[0020] To make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe the specific embodiments of the present application in detail with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0021] Today, with the increasing popularity of two-wheeled electric vehicles, the charging connector, as a key component in the charging process of two-wheeled electric vehicles, its performance and reliability are crucial. With the rapid development of the two-wheeled electric vehicle market, users have higher requirements for the convenience and safety of charging. However, there are many problems in the actual application of existing ordinary two-wheeled electric vehicle charging connectors.

[0022] Traditional charging connectors usually have a relatively simple structure and lack an effective locking mechanism. During the charging process, they are easily affected by external factors, such as vehicle movement, cable pulling, etc., resulting in the connector becoming loose or even falling off, affecting the normal progress of charging. In severe cases, it may even cause circuit failures and safety hazards. In addition, since two-wheeled electric vehicles will face various different environmental conditions during use, such as wind, rain, dust, etc., the existing charging connectors often lack performance in dust and water protection. This makes the inside of the connector easily eroded, reducing the service life and charging efficiency of the connector.

[0023] The snap - type connector of the present application has a simple and reliable structure. Through the cooperation between the buckle block on the inner frame and the buckle groove on the hanging buckle, the initial snap - in connection between the female seat and the plug is realized, ensuring the stability of the connection. Through the pivotal connection between the pivotal part and the mounting seat, the flexible rotation of the hanging buckle is realized, facilitating the snap - in and unlocking operations. Through the insertion and cooperation between the cooperation part and the push block, the effective pushing control of the push block on the hanging buckle is realized, thereby realizing the rotation of the hanging buckle. Through the connection of the spring between the cooperation part and the push block, the resilience is provided for the push block during the unlocking operation, making the operation more convenient.

[0024] The specific structure of the snap - type connector will be introduced in detail below.

[0025] As Figures 1 to 3 shown, an embodiment provides a snap - type connector, including: a female seat 100, a plug 200, and a locking mechanism 300.

[0026] Among them, the female seat 100 includes: an inner frame 110 and a buckle block 120 arranged on the inner frame 110; the plug 200 includes: an outer mold body 210 and a mounting seat 220 arranged on the outer mold body 210, and an activity groove 222 is formed by recessing outward into the outer mold body 210 on the mounting seat 220; the locking mechanism 300 includes: a hanging buckle 310, a push block 320, and a spring 330. The hanging buckle 310 includes a snap - in part 311, a pivotal part 312, and a cooperation part 313 connected in sequence. The pivotal part 312 is pivotally connected to the mounting seat 220. A buckle groove 3111 for cooperating with the buckle block 120 is arranged on the snap - in part 311. The cooperation part 313 is in insertion and cooperation with the push block 320. The spring 330 is connected between the cooperation part 313 and the push block 320; the cooperation part 313 is configured to be able to move towards the activity groove 222 under the action of the push block 320.

[0027] It should be noted that the snap - in part 311, the pivotal part 312, and the cooperation part 313 are of an integrally formed structure.

[0028] When the snap - type connector in the embodiment of the present application is in use, the user holds the plug 200 close to the female seat 100 and inserts the plug 200 into the female seat 100 after alignment. Initially, the bottom of the push block 320 abuts against the bottom wall of the mounting seat 220. Push the push block 320 towards the female seat 100. The push block 320 moves relative to the cooperation part 313, and the spring 330 is compressed. At this time, the push block 320 is located above the activity groove 222. Press the push block 320. Driven by the push block 320, the cooperation part 313 moves into the activity groove 222, and the snap - in part 311 tilts upwards, so that the buckle groove 3111 of the snap - in part 311 can be buckled with the buckle block 120. Subsequently, under the action of the spring 330, the push block 320 resets to the initial position.

[0029] As Figures 1 to 3As shown, in some embodiments, a lifting block 130 is provided on the inner frame 110, and the buckle block 120 is provided on the lifting block 130. With this arrangement, when the plug 200 is inserted into the female socket 100, the buckle block 120 and the hook 310 are at the same horizontal position, facilitating the buckle connection. Furthermore, when the hook 310 is buckled with the buckle block 120, the buckle portion 311 of the hook 310 abuts against the lifting block 130.

[0030] like Figures 1 to 3 As shown, in some embodiments, the buckle block 120 has an inclined surface 121 that slopes downward and outward from top to bottom on one end facing the plug 200. With this arrangement, when the plug 200 is inserted into the female socket 100, the buckle portion 311 slides with the inclined surface 121, causing the buckle portion 311 to tilt upward, thereby facilitating the buckle 310 to buckle.

[0031] like Figures 1 to 3 As shown, in some embodiments, the locking mechanism 300 further includes a pin 340 pivotally connected to the pivotal portion 312; the mounting base 220 has a through-hole 221 extending along the width of the mounting base 220, and the pin 340 is disposed in the through-hole 221. With this arrangement, the hook 310 is mounted on the mounting base 220 via the pin 340, allowing the pivotal portion 312 of the hook 310 to rotate about the axis of the pin 340, thereby facilitating the hook 310's fastening.

[0032] like Figures 1 to 3 As shown, in some embodiments, the push block 320 has a cavity 321 and a first slot 322 and a second slot 323 connected to the cavity 321, the mating portion 313 includes a first plug block 3131 and a second plug block 3132, at least a portion of the mating portion 313 is inserted into the cavity 321, the first plug block 3131 is inserted into the first slot 322, and the second plug block 3132 is inserted into the second slot 323.

[0033] The first inserting block 3131 is inserted into the first slot 322 , and the second inserting block 3132 is inserted into the second slot 323 , which can improve the connection stability between the pushing block 320 and the hanging buckle 310 and prevent the pushing block 320 and the hanging buckle 310 from shaking when they are matched.

[0034] like Figures 1 to 3 As shown, in some embodiments, the mating portion 313 has a mounting hole 3133, and a mounting post 324 is provided on the inner surface of the cavity 321. One end of the spring 330 is located in the mounting hole 3133, and the other end of the spring 330 is sleeved on the mounting post 324. This arrangement can improve the connection stability between the spring 330, the hook 310, and the push block 320.

[0035] like Figures 1 to 3As shown, in some embodiments, abutting blocks 325 are provided at opposite ends of the pushing block 320, and guiding grooves 223 are formed on the inner surfaces of opposite ends of the mounting base 220, and the abutting blocks are located in the guiding grooves.

[0036] For example, when the pushing block 320 is in the initial position, under the action of the spring 330, the abutting block abuts against an inner surface of the guiding groove, thereby being able to prevent the pushing block 320 from detaching from the mounting base 220.
