To understand the concrete meaning of above-mentioned term as the case may be.
With reference to following description and drawings, it will be clear that these and other aspects of the embodiment of the present invention.In these descriptions
In attached drawing, some particular implementations in the embodiment of the present invention are specifically disclosed, to indicate to implement the implementation of the present invention
Some modes of the principle of example, but it is to be understood that the scope of embodiments of the invention is not limited.On the contrary, the present invention
Embodiment includes all changes, modification and the equivalent fallen within the scope of the spirit and intension of attached claims.
As shown in Figure 1, a kind of limit rotary shaft that one embodiment of the invention provides, including support base 1, positioning supporting block 5
With shaft slider plate 7, the support base 1 is equipped with the guide-track groove 2 for placing shaft slider plate 7 and is supported for placement positioning
The locating piece slot position 3 of block 5.
As depicted in figs. 1 and 2, shaft slider plate 7 include arc-shaped plate and tablet, the shaft slider plate 7 it is arc-shaped
Plate can the sliding in guide-track groove 2.End of the circular ring shape plate far from tablet of the shaft slider plate 7 is equipped with limit protrusion 8, institute
The block 4 having in support base 1 with the limit protrusion 8 to cooperation is stated, the limit of shaft is used for.It can adjust according to actual needs
The position of whole block 4, to realize the limit of different angle.
As shown in figures 1 and 3, positioning supporting block 5 is flexible metal derby, and the positioning supporting block 5 is arch knot
One end of structure, the positioning supporting block 5 is fixed in support base 1, and the other end is free end, and the free end is equipped with boss
6, the boss 6 contacts with shaft slider plate 7 and provides pressure.
As shown in Figure 1 to Figure 3, the inside of the arc-shaped plate of shaft slider plate 7 is equipped with securing channels 9, the securing channels 9
From one end of close tablet to one end far from tablet by deep and shallow variation, when the shaft slider plate 7 is slided along guide-track groove 2
When, the boss 6 positioned in supporting block 5 moves in the securing channels 9.The length of the securing channels 9, which exactly limits, to be turned
Axis from initial position be deployed into maximum angle during the distance streaked in shaft slider plate 7 of boss 6.
The limit rotary shaft that one embodiment of the invention provides further includes rotary shaft cover 10, the rotary shaft cover 10 and 1 phase of support base
Cooperation, fixed rotating shaft slider plate 7 and positioning supporting block 5.
The operation principle of the limit rotary shaft of one embodiment of the invention offer is described with reference to Fig. 4 and Fig. 5.
Such as the initial position that Fig. 4 is the limit rotary shaft that one embodiment of the invention provides, the at this time limit in shaft slider plate 7
Protrusion 8 guide-track groove 2 outermost end, position supporting block 5 on boss 6 be located at the most deep of the securing channels 9 in shaft slider plate 7
Place, the pressure provided is minimum, and 7 stress of shaft slider plate can be rotated at this time.As expanded angle increases, supporting block is positioned
The securing channels 9 that boss 6 on 5 contacts are more and more shallow, and the pressure provided is increasing, when shaft slider plate 7 no longer rotates,
Shaft slider plate 7 can be fixed on current location by the frictional force that the pressure provided by boss 6 generates.
If Fig. 5 is that the limit rotary shaft that one embodiment of the invention provides is deployed into maximum angle, the limit in shaft slider plate 7
Protrusion 8 touches the block 4 in support base 1, can not continue to be unfolded, and positions protrusion 6 and fixing groove in supporting block 5 at this time
The most shallow place contact squeeze in road 9, provides maximum pressure, reaches fixed effect.
Limit rotary shaft according to the present invention, boss and shaft slider plate contact and provide pressure, are slided using pressure countershaft
Block plate is fixed, and when shaft is unfolded from initial position, the securing channels of boss contact are by deep and shallow, and the pressure of acquisition is increasingly
Greatly, when shaft is deployed into maximum angle, limit protrusion is contacted with block, while boss contacts acquisition with the most shallow place of securing channels
Maximum pressure plays limit fixed effect, while in turn avoiding existing shaft and lead to the feelings of casing rupture because spring force is excessive
Condition.
The present invention also provides a kind of electronic device, including flip cover, fuselage main body and above-mentioned limit rotary shaft, the branch
Support pedestal 1 is fixed in fuselage main body, and the shaft slider plate 7 is fixed on flip cover.
