DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort also belong to the protection scope of the present application.

[0035] As shown in Figures 1 to 5 In order to achieve the above-mentioned purpose, according to the first aspect of the present application, an extension piece 20 is provided, comprising a first matching part, the first matching part is used to match with the anti-collision beam body 10 to increase the length of the anti-collision beam body 10 at least in the first direction.

[0036] In this way, the length of the crash beam 1 can be increased, which can increase the contact area of the crash beam 1 with external components, increase the energy absorption effect of the crash beam 1, and facilitate the reduction of damage to automobile components. At the same time, the structure is modularized by splicing of parts, which is convenient for later maintenance and reduces the production cost of the device.

[0037] In the present application, the first direction is the vehicle width direction, the second direction is the vehicle length direction, and the third direction is the vehicle height direction. In this way, the applicability and scope of application of the crash beam body 10 can be further improved to meet the use requirements in different environments.

[0038] Optionally, the crash beam body 10 and the extension piece 20 are detachably connected. When any one of the crash beam body 10 or the extension piece 20 fails or is damaged, it can be individually disassembled and replaced without the need for large-scale disassembly of the entire system, thereby greatly simplifying the maintenance process. Since only the damaged part needs to be replaced instead of the entire system, the maintenance cost can be significantly reduced. The detachable connection allows users to replace the extension piece 20 of different sizes, shapes or functions according to actual needs, thereby meeting various application scenarios.

[0039] Optionally, the extension piece 20 is provided with a first mounting groove 21, and one end of the crash beam body 10 is arranged in the first mounting groove 21. In this way, the space of the first mounting groove 21 is reasonably utilized, thereby reducing the occupied space after assembly of the device, and facilitating the miniaturization development of the crash beam 1.

[0040] Optionally, the length of the extension piece 20 is adjustable. In this way, when the length of the extension piece 20 needs to be changed, the mounting position of the connecting piece 30 and the extension piece 20 remains unchanged, and only the extension piece 20 needs to be replaced without the need for replacing the connecting piece 30, thereby improving the replacement efficiency of the components.

[0041] According to a second aspect of the present application, a crash beam body 10 is provided, comprising: a second matching part, the second matching part being used for matching with an extension piece 20 to increase the length of the crash beam body 10 in the first direction. In this way, the crash beam body 10 and the extension piece 20 are matched, thereby improving the assembly efficiency of the two.

[0042] Optionally, the second matching part is arranged to extend along the first direction, and the second matching part is used for plug-in matching with the extension piece 20. In this way, the crash beam body 10 and the extension piece 20 are matched, thereby improving the assembly efficiency of the two.

[0043] According to a third aspect of the present application, a crash beam assembly is provided, comprising: a crash beam body 10 configured to be connected to a vehicle frame 2; and an extension piece 20 arranged at at least one end of the crash beam body 10, the extension piece 20 being configured to cooperate with the crash beam body 10 to increase the length of the crash beam 1 in the width direction of the vehicle frame 2.

[0044] In the crash beam 1 according to the embodiments of the present application, the extension piece 20 is arranged at at least one end of the crash beam body 10, which can change the length of the crash beam 1, and the change is realized by the splicing of parts, so as to realize the modularization of the structure, thereby facilitating the later maintenance and reducing the production cost of the device.

[0045] In the present application, the crash beam 1 can be a front crash beam of a vehicle, or a rear crash beam of a vehicle.

[0046] Optionally, the extension piece 20 is provided with a first matching part, and the crash beam body 10 is provided with a second matching part, the first matching part and the second matching part being matched to increase the length of the crash beam body 10 in the first direction. In this way, the crash beam body 10 and the extension piece 20 are matched, thereby improving the assembly efficiency of the two.

[0047] Optionally, the first matching part is provided as a mounting groove, and the second matching part is provided as a plug-in piece, the plug-in piece being plug-in matched with the mounting groove. In this way, the crash beam body 10 and the extension piece 20 are matched, thereby improving the assembly efficiency of the two.

[0048] Optionally, the crash beam body 10 is provided with a first connecting hole 11, and the extension piece 20 is provided with a second connecting hole 22 corresponding to the first connecting hole 11, the first connecting hole 11 and the second connecting hole 22 being used for a fixing piece to pass through, so as to fix the extension piece 20 and the crash beam body 10. Through the pre-designed connecting holes, the installer can quickly and accurately pass the fixing piece into the corresponding connecting hole, thereby completing the connection of the extension piece 20 and the crash beam body 10. This connection method does not require additional processing or adjustment, greatly simplifying the operation process. Since the design of the connecting hole makes the installation of the fixing piece simple and fast, the installation efficiency can be significantly improved, and the construction period can be shortened.

[0049] At the same time, through the passing and fastening of the fixing piece (such as a bolt), the connection strength between the extension piece 20 and the crash beam body 10 can be ensured, so as to prevent loosening or falling off during use. Stable connection can ensure the overall stability of the entire system, thereby prolonging the service life of the equipment and improving its performance. When the extension piece 20 or the crash beam body 10 needs to be repaired, the fixing piece can be easily disassembled to separate the extension piece 20 and the crash beam body 10, thereby facilitating the repair or replacement. Since the entire system does not need to be disassembled and replaced on a large scale, the maintenance cost can be significantly reduced.

[0050] Optionally, the first connecting hole 11 and the second connecting hole 22 comprise one of a threaded hole, a rivet hole, or a pin hole. This allows for different configurations depending on the use environment, thus providing versatility to the device.

[0051] Optionally, the inner diameter of the second connecting hole 22 is between 8mm-10mm. A connecting hole with an inner diameter of 8mm-10mm can accommodate a variety of standard-sized fasteners such as bolts, screws, etc., providing users with more options and flexibility. Such a size of connecting hole is suitable for a variety of equipment and machinery, whether small precision instruments or large heavy equipment, there will be appropriate connecting pieces 30 to fix. A connecting hole with an inner diameter of 8mm-10mm can provide sufficient fastening force to ensure the stability and reliability between the connecting parts. A connecting hole that is too large may result in insufficient fastening force, while a connecting hole that is too small may damage the connecting parts due to excessive fastening. The inner diameter range of 8mm-10mm just avoids these problems. A connecting hole of this size is relatively easy to process, without the need for complex processes and equipment, thus reducing manufacturing costs. Since the processing process is relatively simple, production efficiency can be greatly improved, and delivery cycle can be shortened.

[0052] At the same time, the connecting hole with moderate inner diameter is convenient for inspection and maintenance, and users can judge the wear and looseness of the connecting parts by observing the state of the connecting hole. When the connecting parts are damaged or need to be replaced, the connecting hole with an inner diameter of 8mm-10mm makes the replacement process simpler and faster.

[0053] In this application, the inner diameter of the second connecting hole 22 can be set to 8mm, 9mm, or 10mm, etc.

[0054] Optionally, the both ends of the anti-collision beam body 10 are provided with extension pieces 20. The extension pieces 20 at both ends of the body can be regarded as a supplement and strengthening to the original body structure. By increasing the extension pieces 20, the overall length of the body is extended, thereby improving its structural strength and stability. This design makes the body better absorb and disperse the impact force when it is subjected to impact, reducing the damage to other parts of the vehicle. The extension pieces 20 at both ends of the body can also provide additional protection space. In the event of a vehicle collision, especially low-speed collision, the extension pieces 20 can absorb more collision energy, reducing the impact on the vehicle body. In addition, the extension pieces 20 can also prevent the vehicle from losing control to a certain extent, improving the safety of the vehicle.

[0055] Further, the design of the extension pieces 20 at both ends of the body can also adapt to different collision scenarios. For example, in a frontal collision, the extension pieces 20 can interact with the front crash structure to jointly absorb the impact force; in a side collision, the extension pieces 20 can provide additional side protection, reducing damage to the side of the vehicle body. This design enables the body to play a better protective role in different types of collisions. The extension pieces 20 at both ends of the body are usually fixed to the body by bolts or other connection methods. This design is convenient for maintenance and replacement. When the body or extension pieces 20 are damaged, they can be easily removed for replacement or repair, reducing maintenance costs and time.

[0056] Further, as technology advances or needs change, users can easily disassemble old components and install new upgrades or modifications to maintain the system's advanced nature and applicability. By regularly disassembling and inspecting, potential problems can be discovered and repaired in a timely manner, extending the service life of the crash beam body 10 and the extension pieces 20. When a component is damaged, only that component needs to be replaced, rather than the entire system, reducing waste of resources. The detachable connection allows the crash beam body 10 and the extension pieces 20 to be stored separately, saving storage space. During transportation, the crash beam body 10 and the extension pieces 20 can be packaged and transported separately, reducing transportation costs and risks.

[0057] Optionally, the total length of the extension pieces 20 in the width direction of the vehicle frame 2 is between 200mm and 260mm. The appropriate extension of the extension pieces 20 can increase the effective coverage area of the crash beam 1, thereby providing more comprehensive protection to the vehicle frame 2 when the vehicle is in a collision, reducing the extent of damage to the vehicle frame 2. By absorbing and dispersing collision energy, the risk of the vehicle frame 2 being broken or permanently deformed due to a collision is reduced. In the event of a collision between a vehicle and a pedestrian, the design of the crash beam 1 and its extension pieces 20 can reduce the impact force of the vehicle on the pedestrian, reducing the risk of injury to the pedestrian.

[0058] In this application, the extension length of the extension pieces 20 in the width direction of the vehicle frame 2 can be set to 200mm, 250mm, or 260mm, etc.

[0059] Optionally, the total length of the extension pieces 20 in the length direction of the vehicle frame 2 is between 120mm and 180mm.

[0060] The appropriate extension of the extension pieces 20 in the length direction of the vehicle frame 2 can increase the overall length of the crash beam 1, thereby expanding its energy absorption area when the vehicle is in a collision. This helps to more effectively absorb and disperse collision energy, reducing the impact on the vehicle frame 2 and passengers. By lengthening the crash beam 1, it can cover more areas of the vehicle body, thereby providing more comprehensive protection when the vehicle is in a side or rear collision.

[0061] Meanwhile, the extension of the crash beam 1 extension piece 20 can increase the overall rigidity of the vehicle frame 2, making the vehicle more stable during driving. This helps improve the handling of the vehicle, especially at high speeds and during turns. In the event of a collision, the crash beam 1 and its extension piece 20 can jointly absorb the collision energy, reducing the degree of deformation of the vehicle body. This helps maintain the vehicle's driving trajectory and stability, reducing the risk of accidents.

[0062] In this application, the extension length of the extension piece 20 in the length direction of the vehicle frame 2 can be set to 120mm, 150mm or 180mm, etc.

[0063] Optionally, the crash beam 1 also includes a connecting piece 30, one end of which is connected to the extension piece 20, and the other end is connected to the sub-frame. In this way, the two ends of the crash beam 1 are connected to the vehicle frame 2 through the connecting piece 30, optimizing the force transmission path. Not only can the kinetic energy be absorbed by the energy-absorbing structure 40, but also a part of the kinetic energy can be transmitted to the vehicle frame 2, which can improve the vehicle's crash score without increasing the length of the energy-absorbing structure 40.

[0064] Optionally, the connecting piece 30 is detachably connected to the extension piece 20. When the extension piece 20 or the connecting piece 30 is damaged, it can be replaced individually without the need to replace the entire crash beam 1 system. This reduces maintenance costs and allows vehicle owners to upgrade their vehicles according to their needs. Detachable connection allows the extension piece 20 and the connecting piece 30 to be flexibly configured according to different vehicle models and purposes. This helps automobile manufacturers provide standardized crash beam 1 solutions for multiple vehicle models while meeting the individual needs of vehicle owners.

[0065] At the same time, the detachable connection is usually designed to be relatively simple, making it easy for vehicle owners or maintenance personnel to quickly install and remove the extension piece 20. This reduces installation time and improves work efficiency. Detachable connection allows vehicle owners or maintenance personnel to easily inspect the various components of the crash beam 1 system, allowing them to identify and repair potential problems in a timely manner. Through detachable connection, the extension piece 20 and the connecting piece 30 can be replaced when necessary, avoiding wear and fatigue caused by long-term use. This helps extend the service life of the crash beam 1 system. The detachable connecting piece 30 is usually designed with fastening devices such as bolts, nuts, etc. to ensure firm connection.

[0066] Further, this helps maintain the overall stability of the crash beam 1 system during a collision, improving the safety of the vehicle. The detachable crash beam 1 system can be split into smaller parts during transportation and storage, saving space. This is very beneficial to automobile manufacturers, dealers and vehicle owners. Since it can be split into smaller parts for transportation, transportation costs can be reduced. This is particularly important for cross-border or long-distance transportation.

[0067] Further, the end of the extension piece 20 away from the bumper beam body 10 is detachably connected with the subframe, so that the stability of the extension piece 20 when connected with the vehicle as a whole can be further improved, thereby facilitating the improvement of the strength of the bumper beam 1 as a whole.

[0068] Optionally, the extension piece 20 is provided with a second mounting groove 23, and one end of the connecting piece 30 is arranged in the second mounting groove 23. The second mounting groove 23 provides a precise positioning point for the connecting piece 30, ensuring that the connecting piece 30 can be accurately installed at the predetermined position. This helps to reduce errors during installation and improve the stability of the connection. One end of the connecting piece 30 is arranged in the second mounting groove 23 and is fixed by a suitable fastening method (such as a bolt, a nut, etc.), which can effectively prevent the connecting piece 30 from loosening during use. This design helps to ensure the stability and reliability of the bumper beam 1 system. The design of the second mounting groove 23 makes the installation of the connecting piece 30 more simple and fast. It only needs to insert one end of the connecting piece 30 into the second mounting groove 23 and fix it by the fastening method. This reduces the time and labor required for installation.

[0069] Similarly, when the connecting piece 30 needs to be detached, it can be easily taken out of the second mounting groove 23 by loosening the fastening method. This design makes it more convenient to maintain and replace the connecting piece 30. The connecting piece 30 is tightly connected with the extension piece 20 through the second mounting groove 23, which helps to enhance the overall rigidity of the bumper beam 1 system. In the event of a collision, this design can better absorb and disperse impact forces, protecting the safety of the vehicle and passengers. The design of the second mounting groove 23 can also reduce the deformation of the connecting piece 30 and the extension piece 20 during the collision.

[0070] Since the connecting piece 30 is firmly fixed in the second mounting groove 23, it can maintain a relatively stable state during a collision, reducing the risk of deformation and damage. The design of the second mounting groove 23 allows the connecting piece 30 to be adjusted and optimized as needed. For example, by changing the position or angle of the connecting piece 30 in the second mounting groove 23, the layout and performance of the bumper beam 1 system can be adjusted. As technology develops and vehicle performance improves, it may be necessary to upgrade the bumper beam 1 system. The design of the second mounting groove 23 allows the connecting piece 30 to be easily replaced with more advanced or efficient components to meet new requirements.

[0071] Optionally, the second mounting groove 23 is arranged at the end of the extension piece 20 close to the bumper beam body 10. This facilitates the connection of the extension piece 20 with the bumper beam body 10.

[0072] Optionally, the anti-collision beam 1 further comprises an energy-absorbing structure 40 arranged between the anti-collision beam body 10 and the vehicle frame 2, which is used to absorb part of the collision energy of the anti-collision beam 1. The energy-absorbing structure 40 can effectively absorb and disperse the impact force borne by the anti-collision beam 1 when the vehicle collides. This helps to reduce the impact on the vehicle frame 2 and passengers, thereby reducing the risk of injury. By absorbing collision energy, the energy-absorbing structure 40 can reduce damage to the vehicle frame 2 and other critical components such as the engine and transmission. This helps to maintain the vehicle's driving ability and safety. The design of the energy-absorbing structure 40 can slow down the impact speed during a collision, allowing the vehicle to stop more smoothly. This helps to reduce the inertial force generated by sudden stops and protects passengers from secondary injuries.

[0073] At the same time, during the collision process, the energy-absorbing structure 40 can maintain the stability of the vehicle, preventing dangerous situations such as rolling or skidding due to the collision. Since the energy-absorbing structure 40 can absorb part of the collision energy, it can reduce the extent of damage to the vehicle frame 2 and other components. This helps to reduce vehicle repair costs and extend the service life. If the vehicle frame 2 and other critical components remain intact after a collision, the vehicle's residual value will be higher. The design of the energy-absorbing structure 40 helps to improve the vehicle's value retention rate after a collision.

[0074] Further, in a frontal collision, the energy-absorbing structure 40 can absorb the impact force borne by the anti-collision beam 1, reducing the damage to the vehicle frame 2 and passengers. For side collisions, the energy-absorbing structure 40 can also play a role by absorbing and dispersing energy, protecting the vehicle frame 2 and passengers from serious injury. The combination of the anti-collision beam 1 and the energy-absorbing structure 40 forms a comprehensive protection system for the vehicle. This design can improve the safety of the vehicle in various collision situations and provide more comprehensive protection for passengers.

[0075] According to a second aspect of the present application, an anti-collision beam assembly is provided, comprising the above anti-collision beam 1.

[0076] According to a third aspect of the present application, a vehicle is also provided, comprising the above anti-collision beam assembly.

[0077] In the anti-collision beam 1 of the embodiments of the present application, by arranging the extension piece 20 on at least one end of the anti-collision beam body 10, the length of the anti-collision beam 1 can be changed by splicing the parts, achieving modularization of the structure, thereby facilitating later maintenance and reducing the production cost of the device.
