Description

Technical Field

[0001] This utility model belongs to the field of electric vehicle charging pile technology, specifically relating to a high heat dissipation electric vehicle charging pile that adopts full matrix charging technology. Background Technology

[0002] With the development of technology and the increasing environmental awareness of people, new energy electric vehicles are gradually being widely accepted and used as a green mode of transportation to reduce environmental pollution. Although new energy electric vehicles are a pollution-free and zero-emission green mode of transportation, their range problem has posed a serious obstacle to their widespread application. To solve the range problem of electric vehicles, charging stations are generally set up to charge electric vehicles.

[0003] Charging piles function similarly to gas pumps at gas stations. They can be fixed to the ground or walls and installed in public buildings, residential parking lots, or charging stations. They can charge various models of electric vehicles according to different voltage levels. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging gun for charging electric vehicles.

[0004] While multi-gun charging piles exist in the current technology, they still have the following problems: each charging gun is equipped with a fixed charging current, and the charging power cannot be flexibly scheduled. It is not convenient to dynamically adjust the power output of each charging module according to the charging situation. In addition, the heat dissipation efficiency of existing charging piles is low. When multiple charging guns are equipped, if there is no good heat dissipation when maintaining high power operation, it may cause damage to the internal structure of the charging pile or even cause a fire, which is not conducive to ensuring the safety of the use of the charging pile.

[0026] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 9 The embodiments are described in detail below.

[0027] This embodiment provides a high-heat-dissipation electric vehicle charging pile using full-matrix charging technology, as shown in the attached figure. Figure 1-9 As shown, the device includes a charging pile body 1 and a main control module 2. The main control module 2 is located at the top inside the charging pile body 1. The main control module 2 is the control unit of the charging pile body 1 and is used to control the overall operation of the charging pile body 1. This is existing known technology and will not be described in detail here. A mounting bracket 22 is fixedly installed on the bottom of the front of the charging pile body 1, and a positive electrode mounting plate 3 is fixedly installed on the bottom of the mounting bracket 22. A matrix copper busbar mechanism is provided on the front of the positive electrode mounting plate 3. The matrix copper busbar mechanism includes a main copper busbar group 5 and a secondary copper busbar group 5. Group 6, the main copper busbar group 5 consists of a first copper busbar 501, a second copper busbar 502, a third copper busbar 503, a fourth copper busbar 504, a fifth copper busbar 505 and a sixth copper busbar 506. The first copper busbar 501, the second copper busbar 502, the third copper busbar 503 and the fourth copper busbar 504 are all arranged vertically and parallel to each other, and their top ends are all electrically connected to the positive terminal of the external circuit through wires. The fifth copper busbar 505 and the sixth copper busbar 506 are respectively fixedly connected to the top ends of the first copper busbar 501 and the fourth copper busbar 504 and are close to each other.

[0028] The auxiliary copper busbar group 6 consists of a first auxiliary copper busbar 601, a second auxiliary copper busbar 602, a third auxiliary copper busbar 603, and a fourth auxiliary copper busbar 604. There are two of each of the following: two first auxiliary copper busbars 601 are fixedly installed on the side of the first copper busbar 501; two second auxiliary copper busbars 602 are fixedly installed on the side of the second copper busbar 502; two third auxiliary copper busbars 603 are fixedly connected to the side of the third copper busbar 503; and two fourth auxiliary copper busbars 604 are fixedly installed on the side of the fourth copper busbar 504.

[0029] A DC contactor group for controlling the on / off state of the matrix copper busbar mechanism is fixedly mounted on the front side of the positive electrode mounting plate 3. The DC contactor group is distributed in various connection parts within the matrix copper busbar mechanism. The DC contactor group includes a first DC contactor 7, a second DC contactor 8, a third DC contactor 9, a fourth DC contactor 10, a fifth DC contactor 11, and a sixth DC contactor 12. One of the first auxiliary copper busbars 601 can be electrically connected to one of the third auxiliary copper busbars 603 through the first DC contactor 7. Another first auxiliary copper busbar 601 can be electrically connected to one of the second auxiliary copper busbars 602 through the second DC contactor 8, and the second auxiliary copper busbar 602 is located away from the second auxiliary copper busbar. One end of DC contactor 8 can be electrically connected to one end of another third auxiliary copper busbar 603 through a third DC contactor 9, and the end of another third auxiliary copper busbar 603 away from the third DC contactor 9 can be electrically connected to one of the fourth auxiliary copper busbars 604 through a fourth DC contactor 10. Another fourth auxiliary copper busbar 604 can be electrically connected to another second auxiliary copper busbar 602 through a fifth DC contactor 11. The fifth copper busbar 505 can be electrically connected to the sixth copper busbar 506 through a sixth DC contactor 12. By controlling each DC contactor, the matrix copper busbar mechanism can be controlled to output different power to different charging guns, which is convenient for dynamically adjusting the charging power of each charging gun.

[0030] The bottom ends of the first copper busbar 501, the second copper busbar 502, the third copper busbar 503, and the fourth copper busbar 504 are all provided with connecting copper busbars 13. The connection points between the first copper busbar 501, the second copper busbar 502, the third copper busbar 503, and the fourth copper busbar 504 and their corresponding connecting copper busbars 13 are all provided with main DC contactors 14. The main DC contactors 14 are used to control the power supply to and from each charging gun. The first DC contactor 7, the second DC contactor 8, the third DC contactor 9, the fourth DC contactor 10, the fifth DC contactor 11, the sixth DC contactor 12, and the main DC contactor 14 are also connected to the main DC contactor 13. The DC contactors 14 are all fixedly installed on the side of the positive pole mounting plate 3 and are all electrically connected to the main control module 2. The main control module 2 can control the switching of the corresponding DC contactors, which can control the on / off of the corresponding copper busbars. The first copper busbar 501, the second copper busbar 502, the third copper busbar 503 and the fourth copper busbar 504 can be electrically connected to the corresponding connecting copper busbars 13 through the four main DC contactors 14 respectively. The bottom of the four connecting copper busbars 13 on the positive pole mounting plate 3 is fixedly installed with fuses 15. The bottom of the four fuses 15 is electrically connected to the positive pole of the four charging guns through wires.

[0031] A negative electrode mounting plate 4 is arranged parallel to the positive electrode mounting plate 3 at its rear. The front of the negative electrode mounting plate 4 has the same matrix copper busbar mechanism and DC contactor group as the front of the positive electrode mounting plate 3. The matrix copper busbar mechanism and DC contactor group on the negative electrode mounting plate 4 operate in the same manner as those on the positive electrode mounting plate 3. A shunt is fixedly connected to the bottom of the matrix copper busbar mechanism on the negative electrode mounting plate 4 via a connecting copper busbar 13. The bottom end of the shunt is electrically connected to the negative terminals of the four charging guns via wires. The matrix copper busbar mechanism on the front of the negative electrode mounting plate 4... The bottom of the charging structure is electrically connected to the negative terminal of the external circuit. The positive terminal mounting plate 3 and the negative terminal mounting plate 4 are both vertically fixed inside the bottom of the charging pile body 1. The sides of the positive terminal mounting plate 3 and the negative terminal mounting plate 4 are provided with ventilation holes 29 to facilitate ventilation and heat dissipation. The ventilation holes 29 can promote air flow in the front area of ​​the positive terminal mounting plate 3 and the negative terminal mounting plate 4, promote ventilation and heat dissipation in this area, and facilitate the movable heat dissipation mechanism and the adjustable heat dissipation mechanism to blow air into the area, making the air circulation efficiency of this area higher and more conducive to heat dissipation.

[0032] The mounting bracket 22 has an internal movable cooling mechanism for blowing air to cool the matrix copper busbar mechanism on the main control module 2 and the negative mounting plate 4. This movable cooling mechanism includes an upper air blade 23, a lower air blade 24, a geared motor 25, a transmission gear 26, a splitter pipe 27, and an air pump 28. The upper air blade 23 and the lower air blade 24 are rotatably connected to each other and rotatably connected inside the mounting bracket 22. One end of the lower air blade 24 is connected to the output end of the geared motor 25 via a spline connection, and the geared motor 25 is fixedly mounted on the mounting bracket 22. The air outlet directions of the upper air blade 23 and the lower air blade 24 are respectively... Both the upper and lower sides of the wind blades 23 and 24, facing upwards and downwards respectively, are connected to the diversion pipe 27. A transmission gear 26 is fixedly connected to each side of the upper and lower wind blades 23 and 24, with the upper and lower gears 26 meshing with each other. The air outlet of the air pump 28 is connected to the air inlet of the diversion pipe 27, and the air pump 28 is fixedly installed inside the charging pile body 1. When the reduction motor 25 drives the lower wind blade 24 to swing, it can drive the upper wind blade 23 to swing synchronously in the opposite direction through the transmission gear 26, thus enabling the upper wind blade 23 and the lower wind blade 24 to swing synchronously relative to each other. Pump 28 blows air into the upper air blade 23 and lower air blade 24 through the diversion pipe 27, thus forming an air curtain with the same width as the outlet of the upper air blade 23 and lower air blade 24. This allows for airflow cooling of the main control module 2 above and the matrix copper busbar structure below. The geared motor 25 drives the lower air blade 24 and upper air blade 23 to swing left and right. Initially, both the upper air blade 23 and lower air blade 24 are vertical, and their left and right swing range is within 45 degrees, thus providing sufficient airflow cooling to the front area of ​​the charging pile body 1. The lower air blade 24 is connected to the negative electrode mounting plate 4. Corresponding to the rectangular copper busbar mechanism, when the air blade 24 swings towards the side closer to the positive electrode mounting plate 3, the air it blows can enter the area on the front of the positive electrode mounting plate 3 through the ventilation holes 29 on the positive electrode mounting plate 3, thereby ventilating and dissipating heat for the matrix copper busbar mechanism on the positive electrode mounting plate 3; when the air blade 24 swings towards the side of the negative electrode mounting plate 4, it can fully blow air and dissipate heat for the matrix copper busbar mechanism on the negative electrode mounting plate 4, and the blown air will also pass through the ventilation holes 29 on the negative electrode mounting plate 4 and enter the rear area, thereby promoting the overall air circulation inside the charging pile body 1, which can greatly improve the heat dissipation efficiency.

[0033] Both sides of the charging pile body 1 are hinged with side protective doors 16, and one of the side protective doors 16 has an adjustable heat dissipation mechanism on its inner side that can simultaneously dissipate heat from the main control module 2 and the matrix copper busbar mechanism. The adjustable heat dissipation mechanism includes a fixed cooling fan 18, a movable cooling fan 19, and an electric push rod 20. There are several fixed cooling fans 18, which are vertically fixed on the inner side of the side protective door 16 and correspond to the main control module 2, so as to fully dissipate heat from the main control module 2. The movable cooling fan 19 is hinged to the inner side of the side protective door 16 and corresponds vertically to the fixed cooling fan 18. The fixed rod of the electric push rod 20 is hinged to the inner side of the side protective door 16, and the end of the movable rod is hinged to the middle of the side of the movable cooling fan 19. When the movable rod of the electric push rod 20 extends, it can push the movable cooling fan 19 to a state that corresponds vertically to the fixed cooling fan 18. At this time, the movable cooling fan 19... The charging pile is parallel to the side protective door 16. When the charging pile charges multiple vehicles simultaneously, the main control module 2 detects an increase in operating power, indicating that it is operating at high efficiency and will generate more heat. At this time, the main control module 2 controls the electric push rod 20 to retract inward, which allows the movable cooling fan 19 to rotate along the hinge, creating an angle between the movable cooling fan 19 and the side protective door 16. This aligns the movable cooling fan 19 with the back of the negative electrode mounting plate 4, allowing the movable cooling fan 19 to blow air onto the negative electrode mounting plate 4 for cooling. The cold air will also pass through the ventilation holes on the sides of the negative electrode mounting plate 4 and the positive electrode mounting plate 3 to cool the matrix copper busbar mechanism and DC contactor group on the negative electrode mounting plate 4 and the positive electrode mounting plate 3. This provides directional airflow cooling for the matrix copper busbar mechanism and the DC contactor group, greatly improving the heat dissipation efficiency of this part and effectively preventing damage to the charging pile due to excessive temperature.

[0034] The inner side of the other side protective door 16 is bonded with dustproof cotton 17. Both side protective doors 16 have heat dissipation holes 21 for ventilation and heat dissipation. The adjustable heat dissipation mechanism and the dustproof cotton 17 are corresponding to their respective heat dissipation holes 21. The heat dissipation holes 21 can ensure that heat is dissipated quickly. At the same time, the dustproof cotton 17 can ensure normal ventilation of the heat dissipation holes 21 and prevent external dust particles from entering the charging pile, thus playing a good protective role for the inside of the charging pile.

[0035] The fixed cooling fan 18, the movable cooling fan 19, the electric push rod 20, the geared motor 25, and the air pump 28 are all electrically connected to the main control module 2.

[0036] In summary, the high heat dissipation electric vehicle charging pile using full-matrix charging technology can be used in the following ways:

[0037] 1. The charging station can be controlled to switch between different charging modes via the main control module 2:

[0038] Mode 1: Single gun at full power

[0039] (1) Full power of the charging gun corresponding to the first copper busbar 501: When the charging gun is charging at full power, the main DC contactor 14 corresponding to the first copper busbar 501 connects the first copper busbar 501 to the corresponding connecting copper busbar 13. The second copper busbar 502 is connected to the first copper busbar 501 through the second DC contactor 8. The third copper busbar 503 is connected to the first copper busbar 501 through the third DC contactor 9. The fourth copper busbar 504 is connected to the first copper busbar 501 through the fourth DC contactor 10. The other DC contactors are in the open state.

[0040] (2) Full power of the charging gun corresponding to the second copper busbar 502: When the charging gun is charging at full power, the first copper busbar 501 is electrically connected to the second copper busbar 502 through the second DC contactor 8, the main DC contactor 14 corresponding to the second copper busbar 502 is electrically connected to the corresponding connecting copper busbar 13, the third copper busbar 503 is electrically connected to the second copper busbar 502 through the third DC contactor 9, the fourth copper busbar 504 is electrically connected to the second copper busbar 502 through the fourth DC contactor 10, and the other DC contactors are in the open state;

[0041] (3) Full power of the charging gun corresponding to the third copper busbar 503: When the charging gun is charging at full power, the first copper busbar 501 is electrically connected to the third copper busbar 503 through the first DC contactor 7, the second copper busbar 502 is electrically connected to the third copper busbar 503 through the third DC contactor 9, the main DC contactor 14 corresponding to the third copper busbar 503 connects the third copper busbar 503 to the corresponding connecting copper busbar 13, the fourth copper busbar 504 is electrically connected to the third copper busbar 503 through the fourth DC contactor 10, and the other DC contactors are in the open state;

[0042] (4) Full power of the charging gun corresponding to the fourth copper busbar 504: When the charging gun is charging at full power, the fifth copper busbar 505 on the first copper busbar 501 is electrically connected to the sixth copper busbar 506 on the fourth copper busbar 504 through the sixth DC contactor 12, the second copper busbar 502 is electrically connected to the fourth copper busbar 504 through the fifth DC contactor 11, the third copper busbar 503 is electrically connected to the fourth copper busbar 504 through the fourth DC contactor 10, the main DC contactor 14 corresponding to the fourth copper busbar 504 connects the fourth copper busbar 504 to the corresponding connecting copper busbar 13, and the other DC contactors are in the open state.

[0043] Mode 2: Charging with two charging guns simultaneously

[0044] When the two charging guns corresponding to the first copper busbar 501 and the second copper busbar 502 are charging simultaneously, the first copper busbar 501 outputs to the corresponding charging gun through its corresponding main DC contactor 14, and the third copper busbar 503 is electrically connected to the first copper busbar 501 through the first DC contactor 7; the second copper busbar 502 outputs to the corresponding charging gun through its corresponding main DC contactor 14, and the fourth copper busbar 504 is electrically connected to the second copper busbar 502 through the fifth DC contactor 11, while the other DC contactors are in an open state; the charging power of each charging gun is half of the total power of the charging pile. Similarly, when any two charging guns are charging simultaneously, the other two idle charging lines are electrically connected to the copper busbars corresponding to the two charging guns respectively through the corresponding DC contactors.

[0045] Mode 3: Charging with three charging guns simultaneously

[0046] When the three charging guns corresponding to the first copper busbar 501, the second copper busbar 502, and the third copper busbar 503 are charging simultaneously, each of the three copper busbars is electrically connected to its corresponding connecting copper busbar 13 via its corresponding main DC contactor 14, allowing electrical energy to be output to the three charging guns. If the charging gun corresponding to the first copper busbar 501 requires fast charging mode, the fourth copper busbar 504 is electrically connected to the first copper busbar 501 via the sixth DC contactor 12. In this case, the charging power of the charging gun corresponding to the first copper busbar 501 is half of the total charging power, and the charging power of the charging guns corresponding to the second and third copper busbars 502 and 503 is one-quarter of the total charging power. Similarly, any three charging guns can be controlled to charge via DC contactors. The copper busbar corresponding to an idle charging gun can be electrically connected to the copper busbar of the charging gun requiring fast charging via its corresponding DC contactor, achieving the effect of simultaneous charging of all three guns.

[0047] 2. When the charging pile charges multiple vehicles simultaneously, the main control module 2 detects an increase in operating power and controls the movable rod of the electric push rod 20 to retract inward, causing the movable cooling fan 19 to rotate along the hinge. The movable cooling fan 19 aligns with the back of the negative electrode mounting plate 4, and the movable cooling fan 19 blows air onto the negative electrode mounting plate 4 for cooling. The cold air passes through the ventilation holes on the sides of the negative electrode mounting plate 4 and the positive electrode mounting plate 3 in sequence to cool the matrix copper busbar mechanism and DC contactor group on the negative electrode mounting plate 4 and the positive electrode mounting plate 3. The directional blowing of air onto the matrix copper busbar mechanism and the DC contactor group greatly improves the heat dissipation efficiency of this part and effectively prevents the charging pile from being damaged due to excessive temperature.

[0048] 3. The air pump 28 blows air into the upper air blade 23 and lower air blade 24 through the diversion pipe 27, so that an air curtain with the same width as the outlet of the upper air blade 23 and lower air blade 24 is formed. The air blows air to cool the main control module 2 above and the matrix copper busbar structure below. The geared motor 25 drives the lower air blade 24 and the upper air blade 23 to swing left and right. The upper air blade 23 and the lower air blade 24 are initially in a vertical state. The range of their left and right swing is within 45 degrees, which fully blows air to cool the front area inside the charging pile body 1.

[0049] 4. The downwind blade 24 corresponds to the rectangular copper busbar mechanism on the negative electrode mounting plate 4. When the downwind blade 24 swings towards the side closer to the positive electrode mounting plate 3, the air it blows out enters the area on the front of the positive electrode mounting plate 3 through the ventilation hole 29 on the positive electrode mounting plate 3, ventilating and dissipating heat for the matrix copper busbar mechanism on the positive electrode mounting plate 3. When the downwind blade 24 swings towards the side of the negative electrode mounting plate 4, it fully blows air to dissipate heat for the matrix copper busbar mechanism on the negative electrode mounting plate 4, and the air blown out also passes through the ventilation hole 29 on the negative electrode mounting plate 4 and enters the rear area, thereby promoting the overall air circulation inside the charging pile body 1 and greatly improving the heat dissipation efficiency.

[0050] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
