Technical Field

[0001] The utility model relates to a compressor, in particular to a horizontal compressor, and more particularly to a low-vibration horizontal compressor and a vehicle-mounted air conditioner and a vehicle comprising the same. Background Art

[0002] The vehicle air conditioner and / or cooler is usually installed on the roof of the vehicle, which requires the height of the air conditioner and / or cooler to be as low as possible. Therefore, a horizontal compressor is usually selected for this type of vehicle air conditioner and / or cooler to ensure and meet the special requirements in terms of height.

[0003] Since the car air conditioner is installed on the roof, it is relatively close to the people in the vehicle, which makes it easy for consumers to feel the vibration and noise of the air conditioner. In reality, consumers have higher and higher requirements for vibration and noise, and the demand for quieter and more comfortable air conditioners (for example, reaching the same level as split air conditioners) has become more and more urgent.

[0004] Some prior arts use twin-cylinder compressors to reduce compressor vibration and the noise caused by the compressor, but they are still far from the expectations of consumers.

[0005] In other prior arts, a damping unit is further provided for the compressor to reduce vibration. The damping unit currently used generally provides vibration damping in the vertical direction for the compressor, thereby reducing the vibration of the compressor. However, in practice, such a damping unit still cannot significantly solve the vibration problem for a horizontal compressor.

[0006] Therefore, an improved compressor is urgently needed to improve the above-mentioned shortcomings. Utility Model Content

[0009] Specifically, in one aspect, the utility model provides a horizontal compressor, which includes a compressor body and a damping unit located on the lower side of the compressor body, wherein the damping unit includes at least one group of first damping devices, and the group of first damping devices are staggered on both sides of the compressor body, and their respective axes are respectively perpendicular to and intersect with the rotation axis of the compressor body.

[0010] According to a preferred aspect of the utility model, the group of first damping devices is a pair of damping devices symmetrically arranged on both sides of the compressor body, and two axes of the pair of damping devices intersect with the rotation axis of the compressor body and are perpendicular to the rotation axis of the compressor body.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0031] First, take the horizontal rotary compressor as an example, refer to Figure 1, which shows a compressor body of a horizontal rotary compressor, wherein the compressor body includes a crankshaft, a rotor, a stator, a balancing block, an eccentric part, a housing, etc. When the horizontal rotary compressor is working, these components will generate unbalanced rotational centrifugal force, and the magnitude and direction of the centrifugal force will change with the change of the rotation angle and speed.

[0032] refer to Figure 2 In order to reduce the vibration of the horizontal compressor, a damping structure in the vertical direction is usually provided for the horizontal compressor in the prior art. The damping structure provides buffering in the vertical direction and reduces the occurrence of noise to a certain extent.

[0033] In order to further solve the problem of vibration of a horizontal compressor and the noise caused thereby, the utility model provides an improved damping device having a damping unit with an inclined configuration. Specifically, as Figure 3-Figure 4 As shown, the compressor of the utility model includes a compressor body and a damping unit located at the lower side of the compressor body, wherein the damping unit includes two pairs of first damping devices symmetrically arranged on both sides of the compressor body and configured to be inclined, and two axes of the paired first damping devices intersect with the rotation axis of the compressor body and are perpendicular to the rotation axis of the compressor body.

[0034] Preferably, the horizontal compressor may be a horizontal rotary compressor or a horizontal scroll compressor.

[0035] Preferably, the first damping device comprises an elastic element. More preferably, the elastic element of the first damping device comprises a spring, rubber or a combination of a spring and rubber.

[0038] Preferably, the second damping device comprises an elastic element. Preferably, the elastic element of the second damping device comprises a spring, rubber or a combination of a spring and rubber.

[0039] Further references Figure 7 , which shows that the utility model Figure 3 The embodiment with tilt damping shown is different from the prior art such as Figure 2The excellent technical effect of the solution with vertical damping is shown.

[0040] like Figure 8 As shown, the inclined first damping device specially provided by the utility model fully resists the radial centrifugal force generated by the compressor during rotation, and the horizontal force components acting on the first damping device will be offset each other, significantly reducing the vibration caused in the horizontal direction.
