Description

Technical Field

[0001] The present invention relates to the technical field of power management, and more specifically, to an intelligent distribution device. Background Art

[0002] With the popularization of electric vehicles, the construction of a charging pile network has become a key infrastructure to ensure the normal operation of electric vehicles. The charging pile network not only needs to meet diverse charging demands but also strike a balance between grid stability and energy utilization efficiency. Generally, charging piles provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe on the man-machine interaction operation interface provided by the charging pile to perform operations such as corresponding charging methods, charging time, and printing of fee data. The display screen of the charging pile can display data such as the charging amount, fee, and charging time. During this process, a power distribution device is required to distribute power and regulate voltage to ensure stable charging of the electrical appliances.

[0003] For the power distribution device of the existing charging piles, all power distribution unit boards, positive copper bars, negative copper bars, and accessories are fixed on the same main frame. When assembling, the main frame with components is installed inside the charging pile. Since the power distribution device needs to dissipate heat during use, the entire main frame is set to be open to meet the heat dissipation requirements of the components thereon. When the power distribution device is in a state of low heat dissipation or stops dissipating heat, its open structure design reduces the dust-proof performance of the devices.

A thermal expansion liquid is stored in the liquid storage box. A piston plate is slidably connected in the liquid storage box, and a lifting rod is fixedly connected to the piston plate.

[0010] In a preferred embodiment, one end of the lifting rod passes through the liquid storage box and is fixedly connected to the traction rod. A guide rod is fixedly connected to the outer side of the housing, and the traction rod is slidably connected to the guide rod.

[0011] In a preferred embodiment, the first gear transmission assembly includes a support frame one which is fixedly connected to the outer side of the housing. A gear one is rotatably connected to the support frame one. A rack one and a rack two are respectively meshed with the gear one. A sliding frame is fixedly connected to the outer side of the housing. The rack one is fixedly connected to one end of the traction rod, and the rack two is slidably connected to the sliding frame. One end of the rack two is fixedly connected to the inner wall of the dust cover.

[0012] In a preferred embodiment, fixing frames are fixedly connected to both sides of the housing.

[0015] Technical effects and advantages of the present invention: For this intelligent distribution device, by providing a pair of dust covers on the outer side of the housing, when the components inside the housing are working, the thermal lifting structure can absorb the working heat of the components and provide a thrust force. This thrust force can cause the dust covers on the housing to open outwards, and the opened dust covers can enable the conductive union structure to achieve the purpose of a heat dissipation switch, so as to timely control the cooling fan to perform a heat dissipation response. Similarly, when the heat absorbed by the thermal lifting structure cannot provide a thrust force, the dust covers can close to dust-proof the housing. Therefore, with the purpose of flexibly exposing the heat dissipation opening of the fan installation panel, the components inside the housing can be flexibly dust-proof protected.

[0016] For this intelligent distribution device, in order to ensure an effective opening and closing degree of the dust covers during heat dissipation of the components, a thermal lifting structure and a gear transmission assembly one can be respectively provided corresponding to each dust cover. Considering the uneven distribution of the temperature around the housing, when the two thermal lifting structures sense temperature simultaneously, the one with the strongest temperature sensing can be preferentially used to provide the opening and closing power for the dust cover, so as to ensure the effectiveness of the heat dissipation opening of the dust cover.

[0017] For this intelligent distribution device, by providing a gear transmission assembly two, since the dust covers are a pair and are distributed at the upper and lower positions of the housing, when one of the dust covers is subjected to the thrust or pull force provided by the thermal lifting structure, the gear transmission assembly two can drive the pair of dust covers to move synchronously, so that the pair of dust covers can open and close synchronously and relatively.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Referring to Figures 1-9 , the present invention provides an intelligent distribution device for connecting to the main controller of a charging pile, including a housing 1. Fan mounting panels 2 are provided on both sides of the housing 1, and a cooling fan 3 is arranged inside the housing 1. The cooling fan 3 is installed on one side of the fan mounting panel 2 by screws.

[0022] The fan mounting panel 2 is provided with heat dissipation openings. Since the two fan mounting panels 2 are distributed on both sides of the housing 1, the corresponding cooling fans 3 on the two fan mounting panels 2 can respectively perform the functions of drawing air into the housing 1 and blowing air outside the housing 1, so that the heat inside the housing 1 can be conveniently discharged in time.

[0023] In this embodiment: Inside the housing 1, a first power distribution board 7 and a second power distribution board 8 are provided. On the second power distribution board 8, a distribution board controller 9 is provided. At the inner top and inner bottom of the housing 1, an upper insulating bracket 5 and a lower insulating bracket 12 are fixedly connected respectively. The first power distribution board 7 and the second power distribution board 8 are fixedly connected between the upper insulating bracket 5 and the lower insulating bracket 12. Between the upper insulating bracket 5 and the lower insulating bracket 12, an output loop positive copper busbar group 6 and an output loop negative copper busbar group 11 are provided. At the top of both the first power distribution board 7 and the second power distribution board 8, positive output terminals are provided, and at the bottom of both the first power distribution board 7 and the second power distribution board 8, negative output terminals are provided. The corresponding positive output terminals on the first power distribution board 7 and the second power distribution board 8 are screw-connected through the output loop positive copper busbar group 6, and the corresponding negative output terminals on the first power distribution board 7 and the second power distribution board 8 are screw-connected through the output loop negative copper busbar group 11.

[0024] Insulating blocks are installed on both the upper insulating bracket 5 and the lower insulating bracket 12 by screws, and a card slot is provided on the insulating block. This card slot can be used to clamp and install the first power distribution board 7 and the second power distribution board 8 respectively. The output loop positive copper busbar group 6 and the output loop negative copper busbar group 11 can connect the output loops on the first power distribution board 7 and the second power distribution board 8. The first power distribution board 7 and the second power distribution board 8 can be integrated to form a power distribution board assembly. The power distribution board assembly is used to distribute the charging power of the charging pile. The distribution board controller 9 selects a high-performance microprocessor.

[0025] The distribution board controller 9 establishes a stable and high-speed data connection with each power distribution board through the CAN bus or RS485 communication protocol, realizing precise control and real-time status monitoring of the power distribution board assembly. The distribution board controller 9 is responsible for collecting the instructions sent by the charging pile controller and executing the distribution strategy. The power distribution board assembly undertakes the specific power distribution task. Each charging module of the charging pile corresponds to a power distribution board assembly, and the power distribution board assembly adopts a full matrix twelve-way output layout. Its internal circuit consists of a series of high-performance power switch elements. Under the instructions of the control system, these switch elements accurately control the on-off state to precisely distribute the power to different output channels to meet the power requirements of each charging terminal. The power switch elements select insulated gate bipolar transistors with low on-resistance, high switching speed, and high breakdown voltage capabilities. Such elements can perfectly adapt to the harsh working environment of high power and large current of DC charging piles, ensuring the efficiency and stability of power distribution.

[0026] In this embodiment: On the outer side of the housing 1, a program download port 13, a communication transfer interface 14, and a power supply interface 15 are fixedly connected. The output pins of the program download port 13 and the power supply interface 15 are electrically connected to the distribution board controller 9 respectively. The distribution board controller 9 is electrically connected to the charging pile through the communication transfer interface 14.

[0027] The program download port 13 is used to download the program to the distribution board controller 9. The power interface 15 is connected to the power input port of the distribution board controller 9. The power interface 15 can provide working power for the distribution board controller 9, the first power distribution board 7, and the second power distribution board 8. The communication transfer interface 14 is a CAN or RS485 communication link. In this way, the distribution board controller 9 can communicate with the controller of the charging pile through the communication transfer interface 14.

[0028] In this embodiment: A pair of dust covers 17 are arranged on the outer side of the housing 1.

[0029] The dust cover 17 is made of high-hardness plastic. The high-hardness plastic has the characteristics of high hardness and light weight. The dust cover 17 is closed and covers the outer side of the housing 1. In this way, the dust cover 17 can block the ventilation part of the fan installation panel to a certain extent, so as to reduce the dust entering the housing 1.

[0030] In this embodiment: Thermal lifting structures 18 are arranged on the top and bottom of the housing 1. The thermal lifting structure 18 includes a liquid storage box 181, the liquid storage box 181 is fixedly connected to the housing 1, a thermal expansion liquid 182 is stored in the liquid storage box 181, a piston plate 183 is slidably connected in the liquid storage box 181, and a lifting rod 184 is fixedly connected to the piston plate 183.

[0031] The liquid storage box 181 can be made of copper material. The copper material has excellent heat conduction characteristics. The thermal expansion liquid 182 is a mercury medium. The mercury can expand when absorbing heat. The expanded mercury can move in the liquid storage box 181 through the piston plate 183. The moving piston plate 183 can drive the lifting rod 184 to lift. In this application, a pressure relief port is arranged at the top of the liquid storage box 181, so that the piston plate 183 can move stably in the positively pressurized liquid storage box 181.

[0032] A traction rod 19 is arranged on the thermal lifting structure 18. One end of the lifting rod 184 passes through the liquid storage box 181 and is fixedly connected to the traction rod 19. A guide rod 4 is fixedly connected to the outer side of the housing 1. The traction rod 19 is slidably connected to the guide rod 4.

[0033] At least two groups of guide rods 4 are arranged. When the traction rod 19 lifts, the guide rod 4 can guide the traction rod 19, so as to stabilize the lifting state of the traction rod 19.

[0034] In this embodiment: A first gear transmission assembly 20 is provided on the towing bar 19. The first gear transmission assembly 20 is connected to the dust cover 17. The first gear transmission assembly 20 includes a first support frame 201. The first support frame 201 is fixedly connected to the outside of the housing 1. A first gear 202 is rotatably connected to the first support frame 201. A first rack 203 and a second rack 204 are respectively meshed and connected to the first gear 202. A sliding frame 205 is fixedly connected to the outside of the housing 1. The first rack 203 is fixedly connected to one end of the towing bar 19. The second rack 204 is slidably connected to the sliding frame 205, and one end of the second rack 204 is fixedly connected to the inner wall of the dust cover 17.

[0035] There are two sets of the first gear transmission assemblies 20. When in use, when the thermal expansion liquid 182 absorbs the working heat of the components in the housing 1, the thermal expansion liquid 182 expands and can squeeze the piston plate 183. The piston plate 183 can push the towing bar 19 on the lifting rod 184 to move linearly. One end of the towing bar 19 can drive the first rack 203 to move vertically. The first rack 203 can mesh with the first gear 202 to rotate. Under the action of the sliding frame 205 guiding the second rack 204 to slide, the rotation of the first gear 202 can drive the second rack 204 to perform a linear motion opposite to that of the first rack 203. In this way, the second rack 204 can push the dust cover 17 away from the housing 1 until the position of the dust cover 17 exposes the position of the fan installation panel 2. In this way, the fan installation panel 2 can provide ventilation for the housing 1.

[0036] Similarly, when the thermal expansion liquid 182 absorbs insufficient heat and returns to the original liquid level state, the piston plate 183 can drop to the promotion state. In this way, a pair of dust covers 17 are closed and covered on the outside of the housing 1. In this way, the dust covers 17 can block the fan installation panel 2. In this way, the housing 1 can achieve the effect of dust prevention.

[0037] In this embodiment: A second gear transmission assembly 21 is provided between a pair of dust covers 17. Fixed frames 16 are fixedly connected to both sides of the housing 1. The second gear transmission assembly 21 includes a second support frame 211. The second support frame 211 is fixedly connected to the fixed frame 16. A second gear 212 is rotatably connected to the second support frame 211. A third rack 213 and a fourth rack 214 are respectively meshed and connected to the second gear 212. The third rack 213 is fixedly connected to the outside of one of the dust covers 17. The fourth rack 214 is fixedly connected to the outside of the other dust cover 17.

[0038] The fixing bracket 16 is provided with mounting holes, and the mounting holes can be connected to the inner wall of the charging pile in cooperation with bolts. The number of the second gear transmission assemblies 21 on each traction rod 19 is two groups. When the second gear transmission assemblies 21 are in use, when one of the dust covers 17 moves away from the outer shell 1, the dust cover 17 can drive the third rack 213 to move vertically. The third rack 213 can engage the second gear 212 to rotate. The rotation of the second gear 212 can drive the fourth rack 214 to move in a straight line opposite to that of the third rack 213. In this way, the two dust covers 17 can synchronously move away from each other in a straight line, so as to quickly open the ventilation position of the fan installation panel 2.

[0039] In this embodiment: A conductive flexible connection structure 22 is provided between one of the dust covers 17 and the outer shell 1. The conductive flexible connection structure 22 is electrically connected to the cooling fan 3. The conductive flexible connection structure 22 includes a column 221 fixedly connected to the top of the outer shell 1. A conductive block 222 is fixedly connected to the column 221. An elastic conductive sheet 223 is fixedly connected to the inner wall of one of the dust covers 17. The elastic conductive sheet 223 is in movable contact with the conductive block 222. The conductive block 222 is electrically connected to the cooling fan 3 through a wire. The elastic conductive sheet 223 is externally connected to a power supply through a wire.

[0040] The elastic conductive sheet 223 is an elastic metal conductor. When the dust cover 1 moves away from the outer shell 1, at this time, the elastic conductive sheet 223 can be in sliding contact with the conductive block 222. The contact between the elastic conductive sheet 223 and the conductive block 222 can form a closed switch. In this way, the external power supply can supply power to the cooling fan 3 through the closed elastic conductive sheet 223 and conductive block 222, and the cooling fan 3 can perform heat dissipation work.

[0041] It should be noted that since the top and bottom of the outer shell 1 are respectively provided with thermal lifting structures 18, in order to prevent the thermal expansion liquid 182 at the top from leaking, the connection between the lifting rod 184 and the liquid storage box 181 can be dynamically sealed through a dynamic seal such as a dynamic seal ring. And because the working temperatures of the components in the outer shell 1 are unevenly distributed on the outer shell 1, when the two thermal expansion liquids 182 absorb heat and expand, the rising degrees of the corresponding piston plates 183 will be different. The opening stroke of the dust cover 17 can automatically adopt the piston plate 183 with the maximum rising degree. And because the second gear transmission assembly 21 can drive a pair of dust covers 17 to move relative to each other, in this way, the synchronism and effectiveness of the heat dissipation opening of the dust cover can be ensured.

[0042] In this embodiment: An avoidance groove 10 is formed on one side of the dust cover 17 facing the communication adapter 14.

[0043] Since one side of the outer shell 1 is provided with a program download port 13, a communication transfer interface 14, a power supply interface 15 and a fixing bracket 16, avoidance grooves 10 for avoiding the corresponding program download port 13, communication transfer interface 14, power supply interface 15 and fixing bracket 16 are provided on the opposite surfaces of a pair of dust covers 17, so that the pair of dust covers 17 can fit better when closed.

[0044] In the attached drawings of the disclosed embodiments of the present invention, only the structures related to the disclosed embodiments are involved. For other structures, reference can be made to the general design. Without conflict, the same embodiment and different embodiments of the present invention can be combined with each other; Finally: The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
