Description
Technical Field
[0001] This utility model belongs to the technical field of charging piles, specifically relating to charging piles with multiple charging devices. Background Technology
[0002] In order to significantly improve the service capacity of charging stations and solve the problem of queuing for charging during peak hours with limited physical space and power infrastructure investment, charging piles with multiple charging devices are often used to charge vehicles, allowing multiple vehicles to use the same charging position at the same time, thus improving efficiency.
[0003] While multi-gun charging stations improve service efficiency and space utilization, the concentration of multiple power modules within a single cabinet significantly increases the power density per unit volume compared to single-gun charging stations. This results in more concentrated and intense heat generation, requiring timely heat dissipation. Insufficient heat dissipation can lead to overheating and derating (reducing output power to protect the equipment) during prolonged high-load operation (simultaneous high-speed charging with dual guns), making it inconvenient to quickly charge vehicles. Utility Model Content
[0004] The purpose of this invention is to provide a charging pile with multiple charging devices, thereby solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A charging pile with multiple charging devices includes a heat dissipation component and a charging pile. Charging cables are installed on both sides of the charging pile, with a charging gun head fixedly connected to the end of each charging cable furthest from the charging pile. A cooling fan is installed inside the left side of the charging pile, and an exhaust plate is fixedly connected inside the right side of the charging pile. An adjustment plate is installed on the left side of the exhaust plate, and an adjustment component that drives its movement is installed on the top of the adjustment plate. Two mounting seats are fixedly connected to the front of the charging pile. A positioning component includes a second tension spring, which is fixedly connected inside the mounting seat. A trapezoidal positioning block is fixedly connected to the end of the second tension spring furthest from the mounting seat. Two positioning grooves are formed on the outside of the charging gun head.
[0006] In a preferred embodiment of this utility model, the adjustment assembly includes a connecting rope, which is fixedly connected to the top of the adjustment plate. Two first tension springs are fixedly connected inside the charging pile. An L-shaped mounting plate is fixedly connected to the end of each of the two first tension springs away from the charging pile. A limiting block is fixedly connected to the side of the L-shaped mounting plate away from the charging gun head. Five rollers are rotatably connected inside the limiting block.
[0007] As a preferred embodiment of this utility model, the five rollers are arranged in an arc shape, and the rollers abut against the connecting rope, which is movably connected to the inner side of the limiting top block.
[0008] As a preferred embodiment of this utility model, the front end of the L-shaped mounting plate abuts against the charging gun head, and the L-shaped mounting plate is slidably connected to the inside of the charging pile.
[0009] In a preferred embodiment of this utility model, the end of the connecting rope away from the adjusting plate is fixedly connected to the charging pile, a counterweight is fixedly connected to the bottom of the adjusting plate, the charging pile has a connecting rope movable cavity inside, and the charging pile and the limiting top block have compression cavities at corresponding positions.
[0010] As a preferred embodiment of this utility model, the adjustment plate has a through groove inside, and the through groove corresponds to the heat dissipation groove inside the exhaust plate.
[0011] In a preferred embodiment of this utility model, a connecting rod is rotatably connected to the bottom end of the trapezoidal positioning block, and a control block is rotatably connected to the end of the connecting rod away from the trapezoidal positioning block. The control block is slidably connected to the inside of the mounting base.
[0012] In a preferred embodiment of this utility model, the trapezoidal positioning block is slidably connected to the inside of the mounting base, and the trapezoidal positioning block is engaged with the inside of the positioning groove.
[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. By using the heat dissipation components and the height control of the adjustment plate via the connecting rope, the overlap rate between the through slot and the heat dissipation slot is controlled, which determines the heat dissipation efficiency of the charging pile. This allows for adjustments to the heat dissipation efficiency based on the usage of the charging pile, avoiding the problem of overheating and derating (reducing output power to protect the equipment) caused by insufficient heat dissipation capacity during long-term high-load (dual-gun simultaneous high-speed charging) operation, which would hinder the fast charging of vehicles.
[0014] 2. The trapezoidal positioning block is inserted into the positioning slot to position the charging gun head through the positioning component. This avoids the problem that after the charging gun head is inserted, it may move outward under the action of the counterweight and the first tension spring, making it unstable to be inserted into the charging pile, or even fall to the ground and be damaged. While positioning and protecting the charging gun head, it also prevents the adjustment plate from shaking after being lifted, thereby preventing external dust from entering the charging pile through the heat dissipation groove of the exhaust plate and causing damage, thus further protecting the charging pile.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0019] Example 1 Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a charging pile with multiple charging devices, including a heat dissipation component, including a charging pile 10. Charging cables 11 are provided on both sides of the charging pile 10. A charging gun head 12 is fixedly connected to the end of the charging cable 11 away from the charging pile 10. A heat dissipation fan 13 is provided inside the left side of the charging pile 10. An exhaust plate 14 is fixedly connected inside the right side of the charging pile 10. An adjustment plate 15 is provided on the left side of the exhaust plate 14. An adjustment component 16 that drives the adjustment plate 15 to move is provided on the top of the adjustment plate 15. Two mounting seats 17 are fixedly connected to the front of the charging pile 10.
[0020] The adjustment plate 15 is raised and lowered by adjusting component 16, thereby reasonably controlling the overlap rate of heat dissipation slot and through slot, and thus adjusting the exhaust volume.
[0021] Furthermore, the adjustment assembly 16 includes a connecting rope 161, which is fixedly connected to the top of the adjustment plate 15. Two first tension springs 162 are fixedly connected inside the charging pile 10. An L-shaped mounting plate 163 is fixedly connected to the end of each of the two first tension springs 162 away from the charging pile 10. A limit block 164 is fixedly connected to the side of the L-shaped mounting plate 163 away from the charging gun head 12. Five rollers 165 are rotatably connected inside the limit block 164.
[0022] Five rollers 165 are arranged in an arc shape, and the rollers 165 abut against the connecting rope 161, which is movably connected to the inside of the limiting top block 164.
[0023] The connecting rope 161 is squeezed by the arc-shaped rollers 165, which reduces wear and prevents damage. At the same time, the lifting and lowering of the adjusting plate 15 is smoother and the adjustment is more convenient.
[0024] Preferably, the front end of the L-shaped mounting plate 163 abuts against the charging gun head 12, and the L-shaped mounting plate 163 is slidably connected to the inside of the charging pile 10. The end of the connecting rope 161 away from the adjusting plate 15 is fixedly connected to the charging pile 10. A counterweight is fixedly connected to the bottom of the adjusting plate 15. The charging pile 10 has an movable cavity for the connecting rope 161. The charging pile 10 and the corresponding position of the limiting top block 164 have extrusion cavities. The adjusting plate 15 has a through groove 166 inside, and the through groove 166 corresponds to the heat dissipation groove inside the exhaust plate 14.
[0025] It should be noted that by controlling the height of the adjusting plate 15 through the connecting rope 161, the overlap rate between the through groove 166 and the heat dissipation groove is controlled, which determines the heat dissipation efficiency of the charging pile 10, making it convenient to adjust the heat dissipation efficiency accordingly based on the usage of the charging pile 10.
[0026] When in use, if neither of the two charging heads 12 is inserted into the charging pile 10, the charging heads 12 press inward against the L-shaped mounting plate 163, compressing the first tension spring 162. At this time, the five rollers 165 inside the limiting top block 164 press against the connecting rope 161, causing the connecting rope 161 to be pressed into the compression cavity corresponding to the limiting top block 164 (e.g., Figure 3 , Figure 4(As shown in the diagram), the connecting rope 161 lifts the adjusting plate 15. At this time, the lower end of the bottom counterweight of the adjusting plate 15 is not in contact with the ventilation duct. At this time, the internal through groove 166 of the adjusting plate 15 is misaligned with the internal heat dissipation groove of the exhaust plate 14, thus making the heat dissipation gap smaller. This prevents dust and other impurities from entering the charging pile 10 through the heat dissipation groove of the exhaust plate 14 when the charging pile 10 is not in use, causing damage to the parts. When any charging gun head 12 is used, the charging gun head 12 is disengaged from the charging pile 10. At this time, the charging gun head 12 no longer presses against the L-shaped mounting plate 163. At this time, the first tension spring 162 rebounds, causing the limit top block 164 and roller 165 to reset, no longer pressing against the connecting rope 161. This causes the adjusting plate 15 to descend under the action of the bottom counterweight. At this time, the overlapping area of the through groove 166 and the internal heat dissipation groove of the exhaust plate 14 increases, thus increasing the heat dissipation gap. The increased size accelerates heat dissipation. Simultaneously, when the charging gun head 12 is plugged into the vehicle for charging, the rotation speed of the fan blades inside the cooling fan 13 is increased to dissipate heat from the inside of the charging pile 10 in a timely manner. When both charging gun heads 12 are in use, the two limit blocks 164 no longer squeeze the connecting rope 161. At this time, the bottom end of the counterweight strip at the bottom of the adjusting plate 15 contacts the ventilation duct. At this time, the through groove 166 and the heat dissipation groove of the exhaust plate 14 are completely overlapped, which further enhances the heat dissipation efficiency. At the same time, the rotation speed of the fan blades inside the cooling fan 13 is further increased, so that the heat dissipation efficiency of the charging pile 10 can be adjusted according to the usage. This avoids the problem that insufficient heat dissipation capacity will cause the charging pile 10 to overheat and dredge (reduce the output power to protect the equipment) when it is running under high load for a long time (simultaneous high-speed charging of both guns), thus making it inconvenient to fast charge the vehicle.
[0027] It should be noted that when neither of the two charging heads 12 is in use, the through slot 166 and the heat dissipation slot in the adjustment plate 15 are misaligned, which reduces heat loss in the charging pile 10 in cold weather, thereby avoiding the risk of the parts inside the charging pile 10 freezing and protecting the charging pile 10.
[0028] Example 2 Reference Figure 1 , Figure 6 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a positioning component, including a second tension spring 20. The second tension spring 20 is fixedly connected inside the mounting base 17. A trapezoidal positioning block 21 is fixedly connected to the end of the second tension spring 20 away from the mounting base 17. Two positioning grooves 22 are formed on the outside of the charging gun head 12. A connecting rod 23 is rotatably connected inside the bottom end of the trapezoidal positioning block 21. A control block 24 is rotatably connected to the outside of the end of the connecting rod 23 away from the trapezoidal positioning block 21. The control block 24 is slidably connected vertically inside the mounting base 17, and the trapezoidal positioning block 21 is slidably connected horizontally inside the mounting base 17. The trapezoidal positioning block 21 is engaged inside the positioning grooves 22. In use, when the charging gun head 12 is inserted into the charging pile 10, the charging gun head 12 first passes through the mounting base 17 and contacts two symmetrically arranged trapezoidal positioning blocks 21 inside the mounting base 17. As the charging gun head 12 moves, the two trapezoidal positioning blocks 21 separate to both sides, compressing the second tension spring 20. After the charging gun head 12 is inserted into the charging pile 10, the positioning groove 22 corresponds to the trapezoidal positioning block 21. The trapezoidal positioning block 21 returns to its original position under the rebound action of the second tension spring 20, thus inserting into the positioning groove 22, thereby securing the charging gun head. Positioning the charging gun head 12 ensures that it will not move after being inserted into the charging pile 10. This prevents the charging gun head 12 from moving outward and failing to be stably inserted into the charging pile 10 under the action of the counterweight and the first tension spring 162, or even falling to the ground and being damaged. While positioning and protecting the charging gun head 12, it also ensures that the position of the adjusting plate 15 is fixed after being lifted, preventing it from shaking. This prevents external dust from entering the charging pile 10 through the heat dissipation groove of the exhaust plate 14 and causing damage, thus further protecting the charging pile 10.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
