Description

Technical Field

[0001] This utility model relates to the field of digital accessories, and in particular to a bracket structure. Background Technology

[0002] In daily life, people frequently use digital products such as mobile phones and tablets for watching videos and taking photos. For ease of use, people usually use stands to position their phones and tablets at a fixed angle. Stands come in many forms, among which the support bracket is a widely used type.

[0003] Existing support brackets typically have two degrees of rotational freedom, allowing them to rotate on the back of the phone. The bracket's angle can also be adjusted for flexible support options. Since the support bracket needs to rotate, but uncontrolled rotation during use is undesirable, a structural balance between rotation and positioning is required. This ensures smooth rotation while maintaining a stable position after rotation. Current support brackets usually achieve positioning using elastic structures (such as springs and spring sheets). However, these elastic structures have a limited lifespan and are prone to fatigue failure after repeated rotation, leading to reduced rotation efficiency or malfunction. Therefore, further improvements are needed. Utility Model Content

[0004] The present invention aims to solve the above problems by providing a support structure that achieves positioning through magnetic action.

[0005] To solve the above problems, this utility model provides a support structure, characterized in that it includes:

[0006] Fixed body

[0007] A movable component is rotatably connected to the fixed body, and the movable component can rotate about a first rotation center;

[0008] A support member is rotatably connected to the movable member. The support member can rotate relative to the movable member about a second rotation center to adjust the operating angle, and can rotate together with the movable member about a first rotation center.

[0009] A magnetic positioning component is disposed between the fixed body and the movable part, and is used to achieve relative positioning of the movable part and the fixed body through magnetic force when the movable part rotates relative to the fixed body, so that the movable part maintains its current position.

[0010] Furthermore, the magnetic positioning component includes a positioning element, a first magnetic element, and a second magnetic element arranged along a first direction. The first magnetic element is movably disposed between the positioning element and the second magnetic element. The first magnetic element and the second magnetic element repel each other magnetically, thereby driving the positioning element to constantly abut against the movable element for positioning.

[0011] Furthermore, a plurality of positioning grooves are provided on the wall portion of the movable member facing the fixed body, and the positioning member is at least partially located in one of the positioning grooves. The positioning member can slide from the current positioning groove to another positioning groove when the movable member rotates relative to the fixed body.

[0012] Furthermore, the positioning grooves are evenly spaced along the circumference around the first rotation center, and the positioning element is a spherical ball.

[0013] Furthermore, the first direction is perpendicular to the first rotation center and the second rotation center, or the first direction is parallel to the first rotation center and perpendicular to the second rotation center.

[0014] Furthermore, the fixed body is provided with a first receiving groove and a second receiving groove arranged along the first direction, the first receiving groove communicating with the positioning groove; the first magnetic element is movably disposed in the first receiving groove, and the second magnetic element is disposed in the second receiving groove; the positioning element is at least partially located in the first receiving groove; the second magnetic element and the first magnetic element are magnetically repelled, causing the first magnetic element to approach the positioning element.

[0015] Furthermore, the first receiving groove includes a first groove portion and a second groove portion, the first groove portion passing through the positioning groove and the second groove portion, and the size of the first groove portion is smaller than the size of the second groove portion in the direction transverse to the first direction, the positioning member is at least partially located in the first groove portion, and the first magnetic member is movably disposed in the second groove portion and can move in the second groove portion along the first direction.

[0016] Furthermore, one or more clearance grooves are provided on the outside of the second groove and the second receiving groove, and the clearance grooves are respectively connected to the second groove and the second receiving groove.

[0017] Furthermore, the fixing body includes:

[0018] A fixing seat, wherein a protruding flange is provided on the outer circumferential wall of the fixing seat;

[0019] A pressure cap is connected to one end of the fixing base and protrudes from the outer edge of the fixing base, with the edge of the pressure cap being spaced apart from the protruding edge;

[0020] The movable component is fitted onto the fixed base and is at least partially located between the protruding edge and the edge of the pressure cap; the movable component is rotatable around the fixed base.

[0021] Furthermore, a storage groove is provided on the side of the movable component facing the support component. The support component can rotate around the second rotation center to enter the storage groove and fit against the movable component. The support component can also rotate around the second rotation center to form an angle with the movable component for support. Magnetic rings for magnetic adsorption are provided on the support component and / or the movable component and / or the fixed base and / or the pressure cover. The magnetic rings are closed-loop or have notches.

[0022] The beneficial contribution of this utility model lies in its effective solution to the aforementioned problems. The bracket structure of this utility model provides a novel positioning structure that eliminates the need for elastic elements. Instead, positioning is achieved by using magnetic repulsion to drive the positioning element to move adaptively, resulting in a highly innovative structure. Since the magnetic repulsion works in the air and the magnet has no lifespan issue, repeated rotation will not lead to a deterioration in rotational performance or malfunction, significantly improving usability. The bracket structure of this application is novel and highly practical, and should be widely promoted. It can be used not only as a standalone bracket but also integrated into protective shells, making its application scope very broad. Attached Figure Description

[0044] The following embodiments are further explanations and supplements to the present invention and do not constitute any limitation on the present invention.

[0045] like Figures 1 to 12 As shown, the support structure of this utility model includes a fixed body 10, a movable part 20, a support part 30, and a magnetic positioning component 40. Compared with the prior art, its main invention lies in the positioning between the relatively rotating fixed body 10 and the movable part 20 through the magnetic positioning component 40, so that the movable part 20 remains in the current position and does not rotate arbitrarily.

[0046] The fixing body 10 is a component that does not move relative to the mobile phone, tablet, or other digital product during use. It can be a separate component or integrated into the protective case 70 to become part of the protective case 70. The fixing body 10 can be a hollow ring or a solid column, depending on the specific needs.

[0047] like Figure 1 , Figure 2 As shown, the movable component 20 is rotatably connected to the fixed body 10, and the movable component 20 can rotate about the first rotation center L1. The first rotation center L1 is the normal of the screen (such as a mobile phone screen, tablet screen, etc.) and also the axis of the fixed body 10.

[0048] like Figure 1 , Figure 2 As shown, the support member 30 is rotatably connected to the movable member 20. The support member 30 can rotate relative to the movable member 20 around a second rotation center L2, and can also rotate with the movable member 20 around a first rotation center L1. The second rotation center L2 has a different direction than the first rotation center L1. The second rotation center L2 is parallel to the screen. The support member 30 can rotate relative to the movable member 20, and when the movable member 20 rotates, the support member 30 can rotate with it. Thus, the support member 30 has two degrees of rotational freedom, allowing the user to freely adjust the support position and angle to meet various support needs.

[0049] The magnetic positioning component 40 is disposed between the fixed body 10 and the movable component 20. It is used to achieve relative positioning of the movable component 20 and the fixed body 10 through magnetic force when the movable component 20 rotates relative to the fixed body 10. This ensures that the movable component 20 remains stationary relative to the fixed body 10 when no external force is applied, and does not rotate arbitrarily. Relative positioning means that the movable component 20 and the fixed body 10 maintain their current relative positional relationship without actively changing their positional relationship, i.e., without arbitrarily rotating.

[0050] Furthermore, such as Figure 1 , Figure 5 , Figure 8 As shown, the magnetic positioning assembly 40 includes a positioning element 41, a first magnetic element 42, and a second magnetic element 43 disposed along a first direction L3. The first magnetic element 42 is movably disposed between the positioning element 41 and the second magnetic element 43. The first magnetic element 42 and the second magnetic element 43 repel each other magnetically, thereby driving the positioning element 41 to constantly abut against the movable element 20 for positioning.

[0051] Because the first magnetic element 42 and the second magnetic element 43 are magnetically repulsive, under the action of magnetic repulsion, the first magnetic element 42 will move away from the second magnetic element 43 and closer to the positioning element 41, thereby applying a force to the positioning element 41. This causes the positioning element 42 to abut against the movable element 20, restricting the movable element 20 and preventing it from rotating freely without external force. When the force applied to the movable element 20 can overcome the magnetic repulsion, the movable element 20 presses against the positioning element 41, causing the positioning element 41 and the first magnetic element 42 to move between the second magnetic element 43 and the movable element 20 to accommodate the rotation of the movable element 20. During this process, under the action of magnetic repulsion, the positioning element 41 always abuts against the corresponding surface of the movable element 20. When the rotation of the movable part 20 stops and the external force is lost, the positioning part 41 abuts against the movable part 20 under the action of magnetic repulsion, so that the magnetic positioning component 40 and the movable part 20 are both stationary relative to the fixed body 10 and maintain their current relative position relationship, thus preventing the movable part 20 from rotating freely.

[0052] Furthermore, such as Figure 4 , Figure 8 As shown, a plurality of positioning grooves 21 are provided on the wall portion of the movable member 20 facing the fixed body 10. The positioning member 41 is partially located in one of the positioning grooves 21. The positioning member 41 can slide from the current positioning groove 21 to another positioning groove 21 when the movable member 20 rotates relative to the fixed body 10.

[0053] When the positioning member 41 is partially located in the positioning groove 21, it can lock the movable member 20 without external force, so that the movable member 20 cannot rotate freely relative to the fixed body 10.

[0054] When the movable part 20 rotates, the positioning grooves 21 at different positions on the movable part 20 will correspond one by one with the positioning part 41, so that the positioning part 41 can enter from one positioning groove 21 to another positioning groove 21.

[0055] The positioning grooves 21 are evenly spaced along the circumference surrounding the first rotation center L1.

[0056] In some embodiments, such as Figure 4 , Figure 5 As shown, the movable component 20 is annular, and the positioning groove 21 can be disposed on the inner circumference of the movable component 20, facing the outer circumference of the fixed body 10. In this embodiment, the first direction L3 is perpendicular to the first rotation center L1 and the second rotation center L2. The first direction L3 is the radial direction of the movable component 20 and the fixed body 10.

[0057] In some embodiments, such as Figure 8As shown, the movable component 20 is disc-shaped or has a disc-shaped portion, and the positioning groove 21 can be disposed on the disc end face of the movable component 20, facing the end face of the fixed body 10. Here, the end face refers to the end surface perpendicular to the first rotation center L1. In this embodiment, the first direction L3 is parallel to the first rotation center L1 and perpendicular to the second rotation center L2. The first direction L3 is the axial direction of the movable component 20 and the fixed body 10.

[0058] The shape of the positioning groove 21 can be set as needed, and it is formed by a concave surface. In some embodiments, the positioning groove 21 can be set as a semi-cylindrical groove. In some embodiments, the positioning groove 21 can be set as a hemispherical groove. Of course, the shape of the positioning groove 21 is not limited. To facilitate smoother rotation, the positioning groove 21 should be set to have an arc-shaped surface, so as to facilitate the positioning member 41 to slide from one positioning groove 21 into another positioning groove 21.

[0059] The shape of the positioning member 41 can be set as needed. It can be a strip, a block, or a ball. It can be partially inserted into the positioning groove 21 to restrict the movable member 20, so that the movable member 20 cannot rotate freely.

[0060] In this embodiment, the positioning groove 21 is a semi-cylindrical groove, which is evenly distributed on the inner circumference of the movable part 20, and the positioning groove 21 itself extends along the axial direction of the movable part 20.

[0061] In other implementations, the positioning groove 21 is a hemispherical groove, which is evenly distributed on the end face of the movable part perpendicular to the first rotation center L1.

[0062] The positioning element 41 is a steel ball, which partially abuts against the positioning groove 21. The positioning element 41 can not only restrict the free rotation of the moving part 20, but also produce a rhythmic impact sound when the positioning element 41 slides from one positioning groove 21 into another positioning groove 21, thus creating a sound. This not only makes it easier for the user to perceive the rotation, but also enhances the user experience.

[0063] This magnetic positioning component 40 not only enables stepless rotational positioning but also produces a sound, thus greatly improving the user experience.

[0064] Furthermore, such as Figure 4 , Figure 6As shown, to facilitate the placement of the first magnetic component 42 and the second magnetic component 43, a first receiving groove 11 and a second receiving groove 12 are provided on the fixing body 10. The first receiving groove 11 and the second receiving groove 12 are arranged along a first direction L3. The first receiving groove 11 communicates with the positioning groove 21. The second receiving groove 12 may or may not communicate with the first receiving groove 11. The first magnetic component 42 is movably disposed in the first receiving groove 11, and the second magnetic component 43 is disposed in the second receiving groove 12.

[0065] The positioning element 41 is at least partially disposed in the first receiving groove 11 and can contact the first magnetic element 42. The second magnetic element 43 and the first magnetic element 42 are magnetically repelled, which causes the first magnetic element 42 to be located at the end closer to the positioning element 41.

[0066] The size of the first receiving groove 11 in the first direction L3 should be larger than the size of the first magnetic element 42, so that the first magnetic element 42 can move in the first direction L3 to adapt to the magnetic repulsion force and the rotation of the moving element 20.

[0067] When the movable part 20 rotates, it presses against the positioning part 41. When the positioning groove 21 aligns with the positioning part 41, the positioning part 41 is partially engaged in the positioning groove 21 under the magnetic repulsion of the first magnetic element 42 and the second magnetic element 43. When the movable part 20 rotates until the positioning groove 21 and the positioning part 41 are misaligned, the positioning part 41 slides out of the positioning groove 21 and is squeezed into the first receiving groove 11. At this time, the first magnetic element 42 is forced to move closer to the second magnetic element 43. When the movable part 20 rotates until the positioning groove 21 aligns with the positioning part 41 again, the second magnetic element 43 pushes the first magnetic element 42 through magnetic repulsion, thereby pushing the positioning part 41 to move towards the positioning groove 21 and re-engage in the positioning groove 21. In this way, the movable part 20 can be rotated infinitely. When the rotation stops, the positioning part 41 will be locked into the positioning groove 21 to restrict the movable part 20, so that the movable part 20 can maintain its current position and no longer rotate freely, thereby achieving positioning after rotation.

[0068] During the entire rotation process, the positioning element 41 may be entirely located in the first receiving groove 11, or it may be partially located in the positioning groove 21. The positioning element 41 cannot be entirely located in the positioning groove 21, because in this case, the positioning element 41 would lose its positioning function and would not be able to lock the moving part 20.

[0069] Furthermore, such as Figure 4 , Figure 6As shown, the first receiving groove 11 includes a first groove portion 111 and a second groove portion 112. The first groove portion 111 is used to house the positioning member 41, and the second groove portion 112 is used to house the first magnetic member 42. The first groove portion 111 extends through the positioning groove 21 and the second groove portion 112, and the size of the first groove portion 111 in the direction transverse to the first direction L3 is smaller than the size of the second groove portion 112. This allows the first magnetic member 42 to act on the positioning member 41 and provides a stroke constraint on the positioning member 41, limiting its range of motion.

[0070] Furthermore, the dimension of the second groove 112 in the first direction L3 is larger than the dimension of the first magnetic element 42, thereby allowing the first magnetic element 42 to move within the second groove 112 along the first direction L3.

[0071] Furthermore, the dimension of the second groove 112 in the transverse direction L3 is equivalent to the dimension of the first magnetic element 42, which can serve as a movement limit, restricting the first magnetic element 42 to move only along the first direction L3.

[0072] In order to ensure that the magnetic repulsion force mainly acts in the first direction L3, the first magnetic element 42 and the second magnetic element 43 are preferably rectangular block magnets.

[0073] The second groove 112 may or may not be continuous with the second receiving groove 12 in the first direction L3. The dimensions of the second groove 112 may be the same as or different from those of the second receiving groove 12. When the second groove 112 is continuous with the second receiving groove 12, the first receiving groove 11 and the second receiving groove 12 appear as a single slot in terms of their physical structure. When the second groove 112 is not continuous with the second receiving groove 12, the first receiving groove 11 and the second receiving groove 12 appear as two independent slots in terms of their physical structure.

[0074] Therefore, it should be noted that the first receiving groove 11 and the second receiving groove 12 described in this application are divided by function. In terms of physical structure, they may be one slot or two slots.

[0075] Preferably, the second groove 112 and the second receiving groove 12 do not communicate with each other in the first direction L3, and the two are isolated from each other.

[0076] Furthermore, one or more clearance grooves 13 are provided around the second groove 112 and the second receiving groove 12, respectively. The clearance grooves 13 are respectively connected to the second groove 112 and the second receiving groove 12, which can facilitate the installation of the first magnetic component 42 and the second magnetic component 43.

[0077] When the movable component 20 rotates around the fixed body 10, the walls on which they rotate relative to each other can be parallel to the first rotation center L1 (e.g., Figure 4 , Figure 5 As shown), it can also be perpendicular to the first rotation center L1 (as shown). Figure 8 (As shown). Accordingly, the connection structure between the movable part 20 and the fixed body 10 is slightly different. In this embodiment, as shown... Figure 4 , Figure 5 As shown, the preferred wall surfaces of the movable part 20 and the fixed body 10 that rotate relative to each other are parallel to the first rotation center L1. Therefore, the description is mainly based on this structure.

[0078] In this embodiment, the fixing body 10 includes a fixing base 14 and a pressure cover 15. The fixing base 14 and the pressure cover 15 are independent components.

[0079] The fixing base 14 can be a hollow ring (e.g., Figures 1 to 9 , Figure 11 (As shown), it can also be a solid column (such as...) Figure 10 , Figure 12 As shown in the figure, the specific configuration can be adjusted according to needs. In this embodiment, the fixing base 14 is preferably configured as a hollow ring.

[0080] like Figure 5 As shown, a protruding flange 141 is provided on the outer circumferential wall of the fixed base 14.

[0081] The pressure cap 15 is connected to the end of the fixed base 14 and protrudes from the outer edge of the fixed base 14. The edge of the pressure cap 15 is spaced apart from the protruding edge 141 to form a limiting space for rotating the movable part 20.

[0082] The movable member 20 is annular and is sleeved on the fixed base 14 and is at least partially located between the edge of the protruding edge 141 and the edge of the pressure cap 15. In this way, the movable member 20 can rotate around the fixed base 14 and is restricted between the protruding edge 141 and the pressure cap 15 without coming out.

[0083] Furthermore, the first receiving groove 11 and the second receiving groove 12 are provided on the fixing base 14, and are recessed relative to the surface of the fixing base 14. When the pressure cap 15 is connected to the end of the fixing base 14, it can cover the first receiving groove 11 and the second receiving groove 12, so that the first magnetic element 42 and the second magnetic element 43 are enclosed in the fixing body 10.

[0084] Furthermore, in some embodiments, such as Figures 2 to 4As shown, to balance aesthetics and functionality, the mounting base 14 includes an annular main body 142 and a protruding extension 143. The extension 143 is located inside the main body 142 and is used to provide the second receiving groove 12. The first receiving groove 11 is provided on the main body 142. Correspondingly, the shape of the pressure cap 15 matches the shape of the mounting base 14, and it can cover the first receiving groove 11 and the second receiving groove 12. Of course, the pressure cap 15 can be set as a single integral pressure cap 15, or it can be set as two separate pressure caps 15, one matching the main body 142 to cover the first receiving groove 11, and the other for separately covering the second receiving groove 12.

[0085] Furthermore, the movable component 20 and the support component 30 are rotatably connected by a hinge structure 50.

[0086] The hinge structure 50 includes a first hinge 51 and a second hinge 52. The first hinge 51 has a first pivot portion, and the second hinge 52 has a second pivot portion. The first pivot portion and the second pivot portion are connected together by a pivot, so the first hinge 51 and the second hinge 52 can rotate relative to each other. The central axis of the pivot is the second rotation center L2.

[0087] The first hinge 51 is fixedly connected to the movable member 20, and the second hinge 52 is fixedly connected to the support member 30. Thus, the support member 30 can rotate relative to the movable member 20 around the second rotation center L2, and simultaneously, the support member 30 and the movable member 20 can rotate together around the first rotation center L1.

[0088] Furthermore, in some embodiments, a receiving groove 22 is provided on the side of the movable member 20 facing the support member 30, and the shape of the receiving groove 22 matches the shape of the support member 30. When the support member 30 rotates around the second rotation center L2, it can rotate into the receiving groove 22 to fit against the movable member 20, and can rotate to form an angle with the movable member 20 for support. The usage angle can be adjusted by adjusting the rotation angle of the support member 30.

[0089] To ensure that the support 30 can maintain its current angle, a damping component can be provided on the pivot.

[0090] Furthermore, to facilitate magnetic charging, a magnetic ring for magnetic attraction is provided in any one or more of the support member 30, the movable member 20, the fixed base 14, and the pressure cover 15. The magnetic ring can be closed-loop or have a notch, and its shape can be adaptively adjusted according to its placement.

[0091] This application does not limit the placement of the magnetic ring; it can be set as needed.

[0092] Furthermore, to enhance aesthetics and overall appearance, the end face of the fixed body 10 is flush with the end face of the movable part 20.

[0093] Furthermore, such as Figure 3 As shown, to facilitate user adjustment of the support member 30, a clearance space 60 is formed between the support member 30 and the movable member 20, which is used to insert a finger to lift the support member 30 and adjust the angle of the support member 30.

[0094] Furthermore, in other embodiments, such as Figure 8 As shown, when the wall surface of the movable component 20 rotating relative to the fixed body 10 is perpendicular to the first rotation center L1, the first direction L3 is parallel to the first rotation center L1. At this time, the aforementioned structure can be adaptively adjusted. The main structures that need adjustment are as follows: Figure 8 As shown, the fixed body 10 may not need to be equipped with a pressure cover 15. The movable part 20 is provided with a pressure cover portion 23 on the end face of the fixed body 10. In this case, the positioning groove 21 is provided on the pressure cover portion 23.

[0095] The support structure described in this application can be used as an independent support (e.g., Figures 1 to 8 (As shown), it can also be integrated into the protective shell 70 as part of the structure of the protective shell 70 (e.g. Figures 9 to 12 (As shown).

[0096] like Figures 1 to 8 As shown, when the bracket structure is used as an independent bracket, adhesive can be provided on the side surface (end face) of the fixed body 10 opposite to the support member 30, which can be directly pasted onto the protective case 70 or the back of the mobile phone for use.

[0097] When the bracket structure is integrated on the protective shell 70, the bracket structure can protrude from the surface of the protective shell 70, or a mounting groove can be provided on the protective shell 70 to embed the bracket structure in the mounting groove.

[0098] like Figure 9 , Figure 10 As shown, when the support structure protrudes from the surface of the protective shell 70, the fixing body 10 can be fixedly connected to the back of the protective shell 70 or integrally formed. The fixing body 10 can be a ring-shaped structure or a column-shaped structure.

[0099] like Figure 11 , Figure 12 As shown, when the bracket structure is embedded in the mounting groove of the protective shell 70, the fixing body 10 is fixedly connected to or integrally formed with the protective shell 70, and protrudes from the mounting groove. The fixing body 10 can be a ring-shaped structure or a column-shaped structure.

[0100] Although the present invention has been disclosed through the above embodiments, the scope of the present invention is not limited thereto. Without departing from the concept of the present invention, the above components can be replaced by similar or equivalent elements known to those skilled in the art.
