Then, the pressing element 82 of the portable electronic apparatus 80 can contact with the first operating portion 41 of the operating element 40 protruded from the main body 10, such that the first operating portion 41 is pressed to swing and move relative to the moving element 20 with the aforementioned pivot P (as the direction of the arrow shown in the figure). The second operating portion 42 can be driven to escape from the stop portion 11, so that the moving element 20 can be moved towards the locking position by the first elastic element 30.
Please refer to both FIG. 7(a) and FIG. 7(b). FIG. 7(a) is an overall schematic view of the expanding platform 1 of the present invention after the portable electronic apparatus 80 has been inserted therein; FIG. 7(b) is a partial schematic view of the expanding platform 1 of the present invention after the portable electronic apparatus 80 has been inserted therein.
As shown in FIG. 7(a) and FIG. 7(b), when the portable electronic apparatus 80 has been inserted, the corresponding connection interface 84 of portable electronic apparatus 80 has been electrically connected to the connection interface 12 of main body 10, and the moving element 20 has been moved to the locking position. By the fixed effect generated by each fixed element 21 on the moving element 20 with the corresponding fixed structure 83 in the receiving portion 81 of the portable electronic apparatus 80. Therefore, the portable electronic apparatus 80 is firmly inserted into the expanding platform 1 of the present invention.
Please also refer to FIG. 7(a) to FIG. 7(c). FIG. 7(c) is a partial schematic view of the expanding platform 1 of the present invention when the portable electronic apparatus 80 is in an unlocking process.
As shown in FIG. 7(a) and FIG. 7(b), when the user wants to make the portable electronic apparatus 80 detach from the expanding platform 1 of the present invention, in this embodiment, the user presses the button element 70 first to push the pushed portion 22 to laterally move the entire moving element 20, such that each fixed element 21 escapes from each aforementioned corresponding fixed structure 83. With the moving element 20 continuously moving towards the unlocking position, the first elastic element 30 can be stretched out. At this time, the second operating portion 42 of operating element 40 will contract with the stop portion 11. By the interaction of the second inclined plane 42a and second corresponding inclined plane 11a, the operating element 40 moves relative to the moving element 20 and drives the second operating portion 42 to cross the stop portion 11.
As shown in FIG. 7(c), the first operating portion 41 of the operating element 40 will contract with the pressing element 82 of the portable electronic apparatus 80. By the interaction of the first inclined plane 41a of the first operating portion 41 and the first corresponding inclined plane 82a of the pressing element 82, the pressing element 82 is protruded upward to make the corresponding connection interface 84 and the connection interface 12 gradually lose and easy for a user to pull the portable electronic apparatus 80 away; on the other hand, the first operating portion 41 crosses the pressing element 82 with the movement of the operating element 40. Finally, the moving element 20 reaches the unlocking position as shown in FIG. 8(b) described thereinafter.
FIG. 8(a) is an overall schematic view of the expanding platform 1 of the present invention after the portable electronic apparatus 80 has been unlocked; FIG. 8(b) is a partial schematic view of the expanding platform 1 of the present invention after the portable electronic apparatus 80 has been unlocked.
As shown in FIG. 8(a) and FIG. 8(b), when the portable electronic apparatus 80 is not completely pulled away, the moving element 20 is temporarily fixed at the unlocking position by the pressing element 82 blocking the first operating portion 41. At this time, the portable electronic apparatus 80 is unlocked from the expanding platform 1 of the present invention by the aforementioned operation, the user is allowed to pull the portable electronic apparatus 80 away with a single hand. When the portable electronic apparatus 80 is completely pulled away, the moving element 20 without blocking can be moved back again by the first elastic element 30 until the second operating portion 42 is stopped by the stop portion 11. Therefore, the moving element 20 can be moved back to the initial position as shown in FIG. 5(a).
Please refer to FIG. 9, which is a structure view of the moving element 20a and operating element 40a of the expanding platform 1 in a second embodiment of the present invention.
The present embodiment is a variation of the aforementioned first embodiment. As shown in FIG. 9, in this embodiment, by the structural design, the operating element 40a further includes a sleeve-connecting portion 43. The operating element 40a can be slidably connected to the corresponding sliding portion of the moving element 20a by the sleeve-connecting portion 43. In addition, a second elastic element 60 is disposed between the operating element 40a and moving element 20a (i.e. disposed in a sliding direction substantially parallel to the operating element 40a relative to the moving element 20a) for connecting both to provide the restoring effect after the operating element 40a is forced to move relative to the moving element 20a. Therefore, when the first operating portion 41 or the second operating portion 42 of the operating element 40a is forced to move, the operating element 40a can be slidably moved relative to the moving element 20a to escape from the corresponding structure and can move back to its original location by the second elastic element 60.
In addition, the present invention further comprises a portable electronic apparatus 80 that is applied to the aforementioned expanding platform 1 so as to be correspondingly inserted into the expanding platform 1. As shown in FIG. 1 and FIG. 6(a), the portable electronic apparatus 80 comprises a casing 85, a corresponding connection interface 84, at least one receiving portion 81, and at least one pressing element 82. The corresponding connection interface 84, at least one receiving portion 81 and at least one pressing element 82 are all disposed within the casing 85, wherein the disposed number and position of the at least one receiving portion 81 and at least one pressing element 82 can be determined according to the number and position of the corresponding positioning element 13, fixed element 21, and operating element 40 of the expanding platform 1, but are not limited to the present embodiment.
The corresponding connection interface 84 of the portable electronic apparatus 80 is used for electrically connecting the connection interface 12 of the expanding platform 1. Each receiving portion 81 is formed as a receiving space for inserting each positioning element 13 and each fixed element 21 of the expanding platform 1. Each receiving portion 81 comprises a corresponding fixed structure 83, and each corresponding fixed structure 83 is used for correspondingly fixing each fixed element 21. At least one pressing element 82 is disposed within at least one receiving portion 81. The pressing element 82 is used for pressing against (when the moving element 20 is in the initial position) or blocking (when the moving element 20 is in the unlocking position) the first operating portion 41 of the operating element 40. In this embodiment, the pressing element 82 includes a first corresponding inclined plane 82a configured to correspond to the first inclined plane 41a of the first operating portion 41. When the moving element 20 is moved from the locking position to the unlocking position, by the interaction of the first corresponding inclined plane 82a of the pressing element 82 and the first inclined plane 41a of the first operating portion 41, the portable electronic apparatus 80 can be detached from the expanding platform 1.
Through the design of the present invention, the expanding platform for the portable electronic apparatus can provide the function of easily assembling and disassembling the portable electronic apparatus. With a single-hand operation, the portable electronic apparatus can be inserted and fixed at the expanding platform in the present invention. To detach from the portable electronic apparatus, the button element can be controlled by single hand control, such that the portable electronic apparatus can be apart from the expanding platform in the present invention. Therefore, the portable electronic apparatus can be pulled away by a user with a single hand. Since attaching and detaching of the portable electronic apparatus can be completed by a user with a single hand, the present invention can effectively improve the inconvenience of assembling and disassembling the portable electronic apparatus, and provides a stable fixed effect for inserting the portable electronic apparatus into the expanding platform.
As described above, the objectives, means, and effectiveness in the present invention are different to the characteristics in the prior art. It should be noted that the embodiments described above are for illustrating the principles and effects of the present invention, not for limiting the scope of the present invention.
