Description

Technical Field

[0001] The utility model relates to the technical field of charging guns, in particular to a control switch mounting structure for a charging gun and an AC charging gun. Background Art

[0002] New energy charging guns are used to charge new energy electric vehicles and provide energy for them. AC charging guns generally use a mechanical locking structure to achieve a secure fit between the charging gun and the charging base. When charging an electric vehicle, the charging gun is inserted into the charging socket of the electric vehicle to complete the matching, and a mechanical button is used to press the micro switch to form a closed circuit for charging. In traditional AC charging guns, the charging gun cover is often assembled with multiple sets of screws and the charging gun housing. The assembly takes a long time and is costly. The micro switch in the charging gun needs to be coordinated with the hook assembly to form a linkage. However, when the micro switch is assembled without screws, it is often positioned with the help of holes or pins. It is easy to misalign and has poor stability, which affects the safety performance of the charging gun. In addition, the installation process is complicated and requires high technical skills of the installer, which increases material and labor costs. Utility Model Content

[0003] In response to the shortcomings in the existing technology, the purpose of the present utility model is to provide a control switch installation structure for a charging gun and an AC charging gun, which can effectively solve the technical problems of the existing charging gun micro-control switch assembly process being complex, time-consuming, costly, and easy to dislocate.

[0004] In order to achieve the above technical objectives, the present invention adopts the following technical solutions:

[0005] One technical solution of the present invention provides a control switch mounting structure for a charging gun, comprising a control switch and a hook member disposed between a charging gun housing and an upper cover of the charging gun. The charging gun housing and the upper cover of the charging gun are fixedly connected by a buckle.

[0006] The upper surface of the charging gun housing is provided with a mounting platform, on which a switch limiter, a rotating shaft support, and a spring slot are provided. A square slot is provided in the switch limiter, and at least two U-shaped slots communicating with the square slot are symmetrically provided on the side wall of the switch limiter. The control switch is inserted into the square slot and the U-shaped slot, and a spring is vertically installed in the spring slot.

[0007] The hook member includes a hook portion, a hinge portion, and a pressing portion from front to back. The hook portion abuts against the top of the control switch, and the front end of the hook portion extends out of the charging gun housing. The hinge portion is hinged to the shaft support, and the pressing portion abuts against the top of the spring.

[0008] The upper cover of the charging gun is provided with a button mounting hole, a switch button is passed through the button mounting hole, and the switch button is connected to the pressing portion.

[0009] During use, the operator presses the switch button downward to control the pressing portion at the rear end of the hook member to compress the spring downward. Under the pivoting action of the hinged connection, the hook member lifts upward, separating from the control switch and sending back a signal to activate the power-off mode. After the hook member engages with the external charging dock socket, the switch button is released, and the charging gun head connects to the charging dock socket. The spring force lifts the pressing portion upward, and at the same time, the hook member moves downward to abut the control switch and send back a signal. The detection unit forms a parallel circuit, and charging begins. After charging is completed, press the switch button downward to lift the hook member and remove the charging gun head from the charging dock socket.

[0010] Furthermore, the mounting platform is provided with a number of upwardly protruding hidden buckles, and the lower side surface of the charging gun cover is provided with a number of hanging slots. The hanging slots correspond one-to-one to the hidden buckles and are connected by snaps, thereby realizing a quick connection between the charging gun cover and the charging gun shell. The snap connection has good stability and does not require fixing with screws, saving installation time and cost, and preventing the screws from rusting.

[0011] Furthermore, two rows of positioning slots are symmetrically provided on the mounting platform, and two rows of positioning strips are provided on the upper cover of the charging gun. The positioning strips are inserted into the positioning slots one by one, which plays a role in locating the connection position when the upper cover of the charging gun and the charging gun shell are quickly connected, and improves the connection stability to prevent the upper cover of the charging gun from loosening.

[0012] Furthermore, at least two vertical first axial hole grooves are provided on one side of the mounting platform close to the hook portion, and a first plug-in shaft matching the shape of the first axial hole groove is provided on the upper cover of the charging gun. The first plug-in shaft is inserted into the first axial hole groove, and plays a limiting and connecting role when the upper cover of the charging gun is snap-connected with the charging gun housing.

[0013] Furthermore, at least two vertical second plug shafts are provided on one side of the mounting platform close to the pressing portion, and a second shaft hole groove matching the shape of the second plug shaft is provided on the upper cover of the charging gun. The second plug shaft is inserted into the second shaft hole groove, and plays a limiting and connecting role when the upper cover of the charging gun is snap-connected with the charging gun housing.

[0014] Furthermore, a limit post is vertically arranged in the spring slot, and the spring is sleeved on the outside of the limit post and accommodated in the spring slot. The limit post can ensure that the spring deforms in the vertical direction and can also play a certain limiting role to prevent the spring from being over-compressed.

[0015] Furthermore, at least two snap connectors are symmetrically provided at the bottom of the switch button. When the switch button abuts against the pressing portion, the snap connectors are snapped into engagement with the edge bottom surfaces on both sides of the pressing portion, thereby achieving a fitting connection between the two. By pressing the switch button, the pressing portion can be driven to achieve synchronous movement.

[0016] Furthermore, at least two pin holes are provided on the pressing portion, and a vertical pin shaft matching the shape of the pin hole is provided at the bottom of the switch button. The pin shaft is inserted into the pin hole to define the connection position between the switch button and the pressing portion.

[0017] Furthermore, the hinged portion and the shaft support are hingedly connected by passing a rotating shaft through the shaft support, the shaft support is fixed on the mounting platform, and the hook member rotates in the shaft support.

[0018] The present utility model also provides an AC charging gun, including a charging gun housing, a charging gun cover, a charging gun head and a charging gun tail. The control switch installation structure for the charging gun as described in any of the above schemes is adopted, and the control switch, the hook part and the switch button are installed between the charging gun housing and the charging gun cover.

[0019] The utility model has the following beneficial effects:

[0020] The control switch mounting structure for the charging gun provided by the utility model can quickly install the control switch in the charging gun housing, and is not easy to be misplaced. The upper cover of the charging gun and the charging gun housing can be quickly fixed by a snap connection. The assembly is simple and time-saving, which can save installation costs and material costs. The assembly is stable and not easy to loosen. The charging gun using this control switch mounting structure is simple to assemble, which extends the service life of the charging gun and improves safety performance.
