Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0026] The following gives specific embodiments.
[0027] Please refer to Figures 1 - 4 , the present utility model provides a technical solution: an electric trolley control handle, including a handle 1, characterized in that: a connecting rod 2 is fixedly connected to the lower part of the handle 1.
[0028] Furthermore, as shown in Figure 1 , Figure 3 and Figure 4 , the connecting rod 2 includes a fixing seat 21 and a limit - able connecting seat 22. A first hollow tube 23 is fixedly connected by fitting on the upper left side of the fixing seat 21, and a second hollow tube 24 is fixedly connected by fitting on the upper right side of the fixing seat 21. Fixing holes 241 are provided on the upper front side of the outer surface of the first hollow tube 23 and the upper front side of the outer surface of the second hollow tube 24. Wire - routing holes 25 are provided on the lower front side and the upper right side of the outer surface of the second hollow tube 24. A first movable hole 26 is provided in the middle of the upper side of the fixing seat 21. A fixing rod 27 is fixedly connected by fitting in the middle of the lower side of the limit - able connecting seat 22. A connecting frame 28 is fixedly connected to the lower part of the fixing rod 27. Second movable holes 29 are provided on the upper left side and the upper right side of the limit - able connecting seat 22. The first hollow tube 23 and the second hollow tube 24 are respectively slidably connected to the two second movable holes 29, and the fixing rod 27 is slidably connected to the first movable hole 26.
[0029] Through the above solution: By setting the connecting rod 2 into a retractable structure, when the connecting rod 2 is connected to the electric trolley for use, the length of the connecting rod 2 can be adjusted according to the height of the user or the usage requirements, so that the device can be used to adapt to users of different heights and different usage requirements.
[0030] Further, as Figure 1 and Figure 2 shown, the handle 1 includes a housing 11. A Hall acceleration rod module 13 is arranged on the right side inside the housing 11. A self-resetting contact key switch 14 is snap-connected to the upper right side of the housing 11. An electronic control main board 15 is fixedly installed on the right side of the rear part inside the housing 11. An external wiring 151 is welded to one side of the electronic control main board 15. A display screen 16 is snap-connected to the left side of the front part of the housing 11. A two-gear key switch 17 and a three-gear key switch 18 are snap-connected to the right side of the front part of the housing 11. Both the two-gear key switch 17 and the three-gear key switch 18 are snap-connected to the electronic control main board 15. Two mounting holes 12 distributed left and right are formed in the middle of the lower side of the housing 11, and the two mounting holes 12 are respectively fitted and fixedly connected to the first hollow tube 23 and the second hollow tube 24.
[0031] Through the above solution: By providing multiple control buttons in the handle 1, during use, the control operation of multiple signals can be realized. When the device is installed in an electric trolley for use, diversified control can be achieved, which is more convenient for controlling the electric trolley. When electrically connecting the handle to the electric trolley, first pass the external wiring 151 through the wiring hole 25 in the upper part of the second hollow tube 24 into the inside of the second hollow tube 24, and then lead out the external wiring 151 through the wiring hole 25 in the lower part of the second hollow tube 24, so that it is convenient for the handle to be electrically connected to the electric trolley through the external wiring 151.
[0032] Working principle: When the device is in use, first fix the handle to the electric trolley through the connecting frame 28, and then electrically connect the external wire 151 to the electric trolley. Then the electric trolley can be operated through the handle. When operating with the handle subsequently, by pressing the two-gear button switch 17, a switching on / off signal of one path is provided to the electronic control main board 15 to control the power on / off of the system. By pressing the three-gear button switch 18, switching on / off signals of two paths are provided to the electronic control main board 15 to control the system to output the normal driving gear, high-speed driving gear and reverse gear. The display screen 16 is connected to the electronic control main board 15 to display the current power on / off state and the remaining power. During the use of the device, swing the accelerator lever in the Hall accelerator lever module 13 by hand, and the internal magnet of the rotating module moves relative to the Hall sensor, so as to provide a linearly changing signal input to the electronic control main board 15. Release the accelerator lever, and under the action of the torsion spring inside the module, the accelerator lever returns to its original position. During the use process, swing the accelerator lever according to the required speed. The larger the rotation angle of the accelerator lever, the greater the corresponding output speed of the controller. Subsequently, press the self-resetting contact button switch 14 to provide a switching on / off signal of one path to the electronic control main board 15 to control the electromagnetic brake of the system to decelerate. Release the button switch and it will self-reset, and the system returns to normal. When the system runs out of power, the trolley can be directly pushed and pulled manually by pulling the handle 1.
[0033] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
