Description

Technical Field

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

[0002] In daily life, mobile phones have become indispensable devices. As an accessory for mobile phones, mobile phone stands, such as ring stands, can provide support for the phone. The ring stands contain magnets, which can be used to magnetically connect the back of the phone to other magnetic components when the ring stands are stored.

[0003] This type of ring-shaped bracket contains a magnet, which is covered by a Mylar sheet to achieve its magnetic attraction function. However, after a period of use, the magnetic attraction can cause the Mylar sheet to curl or lift up. This lifting can cause the internal magnet to fall off, weakening the magnetic attraction or even rendering the ring-shaped bracket nonexistent, thus reducing the user experience.

[0004] Therefore, in order to overcome at least some of the defects and deficiencies of the prior art, this utility model proposes a support structure.

[0005] On one hand, a bracket structure proposed in this embodiment of the present invention includes, for example, a support member; a connector embedded in the support member; and a magnetic absorbing member embedded in the support member, wherein the magnetic absorbing member and the connector are spaced apart; wherein the support member includes a strength layer; a support body connected to the strength layer, the support body and the strength layer being stacked and enclosing the magnetic absorbing member; the support body is provided with a connector clearance hole, a portion of the connector is enclosed by the support member, and another portion of the connector is exposed through the connector clearance hole.

[0006] In some embodiments, the support body is further provided with a mounting portion, which includes two mounting portions, each located at one end of the connector clearance hole. A portion of the connector is connected to the mounting portion and is covered by the strength layer.

[0007] In some embodiments, the connector includes a main body and two connecting portions disposed at both ends of the main body. One end of the strength layer is provided with an assembly portion, which corresponds to the connector clearance hole. The main body is disposed on the assembly portion and exposed through the connector clearance hole. The two connecting portions are respectively connected to the two mounting portions.

[0008] In some embodiments, the main body includes a base and a perimeter portion protruding from the base away from the strength layer, the perimeter portion separating the main body and the two connecting portions, the perimeter portion and the base portion together forming a hinge mounting groove.

[0009] In some embodiments, the bottom of the hinge mounting groove is further provided with a plurality of rivet posts, which are spaced apart and arranged along the length of the hinge mounting groove, and the plurality of rivet posts extend into the connector clearance hole.

[0010] In some embodiments, the side of the main body portion protrudes relative to the surrounding edge portion to form a protrusion portion, and the protrusion portion is provided to protrude outward from the outside of the main body portion. The inner sidewall of the connector clearance hole is recessed to form a groove portion, and the protrusion portion protrudes into the groove portion.

[0011] In some embodiments, the strength layer is located on the side of the connecting portion away from the mounting portion, the connecting portion is provided with a connecting through hole, and the mounting portion is provided with a protruding structure protruding toward the strength layer, the protruding structure filling the connecting through hole and being connected to the strength layer.

[0015] As can be seen from the above, the bracket structure provided by this utility model embodiment, by embedding a magnetic suction element in the support member and then covering the magnetic suction element with the support member, can cover and protect the magnetic suction element without Mylar sheet. At the same time, the connector and the magnetic suction element are located on the same layer of the strength layer, and some of the connectors are exposed through the connector avoidance holes on the support body, so that they can be connected to other structures, such as hinge structures, without affecting the connection of the bracket structure, making the overall structure of the bracket structure stronger, more durable, and improving the user's sense of use and experience.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The bracket structure in this embodiment is mainly used to connect to the back of the protective case of electronic devices, such as the back of a mobile phone case, and the connection between the mobile phone case and the bracket structure is realized through a hinge structure. Specifically, the connector 20 on the bracket structure 1 is connected to the hinge structure, thereby realizing the support and storage of the bracket structure.

[0030] In this embodiment, as Figures 1-3 As shown, the bracket structure 1 may include, for example, a support member 10, a connector 20, and a magnetic suction member 30.

[0031] The connector 20 is embedded in the support 10. The magnetic attractant 30 is embedded in the support 10 and is spaced apart from the connector 20.

[0032] The support member 10 includes, for example, a strength layer 11 and a support body 12. The support body 12 is connected to the strength layer 11 (e.g., by integral injection molding to form the support body 12 onto the strength layer 11, or by adhesive). The support body 12 overlaps with the strength layer 11 and encloses the magnetic suction member 30. The support body 12 has a connector clearance hole 121. A portion of the connector 20 is located between the strength layer 11 and the support body 12, while the other portion of the connector 20 is exposed through the connector clearance hole 121. Specifically, the strength layer 11 can serve as the basic structure of the support member 10, providing overall rigidity and shape stability to the bracket structure 1. The connector 20, located on the upper surface of the strength layer 11, can be used to fix external components, such as the lower cover of the bracket, ensuring precise alignment and structural stability, facilitating modular assembly; or it can be connected to a hinge to allow rotation of the support member 10. The connector 20 may be, for example, a protruding structure that mates with a hinge structure, such as multiple rivet posts. The magnetic component 30 may be directly mounted on the support body 12 of the support component 10, and may be, for example, an embedded magnetic element, such as an array of neodymium magnets, which can achieve strong magnetic attraction and automatic alignment, and can be used to support the rapid attraction of wireless charging devices and mobile phone cases, thereby charging mobile phones placed inside the cases. The support body 12 may be, for example, the outer layer of the bracket structure 1, which is formed by filling the entire bracket area with plastic material to form the outer layer structure. The support body 12 can provide insulation, cushioning, and surface sealing, while covering the inner layer, such as covering the magnetic component 30, to enhance integrity and stability. The support body 12 can be used to protect internal components and improve user safety. The strength layer 11 and the support body 12 are interlocked and stacked to form the main body of the bracket structure 1. Then, the support body 12 covers the magnetic 30 between the strength layer 11 and the support body 12, exposing a portion of the connector 20 to facilitate the connection of the connector 20 with the hinge structure to form a support accessory for the electronic device. The connector clearance hole 121 can be, for example, a clearance hole structure obtained by drilling holes in the support body 12. A portion of the connector 20 corresponds to the connector clearance hole 121; that is, a portion of the connector 20 is the part that connects to the hinge structure and must be exposed to connect and cooperate with the hinge structure. The remaining portion of the connector 20 is not exposed; that is, the remaining portion can be used as the part of the connector 20 to be fixedly connected to both the strength layer 11 and the support body 12, so that the connector 20 can be fixed between the strength layer 11 and the support body 12. By setting up a strength layer 11 and a support body 12, the materials of the strength layer 11 and the support body 12 can be different. The strength layer 11 is made of a harder material to achieve the overall strength of the support 10 and prevent the support 10 from bending or breaking during use.The support body 12 can be made of a material with relatively low hardness. On the one hand, this ensures that the support 10 is not too rigid and will affect the user experience. On the other hand, it can reduce the overall weight of the support 10 to a certain extent, which is more conducive to making the bracket structure or the protective case with the bracket structure thinner and easier to carry.

[0033] In this embodiment, a magnetic suction element 30 is embedded in the support member 10, and then the support member 10 covers the magnetic suction element 30, that is, the magnetic suction element 30 is covered between the strength layer 11 and the support body 12. This allows the magnetic suction element 30 to be covered and protected without Mylar sheet. At the same time, the connector 20 is set on the same side of the strength layer 11 as the magnetic suction element 30. Part of the connector 20 is exposed through the connector avoidance hole 121 on the support body 12, so that it can be connected to other structures, such as the hinge structure, without affecting the connection of the bracket structure 1. This makes the bracket structure 1 more robust and durable. The magnetic suction element 30 will not fall off during use, improving the user experience and extending the service life of the bracket structure 1.

[0034] Furthermore, such as Figure 3 As shown, the support body 12 is also provided with mounting portions 122. In this embodiment, there are two mounting portions 122, which are respectively located at both ends of the connector clearance hole 121. A portion of the connector 20 is connected to the mounting portion 122 and is covered by the strength layer 11. The mounting portion 122 can be, for example, a groove structure, which corresponds to the portion of the connector 20 wrapped in the strength layer 11 and the support body 12. In this embodiment, mounting portions 122 are provided at both ends of the connector clearance hole 121. The mounting portions 122 allow a portion of the connector 20 to be wrapped inside the support member 10, thereby increasing the connection strength between the connector 20 and the support member 10 and making it less likely for the connector 20 and the support member 10 to separate.

[0035] Furthermore, such as Figure 2As shown, one end of the strength layer 11 is provided with an assembly portion 111, which corresponds to the connector clearance hole 121. The connector 20 is located on the assembly portion 111. The assembly portion 111 is used to support the connector 20. In this embodiment, the strength layer 11 can be, for example, a ring-shaped structure, and the assembly portion 111 can be, for example, on any end of the ring structure. After the position of the assembly portion 111 is determined, a handle position can be provided on the other end of the strength layer opposite to the assembly portion 111. When the bracket structure is assembled to the back of the electronic device protective case, the user needs to pull the stored bracket structure out from the handle position and use the support function of the bracket structure. The connector 20 includes a main body 21 and two connecting portions 22 provided at both ends of the main body 21. The main body 21 is provided on the assembly portion 111 and exposed through the connector clearance hole 121. The two connecting portions 22 are respectively connected to the two mounting portions 122. The main body 21 can be, for example, the part that connects to external components. It mainly protrudes from the connector clearance hole 121 towards the upper side of the support body 12, facilitating the connection between the main body 21 and the external components. The connecting part 22 can be, for example, the part on the connector 20 that connects and is fixed to the strength layer 11 and the support body 12. By providing two connecting parts 22 at each end of the main body 21, the force borne by the connector 20 after connection with the external components is evenly distributed to the strength layer 11 and the support body 12, avoiding stress concentration that may occur with single-point fixing, and greatly improving the overall stability and fatigue resistance of the support structure. The main body 21 protrudes from the connector clearance hole 121, making the connection operation with external components more intuitive and easier to align, reducing assembly difficulty and improving the success rate and accuracy of the connection. The connecting parts 22 at both ends of the main body 21 extend between the strength layer 11 and the support body 12, ensuring that the connector 20 will not wobble or twist under stress, providing higher rigidity and stability to the support structure 1.

[0036] Furthermore, such as Figure 4 , Figure 5 and Figure 9 As shown, the main body 21 may include, for example, a base 211 and a perimeter 213 protruding from the base 211 away from the strength layer 11. The perimeter 213 separates the main body 21 from the two connecting parts 22. The perimeter 213 and the base 211 together form a hinge mounting groove. The base 211 may be, for example, a support plate, used as a base or substrate for load-bearing. The perimeter 213 may be, for example, a flange protruding from the base 211 and surrounding a portion of the edge of the base 211. The perimeter 213 can, on the one hand, strengthen the strength of the connector, and on the other hand, prevent liquid raw materials (e.g., colloids) forming the supporting body 12 from flowing into the hinge mounting groove during the overall injection molding of the bracket structure 1.

[0037] Furthermore, the bottom of the hinge mounting groove is provided with a plurality of rivet posts 212. These rivet posts 212 are spaced apart and arranged along the length of the hinge mounting groove, extending into the connector clearance hole 121. Since the rivet posts 212 are located within the hinge mounting groove, when the connector 20 is connected to an external component, such as a hinge assembly, via these rivet posts 212, the rivet posts 212 are all located within the hinge mounting groove. This means the height of the rivet posts 212 does not extend outside the hinge mounting groove. Consequently, when the connector 20 is connected to the lower cover of the bracket, the rivet posts within the hinge mounting groove will not abut against the outer side of the lower cover of the bracket. Therefore, no riveting marks will appear on the surface of the lower cover near the connector 20, meaning there are no riveting marks on the surface. This ensures that the overall aesthetics of the bracket formed after the bracket structure and the hinge assembly are connected are not affected.

[0038] Furthermore, such as Figures 4-7 As shown, the side of the main body 21 protrudes from the perimeter 213 to form a protrusion 23. After the connector clearance hole 121 is combined with the strength layer 11, the inner wall of the connector clearance hole 121 is recessed to form a groove 123, and the protrusion 23 protrudes into the groove 123 so that the connector 20 is embedded in the support member 10. The protrusion 23 can be, for example, a strip-shaped structure with the side of the perimeter 213 protruding towards the center of the support structure 1, or a strip-shaped structure with the outer surface of the inner side of the base 211 protruding towards the center of the support structure 1. Then, through the filling of the support body 12, another groove 123 is formed on the inner wall of the connector clearance hole 121. This groove 123 can be, for example, a groove structure, thereby further increasing the stability of the connection between the connector 20 and the strength layer 11 and the support body 12.

[0039] Furthermore, such as Figures 6-7 As shown, the strength layer 11 is located on the side of the connecting portion 22 away from the mounting portion 122, so that the connecting portion 22 is embedded in the support member 10. The connecting portion 22 includes a connecting through hole 221. The mounting portion 122 is provided with a protruding structure 124 protruding towards the strength layer 11. The protruding structure 124 fills the connecting through hole 221 and is connected to the strength layer 11. Since the support body 12 is formed by filling with injection-moldable plastic or photocurable material and curing it, the support body 12 will flow into the connecting through hole 221 during the filling process of injection-moldable plastic or photocurable material and come into contact with the surface of the strength layer 11. After curing, the protruding structure 124 is formed on the support body 12. The protruding structure 124 fills the connecting through hole 221 and is integrally formed with the strength layer 11, which can further increase the stability of the connection between the connector 20 and the strength layer 11 and the support body 12.

[0040] Furthermore, such as Figure 3 As shown, a magnetic suction cavity 125 is provided on the side of the support body 12 near the strength layer 11. The magnetic suction cavity 125 is spaced apart from the connector clearance hole 121, and the magnetic suction member 30 is disposed within the magnetic suction cavity 125. One end of the magnetic suction member 30 abuts against the bottom of the magnetic suction cavity 125, and the other end abuts against the strength layer 11. By providing the magnetic suction cavity 125, a unique and preset installation position and orientation are provided for the magnetic suction member 30, ensuring that the magnetic suction member 30 will not loosen, shift, or rotate during operation, thus maintaining the long-term stability and reliability of the magnetic suction member 30.

[0041] Furthermore, the magnetic attractor 30 includes a support portion 31 and a plurality of magnetic attracting portions 32. The support portion 31 is embedded in the support body 12 and together with the support body 12 forms the magnetic attractor receiving cavity 125. The plurality of magnetic attracting portions 32 are located within the magnetic attractor receiving cavity 125 and are disposed on the side of the support portion 31 facing the strength layer 11. Adjacent magnetic attracting portions 32 are separated by a partition. The support portion 31 may be, for example, a support plate, and may be injection molded from the support body 12, for example, by injection molding within the magnetic attractor receiving cavity 125. The magnetic attracting portions 32 may be, for example, embedded magnetic elements, such as arrayed neodymium magnets, which are compatible with wireless charger standards, achieving strong magnetic attraction and automatic alignment, thereby enabling the magnetic attractor 30 to support rapid adsorption of the bracket structure and wireless charging.

[0042] Furthermore, the strength layer 11 and the support body 12 are made of different materials, with the strength layer 11 having a higher hardness than the support body 12. The strength layer 11 and the support body 12 can be, for example, non-metallic material layers. Specifically, the strength layer 11 is a non-metallic strength layer, and the support body 12 is a non-metallic insulating and sealing material layer. The strength layer 11 can be, for example, a layer made of a high-strength thin non-metallic material, such as carbon fiber composite material. The support body 12 is a layer made of injection-molded plastic material or photocurable material. The support body 12 can be formed by injection molding or filling the strength layer 11 after the support structure 1 is first assembled with the strength layer 11, the connector 20, and the magnetic 30, thereby forming the outer layer of the support structure 1 and simultaneously sealing the magnetic 30. In this embodiment, the connector 20 may be made of metal, for example. The connector 20 is made of metal because it needs to be connected to the hinge structure, which is made of metal. Furthermore, the hinge structure needs to be riveted or welded to the connector. If the connector is made of non-metallic material, it cannot be welded or riveted to the hinge structure. By making the connector a metal part, the connection strength and stability at the connection point can be guaranteed. Because existing bracket structures require strength and easy hinge connection, bracket structure 1 is typically made of metal and can be installed, for example, on the back of a phone case. However, with increasing numbers of phones featuring wireless charging, when using such a bracket structure for wireless charging, the bracket's installation position overlaps with the wireless charging location. Furthermore, wireless charging is inductive, and the metal bracket can affect the magnetic field, impacting charging efficiency. Additionally, charging can cause the metal bracket to overheat, triggering charging protection and further reducing efficiency. Therefore, this embodiment uses non-metallic materials for the strength layer 11 and the support body 12, while the connector 20 is made of metal to secure external components (such as the bracket's lower cover), ensuring precise alignment and structural stability. This facilitates modular assembly.

[0043] Furthermore, such as Figure 8 and Figure 10 As shown, the distance between the edge of the connector 20 near the magnetic member 30 and the edge of the magnetic member 30 near the connector 20 is 0.5-3 mm; and / or, the thickness of the strength layer 11 does not exceed 0.5 mm. Figure 8 As shown, the distance between the left edge of the connector 20 and the left edge of the magnetic accumulator 30 is d1, and the width of d1 is 0.5-3.0 mm. By leaving enough space for adhesive to adhere to d1 (0.5-3.0 mm), the width of the connecting portion 22 in the connector 20 can be increased, thereby enhancing the structural strength of the connector 20. Figure 9As shown, when the thickness of the strength layer h1 ≤ 0.5mm, it not only provides strong support for the bracket structure 1, but also allows the magnetic part 32 in the magnetic component 30 to be closer to the adsorption surface. This results in the magnet providing stronger attraction when using the same specification magnet, making it more convenient for users and improving the user experience.

[0044] Furthermore, it is understood that the foregoing embodiments are merely illustrative examples of this utility model. Provided that the technical features do not conflict, the structure is not contradictory, and the inventive purpose of this utility model is not violated, the technical solutions of the various embodiments can be arbitrarily combined and used.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not 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.
