Description

Technical Field

[0001] This invention relates to the technical field of charging pile plugs, and more specifically, to a charging pile plug structure that is protected against electric shock. Background Technology

[0002] Charging piles are charging devices that provide energy replenishment for electric vehicles. Their function is similar to that of a gas pump in a gas station. They can be fixed to the ground or a wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. They can charge various models of electric vehicles according to different voltage levels.

[0003] Currently, the plug structure of charging piles mainly consists of wires and a charging head. However, this common structure still has certain shortcomings in daily use. Because the opening position of the cover of the charging port varies among different new energy vehicles, some types can be flipped up to the top of the charging port during charging. This effectively reduces the possibility of rainwater soaking the charging head and charging port. However, some types of new energy vehicles have the cover folded to the side of the charging port, which cannot effectively protect against rainwater, allowing rainwater to easily soak the charging head and increasing the risk of electric shock to users. Based on the above problems, we provide a charging pile plug structure that prevents electric shock.

[0004] The information disclosed above in this background section is only for enhancing the understanding of the background section of this invention, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0005] To address the problems mentioned in the background art, the present invention provides a charging pile plug structure that prevents electric shock.

[0006] The electric shock resistant charging pile plug structure provided by this invention adopts the following technical solution: A charging pile plug structure that is protected against electric shock includes: a plug body and a handle. A mounting bracket is installed on the upper surface of the plug body. A sliding sleeve is sleeved on the upper part of the mounting bracket. A plug rod is assembled on the lower surface of the sliding sleeve, and one end of the plug rod passes through one side of the mounting bracket. A limiting component for limiting the plug rod is provided on one side of the mounting bracket. The upper surface of the sliding sleeve is equipped with a support rod, and an I-shaped plate is fixedly connected to one end of the support rod. Both sides of the I-shaped plate are rotatably connected to baffles. A rubber curtain is installed on one side of the baffle adjacent to the right angle. A control component for controlling the simultaneous rotation of the two baffles is installed on the upper surface of the I-shaped plate.

[0007] Preferably, the limiting component includes a limiting rod, a resistance spring, and an arc-shaped tip. The two outer ends of the resistance spring are fixed to the inner wall of the mounting frame and the upper surface of the arc-shaped tip, respectively. One outer end of the limiting rod passes through the top wall of the mounting frame and the inside of the resistance spring and is fixed to the upper surface of the arc-shaped tip. The insert has several limiting holes inside that are adapted to the size of the outer arc-shaped tip.

[0008] Preferably, the control component includes a fixed frame and a reciprocating lead screw. The fixed frame is mounted on the upper surface of the I-shaped plate. One end of the reciprocating lead screw passes through the top wall of the fixed frame and rotates with the upper surface of the I-shaped plate. A sleeve block is screw-driven on the outside of the reciprocating lead screw. Side rods are fixedly connected to both sides of the sleeve block. A toothed plate is fixedly connected to one end of the side rod. A rotating shaft is rotatably connected inside the I-shaped plate, and the outside of the rotating shaft is fixed to the inside of the baffle. A driven gear is installed on one end of the rotating shaft, and the driven gear meshes with the toothed plate.

[0009] Preferably, a slider is fixedly connected to one side of the outer side of the sleeve block, and the outer side of the slider slides in relation to the inside of the fixing frame. The side wall of the fixing frame is provided with a rectangular groove that matches the size of the outer side of the slider.

[0010] Preferably, an annular plate is fixedly connected to the lower surface of the sleeve block, and several bristles are evenly distributed in the inner circle of the annular plate.

[0011] Preferably, the toothed plate and the driven gear have the same width.

[0012] Preferably, a rubber strip is adhered to one side of the concave surface of the I-shaped plate, and the outer side of the rubber strip is attached to the corresponding edge of the baffle.

[0013] Preferably, a rubber pad is adhered to the outer side of the I-shaped plate away from the support rod.

[0014] In summary, the present invention has the following beneficial technical effects: 1. The arc-shaped tip can automatically embed into the corresponding limiting hole to achieve automatic limiting of the plug rod, ensuring the stability of the I-shaped plate when it is placed above the charging port. At the same time, by rotating the reciprocating screw, the sleeve can drive the side rod and toothed plate to move up, so that the driven gear rotates counterclockwise, driving the rotating shaft rod and the baffle to rotate. Thus, the two side baffles can rotate to a horizontal state. In this way, the two side baffles, the rubber curtain and the I-shaped plate can effectively block rainwater from the plug body interface, preventing rainwater from wetting the plug body interface and causing electric shock to the user, thus improving the safety of the plug body during use.

[0015] 2. When the toothed plate moves up and down, it can drive the driven gear to rotate clockwise or counterclockwise, which facilitates the folding and unfolding of the side panels and avoids the side panels being obstructed by the vehicle's side cover when moving, so that the plug body can be smoothly inserted into the charging port.

[0016] 3. The ring plate and several bristles can move up and down synchronously with the sleeve block, so that the bristles can clean the dust attached to the outside of the reciprocating screw in a timely manner, maintaining the smooth rotation of the reciprocating screw during long-term use.

[0017] The above overview is for illustrative purposes only and is not intended to be limiting in any way.

[0020] The following is in conjunction with the appendix Figures 1 to 6 The present invention will be described in further detail below.

[0021] It should be noted that the accompanying drawings are schematic and not to scale. For clarity and convenience, the relative dimensions and proportions of the parts shown are exaggerated or reduced in size; all dimensions are merely illustrative and not limiting. Furthermore, the same reference numerals are used for the same structures, elements, or fittings appearing in more than two drawings to indicate similar features.

[0022] This invention discloses a charging pile plug structure that prevents electric shock. (Refer to...) Figures 1 to 6 The device includes a plug body 1 and a handle 2. The handle 2 allows the user to control the plug body 1. A mounting bracket 10 is mounted on the upper surface of the plug body 1. A sliding sleeve 13 is fitted onto the upper part of the mounting bracket 10. A plug rod 14 is mounted on the lower surface of the sliding sleeve 13. One end of the plug rod 14 passes through the outer side of the mounting bracket 10, so that when the support rod 12 moves, it can move the plug rod 14 synchronously through the sliding sleeve 13. At the same time, a limiting component is provided on one side of the inside of the mounting bracket 10 to limit the plug rod 14. The limiting component can cooperate with the plug rod 14 to quickly limit the support rod 12. The upper surface of the sliding sleeve 13 is equipped with a support rod 12. One end of the support rod 12 is fixedly connected to an I-shaped plate 8. Both sides of the I-shaped plate 8 are rotatably connected to baffles 9. A rubber curtain 7 is installed on one side of the baffle 9 adjacent to the right angle. The upper surface of the I-shaped plate 8 is equipped with a control component for controlling the simultaneous rotation of the two baffles 9. The control component can drive the two baffles 9 to rotate, so that the two baffles 9 can rotate to a horizontal state. Thus, the two baffles 9 and the I-shaped plate 8 can effectively block rainwater from the interface of the plug body 1, preventing rainwater from wetting the interface of the plug body 1 and causing electric shock to the user, thereby improving the safety of the plug body 1 during use. At the same time, the rubber curtains 7 on both sides of the lower edge of the baffle 9 facilitate the blocking of side rainwater, further improving the rain-proofing effect of the baffle 9.

[0023] Reference Figures 1 to 2 as well as Figure 4 The limiting component includes a limiting rod 19, a resistance spring 22, and an arc-shaped tip 20. The two outer ends of the resistance spring 22 are fixed to the inner wall of the mounting frame 10 and the upper surface of the arc-shaped tip 20, respectively. One outer end of the limiting rod 19 passes through the top wall of the mounting frame 10 and the interior of the resistance spring 22 and is fixed to the upper surface of the arc-shaped tip 20. The insertion rod 14 has several limiting holes 21 that are adapted to the size of the arc-shaped tip 20. When the insertion rod 14 is subjected to an external force greater than the reverse force of the resistance spring 22, the arc-shaped tip 20 embedded in the limiting hole 21 can be moved out, which facilitates the movement of the insertion rod 14. At the same time, the resistance spring 22 can also drive the arc-shaped tip 20 to automatically re-embed into the next corresponding limiting hole 21, thereby achieving automatic limiting of the insertion rod 14.

[0024] Reference Figures 1 to 3 as well as Figure 5 The control assembly includes a fixed frame 4 and a reciprocating screw 3. The fixed frame 4 is mounted on the upper surface of the I-shaped plate 8. One end of the reciprocating screw 3 passes through the top wall of the fixed frame 4 and rotates with the upper surface of the I-shaped plate 8. A sleeve block 17 is screw-driven on the outside of the reciprocating screw 3. Side rods 5 are fixedly connected to both sides of the sleeve block 17. A toothed plate 11 is fixedly connected to one end of the side rods 5. By rotating the reciprocating screw 3, the sleeve block 17 can be moved up and down, so that the side rods 5 and the toothed plate 11 can move synchronously. The 8 is internally rotatably connected to a rotating shaft 23, and the outside of the rotating shaft 23 is fixed to the inside of the baffle 9. A driven gear 16 is installed at one end of the outside of the rotating shaft 23, and the driven gear 16 meshes with the toothed plate 11, so that when the toothed plate 11 moves up and down, it can drive the driven gear 16 to rotate clockwise or counterclockwise, which facilitates the folding and unfolding of the two side baffles 9, avoids the obstruction of the side cover of the vehicle when the two side baffles 9 move, and makes it easy for the plug body 1 to be smoothly inserted into the charging port.

[0025] Reference Figure 1 and Figure 6 The outer side of the sleeve block 17 is fixedly connected to a slider 15, and the outer side of the slider 15 slides with the inside of the fixing frame 4. The side wall of the fixing frame 4 is provided with a rectangular groove that matches the size of the slider 15. When the sleeve block 17 moves, the slider 15 can move synchronously in the rectangular groove of the fixing frame 4, ensuring the stability of the sleeve block 17 when it moves up and down.

[0026] Reference Figure 6 The lower surface of the sleeve block 17 is fixedly connected to an annular plate 24. Several bristles 25 are evenly distributed in the inner circle of the annular plate 24. The annular plate 24 and the several bristles 25 can move up and down synchronously with the sleeve block 17, so that the several bristles 25 can clean the dust attached to the outside of the reciprocating screw 3 in a timely manner, and maintain the smooth rotation of the reciprocating screw 3 during long-term use.

[0027] Reference Figures 1 to 3 as well as Figure 5 The toothed plate 11 and the driven gear 16 have the same width, so that the side edge of the toothed plate 11 does not touch the outside of the I-shaped plate 8, reducing the resistance of the toothed plate 11 during movement and making it easier for the user to rotate the reciprocating screw 3 by external force.

[0028] Reference Figures 1 to 3 as well as Figure 5A rubber strip 18 is bonded to one side of the concave surface of the I-shaped plate 8, and the outer side of the rubber strip 18 is attached to the corresponding side edge of the baffle 9. The rubber strip 18 can effectively block the gap between the baffle 9 and the I-shaped plate 8, preventing some rainwater from splashing into the interface of the plug body 1 from the gap, while not affecting the normal rotation of the baffle 9.

[0029] Reference Figure 1 A rubber pad 6 is attached to the outer side of the I-shaped plate 8 away from the support rod 12 to prevent the outer side of the I-shaped plate 8 from causing excessive pressure on the vehicle's contact area and damaging the vehicle's paint.

[0030] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0031] The implementation principle of the anti-electric shock charging pile plug structure of this invention is as follows: When in use, the user holds the plug body 1 with the handle 2 and places the rubber pad 6 against the charging port of the vehicle. Then, the plug body 1 interface is pushed into the charging port. During this process, the I-shaped plate 8 is squeezed and moves. Then, when the I-shaped plate 8 moves, it drives the support rod 12, the sliding sleeve 13 and the plug rod 14 to move, so that the arc-shaped tip 20 can automatically embed into the corresponding limiting hole 21, thereby quickly limiting the plug rod 14 and ensuring the stability of the I-shaped plate 8 when it is placed above the charging port, thus improving the convenience of using the device. Next, by rotating the reciprocating screw 3, the sleeve block 17 is moved upward. When the sleeve block 17 moves upward, it can simultaneously drive the side rods 5 and the toothed plate 11 on both sides to move upward. Since the toothed plate 11 meshes with the driven gear 16, when the toothed plate 11 moves upward, it can drive the driven gear 16 to rotate counterclockwise. Then, the rotating driven gear 16 can drive the rotating shaft rod 23 and the baffle 9 to rotate, so that the baffles on both sides can rotate to a horizontal state. Thus, the baffles on both sides and the I-shaped plate 8 can effectively block rainwater from the interface of the plug body 1, preventing rainwater from wetting the interface of the plug body 1 and causing electric shock to the user, thereby improving the safety of the plug body 1 during use. At the same time, the rubber curtains 7 on both sides of the lower edge of the baffle 9 can facilitate the blocking of side rainwater, further improving the rain-proofing effect of the baffle 9.
