[0037] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] Existing stand devices are widely used for supporting and securing electronic devices, especially in the field of portable electronic devices such as laptops and tablets. Traditional stands mostly adopt a single folding or sliding structure, which can achieve angle adjustment and support of the device. However, in practical applications, these stand devices generally suffer from problems such as complex structure, cumbersome adjustment process, and insufficient stability, making it difficult to meet users' needs for portability and ease of use.

[0039] Specifically, the existing bracket devices have poor linkage in their folding structure, usually requiring users to manually adjust multiple components separately. This involves numerous and time-consuming steps, impacting efficiency. Furthermore, existing brackets lack stability in their unfolded state, especially when supporting heavy or large electronic devices, easily leading to vibration or swaying, affecting device safety and user experience.

[0040] Based on this, see Figures 1 to 7 As shown, this embodiment of the utility model provides a support device 10, which includes a base assembly 100, a support assembly 200, and a support assembly 300. The support assembly 200 is connected to the base assembly 100 and is used to support external electronic devices. There are at least two sets of support assemblies 300, which are respectively a first support assembly 300 and a second support assembly 300. The first support assembly 300 is movably connected to the base assembly 100, and the second support assembly 300 is movably connected to the support assembly 200. The support assembly 300 includes at least four frames 310, and the multiple frames 310 are connected in a transmission manner. In the unfolded state, two adjacent frames 310 are arranged at an angle, and in the folded state, two adjacent frames 310 are arranged in parallel.

[0041] The support device 10 of this embodiment achieves rapid switching between unfolded and folded states by setting at least two sets of support components 300, each set of support components 300 being composed of multiple frame bodies 310 connected by transmission. Compared with the traditional support device 10, which suffers from poor linkage and cumbersome operation, the multiple frame bodies 310 connected by transmission in this embodiment enable the support components 300 to be adjusted in a coordinated manner as a whole, making user operation simple, the adjustment process efficient, and significantly improving ease of use.

[0042] Furthermore, the first support assembly 300 on the base assembly 100 and the second support assembly 300 on the support assembly 200 each perform different support functions. The base-side support assembly 300 effectively stabilizes the placement of the device, while the support-side support assembly 300 provides robust support for external electronic devices. The included angle between the multiple frames 310 forms a stable geometric structure in the unfolded state, enhancing overall rigidity and load-bearing capacity. This improves upon the instability and wobbling issues of traditional computer stands in the unfolded state, thus ensuring the safety and stability of electronic devices during use. In the folded state, the frames 310 are arranged in parallel, significantly reducing the volume of the support device 10, improving portability, and meeting the compact size requirements of portable electronic devices. The overall structural design is simple and the transmission connection is reliable, reducing the number and complexity of parts, and lowering manufacturing difficulty and cost.

[0043] In one specific embodiment, the support assembly 300 consists of four frames 310, which are linked together via a transmission connection. Specifically, the four frames 310 are connected and arranged sequentially, and when switching between the unfolded and folded states, the rotation directions of two adjacent frames 310 are opposite. This design allows the four frames 310 to rotate synchronously, thereby achieving synchronous unfolding or folding of the entire support assembly 300.

[0044] The working principle of this structure is as follows: when the user operates any frame 310, the transmission connection mechanism will drive the adjacent frame 310 to rotate in the opposite direction. Through this alternating rotation direction, the four frames 310 can form a closed-loop motion system, ensuring that the entire support assembly 300 maintains a stable motion trajectory during unfolding or folding, and avoiding misalignment or jamming caused by the independent movement of a single frame.

[0045] Specifically, when unfolded, the four frame units 310 form a certain angle with each other, making the support assembly 300 a geometrically stable frame structure, improving overall rigidity and load-bearing capacity. When folded, the four frame units 310 overlap in parallel, significantly reducing the volume of the support device 10, making it easier to carry and store. In one embodiment, when unfolded, the angle between two adjacent frame units 310 can be set to 90°, that is, the four frame units 310 form an X-shaped structure when unfolded. This angle setting allows the four frame units 310 to form an approximately square or rectangular geometric structure after unfolding, thereby achieving a larger support range.

[0046] Specifically, the 90° angle between adjacent frame members 310 maximizes the support surface of the support assembly 300, thereby increasing the contact area and support area between the external electronic equipment and the support device 10. This structure helps to distribute the force on the equipment, reduce local stress concentration, and enhance overall stability and load-bearing capacity. By increasing the support range, the support device 10 can more effectively resist swaying or overturning caused by external forces, ensuring the safety and stability of the electronic equipment during use.

[0047] Furthermore, the 90° angle design facilitates the formation of a stable spatial frame structure. The four frame members 310 are arranged perpendicularly to each other, giving the entire support assembly 300 good rigidity and resistance to deformation. This structure can maintain shape stability when bearing heavy or large-sized equipment, reducing the risk of deformation and loosening.

[0048] It should be noted that although 90° is the preferred angle setting in this embodiment, the angle can also be adjusted appropriately according to specific application requirements. For example, the angle can be 45°, 60°, 75°, 90°, 105° or 120°, etc., to adapt to electronic devices of different sizes or shapes.

[0049] The four-frame 310 transmission connection design ensures simple operation. Users only need a single operating point to unfold or fold the support, avoiding the tedious steps of adjusting multiple parts one by one in traditional methods, thus improving adjustment efficiency. The design of adjacent frame 310 rotating in opposite directions also helps to reduce internal stress during mechanism movement, improving the durability and service life of the device.

[0050] Furthermore, the choice of four frames 310 balances structural stability and manufacturing cost. Specifically, the number of frames can be four, five, or six. A higher number of frames increases the stability and load-bearing capacity of the support structure, but also increases the complexity of the mechanical structure and manufacturing cost. In this embodiment, four frames 310 are chosen as a balance point, satisfying basic stability requirements while ensuring the simplicity of the device structure and the economy of manufacturing.

[0051] In one embodiment, the frame 310 is provided with teeth 311, and two adjacent frames 310 are connected by meshing teeth 311 to achieve a transmission connection. The teeth 311 enable adjacent frames 310 to transmit power and motion through a gear meshing mechanical structure. When the support device 10 switches between an unfolded state and a folded state, the rotation directions of two adjacent frames 310 are opposite, ensuring that the four frames 310 can rotate synchronously, thereby achieving synchronous unfolding or folding of the entire support.

[0052] The transmission scheme employing toothed connections 311 effectively improves the reliability of transmission connections between multiple frames 310. The toothed connections 311 provide high mechanical meshing accuracy for motion transmission, reducing energy loss and errors caused by slippage or sliding during transmission, and ensuring the rotational synchronization and positional accuracy of the frames 310. Furthermore, the toothed connections 311 can withstand large transmitted torques, making them suitable for support devices 10 requiring strong load-bearing capacity and stable movement. The shape and number of teeth of the toothed connections 311 can be determined according to specific design requirements; the tooth profile can be spur teeth, helical teeth, spiral teeth, etc., to adapt to different transmission smoothness and manufacturing process requirements.

[0053] It should be noted that the material and manufacturing precision of the tooth 311 have a significant impact on transmission performance. The tooth 311 can be made of metallic materials such as steel or aluminum alloy to ensure strength and wear resistance; alternatively, it can be made of high-strength engineering plastics to reduce weight and cost. The surface of the tooth 311 can be heat-treated or coated to improve wear resistance and service life.

[0054] In other embodiments, the frame 310 can also be connected by friction wheel contact. Specifically, friction wheels are provided at the ends of adjacent frame 310s, and the rotational torque is transmitted through the contact between the friction wheels, enabling the frame 310s to rotate synchronously. The friction wheel transmission method has a relatively simple structure, low manufacturing cost, and can achieve stepless transmission to a certain extent.

[0055] The advantages of friction wheel drives include compact structure, low transmission noise, and the elimination of the need for strict gear meshing, making them easy to adjust and maintain. However, friction wheel drives have high requirements for the material, surface treatment, and pressure of the contact surfaces; otherwise, slippage may lead to asynchronous transmission or reduced efficiency. Therefore, the friction wheels are typically made of high-friction, wear-resistant rubber, polyurethane, or similar materials, and the contact pressure between the friction wheels is ensured by springs or other pressure-applying devices.

[0056] Furthermore, the bracket assembly 300 also includes an anti-slip pad 320, which is disposed on the outside of the frame 310 and is mainly used to contact the ground, tabletop or contact surface of electronic equipment to improve the stability and anti-slip performance of the overall bracket device 10.

[0057] Specifically, the anti-slip pad 320 can be arranged on the outside of the frame 310 located on the support assembly 200. When the bracket device 10 is used to support electronic equipment, the anti-slip pad 320 contacts the electronic equipment. This arrangement increases the friction between the support surface and the electronic equipment, thereby reducing the risk of displacement or tilting of the equipment due to sliding during use. In addition, the anti-slip pad 320 also has a certain degree of elasticity and cushioning, which can protect the contact surface of the electronic equipment to a certain extent, reducing scratches or damage caused by rigid contact, thereby extending the service life of the electronic equipment and improving the user experience.

[0058] Meanwhile, the anti-slip pad 320 can also be placed on the outside of the frame 310 located on the base assembly 100, so that it contacts the table or the ground. This arrangement can increase the friction between the support device 10 and the placement surface, improve the stability of the support device 10 when placed, prevent the support from sliding or displacing due to external disturbances or forces during use, and ensure that the support device 10 and the supported electronic equipment can maintain a stable placement state.

[0059] The materials used for the anti-slip mat 320 can be soft materials with good friction and elasticity, such as rubber, silicone, polyurethane foam, and thermoplastic elastomers (TPE). The choice of material depends on the specific application environment and the required anti-slip and cushioning effects. For example, rubber has a high coefficient of friction and is suitable for applications requiring strong anti-slip properties; silicone is more elastic and wear-resistant, making it suitable for applications with high requirements for cushioning protection of electronic device surfaces. The shape and thickness of the anti-slip mat 320 can also be designed according to actual needs, such as flat, corrugated, or microstructured designs, to further improve anti-slip performance and cushioning effects.

[0060] It should be noted that the size and number of anti-slip pads 320 can be flexibly adjusted according to the structure and usage requirements of the support device 10. Specifically, the number of anti-slip pads 320 can be one, two, or more, evenly distributed on multiple contact points of the frame 310 to achieve a more uniform support and anti-slip effect. Using more anti-slip pads 320 can further improve the stability of the support device 10, but the overall structural compactness and aesthetics must also be considered.

[0061] Furthermore, the anti-slip mat 320 can be fixed using various methods such as adhesive bonding, mechanical snap-fit, or embedded installation, ensuring that it is not easily detached or shifted during use. Through reasonable design, the anti-slip mat 320 not only improves the safety of the bracket device 10 but also extends its service life, meeting the needs for stability and protection in different occasions.

[0062] In one embodiment, the support assembly 200 includes a base 210 and a support mechanism 220. A frame 310 is movably connected to the base 210, and a clearance groove 312 is provided on the frame 310. The support mechanism 220 is movably connected to the frame 310. The support mechanism 220 extends or retracts from the bearing surface of the frame 310 through the clearance groove 312, thereby supporting the electronic equipment.

[0063] Specifically, the support mechanism 220 is located on one side of the bearing surface of the frame 310 and can extend from the bearing surface of the frame 310 through the clearance slot 312, supporting the bottom of the electronic device. The purpose of this structural design is that when the support device 10 is in the unfolded use state, the support mechanism 220 can effectively support and carry the electronic device, ensuring the stable placement of the electronic device and preventing the device from tilting or sliding due to gravity or external forces. Due to the presence of the clearance slot 312, the support mechanism 220 will not interfere with other structural parts of the frame 310 when it extends, thereby ensuring the smoothness and reliability of the mechanism's operation.

[0064] Furthermore, when the support assembly 10 is in the folded state, the support mechanism 220 can retract into the inner side of the bearing surface of the frame 310 through the clearance slot 312, that is, retract into the clearance slot 312 or into a position basically flush with the bearing surface. This design prevents the support mechanism 220 from protruding from the bearing surface of the frame 310 in the folded state, preventing the overall compactness and portability of the support assembly from being affected by the exposed support mechanism, while reducing the risk of the support mechanism being hit by external forces during folding, thereby protecting the support mechanism 220 and related connecting parts from damage.

[0065] The dimensions and shape of the clearance slot 312 should meet the telescopic movement requirements of the support mechanism 220, ensuring that the support mechanism 220 can pass and extend smoothly while avoiding affecting the overall structural strength and load-bearing capacity of the frame 310 due to excessive slot size. The width, length, and depth of the clearance slot 312 can be reasonably designed according to the specific structural dimensions of the support mechanism 220. For example, the width of the clearance slot 312 can be 1.1 to 1.5 times the thickness of the support mechanism 220 to ensure movement space while avoiding structural looseness. Specific dimensions can be widths of 5mm, 7mm, 10mm, etc., and the depth should cover the fully retracted length of the support mechanism 220 to ensure that the support mechanism is not exposed when retracted.

[0066] Specifically, the support mechanism 220 includes a support pin 221 and a support shaft 222. The support pin 221 is rotatably connected to the frame 310 through the support shaft 222. The support pin 221 can rotate and switch between different positions around the support shaft 222, thereby realizing the function of extending or retracting the self-avoiding groove 312.

[0067] The support pin 221 forms a rotatable connection with the frame 310 via the support shaft 222, allowing the support pin 221 to switch between its position inside and outside the bearing surface of the frame 310. When the support pin 221 extends out of the clearance slot 312, it provides a support surface to support the bottom of the electronic device, ensuring stable placement of the electronic device. When the bracket device 10 is folded or stowed, the support pin 221 can rotate to avoid protruding from the bearing surface inside the clearance slot 312, ensuring the overall compactness and portability of the bracket structure.

[0068] To improve the durability of the support mechanism 220, the support shaft 222 can be made of a material with good wear resistance, such as high-hardness steel, stainless steel, ceramic-coated materials, or metal materials with nitrided surfaces. The application of wear-resistant materials can reduce the wear generated by the support shaft 222 during long-term repeated rotation, extend the service life of the support mechanism 220, and ensure the smoothness and reliability of its rotation.

[0069] The outer wall of the support pin 221 can be provided with a buffer layer. The buffer layer material can be a soft material with elasticity and a certain degree of wear resistance, such as rubber, silicone, polyurethane elastomer, or thermoplastic elastomer (TPE). The buffer layer can buffer the contact between the support pin 221 and the electronic device, reducing scratches, indentations, or other damage to the electronic device casing caused by rigid contact, thereby improving the protection effect of the electronic device.

[0070] When the buffer layer is made of materials with certain anti-slip properties such as rubber, it can also enhance the friction between the support pin 221 and the contact surface of the electronic device, further improve the support stability of the bracket device 10, and prevent the electronic device from sliding or tilting due to vibration or external force during the support process.

[0071] The buffer layer of the support pin 221 can be fixed to the outer wall of the support pin 221 by adhesive, in-mold molding, or mechanical snap-fit, ensuring that the buffer layer is not easy to fall off or shift during use. In addition, the shape of the buffer layer can be a whole-coverage type, a ring-shaped strip, or a localized dotted distribution to meet the needs of different electronic device contact surfaces, while taking into account both compact structure and buffering effect.

[0072] By adopting a rotating connection structure between the support pin 221 and the support shaft 222, combined with the wear-resistant support shaft 222 and the support pin 221 with a buffer layer, the support mechanism 220 can achieve the functions of extension and retraction, while improving durability and protection of electronic equipment, and enhancing stability during the support process, thus meeting the support needs and structural compactness requirements of different usage scenarios.

[0073] In one embodiment, the base 210 is provided with a first movable cavity 211 and a first limiting part 212. The frame 310 is movably accommodated within the first movable cavity 211, and the first limiting part 212 is located inside the first movable cavity 211, specifically for abutting against the side wall of the frame 310 when the frame 310 rotates to the end position of a predetermined path. This structural design limits the rotation range of the frame 310 through physical contact.

[0074] Specifically, the first movable cavity 211 forms the movable space of the frame 310, ensuring that the frame 310 can rotate within a certain angle range within the base 210. The first limiting part 212, as a protruding or blocking structure within the movable cavity 211, is located at the end position of the rotation path of the frame 310. When the frame 310 reaches this position, the side wall of the frame 310 contacts the first limiting part 212, preventing the frame 310 from continuing to rotate. This effectively limits the rotation angle of the frame 310, preventing the frame 310 from colliding, deforming, or detaching from the base 210 due to excessive rotation.

[0075] The design of this limiting structure does not rely on additional independent parts. Instead, the first limiting part 212 is formed by molding or setting a limiting protrusion inside the first movable cavity 211 of the base 210. This reduces the number of parts and assembly complexity, and helps to maintain the compactness and simplicity of the overall structure of the support assembly 200. In addition, the contact surface between the limiting part 212 and the side wall of the frame 310 can be designed as a plane, inclined plane, or curved surface according to actual needs to optimize the force distribution during limiting, reduce local stress concentration, and improve the durability of the structure.

[0076] The size, shape, and position of the first limiting part 212 can be reasonably determined according to the size and rotation angle range of the frame 310. For example, the height of the limiting part 212 can be 1mm, 2mm, 3mm, or greater, and the width and length can be 5mm, 8mm, 10mm, etc., respectively, to ensure effective limiting without excessively affecting the degree of freedom of movement of the frame 310. By adjusting the position of the limiting part 212, the maximum rotation angle of the frame 310 can be controlled, such as 30°, 45°, 60°, etc., and the specific angle range can be selected according to the usage requirements. If the size and position of the limiting part 212 are not reasonably set, the rotation range of the frame 310 may be insufficient, affecting the extension and retraction of the support mechanism 220, or the rotation may be too large, causing structural damage.

[0077] The sidewalls of the frame 310, serving as the limiting contact surface, should possess sufficient strength and wear resistance. Metal materials or surface-hardened engineering plastics are commonly used to withstand repeated limiting impacts. The fit tolerances between the base 210 and the frame 310 should be controlled within a reasonable range to ensure smooth rotation and timely and reliable limiting contact.

[0078] Furthermore, the base assembly 100 includes a base body 110, a rotating seat 120, and a locking mechanism 130, wherein the frame 310 is movably connected to the base body 110, the rotating seat 120 is rotatably connected to the base body 110, and the rotating seat 120 is connected to the support assembly 200. The base body 110 and the rotating seat 120 are engaged through the locking mechanism 130.

[0079] The specific implementation of the locking mechanism 130 may include one or more locking points, the number of which can be one, two, or more, and is not limited thereto. Multiple locking points provide multiple fixed positions, facilitating stable positioning of the rotating seat 120 at different angles to meet various usage requirements. For example, the angles corresponding to the locking points can be set to 30°, 60°, and 90°, with the specific angle range determined according to actual design requirements. Without properly setting locking points, the rotating seat 120 may over-rotate, leading to structural deformation or affecting the stability of the supporting component 200.

[0080] The material selection for the locking mechanism 130 can be based on requirements for mechanical strength, wear resistance, and elasticity, such as using spring steel, stainless steel, or engineering plastics (e.g., nylon, polyoxymethylene). A locking mechanism using elastic materials can provide good locking force, ensuring the stable fixation of the rotating seat 120 in the locking position, while also allowing the user to adjust the rotating seat 120 using a certain amount of external force.

[0081] The locking mechanism 130 not only limits the rotation angle of the rotating seat 120, but also avoids the introduction of additional complex structures, maintaining the compactness and ease of assembly of the base assembly 100. Furthermore, the structural dimensions, shape, and position of the locking mechanism 130 can be rationally designed according to the dimensions and usage requirements of the rotating seat 120 and the base 110, balancing the limiting effect with rotational flexibility.

[0082] Specifically, the locking mechanism 130 includes a locking member 131 and a locking spring 132, with the locking spring 132 connected to the locking member 131 and the seat 110 respectively. The rotating seat 120 has a plurality of locking slots 121 along its circumference, and the locking member 131 is used to engage with at least one of the locking slots 121.

[0083] Driven by the elastic force, the locking spring 132 pushes the locking member 131 into the slot 121 of the rotating seat 120, thereby achieving a stable locking engagement between the locking member 131 and the slot 121. This structure allows the locking member 131 to automatically enter the corresponding slot 121 position when the rotating seat 120 rotates, ensuring that the rotating seat 120 remains stably positioned at multiple preset angles and preventing over-rotation or unstable positioning.

[0084] Meanwhile, during the rotation of the rotating base 120, the collision between the locking component 131 and the slot 121 produces a mechanical feedback similar to a "clicking" sound. This mechanical sound serves as a tactile and auditory cue, reminding the user that the rotating base 120 has reached or passed a slot position, thereby enhancing the user's perception of the bracket angle adjustment status, facilitating accurate and convenient adjustment of the rotation angle, and improving the user experience.

[0085] The number of slots 121 can be designed according to application requirements, specifically 10, 15, 20 or more, evenly distributed to meet positioning requirements at different angles; the shape of the slots can be concave, arc-shaped or stepped to optimize snap-fit ​​stability and operating feel. The locking component 131 is usually made of a material with good elasticity and wear resistance, such as spring steel or engineering plastics, to ensure the durability and flexibility of the snap-fit.

[0086] The elastic coefficient of the locking spring 132 should be reasonably designed according to the size of the locking groove 121 and the structure of the locking component 131. It should ensure that the locking component 131 can reliably enter the locking groove 121, while avoiding excessive resistance to rotation and ensuring smooth adjustment. The spring material can be selected from materials with good elasticity and fatigue resistance, such as spring steel wire and nickel-titanium alloy wire.

[0087] In one embodiment, the base 110 is provided with a second movable cavity 111 and a second limiting part 112. The frame 310 is movably accommodated in the second movable cavity 111, and the second limiting part 112 is disposed inside the second movable cavity 111. It is mainly used to abut against the side wall of the frame 310 when the frame 310 rotates to the end position of the predetermined path, thereby limiting the rotation range of the frame 310.

[0088] Specifically, the second movable cavity 111 provides the frame 310 with a movable space, allowing it to rotate within a certain angle range. The second limiting part 112, as a structural protrusion inside the seat 110, is located at the end of the rotation path of the frame 310. When the frame 310 rotates to this position, its side wall contacts the second limiting part 112, preventing the frame 310 from continuing to rotate and preventing structural interference or damage caused by excessive rotation.

[0089] This limiting structure design requires no additional parts. It is formed by molding or embedding limiting protrusions inside the seat body 110, simplifying the structure and improving the overall compactness and assembly efficiency of the support components. The contact surface shape between the second limiting part 112 and the side wall of the frame 310 can be designed as a plane, slope, or curved surface to optimize stress distribution, reduce local stress concentration, and improve durability.

[0090] The dimensions and position of the second limiting part 112 can be reasonably determined according to the dimensions of the frame 310 and the expected rotation angle. For example, the height of the limiting part can be set to 1mm to 3mm, and the position arrangement ensures that the rotation angle of the frame 310 meets the design requirements, such as 30°, 45° or 60°. If the limiting part is not set properly, it may result in insufficient rotation range, affecting the normal extension and contraction of the support mechanism, or excessive rotation may cause damage to the mechanism.

[0091] The cooperation between the second movable cavity 111 and the second limiting part 112 achieves mechanical limitation on the rotation range of the frame 310, avoiding structural risks caused by excessive rotation, while maintaining the compactness and overall stability of the base assembly 100. This design helps improve the safety and durability of the support device 10.

[0092] Furthermore, the seat 110 is provided with an installation cavity 113, and the locking member 131 is provided with a receiving cavity 1311. The locking member 131 and the locking spring 132 are movably received in the installation cavity 113, and the locking spring 132 is at least partially received in the receiving cavity 1311.

[0093] The mounting cavity 113 provides a fixed and defined mounting space for the locking member 131 and the locking spring 132, allowing the locking mechanism 130 to be stably and compactly integrated into the base assembly 100. This prevents the locking member and spring from shifting or loosening during use, thereby improving the overall structural stability and reliability. The rational design of the mounting cavity 113 helps the base assembly 100 maintain a compact structure, reduces exposed parts, saves space, and enhances the product's aesthetic integrity.

[0094] The receiving cavity 1311 is a specially designed space inside the locking component 131 to accommodate part of the volume of the locking spring 132, thereby positioning and fixing the installation position of the locking spring 132. This design effectively limits the free deformation range of the locking spring 132, preventing excessive deformation or lateral swaying of the spring under force, ensuring that the spring operates within its elastic range, and improving the service life of the locking spring 132 and the elastic response stability of the locking mechanism.

[0095] By positioning the locking spring 132 through the receiving cavity 1311, the matching accuracy between the spring and the locking component 131 can be guaranteed, avoiding locking failure or spring damage caused by installation errors. At the same time, it helps to achieve the repeatability and reliable locking accuracy of the locking mechanism 130, and improves the angular positioning effect of the rotating seat 120.

[0096] Overall, the coordinated design of the mounting cavity 113 and the receiving cavity 1311 not only achieves compact installation of the locking component 131 and the locking spring 132, but also effectively limits and positions the spring deformation, improving the working performance and durability of the locking mechanism 130, and promoting the compactness and functional stability of the base assembly 100. This design helps meet the comprehensive requirements of the bracket device 10 for small size, robust structure, and reliable operation.

[0097] In one embodiment, the support device 10 further includes a linkage assembly 400, which is composed of a first linkage 410 and a second linkage 420. The first linkage 410 and the second linkage 420 are rotatably connected to achieve relative rotation. The first linkage 410 is movably connected to the base assembly 100, and the second linkage 420 is movably connected to the support assembly 200.

[0098] The design of the linkage assembly 400 ensures that the first linkage 410 and the second linkage 420 are arranged in parallel when in the storage position, making the entire support device 10 more compact, reducing space occupation, improving portability, and meeting the needs of portable electronic devices for a small and lightweight support device. In this position, the linkage assembly 400 is basically in a folded state, without interfering with the overall storage form of the support device.

[0099] When the support device 10 is in the open position, the first link 410 and the second link 420 rotate relative to each other, forming a certain angle, so that the support component 200 is effectively supported by the link assembly 400. At this time, the link assembly 400 establishes a mechanical connection between the support component 200 and the base assembly 100, which can withstand the weight of external electronic equipment and external loads, enhancing the stability and load-bearing capacity of the entire support device.

[0100] Furthermore, the angle of the support component 200 relative to the base component 100 can be easily adjusted via the rotatable connection of the linkage assembly 400. Users can adjust the tilt angle of the support component 200 according to their needs, thereby optimizing the viewing angle and user experience of the electronic device. The angle adjustment process is achieved through the relative rotation of the first linkage 410 and the second linkage 420, which is simple to operate and the adjustment range can be set according to design requirements.

[0101] Furthermore, a folding cavity 411 is provided on the first connecting rod 410, and the second connecting rod 420 can be accommodated in the folding cavity 411 when the support device 10 is in the retracted position. This design effectively reduces the overall thickness and volume of the connecting rod assembly 400 by reserving a dedicated space inside the first connecting rod 410, allowing the second connecting rod 420 to be partially or completely embedded in the folding cavity 411 of the first connecting rod 410.

[0102] The folding cavity 411 allows the first link 410 and the second link 420 to fit more tightly when folded, avoiding the extra thickness caused by their overlapping when folded, and significantly improving the compactness and portability of the support device 10. This nested folding design not only saves space, but also prevents the folded parts from being easily damaged by external impacts due to protrusion, thus improving the durability of the device.
