For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0052] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0053] The present embodiment relates to a compressor mounting bracket, which serves as a mounting carrier of a compressor 2 and can be connected to a vehicle frame 3, so that the compressor 2 is mounted on the vehicle frame 3. The compressor mounting bracket of the present embodiment aims to optimize its own structure to solve the problem in the prior art that the vibration energy and operating noise of the compressor 2 are large, which affects the NVH performance of the vehicle.

[0054] In terms of overall structure, the compressor mounting bracket of this embodiment includes a bracket body 1 and a suspension bushing 100 disposed on the bracket body 1. The bracket body 1 has a mounting portion for mounting the compressor 2, and the bracket body 1 can be connected to the vehicle frame 3 through the suspension bushing 100, and the suspension bushing 100 includes a cylinder sleeve 101 disposed in the bracket body 1, an inner core 103 disposed in the cylinder sleeve 101, and a rubber main spring 102 disposed between the cylinder sleeve 101 and the inner core 103.

[0055] Among them, a first limiting portion is provided between the cylinder sleeve 101 and the rubber main spring 102, and the first limiting portion is used to limit the axial displacement of the rubber main spring 102 along the inner core 103, and / or, a second limiting portion is provided between the inner core 103 and the rubber main spring 102, and the second limiting portion is used to limit the axial displacement of the rubber main spring 102 along the inner core 103.

[0056] The compressor mounting bracket described in this embodiment can limit the axial displacement of the rubber main spring 102 along the inner core 103 by setting the first limit portion and / or the second limit portion, thereby preventing excessive stretching of the rubber main spring 102, which is beneficial to improving the shock absorption, durability and creep resistance of the suspension bushing 100, thereby helping to reduce the transmission of the vibration energy and operating noise of the compressor 2 into the vehicle, and further helping to improve the NVH performance of the vehicle.

[0057] Based on the above overall introduction, the structure of the compressor mounting bracket in the present embodiment when in use is as follows: Figures 1 to 3 As shown in the figure, the structure of the compressor mounting bracket is as follows Figure 4 and Figure 5 The compressor 2 is mounted on the bracket body 1 and is mounted on the frame 3 by connecting the bottom of the bracket body 1 with the frame 3. The suspension bushing 100 is the key to improving the performance of the compressor mounting bracket. Figures 6 to 12 The structure of the suspension bushing 100 will be described.

[0058] In the suspension bushing 100 of this embodiment, the cylinder sleeve 101 and the inner core 103 are vulcanized together through the rubber main spring 102 therebetween, and are mounted on the bracket body 1 through the cylinder sleeve 101. The fastener 5 passes through the middle of the inner core 103 and is connected to the frame 3, so that the compressor mounting bracket is mounted on the frame 3. The vibration energy and operating noise transmitted from the compressor 2 or the frame 3 can be transmitted to the suspension bushing 100. At this time, the rubber main spring 102 is limited by the first limiting portion and / or the second limiting portion, and will not cause displacement along the axial direction of the inner core 103, and thus will not cause the problem of excessive stretching.

[0059] As a preferred embodiment, Figures 9 to 11 As shown in , the first limiting portion in this embodiment includes a first limiting groove 1011 provided on the inner wall of the cylinder sleeve 101, and a first limiting protrusion 1021 provided on the rubber main spring 102, and the first limiting protrusion 1021 is inserted into the first limiting groove 1011. Here, the first limiting groove 1011 and the first limiting protrusion 1021 have simple structures and are easy to process and form, and a good limiting effect can be achieved by inserting the first limiting protrusion 1021 into the first limiting groove 1011.

[0060] The first limiting protrusion 1021 is preferably arranged along the circumference of the rubber main spring 102 and is annular, and the first limiting groove 1011 is also arranged along the circumference of the cylinder sleeve 101 and is annular, which is conducive to further increasing the contact area between the two, thereby improving the limiting effect of the first limiting part. In this embodiment, the first limiting protrusion 1021 is specifically formed by being embedded in the first limiting groove 1011 during the vulcanization molding of the rubber main spring 102.

[0061] In order to further improve the limiting effect of the first limiting part, a plurality of first limiting grooves 1011 are arranged at intervals along the axial direction of the cylinder sleeve 101, and the first limiting protrusions 1021 are arranged one by one corresponding to the first limiting grooves 1011. Such an arrangement can form multiple limits in the axial direction of the cylinder sleeve 101, thereby further improving the limiting effect of the first limiting part and preventing the rubber main spring 102 from being displaced along the axial direction of the inner core 103 during use.

[0062] As a preferred embodiment, Figures 10 to 12 As shown in , the second limiting portion in this embodiment includes a second limiting groove 1031 provided on the outer wall of the inner core 103, and a second limiting protrusion 1022 provided on the rubber main spring 102, and the second limiting protrusion 1022 is inserted into the second limiting groove 1031. The second limiting protrusion 1022 is specifically formed by being embedded in the second limiting groove 1031 during the vulcanization molding of the rubber main spring 103, so that the second limiting protrusion 1022 is constrained in the second limiting groove 1031.

[0063] The structure of the second limiting groove 1031 and the second limiting protrusion 1022 here also has the advantages of being easy to process and form, and having a good limiting effect. The second limiting protrusion 1022 is preferably arranged along the circumference of the rubber main spring 102 and is annular, and the second limiting groove 1031 is also arranged along the circumference of the inner core 103 and is annular, which is conducive to further increasing the contact area between the two, thereby improving the limiting effect of the second limiting part.

[0064] like Fig.12 As shown in the figure, the second limiting grooves 1031 in this embodiment are multiple and spaced along the axial direction of the inner core 103, and the second limiting protrusions 1022 are arranged one by one in correspondence with the second limiting grooves 1031. The arrangement of multiple second limiting grooves 1031 and second limiting protrusions 1022 can form multiple limits in the axial direction of the inner core 103, thereby further improving the limiting effect of the second limiting part and preventing the rubber main spring 102 from being displaced along the axial direction of the inner core 103 during use. It can be understood that in specific implementation, the number of the first limiting grooves 1011 and the second limiting grooves 1031 can be adaptively adjusted according to the use requirements, and is not limited to the number shown in the figure.

[0065] In this embodiment, the first limiting portion and the second limiting portion cooperate to constrain both the inner and outer sides of the rubber main spring 102, which is beneficial to further enhance the limiting effect on the axial movement of the rubber main spring 102 along the inner core 103, thereby preventing the rubber main spring 102 from being over-stretched to the greatest extent, thereby helping to improve the shock absorption, durability and creep resistance of the suspension bushing 100, reduce the transmission of vibration energy and operating noise between the compressor 2 and the frame 3, and thus help to improve the NVH performance of the vehicle.

[0066] It should be noted that in addition to providing both the first limit portion and the second limit portion, only the first limit portion or only the second limit portion may be provided in this embodiment. In this case, the shock absorption, durability and creep resistance of the suspension bushing 100 can also be improved.

[0067] In addition, in order to improve the connection strength between the cylinder sleeve 101 and the bracket body 1, the formed suspension bushing 100 in this embodiment is preferably installed on the bracket body 1 by vulcanizing the cylinder sleeve 101 and the bracket body 1 together, which is also conducive to improving the assembly efficiency. As a preferred embodiment, Figure 6 As shown in FIG. 1 , a first groove 1012 is provided on the outer wall of the cylinder sleeve 101, and the bracket body 1 has a structure that is embedded in the first groove 1012 during the vulcanization molding process. A mounting hole corresponding to the cylinder sleeve 101 is formed on the bracket body 1, and a first protrusion 112 embedded in the first groove 1012 is formed on the inner wall of the mounting hole.

[0068] like Figure 7 As shown in the figure, in this embodiment, the first grooves 1012 are arranged in a plurality of intervals along the axial direction of the cylinder sleeve 101, and the first protrusions 112 are arranged one by one in correspondence with the first grooves 1012. Here, the plurality of first protrusions 112 and the corresponding first grooves 1012 cooperate with each other to form multiple limit positions in the axial direction of the cylinder sleeve 101, thereby facilitating the cylinder sleeve 101 from being displaced in the axial direction of the cylinder sleeve 101 during use. In a specific implementation, in addition to two, the number of the first grooves 1012 can also be adaptively increased according to the use requirements.

[0069] As a preferred structural example, Figure 7 and Figure 8 As shown in , the suspension bushing 100 in this embodiment includes a first bushing 40 provided at the bottom of the bracket body 1, and a second bushing 50 provided at the side of the bracket body 1. Among them, the first bushing 40 can be connected to the frame 3 in the up-down direction of the whole vehicle, and the second bushing 50 can be connected to the frame 3 in the front-back direction of the whole vehicle. With such an arrangement, the bracket body 1 can be connected to the frame 3 in multiple directions, which can improve the connection firmness between the bracket body 1 and the frame 3. During the specific installation, the fasteners 5 such as bolts can pass through the inner core 103 and be screwed to the frame 3, so that the bracket body 1 is installed on the frame 3.

[0070] Continue to combine Figure 4As shown in , the bracket body 1 in this embodiment includes a bottom portion 11, a first side portion 12 extending upward from the bottom portion 11, and a second side portion 13 extending downward from the bottom portion 11. The first side portion 12 and the second side portion 13 are respectively located at two opposite sides of the bottom portion 11, the first bushing 40 is provided on the bottom portion 11, the second bushing 50 is provided on the second side portion 13, and the mounting portion is provided on the first side portion 12.

[0071] Here, the arrangement of the bottom portion 11, the first side portion 12 and the second side portion 13 is conducive to the molding of the bracket body 1 and to reducing the weight of the bracket body 1, while also being conducive to improving the installation effect of the compressor 2 on the bracket body 1 and the connection effect between the bracket body 1 and the frame 3.

[0072] Specifically, if Figure 3 and Fig.14 As shown in the figure, the bottom part 11 is extended in the left-right direction of the vehicle, and the first side part 12 and the second side part 13 are relatively arranged at the front and rear sides of the bottom part 11. Among them, the second side part 13 is located in the middle of the bottom part 11 and extends downward. For the convenience of distinguishing description, the mounting hole for mounting the first bushing 40 is called the first mounting hole 111, and the mounting hole for mounting the second bushing 50 is called the second mounting hole 131.

[0073] like Fig.14 As shown in , the first mounting holes 111 are respectively arranged at the two ends of the bottom part 11, and are arranged through in the up-down direction of the whole vehicle, and the second mounting hole 131 is arranged on the second side part 13, and is arranged through in the front-back direction of the whole vehicle. In this embodiment, the two first mounting holes 111 and the one second mounting hole 131 are arranged in a triangle, so that the triangle has the characteristic of good stability, which is beneficial to improve the connection stability between the bracket body 1 and the frame 3. At the same time, the number of suspension bushings 100 can also be reduced, thereby helping to reduce production costs. Of course, in specific implementation, the shape of the bottom part 11 and each side part and the number of suspension bushings 100 thereon can also be adaptively adjusted according to the use requirements.

[0074] like Figures 13 to 15As shown in , the compressor 2 is installed on the side of the first side portion 12 facing the bottom portion 11 through three installation parts, so that the gravity of the compressor 2 is applied to the bottom portion 11, which is conducive to improving the bearing capacity and use stability of the bracket body 1. In order to further improve the installation effect of the compressor 2 on the first side portion 12, the side of the first side portion 12 facing the compressor 2 has an arc surface wrapped around part of the compressor 2, which is conducive to improving the connection strength between the first side portion 12 and the compressor 2. Due to the setting of the arc surface, the width of the bottom of the first side portion 12 is gradually reduced in the direction from bottom to top, which is conducive to improving the connection reliability between the first side portion 12 and the bottom portion 11.

[0075] Among them, two mounting parts are located at both ends of the top of the first side portion 12, and the two mounting parts are spaced apart in the height direction of the vehicle. Another mounting part corresponding to the highest mounting part is arranged at the bottom of the first side portion 12, so that the three mounting parts are arranged in a triangle. This not only helps to improve the installation stability of the compressor 2 on the first side portion 12, but also reduces the number of parts and components, thereby helping to reduce production costs.

[0076] As a preferred embodiment, Fig.13 , Fig.16 and Fig.17 As shown in , the mounting portion described in this embodiment includes a mounting sleeve 4 provided in the bracket body 1, the mounting sleeve 4 having a threaded hole 41, and the compressor 2 can be threadedly connected to the mounting sleeve 4 through a threaded fastener 6. The mounting sleeve 4 and the threaded hole 41 thereon are provided here, which is conducive to installing the compressor 2 on the bracket body 1, and has the advantage of convenient loading and unloading, which is conducive to the maintenance of the compressor 2.

[0077] The outer contour of the cross section of the mounting sleeve 4 is polygonal, which is convenient for processing and forming, and can also prevent the mounting sleeve 4 from rotating relative to the bracket body 1 when the threaded fastener 6 is installed, thereby improving the installation effect of the threaded fastener 6. Fig.17 In addition to the hexagon shown in , it can also be a polygon such as a quadrilateral or a pentagon.

[0078] In addition, the mounting sleeve 4 in this embodiment is vulcanized together with the bracket body 1, and a groove is provided on the outer wall of the mounting sleeve 4, and part of the bracket body 1 is embedded in the groove. In order to distinguish it from the first groove 1012 mentioned above, the groove on the mounting sleeve 4 is called the second groove 42. Because the mounting sleeve 4 is vulcanized together with the bracket body 1, a third mounting hole 121 corresponding to the mounting sleeve 4 is provided on the first side portion 12 of the bracket body 1.

[0079] Among them, Fig.16As shown in the figure, the inner wall of the third mounting hole 121 has a second protrusion 127 that protrudes outward and is embedded in the second groove 42. The arrangement of the second groove 42 and the second protrusion 127 here is beneficial to improving the connection strength and molding efficiency between the mounting sleeve 4 and the bracket body 1, and is beneficial to limiting the axial displacement of the mounting sleeve 4 along the threaded hole 41, thereby helping to improve the installation firmness and use stability of the mounting sleeve 4.

[0080] In this embodiment, the second grooves 42 are arranged in a plurality of intervals along the axial direction of the installation sleeve 4, and the second protrusions 127 are arranged in a one-to-one correspondence with the second grooves 42. Here, the plurality of second protrusions 127 and the corresponding second grooves 42 cooperate with each other to form multiple limit positions in the axial direction of the installation sleeve 4, thereby further improving the installation firmness of the installation sleeve 4. In specific implementation, in addition to two, the number of the second grooves 42 can also be adaptively increased according to the use requirements. In addition, the second protrusion 127 and the second groove 42 are also preferably annular to further improve the cooperation effect between the two.

[0081] As a preferred installation method, the installation part can install the compressor 2 on the bracket body 1 along the axial direction of the second bushing 50. That is, the compressor 2 is installed on the bracket body 1 along the front and rear direction of the vehicle, which is convenient for installation operation and has good connection reliability.

[0082] In addition, the bracket body 1 in this embodiment is preferably made of nylon. Nylon material has the advantages of low cost and weight, which is conducive to the lightweight design of the compressor mounting bracket. For example, the bracket body 1 is made of PA6 nylon, which improves the impact resistance and service life of the bracket body 1.

[0083] In addition, in order to further improve the use effect of the compressor mounting bracket in this embodiment, Fig.13 As shown in the figure, a first reinforcing rib 113 is provided on the bottom surface of the bottom part 11 along the circumference of the first mounting hole 111 and arranged outside the first mounting hole 111, and a plurality of second reinforcing ribs 114 are connected to the first reinforcing rib 113 and the outside of the first mounting hole 111 in a crisscross manner. The cooperation between the first reinforcing rib 113 and the second reinforcing rib 114 is conducive to improving the structural strength of the first mounting hole 111, that is, the connection between the bracket body 1 and the frame 3. Here, the first reinforcing rib 113 and the second reinforcing rib 114 are connected, and the plurality of second reinforcing ribs 114 are connected to each other to form a plurality of geometric shapes such as quadrilaterals and triangles, which is conducive to further improving the structural strength and rigidity of the installation of the suspension bushing 100 and the vibration attenuation effect.

[0084] like Fig.14As shown in the figure, a plurality of third reinforcing ribs 115 corresponding to the top of the second mounting hole 131 are provided on the top surface of the bottom part 11, and the plurality of third reinforcing ribs 115 are arranged at intervals along the left-right direction of the vehicle. The third reinforcing ribs 115 here are convenient for arrangement and implementation, and are conducive to improving the structural strength at the second mounting hole 131. A fourth reinforcing rib 133 located at the periphery of the second mounting hole 131 and in an annular shape is provided on the second side part 13, and a fifth reinforcing rib 134 arranged in a horizontal and vertical staggered manner and connected to the fourth reinforcing rib 133 is also provided on the second side part 13. The coordinated arrangement of the fourth reinforcing rib 133 and the fifth reinforcing rib 134 here is conducive to further improving the structural strength and rigidity of the second mounting hole 131, as well as the vibration attenuation effect.

[0085] In addition, if Fig.14 As shown in the figure, triangular reinforcing plates 122 are respectively provided between the left and right sides of the first side portion 12 and the bottom portion 11 on the same side. The two reinforcing plates 122 are helpful to further improve the connection strength between the first side portion 12 and the bottom portion 11, as well as the structural strength and rigidity of the entire bracket body 1.

[0086] As a preferred embodiment, Fig.15 As shown in FIG. 1 , a plurality of weight-reducing grooves 123 are arranged at intervals on the side of the first side portion 12 away from the compressor 2, which is conducive to reducing the weight of the bracket body 1. The cross section of the weight-reducing groove 123 is in a "mouth" shape to facilitate processing and forming.

[0087] To ensure the structural strength of the first side portion 12, a plurality of sixth reinforcing ribs 124 are provided in the weight reducing groove 123 where the third mounting hole 121 is located, and the sixth reinforcing ribs 124 are arranged at circumferential intervals along the third mounting hole 121. The sixth reinforcing ribs 124 are extended radially along the third mounting hole 121, which is beneficial to improving the structural strength at the third mounting hole 121.

[0088] In addition, one or two seventh reinforcing ribs 125 are respectively provided in at least part of the weight-reducing groove 123. When one seventh reinforcing rib 125 is provided in the weight-reducing groove 123, the seventh reinforcing rib 125 is located on the diagonal of the entire weight-reducing groove 123, and the weight-reducing groove 123 is divided into two triangular sub-grooves. When the number of the seventh reinforcing ribs 125 in the weight-reducing groove 123 is two, the seven reinforcing ribs 125 of the two intersect and form an "X" shape, and the free ends of each seventh reinforcing rib 125 are respectively connected to the corners of the corresponding weight-reducing groove 123, and the weight-reducing groove 123 is divided into four triangular sub-grooves. The structure of the seventh reinforcing rib 125 here is simple and easy to implement, which is conducive to improving the structural strength and rigidity of the first side portion 12, and is conducive to reducing vibration transmission, so that the installation of the compressor 2 on the first side portion 12 is more stable.

[0089] In addition, an eighth reinforcing rib 126 is provided on the side of the first side portion 12 facing the compressor 2 and arranged along at least a portion of the circumference of the third mounting hole 121. Fig.14 As shown in , the eighth reinforcing rib 126 is stepped, which is easy to arrange and implement, and can also improve the structural strength and rigidity at the third mounting hole 121. It can be understood that the number, structural form and position of the above-mentioned reinforcing ribs in this embodiment can be adaptively adjusted according to the use requirements, as long as the use requirements are met.

[0090] When the compressor mounting bracket in this embodiment is in use, the vibration of the compressor 2 is transmitted to the bracket body 1, attenuated by the structural rigidity of the bracket body 1 itself, decomposed and absorbed by the suspension bushing 100, and the remaining vibration is then transmitted to the frame 3, thereby greatly reducing the vibration transmitted from the compressor 2. The attenuation transmission path of the vibration force transmitted from the ground is opposite to this.

[0091] In addition, when the vehicle experiences a large working force displacement, the excitation force is transmitted from the frame 3 to the compressor mounting bracket, and is attenuated and decomposed through the structural stiffness of the compressor mounting bracket, and part of the excitation force is transmitted to the suspension bushing 100 for attenuation. Specifically, when the suspension bushing 100 experiences a large impact in the left-right direction and the up-down direction of the vehicle, the installation of the compressor 2 can limit the displacement of the rubber main spring 102 in the suspension bushing 100 along the axial direction of the inner core 103, prevent the rubber main spring 102 from being stretched excessively, and limit the rubber main spring 102 to a reasonable working range.

[0092] When a large impact occurs in the front-to-rear direction of the vehicle, the cylinder liner 101 and the inner core 103 can cooperate to effectively limit the displacement of the rubber main spring 102 in the front-to-rear direction of the vehicle, and control the displacement of the rubber main spring 102 within a reasonable working range, thereby improving the durability and creep resistance of the rubber main spring 102 in the suspension bushing 100.

[0093] The compressor mounting bracket in this embodiment optimizes the structure of the bracket body 1 and the suspension bushing 100, so that the compressor 2 can be installed on the bracket body 1 through three mounting sleeves 4, and the bracket body 1 can be installed on the frame 3 through three suspension bushings 100. It has the advantages of simple installation operation and easy implementation. It is also beneficial to reduce the transmission of compressor 2 vibration into the vehicle, thereby improving the NVH performance of the vehicle.

[0094] In addition, the present embodiment also relates to a vehicle, on which the compressor mounting bracket as described above is provided.

[0095] The vehicle described in this embodiment can reduce the vibration energy transmission and operating noise of the compressor 2 by providing the compressor mounting bracket as described above, thereby helping to improve the NVH performance and comfort of the vehicle.

[0096] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
