DETAILED DESCRIPTION
[0022] The following is the specific embodiment of the utility model and is further described the technical scheme of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.
[0023] As Figs. 1-3 Indicated, a kind of steering handle of high-precision reset can be realized, including handle main body 1, shell 2 and reset piece 3, wherein handle main body 1 is connected with the steering control unit of vehicle body, and the steering control unit can be controlled vehicle body steering by it.
[0024] Specifically, the shell 2 is fixed on the vehicle body, 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 located at the initial non-steering position, the two pressing parts 12 are both extended outside the shell 2, by pressing the two pressing parts 12, the handle body 1 can be driven to rotate around the hinge part, and according to the forward rotation and reverse rotation of the handle body 1, the vehicle can be controlled to turn left or right.
[0025] Wherein, the handle body 1 is provided with a driving part, the inside of the shell 2 is provided with a limiting part, in the initial position, the driving part and the limiting part are arranged in the shell 2 along the vertical direction, the reset part 3 includes an elastic part and two reset plates 32 symmetrically arranged on both sides of the driving part, one end of the two reset plates 32 is rotatably connected with the hinge part, and the other end of the two reset plates 32 is connected with each other through the elastic part, the two sides of the limiting part can be respectively attached to the inner side of the two reset plates 32, when the handle body 1 is driven to rotate by the pressing part 12, the driving part can rotate with the handle body 1, taking the rotation in the first direction as an example, the driving part can drive the reset plate 32 located on the side of the limiting part towards the first direction to move away from the other reset plate 32, and the other reset plate 32 cannot rotate due to the limitation of the limiting part, so the elastic part between the two reset plates 32 will be stretched, and there is an elastic force, after the external force is removed, the elastic part can drive the initially rotated reset plate 32 to reset, the reset plate 32 drives the handle body 1 to reset through the driving part, and since the reset plate 32 is limited by the limiting part after resetting to the initial position, it cannot pass through the limiting part, so high-precision resetting can be achieved, and the handle body 1 is prevented from shaking.
[0026] Wherein, the driving part is provided as a driving column 13, the driving column 13 is fixed on the handle body 1, and when the handle body 1 is located at 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 attached to the inner side of the two reset plates 32, which facilitates the driving of the two reset plates 32 to rotate away from each other.
[0027] In order to ensure that the rotation angles of the reset plates 32 and the handle body 1 are synchronous, the hinge part is provided as a first positioning hole 11, one end of each of the two reset plates 32 is provided with a second positioning hole 321, the two second positioning holes 321 are in communication with the first positioning hole 11, a rotating shaft is arranged in the communication hole of the first positioning hole 11 and the second positioning hole 321, one end of the rotating shaft is rotatably connected with 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 on the same straight line, their rotation angles can be consistent, and the reset plates 32 can be synchronously driven to rotate.
[0028] In the embodiment, the steering control unit is connected with the rotating shaft, the rotating angle of the rotating shaft is consistent with the rotating angle of the handle body 1, and the vehicle body can be controlled to steer in proportion to the rotating angle of the handle body 1.
[0029] Specifically, the elastic member is a reset spring 31, two ends of the reset spring 31 are connected with two reset plates 32 respectively away from one end of 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 is increasing, which will stretch the reset spring 31, when the force applied by the operator is greater than the elastic force, the elastic force can be overcome to continue to rotate, and when the operator no longer applies the force to the handle body 1, the elastic force can be used as a reset force to drive the reset.
[0030] In order to realize the quick positioning of the reset spring 31 and the reset plate 32, the outer side of the reset plate 32 away from the second positioning hole 321 is provided with a positioning groove 322, and the two ends of the reset spring 31 are provided with hooks 311, the hooks 311 can be extended into the positioning groove 322 and buckled with the reset plate 32, that is, when installing, only the hooks 311 at both ends of the reset spring 31 need to be directly hung into the positioning groove 322, which is simple and fast.
[0031] Specifically, the limiting member is a limiting column 21, the limiting column 21 is fixed to 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 hinge part, the driving column 13 and the limiting column 21 are located on the same straight line, which can ensure that the reset plate 32 can be normally arranged, 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 the driving or limiting effect.
[0032] In order to strengthen the strength of the limiting column 21, the limiting column 21 is a hollow column, and the two sides of the limiting column 21 are provided with reinforcing plates, the reinforcing plates are connected with the limiting column 21 and the shell 2 at the same time, which can strengthen the strength of the limiting column 21 through the two reinforcing plates while reducing the weight, so as to avoid the fracture of the limiting column 21 due to the impact of the reset plate 32.
[0033] Specifically, the inner side of the handle body 1 is provided with an inner concave rotating area 14, the rotating area 14 is in a whole U shape, the hinge part is arranged at the top of the rotating area 14, and the two reset plates 32 are rotatably arranged in the rotating area 14, so that the movement of the reset plate 32 is limited in the rotating area 14, that is, when the handle body 1 rotates, the maximum rotating range is that one side of the rotating area 14 is in contact with the stationary reset plate 32, so that the handle body 1 cannot continue to rotate.
[0034] In order to realize the weight reduction of the steering handle, the inner side of the two pressing parts 12 is provided with an inner concave weight reduction groove 15, and a plurality of reinforcing ribs 16 are arranged in the weight reduction groove 15, so that the weight of the handle body 1 can be greatly reduced, and the strength of the handle body 1 can be improved through the reinforcing ribs 16.
