the amplitude smaller. Therefore, the vibration damping device for a parking air conditioner provided by the present invention has a strong vibration absorption ability and a good vibration damping effect. It should be noted that the present invention does not impose any restrictions on the specific structures and the set numbers of the mounting bracket 3, the first elastic member 4, and the damping spring 5, and those skilled in the art can set them according to actual usage requirements.
[0058] In this preferred embodiment, the set size of the damping spring 5 affects the vibration absorption capacity of the damping device. Specifically, on the premise of the same amplitude, the larger the spring wire diameter d, the smaller the deformation degree of the damping spring 5, and the greater the bearing capacity that the damping spring 5 can provide. Conversely, the smaller the spring wire diameter d, the greater the deformation degree of the damping spring 5, and the better the vibration absorption capacity of the damping spring 5. Optionally, the spring wire diameter d can be 2 mm - 8 mm. On the premise of the same amplitude, the larger the spring inner diameter D, the greater the bearing capacity that the damping spring 5 can provide. At the same time, the vibration absorption capacity of the damping spring 5 is also better. It can be understood that the spring inner diameter D cannot exceed the width of the mounting bracket 3. Optionally, the spring inner diameter D can be 18 mm - 50 mm. On the premise of the same amplitude, the higher the spring free height L, the greater the bearing capacity that the damping spring 5 can provide. At the same time, the vibration absorption capacity of the damping spring 5 is also better. However, when the spring free height L is too high, the resilience is strong, which is likely to affect the stability of the compressor 1. Optionally, the spring free height L can be 20 mm - 50 mm.
[0059] In this preferred embodiment, the damping device provided by the present utility model further includes a fastener 6. The mounting bracket 3 is fixed to the bottom plate through the fastener 6 to prevent the mounting bracket 3 from slipping off the bottom plate 2 during the vibration of the compressor 1. Among them, the fastener 6 includes a stud 61 and a nut 62. A connection hole is provided on the mounting bracket 3. The stud 61 is welded to the bottom plate 2, and the stud 61 passes through the connection hole and is tightly connected to the nut 62, so that the mounting bracket 3 and the bottom plate 2 are tightly connected and have higher connection strength. It should be noted that the present utility model does not impose any restrictions on the specific structure and set size of the stud 61 and the nut 62, and those skilled in the art can set them according to actual usage requirements.
[0060] In this preferred embodiment, referring to Figure 1 , the number of the mounting brackets 3 can be two, which are used to support both ends of the compressor 1, so that the compressor 1 has better stability. At the same time, first elastic members 4, damping springs 5 and fasteners 6 are provided at both ends of each mounting bracket 3 to maintain the balance of the mounting bracket 3, and further make the damping device have strong vibration absorption capacity.
[0061] In this preferred embodiment, the first elastic member 4 is an annular gasket. The first elastic member 4 is sleeved on the stud 61 to ensure that the first elastic member 4 is always disposed between the mounting bracket 3 and the bottom plate 2, so as to prevent the first elastic member 4 from slipping off during the vibration of the compressor 1. In this preferred embodiment, the first elastic member 4 is provided with a convex portion 41. The convex portion 41 partially passes through the connection hole and extends towards the nut 62. The convex portion 41 and the top of the damping spring 5 form a connection groove for placing the end of the mounting bracket. It should be noted that the present utility model does not impose any restrictions on the specific structure and setting dimensions of the convex portion 41, and those skilled in the art can set them according to actual usage requirements.
[0062] In this preferred embodiment, the damping device provided by the present utility model further includes a second elastic member 7. The second elastic member 7 is disposed between the mounting bracket 3 and the nut 62. The second elastic member 7 isolates the direct contact between the mounting bracket 3 and the nut 62, so as to prevent abnormal noise caused by the rigid connection between the mounting bracket 3 and the nut 62 during the vibration of the compressor 1.
[0063] In this preferred embodiment, the second elastic member 7 is an annular gasket. The second elastic member 7 is sleeved on the stud 61. Similar to the first elastic member 4, the setting of the annular gasket can ensure that the second elastic member 7 is always disposed between the mounting bracket 3 and the nut 62, so as to prevent the second elastic member 7 from slipping off during the vibration of the compressor 1. In this preferred embodiment, the second elastic member 7 is provided with a clamping portion 71. The clamping portion 71 cooperates with the convex portion 41. The clamping portion 71 extends in a direction away from the nut 62 and is sleeved outside the convex portion 41. The cooperation between the clamping portion 71 and the convex portion 41 enables the first elastic member 4 and the second elastic member 7 to be clamped to each other. Furthermore, the vibration generated by the second elastic member 7 is directly transmitted to the first elastic member 4 without being transmitted through a rigid material, having a better damping effect.
[0064] In this preferred embodiment, the mounting bracket 3 is provided with a mounting groove 31. The compressor 1 is disposed on the mounting bracket 3 through the mounting groove 31, so as to prevent the compressor 1 from slipping off the mounting bracket 3 during the vibration of the compressor 1. It can be understood that the mounting groove 31 is adapted to the contour shape of the compressor 1, so that the compressor 1 is more stable when disposed in the mounting groove 31.
[0065] In addition, the present utility model further provides a vehicle, which includes a parking air conditioner and the vibration damping device for the parking air conditioner described in the above embodiments. Based on the above structural arrangement, the vehicle provided by the present utility model performs secondary absorption of the vibration transmitted from the compressor 1 to the mounting bracket 3 through the first elastic member 4 and the vibration damping spring 5. Among them, the vibration damping spring 5 only supports a part of the process of the compressor vibration and absorbs most of the energy of the compressor vibration; the first elastic member 4 limits the maximum downward movement amplitude of the compressor, making the amplitude smaller. Therefore, the vehicle provided by the present utility model has strong vibration absorption ability and good vibration damping effect.
[0066] It should be noted that the above embodiments are only used to illustrate the principle of the present utility model and are not intended to limit the protection scope of the present utility model. Without departing from the principle of the present utility model, those skilled in the art can adjust the above structure so that the present utility model can be applied to more specific application scenarios.
[0067] So far, the technical solution of the present utility model has been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present utility model is obviously not limited to these specific embodiments. Without departing from the principle of the present utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present utility model.
