DETAILED DESCRIPTION

[0019] 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.

[0020] Embodiments of the present invention: Figure 1-Figure 4 As shown, an electric air compressor suspension bracket includes a bracket body 1, a suspension rubber pad mounting hole 2 is formed on the bracket body 1, the suspension rubber pad mounting hole 2 is a special-shaped hole, the suspension rubber pad mounting hole 2 includes an upper mounting surface 21, a lower mounting surface 22, a left mounting surface 23, a right mounting surface 24, a left inclined mounting surface 25 and a right inclined mounting surface 26, the upper mounting surface 21 and the lower mounting surface 22 are both horizontal planes, the left mounting surface 23 and the right mounting surface 24 are both vertical planes, the left inclined mounting surface 25 connects the left mounting surface 23 and the lower mounting surface 22, and the right inclined mounting surface 26 connects the right mounting surface 24 and the lower mounting surface 22.

[0021] The bracket body 1 is a left-right symmetrical structure, the left mounting surface 23 and the right mounting surface 24 are symmetrically arranged relative to the symmetry axis of the bracket body 1, the left inclined mounting surface 25 and the right inclined mounting surface 26 are symmetrically arranged relative to the symmetry axis of the bracket body 1, and the length of the upper mounting surface 21 is greater than the length of the lower mounting surface 22.

[0022] The bracket body 1 is a rectangular metal bracket, and the four outer sides of the bracket body 1 are all planes. The side of the bracket body 1 that contacts the frame is a plane, which ensures the contact area with the frame and improves the safety of the bracket body 1 after being fixed to the frame.

[0023] Specifically, the bracket body 1 is composed of a top plate 11 , a bottom plate 12 , a left side plate 13 and a right side plate 14 , and a countersunk hole 15 is respectively formed on the four corners of the bracket body 1 .

[0024] The bracket body 1 is fixed to the vehicle frame by four bolts. The countersunk holes 15 can be provided so that the bolt heads can be completely sunk into the holes, thereby preventing the bolt heads from wearing the passing pipelines, wiring harnesses and other flexible parts.

[0025] A group of first weight-reducing holes 16 are formed on the top plate 11 , a group of second weight-reducing holes 17 are formed on the bottom plate 12 , two third weight-reducing holes 18 are formed on the left side plate 13 , and two fourth weight-reducing holes 19 are formed on the right side plate 14 .

[0026] In this embodiment, the top plate 11 is preferably provided with five first weight-reducing holes 16, and the five first weight-reducing holes 16 are arranged in a row at equal intervals. Five second weight-reducing holes 17 are also preferably provided. The two third weight-reducing holes 18 on the left side plate 13 are respectively arranged at positions close to the two countersunk holes 15 on the left side. The two fourth weight-reducing holes 19 on the right side plate 14 are respectively arranged at positions close to the two countersunk holes 15 on the right side.

[0027] It should be noted that the number of the first weight-reducing hole 16, the second weight-reducing hole 17, the third weight-reducing hole 18 and the fourth weight-reducing hole 19 can be increased or decreased according to actual needs. In this embodiment, they are all waist-shaped holes, and their sizes are the same. The arrangement of the first weight-reducing hole 16, the second weight-reducing hole 17, the third weight-reducing hole 18 and the fourth weight-reducing hole 19 can not only reduce the weight of the bracket body 1, but also ensure that there will be no defects such as shrinkage during the casting process.

[0028] Furthermore, the thickness of the bottom plate 12 , the left side plate 13 and the right side plate 14 is greater than the thickness of the top plate 11 , and the connection position between the upper ends of the left side plate 13 and the right side plate 14 and the top plate 11 forms a step 3 .

[0029] The thickness of the bottom plate 12, the left side plate 13 and the right side plate 14 is designed to be greater than the thickness of the top plate 11, so that the load-bearing capacity of the bracket body 1 can be improved. The structure of the step 3 can facilitate the installation and replacement of the suspension pad 4, and also facilitate the lifting of the electric air compressor from above.

[0030] Furthermore, both ends of the left inclined mounting surface 25 are in arc transition with the left mounting surface 23 and the lower mounting surface 22, and both ends of the right inclined mounting surface 26 are in arc transition with the right mounting surface 24 and the lower mounting surface 22; the lower mounting surface 22 is higher than the lowest point of the left inclined mounting surface 25 and the right inclined mounting surface 26.

[0031] The left inclined mounting surface 25 and the arc surfaces at both ends are used to cooperate with the end of the left inclined support part of the suspension rubber pad 4, and the right inclined mounting surface 26 and the arc surfaces at both ends are used to cooperate with the end of the right inclined support part of the suspension rubber pad 4, so that the left inclined support part and the right inclined support part of the suspension rubber pad 4 will not slide on the left inclined mounting surface 25 and the right inclined mounting surface 26 when the suspension rubber pad 4 is under force, thereby playing an effective supporting role.

[0032] Preferably, the lower mounting surface 22, the left inclined mounting surface 25 and the right inclined mounting surface 26 are all inclined inwardly by 2.3°. It should be noted that the inclination angle can be adjusted according to demand, and the inward inclination of 2.3° adopted in this embodiment is only a preferred solution.

[0033] The side of the bracket body 1 connected to the vehicle frame is the inner side, and the side of the bracket body 1 facing the suspension rubber pad 4 is the outer side. By tilting the lower mounting surface 22, the left inclined mounting surface 25 and the right inclined mounting surface 26 inward by 2.3°, the suspension rubber pad 4 and the bracket body 1 are self-locked after being assembled, and the movement range of the suspension rubber pad 4 during the compression process is limited, which can completely prevent it from coming off the bracket body 1. At the same time, the suspension rubber pad 4 is limited to ensure that it will not be compressed outside the preset range under extreme working conditions, which greatly improves the service life and safety of the suspension rubber pad 4.

[0034] When in use, one suspension rubber pad 4 needs to be installed with two bracket bodies 1. After the two ends of the suspension rubber pad 4 are respectively plugged into the suspension rubber pad mounting holes 2 on the two bracket bodies 1, the two bracket bodies 1 are fixed to the vehicle frame with bolts, and finally the electric air compressor is installed on the suspension rubber pad 4.

[0035] 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.
