[0026] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solutions of the present invention, and to facilitate its implementation.

[0027] It should be noted that in the following embodiments, the terms "first", "second", "third" and "fourth" do not represent an absolute distinction in structure and / or function, nor do they represent the order of execution, but are merely for the convenience of description.

[0028] Example 1

[0029] like Figures 1 to 6 As shown, this embodiment of the invention provides an air conditioner compressor installation device, including a first bracket 1, a second bracket 2, and a third bracket 3. The first bracket 1 and the second bracket 2 are disposed on the third bracket 3, and shock-absorbing pads 4 are disposed between the first bracket 1 and the second bracket 2 and the third bracket 3. A receiving cavity for accommodating the air conditioner compressor is formed between the first bracket 1 and the second bracket 2. The air conditioner compressor is connected to the first bracket 1 and the second bracket 2 through a first fixing mechanism. Multiple shock-absorbing pads 4 are disposed between the first bracket 1 and the third bracket 3. Multiple shock-absorbing pads 4 are disposed between the second bracket 2 and the third bracket 3.

[0030] Specifically, the shock-absorbing pad 4 is made of rubber, which has good elasticity and shock absorption performance. The first bracket 1, the second bracket 2, and the third bracket 3 are made of metal. The third bracket 3 is used for mounting on the vehicle body. The first bracket 1 and the second bracket 2 are connected to the third bracket 3 through a second fixing mechanism. The first bracket 1 and the second bracket 2 adopt a symmetrical design and are interchangeable. The first bracket 1 and the second bracket 2 have the same structure. Due to the symmetry of the design, the first bracket 1 and the second bracket 2 can interchange positions or functions, increasing the flexibility and convenience of installation. The fact that the first bracket 1 and the second bracket 2 have the same structure further emphasizes their interchangeability and versatility.

[0031] like Figures 1 to 6As shown, in this embodiment of the invention, the first fixing mechanism includes a first bolt 5, a main nut 6, and a secondary nut 7. A first through hole is provided on the first bracket 1 and the second bracket 2 for the first bolt 5 to pass through. The main nut 6 and the secondary nut 7 are threadedly connected to the first bolt 5, and the secondary nut 7 is located between the main nut 6 and the second bracket 2. The main nut 6 is a common nut, and the secondary nut 7 is fixedly connected to the main nut 6. The secondary nut 7 is made of an elastic material, and both the secondary nut 7 and the main nut 6 are made of metal. The secondary nut 7 can undergo elastic deformation, and the central hole of the secondary nut 7 and the main nut 6 is a threaded hole.

[0032] like Figures 3 to 6 As shown, the first fixing mechanism also includes an anti-loosening element 8 disposed between the external threads of the secondary nut 7 and the first bolt 5. The secondary nut 7 is provided with a positioning groove to accommodate the anti-loosening element 8, and the anti-loosening element 8 is clamped between the main nut 6 and the secondary nut 7. The anti-loosening element 8 is a rubber ring with a circular structure. The anti-loosening element 8 is sleeved on the first bolt 5, and the anti-loosening element 8 is coaxially arranged with the first bolt 5, the secondary nut 7, and the main nut 6.

[0033] During the tightening of the main nut 6, the secondary nut 7 deforms, generating an elastic force on the first bolt 5 in both axial and radial inward directions (towards the axis). The secondary nut 7 fits tightly against the first bolt 5, with its internal thread engaging closely with the external thread of the first bolt 5, achieving an anti-loosening effect and axially limiting the main nut 6, making it less prone to loosening and improving the reliability of the air conditioning compressor installation. Furthermore, during the tightening of the main nut 6, the anti-loosening element 8 deforms under the pressure of the main nut 6 and the secondary nut 7. The anti-loosening element 8 deforms radially along the first bolt 5, embedding itself in the groove between two adjacent threads on the first bolt 5. The anti-loosening element 8 presses against the first bolt 5, increasing additional friction. The cooperation between the anti-loosening element 8 and the secondary nut 7 further enhances the anti-loosening effect.

[0034] like Figures 4 to 6 As shown, a first deformation groove 9 and a second deformation groove 10 are respectively provided on the first surface 11 and the second surface 12 of the auxiliary nut 7. The distance between the first deformation groove 9 and the axis of the auxiliary nut 7 is greater than the distance between the second deformation groove 10 and the axis of the auxiliary nut 7. The first surface 11 and the second surface 12 are opposite side surfaces of the auxiliary nut 7. The first surface 11 is in contact with one end face of the main nut 6 in the axial direction. The first surface 11 and the second surface 12 are planes perpendicular to the axis of the auxiliary nut 7. The first deformation groove 9 is a groove extending along the entire circumference on the first surface 11, and the second deformation groove 10 is a groove extending along the entire circumference on the second surface 12. The first deformation groove 9 and the second deformation groove 10 are arc-shaped grooves. The provision of the first deformation groove 9 and the second deformation groove 10 increases the deformation space of the auxiliary nut 7 when subjected to pressure.

[0035] In this embodiment of the invention, the secondary nut 7 is further provided with weakening grooves. Multiple weakening grooves are provided, and all weakening grooves are evenly distributed circumferentially with the axis of the secondary nut 7 as the center line. The weakening grooves extend radially along the secondary nut 7, starting from the first deformation groove 9 and extending to the center of the secondary nut 7. The weakening grooves also penetrate axially along the secondary nut 7, dividing the secondary nut 7 into multiple segments. Simultaneously, the first deformation groove 9 and the second deformation groove 10 are staggered, facilitating deformation of the secondary nut 7. The weakening grooves not only further increase the deformation space but also reduce the overall rigidity by dividing the secondary nut 7 into multiple segments. This design makes it easier for the secondary nut 7 to undergo the expected deformation under stress and ensures that the nut will not be damaged during deformation. The staggered arrangement of the first deformation groove 9 and the second deformation groove 10 avoids mutual interference between the two during deformation, ensuring the uniformity and controllability of the deformation.

[0036] like Figures 4 to 6 As shown, the secondary nut 7 has a third surface 13 and a fourth surface 14, which are opposite sides of the secondary nut 7. The third surface 13 is located between the first surface 11 and the anti-loosening element 8, and the anti-loosening element 8 is located between the third surface 13 and the axis of the secondary nut 7. The fourth surface 14 is located between the second surface 12 and the axis of the secondary nut 7. The third surface 13 and the fourth surface 14 are planes perpendicular to the axis of the secondary nut 7. The first surface 11 and the third surface 13 are located at one end of the secondary nut 7, and the second surface 12 and the fourth surface 14 are located at the other end of the secondary nut 7. In the initial state, as shown... Figure 5 As shown, the main nut 6 is not tightened, there is a gap between the third surface 13 and the end face of the main nut 6, and the distance between the second surface 12 and the main nut 6 is less than the distance between the fourth surface 14 and the main nut 6. That is, the first surface 11 and the third surface 13 are not in the same plane perpendicular to the axis of the auxiliary nut 7, and the second surface 12 and the fourth surface 14 are also not in the same plane perpendicular to the axis of the auxiliary nut 7. The fourth surface 14 will contact the surface of the second bracket 2 before the second surface 12.

[0037] like Figure 6 As shown, after the main nut 6 is tightened, the secondary nut 7 deforms. The first nut and the third nut are in contact with the same end face of the main nut 6. The first surface 11 and the third surface 13 are in the same plane perpendicular to the axis of the secondary nut 7. The second surface 12 and the fourth surface 14 are also in the same plane perpendicular to the axis of the secondary nut 7. The second surface 12 and the fourth surface 14 are in contact with the same surface of the second bracket 2.

[0038] The secondary nut 7 in the above structure has its two end surfaces arranged in a staggered manner. In this way, during the tightening process of the main nut 6, the greater the axial pressure applied by the main nut 6 to the secondary nut 7, the greater the deformation of the secondary nut 7. The metal at the third surface 13 and the fourth surface 14 is more likely to deform, making it easier to reduce the gap of the weakening groove. The threads of the secondary nut 7 are more likely to engage with the threads of the first bolt 5, further improving the anti-loosening effect.

[0039] like Figure 1 As shown, in this embodiment of the invention, two shock-absorbing pads 4 are provided between the first support 1 and the third support 3, and two shock-absorbing pads 4 are provided between the second support 2 and the third support 3. The second fixing mechanism mainly includes a second bolt and a nut. The first support 1, the second support 2, and the shock-absorbing pads 4 are provided with second through holes through which the second bolt passes. The axis of the second through hole is perpendicular to the axis of the first through hole in space. The first support 1 is connected to the third support 3 through two second fixing mechanisms, and the second support 2 is connected to the third support 3 through two second fixing mechanisms. Correspondingly, the first support 1 and the second support 2 are each provided with two second through holes, and the third support 3 is provided with four through holes through which the second bolt passes. The axes of the four through holes are parallel, and the four through holes are distributed in a rectangular shape.

[0040] In this embodiment of the invention, two first fixing mechanisms are provided. Correspondingly, two first through holes are provided on the first bracket 1 and the second bracket 2. The axes of the two first through holes are parallel. The air conditioner compressor is provided with through holes through which two first bolts 5 pass.

[0041] Example 2

[0042] like Figure 7 As shown in the embodiment of the invention, the structures of the first bracket 1 and the second bracket 2 are not exactly the same. The first bracket 1 is also provided with a reinforcing plate 15. The first bracket 1 mainly includes a first mounting plate 16 and a second mounting plate 17 fixedly connected. The first mounting plate 16 and the second mounting plate 17 are perpendicular to each other. The first mounting plate 16 is parallel to the third bracket 3. The second mounting plate 17 is located between the first mounting plate 16 and the third bracket 3. The air conditioning compressor is installed between the second mounting plate 17 and the second bracket 2. The first mounting plate 16 is provided with a second through hole for the second bolt to pass through. The second mounting plate 17 is provided with a first through hole for the first bolt 5 to pass through. The shock-absorbing pad 4 is located between the first mounting plate 16 and the third bracket 3. The reinforcing plate 15 is fixedly connected to the first mounting plate 16 and the second mounting plate 17. Multiple reinforcing plates 15 are provided. All reinforcing plates 15 are arranged sequentially along the length direction of the first mounting plate 16 and the second mounting plate 17. The length direction of the first mounting plate 16 and the second mounting plate 17 is perpendicular to the axis of the first through hole and the second through hole.

[0043] The first bolt 5 includes a hexagonal head 18 and a threaded section for fixed connection. The threaded section has external threads. A main nut 6 and a secondary nut 7 are located on the threaded section. The hexagonal head 18 has a regular hexagonal structure and is inserted between two adjacent reinforcing plates 15. Two parallel outer surfaces of the hexagonal head 18 (the centerline of the hexagonal head 18 is located between these two parallel outer surfaces, which is also the axis of the first bolt 5) are respectively in contact with the two reinforcing plates 15. During the tightening of the main nut 6, the hexagonal head 18 is inserted between the two reinforcing plates 15, preventing the first bolt 5 from rotating. The first bolt 5 remains stationary, facilitating assembly, simplifying the assembly process, and improving assembly efficiency. Simultaneously, the reinforcing plates 15 enhance the overall structural strength of the first bracket 1 and increase its load-bearing capacity. Furthermore, after the main nut 6 is tightened, the hexagonal head 18 remains inserted between the two reinforcing plates 15, providing a certain degree of anti-loosening effect and reducing the risk of bolt loosening due to vibration and other reasons, further improving the reliability of the installation device.
