The predetermined track may extend along the height direction (x-axis direction in fig. 1) of the rear housing assembly, that is, the predetermined track is a straight line, so that the positioning pin 30 is quickly inserted into the first hook 110 and the second hook 210 through the bottom of the rear housing 20, so that the fixing arm 310 of the positioning pin 30 is connected with the bottom of the rear housing 20 through the second screw 330, and the purpose of having no exposed screw in the front view portion of the back of the rear housing assembly is achieved. Of course, the predetermined trajectory may be an arc as long as it is ensured that the positioning pin 30 can simultaneously pass through the target first hook 110 and the target second hook 210, which is not limited by the disclosure.

Specifically, the first hooks 110 and the second hooks 210 located on the same positioning pin 30 are alternately arranged in the extending direction of the positioning pin 30. As shown in fig. 5 and 6, in the height direction of the rear housing assembly, the first hooks 110 and the second hooks 210 located on the same side are alternately arranged, that is, the first hooks 110 and the second hooks 210 located on the same positioning pin 30 are alternately arranged, so that the stability of the connection between the rear housing 20 and the back panel 10 can be further improved. Of course, the first hooks 110 and the second hooks 210 located on the same positioning pin 30 may be alternatively arranged by a group of the first hooks 110 and a group of the second hooks 210.

For example, as shown in fig. 5, three first hooks 110 and three second hooks 210 are respectively disposed on the same positioning pin 30. Of course, the first hooks 110 and the second hooks 210 located on the same positioning pin 30 may also be respectively provided with one, two, four or more, and the number of the first hooks 110 and the number of the second hooks 210 may also be the same or different, which is not limited in this disclosure.
