In the use of elevators, smooth operation is very important. As time goes by, people age, especially the elderly, sick and disabled, and their lives are extremely inconvenient. However, because there was no space planned for the installation of elevators in the building at that time, the elevator could only be planned using the existing space.
[0003] The patent specification with the announcement number CN208135690U discloses an elevator car, which includes a car body, including a ceiling, a car floor and a car wall; the car floor is provided with an emergency escape hatch; a pair of vertical beams are respectively arranged on the outside of the car walls on both sides; an upper beam is fixed on the upper side of the ceiling and connected to the top of a pair of vertical beams; a lower beam is fixed on the lower side of the car floor and connected to the bottom of a pair of vertical beams; a buffer emergency cabin is fixed on the lower part of the car floor; the buffer emergency cabin includes a bottom plate and a rectangular columnar cabin body that can be retracted up and down. It is convenient for personnel to escape by arranging a buffer emergency cabin on the car floor, reducing the extra space required for the elevator car to enter the bottom of the elevator shaft, and at the same time, the retracted cabin body cooperates with the shock-absorbing spring to form the last additional buffer device after the elevator suddenly falls, thereby improving the overall safety performance of the elevator car.
[0004] However, in the implementation of relevant technologies, it was found that the elevator car of the above design has the following problems: in the above technical solution, a buffer emergency cabin is set on the car floor to facilitate people in the car to pass through the emergency escape hatch, enter the buffer emergency cabin and exit through the elevator door on the lower floor.

In this way, the elevator requires a deeper pit, which cannot be designed and installed by conventional elevators, and the operability is low. In view of this, a shallow pit 90-degree through-door elevator car balance structure is provided to overcome the above defects. Utility Model Content
