Description

Technical Field

[0001] The present application relates to the technical field of automobile components, and in particular to a side-mounted compressor bracket assembly. Background Art

[0002] In the design of new energy vehicles, the compressor of the air-conditioning system is a key component. Its installation position and bracket design directly affect the performance and comfort of the entire vehicle.

[0003] Due to the relatively compact size of automobiles, space for compressor installation is limited, leading some companies to consider side-mounting compressors. While this approach addresses space constraints, it also creates issues with vibration and noise transmission. The compressor generates vibrations during operation, which are transmitted directly to the vehicle body through the metal bracket, degrading the vehicle's noise, vibration, and harshness (NVH) performance and impacting passenger comfort.

[0004] In response to the above problems, relevant existing technologies such as the Chinese patent application "A side-mounted vehicle body type compressor bracket", application number: 202320147546.4, discloses a solution to the problem that the vibration and noise of the compressor are directly transmitted to the vehicle body without attenuation, which deteriorates the NVH effect of the entire vehicle. A side-mounted vehicle body type compressor bracket, including a compressor body; a bracket plate is provided on one side of the compressor body, and bushing pipe fittings are provided at the front and rear of the bracket plate. The bracket plate is connected to the vehicle body by short bolts, and the bracket plate is connected to the compressor body by long bolts. A first press-fitting hole is provided in the middle of the front side and the upper and lower parts of the rear side of the bracket plate, and a second press-fitting hole is provided at the rear end and the upper and lower parts of the front side of the bracket plate. A first limiting step is provided on the right side of the first press-fitting hole. Bushing pipe fittings and middle rubber blocks are designed at the connection between the practical bracket plate and the vehicle body for double vibration isolation, thereby reducing the vibration transmission of the compressor body to the vehicle compartment when in use.

[0005] The above-mentioned utility model reduces the transmission of vibration from the compressor body to the vehicle cabin during use by designing a vibration-isolating bushing and a middle rubber block. However, this structure still warrants further improvement to achieve even better vibration isolation, thereby enhancing the overall comfort and performance of the vehicle. Utility Model Content

[0006] The technical problem to be solved by this application is to provide a side-mounted compressor bracket assembly to further solve the problem of insufficient limit of the compressor bracket and easy collision, so as to achieve better vibration isolation effect, thereby improving the overall comfort and performance of the car.

[0007] The technical solution adopted in this application is: a side-mounted compressor bracket assembly, including a bracket, the bracket is a triangular plate structure, the two side faces of the bracket are marked as the installation side and the fixed side, and bushings are installed at the three corners of the bracket, the bushing includes an inner core that passes through the two side faces of the bracket, the first end of at least one inner core is connected to a limiting plate, the limiting plate is located on the fixed side of the bracket, the second end of the inner core extends to the installation side, the second end of the inner core is a runway-shaped structure, and a buffer pad is installed in the middle of the bracket, and the buffer pad is located on the installation side.

[0008] Compared with the prior art, the advantages of this application are that, first, the gap between the bushing of the side-mounted compressor bracket and the vehicle body is large, and the conventional rubber of the bushing cannot provide a good limiting effect. Therefore, this application designs at least one inner core to be connected to a limiting plate at the first end, so that when the compressor drives the bushing to move, the limiting plate can be used to limit the position. Secondly, the conventional bushing uses a cylindrical inner core, which rotates when the compressor bolts are installed. Since the bushing outer shell is fixed to the bracket, the rotation of the inner core will cause the rubber to be rotated and stretched, affecting the durability of the rubber. This application designs the cross-section of the second end of the inner core to have a runway-shaped structure, which is clamped by the second end of the inner core during installation to prevent the inner core from rotating during bolt installation. Thirdly, a buffer pad is installed in the middle of the bracket of this application. When the compressor reaches its extreme displacement, it contacts the buffer pad, avoiding direct contact and collision between the compressor and the metal bracket. In summary, this application effectively solves the problem of insufficient limiting and easy collision of the compressor bracket, achieving better vibration isolation effect, thereby improving the overall comfort and performance of the vehicle.

[0009] In some embodiments of the present application, an inwardly-pointing arc-shaped recess is provided in the middle portion of the mounting side of the bracket, and the buffer pad is arranged to fit the arc-shaped recess.

[0010] To further accommodate compressor installation, the bracket's mounting side features an inward-pointing, curved recess in the middle, creating a larger clearance between the bracket and the compressor. This improved vibration isolation reduces noise and vibration for passengers, enhancing ride comfort.

[0011] In some embodiments of the present application, the buffer pad is installed on the bracket through three clips passing through the bracket, a plurality of buffer ridges are provided on the surface of the buffer pad, and the buffer pad is made of rubber material.

[0012] The buffer pad is fixed to the bracket by three clips passing through the bracket, ensuring the stability of the buffer pad during use and avoiding displacement or falling off of the buffer pad due to vibration or impact, thereby improving the reliability of the overall structure.

[0013] The several cushioning ridges on the surface of the cushion effectively increase friction when in contact with the compressor, enhancing the cushion's shock absorption capacity. This design better absorbs and disperses vibrations generated by the compressor during operation, reducing the transmission of vibrations to the vehicle body.

[0014] In some embodiments of the present application, among the three bushings located at the corners of the bracket, the first ends of the inner cores of two of the bushings are connected to the limiting plate, and the mounting side portion of the bracket protrudes from the limiting plate.

[0015] That is, the mounting side of the bracket is partially protruded from the limiting plate, which can protect the limiting plate and prevent the limiting plate from direct contact and collision with the external environment, thereby affecting its use.

[0016] In some embodiments of the present application, the bracket is further provided with three mounting holes, and the three mounting holes are respectively provided close to the three bushings. In the present application, the three mounting holes are used to connect with the vehicle body to achieve the installation of the bracket.

[0017] In some embodiments of the present application, the mounting hole is a stepped hole including an outer hole and an inner hole, the diameter of the outer hole is larger than the diameter of the inner hole, the outer hole is located on the mounting side of the bracket, and the inner hole is located on the fixed side of the bracket. A protruding round tube is provided on the fixed side of the bracket, and the inner wall of the round tube constitutes the inner hole.

[0018] The stepped hole design creates a good fit between the outer hole and the inner hole, effectively increasing the connection stability between the bracket and the vehicle body and reducing loosening caused by vibration or impact.

[0019] In some embodiments of the present application, a plurality of reinforcing ribs are provided on the fixed side of the bracket, and the reinforcing ribs connect two adjacent circular tubes to form a frame of a triangular structure.

[0020] By setting up multiple reinforcing ribs, the fixed side of the bracket forms a triangular structure frame. This geometric shape can effectively disperse the load applied to the bracket, improve the strength and stability of the overall structure, and reduce the risk of deformation under high load conditions.

[0021] In some embodiments of the present application, a weight-reducing groove is provided on the fixing side or the installation side of the bracket, and reinforcing ribs are arranged in at least one weight-reducing groove.

[0022] By providing weight-reducing grooves on the mounting or installation side of the bracket, material usage can be reduced, thereby reducing the overall weight of the bracket. This helps improve vehicle energy efficiency and reduce energy consumption. Reinforcing ribs are placed within the grooves to effectively maintain the bracket's structural strength and stability. The rib design distributes the load applied to the bracket, ensuring optimal performance even under high loads.

[0023] In some embodiments of the present application, the bushing includes an inner core, an outer shell and a rubber part. The outer shell is arranged outside the inner core, and the rubber part connects the inner core and the outer shell. The top of the outer shell is provided with a circle of outward-folded flange, and the flange is a circular ring structure. The outer surface of the flange is attached with a rubber part to form a gasket. The surface of the gasket is a serrated structure, and there is a distance between the gasket surface and the limit plate.

[0024] The serrated top surface of the gasket is a regular structural design that can more evenly distribute the pressure applied to the gasket, reducing local stress concentration, thereby reducing the risk of material fatigue and damage. It also provides better deformation capacity during compression, effectively absorbing and cushioning vibrations, and improving shock absorption performance.

[0025] In some embodiments of the present application, the connection between the inner core and the limiting plate is recorded as a connecting section, and the connecting section includes a lower section connected to the inner core body, and an upper section connected to the lower section, the longitudinal section of the lower section is a rectangular structure, and the longitudinal section of the upper section is a trapezoidal structure with a top surface diameter greater than a bottom surface diameter; the limiting plate is provided with an upper hole and a lower hole connected up and down, which are adapted to the connecting section, and the lower hole is a straight hole adapted to the lower section, and the longitudinal section of the upper hole is a trapezoidal structure with a top surface diameter greater than a bottom surface diameter, and the top surface diameter of the upper hole is greater than the top surface diameter of the upper section.

[0026] This structural design facilitates assembly of the limit plate, ensuring accurate positioning through the matching of the lower hole and the lower section. Furthermore, the longitudinal cross-section of the upper hole presents a trapezoidal structure with a larger top diameter than the bottom diameter. Furthermore, the top diameter of the upper hole is larger than the top diameter of the upper section, allowing the limit plate to tilt within a certain range even when under load, enhancing product flexibility.

[0027] The above embodiments can be combined arbitrarily based on the common knowledge in this field. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The present application will be described in detail below with reference to the accompanying drawings.

[0037] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0038] A side mounted compressor bracket 1 assembly, embodiment 1 is as follows Figures 1 to 3 As shown: It includes a bracket 1, which is a triangular plate-shaped structure. The two side surfaces of the bracket 1 are marked as the installation side and the fixed side. Bushings 3 are installed at the three corners of the bracket 1. The bushing 3 includes an inner core 4 that passes through the two side surfaces of the bracket 1. The first end of at least one inner core 4 is connected to a limiting plate 5. The limiting plate 5 is located on the fixed side of the bracket 1. When the compressor drives the bushing 3 to displace, it can be limited by the limiting plate 5. The second end of the inner core 4 extends to the installation side. The second end of the inner core 4 is a runway-shaped structure. When installed, it is clamped by the second end of the inner core 4 to prevent the inner core 4 from rotating when the bolt is installed. A buffer pad 6 is installed in the middle of the bracket 1. The buffer pad 6 is located on the installation side. When the compressor reaches its limit displacement, it contacts the buffer pad 6, avoiding direct contact and collision between the compressor and the metal bracket 1.

[0039] Example 2, as Figures 1 to 4As shown, the middle portion of the mounting side of the bracket 1 is provided with an inwardly curved recess, and the cushion 6 is positioned to fit within this recess. To further accommodate compressor installation, the present application also incorporates an inwardly curved recess in the middle portion of the mounting side of the bracket 1, creating a larger clearance between the bracket 1 and the compressor. This improved vibration isolation allows passengers to experience less noise and vibration during driving, thereby enhancing ride comfort.

[0040] The buffer pad 6 is mounted on the bracket 1 via three clips 7 passing through the bracket 1. Several buffer ridges are provided on the surface of the buffer pad 6, and the buffer pad 6 is made of rubber material. The buffer pad 6 is fixed to the bracket 1 via three clips 7 passing through the bracket 1, ensuring the stability of the buffer pad 6 during use and preventing the buffer pad 6 from shifting or falling off due to vibration or impact, thereby improving the reliability of the overall structure. The several buffer ridges provided on the surface of the buffer pad 6 can effectively increase the friction when in contact with the compressor, thereby enhancing the shock absorption capacity of the buffer pad 6. This design can better absorb and disperse the vibration generated by the compressor during operation, reducing the transmission of vibration to the vehicle body.

[0041] The first ends of the inner cores 4 of two of the three bushings 3 located at the corners of the bracket 1 are connected to the limit plates 5, and the mounting side of the bracket 1 protrudes from the limit plates 5. That is, the mounting side of the bracket 1 protrudes from the limit plates 5, which protects the limit plates 5 and prevents them from direct contact and collision with the external environment, which could affect their use.

[0042] The bracket 1 is further provided with three mounting holes, which are respectively provided close to the three bushings 3. In the present application, the three mounting holes are used to connect with the vehicle body to achieve the installation of the bracket 1.

[0043] The mounting hole is a stepped hole comprising an outer hole 9 and an inner hole 10. The outer hole 9 has a larger diameter than the inner hole 10. The outer hole 9 is located on the mounting side of the bracket 1, while the inner hole 10 is located on the fixed side of the bracket 1. A protruding circular tube 11 is provided on the fixed side of the bracket 1, and the inner wall of the circular tube 11 forms the inner hole 10. The stepped hole design ensures a good fit between the outer hole 9 and the inner hole 10, effectively increasing the stability of the connection between the bracket 1 and the vehicle body and reducing loosening caused by vibration or impact.

[0044] The fixed side of the bracket 1 is provided with multiple reinforcing ribs 12, which connect two adjacent circular tubes 11 to form a triangular-shaped frame. By providing multiple reinforcing ribs 12, the fixed side of the bracket 1 forms a triangular-shaped frame. This geometric shape effectively disperses the load applied to the bracket 1, improving the strength and stability of the overall structure and reducing the risk of deformation under high load conditions.

[0045] The bracket 1 is provided with a weight-reducing groove 13 on its fixed or mounting side, with a reinforcing rib 12 positioned within at least one of these grooves. Providing these grooves effectively reduces material usage and reduces the overall weight of the bracket 1. This helps improve the vehicle's energy efficiency and reduce energy consumption. The placement of the reinforcing ribs 12 within these grooves effectively maintains the bracket 1's structural strength and stability. The design of the reinforcing ribs 12 distributes the load applied to the bracket 1, ensuring good performance even under high loads.

[0046] The rest of the content of the second embodiment is the same as that of the first embodiment.

[0047] Example 3, as Figures 3 to 6 As shown, the bushing 3 includes an inner core 4, an outer shell 15 and a rubber part 14. The outer shell 15 is sleeved on the inner core 4. The rubber part 14 connects the inner core 4 and the outer shell 15. The top of the outer shell 15 is provided with a circle of outward-folded flange, and the flange is a circular ring structure. The outer surface of the flange is attached with a rubber part 14 to form a gasket 16. The surface of the gasket 16 is a serrated structure, and there is a distance between the surface of the gasket 16 and the limit plate 5.

[0048] The serrated top surface of gasket 16 is a regular structural design that more evenly distributes the pressure applied to gasket 16, reducing local stress concentration and thus lowering the risk of material fatigue and damage. It also provides improved deformation capacity during compression, effectively absorbing and cushioning vibrations and improving shock absorption performance.

[0049] The connection between the inner core 4 and the limiting plate 5 is marked as a connecting section 17. The connecting section 17 includes a lower section 17a connected to the main body of the inner core 4 and an upper section 17b connected to the lower section 17a. The longitudinal section of the lower section 17a is a rectangular structure, and the longitudinal section of the upper section 17b is a trapezoidal structure with a top diameter larger than a bottom diameter. The limiting plate 5 is provided with an upper hole 18a and a lower hole 18b that are adapted to the connecting section 17 and connected to each other from top to bottom. The lower hole 18b is a straight hole adapted to the lower section 17a. The longitudinal section of the upper hole 18a is a trapezoidal structure with a top diameter larger than a bottom diameter, and the top diameter of the upper hole 18a is larger than the top diameter of the upper section 17b. The above structural design realizes the assembly of the limiting plate 5, and the correct positioning of the limiting plate 5 is achieved by matching the lower hole 18b with the lower section 17a. At the same time, the longitudinal section of the upper hole 18a is a trapezoidal structure with a top diameter larger than a bottom diameter, and the top diameter of the upper hole 18a is larger than the top diameter of the upper section 17b, so that the limit plate 5 also has a certain tilt range under stress, thereby improving the flexibility of the product.

[0050] The rest of the content of the third embodiment is the same as that of the first or second embodiment.

[0051] The present application has been described in detail above. Specific examples have been used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is intended only to facilitate understanding of the present application and its core concepts. It should be noted that, without departing from the principles of the present application, a number of improvements and modifications may be made to the present application by a person skilled in the art, and such improvements and modifications shall fall within the scope of protection of the claims of the present application.
