Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clear, the present application will be further described in detail with reference to the accompanying drawings.
The terminology used in the following examples is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification of this application and the appended claims, the singular forms "a", "an", "the" and "the" are intended to include the plural forms as well, such as "one or more", unless the context clearly indicates otherwise.
Reference throughout this specification to "one embodiment" or "some embodiments," or the like, means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Thus, appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," or the like, in various places throughout this specification are not necessarily all referring to the same embodiment, but rather "one or more but not all embodiments" unless specifically stated otherwise. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless expressly specified otherwise.
With the development of electronic device technology, the charging speed of the electronic device is also an index pursued by users and manufacturers. Therefore, the quick charging technology is applied to various electronic devices to reduce the charging time of the electronic devices. For example, in a charging process of a mobile terminal such as a mobile phone and a tablet computer, a quick charging technology is generally adopted. However, the quick charging technique also causes certain problems, for example, the charger heats up too fast to cause the housing to heat up faster, a situation of scalding hands may occur, and even a fire hazard may exist. In order to solve the above problems, the present application provides a charger housing, a charger, and an electronic device kit including the charger. The present application will be described in further detail with reference to the following drawings and examples.
The embodiment of the application provides an electronic device kit, which comprises an electronic device and a charger for charging the electronic device, wherein the charger is matched with the electronic device. Specifically, the charger and the electronic device may be connected wirelessly or in a wired manner. In a specific embodiment, the electronic device can be a smart phone, a tablet computer, a wearable device, a monitoring camera, or various cameras, and the like, which are not listed one by one in the present application.
Fig. 1 is a schematic structural diagram of a charger in an embodiment of the present application, and as shown in fig. 1, the charger includes a charger housing 1 and an electronic device 2, where the charger housing 1 has a receiving cavity 3 for the electronic device 2, and the electronic device 2 is disposed in the receiving cavity 3. The charger shell 1 is a phase-change heat storage shell, and the charger shell 1 is made of a phase-change heat storage material. Specifically, the phase change heat storage material is a solid-solid phase change heat storage material, that is, the phase change heat storage material can be kept in a solid state in the processes of heat absorption and heat release, and serves as a casing of the charger to accommodate the electronic device 2. When the charger works, the temperature of the internal electronic device 2 may rise rapidly, and the phase change heat storage shell can absorb and store the heat generated by the electronic device 2, so that the charger shell 1 is less affected by the heat generated by the internal electronic device 2. When the charger stops working or the power is low, the temperature around the phase change heat storage layer is reduced, and then the heat is gradually released. Therefore, the scheme can prevent the temperature of the charger shell 1 from rising rapidly, so that the user experience is improved, and the fire hazard is reduced. In addition, when the charger works, the charger may correspond to two charging modes, namely, a fast charging mode (including ultra-fast charging) and a normal charging mode, and when the charger is in the fast charging mode, the power is high, and the electronic device 2 heats quickly. The scheme absorbs heat generated by the quick charging mode, is favorable for prolonging the time of the quick charging mode, and improves the charging efficiency and the user experience of the charger. The charger in the scheme can be simple in structure and simple in manufacturing process.
In order to improve the heat-equalizing effect of the charger housing 1, the phase-change heat storage housing is further doped with a heat-conducting material, such as aluminum, copper, or graphite. The heat generated locally can be uniformly dispersed to the whole phase change heat storage shell, so that the condition that the local temperature of the charger shell 1 is heated too fast is reduced.

A cavity 13 is formed between the outer shell 11 and the inner shell 12, and a phase change heat storage layer 14 is arranged in the cavity 13.

In this embodiment, the charger housing 1 can not only absorb and store the heat generated by the electronic device 2, but also gradually release the stored heat when the charger stops working or the power is low. This scheme can reduce the temperature rising speed of charger casing 1, prevents the high temperature of charger casing 1. The phase change heat storage layer 14 in this scheme is arranged in the cavity 13 formed by the outer shell 11 and the inner shell 12, so that the phase change heat storage material can be isolated from the electronic device 2 in the charger. The insulation and voltage resistance of the phase-change heat storage material can be improved, and the difficulty of forming the phase-change heat storage layer 14 by the phase-change heat storage material can be reduced. Since the phase change thermal storage layer 14 is disposed in the cavity 13, the form of the phase change thermal storage layer 14 is not limited, and may be, for example, a glue, a powder, or a particle form. The phase-change heat storage material may be a solid-solid phase-change material, a solid-liquid phase-change material, or a liquid-gas phase-change material, and the application is not limited thereto.

In the embodiment shown in fig. 6, the heat conductive layer 121 is attached to the inner casing 12 of the charger housing 1 to rapidly disperse local heat to the whole charger housing 1, thereby reducing the concentration of heat. Specifically, when the heat conduction layer 121 is disposed, the heat conduction layer 121 may be disposed on a side of the inner shell 12 away from the outer shell 11, so that the heat conduction layer 121 is in contact with an electronic device that generates heat, and conducts heat quickly.
