Abstract

The invention discloses a foldable bicycle handlebar. The patent of the invention has two states: an unfolded state and a folded state. The folding bicycle is unfolded during normal use of the bicycle and folded during storage of the bicycle. Consists of two handlebar cross rod groups and one handlebar vertical rod group. The handlebar cross-bar set is provided with a locking sleeve to ensure the structural stability of the handlebar cross-bar set in two states. The handlebar cross rod group is fixedly connected with a handlebar rotating shaft in the handlebar vertical rod group through a handlebar fixing pin. When the bicycle is in non-state conversion, the locking sleeve ensures that the relative position between the handlebar cross rod group and the vertical rod group is locked. Two semicircular grooves are arranged on the locking sleeve, and when the locking sleeve is in an unfolded state and a folded state respectively, a certain pulling force is generated through the reset spring, so that the locking sleeve and the upright rod group are mutually clamped. The locking of the positions of the handlebar cross rod group and the vertical rod group can be released by adjusting the position of the locking sleeve, and the folding handlebar is converted into a folding state by rotating the handlebar cross rod group.

Description

Foldable bicycle handlebar

Technical Field

The invention relates to the technical field of bicycles, in particular to a foldable bicycle handlebar.

Background

As the existing tools for riding instead of walk in China with the largest quantity, bicycles play an important role in the life of people. The invention relates to a foldable bicycle, which aims to enable the storage of the bicycle to be more ergodic. However, most prior art bicycle folding solutions do not have a foldable design for the handlebar portion. To address this problem, utility model patent CN201320797376.0 discloses a bicycle handlebar that can be folded to one side. The invention patent CN201510044596.X discloses a bicycle folding handlebar, and provides a kun-bike handlebar capable of adjusting the distance between handlebars and folding. The technical scheme of the folding of the handlebar has further researched space.

Disclosure of Invention

The invention aims to provide a foldable bicycle handlebar, which is characterized in that a rotation axis and a handlebar axis form an included angle of 45 degrees in the folding process of the handlebar, and the rotation in the direction of the inclined axis changes the spatial posture of the handlebar and enables the axis to be parallel to the handlebar axis. And a locking sleeve containing a return spring is arranged on the handlebar, and the unfolding and folding states of the handlebar can be locked through the design of the sleeve and the handle structure.

The invention discloses a foldable bicycle handlebar, which has two states: an unfolded state and a folded state. The folding bicycle is unfolded during normal use of the bicycle and folded during storage of the bicycle.

The technical scheme adopted by the invention is as follows: the invention is composed of two handlebar cross rod groups and one handlebar vertical rod group. The handlebar cross-bar set is provided with a locking sleeve to ensure the structural stability of the handlebar cross-bar set in two states. The main body of the handlebar vertical rod group is a T-shaped rod, a handlebar rotating shaft is arranged on the handlebar vertical rod group, and an included angle of 45 degrees is formed between the rotating axis direction of the handlebar rotating shaft and the main axis direction of the T-shaped rod. The handlebar cross rod group is fixedly connected with a handlebar rotating shaft in the handlebar vertical rod group through a handlebar fixing pin.

When the bicycle is in non-state conversion, the locking sleeve ensures that the relative position between the handlebar cross rod group and the vertical rod group is locked. Two semicircular grooves are arranged on the locking sleeve, and when the locking sleeve is in an unfolded state and a folded state respectively, a certain pulling force is generated through the reset spring, so that the locking sleeve and the upright rod group are mutually clamped. The locking of the positions of the handlebar cross rod group and the vertical rod group can be released by adjusting the position of the locking sleeve, and the folding handlebar is converted into a folding state by rotating the handlebar cross rod group.

Compared with the prior art, the folding device not only enables the axis to be adjusted from the horizontal state to the vertical state (when the vertical axis is vertical to the ground) in the folding process, but also enables the axis to be inverted by 180 degrees along the rotation axis. After the handlebar is folded, the brake and other structures generally arranged on the front side of the handlebar can be folded to the rear side of the handlebar, and the interference between the structures and other structures when the structures are stored can be avoided after the handlebar is folded.

Detailed Description

The present invention will be further described with reference to the following examples, but the present invention is not limited to the following examples.

Example 1

As shown in fig. 1 and 2, the present invention has two states: an unfolded state and a folded state. The folding bicycle is unfolded during normal use of the bicycle and folded during storage of the bicycle.

As shown in FIG. 3, the present invention is composed of two handlebar cross bar sets 1 and one handlebar stem set 2. The handlebar cross rod group 1 is connected with the handlebar upright rod group 2 through a handlebar fixing pin 3.

As shown in fig. 4, the handlebar stem set 1 is composed of a spring fixing pin 6, a locking sleeve 7, a return spring 8, a sleeve fixing pin 9, and a handlebar body 12. The inside design of handlebar body 12 has logical groove, and reset spring 8 places in the logical inslot of handlebar body 12, and handlebar body 12 is fixed through the one end of spring fixed pin 6 with reset spring 8. The locking sleeve 7 is fitted over the handlebar body 12, and the locking sleeve 7 is fixed to one end of the return spring 8 by a sleeve fixing pin 9. The length of the return spring 8 can be changed by pulling the locking sleeve 7, and the return spring 8 can return the locking sleeve 7 to the locking position when no external force is applied.

As shown in fig. 4, the stem set 2 is composed of a handle bar rotating shaft 4, a rotating shaft end cover 5, a sliding bearing 10 and a T-shaped stem 11. The inner hole of the rotating shaft end cover 5 is fixedly connected with the outer ring of the sliding bearing 10, and the inner hole of the sliding bearing 10 is fixedly connected with the handlebar rotating shaft 4. The T-shaped rod 11 and the rotating shaft end cover 5 are fixed through screws. The handlebar rotating shaft 4 can rotate relative to the T-shaped rod 11, and the rotating axis direction of the handlebar rotating shaft 4 and the main axis direction of the T-shaped rod 11 form an included angle of 45 degrees.

When the bicycle is not in a state transition, the locking sleeve 7 ensures that the relative position between the handlebar cross rod group 1 and the vertical rod group 2 is locked. Two semicircular grooves are formed in the locking sleeve 7, and when the locking sleeve is in an unfolded state and a folded state respectively, a certain pulling force is generated through the reset spring 8, so that the locking sleeve and the upright rod group 2 are mutually clamped. The locking of the positions of the handlebar cross rod group 1 and the upright rod group 2 can be released by adjusting the position of the locking sleeve 7, and the folding handlebar is converted into a folding state by rotating the handlebar cross rod group 1.

The above examples are provided for clarity of illustration only and are not intended to limit the invention to the particular embodiments described. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
