[0002] The main case is a shell structure used to protect circuit boards, such as mobile phone, watch, and radio cases. 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, light and thin. Especially for the fabric and electronics fusion scenario, the main case is often required to have a quick-detachable connection, because the fabric part of the product needs to be washed, while 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, the lightness or thinness of the main case has a significant impact on the user experience. Therefore, further improvement and optimization are needed.

[0009] Furthermore, the contact connector male socket includes a socket body, on which a second magnet and a gold-plated contact are provided. The second magnet is matched with the first magnet, and the gold-plated contact is matched with the POGPIN connector. The socket body is also provided with an anti-foolproof plug corresponding to the anti-foolproof groove.

[0010] Furthermore, the side circuit board adopts a double-sided electronic component arrangement, with one side arranging electronic components with a small thickness and the other side arranging electronic components with a 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 boards and the central circuit board are both rigid-flexible boards, and are connected to each other via a flexible board portion.

[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 provided, which is matched with an independent male contact connector and can be plugged in. The female contact connector is integrated with the shell 1, and includes a main groove 2 and an anti-foolproof 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 provided in the main groove 2, preferably a ring-shaped rubidium magnet with an anti-foolproof effect. Although this magnet is an annular one, 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 provided 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 the contact.

[0034] The male seat of the contact connector includes a seat body 6, on which a second magnet 7 is provided, and the aforementioned rubidium magnet with anti-foolproofing function is also preferably used. A gold-plated contact 8 is provided 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 contact connector is connected to the male 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 central area is thicker and the side areas are thinner. Two side circuit boards 10 are provided in the two side areas respectively. Preferably, the side circuit boards 10 adopt a double-sided electronic component arrangement, where one side is uniformly arranged with electronic components of smaller thickness, and the other side is uniformly arranged with electronic components of larger thickness, thereby reducing the thickness of the side circuit boards 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 various other 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 boards 10 and the central circuit board 11 in this embodiment are both rigid-flex boards, connected via the flexible portion of the rigid-flex boards. This allows them to flex to a certain degree with the housing 1. In other embodiments, the side circuit boards 10 and the central circuit board 11 can also be a single flexible printed circuit (FPC), with local reinforcement or adhesive curing ensuring secure mounting of electronic components and meeting the circuit board's functional requirements.

[0037] At the same time Figure 5 As shown, both side regions of the housing 1 are provided with latches 12, which are 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 latches 12 are provided in each side region to ensure that the support and positioning of the side circuit board 10 are firm and reliable. It can be understood that placing the latches 12 at the edge of the side circuit board 10 helps reduce interference with the layout of electronic components, thereby allowing the side circuit board 10 to more fully arrange electronic components, further improving the integration level.

[0038] In this embodiment, the central area of the housing 1 is also equipped with a battery compartment. The battery compartments are located on either side of the central circuit board 11, each housing 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 boards 10 to power the entire circuit board and electronic components. Placing the battery compartment in the central area facilitates utilizing the larger space in the central area to accommodate larger batteries 13, thereby significantly increasing the battery 13 capacity and the device's battery life.

[0039] It should be noted that in this embodiment, the battery compartment is separated from the side areas and the location of the central circuit board 11 by partitions 14. For the side areas, the partitions 14 are physical protrusions from the inner wall of the housing 1; for the location of the central circuit board 11, the partitions 14 utilize the location of the inner wall of the housing 1 where the main groove 2 is located. This allows the battery compartment to fit snugly within the central circuit board 11, further enhancing the compactness of the interior of the housing 1. This also ensures the stability and reliability of the battery 13, preventing 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 to allow for a certain degree of bending, etc., and the internal rigid-flex board can maintain its functional integrity when the housing 1 is bent. As a preferred embodiment, the housing 1 in this embodiment is composed of an upper cover and a lower shell. A connection structure that facilitates disassembly, namely a quick-release structure, is provided between the upper cover and the lower shell to enable easy opening of the housing 1 and maintenance and replacement of the internal electronic components.

[0041] In a specific embodiment of this embodiment, the connection structure is provided between the upper cover and the lower shell, and the top buckle 16 is provided. During installation, the top buckle 16 is directly inserted into the slot 15, which allows for quick installation and removal. Of course, to further enhance the connection strength, a small number of bolts can also be added for connection.

[0042] It is worth mentioning that for a rigid-flexible board or a flexible circuit board, the electronic component placement area thereon is used for the welding and placement of electronic components. The soft board portion can be flexibly bent. This area does not accommodate electronic components but is only used to arrange connecting wires. In addition, the soft board portion will pass through the top of the battery compartment in the housing 1. The electronic component placement area can be encapsulated with sealant, which has a three-proof effect after UV curing. After curing, it is in a hard state with high strength, which can prevent the three electronic component placement 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 portion 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. The guide groove is located directly above the battery compartment. When the upper cover is installed, the soft board portion is inserted into the guide groove (with an L-shaped cross section), thereby forming a certain separation from the battery 13, thereby achieving the purpose of protecting the soft board portion.

[0043] In summary, the ultra-thin, multi-contact, quick-detachable main housing provided by 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 does not increase too much, and the provision of a groove allows the plug-in portion to be embedded in 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 head compression during sleep 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 capacity and battery life of the product's battery 13, while minimizing the thickness of the two ends of the main housing, thereby improving comfort.

[0044] The technical features of the above embodiments can be combined arbitrarily. In order 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 merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present application shall be determined by the appended claims.
