The second spring 2422 is sleeved on the rear push-pull rod 2421, and two ends of the second spring are respectively abutted against shoulders of the outer circumferential surfaces of the connecting side plate 2524 and the rear push-pull rod 2421 so as to elastically push the clutch tube 252, thereby playing a role in protection.
The front upper end of the front push-pull rod 241 is hinged to the lower end of the handle 21. Specifically, both ends of the rotating shaft 2111 of the supporting wheel 211 extend to the outside of the assembly groove 2222, for connection of the front upper end of the front push-pull rod 241. Therefore, when the handle 21 swings up and down, the clutch tube 252 can be driven to move back and forth by the linkage of the front push-pull rod 241 and the rear push-pull rod 2421.
In order to protect the push-pull rod set 24, a guide reinforcing pipe 2423 is welded on the connection seat 222, the guide reinforcing pipe 2423 is coaxially sleeved on the rear push-pull rod 2421, and the outer side wall is welded on the U-shaped frame 2223 at the back of the connection seat 222. During manual steering, the handle 21 drives the connecting seat 222 to rotate left and right, the guide reinforcing pipe 2423 synchronously rotates along with the connecting seat 222, and simultaneously drives the rear push-pull rod 2421, the clutch pipe 252 and the clutch plate 251 to rotate, so that in the process, the stress of the connecting point between the front push-pull rod 241 and the rear push-pull rod 2421 and the connecting point between the front push-pull rod 241 and the rotating shaft 2111 can be reduced, the steering torque force can be increased, the manual steering is facilitated, and the push-pull rod group 24 can be protected.
As shown in fig. 1, a side plate 111 corresponding to the handle 21 on the frame 11 is provided with a damping positioning frame 117 for being abutted against when the handle 21 is switched to a vertical position, a first positioning hole is formed in the damping positioning frame 117, a positioning plate 213 is arranged on the handle 21, a second positioning hole is formed in the positioning plate 213, and when the handle 21 is in the vertical position, the first positioning hole corresponds to the second positioning hole up and down, and positioning pins are arranged in a penetrating manner. Through shock attenuation locating rack 117, locating plate 213 and locating pin, can lock handle 21 of vertical state, be convenient for turn to clutch assembly 25 when under the separation state, through handle 21 pulling electric motor car, promote the flexibility of use.
When the energy-saving electric vehicle is particularly used, the corresponding remote controller is configured and connected with a control board of the energy-saving electric vehicle in a wireless manner through wireless control signals such as infrared rays, so as to control the steering motor 51 and the driving motor 6 to operate, the steering motor 51 controls the front wheels 13 to steer through the motor board 52 and the front wheel bogie 4, and the driving motor 6 drives the two front wheels 13 and the two rear wheels 12 to rotate and operate, so that the electric movement and steering of the energy-saving electric vehicle are realized.
When manual pushing and pulling is used, the positioning pin of the locking handle 21 is pulled out, the handle 21 is pressed down, the supporting wheel 211 at the lower end of the handle 21 is pressed down by the rotating shaft 2111 of the front push-pull rod 241, the front push-pull rod 241 pushes the rear push-pull rod 2421 to retreat, the second spring 2422 on the rear push-pull rod 2421 elastically pushes the clutch tube 252 to retreat, so that the clutch tube 252 is sleeved on the upper plate body 2512, and the combination of the clutch tube 252 and the clutch plate 251 is realized; in this state, the handle 21 is swung left and right, so that the steering seat 22 can be driven to swing left and right, the guide reinforcing pipe 2423 synchronously acts, and the torsion is directly transmitted to the connecting side plate 2524 of the clutch pipe 252 through the rear push-pull rod 2421, so that the clutch pipe 252 and the clutch plate 251 are driven to rotate, the clutch plate 251 drives the driving plate 41, the steering plate 42 and the front wheel 13 to synchronously act, the manual steering function of the front wheel 13 is realized, and the push-pull electric vehicle of an operator is convenient to move and steer;
After the handle 21 is released or the handle 21 is swung up, the push-pull rod group 24 and the clutch tube 252 are moved in the opposite direction to disengage the clutch tube 252 from the upper plate body 2512 of the clutch plate 251, and in this case, the clutch tube 252 and the handle 21 do not participate in the steering operation of the front wheel 13.
It should be noted that, after the handle 21 rotates downward from the vertical position by a certain angle, the clutch tube 252 and the upper plate 2512 can be combined, in this embodiment, the handle 21 can be pressed down by a range of 30 ° to 60 ° to sleeve the clutch tube 252 on the upper plate 2512, the pressing angle ranges all consider that the handle 21 is in the pressing position, the difference is only the sleeved depth, but the combination and linkage of the clutch tube 252 and the clutch plate 251 are not affected, so that the handle 21 can be allowed to swing up and down in a certain range in the manual steering process; in the process of rotating 0 to 30 degrees, the connection head 25121 gradually enters the pipe hole of the clutch pipe 252, in this case, due to the guide surface 25122 on the connection head 25121 and the existence of the lengthened portion 2522 on the clutch pipe 252, the inner wall of the side wall at the rear end of the clutch pipe 252 cannot be attached to and abutted against the guide surface 25122, so that the clutch pipe 252 cannot drive the clutch plate 251 to rotate synchronously, that is, the clutch pipe 252 and the clutch plate 251 can rotate relatively, so that the handle 21 can also rotate left and right in this process, the clutch pipe 252 is driven to rotate synchronously, the orientation of the pipe orifice at the rear end of the clutch pipe 252 is adjusted, the clutch pipe 252 and the upper plate 2512 are aligned directly, the clutch pipe 252 is pushed into the upper plate 2512 conveniently, and the situation can be applied to the situation that the front wheel 13 cannot be aligned in a steering way or alignment is difficult; the 60 ° pushing down is the lowest pushing down position, in this case, two ends of the rotating shaft 2111 of the supporting wheel 211 will abut against the limit supporting portion 2221, and cannot be pushed down further.
