[0059] See also Figure 6 The support plate 30 is provided with a grounding surface 34 on one side of the surface in the thickness direction for grounding. For example, the grounding surface 34 is electrically connected to the housing assembly 10, so that the housing assembly 10 or the grounding surface 34 is grounded. For example, the grounding surface 34 is electrically connected to the flexible display screen 20, so that the flexible display screen 20 or the grounding surface 34 is grounded.

[0060] In one embodiment, the ground plane 34 may include a first ground plane 341 disposed on the first bearing portion 31 and a second ground plane 342 disposed on the second bearing portion 32.

In some scenarios, the grounding member 312 can be directly connected to the flexible display screen 20. In some scenarios, the carbon fiber layer 311 can be connected to the housing assembly 10, such as the first housing 11.

[0071] See also Fig. 9 , Fig. 9 for Figure 8A schematic diagram of the structure of the support plate 30 in another embodiment of the embodiment shown. The carbon fiber layer 311 and the grounding member 312 are stacked, and since the grounding member 312 is relatively small, the carbon fiber layer 311 can be filled to the position between the grounding member 312 and the carbon fiber bearing portion 33, so that a part of the surface of the first bearing portion 31 on one side is the grounding surface, and the surface of the carbon fiber layer 311 is flush with the surface of the carbon fiber bearing portion 33.

[0072] See also Figure 8 , Figure 8 for Figure 2 The second bearing portion 32 may include a carbon fiber layer 321 and a grounding member 322 stacked in the thickness direction of the support plate 30. The grounding surface 34, such as the second grounding surface 342, is disposed on the grounding member 322.

[0073] The carbon fiber layer 321 and the grounding member 322 may be connected in the same manner as the bonding method between the grounding member and the carbon fiber bearing portion 33 in the above embodiment.

[0074] In some embodiments, the grounding member 322 is located on the side of the carbon fiber layer 321 close to the flexible display screen 20, so as to facilitate the static electricity flow on the flexible display screen 20, protect the flexible display screen 20, and of course, meet the radio frequency requirements of the antenna. In some scenarios, the grounding member 322 can be directly connected to the flexible display screen 20. In some scenarios, the carbon fiber layer 321 can be connected to the housing assembly 10, such as the second housing 12.

[0075] Of course, the grounding member 322 may also be located on a side of the carbon fiber layer 321 close to the housing assembly 10, such as the second housing 12. In some scenarios, the grounding member 322 may be directly connected to the housing assembly 10, such as the second housing 12. In some scenarios, the carbon fiber layer 321 may be connected to the flexible display screen 20.

[0076] In some embodiments, the carbon fiber layer 321 and the carbon fiber bearing portion 33 may be an integral structure.

[0077] See also Figure 8 The carbon fiber layer 321 and the grounding member 322 are stacked, and the entire surface of the grounding member 322 away from the carbon fiber layer 321 is the surface of the support plate 30 on one side and serves as the second grounding surface 342.

[0078] See also Fig. 9The carbon fiber layer 321 and the grounding piece 322 are stacked. Since the grounding piece 322 is relatively small, the carbon fiber layer 321 can be filled to the position between the grounding piece 322 and the carbon fiber bearing portion 33, so that part of the surface of the second bearing portion 32 on one side is the grounding surface, and the surface of the carbon fiber layer 321 is flush with the surface of the carbon fiber bearing portion 33.

It can be understood that the step surface 313 and the step surface 331 can increase the contact area between the first bearing part 31 and the carbon fiber bearing part 33, and then the connection strength between the first bearing part 31 and the carbon fiber bearing part 33 can be enhanced. Of course, the end surface where the first bearing part 31 and the carbon fiber bearing part 33 are connected to each other is not limited to a step surface, but can also be an inclined surface.

It can be understood that the step surface 323 and the step surface 332 can increase the contact area between the second bearing part 32 and the carbon fiber bearing part 33, and then the connection strength between the second bearing part 32 and the carbon fiber bearing part 33 can be enhanced. Of course, the end surface where the second bearing part 32 and the carbon fiber bearing part 33 are connected to each other is not limited to the step surface, but can also be an inclined surface.

It can be understood that the groove 314 and the protrusion 333 can increase the contact area between the first bearing part 31 and the carbon fiber bearing part 33, and then the connection strength between the first bearing part 31 and the carbon fiber bearing part 33 can be enhanced. Of course, the matching relationship between the first bearing part 31 and the carbon fiber bearing part 33 is not limited to the matching relationship between the groove 314 and the protrusion 333. In some embodiments, the positions of the groove 314 and the protrusion 333 can be interchanged.
