[0029] Embodiment: A copper busbar for new energy vehicles with an automatic sealing structure, see Figure 1-Figure 7 As shown, a copper busbar is included, and the copper busbar includes a copper plate 101 and an insulating sleeve 102; the outer surface of the copper plate 101 is wrapped with an insulating sleeve 102, and the insulating sleeve 102 outside the copper plate 101 is mainly used to provide electrical insulation and physical protection. The length of the insulating sleeve 102 is shorter than the copper plate 101, so that both ends of the copper plate 101 are in a bare state. By installing bolts 103 at both ends of the copper plate 101, the copper plate 101 can be fixed on the electrical appliance by using the bolts 103;

[0030] It also includes a sliding block Ⅰ3, an insulating sealing frame 4, a sliding plate 5, a silica gel block 6, a vent pipe 7, a guiding mechanism, a moving mechanism and a drying mechanism; a guiding mechanism is provided on the insulating sleeve 102; two sliding blocks Ⅰ3 are slidably connected to the guiding mechanism; the sliding block Ⅰ3 is connected to an insulating sealing frame 4 for sealing the port of the copper plate 101. When the port of the copper plate 101 is installed on the electrical appliance, the port of the copper plate 101 is covered by the insulating sealing frame 4, so that the port of the copper plate 101 can be placed in a closed space, thereby preventing dust from accumulating on the port of the copper plate 101 to form dust accumulation, and also preventing moisture in the outside air from oxidizing the port of the copper plate 101; a sliding plate 5 is slidably provided in the insulating sealing frame 4, and a silica gel block 6 is connected to the side of the sliding plate 5 facing the copper plate 101; the insulating sealing frame 4 is provided with a moving mechanism, which is used to control the silicone block 6 to adhere to the outer surface of the copper plate 101 port, so that when the insulating sealing frame 4 covers the copper plate 101 port, the silicone block 6 can simultaneously squeeze out the moisture around the copper plate 101 port from the insulating sealing frame 4, thereby preventing the residual moisture in the insulating sealing frame 4 from oxidizing the copper plate 101 port; a ventilation pipe 7 is provided between the sliding plate 5 and the silicone block 6. In order to prevent the silicone block 6 from adhering to the outer surface of the copper plate 101 port and affecting the heat dissipation, when the moving mechanism controls the silicone block 6 to stay away from the outer surface of the copper plate 101 port, air needs to be introduced through the ventilation pipe 7 to stabilize the air pressure around the copper plate 101 port; a drying mechanism for drying the air is provided in the ventilation pipe 7 to prevent the air introduced by the ventilation pipe 7 from containing moisture.

[0031] See also Figure 3 As shown, the guide mechanism includes an insulating shell 201, a guide rail frame 202 and a screw 203; insulating shells 201 are slidably arranged at both ends of the insulating sleeve 102; the outer side of the insulating shell 201 is connected to a guide rail frame 202 for sliding the sliding block Ⅰ3, and the sliding block Ⅰ3 is slidably connected to the guide rail frame 202; a screw 203 threadedly connected to the sliding block Ⅰ3 is rotatably arranged on the guide rail frame 202, and the sliding block Ⅰ3 can slide on the guide rail frame 202 by twisting the screw 203 to rotate.

[0032] See also Figure 4-Figure 6As shown, the moving mechanism includes a magnetic plate Ⅰ801, a sliding member, a magnetic plate Ⅱ802 and an iron plate 10; a magnetic plate Ⅰ801 is arranged in the middle of the sliding plate 5; a sliding member is arranged on the outside of the insulating closed frame 4, and the sliding member includes a strip guide rail 901 and a sliding block Ⅱ902, and the strip guide rail 901 is symmetrically arranged on the side of the insulating closed frame 4 away from the copper plate 101, and a sliding block Ⅱ902 is slidably arranged between the strip guide rails 901 on the insulating closed frame 4; the sliding block Ⅱ902 is connected to the magnetic plate Ⅱ802, and the magnetic plate Ⅱ802 is connected to the sliding block Ⅱ902. The force plate II 802 is in contact with the outer wall of the insulating closed frame 4, and the sides of the magnetic plate I 801 and the magnetic plate II 802 facing each other are of the same pole. Through the repulsion of the same poles of the magnetic plate I 801 and the magnetic plate II 802, the sliding plate 5 and the silicone block 6 can slide in the insulating closed frame 4 toward the side away from the magnetic plate II 802; the sliding block II 902 is connected to the iron plate 10, and through the magnetic attraction between the iron plate 10 and the magnetic plate I 801, the sliding plate 5 and the silicone block 6 can slide in the insulating closed frame 4 toward the side close to the iron plate 10.

[0033] See also Figure 7 As shown, the drying mechanism includes a shielding cloth 1101 and a desiccant 1102; shielding cloths 1101 are provided at both ends of the ventilation pipe 7; a desiccant 1102 for drying air is placed in the ventilation pipe 7, and the shielding cloth 1101 is used to block the desiccant 1102 in the ventilation pipe 7, and the shielding cloth 1101 does not affect the passage of air through the ventilation pipe 7.

[0034] In the initial state, the magnetic plate II 802 on the sliding block II 902 is aligned with the magnetic plate I 801 in the middle of the sliding plate 5, so that the magnetic plate I 801 and the magnetic plate II 802 can repel each other through the same polarity to squeeze the sliding plate 5 and the silicone block 6 in the insulating closed frame 4 to be far away from the sliding block II 902 (such as Figure 4 , Figure 5 and Figure 6 shown);

[0035] When the copper busbar of the new energy vehicle needs to be installed, first pull the insulating casing 201 to slide on the insulating casing 102, so that the guide rail frame 202, the sliding block I3 and the insulating closing frame 4 move with the insulating casing 201, until the insulating closing frame 4 is away from the port of the copper plate 101, so that the insulating closing frame 4 does not affect the operator's installation of the bolt 103 on the port of the copper plate 101, and then the operator installs the bolt 103 on the port of the copper plate 101, and the operator uses the bolt 103 to fix the port of the copper plate 101 on the electrical appliance, and then pull the insulating casing 201 to slide and reset on the insulating casing 102, so that the guide rail frame 202, the sliding block I3 and the insulating closing frame 4 move and reset with the insulating casing 201, and then twist the screw 203 to rotate, so that the screw 203 drives the sliding block I3 and the insulating closing frame 4 to move Move to the side close to the electrical appliance, and move the sliding plate 5 and the silicone block 6 in the insulating sealing frame 4 to the side close to the bolt 103. When the silicone block 6 contacts the bolt 103 and the copper plate 101 port, the bolt 103 and the copper plate 101 port will squeeze the silicone block 6 to deform, and make the silicone block 6 fit to the outer surface of the bolt 103 and the copper plate 101 port, so that the silicone block 6 squeezes the moisture on the outer surface of the copper plate 101 port to the outside of the insulating sealing frame 4, thereby removing the moisture in the insulating sealing frame 4. When the insulating sealing frame 4 contacts the outer surface of the electrical appliance, the insulating sealing frame 4 can seal the copper plate 101 port, so that the copper plate 101 port is in a closed space, so that dust can be prevented from accumulating on the copper plate 101 port to form dust accumulation, and moisture in the outside air can also be prevented from oxidizing the copper plate 101 port;After the copper plate 101 port is completely closed, the sliding block II 902 is pulled to move, so that the magnetic plate II 802 on the sliding block II 902 is no longer aligned with the magnetic plate I 801, and the iron plate 10 on the sliding block II 902 is aligned with the magnetic plate I 801. In this way, the sliding plate 5 and the silicone block 6 can slide to the side close to the iron plate 10 in the insulating sealing frame 4 through the magnetic attraction of the iron plate 10 and the magnetic plate I 801, so that the silicone block 6 is separated from the bolt 103 and the copper plate 101 port until the sliding plate 5 and the silicone block 6 are in a position close to the sliding block II 902 in the insulating sealing frame 4. During this period, when the sliding plate 5 and the silicone block 6 slide to the side close to the iron plate 10 in the insulating sealing frame 4, the sliding plate 5 will squeeze the air between itself and the insulating sealing frame 4, so that the sliding plate 5 The air between the insulating sealing frame 4 enters the vicinity of the port of the copper plate 101 from the vent pipe 7, thereby stabilizing the air pressure around the port of the copper plate 101, thereby ensuring that the magnetic attraction between the iron plate 10 and the magnetic plate Ⅰ801 can completely drive the silicone block 6 away from the bolt 103 and the port of the copper plate 101, and when the air passes through the vent pipe 7, the desiccant 1102 in the vent pipe 7 will dry the air, thereby removing moisture in the air, thereby preventing the moisture in the air from oxidizing the port of the copper plate 101, when the silicone block 6 is separated from the bolt 103 and the port of the copper plate 101, the silicone block 6 will return to its original state due to its own material characteristics, and by separating the silicone block 6 from the bolt 103 and the port of the copper plate 101, it can prevent the silicone block 6 from affecting the appearance of the port of the copper plate 101 and the bolt 103 for heat dissipation;

[0036] When it is necessary to remove the copper busbar of the new energy vehicle, twist the screw 203 to reverse it, so that the screw 203 drives the sliding block Ⅰ3 and the insulating closing frame 4 to move to the side away from the electrical appliance, and the sliding plate 5 and the silicone block 6 in the insulating closing frame 4 move to the side away from the bolt 103, so that the insulating closing frame 4 is separated from the outer surface of the electrical appliance, so that the insulating closing frame 4 releases the sealing of the bolt 103 and the copper plate 101 port, and then pull the insulating shell 201 to slide on the insulating sleeve 102 again, so that the guide rail frame 202, the sliding block Ⅰ3 and the insulating closing frame 4 follow the insulating shell 201 to move until the insulating closing frame 4 is away from the port of the copper plate 101, and then the operator removes the bolt 103 on the port of the copper plate 101 to loosen the copper plate 101 from the electrical appliance, and then pulls the insulating shell 201 to slide and reset on the insulating sleeve 102 again, so that the guide rail frame 202, the sliding block Ⅰ3 and the insulating closing frame 4 follow the insulating shell 201 is moved and reset, and finally the sliding block II 902 is pulled to move and reset, so that the iron plate 10 on the sliding block II 902 is no longer aligned with the magnetic plate I 801, and the magnetic plate II 802 on the sliding block II 902 is aligned with the magnetic plate I 801. In this way, the sliding plate 5 and the silicone block 6 can slide to the side away from the magnetic plate II 802 in the insulating closed frame 4 through the same-pole repulsion between the magnetic plate I 801 and the magnetic plate II 802, until the sliding plate 5 and the silicone block 6 are in a position away from the sliding block II 902 in the insulating closed frame 4. During this period, when the sliding plate 5 and the silicone block 6 slide to the side away from the magnetic plate II 802 in the insulating closed frame 4, the outside air will enter the space between the sliding plate 5 and the insulating closed frame 4 from the ventilation pipe 7, thereby stabilizing the air pressure between the sliding plate 5 and the insulating closed frame 4, thereby ensuring that the same-pole repulsion between the magnetic plate I 801 and the magnetic plate II 802 can completely drive the sliding plate 5 and the silicone block 6 to move and reset.

[0037] See also Figure 8 As shown, a sealing gasket 12 is also included; a sealing gasket 12 is provided on one side of the insulating sealing frame 4 close to the copper plate 101, and the sealing gasket 12 is in contact with the outer surface of the electrical appliance, and the sealing gasket 12 can be used to seal the inside of the insulating sealing frame 4, thereby improving the sealing performance of the insulating sealing frame 4.

[0038] See also Figure 8 As shown, it also includes a heat dissipation fin 13; the outer side of the insulating closed frame 4 is provided with a heat dissipation fin 13 for heat dissipation. After the insulating closed frame 4 closes the port of the copper plate 101, when the heat dissipated from the port of the copper plate 101 is transferred to the outer surface of the insulating closed frame 4, the heat dissipation of the insulating closed frame 4 can be accelerated by using the heat dissipation fin 13, thereby preventing a series of problems caused by untimely heat dissipation on the outer surface of the insulating closed frame 4.
