Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Example 1:

the embodiment provides a specific structure of a folding mechanism for a scooter, which comprises a fixed seat 1, wherein a rotating groove member 2 is arranged at the top of the fixed seat 1, a limiting groove member 3 is arranged in the rotating groove member 2, a rotating rod 4 is rotatably connected in the limiting groove member 3 through a rotating shaft 6, a handle 5 is inserted in the rotating rod 4, and the handle 5 is rotatably connected with the side wall of the rotating rod 4;

handle 5 lower extreme rotates and is connected with connecting rod 7, and connecting rod 7 lower extreme both sides all are provided with fastener 8, and fastener 8 slides and passes 4 lateral walls of bull stick, and reset slot 10 and folding slot 11 have all been seted up at spacing groove 3 both ends.

Further, be provided with spring 9 on fastener 8, fastener 8 links to each other with pivot 8 through spring 9, rotates handle 5 and drives connecting rod 7 and move up, and then drives fastener 8 and shift up, and spring 9 is in tensile state this moment, and when fastener 8 card goes into to reset draw-in groove 10 or folding draw-in groove 11, spring 9 resets, provides an effort for handle 5, prevents that the mistake from bumping handle 5 and leading to fastener 8 from resetting draw-in groove 10 or folding draw-in groove 11 roll-off, has improved the holistic stability of folding mechanism.

Further, the handle 5 is arranged on the front surface of the rotating rod 4, the handle 5 is of an L-shaped structure, the horizontal section of the handle is rotatably connected with the rotating rod 4, and the tail end of the horizontal section of the handle is rotatably provided with a connecting rod 7.

Further, two fasteners 8 are symmetrically arranged on the left side and the right side of the connecting rod 7 respectively, the limiting groove member 3 is of a U-shaped structure, the left side wall and the right side wall of the limiting groove member are of a semicircular structure, two reset clamping grooves 10 are symmetrically arranged at the rear ends of the left side wall and the right side wall of the limiting groove member 3 respectively, and two folding clamping grooves 11 are symmetrically arranged at the front ends of the left side wall and the right side wall of the limiting groove member 3 respectively.

In the folding/resetting process, the clamping piece 8 takes the rotating shaft 6 as a circle center, circular motion is carried out at the tops of the left side wall and the right side wall of the limiting groove piece 3, the left side wall and the right side wall of the rotating groove piece 2 can fix the position of the limiting groove piece 3, the front side wall and the rear side wall of the rotating groove piece can also fix the position of the limiting groove piece 3, the rotating rod 4 can be limited, and the rotating rod 4 can be controlled to rotate at the maximum angle.

Furthermore, when the folding state is achieved, the two clamping pieces 8 are respectively clamped in the corresponding folding clamping grooves 11.

Furthermore, in the reset state, the two clamping pieces 8 are respectively clamped in the corresponding reset clamping grooves 10.

According to the working principle, referring to fig. 1-3, when the folding mechanism is folded, the vertical section of the handle 5 is rotated downwards, the tail end of the horizontal section of the handle 5 is rotated upwards, so that the connecting rod 7 is pulled to move upwards, the clamping piece 8 is driven to slide upwards until the clamping piece 8 slides out of the reset clamping groove 10, the spring 9 is stretched, the rotating rod 4 is rotated, the clamping piece 8 circularly moves at the tops of the left side wall and the right side wall of the limiting groove piece 3 by taking the rotating shaft 6 as the center of a circle until the clamping piece reaches the upper part of the folding clamping groove 11, the clamping piece 8 slides into the folding clamping groove 11 under the action of the elastic force of the spring 9, and the folding mechanism is folded;

when folding mechanism expandes (resets), 5 vertical sections of downward rotation handle, 5 horizontal segment ends of handle upwards rotate, thereby pulling connecting rod 7 upward movement, and then drive fastener 8 upwards and slide, until 8 roll-off folding slot 11 of fastener, spring 9 is tensile this moment, rotate bull stick 4, fastener 8 uses pivot 6 as the centre of a circle this moment, circular motion is made at 3 left and right sides wall tops of spacing groove spare, until reaching the top of resetting slot 10, fastener 8 slides into in the resetting slot 10 under the effect of spring 9 elasticity, folding mechanism is folding to be accomplished.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
