The first linear driver 54a and the second linear driver 54b preferably adopt electric push rods.
[0032] The first linear driver 54a and the second linear driver 54b simultaneously push the first telescopic swing arm 52a and the second telescopic swing arm 52b to move up and down around the fulcrum end, thereby driving the waist guard 53 to move up and down together, and further pass the waist guard 53 exercises to assist the user to get up and stand, and at the same time, the waist protector 53 can also rotate flexibly following the movement of the user's upper body.
[0033] The knee support mechanism 6 includes a first knee support 6a and a second knee support 6b in the shape of a "U" groove, which are respectively fixed on the secondary rods of the first telescopic swing arm 52a and the second telescopic swing arm 52b. It can be adjusted up and down according to the extension and contraction of the secondary rods of the first telescopic swing arm 52a and the second telescopic swing arm 52b, so that the height of the knee support mechanism 6 can also be adjusted according to the height of the user's knee or calf. The knee support mechanism 6 is mainly used to prevent bending of the knee and assist the user's calf to achieve standing.
[0034] The buttocks support mechanism 7 includes a third drive mechanism 71a, a fourth drive mechanism 71b, a first binding belt 72a, a second binding belt 72b, and a buttocks support pad 73. The third drive mechanism 71a and the fourth drive mechanism 71b are respectively fixed on both sides of the upper part of the fixed bracket. One end of the first binding belt 72a is connected with the third drive mechanism 71a, and the other end passes through the fulcrum end of the first telescopic swing arm 52a. Enter and pass through the opening provided on the secondary rod of the first telescopic swing arm 52a, and movably connect with one end of the buttocks support cushion 73 after passing through; similarly, one end of the first binding strap 72b is connected to the fourth driving mechanism 71b. Connected, the other end penetrates through the fulcrum end of the second telescopic swing arm 52b and exits through the opening provided on the secondary rod of the second telescopic swing arm 52b, and is movably connected to the other end of the buttocks support cushion 73 after passing out.
[0035] Preferably, the first binding belt 72a and the buttocks support cushion 73 are connected by a buckle, that is, the end of the first binding belt 72a is provided with a buckle, and the buckle is buckled in the buckle groove at one end of the buttocks support cushion 73 to form a detachable connection ; Similarly, the second binding belt 72b and the buttocks support cushion 73 are connected by a buckle, that is, the end of the second binding belt 72b is provided with a buckle, and the buckle is buckled in the buckle groove at the other end of the buttocks support cushion 73 to form a Disconnect the connection.
[0036] More preferably, the first binding strap 72a and the buttocks support pad 73 are connected by a turn buckle, that is, the end of the first binding strap 72a is tied with a turn buckle, and the turn buckle is buckled in the turn button hole at one end of the buttocks support pad 73 to form a detachable Movable connection; Similarly, the second binding strap 72b and the buttocks support pad 73 are connected by a turnbuckle, that is, the end of the second binding strap 72b is tied with a turnbuckle, and the turnbuckle is buckled in the turnbuckle hole at the other end of the buttocks support pad 73, Form a detachable movable connection.
[0037] The third driving mechanism 71a and the fourth driving mechanism 71b respectively drive the first binding belt 72a and the second binding belt 72b to tighten or relax the buttocks support cushion 73, so that the buttocks support cushion 73 can support the user's buttocks and further stabilize This improves the user’s standing posture, prevents the user from squatting, and also improves the user’s comfort.
[0038] Such as Figure 4 As shown, the user can operate the scooter 100 to switch between sitting and standing positions. When the user needs to operate the scooter 100 of the present invention to switch from a sitting position to a standing position, the user first removes the waist guard 53 and buttocks The support pad 73 is then placed under the buttocks and the waist support 53 is connected to the ends of the first telescopic swing arm 52a and the second telescopic swing arm 52b from behind the waist.
[0039] Secondly, the user puts his feet on the footrest 14 while twisting the integrated controller 43 to control the third driving mechanism 71a and the fourth driving mechanism 71b to reverse, thereby shortening the first binding belt 72a and the second binding belt 72b to Place the hip support pad 73 close to the user’s buttocks, and then close the calf or knee to the "U"-shaped grooves of the first knee support 6a and the second knee support 6b, while the user grasps the handle with his hand 32.
[0040] Finally, the user presses the second drive mechanism controller 33 with his right thumb to control the second drive mechanism 54 to push the "T"-shaped transmission shaft 54b to rotate and drive the first telescopic swing arm 52a and the second telescopic swing arm 52b to swing upwards. The arm movement simultaneously drives the waist guard 53 and the buttocks support cushion 73 to support the user’s waist and buttocks, thereby completing the user’s transition from a sitting state to a standing posture and can continue to maintain a standing state, and further the user can use the integrated controller 43. Control the first driving mechanism 15 to drive the front wheel assembly 12 to make the scooter 100 of the present invention walk forward. The user can drive the scooter 100 to achieve forward, backward and turning operations. In addition, the first drive of the scooter 100 of the present invention The mechanism 15, the second drive mechanism 54, the third drive mechanism 71a, and the fourth drive mechanism 71b can all realize the self-locking function when in the stopped state, thereby effectively ensuring the personal safety of the user.
[0041] When the user is not using the scooter 100, he only needs to press the second driving mechanism controller 33 with his right thumb to control the first telescopic swing arm 52a and the second telescopic swing arm 52b to produce downward swinging arm movement, and at the same time under the weight of the body Under compression, the first telescopic swing arm 52a and the second telescopic swing arm 52b are gradually shortened, and the waist guard 53 and the buttocks support cushion 73 will also slowly swing downwards, and the end user will slowly change from standing to sitting and from standing. Just release your right thumb after sitting. Furthermore, the integrated controller 43 can be twisted to control the third drive mechanism 71a and the fourth drive mechanism 71b to rotate forward so that the buttocks support pad 73 is in a relaxed state so that the buttocks support pad 73 can be removed, and then the waist support 53 is removed and the calf is removed If the board 14 is taken off, the scooter 100 can be separated.
[0042] In summary, the user driving the scooter 100 of the present invention can switch between sitting and standing positions at will, and the user can complete daily activities such as cooking, dining, and going to the toilet on the scooter 100 to realize self-care . After being fixed on the scooter 100, the user can also use the auxiliary standing mechanism to repeatedly sit and stand to perform simple rehabilitation squatting training for the legs. Finally, a scooter 100 for the disabled of the present invention has the advantages of ingenious design, compact structure, simple operation, safety and stability.
