Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of light trucks, in particular to a multifunctional light truck body capable of reducing wind resistance. BACKGROUND

[0002] The intercity freight belongs to a professional logistics distribution service, and only focuses on providing short-distance logistics distribution between A and B in a city, and usually meets two different needs of "multiple products, single party receiving" or "single product, multiple parties receiving". The distributed goods are mainly large in quantity and volume, and the city light truck is generally used for distribution during the distribution process. Since the light truck chassis is high, the lower side structure is exposed, and the lower side airflow is easy to form turbulence during driving, and the large wind resistance of the vehicle itself works together to greatly increase the vehicle wind resistance and fuel consumption.

[0003] As one of the air dynamics components, the side skirt refers to the skirt plate installed on both sides of the vehicle body, which is used to reduce the airflow entering the bottom of the vehicle body, has a certain spoiler effect, and can obviously reduce the air resistance under certain conditions. The side skirt plate, as one of the air dynamics components of the truck, has a similar effect to the flow guide cover, and has the functions of reducing wind resistance and fuel consumption. However, since the small light truck for city distribution needs to install up and down ladders on both sides to facilitate climbing and unloading, a guardrail structure is generally used to protect and climb, so the side skirt cannot be installed. Therefore, a device is needed that can reduce wind resistance during use without affecting the climbing operation. SUMMARY

[0004] The present application aims to provide a multifunctional light truck body capable of reducing wind resistance to solve the problems in the background art.

[0005] In order to solve the above technical problems, the present application provides the following technical scheme: a multifunctional light truck body capable of reducing wind resistance, comprising a vehicle body, a connecting plate fixedly connected to the lower side of the vehicle body, a side skirt plate fixedly connected to the side of the connecting plate away from the vehicle body, a side wall of the side skirt plate being attached to the outer wall of the vehicle body, at least one stepping hole being formed in the side skirt plate, the stepping hole forming a stepping position for the climber, and a plugging mechanism being provided on one side of the side skirt plate, the plugging mechanism being capable of plugging the stepping hole when the vehicle is driving.

[0006] According to the technical scheme, the blocking mechanism comprises a fixed strip fixedly connected to one side wall of the side apron close to the vehicle body, a slide plate slidably arranged on the fixed strip, at least one wind blocking plate hingedly connected to the slide plate through a torsion spring, a strip gear arranged on one side wall of the slide plate, a gear wheel meshed with the strip gear, a threaded rod rotatably arranged in the gear wheel, two connecting blocks fixedly arranged on the side apron and sleeved with two ends of the threaded rod, the threaded rod being rotatable between the two connecting blocks, and at least one set of blocking units arranged on the threaded rod and vertically movable to block the stepping hole.

[0007] According to the technical scheme, the blocking unit comprises a sliding groove fixedly connected to the side apron, the sliding groove being vertically arranged, a sliding block slidably arranged in the sliding groove, a plug rod fixedly connected to the sliding block, a connecting frame fixedly connected to one side of the plug rod, the connecting frame being threadedly connected to one side of the threaded rod, a U-shaped connecting rod sleeved with the plug rod, the U-shaped connecting rod being slidable on the plug rod, and an blocking block fixedly connected to one end of the U-shaped connecting rod and capable of blocking the stepping hole.

[0008] According to the technical scheme, the upper surface of the stepping hole is obliquely arranged, the area of the side of the stepping hole close to the vehicle body is greater than the area of the side of the stepping hole away from the vehicle body, and the top of the blocking block is provided with a slope structure matched with the stepping hole.

[0009] According to the technical scheme, the bottom of the blocking block is provided with a moving groove, a first magnet movably arranged in the moving groove, a spring fixedly connected between the first magnet and the top wall of the moving groove, a fixed groove arranged in the bottom of the stepping hole, and a second magnet fixedly connected in the fixed groove, the upper surface of the second magnet being located in the same plane as the lower surface of the inner wall of the stepping hole.

[0010] According to the technical scheme, the magnetic pole of the first magnet close to the second magnet is opposite to the magnetic pole of the second magnet close to the first magnet, and the force required for the first magnet and the second magnet to separate after being in contact is greater than the force required for the spring to deform.

[0011] According to the technical scheme, a clock spring is arranged between the threaded rod and the connecting block, and the force required for the torsion spring to deform is greater than the force required for the clock spring to deform.

[0012] According to the technical scheme, a mounting groove is arranged on the connecting plate, a bolt hole is arranged on the vehicle body at the mounting groove, a bolt penetrates through the mounting groove, and the bolt is threadedly matched with the bolt hole.

[0013] According to the above technical solution, a warning mechanism is also provided in the vehicle body. The warning mechanism includes an air hole with an L-shaped structure. One end of the air hole is connected to the upper side of the bolt hole, and the other end of the air hole passes through the front side of the vehicle body and is connected to the outside. A shock absorber is fixedly connected to the inner wall of the air hole. A circular hole with a front-to-back through hole is opened in the middle of the shock absorber. A whistle is fixedly connected to the inner wall of the circular hole.

[0014] According to the above technical solution, the side skirt is provided with multiple reinforcing ribs on the side near the middle of the vehicle body.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0016] By incorporating a vehicle body, connecting plates, side skirts, and foot holes on the side skirts, operators can easily access the vehicle from the side. A sealing mechanism is also included, where airflow causes the sliding plate to slide as the vehicle moves, thereby blocking the foot holes and creating a complete seal on the underside of the vehicle, reducing wind resistance.

[0017] By incorporating a first magnet, a spring, and a second magnet, the device allows the sealing block to move upward relative to the foot hole when the vehicle is stopped. The collision between the first magnet and the sealing block shakes off sewage and other contaminants that have adhered to the surface of the sealing block during operation, thus achieving self-cleaning of the sealing block. This prevents the accumulation of contaminants over a long period, which could affect the sealing of the foot hole. It also prevents operators from contaminating their shoes when stepping on the foot hole.

[0018] By setting up a warning mechanism, an alarm can be triggered when the side skirts are removed without authorization or when the side skirts detach due to excessive wind resistance during driving, thus serving as a warning and preventing uneven force distribution on both sides of the vehicle, thereby reducing safety hazards.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-7 The present invention provides a technical solution: a multi-functional light truck body with reduced wind resistance, including a vehicle body 1, a connecting plate 2 fixedly connected to the lower side of the outer wall of the vehicle body 1, an installation groove 3 opened on the connecting plate 2, a bolt hole opened on the lower side of the vehicle body 1 above the installation groove 3, a side skirt 4 fixedly connected to the outer wall of the connecting plate 2, the upper side of the outer wall of the side skirt 4 in contact with the outer wall of the vehicle body 1, a step hole 6 opened on the side skirt 4, a number of reinforcing ribs 5 fixedly connected to the side of the outer wall of the side skirt 4 near the middle of the vehicle body 1, and a sealing mechanism 7 also provided on the side of the side skirt 4 where the reinforcing ribs 5 are provided;

[0030] When in use, bolts, anti-slip plates, etc. are first threaded through the mounting groove 3 and the inner wall of the bolt hole to fix the connecting plate 2, the vehicle body 1, and the side skirt 4. During driving, the side skirt 4 will block the airflow on both sides of the vehicle body 1, reducing the resistance encountered by the vehicle body 1 during movement.

[0031] The blocking mechanism 7 includes a fixing strip 701. One side of the outer wall of the fixing strip 701 is fixedly connected to the outer wall of the side skirt 4. A sliding plate 702 is slidably connected to the other side of the outer wall of the fixing strip 701. A wind baffle 703 is hinged to the outer wall of the sliding plate 702 via a torsion spring. The outer wall of the sliding plate 702 is provided with a toothed structure. A gear 704 meshes with the rear outer wall of the sliding plate 702. A threaded rod 705 is fixedly connected to the inner wall of the gear 704. A connecting block 706 is rotatably connected to the lower part of the outer wall of the threaded rod 705 via a spring. The force required for the torsion spring at the connection between the outer wall of plate 703 and the outer wall of slide plate 702 is greater than the force required for the spring at the connection between threaded rod 705 and connecting block 706. This can prevent the slide plate 702 from not moving when the wind baffle plate 703 is folded into a flat surface by the wind, thus preventing the sealing unit from sealing the foot hole 6. The threaded rod 705 can rotate between the two connecting blocks 706. The threaded rod 705 is provided with at least one set of sealing units. The sealing units can move vertically following the rotation of the threaded rod 705 and seal the foot hole 6.

[0032] The sealing unit includes a groove 707 fixedly connected to the outer wall of the connecting block 706. The outer wall of the groove 707 is fixedly connected to the outer wall of the side skirt 4. The groove 707 is open on the side facing the middle of the vehicle body 1. A slider 708 is slidably connected to the inner wall of the groove 707. An insert rod 709 is fixedly connected to the outer wall of the slider 708. The insert rod 709 extends to the outside of the groove 707 on the side closer to the vehicle body 1. A connecting bracket 710 is fixedly connected to the outer wall of the insert rod 709. One side of the connecting bracket 710 is threadedly connected to the outer wall of the threaded rod 705. A U-shaped connecting rod 711 is sleeved on the outer wall of the insert rod 709. The outer wall of the insert rod 709 is slidably connected to the inner wall of the U-shaped connecting rod 711. One end of the U-shaped connecting rod 711 is fixedly connected to... A sealing block 712 is located on the upper side of the foot pedal hole 6. The upper surface of the foot pedal hole 6 is inclined and descends from the side closer to the middle of the vehicle body 1 to the side farther away from the vehicle body 1. The upper surface of the sealing block 712 has a ramp structure on the side closer to the side skirt 4, and the side of the sealing block 712 closer to the side skirt 4 is located on the upper inner side of the foot pedal hole 6. Tracks for the sealing block 712 to slide can be provided on the inner walls on both sides of the foot pedal hole 6, so that the sealing block 712 can block the foot pedal hole 6. At the same time, when the sealing block 712 is away from the foot pedal hole 6, the track provides a force point, increases the connection point of the sealing block 712, thereby reducing the pressure of the U-shaped connecting rod 711 supporting the sealing block 712 and extending the service life of the U-shaped connecting rod 711.

[0033] During the movement of the vehicle body 1, a large amount of airflow passes through the lower side. The airflow pushes the wind deflector 703, causing the slide plate 702 to slide on the fixed strip 701. Due to the meshing relationship between the slide plate 702 and the gear 704, the gear 704 rotates. In turn, the gear 704 rotates and drives the threaded rod 705 to rotate. At the same time, the spring at the connection between the connecting block 706 and the threaded rod 705 is tightened. When the threaded rod 705 rotates, since the outer wall of the threaded rod 705 is threadedly connected to the inner wall of the connecting frame 710, the rotation of the threaded rod 705 is converted into the linear motion of the connecting frame 710. The connecting frame 710 will drive the insert rod 709 and the slider 708 to descend. At the same time as the insert rod 709 descends, it will drive the U-shaped connecting rod 711 and the sealing block 712 to descend. After the sealing block 712 descends, it will seal the foot hole 6, thereby making the side skirt 4 completely covered and reducing the resistance of the vehicle body 1.

[0034] After parking, the spring force at the connection between the threaded rod 705 and the connecting block 706 will cause the threaded rod 705 to rotate, which will cause the gear 704 to rotate. In turn, the gear 704 will push the slide plate 702 to reset. During the rotation of the threaded rod 705, the insert rod 709 will move upward, which will cause the U-shaped connecting rod 711 and the sealing block 712 to move upward, thereby causing the sealing block 712 to leave the inside of the foot hole 6, so that the foot hole 6 on the side skirt 4 becomes the footing position for the operator to climb, thus facilitating use.

[0035] The lower surface of the sealing block 712 is provided with a moving groove. A spring 714 is fixedly connected to the upper side of the inner wall of the moving groove. A first magnet 713 is fixedly connected to the lower end of the spring 714. The outer wall of the first magnet 713 is slidably connected to the inner wall of the moving groove. The lower surface of the foot hole 6 is provided with a fixing groove. A second magnet 715 is fixedly connected to the inner wall of the fixing groove. The upper surface of the second magnet 715 is on the same plane as the lower surface of the inner wall of the foot hole 6. A warning mechanism 716 is provided inside the vehicle body 1 above the bolt hole. The lower side of the first magnet 713 and the upper side of the second magnet 715 are opposite magnetic poles. The force required for the first magnet 713 to separate after contact with the second magnet 715 is greater than the force required for the spring 714 to deform.

[0036] After the sealing block 712 descends, the first magnet 713 and the second magnet 715 approach each other, causing them to attract each other and firmly embed the sealing block 712 inside the footrest hole 6, forming a solid seal on the opposite side skirt 4. When the sealing block 712 resets, the U-shaped connecting rod 711 moves upward, causing the sealing block 712 to move upward as well. At this time, the first magnet 713 and the second magnet 715 attract each other, causing the first magnet 713 to move downward relative to the sealing block 712, stretching the spring 714. As the sealing block 712 moves upward, it gradually moves closer to the vehicle body 1. When the part moves to one side, the first magnet 713 will slide on the surface of the sealing block 712 toward the middle of the vehicle body 1. Eventually, the first magnet 713 will detach from the surface of the second magnet 715. Under the pull of the spring 714, the first magnet 713 will quickly slide into the interior of the sealing block 712, impacting the spring 714 and the sealing block 712. This will shake off the dirt that adheres to the outer wall of the sealing block 712 during the journey, achieving self-cleaning of the sealing block 712. This will prevent the accumulation of pollutants over a long period of time, which would affect the sealing of the foot hole 6 by the sealing block 712. At the same time, it can prevent the operator from contaminating the surface of their shoes when stepping on the foot hole 6.

[0037] The warning mechanism 716 includes an air hole 601, which has an L-shaped structure. One end of the air hole 601 is connected to the upper side of the bolt hole, and the other end of the air hole 601 is connected to the front side of the vehicle body 1. A shock absorber 602 is fixedly connected to the inner wall of the air hole 601. A circular hole that runs through the front and rear is opened in the middle of the shock absorber 602. A whistle 603 is fixedly connected to the inner wall of the circular hole in the middle of the shock absorber 602.

[0038] When repairing a vehicle, the side skirt 4 can be removed simply by removing the bolts that secure the vehicle body 1 and the connecting plate 2. If the side skirt 4 is removed without authorization or the bolts connecting the connecting plate 2 and the vehicle body 1 come loose during driving, the airflow at the front of the vehicle body 1 will be discharged through the whistle 603 and the air hole 601 from the bottom of the bolt hole, thereby causing the whistle 603 to make a sound to warn the driver and passengers.
