Transmission for pivots

The present invention relates to a transmission device for a pivoting device; in particular, an actuating portion that moves in conjunction with a pivot or a rotating shaft, an actuator equipped with an elastic body, and a steering gear to cause the carrier to load and lift a base body The new type of sports.

The utility model is equipped with a pivot or a rotating shaft which can be reciprocally rotated by an external force, and is mounted on an electronic object, such as a mobile phone, a notebook computer, a PDA, an e-book, etc., so that the cover or the display screen can be rotated to have an opening and closing function. The department has been a skilled skill. For example, Taiwan Patent No. 97222022 "Rotary Shaft Structure", No. 98207366 "Pivot Structure", No. 99211350 "Double Pivot Hub" and the like 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 devices, conventional techniques have also disclosed a display module and/or a body module. When rotating, a frame is driven to move up and down to protect and prevent the structure of the keyboard disposed on the body module from being accidentally touched. For example, Figure 1 provides a possible embodiment.

Fig. 1 depicts a body module A1 of an electronic device A equipped with a (double) shaft B and a casing C covering the shaft B. The shaft B has an eccentric portion B1 which is eccentrically rotated as the shaft B rotates. A carrier B2 connected to the eccentric portion B1 is combined with a carrier B4 in cooperation with a connecting portion B3. When the user operates the display module or the body module A1 is rotated and opened by 180° to 360°, as a type similar to that used by the tablet computer, the eccentric portion B1 of the rotating shaft drives the transmission frame B2, the connecting portion B3 and the carrier B4 to generate (longitudinal) displacement. The carrier B4 pushes the frame A2 disposed on the body module A1 to generate a lifting movement, so that the height of the frame A2 is higher than the keyboard A3, and serves as a support frame for the load electronic object; and, the protection and the blocking are set in the body module A1. The keyboard A3 on the keyboard is mistakenly touched.

A problem related to the operation and structural design of the above embodiment is that in order to allow the transmission frame B2 and the shaft eccentric portion B1 to be connected and transmitted, the casing C must form a notch C1 for the transmission frame B2 to pass and move; obviously, the gap C1 affects the overall design and visual sense of the electronic object A, and it is easy for dust or the like to accumulate on the components inside the casing C, which is not desirable.

Another problem with the assembly and structural design of the transmission of such a shaft is that the connecting portion B3 must be provided with a claw portion B5 for fastening the carrier B2; and a base frame A4 disposed at the bottom of the body module A1. The L-shaped limiting plate A5 combines the convex portion B6 formed on the connecting portion B3 so that the connecting portion B3 is restrained on the base frame A4 and moves with the carriage B2. As is known to those skilled in the art, the mating structure between the carrier B2, the connecting portion B3 and the base frame A4 is relatively complicated, which also increases the difficulty and troublesome situation of their assembly.

Typically, these references show the use and structural design of the shaft, transmission or its associated assembly. If the redesign considers the transmission and related component structure, as well as the application described above, to make it different from the conventional one, it will be able to change its use type and increase its application range, which is different from the old one. For example, in contrast to conventional techniques, the transmission is applied to a notebook computer or a small electronic device to provide a security mechanism and maintain the package in accordance with a lightweight, thin design. The integrity of the casing of the overturning shaft improves the design and visual sense of the electronic device as a whole, and it is easy to accumulate dust or the like; or further complicates the complicated structure of the prior art, and increases the difficulty and trouble of assembly. In other cases, significant improvement is achieved. None of these topics have been specifically taught or disclosed in the above patents.

Therefore, the main purpose of the present invention is to provide a transmission device for a pivotal device, which provides a safety mechanism and a simple assembly function; and includes at least one rotating shaft, an actuating portion that moves in response to the rotation of the rotating shaft, and generates ( Horizontal) reciprocating or displaced drive. The driver includes an arm having an elastomer and a hand connecting the arms; and a diverter having a first end connecting the driver and a second end combining a carrier. When the lateral displacement of the drive causes the steering gear to oscillate, the second end of the steering gear drives the carrier to load a base or frame to generate a lifting motion to conform to the mode in which the user operates the electronic object.

According to the present invention, a pivoting device for a pivoting device includes a pivoting region of a combined torque module and a fixed region pivotally connected to a body module or a display module. The rotating shaft is disposed between the pivoting area and the fixed area, and the actuating part is disposed; corresponding to the actuating part, the driver is provided with a guiding part, and the actuating part is combined, so that the guiding part is driven by the rotation of the actuating part Drive motion.

According to the present invention, for a transmission device for a pivot, the rotating shaft includes a first rotating shaft and a second rotating shaft; the first rotating shaft is pivotally connected to the body module of the electronic object; and the second rotating shaft is pivotally connected to the display module of the electronic object. And a coupling is disposed between the first rotating shaft and the second rotating shaft to synchronously rotate the first rotating shaft and the second rotating shaft.

According to the present invention for a transmission for a pivot, the arm of the drive is provided with a guide rail that cooperates with a first end of the pivoting steering gear and allows the first end of the steering gear to move on the guide rail. And, the elastic body has two ends, one end is fixed on the arm portion of the driver, and the other end is matched with the first end of the bolt pivoting steering gear to provide one elastic movement range of the steering gear movement.

If external forces or misoperations prevent the base or frame from moving up and down, the elastomer allows the actuator or the first end of the diverter to stretch the elastomer to prevent external forces from damaging the transmission.

Referring to Figures 2 and 3, the transmission for the pivot is a combination of an electronic device (e.g., a computer) with a dual shaft as an illustrative embodiment. The rotating shaft includes a first rotating shaft 10 and a second rotating shaft 20; the first and second rotating shafts 10, 20 respectively include fixing portions 11, 21 and pivoting portions 12, 22.

The second shaft fixing area 21 is connected to the display module 32 of the electronic object 30. The pivoting regions 12 and 22 of the first and second rotating shafts 10 and 20 (respectively) are combined with the torque module 40 to rotate the first and second rotating shafts 10 and 20 in the user's operation of the body module 31 or the display module 32. When the force disappears, the positioning effect is obtained. The torsion module 40 is a known structure and will not be described in detail.

In the embodiment taken, an actuator 41 is disposed between the first shaft 10 and the second shaft 20 to cause the first shaft 10 and the second shaft 20 to rotate synchronously. Specifically, the first and second rotating shafts 10 and 20 are connected to the pivoting regions 12 and 22 at positions of spiral grooves 13 and 23; corresponding to the spiral grooves 13 and 23, both ends of the connecting body 41 are provided with convex portions 42 respectively embedded therein. Spiral grooves 13, 23. Therefore, when the user operates the display module 32 to rotate to drive the second rotating shaft 20 to rotate, the coupling 41 is forced to rotate the first rotating shaft 10 and the body module 31.

Also shown is a pair of shells 44 covering the first and second shaft helical grooves 13, 23, the interlocking body 41, and the secondary shell 44 engaging a limiting plate 46, which is assembled with the torsion module 40 in a casing 45. . The limiting plate 46 is provided with two holes 47 for respectively passing the pivoting regions 12, 22 of the first and second rotating shafts 10, 20; after the pivoting regions 12, 22 pass through the auxiliary casing 44, the torque module 40 is combined.

In a preferred embodiment, the first rotating shaft 10 is provided with an engaging portion 14 between the fixed portion 11 and the pivoting portion 12; the actuating portion 14 is a tubular body having a shaft hole 15 fitted therein. On the first shaft 10 . The surface of the actuating portion 14 is formed with a traction zone 16; the traction zone 16 is a track or groove structure comprising an (annular) straight section 16a and a (helical) oblique section 16b connecting the straight sections 16a.

Figure 3 depicts the end of the actuating portion 14 with a shoulder 17 and a block 18 formed on the shoulder 17; the insert 18 is embedded in a hole 48 formed in the limiting plate 46. Therefore, when the user operates the display module 32 and the second rotating shaft 20 rotates to rotate the first rotating shaft 10 and the body module 31, the casing 45 and the limiting plate 46 also rotate the actuating portion 14.

Figure 3 also shows that the traction zone 16 of the actuator 14 incorporates a reciprocable or displaceable drive 50. In the embodiment taken, the driver 50 includes a hand 51 and an arm portion 52 that connects the hand 51; the hand 51 and the arm portion 52 are L-shaped. Corresponding to the tubular body structure of the actuating portion 14, the hand portion 51 is formed with an arc portion 51a and a guide portion 53 provided on the arc portion 51a; the guide portion 53 is a structure of a stud which is embedded in the traction portion 16. It is assumed that the body module 31 and the display module 32 are in the closed position, and the guiding portion 52 is at the starting point of the straight section 16a of the traction zone; therefore, the end point of the straight section 16a refers to the connection of the straight section 16a and the oblique section 16b. position.

The figure also depicts that a partial or full area of the driver arm 52 is a multi-layer structure having a first portion 52a, a second portion 52b and a space or recess formed between the first portion 52a and the second portion 52b. The chamber 52c; and the arm portion 52 or the second portion 52b is provided with a groove chamber 54 for mounting an elastic body 56. The elastic body 56 is a coil spring having two ends, one end of which is fixed to the column 57 from which the arm portion 52 (or the groove chamber 54) protrudes; the other end is fitted with a bolt 55 for pivoting the arm portion 52 and a diverter 60. The elastomer 56 provides a range of elastic motion for the movement of the diverter 60.

In detail, with respect to the position of the post 57, the arm portion 52 (or the first portion 52a) is provided on the other side with an elongated hole type guide rail 58 communicating with the recess 52c and the slot chamber 54; and, the diverter 60 is a The L-shaped plate-like body has a first end 61, a second end 62, and an intermediate portion 63 connected between the first and second ends 61, 62. The first end 61 of the diverter extends into the recess 52c; the first end 61 is provided with a combined hole 64, and the first end 61 (or the combined hole 64) and the other end of the elastic body 56 are pivotally connected to the plug 55. On the guide rail 58, the elastic body 56 has a predetermined force. When an external force is greater than the predetermined force, the elastic body 56 allows the steering gear 60 or the first end 61 to move on the guide rail 58 (this portion will be described later). ).

In the preferred embodiment, the second end 62 of the diverter 60 has a combined aperture 65 that is pivotally attached to a track 34 of the fixed plate 33 in conjunction with the retainer 70; the track 34 has a raised aperture configuration. The intermediate portion 63 has a combination hole 66, which is coupled to the fixing bolt 71 and pivotally connected to the fixing plate 33 of the body module 31 to form a pivoting or swinging fulcrum. Thus, the diverter 60 moves the second end 62 over the track 34 as the driver 50 moves.

Specifically, the position at which the first end 61 of the diverter and the peg 55 are initially combined on the guide rail 58 is defined as a first position; after the first end 61 and the peg 55 are moved, defined as the second position. The position at which the diverter second end 62 and the retainer 70 are combined on the track 34 is defined as the initial position; the position at which the second end 62 and the retainer 70 move to the other end of the track 34 as the drive 50 moves is defined as the end position.

It should be noted that, assuming that the axial direction of the guide rail 34 is the reference axis, the direction in which the second end 62 of the steering gear 62 and the retainer 70 are displaced on the rail 34 in the figure is defined as a longitudinal displacement; therefore, the direction perpendicular to the longitudinal displacement Defined as lateral displacement. In the embodiment taken, the axial direction of the guide rail 58 is perpendicular to the axial direction of the rail 34; therefore, the direction of displacement of the first end 61 of the diverter and the bolt 55 on the guide rail 58 is laterally displaced.

It is also shown that the second end 62 of the steering gear is pivotally coupled with a carrier 80 in conjunction with the holder 70. The carrier 80 is disposed on the body module 31, as is conventional in the art to facilitate a lifting motion of a substrate or frame (not shown).

Please refer to Figures 4, 5 and 6, and Figure 4 depicts the case where the body module 31 and the display module 32 are in the closed position, and the guiding portion 53 is located at the starting point of the straight section 16a of the traction zone. 5 and 6 show that when the user operates the display module 32 and the second rotating shaft 20 to rotate by 90°, and when the movable body module 31 and the first rotating shaft 10 are rotated by 90°, the casing 45 and the limiting plate 46 are also driven. The actuating portion 14 rotates on the first rotating shaft 10. Therefore, the driver guide 53 is relatively displaced to the end position of the actuating portion straight section 16a. At this point, the diverter first end 61 and the peg 55 are still in the first position of the rail 58; the second end 62 and the retainer 70 are still in the initial position of the track 34.

Referring to FIGS. 7 and 8, the user operates the display module 32 and the second rotating shaft 20 to rotate 180°, and when the movable body module 31 and the first rotating shaft 10 are relatively rotated by 180°, the casing 45 is also restricted. The plate 46 drives the actuating portion 14 to rotate on the first shaft 10. Therefore, the driver guide 53 is relatively displaced from the end position of the straight portion 16a of the actuating portion into the oblique portion 16b or to the end position of the oblique portion 16b, causing the arm portion 52 (and the elastic body 56) of the actuator 50 to be laterally displaced. The steering gear 60 is driven by the combined hole 66 and the fixing bolt 71 of the intermediate portion 63 as a rotating or swinging fulcrum, so that the second end 62 is longitudinally displaced from the initial position toward the end position (upper in the figure) on the rail 34, and the carrier 80 is pulled toward The upper movement in the figure causes the carrier 80 to push the base or frame up to the highest position. The highest position of the frame is already higher than the keyboard position, and the conventional art is used as a support frame for the load electronic device; and, the function of protecting and preventing the keyboard disposed on the body module from being accidentally touched is achieved.

Please refer to FIG. 9. It should be noted that, when the steering device 60 pulls the carrier 80 to move, if the operator mistakenly presses the frame so that the frame cannot rise smoothly, it is assumed that the wrong pressure is greater than the preset force of the elastic body 56. It is associated with the fact that the steering gear 60 cannot swing with the movement of the drive 50. Thus, the post 57 (or the diverter first end 61 is moved relative to the second position of the rail 58) relative to the displacement of the driver 50 stretches the elastomer 56. The stretchable range allowed by the elastomer 56 should be greater than the displacement distance of the driver 50 (or the length of movement of the first end 61 of the diverter on the rail 58). That is, the elastomer 56 allows the driver 50 and the diverter 60 to have a range of elastic motion, together with a safety mechanism to prevent external forces from damaging the transmission.

It can be understood that when the user operates the display module 32, the second rotating shaft 20 and the body module 31, and the first rotating shaft 10 is rotated and closed from the 180° position, the casing 45 and the limiting plate 46 drive the actuating portion 14 Rotating on the first rotating shaft 10 causes the driver guiding portion 53 to be relatively displaced from the end position of the oblique portion 16b toward the position of the actuating portion straight segment 16a, and drives the driver 50 and the steering gear 60 to return to the initial position, so that the steering gear is The two ends 62 push the carrier 80 toward the lower side of the figure to return to the original position and let the frame descend.

Typically, this transmission for the pivot has the following considerations and advantages over the old method in terms of a lightweight, thin design: 1. The pivot and The related component structure has been redesigned to make it different from the learner and change its use and operation type, which is different from the old method. For example, the rotating shaft (or the first rotating shaft 10) is provided with the actuating portion 14 to cooperate with the driver 50 and the steering gear 60, so that the driver 50 forms the concave chamber 52c, the groove chamber 54 is provided with the elastic body 56, and the arm portion 52 is provided with the guiding rail 58, the pivoting The first end 61 of the steering gear, the second end 62 is movably combined in the rail 34, cooperates with the elastic body 73, so that the driver 50 and the steering gear 60 have an elastic range of motion, and the second end 62 of the steering gear is driven. The movement of the carrier 80 and the like; in essence, the conventional technique is not able to maintain the integrity of the casing, and a large-notch combined transmission device must be provided, which not only affects the overall design and visual sense of the electronic device, but also reduces the casing volume. It is easy to accumulate dust or the like to affect the transmission function. 2. The structural cooperation between the driver 50 of the transmission, the elastomer 56, the diverter 60 and the carrier 80 is convenient for personnel assembly. The joint portion B3 of the prior art is provided with the claw portion B5 fastened to the drive frame B2, the base frame A4 at the bottom of the body module is provided with the L-shaped limit plate A5, and the convex portion B6 of the joint portion B3 is complicated, and the assembly thereof is increased. The difficulty and troubles have also been significantly improved. 3. The above embodiment also shows that if the body module 31 and the display module 32 are mounted with a single shaft combination actuating portion 14, the driver 50 and the diverter 60, the above-mentioned transmission can also be achieved. And the (helical) angle of the straight section 16a and the oblique section 16b of the traction portion 16 of the actuator portion can be adjusted according to actual requirements to change the operation type and angle of the body module 31, the display module 32, and the transmission device. .

Therefore, this creative department provides an effective transmission device for the pivoting device. Its spatial type is different from the conventional ones, and it has the advantages unmatched in the old method. It shows considerable progress. Fully meet the requirements of the new patent.

However, the above is only a feasible embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the equivalent changes and modifications made by the scope of the patent application of the present invention are covered by the scope of the creative patent. .
