Description

Technical Field

[0001] The present application relates to the technical field of hard disk fixing, and in particular to a connection device between a hard disk and a motherboard. Background Art

[0002] In recent years, with the rapid development of Internet technology, especially the continuous breakthroughs in key technologies such as big data and cloud platforms, the demand for servers has continued to increase, and at the same time, the performance of server products, especially the hard disk response speed, has become increasingly demanding. The M.2 interface solid-state hard disk has the advantages of small size and fast response speed, making it more and more widely used. The M.2 hard disk can be stably and reliably fixed on the motherboard, which is the premise for the M.2 hard disk to play its advantages such as response speed. However, the existing M.2 hard disk is usually locked on the motherboard by screws, and the disassembly and assembly steps are cumbersome and time-consuming. Summary of the invention

[0003] Based on this, it is necessary to provide a connection device between a hard disk and a motherboard to solve the problem of quickly fixing and removing the hard disk.

[0004] A connection device between a hard disk and a mainboard, the connection device between the hard disk and the mainboard comprising:

[0005] Hard disk and motherboard;

[0006] A base having a receiving cavity, wherein the base is mounted on the main board;

[0007] A lifting component, one end of which is disposed in the accommodating cavity, and the other end of which is disposed outside the accommodating cavity;

[0008] A limiting member, connected to the lifting assembly and located outside the accommodating cavity;

[0009] The hard disk has a fixed state in which it is connected and locked with the mainboard, and an unlocked state in which it is unlocked with the mainboard. When in the fixed state, the lifting assembly is clamped on the wall of the accommodating cavity, and the limiting member is located on a separation path of the hard disk relative to the mainboard to prevent the hard disk from moving away from the mainboard; the lifting assembly is separated from the wall of the accommodating cavity, and the limiting member deviates from the separation path, so that the hard disk switches from the fixed state to the unlocked state, and the hard disk can be separated from the mainboard.

[0010] In the connection device between the hard disk and the motherboard, one end of the lifting component is located in the accommodating cavity of the base, and the other end is arranged outside the accommodating cavity, and a limiting member is arranged on the area outside the accommodating cavity of the lifting component. When the hard disk on the motherboard needs to be locked, that is, when the hard disk is in a fixed state, the lifting component is clamped on the cavity wall of the accommodating cavity, and the limiting member is located on the separation path of the hard disk relative to the motherboard, thereby blocking the hard disk from moving away from the motherboard. When the hard disk needs to be released, the lifting component is separated from the cavity wall of the accommodating cavity, and the limiting member is deviated from the separation path. At this time, the hard disk can be switched from the fixed state to the unlocked state, and the hard disk can be separated from the motherboard. The connection device between the hard disk and the motherboard provided in the present application is pressed on the separation path of the hard disk by the blocking member, thereby blocking the separation of the hard disk and the motherboard. The motherboard and the hard disk can be separated by only separating the lifting component from the cavity wall of the accommodating cavity and deviating the blocking member from the separation path.

[0011] In one embodiment, the lifting assembly is configured to move along a first direction to extend into the accommodating cavity, and the lifting assembly is configured to move along a second direction and then rotate around the second direction to make the limiting member deviate from the separation path, wherein the first direction and the second direction are opposite.

[0012] When the hard disk and the motherboard need to be locked, the lifting assembly is first moved in the first direction into the accommodating cavity, so that the lifting assembly is engaged with the cavity wall of the accommodating cavity, and then the limiting member is pressed against the hard disk, thereby limiting the relative position between the hard disk and the motherboard and limiting the movement of the hard disk. When the hard disk needs to be unlocked, the lifting assembly is first moved in the second direction to release the engaging relationship between the lifting assembly and the cavity wall of the accommodating cavity, and then the lifting assembly is rotated around the second direction, so that the limiting member on the lifting assembly is away from the hard disk and separated from the hard disk, so that the hard disk is switched from a fixed state to an unlocked state, which makes it easy to remove the hard disk from the motherboard. The connection device of the hard disk and the motherboard of the present application, when it is necessary to unlock the hard disk, it is only necessary to move the lifting component along the second direction and rotate it around the second direction to release the fixation of the hard disk; when it is necessary to limit the positional relationship between the hard disk and the motherboard, it is only necessary to move the lifting component along the first direction and then rotate the limiting member around the first direction so that the limiting member is pressed onto the hard disk, thereby limiting the relative position of the hard disk and the motherboard. The connection device of the hard disk and the motherboard of the present application is convenient for disassembly and assembly, thereby improving the disassembly and assembly efficiency.

[0013] In one embodiment, the lifting assembly includes a lifting shaft and a pressing shaft, the pressing shaft is sleeved on the lifting shaft, and the end of the lifting shaft extends out of the pressing shaft, the limiting member is connected to the pressing shaft, and when in the fixed state, the lifting shaft is clamped in the cavity wall of the accommodating cavity, the lifting shaft is configured to move along the second direction to separate the lifting shaft and the cavity wall of the accommodating cavity, and the lifting shaft and the pressing shaft are configured to move synchronously around the second direction to make the limiting member deviate from the separation path.

[0014] The pressure shaft is sleeved outside the lifting shaft, and the stopper is connected to the pressure shaft. The end of the lifting shaft extends outside the pressure shaft, that is, the end of the lifting shaft is exposed, so that the lifting shaft is conveniently engaged with the cavity wall of the accommodating cavity when in a fixed state. When it is necessary to separate the motherboard and the hard disk, the lifting shaft is first configured to move relative to the pressure shaft along the second direction to release the engagement between the lifting shaft and the cavity wall of the accommodating cavity, and then the lifting shaft and the pressure shaft are configured to rotate synchronously around the second direction, so that the stopper rotates around the second direction to separate from the hard disk.

[0015] In one of the embodiments, a protrusion is provided on the lifting shaft, a groove is provided on the cavity wall of the accommodating cavity, and an accommodating groove is provided on the end surface of the pressing shaft extending into the accommodating cavity; when in the fixed state, the protrusion is engaged with the groove, and when in the unlocked state, the protrusion is arranged in the accommodating groove.

[0016] A protrusion is provided on the lifting shaft, and a groove is provided on the cavity wall of the accommodating cavity. When the hard disk is in a fixed state, the protrusion is engaged with the groove, thereby limiting the relative position of the lifting assembly and the base. Because the base is installed on the mainboard, the relative position of the lifting assembly and the mainboard is also limited. When the protrusion is engaged with the groove, the lifting assembly is rotated at this time, so that the limiter is pressed on the hard disk, thereby fixing the hard disk. In addition, an accommodating groove is provided on the end surface of the pressing shaft extending into the accommodating cavity. When the lifting assembly is moved along the second direction, that is, when the lifting shaft is moved along the second direction, the protrusion on the lifting shaft moves along the second direction, disengages from the groove, and then engages in the accommodating groove. At this time, it means that the lifting assembly can be rotated around the second direction, which is convenient for subsequent unlocking actions.

[0017] In one of the embodiments, it further includes an elastic member disposed in the accommodating cavity, and the elastic member is used to push the lifting shaft to move along the first direction through its own elastic force.

[0018] By arranging an elastic member in the accommodating cavity, the elastic member pushes the lifting shaft to move in the first direction, so that the protrusion of the lifting shaft and the groove on the cavity wall of the accommodating cavity are correspondingly engaged, locking the lifting shaft to prevent the lifting shaft from moving in the second direction.

[0019] In one of the embodiments, the pressing shaft is provided with an annular boss located in the accommodating cavity, the elastic member is sleeved on the pressing shaft, and one end of the elastic member abuts against the annular boss and the other end abuts against the protrusion.

[0020] The elastic member is sleeved on the pressure shaft, and one end of the elastic member abuts against the annular boss, and the other end abuts against the protrusion. The function of the elastic member is to prevent the lifting shaft from being in a free state. If unlocking is required, the elastic force of the elastic member must be overcome to achieve the effect of preventing accidental touch. When the hard disk needs to be unlocked, the lifting shaft is first moved in the second direction. At this time, the elastic member will be compressed, so that the protrusion on the lifting shaft leaves the groove on the cavity wall of the accommodating cavity, and the protrusion enters the accommodating groove at the end of the pressure plate. At this time, the first unlocking step has been completed, and then the lifting assembly can be rotated to rotate the limit member connected to the pressure shaft away from the hard disk to complete the unlocking.

[0021] In one of the embodiments, a limiting groove for accommodating the end of the lifting shaft is provided on the cavity wall of the accommodating cavity.

[0022] A limiting groove is provided on the cavity wall of the accommodating cavity. When the hard disk is in a fixed state, that is, when the protrusion and the groove are correspondingly engaged, the exposed end of the lifting shaft can also be engaged with the limiting groove, thereby improving the engagement stability between the lifting assembly and the cavity wall of the accommodating cavity, and thus improving the fixing effect of the hard disk.

[0023] In one of the embodiments, the base includes a body and a cover plate, the body has the accommodating cavity, the cover plate is connected to the body to block the accommodating cavity, and the cover plate is provided with a through hole for the lifting assembly to pass through.

[0024] The main body is provided with a receiving cavity to receive the end of the lifting assembly, and a cover plate is provided to be connected to the main body to block the receiving cavity to prevent external dust and water droplets from flowing into the receiving cavity. A through hole is provided on the cover body to facilitate the end of the lifting assembly to pass through.

[0025] In one of the embodiments, a knob is further included, wherein the knob is connected to an end of the lifting assembly facing away from the base.

[0026] The knob is connected to the end of the lifting assembly facing away from the base, that is, the knob is connected to the end of the lifting assembly exposed outside the accommodating cavity. The lifting assembly can be operated by operating the knob, that is, moving the knob in the first direction or the second direction can drive the lifting assembly to move in the first direction or the second direction, and rotating the knob in the first direction or the second direction can drive the lifting assembly to rotate in the first direction or the second direction.

[0027] In one embodiment, the limiting member is fan-shaped.

[0028] The limiting member is set to be fan-shaped, and after the limiting member is rotated around a first direction or a second direction by a preset angle, the fan-shaped limiting member can be separated from the hard disk. BRIEF DESCRIPTION OF THE DRAWINGS

When in the fixed state, the pulling component is clamped on the cavity wall of the accommodating cavity 111, and the limiting component 200 is located on the separation path of the hard disk 700 relative to the motherboard 800 to prevent the hard disk 700 from moving away from the motherboard 800; the pulling component is separated from the cavity wall of the accommodating cavity 111, and the limiting component 200 deviates from the separation path, so that the hard disk 700 is switched from the fixed state to the unlocked state, and the hard disk 700 can be separated from the motherboard 800.

[0053] In the above-mentioned connection device between the hard disk and the motherboard, one end of the lifting component is located in the accommodating cavity 111 of the base 100, and the other end is arranged outside the accommodating cavity 111, and a limiting member 200 is arranged on the area outside the accommodating cavity 111 of the lifting component. When it is necessary to lock the hard disk 700 on the motherboard 800, that is, when the hard disk 700 is in a fixed state, the lifting component is clamped on the cavity wall of the accommodating cavity 111, and the limiting member 200 is located on the separation path of the hard disk 700 relative to the motherboard 800, thereby blocking the hard disk 700 from moving away from the motherboard 800. When it is necessary to release the hard disk 700, the lifting component is separated from the cavity wall of the accommodating cavity 111, and the limiting member 200 is deviated from the separation path, at which time the hard disk 700 can be switched from the fixed state to the unlocked state, and at this time the hard disk 700 can be separated from the motherboard 800. The connection device between the hard disk and the motherboard provided in the present application is crimped onto the separation path of the hard disk 700 by a blocking member, thereby blocking the separation of the hard disk 700 and the motherboard 800. The motherboard 800 and the hard disk 700 can be separated by simply separating the lifting assembly from the cavity wall of the accommodating cavity 111 and deviating the blocking member from the separation path.

[0054] Specifically, as shown in FIGS. 2 to 8 , the lifting assembly is configured to move along a first direction to extend into the accommodating cavity 111, and the lifting assembly is configured to move along a second direction and then rotate around the second direction to make the limiting member 200 deviate from the separation path, wherein the first direction and the second direction are opposite. When it is necessary to lock the hard disk 700 and the motherboard 800, the lifting assembly is first moved along the first direction to extend into the accommodating cavity 111, so that the lifting assembly is clamped on the cavity wall of the accommodating cavity 111, and then the limiting member 200 is pressed on the hard disk 700, thereby limiting the relative position between the hard disk 700 and the motherboard 800, and limiting the movement of the hard disk 700. When the hard disk 700 needs to be unlocked, the lifting assembly is first moved along the second direction to release the clamping relationship between the lifting assembly and the cavity wall of the accommodating cavity 111, and then the lifting assembly is rotated around the second direction, so that the limiting member 200 on the lifting assembly is away from the hard disk 700 to separate from the hard disk 700, so that the hard disk 700 is switched from the fixed state to the unlocked state, and it is convenient to remove the hard disk 700 from the main board 800. The connection device of the hard disk and the main board of the present application, when the hard disk 700 needs to be in the unlocked state, only needs to move the lifting assembly along the second direction and rotate around the second direction to release the fixation of the hard disk 700; when it is necessary to limit the positional relationship between the hard disk 700 and the main board 800, only needs to move the lifting assembly along the first direction, and then rotate the limiting member 200 around the first direction, so that the limiting member 200 is pressed on the hard disk 700, so that the relative position of the hard disk 700 and the main board 800 can be limited. The connection device of the hard disk and the main board of the present application is convenient for disassembly and assembly, and improves the disassembly and assembly efficiency.

[0055] It should be noted that the first direction and the second direction are opposite and both are parallel to the axial direction of the lifting component.

[0056] It should be noted that when the hard disk 700 and the mainboard 800 need to be locked, in some embodiments, the lifting assembly can be moved along the first direction first, and then the lifting assembly can be rotated around the first direction, so that the limiter 200 can be pressed against the hard disk 700. In other embodiments, the limiter 200 can be rotated first, and then the lifting assembly can be moved along the first direction, and the limiter 200 can be directly pressed against the hard disk 700.

[0057] Further, as shown in FIGS. 2 to 7 , the lifting assembly includes a lifting shaft 300 and a pressing shaft 400, the pressing shaft 400 is sleeved on the lifting shaft 300, and the end of the lifting shaft 300 extends out of the pressing shaft 400, the stopper 200 is connected to the pressing shaft 400, and when in a fixed state, the lifting shaft 300 is clamped on the cavity wall of the accommodating cavity 111, the lifting shaft 300 is configured to move along the second direction to separate the lifting shaft 300 from the cavity wall of the accommodating cavity 111, and the lifting shaft 300 and the pressing shaft 400 are configured to move synchronously around the second direction to deviate the stopper 200 from the separation path. The pressing shaft 400 is sleeved on the outside of the lifting shaft 300, and the stopper 200 is connected to the pressing shaft 400. The end of the lifting shaft 300 extends outside the pressing shaft 400, that is, the end of the lifting shaft 300 is exposed, so that when in a fixed state, the lifting shaft 300 is engaged with the cavity wall of the accommodating cavity 111. When it is necessary to separate the motherboard 800 and the hard disk 700, the lifting shaft 300 is first configured to move relative to the pressing shaft 400 along the second direction to release the engagement between the lifting shaft 300 and the cavity wall of the accommodating cavity 111, and then the lifting shaft 300 and the pressing shaft 400 are configured to rotate synchronously around the second direction, so that the limiting member 200 rotates around the second direction to separate from the hard disk 700.

When in a fixed state, the protrusion 310 is engaged with the groove 112, and when in an unlocked state, the protrusion 310 is arranged in the accommodating groove 410. The protrusion 310 is provided on the lifting shaft 300, and the groove 112 is provided on the cavity wall of the accommodating cavity 111. When the hard disk 700 is in a fixed state, the protrusion 310 is engaged with the groove 112, thereby defining the relative position of the lifting assembly and the base 100. Since the base 100 is mounted on the mainboard 800, the relative position of the lifting assembly and the mainboard 800 is also defined. When the protrusion 310 is engaged with the groove 112, the lifting assembly is rotated at this time, so that the limiting member 200 is pressed on the hard disk 700, thereby fixing the hard disk 700. In addition, a receiving groove 410 is provided on the end face of the pressing shaft 400 extending into the receiving cavity 111. When the lifting assembly is moved along the second direction, that is, when the lifting shaft 300 is moved along the second direction, the protrusion 310 on the lifting shaft 300 moves along the second direction, disengages from the groove 112, and then is inserted into the receiving groove 410. At this time, it means that the lifting assembly can be rotated around the second direction, which is convenient for subsequent unlocking action.

[0059] Specifically, as shown in Figures 2 to 8, a plurality of protrusions 310 are provided, and the plurality of protrusions 310 are arranged at intervals around the circumference of the lifting shaft 300, and a plurality of grooves 112 corresponding to the plurality of protrusions 310 are provided on the cavity wall of the accommodating cavity 111.

The limiting groove 113 is provided on the wall of the accommodating cavity 111. When the hard disk 700 is in a fixed state, that is, when the protrusion 310 and the groove 112 are correspondingly engaged, the exposed end of the lifting shaft 300 can also be engaged with the limiting groove 113, thereby improving the engagement stability between the lifting assembly and the wall of the accommodating cavity 111, and thus improving the fixing effect of the hard disk 700.

[0062] More specifically, as shown in FIG. 2 to FIG. 8 , the plurality of grooves 112 and the limiting grooves 113 are in communication.

[0063] Further, as shown in Figures 2 to 6, the connection device between the hard disk and the motherboard also includes an elastic member 500 disposed in the accommodating cavity 111, and the elastic member 500 is used to push the lifting shaft 300 to move along the first direction by its own elastic force. By arranging the elastic member 500 in the accommodating cavity 111, the lifting shaft 300 is pushed to move along the first direction by the elastic member 500, so that the protrusion 310 of the lifting shaft 300 and the groove 112 on the cavity wall of the accommodating cavity 111 are correspondingly engaged, locking the lifting shaft 300, and preventing the lifting shaft 300 from moving along the second direction.

[0064] Specifically, as shown in FIGS. 2 to 6 , the pressing shaft 400 is provided with an annular boss 420 located in the accommodating cavity 111, and the elastic member 500 is sleeved on the pressing shaft 400, and one end of the elastic member 500 abuts against the annular boss 420, and the other end abuts against the protrusion 310. The elastic member 500 is sleeved on the pressing shaft 400, and one end of the elastic member 500 abuts against the annular boss 420, and the other end abuts against the protrusion 310. The function of the elastic member 500 is to prevent the lifting shaft 300 from being in a free state. If unlocking is required, the elastic force of the elastic member 500 needs to be overcome to achieve the effect of preventing accidental touch. When it is necessary to unlock the hard disk 700, first move the lifting shaft 300 along the second direction. At this time, the elastic member 500 will be compressed, so that the protrusion 310 on the lifting shaft 300 will leave the groove 112 on the cavity wall of the accommodating cavity 111, and the protrusion 310 will enter the accommodating groove 410 at the end of the pressure plate. At this time, the first unlocking step has been completed, and then the lifting assembly can be rotated to make the limiting member 200 connected to the pressure shaft 400 rotate away from the hard disk 700 to complete the unlocking.

[0065] Further, as shown in FIGS. 2 to 8 , the base 100 includes a body 110 and a cover plate 120. The body 110 has a receiving cavity 111.

The receiving cavity 111 is provided on the body 110 to accommodate the end of the lifting assembly, and the cover plate 120 is provided to be connected to the body 110 to block the receiving cavity 111 to prevent external dust and water droplets from flowing into the receiving cavity 111.
