Description

Technical Field

[0001] The invention relates to the field of electronic equipment transportation, in particular to a chassis and electronic equipment. Background Art

[0002] As servers have higher and higher requirements for graphics processing and data storage capabilities, the number and weight of GPUs (Graphics Processing Units) and hard disks in electronic devices are also increasing. As the weight of electronic equipment chassis increases, higher requirements are placed on the reliability level of chassis transportation.

[0003] The ear structure of the chassis refers to the protruding structure specially added on the side panel of the chassis, which is used to connect the chassis with other equipment or facilities; the ear structure of the chassis is usually made of metal materials, which can enhance the stability and load-bearing capacity of the chassis. At present, the design of the packaging material used to install the chassis is independent of the design of the ear on the chassis, and the existence of the ear has the most important influence on the morphology of the packaging material: on the one hand, the ear as an independent component is exposed outside the entire chassis, and the packaging material needs to be designed with a larger clearance size to avoid the ear, so as to prevent the ear from hitting the packaging material during transportation and causing the ear to be damaged and ineffective; on the other hand, the large clearance size of the ear causes the packaging material in this direction to become thinner, which objectively forms a pair of contradictions that are mutually generated but difficult to resolve: the ear as a key component must be guaranteed to be absolutely safe, but the packaging material that can provide effective protection near the ear is the weakest position in the entire packaging material.

[0004] In the related art, in order to provide effective protection for the box ears, the thickness of the packaging material can only be greatly increased in other directions. The increase in the size of the packaging material causes the outer size of the packaging box to increase as well. The increase in both sizes significantly increases the amount and cost of the packaging material, and the increase in the outer size will also lead to an increase in the storage cost of the packaging box.

[0041] In this embodiment, the chassis includes a detachable chassis ear 1 and a chassis body 2. The chassis ear 1 and the chassis body 2 are in a detached state during transportation. When they need to be used, the chassis ear 1 and the chassis body 2 can be assembled, which does not affect the normal connection function of the chassis ear 1 and can enhance the stability and carrying capacity of the chassis body 2.

[0042] The case also includes a quick release mechanism 3, which is connected between the case ear 1 and the case body 2. The quick release mechanism 3 is used to realize the quick disassembly and installation of the case ear 1 and the case body 2, thereby ensuring the efficiency of disassembly and installation.

[0043] A conducting part 11 is provided on the case ear 1, and a case transmission connector 22 is provided on the case body 2. The case transmission connector 22 is adapted to the conducting part 11. The case transmission connector 22 may be a PCB (Printed Circuit Board) board, and a gold finger is provided on the PCB board.

The case transmission connector 22 may also be inserted into the conducting part 11 to achieve conduction connection between the two. A display or a switch button may be provided on the case ear 1, and then the connection with the main board inside the case body 2 is achieved through conduction between the conducting part 11 and the case transmission connector 22. Specifically, the PCB board is fixedly connected to the case body 2, and a PCIE (peripheral component interconnect express) or a module connector is provided at a position corresponding to the case ear 1, so that data connection can be conveniently achieved by plugging and unplugging.

Furthermore, all information that can be displayed on the box ear 1 is transmitted from the motherboard inside the chassis body 2, such as the power on / off button and the restart button set on the box ear 1.

[0045] Specifically, the chassis can be a chassis of an electronic device, for example, a server chassis or a switch chassis. The quick release mechanism 3 can be fixed on the chassis ear 1. The quick release mechanism 3 and the chassis ear 1 together constitute a chassis ear module, and the chassis ear module is stored separately as a whole.

[0046] The chassis provided by the present invention has a split design for the chassis ear 1 and the chassis body 2, so that the two can be disassembled during transportation and can be installed and combined together when needed; since the chassis ear 1 can be plugged in and out as a whole, the packaging material 6 is no longer needed to design an air-avoiding space for the chassis ear 1 after the chassis ear 1 is pulled out, so that the packaging material 6 can increase the thickness in the direction of weak strength, which significantly improves the reliability level of the chassis during transportation; since the chassis ear 1 does not need to be designed with an air-avoiding dimension during transportation, the packaging material 6 does not need to increase the thickness in other directions to ensure the overall safety, the size of the packaging material 6 and the packaging box is reduced, the cost is reduced, and the storage cost of the packaging material 6 is also reduced; the chassis ear 1 is a detachable independent part The components are placed in the accessory box, and the accessory box is placed in the packaging material 6 for storage and transportation, which greatly improves the reliability level of the box ear 1; because the box ear 1 is designed as a modular system, electronic devices of the same height such as 1U / 2U / 4U can uniformly use the same box ear 1, saving costs; the box ear 1 is disassembled and assembled with the chassis body 2 through the quick-release mechanism 3, which can ensure the installation strength between the box ear 1 and the chassis body 2 while facilitating disassembly and assembly; and the lead-out wires of the box ear 1 and the chassis body 2 are connected by means of the chassis transmission connector 22 and the conductive part 11, and the chassis transmission connector 22 can use PCB gold fingers to ensure the signal transmission between the chassis body 2 and the box ear 1, so as to realize the normal design function of the box ear 1. The chassis provided by the present invention can remove the box ear 1 and the quick-release mechanism 3 as a whole during normal packaging, transportation, and experimentation, and the box ear 1 is placed in the accessory box as an accessory, eliminating the avoidance space for the box ear 1 in the packaging material 6 in the related art, which can greatly increase the thickness of the packaging material 6, so that the transportation reliability level of the chassis is greatly improved.

[0047] In some embodiments, the quick release mechanism 3 includes a rotating shaft 31 and a hook 32. The rotating shaft 31 is installed on one of the case ear 1 and the chassis body 2. The rotating shaft 31 can be a metal rotating shaft 31. The case ear 1 or the chassis body 2 is provided with a rotating shaft 31 assembly hole. One end of the rotating shaft 31 is installed in the rotating shaft 31 assembly hole, and the other end is hinged to the hook 32. A clamping platform is provided at the end of the rotating shaft 31 to prevent the hook 32 from falling out; the case ear 1 and the other of the chassis body 2 are provided with a clamping groove to form a clamping portion 21, and the hook 32 is engaged with the clamping portion 21 to lock or unlock the case ear 1 and the chassis body 2; specifically, the clamping groove is a blind groove, and the clamping groove is in a strip shape. The width of the clamping groove is slightly larger than the width of the hook 32, so as to ensure that the hook 32 enters the clamping groove.

[0048] In some embodiments, the quick release mechanism 3 also includes an elastic component 33, which is installed on one of the case ear 1 and the chassis body 2 where the quick release mechanism 3 is arranged, and the elastic component 33 can reset the hook 32 to lock the case ear 1 and the chassis body 2; specifically, the elastic component 33 can be selected as a spring, which is easy to install and has a good reset effect; when the quick release mechanism 3 is installed on the case ear 1, the elastic component 33 is installed on the case ear 1, and when the quick release mechanism 3 is installed on the chassis body 2, the elastic component 33 is installed on the chassis body 2, that is, the elastic component 33 is installed on the same main body as the rotating shaft 31 and the hook 32, thereby ensuring the stability of the hook 32 and facilitating arrangement.

[0049] In some embodiments, the elastic component 33 is installed on the rotating shaft 31 and is in a pre-twisted state. The hook 32 is reset by resetting the rotating shaft 31. In this setting, the rotating shaft 31 and the hook 32 are fixedly connected, and the rotating shaft 31 and the case ear 1 or the case body 2 are hinged; or, the elastic component 33 is installed on the side of the hook 32 away from the engaging groove and is in a pre-compression state. The compression force of the elastic component 33 is used to provide a reaction force for the hook 32 to push the hook 32 into the engaging groove to achieve engaging; or, the elastic component 33 is installed on the side of the hook 32 close to the engaging groove and is in a pre-stretched state. The stretching force of the elastic component 33 is used to provide a reaction force for the hook 32 to pull the hook 32 into the engaging groove to achieve engaging; the above-mentioned methods are all for achieving the position change of the hook 32, so as to meet the purpose of engaging with the engaging groove. Any setting method that can achieve the above-mentioned effect is acceptable and is not limited to the method given in this embodiment.

[0050] In some embodiments, the quick release mechanism 3 also includes a plate body 34, which is installed on the case ear 1, and the rotating shaft 31 and the hook 32 are installed on the plate body 34, and the plate body 34 is provided with a horizontal bending limit portion 341 that is compatible with the step portion 23 of the chassis body 2, the clamping portion 21 is located on the step portion 23 of the chassis body 2, and the horizontal bending limit portion 341 separates the plate body 34 into a first plate surface 342 and a second plate surface 343 that are staggered, and the rotating shaft 31 and the hook 32 are installed on the second plate surface 343.

[0051] The above-mentioned arrangement, through the arrangement of the plate body 34, with the help of the horizontal bending limit portion 341 and the cooperation with the step portion 23 of the chassis body 2, can not only preliminarily locate the position of the plate body 34, thereby facilitating the assembly of the case ear 1, but also the arrangement of the horizontal bending limit portion 341 can facilitate the formation of a staggered layer between the first plate surface 342 and the second plate surface 343, facilitate the arrangement of the rotating shaft 31 and the hook 32, and is beneficial to the limiting cooperation between the hook 32 and the clamping portion 21 on the chassis body 2, which is beneficial to improving the disassembly and assembly efficiency of the case ear 1.

[0052] In some embodiments, a connecting rod 3411 is provided on the horizontal bending limit portion 341, one end of the elastic component 33 is connected to the connecting rod 3411, and the other end is connected to the hook 32, and the end of the hook 32 facing away from the rotating shaft 31 is provided with a clamping end 321, and the clamping end 321 can be inserted into the clamping groove, and the elastic component 33 is connected between the clamping end 321 and the rotating shaft 31.

[0053] In some embodiments, an electromagnet is further included, which is mounted on the plate body 34, and a magnetic structure is provided on the side of the hook 32 away from the clamping end 321; the electromagnet is connected to the conducting portion 11 in the box ear 1, and when the box ear 1 is assembled with the chassis body 2, the conducting portion 11 of the box ear 1 is connected to the mainboard in the chassis body 2, and the mainboard in the chassis body 2 supplies power to the conducting portion 11 of the box ear 1, and the conducting portion 11 of the box ear 1 can supply power to the electromagnet; further, an unlocking button is also provided on the box ear 1, and when the unlocking button is triggered, the conducting portion 11 of the box ear 1 supplies power to the electromagnet, and the electromagnet absorbs the magnetic structure of the hook 32, so that the clamping end 321 is separated from the clamping slot, as shown in FIG. Figure 6 As shown, at this time, the box ear 1 is pulled to separate the box ear 1 from the chassis body 2, and the power is cut off after the conductive part 11 of the box ear 1 is separated from the chassis body 2, and the electromagnet is automatically powered off; when the unlocking button is not triggered, the conductive part 11 of the box ear 1 will not supply power to the electromagnet, and the electromagnet cannot absorb the magnetic structure of the hook 32, and maintain the locked state, as shown in FIG. Figure 5 shown.

[0054] In some embodiments, the plate body 34 is further provided with a vertical bending limiter 344, the first side A of the plate body 34 is fixedly connected to the box ear 1, the second side B is detachably connected to the chassis body 2, the first side A is perpendicular to the second side B, and the plate body 34 is provided, due to the large area of ​​the plate body 34, the connection between the plate body 34 and the box ear 1 is stable, and at the same time, the positioning between the plate body 34 and the chassis body 2 is convenient and the assembly is firm; specifically, the first side A and the box ear 1 can be connected by screws or fixed by welding, and the second side B and the chassis body 2 are locked or unlocked by the hook 32, and when the hook 32 is locked with the chassis body 2, the second side B of the plate body 34 can also be fixed to the chassis body 2 by a fastener. Of course, the first side A of the plate body 34 can also be fixedly connected to the chassis body 2, and the second side B can be detachably connected to the box ear 1; since the size of the box ear 1 is small and convenient to store, it is better to set the quick release mechanism 3 on the box ear 1.

[0055] In some embodiments, the plate body 34 is also provided with an avoidance hollow portion 345 for checking the position of the chassis transmission connector 22. The avoidance hollow portion 345 extends to the first side surface A and the second side surface B, and extends to the first plate surface 342 and the second plate surface 343 on the second side surface B, that is, the avoidance hollow portion 345 is arranged at the connection between the vertical bending limit portion 344 and the horizontal bending limit portion 341. By setting the avoidance hollow portion 345, not only the chassis transmission connector 22 can be avoided, which facilitates the judgment of whether the moving position of the box ear 1 is accurate, but also the setting of the horizontal bending limit portion 341 can be facilitated to avoid the interference between the positions of the vertical bending limit portion 344 and the horizontal bending limit portion 341, thereby ensuring the smooth processing and forming of the plate body 34; specifically, the plate body 34 can be processed and formed by bending and cutting, or it can be cast as an integral part, whichever method is convenient for processing.

[0056] In some embodiments, please refer to Figure 5 and Figure 6 The first side surface A of the plate body 34 is perpendicular to the second side surface B. The horizontal bending limit portion 341 is located on the second side surface B and divides the second side surface B into a first plate surface 342 and a second plate surface 343. The first plate surface 342 and the second plate surface 343 are arranged in the longitudinal direction, and the first plate surface 342 and the second plate surface 343 are located on different planes. The first plate surface 342 and the second plate surface 343 are respectively arranged on the two side surfaces of the step portion 23 of the chassis body 2. The cooperation of the part 23 can achieve preliminary limiting. The edge of the second side surface B is also provided with a plurality of assembly holes 346 for assembly and fixation with the chassis body 2. Screws and other fasteners can be set in the assembly holes 346 to fix the second side surface B to the chassis body 2. Specifically, the first plate surface 342 and the second plate surface 343 are both provided with assembly holes 346. The assembly holes 346 can be set at the corners of the second side surface B in the plate body 34 to improve the firmness between the second side surface B of the plate body 34 and the chassis body 2.

[0057] Furthermore, the hook 32 is a metal part with high strength, not easy to deform, and long service life. The hook 32 can be U-shaped. The first leg 322 of the hook 32 is connected to the rotating shaft 31. The first leg 322 of the hook 32 can be hinged to the rotating shaft 31, or can be hinged to the plate body 34 after being fixedly connected to the rotating shaft 31. The outer end of the second leg 323 constitutes a clamping end 321, that is, the outer end of the second leg 323 can rotate around the rotating shaft 31 to achieve locking and unlocking with the clamping portion 21. The U-shaped setting of the hook 32 is to facilitate the setting of a folded edge 324 in the middle of the hook 32. The elastic component 33 is hung on the folded edge 324 to ensure the stability of the elastic component 33. In addition, the setting of the hook 32 with a U-shaped structure makes it easy to arrange the elastic component 33, which occupies a small space and has a good use effect.

[0058] The clamping end 321 is suspended on the outside of the plate body 34. A guide slope 325 is provided on the side of the clamping end 321 away from the rotating shaft 31. The guide slope 325 is inclined from the side close to the rotating shaft 31 to the other side in a direction away from the clamping portion 21. The setting of the guide slope 325 is to achieve automatic assembly. When the case ear 1 is close to the case body 2, the hook 32 can automatically rotate under the action of the guide slope 325, which is convenient for operation.

[0059] When the case ear 1 and the case body 2 are assembled, the case ear 1 moves toward the direction close to the case body 2, and the guide slope 325 abuts against the step portion 23 of the case body 2 to push the guide slope 325 to rotate around the rotating shaft 31 and pull the elastic component 33 to extend. After the guide slope 325 is completely inserted into the clamping groove, the clamping end 321 is clamped with the clamping portion 21 under the elastic force of the elastic component 33;

[0060] When the case ear 1 and the case body 2 are separated, the hook 32 is rotated until the clamping end 321 is disengaged from the clamping groove, and the case ear 1 is moved in the opposite direction, and the clamping end 321 abuts against the step portion 23 of the case body 2 again until the clamping end 321 is separated from the case body 2. Under the action of the elastic component 33, the side of the clamping end 321 facing away from the guide slope 325 abuts against the side wall of the horizontal bending limit portion 341.

[0061] In some embodiments, a rivet 4 is provided on at least one of the case ear 1 and the case body 2. The rivet 4 can be a metal rivet 4 with high strength. A limit platform is provided on the rivet 4 to prevent it from falling off. A limit guide hole 5 is provided on the quick release mechanism 3. The limit guide hole 5 includes an avoidance portion 51 and a limit portion 52 that are interconnected. The size of the avoidance portion 51 is larger than the size of the limit platform, and the size of the limit portion 52 is smaller than the size of the limit platform. The rivet 4 enters the limit guide hole 5 from the avoidance portion 51 and slides into the limit portion 52. Specifically, the number of the limiting guide holes 5 can be multiple, and pull nails 4 are provided on both sides of the step portion 23 of the chassis body 2, and limiting guide holes 5 are provided on the first plate surface 342 and the second plate surface 343. By limiting two different positions of the plate body 34, the positioning accuracy is guaranteed; the limiting portion 52 is a strip structure, and the avoidance portion 51 is located at the end of the limiting portion 52 away from the box ear 1. The limiting portion 52 acts as a slide, and the pull nail 4 slides in the limiting portion 52, so that the conducting portion 11 of the box ear 1 and the chassis transmission connector 22 of the chassis body 2 are successfully connected.

[0062] Specifically, in a specific embodiment, the chassis includes a chassis ear 1, a chassis body 2 and a quick-release mechanism 3, the quick-release mechanism 3 is connected between the chassis ear 1 and the chassis body 2, the quick-release mechanism 3 is installed on the chassis ear 1, and the chassis body 2 is provided with a clamping portion 21; the chassis ear 1 is provided with a conducting portion 11, and the chassis body 2 is provided with a chassis transmission connector 22, and the chassis transmission connector 22 is adapted to the conducting portion 11; the quick-release mechanism 3 includes a plate 34, a rotating shaft 31 and a hook 32, the plate 34 is installed on the chassis ear 1, and the rotating shaft 31 and the hook 32 are installed on the plate 34; the plate 34 is provided with a horizontal bending limit portion 341 adapted to the step portion 23 of the chassis body 2, the clamping portion 21 is located on the step portion 23 of the chassis body 2, and the horizontal bending limit portion 341 separates the plate 34 The first plate surface 342 and the second plate surface 343 are arranged in a staggered manner, and the rotating shaft 31 and the hook 32 are installed on the second plate surface 343; a vertical bending limit portion 344 is also provided on the plate body 34, the first side surface A of the plate body 34 is fixedly connected to the case ear 1, and the second side surface B is detachably connected to the chassis body 2; the quick-release mechanism 3 also includes an elastic component 33, and the elastic component 33 is installed on the plate body 34; a connecting rod 3411 is provided on the horizontal bending limit portion 341, and one end of the elastic component 33 is connected to the connecting rod 3411; the hook 32 is U-shaped, including a first leg 322 that can be hinged to the rotating shaft 31, and the outer end of the second leg 323 constitutes a clamping end 321, a folded edge 324 is provided in the middle of the hook 32, and the other end of the elastic component 33 is connected to the folded edge 324 of the hook 32.

[0063] Further, when the box ear module needs to be assembled with the chassis body 2, the box ear module is moved toward the chassis body 2, and the limiting guide hole 5 of the plate body 34 in the box ear module is aligned with the position of the rivet 4, until the avoidance portion 51 is pulled into the limiting guide hole 5, and then the plate body 34 is fitted with the surface of the chassis body 2, and the plate body 34 is pushed into the plate body 34 according to the predetermined position of the limiting portion 52. The rivet 4 can provide limiting in all directions of freedom except toward the avoidance portion 51;

[0064] When the box ear module is pushed, the guide bevel 325 of the hook 32 will abut against the step portion 23 of the chassis body 2, so that the hook 32 rotates around the rotating shaft 31 and stretches the elastic component 33. In the process of pushing the box ear module, the guide bevel 325 of the hook 32 gradually approaches the engaging groove. When the guide bevel 325 of the hook 32 enters the engaging groove completely, under the action of the elastic component 33, the guide bevel 325 of the hook 32 enters the engaging groove, so that the engaging end 321 of the hook 32 engages with the side wall of the engaging groove. At this time, the rivet 4 just moves to the end of the limiting portion 52 away from the avoiding portion 51, and the box ear module cannot be pushed further, so that the box ear module is limited in all directions of freedom. At this time, the normal use operation of the chassis can be carried out.

[0065] When the chassis needs to be transported, the chassis ear module is separated from the chassis body 2. First, the fastener in the assembly hole 346 is removed, and then the hook 32 is rotated in the opposite direction manually or with the help of other structures, so that the clamping end 321 of the hook 32 is separated from the side wall of the clamping groove. At this time, the chassis ear module can be away from the chassis body 2. Under the action of the limiting guide hole 5, the chassis ear module is smoothly separated from the chassis body 2 until the position of the rivet 4 corresponds to the avoidance portion 51 of the limiting guide hole 5. At this time, the plate 34 of the quick-release mechanism 3 in the chassis ear module can be separated from the chassis body 2. Through the mutual cooperation of the hook 32 and the rivet 4, the chassis ear module and the chassis body 2 can be quickly disassembled and locked.

[0066] Since the chassis provided by the present invention has a detachable chassis ear 1, the packaging material 6 of the chassis can fully and effectively utilize the space. Figure 7 As shown, the need to open a large avoidance space on the packaging material 6 due to the limitation of the structure of the box ear 1 is avoided. By disassembling the box ear module, the shape of the packaging material 6 is more complete, the generation of weak structure is avoided, the effective buffering thickness is significantly increased, and the protective effect on the electronic equipment is significantly enhanced. The structure of the packaging material 6 is simpler, and the overall wrapping of the electronic equipment is better. All positions including the four corners of the chassis are well protected by the packaging material 6, which reduces the transportation cost and significantly improves the reliability.

[0067] The design of the chassis structure makes the structure of the packaging material 6 more concise, and the time cost of designing the packaging material 6 is significantly reduced; the reliability level of the chassis ear module is improved; the passability of the drop reliability test of a single packaging material 6 is improved; the reliability level of electronic equipment transportation is increased; the size and cost of the packaging material 6 are reduced, and the storage cost of the packaging box is reduced; the chassis ear module can be suitable for different chassis, which can reduce the overall cost.
