Description

A self-locking device for new energy charging pile

Technical Field

The present invention relates to the technical field of new energy charging piles, and in particular to a self-locking device for a new energy charging pile.

Background Art

With the development and popularization of electric vehicle technology, the demand for charging infrastructure has increased dramatically. The self-locking device can ensure that the connection between the charging gun and the car is firm during the charging process, thereby improving the safety and reliability of charging. If the charging gun is loose or poorly connected during charging, it may cause charging failure or electrical failure. The self-locking device prevents the charging gun from being accidentally unplugged during charging through mechanical locking or electronic control, reducing safety hazards caused by poor connection. Since the self-locking device reduces failures caused by looseness, it can reduce the maintenance cost and operational risk of charging piles. Stable connection can extend the service life of the equipment and reduce the frequency of maintenance.

The charging cables of existing charging piles are generally exposed. Since there is no reeling device for the charging cables, when the vehicle is charging, the charging cables are too long and passers-by can easily trip over them, posing a certain safety hazard. In addition, the charging gun of the charging pile is generally placed in a fixed storage compartment and fixed to the charging pile by a buckle. However, under the action of large external forces and after long-term use, the locking effect is relatively general and the buckle is easily damaged, causing the charging gun to fall off.

The placement compartment 3 is provided with a charging gun locking mechanism 11 , and the head of the charging gun 4 is provided with a clamping block 12 , and the charging gun locking mechanism 11 cooperates with the clamping block 12 to be self-lockingly fixed.

The working principle of the present invention is as follows: the charging cable 5 is wound and placed on the charging cable winding self-locking mechanism 8, and is electrically connected to the electrical quick-connect wire 6. When the charging pile is idle and does not need to charge the vehicle, the charging gun 4 is placed in the placement compartment 3, and the charging gun 4 is fixed on the charging pile 2 through the charging gun locking mechanism 11 to achieve self-locking fixation; when the vehicle needs to be charged, the charging gun 4 is pulled out of the placement compartment 3, and the charging cable 5 is pulled.

The fixing head 85 is provided with a pair of protruding soft elastic plates. After the soft elastic plates slide through the rotating cylinder 861, they contact with the outer wall of the fixed cylinder 868, thereby fixing the fixed cylinder 868 with the rotating cylinder 861. A connecting cylinder 869 is fixed to the front side of the fixed cylinder 868. A transmission wheel 8610 is sleeved and fixed on the connecting cylinder 869. A rotating shaft 89 is provided on the fixed plate 81. A locking wrench unit 810 which cooperates with the roller unit 86 to fix it is rotatably provided on the rotating shaft 89. The locking wrench unit 810 includes a rotating handle 8101 rotatably arranged on the rotating shaft 89. The rotating handle A pair of connecting ear plates 8102 are provided at the bottom end of 8101, an annular baffle plate 8103 is provided on the fixed plate 81, a limit head 8104 is provided on the top of the annular baffle plate 8103, a rotating wheel 8105 located between the turntable 863 and the limit head 8104 is rotatably provided between the connecting ear plates 8102, the rotating wheel 8105 is frictionally connected with the limit head 8104, and is rotatably connected with the turntable 863, and the gap between the turntable 863 and the limit head 8104 is diffusely arranged from small to large, and a movable groove is reserved on the top surface of the protective box 7, the top end of the rotating handle 8101 passes through the movable groove and is slidably connected thereto, and a contraction spring 8106 is fixedly connected between the movable groove and the rotating handle 8101.

The working principle of locking the fixed length and automatic winding of the charging cable 5 is as follows: dragging the charging gun 4 causes the charging cable 5 to extend. Since the charging cable 5 is wound around the winding drum 862, the winding drum 862 will be driven to rotate around the rotating rod 84. During this process, the clamping block 864 arranged on the winding drum 862 is clamped and fixed with the mainspring 88, so the mainspring 88 will be wound and tightened, and the turntable 863 on the winding drum 862 is rotationally connected to the rotating wheel 8105, so when the turntable 863 rotates, it will drive the rotating wheel 8105 to rotate. Under the action of friction, it will drive the rotating handle 8101 to rotate around the rotating shaft 89. Stop pulling the charging cable 5, and the mainspring 88 will cause the winding drum 862 to rotate in the opposite direction. However, since the limit head 8104 is in friction with the rotating wheel 8105 and is tightly attached, the turntable 863 rotationally connected to the rotating wheel 8105 will not rotate, thereby realizing the self-locking fixation of the charging cable 5 at a certain fixed length. When the charging cable 5 needs to be reeled in, the rotating handle 8101 is turned, and the contraction spring 8106 contracts accordingly. The rotating handle 8101 rotates to drive the rotating wheel 8105 to move and disengage from the turntable 863. Then, under the action of the spring 88, the turntable 863 drives the winding drum 862 to rotate, and the charging cable 5 is wound and reeled in, thereby realizing automatic reeling of the charging cable 5.

As shown in Figures 4, 11 and 12, the uniform wiring mechanism 9 includes a pair of mounting side plates 91 fixed in the protective box 7, a rotating rod 92 is rotatably provided between the middle parts of the mounting side plates 91, one end of the rotating rod 92 passes through the mounting side plates 91 and is sleeved and fixed with a transmission wheel 93, the transmission wheel 93 is connected to the transmission wheel 1 8610 through a transmission belt 10, a groove wheel 94 is sleeved and fixed on the rotating rod 92, a double helical rotary groove 95 is reserved on the groove wheel 94, and the double helical rotary groove 95 is formed by two spiral grooves with opposite rotation directions connected to each other, a sliding rod 96 is fixedly connected between the upper parts of the mounting side plates 91, a sliding seat 97 is slidably connected to the sliding rod 96, a rotating column 98 is rotatably provided on the bottom surface of the sliding seat 97, an arc plate 99 which is slidably connected with the double helical rotary groove 95 is fixed on the rotating column 98, a sleeve barrel 910 is fixed on the sliding seat 97, and a plurality of balls 911 are arranged in the sleeve barrel 910.

The working principle of the uniform wiring mechanism 9 to evenly wind the charging cable 5 on the charging cable winding self-locking mechanism 8 is as follows: when the charging cable 5 is extended or shortened, the transmission wheel 1 8610 rotates accordingly, thereby driving the transmission wheel 2 93 to rotate synchronously under the action of the transmission belt 10. Since the transmission wheel 2 93 is sleeved and fixed on the rotating rod 2 92, the rotating rod 2 92 rotates accordingly, and the groove wheel 94 sleeved and fixed on the rotating rod 2 92 rotates accordingly. Since the double helical rotating grooves 95 on the groove wheel 94 are slidably connected with the arc plate 99 rotatably set on the slide 97, and the slide 97 is slidably set on the slide rod 96, the slide 97 will be driven to move back and forth on the slide rod 96, and the charging cable 5 will be evenly wound and rolled on the winding drum 862 through the sleeve drum 910 on the slide 97.

As shown in Figures 3, 13 and 14, the charging gun locking mechanism 11 includes a placement cylinder 111 fixed on the placement bin 3, a rotation groove 112 is reserved at the bottom of the placement cylinder 111, a rotating rod 113 is fixed to the front side of the placement bin 3, and a rotating handle 114 and a cam 115 are rotatably provided on the rotating rod 113 in sequence. The cam 115 is an arc plate structure with a diameter gradually increasing from the center to the edge, and its appearance is similar to a triangular dart. The rotating handle 114 is slidably connected to the rotating groove 112, and the rotating handle 114 is slidably connected to the rotating groove 112. 14 and the cam 115 are clamped and fixed between them, and a number of evenly distributed hinge seats 116 are fixed on the circumferential outer wall of the placement cylinder 111, and a buckle plate 117 is hinged inside the hinge seat 116. A moving rod 118 is fixed to the bottom of the buckle plate 117. The moving rod 118 passes through the placement cylinder 111 and is slidably connected to the outer wall of the cam 115. A spring is fixedly connected between the upper part of the buckle plate 117 and the placement cylinder 111, and the top of the buckle plate 117 is located on the upper side of the placement cylinder 111 and is clamped and fixed to the clamping block 12 on the charging gun 4.

The working principle of the charging gun locking mechanism 11 to lock and fix the charging gun 4 is as follows: after placing the charging head of the charging gun 4 into the placement tube 111, the handle 114 is rotated to drive the cam 115 to rotate around the rotating rod 3 113. Since the moving rod 118 at the bottom of the buckle plate 117 passes through the placement tube 111 and is slidably connected with the outer wall of the cam 115, the cam 115 drives the moving rod 118 to move to the outside of the placement tube 111 when it rotates, thereby driving the buckle plate 117 to rotate in the hinge seat 116, and the front end of the buckle plate 117 moves to the inside of the placement tube 111 until the clamping block 12 on the charging gun 4 is clamped. Since the moving rod 118 generates a centripetal force on the cam 115, the buckle plate 117 will only be driven to rotate when the handle is rotated, and the buckle plate 117 itself will not move actively, thereby producing a self-locking effect on the charging gun 4. When the charging gun 4 needs to be taken out, the handle 114 is rotated in the opposite direction, the cam 115 is separated from the moving rod 118, and the moving rod 118 moves toward the inside of the placement tube 111 under the action of the spring, thereby driving the buckle plate 117 to rotate in the hinge seat 116, and the front end of the buckle plate 117 moves toward the outside of the placement tube 111 and separates from the clamping block 12, and the charging gun 4 can be taken out of the placement tube 111 at this time.

As shown in Figures 2, 15, 16, 17 and 18, the electrical connection quick-connect wire 6 port is provided with a quick-connect plug 61, the quick-connect plug 61 port is provided with a metal terminal plate 62, the outer wall is provided with a pair of plug-in blocks 63, the outer wall of the protective box 7 is provided with a docking tube 71 connected to the fixed plate 81, and the wall of the docking tube 71 is reserved with a pair of bent docking grooves 72 that cooperate with the plug-in block 63 for sliding connection, the fixed plate 81 is provided with a connecting groove 831 that is connected to the power connection ring 83, and the metal terminal plate 62 passes through the connecting groove 831 and is electrically connected to the power connection ring 83 in contact.

The working principle of the electrical connection between the quick-connect wire 6 and the charging cable reel self-locking mechanism 8 is as follows: align the plug block 63 on the quick-connect plug 61 with the bent docking groove 72, rotate the quick-connect plug 61 so that the plug block 63 and the bent docking groove 72 slide in cooperation, until the metal terminal plate 62 on the quick-connect plug 61 passes through the connection groove 831 and then contacts the power connection ring 83 to be electrically connected.

It is particularly important to note that, during the rotation of the winding drum 862 , the connector of the brush 866 can be rotated while maintaining continuous electrical connection with the power ring 83 , thereby ensuring that the charging cable 5 is continuously electrically connected to the electrical quick-connect cable 6 .

In the specific implementation of the present invention, when the charging pile is idle and does not need to charge the vehicle, the charging gun 4 is placed in the placement compartment 3, and the rotating handle 114 is rotated to drive the front end of the buckle plate 117 to move toward the inside of the placement tube 111, and the clamping block 12 on the charging gun 4 is clamped to achieve self-locking; when the vehicle needs to be charged, the rotating handle 114 is rotated in the opposite direction to drive the buckle plate 117 to move and separate from the clamping block 12, and the charging gun 4 is taken out. When the charging cable 5 is stretched, the self-locking fixation of the charging cable 5 at a certain fixed length can be achieved through the cooperation between the turntable 863 and the locking wrench unit 810. When the charging cable 5 needs to be reeled in, the rotating handle 8101 is turned to wind the charging cable 5, thereby achieving automatic reeling of the charging cable 5.
