Description

Technical Field

[0001] This application relates to the field of charging equipment technology, and more particularly to a charging device. Background Technology

[0002] Charging devices typically feature a double-layered casing to prevent excessive surface temperature and ensure a better user experience. This double-layered structure includes an inner shell and an outer shell, with the outer shell fitted over the inner shell. The outer shell is often made of a transparent material to enhance the product's aesthetics. However, in existing technologies, to achieve relative fixation of the inner and outer shells, positioning posts are typically placed on the inner wall of the outer shell, and corresponding positioning slots are created on the inner shell. These interlocking mechanisms prevent displacement of the outer shell. But when using a transparent outer shell, the internal positioning structure is directly exposed, interfering with the visual integrity of the casing surface. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a charging device, comprising an electrical connection portion, an electronic component module, a first housing and a second housing disposed opposite to each other along a first direction, and a circumferential housing surrounding the outer periphery of the first housing and the second housing; the first housing, the second housing, and the circumferential housing together form a receiving cavity, and the electronic component module is disposed within the receiving cavity; at least one of the first housing and the second housing is provided with the electrical connection portion, the electrical connection portion being electrically connected to the electronic component module and exposed to the outside;

[0005] It also includes a transparent outer shell, which includes an interconnected shell body and an extension; the shell body is at least partially fitted onto the outer surface of the circumferential shell; the extension extends toward the interior of the receiving cavity and forms an edging structure around the circumferential shell; a first positioning part is provided at one end of the extension away from the shell body; a second positioning part is provided on the inner wall of the receiving cavity, and the second positioning part is connected to the first positioning part.

[0006] Alternatively, the extension forms a bent structure with the shell body, and the end of the extension away from the shell body is located inside the receiving cavity.

[0007] Alternatively, the first positioning part is a positioning post, which protrudes from one end of the extension part away from the shell body and extends along a first direction; the second positioning part is a positioning groove, and the positioning post is inserted into the positioning groove.

[0008] Alternatively, the circumferential housing may have a support portion corresponding to its edge, the support portion protruding from the inner wall of the receiving cavity, and the positioning groove disposed on the support portion.

[0009] Alternatively, the shell body is perfectly matched in shape and size with the circumferential shell, so that the circumferential shell is completely housed within the shell body.

[0010] Alternatively, the circumferential housing is provided with a first mounting hole corresponding to the first housing, the extension surrounds and forms the first mounting hole, the first mounting hole communicates with the receiving cavity, and the first housing is provided at the first mounting hole.

[0011] Further optionally, the electrical connection portion includes a first port, the first housing has a first through hole, the electronic component module includes a first circuit board, one end of the first port is disposed in the first through hole, and the other end is connected to the first circuit board.

[0012] Further optionally, the electrical connection portion includes a second port, the first housing is provided with a second through hole, the electronic component module includes a second circuit board, one end of the second port is disposed in the second through hole, and the other end is connected to the second circuit board.

[0013] Alternatively, the first circuit board is disposed along the first direction, the second circuit board is disposed along the second direction, the first direction is perpendicular to the second direction, and the first circuit board and the second circuit board are perpendicularly connected.

[0014] Alternatively, the second port is disposed along the first direction, and the circumferential housing has a support platform protruding on one side corresponding to the receiving cavity. The second circuit board is disposed on the support platform to restrict the movement of the second circuit board along the first direction.

[0015] Further optionally, the circumferential housing is provided with a second mounting hole corresponding to the second housing, the extension surrounds and forms the second mounting hole, the second housing is provided with the second mounting hole, and the second housing is provided with the second mounting hole.

[0016] Further optionally, the receiving cavity includes a first cavity and a second cavity, the first cavity being disposed corresponding to the circumferential housing, the second cavity being disposed corresponding to the second housing, and the first cavity communicating with the second cavity; the first circuit board being located in the first cavity and extending into the second cavity; the electrical connection portion further includes an elastic pin, the second housing having a third through hole, one end of the elastic pin being connected to the first circuit board, and the other end passing through the third through hole and protruding from the outer surface of the second housing; and / or, the second housing having a limiting portion corresponding to the second cavity, the first circuit board being engaged in the limiting portion to limit the displacement of the first circuit board.

[0017] The beneficial effects of this application are as follows: By providing a transparent outer shell on the outside of the circumferential housing, heat conducted by the circumferential housing can be effectively blocked when the user holds the charging device, significantly improving grip comfort and safety. Furthermore, by placing the first positioning part at the end of the extension, and having the extension engage with the second positioning part on the inner wall of the receiving cavity, the positioning structure can be completely hidden inside the receiving cavity while ensuring reliable fixation between the transparent outer shell and the circumferential housing. This makes it difficult for the user to directly observe the positioning component from the outside, thus maintaining the visual integrity and aesthetics of the transparent outer shell while ensuring assembly stability.

[0039] This application provides a charging device for supplying power to external electronic devices. The charging device can take various forms, including but not limited to power adapters (charging heads), power banks, or wireless charging devices. The charging device includes a housing and an electronic component module 2 disposed inside the housing; the electronic component module 2 typically includes circuit boards, resistors, capacitors, transformers, and control chips necessary for realizing power conversion and control functions. An electrical connection portion 1 is provided on the housing, which establishes an electrical connection with the internal electronic component module 2. Depending on the functional configuration, the electrical connection portion 1 can serve as a power input terminal, receiving external power to supply power to the charging device itself; or it can serve as a power output terminal, transmitting power to external electronic devices. Specific implementations of the electrical connection portion 1 include wired interfaces (such as USB ports like Type-C and Type-A), plug structures (such as foldable AC plugs), or built-in charging cables.

[0040] In one implementation, reference Figures 1 to 8 The charging device includes an electrical connection part 1, an electronic component module 2, and a housing. The housing has a receiving cavity 7, within which the electronic component module 2 is disposed. The electrical connection part 1 is provided on the housing, electrically connected to the electronic component module 2, and exposed to the outside for connection with external electronic devices or an external power source. Specifically, the housing includes a first housing 3 and a second housing 4 disposed opposite each other along a first direction X, and a circumferential housing 5 surrounding the first housing 3 and the second housing 4. The first direction X is, for example, the length direction of the charging device. The circumferential housing 5 consists of the four side walls of the charging device. The first housing 3 and the second housing 4 are respectively disposed on opposite sides of the circumferential housing 5 along the first direction X, together forming the receiving cavity 7. At least one of the first housing 3 and the second housing 4 has an electrical connection part 1; for example, the first housing 3 has an electrical connection part 1, or the second housing 4 has an electrical connection part 1, or both have an electrical connection part 1.

[0041] Furthermore, the electronic component module 2 generates a large amount of heat during operation. When a user grasps the charging device, they typically grasp the circumferential housing 5 of the charging device. The charging device also includes a transparent outer shell 6, which comprises a shell body 61 and an extension 62 connected to each other. The shell body 61 is at least partially fitted onto the outer surface of the circumferential housing 5 to block the heat of the circumferential housing 5 and improve the user experience. The extension 62 extends toward the interior of the receiving cavity 7 and forms a rim structure around the circumferential housing 5. A first positioning part 63 is provided at the end of the extension 62 away from the shell body 61. A second positioning part 51 is provided on the inner wall of the receiving cavity 7, and the second positioning part 51 is connected to the first positioning part 63.

[0042] By placing the first positioning part 63 at the end of the extension part 62, and the extension part 62 engaging with the second positioning part 51 on the inner wall of the receiving cavity 7, the positioning structure can be completely hidden inside the receiving cavity 7 while ensuring reliable fixation between the transparent outer shell 6 and the circumferential shell 5. This makes it difficult for the user to directly observe the positioning component from the outside, thereby maintaining the visual integrity and aesthetics of the transparent outer shell 6 while ensuring assembly stability.

[0043] In one implementation, specifically as follows: Figure 2 and Figure 6 As shown, the extension 62 and the shell body 61 form a bent structure, the bent structure corresponding to the edge of the circumferential shell 5, so as to wrap the edge of the circumferential shell 5; and the end of the extension 62 away from the shell body 61 is located in the receiving cavity 7, so that the connecting seam between the transparent shell 6 and the circumferential shell 5 is built into the receiving cavity 7, so that dirt, water and the like are difficult to enter between the transparent shell and the circumferential shell 5 through the connecting seam. In addition, the bent structure can further fix the transparent shell 6 to the circumferential shell 5, so that the two are not easy to separate.

[0044] In one implementation, reference Figure 2 , Figure 5 and Figure 6 The first positioning part 63 is a positioning post, with an extension 62 protruding from one end of the positioning post away from the shell body 61, and the positioning post extends along the first direction X; the second positioning part 51 is a positioning groove, and the positioning post is inserted into the positioning groove. The positioning post and positioning groove facilitate the assembly of the transparent shell 6 and the circumferential shell 5, and the positioning post's extension along the first direction X facilitates production and assembly. In other embodiments, the first positioning part 63 and the second positioning part 51 can be a mutually cooperating snap-fit ​​structure, which is not limited here.

[0045] Furthermore, specifically as follows Figure 7 As shown, a support portion 52 is provided on the corresponding edge of the circumferential housing 5. The support portion 52 protrudes from the inner wall of the receiving cavity 7, and a positioning groove is provided on the support portion 52. This provides support for the wall of the positioning groove and avoids damage to the positioning groove.

[0046] In one implementation, such as Figure 2 As shown, the shell body 61 is perfectly matched in shape and size with the circumferential shell 5 so that the circumferential shell 5 is completely contained within the shell body 61, ensuring that the circumferential shell 5 can be completely covered by the transparent shell 6 for effective heat insulation. In other embodiments, the shell body 61 may cover part of the circumferential shell 5, or the shell body 61 may cover both the circumferential shell 5 and the second shell 4; this is not a unique limitation.

[0047] In one implementation, such as Figure 3 As shown, the circumferential housing 5 is located at the first mounting hole 54 corresponding to the first housing 3. The extension 62 surrounds and forms the first mounting hole 54, which communicates with the receiving cavity 7. The first housing 3 is located at the first mounting hole 54. The first housing 3 abuts against the extension 62, forming a connection between the transparent outer shell 6 and the first housing 3, making the overall structure of the charging device compact.

[0048] In one implementation, Figures 1 to 4 As shown, the electrical connection part 1 includes a first port 11, the first housing 3 has a first through hole 31, the electronic component module 2 includes a first circuit board 21, one end of the first port 11 is located in the first through hole 31, and the other end is connected to the first circuit board 21. The first port 11 is, for example, Type-A, and extends along a first direction X and is connected to the first circuit board 21. The plug of the external cable can be inserted into the first port 11.

[0049] Furthermore, the electrical connection part 1 includes a second port 12, the first housing 3 has a second through hole 32, and the electronic component module 2 includes a second circuit board 22. One end of the second port 12 is located in the second through hole 32, and the other end is connected to the second circuit board 22. The second port 12 is, for example, Type-C, allowing different types of charging plugs to be connected by providing two different types of ports. The first circuit board 21 is arranged along the first direction X, and the second circuit board 22 is arranged along the second direction Y. The first direction X is perpendicular to the second direction Y, and the first circuit board 21 and the second circuit board 22 are perpendicularly connected; the two form a cross-shaped connection structure to facilitate the connection of two different types of ports on the same housing.

[0050] Furthermore, a support platform 53 protrudes from the side of the circumferential housing 5 corresponding to the receiving cavity 7, and the second circuit board 22 is disposed on the support platform 53 to restrict the movement of the second circuit board 22 along the first direction X. Since the first direction X extends along the length direction of the charging device, and the first port 11 also extends along the first direction X, when the user plugs in the first port 11, the force exerted is consistent with the extension direction of the first circuit board 21, making it less likely to damage the first circuit board 21. However, the second circuit board 22 is perpendicular to the first circuit board 21, and the second port 12 extends along the first direction X. When the user plugs in the second port 12, it is easy to squeeze the second port 12, causing displacement or breakage of the second circuit board 22. By providing the support platform 53 inside the circumferential housing 5, the second circuit board 22 is fixed between the support platform 53 and the first housing 3, restricting the displacement of the second circuit board 22 in the first direction X, and serving as a reinforcement of the second circuit board 22, it is less likely to break under external force.

[0051] In one implementation, such as Figure 2 and Figure 3 As shown, the circumferential housing 5 is provided at the second mounting hole 55 corresponding to the second housing 4, and the extension 62 surrounds and forms the second mounting hole 55. The second housing 4 is provided at the second mounting hole 55. The second housing 4 is connected to the extension 62, which helps to improve the compactness of the charging device structure.

[0052] Further details can be found in the following references. Figure 2 The receiving cavity 7 includes a first cavity 71 and a second cavity 72. The first cavity 71 is disposed corresponding to the circumferential housing 5, and the second cavity 72 is disposed corresponding to the second housing 4. The first cavity 71 and the second cavity 72 communicate to form the receiving cavity 7. The first circuit board 21 is located in the first cavity 71 and extends into the second cavity 72. The electrical connection part 1 also includes an elastic pin 13. The second housing 4 is provided with a third through hole 43. One end of the elastic pin 13 is connected to the first circuit board 21, and the other end passes through the third through hole 43 and protrudes from the outer surface of the second housing 4. The first circuit board 21 extends into the second cavity 72 to facilitate the electrical connection of the elastic pin 13.

[0053] like Figure 2 and Figure 8 As shown, the second housing 4 is provided with a limiting part 44 corresponding to the second cavity 72. The limiting part 44 is, for example, a limiting groove. The shape of the limiting groove matches the bottom end of the first circuit board 21. The first circuit board 21 is locked in the limiting part 44 to limit the displacement of the first circuit board 21 in the plane perpendicular to the first direction X, and can also limit the displacement of the first circuit board 21 along the first direction X.
