[0035] In order to solve the technical problems in the prior art, the present application provides a conversion switch, including a switch seat, a plurality of electrodes, a rotating shaft and a rotating electric key. Each of the electrodes includes a connecting portion and a fixing portion, the fixing portion is installed on a side surface of the switch seat, the connecting portion is provided with a protrusion, the protrusion matches the outer wall of the switch seat, and the connecting portion of each of the electrodes is electrically connected to one end of the battery pack. The rotating shaft is rotatably installed on the switch seat and connected to the rotating electric key. The rotating electric key is located on one side of the fixing portion of the electrode. When the rotating shaft rotates, the rotating electric key is switched to be connected with different electrodes to convert the output voltage of the battery pack, thereby realizing the output voltage gear conversion of the battery pack. The present application provides a protrusion matching with the switch seat on each electrode, so that the stability of the electrode and the switch seat is better. During processing, each electrode can be installed on the switch seat, and the surface of the protrusion can be processed as a whole to achieve the same height and consistent surface roughness of each electrode surface, which is more convenient to process and improves the consistency of each electrode. Therefore, the conversion switch can be applied to multi-voltage output conversion in larger current scenarios.

[0036] The implementation structure of the switch in one embodiment is described in detail below in conjunction with the accompanying drawings. It should be understood that the structures shown in the accompanying drawings and the following description are examples and are not intended to limit the scope of protection of this application.

[0037] like Figures 1 to 4 As shown, in one embodiment of the present application, the conversion switch includes a switch seat 5, a plurality of electrodes, a rotating shaft 6 and a rotary switch 7. In this embodiment, four electrodes are provided: a first electrode 1, a second electrode 2, a third electrode 3 and a fourth electrode 4. Each electrode is implemented by a connecting copper piece, but the present application is not limited thereto. Each of the electrodes includes a connecting portion and a fixing portion, each of the fixing portions is in an arc shape, the fixing portion is mounted on a side surface of the switch seat 5 by a screw, the connecting portion extends outward from the switch seat 5, and the connecting portion is provided with a protrusion (only the protrusion 11 of the first electrode 1 is shown by way of example in the figure, and it can be seen from the figure that each electrode is provided with a protrusion). The protrusion matches the outer wall of the switch seat 5. In this embodiment, the switch seat 5 is cylindrical, and the side surface of the protrusion of the electrode facing the switch seat 5 is an arc surface matching the outer wall of the switch seat 5. Therefore, by providing a protrusion matched with the switch seat 5 on each electrode, the stability of the electrode and the switch seat 5 is improved. During processing, the fixing parts of the four electrodes can be installed on the surface of the switch seat 5 by screws, and then the surface of the protrusion is processed as a whole to achieve the same height and consistent surface roughness of each electrode surface, which is more convenient to process and improves the consistency of each electrode. The conversion switch can be used in an automobile emergency starting power supply device, and can also be used in other power supply devices that require conversion between multiple output gears.

[0038] The rotating shaft 6 is rotatably mounted on the switch seat 5 and connected to the rotating electric key 7. A rotating groove is provided at the center of the switch seat 5, and the rotating shaft 6 is installed in the rotating groove, and the two ends of the rotating shaft 6 protrude from the rotating groove respectively. The part of the upper end of the rotating shaft 6 that extends out of the rotating groove can be matched with a knob (not shown in the figure) to facilitate manual operation by the user. The rotating electric key 7 is located on one side of the fixed part of the electrode. When the rotating shaft 6 rotates, the rotating electric key 7 is switched to be connected with different electrodes, and the output voltage of the battery pack is converted, thereby realizing the output voltage gear conversion of the battery pack. Therefore, by adjusting the rotating shaft 6, the conversion switch can realize multi-voltage gear output conversion in a larger current scenario, for example, it can meet the multi-voltage gear (such as 12V and 24V) output switching of a large current scenario of more than 1500A. The connecting part of each of the electrodes is electrically connected to one end of the battery pack. Figure 5 The structure of connecting each electrode to the battery pack is shown as an example, wherein each arc corresponds to an electrode. The battery pack includes two 12V batteries. When battery 1 and battery 2 form a series circuit through electrodes and a rotating switch 7, a 24V voltage is output. When battery 1 and battery 2 form a parallel circuit through electrodes and a rotating switch 7, a 12V voltage is output.

[0039] In this embodiment, two rotary keys 7 are provided, and the two rotary keys 7 are arranged opposite to each other. The surface of the rotary key 7 on one side opposite to the fixed part of the electrode is in an arc shape, which can increase the contact area between the rotary key 7 and the fixed part of the electrode, so that the rotary key 7 has higher stability and can carry a larger current when the rotary key 7 is connected to the electrode. The conversion switch also includes an elastic member support 8, and the elastic member support 8 is located on the side of the rotary key 7 away from the electrode, and the elastic member support 8 is connected to the lower end of the rotating shaft 6 by a screw, and at least one elastic member 10 is provided between the elastic member support 8 and each rotary key 7. In this embodiment, two elastic members 10 are provided between the elastic member support 8 and each rotary key 7, and the two elastic members 10 are arranged along the length direction of the rotary key 7. As shown Figure 4As shown, the surface of one side of the rotary key 7 facing the elastic member support 8 is in an arc shape, and the length direction of the rotary key 7 is the extension direction of the arc. The two elastic members 10 are provided at both ends of the arc, and a raised stopper 71 is provided between the two elastic members 10 to limit the positions of the two elastic members 10. Since an elastic member 10 is provided at each end of each rotary key 7, it can be ensured that the forces at both ends of the rotary key 7 are uniform, and the contact surface between the rotary key 7 and the fixed part of the electrode is uniformly forced. In this embodiment, the elastic member 10 is a compression spring, but the present application is not limited thereto. In other alternative embodiments, the elastic member 10 may also be a spring or other elastic structure, which also falls within the protection scope of the present application.

[0040] like Figure 3 As shown, in this embodiment, the rotating shaft 6 is provided with a sensing part 61, and the switch seat 5 is provided with at least one signal switch 9. In this embodiment, two signal switches 9 are provided, but the present application is not limited thereto, and the number of signal switches 9 can be selected and set as needed. When the rotating shaft 6 rotates, the relative position of the sensing part 61 and the signal switch 9 is changed to change the output signal of the signal switch 9, and the signal receiving end of the signal switch 9 can determine the output voltage gear corresponding to the current conversion switch according to the change of the output signal. In this embodiment, the signal switch 9 is arranged on the side of the switch seat 5 away from the fixed part of the electrode, and the sensing part 61 is a protruding structure arranged on the side of the rotating shaft 6. The signal switch 9 can be implemented, for example, by a micro switch, which is a contact mechanism with a small contact interval and a quick-action mechanism, and performs a switching action with a specified stroke and a specified force.

For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, which should be deemed to fall within the scope of protection of the present application.
