DETAILED DESCRIPTION
Reference will now be made in detail to the present embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
Please refer to FIG. 1, an exploded view of an embodiment of the present invention. A conjunctive structure 1 comprises a baseboard 11 with a hole 110 at the center, a peripheral element 10, a supporting board 12 and a connecting apparatus. The connecting apparatus comprises four first magnetic connecting elements 101a, 101b, 101c, and 101d those are placed on the four corners of the peripheral element 10; and four second magnetic connecting elements 111a, 111b, 111c, and 111d those are placed around the hole 110 of the baseboard 11 corresponding to the four first magnetic connecting elements 101a, 101b, 101c, and 101d, respectively. The peripheral element 10 comprising a bulge 102, wherein the shape and the size of the bulge 102 is compatible to the hole 110 of the baseboard 11. One side of the bulge 102 further comprises a chamfer 100. The height of the chamfer 100 is as adaptive with thickness of the baseboard 11. The supporting board 12 is connected in parallel to the baseboard 11 by four elastic elements 120a, 120b, 120c, and 120d such as torsion springs which provide a supporting force and an elastic force when the peripheral element 10 and baseboard 11 are connected and separated with each other, respectively. In an embodiment, the baseboard 11 is a shell of an electronic device (e.g. a laptop or a cell phone). The peripheral element 10 is a peripheral device of the electronic device such as a display, a multimedia operation interface or a network phone.
Please refer to FIG. 2 at the same time, wherein FIG. 2 is a bottom view of the peripheral element 10 of the present invention. The four first magnetic connecting elements 101a, 101b, 101c and 101d, for example magnets, are placed on the four corners of the peripheral element 10 as shown in FIG. 2 with N-pole sides of the magnets. The four second magnetic connecting elements 111a, 111b, 111c and 111d are placed around (on the four corners for example) the hole 110 of the baseboard 11 corresponding to the position of the four first magnetic connecting elements 101a, 101b, 101c and 101d; each of the second magnetic connecting elements 111a, 111b, 111c and 111d comprises one magnet or two adjacent magnetic elements with opposite polarity arrangement as shown in FIG. 1, wherein the left side is S-pole and the right side is N-pole. People skilled in the art can easily modify the number and the placement-of the first and second magnetic connecting elements described above, and the first and second magnetic connecting elements are not necessarily magnets and can be replaced by other magnetic material.
For connecting the baseboard 11 with the peripheral element 10, the bulge 102 of the peripheral element 10 has to be aligned to the hole 110 of the baseboard 11 first and then push the bulge 102 into the hole 110 to make the N-pole sides of the four first magnetic connecting elements 101a, 101b, 101c and 101d face to the N-pole side (right side) of the second magnetic connecting elements 111a, 111b, 111c and 111d, respectively. At the same time, the repulsion forces the peripheral element 10 to move to the S-pole side (left side) attractive to the four first magnetic connecting elements 101a, 101b, 101c and 101d. The baseboard 11 and peripheral element 10 are therefore connected to each other. FIG. 3 is a side view of the conjunctive structure 1 after being connected. After the four first magnetic connecting elements 101a, 101b, 101c and 101d are respectively attracted to the S-pole sides of the second magnetic connecting elements 111a, 111b, 111c and 111d, the chamfer 100 on the bulge 20 102 of the peripheral element 10 the baseboard 11 would fit with the baseboard 11, thus the connection of the baseboard 11 and the peripheral element 10 could be enhanced. Besides, the elastic elements 120a, 120b, 120c and 120d are stretched due to the pressure or push of the bulge 102 of the peripheral element 10, thus further support the peripheral element 10.
For separating the baseboard 11 and the peripheral element 10, the peripheral element 10 has to be pushed transversely to force the chamfer 100 of the bulge 102 out of the baseboard 11. The four first magnetic connecting elements 101a, 101b, 101c and 101d thus displace from facing the S-pole sides of the second magnetic connecting elements 111a, 111b, 111c and 111d to face the N-pole sides of the second magnetic connecting elements 111a, 111b, 111c and 111d. Therefore, a repulsive force is generated and the elastic elements 120a, 120b, 120c and 120d provide elastic forces at the same time to push out the peripheral element 10 from the hole 110 of the baseboard 10.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims.
