[0014] Beneficial effects: Compared with the prior art, the present invention provides a movable stopping device for an elevator car, which has the following beneficial effects:

[0015] 1. For the movable stopping device for an elevator car, through the arranged stopping buffer mechanism, when the elevator needs to perform a stopping operation, the rotation of the rotating movable rod can be driven by controlling the motor. The inner wall of the stopping telescopic frame engages with the outer wall of the rotating movable rod through threads. After the rotating movable rod is driven to rotate by controlling the motor, the telescoping of the stopping telescopic frame can be controlled. When stopping is not required daily, the stopping telescopic frame is located at both ends of the stopping control frame. When a stopping operation is required, the stopping telescopic frame can be extended outwards, and the stopping block can be controlled to be inserted into the buffer moving groove. The lower end of the stopping block contacts the buffer plate. A buffer damper and a buffer elastic member are arranged at the lower end of the buffer plate. When the stopping block contacts the buffer plate, the buffer damper and the buffer elastic member in the buffer moving groove can effectively absorb the impact energy, reduce the vibration and impact force when the elevator stops, protect passengers and equipment from damage, and the stopping telescopic frame can be flexibly telescoped as needed to adapt to the stopping requirements at different heights and positions, and is applicable to various types of elevators and building environments. By adopting the combination of the buffer damper and the buffer elastic member, various emergencies can be effectively coped with, the reliability and durability of the stopping device are improved, and the shock absorption effect is also improved. A good shock absorption effect can reduce the discomfort when the elevator stops and enhance the riding experience of passengers.

[0016] 2. For the movable stopping device for an elevator car, the arranged protective, reinforcing and heat dissipation mechanism can protect and reinforce the stopping control frame, and can also perform heat dissipation operation when the control motor is working. The reinforcing protective cover is positioned at the upper end of the elevator through the positioning connecting strip and bolts, which enhances the firmness. And the reinforcing protective cover covers the outside of the stopping control frame to play a protective role for the stopping control frame. The stopping telescopic frame can move through the inside of the through hole. Then the heat dissipation control frame is also positioned inside the positioning heat dissipation hole through bolts, which is convenient for disassembly and maintenance. The dust-proof net is positioned with the threaded hole through bolts, which is convenient for disassembly. The heat dissipation fan is located at the upper end of the bracket and is driven by a micro motor to dissipate heat for the control motor. By protecting and reinforcing the outside of the stopping control frame through the reinforcing protective cover, damage to the stopping device caused by external objects or personnel can be prevented, ensuring normal operation in case of emergency and improving the safety of the entire elevator system. By dissipating heat for the control motor through the heat dissipation fan, the working temperature of the control motor can be effectively reduced, reducing the aging and damage of the control motor caused by high temperature and extending the service life of the control motor. The heat dissipation and protection measures can reduce the occurrence probability of control motor failures. The external protection and reinforcement measures can make the stopping device better adapt to various harsh working environments, such as high temperature, humidity, dust, etc., and enhance the adaptability and versatility of the stopping buffer mechanism.

[0034] Working principle: This elevator car movable stopping device includes an elevator 1, a protective reinforcement and heat dissipation mechanism 2, and a stopping and buffering mechanism 3. When the elevator 1 needs to perform a stopping operation, the rotation of the rotating movable rod 311 can be driven by controlling the motor 310. The inner wall of the stopping telescopic frame 312 engages with the outer wall of the rotating movable rod 311 through threads. After the motor 310 drives the rotation of the rotating movable rod 311, the telescoping of the stopping telescopic frame 312 can be controlled. When stopping is not required daily, the stopping telescopic frame 312 is located at both ends of the stopping control frame 308. When a stopping operation is needed, the stopping telescopic frame 312 can be extended outwards, and the stopping block 314 is controlled to insert into the buffer moving slot 304. The lower end of the stopping block 314 contacts the buffer plate 305. The buffer damper 306 and the buffer elastic member 307 are arranged at the lower end of the buffer plate 305. When the stopping block 314 contacts the buffer plate 305, the buffer damper 306 and the buffer elastic member 307 in the buffer moving slot 304 can effectively absorb the impact energy, reduce the vibration and impact force when the elevator 1 stops, protect passengers and equipment from damage, and the stopping telescopic frame 312 can be telescopically adjusted flexibly according to needs to adapt to the stopping requirements at different heights and positions, applicable to various types of elevators and building environments. The combination of the buffer damper 306 and the buffer elastic member 307 can effectively cope with various emergencies, improve the reliability and durability of the stopping device, and also improve the shock absorption effect. A good shock absorption effect can reduce the discomfort when the elevator 1 stops and enhance the riding experience of passengers. Through the provided protective reinforcement and heat dissipation mechanism 2, the stopping control frame 308 can be protected and reinforced, and heat dissipation operation can also be performed on the motor 310 when it is working. The reinforcement protective cover 201 is positioned at the upper end of the elevator 1 through the positioning connection bar 202 and bolts, enhancing the firmness, and the reinforcement protective cover 201 covers the outside of the stopping control frame 308 to play a protective role for the stopping control frame 308. The stopping telescopic frame 312 can move through the inside of the through-hole 203. Then, the heat dissipation control frame 205 is also positioned inside the positioning heat dissipation hole 204 through bolts, which is convenient for disassembly and maintenance. The dust-proof net 209 is positioned with the threaded hole 206 through bolts, which is convenient for disassembly. The heat dissipation fan 208 is located at the upper end of the bracket 207 and is driven by a micro-motor to dissipate heat from the motor 310. By protecting and reinforcing the outside of the stopping control frame 308 with the reinforcement protective cover 201, damage to the stopping device caused by external objects or personnel can be prevented, ensuring normal operation in case of emergency and improving the safety of the entire elevator system. By dissipating heat from the motor 310 with the heat dissipation fan 208, the working temperature of the motor 310 can be effectively reduced, reducing the aging and damage of the motor 310 caused by high temperature and extending the service life of the motor 310. The heat dissipation and protection measures can reduce the occurrence probability of motor 310 failures. The external protection and reinforcement measures can enable the stopping device to better adapt to various harsh working environments, such as high temperature, humidity, dust, etc.,The adaptability and versatility of the stopping buffer mechanism 3 are enhanced.
