Description

Technical Field

[0001] The present invention relates to the technical field of automobile charging, and in particular to an automobile charging pile. Background Art

[0002] The function of a car charging pile is similar to that of a gas pump at a gas station. It is a device for charging electric vehicles. It can convert the electrical energy in the power grid into a current and voltage suitable for charging electric vehicle batteries, thereby providing power energy for electric vehicles. Car charging piles are mainly divided into AC charging piles and DC charging piles. AC charging piles output AC power, which is converted into DC power by an on-board charger and then charged to the electric vehicle battery. Its charging speed is relatively slow, and it generally takes several hours to fully charge the electric vehicle battery. It is suitable for use in places where vehicles stay for a long time, such as homes and unit parking lots. DC charging piles directly output DC power to charge electric vehicle batteries without the need for conversion by an on-board charger. Its charging power is large and can replenish a large amount of electricity for electric vehicles in a short time. It is mainly installed in places such as highway service areas and urban public fast charging stations. Vehicles stay in these places for a short time and there is a high demand for quick replenishment of electricity. In order to facilitate users to take it, some existing car charging piles will set a gun holder on the front side of the charging pile, and then insert the charging gun into the gun holder for users to take.

[0003] A Chinese patent document with announcement number CN117124901B discloses a new energy vehicle charging pile, including a column and a charging pile body, wherein the charging pile body is fixedly connected to the column, and the charging pile body is provided with a connecting piece for fixing a charging gun, wherein the connecting piece includes an annular fixing piece, which is fixedly connected to the charging pile body, and a circular receiving groove is provided on the fixing piece, in which a sealing gasket made of rubber material is rotatably installed, and an air cavity is provided inside the sealing gasket, and the charging gun can be slidably fitted in the sealing gasket.

[0004] When in use, the column is fixed to the ground by a mounting plate, and the charging pile body is set on the column. The charging gun is inserted into the sealing gasket during the non-charging period and is sealed by the elastic deformation ability of the rubber sealing gasket itself. In an environment with a temperature below 0 degrees Celsius, the air volume in the air cavity will become smaller due to the influence of low temperature, so that the pressure in the air cavity will decrease. Under the action of external atmospheric pressure, the part constituting the outer wall of the air cavity will shrink toward the air cavity, thereby increasing the inner diameter of the inner ring of the sealing gasket where the air cavity is located, and separating the inner ring of the sealing gasket from the charging gun to prevent freezing from causing the charging gun and the sealing gasket to stick together. In an environment with a temperature below 0 degrees Celsius, the water in the accommodating cavity will freeze, and the volume of the water will expand after freezing, so that the inner diameter of the inner ring of the sealing gasket where the accommodating cavity is located will decrease.

[0005] However, the above patent document still has the following shortcomings: the charging sockets of some electric vehicles are located on the side of the vehicle body near the rear end. After the electric vehicle is parked in the charging position, the rear end of the electric vehicle faces the charging pile. At this time, the charging gun is inserted into the charging socket of the electric vehicle to charge the electric vehicle. After the electric vehicle is charged, the user will insert the charging gun into the gun holder, and some commonly used items are usually stored in the trunk at the rear of the vehicle. When the user passes through the space between the rear end of the vehicle and the charging pile, the charging gun has a certain length, and the user is likely to collide with the charging gun, thereby causing damage to the connection between the charging gun and the gun holder. Summary of the Invention

[0006] The present invention provides a car charging pile, which aims to solve the problem in the related art that when a user passes through the space between the rear of the car and the charging pile, the user is likely to collide with the charging gun due to the certain length of the charging gun, thereby causing damage to the connection between the charging gun and the gun holder.

[0007] The automobile charging pile of the present invention includes a column, a charging mechanism and a placement piece. The charging mechanism includes a connecting line and a charging gun. The placement piece includes a placement frame and a gun seat. It also includes a movable mechanism. The movable mechanism includes a movable part, a mounting seat and a buffer part. The movable part includes a fixed seat, a rotating shaft and an elastic part. The fixed seat is connected to the column, the rotating shaft is connected to the mounting seat, the rotating shaft is rotatably connected to the fixed seat, the elastic part is connected between the mounting seat and the fixed seat, and is used to drive the mounting seat to reset. The gun seat is connected in the mounting seat. The charging gun inserted in the gun seat can rotate along the axis of the rotating shaft after being collided. The buffer part is connected between the rotating shaft and the fixed seat and is used to slow down the resetting speed of the rotating shaft.

[0008] Beneficial effect: When charging an electric car, first park the electric car in front of the car charging pile with the rear end of the electric car facing the car charging pile, then remove the connecting line and the charging gun from the placement piece, and plug the charging gun into the charging socket on the electric car to charge the electric car. After charging is completed, the connecting line is rolled up and hung on the placement rack, and the charging gun is plugged into the gun seat. When the user passes by the rear end of the electric car and collides with the charging gun, the charging gun can drive the gun seat to flip under the action of the rotating shaft to avoid damage to the charging gun after being collided with the user, and at the same time avoid damage to the user after colliding with the charging gun, thereby improving the safety performance of the car charging pile. After the user separates from the charging gun, the charging gun and the gun seat are driven to reset under the action of the elastic part 1, and the buffer part slows down the resetting speed of the charging gun and the gun seat to avoid damage to the charging gun caused by the violent shaking caused by the rapid resetting of the gun seat and the charging gun.

[0009] Preferably, two buffer members are provided, wherein one buffer member can provide damping when the mounting seat is reset to the left, and the other buffer member can provide damping when the mounting seat is reset to the right.

[0010] Preferably, the buffer component includes a buffer structure, a trigger structure and a positioning structure. The buffer structure is connected in the fixed seat, and the buffer structure can be used to damp and buffer the mounting seat when it is reset. The trigger structure is connected between the rotating shaft and the buffer structure. When the rotating shaft rotates, the buffer structure can be triggered by the trigger structure to enable the buffer structure to damp and buffer the mounting seat when it is reset. The positioning structure is connected to the buffer structure.

[0011] Preferably, the buffer structure includes a damping ring, gear 1, a support rod, a mounting portion, a connecting shaft, gear 2 and a one-way bearing, the damping ring is connected in the fixed seat, gear 1 is rotatably connected in the fixed seat, gear 1 is in contact with the damping ring, the support rod is connected to the inner side of the sealing portion, the mounting portion is limitedly slidably connected to the support rod, the connecting shaft is connected to the mounting portion, gear 2 is connected to the connecting shaft through a one-way bearing, and gear 2 is meshed with gear 1 for transmission.

[0012] The effect is that when the charging gun collides with the user and rotates, it drives the rotating shaft to rotate. When the rotating shaft rotates, the trigger structure can trigger the buffer structure, so that the mounting portion in the buffer structure can move on the support rod. At this time, under the action of the one-way bearing, Gear 2 can rotate on the connecting shaft, so that Gear 2 can mesh with Gear 1 when moving on the support rod. Gear 1 remains stationary under the damping of the damping ring, thereby reducing the resistance of the buffer component to the charging gun when the charging gun rotates, ensuring that the charging gun can turn left or right smoothly. After the user separates from the charging gun, the elastic part 1 drives the rotating shaft to gradually reset. At this time, the rotating shaft drives the trigger structure, so that the trigger structure drives the buffer structure to gradually reset, that is, the mounting part drives the connecting shaft, gear 2 and the one-way bearing to move and reset. At this time, under the action of the one-way bearing, gear 2 cannot rotate on the connecting shaft, so that gear 2 can push gear 1 to rotate when the mounting part resets. The friction between gear 1 and the damping ring damps the reset of the rotating shaft, thereby slowing down the reset speed of the charging gun.

[0013] Preferably, the friction force between the gear 1 and the damping ring is smaller than the rebound force of the elastic part 1.

[0014] The effect is that the friction between the gear 1 and the damping ring is smaller than the rebound force of the elastic part 1, so that the gear 1 in contact with the damping ring can rotate under the action of the rebound force of the elastic part 1.

[0015] Preferably, the support rod is arc-shaped and is coaxially arranged with the rotating shaft.

[0016] The effect is that: through the arc-shaped support rod arranged coaxially with the rotating shaft, the mounting part can move along the arc track on the support rod, and the center of the arc track is located on the axis of the rotating shaft, so that gear 2 is always engaged with gear 1.

[0017] Preferably, the trigger structure includes a pushing part, a moving part, a guiding part, a plug-in part and a second elastic part, the pushing part is connected to the rotating shaft, the moving part is connected to the mounting part, the moving part is L-shaped, the guiding part is connected to the inner side of the sealing part, the plug-in part is plugged into the moving part, and the second elastic part is connected between the plug-in part and the moving part.

[0018] The effect is that when the user collides with the charging gun and causes the rotating shaft to rotate, the rotating shaft drives the pushing part to rotate. At this time, the moving part blocks the pushing part so that the pushing part pushes the moving part to move. When the moving part moves, it drives the mounting part to move on the support rod, thereby driving gear 2 and gear 1 to engage and transmit. When the moving part moves, the plug-in part moves toward the direction close to the pushing part under the action of the guide part, so that the plug-in part and the pushing part are plugged in, and the elastic part 2 is compressed, thereby fixing the pushing part and the moving part, so that when the rotating shaft is reset later, the pushing part drives the moving part to move, thereby driving the mounting part to reset, and after the mounting part is reset, the plug-in part is separated from the pushing part.

[0019] Preferably, one end of the guide portion close to the plug-in portion is an inclined surface, the guide portion is arc-shaped, the inner side of the guide portion is an arc-shaped surface, and the guide portion is coaxially arranged with the rotating shaft.

[0020] Preferably, the positioning structure includes a blocking portion, a first magnetic block and a second magnetic block, the blocking portion is connected to an end of the support rod away from the sealing portion, the first magnetic block is connected to the blocking portion, and the second magnetic block is connected to the mounting portion.

[0021] Preferably, the movable mechanism further includes a rotating part and a third elastic part, the gun seat is rotatably connected to the mounting seat via the rotating part, and the third elastic part is connected between the gun seat and the mounting seat.

[0022] The effect is that the gun holder can swing up and down in the mounting seat through the rotating part, so that the user can adjust the angle of holding the charging gun according to his or her height, improving the comfort of the user's wrist when holding the charging gun, and the gun holder is reset by the elastic part.

[0023] The beneficial effects of the present invention are: 1. When a user passes by the rear of an electric vehicle and collides with the charging gun, the charging gun can drive the gun holder to flip under the action of the rotating shaft to avoid damage to the charging gun after the collision with the user. At the same time, it also avoids damage to the user after the collision with the charging gun, thereby improving the safety performance of the car charging pile. After the user separates from the charging gun, the charging gun and the gun holder are reset under the action of the elastic part.

[0024] 2. When the user passes by the rear of the electric vehicle and collides with the charging gun, the rotating shaft is driven to rotate. When the rotating shaft rotates, the trigger structure can trigger the buffer structure, so that the mounting part in the buffer structure can move on the support rod. At this time, under the action of the one-way bearing, gear 2 can rotate on the connecting shaft, so that gear 2 can engage with gear 1 when moving on the support rod, and gear 1 remains stationary under the damping of the damping ring, thereby reducing the resistance of the buffer to the charging gun when the charging gun rotates, ensuring that the charging gun can turn left or right smoothly.

[0025] 3. After the user separates from the charging gun, the elastic part 1 drives the rotating shaft to gradually reset. At this time, the rotating shaft drives the trigger structure, so that the trigger structure drives the buffer structure to gradually reset. That is, the mounting part drives the connecting shaft, gear 2 and one-way bearing to move and reset. At this time, under the action of the one-way bearing, gear 2 cannot rotate on the connecting shaft, so that gear 2 can push gear 1 to rotate when the mounting part resets. The friction between gear 1 and the damping ring damps the reset of the rotating shaft, thereby slowing down the reset speed of the charging gun.

[0026] 4. The rotating part can make the gun holder swing up and down in the mounting base, so that the user can adjust the angle of holding the charging gun according to his or her height, improving the comfort of the user's wrist when holding the charging gun, and the elastic part drives the gun holder to reset.

[0037] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] like Figures 1 to 9 As shown, the car charging pile of the present invention includes a column 1, a charging mechanism 2, a placement piece 3 and a movable mechanism 4. The charging mechanism 2 is connected to the column 1. The charging mechanism 2 can be fixed at a set height through the column 1 for the convenience of the user. The electric car can be charged through the charging mechanism 2. The charging mechanism 2 includes a connecting line 22 and a charging gun 23. The charging gun 23 is connected to the connecting line 22. The placement piece 3 is connected to the column 1. The connecting line 22 and the charging gun 23 can be stored through the placement piece 3 for the convenience of the user to take the charging gun 23 for use. The movable mechanism 4 is connected to the placement piece 3. The charging gun 23 can be deflected after being hit by the user through the movable mechanism 4, thereby avoiding damage to the charging gun 23 after being hit by the user, and at the same time avoiding damage to the user after collision with the charging gun 23, thereby improving the safety performance of the car charging pile.

[0039] When charging an electric vehicle, first park the electric vehicle in front of the car charging pile with the rear end of the electric vehicle facing the car charging pile. Then remove the connecting line 22 and the charging gun 23 placed on the placement piece 3, and insert the charging gun 23 into the charging socket of the electric vehicle to charge the electric vehicle. After charging is completed, remove the charging gun 23 on the electric vehicle, then reel in the connecting line 22 and hang it on the placement piece 3, and plug the charging gun 23 into the placement piece 3. When the user passes through the space between the rear end of the car and the charging pile to take items in the trunk of the electric vehicle, the user collides with the charging gun 23 and can push the charging gun 23. At this time, the charging gun 23 can be flipped under the action of the movable mechanism 4 to avoid damage to the charging gun 23 and at the same time avoid damage to the user after colliding with the charging gun 23, thereby improving the safety performance of the car charging pile.

[0040] like Figure 1 and Figure 2 As shown, the charging mechanism 2 also includes a charging box 21 and a locking piece 24. The charging box 21 is connected to the column 1, and the end of the connecting line 22 away from the charging gun 23 is connected to the charging box 21. The charging box 21 can provide the power required for charging the electric vehicle, so that the charging gun 23 can charge the electric vehicle after being plugged into the charging socket of the electric vehicle. The locking piece 24 is installed on the charging gun 23. When the charging gun 23 is plugged into the charging socket on the electric vehicle, the charging gun 23 can be locked in the charging socket of the electric vehicle through the locking piece 24 to prevent the charging gun 23 from falling from the electric vehicle. When the charging gun 23 is plugged into the placement rack 32, the charging gun 23 can be locked on the placement rack 32 through the locking piece 24 to prevent the charging gun 23 from falling from the placement rack 32.

[0041] When charging an electric vehicle, park the electric vehicle in front of the car charging pile with the rear of the electric vehicle facing the car charging pile. Then remove the connecting line 22 and the charging gun 23 placed on the placement piece 3, and insert the charging gun 23 into the charging socket of the electric vehicle. At the same time, under the action of the locking piece 24, lock the charging gun 23 in the charging socket of the electric vehicle. Then start the charging box 21, and power the charging gun 23 through the charging box 21 to complete the charging operation of the electric vehicle.

[0042] like Figure 1 、 Figure 3 and Figure 4As shown, the placement member 3 includes a connecting plate 31, a placement rack 32 and a gun seat 33. The connecting plate 31 is connected to the column 1, and the placement rack 32 is connected to the connecting plate 31. The placement rack 32 can support the wound connecting line 22. The gun seat 33 is installed on the connecting plate 31. The charging gun 23 can be stored through the gun seat 33. When the charging mechanism 2 is not in use, the wound connecting line 22 is hung on the placement rack 32, and the charging gun 23 is plugged into the gun seat 33. The charging gun 23 is fixed to the gun seat 33 by the locking member 24.

[0043] like Figure 1 、 Figures 3 to 9 As shown, the movable mechanism 4 includes a movable part 41, a mounting seat 42, a buffer part 43 and a sealing part 44. The movable part 41 is connected to the connecting plate 31, the mounting seat 42 is installed on the movable part 41, and the gun seat 33 is installed in the mounting seat 42. The movable part 41 can make the gun seat 33 rotate left or right after receiving an external force, thereby preventing the charging gun 23 from being damaged after the user collides with the charging gun 23, and at the same time preventing the user from being injured after the collision with the charging gun 23, thereby improving the safety performance of the car charging pile, and the user and the charging gun can be kept away from each other. After the charging gun 23 is separated, the gun seat 33 can drive the charging gun 23 to reset through the movable part 41. The buffer part 43 is connected to the movable part 41. The buffer part 43 can slow down the rotation speed of the gun seat 33 when the gun seat 33 drives the charging gun 23 to reset, so as to avoid the violent shaking caused by the rapid reset of the gun seat 33 from causing damage to the charging gun 23. The sealing part 44 is connected to the mounting seat 42, and is used to seal the buffer part 43 in the mounting seat 42, so as to prevent dust in the air from adhering to the buffer part 43 and affecting the use effect of the buffer part 43.

[0044] Continue to refer Figure 1 、 Figures 3 to 9 As shown, the movable part 41 includes a fixed seat 411, a rotating shaft 412 and an elastic part 413. The fixed seat 411 is connected to the connecting plate 31, and the fixed seat 411 is U-shaped. The rotating shaft 412 is rotatably connected to the fixed seat 411. The bottom end of the rotating shaft 412 extends into the fixed seat 411, and the mounting seat 42 is connected to the top of the rotating shaft 412. The elastic part 413 is a torsion spring, and the elastic part 413 is connected between the mounting seat 42 and the fixed seat 411. After the charging gun 23 is hit by the user, the charging gun 23 can drive the gun seat 33 and the mounting seat 42 to swing left or right to avoid damage to the charging gun 23, and the angle at which the charging gun 23 drives the fixed seat 411 and the rotating shaft 412 to rotate left or right is less than 90 degrees.

[0045] Continue to refer Figure 1 、 Figures 3 to 9As shown, two buffer members 43 are provided, wherein one buffer member 43 can damp the mounting seat 42 when it is turned left to reset, and the other buffer member 43 can damp the mounting seat 42 when it is turned right to reset, so as to prevent the mounting seat 42 from driving the gun seat 33 to reset too quickly and causing violent shaking and damage to the charging gun 23. The buffer member 43 includes a buffer structure, a trigger structure and a positioning structure. The buffer structure is connected in the fixing seat 411, and the buffer structure can be used to damp and buffer the mounting seat 42 when it is reset. The trigger structure is connected between the rotating shaft 412 and the buffer structure. When the rotating shaft 412 rotates, the buffer structure can be triggered by the trigger structure, thereby realizing damping and buffering of the mounting seat 42 when it is reset. The positioning structure is connected to the buffer structure, and the buffer structure can be positioned by the positioning structure.

[0046] Continue to refer Figure 1 、 Figures 3 to 9 As shown, the buffer structure includes a damping ring 431, a gear 1 432, a support rod 433, a mounting portion 434, a connecting shaft 435, a gear 2 436 and a one-way bearing 437. The damping ring 431 is connected to the fixing seat 411, the damping ring 431 is sleeved on the outside of the rotating shaft 412 and does not contact the rotating shaft 412. The damping ring 431 is coaxially arranged with the rotating shaft 412, the gear 1 432 is rotatably connected to the fixing seat 411, the gear 1 432 is coaxially arranged with the rotating shaft 412, the gear 1 432 is in contact with the damping ring 431, and the gear 1 432 is in contact with the damping ring 431. 1 is less than the rebound force of the elastic part 1 413, so that the gear 1 432 in contact with the damping ring 431 can rotate under the action of the rebound force of the elastic part 1 413, the support rod 433 is connected to the inner side of the sealing part 44, the support rod 433 is arc-shaped, the support rod 433 is coaxially arranged with the rotating shaft 412, the mounting part 434 is limitedly slidably connected to the support rod 433, the connecting shaft 435 is connected to the mounting part 434, the gear 2 436 is connected to the connecting shaft 435 through a one-way bearing 437, and the gear 2 436 is meshed with the gear 1 432 for transmission.

[0047] After the user collides with the charging gun 23, the charging gun 23 drives the gun seat 33, the mounting seat 42 and the rotating shaft 412 to rotate through the rotating shaft 412, and twists the elastic part 413. At this time, the rotating shaft 412 drives one of the buffer members 43, so that the trigger structure in the buffer member 43 pushes the mounting portion 434 to move, so that the mounting portion 434 moves along an arc trajectory under the support and guidance of the support rod 433, and the center of the arc trajectory is located on the axis of the rotating shaft 412. The mounting portion 434 moves along an arc trajectory. During the rotation of the charging gun 23, the connecting shaft 435, the gear 2 436 and the one-way bearing 437 can be driven to move in an arc shape. At this time, the gear 2 436 can rotate on the connecting shaft 435 under the action of the one-way bearing 437, so that the gear 2 436 is engaged with the gear 1 432 during the rotation along the arc trajectory, and the gear 1 432 remains stationary under the damping of the damping ring 431, thereby reducing the resistance of the buffer member 43 to the charging gun 23 when the charging gun 23 rotates, ensuring that the charging gun 23 can turn left or right smoothly.

[0048] After the user separates from the charging gun 23, the elastic part 1 413 drives the rotating shaft 412 to gradually reset. At this time, the rotating shaft 412 drives the trigger structure, so that the trigger structure drives the buffer structure to gradually reset, that is, the mounting part 434 drives the connecting shaft 435, gear 2 436 and the one-way bearing 437 to move and reset. At this time, under the action of the one-way bearing 437, gear 2 436 cannot rotate on the connecting shaft 435, so that when the mounting part 434 resets, gear 1 432 can be pushed by gear 2 436 to rotate. The friction between gear 1 432 and the damping ring 431 damps the reset of the rotating shaft 412, thereby slowing down the reset speed of the charging gun 23.

[0049] Continue to refer Figure 1 、 Figures 3 to 9As shown, the trigger structure includes a pushing portion 438, a moving portion 439, a guide portion 4310, a plug-in portion 4311 and an elastic portion 4312. The pushing portion 438 is connected to the rotating shaft 412, and the moving portion 439 is connected to the mounting portion 434. The moving portion 439 is L-shaped and is used to block the pushing portion 438 in one direction. The blocking directions of the moving portions 439 in the trigger structures on the two buffer members 43 are opposite. After the user collides with the charging gun 23, when the charging gun 23 turns left or right and drives the rotating shaft 412 to rotate, only the buffer structure on the corresponding buffer member 43 can operate. The guide portion 4310 is connected to the inner side of the sealing portion 44, and the plug-in portion 4311 is plugged into the moving portion 439. The second elastic part 4312 is connected between the plug-in part 4311 and the movable part 439. The second elastic part 4312 is a compression spring, which is used to drive the plug-in part 4311 to reset. The end of the guide part 4310 close to the plug-in part 4311 is an inclined surface, which is used to guide the plug-in part 4311 so that when the movable part 439 passes through the inclined surface, the movable part 439 can move toward the direction close to the pushing part 438 to enable the plug-in part 4311 to be plugged into the pushing part 438. The guide part 4310 is arc-shaped, and the inner side of the guide part 4310 is an arc-shaped surface. The guide part 4310 is coaxially arranged with the rotating shaft 412, and the arc-shaped surface on the inner side of the guide part 4310 is used to keep the plug-in part 4311 in a state of being plugged into the pushing part 438.

[0050] When the rotating shaft 412 rotates due to the collision between the user and the charging gun 23, the rotating shaft 412 triggers one of the buffer members 43, so that the rotating shaft 412 drives the pushing portion 438 on the buffer member 43 to rotate. At this time, the moving portion 439 blocks the pushing portion 438, so that the pushing portion 438 pushes the moving portion 439 to move. When the moving portion 439 moves, it drives the mounting portion 434 to move on the support rod 433, thereby driving the second gear 436 to engage with the first gear 432 for transmission. When the moving portion 439 moves, the plug-in portion 4311 moves toward the direction close to the pushing portion 438 under the action of the guide portion 4310, so that the plug-in portion 4311 is plugged into the pushing portion 438 and compresses the second elastic portion 4312, thereby fixing the pushing portion 438 and the moving portion 439. When the user separates from the charging gun 23 and the rotating shaft 412 is reset under the action of the elastic part 413, the pushing part 438 rotates and resets. At this time, under the action of the plug-in part 4311, the pushing part 438 is fixed to the moving part 439, so that the pushing part 438 pulls the moving part 439 to reset and move, thereby driving the mounting part 434 to move and reset through the moving part 439. When the mounting part 434 moves and resets, the gear 1 432 is pushed to rotate through the gear 2 436. The friction force between the gear 1 432 and the damping ring 431 provides resistance to the rotation reset of the rotating shaft 412, thereby providing a buffer for the reset of the charging gun 23 until the buffer member 43 is completely reset.

[0051] Continue to refer Figure 1 、 Figures 3 to 9 As shown, the positioning structure includes a blocking portion 4313, a magnet 1 4314 and a magnet 2 4315. The blocking portion 4313 is connected to one end of the support rod 433 away from the sealing portion 44. The blocking portion 4313 can prevent the mounting portion 434 from falling off the support rod 433. The magnet 1 4314 is connected to the blocking portion 4313, and the magnet 2 4315 is connected to the mounting portion 434. The magnet 1 4314 can be magnetically attracted to the magnet 2 4315, thereby positioning the mounting portion 434.

[0052] Continue to refer Figure 1 、 Figures 3 to 9 As shown, the movable mechanism 4 also includes a rotating portion 45 and an elastic portion 3 46. The gun seat 33 is rotatably connected to the mounting seat 42 via the rotating portion 45. The rotating portion 45 enables the gun seat 33 to swing up and down in the mounting seat 42, so that the user can adjust the angle of holding the charging gun 23 according to his or her height, thereby improving the comfort of the user's wrist when holding the charging gun 23. The elastic portion 3 46 is connected between the gun seat 33 and the mounting seat 42. The elastic portion 3 46 is a torsion spring, which is used to drive the gun seat 33 to reset.

[0053] Working principle: When charging an electric vehicle, first park the electric vehicle in front of the car charging pile with the rear of the electric vehicle facing the car charging pile. Then remove the connecting line 22 and the charging gun 23 placed on the placement piece 3, and insert the charging gun 23 into the charging socket of the electric vehicle. At the same time, under the action of the locking piece 24, the charging gun 23 is locked in the charging socket of the electric vehicle. Then start the charging box 21, and power the charging operation of the charging gun 23 through the charging box 21, thereby completing the charging operation of the electric vehicle. After charging is completed, unplug the charging gun 23 from the charging socket of the car, then reel up the connecting line 22 and hang it on the placement rack 32, and finally plug the charging gun 23 into the gun seat 33 and lock it with the locking piece 24.

[0054] When the user passes through the space between the rear of the car and the charging pile to take items in the trunk of the electric car, the user collides with the charging gun 23 and pushes the charging gun 23, and drives the gun seat 33, the mounting seat 42 and the rotating shaft 412 to rotate through the rotating shaft 412, and twists the elastic part 413 to buffer the charging gun 23. At this time, the rotating shaft 412 triggers one of the buffer parts 43, so that the rotating shaft 412 drives the pushing part 438 on the buffer part 43 to rotate. At this time, the moving part 439 blocks the pushing part 438, so that the pushing part 438 pushes the moving part 439 to move. When the moving part 439 moves, it drives the mounting part 434 to move on the support rod 433. During the movement of the mounting part 434 In the process, the connecting shaft 435, the gear 2 436 and the one-way bearing 437 are driven to move. At this time, the gear 2 436 can rotate on the connecting shaft 435 under the action of the one-way bearing 437, so that the gear 2 436 engages with the gear 1 432 during the movement along the arc trajectory, and the gear 1 432 remains stationary under the damping of the damping ring 431, ensuring that the charging gun 23 can turn left or right smoothly. When the moving part 439 moves, the plug-in part 4311 moves toward the direction close to the pushing part 438 under the action of the guide part 4310, so that the plug-in part 4311 is plugged into the pushing part 438, and the elastic part 2 4312 is compressed, thereby fixing the pushing part 438 and the moving part 439.

[0055] After the user separates from the charging gun 23, when the rotating shaft 412 is reset under the action of the elastic part 413, the pushing part 438 rotates and resets. At this time, under the action of the plug-in part 4311, the pushing part 438 is fixed to the moving part 439, so that the pushing part 438 pulls the moving part 439 to reset and move, thereby driving the mounting part 434 to move and reset through the moving part 439. At this time, under the action of the one-way bearing 437, gear 2 436 cannot rotate on the connecting shaft 435, so that when the mounting part 434 resets and moves, gear 2 436 can push gear 1 432 to rotate, and the friction force between gear 1 432 and the damping ring 431 damps the reset of the rotating shaft 412, thereby providing a buffer for the reset of the charging gun 23 until the buffer member 43 and the charging gun 23 are completely reset.
