[0026] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. Now, with reference to the accompanying drawings, the preferred embodiments of the present utility model will be described in detail.

[0027] An embodiment of the present utility model provides a mounting shell module, as Figure 1 . Figure 2 and Figure 4 shown, including a housing 10, a battery 20, a battery fixing bracket 30 and a power management circuit board 40. A mounting groove 101 is formed on the housing 10; the battery 20 is disposed in the mounting groove 101; the battery fixing bracket 30 is disposed on the battery 20, and first positioning posts 311 and second positioning posts 331 are respectively provided at opposite ends of the battery fixing bracket 30. The first positioning post 311 is connected to the housing 10 through a first fastener (not shown in the figure), and the second positioning post 331 is connected to the housing 10 through a second fastener (not shown in the figure); the power management circuit board 40 is disposed in the mounting groove 101 and is electrically connected to the battery 20. A third positioning post 410 is formed on a side of the power management circuit board 40 close to the bottom of the mounting groove 101. The third positioning post 410 is disposed on the bottom surface of the mounting groove 101, and the third positioning post 410 is connected to the housing 10 through a third fastener (not shown in the figure).

[0028] The mounting groove 101 formed on the outer shell 10 of the mounting shell module in this embodiment is used to provide a mounting environment for the battery 20 and the power management circuit board 40. By setting the battery fixing bracket 30, the battery 20 is fixedly connected to the outer shell 10. Specifically, the first positioning post 311 and the second positioning post 331 are respectively arranged at the opposite ends of the battery fixing bracket 30. The first positioning post 311 is connected to the outer shell 10 through the first fastener, and the second positioning post 331 is connected to the outer shell 10 through the second fastener, so as to fix the battery 20 on the outer shell 10 through the battery fixing bracket 30. And a third positioning post 410 is formed on one side of the power management circuit board 40 close to the bottom of the mounting groove 101. The third positioning post 410 is arranged on the bottom surface of the mounting groove 101 to support the power management circuit board 40. And the second positioning post 331 is connected to the outer shell 10 through the third fastener, so as to fix the power management circuit on the outer shell 10 through the third positioning post 410. The above settings of the battery fixing bracket 30 and the third positioning post 410 eliminate the positioning parts provided on the outer shell 10, making the bottom surface of the outer shell 10 a flat structure, which is convenient for demoulding when the outer shell 10 is produced by a mold. While ensuring the setting stability of the battery 20 and the power management circuit board 40 on the outer shell 10, the present utility model can also greatly improve the production efficiency of the outer shell 10.

[0029] Wherein, the electrical connection between the power management circuit board 40 and the battery fixing bracket 30 is used to provide power requirements for the display device.

[0030] As a preferred solution of this embodiment, as Figure 1 and 2 shown, the outer shell 10 includes a front shell 110 and a rear shell 120 that are buckled to each other. The above-mentioned mounting groove 101 is formed on the bottom of the rear shell 120. The front shell 110 and the mounting groove 101 enclose a closed mounting environment.

[0031] Wherein, a composition structure example of the outer shell 10 is given here. Specifically, the outer shell 10 includes a front shell 110 and a rear shell 120 that are buckled to each other. In the actual production process, the front shell 110 and the rear shell 120 are respectively produced by a mold, which improves the production efficiency of the outer shell 10. And the mounting cavity formed by the front shell 110 and the mounting groove 101 provides safe protection for the battery 20, the battery fixing bracket 30 and the power management circuit board 40, preventing damage to the battery 20, the battery fixing bracket 30 and the power management circuit board 40 caused by accidental situations such as impacts or knocks, and improving the service life of the mounting shell module. At the same time, the front shell 110 and the rear shell 120 that are buckled to each other are also convenient for the assembly of the mounting shell module. Specifically, in the actual installation process, first, prepare the rear shell 120, place the battery 20, the battery fixing bracket 30 and the power management circuit board 40 in the mounting groove 101. After the above devices are installed, buckle the front shell 110 on the rear shell 120 to complete the assembly of the mounting shell module.

[0032] As a preferred solution of this embodiment, as Figures 2 to 4 shown, the display device further includes: a button circuit board 50, disposed in the installation groove 101 and electrically connected to the power management circuit board 40. A positioning hole 501 is formed on the button circuit board 50, and a fourth positioning post 1121 is formed on the front shell 110. The fourth positioning post 1121 can be inserted into the positioning hole 501 to fix the button circuit board 50.

[0033] Among them, in the operation of the display device to achieve interaction with the user, a button circuit board 50 also needs to be electrically connected to the power management circuit board 40 in its power facilities to control the power on or off of the display device. The button circuit board 50 is disposed in the installation groove 101, and a positioning hole 501 is formed on the button circuit board 50. By inserting the fourth positioning post 1121 formed on the front shell 110 into the positioning hole 501, the button circuit board 50 is connected to the front shell 110, and the button circuit board 50 is fixed on the outer shell 10. Since the installation groove 101 is not formed on the front shell 110 and its structure is relatively simple, even if the fourth positioning post 1121 is provided on the front shell 110, when the front shell 110 is produced using a mold according to its structure, the front shell 110 will not have the phenomenon of difficult demolding. Therefore, the above structure not only realizes the stable setting of the button circuit board 50 on the outer shell 10, but also does not reduce the production efficiency of the outer shell 10.

[0034] As a preferred solution of this embodiment, referring to Figure 4 , the battery fixing bracket 30 includes a first fixing portion 310, a second fixing portion 320, and a third fixing portion 330 that are sequentially connected.

[0037] Among them, an example of the connection between the first positioning post 311, the second positioning post 331, the third positioning post 410, and the fourth positioning post 1121 and the rear case 120 is given here. Specifically, a first threaded hole 31101 is formed along the height direction of the first positioning post 311. At the same time, a first mounting hole 1201 is formed at the bottom of the mounting groove 101. The first fastener can pass through the first mounting hole 1201 and then be threadedly connected to the first threaded hole 31101 to achieve the purpose of firmly connecting the first positioning post 311 to the housing 10 through the first fastener. A second threaded hole 33101 is formed along the height direction of the second positioning post 331. At the same time, a second mounting hole 1202 is formed at the bottom of the mounting groove 101. The second fastener can pass through the second mounting hole 1202 and then be threadedly connected to the second threaded hole 33101 to achieve the purpose of firmly connecting the second positioning post 331 to the housing 10 through the second fastener.
