Description

Technical Field

[0001] This utility model relates to the field of electronic device technology, and in particular to a hard disk fixing device and an electronic device. Background Technology

[0002] SSDs are a type of NAND flash memory with higher capacity integration. Thanks to the rapid development of PCs, SSDs have also seen rapid advancements in transfer speeds, evolving from SATA to PCIe interfaces.

[0003] In related technologies, the mounting method of strip-shaped SSDs (commonly with M.2 or enterprise-grade E1.s interfaces) on a circuit board generally consists of three parts: 1. Connector; 2. SSD storage unit; 3. Tail-end fixing component. The connector is soldered onto the PCB, and the SSD's gold fingers insert into the connector. A groove in the middle of the SSD's tail connects to a stud, which is then secured with a screw. The connection between the stud and the PCB has poor stability. The fixing component consists of a stud and a screw. When connecting the stud to the PCB, a hole design is required to ensure torque. The screws also transmit torque when fixing the SSD. When applied to automotive electronic devices, there are long-term vibration scenarios with varying frequencies, and this mounting method leads to screw torque attenuation, potentially causing the SSD to fall out. The disassembly and assembly process requires a screwdriver, involving unnecessary and cumbersome steps. Utility Model Content

[0036] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0037] The following is for reference. Figures 1-6 The present invention describes a hard disk fixing device 100 according to an embodiment of the present invention, and also proposes an electronic device including the above-described hard disk fixing device 100.

[0038] Notice: Figures 1-6 In the diagram, the first direction is the same as the width direction of the hard disk 300, the second direction is the same as the length direction of the hard disk 300, and the third direction is the thickness direction of the hard disk 300. Taking the third direction as the height direction, the side of the hard disk 300 away from the motherboard 200 is the top, and the side of the hard disk 300 facing the motherboard 200 is the bottom.

[0039] like Figures 3-6 As shown, the hard disk mounting device 100 is fixed to the motherboard 200. For example, the motherboard 200 can be an in-vehicle domain control board. The hard disk mounting device 100 is connected to the motherboard 200 and is used to fix the hard disk 300 to the motherboard 200. The hard disk 300 can be an SSD.

[0040] The hard disk mounting device 100 includes a base 10, a mounting assembly, and an elastic element 31. The other end of the hard disk 300 in the longitudinal direction is connected to a connector 400. The hard disk 300 is fixed to the motherboard 200 by connecting one end of the hard disk 300 in the longitudinal direction to the hard disk mounting device 100.

[0041] The mounting component is connected to the upper side of the base 10; the elastic element 31 is connected to the lower side of the base 10. The elastic element 31 is telescopic in the height direction and is located below the mounting component, defining an installation space for accommodating the hard drive 300. Specifically, both the elastic element 31 and the mounting component are connected to the base 10, with the mounting component located above the elastic element 31. The mounting component and the elastic element 31 define the installation space. One side of the hard drive 300 is connected to the connector 400, and the other side is inserted into the installation space to install the hard drive 300. After the hard drive 300 is installed, the elastic element 31 provides elastic support for the hard drive 300 and ejects the hard drive 300 during removal, improving the ease of removal.

[0042] When installing hard drive 300, one end of hard drive 300 is inserted into the installation space along its length. After insertion, the installation assembly limits the upper surface of elastic member 31, which abuts against the lower surface of hard drive 300. Elastic member 31 also applies an upward force to hard drive 300, securing it within the installation space and thus fixing one end of hard drive 300. Simply pressing down on hard drive 300 allows it to pop out under the action of elastic member 31, facilitating installation and removal.

[0043] Unlike existing technologies where multiple components are fixed to the motherboard 200 with screws, this invention only requires pre-soldering the hard drive mounting device 100 to the motherboard 200. No additional mounting components are needed for subsequent use, eliminating the problem of screw torque attenuation and improving the connection stability between the hard drive 300 and the motherboard 200. The hard drive mounting device 100 of this invention is easy and quick to install and remove. No screwdrivers or other tools are required during installation; simply press the rear of the hard drive 300 to secure it, and move the mounting component to automatically eject it during removal.

[0044] Compared to existing traditional screw fixing solutions, the hard drive fixing device 100 designed in this patent simplifies the installation components. The hard drive fixing device 100 can be welded to the motherboard 200. No extra tools are needed for the installation and removal of the hard drive 300. The hard drive 300 can be removed simply by pressing the elastic element 31.

[0045] The elastic element 31 includes a first part 311 and a second part 312. One end of the first part 311 is connected to the base 10, and the second part 312 is connected to the other end of the first part 311 and is bent relative to the first part 311. The first part 311 is inclined upward, and its lower end is connected to the base 10. The second part 312 is connected to the upper end of the first part 311 and is inclined downward relative to the first part 311, so that the connection between the first part 311 and the second part 312 abuts against the lower surface of the hard disk 300, providing elastic support for the hard disk 300.

[0046] like Figures 1-6 As shown, the installation assembly includes: a first fixing member 21, which is disposed on one or both sides of the base 10 in a first direction. A first fixing part 211 is provided on the lower side of the first fixing member 21, and the first fixing part 211 abuts against the upper surface of the hard disk 300 to limit one or both sides of the hard disk 300 in the width direction. Specifically, the first fixing member 21, disposed on one or both sides of the base 10 in a first direction, can position the hard disk 300 in the width direction during installation, improving the installation efficiency of the hard disk 300. The first fixing part 211 on the first fixing member 21 abuts against the upper surface of the hard disk 300 after the hard disk 300 is inserted into the installation space, limiting the upper side of the hard disk 300 and preventing the hard disk 300 from being ejected under the elastic force of the elastic member 31.

[0047] In some embodiments, the first fixing member 21 can be a single unit. The first fixing member 21 is disposed on one side of the base 10 in the first direction to limit the upper surface of the hard disk 300 and prevent the hard disk 300 from popping out after installation. At the same time, the first fixing member 21 limits one side of the width direction of the hard disk 300, which facilitates the installation and positioning of the hard disk 300.

[0048] In some other embodiments, there may be two first fixing members 21, which are respectively disposed on both sides of the base 10 in the first direction to limit the upper surface of the hard disk 300 and prevent the hard disk 300 from popping out after installation; at the same time, the first fixing members 21 can limit both sides of the width direction of the hard disk 300, and facilitate the installation and positioning of the hard disk 300.

[0049] In some embodiments, the first fixing member 21 is provided with a first guide slope 212 on the side that contacts the hard disk 300. The first guide slope 212 is inclined upward toward the side away from the hard disk 300. When installing or removing the hard disk 300, the first guide slope 212 can guide the hard disk 300, thereby improving the efficiency of installation and removal.

[0050] like Figure 2 and Figure 4 As shown, the first fixing part 211 is a first limiting step, which limits the hard disk 300 on one or both sides in the width direction. Specifically, when the hard disk 300 is inserted into the installation space, the first limiting step can abut against the upper surface of the hard disk 300, limiting the upper side of the hard disk 300 and preventing the hard disk 300 from being ejected under the elastic force of the elastic member 31. The first limiting step can position the hard disk 300 in the width direction during installation, improving the installation efficiency of the hard disk 300.

[0051] In some embodiments, the first fixing member 21 can be a single unit, namely, the base 10 is provided with a first limiting step on one side in the first direction, the first limiting step abuts against the upper surface of the hard disk 300 to prevent the hard disk 300 from popping out after installation; at the same time, the first fixing member 21 limits one side of the hard disk 300 in the width direction, and facilitates the installation and positioning of the hard disk 300.

[0052] In some other embodiments, there may be two first fixing members 21, which are respectively disposed on both sides of the base 10 in the first direction to limit the upper side of the hard disk 300 and prevent the hard disk 300 from popping out after installation; at the same time, the first fixing members 21 can limit both sides of the width direction of the hard disk 300, and facilitate the installation and positioning of the hard disk 300.

[0053] Furthermore, the mounting assembly also includes a second fixing member 22, which is disposed on one side of the base 10 in the second direction. A second fixing part 221 is provided on the lower side of the second fixing member 22, and the second fixing part 221 can abut against the upper surface of the hard disk 300 to limit one side of the hard disk 300 in the length direction. Specifically, the second fixing member 22 is disposed on one side of the base 10 in the second direction, and can cooperate with the connector 400 to limit and fix the hard disk 300 in the length direction. The connector 400 limits the hard disk 300 on the other side in the length direction, and the second fixing member 22 limits the hard disk 300 on the other side in the length direction. The second fixing member 22 is provided with a second fixing part 221. The second fixing part 221 is located below the second fixing member 22. After the hard disk 300 is inserted into the installation space, the second fixing part 221 abuts against the upper surface of the hard disk 300. The second fixing part 221 can limit the hard disk 300 in the height direction to prevent the hard disk 300 from popping out of the installation space and ensure the installation reliability of the hard disk 300.

[0054] In some embodiments, the second fixing member 22 is provided with a second guide slope 222 on the side that contacts the hard disk 300. The second guide slope 222 is inclined upward toward the side away from the hard disk 300. When installing or removing the hard disk 300, the second guide slope 222 can guide the hard disk 300, thereby improving the efficiency of installation and removal.

[0055] Combination Figure 2 and Figure 4As shown, the second fixing part 221 is a second limiting step, which limits the upper surface of the hard disk 300 on one side in the length direction. Specifically, when the hard disk 300 is inserted into the installation space, the second limiting step can abut against the upper surface of the hard disk 300 on one side in the length direction, limiting the upper side of the hard disk 300 and preventing the hard disk 300 from being ejected under the elastic force of the elastic member 31. The first limiting step can position the hard disk 300 in the width direction during installation, improving the installation efficiency of the hard disk 300.

[0056] Furthermore, the first fixing member 21 is a spring clip. Specifically, the first fixing member 21 can be a spring clip with elasticity. When installing the hard drive 300, the hard drive 300 is pressed into the installation space, and the first fixing member 21 tilts outward under the pressure, making it easier for the hard drive 300 to be inserted into the installation space; when removing the hard drive 300, the first fixing member 21 is moved to release the first fixing part 211 from the hard drive 300, and the hard drive 300 can automatically pop out under the action of the elastic member 31.

[0057] In some other embodiments, the second fixing member 22 is a spring clip. Specifically, the second fixing member 22 can be a spring clip with elasticity. When installing the hard disk 300, the hard disk 300 is pressed into the installation space, and the second fixing member 22 tilts outward under the pressure, making it easier for the hard disk 300 to be inserted into the installation space; when removing the hard disk 300, the second fixing member 22 is moved to release the second fixing part 221 from the hard disk 300, and the hard disk 300 can then automatically pop out under the action of the elastic member 31.

[0058] Therefore, the first fixing member 21 and the second fixing member 22 can limit and fix the short side and the long side of the hard disk 300. The first fixing member 21 and the second fixing member 22 are elastic sheets, which can effectively resist vehicle vibration attenuation when the hard disk 300 is installed on the vehicle domain control board.

[0059] like Figure 2 As shown, the hard disk mounting device 100 also includes a positioning component, which is connected to the lower side of the base 10. Specifically, the positioning component is used to abut against the lower surface of the hard disk 300. After the hard disk 300 is inserted into the installation space, the positioning component limits the lower surface of the hard disk 300. The height of the positioning component is kept consistent with the installation position height on the connector 400 to ensure the reliability of the hard disk 300 installation.

[0060] Further, the positioning component includes a first positioning member 41, located below the mounting component and on one or both sides of the base 10 in a first direction. The first positioning member 41 selectively abuts against the lower end of the hard disk 300. Specifically, the first positioning member 41 limits the minimum height at which the hard disk 300 is installed. The first positioning member 41 can abut against the lower surface of one or both sides of the hard disk 300 in the width direction. After the hard disk 300 is inserted into the installation space, the lower surface of the hard disk 300 abuts against the first positioning member 41. When the hard disk 300 is removed, the hard disk 300 does not abut against the first positioning member 41.

[0061] In some embodiments, the first positioning member 41 can be one, that is, the base 10 is provided with a first positioning member 41 on one side in the first direction. One first positioning member 41 is correspondingly provided with one first fixing member 21. The first fixing member 21 limits the upper surface of the hard disk 300 on one side in the width direction, and the first positioning member 41 limits the lower surface of the hard disk 300 on one side in the width direction. The first positioning member 41 abuts against the lower surface of the hard disk 300 to prevent the hard disk 300 from contacting the motherboard 200 and causing a short circuit, etc.

[0062] In some other embodiments, there may be two first positioning members 41, which are respectively disposed on both sides of the base 10 in the first direction. The two first positioning members 41 are correspondingly disposed with two first fixing members 21. The first fixing members 21 limit the upper surface of the hard disk 300 on both sides in the width direction, and the first positioning members 41 limit the lower surface of the hard disk 300 on both sides in the width direction. The first positioning members 41 abut against the lower surface of the hard disk 300 to prevent the hard disk 300 from contacting the motherboard 200 and causing a short circuit, etc.

[0063] Furthermore, the positioning assembly also includes a second positioning member 42, which is located below the mounting assembly and on one side of the base 10 in the second direction. The second positioning member 42 selectively abuts against the lower end of the hard disk 300. Specifically, the second positioning member 42 is located below the mounting assembly and abuts against the lower surface of the hard disk 300 on one side in the length direction. The height of the second positioning member 42 is the same as that of the first positioning member 41. After the hard disk 300 is inserted into the installation space, the lower surface of the hard disk 300 abuts against the second positioning member 42, limiting the minimum installation height of the hard disk 300.

[0064] In some embodiments, the height of the first positioning member 41 and the second positioning member 42 is H1, the distance between the first fixing part 211 and the second fixing part 221 and the motherboard 200 is H2, the thickness of the hard disk 300 is A, and H1 and H2 satisfy the relationship: H2-H1<A. Specifically, the first positioning member 41 and the first fixing part 211 abut against the lower surface and the upper surface of the hard disk 300, respectively. The second positioning member 42 and the second fixing part 221 abut against the lower surface and the upper surface of the hard disk 300, respectively. The distance between the first positioning member 41 and the first fixing part 211 is less than the thickness of the hard disk 300, and the distance between the second positioning member 42 and the second fixing part 221 is less than the thickness of the hard disk 300. Since the first fixing member 21 and the second fixing member 22 have elastic deformable characteristics, the hard disk 300 can be accommodated between the first positioning member 41 and the first fixing member 21, and between the second positioning member 42 and the second fixing member 22. The first fixing member 21 and the first positioning member 41 play the role of clamping one or both sides of the hard disk 300 in the width direction, and the second fixing member 22 and the second positioning member 42 play the role of clamping one end of the hard disk 300 in the length direction, ensuring the installation reliability of the hard disk 300 and effectively increasing the stability of the hard disk 300. The hard drive 300 can be an SSD, which can enable reliable application of in-vehicle SSDs when used in vehicles.

[0065] In some embodiments, the elastic member 31 is telescopic in the height direction. The upper stroke of the elastic member 31 is H3, and the lower stroke of the elastic member 31 is H4. H3 and H4 satisfy the following relationship: H3 > H2; H2 > H4. Specifically, the upper stroke of the elastic member 31 is the distance from the upper surface of the elastic member 31 to the motherboard 200 in its natural state, and the lower stroke of the elastic member 31 is the distance from the upper surface of the elastic member 31 to the motherboard 200 when the elastic member 31 is compressed to its shortest length. The upper stroke must be greater than the distance from the first fixing part 211 and the second fixing part 221 to the motherboard 200, and the lower stroke must be less than the height of the first positioning member 41 and the second positioning member 42, so that the installation and removal of the hard drive 300 are smooth and convenient.

[0066] like Figure 1 and Figure 2 As shown, there are two elastic elements 31, which are symmetrically arranged along the first direction. Specifically, the two elastic elements 31 are respectively connected to the two sides of the base 10 in the first direction. The two elastic elements 31 are symmetrically arranged along the first direction, which provides support for the two sides of the hard disk 300 in the width direction, ensuring stable support for all parts of the hard disk 300.

[0067] like Figure 1 and Figure 2As shown, the hard disk mounting device 100 also includes: solder pads 32, which are connected to the motherboard 200 and the base 10. Specifically, there can be multiple solder pads 32, which are connected to the motherboard 200 and to the positioning components. The hard disk 300 can connect to the solder pads 32 by abutting against the positioning components, thereby achieving grounding.

[0068] An electronic device according to a second aspect embodiment of the present invention includes: a motherboard 200, a connector 400 mounted on the motherboard 200, and a hard disk mounting device 100 mounted on the motherboard 200. The hard disk mounting device 100 cooperates with the connector 400 to mount a hard disk 300. One end of the hard disk 300 is inserted into an installation space, and the other end of the hard disk 300 is connected to the connector 400. The hard disk 300 mounting clip designed in this scheme has no screws or nuts, eliminating the need for drilling holes in the motherboard 200 for installation. The hard disk mounting device 100 is fixed to the motherboard 200 by welding, reducing the number of connection points and improving the stability of the hard disk 300. The installation and removal of the hard disk 300 do not require screwdrivers; only pressing is needed, making production and maintenance quick and convenient, and improving efficiency.

[0069] Instructions for the installation and removal of the hard disk mounting device 100 on the hard disk 300.

[0070] Step 1: Solder the connector 400 and hard drive mounting device 100 onto the motherboard 200. When laying out the motherboard 200, the silkscreen markings for the package and the corresponding pad 32 should be established according to the length specifications of the hard drive 300.

[0071] Step 2: Connect the gold finger part of the hard drive 300 to the connector 400. The angle between the other side of the hard drive 300 and the gold finger should be between 10° and 15°.

[0072] Step 3: Align the tail of the hard drive 300 vertically with the limiting groove formed by the base 10 of the hard drive fixing device 100. Due to the elasticity of the first fixing member 21 and the second fixing member 22, the hard drive 300 will naturally lift up. Press the tail with your index finger or thumb. At this time, the second fixing member 22 will be pressed outward and the first fixing member 21 will be pressed to the sides. At the same time, the two elastic members 31 at the bottom will move downward.

[0073] When the hard drive 300 is lower than the first fixing part 211 and the second fixing part 221, the first fixing part 21 and the second fixing part 22 spring back, thus fixing the hard drive 300. Here, the lowest position where the hard drive 300 is pressed is the height position of the first positioning part 41 and the second positioning part 42. The overall effect after installation is shown in the figure below. Figure 3 As shown in the detailed rendering of the tail section... Figure 4 and Figure 5 .

[0074] Step 4: Disassembly of hard drive 300. Apply lateral force to the first fixing member 21 and outward force to the second fixing member 22. When the first fixing part 211 and the second fixing part 221 are separated from the edge of hard drive 300, hard drive 300 will be springed up by the elastic force of the two elastic members 31 at the bottom. Further, hard drive 300 can be removed and the gold fingers can be pulled out to complete the disassembly of hard drive 300.
