Description

TECHNICAL FIELD

[0001] The utility model relates to a pivot device, in particular to a pivot device with translation function. BACKGROUND

[0002] A pivot device is a rotating mechanism element widely used in daily life and electronic product field. Generally speaking, the pivot device includes a first rotating member and a second rotating member coaxially pivoted, which are respectively connected to an upper cover and a base of an electronic product, such as a notebook computer, so that the upper cover can be rotated relative to the base. In order to support the weight of the upper cover and the base and reduce the required force when opening and closing, the pivot device usually further includes a torsion element to provide the required torsion force during opening and closing.

[0003] When the pivot device is assembled, the two brackets pivoted coaxially are respectively connected between the protruding parts of the upper cover and the base, that is, the position of the connection between the upper cover and the base is fixed and cannot be changed with the angle of the upper cover being lifted. For example, after the upper cover of the electronic product is rotated relative to the base and opened by the pivot device, the upper cover will touch the protruding part of the base and interfere, and the upper cover cannot be opened to the preset maximum lifting angle. Therefore, the solution in the related art is to increase the structural distance (gap) between the protruding parts of the upper cover and the base. This undoubtedly causes the display screen to be pulled away from the relative state when in use, and the structural distance also causes defects in vision and is not conducive to the aesthetics of the electronic product.

[0004] Therefore, how to install the pivot device and reduce the structural distance between the protruding parts of the upper cover and the base without causing interference when lifting becomes a technical problem to be solved. SUMMARY

[0005] The utility model mainly aims at providing a pivot device with translation function, which is installed between an upper cover and a base of an electronic product, such as a notebook computer.

Throughout the drawings, the same elements are represented by the same or similar reference numerals. When the conventional structures or configurations may cause confusion in understanding the present application, they will be omitted.

[0108] As shown in Figures 1 to 5 , the hinge with translation function comprises a translation module 1 and a rotation module 2.

[0109] Please refer to Figure 2a and Figure 2b , the translation module 1 comprises a base 11 and a slider 12. The base 11 is a rectangular sheet body, which comprises a first accommodating hole 111 with an internal gear rack 112 radially arranged in a central portion, and at least one through slot 113 arranged on the left and right side walls of the base 11 respectively, which are used for existing locking members, such as screws, to be locked in the base 61 of an electronic product 6 (shown in Figure 5 and Figure 11 ), such as a notebook computer. Furthermore, the front wall and the rear wall of the base 11 are respectively provided with a guide rail 114 and a guide column 115 of a sliding rail mechanism, and the guide column 115 is connected between a pair of lugs 116 on both sides of the rear wall.

[0110] The slider 12 is a rectangular block, which is arranged on the base 11 and includes a second accommodating hole 121 in the form of an inverted chevron shape radially formed in a central portion, and a helical gear 122 arranged in the second accommodating hole 121. The helical gear 122 is connected to a spur gear 123 arranged in the first accommodating hole 111 and engaged with the internal gear rack 112. The bottom of the helical gear 122 extends a connecting tenon 122a in the form of a non-circular section, such as an oblong shape. The spur gear 123 is provided with a tenon groove 123a corresponding to the connecting tenon 122a. A connecting member 124, such as a screw, is screwed to the connecting tenon 122a to prevent the spur gear 123 from being separated from the bottom of the helical gear 122.

[0111] Furthermore, the slider 12 is provided with a rail groove 125 and a column groove 126 corresponding to the positions of the guide rail 114 and the guide column 115. The guide rail 114 is arranged in the rail groove 125, and the guide column 115 is arranged in the column groove 126, so that the slider 12 can slide transversely above the base 11. Therefore, when the helical gear 122 is rotated by the rotating module 2, the helical gear 122 synchronously drives the spur gear 123 to rotate and move transversely along the internal gear rack 112, so as to promote the transverse translation of the slider 12 above the base 11.

[0112] In addition, in order to avoid the problem of shaking of the slider 12 during the translation of the base 11, that is, to reduce the gap between the rail groove 125 and the guide rail 114, an arc-shaped elastic piece 127 is arranged in the rail groove 125. One end of the arc-shaped elastic piece 127 vertically extends a plug tenon 127a, and the rail groove 125 is provided with a tenon hole 125a (shown in Figure 8 and Figure 8a ) corresponding to the plug tenon 127a for insertion and positioning, so as to solve the shaking problem.

[0113] Furthermore, in order to provide the connection and positioning of the slider 12 and the rotating module 2, a first fixing member 128 and a second fixing member 129 are respectively arranged on the rear wall and the front wall of the slider 12. The first fixing member 128 and the second fixing member 129 are respectively screwed to the predetermined positions of the slider 12 by a connecting member 120, such as a screw.

[0114] As Figure 3As shown, the rotating module 2 comprises a shaft base 21, a driving shaft 22, and a driven shaft 23. The shaft base 21 is provided with a first shaft hole 211 and a second shaft hole 212 on the front side and the rear side respectively, and a recess 213 is arranged between the first shaft hole 211 and the second shaft hole 212. A spur gear 24 is pivotally connected in the recess 213. The spur gear 24 is provided with a front oblique rack 241 and a rear oblique rack 242 on the two end edges respectively. A top cover 25 is arranged to close the recess 213 so as to avoid the spur gear 24 from being separated from the recess 213. The top surface and the bottom surface of the spur gear 24 are provided with a pair of shaft pins 243. The recess 213 and the top cover 25 are provided with a bottom shaft hole 213a and a top shaft hole 251 respectively corresponding to the shaft pins 243. The spur gear 24 is pivotally connected between the recess 213 and the top cover 25, and can swing in the clockwise direction or the counterclockwise direction.

[0115] In addition, the top cover 25 is connected to the connecting hole 214 arranged around the recess 213 by at least one connecting member 252, such as a screw, penetrating through the corresponding cover hole 253.

[0116] Further, the right side of the second shaft hole 212 is provided with a shaft tube 215 connected thereto, and the outer circumferential surface of the shaft tube 215 is provided with a helical driven gear 216 engaged with the helical gear 122. One embodiment of the shaft tube 215 is integrally extended from the right side of the second shaft hole 212. Another embodiment of the shaft tube 215 is connected to the second shaft hole 212 by a connecting mechanism, such as at least one recess 217 embedded in the outer circumferential surface of the second shaft hole 212 corresponding to the tenon 218 arranged in a corresponding manner, so that the shaft tube 215 can rotate synchronously with the shaft base 21.

[0117] The driving shaft 22 comprises a first shaft rod 221 penetrating through the first shaft hole 211. The first shaft rod 221 is provided with a connecting plate 222 at one end, and the connecting plate 222 is provided with at least one connecting hole 223. The connecting member, such as a screw (not shown), penetrates through the connecting hole 223 and is locked to the upper cover 62 (shown in Figure 5 and Figure 11 ) of the electronic product 6, such as a notebook computer, by using the existing connecting member. In addition, the first shaft rod 221 is provided with a helical driving gear 224 engaged with the front oblique rack 241. Furthermore, in order to define the rotation angle of the driving shaft 22, the first shaft rod 221 is adjacent to a stopper 225 with a long circular cross section at the left side of the driving gear 224, and a pair of wedge-shaped stoppers 211a is protruded in a corresponding manner in the first shaft hole 211 corresponding to the position of the stopper 225. Figure 9 When the electronic product is in the closed state without operation, the pair of diagonal ends of the stopper 225 abut against a first side of the pair of wedge-shaped stoppers 211a.

[0118] The second shaft rod 231 is connected to the slider 12 by a fixing mechanism at one end thereof. The fixing mechanism includes a positioning tongue 232 provided at the right end of the second shaft rod 231, which is inserted into a positioning slot 128a of the first fixing member 128; and a connecting member 233, such as a screw, which is inserted through a hole 234 of the second shaft rod 231 and is connected to a fixing hole 121a of the slider 12, so that the right end of the second shaft rod 231 is fixed to the slider 12. The shaft tube 215 is disposed in a tube slot 129a of the second fixing member 129, and the driven gear 216 is adjacent to a stop ring 235 provided on the outer circumferential surface of the second shaft rod 231, so that the driven shaft 23 is fixed to the slider 12 and does not rotate.

[0119] Furthermore, the second shaft rod 231 is provided with a helical fixing gear 236 corresponding to the position of the rear inclined rack 242 in the second shaft hole 212, which is engaged with the rear inclined rack 242.

[0120] Furthermore, the pivot further includes two torsion units 3, each of which is connected to the first shaft rod 221 and the second shaft rod 231 on the left side of the shaft seat 21. Each torsion unit 3 includes at least one friction pad 31 through which the first shaft rod 221 and the second shaft rod 231 are connected, an elastic element 32 through which the first shaft rod 221 and the second shaft rod 231 are connected, and a tightening member 33, such as a non-slip nut, through which the first shaft rod 221 and the second shaft rod 231 are connected, thereby facilitating the adjustment of the torsion value of the driving shaft 22 and the driven shaft 23.

[0121] Please also refer to Figure 3 The elastic element 32 is selected from a plurality of disc-shaped elastic pieces, but is not limited thereto. In other embodiments, the elastic element 32 can be selected from a spring or a plurality of wave-shaped elastic pieces. Therefore, the first shaft rod 221 and the second shaft rod 231 are respectively affected by the elastic force of each elastic element 32 during rotation, so as to form axial torsion changes and generate stalling and positioning effects.

[0122] Furthermore, the first shaft 221 and the second shaft 231 each further include a torque assist unit 4 between the slide 2 and the torque unit 3. The torque assist unit 4 includes at least one auxiliary plate 41 and at least two friction washers 42. A first hole 411 and a second hole 412 are respectively defined at the ends of each auxiliary plate 41, corresponding to the positions of the first shaft 221 and the second shaft 231, for the first shaft 221 and the second shaft 231 to pass through. Furthermore, adjacent surfaces of the first hole 411 and the second hole 412 are each provided with a friction washer 42 for the first shaft 221 and the second shaft 231 to pass through and engage with. This increases the overall friction of the first shaft 221 and the second shaft 231 to compensate for the torque required for the rotation of the driving shaft 22 and the driven shaft 23.

[0123] like Figure 3 As shown, the torque assist unit 4 comprises three auxiliary plates 41. A friction washer 42 is disposed between each of two adjacent auxiliary plates 41, for the first shaft 221 and the second shaft 231 to pass through. Furthermore, the auxiliary plates 41 adjacent to the shaft seat 21 also comprise a friction washer 42 for the first shaft 221 and the second shaft 231 to pass through. Furthermore, an auxiliary plate 41 adjacent to the torque unit 3 comprises a friction washer 42 for the first shaft 221 and the second shaft 231 to pass through. Therefore, the arrangement of these auxiliary plates 41 and friction washers 42 achieves the aforementioned effect of compensating for the torque required for the rotation of the driving shaft 22 and the driven shaft 23.

[0124] In addition, the shaft seat 21, the driving shaft 22, the driven shaft 23, the torque units 3 and the torque auxiliary unit 4 are further covered by a shield 5, leaving only the shaft tube 215, the fixing mechanism of the driven shaft 23 and the connecting piece 222 of the driving shaft 22 exposed on the right side of the shield 5, so as to form a Figure 1 The three-dimensional form shown.

[0125] Please refer to Figure 1 , which shows that the translation module 1 forms a first component after being assembled, and the rotation module 2, the torque units 3, the torque auxiliary unit 4 and the shield 5 form a second component after being assembled. Figure 4 A three-dimensional view of a hinge is shown (the shield 5 has been deleted for ease of observation).

[0126] and Figure 4 The hub shown can be installed on Figure 5 The electronic product 6 shown, for example, has the base 11 of the translation module 1 locked in the base 61 of the electronic product 6, such as a notebook computer; and the connecting piece 222 of the driving shaft 22 is locked to the upper cover 62 of the notebook computer. In particular, Figure 5The electronic product 6 is shown in a closed state of non-operation. That is, the angle of the driving shaft 22 relative to the translation module 1 is 0 degree.

[0127] Please refer to Figure 6 , which shows a bottom view of the hinge assembly in a closed state of non-operation. From the figure, it can be clearly observed that the spur gear 123 is engaged in a first position of the internal gear rack 112, so that the slider 12 is located at a first side of the base 11 through the slide rail mechanism.

[0128] Please refer to Figure 8 , which shows a transverse sectional view of the hinge in a closed state of non-operation. From the figure, it can be clearly observed that the driving gear 224 of the driving shaft 22 is engaged with the front inclined gear rack 241 on one side of the spur gear 24 pivotally connected to the shaft seat 21, while the opposite side of the rear inclined gear rack 242 is engaged with the fixed gear 236; and the lateral driven gear 216 of the shaft seat 21 is engaged with the helical gear 122 of the slider 12.

[0129] Please refer to Figure 8 , which shows a sectional view of the translation module. From the figure, it can be clearly observed that the spur gear 123 connected with the helical gear 122 is engaged in the first position of the internal gear rack 112 of the base 11, so that the slider 12 is located at the first side of the base 11 through the slide rail mechanism. And Figure 8a , which shows that the tenon 127a of the arc-shaped elastic piece 127 is inserted into the mortise hole 125a in the rail groove 125, so that the arc-shaped elastic piece 127 can elastically contact with the guide rail 114 to reduce the gap between the rail groove 125 and the guide rail 114 and solve the problem of shaking.

[0130] Please refer to Figure 9 , which shows that the pair of opposite diagonal ends of the stopper 225 of the driving shaft 22 respectively abut against a first side of the pair of wedge-shaped stop blocks 211a of the first shaft hole 211, serving as a closed angle stop mode.

[0131] Please refer to Figures 10 to 14 , in order to use the electronic product 6, the user only needs to hold the upper cover 62 with hand and open it to an angle (shown in Figure 11 ) in the rear direction (clockwise direction), so that the driving shaft 22 rotates synchronously. At this time, the second shaft hole 212 of the shaft seat 21 takes the fixed state driven shaft 23 as a fulcrum and rotates in the clockwise direction, so that the driven gear 216 of the shaft seat 21 drives the helical gear 122 to rotate, so as to make the spur gear 123 move along the internal gear rack 112 and move away from the first position, thereby allowing the slider 12 to translate forward on the base 11 through the slide rail mechanism.

[0132] Meanwhile, the driving shaft 22 located in the first shaft hole 211 rotates clockwise around the driven shaft 23 as a fulcrum to lift upward, so that the driving gear 224 of the first shaft rod 221 rotates clockwise to drive the front and rear oblique racks 241 and 242 of the spur gear 24 to rotate clockwise, thereby promoting the driving shaft 22 to further rotate clockwise until the hinge reaches the maximum opening angle as shown in the perspective view of Figure 10 , and Figure 13 , which shows the transverse sectional view of the hinge at the maximum opening angle. Figure 10 , which shows the transverse sectional view of the hinge at the maximum opening angle.

[0133] Please refer to Figure 12 , which shows the bottom view of the hinge at the maximum opening angle, from which it can be clearly observed that the spur gear 123 is engaged with a second position of the internal rack 112, so that the slider 12 is translated by the slide rail mechanism from the first side of the base 11 to a second side, that is, the slider 12 is translated by the slide rail mechanism forward on the base 11.

[0134] Please refer to Figure 14 , which shows that the opposite diagonal ends of the stopper 225 of the driving shaft 22 abut against a second side of the pair of wedge-shaped stoppers 211a of the first shaft hole 211, serving as the maximum opening angle stopper mode.

[0135] If the user does not intend to use the electronic product 6, only the upper cover 62 is closed forward (counterclockwise), so that the driving shaft 22, the spur gear 24, the shaft seat 21 and the driven gear 216 thereof, the helical gear 122 are reversely operated to allow the spur gear 123 to reversely translate from the second position of the internal rack 112 to the first position, and to promote the slider 12 to synchronously translate backward on the base 11 by the slide rail mechanism until the upper cover 62 of the electronic product 6 is closed with the base 61.

[0136] Therefore, through the implementation of the present application, the translation module and the rotation module are two independent module designs, which have the effects of convenient assembly, disassembly and testing. Furthermore, when the hinge is operated, the rotation module drives the slider in the translation module to form the translation movement on the base, which overcomes the interference phenomenon of the prior art and can reduce the structural spacing between the upper cover and the base. Furthermore, the limiting structure, i.e. the stopper structure, of the hinge is arranged between the first shaft hole of the shaft seat and the stopper radially of the driving shaft to produce a better stable stop effect, thereby increasing the service life of the hinge, which is a great structure for similar products.

However, these embodiments are only for the purpose of illustration, and are not intended to limit the scope of the present application. Although each embodiment is described above, this does not mean that the measures in each embodiment cannot be used advantageously in combination. The scope of the present application is defined by the appended claims and their equivalents. Without departing from the scope of the present application, those skilled in the art can make various substitutions and modifications, and these substitutions and modifications should all fall within the scope of the present application.
