Description

Technical Field

[0001] The utility model relates to the technical field of elevator cars, in particular to an elevator car with a structure of stopping when encountering a car. Background Art

[0002] High-rise residential buildings are generally equipped with elevators. For their own convenience and to facilitate charging of electric vehicles, some residents take electric vehicles to upper floors via elevators for easy charging indoors or place the electric vehicles in the corridor. However, charging electric vehicles indoors can cause fire risks, and placing electric vehicles in the corridor affects the use of fire escapes. Therefore, some electric vehicle identification and prevention mechanisms are usually installed in elevators to prevent residents from transporting electric vehicles upstairs.

[0003] For example, the elevator car electric vehicle identification and blocking mechanism with application number 202223540079.6 detects passengers entering the annular frame through the monitoring component when in use. If a battery car is identified, the blocking mechanism is driven. The blocking mechanism forms a plurality of protrusions and grooves distributed front and back on the inner bottom wall of the annular frame. In this way, when the passenger pushes the battery car into the elevator car, the battery car wheel will be blocked by the protrusion. At the same time, it is easy to fall into the groove and jam the wheel, making it impossible for the passenger to push the battery car in, while other passengers can directly step over the blocking mechanism to enter the elevator car and take the elevator. While blocking the battery car, it does not affect other passengers getting on and off the elevator, which is more practical. However, the device needs electric components to drive it, has a high failure rate, and is inconvenient to disassemble and assemble.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a car elevator with a structure that stops when encountering a car is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 5As shown, a car elevator with a car-stopping structure comprises a car 1 and a mounting plate 2 mounted on the inner bottom of the car 1, two shafts 3 are fixedly connected to the upper surface of the mounting plate 2, the upper and lower ends of the outer circumferential surface of the shaft 3 are provided with a first elastic shaft 4, the outer circumferential surface of the first elastic shaft 4 is fixedly connected with an inner gate plate 5, the middle outer circumferential surface of the shaft 3 is provided with a second elastic shaft 6, the outer circumferential surface of the second elastic shaft 6 is fixedly connected with an outer gate plate 7, a car-blocking mechanism 8 is arranged inside the car 1, the mounting plate 2 is fixedly connected to the inner bottom of the car 1 by screws, and a glue hole is provided on the screw hole. The front surface of the car 1 is provided with a car door, and an infrared sensor is arranged inside the car door. When an object is detected to be blocked, the car door is in an open state, and the elevator stops running. The first elastic shaft 4 and the second elastic shaft 6 are provided with springs inside to ensure that the gate is reset. The car blocking mechanism 8 includes a trigger groove 81 opened at the bottom of the car 1, and a concave block 82 is slidably connected inside the trigger groove 81. Extension rods 83 are fixedly connected at both ends of the concave block 82. A locking mechanism 84 is arranged above the extension rod 83 and inside the shaft rod 3. The upper surface of the concave block 82 is concave. The outer cylindrical surface of the tire is fitted to the greatest extent. The locking mechanism 84 includes a wire drawing 841 fixedly connected to the upper surface of one end of the extension rod 83. The upper end of the wire drawing 841 is fixedly connected to a clamping block 842. The upper end of the clamping block 842 is fixedly connected to a reset spring 843. The upper surface of the upper first elastic shaft 4 is fixedly connected to a toothed disc 844. After the reset spring 843 is reset, the clamping block 842 rises, and the inner gate plate 5 can resume the rotation effect. The inner surface of the shaft 3 is provided with a limiting groove 31. The outer surfaces of both sides of the clamping block 842 are fixedly connected to the limiting blocks 8421. When the door of the car 1 is opened, the clamping block 842 is locked. When the elevator is turned on, an electric vehicle or a bicycle enters the car 1. When the vehicle body pushes open the inner gate plate 5, the front wheel of the vehicle must first pass through the trigger groove 81 and press the concave block 82 inside the trigger groove 81. The concave block 82 pulls the wire 841 through the extension rod 83, and the block 842 is inserted into the teeth of the gear plate 844. The limit block 8421 slides inside the limit groove 31 to prevent the first elastic shaft 4 from rotating. At this time, the inner gate plate 5 will not rotate compliantly due to the continued push of the vehicle, and the middle and rear part of the vehicle will also find it difficult to enter the interior of the car 1, resulting in the inability to close the car door and the elevator stopping operation.

[0024] like Figure 3 and Figure 6 As shown, a through hole 9 is opened on the inner top of the car 1, a ventilation fan 10 is fixedly connected inside the through hole 9, and a filter cover is fixedly connected to the upper surface of the car 1 to prevent dust accumulation from affecting the heat dissipation effect.

[0025] Furthermore, a mesh cover 11 is installed at the lower eaves of the through hole 9 , and a filter screen 12 is arranged on the upper surface of the mesh cover 11 . The mesh aperture of the mesh cover 11 is larger than the filter aperture of the filter screen 12 .

[0026] Working principle: when using the elevator with the car-stop structure, first, when the door of the car 1 is opened, an electric car or bicycle enters the car 1, and in the process of the car body pushing open the inner gate plate 5, the front wheel of the vehicle must first pass through the trigger groove 81 and press the concave block 82 inside the trigger groove 81. The concave block 82 pulls the wire 841 through the extension rod 83, and the block 842 is inserted into the teeth of the toothed disc 844. The limit block 8421 slides inside the limit groove 31 to prevent the first elastic shaft 4 from rotating. At this time, the inner gate plate 5 will not rotate obediently due to the continued push of the vehicle, and the middle and rear part of the vehicle will also find it difficult to enter the interior of the car 1, resulting in the door being unable to be closed, the elevator stopping operation, and the ventilation fan 10 exhausts the air in the elevator to the outside. At the same time, the air is also exchanged inside and outside in the through hole 9. The filter screen 12 can be cleaned regularly by opening the mesh cover 11. This is the working principle of the elevator with the car-stop structure.
