A new type of rotating and folding structure includes a first rotating body, a second rotating body and a folding device. The first and second rotating bodies are respectively provided with a rotating reference inclined surface and a rotating unfolding inclined surface that can be attached. The device includes a latch pin that can slide in a sliding groove at the lower part of the second rotating body, a latch reset spring that pushes the pin to reset in the direction of the rotation reference slope of the first rotating body, and a rotation that can drive the pin to slide away from the first rotating body. An unlocking piece for the reference slope; the rotation reference slope of the first rotating body is provided with an unfolding slot and a folding slot that can be inserted into and locked by the pins on the second rotating body in the unfolded and rotated and folded states, respectively; After the unlocking member is connected with the plug pin, the second rotating body is exposed outside of the force applying part.

In an improvement to the above-mentioned novel rotating and folding structure, the second rotating body includes a rod body and a rod seat fixedly connected to the bottom end of the rod body, and the rotating and unfolding inclined surface is provided on the bottom surface of the rod seat; One end of the rotating shaft is fixed to the rotation reference inclined surface of the first rotating body, and the other end is obliquely inserted into the rod seat and locked by a lock nut.

In an improved solution to the above-mentioned novel rotary folding structure, a protective cover is provided on the outer cover of the rod seat; an unlocking member accommodating recess is provided on the outer wall of the protective cover; the unlocking member is placed in the unlocking member accommodating recess Connect with the pin after the center.

Beneficial effect

Since the folding device includes three parts: the latch, the latch reset spring and the unlocking piece, and the first rotating body is provided with an unfolding slot and a folding slot for inserting and locking the latch in the unfolded and folded state, so that the vehicle can be aligned. The body can be rotated, folded and unfolded, so the structure of the utility model is simpler and more reasonable, and the production cost is lower.

The best mode of the present invention

The utility model is a new type of rotating and folding structure, as shown in Figures 1 to 4, comprising a first rotating body 1, a second rotating body 2 and a folding device 3, on the first and second rotating bodies 1, 2 respectively It is provided with a rotating reference inclined surface 11 and a rotating retractable inclined surface 21 that can be attached. After these two surfaces are attached together, they can be rotated around the rotation axis 4 to fold and unfold, which is the same as the current rotating and folding car body , The difference is: the folding device 3 includes a pin 31 that can slide in the chute 22 at the lower part of the second rotating body 2 and a pin that pushes the pin 31 to reset to the direction of the rotation reference slope 11 of the first rotating body 1 The reset spring 32 and the unlocking member 33 that can drive the bolt 32 to slide away from the rotation reference inclined surface 11 of the first rotating body 1; the rotation reference inclined surface 11 of the first rotating body 1 is provided in the unfolding, rotating and folding states respectively The lower end of the pin 31 on the lower second rotating body 2 is inserted into the locked unfolding slot 111 and the folding slot 112; after the lower part of the unlocking member 33 is connected with the pin 32, the lower part of the second rotating body 2 is exposed outside the force applying part . In this embodiment, the rotating and folding structure is applied to the scooter. At this time, the first and second rotating bodies 1 and 2 are the pedals and handle bars of the scooter respectively. There are two sets of folding devices and are symmetrically distributed on the vertical bars. Both sides are used to make the scooter more stable and firm in the unfolded and folded state. In addition, in this embodiment, the unlocking member 33 is a pulling member. In the unfolded state, the pin 31 is inserted into the unfolding slot 111 of the rotation reference slope 11 of the first rotating body 1; when the scooter is to be folded, the two Only fingers pinch the unlocking member 33 of the two sets of folding devices, and then pull the unlocking member 33 upward to make the pin 31 overcome the force of the pin reset spring 32 and then slide up, when the pin 31 slides to its lower end and leaves the unfolding slot 111 Then, you can rotate the second rotating body 2 around the rotating shaft 4 to lean against the first rotating body 1; as long as you rotate it a little bit, you can loosen the unlocking piece first, and then continue to rotate. When the pin 31 is rotated to the pin reset spring 32 When the inner (lower) end slides into the folding slot 112 of the first rotating body 1 under the action of, the folding of the car body is completed, as shown in FIG. 2. When the scooter is to be unfolded, it is also used to pull the latch on the unlocking member to unlock, and then the second rotating body can be rotated to unfold.

It can be seen from the above that the folding device 3 includes three parts: the latch 31, the latch reset spring 32, and the unlocking member 33, and the rotation reference slope 11 of the first rotating body 1 is provided with a latch for inserting and locking in the unfolded and folded state. The unfolding slot 111 and the folding slot 112 can realize the rotating folding and unfolding of the vehicle body. Therefore, the structure of the present invention is simpler and more reasonable, and the production cost is lower.

Embodiments of the present invention

In this embodiment, the second rotating body 2 includes a rod body 23 and a rod seat 24 fixedly connected to the bottom end of the rod body 23, and the rotating and expanding inclined surface 21 is provided on the bottom surface of the rod seat 24; One end of the rotating shaft is fixed to the rotation reference inclined surface of the first rotating body, and the other end is obliquely inserted into the rod seat 24 and locked by the lock nut 5. In order to make the use of the folding device safer (to prevent children's fingers from being caught in the slide groove, etc.) and more beautiful (the appearance of the rod seat is affected by the slide groove and the nut falling into the hole on the rod seat), The rod base 24 is covered with a protective cover 6; an unlocking member accommodating recess 61 is provided on the outer wall of the protective cover 6; the unlocking member is placed in the unlocking member accommodating recess 61 and then connected to the plug 31.

The unlocking member 33 can also be a pushing member. At this time, its movement direction and the movement direction of the plug pin are basically at an angle of 90 degrees. For this reason, inclined surfaces are often used to realize the conversion of the lateral movement of the pushing member into a pair of plug pins. Move vertically.
