The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

In addition, the technical features of the different embodiments of the present utility model described below may be combined with each other as long as they do not collide with each other.

The present application provides a compressor mounting structure, and for ease of description, the following embodiments of the compressor mounting structure are illustrated for application in a vehicle. Those skilled in the art will appreciate that any device or appliance that uses a compressor may employ the compressor mounting structure of the present application.

As shown in fig. 1 and 2, an embodiment of a compressor fixing structure according to the present application includes a bracket 10, a first vibration reducing structure 20, and a second vibration reducing structure 30. The first vibration reducing structure 20 and the second vibration reducing structure 30 are both provided on the bracket 10, and the first vibration reducing structure 20 is adapted to be connected with a mounting part, and the second vibration reducing structure 30 is adapted to be connected with the compressor 200. And the vibration damping direction of the first vibration damping structure 20 and the vibration damping direction of the second vibration damping structure 30 have a preset angle. For example, the first vibration reducing structure and the second vibration reducing structure are respectively located at different positions in the circumferential direction of the compressor, so that vibrations generated in two different directions of the circumference of the compressor can be absorbed.

In some embodiments, the mounting component may be a cross beam 100 on the vehicle, for example, the compressor may be secured below the cross beam 100 by a first vibration reduction structure 20, as shown in fig. 5. In other embodiments, the mounting member may be other members suitable for securing the compressor, and the compressor may be mounted at any one of the above, below, left, and right sides of the mounting member.

The first and second vibration reducing structures 20 and 30 may be made of an elastic material, such as rubber.

With the technical solution of the present embodiment, the compressor 200 is fixed to the bracket 10 by the second vibration reducing structure 30, and the bracket 10 is fixed below the cross member 100 of the vehicle by the first vibration reducing structure 20. Because the vibration damping direction of the first vibration damping structure 20 and the vibration damping direction of the second vibration damping structure 30 have preset angles, when the compressor operates, vibration generated in two directions of the circumference can be absorbed by the first vibration damping structure 20 and the second vibration damping structure 30 respectively, so that the NVH performance of the vehicle is greatly improved, and the comfort of the passenger cabin is ensured. Therefore, the technical scheme of the embodiment solves the defect of poor vibration reduction effect of the compressor bracket in the prior art.

It should be noted that, for convenience of description of the relative positions of the components of the compressor fixing structure in this embodiment, three directions "X", "Y" and "Z" are labeled in fig. 1. However, it will be understood by those skilled in the art that the above noted directions are not to be construed as limiting the direction in which the compressor mounting structure of the present embodiment is disposed. In some embodiments, not shown, the compressor mounting structure may also be positioned in other orientations, where the relative orientation of the various components is adjusted appropriately.

The bracket 10 as described above functions to fix the compressor 200 to the cross member 100 of the vehicle, thereby fixing the compressor 200 in the vehicle. In this embodiment, the cross member 100 is located in the front cabin of the vehicle, i.e., the bracket 10 secures the compressor 200 in the front cabin of the vehicle. Of course, in some embodiments, not shown, the cross beam 100 may be located elsewhere in the vehicle.

The bracket 10 is provided with a first vibration reducing structure 20 and a second vibration reducing structure 30, the first vibration reducing structure 20 is connected with the cross beam 100, and the second vibration reducing structure 30 is connected with the compressor 200. In operation of the compressor 200, the compressor 200 generates vibrations, a portion of which the compressor 200 transmits to the bracket 10 is absorbed by the second vibration reduction structure 30, and the remaining vibrations are absorbed by the first vibration reduction structure 20 during transmission to the cross beam 100 via the bracket 10. The first vibration reducing structure 20 and the second vibration reducing structure 30 thus achieve two-stage vibration reduction of the compressor 200, thereby greatly reducing vibration transmitted to the cross member 100 and ensuring comfort of the passenger compartment.

Further, the vibration damping direction of the first vibration damping structure 20 and the vibration damping direction of the second vibration damping structure 30 having the preset angle means that the first vibration damping structure 20 and the second vibration damping structure 30 can absorb vibration generated in both directions along the circumferential direction when the compressor 200 is started, respectively.

Taking the direction shown in fig. 1 as an example, when the compressor 200 is started, the compressor 200 generates component vibrations in the Z direction and the X direction. In the present embodiment, the first vibration damping structure 20 is capable of damping component vibrations in the Z direction, and the second vibration damping structure 30 is capable of damping component vibrations in the X direction, thereby greatly improving the vibration damping effect on the compressor 200.

In this embodiment, therefore, the damping direction of the first damping structure 20 and the damping direction of the second damping structure 30 are disposed at 90 ° (i.e., the included angle between the Z-direction and the X-direction in fig. 1).

Of course, in some embodiments, not shown, the damping direction of the first damping structure 20 and the damping direction of the second damping structure 30 may also be at other angles, such as, for example, both being disposed at 60 °, 30 °, etc. So long as the first vibration reducing structure 20 and the second vibration reducing structure 30 are enabled to reduce vibrations generated by the compressor 200 in both directions.

As shown in fig. 1 and 2, in the technical solution of the present embodiment, the bracket 10 includes a first bracket 11 and a second bracket 12 that are disposed opposite to each other, and each of the first bracket 11 and the second bracket 12 includes a side wall and a top wall. The compressor 200 is disposed between the first bracket 11 and the second bracket 12, and the top wall of the first bracket 11 and the top wall of the second bracket 12 are both located above the compressor 200, and the side walls of the first bracket 11 and the side walls of the second bracket 12 are respectively located at both sides of the compressor 200. The top wall of the first bracket 11 and the top wall of the second bracket 12 are provided with a first vibration damping structure 20, and the side walls of the first bracket 11 and the side walls of the second bracket 12 are provided with a second vibration damping structure 30.

Specifically, the first bracket 11 and the second bracket 12 are each suspended below the cross member 100, and are disposed opposite to each other along the X direction shown in fig. 1. A first vibration damping structure 20 is provided on the top wall of the first bracket 11, and the first vibration damping structure 20 suspension-connects the first bracket 11 below the cross beam 100. A first vibration dampening structure 20 is provided on the top wall of the second bracket 12 and the first vibration dampening structure 20 suspends the second bracket 12 below the cross beam 100.

As can be seen from fig. 1 and 2, the side wall of the first bracket 11 and the side wall of the second bracket 12 are disposed opposite to each other, and the compressor 200 is interposed between the side wall of the first bracket 11 and the side wall of the second bracket 12. And the side wall of the first bracket 11 and the side wall of the second bracket 12 are provided with the second vibration reducing structure 30. The second vibration reducing structure 30 on the first bracket 11 and the second vibration reducing structure 30 on the second bracket 12 are fixedly connected to both sides of the compressor 200, respectively, thereby firmly fixing the compressor 200 to the first bracket 11 and the second bracket 12.

Based on the above-described structure, the first bracket 11 and the second bracket 12 fix the compressor 200 from both sides in the X direction shown in fig. 1, respectively, and thus the bracket 10 does not occupy additionally the lower side space of the compressor 200 in the Z direction shown in fig. 1, and does not occupy additionally the front side and rear side spaces of the compressor 200 in the Y direction shown in fig. 1. Therefore, the bracket 10 of the embodiment has small occupied space, is beneficial to the arrangement of other structures in the front cabin of the vehicle, and solves the problem that the compressor brackets such as wrapping type, encircling type, stacking type and the like have large occupied space in the prior art.

Further, the first bracket 11 and the second bracket 12 fix the compressor 200 from both sides, respectively, which can increase the fixing stability of the compressor 200. Of course, in some embodiments, which are not shown, if the connection strength of the compressor 200 and the bracket 10 is sufficiently large, it is also possible to provide one bracket 10 (connected to only one side of the compressor 200) without dividing into the first bracket 11 and the second bracket 12, thereby further saving the left or right space of the compressor 200 in the X direction shown in fig. 1,

as shown in fig. 1 and 2, the first bracket 11 includes a vertical plate 111 and a horizontal plate 112 connected to each other, the horizontal plate 112 forms a top wall of the first bracket, the vertical plate 111 forms a side wall of the first bracket, a first mounting hole 113 is provided on the horizontal plate 112, a first vibration reduction structure 20 is provided in the first mounting hole 113, a second mounting hole 114 is provided on the vertical plate 111, and a second vibration reduction structure 30 is provided in the second mounting hole 114.

Specifically, both the vertical plate 111 and the horizontal plate 112 are vertically disposed, thus making the first bracket 11 an inverted "L" structure. The length of the cross plate 112 is smaller than the length of the riser 111. As will be appreciated by those skilled in the art, the cross plate 112 forms the top wall of the first bracket 11 and the riser 111 forms the side wall of the first bracket 11.

Of course, in some embodiments not shown, other angles between the risers 111 and the cross plates 112 may be provided, such as 80 °, 70 °, etc.

As can be seen from fig. 2, a first mounting hole 113 is provided on the cross plate 112, a first vibration reduction structure 20 is provided in the first mounting hole 113, and the first vibration reduction structure 20 is connected with the cross beam 100 to fix the first bracket 11 under the cross beam 100. The first vibration reduction structure 20 may be fixedly coupled within the first mounting hole 113 by bonding, fastening, and integrally molding.

Further, a sleeve is provided on the upper surface of the cross plate 112 at the position of the first mounting hole 113, and the first vibration reduction structure 20 is provided in the sleeve. On the one hand, the sleeve is able to protect the first vibration reducing structure 20; on the other hand, the sleeve can enable the upper surface of the transverse plate 112 to have a certain distance from the transverse plate 100, so that the transverse plate 112 is prevented from being damaged due to collision between the transverse plate 100 and the transverse plate 112 in the running process of the vehicle.

Further, a sleeve is also provided on the inner side surface of the riser 111 at the position of the second mounting hole 114, and the second vibration reduction structure 30 is provided in the sleeve. On the one hand, the sleeve can protect the second vibration reduction structure 30; on the other hand, the sleeve can make the thickness of the riser 111 as small as possible and the thickness of the second vibration reduction structure 30 as large as possible, while reducing the weight of the first bracket 11, ensuring the vibration reduction effect of the second vibration reduction structure 30.

Further, as can be seen from fig. 2, the first mounting hole 113 is one, and the first mounting hole 113 is located at the middle of the transverse plate 112. The second mounting hole 114 is one, and the second mounting hole 114 is located at the lower side of the riser 111. I.e. a first vibration damping structure 20 and a second vibration damping structure 30 are provided on the first bracket 11.

Of course, in some other embodiments not shown, a plurality of first vibration reducing structures 20 and second vibration reducing structures 30 may be disposed on the first bracket 11, and the number of the first mounting holes 113 and the second mounting holes 114 may be correspondingly adjusted.

As shown in fig. 2, in the technical solution of the present embodiment, the second bracket 12 includes a side plate 121 and an annular surrounding wall 122 disposed at the edge of the side plate 121. The top of annular enclosing wall 122 is provided with third mounting hole 123, is provided with first damping structure 20 in the third mounting hole 123, is provided with fourth mounting hole 124 on the curb plate 121, is provided with second damping structure 30 in the fourth mounting hole 124.

Specifically, the side plates 121 are disposed vertically, the side plates 121 form side walls of the second bracket 12, and the portions of the annular surrounding walls 122 at the upper edges of the side plates 121 form top walls of the second bracket 12.

As can be seen from fig. 2, the side panels 121 extend along the plane of YZ shown in fig. 1 and are square shaped, i.e. the side panels 121 are disposed opposite the risers 111. An annular surrounding wall 122 is provided at the edge of the side plate 121 and extends in the direction in which the riser 111 is located. The second bracket 12 thus forms a box structure open to the side, having a cross-sectional shape that is generally a "" type structure. As will be appreciated by those skilled in the art, the side panels 121 form the side walls of the second bracket and the top plane of the annular enclosure wall 122 forms the top wall of the second bracket 12.

As can be seen in fig. 2, a third mounting hole 123 is provided at the top of the annular surrounding wall 122, the first vibration reducing structure 20 is provided in the third mounting hole 123, and the first vibration reducing structure 20 is connected with the cross beam 100 to fix the second bracket 12 under the cross beam 100. The first vibration reduction structure 20 may be fixedly coupled within the third mounting hole 123 by bonding, fastening, and integrally molding.

Further, a sleeve is provided at the top of the annular surrounding wall 122 at the position of the third mounting hole 123, and the first vibration reduction structure 20 is provided in the sleeve. On the one hand, the sleeve is able to protect the first vibration reducing structure 20; on the other hand, the sleeve can enable the upper surface of the annular surrounding wall 122 to have a certain distance from the beam 100, so that the beam and the annular surrounding wall 122 are prevented from being knocked in the running process of the vehicle, and the annular surrounding wall 122 is prevented from being damaged.

Further, a sleeve is also provided at a position where the inner side surface of the side plate 121 is located at the fourth mounting hole 124, and the second vibration reduction structure 30 is provided in the sleeve. On the one hand, the sleeve can protect the second vibration reduction structure 30; on the other hand, the sleeve can make the thickness of the side plate 121 as small as possible and make the thickness of the second vibration reduction structure 30 as large as possible, ensuring the vibration reduction effect of the second vibration reduction structure 30 while reducing the weight of the second bracket 12.

Further, as can be seen from fig. 2, the number of the third mounting holes 123 is two, and the two third mounting holes 123 are located on both sides of the top of the annular surrounding wall 122, respectively. The number of the fourth mounting holes 124 is two, wherein one fourth mounting hole 124 is positioned on the upper side of one side of the side plate 121, and the other fourth mounting hole 124 is positioned on the lower side of the other side of the side plate 121. I.e. two first vibration damping structures 20 and two second vibration damping structures 30 are provided on the second support 12.

So arranged, it can be seen from fig. 5 that the three first vibration reduction structures 20 on the bracket 10 form a three-point connection fixation on the cross beam 100 (three fixation points form a triangular plane), so that the bracket 10 is fixed on the cross beam 100 more stably. As can be seen from fig. 4 and 6, the three-point connection fixation (three fixation points form a triangle plane) is formed between the bracket 10 and the compressor 200 by the three second vibration reduction structures 30, so that the fixation of the compressor 200 on the bracket 10 is more stable.

Of course, in some other embodiments not shown, the second bracket 12 may also be provided with one first vibration damping structure 20 and one second vibration damping structure 30, or a greater number of first vibration damping structures 20 and second vibration damping structures 30 may be provided, and the number of third mounting holes 123 and fourth mounting holes 124 may be correspondingly adjusted.

As can be seen in conjunction with fig. 1 and 2, the dimensions of the second bracket 12 are larger than those of the first bracket 11 in the Z-direction and Y-direction shown in fig. 1, so those skilled in the art will appreciate that the second bracket 12 serves as a primary support for the compressor 200 and the first bracket 11 serves as a secondary support for the compressor 200.

As shown in fig. 1, in the technical solution of the present embodiment, an arc-shaped avoiding portion 125 adapted to the outer contour of the compressor 200 is provided on the annular surrounding wall 122.

Specifically, since the outer contour of the compressor 200 is in a barrel structure, the arc avoidance portions 125 are disposed on two side walls of the annular surrounding wall 122 along the Y direction shown in the figure, and the side portion of the compressor 200 can be close to the arc avoidance portions 125, so that the distance between the compressor 200 and the second bracket 12 is as close as possible, and the bracket 10 is compact in structure, and the occupied space is further reduced.

Further, the arc escape portion 125 is provided at a lower side position of the second bracket 12.

As shown in fig. 1, in the technical solution of the present embodiment, a reinforcing rib 126 is provided between the side plate 121 and the annular surrounding wall 122.

Specifically, the reinforcing ribs 126 can strengthen the overall strength of the second bracket 12. The reinforcing ribs 126 are provided on the surface of the side plate 121 facing the riser 111, and the reinforcing ribs 126 extend in the Z direction described in fig. 1. The reinforcing ribs 126 are connected at both ends to the upper and lower sides of the annular surrounding wall 122, respectively. The reinforcing ribs 126 are provided in plural, and the plurality of reinforcing ribs 126 are provided at intervals along the Y direction shown in fig. 1.

In addition, each of the reinforcing ribs 126 is provided with an arc-shaped escape portion 125 so as to escape from the casing of the compressor 200.

As shown in fig. 3 and 4, in the technical solution of the present embodiment, each of the first vibration reduction structure 20 and the second vibration reduction structure 30 includes an elastic bushing 40, a through hole 41 is provided on the elastic bushing 40, and a fastener 50 is provided in the through hole 41.

The first vibration damping structure 20 and the second vibration damping structure 30 in this embodiment are substantially identical in structure, except that the second vibration damping structure 30 is slightly larger than the first vibration damping structure 20. The specific structure of the first vibration damping structure 20 and the second vibration damping structure 30 will be described with reference to the elastic bushing 40 shown in fig. 4.

As can be seen from fig. 4, the elastic bushing 40 comprises a central cylinder in which a through hole 41 is formed. The outer wall of the central cylinder is connected with an elastic lip, and the section of the elastic lip is approximately S-shaped.

Further, a fastener 50 is provided in the center tube for connection with the cross beam 100 or the compressor 200. The outer side of the resilient lip is adapted to be connected to a mounting hole (first mounting hole 113, second mounting hole 114, third mounting hole 123 or fourth mounting hole 124) of the bracket 10. The inner side of the elastic bushing 40 is fixedly connected to the cross beam 100 or the compressor 200, and the outer side of the elastic bushing 40 is fixedly connected to the bracket 10.

When the cross beam 100 or the compressor 200 shakes relative to the bracket 10, the central cylinder can shake axially relative to the elastic lip, thereby absorbing vibration and playing a shaking effect.

Further, with reference to fig. 1 and 2, the axis of the central tube of the first vibration reduction structure 20 is assembled in the Z direction shown in fig. 1, and the axis of the central tube of the first vibration reduction structure 20 is assembled in the X direction shown in fig. 1. Therefore, the first vibration damping structure 20 is capable of damping component vibrations in the Z direction, and the second vibration damping structure 30 is capable of damping component vibrations in the X direction, that is, the vibration damping direction of the first vibration damping structure 20 and the vibration damping direction of the second vibration damping structure 30 are provided at 90 °.

As shown in fig. 5 and 6, in the technical solution of the present embodiment, the fastener 50 includes a bolt, and the bolt head of the bolt has a diameter larger than the inner diameter of the through hole 41. Specifically, the elastic bushing 40 is connected to the cross beam 100 or the compressor 200 by bolts.

Specifically, in the first vibration damping structure 20, the cross member 100 is provided with a connection hole, and a pre-buried nut may be provided in the through hole 41 of the center tube. The bolts pass through the connecting holes and the through holes 41 from top to bottom and then are connected with the embedded nuts of the through holes 41, thereby achieving the effect of connecting the first vibration reduction structure 20 to the cross beam 100.

Further, for the second vibration reducing structure 30, a connection boss may be provided on the housing of the compressor 200, a screw hole may be provided on an end surface of the connection boss, and a connection bolt may be connected to the screw hole of the connection boss after passing through the through hole 41 of the center tube, thereby achieving the effect of connecting the second vibration reducing structure 30 to the compressor 200. At this time, the outer diameter of the bolt head of the bolt should be larger than the inner diameter of the through hole 41 so that the bolt head can be clamped outside the through hole 41 to prevent the bolt from being separated from the through hole 41.

Furthermore, as can be seen in connection with fig. 4, the through hole 41 is arranged eccentrically with respect to the elastic bushing 40, so that the elastic bushing 40 has a wide section and a narrow section in a direction perpendicular to the axis of the through hole 41.

So configured, one skilled in the art can, based on the test results, place the wide section closer to the location of the elastomeric bushing 40 where the vibration forces are greater, thereby enhancing the vibration damping effect.

For example, in the second vibration reducing structure 30, the vibration force applied to the lower side of the second vibration reducing structure 30 is large (the gravity will generate a downward acceleration to the rotor when the rotor rotates at a high speed) when the compressor 200 is started due to the self-gravity influence of the compressor 200, so that the width can be set at a lower position (i.e., the through hole 41 is eccentric upward).

Similarly, one skilled in the art can analyze the direction in which the vibration force of the first vibration reduction structure 20 is greater according to the actual structure, thereby determining the eccentric direction of the through hole 41.

The present application also provides a vehicle, and an embodiment of the vehicle according to the present application includes the above-described compressor fixing structure and compressor 200.

Preferably, the vehicle is an electric vehicle.
