Description

    BACKGROUND
  • 1. Technical Field
  • The present disclosure relates to a chair and, particularly, to a power generating chair.
  • 2. Description of Related Art
  • Chairs are used at work and for relaxing. When a user sits down, leans back in the chair, or moves with the chair, the chair is pressed. Hence, utilizing the pressure is very important and ought to be considered in the design of chairs.
  • BRIEF DESCRIPTION OF THE DRAWINGS
  • FIG. 1 is an isometric view of a power generating chair, according to an exemplary embodiment.
  • FIG. 2 is an exploded view of the power generating chair of FIG. 1.
  • FIG. 3 is a side view of the power generating chair of FIG. 1.
  • DETAILED DESCRIPTION
  • Referring to FIG. 1, a power generating chair 100, according to an exemplary embodiment, includes a seat 10, a back 20, a connection member 30, a pair of armrests 40, a base 50, and a power-collecting module 60 (shown in FIG. 3).
  • Referring to FIGS. 1-2, the seat 10 includes an upper surface 10 a and a lower surface 10 b. The upper surface 10 a and the lower surface 10 b are positioned at opposite sides of the seat 10. The upper surface 10 a is configured for supporting users. The seat 10 includes a seat housing 12, a first cushion 14, and a second cushion 16. The first cushion 14 is received in the seat housing 12. The first cushion 14 is made of piezoelectric material and configured for converting mechanical energy to electrical power. The second cushion 16 is received in the seat housing 12 and positioned on the first cushion 14. The second cushion 16 is a solar panel and is configured for converting light energy to electrical power.
  • The back 20 includes a connection portion 20 a and a support portion 20 b. The connection portion 20 a and the support portion 20 b are positioned at opposite sides of the back 20. The back 20 includes a back housing 22, a first back plate 24, and a second back plate 26. The first back plate 24 is received in the back housing 22. The first back plate 24 is made of piezoelectric material and configured for converting mechanical energy to electrical power. The second back plate 26 engages with the back housing 22 and seals the back housing 22. The second back plate 26 is a solar panel and is configured for converting light energy to electrical power.
  • The connection member 30 defines a cutout 32. The connection member 30 protrudes from a side of the seat 10. The connection portion 20 a is fixed in the cutout 32 by means of a pivot 28. A preload force can be set between the connection portion 20 a and the pivot 28, such that the back 20 can rotate about the pivot 28 when a pressure applied to the back 20 is larger than the preload force.
  • The two armrests 40 extend from the two opposite sides of the seat 10. The back 20 is positioned between the two armrests 40.
  • Referring to FIGS. 2-3, the base 50 includes a support member 52 and a shaft 54. The support member 52 includes a pole 522, five radial-type legs 524, and five wheels 526. One end of the pole 522 is rotatably connected to one end of the shaft 54. The legs 524 extend from the other end of the pole 522. The wheels 526 are fixed on the respective legs 524 and rest on the ground. The wheels 526 are made of piezoelectric material and configured for converting mechanical energy to electrical power. The other end of the shaft 54 is fixed to the lower surface 10 b of the seat 10 to support the seat 10. The shaft 54 is made of piezoelectric material and configured for converting mechanical energy to electrical power.
  • The power-collecting module 60 is a storage battery. The power-collecting module 60 is fixed on the lower surface 10 b and is mechanically connected to the shaft 54. The power-collecting module 60 is electrically connected to the first cushion 14, the second cushion 16, the first back plate 24, the second back plate 26, the wheels 526, and the shaft 54 by wires (not shown), thereby any electrical power generated by the first cushion 14, the second cushion 16, the first back plate 24, the second back plate 26, the wheels 526, and the shaft 54, flows into and is stored in the power-collecting module 60.
  • In this embodiment, the piezoelectric material includes organic piezoelectric material, inorganic piezoelectric material, or compound piezoelectric material. The organic piezoelectric material may be polyvinylidene fluoride. The inorganic piezoelectric material may be piezotransistors or piezoceramics. A piezotransistor may include quartz crystal, lithium gallium oxide, lithium germinate, lithium niobate and lithium tantalite. The piezoceramics may include barium titanate, barium zirconate titanate, modified barium zirconate titanate, and modified lead titanate. The compound piezoelectric material may include a polymer base, in which organic piezoelectric material and inorganic piezoelectric material are embedded.
  • If a user sits on the power generating chair 100, a pressure will be applied to the first cushion 14 and the wheels 526. Then, the first cushion 14 and the wheels 526 transform the mechanical energy to electrical power. If the user leans back in the power generating chair 100, a pressure will also be applied to the first back plate 24. Then, the first back plate 24 transforms the mechanical energy to electrical power. If the user rotates the power generating chair 100, a pressure and torque will be applied to the shaft 54. Then, the shaft 54 transforms the mechanical energy to electrical power. If the power generating chair 100 is moved, a rolling pressure is applied peripherally to the wheels 526. Then, the first cushion 14 and the wheels 526 transform the mechanical energy to electrical power. In addition, when the second cushion 16 and the second back plate 26 face towards a bright light such as the sun, the second cushion 16 and the second back plate 26 can transform light energy to electrical power. The power-collecting module 60 stores all the electrical power generated. In another embodiment, the electrical power may be provided directly to other electronic devices. Thus, the simple act of sitting in the power generating chair 100 can provide additional electrical power for charging the battery and/or powering electronic devices, achieving good energy conservation.
  • In another embodiment, the support member 52 includes a pole. One end of the pole is rotatably connected to one end of the shaft 54, and the other end of the pole is supported by the ground.
  • It is to be understood, however, that even though numerous characteristics and advantages of the present embodiments have been set fourth in the foregoing description, together with details of the structures and functions of the embodiments, the disclosure is illustrative only, and changes may be made in details, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
