[0002] With the increasing prevalence of electronic devices in daily life, their design requirements are also rising, especially in complex environments such as humidity and dust, where sealing performance becomes paramount. In terms of sealing technology, electronic devices typically rely on precise sealing structures on their casings to ensure performance. However, when maintenance of internal electronic components, such as replacing critical parts like batteries, is required, the entire casing must be disassembled. This not only increases the difficulty of maintenance but also makes the maintenance process extremely cumbersome. Therefore, improving the maintainability of electronic devices while maintaining their sealed casing design has become a pressing issue in the design field. Utility Model Content

[0003] The main objective of this invention is to provide a waterproof housing and electronic device, which aims to improve the maintainability of the electronic device while maintaining the sealed design of the housing.

[0004] To achieve the above objectives, the outer shell structure proposed in this utility model includes a lower shell and an upper cover. The upper cover includes a fixed part and a movable part that are flexibly connected to each other. The fixed part is sealed to the lower shell and forms a cavity for accommodating electronic devices and having an opening. The movable part seals and covers the opening and can expose the opening when it moves relative to the fixed part.

[0005] This invention also proposes an electronic device that includes the housing structure described in the above embodiments. Attached Figure Description

[0028] This utility model proposes a shell structure 100.

[0029] Please see Figure 1 and Figure 9 In one embodiment of the present invention, the outer shell structure 100 includes a lower shell 1 and an upper cover 2. The upper cover 2 includes a fixed part 21 and a movable part 22 that are flexibly connected to each other. The fixed part 21 is sealed to the lower shell 1 and forms a cavity 1a for accommodating electronic devices and having an opening 1a1. The movable part 22 seals and covers the opening 1a1 and can expose the opening 1a1 when it moves relative to the fixed part 21.

[0030] In this embodiment, the upper cover 2 includes a fixed part 21 and a movable part 22 that are flexibly connected to each other. Both the fixed part 21 and the movable part 22 adopt a cover plate structure to close the lower shell 1. The fixed part 21 is connected to the movable part 22 through a flexible connector 24. The flexible connector 24 can deform so that the movable part 22 can rotate or twist relative to the fixed part 21 to close or open the lower shell 1. It should be noted that the fixed part 21 and the movable part 22 can also be formed on the same cover plate. In this case, the cover plate is made of a material with a certain elastic deformation capability. A folding seam is provided on the cover plate to divide the cover plate into the fixed part 21 and the movable part 22. The bottom wall of the folding seam connects the fixed part 21 and the movable part 22. The presence of the folding seam weakens the thickness of the cover plate, so that the bottom wall of the folding seam can deform to a certain extent, allowing the movable part 22 to rotate relative to the fixed part 21 to close or open the lower shell 1. It is understandable that, in addition to a plate-like structure, the top cover 2 can also adopt a block-like structure or an irregular structure, etc., and can be designed according to the actual needs of electronic devices. This application does not limit it in this regard.

[0031] The fixing part 21 is sealed to the lower shell 1, forming a cavity 1a with an opening 1a1 for accommodating electronic devices. The cavity 1a, corresponding to the opening 1a1, is used to house removable electronic devices such as the battery 200. The cavity 1a also contains a PCB and a flexible circuit 400. One end of the flexible circuit 400 is connected to the PCB board 300, and the other end is connected to a contact connector or a plug-in connector. The flexible circuit 400 can adapt to various complex structural shapes within the cavity 1a. The battery 200 has a corresponding contact connector or plug-in connector, which is compatible with the connector on the flexible circuit 400 to supply power to the PCB board 300. The contact connector or plug-in connector allows for quick connection or disconnection between the battery 200 and the circuit board. The movable part 22 is detachably connected to the lower shell 1 body via screws or snap-fit ​​structures, so there is no need to disassemble the entire shell. Simply detach the movable part 22 from the lower shell 1 body to allow the battery 200 to be taken out through the cavity 1a1 or placed into the cavity 1a. After taking it out and placing it into the cavity 1a, the movable part 22 is closed to seal the cavity 1a, which can quickly restore the sealing performance of the shell structure 100. In this way, the maintainability of the electronic device is improved while maintaining the sealed design of the electronic device shell.

[0032] After the outer shell structure 100 is assembled, the fixing part 21 maintains a sealed connection with the lower shell 1. It should be noted that the fixing part 21 can achieve a sealed connection with the shell through a sealing element (such as an elastic soft rubber material), wax sealing, or by making the fixing part 21 and the outer shell structure 100 an integrally formed structure. The movable part 22 can be designed with a sealing connection method according to the sealing requirements. For example, the movable part 22 can be set to an interference fit with the shell, or a sealing element can be provided on the movable part 22 to meet higher sealing requirements. When the fixing part 21 or the movable part 22 is sealed to the shell through a sealing element, the fixing part 21 or the movable part 22 can be fixed to the shell through a structure such as screws or clips.

[0033] In this embodiment, the housing structure 100 flexibly connects the fixed part 21 and the movable part 22. The fixed part 21 is sealed to the lower shell 1 and forms a cavity 1a for accommodating electronic devices, having an opening 1a1. The movable part 22 seals and covers the opening 1a1, but can expose the opening 1a1 when it moves relative to the fixed part 21. Without disassembling the entire housing, the battery 200 can be removed or placed into the cavity 1a simply by opening the movable part 22. After removal and placement into the cavity 1a, closing the movable part 22 seals the cavity 1a, quickly restoring the airtightness of the housing structure 100 and facilitating maintenance of the electronic devices within it. Thus, while maintaining the airtight design of the electronic device's housing, the maintainability of the electronic device is improved.

[0034] Further, please refer to Figures 1 to 3 In one embodiment of the present invention, the outer shell structure 100 further includes a first sealing member 23, the first sealing member 23 having a first sealing section 231 and a second sealing section 232 connected to each other; the first sealing section 231 is disposed along the periphery of the fixed part 21 and elastically abuts against the lower shell 1, the second sealing section 232 is disposed along the periphery of the movable part 22, and when the movable part 22 seals and covers the cavity opening 1a1, the second sealing section 232 elastically abuts against the lower shell 1.

[0035] In this embodiment, the fixing part 21 and the movable part 22 are plate-shaped structures. Therefore, the upper cover 2, which is flexibly connected by the fixing part 21 and the movable part 22, is a plate-shaped structure as a whole. The first sealing member 23 extends along the periphery of the upper cover 2 and can be made of soft rubber or silicone. The upper cover 2 can be located on the top of the lower shell 1. At this time, the bottom wall of the upper cover 2 is connected to the top wall of the lower shell 1. The first sealing member 23 can be located on the bottom wall of the upper cover 2. When the upper cover 2 and the lower shell 1 are connected and fixed by screws or the like, the bottom wall of the upper cover 2 and the top wall of the lower shell 1 press the first sealing member 23 together, and the first sealing member 23 undergoes elastic deformation to ensure the sealing between the upper cover 2 and the lower shell 1. The upper cover 2 can also be located inside the lower shell 1. In this case, the side wall of the upper cover 2 is connected to the inner side wall of the lower shell 1. The first sealing element 23 can be located on the side wall of the upper cover 2. When the upper cover 2 is installed into the lower shell 1, the side wall of the upper cover 2 and the inner side wall of the lower shell 1 press the first sealing element 23 together. The first sealing element 23 undergoes elastic deformation to achieve a seal between the upper cover 2 and the lower shell 1. This arrangement allows the first sealing element 23 to be evenly compressed and is not affected by the density of screws, etc., thus avoiding uneven deformation of the first sealing element 23 due to uneven force, which could cause gaps and ensure the sealing performance between the upper cover 2 and the lower shell 1.

[0036] Since the movable part 22 can be bent and rotated relative to the fixed part 21, the first sealing member 23 corresponds to the fixed part 21 and the movable part 22, forming a first sealing section 231 and a second sealing section 232 that are connected to each other. The first sealing section 231 is arranged along the periphery of the fixed part 21 and is fixedly connected to the fixed part 21. After the outer shell structure 100 is assembled, the fixed part 21 is fixedly connected to the lower shell 1, so the first sealing section 231 and the lower shell 1 maintain elastic contact. The second sealing section 232 is arranged along the periphery of the movable part 22 and is fixedly connected to the movable part 22. The second sealing section 232 moves closer to or away from the lower shell 1 with the movable part 22. When the movable part 22 seals and covers the cavity opening 1a1, the movable part 22 drives the second sealing section 232 closer to the lower shell 1 to maintain the second sealing section 232 and the lower shell 1 in elastic contact. The movable part 22 and the lower shell 1 are detachably connected by screws or snap-fit ​​structures to strengthen the connection strength between the movable part 22 and the lower shell 1 to meet the strength requirements of the outer shell. The first sealing section 231 can be connected to the fixed part 21 by means of bonding or welding. Similarly, the second sealing section 232 can be connected to the movable part 22 by means of bonding or welding.

[0037] Further, please refer to Figure 1 , Figure 2 , Figure 7 and Figure 9 In one embodiment of the present invention, the upper cover 2 further includes a flexible connector 24, which connects the fixed part 21 and the movable part 22.

[0038] In this embodiment, the flexible connector 24 can be made of soft materials such as rubber or silicone, while the fixed part 21 and the movable part 22 can be made of hard plastic materials such as PC or ABS. The flexible connector 24 is connected to the fixed part 21 and the movable part 22 by means of bonding or welding. The flexible connector 24 can deform to allow the movable part 22 to move relative to the fixed part 21, and it can also achieve a seal between the fixed part 21 and the movable part 22. By increasing the size of the flexible connector 24, the range of motion and amplitude of the movable part 22 can be increased, thereby improving the flexibility of the movable part 22 and further enhancing the maintainability of the electronic device while maintaining the sealed design of the electronic device's casing.

[0039] Further, please refer to Figure 1 , Figure 2 , Figure 7 and Figure 9 In one embodiment of the present invention, the flexible connector 24 extends toward the first sealing member 23 and is fixedly connected to the first sealing member 23.

[0040] In this embodiment, in order to simplify the production process, the flexible connector 24 extends toward the first seal 23 and is fixedly connected to the first seal 23. The flexible connector 24 and the first seal 23 can be manufactured using an integral molding process. Furthermore, the first seal 23, the flexible connector 24, the fixed part 21, and the movable part 22 can be connected by bonding or welding in one step, without the need for multiple bonding or welding steps, thus simplifying the production process.

[0041] Further, please refer to Figure 1 , Figure 3 and Figure 7 In one embodiment of the present invention, a connecting structure 11 is provided in the cavity 1a; the connecting structure 11 abuts against the fixed part 21; and / or, the connecting structure 11 abuts against the movable part 22.

[0042] In this embodiment, one end of the connecting structure 11 is connected to the side wall or bottom wall of the cavity 1a, and the other end of the connecting structure 11 abuts against the bottom wall of the fixed part 21 or the movable part 22, thereby supporting the fixed part 21 or the movable part 22. The connecting structure 11 can resist the external force applied to the fixed part 21 or the movable part 22 to meet the working scenarios of various external forces on the electronic device and improve the practicality of the electronic device.

[0043] Further, please refer to Figure 1 , Figure 3 and Figure 7In one embodiment of the present invention, the outer shell structure 100 further includes a fastening screw 3; the fixing part 21 is provided with a through hole 2a, and the connecting structure 11 is provided with a mounting hole 11a on the side facing the fixing part 21; and / or, the movable part 22 is provided with a through hole 2a, and the connecting structure 11 is provided with a mounting hole 11a on the side facing the movable part 22; the fastening screw 3 passes through the through hole 2a and is screwed to the inner wall of the mounting hole 11a.

[0044] In this embodiment, to connect the fixed part 21, the movable part 22, and the lower shell 1, a connector is provided inside the cavity, and a mounting hole 11a is provided on the connector. A corresponding through hole 2a is provided on the fixed part 21 or the movable part 22. The connection between the fixed part 21, the movable part 22, and the lower shell 1 is achieved by passing a fastening screw 3 through the through hole 2a and screwing it to the inner wall of the mounting hole 11a. When it is necessary to remove electronic components such as the battery 200, the screw on the movable part 22 is loosened, allowing the movable part 22 to move away from the lower shell 1 so that the cavity opening 1a1 is exposed, and the electronic components can be removed from the cavity opening 1a1.

[0045] Further, please refer to Figure 2 and Figure 5 In one embodiment of this utility model, a second sealing element 25 is provided around the through hole 2a.

[0046] In this embodiment, in order to ensure the sealing performance at the through hole 2a, a second sealing element 25 is provided on the periphery of the through hole 2a facing the cavity 1a. The second sealing element 25 can be made of soft rubber or silicone. The second sealing element 25 can be adapted to the shape of the through hole 2a. For example, a circular through hole corresponding to the through hole 2a can be provided on the second sealing element 25, and the through hole can be slightly smaller than the through hole 2a, so that the second sealing element 25 is in close contact with the outer wall of the fastening screw 3, thus ensuring the sealing performance of the second sealing element 25.

[0047] Further, please refer to Figure 2 and Figure 5 In one embodiment of the present invention, the second sealing member 25 extends toward the first sealing member 23 and is fixedly connected to the first sealing member 23.

[0048] In this embodiment, to simplify the production process, the second seal 25 extends toward the first seal 23 and is fixedly connected to the first seal 23. The second seal 25 and the first seal 23 can be manufactured using an integral molding process. Furthermore, the first seal 23, the second seal 25, the flexible connector 24, the fixing part 21, and the moving part 22 can be connected by bonding or welding in one step, eliminating the need for multiple bonding or welding steps. This simplifies the production process and facilitates the alignment of the second seal 25 with the through hole 2a.

[0049] Further, please refer to Figures 4 to 8In one embodiment of the present invention, the first sealing member 23 is provided with a protruding rib 233, which extends along the periphery of the first sealing section 231 and the second sealing section 232 and elastically abuts against the side wall of the cavity 1a1.

[0050] In this embodiment, one or more layers of protruding ribs 233 are provided on the outer peripheral wall of the first sealing member 23, that is, one or more layers of protruding ribs 233 are provided on the first sealing section 231 and the second sealing section 232. The purpose is to reduce the contact area between the first sealing member 23 and the lower shell 1, increase the pressure generated when the first sealing member 23 abuts against the lower shell 1, and make the first sealing member 23 fit more tightly against the side wall of the cavity 1a1, thereby improving the sealing performance of the first sealing member 23. Since the material of the contact surface between the protruding ribs 233 and the lower shell 1 is not completely rigid, the greater pressure will cause slight deformation of the contact surface, which will increase the actual coefficient of friction, thereby indirectly increasing the frictional force. The frictional force makes the external force required to separate the first sealing member 23 from the lower shell 1 greater, which is more conducive to maintaining the sealing state.

[0051] This utility model also proposes an electronic device.
