Description

Technical Field

[0001] The present disclosure relates to the technical field of component fixing structures of electronic equipment, and in particular to a tool-free disassembly and assembly structure and electronic equipment. Background Art

[0002] At present, the solid-state drive (SSD) on the PCB motherboard in electronic devices needs to be equipped with a corresponding solid-state drive heat sink (SSD Heatsink) to dissipate the heat of the working solid-state drive to ensure the stability of the solid-state drive. In the current existing scheme, the fixing structure of the SSD heat sink and the fixing structure of the SSD are independently designed. Specifically, the SSD heat sink is fixed by the built-in screws and the studs welded on the PCB motherboard. When the SSD heat sink needs to be disassembled, the screws need to be removed with a screwdriver to remove the SSD heat sink. As for the solid-state drive, it needs to be equipped with a disassembly structure, which is fixed in the opening on the PCB board, so that the SSD is fixed by the disassembly structure.

[0003] The disadvantage of the above solution is that when the user replaces the SSD, he needs to remove the SSD heat sink with a screwdriver before removing the SSD disassembly structure, thereby removing the solid-state drive SSD. This operation is relatively complicated; and due to the large number of PCB openings, the stud holes for fixing the SSD heat sink and the openings for fixing the disassembly structure will increase the difficulty of layout. In addition, the SSD heat sink also adds a C-shaped ring to fix and prevent the screws from being lost, and the motherboard also needs to weld the studs for locking the screws, which is costly. And because the screw holes cannot be seen when locking the SSD heat sink, there is a risk of damaging the studs when blind locking.

[0004] Therefore, it is necessary to design a tool-free disassembly structure shared by an SSD heat sink and a solid-state drive SSD, so as to realize tool-free disassembly of the SSD heat sink and the solid-state drive SSD. Summary of the invention

[0005] The present disclosure provides a tool-free disassembly and assembly structure and an electronic device to at least solve one of the technical problems existing in the prior art.

[0015] In one possible implementation manner, a guiding slope is formed on the second end portion of the main body toward the slot, so that the card to be fixed is engaged in the slot under the guidance of the guiding slope.

[0016] In one possible implementation manner, a first end of the second engaging portion is connected to the main body portion, and a second end forms a hook portion, and the hook portion is used for engaging and connecting to a mounting slot of the heat sink.

[0017] In one possible implementation manner, it also includes an unlocking hook portion, which is connected to the second locking portion and is arranged close to the hook portion. The unlocking hook portion is used to drive the hook portion to separate from the radiator under the action of external force to release the fixation of the hook portion to the radiator.

[0043] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0044] According to one embodiment of the present disclosure, Figure 1-3 As shown, the present invention provides a tool-free disassembly and assembly structure 1 (referred to as "disassembly and assembly structure"), comprising:

[0045] Main body 11;

[0046] An elastic fixing portion 12 connected to the first end of the main body 11, and the elastic fixing portion 12 is used to be detachably connected to the mounting hole 21 of the PCB board 2;

[0047] A first engaging portion 13 is formed at the second end of the main body 11, and the first engaging portion 13 is used for engaging and connecting with the card 3 to be fixed;

[0048] The second engaging portion 14 is connected to the main body 11 , and is used for engaging and connecting with the heat sink 4 to be fixed.

[0049] For example, the main body 11 is generally cylindrical, and the elastic fixing portion 12 has elastic reset capability and can be detachably connected to the mounting hole 21, such as by snapping the two together. The card to be fixed 3 includes but is not limited to a solid state drive (SSD), and the corresponding heat sink of the card to be fixed is an SSD heat sink.

[0050] In the present application, the card to be fixed 3 and its heat sink 4 are fixed on the same tool-free disassembly and assembly structure at the same time, which has a simple structure, is easy to install and does not require tools for disassembly, thereby improving the installation and disassembly efficiency of the card to be fixed 3 and its heat sink 4 and improving user satisfaction.

[0051] In the present application, since only one disassembly and assembly structure 1 is needed to simultaneously fix the card 3 to be fixed and its heat sink 4, when the disassembly and assembly structure 1 is connected to the PCB board 2, the number of mounting holes 21 on the PCB board 2 is reduced, and the difficulty of layout and routing of the PCB board 2 is reduced. In addition, in the present application, the disassembly and assembly structure 1 can reduce the number of screws, plastic parts, etc., saving production costs. There is currently no similar solution in the industry, which can be used as a product selling point to provide users with a more convenient design solution.

[0052] In one embodiment, Figure 3As shown, the elastic fixing portion 12 is a buckle structure, which is penetrated and connected to the mounting hole 21 and forms a pressing force on the mounting hole 21 , so that the buckle structure is fixed on the mounting hole 21 .

[0053] For example, the elastic fixing portion 12 has elastic restoring capability, and for example, the elastic fixing portion 12 can be made of materials such as plastic and rubber.

[0054] For example, the snap-fit ​​structure includes a first side wing 121, a second side wing 122 and a connecting portion 123, the first side wing 121 and the second side wing 122 are distributed on both sides of the connecting portion 123 and the first ends of the three are connected, the second end of the connecting portion 123 is connected to the first end of the main body 11, and the second ends of the first side wing 121 and the second side wing 122 are used to press against the mounting hole 21 of the PCB board 2.

[0055] The elastic fixing part 12 is set as a buckle structure, and the buckle structure is connected with the mounting hole 21 of the PCB board 2 by two side wings. Therefore, when the disassembly structure 1 needs to be installed with the PCB board 2, it is only necessary to squeeze the first side wing 121 and the second side wing 122 to make the buckle structure pass through the mounting hole 21 of the PCB board, and then press the second end portions of the first side wing 121 and the second side wing 122 against the mounting hole 21.

[0056] Further, such as Figure 1-3 , Fig.11 As shown, in order to facilitate the first side wing 121 and the second side wing 122 to pass through the mounting hole 21 and the second end to press against the mounting hole 21, a plurality of steps are formed on the outer sides of the second ends of the first side wing 121 and the second side wing 122, and these steps are arranged along the length direction of the first / second side wing, so that when the first side wing 121 and the second side wing 122 gradually pass through the mounting hole 21, these steps gradually pass through the mounting hole one by one, and the first side wing and the second side wing gradually open automatically. Finally, after being installed in place, the steps at the second end portions of the first side wing 121 and the second side wing 122 press against the mounting hole 21 to form an undercut to prevent falling off. The first side wing 121 and the second side wing 122 form an extrusion force on the mounting hole 21 to further limit the vertical displacement of the PCB board 2. At this time, the first end portion of the main body presses against the upper surface of the mounting hole, so that the snap structure-the elastic fixing portion 12 can be firmly connected with the mounting hole 21 of the PCB board 2.

[0057] Of course, the elastic fixing portion 12 may also be arranged such that the first side wing 121 and the second side wing 122 completely pass through the mounting hole 21 and the second end portion is pressed against the bottom surface near the mounting hole of the PCB board 2, forming an undercut structure to prevent falling off and limit the vertical displacement of the PCB, which can also achieve a stable connection between the elastic fixing portion 12 and the PCB board 2.

[0058] Of course, the elastic fixing part 12 can also be an elastic clamping claw structure. After the clamping claw structure is squeezed inward to pass through the mounting hole 21, the protrusion provided at the end of the clamping claw structure presses against the mounting hole, which can also realize the detachable snap-in connection between the elastic fixing part and the mounting hole of the PCB board.

[0059] Further, such as Figure 3 As shown, the tool-free disassembly and assembly structure 1 of the present application further includes a positioning portion 15 , which is connected to the main body 11 , and is used to position the elastic fixing portion 12 when it is installed on the mounting hole 21 .

[0060] When the mounting hole 21 on the PCB board 2 is blocked by other components, or it is inconvenient to confirm whether the installation orientation is correct during installation; therefore, the mounting hole 21 on the PCB board is set to an irregular shape, such as Figure 4 As shown, the mounting hole 21 is generally T-shaped. Accordingly, a positioning portion 15 is provided in the disassembly and assembly structure 1 of the present application. The positioning portion 15 extends from the connection portion 123 of the elastic fixing portion 12 toward the main body 11. The positive projection shape of the structure formed by connecting the positioning portion 15, the connection portion 123 and the main body 11 is adapted to the shape of the mounting hole. Therefore, the provision of the positioning portion 15 limits the disassembly and assembly structure 1 to only be able to install the elastic fixing portion 12 and the mounting hole 21 in a specific installation direction, plays a positioning role in the installation of the elastic fixing portion 12, and prevents the installation direction from being wrong; thereby improving the installation efficiency of the disassembly and assembly structure 1.

[0061] In one embodiment, the first engaging portion 13 is a slot provided at the second end of the main body 11 , and the slot is used for engaging and connecting with the card 3 to be fixed.

[0062] like Figure 1-3 As shown, the card slot is opened along the circumferential direction of the second end of the main body 11. The card slot is generally in a circular ring shape. Taking the card 3 to be fixed as a solid state hard disk as an example, the free end of the card 3 to be fixed has a bayonet 31, and the other end corresponding to the free end is connected to the connector 5, and the connector 5 is installed on the PCB board 2. After the other end of the card 3 to be fixed is connected to the connector 5, the free end of the card 3 to be fixed is pressed down so that the bayonet 31 of the free end of the card 3 to be fixed is engaged in the card slot.

[0063] Furthermore, a guiding inclined surface 111 is formed at the second end of the main body 11 toward the card slot, so that the card 3 to be fixed can be engaged in the card slot under the guidance of the guiding inclined surface 111 .

[0064] For example, Figure 1-2As shown, the shape of the guide slope 111 is generally C-shaped. The guide slope 111 is connected to the card slot, and the guide slope 111 is inclined toward the card slot. When the free end of the card 3 to be fixed is pressed down, the free end of the card 3 to be fixed first abuts against the guide slope 111, and the main body 11 is pressed outward. The main body 11 is slightly deformed under the pressure of the card 3 to be fixed. The card 3 to be fixed is pressed downward continuously, and the free end of the card 3 to be fixed continues to move downward under the guidance of the guide slope 111 until the bayonet 31 is engaged in the card slot, and the main body 11 is automatically reset.

[0065] Therefore, when the card 3 to be fixed is installed downward, the main body 11 will be elastically deformed until the free end of the card 3 to be fixed is engaged in the card slot, and then the main body 3 automatically resets. Therefore, the main body 11 has elastic reset capability, and the main body 11 can be made of materials such as plastic and rubber.

[0066] In one embodiment, Figure 1-2 , Fig. 9 As shown, a first end of the second engaging portion 14 is connected to the main body 11 , and a second end forms a hook portion 16 . The hook portion 16 is used for engaging and connecting to the mounting slot 41 of the heat sink 4 .

[0067] For example, after the card to be fixed 3 is engaged in the first engaging portion 13, a heat conducting member ( Figure 6-8 , Fig.11 (not shown), for example, the heat conducting member is a silicone paste, so that the heat sink 4 and the card to be fixed 3 are in close contact to conduct heat, and the heat sink 4 is used to dissipate heat from the card to be fixed 3. Figure 1-3 As shown, the second engaging portion 14 is a strip-shaped structure, and the hook portion 16 is arranged above the first engaging portion 13. The cross-sectional shape of the hook portion 16 is a triangle. Specifically, the bottom of the hook portion 16 forms a flat engaging surface 141, and the top of the hook portion 16 forms an inclined surface, which also has a guiding function. When the radiator 4 needs to be installed, the two ends of the radiator 4 first contact with the top inclined surface of the hook portion 16, and the radiator 4 continues to be pressed downward and under the guidance of the top inclined surface of the hook portion 16, the second engaging portion 14 interferes and deforms until it is assembled in place, and the second engaging portion 14 automatically resets, and the engaging surface 141 at the bottom of the hook portion 16 is pressed on the installation groove 41; at this time, the radiator 4 is in close contact with the card 3 to be fixed, and the hook portion forms a vertical downward pressing force on the radiator 4.

[0068] Among them, because the second engaging portion 14 will be elastically deformed under the downward pressure of the radiator 4 and can automatically reset after the radiator is installed in place, the second engaging portion 14 has elastic reset capability and can be made of materials such as plastic and rubber.

[0069] For example, Figure 1-3 As shown, the tool-free disassembly and assembly structure of the present application also includes an unlocking hook portion 17, which is connected to the second locking portion 14 and is arranged close to the hook portion 16. The unlocking hook portion 17 is used to drive the hook portion 16 to separate from the radiator 4 under the action of external force to release the fixation of the hook portion 16 to the radiator 4.

[0070] The unlocking hook portion 17 is generally a bent strip structure, and the unlocking hook portion 17 is connected to the second engaging portion 14, and the connection position of the two is arranged close to the hook portion 16. When the radiator 4 needs to be disassembled, the unlocking hook portion 17 is manually pushed outward, so that the unlocking hook portion 17 drives the hook portion 16 to be separated from the mounting groove 41 of the radiator 4, thereby releasing the fixing of the hook portion 16 to the radiator 4.

[0071] In one embodiment, the tool-free disassembly and assembly structure of the present application also includes an elastic arm clamping portion 18 with elastic reset capability, and the first end of the elastic arm clamping portion 18 is connected to the main body 11; when the elastic fixing portion 12 is detachably connected to the mounting hole 21 of the PCB board 2, the second end of the elastic arm clamping portion 18 is interference-connected to the PCB board 2.

[0072] like Figure 1-3 As shown, the elastic arm clamping part 18 is generally an arc-shaped structure, the first end of the elastic arm clamping part 18 is connected to the main body 11, and the second end of the elastic arm clamping part 18 presses on the PCB board 2. When the elastic fixing part 12 of the disassembly structure 1 is installed on the mounting hole 21 of the PCB board 2, the elastic arm clamping part 18 presses on the PCB board, and the elastic arm clamping part 18 elastically deforms to form a downward pressing force on the PCB board 2, so that the PCB board 2 is clamped between the elastic arm clamping part 18 and the elastic fixing part 12 of the disassembly structure 1 and prevents the disassembly structure 1 from tipping over, thereby the elastic arm clamping part 18 can play the role of clamping and preventing tipping over.

[0073] The so-called interference connection means that when the elastic fixing part 12 of the disassembly structure 1 is installed on the mounting hole 21, the elastic arm clamping part 18 undergoes elastic deformation compared to the free state, thereby forming a downward pressing force on the PCB board 2.

[0074] Furthermore, the disassembly and assembly structure 1 of the present application is an integrated structure consisting of a main body 11, an elastic fixing part 12, a first clamping part 13, a second clamping part 14, a positioning part 15, an unlocking hook part 17 and an elastic arm clamping part 18. The integrated structure is simple, convenient and easy to manufacture.

[0075] For example, the disassembly structure 1 is integrally formed by injection molding of a mold, and the material of the disassembly structure 1 can be plastic, rubber, etc., so that the disassembly structure 1 is a plastic part with elastic reset capability.

[0076] According to one embodiment of the present disclosure, Figure 4-11As shown, the present invention further provides an electronic device, comprising a PCB board 2, a card to be fixed 3, and a heat sink 4 for dissipating heat from the card to be fixed 3, and also comprising the tool-free disassembly and assembly structure 1 in any one of the above embodiments;

[0077] The PCB board 2 is provided with a mounting hole 21, and the mounting hole 21 is detachably connected to the elastic fixing portion 12, so that the tool-free disassembly structure 1 is fixed on the PCB board 2;

[0078] The free end of the card to be fixed 3 has a bayonet 31, and the bayonet 31 is engaged with the first engaging portion 13;

[0079] The heat sink 4 has mounting grooves 41 at both ends, and the mounting grooves 41 are engaged with the second engaging portion 14 .

[0080] In the present application, the electronic device with the disassembly structure 1 can also realize that the card to be fixed 3 and its heat sink 4 can be fixed on the same tool-free disassembly structure at the same time. It has a simple structure, is easy to install and does not require tools for disassembly, thereby improving the installation and disassembly efficiency of the card to be fixed 3 and its heat sink 4 and enhancing user satisfaction.

[0081] For example, the card 3 to be fixed includes but is not limited to a solid state hard disk, and the corresponding heat sink is a solid state hard disk heat sink.

[0082] The installation of the disassembly structure 1, the PCB board 2, the card to be fixed 3 and the heat sink 4 is described as follows: Figure 4-5 As shown, a card to be fixed 3 and a heat sink 4 are fixed by two disassembly structures 1, and the two disassembly structures are respectively installed in the mounting holes 21 of the PCB board on the left and right sides of the connector 5, and the elastic fixing part 12 of the disassembly structure 1 passes through the mounting hole 21, so that the elastic fixing part 12 is engaged and fixed on the mounting hole 21. Figure 6 As shown, one end of the card 3 to be fixed is plugged and connected to the connector 5 on the PCB board, and the free end of the card 3 to be fixed is abutted against the guide slope 111 of the second end of the main body 11, and then the card 3 to be fixed is pressed down, and is pressed down under the guidance of the guide slope 111 until it is stuck in the card slot (first clamping portion 13). At this time, the card 3 to be fixed is fixed on the disassembly structure 1 and the connector 5, as shown in FIG. Figure 7 shown.

[0083] like Figure 8-11 As shown, the two ends of the radiator 4 are then abutted against the second end (hook portion 16) of the second engaging portion 14, and under the guidance of the top inclined surface of the hook portion 16, the radiator 4 is pressed downward to cause the hook portion 16 to interfere and deform until it is assembled into place, and the hook portion 16 is reset and fixed on the mounting groove 41 of the radiator 4. At this time, the second end of the main body 11 is accommodated in the avoidance groove 42 opened in the radiator 4, and the radiator 4 is pressed against the card 3 to be fixed.

[0084] The disassembly process of the installed heat sink 4 and the card 3 to be fixed is described as follows:

[0085] First, press the unlocking hook portion 17 outward, and the unlocking hook portion 17 drives the hook portion 16 to disengage from the mounting slot 41 of the radiator 4; then remove the radiator 4; and then push outward with the guide slope 111 as the force point to plastically deform the main body 11, so that the slot is disengaged from the free end of the card 3 to be fixed, and the card 3 to be fixed automatically pops up by the force of the connector 5, so that the card 3 to be fixed can be replaced without tools; finally, if the disassembly structure 1 needs to be further disassembled, the two side wings of the elastic fixing portion 12 can be squeezed to disengage the elastic fixing portion 12 from the mounting hole 21 of the PCB board, thereby easily disassembling the disassembly structure 1.
