These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0046] The inventors of this application discovered during their research that when a car travels over bumpy roads, it generates high-frequency vibrations. Besides shock absorbers and tires absorbing these vibrations, the bushings on the control arm can also absorb some of them. The stiffness of the control arm bushing mounting points is closely related to the car's vibration isolation and damping performance. Existing control arm bushing mounting point brackets have relatively weak stiffness and strength. When the road surface is bumpy, the insufficient stiffness of the brackets themselves can easily lead to local resonance, weakening the ability of the bushings installed inside the brackets to absorb and isolate vibrations. This results in ineffective vibration filtering, affecting the control arm's vibration isolation and damping performance, reducing the reliability and comfort of the car, and making the bumps more noticeable on rough roads, thus impacting the user's driving and riding experience.

[0047] In view of this, this application provides a bushing bracket and a vehicle. The bushing bracket includes a first bracket, a second bracket, and a sleeve. The first bracket includes an arc-shaped support plate, and a first support plate and a second support plate connected to both ends of the arc-shaped support plate. The second bracket includes a first extension plate, a second extension plate, and a third extension plate connected in sequence. By connecting the first support plate to the first extension plate and the second support plate to the third extension plate, a stable connection between the first bracket and the second bracket is achieved. The arc-shaped support plate and the second extension plate are arranged opposite to each other and form an installation area. By installing the sleeve in the installation area, with the opposite sides of the sleeve connected to the arc-shaped support plate and the second extension plate respectively, a stable connection between the sleeve and the first bracket and the second bracket is achieved, thereby improving the stiffness and strength of the bushing bracket and enhancing its stability and reliability. By setting up the bushing bracket, the stiffness of the bushing mounting point on the vehicle is significantly improved, thereby improving the vehicle's isolation and vibration damping performance, enhancing vehicle comfort, and improving the user's driving experience.

[0048] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0049] The following is a reference appendix. Figure 1-5 This application describes a bushing bracket provided in an embodiment for mounting bushings in a vehicle.

[0050] In a first aspect, an embodiment of this application provides a bushing support, including a first support 100, a second support 200, and a sleeve 300.

[0051] The first support 100 includes an arc-shaped support plate 120, and a first support plate 110 and a second support plate 130 connected to both ends of the arc-shaped support plate 120; the second support 200 includes a first extension plate 210, a second extension plate 220 and a third extension plate 230 connected in sequence.

[0052] The first support plate 110 is connected to the first extension plate 210, the second support plate 130 is connected to the third extension plate 230, and the arc-shaped support plate 120 and the second extension plate 220 are arranged opposite to each other and form an installation area 400.

[0053] The sleeve 300 is installed in the installation area 400, and the opposite sides of the sleeve 300 are connected to the arc-shaped support plate 120 and the second extension plate 220, respectively.

[0054] For example, along the y-direction in the attached drawing, the first support plate 110 and the second support plate 130 are positioned opposite each other, and the first extension plate 210 and the third extension plate 230 are positioned opposite each other; along the x-direction in the attached drawing, the second extension plate 220 and the arc-shaped support plate 120 are positioned opposite each other. An installation area 400 is formed between the first bracket 100 and the second extension plate 220 of the second bracket 200. The sleeve 300 is installed within the installation area 400 by connecting its opposite outer peripheral walls along the x-direction to the arc-shaped support plate 120 and the second extension plate 220, respectively. This arrangement effectively improves the stiffness and strength of the bushing bracket, thereby enhancing its stability and reliability. It allows the bushing installed within the bushing bracket to stably absorb vibrations caused by road bumps, avoiding local resonance in the vehicle due to insufficient stiffness of the bushing bracket. This significantly improves the vehicle's vibration isolation and damping effect, enhancing vehicle comfort and improving the user's driving experience.

[0055] As one feasible implementation, the arc-shaped support plate 120 and the second extension plate 220 are respectively attached to the outer peripheral walls of opposite sides of the sleeve 300.

[0056] A first region 410 is formed on a portion of the outer peripheral wall of the second extension plate 220, the first support plate 110, and the sleeve 300; a second region 420 is formed on a portion of the outer peripheral wall of the second extension plate 220, the second support plate 130, and the sleeve 300.

[0057] For example, within the installation area 400, the inner wall of the arc-shaped support plate 120 and the second extension plate 220 are respectively attached to portions of the outer peripheral wall of the sleeve 300 on opposite sides along the x-direction. This results in a larger contact area between the sleeve 300 and the first support 100 and the second support 200, making the connection between the first support 100, the second support 200, and the sleeve 300 more stable, improving the rigidity and structural stability of the bushing bracket, and enhancing its performance.

[0058] Furthermore, since the sleeve 300 is installed within the installation area 400, a first region 410 is formed by the second extension plate 220, the first support plate 110, and a portion of the outer peripheral wall of the sleeve 300, and a second region 420 is formed by the second extension plate 220, the second support plate 130, and a portion of the outer peripheral wall of the sleeve 300. The presence of the first region 410 and the second region 420 can further enhance the rigidity and strength of the bushing support.

[0059] As one feasible implementation, at least one of the two ends of the first support plate 110 along the extension direction of the sleeve 300 is provided with a first flange 111, and the first flange 111 is folded away from the position where the sleeve 300 is located.

[0060] In some embodiments, the extension direction of the sleeve 300 is the z-direction in the figures. A first flange 111 is provided on the first support plate 110, and the first flange 111 extends in the negative direction of the y-direction in the figures. For example, the first flange 111 may be provided only at the top end of the first support plate 110 along the z-direction of the sleeve 300 to improve the rigidity and strength of the first support plate 110, while also providing some protection for the sleeve 300 and the bushing of the vehicle installed within the sleeve 300. For example, the first flange 111 may be provided only at the bottom end of the first support plate 110 along the z-direction; or, refer to the figures... Figure 3 As shown, first flanges 111 are provided at both the top and bottom ends of the first support plate 110 along the z-direction. These measures can improve the rigidity and strength of the first support plate 110, and provide certain protection for the sleeve 300 and the bushing of the vehicle installed in the sleeve 300.

[0061] As one possible implementation, at least one of the two ends of the second support plate 130 along the extension direction of the sleeve 300 is provided with a second flange 131, and the second flange 131 is folded away from the position where the sleeve 300 is located.

[0062] In some embodiments, the extension direction of the sleeve 300 is the z-direction in the figures. A second flange 131 is provided on the second support plate 130, and the second flange 131 extends in the positive direction of the y-direction in the figures. For example, the second flange 131 is provided only at the top end of the second support plate 130 along the z-direction of the sleeve 300 to improve the rigidity and strength of the second support plate 130, and to provide some protection for the sleeve 300 and the bushing of the vehicle installed within the sleeve 300. For example, the second flange 131 may be provided only at the bottom end of the second support plate 130 along the z-direction; or, refer to the figures... Figure 3 Second flanges 131 are provided at both the top and bottom of the second support plate 130 along the z-direction. These measures can improve the rigidity and strength of the second support plate 130, and provide a certain degree of protection for the sleeve 300 and the bushing of the vehicle installed in the sleeve 300.

[0063] It should be noted that a first flange 111 can be provided on the first support plate 110, and a second flange 131 can be provided on the second support plate 130. The direction in which the first flange 111 faces away from the sleeve 300 is opposite to the direction in which the second flange 131 faces away from the sleeve 300; that is, the direction in which the first flange 111 faces away from the sleeve 300 is the negative direction of the y-direction in the attached figure, and the direction in which the second flange 131 faces away from the sleeve 300 is the positive direction of the y-direction. In this way, the rigidity and strength of the first support plate 110 and the second support plate 130 can be strengthened simultaneously, thereby improving the rigidity and strength of the first bracket 100 and further enhancing the stability and reliability of the bushing bracket, thus improving the vehicle's isolation and vibration reduction effect. This application does not limit the specific location and number of the first flange 111 and the second flange 131.

[0064] In other embodiments, reference is made to the appendix. Figure 2 As shown, the second support plate 130 has a third flange 134 at the end opposite to the sleeve 300 along the x-direction. The third flange 134 is folded away from the position opposite to the sleeve 300. The third flange 134 makes it easier to install the bushing bracket on the vehicle frame.

[0065] It should be noted that the ends of the first support plate 110 that are away from the sleeve 300 along the x-direction and the ends of the first extension plate 210 that are away from the sleeve 300 along the x-direction can be provided with corresponding flanges, so that the bushing bracket can be more easily installed on the vehicle frame.

[0066] As one feasible implementation, a first reinforcing part 112 is provided in the middle section of the first support plate 110 along the extension direction z of the sleeve 300. Along the extension direction perpendicular to the sleeve 300, that is, along the x direction in the figure, the first end of the first reinforcing part 112 is close to the sleeve 300, and the second end of the first reinforcing part 112 extends to the end of the first support plate 110 away from the sleeve 300.

[0067] The width of the first reinforcing part 112 on the side closer to the sleeve 300 is greater than the width of the first reinforcing part 112 on the side away from the sleeve 300.

[0068] It should be noted that both the first support 100 and the second support 200 are metal parts, such as sheet metal, which are more malleable and can be designed and modified in different shapes to meet different production needs; at the same time, they can effectively improve the strength and rigidity of the bushing support and reduce the weight of the bushing support.

[0069] In some embodiments, refer to the appendix Figure 1-3 As shown, a first reinforcing part 112 is provided on the first support plate 110, which can enhance the strength and rigidity of the first support plate 110 and effectively prevent deformation of the first support plate 110. Along the x-direction, the width of the first reinforcing part 112 on the side closer to the sleeve 300 is greater than the width of the first reinforcing part 112 on the side away from the sleeve 300, which can make the plate surface of the first support plate 110 closer to the sleeve 300 stronger and more rigid, which is more conducive to supporting and protecting the bushing of the vehicle installed in the sleeve 300, thereby achieving a better isolation and vibration reduction effect and improving the user's driving comfort.

[0070] As one feasible implementation, the second support plate 130 is provided with a second reinforcing part 132 in the middle section along the extension direction z of the sleeve 300. Along the extension direction perpendicular to the sleeve 300, that is, along the x direction in the figure, the first end of the second reinforcing part 132 is close to the sleeve 300, and the second end of the second reinforcing part 132 extends to the end of the second support plate 130 away from the sleeve 300.

[0071] The width of the second reinforcing part 132 on the side closer to the sleeve 300 is greater than the width of the second reinforcing part 132 on the side away from the sleeve 300.

[0072] In some embodiments, refer to the appendix Figure 3 As shown, a second reinforcing part 132 is provided on the second support plate 130, which can enhance the strength and rigidity of the second support plate 130 and effectively prevent deformation of the second support plate 130. Along the x-direction, the width of the second reinforcing part 132 on the side closer to the sleeve 300 is greater than the width of the second reinforcing part 132 on the side away from the sleeve 300. This allows the plate surface of the second support plate 130 closer to the sleeve 300 to have greater strength and rigidity, which is more conducive to supporting and protecting the bushing of the vehicle installed in the sleeve 300, thereby achieving a better isolation and vibration reduction effect and improving the user's driving comfort.

[0073] As one feasible implementation, the second extension plate 220 is provided with a third reinforcing part 222 in the middle section along the extension direction z of the sleeve 300. Along the extension direction perpendicular to the sleeve 300, that is, along the y direction in the figure, the first end of the third reinforcing part 222 is connected to the end of the first extension plate 210 near the sleeve 300, and the second end of the third reinforcing part 222 extends to the end of the third extension plate 230 near the sleeve 300.

[0074] In some embodiments, refer to the appendix Figure 4 As shown, a third reinforcing part 222 is provided on the second extension plate 220, which can enhance the strength and rigidity of the second extension plate 220 and effectively prevent the second extension plate 220 from deforming.

[0075] It should be noted that the reference appendix... Figure 1-2 As shown, a first reinforcing part 112 can be provided on the first support plate 110, a second reinforcing part 132 can be provided on the second support plate 130, and a third reinforcing part 222 can be provided on the second extension plate 220. This can simultaneously improve the rigidity and strength of the first bracket 100 and the second bracket 200, thereby significantly improving the rigidity and strength of the bushing bracket, resulting in better vibration isolation and damping effects, improving vehicle comfort, and enhancing the user's driving experience.

[0076] For example, the first reinforcing part 112, the second reinforcing part 132, and the third reinforcing part 222 can all be deformed parts formed by stamping sheet metal parts, and the deformation directions of the first reinforcing part 112, the second reinforcing part 132, and the third reinforcing part 222 are all opposite to the sleeve 300. The first reinforcing part 112, the second reinforcing part 132, and the third reinforcing part 222 formed by stamping can also save material usage, reduce the overall weight of the bushing bracket, and reduce costs.

[0077] For example, corresponding reinforcing parts can also be provided on the first flange 111 and the second flange 131 to improve the rigidity of the bushing bracket.

[0078] As one feasible implementation, along the extension direction perpendicular to the sleeve 300, i.e. along the x direction in the figure, the extension length of the first extension plate 210 is greater than the extension length of the third extension plate 230.

[0079] The connection area between the first extension plate 210 and the first support plate 110 is greater than the connection area between the third extension plate 230 and the second support plate 130.

[0080] In some embodiments, refer to the appendix Figure 4As shown, along the x-direction, the length of the first extension plate 210 is close to the length of the first support plate 110, and the length of the first extension plate 210 is greater than the length of the third extension plate 230. This arrangement not only improves the strength and rigidity of the second bracket 200 and the overall bushing bracket, but also reduces the impact of increased rigidity on the reliability of the fastener connection, effectively avoiding excessive rigidity. If the rigidity of the bushing bracket is too large, the installation of the bushing bracket will consume more clamping force, thereby reducing the clamping force between the bushing bracket and the vehicle frame. This may lead to instability in the connection between the bushing bracket and the frame during fatigue testing, reducing the reliability of the fastener connection.

[0081] In other embodiments, the length of the first extension plate 210 along the x-direction is equal to the length of the third extension plate 230, which can further increase the strength and rigidity of the bushing bracket, making it suitable for working scenarios requiring higher strength and rigidity.

[0082] As one feasible implementation, the first support plate 110 is provided with a first connection hole 113, and the first support plate 110 is plug-welded to the first extension plate 210 through the first connection hole 113.

[0083] For example, see attached document. Figure 3 As shown, the extension direction of the first connecting hole 113 is the z-direction. The first support plate 110 and the first extension plate 210 are connected by plug welding through the first connecting hole 113 on the first support plate 110. This welding method is relatively convenient and has high welding efficiency, which enhances the connection stability between the first support plate 110 and the first extension plate 210.

[0084] Furthermore, multiple first connecting holes 113 can be spaced apart on the first support plate 110 to improve the plug welding strength between the first support plate 110 and the first extension plate 210. For example, two first connecting holes 113 are spaced apart along the z-direction to enhance the welding strength between the first support plate 110 and the first extension plate 210 along the z-direction.

[0085] It should be noted that the extension direction of the first connecting hole 113 can be the x-direction; or multiple first connecting holes 113 can be provided at intervals along the x-direction on the first support plate 110; or multiple first connecting holes 113 can be provided at intervals along both the x-direction and the z-direction. Therefore, this application does not specifically limit the position, number, or size of the first connecting holes 113 on the first support plate 110.

[0086] In some embodiments, the first connection hole 113 is provided on the first extension plate 210, while the first support plate 110 is not provided with the first connection hole 113. The first support plate 110 and the first extension plate 210 are connected by plug welding through the first connection hole 113 on the first extension plate 210.

[0087] It should be noted that when the length of the first extension plate 210 is equal to the length of the third extension plate 230 along the x-direction, the second support plate 130 can also be provided with a first connecting hole 113. The second support plate 130 is plug-welded to the third extension plate 230 through the first connecting hole 113, thereby enhancing the connection stability between the second support plate 130 and the third extension plate 230.

[0088] As one feasible implementation, the arc-shaped support plate 120 is provided with a second connecting hole 121, and the arc-shaped support plate 120 is plug-welded to a portion of the outer peripheral wall of the sleeve 300 through the second connecting hole 121.

[0089] For example, the arc-shaped support plate 120 and the sleeve 300 are connected by plug welding through the second connecting hole 121 on the arc-shaped support plate 120, thereby enhancing the connection stability between the arc-shaped support plate 120 and the sleeve 300.

[0090] As one feasible implementation, the second extension plate 220 is provided with a third connection hole 221, and the second extension plate 220 is plug-welded to a portion of the outer peripheral wall of the sleeve 300 through the third connection hole 221.

[0091] For example, the third connecting hole 221 extends in the y direction. Through the third connecting hole 221 on the second extension plate 220, the second extension plate 220 and the sleeve 300 are plug-welded together, thereby enhancing the connection stability between the second extension plate 220 and the sleeve 300.

[0092] Furthermore, multiple third connecting holes 221 can be spaced apart on the second extension plate 220 to improve the plug welding strength between the second extension plate 220 and the sleeve 300. For example, two third connecting holes 221 are spaced apart along the z-direction to enhance the welding strength between the second extension plate 220 and the sleeve 300 along the z-direction.

[0093] It should be noted that this application does not specifically limit the location, number, or size of the third connecting hole 221 on the second extension plate 220.

[0094] As one feasible implementation, the opposite edges of the first support 100, the second support 200, and the sleeve 300 are connected in pairs by lap welding.

[0095] For example, lap welding further improves the connection stability between the first support 100, the second support 200 and the sleeve 300, thereby enhancing the welding strength of the bushing support and improving the reliability of the bushing support.

[0096] As one feasible implementation, along the extension direction of the sleeve 300, i.e. along the z-direction in the figure, the diameter of the middle section of the sleeve 300 is smaller than the diameter of the two ends of the sleeve 300; a transition fillet 301 is provided at the connection between the middle section of the sleeve 300 and the two ends of the sleeve 300.

[0097] For example, the diameters at both ends of the sleeve 300 are larger than the diameter of the middle section of the sleeve 300. This reduces the area of ​​the interference fit between the sleeve 300 and the bushing of the vehicle installed inside the sleeve 300, thus reducing the force of the interference fit. This facilitates the installation and removal of the bushing and reduces the compressive force on the bushing inside the sleeve 300 during vehicle operation, thereby improving the service life of the bushing.

[0098] Meanwhile, transition fillets 301 are provided at the connection between the middle section of the sleeve 300 and the two ends of the sleeve 300 to effectively prevent damage to the sleeve 300 due to stress concentration.

[0099] It should be noted that the diameter of one end of the sleeve 300 can be set to be larger than the diameter of the middle section and the other end of the sleeve 300. This facilitates the installation and removal of the bushing and improves its service life. That is, this application does not limit the specific structure of the variable cross-section sleeve 300, and the dimensions of other parts of the sleeve 300 can also be changed, as long as the interference fit force between the bushing and the sleeve 300 is reduced. All of these measures can improve the service life of the bushing.

[0100] As one feasible implementation, the first support plate 110 is provided with a first fastening hole 114, the second support plate 130 is provided with a second fastening hole 133, and the first extension plate 210 is provided with a first mating hole 211.

[0101] The first fastening hole 114, the first mating hole 211, and the second fastening hole 133 are opposite to each other. Fasteners pass through the first fastening hole 114, the first mating hole 211, and the second fastening hole 133, and are used to install the first bracket 100 and the second bracket 200 on the vehicle.

[0102] In some embodiments, when the length of the first extension plate 210 is close to the length of the first support plate 110 along the x-direction, and the length of the first extension plate 210 is greater than the length of the third extension plate 230, the first bracket 100 and the second bracket 200 are installed on the vehicle frame by passing fasteners through the first fastening hole 114, the first mating hole 211, and the second fastening hole 133, thereby achieving a stable connection between the bushing bracket and the vehicle frame.

[0103] In other embodiments, when the length of the first extension plate 210 along the x-direction is close to the length of the first support plate 110, and the length of the first extension plate 210 is equal to the length of the third extension plate 230, a second mating hole is provided on the third extension plate 230. Furthermore, the first fastening hole 114, the first mating hole 211, the second mating hole, and the second fastening hole 133 are opposite to each other. By passing fasteners through the first fastening hole 114, the first mating hole 211, the second mating hole, and the second fastening hole 133, the first bracket 100 and the second bracket 200 are mounted on the vehicle frame, thereby achieving a stable connection between the bushing bracket and the frame.

[0104] It should be noted that, along the x-direction, the length of the first extension plate 210 is greater than that of the third extension plate 230, but the surface of the third extension plate 230 can be provided with a second mating hole, and the second mating hole is opposite to the first mating hole 211. In this case, fasteners can pass through the first fastening hole 114, the first mating hole 211, the second mating hole, and the second fastening hole 133 to install the first bracket 100 and the second bracket 200 on the vehicle frame, thereby achieving a stable connection between the bushing bracket and the frame.

[0105] For example, a fastener could be a bolt.

[0106] As one feasible implementation, the first flange 111 has a folding dimension of 14mm-16mm away from the sleeve 300.

[0107] It should be noted that the reference appendix... Figure 3 As shown, the direction of the first flange 111 away from the sleeve 300 is the negative direction of the y direction in the attached figure; the direction of the second flange 131 away from the sleeve 300 is the positive direction of the y direction in the attached figure; A1 is the dimension of the first flange 111 along the negative direction of the y direction; A2 is the dimension of the second flange 131 along the positive direction of the y direction.

[0108] For example, the dimension A1 of the first flange 111 along the negative y direction is 14mm-16mm; specifically, the dimension can be 14mm, 14.5mm, 15mm, 15.5mm or 16mm.

[0109] As one feasible implementation, the second flange 131 has a folding dimension of 14mm-16mm away from the sleeve 300.

[0110] For example, the dimension A2 of the second flange 131 along the positive direction of the y direction is 14mm-16mm; specifically, the dimension can be 14mm, 14.5mm, 15mm, 15.5mm or 16mm.

[0111] It should be noted that if the first support plate 110 is provided with a first flange 111, and the second support plate 130 is provided with a second flange 131, the direction in which the first flange 111 faces away from the sleeve 300 is opposite to the direction in which the second flange 131 faces away from the sleeve 300. That is, the direction in which the first flange 111 faces away from the sleeve 300 is the negative direction of the y-direction in the attached figure, and the direction in which the second flange 131 faces away from the sleeve 300 is the positive direction of the y-direction. The flange dimensions of the first flange 111 and the second flange 131 can be set with corresponding reinforcing parts, such as reinforcing ribs of a certain depth, to improve the rigidity of the first flange 111 and the second flange 131, thereby further improving the rigidity of the first support plate 110 and the second support plate 130.

[0112] As one feasible implementation, the depth dimension of the first reinforcing part 112 away from the sleeve 300 is 7mm-9mm.

[0113] It should be noted that the reference appendix... Figure 3-4 As shown, B1 is the dimension of the first reinforcing part 112 in the negative direction of the y direction; B2 is the dimension of the second reinforcing part 132 in the positive direction of the y direction; and B3 is the dimension of the third reinforcing part 222 in the positive direction of the x direction.

[0114] For example, the first reinforcing part 112 can be a groove structure formed by stamping and bending the first support plate 110. The direction of the first reinforcing part 112 away from the sleeve 300 is the negative direction of the y direction in the figure. The dimension B1 of the first reinforcing part 112 along the negative direction of the y direction (i.e., the groove depth of the groove formed by the first reinforcing part 112) is 7mm-9mm; specifically, the dimension can be 7mm, 7.5mm, 8mm, 8.5mm or 9mm.

[0115] As one feasible implementation, the second reinforcing part 132 has a depth dimension of 7mm-9mm along the sleeve 300.

[0116] For example, the second reinforcing part 132 can be a groove structure formed by stamping and bending the second support plate 130. The direction of the second reinforcing part 132 away from the sleeve 300 is the positive direction of the y direction in the figure. The dimension B2 of the second reinforcing part 132 along the positive direction of the y direction (i.e., the groove depth of the groove formed by the second reinforcing part 132) is 7mm-9mm; specifically, the dimension can be 7mm, 7.5mm, 8mm, 8.5mm or 9mm.

[0117] It should be noted that if the first support plate 110 is provided with a first reinforcing part 112, and the second support plate 130 is provided with a second reinforcing part 132, the direction in which the first reinforcing part 112 is away from the sleeve 300 is opposite to the direction in which the second reinforcing part 132 is away from the sleeve 300. That is, the direction in which the first reinforcing part 112 is away from the sleeve 300 is the negative direction of the y-direction in the attached figure, and the direction in which the second reinforcing part 132 is away from the sleeve 300 is the positive direction of the y-direction. This arrangement not only improves the rigidity and strength of the first bracket 100, but also avoids interference with the installation connection between the first bracket 100 and the second bracket 200, thus preventing any impact on the assembly connection between the first bracket 100 and the second bracket 200.

[0118] As one feasible implementation, the third reinforcing part 222 has a depth dimension of 7mm-9mm along the sleeve 300.

[0119] For example, the third reinforcing part 222 can be a groove structure formed by stamping and bending the second extension plate 220. The direction of the third reinforcing part 222 away from the sleeve 300 is the positive direction of the x direction in the figure. The dimension B3 of the third reinforcing part 222 along the positive direction of the x direction (i.e., the groove depth of the groove formed by the third reinforcing part 222) is 7mm-9mm; specifically, the dimension can be 7mm, 7.5mm, 8mm, 8.5mm or 9mm.

[0120] Secondly, this application provides a vehicle including a control arm, a frame, and the aforementioned bushing bracket; a bushing is provided on the control arm, the bushing passes through the sleeve 300 of the bushing bracket, and the first bracket 100 and the second bracket 200 of the bushing bracket are both mounted on the frame.

[0121] For example, the bushing on the control arm is installed in the sleeve 300 of the bushing bracket by interference fit, so as to achieve a stable connection between the bushing and the bushing bracket; by installing the first bracket 100 and the second bracket 200 on the vehicle frame, a stable connection between the bushing bracket and the vehicle frame is achieved; in this way, the bushing on the control arm can be connected to the vehicle frame through the bushing bracket, which effectively reduces the vibration transmitted from the wheel to the vehicle frame through the control arm, enhances the comfort of the vehicle, and improves the user's driving experience.
