As shown in fig. 1 and 2, a suspension structure 100 according to an embodiment of the present invention includes a first connection arm 21, a second connection arm 22, and a driving mechanism 3. The first connecting arm 21 is suitable for being connected with the automobile body of vehicle, the one end and the first connecting arm 21 rotation of second connecting arm 22 are connected, the other end of second connecting arm 22 is suitable for being connected with the wheel, actuating mechanism 3 connects between first connecting arm 21 and second connecting arm 22, actuating mechanism 3 can drive the relative first connecting arm 21 rotation of second connecting arm 22, with the distance of adjusting the plane that the tie point of first connecting arm 21 and automobile body is located to the tie point of second connecting arm 22 and wheel is located, with the effect of realizing suspension structure 100 damping and changing the automobile body height, thereby be favorable to promoting travelling comfort and the stability of vehicle, be favorable to increasing the motion stroke of suspension structure 100 simultaneously, increase suspension structure 100 and adjust the scope of automobile body height, and then be favorable to promoting suspension structure 100's damping effect. And the suspension structure 100 has simple and compact structure and smaller volume, so that the space for arranging the suspension structure 100 is smaller, the space arrangement of the vehicle is facilitated, and the utilization of the vehicle space is improved.

According to the suspension structure 100 disclosed by the 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 for driving the stroke of the second connecting arm 22 relative to the rotation of the first connecting arm 21, the distance from the plane of the connecting point of the first connecting arm 21 and the vehicle body to the plane of the connecting point of the second connecting arm 21 and the vehicle wheel 200 is enlarged, so that the stroke requirement of the driving mechanism 3 is smaller, the function of adjusting the height of the vehicle body can be realized by the smaller driving mechanism 3, the size of the driving mechanism 3 in the height direction of the vehicle is greatly reduced, the weight of the driving mechanism 3 is greatly reduced, the weight of the suspension structure 100 is reduced, the suspension structure 100 is simple and compact, the size is smaller, the space for arranging the suspension structure 100 is smaller, the space arrangement of the vehicle is facilitated, and the space utilization of the vehicle is improved.

In some embodiments of the present invention, the transmission shaft 20 is in driving connection with the wheel 200 of the vehicle, and the other end of the second connecting arm 22 is sleeved on the outer side of the transmission shaft 20, and the transmission shaft 20 rotates relative to the second connecting arm 22 along the circumferential direction of the transmission shaft 20, so as to achieve the effect that the transmission shaft 20 is rotatably assembled on the second connecting arm 22, and further facilitate the rolling effect of the wheel 200.

Both ends of the first connecting arm 21 are fixedly connected with the vehicle body, so that the relative position of the first connecting arm 21 and the vehicle body is limited, i.e., the first connecting arm 21 is stationary relative to the vehicle body.

The second connecting arm 22 is rotatably connected with the first connecting arm 21, and when the wheel 200 moves up and down, the second connecting arm 22 rotates relative to the first connecting arm 21, so that the distance between the second connecting arm 22 and the first connecting arm 21 is increased or decreased, and one end of the transmission shaft 20 sleeved with the second connecting arm 22 moves along the height direction of the suspension structure 100, thereby realizing the effect of moving the wheel 200 up and down.

And, when the vehicle is mountain bike or commodity circulation, can be fixed in the outside of automobile body through the both ends of first linking arm 21 and suspension structure 100, avoid suspension structure 100 to occupy the passenger cabin space of vehicle, the arrangement in passenger cabin space is favorable, promotes passenger cabin space's availability.

The driving mechanism 3 is configured to drive the second connecting arm 22 to rotate relative to the first connecting arm 21, so that in a height direction of the vehicle, the second connecting arm 22 has a rotation tendency toward a direction approaching the first connecting arm 21, and the second connecting arm 22 has a rotation tendency toward a direction away from the first connecting arm 21, so as to achieve an effect that the second connecting arm 22 is sleeved on one end of the transmission shaft 20 to move up and down in the height direction of the vehicle, that is, when the second connecting arm 22 rotates toward the direction approaching the first connecting arm 21, the second connecting arm 22 is sleeved on one end of the transmission shaft 20 to move up in 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 to move down in the height direction of the vehicle. Therefore, the second connecting arm 22 drives the wheel 200 to move up and down under the driving action of the driving mechanism 3, so that the effect of adjusting the relative position of the wheel 200 relative to the vehicle body is achieved, and the effect of actively adjusting the vehicle body height of the suspension structure 100 is achieved.

For example, when the driving mechanism 3 drives the second link arm 22 to rotate in a direction approaching the first link arm 21, the wheels 200 and the vehicle body approach each other in the height direction of the vehicle, that is, the height of the vehicle body is lowered, and the ground clearance of the vehicle is reduced. When the driving mechanism 3 drives the second link arm 22 to rotate in a direction away from the first link arm 21, the wheels 200 and the vehicle body are separated 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. Thus, 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 are achieved by the suspension structure 100.

In addition, when the wheel 200 encounters a bulge of the ground during running of the vehicle, the wheel 200 drives the second link arm 22 to rotate in a direction approaching the first link arm 21, but the wheel 200 has a tendency to move downward by gravity, and the second link arm 22 has a tendency to rotate in a direction away from the first link arm 21. Therefore, when the wheel 200 encounters a bulge on the ground, the driving mechanism 3 drives the second connecting arm 22 to rotate towards the direction close to the first connecting arm 21, so that the rotation trend of the second connecting arm 22 towards the direction far away from the first connecting arm 21 under the action of gravity is counteracted, the effect that the wheel 200 is driven by the second connecting arm 22 to move upwards is achieved, the trend that the bulge causes the vehicle body to move upwards is reduced, the effect of reducing the vibration quantity of the vehicle is achieved, and the driving comfort and stability of the vehicle are improved.

In the running process of the vehicle, when the wheel 200 meets the pit on the ground, a certain gap exists 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 towards the direction away from the first connecting arm 21, namely, the second connecting arm 22 drives the wheel 200 to move downwards, so that the wheel 200 is rapidly contacted with the ground, the suspension structure 100 is supported between the wheel 200 and the vehicle body, the pit is restrained from causing the trend of the vehicle body to move downwards, the effect of reducing the vibration quantity of the vehicle is further achieved, and the running comfort and stability of the vehicle are improved.

Therefore, according to the suspension structure 100 of the embodiment of the invention, the suspension structure 100 can actively adjust the height of the vehicle body, thereby realizing the effect of changing the ground clearance of the vehicle, reducing the trend of the upward movement of the vehicle body caused by the ground and inhibiting the trend of the downward movement of the vehicle body caused by the ground, thereby realizing the vibration reduction effect of the suspension structure 100 and being beneficial to improving the driving comfort and stability of the vehicle.
