[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention. All other embodiments obtained by ordinary technicians in the field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.

[0035] Embodiment 1

[0036] The present invention provides a folding device for an electric scooter, see Figure 1-13 The folder includes an upper bowl 1 and a lower bowl 2 which are rotatably connected. The upper bowl 1 is used to be connected to the vertical pole 3 of the electric scooter, and the lower bowl 2 is used to be connected to the head pipe 4 of the electric scooter. A limiting mechanism is provided between the upper bowl 1 and the lower bowl 2. The limiting mechanism includes a folding handle 51. One end of the folding handle 51 is rotatably connected to the lower bowl 2. The folding handle 51 is provided with a first limiting groove 52. The upper bowl 1 is provided with a first limiting member 53 which can cooperate with the first limiting groove 52. The first limiting member 53 and the first limiting groove 52 are used to limit the vertical pole 3 from swinging up and down.

[0037] The upper bowl 1 of the folder is used to connect with the upright pole 3, and the lower bowl 2 of the folder is used to connect with the head tube 4. The upper bowl 1 of the folder can rotate eccentrically relative to the lower bowl 2 of the folder, so that the upright pole 3 and other accessories connected to the upright pole 3 can be driven to rotate through the upper bowl 1 of the folder, thereby realizing the folding of the electric scooter. It should be noted that the upper bowl 1 of the folder and the lower bowl 2 of the folder are both hollow structures, and the hollow cavities of the upper bowl 1 of the folder and the lower bowl 2 of the folder are used for routing the electronic accessories of the electric scooter.

[0038] A limiting mechanism is provided between the upper bowl 1 of the folder and the lower bowl 2 of the folder, and the limiting mechanism is used to limit the vertical rod 3 and other accessories connected thereto from swinging up and down after being folded. Specifically, the limiting mechanism includes a first limiting member 53 and a first limiting groove 52, and the first limiting groove 52 is located on the folding handle 51. When an external force is applied to the vertical rod 3, the upper bowl 1 of the folder is driven to rotate, and the folding handle 51 is driven to rotate at the same time. After the folding handle 51 rotates to a preset angle, the first limiting groove 52 provided thereon will form a clamping fit with the first limiting member 53 on the upper bowl 1 of the folder, thereby limiting the vertical rod 3 and other accessories connected thereto from swinging in the up and down directions. Preferably, the first limiting member 53 proposed in this embodiment is a limiting screw, which is only exemplary and not restrictive, and those skilled in the art can set it according to actual conditions.

[0039] Embodiment 2

[0040] The limiting mechanism proposed in the embodiment of the present invention also includes a second limiting member 54 which is penetrated on the lower bowl 2. The second limiting member 54 is located at the side where the folding handle 51 is rotatably connected to the lower bowl 2. A first elastic member 55 is sleeved on the second limiting member 54. The upper end of the second limiting member 54 is exposed below the folding handle 51. A second limiting groove is provided on the head tube 4 corresponding to the second limiting member 54. The second limiting member 54 and the second limiting groove are used to limit the left and right swing of the upright 3. In this embodiment, when the electric scooter is folded, the folding handle 51 will rotate relative to the lower bowl 2 of the folding device. During the rotation of the folding handle 51 relative to the lower bowl 2 of the folding device, the lower end of the folding handle 51 will gradually approach and abut the second limiting member 54 located below it. When the folding handle 51 rotates to a preset angle, the second limiting member 54 will move downward in the vertical direction under the action of the folding handle 51. At this time, the second limiting member 54 will form a clamping fit with the second limiting groove, thereby limiting the swing of the upright 3 and other accessories connected thereto in the left and right directions. Preferably, the second limiter 54 proposed in this embodiment is a limiter pin, which is only exemplary and not restrictive, and can be set by a person skilled in the art according to actual conditions. The main function of the first elastic member 55 is to reset. Specifically, when the second limiter 54 is pressed down, the first elastic member 55 will be compressed to generate an elastic force in an upward direction. After the electric scooter is released from the folded state, the second limiter 54 will move upward under the action of the first elastic member 55 until it is reset to the initial position. Preferably, the first elastic member 55 proposed in this embodiment is a telescopic spring.

[0041] Embodiment 3

[0042] See also Figure 5 The folding device of the electric scooter proposed in the embodiment of the present invention further includes a first fixing plate 56 for fixing the second limiting member 54. The first fixing plate 56 is provided with a first fixing hole for fixing the first fixing plate 56 to the lower bowl 2 and a first through hole for the second limiting member 54 to pass through. A sliding groove for the second limiting member 54 to move up and down is provided below the first through hole. The second limiting member 54 is sleeved with an annular clamping block 57 located below the first fixing plate 56. In this embodiment, a waist-shaped groove for installing the first fixing plate 56 is provided on the lower bowl 2 of the folder. The first fixing plate 56 is fixed to the lower bowl 2 by screws. The second limiting member 54 is arranged in the vertical direction. The second limiting member 54 first passes through the through hole on the first fixing plate 56 and then penetrates into the sliding groove. To prevent the second limiting member 54 from sliding out of the sliding groove, an annular clamping block 57 is sleeved on the second limiting member 54. The annular clamping block 57 is located below the first fixing plate 56. After the second limiting member 54 slides upward a preset distance, the annular clamping block 57 will be clamped at the bottom end of the first fixing plate 56 to limit the second limiting member 54 from continuing to slide upward.

In this embodiment, the second stopper 54 is located at the side where the upper bowl 1 is rotatably connected to the lower bowl 2. When folding, the upper bowl 1 will press down the second stopper 54. In the process of pressing down the second stopper 54, the second elastic member 5A will generate an upward elastic force to reset the second stopper 54 when releasing the folded state. More specifically, when the upper bowl 1 is pressed down, it acts on the end surface of the abutment column 542. The abutment column 542 is threadedly connected to the hollow clamping column 541, and the pin 543 is connected to the hollow clamping column 541. Therefore, the abutment column 542, the hollow clamping column 541 and the pin 543 will move toward the head pipe 4 as a whole under the action of the upper bowl 1. It should be noted that the head tube 4 and the lower bowl 2 are rotationally connected. When folded, the pin 543 may not be inserted into the third limiting groove. In this case, since the pin 543 can slide inside the hollow clamping column 541 and one end of the pin 543 is connected to the third elastic member 544, when the pin 543 is not aligned with the third limiting groove, it will move toward the inside of the hollow clamping column 541 under the force of the end face of the head tube 4. At the same time, the third elastic member 544 generates a downward elastic restoring force. Then, the lower bowl 2 is rotated to allow the pin 543 penetrating the lower bowl 2 to be inserted into the third limiting groove.
