Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] As a specific embodiment of this utility model:

[0034] First embodiment: Refer to Figure 1-4 The keyboard upper shell 100 and keyboard bottom shell 200 are fixed together by buckles and screws. The first magnet 1-1 and the second magnet 1-2 attract each other to make the left keyboard 10 and right keyboard 30 more stable when opened. The second linkage block 62 at both ends of the keyboard rotates 180° around the pin, which drives the left keyboard 10, right keyboard 30 and the second linkage plate 65 to achieve a three-fold fold with the keyboard body 20. The linkage bar 63 is snapped together with the first linkage plate 64 and the second linkage plate 65. After folding, the third magnet 1-3 at the front and rear ends of the keyboard body 20 attracts the fourth magnet 1-4 on the left keyboard 10 and right keyboard 30, thereby fixing the keyboard. After the PCBA1 senses the Hall magnet 9, it will automatically close the keyboard. The FPC4, key core conductive film 5 and light guide plate 11 inside the keyboard are fixed together by iron sheet 12 (stainless steel pad). The tail of the FPC4 is connected to the PCBA1 to conduct electricity.

[0035] Second embodiment: Refer to Figure 5-8The left keyboard 10, right keyboard 30, and keyboard body 20 are assembled and connected by rotating washers 7, first screw posts 81, and second screw posts 82. The conductive films 5 and FPC4 at both ends of the keyboard are aligned and connected by gold fingers, positioned by guide posts 15, and then fixed by iron plates 12 (locking conductive films) and silicone pads 16 by screws. The other end of FPC4 passes through the guide posts 15 on both sides of the keyboard fixing plate 3 and is inserted into the connector on PCBA1, making it more resistant to bending. The conductive films 5 on the keyboard body 20 are directly inserted into the connector on PCBA1, realizing the electrical connection of the three areas of the folding keyboard. The middle of the folding leather case 300 is fixed to the second buckle 2-2 on the keyboard body 20 by the first buckle 2-1 on the inner side. The two ends of the folding leather case 300 are connected by the third buckle 2-3 and the fifth magnet 1-5 at both ends, which cooperate with the slide groove 17 and the sixth magnet on the left keyboard 10 and right keyboard 30 to realize the opening and folding of the product.

[0036] Third embodiment: Refer to Figure 9-10 The left keyboard 10, right keyboard 30, and keyboard body 20 are assembled and connected via rotating washers 7, first screw posts 81, and second screw posts 82. The conductive film 5 (located on the right keyboard 30) is directly inserted into the touchpad assembly 18 (without numeric display) connector. One end of the FPC4 (below the right keyboard 30) is inserted into the touchpad assembly 18 (without numeric display) connector, and the other end passes through the guide post 15 and is inserted into the connector on PCBA1, thus realizing the connection between the folding key core 2, the touchpad assembly 18, and PCBA1. The conductive film 5 (on the left keyboard 10) is aligned with one end of the FPC4 and connected by gold fingers, positioned by the guide post 15, and then secured by the iron sheet 12 (locking the conductive film) and the silicone pad 16 through screws. The FPC4 is tightened and fixed, and the other end of the FPC4 passes through the guide post 15 on the keyboard fixing plate 3 and is inserted into the connector on the PCBA1. The guide post 15 makes the keyboard more resistant to bending. The conductive film 5 of the key core in the middle of the keyboard (i.e. on the keyboard body 20) is directly inserted into the connector on the PCBA1 to realize the electrical connection of the three areas of the folding keyboard (left keyboard 10, keyboard body 20 and right keyboard 30). The middle of the folding leather case 300 is fixed to the second buckle 2-2 on the keyboard body 20 by the first buckle 2-1 on the inner side. The two ends of the folding leather case 300 are connected to the slide groove 17 and the sixth magnet on the left keyboard 10 and right keyboard 30 by the third buckle 2-3 and the fifth magnet at both ends to realize the connection between the product in the open and folded state.

[0037] Fourth embodiment: Refer to Figure 9-11 The difference from the third embodiment is that the touchpad assembly 18 in this embodiment is a digital display touchpad assembly, and the rest is the same as the third embodiment.

[0038] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
