Technical Field

[0001] This application relates to the field of charging accessories, and in particular to the housing structure of a charging accessory. Background Technology

[0002] Charging accessories refer to various devices and components used to provide power to electronic devices such as mobile phones, tablets, and laptops. They mainly include charging heads, charging harnesses, wireless chargers, and power banks. These charging accessories are prone to overheating during high-power use.

[0003] In existing related technologies, to alleviate the heat generation problem of charging accessories, liquid cooling circulation pipes are usually installed inside the charging accessories. A refrigerant carries away the heat from heat-generating components (such as chips, batteries, and resistors) and dissipates the heat to the atmosphere in the heat dissipation zone. For example, utility model patent CN 221137686 U discloses a cooling charging harness and a charging cooling device having the same, including a fixed housing, a charging harness, and a cooling channel. By supplying coolant into the cooling channel, the cooling efficiency is improved.

[0004] Regarding the aforementioned technologies, the circulation of cooling channels requires external equipment (such as various circulation devices and air-cooling devices), which results in poor portability, inconvenience in use, and difficulty for individual users. Summary of the Invention

[0005] In order to increase the heat dissipation area of ​​the charging accessory and improve the heat dissipation effect, this application provides a shell structure for the charging accessory.

[0058] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0059] Example 1:

[0060] Embodiment 1 of this application discloses a housing structure for a charging accessory. In this application, a charging accessory refers to various devices that provide power to electronic devices, such as mobile phones, tablets, and laptops.

[0061] Reference Figure 1 and Figure 3 The charging accessory's outer casing structure includes a cooling outer casing 2 and an accessory body 1. Specifically, in Embodiment 1 of this application, the accessory body 1 is a rechargeable data cable for a smartphone.

[0062] The cooling outer shell 2 is tubular, with its two ends extending along the length of the accessory body 1 to both ends of the accessory body 1, and the material of the cooling outer shell 2 is flexible. An inner cavity 201 is formed inside the cooling outer shell 2, and the cross-section of the inner cavity 201 is closed. Specifically, in this embodiment, the material of the cooling outer shell 2 is silicone, and the cross-section of the inner cavity 201 is a closed circle.

[0063] Reference Figure 3The accessory body 1 is located inside the inner cavity of the cooling shell 2, and the cooling shell 2 is fitted onto the outer surface of the accessory body 1. A cooling chamber 202 is formed between the cooling shell 2 and the outer surface of the accessory body 1. The cooling chamber 202 extends along the length of the accessory body 1 to both ends of the accessory body 1, and is penetrated through both ends of the accessory body 1. A sealing block 21 is inserted and fitted into the end of the cooling chamber 202 to seal the cooling chamber 202. The cooling chamber 202 is filled with a thermally conductive medium with a thermal conductivity greater than 0.05 W / (m·K) to quickly disperse the heat emitted from the surface of the accessory body 1 to all parts of the thermally conductive medium, thereby increasing the heat dissipation area and improving the heat dissipation effect. The cooling shell 2 is flexible, the thermally conductive medium is liquid, and the thermally conductive medium is insulating, so that individual users can bend the accessory body 1 and reduce damage to the charging accessory in case of accidental leakage of the thermally conductive medium.

[0064] The implementation principle of the outer shell structure of a charging accessory in Embodiment 1 of this application is as follows: When the wire harness heats up, the heat is directly transferred to the heat-conducting medium in the cooling chamber 202. The heat-conducting medium increases the heat dissipation area, allowing the heat from the more easily heated end near the wire harness plug to be transferred more quickly to the middle of the wire harness. This enables the heat to be dissipated to the outside of the wire harness more promptly, thereby ensuring heat dissipation. Furthermore, the heat-conducting medium covering the outer periphery of the wire harness does not rely on an external circulation device, making it convenient for individual users.

[0068] The accessory body 1 is located inside the cavity of the cooling shell 2, and the cooling shell 2 is fixedly connected to the outer surface of the accessory body 1. The cooling shell 2 can be integrally connected to the accessory body 1 or fixedly connected to the accessory body 1 by assembly. Specifically, in embodiment 2, the cooling shell 2 is fixed to the outer surface of the accessory body 1 by adhesive assembly to reduce the molding difficulty of the cooling shell 2. A cooling chamber 202 is formed between the cooling shell 2 and the outer surface of the accessory body 1. The cooling chamber 202 extends along the length direction of the accessory body 1 to the pin end and the wiring end of the accessory body 1, and the cooling chamber 202 is closed at both the pin end and the wiring end of the accessory body 1 by the cooling shell 2.

[0069] Example 3:

[0071] Reference Figure 6 and Figure 7 The accessory body 1 is a charging pack, and the cooling shell 2 is tubular in shape and made of metal. Both ends of the cooling shell 2 extend to the two ends of the accessory body 1. An inner cavity 201 is formed inside the cooling shell 2, and the cross-section of the inner cavity 201 is closed. Specifically, in this embodiment, the cooling shell 2 is made of aluminum alloy, and the cross-section of the inner cavity 201 is a closed rectangle.

[0072] Reference Figure 4 The accessory body 1 is located inside the inner cavity of the cooling shell 2, and the cooling shell 2 is fixedly connected to the outer surface of the accessory body 1. The cooling shell 2 can be integrally connected to the accessory body 1 or fixedly connected to the accessory body 1 by assembly. Specifically, in embodiment 2, the cooling shell 2 is fixed to the outer surface of the accessory body 1 by adhesive assembly to reduce the molding difficulty of the cooling shell 2. A cooling chamber 202 is formed between the cooling shell 2 and the outer surface of the accessory body 1. The cooling chamber 202 extends along the length direction of the accessory body 1 to both ends of the accessory body 1, and the cooling chamber 202 is closed at both ends of the accessory body 1 by the cooling shell 2.

[0073] Reference Figure 7 The outer shell structure of the charging accessory also includes a heat-conducting component, which has a heat-absorbing end and a heat-dissipating end. There are two types of heat-conducting components, one of which is a first heat-conducting element 3, and the other is a second heat-conducting element 4.

[0074] The first heat-conducting element 3 is made of metal, preferably copper, and its heat-absorbing end and heat-dissipating end are respectively designated as a first heat-absorbing end 31 and a first heat-dissipating end 32. The first heat-absorbing end 31 is located inside the power bank and contacts the power bank's heating element. In this application, the heating element refers to an internal component of the charging accessory that generates significant heat during operation, such as an integrated circuit component, an energy storage component, a light-emitting component, a resistive component, and an electrothermal component. Therefore, by contacting the first heat-conducting element 3, the heat generated by the heating element can be transferred to the first heat-conducting element 3. Specifically, in this embodiment, the first heat-absorbing end 31 contacts the chip inside the power bank to absorb the heat generated by the chip during operation.

[0075] In addition, to ensure tight contact between the first heat-absorbing end 31 and the heating element, thermally conductive silicone grease can be filled between the first heat-absorbing end 31 and the heating element to reduce the gap between the first heat-absorbing end 31 and the heating element, thereby ensuring thermal conductivity.

[0076] The first heat dissipation end 32 is located on the outside of the power bank, and the surface area of ​​the first heat dissipation end 32 is larger than the surface area of ​​the first heat absorption end 31. The first heat dissipation end 32 is in contact with the heat-conducting medium in the cooling chamber 202, so as to transfer the heat in the first heat-conducting element 3 to the heat-conducting medium, thereby expanding the heat dissipation area through the heat-conducting medium and improving the heat dissipation effect of the cooling structure.

[0077] The second heat-conducting element 4 is made of metal, preferably copper. The heat-absorbing end and heat-dissipating end of the second heat-conducting element 4 are respectively designated as a second heat-absorbing end 41 and a second heat-dissipating end 42. The second heat-absorbing end 41 has several battery cavities 411, and several energy storage batteries of the power bank are located within each battery cavity 411. The gap between the cavity wall of the battery cavity 411 and the energy storage battery is filled with thermally conductive filler, so that the heat generated by the energy storage battery during charging and discharging can be directly transferred to the second heat-absorbing end 41 or transferred to the second heat-absorbing end 41 through the thermally conductive filler.

[0078] The second heat dissipation end 42 is provided in several ways, and each of the several second heat dissipation ends 42 is in contact with the jacket shell and / or the heat-conducting medium, so as to transfer the heat in the second heat-conducting element 4 through the jacket shell to the heat-conducting medium, or directly to the heat-conducting medium, thereby expanding the heat dissipation area through the heat-conducting medium and thus improving the heat dissipation effect of the cooling structure.

[0079] Specifically, in the embodiments of this application, the cross-sections of the plurality of second heat dissipation ends 42 are all arranged in a "T" shape, and the second heat dissipation ends 42 are all located inside the cooling chamber 202, so that the plurality of second heat dissipation ends 42 can directly transfer heat to the heat conduction medium inside the cooling chamber 202.

[0080] The implementation principle of the cooling structure of a charging accessory in Embodiment 3 of this application is as follows: the heat of the internal chip of the power bank is transferred to the heat conduction medium through the first heat conduction element 3, and the heat of the internal battery of the power bank is transferred to the heat conduction medium through the second heat conduction element 4, so that the heat enclosed inside by the power bank shell is transferred to the heat conduction medium for heat dissipation.

[0081] Example 4:

[0082] Embodiment 4 of this application discloses a housing structure for a charging accessory, which, in addition to all the technical features of Embodiment 3, also includes the following technical features:

[0083] Reference Figure 8 The first heat dissipation end 32 has a heat conduction cavity 5, which extends toward the location of the first heat absorption end 31, so that the heat conduction medium can flow into the heat conduction cavity 5, thereby increasing the contact area between the first heat conduction element 3 and the heat conduction medium, so that the first heat conduction element 3 can transfer heat to the heat conduction medium.

[0084] Example 5:

[0085] Embodiment 5 of this application discloses a housing structure for a charging accessory. The main difference from Embodiment 3 is that the first heat dissipation end 32 of the first heat-conducting element 3 contacts the heat-conducting medium in the cooling chamber 202 and is fixedly connected to the cooling housing 2, and the second heat dissipation end 42 of the second heat-conducting element 4 also contacts the heat-conducting medium in the cooling chamber 202 and is fixedly connected to the cooling housing 2.

[0086] The implementation principle of the cooling structure of a charging accessory in Embodiment 5 of this application is as follows: by directly transferring some of the heat to the cooling shell 2 made of aluminum alloy, the heat dissipation effect is further increased.

[0087] Example 6:

[0088] Embodiment 5 of this application discloses a housing structure for a charging accessory, which, in addition to all the technical features of Embodiment 1, also includes the following technical features:

[0089] The jacket housing is light-transmitting and preferably colorless and transparent. The heat-conducting medium contains indicator particles made of thermochromic powder. The color of the indicator particles changes when the temperature of the heat-conducting medium changes, so that individual users can judge the operating temperature of the charging accessory based on the color of the indicator particles.
