[0001] This utility model relates to the field of elevator car technology, specifically to an elevator car that is convenient for the elderly to get on and off. Background Technology

[0002] As the population ages, the safety and convenience of elevator use are increasingly becoming a concern for the elderly, who are one of the main users of elevators. Elevators, as an important vertical transportation tool in modern buildings, are widely used in residential buildings, hospitals, and commercial buildings, providing people with fast and convenient access to stairs. Traditional elevator car designs primarily focus on meeting the needs of general passengers, emphasizing space utilization and operational efficiency, with less consideration for special groups, especially the user experience and assistance needs of elderly people with mobility difficulties.

[0003] Existing elevator cars are usually equipped with simple handrails and seats, most of which are fixed and lack auxiliary structures designed for the elderly to get up. They cannot effectively alleviate the difficulties caused by the elderly's weakened muscles and stiff joints when standing up, resulting in poor safety and comfort during use. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, this utility model provides an elevator car that is easy for the elderly to get on and off, so as to solve the above problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an elevator car that facilitates the elderly to get on and off, comprising a car body, three auxiliary seats being provided on the innermost side wall of the car body, and three vertical mounting slots being provided on the innermost side wall of the car body. Each vertical mounting slot is equipped with a lifting drive component that works in conjunction with the auxiliary seats to assist in getting up. The lifting drive component includes a reduction motor installed at the top of the vertical mounting slot and a drive screw connected to the output end of the reduction motor. A screw sleeve is threaded onto the drive screw. The auxiliary seats are specifically installed on the front wall of the screw sleeve.

[0037] Please see Figure 1-7 An elevator car designed to facilitate elderly people's access to and from the elevator includes a car body 1, with three auxiliary seats 2 located on the innermost side wall. Each auxiliary seat 2 is correspondingly positioned within one of three vertical mounting slots 11 on the innermost side wall of the car body 1. Lifting drive components 3 are installed in the vertical mounting slots 11 to assist the auxiliary seats 2 in lifting operations to help them get up.

[0038] The lifting drive component 3 includes a geared motor 31 mounted at the top of the vertical mounting slot 11 and a drive screw 32 connected to the output end of the geared motor 31. A screw sleeve 33 is threaded onto the drive screw 32. The auxiliary seat 2 is specifically mounted on the front wall of the screw sleeve 33, so that the rotation of the drive screw 32 drives the screw sleeve 33 and the auxiliary seat 2 mounted thereon to rise and fall along the vertical mounting slot 11. Specifically, when the elderly person gets up, the geared motor 31 drives the drive screw 32 to rotate clockwise, thereby driving the screw sleeve 33 to move upward, thereby lifting the auxiliary seat 2 and supporting the lower body of the elderly person to get up. After the elderly person has finished getting up and walking away, the geared motor 31 receives a signal to perform the above reverse operation, driving the auxiliary seat 2 to fall back to the initial sitting position.

[0039] The auxiliary seat 2 includes a seat plate 23, the rear end of which is hinged to a transverse mounting bracket 21 located on the rear side via a hinge shaft 22. An electro-hydraulic push rod 24 is hinged to the top of the front tube wall of the transverse mounting bracket 21. The bottom end of the electro-hydraulic push rod 24 is hinged to the bottom end of the front tube wall of the lead screw sleeve 33, and the top end is hinged to the center of the bottom of the front side of the seat plate 23. The electro-hydraulic push rod 24 is used to retract the seat plate 23 when the passenger stands up. This tilting and retraction operation of the seat plate 23 can also adapt to the movement trajectory of the passenger's buttocks when standing up, assisting the passenger to stand up smoothly. Simultaneously, it retracts the seat plate 23 back to a horizontal position after standing up, facilitating seating operations for other elderly passengers.

[0040] Armrests 25 are installed on both the left and right sides of the horizontal mounting bracket 21. A button 26 is provided at the front end of the left armrest 25. The button 26 is wirelessly connected to the electric hydraulic push rod 24 and the reduction motor 31 to control the assisted sitting seat 2 to get up.

[0041] A pressure stress sensor 231 is installed at the center of the seat plate 23. This sensor detects changes in pressure from the occupant and connects wirelessly to the electro-hydraulic actuator 24 and the geared motor 31 to intelligently control the raising and lowering of the seat. Specifically, when the pressure stress sensor 231 does not receive pressure, it automatically sends a signal to the geared motor 31 and the electro-hydraulic actuator 24, causing them to move the seat plate 23 back to its initial horizontal position. Several anti-slip protrusions 232 are evenly distributed on the top surface of the seat plate 23 to improve safety while sitting and further enhance anti-slip properties to prevent slipping when getting up.

[0042] Guide rails 12 are provided on the left and right sides of each vertical mounting slot 11 on the innermost side wall surface of the car body 1. Guide components 4 are installed inside the guide rails 12. The guide components 4 include guide rods 41 installed inside the guide rails 12 and guide sleeves 42 slidably sleeved on the guide rods 41. The front wall of the guide sleeves 42 is fixedly connected to the auxiliary seat 2 to ensure the stability and smoothness of the auxiliary seat 2 during the lifting process.

[0043] Standing handrails 5 are installed on both the left and right side walls inside the car body 1 to provide support for passengers who need to stand, further improving the safety and comfort of the ride.
