[ detailed description ] embodiments

The utility model relates to a novel rotatory beta structure, as shown in fig. 1 to 4, including first rotator 1, second rotator 2 and folding device 3 be equipped with the rotation benchmark inclined plane 11, the rotatory inclined plane 21 of taking up and opening out that can laminate on first, the two

rotators

1, 2 respectively, these two faces of them are laminated together the back, can receive, expand around rotation axis 4 rotation, and this is the same with current rotatory folding automobile body, and the difference is: the folding device 3 comprises a latch 31 capable of sliding in the chute 22 at the lower part of the second rotating body 2, a latch return spring 32 for pushing the latch 31 to return to the direction of the rotating reference inclined plane 11 of the first rotating body 1, and an unlocking piece 33 capable of driving the latch 32 to slide away from the rotating reference inclined plane 11 of the first rotating body 1; an unfolding slot 111 and a folding slot 112 are arranged on the rotation reference inclined plane 11 of the first rotating body 1, and the lower ends of the bolts 31 on the second rotating body 2 in the unfolding and folding states can be inserted and locked respectively; the lower part of the unlocking member 33 is connected to the latch 32, and the urging part thereof is exposed to the lower part of the second rotating body 2. In this embodiment, rotatory beta structure is applied to the scooter on, and first, two

rotators

1, 2 are the footboard and the handlebar pole of scooter respectively this moment, and folding device has two sets and symmetric distribution in the both sides of montant to make the scooter more steady, firm when expansion, fold condition. In addition, in the present embodiment, the unlocking member 33 is a pulling member, and in the unfolded state, the latch 31 is inserted into the unfolding slot 111 of the rotation reference slope 11 of the first rotating body 1; when the scooter is folded, two fingers pinch the unlocking piece 33 of the two folding devices, then the unlocking piece 33 is pulled upwards to enable the bolt 31 to overcome the acting force of the bolt resetting spring 32 and slide upwards, and when the bolt 31 slides to the lower end and leaves the unfolding slot 111, the second rotating body 2 can be rotated around the rotating shaft 4 to lean against the first rotating body 1; the unlocking member can be released only by slightly rotating, and then the vehicle body can be folded when the latch 31 is rotated to slide the inner (lower) end into the folding slot 112 of the first rotating body 1 under the action of the latch return spring 32, as shown in fig. 2. When the scooter is to be unfolded, the unlocking piece is also acted on to pull the bolt to unlock, and then the second rotating body can be rotated to unfold.

From the above, it can be seen that the folding device 3 includes three parts of the latch 31, the latch return spring 32 and the unlocking member 33, and the unfolding slot 111 and the folding slot 112 for unfolding and locking the latch in the folded state are provided on the rotation reference inclined plane 11 of the first rotating body 1, so that the rotary folding and unfolding of the vehicle body can be realized, therefore, the utility model has the advantages of simpler and more reasonable structure and lower production cost.

In this embodiment, the second rotator 2 includes a rod 23 and a rod seat 24 fixedly connected to a bottom end of the rod 23, and the rotating foldable slope 21 is disposed on a bottom surface of the rod seat 24; one end of the rotation shaft is fixed to a rotation reference slope of the first rotating body, and the other end is locked by a locking nut 5 after being inserted obliquely into the rod seat 24. In order to make the folding device more safe to use (prevent fingers of children from being clamped in the sliding grooves, etc.) and more beautiful (the appearance of the rod seat is influenced due to the sliding grooves, nut falling holes, etc. formed on the rod seat), a protective cover 6 is covered outside the rod seat 24; an unlocking piece accommodating concave part 61 is arranged on the outer wall of the protective cover 6; the unlocking member is placed in the unlocking member receiving recess 61 and then coupled to the latch 31.

The unlocking member 33 may also be a pushing member, and its moving direction is substantially at an angle of 90 degrees to the moving direction of the bolt, for which purpose the pushing member is usually pushed by an inclined surface to convert the lateral movement of the pushing member into the vertical movement of the bolt.

Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims. Therefore, the detailed description of the embodiments of the present disclosure is to be construed as merely illustrative, and not limitative of the present disclosure, but rather to limit the scope thereof by the appended claims.
