The fixing member 30 forms a first protruding post 32 and a flange portion 34 at two opposite ends, respectively. The first protruding post 32 can be coupled to the rotary member 40, and the flange portion 34 can pass through the mounting hole 232 of another side board 230 and be secured in the hinge hole 322 corresponding to the mounting hole 232 of another side board 230.
The rotary member 40 is substantially a cylindrical body, and forms a second protruding post 41 and an accommodation groove 43 at two opposite ends, respectively. The second protruding post 41 can be rotatably received in the receiving groove 17, and the first protruding post 32 can be received in the accommodation groove 43. In addition, the rotary member 40 further defines a latching slot 44 adjacent to the second protruding post 41. A spring 47 is received in the latching slot 44 for urging the sliding member 50. Further, a peripheral wall of the rotary member 40 forms a plurality of latching rings 46, and a notched groove 461 is defined between two adjacent latching rings 46.
The sliding member 50 is configured to secure the shaft 10 and the rotary member 40. In at least one embodiment, the sliding member 50 includes a stopper portion 51 and a barrel 52. The stopper portion 51 is disposed around an end of the barrel 52. The barrel 52 defines an accommodation hole 55 to allow the rotary member 40 to pass through the barrel 52. A resisting block 53 protrudes inwardly from an inner wall of the accommodation hole 55, and extends out of the barrel 52. The resisting block 53 is configured to be latched into the latching slot 44 and resist the spring 47. Additionally, the resisting block 53 can be received in the latching groove 19 to lock the shaft 10 and the rotary member 40.
The shank 60 is rotatably coupled to the vehicle bracket 200, and includes a plurality of teeth 61, a connecting shaft 62, and an operating portion 63.

In at least one embodiment, an end of the shank 60 where the plurality of teeth 61 are formed on is substantially arc-shaped to facilitate engagement between the plurality of teeth 61 and the notched grooves 461. The connecting shaft 62 can be rotatably received in the pinhole 259 to allow the shank 60 to be rotatably coupled to the vehicle bracket 200. A user may apply a force to the operating portion 63 to actuate the shank 60.
The urging member 70 includes a connecting portion 71 and a button 73. The connecting portion 71 is substantially L-shaped, a first end of the connection portion 71 forms a pushing block 711 to resist the stopper portion 51, and a second end of the connection portion 71 forms a wedge 712 having an inclined plane 713. A plurality of guide pins 715 are formed on the connecting portion 71 and can slide in the guiding groove 254. The button 73 is slidably mounted on the cover 210. The button 73 includes a resisting plane 732 engaging the inclined plane 713 and a pressing portion 734 received in the button hole 211.
In assembly, referring to FIG. 5, the latching portion 15 passes through the mounting hole 232 of one side board 230 and is secured in the hinge hole 322 corresponding to the mounting hole 232. The flange portion 34 passes through the mounting hole 232 of another side board 230 and is secured in another hinge hole 322. The first protruding post 32 is received in the accommodation groove 43, and the second protruding post 41 is rotatably received in the receiving groove 17. The sliding member 50 is fitted around an end of the rotary member 40, and then the resisting block 53 resists the spring 47. The resisting block 53 and the spring 47 sliding member 50 and the spring are jointly latched into the latching slot 44. The resisting block 53 resists an end of the shaft 10 near the receiving groove 17 and is not received in the latching groove 19 because of an elastic force of the spring 47. The shank 60 is rotatably received in the pinhole 259 via the connecting shaft 62 to rotatably fix to the vehicle bracket 200. The urging member 70 slides in the guiding groove 254 via the guide pin 715, thereby connecting the connecting portion 71 to the vehicle bracket 200. At this time, the pushing block 711 is coplanar with and spaced from the stopper portion 51. Additionally, the button 73 is slidably mounted on the cover 210, the first end of the torsion spring 20 is fixed in the fixing hole 252 of the fixing sheet 251, and a second end of the torsion spring 20 is latched on the latching post 11. In an initial state, the vehicle bracket 200 is fixed to the connecting board 300 and can be detached from the connecting board 300 by the potential energy of the torsion spring 20.
In use, referring to FIG. 1 and FIG. 6, the plurality of teeth 61 engage the notched grooves 461 by actuating the operating portion 63 to rotate the vehicle bracket 200 and the rotary member 40. When the vehicle bracket 200 is detached from the connecting board 300, the vehicle bracket 200 and the rotary member 40 rotate relative to the shaft 10 and fixing member 30. Since the resisting block 53 resists the spring 47 and are jointly latched into the latching slot 44, the sliding member 50 can continuously rotate with the rotary member 40. When the rotary member 40, the sliding member 50, and the vehicle bracket 200 rotate a first predetermined angle, the resisting block 53 is aligned with the latching groove 19. Due to the elastic force of the spring 47, the resisting block 53 drives the sliding member 50 to slide towards the shaft 10 until the resisting block 53 is received in the latching groove 19. The stopper portion 51 moves towards the pushing block 711 to contact or keep a space with the pushing block 711. At this time, the shaft 10, the rotary member 40, the sliding member 50, and the vehicle bracket 200 are in a locking state. That is, the vehicle bracket 200 cannot rotate.
In order to adjust the angle of the vehicle bracket 200, the plurality of teeth 61 disengage the notched grooves 461 by actuating the operating portion 63. Then, the vehicle bracket 200 is not directed by the rotary member 40 to rotate the vehicle bracket 200 a second adjustment angle. The operating portion 63 can be actuated again to fix the vehicle bracket 200. At this time, the teeth 61 engage the notched grooves 461, and the rotary member 40 and the vehicle bracket 200 are locked again. Thus, mobile telephones or books (not shown) can be securely placed on the vehicle bracket 200.
When the vehicle bracket 200 is not in use, the button 73 is actuated to allow the inclined plane 713 to resist the resisting plane 732. Thus, the connecting portion 71 moves towards the fixing member 30, and then drives the pushing block 71 to move towards the stopper portion 51 until the pushing block 71 resists the stopper portion 51. Thus, the sliding member 50 slides towards the fixing member 30 to allow the resisting block 53 to be disengaged the latching groove 19. At this time, the shaft 10 and the rotary member 40 is a unlocking state, and the vehicle bracket 200 can return the initial state by manually pushing the vehicle bracket 200. In at least one embodiment, a rotational angle of the vehicle bracket 200 is substantially equal to the sum of the first predetermined angle and the second adjustment angle.
When the vehicle bracket 200 is used again, since the vehicle bracket 200 is fixed to the shank 60, the shank 60 latches the rotary member 40, and the rotary member 40 latches the sliding member 50. Thus, the rotary member 40, the sliding member 50, and the vehicle bracket 200 directly rotate a third angle relative to the shaft 10. The third angle is equal to the sum of the first predetermined angle and the second adjustment angle.
In summary, the sliding member 50 engages the shaft 10 through the engagement between the resisting block 53 and the latching groove 19, and the shank 60 latches the rotary member 40 through the engagement between the plurality of teeth 61 and the notched grooves 461. Thus, the vehicle bracket 200 has an angle memory function and can be fixed at a preset angle. Therefore, the rotary assembly 100 is both efficient and convenient.
