[0024] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Please see Figures 1 to 3 This embodiment discloses an automatic elevator call device for elevator overload operation testing, including a call button module 100 and a call fixing module 200. The call button module 100 includes a housing 110, an electromagnet 120, a photosensitive sensor 130, and a pressing contact 140. The electromagnet 120 is mounted on the housing 110 and is provided with a push rod 121. The pressing contact 140 is fixed to the push rod 121, and the push rod 121 is connected to the iron core inside the electromagnet 120. The photosensitive sensor 130 is fixed to the inner wall of the housing 110 and is used to sense the elevator floor selection button indicator light. The call fixing module 200 is provided with a suction cup 210 and a bracket 220. The bracket 220 is composed of multiple bracket arms connected one by one. The first end of the bracket 220 is movably connected to the suction cup 210, and the second end of the bracket 220 is connected to the housing 110.

[0026] The electromagnet 120, through the magnetism generated by energization, pushes the push rod 121, thereby causing the pressing contact 140 to automatically press the elevator floor selection button 310, realizing the elevator call function. The photosensitive sensor 130 is used to detect the indicator light status of the elevator floor selection button 310, ensuring that the pressing contact 140 operates at the appropriate time. The elevator call fixing module 200, composed of the suction cup 210 and the bracket 220, is used to fix the entire device in a proper position inside the elevator, ensuring the stability and reliability of the device during overload testing. The pressing contact 140 is fixed to the push rod 121 of the electromagnet 120 by a threaded connection. The push rod 121 is fixed to the iron core inside the electromagnet 120. By energizing or de-energizing the electromagnet 120, the extension and retraction of the push rod 121 are controlled, causing the pressing contact 140 to briefly press the elevator floor selection button 310. After successful pressing, the indicator light of the button will light up. A photosensitive sensor 130 is fixed to the inner wall of the housing 110, with the photosensitive element facing downwards. It can determine whether the elevator floor selection button indicator light is on or off. When the target floor is reached, the indicator light on the floor selection button turns off, thus determining whether the target floor has been reached. A suction cup 210 and a bracket 220 are used to fix the entire device inside the elevator. The suction cup 210 and each bracket arm can be rotated and fixed via knobs, allowing the position between the suction cup 210 and the call button module 100 to be changed. In use, the suction cup 210 is attached near the elevator floor selection button 310 on the elevator control panel 300, and the call button module 100 is placed above the elevator floor selection button 310, thus enabling pressure control of the elevator floor selection button 310. In elevator overload operation tests, this device can automatically and accurately complete elevator call operations, improving test efficiency and reducing operational workload.

[0027] Please see Figure 3 The elevator call button module 100 also includes a magnet fixing block 150, through which the electromagnet 120 is mounted on the housing 110. The magnet fixing block 150 is used to fix the electromagnet 120, ensuring that it is stably mounted on the housing 110 of the elevator call button module 100.

[0028] Please see Figure 3 and Figure 7The call button module 100 is fixed to the elevator control panel 300 via the call fixing module 200. An electromagnet 120 controls the extension and retraction of the push rod 121, thereby driving the pressing contact 140 to press the elevator floor selection button 310 on the elevator control panel 300. The call fixing module 200 securely mounts the call button module 100 onto the elevator control panel 300. The electromagnet 120 generates a magnetic field through its internal coil, controlling the extension and retraction of the push rod 121. The extension and retraction of the push rod 121, via a connecting structure, drives the pressing contact 140 to press the elevator floor selection button 310 on the elevator control panel 300. When the electromagnet 120 is energized, it generates a magnetic force acting on the push rod 121, causing it to extend and retract along the guide structure, thereby moving the pressing contact 140 and pressing the elevator floor selection button 310, thus simulating manual operation to select the elevator floor.

[0029] Please see Figure 4 and Figure 7 The suction cup 210 is attached to the elevator control panel 300 to fix the call button module 100 to the elevator control panel 300. The function of the suction cup 210 is to firmly fix the call button module 100 through its adsorption properties, preventing the call button module 100 from shifting or falling off due to vibration during elevator operation.

[0030] Please see Figure 3 and Figure 4 A push rod 121 has a pressing contact 140 mounted on its first end and a spring 122 fitted on its second end. The pressing contact 140 is used to press the elevator floor selection button 310. The spring 122 provides a restoring force, allowing the push rod 121 to maintain a preset position when not pressed. When an external force is applied to the first end of the push rod 121 and the pressing contact 140 is pressed down, the push rod 121 moves inward against the restoring force of the spring 122. After the external force is released, the restoring force of the spring 122 returns the push rod 121 to its initial position, repeating the process. The elastic restoring force of the spring 122 ensures that the push rod 121 can stably and cyclically press and reset, thus enabling the pressing of the elevator floor selection button 310.

[0031] Please refer to Figure 3 and Figure 4The outer surface of the press contact 140 is covered with a soft material. The use of a soft material, such as soft rubber or sponge, on the outer surface of the press contact 140 can reduce the impact on the elevator floor selection button 310 during automatic elevator calls, protecting the surface of the elevator floor selection button 310. Furthermore, the position of the press contact 140 can be adjusted by screwing it into and out of the thread at the end of the push rod 121, adapting to different elevator brands and different height floor selection buttons. This ensures that the press contact 140 can accurately execute the elevator call operation when the electromagnet 120 is energized, improving compatibility with different elevator buttons.

[0032] Please see Figure 5 The outer casing 110 has a cuboid structure and is equipped with a side cover plate 111. The design of the side cover plate 111 makes the outer casing 110 easy to open and close, facilitating the installation and maintenance of internal components. When the call button module 100 needs maintenance or replacement of internal components, the internal structure can be quickly accessed by opening the side cover plate 111.

[0033] Please see Figure 6 The bracket 220 includes a first bracket arm 221, a second bracket arm 222, and a third bracket arm 223. The first end of the first bracket arm 221 is movably connected to the suction cup 210, the second end of the first bracket arm 221 is movably connected to the first end of the second bracket arm 222, and the first end of the third bracket arm 223 is movably connected to the second end of the second bracket arm 222. The housing 110 is mounted on the second end of the third bracket arm 223. The elevator call button module 100 is fixed to the third bracket arm 223. In use, the elevator call button module 100 is placed above the elevator floor selection button 310 to control the pressing of the elevator floor selection button 310.

[0034] Please see Figure 6 Both ends of the first support arm 221 and the second support arm 222 are provided with through holes 231, and fastening knobs 232 are inserted into the through holes 231. The third support arm 223 is provided with a mounting hole 233 on one side, and the third support arm 223 fixes the outer shell 110 through the mounting hole 233.

[0035] Please see Figure 7Two call button modules 100 are fixed to the elevator control panel 300 using suction cups 210 and brackets 220. These modules control the elevator selection buttons 310 at the bottom and top terminals, respectively. A photosensitive sensor 130 detects the lights on the bottom and top terminal selection buttons to determine if the selection signal has been registered by the elevator control system. The system ensures that each time the elevator reaches the bottom terminal and the button indicator light goes out, the call button module 100 automatically presses the top terminal selection button. Once the elevator reaches the registered top terminal, the button indicator light goes out, and the photosensitive sensor 130 detects this. Then, the call button module 100 automatically presses the bottom terminal selection button, illuminating its indicator light, and the elevator automatically moves to the bottom terminal. This cycle repeats continuously between the bottom and top terminals until 60 full-range tests are completed. During the elevator overload operation test, this device controls the elevator to run up and down 60 times continuously without interruption, replacing the manual operation process. By automatically pressing the elevator floor selection buttons, the automatic call function is achieved. It can automatically control the elevator to run multiple times without stopping within a continuous cycle, ensuring continuous operation between the bottom and top terminals, avoiding misoperation, improving test efficiency, and reducing the workload of operators.

[0036] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model 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 the present utility model.
