[0046] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0047] The embodiments of the present application provide a method for controlling the movement of a convenient charging device and an auxiliary charging device to solve the problem in the related art that the charging gun body and the high-voltage wiring harness are heavy, making it difficult to align the charging port.

[0048] See also Figure 1-Figure 2 , provides a convenient charging device, which includes:

[0049] The charging pile body 1 is provided with a vertical movement component 2;

[0050] The hinge seat 3 is connected to the vertical moving assembly 2 through the horizontal moving assembly 4; the vertical moving assembly 2 is used to drive the horizontal moving assembly 4 to move up and down; the horizontal moving assembly 4 is provided with a self-locking mechanism;

[0051] The telescopic rod 5 has one end connected to the hinge seat 3 via a rotating assembly 6;

[0052] The charging gun 7 is hinged to the other end of the telescopic rod 5 and is provided with a pressing control member 8; the pressing control member 8 is used to control the rotating assembly 6 and the vertical moving assembly 2 through the pressing force received.

[0053] When in use, the pressing control part 8 is used to control the rotating assembly 6 to rotate the telescopic rod 5 and the charging gun 7 to the horizontal direction through the pressing force, and then the telescopic rod 5 is used to move the charging gun 7 to the vicinity of the charging port. Then, the vertical movement assembly 2 is controlled by pressing the control part 8 to move the charging gun 7 to a suitable height. At the same time, the transverse movement assembly 4 is unlocked to facilitate the adjustment of the transverse position of the charging gun and finally align the charging gun 7 with the charging port. The whole process does not require the human arm to bear the weight, which facilitates alignment with the charging port.

[0054] In this embodiment, the telescopic rod 5 can be a telescopic rod similar to an umbrella, which is manually extended and retracted. The rotating assembly 6 is activated only after the pressing control part 8 is pressed to the maximum depth, and then the telescopic rod 5 is moved to the horizontal position; the self-locking mechanism is provided in the transverse movement assembly 4 because in this embodiment, in the process of moving the charging gun 7 to the charging port, the height of the charging gun 7 is controlled by the change of the pressure signal after the pressing control part 8 is released. The distance that the vertical movement assembly 2 moves the transverse movement assembly 4, when it moves to the appropriate height, the pressing control part 8 will stop moving when there is no force. At this time, the charging gun 7 needs to be manually moved laterally to allow the charging gun 7 to move on the transverse movement assembly 4. In the actual process, vertical adjustment and transverse movement are carried out simultaneously, so the self-locking mechanism needs to be unlocked; after the pressing control part 8 is no longer under force, the self-locking mechanism is locked to ensure its position.

[0055] In addition, since the telescopic rod 5 is pulled horizontally, the force used at this time is also minimal, and vertical and lateral movements basically do not require manual force, thus solving the problem in the related art that the charging gun body and high-voltage wiring harness are heavy, which makes it difficult to align with the charging port.

[0056] In some preferred embodiments, the telescopic rod 5 may include an electric telescopic rod or a pneumatic telescopic rod;

[0057] The charging pile body 1 is provided with a power source for driving an electric telescopic rod or an air pump for driving a pneumatic telescopic rod.

[0058] The advantage of this setting is that it can be extended and retracted without requiring manual force, thereby further reducing the impact of the charging gun's weight.

[0059] In some preferred embodiments, the specific structures of the vertical movement assembly 2 and the horizontal movement assembly 4 are as follows:

[0060] A vertical groove is provided on the charging pile body 1;

[0061] The vertical movement assembly 2 includes a screw rod 200 disposed in a vertical slot, a first moving block 201 being threadedly connected to the screw rod 200, and a first drive motor 202 being connected to the bottom of the screw rod 200;

[0062] The first moving block 201 is provided with a transverse moving component mounting surface.

[0063] In the above, the first drive motor 202 drives the screw rod 200 to rotate. Since the first moving block 201 and the screw rod 200 are threadedly connected, the structure itself has a self-locking function. Therefore, the first drive motor 202 does not need a self-locking structure. Of course, after the first moving block 201 exceeds the required height, since the pressing control part 8 has been completely released, a button can be set to control it if it needs to be lowered.

[0064] The transverse movement assembly 4 includes a transverse guide rail 400 connected to the transverse movement assembly mounting surface. The transverse guide rail 400 is provided with a slide groove arranged along its length, and a rack 401 is arranged in the slide groove. The transverse guide rail 400 is also provided with a T-shaped guide groove 402 parallel to the slide groove.

[0065] The traverse assembly 4 also includes a second movable block 403. The bottom of the second movable block 403 is provided with a T-shaped block slidably connected to the T-shaped guide slot 402, and a gear 405 meshing with the rack 401. The gear 405 is connected to a second drive motor 404 with a self-locking mechanism. The second drive motor 404 with a self-locking mechanism can be a servo or a stepper motor.

[0066] When the transverse movement assembly 4 is no longer under control and drives the second drive motor 404 to drive the gear 405 to drive the second movable block 403, it can be in two states: unlocked and locked. When unlocked, it can move along the T-shaped guide groove 402 under the action of an external force, thus accommodating manual movement or automatic movement controlled by a signal. The self-locking mechanism refers to the second drive motor 404 with a self-locking mechanism.

[0067] Furthermore, the rotating assembly 6 includes a connecting rod connected to the telescopic rod 5, and both ends of the connecting rod are provided with hinge shafts hinged to the hinge seat 3; one of the hinge shafts is connected to a third drive motor with a self-locking mechanism.

[0068] In some preferred embodiments, there are two stages in the charging process: one is to move the charging gun 7 to the charging port and complete preliminary alignment; the other is to insert the charging gun 7 into the charging port. Since the former stage is the preliminary alignment, there may be a deviation in the insertion angle. Therefore, the following settings are provided:

[0069] A plurality of first pressure sensors 9 distributed in an annular pattern are provided on the outer periphery of the charging gun 7;

[0070] The convenient charging device also includes a calibration control component connected to multiple first pressure sensors 9; the calibration control component is used to control the transverse movement assembly 4 and the vertical movement assembly 2 according to the pressure signals of multiple first pressure sensors 9 in the process of controlling the extension and retraction of the telescopic rod 5, so that the center of the charging gun 7 and the center of the charging port are coaxial.

[0071] In this embodiment, the angle at which the charging gun 7 is inserted into the charging port is adjusted. During the process of the telescopic rod 5 driving the charging gun 7 to be inserted, the lateral movement component 4 and the vertical movement component 2 can be controlled according to the pressure signals of the multiple first pressure sensors 9 to perform lateral and vertical movements. When moved into place, the pressure signals of the multiple first pressure sensors 9 are basically equal to the second threshold value; the second threshold value is pre-designed according to different charging guns 7 and charging ports.

[0072] In some preferred embodiments, the specific structure of the pressing control member 8 is explained as follows:

[0073] In the first structure, the charging gun 7 is provided with a mounting groove; the pressing control member 8 includes an elastic member 10 disposed in the mounting groove; the bottom of the elastic member 10 is connected to a second pressure sensor 11, and the top is connected to a button; or,

[0074] In the second structure, a mounting groove is provided on the charging gun 7; the pressing control part 8 includes an elastic part 10 arranged in the mounting groove, and a pressure rod 12 hinged on the charging gun 7; the bottom of the elastic part 10 is connected to a second pressure sensor 11, and the end of the pressure rod 12 away from the hinge point is provided with a holding portion; the holding portion extends into the mounting groove and contacts the top of the elastic part 10.

[0075] The second pressure sensor 11 is associated with multiple force points on the third drive motor, first drive motor 202, second drive motor 404, and the charging gun cable. The magnitude of the force at each point is correlated with the depth of the button press. The force on the telescopic rod 5 is FA = k1x, with FA pointing perpendicular to the rod and upward. The force on the charging cable is FB = k2x, with FB pointing parallel to the charging pile and upward. k1 and k2 are force constants, and x is the button press depth. The in-plane force on the charging gun 7 is FC = k3(lx), and FD = k4(lx), with k3 and k4 being force constants, and l being the maximum button press depth.

[0076] Assume that the force applied by the user to the button is F, and the elastic member 10 is a linear spring; the linear spring deformation is x, and the elastic coefficient is k. Then, the second pressure sensor 11 is subjected to the spring force F = F = kx. When the charging pile receives a pressure signal with a value of F, it outputs the force applied to the rotating assembly 6 as FA = k1x according to the pressing depth x.

[0077] The longitudinal and lateral locking forces are FC = k3(lx) and FD = k4(lx). Therefore, the charging station controls the rotating assembly 6 to raise the charging gun 7 from the bottom. When the user presses the button on the charging gun all the way down, the telescopic rod 5 on the charging gun 7 moves to a horizontal position. Because the charging port heights vary from vehicle to vehicle, the user can control the height of the charging gun by adjusting the depth of the button press, significantly reducing the effort required during charging.

[0078] This application also proposes a method for controlling the movement of an auxiliary charging device, which includes the following steps:

[0079] Provide convenient charging equipment;

[0080] When receiving a pressing force signal on the pressing control member 8 for the first time, determining whether the pressing force signal is greater than a first threshold;

[0081] If so, the rotating assembly 6 is controlled to drive the telescopic rod 5 to rotate until the telescopic rod 5 is horizontal; then the pressing force signal is continued to be received, and the vertical moving assembly 2 is controlled to move the horizontal moving assembly 4 according to the size of the received pressing force signal, and the self-locking mechanism is unlocked at the same time;

[0082] Otherwise, the rotating assembly 6 is not controlled to rotate.

[0083] This achieves the goal of driving the rotating assembly 6 and performing subsequent operations only after the push control 8 is pressed to its maximum depth. When moving the charging gun 7 to the charging port, the rotating assembly 6 is activated only after the push control 8 is pressed to its maximum depth, and the telescopic rod 5 is then moved horizontally. The push control 8 is then gradually released. The height of the charging gun 7 is controlled by the pressure signal change after the push control 8 is released, which controls the distance the vertical movement assembly 2 moves the transverse movement assembly 4. When the charging gun 7 reaches the appropriate height, the push control 8 is released and the movement stops. At this point, the charging gun 7 needs to be manually moved laterally to allow it to move on the transverse movement assembly 4. In actual operation, vertical adjustment and transverse movement occur simultaneously, so the self-locking mechanism needs to be unlocked. After the push control 8 is no longer pressed, the self-locking mechanism locks to secure its position. In addition, because the telescopic rod 5 is pulled horizontally, the force used is minimal, and vertical and transverse movement require virtually no manual effort. This solves the problem in related art where the heavy charging gun body and high-voltage wiring harness make alignment with the charging port difficult.

[0084] In some preferred embodiments, the method for controlling the movement of the auxiliary charging device further includes the following steps:

[0085] When the charging gun 7 is inserted into the charging port, the pressure signals of the plurality of first pressure sensors 9 are obtained by using the calibration control component;

[0086] Determining whether the pressure signals of the plurality of first pressure sensors 9 are all equal;

[0087] If yes, it means that the charging gun 7 and the charging port are coaxial;

[0088] Otherwise, the vertical movement component 2 and the horizontal movement component 4 are controlled according to the pressure signals of the multiple first pressure sensors 9 and the positions of the multiple first pressure sensors 9 on the gun head of the charging gun 7.

[0089] According to the pressure signals of the plurality of first pressure sensors 9 and the positions of the plurality of first pressure sensors 9 on the tip of the charging gun 7, the vertical movement component 2 and the horizontal movement component 4 are controlled, specifically including the following steps:

[0090] Filter out the pressure signals of the first pressure sensors 9 located at both ends of the vertical diameter of the gun head and the pressure signals of the first pressure sensors 9 located at both ends of the horizontal diameter of the gun head;

[0091] The pressure signals of the first pressure sensors 9 at both ends of the vertical diameter that are greater than the second threshold are used as the first parameter; the difference between the first parameter and the second threshold is calculated, and the difference is used as the vertical adjustment parameter;

[0092] The pressure signals of the first pressure sensors 9 at both ends of the transverse diameter that are greater than the second threshold are used as the second parameter; the difference between the second parameter and the second threshold is calculated, and the difference is used as the transverse adjustment parameter;

[0093] The corresponding vertical movement component 2 and horizontal movement component 4 are controlled based on the vertical adjustment parameters and the horizontal adjustment parameters.

[0094] This ensures that once the charging gun muzzle reaches the vehicle's charging port, it can be inserted manually or via telescopic rod 5 after alignment. During this process, the charging gun muzzle may experience resistance from different directions. First pressure sensors 9 in different directions of the charging gun 7 confirm the magnitude and direction of the force applied to the charging gun 7, and then the calibration control unit fine-tunes the insertion angle of the charging gun. After charging is completed, the charging gun is automatically removed via telescopic rod 5.

[0095] In summary, the problem of the heavy total weight of the charging gun and cable making it difficult for people to carry them is completely solved; the problem of the difficulty in calibrating the charging gun and the charging port due to the weight of the charging gun and cable is solved; the problem of difficulty in inserting the charging gun due to the weight of the charging gun and cable and the deviation of the operating angle of the person is solved.
