Description

Technical Field

[0001] The present application belongs to the field of vehicle technology, and more specifically, relates to a suspension structure and a vehicle. Background Art

[0002] In related technologies, a suspension structure generally includes a bracket and a swing arm, which are rotatably connected so that the swing arm can swing relative to the bracket structure to a certain extent during vehicle operation, thereby absorbing impact or vibration applied from the ground to the vehicle body.

[0003] In some cases, the yaw stiffness at the connection point between the bracket and the swing arm is small, affecting the handling performance and riding comfort of the wheel. Utility Model Content

[0004] In view of the above problems, embodiments of the present application provide a suspension structure and a vehicle, which can improve the yaw stiffness between the swing arm and the bracket.

[0005] In a first aspect, an embodiment of the present application provides a suspension structure, comprising:

[0006] The support structure includes a support body and a plurality of first connection structures connected to the support body at intervals;

[0007] The swing arm structure includes a swing arm body and a second connecting structure connected to the swing arm body, wherein the second connecting structure is provided between two adjacent first connecting structures;

[0008] The fastener is provided through the second connection structure and the two adjacent first connection structures so as to enable the bracket body and the swing arm body to be rotatably connected.

[0009] The suspension structure provided in the embodiment of the present application includes multiple first connection structures through the support structure, and the second connection structure of the swing arm structure is arranged between two adjacent first connection structures, and the fastener is passed through the second connection structure and the two adjacent first connection structures, so that under the action of the fastener, the second connection structure and the two adjacent first connection structures are connected to realize the rotational connection between the support body and the swing arm body. This can improve the connection stiffness between the first connection structure and the second connection structure, thereby improving the yaw stiffness between the support structure and the swing arm structure, so as to improve the vehicle's handling performance and use comfort.

[0010] In some embodiments, at least one first connection structure includes a first connection seat and a first rotating member; the first connection seat is connected to the bracket body, and a first mounting hole is provided along the axial direction of the fastener; at least a portion of the first rotating member is rotatably disposed in the first mounting hole, and the fastener is passed through the first rotating member.

[0011] The fastener is passed through the first rotating member to connect the fastener and the first rotating member. In this way, the fastener and the first rotating member can rotate together about the central axis of the fastener, so that the swing arm body can swing relative to the bracket body along with the fastener to absorb impact or vibration applied to the vehicle body from the ground.

[0012] In some embodiments, the first rotating member includes a first ball head portion, at least a portion of the first ball head portion is rotatably disposed in the first mounting hole, and the fastener is passed through the first ball head portion.

[0013] The first rotating member includes a first ball head, and at least a portion of the first ball head is rotatably disposed within the first mounting hole. This facilitates rotation of the first rotating member relative to the first connecting seat to absorb impact or vibration applied to the wheel from the ground. Furthermore, the provision of the first ball head provides the first rotating member with greater rigidity, thereby improving the connection rigidity between the first rotating member and the first connecting seat, thereby improving the yaw stiffness between the first rotating member and the first connecting seat, and thus improving the yaw stiffness between the bracket structure and the swing arm structure.

[0014] In some embodiments, the first rotating member further includes a first pin shaft portion, the first pin shaft portion and the first ball head portion are axially connected, and the fastener is passed through the first pin shaft portion.

[0015] By setting the first ball head portion and the first pin shaft portion, the structural stiffness of the first rotating member can be improved, which helps to improve the connection stiffness between the first rotating member and the first connecting seat, so as to help improve the yaw stiffness between the first rotating member and the first connecting seat, thereby improving the yaw stiffness between the bracket structure and the swing arm structure.

[0016] In some embodiments, along the axial direction, opposite ends of the first ball head are both connected to the first pin shaft portions.

[0017] Such an arrangement can improve the balancing performance of the first rotating member to improve the stability of the relative rotation between the support structure and the swing arm structure. This also helps to improve the yaw stiffness between the first rotating member and the first connecting seat, thereby improving the yaw stiffness between the support structure and the swing arm structure.

[0018] In some embodiments, the first mounting hole includes a first through hole section and a first groove section, the first through hole section axially passes through the first connecting seat, and the first groove section is connected to the outer periphery of the first through hole section; a portion of the first ball head is arranged in the first through hole section, and the other portion is axially limited in the first groove section.

[0019] By axially restraining the other portion of the first ball head within the first groove, the first rotating member can be securely restrained axially on the first connecting seat, thereby achieving a stable connection between the first rotating member and the first connecting seat. This helps to improve the connection rigidity between the first rotating member and the first connecting seat, thereby improving the yaw stiffness between the bracket structure and the swing arm structure.

[0020] In some embodiments, at least one first connection structure further includes a first filling member filled between the first connection seat and the first rotating member.

[0021] By disposing the first filling piece, the first connection structure can effectively alleviate the impact or vibration transmitted from the ground to the vehicle body.

[0022] In some embodiments, at least one first connection structure further includes a first sleeve, at least a portion of which is assembled in the first mounting hole, the first sleeve is sleeved on the outer periphery of the first rotating member, and the first filling member is filled between the first rotating member and the first sleeve.

[0023] By adopting the above technical solution, the first sleeve, the first filler, and the first rotating member can roughly form a bushing. This allows the first rotating member to rotate relative to the first sleeve, thereby achieving rotation of the swing arm body relative to the bracket body, thereby absorbing impact or vibration applied to the vehicle body from the ground. Furthermore, the first filler is inserted between the first sleeve and the first rotating member, allowing the bushing formed by the first sleeve, the first filler, and the first rotating member to be firmly assembled. This provides the bushing with a certain structural rigidity, thereby providing a certain yaw stiffness between the swing arm structure and the bracket structure.

[0024] In some embodiments, the first rotating member and the first sleeve are made of steel, aluminum or nylon.

[0025] Such a configuration enables the first rotating member and the first sleeve to have greater structural rigidity, thereby improving the connection rigidity between the first rotating member and the first connecting seat, which helps to improve the yaw rigidity between the first rotating member and the first connecting seat, thereby improving the yaw rigidity between the bracket structure and the swing arm structure.

[0026] In some embodiments, the first connecting seat and the bracket body are an integral connection structure.

[0027] Such an arrangement can improve the connection strength between the first connecting seat and the bracket body, thereby improving the structural rigidity of the bracket structure, thereby also helping to improve the yaw rigidity between the swing arm structure and the bracket structure.

[0028] In some embodiments, the second connecting structure includes a second connecting seat and a second rotating member; the second connecting seat is connected to the swing arm body, and a second mounting hole is provided along the axial direction of the fastener; at least a portion of the second rotating member is rotatably disposed in the second mounting hole, and the fastener is passed through the second rotating member.

[0029] The fastener is passed through the second rotating member to connect the fastener to the second rotating member. Thus, the fastener and the second rotating member can rotate together about the central axis of the fastener, allowing the swing arm body to rotate relative to the fastener and thus swing relative to the bracket body to absorb impact or vibration applied to the wheel from the ground.

[0030] In some embodiments, the second rotating member includes a second ball head portion and a second pin shaft portion, and the second pin shaft portion and the second ball head portion are axially connected; at least a portion of the second ball head portion is rotatably disposed in the second mounting hole, and the fastener is passed through the second ball head portion and the second pin shaft portion.

[0031] The second rotating member includes a second ball head, and at least a portion of the second ball head is rotatably disposed within the second mounting hole. This facilitates rotation of the second rotating member relative to the second connecting seat to absorb impact or vibration applied to the wheel from the ground. Furthermore, the arrangement of the second ball head and the second pin portion imparts greater rigidity to the second rotating member, thereby increasing the connection rigidity between the second rotating member and the connecting seat, thereby increasing the yaw stiffness between the second rotating member and the connecting seat, and thus increasing the yaw stiffness between the bracket structure and the swing arm structure.

[0032] In some embodiments, along the axial direction, opposite ends of the second ball head are connected to second pin shaft portions.

[0033] Such an arrangement can improve the balancing performance of the second rotating member to improve the stability of the relative rotation between the support structure and the swing arm structure. This also helps to improve the yaw stiffness between the second rotating member and the second connecting seat, thereby improving the yaw stiffness between the support structure and the swing arm structure.

[0034] In some embodiments, the second mounting hole includes a second through hole section and a second groove section, the second through hole section axially passes through the second connecting seat, and the second groove section is connected to the outer periphery of the second through hole section; a portion of the second ball head portion and at least a portion of the second pin shaft portion are arranged in the second through hole section, and the other portion of the second ball head portion is axially limited in the second groove section.

[0035] By axially restraining the other portion of the second ball head within the second groove segment, the second rotating member can be securely restrained axially on the second connecting seat, thereby achieving a stable connection between the second rotating member and the second connecting seat. This helps to improve the connection rigidity between the second rotating member and the second connecting seat, thereby improving the yaw stiffness between the bracket structure and the swing arm structure.

[0036] In some embodiments, the second connection structure further comprises:

[0037] a second sleeve, at least partially assembled in the second mounting hole, and sleeved on the outer periphery of the second rotating member;

[0038] The second filling member is filled between the second sleeve and the second rotating member.

[0039] By adopting the above technical solution, the second sleeve, the second filler, and the second rotating member can roughly form a bushing. This allows the second rotating member to rotate relative to the second sleeve, thereby achieving rotation of the swing arm body relative to the bracket body, thereby absorbing impact or vibration applied to the vehicle body from the ground. Furthermore, the second filler is inserted between the second sleeve and the second rotating member, ensuring a stable assembly of the bushing formed by the second sleeve, the second filler, and the second rotating member. This provides a certain structural rigidity to the bushing, thereby providing a certain yaw stiffness between the swing arm structure and the bracket structure.

[0040] In some embodiments, along the axial direction of the fastener, the second connecting structure abuts between two adjacent first connecting structures.

[0041] Such an arrangement enables the first connecting structure and the second connecting structure to abut against each other axially, which helps to improve the connection stiffness between the first connecting structure and the second connecting structure, thereby improving the yaw stiffness between the first connecting structure and the second connecting structure, thereby improving the yaw stiffness between the swing arm body and the bracket body.

[0042] In some embodiments, the swing arm structure includes a plurality of second connection structures connected to the swing arm body at intervals, and the first connection structure is arranged between two adjacent second connection structures.

[0043] Such an arrangement allows the first connecting structure to be limited axially between two adjacent second connecting structures, and the second connecting structure to be limited axially between two adjacent first connecting structures, which can greatly improve the connection stiffness between the first connecting structure and the second connecting structure, thereby improving the yaw stiffness between the first connecting structure and the second connecting structure, thereby improving the yaw stiffness between the swing arm body and the bracket body.

[0044] In some embodiments, a third mounting hole is formed through the bracket body along the axial direction of the fastener, and the third mounting hole is used to connect to the wheel.

[0045] This arrangement allows the swing arm body's rotational axis relative to the support body to be substantially parallel to the wheel axle. Thus, the suspension structure provided by the embodiments of the present application, while allowing the swing arm body to rotate relative to the support body about a central axis parallel to the wheel axle, can improve the yaw stiffness between the swing arm body and the support body.

[0046] In some embodiments, the swing arm body includes a rear swing arm or a torsion beam rear axle swing arm.

[0047] Such an arrangement can improve the yaw stiffness between the rear swing arm and the bracket body; or, can improve the yaw stiffness between the torsion beam rear axle swing arm and the bracket body.

[0048] In a second aspect, an embodiment of the present application provides a vehicle comprising a suspension structure.

[0049] The vehicle provided in the embodiments of the present application, by adopting the suspension structure involved in the above embodiments, can improve the yaw stiffness between the support structure and the swing arm structure, thereby improving the vehicle's handling performance and usage comfort.

In the axial direction X, the second connection structure 22 is provided between two adjacent first connection structures 12, so that the second connection structure 22 is located between the two adjacent first connection structures 12 along the axial direction X. Based on this, the first connection structures 12 and the second connection structures 22 are distributed along the axial direction X.

[0104] The fastener 30 is provided through the second connecting structure 22 and the two adjacent first connecting structures 12, meaning that the fastener 30 is provided through at least the second connecting structure 22 and the two adjacent first connecting structures 12.

Figure 5 A partial cross-sectional view of a suspension structure 400 provided in some other embodiments of the present application is shown. Figure 6 for Figure 5Enlarged view of point C in the middle. The at least one first connecting structure 12 includes a first connecting base 121 and a first rotating member 122. The first connecting base 121 is connected to the bracket body 11 and has a first mounting hole 101 extending therethrough along the axial direction X of the fastener 30. At least a portion of the first rotating member 122 is rotatably disposed within the first mounting hole 101, and the fastener 30 is disposed through the first rotating member 122.

[0109] The first connecting seat 121 is a component on the first connecting structure 12 used for connecting to the bracket body 11 .

[0110] The first mounting hole 101 is a through hole that passes through the first connecting seat 121 along the axial direction X of the fastener 30 . The first mounting hole 101 is used for mounting the first rotating member 122 .

[0111] The first rotating member 122 is a component that can rotate relative to the first connecting seat 121. At least a portion of the first rotating member 122 is disposed in the first mounting hole 101, and the first rotating member 122 can rotate relative to the first mounting hole 101 around the central axis L of the fastener 30.

[0112] The fastener 30 is disposed in the first rotating member 122 . Specifically, the fastener 30 is disposed in the first rotating member 122 along the axial direction X and is fixedly connected to the first rotating member 122 , thereby enabling the fastener 30 to be disposed in the first connecting structure 12 along the axial direction X.

[0113] The fastener 30 is passed through the first rotating member 122, thereby connecting the fastener 30 to the first rotating member 122. Thus, the fastener 30 and the first rotating member 122 can rotate together about the central axis L of the fastener 30, so that the swing arm body 21 can swing relative to the bracket body 11 along with the fastener 30 to absorb impact or vibration applied to the vehicle body from the ground.

[0114] In some embodiments, as Figures 2 to 6 As shown, two adjacent first connection structures 12 each include the first connection seat 121 and the first rotating member 122 .

[0115] In some other embodiments, at least one first connection structure 12 may include a first connection seat 121 but not a first rotating member 122, and the fastener 30 is passed through the first mounting hole 101 to be connected to the first connection seat 121, such as Figures 7 to 10 For example, among two adjacent first connection structures 12 , one of the first connection structures 12 includes a first connection base 121 and a first rotating member 122 , while the other first connection structure 12 includes the first connection base 121 but does not include the first rotating member 122 .

[0116] In some embodiments, please refer to Figures 2 to 6The first rotating member 122 includes a first ball head 1221 . At least a portion of the first ball head 1221 is rotatably disposed in the first mounting hole 101 . The fastener 30 is disposed through the first ball head 1221 .

[0117] The first ball head 1221 is at least a portion of the first rotating member 122 , and the first ball head 1221 is substantially in the shape of a ball head.

[0118] At least a portion of the first ball head 1221 is disposed in the first mounting hole 101 , and the first ball head 1221 is capable of rotating relative to the first mounting hole 101 around the central axis L of the fastener 30 .

[0119] The fastener 30 is passed through the first ball head 1221 along the axial direction X, so that the fastener 30 and the first ball head 1221 are fixedly connected.

[0120] Because the first rotating member 122 includes a first ball head 1221, and at least a portion of the first ball head 1221 is rotatably disposed within the first mounting hole 101, the first rotating member 122 can rotate relative to the first connecting seat 121 to absorb impact or vibration applied to the wheel from the ground. Furthermore, the provision of the first ball head 1221 provides the first rotating member 122 with greater rigidity, thereby improving the connection rigidity between the first rotating member 122 and the first connecting seat 121, thereby improving the yaw stiffness between the first rotating member 122 and the first connecting seat 121, and thus improving the yaw stiffness between the support structure 10 and the swing arm structure 20.

[0121] In some embodiments, please refer to Figures 2 to 6 The first rotating member 122 further includes a first pin portion 1222 , the first pin portion 1222 and the first ball head portion 1221 are connected along the axial direction X, and the fastener 30 is disposed through the first pin portion 1222 .

[0122] The first pin shaft portion 1222 is a partial structure of the first rotating member 122. The first pin shaft portion 1222 is substantially in the shape of a shaft.

[0123] The first pin portion 1222 and the first ball head portion 1221 are distributed and connected along the axial direction X. The fastener 30 is provided through the first pin portion 1222 and the first ball head portion 1221 along the axial direction X, so that the fastener 30 is fixedly connected to the first ball head portion 1221 and the first pin portion 1222 respectively, thereby achieving the fastener 30 being provided through the first rotating member 122 along the axial direction X.

[0124] Since the first rotating member 122 includes the first ball head portion 1221 and the first pin shaft portion 1222 , it can be understood that the first rotating member 122 is substantially a ball pin.

[0125] By setting the first ball head portion 1221 and the first pin shaft portion 1222, the structural stiffness of the first rotating member 122 can be improved, which helps to improve the connection stiffness between the first rotating member 122 and the first connecting seat 121, so as to help improve the yaw stiffness between the first rotating member 122 and the first connecting seat 121, thereby improving the yaw stiffness between the bracket structure 10 and the swing arm structure 20.

[0126] It should be supplemented here that the first pin can be located on the first connecting seat 121 along the radial direction Y of the fastener 30 , which helps to improve the connection stiffness between the first connecting structure 12 and the second connecting structure 22 .

[0127] Herein, unless otherwise specified below, the radial direction Y of the fastener 30 may be referred to as radial direction Y.

[0128] In some embodiments, at least a portion of the first pin may be located outside the first mounting hole 101 .

[0129] In some embodiments, please refer to Figures 2 to 6 Along the axial direction X of the fastener 30 , opposite ends of the first ball head 1221 are connected to the first pin shaft 1222 .

[0130] Such a setting can improve the balancing performance of the first rotating member 122 to improve the stability of the relative rotation between the support structure 10 and the swing arm structure 20. This also helps to improve the yaw stiffness between the first rotating member 122 and the first connecting seat 121, thereby improving the yaw stiffness between the support structure 10 and the swing arm structure 20.

[0131] In some embodiments, please refer to Figures 2 to 4 , and in conjunction with other figures. The first mounting hole 101 includes a first through-hole section 1011 and a first groove section 1012. The first through-hole section 1011 extends through the first connecting seat 121 along the axial direction X, and the first groove section 1012 is connected to the outer periphery of the first through-hole section 1011. A portion of the first ball head 1221 is disposed within the first through-hole section 1011, and the other portion is confined within the first groove section 1012 along the axial direction X.

[0132] The first through hole section 1011 and the first groove section 1012 are two parts of the first mounting hole 101. The first groove section 1012 is arranged around the outer periphery of the first through hole section 1011, and the first groove section 1012 and the first through hole section 1011 are in communication.

[0133] Specifically, the first ball head 1221 and the first groove section 1012 are matched in a concave-convex manner along the radial direction Y of the fastener 30, so that the other part of the first ball head 1221 is located in the first groove section 1012 along the axial direction X.

[0134] By constraining the other portion of the first ball head 1221 within the first groove section 1012 along the axial direction X, the first rotating member 122 can be firmly constrained on the first connecting seat 121 along the axial direction X, thereby achieving a secure connection between the first rotating member 122 and the first connecting seat 121. This helps to improve the connection rigidity between the first rotating member 122 and the first connecting seat 121, thereby improving the yaw rigidity between the support structure 10 and the swing arm structure 20.

[0135] Specifically, at least a portion of the first pin shaft portion 1222 is disposed in the first through hole section 1011 .

[0136] In some embodiments, as Figures 2 to 4 As shown, the inner peripheral wall of the first groove section 1012 matches the outer peripheral wall of the first ball head 1221, so as to improve the connection stiffness between the first rotating member 122 and the first connecting seat 121, so as to improve the connection stiffness between the first connecting structure 12 and the second connecting structure 22, thereby improving the yaw stiffness between the bracket structure 10 and the swing arm structure 20.

[0137] In some embodiments, the first connecting seat 121 may include a first seat body, a first stopper, and a second stopper. The first seat body has a first mounting hole 101 formed therethrough along the axial direction X. The first stopper and the second stopper are spaced apart on the first seat body along the axial direction X. Furthermore, in the axial direction X, the portion of the first mounting hole 101 between the first stopper and the second stopper forms a first groove section 1012. That is, the inner circumferential wall of the first seat body, the first stopper, and the second stopper form the first groove section 1012. At least a portion of the first ball head 1221 is confined between the first stopper and the second stopper along the axial direction X.

[0138] In some embodiments, at least one of the first and second stoppers is detachably connected to the first base. With this arrangement, after at least a portion of the first ball head 1221 is installed in the first mounting hole 101, the first and second stoppers can be connected to the first base, thereby facilitating the installation of the first rotating member 122 on the first connecting base 121.

[0139] In other embodiments, a first connecting hole may be provided through the inner circumferential wall of the first mounting hole 101, and the first connecting hole extends through the first connecting seat 121 along the axial direction X. Based on the configuration of the first connecting hole, the first connecting hole may be first opened by an external force to allow at least a portion of the first ball head 1221 to be installed within the first mounting hole 101. Then, fasteners may be inserted through the opposing side walls of the first connecting hole to reduce the size of the first connecting hole and the first mounting hole 101, thereby allowing the first ball head 1221 to be securely mounted to the first connecting seat 121.

[0140] In some embodiments, please refer to Figure 5and Figure 6 The first connection structure 12 further includes a first filling member 124 , which is filled between the first connection seat 121 and the first rotating member 122 .

[0141] The first filling member 124 refers to a filling material filled between the first connecting seat 121 and the first rotating member 122. The first filling member 124 can be, but is not limited to, a rubber layer.

[0142] As an example, the first filling member 124 may be filled between the inner peripheral wall of the first mounting hole 101 and the outer peripheral wall of the first rotating member 122. Based on this, the first rotating member 122, the first filling member 124 and the first connecting seat 121 may substantially constitute a bushing.

[0143] By disposing the first filling piece 124 , the first connecting structure 12 can effectively alleviate the impact or vibration transmitted from the ground to the vehicle body.

[0144] It should be noted that when the first mounting hole 101 includes a first through hole section 1011 and a first groove section 1012 , a first filling piece 124 can be provided in the first mounting hole 101 to divide the first mounting hole 101 into the first through hole section 1011 and the first groove section 1012 .

[0145] In some embodiments, please refer to Figure 5 and Figure 6 The first connecting structure 12 further includes a first sleeve 123 , at least a portion of which is assembled within the first mounting hole 101 . The first sleeve 123 is sleeved around the outer periphery of the first rotating member 122 , and a first filling member 124 is filled between the first rotating member 122 and the first sleeve 123 .

[0146] The first sleeve 123 is a component for mounting the first rotating member 122 and the first filling member 124 , and is substantially in the shape of a sleeve.

[0147] The first connecting seat 121 is sleeved on the outer periphery of the first sleeve 123 .

[0148] The first filling member 124 is filled between the outer circumferential wall of the first rotating member 122 and the inner circumferential wall of the first sleeve 123. The first filling member 124 can be filled between the outer circumferential wall of the first ball head 1221 and the inner circumferential wall of the first sleeve 123, or between the outer circumferential wall of the first pin shaft 1222 and the inner circumferential wall of the first sleeve 123.

[0149] By employing the above-described technical solution, the first sleeve 123, the first filler 124, and the first rotating member 122 can roughly form a bushing. This allows the first rotating member 122 to rotate relative to the first sleeve 123, thereby enabling the swing arm body 21 to rotate relative to the support body 11, thereby absorbing impact or vibration applied to the vehicle body from the ground. Furthermore, the first filler 124 is inserted between the first sleeve 123 and the first rotating member 122, ensuring a stable assembly of the bushing formed by the first sleeve 123, the first filler 124, and the first rotating member 122. This provides a certain degree of structural rigidity to the bushing, thereby providing a certain degree of yaw stiffness between the swing arm structure 20 and the support structure 10.

[0150] It should be noted here that when the first mounting hole 101 includes a first through hole section 1011 and a first groove section 1012, a first filling piece 124 and a first sleeve 123 can be arranged in the first mounting hole 101 to divide the first mounting hole 101 into the above-mentioned first through hole section 1011 and first groove section 1012.

[0151] In some embodiments, as Figures 2 to 6 As shown, two adjacent first connection structures 12 may include the above-mentioned first connection seat 121 and the above-mentioned first rotating member 122, but not the above-mentioned first filling member 124 and the first sleeve 123, and the first rotating member 122 includes the above-mentioned first ball head 1221 and the first pin shaft portion 1222.

[0152] In some other embodiments, of two adjacent first connecting structures 12, one of the first connecting structures 12 includes the first connecting seat 121 and the first rotating member 122, but does not include the first filling member 124 and the first sleeve 123, and the first rotating member 122 includes the first ball head 1221 and the first pin shaft 1222. The other first connecting structure 12 includes the first connecting seat 121, the first rotating member 122, the first sleeve 123, and the first filling member 124.

[0153] In some embodiments, the first sleeve 123 is interference-fitted with the first mounting hole 101. This arrangement allows the bushing formed by the first sleeve 123, the first filler 124, and the first rotating member 122 to be securely assembled with the first connecting seat 121, thereby helping to improve the yaw stiffness between the swing arm structure 20 and the bracket structure 10.

[0154] In some embodiments, please refer to Figures 2 to 6 , and in conjunction with other figures, the first rotating member 122 is a steel structure, an aluminum structure, or a nylon structure. In addition, the first sleeve 123 is a steel structure, an aluminum structure, or a nylon structure.

[0155] Such a configuration enables the first rotating member 122 and the first sleeve 123 to have greater structural rigidity, thereby improving the connection rigidity between the first rotating member 122 and the first connecting seat 121, which helps to improve the yaw rigidity between the first rotating member 122 and the first connecting seat 121, thereby improving the yaw rigidity between the support structure 10 and the swing arm structure 20.

[0156] In some embodiments, please refer to Figures 2 to 6 , and in combination with other drawings. The first connecting seat 121 and the bracket body 11 are an integral connection structure.

[0157] As an example, the first connecting seat 121 and the bracket body 11 are both metal structures, and the first connecting seat 121 and the bracket body 11 can be integrally formed by stamping, die-casting, pouring, etc.

[0158] Such an arrangement can improve the connection strength between the first connecting seat 121 and the bracket body 11 to improve the structural rigidity of the bracket structure 10 , thereby also helping to improve the yaw rigidity between the swing arm structure 20 and the bracket structure 10 .

[0159] In some other embodiments, the first connecting seat 121 and the bracket body 11 may also be connected by welding, bolting, riveting, or the like.

[0160] In some embodiments, please refer to Figures 7 to 11 , and combined with other drawings. Among them, Figure 7 This is a partial three-dimensional structural diagram of a suspension structure 400 provided in some embodiments of the present application. Figure 8 for Figure 7 Cross-sectional view along DD, Figure 9 for Figure 8 Enlarged view of point E in the middle. Figure 10 A partial cross-sectional view of a suspension structure 400 provided in some further embodiments of the present application is shown. Figure 11 for Figure 10 Enlarged view of point F in the middle. The second connecting structure 22 includes a second connecting base 221 and a second rotating member 222. The second connecting base 221 is connected to the swing arm body 21 and has a second mounting hole 201 extending therethrough along the axial direction X of the fastener 30. At least a portion of the second rotating member 222 is rotatably disposed within the second mounting hole 201, and the fastener 30 is disposed through the second rotating member 222.

[0161] The second connecting seat 221 is a component on the second connecting structure 22 used for connecting to the swing arm body 21 .

[0162] The second mounting hole 201 is a through hole that passes through the second connecting seat 221 along the axial direction X of the fastener 30 . The second mounting hole 201 is used for mounting the second rotating member 222 .

[0163] The second rotating member 222 is a component that can rotate relative to the second connecting seat 221. At least a portion of the second rotating member 222 is disposed in the second mounting hole 201, and the second rotating member 222 can rotate relative to the second mounting hole 201 around the central axis L of the fastener 30.

[0164] The fastener 30 is passed through the second rotating member 222 , specifically, the fastener 30 is passed through the second rotating member 222 along the axial direction X, so that the fastener 30 and the second rotating member 222 are fixedly connected, thereby realizing that the fastener 30 is passed through the second connecting structure 22 along the axial direction X.

[0165] The fastener 30 passes through the second rotating member 222, thereby connecting the fastener 30 to the second rotating member 222. Thus, the fastener 30 can rotate together with the second rotating member 222 around the central axis L of the fastener 30, so that the swing arm body 21 can rotate relative to the fastener 30, thereby swinging relative to the bracket body 11 to absorb impact or vibration applied to the wheel from the ground.

[0166] In some embodiments, as Figures 2 to 6 As shown, the second connection structure 22 may include the second connection seat 221 but not the second rotating member 222 .

[0167] In some embodiments, please refer to Figures 7 to 11 , and in conjunction with other drawings. The second rotating member 222 includes a second ball head 2221 and a second pin portion 2222. The second pin portion 2222 and the second ball head 2221 are connected along the axial direction X. At least a portion of the second ball head 2221 is rotatably disposed within the second mounting hole 201. The fastener 30 is disposed through the second ball head 2221 and the second pin portion 2222.

[0168] The second ball head portion 2221 and the second pin shaft portion 2222 are two parts of the second rotating member 222. The second ball head portion 2221 is substantially in the shape of a ball head, and the second pin shaft portion 2222 is substantially in the shape of a shaft.

[0169] At least a portion of the second ball head 2221 is disposed in the second mounting hole 201 , and the second ball head 2221 is capable of rotating relative to the second mounting hole 201 around the central axis L of the fastener 30 .

[0170] Since the second rotating member 222 includes the second ball head portion 2221 and the second pin shaft portion 2222 , the second rotating member 222 is substantially a ball pin.

[0171] The second pin portion 2222 and the second ball head portion 2221 are distributed and connected along the axial direction X. The fastener 30 is provided through the second pin portion 2222 and the second ball head portion 2221 along the axial direction X, so that the fastener 30 is fixedly connected to the second pin portion 2222 and the second ball head portion 2221 respectively. The fastener 30 is provided through the second rotating member 222 along the axial direction X, thereby achieving a fixed connection between the fastener 30 and the second rotating member 222.

[0172] Because the second rotating member 222 includes a second ball head 2221, and at least a portion of the second ball head 2221 is rotatably disposed within the second mounting hole 201, the second rotating member 222 can rotate relative to the second connecting seat 221 to absorb impact or vibration applied to the wheel from the ground. Furthermore, the arrangement of the second ball head 2221 and the second pin shaft 2222 provides the second rotating member 222 with greater rigidity, thereby improving the connection rigidity between the second rotating member 222 and the second connecting seat 221, thereby improving the yaw stiffness between the second rotating member 222 and the second connecting seat 221, and thus improving the yaw stiffness between the support structure 10 and the swing arm structure 20.

[0173] It should be supplemented here that the second pin shaft can be located on the second connecting seat 221 along the radial direction Y of the fastener 30 , which helps to improve the connection stiffness between the first connecting structure 12 and the second connecting structure 22 .

[0174] In some embodiments, at least a portion of the second pin may be located outside the second mounting hole 201 .

[0175] In some embodiments, please refer to Figures 7 to 11 Along the axial direction X of the fastener 30 , the opposite ends of the second ball head 2221 are connected to the second pin shaft 2222 .

[0176] Such a setting can improve the balancing performance of the second rotating member 222 to improve the stability of the relative rotation between the support structure 10 and the swing arm structure 20. This also helps to improve the yaw stiffness between the second rotating member 222 and the second connecting seat 221, thereby improving the yaw stiffness between the support structure 10 and the swing arm structure 20.

[0177] In some embodiments, please refer to Figures 7 to 9, and in conjunction with other drawings. The second mounting hole 201 includes a second through-hole section 2011 and a second groove section 2012. The second through-hole section 2011 extends through the second connecting seat 221 along the axial direction X, and the second groove section 2012 communicates with the outer periphery of the second through-hole section 2011. A portion of the second ball head 2221 and at least a portion of the second pin shaft portion 2222 are disposed within the second through-hole section 2011, while the remaining portion of the second ball head 2221 is confined within the second groove section 2012 along the axial direction X.

[0178] The second through hole section 2011 and the second groove section 2012 are two parts of the second mounting hole 201. The second groove section 2012 is arranged around the outer periphery of the second through hole section 2011, and the second groove section 2012 is communicated with the second through hole section 2011.

[0179] Specifically, the second ball head 2221 and the second groove section 2012 are matched in a concave-convex manner along the radial direction Y of the fastener 30, so that another part of the second ball head 2221 is located in the second groove section 2012 along the axial direction X.

[0180] By constraining the other portion of the second ball head 2221 within the second groove section 2012 along the axial direction X, the second rotating member 222 can be firmly constrained on the second connecting seat 221 along the axial direction X, thereby achieving a secure connection between the second rotating member 222 and the second connecting seat 221. This helps to improve the connection rigidity between the second rotating member 222 and the second connecting seat 221, thereby improving the yaw rigidity between the support structure 10 and the swing arm structure 20.

[0181] In some embodiments, as Figures 7 to 9 As shown, the inner circumferential wall of the second groove section 2012 matches the outer circumferential wall of the second ball head 2221, so as to improve the connection stiffness between the second rotating member 222 and the second connecting seat 221, thereby improving the connection stiffness between the first connecting structure 12 and the second connecting structure 22, thereby improving the yaw stiffness between the bracket structure 10 and the swing arm structure 20.

[0182] In some embodiments, the second connecting seat 221 may include a second seat body, a third stopper, and a fourth stopper. The second seat body has a second mounting hole 201 formed therethrough along the axial direction X. The third stopper and the fourth stopper are spaced apart on the second seat body along the axial direction X. Furthermore, in the axial direction X, the portion of the second mounting hole 201 between the third stopper and the fourth stopper forms a second groove section 2012. That is, the inner circumferential wall of the second seat body, the third stopper, and the fourth stopper form the second groove section 2012. At least a portion of the second ball head 2221 is confined between the third stopper and the fourth stopper along the axial direction X.

[0183] In some embodiments, at least one of the third and fourth stoppers is detachably connected to the second base. With this arrangement, after at least a portion of the second ball head 2221 is installed in the second mounting hole 201, the third and fourth stoppers can be connected to the second base, thereby facilitating the installation of the second rotating member 222 on the second connecting base 221.

[0184] In other embodiments, a second connecting hole may be provided through the inner circumferential wall of the second mounting hole 201, and the second connecting hole extends through the second connecting seat 221 along the axial direction X. Based on the configuration of the second connecting hole, the second connecting hole may be first opened by an external force to allow at least a portion of the second ball head 2221 to be installed within the second mounting hole 201. Then, fasteners may be inserted through the opposing side walls of the second connecting hole to reduce the size of the second connecting hole and the second mounting hole 201, thereby allowing the second ball head 2221 to be securely mounted on the second connecting seat 221.

[0185] In some embodiments, please refer to Figure 10 and Figure 11 , and in conjunction with other figures. The second connecting structure 22 also includes a second sleeve 223 and a second filler 224. The second sleeve 223 is at least partially assembled within the second mounting hole 201. The second sleeve 223 is sleeved around the outer circumference of the second rotating member 222. The second filler 224 is filled between the second sleeve 223 and the second rotating member 222.

[0186] The second sleeve 223 is a component for mounting the second rotating member 222 and the second filling member 224 , and is substantially in the shape of a sleeve.

[0187] The second connecting seat 221 is sleeved on the outer periphery of the second sleeve 223 .

[0188] The second filling member 224 is a filling material filled between the second rotating member 222 and the second sleeve 223. The second filling member 224 can be, but is not limited to, a rubber layer.

[0189] The second filling member 224 is filled between the outer circumferential wall of the second rotating member 222 and the inner circumferential wall of the second sleeve 223. The second filling member 224 can be filled between the outer circumferential wall of the second ball head 2221 and the inner circumferential wall of the second sleeve 223, or between the outer circumferential wall of the second pin shaft 2222 and the inner circumferential wall of the second sleeve 223.

[0190] By adopting the above technical solution, the second sleeve 223, the second filler 224, and the second rotating member 222 can roughly form a bushing. This allows the second rotating member 222 to rotate relative to the second sleeve 223, thereby achieving rotation of the swing arm body 21 relative to the bracket body 11, thereby absorbing impact or vibration applied to the vehicle body from the ground. Furthermore, the second filler 224 is filled between the second sleeve 223 and the second rotating member 222, ensuring a stable assembly of the bushing formed by the second sleeve 223, the second filler 224, and the second rotating member 222. This provides a certain structural rigidity to the bushing, thereby providing a certain yaw stiffness between the swing arm structure 20 and the bracket structure 10.

[0191] It should be noted that when the second mounting hole 201 includes a second through hole section 2011 and a second groove section 2012, a second filling piece 224 and a second sleeve 223 can be arranged in the second mounting hole 201 to divide the second mounting hole 201 into the above-mentioned second through hole section 2011 and second groove section 2012.

[0192] In some embodiments, the second sleeve 223 is interference-fitted with the second mounting hole 201. This arrangement allows the bushing formed by the second sleeve 223, the second filler 224, and the second rotating member 222 to be securely assembled with the second connecting seat 221, thereby improving the yaw stiffness between the swing arm structure 20 and the bracket structure 10.

[0193] In some embodiments, as Figures 7 to 9 As shown, the second connection structure 22 may include the second connection seat 221 and the second rotating member 222, but not the second filling member 224 and the second sleeve 223. Alternatively, as Figure 10 and Figure 11 As shown, the second connection structure 22 may also include the second connection seat 221 , the second rotating member 222 , the second filling member 224 and the second sleeve 223 .

[0194] In some embodiments, the second rotating member 222 is a steel structure, an aluminum structure, or a nylon structure.

[0195] In some embodiments, the second sleeve 223 is a steel structure, an aluminum structure, or a nylon structure.

[0196] In some embodiments, the second connecting base 221 and the swing arm body 21 are integrally connected. As an example, the second connecting base 221 and the swing arm body 21 are both metal structures, and the second connecting base 221 and the swing arm body 21 can be integrally formed by stamping, die casting, pouring, etc.

[0197] In some other embodiments, the second connecting seat 221 and the swing arm body 21 may also be connected by welding, bolting, riveting, or the like.

[0198] In some embodiments, please refer to Figures 2 to 11 Along the axial direction X of the fastener 30 , the second connection structure 22 abuts between two adjacent first connection structures 12 .

[0199] As an example, Figures 2 to 6 As shown, when the first connection structure 12 includes the first rotating member 122 and the second connection structure 22 does not include the second rotating member 222 , the first rotating member 122 abuts against the second connection seat 221 along the axial direction X.

[0200] As an example, Figures 7 to 11 As shown, when the first connection structure 12 does not include the first rotating member 122 and the second connection structure 22 includes the second rotating member 222 , the second rotating member 222 abuts against the first connection seat 121 along the axial direction X.

[0201] As an example, when the first connection structure 12 includes the first rotating member 122 and the second connection structure 22 includes the second rotating member 222 , the first rotating member 122 abuts against the second rotating member 222 along the axial direction X.

[0202] Such arrangement enables the first connecting structure 12 and the second connecting structure 22 to abut against each other along the axial direction X, which helps to improve the connection stiffness between the first connecting structure 12 and the second connecting structure 22, thereby improving the yaw stiffness between the first connecting structure 12 and the second connecting structure 22, thereby improving the yaw stiffness between the swing arm body 21 and the bracket body 11.

[0203] In some embodiments, the swing arm structure 20 includes a plurality of second connection structures 22 , which are connected to the swing arm body 21 at intervals, and the first connection structure 12 is disposed between two adjacent second connection structures 22 .

[0204] Such an arrangement allows the first connecting structure 12 to be located between two adjacent second connecting structures 22 along the axial X limit, and the second connecting structure 22 to be located between two adjacent first connecting structures 12 along the axial X limit, which can greatly improve the connection stiffness between the first connecting structure 12 and the second connecting structure 22, thereby improving the yaw stiffness between the first connecting structure 12 and the second connecting structure 22, thereby improving the yaw stiffness between the swing arm body 21 and the bracket body 11.

[0205] In some embodiments, please refer to Figure 2 and Figure 7, and in conjunction with other drawings. The bracket body 11 is provided with a third mounting hole 102 along the axial direction X of the fastener 30, and the third mounting hole 102 is used to connect the wheel.

[0206] The third mounting hole 102 is a through hole that passes through the bracket body 11 along the axial direction X and is used to connect the wheel. The third mounting hole 102 and the first connecting seat 121 are spaced apart.

[0207] As an example, the third mounting hole 102 is used to connect to a hub bearing, thereby indirectly connecting to the hub of the wheel.

[0208] This arrangement allows the swing arm body 21's rotational axis relative to the support body 11 (i.e., the central axis L of the fastener 30) to be substantially parallel to the wheel axle. Thus, the suspension structure 400 provided in this embodiment of the present application, while allowing the swing arm body 21 to rotate relative to the support body 11 about the central axis L parallel to the wheel axle, can improve the yaw stiffness between the swing arm body 21 and the support body 11.

[0209] In some embodiments, please refer to Figure 2 and Figure 7 , and in combination with other drawings. The swing arm body 21 includes a rear swing arm. Or, as Figure 12 As shown, Figure 12 This is a partial three-dimensional structural diagram of the suspension structure 400 provided in some other embodiments of the present application, in which the swing arm body 21 includes a torsion beam rear axle swing arm.

[0210] Such an arrangement can improve the yaw stiffness between the rear swing arm and the bracket body 11; or, can improve the yaw stiffness between the torsion beam rear axle swing arm and the bracket body 11.

[0211] Please also refer to Figure 1 and Figure 2 , and in conjunction with other drawings. The vehicle 1000 provided in the embodiment of the present application includes a suspension structure 400. The suspension structure 400 in this embodiment is the same as the suspension structure 400 in the previous embodiment. For details, please refer to the relevant description of the suspension structure 400 in the previous embodiment, which will not be repeated here.

[0212] The vehicle 1000 provided in the embodiment of the present application can improve the yaw stiffness between the support structure 10 and the swing arm structure 20 by adopting the suspension structure 400 mentioned above, thereby improving the handling performance and usage comfort of the vehicle 1000.

[0213] As one of the embodiments of this application, Figures 2 to 6As shown, the suspension structure 400 includes a support structure 10, a swing arm structure 20, and a fastener 30. The support structure 10 includes a support body 11 and two first connecting structures 12, which are connected to the support body 11 at intervals along the axial direction X of the fastener 30. The first connecting structure 12 includes a first connecting seat 121 and a first rotating member 122. The first connecting seat 121 is connected to the support body 11 and has a first mounting hole 101 formed therethrough along the axial direction X of the fastener 30. The first rotating member 122 includes a first ball head 1221 and a first pin shaft portion 1222, which are connected along the axial direction X of the fastener 30. At least a portion of the first ball head 1221 is disposed in the first mounting hole 101, and the first rotating member 122 is rotatable relative to the first connecting seat 121. The swing arm structure 20 includes a swing arm body 21 and a second connecting structure 22. The second connecting structure 22 includes a second connecting seat 221 connected to the swing arm body 21. The fastener 30 is provided along the axial direction X through the first ball heads 1221 and the first pin shaft 1222 of the two first connection structures 12 and through the second connection seat 221 to rotatably connect the bracket body 11 and the swing arm body 21 .
