Abstract
Description
Technical Field
[0001] This application relates to the field of electronic device assembly technology, and more specifically, to electronic devices. Background Technology
[0002] A related technology provides an electronic device comprising electronic components and a mounting bracket. During assembly, the electronic components are assembled into the mounting bracket from top to bottom.
[0003] However, during installation, the electronic components in the related technologies are prone to falling under their own weight, posing a high risk of damage. Utility Model Content
[0004] This application provides an electronic device to address the problem of how to reduce the risk of damage during the installation of electronic devices.
[0005] Embodiments of this application provide an electronic device, including a fixed bracket, an electronic component, and a buffer structure. The fixed bracket has a mounting groove with an opening in a first direction. A through groove is provided on one side of the fixed bracket in a second direction, communicating with the mounting groove and extending along the first direction; wherein the second direction is perpendicular to the first direction. The electronic component is mounted in the mounting groove and has a protrusion that can move within the through groove in the first direction. The buffer structure includes a lifting seat and an elastic member. The lifting seat is movably fitted into the through groove in the first direction, and during insertion of the electronic component into the mounting groove in the first direction, the lifting seat abuts against the side of the protrusion away from the opening in the first direction. The elastic member is disposed between the lifting seat and the fixed bracket and is configured to apply an elastic force to the lifting seat in the first direction toward the side near the opening.
[0006] In the aforementioned electronic device, when the electronic component is inserted into the mounting slot, the protrusion moves along with the electronic component within the slot, thereby pushing the lifting seat within the slot to move away from the slot opening along a first direction. Because the elastic element is located between the lifting seat and the fixed bracket, and can apply an elastic force to the lifting seat in the first direction towards the slot opening, the protrusion experiences resistance towards the slot opening. This provides a buffering effect for the electronic component during installation, preventing it from colliding with the bottom of the mounting slot along the first direction, thus reducing the risk of damage during installation and improving the production yield of the electronic device. For example, during installation, when the first direction is the direction of gravity, the buffering structure can reduce the risk of the electronic component falling and being damaged under its own weight.
[0007] In one embodiment, the elastic element includes a constant-force spring. The elastic element includes a drum portion and a connecting end, the drum portion being rotatably mounted on the outer side of the fixed bracket away from the mounting slot, and the connecting end being connected to the drum portion. The lifting seat is provided with an abutment portion corresponding to the connecting end, and the connecting end is capable of abutting against the abutment portion away from the slot opening in a first direction to apply an elastic force to the lifting seat in the first direction toward the side closer to the slot opening.
[0008] In one embodiment, the buffer structure further includes a mounting base located on the outside of the fixed bracket away from the mounting groove, and the mounting base is situated on the side of the through groove along a third direction. An opening is provided on the side of the mounting base near the through groove; wherein the third direction is perpendicular to both the first and second directions. A drum portion is mounted within the mounting base, and its connecting end extends out of the opening to abut against the abutment portion.
[0009] In one embodiment, the mounting base includes an outer frame and a spring seat, the spring seat being disposed within the outer frame, the outer frame being fixedly connected to the mounting base, and the outer frame having an opening. A drum portion is supported on the spring seat and confined within the outer frame.
[0010] In one embodiment, there are multiple elastic elements, which are spaced apart along a first direction. Multiple spring seats are provided within the outer frame, each corresponding to one of the multiple elastic elements. The lifting seat has multiple abutment portions, each corresponding to one of the multiple elastic elements, and the connecting end can abut against the corresponding abutment portion on the side away from the slot along the first direction.
[0011] In one embodiment, the lifting seat is provided with a first guide groove, which extends along a first direction and is spaced apart from the through groove along a third direction; wherein the third direction is perpendicular to the first direction and the second direction respectively; the electronic device further includes a first guide member, which is connected to a fixed bracket and is movably fitted into the first guide groove along the first direction; and / or, the fixed bracket is provided with a second guide groove, which extends along the first direction and is spaced apart from the through groove along a third direction; wherein the third direction is perpendicular to the first direction and the second direction respectively; the electronic device further includes a second guide member, which is connected to the lifting seat and is movably fitted into the second guide groove along the first direction.
[0012] In one embodiment, the elastic element includes a torsion spring. The elastic element includes a spring body and two spring arms, each connected to the spring body and rotatable relative to it. The spring body is mounted on a lifting seat and moves with it. The side of each spring arm furthest from the spring body extends towards the side closest to the slot. The buffer structure also includes a limiting structure located on the outer side of the fixed bracket furthest from the mounting slot. The limiting structure is supported on the side of the two spring arms furthest from each other, so that the two spring arms are brought closer together.
[0013] In one embodiment, the limiting structure includes two limiting portions located on either side of the through groove along a third direction. Each limiting portion corresponds to one of the two spring arms, and the limiting portion can abut against the side of the corresponding spring arm furthest from the other spring arm, causing the spring arm to move closer to the other spring arm. The third direction is perpendicular to both the first and second directions.
[0014] In one embodiment, the lifting seat is recessed inward along the first direction near the slot opening to form a groove. The protrusion can be engaged in the groove and abut against the bottom surface of the groove.
[0015] In one embodiment, there are multiple through slots, which are arranged opposite to each other and spaced apart along a third direction; wherein the third direction is perpendicular to the first direction and the second direction, respectively. There are multiple protrusions, which are arranged in a one-to-one correspondence with the multiple through slots. There are multiple buffer structures, which are arranged in a one-to-one correspondence with the multiple through slots. Attached Figure Description

[0059] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0060] Example
[0061] Figure 1 This is a schematic diagram of the structure of an electronic device 100 in one embodiment of this application; Figure 2 for Figure 1 Exploded view of electronic device 100 in the illustrated embodiment; Figure 3 for Figure 1 A partial structural diagram of the buffer structure 30 and the fixing bracket 10 in the embodiment shown.
[0062] See Figures 1 to 3 This embodiment provides an electronic device 100, including a fixed bracket 10, electronic components 20, and a buffer structure 30.
[0063] The fixed bracket 10 is provided with a mounting groove 10a, which has an opening 10b that opens along the first direction X. The fixed bracket 10 is provided with a through groove 10c along one side of the fixed bracket along the second direction Y, which communicates with the mounting groove 10a and extends along the first direction X. The second direction Y is perpendicular to the first direction X. An electronic device 20 is mounted in the mounting groove 10a, and the electronic device 20 has a protrusion 21 that can move along the first direction X within the through groove 10c. The buffer structure 30 includes a lifting seat 31 and an elastic member 32. The lifting seat 31 is movably fitted into the through slot 10c along the first direction X, and the lifting seat 31 can abut against the side of the protrusion 21 away from the slot opening 10b along the first direction X during the process of inserting the electronic device 20 into the mounting slot 10a along the first direction X. The elastic member 32 is disposed between the lifting seat 31 and the fixed bracket 10, and is configured to apply an elastic force to the lifting seat 31 along the first direction X toward the side closer to the slot opening 10b.
[0064] In the aforementioned electronic device 100, when the electronic component 20 is inserted into the mounting slot 10a, the protrusion 21 moves along with the electronic component 20 within the through slot 10c, thereby pushing the lifting seat 31 within the through slot 10c to move along the first direction X toward the side away from the slot opening 10b. Since the elastic element 32 is located between the lifting seat 31 and the fixed bracket 10, and can apply an elastic force to the lifting seat 31 in the first direction X toward the side closer to the slot opening 10b, the protrusion 21 experiences resistance toward the side closer to the slot opening 10b. This provides a buffering effect for the electronic component 20 during installation, preventing it from colliding with the bottom of the mounting slot 10a along the first direction X, thereby reducing the risk of damage during installation and improving the production yield of the electronic device 100. When the electronic component 20 is removed from the mounting slot 10a along the first direction X, the elastic force of the elastic element 32 makes the removal of the electronic component 20 easier.
[0065] In use, the first direction X can be the direction of gravity, meaning that when inserting the electronic device 20 into the mounting slot 10a, the electronic device 20 is inserted from top to bottom along the direction of gravity. By setting the buffer structure 30, the electronic device 20 is prevented from falling to the bottom of the mounting slot 10a due to its own weight. Furthermore, because of the buffer structure 30, during the installation process, the user does not need to rely solely on manual force to control the descent speed of the electronic device 20, making the installation process easier and more stable.
[0066] In this embodiment, the electronic device 20 is a power supply unit (PSU) used to supply power to other components of the computer. In use, the mounting bracket 10 can be fixed inside the computer chassis (not shown), and then the electronic device 20 can be installed on the mounting bracket 10, thus completing the assembly of the electronic device 20 with the chassis. In other embodiments, the electronic device 20 can also be other devices that need to be assembled into the chassis.
[0067] Alternatively, the protrusion 21 can be a fastener, such as a T-screw, that is fixedly connected to the electronic device 20.
[0068] Figure 4 for Figure 1 An exploded view of the buffer structure 30 in the illustrated embodiment.
[0069] In some embodiments, combined with Figure 3 and Figure 4 As shown, the elastic element 32 includes a constant-force spring. The elastic element 32 includes a drum portion 321 and a connecting end 322. The drum portion 321 is rotatably mounted on the fixed bracket 10 away from the mounting groove 10a (see...). Figure 2 On the outside of the lifting seat 31, the connecting end 322 is connected to the drum portion 321. The lifting seat 31 has an abutment portion 311 corresponding to the connecting end 322. The connecting end 322 can abut against the abutment portion 311 in the first direction X, away from the slot 10b, to apply an elastic force to the lifting seat 31 in the first direction X towards the slot 10b. Thus, by setting the elastic element 32 as a constant-force spring, the connecting end 322 of the elastic element 32 can move linearly, and the rebound force on the connecting end 322 is more constant. Therefore, when the connecting end 322 abuts against the abutment portion 311, the connecting end 322 can move along the first direction X with the lifting seat 31, providing a more constant elastic force to the lifting seat 31. In use, when the elastic element 32 is not subjected to external force, the connecting end 322 is close to the drum portion 321, and when the elastic element 32 is subjected to the pulling force of the abutting portion 311, the abutting portion 311 pulls the connecting end 322 away from the drum portion 321.
[0070] In some embodiments, such as Figures 2 to 4 As shown, the buffer structure 30 also includes a mounting base 33, which is located on the outer side of the fixed bracket 10 away from the mounting groove 10a. The mounting base 33 is located on the side of the through groove 10c along the third direction Z, and the mounting base 33 has an opening 33a on the side near the through groove 10c. The third direction Z is perpendicular to the first direction X and the second direction Y. The drum portion 321 is installed in the mounting base 33, and the connecting end 322 extends out of the opening 33a to abut against the abutment portion 311. In this way, by providing the mounting base 33, the position of the drum portion 321 is fixed relative to the fixed bracket 10.
[0071] In some embodiments, such as Figure 4 As shown, the mounting base 33 includes an outer frame 331 and a spring seat 332, which are combined with... Figure 3 As shown, the spring seat 332 is disposed within the outer frame 331, which is fixedly connected to the mounting base 33. The outer frame 331 has an opening 33a. The drum portion 321 is supported on the spring seat 332 and is confined within the outer frame 331. Thus, the drum portion 321 is confined on the spring seat 332 by the outer frame 331, and is housed within the outer frame 331, thereby making the electronic device 100 more aesthetically pleasing.
[0072] In some embodiments, such as Figure 4 As shown, there are multiple elastic elements 32, which are spaced apart along the first direction X. Multiple spring seats 332 are provided inside the outer frame 331, each corresponding to one of the multiple elastic elements 32. Multiple abutment portions 311 are provided on the lifting seat 31, each corresponding to one of the multiple elastic elements 32. The connecting end 322 can abut against the corresponding abutment portion 311 along the first direction X, away from the slot 10b (see...). Figure 2 On one side. In this way, the buffer structure 30 can provide greater elastic force, thereby providing a better buffering effect. In this embodiment, two spring seats 332 and two elastic elements 32 are respectively provided inside the outer frame 331, and two abutment parts 311 are provided on the lifting seat 31.
[0073] In some embodiments, such as Figure 3 As shown, the lifting seat 31 is provided with a first guide groove 31a, which extends along a first direction X and is spaced apart from the through groove 10c along a third direction Z. The electronic device 100 also includes a first guide member 40, which is connected to the fixed bracket 10 and is movably engaged with the first guide groove 31a along the first direction X. Thus, the engagement of the first guide member 40 and the first guide groove 31a provides guidance for the movement of the lifting seat 31 along the first direction X.
[0074] In some embodiments, such as Figure 3 As shown, the fixed bracket 10 is provided with a second guide groove 10d, which extends along the first direction X and is spaced apart from the through groove 10c along the third direction Z. The electronic device 100 also includes a second guide member 50, which is connected to the lifting seat 31 and is movably engaged with the second guide groove 10d along the first direction X. Thus, through the engagement of the second guide member 50 and the second guide groove 10d, the movement of the lifting seat 31 along the first direction X is guided.
[0075] In some embodiments, such as Figure 3As shown, the lifting seat 31 is recessed along the first direction X near the slot 10b to form a groove 31b. The protrusion 21 can be inserted into the groove 31b and abut against the bottom surface of the groove 31b. In this way, the groove 31b positions the protrusion 21 relative to the lifting seat 31, making the movement of the lifting seat 31 driven by the protrusion 21 more stable.
[0076] In some embodiments, such as Figure 2 As shown, there are multiple through slots 10c, which are arranged opposite to each other and spaced apart along the third direction Z. There are multiple protrusions 21, which are arranged one-to-one with the multiple through slots 10c. There are multiple buffer structures 30, which are arranged one-to-one with the multiple through slots 10c. In this way, the multiple buffer structures 30 can respectively provide force to the electronic device 100 towards the slot opening 10b, further improving the yield of the electronic device 100 and making the installation and removal of the electronic device 100 easier.
[0077] Figure 5 This is a schematic diagram of the structure of electronic device 100A in another embodiment of this application; Figure 6 for Figure 5 Exploded view of electronic device 100A in the illustrated embodiment; Figure 7 for Figure 5 A partial structural schematic diagram of the buffer structure 30A and the fixing bracket 10 in the embodiment shown; Figure 8 for Figure 5 A partial structural diagram of the buffer structure 30A and the fixing bracket 10 in another usage state in the embodiment shown.
[0078] See Figure 5 and Figure 6 The electronic device 100A in Embodiment 2 is substantially the same as the electronic device 100 in Embodiment 1, except that it is combined with... Figure 7 and Figure 8 As shown, the elastic element 32A includes a torsion spring. The elastic element 32A includes a spring body 323 and two spring arms 324. The two spring arms 324 are respectively connected to the spring body 323 and are rotatable relative to the spring body 323. The spring body 323 is located on the lifting seat 31A and can move with the lifting seat 31A. The side of the two spring arms 324 away from the spring body 323 faces towards the slot 10b (see...). Figure 6 The buffer structure 30 extends to one side. The buffer structure 30 also includes a limiting structure 34, which is located on the fixed bracket 10 away from the mounting groove 10a (see...). Figure 6 On the outside of the spring arms 324, the limiting structure 34 is supported on the side of the two spring arms 324 that are far apart from each other, so that the two spring arms 324 are brought closer together. Thus, the limiting structure 34 supports the two spring arms 324 respectively, as... Figure 7As shown, when the lifting seat 31A is not subjected to external force, the limiting structure 34 is supported on the end of the spring arm 324 near the spring body 323, as follows. Figure 8 As shown, when the protrusion 21 pushes the lifting seat 31A to move away from the slot 10b, the limiting structure 34 moves relative to the spring arm 324 toward the end of the spring arm 324 away from the spring body 323, causing the two spring arms 324 to rotate and close relative to the spring body 323, thereby subjecting the two spring arms 324 to an elastic force in the opening direction, and thus applying resistance to the lifting seat 31A toward the side closer to the slot 10b.
[0079] In some embodiments, such as Figure 7 and Figure 8 As shown, the limiting structure 34 includes two limiting portions 341, which are located on both sides of the through groove 10c along the third direction Z. The two limiting portions 341 correspond to the two spring arms 324 respectively, and the limiting portions 341 can abut against the side of the corresponding spring arm 324 away from the other spring arm 324, so that the spring arm 324 moves closer to the side of the other spring arm 324. In this way, the structure of the limiting structure 34 is simple.
[0080] Figure 9 for Figure 5 A schematic diagram of the buffer structure 30A in the illustrated embodiment.
[0081] In some embodiments, such as Figure 9 As shown, the lifting seat 31A has sliding grooves 31c on both sides along the third direction Z. The sliding grooves 31c pass through the lifting seat 31A along the first direction X. Figure 7 As shown, the portions of the fixed bracket 10 located on both sides of the through groove 10c are slidably inserted into the two sliding grooves 31c. In this way, the lifting seat 31A is confined within the through groove 10c, and the lifting seat 31A can slide relative to the fixed bracket 10 along the first direction X.
[0082] In other embodiments, the elastic element 32 may also be a tension spring or a compression spring, etc.
