Description
Technical Field
[0001] The present invention relates to the technical field of vehicle charging piles, and particularly to a cable detachment protection mechanism for a vehicle charging pile. Background Art
[0002] A charging pile refers to an energy charging device that provides charging services for electric vehicles. It is mainly divided into floor-mounted charging piles and wall-mounted charging piles, and mainly adopts charging methods based on time, electricity consumption, and amount. Its function is similar to that of a fuel dispenser in a gas station. It can be fixed on the ground or wall, installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential community parking lots or charging stations, and can charge various models of electric vehicles according to different voltage levels.
[0003] After the electric vehicle is fully charged, if the plug is forgotten to be detached from the electric vehicle, the pulling force during the movement of the electric vehicle will break the cable. In the existing device, a protection device is provided to automatically detach the plug from the electric vehicle when the vehicle moves, preventing the cable from being damaged. However, in reality, pedestrians or passing carts may accidentally pull the cable, but the pulling force on the cable is not very large and will not cause damage. At this time, after the cable is tightened, if the protection device is triggered to disconnect the plug, then the plug still needs to be reconnected to the electric vehicle later, which may consume too much charging time and cause inconvenience to the vehicle owner. Summary of the Invention
[0004] In order to solve the above problems, the present invention provides a cable detachment protection mechanism for a vehicle charging pile.
[0005] The present invention adopts the following technical solutions. A cable detachment protection mechanism for a vehicle charging pile includes a charging head and a suction cup fixedly connected to the outer wall of the charging head plug. A fixed frame is fixedly connected to the outer wall of the charging head plug on one side of the suction cup. The outer wall of the charging head is wrapped with elastic rubber, and further includes:
[0006] An auxiliary mechanism, which is used to prevent the detachment of the suction cup and also to separate the suction cup from the vehicle in a timely manner. The auxiliary mechanism is arranged in the suction cup;
[0007] An identification mechanism, which is used to identify whether the vehicle starts. The identification mechanism is arranged in the fixed frame;
[0008] And a pop-up mechanism, which can move the entire device away from the vehicle when the vehicle moves. The pop-up mechanism is arranged in the charging head.
[0009] As a further description of the above technical solution: The auxiliary mechanism includes an insertion ring movably arranged inside the suction cup, and the insertion ring abuts against the inner wall of the suction cup.

A slider is rotatably arranged at the upper end of the inner cavity of the fixed frame. An air hole is opened at the center of the upper end of the fixed frame. A conduit is communicated between the inner cavity of the suction cup and the inner cavity of the fixed frame.
[0010] As a further description of the above technical solution: The identification mechanism includes a suspension cord fixedly connected to the bottom end of the slider, and an iron ball is fixedly connected to the bottom end of the suspension cord. Springs three are fixedly connected between the two opposite ends of the slider and the fixed frame respectively.

[0011] As a further description of the above technical solution: The ejection mechanism includes a sleeve ring. A spring five is fixedly connected between one end of the sleeve ring away from the suction cup and the charging head. An elevating plate is arranged to slide up and down in the charging head below the iron ball, and a spring six is fixedly connected between the bottom end of the elevating plate and the charging head.

[0017] First, if the driver forgets to remove the charging head from the car and drives away, the magnetic block will absorb the iron ball. When the slider rotates to the maximum distance, the slider and the air hole are offset, so that the outside air enters the inner cavity of the suction cup through the air hole and the conduit, so that the suction cup is separated from the car. Through the cooperation of the magnetic block and the iron ball, the charging head can be separated from the car when the car is started without using electrical appliances, preventing pedestrians or passing carts from accidentally pulling the cable and separating the charging head from the car, so that the plug needs to be reconnected to the electric car later, which may consume too much charging time and cause inconvenience to the car owner.
[0018] Second: When the car is not started, if pedestrians or passing carts pull the cable connecting the charging head and the charging pile, the movement of the plug ring will be blocked. If the plug ring moves away from the car, the pressure in the suction cup cavity will continue to decrease, and the suction cup and the car will be more firmly attached.
[0019] Third: Through the setting of the pop-up mechanism, the charging head can be instantly popped outward, quickly moving the charging head away from the car to prevent the charging head from scratching the car when the car moves, and also to prevent the charging head from falling to the ground and being crushed by the car;
[0020] To sum up, through the cooperation of the magnetic block and the iron ball, the charging head can be detached from the car only when the car is started without the use of electrical appliances, thereby preventing the charging head from being detached from the car when pedestrians or people pushing the carts accidentally pull the cable, so that the plug needs to be reconnected to the electric car later, which may take too much charging time and cause inconvenience to the car owner. Through the setting of the pop-up mechanism, the charging head can be instantly popped outward and quickly moved away from the car to prevent the charging head from scratching the car when the car moves, and can also prevent the charging head from falling to the ground and being crushed by the car.

Detailed implementation manners
[0031] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below with reference to specific drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0032] Please refer to Figure 1 - Figure 8 , the embodiment of the present invention provides a technical solution: a cable detachment protection mechanism for an electric vehicle charger, including a charger head 1 and a suction cup 2 fixedly connected to the outer wall of the plug of the charger head 1. On one side of the suction cup 2, a fixed frame 3 is fixedly connected to the outer wall of the plug of the charger head 1. The outer wall of the charger head 1 is wrapped with elastic rubber, and further includes:
[0033] An auxiliary mechanism 5, which is used to prevent the suction cup 2 from falling off and also to separate the suction cup 2 from the vehicle in time. The auxiliary mechanism 5 is arranged in the suction cup 2;
[0034] An identification mechanism 6, which is used to identify whether the vehicle has started. The identification mechanism 6 is arranged in the fixed frame 3;
[0035] And an ejection mechanism 7, which can move the whole device away from the vehicle when the vehicle moves. The ejection mechanism 7 is arranged in the charger head 1.
[0036] Specifically, when the vehicle is not started, if pedestrians or tools such as passing carts pull the cable connecting the charging head 1 and the charging pile, the movement of the plug ring 51 is blocked, and if the plug ring 51 moves away from the vehicle, the pressure in the inner cavity of the suction cup 2 will continue to decrease, so that the suction cup 2 and the vehicle are more firmly attached;
[0037] If the driver forgets to remove the charging head 1 from the vehicle and drives away, the magnetic block 68 will absorb the iron ball 61. When the slider 65 rotates to the maximum distance, the slider 65 and the air hole 54 are staggered, so that the outside air enters the inner cavity of the suction cup 2 through the air hole 54 and the conduit 4, so that the suction cup 2 is separated from the vehicle. Through the cooperation of the magnetic block 68 and the iron ball 61, the charging head 1 can be separated from the vehicle only when the vehicle is started without using electrical appliances, so as to prevent pedestrians or passing carts from accidentally pulling the cable and separating the charging head 1 from the vehicle, so that the plug needs to be reconnected to the electric vehicle later, which may consume too much charging time and cause inconvenience to the owner.
[0038] By setting the pop-up mechanism 7, the charging head 1 can be instantly popped outward and quickly moved away from the car to prevent the charging head 1 from scratching the car when the car moves, and to prevent the charging head 1 from falling to the ground and being crushed by the car.
[0039] In another embodiment provided by the present invention, the auxiliary mechanism 5 includes an insert ring 51 movably arranged in the suction cup 2, and the insert ring 51 is in contact with the inner wall of the suction cup 2, one end of the insert ring 51 close to the fixed frame 3 is fixedly connected with a connecting rod 53, and the connecting rod 53 is movably inserted in the suction cup 2, and the other end of the connecting rod 53 is fixedly connected to the fixed frame 3, the suction cup 2 is slidably arranged on the outer wall of the charging head 1, and a spring 52 is fixedly connected between the end of the suction cup 2 slidably arranged in the charging head 1 and the charging head 1, a slider 65 is rotatably arranged on the upper end of the inner cavity of the fixed frame 3, an air hole 54 is opened at the center of the upper end of the fixed frame 3, and a conduit 4 is connected between the inner cavity of the suction cup 2 and the inner cavity of the fixed frame 3.
[0040] The identification mechanism 6 includes a hanging rope 64 fixed to the bottom end of the slider 65, and an iron ball 61 is fixed to the bottom end of the hanging rope 64. The two opposite ends of the slider 65 are fixed to the fixed frame 3 with springs 3 69. The two opposite sides of the bottom end of the slider 65 are in contact with a shift block 67, and a rotating rod 66 is sleeved on the outer side of the shift block 67. The rotating rod 66 is rotatably set in the inner cavity of the fixed frame 3. A spring 4 610 is fixed between the bottom end of the shift block 67 and the rotating rod 66. The outer wall of the rotating shaft of the rotating rod 66 is wrapped with a pull rope 613, and the pull rope 61 The other end is fixed to the shift block 67, a torsion spring 611 is fixedly connected between the outer wall of the rotating shaft of the rotating rod 66 and the fixed frame 3, a moving ring 62 is movably inserted into the end of the charging head 1 close to the suction cup 2, and a sleeve ring 71 is movably sleeved on the outer side of the end of the moving ring 62 located in the charging head 1, and a spring 2 63 is fixedly connected between the end of the moving ring 62 located in the sleeve ring 71 and the sleeve ring 71, a trapezoidal pressing block 612 is abutted on one side of the rotating rod 66, and the trapezoidal pressing block 612 is fixedly connected to the outer wall of the moving ring 62.
[0041] The guide tube 4 is communicated with the sliding groove where the sliding block 65 is located.
[0042] When the iron ball 61 is located at the center of the inner cavity of the fixed frame 3 , the iron ball 61 will not be attracted by the magnetic block 68 . When the iron ball 61 rotates to the vicinity of the magnetic block 68 , the iron ball 61 will not be immediately adsorbed to the magnetic block 68 .
[0043] Specifically, when the vehicle is not started, if pedestrians or tools such as passing carts pull the cable connecting the charging head 1 and the charging pile, the movement of the plug ring 51 is blocked, and if the plug ring 51 moves away from the vehicle, the pressure in the inner cavity of the suction cup 2 will continue to decrease, so that the suction cup 2 and the vehicle are more firmly attached;
[0044] If the driver forgets to remove the charging head 1 from the vehicle and drives away, the magnetic block 68 will absorb the iron ball 61. When the slider 65 rotates the maximum distance, the slider 65 and the air hole 54 are offset, allowing the outside air to enter the inner cavity of the suction cup 2 through the air hole 54 and the conduit 4, so that the suction cup 2 is separated from the vehicle. Through the cooperation of the magnetic block 68 and the iron ball 61, the charging head 1 can be separated from the vehicle when the vehicle is started without using electrical appliances, thereby preventing pedestrians or passing carts from accidentally pulling the cable and separating the charging head 1 from the vehicle, so that the plug needs to be reconnected to the electric vehicle later, which may consume too much charging time and cause inconvenience to the owner.
[0045] In another embodiment provided by the present invention, the pop-up mechanism 7 includes a ring 71, and a spring five 72 is fixedly connected between the end of the ring 71 away from the suction cup 2 and the charging head 1, a lifting plate 73 is provided on the lower side of the iron ball 61 in the charging head 1 for sliding up and down, and a spring six 74 is fixedly connected between the bottom end of the lifting plate 73 and the charging head 1, trapezoidal blocks 75 are inserted into the upper and lower outer walls of the ring 71, and a spring seven 76 is fixedly connected between the bottom end of the trapezoidal block 75 and the ring 71, a pressure rod 77 is fixedly connected to the bottom end of the shift block 67, and the pressure rod 77 is inserted in the rotating rod 66, and an extrusion block 78 is fixedly connected to the center of the bottom end of the slider 65.
[0046] The squeezing block 78 can enable the shifting block 67 to drive the pressing rod 77 to press the lifting plate 73 downward.
[0047] A plurality of springs 1 52 , 2 63 and 5 72 are arranged in a ring shape at equal intervals.
[0048] Specifically, by setting the pop-up mechanism 7, the charging head 1 can be instantly popped outward, and the charging head 1 can be quickly moved away from the car to prevent the charging head 1 from scratching the car when the car moves, and can also prevent the charging head 1 from falling to the ground and being crushed by the car.
[0049] Working principle: When charging the car, first connect the plug of the charging head 1 to the socket of the new energy car. During the connection, the suction cup 2 is squeezed with the car, and then the suction cup 2 connects the charging head 1 and the car together. When the car is not started, if pedestrians or tools such as passing carts pull the cable connecting the charging head 1 and the charging pile, the charging head 1 will tend to move away from the vehicle. At this time, the charging head 1 will drive the fixing frame 3 and the connecting rod 53 to move away from the suction cup 2, so that the plug ring 51 tends to move away from the car. However, due to the interference between the plug ring 51 and the inner wall of the suction cup 2, the movement of the plug ring 51 is blocked, and if the plug ring 51 moves in the direction away from the car, the pressure in the inner cavity of the suction cup 2 will continue to decrease, so that the suction cup 2 and the car are more firmly adsorbed;
[0050] If the driver forgets to remove the charging head 1 from the car and drives the car, the moment the car starts, the charging head 1 and the fixed frame 3 will move immediately. Since the new energy gun is basically connected to the charging port on the side of the car in a positive direction, the iron ball 61 swings relative to the fixed frame 3 due to inertia at the moment the car starts. When the iron ball 61 swings to the position closest to the magnetic block 68, the magnetic block 68 will adsorb the iron ball 61, so that the iron ball 61 drives the slider 65 to rotate to one side. The closer the distance between the iron ball 61 and the magnetic block 68, the greater the suction force of the magnetic block 68 on the iron ball 61. When the slider 65 rotates the maximum distance, the slider 65 is staggered with the air hole 54, so that the outside air enters the inner cavity of the suction cup 2 through the air hole 54 and the conduit 4, so that the suction cup 2 is separated from the car;
[0051] Meanwhile, the extrusion block 78 presses the dial block 67 downward, enabling the pressure lever 77 to press the dial block 67 downward, causing the dial block 67 to move the lifting plate 73 downward through the pressure lever 77, thereby pressing the trapezoidal block 75 into the collar 71. The elastic force of the fifth spring 72 pops the collar 71 and the moving ring 62 outward, so that the charger head 1 can be instantly popped outward, quickly moving the charger head 1 away from the vehicle, preventing the charger head 1 from rubbing against the vehicle when the vehicle moves, and also preventing the charger head 1 from being crushed by the vehicle after falling to the ground;
[0052] After the pop-up, press the moving ring 62 into the charger head 1, so that the collar 71 is re-locked in the initial position. When the moving ring 62 is compressed inward, the moving ring 62 moves and rotates the tops of the two side rotating rods 66 toward each other through the trapezoidal pressing block 612, so that the slider 65 moves back to its original position, and the iron ball 61 also separates from the magnet block 68. When the rotating rod 66 and the dial block 67 rotate, the dial block 67 is gradually pulled downward by the pull rope 613, and finally the dial block 67 is located below the slider 65 to prevent hindering the rotation of the slider 65 when triggering the recognition mechanism 6.
[0053] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The descriptions in the above embodiments and the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
