Description

Technical Field

[0001] This utility model belongs to the technical field of charging interface structure, and in particular relates to a novel fixing structure and electronic equipment. Background Technology

[0002] USB Type-C is a USB interface standard that is smaller than USB Type-A and USB Type-B. Currently, many electronic devices use USB Type-C as their charging interface.

[0003] However, the current methods of fixing USB Type-C as the charging interface are often not robust enough. For example, the charging interface is soldered to the corresponding soldering point on the edge of the circuit board, and then the circuit board is directly fixed without further reinforcement of the charging interface. The small size of USB Type-C is more easily damaged. Every time the charging interface is plugged in or unplugged, the charging interface may deform or move relative to the circuit board. After repeated plugging and unplugging of the charging interface, the soldering of the charging interface on the circuit board may become loose, resulting in poor contact of the charging interface, or even making it impossible to use the charging interface for charging. Utility Model Content

[0025] The housing of the novel fixing structure is sealed and adapted to the top cover, so that only one end of the charging interface in the through hole of the novel fixing structure is exposed to the electronic device.

[0026] As can be seen from the above technical solutions, this embodiment has the following advantages:

[0027] The novel fixing structure of this application includes: a fixing steel sheet and a housing; the main body of the fixing steel sheet is strip-shaped; limiting portions extend on both sides of the first end of the main body of the steel sheet, and the limiting portions extending on both sides are bent in a first direction to form a first predetermined angle with the main body of the steel sheet; the second end of the main body of the steel sheet is bent in the first direction to form a second predetermined angle with the main body of the steel sheet, so that the main body of the steel sheet, the limiting portions extending on both sides, and the second end of the main body of the steel sheet form a receiving space adapted to accommodate a charging interface; the limiting portions extending on both sides are provided with barbs on the surface away from the receiving space, and the barbs are used to fasten and fix the fixing steel sheet accommodating the charging interface to the housing from the first direction.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0034] Please see Figure 1 The novel fixing structure of this embodiment includes: a fixing steel sheet 100 and a housing 200; wherein the main body 110 of the fixing steel sheet 100 is strip-shaped; and limiting portions 111 extend from both sides of the first end of the main body 110 of the steel sheet (e.g., Figure 2 , Figure 3The left limiting portion 111a and the right limiting portion 111b shown are bent in a first direction to form a first predetermined angle with the steel sheet body 110, for example, the first predetermined angle is 90 degrees. The second end 112 of the steel sheet body 110 is bent in the first direction to form a second predetermined angle with the steel sheet body 110, for example, the second predetermined angle is also 90 degrees, so that the steel sheet body 110, the limiting portions 111 on both sides, and the second end 112 of the steel sheet body 110 form a receiving space adapted to accommodate the charging interface 300. The limiting portions 111 on both sides are provided with barbs 111c on the surface away from the receiving space. The barbs 111c are used to fasten and fix the fixing steel sheet 100 accommodating the charging interface 300 to the housing 200 from the first direction. Specifically, the barbs 111c are interference-fitted with the charging port mounting side wall 211 in the housing 200.

[0035] For further details, please refer to the following: Figure 4 , Figure 5 In this embodiment, the housing body 210 of the novel fixed structure housing 200 is provided with a through hole 212 for mounting the charging interface 300; the limiting portions 111 extending on both sides are used to limit the first translational degree of freedom of the charging interface 300; the steel plate body 110 and the housing body 210 are used to limit the second translational degree of freedom of the charging interface 300; the second end 112 of the steel plate body 110 and the edge of the through hole 212 are used to limit the third translational degree of freedom of the charging interface 300. In a further embodiment, the second end 112 of the steel plate body 110 also has locking portions (e.g., Figure 2 , Figure 3 The left locking portion 112a and the right locking portion 112b shown can be locked onto the housing body 210 from the first direction, thereby restricting the movement of the fixed steel plate 100 in one or both directions of the third translational degree of freedom. For details, please refer to the relevant documentation. Figure 1In this embodiment, the first translational degree of freedom is the leftward and rightward movement of the steel plate body 110 perpendicular to the central axis L of the charging interface 300 and parallel to the surface plane of the steel plate body 110; the second translational degree of freedom is the upward and downward movement of the steel plate body 110 perpendicular to the central axis L of the charging interface 300 and the surface plane of the steel plate body 110; the third translational degree of freedom is the backward and forward movement along the central axis L of the charging interface 300. Specifically, in this embodiment, the first direction mentioned above is the downward movement direction, and the limiting part 111 and the locking part of the fixed steel plate 100 are installed towards the housing body 210 from the same direction, making assembly more convenient and faster. As can be seen, the fixing steel plate 100 of the novel fixing structure in this embodiment can fix the charging interface 300 in all translational degrees of freedom, so that the charging interface 300 can be stably connected to the housing 200. Compared with the prior art, which only solders the charging interface to the circuit board and then fixes the circuit board to the housing, the solution in this embodiment is more robust and reliable, can withstand more cycles of wire harness plugging and unplugging of the charging interface, reduces the possibility of loosening and poor contact of the charging interface, and thus extends the life of products using the charging interface. The novel fixing structure in this embodiment has a simple structure, fewer structural components, obvious cost advantages, and is convenient, quick and easy to assemble, and is robust and reliable.

[0036] Furthermore, in this embodiment, the housing body 210 of the new fixed structure housing 200 is provided with one or more sealing rings between the through hole 212 and the charging interface 300. The sealing ring is a waterproof rubber ring, which is used to seal the installation gap between the charging interface 300 and the housing body 210 at the through hole 212, so as to prevent external water vapor or water quality from entering the interior of the housing 200 through the through hole.

[0037] Furthermore, in this embodiment, the second end 112 of the steel sheet body 110 of the novel fixing structure is provided with a ribbon cable notch 112c. The ribbon cable notch 112c is used to facilitate the ribbon cable 400 connected to the charging interface 300 to pass through the fixing steel sheet 100 and extend to the rear to connect to the battery or circuit board. Preferably, the charging interface in this embodiment is a USB Type-C interface, especially a horizontal waterproof USB Type-C interface. The fixing steel sheet in this embodiment is preferably made of SUS316 material.

[0038] This embodiment also provides an electronic device, which includes the novel fixing structure mentioned in the above embodiments. Optionally, the electronic device is a wearable smart device (e.g., the main unit of a heart rate monitoring armband, the main unit of a heart rate monitoring chest strap, a wrist-worn wearable device, etc.), and the wearable smart device further includes: a top cover; the shell of the novel fixing structure and the top cover can be sealed and adapted to each other, so that only the charging interface end in the through hole of the novel fixing structure is exposed, so that the wearable smart device can meet the requirements of stable charging while also having high waterproof performance.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
