Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and examples.

Referring to fig. 1 to 3, a first embodiment of a front-back sliding hinge 10 of the present invention is adapted to be disposed between a first body 20 and a second body 30 to form an electronic device 100 together, where the electronic device 100 has two front-back sliding hinges 10 disposed symmetrically, and the electronic device 100 may be, for example, a foldable device or a handheld device such as a mobile phone, a tablet computer, and a notebook computer, in which the embodiment is described by taking a notebook computer as an example, the first body 20 is a portion where a keyboard is disposed, and the second body 30 is a portion where a screen is disposed. The front-rear sliding type hinge 10 includes a base 1, a movable table 2, and a pivot unit 3.

Referring to fig. 3 to 7, the base 1 includes a substantially n-shaped seat 11, a rack 12 extending along a front-back direction D1 below the seat 11, and a guide post 13 extending along the front-back direction D1 and penetrating the seat 11 and the movable stage 2. The base 11 forms a guiding slot 111 extending along the front-back direction D1 and has a first side 112 and a second side 113 spaced apart from the first side 112.

The movable platform 2 is movably disposed on the base 1 along the front-back direction D1, and includes a bottom plate 21, a first upright block 22a disposed on the bottom plate 21 for the rotation shaft unit 3 to pass through, and a second upright block 22b disposed on the bottom plate 21 for the rotation shaft unit 3 to pass through and spaced from the first upright block 22 a. One end of the bottom plate 21 forms a protruding rib 23 movably received in the guiding slot 111, and the other end is used for the guiding post 13 to pass through. The second upright block 22b forms two grooves 22b1 located at opposite ends from each other and having a slope.

The rotating shaft unit 3 comprises a rotating shaft 31 passing through the movable table 2 along a left-right direction D2 and having a passing portion 311, a movable gear 32 extending along a vertical direction D3 and rotatably passing through the movable table 2 and engaging with the rack 12, a first bevel gear 33a fixedly sleeved on the rotating shaft 31 and engaging with the movable gear 32, a second bevel gear 33b movably sleeved on the rotating shaft 31 and engaging with the movable gear 32, a connecting plate 34 fixedly connected to the rotating shaft 31 and connected to the second body 30, a first pad 35a fixedly sleeved on the penetrating portion 311, a second pad 35b fixedly sleeved on the penetrating portion 311 and spaced from the first pad 35a, a plurality of torque plates 36 sleeved on the penetrating portion 311 and located between the first pad 35a and the second pad 35b, and a fixing member 37 fixedly locked to the end of the rotating shaft 31 and abutted to the second pad 35 b. The through portion 311 of the rotating shaft 31 can allow the first bevel gear 33a to be sleeved and pass through the first upright block 22a and the second upright block 22b, and the rotating shaft 31 further has an abutting disc portion 312 abutting against the first upright block 22a, a joint portion 313 connected to the abutting disc portion 312, and a screw lock portion 314 connected to the end of the through portion 311. The movable gear 32 has a bevel gear portion 321 engaged with the first bevel gear 33a and the second bevel gear 33b, a connecting portion 322 connected to the bevel gear portion 321 and penetrating the movable stage 2, and a spur gear portion 323 connected to the penetrating portion 311 and engaged with the rack 12. The movable gear member 32, the first bevel gear member 33a and the second bevel gear member 33b are all located between the first upright block 22a and the second upright block 22b, and the first bevel gear member 33a and the second bevel gear member 33b abut against the first upright block 22a and the second upright block 22b, respectively. The friction force generated when the rotating shaft 31 drives the first pad 35a and the second pad 35b to rotate relative to the torque plate 36 can provide the torque force required by the operation of the front and rear sliding hinge 10 of the present invention, but the torque force is not limited to this type. The first gasket 35a forms two projections 35a1 located at opposite ends from each other. The fixing member 37 is a nut screwed to the screw part 314 to position the first gasket 35a, the second gasket 35b and the torque plate 36, prevent the first gasket 35a, the second gasket 35b and the torque plate 36 from being deviated in the left-right direction D2 and ensure close abutment therebetween. By engaging the first bevel gear part 33a, the movable gear part 32 and the second bevel gear part 33b with each other, the gears are stable, and the first bevel gear part 33a is prevented from being displaced along the length direction of the rotating shaft part 31 because the positions can be restricted from each other.

Referring to fig. 3, 8 to 10, when a user wants to use the electronic device 100 and needs to separate and unfold the first body 20 and the second body 30, the connecting plate 34 drives the rotating shaft 31 to rotate, so that the first bevel gear 33a synchronously rotates, and drives the movable gear 32 to rotate because the first bevel gear 33a is engaged with the bevel gear portion 321 of the movable gear 32, and finally the movable gear 32 rotates and drives the second bevel gear 33b to rotate, and the spur gear 323 is engaged with the rack 12, so that the movable gear 32 can drive the movable stage 2 and the rotating shaft 31 to move between a first position and a second position along the rack 12. In the first position, the shaft unit 3 is close to the first side portion 112, the movable platform 2 abuts against the first side portion 112, the distance between the shaft unit 3 and the rear edge of the first body 20 is the first distance d1, the first body 20 and the second body 30 are in a folded state of abutting against each other, and the protrusion 35a1 is correspondingly accommodated in the groove 22b1 to serve as an auxiliary locking function. In the second position, the rotating shaft unit 3 is close to the second side portion 113, the movable platform 2 abuts against the second side portion 113, the distance between the rotating shaft unit 3 and the rear edge of the first body 20 is a second distance d2, at this time, the second body 30 is unfolded relative to the first body 20 to form an included angle therebetween in an unfolded state, and the protrusion 35a1 is separated from the groove 22b1 due to the first pad 35a being driven by the rotating shaft 31 to rotate relative to the second upright block 22 b. In the process of moving from the first position to the second position, the hinge unit 3 moves a distance in the front-back direction D1 such that the hinge unit 3 is relatively far away from the rear edge of the first body 20, and therefore the first distance D1 is smaller than the second distance D2, thereby achieving the purpose of enabling the hinge unit 3 to move toward the user when the electronic device 100 is turned on. It should be noted that, in the process of moving from the first position to the second position, if a certain external force is required to separate and unfold the first body 20 and the second body 30, a certain external force is required to resist the torsion, so that the protrusion 35a1 is correspondingly accommodated in the groove 22b1 and then does not leave the groove 22b1, thereby forming an auxiliary locking function. In the process of moving from the second position to the first position, since the groove 22b1 has an inclined surface, the protrusion 35a1 will slowly slide into the groove 22b1, and the torque will be gradually released, so that the first body 20 and the second body 30 will be automatically closed after a certain external force is applied, and no external force is continuously applied. And the hinge unit 3 can move toward the user when the electronic device 100 is turned on.

Referring to fig. 11 and 12, a second embodiment of the front and rear sliding hinge 10 'of the present invention is substantially the same as the first embodiment, except that the shaft unit 3 includes a sleeve member 38 movably sleeved on the shaft member 31 to replace the second bevel gear member 33b of the first embodiment, and the first bevel gear member 33a' has a slightly different shape. The sleeve member 38 abuts against the second upright block 22b and the first bevel gear member 33a ', respectively, preventing the first bevel gear member 33a' from being displaced along the length of the shaft member 31. By means of the sleeve member 38, the idle torque is reduced, and the gap between the first bevel gear member 33a ' and the movable gear member 32 is reduced due to the reduction of the second bevel gear member 33b, so that the first bevel gear member 33a ' can drive the movable gear member 32 correctly only by ensuring the accurate processing of the first bevel gear member 33a ' and the movable gear member 32, and the idle torque can be improved.

As described above, when the front-rear sliding hinge 10 of the present invention is rotated by the rotating shaft 31 of the rotating shaft unit 3, the first bevel gears 33a, 33a 'can be synchronously rotated, and the first bevel gears 33a, 33a' are engaged with the bevel gear portion 321 of the movable gear 32 to rotate the movable gear 32, and the spur gear 323 is engaged with the rack gear 12 to allow the movable gear 32 to drive the movable table 2 and the rotating shaft 31 along the rack gear 12 to move in the front-rear direction D1, so that the object of the present invention can be achieved.

It should be understood that the above description is only exemplary of the present invention, and that the scope of the present invention should not be limited thereby, and that the utility model is intended to cover all modifications and equivalents of the claims and their equivalents.
