Compressor assembly, air suspension system and vehicle

Abstract

The utility model relates to the technical field of vehicles, and discloses a compressor assembly, an air suspension system and a vehicle. The limiting guide columns are connected with the compressor and arranged in the direction, close to the compressor mounting plate, of the compressor. The limiting lining is connected with the compressor mounting plate, a guide hole is formed in the limiting lining, and the limiting guide column is inserted into the guide hole in a sliding mode. When the compressor is impacted by the strong acceleration of the whole vehicle, the limiting guide columns can slide along the guide holes, so that the compressor can move close to or away from the compressor mounting plate. Due to the fact that the limiting guide column is inserted into the guide hole, the limiting bush limits the limiting guide column to move in the circumferential direction, and therefore the compressor is limited to move in the circumferential direction. Therefore, the compressor can be prevented from being collided by arranging the compressor in a small arrangement space, and the occupied installation space of the compressor is reduced.

Description

Technical Field

[0001] This application relates to the technical field of vehicles, and particularly relates to a compressor assembly, an air suspension system, and a vehicle. Background Art

[0002] Nowadays, more and more vehicles are equipped with air suspensions. An air suspension is an advanced suspension system that uses components such as air springs and adjustable damping shock absorbers to precisely adjust the vehicle height, shock absorber attenuation force, and spring elastic coefficient through an electronic control system to adapt to different road conditions and driving requirements. Among them, an air compressor is used to supply air to the air springs and shock absorbers.

[0003] The compressor is generally installed in a hanging manner, that is, the compressor is located below the compressor mounting plate. In order to reduce the vibration received by the compressor, the top of the compressor is often connected to the compressor mounting plate through a primary vibration isolation structure. This installation method causes the bottom of the compressor to shake greatly in the circumferential direction when subjected to a strong acceleration impact of the whole vehicle. To avoid the compressor from colliding, a large layout space needs to be set for the compressor, resulting in a large installation space occupied by the compressor. Summary of the Utility Model

[0004] In view of this, this application provides a compressor assembly, an air suspension system, and a vehicle to solve or improve the problem that the existing compressor occupies a large installation space due to easy large circumferential shaking.

[0005] In a first aspect, this application provides a compressor assembly, including: a compressor, a compressor mounting plate, a limit guide post, and a limit bushing; the compressor and the compressor mounting plate are connected through a shock-absorbing member, one of the compressor and the compressor mounting plate is connected to the limit guide post, and the other is connected to the limit bushing; a guide hole is provided on the limit bushing, and the extending direction of the guide hole is the same as the shock-absorbing direction of the shock-absorbing member, and the limit guide post is slidably inserted into the guide hole.

[0006] Beneficial Effects: The limit guide post is connected to the compressor and moves synchronously with the compressor. The limit bushing is connected to the compressor mounting plate. A guide hole is provided on the limit bushing. When the compressor is connected to the compressor mounting plate through a shock-absorbing member, the limit guide post is inserted into the guide hole and can slide along the guide hole. When subjected to a strong acceleration impact of the whole vehicle, the limit guide post can slide along the guide hole, enabling the compressor to move closer to or farther away from the compressor mounting plate. Since the limit guide post is inserted into the guide hole, the limit bushing restricts the circumferential movement of the limit guide post, thereby restricting the circumferential movement of the compressor. The circumferential shaking amount of the compressor is reduced, so that the compressor can be placed in a smaller layout space to avoid the compressor from colliding, reducing the installation space occupied by the compressor.

[0007] In an alternative embodiment, it further includes:

[0008] A first bracket, connected to the compressor mounting plate, and the limit bushing is connected to the first bracket.

[0009] Beneficial effect: The limit bushing is connected to the compressor mounting plate through the first bracket, without changing the structure of the compressor mounting plate.

[0010] In an alternative embodiment, it further includes:

[0011] A second bracket, connected to the compressor, and the limit guide post is connected to the second bracket.

[0012] Beneficial effect: The limit guide post is connected to the compressor through the second bracket, without changing the structure of the compressor.

[0013] In an alternative embodiment, it further includes:

[0014] A baffle, connected to the limit guide post, the baffle is located on a side of the limit bushing away from the second bracket, and the baffle is adapted to block the limit bushing from disengaging from the limit guide post.

[0015] Beneficial effect: The baffle is located on a side of the limit bushing away from the second bracket to limit the limit bushing from disengaging from the limit guide post. The limit bushing can only move between the baffle and the second bracket, thereby limiting the limit guide post to slide within a corresponding interval, preventing the limit guide post from disengaging from the limit bushing and losing the limiting effect on the compressor.

[0016] In an alternative embodiment, it further includes: A plurality of the limit guide posts and the limit bushings are respectively provided and correspond one by one.

[0017] Beneficial effect: A plurality of limit guide posts jointly limit the circumferential movement of the compressor, and the limiting effect is better.

[0018] In an alternative embodiment, the limit guide post is arranged in clearance fit with the guide hole.

[0019] Beneficial effect: The gap between the outer wall of the limit guide post and the inner wall of the guide hole is small, so as to minimize the space for the limit guide post to sway circumferentially on the premise of ensuring that the limit guide post can slide along the guide hole, and further reduce the circumferential sway amount of the compressor.

[0020] In an alternative embodiment, the shock absorber includes:

[0021] A shock absorber rod, connected to the compressor, a perforation is provided on the compressor mounting plate, and the shock absorber rod is slidably inserted into the perforation;

[0022] The support plate is connected to the shock absorber rod, and the support plate is located on the side of the compressor mounting plate away from the compressor;

[0023] An elastic member, and the support plate is connected to the compressor mounting plate through the elastic member.

[0024] Beneficial effects: When impacted by the strong acceleration of the whole vehicle, it first passes through the buffering of the elastic member and then impacts on the shock absorber rod and the compressor, reducing the impact on the compressor.

[0025] In an optional implementation manner, at least two shock-absorbing members are provided.

[0026] Beneficial effects: The compressor is shock-absorbed at at least two positions, further reducing the impact on the compressor.

[0027] In a second aspect, the present application further provides an air suspension system, including the compressor assembly described in any one of the above.

[0028] Beneficial effects: The effects brought by this air suspension system are the same as those of the compressor assembly, so they will not be elaborated here.

[0029] In a third aspect, the present application further provides a vehicle, including the air suspension system described above.

[0030] Beneficial effects: The effects brought by this vehicle are the same as those of the air suspension system, so they will not be elaborated here. Description of the Drawings

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0039] Combine the following Figures 1 to 4 , describing an embodiment of the present application.

[0040] According to an embodiment of the present application, on the one hand, a compressor assembly is provided, such as Figure 1 As shown, it includes: a compressor 6, a compressor mounting plate 7, a limiting guide column 1 and a limiting bushing 2. The compressor 6 is located at the lower side of the compressor mounting plate 7, and the compressor 6 is connected to the compressor mounting plate 7 through a shock absorbing member, so that the shock absorbing member can have a shock absorbing effect on the compressor 6 in the direction of approaching or moving away from the compressor mounting plate 7.

[0041] The limiting guide post 1 is connected to the compressor 6 and moves synchronously with the compressor 6. The limiting bushing 2 is connected to the compressor mounting plate 7, and a guide hole is provided on the limiting bushing 2. When the compressor 6 is connected to the compressor mounting plate 7 through the shock absorbing member, the extension direction of the guide hole is consistent with the shock absorbing direction of the shock absorbing member, and the extension direction of the limiting guide post 1 is consistent with the shock absorbing direction of the shock absorbing member, and the shock absorbing direction of the shock absorbing member is the direction in which the compressor moves closer to or away from the compressor mounting plate 7. At this time, the limiting guide post 1 is inserted in the guide hole and can slide along the guide hole.

[0042] With such arrangement, when the whole vehicle is subjected to a strong acceleration impact, the limit guide post 1 can slide along the guide hole, so that the compressor 6 can move along the Z axis, that is, move closer to or away from the compressor mounting plate 7, to ensure the shock absorbing effect of the shock absorbing component. At the same time, since the limit guide post 1 is inserted in the guide hole, the limit bushing 2 limits the movement of the limit guide post 1 along the X axis or the Y axis, that is, limits the circumferential movement of the limit guide post 1, thereby limiting the circumferential movement of the compressor 6. The circumferential shaking amount of the compressor 6 is reduced, so that the compressor 6 can be set in a smaller layout space to avoid collisions with the compressor 6, and the installation space occupied by the compressor 6 is reduced.

[0043] It is worth noting that the limiting bushing 2 can be selected from bushings in a commonly used primary vibration isolation structure.

[0044] In other embodiments, the limit guide post 1 can also be connected to the compressor mounting plate 7. Correspondingly, the limit bushing 2 is connected to the compressor 6. The limit guide post 1 is slidably inserted into the guide hole of the limit bushing 2, so that the limit guide post 1 can limit the circumferential movement of the limit bushing 2, and thus can also limit the circumferential movement of the compressor 6.

[0045] In some embodiments, such as Figures 1 to 4 shown, the compressor assembly further includes a first bracket 3. An installation hole is formed in the first bracket 3, and the limit bushing 2 is fixedly clamped in the installation hole, so as to fixedly connect the limit bushing 2 to the first bracket 3. The first bracket 3 is connected to the compressor mounting plate 7, so that the limit bushing 2 is connected to the compressor mounting plate 7 through the first bracket 3. When the first bracket 3 is connected to the compressor mounting plate 7, the extending direction of the guide hole on the limit bushing 2 is the same as the extending direction of the limit guide post 1, so as to ensure that when the compressor 6 is connected to the compressor mounting plate 7 through the shock absorber, the limit guide post 1 can be inserted into the guide hole on the limit bushing 2 and slide along the guide hole.

[0046] The first bracket 3 can be detachably connected to the compressor mounting plate 7. During installation, the first bracket 3 is fixedly connected to the compressor mounting plate 7 by bolts, and during disassembly, the bolts are removed. The additional first bracket 3 is used to install the limit bushing 2 without changing the structure of the compressor mounting plate 7.

[0047] It should be noted that the first bracket 3 can also be integrally and fixedly connected to the compressor mounting plate 7 to increase the overall stability. A plurality of first brackets 3 can be provided, and the plurality of first brackets 3 jointly support the limit bushing 2.

[0048] In some embodiments, such as Figures 1 to 4 shown, the compressor assembly further includes a second bracket 4. The limit guide post 1 is fixedly connected to the second bracket 4. The second bracket 4 is connected to the compressor 6, so that the limit guide post 1 is connected to the compressor 6 through the second bracket 4. When the compressor 6 is connected to the compressor mounting plate 7 through the primary shock absorption structure, the extending direction of the limit guide post 1 is the same as the shock absorption direction of the shock absorber, so that when the limit guide post 1 slides along the axial direction, the compressor 6 moves closer to or farther away from the compressor mounting plate 7 synchronously.

[0049] The second bracket 4 can be detachably connected to the compressor 6. During installation, the second bracket 4 is fixedly connected to the compressor 6 by bolts, and during disassembly, the bolts are removed. The additional second bracket 4 is used to install the limit guide post 1 without changing the structure of the compressor 6.

[0050] It should be noted that the second bracket 4 can also be integrally and fixedly connected to the compressor 6 to increase the overall stability. A plurality of second brackets 4 can be provided, and the plurality of second brackets 4 jointly support the limit guide post 1.

[0051] In an optional embodiment, if Figures 1 to 3 As shown, after the limiting bushing 2 is sleeved on the limiting guide post 1, the baffle 5 is connected to the limiting guide post 1, so that the baffle 5 is located on the side of the limiting bushing 2 away from the second bracket 4. In this way, when the limiting guide post 1 slides, the limiting bushing 2 moves relative to the limiting guide post 1. For the limiting bushing 2, when the limiting bushing 2 moves relative to the limiting guide post 1, it can only move between the baffle 5 and the second bracket 4 and cannot be separated from the limiting guide post 1. Therefore, the limiting guide post 1 is limited to slide only within the corresponding interval, preventing the limiting guide post 1 from being separated from the limiting bushing 2 and losing the limiting effect on the compressor 6.

[0052] Specifically, the first end of the limiting guide post 1 is connected to the second bracket 4, and the baffle 5 is connected to the second end of the limiting guide post 1. For the connection between the limiting guide post 1 and the second bracket 4, screws are provided at both ends of the limiting guide post 1, and a threaded hole is provided on the second bracket 4. The screw at the first end of the limiting guide post 1 is screwed into the threaded hole on the second bracket 4 and tightened, thereby connecting the first end of the limiting guide post 1 to the second bracket 4. The screw at the second end of the limiting guide post 1 passes through the baffle 5 and is then screwed with a nut to fix it, so that the baffle 5 is connected to the second end of the limiting guide post 1.

[0053] In some embodiments, the sizes of the limiting guide post 1 and the guide hole are set according to the requirements so that the limiting guide post 1 and the guide hole meet the clearance fit. In this way, under the premise of ensuring that the limiting guide post 1 can slide along the guide hole, the space for the limiting guide post 1 to swing in the circumferential direction is minimized to further reduce the amount of circumferential swing of the compressor 6, thereby further reducing the installation space occupied by the compressor 6.

[0054] In an optional embodiment, a plurality of limiting guide pillars 1 and limiting bushings 2 are respectively provided, and the limiting guide pillars 1 correspond to the limiting bushings 2 one by one, each limiting guide pillar 1 is connected to the compressor 6 and moves synchronously, and each limiting bushing 2 is connected to the compressor mounting plate 7. Each limiting guide pillar 1 is correspondingly inserted in a limiting bushing 2 and slides along the limiting bushing 2. Thus, the plurality of limiting guide pillars 1 jointly limit the circumferential movement of the compressor 6, and the limiting effect is better.

[0055] In one embodiment, the shock absorbing member includes: a shock absorbing rod 8, a support plate 9 and an elastic member 10. A bushing with a perforation is fixedly arranged on the compressor mounting plate 7, the first end of the shock absorbing rod 8 is connected to the compressor 6, and the second end of the shock absorbing rod 8 is passed through the perforation of the bushing on the compressor mounting plate 7. The axial directions of the perforation and the shock absorbing rod 8 are both the directions in which the compressor 6 approaches or moves away from the compressor mounting plate 7. In this way, the shock absorbing rod 8 moves along the perforation, so that the compressor 6 can move closer to or away from the compressor mounting plate 7.

[0056] Among them, the elastic member 10 can be a spring. The spring is sleeved from the second end of the shock absorber rod 8, and then the support plate 9 is fixedly connected to the second end of the shock absorber rod 8, so that the support plate 9 is connected to the compressor mounting plate 7 through the spring. At this time, the support plate 9 is located on the side of the compressor mounting plate 7 away from the compressor 6.

[0057] Among them, the spring can be fixedly connected to the support plate 9 or can abut against the support plate 9. The spring can be fixedly connected to the compressor mounting plate 7 or can abut against the compressor mounting plate 7.

[0058] In this way, the shock absorber rod 8, the support plate 9, the bushing and the elastic member 10 form a shock absorber. When subjected to the impact of strong acceleration of the whole vehicle, it first passes through the buffering of the elastic member 10 and then impacts on the shock absorber rod 8 and the compressor 6, so that the impact on the compressor 6 is reduced.

[0059] In a further embodiment, at least two shock absorbers are provided, and two can be provided. The two shock absorber rods 8 are respectively connected to the compressor 6, and two bushings are correspondingly provided on the compressor mounting plate 7. The shock absorber rods 8 and the bushings are in one-to-one correspondence, and a support plate 9 and an elastic member 10 are provided on each shock absorber rod 8. In this way, the shock absorber rods 8, the support plates 9, the bushings and the elastic members 10 form two groups of shock absorbers in one-to-one correspondence, which play a shock absorption role on the compressor 6 at two positions and further reduce the impact on the compressor 6.

[0060] According to an embodiment of the present application, on the other hand, an air suspension system is further provided, including any one of the above compressor assemblies. The effects brought by this air suspension system are the same as those of the compressor assembly, so they will not be elaborated here.

[0061] According to an embodiment of the present application, on yet another hand, a vehicle is further provided, including the above air suspension system. The effects brought by this vehicle are the same as those of the air suspension system, so they will not be elaborated here.

[0062] Although the embodiments of the present application are described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations all fall within the scope defined by the present application.
