Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to an energy-saving home elevator. Background Technology

[0002] With economic development, the elevator industry is gradually moving towards energy conservation. However, current elevators cannot achieve effective energy saving. When the weight of the elevator car is less than the weight of the counterweight, the traction motor generates electricity. However, current elevators cannot make reasonable use of this electricity, resulting in energy waste. Therefore, it is crucial to realize an energy-saving elevator.

[0003] To achieve energy conservation in elevators, Chinese patent CN109573793B describes an energy-saving elevator that generates electricity by driving a generator during elevator as it ascends and descends, supplying power to the elevator's lighting and ventilation systems. This allows for efficient use of electrical energy. While this patent improves energy utilization and achieves energy conservation, certain technical problems remain. When the elevator ascends, the positions of passengers inside are not fixed, resulting in uneven weight distribution at the bottom of the elevator car. Consequently, the force on the car is uneven when the traction motor drives it upwards. Since the traction motor is fixedly connected to the center of the upper part of the car via cables, this significantly increases the load on the traction motor, leading to greater energy consumption and hindering the effective energy conservation of the elevator.

[0004] Therefore, in order to adjust the cable appropriately according to the position of the people standing inside the chassis, and to ensure that the chassis is evenly stressed when the traction motor drives it to rise, thus preventing excessive energy consumption of the traction motor due to uneven stress on the chassis and the inability to achieve energy saving, a skill-based home elevator is proposed to solve the technical problems existing in the above-mentioned prior art. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an energy-saving home elevator, which solves the problem that existing elevators cannot adjust the cable appropriately according to the position of the people inside the elevator car, resulting in uneven force on the car car during lifting, causing excessive energy consumption of the traction motor and failing to achieve energy saving.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving home elevator, comprising a frame structure installed in an elevator shaft, a counterweight on one side of the frame structure, a movably mounted housing frame inside the frame structure, and auxiliary moving structures on the upper and lower surfaces of the housing frame. A drive structure for lifting and lowering the elevator is also provided on the frame structure. An elevator weighing sensor is located at the bottom of the inner side of the housing frame. A housing is located inside the housing frame, and the lower end of the housing is connected to the elevator weighing sensor. The elevator weighing sensors are symmetrically distributed. Adjustable moving structures, adjustable according to the elevator weighing sensor values, are symmetrically distributed on the upper end of the housing frame. The moving structure includes a movable base, a motor, a threaded shaft, and a movable plate. The movable base is symmetrically mounted on the upper end of the chassis frame, and a motor is located at the outer end of the movable base. A threaded shaft is connected to the output end of the motor, and a movable plate is located on the surface of the threaded shaft. A sliding shaft is also symmetrically located on the movable base, and the sliding shaft passes through the movable plate. A hook is located at the upper end of the movable plate, and the hook is connected to the drive structure via a cable. The cable is connected to the counterweight via the drive structure. When the drive structure moves the chassis frame up and down, if the weight of the chassis frame is less than the counterweight, the drive structure is in a power generation state and generates electrical energy. A battery is located at the upper end of the chassis frame, and the battery is connected to the drive structure. The motor is connected to the battery.

[0007] Further, the frame structure includes a first mounting bracket, a first chassis guide rail, a second mounting bracket, a second chassis guide rail, and a stabilizing plate; wherein the two sets of first mounting brackets and the two sets of first chassis guide rails are all securely connected by the stabilizing plate and are installed on the elevator shaft by the stabilizing plate. The stabilizing plate on the second mounting bracket has a second chassis guide rail on its inner side, and the stabilizing plate on the first mounting bracket has a first chassis guide rail on its inner side. An auxiliary moving structure is movably provided on the surface of the first chassis guide rail.

[0008] Furthermore, the auxiliary moving structure includes a mounting body, a movable plate, a pin shaft, a telescopic spring, and a movable wheel; the auxiliary moving structure is respectively installed on the upper end face and the lower end face of the chassis frame, and is installed on the upper and lower surfaces of the chassis frame. The mounting body is provided on the outer surface of the chassis frame, the pin shaft is provided on the mounting body, the movable plate is provided on the surface of the mounting body, the movable wheel is provided at the end of the movable plate, the pin shaft passes through the movable plate, and the telescopic spring is provided on the surface of the pin shaft, with one end of the telescopic spring contacting the surface of the movable plate.

[0009] As a preferred technical solution, the drive structure includes a side frame, a fixed plate, and a traction motor. The side frame is mounted on the surface of the first mounting frame and the surface of the second mounting frame. A fixed plate is connected between the two sets of side frames. The upper end of the fixed plate is provided with a traction motor and a cable sheave. The traction motor is connected to a battery, and its cable is connected to the counterweight through the cable sheave.

[0010] Furthermore, the chassis frame is divided into four areas: A, B, C, and D. The elevator weighing sensors are located at the center of each area, and the adjustable moving structure is installed on the four areas A, B, C, and D located on the upper surface of the chassis frame.

[0011] As a preferred technical solution, one end of the cable is divided into four groups of cables, and these cables are connected to each group of movable plates.

[0012] Compared with the prior art, this utility model provides an energy-saving home elevator with the following advantages:

[0013] 1. After personnel enter the elevator chassis, the elevator's weighing sensors weigh each area. Then, an auxiliary moving structure initially moves the moving plate towards the center of the upper part of the chassis frame. If the weight of a certain area is uneven, the auxiliary moving structure moves the moving plate closer to the center of that area. This, through cable pulling, effectively maintains a uniform weight distribution across the chassis frame during lifting, reducing the energy loss during traction motor startup caused by uneven weight distribution. Furthermore, the energy loss from the auxiliary moving structure and interior lighting is mitigated by the traction motor generating electricity when the overall weight of the chassis frame is less than the counterweight. This electricity is stored in batteries for use, eliminating the need for separate lead wires and effectively achieving energy savings. Therefore, this solution addresses the problem in existing elevators where the inability to adjust the cable according to the personnel's position during lifting leads to uneven force distribution, resulting in excessive energy consumption of the traction motor and hindering energy conservation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0024] Please see Figure 1-8This utility model provides the following technical solution: an energy-saving home elevator, including a frame structure installed in an elevator shaft, a counterweight 12 on one side of the frame structure, a housing frame 5 movably installed inside the frame structure, and auxiliary moving structures on the upper and lower surfaces of the housing frame 5. A drive structure for lifting and lowering the elevator is also provided on the frame structure. The feature is that: an elevator weighing sensor is provided at the bottom of the inner side of the housing frame 5; a housing 6 is provided inside the housing frame 5, and the lower end of the housing 6 is connected to the elevator weighing sensor. The elevator weighing sensors are symmetrically distributed. An adjustable moving structure, adjustable according to the elevator weighing sensor, is symmetrically distributed on the upper end of the housing frame 5. The adjustable moving structure includes a moving base 7, a motor 8, a threaded shaft 9, and a moving plate. 10; Its movable base 7 is symmetrically installed on the upper end of the chassis frame 5, and a motor 8 is provided at the outer end of the movable base 7. A threaded shaft 9 is connected to the output end of the motor 8. A movable plate 10 is provided on the surface of the threaded shaft 9. A sliding shaft 23 is also symmetrically provided on the movable base 7. This can ensure the stability of the movable plate 10 when the cable is tightened. The sliding shaft 23 passes through the movable plate 10. A hook is provided at the upper end of the movable plate 10. The hook is connected to the drive structure through the cable. The cable is connected to the counterweight 12 through the drive structure. When the drive structure drives the chassis frame 5 to rise and fall, if the weight of the chassis frame 5 is less than the counterweight 12, the drive structure is in the power generation state to generate electrical energy. A battery is provided at the upper end of the chassis frame 5. The battery is connected to the drive structure, and the motor 8 is connected to the battery.

[0025] In this implementation plan, the specific working principle is as follows: In this home elevator, the unmanned chassis frame 5 is first moved upward or downward by the drive structure, causing the drive structure to generate electrical energy, which is stored in the battery. After storage, personnel enter the chassis 6. At this time, the elevator weighing sensor detects the weight of each area, and the motor 8 drives the threaded shaft 9 to rotate, which in turn drives the moving plate 10 to move, which in turn drives the cable to move towards the center of each area. This allows for appropriate adjustment of the cable according to the area where the personnel are standing in the chassis 6, thereby achieving a more uniform tension force when the chassis frame 5 is lifted. In this way, the energy consumption of the drive structure is reduced. Furthermore, the motor 8 and the circuits inside the chassis 6 do not require separate wiring for power supply, as they are all powered by the battery. This effectively achieves energy saving in the elevator and solves the problem in existing elevators where the cable cannot be properly adjusted according to the position of the personnel inside the chassis, resulting in uneven force on the chassis during lifting and excessive energy consumption of the traction motor, thus failing to achieve energy saving.

[0026] Based on the above, the specific framework structure can be found in [reference needed]. Figure 1 , Figure 2As can be seen, the frame structure includes a first mounting frame 1, a first chassis guide rail 2, a second mounting frame 3, a second chassis guide rail 4, and a stabilizing plate 22; wherein the two sets of first mounting frames 1 and the two sets of first chassis guide rails 2 are all securely connected by the stabilizing plate 22 and are installed on the elevator shaft by the stabilizing plate 22. The second chassis guide rail 4 is provided on the inner side of the stabilizing plate 22 located on the second mounting frame 3, and the first chassis guide rail 2 is provided on the inner side of the stabilizing plate 22 located on the first mounting frame 1. An auxiliary moving structure is movably provided on the surface of the first chassis guide rail 2, wherein the counterweight 12 is installed on the first mounting frame 1 and moves along the first mounting frame 1.

A movable plate 18 is provided on the surface of 11, and a movable wheel 21 is provided at the end of the movable plate 18. The pin shaft 19 passes through the movable plate 18. The surface of plate 19 is provided with a telescopic spring 20. One end of the telescopic spring 20 contacts the surface of the movable plate 18. When the chassis frame 5 is raised or lowered, in order to ensure the stability of the raising and lowering, the movable wheel 21 contacts the three sides of the chassis guide rail, which can better maintain the stability of the raising and lowering of the chassis frame 5. If there are foreign objects on the chassis guide rail, the movable wheel 21 can be effectively moved when it comes into contact with the foreign objects through the action of the telescopic spring 20, thereby further ensuring the stability of the chassis frame 5 when it is raised or lowered. It should be noted that the chassis guide rail needs to be inspected regularly to prevent cracks or foreign objects from appearing.

[0028] For details on the driving structure, please refer to [link / reference needed]. Figure 7 As can be seen, the drive structure includes a side frame 13, a fixed plate 14, and a traction motor 16. The side frame 13 is mounted on the surface of the first mounting frame 1 and the surface of the second mounting frame 3. A fixed plate 14 is connected between the two sets of side frames 13. The upper end surface of the fixed plate 14 is provided with a traction motor 16 and a cable sheave 15. The traction motor 16 is connected to a battery, and its cable is connected to the counterweight 12 through the cable sheave 15.

[0029] To ensure the elevator weighing sensor corresponds with the auxiliary moving structure and to guarantee the uniformity of force distribution on the chassis frame 5, please refer to [the relevant documentation]. Figure 3 and Figure 5 As can be seen, the chassis frame 5 is divided into four areas: A, B, C, and D.
