Among them, the bearing has a large stiffness, which helps to improve the connection stiffness between the first connection structure and the second connection structure, so as to improve the yaw stiffness between the first connection structure and the second connection structure, and thus helps to improve the yaw stiffness between the bracket structure and the swing arm structure.

The first inner ring is rotatable relative to the first outer ring, the first outer ring is connected to the swing arm body, and a fastener passes through the first inner ring.

[0016] Through the interference fit between the first bearing and the first mounting hole, the first bearing can be firmly assembled to the first connection seat, which helps to improve the connection stiffness and yaw stiffness between the first bearing and the first connection seat, and thus can improve the yaw stiffness between the swing arm structure and the bracket structure.

[0017] In some embodiments, the first connection seat and the swing arm body are an integral connection structure.

[0018] With such an arrangement, the connection strength between the first connection seat and the swing arm body can be improved, so as to improve the structural stiffness of the swing arm structure, and thus also helps to improve the yaw stiffness between the swing arm structure and the bracket structure.

[0019] In some embodiments, the second bearing includes a second inner ring and a second outer ring sleeved on the outer periphery of the second inner ring. The second inner ring is rotatable relative to the second outer ring, the second outer ring is connected to the bracket body, and a fastener passes through the second inner ring.

[0020] With such an arrangement, the connection stiffness between the first connection structure and the second connection structure can be improved, so as to improve the yaw stiffness between the first connection structure and the second connection structure, thereby contributing to improving the yaw stiffness between the bracket structure and the swing arm structure, and improving the vehicle's handling performance and use comfort.

[0021] In some embodiments, the second connection structure further includes a second connection seat connected to the bracket body, and the second connection seat is sleeved on the outer periphery of the second bearing.

[0022] By connecting to the bracket body through the second connection seat and being sleeved on the outer periphery of the second bearing, the connection stiffness and yaw stiffness between the second bearing and the bracket body can be improved, which helps to improve the yaw stiffness of the first connection structure and the second connection structure, and thus helps to improve the yaw stiffness between the bracket structure and the swing arm structure.

[0023] In some embodiments, the second connection seat is provided with a second mounting hole, and the second bearing is in interference fit with the second mounting hole.

[0024] Through the interference fit between the second bearing and the second mounting hole, the second bearing can be firmly assembled to the second connection seat, which helps to improve the connection stiffness and yaw stiffness between the second bearing and the second connection seat, and thus the yaw stiffness between the swing arm structure and the bracket structure can be improved.

[0025] In some embodiments, the second connection seat and the bracket body are an integral connection structure.

[0026] With such a setting, the connection strength between the second connection seat and the bracket body can be improved to increase the structural stiffness of the bracket structure, and thus it also helps to improve the yaw stiffness between the swing arm structure and the bracket structure.

[0027] In some embodiments, the first bearing is a metal structure; and / or the second bearing is a metal structure.

[0028] With such a setting, it helps to improve the connection stiffness and yaw stiffness of the first connection structure and the second connection structure, and thus helps to improve the swing stiffness between the bracket structure and the swing arm structure.

[0029] In some embodiments, the first connection structure includes a first bearing connected to the swing arm body, and a fastener passes through the first bearing; the second connection structure includes a third connection seat connected to the bracket body, and a fastener passes through the third connection seat.

[0030] By adopting the above technical solution, the setting of the first bearing can improve the yaw stiffness between the bracket structure and the swing arm structure. Moreover, the fastener passing through the third connection seat can simplify the structure of the bracket structure.

[0031] In some embodiments, the second connection structure further includes a first rotating member, and the third connection seat is provided with a third mounting hole penetrating along the axial direction of the fastener; at least part of the first rotating member is rotatably disposed in the third mounting hole, and the fastener passes through the first rotating member.

[0032] By passing a fastener through the first rotating member, the connection between the fastener and the first rotating member can be achieved. In this way, the fastener and the first rotating member can rotate together around the central axis of the fastener, enabling the swing arm structure to swing relative to the third connecting seat and the bracket body along with the fastener and the first rotating member to absorb the impact or vibration applied from the ground to the vehicle body.

[0033] In some embodiments, the first rotating member includes a first ball head portion, at least a part of which is rotatably disposed in the third mounting hole, and the fastener is passed through the first ball head portion.

[0034] By the first rotating member including the first ball head portion and at least a part of the first ball head portion being rotatably disposed in the third mounting hole, it is convenient for the first rotating member to rotate relative to the third connecting seat to absorb the impact or vibration applied from the ground to the wheel. Moreover, the setting of the first ball head portion makes the first rotating member have a relatively large stiffness, which helps to improve the connection stiffness between the first rotating member and the third connecting seat, so as to contribute to improving the yaw stiffness between the first rotating member and the third connecting seat, thereby improving the yaw stiffness between the bracket structure and the swing arm structure.

[0035] 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.

[0036] Through the setting of 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 and yaw stiffness between the first rotating member and the third connecting seat, thereby improving the yaw stiffness between the bracket structure and the swing arm structure.

[0037] In some embodiments, along the axial direction, first pin shaft portions are connected to both opposite ends of the first ball head portion.

[0038] With such a setting, the balance performance of the first rotating member can be improved to enhance the stability of the relative rotation between the bracket structure and the swing arm structure. In this way, it also contributes to the yaw stiffness between the first rotating member and the third connecting seat, thereby improving the yaw stiffness between the bracket structure and the swing arm structure.

[0039] In some embodiments, the third mounting hole includes a first through-hole section and a first groove section. The first through-hole section axially penetrates the third connecting seat, and the first groove section communicates with the outer periphery of the first through-hole section; a part of the first ball head portion is disposed in the first through-hole section, and the other part is axially limited in the first groove section.

[0040] By axially limiting another part of the first spherical head within the first groove section, the first rotating member can be axially and stably limited on the third connecting seat, so as to realize the stable connection between the first rotating member and the third connecting seat. In this way, it helps to improve the connection stiffness and yaw stiffness between the first rotating member and the third connecting seat, thereby improving the yaw stiffness between the bracket structure and the swing arm structure.

[0041] In some embodiments, the second connection structure further includes a first sleeve, at least part of the first sleeve is assembled in the third mounting hole, and the first sleeve is sleeved on the outer periphery of the first rotating member.

[0042] By providing the first sleeve, the first sleeve and the first rotating member can generally form a bushing structure. In this way, the first rotating member and the fastener can rotate relative to the first sleeve and the third connecting seat together.

[0043] In some embodiments, the second connection structure further includes a first filling member filled between the first rotating member and the first sleeve.

[0044] By filling the first filling member between the first sleeve and the first rotating member, the bushing structure formed by the first sleeve, the first filling member and the first rotating member can be stably assembled, so that the bushing structure has a certain structural stiffness, thereby enabling the swing arm structure and the bracket structure to have a certain yaw stiffness.

[0045] In some embodiments, the second connection structure includes a second bearing connected to the bracket body, and the fastener passes through the second bearing; the first connection structure includes a fourth connecting seat connected to the swing arm body, and the fastener passes through the fourth connecting seat.

[0046] By adopting the above technical solutions, the setting of the second bearing can improve the yaw stiffness between the bracket structure and the swing arm structure. Moreover, the fastener passes through the fourth connecting seat, which can simplify the structure of the swing arm structure.

[0047] In some embodiments, the first connection structure further includes a second rotating member, the fourth connecting seat is provided with a fourth mounting hole axially penetrating along the fastener; at least part of the second rotating member is rotatably arranged in the fourth mounting hole, and the fastener passes through the second rotating member.

[0048] By passing the fastener through the second rotating member, the connection between the fastener and the second rotating member can be realized. In this way, the fastener and the second rotating member can rotate together around the central axis of the fastener, so that the swing arm body and the fourth connecting seat can swing relative to the fastener, the second rotating member and the bracket structure to absorb the impact or vibration applied from the ground to the vehicle body.

[0049] 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 part of the second ball head portion is rotatably disposed in the fourth mounting hole, and a fastener is disposed through the second ball head portion and the second pin shaft portion.

[0050] By including a second ball head portion in the second rotating member and rotatably disposing at least a part of the second ball head portion in the fourth mounting hole, it is convenient for the second rotating member to rotate relative to the fourth connecting seat to absorb the impact or vibration applied to the wheel from the ground. Moreover, the arrangement of the second ball head portion and the second pin shaft portion makes the second rotating member have a relatively large stiffness, which helps to improve the connection stiffness and yaw stiffness between the second rotating member and the fourth connecting seat, thereby improving the yaw stiffness between the bracket structure and the swing arm structure.

[0051] In some embodiments, second pin shaft portions are connected to opposite ends of the second ball head portion along the axial direction.

[0052] With such an arrangement, the balance performance of the second rotating member can be improved to enhance the stability of the relative rotation between the bracket structure and the swing arm structure. In this way, it also contributes to the yaw stiffness between the second rotating member and the fourth connecting seat, thereby improving the yaw stiffness between the bracket structure and the swing arm structure.

[0053] In some embodiments, the fourth mounting hole includes a second through-hole section and a second groove section. The second through-hole section axially penetrates the fourth connecting seat, and the second groove section communicates with the outer periphery of the second through-hole section; a part of the second ball head portion is disposed in the second through-hole section, and the other part is axially limited in the second groove section.

[0054] By axially limiting the other part of the second ball head portion in the second groove section, the second rotating member can be stably axially limited on the fourth connecting seat to achieve a stable connection between the second rotating member and the fourth connecting seat. Thus, it helps to improve the connection stiffness and yaw stiffness between the second rotating member and the fourth connecting seat, thereby improving the yaw stiffness between the bracket structure and the swing arm structure.

[0055] In some embodiments, the first connection structure further includes:

[0056] A second sleeve, at least partially assembled in the fourth mounting hole, and the second sleeve is sleeved on the outer periphery of the second rotating member;

[0057] A second filling member, filled between the second sleeve and the second rotating member.

[0058] By adopting the above technical solution, the second rotating member can rotate relative to the second sleeve and the fourth connecting seat together with the fastener. By filling the second filling member between the second sleeve and the second rotating member, the bushing structure formed by the second sleeve, the second filling member and the second rotating member can be stably assembled, so that the bushing structure has a certain structural stiffness, thereby enabling a certain yaw stiffness between the swing arm structure and the bracket structure.

[0059] In some embodiments, the bracket structure includes a plurality of second connecting structures spaced and connected to the bracket body. The first connecting structure is limited between two adjacent second connecting structures, and the fastener is at least passed through two adjacent second connecting structures;

[0060] And / or, the swing arm body includes a plurality of first connecting structures spaced and connected to the swing arm body. The second connecting structure is limited between two adjacent first connecting structures, and the fastener is at least passed through two adjacent first connecting structures.

[0061] With such a setting, the connection stiffness and yaw stiffness between the first connecting structure and the second connecting structure can be improved, thereby improving the yaw stiffness between the bracket structure and the swing arm structure.

[0062] In some embodiments, along the axial direction of the fastener, one end of the first connecting structure close to the second connecting structure abuts against one end of the second connecting structure close to the first connecting structure.

[0063] With such a setting, the yaw stiffness between the first connecting structure and the second connecting structure can be improved to improve the yaw stiffness between the bracket structure and the swing arm structure.

[0064] In some embodiments, the bracket body is provided with a fifth mounting hole penetrating along the axial direction of the fastener, and the fifth mounting hole is used to connect the wheel.

[0065] With such a setting, the rotation axis of the swing arm body relative to the bracket body (i.e., the central axis of the above-mentioned fastener) is substantially parallel to the wheel axle. In this way, for the suspension structure provided by the embodiments of the present application, on the basis that the swing arm body can rotate relative to the bracket body around a central axis parallel to the wheel axle, the yaw stiffness between the swing arm body and the bracket body can be improved.

[0066] In some embodiments, the swing arm body includes a rear swing arm or a torsion beam rear axle swing arm.

[0067] With such a setting, the yaw stiffness between the rear swing arm and the bracket body can be improved; or, the yaw stiffness between the torsion beam rear axle swing arm and the bracket body can be improved.

[0143] The first bearing 121 is press-fitted with the first mounting hole 101, so that the first bearing 121 can be firmly assembled to the first connecting seat 122, which helps to improve the connection stiffness and yaw stiffness between the first bearing 121 and the first connecting seat 122, thereby improving the yaw stiffness between the swing arm structure 10 and the bracket structure 20.

[0144] In some embodiments, the first connecting seat 122 and the swing arm body 11 are integrally connected structures.

[0145] As an example, both the first connecting seat 122 and the swing arm body 11 are metal structures, and the first connecting seat 122 and the swing arm body 11 can be integrally formed by stamping, die-casting, pouring, etc.

The second inner ring 2211 can rotate relative to the second outer ring 2212, and the fastener 30 passes through the second inner ring 2211. Based on this, the fastener 30, the bracket structure 20 and the second inner ring 2211 can rotate relative to the second outer ring 2212, the second connecting seat 222 and the swing arm body 11, so that the swing arm body 11 can rotate relative to the bracket body 21 around the central axis L of the fastener 30.

[0152] It can be understood that structures such as balls can also be provided between the second inner ring 2211 and the second outer ring 2212.

[0153] With such a setting, the connection stiffness between the first connection structure 12 and the second connection structure 22 can be improved, so as to increase the yaw stiffness between the first connection structure 12 and the second connection structure 22, thereby contributing to improving the yaw stiffness between the bracket structure 20 and the swing arm structure 10, and improving the handling performance and use comfort of the vehicle 1000.

[0154] In some embodiments, please refer to Figure 5 and Figure 6 together, and in combination with other drawings. The second connection structure 22 further includes a second connection seat 222, and the second connection seat 222 is connected to the bracket body 21 and sleeved on the outer periphery of the second bearing 221.

[0155] The second connection seat 222 is a component on the second connection structure 22 for connecting to the bracket body 21.

[0156] Specifically, the second connection seat 222 is generally in a sleeve shape and is sleeved on the outer periphery of the second outer ring 2212. Among them, the second connection seat 222 is connected to the bracket body 21, specifically, the second connection seat 222 and the bracket body 21 are fixedly connected.

[0157] By connecting the second connection seat 222 to the bracket body 21 and sleeving it on the outer periphery of the second bearing 221, the connection stiffness and yaw stiffness between the second bearing 221 and the bracket body 21 can be improved, which helps to improve the yaw stiffness between the first connection structure 12 and the second connection structure 22, and thus helps to improve the yaw stiffness between the bracket structure 20 and the swing arm structure 10.

[0159] The second mounting hole 201 is a through hole that penetrates the second connection seat 222 along the axial direction X of the fastener 30, and the second mounting hole 201 is used to mount the second bearing 221.

[0160] Specifically, the setting of the second mounting hole 201 makes the second connection seat 222 generally in a sleeve shape. The second outer ring 2212 of the second bearing 221 is arranged in the second mounting hole 201, and the outer peripheral wall of the second outer ring 2212 and the inner peripheral wall of the second mounting hole 201 are in mutual abutment, so that the second bearing 221 is in interference fit with the second mounting hole 201.

[0161] By means of the interference fit between the second bearing 221 and the second mounting hole 201, the second bearing 221 can be firmly assembled to the second connecting seat 222, which helps to improve the connection stiffness and yaw stiffness between the second bearing 221 and the second connecting seat 222, thereby improving the yaw stiffness between the swing arm structure 10 and the bracket structure 20.

[0162] In some embodiments, the second connecting seat 222 and the bracket body 21 are integrally connected structures.

[0163] As an example, both the second connecting seat 222 and the bracket body 21 are metal structures, and the second connecting seat 222 and the bracket body 21 can be integrally formed by stamping, die-casting, casting and other methods.

[0164] With such a setting, the connection strength between the second connecting seat 222 and the bracket body 21 can be improved to increase the structural stiffness of the bracket structure 20, which also helps to improve the yaw stiffness between the swing arm structure 10 and the bracket structure 20.

[0165] In some other embodiments, the second connecting seat 222 and the bracket body 21 can also be connected by welding, bolt fixing, riveting fixing and other methods.

[0166] Among them, the second connecting seat 222 and the bracket body 21 can form the bracket involved above.

[0167] In some embodiments, the first bearing 121 is a metal structure.

[0168] It can be understood that at least part of the material of the first bearing 121 is metal, which can be but is not limited to steel. As an example, the first bearing 121 is a steel bearing.

[0169] In this way, the first bearing 121 has a relatively large structural stiffness.

[0170] In some embodiments, the second bearing 221 is a metal structure.

[0171] It can be understood that at least part of the material of the second bearing 221 is metal, which can be but is not limited to steel. As an example, the second bearing 221 is a steel bearing.

[0172] In this way, the second bearing 221 has a relatively large structural stiffness.

[0173] With such a setting, it helps to improve the connection stiffness and yaw stiffness between the first connection structure 12 and the second connection structure 22, thereby helping to improve the swing stiffness between the bracket structure 20 and the swing arm structure 10.

[0174] In some embodiments, please refer to Figures 2 to 4, and in combination with other attached drawings. The first connection structure 12 includes a first bearing 121, the first bearing 121 is connected to the swing arm body 11, and the fastener 30 is inserted through the first bearing 121. The second connection structure 22 includes a third connection seat 223, the third connection seat 223 is connected to the bracket body 21, and the fastener 30 is inserted through the third connection seat 223.

[0177] The fastener 30 is inserted through the third connection seat 223, and can be fixedly connected to the third connection seat 223 or rotatably connected to the third connection seat 223.

[0178] By adopting the above technical solution, the setting of the first bearing 121 can improve the yaw stiffness between the bracket structure 20 and the swing arm structure 10. And, the fastener 30 is inserted through the third connection seat 223, which can simplify the structure of the bracket structure 20.

[0179] Among them, the third connection seat 223 and the bracket body 21 can form the bracket involved above.

[0180] In some embodiments, please refer to Figures 7 to 9 , and in combination with other attached drawings. Among them, Figure 7 is a three-dimensional structure diagram of the suspension structure 400 provided by some other embodiments of the present application, Figure 8 is Figure 7 a cross-sectional view along D-D, Figure 9 is Figure 8 an enlarged view of the E position in . The second connection structure 22 further includes a first rotating member 224. The third connection seat 223 is provided with a third mounting hole 202 penetrating along the axial direction X of the fastener 30. At least part of the first rotating member 224 is rotatably disposed in the third mounting hole 202, and the fastener 30 is inserted through the first rotating member 224.

[0181] The third mounting hole 202 is a through hole penetrating the third connection seat 223 along the axial direction X of the fastener 30, and the third mounting hole 202 is used to mount the first rotating member 224.

[0182] The first rotating member 224 is a component that can rotate relative to the third connection seat 223. Among them, at least part of the first rotating member 224 is disposed in the third mounting hole 202, and the first rotating member 224 can rotate around the central axis L of the fastener 30 relative to the third mounting hole 202.

[0183] The fastener 30 is inserted through the first rotating member 224. Specifically, the fastener 30 is inserted through the first rotating member 224 along the axial direction X, so as to realize that the fastener 30 is inserted through the third connecting seat 223 along the axial direction X. Among them, the fastener 30 is inserted through the first rotating member 224 to be fixedly connected with the first rotating member 224.

[0184] By passing the fastener 30 through the first rotating member 224, the connection between the fastener 30 and the first rotating member 224 can be realized. In this way, the fastener 30 and the first rotating member 224 can rotate together around the central axis L of the fastener 30, so that the swing arm structure 10 can swing relative to the third connecting seat 223 and the bracket body 21 along with the fastener 30 and the first rotating member 224 to absorb the impact or vibration applied to the vehicle body from the ground.

[0185] In some embodiments, please refer to Figures 10 to 12 together and in combination with other drawings. Among them, Figure 10 is a three-dimensional structure diagram of the suspension structure 400 provided in still other embodiments of the present application, Figure 11 is Figure 10 a cross-sectional view along F-F, Figure 12 is Figure 11 an enlarged view at G in

[0186] The first ball head 2241 is at least part of the first rotating member 224, and the first ball head 2241 is generally in a ball head shape.

[0187] Among them, at least part of the first ball head 2241 is arranged in the third mounting hole 202, and the first ball head 2241 can rotate relative to the third mounting hole 202 around the central axis L of the fastener 30.

[0188] The fastener 30 is inserted through the first ball head 2241 along the axial direction X to be fixedly connected with the first ball head 2241.

[0189] Since the first rotating member 224 includes the first ball head 2241 and at least part of the first ball head 2241 is rotatably arranged in the third mounting hole 202, it is convenient for the first rotating member 224 to rotate relative to the third connecting seat 223 to absorb the impact or vibration applied to the wheel from the ground. Moreover, the setting of the first ball head 2241 makes the first rotating member 224 have greater rigidity, which helps to improve the connection rigidity between the first rotating member 224 and the third connecting seat 223, so as to help improve the yaw stiffness between the first rotating member 224 and the third connecting seat 223, and thus the yaw stiffness between the bracket structure 20 and the swing arm structure 10 can be improved.

[0190] In some embodiments, please refer to Figures 10 to 12 together with other drawings. The first rotating member 224 further includes a first pin shaft portion 2242. The first pin shaft portion 2242 and the first ball head portion 2241 are connected along the axial direction X. The fastener 30 is inserted through the first pin shaft portion 2242.

[0191] The first pin shaft portion 2242 is a part of the structure of the first rotating member 224. The first pin shaft portion 2242 is generally shaft-shaped.

[0192] Wherein, the first pin shaft portion 2242 and the first ball head portion 2241 are distributed and connected along the axial direction X. The fastener 30 is inserted through the first pin shaft portion 2242 and the first ball head portion 2241 along the axial direction X, so that the fastener 30 is inserted through the first rotating member 224 along the axial direction X.

[0193] Based on the fact that the first rotating member 224 includes the first ball head portion 2241 and the first pin shaft portion 2242, it can be understood that the first rotating member 224 is generally a ball pin.

[0194] Through the arrangement of the first ball head portion 2241 and the first pin shaft portion 2242, the structural stiffness of the first rotating member 224 can be improved, which helps to improve the connection stiffness and yaw stiffness between the first rotating member 224 and the third connection seat 223, thereby improving the yaw stiffness between the bracket structure 20 and the swing arm structure 10.

[0195] It should be supplemented here that the first pin shaft can be radially limited to the first connection seat 122 along the radial direction Y of the fastener 30, which helps to improve the connection stiffness between the first connection structure 12 and the second connection structure 22.

[0196] Wherein, unless otherwise specified below, the radial direction Y of the fastener 30 can be simply referred to as the radial direction Y.

[0197] In some embodiments, at least a part of the first pin shaft can be located outside the third mounting hole 202.

[0198] In some embodiments, please refer to Figures 10 to 12 together with other drawings. Along the axial direction X, both opposite ends of the first ball head portion 2241 are connected with the first pin shaft portion 2242.

[0199] With such an arrangement, the balance performance of the first rotating member 224 can be improved to improve the stability of the relative rotation between the bracket structure 20 and the swing arm structure 10. In this way, it also helps to improve the yaw stiffness between the first rotating member 224 and the third connection seat 223, thereby improving the yaw stiffness between the bracket structure 20 and the swing arm structure 10.

[0200] In some embodiments, please refer to Figures 10 to 12, and in combination with other drawings. The third mounting hole 202 includes a first through-hole section 2021 and a first groove section 2022. The first through-hole section 2021 axially penetrates the third connecting seat 223 along the X-axis, and the first groove section 2022 communicates with the outer periphery of the first through-hole section 2021. A part of the first ball head 2241 is disposed in the first through-hole section 2021, and the other part is axially limited in the first groove section 2022 along the X-axis.

[0201] The first through-hole section 2021 and the first groove section 2022 are two parts of the third mounting hole 202. Among them, the first groove section 2022 surrounds the outer periphery of the first through-hole section 2021, and the first groove section 2022 communicates with the first through-hole section 2021.

[0202] Specifically, the first ball head 2241 and the first groove section 2022 are in concave-convex fit along the radial Y of the fastener 30, so that the other part of the first ball head 2241 is axially limited in the first groove section 2022 along the X-axis.

[0203] By axially limiting the other part of the first ball head 2241 in the first groove section 2022 along the X-axis, the first rotating member 224 can be stably axially limited on the third connecting seat 223 to achieve a stable connection between the first rotating member 224 and the third connecting seat 223. In this way, it helps to improve the connection stiffness and yaw stiffness between the first rotating member 224 and the third connecting seat 223, thereby improving the yaw stiffness between the bracket structure 20 and the swing arm structure 10.

[0204] In some embodiments, at least part of the first pin portion 2242 can be disposed in the first through-hole section 2021.

[0205] In some embodiments, please refer to Figures 7 to 9 , and in combination with other drawings. The second connecting structure 22 further includes a first sleeve 225. At least part of the first sleeve 225 is assembled in the third mounting hole 202, and the first sleeve 225 is sleeved on the outer periphery of the first rotating member 224.

[0206] The first sleeve 225 is a component for installing the first rotating member 224 and is generally in the shape of a sleeve.

[0207] At least part of the first sleeve 225 is assembled in the third mounting hole 202, so that the third connecting seat 223 is sleeved on the outer periphery of the first sleeve 225.

[0208] It can be understood that in the radial Y direction, the first sleeve 225 is disposed between the inner peripheral wall of the third connecting seat 223 and the outer peripheral wall of the first rotating member 224.

[0209] By providing the first sleeve 225, the first sleeve 225 and the first rotating member 224 can generally form a bushing structure. In this way, the first rotating member 224 and the fastener 30 can rotate relative to the first sleeve 225 and the third connecting seat 223 together.

[0210] It should be supplemented here that when the third mounting hole 202 includes a first through-hole section 2021 and a first groove section 2022, the first sleeve 225 can divide the third mounting hole 202 into the above-mentioned first through-hole section 2021 and first groove section 2022 within the third mounting hole 202.

[0211] In some embodiments, please refer to Figures 10 to 12 , and in combination with other drawings. The second connection structure 22 further includes a first filling member 226, and the first filling member 226 is filled between the first rotating member 224 and the first sleeve 225.

[0212] The first filling member 226 refers to the filling material filled between the first sleeve 225 and the first rotating member 224. Among them, the first filling member 226 can be, but is not limited to, a rubber layer.

[0213] As an example, the first filling member 226 can be filled between the inner peripheral wall of the first sleeve 225 and the outer peripheral wall of the first rotating member 224. Based on this, the first rotating member 224, the first filling member 226 and the first sleeve 225 can generally form a bushing structure.

[0214] By filling the first filling member 226 between the first sleeve 225 and the first rotating member 224, the bushing structure formed by the first sleeve 225, the first filling member 226 and the first rotating member 224 can be stably assembled, so that the bushing structure has a certain structural stiffness, thereby enabling a certain yaw stiffness between the swing arm structure 10 and the bracket structure 20.

[0215] It should be supplemented here that when the third mounting hole 202 includes a first through-hole section 2021 and a first groove section 2022, the first sleeve 225 and the first filling member 226 can divide the third mounting hole 202 into the above-mentioned first through-hole section 2021 and first groove section 2022 within the third mounting hole 202.

[0216] In some embodiments, the first rotating member 224 is made of steel structure, aluminum structure or nylon structure. And the first sleeve 225 is made of steel structure, aluminum structure or nylon structure.

[0217] With such arrangement, both the first rotating member 224 and the first sleeve 225 have relatively large structural stiffness, thereby improving the connection stiffness and yaw stiffness between the first rotating member 224 and the third connecting seat 223, and further improving the yaw stiffness between the bracket structure 20 and the swing arm structure 10.

[0218] In some embodiments, please refer to Figure 5 and Figure 6 together, and in combination with other drawings. The second connection structure 22 includes a second bearing 221, the second bearing 221 is connected to the bracket body 21, and the fastener 30 is inserted through the second bearing 221. The first connection structure 12 includes a fourth connection seat 123, the fourth connection seat 123 is connected to the swing arm body 11, and the fastener 30 is inserted through the fourth connection seat 123.

[0219] The fourth connection seat 123 is a component on the first connection structure 12 for connecting to the swing arm body 11.

[0220] Among them, the fourth connection seat 123 can be integrally connected to the swing arm body 11 by stamping, die-casting, pouring, etc., or can be separately connected to the swing arm body 11 by welding, bolt fixing, etc.

[0221] The fastener 30 is inserted through the fourth connection seat 123, and can be fixedly connected to the fourth connection seat 123 or rotatably connected to the fourth connection seat 123.

[0222] By adopting the above technical solutions, the setting of the second bearing 221 can improve the yaw stiffness between the bracket structure 20 and the swing arm structure 10. Moreover, the fastener 30 is inserted through the fourth connection seat 123, which can simplify the structure of the swing arm structure 10.

[0223] Among them, the fourth connection seat 123 and the swing arm body 11 can form the above-mentioned bracket.

[0224] In some embodiments, please refer to Figure 5 and Figure 6 together, and in combination with other drawings. The first connection structure 12 further includes a second rotating member 124. The fourth connection seat 123 is provided with a fourth mounting hole 102 penetrating along the axial direction X of the fastener 30. At least a part of the second rotating member 124 is rotatably disposed in the fourth mounting hole 102, and the fastener 30 is inserted through the second rotating member 124.

[0225] The fourth mounting hole 102 is a through hole penetrating the fourth connection seat 123 along the axial direction X of the fastener 30, and the fourth mounting hole 102 is used for mounting the second rotating member 124.

[0226] The second rotating member 124 is a member that can rotate relative to the fourth connecting seat 123. At least a part of the second rotating member 124 is disposed in the fourth mounting hole 102, and the second rotating member 124 can rotate around the central axis L of the fastener 30 relative to the fourth mounting hole 102.

[0227] The fastener 30 passes through the second rotating member 124. Specifically, the fastener 30 passes through the second rotating member 124 along the axial direction X, so as to realize that the fastener 30 passes through the fourth connecting seat 123 along the axial direction X. Among them, the fastener 30 passes through the second rotating member 124 to be fixedly connected with the second rotating member 124.

[0228] By passing the fastener 30 through the second rotating member 124, the connection between the fastener 30 and the second rotating member 124 can be realized. In this way, the fastener 30 and the second rotating member 124 can rotate together around the central axis L of the fastener 30, so that the swing arm body 11 and the fourth connecting seat 123 can swing relative to the fastener 30, the second rotating member 124 and the bracket structure 20 to absorb the impact or vibration applied to the vehicle body from the ground.

[0229] In some embodiments, please refer to Figure 5 and Figure 6 and other attached drawings. The second rotating member 124 includes a second ball head portion 1241 and a second pin portion 1242, and the second pin portion 1242 and the second ball head portion 1241 are connected along the axial direction X. At least a part of the second ball head portion 1241 is rotatably disposed in the fourth mounting hole 102, and the fastener 30 passes through the second ball head portion 1241 and the second pin portion 1242.

[0230] The second ball head portion 1241 and the second pin portion 1242 are two parts of the second rotating member 124. Among them, the second ball head portion 1241 is generally spherical, and the second pin portion 1242 is generally shaft-shaped.

[0231] Among them, at least a part of the second ball head portion 1241 is disposed in the fourth mounting hole 102, and the second ball head portion 1241 can rotate around the central axis L of the fastener 30 relative to the fourth mounting hole 102.

[0232] Based on the fact that the second rotating member 124 includes the second ball head portion 1241 and the second pin portion 1242, it can be understood that the second rotating member 124 is generally a ball pin.

[0233] Among them, the second pin portion 1242 and the second ball head portion 1241 are distributed and connected along the axial direction X. The fastener 30 passes through the second pin portion 1242 and the second ball head portion 1241 along the axial direction X, realizing that the fastener 30 passes through the second rotating member 124 along the axial direction X.

[0234] The fastener 30 is axially inserted through the second spherical head portion 1241 and the second pin shaft portion 1242 along the axial direction X, so that the fastener 30 is fixedly connected to the second spherical head portion 1241 and the second pin shaft portion 1242.

[0235] The second rotating member 124 includes a second spherical head portion 1241, and at least a part of the second spherical head portion 1241 is rotatably disposed in the fourth mounting hole 102, facilitating the rotation of the second rotating member 124 relative to the fourth connecting seat 123 to absorb the impact or vibration applied to the wheel from the ground. Moreover, the arrangement of the second spherical head portion 1241 and the second pin shaft portion 1242 enables the second rotating member 124 to have a relatively large stiffness, which helps to improve the connection stiffness and yaw stiffness between the second rotating member 124 and the fourth connecting seat 123, thereby improving the yaw stiffness between the bracket structure 20 and the swing arm structure 10.

[0236] It should be supplemented here that the second pin shaft can be radially limited to the fourth connecting seat 123 along the radial direction Y of the fastener 30, which helps to improve the connection stiffness between the first connection structure 12 and the second connection structure 22.

[0237] In some embodiments, at least a part of the second pin shaft can be located outside the fourth mounting hole 102.

[0238] In some embodiments, please refer to Figure 5 and Figure 6 , and in combination with other drawings. Along the axial direction X, both opposite ends of the second spherical head portion 1241 are connected with the second pin shaft portion 1242.

[0239] With such an arrangement, the balance performance of the second rotating member 124 can be improved to enhance the stability of the relative rotation between the bracket structure 20 and the swing arm structure 10. In this way, it also helps to improve the yaw stiffness between the second rotating member 124 and the fourth connecting seat 123, thereby improving the yaw stiffness between the bracket structure 20 and the swing arm structure 10.

[0240] In some embodiments, please refer to Figure 5 and Figure 6 , and in combination with other drawings. The fourth mounting hole 102 includes a second through-hole section 1021 and a second groove section 1022. The second through-hole section 1021 axially penetrates the fourth connecting seat 123, and the second groove section 1022 communicates with the outer periphery of the second through-hole section 1021. One part of the second spherical head portion 1241 is disposed in the second through-hole section 1021, and the other part of the second spherical head portion 1241 is axially limited in the second groove section 1022.

[0241] The second through-hole section 1021 and the second groove section 1022 are two parts of the fourth mounting hole 102. Among them, the second groove section 1022 surrounds the outer periphery of the second through-hole section 1021, and the second groove section 1022 communicates with the second through-hole section 1021.

[0242] Specifically, the second spherical head portion 1241 and the second groove section 1022 are in concave-convex fit along the radial direction Y of the fastener 30, so that the other part of the second spherical head portion 1241 is axially limited within the second groove section 1022 along the axial direction X.

[0243] By axially limiting the other part of the second spherical head portion 1241 within the second groove section 1022 along the axial direction X, the second rotating member 124 can be stably axially limited on the fourth connecting seat 123 to achieve a stable connection between the second rotating member 124 and the fourth connecting seat 123. In this way, it helps to improve the connection stiffness and yaw stiffness between the second rotating member 124 and the fourth connecting seat 123, thereby improving the yaw stiffness between the bracket structure 20 and the swing arm structure 10.

[0244] In some embodiments, at least a part of the second pin portion 1242 can also be disposed within the second through-hole section 1021.

[0245] In some embodiments, please refer to Figure 5 and Figure 6 , and in combination with other drawings. The first connection structure 12 further includes a second sleeve 125 and a second filling member 126. At least a part of the second sleeve 125 is assembled within the fourth mounting hole 102, and the second sleeve 125 is sleeved on the outer periphery of the second rotating member 124. The second filling member 126 is filled between the second sleeve 125 and the second rotating member 124.

[0246] The second sleeve 125 is a component for mounting the second rotating member 124 and is generally in the shape of a sleeve.

[0247] At least a part of the second sleeve 125 is assembled within the fourth mounting hole 102, so that the fourth connecting seat 123 is sleeved on the outer periphery of the second sleeve 125.

[0248] It can be understood that in the radial direction Y, the second sleeve 125 is disposed between the inner peripheral wall of the fourth connecting seat 123 and the outer peripheral wall of the second rotating member 124.

[0249] The second filling member 126 refers to a filling material filled between the second sleeve 125 and the second rotating member 124. Among them, the second filling member 126 can be but is not limited to a rubber layer.

[0250] As an example, the second filling member 126 can be filled between the inner peripheral wall of the second sleeve 125 and the outer peripheral wall of the second rotating member 124. Based on this, the second rotating member 124, the second filling member 126, and the second sleeve 125 can generally form a bushing structure.

[0251] By adopting the above technical solution, the second rotating member 124 can rotate relative to the second sleeve 125 and the fourth connecting seat 123 together with the fastener 30. By filling the second filling member 126 between the second sleeve 125 and the second rotating member 124, the bushing structure formed by the second sleeve 125, the second filling member 126, and the second rotating member 124 can be stably assembled, so that the bushing structure has a certain structural stiffness, thereby enabling the swing arm structure 10 and the bracket structure 20 to have a certain yaw stiffness.

[0252] It should be supplemented here that in the case where the fourth mounting hole 102 includes a second through-hole section 1021 and a second groove section 1022, the second sleeve 125 and the second filling member 126 can be within the fourth mounting hole 102, dividing the fourth mounting hole 102 into the above-mentioned second through-hole section 1021 and second groove section 1022.

[0253] In some embodiments, the second rotating member 124 is made of a steel structure, an aluminum structure, or a nylon structure. Moreover, the second sleeve 125 is made of a steel structure, an aluminum structure, or a nylon structure.

[0254] With such a setting, both the second rotating member 124 and the second sleeve 125 have a relatively large structural stiffness, thereby improving the connection stiffness and yaw stiffness between the second rotating member 124 and the fourth connecting seat 123, and thus improving the yaw stiffness between the bracket structure 20 and the swing arm structure 10.

[0255] In some embodiments, please refer to Figures 2 to 4 、 Figures 10 to 12 together and in combination with other drawings. The bracket structure 20 includes a plurality of second connection structures 22, and the plurality of second connection structures 22 are spaced and connected to the bracket body 21. The first connection structure 12 is limited between two adjacent second connection structures 22, and the fastener 30 penetrates at least two adjacent second connection structures 22.

[0256] Specifically, at least some of the second connection structures 22 are spaced apart along the axial direction X. In the axial direction X, the first connection structure 12 is limited between two adjacent second connection structures 22. Based on this, the first connection structure 12 and the second connection structures 22 are distributed along the axial direction X.

[0257] The fastener 30 axially passes through the first connection structure 12 and two adjacent second connection structures 22 along the axis X to connect the first connection structure 12 and the second connection structure 22 together, realizing the rotational connection between the bracket body 21 and the swing arm body 11.

[0258] As an example, the bracket structure 20 includes two of the above-mentioned second connection structures 22, and the two second connection structures 22 are spaced and connected to the bracket body 21 along the axis X. The first connection structure 12 is axially limited between the two second connection structures 22, and the fastener 30 axially passes through the first connection structure 12 and the two second connection structures 22.

[0259] By axially limiting the first connection structure 12 between two adjacent second connection structures 22 and passing the fastener 30 through the first connection structure 12 and two adjacent second connection structures 22, the first connection structure 12 and two adjacent second connection structures 22 are connected together to realize the rotational connection between the swing arm body 11 and the bracket body 21.

[0260] In some embodiments, the swing arm body 11 includes a plurality of first connection structures 12, and the plurality of first connection structures 12 are spaced and connected to the swing arm body 11. The second connection structure 22 is limited between two adjacent first connection structures 12, and the fastener 30 at least passes through two adjacent first connection structures 12.

[0261] By axially limiting the second connection structure 22 between two adjacent first connection structures 12 and passing the fastener 30 through the second connection structure 22 and two adjacent first connection structures 12, the second connection structure 22 and two adjacent first connection structures 12 are connected together to realize the rotational connection between the swing arm body 11 and the bracket body 21.

[0262] With such an arrangement, the connection stiffness and yaw stiffness between the first connection structure 12 and the second connection structure 22 can be improved, thereby improving the yaw stiffness between the bracket structure 20 and the swing arm structure 10.

[0263] In some embodiments, please refer to Figures 2 to 10 , and in combination with other drawings. Along the axis X of the fastener 30, one end of the first connection structure 12 close to the second connection structure 22 abuts against one end of the second connection structure 22 close to the first connection structure 12.

[0264] It can be understood that the first connection structure 12 axially abuts against the second connection structure 22.

[0265] With such an arrangement, the yaw stiffness between the first connection structure 12 and the second connection structure 22 can be improved to improve the yaw stiffness between the bracket structure 20 and the swing arm structure 10.

[0266] In some embodiments, please refer to Figure 2 、 Figure 7 and Figure 10 simultaneously, and in combination with other attached drawings.

[0267] The fifth mounting hole 203 is a through hole penetrating the bracket body 21 along the axial direction X and is used for connecting the wheel. Among them, the fifth mounting hole 203 and the second connecting structure 22 are distributed at intervals.

[0268] As an example, the fifth mounting hole 203 is used for connecting the hub bearing, and thus is indirectly connected to the hub of the wheel.

[0269] With such a setting, the rotation axis of the swing arm body 11 relative to the bracket body 21 (i.e., the central axis L of the above-mentioned fastener 30) is substantially parallel to the wheel axle. In this way, for the suspension structure 400 provided by the embodiments of the present application, on the basis that the swing arm body 11 can rotate relative to the bracket body 21 around the central axis L parallel to the wheel axle, the yaw stiffness between the swing arm body 11 and the bracket body 21 can be improved.

[0272] Please refer to Figure 1 and Figure 2 simultaneously, and in combination with other attached drawings. The vehicle 1000 provided by the embodiments of the present application includes a suspension structure 400. Among them, the suspension structure 400 in this embodiment is the same as the suspension structure 400 in the previous embodiment.
