It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.
[0035] Combination Figures 1 to 6 As shown, according to a specific embodiment of the present application, a vehicle external auxiliary safety device is provided.
[0036] The vehicle external auxiliary safety device includes: a first rod member 1, at least two first rod members 1, the length direction of the first rod members 1 extends along the first direction, at least two first rod members 1 are arranged at intervals along the second direction, at least part of the first rod members 1 are located on one side of the vehicle body, at least part of the first rod members 1 are located on one side of the fuel tank, and the first rod member 1 is connected to at least one of the vehicle beam and the bottom accessory of the vehicle body; wherein, a first pedaling space 10 for a target object to pedal is formed between two adjacent first rod members 1 along the second direction, and a second pedaling space 20 for a target object to pedal is formed on the top side of the first rod member 1 located at the topmost position along the second direction.
[0037] Preferably, the first direction is the length direction of the vehicle, and the second direction is the height direction of the vehicle.
[0038] Specifically, the vehicle beam includes a cross beam and a longitudinal beam, and the accessories at the bottom of the vehicle compartment include at least one of the following: a fuel tank, a gas tank, a tool box, a battery box, a water tank, a urea tank, and a spare tire box, and the above components are generally arranged at the bottom of the vehicle compartment. The fuel tank is located at the bottom of the vehicle compartment.
[0039] The target object can be a person or a vehicle boarding equipment, where the vehicle boarding equipment includes components such as a load plate, a hydraulic lifting platform, a mobile loading ramp, a maintenance tool box, straps and other cargo fixing devices.
[0040] By applying the technical solution of the present invention, the vehicle external auxiliary safety device has at least two first rods 1, the first rods 1 are located on one side of the vehicle compartment, at least part of the first rods 1 are located on one side of the fuel tank, and at the same time, the first pedaling space 10 and the second pedaling space 20 are formed by at least two first rods 1. On the one hand, the vehicle external auxiliary safety device integrates the vehicle compartment protection, fuel tank protection and pedaling functions at the same time. On the other hand, since the original pedaling ladder can be eliminated, the side protection of a larger area can be achieved while reducing the production cost, shortening the production cycle. The technical solution of the present application effectively solves the problem of high cost of vehicle external auxiliary safety devices in the prior art.
[0041] The first rod 1, as a protective structure on the side of the vehicle, can provide additional protection for the fuel tank and the vehicle compartment when a side collision occurs, thereby reducing potential damage. Especially on commercial vehicles, the side protection structure is crucial to prevent pedestrians, cyclists or other vehicles from being involved in a side collision, thereby protecting the safety of people inside and outside the vehicle.
[0042] In an optional embodiment, if the first rod 1 is made of a lightweight material such as aluminum alloy, its hollow structure can be utilized to significantly reduce weight without sacrificing strength, which has a positive impact on improving the vehicle's fuel economy, reducing emissions, and improving driving performance and cargo capacity.
[0043] By adjusting the spacing between the first rods 1 and the positions of the mounting holes, a modular design can be achieved, so that the safety device can adapt to different vehicle models and chassis layouts, thereby improving assembly efficiency and facilitating maintenance and replacement.
[0044] The first rod 1 not only assumes the responsibility of safety protection, but also integrates the pedaling function, which provides convenience for the driver and passengers to get on and off the vehicle. The design of the first pedaling space 10 and the second pedaling space 20 allows the target object (i.e., person) to pedal at multiple positions, which increases flexibility and also eliminates the need for additional pedaling ladders, further reducing the manufacturing cost and weight of the vehicle.
[0045] Furthermore, this design can ensure that the vehicle meets the requirements of domestic and international side protection regulations, especially in terms of standards related to fuel tank protection and side impact safety, which helps the vehicle pass safety certification.
[0046] Integrated safety guards and kick-off features reduce clutter on the side of the vehicle, improving the exterior design of the vehicle, making it look cleaner and more professional.
[0047] Furthermore, the vehicle external auxiliary safety device also includes: a second rod 3, the length direction of the second rod 3 is extended along the second direction, the second rod 3 is connected to each first rod 1, the second rod 3 is connected to at least one of the vehicle beam and the bottom accessory of the vehicle body, and there is at least one second rod 3, wherein when there are multiple second rods 3, the multiple second rods 3 are spaced apart along the first direction.
[0048] A second rod 3 is added to the vehicle external auxiliary safety device, and its length direction extends along the second direction and connects the first rods 1, and is connected to the vehicle beam or the bottom attachment of the vehicle compartment. This design provides additional stability and structural strength, and the specific benefits are as follows:
[0049] Enhanced structural stability: The second rod 3, as a transverse connecting member, can effectively enhance the stability of the entire side protection structure. By vertically connecting with the first rod 1, a "tic-tac-toe" or "grid" structure is formed, which increases the lateral rigidity of the structure, so that it can better absorb and disperse the impact force in a side collision, protecting the safety of the vehicle and its occupants.
[0050] Improved assembly strength: The direct connection between the second rod 3 and the vehicle beam or the bottom attachment of the vehicle compartment can improve the connection strength between the entire safety device and the vehicle body, ensuring that in extreme cases, the side protection structure will not fall off the vehicle, providing continuous protection.
[0051] Supplement of modular design: When there are multiple second rods 3 and they are spaced apart along the first direction (i.e., the vehicle length direction), this design further strengthens the modular concept. The number and position of the second rods 3 can be flexibly adjusted according to the width and layout requirements of different vehicle models, so that the entire safety device can better adapt to various chassis designs.
[0052] Lightweight and cost control: Similar to the first rod 1, the second rod 3 can also be made of lightweight materials, such as aluminum alloy. Combined with its cavity structure design, it can further reduce weight. At the same time, modular design can reduce the number of parts and achieve cost control. When the second rod 3 is designed to be multiple and spaced along the first direction (i.e., the length direction of the vehicle), this design further promotes the implementation of the modular concept. The frame layout and width may be different for different models and different working conditions. By adjusting the number and spacing of the second rod 3, the side protection requirements of various vehicles can be flexibly matched. This modular design not only improves assembly efficiency and reduces production cycle, but also reduces inventory costs, because fewer types of parts mean simpler and more economical supply chain management.
[0053] Improving pedaling safety: The addition of the second rod 3 provides more support points for pedaling, especially in the length direction of the vehicle, so that the user can pedal more safely and conveniently at multiple positions, thereby improving the safety and convenience of the user getting on and off the vehicle.
[0054] Enhanced regulatory compliance: On the basis of meeting the requirements of the side protection regulations, the design of the second rod 3 can further optimize the structure to ensure that the vehicle can comply with relevant safety standards and specifications under different vehicle models and different working conditions.
[0055] Therefore, by adding the second rod 3 and connecting it with the first rod 1, not only the strength and stability of the side protection structure are increased, but also the modularity of the entire system is improved, which is of great significance for improving the overall safety performance of the vehicle and reducing maintenance costs.
[0056] The addition of the second rod 3 not only enhances the stability of the structure, but also provides the vehicle with additional functions, such as an increase in pedaling support points. For the driver and passengers, the multi-point pedaling design improves the safety and convenience of getting on and off the vehicle, especially at night or in bad weather conditions, where stable pedaling points can reduce the risk of slipping and falling. In addition, the second rod 3 can also integrate other functions, such as LED lighting, warning lights or reflective strips, to further improve the nighttime visibility and safety of the vehicle.
[0057] Furthermore, the vehicle external auxiliary safety device also includes a first connecting component 6, which includes: a connecting member 63, the connecting member 63 is connected to at least one of the first rod 1 and the second rod 3; a connecting seat 61, the connecting seat 61 is connected to the longitudinal beam of the vehicle beam and / or the cross beam of the vehicle beam; a connecting pipe 62, one end of the connecting pipe 62 is connected to the connecting seat 61, and the other end of the connecting pipe 62 is connected to the connecting member 63.
[0058] As one of the core components of the first connecting assembly 6, the connecting member 63 is used to directly connect at least one of the first rod 1 and the second rod 3, or to connect both of them at the same time. This design takes into account the effects of forces of different types and directions, ensuring a firm connection between the side protection structure and the vehicle body, and maintaining the integrity of the structure even in high-speed driving or collision. The connecting member 63 is usually made of high-strength materials, such as high-strength steel or alloy, to withstand lateral impact and vehicle vibration. Its design may include a variety of connection methods, such as bolt connection, welding or clamping, to facilitate on-site assembly and maintenance.
[0059] The connecting seat 61 is another key component in the first connecting assembly 6. Its function is to firmly connect the entire side protection structure with the longitudinal beam and / or cross beam of the vehicle beam. The design of the connecting seat 61 needs to take into account the effects of various forces during the vehicle's driving process, including but not limited to lateral force, longitudinal force and torsional force, to ensure the stability and reliability of the connection. In terms of material selection, the connecting seat 61 is usually made by forging or casting process to obtain excellent mechanical properties and fatigue resistance. Its connection method may include bolting, welding or special connection technology to adapt to different types of vehicle beam structures.
[0060] The connecting pipe 62 is used as a transition and connection tool, one end of which is connected to the connecting seat 61 and the other end is connected to the connecting piece 63. The design of the connecting pipe 62 is flexible and can adopt a cavity structure, which not only ensures sufficient strength but also achieves lightness. Its L-shaped or U-shaped design can effectively adapt to the complex spatial relationship between the side protection structure and the vehicle body, ensuring the optimization of the connection path. The connecting pipe 62 may also include a thickened or reinforced rib design to increase its bending and torsion resistance, ensuring that the connecting pipe 62 will not deform or break when the vehicle is subjected to lateral force.
[0061] The design of the first connecting assembly 6 ensures a stable mechanical connection between the vehicle's external auxiliary safety device and the vehicle body, which is essential for improving the safety of the vehicle in a side collision. The coordinated work of the connecting piece 63, the connecting seat 61 and the connecting pipe 62 not only realizes the modular assembly of the side protection structure, but also ensures the versatility and flexibility under different vehicle models and chassis layouts.
[0062] The first connection assembly 6 simplifies the assembly process through standardized connecting parts and connecting seats, reduces the time and difficulty of on-site assembly, and improves production efficiency.
[0063] The modular connection design allows the fault point to be quickly located when minor damage occurs. Only the corresponding connection components need to be replaced, without the need to dismantle the entire side protection structure on a large scale, reducing maintenance costs and time.
[0064] By optimizing the material, structure and connection method of the connection component, the first connection component 6 can withstand higher loads, ensuring that in extreme cases, the side protection structure is still firmly fixed to the vehicle, providing continuous protection for the occupants and the vehicle.
[0065] The cavity structure design of the connecting pipe 62 and the efficient material use of the connecting piece 63 help to control the overall weight and reduce material costs. At the same time, the modular design reduces the types of parts in the production process, simplifies supply chain management, and reduces the total cost.
[0066] In summary, the design of the first connecting component 6 is the cornerstone of the stable connection between the vehicle's external auxiliary safety device and the vehicle body. It not only improves the functionality and safety of the side protection structure, but also optimizes the assembly and maintenance process. It reflects the comprehensive consideration of safety, efficiency and cost control in modern vehicle engineering, and is an important innovation in vehicle side protection technology.
[0067] Furthermore, the connecting pipe 62 includes a first pipe segment and a second pipe segment, the first pipe segment and the second pipe segment are connected, and an angle is set between the first pipe segment and the second pipe segment. An envelope space is formed inside the connecting piece 63, the first pipe segment is located in the envelope space, and the end of the second pipe segment away from the first pipe segment is connected to the connecting seat 61.
[0068] The connecting pipe 62 is composed of a first pipe section and a second pipe section. The angle between the two sections is designed to solve the problem of complex external structure and space limitation of the vehicle. This design allows the connecting pipe 62 to connect the side protection structure and the vehicle beam in an L-shape or other angles, effectively utilizing the space on the side of the vehicle. At the same time, the angle setting also increases the rigidity of the structure and reduces the possibility of deformation under lateral and longitudinal loads. The first pipe section is connected to the first rod 1 or the second rod 3 of the side protection structure, while the second pipe section is connected to the connecting seat 61 of the vehicle beam. This connection method ensures that the force transmission path is optimized and improves the efficiency of the entire connection structure.
[0069] The connector 63 is designed with an envelope space inside, a detail that takes into account the convenience of fixing and assembling the connecting pipe 62. The first pipe section is located in the envelope space, which not only protects the connecting pipe 62 from external damage, but also ensures accurate alignment and tight connection between the pipe section and the connector, thereby improving the stability and reliability of the connection. The design of the envelope space may include a groove that matches the shape of the first pipe section, as well as a threaded hole or a slot for fastening. Through these designs, the connector 63 can firmly fix the first pipe section inside it, forming a strong connection point.
[0070] By placing the first pipe section in the envelope space of the connector 63 and directly connecting the second pipe section to the connector seat 61, the assembly process of the first connector assembly 6 becomes simpler and faster. This design allows the side protection structure to be easily installed and removed without damaging other parts of the vehicle, thereby providing great convenience for on-site assembly and subsequent maintenance. In addition, if any part of the connector pipe 62 is damaged, only the part can be replaced without removing the entire side protection structure, reducing maintenance costs and time.
[0071] The first pipe section and the second pipe section are usually made of high-strength and lightweight materials, such as aluminum alloy or stainless steel, to balance the structural strength and the vehicle lightweight requirements. The connection method of the connecting pipe 62, such as welding or bolting, needs to be carefully selected according to the material properties and connection requirements. For example, for aluminum alloy pipe sections, friction welding or laser welding may provide a more reliable connection, while for stainless steel, bolting may be more preferred to avoid potential changes in material properties during welding.
[0072] The design of the specific angle and envelope space of the connecting tube 62 needs to be optimized through engineering analysis and simulation software to ensure the strength and stability of the connection point under various working conditions. In addition, the length, diameter and wall thickness of the connecting tube 62 also need to be carefully calculated to achieve the best weight and strength ratio. In vehicle collision tests and durability tests, these design details will directly affect the performance of the side protection structure, as well as the overall safety and driving experience of the vehicle.
[0073] When designing the connecting pipe 62 and its components, relevant vehicle design standards and safety regulations must be strictly followed. The setting of angles, the selection of materials, and the connection method must ensure that the side protection structure can meet the requirements of the collision test, especially in terms of side collision safety performance. In addition, the design of the connecting pipe 62 should also take into account the aesthetics and aerodynamics of the vehicle to avoid negative impacts on the appearance and driving efficiency of the vehicle.
[0074] In summary, the specific design of the connecting pipe 62, including the angle between the first pipe section and the second pipe section and the envelope space of the connecting piece 63, not only optimizes the connection between the side protection structure and the vehicle body, but also improves the strength, stability and maintenance convenience of the entire connecting assembly.
[0075] Furthermore, the vehicle bottom accessory includes a urea tank bracket 30, and the vehicle external auxiliary safety device also includes a second connecting component, which includes: a transition bracket 5, which is connected to at least one of the first rod 1 and the second rod 3; a connecting bracket 4, one end of the connecting bracket 4 is connected to the transition bracket 5, and the other end of the connecting bracket 4 is connected to the urea tank bracket 30.
[0076] like Figure 2 As shown, the transition bracket 5 includes a first transition section 54 and a second transition section 55, the first transition section 54 and the second transition section 55 are connected, and the first transition section 54 and the second transition section 55 are arranged at an angle, the first transition section 54 is connected to at least one of the first rod 1 and the second rod 3, and the second transition section 55 is connected to the connecting bracket 4, and the transition bracket 5 also includes at least one first reinforcing rib 53, and the first reinforcing rib 53 is connected to both the first transition section 54 and the second transition section 55.
[0077] Optionally, the first transition section 54 and the second transition section 55 are vertically arranged, and the surface of the first transition section 54 is tightly fitted to at least one of the first rod 1 and the second rod 3 .
[0078] Optionally, there are multiple first reinforcing ribs 53, and the multiple first reinforcing ribs 53 are arranged at intervals along the height direction.
[0079] Optionally, the height of the first reinforcing rib 53 is gradually reduced from the first transition section 54 to the second transition section 55 .
[0080] The first reinforcing rib 53 is preferably a triangular reinforcing rib.
[0081] The width of the first transition section 54 is smaller than that of the second transition section 55 , and the two have the same height. The width of the first transition section 54 is equal to the width of the second rod.
[0082] Furthermore, the first rod member 1 is a rod member structure having a cavity inside, and at least one end of the first rod member 1 in the length direction is connected to the end cover, and the end cover includes a sealing plate 21 and a surrounding plate 22, one end of the surrounding plate 22 is connected to the sealing plate 21, and the other end of the surrounding plate 22 is extended away from the sealing plate 21, wherein the sealing plate 21 blocks the opening of the cavity, and the surrounding plate 22 extends into the interior of the cavity, and the surrounding plate 22 is arranged to form an annular structure.
[0083] The first rod 1 of the cavity design uses the shape of the material rather than its density to enhance its physical properties. This structure can provide sufficient rigidity and bending resistance while significantly reducing the use of materials, thereby reducing the overall weight. In vehicle design, structural lightweighting is crucial to improving fuel efficiency, reducing emissions, and improving handling and driving economy. The use of lightweight and high-strength materials such as aluminum alloys can further optimize this effect.
[0084] The end cap closes the opening of the cavity of the first rod 1 through the sealing plate 21, ensuring the integrity of the internal structure, preventing pollutants and moisture from entering, and extending the service life of the rod. The enclosure 22 extends into the cavity to form an annular structure. This design increases the contact area between the end cap and the rod. Through the enveloping effect of the enclosure 22, the mechanical connection between the end cap and the first rod 1 is further strengthened, ensuring the strength and stability of the connection.
[0085] By matching the end cap with the cavity structure of the first rod 1, a modular design concept is realized. The standardized design of the end cap allows it to be connected to the first rod 1 of different lengths and diameters, so that the side protection structure can be flexibly adapted to a variety of vehicle models and chassis layouts, improving assembly efficiency and design versatility. In addition, the standardized end cap design also helps reduce manufacturing costs and the complexity of supply chain management.
[0086] The special design of the end caps, including the R3 rounded corners and other regulatory features, ensures that the side protection structure not only meets the requirements in terms of physical performance, but also complies with the safety regulations of various countries. For example, the R3 rounded corners can reduce the damage to pedestrians or cyclists in a collision, which is a mandatory safety feature in many regional regulations.
[0087] The first rod 1 of the cavity structure and the firmly connected end cap work together to form a side protection system that can absorb impact force while maintaining structural integrity. In the event of a side collision, this design can effectively protect the vehicle tank and passenger compartment, reduce injuries, and meet strict collision safety test requirements.
[0088] The end cap 22 is interference fit with the inner cavity of the first rod 1, which simplifies the assembly process, does not require complicated welding or additional fasteners, and reduces assembly cost and time. In addition, the sealing effect of the sealing plate 21 also simplifies subsequent maintenance and inspection work, reducing maintenance costs during the vehicle life cycle.
[0089] The neat design of the end cap and the close fit with the first rod 1 not only improve the appearance of the side of the vehicle, but also help optimize the aerodynamic performance. The protruding parts on the side of the vehicle are reduced, the air resistance and noise are reduced, and the driving efficiency and comfort of the vehicle are improved.
[0090] The combination of the end cap and the first rod 1 can also integrate other functions, such as signal lights, lighting or warning signs, to further enhance the safety and functionality of the vehicle without adding additional external components, thus maintaining the simplicity and beauty of the vehicle side.
[0091] Furthermore, a wedge-shaped portion 23 is provided on the outer wall of the enclosure 22, and the wedge-shaped portion 23 is adaptively arranged with the inner wall structure of the cavity in the first rod 1. At least one second reinforcing rib 24 is provided on the inner wall of the enclosure 22, and the second reinforcing rib 24 is connected to both the sealing plate 21 and the enclosure 22.
[0092] Furthermore, a slide rail is provided on the second rod 3, and a slider is provided on at least one of the two first rods 1. The first rod 1 provided with the slider is movably arranged along the second direction relative to the other first rods 1, so that the size of the first pedaling space 10 can be adjusted.
[0093] Furthermore, each first rod member 1 is connected to the second rod member 3 through a corresponding telescopic assembly, and the telescopic assembly is adjustable in length along the third direction so that the distance between each first rod member 1 and the second rod member 3 is set differently, wherein the third direction is perpendicular to both the first direction and the second direction.
[0094] The core of the telescopic assembly is that it can be designed to be adjustable in length along the third direction (i.e., the vertical direction of the vehicle). This design is achieved by including multiple sleeves (such as an outer sleeve and an inner sleeve), wherein the inner sleeve can be telescopically installed inside the outer sleeve. By adjusting the telescopic length of the inner sleeve relative to the outer sleeve, the vertical distance between the first rod 1 and the second rod 3 can be flexibly adjusted, thereby adapting to the chassis height of different vehicles and the installation requirements of the side protection structure.
[0095] The adjustment mechanism of the telescopic assembly can be implemented in a variety of ways to ensure the accuracy and safety of the adjustment process:
[0096] Manual adjustment: Designed with an easy-to-operate handle or knob, the driver or maintenance personnel can manually adjust the length of the telescopic component. This design is simple and direct and is suitable for scenarios where frequent adjustment is not required.
[0097] Electric adjustment: Equipped with an electric motor and control unit, the length of the telescopic component can be adjusted through the vehicle system or a dedicated remote control, which improves the convenience and accuracy of adjustment and is suitable for applications that require dynamic adjustment or remote control.
[0098] Pneumatic or hydraulic adjustment: Use air pressure or hydraulic system to adjust the length of the telescopic component. This adjustment method can provide a smoother extension and retraction process and is suitable for adjustment scenarios that require high precision and stability, such as automatically adjusting the height of the side guard structure when the vehicle load changes.
[0099] In order to ensure that the telescopic assembly can remain stable and safe during vehicle driving and collision, the design needs to consider the following key points: Locking mechanism: Whether manual, electric or pneumatic / hydraulic adjustment is used, the telescopic assembly should be equipped with a reliable locking mechanism, such as a locking nut, electromagnetic lock or hydraulic lock, to prevent accidental extension or loosening due to vibration or impact during driving.
[0100] Limit device: Set physical or electronic limiters to prevent the telescopic component from over-expanding or contracting, ensure that it works within a safe range, and avoid damage to the side protection structure or the vehicle body.
[0101] The sleeve is manufactured using high-strength materials and precision processing technology to ensure the structural strength and rigidity of the telescopic assembly when subjected to lateral forces and to prevent deformation or damage of the sleeve.
[0102] The sleeves and connectors of the telescopic assembly should be treated with anti-corrosion and weather-resistant treatments, such as surface coating, spraying or special material selection, to ensure good performance and service life under various harsh environmental conditions.
[0103] In an optional embodiment, the side protection structure includes a first rod, an end cover, a second rod, a front connecting bracket, a transition bracket and a rear connecting bracket.

The cross section of the second rod is an aluminum profile cavity structure, which is light in weight, and is provided with mounting holes for fixing the transition bracket and the rear connecting bracket, and is also provided with avoidance holes for reserving space for convenient bolt fixing; by setting the X-direction spacing value between different second rods and the Z-direction spacing of different mounting holes on the same second rod, the connection of the connecting brackets arranged in different chassis can be matched to achieve modular design. The front connecting bracket is a flat plate structure, including an upper mounting hole, a lower mounting hole and a weight-reducing hole; the upper mounting hole is used to fix the urea tank bracket, the lower mounting hole is used to fix the transition bracket, and the weight-reducing hole is used to reduce weight to achieve lightweight. The transition bracket is an L-shaped bracket and a flat plate welded structure, which is provided with a mounting hole for connecting and fixing with the lower mounting hole of the front connecting bracket, and is also provided with a mounting hole for connecting and fixing with the mounting hole on the second rod member through a bolt assembly, and is also provided with a reinforcing rib for structural reinforcement. The rear connecting bracket is a pipe beam welding assembly structure, including a base, a connecting pipe and a U-shaped pipe; the base is a forging with good process performance, and is provided with a mounting hole on one end, which is connected and fixed with the longitudinal beam through a bolt assembly, and the other end is welded and fixed with the connecting pipe by a friction welding process to achieve a reliable connection; the connecting pipe is a cavity structure, L-shaped, and plays a transition connection role, which is used to connect the base and the U-shaped plate; one end of the U-shaped plate is covered and welded to the connecting pipe, and the other end is provided with a mounting hole for connecting and fixing with the mounting hole on the second rod member.
[0104] The assembly process of the side protection structure is as follows: (1) The front connecting bracket and the transition bracket are integrally connected and fixed to the urea tank bracket, and the rear connecting bracket is fixed to the longitudinal beam of the frame, and the whole is composed of an assembly subassembly. (2) The first rod, the end cover and the second rod are assembled together to form an assembly subassembly. (3) The assembly subassembly is assembled with the assembly subassembly, and the connecting bolts are fixed from the outside through the avoidance hole. The overall connection is reliable and easy to disassemble and assemble.
[0105] The first rod can realize the pedaling function at any position and can replace the original pedaling ladder structure.
[0106] In order to achieve the above objective, according to one aspect of the present invention, a vehicle is provided, including a vehicle external auxiliary safety device such as the above vehicle external auxiliary safety device.
[0107] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:
[0108] The technical solution of this application solves the problems of low reliability, heavy weight, complex assembly and high cost of the side protection structure, and improves the safety and economy of the tractor. By adopting crossbars, end covers, vertical bars and connecting brackets with specific structures, the stability and reliability of the overall structure are enhanced to ensure that the vehicle and fuel tank can be effectively protected in the event of a side collision; the crossbars and vertical bars with aluminum profile cavity structures and ABS injection molded end covers are used to reduce the total weight of the side protection structure; by adjusting the X-direction spacing value between the vertical bars and the Z-direction spacing of the mounting holes on the same vertical bar, the design can flexibly match different chassis layouts to achieve modular assembly; the pedaling function is integrated into the side protection crossbar, replacing the original dedicated pedaling ladder, realizing functional integration and further reducing costs.
[0109] This solution significantly reduces weight by using a crossbar made of an aluminum profile crossbeam and a vertical bar with a cavity structure. At the same time, the weight-reducing hole design of the front connecting bracket further reduces the weight of the overall structure, which helps to improve the vehicle's fuel economy and driving performance. The wedge-shaped design of the end cover cooperates with the internal cavity of the crossbar, and a certain interference fit ensures a tight connection and structural stability between the two. The base of the rear connecting bracket is made of forged parts and connected to the connecting pipe by friction welding, which ensures the reliability and durability of the connection. By adjusting the spacing between different vertical bars and the spacing between different mounting holes on the same vertical bar, the side protection structure can adapt to connecting brackets with different chassis arrangements, realizing a modular design and improving assembly efficiency and versatility. The crossbar can realize the pedaling function at any position, which not only simplifies the structure of the vehicle side, but also reduces costs.
