TECHNICAL FIELD

[0001] The present application relates to the technical field of computer backpacks, in particular to a high-ventilation computer backpack with adjustable anti-impact strength. BACKGROUND

[0002] As a kind of backpack specially used for carrying and protecting notebook computers, computer backpacks have been widely used in people's daily work, study and travel, and in order to meet the needs of different users, computer backpacks are increasingly diversified in material, capacity, appearance design and functionality.

[0003] With the increasing popularity and precision of electronic devices such as notebook computers, their value is also increasing, and users pay more attention to the safety of these devices during movement. Although traditional computer backpacks provide basic accommodation functions, their anti-impact and anti-falling performance is limited. Once the backpack is accidentally dropped or collided, the valuable electronic devices inside are easily damaged. At the same time, users are prone to accumulate heat and sweat on their backs when carrying a computer backpack for a long time, resulting in stuffiness and discomfort, especially in hot weather or long walks. Therefore, there is an urgent need for a high-ventilation computer backpack that can provide effective anti-impact protection and ensure air circulation and comfortable feeling on the back when carrying.

[0004] Currently, in order to solve the above problems, some computer backpacks with both anti-impact and high ventilation have appeared in the prior art. They mainly fill high-ventilation sponges around the computer layer, use thick and heavy padding on the outside and bottom, and use large-mesh fabric, so as to balance the ventilation while providing anti-impact protection. However, the anti-impact strength of the computer backpack in the prior art is usually fixed and cannot be adjusted by the user according to actual needs, which makes the backpack look heavy when it does not need high-strength protection, and the protection force is insufficient when it is needed. Moreover, the high-strength anti-impact structure often increases the overall weight and volume of the backpack, reducing the practicality of the computer backpack. SUMMARY

[0016] This invention provides a highly breathable laptop backpack with adjustable impact resistance. It offers the following advantages: 1. This invention uses sandwich mesh fabric to make the back layer of the computer bag, which improves the breathability of the computer bag and the user's back. By pressing the inflation ball, air is inflated into the air bladder through the air tube, causing the air bladder to expand and provide impact protection for the computer bag. The air pressure pushes the piston upward, causing the movable rod to extend out of the tube. By controlling the extension length of the movable rod, the volume of the mounting layer and the impact resistance provided can be adjusted, thus improving the practicality of the computer backpack.

[0017] 2. This invention pushes a power bank or other items into a hollow plate, and a spring pushes the L-shaped plate to move, causing the power bank to engage and be fixed inside the hollow plate. This makes it convenient for staff to use. Furthermore, the computer bag is in contact with the ground through the hollow plate, allowing it to be placed on the ground without easily tipping over and preventing wear and tear from friction with the ground, thus improving the convenience of the computer bag.

[0018] 3. This invention uses an upward-pulling hollow block to rotate the movable frame via a connecting rod, causing the pressure plate to press against the computer and fix it in place. A torsion spring drives the disc to rotate, and the curved groove pushes the insertion post to move, causing the latch to engage in the slot, thus fixing the position of the outer shell and the hollow block. This prevents the pressure plate from loosening and ensures that the computer remains fixed on the bracket during use of the computer backpack, preventing it from shaking.

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.

[0022] Reference Figure 1 , Figure 3 and Figure 4This invention provides a highly breathable computer backpack with adjustable impact resistance, including a computer bag 1. An installation layer 5 is sewn onto the outer side of the computer bag 1, and a protective mechanism 2 is provided on the inner side of the installation layer 5. The protective mechanism 2 is used to provide impact protection for the computer bag. A placement mechanism 3 is provided at the bottom of the computer bag 1. The placement mechanism 3 is used to place items while improving the wear resistance of the bottom of the computer bag. A fixing mechanism 4 is provided on the inner side of the computer bag 1. The fixing mechanism 4 is used to fix the computer. The protective mechanism 2 includes an airbag 21, which is fixedly connected to the inner side of the mounting layer 5. An air tube 22 is connected to the top of the airbag 21, and an inflatable ball 23 is connected to the left end of the air tube 22. The inflatable ball 23 can inflate the airbag 21 with gas through the air tube 22. A tube 24 is connected to the top right side of the airbag 21, and a piston 25 is slidably connected to the inner side of the tube 24. A movable rod 26 is fixedly connected to the top of the piston 25. When the internal air pressure of the airbag 21 increases, it pushes the piston 25 upward, thereby causing the movable rod 26 to move upward. A spring 27 is provided on the outer side of the movable rod 26, and the top of the spring 27 is fixedly connected to the tube 24. The spring 27 can push the piston 25 downward. The top of the movable rod 26 penetrates the tube 24, and a scale 28 is provided on the front side of the movable rod 26 for easy observation. The piston 25 has an extension length, and a sealing ring 29 is fixedly connected to the bottom of the piston 25. The sealing ring 29 can improve the sealing performance of the piston 25. The protective mechanism 2 also includes a one-way valve 215, which is located on the outside of the air tube 22. A storage compartment 214 is fixedly connected to the top of the left end of the inner side of the mounting layer 5. The inflatable ball 23 is placed inside the storage compartment 214. The storage compartment 214 can prevent the inflatable ball 23 from being squeezed. The protective mechanism 2 also includes a transparent shell 210, which is fixedly connected to the top of the tube body 24. An observation port 211 is provided on the top of the front side of the mounting layer 5. The protective mechanism 2 also includes an air outlet 212, which is connected to the top left side of the airbag 21. An air outlet cap 213 is threadedly connected to the top of the air outlet 212. Opening the air outlet cap 213 allows the gas in the airbag 21 to be released through the air outlet 212. Specifically, the back of the laptop bag 1 is made of sandwich mesh fabric, which improves breathability to the user's back when carrying it. When in use, the laptop is placed in the laptop bag 1, and the inflation ball 23 is pressed. Gas enters the airbag 21 through the air tube 22, causing the airbag 21 to inflate and provide impact protection for the laptop bag 1. When the airbag 21 inflates, the internal air pressure increases, pushing the piston 25 in the tube 24 to move upward. The piston 25 drives the movable rod 26 to move upward and squeeze the spring 27. The scale 28 on the front of the movable rod 26 is used to observe its extension length to control the internal air pressure of the airbag 21. Controlling the inflation pressure of the airbag 21 adjusts the volume and impact resistance of the mounting layer 5, and prevents gas leakage from the inside of the airbag 21 through the sealing ring 29.

[0023] ReferenceFigure 1 , Figure 2 and Figure 5 The placement mechanism 3 includes a hollow plate 31, which is fixedly connected to the bottom of the computer bag 1. Fixing rods 32 are fixedly connected to the left and right sides of the interior of the hollow plate 31. An L-shaped plate 33 is slidably connected to the outer side of the fixing rods 32. A second spring 34 is provided on the outer wall of the fixing rods 32, and the second spring 34 contacts the L-shaped plate 33, pushing the L-shaped plate 33 to move. A latch 35 is fixedly connected to one side of the L-shaped plate 33, and the L-shaped plate 33 moves the latch 35 to secure a power bank or other items. A guide rod 36 is fixedly connected to the rear interior of the computer bag 1. Inclined plates 37 are slidably connected to the left and right sides of the outer wall of the guide rod 36. Springs 38 are provided at the left and right ends of the outer wall of the guide rod 36, contacting the inclined plates 37, and pushing the inclined plates 37 to move. The plate 37 moves, and the front side of the two inclined plates 37 is provided with the same push plate 39. The inclined plates 37 will push the push plate 39 to move forward. The placement mechanism 3 also includes a guide groove 310. The two guide grooves 310 are respectively opened on the left and right sides of the interior of the hollow plate 31. The outer side of the push plate 39 is slidably connected to the guide groove 310. The push plate 39 will slide inside the guide groove 310. The placement mechanism 3 also includes a lever 311. The lever 311 is fixedly connected to the front side of the L-shaped plate 33. The left and right sides of the front wall of the hollow plate 31 are provided with through grooves 312. The front side of the lever 311 passes through the through grooves 312. Moving the lever 311 can drive the L-shaped plate 33 to move. One end of the fixing rod 32 is fixedly connected to a limit piece 313. The limit piece 313 can prevent the L-shaped plate 33 from falling out of the fixing rod 32. Specifically, when the laptop backpack is placed on the ground, the laptop bag 1 contacts the ground through the hollow plate 31, keeping the laptop bag 1 stable and preventing it from falling over and being worn. The power bank is pushed into the hollow plate 31, and the second spring 34 pushes the L-shaped plate 33 to move, so that the locking block 35 engages with the power bank, fixing the power bank inside the hollow plate 31. When removing the power bank, the levers 311 on both sides are moved. The levers 311 drive the L-shaped plate 33 to move, so that the locking block 35 disengages from the power bank. At this time, the third spring 38 pushes the inclined plate 37 to slide on the guide rod 36, pushing the push plate 39 forward to push the power bank out.

[0024] Reference Figure 6 , Figure 7 and Figure 8The fixing mechanism 4 includes a back plate 41, which is fixedly connected to the rear interior of the computer bag 1. A bracket 42 is fixedly connected to the bottom front side of the back plate 41 to support the computer. A movable frame 43 is rotatably connected to the front side of the bracket 42. Pressure plates 44 are rotatably connected to the left and right sides of the rear wall of the movable frame 43. Rotation of the movable frame 43 will cause the pressure plates 44 to press against the computer. A connecting rod 45 is rotatably connected to the left and right sides of the movable frame 43. Slide grooves 46 are provided on both the left and right sides of the computer bag 1. The sliding groove 46 has slots 47 on both its front and rear sides. A housing 48 is slidably connected to the inner side of the sliding groove 46. A latch 410 is provided on both the left and right sides of the inner side of the housing 48. The outer side of the latch 410 penetrates the housing 48 and engages with the slots 47, thus fixing the position of the housing 48. A control component 49 is provided on one side of the housing 48. The control component 49 includes a hollow block 491, which is fixedly connected to one side of the housing 48. The interior of the hollow block 491 rotates... A rotating rod 498 is connected to the rotating rod 498. One end of the rotating rod 498 is fixedly connected to a disc 492. Curved grooves 493 are provided on the front and rear sides of the outer wall of the disc 492. A plug-in post 494 is slidably connected to the inner side of the curved groove 493. The disc 492 can push the plug-in post 494 to move through the curved groove 493. A limiting groove 495 is provided on the outer side of the hollow block 491. The plug-in post 494 passes through the limiting groove 495 and is fixedly connected to the latch 410. A torsion bar is provided on the outer side of the rotating rod 498. The two ends of the force spring 496 and the torsion spring 496 are fixedly connected to the disc 492 and the hollow block 491 respectively. The torsion spring 496 can drive the disc 492 to rotate. The other end of the rotating rod 498 passes through the hollow block 491 and is fixedly connected to the knob 497. The knob 497 can drive the rotating rod 498 to rotate, thereby driving the disc 492 to rotate. The rear side of the connecting rod 45 is rotatably connected to the hollow block 491. The hollow block 491 can pull the movable frame 43 to rotate through the connecting rod 45. Specifically, when placing the computer into the computer bag 1, first place the computer on the bracket 42, then pull up the hollow blocks 491 on both sides. The hollow blocks 491 pull the movable frame 43 to rotate through the connecting rod 45, causing the pressure plate 44 to press against the computer. At the same time, the hollow blocks 491 move the outer shell 48, causing the latches 410 to move accordingly. When the pressure plate 44 presses the computer tightly, the torsion spring 496 drives the disc 492 to rotate. The disc 492 pushes the plug pin 494 to move through the curved groove 493, causing the latches 410 on both sides to engage in the slots 47, fixing the position of the outer shell 48 and the hollow blocks 491, preventing the pressure plate 44 from loosening. When removing the computer, rotate the knob 497. The knob 497 drives the disc 492 to rotate in the opposite direction through the rotating rod 498, causing the pressure plate 44 to disengage from the computer, and the computer can then be removed.

[0025] Reference Figure 1 and Figure 2 The top of the computer bag 1 is equipped with a zipper 6, and the top of the mounting layer 5 is equipped with a zipper 7. Specifically, the computer bag 1 and the installation layer 5 can be opened more conveniently through zipper 6 and zipper 7.

[0026] Working principle: The back of the computer bag 1 is made of sandwich mesh fabric, which improves the breathability of the computer bag 1 and the user's back when the computer bag 1 is carried. When using the computer bag, the computer is placed in the computer bag 1 and the inflation ball 23 is pressed. The inflation ball 23 inflates the air bladder 21 through the air tube 22, causing the air bladder 21 to expand and thus provide impact protection for the computer bag 1. When the air bladder 21 expands, the air pressure inside the air bladder 21 will increase. The air pressure will push the piston 25 inside the tube 24 to move upward. The piston 25 will then drive the movable rod 26 to move upward and squeeze the spring 27. The extension length of the movable rod 26 can be accurately observed through the scale 28 on the front of the movable rod 26, and the air pressure inside the air bladder 21 can be controlled. By controlling the inflation pressure of the air bladder 21, the volume and impact resistance of the mounting layer 5 can be adjusted. The sealing ring 29 can prevent the gas inside the air bladder 21 from leaking. Furthermore, when the computer backpack is placed on the ground, the computer bag 1 contacts the ground through the hollow plate 31, ensuring the computer backpack remains stable and does not easily tip over, thus preventing wear and tear caused by the computer bag 1 contacting the ground. When in use, pushing a power bank or other items into the hollow plate 31 will cause the spring 2 34 to push the L-shaped plate 33 to move, allowing the latch 35 to engage with the power bank, thereby fixing the power bank inside the hollow plate 31 for easy use by staff. When it is necessary to remove the power bank, moving the levers 311 on both sides will cause the levers 311 to move the L-shaped plate 33 in a certain direction, while the latch 35 disengages from the power bank. The spring 38 will then push the inclined plate 37 to slide on the guide rod 36, thereby pushing the push plate 39 forward to push the power bank forward for easy use by the user. Finally, when placing the computer in the computer bag 1, first place the computer on the bracket 42, then pull up the hollow blocks 491 on both sides. The hollow blocks 491 will pull the movable frame 43 to rotate through the connecting rod 45, thereby causing the pressure plate 44 to press against the computer. The hollow blocks 491 will also move the outer shell 48, thereby moving the latches 410. When the pressure plate 44 presses the computer, the torsion spring 496 will drive the disc 492 to rotate. When the disc 492 rotates, it can push the plug pin 494 to move through the curved groove 493, thereby causing the latches 410 on both sides to engage in the slots 47, fixing the position of the outer shell 48 and the hollow blocks 491, so that the pressure plate 44 will not loosen. When it is necessary to remove the computer, rotate the knob 497. The knob 497 can drive the disc 492 to rotate in the opposite direction through the rotating rod 498, so that the pressure plate 44 can be released from the computer, and the computer can be easily removed.
