[0001] The present application relates to the technical field of charging pile equipment, and in particular to a charging pile that prevents gun heads from falling off. Background Art

[0002] Charging piles are usually installed in parking lots or charging stations in public buildings, shopping malls, public parking lots, residential communities and other places. They can charge electric vehicles of various models according to different voltage levels.

[0003] When using a charging pile, remove the charging gun head from the placement slot on the charging pile and install it at the charging port of the electric car. When the electric car is fully charged, remove the gun head and install it in the placement slot of the charging pile to complete the charging of the electric car.

[0004] In the related art, the gun head is inserted into the placement groove, which may easily cause the gun head to be separated from the placement groove and fall off in the case of human scratches or natural wind, thus affecting the service life of the gun head. Utility Model Content

[0005] In order to reduce the adverse effects on the service life of the gun tip, the present application provides a charging pile that prevents the gun tip from falling.

[0006] The present application provides a charging pile that prevents the gun head from falling, which adopts the following technical solution:

[0007] A charging pile for preventing a gun head from falling comprises a pile body and a gun head, wherein the pile body is provided with a fixing plate perpendicular to the height direction of the pile body, a plug-in hole is provided on a side of the fixing plate close to the gun head, when the gun head is plugged into the plug-in hole, the upper end of the gun head overlaps the fixing plate, and a limiting member for limiting the position of the gun head is provided on the fixing plate.

[0008] By adopting the above technical solution, the gun head is inserted into the plug-in hole. At this time, the upper end of the gun head overlaps with the upper side of the fixing plate, and the gun head is limited by the limiting piece. At this time, the gun head is located between the fixing plate and the limiting piece, thereby reducing the possibility of the gun head falling and reducing the adverse effects on the service life of the gun head.

[0009] Optionally, the limiting member includes a hydraulic cylinder installed on one side of the fixed plate and parallel to the width direction of the plug-in hole, the telescopic rod of the hydraulic cylinder is inserted into the plug-in hole and is slidably connected to the fixed plate, and when the gun head is plugged into the plug-in hole, the telescopic rod of the hydraulic cylinder is located on the side of the gun head close to the slot of the plug-in hole.

[0010] By adopting the above technical solution, the gun head is plugged into the socket, and the telescopic rod of the hydraulic cylinder is extended to limit the gun head, reducing the possibility of the gun head falling. When the gun head needs to be taken, the telescopic rod of the hydraulic cylinder is shortened, and the gun head can slide along the length direction of the socket, thereby facilitating the removal of the gun head and improving the charging efficiency.

[0011] Optionally, the pile body is provided with an installation groove, in which a sliding frame is slidably connected, which is arranged along the height direction of the pile body and has an opening facing a side away from the pile body, the fixing plate is fixedly connected to the sliding frame, a spring is fixedly connected to the side of the sliding frame inserted into the installation groove, one end of the spring away from the sliding frame is fixedly connected to the pile body, an installation door for blocking the sliding frame is connected to the pile body, a fixing piece for fixing the installation door is provided on the pile body, and when the installation door is closed, the spring is in a compressed state.

[0012] By adopting the above technical solution, when the installation door is closed, the spring is in a compressed state, and the sliding frame, the fixed plate and the gun head are all located in the installation groove, thereby reducing the possibility of the gun head falling off due to human collision and natural wind, and at the same time making the gun head less likely to age in natural environments such as rain and snow, further reducing the adverse effects on the service life of the gun head, and when it needs to be taken, the installation door is opened through the fixing part. At this time, the spring restores its deformation and pushes the sliding frame to drive the gun head to move to the outside of the pile body, further facilitating the removal of the gun head and improving the charging efficiency.

[0013] Optionally, the fixing member includes a screw rod slidably connected to one side of the installation door, one end of the screw rod away from the pile body is fixedly connected to a limiting block, and the other end of the screw rod is threadedly connected to the pile body.

[0014] By adopting the above technical solution, the installation door is driven to rotate along the hinged side. At this time, the installation door squeezes the side of the sliding frame close to the sliding frame and pushes the sliding frame to move in the direction close to the installation groove until the sliding frame completely enters the installation groove. At this time, the installation door completely blocks the installation groove, and the screw is turned and driven to move in the direction close to the pile body until the limit block abuts against the side wall of the installation door. At this time, the screw fixes the installation door and the pile body, reducing the possibility of rain and snow entering the installation groove, and further reducing the adverse effects on the service life of the gun head.

[0015] Optionally, a ball bearing is rotatably connected to the lower side of the sliding frame.

[0016] By adopting the above technical solution, in the process of driving the sliding frame to move, the ball rotates with the movement of the sliding frame, thereby reducing the friction force on the sliding frame, further facilitating the taking and fixing of the gun head.

[0017] Optionally, a first electric wire is installed at the lower end of the gun head, a second electric wire is installed at the lower side of the interior of the sliding frame, and a storage component for connecting the first electric wire and the second electric wire and storing the first electric wire is provided in the sliding frame.

[0018] By adopting the above technical solution, when using the gun head, the storage component allows the first wire to adapt to the charging needs of the electric vehicle, and at the same time connects the first wire and the second wire and energizes them. After charging is completed and the gun head is fixed on the fixing plate, the storage component stores the excess first wire, thereby reducing the possibility of the excess first wire being squeezed and damaged by the installation door, and further extending the service life of the gun head.

[0019] Optionally, the storage assembly includes a slip ring connecting the first wire and the second wire, the second wire is installed on the stator of the slip ring, the sliding frame is rotatably connected to a winding roller fixedly connected to the rotor of the slip ring, a motor is installed at one end of the winding roller, and one end of the second wire away from the gun head is wound around the winding roller and passed through the winding roller to be installed on the rotor of the slip ring.

[0020] By adopting the above technical solution, when the gun head is used, the motor drives the winding roller to drive the rotor and the end of the first electric wire fixed on the rotor to rotate. At this time, the length of the first electric wire wound on the winding roller gradually decreases, so as to facilitate meeting the demand for the first electric wire when the electric vehicle is charged. When the charging is completed and the gun head is fixed on the fixed plate, the motor drives the winding roller to drive the rotor to flip, so that the excess first electric wire is wound on the winding roller, which is convenient for storing the first electric wire and further extending the service life of the gun head.

[0021] Optionally, the upper end of the mounting door is arranged as an inclined surface which is inclined downward and away from the pile body.

[0022] By adopting the above technical solution, in rainy and snowy weather, rain and snow fall on the upper end of the installation door and fall along the inclined surface of the upper end of the installation door, thereby reducing the possibility of rain and snow entering the installation groove and further reducing the adverse effect on the service life of the gun head.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Insert the gun head into the plug hole. At this time, the upper end of the gun head overlaps with the upper side of the fixing plate. The gun head is limited by the limiting piece. At this time, the gun head is located between the fixing plate and the limiting piece, thereby reducing the possibility of the gun head falling and reducing the adverse effects on the service life of the gun head;

[0025] 2. When the installation door is closed, the spring is in a compressed state, and the sliding frame, the fixing plate and the gun head are all located in the installation groove, thereby reducing the possibility of the gun head falling due to human collision and natural wind, and making the gun head less likely to age in natural environments such as rain and snow, further reducing the adverse effects on the service life of the gun head, and when it needs to be taken, the installation door is opened through the fixing part, at this time the spring restores its deformation and pushes the sliding frame to drive the gun head to move to the outside of the pile body, further facilitating the removal of the gun head and improving the charging efficiency;

[0026] 3. When using the gun head, the motor drives the winding roller to drive the rotor and one end of the first wire fixed on the rotor to rotate. At this time, the length of the first wire wound on the winding roller gradually decreases, so as to facilitate meeting the demand for the first wire when the electric vehicle is charged. When the charging is completed and the gun head is fixed on the fixed plate, the motor drives the winding roller to drive the rotor to flip, so that the excess first wire is wound on the winding roller, which is convenient for storing the first wire and further extending the service life of the gun head.

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] The present application embodiment discloses a charging pile that prevents the gun head from falling. Figure 1 and Figure 2A charging pile for preventing a gun head 3 from falling comprises a pile body 1 and a mounting groove 11 which is opened on one side of the pile body 1 and arranged along the height direction of the pile body, wherein the notch of the mounting groove 11 faces the side away from the inside of the pile body 1, and a sliding frame 2 which is arranged along the height direction of the pile body 1 and has an opening facing the same direction as the notch of the mounting groove 11 is provided in the mounting groove 11, and both ends of the sliding frame 2 in the height direction are slidably connected to the side wall of the pile body 1.

[0033] A sliding block 21 is fixedly connected to the middle of the lower end of the sliding frame 2. A sliding groove 12 is provided on the pile body 1, which is connected to the installation groove 11 and opens upward. The sliding block 21 is inserted into the sliding groove 12 and moves along the length direction of the sliding groove 12. A ball bearing (not shown in the figure) is rotatably connected to the lower end of the sliding block 21. Three springs 22 are evenly distributed horizontally along the height direction of the sliding tube and fixedly connected to one side of the vertical side of the sliding frame 2 and close to the bottom of the installation groove 11. The ends of the springs 22 away from the sliding frame 2 are fixedly connected to the side wall of the pile body 1.

[0034] Reference Figure 2 A horizontal fixing plate 13 is fixedly connected to the upper end of the interior of the sliding frame 2. A plug hole 131 with an opening facing the same direction as the slot of the mounting slot 11 is provided on the side of the fixing plate 13 close to the opening of the sliding frame 2. A gun head 3 for charging an electric vehicle is provided in the sliding frame 2. The lower end of the gun head 3 is plugged into the plug hole 131. At this time, the upper end of the gun head 3 is overlapped on the fixing plate 13, and a limiting member is provided on the fixing plate 13, which is located on the side of the gun head 3 away from the spring 22 and limits the lower end of the gun head 3.

[0035] A first wire 31 is installed at the lower end of the gun head 3 , a second wire 32 is installed at the lower side of the sliding frame 2 , and a storage component 4 is provided between the first wire 31 and the second wire 32 to connect the two and store the first wire 31 .

[0036] Reference Figure 1 and Figure 2 On the outer side wall of the pile body 1 close to the installation groove 11, a mounting door 14 is provided which blocks the installation groove 11 and is hinged to the pile body 1 on one vertical side. A fixing piece 15 fixed to the pile body 1 is provided on the side of the installation door 14 away from the hinged side, and the upper side of the installation door 14 is provided with an inclined surface which is inclined downward and away from the pile body 1. When the installation door 14 blocks the installation groove 11, the sliding frame 2 is completely located in the installation groove 11, and the spring 22 is compressed. A sealing gasket 141 arranged along the edge of the installation door 14 is fixedly connected to the side of the installation door 14 close to the pile body 1. A sealing groove 16 adapted to the sealing gasket 141 is provided on the pile body 1. When the installation door 14 is closed, the sealing gasket 141 is inserted into the sealing groove 16 to improve the sealing performance of the installation door 14.

[0037] When placing the gun head 3, the gun head 3 is inserted into the insertion hole 131. At this time, the upper end of the gun head 3 overlaps with the upper side of the fixing plate 13, and the gun head 3 is limited by the limiter. The storage component 4 stores the redundant first wire 31 until the first wire 31 and the second wire 32 are both located in the sliding frame 2. At this time, the installation door 14 is closed, and the side wall of the installation door 14 pushes the sliding frame 2 to move into the installation groove 11. At this time, the sliding block 21 slides in the sliding groove 12 until the installation door 14 blocks the installation groove 11. At this time, the spring 22 is in a compressed state, and the installation door 14 is fixed to the pile body 1 by the fixing member 15, so that the gun head 3 is fixed, and at the same time, the gun head 3 is not easy to age in natural environments such as rain and snow.

[0038] When the gun head 3 is used, the installation door 14 is opened through the fixing piece 15. At this time, the spring 22 recovers its deformation and pushes the sliding frame 2 to drive the gun head 3 to move to the outside of the pile body 1. The limit of the gun head 3 is released by the limit piece, and the storage component 4 drives the length of the first wire 31 to adapt to the charging demand. At the same time, the first wire 31 and the second wire 32 are connected and energized until charging is completed.

[0039] In the process of driving the sliding frame 2 to move, the ball rotates with the movement of the sliding frame 2, reducing the friction force on the sliding frame 2, making it easier to take and fix the gun head 3, and in rainy and snowy weather, rain and snow fall on the upper end of the installation door 14 and fall along the inclined surface of the upper end of the installation door 14, reducing the possibility of rain and snow entering the installation groove 11.

[0040] Reference Figure 2 In the embodiment of the present application, the limiting member is configured as a hydraulic cylinder 132, which is parallel to the width direction of the installation door 14 and fixedly connected to the side wall of the fixed plate 13, and the telescopic rod of the hydraulic cylinder 132 passes through one side of the fixed plate 13 and is inserted into the plug hole 131. When the telescopic rod of the hydraulic cylinder 132 abuts against the side wall of the plug hole 131 away from the hydraulic cylinder 132, the hydraulic cylinder 132 and the plug hole 131 close to the spring 22 limit the gun head 3.

[0041] The gun head 3 is inserted into the insertion hole 131. At this time, the telescopic rod of the hydraulic cylinder 132 is extended and limits the gun head 3, reducing the possibility of the gun head 3 falling. When the gun head 3 needs to be taken, the telescopic rod of the hydraulic cylinder 132 is shortened. At this time, the gun head 3 can slide along the length direction of the insertion hole 131, which is convenient for taking the gun head 3.

[0042] Reference Figure 2 and Figure 3 The fixing member 15 includes a screw rod 151 that passes through a side of the installation door 14 away from the hinged side and is slidably connected to the installation door 14. The screw rod 151 is horizontal and faces the pile body 1. One end of the screw rod 151 away from the pile body 1 is fixedly connected to the limiting block 152, and the end of the screw rod 151 close to the pile body 1 is threadedly connected to the pile body 1.

[0043] The installation door 14 is driven to rotate along the hinged side. At this time, the installation door 14 squeezes and pushes the sliding frame 2 to move toward the installation groove 11 on the side close to the sliding frame 2 until the sliding frame 2 completely enters the installation groove 11. The screw 151 is turned and driven to move toward the pile body 1 until the limit block 152 abuts against the side wall of the installation door 14. At this time, the screw 151 fixes the installation door 14 and the pile body 1 to reduce the possibility of rain and snow entering the installation groove 11.

[0044] Reference Figure 2 The storage assembly 4 includes a horizontal slip ring 41 arranged at one end of the second electric wire 32 away from the side wall of the sliding frame 2, the stator of the slip ring 41 is fixedly connected to the end of the second electric wire 32, and the rotor of the slip ring 41 is fixedly connected to a winding roller 42 that is rotatably connected to the sliding frame 2. The first electric wire 31 is wound on the outer wall of the winding roller 42, and the end of the first electric wire 31 away from the gun head 3 is inserted into the winding roller 42 and fixedly connected to the winding roller 42. The first electric wire 31 and the second electric wire 32 can be connected and conductive through the slip ring 41 and the winding roller 42, and the end of the winding roller 42 away from the slip ring 41 is installed with a motor 43 fixedly connected to the sliding frame 2.

[0045] When the gun head 3 is in use, the motor 43 drives the winding roller 42 to drive the rotor and one end of the first wire 31 fixed on the winding roller 42 to rotate. At this time, the length of the first wire 31 wound on the winding roller 42 gradually decreases, so as to facilitate meeting the demand for the first wire 31 when the electric vehicle is charged. When the charging is completed and the gun head 3 is fixed on the fixed plate 13, the motor 43 drives the winding roller 42 to drive the rotor to flip, so that the excess first wire 31 is wound on the winding roller 42, so as to facilitate the storage of the first wire 31.

[0046] The implementation principle of the charging pile for preventing the gun head 3 from falling off in the embodiment of the present application is as follows: the gun head 3 is plugged into the plug hole 131, at which time the upper end of the gun head 3 overlaps the upper side of the fixing plate 13, the gun head 3 is limited by the hydraulic cylinder 132, and the motor 43 drives the winding roller 42 to store the redundant first wire 31 until the first wire 31 and the second wire 32 are both located in the sliding frame 2, at which time the installation door 14 is closed, and the side wall of the installation door 14 pushes the sliding frame 2 to move into the installation groove 11 until the installation door 14 blocks the installation groove 11, and the sliding frame 2 is completely located in the installation groove 11, and the installation door 14 is fixed to the pile body 1 by the screw 151, so that the gun head 3 is fixed, and at the same time, the gun head 3 is not easy to age in natural environments such as rain and snow.
