Description

Fold mechanism safety device, fold mechanism and scooter

Technical field

The utility model relates to fold mechanism safety device, fold mechanism and scooters.

Background technique

The fold mechanism of existing scooter is in folding process, the problem of being easy to produce clamp hand, is not involved with correlation It can prevent the structure of clamp hand from jamming a finger to avoid when turning folding.

Utility model content

The utility model relates to fold mechanism safety device, fold mechanism and scooters, and clever structure is easy to use, It is simple to operation, clamp hand can be effectively prevent.

The utility model is achieved through the following technical solutions:

Fold mechanism safety device is applied to fold mechanism, and fold mechanism includes the first connector, on the first connector Offer the first limiting slot, comprising: safety post and elastic component, the safety post are movably installed on the first connector, safety post One end against or connection elastic component, the other end stretched out from the bottom wall of the first limiting slot, elastic component is directly or indirectly connected to the On a connection piece.

By using above-mentioned technical proposal, the setting of safety device is beneficial to prevent clamp hand, specifically, hand can be prevented to be in When in the first limiting slot, because rotate first connector due to the clamp hand problem that generates.The specific structure of safety device, as safety post can In the first limiting slot, the effect centainly filled and led up is played to the first limiting slot, hand is not easy to protrude into the first limiting slot, can effectively prevent When only fold mechanism is in unfolded state, the clamp hand problem that generates when rotating the first connector.

The first connector offers through-hole eight in the position of the first limiting slot as a further improvement of the utility model, The 4th limiting section for being limited to safety post is provided in through-hole eight.By using above-mentioned technical proposal, safety post peace , can be movable in through-hole eight loaded in through-hole eight, and due to the effect of elastic component, make safety post out against in the 4th limiting section On, so that safety post end is stretched out from the bottom wall of the first limiting slot, prevent clamp hand.

The 4th limiting section is step as a further improvement of the utility model, and having on the safety post can be with Another step that step leans.By using above-mentioned technical proposal, the step of step and the 4th limiting section on safety post can It abuts each other and connects, to be limited to safety post, clever structure.

As a further improvement of the utility model, further include third cover board, elastic component one end against or be connected to safety Column, the other end against or be connected to third cover board, third cover board is anchored on the first connector by fastener.By using above-mentioned Technical solution, the setting of third cover board are conducive to the fixation of elastic component, are conducive to the installation of safety post.

As a further improvement of the utility model, on the first connector, in the position of installation third cover board, offer recessed Slot five.By using above-mentioned technical proposal, the setting of groove five is conducive to the setting of third cover board, may make third cover board Surface is flushed with the surface of the first connector, to not generate interference with the second connector in rotation process.

Third cover board is arc-shaped in length as a further improvement of the utility model,.It is long by using above-mentioned technical proposal Circular cover is adapted to the lower part outer rim of the first connector, is easily installed.

Fluted or pillar is opened up on safety post as a further improvement of the utility model, to connect or against elasticity Part.By using above-mentioned technical proposal, the setting of groove or pillar is conducive to the connection of elastic component or against transporting safety post It moves and restores reliable and stable.

The elastic component is second spring as a further improvement of the utility model,.By using above-mentioned technical proposal, Elastic component uses spring, is easily installed and resets.

Fold mechanism further includes the second connection including fold mechanism safety device described in any of the above-described scheme Part, and, the lock core to relatively rotate for limiting the first connector and the second connector；Have second on first connector Limiting slot has groove three on the second connector；Lock core includes interconnecting piece and sticking department, and interconnecting piece is in the first connector and It can slide at the center of rotation of the relative rotation of two connectors and along the axial direction of center of rotation, the butt of sticking department, which connects, to be connected Socket part simultaneously extends outwardly；When fold mechanism is in the lock state of expansion, the sticking department of lock core is limited the second of the first connector The groove three of position slot and the second connector locks, and the end of safety post is stretched out from the bottom wall of the first limiting slot.By using above-mentioned Technical solution, fold mechanism clever structure, the first connector are rotatably connect with the second connector, sticking department on lock core For the position of two connectors to be fixed, make not rotate, sound construction；The interconnecting piece of lock core is slidingly arranged at On a connection piece or the second connector, lock core can be relative to the axial direction hair at the center of rotation of the first connector and the second connector Raw movement, the interconnecting piece of lock core are at the center of rotation of two connectors, i.e., the position of lock core is in the rotation connection of two connectors Position keep lock core mobile by operating the lock core of the position, fold mechanism can be made to realize expansion or fold, compared to lock Core is located at for the fold mechanism of other positions, for the user, convenient and intuitive using more smoothly, controllability It is stronger, and overall structure is stronger compact；And the butt of sticking department connects interconnecting piece and extends outwardly, it specifically, can be along rotation The radial direction at center extends, and can extend perpendicular to interconnecting piece, also can be tilted at interconnecting piece and extend outwardly；It may make sticking department pair The locking of second limiting section and third limiting section is more direct, smooth, firm, keeps the fold mechanism of unfolded state stronger, mentions High security.When fold mechanism is in unfolded state, because the first limiting slot is in exposure position, hand holds during operation Easily sink into the first limiting slot, when rotating the first connector, is also easy to produce clamp hand problem, and the setting of safety device, safety post End is stretched out from the bottom wall of the first limiting slot, has filled and led up the first limiting slot, finger is not easy to protrude into the first limiting slot, to rotate When the first connector, clamp hand is not led to the problem of.

Scooter, including fold mechanism described in above scheme, further include vehicle frame, and the first connector is connected to the side of scooter To bar, the second connector is connected to the vehicle frame of scooter or is integrally formed with vehicle frame.By using above-mentioned technical proposal, scooter When folding, when rotating the first connector, clamp hand is not led to the problem of.

Compared with the existing technology, the advantages of the utility model safety device, fold mechanism and scooter place at least: knot Structure is ingenious, and rationally, folding and expanding is convenient, and does not lead to the problem of clamp hand when folding, easy to promote and utilize.

For the above and other objects, features and advantages of the utility model can be clearer and more comprehensible, preferable reality is cited below particularly Example is applied, and cooperates institute's accompanying drawings, is described in detail below.
