Description

Technical Field

[0001] This invention relates to new energy vehicle technology, specifically to a new energy vehicle charging gun socket that facilitates plugging and unplugging of the charging gun. Background Technology

[0002] A charging station is a power replenishment device for electric vehicles, similar in function to a gas pump at a gas station. Installed in public buildings (charging stations, shopping malls, public parking lots, etc.) and residential parking lots, it can charge various models of electric vehicles by adjusting the voltage and current. The input end of the charging station is directly connected to the AC power grid, and the output end is equipped with a charging gun for charging electric vehicles.

[0003] The charging gun holder is the carrier of the charging gun. It supports the charging gun and protects its ends when it is not in operation. It is usually connected and fixed by the cooperation between the interface and the buckle. When removing it, the operator needs to press the unlock button and pull the charging gun outward to take it out for use. After use, the operator aligns the port of the charging gun with the interface of the charging gun holder and inserts the charging gun into the interface to complete the reset of the charging gun.

[0004] However, in practical applications, to prevent external factors such as water and dust from entering the charging port, corresponding sealing units are usually installed at the charging gun and the charging port. This results in greater resistance when inserting or removing the charging gun. In addition, the charging gun and charging cable are heavy, especially for fast charging stations, requiring the operator to exert more force when inserting or removing them. Furthermore, in winter, the charging gun and charging cable become stiff due to the low temperature, further increasing the resistance when inserting or removing the charging gun, making its use inconvenient.

[0021] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0022] Example 1: Please see Figures 1-6 A charging gun holder for new energy vehicles that facilitates plugging and unplugging of the charging gun includes a charging base 1 and a charging gun 101 connected to the charging base 1. The charging base 1 is provided with a mating interface 102 adapted to the charging gun 101. The charging base 1 is provided with a controller 103. A translation groove 2 is opened on the side of the charging base 1. A translation seat 21 is slidably connected to the inner side of the translation groove 2. A support seat 22 is installed on the top of the translation seat 21. An entry groove 23 is opened on the side of the support seat 22. A first electric telescopic rod 24 is installed inside the translation groove 2. The support 22 is provided with a clamping unit, which is used to clamp and fix the charging gun 101 placed into the inlet slot 23.

[0023] It should be added that the telescopic end of the first electric telescopic rod 24 is fixedly connected to the translation seat 21. When the telescopic end of the first electric telescopic rod 24 extends or retracts, it can drive the translation seat 21 to perform horizontal reciprocating motion.

[0024] The specific structure of the clamping unit is described below. The clamping unit includes a moving groove 3 opened in the translation seat 21. The moving block 31 is slidably connected to the inner side of the moving groove 3. A second electric telescopic rod 32 is installed inside the moving groove 3. The bottom surface of the bearing seat 22 is provided with a receiving groove that communicates with the entry groove 23. The inner walls of the receiving groove are symmetrically provided with guide grooves 33 extending to the entry groove 23. A clamping block 34 is slidably connected between the two guide grooves 33.

[0025] Furthermore, the bottom of the clamping block 34 is connected to the moving block 31, and the telescopic end of the second electric telescopic rod 32 is fixedly connected to the moving block 31.

[0026] It should be noted that a control button is provided on the side of the charging base 1 above the interface 102. This button is electrically connected to the controller 103. During use, by pressing the button, the controller 103 controls the first electric telescopic rod 24 to start. If the telescopic end of the first electric telescopic rod 24 is in the extended state, when the button is pressed, the clamping unit starts to clamp and fix the charging gun 101, and then it retracts. When the telescopic end of the first electric telescopic rod 24 is in the retracted state, when the button is pressed, it extends. After the extension and retraction is completed, the clamping unit starts and releases the clamp on the charging gun 101. The single extension or retraction stroke of the telescopic end of the first electric telescopic rod 24 is fixed.

[0027] During use, when it is necessary to pull out the charging gun 101, the first electric telescopic rod 24 extends and drives the translation seat 21 to move. The movement of the translation seat 21 drives the carrier seat 22 to move. The movement of the carrier seat 22 drives the charging gun 101 to move away from the charging seat 1, thereby driving the charging gun 101 to exit from the interface 102. At this time, the operator can directly take out the gun for use. After the charging gun 101 is used, the operator places the charging gun 101 into the inlet slot 23. Then, the telescopic end of the second electric telescopic rod 32 extends outward and drives the clamping block 34 to move, which pushes the charging gun 101 to move and presses it into the inlet slot 23, thereby stabilizing the charging gun 101. Afterward, the telescopic end of the first electric telescopic rod 24 retracts and drives the carrier 22 to move closer to the charging base 1, so that the end of the charging gun 101 can be inserted into the interface 102, completing the storage of the charging gun 101.

[0028] Example 2: Please see Figures 3-7 This embodiment provides a technical solution based on the above embodiments: the charging gun 101 includes a gun body 4, a hand grip 41 is provided at the lower end of the gun body 4, a calibration straight part 42 is provided at the upper end of the hand grip 41, a docking end 43 is provided at the end of the gun body 4, and a calibration section 44 is provided between the docking end 43 and the gun body 4.

[0029] It should be noted that the cross-sectional shape of the calibration section 42 is rectangular, and the surface of the calibration section 44 is set flat.

[0030] In this embodiment, a calibration mechanism is provided on the support base 22. The calibration mechanism includes a fixed wheel 5 rotatably disposed on one side of the entry groove 23. A guide portion 514 is provided on the outer end of the fixed wheel 5. A movable wheel 51 corresponding to the fixed wheel 5 is rotatably connected inside the movable groove 3. A calibration groove 52 corresponding to the calibration section 44 is opened on the top of the support base 22. Distance sensors 53 are provided at both the front and rear ends of the bottom of the calibration groove 52. A side seat 54 is provided on the side of the support base 22. An installation groove is opened on the inner side of the side seat 54. A first [missing information] is installed inside the installation groove. Motor 55, the output shaft of the first motor 55 is fixedly connected to the fixed wheel 5, a bracket 56 is slidably connected inside the mounting groove, a second motor 57 is mounted on the bracket 56, the bracket 56 is fixedly connected to the clamping block 34, the output shaft of the second motor 57 is fixedly connected to the moving wheel 51, a connecting seat 58 is slidably connected to the top of the translation seat 21, a buffer groove 59 is opened inside the connecting seat 58, a connecting plate 510 is slidably connected to the inner side of the buffer groove 59, the connecting plate 510 is fixedly connected to the bottom of the clamping block 34, and the bottom of the connecting seat 58 is fixedly connected to the moving block 31.

[0031] It should be noted that the position of the guide section 514 corresponds to the calibration straight section 42. After the charging gun 101 is positionally corrected, one side of the calibration straight section 42 contacts the guide end of the guide section 514, and the other side contacts the inner wall of the inlet groove 23. Furthermore, the calibration section 44 is fitted inside the calibration groove 52.

[0032] Furthermore, a pressure sensor 511 is installed on the inner wall of the buffer groove 59 away from the moving wheel 51, a pressure plate 512 is slidably connected to the inner side of the buffer groove 59, and a pressure spring 513 is installed between the pressure plate 512 and the connecting plate 510.

[0033] It should be noted that the ranging sensor 53, pressure sensor 511, first motor 55, second motor 57, first electric telescopic rod 24, and second electric telescopic rod 32 are all electrically connected to the controller 103.

[0034] When the charging gun 101 is finished using and needs to be returned to its original position, the operator inserts the handle 41 and the calibration straight part 42 of the charging gun 101 into the entry groove 23, inserting it as deep as possible into the entry groove 23. When the operator releases it, the charging gun 101 is easily tilted up under the weight of the charging cable. At this time, the connecting seat 58 and the clamping block 34 are driven by the second electric telescopic rod 32 to move closer to the fixed wheel 5. When the clamping block 34 moves to the point where the moving wheel 51 contacts both sides of the charging gun 101, the connecting seat 58 continues to move, causing relative movement between it and the clamping block 34. At this time, the pressure spring 513 is compressed and applies gradually increasing pressure to the clamping block 34, so that the moving wheel 51 and the fixed wheel 5 can stably clamp it. In addition, during the process, when a part of the charging gun 101 contacts the guide part 514, under the guidance of the guide part 514, the charging gun 101 can move towards the inner wall of the entry groove 23 until it moves to the designated position. When the moving wheel 51 and the fixed wheel 5 are stably distributed on both sides of the charging gun 101, the first motor 55 and the second motor 57 rotate synchronously with the fixed wheel 5 and the moving wheel 51 to transport the charging gun 101 downwards until it can no longer move. Then, the horizontal state of the calibration section 44 is detected by the distance sensor 53. Based on the actual detected data, the controller 103 controls the first motor 55 and the second motor 57 to drive the fixed wheel 5 and the moving wheel 51 to rotate in coordination. This allows the actual state of the charging gun 101 to be adjusted. After the adjustment is completed, it is driven to move downwards until the calibration section 44 is in contact with the calibration groove 52, thus completing the state correction of the charging gun 101. Afterwards, the charging gun 101 is driven to move towards the charging base 1 by the first electric telescopic rod 24, so that the docking end 43 on the charging gun 101 can be accurately inserted into the docking interface 102.

[0035] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
