Description

Wire arranging mechanism

Technical Field

The present utility model relates to a wire management mechanism, and more particularly, to a wire management tube structure.

Background

In some electronic devices (e.g., notebook computers, etc.), with the development of light and thin design, a flexible printed circuit board (flexible printed circuit, FPC) is generally used as a circuit inside the display screen, and it is required to pass through a rotation axis between an upper housing (e.g., display screen, etc.) and a lower housing (e.g., motherboard, etc.).

As shown in fig. 1A and 1B, the conventional electronic device 1000 includes an upper housing 1100 and a lower housing 1200. The upper case 1100 can rotate relative to the lower case 1200 to open and close the electronic device 1000. The flexible printed circuit board 1300 extends from inside the upper case 1100 into the lower case 1200.

The left side of fig. 1A shows a state in which the electronic device 1000 is closed, and the right side shows a state in which the electronic device 1000 is opened. At the rotation axis between the upper case 1100 and the lower case 1200, the flexible printed circuit board 1300 leaves the upper case 1100 directly from an opening below the upper case 1100 and enters the lower case 1200. The position of the opening has a height difference δ1 during the repeated opening and closing of the upper housing 1100. The height difference δ1 causes the flexible printed circuit 1300 to form a stress concentration point S at the opening, which is prone to damage such as breakage.

Similarly, fig. 1B shows the electronic device 1000 on the left side in a closed state, and the electronic device 1000 on the right side in an open state. The position of the opening of the upper case 1100 in fig. 1B is different from that shown in fig. 1A, but the position of the opening has a height difference δ2 during the repeated opening and closing of the upper case 1100. The height delta 2 is a difference that causes the flexible printed circuit 1300 to form a stress concentration point S at the opening, and is also prone to damage such as breakage.

In addition, the left side of fig. 1C shows a state in which the electronic device 1000 'is closed, and the right side shows a state in which the electronic device 1000' is opened. In the process of repeatedly opening and closing the upper housing 1100, the opening in fig. 1C is maintained at a similar height, but the position of the bending position of the flexible printed circuit board 1300 in the upper housing 1100 still has a height difference δ3, and a stress concentration point S is formed at the bending position. Therefore, the flexible printed circuit board 1300 shown in fig. 1C also has a risk of being easily broken.

In addition, the electronic device 1000' further includes a wire winding device 1500 for receiving the flexible printed circuit board 1300 which is undesirably bent, excessively bent or wrinkled during the opening/closing process of the upper case 1100. Generally, the wire takeup device 1500 may be connected to a printed circuit board (printed circuit board, PCB) or the like disposed in the lower housing 1200, and may include a fixing portion 1510, a winding rod 1520, and an elastic member 1530. The winding bar 1520 has a curved surface contacting the flexible printed circuit board 1300 and is slidable in a horizontal direction with respect to the fixing part 1510 via the elastic member 1530. In this way, the winding rod 1520 provides additional winding space for the flexible printed circuit board 1300 when the upper case 1100 is opened, and the winding rod 1520 can slide and release the flexible printed circuit board 1300 when the upper case 1100 is closed, thereby achieving the accommodating effect. However, the length of travel required for the wire rewinding device 1500 is relatively long (e.g., greater than 5 mm), and the wire rewinding device can only be disposed under the printed circuit board, which is disadvantageous for the light and thin electronic device 1000'.

Therefore, there is a need for a wire management mechanism that can solve the problem of easy breakage of flexible printed circuit boards while achieving a slim and slim mechanism.

Please refer to fig. 2. Fig. 2 is a schematic side cross-sectional view of an electronic device 2000 in a closed and an open state according to some embodiments of the present utility model. As shown in fig. 2, the present utility model provides a wire arranging mechanism 3000 disposed in a housing 2100 of an electronic device 2000. In detail, the housing 2100 may include an upper housing 2110, a lower housing 2120, and a shaft cover 2130. The wire management mechanism 3000 may be disposed within a spindle cover 2130 located between the upper housing 2110 and the lower housing 2120. In the embodiment shown in fig. 2, the hinge cover 2130 is connected to the upper housing 2110. In other embodiments, the shaft cover 2130 may be connected to the lower housing 2120.

As shown in fig. 2, the flexible printed circuit board 2200 passes through a tubular wire arranging mechanism 3000 rotatable with respect to the housing 2100. During the repeated opening and closing of the upper housing 2110, the position of the outlet L of the flexible printed circuit board 2200 hardly changes, and the height difference δ is significantly reduced so that the height difference δ approaches zero. In this way, the risk of breakage of the flexible printed circuit board 2200 due to repeated bending is reduced. The detailed configuration of the wire arranging mechanism 3000 will be described below.

Please refer to fig. 3A and 3B. Fig. 3A and 3B illustrate front and rear views, respectively, of a wire management mechanism 3000, a flexible printed circuit board 2200, and a hinge cover 2130 assembled together, according to some embodiments of the present utility model. In fig. 3A and 3B, the flexible printed circuit board 2200 to which the wire arranging mechanism 3000 is connected is shown in a position where the upper housing 2110 is in an open state. As shown, the wire management mechanism 3000 is disposed within the pivot cover 2130, and the wire management mechanism 3000 may be partially exposed in a front view. In some embodiments, the electronic device 2000 may include one or more wire organizing mechanisms 3000, depending on the number and size of the flexible printed circuit boards 2200. In an embodiment according to the present utility model, the electronic device 2000 may include two sets of wire arranging mechanisms 3000, and the two sets of wire arranging mechanisms 3000 are spaced apart from each other by a certain distance.

Please refer to fig. 4. Fig. 4 illustrates an exploded view of the wire management mechanism 3000, the flexible printed circuit board 2200, and the hinge cover 2130, according to some embodiments of the present utility model. In the embodiment according to the present utility model, the two sets of wire arranging mechanisms 3000 are substantially identical in structure. As shown in fig. 4, each wire arranging mechanism 3000 mainly includes a first tube 3100, a second tube 3200 and a plurality of first elastic members 3300. The first tube 3100 and the second tube 3200 may be fixedly joined together. The flexible printed circuit board 2200 may be clamped between the first tube 3100 and the second tube 3200. The first and second pipe elements 3100 and 3200 coupled together may be connected to the shaft cover 2130 via the first elastic element 3300. The first tube 3100 and the second tube 3200, which are coupled together, can rotate relative to the rotating shaft cover 2130 through the elastic restoring force provided by the first elastic element 3300, which is beneficial to maintaining the position of the outlet L of the flexible printed circuit board 2200. The detailed construction of the first and second tubes 3100 and 3200 will be described below.

Please refer to fig. 5 to fig. 7. Fig. 5 illustrates front and side views of a first tube 3100 according to some embodiments of the utility model. Fig. 6 illustrates front and side views of a second tube 3200, according to some embodiments of the utility model. Fig. 7 illustrates a front view of first tube 3100, second tube 3200, and first resilient element 3300 assembled together, according to some embodiments of the utility model.

As shown in fig. 5, the first tube 3100 mainly includes a first base 3110, a first extension 3120 and a first protrusion 3130. The first base 3110 has a first outer surface 3111 and a first inner surface 3112 opposite the first outer surface 3111. The first extension 3120 is connected to the first base 3110 and extends from the first inner surface 3112. The first protrusion 3130 is connected to the first base 3110 and extends from the first outer surface 3111.

As shown in fig. 6, the second pipe 3200 mainly includes a second base 3210, a second extending portion 3220 and a second protruding portion 3230. The second base 3210 has a second outer surface 3211 and a second inner surface 3212 opposite the second outer surface 3211. The second extension 3220 is connected to the second base 3210 and extends from the second inner surface 3212. The second protrusion 3230 is connected to the second base 3210 and extends from the second outer surface 3211.

In some embodiments, as shown in fig. 7, the first inner surface 3112 of the first base 3110 and the second inner surface 3212 of the second base 3210 are disposed facing each other, and the first extension 3120 and the second extension 3220 are disposed between the first base 3110 and the second base 3210. In some embodiments, first extension 3120 connects to second base 3210 and second extension 3220 connects to first base 3110 such that first tube 3100 and second tube 3200 are joined together.

In detail, in some embodiments, the first tube 3100 has a first positioning hole 3113 on a first inner surface 3112 of the first base 3110 (see fig. 5), and the second tube 3200 has a first connecting portion 3221 on a first surface 3225 of the second extension 3220 connected to the first base 3110 (see fig. 6). The first connecting portion 3221 corresponds to the first positioning hole 3113 in position and shape. First tube 3100 is coupled to second tube 3200 by mating first coupling portion 3221 with first positioning aperture 3113 (e.g., first coupling portion 3221 may be inserted into first positioning aperture 3113).

Further, in some embodiments, the second tube 3200 has a second positioning hole 3213 on the second inner surface 3212 of the second base 3210 (see fig. 6), and the first tube 3100 has a second connection portion 3121 on a second surface 3125 of the first extension portion 3120 connected to the second base 3210 (see fig. 5). The second connection portion 3121 has a position and a shape corresponding to the second positioning hole 3213. The first tube 3100 and the second tube 3200 are further coupled together by the engagement of the second connection portion 3121 with the second positioning hole 3213 (e.g., the second connection portion 3121 may be inserted into the second positioning hole 3213).

In some embodiments, when first tube 3100 and second tube 3200 are joined together, first connection 3221 is inserted into first positioning aperture 3113 and second connection 3121 is inserted into second positioning aperture 3213. At this time, the second surface 3125 of the first tube 3100 has a surface contact with the second inner surface 3212 of the second tube 3200, and the first surface 3225 of the second tube 3200 has a surface contact with the first inner surface 3112 of the first tube 3100.

Additionally, in some embodiments, the first tube 3100 further has a hook 3122 (see fig. 5) on the second surface 3125 of the first extension 3120 connected to the second base 3210, and the second base 3210 further has a recess 3215 (see fig. 6) recessed from the outer periphery. The hook 3122 is located and shaped corresponding to the recess 3215. The first tube 3100 is further fixed to the second tube 3200 by the engagement of the hook 3122 with the recess 3215 (e.g., the hook 3122 may be hooked on the recess 3215). In some embodiments, the hook portion 3122 has a third surface 3123 (see fig. 5). The third surface 3123 faces the second surface 3125. When first tube 3100 is joined with second tube 3200, third surface 3123 contacts second outer surface 3211 of second base 3210, as shown in fig. 7.

In some embodiments, the first protrusion 3130 of the first tube 3100 may have a step 3135 (see fig. 5), and the second protrusion 3230 of the second tube 3200 may have a step 3235 (see fig. 6). Both the step 3135 and the step 3235 can be used to fix the end 3350 of the first resilient element 3300. In detail, as shown in fig. 7, a plurality of (e.g., two) first elastic elements 3300 may be sleeved on the first protruding portion 3130 and the second protruding portion 3230. At this time, the respective end portions 3350 of the first elastic element 3300 may be fixed to the stepped portions 3135 and 3235, respectively, thereby fixing the first elastic element 3300 with the first and second tubes 3100 and 3200.

Please refer to fig. 8A to 8G. Fig. 8A to 8G are schematic views illustrating an assembling process of the wire arranging mechanism 3000, the flexible printed circuit board 2200 and the hinge cover 2130 according to some embodiments of the present utility model, respectively.

In fig. 8A, a flexible printed circuit board 2200 is first placed over a first extension 3120 of a first tube 3100 in the direction of arrow a. At this time, the first tube 3100 is not yet combined with the second tube 3200, the first elastic member 3300, or the shaft cover 2130. In some embodiments, the length of the first extension 3120 is designed to match the width of the flexible printed circuit board 2200, but may also be dependent on the user's needs.

In fig. 8B, a flexible printed circuit board 2200 has been disposed over the first tube 3100. The second tube 3200 is then moved in the direction of arrow B, causing the first connecting portion 3221 of the front end of the second extension 3220 to align with the first positioning aperture 3113 on the first inner surface 3112. The second pipe 3200 is continuously moved until the first connecting portion 3221 is inserted into the first positioning hole 3113. At this time, the flexible printed circuit board 2200 is sandwiched between the first extension 3120 of the first tube 3100 and the second extension 3220 of the second tube 3200.

In the step shown in fig. 8B, while the first connection portion 3221 is aligned with the first positioning hole 3113, the second connection portion 3121 at the front end of the first extension portion 3120 is also aligned with the second positioning hole 3213 on the second inner surface 3212, as shown in fig. 8C. The hook portion 3122 at the front end of the first extension portion 3120 is aligned with the recess portion 3215 of the second base 3210. In some embodiments, instead of moving the second tube 3200 in the direction of arrow B, the first tube 3100 may be moved in the direction of arrow C until the second connection portion 3121 is inserted into the second positioning hole 3213 and the catch portion 3122 catches on the recess 3215.

Fig. 8D shows an enlarged view of a portion of the vicinity of second base 3210 when first tube 3100 and second tube 3200 are joined together. As described above, when the first tube 3100 and the second tube 3200 are joined together, the second surface 3125 of the first extension 3120 contacts the second inner surface 3212 of the second base 3210 and the third surface 3123 of the catch 3122 contacts the second outer surface 3211 of the second base 3210.

Fig. 8E shows a schematic view of the first tube 3100 and the second tube 3200 assembled to the hinge cover 2130 after the first tube 3100 and the second tube 3200 are coupled together. In some embodiments, the shaft cover 2130 includes a plurality of detents 2131. The position and shape of the slot 2131 correspond to the first protrusion 3130 and the second protrusion 3230. The assembled first and second pipe elements 3100 and 3200 are moved in the direction of arrow D until the first and second protruding portions 3130 and 3230 are respectively placed in the respective clamping grooves 2131, so that the first and second pipe elements 3100 and 3200 are connected together with the rotating shaft cover 2130. It should be noted that the card slot 2131 is sized such that both the first protrusion 3130 and the second protrusion 3230 can rotate within the card slot 2131.

Fig. 8F shows a schematic view of the first elastic element 3300 assembled after the first tube 3100, the second tube 3200, and the shaft cover 2130 are fixed together. The first elastic element 3300 moves along the direction of arrow E until the first elastic element 3300 is respectively sleeved on the first protruding portion 3130 and the second protruding portion 3230. As described above, when the first elastic element 3300 is sleeved on the first protrusion 3130 and the second protrusion 3230, the respective ends 3350 of the first elastic element 3300 (the ends 3350 farther from the flexible printed circuit board 2200) may be fixed to the step 3135 of the first protrusion 3130 and the step 3235 of the second protrusion 3230, respectively.

In some embodiments, the shaft cover 2130 includes a plurality of hooks 2132. The hooks 2132 are positioned and shaped to correspond to the first resilient elements 3300, each adjacent to the end 3350 of the flexible printed circuit board 2200. When the first elastic elements 3300 are sleeved on the first protruding portion 3130 and the second protruding portion 3230, one end portion 3350 of each first elastic element 3300 can be fixed on the hook 2132, thereby fixedly connecting at least a portion of the first protruding portion 3130 and the second protruding portion 3230 to the rotating shaft cover 2130. The first tube 3100 and the second tube 3200 coupled together can rotate back and forth relative to the shaft cover 2130 through the elastic restoring force provided by the first elastic element 3300. Fig. 8G shows a schematic view of the wire management mechanism 3000, the flexible printed circuit board 2200, and the shaft cover 2130 assembled. Fig. 8G clearly shows the connection of the hook 2132 to the first resilient element 3300.

Please refer to fig. 9A and 9B. Fig. 9A and 9B illustrate side and perspective cross-sectional views, respectively, of a wire management mechanism 3000, a flexible printed circuit board 2200, and a housing 2100 assembled together in closed and open states, according to some embodiments of the present utility model. As shown in fig. 9A and 9B, the shaft cover 2130 connected to the upper housing 2110 has an opening near the lower housing 2120, and the first tube 3100 and the second tube 3200 may be partially exposed from the opening. And, the flexible printed circuit board 2200 exits the upper housing 2110 through the opening into the lower housing 2120. As can be seen in fig. 9A and 9B, a receiving space 3150 is formed between the first tube 3100 and the second tube 3200. In detail, a receiving space 3150 is formed between the first extending portion 3120 of the first tube 3100 and the second extending portion 3220 of the second tube 3200. The flexible printed circuit board 2200 extends from the upper housing 2110 through the receiving space 3150 to the lower housing 2120.

Advantageously, the flexible printed circuit board 2200 is movable relative to the housing 2100 between an open state and a closed state of the upper housing 2110 as the wire management mechanism 3000 rotates such that the height of the flexible printed circuit board 2200 from the upper housing 2110 remains unchanged (e.g., at the same height as the lower housing 2120). In this way, the height difference δ can be significantly reduced, so that the height difference δ approaches zero, and the flexible printed circuit board 2200 is effectively prevented from being broken or damaged.

Fig. 10 is a side sectional view showing a wire arranging mechanism 3000 including a wire collecting device 3500, a flexible printed circuit board 2200, and a housing 2100 assembled together in a closed and an open state according to some embodiments of the present utility model. In some embodiments, the wire management mechanism 3000 further includes a wire take-up device 3500 disposed on the lower housing 2120. As shown in fig. 10, the flexible printed circuit board 2200 passes through the first tube 3100 and the second tube 3200 rotatable with respect to the housing 2100, leaves the rotary shaft cover 2130 from the outlet L and enters the lower housing 2120. After the flexible printed circuit board 2200 enters the lower case 2120, it is finally electrically connected to the printed circuit board assembly 2400 through the wire takeup device 3500 and the supporter 2300. During the repeated opening and closing of the upper housing 2110, the position of the outlet L of the flexible printed circuit board 2200 hardly changes, and the height difference δ is significantly reduced so that the height difference δ approaches zero. In this way, the risk of breakage of the flexible printed circuit board 2200 due to repeated bending is reduced, and the movement stroke required for the wire takeup device 3500 is reduced, which is advantageous for the miniaturization of the mechanism. The detailed construction of the take-up 3500 will be described below.

Fig. 11 illustrates a bottom perspective view of the spooling device 3500 assembled within the lower housing 2120, wherein the outer wall of the lower housing 2120 is omitted to clearly show the internal configuration, in accordance with some embodiments of the utility model. As can be seen from fig. 10 and 11, the wire take-up device 3500 is disposed on one side of the lower housing 2120 near the rotating shaft cover 2130, and does not occupy the volume of the lower housing 2120 in the thickness direction, which is beneficial to the light and thin mechanism and to release more space for other components. As shown in fig. 11, the take-up 3500 is secured to the printed circuit board assembly 2400 by a plurality of bolts 2450. In some embodiments, a support 2300 may be secured to the take-up 3500 side by a plurality of bolts 2350. In embodiments where the electronic device 2000 includes the support member 2300, the support member 2300 may provide further receiving space for the flexible printed circuit board 2200. As shown, the flexible printed circuit board 2200, after passing through the take-up 3500, may be wound through the support member 2300 and then electrically connected to the printed circuit board assembly 2400 via one or more connectors.

Please refer to fig. 12A, 12B and 13. Fig. 12A, 12B and 13 illustrate front, top and exploded views, respectively, of a take-up 3500, in accordance with some embodiments of the utility model. As shown in the drawing, the wire winding device 3500 mainly includes a fixing portion 3510, a winding rod 3520, and a plurality of second elastic elements 3530. As described above, the fixing portion 3510 may be fixed to the printed circuit board assembly 2400 by a plurality of bolts 2450. Since the printed circuit board assembly 2400 is fixed inside the housing 2100, the fixing portion 3510 is indirectly fixedly coupled to the housing 2100. The winding rod 3520 can slide relative to the fixing portion 3510, for example: along the vertical direction in fig. 12B. The plurality of second elastic members 3530 provide an elastic restoring force that the winding rod 3520 slides with respect to the fixing portion 3510. The winding rod 3520 is slidably connected to the fixing portion 3510 through a plurality of second elastic members 3530.

In detail, as shown in fig. 12B, the fixing portion 3510 includes a rod-shaped structure 3511, and the winding rod 3520 includes a rod-shaped structure 3521. The rod-like structures 3511 and 3521 are parallel to each other. The extending directions of the rod-shaped structures 3511 and 3521 are parallel to the extending direction of the first extending portion 3120 of the first tube 3100 and also parallel to the extending direction of the second extending portion 3220 of the second tube 3200.

As shown in fig. 13, the fixing portion 3510 further includes a plurality of fixing pins 3513. Each fixing pin 3513 corresponds to a respective one of the second elastic elements 3530. The winding rods 3520 each include an opening 3525 at opposite ends of the rod-like structure 3521. Two opposite fixing pins 3513 respectively pass through each of the openings 3525 and each of the second elastic elements 3530. And, each of opposite ends of the rod-shaped structure 3511 of the fixing portion 3510 includes a receiving portion 3515. The two opposite receiving portions 3515 respectively receive the second elastic element 3530, the opening 3525 of the winding rod 3520, and the fixing pin 3513 passing through the second elastic element 3530 and the opening 3525.

When the flexible printed circuit board 2200 surrounds the winding rod 3520, the flexible printed circuit board 2200 drives the winding rod 3520 to approach or separate from the rod-shaped structure 3511 of the fixing portion 3510 along with the opening/closing of the upper housing 2110, thereby achieving the functions of winding and unwinding. For example (referring to fig. 10), when the upper housing 2110 is in the closed state, the flexible printed circuit board 2200 tightens the winding rod 3520 toward the rod-shaped structure 3511, and the second elastic element 3530 is compressed. When the upper housing 2110 is opened, the flexible printed circuit board 2200 is released, and at this time, the elastic restoring force of the second elastic member 3530 moves the winding rod 3520 away from the rod-shaped structure 3511, and returns to the original position. It should be noted that, since the height of the outgoing line L of the flexible printed circuit board 2200 is kept constant by using the first tube 3100, the second tube 3200 and the first elastic member 3300, the stroke length required for the winding rod 3520 is significantly smaller than that of the conventional wire winding device, for example: the stroke length required by the conventional wire-rewinding device may be greater than 5 mm, and the stroke length required by the wire-rewinding device 3500 disclosed in the present application may be less than 3 mm.

Please refer to fig. 11, 13, 14A and 14B. Fig. 14A and 14B are schematic views illustrating an assembling process of the take-up 3500 according to some embodiments of the utility model, wherein an outer wall of the lower housing 2120 is omitted to clearly show an internal structure. The assembled take-up 3500 is shown in fig. 11.

First, the fixing pin 3513, the winding rod 3520, and the second elastic element 3530 are assembled into the receiving portion 3515 of the fixing portion 3510 along the central axis direction of the both-side fixing pin 3513 shown in fig. 13.

Next, as shown in the left drawing of fig. 14A, the flexible printed circuit board 2200 may be extended into the lower housing 2120 after passing through the first tube 3100 and the second tube 3200. The openings 3517 on opposite sides of the securing portion 3510 are aligned with holes in the printed circuit board assembly 2400 in the direction of arrow F. The fixing portion 3510 is fixed to the printed circuit board assembly 2400 by passing two bolts 2450 through the openings 3517 and the printed circuit board assembly 2400, as shown in the right-hand side of fig. 14A.

In some embodiments, the flexible printed circuit board 2200 may be folded toward the direction in which the second tube 3200 is located, such that the flexible printed circuit board 2200 covers over the fixing portion 3510, as shown in the left drawing of fig. 14B. At this time, the holes on the supporter 2300 are aligned with the screw holes 3519 on opposite sides of the fixing portion 3510 in the direction of arrow G. The support member 2300 is fixed to the fixing portion 3510 by passing two bolts 2350 through the support member 2300 and the screw holes 3519, as shown in the right drawing of fig. 14B.

Finally, the flexible printed circuit board 2200 is folded away from the second tube member 3200 such that the flexible printed circuit board 2200 is covered over the support member 2300 and thereby electrically connects the printed circuit board assembly 2400 and/or one or more connection members therebetween, as shown in fig. 11.

In summary, by providing the wire arranging mechanism 3000 (e.g., at least including the first tube 3100, the second tube 3200 and the first elastic element 3300) according to the present utility model, the position of the wire outlet L of the flexible printed circuit board 2200 is hardly changed during the repeated opening and closing of the upper housing 2110 of the electronic device 2000, such that the height delta approaches zero. In this way, the risk of breakage of the flexible printed circuit board 2200 can be reduced, and the volume occupied by the wire-rewinding device 3500 can be reduced, which is beneficial to the light and thin mechanism.
