Abstract
Description
Technical Field
[0001] This utility model relates to the field of bracket technology, and in particular to a fixed bracket with multi-angle positioning. Background Technology
[0002] With the widespread use of smartphones and other portable electronic devices, users' needs for these devices are becoming increasingly diverse, especially when watching videos, making video calls, or taking photos, which places higher demands on the stability and angle adjustment of electronic devices. To meet these needs, various types of phone stands have emerged on the market, some of which are specifically designed with multi-angle adjustment capabilities in mind.
[0003] Existing phone holders, designed to accommodate electronic devices whether bent upwards or downwards, typically employ two opposing magnetic surfaces for secure attachment. While this method addresses the need for fixation in different bending configurations to some extent, it suffers from drawbacks in terms of portability and storage. The second connecting section, needing to cover both surfaces, results in a complex structure and a larger size. This makes the phone holder occupy excessive space when not in use, hindering its portability and storage in limited desktop or other storage spaces. Utility Model Content
[0004] The main purpose of this utility model is to provide a multi-angle positioning fixed bracket. The multi-angle positioning fixed bracket of this application has a simple structure, small size, and high flexibility.
[0005] To achieve the above objectives, some embodiments of this utility model propose a multi-angle positioning fixing bracket, which is suitable for detachably connecting electronic devices. The multi-angle positioning fixing bracket includes:
[0006] The first connecting part is suitable for connecting external components;
[0007] The flexible part is connected at one end to the first connecting part;
[0008] The second connecting part is connected to the other end of the flexible part. The second connecting part is adapted to connect to an electronic device. The second connecting part has a first sidewall adapted to abut against the electronic device.
[0009] The second connecting part is rotatable around the flexible part to adjust the orientation of the first sidewall.
[0010] In some embodiments, the extension direction along the straight state of the flexible portion is the first direction, the first axis is perpendicular to the first direction, the first circumferential direction and the second circumferential direction are both around the first axis, and the first circumferential direction and the second circumferential direction are opposite to each other.

[0013] In some embodiments, the second axis is parallel to the first axis, and when the flexible portion switches between the first state and the second state, the second connecting portion rotates about the second axis relative to the flexible portion to the first position or the second position.
[0014] In some embodiments, the flexible portion has a first through hole, and a second connecting portion is sleeved on the flexible portion, with at least a portion of the second connecting portion able to pass through the first through hole to adjust the orientation of the first sidewall;
[0015] or,
[0016] The flexible part includes a first rib that is bent and connected to a first connecting part at both ends. A second connecting part is sleeved on the first rib and can rotate around the first rib to adjust the orientation of the first sidewall.
[0017] In some embodiments, the multi-angle positioning fixing bracket includes a locking structure that connects the second connecting portion and the flexible portion respectively. The locking structure has a locked state and an unlocked state. In the locked state, the locking structure restricts the movement of the second connecting portion relative to the flexible portion. In the unlocked state, the second connecting portion is able to move relative to the flexible portion.
[0018] In some embodiments, the locking structure includes a second through hole and a pressure block, with a flexible portion passing through the second through hole and the pressure block protruding radially toward the center of the second through hole. In the locked state, the pressure block presses against the flexible portion, and in the unlocked state, the pressure block and the flexible portion are spaced apart.
[0019] In some embodiments, the pressure block includes a bolt that moves radially toward the center of the second through hole to lock the locking structure, or the bolt moves radially toward the side away from the center of the second through hole to unlock the locking structure.
[0020] In some embodiments, the first connecting portion includes a first connector and a second connector, both of which are adapted to connect to an external component. The flexible portion has two opposing ends, the two ends of which are respectively connected to the first connector and the second connector; and / or,

[0038] According to the above embodiments, the beneficial effects of this utility model are:
[0039] The multi-angle positioning bracket of this application is suitable for detachably connecting electronic devices. The multi-angle positioning bracket includes a first connecting portion, a flexible portion, and a second connecting portion. The first connecting portion is adapted to connect to an external component, providing a stable support base for the entire multi-angle positioning bracket and mounting it onto the external component. Through the first connecting portion, the multi-angle positioning bracket can be installed on various platforms, such as walls, desktops, and car dashboards. One end of the flexible portion is connected to the first connecting portion, and the other end is connected to the second connecting portion. The second connecting portion is adapted to connect to an electronic device and has a first sidewall adapted to abut against the electronic device. The second connecting portion is rotatable around the flexible portion to adjust the orientation of the first sidewall, thereby facilitating user operation of the electronic device.
[0040] The second connecting portion of this application can rotate independently around the flexible portion, meaning it has a higher degree of freedom. For example, when the flexible portion bends downwards, the first sidewall of the second connecting portion is located on the side facing the user. If the flexible portion is then changed to bend upwards, without rotating the second connecting portion, it will face the side away from the user as the flexible portion bends upwards, meaning the first sidewall will face the side away from the user. Since the second connecting portion of this application can rotate around the flexible portion, in this situation, the second connecting portion can rotate around the flexible portion by an appropriate angle to correct the first sidewall's orientation from facing away from the user to facing towards the user.
[0041] This application designs the second connecting part to be rotatable around the flexible part, thus requiring only one fixed surface. For example, when the electronic device is magnetically attached to the first sidewall, by controlling the rotation of the second connecting part, it ensures that the first sidewall can rotate to face the user regardless of the flexible part's various shapes, such as upward or downward bending. Compared to the existing design with two fixed surfaces, this application only requires one fixed surface (which can be understood as the first sidewall) to ensure that the electronic device faces the user regardless of the flexible part's shape. Therefore, this application has a simpler structure, smaller size, and greater flexibility. In summary, this application, through the bending design of the flexible part itself, combined with the design of the second connecting part rotating around the flexible part, achieves the effect of adjusting the position and orientation (angle) of the first sidewall, enabling multi-angle positioning of the electronic device and facilitating user operation.

[0061] 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.
[0062] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.
[0063] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where A and B are simultaneously satisfied. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
[0064] In order to ensure that electronic devices can face the user in both upward and downward bending of the flexible part, existing technologies use two fixed surfaces, such as two opposing magnetic surfaces, to fix the electronic devices. However, the second connecting part of the existing technology is bulky, difficult to store, and inflexible.
[0065] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 In some embodiments, this application proposes a multi-angle positioning mounting bracket suitable for detachably connecting electronic devices 600. The multi-angle positioning mounting bracket of this application includes a first connecting portion 100, a flexible portion 200, and a second connecting portion 300. The first connecting portion 100 is adapted to connect to an external component 500, providing a stable support base for the entire multi-angle positioning mounting bracket and mounting the entire multi-angle positioning mounting bracket onto the external component 500. The first connecting portion 100 can be designed in various shapes or sizes to accommodate different types of external components 500. The first connecting portion 100 can have a fixing structure with threaded holes or snap-fits to ensure stable attachment to the external device. Through the first connecting portion 100, the multi-angle positioning mounting bracket can be installed on various platforms, such as walls, desktops, and car dashboards, thus giving the multi-angle positioning mounting bracket a wide range of applications.
[0066] One end of the flexible portion 200 is connected to the first connecting portion 100. The flexible portion 200, serving as an intermediate connecting part between the first connecting portion 100 and the second connecting portion 300, possesses a certain degree of flexibility and elasticity. The bending and twisting of the flexible portion 200 allows the second connecting portion 300 to change at multiple angles relative to the first connecting portion 100, increasing the flexibility of the electronic device 600's placement and allowing users to adjust the angle and orientation of the electronic device 600 according to actual needs.
[0067] The second connecting portion 300 is connected to the other end of the flexible portion 200. The second connecting portion 300 is adapted to connect to the electronic device 600, and has a first sidewall 310 adapted to abut against the electronic device 600. Due to the characteristics of the flexible portion 200, the second connecting portion 300 can change its position or orientation as the flexible portion 200 rotates. The second connecting portion 300 of this application can rotate around the flexible portion 200, so this application can further adjust the orientation of the second connecting portion 300, that is, adjust the orientation of the first sidewall 310 according to the different bending shapes of the flexible portion 200, so that the electronic device 600 faces different directions to match the user's line of sight.
[0068] In summary, the second connecting portion 300 of this application can rotate independently around the flexible portion 200, meaning the second connecting portion 300 has a higher degree of freedom. For example, see reference... Figures 1 to 5 When the flexible portion 200 bends downwards, the first sidewall 310 of the second connecting portion 300 is located on the side facing the user. If the flexible portion 200 is then changed to an upward-bending state, without rotating the second connecting portion 300, it will face away from the user as the flexible portion 200 bends upwards, meaning the first sidewall 310 faces away from the user. In this application, the second connecting portion 300 can rotate around the flexible portion 200. Therefore, in this application, when faced with this situation, the second connecting portion 300 can rotate around the flexible portion 200 by an appropriate angle to correct the first sidewall 310 from facing away from the user to facing towards the user. This solution designs the second connecting part 300 to be rotatable around the flexible part 200, thus requiring only one fixed surface. For example, when the electronic device 600 is magnetically attached to the first sidewall 310, by controlling the rotation of the second connecting part 300, it ensures that the first sidewall 310 can rotate to face the user regardless of the various shapes of the flexible part 200, such as upward or downward bending. Compared to the existing design with two fixed surfaces, this application only requires one fixed surface (which can be understood as the first sidewall 310) to ensure that the electronic device 600 can face the user regardless of the shape of the flexible part 200. Therefore, this application has a simpler structure, smaller size, and greater flexibility.
[0069] Regarding the flexible portion 200, in this application, the flexibility of the flexible portion 200 refers to its ability to change shape. Specifically, the flexible portion 200 can be forced to change shape by an external force and return to its original shape after the external force is removed. Alternatively, the flexible portion 200 can be forced to change shape by an external force and retain its deformed form after the external force is removed. Furthermore, in some embodiments, the flexible portion 200 can be equipped with a mechanical motor, electric motor, or other drive structure, spontaneously and actively deforming. In some embodiments, the flexible portion 200 is a joint structure composed of multiple rigid segments (in this application, "flexible" is defined as the deformation being largely recoverable, and "rigid" is defined as having a stiffness higher than flexibility and being macroscopically difficult to recover after deformation). Changing the shape of the flexible portion 200 by adjusting this joint assembly also falls within the scope of the flexible portion 200 in this application. This application aims to highlight that the second connecting portion 300 can move relative to the flexible portion 200 to increase the degree of freedom of the second connecting portion 300. All the above configurations of the flexible portion 200 are within the protection scope of this application.
[0070] In some embodiments, the flexible portion 200 may be made of a highly elastic material, such as rubber or silicone, which is capable of returning to its original shape after being subjected to bending deformation within a certain range. (See reference...) Figure 3The flexible portion 200 can be a rod-shaped structure, such as a U-shaped rod. The second connecting portion 300 has a through hole, through which the flexible portion 200 passes, allowing the second connecting portion 300 to rotate relative to the flexible portion 200. Alternatively, the flexible portion 200 can be a sheet-like structure with a hollowed-out area. Near the hollowed-out area, the flexible portion 200 has a pivot structure for the second connecting portion 300 to rotate. The hollowed-out area allows part or all of the second connecting portion 300 to pass through, enabling the second connecting portion 300 to rotate around the flexible portion 200.
[0071] It is understood that, in some embodiments, to further enhance the functionality and applicability of the multi-angle positioning fixation bracket, the flexible portion 200, in addition to being made of a single material, can also be a composite structure composed of multiple segments, each segment connected by hinges or other similar mechanisms. This not only maintains the necessary flexibility but also enables more precise angle adjustment. For example, the flexible portion 200 can be composed of multiple small segments with gradually varying hardness. The hardness difference between each segment helps to form a more precise bending shape, thereby better supporting the different positional adjustments of the second connecting portion 300. Furthermore, shape memory alloy wires can be embedded inside the flexible portion 200. These alloy wires can automatically recover a preset bending shape after the externally applied force disappears, enhancing the memory function and stability of the multi-angle positioning fixation bracket.
[0072] Regarding the manner in which the second connecting part 300 connects to the electronic device 600 and / or the manner in which the first connecting part 100 connects to the external component 500, the connection with the corresponding object can be achieved through various methods such as magnetic attraction, suction cup, thread, buckle, strap, and adhesive.
[0073] Regarding the connection method of the first connecting part 100, specifically, in some embodiments, the first connecting part 100 includes a magnetic structure. The magnetic structure uses strong magnetic force to firmly attach the multi-angle positioning bracket to the metal external component 500, such as a car frame or refrigerator door panel. This connection method is not only convenient and quick to install and remove, but also has low requirements for surface flatness, making it suitable for applications requiring frequent position adjustments. In some embodiments, the first connecting part 100 includes a suction cup structure. The suction cup structure is suitable for smooth, non-porous surfaces, such as glass windows or mirrors. The suction cup uses atmospheric pressure to adhere tightly to the surface, providing sufficient support to fix the electronic device 600. When it is necessary to move the multi-angle positioning bracket, it can be easily removed by gently pulling the release valve. In some embodiments, the first connecting part 100 includes a threaded structure. The threaded structure allows the multi-angle positioning bracket to be directly screwed into the external component 500 with matching internal threads, such as a bicycle handlebar or tripod top. This connection method is very stable, especially suitable for applications that need to withstand heavy weight or be in a vibrating environment. In some embodiments, the first connection portion 100 includes a snap-fit structure. The snap-fit structure allows for quick locking onto a specific-shaped external component 500, such as a car air vent grille or the edge of a laptop. This connection method is simple to operate, requires no tools, and is ideal for temporary or emergency use. In some embodiments, the first connection portion 100 includes a strap structure. The strap structure is suitable for cylindrical or other external components 500 that are difficult to secure by other means, such as bicycle handlebars or pipes. The strap is typically made of nylon webbing with quick-release buckles at both ends for easy fastening and unfastening. In some embodiments, the first connection portion 100 includes an adhesive structure. The adhesive structure permanently or semi-permanently secures a multi-angle positioning bracket to the external component using strong adhesive or double-sided tape. This method is particularly suitable for installations requiring long-term fixation, such as walls or furniture surfaces.
[0074] Regarding the connection method of the second connecting part 300, specifically, in some embodiments, the electronic device 600 can be a tablet, mobile phone, e-reader, etc., and the second connecting part 300 connects to the electronic device 600 by means of magnetic attraction, snap-fit, adhesion, clamping, etc. In this case, the first sidewall 310 is the surface wall of the second connecting part 300 that abuts against the back of the tablet, the back of the mobile phone, or the back of the e-reader.
[0075] It is understood that in some embodiments, the first sidewall 310 of the second connection portion 300 may be provided with anti-slip texture or pads to increase the friction between the electronic device 600 and the electronic device 600 to prevent the electronic device 600 from accidentally slipping off.
[0076] In some embodiments, the first connecting part 100 may be equipped with a quick release mechanism to facilitate users to quickly install or remove the multi-angle positioning fixed bracket, thereby improving ease of use.
[0077] Reference Figure 6 In some embodiments, the extension direction of the flexible portion 200 in its straight state is a first direction X, a first axis is perpendicular to the first direction X, and both a first circumferential direction and a second circumferential direction are around the first axis, with the first circumferential direction and the second circumferential direction being opposite in direction. The flexible portion 200 is configured to have a first state of bending along the first circumferential direction and a second state of bending along the second circumferential direction. In the first state, the second connecting portion 300 is configured to be rotatable relative to the flexible portion 200 to a first position, and in the second state, the second connecting portion 300 is configured to be rotatable relative to the flexible portion 200 to a second position. (Refer to...) Figure 6 The first direction X is the extension direction of the flexible part 200 in its natural state. For example, the flexible part 200 extends in a straight line in its natural state, and this direction is defined as the first direction X. The first axis is perpendicular to the first direction X, and the flexible part 200 can bend around the first axis in two opposite directions, namely the first circumferential direction and the second circumferential direction, which are opposite to each other. This bidirectional bending capability gives the flexible part 200 greater flexibility, allowing the user to adjust the position of the second connecting part 300 according to actual needs.
[0078] When the flexible portion 200 is in the first state, that is, bent along the first circumferential direction, the second connecting portion 300 can rotate relative to the flexible portion 200 to a specific first position. This position is set based on the geometry and angle formed after the flexible portion 200 is bent, ensuring that the second connecting portion 300 can support or fix the electronic device 600 in a way that meets the user's needs. Similarly, when the flexible portion 200 switches to the second state, that is, bent along the second circumferential direction, the second connecting portion 300 can correspondingly rotate to a second position different from the first position. For example, the first state is when the flexible portion 200 is bent upwards, and the second state is when the flexible portion 200 is bent downwards. This design not only increases the adjustment range of the second connecting portion 300 but also ensures effective support for the electronic device 600 regardless of its position, allowing the user to adjust the angle of the electronic device 600 within a wider range, thus improving ease of use and adaptability.
[0079] Regarding the definition of bending of the flexible portion 200, the bending can be a bend along an arc or a bend along a line including a fold. The position of the second connecting portion 300 can be adjusted simply by changing the shape of the flexible portion 200.
[0080] In some embodiments, the connection between the flexible portion 200 and the second connecting portion 300 can also be improved. For example, the surface of the flexible portion 200 may be provided with a helical guide rail, while the second connecting portion 300 is equipped with a matching slider. When the flexible portion 200 bends, the slider moves along the guide rail, guiding the second connecting portion 300 to a predetermined first or second position. This design simplifies the mechanical structure while improving operational accuracy and response speed.
[0081] Reference Figure 4 and Figure 5 In some embodiments, when the second connecting portion 300 is in the first position, the first sidewall 310 is adapted to support the electronic device 600 upwards; when the second connecting portion 300 is in the second position, the first sidewall 310 is adapted to support the electronic device 600 upwards. The bending deformation of the flexible portion 200 guides the second connecting portion 300 to a predetermined position while ensuring that the first sidewall 310 is correctly oriented towards the user. Although the bending direction of the flexible portion 200 changes, the second connecting portion 300 can still ensure that the first sidewall 310 maintains a user-facing posture, facilitating the user's operation of the electronic device 600.
[0082] Understandably, the upward orientation of the first sidewall 310 supporting the electronic device 600 primarily means that the first sidewall 310 exposes the screen of the electronic device 600 to the user, rather than hiding it to the side away from the user. Here, "upward" does not mean absolutely facing upwards, but rather facing the user. This design facilitates user operation; for example, the user can place the electronic device 600 at a comfortable angle when watching videos, or quickly adjust the device's position to obtain the best viewing angle when making a video call.
[0083] Understandably, in some embodiments, to further enhance the stability of the first sidewall 310 at different positions, an automatic leveling mechanism can be provided inside the second connecting portion 300. This mechanism can automatically adjust the angle of the first sidewall 310 as the second connecting portion 300 moves with the bending of the flexible portion 200, ensuring that it always remains horizontal. The automatic leveling mechanism can be implemented using a built-in small motor and sensor. The sensor detects the degree and direction of bending of the flexible portion 200, and then the motor precisely adjusts the angle of the first sidewall 310 based on this information. In this way, even if the flexible portion 200 undergoes unexpected deformation, the first sidewall 310 can quickly return to the correct support position, providing higher reliability and safety.
[0084] Reference Figures 1 to 3In some embodiments, the second axis is parallel to the first axis. When the flexible portion 200 switches between the first and second states, the second connecting portion 300 rotates about the second axis relative to the flexible portion 200 to either the first or second position. This design ensures that when the flexible portion 200 bends about the first axis to transition from a straight state to a bent state (i.e., from the first state to the second state), the second connecting portion 300 can rotate about the second axis, which is parallel to the first axis, thereby adjusting the orientation of the first sidewall 310. The main benefit of this design is improved flexibility and adaptability of the multi-angle positioning bracket. Users can easily adjust the angle of the electronic device 600 according to actual needs without worrying about structural limitations. Furthermore, this design also increases the durability of the product because the reasonable force distribution reduces wear between components.
[0085] Regarding the definition of the second axis, further, the shape of the flexible part 200 can be regarded as a trajectory of an endpoint moving from a starting position to an ending position along a certain path. Therefore, the tangents of this trajectory can all be considered as the second axis. When the second connecting part 300 moves to a specific position in the trajectory, it also corresponds to a specific tangent, i.e., a specific second axis. The second connecting part 300 at a specific position rotates around the specific second axis to adjust the orientation of the first sidewall 310.
[0086] Understandably, in some embodiments, a bearing structure can be provided between the flexible portion 200 and the second connecting portion 300 to further optimize the rotational performance of the second connecting portion 300. The presence of the bearing will significantly reduce the friction between the two, making the second connecting portion 300 rotate more smoothly about the second axis. This improvement not only increases rotational efficiency but also extends the service life of the component by reducing wear caused by friction. The bearing can be a ball bearing or a sliding bearing, depending on the application environment and cost considerations.
[0087] It is understood that in some embodiments, a positioning device may be introduced to assist in fixing the second connecting part 300 in the first or second position. For example, a series of tiny grooves may be provided on the flexible part 200. When the second connecting part 300 rotates to a specific position, a small spring-loaded pin will automatically fall into the corresponding groove, thereby locking the position of the second connecting part 300. This design ensures that the second connecting part 300 can quickly and accurately stop at the target position when needed, and also facilitates manual unlocking and position adjustment by the user. This enhances the versatility of the multi-angle positioning fixing bracket and the user's ease of operation.
[0088] Reference Figure 3 and Figure 6In some embodiments, the flexible portion 200 has a first through hole 210, and a second connecting portion 300 is sleeved on the flexible portion 200. At least a portion of the second connecting portion 300 can pass through the first through hole 210 to adjust the orientation of the first sidewall 310. For example, the flexible portion 200 is a sheet-like structure with a perforated hole. At least a portion of the second connecting portion 300 can pass through this perforated hole, thereby adjusting the orientation of the first sidewall 310. In some embodiments, the flexible portion 200 includes a bent first rib 220, with both ends of the first rib 220 connected to the first connecting portion 100. The second connecting portion 300 is sleeved on the first rib 220 and can rotate around the first rib 220 to adjust the orientation of the first sidewall 310. For example, the first rib 220 is formed into a hollow ring, and at least a portion of the second connecting portion 300 can pass through this hollow ring, thereby adjusting the orientation of the first sidewall 310. This structure provides the first sidewall 310 with additional degrees of freedom, allowing it to be adjusted to the optimal position as needed.
[0089] Regarding the explanation of whether the second connecting portion 300 passes entirely or partially through the first through hole 210, specifically, allowing a portion of the structure of the second connecting portion 300 to pass through the first through hole 210 provides additional degrees of freedom for the second connecting portion 300, enabling adjustment of the orientation of the first sidewall 310 within a wider range. For example, the second connecting portion 300 includes a connecting structure sleeved on the flexible portion 200 and a clamping structure for connecting the electronic device 600. To securely connect the electronic device 600, the clamping structure needs to have stronger force, hence its volume is typically larger. The connecting structure sleeved on the flexible portion 200 can be designed to be smaller and can be integrated with the clamping structure through welding or threaded connections. In this case, only the connecting structure needs to pass through the first through hole 210; the clamping structure does not need to pass through the first through hole 210, and the second connecting portion 300 can still flexibly adjust the orientation of the first sidewall 310. Of course, if the second connecting portion 300 can pass entirely through the first through hole 210, the adjustment of the orientation of the first sidewall 310 will be even more flexible. This design simplifies the process of adjusting the orientation of the first sidewall 310, allowing users to quickly adjust the angle without complicated operations. Furthermore, because the second connecting portion 300 can at least partially pass through the second through hole 410, the second connecting portion 300 only needs to include one first sidewall 310 to ensure that the first sidewall 310 can face the user in both the first and second states of the flexible portion 200. This makes the entire structure more compact, reduces unnecessary space occupation, and improves the product's portability and flexibility.
[0090] It is understood that, in some embodiments, to further improve the stability of the second connecting portion 300 on the flexible portion 200, a guide structure can be provided inside the second through hole 410. For example, a spiral guide rail can be provided on the inner wall of the through hole, so that when the second connecting portion 300 passes through the through hole, it will move along a spiral path, which can not only prevent the second connecting portion 300 from accidentally falling off, but also provide a certain damping effect to help maintain the stability of the adjusted angle.
[0091] In some embodiments, the second through-hole 410 may also be designed as an ellipse or other non-circular shape to restrict the degree of freedom of the second connection 300 in certain directions, thereby achieving precise adjustment within a specific angle range. Such a design can increase the controllability of the adjustment process while ensuring flexibility, making it suitable for electronic devices 600 that have strict requirements for support angles.
[0092] In some embodiments, when the flexible portion 200 is configured as the first rib 220, a limiting device may also be provided on the first rib 220 to limit the maximum rotation angle of the second connecting portion 300 and prevent excessive rotation from causing structural damage. This limiting mechanism can be implemented through a simple mechanical structure, such as providing a stop or groove on the rib, thereby ensuring that the second connecting portion 300 operates within a safe range.
[0093] Reference Figures 1 to 3 as well as Figure 7 In some embodiments, the multi-angle positioning fixing bracket includes a locking structure 400, which connects the second connecting portion 300 and the flexible portion 200 respectively. The locking structure 400 has a locked state and an unlocked state. In the locked state, the locking structure 400 restricts the movement of the second connecting portion 300 relative to the flexible portion 200. In the unlocked state, the second connecting portion 300 is able to move relative to the flexible portion 200. The locking structure 400 is designed as an integrated component that is connected to both the second connecting portion 300 and the flexible portion 200. The locking structure 400 has an internal mechanical device that can switch between two states: a locked state and an unlocked state. In the locked state, the locking structure 400 physically restricts any movement of the second connecting portion 300 relative to the flexible portion 200; while in the unlocked state, this physical constraint is released, allowing the second connecting portion 300 to freely rotate or slide around or along the flexible portion 200 to adjust the orientation of the first sidewall 310. This design ensures that users can fix the position of the second connecting part 300 when needed, preventing accidental displacement caused by external forces, while also allowing users to flexibly adjust the angle according to actual needs.
[0094] The locking structure 400 operates by relying on the interaction between its internal mechanical components. When locked, specific components within the locking structure 400 (e.g., pawls, ratchet, etc.) come into close contact with the flexible portion 200, generating sufficient friction to prevent relative movement of the second connecting portion 300. Conversely, when unlocked, these components are released or retracted to positions that do not affect the flexible portion 200, thus removing the restriction on the second connecting portion 300. To achieve a smooth transition between these two states, in some embodiments, springs or other elastic elements are incorporated into the locking structure 400 to provide the necessary restoring force and ensure consistent and reliable operation.
[0095] The locking structure 400 enhances the safety of the multi-angle positioning bracket because once locked, the second connection 300 will not easily change position even under external vibration or impact, thus protecting the electronic device 600 connected to it. Secondly, the locking structure 400 allows users to precisely position the electronic device 600 at a stable angle, which is crucial for applications requiring a fixed viewing angle, such as watching videos, taking photos, or other scenarios.
[0096] It is understood that in some embodiments, the locking structure 400 can take many different forms to achieve the above-mentioned functions. For example, the locking structure 400 can be made of magnetic material, using the effect of a magnetic field to control the locking and unlocking process. In this case, a portion of the flexible part 200 may contain ferromagnetic material, while the locking structure 400 has a built-in permanent magnet. When the two are close together, the magnetic force will cause them to stick together tightly, forming a locked state; conversely, by applying an external force to overcome the magnetic attraction, the locking structure 400 can be disengaged from the flexible part 200 and enter the unlocked state. This magnetic-based locking scheme not only achieves a contactless operating experience but also reduces the wear problems that may occur in traditional mechanical locking structures 400.
[0097] In some embodiments, an intelligent control system can be incorporated into the locking structure 400 to enable automatic locking and unlocking. For example, sensors and a microcontroller can be embedded within the locking structure 400. The sensors detect changes in the angle of the second connecting portion 300 relative to the flexible portion 200, while the microcontroller determines whether to trigger a locking or unlocking action based on preset conditions. This not only improves the ease of use of the multi-angle positioning bracket but also enables more intelligent management, such as automatically locking after detecting that the electronic device 600 is in place, or automatically unlocking and issuing an alarm when abnormal tilting is detected. Such an intelligent locking structure 400 is particularly suitable for support systems of high-end electronic devices 600, providing additional security and technological added value.
[0098] In some embodiments, shape memory alloys can be used as the key material of the locking structure 400. Shape memory alloys have the property of returning to their original shape at specific temperatures. Specifically, when the temperature rises, the shape memory alloy contracts and adheres tightly to the flexible portion 200, achieving a locking effect; while when the temperature drops, it relaxes, allowing the second connecting portion 300 to move freely. By rationally designing the heating / cooling mechanism, the state transitions of the locking structure 400 can be precisely controlled, while also avoiding the failure points that are prone to occur in traditional mechanical locking structures 400.
[0099] Reference Figure 3 and Figure 8 In some embodiments, the locking structure 400 includes a second through hole 410 and a pressure block 420. A flexible portion 200 passes through the second through hole 410, and the pressure block 420 protrudes radially toward the center of the second through hole 410. In the locked state, the pressure block 420 presses against the flexible portion 200; in the unlocked state, the pressure block 420 and the flexible portion 200 are spaced apart. The locking structure 400 consists of the second through hole 410 and the pressure block 420. The second through hole 410 extends through the second connecting portion 300, allowing the flexible portion 200 to pass through it. The pressure block 420 is located near the second through hole 410 and can move radially along the second through hole 410, and can move radially toward or away from the center of the second through hole 410. When the pressure block 420 moves toward the center of the hole, it applies pressure to the flexible part 200, thereby achieving the locking function; when the pressure block 420 moves away from the center of the hole, it releases the pressure on the flexible part 200, allowing the flexible part 200 to move freely, i.e., entering the unlocked state. This design ensures that users can quickly switch between the working modes of the multi-angle positioning fixed bracket as needed, which is both stable and convenient.
[0100] The pressure block 420 generates friction through contact with the surface of the flexible portion 200. When the pressure block 420 is tightly fitted against the flexible portion 200, the friction between them is large enough that the second connecting portion 300 cannot move relative to the flexible portion 200, thus achieving a locking effect. Conversely, if this friction is reduced or eliminated (e.g., by removing the pressure block 420), the second connecting portion 300 can easily rotate or slide around the flexible portion 200 to adjust the orientation of the first sidewall 310. To ensure stable and reliable operation of the pressure block 420, a spring or other form of elastic element is typically installed inside, maintaining good performance even after repeated operations. This design is simple, reduces manufacturing costs, and improves assembly efficiency. Furthermore, because locking is achieved through direct physical contact, no additional power source is required, making operation more intuitive and simple, and suitable for use in various environments.
[0101] It is understood that in some embodiments, the surface of the pressure block 420 is recessed to fit the shape of the flexible portion 200 passing through the second through hole 410, so as to prevent the pressure block 420 from damaging the flexible portion 200.
[0102] Reference Figure 7 In some embodiments, the pressure block 420 includes a bolt 430 that moves radially toward the center of the second through hole 410 to lock the locking structure 400, or the bolt 430 moves radially toward the side away from the center of the second through hole 410 to unlock the locking structure 400.
[0103] Specifically, in this embodiment, the pressure block 420 is embodied as a bolt 430 assembly, which can move back and forth along the radial axis of the second through hole 410. One end of the bolt 430 is a smooth surface for contacting the surface of the flexible part 200; the other end is provided with a knob or screw head for easy manual operation by the user. When the user rotates the bolt 430 clockwise, the bolt 430 gradually moves towards the center of the hole until its smooth surface tightly adheres to the flexible part 200, at which point the locking structure 400 enters the locked state; conversely, when the bolt 430 is rotated counterclockwise, the bolt 430 retracts from the surface of the flexible part 200, thereby releasing the restriction on the flexible part 200 and allowing the locking structure 400 to enter the unlocked state. This bolt-based locking scheme combines the advantages of mechanical transmission and features a compact structure and high reliability.
[0104] The function of bolt 430 is to utilize the axial force generated by the helical pair to tighten or loosen the flexible part 200. When bolt 430 is tightened, the axial force generated by the helical pair pushes bolt 430 forward until its smooth surface is in full contact with the flexible part 200, generating sufficient positive pressure. This positive pressure is converted into friction, preventing relative displacement between the flexible part 200 and the second connecting part 300, ensuring the stability of the multi-angle positioning fixed bracket. In the unlocked state, by rotating bolt 430 in the opposite direction, the axial force generated by the helical pair disappears, bolt 430 returns to its original position, and the flexible part 200 can move freely. To improve the convenience and accuracy of operation, bolt 430 is usually equipped with scale markings to help users precisely control the degree of tightening.
[0105] The locking structure 400, which uses bolt 430 as a component of the pressure block 420, inherits the advantages of traditional mechanical locks, such as robustness, durability, and resistance to damage, making it suitable for long-term and frequent use. Furthermore, the operation of bolt 430 is intuitive and user-friendly. In addition, by rationally designing thread parameters (such as pitch and thread profile), bolt 430 can achieve a large range of axial displacement within a small rotation angle, improving locking speed and response sensitivity.
[0106] Understandably, in some embodiments, the bolt 430 may be designed to have a self-locking capability. For example, special friction washers may be added between the bolt 430 and the second through hole 410. These washers generate additional frictional resistance when the bolt 430 is tightened, preventing the bolt 430 from loosening due to vibration or other reasons. This self-locking function effectively improves the safety performance of multi-angle positioning brackets, and is particularly useful during vehicle operation or in other environments with vibration interference.
[0107] In some embodiments, the locking structure 400 also includes a button, which the user can press directly to adjust the state of the locking structure 400.
[0108] Reference Figures 1 to 3 In some embodiments, the first connecting portion 100 includes a first connecting member 110 and a second connecting member 120, both of which are adapted to connect to an external component 500. The flexible portion 200 has two opposing ends, which are respectively connected to the first connecting member 110 and the second connecting member 120. (Refer to...) Figure 8 The first connecting part 100 consists of two independent components: a first connector 110 and a second connector 120. Each of these components has the ability to engage with the external component 500, ensuring that the multi-angle positioning bracket can be stably installed in the designated position through different connection methods. The flexible part 200 acts as a bridge connecting the first connector 110 and the second connector 120, with its two ends fixed to these two components respectively, forming a complete support system. This design allows users to choose the most suitable installation method according to actual needs, and the spatial layout of the entire multi-angle positioning bracket can be optimized by adjusting the positions of the first connector 110 and the second connector 120.
[0109] In some embodiments, the first connecting portion 100 includes a main housing, a first connecting member 110, and a second connecting member 120. Both the first connecting member 110 and the second connecting member 120 are housed within the main housing. The main housing is adapted to connect to an external component 500. The flexible portion 200 has two opposing ends, which are respectively connected to the first connecting member 110 and the second connecting member 120. This method integrates the first connecting member 110 and the second connecting member 120 into a larger whole—the main housing. The main housing not only provides additional protection but also simplifies the installation process. In this configuration, the main housing is directly connected to the external component 500, the first connecting member 110 and the second connecting member 120 are housed inside the main housing, and the flexible portion 200 extends from the main housing and connects to the connecting portion. This method improves the portability of the entire multi-angle positioning fixed bracket.
[0110] In some embodiments, when the first connector 110 and the second connector 120 are directly exposed, they can directly contact and connect with other object surfaces. For example, if a threaded connection is used, fixing can be achieved simply by screwing the corresponding screw into a pre-prepared hole; if magnetic adsorption is used, it is necessary to ensure that the contact surfaces have sufficient metal material to generate sufficient attraction.
[0111] The first connecting part 100, designed in this way, can adapt to a variety of different installation scenarios, finding a suitable connection position whether it's a flat wall or a curved vehicle body. Secondly, the split-type connector design provides users with more flexibility, allowing them to flexibly adjust the angle and height of the multi-angle positioning fixing bracket according to actual conditions.
[0112] Regarding the two opposite ends of the flexible portion 200, it can be understood that the flexible portion 200 can be a rod-shaped structure with opposite ends; the flexible portion 200 can also be a polygonal structure, with two different corners of the polygon being the opposite ends of the flexible portion 200. The opposite ends are intended to distinguish the different positions of the flexible portion 200.
[0113] It is understood that in some embodiments, the first connector 110 and the second connector 120 can be designed as modular units, allowing users to replace different types of connectors as needed. For example, specially customized connection interfaces can be provided for target objects of different materials or shapes, such as nail-type connectors for wooden surfaces or strong suction cups for smooth surfaces such as glass. These modular connectors can be connected to the main housing or the multi-angle positioning fixed bracket body through a quick-release mechanism, greatly facilitating user operation.
[0114] In some embodiments, the outer surface of the main housing can be made into an arc shape or a handle-like design with grooves for easy handheld operation. Meanwhile, the housing material can be a lightweight yet high-strength composite material, reducing weight without compromising structural strength. Furthermore, anti-slip textures or coatings can be added to the housing surface to increase the sense of security when gripping.
[0115] In some embodiments, the first connecting portion 100 includes a magnetic attraction structure that magnetically attracts the external component 500; or, the first connecting portion 100 includes a threaded structure that threadedly connects to the external component 500; or, the first connecting portion 100 includes a strap structure that is bound to the external component 500; or, the first connecting portion 100 includes a suction cup structure that is attracted to the external component 500; or, the first connecting portion 100 includes an adhesive structure that is adhered to the external component 500; or, the first connecting portion 100 includes a nested structure that is interference-fitted with the external component 500; or, the first connecting portion 100 includes a snap-fit structure that snaps into the external component 500; or, the first connecting portion 100 includes a clamping structure that clamps the external component. 500; the second connecting part 300 includes a magnetic attraction structure, which magnetically attracts the electronic device 600; or, the first connecting part 100 includes a threaded structure, which threadedly connects to the electronic device 600; or, the first connecting part 100 includes a strap structure, which is bound to the electronic device 600; or, the first connecting part 100 includes a suction cup structure, which is attracted to the electronic device 600; or, the first connecting part 100 includes an adhesive structure, which is adhered to the electronic device 600; or, the first connecting part 100 includes a nested structure, which is interference-fitted with the electronic device 600; or, the first connecting part 100 includes a snap-fit structure, which snaps into the electronic device 600; the first connecting part 100 includes a clamping structure, which clamps the electronic device 600.
[0116] Specifically, the external component 500 can be a central control screen inside the vehicle (including the screen and the back of the screen), a central control box inside the vehicle, or other structures; in some embodiments, there are threaded holes inside the vehicle, and the first connecting part 100 includes bolts; in some embodiments, the external component 500 is a handlebar, and the first connecting part 100 is attached to the bicycle handlebar by a strap, etc.
[0117] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
