[0037] As Figures 1 to 3As shown, a flexible circuit board 1 according to the present invention includes a first main body section 11, a first connecting portion 12 connected to one end of the first main body section 11 and perpendicular to the first main body section 11, a second main body section 13 connected to and perpendicular to the first connecting portion 12 at one end, a second connecting portion 14 connected to and perpendicular to the other end of the second main body section 13, a third main body section 15 connected to and perpendicular to the second connecting portion 14 at one end, a non-folding terminal 16 connected to the other end of the first main body section 11, and a foldable folding terminal 17 connected to one side of the non-folding terminal 16; the second main body section 13 extends from the first connecting portion 12 to the other end of the first main body section 11, and the third main body section 15 extends from the second connecting portion 14 to the second main body section. 13 extends from the other end; the first connecting portion 12 includes a first bonding block 121 provided at the end of one end of the first main segment 11 and bonded to one end of the first main segment 11, a second bonding block 122 provided at the end of one end of the second main segment 13 and bonded to the first bonding block 121, and a third bonding block 123 provided on one side of the second bonding block 122; the second connecting portion 14 includes a fourth bonding block 141 provided at the end of one end of the third main segment 15 and bonded to one end of the third main segment 15, a fifth bonding block 142 provided at the end of the other end of the second main segment 13 and bonded to the fourth bonding block 141, and a sixth bonding block 143 provided on one side of the fifth bonding block 142.

[0038] The flexible circuit board 1 of the present invention facilitates quick and easy deployment, further enhancing the stability and reliability of the deployed flexible circuit board 1. In particular, the provision of the third adhesive block 123 and the sixth adhesive block 143 prevents peeling of the bond between the first connecting portion 12 and the second connecting portion 14 after deployment, ensuring a stable and reliable connection.

[0039] like Figure 1 and Figure 2 As shown, a long first folding hole 124 is provided on the folding line between the second adhesive block 122 and the third adhesive block 123; and a long second folding hole 144 is provided on the folding line between the fifth adhesive block 142 and the sixth adhesive block 143. The provision of the first folding hole 124 and the second folding hole 144 makes it easier to fold the third adhesive block 123 and the sixth adhesive block 143.

[0040] The unfolding process of the main section of the flexible circuit board 1 includes the following steps.

[0041] Step 1: If Figure 1 As shown, after the first main body segment 11 is flipped 180 degrees to the right along the first flipping direction 191 with the boundary line between the first main body segment 11 and the first connecting portion 12 as the axis, one end of the first main body segment 11 overlaps and is bonded to the first bonding block 121 .

[0042] Step 2: As shown in Figure 1 the first body section 11 is adhered to the second adhesive block 122. Thus, the first body section 11 is substantially located on the extension line of the second body section 13.

[0043] Step 3: As shown in Figure 1 the third adhesive block 123 is adhered to the back of the portion of the first connecting section 12 having the first adhesive block 121. Thus, the adhesion between the first adhesive block 121 and the second adhesive block 122 is not easily peeled off, and the connection between the first body section 11 and the second body section 13 is more stable.

[0044] Step 4: As shown in Figure 2 the third body section 15 is adhered to the fourth adhesive block 141. Thus, the third body section 15 is substantially located on the extension line of the second body section 13.

[0045] Step 5: As shown in Figure 2 the third body section 15 is adhered to the fifth adhesive block 142. Thus, the third body section 15 is substantially located on the extension line of the second body section 13.

[0046] Step 6: As shown in Figure 2 the fourth adhesive block 141 and the fifth adhesive block 142 is not easily peeled off, and the connection between the third body section 15 and the second body section 13 is more stable.

[0047] As shown in Figure 4 and Figure 5As shown, the folding step of the folding terminal 17 is that the folding terminal 17 is folded to the non-folding terminal 16 in the way that the folding terminal 17 is turned down one hundred and eighty degrees in the seventh turning direction 197, and then the folding terminal 17 and the non-folding terminal 16 are overlapped. This step can be completed before the main body section is unfolded, or can be completed after the main body section is unfolded.

[0048] Through the above steps, the flexible circuit board 1 is unfolded into a super-long strip-shaped flexible circuit board 1 as shown. Figure 3

[0049] Of course, the skilled in the art can also continue to add the main body section behind the third main body section 15 according to the needs.

Then, the driving device 305 drives the ring-shaped driven member 303 to rotate one hundred and eighty degrees, the ring-shaped guide member 302 controls the trajectory and the rotation direction of the ring-shaped driven member 303, and the ring-shaped second support member 304 rotates one hundred and eighty degrees along with the rotation of the ring-shaped driven member 303, thereby driving the folding terminal fixing member 340 to rotate one hundred and eighty degrees. Thus, the folding terminal 17 fixed on the folding terminal fixing member 340 completes one hundred and eighty degrees turning, and the folding step of the folding terminal 17 is automatically completed.

[0063] The non-folded terminal fixing plate 311 can be integrally formed with the annular first support member 301, or can be separately formed and then mounted on the annular first support member 301. The bottom of the non-folded terminal fixing plate 311 can be provided only with the first non-folded terminal fixing block 312, or can be provided with the second non-folded terminal fixing block 313, or can be provided with a third non-folded terminal fixing block (not shown) according to the needs.

[0069] The driving gear 353 and the driven gear 332 are engaged. When the driving device 305 drives the driving gear 353 to rotate, the driven gear 332 engaged with the driving gear 353 is driven to rotate forward or rotate reversely by one hundred and eighty degrees, so that the folded terminal positioning plug 344 can rotate forward or rotate reversely by one hundred and eighty degrees, thereby completing the automatic folding action of the folded terminal 17.

[0070] As shown in Figure 6 , 7 and 10, the terminal automatic folding device 300 further comprises a mounting base 391, a mounting plate 392 perpendicular to the mounting base 391 and fixed on the mounting base 391, a fixing plate 393 fixed on the mounting plate 392, and a reinforcing plate 394 for increasing the strength of the mounting plate 392.

In this embodiment, the terminal automatic folding device 300 can further comprise a mounting base sliding block 397. By arranging the mounting base sliding block 397, the terminal automatic folding device 300 can move on a set track (not shown). For example, when it is desired that the terminal automatic folding device 300 moves in a direction perpendicular to the rotation plane of the annular second supporting member 304, a track perpendicular to the rotation plane of the annular second supporting member 304 can be arranged, so that the terminal automatic folding device 300 can move along the track through the mounting base sliding block 397.
