Technical Field

[0001] The invention relates to the technical field of steering handles, in particular to a steering handle with high-precision resetting. Background Art

[0002] In existing vehicles, most of them control the direction of the vehicle body through a steering wheel. However, since the steering wheel is large, it occupies a large volume on the vehicle body. For smaller vehicles, such as some small forklifts, the use of a steering wheel will cause inconvenience in operation and reduce the operator's space for movement. Therefore, steering control can be performed through a small steering handle.

[0003] In the prior art, the steering handle needs to be automatically reset by a reset member after being turned, and most of the existing steering handles use the same reset member as the steering wheel, that is, a reset structure such as a torsion spring structure is set in the vehicle body, but the existing reset structure is large in size, resulting in a large space occupied in the vehicle body and cannot be arranged in a small vehicle body. In addition, after the existing steering handle is automatically reset, it is often reset beyond the initial position for the first time due to the action of the reset force, which causes the steering handle to shake and the reset accuracy is poor.

[0006] A driving member is provided on the handle body, and a limiting member is provided on the inner side of the shell. The driving member and the limiting member are arranged in the shell along the vertical direction. The reset member includes an elastic member and two reset plates symmetrically arranged on both sides of the driving member and the limiting member. One end of the two reset plates can be rotatably connected to the hinge part, and the other ends of the two reset plates can be connected through the elastic member. The two sides of the limiting member can respectively fit with the inner sides of the two reset plates. The driving member can rotate with the handle body and can drive one of the reset plates to move toward the side away from the other reset plate.

[0007] According to the above-mentioned steering handle capable of achieving high-precision resetting, the driving member is configured as a driving column, which is fixed to the handle body and located directly below the hinged portion, and the two sides of the driving column can respectively fit with the inner sides of the two resetting plates.

[0008] According to the above-mentioned steering handle capable of achieving high-precision reset, the hinged portion is set as a first positioning hole, a second positioning hole is provided on one end of the two reset plates, the two second positioning holes are connected to the first positioning hole, a rotating shaft is provided in the connecting hole between the first positioning hole and the second positioning hole, and one end of the rotating shaft can be rotatably connected to the inner side of the shell.

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0023] like Figure 1-3 As shown, a steering handle capable of achieving high-precision resetting comprises a handle body 1, a shell 2 and a resetting member 3, wherein the handle body 1 is connected to a steering control unit of a vehicle body, and the steering of the vehicle body can be controlled by the steering control unit.

[0024] Specifically, the shell 2 is fixed on the vehicle body, and the handle body 1 includes a hinge part and two pressing parts 12 located on both sides of the hinge part. The handle body 1 is rotatably arranged in the shell 2 through the hinge part, and when the steering handle is in an initial non-steering position, the two pressing parts 12 are both extended to the outside of the shell 2. By pressing the two pressing parts 12, the handle body 1 can be driven to rotate around the hinge part, and the vehicle can be controlled to turn left or right according to the forward and reverse rotation of the handle body 1.

[0025] Among them, a driving member is provided on the handle body 1, and a limiting member is provided on the inner side of the shell 2. When in the initial position, the driving member and the limiting member are arranged in the shell 2 along the vertical direction. The reset member 3 includes an elastic member and two reset plates 32 symmetrically arranged on the driving member and on both sides of the driving member. One end of the two reset plates 32 can be rotatably connected to the hinge part, and the other ends of the two reset plates 32 can be connected through an elastic member. The two sides of the limiting member can be respectively fitted with the inner sides of the two reset plates 32. When the handle body 1 is driven to rotate by the pressing portion 12, the driving member can rotate with the handle body 1. Taking its rotation in the first direction as an example, the driving member The movable member can drive the reset plate 32 located on the side of the limit member facing the first direction to move toward the side away from the other reset plate 32, and the other reset plate 32 cannot rotate due to the limitation of the limit member. Therefore, the elastic member between the two reset plates 32 will be stretched, and there is an elastic force. After the applied external force is removed, the elastic member can drive the reset plate 32 that is initially rotating to reset, and the reset plate 32 drives the handle body 1 to reset through the driving member. After resetting to the initial position, the reset plate 32 is limited by the limit member and cannot pass through the limit member. Therefore, high-precision reset can be achieved to avoid shaking of the handle body 1.

[0026] Among them, the driving member is set to a driving column 13, which is fixed on the handle body 1. When the handle body 1 is in the initial position, the driving column 13 is located directly below the hinge part, and the two sides of the driving column 13 can be respectively fitted with the inner sides of the two reset plates 32, which is convenient for driving the two reset plates 32 to rotate in a direction away from each other.

[0027] In order to ensure that the rotation angle of the reset plate 32 is synchronized with that of the handle body 1, the hinge part is set as a first positioning hole 11, and a second positioning hole 321 is provided on one end of the two reset plates 32. The two second positioning holes 321 are connected to the first positioning hole 11, and a rotating shaft is provided in the connecting hole between the first positioning hole 11 and the second positioning hole 321. One end of the rotating shaft can be rotatably connected to the inner side of the shell 2. The handle body 1 can drive the rotating shaft to rotate, and the two reset plates 32 can rotate around the rotating shaft. Of course, they can also be driven by the driving column 13 to rotate with the rotating shaft. Since the center lines of their rotation are all on the same straight line, their rotation angles can be kept consistent, and the reset plates 32 can be driven to rotate synchronously.

[0028] In this embodiment, the steering control unit is connected to the rotating shaft, and the rotation angle of the rotating shaft is consistent with the rotation angle of the handle body 1 , so that the vehicle body can be controlled to steer in proportion to the rotation angle of the handle body 1 .

[0029] Specifically, the elastic member is configured as a reset spring 31, and the two ends of the reset spring 31 are respectively connected to one end of the two reset plates 32 away from the second positioning hole 321. When one reset plate 32 is driven to rotate by the driving column 13, the distance between the two reset plates 32 increases, which will stretch the reset spring 31. When the force applied by the operator is greater than the elastic force, the handle body 1 can be overcome to continue to rotate. When the operator no longer applies force to the handle body 1, the elastic force can be used as a reset force to drive it to reset.

[0030] In order to achieve quick positioning of the reset spring 31 and the reset plate 32, a positioning groove 322 is provided on the outer side of the reset plate 32 away from the second positioning hole 321, and hooks 311 are provided at both ends of the reset spring 31. The hooks 311 can be extended into the positioning groove 322 and buckled with the reset plate 32. That is, during installation, it is only necessary to directly hang the hooks 311 at both ends of the reset spring 31 into the positioning groove 322, which is simple and quick.

[0031] Specifically, the limiting member is configured as a limiting column 21, which is fixed on the inner side of the shell 2. When the handle body 1 is in the initial position, the limiting column 21 is located directly below the driving column 13. In this state, the hinged portion, the driving column 13 and the limiting column 21 are all located on the same straight line, which can ensure that the reset plate 32 can be arranged normally. Otherwise, the reset plate 32 cannot be arranged on both sides of the driving column 13 and the limiting column 21 at the same time, and cannot play a driving or limiting effect.

[0032] In order to strengthen the limit column 21, the limit column 21 is set as a hollow cylinder, and reinforcement plates are provided on both sides of the limit column 21. The reinforcement plates are connected to the limit column 21 and the shell 2 at the same time. While reducing the weight, the strength of the limit column 21 is strengthened by the two reinforcement plates to prevent it from being broken due to the impact of the reset plate 32.

[0033] Specifically, a concave rotation area 14 is provided on the inner side of the handle body 1. The rotation area 14 is U-shaped as a whole. The hinge part is arranged at the top of the rotation area 14. Two reset plates 32 are rotatably arranged in the rotation area 14, and the movement of the reset plate 32 is restricted within the rotation area 14. That is, when the handle body 1 rotates, its maximum rotation range is that one side of the rotation area 14 is in contact with the reset plate 32 that remains stationary, and it cannot continue to rotate.

[0034] In order to achieve the overall weight reduction of the steering handle, a concave weight reduction groove 15 is provided on the inner side of the two pressing parts 12, and a plurality of cross-arranged reinforcing ribs 16 are provided in the weight reduction groove 15. The weight reduction groove 15 can greatly reduce the weight of the handle body 1, and the reinforcing ribs 16 can improve the strength of the handle body 1.
