In order to facilitate understanding of the automotive air conditioning system provided by the embodiment of the application, an application scenario thereof is first described. The automobile air conditioning system is used for automobiles, particularly electric automobiles. When the current automobile air conditioner is assembled in an automobile, the current automobile air conditioner is fixed on a beam of the automobile through hard connection. However, when the air conditioner of the automobile is used, vibration inevitably occurs, which causes the cross beam to vibrate along with the air conditioner, and affects the NVH (Noise, vibration, harshness, noise, vibration and harshness) performance of the automobile. Therefore, the embodiment of the application provides an automobile air conditioning system for reducing the influence of air conditioning vibration on an automobile. The following detailed description is made with reference to the specific drawings and examples.

Referring to fig. 1, fig. 1 shows a schematic structural diagram of an automotive air conditioning system provided in an embodiment of the present application, which is assembled on a cross beam of an automobile. The automotive air conditioning system provided by the embodiment of the application comprises an air conditioning integrated module 10, a bracket 20 and a vibration reduction assembly 30. The air conditioner integrated module 10 includes components of an air conditioner, such as a condenser, an evaporator, and a liquid path connecting the two. The bracket 20 serves as a supporting structure to support the air conditioner integrated module 10 and serves as a connecting structure to be connected with the cross beam 100, thereby completing the lifting of the air conditioner integrated module 10. The vibration damping assembly 30 is used to provide a vibration damping function, and is connected between the bracket 20 and the cross beam 100 to reduce the influence of vibration of the air conditioner integrated module 10 on the cross beam 100.

For convenience of description, a vibration direction of the air conditioner integrated module 10, which is a lifting direction of the air conditioner integrated module 10, is defined, and upon vibration, it vibrates back and forth in the first direction illustrated in fig. 1. When vibration damping assembly 30 dampens the vibration of air conditioner integrated module 10, the direction of vibration damping is as illustrated by the double-headed arrow in fig. 1.

Referring also to fig. 2, fig. 2 shows a schematic view of a specific structure when the bracket is connected to the cross beam. When the air conditioner integrated module 10 is supported, the bracket 20 is fixedly connected with the cross beam 100 through two connection points, so that the air conditioner integrated module 10 is hoisted on the cross beam 100 to ensure the stability of the air conditioner integrated module 10. And a vibration reduction assembly 30 is provided at each connection point to reduce the influence of vibration of the air conditioner integrated module 10 on the cross beam 100.

It should be understood that the bracket 20 provided in the embodiments of the present application is not limited to a specific connection point when connected to the cross beam 100, and may use two connection points, or may use three, four, five or other different numbers of connection points. However, whether several connection points are used, vibration damping assemblies 30 are used at each connection point to damp vibration. Accordingly, the structure of the damper assembly 30 will be described below by taking the damper assembly 30 of one of the connection points as an example.

Referring to fig. 3 together, fig. 3 shows a schematic structural diagram of the bracket, the vibration reduction assembly and the cross beam provided in the embodiment of the present application when they are specifically connected. When the bracket 20 is connected with the cross beam 100, the bracket 20 is fixedly connected with the vibration damping assembly 30, and the vibration damping assembly 30 is fixedly connected with the cross beam 100, so that the bracket 20 is connected with the cross beam 100. In the embodiment of the present application, the vibration damping assembly 30 is an elastic assembly, so as to realize vibration damping of the air conditioner integrated module 10 through deformation of the vibration damping assembly 30.

With continued reference to fig. 3, the bracket 20 includes a support rod 21, and a sleeve 22 fixed to the support rod 21, wherein the sleeve 22 is sleeved on the vibration damping assembly 30 and fixedly connected with the vibration damping assembly 30. As one example, the damper assembly 30 may be directly vulcanized into the sleeve 22 to fixedly connect the damper assembly 30 with the sleeve 22 of the bracket 20, thereby enhancing the strength of the connection between the damper assembly 30 and the bracket 20. When the vibration damping assembly 30 is connected with the cross beam 100, the vibration damping assembly 30 is fixedly connected with the cross beam 100 through the threaded connecting piece 40. Specifically, the threaded connection 40 is disposed through the vibration damping assembly 30, and fixedly connects the vibration damping assembly 30 to the cross beam 100. The threaded connection 40 may be a bolt, a screw, or a bolt assembly.

Referring to fig. 4 together, fig. 4 shows a schematic structural diagram provided in an embodiment of the present application. The vibration damping assembly 30 provided in the embodiment of the present application includes a two-part structure, which is a fixing sleeve 32 and a vibration damping member 31. Wherein the fixing sleeve 32 is connected with the screw connection 40 as a connection structure; the damping element serves as a functional component of the damping assembly 30, which has a certain structural elasticity.

It should be appreciated that in the present embodiment, the fixing sleeve 32 is used as a component to be engaged with the screw coupling 40, and the vibration damping member 31 is used as a component to achieve the structural strength of the vibration damping assembly 30, so that the structural strength of the fixing sleeve 32 is greater than that of the vibration damping member 31. By way of example, the retaining sleeve 32 may be a metal piece of structural strength such as steel, iron, alloy, or the like. The damping sleeve 312 may be a rubber sleeve, a silicone sleeve, or the like having elastic properties.

During assembly, the fixing sleeve 32 is nested in the vibration damper 31 and fixedly connected with the vibration damper 31, for example, in a vulcanization mode. The outer circumference of the vibration damper 31 is connected to the bracket 20, and can be directly and fixedly connected to the sleeve 22 by vulcanization. Thereby achieving vibration reduction of the air conditioner integrated module 10 by deformation of the vibration reduction member 31. The structures of the fixing sleeve 32 and the damper 31 are described in detail below.

With continued reference to fig. 4, the retaining sleeve 32 is provided with a through hole 323 for threading the threaded connection 40 when the retaining sleeve 32 is mated with the threaded connection 40. The axial direction of the through hole 323 is parallel to the axial direction of the fixing sleeve 32, and both axes are parallel to the vibration direction of the air conditioner integrated module 10.

The screw connection 40 is a structural member for connecting the fixing sleeve 32 and the cross beam 100, so as to fixedly connect the fixing sleeve 32 and the cross beam 100. As an alternative, the threaded connection 40 provided by embodiments of the present application may employ a bolt assembly. During assembly, bolts in the bolt assembly can pass through the cross beam 100 and the fixed sleeve 32, and the fixed sleeve 32 and the cross beam 100 are clamped by matching nuts of the bolts, so that stability between the two is ensured.

As an alternative, the fixing sleeve 32 may be a cylindrical sleeve, but it should be understood that the fixing sleeve 32 provided in the embodiments of the present application may also be a different sleeve structure such as an elliptic cylinder, a polygonal cylinder, or the like.

The damping member 31 provided in the embodiment of the present application is a nested member, and includes a damping sleeve 312 and a supporting sleeve 311, which are nested. When in set-up, the support sleeve 311 is positioned on the inside and the damping sleeve 312 is positioned on the outside, i.e. the support sleeve 311 is nested within the damping sleeve 312. In addition, the support sleeve 311 and the damping sleeve 312 are fixedly connected with the damping sleeve 312 through a plurality of elastic ribs 313. Illustratively, the elastic ribs 313 are arranged along the circumferential direction of the support sleeve 311 and connect the vibration damping sleeve 312 with the support sleeve 311.

It should be understood that, in the embodiment of the present application, the elastic rib 313, the damping sleeve 312 and the supporting sleeve 311 are integrally formed, i.e. formed integrally by a vulcanization process, but other manners of integrally forming may be adopted. The above-described division of the vibration damping member 31 is named according to the functions of the respective portions of the vibration damping member 31, for convenience of description of the vibration damping member 31.

The support sleeve 311 serves as a connection structure for connection with the fixing sleeve 32. When the two are specifically connected, the supporting sleeve 311 is nested in the fixing sleeve 32 and is fixedly connected with the fixing sleeve 32, for example, the two are fixedly connected in a vulcanization mode. When the supporting sleeve 311 is nested on the fixing sleeve 32, the supporting sleeve 311 is nested outside the fixing sleeve 32, and the damping assembly 30 forms a nested structure of the fixing sleeve 32, the supporting sleeve 311 and the damping sleeve 312 from inside to outside. In addition, as for structural strength, the structural strength of the fixing sleeve 32 is greater than that of the supporting sleeve 311, so that the fixing sleeve 32 can secure the structural strength of connection when being connected with the screw connection 40. The support sleeve 311 may also have a similar shape to the fixing sleeve 32, i.e. may have a polygonal cylindrical shape, an elliptic cylindrical shape, a cylindrical shape, or a cylindrical shape.

The damping sleeve 312 serves as a connecting structure for fixedly connecting with the bracket 20. In a specific connection, the damping sleeve 312 is sleeved in the sleeve 22 of the bracket 20 and can be fixedly connected with the sleeve 22, for example, by adopting a vulcanization mode to form a fixed connection. Similarly, the damping sleeve 312 may be a polygonal cylindrical sleeve, an elliptic cylindrical sleeve, a cylindrical sleeve, or the like.

After the bracket 20 is connected with the beam 100 through the vibration reduction assembly 30, it can be seen that a fixed connection is formed between the beam 100 and the support sleeve 311, a fixed connection is formed between the bracket 20 and the vibration reduction sleeve 312, and a connection is formed between the support sleeve 311 and the vibration reduction sleeve 312 through the elastic rib 313. When the air conditioner integrated module 10 vibrates, the vibration of the air conditioner integrated module 10 can be absorbed through the elastic deformation of the elastic ribs 313, so that the vibration of the air conditioner integrated module 10 is transmitted to the cross beam 100, and the influence on a vehicle is reduced.

When the elastic rib 313 is specifically provided, the length direction of the elastic rib 313 is along the axial direction of the vibration damping jacket 312. Four elastic ribs 313 are illustrated in fig. 3, and the four elastic ribs 313 are arranged at intervals along the circumferential direction of the vibration damping sleeve 312 to provide stable support. When the air conditioner integrated module 10 is vibrated, the four elastic ribs 313 can be elastically deformed identically to ensure the stability of the air conditioner integrated module 10. However, it should be understood that the number of the elastic ribs 313 provided in the embodiment of the present application is not limited to four, but three, five, six, etc. different numbers of the elastic ribs 313 may be used, and are not illustrated in the embodiment of the present application.

In addition, when the support sleeve 311, the fixing sleeve 32, and the damper sleeve 312 are provided, the axis of the through hole 323 of the fixing sleeve 32 is parallel to the axes of the fixing sleeve 32, the damper sleeve 312, and the support sleeve 311. To ensure that the vibration direction of the vibration damping sleeve 312 relative to the support sleeve 311 is parallel to the vibration direction of the air conditioner integrated module 10 when the fixing sleeve 32 is assembled to the cross beam 100, thereby absorbing the vibration of the air conditioner integrated module 10 and reducing the influence on the cross beam. As an alternative, the through hole 323 is provided coaxially with the fixing sleeve 32, the vibration damping sleeve 312 and the supporting sleeve 311. When adopting this scheme, whole damping subassembly 30 adopts symmetrical structure to set up, and convenient processing can reduce the size of whole damping subassembly 30 simultaneously.

Referring to fig. 4 and 5 together, as an alternative, when the fixing sleeve 32 is engaged with the vibration damping member 31, a first stop shoulder 321 and a second stop shoulder 322 engaged with the support sleeve 311 are provided on the fixing sleeve 32. Illustratively, along the axial direction of the vibration damping sleeve 312, the opposite ends of the fixed sleeve 32 are respectively provided with a first limiting shoulder 321 and a second limiting shoulder 322, and when the supporting sleeve 311 is fixed on the fixed sleeve 32, the opposite ends of the supporting sleeve 311 are respectively in pressing contact with the first limiting shoulder 321 and the second limiting shoulder 322, so that the axial movement of the supporting sleeve 311 is limited by the two limiting shoulders, the connection strength of the supporting sleeve 311 and the fixed sleeve 32 is improved, and the connection stability of the supporting sleeve 311 and the fixed sleeve 32 is ensured.

When the fixing sleeve 32 is assembled with the cross beam 100, the first limiting shoulder 321 is close to the cross beam 100 and abuts against the cross beam 100. And the second stop shoulder 322 is remote from the beam 100. When the threaded connection 40 is a bolt assembly, the nut or nut of the bolt assembly can be pressed against the second limiting shoulder 322, so that the contact area is increased, and the stability of the fixing sleeve 32 is improved. Similarly, when the first limiting shoulder 321 is pressed against the beam 100, the contact area between the first limiting shoulder 321 and the beam 100 can be increased, so that the stability of the fixing sleeve 32 when being connected with the beam 100 is ensured.

As an alternative, to ensure the stability of the connection of the retaining sleeve 32 to the cross beam 100. A plurality of limiting protrusions 321a which are engaged with the cross beam 100 and limit the rotation of the fixing sleeve 32 are provided on the first limiting shoulder 321. Referring to fig. 5 and 6 together, the first stop shoulder 321 has three stop protrusions 321a disposed at an end facing the beam 100, and the three stop protrusions 321a are arranged at intervals and surround the through hole 323 of the fixing sleeve 32. Correspondingly, the cross beam 100 is provided with the limit grooves corresponding to the limit protrusions 321a one by one, after the fixing sleeve 22 is fixed on the cross beam 100, the limit protrusions 321a are clamped in the limit grooves, so that the axial rotation of the limit fixing sleeve 32 is ensured, the fixing sleeve 32 can be stably maintained at the assembling position when the threaded connecting piece 40 is used for fastening the fixing sleeve 22, the fixing sleeve 32 and the vibration damping sleeve 312 cannot rotate relatively, and the reliability of the vibration damping assembly 30 is ensured.

The vibration damping assembly 30 provided in the embodiment of the present application not only absorbs the vibration of the air conditioner integrated module 10 by using the elastic rib 313 as an elastic element, but also limits the maximum vibration amplitude of the vibration damping element 31, so as to ensure the protection of the air conditioner integrated assembly when the vehicle runs on a bumpy road.

With continued reference to fig. 5 and 6. When the second limit shoulder 322 and the damper sleeve 312 are provided, an inner circumferential edge of an end of the damper sleeve 312 adjacent to the second limit shoulder 322 is located within a circumferential edge of the second limit shoulder 322 in an axial direction of the damper sleeve 312, and a gap is provided between an end of the damper sleeve 312 adjacent to the second limit shoulder 322 and the second limit shoulder 322. As illustrated in fig. 5, the damping sleeve 312 is adjacent to a gap of a gap length J between an end of the second stop shoulder 322 and the second stop shoulder 322. As shown in FIG. 6, where the diameter of the damping sleeve is D and the diameter of the second stop shoulder 322 is D, D < D, i.e., the outer peripheral edge of the damping sleeve 312 also falls within the peripheral edge of the second stop shoulder 322. When the damper sleeve 312 moves downward (with the placement direction of the damper in fig. 5 as the reference direction) to the stationary sleeve 32 to the lowest position, the end of the damper sleeve 312 is pressed against the second limit shoulder 322 to limit the continued downward movement of the damper sleeve 312 by the second limit shoulder 322, thereby defining the maximum displacement amount of the downward movement of the damper sleeve 312. The safety of the air conditioner integrated module 10 is ensured.

Alternatively, a plurality of first spacing protrusions 312b are disposed at an end of the damping sleeve 312 adjacent to the second spacing shoulder 322 in a spaced-apart arrangement, and the plurality of first spacing protrusions 312b are disposed at intervals along the circumferential direction of the damping sleeve 312. When engaged with the second stop shoulder 322, the first stop tab 312b is spaced from the second stop shoulder 322 by a gap that is the downward movement of the damping sleeve 312. When the damping sleeve 312 moves to the first setting position, the first limit projection 312b presses against the second limit shoulder 322. To support the first limit projection 312b by the second limit shoulder 322. When the plurality of first limiting protrusions 312b are matched with the second limiting convex shoulder 322, the impact force of the vibration damping sleeve 312 in contact with the second limiting protrusion 312a can be reduced through the deformation of the first limiting protrusion 312b, and a certain buffer support is provided, so that the stability of the air conditioner integrated module 10 is ensured.

It should be appreciated that the first limiting protrusion 312b provided as described above cooperates with the elastic rib 313 to provide an elastic force to support the vibration damping sleeve 32, thereby limiting a maximum downward movement distance of the air conditioner integrated module 10 and ensuring safety of the air conditioner integrated module 10.

When the elastic ribs 313 and the first limiting protrusions 312b are specifically provided, the plurality of first limiting protrusions 312b and the plurality of elastic ribs 313 are alternately arranged along the circumferential direction of the vibration damping sleeve 312. The elastic ribs 313 are arranged at the gaps between the adjacent first limiting shoulders 321, so that the elastic ribs 313 can be matched with the first limiting protrusions 312b, and different positions of the vibration damping sleeve 312 are stressed respectively to participate in the protection of the air conditioner integrated module 10.

Similarly, in a vertically upward direction, the limit of the maximum upward movement displacement of the damping sleeve 312 is achieved by the cooperation of the damping sleeve 312 with the cross beam 100. Illustratively, the inner circumferential edge of the damping sleeve 312 facing one end of the cross beam 100 is located outwardly of the circumferential edge of the first stop shoulder 321 in the axial direction of the damping sleeve 312, i.e. the damping sleeve 312 has a dimension that is greater than the dimension of the first stop shoulder 321. When the fixing sleeve 32 is assembled to the cross beam 100, the height of the end of the vibration damping sleeve 312 facing the cross beam 100 is lower than the height of the first limit shoulder 321, and is spaced apart from the cross beam 100 by a gap. As shown in fig. 5, the height of the first stop shoulder 321 is H, and the height of the damping sleeve 312 is H, H > H is satisfied. The gap between the damping sleeve 312 and the cross beam 100 is used to satisfy the displacement of the damping sleeve 312 when absorbing the vibration of the air conditioner integrated module 10, and when the damping sleeve 312 vibrates to the maximum position, the damping sleeve 312 is in pressing contact with the cross beam 100 to limit the maximum displacement of the damping sleeve 312 moving upwards, so as to protect the air conditioner integrated module 10.

In an alternative, the damping sleeve 312 is provided with a plurality of second stopper protrusions 312a toward one end of the cross beam 100, and the plurality of second stopper protrusions 312a are spaced apart along the circumferential edge of the damping sleeve 312. When specifically arranged, the second limiting projections 312a and the elastic ribs 313 are also arranged at intervals in the axial direction of the vibration damping sleeve 312. The first limiting protrusion 312b is similar to the elastic rib 313, and will not be described herein.

The second limit projection 312a is also spaced from the cross member 100 by a gap when the fixing sleeve 32 is assembled to the cross member 100. When the damper sleeve 312 moves to the second set position, the second limit projection 312a is pressed against the cross member 100. Thereby limiting the upward maximum displacement amount of the vibration damping sleeve 312 through the cooperation of the second limit protrusion 312a and the cross beam 100, and ensuring the safety of the air conditioner integrated module 10.

As can be seen from the above description, by adopting the connection between the vibration damping sleeve 312 and the supporting sleeve 311 through the elastic rib 313, the vibration damping sleeve 312 is fixedly connected with the bracket 20, and the supporting sleeve 311 is connected with the cross beam 100 through the nested fixing sleeve 32. When the air conditioner vibrates, the deformation of the elastic ribs 313 can absorb the vibration, so that the influence of the vibration of the air conditioner integrated module 10 on the cross beam 100 is reduced, and the vibration of the vehicle is further reduced.

The embodiment of the application also provides an automobile, which comprises the cross beam 100 and the automobile air conditioning system of any one of the above; wherein the fixed sleeve 32 is fixedly connected with the cross beam 100 by a threaded connection 40.

In the above technical solution, the vibration damping sleeve 312 is connected with the supporting sleeve 311 through the elastic rib 313, the vibration damping sleeve 312 is fixedly connected with the bracket 20, and the supporting sleeve 311 is connected with the cross beam 100 through the nested fixing sleeve 32. When the air conditioner vibrates, the deformation of the elastic ribs 313 can absorb the vibration, so that the influence of the air conditioner vibration on the vibration of the cross beam 100 is reduced, and the vibration of the vehicle is further reduced.

When the fixing sleeve 32 is specifically connected to the cross beam 100, as shown in fig. 7 and 8, when the limiting protrusion 321a is provided on the fixing sleeve 32, a limiting groove that mates with the limiting protrusion 321a is correspondingly provided on the cross beam 100. Thereby the fixed sleeve 32 is axially limited, the relative rotation between the fixed sleeve 32 and the vibration damping sleeve 312 can not occur when the threaded connecting piece 40 is connected with the fixed sleeve 32 and the cross beam 100, and the reliability of the vibration damping assembly 30 is ensured.
