Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a household elevator with voice fault reminder. Background Art

[0002] An elevator is a vertical lift powered by an electric motor and equipped with a box-shaped cabin, used to transport people or goods in multi-story buildings. There are also step-type elevators, with treads mounted on tracks and running continuously, commonly known as escalators or moving walkways.

[0003] Current home elevators have certain safety hazards when in use. Due to the poor signal inside the elevator shaft, when people inside the elevator are trapped, they cannot send a distress signal to the outside in time, making it difficult to use the elevator safely. For this reason, we propose a home elevator with voice fault reminder to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to provide a home elevator with voice fault reminder to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a home elevator with voice fault reminder, comprising an elevator car and an alarm, an infrared ranging sensor fixedly installed at the center position of the bottom of the elevator car, a pyroelectric infrared sensor fixedly installed on one side of the inner wall of the elevator car, a main control box and a control panel respectively installed inside the elevator car, a timer installed inside the main control box, and shock-absorbing components symmetrically installed on the bottom of the elevator car.

[0006] Furthermore, the alarm is installed at the home end and is provided with a speaker.

[0007] Furthermore, the infrared ranging sensor is electrically connected to the main control box, and the alarm is electrically connected to the timer and the pyroelectric infrared sensor respectively.

[0008] Furthermore, the shock absorbing assembly includes a bottom block, which is fixedly connected to the bottom of the elevator car, and the outer side of the bottom block is slidably connected to a support shell, and the bottom of the inner wall of the support shell is fixedly connected to the groove at the bottom of the bottom block through a shock absorbing spring.

[0009] Furthermore, a guide slider is fixedly installed on the side wall of the support shell, and the guide slider is slidably connected to the groove on the outside of the bottom block. A damper is also installed between the support shell and the bottom block and on the inner side of the corresponding shock-absorbing spring.

[0010] Furthermore, a light panel is fixedly installed on the top of the inner wall of the elevator car, and a protective shell is fixedly connected to the side of the inner wall of the elevator car corresponding to the position of the pyroelectric infrared sensor.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] The utility model uses a pyroelectric infrared sensor to detect a signal of someone entering the elevator car. During the operation of the elevator, an infrared distance sensor is used to monitor whether the elevator is moving and its current position. When the elevator stops unexpectedly, the infrared distance sensor monitors the distance value unchanged. At this time, the timer starts timing, and after a few minutes, the elevator floor signal is transmitted to the alarm at the home end, and an alarm is sounded to remind that there is someone in the elevator car, so that rescue can be provided in time. The home elevator with voice reminder fault has a reasonable structural design and is easy to use. When a home elevator breaks down, it can automatically detect whether there are trapped people inside through human body sensing, and automatically transmit the situation to the home end for a period of time to remind, so that quick rescue can be obtained, realizing the year-round 24-hour normalized and safe use of the home elevator.
