[0025] The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0026] This utility model relates to a pressure detection threshold structure, including a support plate 1, a support column 2, and a pressure sensor 4. The support plate 1 serves as a stepping element, and the support column 2 is supported below the support plate 1 and detachably connected to the support plate 1, including at least two columns connected to both ends. Depending on the requirements, one or more support columns 2 can also be set in the middle. The pressure sensor 4 is set between the support column 2 and the support plate 1 to detect the pressure change between the support plate 1 and the support column 2 in real time, thereby determining whether someone has passed by. The pressure sensor 4 may include one or more, and the pressure sensor 4 is equipped with or connected to a signal transmitting device, which can transmit the received pressure signal to the control system to control the opening and closing of the subway door.

[0027] The support plate 1 and the support column 2 are connected by bolts 3. The pressure sensor 4 can be set at the connection of bolts 3. When the support plate 1 is subjected to force, the pressure will be reflected at the connection of bolts 3. By setting the pressure sensor 4 at the connection of bolts 3, the pressure on the support plate 1 can be sensed in real time.

[0028] In some embodiments of this invention, pressure sensors 4 are respectively arranged below a set of diagonally opposite corners of the support plate 1, or below the four corners, symmetrically or evenly, resulting in a more reasonable pressure sensing range. In some embodiments of this invention, the pressure sensors 4 can be strip sensors, with one strip pressure sensor 4 installed on each column and pressure sensors 4 installed at the joints of multiple bolts 3, enabling sensitive sensing of the pressure exerted on the support plate 1 by people passing through various points on the threshold.

[0029] In some embodiments of this invention, the pressure sensor 4 is U-shaped. The support plate 1 and the support column 2 are connected by bolts 3, and the U-shaped pressure sensor 4 surrounds the threaded rod of the bolt 3. The pressure sensor 4 is incorporated into the bolt 3 structure as a gasket, fitting the bolt 3 more closely and sensing the pressure on the bolt 3. Installation is also more convenient; the pressure sensor 4 can be inserted by loosening the bolt 3, making replacement and maintenance easier. This is especially suitable for the renovation of old subway systems, requiring no major alterations to the equipment structure, only modifications to the bolt 3. The pressure sensor 4 can be installed at one bolt 3, or symmetrically at one or more pairs of bolts 3. Different installation or modification schemes can be selected according to the threshold usage environment, usage habits, or site characteristics.

[0030] In some embodiments of this invention, the support column 2 includes side columns and a central column 21. The side columns connect to and support both ends of the support plate 1, providing support and causing the support plate 1 to arch for stepping. The central column 21 is U-shaped, with a pressure sensor 4 at its bottom center. A trigger column 22 is located below the support plate 1, corresponding to the position of the pressure sensor 4. The U-shaped central column 21 is deformable, with both ends contacting the bottom surface of the support plate 1. When the support plate 1 is stepped on and deforms, it compresses the central column 21, causing it to deform as well. The trigger column 22 then lowers and touches the pressure sensor 4. This new structure, integrating the central column 21, pressure sensor 4, and trigger column 22, can be installed in existing threshold structures, suitable for both new subway thresholds and retrofitting existing equipment.

[0031] The present invention will be further described below through specific embodiments.

[0032] Example 1: A pressure detection threshold structure includes a support plate 1, a support column 2 and a pressure sensor 4. The support column 2 includes two columns, left and right, which are respectively connected to the support plate 1 by bolts 3. The pressure sensor 4 is provided between the support column 2 and the support plate 1, and is respectively set at the 14 corners of the support plate 1.

[0033] Example 2: A pressure detection threshold structure includes a support plate 1, a support column 2 and a pressure sensor 4. The support column 2 includes three columns, left, middle and right, which are connected to the support plate 1 by bolts 3 respectively. Each support column 2 has a strip-shaped pressure sensor 4 in the middle, and each pressure sensor 4 has a bolt 3 connection at both ends.

[0034] Example 3: A pressure detection threshold structure includes a support plate 1, support columns 2 and pressure sensors 4. The support columns include four columns arranged in sequence. Each support column 2 is connected to the support plate 1 by two bolts 3. A U-shaped pressure sensor 4 is provided on one bolt 3 of each support column, which is wrapped around the bolt 3 in the form of a washer. The pressure sensors 4 on two adjacent support columns 2 are installed on bolts 3 on different sides.

[0035] Example 4: A pressure detection threshold structure includes a support plate 1, a support column 2, and a pressure sensor 4. The support column includes a side column and a central column 21. The side column includes two columns, left and right, which are respectively connected to the two ends of the support plate 1. The central column 21 is U-shaped and has a pressure sensor 4 at its bottom. A trigger column 22 is connected below the support plate 1. The trigger column 22 corresponds to the position of the pressure sensor 4. When the support plate 1 is compressed and deformed, the trigger column 22 can trigger the pressure sensor 4.

All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
