[0016] The application provides a direct-current double-gun charging pile, and belongs to the technical field of energy supply device manufacturing.

[0017] 1. This invention, by setting up a protective mechanism, causes the torsion spring between the rotating shaft and the sliding plate to deform when the shaft rotates, thereby applying rotational resistance to the hinge plate and the sponge sleeve and providing buffer braking when the vehicle is slowly reversing. As a result, the driver inside the vehicle can feel the resistance behind in time, thus realizing the need to brake in time and avoiding the safety problem of impact damage to the DC dual-gun charging pile and causing fire. At the same time, the sponge sleeve, made of sponge material, wraps around the outside of the connecting plate and can prevent vehicle collision damage, protect the vehicle from damage, and also ensure the safety of the DC dual-gun charging pile.

[0018] 2. By setting up a protective mechanism, when the sponge sleeve is pushed, it will simultaneously push the telescopic rod that is hinged to the hinge plate, causing the telescopic rod to retract. After the telescopic rod retracts, it will squeeze the internal air out through the one-way ventilation alarm whistle. The one-way ventilation alarm whistle will generate sound to remind the driver in the vehicle and the surrounding pedestrians or staff, so that they can discover it in time or have others stop it in time, preventing the situation from being accidentally reversed and colliding with the DC dual gun charging pile and causing a disaster.

[0019] 3. This invention, by setting up a protective mechanism, uses a sliding plate to move the DC dual-gun charging pile backward a certain distance to avoid impact from the vehicle and buffer the impact force. At the same time, the sponge sleeve contacts the vehicle to prevent the DC dual-gun charging pile from being directly hit by the vehicle. This protects the DC dual-gun charging pile from impact and also reduces the vibration caused by the impact. The DC dual-gun charging pile also avoids direct contact impact in time by moving backward.

[0020] 4. This invention, through the setting of a protective mechanism, enables the vehicle to be restricted and warned when it slowly approaches, by using the torsion spring between the pivot and the sliding plate through the sponge sleeve. When the vehicle hits the sponge sleeve at excessive speed, the internal spring with greater elasticity inside the thick telescopic rod directly buffers the impact. After the thick telescopic rod is pushed back to its maximum extent, the sponge sleeve will continue to be squeezed by the vehicle and rotate upward. The air pressure inside the telescopic rod will then block the impact of any remaining impact from the vehicle. Furthermore, by taking targeted buffering measures according to different vehicle impact patterns, the invention achieves the maximum buffering effect.

[0021] 5、The warning mechanism is set, the swing of the swing rod and the swing board in the groove in the swing rod are utilized to realize the swing and the reflection to the outside, the setting of the reflection groove can make the swing board reflect the light, and the action of back and forth swing is utilized to complete the dynamic reflection to remind the surrounding vehicles and personnel that the impact occurs here, due to the setting of the buffering effect, the vehicle impact energy can be absorbed, and the impact sound is also reduced, the swing of the swing rod and the dynamic reflection of the reflection groove are utilized to realize the reminding of the surrounding vehicles and pedestrians, so that the irrelevant personnel quickly move away, the staff quickly observe and come to rescue and repair in time.

[0022] 6、The warning mechanism is set, so that the swing board produces the air pressure difference left and right in the swing of the swing rod, the swing board is rapidly rotated back and forth on the rotating rod through the elastic force of the short spring, the vibration can make the reflection of the reflection groove produce the dynamic wave reflection effect, the dynamic vision of the person can be utilized to complete the rapid capture of the information at the place, the information that the impact occurs at the place can be rapidly transmitted to the surrounding personnel, and then the subsequent rescue measures and the situation that the irrelevant personnel are killed or injured are further improved.

DETAILED DESCRIPTION

[0042] Example one: please refer to Figures 1-4 The present application provides a technical solution: a direct current double-gun charging pile, comprising a direct current double-gun charging pile 1, a protection mechanism 3 is arranged at the bottom of the direct current double-gun charging pile 1, and the protection mechanism 3 comprises:

[0043] ​​​​​​​​​The base 301 is a square plate structure, a sliding groove 302 is formed in the inner wall of the base 301, a sliding plate 304 is slidably connected to the inner wall of the sliding groove 302 through a sliding block 303, the top of the sliding plate 304 is fixedly connected to the bottom of the direct current double-gun charging pile 1, and the base 301 supports the direct current double-gun charging pile 1;

[0044] The connecting plate 306 is an arc-shaped plate structure, a sponge sleeve 307 is fixedly connected to the outer wall of the connecting plate 306, one end of the connecting plate 306 is fixedly connected to the hinged plate 305, a rotating shaft 315 is fixedly connected to the inner wall of the hinged plate 305, a torsional spring is fixedly connected between the outer wall of the rotating shaft 315 and the sliding plate 304, and the torsional spring functions to reset the rotating shaft 315 after rotation;

[0045] When the vehicle backs up to the direct current double-gun charging pile 1 and charges through the charging gun, if the vehicle backs up too much, the sponge sleeve 307 is touched, the sponge sleeve 307 is pushed upward due to the arc surface after being touched, the connecting plate 306 and the hinged plate 305 in the sponge sleeve 307 are rotated and hinged upward on the rotating shaft 315, the torsional spring between the rotating shaft 315 and the sliding plate 304 is extruded and deformed when the rotating shaft 315 rotates, resistance to rotation of the hinged plate 305 and the sponge sleeve 307 is generated, and buffer braking is given to the vehicle when the vehicle backs up slowly, so that the vehicle owner in the vehicle can timely feel the resistance at the rear, brake in time, and avoid the safety problem of causing impact damage to the direct current double-gun charging pile 1 to cause a fire, meanwhile, the sponge sleeve 307 is wrapped outside the connecting plate 306, the sponge sleeve 307 is made of sponge material, can prevent vehicle collision damage, protect the vehicle from damage, and can also ensure the safety of the direct current double-gun charging pile 1;

[0046] Embodiment two: please refer to Figures 1-11 On the basis of embodiment one, the application provides a technical solution: during the process of backing up the vehicle into the charging parking space, due to the driver's operation error, blocked vision (such as existence of obstacles in the rear of the vehicle, existence of a blind area in the reversing image, etc.) or inaccurate judgment of the distance between the vehicle and the charging pile, etc., the vehicle is extremely easy to collide with the direct current double-gun charging pile when backing up.

[0047] Such a collision accident not only causes damage to the vehicle itself, but more seriously, causes damage to the direct current double-gun charging pile. The direct current double-gun charging pile integrates numerous precise electronic components, such as a charging control module, a power conversion module, a communication module, etc., once directly impacted, strong vibration and impact force can cause the electronic components to loosen and damage, thereby affecting the normal operation of the charging pile, and even causing short circuit, fire, etc. serious safety accidents, threatening the safety of personnel and property in the charging station.

[0048] At the same time, the existing DC double-gun charging pile protection device on the market mostly has single function, can only play a simple physical blocking role, cannot timely remind the driver when the vehicle reverses and approaches, and cannot provide effective buffer protection according to different impact speed and mode of the vehicle, and is difficult to meet the demand of charging pile safety protection in actual use. Therefore, it has important practical significance to develop a protection device that can timely issue an alarm when the vehicle reverses and approaches, and can take targeted buffer measures according to the vehicle impact situation, and effectively protect the DC double-gun charging pile, therefore, one end of the rotating shaft 315 is rotatably connected with the outer wall of the sliding plate 304, the outer wall of the hinged plate 305 is fixedly connected with the telescopic rod 308, one end of the telescopic rod 308 is fixedly connected with the fixed plate 316.

[0049] The fixed plate 316 is fixedly connected with the fixed block 317 at the bottom, one side of the fixed block 317 is fixedly connected with the outer wall of the sliding plate 304, and one side of the fixed plate 316 is fixedly connected with the sponge pad 312.

[0050] The base 301 is fixedly connected with the baffle 311 at the top, one side of the baffle 311 is fixedly connected with the thick telescopic rod 310, one end of the thick telescopic rod 310 is fixedly connected with the vertical plate 309, and the bottom of the vertical plate 309 is fixedly connected with the top of the sliding plate 304.

[0051] The thick telescopic rod 310 is provided with an internal spring, the outer wall of the telescopic rod 308 is provided with a one-way air inlet 314, and the outer wall of the telescopic rod 308 is fixedly connected with a one-way air passage alarm whistle 313; the one-way air passage alarm whistle 313 and the one-way air inlet 314 are both one-way air valves.

[0052] When the sponge sleeve 307 is pushed, the telescopic rod 308 hinged with the hinged plate 305 is pushed synchronously, so that the telescopic rod 308 is retracted, the air in the telescopic rod 308 is squeezed out through the one-way air passage alarm whistle 313 after the telescopic rod 308 is retracted, and a sound is generated through the one-way air passage alarm whistle 313 to remind the driver in the vehicle and the surrounding pedestrians or staff, so that they can be discovered in time or stopped in time by others, preventing the situation of collision of the DC double-gun charging pile 1 due to reversing mistake.

[0053] If the vehicle fails to stop in time and continues to hit the DC double-gun charging pile 1 backward, at this time the hinged plate 305 and the sponge sleeve 307 rotate to the sponge sleeve 307 against the sponge pad 312, the vehicle moves backward by pushing the sponge sleeve 307 and the sponge pad 312 to the sliding plate 304, and squeezes the coarse telescopic rod 310 to retract, and the built-in spring inside the coarse telescopic rod 310 is also squeezed and deformed, and the built-in spring has a large elastic force, which can resist the sliding plate 304 and give a certain buffer, which can effectively prevent the vibration caused by the direct impact of the vehicle from affecting the electronic elements inside the DC double-gun charging pile 1, and the sliding plate 304 with the DC double-gun charging pile 1 can avoid the vehicle by a certain distance, which can buffer the vehicle and relieve the impact force of the vehicle, and the sponge sleeve 307 contacts the vehicle to avoid the direct impact of the DC double-gun charging pile 1 by the vehicle, which protects the DC double-gun charging pile 1 from being impacted and reduces the vibration caused by the impact;

[0054] If the vehicle hits the sponge sleeve 307 at a very fast speed, the hinged plate 305 and the sponge sleeve 307 will not be completely lifted to the sponge pad 312 and will be pushed to move the sliding plate 304 and the DC double-gun charging pile 1 backward, because the air in the telescopic rod 308 squeezed by the lifting of the hinged plate 305 can only be discharged through the one-way air alarm whistle 313, and the caliber of the one-way air alarm whistle 313 is very small, so the exhaust of the one-way air alarm whistle 313 is slow, thereby the contraction speed of the telescopic rod 308 is limited, and the lifting speed of the hinged plate 305 is also limited, so when the vehicle hits the sponge sleeve 307 quickly, the lifting of the sponge sleeve 307 and the hinged plate 305 is blocked, and then the received force is transmitted to the sliding plate 304, which drives the DC double-gun charging pile 1 and the sliding plate 304 to move backward and be buffered by the coarse telescopic rod 310 and the built-in spring inside it, so that when the vehicle approaches slowly, the torsional spring between the shaft 315 and the sliding plate 304 can limit and warn the vehicle through the sponge sleeve 307, and when the vehicle hits the sponge sleeve 307 at a high speed, the built-in spring with a large elastic force inside the coarse telescopic rod 310 is directly used for buffering, and after the coarse telescopic rod 310 is pushed to retract to the maximum, the sponge sleeve 307 will continue to be squeezed upward by the vehicle, and the air pressure inside the telescopic rod 308 will be used to block the subsequent impact of the vehicle that has not been completely resolved, and different buffering measures will be taken according to different impact modes of the vehicle to achieve the maximum buffering effect;

[0055] Example three: please refer to Figures 1-18On the basis of embodiment one and embodiment two, the application provides a technical solution: from the safety angle of the charging pile itself, if the vehicle hits the charging pile due to the operation error of the driver or sudden failure, the strong impact force will directly damage the charging pile shell, causing the internal precision components to loosen, shift or even break, affecting normal operation. In terms of information transmission after the impact and personnel safety protection, the situation is also not optimistic. If the surrounding personnel cannot learn about the impact information in time, in the presence of dangerous situations such as flying debris and electric leakage on the spot, secondary injuries are extremely easy to occur. At the same time, if the staff cannot quickly detect the accident and carry out rescue and repair, the damage to the charging pile will be more serious, the recovery time will be prolonged, the charging of other users will be affected, and potential safety hazards may lead to more serious consequences if not handled in time.

[0056] The existing warning method of the charging pile has obvious limitations. The traditional warning signs and fixed warning lights have certain effect in normal environment, but in the complex scene after the impact, the warning effect is greatly discounted. Static warning signs are difficult to detect in poor light or when blocked, and fixed warning lights may fail due to power failure after impact, and cannot transmit impact information in time. Moreover, these static warning methods are difficult to attract people's attention and cannot meet the warning needs of the sudden dynamic event of vehicle impact. Therefore, there is an urgent need for a new protective device that can not only buffer the impact energy and protect the charging pile, but also timely and eye-catching alert surrounding personnel, therefore, the outer wall of the fixed plate 316 is provided with a warning mechanism 4, the warning mechanism 4 includes a rotating rod 401, one end of the rotating rod 401 is fixedly connected with the outer wall of the rotating shaft 315, the outer wall of the rotating rod 401 is rotatably connected with a swing rod 402, and the bottom of the swing rod 402 is fixedly connected with a counterweight 403.

[0057] The inner wall of the swing rod 402 is provided with a groove 404, the inner wall of the groove 404 is rotatably connected with a rotating rod 405, the outer wall of the rotating rod 405 is rotatably connected with a swing plate 406, and the inner wall of the swing plate 406 is provided with a light reflection groove 408.

[0058] The outer wall of the swing plate 406 is fixedly connected with a short spring 407, one end of the short spring 407 is fixedly connected with the inner wall of the groove 404, and one side of the swing plate 406 is fixedly connected with a connecting strip 409.

[0059] When the sliding plate 304 slides backward with the direct current double-gun charging pile 1, the sliding plate 304 slides in the inner wall of the sliding groove 302 through the slider 303 below. The sudden impact sliding causes the rotating rod 401 and the swing rod 402 on the fixed plate 316 to produce inertial swing, so that the swing rod 402 swings back and forth on the rotating rod 401 and realizes long-time stable swing through the counterweight of the counterweight block 403. The swing of the swing rod 402 and the swing plate 406 in the groove 404 inside the swing rod 402 realize swing and reflect light outward. The setting of the light reflection groove 408 can make the swing plate 406 reflect light, and through the back-and-forth swinging action, the dynamic light reflection reminds the surrounding vehicles and personnel that there is a collision here. Due to the setting of the buffer function, the vehicle collision energy can be absorbed, and the impact sound is also reduced. However, through the swing of the swing rod 402 and the dynamic reflection of the light reflection groove 408, the surrounding vehicles and pedestrians are reminded to quickly move away, and the staff quickly observe and come to rescue and repair in time.

[0060] The swing plate 406 left side in the groove 404 exists a gap, and the connecting strip 409 on the right side of the swing plate 406 closes the right side of the inner wall of the groove 404, so that the swing plate 406 left and right produces air pressure difference in the swing of the swing rod 402, which makes the swing plate 406 on the rotating rod 405 through the elastic force of the short spring 407 to produce back-and-forth rapid forward and reverse rotation, transverse swing and vibration. The vibration can make the light reflection in the light reflection groove 408 produce a quick dynamic wave light reflection effect, which can use the dynamic vision of the human to quickly capture the information at this place, ensure that the information of the collision at this place can be quickly spread to the surrounding personnel, and further improve the subsequent rescue measures and avoid the situation of irrelevant personnel casualties.

[0061] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacement or change according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
