Description

Technical Field

[0001] This utility model relates to a computer bag. Background Technology

[0002] With the widespread adoption of mobile work and digital living, laptops have become essential tools for daily work and study. To better protect laptops and improve portability, laptop bags, as an important accessory, are constantly evolving in terms of functionality and structural design. Currently, the market offers a wide variety of laptop bags, with some high-end products integrating additional features such as folding stands and adjustable restraint structures on top of traditional storage functions.

[0003] Folding stands are typically located inside the bottom cover of a laptop bag, providing support when using the computer and allowing it to tilt at a certain angle, thereby improving heat dissipation and enhancing typing comfort. Adjustable restraint structures control the opening angle of the top cover, preventing it from flipping over excessively and encroaching on desk space.

[0004] However, the production of these multifunctional laptop bags presents significant technical bottlenecks. Since both the folding support and the restraining structure need to be sewn separately to the bottom cover of the laptop bag, and these two components are structurally and functionally independent, multiple steps are required on the production line for positioning, alignment, and sewing. In particular, ensuring smooth folding of the support and flexible adjustment of the restraining structure while simultaneously maintaining the strength of the stitching and a neat appearance further increases the complexity of the process.

[0005] Therefore, how to simplify the production process of computer bags while ensuring functional integrity has become an urgent technical problem to be solved in the current computer bag manufacturing industry. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a computer bag that is easy to manufacture.

[0007] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a computer bag, comprising: Top cover, the top cover is equipped with a first Velcro closure; The bottom cover is rotatably connected to the top cover, and the bottom cover is equipped with a second Velcro strap. The folding bracket includes a first part, a second part, and a third part connected in sequence. The first part and the third part are rotatable relative to the second part. The junction area between the first part and the second part is fixed to the bottom cover. The first part has a third hook and loop fastener that mates with a first hook and loop fastener, and the third part has a fourth hook and loop fastener that mates with a second hook and loop fastener.

[0008] Furthermore, the first part is a flexible component, while the second and third parts are rigid plates, respectively.

[0009] Furthermore, the junction area between the first part and the second part is bonded, welded, or sewn together with the bottom cover.

[0010] Furthermore, the inner surface of the top cover is velvet, and the first Velcro fastener is a portion of the inner surface of the top cover; or, the inner surface of the bottom cover is velvet, and the second Velcro fastener is a portion of the inner surface of the bottom cover.

[0011] Furthermore, the folding bracket is centered relative to the bottom cover.

[0012] Furthermore, the third Velcro strap is positioned away from the boundary area between the first and second parts.

[0013] Furthermore, the third part has an extension portion on the side away from the second part, and the fourth hook and loop fastener is disposed on the extension portion.

[0014] Furthermore, the extension portion is rotatable relative to other regions of the third portion.

[0015] Furthermore, the bottom cover has a receiving groove for accommodating the second and third parts.

[0016] Furthermore, the bottom cover is provided with corner bands at its two corners, and the corner bands are located away from the boundary area between the first part and the second part.

[0017] The beneficial effects of this utility model are as follows: This computer bag has a novel structure. The junction area between the first and second parts of the folding bracket is fixed to the bottom cover in one go. The third and fourth Velcro straps of the folding bracket are quickly bonded to the first Velcro strap of the top cover and the second Velcro strap of the bottom cover, respectively. This allows the bracket to be folded and stored at the same time, and the opening angle of the top cover to be limited. There is no need to set up a separate sewing position for the restraint structure. This simplifies the original multiple processes of positioning and sewing of the folding bracket and restraint structure into an integrated operation of "one-time sewing + Velcro bonding". It retains the original functions of the folding bracket in supporting heat dissipation and the top cover in preventing over-tipping, while significantly reducing the number of alignment and sewing times on the production line. It also reduces the need for repeated adjustments to the firmness and appearance consistency, achieving the beneficial effect of directly compressing process steps and facilitating mass production while maintaining complete functionality.

[0020] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0021] In known technologies, laptop bags are common accessories used to carry mobile office devices such as laptops and tablets. Besides their carrying and protection functions, laptop bags are becoming increasingly integrated and diversified. For example, when a suitable work surface is lacking, people often use laptop bags as temporary supports for their laptops or tablets. Typically, both the inner and outer surfaces of the top / bottom lid of a laptop bag can be used as support surfaces. To ensure that the screen of a laptop or tablet forms a comfortable viewing angle for the user, the introduction of a support stand that can hold it at a suitable angle has become a trend.

[0022] Please refer to Figures 1 to 6 The computer bag includes a top cover 1, a bottom cover 2, and a folding bracket 3. The top cover 1 is provided with a first Velcro 11. The bottom cover 2 is rotatably connected to the top cover 1 and is provided with a second Velcro 21. The folding bracket 3 includes a first part 31, a second part 32, and a third part 33 connected in sequence. The first part 31 and the third part 33 are rotatable relative to the second part 32. The junction area of ​​the first part 31 and the second part 32 is fixed on the bottom cover 2. The first part 31 has a third Velcro 5 that cooperates with the first Velcro 11, and the third part 33 has a fourth Velcro 6 that cooperates with the second Velcro 21.

[0023] The working principle of this computer bag is briefly described as follows: When in use, open the top cover 1, separate the first Velcro 11 and the third Velcro 5, and then continue to adjust the opening angle of the top cover 1. When it is rotated to a suitable angle, attach the third Velcro 5 on the first part 31 in the unfolded state to the first Velcro 11, so that the first part 31 applies a traction force to the top cover 1, thereby ensuring that the top cover 1 will not continue to flip outward under the action of gravity. Next, separate the second Velcro 21 and the fourth Velcro 6, and move the side of the third part 33 away from the first part 31 towards the direction closer to the top cover 1. At this time, the second part 32, the third part 33 and the bottom cover 2 form an approximately triangular structure. The height of this triangular structure directly affects the tilt angle of the computer placed on the folding bracket 3. After selecting the height of the triangular structure, attach the fourth Velcro 6 on the third part 33 to the second Velcro 21 to form a fixation. When part of the computer is placed on the top of the triangular structure, the computer is tilted and supported.

[0024] As can be seen from the above description, the beneficial effects of this utility model are as follows: This computer bag has a novel structure. The junction area of ​​the first part 31 and the second part 32 of the folding bracket 3 is fixed to the bottom cover 2 in one go. The third hook and loop fastener 5 and the fourth hook and loop fastener 6 of the folding bracket 3 are quickly bonded to the first hook and loop fastener 11 of the top cover 1 and the second hook and loop fastener 21 of the bottom cover 2, respectively. The folding and storage of the bracket and the opening and closing angle limitation of the top cover 1 can be completed at the same time. There is no need to set a separate sewing position for the binding structure. Thus, the folding bracket 3 and the binding structure, which originally required multiple processes for positioning and sewing, are simplified into an integrated operation of "one-time sewing + hook and loop fastener bonding". It retains the original functions of the folding bracket 3 for heat dissipation and the top cover 1 for preventing overturning. It also significantly reduces the number of alignment and sewing times on the production line and reduces the repeated adjustments to the firmness and appearance consistency. It achieves the beneficial effect of directly compressing process steps and facilitating mass production while ensuring complete functionality.

[0025] like Figure 1 As shown, the first part 31 is a flexible component, while the second part 32 and the third part 33 are rigid plates.

[0026] As can be seen from the above description, the first part 31 is a flexible component with strong deformation ability, which will not affect the computer's placement and removal in the computer bag; the second part 32, the third part 33 and the bottom cover 2 can form a triangular structure, which can stably support the computer.

[0027] like Figure 2 and Figure 4 As shown, the junction area between the first part 31 and the second part 32 is further bonded, welded or sewn to the bottom cover 2.

[0028] As can be seen from the above description, there are multiple ways to fix the folding bracket 3 and the bottom cover 2, which helps to enrich the diversity of computer bags.

[0029] like Figure 2 As shown, further, the inner surface of the top cover 1 is velvet, and the first Velcro 11 is a portion of the inner surface of the top cover 1; or, the inner surface of the bottom cover 2 is velvet, and the second Velcro 21 is a portion of the inner surface of the bottom cover 2.

[0030] As described above, the fleece surface can effectively protect the computer stored in the computer bag. Utilizing a portion of the fleece surface as the rough side of the Velcro assembly further facilitates the processing and manufacturing of the computer bag.

[0031] like Figure 1 As shown, the folding bracket 3 is further centered relative to the bottom cover 2.

[0032] As can be seen from the above description, the centrally positioned folding bracket 3 allows the top cover 1 to be subjected to more balanced forces.

[0033] like Figure 2 and Figure 3 As shown, the third Velcro 5 is further positioned away from the boundary area between the first part 31 and the second part 32.

[0034] As can be seen from the above description, the third hook and loop fastener 5 is positioned away from the junction area between the first part 31 and the second part 32, which makes it convenient for the user to connect the third hook and loop fastener 5 to the top cover 1.

[0035] like Figure 5 As shown, the third part 33 has an extension 331 on the side away from the second part 32, and the fourth Velcro 6 is disposed on the extension 331.

[0036] As can be seen from the above description, the presence of the extension portion 331 allows the user to more easily connect the fourth Velcro 6 to the bottom cover 2.

[0037] Furthermore, the extension portion 331 is rotatable relative to other regions of the third portion 33.

[0038] As described above, the rotatable extension 331 allows the user to easily connect the fourth Velcro 6 to the bottom cover 2.

[0039] like Figure 1 and Figure 7 As shown, the bottom cover 2 further has a receiving groove 22 for receiving the second part 32 and the third part 33.

[0040] As can be seen from the above description, using the receiving slot 22 to house the second part 32 and the third part 33 can prevent the folding bracket 3 from damaging the computer stored in the computer bag.

[0041] like Figure 7 As shown, further, the bottom cover 2 is provided with corner bands 7 at its two corners, and the corner bands 7 are located away from the junction area between the first part 31 and the second part 32.

[0042] As described above, the corner strap 7 can restrain the corners of the computer supported by the folding stand 3, thereby preventing the computer from slipping on the folding stand 3.

[0043] The first embodiment of this utility model is a computer bag, used to store laptops, tablets, etc., and when necessary, it can also provide support for laptops and tablets in use, so that the laptops and tablets can be kept in an inclined position, thereby facilitating user use.

[0044] Please refer to Figures 1 to 6 The computer bag includes a top cover 1, a bottom cover 2, and a folding bracket 3. The top cover 1 is provided with a first Velcro 11. The bottom cover 2 is rotatably connected to the top cover 1 and is provided with a second Velcro 21. There are various ways to achieve the rotatable connection between the bottom cover 2 and the top cover 1, such as connecting through a flexible sheet 4 or connecting through a hinge. The folding bracket 3 includes a first part 31, a second part 32, and a third part 33 connected in sequence. The first part 31 and the third part 33 are rotatable relative to the second part 32. The junction area between the first part 31 and the second part 32 is fixed on the bottom cover 2. The first part 31 has a third Velcro 5 that cooperates with the first Velcro 11, and the third part 33 has a fourth Velcro 6 that cooperates with the second Velcro 21.

[0045] Preferably, the first part 31 is a flexible component, while the second part 32 and the third part 33 are rigid boards. The folding bracket 3 is an integral structure. In a specific product, the first part 31, the second part 32, and the third part 33 can be a single piece of fabric, leather, etc., and then the rigid boards are fixed to the second part 32 and the third part 33 respectively. Of course, it is also possible for the first part 31 to be fixedly connected to one side of the second part 32 of the rigid board structure, and for the third part 33 of the rigid board structure to be fixedly connected to the second part 32 through a flexible component (including but not limited to fabric, leather, etc.). The rigid board can be cardboard, plastic board, metal plate, etc.

[0046] like Figure 4 As shown, the junction area of ​​the first part 31 and the second part 32 is bonded, fused or sewn to the bottom cover 2. To ensure the structural stability of the computer bag, it is preferable that the junction area of ​​the first part 31 and the second part 32 is sewn to the bottom cover 2 by a sewing thread.

[0047] like Figure 2 As shown, in a preferred embodiment, the inner surface of the top cover 1 is a velvet surface, and the first hook and loop fastener 11 is a portion of the inner surface of the top cover 1; or, the inner surface of the bottom cover 2 is a velvet surface, and the second hook and loop fastener 21 is a portion of the inner surface of the bottom cover 2. In this way, the velvet surface not only protects the computer but also serves as the rough surface of the hook and loop fastener assembly, achieving multiple uses and further simplifying the production process of the computer bag. In this case, the third hook and loop fastener 5 and the fourth hook and loop fastener 6 are the hook surfaces of the hook and loop fastener assembly, respectively.

[0048] like Figure 1 and Figure 7 As shown, in this embodiment, the folding bracket 3 is centrally positioned relative to the bottom cover 2. In other embodiments, the number of folding brackets 3 may be multiple, and the multiple folding brackets 3 may be evenly distributed relative to the bottom cover 2.

[0049] Please combine Figure 2 and Figure 3 The third hook and loop fastener 5 is positioned away from the boundary area between the first part 31 and the second part 32. Optionally, the third part 33 has an extension 331 on the side away from the second part 32, and the fourth hook and loop fastener 6 is disposed on the extension 331. Preferably, the extension 331 is rotatable relative to other areas of the third part 33, and the extension 331 can be either rigid or flexible.
