Synchronous motion device for double shaft system

The present invention relates to a synchronous motion device for a double-shaft system; in particular, a combination of a pivot application actuator, a reactor and a linkage, which transmits power in an operation-cooperating operation, so that the first and second axes are relatively A technical means of generating a synchronous rotation.

It can be mounted on electronic objects such as mobile phones, notebook computers, PDAs, digital video cameras, e-books, etc. by means of external pivots or shafts that can be reciprocally rotated to cover or display screens or viewing windows. It is rotatable and has an opening and closing function, which is a well-known technique. For example, Taiwan Patent No. 97222022 "Rotary Shaft Structure", No. 96217011 "Pivot Positioning Member", and No. 98207366 "Pivot Structure", etc., provide a typical embodiment.

In order to provide more operating modes and application ranges for display modules (eg, screens) and/or body modules of electronic objects, the prior art has also disclosed a method between a display module and a body module. The double shaft is arranged to enable the display module and/or the body module to generate different operating modes or rotation angles. For example, Taiwan No. 96148572 "Super Wide Angle Double Shaft Structure", No. 99211350 "Double Pivot Hub" patent case, etc., provides a feasible embodiment.

A subject related to the above embodiments in terms of operation, motion and structural design is that such a pivot or shaft assembly generally employs a plurality of spacers having through holes, concave and convex positioning portions, friction plates, springs, and the like on the rotating shaft; Both ends of the shaft are respectively fixed by buckles or fixing members. And, in conjunction with the energy accumulation and release of the spring, the rotation and positioning of the shaft or pivot assembly is achieved. Basically, the overall structural design and the assembly fit of the embodiment are relatively complicated; and the uneven positioning portion of the gasket and the friction plate is prone to wear and affect the positioning effect after the normal operation and cooperation.

Conventional techniques have also disclosed a combination of components such as a rotating wire and a linked wire (or belt) to transmit power or drive shaft motion. However, as is known to those skilled in the art, the combined structure of the wire or the drive belt may have a kinetic energy transfer delay during the cooperative operation. The reason for this is that there is a gap between the wire (or the belt) and the runner, resulting in an unsound situation of sliding or actuation; the wire (or belt) has elastic properties, the wire (or belt) and the fixed structure of the wheel combination are not Ideally, the traction pull phenomenon generated when the wire is loaded or transmitted is increased, and the displacement effect of the transmission is relatively reduced, or the wire is detached from the runner. In particular, after the wire or the belt is used for a period of time, the preset force during the original assembly is reduced due to the fatigue fatigue, and the synchronous motion of the transmission mechanism is relatively reduced.

In some applications, the wire or the belt is more susceptible to fatigue (or the process of moving the slider module), causing the wire or belt to fall off the wheel, and destroying the shaft. Synchronization bit of the device Move.

Another problem in the application and manufacture of the above-mentioned wire or transmission belt is that the wire or the transmission belt is required to be in a state of tension during the assembly work; this causes difficulty in quality control and can not be achieved when the wire is pulled and assembled. Better product yield and shorter assembly man-hours; in contrast, it also increases the manufacturing cost of the product.

In order to improve the above situation, the old method has also disclosed a technical structure in which a plurality of gears are used to transmit power to synchronize the rotation of the double shaft. However, as is known to those skilled in the art, the provision of a plurality of gear transmission structures on the double shaft cannot make the spacing of the double shafts as small as possible, which reflects that the entire transmission or structure needs to occupy a large space. Or volume. In particular, the transmission device is applied to a notebook computer or a small electronic device, which cannot meet the requirements of light and thin design; this situation is not what we would expect.

Typically, these references show the use and structural design of the shaft or its associated bonding components. If the redesign considers the structure of the shaft and related components, and the above application, it is different from the conventional one, it will change its use type, which is different from the old method; in essence, it will also increase its application range. And ease of assembly.

According to the above, the shaft or its related combination components are considered in the following aspects of structural design and operation technology:

1. Provide a synchronous motion device, which is installed between the display module and the body module; allows the operator to rotate the display module only 0°~180°, so that the body module is also relatively Simultaneous rotation of 0 ° ~ 180 °, so that the total rotation angle of the display module and the body module reaches 360 °; in the electronic equipment with more operating modes (or application range), easy to operate . At the same time, the synchronous motion effect and stability of the synchronous motion device and the rotating shaft in the operational cooperation are increased.

2. Considering the structural design of the synchronous motion device or the transmission mechanism, the conventional art application should be removed from the application of a plurality of spacers having a through hole, a concave and convex positioning portion, a friction plate, a spring, and the like in a rotating shaft; Cooperate with the energy accumulation and release of the spring to achieve the rotation and positioning of the shaft assembly. Therefore, the structure and assembly fit of the conventional art are complicated, and the uneven positioning portion of the gasket and the friction plate is easily worn, and the positioning effect is affected, and a significant improvement can be obtained.

3. The design provides a transmission mechanism and related mating structure different from the prior art to solve or overcome the situation that the kinetic energy transmission delay is generated by the conventional wire or the transmission belt; or the wire and the runner combination have a gap, and the sliding occurs during the operation of the cooperative operation. Or the action is not correct; or the fixed structure of the wire and the runner combination is not ideal, so that the pulling phenomenon of the wire load or the transmission of power is increased, and the transmission effect is reduced.

4. Considering the structural design of the synchronous motion device or the transmission mechanism, removing the technical structure of applying the plurality of gear transmission powers by the old method; and making the spacing of the double shafts to be reduced as much as possible to reduce the entire transmission device Or the space or volume of the structure; and, in line with the light and thin design requirements of the electronic device.

None of these topics have been specifically taught or disclosed in the above references.

Referring to Figures 1, 2 and 3, the synchronized motion device for the dual-axis system of the present invention comprises a first axis and a second axis; respectively, indicated by reference numerals 10 and 20. The first shaft 10 and the second shaft 20 are combined and disposed in a casing 55; the first and second shafts 10, 20 respectively have a fixed end 10a, 20a and a pivot end 10b, 20b. The fixed ends 10a and 20a are matched with a fixing base (not shown), and the first and second shafts 10 and 20 are respectively fixed to the display module 91 and the body module 92 of the electronic device 90 (for example, a mobile phone, a computer, etc.). .

Referring to Figures 2, 3 (or 4, 5), the synchronous motion device includes a pivoting end 10b of the first shaft 10 provided with an actuator 11; the actuator 11 is rotated with the first shaft 10. The pivoting end 20b of the second shaft 20 is provided with a reaction The reactor 22 is in a form in which the second shaft 20 rotates in synchronization. And, the pivoting ends 10b, 20b of the first and second shafts 10, 20 are provided with a linker 30 that connects the actuator 11 and the reactor 22. And, the actuator 11, the reactor 22, and the coupling 30 are combined with the fixing assembly 50 on the first shaft 10 and the second shaft 20. Therefore, when the first shaft 10 drives the actuator 11 to rotate, the linkage 30 is displaced, forcing the reactor 22 to rotate in the direction in which the opposite actuator 11 moves, and the first and second shafts 10, 20 are synchronized. The role.

In a preferred embodiment, the coupler 30 includes a first body 31 and a second body 32 that are combined on the first shaft 10 and the second shaft 20, respectively; and, the first body 31 and the second body 32 A form that is integrally formed or joined together to produce an (axial) displacement motion on the first shaft 10 and the second shaft 20.

Figures 4 and 5 depict that the first body 31 and the second body 32 define a main end 31a, 32a and a secondary end 31b, 32b, respectively. The main end 31a of the first body 31 is in contact with the actuator 11; the secondary end 31b of the first body 31 is in contact with a sub-actuator 12 disposed on the first pivotal end 10b. And, the main end 32a of the second body 32 is in contact with the reactor 22; the secondary end 32b of the second body 32 is in contact with a sub-reactor 23 disposed on the second shaft pivoting end 20b.

Therefore, when the first shaft 10 drives the actuator 11 to rotate, the linkage 30 is displaced on the first and second shafts 10, 20; and the secondary actuator 12 rotates in response to the rotation of the first shaft 10, a space to allow this The displacement movement of the interlock 30. When the actuator 30 generates a displacement motion, the main end 32a of the second body 32 pushes the reactor 22 to rotate in the direction in which the opposite actuator 11 (or the secondary actuator 12) moves, causing the second shaft 20 and the sub-reactor 23 to be generated. Synchronous rotation movement.

In detail, the actuator 11, the sub-actuator 12, the reactor 22, and the sub-reactor 23 are of a type similar to a reel having a shaft hole a for the actuator 11, the sub-actuator 12 and the reactor 22, respectively. The sub-reactors 23 are respectively fitted on the pivot ends 10b, 20b of the first and second shafts 10, 20. The cross-sectional shape of the axial hole a is identical to that of the first and second pivotal ends 10b, 20b. For example, the figure shows that the first and second pivotal ends 10b, 20b (or the shaft hole a) are in the shape of a rectangular cross section; the pivot hole a is pivotally connected to the first and second shafts 10, 20 Terminals 10b, 20b. Further, the ejector 11 and the sub-actuator 12 are rotated together with the first shaft 10; the reactor 20, the sub-reactor 23 and the second shaft 20 are rotated together.

In the illustrated embodiment, the actuator 11, the sub-actuator 12, the reactor 22, and the sub-reactor 23 each have a beveled edge b; corresponding to the beveled edge b, the first and second bodies 31 of the connector The main ends 31a, 32a and the sub-ends 31b, 32b of 32 also form an interactive ramp 31c, 32c, 31d, 32d structure. The beveled edges b (and the beveled faces 31c, 32c, 31d, 32d) form an included angle of 30° to 60° with a reference axis (for example, the axis of the first axis 10 or the second axis 20).

In a preferred embodiment, the angle of the angle is selected to be 45° to facilitate the actuator. 11. Operation and push fit between the sub-actuator 12, the reactor 22, the sub-reactor 23, and the interconnector 30 (or the first and second bodies 31, 32).

It should be noted that, with reference to the axis of the first shaft 10 or the second shaft 20, the oblique direction of the oblique side b of the actuator 11 is the same as the oblique direction of the main end inclined surface 31c of the first body 31, but is opposite to The inclined direction of the oblique side b of the reactor 22 and the inclined direction of the main end inclined surface 32c of the second body 32; the oblique direction of the oblique side b of the sub-actuator 12 is the same as the inclined direction of the auxiliary end inclined surface 31d of the first body 31, but The oblique direction of the oblique side b of the sub-reactor 23 and the inclined direction of the secondary end inclined surface 32d of the second body 32.

Please refer to Figure 1, 2 or 3, assuming that the display module 91 is closed on the body module 92; the angle of the angle is defined as 0°. Referring to FIGS. 6 and 7, when the operator opens the display module 91 and causes the first shaft 10 to drive the actuator 11 (or the sub-actuator 12) to rotate by 90°, the oblique side b of the actuator 11 pushes the coupling 30 ( Or the main end 31a) of the first body 31 is displaced to the left in the figure; and the sub-actuator 12 is rotated in response to the rotation of the first shaft 10, so that the slope 31d of the first body secondary end 31b is gradually and the secondary actuator 12 The beveled edges b are joined. In other words, the displacement of the sub-actuator 12 is allowed to allow the displacement movement of the coupler 30.

When the actuator 30 produces a displacement motion, the ramp 32c of the second body main end 32a pushes the bevel b of the reactor 22, forcing the reactor 22 to rotate in the direction of movement of the opposite actuator 11 (or the secondary actuator 12), The second shaft 20 and the secondary reactor 23 produce a synchronous rotational motion.

Therefore, FIGS. 6 and 7 show that when the operator opens the display module 91 to rotate the first shaft 10 by 90°, the actuator 11 and the sub-actuator 12 cooperate with the interlock 30 and the reactor 22 and the sub-reactor 23. The transmission also rotates the second shaft 20 and the body module 92 clockwise to a position of 90°; that is, the display module 91 and the body module 92 rotate a total of 180°.

Referring to Figures 8 and 9, the position of the body module 92 is rotated clockwise to 180° when the position of the display module 91 is rotated by 180°; that is, the display module 91 and the body module 92 are rotated together. 360° range.

That is to say, the synchronous motion device allows the user to operate the display module 91 to rotate by an angle or a range, and the rotation angle or the range of the rotation stroke can be obtained twice; and the operation is simple and convenient.

Referring to FIG. 10, in a modified embodiment (second embodiment), the actuator 11 and the reactor 22 are in the form of a convex portion which is respectively disposed at the pivot of the first shaft 10 and the second shaft 20. On the terminals 10b, 20b; and corresponding to the convex shape of the actuator 11 and the reactor 22, the first and second bodies 31, 32 are formed with the groove chambers 31g, 32g; the chambers 31g, 32g are at least partially A (spiral) guide groove 31e, 32e is formed in the region to accommodate the actuator 11 and the reactor 22; and the convex portion of the actuator 11, the reactor 22, and the guide grooves 31e, 32e are allowed to form a relative movement.

That is, when the first shaft 10 drives the actuator 11 to rotate, the guide groove 31e of the first body 31 is engaged, and the linkage 30 is pushed on the first and second shafts 10, 20 to guide the second body 32. Tank 32e pushes reactor 2 2 The rotation is generated such that the second shaft 20 produces a synchronous rotational movement in the direction of rotation of the opposite first shaft 10.

In the embodiment taken, the spiral direction of the guide groove 31e of the first body 31 is opposite to the spiral direction of the guide groove 32e of the second body 32.

Referring to FIG. 11, in a possible embodiment (third embodiment), the actuator 11 and the reactor 22 are in a threaded configuration, respectively disposed at the pivot ends of the first shaft 10 and the second shaft 20. 10b, 20b, forming a screw-like type; and corresponding to the thread type of the actuator 11 and the reactor 22, the first and second bodies 31, 32 are formed with the shape of the groove chambers 31g, 32g; the chamber 31g A screw groove 31f, 32f is formed in each of 32g to engage the actuator 11 and the reactor 22.

That is, when the first shaft 10 drives the actuator 11 to rotate, the threaded groove 31f of the first body 31 is engaged to push the relative displacement of the coupling 30 on the first and second shafts 10, 20. Accordingly, the threaded groove 32f of the second body 32 forces the reactor 22 to rotate, causing the second shaft 20 to produce a synchronous rotational movement in the direction of rotation of the opposite first shaft 10.

In a possible embodiment, in order to make the above-mentioned actuator 11 (and/or sub-actuator 12), the interlock 30 and the reactor 22 (and/or the sub-reactor 23) stable and reliable in the operation of the operation movement The synchronous motion device includes a set of frames 40, which cooperate with the fixing member 41 to lock the frame 40 into an integral shape; and are used for covering and accommodating the above-mentioned actuator 11 (and/or sub-actuator 12) and the interlocking device 30. And reactor 22 (and / or sub-reactor 23).

It can be appreciated that the transmission mating structure of the synchronous motion device causes the actuator 11 (and/or the secondary actuator 12) to cooperate with the linkage 30 and the reactor 22 (and/or the secondary reactor 23) during the transmission of power. The combined type, as in the case where the conventional technique produces a rotational torsion change or slip, is minimized as much as possible; and the rotation of the first and second axes 10, 20 obtains a smooth motion. Further, when the rotational operation force of the person disappears, the rotation is stopped to form a positioning action.

Referring to Figures 12, 13 and 14, a further possible embodiment (fourth embodiment) of the present invention for synchronizing motion devices for a dual spindle system is depicted. The oblique side b of the ejector 11 and the oblique side b of the sub-exciter 12 respectively include a first oblique side b1 and a second oblique side b2; and the ejector 11 and the sub-exciter 12 have a column in the axial direction c and the shaft hole a formed in the column c, when the ejector 11 and the sub-actuator 12 are fitted to the first shaft 10 via the shaft hole a, the first oblique side b1 of the ejector 11 contacts the auxiliary actuator 12 The first oblique side b1 (the column c of the ejector 11 also forms a contact pattern with the column c of the secondary ejector 12); the second oblique side b2 of the ejector 11 and the second oblique side b2 of the secondary ejector 12 are defined together A (spiral) priming track 13 is produced.

It should be noted that the first oblique side b1 and the second oblique side b2 and a reference axis (for example, the axis of the first shaft 10 or the second shaft 20) form an angle of angle of 30° to 60°.

In a preferred embodiment, the angle of 45° is selected to facilitate operation and push fit between the actuator 11, the secondary actuator 12, the reactor 22, the secondary reactor 23, and the linkage 30.

It can be understood that, considering the axis of the first shaft 10 or the second shaft 20 as a reference, the inclination direction of the first oblique side b1 of the ejector 11 and the sub-actuator 12 is opposite to the reactor 22 and the sub-reactor. The inclination direction of the first oblique side b1 of 23; the inclination direction of the second oblique side b2 of the actuator 11 and the sub-actuator 12 is opposite to the inclination direction of the second oblique side b2 of the reactor 22 and the sub-reactor 23. And, the spiral direction of the urging track 13 is opposite to the spiral direction of the reaction track 24.

Referring again to Figures 12, 13 and 14, the yoke track 13 corresponding to the second oblique side b2 of the ejector and the second oblique side b2 of the secondary ejector, and the second oblique side b2 of the reactor and the second secondary reactor The opposite side of the oblique side b2 In the track 24, the connector 30 forms a shape of a piece. In conjunction with the shapes of the ejector 11, the sub-actuator 12, the reactor 22, and the sub-reactor 23, the actuator 30 is formed with a first concave surface 35 and a second concave surface 36; the first concave surface 35 is provided with an urging pile 33, and the second concave surface 36 A reaction pile 34 is provided. The urging pile 33 and the reaction pile 34 are located inside the above-mentioned levitation rail 13 and the reaction rail 24, respectively.

Referring to Figures 15, 16 and 17, when the first shaft 10 drives the actuator 11 to rotate, the urging rail 13 is engaged, and the relative actuator 30 is displaced in the direction parallel to the first shaft 10 and the second shaft 20, forcing. The reaction pile 34 pushes the reactor 22 along the reaction track 24 to cause the second shaft 20 (and the sub-reactor 23) to produce a synchronous rotational movement in the direction of rotation of the opposite first shaft 10.

In detail, Fig. 15 shows the position where the first axis 10 and the second axis 20 are positioned (i.e., the display module 91 is closed on the body module 92 in Fig. 1) at an angle defined as 0°. When the operator rotates the first shaft 10 to drive the actuator 11 (or the sub-actuator 12) by 90°, the urging rail 13 pushes the urging pile 33 of the coupling 30 to displace the coupling 30 to the left in the figure; for example, Figure 16 depicts the situation.

Referring to Figures 16 and 17, when the actuator 30 is displaced, the reaction pile 34 is displaced along the reaction track 24 toward the left in the figure, pushing the reactor 22 (or the secondary reactor 23), forcing the reactor 22 to move toward the opposite side. The direction in which the device 11 (or the sub-actuator 12) moves is rotated to cause the second shaft 20 and the sub-reactor 23 to produce a synchronous rotational motion.

Therefore, Fig. 16 shows the transmission of the actuator 11, the sub-actuator 12, the coupling 30, the reactor 22, and the sub-reactor 23 when the operator rotates the first shaft 10 by 90° counterclockwise. The two shafts 20 are synchronously rotated clockwise to a position of 90°; that is, the first shaft 10 and the second shaft 20 (or the display module 91 and the body module 92) are rotated by a total range of 180°.

Fig. 17 depicts a position in which the second shaft 20 is rotated clockwise to 180° when the first shaft 10 is rotated 180° counterclockwise; that is, the first shaft 10 and the second shaft 20 (or the display module 91). The body module 92) is rotated a total of 360°.

It should be noted that the fourth embodiment shown in FIGS. 12 to 17 is linked to the fourth embodiment (or the second and third embodiments) as compared with the first embodiment disclosed in FIGS. 2 to 5. The length of the device 30 is significantly smaller than that of the first embodiment (Figs. 2-5). For example, assume that the lengths of the actuator 11, the sub-actuator 12 (or the reactor 22, the sub-reactor 23) and the interlock 30 of the first embodiment on the first shaft 10 (or the second shaft 20) are 24 mm. The total length of the actuator 11, the sub-actuator 12 (or the reactor 22, the sub-reactor 23) and the linker 30 of the fourth embodiment on the first shaft 10 (or the second shaft 20) is only about 13 mm. The fourth embodiment significantly shortens the length and volume of the entire synchronous motion device.

Referring to Figures 18, 19 and 20, yet another possible embodiment (fifth embodiment) of the present invention for a synchronized motion device for a dual spindle system is depicted. The actuator 11 is a columnar structure (or the actuator and the sub-actuator are integrally formed) a columnar structure) is disposed at the pivot end 10b of the first shaft 10, and the actuator 11 is recessed with a (helical) urging track 13; and the reactor 22 is a columnar structure (or reactor and The sub-reactor is integrally formed with a columnar structure) disposed at the pivot end 20b of the second shaft 20, and the reactor 22 is recessed with a (helical) reaction track 24.

It can be understood that, assuming that the axis of the first shaft 10 or the second shaft 20 is used as a reference, the spiral direction of the urging rail 13 is opposite to the spiral direction of the reaction rail 24.

Referring again to Figures 18, 19 and 20, corresponding to the trajectory track 13 of the ejector 11 and the reaction track 24 of the reactor 22, the splicer 30 is formed into a shape of a piece of body, provided with an urging pile 33 and a reaction The piles 34 are located inside the above-described levitation rails 13 and reaction rails 24, respectively.

Referring to Figures 21, 22 and 23, when the first shaft 10 drives the actuator 11 to rotate, the urging rail 13 is engaged with the relative movement of the linkage 30 in the direction parallel to the first shaft 10 and the second shaft 20, forcing. The reaction pile 34 urges the reactor 22 to rotate along the reaction track 24 to cause the second shaft 20 to produce a synchronous rotational movement in the direction of rotation of the opposite first shaft 10.

In detail, Fig. 21 shows the position where the first axis 10 and the second axis 20 are positioned (i.e., the display module 91 of Fig. 1 is closed on the body module 92) at an angle defined as 0°. When the operator causes the first shaft 10 to rotate the actuator 11 by 90°, the urging rail 13 pushes the urging pile 33 of the coupling 30 to displace the coupling 30 to the left in the drawing; for example, the situation depicted in Fig. 22.

Referring to Figures 22 and 23, when the actuator 30 generates a displacement motion, the reaction pile 34 is displaced along the reaction track 24 toward the left in the figure, and the reactor 22 is pushed to rotate in the direction of the movement of the opposite actuator 11, so that the second shaft 20 Produces a synchronous rotational motion.

Therefore, Fig. 22 shows that when the operator rotates the first shaft 10 by 90° counterclockwise, the actuator 11 cooperates with the transmission of the actuator 30 and the reactor 22 to rotate the second shaft 20 clockwise to 90°. The position of the first shaft 10 and the second shaft 20 (or the display module 91 and the body module 92) are rotated by a total of 180 degrees.

Figure 23 depicts the second shaft 20 rotated clockwise to a position 180° when the first shaft 10 is rotated 180° counterclockwise; that is, the first shaft 10 and the second shaft 20 (or the display module 91) The body module 92) is rotated a total of 360°.

Typically, this synchronous motion device for a dual-spindle system has the following considerations and advantages over the old method when it has operational rotation and positioning:

1.

Between 91 and the body module 92; allowing the operator to operate only the display module 91 to rotate 0 ° ~ 180 °, the body module 92 is also relatively synchronous rotation 0 ° ~ 180 °, and the display module 91 and the body module The total angle of rotation of 92 reaches a range of 360°. That is to say, the synchronous motion device allows the user to operate the display module 91 to rotate by an angle or a range, and the rotation angle or the range of the double stroke can be obtained. Under the condition that the electronic device 90 is provided with more kinds of operation modes (or application ranges), the operation is simple and convenient.

3. The actuator 11 (and/or sub-actuator 12), the reactor 22 (and/or the sub-reactor 23) cooperate with the synchronous transmission structure design of the linkage 30, which not only provides a transmission mechanism different from the prior art. And related mating structure; and, like the conventional wire or the transmission belt, the kinetic energy transmission delay occurs; or the wire and the runner combination have a gap, and the slip or the actuation is not sure in the process of the cooperative driving operation; or the fixing of the wire and the runner combination The structure is not ideal, and the traction pull phenomenon caused by the wire load or the transmission of power is increased, and the transmission effect is reduced, and the like is obviously improved.

4. The actuator 11 (and/or the secondary actuator 12), the reactor 22 (and/or the secondary reactor 23) cooperate with the synchronous transmission structure design of the linkage 30, Compared with the old method, it is not only advantageous for manufacturing and assembly; and the spacing of the first and second shafts 10, 20 and the length of the synchronous transmission are allowed to be reduced as much as possible to reduce the space of the entire transmission or structure or The volume is more in line with the light and thin design requirements of the electronic device.
