A plug connector is provided on one side of the chassis, and a door panel is pivotally connected to the other side. Multiple electronic modules are installed within the chassis, and a clamping device within the chassis secures the modules. Before opening or closing the door panel, the clamping device must be operated separately to compress and secure the electronic modules, which is quite cumbersome.

[0004] The chassis in the related art cannot realize the cooperation between the pressing device and the door panel, and after closing the door panel, the pressing device can automatically press to fix the electronic module. Summary of the Invention

[0005] In view of this, the present application provides a chassis and an electronic device to solve or improve the problem that the pressing device cannot automatically press the electronic module after the door panel is closed.

[0006] In a first aspect, the present application provides a chassis, comprising: The box body has a door panel rotatably arranged on an opening on one side thereof; A plurality of cavities are arranged at intervals along a first direction on the inner side plate of the box body, each of the cavities is provided with a first through hole and a second through hole, the axial direction of the first through hole is parallel to the first direction, the axial direction of the second through hole intersects with the first direction, and a pressure transmission medium is provided in the cavity; An extrusion frame is provided with a plurality of filling blocks, wherein the plurality of filling blocks are slidably and sealingly connected to the plurality of first through holes, and one end of the extrusion frame is capable of slidably abutting against the door panel; A plurality of extrusion blocks are slidably and sealingly connected to the plurality of second through holes in a one-to-one correspondence, and the extrusion blocks are suitable for pressing the electronic module tightly into the box.

[0007] In this embodiment, the electronic module is placed into the box from the opening, and the door panel is rotated.

The filling block penetrates into the cavity, compresses the volume of the pressure transmission medium in the cavity, and then increases the pressure of the pressure transmission medium, and the increased pressure acts on the extrusion block. The extrusion block extends out of the cavity along the axial direction of the second through hole and is suitable for pressing on the electronic module. The electronic module is fixed at multiple points to solve or improve the problem that the electronic module cannot be automatically pressed after the door panel is closed.

[0014] The usual cabinet is a standard 19-inch (equipment installation rail width is 19 inches) rack-mounted structure, which is suitable for most servers, switches, routers and other communication equipment.

[0015] In the prior art, a quick-plug server consists of a rack-mounted chassis and electronic modules installed within it. A plug connector is provided on one side of the chassis, and a door panel is pivotally connected to the other side. Multiple electronic modules are installed within the chassis, and a clamping device within the chassis secures the modules. Before opening or closing the door panel, the clamping device must be operated separately to compress and secure the electronic modules, which is quite cumbersome.

[0016] The chassis in the related art cannot realize the cooperation between the clamping device and the door panel, so that the clamping device can automatically clamp and fix the electronic module after the door panel is closed. Therefore, the present application provides a chassis and electronic equipment to solve or improve the problem of not being able to effectively fix multiple electronic modules at multiple points.

[0017] The following combination Figures 1 to 14 , describing the embodiments of the present application.

[0018] According to an embodiment of the present application, on the one hand, a chassis is provided, including: a chassis body 1, a plurality of cavities 3, an extrusion frame 5 and a plurality of extrusion blocks 7.

[0019] Specifically, such as Figure 1 、 Figure 2 、 Figure 5 、 Figure 7 and Figure 8As shown, the box body 1 has a door panel 2 rotatably arranged on an opening on one side thereof; a plurality of cavities 3 are arranged at intervals on the inner panel of the box body 1 along the first direction X, and each cavity 3 is provided with a first through hole 301 and a second through hole, the axial direction of the first through hole 301 is parallel to the first direction X, and the axial direction of the second through hole intersects with the first direction X, and a pressure transmission medium is arranged in the cavity 3; the extrusion frame 5 is provided with a plurality of filling blocks 6, and the plurality of filling blocks 6 are slidingly and sealingly connected to the plurality of first through holes 301, and one end of the extrusion frame 5 can be slidably abutted against the door panel 2; a plurality of extrusion blocks 7 are slidingly and sealingly connected to the plurality of second through holes in a one-to-one correspondence, and the extrusion blocks 7 are suitable for pressing the electronic module 10 into the box body 1.

[0020] In this embodiment, if Figure 1 、 Figure 2 、 Figure 5 、 Figure 7 and Figure 8 As shown, an opening is provided on one side of the box body 1. The electronic module 10 is placed into the box body 1 through the opening. The door panel 2 is rotated. The door panel 2 can abut against the extrusion frame 5 before the opening is completely closed. The extrusion frame 5 is slidably connected to the box body 1 along the first direction X. As the door panel 2 is completely closed, the door panel 2 slides and abuts against the extrusion frame 5. The door panel 2 drives the extrusion frame 5 to move along the first direction X, that is, along the depth direction of the box body 1. At the same time, the filling block 6 on the extrusion frame 5 penetrates into the corresponding first through hole 301. Before the filling block 6 completely enters the cavity 3 from the first through hole 301, the pressure of the pressure transmission medium in the cavity 3 is the initial pressure. The filling block 6 penetrates into the cavity 3, compresses the volume of the pressure transmission medium in the cavity 3, and then increases the pressure of the pressure transmission medium, and the increased pressure acts on the extrusion block 7. The extrusion block 7 extends out of the cavity 3 along the axial direction of the second through hole and is suitable for pressing on the electronic module 10 to fix the electronic module 10 at multiple points to solve or improve the problem that the electronic module 10 cannot be automatically pressed after the door panel 2 is closed.

[0021] Specifically, the axial direction of the second through hole is perpendicular to the first direction X.

[0022] In one embodiment, along the first direction X, first through holes 301 are opened on the two opposite side walls of each cavity 3, and an elastic tube 4 is provided in each cavity 3. The two ends of the elastic tube 4 are sealedly connected to the corresponding two first through holes 301. The extrusion frame 5 slides through the multiple elastic tubes 4 in sequence along the first direction X, and the multiple filling blocks 6 can be inserted into the corresponding elastic tubes 4.

[0023] like Figure 1 、 Figure 5 and Figure 8As shown, multiple cavities 3 are arranged at intervals along the first direction X, and the extrusion frame 5 slides sequentially along the first direction X to penetrate multiple elastic tubes 4. The extrusion frame 5 is provided with multiple filling blocks 6 suitable for penetrating into the elastic tube 4. Multiple filling blocks 6 can simultaneously penetrate into their corresponding elastic tubes 4. An accommodating space is formed between the outer wall of the elastic tube 4 and the inner wall of the cavity 3. A pressure transmission medium is provided in the accommodating space. The pressure transmission medium fills the accommodating space. Before the filling block 6 enters the elastic tube 4, the elastic tube 4 is compressed under the pressure of the pressure transmission medium. As the door panel 2 is closed, multiple The filling block 6 is simultaneously inserted into the corresponding elastic tube 4, and the volume of the elastic tube 4 increases, thereby squeezing the pressure transmission medium in the cavity 3 to increase the pressure of the pressure transmission medium on the extrusion block 7. Under the pressure of the pressure transmission medium, the extrusion block 7 extends out of the cavity 3 along the axial direction of the second through hole. The extrusion block 7 is pressed tightly on the electronic module 10, wherein the axial direction of the second through hole is parallel to the width direction of the box body 1. Multiple extrusion blocks 7 fix the electronic module 10 at multiple points, and the number of cavities 3 is large and the volume is small, which is suitable for the current dense installation of electronic modules 10.

[0024] In some embodiments, as Figure 8 As shown, an end of the filling block 6 close to the first through hole 301 along the first direction X is provided with an inclined surface to facilitate the filling block 6 to penetrate into the elastic tube 4 .

[0025] In some embodiments, as Figure 11 As shown, multiple cavities 3 are arranged in the box body 1 and are located on both sides of its width. The multiple cavities 3 on the left are connected to an extrusion rack 5, and the multiple cavities 3 on the right are connected to an extrusion rack 5. The second through holes opened on the left cavity 3 and the right cavity 3 are arranged relative to each other. Rotating the door panel 2 can simultaneously drive the extrusion racks 5 on both sides to move along the first direction X.

[0026] In some embodiments, as Figure 2 and Figure 8 As shown, it also includes a guide member 504, which is fixed to the inner wall of the box body 1. The guide member 504 is provided with a first guide hole, the axial direction of the first guide hole is parallel to the first direction X, and the extrusion frame 5 is slidably connected to the first guide hole.

[0027] In some embodiments, as Figure 8 As shown, the extrusion frame 5 includes a connecting rod 502 and a plurality of connecting plates 501. Two adjacent filling blocks 6 are connected by the connecting plate 501. The connecting plate 501 can pass through the elastic tube 4. The surface of the connecting plate 501 is provided with a sliding hole 5011. The extension direction of the sliding hole 5011 is parallel to the first direction X. The inner wall of the box body 1 is provided with a connecting block 503. The connecting block 503 is slidably connected to the sliding hole 5011 for supporting the connecting plate 501 and guiding the connecting plate 501. The connecting rod 502 is slidably connected to the first guide hole.

[0028] Specifically, such as Figure 7 and Figure 8 As shown, each cavity 3 is provided with two first through holes 301 on one side along the first direction X, and the two first through holes 301 are arranged at intervals along the height direction of the cavity 3, that is, arranged at intervals along the second direction Z, wherein the height direction of the cavity 3 is parallel to the height direction of the box body 1, and a plurality of connecting plates 501 form two rows, each row corresponding to a group of first through holes 301 passing through along the first direction X, and the connecting block 503 is a U-shaped frame, and the two side plates of the U-shaped frame are respectively slidably connected to the sliding holes 5011 of the upper and lower rows of connecting plates 501, and the connecting rod 502 is bent to form a U-shaped rod, and the U-shaped rod is connected to the two filling blocks 6 at the head end of the extrusion frame 5.

[0029] In some embodiments, the pressure transmission medium is water or an incompressible liquid, or the pressure transmission medium may be gas, or the pressure transmission medium may be a flowing substance, such as sand or particles.

[0030] In some embodiments, as Figure 1 As shown, a handle 21 is provided on the door panel 2 .

[0031] In some embodiments, as Figure 5 As shown, it also includes a seal 14 with a cavity, the seal 14 is provided with a first connecting hole and a second connecting hole, the seal 14 is arranged in the cavity 3, and the first connecting hole corresponds to the second through hole, the edge of the first connecting hole is sealedly connected to the edge of the second through hole, and the edge of the second connecting hole is sealedly connected to the peripheral side of the extrusion block 7.

[0032] In this embodiment, if Figure 5 As shown, the first connecting hole of the seal 14 is sealed to the edge of the second through hole, and the second connecting hole is sealed to the peripheral side of the extrusion block 7, which can prevent the pressure transmission medium in the cavity 3 from leaking from the second through hole, thereby improving the sealing effect of the second through hole.

[0033] In one implementation, Figure 5 and Figure 6 As shown, it also includes at least one thermal expansion block 11. A mounting groove is opened on the inner wall of the extrusion block 7 corresponding to the second through hole. The thermal expansion block 11 is installed in the mounting groove. When the thermal expansion block 11 reaches the threshold temperature, it can extend out of the notch of the mounting groove and abut against the outer wall of the cavity 3.

[0034] In this embodiment, after the door panel 2 is closed, the extrusion block 7 extends out of the second through hole and squeezes the electronic module 10 under the pressure of the pressure transmission medium, and the thermal expansion block 11 extends out of the second through hole along with the extrusion block 7. The thermal expansion block 11 expands along the first direction X. After the electronic module 10 has worked for a period of time, the temperature rises. After the temperature of the thermal expansion block 11 reaches the threshold temperature, it expands, extends out of the installation groove, and abuts against the outer wall of the cavity 3. When the door panel 2 is opened, under the pressure of the pressure transmission medium, or the staff pulls the extrusion frame 5, the filling block 6 is pulled out of the elastic tube 4, the pressure in the cavity 3 is reduced, and the extrusion block 7 has a tendency to retract into the cavity 3. However, the thermal expansion block 11 abuts against the outer wall of the cavity 3, so that the extrusion block 7 continues to squeeze the electronic module 10, preventing the staff from removing the electronic module 10 before the temperature of the electronic module 10 drops below the threshold temperature and scalding the staff. After opening the door panel 2, when the temperature of the electronic module 10 drops below the threshold temperature, the thermal expansion block 11 retracts into the installation groove, and the extrusion block 7 can retract into the cavity 3, away from the electronic module 10. At this time, the staff can take the electronic module 10 out of the box 1 and replace or repair it.

[0035] In some embodiments, as Figure 5 As shown, the extrusion block 7 is provided with two mounting grooves, which are arranged on two opposite sides of the extrusion block 7 , and the two thermal expansion blocks 11 are respectively arranged in the two mounting grooves.

[0036] Specifically, the volume of the thermal expansion block 11 changes normally at a temperature between 40° C. and 70° C.

[0037] Specifically, the threshold temperature is 40°C.

[0038] Specifically, the thermal expansion block 11 is a thermal expansion polymer, which may be a low-crosslinking rubber (such as silicone rubber, EPDM); or a thermoplastic (such as LDPE, HDPE).

[0039] Specifically, the thermal expansion block 11 may be made of a shape memory alloy according to actual conditions. Shape memory alloy (such as Nitinol) is the first choice, and its expansion rate can reach 8%.

[0040] In one implementation, Figure 5 and Figure 6 As shown, it also includes at least one hydraulic rod assembly 12, which is arranged in the cavity 3, and the piston rod of the hydraulic rod assembly 12 is connected to the extrusion block 7. The pressure transmission medium is suitable for entering and exiting the liquid hole of the hydraulic rod assembly 12 to drive the piston rod of the hydraulic rod assembly 12 to extend and retract.

[0041] In this embodiment, if Figure 5 and Figure 6As shown, the pressure transmission medium enters and exits the liquid hole of the hydraulic rod assembly 12 to control the extension and retraction of the piston rod. When the filling block 6 enters the elastic tube 4, the volume of the elastic tube 4 increases, compressing the pressure transmission medium in the cavity 3. The pressure transmission medium enters the hydraulic rod assembly 12 from the liquid hole, pushing its piston rod to extend, and the piston rod pushes the extrusion block 7 to extend out of the cavity 3.

[0042] In some embodiments, the hydraulic rod assembly 12 includes a first cylinder body, a first piston and a first piston rod. The first piston is sealingly and slidingly connected in the first cylinder body. One end of the first piston rod is connected to the first piston, and the other end is connected to the extrusion block 7. A rodless cavity is formed between the first piston and the first cylinder body. A liquid hole is opened on the first cylinder body, and the liquid hole is connected to the rodless cavity.

[0043] Specifically, the hydraulic rod assembly 12 can be a hydraulic telescopic rod in the related art.

[0044] In one implementation, Figure 6 As shown, it also includes at least one first elastic component 13, which is arranged in the cavity 3. One end of the first elastic component 13 is connected to the inner wall of the cavity 3, and the other end is connected to the extrusion block 7. Under the elastic force of the first elastic component 13, the extrusion block 7 has a tendency to retract into the cavity 3.

[0045] In this embodiment, if Figure 5 and Figure 6 As shown, when the door panel 2 is opened, the door panel 2 loses pressure on the extrusion frame 5, and under the pressure of the pressure transmission medium, the filling block 6 is squeezed out of the elastic tube 4, or the staff pulls the extrusion frame 5 to pull the filling block 6 out of the elastic tube 4, and the pressure transmission medium loses pressure on the hydraulic rod assembly 12. At the same time, the first elastic assembly 13 applies a pulling force to the extrusion block 7 to pull the extrusion block 7 back into the cavity 3, which can ensure that after the door panel 2 is opened, the extrusion block 7 loses the extrusion force on the electronic module 10, making it convenient for the staff to disassemble the electronic module 10.

[0046] Specifically, the first elastic component 13 may be a first spring or a spring-type telescopic rod in related technologies.

[0047] In some embodiments, any number of first elastic components 13 can be provided according to actual needs.

[0048] In one implementation, Figure 5 As shown, the sealing member 14 is a flexible tube, one end of which is sealedly connected to the edge of the second through hole, and the other end of which is sealedly connected to the peripheral side of the extrusion block 7 via a sealing ring 22 .

[0049] In this embodiment, the length of the flexible tube can be changed with the movement of the extrusion block 7 without affecting the movement of the extrusion block 7 .

[0050] In some embodiments, the flexible tube is a bellows, the axial direction of the bellows is the same as the direction of expansion and contraction of the extrusion block 7, and the material of the flexible tube is rubber.

[0051] In one implementation, Figure 1 、 Figure 9 and Figure 11 As shown, it also includes multiple installation components 8, and the multiple installation components 8 are arranged in the box body 1 at intervals along the second direction Z. A plurality of receiving grooves 15 are formed between the multiple installation components 8 and the box body 1. The groove openings of each receiving groove 15 are parallel to the first direction X, and a plurality of cavities 3 are arranged in the receiving groove 15; wherein, the second direction Z is the height direction of the box body 1.

[0052] In this embodiment, if Figure 1 、 Figure 9 and Figure 11 As shown, the staff installs the electronic module 10 in the receiving slot 15 from the slot. Each receiving slot 15 is installed with an electronic module 10. A plurality of cavities 3 are provided in the receiving slot 15. The extrusion blocks 7 on the plurality of cavities 3 are squeezed on the electronic module 10 to fix the electronic module 10 in the receiving slot 15. The electronic module 10 is fixed at multiple points to improve the fixing effect.

[0053] In some embodiments, as Figure 1 、 Figure 9 and Figure 11 As shown, multiple cavities 3 are provided on both side walls of the accommodating groove 15. After the door panel 2 is closed, the extrusion blocks 7 on the cavities 3 on both sides pressurize the electronic module 10 at the same time, thereby achieving multi-point fixation of the electronic module 10.

[0054] In one implementation, Figure 9 、 Figure 10 and Figure 11 As shown, the installation component 8 includes: a trough body 801 and a mounting frame 802. Specifically, the trough body 801 is connected to the box body 1, and the trough body 801 passes through along the first direction X; the mounting frame 802 is arranged in the trough body 801, and a first gap 16 is set between the mounting frame 802 and the bottom plate of the trough body 801, and a plurality of rollers 803 are rotatably arranged on the mounting frame 802, and the plurality of rollers 803 are suitable for rolling and abutting with the bottom of the electronic module 10.

[0055] In this embodiment, if Figure 9 、 Figure 10 and Figure 11As shown, the trough body 801 is arranged in the box body 1 at intervals along the second direction Z, the mounting frame 802 is arranged in the trough body 801, and the mounting frame 802 is provided with a roller 803. When installing or removing the electronic module 10, the roller 803 rolls and abuts against the bottom of the electronic module 10, making installation or removal easier and reducing the wear on the bottom of the electronic module 10 during installation or removal. A first gap 16 is set between the mounting frame 802 and the bottom plate of the trough body 801, which can improve the heat dissipation effect of the electronic module 10.

[0056] In one implementation, Figure 3 、 Figure 10 and Figure 11 As shown, a accommodating cavity 8011 is provided in the groove wall of the groove body 801, and the accommodating cavity 8011 is connected with the corresponding multiple cavities 3. The accommodating cavity 8011 contains a pressure transmission medium. The bottom plate of the groove body 801 is elastic, and a second gap 24 is provided on the mounting frame 802. The bottom plate of the groove body 801 expands under the action of the pressure transmission medium and can pass through the second gap 24 to abut against the bottom of the electronic module 10.

[0057] In this embodiment, if Figure 3 、 Figure 10 and Figure 11 As shown, multiple cavities 3 in a receiving groove 15 are connected to the corresponding receiving cavity 8011, and the receiving cavity 8011 is filled with a pressure transmission medium. When the door panel 2 is closed, multiple filling blocks 6 are simultaneously inserted into the corresponding elastic tube 4, and the volume of the elastic tube 4 increases, thereby increasing the pressure of the pressure transmission medium in the cavity 3. The pressure in the receiving cavity 8011 is the same as the pressure in the cavity 3, causing the bottom plate of the groove body 801 to expand. Part of the bottom plate of the groove body 801 passes through the second gap 24 and abuts against the bottom of the electronic module 10, and there is pressure between them, which can further fix the electronic module 10 and improve the stability of the electronic module 10 installed in the box body 1; at the same time, part of the bottom plate of the groove body 801 abuts against the bottom of the electronic module 10, and the pressure transmission medium can take away the heat of the electronic module 10, thereby improving the heat dissipation effect of the electronic module 10.

[0058] In some embodiments, as Figure 2 and Figure 7 As shown, an outlet is provided on the cavity 3 , and an inlet communicating with the accommodating cavity 8011 is provided on the groove body 801 , and the outlet and the inlet are communicated through the infusion tube 23 .

[0059] Specifically, such as Figure 10 As shown, the bottom plate of the tank body 801 is a rubber sheet 804 .

[0060] In one implementation, Figure 11As shown, the mounting frame 802 includes: multiple support rods 8021, each of which extends along the third direction Y and has both ends connected to the side walls of the trough body 801, and the multiple support rods 8021 are arranged at intervals along the first direction X, and the gap between two adjacent support rods 8021 is the second gap 24, and multiple rollers 803 are rotatably connected to the multiple support rods 8021.

[0061] In this embodiment, if Figure 9 As shown, multiple support rods 8021 are connected to the slot body 801, and each support rod 8021 is rotatably connected to multiple rollers 803, and the tops of the multiple rollers 803 along the second direction Z are in the same plane, ensuring that each roller 803 is in contact with the bottom of the electronic module 10.

[0063] In this embodiment, the heat dissipation effect of the electronic module 10 is further improved.

[0064] In one implementation, Figure 1 、 Figure 12 and Figure 13 As shown, the heat dissipation assembly 9 includes: at least one air duct 901 and at least one heat conducting plate 903. Specifically, the at least one air duct 901 is disposed on the outer wall of the housing 1. One end of the air duct 901 is adapted to connect to a gas delivery device, and the other end is provided with an exhaust valve 902. The sidewall of the air duct 901 is provided with at least one fourth through hole. The housing 1 is provided with a first through hole corresponding to the fourth through hole. The tank 801 is provided with a first via hole corresponding to the first through hole. The first via hole is connected to the accommodating cavity 8011. The heat conducting plate 903 extends through the fourth through hole, the first through hole, and the first via hole in sequence.

[0065] In this embodiment, if Figure 1 、 Figure 12 and Figure 13 As shown, the gas delivery device provides gas to the air pipe 901, and an exhaust valve 902 is provided at the other end of the air pipe 901. When the air pressure in the air pipe 901 reaches the rated pressure, the exhaust valve 902 automatically opens, and the heat conducting plate 903 passes through the fourth through hole, the first through hole and the first through hole in sequence. A part of the heat conducting plate 903 is arranged in the air pipe 901, and a part is arranged in the accommodating cavity 8011 and contacts the pressure transmission medium. The pressure transmission medium exchanges heat with the electronic module 10 through the bottom plate of the slot body 801. The heat conducting plate 903 transfers the heat of the pressure transmission medium to the air pipe 901. When the exhaust valve 902 is opened, the heat on the heat sink is discharged.

[0066] In some embodiments, as Figure 1As shown, a plurality of air guide tubes 901 are provided, and an air guide tube 901 is provided on both sides of each slot body 801 .

[0067] In some embodiments, as Figure 12 and 13 As shown, a plurality of heat conducting sheets 903 are provided, and a plurality of heat conducting sheets 903 are provided in each air guide tube 901 .

[0068] In one implementation, Figure 10 、 Figure 12 and Figure 13 As shown, the heat dissipation assembly 9 also includes: at least one spoiler 904, at least one pneumatic rod assembly 905 and at least one second elastic assembly 906. Specifically, at least one spoiler 904 is arranged in the accommodating cavity 8011, and the spoiler 904 is provided with a guide groove, which is slidably connected to the heat conducting plate 903; at least one pneumatic rod assembly 905 is arranged in the air duct 901, and the piston rod of the pneumatic rod assembly 905 passes through the box body 1 and the tank body 801 and is connected to the spoiler 904, and the gas in the air duct 901 can enter and exit the air hole of the pneumatic rod assembly 905 to drive the piston rod of the pneumatic rod assembly 905 to extend and retract; at least one second elastic assembly 906 is arranged in the accommodating cavity 8011, one end of the second elastic assembly 906 is connected to the spoiler 904, and the other end is connected to the tank body 801. Under the elastic force of the second elastic assembly 906, the spoiler 904 has a tendency to approach the air duct 901 along the third direction Y.

[0069] In this embodiment, if Figure 10 、 Figure 12 and Figure 13 As shown, when the air pressure in the air duct 901 increases but has not yet reached the rated air pressure, the gas enters the pneumatic rod assembly 905 from the air hole, drives the piston rod of the pneumatic rod assembly 905 to extend, and pushes the spoiler 904 to move along the third direction Y away from the air duct 901. In this process, the guide groove of the spoiler 904 is slidably connected to the heat conducting plate 903, which can limit the moving direction of the spoiler 904, so that the plate surface of the spoiler 904 is perpendicular to its moving direction, thereby increasing the contact area with the pressure transmission medium in its moving direction. When the air pressure in the heat pipe reaches the rated air pressure, the exhaust valve 902 opens, and the rated air pressure is adjustable from 0.3 MPa to 0.7 MPa. The gas in the air pipe 901 is discharged, and the air pressure in the air pipe 901 is reduced. The piston rod of the gas rod assembly 905 retracts, and the second elastic assembly pushes the spoiler 904 in the direction close to the air pipe 901. The spoiler 904 moves in the accommodating cavity 8011 and disturbs the pressure transmission medium in the accommodating cavity 8011, so that the temperature of the pressure transmission medium in the accommodating cavity 8011 is more uniform, further improving the heat dissipation effect of the electronic module 10.

[0070] In some embodiments, as Figure 10 and Figure 14 As shown, the heat dissipation assembly 9 also includes at least one pipe fitting 909, one end of which is sealed, and at least one third through hole is provided on the side wall of the air guide tube 901.

A water absorbing member 910 is provided in the pipe fitting 909, and the water absorbing member 910 is provided at the open end of the pipe fitting 909.

[0071] Specifically, the water absorbing member 910 is a water absorbing sponge or a desiccant such as quicklime or calcium chloride.

[0072] In some embodiments, as Figure 13 As shown, the pipe 909 extends along the third direction Y, and a second guide hole is opened on the spoiler 904, and the second guide hole is slidably connected to the pipe 909.

[0073] In some embodiments, the tube 909 is a square tube.

The breathable section 9092 is provided in the air guide tube 901 and includes two branch tubes 90921. The two branch tubes 90921 are respectively connected to the fixed section 9091 and the guide section 9093, and a third gap 20 is provided between the two branch tubes 90921 to facilitate the passage of gas in the air guide tube 901. The guide section 9093 is provided in the accommodating cavity 8011.

[0075] In some embodiments, as Figure 10 and 12 and Figure 13 As shown, the gas pressure rod assembly 905 and the second elastic assembly 906 are both provided in plurality.

[0076] In some embodiments, as Figure 10 and Figure 13 As shown, the second elastic component 906 includes a second spring 9061 and a fixing plate 9062. The fixing plate 9062 is arranged in the accommodating cavity 8011 and fixed on the cavity wall of the accommodating cavity 8011. The two ends of the second spring 9061 are respectively connected to the spoiler 904 and the fixing plate 9062.

[0077] Specifically, the pneumatic rod assembly 905 includes a second cylinder body, a second piston and a second piston rod. The second piston is sealingly and slidingly connected to the second cylinder body. One end of the second piston rod is connected to the second piston, and the other end is connected to the spoiler 904. A rodless cavity is formed between the second piston and the second cylinder body. An air hole is opened on the second cylinder body, and the air hole is connected to the rodless cavity.

[0078] Specifically, the pneumatic rod assembly 905 can be a pneumatic telescopic rod in the related art.

[0079] In one implementation, Figure 1 As shown, the heat dissipation component 9 also includes an air pump 907 and a connecting pipe 908. Specifically, the air pump 907 is arranged on the box body 1; one end of the connecting pipe 908 is sealed, and the other end is connected to the air pump 907, and a plurality of air outlets are provided on the connecting pipe 908; the heat dissipation component 9 is provided with a plurality of air guide pipes 901, one end of which is away from the exhaust valve 902 and is connected to the plurality of air outlets in a one-to-one correspondence.

[0080] In this embodiment, if Figure 1 As shown, air guide tubes 901 are provided on both sides of each trough body 801, and the connecting tube 908 is a U-shaped tube. One end of the U-shaped tube is connected to the air pump 907, and the other end is sealed. In addition, a plurality of air outlets are provided on the U-shaped tube, and the plurality of air outlets are respectively connected to a plurality of air guide tubes 901 in a one-to-one correspondence, and the plurality of air guide tubes 901 are connected at the same time through one U-shaped tube.

[0081] On the other hand, an electronic device is provided, such as Figure 1 、 Figure 3 and Figure 4 Shown, including: The chassis, the back panel of the box body 1 is provided with a quick plug-in docking head 17 and a quick plug-in connector 18 for electrical connection; The electronic module 10 is provided with a connection groove 19 corresponding to the extrusion block 7 , and the extrusion block 7 can be inserted into the connection groove 19 to limit the movement of the electronic module 10 along the first direction X; the quick-plug connector 17 can be electrically connected to the electronic module 10 .

[0082] In this embodiment, if Figure 1 、 Figure 3 and Figure 4As shown, an opening is provided on one side of the box body 1. The electronic module 10 is placed into the box body 1 from the opening. The door panel 2 is rotated. The door panel 2 can abut against the extrusion frame 5 before the opening is completely closed. As the door panel 2 is completely closed, the door panel 2 slides against the extrusion frame 5. The door panel 2 drives the extrusion frame 5 to move along the first direction X. The extrusion frame 5 slides through the multiple elastic tubes 4 in sequence along the first direction X. The multiple filling blocks 6 can simultaneously penetrate into their corresponding elastic tubes 4. Before the filling blocks 6 enter the elastic tubes 4, the elastic tubes 4 are compressed under the pressure of the pressure transmission medium. As the door panel 2 is closed, the multiple filling blocks 6 simultaneously penetrate into the corresponding elastic tubes 4. Inside the tube 4, the volume of the elastic tube 4 increases, increasing the pressure of the pressure transmission medium in the cavity 3. The pressure transmission medium enters the rodless cavity of the hydraulic rod assembly 12 from the liquid hole, pushing its piston rod to extend. The piston rod pushes the extrusion block 7 to extend out of the cavity 3 along the axial direction of the second through hole. The extrusion block 7 is inserted into the connecting groove 19 and is squeezed and abutted against the bottom of the connecting groove 19. An installation groove is provided on the side of the extrusion block 7, and a thermal expansion block 11 is provided in the installation groove. After the electronic module 10 has worked for a period of time, the temperature rises. After the temperature of the thermal expansion block 11 reaches the threshold temperature, it expands, extends out of the installation groove, and abuts and presses against the groove wall of the connecting groove 19. When the door panel 2 is opened, the door panel 2 loses pressure on the extrusion frame 5. Under the pressure of the pressure transmission medium, the filling block 6 is squeezed out of the elastic tube 4, or the staff pulls the extrusion frame 5 to pull the filling block 6 out of the elastic tube 4. At the same time, the first elastic component 13 applies a pulling force to the extrusion block 7 to pull it back into the cavity 3, but the thermal expansion block 11 is pressed against the groove wall of the connecting groove 19, and the extrusion block 7 cannot retract into the cavity 3, preventing the staff from removing the electronic module 10 before the temperature of the electronic module 10 drops below the threshold temperature and scalding the staff.

[0083] When the temperature of the electronic module 10 drops below the threshold temperature, the thermal expansion block 11 retracts into the installation groove, the thermal expansion block 11 is away from the groove wall of the connecting groove 19, and the extrusion block 7 retracts into the cavity 3, away from the electronic module 10. At this time, the staff can take the electronic module 10 out of the box 1 for replacement or repair.

[0084] In some embodiments, the driving force Fhyd of the hydraulic rod assembly 12 and the pressure transmission medium satisfy the following functional relationship: Fhyd=ΔP×Apiston; wherein ΔP is the pressure increment of the pressure transmission medium, and Apiston is the piston cross-sectional area of ​​the hydraulic rod assembly 12.

[0085] ΔP=pfill+(β / V0)ΔV, where pfill is the initial filling pressure of the pressure transmission medium, ΔV is the volume change of the elastic tube 4, β is the liquid compression modulus, and V0 is the initial volume of the pressure transmission medium.

[0086] Specifically, when pfill=100000Pa; V0=0.001 m 3 , ΔV=0.00002 m 3 ; β = 2.0 × 10 9 Pa; Apisiton=0.01 m 2 ; At this time, Fhyd=401000N.

[0087] In some embodiments, the functional relationship between the friction force Ffric(T) between the thermal expansion block 11 and the connection groove 19 and the temperature is: Ffric(T)=μ(T)×N(T); where μ(T) is the friction coefficient at temperature T; N(T) is the normal pressure generated by expansion at temperature T.

[0088] μ(T)=μ0+α(T-T0), where T0 is the reference temperature (such as room temperature 25°C), μ0 is the friction coefficient at the reference temperature T0, α is the temperature coefficient, and T is the current operating temperature.

[0089] N(T)=kexp×(T-Tact), where Tact is the activation temperature threshold of the thermal expansion block 11, and kexp is the thermal expansion coefficient.

[0090] Specifically, μ0=0.25; α=0.002; T0=25; kexp=120; Tact=40.

[0091] When T=30℃, Ffric=0.26×0=0N.

[0092] When T=45℃, Ffric=0.29×600=174N.

[0093] When T=70℃, Ffric=0.34×3600=1224N.

[0094] In some embodiments, the restoring force provided by the spring-type telescopic rod is Fspring=kspring×(X0+ΔX), where X0 is the initial length of the spring-type telescopic rod, ΔX is the deformation of the spring-type telescopic rod, and kspring is the spring coefficient of the spring-type telescopic rod.

[0095] Specifically, when kspring = 500 N / m, X0 = 0.02 m, and ΔX = 0.03 m, Fspring = 500 × (0.02 + 0.03) = 500 × 0.05 = 25 N.

[0096] The system equilibrium condition (when the door is closed) is Fhyd+Ffric(T)≥Fspring+Fload, where Fload is an external load such as vibration of the electronic module 10 .

[0097] The above specific parameters are only virtual parameters used for calculation and display. The specific situation shall be subject to the specific parameters of the relevant parts of the application.

[0098] Although the embodiments of the present application are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present application, and such modifications and variations shall fall within the scope defined by the accompanying application.
