Description

Technical Field

[0001] The present invention relates to an electrical connector device and an electric vehicle including the same. Background Art

[0002] Currently, the emission of automobile exhaust is still an important factor in environmental pollution problems. In order to control automobile exhaust, natural gas vehicles, hydrogen fuel vehicles, solar vehicles, and electric vehicles have been developed to replace fuel-powered vehicles. Among them, electric vehicles have the most promising application prospects. Currently, electric vehicles mainly include two types: direct charging type and quick replacement type. Due to the limitations of charging time and location, many new energy electric vehicles are gradually adopting the mode of quickly replacing batteries for energy replenishment.

[0003] When an electric vehicle replaces its battery, the battery swapping device removes the discharged battery from the electric vehicle and transfers the discharged battery to the battery transfer device. Then, the battery transfer device transfers the discharged battery to the battery warehouse for charging. After that, the battery transfer device takes out the fully charged battery from the battery warehouse and transfers the fully charged battery to the battery swapping device, and the battery swapping device installs the fully charged battery into the electric vehicle.

[0004] In existing electric vehicles, the cables on the electric vehicle are plugged into the sockets of the vehicle-end electrical connectors through plugs. Corresponding installation positions are set on the quick replacement brackets of the vehicle body. After the battery pack is placed in the installation position, it is connected to the vehicle-end electrical connector on the vehicle body through the battery-end electrical connector, and then fixed by a locking device. In this process, the electrodes of the battery-end electrical connector on the battery pack need to contact the electrodes on the vehicle-end electrical connector to ensure power output.

[0005] Currently, the installation position of the vehicle-end electrical connector is relatively fixed. The vehicle-end electrical connector is generally installed on the front beam of the quick replacement bracket. For electric vehicles with a front-wheel drive mode, the cable can be directly inserted into the socket of the vehicle-end electrical connector through the plug. For electric vehicles with a rear-wheel drive mode, the cable needs to be bent 180 degrees and then the plug is inserted into the socket of the vehicle-end electrical connector on the front beam. Due to the large turning amplitude of the cable and the detachable plug-and-socket connection between the plug and the socket, the electrical connection between the plug and the socket is likely to become loose, and even cause abnormal electrical connection failure or burnout, which easily affects the stable reliability and service life of the electrical connection. Summary of the Invention

One end of the electrical connection plug 2 is connected to the cable 3, and the other end of the electrical connection plug 2 is inserted into the electrical connection socket 12. By providing the insertion opening 111 on the housing 11, the electrical connection socket 12 is disposed within the housing 11 and extends out of the housing 11 through the insertion opening 111, facilitating the mutual insertion between the electrical connection plug 2 and the electrical connection socket 12, and the installation connection is very convenient.

[0079] The outer surface of the electrical connection plug 2 is provided with a first mounting ear 21 extending outward, and the first mounting ear 21 is connected to the outer surface of the housing 11. After the electrical connection plug 2 and the electrical connection socket 12 are mutually inserted, the electrical connection plug 2 is mounted and connected to the housing 11 through the first mounting ear 21, effectively strengthening the connection strength between the electrical connection plug 2 and the electrical connector body 1, effectively avoiding the disconnection between the electrical connection plug 2 and the electrical connection socket 12, and greatly improving the safety and stability of the electrical connection between the electrical connection plug 2 and the electrical connection socket 12.

[0080] In this embodiment, as Figure 2 , Figure 3 , Figure 4 and Figure 7 shown, the first mounting ear 21 has a connection hole 211, and the connection hole 211 is detachably connected to the housing 11 through a fastener. Specifically, the housing 11 is provided with a plug connection hole 113, the first mounting ear 21 is provided with a connection hole 211, the connection hole 211 and the plug connection hole 113 are correspondingly arranged, and the fastener is installed and connected into the plug connection hole 113 of the housing 11 through the connection hole 211. The first mounting ear 21 and the housing 11 adopt a detachable connection method, making the installation and disassembly very convenient, and the structure is simple and easy to process and manufacture.

[0081] The number of the first mounting ears 21 is two, and the two first mounting ears 21 are respectively disposed on both sides of the electrical connection plug 2. Both sides of the electrical connection plug 2 are respectively mounted and connected to the housing 11 through the first mounting ears 21, thereby realizing the fixation of both sides of the electrical connection plug 2, making the installation and connection between the electrical connection plug 2 and the housing 11 stable and reliable, effectively avoiding the disconnection phenomenon, and improving the safety and stability of the electrical connection between the electrical connection plug 2 and the electrical connection socket 12.

[0082] There is a first reinforcing rib 212 between the first mounting ear 21 and the electrical connection plug 2. The first reinforcing rib 212 can effectively strengthen the structural connection strength of the first mounting ear 21, thereby improving the connection stability and reliability between the electrical connection plug 2 and the housing 11 and the electrical connection socket 12, and extending the service life of the electrical connector device.

[0083] As Figure 4 , Figure 5 and Figure 6 shown, the outer surface of the electrical connection socket 12 is provided with a second mounting ear 121 extending outward, and the second mounting ear 121 is connected to the inner wall surface of the housing 11. The first mounting ear 21 of the electrical connection plug 2 is located outside the housing 11 and connected to the outer surface of the housing 11, and the second mounting ear 121 of the electrical connection socket 12 is located inside the housing 11 and connected to the inner wall surface of the housing 11, so that there is no interference between the electrical connection socket 12 and the electrical connection plug 2, and the structure is compact. At the same time, the electrical connection socket 12 is connected to the housing 11 through the second mounting ear 121, thereby strengthening the connection strength between the electrical connection socket 12 and the housing 11, effectively avoiding the separation between the electrical connection plug 2 and the electrical connection socket 12, and further improving the safety and stability of the electrical connection between the electrical connection plug 2 and the electrical connection socket 12.

[0084] There is a blind hole 1211 on the second mounting ear 121, and there is a mounting hole 112 on the housing 11. The fastener passes through the mounting hole 112 and is connected to the blind hole 1211. The fastener can pass through the outside of the housing 11 through the mounting hole 112 and be installed and connected in the blind hole 1211, so that the second mounting ear 121 and the housing 11 are installed and connected together, so that there is no need to extend into the inside of the housing 11 for installation and connection, effectively avoiding abnormal contact when extending into the inside of the housing 11, and realizing very convenient installation and disassembly; at the same time, the use of the blind hole 1211 and the mounting hole 112 has a simple structure and is convenient for processing and manufacturing.

[0085] The number of the second mounting ears 121 is two, and the two second mounting ears 121 are respectively arranged on both sides of the electrical connection socket 12. Both sides of the electrical connection socket 12 are respectively installed and connected to the housing 11 through the second mounting ears 121, so as to fix both sides of the electrical connection socket 12, make the installation connection between the electrical connection socket 12 and the housing 11 stable and reliable, effectively avoid the separation phenomenon, and improve the safety and stability of the electrical connection between the electrical connection socket 12 and the electrical connection plug 2.

[0086] There is a socket reinforcing rib 1212 between the second mounting ear 121 and the electrical connection socket 12. The socket reinforcing rib 1212 can effectively strengthen the structural connection strength of the second mounting ear 121, thereby improving the connection stability and reliability between the electrical connection socket 12 and the electrical connection plug 2, and extending the service life of the electrical connector device. Among them, the socket reinforcing rib 1212 can correspond to the blind hole 1211, so that the blind hole 1211 can be recessed inward into the socket reinforcing rib 1212 to extend the depth of the blind hole 1211 to strengthen the connection strength between the electrical connection socket 12 and the housing 11.

[0087] As Figure 4 , Figure 6 and Figure 7 shown, the end face of the electrical connection plug 2 facing the electrical connector body 1 has a sealing ring 26. The sealing ring 26 abuts against the housing 11 and seals and covers the insertion port 111. The electrical connection plug 2 and the electrical connection socket 12 are inserted into each other. The sealing ring 26 is compressed between the electrical connection plug 2 and the housing 11. The insertion port 111 is sealed and covered through the sealing ring 26, effectively preventing external water, impurities, etc. from entering the electrical connector body 1, and the safety and stability are higher. At the same time, the floating electrical connection between the electrical connection plug 2 and the housing 23 can be realized through the sealing ring 26, further ensuring the stability of the electrical connection between the electrical connection plug 2 and the electrical connection socket 12. And the sealing ring 26 is located outside the housing 11 and is arranged on the end face of the electrical connection plug 2, and the installation and connection are very convenient. Among them, the end face of the electrical connection plug 2 facing the electrical connector body 1 has a sealing groove, and the sealing ring 26 is embedded in the sealing groove to play a positioning role, and the stability is higher.

[0088] As Figure 2 , Figure 3 and Figure 7 shown, the outer surface of the electrical connection plug 2 is provided with a third mounting ear 22 for connecting with an electric vehicle. The electrical connection plug 2 is connected to the electric vehicle through the third mounting ear 22, thereby fixing the electrical connection plug 2, effectively avoiding the offset and dislocation of the electrical connection plug 2, and greatly improving the stability and reliability of the electrical connector device.

[0089] Specifically, a connection through hole 222 is opened on the third mounting ear 22, and the third mounting ear 22 is connected to the electric vehicle through the connection through hole 222. The number of the third mounting ears 22 is two, and the two third mounting ears 22 are respectively arranged on both sides of the electrical connection plug 2, so as to fix both sides of the electrical connection plug 2. The electrical connection plug 2 is connected to the quick-change bracket on the electric vehicle through the third mounting ear 22.

[0090] There is a second reinforcing rib 221 between the third mounting ear 22 and the electrical connection plug 2. The second reinforcing rib 221 can effectively enhance the structural connection strength of the third mounting ear 22, effectively avoid the occurrence of detachment, thereby improving the connection stability and reliability between the electrical connection plug 2 and the electric vehicle, and extending the service life of the electrical connector device.

[0091] As Figure 2 , Figure 6 and Figure 7 shown, the electrical connection plug 2 includes a housing 23 and a plug-in piece 24. The housing 23 includes a cable installation part 233, a vertical part 232, and a plug-in installation part 231. One ends of the cable installation part 233 and the plug-in installation part 231 are respectively connected to the top and bottom of the vertical part 232, and the other ends of the cable installation part 233 and the plug-in installation part 231 both extend in the same direction along the horizontal direction, so that the shape among the cable installation part 233, the vertical part 232, and the plug-in installation part 231 is in an inverted U shape.

The plug-in piece 24 is arranged in the plug-in installation part 231 and is electrically connected to the cable 3, and the plug-in piece 24 is plugged into the electrical connection socket 12.

[0092] The plug-in piece 24 is arranged to be plugged into the electrical connection socket 12. The cable 3 is used to be plugged into the cable installation part 233 and is electrically connected to the plug-in piece 24. The overall shape of the housing 23 is in an inverted U shape through the cable installation part 233, the vertical part 232, and the plug-in installation part 231. The inverted U shape enables the cable 3 not to need to turn 180 degrees to adjust the direction, so that the extending direction of the cable 3 is consistent with the plugging direction of the plug-in piece 24. The cable 3 can extend to the rear end of the electric vehicle and be connected to electrical equipment such as a generator at the rear end of the electric vehicle; the plug-in piece 24 moves along the plugging direction to enable the plug-in piece 24 to be plugged into the electrical connection socket 12, realizing the electrical connection between the plug-in piece 24, the cable 3, and the electrical connection socket 12. Moreover, the cable 3 can realize the electrical connection between the cable 3 of the rear-wheel drive electric vehicle and the electrical connector body 1 without turning and adjusting the direction outside the electrical connection plug 2; through the fixed connection of the plug-in piece 24 and the electrical connection socket 12 to the cable 3, the cable 3 is prevented from shaking, effectively avoiding the occurrence of electrical connection loosening, greatly improving the stability and reliability of the electrical connector device, and extending the service life of the electrical connector device. At the same time, the shape of the plug-in piece 24 is sheet-like. The plug-in piece 24 is plugged into the electrical connection socket 12 in a sheet-like manner, achieving a large contact area, a small contact resistance, good electrical conductivity, stable and reliable electrical connection, and low cost.

One end of the flexible conductive member 25 is connected to the cable 3, and the other end of the flexible conductive member 25 is connected to the insertion piece 24. The flexible conductive member 25 is located within the vertical portion 232, and both ends of the flexible conductive member 25 are respectively connected to the cable 3 within the cable mounting portion 233 and the insertion piece 24 within the insertion mounting portion 231, thereby realizing the electrical connection between the cable 3, the flexible conductive member 25, the insertion piece 24, and the electrical connection socket 12. The electrical connection plug 2 is electrically connected to the cable 3 and the electrical connection socket 12 through the flexible conductive member 25, enabling the cable 3 to be free from turning and adjusting its direction within the housing 23. At the same time, the flexible conductive member 25 itself can deform, and has a small turning radius. Through the flexible conductive member 25, a floating electrical connection is achieved between the cable 3 and the electrical connection socket 12, effectively avoiding electrical connection failure and greatly enhancing the reliability and service life of the electrical connector device during electrical connection.

[0094] As Figure 1 shown, the electrical connector body 1 further includes a pole column 13. One end of the pole column 13 facing the electrical connection plug 2 extends into the outer housing 11 and is connected to the electrical connection socket 12. A plurality of conductive elastic members 131 are provided on the side of the pole column 13 facing away from the electrical connection plug 2. The plurality of conductive elastic members 131 are all used to be connected to the battery terminal electrical connector. One end of the pole column 13 is connected to the electrical connection socket 12, and the other end is connected to the battery terminal electrical connector through the plurality of conductive elastic members 131. Through the plurality of conductive elastic members 131, a floating connection is realized between the pole column 13 and the battery terminal electrical connector, making the electrical connection more stable. Especially in electrical connection applications under dynamic load and vibration environment conditions, it effectively avoids abnormal situations such as electrical connection failure or burning caused by loose connection, and greatly enhances the reliability and service life of the electrical connection. At the same time, a large contact area is achieved between the pole column 13 and the battery terminal electrical connector, the contact resistance is relatively small, the electrical conductivity is good, and the electrical connection is more stable and reliable.
