[0027] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0028] In the various specific technical features described in the specific embodiments, they can be combined in any suitable manner without conflict. For example, different embodiments and technical solutions can be formed by combining different specific technical features. To avoid unnecessary repetition, various possible combination methods of the specific technical features in the present utility model will not be described separately.

[0029] In the following descriptions, the terms "first / second / etc." involved are only used to distinguish different objects and do not indicate that there are the same or related relationships between the objects. It should be understood that the orientation descriptions "above", "below", "outside", "inside" involved are all the orientations in the normal use state, and the "left" and "right" directions represent the left and right directions shown in the specific corresponding schematic diagrams, which can be the left and right directions in the normal use state or not.

[0030] It should be noted that the term "comprise", "include" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or apparatus comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or apparatus. Without further limitation, an element defined by the phrase "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or apparatus comprising that element. "Plurality" means greater than or equal to two.

[0031] An embodiment of the present utility model provides a bracket, as Figures 1-4 shown. The bracket includes a connecting arm 1, a first support 2 and a second support 3. The first support 2 is provided with a first magnetic member 22 (refer to Figure 4 ), and the first magnetic member 22 is used for magnetically connecting an electronic device. The types of electronic devices include but are not limited to mobile phones and tablet computers. The second support 3 is provided with a second magnetic member 32 (refer to Figure 4 ), and the second magnetic member 32 is used for magnetically connecting to a support surface. The support surface may be the surface of an object with ferromagnetic metal or alloy material such as a refrigerator, an induction cooker, or a magnetic member attached to a wall, so that the second support 3 can be adsorbed on the support surface. Of course, it can be understood that even if the support surface is the surface of an object without ferromagnetic metal or alloy material such as a desktop or a cabinet surface, as long as the second support 3 has a suitable support area, it can also abut against the support surface and support the first support 2, thereby supporting the electronic device connected to the first support 2. It should be noted that the type of application scenario of the embodiment of the present utility model does not limit the structure of the bracket provided by the embodiment of the present utility model.

[0032] As Figure 1 and Figure 2 shown, the first support 2 is connected to one end of the connecting arm 1 ( Figure 1 the upper end of the connecting arm 1) through a first damping rotating shaft 21, and the second support 3 is connected to the other end of the connecting arm 1 through a second damping rotating shaft 31 ( Figure 1The lower end of the connecting arm 1), and can at least support the first support 2. The connecting arm 1, the first support 2, and the second support 3 have a folded state and an unfolded state. Through the damping forces of the first damping rotating shaft 21 and the second damping rotating shaft 31, the first support 2 can rotate relative to the second support 3 by a certain angle and hover, so as to adjust the use angle of the electronic device to meet the user's use requirements. Specifically, the "folded state of the connecting arm 1, the first support 2, and the second support 3" means that, ignoring the thicknesses of the connecting arm 1, the first support 2, and the second support 3 themselves, the connecting arm 1, the first support 2, and the second support 3 are substantially parallel to each other, and the connecting arm 1 is arranged between the first support 2 and the second support 3; the "unfolded state of the connecting arm 1, the first support 2, and the second support 3" means that the first support 2 rotates relative to the second support 3 by a certain angle, so that there is an included angle between the connecting arm 1 and the first support 2, and / or there is an included angle between the connecting arm 1 and the second support 3.

[0033] Understandably, Figure 1 the shown bracket is in the unfolded state, Figure 2 the shown bracket is in the folded state. In the unfolded state and the folded state, the support surface can be the surface of an object with ferromagnetic metal or alloy material, that is, the second magnetic member 32 can be magnetically connected to the support surface; in the unfolded state and the folded state, the support surface can also be the surface of an object without ferromagnetic metal or alloy material, that is, the second magnetic member 32 can be not magnetically connected to the support surface, and only the bottom surface of the second support 3 abuts against the support surface and provides a supporting force to the first support 2.

[0034] For ease of understanding, an application scenario is provided in an embodiment of the present invention. In this application scenario, the bracket adsorbs the mobile phone through the first magnetic member 22 in the folded state and adsorbs on the vertical surface of the refrigerator through the second magnetic member 32. Due to the self-weight loads of the mobile phone and the first support 2, the first damping rotating shaft 21 and the second damping rotating shaft 31 are likely to overcome the damping forces and generate relative movement, so that the first support 2 is separated from the second support 3. And since the distance between the magnetic member and the surface to be adsorbed is negatively correlated with the magnitude of the magnetic adsorption force, in order to maintain the stability of the magnetic connection between the first magnetic member 22 and the electronic device, and the stability of the magnetic connection between the second magnetic member 32 and the support surface, the first magnetic member 22 is close to the side of the first support 2 away from the second support 3, and the second magnetic member 32 is close to the side of the second support 3 away from the first support 2. As Figure 4As shown, that is, the first magnetic member 22 is close to the upper surface of the first support 2, and the second magnetic member 32 is close to the lower surface of the second support 3. The distance between the first magnetic member 22 and the second magnetic member 32 is relatively large. Then, in the folded state, the magnetic adsorption force generated between the first magnetic member 22 and the second magnetic member 32 is also difficult to keep the connecting arm 1, the first support 2, and the second support 3 in the folded state, thus affecting the reliability of the support in this application scenario.

[0035] As Figure 4 shown, in the embodiment of the present invention, to overcome the defect of poor support reliability of the bracket in the folded state, the first support 2 is further provided with a first connecting member 23, and the second support 3 is further provided with a second connecting member 33. Thus, in the folded state, the first connecting member 23 and the second connecting member 33 are connected to each other, so that the relative positions between the first support 2 and the second support 3 are kept stable, and further the connecting arm 1, the first support 2, and the second support 3 can be kept in the folded state without loosening. With this arrangement, in the folded state, the first damping rotating shaft 21 (refer to Figure 1 ) and the second damping rotating shaft 31 (refer to Figure 1 ) provide damping forces, the first magnetic member 22 and the second magnetic member 32 can generate a magnetic adsorption force, and the first connecting member 23 and the second connecting member 33 are connected to each other to generate an attractive force, jointly keeping the connecting arm 1, the first support 2, and the second support 3 in the folded state, improving the stability of the bracket in the folded state, facilitating the user to use the bracket for support in the folded state, or facilitating the user to carry and store the bracket in the folded state.

[0036] Specifically, the first connecting member 23 and the second connecting member 33 can be magnetically connected. For example, one of the first connecting member 23 and the second connecting member 33 is a magnetic member, and the other of the first connecting member 23 and the second connecting member 33 is a magnetic member or an iron sheet. The first connecting member 23 and the second connecting member 33 can also be connected by vacuum adsorption. For example, one of the first connecting member 23 and the second connecting member 33 is a suction cup, and the other of the first connecting member 23 and the second connecting member 33 is an adsorption plane. The first connecting member 23 and the second connecting member 33 can also be adhesively bonded. For example, the first connecting member 23 and the second connecting member 33 are a set of magic tapes. It should be noted that no matter what structure the first connecting member 23 and the second connecting member 33 are set to, as long as the first connecting member 23 and the second connecting member 33 can be connected to each other in the folded state.

[0037] The bracket provided by the embodiment of the present utility model includes a connecting arm 1, a first support 2 and a second support 3. The connecting arm 1, the first support 2 and the second support 3 have a folded state and an unfolded state. The first support 2 is connected to one end of the connecting arm 1 through a first damping rotating shaft 21. The first support 2 is provided with a first magnetic member 22, and the first magnetic member 22 is used for magnetically connecting an electronic device. The second support 3 is connected to the other end of the connecting arm 1 through a second damping rotating shaft 31 and is at least used to support the first support 2. The second support 3 is provided with a second magnetic member 32, and the second magnetic member 32 is used for magnetically connecting a support surface. The first support 2 is further provided with a first connecting member 23, and the second support 3 is further provided with a second connecting member 33. In the folded state, the connecting arm 1 is located between the first support 2 and the second support 3, and the first connecting member 23 and the second connecting member 33 are connected. With such a setting, in the folded state, in addition to the damping forces of the first damping rotating shaft 21 and the second damping rotating shaft 31, and the magnetic adsorption force between the first magnetic member 22 and the second magnetic member 32, an attractive force that attracts each other can also be generated when the first connecting member 23 and the second connecting member 33 are connected, so that the relative positions between the first support 2 and the second support 3 are kept stable, thereby enabling the connecting arm 1, the first support 2 and the second support 3 to stably maintain the folded state, increasing the stability of the bracket in the folded state, so that it is convenient for the user to use the bracket for support in the folded state, or it is convenient for the user to carry and store the bracket in the folded state, and the design is ingenious.

[0038] In some embodiments, as Figure 5 and Figure 6 shown, the first support 2 is provided with a plurality of first connecting members 23, and the second support 3 is provided with a plurality of second connecting members 33. In the folded state, one first connecting member 23 and a corresponding one second connecting member 33 form a set of connecting groups 4 and are connected. Specifically, the connecting group 4 can be a magic tape group or a magnetic member group. With such a setting, a plurality of connecting groups 4 generate attractive forces that connect the first support 2 and the second support 3 at multiple positions, increasing the connection area between the first support 2 and the second support 3 in the folded state, and the resultant force generated by the plurality of connecting groups 4 is relatively large, which is beneficial to keeping the first support 2 and the second support 3 connected, and further improving the stability of the bracket in the folded state. It should be noted that for the convenience of reference, Figure 6 a perspective view of the second magnetic member 32 is shown.

[0039] In some embodiments, as Figure 7 shown, in the folded state, along the direction from the first damping rotating shaft 21 to the second damping rotating shaft 31, the first magnetic member 22 has a relatively arranged first end 222 and a second end 223, and the second magnetic member 32 has a relatively arranged third end 322 and a fourth end 323. In the present application Figure 7In the schematic diagram shown, the direction pointed by the arrow of N3 represents "the direction from the first damping rotating shaft 21 to the second damping rotating shaft", which is also Figure 7 the upward direction from bottom to top in the perspective view. In the folded state, the third end 322 and the first end 222 are spaced apart along the N3 direction, and the fourth end 323 and the second end 223 are spaced apart along the N3 direction. Specifically, the third end 322 is located below the first end 222, the fourth end 323 is located below the second end 223, the first magnetic member 22 is relatively close to the second damping rotating shaft 31, and the second magnetic member 32 is relatively close to the first damping rotating shaft 21.

[0040] Of course, in some possible implementation schemes, it may also be that the first end 222 and the third end 322 are spaced apart along the N3 direction, and the second end 223 and the fourth end 323 are spaced apart along the N3 direction. Specifically, in this implementation manner, the first end 222 is located below the third end 322, the second end 223 is located below the fourth end 323, the second magnetic member 32 is relatively close to the first damping rotating shaft 21, and the first magnetic member 22 is relatively close to the second damping rotating shaft 31.

[0041] It can be understood that no matter which of the above two implementation manners the first magnetic member 22 and the second magnetic member 32 are implemented, in the folded state, the orthographic projections of the first magnetic member 22 and the second magnetic member 32 in the thickness direction of the bracket do not coincide and are partially spaced apart. It can be simply understood that the first magnetic member 22 and the second magnetic member 32 are arranged staggeredly along the extending direction of the connecting arm 1. Such a setting increases the length of the bracket and also increases the extending length of the connecting arm 1, thereby increasing the lever arm length for the first support 2 to expand relative to the second support 3 (refer to Figure 1 ), so that the moving stroke of the electronic device connected to the first support 2 increases, the moving height of the electronic device increases, the positions increase, the flexibility of the bracket is higher, and it is more convenient for the user to use.

[0042] It should be noted that for the convenience of reference, Figure 7 in

[0043] In some embodiments, such as Figure 5 and Figure 6As shown, the first magnetic member 22 has a first axis 221, and the first magnetic member 22 is symmetrically arranged with respect to the first axis 221; the second magnetic member 32 has a second axis 321, and the second magnetic member 32 is symmetrically arranged with respect to the second axis 321. Specifically, the orthographic projections of the contours of the first magnetic member 22 and the second magnetic member 32 are all axisymmetric figures. For example, the orthographic projections of the contours of the first magnetic member 22 and the second magnetic member 32 can be figures such as circles, ellipses, squares, rectangles, isosceles triangles, and isosceles trapezoids. It should be noted that the specific structures and shapes of the first magnetic member 22 and the second magnetic member 32 are not limited in this application, as long as the first magnetic member 22 is symmetrically arranged with respect to the first axis 221 and the second magnetic member 32 is symmetrically arranged with respect to the second axis 321.

[0044] As Figure 4 and Figure 7 shown, in the folded state, both the first magnetic member 22 and the second magnetic member 32 are located between the respective connection groups 4, and both the first axis 221 and the second axis 321 extend along the thickness direction of the bracket. Then, the orthographic projection directions of the above-mentioned first magnetic member 22 and second magnetic member 32 represent the thickness direction of the bracket. The first axis 221 and the second axis 321 are arranged at intervals along the extension direction of the connecting arm 1. That is, in the folded state, the orthographic projections of the first magnetic member 22 and the second magnetic member 32 in the thickness direction of the bracket do not overlap and are spaced along the extension direction of the connecting arm 1, that is, the first magnetic member 22 and the second magnetic member 32 are staggered in the extension direction of the connecting arm 1. With this arrangement, both the first magnetic member 22 and the second magnetic member 32 are axisymmetric structures, and the first magnetic member 22 and the second magnetic member 32 have regular outer contours, which facilitates the first support 2 to set the limiting structure for installing the first magnetic member 22 and also facilitates the second support 3 to set the limiting structure for installing the second magnetic member 32, simplifying the assembly operation of the first magnetic member 22 and the second magnetic member 32.

[0045] In some embodiments, as Figure 4As shown, at least one of the first connecting member 23 and the second connecting member 33 is provided as a magnetic member and is magnetically connected to the other of the first connecting member 23 and the second connecting member 33. For example, the first connecting member 23 can be provided as a magnetic member and the second connecting member 33 can be provided as an iron sheet; the second connecting member 33 can be provided as a magnetic member and the first connecting member 23 can be provided as an iron sheet; or both the first connecting member 23 and the second connecting member 33 can be provided as magnetic members. With such a setting, magnetic adsorption force can be generated at every part of the magnetic member, and the area where the first connecting member 23 and the second connecting member 33 are adsorbed and connected is larger, so that the connection stability between the first connecting member 23 and the second connecting member 33 is higher, reducing the possibility that the first connecting member 23 and the second connecting member 33 are separated in the folded state, thereby causing the first support 2 and the second support 3 to be separated, and improving the stability of the bracket in the folded state. It can be understood that in the embodiment where the bracket is provided with multiple connecting groups 4, both the first connecting member 23 and the second connecting member 33 are provided as magnetic members, that is, the connecting group 4 is a magnetic member group, and the magnetisms of the first connecting member 23 and the second connecting member 33 in each connecting group 4 are opposite to each other.

[0046] In some embodiments, as Figure 7 shown, in the folded state, along the direction perpendicular to the extension direction of the connecting arm 1, at least two connecting groups 4 are respectively arranged on both sides of the connecting arm 1; and / or, in the folded state, along the extension direction of the connecting arm 1, at least two connecting groups 4 are respectively arranged adjacent to both ends of the connecting arm 1. For the convenience of explanation, the extension direction of the connecting arm 1 is defined as the N1 direction, and the direction perpendicular to the extension direction of the connecting arm 1 is defined as the N2 direction, that is, in the folded state, at least two of the multiple connecting groups 4 can be arranged at intervals along the N1 direction and are respectively arranged on both sides of the connecting arm 1 to increase the stability of the bracket in the N1 direction in the folded state and limit the freedom degree of relative movement of the first support 2 and the second support 3 in the N1 direction. In the folded state, at least two of the multiple connecting groups 4 can also be arranged at intervals along the N2 direction and are respectively arranged adjacent to both ends of the connecting arm 1 to increase the stability of the bracket in the N2 direction in the folded state.

[0047] Of course, as Figure 7 shown, in some possible implementation schemes, in the folded state, at least two connecting groups 4 can also be arranged at intervals along the N1 direction and are respectively arranged on both sides of the connecting arm 1, and at least two connecting groups 4 are arranged at intervals along the N2 direction and are respectively arranged adjacent to both ends of the connecting arm 1. It can be understood that in this implementation manner, the bracket has at least three connecting groups 4. With such a setting, the freedom degrees of the bracket in the N1 direction and the N2 direction in the folded state are limited, and the connection stability between the first support 2 and the second support 3 is higher in the folded state, which is beneficial to the bracket to maintain the folded state.

[0048] In some embodiments, asFigure 5 As shown, the outer contour of the first support 2 is set as a quadrilateral, and at least one first connecting member 23 is provided at each of the four corners of the first support 2. At least four first connecting members 23 provide a magnetic adsorption force at the edge of the first support 2. The lever arms between at least four first connecting members 23 are relatively large, generating a relatively large resultant force, reducing the possibility that the first support 2 separates from the second support 3 due to the corners being suspended.

[0049] In some embodiments, such as Figure 6 As shown, the outer contour of the second support 3 is set as a quadrilateral, and at least one set of second connecting members 33 is provided at each of the four corners of the second support 3. At least four second connecting members 33 provide a magnetic adsorption force at the edge of the second support 3. The lever arms between at least four second connecting members 33 are relatively large, generating a relatively large resultant force, reducing the possibility that the second support 3 separates from the first support 2 due to the corners being suspended.

[0050] Of course, in some possible implementation schemes, such as Figure 2 and Figure 7 As shown, the outer contours of both the first support 2 and the second support 3 can be set as quadrilaterals. Both the first support 2 and the second support 3 have four corners. In the folded state, at least one set of connection groups 4 is provided at each of the four corners, so that the four corners of the first support 2 are connected to the four corners of the second support 3 in a one-to-one correspondence. In this implementation manner, the bracket has at least four sets of connection groups 4.

[0051] In some embodiments, such as Figure 7 As shown, the bracket has four sets of connection groups 4. The two sets of connection groups 4 on the same side of the connecting arm 1 are arranged at intervals along the extending direction of the connecting arm 1, and the two sets of connection groups 4 adjacent to the same end of the connecting arm 1 are arranged at intervals along the direction perpendicular to the extending direction of the connecting arm 1. It can be understood that by connecting two adjacent sets of connection groups 4, the connecting line graph formed by the four sets of connection groups 4 is a rectangle, and one side of this rectangle is in the N1 direction. Such a setting maintains the stability of the bracket in the folded state with the least number of connection groups 4. The layout quantity of the connection groups 4 is small, reducing the assembly difficulty of each connection group 4 and also reducing the self-weight of the bracket, facilitating the bracket to stably adhere to the vertical surface of an object and also facilitating the user to carry.

[0052] In some embodiments, such as Figures 5-7As shown, the first magnetic member 22 and the second magnetic member 32 are arranged as magnetic rings. Each connecting group 4 is located outside the first magnetic member 22 and the second magnetic member 32. The first axis 221 is the central axis of the first magnetic member 22, and the second axis 321 is the central axis of the second magnetic member 32. That is to say, in the folded state, the orthographic projections of the first magnetic member 22 and the second magnetic member 32 in the thickness direction of the bracket are both approximately circular rings. With such a setting, the area covered by the first magnetic member 22 and the second magnetic member 32 is increased, so that the first magnetic member 22 and the second magnetic member 32 can provide magnetic adsorption force in a larger area, which is beneficial to maintaining the connection stability between the first support 2 and the second support 3 in the folded state; in addition, the first magnetic member 22 and the second magnetic member 32 are annular, and thus have a smaller self-weight, thereby reducing the self-weight load of the bracket, which is beneficial to maintaining the stability of the magnetic connection between the first support 2 and the electronic device, and is also beneficial to maintaining the stability of the magnetic connection between the second support 3 and the vertical support surface.

[0053] In some embodiments, as Figure 5 and Figure 6 shown, the connecting arm 1 has a symmetry axis 11. In the folded state, the symmetry axis 11 is perpendicular to the thickness direction of the bracket, and the first support 2 and the second support 3 are symmetrically arranged with respect to the symmetry axis 11 respectively. Referring to Figure 4 and Figure 7 , in the folded state, the first axis 221 and the second axis 321 are spaced apart in the extending direction of the connecting arm 1, and the first axis 221 and the second axis 321 are symmetrically arranged with respect to the symmetry axis 11. That is to say, in the N1 direction, the positions of the first magnetic member 22 and the second magnetic member 32 are symmetrically arranged with respect to the symmetry axis 11. Then in the N1 direction, the counterweight applied by the first magnetic member 22 to the position where the symmetry axis 11 is located is approximately equal to the counterweight applied by the second magnetic member 32 to the position where the symmetry axis 11 is located. The load of the bracket in the N1 direction is relatively uniform, reducing the possibility that the second support 3 separates from the support surface due to overweight.

[0054] In some embodiments, as Figure 1 shown, the connecting arm 1 includes a first connecting arm 1, a second connecting arm 1 and a third damping rotating shaft 14. The first support arm 12 is connected to the first support 2 through the first damping rotating shaft 21, the second support arm 13 is connected to the second support 3 through the second damping rotating shaft 31, and the third damping rotating shaft 14 is connected between the first support arm 12 and the second support arm 13. The first connecting arm 1 can rotate relative to the second connecting arm 1 and hover at any position through the third damping rotating shaft 14. With such a setting, while keeping the volume of the bracket unchanged, the rotation angle of the first support 2 and the movable space of the first support 2 are increased, making the bracket more flexible, the adjustable angle of the electronic device connected to the first support 2 larger, and capable of meeting the diverse needs of users.

[0055] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
