[0039] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0040] It should be noted that, unless otherwise stated, the technical or scientific terms used in this disclosure shall have the ordinary meaning as understood by one of ordinary skill in the art to which this disclosure pertains.

[0041] Currently, many electronic devices use screws to secure modules. When users replace modules themselves, the screws may fall onto the motherboard, potentially causing the device to overheat and burn out.

[0042] To solve the above-mentioned technical problems, this disclosure proposes a limiting device and electronic equipment that can avoid the risk of machine burnout caused by thread falling off.

[0043] Example 1

[0044] like Figure 1 and Figure 2 As shown, a limiting device includes a first structural member 2 and a second structural member 3. The first structural member 2 is fixed on a first target object 1, and the second structural member 3 is sleeved inside the first structural member 2 and slidably connected to the first structural member 2. When the second structural member 3 slides relative to the first structural member 2 to a first position, the second structural member 3 can contact the side of the second target object 4 away from the first target object 1 to limit the second target object 4 on the first target object 1.

[0045] The first structural component 2 is part of a limiting device, fixed to the first target object 1, i.e., the body 36 or frame of the electronic device. Its main function is to provide a basic platform allowing the second structural component 3 to slide within it, thereby limiting and fixing the second target object 4 (such as an electronic module). The first structural component 2 can be a guide rail type, designed as a linear guide rail, allowing the second structural component 3 to slide along one or more axes. This type is suitable for applications requiring precise position control. The first structural component 2 can also be a sleeve type structure with a hollow structure, allowing the second structural component 3 to be inserted and slide along its inner wall. This type of structural component is suitable for applications requiring a compact design. The first structural component 2 can also be a groove type structure, containing one or more grooves through which the second structural component 3 can slide. This design increases flexibility, allowing adjustment in different directions.

[0046] The first target object 1 is the main supporting structure of the electronic device, or a fundamental part of the device, whose function is to support and fix other components. For example, the first target object 1 can be the device housing: in this case, limiting devices can be fixed inside the housing to help install or replace internal components. The first target object 1 can also be a motherboard or circuit board. In some electronic devices, the first target object 1 may be a motherboard or circuit board. This allows modules to be directly installed on or near the motherboard, facilitating electrical connections. The first target object 1 can also be a chassis frame. For computers or other large electronic devices, the first target object 1 may be the device's chassis frame. Such a frame provides physical protection and supports the installation of various internal components. The first target object 1 can also be a dedicated mounting plate. In specific application scenarios, there may be mounting plates specifically designed for installing certain components as the first target object 1. These mounting plates can be customized as needed to accommodate the shape and size of specific components. The first target object 1 can also be part of a heat sink or cooling system: in high-performance computing devices, the first target object 1 can be part of a heat sink or cooling system, allowing heat-generating components to be directly installed in locations that facilitate heat dissipation.

[0047] The second structural component 3 refers to a part that can slide inside the first structural component 2 and adjust its position as needed. Its main function is to contact the second target object 4 when it slides to a specific position, and through this contact, securely fix the second target object 4 onto the first target object 1. This avoids problems that may occur with traditional fastening methods such as screws, such as the risk of electrical failure due to screws falling out. For example, the second structural component 3 can be a slider type, which is one of the most straightforward forms. The second structural component 3 is designed as one or more sliders that can slide within the guide rail or similar structure of the first structural component 2. This design is suitable for applications requiring simple and quick installation. The second structural component 3 can also have an adjustable clamping mechanism, which can be located on the side close to the second target object 4 to firmly grip it. This method is suitable for applications requiring high stability, ensuring the module is securely fixed in the designated position. The second structural component 3 can also be designed as a push-pull structure with a locking mechanism, allowing the user to lock or unlock the module's position through a simple push-pull operation. This type of design is typically used to improve user convenience. The second structural component 3 may also include a rotatable part, which allows for engagement or release with the second target object 4 through rotation. This provides additional stability and ease of operation. The second structural component 3 can also be an elastic clamping structure. Utilizing the elastic properties of the material, the second structural component 3 can be designed as a clamping structure that automatically adapts to target objects of different sizes. This design increases flexibility, allowing a single device to accommodate modules of various specifications.

[0048] The second target object 4 can be understood as a replaceable or fixed module, component, or part in an electronic device. It is securely mounted on the first target object 1 through cooperation with limiting devices (including the first structural member 2 and the second structural member 3). This design allows users to more easily install and remove modules while avoiding the risks associated with traditional fastening methods such as screws, such as electrical faults caused by loose screws. For example, the second target object 4 can be a functional module; in computers, expansion cards such as graphics cards, sound cards, and network cards are typical examples of second target objects 4. These modules provide additional functionality and can be added or removed as needed. The second target object 4 can also be a storage device, such as a hard disk drive (HDD) or solid-state drive (SSD). These devices are responsible for persistent data storage and often need to be upgraded or replaced based on capacity requirements. The second target object 4 can also be a battery pack; in portable electronic devices such as laptops, tablets, and smartphones, battery packs are typically considered second target objects 4. They provide power and may need to be replaced periodically. The second target object 4 can also be a heat dissipation module, including heat dissipation solutions such as fans, heat sinks, or liquid cooling systems. These are crucial for maintaining stable internal temperatures within the device. The second target object 4 can also be a display screen or touchscreen; in some portable devices, the display screen or touchscreen may be installed and replaced as a separate unit. The second target object 4 can also be a sensor assembly; in IoT devices or other smart devices, various types of sensors (such as temperature sensors, humidity sensors, motion sensors, etc.) can also be considered as the second target object 4. The second target object 4 can also be an interface module, including external interface modules such as audio jacks, used to connect external devices or accessories.

[0049] This disclosure involves fitting a second structural member 3 within and slidably connecting it to a first structural member 2. This allows the second structural member 3 to slide relative to the first structural member 2 to a first position, where it contacts the side of the second target object 4 furthest from the first target object 1, thus securing the second target object 4 onto the first target object 1. Specifically, when the second target object 4 needs to be installed on an electronic device, the second structural member 3 can slide to a specific position (the first position) where it contacts the second target object 4 and securely restrains it onto the first target object 1. This eliminates the need for screws during installation and fixation, facilitates disassembly, and avoids the risk of damage caused by loose threads.

[0050] like Figure 2 , Figure 3 and Figure 4As shown, in some modified embodiments of this disclosure, the first structural member 2 is provided with a card interface 25, and the second structural member 3 includes a card engaging part 37. The card engaging part 37 cooperates with the card interface 25. When the second structural member 3 slides relative to the first structural member 2 to the first position, the card engaging part 37 engages in the card interface 25.

[0051] The snap-fit ​​interface 25 refers to a specific structure or area on the first structural member 2, used to mate with the snap-fit ​​portion 37 on the second structural member 3. It receives and secures the snap-fit ​​portion 37, ensuring that the second structural member 3 remains firmly in place when slid to a designated position. For example, the snap-fit ​​interface 25 can be a groove, a recessed slot into which the snap-fit ​​portion 37 can be inserted. This design is simple and straightforward, suitable for applications requiring a clearly defined locking point. The snap-fit ​​interface 25 can also be a hole, a small hole passing through the first structural member 2, where the snap-fit ​​portion 37 locks by deformation (such as an elastic clip) or alignment before insertion into the hole. This method is suitable for designs requiring limited installation space. The snap-fit ​​interface 25 can also include a small hook or ring structure, with the snap-fit ​​portion 37 designed accordingly to hook or loop around this structure. This type provides additional security against accidental disengagement. In addition to the basic snap-fit ​​interface 25, guide grooves are provided to help guide the snap-fit ​​portion 37 into the correct position, and a locking point is provided at the final position to increase stability. Alternatively, magnetic materials can be used to make the card interface 25, and the card connector 37 can be fixed by magnetic attraction. This method is particularly suitable for applications that require quick assembly and disassembly.

[0052] The card interface 25 can be positioned at a critical location associated with the sliding path of the second structural member 3 to define its final positioning. The material and structure of the card interface 25 must possess sufficient strength to withstand the card connection force and maintain structural stability.

[0053] The snap-fit ​​portion 37 refers to the part located on the second structural member 3 that mates with the card interface 25. Its main function is to achieve fixation by matching the card interface 25 when the second structural member 3 slides to a predetermined position. The snap-fit ​​portion 37 can slide within the first structural member 2 along with the second structural member 3, and engages with the card interface 25 when it reaches a specific position (i.e., the "first position"). The snap-fit ​​portion 37 can have a certain degree of elasticity or a guiding structure to facilitate engagement and disengagement. For example, the snap-fit ​​portion 37 can be designed as a small protrusion that, when slid to the card interface 25, embeds into the groove or hole of the card interface 25 to form a lock. The snap-fit ​​portion 37 can also be a fastener made of elastic material, remaining open when not subjected to external pressure, compressing and then popping out to complete the lock when pushed into the card interface 25. This type of design allows for one-handed operation and is convenient for the user. The snap-fit ​​portion 37 can also be made in the shape of a hook, capable of hooking onto a corresponding structure in the card interface 25. This design increases the connection strength and is suitable for applications requiring high stability. The snap-fit ​​part 37 can also have a built-in button mechanism; pressing the button disengages the snap-fit ​​part 37 from the snap-fit ​​interface 25. This method improves ease of use, especially suitable for situations requiring frequent module replacement. The snap-fit ​​part 37 can also be a double-sided clamping structure, consisting of two opposing snap-fit ​​parts 37. By squeezing the sides, they retract and pass through the snap-fit ​​interface 25, then return to their original shape for secure fixing. This type is suitable for wider components.

[0054] In the initial state, the second structural component 3 is in a non-limited position, and the latching part 37 is not in contact with the card interface 25, allowing the module to be freely installed or removed. When the user pushes the second structural component 3 to slide towards the "first position": the latching part 37 slides along the first structural component 2; after reaching the designated position, the latching part 37 enters the card interface 25 and is physically locked; the second structural component 3 is fixed on the first structural component 2, while simultaneously pressing the second target object 4 (e.g., the module), limiting it to the first target object 1; if it is necessary to release the limitation, the user only needs to apply a certain external force to disengage the latching part 37 from the card interface 25, and then slide it back to its original position or remove the module.

[0055] The snap-fit ​​between the snap-fit ​​section 37 and the snap-fit ​​interface 25 provides clear feedback, enhancing user confidence and preventing misoperation. The snap-fit ​​structure effectively prevents the second structural component 3 from shifting due to vibration or other reasons during device operation. Users can lock and unlock the module without tools, improving maintenance efficiency. The snap-fit ​​structure does not occupy extra space, making it suitable for miniaturized electronic equipment applications.

[0056] like Figure 2 , Figure 3 and Figure 4As shown, in some modified embodiments of this disclosure, the second structural member 3 further includes a connecting portion 35, a pressing portion 34, and a main body 36. The connecting portion 35 is connected to the snap-fit ​​portion 37, and the connecting portion 35 can drive the snap-fit ​​portion 37 to move in a first direction away from the card interface 25. The pressing portion 34 is connected to the connecting portion 35, and the pressing portion 34 extends in the first direction and protrudes from the first structural member 2. The connecting portion 35 and the pressing portion 34 are disposed on the side of the main body 36 near the card interface 25.

[0057] The main body 36 is the primary supporting structure of the second structural member 3, and other components (such as the connecting part 35, the pressing part 34, and the snap-fit ​​part 37) are installed or integrated on it. The main body 36 can be made of a material with a certain strength, such as metal or plastic, and slides within the first structural member 2. The connecting part 35 is located on the side of the main body 36 near the snap-fit ​​interface 25, serving a connecting and transmission function. When subjected to external force (such as pressing), it can drive the snap-fit ​​part 37 to move in a specific direction (the first direction). The connection method between the connecting part 35 and the snap-fit ​​part 37 can be a fixed connection, a hinge, an elastic connection, etc., depending on the specific design. The first direction can be approximately perpendicular to the sliding direction. For example, if the second structure can slide vertically, the first direction can be horizontal.

[0058] The pressing part 34 is a component that allows the user to apply external force. By applying pressure to it, the connecting part 35 can be moved, thereby causing the latching part 37 to disengage from the card interface 25, thus achieving the unlocking function. The pressing part 34 is connected to the connecting part 35, extends in the "first direction," and protrudes from the first structural member 2. The user applies external force by pressing this part, thereby triggering the movement of the latching part 37. When the connecting part 35 is pressed, it moves away from the card interface 25, thus disengaging from the card interface 25 and achieving unlocking. The pressing part 34 can be designed in a shape that is easily accessible to the hand, such as a boss, button, or flange.

[0059] By combining the connecting part 35, the pressing part 34, the main body 36, and the locking part 37, a limiting mechanism with a clear structure, simple operation, and safe and reliable safety is constructed. Users can unlock the locking structure simply by pressing, without the need for tools. All components are concentrated on one side of the main body 36, making it suitable for small devices with limited space. Clear operation feedback (such as pressing feel and sound) enhances the user experience, making it especially suitable for electronic devices that require frequent module replacement and pursue efficient maintenance and user experience.

[0060] like Figure 3 As shown, in some modified embodiments of this disclosure, the connecting portion 35 includes an elastic segment 352 and a connecting segment 351. The elastic segment 352 is capable of elastic deformation during the process of the connecting portion 35 driving the snap-fit ​​portion 37 to move along the first direction. The snap-fit ​​portion 37 is disposed on the side of the connecting segment 351 near the snap-fit ​​interface 25.

[0061] The connecting segment 351 is a rigid or semi-rigid part connecting the snap-fit ​​portion 37 and the elastic segment 352. Its function is to transmit the pressing force from the elastic segment 352 to the snap-fit ​​portion 37. The connecting segment 351 usually maintains a stable shape and does not undergo significant deformation under normal operation. The snap-fit ​​portion 37 is located on the side of the connecting segment 351 near the snap-fit ​​interface 25 to ensure that it can be accurately inserted into or disengaged from the snap-fit ​​interface 25. The elastic segment 352 has material or structural features that can produce elastic deformation (such as thin wall, corrugated shape, spring structure, etc.). When the connecting portion 35 is subjected to a pressing force, the elastic segment 352 will deform (stretch, compress, bend, etc.). After the external force is removed, the elastic segment 352 can return to its original shape, driving the connecting segment 351 and the snap-fit ​​portion 37 back to their original positions. Multiple elastic segments 352 can be provided, or only one can be provided. For example, two elastic segments 352 can be provided symmetrically, with two narrower elastic segments 352 connected to a wider connecting segment 351.

[0062] In use, the locking part 37 is embedded in the locking interface 25 of the first structural member 2, limiting the second target object 4, and the elastic segment 352 is in its natural state. When the user presses the pressing part 34, the connecting segment 351 moves under force, the elastic segment 352 is compressed / bent, and the locking part 37 moves in the first direction, disengaging from the locking interface 25. When the locking part 37 is completely disengaged from the locking interface 25, the second structural member 3 slides within the first structural member 2, releasing the limitation on the second target object 4, and the module can be disassembled or replaced. When it is necessary to lock again, press and push the pressing part 34 to slide the second structural member 3 and the locking part 37 to the first position. After the external force is removed, the elastic segment 352 recovers its deformation, driving the connecting segment 351 and the locking part 37 back to their initial positions, locking the positions of the second structural member 3 and the second target object 4 again.

[0063] The flexible section 352 enables the device to automatically reset, facilitating user return to its original position and reducing the hassle of manual operation. The flexible design reduces impact forces during operation, extending structural lifespan and preventing component damage. The flexible section 352 can be integrally molded with the connecting section 351, reducing the number of parts and lowering manufacturing costs.

[0064] like Figure 2 , Figure 3 and Figure 4As shown, in some modified embodiments of this disclosure, a limiting structure 38 is provided on the main body 36. The limiting structure 38 is disposed within the orthographic projection of the connecting segment 351, and a gap is provided between the limiting structure 38 and the connecting segment 351. The connecting segment 351 can move in a first direction within the gap. When the connecting segment 351 contacts the limiting structure 38, the locking part 37 disengages from the card interface 25. By providing the limiting structure 38 on the main body 36 and forming a movable gap with the connecting segment 351, the movement range of the connecting segment 351 is precisely limited, preventing the user from excessively pressing the pressing part 34, which could cause the elastic segment 352 to break. This also ensures that the locking part 37 and the card interface 25 can reliably complete the unlocking action.

[0065] The limiting structure 38 is disposed on the main body 36 and located within the orthographic projection range of the connecting segment 351 (i.e., when viewed vertically from above, the limiting structure 38 covers the position area of ​​the connecting segment 351). The limiting structure 38 can be in the form of a protrusion, a stop, a groove, etc., used to limit the maximum range of movement of the connecting segment 351, leaving a gap between it and the connecting segment 351 to allow movement in the first direction. When unlocking, the connecting segment 351 moves in the first direction. At this time, it has not yet contacted the limiting structure 38 and is still within the gap. The connecting segment 351 continues to move until it contacts the limiting structure 38. At this time, the latching part 37 has disengaged from the card interface 25, the module is unlocked, and the limiting structure 38 prevents the connecting segment 351 from moving excessively, avoiding structural damage.

[0066] A limiting plate 23 can be provided on the side of the first structural member 2 away from the second target object 4. The limiting plate 23 can block the second structural member 3 along the sliding direction of the second structural member 3, thereby limiting the sliding direction of the second structural member 3 and preventing the second structural member 3 from coming off the first structural member 2.

[0067] like Figure 2 , Figure 3 and Figure 4 As shown, in some modified embodiments of this disclosure, the second structural member 3 further includes a first limiting part 31 and a second limiting part 32. The first limiting part 31 and the second limiting part 32 are arranged along the second direction. When the second structural member 3 slides relative to the first structural member 2 to the first position, the first limiting part 31 can limit the second target object 4, and the second limiting part 32 can limit the third target object 5. The third target object 5 and at least a portion of the second target object 4 are stacked along the second direction.

[0068] The first limiting part 31 is a mechanical structure disposed on the second structural member 3, used to limit the second target object 4 when the second structural member 3 slides to the first position, ensuring that it will not loosen or shift. For example, the first limiting part 31 can be a pressure-type limiting part, designed as one or more plates or arms that can apply downward pressure. When the second structural member 3 moves to the designated position, the second target object 4 is fixed by pressing, suitable for flat or flat target objects. The first limiting part 31 can also be a clamping limiting part, containing one or more pairs of adjustable-width clamps that can automatically adjust and clamp tightly according to the thickness of the target object. It is particularly suitable for modules with specific frames or shells, such as hard drives, memory modules, etc. The first limiting part 31 can also be an embedded limiting part, using a groove or hole design, so that part of the structure of the second target object 4 can be inserted into it to achieve physical locking, which is particularly effective for modules with specific pin or interface designs. The first limiting part 31 can also be a baffle-type limiting part, where a baffle is provided on one side of the second target object 4 to prevent it from moving in a certain direction. This is commonly used in situations where complete enclosure and fixation are not required, such as preventing circuit boards from shifting in a vibrating environment.

[0069] The second limiting part 32 is also provided on the second structural member 3, but it is used to limit the third target object 5. It typically engages with the third target object 5 in the second direction, possibly in the form of clamping, pressing, or blocking. For example, the second limiting part 32 can be a top-pressing limiting part, similar to the pressing method in the first limiting part 31, but specifically for the third target object 5 stacked on top. It can be a flat surface or a pressure plate with rubber pads, providing sufficient friction and protection to avoid surface damage. It can also be a side-clamping limiting part, designed to clamp the third target object 5 from the side, especially for modules with vertical edges. This type of limiting part is very useful for maintaining alignment between multiple stacked modules. The second limiting part 32 can also be a resilient clamping limiting part, made of springs or elastic materials, which can automatically adjust the clamping force according to the size of the third target object 5, suitable for modules that are frequently changed and have slightly different sizes. The second limiting part 32 can also be a hook-type limiting part, designed in a hook shape, which can hook the third target object 5 from above, usually used in conjunction with a bottom support. This is suitable for heavier or larger modules, such as large heat sinks. The second limiting part 32 can also be a multi-point contact limiting part, which can achieve limiting by distributing multiple contact points around the entire third target object 5, thereby increasing stability. It is especially suitable for modules with irregular shapes or uneven weight distribution.

[0070] The third target object 5 is an additional module located above or below the second target object 4, such as a heat sink, cover plate, auxiliary circuit board, hard drive bracket, etc. The third target object 5 and part of the second target object 4 are spatially stacked and need to be simultaneously restrained to ensure overall stability and electrical connection reliability. When the user pushes or slides the second structural component 3 to the first position, the two restraining parts begin to function. The first restraining part 31 contacts and presses against the second target object 4 (e.g., a solid-state drive), and the second restraining part 32 contacts and fixes the third target object 5 (e.g., a hard drive bracket). After the second structural component 3 is in place, the two restraining parts simultaneously fix the stacked modules (e.g., solid-state drives and hard drive brackets) onto the first target object 1, ensuring that they will not fall off or loosen due to vibration or external force.

[0071] By setting the first limiting part 31 and the second limiting part 32 along the second direction, stacked modules can be fixed simultaneously without multiple operations, improving assembly efficiency. Multiple limiting parts are integrated into a single sliding structure, saving space and making it suitable for miniaturized equipment. It can also simultaneously limit modules at multiple levels, preventing overall failure due to loosening of one layer. It is particularly suitable for modular electronic devices that support rapid assembly and disassembly, such as servers, industrial control equipment, and high-end laptops. Users can fix multiple modules with a single slide, enhancing ease of use.

[0072] like Figure 1 , Figure 5 and Figure 6 As shown, in some modified embodiments of this disclosure, a limiting block 21 is provided on the side of the first structural member 2 near the second target object 4, and a limiting groove 41 is provided on the side of the second target object 4 near the first structural member 2. The limiting groove 41 and the limiting block 21 cooperate to limit the second target object 4.

[0073] The limiting block 21 is provided with a first connecting hole 22, the third target object 5 has a second connecting hole 51, and the connecting structure 6 passes through the second connecting hole 51 and the first connecting hole 22 in sequence to fix the first structural member 2, the second target object 4 and the third target object 5 in a fixed connection.

[0074] The second structural member 3 includes a third limiting part 33. When the second structural member 3 slides relative to the first structural member 2 to the first position, the third limiting part 33 contacts the connecting structure 6 to limit the connecting structure 6.

[0075] A limiting block 21 is located on the side of the first structural component 2 near the second target object 4, and has a first connecting hole 22 inside. It provides lateral limiting for the second target object 4 and provides a through-hole path for the connecting structure 6, facilitating multi-level fixing. A limiting groove 41 is located on the second target object 4 and matches the outer structure of the limiting block 21, ensuring that the second target object 4 will not shift or rotate during assembly. The connecting structure 6 can use fasteners such as screws, pins, and rivets; these fasteners pass sequentially through the second connecting hole 51 and the first connecting hole 22, connecting the first structural component 2, the second target object 4, and the third target object 5 into a single unit.

[0076] The third limiting part 33 is disposed on the second structural member 3. When it slides to the first position, it contacts the connecting structure 6 and applies pressure to limit it, preventing the connecting structure 6 from loosening or falling off due to vibration or impact, thus playing the role of "anti-loosening lock". The specific structure of the third limiting part 33 can be the same as that of the first limiting part 31 and the second limiting part 32. For example, it can be a plate-shaped pressing structure, etc., which will not be described in detail here.

[0077] The combination of limit block 21, limit groove 41, connecting structure 6, and third limit part 33 achieves a complete process from positioning to fixing, and the multi-point locking mechanism ensures structural stability even in complex environments. The modular design supports quick replacement; users can complete all locking actions with a single slide. The third limit part 33 provides secondary protection for the connecting structure 6, avoiding the risk of screws falling out and improving the equipment's safety level.

[0078] like Figure 5 and Figure 7 As shown, in some modified embodiments of this disclosure, a first guide structure 321 is provided on the side of the second limiting part 32 that is relatively close to the third target object 5, and a second guide structure 52 is provided on the side of the third target object 5 that is close to the second limiting part 32. The first guide structure 321 and the second guide structure 52 are adapted to each other. By providing the first guide structure 321 and the second guide structure 52 between them, key functions such as precise alignment, smooth sliding, and prevention of offset are achieved, thereby improving the overall assembly efficiency and reliability.

[0079] The first guide structure 321 is located on the side of the second limiting part 32 relatively close to the third target object 5, and can be in the form of a protrusion, guide rail, bevel, groove, etc. Its purpose is to guide the third target object 5 into the correct installation position during assembly, acting as a "pre-positioning" mechanism to prevent connection failure or module damage due to misalignment. The second guide structure 52 is located on the side of the third target object 5 close to the second limiting part 32, and its shape is adapted to the first guide structure 321, such as a groove, slot, guide hole, bevel, etc. During assembly, it cooperates with the first guide structure 321 to ensure that the third target object 5 enters the limiting area along the correct path; improving assembly consistency, especially suitable for space-constrained or automated assembly scenarios.

[0080] The guiding structure ensures that the third target object 5 accurately enters the designated position every time, reducing human error. It avoids module damage caused by incorrect insertion direction or tilting, especially for precision circuits or interface components. In assembly environments without visual assistance (such as dark chambers or robotic assembly), the guiding structure significantly improves the success rate. Smooth guiding provides a good feel, enhancing user confidence and ease of operation. The guiding structure can be adjusted according to different shapes and sizes of the third target object 5, exhibiting good versatility. For example, it can be set with inclined surfaces or curved surfaces + ramps. The first guiding structure 321 has an inclined surface for alignment guidance, while the second guiding structure 52 is a matching inclined or curved surface structure, providing strong self-correction capabilities and suitable for assembly with large tolerances.

[0081] like Figure 1 and Figure 2 As shown, in some modified embodiments of this disclosure, a third structural member 7 is also included. The third structural member 7 is fixedly connected to the outside of the first structural member 2. A connecting surface 72 is provided on the side of the third structural member 7 away from the first structural member 2. A first connecting portion 24 is provided on the side of the first structural member 2 away from the second target object 4. A second connecting portion 71 is provided on the side of the third structural member 7 close to the second target object 4. The first connecting portion 24 and the second connecting portion 71 are fixedly connected to the first target object 1, respectively.

[0082] For example, the third structural member 7 can be a reinforcing rib type, with metal / plastic ribs with connection holes added to one side of the first structural member 2, suitable for applications requiring load-bearing capacity in industrial equipment and servers. The third structural member 7 can also be designed as an L-shape, connecting to both the first structural member 2 and the first target object 1. The third structural member 7 can also extend outwards and be fixed as part of the outer shell. The third structural member 7 can also have multiple connection holes to adapt to different installation requirements and is suitable for flexible configuration modular systems. The third structural member 7 can also be an elastic connection type, with built-in elastic elements to achieve a buffering and fixing function. The connecting surface 72 is located on the side of the third structural member 7 away from the first structural member 2, for contacting or connecting with other components (such as the suction cup of a robotic arm); providing a mounting contact surface for easy and stable assembly.

[0083] The first connecting part 24 is located on the side of the first structural member 2 away from the second target object 4. The first connecting part 24 may include connecting structures 6 such as holes, snaps, threaded posts, connection points, or connecting patches, and may be connected to the first structural member 2 using surface mounting or welding technology, for fixing the first structural member 2 to the first target object 1. The first connecting part 24 is located on the side of the third structural member 7 away from the second target object 4, and its form is similar to the first connecting part 24. It may be other fastening structures such as holes, screw posts, connection points, or connecting patches, to achieve an additional fixed connection between the third structural member 7 and the first target object 1.

[0084] The third structural component 7 and the first structural component 2 can be welded or connected in a detachable manner. For example, the third structural component 7 and the first structural component 2 can be connected by a slot and a buckle.

[0085] By introducing a third structural component 7 and forming a multi-point fixed connection structure 6 with the first structural component 2 and the first target object 1, not only is the installation strength and stability of the entire limiting device in the electronic device enhanced, but the overall mechanical rigidity and vibration resistance are also improved.

[0086] Example 2

[0087] like Figure 1 and Figure 5 As shown, an electronic device includes a first target object 1, a second target object 4, and a limiting device. The second target object 4 is disposed on one side of the first target object 1. The limiting device includes a first structural member 2 and a second structural member 3. The first structural member 2 is fixedly connected to the first target object 1. The second structural member 3 is sleeved inside the first structural member 2 and slidably connected to the first structural member 2. When the second structural member 3 slides relative to the first structural member 2 to a first position, the second structural member 3 can contact the side of the second target object 4 away from the first target object 1 to limit the second target object 4 onto the first target object 1.

[0088] Electronic devices can be mobile phones, computers, tablets, servers, etc. The first target object 1 can be understood as the basic structural part of the electronic device, such as the device casing or motherboard bracket. The second target object 4 refers to the functional modules that need to be installed on the first target object 1, such as memory modules, SSDs, or other expansion cards. The limiting device is used to securely fix the second target object 4 to the first target object 1, preventing loosening or detachment due to vibration or other reasons. The specific structures of the first target object 1, the second target object 4, and the limiting device can be as described in Embodiment 1, and will not be repeated here.

[0089] In the initial state, the second structural member 3 is in a non-restricted position, allowing the user to freely insert or remove the second target object 4. The user slides the second structural member 3 along the first structural member 2 to the "first position" by manually pushing or pressing. In this position, one end of the second structural member 3 contacts the side of the second target object 4 away from the first target object 1 and applies appropriate pressure to firmly press it onto the first target object 1.

[0090] At this time, the second target object 4 can also be effectively confined to the designated position to ensure that it will not move or fall off due to external vibrations or other factors.

[0091] This disclosure involves fitting a second structural component 3 within a first structural component 2 and slidably connecting it to the first structural component 2. This allows the second structural component 3 to slide relative to the first structural component 2 to a first position, where it contacts the side of the second target object 4 away from the first target object 1, thus securing the second target object 4 onto the first target object 1. Specifically, when the second target object 4 needs to be installed on the electronic device, the second structural component 3 can slide to a specific position (the first position) where it contacts the second target object 4 and securely restrains it onto the first target object 1. This eliminates the need for screws during installation and fixation, facilitates disassembly, and avoids the risk of damage caused by loose threads.

[0092] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
