[0044] The present invention provides a transfer charging socket 100 for use in electric vehicles.

[0045] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4In an embodiment of the present invention, the adapter charging socket 100 includes a connecting seat 1 and an adapter seat 2, wherein the connecting seat 1 is installed on the electric vehicle, and the connecting seat 1 is provided with a plurality of first terminals 14 arranged at intervals, and each first terminal 14 is provided with a plug-in slot 142 at one end facing away from the electric vehicle; the adapter seat 2 is provided with a plurality of second terminals 25 arranged at intervals, and the adapter seat 2 is detachably connected to the end of the connecting seat 1 facing away from the electric vehicle, and one end of each second terminal 25 is detachably accommodated and limited in the plug-in slot 142 of a first terminal 14, and each second terminal 25 is provided with a terminal jack 252 corresponding to the charging pin of the charging gun at one end facing away from the first terminal 14.

[0046] In this embodiment, the adapter charging socket 100 includes two parts, a connecting seat 1 and an adapter seat 2, which are detachably connected. The connecting seat 1 is installed on the electric vehicle and is used to connect to the power supply component of the electric vehicle. The adapter seat 2 is detachably connected to the end of the connecting seat 1 facing away from the electric vehicle. This makes it convenient for the electric vehicle to be connected to an external power supply device, such as a charging pile and a charging gun, through the connecting seat 1 and the adapter seat 2 of the adapter charging socket 100 to charge the electric vehicle.

[0047] It can be understood that in order to facilitate the disassembly and replacement of the adapter seat 2, the connecting seat 1 and the adapter seat 2 adopt a detachable connection method such as a snap connection, plug-in fit, screw connection, pin connection or threaded connection, which is not limited here.

[0048] In this embodiment, the connection base 1 is provided with a plurality of first terminals 14, one end of the first terminal 14 is connected to the power supply component of the electric vehicle, and the other end of the first terminal 14 is provided with a plug-in slot 142 for connecting and conducting with the adapter 2. The adapter 2 is provided with a plurality of second terminals 25 corresponding to the plurality of first terminals 14, one end of the second terminal 25 is detachably accommodated and limited in the plug-in slot 142 of the first terminal 14, so that the connection and conduction between the second terminal 25 and the first terminal 14 is realized, and the other end of the second terminal 25 is provided with a terminal jack 252, so that the charging pin of the charging gun can be conveniently inserted into the terminal jack 252, so that the charging pin of the charging gun is connected with the electric vehicle through the second terminal 25 and the first terminal 14, forming a charging path.

[0049] The adapter charging socket 100 of the present invention adopts two parts of a connecting seat 1 and an adapter seat 2 that can be detachably connected. The connecting seat 1 is installed on the electric vehicle, and a first terminal 14 with a plug-in slot 142 is arranged on the connecting seat 1. By arranging a second terminal 25 on the adapter seat 2, the second terminal 25 is plugged into and matched with the plug-in slot 142 of the first terminal 14 to achieve conduction. A terminal socket 252 corresponding to the charging pin of the charging gun is provided at one end of the second terminal 25 facing away from the first terminal 14. When a faulty terminal socket 252 needs to be replaced, the adapter seat 2 containing the faulty second terminal 25 can be directly removed and replaced, thereby realizing the replacement of the terminal socket 252 of the adapter charging socket 100. The adapter charging socket 100 of the present invention can replace only a portion of the second terminal 25 of the terminal jack 252 that is worn or faulty, retain the second terminal 25 and the connecting socket 1 of the rest of the adapter socket 2, and reuse them, thereby improving the utilization rate of the adapter charging socket 100 and saving the cost of maintaining the adapter charging socket. At the same time, the structure makes it easy to quickly disassemble the adapter socket 2 from the connecting socket 1 and take out the second terminal 25 for replacement, which greatly reduces the difficulty of replacement and improves replacement efficiency.

[0050] It is understandable that the adapter charging socket 100 of the present invention can directly replace the entire adapter 2. Of course, the adapter 2 can also be disassembled from the connecting seat 1, and a part of the second terminal 25 that is worn or faulty in the adapter 2 can be replaced. Of course, in order to improve the versatility of the adapter charging socket 100 and to be applicable to charging guns of different models or specifications, the adapter 2 and the connecting seat 1 are set to be detachably connected, and different types of adapters 2 can be replaced to facilitate the adapter 2 to match charging guns of different models or specifications, which is not limited here.

[0051] During use, the part of the adapter charging socket 100 that fails is usually the part that contacts the charging pin of the charging gun, that is, the terminal jack 252 of the second terminal 25. The second terminal 25 is connected to the first terminal 14, and the two are electrically connected to form a charging path. The second terminal 25 and the first terminal 14 are detachably connected. When the adapter 2 or the second terminal 25 in the adapter 2 needs to be replaced, the second terminal 25 is replaced or repaired after the adapter 2 is removed.

[0052] It can be understood that the multiple first terminals 14 of the connecting seat 1 can be terminals of multiple different models or specifications, and the multiple second terminals 25 of the adapter seat 2 can be terminals of multiple different models or specifications, and the multiple second terminals 25 of the adapter seat 2 correspond one-to-one to the multiple first terminals 14 of the connecting seat 1.

[0053] In one embodiment, if Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the adapter 2 includes a mounting shell 21 and a terminal pressing plate 22, wherein the mounting shell 21 is in the shape of a cylinder with two ends open, and a plurality of first accommodating cavities 211 arranged at intervals are provided in the mounting shell 21, and a first limiting block 212 is convexly provided on the cavity wall of one end of each first accommodating cavity 211 away from the connecting seat 1; the terminal pressing plate 22 is detachably accommodated in the mounting shell 21, and a mounting hole 221 is provided in the terminal pressing plate 22 corresponding to each first accommodating cavity 211. One end of each second terminal 25 is accommodated in a first accommodating cavity 211 and is limitedly abutted against the first limiting block 212, and the other end passes through the mounting hole 221 to be detachably accommodated and limited in the plug-in slot 142 of a first terminal 14.

[0054] Specifically, the mounting shell 21 serves to install and protect the second terminal 25. The mounting shell 21 is configured as a cylindrical structure with openings at both ends. On the one hand, it is beneficial for one end of the second terminal 25 arranged in the mounting shell 21 to be connected and conducted with the first terminal 14 of the connecting seat 1 through the opening at one end of the mounting shell 21. On the other hand, the other end of the second terminal 25 is connected and conducted with the charging pin of the charging gun through the opening at the other end of the mounting shell 21.

[0055] It can be understood that an installation space is formed in the installation shell 21. In order to realize the installation and fixation of the second terminal 25 and facilitate the disassembly of the second terminal 25, a bracket structure is formed in the installation space of the installation shell 21. The bracket structure forms a plurality of first accommodating cavities 211 arranged at intervals in the installation space of the installation shell 21, so as to facilitate the installation of the plurality of second terminals 25 in the plurality of first accommodating cavities 211, and to separate them from each other, so as to avoid mutual influence and interference between the plurality of second terminals 25. At the same time, the first accommodating cavity 211 can protect the second terminal 25, and prevent the second terminal 25 from shaking or being forced to tilt due to external force. Optionally, the bracket structures of the installation shell 21 and the installation space are both made of insulating materials, such as plastic or rubber. In order to facilitate the processing and production of the installation shell 21, the bracket structures of the installation shell 21 and the installation space are an integrated structure.

[0056] In this embodiment, by arranging the terminal pressing plate 22 in the mounting shell 21, and using the terminal pressing plate 22 to cooperate with the first accommodating cavity 211 of the mounting shell 21, it is advantageous to firmly and stably mount the second terminal 25 in the mounting shell 21, thereby improving the service life of the adapter 2. It can be understood that in order to facilitate the connection and conduction between one end of the second terminal 25 and the first terminal 14 of the connecting seat 1 through the opening at one end of the mounting shell 21, the terminal pressing plate 22 is provided with a mounting hole 221 corresponding to each first accommodating cavity 211. When the second terminal 25 is installed in the first accommodating cavity 211, one end of the second terminal 25 can pass through the mounting hole 221 and be connected to the plug-in slot 142 of the first terminal 14.

[0057] It can be understood that in order to further achieve the limited installation of the plug slot 142, a first limit block 212 is protruding from the cavity wall of the end of the first accommodating cavity 211 away from the connecting seat 1, that is, a first limit block 212 is protruding from the cavity wall of the end of the first accommodating cavity 211 away from the terminal pressing plate 22, so that the second terminal 25 can be conveniently limited between the first limit block 212 and the terminal pressing plate 22. Of course, the end of the second terminal 25 adjacent to the first limit block 212 is provided with a terminal plug hole 252, so that the first limit block 212 is protruding around the cavity wall of the end of the first accommodating cavity 211, and a through-hole structure is formed corresponding to the terminal plug hole 252, so that the charging pin of the charging gun can be conveniently inserted into the terminal plug hole 252 through the through-hole structure.

[0058] In this embodiment, in order to facilitate the removal of the second terminal 25, the terminal pressing plate 22 and the mounting shell 21 are set to a detachable connection structure, such as a snap connection, plug-in fit, screw or pin connection, etc., which is not limited here. As an optional implementation scheme of this embodiment, the terminal pressing plate 22 and the bracket structure in the mounting shell 21 are connected by snap connection or screw connection.

[0059] In one embodiment, if Figure 4 and Figure 5 As shown, a first limit platform 213 is formed on the cavity wall of each first accommodating cavity 211 adjacent to one end of the terminal pressing plate 22, and a second limit platform 222 is protrudingly provided on the terminal pressing plate 22 around each mounting hole 221. A first boss 251 is protrudingly provided on the periphery of each second terminal 25. One end of each second terminal 25 is accommodated in a first accommodating cavity 211, and when the other end passes through the mounting hole 221, the first boss 251 is limited between the first limit platform 213 and the second limit platform 222.

[0060] It can be understood that a first limit platform 213 is formed on the cavity wall of the first accommodating cavity 211 adjacent to one end of the terminal pressing plate 22, and a first boss 251 is protruded on the periphery of the second terminal 25. In this way, when the second terminal 25 is installed in the first accommodating cavity 211, one end of the second terminal 25 with a terminal socket 252 is limitedly abutted against the first limit block 212, and the first boss 251 of the second terminal 25 is further limited between the first limit platform 213 and the terminal pressing plate 22, thereby achieving a stable installation of the second terminal 25.

[0061] In this embodiment, a second limiting platform 222 is provided on the terminal pressing plate 22 around each mounting hole 221, that is, the second limiting platform 222 is provided in a hollow columnar structure, and the second limiting platform 222 cooperates with the mounting hole 221 to form a cylindrical structure. When the second terminal 25 is installed in the first accommodating cavity 211, the first boss 251 of the second terminal 25 is limited between the first limiting platform 213 and the second limiting platform 222. In this arrangement, on the one hand, the second limiting platform 222 of the terminal pressing plate 22 cooperates with the first limiting platform 213 of the mounting shell 21 to realize the limited installation of the second terminal 25, and on the other hand, the second limiting platform 222 cooperates with the mounting hole 221 to form a cylindrical structure to protect the end of the second terminal 25 that cooperates with the plug-in slot 142 of the first terminal 14.

[0062] In one embodiment, if Figure 4 and Figure 5 As shown, the adapter 2 further includes a first sealing ring 23 sleeved on each second terminal 25, and the first sealing ring 23 is sandwiched between the first limiting platform 213 and the first boss 251. It can be understood that the provision of the first sealing ring 23 can prevent water or water vapor from entering the connection between the second terminal 25 and the first terminal 14 from the cavity wall of the first accommodating cavity 211 and the second terminal 25, causing the adapter charging socket 100 to malfunction.

[0063] In one embodiment, if Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the adapter seat 2 also includes a cover plate 24, which has a closed position covering the opening of the end of the mounting shell 21 facing away from the connecting seat 1, and an open position open relative to the opening of the end of the mounting shell 21 facing away from the connecting seat 1; between the closed position and the open position, one end of the cover plate 24 is rotatably connected to the mounting shell 21; in the closed position, the other end of the cover plate 24 is detachably connected to the mounting shell 21.

[0064] It can be understood that the cover plate 24 is arranged at the opening of the end of the mounting shell 21 facing away from the connecting socket 1. Such a configuration is beneficial for the cover plate 24 to protect the inside of the adapter socket 2 of the adapter charging socket 100 from falling into dust, debris, etc. when the adapter socket 2 is not connected to the charging gun, that is, when the adapter charging socket 100 is not in use. When the charging gun needs to be connected or the charging socket needs to be plugged in, the cover plate 24 is opened, and the charging pin of the charging gun can be inserted into the terminal jack 252 of the second terminal 25 of the adapter socket 2 to achieve charging conduction.

[0065] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in one embodiment, a rotating shaft 241 is provided at one end of the cover plate 24, and a groove 214 is recessed in the mounting shell 21 corresponding to the rotating shaft 241. A rotating shaft hole 215 matching the rotating shaft 241 is opened on the side wall of the groove 214, and the cover plate 24 is rotatably connected to the mounting shell 21 through the hole-axis cooperation of the rotating shaft 241 and the rotating shaft hole 215.

[0066] It can be understood that the mounting shell 21 is in the shape of a circular cylinder or a square cylinder, that is, the opening of the mounting shell 21 is circular or square. In order for the cover plate 24 to seal and protect the adapter 2, the shape and structure of the cover plate 24 match the opening shape of the mounting shell 21. Optionally, the cover plate 24 is arranged in a circular shape. A connecting portion is convexly provided on the periphery of the cover plate 24, and two rotating shafts 241 arranged in opposite directions are convexly provided in the length direction of the connecting portion. A mounting portion is convexly provided on the outer wall of the mounting shell 21 adjacent to the opening, and a groove 214 is concavely provided on the mounting portion for accommodating the connecting portion of the cover plate 24, and rotating shaft holes 215 are provided on opposite sides of the groove 214, so that the rotating shaft 241 of the connecting portion is penetrated in the rotating shaft hole 215 of the groove 214, so that the cover plate 24 is rotatably connected to the mounting shell 21 through the hole-axis matching of the rotating shaft 241 and the rotating shaft hole 215.

[0067] In this embodiment, in order to facilitate the cover plate 24 to cover or open the opening of the mounting shell 21, one end of the cover plate 24 facing away from the rotating shaft 241 is convexly provided with one of the buckle 216 and the buckle hole 242, and the side of the mounting shell 21 facing away from the groove 214 is provided with the other of the buckle 216 and the buckle hole 242. In the closed position, the other end of the cover plate 24 is detachably connected to the mounting shell 21 through the buckle fit of the buckle 216 and the buckle hole 242.

[0068] It can be understood that the periphery of the cover plate 24 is convexly provided with a buckle 216 away from the rotating shaft 241, and the outer wall of the mounting shell 21 is provided with a buckle hole 242 on the side facing away from the groove 214. When the cover plate 24 closes the opening of the mounting shell 21, the cover plate 24 is detachably connected to the mounting shell 21 through the buckle fit of the buckle 216 and the buckle hole 242. Of course, the buckle 216 can also be set on the mounting shell 21, and the buckle hole 242 is set on the cover plate 24, which is not limited here. In this embodiment, the structure of the buckle 216 and the buckle hole 242 can be any structure as long as it can realize the buckle connection between the cover plate 24 and the mounting shell 21, which is not limited here.

[0069] In one embodiment, if Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the connecting base 1 includes a fixed shell 11 and a buckle cover 12, wherein the fixed shell 11 is in the shape of a cylinder with openings at both ends, a plurality of second accommodating cavities 111 arranged at intervals are provided in the fixed shell 11, each first terminal 14 is accommodated and limited in a second accommodating cavity 111, and the fixed shell 11 is detachably connected to the mounting shell 21; the buckle cover 12 covers the opening at one end of the fixed shell 11 facing away from the mounting shell 21, the buckle cover 12 is detachably connected to the fixed shell 11, and the connecting base 1 is installed on the electric vehicle through the buckle cover 12.
