Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent nursing apparatus, in particular to a triangular support accompanying platform and a use method thereof. BACKGROUND

[0002] The nursing platform is mainly used to solve the problems of the old people who are inconvenient to move and cannot take care of themselves, and provides the old people with help in sitting, lying, moving, auxiliary standing and turning over.

[0003] The Chinese patent with the publication number CN109730848A discloses a multifunctional nursing rehabilitation bed chair which can provide the functions of sitting, lying, auxiliary standing and turning over. However, the auxiliary standing is achieved by using a sitting-lying telescopic motor, and the left and right turning-over plates are embedded into a flat plate body through left and right staggered sawtooth square end surfaces. The turning-over of the left and right turning-over plates is achieved through a turning-over telescopic motor, a left pulling rope and a right pulling rope. Although the use requirements can be met, the auxiliary standing and turning over use two power components, which makes the overall structure more complex and the equipment cost higher.

[0004] In addition, due to the instability of the parallelogram, the existing accompanying platform with four supporting rods is similar to the above-mentioned patent document, that is, the four supporting rods of the platform are fixed and the power components of the auxiliary standing mechanism and the power components of the turning-over mechanism are structures of different power components, which makes the overall structure of the accompanying device more complex, the size larger and the cost higher.

[0012] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0013] Please refer to Figures 1 to 15 The embodiments provided by the present invention are as follows: A triangular support care platform, such as Figure 1 As shown, it includes a walking support module 1 and a functional module 2; The functional module 2 includes a seat cushion 22, which is a place for a person's buttocks and thighs to rest; like Figure 2 As shown, the walking support module 1 includes a base 15, electric push rod one 11, electric push rod two 12, electric push rod three 13, drive wheel 18, and omnidirectional passive wheel 14. The base 15 is placed horizontally. The electric push rods one 11, electric push rod two 12, and electric push rod three 13 are evenly distributed in a circumferential direction. The bottoms of the three electric push rods are evenly distributed on the same circumference, and the extension lines of the upper ends of the telescopic rods of the three electric push rods intersect at a point. The bottoms of the three electric push rods (in this article, the three electric push rods refer to electric push rod one 11, electric push rod two 12, and electric push rod three 13) are all connected to the ground. The bearing is hinged to the base 15, allowing the three electric actuators to swing inward or outward around the circumference. The center line of the bearing is tangent to the circumference. The top of the telescopic rods of the three electric actuators are connected to the bottom ball of the seat pad 22. This structure adopts a three-axis support structure, forming a triangular structure between two adjacent electric actuators and the base, which makes the support for the seat pad 22 more stable. The bearing allows the three electric actuators to swing inward or outward around the circumference, providing a flexible and interference-resistant structure, allowing the seat pad 22 to be used in a flexible manner within space.

[0014] Specifically, the electric push rod 11 is located at the right end of the base 15, the electric push rod 12 is located at the left end of the base 15, and the electric push rod 13 is located at the front end of the base 15; so that the three electric push rods can be conveniently adjusted to adjust the height of the right, left and front sides.

[0015] Specifically, the drive wheel 18 and the universal passive wheel 14 are both installed at the bottom of the base 15, making it easy for the care platform to move through intelligent control. The two drive wheels 18 are arranged opposite each other, and the two universal passive wheels 14 are arranged opposite each other.

[0016] Furthermore, the base 15 has a U-shaped top view with its opening facing the rear of the platform. This structure enables the subsequent development of a walking aid function mode, allowing the elderly to have enough space for their feet to move when they walk while holding onto the platform, and also allowing the care platform to be moved above the toilet for use.

[0017] Furthermore, such as Figure 3 As shown, the functional module 2 also includes a movable backrest 21 and a leg pad 26. The movable backrest 21 and the leg pad 26 are respectively hinged to the rear end and the front end of the seat pad 22, so that the functional module 2 can easily switch between bed and chair modes.

[0018] Furthermore, the front end of the movable backrest 21 is hinged to the rear end of the seat cushion 22, allowing the movable backrest 21 to rotate and be positioned within a range that allows it to be horizontally placed behind the seat cushion 22 and against the upper surface of the seat cushion 22. When the movable backrest 21 is horizontally placed behind the seat cushion 22, the user can be in a reclining position; when the movable backrest 21 is flipped to be against the upper surface of the seat cushion 22, it can be used to place items, or the platform can be shrunk in size and used as a walking aid.

[0019] Specifically, the functional module 2 further includes a flange 29 and a spring pin 210. The flange 29 is coaxially arranged with the hinge axis of the movable backrest plate 21 and the seat cushion plate 22, and the flange 29 is fixed on the movable backrest plate 21. The flange 29 has a plurality of circumferentially evenly arranged insertion holes. The spring pin 210 is slidably disposed on the seat cushion plate 22, and the spring pin 210 is inserted into one of the insertion holes. Through the cooperation of the flange 29 and the spring pin 210, the movable backrest plate 21 can be rotated and positioned within the range of horizontal placement and contact with the upper surface of the seat cushion plate 22 located behind it.

[0020] Further, the rear end of the leg cushion plate 26 is hinged to the front end of the seat cushion plate 22, and the leg cushion plate 26 can be positioned in a range from being horizontally placed at the front side of the seat cushion plate 22 to being vertically placed downward relative to the seat cushion plate 22. When the leg cushion plate 26 is horizontally placed at the front side of the seat cushion plate 22, the lower legs and feet of the user are lifted, and the user can use in a lying, semi-lying or sitting state; when the leg cushion plate 26 is vertically placed downward relative to the seat cushion plate 22, it is suitable for use in a sitting state with the lower legs drooping.

[0021] Specifically, the functional module 2 further comprises a fourth electric push rod 27 and a connecting rod 28, the fourth electric push rod 27 is fixed to the lower surface of the seat cushion plate 22, the telescopic rod of the fourth electric push rod 27 is hinged to the lower end of the connecting rod 28, and the upper end of the connecting rod 28 is hinged to the back of the leg cushion plate 26. Through the extension and retraction of the telescopic rod of the fourth electric push rod 27, the connecting rod 28 and the leg cushion plate 26 are swung, and the leg cushion plate 26 is positioned in a range from being horizontally placed at the front side of the seat cushion plate 22 to being vertically placed downward relative to the seat cushion plate 22.
