Description

Technical Field

[0001] This utility model relates to the field of battery swapping technology, specifically to a high- and low-voltage connector, a base, a battery box, and a battery swapping system. Background Technology

[0002] In existing high and low voltage connector technologies, a split-unit structure is typically used to achieve power transmission. The first and second units are respectively equipped with a high-voltage conductive unit and a low-voltage conductive element. The high-voltage unit, made of conductive metal, is responsible for high-voltage, high-current transmission; the low-voltage element uses shielded cables to transmit low-voltage signals. Patent document CN119787005A discloses a liquid-cooled connector and its liquid-cooled terminal assembly. In the liquid-cooled terminal assembly of this invention, coolant for one liquid-cooled cable flows in from a flow hole at the rear end of the corresponding terminal, flows through a terminal flow channel and flow element into the flow hole of the other terminal, and then flows back to the other liquid-cooled cable, achieving a circulating flow of coolant, thereby cooling the conductors and positive and negative terminals of the liquid-cooled cable. However, because the high-voltage unit and the low-voltage element need to be synchronously connected within a limited space, the internal wiring density of the connector increases significantly. Excessive cable arrangement not only occupies installation space but also easily leads to assembly failures such as wire tangling and contact misalignment. Especially in high-voltage transmission units, insufficient spacing between adjacent high-voltage contacts can easily lead to the superposition of electric fields, resulting in problems such as increased leakage current and partial discharge, which seriously affect the efficiency of power transmission and may even pose safety hazards.

[0051] In this embodiment, in a traditional high-low voltage connector structure, when the first unit 11 of the first connecting component 01 and the second unit 21 of the second connecting component 02 are plugged in, there is a technical defect of uneven electric field distribution in the electrical connection area between the first high-voltage unit 12 and the second high-voltage unit 22. Because the two sets of first high-voltage units 12 are densely arranged in a limited space, the physical distance between them and the adjacent second high-voltage units 22 is compressed to below a critical value. This results in insufficient air dielectric insulation strength between adjacent conductors when the high-voltage units conduct high-voltage current, leading to problems such as increased leakage current and partial discharge, seriously affecting the power transmission efficiency and even posing safety hazards. This embodiment provides a high-low voltage connector, such as... Figure 1 As shown, the high-low voltage connector includes a first connecting component 01 and a second connecting component 02. Figure 2As shown, the first connection component 01 may include a first base unit 11, two first high-voltage units 12, and a first low-voltage component 13. The first base unit 11 may be connected to the first high-voltage units 12. The first base unit 11 may be connected to the first low-voltage component 13. The two sets of first high-voltage units 12 may be arranged at intervals. The first low-voltage component 13 may be arranged within the interval area between the two sets of first high-voltage units 12. The first high-voltage units 12 and the first low-voltage component 13 may be arranged at intervals.

[0052] like Figure 5 As shown, the second connection component 02 may include a second base unit 21, two second high-voltage units 22, and a second low-voltage component 23. The second base unit 21 can be connected to the second high-voltage units 22. The second base unit 21 can be connected to the second low-voltage component 23. The two sets of second high-voltage units 22 can be spaced apart. The second low-voltage component 23 can be located within the spaced area between the two sets of second high-voltage units 22. The second high-voltage units 22 and the second low-voltage component 23 can be spaced apart.

[0053] The high-voltage and low-voltage connectors can include a plugged-in state and a disconnected state. In the plugged-in state, the first connector 11 and the second connector 21 are engaged, the first high-voltage unit 12 and the second high-voltage unit 22 are electrically connected, and the first low-voltage component 13 and the second low-voltage component 23 can be electrically connected. The two sets of high-voltage units are spaced apart to reduce the risk of short circuits between the first high-voltage unit 12 and the second high-voltage unit 22 in the event of damage to either unit.

[0054] In this embodiment, the first unit 11 may include a first seat body 111, a first flange 112, and a package body 113. For example... Figure 4 As shown, one side of the first flange 112 can be connected to the first base 111, and the other side can be connected to the enclosure 113. The enclosure 113 can be a hollow cavity. The first high-voltage unit 12 can be connected to the first flange 112. The first low-voltage unit 13 can be connected to the first flange 112. The first high-voltage unit 12 can penetrate through the first base 111 and the first flange 112. The first low-voltage unit 13 can penetrate through the first base 111 and the first flange 112. At least a portion of the first high-voltage unit 12 and at least a portion of the first low-voltage unit 13 can be disposed within the hollow cavity of the enclosure 113.

[0055] The second unit 21 may include a second seat body 211, a second flange 212, and a cover body 213. For example... Figure 7As shown, one side of the second flange 212 can be connected to the second base 211, and the other side can be connected to the encapsulated body 213. The encapsulated body 213 can be a hollow cavity. The second high-voltage unit 22 can be connected to the second flange 212. The second low-voltage unit 23 can be connected to the second flange 212. Both the second high-voltage unit 22 and the second low-voltage unit 23 can be disposed within the hollow cavity of the encapsulated body 213 to prevent external dust particles from entering the conductive area inside the encapsulated body 213.

[0056] The insertion state can also include the enclosed body 213 extending into the package 113. The nested structure of the package 113 and the enclosed body 213 forms a physical isolation layer, and the cavity structure prevents external dust from entering. Combined with the flange connection, it ensures the cleanliness of the connection component and prevents external dust particles from entering the conductive area inside the cavity and interfering with the insertion state.

[0057] In this embodiment, as Figure 3 As shown, the first unit 11 may further include a guide hole 114. The guide hole 114 may be a hollow tubular structure. One end of the guide hole 114 may be connected to the first flange 112, and the other end may extend away from the first flange 112. The guide hole 114 and the enclosure 113 may be on the same side of the first flange 112. This structure can provide an axial positioning reference for the insertion operation.

[0058] like Figure 5 As shown, the second unit 21 may further include a guide post 214. One end of the guide post 214 may be connected to the second flange 212, and the other end may extend away from the second flange 212. The guide post 214 and the encased body 213 may be on the same side of the second flange 212. The guide post 214 and the encased body 213 may be spaced apart. The insertion state may also include the inner peripheral wall of the guide hole 114 abutting against the outer peripheral wall of the guide post 214. The cooperation between the tubular guide hole 114 and the columnar guide post 214 forms a mechanical guiding structure, which uses axial guidance to achieve precise alignment, reduces the difficulty of insertion operation, reduces the risk of poor contact caused by installation deviation, and improves the assembly efficiency and reliability of the connector.

[0059] In this embodiment, as Figure 7 As shown, the second unit 21 may also include a sealing ring 215. The sealing ring 215 can be connected to the outer peripheral wall of the encapsulated body 213. The insertion state may also include the encapsulated body 113 abutting against the sealing ring 215. The sealing ring 215 can be made of elastic material, and the sealing ring 215 forms an annular contact surface between the encapsulated body 113 and the encapsulated body 213, enhancing the airtightness of the connection interface and preventing external contaminants from entering the cavity.

[0060] In this embodiment, as Figure 3As shown, the first high-voltage unit 12 may include a first high-voltage body 121 and a first high-voltage head 122. The first high-voltage head 122 may be configured as a hollow tube. The first high-voltage body 121 may wrap around the circumference of the first high-voltage head 122. The first high-voltage body 121 may be connected to the first flange 112. The first high-voltage head 122 may be spaced apart from the first low-voltage body 13. The first high-voltage body 121 may penetrate through the first base 111 and the first flange 112. The first high-voltage head 122 may penetrate through the first base 111 and the first flange 112. The first high-voltage head 122 may be connected to the first base 111.

[0061] like Figure 6 As shown, the second high-voltage unit 22 may include a second high-voltage conductor 221 and a second high-voltage connector 222. The second high-voltage conductor 221 may be connected to the second high-voltage connector 222. The second high-voltage conductor 221 may be connected to the second flange 212. The second high-voltage connector 222 may be spaced apart from the second low-voltage conductor 23. The second high-voltage conductor 221 may penetrate through the second base 211 and the second flange 212. The second high-voltage connector 222 may penetrate through the second base 211 and the second flange 212. The second high-voltage connector 222 may be connected to the second base 211.

[0062] The plug-in state can also include partial insertion of the second high-voltage connector 222 into the hollow cavity of the first high-voltage connector 122, allowing for electrical connection between the first high-voltage connector 122 and the second high-voltage connector 222. Through a double-layer insulation structure design, the first high-voltage connector 121 wraps around the conductive high-voltage connector to form a radial insulation layer, which, combined with the axial insertion connection, achieves electric field enclosure, ensuring reliable current transmission while effectively reducing the short-circuit risk between the first high-voltage connector 121 and the second high-voltage connector 221.

[0063] In this embodiment, as Figure 2 As shown, the first connecting assembly 01 may further include a first ground wire 14. The first ground wire 14 can be connected to the first flange 112. The first ground wire 14 can pass through the first base 111 and the first flange 112. At least a portion of the first ground wire 14 can be disposed within the hollow cavity of the enclosure 113. This structure provides a dedicated grounding channel for the high-voltage unit.

[0064] like Figure 5 As shown, the second connecting assembly 02 may further include a second ground wire 24. The second ground wire 24 can be connected to the second flange 212. The second ground wire 24 can pass through the second base 211 and the second flange 212. At least a portion of the second ground wire 24 can be disposed within the hollow cavity of the enclosure 113. This design forms a complete grounding loop.

[0065] The plug-in state can also include an electrical connection between the first ground wire 14 and the second ground wire 24. The first ground wire 14 passes through the first base 111 and the first flange 112 to form a continuous conductive path, and the second ground wire 24 passes through the second base 211 and the second flange 212 to form a continuous conductive path. Simultaneously, the first ground wire 14 and the second ground wire 24 are electrically connected, achieving interconnection of grounding lines during plug-in, establishing a reliable and safe grounding system, effectively releasing the risk of leakage current, and meeting electrical safety specifications.

[0066] In this embodiment, the first ground wire 14 can be disposed within the interval region between two first high-voltage units 12, and the first ground wire 14 can be spaced apart from the first high-voltage units 12. The first ground wire 14 can be spaced apart from the first low-voltage unit 13. The second ground wire 24 can be disposed within the interval region between two second high-voltage units 22, and the second ground wire 24 can be spaced apart from the second high-voltage units 22. The second ground wire 24 can be spaced apart from the second low-voltage unit 23. By centrally disposing of the ground wires within the interval region of the high-voltage units, a conductive isolation zone is formed, utilizing the conductor characteristics of the ground wires to absorb stray currents generated by adjacent high-voltage units. The spaced ground wires from the high-voltage units form a safe isolation distance, preventing the risk of short circuits caused by high-voltage arcs breaking down the air medium.

[0067] This embodiment discloses a base support, which may include a first connecting component 01 or a second connecting component 02 of a high-low voltage connector as described in any of the above embodiments. The base support may also include a base assembly 03, such as... Figure 9 As shown, the base assembly 03 may include a base frame unit 31, a guide unit 32, a locking unit 33, and a connecting seat unit 34. The guide unit 32 can be connected to the base frame unit 31. The locking unit 33 can be connected to the base frame unit 31. Figure 8 As shown, the connecting unit 34 may include a connecting plate 341, a spring 342, and a bolt 343. One end of the spring 342 can abut against the connecting plate 341, and the other end can abut against the base frame unit 31. The bolt 343 can sequentially connect the connecting plate 341, the spring 342, and the base frame unit 31. This structure achieves buffer positioning of the connecting components through an elastic support system. The connecting plate 341 can be detachably connected to the first base unit 11 or the second base unit 21. Precise positioning is achieved through the cooperation of the guide unit 32 and the battery frame unit 41, combined with the buffer structure of the spring 342 to absorb the installation impact force. The locking unit 33 and the connecting plate 341 work together to form a multiple fixing mechanism, ensuring a stable connection between the battery box and the vehicle while retaining the function of quick disassembly and assembly, facilitating the installation and fixing of the battery box on the vehicle.

The battery unit 42 and the battery frame unit 41 may be detachably connected. The first base unit 11 may be detachably connected to the battery frame assembly 04. The battery unit 42 may be electrically connected to the first high-voltage unit 12 and the first low-voltage unit 13, respectively. Alternatively, the second base unit 21 may be detachably connected to the battery frame assembly 04, and the battery unit 42 may be electrically connected to the second high-voltage unit 22 and the second low-voltage unit 23, respectively. The modular frame design allows the battery unit 42 to be replaced independently, and the detachable base unit enables quick switching of electrical connection interfaces. The high-voltage unit and the low-voltage unit are respectively connected to the battery unit 42 to form independent power supply circuits, meeting the requirements for separate transmission of high and low voltage circuits.
