DESCRIPTION OF EMBODIMENTS

      Referring to FIG. 1A and FIG. 2, in the present embodiment, an accessory 100 is adapted to be connected to a portable device 50 (e.g., a smart phone) having a display 52 (as shown in FIG. 3). Users can experience a three-dimensional visual effect by viewing virtual reality images displayed by the display 52 of the portable device 100. The accessory 100 includes a lens frame 110 and a pair of lenses 120. The pair of lenses 120 are, for example, convex lenses and disposed on the lens frame 110. Specifically, the lens frame 110 includes a spacer plate 111, a lens plate 112 and a pair of foldable plates 113. The spacer plate 111 is coupled to the portable device 50. The lens plate 112 is flexibly connected to the spacer plate 111. One of the pair of foldable plates 113 is flexibly connected between one end of the space plate 111 and one corresponding end of the lens plate 112, and another of the pair of foldable plates 113 is flexibly connected between another end of the space plate 111 and another corresponding end of the lens plate 112. The pair of lenses 120 are disposed on the lens plate 112, and positioned in front of the display 52 of the portable device 50 in a using state. In the present embodiment, the lens frame 110 may include a soft skin 110 a so aforementioned members included by the lens frame 110 can be flexibly connected to one another through the soft skin 110 a. Further, the lens plate 112 may have a notch 112 a, which is between the pair of lenses 120 and adapted to accommodate a user's nose bridge.
      Referring to FIG. 1A, in the present embodiment, the pair of foldable plates 113 are unfolded in the using state so the lens plate 112 is opened in a preset angle relative to the spacer plate 111, so the pair of lenses 120 disposed on the lens plate 112 can be positioned in front of the display 52 of the portable device 50 in the using state. When not in use, the user may flip the lens frame 110 to the rear side of the portable device 50 (as shown in FIG. 1B). Next, as shown in FIG. 1B, the pair of foldable plates 113 may be manually folded to move the lens plate 112 and the spacer plate 111 close to each other. Lastly, as shown in FIG. 1C, the pair of foldable plates 113 are folded in a folding state so the spacer plate 111 and the lens plate 112 overlap each other. In the present embodiment, the pair of foldable plates 113 are folded between the spacer plate 111 and the lens plate 112 in the folding state.
      Referring to FIG. 1B and FIG. 2, in the present embodiment, each of the foldable plates 113 includes a first triangular portion 113 a and a second triangular portion 113 b, the first triangular portion 113 a has a first folding edge 113 a- 1 and a first connecting edge 113 a- 2, the second triangular portion 113 b has a second folding edge 113 b- 1 and a second connecting edge 113 b- 2, the first folding edge 113 a- 1 of each of the first triangular portions 113 a and the second folding edge 113 b- 1 of the corresponding second triangular portion 113 b are connected to each other, the first connecting edge 113 a- 2 of each of the first triangular portions 113 a is flexibly connected to the spacer plate 111, and the second connecting edge 113 b- 2 of each of the second triangular portions 113 b is flexibly connected to the lens plate 112 separately. In the present embodiment, the first folding edge 113 a- 1 of each of the first triangular portions 113 a and the second folding edge 113 b- 1 of the corresponding second triangular portion 113 b are connected to each other due to magnetic attraction.
      Referring to FIG. 1B and FIG. 2, in the present embodiment, the accessory 100 may further include at least two pairs of folded magnetic members 131 (e.g., a plurality of permanent magnets). Each pair of folded magnetic members 131 is separately disposed between the first folding edge 113 a- 1 of the corresponding first triangular portion 113 a and the second folding edge 113 b- 1 of the corresponding second triangular portion 113 b so a magnetic force from the pairs of folded magnetic members 131 is able to maintain the foldable plates 113 unfolded in the using state. In the present embodiment, the two pairs of folded magnetic members 131 are adopted to provide the magnetic force between each first folding edge 113 a- 1 and the corresponding second folding edge 113 b- 1.
      Referring to FIG. 1B, in the present embodiment, each of the foldable plates 113 has a concave surface 113 c caved to the corresponding first triangular portion 113 a, and the concave surface 113 c approximately matches a shape of the corresponding lens 120. Therefore, in the folding state, the first triangular portion 113 a of the foldable plate 113 may be prevented from structural mutual interference with the corresponding lens 120 through the concave 113 c, and thus the wearing of the lenses 120 may also be prevented.
      Referring to FIG. 1B and FIG. 2, in the present embodiment, the accessory 100 may further include a plurality of overlapping magnetic members 132 (e.g., a plurality of permanent magnets). They are embedded in part or all of a group composed of the spacer plate 111, the lens plate 112 and the foldable plates 113 so a magnetic force from at least part of the overlapping magnetic members 132 is able to maintain the spacer plate 111 and the lens plate 112 overlapping each other in the folding state and the magnetic force of the at least part of the overlapping magnetic members 132 is able to maintain the foldable plates 113 unfolded in the using state. Referring to FIG. 2, double arrows indicate the situation where these overlapping magnetic members 132 are attached to each other in pairs in the folding state.
      Referring to FIG. 1A and FIG. 2, in the present embodiment, the lens frame 110 further includes a cross over plate 115, which is flexibly connected to the spacer plate 111 and coupled to the portable device 50 to cross over a side edge of the portable device 50.
      Referring to FIG. 2, FIG. 3A and FIG. 3B, in the present embodiment, the lens frame 110 further includes a mounting plate 114. The mounting plate 114 is flexibly connected to the spacer plate 111 and adapted to be assembled to a protective case 60. Further, in the present embodiment, the mounting plate 114 has a plurality of accessory fitting portions 114 a (e.g., a plurality of fitting pillars) adapted to be coupled to a plurality of device fitting portions 60 a (e.g., a plurality of fitting holes) of the protective case 60. In the present embodiment, the protective case 60 refers to a protective shell which allows the portable device 50 to be disposed in the protective case 60. In another embodiment not illustrated, the mounting plate 114 is flexibly connected to the spacer plate 111, and adapted to be directly assembled to an original housing of the portable device 50. In another embodiment not illustrated, the accessory 100 further includes a protective case (similar to the protective case 60 of FIG. 1A), which is flexibly connected to the spacer plate 111, and adapted to be mounted on the portable device 50. In this case, the mounting plate 114 of FIG. 1A may be omitted.
      Referring to FIG. 1A, FIG. 1B and FIG. 1C, the portable device 50, the lens frame 110 and the pair of lenses 120 can constitute a lens system 10, which may also include other members. The lens system 10 can generate virtual reality images through the display 52 of the portable device 50 and allows user eyes to view the virtual reality images through the pair of lenses 120. Moreover, in the present embodiment, the lens system 10 may further include the protective case 60. The portable device 50 is disposed in the protective case 60. The spacer plate 111 is flexibly connected to one side of the protective case 60. The spacer plate 111 is coupled to the portable device 50 via the protective case 60.
      In summary, in the present application, the pair of lenses of the accessory or the lens system can be positioned in front of the display of the portable device so the user eyes are able to view the virtual reality images displayed by the display through the pair of lenses. In addition, the lens frame of the accessory or the lens system may also be folded on the portable device, which is advantageous for users to carry around.
