[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] Reference below Figure 1-Figure 3A suspension assembly 1 and a vehicle according to an embodiment of the present invention are described.

[0033] like Figure 1 and Figure 3 As shown, according to the suspension assembly 1 of the embodiment of the first aspect of the utility model, the suspension assembly 1 includes: a bracket 11 and a suspension unit 12.

[0034] Among them, the bracket 11 is formed with a mounting hole 11a; the suspension unit 12 is detachably arranged on the bracket 11, and the suspension unit 12 is assembled to the mounting hole 11a along a first direction; the suspension unit 12 is provided with a movable limiter 121 to selectively limit the movement of the suspension unit 12 relative to the bracket 11 in the first direction; the first direction intersects with the axial direction of the suspension unit 12.

[0035] Specifically, the bracket 11 can provide a mounting position for some other components (such as the suspension unit 12) in the suspension assembly 1, and can support, fix and protect some other components in the suspension assembly 1. The bracket 11 can be formed with a through mounting hole 11a; the suspension unit 12 can be assembled into the mounting hole 11a of the bracket 11 along the first direction, and the limiter 121 on the suspension unit 12 can move relative to the suspension unit 12. When the suspension unit 12 is assembled with the bracket 11, the limiter 121 can move relative to the suspension unit 12, and when the suspension unit 12 is in a preset assembly position, the suspension unit 12 is restricted from moving relative to the bracket 11 in the first direction. When the suspension unit 12 needs to be disassembled from the bracket 11, the limiter 121 can move relative to the suspension unit 12, and release the movement restriction between the suspension unit 12 and the bracket 11 in the first direction, so that the suspension unit 12 can move relative to the bracket 11 again to perform the disassembly operation.

[0036] It should be pointed out that the above-mentioned first direction intersects with the axial direction of the suspension unit 12, and the first direction and the axial direction of the suspension unit 12 may be orthogonal, for example, the axial direction of the suspension unit 12 is a vertical direction, and the first direction is a horizontal direction; the first direction and the axial direction of the suspension unit 12 may intersect, or the first direction and the axial direction of the suspension unit 12 may form a certain angle other than 90°, and the two are not orthogonal to each other.

[0037] According to the suspension assembly 1 of the utility model, the limit piece 121 on the suspension unit 12 can selectively limit the movement of the suspension unit 12 relative to the bracket 11 in the first direction, thereby improving the assembly accuracy, firmness and stability between the suspension unit 12 and the bracket 11, and increasing the convenience of disassembly and maintenance of the suspension unit 12 and the bracket 11, which is beneficial to optimizing the working performance and reliability of the suspension assembly 1, and improving the production efficiency and disassembly efficiency of the suspension assembly 1.

[0038] like Figure 1-Figure 3As shown, according to some embodiments of the present invention, the limiting member 121 includes: a first limiting portion 1211 and a second limiting portion 1212 .

[0039] Among them, the first limiting portion 1211 and the second limiting portion 1212 are respectively arranged at the two ends of the suspension unit 12 in the first direction, and the first limiting portion 1211 and the second limiting portion 1212 are suitable for abutting against the bracket 11 to limit the movement of the suspension unit 12 relative to the bracket 11; the first limiting portion 1211 can be selectively moved relative to the suspension unit 12 to install or disassemble the suspension unit 12 and the bracket 11.

[0040] Specifically, the first limiting portion 1211 can be arranged at one end of the suspension unit 12 in the first direction, and the second limiting portion 1212 can be arranged at the other end of the suspension unit 12 in the first direction. Both the first limiting portion 1211 and the second limiting portion 1212 are suitable for abutting against the bracket 11 to limit the movement of the suspension unit 12 relative to the bracket 11. The first limiting portion 1211 can move relative to the suspension unit 12. With the cooperation of the first limiting portion 1211 and the second limiting portion 1212, the suspension unit 12 can be limited to move in the assembly direction and in the disassembly direction opposite to the assembly direction. Therefore, the first limiting portion 1211 and the second limiting portion 1212 can play a good positioning role in the assembly of the suspension unit 12 and the bracket 11, and can enhance the connection strength between the suspension unit 12 and the bracket 11, and can effectively improve the assembly positioning accuracy and anti-slip performance of the suspension unit 12. When the suspension unit 12 and the bracket 11 need to be disassembled, the first limiting portion 1211 can move relative to the suspension unit 12 and release the movement restriction between the suspension unit 12 and the bracket 11 in the disassembly direction, so that the suspension unit 12 and the bracket 11 can be disassembled quickly and easily, which can improve the disassembly and maintenance efficiency and convenience of the suspension assembly 1.

[0041] like Figure 2 and Figure 3 As shown, according to some embodiments of the utility model, the first limiting portion 1211 includes: a catch 12111, an end of the catch 12111 is connected to the suspension unit 12, at least a portion of the catch 12111 is spaced apart from the periphery of the suspension unit 12, and one end of the catch 12111 moves away from or close to the axis of the suspension unit 12 to install or disassemble the suspension unit 12 and the bracket 11.

[0042] Specifically, the catch 12111 can be set on the periphery of the suspension unit 12, the two ends of the catch 12111 in the extension direction can be connected to the suspension unit 12, and the middle part of the catch 12111 can be spaced apart from the periphery of the suspension unit 12 to provide the required moving space for the catch 12111 to move relative to the suspension unit 12. One end of the catch 12111 can be moved away from or close to the axis of the suspension unit 12 to install or remove the suspension unit 12 from the bracket 11. For example, when the suspension unit 12 moves to a preset assembly position along a first direction, one end of the catch 12111 can be moved in a direction away from the axis of the suspension unit 12 to limit the movement of the suspension unit 12 relative to the bracket 11 in the first direction, thereby achieving installation and fixation between the suspension unit 12 and the bracket 11. When the suspension unit 12 and the bracket 11 need to be removed, one end of the catch 12111 can be moved in a direction close to the axis of the suspension unit 12 to release the movement restriction between the suspension unit 12 and the bracket 11 in the first direction, so that the suspension unit 12 can be removed.

[0043] like Figure 2 As shown, according to some embodiments of the present invention, the buckle 12111 includes: a first section 121111 and a second section 121112 .

[0044] Among them, one end of the first section 121111 is connected to the suspension unit 12; one end of the second section 121112 is connected to the other end of the first section 121111, and the other end is movably connected to the suspension unit 12, the second section 121112 protrudes from the outer periphery of the first section 121111, and defines a first limiting surface 121112a suitable for abutting against one end of the bracket 11.

[0045] Specifically, one end of the first section 121111 and the other end of the second section 121112 are both connected to the suspension unit 12, and the other end of the second section 121112 can move closer to or away from the suspension unit 12, and drive the first section 121111 to move closer to or away from the suspension unit 12. When the suspension unit 12 moves along the first direction to a preset assembly position, the second section 121112 and the first section 121111 can move away from the suspension unit 12. The second section 121112 protrudes from the outer periphery of the first section 121111, and the second section 121112 and the side of the first section 121111 facing away from the suspension unit 12 can define a first limiting surface 121112a. The first limiting surface 121112a is used to abut against one end of the bracket 11 to limit the movement of the suspension unit 12 relative to the bracket 11 in a first direction, thereby preventing the suspension unit 12 from escaping from the mounting hole 11a, and effectively improving the assembly reliability of the suspension unit 12 and the bracket 11.

[0046] It should be pointed out that, in the process of assembling the suspension unit 12 to the mounting hole 11a along the first direction, at least part of the outer peripheral surface of the second section 121112 can contact the inner wall of the mounting hole 11a, and generate a force on the inner wall of the mounting hole 11a. Under the reaction force of the inner wall of the mounting hole 11a, the second section 121112 can move close to the suspension unit 12, and drive the first section 121111 to move close to the suspension unit 12, so that the suspension unit 12 enters the mounting hole 11a; after the suspension unit 12 moves to the preset assembly position along the first direction, the second section 121112 can move away from the suspension unit 12, so that the first limiting surface 121112a abuts against the bracket 11.

[0047] In addition, in some specific embodiments of the present invention, the second section 121112 is constructed as an arc-shaped section protruding away from the axis of the suspension unit 12. This is beneficial for the second section 121112 to easily move toward the direction close to the axis of the suspension unit 12 after being subjected to the reaction force of the inner wall of the mounting hole 11a, thereby helping to improve the smoothness of the installation of the suspension unit 12.

[0048] like Figure 2 and Figure 3 As shown, according to some embodiments of the present invention, a guide slope 121111a is formed on the side of the first section 121111 radially away from the suspension unit 12, and at least a portion of the inner wall of the mounting hole 11a is inclined and defines a mating surface suitable for fitting with the guide slope 121111a in the installation position.

[0049] Specifically, a guiding inclined surface 121111a may be formed on the first section 121111, and at least a portion of the inner wall of the mounting hole 11a may be configured as an inclined mating surface. During the assembly process of the suspension unit 12 and the bracket 11, the guiding inclined surface 121111a and the mating surface may be matched to play a good positioning and guiding role in the installation of the suspension unit 12, which is conducive to improving the installation convenience and efficiency of the suspension unit 12. When the suspension unit 12 moves to a preset assembly position along the first direction, the guiding inclined surface 121111a may fit with the mating surface, which may further improve the connection stability between the suspension unit 12 and the bracket 11.

[0050] like Figure 2 and Figure 3 As shown, according to some embodiments of the present invention, the catch 12111 is constructed as a plastic part.

[0051] Specifically, the catch 12111 can be constructed as a plastic part. For example, the catch 12111 can be constructed as a nylon material. In this way, the catch 12111 itself can have good ductility. During the installation and disassembly of the suspension unit 12 and the bracket 11, the catch 12111 needs to move relative to the suspension unit 12. By constructing the catch 12111 as a plastic part, it can be ensured that the catch 12111 has good tensile and bending capabilities, which is beneficial to extend the service life of the catch 12111 and improve the working reliability of the catch 12111.

[0052] like Figure 2 and Figure 3 As shown, according to some embodiments of the present invention, the first limiting portion 1211 further includes: an elastic member 12112 , one end of the elastic member 12112 is connected to one end of the catch 12111 , and the other end is connected to the suspension unit 12 .

[0053] Specifically, the elastic member 12112 can be arranged between the suspension unit 12 and the catch 12111. When the suspension unit 12 is assembled to the mounting hole 11a along the first direction, the catch 12111 can contact the inner wall of the mounting hole 11a. Under the pressure of the inner wall of the mounting hole 11a, the catch 12111 moves toward the direction close to the axis of the suspension unit 12 and compresses the elastic member 12112. When the suspension unit 12 moves to the preset assembly position along the first direction, the restoring force of the elastic member 12112 can drive the catch 12111 to move in the direction away from the axis of the suspension unit 12, so that the first limiting surface 121112a of the catch 12111 can abut against the bracket 11, thereby limiting the movement of the suspension unit 12 relative to the bracket 11. Therefore, by providing the elastic member 12112, the catch 12111 can move relative to the suspension unit 12 during the assembly process of the suspension unit 12 and after being assembled to the preset position, thereby ensuring the normal assembly of the suspension unit 12 and ensuring that the catch 12111 plays a good limiting role on the suspension unit 12.

[0054] It should be pointed out that when the suspension unit 12 needs to be disassembled, the catch 12111 can be pushed with suitable tooling to compress the elastic member 12112, thereby releasing the limit and enabling the suspension unit 12 to be quickly disassembled, thereby effectively improving the convenience and efficiency of disassembly and maintenance of the suspension unit 12.

[0055] In addition, in some specific embodiments of the present invention, the elastic member 12112 is constructed as a spring. Since the spring has the advantages of large elasticity, good durability and low cost, constructing the elastic member 12112 as a spring helps to optimize the working performance and service life of the elastic member 12112 and save economic costs.

[0056] like Figure 2As shown, according to some embodiments of the present invention, the second limiting portion 1212 protrudes from the outer periphery of the suspension unit 12 and defines a second limiting surface 1212 a suitable for abutting against the other end of the bracket 11 .

[0057] Specifically, the second limiting portion 1212 can protrude from the outer periphery of the suspension unit 12 and define a first limiting surface 121112a. When the suspension unit 12 is assembled to a preset position along the first direction, the second limiting surface 1212a can abut against the other end of the bracket 11 to limit the suspension unit 12 from continuing to move in the assembly direction, so that the second limiting surface 1212a can play a good positioning and limiting role in the assembly between the suspension unit 12 and the bracket 11. Among them, the second limiting surface 1212a and the first limiting surface 121112a on the first limiting portion 1211 can be opposite to each other in the first direction, and the first limiting surface 121112a can abut against one end of the bracket 11 to prevent the suspension unit 12 from escaping from the mounting hole 11a. Therefore, after the suspension unit 12 moves to the preset assembly position, the second limiting surface 1212a and the first limiting surface 121112a can play a bidirectional (assembly direction and disassembly direction opposite to the assembly direction) limiting role on the suspension unit 12. In this way, the assembly firmness and stability between the suspension unit 12 and the bracket 11 can be effectively improved, and the working performance and reliability of the suspension component 1 can be improved.

[0058] like Figure 1 and Figure 3 As shown, according to some embodiments of the present invention, a connecting portion 111 is formed on a side of the bracket 11 away from the mounting hole 11 a in the thickness direction, and the connecting portion 111 is suitable for connecting to a vehicle body and a powertrain.

[0059] Specifically, a connecting portion 111 may be formed on the bracket 11, and the connecting portion 111 may extend away from the bracket 11 in a direction away from the mounting hole 11a. The connecting portion 111 may be connected to the vehicle body and the powertrain (such as an engine) to achieve a fixed connection between the suspension assembly 1 and the vehicle body and the powertrain. Exemplarily, the connecting portion 111 may be fixedly connected to the vehicle body and the powertrain by a fastener to facilitate installation and disassembly.

[0060] In addition, in some specific embodiments of the present invention, the projection of the connecting portion 111 in the extension direction of the mounting hole 11a is spaced from the projection of the second limiting portion 1212 in the extension direction of the mounting hole 11a. In this way, it can be ensured that the second limiting portion 1212 will not interfere with the connecting portion 111 when moving, thereby improving the working reliability and life of the second limiting portion 1212.

[0061] like Figure 1-Figure 3As shown, according to the vehicle of the second embodiment of the utility model, the vehicle includes: the suspension assembly 1 described in any one of the above embodiments, and the technical effects produced are consistent with those in the above embodiments, which will not be repeated here.
