[0034] For example, the power transmission structure includes a worm 29, both sides of which are rotatably connected to a worm support base assembly 30, and both ends of the worm 29 are fixedly connected to a second bevel gear 28 by a flat key, the second bevel gear 28 is meshed with the first bevel gear 27, and the power output structure connected to the worm 29 transmits power to the worm 29, the worm 29 transmits power to the second bevel gear 28, and the second bevel gear 28 transmits power to the first bevel gear 27 to rotate it, and the lead screw 12 rotates synchronously with the first bevel gear 27, so that the ball nut 32 can be displaced up and down.

[0035] It should be noted that a bearing is provided inside the worm support base assembly 30 , and the worm 29 is connected to the bearing inside the worm support base assembly 30 .

[0036] For example, the power output structure includes a reducer 31 and a motor mounting seat 17, wherein the reducer 31 is fixedly mounted on the motor mounting seat 17 by countersunk screws, the input end of the reducer 31 is connected to the output end of the servo motor 19, and the output shaft of the reducer 31 passes through the motor mounting seat 17 and is connected to the worm gear 33 with a flat key. When the servo motor 19 rotates, the power is transmitted to the reducer 31 to increase the torque and reduce the speed, and the worm gear 33 rotates synchronously with the reducer 31.

[0037] See also Figure 6 , Figure 7 and Fig. 9 In some preferred embodiments of the present invention, the control device includes a button box 8 and a servo controller 43, the button box 8 is arranged on one side of the chassis and is provided with a display screen 35, an ascending button 36, a descending button 37, an emergency stop button 38, a power indicator light 39 and a start button 40, and the servo controller 43 is arranged at the bottom of the chassis for controlling the servo motor 19. The module lifting structure includes a bottom plate 14 and a first bracket 15, the bottom plate 14 is fixed on four ball nuts 32, and can move up and down synchronously with the ball nuts 32, and the bottom plate 14 is fixedly connected with a second bracket 20; the first bracket 15 is fixed on the second column 22 and the first bracket 15 is fixedly connected with a photoelectric switch 13, when the second bracket 20 passes the photoelectric switch 13, the photoelectric switch 13 will transmit a signal to the servo controller 43, and the start, stop, ascend and descend functions of the servo motor 19 can be controlled by the ascending button 36, the descending button 37, the emergency stop button 38 and the start button 40. The display screen 35 displays information such as the displacement speed, displacement distance, and rotation speed of the servo motor 19 of the module lifting structure.

[0038] See also Figure 8 The module lifting structure also includes a limiting structure, which includes a first module baffle 41 and a second module baffle 42. The first module baffle 41 is arranged on both sides of the bottom plate 14, and the second module baffle 42 is evenly arranged between the first module baffle 41. Module 7 is placed between the second module baffle 42 and the first module baffle 41, which can limit the left and right movement of module 7. A baffle can be installed in front of the second module baffle 42 and the first module baffle 41 to ensure that module 7 does not move forward and backward during the lifting process and fall.

[0039] For example, the present invention is made of aluminum profiles and aluminum plates as a whole, which has the advantages of simple assembly and good processability. Screws are used to fix various parts, which makes assembly simple and convenient with low cost.

[0040] Working principle: First, determine the height to which the module needs to be lifted, and set the lifting parameters through the control device located on one side of the chassis. The button box 8 in the control device is provided with various operation buttons and a display screen 35. Press the start button 40, and set the lifting direction in combination with the up button 36 and the down button 37. Place the module to be lifted on the module lifting structure. The servo controller 43 transmits an electrical signal to the servo motor 19 in the power output structure. After receiving the command, the servo motor 19 starts to rotate and outputs power to the reducer 31 connected thereto. The output shaft of the reducer 31 is connected to the servo motor 19, and the power of the servo motor 19 is increased to increase the torque and reduce the speed. The worm gear 33 is then driven to rotate synchronously through the output shaft. The power output from the worm gear 33 enters the worm 29, and the rotation of the worm gear 33 drives the worm 29 to rotate. The worm 29 is supported on both sides by the worm support base assembly 30, and its internal bearings ensure smooth rotation. The second bevel gears 28 at both ends of the worm 29 mesh with the first bevel gear 27 at the bottom of the screw 12. As the worm 29 rotates, the power is transmitted through the bevel gears and accurately transmitted to the two screws 12. The two screws 12 rotate synchronously under the power. Since the ball nut 32 in the middle of the screw 12 relies on the rolling friction principle of the ball, it cannot follow the screw 12 to make a circular motion, and can only move linearly along the axial direction of the screw 12. The bottom plate 14 of the modular lifting structure is fixed on four ball nuts 32, so the bottom plate 14 will move synchronously with the up and down movement of the ball nuts 32, driving the bottom plate 14 placed thereon to achieve lifting or lowering. During the lifting process, the first bracket 15 fixed on the second column 22 is provided with a photoelectric switch 13. When the second bracket 20 of the module lifting structure passes the photoelectric switch 13, the photoelectric switch 13 transmits the position signal to the servo controller 43, thereby accurately monitoring the lifting height and achieving accurate positioning in conjunction with the control button. In addition, the first module baffle 41 and the second module baffle 42 in the limit structure will limit the left and right movement of the module 7. If necessary, installing a baffle on the front side can also prevent the module 7 from moving forward and backward, thereby avoiding the danger of the module falling during lifting.

[0041] For example, the present invention also provides a method for using a charger module lifting device, comprising placing a module to be lifted on a module lifting structure, starting a power output structure through a control device, transmitting power to a power transmission structure, the power transmission structure transmitting power to a ball screw assembly, the ball screw assembly moves linearly upward relative to a chassis under the action of power, and installing the module after lifting is completed; The power output structure is reversed through the control device, and the power is transmitted to the power transmission structure. The power transmission structure transmits the power to the ball screw assembly. Under the action of the power, the ball screw assembly moves linearly downward relative to the chassis, and the module lifting structure descends to the initial height.
