Abstract

This application provides a protective structure and distribution box, including a protective frame. The protective frame includes two sets of protective parts and a buffer part. The two sets of protective parts and the buffer part are distributed along a first direction. The buffer part is installed between the two sets of protective parts and is placed along the first direction. The two ends of the buffer part are fixedly connected to the protective parts on both sides. By installing a buffer part between the two sets of protective parts, when the protective frame is impacted by an external force along the first direction, the impact load is transferred to the buffer part through the protective parts, thereby causing the buffer part to deform and absorb the impact load, reducing the risk of components being squeezed during the impact. When the buffer part is squeezed to the limit position, the two sets of protective parts form a rigid connection through the buffer part, thereby strengthening the strength of the protective frame, further reducing the risk of component damage, and providing a safe environment for the normal operation of the components.

Description

Technical Field

[0001] This application relates to the field of distribution boxes, and more particularly to a protective structure and a distribution box. Background Technology

[0002] The distribution box is the control center that directs the rational allocation of electrical energy among the various components in the power supply line. The components are installed on the side walls of the inner cavity of the distribution box.

[0003] Conventional distribution boxes are made of sheet metal, including the box body and the box door. The box door is hinged to the box body, and the distribution box can be adapted to indoor and outdoor environments.

[0004] Because the distribution box is made of sheet metal bending and forming process, when the distribution box is hit from the side of the door, the door and the box body will bend and deform, which will squeeze the components in the internal cavity of the distribution box, causing damage to the components and short circuits, and a series of other problems, which can easily lead to major safety accidents.

[0005] Therefore, how to design a protective structure that can reduce the risk of component damage from frontal impacts on the distribution box has become a technical problem that urgently needs to be solved by people in this field. Utility Model Content

[0006] This application provides a protective structure and a distribution box to at least solve the above-mentioned technical problems existing in the prior art.

[0007] A protective structure and a protective frame are provided. The protective frame includes two sets of protective parts and a buffer part. The two sets of protective parts and the buffer part are distributed along a first direction. The buffer part is installed between the two sets of protective parts and is placed along the first direction. The two ends of the buffer part are fixedly connected to the protective parts on both sides respectively.

[0008] In one embodiment, the protective part includes a frame connected end to end and a support rod. The plane of the frame is perpendicular to the first direction. The support rod is fixedly installed on the frame and extends along the first direction toward the buffer part. The buffer part is fixedly connected to the support rod.

[0009] In one embodiment, the frame includes two first pillars extending along a third direction, the two first pillars being distributed along a second direction, and also includes two angle irons extending along the second direction, the two angle irons being distributed along a third direction, the angle irons having an L-shaped cross-section, and being welded to both ends of the first pillars respectively.

[0010] In one embodiment, the end wall of the first support column is provided with a first locking interface opening towards the buffer part, and the end wall of the support rod near the first support column is provided with a second locking interface. When the support rod is installed with the first support column, the first locking interface and the second locking interface are engaged, and the end wall of the support rod abuts against the inner wall of the first locking interface.

[0011] In one embodiment, the angle iron is welded to the first support column and the support rod.

[0012] In one embodiment, a limiting baffle is welded onto the angle iron, and the limiting baffle abuts against the side wall of the first pillar and the support rod to restrict the sliding of the first pillar and the support rod along the second direction.

[0013] In one embodiment, the buffer section is an energy-absorbing box, which is fixedly connected to the support rod by positioning bolts, and the positioning bolts are arranged along a first direction.

[0014] In one embodiment, the two first pillars of one set of protective parts are provided with insertion slots on the same horizontal plane, and also include a reinforcing tube arranged along the second direction. The two ends of the reinforcing tube are respectively inserted into the insertion slots of the two first pillars. The reinforcing tube and the first pillars are riveted together by rivets, and the end wall of the reinforcing tube abuts against the inner wall of the insertion slot.

[0015] In one embodiment, a support plate is also included, which is fixed to the reinforcing tube for mounting components.

[0016] A distribution box, wherein the outer wall of the protective frame is covered with a box body formed by sheet metal forming an opening on one side, and the sheet metal is fixed to the protective frame by welding or riveting.

[0017] Compared with the prior art, the protective structure and distribution box of this application have the following advantages: This application installs a buffer section between two sets of protective sections. When the protective frame is impacted by an external force along the first direction, the impact load is transferred to the buffer section through the protective section, causing the buffer section to deform and absorb the impact load. This reduces the risk of components being squeezed during the impact. When the buffer section is squeezed to its limit, the two sets of protective sections form a rigid connection through the buffer section, thereby strengthening the protective frame and further reducing the risk of component damage, providing a safe environment for the normal operation of the components.

[0022] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] The protective structure in this application is mainly used to be installed inside the distribution box to strengthen the distribution box and absorb the load of external impacts on the distribution box, reducing the risk of components being damaged by compression.

[0024] It is worth noting that the protective structure includes a protective frame 1, which is installed inside the distribution box to enhance the strength of the distribution box.

[0025] Example 1: The direction of this application is redefined, such as... Figure 1 As shown, the width direction of the protective frame 1 is defined as the first direction X, the length direction of the protective frame 1 is defined as the second direction Y, and the height direction of the protective frame 1 is defined as the third direction Z. The first direction X can also refer to the front and back direction of the distribution box, the second direction Y can refer to the left and right direction of the distribution box, and the third direction Z can also refer to the height direction of the distribution box.

[0026] Among them, such as Figure 1 and Figure 2 As shown, the protective frame 1 includes two sets of protective parts 11 and one set of buffer parts 12. The two protective parts 11 and the buffer parts 12 are distributed along the first direction X, i.e., the front-to-back direction. It is worth noting that the buffer parts 12 are installed between the two sets of protective parts 11. The buffer parts 12 are arranged along the first direction X, and the two ends of the buffer parts 12 are fixedly connected to the protective parts 11 respectively.

[0027] It is worth noting that the components inside the distribution box are installed in the cavity formed by the protective frame 1. When the protective frame 1 is subjected to an impact load along the first direction X, the protective part 11 transfers the load to the buffer part 12. At this time, the buffer part 12 absorbs the load and deforms, thereby reducing the risk of impact to the components inside the protective frame 1.

[0028] Furthermore, the buffer section 12 adopts an energy-absorbing box, wherein the energy-absorbing box is arranged along the first direction X. When the protective frame 1 is subjected to an impact load in the first direction X, the energy-absorbing box is squeezed and deformed, thereby completing the absorption of the impact load.

[0029] Example 2: This embodiment is an improvement based on Embodiment 1.

[0030] When the energy-absorbing box connects the protective parts 11 on both sides, the energy-absorbing box is fixed by bolt connection or welding. When connected by bolt, there are two situations in the direction of the bolt. Specifically, the bolt used here is a positioning bolt 121. First, the positioning bolt 121 is perpendicular to the first direction X. When the protective frame 1 is impacted, when the impact load is transmitted to the positioning bolt 121, the positioning bolt 121 is subjected to shear force, which can easily cause damage to the positioning bolt 121. The second type, such as Figure 2 and Figure 3As shown, the positioning bolt 121 is arranged along the first direction X. The end wall of the energy-absorbing box abuts against the end wall of the protective part 11. The positioning bolt 121 passes through the energy-absorbing box and is threadedly connected to the protective part 11. When the protective frame 1 is subjected to an impact load in the first direction X, the risk of damage to the positioning bolt 121 caused by the impact load can be reduced.

[0031] Furthermore, in this application, as Figure 1 As shown, the protective frame 1 has a rectangular design and is distributed at the corners of the inner cavity of the distribution box to enhance the strength of the distribution box.

[0032] Among them, such as Figure 2 and Figure 4 As shown, the protective part 11 includes a frame 110 that is connected end to end in a closed rectangle and a plurality of support rods 111. In this application, four sets of support rods 111 are provided. The plane where the frame 110 is located is perpendicular to the first direction X. The support rods 111 are fixedly installed on the frame 110 and extend along the first direction X toward the buffer part 12, so that the buffer part 12 is fixedly installed on the support rods 111.

[0033] It is worth noting that when the support rod 111 is installed on the frame 110, the end wall of the support rod 111 abuts against the side wall of the frame 110 near the buffer part 12.

[0034] When the protective frame 1 is subjected to an impact load in the first direction X, the load is first applied to the frame 110, and then the support rod 111 is pushed along the first direction X by the side wall of the frame 110, thereby compressing the buffer part 12. During this process, the impact process is reduced. The frame 110 and the support rod 111 are misaligned, which causes the support rod 111 to protrude outward.

[0035] To achieve the composition of the border 110, in this embodiment, as follows: Figure 4 and Figure 5 As shown, the frame 110 includes two first pillars 1101 distributed along the second direction Y, wherein the first pillars 1101 extend along the third direction Z, and also includes two angle irons 1102 distributed along the third direction Z, wherein the angle irons 1102 extend along the second direction Y, and the two angle irons 1102 are respectively set at both ends of the first pillars 1101, thereby realizing the composition of the frame 110. It is worth noting that the first pillars 1101 and the angle irons 1102 are welded together.

[0036] Furthermore, the cross-section of angle iron 1102 is L-shaped.

[0037] like Figure 4 and Figure 5As shown, both ends of the first support column 1101 are provided with a first locking interface 11011 facing the buffer part 12. The end of the support rod 111 away from the buffer part 12 is provided with a second locking interface 1111 that is compatible with the first locking interface 11011. When the support rod 111 is installed with the first support column 1101, the first locking interface 11011 and the second locking interface 1111 are engaged. At this time, the end wall of the support rod 111 away from the buffer part 12 abuts against the inner wall of the first locking interface 11011, thereby reducing the risk of the support rod 111 penetrating the first support column 1101.

[0038] At this time, as Figure 5 As shown, the two sides of the angle iron 1102 are welded to the support rod 111 and the first support column 1101, respectively.

[0039] To reduce the risk of misalignment between the support rod 111 and the first pillar 1101 after the protective frame 1 is impacted in the second direction Y, such as Figure 4 and Figure 6 As shown, a limiting baffle 1103 is welded onto the angle iron 1102. When the angle iron 1102 is installed between the two first pillars 1101 of the protective part 11, the limiting baffle 1103 abuts against the side wall of the support rod 111 and the first pillar 1101, thereby solving the problem of misalignment of the support rod 111 and the first pillar 1101 after being impacted by the second direction Y.

[0040] In this embodiment, as Figure 1 and Figure 7 As shown, it also includes a support plate 4, which is bolted to any set of protective parts 11. The support plate 4 is located in the inner cavity of the space enclosed by the protective frame 1, and the components are mounted on the support plate 4.

[0041] like Figure 7 As shown and Figure 8 As shown, the protective part 11 has two first support columns 1101 with insertion slots 1104 on the same horizontal plane, and also includes a reinforcing tube 2 arranged along the second direction Y. The reinforcing tube 2 is located between the two first support columns 1101, and both ends of the reinforcing tube 2 are respectively inserted into the insertion slots 1104. The reinforcing tube 2 and the first support column 1101 are riveted together by rivets 3, thereby fixing the reinforcing tube 2 and the first support column 1101.

[0042] like Figure 9 As shown, at this time, the end wall of the reinforcing tube 2 abuts against the inner wall of the insertion groove 1104, supporting the two first pillars 1101, thus solving the problem that after the first pillar 1101 is subjected to an impact load in the second direction Y, it moves along the second direction Y and hits the components on the bearing plate 4.

[0043] Example 3: This embodiment discloses a distribution box, such as Figure 10 As shown, the distribution box here is an improvement based on Embodiment 2.

[0044] Specifically, the distribution box is enclosed by sheet metal 5 to form a box body with an opening on one side. The opening of the box body is the front side of the distribution box, and a door is hinged to the opening. The hinge between the door and the box body is a conventional design, so the structure of the door is not shown in the figure. Furthermore, the sheet metal 5 is enclosed on the outside of the protective frame 1. The first pillar 1101 and the support rod 111 on the protective frame 1 support the joints between the surfaces of the distribution box, thereby strengthening the distribution box.

[0045] The support plate 4 is set on the protective part 11 on the side away from the box opening. When the box door is impacted by the first direction X, the protective part 11 on the side near the box door will squeeze the energy-absorbing box of the buffer part 12 along the first direction X. The energy-absorbing box absorbs the energy of the impact load. At this time, the components are installed on the protective part 11 on the side away from the box opening through the support plate 4. Compared with the prior art, the risk of damage to the components caused by the compression of the box body is reduced.

[0046] If a support rod is installed inside a conventional distribution box along the first direction X, under normal circumstances, the support rod is aligned with the width direction of the distribution box. When the distribution box is impacted by the first direction X, the support rod is likely to pierce the sheet metal 5 of the distribution box, which could easily injure workers or cause serious safety accidents.

[0047] In this application, the end wall of the support rod 111 abuts against the end wall of the frame 110 near the buffer part 12, and the frame 110 bears the piercing force of the support rod 111, reducing the risk of the sheet metal 5 of the distribution box being pierced.

[0048] It is worth noting that the design of angle iron 1102 here, such as Figure 5 As shown, angle iron 1102 can further reduce the risk of support rod 111 penetrating sheet metal 5.

[0049] When the distribution box is subjected to an impact load in the second direction Y, the protective part 11 located on the side of the distribution box opening is equipped with a limiting baffle 1103 inside the angle iron 1102, which can reduce the relative displacement of the two first pillars 1101 on the same protective part 11 in the second direction Y.

[0050] The two first pillars 1101 of the protective part 11 on the side away from the opening of the distribution box are supported by the reinforcing tube 2. When subjected to the impact load in the second direction Y, the protective part 11 and the bearing plate 4 at this point can be pushed to move along the second direction Y as a whole, thereby reducing the risk of damage to the components.

[0051] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. For example, the steps described in this disclosure can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution disclosed in this application can be achieved, and this is not limited herein.

[0052] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0053] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
