Description

Technical Field

[0001] This invention relates to the field of computer chassis technology, specifically to a computer chassis that facilitates the installation of a motherboard. Background Technology

[0002] A computer chassis is the physical enclosure that houses and protects the core hardware of a computer (motherboard, power supply, storage, etc.). Its technological development has evolved from focusing solely on physical protection and support in its early stages to a comprehensive solution integrating heat dissipation management, electromagnetic shielding, expansion compatibility, and aesthetic customization. Based on motherboard size and form factor, it has formed standard classifications such as full-tower, mid-tower, mini-tower, and miniaturized models, forming the foundation for the stable operation of modern computers.

[0003] Patent publication number CN109976468B relates to a dustproof computer chassis, including a chassis body, a dust filter disposed on the chassis body, a cleaning device disposed on the chassis body for cleaning the dust filter, and a dust removal device connected to the cleaning device for discharging dust from the chassis body. This patented dustproof computer chassis, by incorporating the cleaning device and dust removal device, promptly removes dust from inside the chassis, improving the chassis's ventilation and heat dissipation efficiency.

[0004] However, existing computer cases do not involve the installation of the internal motherboard. When installing the case, the support bracket for fixing the motherboard is usually located deep inside the case. When the staff operates, they need to open the case door and place the motherboard deep inside the case to fix it. They need to reach into the case to operate, which is very inconvenient. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a computer chassis that facilitates motherboard installation, thus solving the problems mentioned in the background section.

[0006] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a computer chassis for convenient motherboard installation, comprising a base, a shell fixedly connected to the top of the base, a cover plate rotatably connected to the front of the shell, a fixing post rotatably connected to the inner wall of the shell, a push plate and a mounting bracket slidingly penetrating the circumferential surface of the fixing post, a first spring provided between the push plate and the mounting bracket, a door opening and fixing device provided on the outer wall of the shell, the door opening and fixing device comprising a fixing plate, a fixing cylinder, a fixing block and a round bolt, the fixing plate being fixedly connected to the side of the cover plate away from the shell, the fixing cylinder being fixedly connected to the upper surface of the fixing plate, the fixing block being fixedly connected to the left side of the shell near the fixing plate, the round bolt slidingly penetrating the upper and lower surfaces of the fixing block, and a portable installation device provided inside the shell, the portable installation device comprising an arc block, an arc plate and a blocking block. The system comprises a second blocking block, a wedge block, a push rod, an L-shaped rod, and a second push plate. The arc block is fixedly connected to the side of the cover plate near the fixed post. The arc plate slides through the end of the arc block away from the cover plate. The blocking block slides through the side of the arc block away from the mounting bracket. A groove is provided on the left side of the arc plate, and the blocking block contacts the groove on the arc plate. The second blocking block is fixedly connected to the bottom of the inner wall of the outer casing. The wedge block slides through the top surface of the second blocking block. A wedge is provided on the side of the wedge block near the outer casing. The push rod slides through the inner and outer walls of the outer casing. The L-shaped rod is slidably connected to the bottom of the inner wall of the outer casing and is rotatably connected to the arc plate. The second push plate is fixedly connected to the end of the L-shaped rod away from the arc plate. When the cover plate is opened, the mounting bracket will be pushed out through the arc block and the second push plate, making it easier to install the computer motherboard on the mounting bracket and avoiding the inconvenience of installing the motherboard inside the small chassis.

[0007] According to the above scheme: a second spring is provided at the connection between the round bolt and the fixed block. The second spring resets the round bolt. The arc plate has a groove that contacts the blocking block. The blocking block has an arc groove that can be driven away from the groove of the arc plate when it contacts the second blocking block. A third spring is provided between the second blocking block and the inclined block. The third spring resets the inclined block.

[0008] According to the above scheme: the casing is equipped with an anti-damage device, which includes a third blocking block, a second inclined block, a telescopic rod, and the third inclined block. The third blocking block is fixedly connected to the side of the push plate near the mounting bracket. The second inclined block is slidably connected to the side of the mounting bracket near the push plate. The telescopic rod is fixedly connected to the bottom of the second inclined block. The third inclined block is fixedly connected to the bottom of the inner wall of the casing. The arc block and the arc plate inside the arc block are not restricted by the blocking block and can extend and retract, so that the mounting bracket will not be pulled out when the cover is opened, preventing the mounting bracket from being accidentally pulled out and colliding with the motherboard and other computer components installed on the motherboard.

[0009] According to the above scheme: the damage prevention device further includes a pressure plate, an arc plate II, an arc block II, a stop block, and a pressure rod. The pressure plate is fixedly connected to the circumferential surface of the fixed end of the telescopic rod. The arc plate II is fixedly connected to the end of the pressure plate away from the telescopic rod. The arc block II is fixedly connected to the side of the cover plate near the fixed post. The arc plate II slides through the interior of the arc block II. The stop block is fixedly connected to the arc surface of the arc block II near the push rod. One end of the pressure rod is rotatably connected to the top of the stop block. The other end of the pressure rod near the arc block II contacts the stop block. The push plate drives the stop block III to squeeze the inclined block II, causing the inclined block II to slide downward. The inclined block II pushes the telescopic rod down. The telescopic rod descends and stops the inclined block III, preventing the cover plate from opening. This alerts the operator that there is a foreign object blocking the front of the mounting bracket, preventing carelessness by the staff from damaging the motherboard and other computer components.

[0010] According to the above scheme: a No. 4 spring is installed between the inclined block 2 and the mounting bracket. The No. 4 spring allows the inclined block 2 to return to its original position after sliding down.

[0011] According to the above scheme: an anti-theft device is installed inside the outer casing. The anti-theft device includes a hole block, a sliding block, a T-shaped rod, a second push rod, a locking block, a pin, and a second sliding block. The hole block is fixedly connected to the side of the cover plate near the fixed post. The sliding block is slidably connected to the right side of the inner wall of the hole block. The T-shaped rod passes through the inner and outer walls of the right side of the outer casing. The second push rod is fixedly connected to the end of the T-shaped rod that passes through the inside of the outer casing. The locking block is fixedly connected to the inner wall of the outer casing near the T-shaped rod. The pin slides through the inner and outer surfaces of the locking block. The second sliding block slides through the left side of the locking block. A spiral spring is installed at the connection between the T-shaped rod and the outer casing. When the hole block strikes the second sliding block, the second sliding block slides into the locking block. After the hole block passes, the second sliding block immediately springs into the hole block, preventing the cover plate from being opened by pushing, pulling, or other conventional actions. Even when subjected to external force, the cover plate remains firmly locked to the outer casing, thereby achieving anti-theft protection for the inside of the equipment.

[0012] According to the above scheme: the anti-theft device also includes a second telescopic rod, a strip plate, a T-shaped plate, a long plate, a fixed rod, a third elastic telescopic rod, and a right-angle block. The second telescopic rod is fixedly connected to the bottom of the inner wall of the outer casing. The strip plate is fixedly connected to the free end of the second telescopic rod. The T-shaped plate is slidably connected to the inner wall of the outer casing near the T-shaped rod. A No. 6 spring is provided between the T-shaped plate and the outer casing. The long plate is fixedly connected to the end of the T-shaped plate away from the inner wall of the outer casing. The fixed rod is fixedly connected to the bottom of the long plate. The third elastic telescopic rod is fixedly connected to the inner wall of the right side of the outer casing. The telescopic end of the third elastic telescopic rod has a groove and contacts the long plate. The right-angle block is fixedly connected to the top of the telescopic end of the third elastic telescopic rod. The extended end of the third elastic telescopic rod drives the right-angle block to fix the mounting bracket and the motherboard mounted on the mounting bracket, so that even if the chassis is stolen, the cover cannot be easily opened. Even if the cover is forcibly opened, the more valuable motherboard cannot be removed without damaging the motherboard.

[0013] According to the above scheme: a No. 5 spring is provided between the locking block and the inclined slider 2, and the No. 5 spring can reset the inclined slider 2 after it slides.

[0014] (III) Beneficial Effects This invention provides a computer case that facilitates motherboard installation. It offers the following advantages: (1) When the cover is opened by manually pushing the push rod, the mounting bracket will be pushed out by the arc block and the second push plate, making it easier to install the computer motherboard on the mounting bracket and avoiding the inconvenience of installing the motherboard in the narrow chassis.

[0015] (2) When the cover is opened without pushing the push rod, the arc block and the arc plate inside the arc block are not restricted by the block and can extend and retract, so that the cover will not pull out the mounting bracket when it is opened. This means that when the operator wants to pull out the mounting bracket, the mounting bracket will be pulled out as the cover is opened. When the operator only wants to open the cover without using the mounting bracket, the mounting bracket will not pop out as the cover is opened.

[0016] (3) When the cover is opened and the mounting bracket pops out even though there is a component blocking it in front of the mounting bracket, the push plate drives the three-block block to squeeze the two-slope block, causing the two-slope block to slide down. The two-slope block pushes the telescopic rod down, and the telescopic rod goes down and stops the three-slope block, preventing the cover from opening. This reminds the operator that there is a foreign object blocking the front of the mounting bracket, thus preventing the operator from being careless and damaging the motherboard and other computer components.

[0017] (4) In this invention, when the telescopic rod descends and abuts against the inclined block three, the telescopic rod descends and simultaneously drives the pressure plate to descend. The pressure plate presses down and causes the abutment block to press down. The abutment block presses the pressure rod, and the pressure rod causes the blocking block to slide out of the groove of the arc plate, releasing the limitation on the arc plate. After the operator is reminded that there are foreign objects in front of the mounting frame, the cover plate can be opened normally without causing the mounting frame to pop out. Thus, the operator can clean up the foreign objects that are blocking the movement of the mounting frame normally.

[0018] (5) When the cover is closed, the hole block hits the inclined slider two, causing the inclined slider two to slide into the lock block. After the hole block passes, the inclined slider two immediately springs into the hole block, so that when the main unit is used in public places, it prevents the cover from being opened without authorization and blocks the possibility of illegally opening the cover by pushing, pulling and other conventional actions. Even when subjected to external force, the cover remains firmly locked to the outer shell, thereby achieving anti-theft protection for the inside of the equipment.

[0019] (6) In this invention, after the cover is locked, when the T-shaped rod is pushed in a certain distance and then rotated, the T-shaped rod will drive the push rod two to rise. The rise of the push rod two will push the inclined slider to slide towards the hole block. The inclined slider slides towards the hole block and pushes out the inclined slider two. At this time, the cover can be opened normally. When the T-shaped rod is pushed in and then rotated immediately, the rotation of the T-shaped rod will drive the pin to slide into the locking block. The pin will lock the inclined slider two and lock the cover, making the cover unable to be opened. At the same time, the T-shaped rod will also drive the T-shaped plate to move, releasing the limit on the elastic telescopic rod three, causing the extension end of the elastic telescopic rod three to pop out. The extension end of the elastic telescopic rod three will drive the right-angle block to fix the mounting bracket and the motherboard installed on the mounting bracket, so that even if the chassis is stolen, the cover cannot be easily opened. Even if the cover is forcibly opened, the more valuable motherboard cannot be removed without damaging the motherboard. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-10A computer case for easy motherboard installation includes a base 1, a shell 2 fixedly connected to the top of the base 1, a cover plate 3 rotatably connected to the front of the shell 2, a fixing post 4 rotatably connected to the inner wall of the shell 2, a push plate 5 and a mounting bracket 6 slidingly passing through the circumferential surface of the fixing post 4, a first spring 7 provided between the push plate 5 and the mounting bracket 6, and a door opening and fixing device provided on the outer wall of the shell 2, the door opening and fixing device including a fixing plate 801, a fixing cylinder 802, a fixing block 803 and a round bolt 804, the fixing plate 801 being fixedly connected to the side of the cover plate 3 away from the shell 2, the fixing cylinder 802 being fixedly connected to the upper surface of the fixing plate 801, the fixing block 803 being fixedly connected to the left side of the shell 2 near the fixing plate 801, and the round bolt 804 slidingly passing through the upper and lower surfaces of the fixing block 803, and a portable installation device provided inside the shell 2, the portable installation device including an arc block 901, an arc plate 902, a blocking block 903, a second blocking block 904, a wedge block 905, a push rod 906, and an L-shaped rod 907. The second push plate 908 and the arc block 901 are fixedly connected to the side of the cover plate 3 near the fixed post 4. The arc plate 902 slides through the end of the arc block 901 away from the cover plate 3. The blocking block 903 slides through the side of the arc block 901 away from the mounting bracket 6. A groove is opened on the left side of the arc plate 902. The blocking block 903 contacts the groove on the arc plate 902. The second blocking block 904 is fixedly connected to the bottom of the inner wall of the outer shell 2. The inclined block 905 slides through the top surface of the second blocking block 904. The inclined block 905 is close to the side of the outer shell 2. The cover has a sloping surface. The push rod 906 slides through the inner and outer walls of the outer casing 2. The L-shaped rod 907 is slidably connected to the bottom of the inner wall of the outer casing 2 and is rotatably connected to the arc plate 902. The second push plate 908 is fixedly connected to the end of the L-shaped rod 907 away from the arc plate 902. When the cover 3 is opened, the mounting bracket 6 will be pushed out through the arc block 901 and the second push plate 908, making it easier to install the computer motherboard on the mounting bracket 6 and avoiding the inconvenience of installing the motherboard in the small chassis.

[0024] A second spring is provided at the connection between the round bolt 804 and the fixing block 803. The second spring resets the round bolt 804. The arc plate 902 has a groove that contacts the blocking block 903. The blocking block 903 has an arc-shaped groove that can be driven to disengage from the groove of the arc plate 902 when it contacts the second blocking block 904. A third spring is provided between the second blocking block 904 and the inclined block 905. The third spring resets the inclined block 905.

[0025] The casing 2 is equipped with an anti-damage device, which includes a third stop block 101, a second inclined block 102, a telescopic rod 103, and a third inclined block 104. The third stop block 101 is fixedly connected to the side of the push plate 5 near the mounting bracket 6. The second inclined block 102 is slidably connected to the side of the mounting bracket 6 near the push plate 5. The telescopic rod 103 is fixedly connected to the bottom of the second inclined block 102. The third inclined block 104 is fixedly connected to the bottom of the inner wall of the casing 2. The arc block 901 and the arc plate 902 inside the arc block 901 are not restricted by the stop block 903 and can extend and retract, so that the cover 3 will not pull out the mounting bracket 6 when it is opened, preventing the mounting bracket 6 from being accidentally pulled out and colliding with the motherboard and other computer components installed on the motherboard.

[0026] The anti-damage device also includes a pressure plate 105, a second arc plate 106, a second arc block 107, a stop block 108, and a pressure rod 109. The pressure plate 105 is fixedly connected to the circumferential surface of the fixed end of the telescopic rod 103. The second arc plate 106 is fixedly connected to the end of the pressure plate 105 away from the telescopic rod 103. The second arc block 107 is fixedly connected to the side of the cover plate 3 near the fixed post 4. The second arc plate 106 slides through the interior of the second arc block 107. The stop block 108 is fixedly connected to the arc surface of the second arc block 107 near the push rod 906. One end of the pressure rod 109 is rotatably connected to the top of the stop block 903. The other end of the pressure rod 109, which is close to the second arc block 107, contacts the stop block 108. The push plate 5 drives the third stop block 101 to squeeze the second inclined block 102, causing the second inclined block 102 to slide downward. The second inclined block 102 pushes the telescopic rod 103 down. The telescopic rod 103 descends and stops the third inclined block 104, preventing the cover plate 3 from being opened. This alerts the operator that there is a foreign object blocking the front of the mounting bracket 6, preventing the operator from being careless and damaging the motherboard and other computer components.

[0027] A No. 4 spring is installed between the inclined block 2 102 and the mounting bracket 6. The No. 4 spring allows the inclined block 2 102 to return to its original position after sliding down.

[0028] The outer casing 2 is equipped with an anti-theft device, which includes a hole block 111, a sliding block 112, a T-shaped rod 113, a second push rod 114, a locking block 115, a pin 116, and a second sliding block 117. The hole block 111 is fixedly connected to the side of the cover plate 3 near the fixing post 4. The sliding block 112 is slidably connected to the right side of the inner wall of the hole block 111. The T-shaped rod 113 penetrates the inner and outer walls of the right side of the outer casing 2. The second push rod 114 is fixedly connected to the end of the T-shaped rod 113 that penetrates the interior of the outer casing 2. The locking block 115 is fixedly connected to the inner wall of the outer casing 2 near the T-shaped rod 113. The pin 116 slides through the inner and outer surfaces of the locking block 115, and the second inclined slider 117 slides through the left side of the locking block 115. A spiral spring is provided at the connection between the T-shaped rod 113 and the outer casing 2. The hole block 111 strikes the second inclined slider 117, causing the second inclined slider 117 to slide into the locking block 115. After the hole block 111 passes, the second inclined slider 117 immediately springs into the hole block 111, making it impossible for the cover plate 3 to be opened by pushing, pulling or other conventional actions. Even when subjected to external force, the cover plate 3 remains firmly locked to the outer casing 2, thereby achieving anti-theft protection for the inside of the equipment.

[0029] The anti-theft device also includes a telescopic rod 121, a strip plate 122, a T-shaped plate 123, a long plate 124, a fixed rod 125, an elastic telescopic rod 126, and a right-angle block 127. The telescopic rod 121 is fixedly connected to the bottom of the inner wall of the outer casing 2. The strip plate 122 is fixedly connected to the free end of the telescopic rod 121. The T-shaped plate 123 is slidably connected to the inner wall of the outer casing 2 near the T-shaped rod 123. A No. 6 spring is installed between the T-shaped plate 123 and the outer casing 2. The long plate 124 is fixedly connected to the end of the T-shaped plate 123 away from the inner wall of the outer casing 2. The fixed rod 125... 5 is fixedly connected to the bottom of the long plate 124. The elastic telescopic rod 3 126 is fixedly connected to the inner wall of the right side of the outer shell 2. The telescopic end of the elastic telescopic rod 3 126 has a groove and contacts the long plate 124. The right angle block 127 is fixedly connected to the top of the telescopic end of the elastic telescopic rod 3 126. The extended end of the elastic telescopic rod 3 126 drives the right angle block 127 to fix the mounting bracket 6 and the motherboard mounted on the mounting bracket 6. This makes it impossible to easily open the cover 3 after the chassis is stolen. Even if the cover 3 is forcibly opened, the more valuable motherboard cannot be removed without damaging the motherboard.

[0030] A No. 5 spring is provided between the locking block 115 and the inclined slider 117. The No. 5 spring allows the inclined slider 117 to return to its original position after sliding.

[0031] During operation, push the push rod 906, which pushes the stop block 903, causing it to slide into the grooves of the arc block 901 and the arc plate 902. The stop block 903 locks the arc block 901 and the arc plate 902 in place. Then, pull the cover plate 3, which rotates around the left side near the fixed block 803 to open. The cover plate 3 drives the arc block 901 to move synchronously, which in turn drives the L-shaped rod 907 to move. The L-shaped rod 907 then drives the second push plate 908 to move, which in turn pulls the push plate 5 towards the cover plate 3. Plate 5 moves the mounting bracket 6 toward the cover plate 3 via spring 7, thus pushing the mounting bracket 6 out and making it easier to install the computer motherboard on the mounting bracket 6. At the same time, the fixing cylinder 802 on the outer surface of the cover plate 3 strikes the round bolt 804, causing the round bolt 804 to slide upward. When the fixing cylinder 802 moves below the center of the round bolt 804, since there is nothing blocking it, the round bolt 804 resets and falls under the action of spring 2. This allows the cover plate 3 to be fixed in position after it is opened, preventing it from rotating randomly and facilitating the installation of the motherboard.

[0032] When the cover plate 3 is opened without the mounting bracket 6 being slid out, the stop block 903 is inserted into the arc plate 902 while the cover plate 3 is closed. During the reset process, the stop block 903 will hit the second stop block 904. Since the stop block 903 has an arc groove, the stop block 903 slides out of the groove in the arc plate 902. Therefore, the push rod 906 is not pushed before the cover plate 3 is opened. When the cover plate 3 is pulled, the arc block 901 moves accordingly, and the arc plate 902 slides out from inside the arc block 901, so the second push plate 908 cannot be pushed. In this way, the mounting bracket 6 cannot slide out, so that the cover plate 3 will not pull out the mounting bracket 6 when it is opened. This allows the operator to freely control whether the cover plate 3 is opened or not, so that the mounting bracket 6 can pop out.

[0033] When a component on the mounting bracket 6 is obstructed by the chassis, and the cover plate 3 is opened by mistakenly pushing in the stop block 903, the second push plate 908 causes the stop block 3 101 on the push plate 5 to press against the inclined block 2 102 on the mounting bracket 6. This causes the inclined block 2 102 to slide downwards, which in turn causes the telescopic rod 103 to descend. The descending telescopic rod 103 then blocks the inclined block 3 104, preventing the mounting bracket 6 from moving towards the cover plate 3. This serves as a reminder to the operator that there is a foreign object obstructing the mounting bracket 6; please remove it promptly to avoid further disruption to the work. Personnel negligence caused damage to the motherboard and other computer components. At the same time, when the telescopic rod 103 descended and pressed against the inclined block 104, the telescopic rod 103 descended and simultaneously drove the pressure plate 105 down. The pressure plate 105 pressed down and drove the arc plate 106 down. The arc plate 106 pressed down and drove the stop block 108 down. The stop block 108 pressed down and pressed the pressure rod 109. The pressure rod 109 caused the blocking block 903 to slide out of the groove of the arc plate 902, releasing the limit on the arc plate 902, so that the cover plate 3 could be opened normally to clean the foreign objects blocking the movement of the mounting bracket 6.

[0034] When the cover 3 is about to close, the hole block 111 strikes the inclined slider 117, causing the inclined slider 117 to slide into the locking block 115. After the hole block 111 passes, the inclined slider 117 immediately springs into the hole block 111, preventing the cover 3 from being opened by pushing or pulling. This avoids the operator accidentally opening the cover 3, which could damage the internal working parts and computer components of the chassis.

[0035] After cover plate 3 is locked, when the T-shaped rod 113 is pushed in a certain distance and then rotated, the T-shaped rod 113 will drive the strip plate 122 to rise through the telescopic rod 121. The rise of the strip plate 122 will push the inclined slider 112 to slide towards the hole block 111. The inclined slider 112 sliding towards the hole block 111 pushes out the inclined slider 117. At this time, cover plate 3 can be opened normally. When the T-shaped rod 113 is pushed in and then immediately rotated, the rotation of the T-shaped rod 113 will drive the pin 116 to slide into the locking block 115. The pin 116 will lock the inclined slider 117, preventing the inclined slider 117 from sliding towards the hole block 111 through the inclined slider 112. Pushing the inclined slider 117 retracts into the locking block 115, releasing the restriction on the cover plate 3, thus locking the cover plate 3 and preventing it from being opened. At the same time, the rotation of the T-shaped rod 113 in the same position will also drive the T-shaped plate 123 to slide deeper into the chassis, releasing the restriction on the elastic telescopic rod 126, causing the extension end of the elastic telescopic rod 126 to pop out. The extension end of the elastic telescopic rod 126 drives the right-angle block 127 to firmly fix the mounting bracket 6 and the motherboard mounted on the mounting bracket 6, so that even if the chassis is stolen, the cover plate 3 cannot be easily opened, and even if the cover plate 3 is forcibly opened, the more valuable motherboard cannot be removed without damaging the motherboard.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
