Description

Technical Field

[0001] This invention relates to the field of charging pile technology, specifically a convenient mobile charging pile. Background Technology

[0002] Charging piles function similarly to gas pumps at gas stations. They can be fixed to the ground or walls and installed in public buildings (such as public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging plug to provide charging services for electric vehicles. Charging piles generally provide two charging methods: regular charging and fast charging. Users can use a specific charging card to swipe on the human-machine interface provided by the charging pile to perform operations such as selecting the charging method, charging time, and printing cost data. The charging pile display screen can also display data such as charging amount, cost, and charging time.

[0003] Most existing charging stations are fixed in specific locations, which cannot meet the charging needs in different environments. However, existing mobile charging stations still have the following problems in actual use:

[0004] The patent number "CN201721740754.6" discloses a portable charging pile. When in use, through improvements to the device body and the coordinated use of the display screen, control panel, card reader, output interface and input interface, the charging pile can be moved, expanding the scope of use of the charging pile, which well meets the user's needs, improves work efficiency and facilitates user use. However, the device cannot be rainproof during use. Rain usually contains sulfides, metal particles, dust and other substances, which corrode the charging pile body during long-term use, resulting in a significant reduction in service life.

[0005] A Chinese patent discloses a portable charging pile (authorization announcement number CN222451975U). This patented technology is equipped with a rainproof mechanism to protect the device from rain during use, preventing corrosion from rain over long-term use and thus avoiding a shortened lifespan. The included cooling mechanism can cool the charging pile body when it generates heat during use, preventing the battery from remaining in an overheated state for a long time and reducing its lifespan. The filter screen allows airflow inside the charging pile body, preventing dust and impurities from the outside air from entering the charging pile body.

[0006] However, it has certain drawbacks: although the rainproof mechanism can prevent rainwater from directly impacting the charging pile body, in extreme weather or when the wind direction changes, rainwater may still bypass the rainproof mechanism and directly contact the charging pile body, and then enter the interior of the charging pile body through the filter, causing short circuits or component aging inside the charging pile body. Summary of the Invention

[0007] The purpose of this invention is to provide a convenient mobile charging station to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A convenient mobile charging pile includes a charging pile body and a charging gun connected to the charging pile body. The lower surface of the charging pile body is fixed with four corners of a universal wheel, and a support plate is fixed to the upper part of the rear surface of the charging pile body. A support rod is fixed to the upper surface of the charging pile body, and a rain shield is fixed to the upper end of the support rod.

[0010] A filter plate connected to the interior of the charging pile body is fixedly connected to the front surface of the charging pile body, and a fan connected to the filter plate is fixedly connected to the interior front surface of the charging pile body.

[0011] The front surface of the charging pile body is fixed with L-shaped sliding plates on both the left and right sides of the filter plate. The lower end of the L-shaped sliding plate is fixed with a stop block, and the inside of the L-shaped sliding plate is movably connected with a slider. A protective cover is fixed between the two sliders. A support block is fixed to the lower end of the front surface of the protective cover. A rain sensor is fixed to the upper surface of the support block. An elastic block is embedded and fixed to the lower end of the rear surface of the protective cover.

[0012] The front surface of the charging pile body is provided with a winding mechanism that drives the protective cover to rise and fall, located above the protective cover.

[0013] The front surface of the protective cover, located above the support block, and the interior of the protective cover are both equipped with a sealing mechanism.

[0014] As a further embodiment of the present invention: the winding mechanism includes a fixed plate, a fixed cover is fixedly connected to the front surface of the fixed plate, and a first motor is fixedly connected to the front surface of the fixed plate inside the fixed cover. A winding rod is fixedly connected to the output end of the first motor, and a winding rope is wound around the outside of the winding rod.

[0015] As a further embodiment of the present invention: the sealing mechanism includes a C-shaped plate, a connecting cover is fixedly connected to the front surface of the C-shaped plate, and a second motor is fixedly connected to the front surface of the C-shaped plate inside the connecting cover. A threaded rod is fixedly connected to the output end of the second motor, a threaded tube is threadedly connected to the external thread of the threaded rod, a connecting rod is fixedly connected to the rear end of the threaded tube, and a connecting frame is fixedly connected to the external thread of the connecting rod.

[0016] As a further embodiment of the present invention: the charging gun is wrapped around the outside of the support plate.

[0017] As a further embodiment of the present invention: the rear surface of the protective cover is movably fitted to the front surface of the charging pile body, and the front end of the support block is tilted downward.

[0018] As a further embodiment of the present invention: the rear end of the fixing plate is fixedly connected to the front surface of the charging pile body, the winding rope movably passes through the lower surface of the fixing plate, and one end of the winding rope is fixedly connected to the upper surface of the protective cover.

[0019] As a further embodiment of the present invention: the rear end of the C-shaped plate is fixed to the front surface of the protective cover, the threaded tube movably penetrates the front surface of the protective cover, and the connecting rod is located inside the protective cover.

[0020] As a further embodiment of the present invention, the outer surface of the connecting frame is movably fitted to the inner surface of the protective cover.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention facilitates the movement of the charging pile by using casters, prevents rainwater from directly impacting the charging pile body by using a rain shield, dissipates heat from the interior of the charging pile body by using a fan, and prevents dust and impurities from the outside air from entering the interior of the charging pile body by using a filter plate.

[0023] 2. The present invention is equipped with a winding mechanism. When the rain sensor on the surface of the protective cover detects rain, the first motor in the winding mechanism drives the winding rod to rotate and lower the winding rope, so that the protective cover descends and covers the outside of the filter plate, thus preventing rainwater from entering the interior of the charging pile body through the filter plate.

[0024] 3. The present invention has a sealing mechanism. After the protective cover is put on the outside of the filter plate, the second motor in the sealing mechanism drives the threaded rod to rotate, which drives the connecting frame to be put on the outside of the filter plate and fit against the charging pile body. This prevents rainwater from entering the inside of the protective cover through the fit between the charging pile body and the protective cover, thus improving the sealing performance of the protective cover.

Detailed Implementation

[0033] Please see Figures 1-3 In this embodiment of the invention, a convenient mobile charging pile includes a charging pile body 1 and a charging gun 2 connected to the charging pile body 1. Universal wheels 3 are fixed to the four corners of the lower surface of the charging pile body 1, and a support plate 4 is fixed to the upper end of the rear surface of the charging pile body 1. The charging gun 2 is wrapped around the outside of the support plate 4. A support rod 5 is fixed to the upper surface of the charging pile body 1, and a rain shield 6 is fixed to the upper end of the support rod 5.

[0034] A filter plate 7 connected to the interior of the charging pile body 1 is fixedly connected to the front surface of the charging pile body 1, and a fan 8 connected to the filter plate 7 is fixedly connected to the interior front surface of the charging pile body 1.

[0035] The main body 1 of the charging pile is equipped with an external power connection port;

[0036] The omnidirectional wheel 3 facilitates the movement of the charging pile body 1, and the omnidirectional wheel 3 is equipped with a brake so that it can be locked when movement is not required;

[0037] The rain shield 6 serves to block rain and prevent rainwater from directly impacting the main body 1 of the charging pile;

[0038] Fan 8 is used to dissipate heat from the interior of the charging pile body 1;

[0039] The filter plate 7 is used to prevent external dust and impurities from entering the interior of the charging pile body 1; the filter plate 7 is fixed to the charging pile body 1 by bolts.

[0040] exist Figures 2-6In the charging pile body 1, L-shaped sliding plates 9 are fixedly attached to both the left and right sides of the filter plate 7 on the front surface. A stop block 10 is fixedly attached to the lower end of each L-shaped sliding plate 9, and a slider 11 is movably connected inside the L-shaped sliding plate 9. A protective cover 12 is fixedly attached between the two sliders 11. The rear surface of the protective cover 12 movably fits against the front surface of the charging pile body 1. A support block 13 is fixedly attached to the lower end of the front surface of the protective cover 12. The front end of the support block 13 is tilted downwards. A rain sensor 14 is fixedly attached to the upper surface of the support block 13. An elastic block 15 is embedded and fixedly attached to the lower end of the rear surface of the protective cover 12. A winding mechanism 16 is provided above the protective cover 12 to drive the protective cover 12 to rise and fall. The winding mechanism 16 includes a fixed plate 17. The rear end of the fixed plate 17 is fixed to the front surface of the charging pile body 1. A fixed cover 18 is fixed to the front surface of the fixed plate 17. A first motor 19 is fixed to the front surface of the fixed plate 17 inside the fixed cover 18. A winding rod 20 is fixed to the output end of the first motor 19. A winding rope 21 is wound around the outside of the winding rod 20. The winding rope 21 moves through the lower surface of the fixed plate 17. One end of the winding rope 21 is fixed to the upper surface of the protective cover 12.

[0041] The protective cover 12 is preferably made of stainless steel and is heavy enough; the horizontal length of the protective cover 12 is greater than the horizontal length of the filter plate 7.

[0042] The fan 8, rain sensor 14, and first motor 19 are all electrically connected to the external control system, which is installed inside the charging pile body 1.

[0043] The working principle of the rain sensor 14 is to determine whether it is raining by detecting the conductivity of water droplets. It uses the change in conductivity between two electrodes to measure the presence of water droplets. There is an air gap between the two electrodes, which is normally an open circuit. When a water droplet comes into contact with the electrode, the conductivity of the water droplet causes current to flow through the water droplet to form a current loop, thereby changing the resistance value between the electrodes, which in turn changes the voltage drop across them, thus generating a control signal.

[0044] The first motor 19 is equipped with a brake, meaning that the motor shaft cannot rotate after power is cut off, and the first motor 19 is connected to the forward and reverse circuit.

[0045] Rotating the winding rod 20 will release the winding rope 21, and the protective cover 12 will descend until it covers the outside of the filter plate 7, preventing rainwater from entering the interior of the charging pile body 1 through the filter plate 7.

[0046] The elastic block 15 is preferably made of rubber, which deforms when it comes into contact with the filter plate 7.

[0047] exist Figures 2-5 and Figure 7In the middle: The front surface of the protective cover 12, above the support block 13, and the interior of the protective cover 12 are jointly provided with a sealing mechanism 22. The sealing mechanism 22 includes a C-shaped plate 23. The rear end of the C-shaped plate 23 is fixed to the front surface of the protective cover 12. A connecting cover 24 is fixed to the front surface of the C-shaped plate 23. A second motor 25 is fixed to the front surface of the C-shaped plate 23 inside the connecting cover 24. A threaded rod 26 is fixed to the output end of the second motor 25. A threaded tube 27 is threaded to the outside of the threaded rod 26. The threaded tube 27 movably penetrates the front surface of the protective cover 12. A connecting rod 28 is fixed to the rear end of the threaded tube 27. The connecting rod 28 is located inside the protective cover 12. A connecting frame 29 is fixed to the outside of the connecting rod 28. The outer surface of the connecting frame 29 movably fits against the inner surface of the protective cover 12.

[0048] The second motor 25 is electrically connected to the external control system;

[0049] The second motor 25 is equipped with a brake, meaning that the motor shaft cannot rotate after power is cut off, and the second motor 25 is connected to the forward and reverse circuit.

[0050] The forward and reverse rotation of the threaded rod 26 can cause the threaded tube 27 to move forward or backward. When it moves backward, it drives the connecting frame 29 to move backward, so that the connecting frame 29 fits tightly against the front surface of the charging pile body 1, which improves the sealing performance of the protective cover 12 and prevents rainwater from flowing into the interior of the protective cover 12 from between the charging pile body 1 and the protective cover 12.

[0051] The connecting rod 28 is relatively thin. When the connecting frame 29 is attached to the charging pile body 1 and sleeved on the outside of the filter plate 7, the connecting rod 28 is very close to the filter plate 7, but does not contact it.

[0052] The working principle of this invention is as follows: The operator moves the charging station to the desired location using the casters 3. During use, the user inserts the charging gun 2 into the vehicle's charging port. After charging, the gun is removed and wrapped around the outside of the support plate 4. During use, the control system activates the fan 8 to dissipate heat from the inside of the charging station body 1, while the filter plate 7 prevents external dust and impurities from entering the charging station body 1. When it rains, the rain shield 6 protects the charging station body 1. When raindrops fall onto the rain sensor 14, the rain sensor 14 transmits a sensing signal to the external control system, which then first controls... When the blower 8 stops running, the first motor 19 and the second motor 25 are controlled to operate sequentially. The first motor 19 drives the winding rod 20 to rotate and release the winding rope 21, causing the protective cover 12 to descend until it covers the outside of the filter plate 7 and fits against the upper surface of the stop block 10. The first motor 19 then stops operating. The second motor 25 drives the threaded rod 26 to rotate, causing the threaded tube 27 to drive the connecting rod 28 to move backward until the connecting frame 29 covers the outside of the filter plate 7 and fits against the front surface of the charging pile body 1. The protective cover 12 and the connecting frame 29 protect the filter plate 7, preventing rainwater from entering the interior of the charging pile body 1 through the filter plate 7.
