[0081] The following combination Figures 1 to 23 Chassis and electronic devices according to embodiments of the present disclosure.

[0082] In embodiments of this disclosure, such as Figures 1 to 4As shown, the chassis includes a housing 10, a first mounting bracket 20, a second mounting bracket 30, a first mounting assembly 40, and a second mounting assembly 50. The first mounting bracket 20 is disposed on the housing 10 and has intersecting first and second directions. The second mounting bracket 30 is disposed on the housing 10 and spaced apart from the first mounting bracket 20 along a third direction. A first region and a second region are formed between the first mounting bracket 20 and the second mounting bracket 30. The first region and the second region are different, and the third direction is perpendicular to the first and second directions. The first mounting assembly 40 is disposed in the first region and extends along the first direction. One end of the first mounting assembly 40 is rotatably connected to the first mounting bracket 20, and the other end is locked to the second mounting bracket 30. The first mounting assembly 40 is used to mount a fan unit 70 of electronic equipment. The second mounting assembly 50 is disposed in the second region and extends along the second direction. One end of the second mounting assembly 50 is movably connected to the first mounting bracket 20, and the other end is movablely connected to the second mounting bracket 30. The second mounting assembly 50 is used to mount a graphics card unit 80 of electronic equipment.

[0083] The chassis includes a housing 10 and a first mounting bracket 20, a second mounting bracket 30, a first mounting assembly 40, and a second mounting assembly 50 mounted on the housing 10. The housing 10 can be generally rectangular or square in shape, and its interior forms a receiving space. The housing 10 has a length direction, a width direction, and a height direction. The length direction is described as the first direction, the width direction as the second direction, and the height direction as the third direction. The first direction, the second direction, and the third direction are as follows: Figure 2 and Figure 4 As shown in the diagram, the enclosure 10 may include an enclosure body 11 and an enclosure door 12. The enclosure body 11 may be formed by multiple side walls. The enclosure body 11 may include a first side wall 111 and a second side wall 112 spaced apart along a first direction, and a third side wall connected to the first side wall 111 and the second side wall 112. The enclosure body 11 has an opening, and the enclosure door 12 is detachably connected to the opening of the enclosure body 11. Removing the enclosure door 12 facilitates the inspection, repair, and replacement of components inside the enclosure 10.

[0084] The first fixing frame 20 and the second fixing frame 30 are spaced apart along a third direction, such as Figure 2 and Figure 4As shown, the first mounting bracket 20 can be installed at one end of the housing 10 in a third-direction direction, and the second mounting bracket 30 can be installed at the other end of the housing 10 in a third-direction direction. The spacing between the first mounting bracket 20 and the second mounting bracket 30 is set according to actual needs. The length direction of the first mounting bracket 20 is consistent with the first direction, and the width direction of the first mounting bracket 20 is consistent with the second direction. The first mounting bracket 20 and the second mounting bracket 30 provide mounting bases for the first mounting component 40 and the second mounting component 50. In addition, the first mounting bracket 20 and the second mounting bracket 30 also provide mounting bases for other components inside the housing 10. The length of the first mounting bracket 20 is adapted to the length of the housing 10, and the width of the first mounting bracket 20 is adapted to the width of the housing 10. The length of the second mounting bracket 30 is adapted to the length of the housing 10, and the width of the second mounting bracket 30 is adapted to the width of the housing 10.

[0085] A first region and a second region are formed between the first fixing frame 20 and the second fixing frame 30. Two opposing portions of the first fixing frame 20 in a second direction are described as a first side and a second side, respectively, and two opposing portions of the first fixing frame 20 in a first direction are described as a first end and a second end, respectively. Two opposing portions of the second fixing frame 30 in a second direction are described as a third side and a fourth side, respectively, and two opposing portions of the second fixing frame 30 in a first direction are described as a third end and a fourth end, respectively. The first region may be the region covering the area between the first side of the first fixing frame 20 and the third side of the second fixing frame 30. The second region may be the region covered by extending from the central region of the first fixing frame 20 toward the central region of the second fixing frame 30.

[0086] like Figure 2 and Figure 3 As shown, the first mounting assembly 40 is used to mount the fan unit 70, and the first mounting assembly 40 is mounted in the first region. The first mounting assembly 40 may include a bracket 41, one end of which is rotatably connected to the first fixing frame 20, and the other end of which is locked to the second fixing frame 30. One, two, or more fan units 70 can be mounted on the bracket 41.

[0087] The process of installing the first mounting component 40 is as follows: place one end of the bracket 41 at the mounting position of the first fixing bracket 20, such as... Figure 5 As shown, at this time, the bracket 41 is tilted relative to the housing 10; rotate the bracket 41 from the tilted position to a position approximately parallel to the housing 10, as shown... Figure 2 As shown, the bracket 41 is in a vertical position. After the bracket 41 is rotated into place, the other end of the bracket 41 is locked with the second fixing frame 30, thereby fixing the first mounting component 40 on the first fixing frame 20 and the second fixing frame 30.

[0088] The process of disassembling the first mounting component 40 is as follows: the other end of the bracket 41 can be unlocked from the second fixing frame 30 by pressing. Then, the bracket 41 is rotated from a vertical position to an inclined position. After the bracket 41 is rotated into place, one end of the bracket 41 can be separated from the first fixing frame 20.

[0089] The first mounting component 40 can be fixed to the first fixing frame 20 and the second fixing frame 30 by applying a rotation or pressing action, or the first mounting component 40 can be removed from the first fixing frame 20 and the second fixing frame 30, which facilitates the installation and removal.

[0090] like Figure 4 As shown, the second mounting component 50 is used to mount the graphics card unit 80, and the second mounting component 50 is mounted in the second region. The graphics card unit 80 can be flat. When the graphics card unit 80 is placed in the second region, the thickness direction of the graphics card unit 80 can be consistent with the first direction, the width direction of the graphics card unit 80 can be consistent with the second direction, and the length direction of the graphics card unit 80 can be consistent with the third direction. The second mounting component 50 can include two connectors, which are described as a first connector 51 and a second connector 52, respectively. The first connector 51 is movably connected to the first mounting bracket 20, and the second connector 52 is movably connected to the second mounting bracket 30. The two ends of the graphics card unit 80 in the third direction are described as the first end of the graphics card unit 80 and the second end of the graphics card unit 80, respectively. The first end of the graphics card unit 80 is located on the first mounting bracket 20, and the second end of the graphics card unit 80 is away from the first mounting bracket 20. The first connector 51 can be rotatably connected to the first mounting bracket 20, and the first connector 51 can abut against the first end of the graphics card unit 80.

[0091] The process of installing the graphics card unit 80 is as follows: connect the second connector 52 to the second end of the graphics card unit 80, place the graphics card unit 80 and the second connector 52 in the second area inside the housing 10, and then connect the second connector 52 to the second mounting bracket 30 with fasteners; then apply a rotation action to the first connector 51, so that the first connector 51 rotates to abut against the first end of the graphics card unit 80, thereby fixing the graphics card unit 80 on the first mounting bracket 20 and the second mounting bracket 30.

[0092] The process of disassembling the graphics card unit 80 is as follows: remove the fasteners connecting the second connector 52 to the second mounting bracket 30, rotate the first connector 51 to separate the first connector 51 from the graphics card unit 80, remove the graphics card unit 80 and the second connector 52 from the housing 10, and then remove the fasteners connecting the second connector 52 to the graphics card unit 80, thereby completing the disassembly of the graphics card unit 80.

[0093] The second connector 52 is movably connected to the second mounting bracket 30 in the third direction. The installation position of the second connector 52 and the second mounting bracket 30 can be flexibly adjusted according to the length of the graphics card unit 80 to accommodate graphics card units 80 of different lengths.

[0094] The first connector 51 abuts against or separates from the first end of the graphics card unit 80 under the action of external force. The second connector 52 is connected to the second end of the graphics card unit 80 and is movably connected to the second fixing bracket 30. This facilitates the installation and removal of the graphics card unit 80 and can also be adapted to install graphics card units 80 of different specifications and sizes.

[0095] In the embodiments of this disclosure, the first mounting bracket 20 and the second mounting bracket 30 are vertically spaced within the housing 10. The first mounting assembly 40 is used to mount the fan unit 70. One end of the first mounting assembly 40 is rotatably connected to the first mounting bracket 20, and the other end is locked to the second mounting bracket 30. The first mounting assembly 40 can be installed or removed by applying rotation or pressing actions, which facilitates installation and removal. The second mounting assembly 50 is used to mount the graphics card unit 80. One end of the second mounting assembly 50 can abut or separate from the graphics card unit 80 under external force, and the other end of the second mounting assembly 50 is movably connected to the second mounting bracket 30. This facilitates the installation and removal of the graphics card unit 80 and allows for the installation of graphics card units 80 of different models and sizes.

[0096] In embodiments of this disclosure, such as Figure 6 As shown, the first fixing frame 20 is provided with a limiting member 21, such as Figure 8 As shown, the second fixing bracket 30 is provided with a first locking part 33. (As indicated...) Figure 11 As shown, the first mounting assembly 40 includes a bracket 41, a limiting structure 42, and a locking structure 43. The bracket 41 has at least one opening, and the fan unit 70 is located at the opening. The limiting structure 42 is located at one end of the bracket 41 and is rotatably connected to the limiting member 21. The locking structure 43 is located at the other end of the bracket 41 and includes a second locking part 432, which can switch between a locked state and an unlocked state with respect to the limiting member 21. When the limiting structure 42 is rotated relative to the limiting member 21 to a first position, and the first locking part 33 and the second locking part 432 are in the locked state, the first mounting assembly 40 is fixed to the first fixing frame 20 and the second fixing frame 30. When the first locking part 33 and the second locking part 432 are in the unlocked state, and the limiting structure 42 is rotated relative to the limiting member 21 to a second position, the limiting structure 42 and the limiting member 21 are separable, and the second position is different from the first position.

[0097] Along the length of the bracket 41, the two ends of the bracket 41 are respectively described as the first end of the bracket 41 and the second end of the bracket 41. The first end of the bracket 41 is connected to the first fixing frame 20, and the second end of the bracket 41 is connected to the second fixing frame 30. The limiting structure 42 can be located at the first end of the bracket 41, and the locking structure 43 can be located at the second end of the bracket 41.

[0098] In some embodiments, such as Figure 11 and Figure 12 As shown, the bracket 41 includes a bracket body 411 and a side plate 412 connected to the bracket body 411. The side plate 412 can be perpendicular to the bracket body 411. A limiting structure 42 is located at the first end of the side plate 412, and a locking structure 43 is located at the second end of the bracket body 411. The bracket body 411 has an opening that can accommodate one, two, or more fan units 70. The fan units 70 can be connected to the bracket body 411 or the side plate 412 by means of snap-fit, screw connection, or other methods.

[0099] The first fixed frame 20 is provided with a limiting member 21, and a limiting structure 42 is rotatably connected to the limiting member 21. When a flipping force is applied to the bracket 41, the limiting structure 42 can rotate relative to the limiting member 21 to a first posture or a second posture. In the first posture, the limiting structure 42 and the limiting member 21 are inseparable; in the second posture, the limiting structure 42 can be separated from the limiting member 21.

[0100] In some embodiments, such as Figure 9 and Figure 10 As shown, the limiting member 21 is provided with a limiting groove 2121, such as Figure 11 and Figure 12 As shown, the limiting structure 42 includes a first protrusion 421 and a second protrusion 422 protruding from the side plate 412. The first protrusion 421 and the second protrusion 422 can be columnar. The first protrusion 421 can rotate in the limiting groove 2121, and the second protrusion 422 is located outside the limiting groove 2121. When the first end of the bracket 41 is placed at the first fixing frame 20, the first protrusion 421 is located in the limiting groove 2121. A flipping force is applied to the bracket 41 toward the side facing the second fixing frame 30. As the first protrusion 421 rotates in the limiting groove 2121, the second protrusion 422 rotates relative to the central axis of the first protrusion 421. The bracket 41 is rotated to a vertical position, and the limiting structure 42 is rotated to a first position relative to the limiting member 21. The first protrusion 421 abuts against the bottom surface of the limiting groove 2121, and the second protrusion 422 can abut against or fit against the inner surface of the limiting member 21. The second protrusion 422 is opposite to the inner surface of the limiting member 21, and the limiting structure 42 and the limiting member 21 are inseparable.

[0101] A flipping force is applied to the bracket 41 toward the side opposite to the second fixing frame 30. As the first protrusion 421 rotates in the limiting groove 2121, the second protrusion 422 rotates relative to the central axis of the first protrusion 421. The bracket 41 rotates to an inclined position, and the limiting structure 42 rotates relative to the limiting member 21 to a second position. The second protrusion 422 is located on the top side of the limiting member 21, and the second protrusion 422 can face the top surface of the limiting member 21. The first protrusion 421 can be removed from the limiting groove 2121, and the limiting structure 42 can be separated from the limiting member 21.

[0102] like Figure 8 As shown, the second fixing bracket 30 is provided with a first locking part 33, and the locking structure 43 is locked to the first locking part 33. The locking structure 43 and the first locking part 33 can be locked or unlocked by pressing. Figure 11 As shown, the locking structure 43 includes a second locking part 432, which may be provided with a slot 4321. The first locking part 33 may be a locking tongue that is adapted to the slot 4321. The locking structure 43 may also include an elastic member 434.

[0103] Rotate the second end of the bracket 41 to the second fixed frame 30. Under the mutual compression of the first locking part 33 and the second locking part 432 and the rebound force of the elastic member 434, the first locking part 33 is inserted into the slot 4321 of the second locking part 432, thereby locking the first locking part 33 and the second locking part 432 and connecting the second end of the bracket 41 to the second fixed frame 30.

[0104] Pressing the locking structure 43 causes the second locking part 432 to move away from the first locking part 33 until the first locking part 33 is completely removed from the slot 4321 of the second locking part 432, thereby unlocking the first locking part 33 from the second locking part 432.

[0105] The following describes the installation and removal process of the first mounting component 40.

[0106] The installation process is as follows: the bracket 41 is placed at an angle on the first fixed frame 20, and the limiting structure 42 is located in the limiting groove 2121 of the limiting member 21. A flipping force is applied to the bracket 41 toward the side facing the second fixed frame 30, and the limiting structure 42 rotates in the limiting groove 2121. The bracket 41 rotates from the angled position to the vertical position, and the limiting structure 42 switches from the second position to the first position relative to the limiting member 21. At this time, the limiting structure 42 and the limiting member 21 are inseparable. At the same time, the first locking part 33 is inserted into the slot 4321 of the second locking part 432, and the first locking part 33 and the second locking part 432 are locked, thereby realizing the connection between the first end of the bracket 41 and the first fixed frame 20 and the second end of the bracket 41 and the second fixed frame 30.

[0107] The disassembly process is as follows: Press the locking structure 43, the second locking part 432 unlocks from the first locking part 33, apply a flipping force to the bracket 41 toward the side away from the second fixed frame 30, the limiting structure 42 rotates in the limiting groove 2121, the bracket 41 rotates from the vertical posture to the tilted posture, the limiting structure 42 switches from the first posture to the second posture relative to the limiting member 21, at this time the limiting structure 42 and the limiting member 21 can be separated, the bracket 41 is removed from the first fixed frame 20, thereby realizing the disassembly of the bracket 41.

[0108] In the embodiments disclosed herein, during installation, a flipping force is applied to the bracket 41, causing it to rotate from an inclined position to a vertical position. The limiting structure 42 switches from a second position to a first position, and the second locking part 432 locks with the first locking part 33, thereby connecting the bracket 41 to the first fixing frame 20 and the second fixing frame 30. During disassembly, pressing the locking structure 43 unlocks the second locking part 43 from the first locking part 33. Then, a flipping force is applied to the bracket 41, causing it to rotate to an inclined position. The limiting structure 42 switches from the first position to the second position, thus enabling the bracket 41 to be disassembled. Installation and disassembly are convenient.

[0109] In embodiments of this disclosure, such as Figure 9 and Figure 10 As shown, the limiting member 21 includes a connecting part 211 and a limiting part 212. The connecting part 211 is connected to the first fixing frame 20, and the limiting part 212 is provided with a limiting groove 2121. Figure 11 and Figure 12 As shown, the limiting structure 42 includes a first protrusion 421 and a second protrusion 422 that are offset from each other. In a first posture, the first protrusion 421 abuts against the groove wall of the limiting groove 2121, and the second protrusion 422 is located outside the limiting groove 2121 and opposite to the first surface 2122 of the limiting part 212, thereby restricting the movement of the bracket 41. In a second posture, the second protrusion 422 is located outside the limiting groove 2121 and opposite to the second surface 2123 of the limiting part 212. The limiting structure 42 and the limiting member 21 are separable, and the second surface 2123 intersects with the first surface 2122.

[0110] The limiting member 21 can be fixed to the side of the first fixing frame 20 facing the second fixing frame 30, that is, the limiting member 21 can be fixed to the top surface of the first fixing frame 20. The number of limiting members 21 can be one, two, or more. When there are two limiting members 21, the two limiting members 21 are spaced apart along the first direction. When there are multiple limiting members 21, the multiple limiting members 21 are spaced apart along the first direction.

[0111] The limiting member 21 includes a connecting part 211 and a limiting part 212. The connecting part 211 can be fixed to the first fixing frame 20 by fasteners. For example, the first fixing frame 20 is provided with a threaded hole, and the connecting part 211 is provided with a through hole. The through hole and the threaded hole are compatible. The fasteners can include screws. The screws are screwed into the through hole and the threaded hole to realize the connection between the connecting part 211 and the first fixing frame 20.

[0112] The limiting part 212 can be a block-shaped body, with a limiting groove 2121 formed by a recess in one surface of the limiting part 212. This surface is described as the outer surface, the inner surface opposite to the outer surface is described as the first surface 2122, and the surface connected to the first surface 2122 and facing away from the first fixing frame 20 is described as the second surface 2123. The second surface 2123 is opposite to the second fixing frame 30. The limiting groove 2121 can be an approximately U-shaped limiting groove.

[0113] In some embodiments, the bracket 41 includes a bracket body 411 and two side plates 412 disposed on both sides of the bracket body 411. Each side plate 412 may be provided with a limiting structure 42, which is located at the first end of the side plate 412. The limiting structure 42 includes a first protrusion 421 and a second protrusion 422, which protrude from the side plate 412. The first protrusion 421 and the second protrusion 422 can be columnar, which can be solid or hollow. The first protrusion 421 and the second protrusion 422 are staggered. For example, the first protrusion 421 and the second protrusion 422 are spaced apart in the length direction of the side plate 412 and in the width direction of the side plate 412.

[0114] In some embodiments, two limiting members 21 are spaced apart on the first fixing frame 20 along a first direction, and the distance between the two limiting members 21 is adapted to the width of the bracket 41. The two limiting members 21 correspond one-to-one with the two limiting structures 42.

[0115] The first end of the bracket 41 is placed on the first fixed frame 20. The first protrusions 421 of the two limiting structures 42 are respectively located in the limiting grooves 2121 of the two limiting members 21, and the second protrusions 422 are approximately opposite to the second surface 2123 of the limiting part 212. A flipping force is applied to the bracket 41 toward the side facing the second fixed frame 30. As the first protrusions 421 rotate in the limiting grooves 2121, the second protrusions 422 rotate relative to the central axis of the first protrusions 421. The bracket 41 rotates to a vertical position, and the limiting structures 42 rotate relative to the limiting members 21 to a first position. At this time, the first protrusions 421 abut against the groove wall of the limiting groove 2121, and the second protrusions 422 are approximately opposite to the first surface 2122 of the limiting part 212. The second protrusions 422 can abut against the first surface 2122. Figure 6 and Figure 7 As shown, two first protrusions 421 are respectively located in the limiting grooves 2121 of the two limiting members 21. The end faces of the two first protrusions 421 abut against the groove walls of the two limiting grooves 2121, which can restrict the movement of the first end of the bracket 41 along the first direction. The circumferential surfaces of the two first protrusions 421 abut against the groove walls of the two limiting grooves 2121, which can restrict the movement of the bracket 41 toward the inside of the housing 10. The two second protrusions 422 abut against the first surfaces 2122 of the two limiting members 21, which can restrict the movement of the bracket 41 toward the outside of the housing 10, thereby restricting the movement of the first end of the bracket 41 along the second direction. The two opposite side groove walls of the limiting grooves 2121 can restrict the movement of the bracket 41 along a third direction. Thus, the movement of the first end of the bracket 41 along the first direction, the second direction, and the third direction can be restricted.

[0116] After the second locking part 432 unlocks from the first locking part 33, a flipping force is applied to the bracket 41 toward the side opposite to the second fixing frame 30. As the first protrusion 421 rotates in the limiting groove 2121, the second protrusion 422 rotates relative to the central axis of the first protrusion 421. The bracket 41 rotates to an inclined position, and the limiting structure 42 rotates relative to the limiting member 21 to a second position. At this time, the second protrusion 422 and the second surface 2123 of the limiting part 212 are approximately opposite each other, and the first protrusion 421 and the second protrusion 422 can be separated from the limiting member 21, thereby allowing the bracket 41 to be removed from the housing 10.

[0117] The first protrusion 421 and the second protrusion 422 are offset at the side plate 412 of the bracket 41. The first protrusion 421 is rotatably connected to the limiting groove 2121 of the limiting member 21. As the bracket 41 rotates, such as Figure 7As shown, the second protrusion 422 rotates to face the first surface 2122 of the limiting member 21, thereby fixing the limiting structure 42 and the limiting member 21 relative to each other; the second protrusion 422 rotates to face the second surface 2123 of the limiting member 21, thereby separating the limiting structure 42 and the limiting member 21.

[0118] In some embodiments, such as Figure 2 As shown, there can be two first mounting components 40, which are arranged sequentially along the first direction. There can be three limiting members 21, which are spaced apart along the first direction, and two adjacent limiting members 21 are used to connect with the first end of the bracket 41.

[0119] like Figure 10 As shown, the limiting member 21 can be provided with two limiting grooves 2121, which are arranged opposite to each other. One limiting groove 2121 of the middle limiting member 21 can be connected to the first protrusion 421 of a bracket 41, and the other limiting groove 2121 can be connected to the first protrusion 421 of another bracket 41. Thus, the limiting member 21 can be connected to the limiting structure 42 of two adjacent brackets 41, which helps to save the number of parts and the space occupied. Each bracket 41 can install two fan units 70, and two brackets 41 can install four fan units 70, which helps to improve the heat dissipation performance of the chassis. Multiple limiting members 21 are spaced apart along the first direction on the first fixing frame 20, and the number of the first mounting components 40 and the number of fan units 70 can be flexibly configured according to actual needs.

[0120] In the embodiments of this disclosure, the limiting structure 42 includes a first protrusion 421 and a second protrusion 422 that are offset from each other. The first protrusion 421 is rotatably disposed in the limiting groove 2121, and the second protrusion 422 can rotate with the first protrusion 421 to be opposite to the first surface 2122 or the second surface 2123 of the limiting part 212. The limiting structure 42 and the limiting member 21 are fixed or separable through the rotation action. The structure is simple, occupies little space, and is easy to operate.

[0121] In embodiments of this disclosure, such as Figure 11 , Figure 13 and Figure 14As shown, the locking structure 43 includes a base 431, which is mounted on a bracket 41 and has a receiving groove 4311. A second locking part 432 is movably connected to the base 431. A force-applying part 433 is provided on one side of the second locking part 432, passing through the receiving groove 4311. The second locking part 432 has a slot 4321, allowing it to move between a first position and a second position. When the second locking part 432 is in the first position, the first locking part 33 is inserted into the slot 4321, and the first locking part 33 and the second locking part 432 are locked. When the second locking part 432 is in the second position, the first locking part 33 is outside the slot 4321, and the first locking part 33 and the second locking part 432 are released from locking. The bracket 41 can rotate to allow the limiting structure 42 to switch from the first posture to the second posture.

[0122] In some embodiments, the locking structure 43 includes a base 431, a second locking portion 432, an elastic member 434, and a force-applying portion 433. For example... Figure 11 and Figure 12 As shown, the bracket body 411 has an opening at one end away from the first fixing frame 20, and the base 431 is installed on the bracket body 411 at a position corresponding to the opening. The second locking part 432 is movably provided on the base 431. A guide post can be provided on the base 431, and a guide groove can be provided on the second locking part 432. The guide post passes through the guide groove, and the length direction of the guide groove is consistent with the third direction. The second locking part 432 can move between the first position and the second position along the third direction.

[0123] The second locking part 432 is provided with a slot 4321, into which the first locking part 33 can be inserted. A force-applying part 433 is provided on one side of the second locking part 432, facilitating the application of external force to the second locking part 432. The base 431 is provided with a receiving groove 4311, which can be an approximately square-shaped through groove. The force-applying part 433 can pass through the receiving groove 4311 of the base 431 and protrude through the opening of the bracket body 411.

[0124] A stop plate may be provided at the bottom of the base 431. The elastic element 434 may include a spring, one end of which may be connected to the bottom surface of the second locking part 432, and the other end of which may abut against the stop plate. When the force-applying part 433 is pressed down at the opening, the second locking part 432 may move from the first position to the second position in a third direction; when the external force is removed, the second locking part 432 may return to the first position from the second position under the elasticity of the elastic element 434.

[0125] The locking structure 43 may also include a protective cover 435, which can be placed on the second locking part 432. The protective cover 435 can be connected to the base 431, and enclose most of the locking structure 43 within the cover of the protective cover 435 to provide protection.

[0126] In some embodiments, such as Figure 8 As shown, the first locking part 33 may include two columnar bodies 331, the diameter of which is adapted to the groove width of the slot 4321. When the bracket 41 is pressed towards the inside of the housing 10, the end of the second locking part 432 and the two columnar bodies 331 are pressed against each other, causing the second locking part 432 to move from the first position to the second position along the third direction. At this time, the two columnar bodies 331 are aligned with the slot 4321. Under the action of the elastic force of the elastic member 434, the second locking part 432 returns to the first position along the third direction, and the two columnar bodies 331 are inserted into the slot 4321 of the second locking part 432, thereby locking the first locking part 33 and the second locking part 432.

[0127] During the installation of bracket 41, the second end of bracket 41 is rotated to be close to the second fixed frame 30, and pressure is continued to be applied to bracket 41. Under the squeezing force applied by the first locking part 33, the second locking part 432 moves toward the first fixed frame 20 until the second locking part 432 moves to the second position in the third direction. At this time, the slot 4321 of the first locking part 33 and the second locking part 432 are aligned. When the force-applying part 433 is released, under the action of the elastic force of the elastic member 434, the second locking part 432 returns from the second position to the first position. In the first position, the first locking part 33 is inserted into the slot 4321 of the second locking part 432, thereby realizing the locking of the first locking part 33 and the second locking part 432.

[0128] During the disassembly of bracket 41, the force application part 433 is pressed down, and the second locking part 432 moves from the first position to the second position along the third direction. At this time, the first locking part 33 is located outside the slot 4321 of the second locking part 432. The first locking part 33 and the second locking part 432 are unlocked, and a flipping force is applied to the bracket 41 toward the side away from the second fixing frame 30. As the bracket 41 rotates, the limiting structure 42 switches from the first posture to the second posture. The limiting structure 42 and the limiting member 21 can be separated, thereby the bracket 41 can be removed from the housing 10.

[0129] In the embodiments disclosed herein, during the installation of the bracket 41, the first locking part 33 and the second locking part 432 can be locked by the mutual compression between the first locking part 33 and the second locking part 432 and the rebound force of the elastic member 434; during the disassembly of the bracket 41, the second locking part 432 and the first locking part 33 can be unlocked by pressing the force application part 433. The structure is simple and the operation is convenient.

[0130] The following is a detailed description of the installation and removal process of the first mounting component 40.

[0131] The installation process is as follows: The first end of the bracket 41 is placed on the first fixed frame 20. The first protrusions 421 of the two limiting structures 42 are respectively located in the limiting grooves 2121 of the two limiting members 21. A flipping force is applied to the bracket 41 towards the inside of the housing 10, causing the bracket 41 to rotate from an inclined posture to a near-vertical posture. At the first end of the bracket 41, the limiting structure 42 rotates relative to the limiting member 21 to the first posture, and the second protrusion 422 rotates to face the first surface 2122 of the limiting member 21. The limiting structure 42 is relatively fixed at the limiting member 21, thus connecting the first end of the bracket 41 to the first fixed frame 20. At the second end of the bracket 41, the first locking part 33 and the second locking part 432 press against each other. The second locking part 432 moves along a third direction to the second position. During the process of returning to the first position under the rebound force of the elastic member 434, the second locking part 432 and the first locking part 33 are locked, thus connecting the second end of the bracket 41 to the second fixed frame 30.

[0132] The disassembly process is as follows: Press down on the force-applying part 433, and the second locking part 432 moves downward along the third direction to the second position, unlocking the second locking part 432 from the first locking part 33. Then, apply an outward flipping force to the bracket 41, and the bracket 41 rotates from a vertical position to an inclined position. The limiting structure 42 rotates relative to the limiting member 21 to the second position, and the second protrusion 422 rotates to face the second surface 2123 of the limiting member 21. The limiting structure 42 and the limiting member 21 can be separated, thereby allowing the first mounting assembly 40 to be removed from the first fixing bracket 20 and the second fixing bracket 30.

[0133] In embodiments of this disclosure, such as Figure 4 and Figure 15 As shown, the second mounting assembly 50 includes a first connector 51 and a second connector 52. The first connector 51 is movably mounted on the first mounting bracket 20 and abuts against a first end of the graphics card unit 80. The second connector 52 is connected to a second end of the graphics card unit 80 and is detachably connected to the second mounting bracket 30. The graphics card unit 80 is detachably mounted in the second region via the first connector 51 and the second connector 52.

[0134] The two ends of the graphics card unit 80 in the third direction are described as the first end and the second end of the graphics card unit 80, respectively. The first connector 51 is located at the position corresponding to the first end of the graphics card unit 80, and the second connector 52 is located at the position corresponding to the second end of the graphics card unit 80.

[0135] like Figure 15 and Figure 16 As shown, the first connector 51 can be installed on the first side of the first fixing frame 20, and the first connector 51 is movably connected to the first fixing frame 20. The first connector 51 can be pushed and pulled to abut against the graphics card unit 80; the first connector 51 can be rotated to abut against the first end of the graphics card unit 80; and the first connector 51 can also be pushed, pulled, and rotated to abut against the graphics card unit 80.

[0136] In some embodiments, a first portion of the first connector 51 is movably connected to the first fixing frame 20, and a second portion of the first connector 51 is rotatably connected to the first fixing frame 20. The first and second portions can abut against each other. Pulling the first portion outward toward the outer side of the housing 10 disconnects the second portion from the first portion, the force acting on the second portion disappears, and the second portion can rotate to separate from the graphics card unit 80. Applying a flipping force toward the inner side of the housing 10 to the second portion causes it to rotate to fit against the graphics card unit 80, allowing the first portion to abut against the second portion, thereby achieving contact between the second portion and the graphics card unit 80.

[0137] like Figure 15 As shown, the second connector 52 may include a connecting plate, a first fastener, and a second fastener. The connecting plate may include a first plate body 521 and a second plate body 522 connected to each other. The first plate body 521 is connected to the second end of the graphics card unit 80 via the first fastener, which may include screws. The second plate body 522 is connected to the second mounting bracket 30 via the second fastener, which may also include screws.

[0138] The first plate 521 can be connected to the top surface of the graphics card unit 80, and the first plate 521 can also be connected to the side of the graphics card unit 80. One end of the first plate 521 can be bent and extended to form the second plate 522. The second fixing bracket 30 can be provided with multiple connection holes along the third direction, and the second plate 522 can be connected to any one of the multiple connection holes.

[0139] The following describes the installation and removal process of graphics card unit 80.

[0140] The installation process is as follows: connect the second connector 52 to the second end of the graphics card unit 80, place the graphics card unit 80 and the second connector 52 inside the housing 10, and fit the first end of the graphics card unit 80 against the first mounting bracket 20. Then connect the second connector 52 to the second mounting bracket 30. Then apply external force to the first connector 51, and the second part of the first connector 51 rotates to abut against the first end of the graphics card unit 80, thereby fixing the graphics card unit 80 to the first mounting bracket 20 and the second mounting bracket 30.

[0141] The disassembly process is as follows: first, remove the second fastener on the second connector 52 and the second fixing bracket 30; then, apply external force to the first connector 51, and the second part of the first connector 51 rotates to separate from the first end of the graphics card unit 80. This allows the second connector 52 and the graphics card unit 80 to be removed from the housing 10. Then, remove the first fastener connecting the second connector 52 and the graphics card unit 80, thereby achieving the disassembly of the graphics card unit 80.

[0142] During installation, after the second connector 52 is connected to the second mounting bracket 30, an external force is applied to the first connector 51, causing the first connector 51 to abut against the graphics card unit 80, thus fixing the graphics card unit 80 within the housing 10. During disassembly, the fasteners connecting the second connector 52 to the second mounting bracket 30 are removed, and an external force is applied to the first connector 51, separating it from the graphics card unit 80. The graphics card unit 80 and the first connector 51 can then be removed, thus disassembling the graphics card unit 80.

[0143] In the embodiments of this disclosure, the first connector 51 can be engaged with or disengaged from the graphics card unit 80 under the action of external force, making installation and disassembly convenient; the second connector 52 is movable along a third direction, which can be adapted to install graphics card units 80 of different specifications, which is beneficial to improving versatility.

[0144] In embodiments of this disclosure, such as Figure 16 As shown, the first connecting member 51 includes a movable member 511 and a rotating member 512. The movable member 511 is movably connected to the first fixed frame 20 along a second direction. The rotating member 512 is rotatably connected to the first fixed frame 20, and the rotating member 512 has a third posture and a fourth posture, the third posture being different from the fourth posture. When the movable member 511 moves away from the graphics card unit 80 under the pushing force applied by the rotating member 512, a restoring force is generated on the movable member 511, and the movable member 511 moves towards the graphics card unit 80 under the action of the restoring force; as shown. Figure 16As shown, the rotating component 512 rotates to the third position, and the moving component 511 abuts against the rotating component 512, so that the rotating component 512 abuts against the graphics card unit 80. Under the action of an external force, the moving component 511 moves in a direction away from the graphics card unit 80, and the force exerted by the moving component 511 on the rotating component 512 is released, allowing the rotating component 512 to rotate; as Figure 17 As shown, the rotating component 512 rotates to the fourth posture and separates from the graphics card unit 80.

[0145] like Figure 16 and Figure 19 As shown, a mounting base 22 can be recessed downwards on the first fixing frame 20, and the first connecting member 51 can be installed at the mounting base 22 to avoid affecting the installation of the first mounting assembly 40. The first connecting member 51 includes a moving member 511 and a rotating member 512, which can abut against each other. The moving member 511 can move outwards along the second direction toward the outer side of the housing 10, and can also move inwards along the second direction toward the inner side of the housing 10. The moving member 511 can be movably connected to the first fixing frame 20 via a reset member 5111. The rotating member 512 can be rotatably connected to the first fixing frame 20 via a torsion spring 5125. Without external force, the rotating member 512 can rotate to a fourth position, at which point the rotating member 512 is separated from the graphics card unit 80. A flipping force is applied to the rotating component 512, which can rotate to the third posture. The moving component 511 moves to the contact position and applies a top force toward the graphics card unit 80 to the rotating component 512, thereby achieving contact between the rotating component 512 and the graphics card unit 80.

[0146] In some embodiments, such as Figure 20 As shown, the reset member 5111 may include a tension spring, one end of which is connected to the movable member 511, and the other end of which is connected to the first fixing frame 20. In its natural state, the movable member 511 can abut against the rotating member 512; this position of the movable member 511 is described as its initial position. Pulling the movable member 511 outward along the second direction toward the outside of the housing 10 moves it to a separated position from the rotating member 512. When the external force acting on the movable member 511 disappears, the movable member 511 can be reset to its initial position on the first fixing frame 20 under the reset force provided by the tension spring.

[0147] In some embodiments, such as Figure 21 and Figure 22As shown, the rotating member 512 includes an abutment portion 5121, a guide portion 5122 disposed on one side of the abutment portion 5121, and an actuating portion 5123 connected to the guide portion 5122. Rotating portions 5124 are provided at both ends of the abutment portion 5121, and the rotating portions 5124 are rotatably disposed in the shaft holes of the mounting base 22. At least one rotating portion 5124 is provided with a torsion spring 5125. The first fixed frame 20 is provided with a through groove. The guide portion 5122 may be arc-shaped and passes through the through groove. The actuating portion 5123 is located outside the first fixed frame 20. The moving member 511 has a locking portion at one end facing the rotating member 512, and the guide portion 5122 has a locking groove at the end away from the abutment portion 5121. A flipping force is applied to the actuating part 5123 toward the interior of the housing 10. As the guiding part 5122 rotates with the abutting part 5121, a pushing force along the second direction is applied to the moving part 511, causing the moving part 511 to move toward the outside of the housing 10 along the second direction. The abutting part 5121 rotates until it is in contact with the graphics card unit 80. Under the restoring force of the tension spring, the moving part 511 engages with the slot, and the engaging part abuts against the slot wall. This achieves contact between the abutting part 5121 and the graphics card unit 80. Figure 16 As shown, the rotating component 512 is in the third posture at this time.

[0148] Pulling the movable member 511 towards the outside of the housing 10, the contact force between the movable member 511 and the rotating member 512 disappears, the torque on the torsion spring 5125 disappears, and with the rotation of the rotating part 5124, most of the guide part 5122 rotates to the outside of the first fixing bracket 20, and the contact part 5121 separates from the graphics card unit 80, as... Figure 17 and Figure 18 As shown, the rotating component 512 is in the fourth posture at this time.

[0149] Pull the movable part 511 outward toward the outer side of the housing 10 in the second direction, and rotate the rotating part 512 to the fourth posture, so as to separate the abutting part 5121 from the graphics card unit 80; apply a flipping force to the actuating part 5123 at the bottom of the first fixing bracket 20, and apply a pushing force to the movable part 511 through the guide part 5122 during the rotation process. Rotate the rotating part 512 to the third posture, and the snap-fit ​​part of the movable part 511 abuts against the slot of the guide part 5122, so as to achieve the abutting part 5121 and the graphics card unit 80.

[0150] In some embodiments, the number of guide portions 5122 can be two or more. For example, the number of guide portions 5122 is four, and the four guide portions 5122 are spaced apart on one side of the abutment portion 5121. When the rotating member 512 rotates to the third posture, the four locking portions on the moving member 511 respectively lock into the slots of the four guide portions 5122, which helps to further improve the stability of the rotating member 512 in the third posture and helps the abutment portion 5121 to abut against the graphics card unit 80 stably.

[0151] In the embodiments disclosed herein, the moving member 511 is pulled along the second direction away from the graphics card unit 80, and the rotating member 512 rotates from the third posture to the fourth posture, separating the abutting part 5121 from the graphics card unit 80; a flipping force is applied to the actuating part 5123 toward the inside of the housing 10, and a pushing force is applied to the moving member 511 during the rotation of the rotating member 512, rotating the rotating member 512 from the fourth posture to the third posture, and the moving member 511 moves to abut against the guide part 5122 under the action of the reset force. At this time, the locking part is locked into the slot, realizing the abutting part 5121 abutting against the graphics card unit 80, which is beneficial to the convenience of operation; in addition, the overall structure is compact and occupies little space.

[0152] In embodiments of this disclosure, such as Figure 15 As shown, the second mounting bracket 30 includes a first fixing part 31 and a second fixing part 32. The other end of the first mounting assembly 40 is connected to the first fixing part 31. The second fixing part 32 is disposed on one side of the first fixing part 31 and extends toward the first mounting bracket 20. The second fixing part 32 has multiple connection positions. The second connector 52 is connected to any one of the multiple connection positions.

[0153] In some embodiments, the second fixing frame 30 includes a first fixing part 31 and a second fixing part 32. The length of the first fixing part 31 is adapted to the length of the housing 10, and the width of the first fixing part 31 is adapted to the width of the housing 10. The second fixing part 32 is disposed on the side of the first fixing part 31 facing the first fixing frame 20. The second fixing part 32 can be perpendicular to the first fixing part 31, and the dimension of the second fixing part 32 in the third direction is set according to actual needs.

[0154] The second connector 52 includes a connecting plate, which may include a first plate 521 and a second plate 522 connected to the first plate 521. The first plate 521 can be connected to the graphics card unit 80 via a first fastener, and the second plate 522 can be connected to the second fixing part 32 via a second fastener. The first fastener may include a screw, and the second fastener may also include a screw. The second plate 522 has a first connecting hole, and the second fixing part 32 has a plurality of second connecting holes spaced apart along a third direction. According to the length of the graphics card unit 80, the first connecting hole on the second plate 522 is aligned with one of the plurality of second connecting holes, and then the second plate 522 and the second fixing part 32 are connected via the second fastener, thereby connecting the second end of the graphics card unit 80 to the second fixing part 32. By adjusting the position of the second connector 52 on the second fixing part 32, the installation of graphics card units 80 of various specifications can be achieved.

[0155] When disassembly is required, the first and second fasteners can be removed to separate the second connector 52 from the graphics card unit 80.

[0156] In the embodiments disclosed herein, the second connector 52 includes a first body and a second plate 522 connected to each other. The first plate 521 is detachably connected to the graphics card unit 80 via a first fastener, and the second plate 522 is detachably connected to the second fixing part 32 via a second fastener. The second plate 522 can be connected to one of a plurality of connection positions on the second fixing part 32. The structure is simple and the installation and disassembly are convenient.

[0157] The following describes in detail the installation and removal process of the second installation component 50 and the graphics card unit 80.

[0158] The installation process is as follows: First, connect the connecting plate to the top of the graphics card unit 80. Place the graphics card unit 80 and the connecting plate inside the housing 10. Adjust the second plate 522 so that the first connecting hole on the second plate 522 and the second connecting hole on the second fixing part 32 are aligned. Tighten the second fastener into the first connecting hole and the second connecting hole to connect the second connecting member 52 and the second fixing bracket 30. Apply a rotational force towards the inside of the housing 10 to the rotating part 512 of the first connecting member 51. After the rotating part 512 rotates to its position, the guide part 5122 of the rotating part 512 abuts against the moving part 511, and the abutting part 5121 abuts against the first end of the graphics card unit 80, thereby fixing the graphics card unit 80.

[0159] The disassembly process is as follows: Pull the moving part 511 outwards towards the outer side of the housing 10 in a third direction. The rotating part 512 flips outwards towards the outer side of the housing 10. After the rotating part 512 rotates to its position, the abutting part 5121 of the rotating part 512 separates from the graphics card unit 80, thus separating the first connecting part 51 from the graphics card unit 80. Remove the second fastener at the second plate 522, and remove the graphics card unit 80 and the second connecting part 52 from the housing 10. Remove the first fastener at the first plate 521, thereby disassembling the graphics card unit 80.

[0160] In embodiments of this disclosure, such as Figure 16 As shown, the chassis also includes a locking element 60. (As indicated...) Figure 1 , Figure 2 and Figure 23 As shown, the enclosure 10 includes an enclosure body 11 and an enclosure door 12 detachably connected to the enclosure body 11. The enclosure door 12 has an abutment portion 121. A locking member 60 is provided on the first fixing frame 20. The locking member 60 includes a driving member and a limiting rod 61. The driving member is used to drive the limiting rod 61 to switch between a third position and a fourth position. When the limiting rod 61 is switched to the third position, the limiting rod 61 abuts against the abutment portion 121, and the enclosure door 12 is locked to the enclosure body 11. When the limiting rod 61 is switched to the fourth position, the limiting rod 61 moves away from the abutment portion 121, and the enclosure door 12 can be separated from the enclosure body 11.

[0161] The enclosure 10 may include an enclosure body 11 and an enclosure door 12 detachably connected to the enclosure body 11, the enclosure door 12 being insertable into the enclosure body 11. The enclosure body 11 may include a first side wall 111, a second side wall 112, and a third side wall, the first side wall 111 and the second side wall 112 being spaced apart along a first direction. The enclosure door 12 is connected to the opening formed between the first side wall 111 and the second side wall 112, and the enclosure door 12 and the enclosure body 11 can be inserted into each other.

[0162] In some embodiments, the first sidewall 111 has a slot near the end of the door 12. The slot can be an elongated slot. The number of slots is set according to actual needs; for example, three slots are spaced apart along a third direction on the first sidewall 111. The door 12 has a plug-in portion that matches the slot. There can be three plug-in portions, with each of the three plug-in portions corresponding to one of the three slots. The plug-in portion can be inserted into the slot, thus limiting the position of the door 12.

[0163] In some embodiments, the bottom of the door 12 is provided with a support plate, and the support plate is provided with limiting posts 122. The number of limiting posts 122 can be one, two, or more. For example, there are two limiting posts 122, which are spaced apart at the bottom of the door 12 along a first direction. The first side of the first fixing frame 20 is provided with limiting holes, which are adapted to the limiting posts 122, and the two limiting posts 122 correspond one-to-one with the two limiting holes. The limiting posts 122 can be inserted into the limiting holes to limit the door 12.

[0164] In some embodiments, the first fixing frame 20 is provided with a locking member 60, which may include a solenoid valve lock. The solenoid valve lock includes a driving member and a limiting rod 61, and the driving member includes an electromagnetic coil. The door 12 is provided with an abutment portion 121, and the limiting rod 61 can abut against the abutment portion 121. When the electromagnetic coil is energized, the limiting rod 61 moves along a second direction toward the door 12 until the limiting rod 61 abuts against the abutment portion 121. When the electromagnetic coil is de-energized, the limiting rod 61 moves along the second direction away from the door 12, thereby separating the limiting rod 61 from the abutment portion 121.

[0165] The following describes the installation and removal process of the cabinet door 12.

[0166] The installation process is as follows: Insert the connector of the door 12 into the slot of the body 11 to initially position the door 12. Then, align the limiting post 122 on the door 12 with the limiting hole on the first fixing frame 20. Pull the door 12 upward in the third direction until the limiting post 122 is inserted into the limiting hole, and the support plate can fit against the bottom surface of the first fixing frame 20. After that, control the electromagnetic coil to be energized, and the limiting rod 61 moves in the second direction to abut against the contact part 121 on the door 12, restricting the door 12 from moving downward in the third direction, thereby locking the door 12 to the door of the body 10.

[0167] The disassembly process is as follows: the control electromagnetic coil is de-energized, the limit rod 61 moves along the second direction until it separates from the contact part 121 on the box door 12, the box door 12 moves downward along the third direction until the limit post 122 moves out of the limit hole, and then the box door 12 is pulled outward to separate the box door 12 from the box body 11.

[0168] In the embodiments disclosed herein, the door 12 is initially positioned by inserting it into the body 11 of the box. The driving member drives the limiting rod 61 to move along the second direction until it abuts against the contact part 121 on the door 12, thereby locking the door 12 to the body 11. The driving member drives the limiting rod 61 to move along the second direction until it separates from the contact part 121 on the door 12. After the door 12 moves downward along the third direction for a certain distance, it can be separated from the body 11, which facilitates the convenience of installation and disassembly.

[0169] In embodiments of this disclosure, such as Figure 2 As shown, the second mounting bracket 30 is used to mount at least one fan unit 70, and the fan unit 70 mounted at the second mounting bracket 30 is used to allow outside air to flow into the housing 10. The fan unit 70 on the first mounting assembly 40 is used to exhaust air from inside the housing 10 to the outside of the housing 10.

[0170] In some embodiments, fan units 70 may be installed on the second mounting bracket 30, and the number of fan units 70 is set according to actual needs. The number of fan units 70 can be one, two, or more, and the number and position of fan units 70 on the second mounting bracket 30 can be flexibly set. For example, the number of fan units 70 is three: two fan units 70 are installed on the top side of the second mounting bracket 30, that is, two fan units 70 are located on the side of the second mounting bracket 30 away from the first mounting bracket 20; one fan unit 70 is installed on the bottom side of the second mounting bracket 30, that is, one fan unit 70 is located on the side of the second mounting bracket 30 facing the first mounting bracket 20.

[0171] The number of first mounting components 40 can be one, two, or more. For example, the number of first mounting components 40 can be two, and the two first mounting components 40 are spaced apart along a first direction. Two fan units 70 can be mounted on the bracket 41 of the first mounting components 40, so that four fan units 70 are located in the first region.

[0172] An air inlet can be provided on the top wall of the enclosure 10, and multiple fan units 70 on the first mounting bracket 20 allow outside air to flow into the enclosure 10 through the air inlet on the top wall. An exhaust port can be provided on the door 12, and multiple fan units 70 on the bracket 41 allow air inside the enclosure 10 to be exhausted to the outside of the enclosure 10 through the exhaust port. The multiple fan units 70 installed on the first mounting bracket 20 and the multiple fan units 70 installed on the bracket 41 help improve the heat dissipation performance of the enclosure; the number of fan units 70 can be flexibly configured according to usage requirements.

[0173] In the embodiments of this disclosure, multiple fan units 70 can be installed on the first mounting bracket 20 and multiple fan units 70 can be installed on the first mounting assembly 40, which helps to accelerate the airflow inside the chassis 10 and improve the heat dissipation performance of the chassis.

[0174] In some embodiments, the first mounting bracket 20 can serve as the bottom wall of the enclosure 10. Support legs are provided at the bottom of the first mounting bracket 20, with two support legs spaced apart along a first direction at the bottom of the first mounting bracket 20. An accommodating space is formed below the bottom surface of the first mounting bracket 20. Functional modules of the electronic device can be mounted on the first mounting bracket 20. These functional modules may include a power interface, a USB interface, an audio input / output interface, a network port, etc. The functional modules are located on the first mounting bracket 20, providing a degree of concealment and contributing to the overall aesthetics of the enclosure. Cables and data cables connected to the functional modules can be routed out from the accommodating space.

[0175] This disclosure also provides an electronic device, which includes a chassis, a fan unit 70, a graphics card unit 80, a processing unit, a motherboard, etc. Figures 2 to 4 As shown, the chassis includes a housing 10, a first mounting bracket 20, a second mounting bracket 30, a first mounting assembly 40, and a second mounting assembly 50. The first mounting bracket 20 is disposed on the housing 10 and has intersecting first and second directions. The second mounting bracket 30 is disposed on the housing 10 and spaced apart from the first mounting bracket 20 along a third direction. A first region and a second region are formed between the first mounting bracket 20 and the second mounting bracket 30. The first region and the second region are different, and the third direction is perpendicular to the first and second directions. The first mounting assembly 40 is disposed in the first region and extends along the first direction. One end of the first mounting assembly 40 is rotatably connected to the first mounting bracket 20, and the other end is locked to the second mounting bracket 30. The first mounting assembly 40 is used to mount a fan unit 70 of electronic equipment. The second mounting assembly 50 is disposed in the second region and extends along the second direction. One end of the second mounting assembly 50 is movably connected to the first mounting bracket 20, and the other end is movablely connected to the second mounting bracket 30. The second mounting assembly 50 is used to mount a graphics card unit 80 of electronic equipment.

[0176] As described above, the chassis structure includes a chassis 10, a first mounting bracket 20 and a second mounting bracket 30 disposed within the chassis 10. One end of the first mounting component 40 is rotatably connected to the first mounting bracket 20, and the other end is locked to the second mounting bracket 30. The first mounting component 40 is used to mount the fan unit 70. One end of the second mounting component 50 is movably connected to the first mounting bracket 20, and the other end is movablely connected to the second mounting bracket 30. The second mounting component 50 is used to mount the graphics card unit 80.

[0177] The graphics card unit 80 is installed inside the case 10. During the assembly process, the graphics card unit 80 is installed first, followed by the first mounting component 40 and the fan unit 70.

[0178] The process of installing the graphics card unit 80 is as follows: connect the second connector 52 to the second end of the graphics card unit 80, place the graphics card unit 80 and the second connector 52 in the second area inside the housing 10, and then connect the second connector 52 to the second mounting bracket 30 with fasteners; then apply a rotation action to the first connector 51, so that the first connector 51 rotates to abut against the first end of the graphics card unit 80, thereby fixing the graphics card unit 80 on the first mounting bracket 20 and the second mounting bracket 30.

[0179] The fan unit 70 is installed on the bracket 41 of the first mounting component 40. The installation process of the first mounting component 40 is as follows: one end of the bracket 41 is placed at the mounting position of the first fixing frame 20. At this time, the bracket 41 is tilted relative to the housing 10. The bracket 41 is rotated from the tilted position to a position that is approximately parallel to the housing 10, that is, the bracket 41 is in a vertical position. After the bracket 41 is rotated into place, the other end of the bracket 41 is locked with the second fixing frame 30, thereby fixing the first mounting component 40 on the first fixing frame 20 and the second fixing frame 30.

[0180] The process of disassembling the fan unit 70 and the graphics card unit 80 is as follows: first, disassemble the first mounting component 40 and the fan unit 70, and then disassemble the graphics card unit 80.

[0181] When disassembling the first mounting component 40, the other end of the bracket 41 can be unlocked from the second fixing frame 30 by pressing. Then, the bracket 41 is rotated from a vertical position to an inclined position. After the bracket 41 is rotated into place, one end of the bracket 41 can be separated from the first fixing frame 20.

[0182] When disassembling the graphics card unit 80, the fasteners connecting the second connector 52 to the second mounting bracket 30 are removed. The first connector 51 can be rotated to separate the first connector 51 from the graphics card unit 80. The graphics card unit 80 and the second connector 52 are then removed from the housing 10. After that, the fasteners connecting the second connector 52 to the graphics card unit 80 are removed, thus completing the disassembly of the graphics card unit 80.

[0183] By applying a rotation or pressing action to the first mounting component 40, the first mounting component 40 can be fixed to the first fixing frame 20 and the second fixing frame 30, or the first mounting component 40 can be removed from the first fixing frame 20 and the second fixing frame 30, which facilitates the installation and removal.

[0184] The second connector 52 is movably connected to the second mounting bracket 30 in a third-order direction. The installation position of the second connector 52 and the second mounting bracket 30 can be flexibly adjusted according to the length of the graphics card unit 80 to accommodate graphics card units 80 of different lengths. The first connector 51 abuts against or separates from the bottom of the graphics card unit 80 under external force. The second connector 52 is connected to the top of the graphics card unit 80 and is movably connected to the second mounting bracket 30. This facilitates the installation and removal of the graphics card unit 80 and allows for the installation of graphics card units 80 of different sizes.

[0185] The electronic device with the aforementioned chassis can be installed or removed by applying rotation or pressing actions, which facilitates the installation and removal of the first mounting component 40 and the fan unit 70. One end of the second mounting component 50 can abut or separate from the bottom of the graphics card unit 80 under external force, and the other end of the second mounting component 50 is movably connected to the second fixing bracket 30, which not only facilitates the installation and removal of the graphics card unit 80, but also allows for the installation of graphics card units 80 of different models and sizes.

[0186] In some embodiments, the first mounting assembly 40 includes a bracket 41, a limiting structure 42 is provided at the first end of the bracket 41, and a limiting member 21 is provided on the first fixing frame 20; a locking structure 43 is provided at the second end of the bracket 41, and a first locking part 33 is provided on the second fixing frame 30. The installation and disassembly process of the first mounting assembly 40 and the fan unit 70 will be described in detail below.

[0187] The installation process is as follows: The first end of the bracket 41 is placed on the first fixed frame 20. The first protrusions 421 of the two limiting structures 42 are respectively located in the limiting grooves 2121 of the two limiting members 21. A flipping force is applied to the bracket 41 towards the inside of the housing 10, causing the bracket 41 to rotate from an inclined posture to a near-vertical posture. At the first end of the bracket 41, the limiting structure 42 rotates relative to the limiting member 21 to the first posture, and the second protrusion 422 rotates to face the first surface 2122 of the limiting member 21. The limiting structure 42 is relatively fixed at the limiting member 21, thus connecting the first end of the bracket 41 to the first fixed frame 20. At the second end of the bracket 41, the first locking part 33 and the second locking part 432 press against each other. The second locking part 432 moves along a third direction to the second position. During the process of returning to the first position under the rebound force of the elastic member 434, the second locking part 432 and the first locking part 33 are locked, thus connecting the second end of the bracket 41 to the second fixed frame 30. This allows the fan unit 70 to be installed.

[0188] The disassembly process is as follows: Press down on the force-applying part 433, and the second locking part 432 moves downward along the third direction to the second position, unlocking the second locking part 432 from the first locking part 33. Then, apply an outward flipping force to the bracket 41, and the bracket 41 rotates from a vertical position to an inclined position. The limiting structure 42 rotates relative to the limiting member 21 to the second position, and the second protrusion 422 rotates to face the second surface 2123 of the limiting member 21. The limiting structure 42 and the limiting member 21 can be separated, thereby allowing the first mounting assembly 40 and the fan unit 70 to be removed from the first fixing bracket 20 and the second fixing bracket 30.

[0189] In some embodiments, the second mounting assembly 50 includes a first connector 51 and a second connector 52. The first connector 51 includes a movable member 511 and a rotating member 512. The second connector 52 includes a connecting plate, which includes a first plate body 521 connected to the graphics card unit 80 and a second plate body 522 connected to the second fixing part 32. The installation and removal process of the graphics card unit 80 is described in detail below.

[0190] The installation process is as follows: First, connect the connecting plate to the top of the graphics card unit 80. Place the graphics card unit 80 and the connecting plate inside the housing 10. Adjust the second plate 522 so that the first connecting hole on the second plate 522 and the second connecting hole on the second fixing part 32 are aligned. Tighten the second fastener into the first connecting hole and the second connecting hole to achieve the connection between the second connecting member 52 and the second fixing bracket 30. Apply a rotational force towards the inside of the housing 10 to the rotating part 512 of the first connecting member 51. After the rotating part 512 rotates into place, the guide part 5122 of the rotating part 512 abuts against the moving part 511, and the abutting part 5121 abuts against the bottom of the graphics card unit 80, thereby realizing the installation of the graphics card unit 80.

[0191] The disassembly process is as follows: Moving component 511 along a third direction towards the outside of housing 10 causes rotating component 512 to rotate outwards towards housing 10. After rotating component 512 reaches its position, its abutting portion 5121 separates from the graphics card unit 80, thus separating the first connecting component 51 from the graphics card unit 80. The second fastener at the second plate 522 is then removed, allowing the graphics card unit 80 and the second connecting component 52 to be taken out of housing 10. Finally, the first fastener at the first plate 521 is removed, thereby disassembling the graphics card unit 80.

[0192] The graphics card unit 80 is detachably connected to the second area inside the case 10 via the first connector 51 and the second connector 52; the fan unit 70 is detachably connected to the first area inside the case 10 via the bracket 41, the limiting structure 42 and the locking structure 43, making installation and disassembly convenient; in addition, the overall structure is compact, which is conducive to the reasonable layout of components inside the case 10.
