Description

Seesaw fence type automatic telescopic bicycle basket

Technical Field

The invention relates to the field of mechanical electronics, in particular to an automatic telescopic bicycle basket which can be automatically telescopic and changed and is used for a bicycle (or other similar vehicles, and the bicycle can be suitable for other similar vehicles). The bicycle using the system can automatically narrow the width of the bicycle basket during storage, and the bicycle provided with the bicycle basket can conveniently and automatically enter and exit the special bin box of the bicycle, so that the storage efficiency can be greatly improved.

Background

The invention relates to a method for automatically deforming bicycles, which is characterized in that bicycles are compressed and stored in a bin box in order, so that not only can the bicycles be conveniently provided for use, but also all the defects of the common shared bicycle are eliminated, and the blade type bicycle refers to a bicycle which is automatically contracted into a blade type bicycle (except a bicycle basket) by using the method; in the contraction deformation of the bicycle, each bicycle is contracted into a blade shape with a width of about 10 cm, and a general bicycle needs to be provided with a basket, so that the automatic width contraction of the basket with a general width of about 30 cm (the height can be about 10 cm) becomes necessary when the bicycle is stored, and the storage efficiency of the automatically contracted basket (contracted to a width of about 10 cm) can be greatly improved compared with the storage efficiency of the bicycle without contracting the saddle.

Disclosure of Invention

In order to make the travel of the bicycle (the bicycle of the invention also comprises similar vehicles such as an electric power-assisted bicycle, an electric bicycle and the like) more intelligent and convenient, the invention provides the automatic telescopic bicycle basket which can automatically change the width of the basket.

The technical scheme adopted by the invention for solving the technical problems is as follows: the bicycle basket consists of a plurality of L-shaped railings which are encircled into a circle, each L-shaped railing is shaped like a seesaw, and one end of each seesaw is lifted and pulled by a motor to ascend or descend; the other end of the seesaw descends to form an extended bicycle basket, and the bicycle basket is retracted when being lifted, so that the purpose of saving space during storage is achieved; the power for driving the bicycle basket to extend and retract comes from an electric mechanism (generally a motor and the like), and the motor is a direct current speed reducing motor with an encoder.

The implementation principle of the invention is described as follows:

a rechargeable battery is placed in the bicycle, and the power of the electric mechanism is provided by the rechargeable battery. Because the bicycle basket of bicycle is exactly a fence frame, its several sides all need not seal like a wall, and the bicycle basket is not sealed but fence structure promptly, and a bicycle basket just has a plurality of crossbands and vertical retort to interweave and forms, leaves a lot of seam, and this fence structure characteristics provide convenience for the flexible of bicycle basket, further simplify, remove some unnecessary crossbands, discover the shrink of the bottom surface strip pole of bicycle basket can adopt the mode of the unequal seesaw of left and right sides to contract and extend: the outer end of the seesaw is vertical to a vertical bar, and the vertical bars can form a circle to form a container for loading articles, namely a bicycle basket when the seesaw basically swings. Because each seesaw is firm enough and can only go up and down without left and right shaking, the vertical bars which form the bicycle basket can be connected without the cross bars to ensure enough strength.

The lifting of one side of the seesaw, namely the short arm, is automatic, power is required to automatically contract in order to realize automation, a middle shaft support fulcrum of the seesaw is fixed on a circle of top seat, a motor is fixed on a base at the lower part of the top seat, the motor drives a push plate to lift up and down, a wire (a steel wire or a hinge and the like) arranged on the push plate can pull the short arm of the seesaw to descend, the end of the short arm of the seesaw is circular, and the short arm of the seesaw can be pushed to ascend and be pressed when the push plate ascends.

When the bicycle basket needs to be retracted during storage, each seesaw in the fence is changed into a vertical direction (basically vertical, the seesaw is prevented from being blocked and cannot lift, the same is used below), the horizontal space occupied by each seesaw is naturally reduced, the height of the bicycle basket is generally not high, more than 10 cm is enough, the angle between the vertical edge strips on the seesaws and the seesaws is larger than 90 degrees, and the horizontal space occupied by the vertical folded seesaw strips is not wide; when the folding type bicycle is used and needs to be extended, each seesaw in the fence is changed into the horizontal direction (basically horizontal, the height of the bicycle basket can be increased by increasing the inclination of the seesaw at the same time), the horizontal space occupied by each seesaw is naturally enlarged, and the enlarged bicycle basket space surrounded by the seesaws and the side bars on the seesaws can contain articles.

One end of the seesaw is pushed and pulled by a motor to ascend or descend: the specific principle is that a motor drives a push plate, the push plate is flexibly connected with one end of a seesaw (a steel wire, a ring, a hinge and the like, the purpose of the flexible connection is to enable the push plate to pull the end of the seesaw to descend together when descending), and the push plate pushes one end of the seesaw to move upwards (when the push plate is arranged at the lower part of a center shaft fulcrum of the seesaw, the end tail of the seesaw is circular, so that the seesaw can be pushed to slide conveniently).

The length of each seesaw, the height of each spoke and the shape of the bottom surface of the basket surrounded by the spokes can be flexibly combined according to needs, and the lifting in the changed direction and the like which are simply changed according to the principle are not needed to be described in detail.

The automatic retractable bicycle basket has the beneficial effects that the width of the bicycle basket can be automatically changed in a retractable manner, and the bicycle using the system can automatically narrow the width of the bicycle basket when being stored; the bicycles after the bicycle basket is contracted can be regularly and automatically stored in the special bin box, so that good economic benefit and use convenience are brought; more importantly, the bicycle sharing system and other inventions of the team solve the problems of large occupied space of the shared bicycle and untidy appearance of the city.

Detailed Description

In the embodiment shown in fig. 1, the whole bicycle is a bicycle with other parts contracted according to the blade type shape, a rechargeable battery and a controller (a single chip microcomputer system) are arranged in the bicycle, and in order to enable the thickness of the contracted basket to be the smallest, the basket needs to be automatically contracted.

The bicycle basket is formed by L-shaped railings (2) which are surrounded into a circle by a plurality of railings, each L-shaped railing (2) is shaped like a seesaw, middle shaft fulcrums (3) of the seesaw are uniformly fixed on a seesaw fulcrum support (9), the plane of the seesaw support (9) is fixed on a bicycle basket support (8), edge strips (1) of the L-shaped railings form a circle when the seesaw railings (2) are basically laid flat, and the space surrounded by the circle is a bicycle basket space and is used for containing objects. The push plate (4) is provided with a nut (5), the nut (5) is sleeved on the screw rod (6), the screw rod (6) is connected with a shaft of the motor (7), the motor (7) is a speed-reducing direct current motor and is provided with an encoder, and the encoder is used for judging the distance of the nut (5) driven by the screw rod (6) to move so as to judge whether the push plate is in place or whether congestion exists midway (the motor runs for a period of time under the control of a single chip microcomputer such as STC15W4K56S, and the encoder represents the congestion without a displacement signal). In order to prevent the nut (5) from rotating together with the screw rod (6), the push plate rotation stopping sheet (10) is arranged on the bicycle basket support (8) and used for stopping the nut from rotating, so that the nut (driving the push plate) can only move up and down.

One end of the seesaw is pushed and pulled by a motor to ascend or descend: the specific principle is that a motor drives a push plate, the push plate and one end of a seesaw are flexibly connected through a steel wire (11) (a steel wire, a circular ring, a hinge and the like, the purpose of the flexible connection is that the end of the seesaw can be pulled to descend together when the push plate descends, the push plate is arranged at the lower part of a middle shaft pivot of the seesaw, the push plate (4) pushes one end of a seesaw railing (2) to move upwards (the end tail of the seesaw is circular and can be beneficial to sliding during pushing), when the push plate (4) presses all the seesaw railings (2), the whole seesaw railings are extended, and side bars (1) of the seesaw railings and the bottom edge of the seesaw railings form a vehicle basket together. At the moment, the seesaw railings cannot move up and down (one end of each seesaw railing is dead-pushed by the push plate, namely, one end of each seesaw railing is clamped between the plane where the seesaw fulcrum is located and the plane of the push plate, namely, the seesaws penetrate through the plane of the seesaw fulcrum, namely, the seesaws are arranged above and below the plane of the seesaw fulcrum at one side, and cannot swing left and right (the seesaw principle cannot swing left and right); in order to achieve the purpose of retracting the bicycle basket, the seesaw railings are erected, in order to erect the seesaw railings, the push plate (4) is pulled by the lead screw to move downwards under the action of the motor, one end of the seesaw needs to be pulled downwards by the push plate, the push plate moves linearly, and the tail end of the seesaw moves in an arc shape, so that the connection between the push plate and the tail end is realized by adopting flexible connection, namely, the connection with one end capable of changing the connection angle, in the embodiment, the steel wire (11) is used, namely, the push plate is connected with one end of the seesaw by the steel wire (11), and the description is convenient. When the push plate moves downwards, the steel wires on the push plate pull the tail ends of the corresponding teeterboards to move downwards to achieve the purpose of erecting the teeterboards, and after all the teeterboards are basically erected, the bicycle basket is retracted.

The bicycle basket is used as a component and is very simple to mount on the bicycle, namely, the bicycle basket bracket (8) is fixed at the front part of the bicycle frame by using screws; as for the bearing of the bicycle basket, only the L-shaped railing, namely the seesaw railing, needs to be thickened (the materials are generally stainless steel). In practice, the angle between the edge and the bottom side in the L-shaped railing is not necessarily 90 degrees, and the L-shaped railing can be contracted to be narrowest at the same height as the edge of the bicycle basket in a mode of being larger than 90 degrees (because the edge is inclined upwards after being contracted, the projection length in the horizontal direction is naturally small, and at the moment, when the L-shaped railing is extended to a proper position, an included angle also exists between the bottom side and the horizontal direction, namely, the whole bicycle basket is like the upper part of a funnel for pouring wine); the figure formed by connecting the seesaw fulcrums is the bottom surface of the bicycle basket, and can be in various shapes, preferably oval; as for the middle shaft structure of the seesaw railing, the structure is like a common seesaw, and a micro bearing is generally used, and the bearing is embedded into the plane of the seesaw support (9).

Transverse bars can be added among the seesaw railings (in the attached drawings, for simplicity, an oval bottom is adopted, so that the seesaw railings are not grouped), at the moment, the bottom surface of the bicycle basket is preferably a rounded rectangle, the rectangular same-side non-rounded corner parts (the rounded corner parts refer to the embodiment) form a group, the seesaw railings can lift at the same angle and in the same direction, the transverse bars can be added among the seesaw railings in the group, and a middle shaft fulcrum of some seesaws can be omitted; in order to avoid the long and wide seesaw railings from colliding with each other when being contracted, the heights of the long and wide seesaw railings are different by a few millimeters.

As above, the automatic scalability of the bicycle basket is realized under the control of the single chip microcomputer, namely, the bicycle basket components of the blade-shaped bicycle can be changed to be as thin as the blades, and because the thicker components of the bicycle are thinned, the whole bicycle is deformed to be as thin as the blades, and the thinned bicycle is very convenient and efficient to store.
