[0038] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0039] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0040] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0041] In the field of toolboxes, especially those for storing heavy tools, toolboxes must have good impact resistance. To increase the impact resistance of toolboxes, conventional toolboxes are equipped with shock-absorbing foam inside, have thicker walls, and use a higher proportion of shock-absorbing materials during the toolbox molding process. However, for ease of transportation and space saving, toolboxes are generally rectangular in shape, and it has been found that the top corners of the toolbox are the weakest points most vulnerable to impact and damage.

[0042] This utility model embodiment provides a toolbox, which is specially improved at the weakest point of the toolbox to improve the overall impact resistance of the toolbox.

[0043] refer to Figures 1 to 6This utility model provides a toolbox 100 including a box body 20 and a lid 10, with the lid 10 hinged to the box body 20. The box body 20 includes a bottom 22 and side walls 21, which define a receiving area. The lid 10 and the bottom 22 are symmetrically arranged with respect to the side walls 21. The lid 10 is rotatable relative to the box body 20 and can switch between an open and closed state. In the closed state, the lid 10 can cover the receiving space formed by the box body 20 to accommodate and store various items.

[0044] like Figure 1 As shown, a locking mechanism 30 is provided between the cover 10 and the box 20, which locks the cover 10 and the box 20 in a closed state. In this embodiment, the toolbox 100 has two locking mechanisms 30 arranged symmetrically along the length of the toolbox 100 to ensure stable locking. The locking mechanism 30 can be a conventional snap-on lock, a latch lock, a magnetic lock, or a combination lock, etc., which will not be described in detail here.

[0045] Continue to refer to Figure 1 , Figure 2 as well as Figure 5 and Figure 6 Each corner of the bottom 22 of the toolbox 100 has a groove 40, and each corner of the cover 10 also has a groove 100. When the corner of the toolbox 100 is impacted, the gaps formed by the grooves 40 provide greater deformation space at the corner. The material of the toolbox 100 can undergo bending, compression, and other deformations to a certain extent within the allowable range of the gaps. Thus, the kinetic energy generated by the impact is converted into other forms of energy, such as the elastic potential energy of the material, effectively improving the impact resistance at the corner.

[0046] The bottom of the groove 40 has a rounded transition. The rounded transition of the groove 40 has no obvious corners. When the top corner is hit, the impact force can be evenly distributed and transmitted along the arc, making the force application smoother and greatly reducing the possibility of high stress at the top corner, thus further improving the impact resistance of the toolbox 100.

[0047] Furthermore, each groove 40 extends front to back and is continuous along the front of its apex. The continuous groove 40 allows more space for deformation at the apex when impacted, and prevents concentrated stress at the apex.

[0048] In this embodiment, the toolbox 100 is roughly rectangular in shape with eight corners. The lid 10 has four corners, and the bottom 22 of the box body 20 has four corresponding corners. At least one groove 40 is provided on each of the eight corners. The number of grooves 40 at each corner depends on factors such as the material of the toolbox 100, the width of the grooves 40, and the area of ​​the corner. Here, only one groove 40 at each corner is used as an example for illustration. Following the principle of optimal symmetrical arrangement of the toolbox 100, in the embodiment described in this application, the size and position of the corners of the box body 20 and the lid 10 are mirror-symmetrical about the toolbox 100 along its height axis; the structural shape of each groove 40 is also consistent.

[0049] Continue to refer to Figure 5 and Figure 6 In this embodiment, the ratio of the width of the groove 40 to the length of the hypotenuse of its apex is between 15% and 25%. The width of the groove 40 is L, and the length of the hypotenuse of the apex may vary. For example, in this embodiment, for the aesthetic purposes of the toolbox 100, each apex is trapezoidal, with an upper hypotenuse length of L1 and a lower hypotenuse length of L2. Correspondingly, the width L of the groove 40 is 15% to 25% of the average length of the upper and lower hypotenuses, i.e., L = (L1 + L2) / 2 × (15% to 25%). The width of the groove 40 relative to the apex is moderate, providing suitable deformation space and stress dispersion for the apex, while at the same time, without sacrificing too much structural strength of the apex or causing the apex to lose too much load-bearing capacity.

[0050] In this embodiment, the ratio of the depth of the groove 40 to the wall thickness of the apex corner is between 1 / 2 and 2 / 3. This ratio range allows the depth of the groove 40 to be well matched with the width of the apex corner. When the apex corner is impacted, the groove 40 can absorb and dissipate energy through greater deformation. At the same time, the depth of the groove 40 will not compromise the stability of the apex corner and its surrounding structure.

[0051] In this embodiment, the plane containing each apex corner has a preset angle α with the plane containing the corresponding sidewall 21 along the height direction. The absolute value of the preset angle α ranges from 30 degrees to 60 degrees. Since the angle between the plane containing each apex corner of the cover 10 and the plane containing the corresponding sidewall 21 along the height direction is α, the angle between the plane containing each apex corner of the bottom 22 and the plane containing the corresponding sidewall 21 along the height direction is also α.

[0052] Furthermore, the multiple auxiliary grooves 50 provided along the width direction of the bottom 22 or the cover 10, with the auxiliary grooves located at the top corners, also increase the deformation space in the width direction of the toolbox 100. Furthermore, the auxiliary grooves 50 are positioned near the top corners, and are adjacent to the grooves 40, effectively expanding the space for dispersing impact stress in the grooves 40. Furthermore, the multiple auxiliary grooves 50 are equidistantly distributed, forming a regular and periodic structure in the width direction of the toolbox 100, thereby effectively and uniformly dispersing the impact force.

[0053] Continue to refer to Figures 3 to 4 In this embodiment, the toolbox 100 is specifically constructed as follows. The bottom 22 has a bottom surface 220 and sloping bottom sidewalls, wherein the sloping bottom sidewalls connect the bottom surface 220 and the sidewalls 21 respectively. The sloping bottom sidewalls include a first long bottom wall 224, a second long bottom wall 226 parallel to the first long bottom wall 224 and of equal length, a first wide bottom wall 221, a second wide bottom wall 223 parallel to the first wide bottom wall 221 and of equal length, a first bottom corner wall 2201 connecting the first long bottom wall 224 and the first wide bottom wall 221, a second bottom corner wall 2202 connecting the first long bottom wall 224 and the second wide bottom wall 223, a third bottom corner wall 2203 connecting the second long bottom wall 226 and the first wide bottom wall 221, and a fourth bottom corner wall 2204 connecting the second long bottom wall 226 and the second wide bottom wall 223.

[0054] The cover 10 includes a top surface 110 and an inclined cover sidewall connected to the top surface 110. In the closed state, the inclined cover sidewall engages with the sidewall 21. The inclined cover sidewall includes a first long cover wall 114, a second long cover wall 116 parallel to the first long cover wall 114 and of equal length, a first wide cover wall 111, a second wide cover wall 113 parallel to the first wide cover wall 111 and of equal length, a first corner wall 1111 connecting the first long cover wall 114 and the first wide cover wall 111, a second corner wall 1112 connecting the first long cover wall 114 and the second wide cover wall 113, a third corner wall 1113 connecting the second long cover wall 116 and the first wide cover wall 111, and a fourth corner wall 1114 connecting the second long cover wall 116 and the second wide cover wall 113.

[0055] There are a total of 8 apex corners, namely the first bottom corner wall 2201, the second bottom corner wall 2202, the third bottom corner wall 2203, the fourth bottom corner wall 2204, the first cap corner wall 1101, the second cap corner wall 1102, the third cap corner wall 1103, and the fourth cap corner wall 1104.

[0056] The length of the first wide bottom wall 221 is less than the length of the first long bottom wall 224, and the ratio of the length of the first bottom corner wall 2201 to the length of the first long bottom wall 224 ranges from 8% to 15%. By limiting the range of the ratio between the length of the apex side of the groove 40 and the length of the long side of the toolbox 100, buffering and transmission are optimized. When the toolbox 100 is impacted, it is ensured that the apex can more easily contact the impact force first, increasing the frequency of the groove 40's role in buffering and resisting impacts.

[0057] In this embodiment, the first wide cover wall 111 and the second wide cover wall 113 are respectively provided with multiple sets of equidistantly arranged auxiliary grooves 50, each set of auxiliary grooves 50 including at least two auxiliary grooves with the same structure. The first wide cover wall 111 and the second wide cover wall 113 are respectively provided with two sets of auxiliary grooves 50, one set of three auxiliary grooves 50, wherein the three auxiliary grooves 50 are equidistant from each other; the other set of two auxiliary grooves 50 are equidistant from each other. The position of each set of auxiliary grooves 50 is located at one of the nearest first cover corner wall 1101, second cover corner wall 1102, third cover corner wall 1103 and fourth cover corner wall 1104.

[0058] In this embodiment, the angle formed by the plane containing the bottom surface 220 and the plane containing the first bottom corner wall 2201 is equal to the angle formed by the plane containing the top surface 110 and the plane containing the first cover corner wall 1111. Further, the angles formed by the plane containing the bottom surface 220 with the planes containing the first bottom corner wall 2201, the second bottom corner wall 2202, the third bottom corner wall 2203, and the fourth bottom corner wall 2204 are all equal. The angles formed by the plane containing the top surface 110 with the planes containing the first cover corner wall 1111, the second cover corner wall 1112, the third cover corner wall 1113, and the fourth cover corner wall 1114 are all equal. This means that the cover 10 and the bottom 22 are symmetrically arranged with respect to the side wall 21.

[0059] The toolbox 100 provided by this utility model has grooves 40 respectively provided at each top corner of the box body 20 and the cover 10. The gaps formed by the grooves 40 expand the deformation space at the top corners, so that when the top corner of the toolbox 100 is impacted, the grooves 40 can buffer the impact force, effectively improving the impact resistance of the toolbox 100. Furthermore, the bottom of the grooves 40 has an arc-shaped transition, and the grooves 40 extend front and back along the surface where the top corner is located and are continuous, further improving the deformation energy absorption effect, thereby improving the overall impact resistance of the toolbox 100.

[0060] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the protection scope of this utility model.
