Description

Technical Field

[0001] This application belongs to the field of elevator technology, specifically relating to auxiliary pedal keys for elevators. Background Technology

[0002] From the perspective of everyday elevator usage, when people are carrying heavy items, such as deliverymen delivering packages, shopping for large quantities of household goods, moving office supplies, or pushing strollers, it is difficult to have both hands free to accurately operate the elevator buttons. This not only reduces travel efficiency but may also cause people to press the wrong floor in their haste, affecting their subsequent journey.

[0003] During flu season, traditional elevator buttons, frequently touched by numerous passengers, become high-risk areas for the spread of bacteria and viruses. Studies have shown that in crowded places like elevators, each square centimeter of button surface can carry thousands of bacteria and viruses, such as E. coli, Staphylococcus aureus, and various respiratory viruses. When healthy individuals touch contaminated buttons and then touch their mouths, noses, or eyes, cross-infection is highly likely. Summary of the Invention

[0028] Example 1

[0029] like Figures 1 to 2 As shown, this application provides an auxiliary pedal keypad for elevators, including a base 1 set on the ground. From left to right, a trigger pressure switch 2, a tens digit signal switch 3, and a units digit signal switch are respectively arranged on the top of the base 1. The trigger pressure switch 2 is provided with an anti-accidental contact shell 6. The tens digit signal switch 3 is a single-point signal switch that sends a click signal. The units digit signal switch is a travel switch that sends a travel value signal. A controller is provided on the base 1 that is electrically connected to the trigger pressure switch 2, the tens digit signal switch 3, and the units digit signal switch. The controller is electrically connected to the car button assembly.

[0030] The trigger pressure switch 2 is used to turn on the tens digit signal switch 3 and the units digit signal switch to avoid frequent triggering of the floor signal. The tens digit signal switch 3 is a single-point signal switch that determines the specific value of the tens digit of the floor by counting the number of signals. The units digit signal switch is a travel switch that sends a travel value signal and determines the value of the units digit of the floor based on the travel value signal. This is suitable for situations where the tens digit value is small and the units digit value is large, thus perfectly realizing the effective expression of the floor signal.

[0031] Specifically, after the user triggers the pressure switch 2 with their foot, the controller activates the tens digit signal switch 3 and the units digit signal switch within a preset time period T. The user first triggers the tens digit signal switch 3 with their foot, and the number of clicks represents the value of the tens digit of the floor number. For example, if the target floor is the 13th floor, the user only needs to click the tens digit signal switch once. Then, the user manipulates the units digit signal switch with their foot so that its trigger reaches the preset position. The units digit signal switch sends the corresponding travel information to the controller. The controller obtains the value of the units digit (0-9) of the corresponding floor button according to the preset comparison relationship.

[0032] Specifically, the anti-accidental contact shell 6 is a shell that is open to the outside from the rear. An installation block is provided inside the anti-accidental contact shell 6. The trigger pressure switch 2 is located on the rear end face of the installation block, and the trigger pressure switch 2 is located entirely in the inner cavity of the anti-accidental contact shell 6. The anti-accidental contact shell 6 is used to protect the trigger pressure switch 2 and prevent it from being accidentally stepped on, thus wasting energy.

[0033] Preferably, the front upper and lower end faces of the anti-accidental contact shell 6 are arc-shaped to reduce the space occupied in the car.

[0034] Preferably, the trigger part of the ten-position signal switch 3 is a rectangular structure facing upwards, which is convenient for the user to step on.

[0035] Specifically, the unit digit signal switch includes a mounting base 4 disposed on the top of the base 1. A semi-circular indicator groove 41 is provided on the front side of the top of the mounting base 4. A linkage rod 9 is rotatably disposed at the center of the semi-circular structure of the indicator groove 41. A rotating pedal 5 is disposed on the top of the linkage rod 9. A pointer 8 is disposed on the side of the linkage rod 9. The pointer 8 extends horizontally and is located inside the indicator groove 41. A scale for marking the number of floors is provided on the semi-circular frame of the indicator groove 41. A torsion spring and an angular displacement sensor are disposed at the connection between the linkage rod 9 and the bottom wall of the indicator groove 41. The angular displacement sensor is electrically connected to the controller.

[0036] like Figure 1 and Figure 2As shown, assuming that when the rotating pedal 5 is in the initial position, the pointer 8 points to the left, the left side is set as the initial position, and the right side is set as the floor scale representing the number 9. Between the two, along the semi-circular edge of the indicator groove 41, the floor unit value scale from 0 to 8 is evenly set. The user controls the rotating pedal 5 to rotate with his foot, which drives the pointer 8 to rotate. When the pointer 8 stays at a certain position for a preset time T1, the controller records the angular displacement reading transmitted by the angular displacement sensor, and determines the corresponding number according to the preset reading reference table, thereby determining the unit value of the floor.

[0037] Preferably, the top of the indicator groove 41 is covered with a transparent glass cover to protect the pointer 8.

[0038] Furthermore, the rotating pedal 5 includes a pedal block with a pedal groove on the top and rear that communicates with the outside. The user inserts their foot into the pedal groove and rotates their ankle to control the rotating pedal 5.

[0039] Preferably, the mounting base 4 has an arc-shaped structure with an arc angle greater than 180 degrees, which is beneficial for the installation of the linkage rod 9 and the rotating pedal 5.

[0040] Preferably, it also includes a display 7 electrically connected to the controller, used to display the floor value output by the user using this application. If an incorrect floor is output, the user can use their foot to trigger the pressure switch 2 to re-output the floor value.

[0041] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
