Description

Technical Field

[0001] This invention relates to the field of lightweight truck bumper structure technology, and more specifically to a lightweight truck bumper structure and its application method. Background Technology

[0002] The bumper structure is an essential component of the overall body of a lightweight truck. The main function of a lightweight truck is to absorb and mitigate external impacts and to protect the front and rear of the truck body. Therefore, to achieve the above technical effects, the conventional bumper structure consists of three main parts: the outer panel, the buffer material, and the crossbeam. The outer panel and the buffer material are made of plastic, and the crossbeam is made of cold-rolled sheet with a thickness of about 1.5 mm, which is stamped into a U-shaped channel. This gives the conventional lightweight bumper a certain buffering effect. At the same time, the conventional outer panel and the buffer material are attached to the crossbeam, and the crossbeam is connected to the longitudinal beam of the frame with bolts, so it is easy to disassemble at any time during use.

[0003] The outer panel mainly consists of the front bumper body, fog light cover, and mesh panel. The bumper body, fog light cover, and mesh panel are fixedly connected by a snap-fit ​​mechanism or bolts. However, this conventional outer panel structure still has the following problems during use.

[0004] 1. Poor filtration effect of the mesh plate. The main reason for this problem is that the conventional mesh plate is mainly used for heat dissipation and to remove larger impurities. However, during use, due to the large diameter of the filter holes in the mesh plate, broken leaves and small insects can be sent into the vehicle body by the airflow generated by the movement of a light truck. This may cause impurities in the vehicle's air conditioning pipes, which will affect the overall performance of the air conditioning system and may even cause damage in severe cases, resulting in economic losses.

[0005] Second, the mesh panels have poor impact protection. The main reason for this problem is that conventional mesh panels are mainly made of plastic materials. Therefore, when a conventional mesh panel is involved in an impact accident, the impact force will cause the mesh panel to break and fracture. As a result, the fragments generated during the impact will enter the vehicle body under the action of external force, causing damage to the internal parts of the vehicle and resulting in certain economic losses. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a lightweight truck bumper structure and its application method to solve the problems existing in the background art.

[0008] In a preferred embodiment, the fixing grooves on the outer walls of the first limiting plate and the second limiting plate are engaged with the outer wall of the fixing plate at one end of the bolt device.

[0009] In a preferred embodiment, a slotted plate is threadedly connected to the outer wall of the other end of the bolt device, and a nut is threadedly connected to the outer wall of the other end of the bolt device. A storage compartment is formed on the inner wall of one side of the slotted plate. The nut is inclined near the inner wall of the storage compartment. A slotted outer plate is fixedly connected to the inner wall of the slotted plate. A filter screen is fixedly connected to the inner wall of the slotted outer plate. The diameter of the mesh holes on the surface of the filter screen is 0.1 mm. A hollow plate is fixedly connected to the inner wall of the other side of the slotted plate. A sleeved outer compartment is fixedly connected to the inner wall of the hollow plate. A buffer central compartment is sleeved on the outer wall of the sleeved outer compartment. A spring is fixedly connected to the inner wall of the sleeved outer compartment. A buffer outer compartment is fixedly connected to one end of the sleeved outer compartment. A mesh outer plate is fixedly connected to one end of the buffer outer compartment.

[0010] In a preferred embodiment, an airflow steel plate is fixedly connected to the inner wall of the outer mesh plate, and an airflow hole is provided on the inner wall of the airflow steel plate. The airflow hole is shaped like a frustum. Miniature rotating rods are sleeved on the inner walls of both sides of the hollow plate, and a connecting rod is fixedly connected to the outer wall of the middle part of the miniature rotating rod.

[0011] In a preferred embodiment, a gripper plate is fixedly connected to the outer wall of the connecting rod, a slot is provided on the inner wall of one side of the gripper plate, a sleeve rod is fixedly connected to the slot on one side of the gripper plate, a transmission plate is fixedly connected to one side of the sleeve rod, a buffer outer chamber is fixedly connected to one end of the transmission plate, and a protective layer is fixedly connected to the outer wall of the buffer outer chamber.

[0012] In a preferred embodiment, a buffer chamber is fixedly connected to the outer wall of the other side of the gripper plate, the transmission plate is a sleeve structure, and a spring is fixedly connected to the inner wall of the transmission plate.

[0013] The technical effects and advantages of this invention are as follows:

[0014] 1. The present invention, by incorporating a filter screen, facilitates the removal of airborne impurities and some airborne insects by the airflow. After being screened by the mesh plate, these impurities are further blocked by the outer wall of the filter screen, thereby preventing them from entering the vehicle air conditioning system and thus avoiding economic losses.

[0015] 2. This invention, by incorporating a mesh plate, filter screen, airflow holes, outer screen plate, and connecting support plate, facilitates airflow during vehicle operation. The airflow passes through the mesh plate and filter screen, entering the airflow holes. Simultaneously, under the influence of air pressure, the airflow plate and outer screen plate press against the connecting support plate. This pressing force causes the buffer outer compartment to move inwards towards the hollow plate, which in turn causes the connecting outer compartment to move inwards towards the buffer core compartment. This compresses the spring inside the connecting outer compartment. Therefore, when the lightweight truck brakes, the inertia of the vehicle body, combined with the elasticity of the spring inside the buffer core compartment, causes the outer screen plate to move forward. Simultaneously, the back-and-forth cushioning action of the spring causes the filter screen to oscillate, removing impurities from its surface through this oscillation force. This prevents clogging of the filter screen and avoids reduced efficiency of the vehicle's onboard system. Attached Figure Description

A spring 223 is fixedly connected to the inner wall of the transmission plate 222.

[0029] In this embodiment, the working principle of this part of the embodiment is as follows: When the vehicle is in use, impurities and insects in the air are filtered by the mesh plate 201 and sent to the outer wall of the filter screen 208 under the action of the airflow, thereby preventing impurities from entering the vehicle air conditioning system and causing certain economic losses. At the same time, when the vehicle is driving, the airflow generated will pass through the mesh plate 201 and the filter screen 208 and enter the airflow hole 213. Under the action of air pressure flow, the airflow steel plate 211 and the outer screen plate 207 will squeeze the connecting support plate 212. At the same time, the force generated by the squeezing will cause the buffer outer compartment 214 to move into the hollow plate 220, which will then cause the sleeve outer compartment 219 to move into the buffer central compartment 218, thereby causing the sleeve outer compartment 219 to move into the inner wall of the buffer central compartment 218. Spring 223 is in a compressed state. Therefore, when the lightweight truck is braking, the inertia generated by the vehicle body will cause the outer mesh plate 207 to move forward under the elastic action of spring 223 inside the buffer center compartment 218. At the same time, under the back-and-forth buffering action of spring 223, the filter mesh 208 is in a certain swinging state, so that impurities on the surface of the filter mesh 208 can be removed by the swinging force. Some of the removed impurities will pass through the mesh plate 201 and leave the vehicle body under the action of inertia, while others will slide into the storage compartment 209 for storage under the action of the inclined inner wall of the slot plate 203. At the same time, the airflow generated by the vehicle will cause the buffer outer compartment 214 to squeeze the outer compartment 219, and at the same time, it will drive the gripper plate 215 to adjust the angle accordingly through the transmission plate 222. This causes the spring 223 inside the buffer chamber 221 to be continuously compressed. At the same time, when the vehicle is in the moment of impact, the impact force and fragments generated will penetrate the mesh plate 201 and nut 205 until they come into contact with the airflow steel plate 211, which is in an interception state. Meanwhile, the spring 223 inside the buffer chamber 221, which is in a compressed state, will act as an elastic support for the airflow steel plate 211, thereby increasing its overall compressive deformation resistance, so as to assist in the interception of fragments and prevent the airflow steel plate 211 from deforming due to uneven force in the middle.

[0030] Working principle of the invention:

[0031] Step 1: When the vehicle is in use, impurities and insects in the air will be filtered by the mesh plate 201 under the action of airflow, and then blocked by the outer wall of the filter screen 208. This can prevent impurities from entering the vehicle air conditioning system and thus preventing economic losses.

[0032] Step Two: Simultaneously, during vehicle operation, the airflow generated passes through the mesh plate 201 and filter screen 208, entering the airflow hole 213. Under the influence of air pressure, the airflow steel plate 211 and the outer mesh plate 207 compress the buffer outer chamber 214. This compression force causes the buffer outer chamber 214 to move towards the interior of the hollow plate 220, which in turn causes the connecting outer chamber 219 to move towards the interior of the buffer core chamber 218. This compresses the spring 223 inside the connecting outer chamber 219. Therefore, when the lightweight truck brakes, the inertia generated by the vehicle body will compress the spring 223 inside the buffer core chamber 218. With the elasticity of the 3, the outer mesh panel 207 moves forward, and the filter mesh 208 is in a certain swinging state due to the back-and-forth buffering action of the spring 223. This allows the impurities on the surface of the filter mesh 208 to be removed by the swinging force. Some of the removed impurities will pass through the mesh plate 201 and leave the vehicle body due to inertia, while others will slide into the storage compartment 209 for storage and management under the action of the inclined inner wall of the slot plate 203. At the same time, when the airflow generated by the vehicle drives the buffer outer compartment 214 to squeeze the outer compartment 219, it will also drive the gripper plate 215 to adjust the angle accordingly through the transmission plate 222. This causes the spring 223 inside the buffer chamber 221 to be continuously compressed. At the same time, when the vehicle is in the moment of impact, the impact force and fragments generated will penetrate the mesh plate 201 and nut 205 until they come into contact with the airflow steel plate 211, which is in an interception state. Meanwhile, the spring 223 inside the buffer chamber 221, which is in a compressed state, will act as an elastic support for the airflow steel plate 211, thereby increasing its overall compressive deformation resistance, so as to assist in the interception of fragments and prevent the airflow steel plate 211 from deforming due to uneven force in the middle.

3. The application method of a lightweight truck bumper structure according to any one of claims 1-2, characterized in that, Includes the following steps: Step 1: When the vehicle is in use, impurities and some insects in the air will be filtered by the mesh plate (201) under the action of airflow, and then blocked by the outer wall of the filter screen (208), thereby preventing impurities from entering the vehicle air conditioning system. Step 2: Simultaneously, during vehicle operation, the generated airflow passes through the mesh plate (201) and filter screen (208), entering the interior of the airflow hole (213). Under the influence of air pressure, the airflow steel plate (211) and the outer mesh plate (207) compress the buffer outer chamber (214). This compression force causes the buffer outer chamber (214) to move towards the interior of the hollow plate (220), which in turn causes its connecting outer chamber (219) to move towards the interior of the buffer center chamber (218). This results in the spring (223) inside the connecting outer chamber (219) being compressed. Therefore, when the lightweight truck is braking, the inertia generated by the vehicle body, combined with the elasticity of the spring (223) inside the buffer center chamber (218), causes the outer mesh plate (207) to move forward. Simultaneously, the back-and-forth buffering action of the spring (223) causes the filter screen (208) to oscillate, allowing it to be oscillated by the oscillating force. Impurities on the surface of the filter screen (208) are removed. Some of the removed impurities will pass through the mesh plate (201) and leave the vehicle body due to inertia. Others will slide into the storage compartment (209) for storage and management under the action of the inclined surface of the inner wall of the slot plate (203). At the same time, the airflow generated by the vehicle drives the buffer outer compartment (214) to squeeze the outer compartment (219). Simultaneously, the transmission plate (222) drives the grab plate (215) to adjust the angle accordingly, thereby driving the spring (223) inside the buffer compartment (221) to continuously compress. At the same time, when the vehicle is in the moment of impact, the impact force and fragments generated will penetrate the mesh plate (201) and nut (205) until they come into contact with the airflow steel plate (211). Meanwhile, the spring (223) in the compressed state inside the buffer compartment (221) will act as an elastic support for the airflow steel plate (211), thereby increasing the overall pressure resistance and deformation performance.
