[0015] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0016] As shown in Figure 1-3, a new type of household platform elevator structure includes an elevator shaft 1, the elevator shaft 1 has a double-opening hall door 2, and also includes a car 3 located in the elevator shaft 1, one side of the car 3 is open, and both ends of the open side of the car 3 are respectively provided with a detachable extension component, the extension component includes a fixed cavity 4 installed on the inner side wall of the opening of the car 3, one side of the fixed cavity 4 is open, and a sleeve component is provided inside the fixed cavity 4, the sleeve component is composed of a plurality of mutually nested cylinders 5, the sleeve component can be stored in the interior of the fixed cavity 4, and a folding telescopic connecting rod 6 is symmetrically provided inside the fixed cavity 4, the folding telescopic connecting rod 6 has an output end and two input ends, the output end of the folding telescopic connecting rod 6 is hinged with an abutment block 7, and the abutment Block 7 is fixedly connected to the smallest cylinder 5 in the sleeve assembly, a motor 8 is provided inside the fixed cavity 4, and a gear commutator 9 is provided at the output end of the motor 8. Two double-threaded screws 10 are symmetrically provided inside the fixed cavity 4, and the motor 8 drives the two double-threaded screws 10 to rotate through the gear commutator 9. The two input ends of the same folding telescopic connecting rod 6 are respectively threadedly connected to the same double-threaded screw 10. A card slot 14 is provided at one end of the two sleeve assemblies away from their respective fixed cavities 4, and an anti-pinch sensing device 11 is provided inside the card slot 14. A guide rail 12 is provided at the inner bottom of the car 3 and below the fixed cavity 4, and a slider 13 cooperating with the guide rail 12 is provided on the lower surface of the smallest cylinder 5 in the sleeve assembly.

[0017] The household platform elevator structure also includes components such as traction mechanism, counterweight mechanism, limit mechanism, safety mechanism, etc., which are all existing technologies. Since they are not the main improvement parts of this application, they are not listed one by one in this application, but this does not affect the sufficiency of the disclosure of this application. At the same time, the car 3 in the elevator structure of this application lacks a completely enclosed car door, so there is a certain risk. The highest floor for installation shall not exceed 3 floors. It is suitable for single-family villas and houses of a certain age that do not have elevators pre-installed, and can only be installed indoors.

[0018] like Figure 1 As shown, the hall door 2 is a double-leaf type, and a door frame is provided on the elevator shaft 1. The hall door 2 and the door frame are connected through an electromagnet. When the car 3 moves in the elevator shaft 1, the hall door 2 needs to be closed and magnetically fixed to the door frame. When the car 3 reaches the destination floor, the magnetic attraction between the hall door 2 and the door frame of the floor fails, making it easy to open the hall door 2. The hall door 2 is opened by pushing it outward, and a handle is provided on the outside of the hall door 2.

[0019] In this application, if Figure 2 and Figure 3As shown, there are three cylinders 5, and the adjacent cylinders 5 are slidably connected to each other. The cylinder 5 in contact with the fixed cavity 4 is also slidably connected to the fixed cavity 4. Flanges that engage with each other are provided between the cylinders 5 and between the cylinder 5 and the fixed cavity 4 to prevent the cylinders 5 from being disconnected when the extension component is fully extended. When the extension component is fully extended, the inner surfaces of the two cylinders 5 between the cylinder 5 farthest from the fixed cavity 4 and the fixed cavity 4 are also provided with flanges, so that when the extension component is contracted, all the cylinders 5 can be stored in the fixed cavity 4 in turn through the cooperation between the cylinder 5 farthest from the fixed cavity 4 and the flange inside the cylinder 5.

[0020] Both sides and the bottom side of the outer surface of the input end of the folding telescopic link 6 are in contact with the inner surface of the fixed cavity 4, so that the input end of the folding telescopic link 6 can move linearly along the double-threaded screw 10 in the fixed cavity 4. When the motor 8 controls the rotation of the double-threaded screw 10 through the gear commutator 9, it can drive the two input ends on the same folding telescopic link 6 to approach or move away from each other. When the two input ends on the same folding telescopic link 6 are close to each other, the folding telescopic link 6 is in an extended state, causing the extension component to extend. Through the two extension components in the car 3, the opening at the lower end of the car 3 is blocked, the car 3 is semi-closed, and the safety of the car 3 is improved.

[0021] When the slider 13 moves following the cylinder 5, it can improve the stability of the cylinder 5 after extension, and prevent the extension component, that is, the problem of poor stability after the multiple cylinders 5 are extended. At the same time, since the overall height of the extension component is not high, the height is set at 80cm-100cm, so only by setting the slider 13 under the cylinder 5, the stability of the extension component can also be effectively improved.

[0022] The anti-pinch sensing device 11 can prevent the extension component from pinching the user when extending. When the user is located between two extension components, the extension component cannot start to extend. Since the anti-pinch sensing device 11 is existing technology, it will not be described here in detail.

[0023] Furthermore, a slot 14 is provided on the lower surface of the fixed cavity 4, and the slider 13 can be moved to the inside of the slot 14 through the guide rail 12. The slot 14 can reduce the volume of the extension component exposed outside the fixed cavity 4 to increase the width of the entrance of the car 3 for user convenience.

[0024] Furthermore, after the slider 13 completely enters the interior of the guide rail 12, the sleeve assembly also completely enters the interior of the fixed cavity 4, further reducing the volume occupied by the extension assembly outside the fixed cavity 4, further increasing the width at the entrance of the car 3, and also improving the aesthetics of the device.

[0025] Furthermore, the fixed cavity 4 is fixed to the inner wall of the car 3 by bolts. When transporting heavier and wider objects, the fixed cavity 4 can be quickly removed from the inner wall of the car 3. After the transport is completed, the fixed cavity 4 can be re-fixed to the inner wall of the car 3.

[0026] Furthermore, a placement rack 15 is provided inside the fixed cavity 4, and a spring 16 is provided between the placement rack 15 and the smallest sleeve in the sleeve assembly. The spring 16 can improve the stability of the extension assembly after extension, and prevent the extension assembly from being fully extended. After the extension assembly is fully extended, friction noise is continuously generated between the various cylinders 5 due to loose connections.

[0027] The device can provide a low-height and foldable car door for the car 3, which can retain a relatively large car 3 space in a smaller elevator shaft 1 while providing appropriate safety protection measures for young children, thereby improving the safety and convenience of use for users of different age groups.

[0028] In the description of this utility model, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.
