Description

Technical Field

[0001] This utility model relates to the field of charging equipment technology, specifically to a European standard charging dock integrated junction box. Background Technology

[0002] One issue with electric buses is their short driving range. Currently, the average driving range of electric buses in China is around 200 kilometers. Secondly, the charging speed is too slow. At present, most electric buses require at least one hour to charge from 0% to 80%, and slow charging takes 6-7 hours, resulting in poor usability.

[0003] Therefore, the research objective of this utility model is to design an integrated European standard charging dock junction box that can achieve high current and fast power-on, thereby improving charging efficiency. Utility Model Content

[0004] To address the technical problems existing in the prior art, this utility model provides an integrated junction box for a European standard charging dock, which effectively solves the technical problems existing in the prior art.

[0005] The technical solution of this utility model is: A European standard charging dock integrated distribution box, comprising: Box body; The European standard charging dock is detachably fixed to the outer rear end of the box. An even number of glands are installed on the outer front end of the housing and form the same number of positive and negative output terminals; A low-voltage communication component is installed on the outer front end of the box and connected to the PE grounding wire and low-voltage wire on the European standard charging dock; Two sets of connection components are set inside the box to connect the positive and negative terminals of the European standard charging base to the output positive and output negative terminals respectively. The connection components include several output copper busbars connected in parallel to the positive or negative terminals of the European standard charging base. The output copper busbars and the glands are connected one-to-one. Temperature measuring mechanism: Each output copper busbar is equipped with a corresponding temperature measuring mechanism. The temperature of the output copper busbar on the same connection component is detected by the temperature measuring mechanism and the temperature difference is compared.

[0006] The box is equipped with a vent valve for balancing the air pressure inside and outside the box.

[0007] The connection assembly includes two parallel output copper busbars, one of which is straight and the other is Z-shaped. The two output copper busbars are fitted together and fixedly connected by a first insulator. Either output copper busbar is fixed to the housing by a second insulator.

[0008] The cross-sectional area of ​​both output copper busbars is greater than 200 mm². 2 This allows the output copper busbar to carry a continuous current greater than 500A at 40°C.

[0009] The positive and negative terminals of the European standard charging dock are respectively connected to the connection component through corresponding input copper busbars, and are also connected to any one of the output copper busbars in the connection component.

[0010] The corresponding OT terminals are fixed to the output copper busbars by bolts, and the OT terminals are connected to the glands one by one by the corresponding wires.

[0011] The temperature measuring mechanism consists of a surface-mount NTC connected to a PCB board, and temperature is detected through the surface-mount NTC.

[0012] The electronic lock on the European standard charging dock is connected to any one of the output copper busbars.

[0013] An inspection port is provided on the side of the box body where the second insulator is not fixed, and a corresponding cover plate is fixedly and sealed by a sealing ring and bolts.

[0014] Advantages of this utility model: 1) This utility model integrates a European standard charging base and a national standard gland and low-voltage communication component into a compact box through the cooperation of a connecting component and a temperature measuring mechanism. This facilitates the connection between national and European standards to achieve high-current fast charging. Furthermore, the connecting component is set as two parallel-connected output copper busbars. The minimum allowable continuous current of both output copper busbars is greater than 500A. This ensures that even if one side fails to charge, the single branch copper busbar design can still meet the 500A overcurrent requirement in a short time. This not only reduces the size and installation complexity of the integrated junction box, but also ensures a stable connection under high current and avoids the energy loss of traditional distributed designs.

[0015] 2) For the parallel dual copper busbar configuration, even if one side fails, a single busbar can still meet the 500A overcurrent requirement. However, if only one side is subjected to overcurrent, the temperature of the copper busbar will increase, and its lifespan will be greatly reduced. Therefore, this utility model further sets up a corresponding temperature measuring mechanism on each output copper busbar to detect the temperature of each output copper busbar during use. When a single busbar fails, the temperature difference between the failed and overcurrent output copper busbars is large, which can then be fed back to the user. This facilitates timely replacement of the integrated junction box for charging, ensuring continuous charging, and timely repair of damaged integrated junction boxes, thereby improving the practical effect of this utility model.

[0016] 3) To ensure the practicality and safety of the integrated junction box, the box is sealed. However, this will cause a pressure difference between the inside and outside of the box, which may lead to overheating and danger if it is not kept for a long time. Therefore, this utility model further adds a corresponding vent valve to the box to balance the pressure inside and outside of the box and further improve the practicality of the integrated junction box.

[0017] 4) The two output copper busbars are respectively designed in a straight plate shape and a Z-shaped shape, and are fixedly connected by insulators, achieving parallel connection of the two output copper busbars while ensuring ease of installation; furthermore, the cross-sectional area of ​​the output copper busbars is set to be greater than 200mm². 2 This ensures that each output copper busbar can carry a continuous current greater than 500A at 40°C, enabling fast charging from 0 to 80% capacity, reducing the time from 1 hour to within 30 minutes, effectively improving efficiency.

[0022] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings: refer to Figure 1-3 A European standard charging dock integrated distribution box, comprising: Box 1; The European standard charging dock 2 is detachably fixed to the outer rear end of the box body 1; An even number of gland heads 3 are installed on the outer front end of the housing 1 to form the same number of positive and negative output terminals; The low-voltage communication component 4 is installed on the outer front end of the box 1 and is connected to the PE grounding wire and the low-voltage wire on the European standard charging base 2. Two sets of connection components are set inside the housing 1 to connect the positive and negative terminals of the European standard charging base 2 to the output positive and output negative terminals of the gland 3, respectively. The connection components include several output copper busbars 5 connected in parallel to the positive or negative terminals of the European standard charging base 2. The output copper busbars 5 and the gland 3 are connected one-to-one. Temperature measuring mechanism 6: Each of the output copper busbars 5 is equipped with a corresponding temperature measuring mechanism 6. The temperature of the output copper busbars 5 on the same connection component is detected by the temperature measuring mechanism 6 and the temperature difference is compared.

[0023] This utility model integrates a European standard charging base 2, a Chinese standard gland connector 3, and a low-voltage communication component into a compact small box 1 through a connecting component and a temperature measuring mechanism 6. This facilitates fast charging for both Chinese and European standards. Furthermore, the connecting component is configured with two parallel-connected output copper busbars 5, each with a minimum allowable continuous current greater than 500A. This ensures that even in the event of a single-sided charging failure, the single-branch copper busbar design can still meet the 500A overcurrent requirement for a short period of time. This not only reduces the size and installation complexity of the integrated junction box but also ensures a stable connection under high current, avoiding the energy loss of traditional distributed designs.

[0024] The temperature measuring mechanism 6 is composed of a surface-mount NTC connected to a PCB board, and temperature is detected through the surface-mount NTC.

[0025] For parallel dual copper busbars, even if one side fails, a single busbar can still meet the 500A overcurrent requirement. However, if only one side is subjected to overcurrent, the temperature of that copper busbar will increase, and its lifespan will be greatly reduced. Therefore, this utility model further sets up a corresponding temperature measuring mechanism 6 on each output copper busbar 5 to detect the temperature of each output copper busbar 5 during use. When a single busbar fails, the temperature difference between the failed and overcurrent output copper busbar 5 is large, which can then be fed back to the user. This facilitates timely replacement of the integrated junction box for charging, ensuring continuous charging, and timely repair of damaged integrated junction boxes, thereby improving the practical effect of this utility model.

[0026] The box 1 is equipped with a vent valve 7 for balancing the air pressure inside and outside the box 1.

[0027] To ensure the practicality and safety of the integrated junction box, the box body 1 is sealed. However, this will cause a pressure difference between the inside and outside of the box body 1, which may lead to overheating and danger if it is not kept for a long time. Therefore, this utility model further adds a corresponding vent valve 7 to the box body 1 to balance the pressure inside and outside of the box body 1 and further improve the practicality of the integrated junction box.

[0028] The connection assembly includes two parallel output copper busbars 5, one of which is straight and the other is Z-shaped. The two output copper busbars 5 are fitted together and fixedly connected by a first insulator 10. Either output copper busbar 5 is fixed to the housing 1 by a second insulator 11.

[0029] For example, the straight-plate output copper busbar 5 has a thickness of 5mm, a width of 45mm, and a cross-sectional area of ​​225mm². 2 The Z-shaped output copper busbar 5 has a thickness of 4mm, a width of 55mm, and a cross-sectional area of ​​220mm². 2 The cross-sectional area of ​​both output copper busbars 5 is greater than 200 mm². 2 This allows the output copper busbar 5 to carry a continuous current greater than 500A at a current carrying capacity of 40°C.

[0030] The two output copper busbars 5 are respectively designed in a straight plate shape and a Z-shaped shape, and are fixedly connected by insulators, achieving parallel connection of the two output copper busbars 5 while ensuring convenient installation; furthermore, the cross-sectional area of ​​each output copper busbar 5 is set to be greater than 200mm². 2 This ensures that each output copper busbar 5 can carry a continuous current greater than 500A at 40°C, enabling fast charging from 0 to 80% capacity, reducing the time from 1 hour to within 30 minutes, effectively improving efficiency.

[0031] The positive and negative terminals of the European standard charging base 2 are respectively connected to the connection component through corresponding input copper busbars 8, and are also connected to any one of the output copper busbars 5 in the connection component.

[0032] The corresponding OT terminals 12 are fixed to the output copper busbar 5 by bolts, and the OT terminals 12 are connected to the gland 3 one by one by the corresponding wires.

[0033] The electronic lock 9 on the European standard charging dock 2 is connected to any one of the output copper busbars 5.

[0034] The side of the box 1 where the second insulator 11 is not fixed is provided with an inspection port, and a corresponding cover plate 13 is fixedly and sealed by a sealing ring and bolts.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
