Description

Smart bench {Smart bench}

The present invention relates to a smart bench. More specifically, it relates to a smart bench configured to generate electric power by mounting a solar cell on the front and/or rear surface of the backrest, and to consume the produced electric power in the seat.

Benches are installed in places where people pass, such as parks, amusement parks, and walking trails, to provide people with a resting place.

Recently, such a bench produces power from sunlight to provide various functions, and this type of bench is also called a 'solar bench'.

The conventional solar bench is configured in a form in which a solar cell collecting plate is separately provided on a conventional bench or a solar cell is mounted on a pedestal.

Figure 1 (a) is a view illustrating the prior art of a form in which a solar cell condensing plate is separately provided on a bench. However, when the bench and the solar cell condensing plate are separately configured, there is a limitation in miniaturization, maintenance is difficult, and the unit price is increased.

Accordingly, a technology for mounting a solar cell on a pedestal has been developed. 1B is a view illustrating a conventional solar bench in which a solar cell is mounted on a pedestal. As shown in (b) of FIG. 1 , weight reduction and miniaturization are achieved by mounting the solar cell on the pedestal.

However, since solar cells are usually configured in series, there is a problem in that power generation using sunlight is completely stopped when a user is seated on a pedestal. In order to solve this problem, a large number of small-sized solar cells must be connected in parallel for construction.

It is desirable to support That is, the solar cell support member 14 is formed with a section flatly supported toward the open surface. In other words, the solar cell support member 14 is preferably manufactured in a concave-convex shape. In this way, the CIGS formed on the front and rear surfaces can be fixed flatly through the structure in which the flat irregularities are repeated. In addition, a slit S through which CIGS is bent and passed is formed at one end of the solar cell support member 14 . The solar cell 13 may be configured using one CIGS through the slit S. On the other hand, at one end of the solar cell support member 14, a groove (H) is formed in which the charging circuit formed integrally with the solar cell 13 is accommodated. In this way, after removing the front or rear cover 12, insert half of the solar cell 13 to the opposite side through the slit (S), fold the solar cell 13 at the slit (S) position, and then cover Since the installation is completed by closing (12), the manufacturing process can be simplified, and there is an advantage of easy maintenance in the future.

Meanwhile, as shown in FIG. 6 , the backrest 10 preferably forms an angle in the range of 90° to 120° with the upper surface of the seat 20 according to the power generation efficiency of the solar cell 13 . At this time, the angle between the upper surface of the backrest 10 and the seat 20 can be adjusted depending on the installation location in consideration of the incident angle of sunlight, and since the solar cell 13 is formed on both the front and back surfaces of the backrest 10 , In consideration of this, the angle between the upper surface of the backrest 10 and the seat 20 may be adjusted.

On the other hand, the pedestal 20 is provided with a power consuming member 23 using the power supplied from the solar cell (13). In addition, the pedestal 20 may be provided with a sensor group connected to the power consuming member 23 and a controller for controlling the power consuming member 23 .

Here, the surface heating member or the surface cooling member includes equipment for heating or cooling the member itself, as well as heater equipment or ventilation equipment using wind.

On the other hand, as one of the sensor group, a temperature sensor may be installed at a specific location of the smart bench to measure the external temperature. That is, it is possible to control the surface heating member or the surface cooling member installed on the pedestal 20 by using the power supplied from the solar cell 13 in response to the external temperature. Meanwhile, the temperature of the surface heating member or the surface cooling member may be adjusted automatically or by a user operation in response to the external temperature measured by the temperature sensor.

In addition, in order to detect the part where the user is seated and to perform control corresponding thereto, it is preferable to install the sensor group and the control unit in the inner space of the backrest 10 or the seat 20 . In this case, the human body sensor 31 may be used as one of the sensor groups, and various sensors such as an infrared sensor, an ultrasonic sensor, and a load cell may be used as the human body detection sensor 31 . Meanwhile, FIG. 2 exemplifies a case in which the human body detection sensor 31 is formed at the lower end of the backrest 10 .

That is, the control unit may perform heating or cooling only for the corresponding position of the pedestal 20 through sensing of the portion where the user is seated. On the other hand, in the present embodiment, the case of controlling a region in which heating or cooling is performed through a sensor is described, but heating or cooling is performed on the corresponding position of the pedestal 20 corresponding to the region in which solar power is not generated. control may be made. To enable such control, it is preferable that the surface heating member or the surface cooling member be installed separately, and in particular, it will be preferable to separately install it corresponding to the position of the sensor.

As described above, the smart bench of the present invention can function as a power supply source for electronic devices, and can also charge electronic devices in a wired or wireless manner through a wired or wireless charger. In addition, by installing an LED module at the bottom of the pedestal 20, it is possible to perform a landscape lighting function at night.
