Description

Technical Field

[0001] The utility model relates to a vehicle for the elderly, in particular to a vehicle for the elderly that can be folded up and down. Background Art

[0002] Existing elderly vehicles are generally foldable wheelchairs, which are folded left and right to reduce the size in the horizontal direction and achieve the purpose of reducing the volume.

[0003] For example, the vehicle for assisting the elderly in walking and providing rest is disclosed in the patent with publication number CN2551232Y, and the vehicle frame is capable of being folded or unfolded forward and backward by means of a folding and retracting frame.

[0004] The above-mentioned elderly stroller is folded horizontally by a folding and retracting frame, thereby reducing the horizontal size and volume. However, in actual applications, the horizontally folding elderly stroller is easy to tip over after folding and needs to lean against a fixed object or wall, resulting in low stability.

[0005] Therefore, there is an urgent need for a foldable bicycle for the elderly to improve the stability during storage. Utility Model Content

[0030] Reference Figures 1 to 7A foldable elderly stroller includes a body, which has an unfolded state and a folded state. The body is composed of a bracket 2 and a seat frame 1. The seat frame 1 is hinged to the bracket 2 through a rotating shaft 3. The rotating shaft 3 is long and arranged in the left and right directions. The seat frame 1 can rotate around the rotating shaft 3 in a vertical plane. The seat frame 1 rotates relative to the bracket 2, so that the body can be folded up and down, reducing the vertical size.

[0031] In a preferred embodiment, a first positioning portion 13 is provided on the seat frame 1, and a second positioning portion 22 adapted to the first positioning portion 13 is provided on the bracket 2, and the first positioning portion 13 and the second positioning portion 22 are detachably connected; when the vehicle body is in the unfolded state, the first positioning portion 13 cooperates with the second positioning portion 22 and is fixedly connected together, thereby improving the structural stability of the vehicle body in the unfolded state and preventing the seat frame 1 and the bracket 2 from rotating relative to each other.

[0032] In a preferred embodiment, the first positioning portion 13 includes a positioning rod 131 and a telescopic shaft 1314 installed inside the positioning rod 131, the positioning rod 131 is long and arranged in the left and right directions, and the end of the positioning rod 131 is provided with a first axial hole 1313, the telescopic shaft 1314 can be fed and moved on the first axial hole 1313, and the telescopic shaft 1314 can extend outward from the positioning rod 131 through the first axial hole 1313; the second positioning portion 22 includes a second axial hole 221, and the telescopic shaft 1314 is adapted to the second axial hole 221; when the vehicle body is in the unfolded state, the telescopic shaft 1314 extends out of the first axial hole 1313 and is inserted into the second axial hole 221, thereby fixing the seat frame 1 and the bracket 2 relatively to prevent the seat frame 1 and the bracket 2 from rotating relative to each other.

[0033] In a preferred embodiment, a pulling member 132 is installed on the positioning rod 131, and the pulling member 132 includes a traction portion 1322 and a traction portion 1321. A mounting hole 1311 is provided on the side wall of the positioning rod 131, and the traction portion 1322 passes through the mounting hole 1311 to enter the interior of the positioning rod 131 and is transmission-connected (fixedly connected) to the telescopic shaft 1314. The traction portion 1321 is located outside the positioning rod 131. By pulling the traction portion 1321 from the outside, the traction portion 1321 lifts the traction portion 1322, and the traction portion 1322 pulls the telescopic shaft 1314, so that the telescopic shaft 1314 disengages from the second axis hole 221, and the seat frame 1 and the bracket 2 are converted into a relatively rotatable state, so that the vehicle body can be switched to the folding state.

[0034] In some embodiments, the left and right ends of the positioning rod 131 are both provided with the first axial hole 1313, the number of the telescopic shafts 1314 is two and they are respectively installed on the left and right ends of the positioning rod 131; the number of the traction parts 1322 is two and they are arranged on the left and right sides of the pulling part 1321, the number of the mounting holes 1311 is two and they are arranged in the middle of the positioning rod 131, and the two traction parts 1322 are respectively connected to the left and right telescopic shafts 1314 through the two mounting holes 1311.

[0035] In some embodiments, the telescopic shaft 1314 includes a telescopic pin, a spring, and a fixed rod. The fixed rod is fixedly connected to the positioning rod 131. One end of the spring is fixedly connected to the fixed rod, and the other end of the spring is elastically connected to the telescopic pin. When the pulling member 132 is pulled, the telescopic pin retracts and compresses the spring. When the pulling member 132 is released, the spring recovers and partially ejects the telescopic pin out of the first shaft hole 1313 (a limit plate is provided on the telescopic pin, which abuts the inner side of the first shaft hole 1313).

[0036] In some embodiments, the positioning rod 131 is parallel to the rotating shaft 3 and is located at the rear side of the rotating shaft 3 .

[0037] In a preferred embodiment, the second positioning portion 22 further includes a limiting plate 222 . When the vehicle body is in the unfolded state, the positioning rod 131 abuts against the upper portion of the limiting plate 222 , thereby improving the structural stability in the unfolded state.

[0038] In some embodiments, the positioning rod 131 is welded to the bottom of the seat frame 1 .

[0039] In a preferred embodiment, a flexible gasket 1312 is installed on the inner wall of the mounting hole 1311 to reduce the wear of the pulling member 132 on the positioning rod 131 .

[0040] In some embodiments, a limiting rod 23 is provided on the bracket 2. When the seat frame 1 rotates to a certain angle (in a folded state), the seat frame 1 abuts against the limiting rod 23 to limit further rotation of the seat frame 1.

[0041] In some embodiments, a first hinge seat 11 is provided on the left and right sides of the lower end of the seat frame 1, and a second hinge seat 21 corresponding to the first hinge seat 11 is provided on the left and right sides of the upper end of the bracket 2, and the first hinge seat 11 and the second hinge seat 21 are hinged together through the rotating shaft 3.

[0042] The above are only preferred embodiments of the present invention and do not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or directly or indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
