Description

A detachable mobile chassis for nursing beds and chairs

technical field

The invention relates to the field of elderly care and assistance for the disabled, and is especially suitable for the elderly, weak, inconvenient, paralyzed and semi-paralyzed people.

Background technique

There are many types of smart wheelchairs, which are designed to provide assisted rehabilitation, living, rest and activities within a certain range for the elderly, infirm or disabled. The ability of the elderly to move by themselves is relatively poor, especially the frequent transfer from bed to wheelchair and from wheelchair to bed is a relatively big trouble in life. With the birth of various nursing beds, in order to meet the needs of the care recipients Space transfer, changing of sleeping and sitting positions, toilet care and other issues, the detachable mobile chassis for nursing beds and chairs is also urgently needed to be developed.

Contents of the invention

In order to develop a detachable mobile chassis for nursing beds and chairs, the present invention changes the integrated structure of the previous intelligent wheelchair, and makes the seat part and the mobile chassis into relatively independent modules. The seat part can complete the automatic docking action with the nursing bed body, and the mobile chassis part can be separated from the main part of the seat, providing sufficient space for the nursing device to meet the multiple needs of the nursing device for defecation collection, washing, drying, disinfection, etc. Integration of functions.

The technical solution adopted by the present invention to solve its technical problems is: the present invention discloses a detachable mobile chassis facing nursing beds and chairs, which includes a chassis frame, omnidirectional casters, a guiding mechanism that cooperates with the main body of the seat, and a locking mechanism. mechanism, steering mechanism, lifting mechanism. The chassis frame is welded by square tubes, and the mobile chassis includes four omnidirectional casters, two of which are free-steering wheels, and the other two are controlled by the steering mechanism. The guiding mechanism is composed of a guiding column and a supporting plate of the guiding column. The locking mechanism is composed of a locking clip and a locking clip connector. The steering mechanism includes a shaking handle, a bevel gear transmission system, a rack and pinion transmission system, a slide rail assembly, and a lifting mechanism. It consists of a lifting column and a lifting column support plate.

The above-mentioned detachable mobile chassis for nursing beds and chairs, when the mobile chassis needs to enter the bed body to carry the seat, the steering mechanism controls the omnidirectional wheels to turn to enter the bed body, and when the mobile chassis enters the designated position of the bed body, the lifting mechanism lifts After the chassis and the seat are docked, the locking mechanism is manually locked, and the mobile chassis completes the composition with the wheelchair. The invention solves the problem of inconvenient movement of the care receiver, saves the burden of frequent transfers from the bed to the wheelchair and from the wheelchair to the bed, and at the same time solves the problem that the nursing device cannot realize various Relatively complete functions.

The beneficial effect of the present invention is that the present invention not only solves the problem of transferring the care receiver from the bed to the wheelchair through a scheme of a detachable mobile chassis facing the nursing bed chair, but also solves the problem of insufficient space at the bottom of the traditional seat, Due to the narrow space under the bed and chair, the traditional bed and chair cannot realize the functions of perfect defecation treatment and post-defecation care due to the space limitation after having the seat movement function. Using this solution can perfectly solve the problem of chassis mechanism and nursing device. conflict.

detailed description

The present invention will be further described below in conjunction with accompanying drawing and embodiment:

The structures, proportions, sizes, quantities, etc. shown in the drawings attached to this specification are only used to match the content disclosed in the specification, for those who are familiar with this technology to understand and read, and are not used to limit the implementation of the present invention. Limiting conditions, so there is no technical substantive meaning, any modification of structure, change of proportional relationship or adjustment of size, without affecting the effect and purpose of the present invention, should still fall within the scope of the present invention. The disclosed technical content must be within the scope covered. At the same time, terms such as "upper", "lower", "left", "right", and "middle" quoted in this specification are only for the convenience of description and are not used to limit the scope of the present invention. , the change or adjustment of its relative relationship, without substantive changes in the technical content, should also be regarded as the scope of the present invention that can be implemented.

【Example】

The invention discloses a detachable mobile chassis facing nursing beds and chairs, comprising a chassis frame 1, omnidirectional casters 2, a guiding mechanism 3 cooperating with the main body of the seat, a locking mechanism 4, a steering mechanism 5, and a lifting mechanism 6 . The chassis frame 1 is welded by square tubes, and the mobile chassis includes four omnidirectional casters 2, two of which are free steering wheels 22, and the other two are steering mechanism 5 control steering wheels 21. The guide mechanism 3 is composed of a guide column 31 and a guide column support plate 32. The locking mechanism 4 is composed of a locking clip 41 and a locking clip connector 42. The steering mechanism 5 includes a shaking handle 51, a bevel gear train 52, a rack and pinion Drive train 53, slide rail assembly 54, lifting mechanism 6 is made up of lifting column 61, lifting column support plate 62.

In this embodiment, when the above-mentioned detachable mobile chassis facing the nursing bed chair needs to enter the bed body to carry the seat, the steering mechanism 5 controls the omnidirectional casters 21 to turn to enter the bed body. When the mobile chassis enters the designated position of the bed body, Lifting mechanism 6 rises, and guiding mechanism 3 guides, and after chassis and seat part 7 are docked, locking mechanism 4 is manually locked, and the combination of mobile chassis and seat part 7 is completed.

In this embodiment, the above-mentioned detachable mobile chassis facing the nursing bed chair is used without power (those skilled in the art can understand that when the chassis enters the bed body, it needs to be pulled by a traction mechanism or pushed by a person to provide power), When the self-powered chassis is used, it does not need to be pulled by a traction mechanism or pushed by people to provide power, and the choice is made according to actual needs, and the specific execution method is not limited.

The beneficial effect of the present invention is that the present invention not only solves the problem of transferring the care receiver from the bed to the wheelchair through a scheme of a detachable mobile chassis facing the nursing bed chair, but also solves the problem of insufficient space at the bottom of the traditional seat, Due to the narrow space under the bed and chair, the traditional bed and chair cannot realize the functions of perfect defecation treatment and post-defecation care due to the space limitation after having the seat movement function. Using this solution can perfectly solve the problem of chassis mechanism and nursing device. conflict.
