[0049] like Figures 1-6 As shown, a bracket is used to install an air conditioning compressor 6 on a vehicle frame beam 5. The bracket includes a main board 1, a first side board 2, a first buffer assembly 3, and a second buffer assembly 4. Figures 1-2 The main board 1 is provided with a third mounting position 12 connected to the air conditioning compressor 6, and the main board 1 is formed with a first mounting position 11 connected to the first surface 51 of the frame beam 5. The first side plate 2 is connected to the main board 1 and has an angle with the main board 1, and the first side plate 2 is formed with a second mounting position 21 connected to the second surface 52 of the frame beam 5. The first mounting position 11 is connected to the first surface 51 through the first buffer component 3; and / or, the second mounting position 21 is connected to the second surface 52 through the second buffer component 4.

[0050] It should be noted that the frame beam 5 is located within the angle between the main board 1 and the first side board 2. The air conditioning compressor 6 is located on the side of the main board 1 away from the first surface 51. Preferably, the first side board 2 is perpendicular to the main board 1, and the angle between the two is 90°.

[0051] Preferably, the first mounting position 11 is connected to the first surface 51 through the first buffer assembly 3. At the same time, the second mounting position 21 is connected to the second surface 52 through the second buffer assembly 4.

[0052] Through the main board 1 and the first side plate 2 arranged at an angle, the bracket achieves full contact with at least two surfaces of the vehicle frame beam 5, ensuring a firm fixing effect of the bracket on the vehicle frame beam 5. Moreover, the stress points of the bracket on the vehicle frame beam 5 are more dispersed, avoiding stress concentration and ensuring structural stability. The air-conditioning compressor 6 is installed on the main board 1. Through the optimization of the bracket structure, the installation position of the air-conditioning compressor 6 on the vehicle frame beam 5 is further optimized, and the layout of the air-conditioning compressor 6 on the whole vehicle is optimized. Further, when the air-conditioning compressor 6 operates, the generated vibration will be transmitted to the vehicle body along the first mounting position 11 of the main board 1 - the first buffer assembly 3 - the first surface 51 of the vehicle frame beam 5, and along the second mounting position 21 of the first side plate 2 - the second buffer assembly 4 - the second surface 52 of the vehicle frame beam 5. The first buffer assembly 3 and the second buffer assembly 4 play a role in absorbing and reducing vibration in the above vibration transmission path, reducing the vibration and noise generated when the air-conditioning compressor 6 operates, and effectively improving the riding comfort.

[0053] Please refer to the attached Figure 3 , in some embodiments of the present application, the first buffer assembly 3 includes a first elastic member 31, a first connecting rod 32, and a second connecting rod 33; the first connecting rod 32 and the second connecting rod 33 are respectively connected to both ends of the first elastic member 31. Please refer to the attached Figures 5-6 , the first connecting rod 32 passes through and is fixed to the first mounting position 11, and the second connecting rod 33 passes through and is fixed to the first surface 51.

[0054] As above, through the cooperation of the first elastic member 31 with the first connecting rod 32 and the second connecting rod 33, a reliable connection of the first elastic member 31 between the first mounting position 11 and the first surface 51 is achieved. The first elastic member 31 can buffer the vibration transmitted from the first mounting position 11 to the first surface 51, and further reduce the vibration feeling transmitted from the air-conditioning compressor 6 to the vehicle body.

[0057] It should be noted that, in addition to the form of arranging the first connecting rod 32 and the second connecting rod 33 at both ends of the first elastic member 31 to connect the first elastic member 31 between the first installation position 11 and the first surface 51, the first buffer assembly 3 can also be arranged in other forms. For example, the first buffer assembly 3 includes the first elastic member 31, and both ends of the first elastic member 31 are respectively welded or bonded between the first installation position 11 and the first surface 51.

[0058] Furthermore, the first elastic member 31 can be selected from any one of elastic rubber, spring, bellows, airbag, hydraulic damper, etc.

[0059] Please refer to the appendix Figure 4 , in some embodiments, the second buffer assembly 4 includes a second elastic member 41, a third connecting rod 42, and a fourth connecting rod 43; the third connecting rod 42 and the fourth connecting rod 43 are respectively connected to both ends of the second elastic member 41.

[0062] As described above, the detachable installation of the second elastic member 41 between the second installation position 21 and the second surface 52 is realized, which facilitates the disassembly, repair, and replacement of the second buffer assembly 4.

[0063] It should be noted that, in addition to connecting the third link 42 and the fourth link 43 at both ends of the second elastic member 41 to connect the second elastic member 41 between the second mounting position 21 and the second surface 52, the second buffer assembly 4 may also be arranged in other forms.

In some embodiments of the present application, the first elastic member 31 is a first elastic rubber, and from both ends of the first elastic member 31 to the middle of the first elastic member 31, the radial dimension of the first elastic member 31 gradually decreases.

[0066] It should be noted that the axial direction of the first elastic member 31 is the direction from the first mounting position 11 to the first surface 51. Both ends of the first elastic member 31 are the two ends along the axial direction of the first elastic member 31. Preferably, the cross-section of the first elastic member 31 along the axial direction is circular.

[0067] As described above, a radially concave groove is formed on the outer periphery of the first elastic member 31, which is used for the force deformation of the first elastic member 31. While improving the buffering effect of the first elastic member 31, it avoids the first elastic member 31 from being damaged due to excessive force, improves the durability of the first elastic member 31, and further improves the vibration damping effect of the first buffer assembly 3.

[0068] Please refer to the atta Figure 4 chment. In some embodiments, the second elastic member 41 is a second elastic rubber, and from both ends of the second elastic member 41 to the middle of the second elastic member 41, the radial dimension of the second elastic member 41 gradually decreases.

[0069] It should be noted that the axial direction of the second elastic member 41 is the direction from the second mounting position 21 to the second surface 52.

Preferably, the cross-section of the second elastic member 41 along the axial direction is circular.

[0070] As described above, a radially concave groove is formed on the outer periphery of the second elastic member 41, which is used for the force deformation of the second elastic member 41. While improving the buffering effect of the second elastic member 41, it avoids the second elastic member 41 from being damaged due to excessive force, improves the durability of the second elastic member 41, and further improves the vibration damping effect of the second buffer assembly 4.

[0071] Please refer to the attached Figure 1 , in some embodiments of the present application, the first mounting position 11 is located at one end of the main board 1 away from the first side plate 2.

[0072] Furthermore, the second mounting position 21 is located at one end of the first side plate 2 away from the main board 1.

[0073] As above, the span between the first mounting position 11 and the second mounting position 21 is maximized, so that the bracket formed by the combination of the main board 1 and the first side plate 2 has a wider contact surface on the frame beam 5, which helps to improve the stability of the connection and fixation of the bracket on the frame beam 5.

[0074] Furthermore, a plurality of first mounting positions 11 are formed at intervals. Each first mounting position 11 is provided with a first mounting hole. As above, the number of mounting points for connecting the main board 1 to the first surface 51 is increased, ensuring a firm fixed connection of the main board 1 on the first surface 51.

[0075] Still further, a plurality of second mounting positions 21 are formed at intervals. Each second mounting position 21 is provided with a second mounting hole. As above, the number of mounting points for connecting the first side plate 2 to the second surface 52 is increased, ensuring a firm fixed connection of the first side plate 2 on the second surface 52.

[0076] Please refer to the attached Figure 2 , in some embodiments, the main board 1 and the first side plate 2 are integrally bent and formed.
