Figures 1 and 2 show the self-powered swivel seat in a seating mode from diagonally forward and diagonally rearward, respectively. The self-powered swivel chair comprises legs 10 and a chair body 20, the chair body 20 comprising a back 21 and a seat 22. The back 21 and seat 22 may be unitary or may be assembled together as separate components. The leg support 10 is placed on both sides in the length direction (in the shoulder width direction of the occupant) of the seat main body 20. A turnover mechanism 40 for turning over the seat main body 20 about a horizontal axis is provided between the seat main body 20 and the leg 10. In addition, the self-powered swivel seat is further provided with a solar panel 30, and the solar panel 30 is electrically connected to the reclining mechanism 40 so as to supply power to the reclining mechanism 40 to drive the seat main body 20 to rotate relative to the leg 10 through the reclining mechanism 40.

The leg 10 may be in the form of any conventional seat leg, such as a post leg or the like. The legs 10 may be placed on the ground. Alternatively, the leg 10 may be fixed to the ground. In the present embodiment, the leg 10 is configured as the same two triangular plates, alternatively, isosceles triangular plates, respectively arranged at both sides of the seat main body 20 in the length direction. One side of the triangular plate serves as a leg bottom surface contacting the ground, and a horizontal axis of the seat main body 20 rotating about the leg 10 passes near an apex of the triangular plate opposite to the side. By providing the leg 10 in a triangular plate shape, the stability of the seat during the rotation of the seat main body 20, and the stability of the seating of the seat can be improved. Alternatively, a chamber may be provided inside one or both of the two triangular plate-shaped legs 10 to accommodate at least a part of the turnover mechanism 40, such as a motor, a control circuit, and the like, which will be described later.

The turnover mechanism 40 comprises a pivot shaft, a transmission mechanism and a motor, the motor is electrically connected with the solar power generation panel 30, and the transmission mechanism is in transmission connection with the pivot shaft and an output shaft of the motor respectively.

The pivot shaft is fixed to the seat main body 20. Alternatively, the pivot shafts protrude outward in the longitudinal direction (horizontal direction) from both sides of the seat main body 20 (e.g., from the vicinity of the intersection of the back 21 and the seat 22), respectively. Accordingly, a pivot hole engaged with a pivot shaft protruding from both sides of the seat body 20 is further formed near the aforementioned apex of the leg 10 of the triangular plate shape, and the pivot shaft is connected to the leg 10 through the pivot hole in the leg 10. Optionally, the inner surface of the pivot bore is fitted with a bushing or bearing. Fig. 1 to 3 only schematically show views in which the pivot shaft is engaged with the pivot hole as viewed from the outside when the triangular plate has the pivot hole as a through hole.

The transmission mechanism may include a driven gear fitted around at least one of the two pivot shafts, and a drive gear connected to an output shaft of the motor and engaged with the driven gear.

The solar power generation panel 30 supplies power to the motor, the output shaft of the driving motor rotates to drive the driving gear to rotate, the driving gear drives the driven gear which is meshed with the driving gear and sleeved on the pivot shaft to rotate, and the driven gear drives the pivot shaft extending out of the seat main body 20 to rotate so as to drive the seat main body 20 to rotate. Thus, the seat main body 20 can be rotated about the leg 10 by the driving of the motor.

The motor may be arranged in a cavity in the triangular plate-shaped leg 10 and the output shaft of the motor may extend upwards. The motor may be directly electrically connected to the solar power generation panel 30 provided on the swivel seat. Alternatively, the motor may be electrically connected to the solar power generation panel 30 through a storage battery (not shown) and/or a control circuit.

Canting mechanism 40 may also include control circuitry and control buttons 50. The control buttons 50 may be used to send operating instructions to the control circuit, which controls the operation of the motor based on the operating instructions, e.g., controlling the start and stop, direction of rotation, angle of rotation, speed of rotation, etc. of the motor. The control button 50 may be provided at any suitable location on the swivel seat that facilitates the pressing by a person, optionally the control button 50 is provided on one side of the seat back 21 in the length direction, and optionally at an upper portion of the side.

It should be understood that the seat body 20 is not limited to being pivotally connected to the legs 10 near the intersection of the back 21 and seat 22 at the sides thereof, but may be pivotally connected to the legs 10 at other suitable locations, while ensuring the overall stability and balance of the swivel seat.

The turnover mechanism 40 may further include a positioning means for positioning the seat main body 20 when the seat main body 20 is turned over to a predetermined angle. For example, the positioning means may be a retractable latch provided at a predetermined position on the inner side of the leg 10, and when the seat body 20 is rotated to a desired position (desired position of the seat body 20), a latch engaging portion formed as a notch provided at the side of the seat body 20 is just engaged with the retractable latch, thereby positioning the seat body 20 at the desired position. More specifically, initially, the retractable latch is not in contact with the seat main body 20 and is in the extended state; as the seat body 20 rotates, the retractable latch retracts before contacting the seat body 20, so that the retractable latch is interposed between the side of the leg and the seat body 20, and the seat body 20 may continue to rotate; when the seat body 20 is rotated to a desired position, the retractable latch is just aligned with the latch engaging portion of the side of the seat body 20, the retractable latch is changed from the retracted state to the extended state, and is engaged in the latch engaging portion formed as a notch, thereby positioning the seat body 20 at the desired position. It will be appreciated that the positioning device is not limited to the above-described configuration, but may be of any suitable configuration.

Each seating (reclining) surface (front) of the back 21 and seat 22 may be formed as an ergonomically curved surface. Optionally, a chamber may also be provided inside the back 21 and/or seat 22 to house batteries, motors, control circuitry, etc.

The swivel seat may be a seat adapted for seating one or more persons, and in the present embodiment, the swivel seat is a seat adapted for seating two persons. As shown in fig. 2, a solar power generation panel 30 is disposed on the back surface of the seatback 21. Alternatively, the solar power generation panel 30 is detachably attached to the back surface of the seatback 21. Alternatively, the back surface of the seatback 21 is designed to be a curved surface, and the solar power generation panel 30 is a flexible solar power generation panel arranged to follow the curved surface. Fig. 4 shows a packaging structure of a flexible solar power generation panel on the back surface of the chair back 21 of the swivel chair of the present embodiment, and the flexible solar power generation panel sequentially comprises a first packaging adhesive film 31, a chip 32, a second packaging adhesive film 33, a butyl adhesive layer 34 and a transparent front plate 35 from the back surface layer 21b of the chair back 21. Alternatively, the chip 32 has a weak photovoltaic property, and alternatively is a CIGS chip having a good weak photovoltaic property, and can generate power even when the swivel seat is placed in a place where sunlight is weak, such as a shade of tree. It should be understood that the back surface of the seat back 21 may also be designed as a flat surface, and accordingly, the solar power generation panel is laid flat on the back surface of the seat back 21. It is to be understood that the solar panel may also be a rigid solar panel and have an encapsulation structure similar to that of the flexible solar panel described above.

Alternatively, the swivel seat is provided with a storage battery (not shown), which may be electrically connected to the solar power generation panel 30 and the reclining mechanism 40, for storing the electric power generated by the solar power generation panel 30 and supplying the stored electric power to the reclining mechanism 40. Alternatively, the battery may be embedded inside any of the legs 10, the back 21 and the seat 22. Alternatively, the battery may be provided outside the swivel seat, for example, buried under the ground near the swivel seat, or placed directly on the ground, or the like. Alternatively, the battery may be incorporated into the municipal power grid or connected to a nearby street light to provide power to the street light.

The swivel seat may be provided with a charging interface 60, such as a USB interface or the like, which facilitates the charging of the person at rest. Optionally, charging interface 60 is electrically connected to a battery. The charging interface 60 may be provided at any location on the swivel seat that facilitates charging. For example, in the case where the swivel seat is a two-person seat, one charging interface 60 (only one of which is shown in the drawing) may be provided on each of both sides (in the longitudinal direction) of the seatback 21 of the swivel seat.

Fig. 1 and 2 show perspective views of a seating mode of an example of the swivel seat in a desired position of the seat main body 20 described above, and fig. 3 shows a perspective view of a power generation mode of another example of the swivel seat in a desired position of the seat main body 20 described above. At ordinary times, in the case where no one is seated, the swivel seat is in the power generation mode shown in fig. 3 in which the back surface of the seatback 21 faces upward, and preferably vertically faces upward. Specifically, in the power generation mode, when the back surface of the seatback 21 is a flat surface, the flat surface is substantially parallel to the ground; when the back surface of the seatback 21 is curved as shown in the figure, both side end portions in the height direction of the seatback 21 (the direction substantially parallel to the ground in fig. 3) are substantially on the same horizontal line. The arrangement of the power generation mode with the back of the chair back 21 facing vertically upward can ensure that the solar power generation panel 30 effectively receives sunlight without being blocked no matter how the installation direction of the swivel chair is, thereby ensuring the normal power supply and charging of the swivel chair. For example, the solar power generation panel 30 of the present embodiment can receive sunlight when the sunlight is incident at any angle, as compared with the case where the solar power generation panel is substantially perpendicular to the ground or inclined at a large angle with respect to the ground, thereby maximizing the reception efficiency of the sunlight.

In addition, in the power generation mode, the front surface of the seat 22 faces downward, so that the solar power generation panel is not only exposed to more sunlight, but also the seat 22 is prevented from being directly irradiated by sunlight, and thus, when a person sits on the seat, the temperature of the seat 22 is not too high. In addition, the seating surface is less prone to ash or other soiling during the power generation mode.

In the power generation mode, by positioning the seat main body 20 by providing the positioning means described above, it is possible to ensure that the swivel seat is stably in the power generation mode.

When a person wants to sit on the swivel seat, the push button 50 provided on the swivel seat may be pressed, the push button 50 controls the operation of the turnover mechanism 40 through a control circuit (circuit system), so that the swivel seat is swiveled from the power generation mode to the sitting mode, and the swivel seat is positioned in the sitting mode by providing the above positioning means to increase the stability when sitting.

In the seating mode, the front surface (i.e., the surface that contacts the occupant) of the seat 22 faces upward, and the seat 22 is parallel to the ground, or the seat 22 is tilted upward from the side of the seat 22 adjacent to the seatback 21 toward the side away from the seatback 21, which provides a more comfortable seating experience for the occupant. When the person leaves, the button 50 can be pressed again to return the swivel seat from the seating mode to the power generation mode, and optionally positioned in the power generation mode by the positioning means.

Therefore, the seat main body 20 can be controlled to rotate by the button, thereby switching the swivel seat between the seating mode and the power generation mode. Alternatively, when the swivel seat is swiveled from the seating mode to the power generation mode, the seat main body 20 is swiveled by slightly more than 90 degrees about the horizontal axis with respect to the leg support 10 so that the back surface of the seatback 21 faces upward; when the swivel seat is swiveled from the power generation mode back to the seating mode, the seat main body 20 swivels back about the horizontal axis in the direction opposite to the aforementioned swivel direction.

Alternatively, the power generation mode and the seating mode are preset postures, the seat can be directly positioned to one of the power generation mode and the seating mode by pressing the button 50 once, and the seat can be positioned to the other of the power generation mode and the seating mode by pressing the button 50 again, without the need for a person to control the posture of rotation by the time of pressing the button 50, thereby ensuring the one-key flip positioning of the swivel seat, avoiding the adverse posture of the swivel seat from affecting the power generation effect, the seating stability, and the like.

Alternatively, a pressure sensor for sensing the weight of the seat main body 20 or the pressure applied to the seat main body 20 is installed on the swivel seat, and the activation of the turnover mechanism 40 is restricted when the weight or the pressure is sensed to exceed a predetermined value. That is, upon sensing that the weight or pressure exceeds a predetermined value, control is performed by the control circuit so that the motor does not rotate and/or the positioning device is not released even if the control button 50 is pressed at this time. Accordingly, an audible or visual alarm may be provided on the swivel seat to alert the user to remove the item and then activate the turnover mechanism 40.

The leg 10 and the seat body 20 may be made of conventional materials such as metal, engineering plastic, wood, etc., and the leg 10 and the seat body 20 may be made of the same or different materials. For example, the leg 10 may be made of a metal material, and the seat main body 20 may be made of an engineering plastic.

Besides the charging interface 60 powered by the solar panel, the swivel seat can be provided with other components or devices powered by the solar panel, such as an electric fan, an LED lamp, a display screen, a sound reproduction device, a massage device, an electric blanket electrically connected with a storage battery, and a light bar for identifying the seat at night, so as to meet various use requirements of people.
