[0053] Combine the following Figure 1-Figure 4 The suspension structure 100 according to an embodiment of the present invention is described in detail. The suspension structure 100 can be applied to a vehicle, but the present application is not limited thereto. The suspension structure 100 can be applied to other equipment that requires the suspension structure 100. The present application is described by taking the application of the suspension structure 100 to a vehicle as an example.

[0054] like Figure 1 and Figure 2As shown, the suspension structure 100 according to the embodiment of the present invention includes a first connecting arm 21, a second connecting arm 22 and a driving mechanism 3. The first connecting arm 21 is suitable for connecting to the vehicle body, one end of the second connecting arm 22 is rotatably connected to the first connecting arm 21, and the other end of the second connecting arm 22 is suitable for connecting to the wheel. The driving mechanism 3 is connected between the first connecting arm 21 and the second connecting arm 22, and the driving mechanism 3 can drive the second connecting arm 22 to rotate relative to the first connecting arm 21 to adjust the distance from the plane where the connection point of the first connecting arm 21 and the vehicle body is located to the plane where the connection point of the second connecting arm 22 and the wheel is located, so as to achieve the effect of vibration reduction of the suspension structure 100 and change the vehicle body height, thereby facilitating the improvement of the driving comfort and stability of the vehicle, and at the same time facilitating the increase of the movement stroke of the suspension structure 100, and the increase of the range of the suspension structure 100 to adjust the vehicle body height, thereby facilitating the improvement of the vibration reduction effect of the suspension structure 100. In addition, the suspension structure 100 has a simple and compact structure and a small volume, so that the space used for arranging the suspension structure 100 is small, which is beneficial to the space arrangement of the vehicle and improves the utilization of the vehicle space.

[0055] In the suspension structure 100 of the present invention, the driving mechanism 3 is arranged between the first connecting arm 21 and the second connecting arm 22. The driving mechanism 3 is used to drive the second connecting arm 22 to rotate relative to the first connecting arm 21. The distance from the plane where the connection point between the first connecting arm 21 and the vehicle body is located to the plane where the connection point between the second connecting arm 21 and the wheel 200 is located is magnified, so that the stroke requirement of the driving mechanism 3 is smaller, so that a smaller driving mechanism 3 can achieve the function of adjusting the height of the vehicle body, which greatly reduces the size of the driving mechanism 3 in the vehicle height direction, thereby greatly reducing the weight of the driving mechanism 3, thereby reducing the weight of the suspension structure 100, and the suspension structure 100 makes the suspension structure 100 simple, compact and small in size, so that the space used to arrange the suspension structure 100 is smaller, which is beneficial to the space arrangement of the vehicle and improves the utilization of the vehicle space.

[0056] In some embodiments of the present invention, the transmission shaft 20 is transmission-connected to the wheel 200 of the vehicle, and the other end of the second connecting arm 22 is sleeved on the outside of the transmission shaft 20. Along the circumference of the transmission shaft 20, the transmission shaft 20 rotates relative to the second connecting arm 22, thereby achieving the effect that the transmission shaft 20 is rotatably assembled on the second connecting arm 22, which is beneficial to achieving the rolling effect of the wheel 200.

[0057] Both ends of the first connecting arm 21 are fixedly connected to the vehicle body, thereby limiting the relative position of the first connecting arm 21 and the vehicle body, that is, the first connecting arm 21 is stationary relative to the vehicle body.

[0058] The second connecting arm 22 is rotatably connected to the first connecting arm 21. When the wheel 200 moves up and down, the second connecting arm 22 rotates relative to the first connecting arm 21 to increase or decrease the spacing distance between the second connecting arm 22 and the first connecting arm 21, so that the second connecting arm 22 is mounted on one end of the transmission shaft 20 and moves along the height direction of the suspension structure 100, thereby achieving the effect of moving the wheel 200 up and down.

[0059] Furthermore, when the vehicle is a mountain bike or a logistics vehicle, both ends of the first connecting arm 21 and the suspension structure 100 can be fixed to the outside of the vehicle body, so as to avoid the suspension structure 100 occupying the passenger compartment space of the vehicle, which is beneficial to the layout of the passenger compartment space and improves the utilization of the passenger compartment space.

[0060] The driving mechanism 3 is used to drive the second connecting arm 22 to rotate relative to the first connecting arm 21, so that in the height direction of the vehicle, the second connecting arm 22 has a tendency to rotate toward the direction close to the first connecting arm 21, and the second connecting arm 22 has a tendency to rotate toward the direction away from the first connecting arm 21, so as to achieve the effect that the second connecting arm 22 is sleeved on one end of the transmission shaft 20 and moves up and down along the height direction of the vehicle, that is, when the second connecting arm 22 rotates toward the direction close to the first connecting arm 21, the second connecting arm 22 is sleeved on one end of the transmission shaft 20 and moves upward along the height direction of the vehicle, and when the second connecting arm 22 rotates toward the direction away from the first connecting arm 21, the second connecting arm 22 is sleeved on one end of the transmission shaft 20 and moves downward along the height direction of the vehicle. As a result, under the driving action of the driving mechanism 3, the second connecting arm 22 drives the wheel 200 to move up and down, so as to achieve the effect of adjusting the relative position of the wheel 200 relative to the vehicle body, thereby achieving the effect of the suspension structure 100 actively adjusting the height of the vehicle body.

[0061] For example, when the driving mechanism 3 drives the second connecting arm 22 to rotate toward the direction close to the first connecting arm 21, the wheel 200 and the vehicle body are close to each other in the height direction of the vehicle, that is, the height of the vehicle body is reduced, and the ground clearance of the vehicle is reduced. When the driving mechanism 3 drives the second connecting arm 22 to rotate toward the direction away from the first connecting arm 21, the wheel 200 and the vehicle body are away from each other in the height direction of the vehicle, that is, the height of the vehicle body is increased, and the ground clearance of the vehicle is increased. In this way, the suspension structure 100 has the effect of actively adjusting the height of the vehicle body, and the effect of changing the size of the ground clearance of the vehicle is achieved.

[0062] In addition, when the wheel 200 encounters a bump on the ground during driving, the wheel 200 drives the second connecting arm 22 to rotate in the direction close to the first connecting arm 21, but under the action of gravity, the wheel 200 has a tendency to move downward, and the second connecting arm 22 has a tendency to rotate in the direction away from the first connecting arm 21. Therefore, when the wheel 200 encounters a bump on the ground, the driving mechanism 3 drives the second connecting arm 22 to rotate in the direction close to the first connecting arm 21, offsetting the tendency of the second connecting arm 22 to rotate in the direction away from the first connecting arm 21 under the action of gravity, achieving the effect of the second connecting arm 22 driving the wheel 200 to move upward, thereby reducing the tendency of the vehicle body to move upward due to the bump, thereby achieving the effect of reducing the vibration of the vehicle, and improving the driving comfort and stability of the vehicle.

[0063] During the driving process of the vehicle, when the wheel 200 encounters a pothole on the ground, there is a certain gap between the wheel 200 and the ground. Under the driving action of the driving mechanism 3, the driving mechanism 3 drives the second connecting arm 22 to rotate in the direction away from the first connecting arm 21, that is, the second connecting arm 22 drives the wheel 200 to move downward, so that the wheel 200 quickly contacts the ground, and the suspension structure 100 is supported between the wheel 200 and the vehicle body, thereby suppressing the tendency of the vehicle body to move downward due to the pothole, thereby achieving the effect of reducing the vibration of the vehicle and improving the driving comfort and stability of the vehicle.

[0064] Therefore, according to the suspension structure 100 of the embodiment of the present invention, the suspension structure 100 can actively adjust the height of the vehicle body, achieve the effect of changing the ground clearance of the vehicle, and reduce the tendency of the vehicle body to move upward due to the ground, and suppress the tendency of the vehicle body to move downward due to the ground, thereby achieving the vibration reduction effect of the suspension structure 100, which is beneficial to improving the driving comfort and stability of the vehicle. In addition, the suspension structure 100 has a simple and compact structure and a small volume, so that the space used to arrange the suspension structure 100 is small, which is beneficial to the space arrangement of the vehicle and improves the utilization of the vehicle space.

[0065] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the suspension structure 100 may also include: a first connecting shaft 11 and a second connecting shaft 12, both of which are suitable for being fixedly connected to the vehicle body, a first connecting arm 21 being connected between the first connecting shaft 11 and the second connecting shaft 12, and one end of the second connecting arm 22 being rotatably connected to the second connecting shaft 12 so that the second connecting arm 22 rotates around the second connecting shaft 12, thereby achieving an effect of the second connecting arm 22 rotating relative to the first connecting arm 21.

[0066] One end of the first connecting arm 21 is connected to the first connecting shaft 11, and the other end of the first connecting arm 21 is connected to the second connecting shaft 12, so that the first connecting arm 21 is connected between the first connecting shaft 11 and the second connecting shaft 12, and the first connecting shaft 11 and the second connecting shaft 12 are both suitable for being fixedly connected to the vehicle body, thereby limiting the relative position of the first connecting arm 21 and the vehicle body, so as to achieve the effect of the first connecting arm 21 being fixedly assembled to the vehicle body, so that the first connecting arm 21 is stationary relative to the vehicle body.

[0067] And one end of the second connecting arm 22 is rotatably connected to the second connecting shaft 12, so that the second connecting arm 22 and the first connecting arm 21 are indirectly connected through the second connecting shaft 12, and the second connecting arm 22 and the first connecting arm 21 are rotatably connected.

[0068] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the other end of the second connecting arm 22 has a sleeve 2, and the sleeve 2 is suitable for being sleeved on the transmission shaft 20. Along the circumference of the transmission shaft 20, the transmission shaft 20 rotates relative to the sleeve 2, so that the transmission shaft 20 can be rotatably assembled on the sleeve 2, thereby achieving the effect of the transmission shaft 20 being rotatably assembled on the second connecting arm 22, so as to achieve the effect of the wheel 200 rolling.

[0069] In some embodiments of the present invention, Figure 2 As shown, the first connecting shaft 11, the second connecting shaft 12 and the sleeve 2 are parallel to each other. It can also be understood that the axis of the first connecting shaft 11, the axis of the second connecting shaft 12 and the axis of the sleeve 2 are parallel to each other. Such a configuration facilitates the assembly of various components of the suspension structure 100 and can ensure the working performance of the suspension structure 100 to avoid interference between the first connecting arm 21 and the second connecting arm 22 during the rotation of the second connecting arm 22 around the second connecting shaft 12 relative to the first connecting arm 21.

[0070] In some embodiments of the present invention, Figure 2 As shown, along the height direction of the vehicle, the second connecting shaft 12 is located between the first connecting shaft 11 and the sleeve 2, so as to achieve the effect that the second connecting arm 22 is connected between the first connecting arm 21 and the sleeve 2, and to achieve the effect that the second connecting arm 22 rotates around the second connecting shaft 12 relative to the first connecting arm 21, so that the second connecting arm 22 has a rotation tendency toward the direction approaching the first connecting arm 21, and the second connecting arm 22 has a rotation tendency toward the direction away from the first connecting arm 21, and the sleeve 2 moves with the second connecting arm 22 relative to the first connecting arm 21, so as to achieve the effect of the wheel 200 moving up and down, which is beneficial to realize that the suspension structure 100 has the effect of actively adjusting the height of the vehicle body.

[0071] In some embodiments of the present invention, the second connecting shaft 12 has a first shaft body and a second shaft body. The first shaft body can be fixedly connected to the vehicle body, the second shaft body is sleeved on the first shaft body and can rotate relative to the first shaft body, the first shaft body is fixedly connected to the first connecting arm 21, and the second shaft body is fixedly connected to the second connecting arm 22, thereby achieving the effect of the second connecting arm 22 rotating around the second connecting shaft 12 relative to the first connecting arm 21.

[0072] In some embodiments of the present invention, a ball bearing may be provided between the first shaft body and the second shaft body to achieve the effect that the second shaft body is sleeved on the first shaft body and can rotate relative to the first shaft body. The first connecting arm 21 is suitable for being fixedly connected to both ends of the first shaft body, and the first connecting arm 21 is suitable for avoiding the second shaft body, and the second connecting arm 22 is suitable for being fixedly connected to the outer peripheral wall of the second shaft body, thereby avoiding interference between the first shaft body and the second shaft body, so as to achieve the effect that the second connecting arm 22 rotates around the second connecting shaft 12.

[0073] In some embodiments of the present invention, Figure 2 As shown, the first connecting arm 21 is fixedly connected to the first connecting shaft 11 so that the first connecting arm 21 cannot rotate relative to the first connecting shaft 11, thereby limiting the relative position of the first connecting arm 21 and the first connecting shaft 11, and further achieving the effect of limiting the relative position of the first connecting arm 21 and the vehicle body, so as to achieve the effect of the first connecting arm 21 being stationary relative to the vehicle body.

[0074] In some embodiments of the present invention, welding or bolting or other fixing methods can be used to fix the first connecting arm 21 to the first connecting shaft 11. The embodiments of the present invention fix the first connecting arm 21 and the first connecting shaft 11 by welding, which is beneficial to improve the connection strength between the first connecting arm 21 and the first connecting shaft 11 and reduce the risk of separation of the first connecting arm 21 and the first connecting shaft 11, thereby improving the connection reliability between the first connecting arm 21 and the first connecting shaft 11, and further reducing the risk of failure of the suspension structure 100.

[0075] In some embodiments of the present invention, Figure 2 As shown, the second connecting arm 22 is fixedly connected to the sleeve 2 so that the second connecting arm 22 cannot rotate relative to the sleeve 2, thereby limiting the relative position of the second connecting arm 22 and the sleeve 2, so that under the action of the wheel 200, the wheel 200 can drive the second connecting arm 22 to rotate, and under the driving action of the driving mechanism 3, the second connecting arm 22 can drive the wheel 200 to move up and down, thereby achieving the vibration reduction effect of the suspension structure 100 and the effect that the suspension structure 100 can actively adjust the height of the vehicle body.

[0076] In some embodiments of the present invention, welding or bolting or other fixing methods can be used to fix the second connecting arm 22 and the sleeve 2. The embodiments of the present invention fix the second connecting arm 22 and the sleeve 2 by welding, which is beneficial to improve the connection strength between the second connecting arm 22 and the sleeve 2 and reduce the risk of separation of the second connecting arm 22 and the sleeve 2, thereby improving the connection reliability between the second connecting arm 22 and the sleeve 2, and further reducing the risk of failure of the suspension structure 100.

[0077] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the first connecting shaft 11 and the second connecting shaft 12 both have a connecting portion 1, which is suitable for fixed connection with the vehicle body, so as to achieve the effect that the first connecting shaft 11 and the second connecting shaft 12 are both fixedly connected to the vehicle body, thereby achieving the effect that the suspension structure 100 is fixedly assembled to the vehicle body.

[0078] Specifically, the first shaft body of the second connecting shaft 12 can be provided with a connecting portion 1, the connecting portion 1 can have a connecting piece 10, and the vehicle body can have a matching piece adapted to the connecting piece 10. The connecting piece 10 and the matching piece are fixed together to achieve the effect of fixed connection between the connecting portion 1 and the vehicle body, thereby achieving the effect of fixed connection between the first connecting shaft 11 and the second connecting shaft 12 and the vehicle body.

[0079] In some embodiments of the present invention, the connecting portion 1 may have multiple connecting parts 10, and the vehicle body may have multiple matching parts. The multiple connecting parts 10 are respectively matched with the multiple matching parts in a one-to-one manner. By assembling the multiple connecting parts 1 with the multiple matching parts, the connection strength between the connecting portion 1 and the vehicle body is improved, thereby reducing the risk of separation of the first connecting shaft 11 from the vehicle body and reducing the risk of separation of the second connecting shaft 12 from the vehicle body, so as to achieve the effect of reliably assembling and fixing the suspension structure 100 to the vehicle body, thereby reducing the risk of separation of the suspension structure 100 from the vehicle body.

[0080] In some embodiments of the present invention, the connecting member 10 can be constructed as a screw, and the matching member can be constructed as a screw hole. The screw is suitable for threaded cooperation with the screw hole to achieve the effect of fixed cooperation between the connecting member 10 and the matching member, thereby achieving the effect of fixed connection between the connecting part 1 and the vehicle body.

[0081] In other embodiments of the present invention, the connecting member 10 may also be configured as a welding rib, and the matching member may also be configured as a welding groove. During the process of the connecting member 10 and the matching member being matched and fixed, the welding rib may be placed in the welding groove to achieve the effect of the matching assembly of the connecting member 10 and the matching member, and the welding rib may be welded in the welding groove by a welding device, thereby achieving the effect of the fixed matching of the connecting member 10 and the matching member. Thus, the effect of the first connecting shaft 11 and the second connecting shaft 12 being fixedly connected to the vehicle body is achieved.

[0082] In some embodiments of the present invention, Figure 1 As shown, the present invention is explained by taking the example that the connecting member 10 is constructed as a screw rod and the matching member is constructed as a screw hole. By threading the screw rod and the screw hole together, the effect of the connecting part 1 being detachably installed on the vehicle body is achieved, so that the first connecting shaft 11 and the second connecting shaft 12 can both be detachably installed on the vehicle body, thereby achieving the effect of the suspension structure 100 being detachably installed on the vehicle body.

[0083] In some embodiments of the present invention, Figure 2 As shown, the first connecting arm 21 is fixed with a first connecting seat 41, the second connecting arm 22 is fixed with a second connecting seat 42, the driving mechanism 3 is connected between the first connecting seat 41 and the second connecting seat 42 and is suitable for driving the second connecting arm 22 to rotate around the second connecting axis 12, thereby achieving the effect of the driving mechanism 3 driving the second connecting arm 22 to rotate.

[0084] Along the height direction of the vehicle, the first connection seat 41 and the second connection seat 42 are both located between the first connection arm 21 and the second connection arm 22. One end of the first connection seat 41 is fixedly connected to the first connection arm 21, so that the first connection seat 41 is fixedly arranged on the first connection arm 21. One end of the second connection seat 42 is fixedly connected to the second connection arm 22, so that the second connection seat 42 is fixedly arranged on the second connection arm 22. The other end of the first connection seat 41 is connected to one end of the driving mechanism 3 to achieve the effect of connecting the driving mechanism 3 with the first connection arm 21. The other end of the second connection seat 42 is connected to the other end of the driving mechanism 3 to achieve the effect of connecting the driving mechanism 3 with the second connection arm 22. Thus, the effect of connecting the driving mechanism 3 between the first connection seat 41 and the second connection seat 42 is achieved, and then the effect of connecting the driving mechanism 3 between the first connection arm 21 and the second connection arm 22 is achieved. In addition, since the second connection arm 22 is suitable for rotating around the second connection shaft 12, the second connection arm 22 has a tendency to rotate around the second connection shaft 12 under the driving action of the driving mechanism 3.

[0085] In some embodiments of the present invention, the driving mechanism 3 has a driving body and a driving rod, which are connected to drive the driving rod to extend and retract. The driving body is connected to one of the first connecting arm 21 and the second connecting arm 22, and the driving rod is connected to the other of the first connecting arm 21 and the second connecting arm 22. The driving rod is extended and retracted to achieve the effect of lengthening and shortening the driving mechanism 3, thereby achieving the effect of changing the stroke of the driving mechanism 3, so that the driving mechanism 3 is used to drive the second connecting arm 22 to rotate.

[0086] In some embodiments of the present invention, the driving rod is movably arranged in the driving body, and along the height direction of the vehicle, the driving rod is suitable for moving relative to the driving body, so as to achieve the effect that the driving body drives the driving rod to extend and retract. When the driving rod moves in a direction away from the driving body, the driving mechanism 3 extends, so that the driving mechanism 3 drives the second connecting arm 22 to rotate in a direction away from the first connecting arm 21. When the driving rod moves in a direction close to the driving body, the driving mechanism 3 shortens, so that the driving mechanism 3 drives the second connecting arm 22 to rotate in a direction close to the first connecting arm 21, thereby achieving the effect that the suspension structure 100 has the active adjustment of the vehicle body height. In some embodiments of the present invention, the example in which the driving body is connected to the second connecting seat 42 and the driving rod is connected to the first connecting seat 41 is used for explanation.

[0087] In some embodiments of the present invention, Figure 2 As shown, the driving mechanism 3 is movably connected to at least one of the first connecting seat 41 and the second connecting seat 42, so that when the driving mechanism 3 drives the second connecting arm 22 to rotate relative to the first connecting arm 21, the driving mechanism 3 is prevented from interfering with the first connecting seat 41 and the second connecting seat 42, thereby ensuring that the second connecting arm 22 can rotate relative to the first connecting arm 21. In some embodiments of the present invention, the driving rod is movably connected to the first connecting seat 41, and the driving body is movably connected to the second connecting seat 42.

[0088] In some embodiments of the present invention, Figure 3 As shown, the first connecting seat 41 has a first rotating shaft 41a, which is suitable for rotating around its own axis. The first rotating shaft 41a is connected to the driving rod, thereby achieving the effect of active connection between the driving rod and the first connecting seat 41, avoiding interference between the driving rod and the first connecting seat 41, and ensuring that the driving mechanism 3 can drive the second connecting arm 22 to rotate.

[0089] In some embodiments, the driving rod may have a first assembly hole, and the first rotating shaft 41a is suitable for being inserted into the first assembly hole to achieve the effect of connecting the first rotating shaft 41a with the driving rod, and since the first rotating shaft 41a is suitable for rotating around its own axis, the driving rod is suitable for rotating with the first rotating shaft 41a relative to the first connecting seat 41, thereby achieving the effect of active connection between the driving rod and the first connecting seat 41, so as to avoid interference between the driving rod and the first connecting seat 41 during the extension and retraction of the driving mechanism 3, and ensure that the driving mechanism 3 drives the second connecting arm 22 to rotate relative to the first connecting arm 21.

[0090] In some embodiments of the present invention, Figure 3As shown, the first connecting seat 41 has a first matching hole 41b. Along the height direction of the vehicle, the first matching hole 41b is constructed as a through hole that penetrates the first connecting seat 41. During the matching and assembly process of the driving rod and the first rotating shaft 41a, the driving rod is suitable for extending into the first matching hole 41b and matching and assembling with the first rotating shaft 41a. At the same time, the first matching hole 41b is used to avoid the driving rod, avoid interference between the first connecting seat 41 and the driving rod, so as to achieve the effect of active connection between the driving rod and the first connecting seat 41.

[0091] In some embodiments of the present invention, the second connection seat 42 has a second rotation axis, which is suitable for rotating around its own axis and connected to the driving body, so as to achieve the effect of active connection between the driving body and the second connection seat 42, avoid interference between the driving body and the second connection seat 42, and ensure that the driving mechanism 3 drives the second connection arm 22 to rotate relative to the first connection arm 21.

[0092] In some embodiments, the driving body may have a second assembly hole, and the second rotating shaft is suitable for being inserted into the second assembly hole to achieve the effect of connecting the second rotating shaft with the driving body, and because the second rotating shaft is suitable for rotating around its own axis, the driving body is suitable for rotating with the second rotating shaft relative to the second connecting seat 42, thereby achieving the effect of active connection between the driving body and the second connecting seat 42, so as to avoid interference between the driving body and the second connecting seat 42 during the extension and retraction of the power driving member 31, and ensure that the driving mechanism 3 drives the second connecting arm 22 to rotate.

[0093] In some embodiments of the present invention, Figure 2 As shown, the connection position between the driving mechanism 3 and the first connecting arm 21 is located between the two ends of the first connecting arm 21, and the connection position between the driving mechanism 3 and the second connecting arm 22 is located between the two ends of the second connecting arm 22. By changing the connection position between the driving mechanism 3 and the first connecting arm 21 and the connection position between the driving mechanism 3 and the second connecting arm 22, the effect of changing the motion stroke of the suspension structure 100 can be achieved. It should be noted that, as Figure 2 As shown, the first connecting seat 41 and the second connecting seat 42 can be set according to needs, specifically setting the first connecting seat 41 at the position of the first connecting arm 21, and specifically setting the second connecting seat 42 at the position of the second connecting arm 22, so as to achieve the effect of specifically setting the connection position between the driving mechanism 3 and the first connecting arm 21 and the second connecting arm 22.

[0094] The closer the first connecting seat 41 and the second connecting seat 42 are to the second connecting shaft 12, the closer the driving mechanism 3 is to the second connecting shaft 12, so that the movement stroke of the suspension structure 100 is greater, and the range in which the suspension structure 100 can adjust the vehicle body height is larger. Therefore, by changing the connection position between the driving mechanism 3 and the first connecting arm 21 and the connection position between the driving mechanism 3 and the second connecting arm 22, the effect of changing the movement stroke of the suspension structure 100 can be achieved.

[0095] In some embodiments of the present invention, Figure 2 and Figure 3 As shown, the suspension structure 100 may further include: an elastic buffer 32, which absorbs energy through elastic deformation, thereby achieving the effect of energy absorption and vibration reduction of the drive mechanism 3. The elastic buffer 32 is sleeved on the drive mechanism 3, and the two ends of the elastic buffer 32 are respectively fixed to the first connecting seat 41 and the second connecting seat 42, that is, the elastic buffer 32 is elastically supported between the first connecting arm 21 and the second connecting arm 22, and the elastic buffer 32, the first connecting arm 21 and the second connecting arm 22 constitute a vibration reduction structure, which is conducive to improving the vibration reduction effect of the suspension structure 100.

[0096] The elastic buffer 32 can be constructed as an elastic buffer 32 such as a coil spring or elastic rubber. The present application takes the elastic buffer 32 constructed as a coil spring as an example, so that the elastic buffer 32 is suitable for being mounted on the outside of the driving mechanism 3, thereby achieving a compact structure and small volume of the suspension structure 100, which is beneficial to reducing the volume of the suspension structure 100.

[0097] During the driving process of the vehicle, when the wheel 200 jumps up, the wheel 200 drives the second connecting arm 22 to rotate in the direction close to the first connecting arm 21, and the two ends of the elastic buffer 32 are squeezed by the first connecting seat 41 and the second connecting seat 42 respectively. The elastic buffer 32 elastically deforms to absorb the force of the wheel 200 on the first connecting arm 21, thereby reducing the tendency of the vehicle body to move upward due to the jumping of the wheel 200, thereby achieving the effect of reducing the vibration of the vehicle and improving the driving comfort and stability of the vehicle.

[0098] In addition, the elastic buffer 32 is elastically supported between the first connecting arm 21 and the second connecting arm 22, so as to prevent the first connecting arm 21 and the second connecting arm 22 from causing excessive compression and stretching to the driving mechanism 3, which is beneficial to prolonging the service life of the driving mechanism 3. At the same time, it is beneficial to improve the load-bearing capacity of the suspension structure 100, so that the suspension structure 100 can bear the weight of the vehicle body, and reduce the risk of deformation of the suspension structure 100.

[0099] In some embodiments of the present invention, Figure 3As shown, one end of the elastic buffer 32 is connected to the first connecting seat 41 through the first tray 51, and the other end of the elastic buffer 32 is connected to the second connecting seat 42 through the second tray 52, thereby achieving the effect that the two ends of the elastic buffer 32 are respectively fixed to the first connecting seat 41 and the second connecting seat 42, and since the first connecting seat 41 is fixedly connected to the first connecting arm 21, and the second connecting seat 42 is fixedly connected to the second connecting arm 22, the effect that the driving mechanism 3 is elastically supported between the first connecting arm 21 and the second connecting arm 22 is achieved.

[0100] In some embodiments of the present invention, the two ends of the elastic buffer 32 are respectively fixedly connected to the first tray 51 and the second tray 52, and the end of the elastic buffer 32 connected to the first tray 51 has a first assembly portion, the first tray 51 has a first matching portion, and the first assembly portion is assembled with the first matching portion, thereby achieving the effect of the elastic buffer 32 being fixedly connected to the first tray 51. The end of the elastic buffer 32 connected to the second tray 52 has a second assembly portion, the second tray 52 has a second matching portion, and the second assembly portion is assembled with the second matching portion, thereby achieving the effect of the elastic buffer 32 being fixedly connected to the second tray 52, thereby, the first tray 51 and the second tray 52 can limit the relative position of the elastic buffer 32 relative to the first connecting seat 41 and the second connecting seat 42, so that the elastic buffer 32 is reliably set between the first connecting seat 41 and the second connecting seat 42, thereby improving the reliability of the suspension structure 100.

[0101] In some embodiments of the present invention, the first assembly portion and the second assembly portion can both be constructed as screws, and the first matching portion and the second matching portion can both be constructed as screw holes, so that the first assembly portion and the first matching portion are screwed together, and the second assembly portion and the second matching portion are screwed together, thereby achieving the effect of fixing the first pallet 51 and the second pallet 52 at both ends of the elastic buffer 32.

[0102] In some embodiments of the present invention, the driving mechanism 3 can be a linear motor, the driving body is constructed as a motor of the linear motor, the driving rod is constructed as a push rod of the linear motor, and the motor is used to drive the push rod to extend and retract, thereby achieving the effect of extending and retracting the linear motor, so that the output of the driving mechanism 3 is a linear motion.

[0103] The linear motor has the advantages of high sensitivity and small hysteresis effect, which is beneficial to improving the vibration reduction effect of the suspension structure 100. At the same time, the linear motor can simulate the damping force and stabilizer bar force of the traditional suspension. Therefore, according to the suspension structure 100 of the present application, the damper, stabilizer bar and stabilizer bar pull rod can be eliminated to make the suspension structure 100 compact and small in size, and reduce the vehicle manufacturing cost while obtaining better shock absorption effect.

[0104] In other embodiments of the present invention, the driving mechanism 3 can be a pneumatic component, the driving body is configured as a cylinder of the pneumatic component, the driving rod is configured as a pneumatic pull rod of the pneumatic component, and the cylinder is used to drive the pneumatic pull rod to extend and retract, thereby achieving the effect of the pneumatic component extending and retracting. In some embodiments, the driving mechanism 3 can also be a combination of a rotary motor and a transmission mechanism, which has realized a linear motion mechanism.

[0105] In some embodiments of the present invention, the vehicle has a vehicle height sensor and a CPU (central processing unit). The vehicle height sensor is used to monitor changes in the vehicle height, and the CPU is connected to both the vehicle height sensor and the drive mechanism 3. The vehicle height sensor transmits the detected vehicle height change signal to the CPU, and the CPU is used to process and analyze the vehicle height change signal and control the operation of the drive mechanism 3 to achieve the effect of actively adjusting the vehicle height of the suspension structure 100.

[0106] For example, when the vehicle is traveling on a bumpy road, the wheel 200 will move up and down with the ups and downs of the road surface. When the wheel 200 moves upward, the transmission shaft 20 will drive the sleeve 2 to move upward, so that the second connecting arm 22 rotates around the second connecting shaft 12 in the direction close to the first connecting arm 21. The vehicle height sensor transmits the vehicle height change signal to the CPU, and the CPU analyzes and processes the vehicle height change signal. The CPU controls the drive mechanism 3 to work according to the change in vehicle height. At this time, the CPU controls the drive mechanism 3 to shorten (that is, the drive rod moves in the direction close to the driving body), offsetting the rotation tendency of the second connecting arm 22 in the direction away from the first connecting arm 21 under the action of gravity, and achieving the effect of the second connecting arm 22 driving the wheel 200 to move upward, thereby reducing the tendency of the protrusion to cause the vehicle body to move upward, thereby achieving the effect of reducing the vibration of the vehicle, thereby improving the driving comfort and stability of the vehicle.

[0107] When the wheel 200 encounters a pothole, the wheel 200 moves downward under the action of gravity and the elastic buffer 32, and the vehicle height sensor transmits the vehicle height change signal to the CPU. The CPU analyzes and processes the vehicle height change signal, and the CPU controls the drive mechanism 3 to work according to the change in the vehicle height. At this time, the CPU controls the drive mechanism to extend (that is, the drive rod moves in the direction away from the drive body) so that the drive mechanism 3 drives the second connecting arm 22 to rotate in the direction away from the first connecting arm 21, that is, the second connecting arm 22 drives the wheel 200 to move downward, so that the wheel 200 quickly contacts the ground, and the suspension structure 100 is supported between the wheel 200 and the vehicle body, thereby suppressing the tendency of the ground to cause the vehicle body to move downward, thereby achieving the effect of reducing the vibration of the vehicle and improving the driving comfort and stability of the vehicle.

[0108] In some embodiments of the present invention, Figure 1As shown, the suspension structure 100 may further include: a protective cover 6, which is arranged on the outside of the first connecting arm 21, the second connecting arm 22 and the driving mechanism 3, and the first connecting shaft 11 and the second connecting shaft 12 are both installed on the protective cover 6, so as to prevent foreign objects such as stones and soil from adhering to the first connecting arm 21, the second connecting arm 22 and the driving mechanism 3, thereby improving the reliability of the suspension structure 100.

[0109] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, the protective cover 6 defines an assembly space 60, and the first connecting arm 21, the second connecting arm 22 and the driving mechanism 3 are all arranged in the assembly space 60, so that the protective cover 6 is arranged on the outside of the first connecting arm 21, the second connecting arm 22 and the driving mechanism 3, so that the protective cover 6 is used to block foreign objects such as stones and soil, thereby preventing foreign objects from adhering to the first connecting arm 21, the second connecting arm 22 and the driving mechanism 3, and improving the reliability of the suspension structure 100.

[0110] In some embodiments of the present invention, Figure 4 As shown, the protective cover 6 may have a first side wall 61 and a second side wall 62 opposite to each other, the first side wall 61 and the second side wall 62 are opposite to each other and spaced apart, the first connecting arm 21, the second connecting arm 22 and the driving mechanism 3 are located between the first side wall 61 and the second side wall 62, the inner wall surface of the first side wall 61 is provided with a first magnet 71, the inner wall surface of the second side wall 62 is provided with a second magnet 72, the second connecting arm 22 is a conductor, the magnetic pole direction of the first magnet 71 and the magnetic pole direction of the second magnet 72 are oppositely arranged, so as to form a magnetic field direction roughly from the first side wall 61 to the second side wall 62 or the magnetic field direction is roughly from the second side wall 62 to the first side wall 61. For example, the first magnet 71 and the second magnet 72 are both permanent magnets, and the side of the first magnet 71 close to the second magnet 72 is the N pole, and the side of the second magnet 72 close to the first magnet 71 is the S pole. At this time, the magnetic field direction is roughly from the first magnet 71 to the second magnet 72. It can also be that the side of the first magnet 71 close to the second magnet 72 is the S pole, and the side of the second magnet 72 close to the first magnet 71 is the N pole. At this time, the magnetic field direction is roughly from the second magnet 72 to the first magnet 71.

[0111] Since the second connecting arm 22 rotates relative to the first connecting arm 21, the second connecting arm 22 moves in the assembly space 60, that is, the second connecting arm 22 is suitable for cutting the magnetic flux lines between the first magnet 71 and the second magnet 72, so that in the process of the second connecting arm 22 rotating relative to the first connecting arm 21, the second connecting arm 22 cuts the magnetic flux lines to generate electricity, thereby achieving the effect of the suspension structure 100 generating electrical energy.

[0112] Specifically, the second connecting arm 22 can be made of a conductive material, such as a metal material such as steel or iron, so that the second connecting arm 22 can be constructed as a conductor, and the second connecting arm 22 is suitable for being electrically connected to the energy storage device of the vehicle, so that when the second connecting arm 22 rotates to cut the magnetic flux lines, the second connecting arm 22 generates a current, and the generated current is converted into electric energy and stored in the energy storage device, thereby achieving the effect of the suspension structure 100 generating electric energy and storing the electric energy in the energy storage device, and further achieving the effect of the suspension structure 100 replenishing electric energy for the energy storage device. The electric energy of the energy storage device is used to provide electric energy for the vehicle to travel, and is used for the drive mechanism 3 to drive the second connecting arm 22 to rotate around the second connecting shaft 12, thereby helping to reduce the energy consumption of the vehicle, and further helping to increase the cruising range of the vehicle.

[0113] For example, during the driving of the vehicle, the wheel 200 is always in a state of varying degrees of vibration. When the wheel 200 vibrates, it will drive the second connecting arm 22 to rotate around the second connecting axis 12. At this time, the second connecting arm 22 cuts the magnetic flux lines generated between the first magnet 71 and the second magnet 72, and generates current on the second connecting arm 22. The current generated by the second connecting arm 22 can be converted into stable electrical energy through an inverter and stored in an energy storage device, which is beneficial to increase the vehicle's cruising range.

[0114] In some embodiments of the present invention, Figure 4 As shown, there are multiple first magnets 71 and multiple second magnets 72, and the multiple first magnets 71 and the multiple second magnets 72 correspond one to one. The magnetic flux lines generated between the corresponding first magnets 71 and the second magnets 72 are increased by setting the first magnets 71 and the second magnets 72 to increase the number of magnetic flux lines cut by the second connecting arm 22 during the rotation of the second connecting arm 22 around the second connecting axis 12, so that a larger current is generated on the second connecting arm 22, so that more electric energy is stored in the energy storage device, thereby further increasing the vehicle's cruising range.

[0115] Specifically, Figure 4 As shown, a plurality of first magnets 71 are sequentially spaced apart on the first side wall 61 along the height direction of the suspension structure 100, and a plurality of second magnets 72 are sequentially spaced apart on the second side wall 62 along the height direction of the suspension structure 100, and the plurality of first magnets 71 and the plurality of second magnets 72 correspond one-to-one to generate magnetic flux lines, thereby increasing the number of magnetic flux lines cut by the second connecting arm 22, so that a larger current is generated on the second connecting arm 22, and more electric energy is stored in the energy storage device, thereby further increasing the vehicle's cruising range.

[0116] In some embodiments of the present invention, Figure 4As shown, the first side wall 61 and / or the second side wall 62 is provided with a first mounting hole 63, and the first connecting shaft 11 is passed through the first mounting hole 63, so that the first connecting shaft 11 is suitable for extending into the assembly space 60, thereby facilitating the first connecting arm 21 to be arranged in the assembly space 60, so that the protective cover 6 is arranged on the outside of the first connecting arm 21, thereby reducing the risk of foreign matter adhering to the first connecting arm 21 and improving the reliability of the suspension structure 100.

[0117] In some embodiments of the present invention, Figure 4 As shown, the present invention takes the example that both the first side wall 61 and the second side wall 62 are provided with a first mounting hole 63, so that the first connecting shaft 11 is passed through the first side wall 61 and the second side wall 62, and the first connecting shaft 11 is fixed to the first side wall 61 and the second side wall 62, thereby achieving the effect of fixed connection between the protective cover 6 and the first connecting shaft 11, and reducing the risk of separation of the protective cover 6 and the first connecting shaft 11.

[0118] In some embodiments of the present invention, Figure 4 As shown, the first side wall 61 and / or the second side wall 62 is provided with a second mounting hole 64, and the second connecting shaft 12 is passed through the second mounting hole 64, so that the second connecting shaft 12 is suitable for extending into the assembly space 60, thereby facilitating the second connecting arm 22 to be arranged in the assembly space 60, so that the protective cover 6 is arranged on the outside of the second connecting arm 22, and at the same time facilitating the driving mechanism 3 to be arranged in the assembly space 60, so that the protective cover 6 is arranged on the outside of the driving mechanism 3, thereby reducing the risk of foreign matter adhering to the second connecting arm 22 and the driving mechanism 3, and improving the reliability of the suspension structure 100.

[0119] In some embodiments of the present invention, Figure 4 As shown, the present invention takes the example that both the first side wall 61 and the second side wall 62 are provided with a second mounting hole 64, so that the second connecting shaft 12 is passed through the first side wall 61 and the second side wall 62, and the second connecting shaft 12 is fixed to the first side wall 61 and the second side wall 62, thereby achieving the effect of fixed connection between the protective cover 6 and the second connecting shaft 12, and reducing the risk of separation of the protective cover 6 and the second connecting shaft 12.
