Description

Technical Field

[0001] The present invention relates to the technical field of charging piles, and in particular to a charging pile with a protective structure. Background Art

[0002] With the increasing popularity of electric vehicles, charging piles, as energy supply equipment for electric vehicles, are of self-evident importance. The main function of charging piles is to provide electric vehicles with electrical energy so that they can be charged during driving or when parked to meet the travel needs of users. Charging piles are connected to the charging interface of the electric vehicle to transmit electrical energy to the battery of the electric vehicle. They usually have a certain charging power and charging mode, and can be set accordingly according to the battery capacity and needs of the electric vehicle. There are various types of charging piles, including AC charging piles and DC charging piles. AC charging piles are generally suitable for slow charging scenarios in homes or public places, and the charging time is relatively long; DC charging piles can achieve fast charging, and can replenish a large amount of electrical energy for electric vehicles in a relatively short period of time. They are often used in highway service areas, urban fast charging stations and other places.

[0003] In a humid environment, condensation is very likely to form at the socket of the existing charging pile. The generation of condensation causes the electrical components to be in a damp state for a long time, which not only greatly reduces the insulation performance of the components, but also easily causes electrical short circuits and other faults, accelerates the corrosion process of the equipment, and seriously threatens the normal service life and stable operation of the charging pile. The risks caused by human static electricity are not ignored in the operation of plugging and unplugging the charging gun. When the user has static electricity on his body, direct plugging and unplugging operations are performed, and electrostatic discharge is very likely to occur. This electrostatic discharge will not only cause irreversible damage to the delicate electronic components inside the charging pile and affect the normal operation of the charging pile, but more seriously, under certain conditions, the sparks generated by electrostatic discharge may cause catastrophic consequences such as fire or explosion, posing a huge threat to the user's life and property safety.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figures 1 to 9 , the present invention provides a technical solution of a charging pile with a protective structure: A charging pile with a protective structure, comprising a charging pile 1, a wire 2 and a charging gun 3 fixedly connected to the charging pile 1 through the wire 2, the charging pile 1 is provided with a heat dissipation port 4 and a heat dissipation port 5 for heat dissipation, a static electricity removal mechanism 7 and an adjustment component 8 are provided on the charging pile 1, and the charging pile 1 is also provided with a charging gun socket 6 for preventing the charging gun 3 from being charged; The anti-static mechanism 7 includes a base 71 fixed on the charging pile 1 and a guide piece 72 fixed inside the base 71, and the guide piece 72 is connected to the ground through a wire. A conductive button 73 is movably connected to the base 71, and a convex point 74 matching the guide piece 72 is provided on the side of the conductive button 73, so that static electricity is transmitted to the ground through the wire. A threaded tube 75 is fixedly connected to the conductive button 73, and the conductive button 73 and the base 71 are fixedly connected by a spring 76, so that the conductive button 73 can be automatically reset. The inside of the threaded tube 75 A bearing seat is movably connected, and the bearing seat and the screw 77 are connected by a ball nut pair, and one end of the screw 77 is movably connected to a transmission belt 78, so that pressing the conductive button 73 drives the screw 77 to rotate, and the other end of the screw 77 is connected to a transmission rod 79 through a transmission belt 78. The transmission rod 79 is fixedly connected to a right snap ring 711, and the front end of the transmission rod 79 is movably connected to a left snap ring 710, so that when the left snap ring 710 and the right snap ring 711 are closed, the charging gun 3 is locked in the interior of the static electricity removal mechanism 7, and the left snap ring 710 and the right snap ring 711 are fixedly connected. A transmission assembly 714 is fixedly connected so that the left snap ring 710 and the right snap ring 711 rotate to both sides when the transmission rod 79 rotates. The left snap ring 710 and the right snap ring 711 are respectively detachably connected with soft plastic sheets 712, and grooves for preventing desiccant are provided between the soft plastic sheets 712 and the right snap ring 711 and the left snap ring 710 to absorb condensation at the interface between the charging gun 3 and the charging gun socket 6. Small holes 713 for ventilation and condensation entry are provided above the left snap ring 710, the right snap ring 711 and the soft plastic sheet 712. The transmission assembly 714 includes a chassis 7141, a rotating gear 7142 and a gear ring 7144, and the rotating gear 7142 and the gear ring 7144 are respectively fixedly connected to the transmission rod 79 and the left snap ring 710, and a plurality of small gears 7143 are meshedly connected between the rotating gear 7142 and the gear ring 7144 to unlock the charging gun 3 inside the charging gun socket 6 when the transmission rod 79 rotates. The other end of the right snap ring 711 is fixedly connected with a tenon 715, and a slot is provided at the opposite position of the left snap ring 710 to ensure a tight closure between the left snap ring 710 and the right snap ring 711.

[0026] During operation, before plugging in or out the charging gun 3, the user first presses the conductive button 73 by hand to move it toward the inside of the charging pile 1. During the pressing process, the conductive button 73 will move toward the inside of the charging pile 1 along the connection point between it and the base 71. At this time, the convex point 74 set on the side of the conductive button 73 will contact the guide piece 72 fixed inside the base 71. Since the guide piece 72 is connected to the ground through a wire, the static electricity carried by the human body can be conducted to the guide piece 72 through the convex point 74, and then smoothly transmitted to the ground through the wire, thereby achieving the purpose of removing static electricity from the human body. At the same time, when the conductive button 73 moves toward the inside of the charging pile 1, the threaded tube 75 fixedly connected above it will also move toward the inside of the charging pile 1 synchronously, and the threaded tube 75 moves inside The bearing seat and the screw 77 are connected by a ball nut pair, so that when the threaded tube 75 moves into the charging pile 1, the screw 77 will rotate under the action of the threaded tube 75, and the transmission belt 78 movably connected at one end of the screw 77 will transmit the rotational power of the screw 77 to the transmission rod 79 at the other end, so that the transmission rod 79 starts to rotate, and the rotation of the transmission rod 79 will drive the right snap ring 711 fixedly connected thereto to rotate together, and the rotation of the right snap ring 711 is transmitted to the left snap ring 710 through the transmission assembly 714 fixedly connected between the left snap ring 710 and the right snap ring 711, and the rotating gear 7142 (fixedly connected to the transmission rod 79), multiple pinions 7143 and gear ring 7144 (fixedly connected to the left snap ring 710) in the transmission assembly 714 The left and right snap rings 710 are fixedly connected to the charging pile 1 and mesh with each other, thereby converting the rotation of the right snap ring 711 into the reverse rotation of the left snap ring 710, so that the left snap ring 710 and the right snap ring 711 are rotated to both sides to open. At this time, the lock of the charging gun 3 is released, and the user can plug and unplug the charging gun 3. When the user completes the plugging and unplugging operation and releases the conductive button 73, the spring 76 connected between the conductive button 73 and the base 71 will play a role, and its elastic potential energy causes the conductive button 73 to rebound in the direction away from the inside of the charging pile 1 and return to its initial position. At the same time, under the action of the transmission assembly 714, the left snap ring 710 and the right snap ring 711 will rotate in the opposite direction and close again, and the tenon 715 fixedly connected at the other end of the right snap ring 711 will be embedded in the left snap ring The left snap ring 710 and the right snap ring 711 are in the card slot relative to each other, ensuring that the left snap ring 710 and the right snap ring 711 are tightly closed, so that the charging gun 3 is firmly locked in the static removal mechanism 7, effectively preventing the charging gun 3 from accidentally falling off when not in operation. In addition, the soft plastic sheets 712 that are disassembled and connected on the left snap ring 710 and the right snap ring 711, respectively, and the grooves between the soft plastic sheet 712 and the right snap ring 711 and the left snap ring 710 play an important role. The desiccant placed in the groove can absorb the condensation that may appear at the interface between the charging gun 3 and the charging gun socket 6. The small holes 713 on the soft plastic sheet 712 and the left snap ring 710 and the right snap ring 711 not only help ventilation, allowing air to circulate inside, but also ensure that the desiccant can continuously and effectively absorb condensation.It also provides a channel for condensation to enter between the soft film 712 and the clamp ring, ensuring that the desiccant can fully exert its moisture absorption function, further improving the moisture-proof protection effect of the interface of the charging gun 3.

[0027] As an embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the adjustment component 8 includes a tenon 81 movably connected to the inside of the charging gun socket 6, and the tenon 81 matches the charging gun 3, so that the tenon 81 is driven to move when the charging gun 3 is pulled out and pushed in, and two movable rods 82 are fixedly connected to the tenon 81, and two slot seats 84 are fixedly connected to the inside of the charging pile 1, and the inside of the slot seats 84 are movably connected with an inclined slot rod 86, and the side of the inclined slot rod 86 matches the movable rod 82, and the inside of the slot seat 84 is provided with an movable slot 85 matching the inclined slot rod 86, so that the inclined slot rod 86 moves toward the inside of the slot seat 84 when the movable rod 82 is pushed forward, and the inclined slot rod 86 is fixedly connected to the bottom of the slot seat 84 by a spring 2 89, so that the inclined slot rod 86 moves upward when the charging gun 3 is pulled out, and the top of the inclined slot rod 86 is fixedly connected with a top block 88, and A fan assembly 9 is fixedly connected to the top block 88 for directing the wind direction toward the inside of the left snap ring 710 and the right snap ring 711, the front end of the movable rod 82 is rotatably connected to a rotating wheel 83 for reducing friction, and a limiting groove 87 matching the rotating wheel 83 is provided on the bevel rod 86 to reduce the friction when the bevel rod 86 moves, a plurality of ball bearings for reducing friction are movably connected on the inner walls opposite to the movable groove 85 and the bevel rod 86, and a limiting block matching the movable groove 85 is fixedly connected to the bottom of the bevel rod 86 to prevent the bevel rod 86 from falling off the groove seat 84, a sliding groove 811 is provided inside the two bevel rods 86, and a straight rod 810 is fixedly connected to the inside of the charging pile 1 through the two bevel rods 86 to prevent the movable rod 82 from deviating when pushing the bevel rod 86 to move up and down.

[0028] During operation, when the user needs to pull out the charging gun 3, the action of pulling out the charging gun 3 outward with force will drive the tenon 81 to move toward the outside away from the charging pile 1, and the two movable rods 82 fixedly connected to the tenon 81 will also move toward the outside with the movement of the tenon 81, and the rotating wheel 83 rotatably connected to the front end of the movable rod 82 rolls in the limiting groove 87 provided on the inclined groove rod 86. This rolling friction method greatly reduces the friction force compared with the sliding friction, so that the movable rod 82 can push the inclined groove rod 86 to move more smoothly, and the elastic potential energy stored in the second spring 89 begins to be released, and the inclined groove rod 86 will move upward in the movable groove 85 inside the groove seat 84. In this process, the multiple balls movably connected on the relative inner walls of the movable groove 85 and the inclined groove rod 86 further reduce the friction force when the inclined groove rod 86 moves, making the movement of the inclined groove rod 86 smoother, pushing the inclined groove rod 86 to move upward, and in the process of the inclined groove rod 86 moving upward, the top block 88 fixedly connected to its top end will also move upward accordingly; When the charging gun 3 needs to be inserted, the user pushes the charging gun 3 inward, and the charging gun 3 drives the tenon 81 to move toward the inside of the charging pile 1. The movable rod 82 on the tenon 81 moves inward with the tenon 81, and the rotating wheel 83 at the front end of the movable rod 82 rolls in the limiting groove 87 of the inclined groove rod 86. Since the moving direction of the movable rod 82 changes, the movable rod 82 exerts an oblique downward force on the inclined groove rod 86. However, since the inclined groove rod 86 is affected by the upward elastic force of the second spring 89 and its own gravity when the second spring 89 is not fully compressed, the overall downward movement trend is maintained. As the charging gun 3 continues to be inserted, the movable rod 82 continues to push inward. , the force acting on the inclined slot rod 86 gradually increases, overcoming the elastic force of the second spring 89 and the gravity of the inclined slot rod 86, so that the inclined slot rod 86 moves in the movable slot 85 in an oblique upward direction (because the force acting on the inclined slot rod 86 by the movable rod 82 is oblique and has an upward component), but the overall trend is downward movement. During this process, the balls on the inner wall of the movable slot 85 and the inclined slot rod 86 and the rolling of the rotating wheel 83 in the limiting slot 87 continue to reduce the friction force, and the limiting block at the bottom of the inclined slot rod 86 prevents it from falling out. When the charging gun 3 is fully inserted, the inclined slot rod 86 returns to the initial position, waiting to repeat the above process again when the charging gun 3 is pulled out next time.

[0029] As an embodiment of the present invention, Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, the fan assembly 9 includes a limit ring 91 and a plurality of wind plates 92 rotatably connected to the limit ring 91 for changing the wind direction, and the plurality of wind plates 92 are fixedly connected by a moving block 93, a pull rod 94 is fixedly connected to the moving block 93, and the pull rod 94 is fixedly connected to the top block 88, so that the plurality of wind plates 92 are driven to rotate when the top block 88 moves up and down.

[0030] During operation, when the top block 88 moves upward, the pull rod 94 fixedly connected to the top block 88 will move upward synchronously, and the upward movement of the pull rod 94 drives the moving block 93 fixedly connected thereto to move upward. Since multiple wind plates 92 are fixedly connected together through the moving block 93, the upward movement of the moving block 93 can drive multiple wind plates 92 to rotate on the limit ring 91. The rotation of the wind plates 92 will change the wind direction, so that the wind can blow toward the inside of the left clamping ring 710 and the right clamping ring 711. Such air flow can accelerate the circulation speed of air in the area, dry the desiccant moistened by condensation, keep the interface between the charging gun 3 and the charging gun socket 6 dry, effectively prevent electrical components from getting damp, thereby ensuring the normal service life and stable operation of the charging pile 1. When the charging gun 3 is inserted, the charging gun 3 is pushed inward, and the charging The electric gun 3 will drive the tenon 81 to move inward. When the tenon 81 moves inward, the movable rod 82 on it will move backward, and the rotating wheel 83 at the front end of the movable rod 82 will roll again in the limiting groove 87 of the inclined slot rod 86, so that the inclined slot rod 86 moves downward under the action of the movable rod 82. When the inclined slot rod 86 moves downward, the top block 88 at its top will also move downward. The top block 88 drives the moving block 93 to move downward through the pull rod 94, thereby causing the wind plate 92 to rotate in the opposite direction and stop blowing. During the working process of the entire adjustment component and the fan component, the sliding groove 811 opened inside the two inclined slot rods 86 and the straight rod 810 inside the charging pile 1 that runs through the two inclined slot rods 86 and is fixedly connected to each other cooperate with each other to ensure that the movable rod 82 will not deviate when pushing the inclined slot rod 86 to move up and down, thereby ensuring the stability and accuracy of the operation of the entire mechanism.

[0031] Working principle: During operation, before plugging in or out the charging gun 3, the user needs to first press the conductive button 73 to make it move toward the inside of the charging pile 1. During this process, the convex point 74 on the side of the conductive button 73 contacts the guide plate 72 in the base 71, and the static electricity of the human body is transmitted to the ground through the guide plate 72 and the wire, thereby achieving the purpose of removing static electricity. At the same time, the conductive button 73 drives the threaded tube 75 to move toward the inside of the charging pile 1 synchronously. Since the threaded tube 75 is connected to the screw rod 77 through a ball nut pair, the screw rod 77 rotates, and its rotational power is transmitted to the transmission rod 79 through the transmission belt 78. The transmission rod 79 drives the right snap ring 711 to rotate, and then the rotation is transmitted to the left snap ring 710 through the transmission assembly 714 composed of a rotating gear 7142, a pinion 7143 and a gear ring 7144, so that the left snap ring 710 The right snap ring 711 is rotated to both sides to open, and the charging gun 3 is unlocked, so that the user can plug and unplug the charging gun 3. When the user completes the plugging and unplugging operation and releases the conductive button 73, the spring 1 76 causes the conductive button 73 to rebound and reset. At the same time, under the action of the transmission component 714, the left snap ring 710 and the right snap ring 711 rotate in opposite directions to close, and the tenon 715 of the right snap ring 711 is embedded in the slot of the left snap ring 710, locking the charging gun 3 in the static electricity removal mechanism 7. The soft plastic sheet 712 and the desiccant in the groove absorb condensation at the interface between the charging gun 3 and the charging gun socket 6. The small hole 713 ensures ventilation and condensation entry. When the user needs to unplug the charging gun 3, the outward pulling action drives the tenon 81 to move away from the outside of the charging pile 1, and the movable rod 82 on the tenon 81 Then it moves outward, and the front end wheel 83 of the movable rod 82 rolls in the limiting groove 87 of the inclined groove rod 86, reducing the friction force, so that the inclined groove rod 86 moves upward in the movable groove 85 of the groove seat 84. In this process, the movable groove 85 and the inclined groove rod 86 further reduce the friction force relative to the inner wall ball, and the limiting block at the bottom of the inclined groove rod 86 prevents it from falling out. At the same time, the spring 2 89 releases elastic potential energy to assist the inclined groove rod 86 to move upward, and the top block 88 at the top of the inclined groove rod 86 moves upward accordingly. When the top block 88 moves upward, the movable block 93 is driven upward by the pull rod 94, thereby causing the wind plate 92 to rotate on the limiting ring 91, changing the wind direction to blow to the inside of the left clamping ring 710 and the right clamping ring 711, accelerating the air circulation to dry the desiccant moistened by condensation, and maintaining the interface between the charging gun 3 and the charging gun socket 6. When the charging gun 3 needs to be inserted, the charging gun 3 is pushed inward, which drives the tenon 81 to move toward the inside of the charging pile 1, and the movable rod 82 on the tenon 81 moves inward, and the rotating wheel 83 rolls in the limiting groove 87. The movable rod 82 exerts an oblique downward force on the inclined slot rod 86. At first, the inclined slot rod 86 is affected by the upward elastic force of the spring 89 and its own gravity, and the overall downward movement trend is maintained. As the charging gun 3 continues to be inserted, the force of the movable rod 82 on the inclined slot rod 86 increases, overcoming the elastic force of the spring 89 and gravity, so that the inclined slot rod 86 moves in the movable slot 85 in an oblique upward direction but moves downward as a whole. In this process, the movable slot 85 and the inclined slot rod 86 roll relative to the inner wall ball and the rotating wheel 83 to continuously reduce the friction, and the limiting block at the bottom of the inclined slot rod 86 prevents it from falling out.When the charging gun 3 is fully inserted, the inclined slot rod 86 returns to the initial position and waits for the next time the charging gun 3 is pulled out to repeat the above process. During the operation of the entire adjustment component and the fan component, the internal slide groove 811 of the inclined slot rod 86 and the internal straight rod 810 of the charging pile 1 work together to ensure that the movable rod 82 does not deviate when pushing the inclined slot rod 86 up and down, thereby ensuring the stability and accuracy of the mechanism operation.
