[0021] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0022] Example:

[0023] like Figures 1-3 As shown, an elevator with a pressure-sensitive floor includes a car floor plate 1, a piezoelectric sensing plate 2 fixedly connected to the top of the car floor plate 1, a connecting base plate 3 fixedly connected to the top of the piezoelectric sensing plate 2, a connecting mounting ring 4 fixedly connected to the bottom of the car floor plate 1, a first motor 5 fixedly connected to the middle of the bottom end of the car floor plate 1, a movable limiting mechanism 6 movably connected to the inner side of the bottom end of the connecting mounting ring 4, the output end of the first motor 5 being connected and fixedly connected to the top of the movable limiting mechanism 6, a connecting adjustment mechanism 7 being provided at the bottom of the movable limiting mechanism 6, and a connecting counterweight mechanism 8 being bolted to the output end of the connecting adjustment mechanism 7.

[0024] The working principle of the above technical solution is as follows:

[0025] During use, the weight distribution on the top of the connecting base plate 3 can be detected by the piezoelectric sensing plate 2. Then, under the action of the connecting mounting ring 4, the first motor 5, the movable limit mechanism 6 and the connecting adjustment mechanism 7, the position of the connecting counterweight mechanism 8 can be adjusted so that the connecting counterweight mechanism 8 moves to a position with less weight, thereby balancing the weight and making the car stable to use, avoiding shaking of the car during operation, and making operation convenient.

[0026] In another embodiment, such as Figure 3 As shown, the movable limiting mechanism 6 includes a connecting limiting top ring 10 located inside the connecting mounting ring 4. The bottom of the connecting limiting top ring 10 is fixedly connected to a movable mounting ring 9, and the bottom end of the movable mounting ring 9 is provided with a connecting guide groove 11.

[0027] When the first motor 5 drives the movable mounting ring 9, it can drive the movable mounting ring 9 and the connecting limit top ring 10 to rotate, thereby driving the connecting adjustment mechanism 7 to rotate. At the same time, it allows the connecting limit top ring 10 to rotate inside the connecting mounting ring 4, making operation convenient.

[0028] In another embodiment, such as Figure 3 As shown, the connecting adjustment mechanism 7 includes a fixed support block 12 symmetrically located at the bottom of the movable mounting ring 9. A connecting threaded rod 14 is movably connected inside the fixed support block 12. One end of the connecting threaded rod 14 is fixedly connected to a limit end plate 15, and the other end of the connecting threaded rod 14 is fixedly connected to a second motor 13. The second motor 13 is connected and fixed to the movable mounting ring 9. A movable connecting block 16 is threadedly connected to the outer surface of the connecting threaded rod 14.

[0029] When the second motor 13 is driven, it drives the connecting threaded rod 14 to rotate, so that the movable connecting block 16 can move on the outer side of the connecting threaded rod 14 and the inner side of the connecting guide groove 11, thereby enabling the position of the connecting counterweight mechanism 8 to be moved and adjusted, which is convenient to operate.

[0030] In another embodiment, such as Figure 3 As shown, the connecting counterweight mechanism 8 includes a connecting mounting block 17 located inside the bottom end of the movable connecting block 16, and a counterweight base block 18 is fixedly connected to the bottom end of the connecting mounting block 17.

[0031] The connecting mounting block 17 can be easily inserted into the inner side of the bottom of the movable connecting block 16 and fixed by bolts, so that the counterweight base block 18 can be installed and used, making the operation convenient.

[0032] In another embodiment, such as Figure 3 As shown, the cross-sectional shape of the connecting limiting top ring 10 is T-shaped, and the outer surface of the connecting limiting top ring 10 slides and fits against the inner surface of the connecting mounting ring 4.

[0033] When the movable mounting ring 9 rotates, it can drive the connecting limiting top ring 10 to rotate inside the connecting mounting ring 4, making operation convenient.

[0034] In another embodiment, such as Figure 3 As shown, the outer side of the upper surface of the movable connecting block 16 slides and fits against the inner side of the connecting guide groove 11.

[0035] The movable connecting block 16 can move stably inside the connecting guide groove 11, making operation convenient.

[0036] In another embodiment, such as Figure 3 As shown, the cross-sectional shape of the connecting mounting block 17 is T-shaped, and the outer side of the top surface of the connecting mounting block 17 slides and fits against the inner side of the bottom end of the movable connecting block 16.

[0037] The mounting block 17 can be stably locked inside the bottom of the movable connecting block 16, thus enabling a stable connection and convenient operation.

[0038] The working principle of this utility model is as follows: During use, when the weight distribution on the top of the connecting base plate 3 is uneven, the piezoelectric sensing plate 2 can detect the weight distribution. Then, the elevator controller controls the first motor 5 and the connecting adjustment mechanism 7, so that the first motor 5 drives the movable mounting ring 9, causing the connecting limit top ring 10 to rotate inside the connecting mounting ring 4. At the same time, the direction of the connecting adjustment mechanism 7 is adjusted. Then, the second motor 13 drives the connecting threaded rod 14, so that when the connecting threaded rod 14 rotates, the movable connecting block 16 can move on the outer side of the surface of the connecting threaded rod 14 and the inner side of the connecting guide groove 11, causing the connecting mounting block 17 and the counterweight base block 18 to move. This moves the counterweight base block 18 to a position with less weight distribution, balancing the weight and preventing the car from tilting and shaking during operation. The overall structure is simple and the operation is convenient and quick.

[0039] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
