As shown in fig. 2 and 3, in one embodiment, the pull rod 4 is a telescopic rod which is pressed to switch to a contracted position when the foldable vehicle body 1 is in the first use state, and which is stretched to switch to an extended position suitable for the height of the user when the foldable vehicle body 1 is in the second use state. Therefore, the adaptability function of the pull rod 4 in different use states is improved through flexible switching of the pull rod 4 between two positions, the operation and use of a user are more convenient, and the portability of the pull rod is further improved. Obviously, the telescopic rod for the vehicle body frame can be an existing drawing fixed rod body structure, and is not described in detail herein.

Wherein, be equipped with the mounting bracket on the foldable automobile body 1, mounting bracket and knapsack body 2 looks adaptation. Specifically, the mounting bracket at least contains bracket 9 that is used for knapsack body 2 bottom and connecting seat 10 that is used for knapsack body 2 back, and all is equipped with magnetism on bracket 9 and the connecting seat 10 and inhales the piece (not shown), and the mutual magnetism of piece and knapsack body 2 is inhaled with magnetism and is docked. Its automobile body adopts the magnetism mode of inhaling to have good absorption fixed effect through mounting bracket and knapsack, has more portable removable function.

Wherein, the connecting seat 10 is laterally sleeved on the lower body of the telescopic rod and can be movably adjusted relative to the lower body, and the bracket 9 is extended and arranged at the front end side of the front wheel set 6 where the folding type vehicle body 1 is positioned. Thereby ensure no matter when arbitrary user state, connecting seat 10 and bracket 9 homoenergetic cooperate to realize inhaling spacingly to the quick magnetism of knapsack body 2, and make things convenient for the dismouting to use.

As shown in fig. 3 and 4, in one embodiment, the foldable vehicle body 1 extends horizontally and upwardly bent at the rear end side of the rear wheel set 7 to form a snap plate 11, and the snap plate 11 allows the handle of the pull rod 4 switched to the retracted position to be butt-fixed in the panel. Wherein, the handle 3 forms a cross handle support at the top of the pull rod 4, and the clamping plate 11 arranged in a bending way can be just clamped on the pull rod 4 after the pull rod 4 is pressed and switched to the contraction position, so as to form a fixed position to ensure further storage and portable operation and use.

In one embodiment, the front portion of the slider member 5 is hingedly engaged with the end portion of the pull rod 4 by a ball joint structure 12, so that the pull rod 4 is rotatably engaged with the slider member 5 in a plurality of directions. Therefore, through the connection mode of the spherical hinge head, the flexibility of the pull rod 4 on the sliding plate piece 5 is higher, the steering operation of the pull rod in the second use state is supported, the left and right turning angles can be maximally reached, and the use requirements of crossing lanes on the street are met.

As shown in fig. 2, 3 and 6, the shoulder strap 8 is elastically attached to and accommodated in the bottom end surface of the sliding plate 5 in the initial state, and the shoulder strap 8 is made of a nano fabric material, thereby improving the waterproof and antifouling functions thereof. Wherein, the folding vehicle body 1 is made of aviation aluminum carbon fiber. It can be understood that the shoulder strap 8 is attached to the bottom end of the skateboard part 5 when not in use, so that the problems of interference and abrasion when the scooter is driven and used are avoided, and the shoulder strap is made of a material which is more beneficial to the user to bear the scooter.

In one embodiment, a battery module (not shown) is disposed in the sled member 5, and the handle 3 is configured to rotatably control the operating handle for rotating the front wheel set 6 and/or the rear wheel set 7 thereof in the second use state. It can be understood that in the second use state, the motor of the operating handle control skateboard part 5 drives any wheel set to rotate, so as to drive the scooter in an electric mode. In other embodiments, the scooter can be driven manually by directly pedaling the scooter by the user, which is enough to satisfy the walking requirement of the user.

The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention.
