Detailed Description

In order that the objects, technical solutions and advantages of the present invention will become more apparent, the present invention will be further described in detail with reference to the accompanying drawings in conjunction with the following specific embodiments.

Referring to fig. 1 to 7, the sliding locking device of the present disclosure includes a first connecting member 1, a first engaging wheel 2, a second engaging wheel 3, a sliding member 4, a second connecting member 5, and at least one collar 6.

As shown in fig. 1 and 2, the first connecting member 1 and the second connecting member 5 are disposed at an interval and oppositely provided with a pair of

upper shaft holes

11, 51, a pair of

lower shaft holes

12, 52 and a pair of long chutes 13 (shown in fig. 2), 53). Two sides of the sliding member 4 are respectively provided with a sliding tenon 41 in an axial direction, wherein one sliding tenon 41 is sleeved in the adjacent sliding slot 13, the other sliding tenon 41 is sleeved in the adjacent sliding slot 53, and the top and the bottom of the sliding member 4 are respectively provided with an upper arc surface 42 and a lower arc surface 43.

The first engaging wheel 2 is axially provided with a non-circular first through hole 21 and a first concave portion 22 on an outer circumferential surface, and the second engaging wheel 3 is also axially provided with a non-circular second through hole 31 and a second concave portion 32 on an outer circumferential surface.

During operation, the sliding member 4 can move along the pair of long

sliding slots

13, 53 to form a radial sliding movement, so that the upper arc surface 42 is buckled into the first concave portion 22 or the lower arc surface 43 is buckled into the second concave portion 32, i.e. the first engaging wheel 2 or the second engaging wheel 3 is locked and can not rotate.

The sliding locking device is technically characterized in that at least one lantern ring 6 made of high polymer elastic materials, such as rubber or silica gel, is sleeved on at least one sliding tenon 41. That is, as shown in fig. 4, a collar 6 is sleeved on the sliding tenon 41 adjacent to the first connecting member 1 (first embodiment). As shown in fig. 8, a collar 6 is fitted over the sliding tenon 41 adjacent to the second connecting member 5 (second embodiment). As shown in fig. 9, two sets of rings 6 are respectively sleeved on the sliding tenon 41 adjacent to the first connecting member 1 and the sliding tenon 41 adjacent to the second connecting member 5 (third embodiment).

The arrangement of the at least one sleeve ring 6 enables at least one side of the sliding member 4 to provide a buffering function to eliminate the dimension error problem in the prior art, and supports the sliding member 4 to avoid tilting between the first engaging wheel 2 and the second engaging wheel 3, thereby achieving the effect of stabilizing the sliding member 4, and facilitating the operation of double-shaft alternate turning, thereby avoiding the generation of false torque force caused by excessive friction force, and improving the noise generation. Furthermore, the sliding member 4 is manufactured by turning, and the problem of life reduction caused by friction between different materials can be reduced through the arrangement of the at least one sleeve ring 6.

In particular, referring to fig. 1 and 2 again, the first engaging wheel 2 and the second engaging wheel 3 of the sliding type locking device are respectively provided with a first stopper 14 and a second stopper 15 at the adjacent surface of the first connecting member 1. The first engaging wheel 2 has a first stop portion 23 corresponding to the first stop 14 for limiting the rotation stroke, for example, 180 degrees, and the second engaging wheel 3 has a second stop portion 33 corresponding to the second stop 15 for limiting the rotation stroke, for example, 180 degrees.

Referring to fig. 1 to 4, the sliding locking device is used for a dual-shaft hinge, which includes the sliding locking device, a first mandrel 7, a second mandrel 8, and two sets of torsion auxiliary adjusting units 10.

One end of the first spindle 7 axially extends through the upper through hole 51 of the second connecting member 5, the first through hole 21 of the first engaging wheel 2 and a first shaft 71 of the upper through hole 11 of the first connecting member 1, so that the first engaging wheel 2 and the first shaft 71 are linked, and the other end has a first fixing portion 72, wherein the first fixing portion 72 is fixed to an electronic device, such as a notebook computer, by using a conventional connecting member, such as a rivet, and is connected to a first support a of a screen.

The whole structure of the second mandrel 8 is the same as the first mandrel 7, so one end of the second mandrel 8 also axially extends through the lower through hole 52 of the second connecting member 5, the second through hole 31 of the second engaging wheel 3 and a second shaft 81 of the lower through hole 12 of the first connecting member 1, and the other end has a second fixing portion 82, and the second fixing portion 82 is fixed to the electronic device, such as a notebook computer, by using a conventional connecting member, such as a rivet, and is connected to a second support B of a main body.

The dual-axis hinge further includes a third connecting member 9, the third connecting member 9 is disposed between the second connecting member 5 and the first and

second mandrels

7 and 8, and is provided with an upper through hole 91 for the first shaft rod 71 to pass through and a lower through hole 92 for the second shaft rod 81 to pass through. Wherein a friction pad 93 is disposed between the second connecting member 5 and the third connecting member 9 and is coupled to the first spindle 7 and the second spindle 8, respectively, so as to increase the friction torque of the dual-axis hinge.

The first spindle 7 and the second spindle 8 are respectively connected with a torsion auxiliary adjusting unit 10, each torsion auxiliary adjusting unit 10 includes an elastic element 101 for the first shaft 71 and the second shaft 81 to respectively penetrate through, and a pressing member 102, such as an anti-slip nut, for the first shaft 71 and the second shaft 81 to respectively lock, thereby facilitating the micro adjustment of the torsion value of the

spindles

2, 3. As shown in fig. 1 and fig. 2, the elastic element 101 is selected from a plurality of disc-shaped elastic pieces, but not limited thereto, in other embodiments, the elastic element 101 may be selected from a spring or a plurality of wave-shaped elastic pieces. Therefore, the first spindle 7 and the second spindle 8 are respectively affected by the elastic force of each elastic element 101 during the alternate rotation to form the axial torque variation and generate the stagnation and positioning effect.

In addition, the friction pad 93 is disposed between the elastic element 101 and the pressing element 102 to prevent the pressing element 102 and the elastic element 101 from being worn due to direct friction, so that the torque is stably formed within a predetermined range. In another embodiment, however, the auxiliary torque adjusting unit 10 is an optional component, which can be selectively used according to the actual torque requirement.

Particularly, a locking cam 103 for the first shaft rod 71 and the second shaft rod 81 to penetrate and link is respectively disposed between the first connecting member 1 and the torsion auxiliary adjusting unit 10, and at least two protrusions 104 and at least two grooves 16 for the at least two protrusions 104 to be mutually embedded are oppositely disposed on the adjacent surface of each locking cam 103 and the first connecting member 1, so as to form the dual-shaft hinge device with rotation limiting and automatic locking functions.

A spacing ring 105 made of polymer elastic material is disposed between the locking cam 103 and the corresponding elastic element 101 for the first shaft rod 71 and the second shaft rod 81 to penetrate through respectively, so as to reduce the locking noise generated by the locking cam 103 during automatic locking.

As shown in fig. 3 to 5, they show the perspective view and the sectional view after assembling the sliding type locking device, the first spindle 7, the second spindle 8, and the two sets of torsion auxiliary adjusting units 10. If the first bracket a is attached to an electronic device, such as a screen of a notebook computer, and the second bracket B is attached to a body of the electronic device, such as a notebook computer. The first bracket a and the second bracket B are disposed in parallel to form a first angle, such as a 0 degree configuration, that is, when the first engaging wheel 2 and the second engaging wheel 3 are at 0 degree, the upper arc surface 42 of the sliding member 4 is buckled into the first concave portion 22 of the first engaging wheel 2, so that the first engaging wheel 2 cannot rotate but only the second engaging wheel 3 can rotate.

As shown in fig. 6, the second mandrel 8 is rotated clockwise to a second angle, for example, 180 degrees, so that an included angle of 180 degrees is formed between the first bracket a and the second bracket B; that is, the second engaging wheel 3 rotates 180 degrees clockwise relative to the first engaging wheel 2, and at this time, the second concave portion 32 rotates to a position below the lower arc surface 43, so that a gap is formed therebetween, and the first engaging wheel 2 is unlocked.

As shown in fig. 7, the first spindle 7 is rotated counterclockwise to a third angle, for example, 180 degrees, so that the first bracket a and the second bracket B have been rotated by 360 degrees; that is, the first engaging wheel 2 rotates 180 degrees counterclockwise (360 degrees relative to the second engaging wheel 3) to make the sliding member 4 pushed by the outer circumference of the first engaging wheel 3 to slide longitudinally and downwardly, so that the lower arc surface 43 of the sliding member 4 is buckled into the second concave portion 23 of the second engaging wheel 3, and the second engaging wheel 3 cannot rotate but only the first engaging wheel 2 rotates clockwise.

Therefore, through the descriptions of fig. 5 to 7, a dual-axis alternating-turning mode is formed, so that the included angle formed between the first support a and the second support B can be adjusted by the first spindle 7 and the second spindle 8 in an alternating-rotation manner during the alternating turning of the dual axes, so that the body of the electronic device is in a cover-closed state of 0 degree relative to the screen, or in a superposed state of being opened and rotated to 360 degrees, and the body and the screen are reversely and oppositely overlapped, thereby avoiding the situation that the two spindles are arbitrarily turned over, and reducing the situation that the telecommunication line is twisted or entangled.

Therefore, through the implementation of the present disclosure, at least one set of elastic polymer material, such as rubber or silicone, is sleeved on at least one of the tenons, so that at least one side of the sliding member provides a buffering function to eliminate the dimension error problem in the prior art, and the sliding member is supported to avoid tilting between the first engaging wheel and the second engaging wheel, so as to obtain the effect of stabilizing the sliding member. Moreover, a spacing ring made of high molecular elastic material is arranged between the locking cam and the corresponding elastic element, so that the locking noise generated by the locking cam during automatic locking can be reduced, and the locking cam can be an unprecedented good structure for the similar articles.

The disclosure is a preferred embodiment, and it is apparent that local changes or modifications can be made by those skilled in the art without departing from the scope of the patent rights of the disclosure.
