Technical Field

[0001] The invention relates to an outdoor waterproof charging pile. Background Art

[0002] A charging pile is a device used to charge electric vehicles. Charging piles mainly include slow charging and fast charging. The voltage of fast charging is higher and the heat generated by the equipment is higher when it is running. Therefore, the fast charging piles in the prior art are equipped with multiple sets of fans on both sides, and the fans exhaust air to the outside of the charging pile.

[0003] In actual operations, we found that since fast charging piles are commercial charging piles, they are usually installed outdoors and only rely on awnings for waterproofing. When encountering bad weather, this side direct air outlet method is very easy to get water in, and water ingress will cause the cooling fan to malfunction.

[0004] Traditional technology requires manual operation, and if the gun is not inserted firmly, it is easy to cause the charging gun to malfunction after it falls. In addition, the charging gun is heavy, and manual insertion and removal is difficult for users with less strength.

[0005] Based on the above problems, we designed an outdoor waterproof charging pile that can achieve waterproof exhaust and automatic gun insertion. Summary of the invention

[0043] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An outdoor waterproof charging pile shown includes an electrical part 1, a charging gun 3 connected to the electrical part 1 through a cable 2, and an intelligent controller 4 connected to the electrical part 1, and also includes:

[0044] A cabinet structure 5, in which the electrical part 1 is stored, and the cable 2 passes through the cabinet structure 5 and is connected to the charging gun 3;

[0045] The back plate structure 6 is installed at the rear end of the cabinet structure 5. The circulating water passes through the back plate structure 6, and the air enters the cabinet structure 5 through the back plate structure 6. The air enters the cabinet structure 5 and is cooled by water.

[0046] The gun plug terminal 7 is embedded in both sides of the cabinet structure 5. The gun plug terminal 7 is electrically connected to the intelligent controller. The charging gun 3 is inserted into the gun plug terminal 7 when it is idle.

[0047] The electric plug-in device 8 is installed on both sides of the cabinet structure 5 and is located above the gun plug terminal 7. The charging gun 3 is inserted into and removed from the gun plug terminal 7 through the electric plug-in device 8; the electric plug-in device 8 is controlled by the intelligent controller 4. When the user scans the code to charge, the electric plug-in device 8 pulls the charging gun 3 out of the gun plug terminal 7; when the user finishes charging and the charging gun 3 is separated from the vehicle, the intelligent controller 4 reminds the user to return the charging gun 3 to its original position. After the charging gun 3 is returned to its original position, the intelligent controller 4 controls the electric plug-in device 8 to reset, so that the charging gun 3 is reinserted into the gun plug terminal 7, and the intelligent controller 4 completes the electricity bill settlement; when the charging gun 3 is not correctly returned to its original position, the intelligent controller 4 notifies the charging user and the administrator at the operation end, and the background of the intelligent controller 4 does not settle the electricity bill, but only keeps the account, and maintains the frequency of background notifications to the charging user.

[0048] In the above technical solution, the user only needs to remove the charging gun 3 from the electric control plug-in device 8. Compared with the traditional manual plug-in, this operation method is more labor-saving. At the same time, it also solves the problem that the manual plug-in is not firm in the traditional technology, resulting in water ingress after loosening.

[0049] When the user has completed charging and has not correctly returned the charging gun 3, the intelligent controller 4 frequently notifies the user's client through the 4G or 5G communication network through the background. The notification frequency is gradually reduced. In the early stage, notifications are made every 15 seconds to help the user reset the charging gun 3 before driving away. The notification time is maintained for 3 minutes, and then the frequency begins to be reduced to once a minute.

[0050] If the intelligent controller 4 is not properly reset for more than 10 minutes, the administrator can reset it on site.

[0051] When the next customer is charging and finds that the charging gun is not returned to its place, he can directly connect the charging gun 3 to the vehicle. After the connection is completed, the intelligent controller 4 settles the charging order of the previous user and imposes a fine or warning. If the gun is not plugged in for more than 3 times, the user will be added to the abnormal list. The next time the code is scanned, the user will not be able to activate the charging gun of this station.

[0052] See also Figure 3 , Figure 5 and Figure 6As shown, the cabinet structure 5 includes a cabinet 51, a bottom plate 52 and a front cabinet plate 53; a channel 54 is horizontally passed through the side of the cabinet 51, and a partition plate 55 is installed inside the cabinet 51 above the channel 54. A cooling fan 56 for exhausting air toward the channel 54 is installed on the plate surface of the partition plate 55. The front and rear ends of the cabinet 51 are both provided with openings. The front cabinet plate 53 is closed and installed at the front of the cabinet 51. The back plate structure 6 is closed and installed at the cabinet 51. At the rear of the cabinet 51, installation slots 57 are opened on both sides of the cabinet 51, and the electric control plug-in device 8 is installed in the installation slots 57; the plug terminals 7 are installed on both sides of the cabinet 51 and are located below the electric control plug-in device 8; a cross frame 58 is clamped in the cabinet 51, and the electrical part 1 is installed on the top of the cross frame 58, and the rear end surface of the electrical part 1 is in contact with the backplane structure 6; the cable 2 passes through the partition plate 55 and comes out from the channel 54.

[0053] In the above technical solution, a transversely penetrating channel 54 is designed, and the heat dissipation of the cabinet 51 is carried out by a cooling fan 56 at the partition plate 55 .

[0054] The cooling fan 56 is hidden in the channel 54 and is located on the upper part of the partition plate 55, so it can avoid water ingress on rainy days and still maintain normal heat dissipation on rainy days.

[0055] See also Figure 7 and Figure 8 As shown, the backplane structure 6 includes a backplane body 61, an inner frame 62 is welded inside the backplane body 61, a water cavity 63 is formed inside the inner frame 62, a rear cover plate 65 is installed at the end of the backplane body 61 away from the cabinet 51, and the rear cover plate 65 is glued at the position where it contacts the inner frame 62 to form a seal, a water inlet pipe 66 connected to the inner frame 62 is installed on the top of the backplane body 61, and a water outlet pipe 67 connected to the water cavity 63 is installed on the board surface of the rear cover plate 65; an air duct 68 is formed between the outer side of the inner frame 62 and the backplane body 61, and an air cavity 69 is formed inside the backplane body 61 below the inner frame 62, an opening is provided near the lower position of the rear cover plate 65, and a lower cover plate 610 is detachably installed at the opening, an air inlet groove 611 is provided on the board surface of the lower cover plate 610, and a penetrating air inlet hole 612 is provided at the upper end of the air duct 68.

[0056] In the above technical solution, the water chamber 63 is connected in series in the circulating water circuit through the water inlet pipe 66 and the water outlet pipe 67 .

[0057] When the cooling fan 56 is working, it drives air to enter from the air cavity 69, and then enters the cabinet 51 from the air inlet 612 through the air duct 68. This air intake method can reduce the inlet air temperature when the temperature is high in summer, and then cooperate with the cooling fan 56 to smoothly remove the heat accumulated inside the cabinet 51.

[0058] Furthermore, the back plate body 61 itself is sealed at the rear end surface of the cabinet 51 , and the heat inside the cabinet 51 is absorbed during the circulation of water.

[0059] Therefore, the device only needs to use a single cooling fan 56 for exhaust to meet the heat dissipation needs.

[0060] See also Figure 8 As shown, a heat dissipation contact surface 64 is formed on the end of the back plate body 61 facing the cabinet 51 . The heat dissipation contact surface 64 is located on the inner side of the inner frame 62 , and contacts the electrical part 1 through the heat dissipation contact surface 64 .

[0061] A heat-conducting material is applied between the heat dissipation contact surface 64 and the electrical part 1 , so that the heat generated by the electrical part 1 can be smoothly absorbed by the heat dissipation contact surface 64 .

[0062] See also Figure 8 As shown, slide grooves 613 are symmetrically arranged inside the back plate body 61 , and a filter element 614 is inserted between the slide grooves 613 on both sides. The filter element 614 corresponds to the lower cover plate 610 , and the filter element 614 is located above the air inlet groove 611 .

[0063] This technical solution is mainly to filter the incoming air to avoid equipment damage caused by the accumulation of particles inside the cabinet 51.

[0064] The filter element 614 can be pulled out for replacement, and when replacing, the cover plate 610 needs to be removed.

[0065] See also Fig. 9 , Fig.10 and Fig.11As shown, the electric control plug-in device 8 includes a device box 81 and a servo motor 82. The device box 81 is installed in the installation slot 57. A lead screw 83 is rotatably installed in the device box 81. A bearing is provided between the lead screw 83 and the device box 81. The servo motor 82 is installed at the end face of the device box 81 and is connected to drive the lead screw 83. The servo motor 82 is located inside the cabinet 51 after installation. Two guide rods 84 are arranged in parallel in the device box 81. The guide rods 84 are parallel to the lead screw 83. A strip groove 85 is arranged at the bottom of the device box 81. The strip groove 85 corresponds to the guide rod 84. A sliding block 86 is provided between the two guide rods 84. The middle of the sliding block 86 A lead screw nut 87 cooperating with the lead screw 83 is processed at the lower position, an L-shaped hanging plate 88 is set at the bottom of the sliding block 86, a positioning column 89 is installed on the scraper 88, and the upper end of the positioning column 89 is processed to form a conical guide portion 810, and the diameter of the guide portion 810 gradually decreases upward, and a hanging rod 331 is installed on the top of the charging gun 3, and positioning holes 332 cooperating with the positioning column 89 are processed at both ends of the hanging rod 331; a visual camera is installed at the bottom of the device box 81, and the visual camera is connected to the intelligent controller 4. When the visual camera captures that the charging gun is located on the hanging plate 88, the servo motor 82 is controlled to move through the intelligent controller 4, and the lead screw 83 rotates and drives the charging gun 3 to move inward to be inserted into the gun terminal 7.

[0066] In the above technical solution, the servo motor 82 provides power to drive the lead screw 83 to rotate, and the rotation of the lead screw 83 drives the sliding block 86 to slide along the guide rod 84, thereby completing the action of inserting the charging gun 3 into the gun terminal 7 and completing the action of pulling the charging gun 3 out of the gun terminal 7.

[0067] Through the cooperation between the scraper rod 331 and the hanging plate 88, the position of the gun plug terminal 7 when returning to its original position is accurate, ensuring that the insertion depth is sufficient to avoid loosening and water ingress.

[0068] The electric insertion and extraction of the gun eliminates the need for manual operation. Especially for female users with less strength, this design is more labor-saving and greatly reduces equipment damage caused by shaking the gun.

[0069] See also Fig. 9 and Fig.11 As shown, a through hole is processed at the bottom of the device box 81, and a drying fan 811 is installed at the through hole. When the gun terminal 7 moves to the bottom of the drying fan 811, the servo motor 82 stops, and the intelligent controller 4 controls the drying fan 811 to operate at a high speed, and the drying fan 811 blows away the moisture on the surface of the charging gun 3.

[0070] The above technical solution is mainly aimed at the case where, after the charging gun 3 is separated from the vehicle body, if the weather is bad, water will inevitably adhere to the charging gun 3, which may cause a malfunction. Therefore, in the above technical solution, an air drying fan 811 is designed to blow air to remove water before the charging gun 3 is fully inserted into the gun terminal 7, so as to keep the surface of the charging gun 3 as dry as possible.

[0071] See also Fig.11 As shown, an air inlet cover 812 is installed at the upper end of the air-drying fan 811 , and the air inlet cover 812 is connected to an air inlet pipe 813 , and the air inlet pipe 813 passes through the equipment box 81 and extends into the cabinet 51 .

[0072] In the above technical solution, the wind force of the air-drying fan 811 comes from the inside of the cabinet. In this way, the heat inside the cabinet 51 can be discharged, and this part of the discharged heat can also be used to dry the charging gun 3.

[0073] See also Figure 7 As shown, side panels 881 are provided at both sides of the bottom of the device box 81 , and the side panels 881 are welded and fixed to the cabinet 51 , and the gun terminal 7 is located between the two side panels 881 .

[0074] The side plate 881 is mainly provided to shield and protect the gun terminal 7 .

[0075] At the same time, the side panel 881 can also increase the stability of the device box 81 after it is fixed.

[0076] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
