[0028] Specific embodiments of the present application are described in conjunction with the accompanying drawings and the following description to teach those skilled in the art how to make and use the best mode of the present application. In order to teach the principles of the application, some conventional aspects have been simplified or omitted. Those skilled in the art should understand that variations from these embodiments fall within the scope of the present application. Those skilled in the art should understand that the following features can be combined in various ways to form multiple variations of the present application. Terms such as "upper", "lower", "left", "right", "middle" and "one" cited in this application are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the utility model without substantial changes in the technical content. Therefore, the present application is not limited to the following specific embodiments, but is only limited by the claims and their equivalents.

[0029] like Figures 1 to 3As shown, the present embodiment relates to a foldable scooter, characterized in that it comprises: a vehicle assembly 1, a handle assembly 2, a seat assembly 3 and an armrest assembly 4, wherein the handle assembly 2 is connected to the front end of the vehicle assembly 1 through a retractable and folding mechanism 6, and the seat assembly 3 is connected to the rear of the vehicle assembly 1 through a folding mechanism 5; the armrest assembly 4 is foldably connected to both sides of the seat assembly.

[0030] In the embodiment of the present application, the folding mechanism 5 includes a support plate 51, four folding uprights 52 located below the support plate 51, and a fixed lock assembly 53 for controlling the folding of the folding uprights 52. The seat assembly 3 is installed above the support plate 51, and the support plate 51 is connected to the vehicle assembly 1 through the folding uprights 52. The fixed lock assembly 53 is installed at the bottom of the support plate 51. When the fixed lock assembly 53 abuts against the top of the folding uprights 52, the folding uprights 52 cannot be folded. Specifically, the four folding uprights 52 are symmetrically connected to the left and right sides below the support plate 51 in pairs, and the two folding uprights 52 on the same side are equipped with a fixed lock assembly 53. The folding uprights 52 include an upper folding rod 521 and a lower folding rod 522. The top of the upper folding rod 521 is hinged to the bottom of the support plate 51, the bottom of the upper folding rod 521 is hinged to the lower folding rod 522, and the bottom of the lower folding rod 522 is hinged to the vehicle assembly 1.

[0031] In addition, if Figure 4 As shown, the fixed lock assembly 53 includes a lock plate 531, a torsion spring 532, a torsion spring shaft 533 and a control plate 534. The torsion spring shaft 532 is connected to the lower side of the support plate 51. The torsion spring 533 is sleeved on the torsion spring shaft 532 and one end of the torsion spring 533 is connected to the support plate 1. The end of the lock plate 531 is connected to the torsion spring shaft 532. The control plate 534 is located on the side of the lock plate 531 and is used to pull the lock plate 531 and the torsion spring 532 shaft to rotate. In addition, in the The upper part of the upper folding rod 521 is provided with a protrusion 523 in contact with the end of the locking plate 531. When locked, the two ends of the locking plate 531 respectively abut against the protrusions 523 of the two upper folding rods 521 on the same side to prevent the upper folding rod 521 from rotating and folding. When folding, the locking plate 531 is pulled to rotate by the control plate 534, and the two ends of the locking plate 531 leave the protrusion 523, and the upper folding rod 521 and the lower folding rod 522 rotate inwardly through the middle hinge, such as Figure 2 In the direction indicated by the arrow.

[0032] like Figure 5As shown, in the embodiment of the present application, the retractable and folding mechanism 6 includes a telescopic tiller 61, a folding rotating shaft 62 and a connecting shaft 63. The telescopic tiller 61 is located above the folding rotating shaft 62 and its top is connected to the handle assembly 2. The telescopic tiller 61 is inserted into the folding rotating shaft 62 and is slidably connected to the folding rotating shaft 62. A first locking member 64 is provided at the connection between the telescopic tiller 61 and the folding rotating shaft 62 for locking the position of the telescopic tiller 61 in the folding rotating shaft 62. The lower end of the folding rotating shaft 62 is hinged to the connecting shaft 63 and the folding rotating shaft 62 is locked by a second locking member 65 to prevent the folding rotating shaft 62 from flipping down and folding. In the present application, the first locking member 64 and the second locking member 65 are both prior art and will not be described in detail.

[0033] like Figure 2 and Figure 6 As shown, in order to further improve the folding effect, in the embodiment of the present application, the armrest assembly 4 includes an armrest 41 and a connecting rod 42, the armrest 41 is rotatably connected to the connecting rod 42, and the connecting rod 42 is rotatably connected to the support plate 51, so that the armrest 41 and the connecting rod 42 can be folded again. Here, the armrest 41 and the connecting rod 42, as well as the connecting rod 42 and the support plate 51 can be fixed by a tight fitting structure or an external locking structure. Similarly, the seat assembly 3 includes a backrest 31 and a cushion 32, the backrest 61 and the cushion 62 are rotatably connected, and the backrest 31 can be flipped down and folded to overlap with the cushion 62.

[0034] The vehicle-machine assembly 1 includes a frame assembly 11, a power supply assembly 12, a front wheel assembly 13, a rear wheel assembly 14 and a steering assembly 15. The front wheel assembly 13 and the rear wheel assembly 14 are respectively located on the front and rear sides of the frame assembly 11. The power supply assembly 12 is installed on the frame assembly 11 to provide power for the scooter. The handle assembly 2 is connected to the front wheel assembly 12 through the retractable and folding mechanism 6 and the steering assembly 15 in turn to control the steering of the front wheel assembly 13.

[0035] The working principle of the utility model is:

[0036] When the handle assembly 2 is folded, the first locking member 64 is opened, so that the telescopic tiller 61 is retracted downward into the folding rotation axis 62, thereby reducing the overall height of the handle assembly 2. Next, the second locking member 65 is opened, and the folding rotation axis 62 can be flipped backward, so that the handle assembly 2 and the retractable folding mechanism 6 are flipped backward onto the frame assembly 11. When the seat assembly 3 and the armrest assembly 4 are folded, first, the backrest 31 is flipped downward onto the seat cushion 32, and then the armrest 41 and the connecting rod 42 are rotated to fold and retract the space. Finally, the fixed lock assembly 53 is opened, so that the lower end of the upper folding rod 521 and the upper end of the upper folding rod 522 are flipped and folded inward, thereby reducing the height of the entire seat assembly 3. The folded mobility scooter is as follows: Figure 2As shown, its overall height is reduced by two thirds compared with before folding.

[0037] Since it is easy for those skilled in the art to think of it, any modification, equivalent substitution, improvement, etc. made within the concept and principle of the application should be included in the scope of the claims of this application.
