Description

Technical Field

[0001] This invention belongs to the field of elevator technology, specifically a safety monitoring and alarm device. Background Technology

[0002] Escalators are a type of elevator, typically with an inclined structure and circulating steps, used to transport passengers between different floors of a building. They are widely used in places with high pedestrian traffic, such as stations, docks, shopping malls, and airports, providing great convenience for people's travel. However, they also pose certain safety risks. In recent years, elevator safety accidents have been frequent, and the safety performance of elevators needs to be improved.

[0003] Regarding existing related technologies, the inventors believe that the following defects often exist: At the exit of escalators, there is usually a height difference between the steps and the treads, and the treads are higher than the steps. Therefore, when passengers on the escalator reach the exit, if they are not paying attention and forget to lift their feet (such as chatting, playing with their mobile phones, etc.), they are likely to trip on the treads and fall forward. The passengers behind them are continuously transported forward by the escalator, which can easily cause stampede accidents.

[0004] Therefore, the present invention provides a security monitoring and alarm device. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: A safety monitoring and alarm device of this invention includes an escalator; a set of steps is provided on the surface of the escalator; a tread is fixedly connected to the bottom of the escalator, and the tread is located on the upper side of the steps; an alarm is fixedly connected to the surface of the escalator; a groove is formed on the side of the tread near the escalator; a monitoring board is provided inside the groove; a set of springs are evenly distributed between the monitoring board and the tread; a set of guide holes are evenly formed on the side of the tread near the monitoring board; a guide rod is slidably connected inside the guide hole, and one end of the guide rod extending outside the guide hole is fixedly connected to the monitoring board; a contact point one is fixedly connected to the end of one of the guide holes, and a contact point two is fixedly connected to the end of the guide rod corresponding to contact point one; contact point one and contact point two are connected to the alarm via a processor. Connection; At the exit of an escalator, there is usually a height difference between the steps and the treads, with the treads being higher than the steps. Therefore, if passengers on the escalator are not paying attention and forget to lift their feet when they reach the exit (e.g., chatting, playing on their phones), they are likely to trip on the treads and fall forward. Passengers behind them are then continuously transported forward by the escalator, which can easily cause a stampede. In this case, when the present invention is working, if a passenger forgets to lift their feet when they reach the escalator exit, their feet will push forward against the monitoring board. The monitoring board will push the guide rod into the guide hole, so that contact point two contacts contact point one. By setting the processor program, after contact point one and contact point two are connected, the alarm can emit an alarm signal and continue for a period of time, reminding the management personnel to check on the fallen passenger and warning the passengers behind to pay attention, thus improving the safety of the escalator.

[0007] Preferably, a first touch ring is fixedly connected to the inner side of one of the guide holes; a second touch ring is fixedly connected to the outer side of the guide rod near the first touch ring; the first and second touch rings are connected to the escalator via a processor; when the monitoring board is in the reset state, the first touch ring and the second touch ring are in contact, and the escalator maintains normal operation; when the monitoring board pushes the guide rod into the guide hole, the first and second touch rings are disengaged; by setting the processor program, the escalator can automatically stop running for a period of time after the first and second touch rings are disconnected, thereby stopping the forward transport of passengers, preventing trampling on previously fallen passengers, and reducing the probability of trampling accidents.

[0008] Preferably, a set of anti-slip grooves are evenly distributed on the upper side of the step; an installation groove is provided on the lower side of the tread; a set of scrapers are evenly distributed inside the installation groove; the scrapers correspond one-to-one with the anti-slip grooves, and the lower end of the scrapers extends into the anti-slip groove; by setting anti-slip grooves, the anti-slip performance of the steps can be improved. After long-term use, dust and other debris from passengers' feet are easily retained inside the anti-slip grooves. By setting multiple scrapers, when the steps move to the lower side of the tread, the scrapers can scrape away the debris inside the anti-slip grooves, realizing the self-cleaning function of the anti-slip grooves, eliminating the need for manual cleaning and improving the automation level of the escalator.

[0009] Preferably, a set of suction heads are evenly distributed inside the mounting groove; each suction head corresponds to a scraper blade, and the suction head is located above the scraper blade; the suction head is connected to a negative pressure device through a pipeline; by setting multiple suction heads, the negative pressure device is activated when the escalator is working, and negative pressure is generated at the suction heads, so that after the scraper blade scrapes away the debris inside the anti-slip groove, the suction head can suck away the debris, preventing the debris from accumulating on one side of the scraper blade after being scraped away, and further improving the self-cleaning effect of the anti-slip groove.

[0010] Preferably, a circular groove is provided on the underside of the pedal, and the circular groove is located between the mounting groove and the monitoring board; a rotating shaft is rotatably connected inside the circular groove; a rotating cylinder is fixedly connected to the outside of the rotating shaft; a set of protrusions are evenly distributed on the surface of the rotating cylinder, and the protrusions are set as rings; the protrusions correspond one-to-one with the anti-slip grooves, and the protrusions extend into the anti-slip grooves; both the rotating cylinder and the protrusions are made of water-absorbing material, and both the rotating cylinder and the protrusions absorb moisture; when the step passes under the pedal, it will drive the rotating shaft and the rotating cylinder to rotate, causing the protrusions to roll inside the anti-slip grooves, and then the protrusions will spread the moisture inside the anti-slip grooves, thereby softening the debris inside the anti-slip grooves. Afterwards, the debris is scraped by the scraper, avoiding the problem that some debris is more firmly adhered (such as hardened soil, chewing gum, etc.) and that the scraper is difficult to scrape off, thus further improving the cleaning efficiency of the scraper on the anti-slip grooves.

[0011] Preferably, a fixing ring is fixedly connected to the inside of the circular groove near both ends of the rotating shaft; a fixing cylinder is fixedly connected to the surface of the fixing ring, and the rotating cylinder passes through the fixing ring and the fixing cylinder and is rotatably connected to them; a water storage tank is fixedly connected to the surface of the escalator below the fixing ring, and the water storage tank is filled with clean water; a water guide strip is fixedly connected to the lower side of the fixing cylinder, and the lower end of the water guide strip extends into the inside of the water storage tank; both the fixing cylinder and the water guide strip are made of water-absorbing material; the water in the water storage tank is transferred to the fixing cylinder through the water guide strip, so that the inside of the fixing cylinder is filled with water. Since the rotating cylinder and the fixing cylinder are in contact with each other and rotatably connected, the rotating cylinder can absorb water from the surface of the fixing cylinder during the rotation of the rotating shaft and the rotating cylinder, and then the water is transferred to each protrusion through the rotating cylinder. Therefore, as long as there is water in the water storage tank, the protrusions can work continuously, thereby continuously applying water to the inside of the anti-slip groove to soften the debris.

[0012] Preferably, a movable ring is fixedly connected to the end of the fixed cylinder away from the fixed ring, and the rotating cylinder passes through the movable ring and is rotatably connected to it; a pressure block is fixedly connected to the side of the step, and the surface of the pressure block is provided with an arc surface; during the movement of the step, the pressure block can contact the movable ring; when the step moves to the underside of the pedal, the arc surface of the pressure block squeezes the movable ring and pushes the movable ring towards the fixed ring, and then the movable ring squeezes the fixed cylinder, squeezing out the water inside the fixed cylinder. After the water is squeezed out, it fully contacts the rotating cylinder, thereby improving the efficiency of the rotating cylinder in absorbing water from the surface of the fixed cylinder and increasing the speed of water transmission to the protrusion. When the pressure block passes the movable ring, the movable ring and the fixed cylinder reset, and the water guide strip then transmits the water back to the inside of the fixed cylinder.

[0013] Preferably, an elastic corrugated pipe is fixedly connected between the fixed ring and the movable ring, and the fixed cylinder is located inside the elastic corrugated pipe; the water guide strip passes through the elastic corrugated pipe; the water guide strip is wrapped with a flexible hose, and the flexible hose is connected to the corrugated pipe; by setting the corrugated pipe and the flexible hose to cover the fixed cylinder and the water guide strip respectively, on the one hand, external dust can be prevented from entering the fixed cylinder and the water guide strip, preventing the fixed cylinder and the water guide strip from being blocked; on the other hand, when the fixed cylinder is squeezed, the squeezed water can be kept inside the corrugated pipe and the flexible hose, avoiding the problem of water splashing to the surroundings, and after the subsequent pressure block passes over the movable ring, the elasticity of the corrugated pipe can push the movable ring to reset smoothly, improving the reset efficiency of the movable ring.

[0014] Preferably, a pair of elastic membranes are fixedly connected between the pedal and the monitoring board, and the guide rod and the spring are both located between the pair of elastic membranes. By setting a pair of elastic membranes to seal the gap between the pedal and the monitoring board, it is possible to prevent debris from entering the gap and clogging the guide hole and the spring. It can also prevent moisture or humid air from entering the guide hole and causing damage or short circuits to electrical components.

[0015] Preferably, an arc-shaped spring sheet is provided on the lower side of the top elastic membrane, and the two ends of the arc-shaped spring sheet are fixedly connected to the pedal and the monitoring board respectively; the concave surface of the arc-shaped spring sheet faces the spring; by providing the arc-shaped spring sheet, when the monitoring board moves toward the pedal, it will squeeze the arc-shaped spring sheet, thereby deforming and bending the arc-shaped spring sheet and pushing the elastic membrane upward, so that the elastic membrane bulges upward, avoiding the problem of people being pinched by the gap between the monitoring board and the pedal.

[0016] The beneficial effects of this invention are as follows:

[0017] 1. The safety monitoring and alarm device of the present invention, if a passenger forgets to lift their foot when reaching the exit of the escalator, the passenger's foot will push forward against the monitoring plate. The monitoring plate will push the guide rod into the guide hole, so that contact point two contacts contact point one. By setting the processor program, after contact point one and contact point two are connected, the alarm can emit an alarm signal and continue for a period of time, reminding the management personnel to check on the fallen passenger and alerting the passengers behind to concentrate, thereby improving the safety of the escalator.

[0018] 2. In the safety monitoring and alarm device of the present invention, when the monitoring board is in the reset state, contact ring one and contact ring two are in contact, and the escalator maintains normal operation. When the monitoring board pushes the guide rod into the guide hole, contact ring one and contact ring two are disengaged. By setting the processor program, the escalator can automatically stop running for a period of time after contact ring one and contact ring two are disconnected, thereby stopping the forward transport of passengers, preventing trampling of previously fallen passengers, and reducing the probability of trampling accidents.

Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] Example 1

[0030] like Figures 1 to 6 As shown in the embodiment of the present invention, a safety monitoring and alarm device includes an escalator 1; a set of steps 2 are provided on the surface of the escalator 1; a footboard 3 is fixedly connected to the bottom of the escalator 1, and the footboard 3 is located on the upper side of the steps 2; an alarm 4 is fixedly connected to the surface of the escalator 1; a groove is formed on the side of the footboard 3 near the escalator 1; a monitoring plate 5 is provided inside the groove; a set of springs 6 are evenly distributed between the monitoring plate 5 and the footboard 3; a set of guide holes 7 are evenly formed on the side of the footboard 3 near the monitoring plate 5; a guide rod 8 is slidably connected inside the guide hole 7, and one end of the guide rod 8 extending outside the guide hole 7 is fixedly connected to the monitoring plate 5; a contact point 9 is fixedly connected to the end of one of the guide holes 7, and a contact point 10 is fixedly connected to the end of the guide rod 8 corresponding to the contact point 9; the contact point 9 and the contact point 10 are connected to the alarm 4 through a processor. At the exit of escalator 1, there is usually a height difference between the steps 2 and the treads 3, with the treads 3 being higher than the steps 2. Therefore, if passengers on the escalator are not paying attention and forget to lift their feet when they reach the exit (e.g., while chatting or playing on their phones), they are likely to trip over the treads 3 and fall forward. Passengers behind them are then continuously transported forward by escalator 1, which can easily cause a stampede. In this case, when the present invention is working, if a passenger forgets to lift their feet when they reach the exit of escalator 1, their feet will push forward against the monitoring board 5. The monitoring board 5 will push the guide rod 8 into the guide hole 7, causing contact point 2 10 to contact contact point 1 9. By setting the processor program, after contact point 1 9 and contact point 2 10 are connected, the alarm 4 can issue an alarm signal and continue for a period of time, reminding the management personnel to check on the fallen passenger and warning the passengers behind to pay attention, thus improving the safety of escalator 1.

[0031] One of the guide holes 7 is fixedly connected to a first contact ring 11; a second contact ring 12 is fixedly connected to the outer side of the guide rod 8 near the first contact ring 11; the first contact ring 11 and the second contact ring 12 are connected to the escalator 1 through a processor; when the monitoring board 5 is in the reset state, the first contact ring 11 and the second contact ring 12 are in contact, and the escalator 1 maintains normal operation. When the monitoring board 5 pushes the guide rod 8 into the guide hole 7, the first contact ring 11 and the second contact ring 12 are misaligned. By setting the program of the processor, the escalator 1 can automatically stop running for a period of time after the first contact 9 and the second contact 10 are disconnected, thereby stopping the forward transport of passengers, preventing the trampling of previously fallen passengers, and reducing the probability of trampling accidents.

[0032] A set of anti-slip grooves 13 are evenly distributed on the upper side of the step 2; an installation groove 14 is provided on the lower side of the tread 3; a set of scraper blades 15 are evenly distributed inside the installation groove 14; the scraper blades 15 correspond one-to-one with the anti-slip grooves 13, and the lower end of the scraper blades 15 extends into the anti-slip grooves 13; by setting the anti-slip grooves 13, the anti-slip performance of the step 2 can be improved. After long-term use, dust and other debris from passengers' feet are easily retained inside the anti-slip grooves 13. By setting multiple scraper blades 15, when the step 2 moves to the lower side of the tread 3, the scraper blades 15 can scrape away the debris inside the anti-slip grooves 13, realizing the self-cleaning function of the anti-slip grooves 13, eliminating the need for manual cleaning and improving the automation level of the escalator.

[0033] A set of suction heads 16 are evenly distributed inside the mounting groove 14; each suction head 16 corresponds to a scraper 15, and the suction head 16 is located above the scraper 15; the suction head 16 is connected to a negative pressure device through a pipeline; by setting multiple suction heads 16, the negative pressure device is activated when the escalator is working, and negative pressure is generated at the suction head 16, so that after the scraper 15 scrapes away the debris inside the anti-slip groove 13, the suction head 16 can suck away the debris, preventing the debris from accumulating on one side of the scraper 15 after being scraped away, and further improving the self-cleaning effect of the anti-slip groove 13.

[0034] A circular groove 17 is provided on the lower side of the pedal 3, and the circular groove 17 is located between the mounting groove 14 and the monitoring board 5; a rotating shaft 18 is rotatably connected inside the circular groove 17; a rotating cylinder 19 is fixedly connected to the outside of the rotating shaft 18; a set of protrusions 20 are evenly distributed on the surface of the rotating cylinder 19, and the protrusions 20 are arranged in a ring shape; the protrusions 20 correspond one-to-one with the anti-slip grooves 13, and the protrusions 20 extend into the anti-slip grooves 13; both the rotating cylinder 19 and the protrusions 20 are made of water-absorbing material, and the interiors of the rotating cylinder 19 and the protrusions 20 are made of water-absorbing material. Both absorb moisture; when step 2 passes under the pedal 3, it drives the rotating shaft 18 and the rotating drum 19 to rotate, causing the protrusion 20 to roll inside the anti-slip groove 13. The protrusion 20 then applies the moisture inside to the inside of the anti-slip groove 13, thereby softening the debris inside the anti-slip groove 13. After the debris passes through the scraper 15, it avoids the problem that some debris is more firmly adhered (such as hardened soil, chewing gum, etc.) and that the scraper 15 has difficulty scraping it off smoothly, thus further improving the cleaning efficiency of the scraper 15 on the anti-slip groove 13.

[0035] A fixing ring 21 is fixedly connected to the inside of the circular groove 17 near both ends of the rotating shaft 18; a fixing cylinder 22 is fixedly connected to the surface of the fixing ring 21, and the rotating cylinder 19 passes through the fixing ring 21 and the fixing cylinder 22 and is rotatably connected to them; a water storage tank 23 is fixedly connected to the surface of the escalator 1 below the fixing ring 21, and the water storage tank 23 is filled with clean water; a water guide strip 24 is fixedly connected to the lower side of the fixing cylinder 22, and the lower end of the water guide strip 24 extends into the interior of the water storage tank 23; both the fixing cylinder 22 and the water guide strip 24 are made of absorbent material. The water is transferred from the water tank 23 to the fixed cylinder 22 through the water guide strip 24, so that the fixed cylinder 22 is filled with water. Since the rotating cylinder 19 is in contact with the fixed cylinder 22 and is rotatably connected, the rotating cylinder 19 can absorb water from the surface of the fixed cylinder 22 during the rotation of the rotating shaft 18 and the rotating cylinder 19. Then the water is transferred to each protrusion 20 through the rotating cylinder 19. Therefore, as long as there is water in the water tank 23, the protrusion 20 can work continuously, thereby continuously applying water to the inside of the anti-slip groove 13 to soften the impurities.

[0036] The fixed cylinder 22 is fixedly connected to a movable ring 25 at the end away from the fixed ring 21, and the rotating cylinder 19 passes through the movable ring 25 and is rotatably connected to it; a pressure block 26 is fixedly connected to the side of the step 2, and the surface of the pressure block 26 is provided with an arc surface; during the movement of the step 2, the pressure block 26 can contact the movable ring 25; when the step 2 moves to the underside of the pedal 3, the arc surface of the pressure block 26 squeezes the movable ring 25 and pushes the movable ring 25 toward the fixed ring 21, and then the movable ring 25 squeezes the fixed cylinder 22, squeezing out the water inside the fixed cylinder 22. After the water is squeezed out, it fully contacts the rotating cylinder 19, thereby improving the efficiency of the rotating cylinder 19 in absorbing water from the surface of the fixed cylinder 22 and increasing the speed of water transmission to the protrusion 20. When the pressure block 26 passes the movable ring 25, the movable ring 25 and the fixed cylinder 22 reset, and the water guide strip 24 then transmits the water back to the inside of the fixed cylinder 22.

[0037] A flexible corrugated pipe 27 is fixedly connected between the fixed ring 21 and the movable ring 25, and the fixed cylinder 22 is located inside the flexible corrugated pipe 27; the water guide strip 24 passes through the flexible corrugated pipe 27; the water guide strip 24 is wrapped with a flexible hose 28, and the flexible hose 28 is connected to the corrugated pipe 27; by setting the corrugated pipe 27 and the flexible hose 28 to cover the fixed cylinder 22 and the water guide strip 24 respectively, on the one hand, it can prevent external dust from entering the fixed cylinder 22 and the water guide strip 24, and prevent the fixed cylinder 22 and the water guide strip 24 from being blocked; on the other hand, when the fixed cylinder 22 is squeezed, the squeezed water can be kept inside the corrugated pipe 27 and the flexible hose 28, avoiding the problem of water splashing to all sides, and after the subsequent pressure block 26 passes over the movable ring 25, the elasticity of the corrugated pipe 27 can push the movable ring 25 to reset smoothly, improving the reset efficiency of the movable ring 25.

[0038] Example 2

[0039] like Figure 7 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: a pair of elastic membranes 29 are fixedly connected between the pedal 3 and the monitoring board 5, and the guide rod 8 and the spring 6 are both located between the pair of elastic membranes 29; by setting a pair of elastic membranes 29 to seal the gap between the pedal 3 and the monitoring board 5, it is possible to prevent debris from entering this gap and blocking the guide hole 7 and the spring 6, and it is also possible to prevent moisture or humid air from entering the guide hole 7 and causing damage to electrical components or short circuits.

[0040] An arc-shaped spring sheet 30 is provided on the lower side of an elastic membrane 29 at the top, and the two ends of the arc-shaped spring sheet 30 are fixedly connected to the pedal 3 and the monitoring plate 5 respectively; the concave surface of the arc-shaped spring sheet 30 faces the spring 6; by setting the arc-shaped spring sheet 30, when the monitoring plate 5 moves toward the pedal 3, it will squeeze the arc-shaped spring sheet 30, thereby deforming and bending the arc-shaped spring sheet 30 and pushing the elastic membrane 29 upward, so that the elastic membrane 29 bulges upward, avoiding the problem of people being pinched by the gap between the monitoring plate 5 and the pedal 3.

[0041] Working Principle: When the escalator is in operation, if a passenger forgets to lift their foot when reaching the exit of escalator 1, their foot will push forward against the monitoring board 5. The monitoring board 5 will push the guide rod 8 into the guide hole 7, causing contact point 2 10 to contact contact point 1 9. Through the programmed processor, after contact point 1 9 and contact point 2 10 are connected, the alarm 4 will emit an alarm signal and continue for a period of time, reminding management personnel to check on the fallen passenger and alerting passengers behind to pay attention, thus improving the safety of escalator 1. When the monitoring board 5 is in the reset state, contact ring 11 and contact ring 2 12 are in contact, and escalator 1 maintains normal operation. When the monitoring board 5 pushes the guide rod 8 into the guide hole 7... The touch ring 11 and touch ring 2 12 are staggered. By setting the processor program, the escalator 1 can automatically stop running for a period of time after the contact 1 9 and contact 2 10 are disconnected, thereby stopping the forward transport of passengers and preventing them from being trampled on. This reduces the probability of trampling accidents. By setting the anti-slip groove 13, the anti-slip performance of the steps 2 can be improved. After long-term use, dust and other debris from passengers' feet can easily remain inside the anti-slip groove 13. By setting multiple scrapers 15, when the steps 2 move to the underside of the tread 3, the scrapers 15 can scrape away the debris inside the anti-slip groove 13, realizing the self-cleaning function of the anti-slip groove 13. This eliminates the need for manual cleaning and improves the automation level of the escalator. By setting multiple suction heads 16, the negative pressure device is activated when the escalator is working, and negative pressure is generated at the suction heads 16. This causes the scraper 15 to scrape away debris inside the anti-slip groove 13, and the suction heads 16 can then suck up the debris, preventing it from accumulating on one side of the scraper 15, further improving the self-cleaning effect of the anti-slip groove 13. When the step 2 passes under the tread 3, it drives the rotating shaft 18 and the rotating drum 19 to rotate, causing the protrusion 20 to roll inside the anti-slip groove 13. The protrusion 20 then applies moisture to the inside of the anti-slip groove 13, softening the debris inside. Afterward, the debris passes through the scraper 15, preventing some debris from adhering firmly (such as hardened mud). (Soil, chewing gum, etc.), which makes it difficult for the scraper 15 to scrape them off smoothly, further improving the cleaning efficiency of the scraper 15 on the anti-slip groove 13; the water guide strip 24 transmits the clean water inside the water storage tank 23 to the fixed cylinder 22, so that the fixed cylinder 22 is filled with water. Since the rotating cylinder 19 is in contact with the fixed cylinder 22 and rotates, the rotating cylinder 19 can absorb water from the surface of the fixed cylinder 22 during the rotation of the rotating shaft 18 and the rotating cylinder 19. Then the water is transmitted to each protrusion 20 through the rotating cylinder 19. Therefore, as long as there is water inside the water storage tank 23, the protrusion 20 can work continuously, thereby continuously applying water to the inside of the anti-slip groove 13 to soften the debris;When step 2 moves to the underside of tread 3, the arc surface of pressure block 26 presses against movable ring 25 and pushes movable ring 25 towards fixed ring 21. Movable ring 25 then presses against fixed cylinder 22, squeezing out water from inside fixed cylinder 22. The squeezed-out water then fully contacts rotating cylinder 19, thereby increasing the efficiency of water absorption from the surface of fixed cylinder 22 by rotating cylinder 19 and increasing the speed of water transfer to protrusion 20. When pressure block 26 passes movable ring 25, movable ring 25 and fixed cylinder 22 return to their original positions, and water guide strip 24 then re-transfers the water into the fixed cylinder 22. By using corrugated pipe 27 and flexible hose 28 to cover fixed cylinder 22 and water guide strip 24 respectively, external dust can be prevented from entering the fixed cylinder 22 and water guide strip 24, preventing blockage. Furthermore, when fixed cylinder 22 is squeezed... The squeezed-out water can be retained inside the bellows 27 and hose 28, preventing water from splashing outwards. Furthermore, after the pressure block 26 passes the movable ring 25, the elasticity of the bellows 27 can push the movable ring 25 back to its original position, improving the reset efficiency of the movable ring 25. By setting a pair of elastic membranes 29 to seal the gap between the pedal 3 and the monitoring plate 5, it can prevent debris from entering this gap and clogging the guide hole 7 and spring 6. It can also prevent water or humid air from entering the guide hole 7 and causing damage or short circuits to electrical components. By setting an arc-shaped spring 30, when the monitoring plate 5 moves towards the pedal 3, it will squeeze the arc-shaped spring 30, causing it to deform and bend, pushing the elastic membrane 29 upwards, making the elastic membrane 29 bulge upwards, preventing injury from being trapped in the gap between the monitoring plate 5 and the pedal 3.
