[0054] Please see Figure 1 , Figure 2 and Figure 3 The base 1000 of this application includes a bottom shell 1, a central sliding member 2, a cover unit 3, a left movable shell 4, and a right movable shell 5. The central sliding member 2 is disposed on the bottom shell 1, and the cover unit 3 is disposed on the bottom shell 1, with the central sliding member 2 located between the bottom shell 1 and the cover unit 3. The left movable shell 4 and the right movable shell 5 are respectively movably disposed on the bottom shell 1 and located on opposite sides of the central sliding member 2. The structure of each component and the connection relationship between them will be described in detail below. In some of the drawings, a first direction X1 and a second direction X2 that are perpendicular to each other are shown.

[0055] The bottom shell 1 includes a shell 11, eight central positioning posts 12, four left positioning posts 13, four right positioning posts 14, a first electrical connection portion 15, and a cylinder 16. The shell 11 is generally octagonal in shape and has a front edge 111 and a rear edge 114, and a left edge 112 and a right edge 113 adjacent to opposite sides of the front edge 111 and the rear edge 114. The central positioning posts 12 are spaced apart from each other on the shell 11 and arranged in pairs along a first direction X1, and are located between the front edge 111 and the rear edge 114. The left positioning posts 13 are spaced apart from each other on the shell 11 and adjacent to the left edge 112. The right positioning posts 14 are spaced apart from each other on the shell 11 and adjacent to the right edge 113. The first electrical connection portion 15 is located on the shell 11 and adjacent to the rear edge 114, and has a conductive sheet on its top surface. The cylinder 16 is disposed on the housing 11 and adjacent to the rear edge 114, and is spaced apart from the first electrical connection portion 15.

[0056] The central sliding member 2 includes a body 21, four left sliding rails 22, four right sliding rails 23, eight central sliding grooves 24, a second electrical connection 25, a through hole 26, and four fixing parts 27. The body 21 is generally trapezoidal plate-shaped and is disposed on the housing 11. (See reference...) Figure 5 and Figure 7 The left slide sections 22 are spaced apart on the left side of the body 21 and each has a first left inclined surface 221 and a second left inclined surface 222. The extending directions of the first left inclined surface 221 and the second left inclined surface 222 are parallel to each other and oblique to the first direction X1. The right slide sections 23 are spaced apart on the right side of the body 21 and each has a first right inclined surface 231 and a second right inclined surface 232. The extending directions of the first right inclined surface 231 and the second right inclined surface 232 are parallel to each other and oblique to the first direction X1, and are different from the extending directions of the first left inclined surface 221 and the second left inclined surface 222. The central slide grooves 24 are spaced apart and extend through the body 21, respectively, along the first direction X1, and are arranged in pairs along the first direction X1. One cross-section of the central sliding groove 24 is larger than one cross-section of the central positioning post 12, and the central positioning post 12 is correspondingly slidably disposed in the central sliding groove 24, allowing the central sliding member 2 to move relative to the bottom shell member 1 along the first direction X1. A second electrical connection portion 25 is disposed on the body 21 and adjacent to the rear edge portion 114, and has a conductive sheet on its top surface. A through hole 26 is formed through the body 21 and adjacent to the second electrical connection portion 25, and allows the first electrical connection portion 15 to pass through, so that the first electrical connection portion 15 corresponds to the second electrical connection portion 25. One cross-section of the through hole 26 is larger than one cross-section of the first electrical connection portion 15. Fixed portions 27 are spaced apart on the body 21 and adjacent to the front edge portion 111.

[0057] Please refer to the following: Figure 3 and Figure 4 The cover unit 3 includes a front cover 31, an upper cover 32, a left decorative element 33, and a right decorative element 34. The front cover 31 is generally trapezoidal in shape and has four fixed posts 311, which are spaced apart and fixed to the fixed parts 27, allowing the front cover 31 to move in tandem with the central sliding member 2. The upper cover 32 is generally trapezoidal in shape and has a circular hole 321 through which a cylinder 16 passes, allowing the upper cover 32 to be fixed to the bottom shell 1 and spaced apart from the front cover 31. The central sliding member 2 is located between the upper cover 32 and the bottom shell 1. The common geometric shape of the front cover 31 and the upper cover 32 matches the geometric shape of the central sliding member 2. The left decorative element 33 and the right decorative element 34 are generally bent elongated blocks and are fixed to the left and right sides of the upper cover 32, respectively.

[0058] In one embodiment, the colors of the left decorative element 33 and the right decorative element 34 may be different from the colors of the front cover 31, the upper cover 32, the left movable shell 4, and the right movable shell 5. In another embodiment, the left decorative element 33 and the right decorative element 34 may be a transparent shell with at least one light-emitting element (e.g., an LED). The light-emitting element receives power and emits light when it is electrically connected to the second electrical connection 25 via the first electrical connection 15, and the color, flashing frequency, etc., of the light emitted by the light-emitting element can be set as needed.

[0059] The left movable shell 4 is movably disposed on the bottom shell 1 and located to the left of the central sliding member 2, and includes a left shell 41, a left block 42, four left sliders 43, four left sliding grooves 44, and two left protrusions 45. The left shell 41 is disposed to the left of the front cover 31 and the upper cover 32, and the side adjacent to the front cover 31 and the upper cover 32 matches the geometric shape of the left side of the front cover 31 and the upper cover 32, and is partially located above the left decorative member 33. The left shell 41 has two left recesses 411 spaced apart from each other. The left block 42 is disposed between the left shell 41 and the shell 11, located to the left of the body 21 of the central sliding member 2 and adjacent to the left edge 112. The left sliders 43 are spaced apart on the left block 42 and correspondingly slide on the left slide rail 22, and each has a first left pushing surface 431 and a second left pushing surface 432 that are opposite to each other. The extension directions of the first left pushing surface 431 and the second left pushing surface 432 are parallel to each other and oblique to the second direction X2. The left slide grooves 44 are spaced apart and are formed through the left block 42, and extend along the second direction X2. One cross section of the left slide groove 44 is larger than one cross section of the left positioning post 13, and the left positioning post 13 is correspondingly slidably mounted on the left slide groove 44, so that the left block 42 can move relative to the bottom shell 1 along the second direction X2. The left protrusions 45 are spaced apart and protrude from the left block 42, and respectively engage with the left recesses 411 of the left shell 41, so that the left shell 41 and the left block 42 move together.

[0060] The right movable shell 5 is movably disposed on the bottom shell 1 and located to the right of the central sliding member 2, and includes a right shell 51, a right block 52, four right sliders 53, four right sliding grooves 54, and two right protrusions 55. The right shell 51 is disposed on the right side of the front cover 31 and the upper cover 32, and the side adjacent to the front cover 31 and the upper cover 32 matches the geometric shape of the right side of the front cover 31 and the upper cover 32, and is partially located above the right decorative member 34. The right shell 51 has two right recesses 511 spaced apart from each other. The right block 52 is disposed between the right shell 51 and the shell 11, located to the right of the body 21 of the central sliding member 2 and adjacent to the right edge 113. The right sliders 53 are spaced apart from each other on the right block 52 and are respectively slidably disposed on the right slide rail portion 23. Each slider has an opposite first right pushing surface 531 and a second right pushing surface 532. The extension directions of the first right pushing surface 531 and the second right pushing surface 532 are parallel to each other and obliquely intersecting the second direction X2, and are different from the extension directions of the first left pushing surface 431 and the second left pushing surface 432. The right sliding grooves 54 are spaced apart and are formed through the right block 52, extending along the second direction X2. One cross-section of the right sliding groove 54 is larger than one cross-section of the right positioning post 14, and the right positioning post 14 is correspondingly slidably disposed on the right sliding groove 54, allowing the right block 52 to move relative to the bottom shell 1 along the second direction X2. The right protrusions 55 are spaced apart from each other on the right block 52 and are respectively snapped into the right recesses 511 of the right shell 51, so that the right shell 51 and the right block 52 move together.

[0061] The following describes the operation of the base 1000 of this application. The base 1000 can be in a closed state ( Figure 5 and Figure 6 ) and an open state ( Figure 7 and Figure 8 ( ) Transformation. In the off state, such as Figure 5 (Drawing of cover unit 3, left shell 41, and right shell 51 omitted) As shown, the left slider 43 slides on the left slide rail 22, so that the first left pushing surface 431 and the second left pushing surface 432 correspond to the first left inclined surface 221 and the second left inclined surface 222, respectively. The right slider 53 slides on the right slide rail 23, so that the first right pushing surface 531 and the second right pushing surface 532 correspond to the first right inclined surface 231 and the second right inclined surface 232, respectively. At this time, the central positioning post 12 abuts against the lower end of the central slide groove 24, the left positioning post 13 abuts against the left end of the left slide groove 44, the right positioning post 14 abuts against the right end of the right slide groove 54, and the second electrical connection part 25 abuts against the lower end of the through hole 26 and is far away from and not electrically connected to the first electrical connection part 15 (for example, the conductive pieces are not in contact with each other and the circuit is broken). Figure 6As shown, the left movable shell 4 abuts against the left side of the central sliding member 2 and covers the left decorative member 33, and the right movable shell 5 abuts against the right side of the central sliding member 2 and covers the right decorative member 34.

[0062] When the user applies an external force to the front cover 31, causing the front cover 31 to move along the first direction X1 toward the front edge 111 in conjunction with the central sliding member 2, the base 1000 changes from the closed state to the open state. At this time, the central positioning post 12 gradually moves from the lower end to the upper end of the central slide groove 24, and the first left inclined surface 221 pushes the first left pushing surface 431, so that the first left inclined surface 221 and the second left inclined surface 222 gradually misalign with the first left pushing surface 431 and the second left pushing surface 432 respectively. At the same time, the left positioning post 13 gradually moves from the left end to the right end of the left slide groove 44, driving the left movable shell 4 to move along the second direction X2 toward the left edge 112. Similarly, the first right inclined surface 231 pushes against the first right pushing surface 531, causing the first right inclined surface 231 and the second right inclined surface 232 to gradually misalign with the first right pushing surface 531 and the second right pushing surface 532, respectively. Simultaneously, the right positioning post 14 gradually moves from the right end of the right slide groove 54 to the left end, driving the right movable housing 5 to move along the second direction X2 towards the right edge 113. The second electrical connection part 25 gradually moves from the lower end of the through hole 26 to the upper end.

[0063] When the base 1000 is in the open state, such as Figure 7 (Drawing of cover unit 3, left shell 41, and right shell 51 omitted) As shown, the central positioning post 12 abuts against the upper end of the central slide groove 24, the left positioning post 13 abuts against the right end of the left slide groove 44, and the right positioning post 14 abuts against the left end of the right slide groove 54. The left slider 43 slides away from the left slide section 22, so that the first left inclined surface 221 and the second left inclined surface 222 are completely misaligned with the first left pushing surface 431 and the second left pushing surface 432, respectively. The right slider 53 slides away from the right slide section 23, so that the first right inclined surface 231 and the second right inclined surface 232 are completely misaligned with the first right pushing surface 531 and the second right pushing surface 532, respectively. The second electrical connection part 25 is adjacent to the upper end of the through hole 26 and the first electrical connection part 15 and is electrically connected to the first electrical connection part 15 (for example, conductive sheets contact each other to form a passage, which can provide power to the light-emitting element). Figure 8 As shown, at this time, the left movable shell 4 is away from the central sliding member 2, the front cover 31 and the upper cover 32, and the exposed part is the left decorative member 33; the right movable shell 5 is away from the central sliding member 2, the front cover 31 and the upper cover 32, and the exposed part is the right decorative member 34.

[0064] To change the base 1000 from the open to the closed state, the user simply applies an external force to the front cover 31, causing the front cover 31 to move along the first direction X1 away from the front edge 111 (i.e., towards the rear edge 114). The second left inclined surface 222 contacts the second left pushing surface 432, causing the left slider 43 to slide into the left slide rail 22, and driving the left movable shell 4 away from the left edge 112 along the second direction X2, until the first left inclined surface 221 and the second left inclined surface 222 are completely closed. The first left sliding surface 431 and the second left sliding surface 432 are fully aligned, at which point the left movable shell 4 covers the left decorative piece 33; the second right inclined surface 232 contacts the second right sliding surface 532, causing the right slider 53 to slide into the right slide section 23, and driving the right movable shell 5 away from the right edge section 113 along the second direction X2, until the first right inclined surface 231 and the second right inclined surface 232 are fully aligned with the first right sliding surface 531 and the second right sliding surface 532 respectively, at which point the right movable shell 5 covers the right decorative piece 34.

[0065] In summary, the base of this application allows for simultaneous control of the movement of both the left and right movable shells by operating the central sliding member. The left and right decorative parts can be exposed or covered as needed, resulting in a dynamic overall design that enhances lighting effects, adds to the product's features, and provides an excellent user experience.

The base as described in claim 8, characterized in that, When the base changes from the closed state to the open state, the right slider slides away from the right slide rail and drives the right movable shell to move towards the right edge along the second direction. When the base changes from the open state to the closed state, the right slider slides into the right slide rail and drives the right movable shell away from the right edge along the second direction. The right slide rail has a first right inclined surface and a second right inclined surface, the extension directions of which are oblique to the first direction. The right slider has a first right pushing surface and a second right pushing surface, which are opposite to each other. The extension direction of the surface is oblique to the second direction, and the extension directions of the first left inclined surface and the second left inclined surface are different from the extension directions of the first right inclined surface and the second right inclined surface. The extension directions of the first left pushing surface and the second left pushing surface are different from the extension directions of the first right pushing surface and the second right pushing surface. In the closed state, the first right pushing surface and the second right pushing surface correspond to the first right inclined surface and the second right inclined surface, respectively. In the open state, the first right pushing surface and the second right pushing surface are respectively misaligned with the first right inclined surface and the second right inclined surface.
