AI Technical Summary
The handlebars of existing scooters are not compact enough when folded, and the traditional plug-in locking mechanism is cumbersome to operate and prone to wear and failure, posing a safety hazard of accidental folding.
A locking mechanism is adopted, including a first locking member and a second locking member. The handle is restricted to its unfolded state through a four-bar linkage structure. The mechanical self-locking is achieved by utilizing the driving force naturally generated by the handle gripping force, thus preventing the risk of accidental folding.
It effectively avoids the risk of accidental folding, improves structural compactness and operational safety, simplifies the operation process, and overcomes the shortcomings of traditional locking mechanisms.

Abstract
Claims
1. A carrier comprising a frame and a handle, the handle being pivotally connected to the frame by a first pivot such that the handle has an unfolded state and a folded state; characterized in that, The vehicle also includes: A locking mechanism configured to keep the handle in the extended position; The locking mechanism includes: A first locking member, which is pivotally connected to the handle via a second pivot; and The second locking member is pivotally connected to the first locking member via a third pivot and to the vehicle frame via a fourth pivot; Wherein, the axes of the first pivot, the second pivot, the third pivot, and the fourth pivot are parallel and not collinear; the axis of the second pivot and the axis of the third pivot together define a first imaginary plane; and the axis of the third pivot and the axis of the fourth pivot together define a second imaginary plane. When the handle is in the unfolded state, the movement of the third pivot in the direction of the first pivot is constrained, and the angle between the side of the first imaginary plane facing the first pivot and the side of the second imaginary plane facing the first pivot is at least 180 degrees, so as to restrict the handle from switching from the unfolded state to the folded state.
2. The vehicle of claim 1, wherein, When the handle is in the extended state, the first locking member and / or the second locking member abut against the handle to restrain the movement of the third pivot in the direction of the first pivot; or When the handle is in the extended state, the first locking member and / or the second locking member abut against the frame to restrain the movement of the third pivot in the direction of the first pivot.
3. A carrier according to claim 2, wherein, The first locking member has an abutment portion, and the handle has a groove that mates with the abutment portion.
4. The vehicle of claim 1, wherein, When the handle is in the extended state, the first pivot is vertically higher than the first imaginary plane and the second imaginary plane.
5. The vehicle of claim 1, wherein, When the handle is in the extended state, the angle between the side of the first imaginary plane facing the first pivot and the side of the second imaginary plane facing the first pivot is 180 degrees to 250 degrees, and the axis of the second pivot and the axis of the fourth pivot together define the third imaginary plane. Along a direction perpendicular to the third imaginary plane, the projection of the first pivot falls into the middle position of the third imaginary plane.
6. A carrier according to any one of claims 1 to 5, wherein, The shortest distance between the axis of the first pivot and the axis of the second pivot is L1, the shortest distance between the axis of the second pivot and the axis of the third pivot is L2, the shortest distance between the axis of the third pivot and the axis of the fourth pivot is L3, and the shortest distance between the axis of the fourth pivot and the axis of the first pivot is L4, and satisfies: L1:L2=1:(0.7-1.3), L1:L3=1:(0.7-1.3), L1:L4=1:(0.7-1.3).
7. The vehicle of claim 1, wherein When the handle switches from the unfolded state to the folded state, the handle rotates 70 to 110 degrees around the axis of the first pivot.
8. A carrier according to claim 1 or 7, wherein When the handle is in the unfolded state, the side of the first imaginary plane facing the first pivot is the first side, and the side of the second imaginary plane facing the first pivot is the second side. When the handle is folded, the angle between one side of the first imaginary plane and the second side of the second imaginary plane is at least 60 degrees.
9. The vehicle of claim 1 or 2, wherein, The vehicle also includes: A retaining member configured to keep the handle in a folded state; The retaining member is a damping member and / or a magnetic member; The retaining member is arranged at at least one of the following positions: Between the handle and the frame; Between the handle and the first locking member; Between the first locking member and the second locking member; and Between the second locking member and the frame.
10. The vehicle of claim 1, wherein, The frame comprises: A pedal; and A vertical rod arranged on the pedal; The number of the handles is two, and the two handles are respectively arranged on two sides of the vertical rod and are both pivotally connected to the vertical rod through the first pivot; The second locking member in the locking mechanism is pivotally connected to the vertical rod.
