Detailed Description

In order to facilitate the understanding of those skilled in the art, the invention will be further described with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 5, a folding structure of scooter is mainly applied to the scooter, and comprises a planar link mechanism, wherein the planar link mechanism comprises a pedal seat 1 and a handle rod 2, the handle rod 2 is hinged on the pedal seat 1, and the handle rod 2 can vertically rotate on the pedal seat 1.

Specifically, handle pole 2 articulates on pedal seat 1 through first pivot 71, rotates handle pole 2, and handle pole 2 is collapsible or expand on pedal seat 1, and handle pole 2 has folding position and expansion position on pedal seat 1 in other words, and it has solved the scooter and is not convenient for carry, problem that occupation space is big.

When the handle rod 2 is in the folding position, the included angle between the handle rod 2 and the pedal seat 1 is approximately 0 degree; the angle between the handle bar 2 and the pedal seat 1 is substantially 90 deg. when the handle bar 2 is in the deployed position.

The plane link mechanism further comprises a driven piece, the driven piece is connected between the pedal seat 1 and the handle rod 2, when the handle rod 2 is folded on the pedal seat 1, the plane link mechanism is located at a dead point position, the pressure angle is 90 degrees at the moment, the acting force or the moment of the handle rod 2 on the driven piece is zero, and the handle rod 2 cannot drive the driven piece to move, so that the pedal mechanism is equivalent to the situation that the handle rod 2 is fixedly arranged on the pedal seat 1.

When the handle rod 2 is unfolded on the pedal seat 1, the plane link mechanism is also positioned at a dead point position, the pressure angle is 90 degrees at the moment, the acting force or the moment of the handle rod 2 on the driven piece is zero, and the handle rod 2 cannot drive the driven piece to move at the moment, so that the pedal seat 2 is equivalent to the handle rod 2 fixedly arranged on the pedal seat 1.

In this scooter's beta structure, when the scooter is folding or expand on pedal seat 1, plane link mechanism is in the dead point position, handle pole 2 and pedal seat 1 are fixed to be set up together, the unable direct drive handle pole 2 of user rotates on pedal seat 1, but accessible follower drive handle pole 2 rotates on pedal seat 1, for the connection structure of boss dimple among the prior art, this scooter's beta structure has the advantage that the structure is retrencied, firm in connection is reliable and easy operation.

The plane link mechanism can be a crank rocker mechanism or a crank slider 4 mechanism, specifically, the plane link mechanism is a plane four-bar mechanism, the driven member comprises a connecting rod 3 and a slider 4, the pedal seat 1, the handle rod 2, the connecting rod 3 and the slider 4 form the plane four-bar mechanism, the connecting rod 3 is hinged on the pedal seat 1 through a second rotating shaft 72, the rotating direction of the connecting rod 3 on the pedal seat 1 is consistent with the rotating direction of the handle rod 2 on the pedal seat 1, the slider 4 is hinged on the connecting rod 3 and is arranged on the handle rod 2 in a sliding manner, the slider 4 is hinged on the connecting rod 3 through a third rotating shaft 73, and the rotating direction of the slider 4 on the connecting rod 3 is consistent with the rotating direction of the connecting rod 3 on the.

When the handle rod 2 is folded or unfolded on the pedal seat 1, the sliding direction of the sliding block 4 and the rotating direction of the connecting rod 3 are positioned on the same straight line, the pressure angle is 90 degrees at the moment, a user cannot directly drive the handle rod 2 to rotate, and the handle rod 2 and the pedal seat 1 are equivalently fixedly arranged together.

When handle pole 2 and pedal seat 1 are fixed to be set up together, the user can directly drive slider 4 and slide on handle pole 2 for plane link mechanism breaks away from the dead point position, makes things convenient for handle pole 2 to adjust between folding position and expansion position, further makes things convenient for this scooter's beta structure's operation.

The limiting groove 11 has been seted up on the pedal seat 1, the lower extreme of handle bar 2 is inserted and is established at limiting groove 11, first pivot 71 is located limiting groove 11, when handle bar 2 is folding on pedal seat 1, handle bar 2 butt is on the inside wall of limiting groove 11 one side, and when handle bar 2 expandes on pedal seat 1, handle bar 2 butt is on the inside wall of limiting groove 11 opposite side, limiting groove 11 plays the effect of injecing handle bar 2 turned angle on pedal seat 1, also make things convenient for handle bar 2 to fix a position folding position or expand the position fast at the rotation in-process.

An elastic piece 6 is arranged between the handle rod 2 and the sliding block 4, specifically, the elastic piece 6 is a spiral spring, the elastic piece 6 can force the handle rod 2 to keep abutting against the inner side wall, so that the handle rod 2 keeps folding or unfolding on the pedal seat 1, specifically, when the handle rod 2 is folded on the pedal seat 1 and abuts against the inner side wall of one side of the limiting groove 11, the handle rod 2 keeps abutting against the inner side wall of the side of the limiting groove 11 under the elastic force of the elastic piece 6; when the handle rod 2 is unfolded on the pedal base 1 and abuts against the inner side wall of the other side of the limiting groove 11, the handle rod 2 is kept to abut against the inner side wall of the side of the limiting groove 11 under the action of the elastic piece 6.

The scooter is in-service use, and slider 4 can receive vibrations, rock the effect of other unmanned external forces such as, and this kind of unmanned external force can be offset to elastic component 6, avoids slider 4 to drive plane link mechanism under the effect of unmanned external force and breaks away from the dead point position, has improved the reliability and the security that the beta structure of scooter used.

The slider 4 is provided with a placement groove 42, the elastic piece 6 is arranged in the placement groove 42, the handle rod 2 is detachably provided with a positioning rod 74, one end of the elastic piece 6 abuts against the inner bottom of the placement groove 42, the other end of the elastic piece 6 abuts against the positioning rod 74, and the elastic piece 6 is conveniently disassembled and assembled in the placement groove 42 through the disassembling and assembling positioning rod 74.

Connecting rod 3 sets up in spacing groove 11, avoids connecting rod 3 to expose outside and takes place the problem of the dead connecting rod 3 of foreign matter card, has improved the reliability that this plane link mechanism used, has also improved the aesthetic property of this scooter's beta structure.

Handle bar 2 includes hollow body 21, slider 4 slides and sets up in body 21, slider 4 can slide in body 21 on the length direction of body 21, slider 4 adopts built-in structural design, avoid plane link mechanism directly to expose outside and take place the problem of the dead plane link mechanism of foreign matter card, the reliability that this plane link mechanism used has been improved, in addition, the design of slider 4 built-in body 21 has also improved the compactedness of structure, occupation space has been reduced, consequently, this scooter's beta structure has reliable operation, occupation space is little and pleasing to the eye advantage.
