Description

Technical Field

[0001] The present invention belongs to the field of automobiles, and more particularly, relates to an automobile anti-dismantling structure and an assembly method thereof. Background Art

[0002] With the development of society and advancements in technology, automobiles have become an indispensable means of transportation in our daily lives. Door safety is particularly important during vehicle use, especially for specialized vehicles such as police riot vehicles, cash transporters, and ambulances, which place higher demands on door anti-tampering performance. Hinges are key components connecting the vehicle body and doors, and the reliability of their mounting structure directly impacts door safety and the vehicle's overall protective performance.

[0003] Currently, common automotive hinges are typically bolted to the outside of the vehicle body. This structure is common in traditional automotive design and offers a certain degree of stability and cost-effectiveness. However, this conventional mounting structure presents significant security vulnerabilities in certain scenarios and situations. Although some vehicles incorporate fenders and other components to conceal the hinges during subsequent assembly, this concealment method is not very secure. Car fenders are typically made of thin steel or engineering plastics, which have relatively low strength and damage resistance, making them vulnerable to brute force. Once the fender is damaged, the hinge mounting bolts are exposed. These bolts can be easily removed using standard tools such as wrenches and screwdrivers, allowing the door to be opened. This tamper-resistant design clearly fails to meet the requirements of GA 668, "General Technical Requirements for Police Riot Control Vehicles," which stipulate that hinges must not be disassembled or damaged within 10 minutes using mechanical hand tools and an 8-pound hammer.

[0004] In practice, the easy disassembly of these hinges poses numerous safety risks. For ordinary passenger cars, owners may face potential theft of valuables and illegal intrusion. For specialized vehicles, such as the aforementioned police riot vans and armored vehicles, the consequences of easily opening the doors are even more serious, potentially threatening the lives of those inside and the safety of the valuables being transported.

[0005] Although there are some existing improvements to prevent vehicle doors from being easily opened, these measures often have limitations. Some vehicles use special locks or encryption devices to prevent doors from being easily opened, but these locks usually only reinforce the door handles or internal latches, and are not very effective in protecting the key hinges. Some vehicles also attempt to improve safety by increasing the thickness of the doors or using high-strength materials. However, these methods not only increase the weight of the vehicle, leading to increased fuel consumption, but also affect the design aesthetics and practicality of the vehicle to a certain extent. They also significantly increase the manufacturing cost of the vehicle, making it difficult to promote and apply them on a large scale.

[0006] In summary, the anti-dismantling performance of automobile hinges in the existing technology has obvious deficiencies and cannot meet the growing demand for vehicle safety. In particular, its protection capability is extremely weak when facing violent disassembly tools. Summary of the Invention

[0007] To address the above-mentioned deficiencies or improvements in the prior art, the present invention provides an automotive anti-tampering structure and assembly method thereof. Based on the position of the hinge relative to the door and body when the door is open or closed, an anti-tampering cover is provided on the hinge. The anti-tampering cover can be assembled when the door is open. However, when the door is closed, the anti-tampering cover cannot be removed using a bolt removal tool due to the positional limitations and obstruction of the door's end face near the front of the vehicle. The anti-tampering cover also protects the bolts, making them impossible to remove from outside the vehicle using tools, thereby achieving the purpose of anti-tampering. This anti-tampering structure does not modify the existing door and hinge assembly structure and has the advantages of being simple and reliable.

[0008] To achieve the above objectives, according to one aspect of the present invention, there is provided an automobile anti-tampering structure, characterized in that it comprises a vehicle body, a door, a hinge, and an anti-tampering cover plate, wherein the vehicle body and the door are hingedly connected together by the hinge, and when the door is closed, a concave angle is formed between the end surface of the door near the front of the vehicle and the outer side surface of the vehicle body, and when the door is open, a gap is formed between the end surface of the door near the front of the vehicle and the vehicle body, wherein:

[0009] The hinge includes a movable page plate and a fixed page plate hinged together by a hinge shaft, the movable page plate being fixed to the end surface of the vehicle door close to the front of the vehicle by a plurality of first bolts, the bolt head of each first bolt being exposed at the end surface of the vehicle door close to the front of the vehicle, the fixed page plate being fixed to the outer side surface of the vehicle body by a plurality of second bolts, the fixed page plate being provided with a plurality of first connecting holes, each of the first connecting holes being arranged corresponding to a gap when the vehicle door is opened, so as to allow a third bolt to be installed on the first connecting hole;

[0010] The anti-tamper cover is provided with a second connection hole at a position corresponding to each first connection hole;

[0011] When the vehicle door is opened, the third bolt passes through the first connecting hole and the second connecting hole through the gap to fix the anti-tamper cover plate to the fixed page plate, and the anti-tamper cover plate and the fixed page plate are connected by a plurality of third bolts, the bolt heads of the third bolts are close to the end face of the vehicle door close to the front of the vehicle, and the bolt tail ends of the third bolts are away from the end face of the vehicle door close to the front of the vehicle. When the vehicle door is closed, the distance between the end face of the vehicle door close to the front of the vehicle and the bolt head of the third bolt is within a set threshold, so as to limit the displacement of the bolt head of the third bolt, so that the third bolt cannot be removed from the fixed page plate and the anti-tamper cover plate when the vehicle door is closed;

[0012] The anti-disassembly cover plate cooperates with the fixed page plate to shield the bolt heads of all second bolts to prevent an external bolt removal tool from twisting the bolt heads of the second bolts to remove the second bolts.

[0013] Preferably, the anti-tamper cover covers all the bolt heads of the first bolts when the vehicle door is closed and the distance between the anti-tamper cover and the bolt heads of the first bolts is within a set threshold to limit the displacement of the bolt heads of the first bolts, so that the first bolts cannot be removed from the end face of the vehicle door close to the front of the vehicle when the vehicle door is closed.

[0014] Preferably, the fixed page plate is L-shaped as a whole and includes a first part and a second part that are perpendicular to each other, the first part of the fixed page plate is provided with a plurality of first through holes, the second part of the fixed page plate is provided with a notch, a part of the movable page plate extends into the notch and is hinged to the second part of the fixed page plate, and the second part is provided with a plurality of first connecting holes.

[0015] Preferably, the fixed page plate has a plurality of first ridges and these first ridges surround the bolt head of the second bolt, and each of the first ridges abuts against the anti-disassembly cover plate to prevent an external bolt removal tool from twisting the bolt head of the second bolt to remove the second bolt from the fixed page plate.

[0016] Preferably, the fixed page plate has a plurality of second ridges and these second ridges surround the bolt heads of the second bolts, and each of the second ridges abuts against the fixed page plate to prevent an external bolt removal tool from twisting the bolt heads of the second bolts and removing the second bolts from the fixed page plate.

[0017] Preferably, the anti-dismantling cover is provided with holes at positions corresponding to the bolt heads of each second bolt, and the bolt heads of each second bolt extend into one of the holes and do not extend beyond the side of the anti-dismantling cover away from the vehicle body, and the hole walls are in contact with the bolt heads of the second bolts to prevent external bolt removal tools from twisting the bolt heads of the second bolts to remove the second bolts from the fixed page plate.

[0018] Preferably, the distance between the bolt head of the third bolt and the vehicle body and the distance between the bolt head and the first bolt are both within set thresholds, and these distances prevent an external bolt removal tool from twisting the bolt head of the third bolt after contacting the bolt head of the third bolt.

[0019] Preferably, the tamper-evident cover is made of stainless steel, aluminum alloy or carbon steel, and has a thickness greater than 2.5 mm.

[0020] Preferably, both ends of the hinge shaft are upset respectively to limit the axial displacement of the hinge shaft.

[0021] According to another aspect of the present invention, there is also provided a method for assembling an automobile anti-dismantling structure, characterized in that it comprises the following steps:

[0022] 1) The movable plate and the fixed plate of the hinge are hinged together through a hinge shaft. The movable plate of the hinge is fixed to the end surface of the door near the front of the vehicle by a first bolt, and the fixed plate of the hinge is fixed to the outer side surface of the vehicle body by a second bolt;

[0023] 2) aligning each second connection hole on the tamper-evident cover plate with a first connection hole on the fixed page plate. After the second connection holes are aligned with the first connection holes, the tamper-evident cover plate cooperates with the fixed page plate to shield the bolt heads of all second bolts, thereby preventing an external bolt removal tool from twisting the bolt heads of the second bolts and removing the second bolts from the fixed page plate.

[0024] 3) The vehicle door is opened to form a gap between the end surface of the vehicle door near the front of the vehicle and the vehicle body, and a third bolt is passed through the first connecting hole and the second connecting hole in the gap, with the bolt head of the third bolt close to the end surface of the vehicle door near the front of the vehicle and the bolt tail of the third bolt away from the end surface of the vehicle door near the front of the vehicle;

[0025] 4) Tighten the third bolt at the gap using a socket wrench so that the third bolt fixes the fixed page plate and the anti-tamper cover together, and ensure that the distance between the end face of the door close to the front of the vehicle and the bolt head of the third bolt is within a set threshold when the door is closed, so as to limit the displacement of the bolt head of the third bolt, so that the third bolt cannot be removed from the fixed page plate and the anti-tamper cover when the door is closed.

[0026] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0027] 1) The present invention provides an anti-dismantling structure for automobiles, which provides an anti-dismantling cover on the hinge to protect the hinge from disassembly. This ensures that the doors of special vehicles remain intact within a specified time when violently disassembled by mechanical or manual tools, thus meeting the requirements of relevant technical regulations.

[0028] 2) An automobile anti-dismantling structure of the present invention provides a plurality of first connecting holes corresponding to the gaps when the vehicle door is opened on the fixed page plate, and cooperates with the second connecting holes on the anti-dismantling cover plate, and uses a third bolt for connection and fixation, so that when the vehicle door is closed, the bolt head of the third bolt is close to the end face of the vehicle door close to the front of the vehicle and the spacing is within a set threshold, which limits the displacement of the third bolt and the third bolt cannot be removed from the fixed page plate and the anti-dismantling cover plate. At the same time, the anti-dismantling cover plate cooperates with the fixed page plate to block all the second bolts, preventing external bolt removal tools from twisting the bolt heads of the second bolts, thereby effectively preventing criminals from removing the anti-dismantling cover plate from the outside and then removing the second bolts and the vehicle door, which can effectively prevent external disassembly and improve the safety protection performance of the vehicle.

[0029] 3) The automobile anti-dismantling structure of the present invention does not change the basic assembly structure of the original door and hinge, but cleverly adds an anti-dismantling cover and a corresponding bolt connection design on the existing basis. While achieving the anti-dismantling function, it ensures the simplicity and reliability of the structure, making it easy to promote and apply on various types of automobiles without requiring large-scale adjustments to the vehicle's manufacturing process and production process.

[0030] 4) The automobile anti-dismantling structure of the present invention enables the vehicle door to form a relatively closed protection system that is difficult to be destroyed from the outside when closed, providing more reliable protection for the vehicle when parked or driving, enhancing the vehicle's anti-theft and anti-destruction capabilities, helping to reduce the risk of illegal intrusion and theft of the vehicle, and is of great significance for improving the overall safety performance of the vehicle.

[0039] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0040] Reference Figures 1 to 6 A vehicle anti-tampering structure includes a vehicle body 2, a door 3, a hinge 1, and an anti-tampering cover 4. The vehicle body 2 and the door 3 are hinged together by the hinge 1. When the door 3 is closed, a recessed angle is formed between the end surface 31 of the door 3 near the front of the vehicle and the outer side surface of the vehicle body 2. When the door 3 is open, a gap 9 is formed between the end surface 31 of the door 3 near the front of the vehicle, which is also the front face of the door 3, and the vehicle body 2. The end face opposite to the end surface 31 of the door 3 near the front of the vehicle is the end surface 32 of the door 3 near the rear of the vehicle, and a door lock is installed on the end surface 32 of the door 3 near the rear of the vehicle.

[0041] The hinge 1 includes a movable page plate 11 and a fixed page plate 12 hinged together by a hinge shaft 13. The movable page plate 11 is fixed to the end face 31 of the door 3 close to the front of the vehicle by a plurality of first bolts 5. Therefore, the movable page plate 11 is in contact with the end face 31 of the door 3 close to the front of the vehicle. The bolt head of each first bolt 5 is exposed at the end face 31 of the door 3 close to the front of the vehicle. Therefore, when the door 3 is closed, the center line of each first bolt 5 extends along the front and rear direction of the vehicle; the fixed page plate 12 is fixed to the outer side face of the vehicle body 2 by a plurality of second bolts 6. Therefore, the fixed page plate 12 is in contact with the outer side face of the vehicle body 2. A plurality of first connecting holes 121 are provided on the fixed page plate 12. Each of the first connecting holes 121 is arranged corresponding to the gap 9 when the door 3 is opened, so that the third bolt 7 can be installed on the first connecting hole 121.

[0042] The tamper-evident cover plate 4 is provided with a second connection hole 41 at a position corresponding to each first connection hole 121 .

[0043] When the vehicle door 3 is opened, the third bolt 7 passes through the first connecting hole 121 and the second connecting hole 41 from the gap 9 to fix the anti-disassembly cover plate 4 to the fixed page plate 12, and the anti-disassembly cover plate 4 and the fixed page plate 12 are connected by multiple third bolts 7, the bolt head of the third bolt 7 is close to the end face 31 of the vehicle door 3 close to the front of the vehicle, and the bolt tail end of the third bolt 7 is away from the end face 31 of the vehicle door 3 close to the front of the vehicle. When the vehicle door 3 is closed, the distance between the end face 31 of the vehicle door 3 close to the front of the vehicle and the bolt head of the third bolt 7 is within a set threshold to limit the displacement of the bolt head of the third bolt 7, so that the third bolt 7 cannot be removed from the fixed page plate 12 and the anti-disassembly cover plate 4 when the vehicle door 3 is closed.

[0044] The anti-disassembly cover 4 cooperates with the fixed page plate 12 to block the bolt heads of all second bolts 6 to prevent external bolt removal tools such as wrenches and socket wrenches from twisting the bolt heads of the second bolts 6 to remove the second bolts 6.

[0045] The second bolt 6 is a key component that fixes the hinge 1 and the door 3 to the vehicle body 2. Once the second bolt 6 is removed, the hinge 1 and the door 3 can be removed from the vehicle body 2 together (the first bolt 5 is also very important, but even if the first bolt 5 is removed, due to the contact and restriction of the end face 31 of the door 3 close to the front of the vehicle on the movable panel 11, the movable panel 11 will always be in contact with the end face of the door 3 close to the front of the vehicle. The movable panel 11 cannot be rotated to avoid the door 3, and the door 3 cannot be translated and rotated to be unlocked. Therefore, the hinge 1 and the door 3 cannot be removed from the vehicle body 2 together). After the anti-dismantling cover plate 4 is assembled, the second bolt 6 on the fixed panel 12 can be blocked, and the second bolt 6 cannot be removed using a bolt removal tool. At the same time, when the door 3 is closed, the anti-dismantling cover plate 4 and the third bolt 7 cannot be removed from the outside of the vehicle, thereby achieving the purpose of anti-dismantling. The tamper-evident cover 4 can be designed to completely or partially obstruct the bolt head, as long as it blocks the removal of the second bolt 6 by a bolt removal tool. This ensures that when the door 3 is closed, the hinge 1 cannot be removed normally from outside the vehicle, and thus the door 3 cannot be removed by this method, thus achieving the anti-tampering purpose. Therefore, the third bolt 7 of the present invention can only be installed and removed through the gap 9 when the door 3 is open. When the door 3 is closed, the gap 9 that facilitates the tightening of the third bolt 7 does not exist, making the third bolt 7 impossible to install or remove.

[0046] Furthermore, the anti-dismantling cover plate 4 blocks all the bolt heads of the first bolts 5 when the vehicle door 3 is closed and the distance between the anti-dismantling cover plate 4 and the bolt heads of the first bolts 5 is within a set threshold, so as to limit the displacement of the bolt heads of the first bolts 5, so that the first bolts 5 cannot be removed from the end face 31 of the vehicle door 3 close to the front of the vehicle when the vehicle door 3 is closed.

[0047] The first bolt 5 is a key component that secures the movable leaf plate 11 to the vehicle door 3. Once removed, the normal opening and closing of the vehicle door 3 and the stability of the hinge 1 will be affected. By having the anti-tamper cover 4 shield the bolt head of the first bolt 5 when the vehicle door 3 is closed, and controlling the spacing within a set threshold, the displacement of the first bolt 5 is limited. Even if criminals remove the anti-tamper cover 4, it is difficult to directly access the bolt head of the first bolt 5 and remove it. This further improves the reliability and safety of the entire anti-tamper structure, ensures that the vehicle door 3 cannot be easily opened when closed, and effectively prevents illegal intrusion into the vehicle.

[0048] By adding the anti-dismantling cover plate 4 as a protection measure for the first bolt 5, the anti-dismantling structure forms an all-round protection for the first bolt 5, the second bolt 6 and the third bolt 7. The various protection parts cooperate and complement each other to build a more complete and solid anti-dismantling system, thereby improving the anti-destruction ability of the entire hinge 1 system and providing more comprehensive safety protection for the vehicle.

[0049] By designing the spacing requirements between the anti-dismantling cover 4 and the bolt head of the first bolt 5, it is possible to better adapt to bolts of different sizes and specifications, ensuring that in actual applications, the anti-dismantling cover 4 can fully play its shielding and limiting role on the first bolt 5, avoiding the disassembly tool from being able to reach and contact the bolt head due to a gap that is too large, or avoiding the normal closing and use of the vehicle door 3 due to a gap that is too small, thereby optimizing the overall protection effect and improving the practicality and reliability of the anti-dismantling structure.

[0050] Furthermore, the fixed page plate 12 is L-shaped as a whole and includes a first part 1201 and a second part 1202 that are perpendicular to each other. The first part 1201 of the fixed page plate 12 is provided with a plurality of first through holes, and the second part 1202 of the fixed page plate 12 is provided with a notch. A part of the movable page plate 11 extends into the notch and is hinged to the second part 1202 of the fixed page plate 12. The second part 1202 is provided with a plurality of first connecting holes 121.

[0051] The L-shaped fixed page plate 12 structure enables it to better fit and connect with the outer side surface of the vehicle body 2 and the end surface 31 of the door 3 close to the front of the vehicle. The first part 1201 is provided with a first through hole, and the second bolt 6 passes through the first through hole to connect the first part 1201 to the vehicle body 2. The second part 1202 is hinged to the movable page plate 11 through the hinge shaft 13, and a notch is provided to allow a part of the movable page plate 11 to extend into it. This design increases the connection area and strength between the hinge 1 and the vehicle body 2 and the door 3, improves the stability of the hinge 1 during vehicle driving, ensures smooth opening and closing of the door 3, reduces the risk of loosening or damage of the hinge 1 due to bumps or external force impact, thereby extending the service life of the hinge 1 and improving the overall reliability and safety of the vehicle.

[0052] Multiple first connection holes 121 are provided in the second portion 1202 of the fixed leaf plate 12, allowing the tamper-evident cover 4 to be accurately connected to corresponding positions on the fixed leaf plate 12, facilitating assembly and installation when the vehicle door 3 is open. This also ensures the stability of the tamper-evident cover 4 after installation, allowing it to better shield and protect the bolts. Furthermore, the L-shaped structure of the fixed leaf plate 12 provides a reasonable spatial layout for the installation and articulation of the movable leaf plate 11, enabling the entire hinge 1 system to operate in a coordinated manner during the opening and closing of the vehicle door 3, creating favorable conditions for the effective implementation of the tamper-evident structure.

[0053] The L-shaped design of the fixed leaf plate 12 and the hinged connection between the movable leaf plate 11 and the fixed leaf plate 12 form an organic whole. The interconnected and mutually supportive components of the hinge 1 enhance the structural rigidity and deformation resistance of the entire hinge 1 system. This holistic structure effectively disperses stress and reduces the possibility of localized damage in the event of external impact or damage from removal tools, thereby enhancing the integrity and stability of the anti-tampering structure and further improving the protective performance of the vehicle door 3.

[0054] Furthermore, the anti-tamper cover 4 is made of stainless steel, aluminum alloy or carbon steel, and has a thickness greater than 2.5 mm.

[0055] Stainless steel, aluminum alloy, and carbon steel are all high-strength metal materials that can effectively resist external impact and damage, preventing criminals from violently destroying the anti-tamper cover plate 4 and accessing the mounting bolts of the hinge 1. A design with a thickness greater than 2.5mm further enhances the cover's resistance to damage, making it difficult to pry, bend, or penetrate, thereby better protecting key components such as internal bolts, ensuring the anti-tamper function of the door 3 is not affected and enhancing its protective performance. These metal materials possess excellent rigidity and can provide stable support and protection for the hinge 1 during vehicle operation and when subjected to various external forces. They maintain a tight connection between the hinge 1 and the vehicle body 2 and door 3, ensuring smooth and stable opening and closing of the door 3, and preventing loosening or failure of the hinge 1 due to deformation or damage to the anti-tamper cover plate 4. This improves the reliability of the entire door 3 system and ensures structural stability.

[0056] The vehicle door 3 experiences a variety of complex mechanical stresses during opening and closing, as well as during vehicle operation, including tensile, compressive, shear, and bending stresses. Using the aforementioned metal material and ensuring a certain thickness allows the tamper-evident cover plate 4 to withstand these complex stresses, making it less susceptible to fatigue cracking and fracture. This ensures that the tamper-evident cover plate 4 can function properly throughout the vehicle's service life and adapt to complex stresses.

[0057] High-quality materials and sufficient thickness can withstand damage from various natural environmental factors and human factors, reduce the frequency of repairs and replacements due to material aging, corrosion, deformation, etc., reduce usage costs and maintenance workload, ensure that the anti-dismantling structure always maintains good working condition throughout the vehicle's life cycle, and provide long-term and stable safety protection for the vehicle.

[0058] A cover with a thickness greater than 2.5mm can ensure that there will be no obvious deformation or defects during processing and use, thereby improving the overall aesthetics and refinement of the vehicle and enhancing the vehicle's market competitiveness and attractiveness.

[0059] Furthermore, the second portion 1202 has an ear plate 1203 , and the first connection hole 121 is provided on the ear plate 1203 . The ear plate 1203 is convenient for extension and arrangement so that the second connection hole 41 on the tamper-evident cover plate 4 can be well aligned.

[0060] Furthermore, the fixed page plate 12 has a plurality of first ridges 42 and these first ridges 42 surround the bolt head of the second bolt 6. Each of the first ridges 42 abuts against the anti-disassembly cover plate 4 to prevent an external bolt removal tool from twisting the bolt head of the second bolt 6 to remove the second bolt 6 from the fixed page plate 12.

[0061] The first ridge 42 forms a physical barrier between the fixed leaf plate 12 and the tamper-evident cover 4, tightly enclosing the bolt head of the second bolt 6 and making it more difficult for unauthorized access tools to reach and remove the bolt head. Even if the tamper-evident cover 4 is damaged or deformed, the first ridge 42 continues to block access by tamper-evident tools, providing dual protection for the second bolt 6 and effectively enhancing the overall security and safety of the tamper-evident structure. This better meets the stringent tamper-evident requirements of special vehicles for the door 3 and enhances tamper-evident protection.

[0062] The design of multiple first ridges 42 not only provides protection but also increases the structural rigidity and strength of the fixed leaf plate 12, ensuring greater stability and deformation resistance when subjected to external impact, vibration, or removal forces. This further enhances the reliability of the entire hinge 1 system and anti-tear structure, reducing the risk of bolt loosening or anti-tear function failure due to deformation of the fixed leaf plate 12. This ensures the vehicle can operate normally under various complex operating conditions, protecting the safety of occupants and property, and enhancing structural rigidity.

[0063] The design of the first ridge 42 abutting the tamper-evident cover 4 makes the fixed leaf plate 12 and the tamper-evident cover 4 fit more tightly and harmoniously, forming an integrated protective structure. This integrated protection method not only improves the protection effect, but also makes the entire tamper-evident structure more compact, optimizing the integration of the protective structure.

[0064] Furthermore, the fixed page plate 12 has a plurality of second ridges 122 and these second ridges 122 surround the bolt head of the second bolt 6. Each second ridge 122 abuts against the fixed page plate 12 respectively to prevent an external bolt removal tool from twisting the bolt head of the second bolt 6 and removing the second bolt 6 from the fixed page plate 12.

[0065] The second ridge 122 is arranged inside the fixed page plate 12 to provide an additional layer of protection for the bolt head of the second bolt 6. By abutting against the fixed page plate 12 itself, a closed protective space is formed, making it difficult for external disassembly tools to find an entry point from the internal structure of the fixed page plate 12 to twist the bolt head. Combined with the protection of the first ridge 42, an internal and external dual protection mechanism is formed, which greatly enhances the protection reliability of the second bolt 6, reduces the risk of the vehicle door 3 being illegally opened due to the removal of the second bolt 6, improves the safety performance of the vehicle, and enhances the protection reliability.

[0066] The second ridge 122, a structural feature of the fixed leaf plate 12, is tightly connected to and abuts against the fixed leaf plate 12, further enhancing the overall structural stability of the fixed leaf plate 12. During vehicle operation, even when subjected to certain external impacts or vibrations, the fixed leaf plate 12 maintains a stable shape and position, ensuring the secure connection of the second bolt 6. This maintains the stable operation of the entire hinge 1 system and ensures the normal opening and closing function of the door 3. This extends the service life of the hinge 1 and door 3, reduces the frequency of repair and replacement, and improves structural stability.

[0067] The design of the second ridge 122 fully considers the impact of the internal structure of the fixed page plate 12 on the bolt protection. Through the reasonable layout and shape design of the second ridge 122, the fixed page plate 12 can provide effective protection for the second bolt 6 in its own structure without the need to add too many complex protective components. It not only ensures the protection effect, but also simplifies the structure and reduces production costs. At the same time, it is also conducive to improving assembly efficiency and maintenance convenience, reflecting the sophistication and practicality of the design and optimizing the protection detail design.

[0068] Furthermore, the anti-tamper cover 4 is provided with holes 43 at positions corresponding to the bolt heads of each second bolt 6. The bolt head of each second bolt 6 extends into one of the holes 43 and does not extend beyond the side of the anti-tamper cover 4 away from the vehicle body 2. The hole wall of the hole 43 contacts the bolt head of the second bolt 6 to prevent an external bolt removal tool from twisting the bolt head of the second bolt 6 and removing the second bolt 6 from the fixed page plate 12.

[0069] By specially providing a hole 43 for the bolt head of each second bolt 6 on the anti-dismantling cover 4 and controlling the size and depth of the hole 43, the bolt head is inserted into the hole 43 and does not exceed the side of the anti-dismantling cover 4 away from the vehicle body 2. At the same time, the hole wall is in close contact with the bolt head. This design can accurately wrap and shield the bolt head of the second bolt 6, so that the disassembly tool cannot contact the bolt head from the outside of the anti-dismantling cover 4, thereby effectively preventing the second bolt 6 from being twisted by external disassembly tools, further improving the reliability and safety of the anti-dismantling structure, ensuring the connection stability of the hinge 1, and accurately protecting the second bolt 6.

[0070] The provision of hole 43 conceals the bolt head of second bolt 6 within tamper-evident cover plate 4, making it more difficult to observe and access from the outside. This increases the difficulty and time required for removal by unauthorized personnel, thus providing a certain degree of concealed protection. Furthermore, the shape and size of hole 43 can be customized according to the specifications of second bolt 6, allowing for better adaptation to different bolt types, improving the flexibility and adaptability of the protection, meeting the requirements of various vehicles, and enhancing the concealment of the protection.

[0071] This design of incorporating the bolt head of the second bolt 6 into the hole 43 of the anti-dismantling cover 4 makes the entire protective structure more compact and integrated, reduces the gaps and redundant parts between components, improves space utilization, and reduces the impact of the anti-dismantling structure on the overall layout of the vehicle. At the same time, it also facilitates the realization of more efficient protection effects in a limited space and optimizes the compactness of the protective structure.

[0072] Furthermore, when the vehicle door 3 is closed, the distance between the bolt head of the third bolt 7 and the vehicle body 2 and the distance between the bolt head and the first bolt 5 are both within the set thresholds. These distances prevent an external bolt removal tool from twisting the bolt head of the third bolt 7 after contacting the bolt head of the third bolt 7.

[0073] By strictly controlling the spacing between the bolt head of the third bolt 7 and the vehicle body 2 and the first bolt 5, even if an unauthorized person can access the bolt head of the third bolt 7 after the vehicle door 3 is closed, the limited space prevents the removal tool from properly applying force to the bolt head. This effectively prevents the third bolt 7 from being removed, further enhancing the effectiveness of the anti-tampering structure, improving the safety and reliability of the vehicle door 3, better protecting the vehicle and the people and items inside, and enhancing the anti-tampering effect. The third bolt 7 can only be installed and removed through the gap between the vehicle door 3 and the vehicle body 2 when the vehicle door 3 is open.

[0074] This spacing requirement is determined based on comprehensive consideration of factors such as the movement trajectory of the door 3 when closed, the structure of the vehicle body 2, and the relative positions of the various components. It can ensure the reasonable layout of the entire anti-dismantling structure on the vehicle, avoid assembly difficulties, interference problems, or reduced protective performance due to improper spacing between components, improve the design rationality and production efficiency of the vehicle, and also provide convenient conditions for subsequent maintenance and inspection, thereby optimizing the rationality of the structural layout.

[0075] This design, which optimizes bolt protection from the perspective of spacing, fully considers various possible situations during actual use and incorporates protective measures into every detail of the entire door 3 when it is closed, making the anti-dismantling structure more complete and thorough, further improving the overall safety performance of the vehicle, reducing the risk of illegal disassembly and intrusion, and improving the overall safety level.

[0076] Furthermore, both ends of the hinge shaft 13 are upset to limit the axial displacement of the hinge shaft 13. The upset hinge shaft 13 increases the difficulty of removal, requiring special tools and considerable force to damage the hinge shaft 13. This prolongs the time it takes for the vehicle door 3 to be illegally disassembled, thereby improving vehicle safety and enhancing the anti-disassembly performance.

[0077] According to another aspect of the present invention, there is also provided a method for assembling an automobile anti-dismantling structure, comprising the following steps:

[0078] 1) The movable leaf plate 11 and the fixed leaf plate 12 of the hinge 1 are hinged together through the hinge shaft 13. The movable leaf plate 11 of the hinge 1 is fixed to the end surface 31 of the door 3 close to the front of the vehicle through the first bolt 5, and the fixed leaf plate 12 of the hinge 1 is fixed to the outer side surface of the vehicle body 2 through the second bolt 6.

[0079] 2) Align each second connection hole 41 on the anti-tamper cover 4 with a first connection hole 121 on the fixed page plate 12. After the second connection holes 41 and the first connection holes 121 are aligned, the anti-tamper cover 4 cooperates with the fixed page plate 12 to cover the bolt heads of all second bolts 6 to prevent external bolt removal tools from twisting the bolt heads of the second bolts 6 and removing the second bolts 6 from the fixed page plate 12.

[0080] 3) The vehicle door 3 is opened so that a gap 9 is formed between the end face 31 of the vehicle door 3 close to the front of the vehicle and the vehicle body 2. The third bolt 7 is passed through the first connecting hole 121 and the second connecting hole 41 at the gap 9, and the bolt head of the third bolt 7 is close to the end face 31 of the vehicle door 3 close to the front of the vehicle and the bolt tail end of the third bolt 7 is away from the end face 31 of the vehicle door 3 close to the front of the vehicle.

[0081] 4) Tighten the third bolt 7 at the gap 9 using the socket wrench 8 so that the third bolt 7 fixes the fixed page plate 12 and the anti-tamper cover plate 4 together, and ensure that the distance between the end face 31 of the door 3 close to the front of the vehicle and the bolt head of the third bolt 7 is within a set threshold when the door 3 is closed, so as to limit the displacement of the bolt head of the third bolt 7, so that the third bolt 7 cannot be removed from the fixed page plate 12 and the anti-tamper cover plate 4 when the door 3 is closed.

[0082] According to the assembly method, the hinge 1 is first installed and secured, followed by the tamper-evident cover plate 4 and the third bolt 7. This rational installation sequence ensures that the tamper-evident cover plate 4 accurately covers and protects the second bolt 6 on the fixed leaf plate 12 when the door 3 is open, and effectively shields the bolt head of the first bolt 5 when the door 3 is subsequently closed, thereby providing comprehensive protection for the bolts on the hinge 1 and preventing unauthorized removal from the outside of the vehicle.

[0083] This assembly method allows the third bolt 7 to pass through the first connecting hole 121 and the second connecting hole 41 through the gap 9 when the door 3 is open, placing the bolt head of the third bolt 7 near the end face 31 of the door 3 near the front of the vehicle, while the bolt tail of the third bolt 7 is positioned away. Controlling this installation direction and position is crucial for achieving the anti-tampering function. It ensures that when the door 3 is closed, the distance between the bolt head of the third bolt 7 and the end face 31 of the door 3 near the front of the vehicle is within a set threshold, limiting the displacement of the bolt head and making it impossible for criminals to remove the third bolt 7 when the door 3 is closed. This ensures the non-detachable connection between the anti-tampering cover plate 4 and the fixed leaf plate 12, effectively protecting the bolts on the hinge 1.

[0084] It will be easily understood by those skilled in the art that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
