It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0035] See also Figures 1 to 8 The embodiment of the present invention provides a permanent magnet motor dedicated voltage conversion junction box, which includes a box body 1, a plurality of waterproof connectors 2 on the side of the box body 1, a wiring board 4 installed inside, and further includes:

[0036] There are two sets of connection blocks, namely a plurality of one-row connection blocks 5 and a plurality of two-row connection blocks 6. The two sets of connection blocks are fixed side by side on the terminal block 4.

[0037] The adjustment unit 3 includes a driving part, a transmission frame 37 and a transmission part;

[0038] The driving part is installed on the box body 1, is connected to the transmission frame 37, and drives the transmission frame 37 to move horizontally inside the box body 1;

[0039] The transmission part is fixed to the transmission frame 37 and moves along with the movement of the transmission frame 37;

[0040] The connecting piece 312 has one end rotatably mounted on a row of connecting seats 5 and is also in transmission connection with the transmission part;

[0041] The transmission part drives the connecting piece 312 to rotate horizontally, so that the conductive contact at the other end of the connecting piece 312 switches contact between the first row of connecting sockets 5 and the second row of connecting sockets 6, and the first row of connecting sockets 5 and the second row of connecting sockets 6 both have independent circuit structures.

[0042] It should be noted that: in this device, both rows of connection sockets are conductive elements and have independent circuit structures, and the two independent circuit structures have different voltages. The connection piece 312 has a conductive contact piece. When the connection piece 312 is rotated and adjusted, it contacts the first row of connection sockets 5 or the second row of connection sockets 6, thereby realizing voltage rotation.

[0043] The adjustment unit 3 is the main structure for adjusting the connection state of the connecting piece 312. The setting of the adjustment unit 3 can realize quick adjustment of the circuit without disassembling the box body 1, which has higher practicality.

[0044] In the embodiments of the present invention, please refer to Figure 3The driving part includes a rotating plate 31 that rotates on the outside of the box body 1 through a connecting shaft 35. A screw 33 passes through the rotating plate 31. A handle 32 is fixed to one end of the screw 33, and the screw 33 is driven to rotate by the handle 32 so that the other end of the screw 33 is pressed against the box body 1. A first positioning slide 34 is also provided along the length direction on the rotating plate 31;

[0045] At the same time, a second positioning slide 36 is provided on one side of the box body 1;

[0046] One end of the transmission frame 37 is slidably connected to the inner wall of the box body 1 , and a transmission shaft 38 is vertically fixed to the end. The transmission shaft 38 passes through the second positioning slide 36 and extends to the inside of the first positioning slide 34 .

[0047] It should be noted that: for the adjustment of the drive frame 37 of the driving force, that is, first, the handle 32 is used to drive the rotating plate 31 to rotate, and the transmission shaft 38 on the transmission frame 37 passes through the second positioning slide 36 and enters the first positioning slide 34. Therefore, when the rotating plate 31 rotates, it can generate a force on the transmission shaft 38, and cooperate with the limiting effect of the second positioning slide 36 to achieve horizontal movement of the entire transmission frame 37, that is, to achieve the adjustment of the position of the transmission frame 37;

[0048] The handle 32 is connected to the rotating plate 31 through the screw 33. Therefore, when the handle 32 is rotated, the screw 33 can be fed and moved, so that the other end of the screw 33 can be pressed against the box body 1. In the pressed state, the entire driving part can be locked to ensure the stability of the transmission frame 37.

[0049] In the embodiments of the present invention, please refer to Figure 4 and Figure 5 The transmission part includes a transmission plate 39 fixed on the transmission frame 37, and the upper and lower surfaces of the transmission plate 39 near the other end are rotatably connected to the transmission sub-plate 310, and the transmission pin 311 is vertically fixed at the position near the other end of the transmission sub-plate 310;

[0050] At the same time, one end of the connecting piece 312 is rotatably connected to a row of connecting seats 5 through an axis, and a third positioning slide 313 close to the axis and along the length direction is opened at the edge of the connecting piece 312, and the transmission pin 311 extends into the inside of the third positioning slide 313.

[0051] It should be noted that: with respect to the coordinated transmission between the transmission part and the transmission frame 37, when the transmission frame 37 moves, it can directly drive the transmission plate 39 to move, and the transmission plate 39 is connected to the connecting plate 312 through the transmission sub-plate 310 and the transmission pin 311, that is, when the transmission plate 39 moves, the transmission pin 311 is used to generate a force on the connecting plate 312 to drive the connecting plate 312 to rotate, thereby replacing and adjusting the circuit connected to the connecting plate 312.
