[0042] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear and understandable, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0043] Example 1

[0044] See also Figures 1 to 7 , is a highly sealed battery compartment as embodiment 1 of the present utility model. The battery compartment not only has high sealing but also has a convenient installation method, including a middle shell 10, wherein a placement position 11 for accommodating a battery block 20 is provided inside the middle shell 10; further comprising a battery cover 30 and a sealing ring 40, wherein the battery cover 30 is provided on the middle shell 10 and is used to restrict the battery block 20 to the placement position 11; the sealing ring 40 is provided between the battery cover 30 and the middle shell 10; a buckle 311 is provided on one side of the battery cover 30, and a slot 12 cooperating with the buckle 311 is provided on the middle shell 10, a hook 32 is further provided on the battery cover 30, and a first step 131 for the hook 32 to hook is provided on the middle shell 10. The highly sealed battery compartment of the present invention is provided with a battery cover 30 and a sealing ring 40 disposed between the middle shell 10 and the battery cover 30. At the same time, the buckle 311 cooperates with the slot 12, and the hook 32 cooperates with the first step 131. This not only allows the battery cover 30 to be quickly and securely installed on the middle shell 10, but also ensures sealing. Therefore, the back cover 80 does not need to be installed with screws. The back cover only serves as an external decoration, thereby maximizing the integrity of the back cover's appearance.

[0045] Please refer to the following for details: Figures 2 to 4 In this embodiment, the hook 32 is disposed on the end face of the battery cover 30 near the edge, and is positioned away from the latch 311. A protrusion 31 is provided on the sidewall of the battery cover 30, extending outward. The latch 311 is disposed at the edge of the protrusion 31. The protrusion 31 is arc-shaped, and the provision of the protrusion 31 facilitates the insertion of the latch 311 into the slot 12, avoiding interference during installation. The provision of the protrusion 31 facilitates the insertion of the latch 311 into the slot 12 more quickly. The middle shell 10 is provided with an avoidance hole 13 for the hook 32 to avoid during assembly. A first step 131 is provided on the inner sidewall of the avoidance hole 13 to facilitate the engagement of the latch 311 with the first step 131.

[0046] To further enhance the sealing performance of the sealing ring 40, the battery cover 30 is secured to the middle shell 10 with a plurality of screws 50. The battery cover 30 also features an annular surface 33 for contacting the sealing ring 40. A locking hole 34 is also provided on the battery cover 30, located outside the annular surface 33. The middle shell 10 also features an internally threaded hole 15 corresponding to the locking hole 34. The screw 50 passes through the locking hole 34 and is threadedly engaged with the internally threaded hole 15. Thus, a sealing ring 40 is positioned between the battery cover 30 and the middle shell 10. The battery cover 30 and the middle shell 10 are pre-assembled using the latch 311 and the slot 12, and the latch 311 and the first step 131, and then secured with the screws 50. This not only ensures a high level of waterproofing and reliability, but also facilitates fastening after pre-assembly. During installation, the battery cover 30 can be secured with the screws 50 without having to hold it down.

[0047] Please refer to the following for details: Figure 6 、 7 The sealing ring 40 is made of a soft, elastic material. The middle shell 10 also includes an annular groove 14 for the sealing ring 40 to fit into. The depth of the annular groove 14 is less than the thickness of the sealing ring 40. A groove is also provided on one end of the sealing ring 40 near the bottom of the groove 14, and a boss is provided on one side of the annular platform 33. The cooperation between the groove and boss further enhances the sealing performance. Therefore, when the battery cover 30 is assembled with the middle shell 10 and has an interference fit with the sealing ring 40, a continuous compressive force is generated between the battery cover 30, the sealing ring 40, and the middle shell 10, providing a waterproof function.

[0048] The outer edge of the sealing ring 40 is also provided with a plurality of limiting steps 41, and the middle shell 10 is also provided with a limiting groove 16 that cooperates with the limiting steps 41. The limiting groove 16 is connected to the annular groove 14, so that the sealing ring 40 is better restricted in the annular groove 14, preventing the sealing ring 40 from shifting due to the locking of the screw 50, so that the battery compartment has a higher sealing performance. For details, please refer to Figure 7 The sealing ring 40 is also provided with an annular portion so that the screw 50 can be locked on the middle shell 10 after passing through. At the same time, the annular portion cooperates with the limiting step 41 so that the sealing ring 40 can be better restricted in the annular groove 14.

[0049] Example 2

[0050] See also Figures 1 to 10, is a handheld terminal as embodiment 2 of the present invention, employing a highly sealed battery compartment structure. The handheld terminal also includes a core assembly 60, a front screen assembly 70, and a back cover 80. The core assembly 60 is disposed on the middle shell 10; the front screen assembly 70 is disposed on the middle shell 10, with the core assembly 60 positioned between the middle shell 10 and the front screen assembly 70; and the back cover 80 is disposed on the middle shell 10. The front screen assembly 70, core assembly 60, middle shell 10, and back cover 80 are disposed in sequence. The core assembly 60 and middle shell 10 are assembled to the front shell and screen assembly via screws. The front shell and screen assembly is provided with a waterproof ring, which provides a waterproof function when assembled with the middle shell 10.

[0051] In summary, the highly sealed battery compartment of the present invention is provided with a battery cover and a sealing ring disposed between the middle shell and the battery cover. At the same time, a snap fit is used with the slot and a hook fits with the first step. This not only allows the battery cover to be quickly and firmly installed on the middle shell, but also ensures sealing. Therefore, the back cover does not need to be installed with screws, and the back cover only serves as an external decoration, thereby maximizing the integrity of the aesthetic design appearance. The structure is simple, the manufacture is easy, the assembly process requirements are low, and it can be adapted to mass production. Furthermore, the battery cover that performs a sealing function is assembled by screw locking, and the back cover only serves as an external decoration. Therefore, the product can still maintain a high waterproof level after falling from a low position or being subjected to strong vibration.

[0052] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
