Description

technical field

The utility model relates to a torsion changing device for a multi-section rotating shaft; in particular to a rotating shaft structure that can be combined with electronic equipment to form multiple rotating shaft centers. A new type that generates a torque difference.

Background technique

Equipped with pivots or shafts that can rotate freely due to external forces on electronic appliances, such as mobile phones, notebook computers, PDAs, digital cameras, e-books, etc., so that their covers, display screens or viewing windows can be rotated and have The opening and closing functions are existing technologies. For example, Chinese Taiwan Patents No. 97222022 "Rotating Shaft Structure", No. 96217011 "Pivot Positioning Member", and No. 98207366 "Pivot Structure" provide typical embodiments.

Assuming that an electronic device such as a notebook computer is taken as an example, it usually includes a body module at the end and a display module for display; the body module and the display module are connected by a pivot, and the display module can be connected by the pivot. The axis of action is opened upwards to be in the use state, or reversely closed on the display module to the body module to be in the closed state. The importance of this type of pivot is that it is not only the axis of action of the electronic device, but the structural design must also take into account the position where the display module is opened to reach the operating angle (for example, the display screen of a notebook computer is usually opened to about 135°) At this time, the structure of the pivot itself can have enough supporting force to provide the positioning of the display screen or the display module at the operating angle position.

In order to make the display module (for example, screen) and/or the body module of the electronic device have more operation modes and application ranges in use, the prior art has also disclosed a dual-rotation shaft between the display module and the body module. , so that the display module and/or the body module can produce different operation modes or structures of rotation angles. For example, Chinese Taiwan No. 99211350 "Double Pivot Hinge", US 7512426B2 "MOBILE COMMUNICATIONS DEVICE WITH SYNCHRONISING HINGE" patent case, etc., all provide feasible embodiments.

A problem related to the operation, movement and structural design of this type of rotating shaft or pivot is that the above-mentioned existing pivots are usually arranged in two groups of distributions in an electronic The position on both sides of the pivot joint of the display module of the device (such as a notebook computer) and the end edge of the body module. Therefore, when the display screen is operated or the display module is rotated and lifted, the coordination of the rotating shaft is not ideal; at the same time, the degree of freedom of rotation of the two pivots arranged close to the same center line is also limited, so that the entire electronic device is opened or closed. In the closed rotation process, the movement smoothness is poor.

In order to improve the above situation, the prior art also discloses a technical means in which a pivot device uses multiple rotation centers; "Structure" patent cases, etc., provide specific embodiments. The reference data is applied to the combination of the active joint group and the follower joint group; an intermediate linkage group is set between the two opposite joint plates of the active joint group, and the two opposite joint plates are provided with a synchronous driving part to connect the middle joint Moving set. The follower joint group has two follower pieces, which are arranged between two opposite joint pieces of the active joint group. The positions of the relative joint pieces toward the inner end correspond to the positions of the follower pieces toward the outer end, and a pivot pin is combined; the position of the outer end of the above-mentioned intermediate link group corresponds to the position of each follower piece toward the inner end, and a pivot pin is combined; Most of the active joint groups and the follower joint groups are arranged in parallel, freely rotating with multiple rotation centers, and together form a multi-section rotating shaft structure.

Typically, these reference data show the situation with regard to the use and structural design of the shaft or its associated components. If the redesign considers the structure of the shaft and related components, as well as the above-mentioned application situations, making it different from the existing technology, it will change its use pattern and be different from the old method; in essence, it will also increase its application. Ease of use in terms of scope and operation. Therefore, the following topics were considered:

It is considered to provide a torsion joint mechanism to increase the stability and positioning or fixing effect of the synchronous rotating shaft in terms of operation and cooperation under the condition of conforming to the structural design of synchronous motion and easy operation.

At the same time, the quantity or torque of the torsion joint mechanism can be easily changed or adjusted according to the transmission specifications, and it meets the light and thin shape design requirements of electronic appliances.

Further consider the application of joint groups in the process of synchronous movement, so that they produce interference (quantity) changes, and relatively change the distance of the rotating shaft, resulting in the effect of torque difference.

None of these issues are specifically taught or disclosed in the aforementioned references.

The sub-follower joint group 700 at least includes a first sub-follower 710 and a second sub-follower 720 composed of one or more plate structures, which are arranged on the first joint plate 80 and the second joint plate of the torsion joint group 100 Between 90. The first sub-follower 710 and the second sub-follower 720 are respectively provided with two separate "outward" shaft holes 711, 721 and "inward" shaft holes 712, 722, which are respectively used for pivoting the first pivot pin 71. The second pivot pin 72, the third pivot pin 73, and the fourth pivot pin 74.

In the adopted embodiment, the first sub-follower 710 and the second sub-follower 720 are provided with synchronous driving parts 713, 723; when the active joint group 10 or the torsion joint group 100 rotates due to the operation of the electronic device A by a person, the first secondary follower 710 and the second secondary follower 720 cooperate with the synchronous driving parts 713, 723 and the follower joint group 70 Create synchronous motion.

In a preferred embodiment, the synchronous driving parts 713 and 723 of the first sub-follower 710 and the second sub-follower 720 of the sub-follower joint group 700 respectively define a zone, a b zone connecting the a zone, The c area connecting the b area; the distance from the b area to the shaft hole 712 or 722 is greater than the distance from the a area (or c area) to the shaft hole 712 or 722, so that the b area is compared with the a area and the c area to form a Similar to the cam structure. That is, the distance from zone b to the third pivot pin 73 or the fourth pivot pin 74 is greater than the distance from zone a (or c zone) to the third pivot pin 73 or the fourth pivot pin 74).

Therefore, when the b-zones of the synchronous driving parts 713, 723 of the first sub-follower 710 and the second sub-follower 720 are in contact with each other or at the closest position, the first sub-follower 710 and the second sub-follower 710 The amount of interference of the secondary follower 720 is the largest, at least forcing the third pivot pin 73, the fourth pivot pin 74 and/or the first pivot pin 71, and the second pivot pin 72 to change positions or distances, pushing the torsion joint group 100, and Torque variation or difference is produced; this section is also described below.

The figure depicts that after the above-mentioned active joint group 10, torsion joint group 100, follower joint group 70, and secondary follower joint group 700 are merged and arranged, the two opposite first joint pieces 20, 80 and the second joint piece can The "inward" shaft holes 22, 82, 32, 92 of 30, 90 are respectively aligned with the first follower 50, the second follower 60, the first secondary follower 710, and the second secondary follower 720. The "outward" shaft holes 51, 61, 711, 721 are pivotally connected or passed through the first shaft pin 71 and the second shaft pin 72, and are combined into one body by a series of pivots. And, the shaft holes 41, 401, 42, 402 at both ends of the linkages 40, 400 of the active joint group 10 and the torsion joint group 100 are respectively aligned with the first follower piece 50, the second follower piece 60, the first follower piece The “inward” shaft holes 52 , 62 of the actuator 710 and the second secondary follower 720 are pivotally connected or passed through the third pivot pin 73 and the fourth pivot pin 74 .

Therefore, a plurality of active joint groups 10, torsion joint groups 100, follower joint groups 70, and secondary follower joint groups 700 are arranged in parallel to combine the first pivot pin 71, the second pivot pin 72, the third pivot pin 73, The fourth shaft pin 74 together forms a multi-section rotating shaft structure with elastic clamping positioning force and torsional force variation.

As shown in Figure 3, it depicts the situation where the display module A1 is covered with the body module A2; the a-zone of the first secondary follower synchronous driving part 713 and the second secondary follower synchronous driving part 723 of the secondary follower joint group 700 The a-regions are in contact with each other or the closest position.

Fig. 3 and Fig. 4 show that according to the above-mentioned embodiment, when one of the joint pieces (ie, the first joint pieces 20, 80 or the second joint pieces 30, 90) of the active joint group 10 and the torsion joint group 100 rotates and swings, "inwardly" "The synchronous driving part 23, 83 or 33, 93 will be combined with the "outward" connecting part 43, 403 or 44, 404 of the middle linker 40, 400, and then drive the linker 40, 400 to produce a relative The reverse rotation synchronously moves the first follower piece 50 and the first secondary follower 710 of the follower joint group 70 and the auxiliary follower joint group 700, so that the entire multi-section shaft structure is equipped with a torsion joint group In the case of 100 functions, a synchronous rotation state is formed.

The figure shows that when one joint plate (the first joint plate 20, 80 or the second joint plate 30, 90) of the active joint group 10 or the torsion joint group 100 is forced to swing, the other relative joint plate will be affected synchronously And swing. That is to say, when the "outward" end of the first joint plate 20, 80 is assumed to swing in a clockwise direction (that is, the state in FIG. 3 is rotated to the state shown in FIG. 4), the first joint plate 20, 80, the "inward" end will generate a clockwise rotational displacement relative to the outer circumference of the "outward" end of the linkage 40, 400, and the first follower piece 50 and the first secondary follower 710 "toward" will be pulled in conjunction with each other. The "outer" ends are displaced in the same direction; and the "inward" ends of the first follower piece 50 and the first secondary follower 710 are also rotated clockwise.

And, between the first follower piece 50 and the second follower piece 60, between the first sub-follower 710 and the second sub-follower 720, the synchronous driving parts 53, 63, 713, 723 are engaged and connected. Move, so that the "inward" ends of the second follower piece 60 and the second secondary follower 720 that are connected to each other rotate counterclockwise synchronously; that is, the b of the first follower piece 50 and the first secondary follower 710 The zone gradually engages or touches the b zone of the second follower piece 60 and the second sub-follower 720; therefore, the "outward" ends of the second follower piece 60 and the second sub-follower 720 are relatively generated Swivel counterclockwise.

The figure also shows that the two opposing first joint pieces 20, 80 and second joint pieces 30, 90 of the active joint group 10 and the torsion joint group 100 will therefore produce synchronous reverse swings based on the center line C , together form a relatively open or closed action, or at least one of the relative joint plates swings toward the other relative joint plate to approach (close) or move away from (open); for example, the situation depicted by the imaginary line in Figure 4.

It can be understood that the relative swing angle between the two relative joint pieces (20, 30 or 80, 90) can range from 0° to 360°, so that an ideal degree of freedom of rotation is established. Moreover, the torsion joint group 100 also provides the function of positioning the electronic appliance A immediately when the operating force disappears during the opening and closing operation process.

It must be noted that the solid line in FIG. 4 particularly shows the area b of the first auxiliary follower synchronous driving part 713 and the b area of the second auxiliary follower synchronous driving part 723 of the auxiliary follower joint group 700 , have reached the position where they touch each other or are closest to each other; at this time, the amount of interference between the first secondary follower 710 and the second secondary follower 720 is the largest, at least forcing the third pivot pin 73, the fourth pivot pin 74 and /or the first pivot pin 71 and the second pivot pin 72 change positions or distances (for example, the situation depicted by the imaginary line in FIG. 4 ), push the torsion joint group 100 to expand the gaps 405, 406 and/or gaps 84, 94; The reaction force generated by the torsion joint group 100 or instinctively clamp the third pivot pin 73, the fourth pivot pin 74 and/or the first pivot pin 71, and the second pivot pin 72, so as to produce the effect of torque variation or torque difference . The effect of the torque variation or torque difference can make the opening and closing operation of the display module A1 and the body module A2 achieve a more reliable positioning effect.

In particular, when the first sub-follower 710 and the second sub-follower 720 are going to enter the area b with a large amount of interference from the area a (or area c) with a small amount of interference, an automatic positioning will occur. effect. Therefore, the cam shape and profile of the a zone, b zone, c zone or b zone of the synchronous driving part 713, 723 via the secondary follower joint group 700 (or the first secondary follower 710, the second secondary follower 720) The structural design can be controlled or adjusted to change the above-mentioned position or angle that produces the automatic positioning effect.

As shown in Figures 5 to 7, a modified embodiment of the present utility model is shown.

That is to say, in this embodiment, the secondary follower joint group 700 is removed. Therefore, the follower joint group 70 includes the first follower piece 50, the second follower piece 60, the "outward" shaft holes 51, 61, the "inward" shaft holes 52, 62 and the synchronous driving joints engaged with each other as described above. Parts 53, 63; And, the synchronous driving parts 53, 63 of the follow-up joint group 70 (or the first follow-up piece 50, the second follow-up piece 60) respectively define a zone, b zone connecting a zone, connecting b The c area of the area; the distance from the b area to the shaft hole 712 or 722 is greater than the distance from the a area (or c area) to the shaft hole 52 or 62, so that the b area is compared with the a area and the c area to form a similar The cam structure of the teeth. That is, the distance from zone b to the third pivot pin 73 or the fourth pivot pin 74 is greater than the distance from zone a (or c zone) to the third pivot pin 73 or the fourth pivot pin 74).

Therefore, the solid line part of Fig. 8 has particularly shown the b zone of the first follower piece synchronously guiding part 53 of this follower joint group 70, the b zone of the second follower piece synchronously guiding part 63, have reached mutual engagement or The closest position; at this moment, the interference amount of the first follower piece 50 and the second follower piece 60 is the largest, at least forcing the third shaft pin 73, the fourth shaft pin 74 and/or the first shaft pin 71, the second The pivot pin 72 changes position or distance, and pushes the torsion joint group 100 to expand the gaps 405, 406 and/or gaps 84, 94; the reaction force produced by the torsion joint group 100 or instinctively clamps the third pivot pin 73, the fourth The shaft pin 74 and/or the first shaft pin 71 and the second shaft pin 72 generate torque variation or torque difference.

That is to say, the effect of the torque variation or torque difference can make the opening and closing operation of the display module A1 and the body module A2 achieve a more reliable positioning effect. In particular, when the first follower piece 50 and the second follower piece 60 are about to enter zone a (or c) with a small amount of interference into zone b with a large amount of interference, an automatic positioning function will be produced. Therefore, via the follower joint group 70 (or the first follower piece 50, the second follower piece 60) the structural design of the cam shape and the profile of the a zone, b zone, c zone or b zone of the synchronous driving part 53,63 , it will be possible to control or adjust to change the above-mentioned position or angle that produces the automatic positioning effect.
