[0047] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0048] Please also read Figures 1 to 8 Now, the automatic folding scooter provided in the embodiment of the present application is described. The automatic folding scooter comprises: a frame 10 , a front wheel assembly 11 and a rear wheel assembly 12 .

[0049] The front wheel assembly 11 and the rear wheel assembly 12 are both mounted on the frame, and the frame is also mounted with a seat folding mechanism 13, a seat 14, a backrest 15 and a first automatic actuator 16; the seat folding mechanism 13 includes a first connecting rod 131 and a second connecting rod 132, one end of the first connecting rod 131 and the second connecting rod 132 can be rotatably mounted on the frame 10; a base frame 141 is provided at the bottom of the seat 14, a locking assembly is provided at the rear side of the base frame 141, and the other ends of the first connecting rod 131 and the second connecting rod 132 are pivotally connected to the base frame 141; a first movable shaft 142 is movably mounted on the base frame 141, and a third connecting rod 143 is pivotally connected to the end of the first movable shaft 142, and the other end of the third connecting rod 143 is pivotally connected to the end of the third connecting rod 143. The first end of the backrest 15 is pivoted to the second connecting rod 132; the backrest 15 can be rotatably installed on the rear side of the seat 14, the backrest 15 is pivoted to the fourth connecting rod 151, and the other end of the fourth connecting rod 151 is pivoted to the first connecting rod 131; the first automatic actuator 16 has a first telescopic rod 161, the first automatic actuator 16 is installed on the first movable shaft 142, and the first telescopic rod 161 is pivoted to the locking assembly; when the first telescopic rod 161 is telescoped, it can drive the first movable shaft 142 to link the third connecting rod 143 to act on the first connecting rod 131 and the second connecting rod 132 to swing the folding seat 14 forward and downward, and at the same time link the fourth connecting rod 151 to act on the backrest 15 to swing backward and downward to fold.

[0050] Specifically, a first movable shaft 142 movably mounted on a base frame 141 is provided, and a locking assembly is provided on the rear side of the frame; a first automatic actuator 16 is installed on the first movable shaft 142, and a first telescopic rod of the automatic self-propelled device is pivotally connected to the locking assembly; when automatic folding is performed, the first telescopic rod can be driven by the first automatic actuator 16 to link the first connecting rod 131, the second connecting rod 132, the third connecting rod 143 and the fourth connecting rod 151 to rotate to complete the automatic folding or unfolding of the seat 14 and the backrest; when manual folding is performed, the connection between the first telescopic rod and the base frame 141 is separated by the locking assembly, and when the seat 14 and the backrest are manually folded or unfolded, the first automatic actuator 16 will not be pulled, which is beneficial to reduce the force of the user when performing manual folding or unfolding, achieving the effect of saving time and effort, thereby improving the convenience of manual folding or unfolding for the user.

[0051] In some embodiments of the present application, the locking assembly includes a locking base 144 and a locking member 146. The locking base 144 is fixedly installed on the rear bottom of the base frame 141. The locking base 144 is installed with a movable member 145 that can move up and down, and a first locking notch 1451 is provided at the bottom of the movable member 145; one end of the locking member 146 is pivotally connected to the first telescopic rod 161, and the other end is provided with a first locking shaft 147 that can be buckled into the first locking notch 1451.

[0052] Specifically, when automatic folding is performed, the locking piece 146 is moved downward, so that the first locking shaft 147 can be buckled into the first locking notch 1451; thereby completing the connection between the first automatic actuator 16 and the base frame 141; when the first telescopic rod of the first automatic actuator 16 is retracted, it can drive the first movable shaft 142 to move from front to back, thereby linking the third connecting rod 143 to cause the first connecting rod 131 and the second connecting rod 132 to swing the folding seat 14 forward and downward, and at the same time linking the fourth connecting rod 151 to cause the backrest 15 to swing backward and downward to fold.

[0053] It can be understood that when the first telescopic rod of the first automatic actuator 16 is extended, it can drive the first movable shaft 142 to move from the back to the front, thereby linking the third connecting rod 143 to cause the first connecting rod 131 and the second connecting rod 132 to swing upward and backward to unfold the seat 14, and at the same time linking the fourth connecting rod 151 to cause the backrest to swing forward and upward to stand upright on the rear side of the seat 14.

[0054] To be more specific, when the user needs to perform manual folding, the user first moves the locking member 146 upward to allow the first locking shaft 147 to exit the first locking notch 1451, thereby disconnecting the first telescopic rod from the base frame 141; then the backrest 15 is directly pushed backward and downward, while the first connecting rod 131 and the second connecting rod 132 are linked to swing forward and downward through the fourth connecting rod 151 to complete the folding of the backrest 15 and the seat 14; when manual unfolding is required, the backrest 15 is directly pushed upward and forward to swing, and the first connecting rod 131 and the second connecting rod 132 can be linked to swing upward and backward through the fourth connecting rod 151 to unfold the seat 14 and the backrest.

[0055] In other embodiments of the present application, the front side of the base frame 141 is provided with a second lock 148 pivotally connected, and the second lock 148 is provided with a second lock notch 149; when the second lock 148 rotates relative to the base frame 141, the second lock notch 149 can be buckled into the end of the first movable shaft 142. When manually folding, the second lock 148 is buckled into the first movable shaft 142, and then a force is applied to the seat 14 or the backrest, so that the movement of the first movable shaft 142 can be linked to the fourth connecting rod 151, the first connecting rod 131 and the second connecting rod 132 to swing forward and downward to complete the folding of the backrest 15 and the seat 14. In other words, the second lock 148 is buckled into the end of the first movable shaft 142 when manually folding; when electrically folding, the second lock 148 needs to be rotated to disengage the end of the first movable shaft 142; at the same time, the lock member 146 needs to be moved upward to exit the buckling connection with the first movable shaft 142.

[0056] Specifically, the left and right sides of the bottom of the base frame 141 are both provided with first limiting notches 1411 , and the left and right ends of the first movable shaft 142 are movably installed corresponding to the two first limiting notches 1411 .

[0057] It should be noted that a first link 131 and a second link 132 constitute a set of link mechanisms, and there are two sets of link mechanisms in total, which are respectively installed on the left and right sides of the top of the frame 10; the corresponding third link 143 and the fourth link 151 are adapted to the quantity setting of each set of link mechanisms.

[0058] In more detail, the top of the first connecting rod 131 is provided with a first pivoting position 1311 and a second pivoting position 1312, the first pivoting position 1311 and the second pivoting position 1312 are arranged at intervals in front and back, and the second pivoting position 1312 is higher than the first pivoting position 1311; the base frame 141 is pivoted with the first pivoting position 1311 of the first connecting rod 131, and the fourth connecting rod 151 is pivoted with the second pivoting position 1312. The top of the second connecting rod 132 is provided with a third pivoting position 1321 and a fourth pivoting position 1322, the third pivoting position 1321 and the fourth pivoting position 1322 are arranged at intervals in the upper and lower directions; the base frame 141 is pivoted with the third pivoting position 1321, and the fourth connecting rod 151 is pivoted with the fourth pivoting position 1322.

[0059] It should be noted here that the pivoting method of the first connecting rod 131, the second connecting rod 132, the third connecting rod 143 and the fourth connecting rod 151 are all pivoted together using a shaft and a hole structure. The method of pivoting together using a shaft and a hole structure is a common means used by technical personnel in this field and will not be elaborated here.

[0060] In other embodiments of the present application, the front wheel assembly 11 includes a steering seat 111, a steering link 114 and a front wheel; the steering seat 111 can be rotatably mounted on the frame 10; the steering seat 111 is pivotally connected to a steering rod 112 and a second automatic actuator 113, and the second automatic actuator 113 can drive the steering rod 112 to rotate relative to the steering seat 111 to fold down or stand up; the steering link 114 is installed at the bottom of the frame 10, and the steering seat 111 can drive the steering link 114 when it rotates; the front wheels 115 are respectively installed at both ends of the steering link 114 and are located on both sides of the front end of the frame 10.

[0061] Specifically, it also includes a locking assembly 116, which includes a first base 1161, a first locking shaft 1162 and a first locking member 1163; the first base 1161 is fixedly mounted on the steering rod 112, the first locking shaft 1162 is fixedly mounted on the output end of the second automatic actuator 113; the first locking member 1163 is movably mounted on the first base 1161; the rear side of the first locking member 1163 is provided with a first locking recess 1164 for inserting the first locking shaft 1162. Preferably, the first automatic actuator 116 and the second automatic actuator 113 can use an automatic cylinder or an automatic oil cylinder to realize automatic folding or automatic unfolding of the steering rod 112, so the second automatic actuator 113 has a second telescopic rod, and the first locking shaft 1162 is arranged on the second telescopic rod.

[0062] A spring is provided between the first locking member 1163 and the first base 1161, and the spring is used to provide an elastic force for the first locking member 1163 to move backward. When the first locking member 1163 is automatically folded, the first locking shaft 1162 is buckled into the first locking recess 1164, and the second telescopic rod is extended and retracted to push the steering rod 112 to swing upward and forward to stand upright, or to push the steering rod 112 to swing downward and backward to fold. When manual folding is required, the first locking member 1163 is pulled forward to disengage the first locking shaft 1162 from the first locking recess 1164, and the steering rod 112 is pushed upward and forward to stand upright, or to push the steering rod 112 to swing downward and backward to fold. It can be seen that when manual folding is performed, the connection between the second automatic actuator 113 and the steering rod 112 can be separated by the locking assembly 116, and the second automatic actuator 113 will not be pulled, thereby achieving the effect of saving time and effort, reducing the force of the user during manual folding, and improving the user's convenience.

[0063] It is understandable that the locking assembly 116 structure can also be applied to the locking connection between the first automatic actuator 16 and the base frame 141 .

[0064] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementation methods of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
