[0029] The present invention will be further described in detail below with reference to the accompanying drawings.

[0030] Please refer to Figure 1 , an electronic mechanical switch according to an exemplary embodiment of the present invention is mainly applied to low-current and low-voltage control circuits in the rail transit industry, ships, and elevator industry, and includes a switch operating member 1, a switch mechanical positioning member 2, a transfer member 3, and an electronic control member 4 connected in sequence from top to bottom. The switch mechanical positioning member 2 is used to orient the switch operating member 1 at a specific angle and position. The transfer member 3 is used to convert the mechanical action acting on the switch operating member 1 into an electrical signal and output it to the electronic control member 4.

[0031] In this embodiment, the switch operating member 1 can be a rotary handle mechanism or a key lock cylinder mechanism. Considering safety and reliability, and to avoid misoperation or for dedicated operation, the switch operating member in this embodiment is preferably a key lock cylinder mechanism. Please refer to Figure 2 , the switch operating member 1 includes: a connecting sleeve 11, which is provided with a decorative ring at the top and an internal thread on the inner side wall; a lock cylinder 12 installed in the connecting sleeve 11 and cooperating with the key 14. A lock sleeve 13 is sleeved on the lock cylinder 12, and an external thread matching the internal thread of the decorative ring is provided on the outer periphery of the upper end of the lock sleeve, so that the lock sleeve can be sleeved in the connecting sleeve 11.

[0032] It should be noted that the key cylinder mechanism in this embodiment is a prior art, such as a pin tumbler lock with multiple groups of pins disclosed in the patent application No. CN201820626146.0. The principle of the conventional key cylinder mechanism to realize the relative rotation of the key and the cylinder with respect to the sleeve is as follows: The key cylinder 12 of the key cylinder mechanism is provided with a key hole for inserting the key 14. The upper pin holes and the lower pin holes are respectively provided on the sleeve 13 and the key cylinder 12 and are communicated with each other. The spring, the upper pin and the lower pin are arranged in sequence along the axial direction of the upper pin hole. The spring is located in the upper pin hole. One end of the upper pin is located in the upper pin hole and abuts against the spring, and the other end extends into the lower pin hole under the action of the spring and abuts against the lower pin. The lower pin can move under the action of the key to push the upper pin to overcome the elastic force of the spring and move to the position tangent to the outer wall of the key cylinder 12. There are multiple pin assemblies, which are divided into two groups, and each group includes at least three pin assemblies. A number of pin assemblies in the same group are arranged at intervals in sequence along the direction in which the key 14 is inserted into the key hole. The part of the key 14 inserted into the key hole is in the shape of a plate strip, which includes upper and lower planes. Concave key patterns are provided on both planes, and the key patterns on each plane correspond to the lower pins in two groups of pin assemblies one by one. When the key is inserted into the key hole in the forward or reverse direction and in place, each lower pin can be elastically inserted into the corresponding key pattern on one plane under the action of the corresponding spring, so that each upper pin is tangent to the key cylinder 12. At this time, the key cylinder 12 can rotate relative to the sleeve 13.

[0033] Please refer to Figure 3 , in this embodiment, the switch mechanical positioning component 2 for realizing the orientation of the specific angle and position of the switch operation component 1 includes a positioning disk 21, a positioning box 22 and a positioning box cover 23 which are clamped in sequence from top to bottom. The inside of the positioning box is a cavity, and a positioning piece assembly 24 sleeved on the key cylinder 12 is arranged in this cavity. The positioning piece assembly 24 is used to position the key cylinder 12 and control the total rotation angle. A positioning structure sleeved on the key cylinder 12 and capable of rotating together with the key cylinder 12 is arranged below the positioning piece assembly 24. The positioning structure includes a positioning cam 25 and multiple groups of slider-spring combination structures 26 arranged at intervals along the circumference of the positioning cam 25.

[0034] Specifically, the slider-spring combination structure 26 includes a spline that rotates synchronously with the key cylinder, several sliders clamped in the spline tooth grooves, and a spring with one end connected to the slider. The other end of the spring is constrained to the side wall of the positioning box 22.

[0035] The principle of the switch mechanical positioning component to achieve the orientation of the switch operating component at a specific angle and position is further described as follows: Since the lock core in the switch operating component 1 is connected to the slider by a spline, when the lock core 12 rotates, it drives the positioning cam 25 to rotate. By rotating the positioning cam 25, the slider is squeezed, so that the slider makes a linear motion of compressing the spring under the constraint of the slots of the positioning box 22 and the positioning box cover 23, thereby achieving the function of rotating to various angles. Among them, the rotation angle stroke of the switch operating component is jointly limited by the positioning piece assembly 24 and the positioning box 22.

[0036] Please refer to Figure 4 , in this embodiment, the electronic control component 4 includes a protection box 41 and a control board 42 located inside the protection box 41. The control board 42 includes a disk-shaped connecting board and an integrated board located below the connecting board. At least one contact 44 is provided on the connecting board, and at least one relay unit 421 is integrated on the integrated board. The contacts 44 and the relay units 421 are arranged in one-to-one correspondence and electrically connected. The transfer component 3 is arranged above the control board 42 inside the protection box 41.

[0037] Please continue to refer to Figure 4 , the transfer component 3 includes a transfer box 31 and 332. Among them, the upper and lower inner side walls of the transfer box 31 are respectively provided with threads for cooperating with the positioning box 22 and the protection box 41, so that the switch operating component 1, the switch mechanical positioning component 2, the transfer component 3 and the electronic control component 4 are connected into a whole from top to bottom. The top end of the transfer cam 32 is fixedly connected to the switch mechanical positioning component 1. Specifically, the top end of the transfer cam 32 is fixedly connected to the bottom end of the spline, so that the transfer cam 32 can rotate synchronously with the rotation of the switch operating component 1. The bottom end of the transfer cam 32 is relatively fixed to the center of the connecting board. A spring ejector pin 33 is fixedly connected to one side of the transfer cam 32. The end of the spring ejector pin 33 can contact the contact 44 on the connecting board to trigger the corresponding relay unit 421, thereby converting the mechanical action of the switch operating component 1 into an electrical signal and outputting it to the electronic control component.

[0038] The above-mentioned adapter component is connected point-to-point by a conversion cam 32, a connecting plate and a spring ejector pin 33, and the above-mentioned mechanical action is converted into a signal command and output to the electronic control component below. The adapter component 3 plays a connecting role here. When in use, when the switch operating component 1 completes a certain angle of rotation under the control of the switch mechanical positioning component 2, the relay unit 421 of the corresponding gear will be triggered, thereby achieving the output of the mechanical action converted into an electrical signal. The relay unit 421 is used because the relay unit has good sealing and stability; thereby ensuring normal operation in a low-current and low-voltage circuit. This multi-gear mechanical control relay sends a signal to control the circuit, which can replace the original exposed contact module to control the on-off. The rotary mechanical structure used to achieve the required gear can also be more accurate and reliable.

[0039] In some preferred embodiments, two locking pillars 43 are extended from the bottom of the protection box 41 to facilitate installation of the electronic mechanical switch in a low-current and low-voltage control loop.
