In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0028] like Figures 1 to 8 As shown, this embodiment satisfies the connection device for rapid replacement of batteries in multiple modes, including a plug body 1 and a mounting seat 2, a fixing block 3 is provided in the middle of the front end of the plug body 1, and plug seats 4 are installed on the upper and lower surfaces of the fixing block 3. By providing two plug seats 4, the socket and the plug can be connected from two directions, and a sealing gasket 5 is installed at the front end of the plug body 1 outside the plug seat 4. The sealing gasket 5 is used to ensure the sealing when the plug and the socket are connected to prevent external dust and water from entering the plug and the socket. Insertion rods 6 are installed on both sides of the sealing gasket 5. A socket body 7 is installed at the front end of the mounting seat 2, and a protective shell 8 is installed outside the socket body 7. The protective shell 8 is used to protect the socket body 7. Guide sleeves 9 are installed at both ends of the outer side of the protective shell 8, and a sealing cover 10 is installed in front of the protective shell 8. The sealing cover 10 is installed at the front end of the sealing cover 10 through a connecting component. The sealing cover 10 is used to connect the protective shell 8 on the surface of the socket body 7 to achieve protection of the socket body 7.

[0029] Specifically, the cross-section of the fixing block 3 is an isosceles right triangle, the inclined surface of the fixing block 3 is in contact with the front end of the plug body 1, the two plug sockets 4 are arranged perpendicular to each other, and the socket is installed by horizontal plugging and vertical plugging, which is convenient for selecting a suitable installation method for the socket according to actual needs. The angle between the two plug rods 6 is a right angle, and the diameter of the plug rod 6 matches the internal diameter of the guide sleeve 9. When the plug and the socket are connected, the plug rod 6 is inserted into the guide sleeve 9 at both ends of the protective shell 8, which plays a guiding role in the connection between the plug and the socket.

[0030] Furthermore, a grounding pin 12 and a connecting pin 13 are installed inside the plug socket 4, and a grounding socket 14 and a connecting socket 26 are correspondingly arranged inside the socket body 7. One end of the grounding socket 14 is in contact with the protective shell 8. The protective shell 8 is made of metal material, and a grounding hole 19 is provided on the surface of the protective shell 8. When the plug and the socket are connected, the grounding pin 12 is inserted into the grounding socket 14, and then the grounding wire is installed in the grounding hole 19 with a bolt, so as to realize grounding of the battery exchange box and the equipment circuit. The area of ​​the grounding pin 12 is increased from 13 square millimeters to 16 square millimeters, and the terminal diameter is changed from 4 to 5, which is applicable to the new national standard requirements.

[0031] Furthermore, a protective groove 15 is arranged at one end of the sealing cover 10, and a high-pressure sealing ring 16 is installed inside the protective groove 15. Connecting blocks 27 are installed at both ends of the sealing cover 10. A connecting rod 25 is installed at one end of the connecting block 27 close to the protective groove 15. The diameter of the connecting rod 25 matches the inner diameter of the guide sleeve 9. When the sealing cover 10 is installed on the protective shell 8, the protective shell 8 is inserted into the sealing cover 10, and one end of the protective shell 8 contacts the high-pressure sealing ring 16. The protective shell 8 compresses the high-pressure sealing ring 16, thereby effectively ensuring the sealing of the sealing cover 10 during installation, realizing protection of the socket body 7, and preventing external debris from entering the socket body 7.

[0032] Furthermore, the connecting assembly includes a snap ring 1101, a clamping block 1102 and a shifting block 1103. The snap rings 1101 are installed on both sides of the upper and lower ends of the sealing cover 10 above and below the protective groove 15, and the clamping blocks 1102 are installed on both sides of the upper and lower ends of the protective shell 8. The clamping blocks 1102 are respectively located inside the snap rings 1101, and the upper ends of the snap rings 1101 on one side of the clamping blocks 1102 are installed with shifting blocks 1103. When the sealing cover 10 is installed, the snap ring 1101 is sleeved on the surface of the clamping block 1102, thereby realizing the connection between the sealing cover 10 and the upper and lower parts of the protective shell 8. The setting of the shifting block 1103 makes it easy to shift the snap ring 1101, to remove the snap ring 1101 from the surface of the clamping block 1102, and to disassemble the sealing cover 10.

[0033] Furthermore, a vertical surface 17 is provided on the surface of one end of the clamping block 1102 close to the shifting block 1103, and an arc surface 18 is provided on the surface of the end of the clamping block 1102 away from the shifting block 1103. The setting of the vertical surface 17 can effectively prevent the retaining ring 1101 from falling off the surface of the clamping block 1102, and the setting of the arc surface 18 allows the retaining ring 1101 to be directly sleeved on the surface of the clamping block 1102 when passing through the clamping block 1102.

[0034] Furthermore, the rear ends of the connecting pins 13 are all extended to the rear part of the plug body 1, and the rear ends of the connecting pins 13 in the upper plug seat 4 are all installed with connecting plates 20, and the surface of the connecting plates 20 is provided with connecting holes, and the rear ends of the connecting pins 13 in the lower plug seat 4 are all provided with threaded holes 21, and the rear ends of the connecting pins 13 in the lower plug seat 4 are all installed with solder layers 22, and one end of the solder layer 22 is in contact with the connecting plate 20. By using bolts to pass through the internal electrodes of the battery swap box and the connecting holes on the connecting plate 20, and through the solder layer 22, and installing the bolts in the threaded holes 21, the two plug seats 4 can be connected. The connection of the lower connecting pins 13 ensures that the two plug sockets 4 can charge and discharge the battery swap box, effectively ensuring the effective use of the two plug sockets 4. At the same time, since the solder layer 22 is relatively soft, when the connecting plate 20 and the lower connecting pins 13 are connected by bolts, the connecting plate 20 and the lower connecting pins 13 squeeze the solder layer 22. The solder layer 22 can fill the gap between the connecting plate 20 and the lower connecting pins 13, effectively avoiding heat caused by the gap between the connecting plate 20 and the lower connecting pins 13, and ensuring the tightness of the connection between the connecting plate 20 and the lower connecting pins 13.

[0035] Furthermore, one end of the protective shell 8 is in contact with the front end of the sealing gasket 5, and limiting grooves 23 are provided on the upper and lower parts of the front end of the plug body 1 behind the sealing gasket 5. A protrusion 24 is provided inside the limiting groove 23 at the rear end of the sealing gasket 5. When the sealing gasket 5 is installed, the protrusion 24 at the rear end of the sealing gasket 5 is located inside the limiting groove 23, which effectively prevents the protective shell 8 from pushing the sealing gasket 5 when it contacts with the sealing gasket 5, and effectively prevents the sealing gasket 5 from accidentally moving. The sealing gasket 5 is installed on the surface of the battery exchange box, which is convenient for checking the wear of the sealing gasket 5 to prevent the sealing gasket 5 from losing its sealing effect.

[0036] The method of using this embodiment is as follows: when using the connection device that meets the requirements of rapid battery replacement in multiple modes, the socket is first installed by horizontal and vertical plugging. During this process, the guide sleeves 9 at both ends of the external protective shell 8 of the socket body 7 are inserted into the surfaces of the plug rods 6 on both sides of the plug body 1. The guide sleeves 9 and the plug rods 6 guide the installation of the socket body 7. When the socket body 7 is installed inside the plug socket 4, the grounding pin 12 is inserted into the grounding socket 14, and the connecting pin 13 is inserted into the connecting socket 26. The device circuit and the battery exchange box can be connected through the socket body 7 to facilitate charging and discharging the battery exchange box. Then the grounding wire is installed in the grounding hole 19 with bolts to realize grounding of the battery exchange box and the device circuit. When the socket body 7 is not connected to the plug body 1, the sealing cover 10 is sleeved on the surface of the protective shell 8 and fixed with a snap-on assembly. The sealing cover 10 can protect the socket body 7.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
