[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0026] like Figure 1-Figure 2 As shown, the present application provides a charging and discharging connector, including a charging and discharging component 1, the charging and discharging component 1 includes a charging seat 2, the charging seat 2 is arranged on a wall, and a connector 3 is installed on one side of the charging seat 2, the connector 3 is suitable for being electrically connected to the charging seat 2, thereby realizing the charging and discharging functions of an electric vehicle or other equipment, and a sealing rubber ring 5 is arranged between the connector 3 and the charging seat 2, the sealing rubber ring 5 can effectively prevent water and dust from entering the connector 3 and the charging seat 2, thereby protecting the electrical components of the electric bicycle from damage;

[0027] At the same time, in order to improve the stability and safety of the charging and discharging assembly 1, a locking structure 4 is designed between the connector 3 and the charging base 2. The locking structure 4 is used to ensure that the connection between the connector 3 and the charging base 2 is firm and prevent accidental falling off.

[0028] The charging base 2 is provided with a plurality of through threaded holes 21 around it. Bolts are arranged in the threaded holes 21 so that the charging base 2 can be stably mounted on the wall. At the same time, an interface 22 is provided at the center of the charging base 2, and the interface 22 is used for mounting the connector 3.

[0029] At the same time, guide grooves 23 are arranged on both sides of the interface 22, and springs 231 are arranged inside the guide grooves 23. At the same time, guide columns 31 are arranged on both sides of the connector 3. The length of the guide columns 31 is greater than the length of the connector 3, and the size of the guide columns 31 is adapted to the size of the guide grooves 23. When the connector 3 is installed, the guide columns 31 will be inserted into the guide grooves 23 before the connector 3, thereby playing a guiding role and ensuring that the connector 3 can be correctly aligned and inserted into the interface 22.

[0030] like Figure 3-Figure 6 As shown, two groups of locking structures 4 are provided, and the two groups of locking structures 4 are respectively provided at the top and the bottom of the interface 22, the locking structure 4 includes a ratchet plate 41, one end of the ratchet plate 41 is provided with a boss 42, and a slope 411 is provided at the connection between the ratchet plate 41 and the boss 42, and a clamping strip 32 is hinged at the top of the connector 3, the clamping strip 32 includes a locking end at the front and a pressing end at the rear, a rotating shaft is provided between the locking end and the pressing end, and a torsion spring is provided at the rotating shaft, so that the locking end is in a horizontal state under the action of the torsion spring, and when the pressing end is pressed, the locking end will tilt up;

[0031] At the same time, a notch 33 matching the slope of the inclined surface 411 is provided on one side of the locking end, and a through groove 321 is provided in the locking end, the size of the through groove 321 is adapted to the size of the boss 42, and a pawl 34 is provided at the bottom of the clamping strip 32, and the pawl 34 is engaged with the ratchet plate 41.

[0032] When the connector 3 needs to be installed on the charging base 2, the guide column 31 is first controlled to be installed into the guide groove 23, so that the position of the connector 3 matches that of the charging base 2. At the same time, as the connector 3 gradually goes deeper, the clamping strip 32 will contact the ratchet plate 41. Since a notch 33 is provided at the front end of the clamping strip 32, the clamping strip 32 can slide into the inside of the boss 42 through the cooperation of the notch 33 and the inclined surface 411, and then when the connector 3 is fully connected to the charging base 2, the clamping strip 32 is fully engaged with the ratchet plate 41.

[0033] Furthermore, since a spring 231 is provided in the guide groove 23, when the guide post 31 is inserted into the guide groove 23, the spring 231 is squeezed, and at this time, the spring 231 applies a reaction force to the guide post 31, so that the guide post 31 moves in a direction away from the charging stand 2, and since the pawl 34 and the ratchet plate 41 are meshed with each other at this time, the connection between the notch 33 and the boss 42, the pawl 34 and the ratchet plate 41 is tighter, so that the connector 3 will not accidentally detach from the charging stand 2, thereby ensuring the stability and reliability of the connection;

[0034] When it is necessary to separate the connector 3 from the charging base 2, it is only necessary to press the pressing ends of the two sets of snap-fit ​​strips 32 at the same time, so that the front end of the snap-fit ​​strips 32 is tilted and separated from the ratchet plate 41. At this time, the connector 3 can be popped outward under the action of the spring 231, thereby realizing the separation of the connector 3 from the charging base 2.

[0035] In summary, by setting up the locking structure 4, the device can effectively increase the stability between the connector 3 and the charging base 2, so that the connector 3 will not be easily separated from the charging base 2. At the same time, since the locking structure 4 is set into two groups, even if one of the groups is accidentally touched and opened, the other group can still keep the device locked, further improving the safety of the device.

[0036] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
