[0002] The main case is a shell structure used to protect circuit boards, such as mobile phones, watches, radio cases, etc. With the development of smart wearable devices, new requirements have been put forward for the main case. For example, products such as smart watches and smart eye masks require the main case to be small and thin. Especially for fabric and electronic fusion scenarios, a quick-detachable connection of the main case is often required, because the fabric part of the product needs to be washed, but the circuit board cannot be washed. Judging from the main cases of smart wearable products in the current industry, especially smart eye masks, they are often relatively thick, resulting in a poor wearing experience. It is understandable that for sleep products, whether the main case is thin and light has a significant impact on the user experience. Therefore, further improvement and optimization are needed. Summary of the invention

[0003] The purpose of the present invention is to provide an improved main casing structure in view of the deficiencies existing in the above-mentioned background technology, so that the main casing can be made particularly light and thin, and the space utilization rate in the main casing can be improved through appropriate arrangement of components and circuit boards, so as to maximize the battery capacity of the product, thereby improving the battery life, etc.

[0004] In order to achieve the above-mentioned object, the present invention provides an ultra-thin multi-contact quick-detachable main housing, comprising a housing, wherein a central area and two side areas located on both sides of the central area are arranged in the housing, and the thickness of the central area is greater than that of the side areas;

[0010] Furthermore, the side circuit board adopts a double-sided electronic component arrangement, with one side arranging electronic components with small thickness and the other side arranging electronic components with large thickness; the upper surface of the central circuit board is used to arrange electronic components, and the lower surface is connected to the shell and the contact connector female head.

[0011] Furthermore, the side circuit board and the central circuit board are both hard-flexible boards, and are connected to each other via a soft board portion.

[0012] Furthermore, the side circuit board and the central circuit board are integral flexible circuit boards, and the electronic component arrangement area is protected by local reinforcement or glue hardening.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0033] like Figure 1-Figure 3 As shown, an embodiment of the present invention provides an ultra-thin multi-contact quick-detachable main housing, including a shell 1, on the lower surface of which a female contact connector is arranged, which is matched with an independent male contact connector and can be plugged in. The female contact connector is integrated with the shell 1, including a main groove 2 and an anti-fool groove 3. The main groove 2 is used to accommodate the male contact connector when it is inserted, so as to further reduce the overall thickness. As a preferred embodiment, in this embodiment, a first magnet 4 is arranged in the main groove 2, preferably a ring-shaped nebium magnet with an anti-fool effect. Although this magnet is annular, it is divided into left and right half rings, and the two half rings have opposite polarities in the vertical direction to avoid the male contact connector from being plugged in reverse. A POGPIN connector 5 is arranged at the center of the first magnet 4. This connector has an ultra-thin and short spring pin with a gold-plated surface to ensure the reliability of contact.

[0034] The male seat of the contact connector includes a seat body 6, on which a second magnet 7 is arranged, and it is also preferred to use the aforementioned rubidium magnet with anti-foolproofing function. A gold-plated contact 8 is arranged in the center of the second magnet 7, which contacts and cooperates with the POGPIN connector 5 to achieve conduction. In addition, the seat body 6 is also provided with an anti-foolproofing plug-in block 9 corresponding to the anti-foolproofing groove 3, which can be inserted into the anti-foolproofing groove 3 to avoid reverse insertion of the male and female. The figure shows the bottom of the main housing after the female head of the contact connector is connected to the male seat of the contact connector. Therefore, the main housing provided in this embodiment uses a ring-shaped polarized magnet and an anti-foolproofing plug-in structure, which not only achieves anti-foolproofing during user use, but also achieves magnetic fixation with sufficient strength in a limited space.

[0035] In this embodiment, the housing 1 is configured as an arc shape as a whole, which is suitable for the needs of products such as smart eye masks and smart watches. Figure 4 As shown, a plurality of areas are provided inside the shell 1, including a central area and side areas on both sides of the central area. The thickness of the central area is thicker, and the thickness of the side area is thinner. Two side circuit boards 10 are respectively provided in the two side areas. Preferably, the side circuit board 10 adopts a double-sided electronic component arrangement, one side of which uniformly arranges electronic components with smaller thickness, and the other side uniformly arranges electronic components with larger thickness, thereby reducing the thickness of the side circuit board 10 as a whole and improving the integration. A central circuit board 11 is provided in the central area, and the POGPIN connector 5 is welded to the central circuit board 11 inside the shell 1 to fix and form an electrical connection. It should be noted that the upper surface of the central circuit board 11 is used to arrange other types of electronic components, and the lower surface is connected to the shell 1 and the POGPIN connector 5.

[0036] As a preferred embodiment, the side circuit board 10 and the central circuit board 11 in this embodiment are both hard-flex boards, and the connection between the three is through the soft board part of the hard-flex board, so they can bend to a certain extent with the housing 1. In other embodiments, the side circuit board 10 and the central circuit board 11 can also be a whole flexible circuit board (FPC), and the installation position of the electronic components can be reliable through local reinforcement or glue hardening to meet the circuit board function.

[0037] At the same time Figure 5 As shown, the two side regions of the housing 1 are provided with bayonet 12, which is used to support and position the edge of the side circuit board 10 when installing the side circuit board 10. As a preferred embodiment, three or more bayonet 12 are provided in each side region to ensure that the support and positioning of the side circuit board 10 is firm and reliable. It can be understood that setting the bayonet 12 at the edge of the side circuit board 10 is conducive to reducing the interference with the arrangement of electronic components, so that the side circuit board 10 can arrange electronic components more fully, further improving the integration.

[0038] In this embodiment, a battery compartment is also provided in the central area of ​​the housing 1. The battery compartments are distributed on both sides of the central circuit board 11 to respectively arrange a rechargeable battery 13, such as a lithium battery. The battery 13 is also electrically connected to the central circuit board 11 or the side circuit board 10 to power the entire circuit board and electronic components. Among them, arranging the battery compartment in the central area is conducive to utilizing the thicker space in the central area to arrange a larger battery 13, thereby fully improving the capacity of the battery 13 and the endurance of the device.

[0039] It should be noted that in this embodiment, the battery compartment is separated from the side area and the position where the central circuit board 11 is located by a partition 14. For the separation of the side area, the partition 14 is a solid partition 14 protruding from the inner wall of the housing 1; for the separation of the position where the central circuit board 11 is located, the partition 14 utilizes the position of the inner wall of the housing 1 where the main groove 2 is located, so that the battery compartment can be exactly fitted to the central circuit board 11, so as to further improve the compactness of the interior of the housing 1. At the same time, it can also ensure the stability and reliability of the battery 13 and avoid contact between the battery 13 and the circuit board.

[0040] It should be noted that in this embodiment, the housing 1 itself is made of a relatively flexible material so that it can be bent to a certain extent, and the internal rigid-flexible board can maintain functional integrity when the housing 1 is bent. As a preferred embodiment, in this embodiment, the housing 1 is composed of an upper cover and a lower shell, and a connection structure that is convenient for disassembly, i.e., a quick-release structure, is provided between the upper cover and the lower shell, so that the housing 1 can be easily opened and the internal electronic components can be maintained and replaced.

[0041] In a specific implementation of this embodiment, the connection structure is a slot 15 and a top buckle 16 provided between the upper cover and the lower shell. When installing, the top buckle 16 is directly inserted into the slot 15 for quick installation and removal. Of course, in order to further improve the connection firmness, a small number of bolts can also be added for connection.

[0042] It is worth mentioning that for a hard-soft board or a flexible circuit board, the electronic component arrangement area thereon is used for the welding and placement of electronic components, and the soft board part can be flexibly bent. This area does not arrange electronic components, but is only used to arrange connecting wires, and the soft board part in the housing 1 will pass through the top of the battery compartment. The electronic component arrangement area can be potted by sealant, and has a three-proof effect after UV curing, and is in a hard state after curing, with high strength, which can prevent the three electronic component arrangement areas from bending, and provide good stability for the electronic components in this area. Therefore, this area does not need to be reinforced separately, thereby reducing the thickness occupied in the housing 1. Of course, in order to prevent the soft board part from colliding with the battery 13 multiple times, in this embodiment, a guide groove can be further provided on the inner surface of the upper cover, and the guide groove is located directly above the battery compartment. When the upper cover is installed, the soft board part is inserted into the guide groove (the cross section is L-shaped), so that it is also separated from the battery 13 to achieve the purpose of protecting the soft board part.

[0043] In summary, the ultra-thin multi-contact quick-detachable main housing provided in this embodiment can be made thin and light. The ultra-thin and short POGPIN connector 5 ensures that the thickness of the central position of the main housing will not increase too much, and the plug-in part is embedded in the groove by setting the groove, thereby minimizing the central thickness of the main housing. For example, when the present invention is applied to a smart eye mask, this design minimizes the probability of the head being compressed in a sleeping scene and maximizes comfort. In addition, through a reasonable internal layout, the thin side circuit boards 10 are arranged on both sides, and the relatively thick battery compartment is arranged in the center of the main housing, thereby maximizing the battery 13 capacity and battery life of the product, and reducing the thickness of the two ends of the main housing as much as possible, thereby improving comfort.

[0044] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
