Description

Technical Field

[0001] This utility model relates to the field of elevator product technology, and in particular to a concealed villa elevator track and operating mechanism. Background Technology

[0002] Concealed villa elevators are a modern, space-saving elevator design, typically made of transparent acrylic material, with a smooth appearance that blends seamlessly with home décor. They have the following characteristics:

[0003] (1) Shaftless design: This type of elevator does not require a traditional shaft or pit, combining safety and aesthetics.

[0004] (2) Customization options: The appearance and materials of the elevator can be customized according to the home decoration style, providing a variety of style options.

[0005] (3) Applicability: Suitable for villas of different heights, flexible installation, and able to meet the actual needs of families.

[0006] There are two types of shaftless elevator designs: one uses a framed enclosure with transparent glass or acrylic to replace the shaft; the other has no enclosure at all. Currently, these elevator designs are modifications of existing elevators and require load-bearing walls, including the load-bearing walls on which the tracks are installed.

[0007] It is evident that existing shaftless concealed villa elevators have drawbacks, such as requiring load-bearing walls to install the tracks, and the need to find additional space for the control box.

[0008] To overcome the aforementioned problems, we have invented a concealed villa elevator track and operating mechanism. Utility Model Content

[0009] The purpose of this invention is to solve the problems of existing shaftless concealed villa elevators, which require load-bearing walls to install the tracks and also require additional space for the control box. The specific solution is as follows:

Detailed Implementation

[0044] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0045] like Figures 1 to 7 As shown, a concealed villa elevator includes a track and operating mechanism, comprising a gantry assembly that passes through each floor and is vertically fixedly connected to the floor level (e.g., in this embodiment, it is a two-story building, including a first floor 10 and a second floor 11), and a car 20 located inside the gantry assembly and capable of vertical movement. The gantry assembly includes a left guide rail 12 and a right guide rail 13 that are parallel and symmetrical on both sides, and a crossbeam 14 located at the top of the left and right guide rails 12 and fixedly connected thereto. A control box 21 is located on the top of the car 20. The control box 21 contains a control circuit board assembly 22 (including multiple circuit boards, single-chip microcomputers, and various components, which are prior art and will not be described in detail here) and a traction mechanism and a safety mechanism electrically connected thereto. Sliding mechanisms are located on the left and right sides of the car 20, sliding up and down along the left and right guide rails 12 and 13, and the sliding mechanisms include stabilizing mechanisms. For aesthetic purposes, a decorative panel (not shown in the figure) can be installed on the upper side of the crossbeam 14. Preferably, the crossbeam 14 is made of 5mm thick steel plate. The left guide rail 12 and the right guide rail 13 are made of 4mm thick aluminum profile.

[0046] Specifically, the car 20 is equipped with a double-door mechanism with parallel front and rear openings. The front and rear bottoms of the car 20 have entry ramps 23, which move up and down with the car 20. The left and right sides of the car 20 are pillow-shaped 24, which facilitates the installation of the left guide rail 12 and the right guide rail 13. The ramps 23 facilitate the entry and exit of wheelchairs, trolleys, or strollers.

[0047] Specifically, the traction mechanism includes a drive mechanism located at the rear of the control box 21, a rotating mechanism rotatably connected thereto, and a hoisting mechanism located at the left and right ends of the rotating mechanism and on the left and right sides of the car 20.

[0048] Specifically, the drive mechanism includes a motor 25 and an encoder 26 connected thereto, and the motor 25 and encoder 26 are electrically connected to the control circuit board assembly 22.

[0049] Specifically, the rotating mechanism includes a gearbox 27 rotatably connected to the main gear of the motor 25 (not shown in the figure) and a rotating shaft 28 rotatably connected to the gearbox 27.

[0050] Specifically, the winch mechanism includes a left winch 29 and a right winch 30 located at the left and right ends of the rotating shaft 28. A left wire rope 31 can be wound on the left winch 29, and the lower end of the left wire rope 31 (via two dedicated safety buckles 33 and a protrusion 34) is fixed to the inside of the left winch 29 (e.g., Figure 7 As shown), the upper end of the left wire rope 31 (hexagonal nut 35, spring washer 36 and safety pin 37) is fixed to the left end of the crossbeam 14. The right wire rope 32 can be wound on the right winch 30. The lower end of the right wire rope 32 is fixed to the inside of the right winch 30, and the upper end of the right wire rope 32 is fixed to the right end of the crossbeam 14.

[0051] Specifically, the safety mechanism includes an upper safety disc 38 on the top surface of the control box 21, a lower safety disc 39 on the lower side of the bottom surface of the car 20, a left anti-loosening device 40 and a left brake 42 on the left side of the wire rope 31, a right anti-loosening device 41 and a right brake 43 on the right side of the wire rope 32, an overspeed protector 44 near the left winch 29 of the control box 21, and a safety fence (not shown in the figure) in the entrance and exit area of ​​the car 20 above the second floor. The safety fence is to prevent children and adults from accidentally entering the floor openings (for the car 20 to pass through floors) in the entrance and exit area and falling to the ground, causing personal accidents.

[0052] Specifically, a switch (not shown in the figure) is provided on the lower side of the upper safety disc 38 and the lower safety disc 39, respectively. The switch is electrically connected to the control circuit board assembly 22. The switch can be a mechanical touch switch or a proximity switch, depending on the specific situation and the environmental conditions of the place of use. The function of the switch is to generate a protection signal when the upper safety disc 38 and the lower safety disc 39 approach or hit an obstacle, and transmit it to the microcontroller chip in the control circuit board assembly 22. The microcontroller chip then issues a command to control the car 20 to stop running, and resumes running after the obstacle is removed.

[0053] Specifically, the overspeed protector 44 is electrically connected to the control circuit board assembly 22. The overspeed protector 44 operates synchronously with the toothed belt 46, which is located at the upper and lower ends of the left guide rail 12 and wraps around the synchronous speed measuring wheel 45. Simultaneously, the overspeed protector 44, through its braking mechanism (not shown in the figure), can drive the left brake 42 and right brake 43 for braking. To ensure that the toothed belt 46 can smoothly wrap around the synchronous speed measuring wheel 45, a guide wheel 47 and a tension wheel 48 are also provided. For ease of observation, the toothed belt 46 between the tension wheel 48 and the synchronous speed measuring wheel 45 is omitted from the figure. When the overspeed protector 44 detects overspeed, the microcontroller chip in the control circuit board assembly 22 immediately issues a stop command, causing the braking mechanism to extend and rotate the brake plate 50 on the brake linkage 49, thus rotating the brake linkage 49 and driving the left brake 42 and right brake 43 for braking. The brake wheels 53 in the left brake 42 and right brake 43 are tightly locked against the left guide rail 12 and right guide rail 13 respectively, stopping the car 20. The overspeed protector 44 and encoder 26 are both existing technologies, and their specific working principles will not be described in detail here.

[0054] Specifically, the sliding mechanism includes upper pulley assemblies located on the upper left and right sides of the car 20 and lower pulley assemblies located on the lower left and right sides of the car 20. The upper pulley assemblies include a left rear corner wheel 54 and a front corner wheel 55 on the left and rear sides, respectively. The lower pulley assemblies include a left rear corner wheel and a left side wheel (not shown in the figure), and a right rear corner wheel 54 and a right side wheel 56. The rear corner wheel 54 and the front corner wheel 55 are slidably connected to the rear corner rail 57 and the front corner rail 58 of the left guide rail 12 and the right guide rail 13, respectively. The left side wheel is slidably connected to the left side rail of the left guide rail (not shown in the figure), and the right side wheel 56 is slidably connected to the right side rail 59 of the right guide rail 13. The stabilizing mechanism is used to stabilize the running posture of the car 20 along the left guide rail 12 and the right guide rail 13. The stabilizing mechanism is composed of the rear corner wheel 54 and the front corner wheel 55, and the left side wheel and the right side wheel 56.

[0055] The elevator car door 60 is made of transparent acrylic, providing excellent visibility. The car 20 is equipped with an emergency stop button and a call button (not shown in the diagram) for timely response to emergencies. The control panel 51 (located on the right side inside the car 20, featuring commonly used floor numbers, up, down, etc. buttons) has an LED light strip (not shown in the diagram) mounted on its side, adding a touch of warmth. The car frame 61 is made of aluminum alloy profiles, facilitating processing and installation. It features a painted finish, allowing for custom color selection. When the elevator is not in use, the car 20 automatically stops at the second floor, hence the name "invisible elevator." To prevent power outages, a backup power supply 52 is located on the left side of the control circuit board assembly 22. The car door 60 can be opened manually or automatically. Manual opening allows for escape in emergencies, while automatic opening allows for escape by breaking down the door.

[0056] In summary, the technical solution of this utility model has the following beneficial effects:

[0057] This utility model has the following advantages:

[0058] 1. The problem of not needing load-bearing walls is solved by using gantry frame components;

[0059] 2. When there is no pit, the ramp device moves with the car, which solves the problem that the ramp device on the fixed ground would obstruct the daily activity area.
