[0039] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0040] The core of this utility model is to provide a vehicle anti-collision device and a vehicle, which can effectively reduce the difficulty of production and manufacturing and control costs.
[0041] To enable those skilled in the art to better understand the technical solutions provided by this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0042] For details, please refer to Figures 1-10 The present invention provides a vehicle anti-collision device, comprising a main curved beam 1, a main cross beam 2, two first vertical support curved beams 3, a curved beam base beam 5, and an anti-collision bar mounting beam 6.
[0043] The main curved beam 1 is circular in shape and has an installation notch, which is used to connect the main crossbeam 2 to form a complete circular structure. The main curved beam 1 adopts an integral structure and has a certain structural strength.
[0044] Both ends of the main curved beam 1 are welded to the middle sections of the two first vertical support curved beams 3, respectively. The installation notch is located between the two ends of the main curved beam 1. The first vertical support curved beams 3 can provide support for the cantilever section of the main curved beam 1 near the end. One end of each first vertical support curved beam 3 is welded to one side of the curved beam base beam 5, and the other end is welded to the main curved beam 1 on the opposite side of the installation notch.
[0045] The main crossbeam 2 is set between the installation gaps, and both ends of the main crossbeam 2 are welded to the two first vertical support beams 3 respectively.
[0046] On the other side of the curved beam base beam 5, a crash bar mounting beam 6 is provided, which is used to mount the vehicle crash protection device to the vehicle frame. To improve the ease of installation, the crash bar mounting beam 6 is designed for detachable connection to the vehicle frame.
[0047] The vehicle collision avoidance device provided in this solution utilizes a main curved beam 1, a main crossbeam 2, two first vertical support curved beams 3, and a curved beam base beam 5 to form a frame structure for resisting external impacts. It is connected to the vehicle frame via a collision avoidance rod mounting beam 6. The various components of the vehicle collision avoidance device are welded together to form a welded assembly, which is then installed on the vehicle frame. This manufacturing method is easy to implement, offers high stability, and effectively reduces production difficulty and controls costs.
[0048] This case also includes a second vertical support beam 4 welded to the main crossbeam 2 and the curved beam base beam 5 respectively. The second vertical support beam 4 can further provide effective support for the main crossbeam 2 and improve the structural strength of the entire vehicle anti-collision device.
[0049] In a specific embodiment, multiple embedding holes 501 can be formed on the curved beam base beam 5. One end of the first vertical support curved beam 3 and / or the second vertical support curved beam 4 passes through the embedding hole 501 of the curved beam base beam 5, and the first vertical support curved beam 3 and / or the second vertical support curved beam 4 are welded to the curved beam base beam 5. See [reference needed]. Figure 9 Specifically, the first vertical support beam 3 and the second vertical support beam 4 can be welded to the front, rear and inner sides of the embedding hole 501 of the beam base beam 5 using welding rods.
[0050] Correspondingly, the other end of the first vertical support beam 3 and / or the second vertical support beam 4 passes through the main body beam 1 and is welded. That is, multiple embedding holes can be opened on the main body beam 1, the other end of the first vertical support beam 3 and / or the second vertical support beam 4 passes through the embedding holes of the main body beam 1, and the first vertical support beam 3 and / or the second vertical support beam 4 are welded to the main body beam 1. In particular, the first vertical support beam 3 / second vertical support beam 4 can be welded to the front, rear and inner sides of the embedding holes of the main body beam 1 using welding rods.
[0051] The above configuration allows for both embedded snap-fit and welding connections at the ends of the first vertical support beam 3 and / or the second vertical support beam 4, thereby further improving the connection strength at the ends.
[0052] The welding connection method is convenient to operate, has mature technology, and has reliable strength.
[0053] In a specific embodiment, such as Figure 7 and Figure 8 As shown, both the first vertical support beam 3 and the second vertical support beam 4 are J-shaped, including a vertical section and a curved section. The vertical sections of the first vertical support beam 3 and the second vertical support beam 4 are welded to the main curved beam 1. The vertical sections of the first vertical support beam 3 and the second vertical support beam 4, together with the main curved beam 1 and the main crossbeam 2, form a vertical plane perpendicular to the ground (see...). Figure 5 The curved sections of the first vertical support beam 3 and the second vertical support beam 4 are welded to the base beam 5. These curved sections suspend the vertical plane formed by the main beam 1 and the main crossbeam 2, and are spaced a distance from the side of the frame. This provides a certain degree of cushioning, effectively reducing collision damage to the vehicle body and significantly saving on repair time and costs.
[0054] The curved section connecting the first vertical support beam 3 / second vertical support beam 4 and the curved beam base beam 5 can actually be regarded as a straight section, so as to better insert it into the embedding hole 501 of the curved beam base beam 5, thereby making the installation convenient and the connection stable.
[0055] To improve the stability of the connection, there are multiple second vertical support beams 4, which are arranged at intervals.
[0056] In a specific embodiment, this solution also includes a reinforcing rib 7 connecting the curved beam base beam 5 and the anti-collision bar mounting beam 6. The reinforcing rib 7 can enhance the yield strength and effectively prevent stress concentration that could lead to component failure.
[0057] To facilitate disassembly and assembly, the anti-collision bar mounting beam 6 is provided with threaded holes for bolt connection to the vehicle frame. Specifically, the two threaded holes on the anti-collision bar mounting beam 6 are M10 bolt assembly mounting holes, making the entire vehicle anti-collision device easy to install and operate.
[0058] In a specific embodiment, the components of the vehicle anti-collision device are made of extruded lightweight metal profiles. All components of the vehicle anti-collision device are Q235 steel structures. Of course, the design, materials, and installation method of the vehicle anti-collision device may vary depending on the vehicle type and purpose. The vehicle anti-collision device can be installed at any location on the vehicle body prone to collision. The structure of the main curved beam 1 and the anti-collision bar mounting beam 6 may vary depending on the actual frame area where the anti-collision device is installed.
[0059] This solution addresses the problem of vehicles requiring anti-collision devices but lacking a rapid response time. It can be completed by welding and reinforcing parts obtained through simple methods. The device has a robust structure, saves time and effort, and is highly efficient and convenient.
[0060] It should be noted that the cross-sectional shape, thickness, and length of the aforementioned main curved beam 1, main horizontal beam 2, first vertical support curved beam 3, second vertical support curved beam 4, curved beam base beam 5, anti-collision bar mounting beam 6, and reinforcing rib 7 need to be determined through precise calculation and simulation analysis. Common cross-sectional shapes for the main curved beam 1, main horizontal beam 2, first vertical support curved beam 3, and second vertical support curved beam 4 include circular and rectangular shapes. Common cross-sectional shapes for the curved beam base beam 5, anti-collision bar mounting beam 6, and reinforcing rib 7 include rectangular, T-shaped, and I-shaped shapes, with different shapes having varying effects on stress distribution and yield strength. These parameters are optimized through finite element analysis and other methods to achieve the best mechanical performance improvement while also considering the feasibility of manufacturing processes and cost control.
[0061] The connection method of the above components is crucial and can be achieved through welding, riveting, bolting, or bonding. Different connection methods have their own advantages and disadvantages in terms of connection strength, process complexity, cost, and impact on the overall structural performance. It is necessary to comprehensively consider factors such as structural characteristics, usage requirements, and manufacturing conditions to select the most suitable connection method, ensuring that the two connected components can function effectively and form a robust and stable integrated structure.
[0062] This utility model also provides a vehicle, including the vehicle anti-collision device as described in the above specific embodiments.
[0063] Obviously, vehicles equipped with the aforementioned collision avoidance devices have the same beneficial effects, which will not be elaborated upon here.
[0064] The vehicle collision avoidance device provided in this solution overcomes the technical bottlenecks of traditional collision avoidance devices. While ensuring collision safety performance, it breaks free from reliance on high-cost materials, simplifies manufacturing processes, and improves product versatility. It boasts advantages such as rational space utilization, low development costs, short development cycles, and rapid market response. It is particularly suitable for sightseeing vehicles within scenic areas.
