Description

Technical Field

[0001] This utility model relates to the field of power-off switch technology, specifically a power-off switch. Background Technology

[0002] In electrical systems of vehicles, ships, and other vehicles that require high current power, emergency power-off switches are often required. Taking motor vehicles as an example, when a vehicle encounters a major emergency, it is necessary to immediately cut off the power, stop the engine, and stop the vehicle. This means quickly disconnecting the main power supply to the entire vehicle, shutting off the engine, stopping the vehicle immediately, turning on the backup emergency lights, and evacuating the passengers.

[0003] Existing rotating devices typically employ an integrated design of the rotating rod and handle. While this structure, achieved through injection molding, forging, or machining, ensures structural strength, it suffers from several significant drawbacks: The need for complex molds or high-precision machining significantly increases mold development and processing costs. Furthermore, if either the handle or the rod experiences wear or breakage, the entire assembly must be replaced. Actual testing shows that this type of maintenance takes an average of 2.5 times longer than a separate design, incurring additional costs for replacing the entire assembly, resulting in resource waste. Additionally, the integrated structure struggles to adapt to different operating conditions; adjusting the handle shape or rod length necessitates re-molding, extending product iteration cycles by approximately 40% and failing to meet the demands of rapid market response.

[0032] like Figure 1-7 This is a schematic diagram of a preferred embodiment of the present invention for a power-off switch. In this embodiment, the power-off switch includes a base plate 2 and a protective shell 1. The base plate 2 is fixedly connected to the bottom of the protective shell 1. Mounting positions 21 are provided at both ends on the surface of the base plate 2. Connecting copper busbars 7 are installed in the mounting positions 21. A connecting cavity 11 is provided inside the protective shell 1. A connecting post 4 is fixedly connected to the top of the surface of the protective shell 1. A rotating cavity 41 is provided inside the connecting post 4 and communicates with the connecting cavity 11. A rotating assembly 5 is rotatably connected inside the rotating cavity 41. A conductive sheet 6 is connected to the bottom of the rotating assembly 5. The rotating assembly 5 drives the conductive sheet 6 to achieve contact between the surface of the conductive sheet 6 and the ground surface of the conductive sheet 6. The connecting copper busbar 7 is movably connected to the surface. A rotating handle 3 is rotatably connected to the top of the connecting column 4, and the bottom of the rotating handle 3 is connected to the rotating component 5. The operator operates the rotating handle 3 to drive the rotating component 5, causing the conductive sheet 6 to rotate with the rotating component 5 and movably connect with the connecting copper busbar 7. Combined with the structural design of this utility model, complex molds and high-precision integrated processes are avoided, significantly reducing mold development costs and processing costs. When a local component is damaged, only the corresponding split component needs to be replaced, without replacing the whole, thus saving component replacement costs, reducing resource waste, and the split structure facilitates the integration of different functional modules, is compatible with various workpieces or usage environments, and improves the versatility and expandability of the device.

[0033] In this embodiment, the rotating assembly 5 includes a rotating rod 51 and a spring 52. The rotating rod 51 is rotatably connected to the rotating cavity 41, and the spring 52 is sleeved on the lower surface of the rotating rod 51. The rotating rod 51 also includes a rotating block 511 and a driving rod 512. The driving rod 512 is fixedly connected to the bottom of the rotating block 511, and the top surface of the rotating block 511 is rotatably connected to the inner wall of the rotating cavity 41. The spring 52 is sleeved on the surface of the driving rod 512, with one end of the spring 52 abutting against the rotating block 511 and the other end abutting against the conductive sheet 6. The bottom of the driving rod 512 is inserted into the conductive sheet 6. Specifically, the operator operates the rotating handle 3 to drive the rotating block 511 to rotate, and through the rotating block 511… The top surface is evenly distributed with protrusions 5112. With the cooperation of grooves 42 on the inner wall of the rotating cavity 41 at the position opposite to the protrusions 5112, the protrusions 5112 on the surface of the rotating block 511 disengage from the grooves 42, so that the protrusions 5112 abut against the inner wall of the rotating cavity 41, causing the rotating rod 51 to move downward. Driven by the rotating rod 51, the conductive sheet 6 rotates and moves downward, so that the conductive sheet 6 contacts the connecting copper busbar 7. At the same time, the spring 52 is in a contracted state when it is pressed down by the rotating block 511. When the protrusions 5112 on the surface of the rotating block 511 rotate back to the grooves 42, it can be quickly released, thereby achieving the effect of rapid separation of the conductive sheet 6 and the connecting copper busbar 7.

[0034] In this embodiment, the top surface of the rotating block 511 is evenly connected with protrusions 5112, and the surface of the rotating block 511 is provided with connecting grooves 5113 between the protrusions 5112. A connecting rod 31 is fixedly connected to the bottom of the rotating handle 3, and the connecting rod 31 passes through the rotating cavity 41 and connects with the connecting groove 5113. Under the action of the operator, the rotating handle 3 is operated to drive the rotating rod 51 to rotate. The surface of the rotating block 511 is provided with a sealing groove 5111, and a sealing ring 513 is sleeved in the sealing groove 5111. The outer wall of the sealing ring 513 contacts the inner wall of the rotating cavity 41. This structural design increases the sealing performance between them.

[0035] In this embodiment, a connector 61 is provided in the middle of the surface of the conductive sheet 6, and a drive rod 512 is connected to the connector 61. Through the connection between the connector 61 and the drive rod 512, the rotating rod 51 rotates, causing the conductive sheet 6 to rotate. Contact points 62 are fixedly connected on both sides of the connector 61 on the surface of the conductive sheet 6. The contact points 62 are movably connected to the connecting copper busbar 7. The contact points 62 are in contact with the connecting copper busbar 7 to realize the current conduction function.

[0036] In this embodiment, the inner wall of the rotating cavity 41 is provided with a groove 42 at the position opposite to the convex 5112, and the groove 42 is movably connected to the convex 5112. Through the cooperation between the convex 5112 and the groove 42, the downward displacement function of the rotating rod 51 is realized.

[0037] In this embodiment, a connecting rod 31 is fixedly connected to the bottom of the rotating handle 3, and the connecting rod 31 passes through the rotating cavity 41 and is connected to the connecting groove 5113.

[0038] In this embodiment, a guide post 22 is fixedly connected to the surface of the mounting position 21, and a guide hole 71 is opened on the surface of the conductive sheet 6 at a position opposite to the guide post 22, and the guide post 22 is connected inside the guide hole 71. This structural design facilitates the rapid installation of the copper busbar 7.

[0039] In this embodiment, a threaded hole 12 is provided on the inner wall surface of the connecting cavity 11, and a connecting hole 23 is provided on the surface of the base plate 2 at the position opposite to the threaded hole 12. The connecting hole 23 and the threaded hole 12 are connected by fasteners. This structural design allows the base plate 2 and the protective shell 1 to be fixedly connected by fasteners.

It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
