Description

A toilet seat cushion lift and its automatic control method

Technical field

The invention relates to a toilet seat cushion lift and an automatic control method thereof.

Background technique

Some toilets for the elderly or people with limited legs and feet are basically equipped with armrests on both sides of the toilet to facilitate users to use them when sitting down/squatting or standing up. However, these armrests are fixedly installed and there is no way to automatically lift the user. Support cannot provide users with more convenience. For this reason, there are some toilet auxiliary devices that can automatically lift on the market. However, these devices currently have relatively complex structures, especially their traditional structures. In order to be able to lift smoothly, It is often necessary to be equipped with multiple drive motors and connectors, and each motor and connector is required to be lifted and lowered synchronously. During assembly, it is easy to have difficulty in adjustment and uncoordinated movements. When in use, it is easy to be damaged and difficult to maintain. The problem of high costs.

Contents of the invention

In order to solve the above technical problems, the present invention proposes a toilet lifting structure with simple structure and relatively low installation and use costs.

In the first aspect, a toilet seat lift is provided, including a fixed support, a movable support and a driving component, wherein,

The fixed support is provided with a horizontal U-shaped opening, and the movable support is movably arranged on the top of the fixed support.

There are two groups of driving assemblies, both of which include link mechanisms and driving parts.

The linkage mechanism adopts a four-link structure, is arranged in a vertical direction, and includes a first link and a second link. The first connecting rod and the second connecting rod each include a fixed end and a movable end. The fixed ends of the first connecting rod and the second connecting rod are both rotatably installed on the side of the fixed support. The first connecting rod and the second connecting rod include a fixed end and a movable end. The movable ends of the second connecting rod are rotatably mounted on the side of the movable support.

During operation, the driving member connection drives the first connecting rod to swing around the fixed end, thereby driving the movable support to move up and down through the link mechanism.

By arranging a driving assembly with a four-link structure, the present invention not only has a simple structure, but also can uniformly drive one side of the movable support to move up and down on two support points through the rotation of one connecting rod. The drive proposed by the invention The components also have the advantages of simple assembly, low debugging difficulty and low maintenance difficulty.

Preferably, the first link and the second link are parallel and equal in length, and the movable support always remains horizontal during the up and down movement, providing reliable support for the user.

Preferably, the distance between the two fixed ends is greater than the distance between the two movable ends, and the two movable ends are closer to the front end of the entire elevator than the two fixed ends. The movable support is in a horizontal state when it is at the lowest position, and when it is above It gradually tilts during the movement. At the highest position, the rear end of the movable support is higher than the front end, which can help the user gradually stand up.

Preferably, the fixed support includes a main body, fixed side plates, armrests and supporting legs. The U-shaped opening is opened on the main plate. There is a pair of fixed side plates, which are symmetrically arranged on both sides of the main plate. The armrests There are also a pair, respectively installed on the two fixed side panels. The armrest is provided with a control switch for controlling the driving assembly. The armrest is provided with a control switch for controlling the driving assembly. The support legs are provided at the bottom of the two fixed side plates.

Preferably, the movable support plate includes a seat plate and movable side plates, the seat plate is provided with an O-shaped hole, and there is a pair of movable side plates, which are symmetrically arranged on both sides of the seat plate.

Preferably, the two movable side plates are located outside the two fixed side plates. The linkage mechanism is installed between the movable side plate and the fixed side plate.

Preferably, the link mechanism further includes a connecting plate, the fixed ends of the first connecting rod and the second connecting rod are pre-installed on the connecting plate, and the connecting plate is installed on the outside of the fixed side plate.

Preferably, a side portion of the first link is provided with a downwardly extending driving part, and the driving part includes a power component and a telescopic rod. The power component is swing mounted and connected to drive the telescopic rod to telescopically move. The terminal end of the telescopic rod is hingedly connected to the driving part of the first connecting rod.

Preferably, the power component is a hydraulic cylinder, a pneumatic cylinder or a telescopic motor. The rear side of the fixed support is provided with hanging ears extending downward, and the rear end of the power component is suspended and installed on the hanging ears.

In a second aspect, an automatic control method for a toilet seat cushion lift is provided, using the toilet seat cushion lift described in any one of claims 1 to 9. During the rising process of the toilet seat lift, the current of the driving component is collected. When the current current is less than the preset value, or when the current current is less than the preset percentage of the initial current, it is determined that the user can independently complete the subsequent standing process. and action to end the rising action of the driving assembly, to prevent the movable support that continues to rise from being too high and unfavorable for the user to stand up, or to prevent the movable support that moves forward from pushing the user down.

From the above description of the present invention, it can be seen that the present invention has the following beneficial effects:

By arranging a driving assembly with a four-link structure, not only the structure is simple, but also the rotation of one connecting rod can uniformly drive one side of the movable support to move up and down on two support points. The driving assembly proposed by the present invention also It has the advantages of simple assembly, low debugging difficulty and low maintenance difficulty;

By adjusting the installation state between the first link and the second link, you can choose to keep the movable support horizontal during the lifting process, or you can choose to have the movable support gradually turn forward during the lifting process. , providing consumers with multi-faceted services;

By collecting the current changes of the driving component during the rising process, when it is judged that the user can complete the subsequent standing action independently, the rising action of the movable support is stopped, which can avoid the problem that the movable support is too high, making it difficult for the user to stand, or, also, This can prevent the movable support from turning forward too much and pushing the user down.
