Referring to fig. 9, in some other embodiments, the cushion pad 70 is connected to the mounting portion 11 of the mounting base 10, when the swing arm 41 is in the retracted state, the cushion pad 70 abuts against the swing arm 41, and when the swing arm 41 is switched from the to-be-retracted state to the retracted state, the swing arm 41 can be prevented from directly colliding with the mounting portion 11 under the action of the reset element.

The implementation principle of the auxiliary boarding device in the embodiment is as follows: the mounting base 10 and the mounting box 31 in the auxiliary boarding device are fixedly arranged on a balance scooter or other similar running device. In the initial state, the swing arm 41 in the auxiliary boarding device is in a contracted state, and the rotation stop block 20 is in an unlocked state. At this time, the swing arm 41 is separated from the rotation stop block 20, and the elastic hook 36 in the brake mechanism 30 engages with the second limiting step 327.

The swing arm 41 is opened by using external force (can be in a mode of electric drive or manual mechanical potential energy) to enable the swing arm 41 to be in a release state, and in the opening process of the swing arm 41, the swing arm 41 props against the rotation stopping block 20 to enable the rotation stopping block 20 to be switched from an unlocking state to a locking state, so that the rotation stopping block 20 is in clamping fit with the swing arm 41, and the function of supporting a balance scooter or other similar running devices is achieved.

When the swing arm 41 and the rotation stopping block 20 are switched from the separated state to the clamped state, the rotation stopping block 20 drives the moving block 32 to move, the moving block 32 moves upwards, at this time, the elastic clamping hook 36 abuts against the second guide inclined plane 335 in the guide limiting block 328, the elastic clamping hook 36 deforms towards the side of the switching channel 60 under the action of the second guide inclined plane 335, and the elastic clamping hook 36 is clamped with the first limiting step 326 under the action of elastic potential energy of the reset spring 35, so that the rotation stopping block 20 and the swing arm 41 are clamped and matched.

When a user gets on the vehicle, the gravity is applied to the balance scooter or other similar travelling devices, and acts on the swing arm 41 to enable the swing arm 41 to move towards the swing gap 50, and the swing arm 41 abuts against the rotation stopping block 20 in the swing process, so that the rotation stopping block 20 drives the moving block 32 to move. At this time, the rotation stopping block 20 is firstly switched from the locked state to the to-be-unlocked state, and then is switched from the to-be-unlocked state to the unlocked state, that is, the rotation stopping block 20 is separated from the limiting engagement of the swing arm 41, and the swing arm 41 is reset under the action of the torsion spring 45, that is, the swing arm 41 is firstly switched from the released state to the to-be-retracted state, and then is switched from the to-be-retracted state to the retracted state.

When the swing arm 41 moves toward the swing gap 50, the second abutment surface 432 on the swing arm 41 abuts against the first abutment surface 24 on the rotation stop block 20, i.e., the swing arm 41 pushes the rotation stop block 20 and the moving block 32 to move upward. The elastic hook 36 is abutted against the first guide inclined plane 331 of the second limiting step 327, the elastic hook 36 deforms towards one side of the switching channel 60 under the guiding action of the first guide inclined plane 331, when the elastic hook 36 moves to the horizontal gap between the second limiting step 327 and the guide limiting block 328, the elastic hook 36 resets and swings under the action of elastic potential energy, namely the elastic hook 36 swings between the second limiting step 327 and the guide limiting block 328, the elastic hook 36 can be clamped with the second clamping inclined plane 332, and the moving block 32 drives the rotation stopping block 20 to shrink, so that the rotation stopping block 20 is switched to an unlocking state.

In a second aspect, embodiments of the present application disclose a balanced scooter.

Referring to fig. 16, the balance scooter includes a frame 80, and wheels 90 are rotatably connected to the frame 80 at intermediate positions in the longitudinal direction, and in this embodiment, two wheels 90 are preferably provided. The frame 80 is provided with two pedals 81, the two pedals 81 are symmetrically arranged about the axis of the wheel 90, and the auxiliary loading device in the previous embodiment is installed below one of the pedals 81, and plays a role of auxiliary support when the vehicle is loaded.

Referring to fig. 17, when the auxiliary boarding device is not used, an included angle α is formed between the horizontal plane of the frame 80 and the supporting plane, and the user needs to maintain the frame 80 in a relatively horizontal state by completely relying on the self-balancing force.

Referring to fig. 18, the swing arm 41 in the auxiliary boarding device is opened to increase the distance between one of the pedals 81 and the ground when the horizontal plane of the frame 80 forms an angle beta with the supporting plane. Because contained angle beta is far less than the deflection angle of contained angle alpha, in the boarding process, balanced scooter adjusts the angle of horizontal state wobbling from the inclination state and diminishes, can reduce the degree of difficulty of boarding.

It should be noted that, since the overall center of gravity of the user is still on the balance scooter when getting off, the swing arm 41 automatically retracts after the balance scooter is balanced, and the difficulty of getting off the user is not affected. Instead, the retraction of the swing arm 41 can avoid collision between the swing arm 41 and the protrusion on the supporting plane such as the ground during the running process, so as to ensure the stability during the running process.

In a third aspect, the embodiments of the present application further disclose an auxiliary method for a balanced scooter, where the balanced scooter in the above embodiment is used for assisting a driver, and of course, the balanced scooter may be other similar drivers.

The auxiliary method of the balance scooter comprises the following steps:

referring to fig. 19, the swing arm 41 in the auxiliary mechanism 40 is rotated, and the swing arm 41 may be rotated electrically or manually to bring the swing arm 41 into a released state for bringing the auxiliary member 42 into contact with the support plane. That is, after the auxiliary member 42 contacts with the supporting plane, the distance between one side of the balance scooter and the ground is large, and the inclination angle of the balance scooter is small.

Referring to fig. 20, a first pressure F1 is applied to one side of the frame 80, and the first pressure F1 is applied to the swing arm 41 and the auxiliary member 42, and at this time, the user gets on the vehicle from the frame 80 on the side where the auxiliary getting-on device is installed, the first pressure F1 is the weight force applied to the frame 80 by the user. The swing arm 41 and the auxiliary member 42 are deflected by the first pressure F1 toward the swing gap 50, the swing arm 41 is switched from the released state to the retracted state, and the rotation stop block 20 is switched to the unlocked state in synchronization.

Referring to fig. 21, a second pressure F2 is applied to the other side of the frame 80, i.e., the side on which the auxiliary loading device is not mounted, of the frame 80.

The first pressure F1 is separated from the swing arm 41 and the auxiliary piece 42, and a user transfers part of gravity to the other side of the frame 80, namely, the first pressure F1 does not act on the swing arm 41 and the auxiliary piece 42, and the balance scooter can keep balance by deflecting a small angle. At this time, the swing arm 41 and the auxiliary member 42 automatically rotate and reset, so that the swing arm 41 is switched from the released state to the contracted state. The swing arm 41 and the auxiliary piece 42 can be prevented from colliding with the protrusions on the supporting plane such as the ground, and stable running of the balance scooter is ensured.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
