Description

Technical Field

[0001] This utility model relates to the field of photographic equipment technology, and in particular to a multifunctional mobile phone fixing device. Background Technology

[0002] Selfie sticks are a globally popular selfie accessory. They can extend and retract within a certain length range. Users simply attach their shooting device, such as a phone or camera, to the extension rod and then take selfies from multiple angles using a remote control or the shutter button on the selfie stick. Traditional selfie sticks typically include at least an extension rod and a phone holder. One end of the extension rod is connected to the phone holder, while the other end is held in the hand. Existing phone holders usually include a clip body and a handle assembly. The clip body includes a fixed clamp and a movable clamp positioned above the fixed clamp. The movable clamp and the fixed clamp form a clamping space for holding the phone. The upper end of the handle assembly is rotatably connected to the fixed clamp, allowing the clip body to position the mobile device horizontally, vertically, or at any angle between horizontal and vertical.

[0003] To expand the functionality of mobile phone mounting devices, magnetic components have been introduced in existing technologies, further increasing the methods or scope of device mounting through magnetic attraction. However, current magnetic component designs have the following problems:

[0004] 1. The magnetic attachment is located on the back of the clamping component. In this design, the magnetic attachment and the clamping component are independent and cannot be used simultaneously. This structure results in limited functionality during use, and the overall size of the phone holder after folding is relatively large and the appearance is not refined, affecting not only portability but also the product's aesthetics.

[0005] 2. The magnetic suction component is located inside the clamping component. In this design, the magnetic suction component is embedded within the phone holder. When the phone holder is used to clamp the device, the clamping component folds inside the magnetic suction component. Because storage space needs to be reserved for the clamping part, the magnet of the magnetic suction component cannot be designed as a single piece but must be assembled in segments. This structure not only increases the manufacturing complexity of the magnets, requiring separate molds and multi-segment magnetization, leading to a significant increase in production costs, but may also reduce magnetic strength and lifespan. Utility Model Content

[0006] Therefore, it is necessary to address the issues that still need improvement in terms of structure, size, aesthetics, and manufacturing cost when integrating magnetic components into existing mobile phone fixing devices. A multifunctional mobile phone fixing device should be provided to reduce production costs and improve magnetic strength and reliability.

Then, the second clamping member rotates about the fourth axis until the inner side of the second clamping portion is in contact with the back side of the outer shell.

[0015] In one embodiment, the first clamping assembly further includes a first positioning structure disposed between the first movable member and the first fixed member, for limiting the rotational position of the first movable member relative to the first fixed member; the second clamping assembly further includes a second positioning structure disposed between the second movable member and the second fixed member, for limiting the rotational position of the second movable member relative to the second fixed member.

The first reinforcing portion, the second reinforcing portion and the second outer shell form a second storage groove at the other end along the first direction, and the second movable member is located in the first storage groove.

[0023] The aforementioned multi-functional mobile phone holder allows the first and second clamping parts to fit snugly against the back of the casing after folding, without interfering with the independent use of the magnetic attraction function.

[0049] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described clearly and completely below with reference to the accompanying drawings. Obviously, the specific details described below are only a part of the embodiments of this utility model, and this utility model can be implemented in many other embodiments different from those described herein. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0050] In this document, when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The directional terms such as "front," "back," "up," and "down" are defined based on the location of the components in the accompanying drawings and their relative positions, and are merely for clarity and convenience in expressing the technical solution. It should be understood that the use of these directional terms should not limit the scope of protection claimed by this utility model.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0052] like Figure 1-4 As shown, in one embodiment of this utility model, the multifunctional photography bracket includes: a telescopic rod 2, a mobile phone fixing device 1, and a handle assembly 3. The telescopic rod 2 is composed of multiple tubes of different diameters nested together from largest to smallest. For ease of description, the tube section furthest when the telescopic rod 2 is extended is defined as the distal tube 22, and the tube section closest when extended is defined as the proximal tube (not shown in the figure). Preferably, to facilitate the installation of the mobile phone fixing device 1, a support 21 is fixedly fitted to the top of the distal tube 22 for mounting the mobile phone fixing device 1.

[0053] The handle assembly 3 includes a mounting base assembly 31 and at least three support plates 32. The mounting base assembly 31 is sleeved on the distal tube 22, and the mounting base assembly 31 and the distal tube 22 can be either slidably connected or fixedly connected. One end of each of the at least three support plates 32 is pivotally connected to the mounting base assembly 31. When unfolded, the support plates 32 form a stable tripod structure; when folded, the support plates 32 fit snugly against the surface of the distal tube 22, facilitating carrying and storage.

[0054] like Figure 6 , 7The mobile phone fixing device 1 includes a support member 11, a housing 12, a magnetic adsorption element 13, a first clamping assembly 14, a first telescopic assembly 15, a second clamping assembly 16, and a second telescopic assembly 17. The support member 11 is strip-shaped, having a first end 111 and a second end 112 along its length. The first end 111 of the support member 11 is rotatably connected to a support 21, and the second end 112 of the support member 11 is connected to the housing 12. As an example, the support 21 is provided with a connector 211, and the first end 111 of the support member 11 is provided with an inverted U-shaped groove 111a. The connector 211 is rotatably mounted in the inverted U-shaped groove 111a via a connecting shaft 18, allowing for angle adjustment of the support member 11. Preferably, the first end 111 of the support member 11 has a curved portion 113 that bends towards its rear side, and the curved portion 113 is provided with the inverted U-shaped groove 111a. In this way, when the support member 11 is folded up, it can ensure that the mobile phone fixing device 1 and the handle assembly 3 fit together, reducing the volume after folding.

[0055] The housing 12 is mounted on the second end 112 of the support 11, and the housing 12 has a first direction (i.e. Figure 6 The first end 111 and the second end 112 in the X direction, as well as the front and back sides located on both sides of the first direction.

[0056] A magnetic adsorption element 13 is disposed inside the housing 12 and is used to form an annular positioning magnetic adsorption area on the front side of the housing 12 for adsorbing the mobile phone.

[0057] The first clamping component 14 is disposed at the first end 111 of the outer shell 12 and is connected to the outer shell 12 through the first telescopic component 15. The first clamping component 14 includes a first clamping part 143a, which is movable between the working position and the folded position.

[0058] The second clamping assembly 16 is disposed at the second end 112 of the housing 12 and is connected to the housing 12 via the second telescopic assembly 17. The second clamping assembly 16 includes a second clamping part 163a, which is movable between the working position and the folded position.

[0059] When both the first clamping part 143a and the second clamping part 163a are in the working position, the inner side of the first clamping part 143a and the inner side of the second clamping part 163a together with the front of the outer shell 12 form a clamping space for clamping the mobile phone; when both the first clamping part 143a and the second clamping part 163a are in the folded position, the inner side of the first clamping part 143a and the second clamping part 163a are in contact with the back of the outer shell 12; when the support member 11 is folded, the outer side of the first clamping part 143a and the second clamping part 163a can be in contact with the surface of the handle assembly 3.

[0060] The mobile phone fixing device 1 of this application achieves the following technical effects through the optimized combination design of the clamping component and the magnetic component:

[0061] 1. The clamping component and the magnetic suction component are designed as an integrated structure. The magnetic suction component can be used independently for adsorption devices or in conjunction with the clamping component, avoiding the problem of the two functions being independent in the prior art, and improving the product's versatility and applicability.

[0062] 2. When folded, the clamping component fits snugly against the back of the outer casing 12, without interfering with the independent use of the magnetic attraction function, eliminating the need to reserve storage space for the clamping component on the front of the outer casing 12. This design allows the magnetic attraction element 13 to adopt an integrated structural design, avoiding the design complexity of traditional segmented magnets, simplifying the manufacturing process, reducing the cost of separate mold opening and multi-segment magnetization, not only reducing production costs but also improving magnetic strength and reliability, further extending the product's service life.

[0063] See Figure 5-11 In one embodiment, the first clamping assembly 14 includes a first fixing member 141, a first movable member 142, and a first clamping member 143. The first fixing member 141 is connected to the outer shell 12 via the first telescopic assembly 15. The first movable member 142 is connected to the first fixing member 141 and is rotatable about a first axis A1 parallel to the first direction. The first clamping member 143 is connected to the first movable member 142 and is rotatable about a second axis A2 perpendicular to the first direction. The first clamping member 143 is provided with a first clamping portion 143a. When folded, the first movable member 142 rotates about the first axis A1, causing the first clamping member 143 to move together, so that the first clamping portion 143a rotates from the front side to the back side of the outer shell 12. Then, the first clamping member 143 rotates about the second axis A2 until the inner side of the first clamping portion 143a is in contact with the back side of the outer shell 12.

[0064] Similarly, the second clamping assembly 16 includes a second fixing member 161, a second movable member 162, and a second clamping member 163. The second fixing member 161 is connected to the outer shell 12 via the second telescopic assembly 17. The second movable member 162 is connected to the second fixing member 161 and is rotatable about a third axis A3 parallel to the first direction. The second clamping member 163 is connected to the second movable member 162 and is rotatable about a fourth axis A4 perpendicular to the first direction. The second clamping member 163 is provided with a second clamping portion 163a. ​​When folded, the second movable member 162 rotates about the third axis A3, causing the second clamping member 163 to move together, so that the second clamping portion 163a rotates from the front side to the back side of the outer shell 12. Then, the second clamping member 163 rotates about the fourth axis A4 until the inner side of the second clamping portion 163a is in contact with the back side of the outer shell 12.

[0065] The first clamping assembly 14 and the second clamping assembly 16 are designed with dual-axis rotation, allowing them to flexibly switch between a working position and a folded position. In the working position, a stable clamping space is formed to secure the device; in the folded position, the clamping components fit against the back of the housing 12, achieving compact storage and improving portability and user experience.

[0066] Preferably, the first clamping assembly 14 further includes a first positioning structure disposed between the first movable member 142 and the first fixed member 141, for limiting the rotational position of the first movable member 142 relative to the first fixed member 141; the second clamping assembly 16 further includes a second positioning structure disposed between the second movable member 162 and the second fixed member 161, for limiting the rotational position of the second movable member 162 relative to the second fixed member 161. By providing positioning structures in the first clamping assembly 14 and the second clamping assembly 16, the rotational range of the movable member can be precisely limited, preventing excessive rotation or offset, ensuring the stability of the clamping assembly in the working state and the compactness in the folded state, and improving the reliability of the overall structure and the convenience of operation.

[0067] As an example, the first positioning structure includes a first positioning recess 141a disposed on the first fixing member 141, and a first positioning protrusion 144 elastically extendable disposed on the first movable member 142. When the first movable member 142 is in the working position or the folded position, the first positioning protrusion 144 is engaged in the first positioning recess 141a. As an example, the first movable member 142 is provided with a mounting hole (not shown in the figure) extending in a first direction. A spring (not shown in the figure) and a positioning pin (not shown in the figure) are sequentially installed in the mounting hole from the inside to the outside. One end of the positioning pin protrudes from the mounting hole to form the first positioning protrusion 144. Similarly, the second positioning structure includes a second positioning recess 161a disposed on the second fixing member 161, and a second positioning protrusion 164 elastically extendable disposed on the second movable member 162. When the second movable member 162 is in the working position or the folded position, the second positioning protrusion 164 is engaged in the second positioning recess 161a. By incorporating retractable positioning protrusions and corresponding positioning recesses, the design ensures stable engagement of the moving parts in the working or folded positions, preventing rotational shifting or loosening. This design not only improves the stability and operational accuracy of the clamping assembly but also facilitates position switching while maintaining the overall compactness and durability of the structure.

[0068] In one embodiment, the first movable member 142 is connected to the first fixed member 141 by a first fastener extending along a first direction, and each side of the first fastener is provided with a first positioning structure. As an example, the first fastener includes a first screw 145 and a first nut 146. The first fixed member 141 has a first positioning hole 141b in its center, and the first movable member 142 has a hollow first positioning post 142a in its center. The first positioning post 142a is inserted into the first positioning hole 141b, and the first screw 145 passes through the first positioning post 142a and the first positioning hole 141b before being connected to the first nut 146. Similarly, the second movable member 162 is connected to the second fixed member 161 by a second fastener extending along a first direction, and each side of the second fastener is provided with a second positioning structure. By providing positioning structures on both sides of the first and second fasteners, symmetrical and uniform positioning support can be provided for the movable member, further improving the accuracy and stability of the movable member's rotational positioning. The double-sided positioning design effectively prevents tilting or offset during rotation, while enhancing the overall structural strength and durability, making the clamping assembly more reliable and convenient. As an example, the second fastener includes a second screw 165 and a second nut 166. The second fixing member 161 has a second positioning hole 161b in the middle, and the second moving member has a hollow second positioning post 162a in the middle. The second positioning post 162a is inserted into the second positioning hole 161b, and the second screw 165 passes through the second positioning post 162a and the second positioning hole 161b and is connected to the second nut 166.

[0069] In one embodiment, the first clamping member 143 further includes a first connecting portion 143b extending inward from one end of the first clamping portion 143a to form an L-shaped structure, and the first connecting portion 143b is connected to the first movable member 142. The second clamping member 163 further includes a second connecting portion 163b extending to one side from one end of the second clamping portion 163a to form an L-shaped structure, and the second connecting portion 163b is connected to the second movable member 162. By designing the first clamping member 143 and the second clamping member 163 as L-shaped structures, the connection strength between the clamping member and the movable member is enhanced, while the structural layout of the clamping member is optimized, making it more compact and stable, adaptable to multi-angle clamping requirements, and improving overall performance and ease of operation. Preferably, the end of the first connecting portion 143b is provided with a U-shaped first groove 143c, the first movable member 142 is located in the first groove 143c, and is connected to the first connecting portion 143b through a first rotating shaft extending along the second axis A2. The second connecting part 163b has a U-shaped second groove 163c at its end. The second movable member 162 is located within the second groove 163c and is connected to the second connecting part 163b via a second rotating shaft extending along the fourth axis A4. By providing U-shaped grooves at the ends of the first connecting part 143b and the second connecting part 163b, a stable nesting between the movable member and the connecting part is achieved. Combined with the rotating shaft design extending along the axis, this not only allows the movable member to achieve flexible rotational movement but also improves the reliability and strength of the connection, preventing loosening or displacement during use. Simultaneously, the U-shaped groove structure simplifies the installation process and improves the processing and assembly efficiency of the product.

[0070] In one embodiment, a first cold shoe groove 143d is provided on the side of the first clamping part 143a opposite to the first connecting part 143b, and a second cold shoe groove 163d is provided on the side of the second clamping part 163a opposite to the second connecting part 163b. By providing cold shoe grooves on the first clamping part 143a and the second clamping part 163a, the mobile phone fixing device 1 can expand its function to install external devices (such as fill lights, microphones, etc.), further enhancing the product's versatility and applicability. The design of the cold shoe groove is compactly integrated with the layout of the clamping part, without affecting the overall use and aesthetics of the mobile phone fixing device 1, while providing users with more flexible device matching options to meet the needs of multiple usage scenarios.

[0071] Furthermore, the outer casing 12 includes a bottom shell 121 and a top cover 129. The front of the bottom shell 121 is provided with an annular receiving groove 122a for fixing the magnetic adsorption element 13. The magnetic adsorption element 13 is installed in the receiving groove 122a and is fixed in the bottom shell 121 by a tight fit to ensure stable magnetic adsorption effect. The top cover 129 has an annular structure and is used to cover the opening of the receiving groove 122a. The top cover 129 is connected to the bottom shell 121 by snap-fit ​​or adhesive, further enhancing the protective performance of the magnetic adsorption element 13 and preventing external forces from affecting its stability or causing damage.

[0072] In one embodiment, the bottom shell 121 includes a circular first outer shell 122 and a second outer shell 123 disposed on the back side of the first outer shell 122. The magnetic adsorption element 13 is housed within the first outer shell 122, and the second outer shell 123 extends along a first direction. The first telescopic component 15 and the second telescopic component 17 are housed within the second outer shell 123. By designing the circular magnetic adsorption element 13 as an embedded structure within the first outer shell 122, the stability and strength of the magnetic adsorption function are enhanced. The second outer shell 123 extends along the first direction to house the telescopic components, making the overall shell structure more compact and concealing the telescopic components, thus improving the product's aesthetic appearance. Furthermore, this design rationally separates the magnetic adsorption function and the telescopic function, facilitating assembly and use, and improving the product's practicality and design optimization.

[0073] Specifically, the second housing 123 is provided with two first mounting holes 123a and two second mounting holes 123b extending along a first direction. The first telescopic assembly 15 includes two first connecting rods 151 and two first springs 152. The first connecting rods 151 are arranged side by side, with one end located in the two first mounting holes 123a of the second housing 123, and can slide freely along the length direction of the first mounting holes 123a. The other end extends out of the first mounting holes 123a and connects to the first fixing member 141. The two first springs 152 are respectively sleeved on the two first connecting rods 151 located in the first mounting holes 123a, for applying an elastic clamping force between the second housing 123 and the first fixing member 141. Similarly, the second telescopic assembly 17 includes two second connecting rods 171, two second springs 172, and a second connecting block. The two second connecting rods 171 are arranged side by side, with one end located in the two second mounting holes 123b of the second housing 123, and the other end extending out of the second mounting holes 123b and connecting to the second fixing member 161.

[0074] In one embodiment, the first fixing member 141 has two first clearance holes 141c on its side facing away from the first movable member 142, and these two first clearance holes 141c correspond to the positions of the two second connecting rods 171. Thus, when folded, the other ends of the two second connecting rods 171 extend out of the two second mounting holes 123b and insert into the two first clearance holes 141c. This clearance design shortens the length of the second housing 123 along the first direction, thereby reducing the size of the clamping assembly in the folded state and improving portability. Similarly, the second fixing member 161 has two second clearance holes 161c on its side facing away from the second movable member 162, and these two second clearance holes 161c correspond to the positions of the two first connecting rods 151. Thus, when folded, the other ends of the two first connecting rods 151 extend out of the two first mounting holes 123a and insert into the two second clearance holes 161c. Similar to the design of the first clamping component 14, the structure is further optimized by setting the second clearance hole 161c, shortening the length of the second outer shell 123 along the first direction, and achieving a more compact storage effect. The design of the first clearance hole 141c and the second clearance hole 161c allows the connecting rod to effectively utilize the internal space of the fixing component when it is extended or retracted, without increasing the length of the second outer shell 123; after the clamping component is folded, the volume of the outer shell 12 and its internal components is minimized, making it easy to carry. At the same time, the clearance hole design cleverly utilizes the space of the fixing component, avoiding interference with other components after the connecting rod is extended; it ensures that the clamping component remains stable and does not loosen in both the extended and folded states. In addition, by shortening the length of the second outer shell 123, the entire clamping component appears more compact in the folded state, and the visual effect is more aesthetically pleasing and harmonious.

[0075] Furthermore, the outer casing 12 also includes a first reinforcing portion 124 and a second reinforcing portion 125 disposed on the back of the first outer casing 122 and located on both sides of the second outer casing 123 along the first direction. The first reinforcing portion 124, the second reinforcing portion 125, and one end of the second outer casing 123 along the first direction form a first storage groove 126. The first movable member 142 is located within the first storage groove 126. The other end of the first reinforcing portion 124, the second reinforcing portion 125, and the second outer casing 123 along the first direction forms a second storage groove 127. The second movable member 162 is located within the first storage groove 126. The design of the first reinforcing portion 124 and the second reinforcing portion 125 improves the overall strength and deformation resistance of the outer casing 12. Simultaneously, the formed first storage groove 126 and the second storage groove 127 provide fixed storage positions for the first movable member 142 and the second movable member 162. This structure effectively protects the movable members from external impact or wear when folded, and maintains the overall compactness and aesthetics of the outer casing 12. In addition, the arrangement of the reinforcement enhances the stability of the clamping components, further improving the product's durability and structural reliability.

[0076] In one embodiment, a soft pad 128 is fixed to the front of the first housing 122. The soft pad 128 is located inside the upper cover 129 and connected to the bottom housing 121. This is intended to provide additional cushioning and protection, preventing scratches or damage to the phone that may be caused by direct contact with hard materials. The soft pad 128 can be made of rubber, silicone, or other soft and durable materials, which not only absorb vibrations but also increase friction with the phone, preventing it from slipping during use.

[0077] In one embodiment, the outer casing 12 and the second end 112 of the support member 11 are rotatably connected by a rotating mechanism. In this way, the outer casing 12 can rotate around the support member 11 to achieve horizontal and vertical mounting. Specifically, the outer casing 12 is provided with a shaft hole 121a, and the second end 112 of the support member 11 is provided with a rotating shaft 114, which is inserted into the shaft hole 121a.

[0078] In one embodiment, the multi-functional photography bracket further includes a gimbal 4, which is rotatably connected to the connector 211 via a connecting shaft 18. The gimbal 4 is provided with an external screw 41 (or an external screw hole). In this way, when in use, photographic accessories such as fill lights can be installed on the gimbal 4, expanding the functionality of the multi-functional photography bracket.

[0079] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
