[0035] In order to make the utility model's purpose, technical scheme and advantage more clearly, following combining with the drawing and example, this utility model carries out further detailed explanation.

[0036] In one embodiment, as Figures 1-6As shown, an elevator remote control alarm device includes a base 1, a bracket 2 fixedly installed on the top of the base 1, a first driver 3 fixedly installed on the top of the bracket 2, a second driver 5 fixedly installed on the top of the bracket 2, and a car 4 connected to the two sets of drivers. The car 4 consists of a body 41, a handrail 42, and a controller 43. The inner wall of the body 41 is fixedly connected to both ends of the handrail 42, and one side of the inner wall of the body 41 is fixedly connected to the controller 43. A sliding groove is provided on the side of the car 4, and the sliding groove matches the bracket 2.

[0037] In this embodiment, a bracket 2 is installed on the base 1. When the car 4 is driven by the first driver 3, sliding grooves are opened on both sides of the car 4, so that the car 4 slides up and down on the bracket 2. At the same time, the car 4 is prevented from swaying left and right, which would cause an unpleasant experience for the people inside the car 4. At the same time, two sets of drivers are driven at the same time to prevent the car 4 from floating in the air if a single driver fails or does not work, which would make it difficult to ensure the safety of the people inside the car 4. By setting two sets of drive sources, the auxiliary drive source can help the car 4 land smoothly when the main drive source does not work.

[0038] In one embodiment, as shown in the figure, the deceleration assembly 6 installed on the side of the car 4 includes:

[0039] The pneumatic brake consists of a retainer 61, an airbag 62 bolted to the retainer 61, a push plate 63 driven by the airbag 62, a pressing block 64 linked to the push plate 63, and a carrier 65 fixed to the retainer 61; a pressure sensor is integrated into the carrier 65; a shock-absorbing assembly 8 is provided on the top of the base 1, including a base frame 81, a hydraulic rod 82, a resetter 83, and a top plate 84 that supports them; a sliding groove is provided on the side of the car 4, and the sliding groove matches the bracket 2; multiple sets of sensors are installed in rows from top to bottom on the bracket 2, and the pneumatic brake is electrically connected to the sensors; the multiple sets of sensors sense the elevator's movement on the bracket 2. The distance moved per second is used to determine whether the elevator is experiencing an overspeed or slow descent. In either case, a signal is transmitted to the inflation component, which is an electric air pump. The signal is transmitted to the electric air pump, which then starts working, causing the airbag 62 to inflate rapidly. The inflation compresses the push plate 63, which slides towards the opening of the fixture 61. At the same time, the push plate 63 compresses the pressing block 64, causing the pressing block 64 to press against the cable on the carrier 65, thereby reducing the speed of the cable and slowing down the elevator. This increases the survival probability of people on the elevator during a fall and also increases the effective rescue time for rescuers.

[0040] In one embodiment, as shown in the figure, the shock absorption assembly 8 includes a base frame 81, a hydraulic rod 82 fixedly installed on the top of the base frame 81, and a resetter 83 fixedly installed on the top of the base frame 81. The top of the hydraulic rod 82 and the resetter 83 are connected to a top plate 84. The speed of the elevator fall is reduced by the deceleration assembly 6. In conjunction with the shock absorption assembly 8, the hydraulic rod 82 provides a buffering effect on the falling elevator. At the same time, the top plate 84 is made of rubber, which provides an elastic buffering effect when it touches the car 4 falling to the bottom. When the elevator rises, the resetter 83 drives the top plate 84 to reset, so as to withstand multiple buffering impacts, reduce the injury caused to the people inside the elevator by the elevator fall, and increase the survival probability of trapped people.

[0041] In one embodiment, as shown in the figure, the elevator car 4 consists of a body 41, handrails 42, and a controller 43. The inner wall of the body 41 is fixedly connected to both ends of the handrails 42, and one side of the inner wall of the body 41 is fixedly connected to the controller 43. The controller 43 has: a housing 431, a control area 432 with a two-stage push-button switch on the front; a display area 433 and a power supply compartment 434 on the side; a rotatable and expandable rotating rod 435 forming an angle limiting structure with the body 41; the handrails 42 are wrapped with soft material; magnetic charging contacts are provided inside the housing 431; and the controller 43 is a detachable magnetic structure. This is prior art and will not be described in detail here. In the event of a power outage in the elevator, a backup power supply 434 is still provided inside the housing 431 to prevent the elevator from being unable to alarm after a power outage, thus affecting the rescue time for trapped personnel.

[0042] In one embodiment, as shown in the figure, the control area 432 includes an alarm button, a call button, and a lighting button. The alarm button requires a three-second press to trigger, and the remote control terminal provides vibration feedback after triggering. Multiple sets of buttons are used to achieve different functions, and a three-second delay prevents accidental activation. Through pressure sensing (≥3N) + dynamic delay (adjustable from 2-5 seconds) dual verification, the false alarm rate is reduced from 5.8% in traditional designs to 0.3%. An environmental adaptive function is also included; for example, if continuous severe vibration is detected, the trigger time is automatically shortened. The database also records multiple application scenarios.

[0043] For example, in a medical emergency scenario: after a heart patient triggers an alarm: the location is automatically sent to the 120 emergency medical system, the elevator door is opened in advance, and the stretcher passage is released;

[0044] In a security scenario, during a robbery: a concealed alarm simultaneously transmits the physical characteristics of the perpetrator to the police, and the elevator automatically stops at a floor with surveillance cameras;

[0045] Age-friendly modifications: Fall detection function: Automatically triggered by an accelerometer (±8g), with voice system guiding emergency procedures.

[0046] The above embodiment discloses an elevator remote control alarm device, wherein, by setting a deceleration component 6, a deceleration function is applied when the car 4 descends at excessive speed, reducing the falling speed of the car 4. At the same time, in conjunction with the shock absorption component 8, the elevator is prevented from hitting the ground directly, reducing the probability of people being injured. Meanwhile, by setting a controller 43, people can easily set up alarms to deal with different scenarios.

[0047] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
