[0033] Reference below Figure 1-Figure 5 A vibration reduction assembly 20 for a compressor according to an embodiment of the present invention is described.

[0034] like Figure 1-Figure 5 As shown, the vibration reduction assembly 20 for a compressor according to an embodiment of the utility model includes: a support seat 21 and a vibration reduction rod 22 .

[0035] The vibration damping rod 22 is rotatably connected to the support base 21 around a rotation axis, and the two ends of the vibration damping rod 22 are respectively a first end 221 and a second end 222, and the first end 221 and the second end 222 are respectively located on both sides of the support base 21, wherein the first end 221 is suitable for being connected to the compressor 10, and the second end 222 is connected to an elastic member 24, and the elastic member 24 is suitable for being connected to the mounting bracket 101 of the vehicle 100.

[0036] Therefore, the compressor 10 is connected to the mounting bracket 101 of the vehicle 100 through the vibration damping assembly 20, so that the vibration damping assembly 20 can drive the elastic member 24 to elastically deform through the second end 222 of the vibration damping rod 22 to absorb the vibration transmitted from the first end 221, so as to reduce the vibration transmission between the compressor 10 and the mounting bracket 101 and improve the riding experience of the passengers in the vehicle.

[0037] For example, the support seat 21 is fixed on the mounting bracket 101, and after the vibration damping rod 22 is connected to the support seat 21, the vibration damping rod 22 can rotate around the rotation axis, so that the first end 221 and the second end 222 of the vibration damping rod 22 will make a circular motion, and the first end 221 and the second end 222 of the vibration damping rod 22 are respectively located on both sides of the support seat 21 so that the vibration damping rod 22 and the support seat 21 form a lever structure, and the first end 221 is connected to the compressor 10, and the second end 222 is connected to the elastic member 24, and the elastic member 24 is also connected to the mounting bracket 101, so that the compressor 10 and the mounting bracket 101 form a movable connection through the vibration damping assembly 20. Compared with a rigid connection, the vibration transmitted to the auxiliary instrument panel and the rear passengers can be reduced when the compressor 10 is running.

[0038] Furthermore, the vibration generated by the compression member during operation can drive the first end 221 to move, and the first end 221 drives the vibration damping rod 22 to rotate around the rotation axis, thereby stretching or compressing the elastic member 24 of the second end 222, that is, the elastic deformation of the elastic member 24 absorbs the vibration transmitted from the first end 221, thereby reducing the vibration transmission between the compressor 10 and the mounting bracket 101, and improving the riding experience of the passengers in the vehicle.

[0039] According to the vibration damping assembly 20 for the compressor in the embodiment of the utility model, the vibration damping rod 22 is arranged on the support seat 21 and can rotate around the rotation axis, and the first end 221 of the vibration damping rod 22 is connected to the compressor 10, and the second end 222 of the vibration damping rod 22 is provided with an elastic member 24, so that when the compressor 10 vibrates, the first end 221 will be driven to move, and the vibration will be transmitted from the first end 221 to the second end 222, so that the elastic member 24 can be elastically deformed to absorb the vibration, thereby reducing the vibration transmission between the compressor 10 and the mounting bracket 101, thereby improving the riding experience of the passengers in the vehicle.

[0040] In some embodiments, Figure 5As shown, the distance between the first end 221 and the rotation axis is smaller than the distance between the second end 222 and the rotation axis.

[0041] Therefore, according to the working principle of the lever: torque is equal to force multiplied by the lever arm, it can be known that the distance between the first end 221 and the rotation axis (the lever arm of the first end 221) is smaller than the distance between the second end 222 and the rotation axis (the lever arm of the second end 222). In this way, after the vibration force is transmitted from the first end 221 to the second end 222, since the lever arm of the first end 221 is smaller than the lever arm of the second end 222, the force received by the elastic member 24 of the second end 222 is smaller than the vibration force input by the first end 221. Therefore, the elastic member 24 can absorb the vibration of the first end 221 through a smaller elastic deformation, that is, the elastic member 24 can absorb the vibration between the compressor 10 and the mounting bracket 101 through a smaller elastic deformation, thereby playing a certain protective role for the elastic member 24 and helping to extend the service life of the elastic member 24.

[0042] For example, the distance between the first end 221 and the rotation axis is L1, and the distance between the second end 222 and the rotation axis is L2. In this embodiment, L1 and L2 can be L1=12mm, L2=22mm, the maximum vertical force generated by the vibration of the compressor 10 is F1, and the reaction force that the elastic member 24 can generate is F2. In this embodiment, F1 and F2 can be F1=350N, F2=218.2N. In this way, the theoretical torque generated by the compressor 10 is M1=F1*L1=42N*m, and the theoretical torque generated by the reaction force is M2=F2*L2=48N*m. In this way, M1<M2, thereby ensuring that the elastic member 24 can absorb the vibration that the compressor 10 can generate.

[0043] Furthermore, when the compressor 10 is connected to the vibration damping rod 22, the vibration damping rod 22 is pre-compressed M3=3N*m, so that the torque M4=M2-M3=45N*m generated by the reaction force, and M4 also satisfies M1<M4, so that the vibration generated by the compressor 10 can also be absorbed by the elastic member 24. At the same time, the pre-compression of the vibration damping rod 22 enables the entire system to be maintained in a balanced state after the compressor 10 is connected to the vibration damping rod 22, so that the compressor 10 can be maintained in a balanced state through the vibration damping rod 22 whether it is running or not.

[0044] In some embodiments, the elastic member 24 may be constructed as a spring, which makes it easier to connect the spring to the mounting bracket 101 and the second end 222. In other embodiments, the elastic member 24 may be constructed as a leaf spring or other forms.

[0045] In some embodiments, Figure 2-Figure 5 As shown, the support seat 21 is provided with a movable groove 211 , and the vibration reduction rod 22 is rotatably installed in the movable groove 211 .

[0046] Therefore, the vibration damping rod 22 can be installed in the movable groove 211 of the support seat 21, so that the vibration damping rod 22 can have sufficient movable space when rotating, and the vibration damping rod 22 located in the movable groove 211 can make the connection between the vibration damping rod 22 and the support seat 21 more stable, thereby ensuring that the connection between the compressor 10 and the mounting bracket 101 is more stable.

[0047] In some embodiments, Figure 5 As shown, the vibration reduction assembly 20 further includes: a first rotating shaft 25 , and the vibration reduction rod 22 is connected to the support seat 21 via the first rotating shaft 25 , and the rotation axis is the axis of the first rotating shaft 25 .

[0048] Therefore, the first rotating shaft 25 passes through the support seat 21 and the vibration damping rod 22, so that the vibration damping rod 22 is set on the support seat 21, so that the vibration damping rod 22 has higher stability after being set on the support seat 21, and at the same time, the rotation axis is the axis of the first rotating shaft 25, so that the vibration damping rod 22 rotates with the first rotating shaft 25 when rotating, so that the vibration damping rod 22 can rotate more smoothly.

[0049] In some embodiments, Figure 5 As shown, the first end 221 is rotatably connected to the second rotating shaft 26 , and the first end 221 is suitable for being connected to the compressor 10 through the second rotating shaft 26 .

[0050] Thus, the second rotating shaft 26 will pass through the first end 221, and the compressor 10 will be connected to the first end 221 through the second rotating shaft 26, so that the second rotating shaft 26 can enable the compressor 10 and the first end 221 to move relative to each other, avoiding a rigid connection between the two. At the same time, when the compressor 10 vibrates, it will drive the first end 221 to move up and down, thereby driving the vibration damping rod 22, and the first end 221 and the compressor 10 can also absorb part of the vibration when moving relative to each other, thereby playing a certain buffering role, and the first end 221 can also transmit the vibration energy to the second end 222 and enable the elastic member 24 at the second end 222 to further absorb the vibration.

[0051] In some embodiments, Figure 2-Figure 5 As shown, the second rotation axis 26 and the first rotation axis 25 are distributed along the extension direction of the vibration damping rod 22 .

[0052] Therefore, the distribution of the first rotating shaft 25 and the second rotating shaft 26 along the extension direction of the vibration damping rod 22 can meet the layout requirements of the compressor 10, and at the same time avoid interference between the movements of the first rotating shaft 25 and the second rotating shaft 26, so that the vibration damping rod 22 can transmit the vibration generated by the compressor 10 more easily.

[0053] In some embodiments, Figure 5As shown, the axis of the first rotation shaft 25 is parallel to the axis of the second rotation shaft 26 .

[0054] Therefore, the axes of the first rotating shaft 25 and the second rotating shaft 26 are parallel, so that when the vibration damping rod 22 rotates relative to the support base 21 and the first end 221 moves relative to the compressor 10, the axes of the two will be parallel, so that the two can be more stable during movement, and at the same time, the vibration will be more stable during the process of being transmitted from the first end 221 to the second end 222, so that the elastic member 24 can better absorb the vibration of the compressor 10 and thus improve the riding experience of the passengers in the vehicle.

[0055] The utility model also provides a vehicle-mounted refrigerator.

[0056] like Figure 1-Figure 3 As shown, the vehicle refrigerator according to the embodiment of the utility model comprises a compressor 10 and a vibration reduction assembly 20 for the compressor according to any one of the above embodiments.

[0057] According to the vehicle refrigerator of the present invention, the compressor 10 is installed on the mounting bracket 101 through the vibration reduction assembly 20. In this way, when the compressor 10 generates vibration during operation, the vibration reduction assembly 20 can absorb the vibration generated by the compressor 10, so that the vibration will not be transmitted from the vehicle refrigerator. In this way, the passengers in the car cannot feel the vibration, thereby improving the riding experience of the passengers.

[0058] In some embodiments, Figure 5 As shown, the first end 221 is connected to the bottom wall of the compressor 10 .

[0059] Therefore, when the first end 221 is connected to the compressor 10, it is connected to the bottom wall of the compressor 10, so that when the compressor 10 is running, the compressor 10 will vibrate and transmit the vibration to the second end 222 through the first end 221, so that the elastic member 24 of the second end 222 can absorb the vibration and prevent the vibration of the compressor 10 from being transmitted to the vehicle compartment.

[0060] Among them, when the first end 221 is connected to the bottom wall of the compressor 10, the vibration damping assembly 20 can absorb the vibration generated by the compressor 10 in the up and down directions. When the vibration damping assembly 20 needs to absorb vibrations in other directions, the first end 221 of the vibration damping assembly 20 can be connected to different parts of the compressor 10. For example, when the vibration damping assembly 20 needs to reduce the vibration generated by the compressor 10 in the left and right directions, the first end 221 will be connected to the side wall of the compressor 10.

[0061] For example, a connecting protrusion is provided on the side of the bottom wall of the compressor 10 facing the vibration damping rod 22, and the compressor 10 is connected to the first end 221 through the connecting protrusion, and the second rotating shaft 26 passes through the first end 221 and the connecting protrusion, so that the compressor 10 will drive the first end 221 to move along the height direction of the compressor 10 when vibrating. At the same time, the second rotating shaft 26 can make the first end 221 and the compressor 10 rotate relative to each other during movement, so that the first end 221 can drive the vibration damping rod 22 to rotate around the rotation axis, so that the vibration of the first end 221 can be transmitted to the second end 222, so that the elastic member 24 can absorb the transmitted vibration, thereby preventing the vibration of the compressor 10 during operation from affecting the occupants in the vehicle.

[0062] In some embodiments, a plurality of vibration damping assemblies 20 are provided. For example, in the present embodiment, four vibration damping assemblies 20 can be provided. The four vibration damping assemblies 20 are distributed at the bottom of the compressor 10 and around the geometric center of the bottom of the compressor 10. This can improve the installation stability of the compressor 10. At the same time, the plurality of vibration damping assemblies 20 can provide a better vibration damping effect, so that the vibration generated by the compressor 10 is not easily transmitted to the vehicle and thus affects the riding experience of the occupants.

[0063] The present invention also provides a vehicle 100 .

[0064] like Figure 6 As shown, a vehicle 100 according to an embodiment of the utility model includes a vehicle refrigerator according to any one of the above embodiments.

[0065] According to the vehicle 100 of the embodiment of the utility model, in the vehicle refrigerator, the vibration damping rod 22 is arranged on the support seat 21 and can rotate around the rotation axis, and the first end 221 of the vibration damping rod 22 is connected to the compressor 10, and the second end 222 of the vibration damping rod 22 is provided with an elastic member 24, so that when the compressor 10 vibrates, it will drive the first end 221 to move, and the vibration will be transmitted from the first end 221 to the second end 222, so that the elastic member 24 can be elastically deformed to absorb the vibration, thereby reducing the vibration transmission between the compressor 10 and the mounting bracket 101, thereby improving the riding experience of the occupants in the vehicle.
