[0032] The following is a preferred embodiment of a folding device provided by this utility model that can solve the above-mentioned technical problems.

[0033] Please refer to Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 ,in Figure 1 This is a perspective view of the folding device of this utility model. Figure 4 This is a perspective view of the first flap of the folding device of this utility model. Figure 5 This is a top view of the unfolded state of the folding device of this utility model.

[0034] In the diagram, units with similar structures are represented by the same labels.

[0035] The terms "first" and "second" in this utility model are used for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as a restriction on the order of events.

[0036] This utility model provides a folding device, including a bidirectional connecting rod 11, a first flap 12 and a second flap 13 located on both sides of the bidirectional connecting rod 11 and rotatable relative to the bidirectional connecting rod 11, and connecting plates 14 located at both ends of the bidirectional connecting rod 11 for connecting the first flap 12 and the second flap 13 to the bidirectional connecting rod 11. The first flap 12 and the second flap 13 each have multiple slots 122 on the side closest to the bidirectional connecting rod 11 that engage with the bidirectional connecting rod 11. These slots 122 are arc-shaped and respectively located on the first flap 12 and the second flap. On 13, the folding device is used to install inside foldable mobile phones and foldable tablets, etc. The fixing plate 113 is used to connect the first flip cover 12 and the second flip cover 13 to the bidirectional connecting rod 11, so as to facilitate the rotation of the first flip cover 12 and the second flip cover 13 on the bidirectional connecting rod 11. When the first flip cover 12 flips on the bidirectional connecting rod 11, the slot 122 of the first flip cover 12 abuts against the bidirectional connecting rod 11 when the first flip cover 12 is rotating. The bidirectional connecting rod 11 limits the slot 122 of the first flip cover 12 to prevent the first flip cover from being stopped when it is not rotating. The first flip cover 12 rotates on its own. Because multiple arc-shaped slots 122 are arranged on the first flip cover 12, when the slots 122 at different angles abut against the bidirectional connecting rod 11, the bidirectional connecting rod 11 engages within the slots 122 of the first flip cover 12, allowing the first flip cover 12 to hover at a specific angle on the bidirectional connecting rod 11. Similarly, when the second flip cover 13 rotates, the same principle applies. Because multiple arc-shaped slots 122 are arranged on the second flip cover 13, when the slots 122 at different angles abut against the bidirectional connecting rod 11… The bidirectional connecting rod 11 is engaged in the slot 122 of the first flip cover 12 so that the second flip cover 13 can be suspended on the bidirectional connecting rod 11 at a specific angle. Similarly, the first flip cover 12 and the second flip cover 13 can also rotate at the same time, and the first flip cover 12 and the second flip cover 13 can also be suspended on the bidirectional connecting rod 11 at different angles. Through the above operations, the structure of the first flip cover 12 and the second flip cover 13 being suspended on the bidirectional connecting rod 11 is simple. Users can suspend the first flip cover 12 and the second flip cover 13 at a specific angle on the bidirectional connecting rod 11, making the folding device more flexible in suspension.

[0037] Please refer to Figure 2 and Figure 3 , Figure 2 The three-dimensional bidirectional connecting rod of the folding device of this utility model Figure 1 , Figure 3 The three-dimensional bidirectional connecting rod of the folding device of this utility model Figure 2The bidirectional connecting rod 11 includes a first connecting rod 111, a second connecting rod 112 located on one side of the first connecting rod 111, a fixing plate 113 located between the first connecting rod 111 and the second connecting rod 112 for fixing the first connecting rod 111 and the second connecting rod 112, and a rubber sleeve 115 sleeved on the first connecting rod 111 and the second connecting rod 112. The corner of the rubber sleeve 115 is used to engage the slots 122 of the first flip cover 12 and the second flip cover 13. The fixing plate 113 is used to hold the first connecting rod 111... The first flip cover 12 and the second connecting rod 112 form a whole. The rubber sleeve 115 is used to limit the first flip cover 12 and the second flip cover 13. When the strip groove 122 of the first flip cover 12 is connected to the corner of the rubber sleeve 115 or the strip groove 122 of the second flip cover 13 is connected to the corner of the rubber sleeve 115, the corner of the rubber sleeve 115 limits the strip groove 122 of the first flip cover 12 and the strip groove 122 of the second flip cover 13 so that the first flip cover 12 and the second flip cover 13 can be suspended on the rubber sleeve 115.

[0038] The bidirectional connecting rod 11 also includes a fixed protrusion 114 located between the first connecting rod 111 and the second connecting rod 112. The rubber sleeves 115 are located at both ends of the fixed protrusion 114. The fixed protrusion 114 is used to limit the rubber sleeves 115 at both ends to prevent the rubber sleeves 115 from being too long when connected to the first connecting rod 111 and the second connecting rod 112, and to stabilize the first flip cover 12 and the second flip cover 13 when flipping on the rubber sleeves 115.

[0039] The first connecting rod 111, the second connecting rod 112, and the fixing plate 113 are in the shape of an I-beam. The rubber sleeve 115 has a first groove that matches the I-beam shape. The rubber sleeve 115 is fitted onto the first connecting rod 111, the second connecting rod 112, and the fixing plate 113 through the first groove. The first connecting rod 111, the second connecting rod 112, and the fixing plate 113 are located in the first groove of the rubber sleeve 115. Since the I-beam shaped first connecting rod 111, the second connecting rod 112, and the fixing plate 113 are used to limit the rubber sleeve 115, the rubber sleeve 115 is prevented from rotating when the first flip cover 12 and the second flip cover 13 rotate on the rubber sleeve 115, so that the rotation of the first flip cover 12 and the second flip cover 13 is more stable.

[0040] When the first flip cover 12 or the second flip cover 13 is flipped, each strip groove 122 is interference-fitted with the rubber sleeve 115. When the strip groove 122 is interference-fitted with the rubber sleeve 115, it can effectively prevent the first flip cover 12 and the second flip cover 13 from rotating on the rubber sleeve 115, and further facilitate the first flip cover 12 and the second flip cover 13 to be suspended on the bidirectional connecting rod 11.

[0041] Please refer to Figure 9 , Figure 9This is a perspective view of the connecting plate of the folding device of this utility model. The connecting plate 14 is provided with symmetrical first through holes 141 and second through holes 142 located on one side of the first through holes 141. The second through holes 142 and the first through holes 141 are inclined. The first through holes 141 are connected to the first connecting rod 111 and the second connecting rod 112 respectively. The first flip cover 12 and the second flip cover 13 are provided with connecting posts 123 that are snapped into the second through holes 142 on both sides. The first through holes 141 are used to facilitate the connection of the first connecting rod 111 and the second connecting rod 112 to the connecting plate 14. The second through holes 142 are used to facilitate the connection of the first flip cover 12 and the second flip cover 13 to the connecting plate 14, so that the first flip cover 12 and the second flip cover 13 can rotate on the rubber sleeve 115.

[0042] Please refer to Figure 4 , Figure 4 This is a perspective view of the first flap of the folding device of this utility model. Both sides of the first flap 12 and the second flap 13 are provided with relief grooves 124. The connecting plate 14 is located in the relief grooves 124. The relief grooves 124 are used to place the connecting plate 14. When the connecting plate 14 is located in the relief grooves 124, it is used to hide the connecting plate 14 in the first flap 12 and the second flap 13, thereby reducing the volume of the folding device.

[0043] The lower part of the first flip cover 12 and the second flip cover 13 near the bidirectional connecting rod 11 is a vertical plane. When the first flip cover 12 and the second flip cover 13 are unfolded, the plane is in contact with the rubber sleeve 115. The vertical plane is used to contact the side wall of the rubber sleeve 115. When the vertical plane of the first flip cover 12 and the vertical plane of the second flip cover 13 are in contact with the side wall of the rubber sleeve 115, the first flip cover 12 and the second flip cover 13 are in an open state to prevent the first flip cover 12 and the second flip cover 13 from continuing to open.

[0044] The folding device is also provided with a soft rubber plate 15. The two sides of the soft rubber plate 15 are respectively connected to the first flip cover 12 and the second flip cover 13. The soft rubber plate 15 is used to connect the first flip cover 12 and the second flip cover 13 into a whole, so that the first flip cover 12 and the second flip cover 13 can be rotated at the same time.

[0045] The first flap 12 and the second flap 13 are respectively provided with a second groove 121. The two sides of the soft rubber plate 15 are respectively located in the second groove 121. The second groove 121 of the first flap 12 and the second groove 121 of the second flap 13 are both used to place the soft rubber plate 15, hiding the soft rubber plate 15 in the first flap 12 and the second flap 13, further reducing the volume of the folding device.

[0046] Working principle:

[0047] When assembling the folding device, firstly, the two ends of the first connecting rod 111 and the second connecting rod 112 are respectively inserted into the first groove of the rubber sleeve 115 to fit the rubber sleeve 115 onto the first connecting rod 111 and the second connecting rod 112. Since the first connecting rod 111, the second connecting rod 112, and the fixing plate 113 are in an I-shape, the rubber sleeve 115 can prevent the rubber sleeve 115 from rotating on its own when fitted onto the first connecting rod 111 and the second connecting rod 112. Next, the first connecting rod 111 and the second connecting rod 112 are inserted into the first through hole 141 of the connecting plate 14, and the connecting post 123 of the first flip cover 12 and the connecting post 123 of the second flip cover 13 are respectively installed in the second through hole 142 of the connecting plate 14 to connect the first flip cover 12 and the second flip cover 13 to the bidirectional connecting rod 11. This also facilitates the rotation of the first flip cover 12 and the second flip cover 13 on the bidirectional connecting rod 11. Finally, the soft rubber plate 15 is fixed to the first flip cover 12. The first flip cover 12 and the second flip cover 13 can be rotated within the second groove 121. When the first flip cover 12 and the second flip cover 13 are rotated, taking the first flip cover 12 as an example, when the first flip cover 12 is rotated, the strip groove 122 of the first flip cover 12 engages with the corner of the rubber sleeve 115, and the rubber sleeve 115 is press-fitted with the strip groove 122, so that the first flip cover 12 is suspended on the bidirectional connecting rod 11 at a specific angle. When the first flip cover 12 is rotated, since multiple strip grooves 122 are arranged in an arc shape on the first flip cover 12, when the first flip cover 12 is rotated, the corner of the rubber sleeve 115 moves from the strip groove 122 to the adjacent strip groove 122, so that the first flip cover 12 is suspended on the bidirectional connecting rod 11 at another angle when it is rotated. The same operation as the first flip cover 12 can be repeated when the second flip cover 13 is rotated. Through the above operation, the user can suspend the first flip cover 12 and the second flip cover 13 at a specific angle on the bidirectional connecting rod 11, making the folding device more flexible in suspension.

[0048] In this preferred embodiment, when the folding device rotates via the first or second flip cover, multiple strip slots at different angles engage with the bidirectional connecting rod. The bidirectional connecting rod limits the strip slots of the first and second flip covers respectively, so that the first and second flip covers can be suspended at different angles on the bidirectional connecting rod, making the folding device more flexible in its suspension.

[0049] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
