Description

Chassis with quick-release display device Technical Field

[0001] This utility model relates to the field of chassis, specifically to a chassis with a quick-release display device. Background Technology

[0002] Computer chassis are widely used in various fields, including but not limited to computers and servers. For example, computer chassis primarily provide physical support and protection for internal hardware. With the rapid development of computer technology, the function and design of computer chassis, as a crucial component supporting computer hardware, are constantly evolving. To meet the increasingly diverse needs of users, many chassis are now equipped with display devices. These displays provide users with additional information interfaces, such as showing system operating status (e.g., temperature, fan speed, hardware operating status), personalized information (e.g., time, weather, custom icons), facilitating basic computer operations.

[0003] Currently, computer cases on the market primarily use screws or magnetic attachment to secure monitors. Screw attachment typically requires multiple screw holes in corresponding locations on both the case and the monitor, firmly fixing the screen to the case. While this method ensures stability, it requires tools like screwdrivers for installation and removal, making the process relatively cumbersome and time-consuming. Magnetic attachment, on the other hand, uses magnets to hold the monitor to the case. Although tool-free installation and removal are convenient, the magnetic force is relatively limited. The monitor is prone to detaching under impact or vibration, exhibiting poor stability and posing a safety hazard, thus affecting the reliable use of the display device. Summary of the Invention

[0004] The purpose of this utility model is to solve the above-mentioned defects and provide a chassis with a quick-release display device, so as to solve the technical problems in the prior art where the installation and fixation of the display device on the computer chassis is not easy to be quickly disassembled and assembled, and the magnetic installation has poor stability, thus affecting the stable use and ease of disassembly of the display device.

[0005] The objective of this utility model is achieved through the following means:

[0006] A chassis with a quick-release display device includes a chassis body. A display device is mounted on the side of the chassis body. The display device includes a housing, a display screen, a circuit board, and a back cover. A mounting bracket is connected to the side of the chassis body via a support frame. The mounting bracket has a mounting groove for mounting the display device. A raised positioning protrusion is provided on the side of the housing body. The inner wall of the mounting groove has a positioning slot that engages with the positioning protrusion. A top post is connected to the back of the support frame via an ejector mounting seat. An ejector elastic element is fitted onto the top post to provide a continuous ejection force. The support frame is connected to the mounting base via a support. A sliding gap is provided between the support and the mounting base to communicate with the mounting groove. A locking tongue is provided in the sliding gap to slide into the mounting groove. The side of the outer shell is provided with a locking groove to engage with the locking tongue. The end of the locking tongue away from the mounting groove is connected to a tongue elastic element that applies a pushing force to the locking tongue. A button is provided on the mounting base. A ramp is provided on the back of the button. A sliding groove is provided on the locking tongue. The ramp passes through the fixed base and engages with the sliding groove. A reset elastic element is sleeved on the button.

[0007] When the button is pressed, the locking tongue retracts towards the tongue elastic element, causing the locking tongue to release from the locking groove. The ejector elastic element drives the top column to eject and reset, and the display device is ejected from the mounting groove.

[0008] Furthermore, as described above, the ejector fixing seat is installed on the back of the support frame, and the top column is installed on the side of the ejector fixing seat. The top column passes through the mounting bracket and protrudes into the mounting groove through the elastic force of the ejector elastic element. When the display device mates with the positioning slot through the positioning protrusion, the display device is pressed into the mounting groove, and the locking tongue is squeezed and retracts towards the tongue elastic element. The ejector elastic element generates compression, which drives the top column to retract. At this time, the locking tongue is locked and paired with the locking groove under the elastic reset of the tongue elastic element.

[0009] By combining the ejector mounting base with the ejector elastic element, the display device is automatically ejected from the mounting slot during disassembly using the elastic restoring characteristic of the elastic element. This solves the cumbersome operation problem of traditional screw fixing requiring repeated tightening with tools, while also avoiding the hidden danger of magnetic fixing easily falling off due to external force.

[0010] Furthermore, as described above, the snap-fit ​​groove and the positioning protrusion are distributed opposite to each other on both sides of the outer casing, and the inner wall of the mounting groove is provided with a through clearance opening.

[0011] The compression and reset action of the ejector elastic element directly acts on the display device. When the display device is pressed for installation, the linkage contraction mechanism between the locking tongue and the top post ensures the smoothness of the installation process. At the same time, when pressed to the corresponding position, the opening of the retaining groove allows the locking tongue to engage with the retaining groove under the elastic reset of the tongue elastic element, effectively solving the problem of easy loosening of magnetic fixation, while retaining the convenience of quick disassembly.

[0012] Furthermore, as described above, the support is provided with a movable groove that matches the locking tongue. One end of the movable groove is connected to the clearance groove and the mounting groove, so that one end of the locking tongue passes through the clearance opening and is exposed in the mounting groove under the elastic force of the tongue elastic element. The end of the locking tongue near the mounting groove is provided with an inclined part.

[0013] The relative distribution of the snap-fit ​​slots and positioning protrusions forms a dual-point fixing structure. Combined with the conductive design of the opening in the inner wall of the mounting slot, the positioning protrusions enable precise guidance of the display device during installation, while the snap-fit ​​slots and locking tongues provide lateral constraint. This improves the reliability and stability of the connection between the display device and the cabinet.

[0014] The through-type design of the moving groove and the clearance opening on the support provides a linear motion track for the locking tongue, ensuring its stable extension and retraction along a predetermined path. The inclined part is designed as a guide surface for the locking tongue when the housing is inserted, allowing the display device to automatically push open the locking tongue when pressed, completing the installation without the need for precise alignment.

[0015] Furthermore, as described above, the mounting bracket has a pressing opening that matches the button. The front of the button is exposed outside the mounting bracket through the pressing opening. The side of the ramp has an inclined surface, so that pressing the button can drive the locking tongue to retract along the slide groove through the ramp. The reset elastic element is sleeved on the ramp.

[0016] The inclined surface design of the button ramp and the slide groove converts the vertical pressing force into the contraction force of the locking tongue. The automatic rebound function of the reset elastic element ensures the repeatability of the operation. At the same time, the locking tongue forms a locking with the locking groove when reset, ensuring the stability and convenience of the locking installation.

[0017] Furthermore, as described above, the ejector elastic element, the tongue elastic element, and the reset elastic element are all composed of springs.

[0018] Furthermore, as described above, the back cover is mounted on the back of the housing, the circuit board is located between the housing and the back cover, and the display screen is mounted on the housing and electrically connected to the circuit board.

[0019] The paired installation design of the back cover and the outer shell forms a closed protective structure, avoiding the risk of short circuits caused by exposed circuit boards. The modular design enables convenient disassembly and maintenance of the display device, solving the problem of the relatively complex disassembly and assembly structure of traditional chassis display modules.

[0020] The beneficial effects of this utility model are as follows: The display device is paired with the mounting slot, and the positioning protrusion at one end is precisely engaged with the positioning slot. By pressing the display device, it is inserted into the mounting slot. When the display is pressed, the top post is compressed by the elastic element, causing the top post to disengage from the mounting slot. At the same time, the locking tongue is squeezed away from the display device, and the locking slot mates with the locking tongue. Under the elastic reset of the tongue's elastic element, the locking tongue moves along the sliding gap towards the mounting slot and inserts into the locking slot, thereby completing the locking installation of the display device and ensuring the convenience and stability of the display device installation connection. Conversely, when the button is pressed, the button drives the locking tongue to disengage from the locking slot through the inclined platform. Under the elastic reset of the ejection reset element, the top post ejects the display device, thereby quickly completing the disassembly of the display device. The overall operation is simple, and disassembly can be completed by pressing the button with one hand, improving the convenience of operation. Attached Figure Description

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0029] This embodiment, referring to Figures 1-6, specifically implements a chassis with a quick-release display device, including a chassis 1. A display device is mounted on the side of the chassis 1. The display device includes a housing 2, a display screen 3, a circuit board 4, and a back cover 5. A mounting bracket 7 is connected to the side of the chassis 1 via a support frame 6. The mounting bracket 7 has a mounting groove 8 for mounting the display device. A raised positioning protrusion 9 is provided on the side of the housing 2. The inner wall of the mounting groove 8 has a positioning slot 10 that engages with the positioning protrusion 9. A top post 11 is connected to the back of the support frame 6 via a push-out fixing seat 26. A push-out elastic element 1 is fitted onto the top post 11 to provide a continuous push-out elastic force. 2. A mounting base 14 is connected to the support frame 6 via a support 13. A sliding gap is provided between the support 13 and the mounting base 14 to communicate with the mounting groove 8. A locking tongue 15 that can slide into the mounting groove 8 is provided in the sliding gap. A snap-fit ​​groove 16 is provided on the side of the outer shell 2 to engage with the locking tongue 15. A tongue elastic element 17 that applies a push-out elastic force to the locking tongue 15 is connected to the end of the locking tongue 15 away from the mounting groove 8. A button 18 is provided on the mounting base 14. A ramp 19 is provided on the back of the button 18. A sliding groove 20 is provided on the locking tongue 15. The ramp 19 passes through the fixed base and engages with the sliding groove 20. A reset elastic element 21 is sleeved on the button 18.

[0030] When button 18 is pressed, the locking tongue 15 retracts towards the tongue elastic member 17, causing the locking tongue 15 to release from the locking groove, and the ejector elastic member 12 drives the ejector pin 11 to eject and reset, so that the display device is ejected from the mounting groove 8.

[0031] In the specific implementation process, when the button 18 is pressed, the reset elastic member 21 is compressed, and the inclined platform 19 forms an inclined surface at one end near the tongue elastic member 17, so that the button 18 can move the locking tongue 15 towards the tongue elastic member 17 under the action of the slide groove 20, thereby quickly removing the locking tongue 15 from the locking groove 16.

[0032] The ejector fixing seat 26 is installed on the back of the support frame 6, and the top post 11 is installed on the side of the ejector fixing seat 26. The top post 11 passes through the mounting bracket 7 and is exposed in the mounting groove 8 by the elastic force of the ejector elastic member 12. When the display device is paired with the positioning slot 10 through the positioning protrusion 9, the display device is pressed into the mounting groove 8. The locking tongue 15 is squeezed and retracts towards the tongue elastic member 17. The ejector elastic member 12 generates compression and drives the top post 11 to retract. At this time, the locking tongue 15 is locked and paired with the locking groove under the elastic reset of the tongue elastic member 17.

[0033] In the specific implementation process, through the cooperative design of the ejector fixing seat 26 and the ejector elastic element 12, the display device is automatically ejected from the mounting slot 8 by utilizing the elastic reset characteristic of the elastic element during disassembly. This solves the cumbersome operation problem of traditional screw fixing requiring repeated turning with tools, and avoids the hidden danger of magnetic fixing easily falling off due to external force.

[0034] The snap-fit ​​groove 16 and the positioning protrusion 9 are distributed opposite to each other on both sides of the outer shell 2, and the inner wall of the mounting groove 8 is provided with a through clearance opening 22.

[0035] In the specific implementation process, the compression and reset action of the ejector elastic element 12 directly acts on the display device. When the display device is pressed and installed, the linkage contraction mechanism of the locking tongue 15 and the top post 11 ensures the smoothness of the installation process. At the same time, when pressed to the corresponding position, the opening of the retaining groove allows the locking tongue 15 to engage with the retaining groove under the elastic reset of the tongue elastic element 17, so that it is relatively set with the positioning protrusion 9, further ensuring the stability and reliability of the display device installation, solving the problem of easy loosening of magnetic fixation, while retaining the convenience of quick disassembly.

[0036] The support 13 is provided with a movable groove 23 that matches the locking tongue 15. One end of the movable groove 23 is connected to the clearance groove and the mounting groove 8, so that one end of the locking tongue 15 is driven by the elastic force of the tongue elastic element 17 to pass through the clearance opening 22 along the movable groove 23 and be exposed in the mounting groove 8. The end of the locking tongue 15 near the mounting groove 8 is provided with an inclined part 24.

[0037] In the specific implementation process, the movable groove 23 is used to match and install the locking tongue 15, so that the locking tongue 15 can pass through the clearance opening 22 along the movable groove 23 and engage with the locking groove 16 for locking and limiting.

[0038] The relative distribution design of the snap-fit ​​groove 16 and the positioning protrusion 9 forms a dual-point fixing structure. Combined with the conduction design of the clearance opening 22 on the inner wall of the mounting groove 8, the display device is precisely guided by the positioning protrusion 9 during installation, and a lateral constraint is formed by the snap-fit ​​groove 16 and the locking tongue 15. This improves the reliability and stability of the connection between the display device and the cabinet 1.

[0039] The through-type design of the movable groove 23 and the clearance opening 22 on the support 13 provides a linear motion track for the locking tongue 15, ensuring its stable extension and retraction along a predetermined path. The inclined part 24 is configured as a guide surface for the locking tongue 15 when the housing 2 is inserted, so that the display device can automatically push open the locking tongue 15 through the inclined part 24 when pressed, and the installation action can be completed without precise alignment.

[0040] The mounting bracket 7 has a pressing opening 25 that matches the button 18. The front of the button 18 is exposed outside the mounting bracket 7 through the pressing opening 25. The side of the inclined platform 19 has an inclined surface, so that pressing the button 18 can drive the locking tongue 15 to retract along the slide groove 20 through the inclined platform 19. The reset elastic element 21 is sleeved on the inclined platform 19.

[0041] In the specific implementation process, the inclined surface design of the ramp 19 of button 18 and the slide 20 converts the vertical pressing force into the contraction force of the locking tongue 15. The automatic rebound function of the reset elastic element 21 on button 18 ensures the repeatability of operation. At the same time, it makes the locking tongue 15 form a locking with the locking groove 16 under the reset state, ensuring the stability and convenience of the locking installation.

[0042] Specifically, in this embodiment, the ejector elastic element 12, the tongue elastic element 17, and the reset elastic element 21 are all composed of springs.

[0043] The back cover 5 is mounted on the back of the outer shell 2, the circuit board 4 is located between the outer shell 2 and the back cover 5, and the display screen 3 is mounted on the outer shell 2 and electrically connected to the circuit board 4.

[0044] The mating installation design of the back cover 5 and the outer shell 2 forms a closed protective structure, which avoids the risk of short circuits caused by exposed circuit board 4. The modular design enables convenient disassembly and maintenance of the display device, solving the problem of the relatively complex disassembly and assembly structure of the chassis display module.

[0045] The specific usage process in this embodiment is as follows:

[0046] Installation and Locking: The support frame 6 is set on one side of the housing 1, and the mounting bracket 7 is connected to the support frame 6 by bolts. The display device is paired with the mounting slot 8, and the positioning protrusion 9 on the housing 2 is precisely locked and matched with the positioning slot 10. The display device is pressed and inserted into the mounting slot 8. When the display is pressed, the top post 11 is compressed by the pressure of the display device, and the elastic member 12 is pushed out to disengage the top post 11 from the mounting slot 8. At the same time, the locking tongue 15 is squeezed away from the display device by the inclined part 24, so that the locking slot 16 is connected to the clearance opening 22. Under the elastic reset of the tongue elastic member 17, the locking tongue 15 passes through the clearance opening 22 along the sliding gap and is inserted into the locking slot 16, thereby completing the locking and installation of the display device and ensuring the convenience and stability of the display device installation and connection.

[0047] Unlocking and disassembly: When button 18 is pressed, button 18 drives the locking tongue 15 to disengage from the locking groove 16 via the inclined platform 19. At this time, the display device lacks the locking of the locking tongue 15, thus it can be loosened. Under the elastic reset of the ejection reset component, the top post 11 will eject the display device from the installation groove 8. The positioning protrusion 9 can be disengaged from the positioning groove 10 by hand, thus the disassembly of the display device can be completed quickly. The overall operation is simple, and disassembly can be completed by pressing button 18 with one hand, which improves the convenience of operation.

[0048] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
