[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0021] Example 1 Embodiment 1 of this application discloses a charging gun mobile device.

[0022] Reference Figure 1 The charging gun mobile device includes a mounting frame 1, a movable frame 2 slidably connected to the mounting frame 1, a first driving device for driving the movable frame 2 to move on the mounting frame 1, a support frame 3 slidably connected to the movable frame 2, a second driving device for driving the support frame 3 to move on the movable frame 2, and a robotic arm 4 mounted on the support frame 3. The robotic arm 4 is used to drive the charging gun 5 to move. In this embodiment, the charging gun 5 is fixedly mounted on the end of the robotic arm 4.

[0023] Therefore, when it is necessary to insert the charging gun 5 into the charging interface, the first drive device is activated to move the moving frame 2, and the second drive device is activated to move the support frame 3 and the robotic arm 4. The charging gun 5 on the robotic arm 4 is moved to the position corresponding to the charging interface, and the charging gun 5 is inserted into the charging interface through the robotic arm 4, realizing the automatic insertion and charging of the vehicle. The mechanical system completes the steps of moving and inserting and unplugging the charging gun 5, freeing up manpower, reducing physical burden and fatigue, and at the same time, it is convenient to use the mechanical structure to realize the automatic insertion and unplugging of the charging gun 5 in the case of limited space, thus improving the ease of operation and portability.

[0024] Reference Figure 1 It also includes a robot track set on the ground, with the mounting frame 1 mounted on a slide of the robot track. In this embodiment, the robot track can be a semi-enclosed robot track, and the mounting frame 1 is mounted on the slide of the semi-enclosed robot track. Therefore, starting the robot track moves the mounting frame 1 at the moving end of the robot track, improving the flexibility of the mounting frame 1's position and facilitating the movement and resetting of the mounting frame 1.

[0025] Reference Figure 1 The movable frame 2 is slidably connected to the mounting frame 1 in the vertical direction. The first driving device includes a first lifting wheel 6 and a second lifting wheel rotatably connected to the mounting frame 1. The mounting frame 1 is provided with a first driving part that drives the first lifting wheel 6 to rotate. A lifting belt 7 is tautly wound between the first lifting wheel 6 and the second lifting wheel. A lifting frame 8 is fixedly connected to the lifting belt 7. A lifting screw is rotatably connected to the lifting frame 8. A second driving part that drives the lifting screw to rotate is provided on the lifting frame 8. In this embodiment, the first driving part and the second driving part can be a drive motor. The first lifting wheel 6 and the lifting screw are respectively located at the output end of the drive motor. The outer edge of the lifting screw is threaded with a lifting nut that matches the size of the lifting screw. The movable frame 2 is located on the lifting nut.

[0026] Therefore, the first drive unit is started, which drives the first lifting wheel 6 at the output end of the first drive unit to rotate. The rotation of the first lifting wheel 6 drives the lifting frame 8 on the lifting belt 7 to rise and fall in the vertical direction. The second drive unit is started, which drives the lifting screw at the output end of the second drive unit to rotate. The rotation of the lifting screw drives the lifting nut and the moving frame 2 to move along the length of the lifting screw, thereby realizing the multi-stage lifting of the moving frame 2 and facilitating the adjustment of the height of the charging gun 5 on the moving frame 2.

[0027] Reference Figure 1The second driving device includes a horizontal lead screw 14 rotatably connected to the movable frame 2. The movable frame 2 is equipped with a fifth driving unit that drives the horizontal lead screw 14 to rotate. In this embodiment, the fifth driving unit is a drive motor. The horizontal lead screw 14 is coaxially fixedly connected to the output end of the drive motor. A horizontal nut 15 matching the size of the horizontal lead screw 14 is threaded onto the outer edge of the horizontal lead screw 14. The support frame 3 is mounted on the horizontal nut 15. Therefore, activating the fifth driving unit rotates the horizontal lead screw 14 at its output end, causing the horizontal nut 15 to slide along the length of the horizontal lead screw 14, thus adjusting the horizontal position of the charging gun 5 on the support frame 3.

[0028] Reference Figure 1 The robotic arm 4 includes a support arm 19 mounted on a support frame 3. Several rotating arms 20 are rotatably connected to the support arm 19 in sequence. An eighth drive unit for driving the rotating arms 20 to rotate is provided between the support arm 19 and the adjacent rotating arms 20. A ninth drive unit for driving the rotating arms 20 to rotate is provided between two adjacent rotating arms 20 respectively. The charging gun 5 is mounted on the rotating arm 20 at the end away from the support arm 19. In this embodiment, the eighth and ninth drive units can be drive motors. In addition, the number and size of the rotating arms 20 can be set according to the actual situation. In this embodiment, a six-axis collaborative explosion-proof robotic arm 4 is used as an example for illustration. The core advantage of the six-axis robotic arm 4 is that it has six degrees of freedom of motion, which enables it to achieve extremely flexible and almost arbitrary posture and position adjustment in three-dimensional space, making it convenient to insert and remove the gun from the vehicle in narrow spaces. In this embodiment of the application, a vision system is provided on the cantilever on which the charging gun 5 is installed. The vision system includes an image acquisition unit and a control terminal. The image acquisition unit uses a camera. The camera transmits the captured vehicle image signal to the control terminal. The control terminal adjusts the position and posture of the charging gun 5 according to the vehicle image signal, so that the charging gun 5 can be accurately inserted into the charging interface of the vehicle.

[0029] The implementation principle of Embodiment 1 of this application is as follows: When it is necessary to insert the charging gun 5 into the charging interface, the first drive unit is activated, which drives the first lifting wheel 6 at the output end of the first drive unit to rotate. The rotation of the first lifting wheel 6 drives the lifting frame 8 on the lifting belt 7 to rise and fall in the vertical direction. The second drive unit is activated, which drives the lifting screw at the output end of the second drive unit to rotate. The rotation of the lifting screw drives the lifting nut and the moving frame 2 to move along the length of the lifting screw, realizing multi-stage lifting of the moving frame 2, which facilitates the adjustment of the height of the charging gun 5 on the moving frame 2. The fifth drive unit is activated, which drives the horizontal screw 14 at the output end of the fifth drive unit to rotate, which drives the horizontal nut 15 to slide along the length of the horizontal screw 14, realizing the horizontal position of the charging gun 5 on the support frame 3 is adjustable. The charging gun 5 is moved to the position corresponding to the charging interface by the robotic arm 4, and the charging gun 5 is inserted into the charging interface, realizing the automatic charging of the vehicle. The mechanical system completes the steps of moving and inserting / removing the charging gun 5, freeing up manpower, reducing physical burden and fatigue, and at the same time, it is convenient to realize the automatic insertion and removal of the charging gun 5 by using the mechanical structure in the case of limited space, thus improving the ease of operation and portability.

[0031] The implementation principle of Embodiment 2 of this application is as follows: When it is necessary to insert the charging gun 5 into the charging interface, the first drive unit is activated, which drives the first lifting wheel 6 at the output end of the first drive unit to rotate. The rotation of the first lifting wheel 6 drives the lifting frame 8 on the lifting belt 7 to rise and fall in the vertical direction. The second drive unit is activated, which drives the lifting screw at the output end of the second drive unit to rotate. The rotation of the lifting screw drives the lifting nut and the moving frame 2 to move along the length of the lifting screw, thereby realizing the multi-stage lifting of the moving frame 2 and facilitating the adjustment of the height of the charging gun 5 on the moving frame 2. The fifth drive unit is activated, causing the horizontal lead screw 14 at its output end to rotate, which in turn causes the horizontal nut 15 to slide along the length of the horizontal lead screw 14. The sixth drive unit is activated, causing the first horizontal wheel 16 at its output end to rotate, which in turn causes the second horizontal frame 17 on the first horizontal belt to slide. The seventh drive unit is activated, causing the third horizontal wheel 18 at its output end to rotate, which in turn causes the support frame 3 on the second horizontal belt to move, thereby achieving multi-level adjustment of the horizontal position of the charging gun 5 on the support frame 3. The robotic arm 4 moves the charging gun 5 to the position corresponding to the charging interface and inserts the charging gun 5 into the charging interface to realize the automatic charging of the vehicle. The mechanical system completes the steps of moving and plugging in the charging gun 5, freeing up manpower, reducing physical burden and fatigue, and at the same time, it is convenient to use the mechanical structure to realize the automatic plugging in and unplugging of the charging gun 5 in the case of limited space, thus improving the ease of operation and portability.

[0032] Example 3 Reference Figure 3 The difference between Embodiment 3 and Embodiment 1 is that the movable frame 2 is slidably connected to the mounting frame 1 in a horizontal direction. The first driving device includes a first side-shifting wheel 9 and a second side-shifting wheel rotatably connected to the mounting frame 1. A third driving part for driving the first side-shifting wheel 9 to rotate is provided on the mounting frame 1. A side-shifting belt 10 arranged in a horizontal direction is tautly wound between the first side-shifting wheel 9 and the second side-shifting wheel. A first side-shifting frame 11 is provided on the side-shifting belt 10. A side-shifting screw 12 arranged in a horizontal direction is rotatably connected to the first side-shifting frame 11. A driving side-shifting screw is provided on the first side-shifting frame 11. The fourth drive unit 12 rotates. In this embodiment, the third and fourth drive units are driven by motors. The outer edge of the lateral lead screw 12 is threaded with a lateral nut matching the size of the lateral lead screw 12. A second lateral frame 13 is bolted to the lateral nut. The moving frame 2 slides vertically onto the second lateral frame 13. A lifting unit for driving the moving frame 2 to rise and fall is provided on the second lateral frame 13. In this embodiment, the lifting unit can use a lead screw and nut pair to drive the moving frame 2 to rise and fall, or it can use a belt and pulley set to drive the moving frame 2 to rise and fall, which will not be elaborated here. In this embodiment, the support frame 3 can be bolted to the top of the moving frame 2, or it can slide horizontally onto the moving frame 2 according to the specific structure of the second drive device, which is not limited here.

[0033] The implementation principle of Embodiment 3 of this application is as follows: When it is necessary to insert the charging gun 5 into the charging interface, the third drive unit is activated, which drives the first side shift wheel 9 at the output end of the third drive unit to rotate. The rotation of the first side shift wheel 9 drives the first side shift frame 11 on the side shift belt 10 to slide horizontally. The fourth drive unit is activated, which drives the side shift screw 12 at the output end of the fourth drive unit to rotate, which drives the side shift nut and the second side shift frame 13 to slide along the length direction of the side shift screw 12, realizing multi-stage sliding of the moving frame 2 in the horizontal direction, which is more flexible. The lifting unit is activated to drive the moving frame 2 to lift, which makes it easy to adjust the height of the charging gun 5 on the support frame 3. The charging gun 5 is moved to the position corresponding to the charging interface by the robotic arm 4, and the charging gun 5 is inserted into the charging interface to realize the automatic charging of the vehicle. The mechanical system completes the steps of moving and inserting / removing the charging gun 5, freeing up manpower, reducing physical burden and fatigue, and at the same time, it is easy to realize the automatic insertion / removal of the charging gun 5 by using the mechanical structure in the case of limited space, which improves the ease of operation and portability.
