DETAILED DESCRIPTION

[0018] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0019] Embodiments of the present invention: Figure 1-Figure 3 As shown, an electric air compressor suspension device includes a suspension rubber pad assembly 1 and a suspension bracket 2. The number of the suspension brackets 2 is two. The suspension brackets 2 are provided with suspension rubber pad assembly mounting holes 3. The suspension rubber pad assembly 1 is plug-connected with the suspension rubber pad assembly mounting holes 3 on the two suspension brackets 2. The suspension rubber pad assembly 1 includes a rubber block and a metal support frame. The rubber block is vulcanized on the metal support frame.

[0020] The two ends of the suspension rubber pad assembly 1 are plugged into the rubber pad assembly mounting holes 3 on the two suspension brackets 2, and the two suspension brackets 2 are fixed to the vehicle frame. The suspension rubber pad assembly 1 is fixed in this way, and bolts do not need to be provided on the suspension rubber pad assembly 1, which solves the problem of bolt breakage and falling off in the prior art. The reliability and safety of the installation of the electric air compressor are improved.

[0021] Specifically, the metal support frame includes an upper support plate 4, a lower support plate 5, a left support plate 6, a right support plate 7, a first middle support plate 8 and a second middle support plate 9. The upper support plate 4 and the lower support plate 5 are arranged horizontally. The length of the upper support plate 4 is greater than the length of the lower support plate 5. The upper ends of the first middle support plate 8 and the second middle support plate 9 are fixedly connected to the upper support plate 4, and the lower ends of the first middle support plate 8 and the second middle support plate 9 are fixedly connected to the lower support plate 5. A guide pin 12 is fixedly provided at the center position of the top surface of the upper support plate 4, and the top end of the guide pin 12 has a conical end head 21.

[0022] By providing the metal support frame, the suspension rubber pad assembly 1 has better shock absorption performance, longer service life and is not prone to breakage.

[0023] The guide pin 12 is used to connect with the electric air compressor and plays a positioning role, and the conical end 21 plays a guiding role to facilitate the assembly of the electric air compressor.

[0024] Both the rubber block and the metal support frame are axisymmetric structures. The first middle support plate 8 and the second middle support plate 9 are arranged symmetrically relative to the symmetry axis of the metal support frame. The upper and lower ends of the first middle support plate 8 and the second middle support plate 9 extend in the vertical direction, and the middle parts of the first middle support plate 8 and the second middle support plate 9 extend obliquely.

[0025] In this embodiment, the upper end spacing between the first middle support plate 8 and the second middle support plate 9 is greater than the lower end spacing between the two, the middle portion of the first middle support plate 8 is inclined toward the direction close to the second middle support plate 9, and the middle portion of the second middle support plate 9 is inclined toward the direction close to the first support plate 8. With this structural design, the first middle support plate 8 and the second middle support plate 9 not only have better supporting performance, but also are easy to deform, thereby improving the vibration isolation effect of the suspension rubber pad assembly 1.

[0026] Furthermore, the left support plate 6 and the right support plate 7 are symmetrically arranged relative to the symmetry axis of the metal support frame, the upper parts of the left support plate 6 and the right support plate 7 are perpendicular to the upper support plate 4, and the lower parts of the left support plate 6 and the right support plate 7 extend obliquely away from each other.

[0027] The upper part of the left support plate 6 is welded and fixed to the upper part of the middle first support plate 8, and the lower part of the left support plate 6 extends to the lower left, the upper part of the right support plate 7 is welded and fixed to the upper part of the middle second support plate 9, and the lower part of the right support plate 7 extends to the lower right. That is, the lower part of the left support plate 6 and the lower part of the right support plate 7 are in an eight-shaped shape.

[0028] In this embodiment, the upper support plate 4, the lower support plate 5, the left support plate 6, the right support plate 7, the first middle support plate 8 and the second middle support plate 9 are all elastic metal plates. The selection of specific metal materials and the selection of elasticity can be selected according to actual needs and do not belong to the protection scope of this application.

[0029] A left end plate 10 is fixedly disposed at the lower end of the left support plate 6, and a right end plate 11 is fixedly disposed at the lower end of the right support plate 7. The left end plate 10 is arranged vertically with the left support plate 6, and the right end plate 11 is arranged vertically with the right support plate 7.

[0030] Furthermore, the rubber block includes a rubber block body 13, a left support block 14, a right support block 15 and a bottom support block 16. The left support block 14 and the right support block 15 are located on both sides of the rubber block body 13. The left support block 14 and the right support block 15 are both arranged at an angle, and the bottom support block 16 is vulcanized at the bottom of the lower support plate 5.

[0031] The first middle support plate 8 and the second middle support plate 9 are completely wrapped by the rubber block body 13, the left support plate 6 is completely wrapped by the left support block 14, and the right support plate 7 is completely wrapped by the right support block 15. The top surface of the rubber block body 13 is fixed by vulcanization to the bottom surface of the upper support plate 4, and the bottom surface of the rubber block body 13 is fixed by vulcanization to the top surface of the lower support plate 5. The upper support plate 4 plays a role in supporting the electric air compressor.

[0032] Preferably, a protrusion 22 is formed on the side wall of the lower end of the left support block 14 and the right support block 15, the left end plate 10 is fixed to the end of the left support block 14 by vulcanization, and the two ends of the left end plate 10 are bent back to cover the protrusion 22 on the left support block 14. The two ends of the right end plate 11 are bent back to cover the protrusion 22 on the right support block 15.

[0033] Furthermore, the suspension bracket 2 is a rectangular frame, the top and bottom surfaces of the suspension rubber pad assembly mounting hole 3 are both horizontal planes, the left side of the suspension rubber pad assembly mounting hole 3 has a left mounting groove 17, the right side of the suspension rubber pad assembly mounting hole 3 has a right mounting groove 18, and both ends of the left mounting groove 17 and the right mounting groove 18 are arc-shaped. The left mounting groove 17 and the right mounting groove 18 are arranged in an inverted "eight" shape. A plurality of weight-reducing holes 19 are provided around the suspension bracket 2, and a step hole 20 is provided at each of the four corners of the suspension bracket 2.

[0034] After the suspension rubber pad assembly 1 is inserted into the suspension rubber pad assembly mounting hole 3 on the suspension bracket 2, the top surface of the upper support plate 4 contacts the top surface of the suspension rubber pad assembly mounting hole 3, the left end plate 10 is located in the left mounting groove 17, and the right end plate 11 is located in the right mounting groove 18. Through the cooperation of this structure, the suspension rubber pad assembly 1 and the suspension bracket 2 are self-locking after being assembled, without the need to use bolts to fix.

[0035] Under normal circumstances, there is a certain gap between the bottom support block 16 and the bottom surface of the mounting hole 3 of the suspension rubber pad assembly, and the two do not contact. However, when one or more of the left support plate 6, the right support plate 7, the left support block 14, and the right support block 15 fail, the bottom support block 16 contacts the bottom surface of the mounting hole 3 of the suspension rubber pad assembly, bearing the weight of the electric air compressor, which is a redundant design structure of the suspension rubber pad assembly 1.

[0036] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
