According to the claimed invention, the second holding casing has a front side and a rear side, and the rear side is coupled to the main casing. The pad structure has a plurality of engaging protrusions, and a cross section of each of the engaging protrusions gradually increases along a direction from the front side toward the rear side.
According to the claimed invention, the pad structure is made of rubber material.
According to the claimed invention, the main casing has a fixing rib. The second holding casing is rotably disposed on the main casing and has an abutting rib. The mechanism device further includes a driving member with a fixing end and a free end. The fixing end abuts against the fixing rib and the free end abutting against the abutting rib, such that the driving member drives the second holding casing to rotate toward the first holding casing, so as to make the pad structure press the upper surface of the electronic device.
According to the claimed invention, the mechanism device further includes a rotating arm rotably disposed on the frame. The rotating arm drives the second holding casing to rotate away from the first holding casing when the holding base rotates to a detaching position, so as to activate the pad structure to depart from the upper surface of the electronic device.

Please refer to FIG. 1. FIG. 1 is a schematic diagram of a display device 3000 according to a first embodiment of the present invention. As shown in FIG. 1, the display device 3000 includes a frame 1, a display unit 2 and a mechanism device 3. The display unit 2 and the mechanism device 3 are installed on the frame 1. The frame 1 is used for supporting the display unit 2 and the mechanism device 3 on a supporting surface (not shown in figures), such as a desktop, a ground and so on. The mechanism device 3 is used for coupling the display unit 2 to an electronic device 4, such that the display unit 2 displays an interface of the electronic device 4 for allowing the user to deal with the desired affairs executed by the electronic device 4 by utilizing the display unit 2. In this embodiment, the display unit 2 is a liquid crystal display module, such as a liquid crystal monitor, a liquid crystal television and so on, and the electronic device 4 is a portable electronic device, such as a tablet computer and so on.
Please refer to FIG. 1 to FIG. 3. FIG. 2 is an exploded diagram of the frame 1 and the mechanism device 3 according to the first embodiment of the present invention. FIG. 3 is a partly exploded diagram of the frame 1 and the mechanism device 3 according to the first embodiment of the present invention. As shown in FIG. 1 to FIG. 3, the mechanism device 3 includes a hinge mechanism 30, a holding base 31, two guiding members 32, two fixing members 33 and a connector 34. The hinge mechanism 30 is installed on the frame 1. The holding base 31 is pivoted to the frame 1 by the hinge mechanism 30, such that the holding base 31 is able to pivot relative to the frame 1. Furthermore, the holding base 31 includes a main casing 311, a first holding casing 312 and a second holding casing 313. The first holding casing 312 and the second holding casing 313 extend from two opposite sides of the main casing 311 along a direction away from the hinge mechanism 30. Accordingly, the main casing 311, the first holding casing 312 and the second holding casing 313 cooperatively define a clamping slot 314 with openings formed on two sides thereof, such that the holding base 31 holds the electronic device 4 by utilizing the clamping slot 314.
It should be noticed that since the openings are formed on the two sides of the clamping slot 314 on the holding base 31 of the present invention, the openings on the two sides of the clamping slot 314 do not constrain a width of the electronic device 4 that is held by the clamping slot 314. In other words, the holding base 31 of the present invention is able to hold electronic devices with different sizes by design of the clamping slot 314 with the openings formed on the two sides thereof. Furthermore, the two guiding members 32, the two fixing members 33 and the connector 34 are all disposed inside the clamping slot 314, and the connector 34 is coupled to the display unit 2. Those amounts and configuration of the guiding member 32 and the fixing member 33 are not limited to those illustrated in figures in this embodiment. The mechanism device 3 can include one guiding member 32 and one fixing member 33 as well, and it depends on practical demands.
Please refer to FIG. 3 to FIG. 5. FIG. 4 is a diagram of the frame 1 and the mechanism device 3 in a detaching status according to the first embodiment of the present invention. FIG. 5 is a diagram of the frame 1 and the mechanism device 3 in a usage status according to the first embodiment of the present invention. As shown in FIG. 3 to FIG. 5, the two guiding members 32 are respectively a guiding post, and the two fixing members 33 are respectively a bushing structure covering the guiding post (i.e. the guiding member 32). In this embodiment, the hinge mechanism 30 includes a base 301 and a rotating member 302. The rotating member 302 is pivoted to the base 301, and the base 301 is fixed on the frame 1 for providing foundation that the rotating member 302 is able to pivot relative to the frame 1. The guiding post protrudes from the rotating member 302 and the holding base 31 and the connector 34 are both installed on the rotating member 302. Accordingly, the guiding post, the holding base 31 and the connector 34 are able to be activated to rotate relative to the frame 1 with the rotating member 302 simultaneously. In addition, three through holes 315 are formed on the main casing 311 of the holding base 31, wherein the through holes 315 on two lateral sides of the main casing 311 are circular holes for allowing the guiding posts to pass through and dive into the clamping slot 314; the through hole 315 in the middle of the main casing 311 is a rectangular hole for allowing the connector 34 to pass through and dive into the clamping slot 314.
Furthermore, guiding post (i.e. the guiding member 32) has a front end 321 and a rear end 322. During assembly, the guiding post passes through the main casing 311 along a direction from the rear end 322 toward the front end 321 (i.e. a first direction X1). In addition, the bushing structure (i.e. the fixing member 33) has a plurality of engaging protrusions 331. A cross section of each of the engaging protrusions 331 gradually increases along a direction from the front end 321 toward the rear end 322 (i.e. a second direction X2). In other words, each of the engaging protrusions 331 is substantially a triangular structure, as shown in FIG. 4. In this embodiment, the bushing structure (i.e. the fixing member 33) is made of rubber material (e.g. carbon rubber material).
As shown in FIG. 4 and FIG. 5, when the mechanism device 3 is desired to couple the electronic device 4 to the display unit 2, the electronic device 4 is inserted into the clamping slot 314 on the holding base 31, which is in a detaching position shown in FIG. 4, along the second direction X2. During the aforesaid process, the guiding post (i.e. the guiding member 32) is able to insert into a guiding hole 41 on the electronic device 4, such that the electronic device 4 is guided from a position represented by solid lines to a position represented by dash lines, as shown in FIG. 4. In other words, the guiding member 32 is used for guiding the electronic device 4 to enter the clamping slot 314 by the aforesaid cooperation of the guiding post and the guiding hole 41, such that the holding base 31 is able to hold the electronic device 4.
It should be noticed that a length L of the guiding member 32 can be designed to be greater than a width W of the second holding casing 313 of the holding base 31 for the sake of facilitating the guiding hole 41 on the electronic device 4 to be aligned with the guiding post inside the clamping slot 314. Accordingly, the connector 34 is able to exceed an area covered by the second holding casing 313 for enabling a user to see the front end 321 of the guiding member 32 from a side above holding base 31. It facilitates the guiding hole 41 on the electronic device 4 to be aligned with the guiding post (i.e. the guiding member 32), so as to smoothly guide and properly orient the electronic device 4 into the clamping slot 314. In such a manner, a connector (not shown in figures) of the electronic device 4 is able to be aligned with the connector 34 properly during the aforesaid process, so as to prevent the connector 34 of the mechanism device 3 and the connector of the electronic device 4 from damage due to improper alignment.
Furthermore, since an outer diameter of the bushing structure (i.e. the fixing member 33) is slightly greater than a bore diameter of the guiding hole 41 and the bushing structure is made of flexible material (e.g. the rubber material), the bushing structure (i.e. the fixing member 33) is compressed by a wall 410 surrounding the guiding hole 41 and thus it leads the bushing structure to tightly fit the wall 410 surrounding the guiding hole 41 during the process that the guiding post (i.e. the guiding member 32) inserts into the guiding hole 41. In other words, for the sake of the wall 410 surrounding the guiding hole 41 compressing the bushing structure (i.e. the fixing member 33), the fixing member 33 is able to fix the electronic device 4 inside the clamping slot 314 when the electronic device 4 enters the clamping slot 314, so as to prevent the electronic device 4 from detaching from the clamping slot 314.
In addition, since the cross section of the engaging protrusion 331 of the bushing structure (i.e. the fixing member 33) gradually increases along the direction from the front end 321 toward the rear end 322 (i.e. the second direction X2), i.e. a direction, which the cross section of the engaging protrusion 331 increases, is reverse to a detaching direction that the electronic device 4 detaches from the mechanism device 3 (i.e. the first direction X1). As a result, it facilitates to increase resistance of the guiding hole 41 on the electronic device 4 detaching from the fixing member 33 of the mechanism device 3 that the cross-section increasing direction of the engaging protrusion 331 is reverse to the detaching direction that the electronic device 4 detaches from the mechanism device 3 (i.e. the first direction X1). Accordingly, the fixing member 33 fits the wall 410 surrounding the guiding hole 41 more tightly. As mentioned above, the engaging protrusion 331 with reverse structure of the present invention enables the electronic device 4 to fix inside the clamping slot 314 more stably.
In summary, when the holding base 31 holds the electronic device 4, the weight of the electronic device 4 itself drives the holding base 31 to rotate relative to the frame 1, such that the electronic device 4 and the holding base 31 rotate relative to the frame 1 to a usage position, as shown in FIG. 5. Meanwhile, a side of the electronic device 4 is supported by a supporting surface 1000, such that an angle θ is included between the electronic device 4 and the supporting surface 1000 for adjusting an angle between the electronic device 4 and the user, leading to convenience of operation of the electronic device 4.
Please refer to FIG. 6, FIG. 7A and FIG. 7B. FIG. 6 is an assembly diagram of a mechanism device 3′ and the frame 1 according to a second embodiment of the present invention. FIG. 7A is an exploded diagram of the mechanism device 3′ and the frame 1 according to the second embodiment of the present invention. FIG. 7B is a partly exploded perspective diagram of the mechanism device 3′ and the frame 1 according to the second embodiment of the present invention. As shown in FIG. 6, FIG. 7A and FIG. 7B, the main difference between the mechanism device 3′ and the aforesaid mechanism device 3 is that a guiding member 32′ of the mechanism device 3′ is a first magnetic member disposed on the first holding casing 312 of a holding base 31′, and a fixing member 33′ of the mechanism device 3′ is a pad structure disposed on a second holding casing 313′ of the holding base 31′. The main casing 311 of the holding base 31′ has a fixing rib 3110. The second holding casing 313′ is rotably disposed on the main casing 311 and has an abutting rib 3130. The mechanism device 3′ further includes a driving member 35. In this embodiment, the driving member 35 is a torsion spring with a fixing end 351 and a free end 352. The fixing end 351 abuts against the fixing rib 3110, and the free end 352 abuts against the abutting rib 3130. Accordingly, the driving member 35 (i.e. the torsion spring) is able to drive the second holding casing 313′ to rotate toward the first holding casing 312. In other words, the driving member 35 of the mechanism device 3′ is used for driving the second holding casing 313′ to rotate along a first rotating direction R1, as shown in FIG. 6.
Please refer to FIG. 7A, FIG. 8 and FIG. 9. FIG. 8 is a diagram of the mechanism device 3′ and the frame 1 in a detaching status according to the second embodiment of the present invention. FIG. 9 is a diagram of the mechanism device 3′ and the frame 1 in a usage status according to the second embodiment of the present invention. As shown in FIG. 7A, FIG. 8 and FIG. 9, the second holding casing 313′ has a front side 3131 and a rear side 3132. The rear side 3132 is coupled to the main casing 311. The pad structure (i.e. the fixing member 33′) has a plurality of engaging protrusions 331′. A cross section of each of the engaging protrusions 331′ gradually increases along a direction from the front side 3131 toward the rear side 3132 (i.e. the second direction X2). In other words, each of the engaging protrusions 331′ is substantially a triangular structure, as shown in FIG. 8. In this embodiment, the pad structure (i.e. the fixing member 33′) is made of rubber material (e.g. the carbon rubber material).
As shown in FIG. 8 and FIG. 9, when the mechanism device 3′ is desired to couple the electronic device 4 to the display unit 2, the electronic device 4 is inserted into the clamping slot 314 on the holding base 31′ in a detaching position, as shown in FIG. 8, along the second direction X2. During the aforesaid process, the first magnetic member (i.e. the guiding member 32′) is able to abstract a second magnetic member 42 of the electronic device 4, such that the electronic device 4 is guided from a position shown in FIG. 8 to a position shown in FIG. 9. In other words, the guiding member 32′ is used for guiding the electronic device 4 to enter the clamping slot 314 by the aforesaid cooperation of the first magnetic member (i.e. the guiding member 32′) and the second magnetic member 42, such that the holding base 31′ is able to hold the electronic device 4.
It should be noticed that a length L′ of the guiding member 32′ can be designed to be greater than a width W′ of the second holding casing 313′ of the holding base 31′ for the sake of facilitating the electronic device 4 to be aligned with the first magnetic member inside the clamping slot 314. Accordingly, the guiding member 32′ is able to exceed an area covered by the second holding casing 313′ for enabling a user to see the guiding member 32′ from a side above the holding base 31′. It facilitates the electronic device 4 to be aligned with the first magnetic member (i.e. the guiding member 32′), so as to smoothly guide and properly orient the electronic device 4 into the clamping slot 314. In such a manner, a connector 43 of the electronic device 4 is able to be aligned with the connector 34 properly during the aforesaid process, so as to prevent the connector 34 of the mechanism device 3′ and the connector 43 of the electronic device 4 from damage due to improper alignment.
Furthermore, since the pad structure (i.e. the fixing member 33′) is made of rubber material, the driving member 35 drives the second holding casing 313′ to rotate along the first rotating direction R1 to press the upper surface of the electronic device 4. It leads the pad structure to resiliently abut against the electronic device 4 when the electronic device 4 is guided into the clamping slot 314. In other words, for the sake of the pad structure (i.e. the fixing member 33′) resiliently abutting against the electronic device 4, the fixing member 33′ is able to fix the electronic device 4 inside the clamping slot 314 when the electronic device 4 enters the clamping slot 314, so as to prevent the electronic device 4 from detaching from the clamping slot 314.
Please refer to FIG. 10A, FIG. 10B and FIG. 10C. FIG. 10A is an exploded diagram of a mechanism device 3′′ and the frame 1 according to a third embodiment of the present invention. FIG. 10B is a partly exploded diagram of the mechanism device 3′′ and the frame 1 in another view according to the third embodiment of the present invention. FIG. 10C is a partly exploded perspective diagram of the mechanism device 3′′ and the frame 1 according to the third embodiment of the present invention. As shown in FIG. 10A, FIG. 10B and FIG. 10C, the main difference between the mechanism device 3′′ and the aforesaid mechanism device 3′ is that the mechanism device 3′′ further includes a rotating arm 36 rotably disposed on the frame 1, a main casing 311′ of a holding base 31′′ further has a pushing block 3111, and a second holding casing 313′′ of the mechanism device 3′′ further has a pushed structure 3133. In addition, the rotating arm 36 has a pivotal end 361 and an abutting end 362. The pivotal end 361 is pivoted to the frame 1.
Please refer to FIG. 11 and FIG. 12. FIG. 11 is a diagram of the frame 1 and the mechanism device 3′′ in a detaching status according to the third embodiment of the present invention. FIG. 12 is a diagram of the frame 1 and the mechanism device 3′′ in a usage status according to the third embodiment of the present invention. As shown in FIG. 11 and FIG. 12, during the frame 1 and the mechanism device 3′′ is rotated from a usage position shown in FIG. 12 to a detaching position shown in FIG. 11, the pushed structure 3133 of the second holding casing 313′′, the pushed structure 3133 of the second holding casing 313′′ is moved from a position shown in FIG. 12 to a position where the pushed structure 3133 abuts against the abutting end 362 of the rotating arm 36, and the pushing block 3111 of the main casing 311′ is moved from a position shown in FIG. 12 to a position where the pushing block 3111 pushes the rotating arm 36. Accordingly, when the frame 1 and the mechanism device 3′′ further moves to the detaching position shown in FIG. 11, the pushing block 3111 pushes the rotating arm 36, so as to activate the abutting end 362 to push the pushed structure 3133. In such a manner, the rotating arm 36 is able to drive the second holding casing 313′′ to rotate away from the first holding casing 312 and toward the detaching position shown in FIG. 11, so as to activate the pad structure (i.e. the fixing member 33′) to depart from an upper surface of the electronic device 4. As a result, the second holding casing 313′′ and the pad structure (i.e. the fixing member 33′) is no longer press the upper surface of the electronic device 4, so as to be able to detach the electronic device 4 from the clamping slot 314 on the holding base 31′′.
On the other hand, during the frame 1 and the mechanism device 3′′ is rotated from the detaching position shown in FIG. 11 to the usage position shown in FIG. 12, the pushing block 3111 of the main casing 311′ departs from the rotating arm 36. Accordingly, the pushing block 3111 is no longer push the rotating arm 36, and thus the rotating arm 36 falls due to attraction by gravity itself. As a result, the abutting end 362 of the rotating arm 36 releases the pushed structure 3133 of the second holding casing 313′′. In such a manner, the frame 1 and the mechanism device 3′′ is able to move toward the usage position shown in FIG. 12. Meanwhile, the driving member 35 (as shown in FIG. 10A) of the mechanism device 3′′ drives the second holding casing 313′′ to rotate toward the first holding casing 312, such that the second holding casing 313′′ and the pad structure (i.e. the fixing member 33′) presses the upper surface of the electronic device 4, so as to fix the electronic device 4 inside the clamping slot 314 on the holding base 31′′.
Compared to the prior art, the present invention utilizes the guiding member for properly orienting and guiding the electronic device into the clamping slot on the holding base. In such a manner, the connector of the electronic device is able to be aligned with the connector of the mechanism device properly during the aforesaid process, so as to prevent the connector of the mechanism device and the connector of the electronic device from damage due to improper alignment. Furthermore, when the electronic device is guided into the clamping slot on the holding base, the present invention further utilizes the fixing member to fix the electronic device inside the clamping slot, so as to prevent the electronic device from detaching from the clamping slot. Thus, it further prevents the connectors from improper mating. In addition, since the clamping slot for holding the electronic device has the openings formed on the two sides thereof, the openings on the two sides of the clamping slot do not constrain a width of the electronic device that is held by the clamping slot. In other words, the holding base of the present invention is able to hold electronic devices with different sizes by design of the clamping slot with the openings formed on the two sides thereof.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
