Description

Technical Field

[0001] The utility model relates to the technical field of electric bicycles, in particular to an electric bicycle charging socket. Background Art

[0002] Electric bicycles are all equipped with a socket, which is plugged into one end of the charger when charging. Conventional sockets, such as the one disclosed in the authorization announcement number CN201149923Y, include a socket body and a cover. The cover is hinged to the socket body by a pin, and the cover can be flipped up when in use. There is also a spring on the pin. When the charger is pulled out, the cover automatically flips down and returns to its original position under the elastic force of the spring. For electric vehicles that charge quickly, the socket mainly changes the structure of the middle jack, and the socket jack is used in conjunction with a charging gun that can be charged quickly. For example, the appearance patent disclosed in the authorization announcement number CN303133688S discloses an electric vehicle fast charging socket, which also uses a cover hinged to the socket body. However, for a charging gun that charges quickly, due to the large charging current, the thick cable, and the certain weight of the charging gun, if the conventional charging operation is followed, one hand needs to pry the socket cover upwards, and the other hand needs to hold the charging gun and insert it into the socket, which is obviously not as convenient as the conventional electric vehicle charger.

[0014] Beneficial effects of the utility model:

[0015] When charging an electric bicycle equipped with the charging socket, the user flips the cover upwards. After the cover is flipped into place, the second limit part cooperates with the first limit part so that the cover will not automatically reset downwards even if the user lets go of the cover. Then the user holds the charging gun and inserts it into the charging port of the charging socket. After charging is completed, the user pulls out the charging gun and slightly applies downward force to the cover with the hand to release the limiting effect of the second limit part. Then the cover resets under the elastic force of the torsion spring to cover the charging port. When operating the charging gun, the cover is in an upwardly opened state without the need to hold it with the hand, which improves the convenience of operation. When not charging, the cover covers the charging port to achieve the purpose of waterproofing and dustproofing. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0023] Embodiments of the present utility model:

[0024] like Figure 1-Figure 5 As shown, the electric vehicle charging socket includes a seat body 1 and a cover 2. The seat body 1 is provided with a charging interface 4, and the charging interface 4 is for inserting a charging gun. The rear end of the charging interface 4 is used to connect a cable and connect to the battery of the electric vehicle. The cover 2 is hinged to the seat body 1 through an axis, and a torsion spring 3 is sleeved on the axis. The cover 2 is flipped up to expose the charging interface 4, and flipped down to cover the charging interface 4. When charging, flip the cover 2 up.

[0025] A first limiting portion 221 is provided at the upper end of the cover 2, and a second limiting portion 12 is provided on the base 1. When the cover 2 is turned up to the right position, the first limiting portion 221 cooperates with the second limiting portion 12 to maintain the turned-up state of the cover 2. Both the first limiting portion 221 and the second limiting portion 12 are convex strip-shaped and have an arc surface structure. The two can cooperate in a limited manner and can be separated under the action of external force.

[0026] The cover 2 comprises a cover plate, a hinged portion 21 on the upper end of the cover plate, and a torsion spring matching portion 22 . There are two hinged portions 21 , and the shaft passes through the two hinged portions 21 .

[0027] The torsion spring fitting part 22 includes a column part, the shaft passes through the column part, and there is a groove between the column part and the upper end of the cover plate, the groove forms the torsion spring fitting part 22, and the torsion spring fitting part 22 is located in the middle position of the two hinge parts 21, and the torsion spring fitting part 22 is used for abutting and fitting with the torsion spring 3.

[0028] The first limiting part 221 is provided on the outer circumference of the column part, and the first limiting part 221 is semi-cylindrical. The torsion spring 3 is a double torsion spring, and the central part 31 of the double torsion spring cooperates with the torsion spring matching part 22, and the hooks 32 at both ends of the double torsion spring cooperate with the seat body 1; the seat body 1 is provided with a plug hole for the hooks 32 at both ends of the double torsion spring to be inserted. When the cover 2 is flipped upward, when the first limiting part 221 contacts the second limiting part 12, there is a certain resistance between the two. With a little force, the resistance can be overcome and the cover 2 can be flipped upward. After the first limiting part 221 passes over the convex point of the second limiting part 12, you can let go. At this time, the second limiting part 12 blocks the first limiting part 221, which can prevent the cover 2 from resetting downward under the action of the torsion spring.

[0029] The electric vehicle charging socket also includes a mounting plate (not shown), which is connected to the seat body 1 by screws. The seat body 1 is provided with screw holes 11 that pass through the front and back. The screw holes are countersunk structures so that the screws are not exposed. The mounting plate is made of thin iron sheets.

[0030] During installation and use, an installation hole is opened on the outer shell of the electric bicycle, and the socket is inserted into the outer shell. The above-mentioned mounting plate is located inside the outer shell of the electric bicycle. Since the mounting plate has a certain deformation ability, the mounting plate can fit well on the inner side of the outer shell of the electric bicycle during installation, and then be fixed together with the seat body and the outer shell by screws or bolts.

[0031] When charging an electric bicycle equipped with the charging socket, the user flips the cover 2 upwards, and after flipping into place, the second limit portion 12 blocks the first limit portion 221. After letting go, the cover 2 will not return downward under the action of the torsion spring, and then the charging gun is held and inserted into the charging socket 4. After charging is completed, the charging gun is pulled out, and the cover 2 is slightly forced by hand to release the limiting effect of the second limit portion 12, and then it is reset under the elastic force of the torsion spring to cover the charging interface 4.

[0032] Furthermore, in order to improve the waterproof effect, an O-ring 5 is embedded inside the cover 2 , and after the cover 2 is closed, the O-ring 5 is attached to the end face of the charging port 4 .
