[0039] Existing electronic devices, especially big data analysis devices, usually set a fixed structure in the protective shell to fix the host in order to ensure the reliability of the host in the protective shell, so as to avoid the host and the protective shell from colliding with each other when the electronic device is shaken, resulting in damage to the components inside the host, so as to improve the reliability of the electronic device. However, after the fixed structure is used to limit the host, the relative friction between the host and the protective shell increases, making it difficult to take and place the host. Based on this, the present application provides a fixing device, which can be applied to electronic devices to fix the host and improve the reliability of the electronic device. Specifically, the top cover drives the driving assembly to move, so as to drive the clamping assembly to move relative to the host in the box, so as to clamp and release the host, so as to solve the problem of difficulty in taking and placing the host and affecting the reliability of the electronic device when the host is shaken.

[0040] In order to facilitate understanding of the structure of the fixing device and the electronic device, the fixing device and the electronic device will be further described below in conjunction with the embodiments and drawings. It should be noted that the following description is only for illustrative purposes and is not a specific limitation of the present application.

[0041] Please also read Figures 1 to 3The embodiment of the present application provides an electronic device 200, including a host 201 and a fixing device 100, wherein the fixing device 100 is used to fix the host 201. Specifically, the fixing device 100 includes a box body 10, a top cover 20, and a fixing module 30, wherein the box body 10 is provided with a first accommodating groove 11, wherein the first accommodating groove 11 has a first opening, wherein the first accommodating groove 11 is used to accommodate the host 201, wherein the top cover 20 can be movably connected to the box body 10 to cover or open the first opening, wherein the fixing module 30 includes a driving component 31 and a clamping component 32, wherein the driving component 31 is connected to the top cover 20, wherein the clamping component 32 is movably installed in the first accommodating groove 11, wherein the driving component 31 is used to drive the clamping component 32 to move in the first accommodating groove 11 under the action of the top cover 20, wherein the clamping component 32 is used to clamp the host 201 when the top cover 20 moves to cover the first opening, and wherein the clamping component 32 is also used to release the host 201 when the top cover 20 moves to open the first opening.

[0042] The fixing device 100 and the electronic device 200 provided in the embodiment of the present application are provided with a top cover 20 movably connected to the box body 10 to cover or open the first opening, so that the host 201 can be placed in the first receiving groove 11 through the first opening, or taken out from the box body 10 through the first opening, and the clamping assembly 32 of the fixing module 30 is movably installed in the first receiving groove 11, and the driving assembly 31 of the fixing module 30 is connected to the top cover 20. The driving assembly 31 is used to drive the clamping assembly 32 to move relative to the first receiving groove 11 under the action of the top cover 20, so that the clamping assembly 32 clamps or releases the host 201. Similarly, the top cover 20 moves relative to the case 10 to switch the clamping state of the clamping component 32 on the host 201. When the top cover 20 moves to cover the first opening, the driving component 31 drives the clamping component 32 to clamp the host 201, so that the host 201 can be clamped and fixed by the clamping component 32 to avoid relative collision between the host 201 and the case 10, thereby ensuring the reliability of the electronic device 200. When the host 201 needs to be taken or placed, the top cover 20 moves to open the first opening, so that the driving component 31 drives the clamping component 32 to release the host 201, so that the host 201 can be taken out of the case 10 or stored in the case 10.

[0043] This embodiment is described by taking the electronic device 200 as a big data analysis device as an example, and the host 201 is a big data server. The host 201 is located in the fixed device 100 when working, and the host 201 can be taken out of the fixed device 100 when the host 201 needs to be repaired and updated.

[0044] It can be understood that in some other embodiments, the electronic device 200 can also be a router, a switch or a computer.

[0045] In some embodiments, one end of the top cover 20 is rotatably connected to the box body 10 , so as to improve the convenience of the top cover 20 moving relative to the box body 10 , so as to facilitate the opening and closing of the first opening, and improve the integrity of the fixing device 100 .

[0046] It is understandable that in other embodiments, the top cover 20 may also be snap-connected with the box body 10 to facilitate the disassembly of the top cover 20 and the box body 10 .

[0047] Optionally, the top cover 20 is provided with a handle 21, which is located on a side of the top cover 20 away from the rotational connection between the top cover 20 and the box body 10. This makes it easier for an operator to control the rotation of the top cover 20 relative to the box body 10, so as to open and close the first opening, thereby facilitating the taking and placing of the host 201.

[0048] In some embodiments, the top cover 20 is provided with a protective pad 22, and the protective pad 22 is provided with a second accommodating groove 220 with an opening toward the box body 10, and the second accommodating groove 220 is connected to the first accommodating groove 11. When the top cover 20 covers the first opening, the host 201 at least partially extends into the second accommodating groove 220 and abuts against the inner wall of the second accommodating groove 220. In this way, the host 201 can be limited to improve the reliability of the electronic device 200, and the protective pad 22 can be used for shock absorption to reduce the external force impact on the host 201.

[0049] It is understandable that in other embodiments, the protection pad 22 may also be a sheet-like structure, and abuts against the host 201 when the top cover 20 covers the first opening.

[0050] In some embodiments, the box body 10 is provided with a first fixed groove 12 connected to the first accommodating groove 11, and the clamping assembly 32 includes at least two groups of clamping parts arranged opposite to each other, and the at least two groups of clamping parts are respectively arranged on the outer periphery of the main unit 201, and each clamping part includes a first piston plate 321, a connecting rod 322 and a protective plate 323. The first piston plate 321 is connected to one end of the connecting rod 322, the protective plate 323 is connected to the other end of the connecting rod 322 and is located in the first accommodating groove 11, and the side of the protective plate 323 away from the connecting rod 322 can be movably connected to the main unit 201, and the first piston plate 321 can be movably installed in the first fixed groove 12, and the first piston plate 321 is used to move in a direction close to or away from the main unit 201 under the drive of the driving assembly 31.

[0051] In this way, the clamping assembly 32 clamps and releases the host 201 through piston-like motion, which can improve the flexibility of the clamping assembly 32 relative to the host 201 and facilitate the taking and placing of the host 201.

[0052] Optionally, as can be seen from the above, when the top cover 20 covers the first opening, the host 201 stored in the first receiving groove 11 at least partially extends into the second receiving groove 220, and the protective pad 22 abuts against the host 201, that is, the top cover 20 limits the top of the host 201 through the protective pad 22, based on which, at least two groups of clamping parts are respectively arranged on the left and right sides or the front and back sides of the host 201, or at least two groups of clamping parts are simultaneously arranged on the left and right sides and the front and back sides of the host 201. In this way, when the top cover 20 covers the first opening, the bottom of the host 201 is supported by the bottom wall of the first receiving groove 11, the top of the host 201 is limited by the protective pad 22, and the middle of the host 201 is clamped and fixed by at least two groups of clamping parts, so that the host 201 can be fixed in all directions, so as to improve the stability of the host 201 in the box 10 and improve the reliability of the electronic device 200.

[0053] It is understandable that in other embodiments, the clamping assembly 32 may also be clamped on the upper and lower sides of the host 201 .

[0054] Optionally, each group of clamping parts may have multiple connecting rods 322, which are arranged at intervals, so as to make the supporting force of the protection plate 323 on the host 201 more uniform, thereby improving the stability of the protection plate 323 supporting the host 201, and further improving the reliability of the electronic device 200.

[0055] Exemplarily, each group of clamping parts has two connecting rods 322, which are respectively disposed at both ends of the protection plate 323. This ensures the stability of the protection plate 323 supporting the host 201, reduces the number of connecting rods 322, and reduces the weight of the fixing device 100.

[0056] Optionally, a third limiter 121 is provided in the first fixed groove 12. The third limiter 121 is located on a side of the first piston plate 321 close to the protective plate 323. The third limiter 121 is used to limit the movement stroke of the first piston plate 321 to prevent the first piston plate 321 from slipping out of the first fixed groove 12, thereby limiting the movement stroke of the protective plate 323 and controlling the clamping force of the protective plate 323 on the main machine 201.

[0057] In some embodiments, the housing 10 is provided with an air cavity 13 and a first through hole and a second through hole communicating with the air cavity 13. The air cavity 13 is spaced apart from the first fixed groove 12 and the first accommodating groove 11. The air cavity 13 is connected to the first fixed groove 12 through the first through hole. The driving assembly 31 includes a second piston plate 311, an extrusion plate 312 and an extrusion rod 313. The extrusion rod 313 is movably inserted into the second through hole. The second piston plate 311 is connected to one end of the extrusion rod 313 and is located in the air cavity 13. The second piston plate 311 is movably installed between the first through hole and the second through hole. The extrusion plate 312 is connected to the other end of the extrusion rod 313 and is located outside the air cavity 13. The side of the extrusion plate 312 away from the extrusion rod 313 is movably connected to the top cover 20. The extrusion plate 312 is used to push the second piston plate 311 to move under the action of the top cover 20, so as to drive the first piston plate 321 to move in a direction close to or away from the host 201.

[0058] In this way, the top cover 20 drives the squeezing plate 312 to move, thereby driving the second piston plate 311 to move, so as to provide the clamping part with power to move relative to the host 201, thereby saving the driving energy consumption of the fixing module 30. At the same time, the driving assembly 31 is arranged in the air cavity 13 of the box body 10, which can also help improve the integrity of the electronic device 200. The squeezing rod 313 extends out of the air cavity 13 through the second through hole and is connected to the squeezing plate 312, which helps to ensure the sealing of the air cavity 13, so as to ensure that the substance (such as gas or liquid, etc.) used to drive the first piston plate 321 to move will not leak.

[0059] It is understandable that in other embodiments, the drive assembly 31 may also include a shell having an air cavity 13 , and the shell is fixed to the housing 10 , so that the drive assembly 31 is designed independently of the housing 10 , which is beneficial to the maintenance and updating of the drive assembly 31 .

[0060] Optionally, the driving assembly 31 drives the clamping assembly 32 to move by compressed gas, that is, by controlling the second piston plate 311 to move in the air cavity 13 in the direction away from the top cover 20, so as to drive the gas in the air cavity 13 to enter the first fixed groove 12 through the first through hole, and the first piston plate 321 is pushed by the gas to move in the first fixed groove 12, thereby driving the protective plate 323 to move toward the main unit 201. When the second piston plate 311 moves toward the direction close to the top cover 20, the gas in the first fixed groove 12 can enter the air cavity 13 through the first through hole to cancel the squeezing force of the protective plate 323 on the main unit 201, thereby facilitating the movement of the main unit 201 relative to the box body 10 to remove the main unit 201.

[0061] It can be understood that in other embodiments, the driving component 31 can also drive the clamping component 32 to move through pressure fluid or a reset structure.

[0062] Optionally, the extrusion plate 312 is in contact connection with the top cover 20, and the driving assembly 31 further comprises a first reset structure 314, which is connected to the second piston plate 311, and is used to drive the second piston plate 311 to reset when the top cover 20 moves in a direction away from the extrusion plate 312. This can not only reduce the traction restriction when the top cover 20 rotates relative to the box body 10, which is beneficial to the opening and closing of the top cover 20, but also ensure that when the top cover 20 moves to open the first opening, the second piston plate 311 can be reset in a direction away from the box body 10, so as to drive the first piston plate 321 to drive the protection plate 323 to move in a direction away from the host 201, so that the clamping assembly 32 releases the host 201, so that the host 201 can be taken out of the box body 10.

[0063] It is understandable that in other embodiments, the squeezing plate 312 may also be fixedly connected to the top cover 20 , and the top cover 20 may drive the squeezing plate 312 to move toward or away from the box body 10 to control the clamping part to clamp or release the host 201 .

[0064] Optionally, the first reset structure 314 may be an elastic member (such as a compression spring or a tension spring, etc.), one end of the first reset structure 314 is connected to the second piston plate 311, and the other end of the first reset structure 314 is connected to the inner wall of the air cavity 13, so that it can generate an elastic restoring force when the top cover 20 drives the extrusion plate 312 to move toward the direction of the box body 10, so that when the top cover 20 is rotated relative to the box body 10 to open the first opening, the second piston plate 311 is driven to move in the direction away from the box body 10 by the elastic restoring force of the first reset structure 314, so as to drive the clamping assembly 32 to release the main unit 201.

[0065] It can be understood that in other embodiments, the first reset structure 314 can also be two mutually cooperating wedge-shaped sliders, or a cam mechanism, etc.

[0066] Optionally, the first reset structure 314 is located between the second piston plate 311 and the extrusion plate 312 , thereby avoiding occupying the structural space for driving the first piston plate 321 to move, so as to increase the movement distance of the first piston plate 321 .

[0067] It can be understood that in some other embodiments, the first reset structure 314 may also be located on a side of the second piston plate 311 away from the extrusion plate 312 .

[0068] In some embodiments, the driving assembly 31 further includes a first stopper 315, which is installed in the air cavity 13 and located between the second piston plate 311 and the first through hole. Thus, the movement stroke of the second piston plate 311 can be limited, which is conducive to ensuring the reliability of the driving assembly 31, and preventing the second piston plate 311 from moving to block the first through hole, affecting the gas flow between the air cavity 13 and the first fixed groove 12, or the second piston plate 311 from moving over the first through hole, causing gas leakage in the first fixed groove 12.

[0069] Optionally, the first limiting member 315 may be a limiting block, a limiting column or a limiting plate, etc., which may be specifically configured according to actual needs and is not limited here.

[0070] Optionally, the box body 10 is provided with a second fixing groove 14 , the opening of the second fixing groove 14 faces the top cover 20 , the extrusion plate 312 is movably mounted in the second fixing groove 14 , and the extrusion rod 313 is passed through the bottom of the second fixing groove 14 to be connected to the extrusion plate 312 .

[0071] By setting the second fixed groove 14, the movement stroke of the extrusion plate 312 can be limited, so as to control the movement stroke of the second piston plate 311 together with the first limiter 315, thereby improving the structural reliability of the drive assembly 31 and avoiding the second piston plate 311 damaging the first limiter 315 due to excessive movement distance of the extrusion plate 312, so that the second piston plate 311 moves to block or cross the first through hole.

[0072] In some embodiments, considering that the host 201 will generate heat when working in the box 10, the overheated working environment will affect the operation of the components inside the host 201, resulting in a decrease in the working efficiency of the host 201 or an inability to move. Based on this, the fixing device 100 also includes a heat dissipation module 40, and the heat dissipation module 40 includes a heat dissipation shell 41, a fan 42 and a ventilation net 43. The heat dissipation shell 41 is provided with a heat dissipation space 410 inside, and the heat dissipation space 410 is connected to the first accommodating groove 11. The ventilation net 43 and the fan 42 are respectively installed on the heat dissipation shell 41, and the ventilation net 43 is connected to the heat dissipation space 410 and the external environment. The fan 42 is used to drive the air circulation in the heat dissipation space 410.

[0073] In this way, the low-temperature gas in the external environment is driven by the fan 42 to enter the heat dissipation space 410 and the first receiving groove 11 in sequence through the ventilation net 43 to cool down and dissipate the heat of the host 201 placed in the first receiving groove 11.

[0074] Optionally, the heat dissipation module 40 is disposed at the bottom of the housing 10 and below the first receiving groove 11 , thereby improving the heat dissipation efficiency of the host 201 while ensuring the structural stability of the host 201 relative to the housing 10 .

[0075] Optionally, the heat dissipation module 40 further includes a cleaning brush 44 , which is connected to the fan 42 and contacts a side of the ventilation net 43 away from the heat dissipation housing 41 , and is configured to rotate relative to the ventilation net 43 driven by the fan 42 .

[0076] In this way, when the fan 42 is rotating, the cleaning brush 44 is driven by the fan 42 to rotate relative to the ventilation net 43 to sweep away the dust on the side of the ventilation net 43 away from the heat dissipation shell 41, thereby achieving the effect of cleaning the ventilation net 43, reducing the accumulation of dust on the ventilation net 43, and avoiding the blockage of the ventilation net 43, so that air can pass through the ventilation net 43, improve the air circulation efficiency in the heat dissipation space 410, and further improve the heat dissipation efficiency of the host 201, so as to ensure the working temperature of the host 201 and avoid the situation that the data processing efficiency is affected by the overheating of the host 201.

[0077] Optionally, the cleaning brush 44 can be any one of a brush, a sponge or a rag, etc., and can be set according to actual needs and is not limited here.

[0078] Optionally, the fan 42 includes a fan body, a rotating shaft and a driving motor. The driving motor and the fan body are installed in the heat dissipation space 410. The output shaft of the driving motor is connected to the rotating shaft. The rotating shaft is installed in the center of the fan body. The rotating shaft passes through the ventilation net 43 and extends out of the heat dissipation housing 41 to be connected to the cleaning brush 44. Therefore, when the driving motor drives the fan body to rotate, the rotating shaft synchronously drives the cleaning brush 44 to rotate relative to the ventilation net 43, so that the fan 42 can clean the ventilation net 43 while passing low-temperature gas into the heat dissipation space 410, thereby improving the ventilation efficiency and the heat dissipation efficiency of the host 201. At the same time, the fan body and the driving motor are installed in the heat dissipation space 410, which can also help reduce the dust accumulation on the fan body and the driving motor, so as to improve the working efficiency and operation reliability of the fan 42.

[0079] It is understandable that in other embodiments, the fan 42 may also be installed outside the heat dissipation space 410 .

[0080] In some embodiments, the heat dissipation module 40 further includes an air guide plate 45, the box body 10 is provided with an air cavity 15, the air cavity 15 is connected to the heat dissipation space 410 and the first receiving groove 11, and the air guide plate 45 is arranged in the air cavity 15, and the air guide plate 45 is used to guide the airflow to flow toward the first receiving groove 11. This is conducive to improving the heat dissipation efficiency, so as to improve the working efficiency of the host 201.

[0081] Optionally, the air guide plate 45 is arranged to be inclined toward the first receiving groove 11 in a direction from the edge to the center of the box body 10 to ensure that the air guide plate 45 can guide the airflow entering the air cavity 13 to flow toward the first receiving groove 11 .

[0082] Optionally, considering that when the top cover 20 is rotated relative to the box body 10 to open the first opening, dust or impurities in the air may enter the first receiving groove 11, and the dust and impurities may affect the operation of the fan 42. Based on this, the box body 10 is also provided with a second air flow channel 16, and the second air flow channel 16 is connected to the wind cavity 15 and the heat dissipation space 410, so that on the one hand, the area of ​​the wind cavity 15 can be reduced, so as to ensure the supporting reliability of the box body 10 for the host 201 and improve the reliability of the electronic device 200. On the other hand, the risk of dust in the first receiving groove 11 flowing to the fan 42 via the air cavity 13 can be reduced, so as to improve the operating reliability of the fan 42.

[0083] Optionally, there may be a plurality of second airflow channels 16 , and the plurality of second airflow channels 16 are arranged at intervals, thereby ensuring the flow efficiency of the gas.

[0084] Please combine Figure 1 , Figure 2 as well as Figure 4 In some embodiments, the heat dissipation module 40 also includes a dust shield component 46. The box body 10 is provided with a first air flow channel 17. The first air flow channel 17 is connected to the air cavity 15 and the first receiving groove 11. The first air flow channel 17 is used to supply the air flow in the air cavity 15 to enter the first receiving groove 11. The dust shield component 46 can be movably installed on the first air flow channel 17 to control the opening and closing of the first air flow channel 17.

[0085] In this way, when the fan 42 drives the low-temperature gas in the external environment to sequentially pass through the ventilation net 43, the heat dissipation space 410, and the air cavity 15 to reach the first airflow channel 17, the airflow can push the dust shielding assembly 46 to move to open the first airflow channel 17 to enter the first receiving groove 11 to cool and dissipate heat to the host 201. At this time, due to the effect of the airflow, the dust in the first receiving groove 11 will not flow back into the air cavity 15. After the heat dissipation of the host 201 is completed, the fan 42 is turned off, and the dust shielding assembly 46 moves to close the first airflow channel 17 to prevent the dust in the first receiving groove 11 from entering the air cavity 15, thereby ensuring that the fan 42 will not be affected by the dust in the first receiving groove 11.

[0086] Optionally, the dust shield assembly 46 includes a dust shield plate 461 and a second reset structure 462, the dust shield plate 461 is rotatably connected to the box body 10 to open or close the first airflow channel 17, and the second reset structure 462 is connected to the dust shield plate 461, and the second reset structure 462 is used to drive the dust shield plate 461 to rotate to close the first airflow channel 17. This can help control the dust shield plate 461 to open or close the first airflow channel 17, and improve the flexibility and reliability of the dust shield assembly 46.

[0087] Optionally, the second reset structure 462 is an elastic member, one end of the dust baffle plate 461 can be rotatably connected to the inner wall of the first airflow channel 17 and extend along the width direction of the first airflow channel 17, the other end of the dust baffle plate 461 is connected to the second reset structure 462, and the end of the second reset structure 462 away from the dust baffle plate 461 is connected to the inner wall of the first airflow channel 17.

[0088] In this way, on the one hand, the sealing of the dust baffle 461 when it is rotated to close the first air flow channel 17 can be ensured, and on the other hand, the path size for the airflow to pass through can be ensured when the dust baffle 461 is rotated to open the first air flow channel 17, so as to increase the flow rate of the airflow in the first air flow channel 17, thereby improving the heat dissipation effect of the main unit 201.

[0089] Optionally, the end of the second reset structure 462 away from the dust baffle 461 is spaced apart from the dust baffle 461 and connected to the inner wall on the same side of the first air flow channel 17, thereby facilitating the rotation of the dust baffle 461 relative to the first air flow channel 17, so as to facilitate the air flow to enter the first accommodating groove 11.

[0090] It can be understood that in other embodiments, the end of the second restoring structure 462 away from the dust shielding plate 461 may also be connected to the inner wall of the first receiving groove 11 or the inner wall of the air cavity 13 .

[0091] Optionally, the second reset structure 462 may be any one of a tension spring, an elastic rope or a leaf spring, etc., and may be specifically configured according to actual needs and is not limited here.

[0092] It can be understood that in other embodiments, the dust shield assembly 46 can also be connected to the middle part of the dust shield plate 461 (here it does not refer to the center, but refers to the area except the end) through one end of the support column, and the other end of the support column is connected to the inner wall of the first accommodating groove 11 or the inner wall of the air cavity 13, and the second reset structure 462 can also be a torsion spring arranged on the dust shield plate 461.

[0093] In some embodiments, the dust shield assembly 46 further includes a stopper 463, which is disposed on the inner wall of the first airflow channel 17 and is used to limit the rotation angle of the dust shield plate 461 relative to the first airflow channel 17. Thus, the second reset structure 462 can drive the dust shield plate 461 to rotate to close the first airflow channel 17 and stop the movement, so as to ensure the sealing performance of the dust shield plate 461 to the first airflow channel 17.

[0094] Optionally, the stopper 463 is arranged on the side of the dust baffle 461 close to the air cavity 13, so as to ensure that the stopper 463 is limited when the dust baffle 461 closes the first air flow channel 17, and to prevent the stopper 463 from hindering the movement of the dust baffle 461 when the dust baffle 461 rotates in the direction of opening the first air flow channel 17, so as to improve the reliability of the rotation of the dust baffle 461 relative to the first air flow channel 17.

[0095] In some embodiments, there may be multiple first airflow channels 17 and multiple dust shielding components 46, and multiple first airflow channels 17 correspond to multiple dust shielding components 46 one by one. Multiple first airflow channels 17 are arranged at intervals and located at the bottom of the first accommodating groove 11, thereby ensuring the stability of the host 201 in the box 10 and improving the heat dissipation efficiency of the heat dissipation module 40 on the host 201.
