Description

TECHNICAL FIELD

[0001] The present invention relates to a connecting device, in particular, a telescopic connecting device. BACKGROUND

[0002] With the advancement of technology, currently, tablet computers (such as smart phones or tablet computers) have become common electronic devices for modern people. In order to protect or further expand the functions of the tablet computer, the user will connect the expansion device (such as a protective cover or a keyboard) to the tablet computer for use.

[0003] Generally, a flexible sheet is often used as a connecting element between the tablet computer and the expansion device, so that the tablet computer can be rotated relative to the expansion device through the flexible sheet to perform expansion or closing actions. However, since the length of the flexible sheet is fixed, whether the tablet computer and the expansion device are in an expanded or closed state, the overall exposed flexible sheet can be clearly seen. For example, when the tablet computer and the expansion device are in a closed state, the flexible sheet is bent into a U shape and protrudes from one side of the expansion device, which affects the overall aesthetics and the flexible sheet is easily damaged by external friction or pulling. SUMMARY

[0004] In view of the above, in one embodiment, a telescopic connecting device for connecting an electronic device is provided, the telescopic connecting device includes a base plate, a movable member, a flexible sheet, a device connecting member, and a plurality of elastic members. The movable member is arranged on the base plate, and the movable member can slide relative to the base plate along a movement direction. The flexible sheet has opposite first and second sides, and the first side is fixed to the movable member. The device connecting member is connected to the second side of the flexible sheet. The plurality of elastic members are arranged between the movable member and the base plate and are spaced apart from each other, and each elastic member generates an elastic pulling force on the movable member towards the base plate.

[0008] In another embodiment, each elastic member is a torsion spring, the movable member has a plurality of sliding grooves, the first end of each elastic member is fixed to the base plate, and the second end of each elastic member is slidably connected to each sliding groove of the movable member.

[0009] In another embodiment, the first guide is provided on the base plate, the second guide is provided on the movable member, the first guide and the second guide extend along the moving direction, and the second guide is slidably connected to the first guide.

[0010] In another embodiment, the base plate has a first limiting slot and opposite first and second plate sides, the first limiting slot is adjacent to the first plate side, the first limiting slot has a first side surface and a second side surface, the first side surface is adjacent to the first plate side relative to the second side surface, the movable member has a first limiting plate, the first limiting plate is located in the first limiting slot, the first limiting plate has a first side edge and a second side edge, the first side edge is adjacent to the first plate side relative to the second side edge, and the distance between the first side edge and the first side surface is smaller than the distance between the second side edge and the second side surface.

[0011] In another embodiment, the telescopic connecting device further comprises a plurality of swing rods, each swing rod has opposite pivot connection end and sliding end, the pivot connection end is pivotally arranged on the base plate, the sliding end is slidably connected to the movable member, the first end of each elastic member is fixed to the base plate, and the second end of each elastic member is fixed between the pivot connection end and the sliding end of each swing rod.

[0014] In summary, the flexible sheet of the telescopic connecting device is connected to the base plate through the movable member and the plurality of elastic members, so that the flexible sheet can be telescopically moved relative to the base plate. Therefore, when the telescopic connecting device is assembled with the electronic device and the expansion device, the length of the flexible sheet exposed from the electronic device and the expansion device can be greatly shortened, regardless of whether the electronic device and the expansion device are in an unfolded state, a closed state or other use states, thereby achieving the effects of increasing the appearance and preventing the flexible sheet from being damaged.

In addition, for convenience and clarity of explanation, the thickness or size of each element in the drawings is exaggerated, omitted, or schematically represented to facilitate understanding and reading by those skilled in the art. The dimensions of each element are not necessarily their actual dimensions and are not intended to limit the conditions under which the present invention can be implemented. Therefore, they have no substantive technical significance. Any structural modifications, changes in proportional relationships, or adjustments in size, without affecting the efficacy and objectives of the present invention, shall still fall within the scope of the technical content disclosed in the present invention. The same reference numerals will be used throughout the drawings to represent the same or similar elements.

[0080] Figure 1 FIG. 1 is a schematic diagram of the application of the first embodiment of the telescopic connection device of the present invention.Figure 1 As shown, the telescopic connection device 1 of the embodiment of the present invention is used to assemble an electronic device 2 (such as a smartphone or tablet computer), so that the electronic device 2 is connected to the expansion device 3, and the electronic device 2 can be rotated relative to the expansion device 3 to expand or close each other. For example, the expansion device 3 can include at least one of a protective cover, a protective plate, a keyboard, or a touch panel, such as Figure 1 As shown, in this embodiment, the expansion device 3 includes an input unit 4 of the electronic device 2 (here, the input unit 4 includes a keyboard 4 a and a touch panel 4 b ). The user can control the electronic device 2 through the input unit 4 to input information.

[0081] Figure 2 This is a perspective view of a first embodiment of the telescopic connection device of the present invention. Figure 3 This is an exploded perspective view of the first embodiment of the telescopic connection device of the present invention. Figure 4 This is a partially enlarged exploded perspective view of the first embodiment of the telescopic connection device of the present invention. Figure 5 This is a plan view of a first embodiment of the telescopic connection device of the present invention. Figure 6 This is a diagram showing the expansion and contraction of the flexible piece of the first embodiment of the telescopic connection device of the present invention. Figures 2 to 6 As shown, in the first embodiment, the telescopic connection device 1 includes a base plate 10 , a movable member 20 , a flexible sheet 30 , a device connection member 40 and a plurality of elastic members 50 .

[0082] like Figures 1 to 6 As shown, the base plate 10 can be a long strip plate, and the telescopic connecting device 1 can be connected to the expansion device 3 to form an input device 5 (such as Figure 1 ), wherein the base plate 10 can be assembled with the expansion device 3. For example, the base plate 10 can be connected to the input unit 4 of the expansion device 3, but this is not limited to this. In some embodiments, the base plate 10 can also be a part of the expansion device 3, for example, the base plate 10 can be a plate of a protective cover, or the base plate 10 can also be part of the outer shell of the expansion device 3.

[0083] like Figures 2 to 6 As shown, the movable member 20 is a long bar or plate and is disposed on the substrate 10, and the movable member 20 can move relative to the substrate 10 along the moving direction S (such as Figure 5 and Figure 6 In this embodiment, the moving direction S is perpendicular to the extending direction of the substrate 10 and the extending direction of the movable member 20, but this is not limited.

[0084] like Figures 2 to 6As shown, in the present embodiment, the substrate 10 has a concave space 14, and the movable member 20 is disposed in the concave space 14 of the substrate 10. In addition, the substrate 10 has at least one first guide 11, which is a guide rib in the present embodiment, and the first guide 11 is in plurality and is spaced apart from each other. The movable member 20 has a second guide 22, which is a guide groove in the present embodiment, and the number and position of the second guide 22 correspond to the number and position of the first guide 11. The first guide 11 and the second guide 22 extend along the above-mentioned moving direction S, and each second guide 22 is slidably connected to each first guide 11, so that the movable member 20 can be guided by the first guide 11 and the second guide 22 to move more stably relative to the substrate 10 and is less likely to shake or deviate. However, the above-mentioned embodiment is only an example, and in some embodiments, the structure of the first guide 11 and the second guide 22 can also be inversed, for example, the first guide 11 can be a guide groove, and the second guide 22 can be a guide rib.

[0085] As shown, Figures 2 to 6 The flexible sheet 30 is made of a flexible material, such as soft materials such as leather, silicone or plastic, so that the flexible sheet 30 can be freely bent when subjected to force. The flexible sheet 30 has opposite first and second sides 31 and 32, and the first side 31 is fixed to the movable member 20, so that the local area of the flexible sheet 30 close to the first side 31 is located in or on the substrate 10. Since the flexible sheet 30 is connected to the movable member 20, the flexible sheet 30 can slide relative to the substrate 10 along the above-mentioned moving direction S to move away from or approach the substrate 10 when subjected to force. In some embodiments, the first side 31 of the flexible sheet 30 can be connected and fixed to the movable member 20 by locking, clamping or adhesion, but this is not limited.

[0086] As shown, Figure 2 and Figure 3 In the present embodiment, the telescopic connecting device 1 can include a cover 18 fixed to the substrate 10 to form a containing space between the cover 18 and the substrate 10, and the movable member 20 and the first side 31 of the flexible sheet 30 can be disposed in the containing space between the cover 18 and the substrate 10, so that the first side 31 of the flexible sheet 30 is kept between the cover 18 and the substrate 10. In some embodiments, the cover 18 can also be a part of the expansion device 3, for example, the cover 18 can be a partial housing of the expansion device 3.

[0087] As shown, Figures 2 to 6As shown, the device connector 40 is connected to the second side 32 of the flexible sheet 30 and is used to assemble the electronic device 2. In some embodiments, the device connector 40 can be a rod or a plate, and the electronic device 2 and the device connector 40 can be connected to each other by snapping, interlocking, or magnetic attraction.

[0088] like Figures 2 to 6 As shown, in this embodiment, the device connector 40 is a rod, and the flexible sheet 30 is partially covered and fixed to the outside of the device connector 40 near the second side 32 to increase the aesthetics. The device connector 40 may be provided with a magnetic element so that the electronic device 2 can be adsorbed on the device connector 40 and connected to the flexible sheet 30. In addition, in this embodiment, the device connector 40 has an electrical connector 41 (such as Figure 2 As shown, the electrical connector 41 may be a universal serial bus (USB) or a pogo pin connector. The electrical connector 41 may be electrically connected to the input unit 4 and may be plugged into the electronic device 2, thereby further stabilizing the connection between the electronic device 2 and the device connector 40. The electronic device 2 may also be electrically connected to the input unit 4 via the electrical connector 41, allowing the input unit 4 to be used to control the electronic device 2 and input information. However, the above embodiment is merely exemplary. In some embodiments, the electronic device 2 and the input unit 4 may be connected via wireless communication, thereby omitting the electrical connector 41 from the device connector 40.

[0089] like Figures 2 to 6 As shown, a plurality of elastic members 50 are located between the movable member 20 and the base plate 10 and are spaced apart from each other. Each elastic member 50 has elastic expansion and contraction capabilities. That is, each elastic member 50 can be deformed when subjected to an external force and can return to its original shape after the external force is removed. In this embodiment, each elastic member 50 has a first end 51 and a second end 52. The first end 51 is connected to the base plate 10, and the second end 52 is connected to the movable member 20. In this way, as shown in FIG. Figure 5 and Figure 6 As shown, when the flexible sheet 30 is pulled and moves outward in a direction away from the substrate 10, the movable member 20 can drive each elastic member 50 to deform (such as Figure 6 As shown, each elastic member 50 is a tension spring and is stretched and deformed), so that each elastic member 50 generates an elastic pulling force on the movable member 20 toward the substrate 10. When the flexible sheet 30 is released and the external force is removed, the elastic pulling force can drive the flexible sheet 30 to move back toward the substrate 10, so that each elastic member 50 returns to its original state (as shown in FIG. Figure 5 shown).

Figure 2 is a perspective view of the flexible sheet retracting device of Figure 1 in use. Figure 1 As shown in Figure 2, when the electronic device 2 and the expansion device 3 are in an unfolded state, most of the flexible sheet 30 can be retracted into the base plate 10 or the expansion device 3, or, during the unfolding of the electronic device 2 on the expansion device 3, the user can exert force to pull the flexible sheet 30 out of the base plate 10 or the expansion device 3 to facilitate the rotation of the electronic device 2, and then, as shown in Figure 3, when the electronic device 2 and the expansion device 3 are in a folded state, the elastic members 50 can pull the excess portion of the flexible sheet 30 back into the base plate 10 or the expansion device 3, greatly reducing the length of the flexible sheet 30 exposed to the base plate 10 or the expansion device 3. Figure 7 As shown in Figure 2, when the electronic device 2 and the expansion device 3 are in an unfolded state, most of the flexible sheet 30 can be retracted into the base plate 10 or the expansion device 3, or, during the unfolding of the electronic device 2 on the expansion device 3, the user can exert force to pull the flexible sheet 30 out of the base plate 10 or the expansion device 3 to facilitate the rotation of the electronic device 2, and then, as shown in Figure 3, when the electronic device 2 and the expansion device 3 are in a folded state, the elastic members 50 can pull the excess portion of the flexible sheet 30 back into the base plate 10 or the expansion device 3, greatly reducing the length of the flexible sheet 30 exposed to the base plate 10 or the expansion device 3.

[0091] As shown in Figure 2, when the electronic device 2 and the expansion device 3 are in an unfolded state, most of the flexible sheet 30 can be retracted into the base plate 10 or the expansion device 3, or, during the unfolding of the electronic device 2 on the expansion device 3, the user can exert force to pull the flexible sheet 30 out of the base plate 10 or the expansion device 3 to facilitate the rotation of the electronic device 2, and then, as shown in Figure 3, when the electronic device 2 and the expansion device 3 are in a folded state, the elastic members 50 can pull the excess portion of the flexible sheet 30 back into the base plate 10 or the expansion device 3, greatly reducing the length of the flexible sheet 30 exposed to the base plate 10 or the expansion device 3. Figures 2 to 6 As shown in Figure 2, when the electronic device 2 and the expansion device 3 are in an unfolded state, most of the flexible sheet 30 can be retracted into the base plate 10 or the expansion device 3, or, during the unfolding of the electronic device 2 on the expansion device 3, the user can exert force to pull the flexible sheet 30 out of the base plate 10 or the expansion device 3 to facilitate the rotation of the electronic device 2, and then, as shown in Figure 3, when the electronic device 2 and the expansion device 3 are in a folded state, the elastic members 50 can pull the excess portion of the flexible sheet 30 back into the base plate 10 or the expansion device 3, greatly reducing the length of the flexible sheet 30 exposed to the base plate 10 or the expansion device 3.

[0096] As shown in the second embodiment, the telescopic connecting device la also comprises a base plate 10a, a movable member 20a, a flexible sheet 30, a device connecting member 40 and a plurality of elastic members 50.

Figures 8 to 11 As shown in the second embodiment, the telescopic connecting device la also comprises a base plate 10a, a movable member 20a, a flexible sheet 30, a device connecting member 40 and a plurality of elastic members 50. The movable member 20a is disposed on the base plate 10a, and the movable member 20a is slidable relative to the base plate 10a along the above-mentioned moving direction S. The first side 31 of the flexible sheet 30 is fixed to the movable member 20a. The device connecting member 40 is connected to the second side 32 of the flexible sheet 30. The first end 51 of each elastic member 50 is connected to the base plate 10a, and the second end 52 of each elastic member 50 is connected to the movable member 20a. Figure 8 As shown in the second embodiment, the telescopic connecting device la also comprises a base plate 10a, a movable member 20a, a flexible sheet 30, a device connecting member 40 and a plurality of elastic members 50. The movable member 20a is disposed on the base plate 10a, and the movable member 20a is slidable relative to the base plate 10a along the above-mentioned moving direction S. The first side 31 of the flexible sheet 30 is fixed to the movable member 20a. The device connecting member 40 is connected to the second side 32 of the flexible sheet 30. The first end 51 of each elastic member 50 is connected to the base plate 10a, and the second end 52 of each elastic member 50 is connected to the movable member 20a. Figure 11As shown, when the flexible sheet 30 is pulled and moves outward in a direction away from the substrate 10a, if the user applies improper force and causes the flexible sheet 30 to deflect toward the second plate side 13 of the substrate 10a (as shown in FIG. Figure 11 As shown by the arrow L in the figure, the first side edge 251 of the first limiting plate 25 and the first side surface 151 of the first limiting groove 15 can generate interference and friction to prevent the flexible sheet 30 from continuing to deflect, thereby correcting the moving trajectory of the flexible sheet 30 and enabling the flexible sheet 30 to be telescopically displaced in the above-mentioned active direction S.

[0097] For example Figures 8 to 11 As shown, the second limiting plate 26 and the second limiting groove 16 adjacent to the first plate side 12 may also have the same or similar structural design as the first limiting groove 15 and the first limiting plate 25 described above. That is, the second limiting plate 26 may be positioned relatively close to the side of the second limiting groove 16 adjacent to the first plate side 12. Thus, when the flexible sheet 30 deflects toward the second plate side 13 of the substrate 10a during extension and retraction, the first limiting plate 25 and the second limiting plate 26 adjacent to the first plate side 12 can work together to guide the movement trajectory of the flexible sheet 30, preventing the flexible sheet 30 from deflecting during extension and retraction. Similarly, the first limiting plate 25 adjacent to the second plate side 13 may be positioned relatively close to the side of the first limiting groove 15 adjacent to the second plate side 13, and the second limiting plate 26 adjacent to the second plate side 13 may be positioned relatively close to the side of the second limiting groove 16 adjacent to the second plate side 13, preventing the flexible sheet 30 from deflecting toward the first plate side 12 of the substrate 10a during extension and retraction.

Figure 13 This is a diagram showing the expansion and contraction of the flexible piece of the third embodiment of the telescopic connection device of the present invention. Figure 12 and Figure 13 As shown, the difference between this embodiment and the first embodiment mentioned above is at least that each elastic member 50b of the telescopic connection device 1b of this embodiment is a torsion spring, and the movable member 20b further has a plurality of slide grooves 21, and the plurality of slide grooves 21 are arranged at intervals from each other, and the first end 51b of each elastic member 50b is fixed to the base plate 10b. For example, in this embodiment, the base plate 10b has a plurality of fixing portions 17, and the plurality of fixing portions 17 are arranged at intervals from each other to respectively correspond to the plurality of elastic members 50b, and the first end 51b of each elastic member 50b is fixed to the corresponding fixing portion 17. The second end 52b of each elastic member 50b is slidably connected to each slide groove 21 of the movable member 20b. Thereby, when the flexible sheet 30 is pulled and moves outward in a direction away from the base plate 10b (such as Figure 13As shown in FIG. 6, when the flexible sheet 30 is pulled to move away from the base plate 10b, the movable member 20b can drive the second end 52b of each elastic member 50b to move away from the base plate 10b and slide along the sliding groove 21, so that each elastic member 50b is deformed by torsion to accumulate elastic force. When the external force is removed, each elastic member 50b can restore to the original state by the elastic force and drive the flexible sheet 30 to move towards the base plate 10b and retract (as shown in FIG. 7). Figure 12 As shown in FIG. 6, when the flexible sheet 30 is pulled to move away from the base plate 10b, the movable member 20b can drive the second end 52b of each elastic member 50b to move away from the base plate 10b and slide along the sliding groove 21, so that each elastic member 50b is deformed by torsion to accumulate elastic force. When the external force is removed, each elastic member 50b can restore to the original state by the elastic force and drive the flexible sheet 30 to move towards the base plate 10b and retract (as shown in FIG. 7).

[0101] Figure 19 This is a perspective view of a fifth embodiment of the telescopic connection device of the present invention. Figure 20 This is a partially enlarged perspective view of the fifth embodiment of the telescopic connection device of the present invention. Figure 21 This is a partially enlarged exploded perspective view of the fifth embodiment of the telescopic connection device of the present invention. Figure 22 is a cross-sectional view of a fifth embodiment of the telescopic connection device of the present invention, Figure 23 This is a diagram showing the expansion and contraction of the flexible piece of the fifth embodiment of the telescopic connection device of the present invention. Figures 19 to 23 As shown, in the fifth embodiment, the telescopic connection device 1d similarly includes a base plate 10d, a movable member 20d, a flexible sheet 30, a device connector 40, and a plurality of elastic members 50. This embodiment differs from the first embodiment in that the telescopic connection device 1d of this embodiment further includes at least one rolling member 65. In this embodiment, there are multiple rolling members 65, which are spaced apart from each other. Each rolling member 65 is rotatably connected to the movable member 20d, and the outer periphery of each rolling member 65 contacts the surface of the base plate 10d. In some embodiments, the rolling member 65 may be a needle roller, a ball roller, a roller, or other circular object.

[0102] By this, Figure 22 and Figure 23 As shown, when the flexible sheet 30 is subjected to force and stretches and contracts along the above-mentioned moving direction S, the movable part 20d and the substrate 10d can be in a rolling contact state through the arrangement of the above-mentioned multiple rolling parts 65, thereby greatly reducing the friction force and making the flexible sheet 30 move more smoothly.

[0103] In addition, if Figures 21 to 23 As shown, in this embodiment, one side of the base plate 10d further has a limiting protrusion 19, which is located between the rolling element 65 and the second side 32 of the flexible sheet 30. Thus, when the flexible sheet 30 is subjected to a force and moves away from the base plate 10d, the limiting protrusion 19 can prevent the flexible sheet 30 from being overstretched and prevent the movable member 20d from completely separating from the base plate 10d.

Any slight changes and modifications made by any person skilled in the art without departing from the spirit of the present invention should be included in the scope of the present invention.
