[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0025] Referring to 1-4, one embodiment of this utility model provides a reinforced side guardrail assembly for trucks, including a mounting plate 1, which provides a stable mounting and support platform for components such as a placement frame 3 and a sliding plate 5, ensuring that the entire guardrail structure can be firmly fixed to the truck. A placement frame 3 is provided on one side of the top center of the mounting plate 1, providing a stable placement platform for the sliding plate 5. Fixing plates 4 are fixedly connected to the left and right sides of the top of the placement frame 3. The sliding plate 5 is provided inside the fixing plate 4, providing support for the sliding plate 5. A limiting hole 11 further limits the sliding plate 5, preventing it from shifting or falling off during sliding. A buffer plate 2 is provided on the top of each sliding plate 5, which directly bears the impact force upon impact and transmits the force to the buffer spring 15 and elastic pad 20 below, thus providing cushioning. The function is as follows: two second sliding grooves 13 are opened on the inner side of the fixed plate 4, which are used to cooperate with the sliders 12 on both sides of the sliding plate 5 to slide inside, so that the sliding plate 5 can slide smoothly left and right on the fixed plate 4, realizing the position adjustment of the guardrail in the width direction to adapt to the truck body of different sizes. The sliders 12 are slidably connected in the middle of the second sliding grooves 13, and are used to slide inside the second sliding grooves 13. The sliders 12 are fixedly connected to the sliding plate 5. The bottom inner side of the sliding plate 5 is fixedly connected with evenly distributed buffer springs 15. When the buffer plate 2 is impacted and pressed down to the pressure plate 16, the buffer springs 15 are compressed. The elastic potential energy of the spring is used to absorb and store the impact energy, thereby effectively reducing the impact force on the truck body and cargo, and restoring the buffer plate 2 to its initial position after the impact.

[0026] The mounting plate 1 has a first sliding groove 6 in the middle, providing guiding space for the sliding of the placement frame 3 on the mounting plate 1. This allows the placement frame 3 to drive the components above it to slide longitudinally on the mounting plate 1, realizing the adjustment of the guardrail's position in the length direction. The first sliding groove 6 is slidably connected to the placement frame 3 in the middle. Both the mounting plate 1 and the placement frame 3 have evenly distributed positioning holes 9 in the middle. These holes, in conjunction with fixing bolts 8, fix the sliding position of the placement frame 3 on the mounting plate 1, ensuring the guardrail remains stable and does not shift after being adjusted to the appropriate length. The sliding plate 5 and the fixing plate 4, as well as both sides of the placement frame 3, have evenly distributed limiting holes 11 in the middle. These holes, in conjunction with adjusting bolts 10, limit the sliding position of the sliding plate 5 on the fixing plate 4, preventing the sliding plate 5 from sliding off the fixing plate 4 under external force. The position of the sliding plate 5 can be adjusted as needed to accommodate different width protection requirements. Each positioning hole 9 is threaded with a fixing bolt 8 to fix the placement frame 3 to a designated position on the mounting plate 1. Each limiting hole 11 is threaded with a fixing bolt 8 in the middle. The sliding plate 5 is fixedly connected to the fixed plate 4 by adjusting bolts 10. L-shaped plates 18 are fixedly connected to both the front and rear sides of the sliding plate 5 to provide sliding guidance for the support plate 19. Support plates 19 are slidably connected to the middle of each L-shaped plate 18 for sliding within the L-shaped plates 18 of the sliding plate 5. The support plates 19 are fixedly connected to the buffer plate 2. Insert plates 14 are fixedly connected to one side of the sliding plate 5, cooperating with insert blocks 7 to fix the position of the support plates 19 and prevent them from sliding. The top of the buffer springs 15 are... A pressure plate 16 is fixedly connected to the buffer plate 2, which evenly transmits the elastic force of the buffer spring 15 to the buffer plate 2, and plays a role in positioning and protecting the buffer spring 15. Insert blocks 7 are slidably connected in the middle of the insert plate 14, which can be pulled out from the insert plate 14, so as to easily remove the buffer plate 2 from the sliding plate 5 for maintenance or replacement of the buffer plate 2. Pull blocks 17 are fixedly connected to one side of the insert block 7, which makes it easy for the operator to pull the insert block 7. Elastic pads 20 are provided on the top of the buffer plate 2 to reduce the direct impact of the impact force on the buffer plate 2.

[0027] Working principle: First, fix the mounting plate 1 to a suitable position on the side wall of the truck body. Place the placement rack 3 on the first slide groove 6 of the mounting plate 1. According to the height requirements of the truck, slide the placement rack 3 to a suitable position. Insert the fixing bolt 8 through the positioning hole 9 to fix the placement rack 3 on the mounting plate 1, completing the installation and positioning of the placement rack 3. Slide the sliding plate 5 inside the fixing plate 4 through the cooperation of the slider 12 and the second slide groove 13 on the placement rack 3. Then, adjust the position of the sliding plate 5 according to the side length of the truck. After adjusting to a suitable position, fix the sliding plate 5 with the adjusting bolt 10. Then adjust the position of the guardrail in the width direction. Slide the support plate 19 at the bottom of the buffer plate 2 and the L-shaped plate 18 inside the sliding plate 5. Then insert the insert 7 into the insert plate 14 on one side of the sliding plate 5 to adjust the sliding position of the support plate 19. Once the buffer plate 2 is fixed in place to prevent it from sliding, the installation of the truck guardrail is complete. When the side of the truck is impacted, the buffer plate 2 first contacts the impacting object, and the elastic pad 20 initially acts as a buffer, reducing the direct impact of the impact on the buffer plate 2. As the impact continues, the buffer plate 2 slides downward, simultaneously moving the support plate 19 downward, causing the support plate 19 to press down on the pressure plate 16. The pressure plate 16 then compresses the buffer spring 15 downward. The buffer spring 15 uses its own elasticity to convert some of the impact energy into elastic potential energy for storage, thereby effectively reducing the transmission of the impact force to the truck compartment and playing a buffering and shock-absorbing role. If the buffer plate 2 is damaged and needs repair or replacement, first pull the pull block 17 to pull the insert block 7 out of the insert plate 14 of the sliding plate 5, and then remove the support plate 19 at the bottom of the buffer plate 2 from the L-shaped plate 18 inside the sliding plate 5 for repair or replacement.
