In an implementation manner, referring to fig. 9, 10 and 11, a third through hole 212 is located in the middle of the display panel 21, the interference piece 211 is located near the third through hole 212, and the two interference pieces 211 are located on two sides of the third through hole 212, the opposite two ends of the display panel 21 are further provided with second mounting posts 213, the middle frame 11 is provided with fourth through holes 115, the control panel 22 is provided with fifth through holes 225, and second fasteners (not shown) are sequentially inserted through the fifth through holes 225 and the fourth through holes 115 to connect with the second mounting posts 213. For example, the second mounting post 213 may be internally threaded and the second fastener may be a screw. Thus, the fastening connection is performed at the end portions of both ends of the display panel 21 and the control panel 22, and the connection stability between the display panel 21 and the control panel 22 can be enhanced, so that the connection of the display panel 21 and the control panel 22 is more stable.

In one possible embodiment, as shown in fig. 9, the width W of the first reinforcing bead 114 is between 6-20mm, wherein the width W may be 6mm, 12mm, 18mm or 20 mm. When the width W is less than 6mm, it is inconvenient to provide the first through hole 112, and when the width W is greater than 20mm, the first reinforcing rib 114 easily presses the installation space of the second through hole 113, and the rotation shaft 222 does not easily pass through the second through hole 113.

Specifically, the first through hole 112 may be a circular hole, and the diameter of the first through hole 112 is between 4.5mm and 18mm, wherein the diameter of the first through hole 112 may be 4.5mm, 10mm, 15mm, or 18 mm.

It is understood that the first through hole 112 may also be an elliptical hole, a square hole, or the like, and when it is an elliptical hole or a square hole, the inner diameter of the first through hole 112 may be within the above range.

Specifically, the first mounting post 2111 may be a cylinder, and the diameter of the first mounting post 2111 is between 4-10mm, wherein the diameter of the first mounting post 2111 may be 4mm, 7mm, or 10 mm. The diameter of the first mounting post 2111 is within the above range, which facilitates the provision of internal threads on the first mounting post 2111, and ensures the assembly of the first mounting post 2111 with the first through hole 112. Further, the length of the first mounting post 2111 may be between 2.5-20mm, wherein the length may be 2.5mm, 10mm, 18mm, or 20 mm. It will be appreciated that the length of first mounting post 2111 is related to the mounting distance of control panel 22 and display panel 21, which refers to the distance between control panel 22 and display panel 21 when assembled.

Specifically, as shown in fig. 7, the height H of the spacing rib 2112 is between 0.2mm and 5mm, wherein the height H may be 0.2mm, 2mm, 4mm, or 5 mm. It will be appreciated that the sum of 2 times the height H of the retaining rib 2112 and the diameter of the first mounting post 2111 should be greater than the inner diameter of the first through hole 112, so as to ensure an interference fit connection between the interference member 211 and the first through hole 112.

In addition, the length L of the limiting rib 2112 is equal to the sum of the lengths of the guide section 2112a and the straight section 2112b, the length of the guide section 2112a can be between 0.5 and 10mm, and the length of the straight section 2112b can be between 6 and 15mm, wherein the length of the guide section 2112a can be 0.5mm, 5mm or 10mm, and the length of the straight section 2112b can be 6mm, 12mm or 15 mm. It will be appreciated that the length L of the retaining rib 2112 should be less than the length of the first mounting post 2111, so as to improve the stability of the assembly of the interference member 211 and the first through hole 112.

In one possible embodiment, the interference of the interference fit is in the range of 0.3-1.5mm, which may be 0.3mm, 0.5mm, 1mm or 1.5 mm. The interference is within the above range, so that the interference 211 and the first through hole 112 can be stably assembled on the one hand, and the interference is moderate on the other hand, thereby facilitating the assembly of the interference 211 and the first through hole 112.
