Embodiments of the present disclosure will be described in detail hereinafter in conjunction with accompanying drawings to allow one of ordinary skill in the art to understand the present disclosure more clearly, in which:
The technical solutions of the embodiments will be described in a clearly and fully understandable way in connection with the drawings related to the embodiments of the disclosure. Apparently, the described embodiments are just a part but not all of the embodiments of the disclosure. Based on the described embodiments herein, those skilled in the art can obtain other embodiment(s), without any inventive work, which should be within the scope of the disclosure.
Unless otherwise defined, all the technical and scientific terms used herein have the same meanings as commonly understood by an ordinary skill in the art to which the present disclosure belongs. The terms, such as “first,” “second” or the like, which are used in the description and the claims of the present application, are not intended to indicate any sequence, amount or importance, but for distinguishing various components. Also, the terms, such as “a/an,” “one,” or the like, are not intended to limit the amount, but for indicating the existence of at lease one. The terms, such as “connect/connecting/connected,” “couple/coupling/coupled” or the like, are not intended to define a physical connection or mechanical connection, but may include an electrical connection/coupling, directly or indirectly. The terms, such as “On,” “under,” or the like, are only used to indicate relative position relationship, and when the position of the object which is described is changed, the relative position relationship may be changed accordingly.
The inventors notice that mobile equipment protective case usually comprises a protective case body. The protective case body can be disposed closely in the housing and/or display screen of the mobile equipment to prevent the housing and/or display screen of the mobile equipment from being scratched by hard objects. Furthermore, since the storage battery power of the mobile equipment is limited, which is insufficient to meet the requirement of users being outdoor or travel for a long time. A solar charging device is disposed in the mobile equipment protective case body to charge or continuously supply power to the mobile equipment, so as to increase the standby time and usage time of the mobile equipment. However, the photovoltaic plate currently used in the solar charging device of the mobile equipment protective case has low received energy per unit area, and has low utilization efficiency of incident light, and it cannot meet the requirement of supplying power to the mobile equipment.
As shown in
In the embodiment of the present disclosure, by disposing the light collecting layer 3 on the protective cover plate 2 of the protective device 100 of mobile equipment, the light collecting layer 3 refracts the incident light 200 and guides the incident light 200 to the photovoltaic layer 4, to improve utilization rate of the incident light 200.
For example, the light collecting layer 3 and the solar photovoltaic layer 4 can be arranged on a part region of the protective cover plate 2, or all region of the protective cover plate 2, or the body of whole protective device 100 of mobile equipment. According to different material of the protective cover plate 2, the light collecting layer 3 and the solar photovoltaic layer 4 can be arranged on the protective cover plate 2 in different manners.
For example, as shown in
For example, as shown in
In the cross-section views of the protective cover plate 2 shown in the
For utilizing the electrical energy output by the solar photovoltaic layer 4, the protective device of mobile equipment of the embodiment of the present disclosure further comprises an integrated circuit 10 and a charging component 20. As shown in
For example, the solar photovoltaic layer 4 can directly be attached on the protective cover plate 2, or the solar photovoltaic layer 4 can also be formed on the protective cover plate 2 by using a plasma enhanced chemical vapor deposition (PECVD) process or printing method. Furthermore, the light collecting layer 3 of the present embodiment can occupy a part region of the protective cover plate 2, as shown in
It should be noted that the protective cover plate 2 can be a part of the housing of the protective device of mobile equipment, and is made of same material as the housing of the protective device of mobile equipment; or can be a separate plate body that is formed with material different from that of the housing of the protective device of mobile equipment, and the plate body is embedded in or attached to the housing of the protective device of mobile equipment.
The light collecting layer is provided on the protective cover plate of the protective device of mobile equipment to guide the incident light to the solar photovoltaic layer, so that the utilization efficiency of the incident light is improved, and the capability of the protective device of mobile equipment with solar charging function supplying power to the mobile equipment and continuously charging the mobile equipment is enhanced.
The described above are only illustrative embodiments and implementations for explaining the present disclosure, and the present disclosure is not intended to limited thereto. For one of ordinary skill in the art, various modifications and improvements may be made without departing from the spirit and scope of embodiments of the present disclosure, and all of which should fall within the protection scope of the present disclosure. The scope protected by the present disclosure is defined by the claims.
