Description

Technical Field

[0001] This disclosure relates to the field of electronic equipment technology, and in particular to a board fixing mechanism and an electronic device. Background Technology

[0002] In traditional electronic devices, PCBs, SSDs, WiFi modules, and other circuit boards are commonly installed using screws. However, when using a screwdriver to install screws, the operating space is often quite limited, and the screwdriver can easily accidentally touch surrounding components. This not only poses a risk of scratching or knocking down components, but also the possibility of static electricity or mechanical stress generated by the impact, which can damage sensitive electronic components and reduce the assembly quality and reliability of the product. Summary of the Invention

[0003] This disclosure provides a board fixing mechanism and an electronic device to at least solve the above-mentioned technical problems existing in the prior art.

[0004] The first aspect of this disclosure provides a board fixing mechanism for connecting a first structural member and a second structural member, comprising:

[0005] A connecting component is connected to the first structural member;

[0006] A rotating component is rotatably connected to the connecting assembly;

[0007] The rotating component is provided with a snap-fit ​​part. When the rotating component rotates to the first position, the snap-fit ​​part snaps into the second structural component, so as to connect the first structural component and the second structural component.

[0008] Furthermore, the connecting assembly includes a first connector and a second connector, the first connector being fixedly connected to the first structural member, and the second connector being threadedly engaged with the first connector.

[0009] Furthermore, the rotating component includes a first annular portion and a second annular portion, both of which are sleeved on the connecting assembly;

[0010] The first annular portion and the second annular portion are spaced apart along the axial direction of the rotating member, and a mounting position for mounting the second structural member is formed between the first annular portion and the second annular portion.

[0011] Furthermore, the first annular portion is formed with a crimping portion, and the crimping portion and the second annular portion form the snap-fit ​​portion, the crimping portion being used to abut against the second structural member when the rotating member rotates to the first position.

[0012] Furthermore, the crimping portion has a guide surface.

[0013] Furthermore, the first connector is provided with a first boss, and a first limiting part and a second limiting part are formed on the outer side of the first boss. The first limiting part and the second limiting part are spaced apart along the circumference of the first boss.

[0014] The inner side of the second annular portion has a mating portion, which mates with one of the first limiting portion and the second limiting portion. When the mating portion mates with the first limiting portion, the rotating member rotates to the first position. When the mating portion mates with the second limiting portion, the rotating member rotates to the second position.

[0015] Furthermore, the first connector is provided with a second boss, the outer side of the second boss is formed with a first tooth-shaped structure, the inner side of the second annular portion is formed with a second tooth-shaped structure, and the second tooth-shaped structure cooperates with the first tooth-shaped structure.

[0016] Furthermore, the rotating component is made of an elastic material.

[0017] Furthermore, the rotating member includes a toggle part, which is connected to at least one of the first annular portion and the second annular portion.

[0018] A second aspect of this disclosure provides an electronic device including the board fixing mechanism described in the first aspect.

[0019] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0020] The circuit board fixing mechanism provided in this embodiment includes a connecting component and a rotating component. The connecting component is connected to a first structural component, and the rotating component is rotatably connected to the connecting component, allowing the rotating component to rotate relative to the connecting component. The rotating component has a locking portion; when the rotating component rotates to a first position, the locking portion engages with a second structural component, connecting the first and second structural components. In use, the second structural component can be placed near the connecting component, specifically abutting against it. Then, the rotating component is rotated to the first position, where the locking portion engages with the second structural component, thus fixing the first and second structural components together. When the second structural component needs to be disassembled, simply rotate the rotating component in the opposite direction to separate the locking portion from the second structural component, thereby separating the first and second structural components. The circuit board fixing mechanism provided in this embodiment eliminates the need for a screwdriver, avoiding the risk of screwdrivers hitting components or causing collisions during use.

[0030] To make the objectives, features, and advantages of this disclosure more apparent and understandable, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0031] The board fixing mechanism provided in this embodiment is used to connect the first structural component 1 and the second structural component 2. The first structural component 1 can be a motherboard, and the second structural component 2 can be a board. The board can include various types such as PCB, SSD, and WiFi.

[0032] Combination Figure 1 and Figure 2 As shown, the plate fixing mechanism includes a connecting component 3 and a rotating component 4. The connecting component 3 is connected to the first structural component 1, and the connecting component 3 and the first structural component 1 can be fixedly connected or detachably connected. Optionally, the connecting component 3 and the first structural component 1 can be connected by welding. The rotating component 4 is rotatably connected to the connecting component 3, allowing the rotating component 4 to rotate relative to the connecting component 3. The rotating component 4 is provided with a locking part 43, which can be a groove or slot, etc. When the rotating component 4 rotates to the first position, the locking part 43 engages with the second structural component 2, thereby connecting the first structural component 1 and the second structural component 2. In use, the second structural member 2 can be placed near the connecting component 3, specifically abutting against the connecting component 3. Then, the rotating member 4 is rotated in the first direction to the first position, where the snap-fit ​​portion 43 on the rotating member 4 snaps into the second structural member 2, thereby fixing the first structural member 1 and the second structural member 2 together. When it is necessary to disassemble the second structural member 2, simply rotate the rotating member 4 in the opposite direction to the first direction to separate the snap-fit ​​portion 43 from the second structural member 2, thus separating the first structural member 1 and the second structural member 2. The installation and disassembly process does not require the use of a screwdriver, saving time and effort during assembly. The board fixing mechanism provided in this embodiment does not require the use of a screwdriver, avoiding the risk of screwdrivers hitting components or causing collisions during use.

[0033] The first direction can be either clockwise or counterclockwise.

[0034] In some specific implementation methods, such as Figure 3 The connecting assembly 3 includes a first connecting member 31 and a second connecting member 32. The first connecting member 31 is fixedly connected to the first structural member 1, and the second connecting member 32 is threadedly engaged with the first connecting member 31. Optionally, the first connecting member 31 and the first structural member 1 can be connected by welding, and the second connecting member 32 can be threadedly connected to the first connecting member 31 to form a pre-assembled structure, which is simple in structure and easy to operate. During installation, after the first connecting member 31 is fixed to the first structural member 1, the rotating member 4 can be placed on the first connecting member 31. After the second connecting member 32 is connected to the first connecting member 31, the second connecting member 32 can limit the axial movement of the rotating member 4. Optionally, the first connecting member 31 can be a stud with internal threads, and the second connecting member 32 can be a screw. The screw includes a head and a shank that are connected to each other. The shank has external threads, and the internal threads engage with the external threads. The head is used to limit the movement of the rotating member 4.

[0035] In some specific implementation methods, such as Figure 4As shown, the rotating member 4 includes a first annular portion 41 and a second annular portion 42, both of which are sleeved on the connecting assembly 3; both the first annular portion 41 and the second annular portion 42 can rotate relative to the connecting assembly 3. When the connecting assembly 3 includes a first connecting member 31 and a second connecting member 32, and the first connecting member 31 is fixed to the first structural member 1, both the first annular portion 41 and the second annular portion 42 are sleeved on the first connecting member 31. Figure 5 As shown, when the first connector 31 is fixed to the first structure, the first annular portion 41 is located above the upper surface of the first structural member 1, and the second annular portion 42 can be located below the lower surface of the first structural member 1. At least a portion of the second annular portion 42 can also abut against the lower surface of the first structural member 1. Optionally, both the first annular portion 41 and the second annular portion 42 can be circular ring structures.

[0036] The first annular portion 41 and the second annular portion 42 are spaced apart along the axial direction of the rotating member 4, and a mounting position for mounting the second structural member 2 is formed between the first annular portion 41 and the second annular portion 42. In use, the second structural member 2 can be placed between the first annular portion 41 and the second annular portion 42, which can initially limit the position of the second structural member 2 and improve the stability of the connection between the first structural member 1 and the second structural member 2.

[0037] In some specific embodiments, the first annular portion 41 is formed with a crimping portion 411, which can be a protrusion formed on the outer side of the first annular portion 41. A snap-fit ​​portion 43 is formed between the crimping portion 411 and the second annular portion 42. The crimping portion 411 is used to abut against the second structural member 2 when the rotating member 4 rotates to the first position. In this embodiment, the crimping portion 411 and the second annular portion 42 can clamp the first structural member 1 and the second structural member 2. Through the interaction between the crimping portion 411 and the second annular portion 42, the first structural member 1 and the second structural member 2 can be connected together. Optionally, at least one of the crimping portion 411 and the second annular portion 42 is elastic. When the rotating member 4 is rotated, it is necessary to overcome the elastic force of the crimping portion 411 or the second annular portion 42 so that the first structural member 1 and the second structural member 2 are located between the crimping portion 411 and the second annular portion 42. When the rotating member 4 is rotated to the first position, the first structural member 1 and the second structural member 2 can be fixed together under the action of the elastic restoring force of the crimping portion 411 or the second annular portion 42.

[0038] The first position corresponds to the position of the snap-fit ​​part 43. When the rotating member 4 rotates to the point where it can no longer rotate and the first structural member 1 and the second structural member 2 are located between the crimping part 411 and the second annular part 42, the rotating member 4 is in the first position.

[0039] In some specific embodiments, the crimping portion 411 is formed with a guide surface 411a. When the rotating member 4 is rotated, the second structural member 2 can enter the snap-fit ​​portion 43 formed between the crimping portion 411 and the second annular portion 42 along the guide surface 411a, thereby connecting the first structural member 1 and the second structural member 2 together.

[0040] In some specific embodiments, the first connecting member 31 is provided with a first boss, and a first limiting part and a second limiting part are formed on the outer side of the first boss. The first limiting part and the second limiting part are spaced apart along the circumference of the first boss. A mating part is formed on the inner side of the second annular part 42. The mating part mates with one of the first limiting part and the second limiting part. When the mating part mates with the first limiting part, the rotating member 4 rotates to the first position. When the mating part mates with the second limiting part, the rotating member 4 rotates to the second position. When the mating part mates with the first limiting part or the second limiting part, the rotating member 4 is fixed relative to the first connecting member 31, which can improve the stability of the connection between the first structural member and the second structural member 2. In this embodiment, the second annular part 42 can be elastic. When the rotating member 4 switches between the first position and the second position, the second annular part 42 can undergo elastic deformation. When the mating part mates with the first limiting part or the second limiting part, the elastic restoring force of the second annular part 42 can fix the rotating member 4 relative to the first connecting member 31.

[0041] It should be noted that when the rotating member 4 rotates to the second position, the second structural member 2 disengages from the locking part 43. That is to say, the second position is the position where the second structural member 2 is separated from the locking part 43.

[0042] Optionally, when the first limiting part and the second limiting part are grooves, the mating part is a protrusion; when the first limiting part and the second limiting part are protrusions, the mating part is a groove.

[0043] In some specific embodiments, the first connecting member 31 is provided with a second boss 311, the outer surface of the second boss 311 is formed with a first toothed structure 311a, and the inner surface of the second annular portion 42 is formed with a second toothed structure 422, the second toothed structure 422 engaging with the first toothed structure 311a. In this embodiment, the second annular portion 42 may be elastic. When the rotating member 4 switches between the first position and the second position, the second annular portion 42 may undergo elastic deformation. When the second toothed structure 422 transitions from the first tooth of the first toothed structure 311a to the next tooth of the first toothed structure 311a, the elastic restoring force of the second annular portion 42 can fix the rotating member 4 relative to the first connecting member 31.

[0044] In some specific embodiments, the rotating member 4 is made of an elastic material. The rotating member 4 can rotate relative to the first connecting member 31 by overcoming the elastic force. After the rotation is completed, the rotating member 4 can be fixed relative to the first connecting member 31 under the action of the elastic restoring force.

[0045] In some specific embodiments, the rotating member 4 includes a toggle part 44, which is connected to at least one of the first annular part 41 and the second annular part 42. In this embodiment, by driving the toggle part 44, the rotating member 4 can be switched between a first position and a second position, which facilitates the installation and disassembly of the second structural member 2 and the first structural member 1.
