Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0035] like Figure 1-Figure 5 As shown, a platform elevator safety touch panel includes: a car bottom body 1, a touch panel assembly 2, and a micro switch 3.

[0036] The touch panel assembly 2 is arranged at the edge of the car bottom body 1 , and the touch panel assembly 2 includes an elevator bottom plate 21 and a safety pedal 22 . The safety pedal 22 is movably connected to the elevator bottom plate 21 and can be close to or away from the elevator bottom plate 21 .

[0037] The micro switch 3 is connected to one of the elevator floor 21 and the safety pedal 22 , and when the safety pedal 22 is close to the elevator floor 21 , the micro switch 3 can contact the other of the elevator floor 21 and the safety pedal 22 .

[0038] In this embodiment, when the platform elevator is in operation, the user approaches the edge of the car base body 1 or accidentally touches the shaft wall, and then touches the safety pedal 22. The safety pedal 22 sinks and approaches the elevator floor 21, so that the micro switch 3 arranged between the elevator floor 21 and the safety pedal 22 is triggered, thereby transmitting an electrical signal to the controller, thereby stopping the car base body 1 from continuing to operate.

[0039] like Figure 1-Figure 5As shown, based on the above embodiment, a return spring 4 is further included, one end of the return spring 4 is connected to or in contact with the elevator bottom plate 21 , and the other end of the return spring 4 is connected to or in contact with the safety pedal 22 .

[0040] In this embodiment, when the safety pedal 22 approaches the elevator floor 21, the return spring 4 is compressed and deformed. When the force applied on the safety pedal 22 disappears, the safety pedal 22 moves away from the elevator floor 21 again under the action of the return spring 4.

[0041] like Figure 1-Figure 5 As shown, on the basis of the above embodiment, it also includes a positioning member 5, which is arranged between the elevator floor 21 and the safety pedal 22, and the positioning member 5 is connected to one of the elevator floor 21 and the safety pedal 22, and the positioning member 5 is slidably connected to the other of the elevator floor 21 and the safety pedal 22.

[0042] Specifically, when the positioning member 5 is connected to one of the elevator bottom plate 21 and the safety pedal 22, the other of the elevator bottom plate 21 and the safety pedal 22 is provided with a groove, and the positioning member 5 is slidably connected thereto.

[0043] In this embodiment, the positioning member 5 is located between the elevator bottom plate 21 and the safety pedal 22. When the safety pedal 22 approaches the elevator bottom plate 21, the other end of the positioning member 5 slides in the provided groove to play a guiding role.

[0044] like Figure 1-Figure 5 As shown, on the basis of the above embodiment, the return spring 4 is sleeved on the positioning member 5 .

[0045] In this embodiment, the return spring 4 is sleeved on the fixing member to prevent the return spring 4 from coming out from between the elevator bottom plate 21 and the safety pedal 22 .

[0046] like Figure 1-Figure 5 As shown, on the basis of the above embodiment, the elevator floor 21 is provided with a first through hole 211, one end of the positioning member 5 is connected to the safety pedal 22, and the other end of the positioning member 5 passes through the first through hole 211 so that the positioning member 5 can be slidably connected to the elevator floor 21.

[0047] In this embodiment, the positioning member 5 is located between the elevator floor 21 and the safety pedal 22. One end of the positioning member 5 is connected to the safety pedal 22, and the other end passes through the first through hole 211 and is slidably connected to the elevator floor 21, playing a guiding role.

[0048] like Figure 1-Figure 5As shown, on the basis of the above embodiment, the positioning member 5 passes through the first through hole 211 and forms an extension portion, and the extension portion is provided with a limiting portion, and the limiting portion is larger than the first through hole 211.

[0049] In this embodiment, when the positioning member 5 follows the safety pedal 22 and rises under the action of the return spring 4, the positioning member 5 cannot continue to rise because the limiting portion is larger than the first through hole 211. At this time, the limiting portion contacts the elevator floor 21, thereby preventing the positioning member 5 from escaping from the first through hole 211, thereby limiting the maximum distance between the safety pedal 22 and the elevator floor 21.

[0050] like Figure 1-Figure 5 As shown, on the basis of the above embodiment, the limiting portion is configured as a limiting member 6, and the limiting member 6 is detachably connected to the extending portion.

[0051] In this embodiment, the limiting member 6 can be detachably connected to the extension portion by means of a thread or other connection method.

[0052] like Figure 1-Figure 5 As shown, on the basis of the above embodiment, the extension portion is provided with a second through hole 51 , the limiting portion is provided as a limiting member 6 , and the limiting member 6 passes through the second through hole 51 .

[0053] In this embodiment, the limiter 6 passes through the second through hole 51 . When the safety pedal 22 is away from the elevator base, the limiter 6 is larger than the first through hole 211 and contacts the elevator bottom plate 21 , thereby preventing the positioning member 5 from escaping from the first through hole 211 .

[0054] like Figure 1-Figure 5 As shown, based on the above embodiment, a stopper is further included, and the stopper is connected to one of the elevator floor plate 21 and the safety pedal 22, and the stopper can contact the other of the elevator floor plate 21 and the safety pedal 22.

[0055] Specifically, the stopper is welded to one of the elevator floor plate 21 and the safety pedal 22 . At this time, when the safety pedal 22 approaches the elevator floor plate 21 , the stopper may contact the other of the elevator floor plate 21 and the safety pedal 22 .

[0056] Alternatively, the stopper is disposed between the elevator floor 21 and the safety pedal 22 , and contacts the elevator floor 21 and the safety pedal 22 when the safety pedal 22 approaches the elevator floor 21 .

[0057] In this embodiment, during the movement of the safety pedal 22 , the stopper contacts the safety pedal 22 and the elevator bottom plate 21 , thereby limiting the maximum sinking distance of the safety pedal 22 .

[0058] like Figure 1-Figure 5 As shown, on the basis of the above embodiment, the stopper is configured as a stop ring 7 , and the stop ring 7 is sleeved on the positioning member 5 .

[0059] In this embodiment, the stop ring 7 is sleeved in the positioning member 5 and contacts the safety pedal 22 when it approaches the elevator bottom plate 21, thereby limiting the maximum sinking depth of the safety pedal 22 and protecting the micro switch 3 from being crushed.
