Description

Technical Field

[0001] The present application relates to the technical field of vehicle compressor brackets, and in particular to a high-modal nylon vehicle compressor bracket. Background Art

[0002] The vehicle air-conditioning compressor is used to drive the cooling medium in the vehicle air-conditioning system to circulate in the air-conditioning pipes and achieve cooling or heating through the reverse Carnot cycle; however, the vehicle air-conditioning compressor will generate vibrations under high-modal operation, and the vibrations will affect the ride comfort of the vehicle body. Therefore, a compressor bracket is required to support the vehicle air-conditioning compressor and absorb the vibrations generated by the compressor.

[0003] The Chinese patent with publication number CN 221250498 U and name “Bracket for vehicle air-conditioning compressor” forms a bearing surface parallel to the horizontal plane through three non-collinear bushing assemblies to reliably support the bearing plate and the vehicle air-conditioning compressor, and limit the pitch rotation of the bearing plate and the vehicle air-conditioning compressor around the horizontal axis. The horizontal axis is the central axis of the air-conditioning compressor perpendicular to the vertical direction. At the same time, the bushing assembly has a large axial stiffness, and the vertical vibration of the vehicle air-conditioning compressor with increased vibration intensity is carried through the direction of the bushing assembly with large stiffness.

[0004] The prior art of the above patent can also realize the function of shock absorbing the air-conditioning compressor. However, when the above prior art is in use, it can only absorb the vertical vibration generated by the air-conditioning compressor. The vibrations generated by the air-conditioning compressor in other directions cannot be absorbed, so that the vibration will be transmitted to the vehicle body subframe, affecting the comfort of the vehicle. Secondly, when the vehicle air-conditioning compressor is working in a high modal state, due to the change in vibration frequency, the vibration cannot be transmitted downward, the vibration cannot be absorbed, and the vibration will be transmitted to the vehicle body subframe, affecting the comfort of the vehicle. Based on this, there is still room for improvement on the basis of the existing vehicle compressor bracket. Summary of the invention

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-10A high modal nylon vehicle compressor bracket provided in an embodiment of the present invention includes a nylon bracket 1, which is an irregular rectangular hollow structure, and an assembly groove for assembling a vehicle air-conditioning compressor is arranged inside the nylon bracket 1; an insert skeleton 2, which is arranged in the installation groove on one side of the nylon bracket 1 to improve the local stiffness of the nylon bracket 1; a buffer component 3, the number of which is at least three groups, and the multiple groups of buffer components 3 are unequally arranged on the surrounding side of the nylon bracket 1, and the buffer components 3 are used to absorb the vibration generated by the vehicle air-conditioning compressor; an adapter bracket 4, which is connected between two groups of buffer components 3 arranged similarly, and the two groups of buffer components 3 are located on the same side of the vehicle air-conditioning compressor, and the adapter bracket 4 is connected to the vehicle subframe.

[0032] In the above technical solution, the nylon bracket 1 is used to install and support the air-conditioning compressor, and the insert frame 2 can increase the local stiffness of the nylon bracket 1 to ensure that the nylon bracket 1 can meet the rigidity requirements required for high modal vibration. When the air-conditioning compressor generates high-frequency vibration, the vibration will be transmitted to the buffer component 3 through the nylon bracket 1. The buffer component 3 can absorb the vibration generated by the vehicle's air-conditioning compressor to prevent the vibration from being directly transmitted to the vehicle's subframe, thereby improving the comfort of the vehicle's passengers.

[0033] It should be noted that the vehicle air-conditioning compressor will generate vibrations in all directions when working, and the vibration is not just transmitted horizontally. Therefore, the buffer component 3 must not only bear the gravity and vertical vibration of the vehicle air-conditioning compressor, but also bear the horizontal and inclined vibrations of the vehicle air-conditioning compressor. At the same time, the buffer component 3 can be adaptively adjusted according to the vibrations generated by the air-conditioning compressor under different modes of operation to ensure that the vibrations generated by the vehicle air-conditioning compressor in all directions can be absorbed to prevent the vibrations from being transmitted to the vehicle subframe.

[0034] At the same time, the adapter bracket 4 is used to connect two groups of buffer components 3 arranged closely together. The adapter bracket 4 is directly connected to the vehicle subframe, so that the gravity and vibration borne by the two groups of buffer components 3 are transmitted to the vehicle subframe together. At the same time, the adapter bracket 4 and the vehicle air-conditioning compressor have different vibration frequencies, which reduces the possibility of resonance, thereby improving the vehicle's riding comfort.

[0035] See also Figure 1 As shown, as a preferred technical solution of this embodiment, the nylon bracket 1 is made of glass fiber and nylon base material by integrated injection molding, and the insert frame 2 is interference fit with the installation groove on one side of the nylon bracket 1.

[0036] In the above technical solution, the nylon bracket 1 formed by integrated injection molding of glass fiber and nylon substrate has a high elastic modulus, which can significantly improve the tensile strength and bending strength of the nylon bracket, while increasing its rigidity. This makes the nylon bracket more stable when bearing loads, less prone to deformation or breakage, and better than the elastic modulus of plastic, so that the nylon bracket 1 can adapt to the use requirements under different modes.

[0037] Continue reading Figure 2-5 As shown, as a preferred technical solution of this embodiment, the buffer component 3 includes: a mounting frame 31, which is a cylindrical hollow structure, and a first cavity and a second cavity that are interconnected are arranged inside the mounting frame 31, and the diameter of the first cavity is larger than the diameter of the second cavity; a bearing portion 32, which is mounted inside the first cavity, and the bearing portion 32 is configured to transmit the vibrations in all directions generated by the vehicle air-conditioning compressor downward, and a plug-in rod that cooperates with the nylon bracket 1 is arranged at the upper end of the bearing portion 32, and the bearing portion 32 is fixed to the nylon bracket 1 through the plug-in rod; an extrusion portion 33, which is mounted at the upper end of the second cavity, and the upper end of the extrusion portion 33 is connected to the bearing portion 32; a connecting frame 34, which is installed at the lower end of the second cavity, the upper end of the connecting frame 34 is connected to the lower end of the extrusion part 33, and a rubber layer is arranged at the lower end of the connecting frame 34; the resistance increasing part 35, which is installed at the upper end of the connecting frame 34, a first cavity is arranged between the upper end of the resistance increasing part 35 and the extrusion part 33, and a second cavity is arranged between the lower end of the resistance increasing part 35 and the rubber layer, the first cavity and the second cavity are both filled with buffer liquid, and the resistance increasing part 35 is configured to increase the resistance of the buffer liquid flowing from the first cavity to the second cavity; the reflux part 36, which is installed in the middle of the lower end of the extrusion part 33, and the reflux part 36 is configured to flow the buffer liquid inside the second cavity to the first cavity in one direction.

[0038] In the above technical solution, the upper end of the bearing part 32 is connected to the nylon bracket 1. When the vehicle air-conditioning compressor generates vibration during operation, the vibration will be transmitted to the bearing part 32 through the nylon bracket 1. The bearing part 32 absorbs the vibrations generated in all directions by the operation of the vehicle air-conditioning compressor and transmits the vibration vertically downward. When the vibration is transmitted to the extrusion part 33, the extrusion part 33 moves downward to squeeze the buffer liquid inside the first cavity, and the buffer liquid is squeezed into the second cavity through the resistance increasing part 35. By controlling the resistance of the buffer liquid flowing from the first cavity to the second cavity, it can adapt to the high-frequency amplitude of different modes, that is, the vibration generated by the vehicle air-conditioning compressor can just meet the resistance of the first cavity to the second cavity, so that the vibration can be completely absorbed, that is, the buffer component 3 can adapt to the vibration frequency working in different modes, prevent the vibration from being transmitted to the vehicle body subframe, and improve the riding comfort.

[0039] When the vibration is restored, that is, the bearing part 32 drives the extrusion part 33 to move upward, due to the resistance between the first cavity and the second cavity, it is difficult for the buffer liquid inside the second cavity to flow into the first cavity, which is not conducive to the rapid recovery of the vibration. At the same time, the vibration is a high-modal vibration with a high vibration frequency, which may cause the previous vibration to not be fully recovered, and the downward vibration will occur again, so that the amount of liquid flowing from the first cavity to the second cavity is greater than the reflux amount from the second cavity to the first cavity. After long-term use, the pressure inside the second cavity will be greater than the pressure inside the first cavity, which will cause the vibration to be unable to be transmitted downward and absorbed. The vibration will be transmitted to the vehicle body subframe, affecting the comfort of the vehicle.

[0040] Therefore, a reflux portion 36 is installed between the first cavity and the second cavity. When the vibration is restored, the buffer inside the second cavity can flow into the first cavity through the reflux portion 36, and the buffer inside the second cavity flows unidirectionally to the first cavity, so that the vibration can be restored quickly, which is conducive to the accurate absorption of the vibration.

[0041] See also Figure 6 As shown, as a preferred technical solution of this embodiment, the bearing part 32 includes: a support frame 321, which is a circular ring structure, and the support frame 321 is installed at the upper end of the mounting frame 31; a rubber member 322, which is installed inside the support frame 321; and a bearing platform, which is configured to support the nylon bracket 1 and absorb the vibration generated by the vehicle air-conditioning compressor.

[0042] In the above technical solution, the upper end of the supporting platform is connected to the nylon bracket 1. When the vibration generated by the vehicle air-conditioning compressor is transmitted to the supporting platform, the supporting platform can transmit the vibration in the vertical direction downward, and the rubber part 322 can absorb the vibration in other directions. At the same time, the rubber part 322 has a certain rigidity. When subjected to vibration, the rubber part 322 can also produce a certain degree of elastic deformation, thereby absorbing the vibration.

[0043] Continue reading Figure 6 As shown, as a preferred technical solution of this embodiment, the supporting platform includes a supporting plate 323 and an extrusion plate 324, the upper end of the supporting plate 323 is provided with a rotating groove, the lower end of the extrusion plate 324 is provided with a universal ball head that cooperates with the rotating groove, the lower end of the extrusion plate 324 is connected to the rubber part 322, and the lower end of the supporting plate 323 is connected to the extrusion part 33, and the extrusion plate 324 transmits the vibrations in all directions generated by the vehicle air-conditioning compressor downward to the supporting plate 323.

[0044] In the above technical solution, the support plate 323 and the extrusion plate 324 are connected by a universal ball head, that is, the upper end of the extrusion plate 324 can swing at any angle when subjected to forces in various directions. The extrusion plate 324 is connected to the upper end of the rubber member 322. When the extrusion plate 324 swings, the rubber member 322 can play a supporting and buffering role, so that the extrusion plate 324 can not only transmit the vertical downward vibration, but also absorb the vibration in various directions to prevent the vibration from being transmitted to the vehicle body subframe.

[0045] It should be noted that the swing amplitude of the extrusion plate 324 is limited by the rigidity of the rubber part 322, that is, when the vehicle air-conditioning compressor generates vibration, the rubber part 322 deforms according to the vibration amplitude, so that the vibration in the horizontal direction and the inclined direction can be completely absorbed; at the same time, since the rubber part 322 will age and fatigue damage, the swing amplitude between the extrusion plate 324 and the support plate 323 needs to be limited, that is, the swing amplitude between the extrusion plate 324 and the support plate 323 is generally 0-18°, to avoid excessive swing amplitude between the extrusion plate 324 and the support plate 323, which may cause damage to the vehicle air-conditioning compressor.

[0046] See also Figure 7 As shown, as a preferred technical solution of this embodiment, the extrusion portion 33 includes: a guide tube 331, which is installed at the upper end of the second cavity, and the guide tube 331 is evenly provided with vertically penetrating flow channels; a seal 332, which is installed at the upper end of the guide tube 331, and the seal 332 is provided with a linear bearing corresponding to the flow channel; a piston rod 333, the piston rod 333 is movably arranged inside the flow channel, and the upper end of the piston rod 333 is connected to the linear bearing.

[0047] In the above technical solution, the piston rod 333 is movably arranged inside the flow channel on the guide tube 331. When the upper end of the piston rod 333 is subjected to force, the piston rod 333 will move downward along the flow channel, and the lower end of the piston rod 333 will squeeze the buffer liquid, so that the buffer liquid can enter the second cavity from the first cavity, and the purpose of absorbing vibration is achieved through the flow of the buffer liquid.

[0048] See also Figure 8-9 As shown, as a preferred technical solution of this embodiment, the resistance increasing part 35 includes a plurality of annular plates 351 arranged in sequence, and flow holes are evenly arranged on the annular plates 351. The flow rate of the buffer liquid flowing through the internal flow holes of the annular plates 351 is adjustable.

[0049] In the above technical solution, when the buffer inside the first cavity is squeezed and moves downward, the buffer flows into the second cavity through the flow hole. The flow rate of the buffer liquid can be adjusted by changing the size of the flow hole, and then it can adapt to vibrations of different frequencies, so as to meet the use requirements under high modal operation.

[0050] See also Fig. 9 As shown, as a preferred technical solution of this embodiment, the resistance increasing part 35 also includes a driving part, and there is at least one rotatable annular plate 351 among the multiple annular plates 351 arranged in sequence, and the driving part is configured to drive the rotatable annular plate 351 to rotate.

[0051] In the above technical solution, there are multiple annular plates 351. By changing the rotation angle of the rotatable annular plate 351, the size of the flow holes between adjacent annular plates 351 can be adjusted, and then the flow rate of the first cavity flowing into the second cavity can be adjusted.

[0052] As a preferred technical solution of this embodiment, the driving part includes a driving motor and a driving gear (not shown in the drawings) installed on the output shaft of the driving motor, and a ring gear matching the driving gear is arranged on the outer circumference of the rotatable annular plate 351.

[0053] In the above technical solution, the driving motor drives the driving gear to rotate, and the driving gear can drive the rotatable annular plate 351 to rotate at an angle, thereby adjusting the flow rate of the buffer solution.

[0054] See also Fig.10 As shown, as a preferred technical solution of this embodiment, the reflux portion 36 includes a mounting frame 361 installed in the middle of the lower end of the extrusion portion 33 and a one-way valve body 362 evenly arranged on the outer circumference of the mounting frame 361, and the one-way valve body 362 is connected to the lower end of the flow channel, and the one-way valve body 362 is used to direct the buffer liquid inside the second cavity to flow unidirectionally into the first cavity.

[0055] In the above technical solution, the one-way valve body 362 is an electromagnetic valve, that is, when the extrusion part 33 moves downward, the buffer liquid inside the first cavity is squeezed into the second cavity, and the one-way valve body 362 does not open; when the extrusion part 33 returns upward, the one-way valve body 362 opens, and the buffer liquid inside the second cavity enters the first cavity through the one-way valve body 362.

[0056] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
