Description

Technical Field

[0001] The utility model belongs to the technical field of new energy charging seats, and specifically relates to a high-voltage charging seat. Background Art

[0002] New energy vehicle charging seats, also known as electric vehicle charging stations or charging piles, are infrastructure specifically designed to provide charging services for electric vehicles. They can be installed in various locations such as public parking lots, residential areas, commercial areas, highway service areas, etc., so that electric vehicle users can charge their vehicles when needed. New energy charging seats are usually classified into several categories: AC charging (AC Charging): Slow charging: Using a lower power (generally 3kW to 22kW), the alternating current is converted into direct current through an on-vehicle charger, and then the battery is charged. This charging method usually takes several hours to overnight to complete the charging, and is suitable for overnight charging at home or in the office. DC fast charging (DC Fast Charging): This charging method uses high-power direct current to directly charge the battery, which can significantly reduce the charging time. Usually, the battery can be charged to 80% of the power within 30 minutes. The output power of DC fast charging stations can range from 50kW to 350kW or higher, depending on the technical specifications.

[0003] In the prior art, in order to improve the charging efficiency, a high-power charging seat is generally used for charging. However, due to the large input power, the temperature of the charging seat rises relatively fast. In order to solve the above problems, a high-voltage charging seat is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-voltage charging seat to solve the above problems, including:

[0005] A charging seat body, with DC terminals arranged at both ends of the middle part of the front side. A liquid-cooled terminal is arranged between the two DC terminals. Two cold water pipes are fixedly installed inside the liquid-cooled terminal. The outer walls of the two cold water pipes are both slidably connected with sleeves. Chutes are opened on both sides of the upper end inside the cold water pipes. Blocks are slidably connected inside the chutes. A buoyancy block is arranged on one side of the block.

[0006] Through the above technical solution, when the liquid-cooled charger head is connected to the charger base body, the liquid-cooled water port sleeve of the liquid-cooled charger head is arranged on the outer wall of the cold water pipe. During the charging process of the charger base, the coolant in the liquid-cooled charger head enters the inside of the cold water pipe through the liquid-cooled water port, and the coolant in the cold water pipe cools the DC terminal. At the same time, when the liquid-cooled water port sleeve is connected to the cold water pipe, the liquid-cooled water port pushes the sleeve downward. At this time, the resistance on the outer wall of the stopper disappears. When the coolant enters the cold water pipe, the buoyancy blocks on one side of the stopper move to both sides under the influence of buoyancy, squeezing the inner wall of the liquid-cooled water port. On the one hand, it facilitates the connection between the liquid-cooled water port and the cold water pipe, and on the other hand, it improves the sealing performance between the two.

[0007] Further, a limiting groove is provided at the upper end of the sliding groove, and a convex platform is integrally arranged at the upper end of the stopper, and the convex platform is slidably connected inside the limiting groove.

[0008] Further, a sealing gasket is fixedly installed on the outer wall of the upper end of the convex platform in contact with the upper wall of the limiting groove.

[0009] Through the above technical solution, the sealing performance is improved by setting the sealing gasket to prevent the leakage of the coolant.

[0010] Further, a high-voltage interlock terminal is provided below between the two DC terminals, and two interlock terminal holes are provided inside the high-voltage interlock terminal.

[0011] Through the above technical solution, the high-voltage charger base is protected by setting the high-voltage interlock terminal.

[0012] Further, a protective cover is hinged on the outer wall of one side of the charger base body.

[0013] Through the above technical solution, when the charger base body is not in use, the DC terminal is protected by closing the protective cover.

[0014] Further, a buckle is hinged on the outer wall of the other side of the charger base body, and a torsion spring is fixedly installed between the buckle and the charger base body.

[0015] Through the above technical solution, after the protective cover is closed, the position of the protective cover is fixed by the buckle.

[0016] Further, a connecting seat is integrally arranged on the outer wall of the charger base body, and threaded holes are provided at the four corners of the connecting seat.

[0017] Through the above technical solution, the charger base body is connected to the vehicle through the connecting seat.

[0018] To sum up, due to the adoption of the above technical solution, the beneficial effects of the present utility model are: the present utility model provides a high-voltage charger base.

[0019] After the liquid-cooled charger head is connected to the charger base body, the liquid-cooled water outlet sleeve of the liquid-cooled charger head is arranged on the outer wall of the cold water pipe. During the charging process of the charger base, the coolant in the liquid-cooled charger head enters the inside of the cold water pipe through the liquid-cooled water outlet, and the coolant in the cold water pipe cools down the DC terminal. At the same time, when the liquid-cooled water outlet sleeve is connected to the cold water pipe, the liquid-cooled water outlet pushes the sleeve downward. At this time, the resistance on the outer wall of the stopper disappears. When the coolant enters the cold water pipe, the buoyancy blocks on one side of the stopper move to both sides under the influence of buoyancy, squeezing the inner wall of the liquid-cooled water outlet. On the one hand, it facilitates the connection between the liquid-cooled water outlet and the cold water pipe, and on the other hand, it improves the sealing performance between the two.

[0026] The following will be combined with Figures 1-4 A detailed description will be given of a high-voltage charger base according to an embodiment of the present invention.

[0027] A high-voltage charger base includes:

[0028] The charging base body 1 is provided with DC terminals 2 at both ends of the middle part of its front side. A protective cover 11 is hinged on the outer wall of one side of the charging base body 1. When the charging base body 1 is not in use, the DC terminals 2 are protected by closing the protective cover 11. A buckle 12 is hinged on the outer wall of the other side of the charging base body 1. A torsion spring is fixedly installed between the buckle 12 and the charging base body 1. After the protective cover 11 is closed, the position of the protective cover 11 is fixed by the buckle 12. A connecting seat 16 is integrally arranged on the outer wall of the charging base body 1. Threaded holes are opened at the four corners of the connecting seat 16. The charging base body 1 is connected to the vehicle through the connecting seat; A liquid-cooled terminal 3 is arranged between the two DC terminals 2. Two cold water pipes 4 are fixedly installed inside the liquid-cooled terminal 3. A high-voltage interlock terminal 5 is arranged below between the two DC terminals 2. Two interlock terminal holes 6 are opened inside the high-voltage interlock terminal 5. The high-voltage charging base is protected by setting the high-voltage interlock terminal 5. When the liquid-cooled charging head is connected to the charging base body 1, the liquid-cooled water outlet sleeve of the liquid-cooled charging head is sleeved on the outer wall of the cold water pipe 4. During the charging process of the charging base, the coolant in the liquid-cooled charging head enters the inside of the cold water pipe 4 through the liquid-cooled water outlet, and the DC terminals 2 are cooled by the coolant in the cold water pipe 4; Sleeves 7 are slidably connected to the outer walls of the two cold water pipes 4. Sliding grooves 8 are opened on both sides of the upper end inside the cold water pipes 4. Blocks 9 are slidably connected inside the sliding grooves 8. Limit grooves 13 are opened at the upper ends of the sliding grooves 8. A boss 14 is integrally arranged at the upper end of the block 9. The boss 14 is slidably connected inside the limit groove 13. A sealing gasket 15 is fixedly installed on the outer wall of the upper end of the boss 14 in contact with the upper wall of the limit groove 13. The sealing performance is improved by setting the sealing gasket 15 to prevent the coolant from leaking. A buoyancy block 10 is arranged on one side of the block 9. When the liquid-cooled water outlet sleeve is connected to the cold water pipe 4, the liquid-cooled water outlet pushes the sleeve 7 downward. At this time, the resistance on the outer wall of the block 9 disappears. When the coolant enters the cold water pipe 4, the buoyancy block 10 on one side of the block 9 moves to both sides under the influence of buoyancy and squeezes the inner wall of the liquid-cooled water outlet. On the one hand, it is convenient for the liquid-cooled water outlet to be connected to the cold water pipe 4, and on the other hand, the sealing performance between the two is improved.

[0029] Working principle: When the liquid-cooled charging head is connected to the charging base body 1, the liquid-cooled water outlet sleeve of the liquid-cooled charging head is sleeved on the outer wall of the cold water pipe 4. During the charging process of the charging base, the coolant in the liquid-cooled charging head enters the inside of the cold water pipe 4 through the liquid-cooled water outlet, and the DC terminals 2 are cooled by the coolant in the cold water pipe 4. At the same time, when the liquid-cooled water outlet sleeve is connected to the cold water pipe 4, the liquid-cooled water outlet pushes the sleeve 7 downward. At this time, the resistance on the outer wall of the block 9 disappears. When the coolant enters the cold water pipe 4, the buoyancy block 10 on one side of the block 9 moves to both sides under the influence of buoyancy and squeezes the inner wall of the liquid-cooled water outlet. On the one hand, it is convenient for the liquid-cooled water outlet to be connected to the cold water pipe 4, and on the other hand, the sealing performance between the two is improved.
