Existing dual-power conversion mechanisms are mostly complex in structure, requiring numerous parts, and sometimes even two sets of operating mechanisms to achieve dual-power conversion. Furthermore, existing dual-power conversion mechanisms occupy a large space, have complex inter-part relationships, and long dimensional chains, which can easily lead to large cumulative tolerances, thus affecting the structural fit and operational reliability.

[0028] A dual power supply conversion mechanism, the structural schematic diagram of which is shown below. Figure 1 , Figure 2 As shown, it includes a power shaft 101, a first bracket 2, a second bracket 6, a locking shaft 4, an output component 5, a drive shaft 7, and a drive component 8. The first bracket is rotatably mounted on the power shaft and has a first bracket locking shaft track groove 202 and a first bracket drive shaft track groove 203. The drive component is fixedly mounted on the power shaft and has a drive component drive shaft track groove 803 and an unlocking rod 801. The second bracket is fixedly mounted on the first bracket and has a second bracket locking shaft track groove 601 and a second bracket drive shaft track groove 603. Both the first bracket locking shaft track groove and the second bracket locking shaft track groove are arc-shaped structures. The first bracket locking shaft track groove and the second bracket locking shaft track groove are respectively provided with a middle groove and an end groove. The output component is rotatably mounted on the power shaft and the output shaft 505 of the output component is rotatably connected to the second bracket. The output component is provided with a drive shaft clearance hole 504 and a locking shaft clearance hole 502. The locking shaft passes through the second bracket locking shaft track groove and the locking shaft clearance hole to enter the first bracket locking shaft track groove. The drive shaft passes through the second bracket drive shaft track groove, the drive component drive shaft track groove and the drive shaft clearance hole to enter the first bracket drive shaft track groove. A locking spring 3 is installed between the power shaft and the locking shaft. A main spring 9 is installed between the drive component and the drive shaft.

[0029] Specifically, the schematic diagram of the first support structure is as follows: Figure 3 As shown, the structural diagram of the output component is as follows: Figure 4 , Figure 5 As shown in the diagram, the second support structure is as follows: Figure 6 As shown in the diagram, the driving component structure is as follows: Figure 7 As shown.

[0030] In a dual-power conversion mechanism, when in the dual-split state, the driving component, output component, locking spring, and main spring are in a vertical position. The locking shaft, under the tension of the locking spring, is located in the groove between the locking shaft track grooves of the first and second supports, thus locking the mechanism. A schematic diagram of the dual-split state is shown below. Figure 8 As shown.

[0031] When a dual-splitter to main power conversion is required, the drive shaft rotates counterclockwise, driving the drive component to rotate. Because the locking shaft is confined within the intermediate groove of the first and second bracket locking shaft track grooves, the output component cannot rotate, thus restricting the drive shaft's movement and causing the main spring to stretch and store energy. When the drive component rotates to the desired angle, the unlocking lever on the drive component pushes the locking shaft upwards, causing it to move upwards along the intermediate groove of the first and second bracket locking shaft track grooves and the locking shaft clearance hole of the output component. Simultaneously, the locking spring is stretched. After the locking shaft is pushed out of the intermediate groove of the first and second bracket locking shaft track grooves, as the drive shaft continues to drive the drive component to rotate counterclockwise, the drive shaft moves within the corresponding track groove under the influence of the main spring's tension, causing the output component to begin rotating. Simultaneously, the locking shaft also moves within the first and second bracket locking shaft track grooves until it reaches the end groove of the first and second bracket locking shaft track grooves. At this point, the output component has rotated to its final position, completing the dual-splitter to main power conversion process. Specifically, as follows... Figure 9 , Figure 10 As shown.

[0032] When the main power needs to be switched to dual-distribution mode, the drive shaft rotates clockwise, driving the drive component to rotate. Because the locking shaft is confined within the end grooves of the first and second bracket locking shaft track grooves, the output component cannot rotate, and the drive shaft is also restricted from movement, thus stretching the main spring to store energy. When the drive component rotates to the desired angle, the unlocking lever pushes the locking shaft upwards, causing it to move upwards along the end grooves of the first and second bracket locking shaft track grooves and the locking shaft clearance hole of the output component, while the locking spring is stretched. When the locking shaft is pushed out of the end grooves of the first and second bracket locking shaft track grooves, under the influence of the main spring's tension, the drive shaft moves within the corresponding track groove, causing the output component to begin rotating. Simultaneously, the locking shaft also moves within the corresponding track groove until it reaches the middle of the corresponding track groove. At this point, the output component rotates to its position, and the locking shaft, under the tension of the locking spring, moves into the middle groove of the corresponding locking shaft track groove, thus completing the main power switching to dual-distribution mode. A schematic diagram of the state before unlocking during the main power switching to dual-distribution mode is shown below. Figure 11 As shown in the diagram, the conversion completion status is the same as... Figure 8 As shown.

[0033] The process of switching from dual-split power to backup power and vice versa is similar to the process of switching from dual-split power to main power and vice versa; the power shaft simply rotates in the opposite direction.

[0034] The present invention provides a dual power supply conversion mechanism. By setting a main spring and a locking spring, and through the cooperation of the locking shaft with the corresponding bracket locking shaft track groove and the drive shaft with the drive shaft track groove, the mutual conversion between the main power supply, the backup power supply and the dual power supply can be realized. The mechanism requires fewer parts, has a simple structure and assembly operation, and occupies less space.

[0035] Furthermore, since both the first and second bracket locking shaft track grooves are arc-shaped structures, and the first and second bracket locking shaft track grooves are respectively provided with a middle groove and an end groove, the dual power supply conversion mechanism achieves main and backup interlocking. Only one state can be achieved at a time when switching to the main power supply or the backup power supply, which prevents the short circuit risk of the main and backup power supplies closing at the same time, and the reliability is relatively high.

[0036] The optimized design features arc-shaped tracks for the first support drive shaft, the second support drive shaft, and the drive component drive shaft, which can mate with the first support lock shaft track and the second support lock shaft track, respectively located above and below the power shaft.

[0037] In the optimized design, both the first bracket lock shaft track groove and the first bracket drive shaft track groove are blind grooves, which can achieve vertical positioning of one end of the lock shaft. The vertical positioning of the other end of the lock shaft can be achieved by the outer shell of the entire mechanism, which is not shown in this invention.

[0038] The optimized locking shaft clearance hole is an elongated hole, while the drive shaft clearance hole is a round hole, allowing the locking shaft to move up and down only along the elongated hole to achieve unlocking or locking. When the locking shaft moves along the locking shaft track groove of the first bracket and the drive shaft track groove of the first bracket, the drive shaft moves within the corresponding track groove, and the output component rotates.

[0039] Furthermore, the power shaft can be driven to rotate manually or by motor 1, and the dual power conversion mechanism can realize both manual and automatic driving modes.

[0040] Furthermore, the first bracket is provided with a first bracket center hole 201, the second bracket is provided with a second bracket center hole 602, the output component is provided with an output component center hole 503, and the drive component is provided with a drive component center hole 802. The power shaft passes through the corresponding center hole, and the power shaft is rotatably connected to the first bracket, the second bracket, and the output component. The power shaft and the drive component can be fixedly connected by a key connection or other means, so that the drive component rotates together with the power shaft.

[0041] The optimized design allows for easy assembly and disassembly of the second bracket, which is fixed to the first bracket via a 204 hook or bolts.

[0042] Furthermore, the output unit is equipped with a switch opening / closing position indicator 501, which makes it convenient for operators to check whether the switching is correct.

[0043] Furthermore, the driving component consists of two driving plates, which are fixedly connected by a main spring mounting beam 804. One end of the main spring is mounted on the main spring mounting beam, which facilitates the assembly and disassembly of the main spring.

[0044] In summary, the dual power conversion mechanism provided by this invention can realize dual power conversion operation, requires fewer parts, has high reliability, has a relatively simple structure and assembly operation, and occupies less space.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
