Description

Technical Field

[0001] This utility model relates to the field of electronic lock technology, and in particular to a switch device and a charging gun. Background Technology

[0002] With the development of science and technology, electronic locks have gradually become widespread in people's lives. In the current field of electronic lock technology, the extension and retraction of the bolt are generally achieved by the forward and reverse rotation of a motor, thus opening and closing doors, windows, cabinets, and charging guns. For example, when charging an electric vehicle, the charging gun needs to be locked. Therefore, it is necessary to lock and control the charging gun of new energy electric vehicles to prevent accidental insertion or removal under load, and to ensure consistency between the transmission mechanism and the signal switch trigger position.

[0003] Especially with the development of new energy vehicles, most of them now rely on charging, inevitably involving the use of charging guns. The use of charging guns involves unlocking and unlocking the vehicle. Currently, the locking button and tactile switch on electronic locks are designed independently, occupying a relatively large area, requiring more design space during the electronic lock design process. This results in charging guns being bulky, heavy, and difficult to operate. Utility Model Content

[0026] This utility model provides a switch device 01, including: a button 13, which includes: a pressing part 131 disposed at one end of the button 13; and a connecting part 133 disposed at the other end of the button 13. It should be noted that the specific shape of the button 13 is not limited in this application; it can be square, cylindrical, prismatic, spherical, etc. Meanwhile, the connecting part 133 and the pressing part 131 are fixedly connected.

For example, in a preferred embodiment of this application, the connecting part 133 and the pressing part 131 are integrally molded, simply being one end and the other end of the button 13. The pressing part 131 is used for human-computer interaction; for example, a user presses the button using the pressing part 131. The connecting part 133 is used to connect external components. In this embodiment... Switch 15 is located below and to the side of button 13; switch 15 and connecting part 133 are fixedly connected. This fixed connection is a general concept and can be one or a combination of several of the following: integral molding, welding, threaded connection, riveting, interference fit, and snap-fit. Elastic element 17 is located below button 13, specifically directly below connecting part 133; under the action of elastic element 17 or external force, button 13 is displaced, causing the position of switch 15 to change, thereby achieving unlocking and locking.

[0027] The beneficial effects of this application are as follows: In this application, the elastic element 17 is disposed below the button 13, and the switch 15 is disposed to the side and below the button, which saves space and makes the structure of the switch device 01 more compact.

[0028] In another embodiment of this application, the button 13 includes: a columnar button body 135, the button body 135 including: a top surface 131 disposed at one end of the button 13; a bottom surface 133; the top surface 131 and the bottom surface 133 are disposed opposite each other, the bottom surface 133 is disposed at the other end of the button 13; an elastic element 17 is disposed below the bottom surface 133 and abuts against the bottom surface 133; the switch 15 is fixedly connected to the bottom surface 133 and extends outward from the surface of the bottom surface 133; wherein, the elastic element 17 is disposed on the side of the switch 15. The elastic element 17 can be a spring, torsion spring, rubber component, silicone component, or other elastic element; in a preferred embodiment of this application, a spring can be selected. Furthermore, the switch device 01 also includes: a circuit board 19; the elastic element 17 and the switch 15 are both disposed on the circuit board. The elastic element 17 is installed between the circuit board 19 and the bottom surface 133, and compresses and reciprocates as the distance between the bottom surface 133 and the circuit board 19 changes, thereby causing the switch 15 connected to the bottom surface 133 to move. In a preferred embodiment of this application, the switch device 01 further includes a waterproof sleeve 181, which is disposed around the button body 135 to prevent water or dust from entering the switch device 01 and damaging its performance.

[0029] The switching device 01 further includes: a first terminal 12 and a second terminal 14, the second terminal 14 being spaced apart from the first terminal 12; both the first terminal 12 and the second terminal 14 are mounted on the circuit board 19 and electrically connected to the circuit board 19; during the displacement of the switch 15, when it moves to the first position, it contacts the first terminal 12; when it moves to the second position, it contacts the second terminal 14. The switching device 01 also includes a resistor 16; the resistor 16 is mounted on the circuit board 19 and electrically connected to the circuit board 19.

[0030] The switching device 01 further includes a housing 18, which is a hollow cavity structure with an opening. The elastic element 17, the switch 15, the circuit board 19, the first terminal 12, and the second terminal 14 are all installed within the housing 18.

[0031] In some embodiments of this application, the switching device 01 further includes a baffle 11 disposed below the circuit board 19 and abutting against the lower sidewall of the housing 18. The switching device 01 also includes a pin 10 electrically connected to the circuit board 19.

[0032] Please see Figure 4 and Figure 5 ,in Figure 4 This is a schematic diagram of the disassembly structure of a charging gun provided in this application; Figure 5 This is a schematic diagram of the cross-sectional structure of another charging gun provided in this application.

The latch 041 is located at one end of the transmission device 04, and the trigger 043 is located at the other end. The rotating shaft 042 is located in the middle of the transmission device 04, and is used to rotate the latch 041. When the latch 041 rotates, the latch at one end rises, and correspondingly, the trigger 043 at the other end falls. The trigger 043 is connected to the switching device 01, and transmission occurs between the two.

[0035] The beneficial effects of this application are as follows: In this application, the elastic element 17 is disposed below the button 13, and the switch 15 is disposed to the lower side of the button, saving space and making the structure of the switch device 01 more compact. Furthermore, this makes the structure of the charging gun 001 more compact and its layout more reasonable.

[0036] It should also be noted that in this application, the switch 15 inside the switching device 01, through the elastic element 17 (preferably a spring in this application), not only enables the switching device 01 itself to open and close, but also provides elastic force for the mechanical transmission between the switching device 01 and the transmission device 04. Therefore, in this application, no additional elastic element is needed to achieve the transmission between the switching device 01 and the transmission device 04. Furthermore, the function of two or more elastic elements is accomplished under the action of one elastic element, saving space and making the structure of the switching device 01 more compact. Consequently, the structure of the charging gun 001 is more compact and the layout is more reasonable.
