BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 1 is a schematic structural diagram of a wheelchair storage device of the present invention; Figure 2 It is a schematic cross-sectional structural diagram of the wheelchair storage device of the present invention. DETAILED DESCRIPTION

[0017] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0018] See also Figure 1 , 2 The embodiment of the present invention provides a wheelchair storage device, comprising a device fixing frame 1 for wall hanging, a swing connecting frame 2 and a storage rack 3 for storing and placing a wheelchair, wherein the device fixing frame 1 is provided with a traction device 4 for controlling the swinging movement of the swing connecting frame 2, and the storage rack 3 is connected to the swing connecting frame 2 to follow the swinging movement of the swing connecting frame 2 to produce a height change movement; Among them, the storage rack 3 includes a base frame 31 for carrying a wheelchair and suspension arms 32 arranged on both sides of the base frame 31; the swing connecting frame 2 includes a cantilever 21 for hanging the storage rack 3 and a connecting arm 22 hinged to the fixed frame 1 of the device, one end of the cantilever 21 is connected to the connecting arm 22, and the other end is hinged to the suspension arm 32, so that when the connecting arm 22 is driven by the traction device 4 to swing, the base frame 31 maintains a horizontal setting state.

[0019] Specifically, the traction device 4 includes a winding shaft 41, a traction belt 42 and a winding drive mechanism 43 for driving the winding shaft 41 to rotate. The fixed frame 1 of the device is provided with a winding shaft mounting seat 11 for installing the winding shaft 41; the winding drive mechanism 43 includes a gearbox for driving the winding shaft and a motor for driving the gearbox.

[0020] One end of the traction belt 42 is connected to the reel 41 , and the other end is connected to the swing connection frame 2 . The reel driving mechanism 43 controls the up and down swing of the swing connection frame 2 by driving the reel 41 to rotate.

[0021] Therefore, when the storage rack 3 needs to be folded up, the connecting arm 22 can be swung by rolling up the traction belt 42, thereby lifting the storage rack 3. Correspondingly, when the storage rack 3 needs to be lowered, only the traction belt 42 needs to be released, and the storage rack 3 can gradually fall to the ground under the action of gravity.

[0022] The device fixing frame 1 includes a wall frame 12 for connecting to a wall and a transverse extension beam 13 for hingedly connecting the connecting arm 22. The transverse extension beam 13 is arranged at the bottom of the wall frame 12 so that an equipment space for accommodating the traction device 4 is formed above the transverse extension beam 13.

[0023] The lateral extension beams 13 are provided on both sides of the bottom of the wall frame 12, and the connecting arms 22 are respectively hinged; a connecting cross bar 23 is connected between the two connecting arms 22, and the winding drive mechanism 43 is provided at a preset position of the equipment space, and after the connecting arm 22 swings to a preset angle, the connecting cross bar 23 conflicts with the winding drive mechanism 43, such as conflicting with the gearbox. Accordingly, the preset angle is the maximum storage angle.

[0024] Therefore, the interference limitation between the connecting cross bar 23 and the winding drive mechanism 43 can ensure that the overall center of gravity between the storage rack 3 and the swing connecting frame 2 is outward relative to the hinge between the connecting arm 22 and the transverse extension beam 13, which can ensure that the connecting arm 22 can use the weight of the storage rack 3 to always maintain a tendency to tilt and swing outward, thereby ensuring the unwinding operation of the traction device 4.

[0025] One end of the cantilever 21 is provided with a rotating shaft 24 for being hinged to the storage rack 3; the storage rack 3 includes a base frame 31 for carrying a wheelchair and hanging arms 32 arranged on both sides of the base frame 31, one end of the hanging arm 32 is hinged to the rotating shaft 24, and the other end is connected to the base frame 31.

[0026] The base frame 31 includes a fence 311 and a base for supporting a wheelchair. The fence 311 is provided at a preset position on the edge of the base to limit the movement of the wheelchair on the base.

[0027] Furthermore, in order to limit the movement of the wheelchair on the base, the base includes a plurality of bottom bars 312, the two ends of which are respectively connected to the two inner sides of the fence 311, and the fence 311 is provided with an entrance and exit 313 for the wheelchair to enter and exit the base. A preset spacing is left between adjacent bottom bars 312 to form a bayonet 314 for limiting the position of the wheelchair wheels. Therefore, the wheelchair can be restricted from sliding freely on the base by snapping the wheelchair into the bayonet 314.

[0028] On the other hand, in order to prevent the storage rack 3 from swinging due to unexpected external interference when in the storage state, such as strong wind or accidental small collision in extreme cases, a device activity channel 221 is provided in the connecting arm 22, a first magnetic object 5 is provided at the locking area in the device activity channel 221, and a second magnetic object 6 for attracting the first magnetic object 5 is provided on the bottom frame 31. When the connecting arm 22 swings to the maximum storage angle position, the first magnetic object 5 and the second magnetic object 6 are correspondingly adsorbed to each other to limit the swing of the storage rack 3.

[0029] Furthermore, in order to maximize the attraction between the first magnetic object 5 and the second magnetic object 6 while avoiding the inability of the gravity of the storage rack 3 to pull the first magnetic object 5 and the second magnetic object 6 apart due to excessive suction, the device fixed frame 1 is provided with an unlocking wire 7 of a preset length, and a steering wheel 222 is provided in the device active channel 221. One end of the unlocking wire 7 is connected to the device fixed frame 1, and the other end is connected to the first magnetic object 5 through the steering wheel 222 to suspend the first magnetic object 5; When the connecting arm 22 swings outward from the maximum storage angle position, the distance between the connecting arm 22 and the device fixing frame 1 will gradually increase, causing the unlocking line 7 to lift the first magnetic object 5, and the first magnetic object 5 will gradually break away from the locking area, causing the first magnetic object 5 and the second magnetic object 6 to be misaligned, and finally separated.

[0030] Preferably, the rotating shaft 24 is provided with a damping sleeve 8 for reducing the swinging of the hanging arm 32, and the damping sleeve is sandwiched between the hanging arm 32 and the cantilever 21 to increase the activity resistance of the hanging arm 32. Preferably, the damping sleeve is a rubber sleeve. Such a configuration can solve the problem of high-frequency oscillation of the storage rack 3.

[0031] Preferably, the device fixed frame 1 is provided with an anti-fall rope to prevent the swing connection frame from swinging down excessively, and the anti-fall rope is connected to the swing connection frame. More preferably, the device fixed frame is provided with a winding device for automatically winding up the anti-fall rope, and the winding device is a prior art, and its technical principle can refer to the existing common winding device of the tape measure.

[0032] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
