Referring to
In one embodiment, the connection structure 500 includes a connection negative terminal and a connection positive terminal. The connection negative terminal is a hole 520. The connection positive terminal is a protruding structure 510 (as shown in
In sunny days, after the sunshade umbrella is unfolded, the solar cell component 400 may be mounted to the umbrella body 100 through the connection structures 500, thereby converting solar energy into electrical energy and then supplying power to an electrical device through the current output structure without an external power source. At night or in rainy days, or in weak light environment in which the solar cell component 400 cannot carry out effective photoelectric conversion, the solar cell component 400 can be removed away from the umbrella body 100 by disassembling the connection structures 500, thereby preventing service life of the solar cell component 400 from being shorten due to bad weather. In addition, if the solar cell component 400 is non-detachably fixed to the umbrella body 100, after the utilization of the sunshade umbrella, it is difficult to fold up the umbrella body 100 as the umbrella body 100 is supported by the solar cell component 400, and it is not convenient for use and management; while in the sunshade umbrella provided in some embodiments of the present disclosure, the solar cell component 400 can be removed away from the umbrella body 100 in an unused state, which is convenient for folding up the umbrella body 100 and maintenance of the solar cell component 400.
Specifically, referring to
Specifically, in order to facilitate mounting of the solar cell component 400 on the umbrella body 100, the solar cell component 400 includes a central connection portion 420 and a solar cell unit 410. The solar cell unit 410 is detachably mounted to the central connection portion 420 through detachable engagement between the connection structures 500 (i.e., detachable engagement between a third connection structure 500 disposed on the solar cell unit 410 and a fourth connection structure disposed on the central connection portion 420). The central connection portion 420 is connected with the umbrella body 100 through the connection structure 500 (i.e., the second connection structure).
One connection structure 500 such as the second connection structure may be disposed on one surface of the central connection portion 420 for engaging with the umbrella body 100, and may engage with one connection structure 500 such as the first connection structure on the umbrella body 100 by means of mutual insertion. One connection structure 500 such as the fourth connection structure may be disposed at a lateral side of the central connection portion 420 for engaging with one connection structure 500 such as the third connection structure on the solar cell unit 410.
Further, as shown in
Further, as shown in
Each of the central connection portion 420 and the substrate 430 may be a hollow structure for accommodating circuits, thereby protecting the circuits.
Specifically, in order to improve photoelectric conversion efficiency of the solar cell unit 410 and ensure providing enough power, there may be two or more solar cell units 410. The quantity of the solar cell units 410 may be varied and may be set according to the size of the umbrella body 100 and power consumption of the electrical device, which are not specifically limited.
Further, referring to
In order to enable the sunshade umbrella of some embodiments of the present disclose to provide external power supply when the solar cell component 400 cannot carry out effective photoelectric conversion, the sunshade umbrella may further include a battery 304. The battery 304 may be disposed in the umbrella handle 300. The battery 304 is coupled to the solar cell component 400. The battery can store surplus electricity generated by the solar cell component 400. Thus, electricity demands of the electricity device in various weather conditions can be satisfied.
It should be noted that, in order to adjust the current generated by the solar cell component 400 through photoelectric conversion into a stable direct current so as to ensure normal operation of the electrical device, a voltage regulator circuit 306 may be disposed in the umbrella handle 300. The voltage regulator circuit 306 is coupled to the solar cell component 400.
It can be understood that the solar cell component 400 may be coupled to the battery 304, the current output structure 302 and the voltage regulator circuit 306 through the wire 301. In order to protect the wire, the umbrella rod 200 may be a hollow structure for accommodating the wire therein.
It should be noted that, the first connection structure, the second connection structure, the third connection structure, the fourth connection structure, the fifth connection structure, the sixth connection structure, the seventh connection structure and the eighth connection structure may have the same structure and connection mode, for example, they may employ the structure and connection mode shown in
In the sunshade umbrella according to some embodiments of the present disclosure, the presence of the solar cell component 400 enables the sunshade umbrella to provide power supply. Meanwhile, the solar cell component can be removed away from the umbrella body in an unused state, which is convenient for folding up the umbrella body and maintenance of the solar cell component.
Based on the embodiments shown in the drawings, the structure, characteristics and effect of the present disclosure are explained in detail. The above are merely the optional embodiments of the present disclosure and shall not be used to limit the scope of the present disclosure. It should be noted that, a person skilled in the art may make improvements and modifications without departing from the principle of the present disclosure, and these improvements and modifications shall also fall within the scope of the present disclosure.
