Description

Technical Field

[0001] This utility model relates to the field of container sealing and protection technology, specifically to a protective component and a container. Background Technology

[0002] In the field of container door frame structure protection, especially for industrial containers involving frequent cargo handling, such as energy storage containers, the edges of the door frame are highly susceptible to damage when the door is open. Whether the door frame has a sealing strip or not, its edges may come into direct contact and collide with goods or transport equipment during loading and unloading using forklifts or other transport vehicles. For door frames with sealing strips, the sealing strip, especially the edge near the door hinge, is particularly vulnerable when the door is open for cargo handling. When forklifts transport goods, the edges of the goods are easily scratched and squeezed against the sealing strip, causing it to wear, tear, or even fall off. This not only affects the sealing effect and reduces the protection level but also increases maintenance costs. For door frames without sealing strips, the exposed edges also face the risk of deformation, coating damage, and even structural damage due to scratches and collisions, affecting the flatness, aesthetics, and service life of the door frame. Current technologies lack adequate protective measures for door frame edges. Some solutions may involve complex installation structures or permanent modifications to the door frame itself (such as drilling holes to install protective panels), which not only increases costs but may also compromise the original structural integrity and protective performance of the door frame. There is a lack of a simple, universal, non-invasive, and easily removable protective solution to effectively protect the edges of various types of door frames from damage during operation. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned defects or problems in the background art and to provide a protective component and a container. The protective component can be easily installed on the door frame and provides effective protection for the vulnerable areas of the door frame when needed.

[0004] To achieve the above objectives, the various embodiments of this utility model adopt the following technical solutions, but are not limited to the following solutions:

[0005] The first technical solution relates to a protective component for protecting a vulnerable area of ​​a door frame when the door is open. The door frame includes a front wall and a protrusion extending forward from the front wall, with the front wall exposed between the door hinge and the protrusion. The vulnerable area is at least a portion of the protrusion's horizontal side closest to the door hinge along the vertical direction. The protective component extends vertically and includes a connecting wall, a protective wall, and a fixing member. The connecting wall is adapted to fit against the front wall located between the door hinge and the protrusion. The protective wall is integral with the connecting wall and adapted to cover the vulnerable area. The fixing member is fixed to the connecting wall so that the connecting wall is detachably connected to the front wall.

[0006] The second technical solution is based on the first technical solution, wherein a sealing strip is fixedly attached to the protruding part of the door frame, and the vulnerable area is at least a portion of the sealing strip along the horizontal direction near the door hinge and along the vertical direction; the protective wall is a U-shaped structure, suitable for covering the vulnerable area of ​​the sealing strip.

[0007] The third technical solution is based on the second technical solution, wherein the opening width of the protective wall is greater than the thickness of the protrusion, forming a buffer space to accommodate the sealing strip.

[0008] The fourth technical solution is based on the first technical solution, wherein the fastener is made of magnetic material, and there are several fasteners arranged at intervals along the extension direction of the connecting wall, and the position of the door frame corresponding to the fastener is a magnetic metal area.

[0009] The fifth technical solution is based on the fourth technical solution, wherein the fastener is fixed to the back side of the connecting wall by countersunk screws, and the head of the countersunk screws is sunk into the inner surface of the connecting wall.

[0010] The sixth technical solution is based on the fourth technical solution, wherein the fastener is embedded inside the connecting wall and the adsorption surface of the fastener is flush with the surface of the connecting wall.

[0011] The seventh technical solution is based on the fourth technical solution, wherein the connecting wall is provided with an outwardly protruding handle, and the handle is located in the interval area between adjacent fasteners.

[0012] The eighth technical solution is based on the second technical solution, wherein the protective wall covers the entire vulnerable section of the sealing strip.

[0013] The ninth technical solution is based on the first technical solution, wherein the protective wall fitting protrusion is provided with a clearance opening on the side facing the door frame opening, the protrusion is provided with a protrusion protruding above its surface, and the width of the clearance opening matches the protrusion.

[0014] The tenth technical solution is based on any one of the first to ninth technical solutions, a container comprising at least two parallel door frames, wherein the door frames include at least one of the aforementioned protective elements.

[0015] As can be seen from the above description of the various embodiments of the present utility model, compared with the prior art, the various embodiments of the present utility model have the following beneficial effects:

[0016] In the first technical solution and related embodiments, a universal door frame protection component is provided. Through a detachable fixing method, without damaging the door frame structure (e.g., by drilling), a physical barrier is provided for the most vulnerable edge area of ​​the protruding part of the door frame (near the door hinge side), effectively preventing structural damage or deformation of the door frame caused by forklift or cargo collisions when the door is open. The connecting wall increases the contact area between the protection component and the front wall of the door frame to facilitate the installation of fixing components.

[0017] In the second technical solution and related embodiments, in the common application scenario of door frames with sealing strips, the container has a high level of protection. Through its U-shaped protective wall structure, it can wrap and protect the sealing strip, preventing it from being scratched, worn or cut. While providing physical protection, it ensures that the container's sealing performance and protection level are not affected.

[0018] In the third technical solution and related embodiments, the buffer space can accommodate the sealing strip and allow it to undergo slight deformation when compressed, thus avoiding excessive compression of the sealing strip when the protective wall is installed or subjected to pressure.

[0019] In the fourth technical solution and related embodiments, the fasteners are arranged at intervals along the connecting wall to enhance the adsorption stability between the protective components and the front wall of the door frame and prevent the protective components from falling off due to transportation vibration; the fasteners are made of magnetic materials to achieve non-destructive installation and meet the protection level requirements for non-penetrating installation.

[0020] In the fifth technical solution and related embodiments, the fastener is fixed by countersunk screws, with the screw heads sunk into the inner surface of the connecting wall, eliminating the sealing hazards caused by drilling in the door frame body and maintaining the overall protection level.

[0021] In the sixth technical solution and related embodiments, one embodiment is that the fastener is embedded inside the connecting wall, avoiding the use of screws and eliminating the influence of the protruding structure on the sealing performance.

[0022] In the seventh technical solution and related embodiments, the handle is designed to be staggered, which facilitates the quick and easy disassembly of the protective component by hand, while avoiding interference with the adsorption function of the fixing component during the operation of the handle.

[0023] In the eighth technical solution and related embodiments, the protective wall covers the entire vulnerable area, achieving full vertical protection.

[0024] In the ninth technical solution and related embodiments, the avoidance opening design prevents the protective component from interfering with the protruding component (such as a metal sheet) on the inner side of the door frame, ensuring installation compatibility.

[0025] In the tenth technical solution and related embodiments, this protective component is installed on multiple door frames throughout the container, thereby providing a systematic and unified protection solution for the vulnerable areas of all door frames of the entire container body. This container uses this protective component to reduce wear and tear on the door frames or sealing strips caused by frequent loading and unloading on the battery transport channel side, specifically addressing the special working conditions (such as high-frequency friction) of the battery transport channel side.

[0039] In the claims, description and accompanying drawings of this utility model, the terms "comprising", "having", and variations thereof are used to mean "including but not limited to".

[0040] See Figures 1 to 6 ,like Figure 1 and Figure 2 As shown, a protective element 2 is used to protect the vulnerable area of ​​a door frame 1 when the door is open. The door frame 1 has an opening 12 and includes a front wall 13 and a protrusion 14 extending forward from the front wall. The front wall 13 is exposed between the door hinge 11 and the protrusion 14. The vulnerable area is at least a portion of the protrusion 14 along the horizontal direction near the side of the door hinge 11 along the vertical direction.

[0041] In this embodiment, a sealing strip 3 is fixedly attached to the protrusion 14 of the door frame 1. The vulnerable area is at least a portion of the sealing strip 3 along the horizontal direction near the side of the door hinge 11 and along the vertical direction. The container in this embodiment is an energy storage container. The door frame of the energy storage container is sealed by setting a high-efficiency sealing strip, and its protection level (such as IP54 and above) is crucial to the safe operation of the internal battery system. During the forklift transportation of the battery rack unit, the edge of the battery comes into direct contact with the sealing strips 3 on both sides of the door frame 1. Frequent friction can easily cause the sealing strips 3 to wear or be cut, damaging the sealing structure.

[0042] Specifically, such as Figure 4 As shown, the door frame 1 is vertically installed at the end of the container opening 12, and its front wall 13 extends horizontally. The door hinge 11 is located on one side edge of the door frame 1. An exposed area is formed between the front wall 13 and the door hinge 11, which is not covered by the door panel.

[0043] The front end of the front wall 13 extends forward to form a protrusion 14. The outer side of the protrusion 14 is fixed with a sealing strip 3 by a slot. The vulnerable area of ​​the sealing strip 3 is located in the entire vertical section of its side near the door hinge 11 in the horizontal direction.

[0044] When the battery rack unit is loaded into the container by a forklift, the edge of the battery moves perpendicular to the door frame 1, which can easily cause friction with the vulnerable area of ​​the sealing strip 3.

[0045] A protective component 2 extends vertically, wraps around the left and right sides of the door frame 1, and covers the exposed surface of the sealing strip 3. The protective component 2 includes a connecting wall 22, a protective wall 23, and a fixing component 21.

[0046] Specifically, such as Figures 3 to 6 As shown, the main body of the protective component 2 is a U-shaped structural component integrally stamped from aluminum-zinc coated steel sheet, including a protective wall 23 and a connecting wall 22. The aluminum-zinc coated steel sheet material has both corrosion resistance and impact resistance, extending the service life of the protective component 2.

[0047] The connecting wall 22 is adapted to fit against the front wall 13 located between the door hinge 11 and the protrusion 14. Specifically, the connecting wall 22 is a vertically extending flat plate structure, the width of which matches the exposed area of ​​the front wall 13 of the door frame 1, and the rear surface is adsorbed onto the front wall 13 by a fastener 21. Specifically, the connecting wall 22 is a protective wall 23 extending towards the front wall 13 of the door frame 1 to form a horizontally bent flange. The connecting wall 22 has a certain width, and the fitting surface forms a surface contact with the frame wall.

[0048] like Figure 3 and Figure 5 As shown, a protruding handle 24 is stamped outward on the outer side of the connecting wall 22. The handle 24 has a U-shaped structure and is located in the area between adjacent fasteners 21. During operation, applying force to the handle 24 can overcome the magnetic attraction and disassemble the protective component 2. The staggered design of the handle 24 facilitates manual and quick disassembly of the protective component 2, while avoiding interference with the adsorption function of the fastener 21 during the operation of the handle 24.

[0049] The protective wall 23 is integrated with the connecting wall 22 and is suitable for covering vulnerable areas. Specifically, the protective wall 23 and the connecting wall 22 are vertically connected to form a U-shaped groove structure with the opening 12 facing outward. The width of the opening 12 of the protective wall 23 is greater than the thickness of the protrusion 14, forming a buffer space for the sealing strip 3, which can accommodate the sealing strip 3 and allow it to undergo slight deformation under pressure.

[0050] The protective wall 23 covers the entire vulnerable section of the sealing strip 3, ensuring that the battery edge does not directly contact the strip.

[0051] The protective wall 23 has a clearance 25 on the side of the protrusion 14 facing the opening 12 of the door frame 1, and the width of the clearance 25 matches the protrusion 15 on the protrusion 14. Specifically, the protective wall 23 fits the protrusion 14 and is in close contact with the lateral surface of the protrusion 14 to ensure a gapless fit. On the side of the protrusion 14 facing the opening 12 of the door frame 1, there are some protrusions 15, such as metal pieces. The clearance 25 is designed to prevent interference between the protective wall 2 and the protrusions 15.

[0052] Fastener 21, such as Figure 4 and Figure 6 As shown, it is fixed to the connecting wall 22 so that the connecting wall 22 can be detachably connected to the front wall 13. Specifically, there are several fasteners 21, which are arranged at intervals along the vertical extension direction of the connecting wall 22 to enhance the adsorption stability between the protective member 2 and the front wall 13 of the door frame 1 and prevent the protective member 2 from falling off due to transportation vibration.

[0053] Specifically, the fastener 21 is made of magnetic material, and the position of the door frame 1 corresponding to the fastener 21 is a magnetically conductive metal area. In this embodiment, the fastener 21 is a magnet, which can be a neodymium iron boron magnet, with its adsorption surface facing the magnetically conductive area on the front wall 13. The frame wall is made of metal, and the corresponding position is the magnetically conductive metal area. If a special coating is used on the steel, the magnetically conductive area is the area where the special coating has been removed. The magnet is aligned with the magnetically conductive area, and the magnetic attraction directly acts on the magnetically conductive material (such as steel) of the door frame 1, improving the adsorption stability.

[0054] There are two ways to connect the fastener 21 to the connecting wall 22.

[0055] Example 1

[0056] The fastener 21 is fixed to the connecting wall 22 by countersunk screws 26. Specifically, the fastener 21 is fixed to the back side of the connecting wall 22 by M4 countersunk screws 26, with the screw head recessed into the inner surface of the connecting wall 22 to avoid compressing the sealing strip 3. In this embodiment, this connection method eliminates the sealing hazard caused by drilling into the door frame 1 body, maintaining the overall protection level.

[0057] Example 2

[0058] The connecting wall 22 is fitted with an embedded fastener 21. Specifically, the fastener 21 is directly embedded in the reserved groove of the connecting wall 22, and its adsorption surface is flush with the surface of the connecting wall 22, eliminating the influence of the protruding structure on the sealing performance.

[0059] The specific installation steps are as follows:

[0060] Align the protective wall 23 of the protective component 2 with the protrusion 14, so that the buffer space is wrapped with the sealing strip 3; push the connecting wall 22 to fit against the front wall 13, and the fixing component 21 will automatically be adsorbed and positioned; check whether the clearance 25 avoids the locking rod fixing component, and the installation is completed.

[0061] Working principle of protective component 2:

[0062] Physical isolation: When the edge of the battery moves vertically, it first contacts the outer surface of the protective wall 23, and absorbs the impact energy through the buffer space, avoiding direct force on the sealing strip 3;

[0063] Magnetic maintenance: When maintenance is required, the protective component 2 can be quickly removed by manually pulling the handle 24 without damaging the door frame 1 structure.

[0064] In this embodiment, the protective component 2 covers the vulnerable area of ​​the sealing strip 3 through the protective wall 23, physically isolating the battery edge from direct contact with the strip and avoiding wear or tear of the strip due to transportation friction; the protective component 2 is detachable and can be quickly disassembled and assembled without damaging the structure of the door frame 1; the connecting wall 22 increases the contact area between the protective component 2 and the front wall 13 of the door frame 1 to facilitate the installation of the fastener 21, which enables non-destructive installation and meets the IP54 protection level requirements for non-penetrating installation.

[0065] A type of container, such as Figure 1 and Figure 2 As shown, the device includes at least two parallel door frames 1, each door frame 1 containing at least one of the aforementioned protective elements 2, and the protective element 2 extending to cover the operating side of the protrusion 14 of the door frame 1. Specifically, two protective elements 2 are installed on the battery transport channel side (near the door hinge 11) to form double protection.

[0066] The container can be an energy storage container, with the operating side of its door frame 1 being the battery transport channel side. In this embodiment, the container uses the protective component 2 to reduce the wear of the rubber strips on the battery transport channel side due to frequent loading and unloading, addressing the special working conditions (such as high-frequency friction) in this area and solving the problem of wear and failure of the sealing rubber strips 3 in this area.

[0067] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
