[0002] Protective vehicles are generally built on the basis of ordinary vehicles, achieving their protective function by adding bulletproof structures to the body. To achieve bulletproof protection for the vehicle doors, bulletproof steel plates need to be added. However, due to the limited space inside the door, the complex curved structure of the door, and the fact that the added bulletproof steel plates, within the required thickness, can only be shaped by bending, making it difficult to adapt to the curved structure of the door, the bulletproof steel plates can only be installed by welding them externally without major modifications to the door. This results in a complex connection between the bulletproof steel plates and the door, requiring multiple welding operations and sacrificing the door's aesthetic appearance. Utility Model Content

Detailed Implementation

[0029] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0030] In this disclosure, unless otherwise stated, directional terms such as "upper," "lower," "higher," "lower," "top," and "bottom" generally refer to the orientation of the corresponding component or structure in the direction of gravity. "Inner" and "outer" refer to the inner and outer contours of the corresponding component. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not indicate sequence or importance. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same element. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0031] This disclosure relates to a door assembly that can be used in protective vehicles, providing both good bulletproof capabilities and a more aesthetically pleasing appearance, while also facilitating maintenance. See also Figure 1 The door assembly disclosed herein includes a door panel structure 1 and a bulletproof structure 2. The door panel structure 1 includes an inner door panel 11 and an outer door panel 12. The inner door panel 11 and the outer door panel 12 are mostly made of metal materials to give them high strength. The bulletproof structure 2 is located between the inner door panel 11 and the outer door panel 12 to give the door panel structure 1 good bulletproof function. The bulletproof structure 2 includes bulletproof fiber 21 and bulletproof plate 22. The bulletproof fiber 21 can be made of materials such as aramid fiber and ultra-high molecular weight polyethylene. While having bulletproof function, it is also relatively soft and can adapt to the relatively complex curved surface structure on the inner door panel 11 and the outer door panel 12. The bulletproof plate 22 can be made of materials such as composite steel plate and stainless steel plate. It has high hardness and stronger bulletproof performance, but can only change its shape by bending.

[0032] When installing the bulletproof structure 2 and the door panel structure 1, the shape of the bulletproof fiber 21 on the side close to the door panel 12 can be processed to match the curved surface structure of the door panel 12, and the shape on the side away from the door panel 12 can be processed to match the surface structure of the bulletproof plate 22, based on the curved surface structure of the outer door panel 12 and the surface structure of the bulletproof plate 22. Then, the bulletproof fiber 21 can be connected to the outer door panel 12 so that the bulletproof fiber 21 can be fitted to the outer door panel 12. After connecting the bulletproof fiber 21 to the outer door panel 12, the bulletproof plate 22 can be connected to the side of the bulletproof fiber 21 away from the outer door panel 12 so that the bulletproof plate 22 can also be fitted to the bulletproof fiber 21. Finally, the inner door panel 11 can be connected to the outer door panel 12 to complete the installation between the bulletproof structure 2 and the door panel structure 1.

[0033] The disclosed door assembly provides a base for the installation of a bulletproof fiber 21 between the inner door panel 11 and the outer door panel 12. Since the bulletproof fiber 21 can be shaped differently on both sides according to the curved surface of the outer door panel 12 and the surface structure of the bulletproof plate 22, both sides of the bulletproof fiber 21 can be fitted to the inner door panel 12 and the bulletproof plate 22 respectively. This design takes into account the curved surface of the outer door panel 12, ensuring its aesthetic appearance and allowing the outer door panel 12 to be connected to the bulletproof plate 22 without major modifications. Furthermore, the fitted arrangement of the bulletproof fiber 21 and the bulletproof plate 22 makes the connection between them more convenient and secure.

[0034] In one embodiment of this disclosure, see Figure 1 The bulletproof fiber 21 has a curved profile on the side of the outer door panel 12, consisting of at least two arcs. Since the profile of the outer door panel 12 is usually composed of multiple curves, these multiple curves can ensure the appearance of the outer door panel 12, as well as its durability and impact resistance during use. In order to facilitate its fit with the outer door panel 12, the side of the bulletproof fiber 21 near the outer door panel 12 needs to be designed to be curved and consist of at least two curves. The specific number of curve segments and the connection method between the curves can be determined according to the profile of the outer door panel 12, and this disclosure does not impose any restrictions on this.

[0035] The bulletproof fiber 21 has a zigzag outline on the side of the outer door panel 12 away from the door, consisting of at least two straight lines. Since the bulletproof plate 22 is mostly made of hard metal plates, it can only be bent to change its shape to a certain extent during processing to facilitate installation. The bulletproof fiber 21 has a zigzag outline on the side of the outer door panel 12 away from the door, and consists of at least two straight lines, which allows it to fit better with the bulletproof plate 22 and facilitates the fixed connection between the bulletproof plate 22 and the bulletproof fiber 21. The specific number of straight lines included in the bulletproof fiber 21 and the connection method between the straight lines can be determined according to the outline of the bulletproof plate 22, and this disclosure does not impose any restrictions on this.

[0036] In one embodiment of this disclosure, see Figure 1 and Figure 2The inner door panel 11 includes an inner body panel 111, the outer door panel 12 includes an outer body panel 121, the bulletproof plate 22 includes a body bulletproof plate 221, and the bulletproof fiber 21 includes a body bulletproof fiber 211. The body portion of the door assembly can be the lower part of the door assembly relative to the vertical direction, and its shape is mostly approximately rectangular. The body bulletproof fiber 211 and body bulletproof plate 221 are connected to the inner body panel 111 and the outer body panel 121 in the following way: one side of the body bulletproof fiber 211 is attached to and fixedly connected to the outer body panel 121, and the body bulletproof plate 221 is attached to and fixedly connected to the other side of the body bulletproof fiber 211, so that the body bulletproof plate 221 can be better connected to the outer body panel 121 through the body bulletproof fiber 211 while maintaining the appearance of the outer body panel 121.

[0037] In one embodiment of this disclosure, see Figure 1 and Figure 2 The body-mounted bulletproof fiber 211 is ring-shaped. The outer ring of the body-mounted bulletproof fiber 211 is fixedly connected to the outer body panel 121, and the inner ring is fixedly connected to the body-mounted bulletproof plate 221. By setting the body-mounted bulletproof fiber 211 as a ring, the area relationship between the body-mounted bulletproof fiber 211 and the body-mounted bulletproof plate 221 can be adjusted according to the bulletproof requirements of the door during the manufacturing process of the body-mounted bulletproof fiber 211. For example, in doors with lower bulletproof requirements, the area of ​​the body-mounted bulletproof fiber 211 can be appropriately increased, that is, the length of the inner ring of the body-mounted bulletproof fiber 211 and the area of ​​the body-mounted bulletproof plate 221 connected to the inner ring of the body-mounted bulletproof fiber 211 can be reduced, thereby reducing the cost and manufacturing difficulty of the door assembly to a certain extent. In doors with lower bulletproof requirements, the area of ​​the body-mounted bulletproof fiber 211 can be appropriately reduced, that is, the length of the inner ring of the body-mounted bulletproof fiber 211 and the area of ​​the body-mounted bulletproof plate 221 connected to the inner ring of the body-mounted bulletproof fiber 211 can be increased, so as to ensure the bulletproof strength of the body part in the door assembly.

[0038] In one embodiment of this disclosure, see Figure 1 and Figure 2 Multiple first connecting holes 23 are provided along the inner circle of the body bulletproof fiber 211 and the edge of the body bulletproof plate 221. The multiple first connecting holes 23 can be evenly arranged along the inner circle of the body bulletproof fiber 211 and the edge of the body bulletproof plate 221. The first connecting holes 23 can cooperate with the first connector 24 to fix the body bulletproof fiber 211 and the body bulletproof plate 221.

[0039] For example, in some embodiments, the first connecting hole 23 can be a threaded hole, and the first connecting member 24 can include a bolt and a nut. When connecting the body bulletproof fiber 211 and the body bulletproof plate 221, the head of the bolt can be fixed to the body bulletproof fiber 211, and then the threaded hole on the body bulletproof plate 221 can be passed through the end of the bolt. Finally, the body bulletproof plate 221 can be fixed to the body bulletproof fiber 211 with a nut. Connecting the body bulletproof fiber 211 and the body bulletproof plate 221 in the above manner is easier than the traditional welding method, and it is easier to disassemble them during subsequent maintenance, thereby improving maintenance efficiency. Of course, in other embodiments, the fixed connection between the body bulletproof fiber 211 and the body bulletproof plate 221 can also be other, such as direct bonding. The specific method can be determined according to the actual situation, and this disclosure does not limit it.

[0040] In one embodiment of this disclosure, see Figure 1 and Figure 2 The inner body panel 111 and the outer body panel 121 are fixedly connected to form a first receiving cavity 13 between the inner body panel 111 and the outer body panel 121, which can accommodate the body bulletproof plate 221 and the body bulletproof fiber 211. After the body bulletproof plate 221 is connected to the body bulletproof fiber 211, the body bulletproof plate 221 and the body outer panel 121 are spaced apart. The first receiving cavity 13 can be formed by the body outer panel 121 protruding in a direction away from the body. By setting the first receiving cavity 13, the body bulletproof plate 221 can be spaced apart from the body outer panel 121 after being connected to the body bulletproof fiber 211, so as to avoid interference between the body bulletproof plate 221 and the door outer panel 121, which would cause damage to the door outer panel 121.

[0041] In one embodiment of this disclosure, see Figure 1 and Figure 2 The inner body panel 111 and the outer body panel 121 are fixedly connected by the edge of the outer body panel 121 wrapping around the edge of the inner body panel 111. This wrapping can be done using existing edge-binding methods. The body's bulletproof fiber 211 is located between the edges of the outer body panel 121 and the inner body panel 111, allowing the bulletproof fiber 211 to be clamped between the inner body panel 111 and the outer body panel 121, thus completing the fixed connection between the bulletproof fiber 211 and the inner and outer body panels 111. This connection ensures a tight bond between the bulletproof fiber 211 and the inner and outer body panels 111, preventing loosening and ensuring connection stability, thus reducing the likelihood of loosening during vehicle operation.

[0042] In one embodiment of this disclosure, see Figure 1 and Figure 3Multiple opposing second connecting holes 14 are provided along the edges of the inner body panel 111 and the outer body panel 121. The multiple second connecting holes 14 can be evenly arranged along the edging edges of the inner body panel 111 and the outer body panel 121. The second connecting holes 14 can cooperate with the second connecting member 15 to fix the outer body panel 121 and the inner body panel 111. The body bulletproof fiber 211 is located between the inner body panel 111 and the outer body panel 121. The second connecting member 15 can also clamp the body bulletproof fiber 211 between the inner body panel 111 and the outer body panel 121 to complete the connection between the body bulletproof fiber 211 and the inner body panel 111 and the outer body panel 121.

[0043] For example, in some embodiments, the second connecting hole 14 can be a threaded hole, and the second connecting member 15 can include a bolt and a nut. When connecting the inner body panel 111 and the outer body panel 121, the head of the bolt can be fixed to the body bulletproof fiber 211. Then, the threaded holes on the edges of the inner body panel 111 and the outer body panel 121 are passed through the ends of the bolts. Finally, the inner body panel 111 and the outer body panel 121 are fixed to the body bulletproof fiber 211 by the nut. The connection of the inner body panel 111, the outer body panel 121 and the body bulletproof fiber 211 in the above manner is more convenient for disassembly during subsequent maintenance than the traditional welding method, thereby improving maintenance efficiency. Of course, in other embodiments, the fixed connection between the inner body panel 111, the outer body panel 121 and the body bulletproof fiber 211 can also be other, depending on the actual situation. This disclosure does not limit this.

[0044] In one embodiment of this disclosure, see Figure 1 and Figure 4 The inner door panel 11 includes an inner window panel 112, the outer door panel 12 includes an outer window panel 122, the bulletproof plate 22 includes a bulletproof window plate 222, and the bulletproof fiber 21 includes a bulletproof window fiber 212. The window portion of the door assembly can be the upper part of the door assembly relative to the vertical direction, and its shape is often an approximately rectangular ring. Bulletproof glass can be installed on the inner ring of this ring. The connection between the bulletproof window fiber 212 and the bulletproof window plate 222 and the inner window panel 112 and outer window panel 122 is such that the shape of the bulletproof window fiber 212 can be adapted to the outer window panel 112; for example, if the outer window panel 112 is rectangular, then the bulletproof window fiber 212 is also rectangular.

[0045] During connection, the side of the bulletproof fiber 212 near the outer window panel 122 is fitted and fixedly connected to the outer window panel 122, and one side of the bulletproof plate 222 is fitted and fixedly connected to the other side of the bulletproof fiber 212, while the other side abuts against the inner window panel 112. Since bulletproof glass is installed in both the outer window panel 122 and the inner window panel 112, the locations of the bulletproof glass on the outer window panel 122 and the inner window panel 112, as well as the edges where the two panels fit together, typically require specific positioning. The U-shaped groove 17 is provided so that when bullets fly laterally from different angles through the outer window panel 122 and the inner window panel 112 towards the U-shaped groove 17 of the window, the bulletproof plate 222 of the window, which is only attached to the bulletproof fiber 212 of the window, is difficult to stop the bullets. However, when one side of the bulletproof plate 222 of the window is fixedly connected to the bulletproof fiber 212 of the window and the other side abuts against the inner window panel 112, the part located between the outer window panel 122 and the inner window panel 112 can effectively block the bullets flying towards the window from the U-shaped groove 17.

[0046] In one embodiment of this disclosure, see Figure 1 and Figure 4 The outer window panel 122 is fixedly connected to the inner window panel 112. A second receiving cavity 16 is provided on the inner window panel 112, extending away from the inner window panel 112. The bulletproof window plate 222 extends in the same direction as the second receiving cavity 16, and can accommodate the bulletproof window plate 222 and the bulletproof window fiber 212. During connection, the bulletproof window fiber 212 can be fixedly connected to the outer window panel 122 first, then one end of the bulletproof window plate 222 can be connected to the bulletproof window fiber 212, and then the outer window panel 122 can be connected to the inner window panel 112, so that the other end of the bulletproof window plate 222 is inserted into the second receiving cavity 16 and abuts against the bottom of the second receiving cavity 16 in the extending direction, so that the bulletproof window plate 222 located between the bulletproof window fiber 212 and the bottom of the second receiving cavity 16 can effectively block bullets flying towards the window from the U-shaped groove 17.

[0047] Of course, in other embodiments, the connection method and structure between the bulletproof fiber 212 and the bulletproof plate 222 of the window and the outer panel 122 and the inner panel 112 of the window can also be of other types, as long as the bulletproof plate 222 of the window can effectively block the bullets flying towards the window from the U-shaped groove 17. The specific method can be determined according to the actual situation, and this disclosure does not limit it.

[0048] In one embodiment of this disclosure, see Figure 1 and Figure 4The second receiving cavity 16 is located between the outer window panel 122 and the inner window panel 112 near the edge of the window and away from the edge of the window. This arrangement ensures that the bulletproof plate 222 located between the bulletproof fiber 212 and the bottom of the second receiving cavity 16 can effectively block bullets flying towards the window from the U-shaped groove 17 where the bulletproof glass is positioned on the outer window panel 122 and the inner window panel 112, as well as from the U-shaped groove 17 at the edge where the outer window panel 122 and the inner window panel 112 meet. In some embodiments, the second receiving cavity 16 can also be located at the midpoint between the edge near the window and the edge away from the window, thereby better preventing bullets flying towards the window from the U-shaped groove 17 at both edge positions.

[0049] In one embodiment of this disclosure, see Figure 1 and Figure 4 The second receiving cavity 16 can be perpendicular to the inner window panel 112, so that the bulletproof window plate 222 is also perpendicular to the inner window panel 112. This arrangement, compared to other angles between the bulletproof window plate 222 and the inner window panel 112, allows for blocking bullets flying at more angles towards the window with the shortest possible bulletproof window plate 222, saving material in manufacturing the bulletproof window plate 222 and reducing the cost of manufacturing the door assembly. See also the following embodiments. Figure 4 A slot 213 is also provided on the bulletproof fiber 212 of the window. One end of the bulletproof plate 222 of the window can be inserted into the slot 213 through the slot 213 to complete the fixed connection between the end of the bulletproof plate 222 of the window and the bulletproof fiber 212 of the window. The fixed connection can be fixed by adhesive or other fixing methods known to those skilled in the art, which will not be described in detail here.

[0050] When connecting the door assembly disclosed herein, the bulletproof structures 2 of the body and window portions in the door panel structure 1 can be connected separately. The connection relationship and steps between the bulletproof structure 2 and the body and window portions can be found in the description of the above embodiments, and will not be repeated here. By setting different types of bulletproof structures 2 in the body and window portions respectively, the bulletproof effect can be better achieved, such as blocking bullets flying towards the window from the side. Different body bulletproof fibers 211 and body bulletproof plates 221 can be designed according to actual conditions, and the stability of the connection between the bulletproof plate 22 and the outer door panel 12 can be ensured without affecting the appearance of the door assembly.

[0051] A second aspect of this disclosure also provides a vehicle including at least one door assembly as described in the above embodiments. By using the door assembly of this disclosure, the connection stability between the bulletproof plate 22 and the outer door panel 12 can be ensured while maintaining the appearance of the door, thereby ensuring the safety of the door assembly and the vehicle.

[0052] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0053] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0054] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
