DETAILED DESCRIPTION OF DISCLOSED EMBODIMENTS
FIG. 4 is a schematic view illustrating a docking station and a portable electronic device before assembly according to an embodiment of the invention. FIG. 5 is a schematic cross-sectional view illustrating the region B depicted in FIG. 4. FIG. 6 is a schematic view illustrating the docking station and the portable electronic device depicted in FIG. 4 after assembly. FIG. 7 is a schematic cross-sectional view illustrating the region C in FIG. 6. With reference to FIG. 4 to FIG. 7, in the present embodiment, the docking station 200 serves to assemble the portable electronic device 60, and the portable electronic device 60 is, for instance, a tablet PC, a smart phone, or a personal digital assistant (PDA). The portable electronic device 60 has a display screen 62 and a slot 64. The docking station 200 includes a body 210, a pressing member 220, and an elastic member 230. The body 210 has a protrusion 211. The protrusion 211 is suitable for being lodged in the slot 64, such that the portable electronic device 60 and the docking station 200 are assembled to each other. The pressing member 220 is movably arranged in the protrusion 211. The elastic member 230 is located in the protrusion 211 and is in contact with the body 210 and the pressing member 220. Besides, the elastic member 230 constantly drives the pressing member 220 to move out of the protrusion 211 and to press against the inside of the slot 64 along a pressing direction D1. Here, the pressing direction D1 is perpendicular to the display screen 62.
In the present embodiment, the body 210 is made of metal, for instance. The body 210 includes a host 212 and a support member 213 that are pivoted to each other. Here, the host 212 is a keyboard module or any other add-ons, for instance. The protrusion 211 is located on the support member 213 and is capable of being lodged in the slot 64, such that the portable electronic device 60 can be held by a support surface 213a of the support member 213 and can rotate relative to the host 212 together with the support member 213. Thereby, the portable electronic device 60 may be folded on the host 212 or unfolded relative to the host 212. The user may also adjust the angle at which the portable electronic device 60 is unfolded relative to the host 212, so as to obtain an appropriate viewing angle.
The pressing member 220 is constituted by a rigid material, and the rigid material may be a metal material identical to that of the body 210. In general, a Teflon layer (not shown) may be placed on a surface of the pressing member 220 and a surface of the protrusion 211. Here, the Teflon layer is respectively formed on the surface of the pressing member 220 and the surface of the protrusion 211 by coating or adhesion, so as to reduce the abrasion caused by disassembling or assembling the portable electronic device 60 and the docking station 200.
With reference to FIG. 4 and FIG. 5, in the present embodiment, the docking station 200 further includes a screw locking member 240. The screw locking member 240 slides into the pressing member 220 and is locked to a threaded hole 211a of the protrusion 211, so as to assemble the pressing member 220 into a groove 211b of the protrusion 211. When the portable electronic device 60 is not assembled to the body 210, a portion of the pressing member 220 protrudes from the groove 211b. To be specific, the screw locking member 240 is a blunt bolt, and an outer diameter of the head 240a of the screw locking member 240 is greater than an inner diameter of the threaded hole 211a. Namely, when the elastic member 230 drives the pressing member 220 to move out of the protrusion 211, the head 240a of the screw locking member 240 stops the pressing member 220 and keeps the pressing member 220 to stay in the groove 211b, so as to prevent the pressing member 220 from being pushed by the elastic member 230 and then leaving the body 210.
The protrusion 211 further has a protruding pillar 211c located in the groove 211b, and the protruding pillar 211c is parallel to the support surface 213a of the support member 213 and is extended toward the pressing member 220. In the present embodiment, the elastic member 230 is a compression spring into which the protruding pillar 211c is inserted, for instance, so as to fix the relative positions of the elastic member 230 and the pressing member 220. As shown in FIG. 6 and FIG. 7, when the protrusion 211 is lodged in the slot 64, the elastic member 230 is further compressed, such that the pressing member 220 moves toward the inside of the groove 211b and is then hidden in the body 210. However, the pushing force of the elastic member 230 still drives the pressing member 220 to press against the inside of the slot 64 along the pressing direction D1. That is, through said configuration, after the portable electronic device 60 and the docking station 200 are assembled, the gap between the protrusion 211 and the slot 64 may be removed. Thereby, the portable electronic device 60 may be stably fixed to the support member 213 of the body 210, and the support stability of the docking station 200 may be significantly improved, so as to guarantee the favorable quality of using the portable electronic device 60.
FIG. 8 is a schematic partial cross-sectional view illustrating a docking station according to another embodiment of the invention. With reference to FIG. 8, in the present embodiment, the elastic member 230a is a rubber washer located in the groove 211b, for instance, so as to drive the pressing member 220 to move out of the protrusion 211. When the protrusion 210 is lodged in the slot 64, the elastic member 230a is compressed, such that the pressing member 220 may be hidden in the body 210. However, the elastic restoration force of the elastic member 230 may drive the pressing member 220 to press against the inside of the slot 64; further, the gap formed between the protrusion 211 and the slot 64 after the portable electronic device 60 and the docking station 200 are assembled may be removed, so as to achieve the same effects accomplished in the previous embodiment.
FIG. 9 is a schematic partial three-dimensional view illustrating a docking station according to yet another embodiment of the invention. FIG. 10 is a schematic cross-sectional view illustrating the region D depicted in FIG. 9. FIG. 11 is a schematic partial cross-sectional view illustrating the docking station and the portable electronic device depicted in FIG. 9 before assembly. FIG. 12 is a schematic partial cross-sectional view illustrating the docking station and the portable electronic device depicted in FIG. 11 after assembly. With reference to FIG. 9 to FIG. 12, in the present embodiment, the docking station 300 serves to assemble the portable electronic device 60, and the portable electronic device 60 has a display screen 62 and a slot 64. The docking station 300 includes a body 310, a pressing member 320, and an elastic member 330. The body 310 has a protrusion 311, a recess 312, and a sliding groove 313 that are adjacent to one another. The pressing member 320 is slidably pivoted to the sliding groove 313 and located in the recess 312. The elastic member 330 is in contact with the pressing member 320 and the body 310, and the elastic member 330 constantly drives the pressing member 320 to move into the recess 312. When the portable electronic device 60 enables the protrusion 311 to be inserted into the slot 64 along an assembling direction D2, the portable electronic device 60 presses against the pressing member 320 along the assembling direction D2, so as to drive the pressing member 320 to slide along the sliding groove 313, rotate, and move out of the recess 312. Besides, the pressing member 320 presses against the portable electronic device 60 along a pressing direction D3, such that the portable electronic device 60 is clamped by the pressing member 320 and the protrusion 311. Here, the assembling direction D2 is parallel to the display screen 62, and the pressing direction D3 is perpendicular to the display screen 64.
In the present embodiment, the body 310 is made of metal, for instance. The body 310 includes a host 314 and a support member 315 that are pivoted to each other. Here, the host 314 is a keyboard module or any other add-ons. Specifically, the support member 315 has a bottom surface 315a, and the protrusion 311 and the recess 312 are vertically arranged on the bottom surface 315a. The recess 312 faces the protrusion 311. The pressing member 320 is located between the recess 311 and the protrusion 312, the sliding groove 313 is located below the protrusion 311, and the protrusion 311 is lodged in the slot 64, such that the portable electronic device 60 is held by the support member 315 and rotates relative to the host 314 together with the support member 315.
According to the present embodiment, the protrusion 311 and the sliding groove 313 are parts of one structural member 340 that is assembled onto the bottom surface 315a; however, in another embodiment of the invention not shown in the drawings, the structural member and the support member 15 may be integrally formed.
With reference to FIG. 10 and FIG. 11, in the present embodiment, the pressing member 320 has a pressing portion 321, a holding portion 322, and a pivoting portion 323. The pivoting portion 323 is slidably pivoted to the sliding groove 313. Besides, the pivoting portion 323 is inserted into the elastic member 330, and the elastic member 330 is a torsion spring which constantly drives the pressing member 320 to move toward the recess 312. The holding portion 322 adjoins the pressing portion 321 and the pivoting portion 323 and is located outside the recess 312, and the pressing portion 321 is located above the pivoting portion 323 and faces the protrusion 311.
The pressing member 320 further has a leaning portion 324. The leaning portion 324 is extended from the pivoting portion 323 toward a direction away from the sliding groove 313 and is located below the holding portion 322. The holding portion 324 slidably presses against an inner wall 312a of the recess 312, such that the sliding groove 313 and the inner wall 312a provide the pressing member 320 with a route for sliding and rotating relative to the body 310. In detail, the inner wall 312a may be divided into a first guiding surface 312a1, a second guiding surface 312a2, and a step S1 between the first guiding surface 312a1 and the second guiding surface 312a2. The first guiding surface 312a1 and the second guiding surface 312a2 have an up-and-down layout, and the second guiding surface 312a2 adjoins the bottom surface 315a. A distance S2 from the first guiding surface 312a1 to the protrusion 311 is greater than a distance S3 from the second guiding surface 312a2 to the protrusion 311. When the portable electronic device 60 is not assembled to the body 310, the leaning portion 324 presses against the first guiding surface 312a1, and the pressing portion 321 is located in the recess 312 due to said distances S2 and S3.
When the portable electronic device 60 enables the protrusion 311 to be inserted into the slot 64 along the assembling direction D2, the sidewall 64a of the slot 64 presses against the holding portion 322 along the assembling direction D2, and the leaning portion 324 slides from the first guiding surface 312a1 to the second guiding surface 312a2. Further, due to said distances S2 and S3, the pivoting portion 323 is driven to slide along the sliding groove 313, and the pressing member 320 is rotated and moved out of the recess 312. Here, the leaning portion 324 presses against the second guiding surface 312a2, and the pressing portion 321 is moved out of the recess 312 and is in contact with the sidewall 64b along the pressing direction D3. Thereby, the portable electronic device 60 may be stably clamped by the protrusion 311 and the pressing portion 321, and thus the support stability of the docking station 300 may be significantly improved. In addition, a rubber layer (not shown) may be selectively located on the pressing portion 321, such that the pressing portion 321 of the pressing member 320 may be in close contact with the sidewall 64b by means of the rubber layer (not shown); at the same time, the rubber layer (not shown) may serve as a cushion for preventing abrasion among components.
To sum up, the docking station described herein includes the body, the pressing member, and the elastic member. The pressing member is movably arranged in the body by means of the elastic member, so as to be hidden in the body or moved out of the body. In an embodiment of the invention, when the protrusion of the body is lodged in the slot of the portable electronic device, the elastic member is further compressed, such that the pressing member moves toward the groove of the protrusion and is then hidden in the body. However, the pushing force of the elastic member still constantly drives the pressing member to press against the inside of the slot along the pressing direction. Thereby, after the portable electronic device and the docking station described in an embodiment are assembled, the gap between the protrusion and the slot may be removed. Moreover, according to another embodiment of the invention, if the portable electronic device enables the protrusion to be inserted into the slot along the assembling direction, the leaning portion slides from the first guiding surface of the inner wall of the recess to the second guiding surface. At this time, the leaning portion presses against the second guiding surface, and the pressing portion is moved out of the recess. As such, the portable electronic device may be securely clamped by the protrusion and the pressing portion. In conclusion, the docking station described herein may fix the portable electronic device to the support member of the docking station, so as to significantly enhance support stability of the docking station. Thereby, favorable quality of using the portable electronic device may be ensured.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the disclosed embodiments without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
