DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] It should be understood that the terms "include / comprise", "consist of..." or any other variations are intended to cover non-exclusive inclusion, so that a product, device, process or method that includes a series of elements includes not only those elements, but also may include other elements not explicitly listed when necessary, or also includes elements inherent to such product, device, process or method. In the absence of more restrictions, the elements defined by the sentence "include / comprise...", "consist of..." do not exclude the presence of other identical elements in the product, device, process or method that includes the elements.

[0029] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] See also Figure 1-Figure 10 An embodiment of the present invention provides: a device for detecting the service life of an induction switch, comprising a base plate 100, an operating table 101 being provided on the base plate 100, a DC reduction motor 200 being installed on the base plate 100, a first frame 300 and a second frame 301 being installed on the base plate 100, a gap being provided between the first frame 300 and the second frame 301, symmetrical induction windows 304 being provided on the first frame 300 and the second frame 301, a rocker arm assembly being connected to the first frame 300, the rocker arm assembly being used to block the induction window 304 so that it is induction-induced, a slideway 305 being connected to the first frame 300 and the second frame 301, a slide seat 309 being slidably provided on the slideway 305, a driving component for driving the slide seat 309 to slide being provided on the first frame 300 and the second frame 301, an inductor fixing portion being installed on the slide seat 309, and a DuPont terminal 312 being provided on the inductor fixing portion.

[0031] According to the scheme of the present invention, the swing arm assembly can be periodically swung. The swing arm assembly periodically blocks the sensing window 304 during the swinging process, so that the sensing switch is sensed. After the sensing switch is sensed, the signal is transmitted to the operating table 101, so that the control component of the operating table 101 controls the DC reduction motor 200 to perform an execution operation. For example, the speed and number of turns of the DC reduction motor 200 can be set to fit the actual motor motion formation, and the corresponding load can be added to the output end of the DC reduction motor 200 to keep the same as the actual scene. When the sensing window 304 is in a non-sensing state, the DC reduction motor 200 performs a reset execution action. Specifically, the time interval of the non-sensing state can be set through the operating table 101, such as simulating the elevator door closing cycle, the escalator deceleration time, etc. By setting the motion cycle of the swing arm assembly, the number of inductions of the sensing window 304 in a unit time is obtained, and then the detection of the sensing switch is completed. The operating table 101 is provided with a data processing and analysis module for processing and recording the data. Since the storage and recording are relatively mature designs in existing detection equipment and electronic equipment, they are not described in detail here.

[0032] In order to test the test performance of the sensing switch at different positions, a slide 305 is installed on the sensing window 304 of the present invention, so that the position between the sensing switch and the sensing window 304 can be adjusted. The rocker arm assembly of the present invention performs periodic swings to simulate the periodic triggering in the actual use scenario, and can quickly and efficiently detect the service life of the sensing switch.

[0033] In one embodiment, the rocker arm assembly includes a driving assembly 302 installed on a first frame 300, and a rotating shaft 303 is rotatably connected between the first frame 300 and the second frame 301, and the rotating shaft 303 is connected to the output end of the driving assembly 302. At least one rocker arm body 3031 is installed on the rotating shaft 303, and a slot 3032 is provided at the end of each rocker arm body 3031. A locking piece 3033 is detachably connected to the slot 3032, and the slot 3032 is used to place different obstacles and is fixed by the locking piece 3033.

[0034] According to the solution of the present invention, when the device is started, the driving component 302 starts working on the first frame 300. The driving component 302 can be a reduction motor or other power device, which can provide stable rotational power according to actual needs. The output end of the driving component 302 is connected to the rotating shaft 303. When the driving component 302 is started, it will drive the rotating shaft 303 to rotate between the first frame 300 and the second frame 301. At least one rocker body 3031 is installed on the rotating shaft 303. As the rotating shaft 303 rotates, the rocker body 3031 will swing periodically. According to the detection needs, different obstacles, such as metal sheets, plastic sheets, etc., can be placed in the card slot 3032 and fixed by the locking member 3033 to ensure that the obstacles will not fall off during the swinging process. When the rocker body 3031 swings to the position of the sensing window 304, the obstacles on it will cover the sensing window 304, so that the sensor generates a sensing signal. The sensing signal is transmitted to the operating console 101 for subsequent data processing and control operations. Under the action of the driving component 302, the rocker arm assembly continues to swing periodically, thereby periodically blocking and sensing the sensing window 304, simulating the periodic triggering in the actual use scenario, and realizing the detection of the service life of the sensing switch.

[0035] In one embodiment, the driving component wraps the third screw 400 installed on the first frame 300 and the second frame 301, and a fourth support plate 402 is installed at the end of the slide 305. The third screw 400 is rotatably connected to the fourth support plate 402. A support plate 403 is connected to the bottom of the slide seat 309. The support plate 403 is provided with a threaded sleeve that is threadedly connected to the third screw 400, and a rocker 401 is connected to the end of the third screw 400.

[0036] According to the solution of the present invention, the driving component is mainly composed of a third screw 400, a fourth support plate 402, a support plate 403 and a threaded sleeve. The third screw 400 passes through the end of the slideway 305 and is rotatably connected to the fourth support plate 402. When the slide 309 needs to be driven to slide on the slideway 305, the third screw 400 is rotated by rotating the rocker 401. Since the threaded sleeve on the support plate 403 is threadedly connected to the third screw 400, the threaded sleeve will move along the axial direction of the third screw 400, thereby driving the slide 309 to slide on the slideway 305, and adjusting the position of the slide 309 and the sensor fixing part. Thereby changing the distance between the sensing window 304 and the sensor to adapt to the sensing switch testing requirements at different positions and angles; while the rocker arm assembly is performing periodic swinging, the user can adjust the position of the sensor through the driving component to simulate the periodic triggering of the sensing switch at different positions and angles in actual usage scenarios, thereby achieving more comprehensive and accurate life detection of the sensing switch; by combining the periodic swinging of the rocker arm assembly and the position adjustment function of the driving component, the device can more comprehensively simulate the triggering of the sensing switch in actual usage scenarios, thereby making the detection result closer to actual usage.

[0037] In one embodiment, a scale 308 is installed on the first frame 300 and the second frame 301 , and a pointer is installed on the slide 309 , and the pointer is located above the scale 308 .

[0038] By adopting the solution of the present invention, the design of the scale 308 and the pointer enables the user to accurately understand the position of the slide 309 on the slide 305, thereby accurately controlling the position of the sensor. By accurately controlling the position of the sensor, the triggering situation of the induction switch in the actual use scenario can be more accurately simulated, thereby improving the accuracy of the test.

[0039] In one embodiment, the sensor fixing portion includes a mounting platform 310 installed above the slide 309, and a positioning plate 311 and a third support plate 313 are connected to the mounting platform 310. The third support plate 313 is threaded with a second screw 317, one end of the second screw 317 is connected to a knob, and the other end is rotatably connected to a first push plate 314, the first push plate 314 is located between the positioning plate 311 and the third support plate 313, a slide plate 315 is provided on the first push plate 314, the slide plate 315 is slidably connected to the third support plate 313, a buffer component is provided on the first push plate 314, and a DuPont terminal 312 is set on the mounting platform 310 and is located between the positioning plate 311 and the first push plate 314.

[0040] By adopting the solution of the present invention, the mounting platform 310 is installed above the slide 309, and the induction switch can be fixed on the slide 309 through the mounting platform 310. The second screw 317 is screwed on the third support plate 313 through a thread, and a knob is connected to one end of the second screw 317. By rotating the knob, the second screw 317 is rotated on the third support plate 313 and moves forward or backward, thereby pushing or pulling the first push plate 314 to move between the positioning plate 311 and the third support plate 313. The slide plate 315 on the first push plate 314 can make the first push plate 314 move smoothly. The buffer component provides buffering when the sensor is impacted by external force to protect the sensor from damage. The DuPont terminal 312 is arranged on the mounting platform 310 and is located between the positioning plate 311 and the first push plate 314, so as to conveniently connect the sensor to the external circuit.

[0041] Optionally, the buffer component includes a second push plate 316 arranged between the positioning plate 311 and the first push plate 314, the second push plate 316 is symmetrically connected with a second slide rod 320 near four edge positions, the second slide rod 320 is slidably connected to the first push plate 314, and each end of the second slide rod 320 is connected to a baffle 318, the baffle 318 is located between the first push plate 314 and the third support plate 313, and each second slide rod 320 is sleeved with a spring 319, and the two ends of the spring 319 are respectively against the first push plate 314 and the second push plate 316.

[0042] By adopting the solution of the present invention, through the elastic restoring force of the spring 319, the buffer component can provide effective buffering when the sensor is impacted by external force, reduce the vibration and displacement of the sensor, and thus protect the sensor from damage.

[0043] In one embodiment, a frame base 307 is connected to the bottom of the first frame 300 and the second frame 301 , and a rib plate 306 is connected between the frame base 307 and the slideway 305 .

[0044] With the solution of the present invention, the main function of the frame base 307 is to provide stable support for the frame, ensuring that the test equipment can remain stable during operation, and the connection strength between the frame base 307 and the slide 305 is enhanced by the ribs 306.

[0045] In one embodiment, a speed regulator 102, a control panel 104 and a display component 105 are provided on the operating table 101. The control panel 104 is used to control the operation and stop of the detection device. The speed regulator 102 is used to adjust the speed of the DC reduction motor 200. The display component 105 is used to display the detection result. A first support plate 106 is installed on the base plate 100. A second support plate 203 is installed on the first support plate 106. There are two second support plates 203. A first slide bar 204 is provided between the two second support plates 203. The output end of the DC reduction motor 200 is connected to a first screw 201. A moving block 202 is threadedly connected to the first screw 201. A detection point 205 matching the moving block 202 is provided on the first support plate 106. The moving block 202 is slidably connected to the first slide bar 204.

[0046] According to the solution of the present invention, the speed regulator 102 on the operating table 101 is used to adjust the rotation speed of the DC reduction motor 200, so as to control the mechanical movement speed during the test. The control panel 104 is responsible for controlling the start and stop of the DC reduction motor 200, as well as the operation and stop of the entire detection device. When the DC reduction motor 200 is running, the first screw 201 connected to its output end will rotate, and the moving block 202 will move along the axial direction of the first screw 201. Since the moving block 202 is slidably connected to the first slide bar 204, it can have a certain stability. When the moving block 202 moves to the detection point 205, the recording is completed once, and the detection result will be displayed through the display component 105 for the operator to read.

[0047] In one embodiment, a coolant tank 500 is installed on the base plate 100, a refrigerator 501 is provided on the coolant tank 500, a pump body 502 is installed on the first support plate 106, and one end of the first screw 201 away from the DC reduction motor 200 is connected to the power input end of the pump body 502. It should be noted that a one-way coupling is provided between the DC reduction motor 200 and the power input end of the pump body 502, that is, when the DC reduction motor 200 rotates in the reverse direction, the pump body 502 does not operate, and the liquid input end of the pump body 502 is connected to the coolant tank 500. A duct portion 503 is installed on the first support plate 106, and a heat exchange box 504 is installed on the base plate 100. The liquid input end of the heat exchange box 504 is connected to the liquid output end of the pump body 502 through the duct portion 503, and the liquid output end of the heat exchange box 504 is connected to the coolant tank 500. A first fan 511 and a second fan 512 are connected to the side wall of the operating table 101. The first fan 511 is used to transport the cold air in the heat exchange box 504 to the operating table 101, and the second fan 512 is used to discharge the heat inside the operating table 101 to the outside.

[0048] According to the solution of the present invention, the coolant tank 500 installed on the base plate 100 is used to store the coolant, the pump body 502 is installed on the first support plate 106, and is connected to the output end of the DC reduction motor 200 through a one-way coupling. The pump body 502 is equivalent to the load in the actual scene. The one-way coupling can be used to select separation or one-way drive connection. When the DC reduction motor 200 rotates forward, the pump body 502 is driven to operate through the one-way coupling. The liquid input end of the pump body 502 is connected to the coolant tank 500 to extract the refrigerated coolant in the coolant tank 500. After the pump body 502 pressurizes the coolant, it is transported to the heat exchange box 504 through the conduit portion 503. The liquid input end of the heat exchange box 504 receives the coolant from the pump body 502. The coolant is cooled in the heat exchange box 504. Heat exchange absorbs heat to cool down the heat exchange box 504. The coolant that has undergone heat exchange flows back to the coolant tank 500 through the liquid output end of the heat exchange box 504. The first fan 511 transports the cold air in the heat exchange box 504 to the operating table 101 to provide cooling effect for the electronic equipment or test equipment inside the operating table 101. The second fan 512 discharges the heat inside the operating table 101 to the external environment to ensure that the temperature inside the operating table 101 is appropriate. Through the coordinated work of the refrigerator 501 and the pump body 502, the circulation speed of the coolant can be controlled. The entire cooling system has a compact structure and occupies a small area. It increases the load of the actual scene for the DC reduction motor 200, and can recover this part of the kinetic energy to cool down the operating table 101 and other components that need to be cooled.

[0049] In one embodiment, a plurality of guide plates 506 are staggeredly arranged in the heat exchange box 504, an infusion channel 505 is provided on the heat exchange box 504, the infusion channel 505 is connected to the catheter portion 503, the output end of the infusion channel 505 is located at the top of the heat exchange box 504, a return hole 510 is provided at the bottom of the heat exchange box 504, the return hole 510 is connected to the coolant tank 500 through a return duct 513, a first ventilation hole 508 is provided on one side of the heat exchange box 504, a filter screen 507 is provided on the first ventilation hole 508, a second ventilation hole 509 is provided on the other side of the heat exchange box 504, and a first fan 511 is located at the position of the second ventilation hole 509.

[0050] By adopting the scheme of the present invention, the coolant is transported to the heat exchange box 504 through the conduit portion 503 under the action of the pump body 502. The DC reduction motor 200 drives the pump body 502 through the one-way coupling, which can ensure that the coolant can flow continuously and stably. The coolant enters the heat exchange box 504 from the top through the infusion channel 505, and after heat exchange with the object to be cooled, it flows out through the return hole 510 at the bottom. Inside the heat exchange box 504, a plurality of staggered guide plates 506 can make the gas fully contact with the coolant for sufficient heat exchange. The return hole 510 is connected to the coolant tank 500 through the return conduit 513. The coolant finally returns to the coolant tank 500 to prepare for the next round of circulation. The first fan 511 is located at the second vent 509 of the heat exchange box 504. The cooled gas enters the inside of the operating table 101 through the first fan 511 to cool the components inside the operating table 101, thereby ensuring the stability of the operating table 101 after long-term operation.

[0051] The present invention can automatically adjust the swing cycle of the rocker assembly, the position of the driving component, the speed of the DC reduction motor 200 and other parameters according to the preset detection program, so as to realize the automatic detection of the induction switch.
