Description

Technical Field

[0001] This utility model belongs to the field of protection technology, and in particular relates to a corner protection structure. Background Technology

[0002] Due to the large size of charging cabinets or outdoor energy storage base stations, and the presence of edges and corners on their surfaces, these products are prone to deformation during transportation. Currently, to ensure safety and maintain the integrity of the product's appearance during transport, protective structures are typically installed at the edges and corners. However, existing edge protection structures often suffer from poor versatility and low efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a corner protection structure, which aims to solve the technical problems of poor versatility and low efficiency of existing protective plates.

[0004] This utility model is implemented as follows: a corner protection structure for protecting the corners of a cabinet, comprising a first protective plate and a second protective plate arranged at an angle. The first protective plate and the second protective plate intersect to form a corner portion arranged along a first direction. Along the first direction, both the first protective plate and the second protective plate have a first end and a second end. The first end of the first protective plate has a first abutting surface, and the first abutting surface and the corner portion have a first included angle, which is an acute angle. The first end of the second protective plate has a second abutting surface, and the second abutting surface and the corner portion have a second included angle, which is an acute angle.

[0005] In one optional embodiment, a first snap-fit ​​structure is provided at the first abutting surface, and a second snap-fit ​​structure is also provided at the second abutting surface. The first snap-fit ​​structure is used to snap-fit ​​with the second snap-fit ​​structure on the adjacent corner protection structure.

[0006] In one optional embodiment, the second end of the first protective plate has a third abutting surface, the second end of the second protective plate has a fourth abutting surface, the third abutting surface is provided with the second snap-fit ​​structure, and the fourth abutting surface is also provided with the first snap-fit ​​structure.

[0007] In one optional embodiment, the third abutting surface is arranged parallel to the first abutting surface, and the fourth abutting surface is arranged parallel to the second abutting surface.

[0008] In an optional embodiment, the first snap-fit ​​structure includes a snap-fit ​​protrusion, the second snap-fit ​​structure includes a snap-fit ​​groove, and the shape of the snap-fit ​​protrusion is adapted to the shape of the snap-fit ​​groove.

[0009] In one optional embodiment, the mounting groove is an arc-shaped groove, and the top surface of the mounting protrusion is an arc-shaped surface that matches the shape of the arc-shaped groove.

[0010] In an optional embodiment, the first end of the first protective plate and the second protective plate are provided with a first inclined surface, and the second end of the first protective plate and the second protective plate are provided with a second inclined surface, and the inclination angles of the first inclined surface and the second inclined surface are adapted to each other.

[0011] In one alternative embodiment, the sum of the angles of the first included angle and the second included angle is 90°.

[0012] In one optional embodiment, the first protective plate is provided with a plurality of first draft grooves, which are spaced apart along the first direction, and the second protective plate is provided with a plurality of second draft grooves, which are spaced apart along the first direction.

[0013] In one alternative embodiment, the depth of the first draft groove gradually increases from the direction near the second protective plate to the direction away from the second protective plate, and the depth of the second draft groove gradually increases from the direction near the first protective plate to the direction away from the first protective plate.

[0014] The technical advantage of this invention over existing technologies is that it divides the corner protection structure into two parts: a first protective plate and a second protective plate, which are arranged at an angle to each other. The first and second protective plates intersect to form a corner portion along a first direction. In use, the first and second protective plates can be pressed against the two planes forming the corner portion of the cabinet or box, respectively, thus placing the corner portion of the cabinet or box inside the corner portion, thereby protecting the corner portion of the cabinet. Furthermore, along the first direction, both the first protective plate and the second protective plate have a first end and a second end. The first end of the first protective plate has a first abutting surface, and there is a first acute angle between the first abutting surface and the corner. The first end of the second protective plate has a second abutting surface, and there is a second acute angle between the second abutting surface and the corner. This allows one end of the corner protection structure to form a protruding sharp corner structure. When the corner protection structure is installed on the edge near the corner, it can avoid adjacent corner protection structures, or the first abutting surface can directly abut against the second abutting surface on the adjacent corner protection structure, thereby forming a corner protection structure for protecting the corner. Compared with existing cabinet protection structures, this technology allows for the installation of one or more corner protection structures on the edges of cabinets or boxes, or the placement of multiple corner protection structures on the edges of cabinets or boxes to form corner protection structures. This enables the corner protection structure to meet various usage scenarios through different combinations, improving its applicability. It also has the advantages of low cost and high efficiency.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] Please refer to Figures 1 to 3 As shown in the present invention, a corner protection structure 100 is provided, including a first protective plate 1 and a second protective plate 2 arranged at an angle. The first protective plate 1 and the second protective plate 2 intersect to form a corner portion 3 arranged along a first direction. Along the first direction, the first protective plate 1 and the second protective plate 2 each have a first end and a second end. The first end of the first protective plate 1 has a first abutting surface 4, and there is a first included angle between the first abutting surface 4 and the corner portion 3. The first included angle is an acute angle. The first end of the second protective plate 2 has a second abutting surface 5, and there is a second included angle between the second abutting surface 5 and the corner portion 3. The second included angle is an acute angle.

[0030] Specifically, the first protective plate 1 and the second protective plate 2 both refer to plate-shaped components with a certain thickness. The first protective plate 1 and the second protective plate 2 are set at an angle, which matches the angle between the two surfaces of the edge forming the cabinet or box. This angle is usually a right angle. The first protective plate 1 and the second protective plate 2 are typically made of a material with a certain degree of elasticity, such as plastic foam or rubber, which can absorb the impact force on the cabinet or box through elastic deformation. The corner portion 3 refers to the structure formed by the intersection of two plate-shaped objects. The cross-section of the corner portion 3 can be "L"-shaped, where the cross-section refers to the section cut by a plane perpendicular to the first direction. The corner portion 3 can be set along the first direction, which is a direction parallel to both the first protective plate 1 and the second protective plate 2. The first abutting surface 4 and the second abutting surface 5 both refer to surface structures with a certain area. The first abutting surface 4 and the second abutting surface 5 can be planar or curved surfaces, or a combination of curved and planar surfaces. The first contact surface 4 and the second contact surface 5 also intersect at the corner 3. The included angle between the first contact surface 4 and the corner 3 refers to the included angle within the plane range where the first protective plate 1 is located. The included angle between the second contact surface 5 and the corner 3 also refers to the included angle within the plane range where the second protective plate 2 is located.

[0031] The edges of a cabinet or box refer to the part where two surfaces intersect, while the corners of a cabinet or box refer to the part where multiple edges intersect. Since the shape of a cabinet or box is generally a hexahedral structure, the edges of a cabinet or box are generally straight lines, and its corners are usually composed of three intersecting edges.

[0032] The corner protection structure 100 provided in this embodiment of the utility model is divided into two parts: a first protective plate 1 and a second protective plate 2. The first protective plate 1 and the second protective plate 2 are arranged at an included angle, and the first protective plate 1 and the second protective plate 2 intersect to form a corner portion 3 arranged along a first direction. In use, the first protective plate 1 and the second protective plate 2 can be pressed against the two planes forming the corner portion on the cabinet or box, and the corner portion of the cabinet or box can be placed into the corner portion 3, thereby protecting the corner portion of the cabinet. Furthermore, along the first direction, both the first protective plate 1 and the second protective plate 2 have a first end and a second end. The first end of the first protective plate 1 has a first abutting surface 4, and the first abutting surface 4 and the corner portion 3 have a first included angle that forms an acute angle. The first end of the second protective plate 2 has a second abutting surface 5, and the second abutting surface 5 and the corner portion 3 have a second included angle that forms an acute angle. This allows one end of the corner protection structure 100 to form a protruding sharp corner structure. When the corner protection structure 100 is installed on the edge near the corner, it can avoid adjacent corner protection structures 100, or it can directly abut the first abutting surface 4 and the second abutting surface 5 on the adjacent corner protection structure 100 to abut against each other, thereby forming a corner protection structure for protecting the corner of the corner from multiple corner protection structures 100. Compared with the existing corner protection structure 100, during use, one or more corner protection structures 100 can be installed on the edge of the cabinet or box, or multiple corner protection structures 100 can be set on the edge of the cabinet or box to form a corner protection structure. This allows the corner protection structure 100 to meet various usage scenarios through different combination methods, improving the applicability of the corner protection structure 100. At the same time, it also has the advantages of low cost and high efficiency.

[0033] Furthermore, it should be noted that when the corner protection structure 100 is installed on the edge of the cabinet or box, it can remain stable due to its own weight. The corner protection structures 100 can also be interconnected via plug-in structures, thereby maintaining relative stability between multiple corner protection structures 100 and the cabinet or box. Alternatively, after the corner protection structure 100 is installed on the edge of the cabinet or box, wrapping a packaging film (e.g., plastic film) around the outside of the cabinet or box can also maintain relative stability between the corner protection structure 100 and the cabinet or box through the compression of the packaging film.

[0034] In one embodiment, see Figure 1 and Figure 5 A first snap-fit ​​structure 8 is provided at the first abutment surface 4, and a second snap-fit ​​structure 9 is provided at the second abutment surface 5. The first snap-fit ​​structure 8 is used to snap and cooperate with the second snap-fit ​​structure 9 on the adjacent corner protection structure 100. Specifically, both the first snap-fit ​​structure 8 and the second snap-fit ​​structure 9 refer to structures or components that can connect two objects by snap-fitting. The first snap-fit ​​structure 8 can be a slot structure or a protrusion structure. When the first snap-fit ​​structure 8 is a slot structure, the second snap-fit ​​structure 9 is a protrusion structure, and when the first snap-fit ​​structure 8 is a protrusion structure, the second snap-fit ​​structure 9 is a slot structure. In this embodiment, by providing a first snap-fit ​​structure 8 at the first abutting surface 4 and a second snap-fit ​​structure 9 at the second abutting surface 5, when multiple corner protection structures 100 are all located at the corners of the cabinet, the corner protection structures 100 and adjacent corner protection structures 100 can be snapped and fixed together through the first snap-fit ​​structure 8 and the second snap-fit ​​structure 9, thereby connecting the three corner protection structures 100 located at the corners into an integral structure, making the installation of the corner protection structures 100 more secure and reliable.

[0035] In one embodiment, see Figure 1 , Figure 2 and Figure 4The first protective plate 1 has a third abutting surface 6 at its second end, and the second protective plate 2 has a fourth abutting surface 7 at its second end. A second latching structure 9 is provided at the third abutting surface 6, and a first latching structure 8 is also provided at the fourth abutting surface 7. Specifically, both the third abutting surface 6 and the fourth abutting surface 7 refer to surface structures with a certain area. The third abutting surface 6 and the fourth abutting surface 7 can be planar or curved surfaces, or a combination of curved and planar surfaces. The third abutting surface 6 and the fourth abutting surface 7 also intersect at the corner 3. In this embodiment, a third abutting surface 6 and a fourth abutting surface 7 are respectively provided at the second end of the first protective plate 1 and the second end of the second protective plate 2. The third abutting surface 6 and the fourth abutting surface 7 form a groove structure at the end of the corner protection structure 100 that matches the shape of the sharp corner structure at the other end of the corner protection structure 100. In use, multiple corner protection structures 100 can be arranged along the length direction of the edge, and the third abutting surface 6 abuts against the first abutting surface 4 on the adjacent corner protection structure 100, and the fourth abutting surface 7 abuts against the second abutting surface 5 on the adjacent corner protection structure 100. This makes the installation between two adjacent corner protection structures 100 more compact, thereby improving the protective effect of the corner protection structure 100. Meanwhile, a second snap-fit ​​structure 9 is provided at the third contact surface 6, and a first snap-fit ​​structure 8 is provided at the fourth contact surface 7. When multiple corner protection structures 100 are arranged sequentially along the edges of the product, the second snap-fit ​​structure 9 can be snapped together with the first snap-fit ​​structure 8 on other corner protection structures 100, making the assembly of the two corner protection structures 100 more stable.

[0036] In one embodiment, see Figure 1 , Figure 2 and Figure 4 The third abutment surface 6 is arranged parallel to the first abutment surface 4, and the fourth abutment surface 7 is arranged parallel to the second abutment surface 5. In this embodiment, by arranging the third abutment surface 6 and the first abutment surface 4 parallel to each other, and arranging the fourth abutment surface 7 and the second abutment surface 5 parallel to each other, multiple corner protection structures 100 can be arranged along the length direction of the corner, making the splicing between the corner protection structures 100 and the connected corner protection structures 100 more closely fitted, thereby making the assembly of the two corner protection structures 100 more stable.

[0037] In one embodiment, see Figure 1 , Figure 2 and Figure 4The first snap-fit ​​structure 8 includes a snap-fit ​​protrusion 14, and the second snap-fit ​​structure 9 includes a snap-fit ​​groove 15, with the shapes of the snap-fit ​​protrusion 14 and the snap-fit ​​groove 15 being mutually adapted. Specifically, the snap-fit ​​protrusion 14 refers to a component with a certain height, and the snap-fit ​​protrusion 14 can be block-shaped, plate-shaped, or strip-shaped. The snap-fit ​​groove 15 refers to a groove structure with a certain depth. In this embodiment, the snap-fit ​​connection between the two can be achieved by snapping the snap-fit ​​protrusion 14 into the snap-fit ​​groove 15, which makes the snap-fit ​​between the first snap-fit ​​structure 8 and the second snap-fit ​​structure 9 more convenient, and at the same time, it can simplify the overall structure of the corner protection structure 100 and reduce the production cost of the corner protection structure 100.

[0038] In one embodiment, see Figure 4 and Figure 5 The mounting groove 15 is an arc-shaped groove, and the top surface of the mounting protrusion 14 is an arc-shaped surface that matches the shape of the arc-shaped groove. Specifically, by setting the mounting groove 15 as an arc-shaped groove and the top surface of the mounting protrusion 14 as an arc-shaped surface that matches the shape of the arc-shaped groove, it is easier for the mounting protrusion 14 to be inserted into the arc-shaped groove, and it is easier to connect the two corner protection structures 100.

[0039] In one embodiment, see Figure 1 and Figure 2 When the corner protection structure 100 is installed on the protected object (such as a cabinet or box), along the thickness direction of the first protective plate 1, the surface of the first protective plate 1 facing away from the protected object is the outer surface of the first protective plate 1, and the surface of the first protective plate 1 facing the protected object is the inner surface of the first protective plate 1. Similarly, along the thickness direction of the second protective plate 2, the surface of the second protective plate 2 facing away from the protected object is the outer surface of the second protective plate 2, and the surface of the second protective plate 2 facing the protected object is the inner surface of the second protective plate 2.

[0040] The first protective plate 1 and the second protective plate 2 are provided with a first inclined surface 10 at their first ends and a second inclined surface 11 at their second ends. The inclination angles of the first inclined surface 10 and the second inclined surface 11 are adapted to each other. Specifically, the first inclined surface 10 refers to a surface structure with a certain area. The first inclined surface 10 located at the first end of the first protective plate 1 is inclined relative to the first abutting surface 4. At this time, the inclination direction of the first inclined surface 10 can be relative to the plane on which the entire first protective plate 1 is located. The first inclined surface 10 located at the first end of the second protective plate 2 is inclined relative to the second abutting surface 5. At this time, the inclination direction of the first inclined surface 10 can be relative to the plane on which the entire second protective plate 2 is located. The second inclined surface 11 refers to a surface structure with a certain area. The second inclined surface 11 located at the second end of the first protective plate 1 is inclined relative to the third abutting surface 6. At this time, the direction of inclination of the second inclined surface 11 can be inclined relative to the plane where the entire first protective plate 1 is located. The second inclined surface 11 located at the second end of the second protective plate 2 is inclined relative to the fourth abutting surface 7. At this time, the direction of inclination of the second inclined surface 11 can be inclined relative to the plane where the entire second protective plate 2 is located.

[0041] The inclination angles of the first inclined surface 10 and the second inclined surface 11 are adapted; for example, when one of the first inclined surface 10 and the second inclined surface 11 is an externally tangent inclined surface, the other can be an internally tangent inclined surface. Specifically, the first inclined surface 10 of the first protective plate 1 is connected between the first abutting surface 4 and the outer surface of the first protective plate 1. The first inclined surface 10 of the first protective plate 1 is inclined relative to the outer surface of the first protective plate 1 and the first abutting surface 4. The second inclined surface 11 of the first protective plate 1 is connected between the third abutting surface 6 and the inner surface of the first protective plate 1. The second inclined surface 11 of the first protective plate 1 is inclined relative to the inner surface of the first protective plate 1 and the third abutting surface 6. The angle between the first inclined surface 10 of the first protective plate 1 and the outer surface of the first protective plate 1 is the first inclination angle. The angle between the second inclined surface 11 of the first protective plate 1 and the inner surface of the first protective plate 1 is the second inclination angle. The first inclination angle and the second inclination angle are equal (a certain error is allowed).

[0042] The first inclined surface 10 of the second protective plate 2 is connected between the second abutment surface 5 and the outer surface of the second protective plate 2. The first inclined surface 10 of the second protective plate 2 is inclined relative to the outer surface of the second protective plate 2 and the second abutment surface 5. The second inclined surface 11 of the second protective plate 2 is connected between the fourth abutment surface 7 and the inner surface of the second protective plate 2. The first inclined surface 10 of the second protective plate 2 is inclined relative to the inner surface of the second protective plate 2 and the fourth abutment surface 7. The angle between the first inclined surface 10 of the second protective plate 2 and the outer surface of the second protective plate 2 is the third inclined angle. The angle between the second inclined surface 11 of the second protective plate 2 and the inner surface of the second protective plate 2 is the fourth inclined angle. The third inclined angle and the fourth inclined angle are equal (a certain error is allowed).

[0043] In this embodiment, by providing a first inclined surface 10 at the first end of the first protective plate 1 and the second protective plate 2, and providing a second inclined surface 11 at the second end of the first protective plate 1 and the second protective plate 2, and by matching the inclination angles of the first inclined surface 10 and the second inclined surface 11, a certain guiding effect can be achieved when the mounting protrusion 14 and the mounting groove 15 are engaged with each other, making it more convenient and faster to connect the two corner protection structures 100 to each other.

[0044] In one embodiment, see Figure 1 and Figure 2 The sum of the first included angle and the second included angle is 90°. Specifically, the sum of the first included angle and the second included angle is 90°. For example, when the first included angle is 30°, the second included angle is 60°; when the first included angle is 45°, the second included angle is 45°. It should be noted that the sum of the first included angle and the second included angle is not absolutely 90°; a certain margin of error is allowed. In this embodiment, by making the sum of the first included angle and the second included angle 90°, when multiple corner protection structures 100 are all located at the corners of the cabinet, the first abutting surface 4 on the first corner protection structure 100 can be angled to match the second abutting surface 5 on the second corner protection structure 100, thus making the contact between them tighter. Simultaneously, the second abutting surface 5 on the first corner protection structure 100 and the first abutting surface 4 on the third corner protection structure 100 are angled to match, thus making the contact between them tighter. It can also make the first contact surface 4 on the second corner protection structure 100 and the second contact surface 5 on the third corner protection structure 100 fit together at an angle, so that the two contact each other more closely.

[0045] In one embodiment, see Figure 1 and Figure 2 The first protective plate 1 and the second protective plate 2 are integrally formed, and the snap-fit ​​protrusion 14 and the corner protection structure 100 are also integrally formed. Specifically, the first protective plate 1 and the second protective plate 2 are integrally formed, and the snap-fit ​​protrusion 14 and the corner protection structure 100 are also integrally formed, which makes the overall strength of the corner protection structure 100 better.

[0046] In one embodiment, see Figure 1 and Figure 2The first protective plate 1 is provided with a plurality of first draft grooves 12, which are spaced apart along a first direction. The second protective plate 2 is provided with a plurality of second draft grooves 13, which are also spaced apart along the first direction. Specifically, both the first draft grooves 12 and the second draft grooves 13 refer to groove structures with a certain depth. In this embodiment, by providing a plurality of first draft grooves 12 on the first protective plate 1, which are spaced apart along the first direction, and providing a plurality of second draft grooves 13 on the second protective plate 2, which are also spaced apart along the first direction, the overall volume of the corner protection structure 100 is reduced. This reduces the amount of material used in the manufacturing process of the corner protection structure 100, thereby lowering the overall manufacturing cost of the corner protection structure 100.

[0047] In one embodiment, see Figure 1 and Figure 2 The depth of the first draft groove 12 gradually increases from the direction near the second protective plate 2 to the direction away from the second protective plate 2, and the depth of the second draft groove 13 gradually increases from the direction near the first protective plate 1 to the direction away from the first protective plate 1. Specifically, by gradually increasing the depth of the first draft groove 12 from the direction near the second protective plate 2 to the direction away from the second protective plate 2, and gradually increasing the depth of the second draft groove 13 from the direction near the first protective plate 1 to the direction away from the first protective plate 1, the bottom surface of the first draft groove 12 is inclined relative to the outer surface of the first protective plate 1, and the bottom surface of the second draft groove 13 is inclined relative to the outer surface of the second protective plate 2, the corner protection structure 100 can be demolded more easily, and the manufacturing difficulty and cost of the mold are reduced.

[0048] The above are merely preferred embodiments of the present utility model, and only specifically describe the technical principles of the present utility model. These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model, as well as other specific embodiments of the present utility model that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of the present utility model.
