[0033] Embodiment 1

[0034] Please refer to Figure 1and Figure 2 A driving board for a double - screen flip - up display provided by the present utility model, which comprises a circuit board substrate 1.

The cross - sectional shapes of the first circuit boards 11 and the second circuit boards 12 are both "C" - shaped. The first circuit boards 11 face rightward, and the second circuit boards 12 face leftward. The first circuit boards 11 and the second circuit boards 12 are interlaced and buckled with each other, and a plurality of first circuit boards 11 and second circuit boards 12 are interlaced and buckled with each other and arranged in an array. Since the first circuit boards 11 face rightward while the second circuit boards 12 face leftward, and the first circuit boards 11 and the second circuit boards 12 are interlaced and buckled with each other, a plurality of first circuit boards 11 and second circuit boards 12 are combined into a unit and arranged in an array, so that less window - opening material is removed after the first circuit boards 11 and the second circuit boards 12 are buckled, thereby reducing material waste during the production of large boards, further reducing product costs, and improving the competitiveness of products.

[0035] Embodiment 2

[0036] Please refer to Figure 3 and Figure 4 As a further optimized solution of Embodiment 1, in this embodiment, a third circuit board 13 is arranged above the first circuit board 11, and a fourth circuit board 14 is arranged above the second circuit board 12. The cross - sectional shapes of the first circuit board 11, the second circuit board 12, the third circuit board 13, and the fourth circuit board 14 are all "C" - shaped and the numbers are equal. The third circuit board 13 faces rightward, and the fourth circuit board 14 faces leftward. The second circuit board 12 is buckled between the first circuit board 11 and the third circuit board 13, and the third circuit board 13 is buckled between the second circuit board 12 and the fourth circuit board 14. A plurality of first circuit boards 11, second circuit boards 12, third circuit boards 13, and fourth circuit boards 14 are combined into a unit and arranged in an array, and the fourth circuit board 14 is buckled between the third circuit board 13 and the first circuit board 11 of the next array. Compared with Embodiment 1, it has a higher space utilization rate and less window - opening material is removed, thereby reducing material waste during the production of large boards, further reducing product costs, and improving the competitiveness of products.

[0037] Embodiment 3

[0038] Please refer to Figure 5, as a further optimized solution of Embodiment 1, in this embodiment, the first circuit board 11 includes a body 111, a reinforcing plate 112 and a connector 113. The reinforcing plate 112 is fixed to the upper surface of the end of the body 111. Fixing parts 114 extend outward from both ends of the reinforcing plate 112. Both fixing parts 114 extend beyond the edge of the body 111. First strong magnetic blocks 115 are fixed to the lower surfaces of the two fixing parts 114; the connector 113 is arranged below the body 111, and two second strong magnetic blocks 116 corresponding to the two first strong magnetic blocks 115 are fixed on the connector 113. Since the reinforcing plate 112 is fixed to the upper surface of the body 111, the first strong magnetic blocks 115 are fixed to both ends of the reinforcing plate 112, and the two second strong magnetic blocks 116 corresponding to the two first strong magnetic blocks 115 are fixed on the connector 113. When the body 111 and the connector 113 are installed, as long as the two ends of the body 111 are close to the connector 113, the first strong magnetic blocks 115 at both ends of the body 111 and the second strong magnetic blocks 116 at both ends of the connector 113 will attract and approach each other and be fixed. The body 111 and the connector 113 can achieve automatic alignment and tight connection. This assembly structure of the first circuit board 11 has fewer assembly steps. Only by approaching the body 111 and the connector 113 can the assembly be achieved. The assembly efficiency of the first circuit board 11 can be greatly improved, and the automatic assembly of the first circuit board 11 and the connector 113 can be easily realized. The fewer the assembly steps, the lower the probability of defective products of the first circuit board 11 during assembly. Thus, the situation where the product assembled with it cannot work properly due to poor assembly is avoided, thereby avoiding abnormal product operation, reducing the defective rate of the product, thus greatly reducing the production and manufacturing costs of the first circuit board 11, and further improving the product competitiveness of the first circuit board 11, so as to meet the increasing quality requirements of the enterprise.

[0039] Further, two grooves 117 are formed on the connector 113, and the two second strong magnetic blocks 116 are respectively fixed in the two grooves 117, so that the fitting of the body 111 and the connector 113 is more compact, improving the reliability of the assembly, thereby greatly reducing the production and manufacturing costs of the first circuit board 11, and further improving the product competitiveness of the first circuit board 11, so as to meet the increasing quality requirements of the enterprise.

[0040] Further, chamfers are provided at the edges of the grooves 117. More preferably, the chamfers are right angles or rounded corners, so that when the first strong magnetic block 115 approaches the second strong magnetic block 116, it can accurately fall into the groove 117 under the guiding action of the chamfers, improving the accuracy and reliability of the assembly, thereby greatly reducing the production and manufacturing costs of the first circuit board 11, and further improving the product competitiveness of the first circuit board 11.

[0041] Furthermore, the external dimensions of the second strong magnetic block 116 are larger than those of the first strong magnetic block 115, and the external dimensions of the groove 117 correspond to those of the first strong magnetic block 115 and the second strong magnetic block 116, so that the second strong magnetic block 116 can be firmly fixed in the groove 117. Even if the suction force of the first strong magnetic block 115 is large, the second strong magnetic block 116 will not be sucked out, improving the reliability of assembly. As a result, the production and manufacturing costs of the first circuit board 11 are greatly reduced, thereby improving the product competitiveness of the first circuit board 11 to meet the increasing quality requirements of enterprises.

[0042] Furthermore, the depth of the groove 117 is equal to the sum of the thicknesses of the first strong magnetic block 115 and the second strong magnetic block 116, so that the assembly of the body 111 and the connector 113 can be smoothly fitted without gaps. More preferably, a buffer pad can be provided on the contact surface between the body 111 and the connector 113, and a buffer groove corresponding to the buffer pad is opened on the connector 113, so as to obtain buffering during the fitting assembly and avoid damaging the body 111 or the connector 113. More preferably, the buffer pad is a rubber pad, which has good effects, low cost and high cost performance.

[0043] Furthermore, the materials of both the first strong magnetic block 115 and the second strong magnetic block 116 are neodymium iron boron strong magnets, and the neodymium iron boron strong magnet process is mature with high cost performance.

[0044] Furthermore, the colors of the first strong magnetic block 115 and the second strong magnetic block 116 are different, so that the staff can distinguish the first strong magnetic block 115 and the second strong magnetic block 116 during installation.

[0045] In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "connection", "fixation" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection, an electrical connection or communication with each other; it can be directly connected, or indirectly connected through an intermediate medium, and can be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0046] Obviously, the embodiments described above are only a part of the embodiments of this application, rather than all of them. The preferred embodiments of this application are shown in the drawings, but they do not limit the patent scope of this application. This application can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosed content of this application more thorough and comprehensive.
