[0039] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0040] like Figure 1-4 As shown, an electric switching switch comprises:

[0041] Rack 100;

[0042] An input-end conductive block 200 , which is fixedly mounted in the frame 100 ;

[0043] A first output-end conductive block 310 and a second output-end conductive block 320, wherein the first output-end conductive block 310 and the second output-end conductive block 320 are arranged in the frame 100 at intervals;

[0044] A driving device 400, the driving device 400 is installed on the frame 100;

[0045] A driving transmission assembly, which is connected to the driving device 400 and is adapted to be driven to rotate by the driving device 400;

[0046] A vertical transmission mechanism, the vertical transmission mechanism is connected to the drive transmission assembly;

[0047] A first connecting conductive block 510 and a second connecting conductive block 520, wherein the first connecting conductive block 510 and the second connecting conductive block 520 are mounted on corresponding vertical transmission mechanisms;

[0048] The vertical transmission mechanism is suitable for driving the first connecting conductive block 510 and the second connecting conductive block 520 to move vertically in opposite directions, so that the first connecting conductive block 510 connects the input end conductive block 200 and the first output end conductive block 310 or the second connecting conductive block 520 connects the input end conductive block 200 and the second output end conductive block 320.

[0049] In this embodiment, if Figure 1 and Figure 3-4As shown, the driving device 400 drives the driving transmission components on both sides to rotate, and realizes the vertical movement of the first connection conductive block 510 and the second connection conductive block 520 in independent and opposite directions through the vertical transmission mechanism connected to the driving transmission components. In this way, when it is necessary to switch from the input end conductive block 200 being connected to the first output end conductive block 310 through the first connection conductive block 510 to the input end conductive block 200 being connected to the second output end conductive block 320 through the second connection conductive block 520, only the driving device 400 needs to drive, so that the first connection conductive block 510 can be raised and disconnected from the input end conductive block 200 and the first output end conductive block 310, and at the same time, the second connection conductive block 520 descends and contacts and connects the input end conductive block 200 and the second output end conductive block 320, thereby realizing the switching of power supply, and ensuring fast switching speed, high operation accuracy and good stability.

[0050] Specifically, Figure 1 As shown, the driving device 400 is a motor.

[0051] Specifically, Figure 1 and Figure 3 As shown, the drive transmission assembly includes a pair of transmission gears 600;

[0052] A pair of transmission gears 600 are arranged on both sides of the driving device 400;

[0053] The driving device 400 is adapted to mesh with a pair of transmission gears 600 to drive the transmission gears 600 on both sides to rotate.

[0054] In this embodiment, if Figure 3 As shown, the motor is provided with a driving gear, and the transmission gear 600 is arranged on both sides of the driving device 400, i.e., the motor, and meshes with the driving gear of the output shaft of the motor. When the motor is working and rotating the output shaft, the transmission gears 600 on both sides are driven to rotate together through meshing. This gear transmission method can ensure that the force on both sides is uniform and the operation is smooth. The rotation speed and direction of the transmission gears 600 on both sides are consistent, and the subsequent vertical transmission mechanism can be driven in sequence to make the speed of the vertical transmission mechanism consistent, thereby avoiding faults caused by differential speed.

[0055] Specifically, Figure 1-4 As shown, the vertical transmission mechanism can be structured as follows:

[0056] A pair of lead screws, the pair of lead screws are rotatably mounted on the frame 100, one end of the lead screw is connected to the driving transmission assembly;

[0057] A pair of nuts, a pair of nuts are sleeved on the corresponding screw;

[0058] The driving transmission assembly is suitable for driving the nut to move along the axial direction of the lead screw through the lead screw.

[0059] In this embodiment, if Figure 1 and Figure 3-4 As shown, when the lead screw rotates, the nut will move along the axial direction of the lead screw. At this time, the first connection conductive block 510 and the second connection conductive block 520 connected to the nut are driven by the nut to move vertically to actually switch the circuit connection state. This lead screw and nut transmission method can accurately convert rotational motion into linear motion, so that the trajectory of the first connection conductive block 510 and the second connection conductive block 520 is accurate and the positioning is reliable, thereby ensuring good contact between the input end conductive block 200 and the first output end conductive block 310 and the second output end conductive block 320, and realizing precise and controllable circuit switching. The lead screw and nut transmission adopts a symmetrical double lead screw design to ensure that the two-way switching action is synchronized and avoid faults caused by improper contact. At the same time, the lead screw transmission has a self-locking function, which can keep the state unchanged and improve system reliability.

[0060] Specifically, Figure 1-4 As shown, the rack 100 is a double-layer structure, which includes an upper layer and a lower layer;

[0061] The upper part and the lower part are each provided with an independent input end conductive block 200, a first output end conductive block 310 and a second output end conductive block 320;

[0062] The vertical transmission mechanism passes through the upper layer part and the lower layer part and is connected with the driving transmission assembly.

[0063] In this embodiment, if Figure 1 As shown, when the driving device 400 is working, it can simultaneously drive the upper and lower layers of the screw nuts to move and control the synchronous switching of the two circuits. This design method has a compact mechanical structure and high space utilization.

[0064] Specifically, Figure 1-4 As shown, the contact surface of the first connection conductive block 510 with the input end conductive block 200 and the first output end conductive block 310, and the opposite surface of the contact surface of the second connection conductive block 520 with the input end conductive block 200 and the second connection conductive block 520 are non-contact surfaces;

[0065] An insulating epoxy pressing block 700 is mounted on the non-contact surface of the first connecting conductive block 510 and the second connecting conductive block 520 .

[0066] In this embodiment, if Figure 1-4As shown, the insulating epoxy pressing block 700 is provided to isolate the non-contact surface of the first connecting conductive block 510 and the second connecting conductive block 520, and prevent the first connecting conductive block 510 and the second connecting conductive block 520 from contacting with other components such as the frame 100 to generate arc or short circuit when the first connecting conductive block 510 and the second connecting conductive block 520 move up and down, and the insulating epoxy pressing block 700 is made of epoxy resin material with good insulation performance, and is bonded to the non-contact surface of the first connecting conductive block 510 and the second connecting conductive block 520. When the first connecting conductive block 510 and the second connecting conductive block 520 move up and down with the nut driven by the lead screw, the insulating epoxy pressing block 700 can effectively block the contact between its non-contact surface and external components, and prevent the generation of arc or short circuit, thereby ensuring the safe and reliable operation of the switch.

[0067] Specifically, Figure 3 As shown, the input-end conductive block 200 , the first output-end conductive block 310 , and the second output-end conductive block 320 are all provided with connection holes suitable for connection.

[0068] In this embodiment, the connection hole can be used to achieve a detachable connection with a wire or cable of an external circuit. The number, specification, arrangement and other parameters of the connection holes can be set according to actual use needs. For example, multiple connection holes can be set to meet the connection requirements of multiple cables. The internal structure of the connection hole can adopt a standard structure such as a threaded hole or a hexagonal hole.

[0069] Specifically, Figure 2-3 As shown, water cooling pipelines are provided in the input end conductive block 200, the first output end conductive block 310, and the second output end conductive block 320;

[0070] A water cooling interface 800 connected to a water cooling pipeline is provided on the edge surfaces of the input end conductive block 200 , the first output end conductive block 310 , and the second output end conductive block 320 .

[0071] In this embodiment, if Figure 2 As shown, the water cooling pipeline is used to transport coolant and take away the heat generated during operation. The water cooling interface 800 realizes the input and output of coolant. The water cooling design can greatly improve the overcurrent capacity and service life, and is suitable for high-power working conditions.

[0072] Specifically, Figure 1-4 As shown, the rack 100 is provided with equipment mounting holes.

[0073] In this embodiment, the position, quantity and size of the equipment mounting holes can be designed according to actual needs to meet the installation requirements of different external devices. The structure of the equipment mounting holes can adopt standard structures such as threaded holes, long holes, guide holes, etc.
