Detailed Description

The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the invention easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the invention.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When a component is referred to as being "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

As shown in fig. 1 and 2, the deformable elevator car of the invention comprises a movable plate assembly 1, a top wall 2 and adjacent first and

second side walls

3 and 4, wherein the edges of the first and

second side walls

3 and 4 are provided with a guard plate 5 extending upwards, a step 6 is formed between the first and

second side walls

3 and 4 and the guard plate 5, and a notch 21 is formed at one side of the top wall 2 close to the first side wall 3. The movable plate assembly 1 includes a first movable plate 11, a second movable plate 12 and a third movable plate 13 connected in sequence and rotatably connected to each other, in this embodiment, the first movable plate 11, the second movable plate 12 and the third movable plate 13 are connected by a hinge 10. The end of the first flap 11 remote from the second flap 12 is rotatably connected to the first sidewall 3, and the end of the third flap 13 remote from the second flap 12 is rotatably connected to the edge of the gap 21 of the top wall 2, complementing the gap 21. The movable panel assembly 1 includes a first state in which the space of the car is increased by arching upward and a second state in which the space of the car is decreased by denting downward.

As shown in fig. 3, in the first state, the first movable plate 11 is attached to the first side wall 3, and the second movable plate 12 and the third movable plate 13 are flush with the top wall 2, so that the internal space of the elevator in normal operation is ensured, and the passenger riding requirement is met. The second movable plate 12 or the third movable plate 13 is provided with a pin seat 7 and a bolt 8 slidably connected with the pin seat 7, and in the embodiment, the pin seat 7 and the bolt 8 are provided on the second movable plate 12, so that the stress is more balanced. As shown in fig. 5, the latch 8 is inserted above the step 6 to fix the second flap 12 and the third flap 13 in a horizontal position, thereby increasing the space of the car. An electric switch 9 is arranged on the guard plate 5, and when the guard plate is in the first state, the bolt 8 is connected with a contact of the electric switch 9, so that the elevator safety loop is in a connected state, and the normal work of the elevator safety loop is ensured.

As shown in fig. 4, in the second state, the first flap 11 is located in a horizontal position, and the second flap 12 and the third flap 13 are located in a vertical position. When the elevator needs to enter the top of the elevator car for maintenance, a maintainer enters the car top and then moves the bolt 8 back, the first movable plate 11, the second movable plate 12 and the third movable plate 13 deform towards the inside of the car top, the danger avoiding space of the car top is increased, the electrical switch 9 resets and enters a non-working state, the safety loop is disconnected, and the elevator can only be overhauled and operated to ensure the safety of the maintainer. The guard plate and the second side wall play a role in isolating and protecting the maintainers and the well part, and the friction risk is avoided.

The deformable elevator car has wide application range, and the elevator with a box body structure can use the scheme; the reliability is high, and the safety of car roof maintainers is ensured through the double detection standards of the mechanical bolt and the electrical switch; the structural design of other parts of the elevator is not influenced, and according to the maintenance rule of the elevator, passengers are not allowed in the car when the elevator is overhauled, so that the layout of other parts of the elevator is not influenced after the elevator is deformed into the car, and the elevator is more reasonable in design.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
