[0032] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0033] An embodiment of the present application provides a front lower protection assembly for a commercial vehicle, which can solve the problem in the related art that the front lower protection beam of the commercial vehicle is relatively high, which is inconvenient to step on and causes inconvenience in cleaning the front of the vehicle.

When the foldable front step 2 is in the unfolded state, the foldable front step 2 protrudes from the side wall of the front lower protection beam 1.

[0035] In actual use, the main function of the front lower protection assembly is to provide a convenient stepping function for getting on and off the vehicle while ensuring the strength of the front structure of the vehicle, and can be folded and stowed when not needed to optimize the external contour of the vehicle and reduce wind resistance and potential collision risks during driving. The front lower protection beam 1 is the main load-bearing structure of the assembly, responsible for supporting the entire protection assembly and ensuring its stability and safety during vehicle driving. The foldable front step 2 is set below the top surface of the front lower protection beam 1 and can be connected to the front lower protection beam 1 by rotating in the horizontal direction to achieve the unfolding or folding function. When in the unfolded state, the foldable front step 2 protrudes from the side wall of the front lower protection beam 1, which is convenient for the operator to step on, and can provide the operator with a stepping platform with suitable height and stability, so that the operator can stand on it to clean the front part of the commercial vehicle, and the foldable front step 2 is connected to the front lower protection beam 1 by rotating in the horizontal direction, which will not occupy the Z-direction space of the car, and will not affect the spatial position setting of other components, avoiding inconvenience.

[0036] Usually, the operator will stand on the top surface of the front lower protective beam 1 to clean the vehicle in front, but due to the high height of the front lower protective beam 1, it is not convenient for the operator to stand on the top surface of the front lower protective beam 1, while the foldable front step 2 can protrude from the side wall of the front lower protective beam 1, and the foldable front step 2 is lower than the top surface of the front lower protective beam 1, which brings convenience for the operator to step on, and it is convenient for the operator to stand on the foldable front step 2 to clean the vehicle in front.

[0037] In some optional embodiments, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, Figure 4 and Figure 5 The figure shows a situation where the front lower protection assembly is connected and fixed to the vehicle body 8, wherein the front lower protection assembly includes a front lower protection beam 1; a foldable front step 2, wherein the foldable front step 2 is arranged below the top surface of the front lower protection beam 1, and the foldable front step 2 is connected to the front lower protection beam 1 by being rotated in the horizontal direction, so as to enable the foldable front step 2 to be unfolded or folded; when the foldable front step 2 is in the unfolded state, the foldable front step 2 protrudes from the side wall of the front lower protection beam 1.

[0038] In actual use, the main function of the front lower protection assembly is to provide a convenient stepping function for getting on and off the vehicle while ensuring the strength of the front structure of the vehicle, and can be folded and stowed when not needed to optimize the external contour of the vehicle and reduce wind resistance and potential collision risks during driving. The front lower protection beam 1 is the main load-bearing structure of the assembly, responsible for supporting the entire protection assembly and ensuring its stability and safety during vehicle driving. The foldable front step 2 is set below the top surface of the front lower protection beam 1 and can be connected to the front lower protection beam 1 by rotating in the horizontal direction to achieve the unfolding or folding function. When in the unfolded state, the foldable front step 2 protrudes from the side wall of the front lower protection beam 1, which is convenient for the operator to step on, and can provide the operator with a stepping platform with suitable height and stability, so that the operator can stand on it to clean the front part of the commercial vehicle, and the foldable front step 2 is connected to the front lower protection beam 1 by rotating in the horizontal direction, which will not occupy the Z-direction space of the car, and will not affect the spatial position setting of other components, avoiding inconvenience.

[0039] An accommodation space for accommodating the foldable front step 2 is provided inside the front lower protective crossbeam 1 along the length direction. The front lower protective crossbeam 1 is the main load-bearing structure of the assembly, responsible for supporting the entire protective assembly and ensuring its stability and safety during vehicle driving. An accommodation space is provided inside the front lower protective crossbeam 1 along the length direction, which is used to store the foldable front step 2 when it is not in use, so as to keep the vehicle appearance neat and tidy and not interfere with the normal layout of the front vehicle of the commercial vehicle. The foldable front step 2 is stored inside the front lower protective crossbeam 1, and when the foldable front step 2 is unfolded, the stability and safety of the foldable front step 2 can be guaranteed.

[0040] In some optional embodiments, such as Figures 1 to 3As shown, the foldable front step 2 includes a step board 21 and a side panel assembly 22 that is rotatably connected to both sides of the step board 21. When the step board 21 is rotated and folded, the two side panel assemblies 22 rotate in the same direction.

When in the unfolded state, the foldable front step 2 protrudes from the side wall of the front lower protective beam 1, providing a convenient standing platform for getting on and off the vehicle. The foldable front step 2 includes a step board 21 and a side panel assembly 22. Both sides of the step board 21 are connected to the front lower protective beam 1 through the side panel assembly 22. When rotating, the two side panel assemblies 22 rotate in the same direction, which can ensure that when the foldable front step 2 is folded, its folding rotation direction is toward one side, and will not occupy too much length space in the front lower protective beam 1.

[0041] In some optional embodiments, such as Figure 6 As shown, the two ends of the side plate assembly 22 are respectively hinged to the step board 21 and the front lower protection beam 1, and the side plate assembly 22 includes a first side plate 221 arranged at the top of the step board 21 and a second side plate 222 arranged at the bottom of the step board 21. The two sides of the step board 21 are connected to the front lower protection beam 1 through the side plate assembly 22, and the two ends of the side plate assembly 22 are respectively hinged to the step board 21 and the front lower protection beam 1, including a first side plate 221 and a second side plate 222, which are respectively located at the top and bottom of the step board 21 to ensure the stable rotation of the step board 21.

[0042] In some optional embodiments, such as Figure 1 , Figure 6 and Figure 7 As shown, a torsion spring 3 or an electric strut 4 is provided at one end of one of the side plate assemblies 22 away from the step plate 21. Figure 1 and Figure 6 A torsion spring 3 is provided at one end of one of the side plate assemblies 22 away from the step board 21, and the torsion spring 3 is installed at one end of one of the side plate assemblies 22 away from the step board 21, and is used to provide assistance when the foldable front step 2 is unfolded or folded, thereby improving the convenience of operation. Figure 7 An electric support rod 4 is provided at one end of one of the side panel assemblies 22 away from the step board 21. The electric support rod 4 is installed at one end of one of the side panel assemblies 22 away from the step board 21, and is used to automatically unfold or fold the foldable front step 2 to improve the operating convenience.

[0043] In some optional embodiments, a limiting member 5 for limiting and fixing the step board 21 is provided at the bottom of the step board 21. The limiting member 5 is provided at the bottom of the step board 21 and is used to fix the foldable front step 2 in the folded state to prevent it from moving.

[0044] In some optional embodiments, such as Figure 6 , Figure 8 and Fig. 9 As shown, Figure 6 , a schematic diagram of two states of the foldable front step 2 when folded or unfolded is shown. Figure 8 and Fig. 9 Schematic diagram of the locking, limiting and unlocking of the foldable front step 2 by the limiting member 5. Figure 8 The limiting member 5 is a spring lock pin, which includes a spring sheet 52 fixed to the front lower protective cross beam 1 and a spring ejector pin 51 clamped to one end of the spring sheet 52. A limiting hole 23 for matching the spring ejector pin 51 is provided on the side plate assembly 22, and the spring sheet 52 is fixed by a self-tapping screw 53. The spring lock pin structure includes a spring sheet 52 and a spring ejector pin 51, and is used in conjunction with the limiting hole 23 on the side plate assembly 22. Figure 6 The schematic diagram of the state of the step plate 21 when folded and unfolded is shown. Figure 8 When the foldable front step 2 needs to be unfolded, the ejector pin 51 is pressed down to make the ejector pin 51 come out of the limiting hole 23 on the side panel assembly 22. Specifically, the limiting hole 23 can be provided on the side panel at the upper end, i.e., the first side panel 221. When the foldable front step 2 needs to be unfolded, the ejector pin 51 is pressed down to make the ejector pin 51 come out of the limiting hole 23 of the first side panel 221, and the foldable front step 2 can be unfolded. After unfolding, the ejector pin 51 will automatically reset under the action of the spring sheet 52. Fig. 9 When the foldable front step 2 needs to be folded, the foldable front step 2 is rotated so that the limiting hole 23 on the first side plate 221 is aligned with the ejection pin 51 and is limited by the ejection pin 51.

[0045] In some optional embodiments, both ends of the front lower protection beam 1 are provided with side step assemblies 6. The side step assemblies 6 are installed at both ends of the front lower protection beam 1 to provide stepping points for passengers to get on and off the vehicle.

The side step assembly 6 includes a first step bracket 61 and a second step bracket 62 spaced apart in the height direction, that is, the side step assembly 6 includes two step brackets. Generally speaking, commercial vehicles usually require three step brackets, two of which are arranged on the vehicle body 8, and an additional one is installed. However, the side step assembly 6 arranged at both ends of the front lower protective beam 1 of the present application includes a first step bracket 61 and a second step bracket 62. In this way, only one step bracket needs to be arranged on the vehicle body 8, which is convenient for reducing the difficulty of assembly design of the vehicle. The second step bracket 62 is detachably connected to the front lower protective beam 1. In actual use, the second step bracket 62 is detachably connected to the front lower protective beam 1, which can adapt to different usage requirements.

[0047] In some optional embodiments, a mounting plate 7 for fixing to the vehicle is provided on the front lower protection cross beam 1. A mounting plate 7 for fixing to the vehicle is also provided on the front lower protection cross beam 1 to ensure that the entire protection assembly is firmly installed.

[0048] The commercial vehicle front lower protection assembly of the present application has the following remarkable effects: compact structure, ingenious design, and a perfect combination of safety protection and convenient boarding and exiting. The design of the foldable front step 2 allows it to be folded and stowed when not in use, optimizing the vehicle's external contour and reducing wind resistance and potential collision risks during driving. The provision of the torsion spring 3 or the electric strut 4 provides assistance when the foldable front step 2 is unfolded or folded, thereby improving operational convenience. The provision of the side step assembly 6 provides additional boarding and exiting step points to accommodate different usage requirements. The design of the mounting plate 7 ensures the secure installation of the entire protection assembly on the vehicle.

[0049] The front lower protection assembly of the present application integrates the first step bracket 61 and the second step bracket 62, and integrates the foldable front step 2. This integrated setting using the front lower protection cross beam 1 ensures the integrity of the overall structure and innovates the design concept of the front lower protection of commercial vehicles, which helps to improve the overall assembly efficiency of the front lower protection, and can help reduce the number of specific components of the vehicle body 8 and reduce the overall difficulty of vehicle production.

[0050] In summary, the commercial vehicle front lower protection assembly of the present application includes a front lower protection beam 1; a foldable front step 2, the foldable front step 2 is arranged below the top surface of the front lower protection beam 1, and the foldable front step 2 is connected to the front lower protection beam 1 by rotation in the horizontal direction, so as to enable the foldable front step 2 to be unfolded or folded. When the foldable front step 2 is in the unfolded state, the foldable front step 2 protrudes from the side wall of the front lower protection beam 1.

[0051] In actual use, the main function of the front lower protection assembly is to provide a convenient stepping function for getting on and off the vehicle while ensuring the strength of the front structure of the vehicle, and can be folded and stowed when not needed to optimize the external contour of the vehicle and reduce wind resistance and potential collision risks during driving.

When in the unfolded state, the foldable front step 2 protrudes from the side wall of the front lower protection beam 1, which is convenient for the operator to step on, and can provide the operator with a stepping platform with suitable height and stability, so that the operator can stand on it to clean the front part of the commercial vehicle, and the foldable front step 2 is connected to the front lower protection beam 1 by rotating in the horizontal direction, which will not occupy the Z-direction space of the car, and will not affect the spatial position setting of other components, avoiding inconvenience.

[0052] The foldable front step 2 includes a step board 21 and a side panel assembly 22 that is rotatably connected to both sides of the step board 21. When the step board 21 is rotated and folded, the two side panel assemblies 22 rotate in the same direction. The foldable front step 2 is set below the top surface of the front lower protective beam 1 and can be connected to the front lower protective beam 1 by rotating in the horizontal direction to achieve an unfolding or folding function. When in the unfolded state, the foldable front step 2 protrudes from the side wall of the front lower protective beam 1, providing a convenient standing platform for getting on and off the vehicle. The foldable front step 2 includes a step board 21 and a side panel assembly 22. Both sides of the step board 21 are connected to the front lower protective beam 1 through the side panel assembly 22. When rotating, the two side panel assemblies 22 rotate in the same direction, which can ensure that when the foldable front step 2 is folded, its folding rotation direction is toward one side, and will not occupy too much length space in the front lower protective beam 1. The two ends of the side plate assembly 22 are respectively hinged to the step board 21 and the front lower protection beam 1, and the side plate assembly 22 includes a first side plate 221 arranged at the top of the step board 21 and a second side plate 222 arranged at the bottom of the step board 21.

[0053] The front lower protection assembly design of the present application not only meets the basic safety requirements for the front lower protection of commercial vehicles, but also greatly improves the practicality and convenience of the vehicle through the integrated and modular design concept.

[0054] 1. Improve assembly efficiency: The present application integrates the front lower protection beam 1, the foldable front step 2 and the side step assembly 6 to form a complete protection assembly module. This integrated design simplifies the assembly process, reduces assembly hours and improves production efficiency. At the same time, due to the standardized interfaces between modules, the error rate and rework rate in the assembly process are also reduced.

[0055] 2. Reduce production difficulty and cost: Through integrated design, the number of body parts is reduced, which not only simplifies the body structure, but also reduces production and procurement costs. In addition, since the integrated module is easy to replace and repair, it also reduces the subsequent maintenance cost of the vehicle.

[0056] 3. Optimize vehicle appearance and performance: The integrated design of the front lower protection assembly makes the vehicle appearance more neat and beautiful. At the same time, due to the ingenious design of the foldable front step 2 and the side step assembly 6, it not only provides a convenient function of getting on and off the vehicle, but also does not affect the driving performance and safety of the vehicle.

[0057] The design of the foldable front step 2 facilitates the optimization of space utilization: the design of the foldable front step 2 makes full use of the space under the front lower protective beam 1, providing a stable stepping platform without taking up additional vehicle space. This design makes the vehicle more efficient in space utilization. Improve operator convenience: the unfolding and folding functions of the foldable front step 2 enable operators to clean and maintain the front part of the commercial vehicle more conveniently. At the same time, due to the moderate height of the step board 21, it also reduces the difficulty and risk of operators getting on and off the vehicle. The use of torsion springs 3 or electric struts 4 provides assistance for the unfolding and folding of the foldable front step 2, making the operation easier and more convenient. This not only improves the efficiency of use, but also reduces the labor intensity of the operator.

[0058] The design of the side step assembly 6 can adapt to different usage requirements: the side step assembly includes a first step bracket 61 and a second step bracket 62 spaced apart in the height direction. This design enables the side step assembly 6 to adapt to passengers of different heights and operating habits. At the same time, the detachable connection of the second step bracket 62 also increases the flexibility of use. Reduce the difficulty of assembly design: by only setting a step bracket on the vehicle body 8 and cooperating with the side step assembly 6 on the front lower protective beam 1, a complete step function can be achieved. This design simplifies the assembly process of the vehicle body 8 and reduces the design difficulty and cost.

[0059] The front lower protection assembly design of the present application cleverly combines the front lower protection cross beam 1, the foldable front step 2 and the side step assembly 6 through the concept of integration and modularization, forming a safe and practical protection assembly module. This design not only improves the assembly efficiency and production performance of the vehicle, but also reduces the production cost and maintenance difficulty. At the same time, the innovative design of the foldable front step 2 and the side step assembly 6 also makes the vehicle more convenient and efficient during use.
