Detailed implementation manners

[0029] To make the objects, features, and advantages of this patent more obvious and understandable, the technical solutions in the embodiments of this patent will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this patent. Obviously, the described embodiments are only a part of the embodiments of this patent, rather than all the embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of this patent.

[0030] Combined with Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the circuit board mounting structure provided by the embodiment of the present patent includes a keyboard end housing 1, a display end housing 2, a flexible circuit board 3, and a support assembly; the display end housing 2 is rotatably connected to the keyboard end housing 1; one end of the flexible circuit board 3 is connected to the keyboard end housing 1, and the other end of the support assembly is connected to the display end housing 2; the support assembly includes a first support member 4, the first support member 4 is connected to the keyboard end housing 1, and a receiving groove 11 is formed between the first support member 4 and the keyboard end housing 1. The flexible circuit board 3 is received in the receiving groove 11 after forming a first winding portion 31 through the first support member 4. In the embodiment of the present disclosure, the first support member 4 can play a role of support and guidance. The flexible circuit board 3 is wound around the first support member 4 and then received in the receiving groove 11, so that the flexible circuit board 3 can be received in the receiving groove 11 when the swing mechanism is in the unfolded state, the folded state, and the process of switching between the unfolded state and the folded state, making it difficult to see the redundant flexible circuit board 3 on the appearance of the electronic device and making the appearance more beautiful.

[0031] In some specific embodiments, the support assembly includes a second support member 5. The first support member 4 and the second support member 5 are arranged up and down. The first support member 4 is connected to the second support member 5, and a channel is formed between the first support member 4 and the second support member 5. The flexible circuit board 3 passes through the channel and is wound around the second support member 5 to form a second winding portion 32, so that the shape of the flexible circuit board 3 is fixed or maintains a preset shape or preset position, and the flexible circuit board 3 can be received in the receiving groove 11 when the swing mechanism is in the unfolded state, the folded state, and the process of switching between the unfolded state and the folded state, making it difficult to see the redundant flexible circuit board 3 on the appearance of the electronic device and making the appearance more beautiful.

[0032] Optionally, both the first support member 4 and the second support member 5 are plate-shaped. The first support member 4 and the second support member 5 are stacked and clamp the flexible circuit board 3, which can reduce the possibility of irregular deformation or pulling of the flexible circuit board 3 and realize the control of the bending form of the flexible circuit board 3.

[0033] In some specific embodiments, the first support member 4 and the second support member 5 clamp the flexible circuit board 3 to fix the flexible circuit board 3 at the support assembly, which can reduce the possibility of irregular deformation or pulling of the flexible circuit board 3, realize the control of the bending form of the flexible circuit board 3, and make the flexible circuit board 3 maintain a preset shape or preset position. Thus, the flexible circuit board 3 can be received in the receiving groove 11 when the swing mechanism is in the unfolded state, the folded state, and the process of switching between the unfolded state and the folded state, making it difficult to see the redundant flexible circuit board 3 on the appearance of the electronic device and making the appearance more beautiful.

[0034] In some specific embodiments, the flexible circuit board 3 is in an S shape in the area of the support assembly. By bending the flexible circuit board 3 to form an arc shape, the possibility of the flexible circuit board 3 being folded in half is avoided, which can reduce the possibility of irregular deformation or pulling of the flexible circuit board 3 and realize the control of the bending shape of the flexible circuit board 3.

[0035] In some specific embodiments, one of the first support member 4 and the second support member 5 is provided with a clamping portion 42, and the other of the first support member 4 and the second support member 5 is provided with a clamping portion 52. The clamping portion 42 and the clamping portion 52 are in clamping cooperation, which facilitates the disassembly and installation of the first support member 4 and the second support member 5.

[0036] Optionally, one of the clamping portion 42 and the clamping portion 52 can be a clamping groove, and the other can be a clamping block, which facilitates the disassembly and installation of the first support member 4 and the second support member 5.

[0037] Optionally, the clamping portion 42 and the clamping portion 52 can be a snap structure that cooperates with each other.

[0038] In some specific embodiments, one of the first support member 4 and the second support member 5 is provided with a slot 41, and the other of the first support member 4 and the second support member 5 is provided with a protrusion 51. The protrusion 51 is inserted into the slot 41, which facilitates the disassembly and installation of the first support member 4 and the second support member 5.

[0039] In some specific embodiments, the first support member 4 is provided with a guide post 43, and the second support member 5 is provided with a guide hole. The guide post 43 and the guide hole cooperate with each other. The guide post 43 can play a guiding role, which facilitates the disassembly and installation of the first support member 4 and the second support member 5.

[0040] In some specific embodiments, the first support member 4 includes a first surface facing the second support member 5. A gasket 6 is provided between the flexible circuit board 3 and the first surface, which can improve the stability of the flexible circuit board 3. The first support member 4 and the second support member 5 fix the flexible circuit board 3.

[0041] In some specific embodiments, the keyboard end housing 1 is provided with a mounting seat. The first support member 4 is provided with a first mounting hole, and the second support member 5 is provided with a second mounting hole. The fastener 7 sequentially passes through the second mounting hole and the first mounting hole and is connected to the mounting seat, which has the advantage of simple installation and disassembly.
