DETAILED DESCRIPTION
Please refer to FIG. 1 and FIG. 2. FIG. 1 is an exploded diagram of an electronic device 10 according to an embodiment of the disclosure. FIG. 2 is an assembly diagram of the electronic device 10 according to the embodiment of the disclosure. The electronic device 10 includes a first board structure 12 whereon at least one fixing hole 121 is formed, a second board structure 14 and a pivoting mechanism 16. In the embodiment of the disclosure, the first board structure 12 can be a screen, and the second board structure 14 can be a host. An end of the pivoting mechanism 16 pivots adjacent to a middle of the first board structure 12, and the other end of the pivoting mechanism 16 pivots to a side of the second board structure 14. Therefore, the first board structure 12 can pivot relative to the pivoting mechanism 16 within a range between 0 degree and 360 degrees, and the second board structure 14 can pivot relative to the pivoting mechanism 16 within a range between 0 degree and 180 degrees. In addition, the electronic device 10 further includes a fixing mechanism 18 installed on the pivoting mechanism 16 for constraining rotation of the first board structure 12 relative to the pivoting mechanism 16, so as to position an angle of view of the first board structure 12 according to demand.
Please refer to FIG. 3A and FIG. 3B. FIG. 3A and FIG. 3B are diagrams of the fixing mechanism 18 in different operating modes according to a first embodiment of the disclosure. The fixing mechanism 18 includes a base 20 fixed inside the pivoting mechanism 16, and a pin 22 disposed on the base 20 in a slidable manner for inserting into the fixing hole 121 on the first board structure 12, so as to constrain the rotation of the first board structure 12 relative to the pivoting mechanism 16. In the first embodiment, the pin 22 can be made of metal material or plastic material having sufficient strength, so as to bear shearing stress generated from the first board structure 12 when pivoting relative to the pivoting mechanism 16. The fixing mechanism 18 further includes a latch 24 disposed on the base 20 in a slidable manner and contacting against the pin 22 for sliding the pin 22 relative to the base 20, a button 26 disposed on the latch 24, and a resilient component 28 disposed between the pin 22 and the base 20. The resilient component 28 can contact against the base 20 and sheath on the pin 22.
In the first embodiment, the fixing mechanism 18 can be switched between a releasing mode and a constraining mode. When the button 26 is pushed, the latch 24 slides the pin 22 relative to the base 20 by the button 26, so that the pin 22 is inserted into the fixing hole 121 on the first board structure 12. Meanwhile, the resilient component 28 is compressed for storing a resilient recovering force, and the first board structure 12 can not pivot relative to the pivoting mechanism 16. When the button 26 is released, the resilient recovering force of the resilient component 28 can be for pushing the pin 22 out of the fixing hole 121 on the first board structure 12, so as to release the constrain of the first board structure 12 relative to the pivoting mechanism 16. Thus, the fixing mechanism 18 can further include a tenon 30 disposed on the latch 24. The tenon 30 can be engaged with an engaging portion 201 of the base 20. An engagement of the tenon 30 and the engaging portion 201 can resist the resilient recovering force of the resilient component 28 when the pins 22 stops sliding relative to the base 20, so as to prevent the latch 24 from sliding relative to the base 20. The tenon 30 can be a resilient protrusion, and the engaging portion 201 of the base 20 can be a rib structure. That is to say, in the first embodiment of the disclosure, an initial position of the pin 22 is located inside the base 20 when the button 26 is not pushed. The pin 22 is pushed outwardly for inserting into the fixing hole 121 on the first board structure 12 when the button 26 is pushed.
The fixing mechanism 18 can be implemented as at least two types. Please refer to FIG. 4A and FIG. 4B. FIG. 4A and FIG. 4B are diagrams of the fixing mechanism 18 in different operating modes according to a second embodiment of the disclosure. The fixing mechanism 18 of the second embodiment includes the base 20, the pin 22, the latch 24, the button 26 and a resilient component 32. In this embodiment, elements having the same numerals as ones of the above-mentioned embodiment have the same structures and function, and detailed description is omitted herein for simplicity. Difference between the first embodiment and the second embodiment is that the resilient component 32 is disposed between the latch 24 and the base 20 for driving the latch 24 to insert the pin 22 into the fixing hole 121 on the first board structure 12, so as to prevent the first board structure 12 from pivoting relative to the pivoting mechanism 16. The button 26 can be pushed for sliding the latch 24 relative to the base 20, so as to move the pin 26 out of the fixing hole 121 on the first board structure 12 to unlock the fixing mechanism 18. Meanwhile, the resilient component 32 is compressed, and the resilient recovering force of the resilient component 32 can be for ejecting the pin 22 from the base 20 when the button 26 is not pushed.
The fixing mechanism 18 of the second embodiment does not constrain the latch 24 to slide relative to the base 20. When the pin 26 separates from the fixing hole 121, the first board structure 12 can pivot relative to the pivoting mechanism 16, so as to misalign the fixing hole 121 on the first board structure 12 with the pin 26. Thus, the pin 26 is not inserted into the fixing hole 121 when the button 26 is not pushed and the pin 26 is ejected from the pivoting mechanism 16 by the resilient recovering force of the resilient component 32, so that the first board structure 12 can pivot relative to the pivoting mechanism 16 without constrain. In the second embodiment of the disclosure, the initial position of the pin 22 is protruding out of the base 20. The button 26 is pushed for moving the pin 22 out of the fixing hole 121 on the first board structure 12. The condition type of the fixing mechanism 18 is not limited to the above-mentioned embodiment, and relates to design demand.
Please refer to FIG. 5, FIG. 6, FIG. 7 and FIG. 8. FIG. 5 to FIG. 8 are diagrams of the electronic device 10 in different operating modes according to the embodiment of the disclosure. In the embodiment of the disclosure, the first board structure 12 can be the screen, and the second board structure 14 can be the host. However, the disclosure is not limited to the above embodiment, for example, the second board structure 14 can be another screen. As shown in FIG. 5, the first board structure 12 of the electronic device 10 is fixed on the pivoting mechanism 16, the first board structure 12 and the pivoting mechanism 16 can pivot relative to the second board structure 14 synchronously, and the electronic device 10 can act as a notebook computer. As shown in FIG. 6, the fixing mechanism 18 can be for releasing the constrain of the first board structure 12 relative to the pivoting mechanism 16, so that the first board structure 12 can pivot relative to the pivoting mechanism 16 within the range between 0 degree and 360 degrees. As shown in FIG. 7, the first board structure 12 is fixed on the pivoting mechanism 16 by the fixing mechanism 18 when the first board structure 18 pivots from a position shown in FIG. 5 to 180 degrees for reverse rotation. Meanwhile, the first board structure 12 and the pivoting mechanism 16 can pivot relative to the second board structure 14 synchronously, so that a view angle of the first board structure 12 shown in FIG. 7 is inverse with respect to the view angle of the first board structure 12 shown in FIG. 5. For example, the electronic device 10 can act as a tablet computer shown in FIG. 8 when the first board structure 12 is close to the second board structure 14.
Comparing to the prior art, the electronic device of the disclosure disposes the fixing mechanism inside the pivoting mechanism, so that the first board structure (such as the screen) can have sufficient space for containing a large size panel. In addition, the disclosure has advantages of simple mechanical design and easy operation, so as to decrease manufacturing cost and to increase operating convenience of the electronic device.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention.
