Description

Technical Field

[0001] This utility model relates to the field of laptop bags, and more particularly to a laptop backpack with an integrated quick-release multi-directional adjustable stand. Background Technology

[0002] With the development of wireless network technology, cloud computing, battery technology, and computer chip technology, image display devices are trending towards miniaturization and lightweight design. The frequency of use of thin and light laptops, tablets with keyboards (such as foldable tablets with magnetic keyboards or keyboard cases), e-readers, smartphones, and portable information terminals is increasing both indoors and outdoors. Existing laptop bags are primarily used for carrying and protecting laptops, lacking the function of supporting work. Some bags, laptop stands, or small tables that do offer support require a work surface and are not suitable for outdoor use. Therefore, current technology cannot meet the need for both safe carrying and convenient use of laptops in various scenarios.

[0003] Chinese patent CN218105144U discloses a laptop bag with a stand, comprising a first body and a second body rotatably connected together. The first body has a laptop storage bag and a tablet storage bag. A first-type stand is located on the back of the first body, providing both storage and support for a tablet, thus expanding the functionality of the laptop bag and providing convenience for the user. However, the existing technology still has the following drawbacks: existing laptop bags with stands still require a table for support during use, but situations often arise where no table is available, rendering the laptop bag unusable. Therefore, there is a need for a laptop backpack with multiple adjustable styles and a built-in portable worktable to meet the needs of different usage scenarios. Utility Model Content

[0004] The technical problem to be solved by this utility model is: in order to solve the problem that existing laptop backpacks cannot meet the needs of different usage scenarios, this utility model provides a laptop backpack with an integrated quick-release multi-directional adjustable bracket that can be transformed into various styles.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a computer backpack with an integrated quick-release multi-directional adjustable bracket, including a backpack and a computer bracket. The backpack includes a zippered pouch for storing items and a shoulder strap cover for carrying. The computer bracket includes a load-bearing component for carrying items, a cantilever connecting rod for connecting, and a support base for supporting. The shoulder strap cover covers the support base to form a carrying device with carrying and support functions. The cantilever connecting rod is provided with two or more rotating mechanisms, each of which has the function of adjusting the angle and positioning. The two ends of the cantilever connecting rod are respectively connected to the load-bearing component and the support base through the rotating mechanisms, so that it can be rotated and positioned to different angles on the same side of the cantilever connecting rod, thereby adapting to use in different scenarios.

[0006] Furthermore, the cantilever connecting rod includes a first rotating mechanism, a second rotating mechanism, a third rotating mechanism, a vertical rod, and a horizontal rod. The upper and lower ends of the vertical rod are respectively connected to the fixed ends of the second rotating mechanism and the first rotating mechanism. The axes of the first rotating mechanism and the second rotating mechanism are aligned and perpendicular to the vertical rod. One end of the horizontal rod is connected to the rotating shaft of the second rotating mechanism, and the other end is connected to the fixed end of the third rotating mechanism. The axis of the third rotating mechanism is perpendicular to the horizontal rod. Through the connection of the horizontal rod and the vertical rod with multiple rotating mechanisms, the tilt angle of the zipper bag can be adjusted freely, and the relative position of the zipper bag and the carrying device can also be adjusted, which can adapt to different usage scenarios and facilitate users to adjust according to their own usage habits.

[0007] Furthermore, the first, second, and third rotating mechanisms all have a fixed end at one end and a rotating shaft with a positioning and limiting device at the other end. The fixed end can rotate 360° around the shaft. The object connected to the rotating shaft is perpendicular to the rotating surface. The positioning and limiting device adopts a bidirectional ratchet mechanism. The bidirectional ratchet mechanism plays the role of adjusting the angle in multiple positions and limiting the rotation of the shaft in one direction. When the paddle of the bidirectional ratchet is moved to the other side, the direction that can be rotated is blocked, and it can only rotate in the opposite direction. When the direction of the eccentric gravity is consistent with the blocked direction, then this direction is locked and positioned, and it can be rotated and adjusted in the opposite direction. The smallest scale of the bidirectional ratchet mechanism is the smallest adjustable position it can adjust.

[0008] Furthermore, the rotating shaft is provided with a quick-release mechanism, which may include, but is not limited to, a sliding ball-locking structure, that is, a press-type ball-locking structure and an annular groove interlocking structure, so that it can be adjusted to the required shape more quickly. Conventional mechanical quick-release devices in the art, such as cam locking structures, may also be used.

[0009] Furthermore, the support base is formed by connecting the front rod, side rod and rear rod in sequence to form an inverted U-shaped frame. The side rod is close to and parallel to the vertical rod, and the rear rod is connected to the rotation axis of the first rotating mechanism. The connection method of the rods of the support base includes, but is not limited to, welding, pipe connection or integral molding.

[0010] Furthermore, the shoulder strap cover is integrated with the support base, and the connection method includes, but is not limited to, sewing, insertion, snap, and overlapping; the shoulder strap cover is provided with at least one longitudinal shoulder strap and at least one transverse shoulder strap, as well as a detachable connection structure integrated with the bottom of the zipper surface.

[0011] Furthermore, the zippered bag is a three-sided zippered bag consisting of an upper zipper side and a lower zipper side; the top two corners of the upper zipper side are provided with strip-shaped straps to hold the display screen; the lower part of the lower zipper side has an opening below the zipper in the middle to facilitate the connection between the carrying component and the third rotating mechanism; the lower part of the lower zipper side has a pocket to prevent internal objects from slipping out; the back of the lower zipper side has a storage pocket for storing items; and the bottom of the lower zipper side has a detachable connection structure that connects the zippered bag and the carrying device as one unit. The detachable connection structure includes, but is not limited to, magnetic connection, buckle connection, hook connection, lock connection, or adhesive connection.

[0012] Furthermore, the carrying component is placed inside the lower zipper surface of the zipper bag and is integrated with it. The connection method includes, but is not limited to, riveting, screwing, gluing, hanging, and buckling. The carrying component consists of a panel and a connecting rod located on one side of the bottom of the panel and parallel to that side. The panel is, but is not limited to, a square panel, which serves as a carrier. One end of the connecting rod is connected to the third rotating mechanism through an opening extending from the lower zipper surface and is perpendicular to the crossbar.

[0013] Furthermore, the rod is a support rod with a hollow structure.

[0014] The beneficial effects of this utility model are:

[0015] The computer backpack with integrated quick-release multi-directional adjustable bracket described in this utility model connects the cantilever connecting rod, zipper bag, and carrying device through a rotating mechanism, allowing it to rotate freely and be positioned at different angles. When unfolded for use, it can be transformed into various styles of computer work platforms to adapt to corresponding scenarios. When not in use, it can be folded into a laptop backpack for easy carrying. Attached Figure Description

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; the rod is a support rod with a hollow structure. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] Example 1

[0036] like Figure 1-2As shown, a computer backpack with an integrated quick-release multi-directional adjustable bracket includes a backpack 1 and a computer stand 25. The backpack 1 includes a zippered pouch 19 for storing items and a shoulder strap cover 10 for carrying. The computer stand 25 includes a carrying component 18 for carrying items, a cantilever connecting rod 3 for connecting, and a support base 9 for supporting. The shoulder strap cover 10 covers the support base 9 to form a carrying device 2 with carrying and support functions. The cantilever connecting rod 3 is provided with two or more rotating mechanisms, each of which has the function of adjusting the angle and positioning. The two ends of the cantilever connecting rod 3 are respectively connected to the carrying component 18 and the support base 9 through the rotating mechanisms, so that it can be rotated and positioned to different angles on the same side of the cantilever connecting rod, thereby adapting to use in different scenarios.

[0037] like Figure 3 As shown, the cantilever connecting rod 3 includes a first rotating mechanism 4, a second rotating mechanism 5, a third rotating mechanism 6, a vertical rod 7, and a horizontal rod 8; the upper and lower ends of the vertical rod 7 are respectively connected to the fixed ends 41 of the second rotating mechanism 5 and the first rotating mechanism 4, and the axial directions of the first rotating mechanism 4 and the second rotating mechanism 5 are aligned and perpendicular to the vertical rod 7; one end of the horizontal rod 8 is connected to the rotating shaft 42 of the second rotating mechanism 5, and the other end is connected to the fixed end 41 of the third rotating mechanism 6, and the axial direction of the third rotating mechanism 6 is perpendicular to the horizontal rod 8.

[0038] like Figure 4 As shown, the horizontal bar 8 and the vertical bar 7 are connected to multiple rotating mechanisms, so that the tilt angle of the zipper bag 19 can be adjusted at will, and the relative position of the zipper bag 19 and the carrying device 2 can also be adjusted, which can adapt to different usage scenarios and make it convenient for users to adjust according to their own usage habits.

[0039] like Figure 5 As shown, the first rotating mechanism 4, the second rotating mechanism 5 and the third rotating mechanism 6 all have a fixed end 41 at one end and a rotating shaft 42 with a positioning and limiting device at the other end. The fixed end 41 can rotate 360° around the shaft, and the object connected to the rotating shaft 42 is perpendicular to the rotating surface.

[0040] like Figure 5As shown, the rotating shaft 42 with positioning and limiting device can adopt a bidirectional ratchet mechanism. The bidirectional ratchet mechanism mainly consists of a gear box 421, a gear shaft 422, a pawl 423, a reversing block 424, and a paddle 425. The gear shaft has a cylindrical cavity for integrating a sliding ball mechanism. The bidirectional ratchet mechanism plays the role of adjusting the angle in multiple positions and restricting the rotation of the shaft in one direction. When the paddle 425 of the bidirectional ratchet is moved to the other side, the reversing block 424 will push the pawl 423 to the other side to mesh with the gear shaft 422. The direction in which the gear shaft 422 can rotate is blocked, and it can only rotate in the opposite direction. From the outside, it looks like the fixed end 41 of the rotating mechanism cannot rotate. When the direction of the eccentric gravity is consistent with the blocked direction, then this direction is locked and positioned, and it can be rotated and adjusted in the opposite direction. The smallest scale of the bidirectional ratchet mechanism is the smallest adjustable position.

[0041] like Figure 6 As shown, the rotating shaft 42 is equipped with a quick disassembly mechanism. The quick disassembly mechanism adopts a sliding groove type locking bead structure, that is, a press-type locking bead and an annular groove interlocking structure, which allows it to be adjusted to the required shape more quickly. In use, the combination of the zipper bag 19 and the carrying component 18 can be separated from the main body through the third rotating mechanism 6. The remaining main body is adjusted to a suitable shape, and then the combination of the zipper bag 19 and the carrying component 18 can be connected into one piece through the third rotating mechanism 6.

[0042] like Figure 7 As shown, the sliding ball retaining mechanism mainly consists of a button post 27, a return spring 28, and a retaining ball 29. The cylindrical cavity of the gear shaft 422 is basically matched with the button post with the spring. By pressing and releasing the button post 27, the retaining ball 29 is embedded in the annular groove in the sleeve 30 to form a mechanical interlock. Pressing the button post 27 causes the retaining ball 29 to disengage from the annular groove in the sleeve 30, and the bidirectional ratchet mechanism disengages from the sleeve 30, realizing quick disassembly. The other end of the sleeve 30 is fitted onto the rod, and the rod and the sleeve 30 are fixed together by screws or other means.

[0043] like Figure 8 As shown, the supporting base 9 is formed by connecting the front rod 11, the side rod 13, and the rear rod 12 in sequence to form an inverted U-shaped frame. The front rod 11 and the rear rod 12 are located at both ends of the same side of the side rod 13 and are perpendicular to the side rod 13. The front rod 11 is connected to the side rod 13 through a double-through bend 14, and the rear rod 12 is connected to the side rod 13 through a three-way connector 15. The other end of the three-way connector 15 is connected to the first rotating mechanism 4. The shoulder strap cover 10 is integrated with the supporting base 9, and the connection method includes, but is not limited to, sewing. The shoulder strap cover 10 is provided with two longitudinal shoulder straps 16 and one transverse shoulder strap 17, as well as Velcro 23 integrated with the bottom of the zipper surface 192. The material of the shoulder strap cover 10 can be fabric, composite material, or other suitable material.

[0044] like Figure 9 As shown, the zippered bag 19 is a three-sided open zippered bag 19 consisting of an upper zipper surface 191 and a lower zipper surface 192; the upper zipper surface 191 has strip-shaped straps 26 at the top two corners to hold the display screen; the lower zipper surface 192 has an opening 24 below the zipper in the middle to facilitate the connection between the carrying component 18 and the third rotating mechanism 6; the lower part of the lower zipper surface 192 has a pocket 22 to prevent internal objects from slipping out; the lower zipper surface 192 has buckle strips 201 on three sides except for the pocket side; the head of the buckle strip 201 is spherical for connecting with holes of other objects; the other end of the buckle strip 201 is connected to the inner edge of the lower zipper surface 192; the back of the lower zipper surface 192 can be provided with a storage bag for storing items; the bottom of the lower zipper surface 192 has Velcro 23 to connect the zippered bag 19 and the carrying device 2 as one unit.

[0045] like Figure 9 As shown, the carrying component 18 is placed inside the zipper surface 192 of the zippered bag 19 and is integrated with it, and the connection method is a snap fastener; the carrying component 18 consists of a panel 20 and a connecting rod 21 located on one side of the bottom of the panel 20 and parallel to it. The panel 20 is, but is not limited to, a square panel 20. The three edges of the panel 20 have holes 202. The holes 202 are positioned so that the buckle strip can reach them. The shape of the holes is composed of a circle and a small rectangle. One end of the circle is closer to the inside, and the small rectangle is closer to the edge of the panel 20 and perpendicular to the edge. The head of the buckle strip 201 can pass through the circular hole, but not through the rectangular hole, so it is locked. A small cover 203 can be added to the circular hole. One end of the connecting rod 21 is connected to the third rotating mechanism 6 through the opening 24 extending out of the zipper surface 192 and is perpendicular to the crossbar 8; the carrying component and the carried object can be connected by, but not limited to, Velcro, to make the carried object more stable.

[0046] Example 2

[0047] In scenarios with chairs but no tables, when using it, such as Figure 10 As shown;

[0048] Place the carrying device 2 on a chair. Adjust the first rotating mechanism 4 to position the zippered bag 19 in front of the carrying device 2, and adjust it to a suitable height according to the user's height. Then, adjust the level of the zippered bag 19 using the second rotating mechanism 5 and the third rotating mechanism 6. At this time, the carrying surface of the zippered bag 19 faces upwards. The user sits on the carrying device 2, and the carrying device 2 is secured by the user's weight. The carrying device 2 supports the zippered bag 19 via the cantilevered connecting rod 3, placing it on or above the user's thighs, thus allowing the zippered bag 19 to be used as a work table. When the zippered bag 19 is on the user's thighs, it is more suitable for typing, as the support is more stable; when the zippered bag 19 is above the user's thighs, it is suitable for browsing the web and watching videos.

[0049] Example 3

[0050] In a setting with tables and chairs, when using it, such as Figure 11 As shown;

[0051] With the carrying device 2 placed on a table as a base, the zippered bag 19 is positioned above the carrying device 2 and adjusted to a suitable height using the first rotating mechanism 4. The front-to-back tilt of the zippered bag 19 is then adjusted using the second rotating mechanism 5, and the left-to-right tilt angle is adjusted using the third rotating mechanism 6. At this point, the carrying device 2, the zippered bag 19, and the cantilevered connecting rod 3 form a reverse Z-shape when viewed from the side. With the carrying surface of the zippered bag 19 facing upwards, a laptop is placed on the zippered bag 19 for use, thus forming a convenient laptop stand.

[0052] Example 4

[0053] In scenarios without tables or chairs, when using it, such as Figure 12 As shown;

[0054] The carrying device 2 is secured to the user's body via the shoulder strap cover 10 and the shoulder straps, with the side bar 13 located below and the rear bar 12 located on the right. The zippered bag 19 is then adjusted to be in front of the user and close to their waist and abdomen via the first and second rotating mechanisms 4 and 5 of the cantilevered connecting rod 3. Finally, the third rotating mechanism 6 is adjusted to make the zippered bag 19 form a worktable. At this point, with the carrying surface of the zippered bag 19 facing upwards and the laptop placed on it, a computer work platform for use in a scenario without a table or chair is created.

[0055] Example 5

[0056] When used as a backpack, such as Figure 13 As shown;

[0057] Close the zippered pouch 19, and adjust the carrying device 2 above the zippered pouch 19 using the rotating mechanism of the cantilever connecting rod 3, so that the zippered pouch 19, the vertical rod 7 of the cantilever connecting rod 3, and the carrying device 2 form a flattened Z-shape from the side; then fix the carrying device 2 and the zippered pouch 19 together using the detachable connecting device. At this point, a laptop backpack is formed, making it convenient for the user to carry.

[0058] Example 6

[0059] like Figure 14As shown, this embodiment provides a computer backpack with an integrated quick-release multi-directional adjustable bracket based on embodiment 1. Its structure is roughly the same as that of the computer backpack with an integrated quick-release multi-directional adjustable bracket disclosed in embodiment 1. The difference is that the quick-release mechanism of the rotating shaft adopts a cam locking structure. The cam locking mechanism is set on the gear shaft. The cam locking mechanism on the cam gear shaft 31 mainly consists of a handle 32 with a cam, an ear seat 33, and a pin 34. By rotating the handle, the cam is locked into the slot 35 of the connecting rod. If the quick-release function of this rotating shaft is not frequently used, the cam gear shaft and the sleeved rod can be fixed with screws.

[0061] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
