Description

Technical Field

[0001] This utility model relates to the technical field of anti-collision accessories, and in particular to an anti-collision corner protector for a laptop bag. Background Technology

[0002] A laptop bag is a bag specifically designed to store laptops for easy carrying.

[0003] With the development of laptops, they have become more sophisticated and expensive. To better protect laptops, in addition to increasing the thickness of the protective layer of the bag, protective structures are often added at the corners. For example, Chinese patent document CN207461637U discloses a laptop bag corner protector, which includes at least an inner corner protector layer at the corner of the laptop bag. The upper surface of the end of the inner corner protector layer extends outward to form a protrusion, and the upper surface of the middle part of the inner corner protector layer extends inward to form a groove. Under the action of external force, the upper surface of the inner corner protector layer can bend towards the laptop, with the protrusion acting on the side of the laptop and the groove contacting the corner of the laptop. In this way, the groove makes the corner protector easy to bend, and the protrusion provides impact protection for the laptop.

[0004] However, the existing anti-collision corner protection structure has the following shortcomings: the protrusion, as a structure that comes into contact with the computer, is a solid structure, and the degree of anti-collision protection for the computer depends on the elastic properties of the material itself. Therefore, there is room for further improvement in anti-collision protection performance. Secondly, a solid structure means that more materials are needed. Therefore, in order to improve the anti-collision protection performance of the corner protection while effectively reducing manufacturing costs, the laptop bag anti-collision corner protection of this application is proposed. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a laptop bag anti-collision corner protector that effectively improves anti-collision performance while saving materials to reduce manufacturing costs.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A laptop bag with impact-resistant corner protectors, comprising:

[0008] A long strip body has several spaced protrusions on one side of its middle section, and the height of each protrusion decreases from the middle of the long strip body towards both ends. A protrusion is provided on each end of the long strip body away from the protrusions. The protrusion is formed by the side of the long strip body away from the protrusions and recessed towards the side of the protrusions. A hollow groove is correspondingly formed on the side of the long strip body away from the protrusions.

[0009] Optionally, the side of the elongated body near the protrusion or raised portion is a wavy surface, the protrusion is located on the concave side of the wavy surface, and the raised portion is located on the convex side of the wavy surface.

[0010] Optionally, a groove is provided laterally on the side of the elongated body away from the protrusion.

[0011] Optionally, at least one empty material groove is provided at both ends of the long strip body away from the groove, and the empty material groove extends into the protrusion.

[0012] Optionally, an end piece is provided at each end of the long strip body.

[0013] Optionally, the width of the end piece is greater than the width of the elongated body.

[0014] Optionally, the overall projection surface of each of the protrusions and the projection surface of the protrusion are both elliptical.

[0015] Optionally, the surface of the protrusion has an arc-shaped structure.

[0016] Optionally, the elongated body, the protrusion, and the raised portion are integrally formed soft rubber structures.

[0017] Compared with the prior art, the present invention has at least the following advantages:

[0018] This utility model discloses a laptop bag anti-collision corner protector, comprising a long strip body. Several spaced-apart protrusions are arranged on one side of the middle section of the long strip body, with the height of each protrusion decreasing from the middle towards both ends. A raised portion is provided at each end of the long strip body away from the protrusions. The raised portion is formed by a recess from the side of the long strip body away from the protrusion towards the side closer to the protrusion, and a corresponding hollow groove is formed on the side of the long strip body away from the raised portion. Thus, the hollow grooves formed on the back side of each raised portion reduce the amount of material used while creating a bubble-like structure for the raised portion, effectively enhancing its elasticity and providing better impact cushioning for the laptop.

[0027] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0028] like Figures 1 to 5 As shown, a laptop bag anti-collision corner protector 10 includes a long strip body 110. A plurality of spaced protrusions 120 are provided on one side of the middle portion of the long strip body 110, and the height of each protrusion 120 decreases from the middle portion of the long strip body 110 towards both ends. A protrusion 130 is provided on each end of the long strip body 110 away from the protrusions 120. The protrusion 130 is formed by recessing from the side of the long strip body 110 away from the protrusions 120 to the side of the long strip body 110 close to the protrusions 120. A hollow groove 111 is correspondingly formed on the side of the long strip body 110 away from the protrusions 130.

[0029] It should be noted that the laptop bag anti-collision corner protector 10 of this application is used for installation at the corner of the laptop bag. Specifically, the middle part of the elongated body 110 is concave inward at the positions of the protrusions 120, so that the protrusions 120 are close to each other, ultimately transforming the planar elongated body 110 into a right-angled structure. Two protrusions 130 are located on the inner side of the formed right-angled structure, and the protrusions 130 are used to abut against the two adjacent right-angled sides of one of the right-angled structures of the laptop. It should be noted that a hollow groove 111 is formed on the back side of the protrusion 130, so the protrusion 130 is not a solid structure. In this way, material can be saved at the position of the protrusion 130, thereby reducing the overall cost of the anti-collision corner protector. Secondly, the anti-collision cushioning performance of the protrusion 130 no longer depends solely on the elasticity of the material itself. The hollow groove 111 formed on the back side of the protrusion 130 makes the protrusion 130 form a bubble-like structure. This effectively enhances the elasticity of the protrusions 130, thus providing better shock absorption for the computer. Furthermore, the protrusions 120 are equidistant from each other, and the height of the protrusions 120 gradually decreases towards both ends. Thus, when the long strip body 110 bends at the position of the protrusions 120, the protrusions 120 will be squeezed together. By setting the structure of equidistant distribution of the protrusions 120 and decreasing height, it can be ensured that the curvature of each position in the middle of the long strip body 110 tends to be consistent, and the protrusions 120 are prevented from affecting the bending of the long strip body 110.

[0030] Furthermore, such as Figure 5 As shown, in one embodiment, the side of the elongated body 110 near the protrusion 120 and the protrusion 130 is a wavy surface, the protrusion 120 is located on the concave side of the wavy surface, and the protrusion 130 is located on the convex side of the wavy surface.

[0031] It should be noted that the protrusion 130 is used to abut against the computer to provide impact cushioning, while the corresponding position of the bump 120 is designed to facilitate bending. Since the material at the bending location is too thick, bending becomes difficult; however, thicker material provides stronger impact resistance. Therefore, the surface of the elongated body 110 is designed with a wavy structure, with the bump 120 located at the concave part of the wavy surface. This concave part has a smaller thickness, thus facilitating bending. The protrusion 130 is located at the convex part of the wavy surface, which has a larger thickness, thus providing higher impact resistance.

[0032] like Figure 2 and Figure 5 As shown, in one embodiment, a groove 112 is provided laterally on the side of the elongated body 110 away from the protrusion 120.

[0033] It should be noted that the middle part of the elongated body 110 needs to be bent towards the protrusion 120. Therefore, on the side of the elongated body 110 away from the protrusion 120, and at the position corresponding to the protrusion 120, tensile stress will occur due to the bending. To prevent the elongated body 110 from tearing due to tensile stress, a groove 112 is laterally formed at this position. In one embodiment, the groove 112 is a semi-circular arc structure.

[0034] like Figure 2 and Figure 3 As shown, in one embodiment, at least one empty material groove 113 is provided on both ends of the long strip body 110 away from the groove 112, and the empty material groove 113 extends into the protrusion 120.

[0035] It should be noted that, in order to further reduce the tensile stress on the middle part of the elongated body 110 during bending, empty material grooves 113 are also provided on both sides of the groove 112, wherein each empty material groove 113 corresponds to a protrusion 120, so that the empty material groove 113 extends into the protrusion 120. In one embodiment, two empty material grooves 113 are provided, and the two empty material grooves 113 are respectively located on both sides of the groove 112. In this way, not only can the tensile stress on the middle part of the elongated body 110 during bending be reduced, but also the amount of material at the corresponding positions of the elongated body 110 and the protrusion 120 can be reduced, thereby reducing manufacturing costs.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, in one embodiment, an end piece 140 is provided on each of the two ends of the long strip body 110.

[0037] It should be noted that, in order to facilitate the installation of the laptop bag anti-collision corner protector 10 on the laptop bag, an end piece 140 is provided at each end of the long strip body 110. Thus, the laptop bag anti-collision corner protector 10 can be sewn or glued to the laptop bag using the end pieces 140. Furthermore, in one embodiment, the width of the end piece 140 is greater than the width of the long strip body 110. This increases the contact area between the laptop bag anti-collision corner protector 10 and the laptop bag, thereby improving the strength of the laptop bag anti-collision corner protector 10 when installed on the laptop bag.

[0038] like Figure 4As shown, in one embodiment, the overall projection surface of each protrusion 120 and the projection surface of the protrusion 130 are both elliptical. Furthermore, the overall projection surface a of each protrusion 120 and the projection surfaces b of the two protrusions 130 are both elliptical structures of the same area. Moreover, the overall projection surface a of each protrusion 120 and the projection surfaces b of the two protrusions 130 are arranged in a sequentially connected layout. This makes the laptop bag's anti-collision corner protectors 10 more symmetrical overall, and when bent and mounted on the laptop bag, they can better protect the right-angled edges of the laptop from impacts.

[0039] like Figure 3 and Figure 5 As shown, in one embodiment, the surface of the protrusion 130 has an arc-shaped structure. Specifically, the protrusion 130 has a structure that is high in the middle and low at both ends, which can improve the impact-absorbing performance of the protrusion 130.

[0040] In one embodiment, the elongated body 110, the protrusion 120, the raised portion 130, and the end piece 140 are integrally molded soft rubber structures. For example, silicone material can be used for integral molding using an injection mold.

[0041] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood as including, but not limited to, locking and fixing with screws / bolts, welding, or bonding with adhesives, wherein the adhesives used can be commercially available finished products. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
