As shown in fig. 1 to 3, in an embodiment of the invention, the electronic device 100 is, for example, a tablet computer. The electronic device 100 includes a housing 110, a screen 120 and a supporting structure 1. The housing 110 is a casing of the electronic device 100 for protecting internal components. The housing 110 includes a housing rim 111 and an inner housing 112. The inner housing 112 is an inner case of the electronic device 100 for accommodating and placing internal components; the inner case 112 of the present invention forms a receiving space around the support structure 1 to receive the support structure 1. The screen 120 is located on the housing 110 for a user to view a picture and perform touch control.
In an embodiment of the present invention, the supporting structure 1 has a small volume and does not excessively occupy the space of the inner housing 112 of the electronic device 100, which can be easily operated by a user, and the supporting structure 1 can rotate and expand relative to the housing 110 to stably support the electronic device 100. The support structure 1 of the invention is located at the housing edge 111 and within the inner housing 112, and part of the elements of the support structure 1 are connected to the wall of the inner housing 112. The supporting structure 1 includes a supporting member 10, a rotating shaft 40, a ratchet 30, a locking member 20 and an unlocking member 50.
In one embodiment of the present invention, the supporting member 10 is a rectangular thin plate connected to the rotating shaft 40 and pivotally connected to the housing edge 111 of the housing 110 through the rotating shaft 40. The housing 110 can rotate relative to the support 10 by pivoting the shaft 40. When the housing 110 is rotated along the rotation direction X to be close to the supporting member 10, the overall appearance of the electronic device 100 appears as a common tablet computer; when the housing 110 rotates along the direction opposite to the rotation direction X to an angle that is opened relative to the supporting member 10, the supporting member 10 can serve as a base to support the housing 110, so as to erect the electronic device 100.
As shown in fig. 1 to 3 and 5, in an embodiment of the present invention, the locking member 20 is used to lock with the ratchet 30, so as to keep the opening angle of the supporting member 10 relative to the housing 110 stable. The fastener 20 includes a fastener 21, a fastener rod 22 and a fastener torsion spring 23. The locking piece 21 is used for locking the ratchet 30, and the locking piece 21 includes an inclined surface 211. The fastening piece rod 22 is connected with the fastening piece 21. The fastening member torsion spring 23 connects the inner housing 112 of the housing 110 and the fastening member rod 22, the fastening member torsion spring 23 is used for providing a first torsion to drive the fastening member rod 22 to rotate along a first rotation direction a, and the rotating fastening member rod 22 drives the fastening piece 21 to rotate to the fastening ratchet 30. In an embodiment of the invention, the fastening member torsion spring 23 is sleeved on the fastening member rod 22, and when the fastening piece 21 rotates by a force in a direction opposite to the first rotation direction a, the fastening member torsion spring 23 stores energy and generates a first torsion force due to a bending stress in the opposite direction.
In an embodiment of the present invention, one end of the rotating shaft 40 is pivotally connected to the housing 110, and the other end of the rotating shaft 40 is connected to the supporting member 10. The rotating shaft 40 includes a shaft body 41 and a shaft torsion spring 42. The shaft body 41 is connected to the ratchet 30. The shaft torsion spring 42 is connected to the shaft 41, and the shaft torsion spring 42 is used for providing a second torsion force to drive the shaft 41 to rotate along a second rotation direction B and drive the ratchet 30 connected to the shaft 41 to rotate along the second rotation direction B. The first rotational direction a is opposite the second rotational direction B. In an embodiment of the invention, the shaft torsion spring 42 is sleeved on the shaft 41, and when the shaft 41 rotates by a force in a direction opposite to the second rotation direction B, the shaft torsion spring 42 stores energy and generates a second torsion force due to a bending stress in the opposite direction.
In an embodiment of the present invention, as shown in fig. 3 to 5, the ratchet 30 is connected to the shaft 41. The ratchet 30 includes a plurality of ratchet teeth 31. Each ratchet tooth 31 includes a flat surface 311, an arc surface 312, and a peak 314. A top end of the flat surface 311 and a top end of the arc surface 312 of each ratchet tooth 31 are connected to form the crest 314. A bottom end of the plane 311 of each ratchet 31 is connected with a bottom end of the arc surface 312 of another adjacent ratchet 31 to form a tooth valley 313; the valleys 313 are used to lock the locking piece 21 rotating along the first rotation direction a. The valleys 313 and peaks 314 are staggered to form a sawtooth moving surface.
As shown in fig. 3, 5 and 6, when the ratchet 30 rotates in the opposite second rotation direction B, the arc surface 312 of the ratchet 31 lifts the locking piece 21 to make the locking piece 21 leave the valley 313 and drive the locking piece rod 22 to rotate in the opposite first rotation direction a, and make the locking piece torsion spring 23 generate a first torsion force, and the locking piece torsion spring 23 generates the first torsion force to make the locking piece rod 22 rotate in the first rotation direction a; when the ratchet 30 does not rotate in the second rotation direction B, the second torsion provided by the torsion spring 42 starts to rotate the ratchet 30 in the second rotation direction B, the locking member rod 22 rotates in the first rotation direction a, one of the valleys 313 of the ratchet 30 rotating in the second rotation direction B is locked with the locking piece 21, and further, when the locking piece 21 touches the plane 311 beside the valley 313, the locking piece 21 falls into the valley 313 and is locked in the valley 313, so that the locking piece 21 cannot continue to rotate in the first rotation direction a; in addition, the plane 311 touching the fastening piece 21 will also abut against the inclined surface 211 of the fastening piece 21, and will be resisted by the inclined surface 211 of the fastening piece 21 fastened to the valley 313, so that the ratchet 30 cannot rotate continuously along the second rotation direction B, and thus, the fastening piece 21 and the ratchet 30 are fastened to the valley 313.
In an embodiment of the present invention, as shown in fig. 3, 6 to 8, the unlocking member 50 is used to unlock the locking between the locking piece 21 of the locking member 20 and the ratchet 30. The unlocking member 50 includes a pressing portion 51, a push rod 52, a connecting rod 53 and an elastic body 54. The pressing portion 51 is a button disposed on the housing 110 and exposed to the outside, so that the user can press the button to move the pressing portion 51 along a pushing direction C. The push rod 52 is connected to the pressing portion 51 and touches the card-fixing piece 21. When the push rod 52 is driven by the pressing portion 51 to move along the pushing direction C, the push rod 52 pushes the locking piece 21, and the push rod 52 drives the locking piece 21 to move away from the ratchet 30, so that the locking piece 21 is separated from the valley 313 and released from the ratchet 30. The connecting rod 53 is connected to the pressing portion 51. The elastic body 54 is, for example, a spring, and the elastic body 54 connects the connecting rod 53 and the inner housing 112. The elastic body 54 is used to provide an elastic force to the connecting rod 53 to drive the connecting rod 53 to move along the direction opposite to the pushing direction C.
The user can operate the supporting structure 1 of the present invention to open or close the supporting structure 1 relative to the housing 110, so that the electronic device 100 is generally in an L-shaped upright embodiment or in a tablet computer embodiment. When a user needs to use the supporting structure 1 of the present invention to support the electronic device 100, as shown in fig. 1 and fig. 2, the user can apply a force to the supporting member 10 by hand, so that the housing 110 rotates along the direction opposite to the rotating direction X with respect to the supporting member 10 to open up to an angle. As shown in fig. 1 and 3 to 5, during the process that the housing 110 rotates relative to the support 10 and rotates along the direction opposite to the rotating direction X to open to the angle, the rotating shaft 40 and the ratchet 30 connected to the rotating shaft 40 rotate together through the connection between the support 10 and the rotating shaft 40, so that the ratchet 30 rotates relative to the locking member 20 along the direction opposite to the second rotating direction B. During the rotation of the ratchet 30 relative to the engaging member 20 in the direction opposite to the second rotation direction B, the engaging piece 21 slides upwards along the arc-shaped outer surface of the arc-shaped surface 312, i.e. towards the tooth crest 314; when the locking piece 21 slides along the arc-shaped outer surface of the arc-shaped surface 312 to pass over the crest 314, the locking piece 21 is influenced by the torsion of the locking piece torsion spring 23 to rotate along the first rotation direction a and fall into the adjacent valleys 313, and then the locking piece 21 continues to slide along the arc-shaped outer surface of the adjacent arc-shaped surface 312, so that the locking piece 21 moves in a reciprocating manner along the sawtooth-shaped moving surfaces of the valleys 313 and the crests 314; that is, the arc-shaped outer surface of the arc-shaped surface 312 is designed to allow the ratchet 30 to smoothly rotate along the direction opposite to the second rotation direction B relative to the fastener 20, and during the rotation of the ratchet 30, the fastener 21 is not blocked by the flat surface 311 to cause the ratchet 30 and the fastener 20 to be locked with each other. In this way, the user can smoothly rotate the housing 110 to a specific angle along the opposite direction of the rotation direction X according to personal requirements.
When the user rotates the housing 110 in the opposite direction of the rotation direction X by a specific angle, the user may stop applying a force to the supporting member 10, and at this time, if the fastening piece 21 is just located in one of the valleys 313, the fastening piece torsion spring 23 provides a first torsion force to drive the fastening piece rod 22 to rotate in the first rotation direction a, so that the fastening piece 21 sinks into the one of the valleys 313, and the fastening piece 21 cannot continuously slide along the adjacent arc surface 312; on the other hand, the inclined surface 211 of the locking piece 21 located in one of the valleys 313 is also attached to the plane 311 beside the valley 313, so that the plane 311 touching the inclined surface 211 of the locking piece 21 is resisted by the inclined surface 211 of the locking piece 21 locked in the valley 313, and the ratchet 30 cannot rotate continuously along the second rotation direction B, and thus, the locking piece 21 of the locking piece 20 is locked with the valley 313 of the ratchet 30. In addition, if the user stops applying force to the supporting member 10 and the fastening piece 21 is just located on the arc-shaped outer surface of the arc-shaped surface 312, the rotating shaft torsion spring 42 drives the shaft body 41 and the ratchet wheel 30 to rotate together along the second rotating direction B, so that the fastening piece 21 relatively moves to the valley 313 beside the arc-shaped surface 312 along the arc-shaped surface 312, and the fastening piece 21 of the fastening member 20 is fastened with the valley 313 of the ratchet wheel 30. By the clamping between the clamping member 20 and the ratchet 30, the housing 110 cannot rotate continuously in the opposite direction of the rotation direction X, so that the included angle between the supporting member 10 and the housing 110 can be kept fixed; thereby, the user can use the support 10 as a base to erect the housing 110, so that the electronic device 100 as a whole presents an L-shaped erect embodiment for the user to watch the screen 120.
When the user needs to change the upright electronic device 100, which is L-shaped as a whole, to the tablet pc, as shown in fig. 2, 6 to 8, the user can press the pressing portion 51 disposed on the housing 110 with a finger to move the pressing portion 51 along the pushing direction C. When the push rod 52 is driven by the pressing portion 51 to move along the pushing direction C, the push rod 52 pushes the locking piece 21, and the push rod 52 drives the locking piece 21 to move away from the ratchet 30, so that the locking piece 21 is separated from the valley 313 and released from the ratchet 30. At this time, the user can apply a force to the supporting member 10 or the housing 110 to close the supporting member 10 and the housing 110, so that the electronic device 100 is implemented as a tablet computer. When the electronic device 100 is implemented as a tablet computer, the user does not need to press the pressing portion 51 with fingers; when the pressing portion 51 no longer receives the force applied by the user, the elastic force provided by the elastic body 54 to the connecting rod 53 drives the connecting rod 53 to move along the direction opposite to the pushing direction C, so that the locking piece 21 contacts with the ratchet 30 again, so that when the user rotates the housing 110 along the direction opposite to the rotating direction X and opens relative to the supporting member 10, the ratchet 30 can be locked with the locking pieces 20 at any time.
Through the design of the electronic device 100 and the supporting structure 1 thereof of the present invention, the support 10 can stably support the housing 110 by the fastening between the ratchet 31 of the ratchet 30 and the fastening piece 21 of the fastening piece 20. Since the ratchet 30 and the locking member 20 are locked to each other by a hardware structure, not by a friction force in the prior art, the overall size of the supporting structure 1 can be designed to be relatively small and not excessively occupy the space of the electronic device 100, and a user can easily operate the supporting structure 1 without applying too much force, so that the supporting structure 1 rotates relative to the housing 110 to open to stably support the housing 110, or rotates relative to the housing 110 to close to make the electronic device 100 present an implementation manner of a tablet computer.
It should be noted that the above-mentioned embodiments are only examples, and are not limited to the examples. For example, those skilled in the art will recognize that the invention may be practiced without these specific details.
