[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] It should be understood that when used in this specification and the appended claims, the terms "include" and "comprises" indicate the presence of described features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or combinations thereof.

[0036] It should also be understood that the terms used in this utility model specification are only for the purpose of describing specific embodiments and are not intended to limit the utility model. As used in this utility model specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0037] It should be further understood that the term “and / or” used in the present specification and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0038] See also Figures 1 to 12 The specific embodiment of the utility model discloses a card-type magnetic folding bracket, including a card layer 1 and a folding layer 2, the card layer 1 is provided with a magnetic attraction part 11, a damping shaft 3 is provided between the card layer 1 and the folding layer 2, the card layer 1 and the folding layer 2 are rotatably connected through the damping shaft 3, and the card layer 1 and the folding layer 2 can rotate relative to each other to any angle.

[0039] Specifically, in this embodiment, the folding bracket uses the magnetic attraction member 11 on the card layer 1 to absorb the mobile device, and the operation mechanism of the damping shaft 3 in the folding bracket mainly depends on the damping structure inside it. This design of the damping shaft 3 enables the card layer 1 and the folding layer 2 to rotate relative to each other and achieve stable locking at any angle. Specifically, the damping shaft 3 includes a shaft core and a damping material inside, and the damping material includes gears, springs, and damping plates. These components work together to achieve rotation and damping functions. When an external force is applied to rotate the folding layer 2 relative to the card layer 1, the gears inside the damping shaft 3 start working, allowing relative movement between the two. At the same time, components such as damping plates or springs provide a certain resistance, so that the rotation process is not too easy, but requires a certain amount of force to change the angle. More importantly, this damping design allows the damping shaft 3 to be locked at any angle. This means that when a specific rotation angle is reached, the damping force will suddenly increase, so that the card layer 1 and the folding layer 2 can be stably maintained at the angle without easily changing position due to a slight external force. Therefore, the damping shaft 3 not only realizes the rotation function of the folding bracket, but also ensures the stability and usability of the bracket through its unique damping mechanism. Users can easily adjust the angle between the card layer 1 and the folding layer 2 as needed, and achieve stable fixation at any angle to meet different usage requirements.

[0040] like Figure 2-3 As shown, a pocket-type interlayer is provided on the top of the card layer 1, and a magnetic attraction part 11 is built in the interlayer. The other side of the interlayer is a magnetic attraction part 12. The magnetic attraction part 12 is aligned with a mobile phone or a mobile phone case with a magnetic attraction function so that the folding bracket can be adsorbed on the mobile phone or the mobile phone case. The user does not need to use additional fixing devices or tools, but only needs to bring the bracket close to the magnetic position of the mobile phone to achieve a quick and stable connection. In addition, due to the characteristics of the magnetic connection, the user can easily remove the bracket from the mobile phone or reposition it to adapt to different usage scenarios and needs.

[0041] like Figure 4 As shown, the folding layer 2 is divided into a first support plate 21 and a second support plate 22 . Only one edge of the second support plate 22 is flexibly connected to the first support plate 21 . One edge of the second support plate 22 is end-to-end connected to an edge of the first support plate 2 .

[0042] Specifically, the second support plate 22 can rotate around an edge of the first support plate 21. In order to meet the flexibility of the folding bracket, if more than one edge of the second support plate 22 is connected to the first support plate 21, the movement of the second support plate 22 will be restricted to a certain extent, so that the second support plate 22 loses its supporting function, and the function of the folding bracket will be reduced to a certain extent.

[0043] like Figure 1 , Figure 4 and Figure 6 As shown, the second support plate 22 has four radial folds radiating from a point near the geometric center of the second support plate 22 to the surrounding areas. The second support plate 22 is divided into four panels that can be folded with each other through the four radial folds, which are divided into a first folding surface 221, a second folding surface 222, a third folding surface 223 and a fourth folding surface 224.

[0044] Specifically, in the present embodiment, the second support plate 22 is designed to be four support panels that can be folded with each other. After the first support plate 21 is adsorbed to the mobile terminal 4 by the magnetic attraction member 11, in addition to changing the angle between the first support plate 21 and the second support plate 22 by the damping shaft 3 to form a support structure to support the mobile terminal 4, the first folding surface 221, the second folding surface 222, the third folding surface 223 and the fourth folding surface 224 can be folded to form another support structure without changing the angle between the first support plate 21 and the second support plate 22. When the second support member is rotated to form an angle with the horizontal plane, the first folding surface 221, the second folding surface 222, the third folding surface 223 and the fourth folding surface 224 can be folded to form another support structure for the mobile terminal 4 with the second support plate 22. In summary, the special folding structure design of the second support plate 22 greatly improves the flexibility and diversity of the folding bracket support structure.

[0045] like Figure 1 and Figure 6 As shown, the first folding surface 221 and the fourth folding surface 224 are trapezoidal, and the second folding surface 222 and the third folding surface 223 are triangular.

[0046] Specifically, in other embodiments, each folding surface may also be other regular shapes, and the specific shape may be set according to actual conditions.

[0047] like Figure 1 and Figure 6 As shown, the four radial creases are divided into a first crease line 225, a second crease line 226, a third crease line 227 and a fourth crease line 228. When the second support plate 22 is in a fully unfolded state, the second support plate 22 is attached to the first support plate 21, and the second support plate 22 is consistent in shape and equal in size to the first support plate 21.

[0048] Specifically, when the second support plate 22 is in a fully unfolded state, the second support plate 22 and the first support plate 21 are in the same plane and fit each other. At the same time, the four crease lines are coplanar at this time and intersect at one point. Such a design not only allows the second support plate 22 to remain stable when unfolded, but also enables each panel to be folded according to the preset crease lines when the second support plate 22 is folded, forming different shapes and angles, thereby realizing a variety of usage modes and support angles of the bracket.

[0049] like Figure 1 and Figure 6 As shown, the angle between the first crease line 225 and the third crease line 227 is 180°, the angle between the third crease line 227 and the fourth crease line 228 is 120°-160°, and the angle between the first crease line 225 and the fourth crease line 228 is 30°-60°.

[0050] Specifically, the angle between the first crease line 225 and the third crease line 227 is 180°, which means that the two crease lines are actually two parts on the same straight line, and they form a straight crease on the second support plate 22. This helps to ensure that when the second support plate 22 is folded or unfolded, the two parts can transition smoothly without forming sharp angles, thereby improving the comfort of use of the bracket. At the same time, the angle between the third crease line 227 and the fourth crease line 228 ranges from 120° to 160°, and the angle between the first crease line 225 and the fourth crease line 228 ranges from 30° to 60°. These angle ranges limit the shape change of the second support plate 22 when folded. Such a design enables the second support plate 22 to maintain a certain stability and structural strength when folded into different shapes, and can also adapt to the support requirements of different mobile phones or devices.

[0051] like Figure 5 and Figure 8-9 As shown, when the second folding plate is in the folded state, the first folding surface 221 , the second folding surface 222 and the third folding surface 223 can all be bent toward the fourth folding surface 224 to form a variety of support structures at different angles.

[0052] Specifically, this embodiment shows two supporting structures to support the mobile terminal 4, such as Figure 5 and Fig. 9 As shown, after the first folding surface 221 is folded to fit the fourth folding surface 224, the second folding surface 222 and the third folding surface 223 are bent upward toward the fourth folding surface 224. At this time, the second folding surface 222, the third folding surface 223 and the fourth folding surface 224 are enclosed together to form a supporting structure, as shown in FIG. Fig. 9The mobile phone placed horizontally in the middle can be stably supported on the horizontal plane in an inclined state under the joint action of the second folding surface 222, the third folding surface 223, the fourth folding surface 224 and the horizontal plane; in addition, Figure 8 As shown, after the vertically placed mobile phone is rotated a certain angle on the second support plate 22 around the damping shaft 3, the second support plate 22 forms a support frame. If the folding panels in the second support plate 22 are in the initial unfolded state, the second support plate 22 is prone to overturning due to uneven force. After the first folding surface 221, the second folding surface 222 and the third folding surface 223 are folded to a certain angle, they and the fourth folding surface 224 can form a stable support structure, thereby supporting the mobile phone to a certain height, thereby enhancing the user experience.

[0053] like Fig.10 As shown, in another embodiment, the first folding surface 221a is a pentagon with two adjacent right angles, and the second folding surface 222a, the third folding surface 223a and the fourth folding surface 224a are all triangles.

[0054] like Fig.10 As shown, the included angle between the first crease line 225a and the fourth crease line 228a is 120° to 160°.

[0055] Specifically, after the first folding surface 221a, the second folding surface 222a, the third folding surface 223a and the fourth folding surface 224a are replaced with another shape, the mobile terminal 4 can be placed at more angles when the second support plate 22 is in the folded state, greatly increasing the diversity of the folding bracket.

[0056] like Fig. 9 and Fig.12 As shown, when the second support plate 22 is in a folded state, any two folded surfaces that are in contact with each other are respectively provided with magnetic members 229 .

[0057] Specifically, in this embodiment, the magnetic member 229 is a magnet, and in other embodiments, it can be set to other magnetic objects, which can be set according to actual conditions. Since the two folding surfaces that fit together are respectively provided with magnetic members 229, this feature provides a magnetic attraction function for the folding bracket, so that in the folded state, different folding surfaces can attract each other through magnetism and remain stable, thereby enhancing the stability and convenience of use of the bracket, and the provision of the magnetic member 229 enables the folding bracket to automatically absorb and maintain a specific folding state without the need for additional fixings, which simplifies the use process of the bracket and improves its flexibility and convenience of use.

[0058] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
