[0023] To facilitate the understanding of this application, the following provides a more detailed description of this application in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is stated as "fixed to" another element, it can be directly on the other element, or there can be one or more intermediate elements therebetween. When an element is stated as "connected to" another element, it can be directly connected to the other element, or there can be one or more intermediate elements therebetween.

[0025] In addition, the technical features involved in different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0026] Display devices usually come in multiple sizes according to usage requirements. Therefore, during the assembly process, it is necessary to assemble housing structures of different sizes to adapt to display panels of different sizes, ultimately forming display devices of different sizes. Thus, when assembling the rear cover, especially the small rear cover at the bottom of the display device, the small rear cover is currently usually divided into three independent parts: left, middle, and right. The left and right parts are common parts. When assembling display devices of different sizes, only intermediate parts of different lengths need to be selected. However, such a structure makes the installation rather troublesome. It is necessary to first install the three parts of left, middle, and right into one body and then install it onto the border component, or install the three parts of left, middle, and right onto the border component in sequence.

[0027] In this application, an integral rear housing 30 formed by a thermoforming process is used to replace the independent left, middle, and right three-part structure, thereby reducing the number of rear housings 30, effectively reducing the installation difficulty. In addition, corresponding strengthening structures are provided on the rear housing 30 to increase the overall strength of the rear housing 30, reduce the deformation of the rear housing 30. In addition, the length of the connecting member 40 connecting the rear housing 30 and the frame assembly 10 is extended, so that the connecting member 40 can be connected to the rear housing 30 at at least two places, further improving the stability of the connection between the rear housing 30 and the frame assembly 10.

[0028] Please refer to Figure 1 and Figure 2 , this application provides a housing structure 100 for an interactive flat panel. The housing structure 100 includes a frame assembly 10, a back plate 20, a rear housing 30, and a connecting member 40. The back plate 20 and the rear housing 30 are both connected to the same side of the frame assembly 10, and the rear housing 30 is connected to the back plate 20. The connecting member 40 is respectively connected to the rear housing 30 and the frame assembly 10 to fix the rear housing 30 on the frame assembly 10. The rear housing 30 includes a left rear housing part 31, a middle rear housing part 32, and a right rear housing part 33. The left rear housing part 31 and the right rear housing part 33 are respectively connected to both ends of the middle rear housing part 32, and the left rear housing part 31, the middle rear housing part 32, and the right rear housing part 33 are integrally formed. Through the above structure, the integrally formed rear housing 30 can be directly installed on the frame assembly 10, reducing the number of parts of the rear housing 30, reducing the installation difficulty, and improving the assembly efficiency.

[0029] In some embodiments, the rear housing is made of one of polypropylene, polyethylene terephthalate, polycarbonate, polystyrene, and polyvinyl chloride by a thermoforming process. Compared with the conventional plastic housings in the prior art, the use of the above materials for the rear housing in this application is beneficial for integral forming manufacturing by the thermoforming process. The above materials also have the advantages of good fire resistance, good plasticity, light weight, high toughness, and good strength.

[0030] In some embodiments, please refer to Figure 3, the middle and rear housing part 32 includes a first plate body 321 and a second plate body 322. The first plate body 321 and the second plate body 322 are connected so that the cross-sections of the first plate body 321 and the second plate body 322 are substantially in an L-shaped structure. Specifically, the first plate body 321 is respectively connected to the back plate 20 and the second plate body 322, and the second plate body 322 is respectively connected to the first plate body 321 and the frame assembly 10. Moreover, both the first plate body 321 and the second plate body 322 are detachably and fixedly connected to the connecting member 40. In this way, the first plate body 321 and the second plate body 322 can be connected to the back plate 20 to facilitate jointly enclosing the space surrounded by the frame assembly 10, and at the same time, it can also enhance the stability of the connection between the first plate body 321 and the second plate body 322 and the frame assembly 10. Wherein, the included angle R1 between the plane where the first plate body 321 is located and the plane where the second plate body 322 is located is 87°≤R1≤93°, that is, the first plate body 321 and the second plate body 322 are substantially vertically connected. The rear housing 30 is assembled at the bottom of the housing structure 100. Components such as buttons can be installed on the rear housing 30. Therefore, setting the second plate body 322 to be substantially vertically connected to the first plate body 321 can, on the one hand, increase the bottom space of the housing structure 100, and on the other hand, keep the bottom of the housing structure 100 flat, improving the aesthetics. When components such as buttons are installed, the flat second plate body 322 is also helpful for improving the operation convenience.

[0031] In some embodiments, please refer to Figure 3 , the left rear housing part 31 includes a third plate body 311.

The included angle between the third plate body 311 and the first plate body 321 on the side close to the frame assembly 10 is an obtuse angle. The third plate body 311 is connected to the second plate body 322, that is, the included angle R2 between the plane where the third plate body 311 is located and the plane where the second plate body 322 is located satisfies: 87°≤R2≤93°. A first inclined portion 21 is provided in the region of the back plate 20 close to its side edge, and the third plate body 311 is attached and connected to the first inclined portion 21. By providing the first inclined portion 21 on the back plate 20 and the structure in which the third plate body 311 is attached and connected to the first inclined portion 21, the space occupied by the side portion of the housing structure 100 can be reduced, and it is also convenient for the carrier to hold the side portion of the housing structure 100 when carrying the housing structure 100.

[0032] In some embodiments, please refer to Figure 3, the left rear housing part 31 further includes a fifth plate body 312. The fifth plate body 312 and the first plate body 321 are respectively connected to both ends of the third plate body 311. The plane where the fifth plate body 312 is located is substantially parallel to the plane where the first plate body 321 is located. The fifth plate body 312 is fixedly connected to the frame assembly 10 or the back plate 20. Since the third plate body 311 extends in an inclined state, by connecting the fifth plate body 312 to the frame assembly 10 or the back plate 20, the third plate body 311 can be fixed to the frame assembly 10, reducing the difficulty of fixed installation and enhancing the stability of the connection between the third plate body 311 and the frame assembly 10.

The fourth plate body 331 is connected to the second plate body 322, that is, the included angle R3 between the plane where the fourth plate body 331 is located and the plane where the second plate body 322 is located satisfies: 87° ≤ R3 ≤ 93°. A second inclined part 22 is provided in the area of the back plate 20 close to its other side edge. The fourth plate body 331 is in close fit connection with the second inclined part 22. By providing the second inclined part 22 on the back plate 20 and the structure in which the fourth plate body 331 is in close fit connection with the second inclined part 22, the space occupied by the side part of the housing structure 100 can be reduced, and it is also convenient for the handler to hold the side part of the housing structure 100 when carrying the housing structure 100.

The plane where the sixth plate body 332 is located is substantially parallel to the plane where the first plate body 321 is located. The sixth plate body 332 is fixedly connected to the frame assembly 10 or the back plate 20. Since the fourth plate body 331 extends in an inclined state, by connecting the sixth plate body 332 to the frame assembly 10 or the back plate 20, the fourth plate body 331 can be fixed to the frame assembly 10, reducing the difficulty of fixed installation and enhancing the stability of the connection between the fourth plate body 331 and the frame assembly 10.
