[0028] A driving power supply protection device includes a mounting shell 1 arranged on a driving power supply, a mounting cavity being provided in the mounting shell 1, a connecting portion 3 for connecting an electrical connection pin 2 being rotatably provided in the mounting cavity, a toggle switch 4 being connected to the connecting portion 3, an opening 5 from which one end of the power connection pin 2 extends out being provided on the mounting shell 1, a stopper being provided on the mounting shell 1, and when the stopper acts on the toggle switch 4, the electrical connection pin 2 is limited in the mounting cavity, and when the stopper leaves the toggle switch 4, the toggle switch 4, under the action of an external force, links the electrical connection pin 2 through the connecting portion 3 to extend out of the opening 5.

[0029] Furthermore, the stopper includes a fixed shaft 61 arranged in the mounting shell 1 and a rotating member 62 rotatably arranged on the fixed shaft 61. A movable hole 63 is opened on the mounting shell 1. One end of the rotating member 62 extends out of the mounting cavity through the movable hole 63, and the other end is hooked on the toggle switch 4. The rotating member 62 is toggled to make the other end of the rotating member 62 leave the toggle switch 4.

[0030] Furthermore, a turntable 7 is provided on the connecting portion 3 , and first display gear positions 72 corresponding to the electrical connection pins 2 are provided on the circumference of the turntable 7 .

[0031] Furthermore, the mounting shell 1 is provided with a window 71 through which a portion of the turntable 7 can be exposed.

[0032] Furthermore, a display panel 8 is connected to one side of the turntable 7 , and a through hole 80 for rotationally engaging the display panel 8 is provided on the mounting shell 1 , and a second display gear 81 is provided on the display panel 8 .

[0033] Furthermore, anti-slip grooves are provided on the circumference of the turntable 7 .

[0034] Furthermore, a movable slot 9 for the toggle switch 4 to move is provided on the mounting shell 1 .

[0035] The working principle of this utility model is:

[0036] Use scenario 1: When the driver is in the transport state, such as Figure 1-3 As shown, one end of the stopper is hooked on the toggle switch 4. At this time, even during transportation, when the driving power supply is subjected to external forces such as vibration and impact, since the other end of the stopper is hooked on the toggle switch 4, the toggle switch 4 is in a limited state, that is, the toggle switch 4 cannot drive the connecting part 3 to rotate under the action of external force, so that the electrical connecting pin 2 connected to the connecting part 3 is always located in the installation cavity, effectively preventing the electrical connecting pin 2 from extending out of the opening 5 and causing extrusion and deformation.

[0037] Use scenario 2: When a driving power supply is required, such as Figure 4-6 As shown, press one end of the stopper downward to release the connection between the other end of the stopper and the toggle switch 4. At this time, manually toggling the toggle switch 4 can drive the connecting part 3 to rotate, so that one end of the electrical connecting pin 2 on the connecting part 3 extends out of the opening 5, and the electrical connecting pin 2 can be electrically connected to the electrical appliance for use.

[0038] As embodiment 1, the stopper can be realized by selecting a fixed shaft 61 and a rotating member 62 structure in combination; during transportation, the other end of the rotating member 62 is hooked on the toggle switch 4, so that the toggle switch 4 is in a limited state; when the driving power supply is needed, one end of the rotating member 62 is pressed downward, and the rotating member 62 rotates around the fixed shaft 61 so that the other end of the rotating member 62 leaves the toggle switch 4, then when the toggle switch 4 is toggled, it can be moved in the movable groove 9, and then the electrical connection foot 2 can be driven to extend out of the opening 5.

[0039] On the basis of the above technical solution, a turntable 7 is provided at the end of the connecting portion 3. The present application provides a first display gear 72 on the circumference of the turntable 7. When there are three first display gears 72, they can be indicated by marking ①②③. Each first display gear 72 corresponds to an electrical connection pin 2. When the current electrical connection pin 2 extends out of the opening 5, the first display gear 72 corresponding to the electrical connection pin 2 is exposed on the window 71, making it convenient for the user to select the corresponding electrical connection pin 2 according to needs. On this basis, in order to facilitate the user to rotate the turntable 7, the present application provides anti-slip grooves on the circumference of the turntable 7.

[0040] On the basis of the above technical solution, the present application also provides a display panel 8 on one side of the turntable 7, and a second display gear 81 corresponding to the first display gear 72 is provided on the display panel 8. The principle of the second display gear 81 is the same as that of the first display gear 72, that is, there are display gears at the bottom and side of the driving power supply, which is convenient for customers to use.

[0041] In order to solve the problem that the electrical connecting pin may be deformed during transportation, this application provides a stopper on the mounting shell, and utilizes the stopper to act on the toggle switch to limit the toggle switch. Then, the toggle switch will not be linked to the connecting part even under the action of external force, thereby ultimately preventing the electrical connecting pin from extending out of the opening, effectively preventing the electrical connecting pin from being squeezed and deformed, and thus protecting the product.

[0042] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the present invention as defined in the claims. Therefore, the detailed description of the disclosed embodiments is intended to illustrate rather than limit the present invention, which shall be defined by the claims.
