A first aspect of the present application provides a mounting assembly 10 for a vacuum pump, fig. 1 is a schematic structural diagram of the mounting assembly 10 for a vacuum pump and the vacuum pump 20 provided in the present application in a connection state, fig. 2 is a schematic structural diagram of the structure shown in fig. 1 in another view, and fig. 3 is a schematic structural explosion diagram of the structure shown in fig. 2.

Referring to fig. 1-3, a vacuum pump mounting assembly 10 includes a mounting bracket 11, a first shock absorbing structure 12, and a second shock absorbing structure 13, the mounting bracket 11 being configured to mount a vacuum pump 20, the first shock absorbing structure 12 and the second shock absorbing structure 13 being configured to absorb shock from the vacuum pump 20.

Specifically, the mounting bracket 11 is provided with a mounting plate 111 and mounting arms 112, the mounting arms 112 being provided in a convex manner with respect to the top surface of the mounting plate 111 and being located on opposite sides of the mounting plate 111. At this time, the mounting arms 112 are provided in two, and the two mounting arms 112 are respectively located at opposite sides of the mounting plate 111, and the main structure of the mounting arms 112 may be disposed substantially perpendicular to the mounting plate 111. To ensure structural stability, two mounting arms 112 may be integrally formed with mounting plate 111.

The first shock-absorbing structure 12 is provided on the mounting plate 111, the first shock-absorbing structure 12 is supported on the mounting plate 111 by its elastic portion, and a portion of the first shock-absorbing structure 12 is located at the bottom of the mounting plate 111 to be connected with the vacuum pump 20, and the vacuum pump 20 is carried on the mounting plate 111 by the first shock-absorbing structure 12. It will be appreciated that the first shock absorbing structure 12 is provided with an elastic portion which is capable of elastic deformation upon compression.

The first shock absorbing structure 12 may be partially located at the top of the mounting plate 111 and partially located at the bottom of the mounting plate 111, and at this time, the first shock absorbing structure 12 may be supported on the mounting plate 111 by an elastic portion located at the top of the mounting plate 111, and the portion of the first shock absorbing structure 12 located at the bottom of the mounting plate 111 may be connected to the vacuum pump 20. Based on this arrangement, the vacuum pump 20 is suspended from the mounting plate 111 by the first shock-absorbing structure 12, and at this time, the connection between the vacuum pump 20 and the mounting plate 111 is achieved only by the first shock-absorbing structure 12.

The second shock absorbing structure 13 is provided on the mounting arm 112, the second shock absorbing structure 13 is fixed with the vehicle body fixing structure 21, and the second shock absorbing structure 13 supports the mounting arm 112 by its elastic portion so that the mounting bracket 11 is carried on the second shock absorbing structure 13. The vehicle body fixing structure 21 may be a structure such as a vehicle body or a fixing bracket provided on a vehicle body, and is not particularly limited. The structure of the second shock absorbing structure 13 includes an elastic portion that can be elastically deformed. It should be understood that the mounting bracket 11 is only connected to the body securing structure 21 by the second shock absorbing structure 13, in which case the mounting bracket 11 is suspended from the second shock absorbing structure 13.

In combination with the above, the vacuum pump 20 is suspended from the mounting bracket 11 by the first shock absorbing structure 12, and the mounting bracket 11 is suspended from the vehicle body fixing structure 21 by the second shock absorbing structure 13. When the vacuum pump 20 vibrates, the vacuum pump 20 elastically deforms the elastic portion of the first shock-absorbing structure 12 to reduce the transmission of the vibration of the vacuum pump 20 to the mounting bracket 11 through the first shock-absorbing structure 12. Part of the vibration of the vacuum pump 20 is transmitted to the mounting bracket 11, and the mounting bracket 11 vibrates to elastically deform the elastic portion of the second shock absorbing structure 13 to reduce the transmission of the vibration of the mounting bracket 11 to the vehicle body fixing structure 21 through the second shock absorbing structure 13. Therefore, by the above arrangement, shock transmission of the vacuum pump 20 is reduced by the first shock absorbing structure 12 and the second shock absorbing structure 13.

Fig. 4 is a sectional view of the structure shown in fig. 2 along a section line A-A, fig. 5 is a schematic structural view of the first elastic member 121 shown in fig. 3, fig. 6 is a schematic structural view of the first elastic member 121 shown in fig. 5 at another viewing angle, and fig. 7 is a sectional view of the first elastic member 121 shown in fig. 5 along a section line B-B.

Referring to fig. 4-7, in some embodiments, the first shock absorbing structure 12 includes a first elastic member 121 and a first fixing member 122, and the first fixing member 122 passes through the first elastic member 121 and the mounting plate 111. At least part of the first elastic member 121 is pressed against the top wall of the mounting plate 111 by the first fixing member 122, and the bottom of the first fixing member 122 is used for connecting with the vacuum pump 20.

Specifically, the first elastic member 121 may be provided with a through hole along a height direction thereof, and the mounting plate 111 may be provided with a through hole, so that the first fixing member 122 may pass through the first elastic member 121 and the through hole on the mounting plate 111, and further the first fixing member 122 may pass through the first elastic member 121 and the mounting plate 111. At this time, the first fixing member 122 may directly pass through the through hole of the first elastic member 121, and the first elastic member 121 passes through the through hole of the mounting plate 111, so that the first fixing member 122 indirectly passes through the through hole of the mounting plate 111. The first elastic member 121 may be partially or entirely pressed against the top wall of the mounting plate 111, and the portion of the first elastic member 121 is shown in the drawings to be pressed against the top wall of the mounting plate 111, but is not limited thereto. The bottom of the first fixing member 122 passes through the mounting plate 111 to be positioned below the mounting plate 111 so that the bottom of the first fixing member 122 is fixedly connected with the vacuum pump 20.

In order to facilitate the pressing of the first fixing member 122 against the first elastic member 121, a head portion may be disposed at the top of the first fixing member 122, and the head portion of the first fixing member 122 may have an outer diameter larger than that of other portions thereof. At this time, the inner diameter of the through hole on the first elastic member 121 may be approximately equal to the outer diameter of the other portion of the first fixing member 122, and when the first fixing member 122 passes through the through hole on the first elastic member 121, the head of the first fixing member 122 may press against the top of the first elastic member 121, and the limit of the first fixing member 122 is achieved through the head.

The vacuum pump 20 drives the first fixing member 122 to vibrate when vibrating, and then the first fixing member 122 abuts against the first elastic member 121 to elastically deform the first elastic member 121, so that the vibration of the vacuum pump 20 is damped through the elastic deformation of the first elastic member 121.

Referring to fig. 5 to fig. 7, in some embodiments, the first elastic member 121 includes a first elastic portion 1211 and a second elastic portion 1212, and the first elastic portion 1211 and the second elastic portion 1212 may be integrally formed together, so as to ensure structural stability of the first elastic member 121.

Specifically, the first elastic portion 1211 and the second elastic portion 1212 are sequentially arranged in the height direction of the first elastic member 121, and the height direction of the first elastic member 121 may be perpendicular to the mounting plate 111. The first elastic portions 1211 and the second elastic portions 1212 are arranged at intervals such that a first annular engaging groove 1213 is formed between the first elastic portions 1211 and the second elastic portions 1212. A first connecting portion 1214 may be disposed between the first elastic portion 1211 and the second elastic portion 1212, where the first connecting portion 1214 connects the first elastic portion 1211 and the second elastic portion 1212, and at this time, an outer wall of the first connecting portion 1214 forms a bottom wall of the first annular engaging groove 1213.

In combination with the above, the through hole formed in the first elastic member 121 for the first fixing member 122 to pass through is a first through hole 1215, and the first through hole 1215 passes through the middle parts of the first elastic portion 1211, the connecting portion, and the second elastic portion 1212.

With the above configuration, for the specific mounting manner of the first elastic member 121, the mounting plate 111 is provided with the first mounting hole 113, the first annular engaging groove 1213 is engaged at the first mounting hole 113, the bottom of the first elastic portion 1211 abuts against the top wall of the mounting plate 111, and the top of the second elastic portion 1212 abuts against the bottom wall of the mounting plate 111. At this time, the bottom wall of the first annular engaging groove 1213 may abut against the inner wall of the first mounting hole 113, and the upper wall of the first annular engaging groove 1213 may abut against the top wall of the mounting plate 111, that is, the bottom wall of the first elastic portion 1211 abuts against the top wall of the mounting plate 111; the lower wall of the first annular engaging groove 1213 abuts against the bottom wall of the mounting plate 111, that is, the top wall of the mounting plate 111 abuts against the abutment wall of the second elastic portion 1212.

Based on the arrangement of the first annular clamping groove 1213, the first elastic member 121 is fixed on the mounting plate 111 in a clamping manner, so that the first elastic member 121 is convenient to split. Further, the first elastic portion 1211 and the second elastic portion 1212 are brought into contact with the top wall and the bottom wall of the mounting plate 111, respectively. At this time, when the first fixing member 122 vibrates, a good shock absorbing effect can be achieved by the elastic deformation of the first elastic portion 1211 and the second elastic portion 1212.

Fig. 8 is a sectional view of the structure of fig. 2 taken along a section line C-C, fig. 9 is a schematic structural view of the second elastic member 131 of fig. 3, fig. 10 is a schematic structural view of the second elastic member 131 of fig. 9 at another view angle, and fig. 11 is a sectional view of the second elastic member 131 of fig. 10 taken along a section line D-D.

Referring to fig. 3 and 8-11, in some embodiments, the second shock absorbing structure 13 includes a second elastic member 131 and a second fixing member 132, where the second fixing member 132 passes through the second elastic member 131 and the mounting arm 112.

Specifically, the second elastic member 131 may be provided with a second through hole 1311, and the second through hole 1311 is used for passing through the second fixing member 132. At this time, the mounting arm 112 may be provided with a through hole, and the second elastic member 131 may be disposed at the through hole, and the second fixing member 132 passes through the mounting arm 112 when passing through the second through hole 1311 of the second elastic member 131. The second fixing member 132 is fixed to the vehicle body fixing structure 21 by its top portion while the second elastic member 131 is mounted and carried by its bottom portion. The second fixing member 132 supports the mounting arm 112 by the second elastic member 131 when the mounting arm 112 is supported at least in part by the second elastic member 131.

In combination with the above, since the mounting arm 112 is supported on the second elastic member 131, the mounting arm 112 vibrates when the vacuum pump 20 vibrates, and thus the second elastic member 131 is elastically deformed by the mounting arm 112, so that the vibration of the mounting bracket 11 is damped by the second elastic member 131.

With continued reference to fig. 8-11, in some embodiments, the second elastic member 131 includes a third elastic portion 1312 and a fourth elastic portion 1313 arranged along a height direction thereof, and the third elastic portion 1312 and the fourth elastic portion 1313 may be connected by a second connection portion 1314.

At this time, when the mounting arm 112 vibrates up and down, the mounting arm 112 presses the third elastic portion 1312 and the second elastic portion 1212, so that the third elastic portion 1312 and the fourth elastic portion 1313 elastically deform, and the third elastic portion 1312 and the fourth elastic portion 1313 combine to absorb shock of the mounting arm 112.

For the specific shapes of the first elastic portion 1211, the second elastic portion 1212, the third elastic portion 1312, and the fourth elastic portion 1313, the second elastic portion 1212 may be arranged in a conical shape to reduce the arrangement material, and the first elastic portion 1211, the third elastic portion 1312, and the fourth elastic portion 1313 may be arranged in a columnar shape.
