Description

Technical Field

[0001] This utility model relates to the field of side protection structure technology, and in particular to a side protection structure and vehicle. Background Technology

[0002] In modern truck safety design systems, in accordance with national safety regulations and industry standards, side protection structures must be installed on the front side of trucks to ensure vehicle driving safety. At the same time, these side protection structures also serve as foot pedals for drivers to use when getting in and out of the vehicle. Therefore, their rigidity and strength in the horizontal and vertical directions must strictly meet the performance requirements stipulated by national standards.

[0003] Traditional truck frontal protection devices often employ a simple frame structure, primarily consisting of multiple transverse support beams and longitudinal columns connected by welding or bolts. This structure cannot effectively disperse impact forces during lateral collisions, easily leading to structural deformation or even damage. Consequently, the vehicle's lateral safety is low, making it difficult to guarantee driving safety. Furthermore, to meet the stringent rigidity and strength requirements of national standards, it is often necessary to continuously increase the size and wall thickness of the support beams and columns, resulting in a bulky and cumbersome overall structure. This not only makes installation and disassembly on the vehicle body complex and reduces versatility but also increases the overall operating energy consumption of the vehicle, limits cargo loading space, and reduces transportation efficiency. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a side protection structure and vehicle, which aims to solve the technical problems of traditional truck front side protection devices, which mostly adopt simple frame structures, cannot effectively disperse impact force when subjected to side impact, and are prone to structural deformation or even damage, resulting in low lateral safety of the vehicle, difficulty in ensuring the driving safety of the vehicle, and bulky and low versatility of the overall structure.

[0005] One aspect of this utility model is to provide a side protection structure, comprising:

[0006] The first bracket includes an end cap and two connecting rods connected to the end cap, the two connecting rods being parallel to each other;

[0007] The second bracket includes a connecting plate and a protective plate. The protective plate extends around the outer contour of the connecting plate and is perpendicular to the connecting plate. The connecting plate is provided with two first through holes, which are spaced apart along the length of the connecting plate. The connecting rod passes through and is fixed in the first through holes to realize the connection between the first bracket and the second bracket.

[0008] The connecting plate has multiple reinforcing ribs on its surface. The reinforcing ribs extend along the length or width of the connecting plate, and the ends of the reinforcing ribs are connected to the surface of the protective plate.

[0009] Furthermore, along the length of the connecting plate, the connecting plate includes an integrally formed first connecting segment, a transition segment, and a second connecting segment. The thickness of the first connecting segment is less than the thickness of the second connecting segment. The first connecting segment is provided with a first through hole, and the second connecting segment is provided with at least two second through holes.

[0010] Furthermore, the thickness of the first connecting segment is 6mm-16mm, and the thickness of the second connecting segment is 18mm-28mm.

[0011] Furthermore, the outer contour edge of the connecting plate is integrally connected to the middle plate surface of the protective plate in the width direction. The two side plates of the connecting plate are respectively provided with the reinforcing ribs. The thickness of the reinforcing ribs is the same as the thickness of the protective plate, and the end face of the reinforcing rib away from the connecting plate is lower than or flush with the end face of the protective plate.

[0012] Furthermore, the distance between the end face of the protective plate and the surface of the connecting plate is 26mm-32mm, and the thickness of the protective plate is 15mm-25mm.

[0013] Furthermore, the side protection structure also includes a third bracket, which includes a mounting plate and a fixing plate connected to the mounting plate. The mounting plate is provided with at least two connecting blocks, and the connecting blocks are provided with internal threaded holes. The mounting plate is provided with guide holes communicating with the internal threaded holes. A first bolt is threaded through the second through hole, the guide hole and the internal threaded hole in sequence to achieve the connection between the third bracket and the second bracket.

[0014] Furthermore, both the mounting plate and the fixing plate are L-shaped plate structures. The connecting block is provided on the inner side of one side plate of the mounting plate, and the outer side of the other side plate of the mounting plate is fixedly connected to the outer side of one side plate of the fixing plate by welding.

[0015] The third bracket also includes at least one reinforcing plate, the two ends of which are fixedly connected to the inner side surfaces of the two side plates on the mounting plate by welding.

[0016] Furthermore, the mounting plate has at least two second bolts on one side plate connected to the fixing plate, and the fixing plate has at least one third bolt on the other side plate. The second bolts and the third bolts are respectively screwed to the preset mounting points on the vehicle to install the side protection structure in the preset position of the vehicle.

[0017] Furthermore, the end cap includes a first cover plate and a second cover plate extending perpendicularly outward from both ends of the first cover plate. The first cover plate is an arc-shaped plate structure. One end of the connecting rod is fixedly connected to the surface of the first cover plate and the second cover plate by welding.

[0018] Another aspect of this utility model is to provide a vehicle including the aforementioned side protection structure.

[0019] Compared to existing technologies, the beneficial effects of this utility model's side protection structure and vehicle are as follows: Through the coordinated operation of the first and second supports of this application, the impact force can be effectively absorbed and dispersed when the vehicle is subjected to a side impact, reducing damage to the vehicle's side and significantly improving vehicle driving safety. Specifically, the first support adopts an arc-shaped end cap and a hollow square tubular connecting rod. The arc design can effectively disperse the side impact force, avoid stress concentration, and enhance impact resistance. The hollow square tubular structure has good compressive and torsional resistance, and is firmly connected to the end cap by welding, improving overall stability. Furthermore, the connecting plate of the second support adopts a differentiated plate thickness design, combined with an integrally formed reinforcing rib and transition section design, which can reasonably distribute strength, prevent stress concentration, and enhance the rigidity and strength of the connecting plate. Moreover, the protective plate of the second support is arranged around the outer contour of the connecting plate and vertically, forming a comprehensive three-dimensional protection system together with the crisscrossing reinforcing ribs, which can effectively protect the side of the vehicle. Furthermore, this application also includes a third bracket that is threadedly connected to a pre-set mounting point on the vehicle via multiple bolts. The entire blood collection and installation operation is convenient, and it is easy to disassemble and replace a single component without having to disassemble the entire structure on a large scale, which improves maintenance efficiency and reduces maintenance difficulty and cost.

Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] Please see Figures 1 to 6The diagram illustrates a side protection structure of this utility model, comprising a first bracket 10, a second bracket 20 connected to the first bracket 10, and a third bracket 30 connected to the second bracket 20. The first bracket 10 includes an end cap 11 and two connecting rods 12 connected to the end cap 11, the two connecting rods 12 being parallel to each other. Specifically, the end cap 11 includes a first cover plate 111 and second cover plates 112 extending vertically outward from both ends of the first cover plate 111. The first cover plate 111 has an arc-shaped plate structure; this arc design can better disperse impact force and avoid stress concentration during lateral impacts, providing stronger impact resistance compared to a planar structure. One end of each connecting rod 12 is fixedly connected to the surfaces of the first cover plate 111 and the second cover plate 112 by welding. The connecting rod 12 has a hollow square tubular structure to effectively reduce structural weight and vehicle load.

[0032] As an example, the second bracket 20 includes a connecting plate 21 and a protective plate 22. The protective plate 22 extends around the outer contour of the connecting plate 21 and is perpendicular to the connecting plate 21 to form a three-dimensional protective space, improving the protection performance of the vehicle side. The connecting plate 21 is provided with two first through holes 201, which are spaced apart along the length of the connecting plate 21. The connecting rod 12 passes through and is fixed in the first through hole 201 by welding to realize the connection between the first bracket 10 and the second bracket 20. Specifically, along the length of the connecting plate 21, the connecting plate 21 includes an integrally formed first connecting section 211, a transition section 212, and a second connecting section 213. The thickness of the first connecting section 211 is smaller than that of the second connecting section 213. It should be understood that the first connecting section 211 is mainly used to connect with the connecting rod 12 of the first bracket 10. The relatively smaller plate thickness can effectively reduce the overall weight while ensuring the connection strength. The second connecting section 213 needs to be fitted with a first bolt 41 to achieve the connection with the third bracket 30. The larger plate thickness can provide sufficient strength and stability, thereby ensuring the reliability of the connection. The first connecting section 211 is provided with two first through holes 201, which are adapted to the connecting rod 12. The first through holes 201 are square holes. One of the first through holes 201 is located at the end of the first connecting section 211, and the other first through hole 201 is located in the middle region along the length of the first connecting section 211. The second connecting section 213 is provided with at least two second through holes 202, which are used to install the first bolt 41.

[0033] Furthermore, the thickness of the first connecting section 211 is 6mm-16mm, the thickness of the second connecting section 213 is 18mm-28mm, and the thickness of the transition section 212 gradually increases from the first connecting section 211 to the second connecting section 213. The gradual design of the transition section 212 can effectively avoid stress concentration caused by sudden changes in thickness, and improve the overall strength and service life of the connecting plate 21.

[0034] Furthermore, the connecting plate 21 is provided with a plurality of reinforcing ribs 23 on its surface. The reinforcing ribs 23 extend along the length or width of the connecting plate 21, and the ends of the reinforcing ribs 23 are connected to the surface of the protective plate 22. In this embodiment, the reinforcing ribs 23, the connecting plate 21, and the protective plate 22 are integrally formed to ensure the connection strength between the reinforcing ribs 23 and the connecting plate 21 and the protective plate 22, and to avoid affecting the overall performance due to gaps or weak points in the connection parts. The reinforcing ribs 23 include a first rib and a second rib. The first rib is arranged along the length of the connecting plate 21, and the second rib is arranged along the width of the connecting plate 21. This crisscrossing arrangement of the reinforcing ribs 23 can enhance the rigidity and strength of the connecting plate 21 from multiple directions, effectively improving the deformation resistance of the second support 20.

[0035] Furthermore, the cross-sectional shape of the reinforcing rib 23 can be one of a triangle, a rectangle, or a trapezoid. As a specific example, in this embodiment, the cross-sectional shape of the reinforcing rib 23 is a rectangle.

[0036] Furthermore, the outer contour edge of the connecting plate 21 is integrally connected to the middle surface of the protective plate 22 in the width direction. Multiple reinforcing ribs 23 are provided on both sides of the connecting plate 21. The thickness of the reinforcing ribs 23 is the same as the thickness of the protective plate 22, and the end face of the reinforcing rib 23 furthest from the connecting plate 21 is lower than or flush with the end face of the protective plate 22. Even further, the distance between the end face of the protective plate 22 and the surface of the connecting plate 21 is 26mm-32mm, and the thickness of the protective plate 22 is 15mm-25mm.

[0037] The side protection structure of this application also includes a third bracket 30, which includes a mounting plate 31 and a fixing plate 32 connected to the mounting plate 31. The mounting plate 31 is provided with at least two connecting blocks 33, and the connecting blocks 33 are provided with internal threaded holes. The mounting plate 31 is provided with guide holes communicating with the internal threaded holes. The connection between the third bracket 30 and the second bracket 20 is realized by the first bolt 41 passing through the second through hole 202, the guide hole and the internal threaded hole in sequence.

[0038] Furthermore, both the mounting plate 31 and the fixing plate 32 are L-shaped plate structures. A connecting block 33 is provided on the inner side of one side plate of the mounting plate 31, and the outer side of the other side plate of the mounting plate 31 is fixedly connected to the outer side of one side plate of the fixing plate 32 by welding. This L-shaped structure design can increase the connection strength and stability of the mounting plate 31 and the fixing plate 32, and at the same time facilitates connection with the preset mounting points on the vehicle.

[0039] Furthermore, the third support 30 also includes at least one reinforcing plate 34. The two ends of the reinforcing plate 34 are fixedly connected to the inner side plates of the two side plates on the mounting plate 31 by welding. The setting of the reinforcing plate 34 can further enhance the structural strength of the third support 30 and improve its stability and reliability when subjected to external forces.

[0040] Furthermore, at least two second bolts 42 are provided on one side of the mounting plate 31 that is connected to the fixing plate 32, and at least one third bolt 43 is provided on the other side of the fixing plate 32. The second bolts 42 and the third bolt 43 are respectively screwed to the preset mounting points on the vehicle to install the side protection structure in the preset position of the vehicle.

[0041] Furthermore, the connecting rod 12 in the first bracket 10 is made of sheet molding compound (SMC) fiberglass, the end cap 11 in the first bracket 10 is made of polypropylene, the second bracket 20 is made of fiberglass, and the third bracket 30 is made of sheet metal. By using these lightweight materials of different materials, combined with the hollow design of the connecting rod 12 and the plate thickness design of different areas on the second bracket 20, the weight of the side protection structure is significantly reduced while ensuring overall strength, thereby reducing vehicle load, improving fuel economy and driving performance, reducing operating costs, and improving the applicability of the entire side protection structure.

[0042] In practical application, the installation steps of the side protection structure of this application are as follows: First, the connecting rod 12 of the first bracket 10 is passed through the first through hole 201 on the connecting plate 21 of the second bracket 20 and fixed by welding; then, the first bolt 41 is passed through the second through hole 202 on the connecting plate 21 of the second bracket 20 and the guide hole on the mounting plate 31 of the third bracket 30 in sequence, and is threadedly connected to the internal threaded hole of the connecting block 33 on the mounting plate 31 to realize the connection between the second bracket 20 and the third bracket 30; finally, the mounting plate 31 and the fixing plate 32 of the third bracket 30 are screwed to the preset installation point on the vehicle by the second bolt 42 and the third bolt 43 to complete the installation of the side protection structure on the vehicle. After installation, the side protection structure is thoroughly inspected to ensure that all components are firmly connected and there is no looseness, so as to ensure that the side protection structure can play a normal protective role.

[0043] This application also provides a vehicle that includes the aforementioned side protection structure. Applying the side protection structure of this application to a vehicle can significantly improve the vehicle's lateral safety protection performance and reduce the damage to the vehicle and personnel caused by lateral collision accidents, thus having good application prospects and practical value.

[0044] In summary, the beneficial effects of the side protection structure of this utility model are as follows: through the coordinated operation of the first and second brackets of this application, the impact force can be effectively absorbed and dispersed when the vehicle is subjected to a side impact, reducing the damage to the side of the vehicle and significantly improving the safety of vehicle driving. Specifically, the first bracket adopts an arc-shaped end cap and a hollow square tubular connecting rod. The arc design can effectively disperse the side impact force, avoid stress concentration, and enhance the impact resistance. The hollow square tubular structure has good compressive and torsional resistance, and is firmly connected to the end cap by welding, improving the overall stability. Furthermore, the connecting plate of the second bracket adopts a differentiated plate thickness design, combined with the integrated reinforcing rib and transition section design, which can reasonably distribute the strength, prevent stress concentration, and enhance the rigidity and strength of the connecting plate. Moreover, the protective plate of the second bracket is arranged around the outer contour of the connecting plate and vertically, forming a comprehensive three-dimensional protection system together with the crisscrossing reinforcing ribs, which can effectively protect the side of the vehicle. Furthermore, this application also includes a third bracket that is threadedly connected to a pre-set mounting point on the vehicle via multiple bolts. The entire blood collection and installation operation is convenient, and it is easy to disassemble and replace a single component without having to disassemble the entire structure on a large scale, which improves maintenance efficiency and reduces maintenance difficulty and cost.
