Description

Technical Field

[0001] This invention belongs to the field of pickup trucks, specifically relating to a protective device for pickup trucks and a pickup truck. Background Technology

[0002] A pickup truck is a cargo vehicle with an open cargo bed and a driver's cab at the front; it can also be used as a passenger vehicle. The cargo bed of a pickup truck can be used to transport various items, such as furniture, building materials, and other goods.

[0003] With the development of technology, pickup trucks have gradually become a common means of transporting goods in people's daily lives. People usually put some goods in the truck bed for transportation. In order to protect the goods from damage, ropes are often used to limit and fix the goods. However, this method does not achieve good operational efficiency and lacks stability. As a result, the goods may collide, which does not achieve a good transportation environment.

[0004] Chinese Patent CN220096239U discloses a steel structure transfer mechanism, including a vehicle body. A protective mechanism is provided on the top of the vehicle body. The protective mechanism includes a protective component and two sets of fixing components. The protective component includes a rubber buffer plate and a protective plate. The rubber buffer plate is located on top of the protective plate. Connecting plates are fixedly installed on both the front and back of the rubber buffer plate. The connecting plates are fixedly connected to the protective plate by bolts. The fixing components include a vertical plate and a side plate. A screw is fixedly installed on the side of the side plate. This utility model, through its designed protective mechanism, facilitates the protection of the vehicle body surface during use, preventing deformation, damage, and wear to the vehicle body after the steel structure is hoisted onto it by a crane. This improves the service life of the vehicle body and enhances the usability of the trackless electric flatbed vehicle.

[0005] However, the protective structure in this patent is fixedly connected to the vehicle body, which can damage the vehicle body and makes it difficult to disassemble the protective structure.

Detailed Implementation

[0036] The following description provides many different embodiments or examples for implementing various features of the invention. The elements and arrangements described in the specific examples below are only for concise expression of the invention and are merely examples, not intended to limit the invention.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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.

[0038] This embodiment provides a protective device for pickup trucks, such as... Figure 1 , Figure 4 , Figure 3As shown, the system includes a protective mechanism 10 and an installation mechanism 20. The installation mechanism 20 includes a connecting frame 21, a positioning plate 22, and a threaded rod 23. The connecting frame 21 is provided with a U-shaped groove 211, and the positioning plate 22 is disposed in the U-shaped groove 211. The threaded rod 23 is threadedly connected to the U-shaped groove 211, and one end of the threaded rod passes through the U-shaped groove 211 and connects to the positioning plate 22. The U-shaped groove 211 of the connecting frame 21 is used to connect to the truck bed frame 40 of the pickup truck, and the positioning plate 22 is used to press and fix the truck bed frame 40 to the connecting frame 21.

[0039] The connecting frame 21 is fixedly connected to the protective mechanism 10, and the protective frame 11 of the protective mechanism 10 can press and release the goods by telescopic movement.

[0040] When a pickup truck needs to be protected while transporting goods, the protective device of the present invention is connected to the pickup truck bed frame 40 through the mounting mechanism 20. The installation position and number of devices on the bed frame 40 can be determined according to the actual usage. When the pickup truck does not need to be protected while transporting goods, the protective device of the present invention can be removed to increase the capacity of the bed frame 40.

[0041] Among them, such as Figure 3 , Figure 2 As shown, the threaded rod 23 is connected to a second handwheel 60, which drives the threaded rod 23 through a turntable, and has the advantages of high adjustment efficiency and labor saving.

[0042] Multiple positioning plates 22 can be installed in the U-shaped groove 211. The multiple positioning plates 22 are preferably evenly distributed along the extension direction of the U-shaped groove 211. This makes the connection between the installation mechanism 20 and the truck bed frame 40 more stable.

[0043] Preferably, the side of the positioning plate 22 that contacts the truck bed frame 40 is provided with anti-slip texture; the anti-slip texture makes the connection between the mounting mechanism 20 and the truck bed frame 40 more stable.

[0044] Preferably, the inner surface of the U-shaped groove is adapted to the outer surface of the edge of the truck bed frame 40 used to connect the connecting frame 21, so that the connection between the connecting frame 21 and the truck bed frame 40 is more stable.

[0045] It should be noted that the present invention does not limit the shape of the connecting bracket 21; preferably, such as Figures 1-3 As shown, the connecting frame 21 is rectangular in shape; this makes it more compatible with the shape of the truck bed frame 40 after connection, while also reducing the use of materials; it also makes it easier to connect the protective mechanism 10 to the connecting frame 21.

[0046] In some embodiments, such as Figure 4As shown, the protective mechanism 10 includes a protective frame 11, a drive rod 12, a turbine 13, a worm gear 14, a drive plate 15, and a support structure 16. The support structure 16 is fixedly connected to the connecting frame 21. The support structure 16 is rotatably connected to the drive rod 12. The end of the drive rod 12 is fixedly connected to the turbine 13, and the middle part is threadedly connected to the drive plate 15. The turbine 13 cooperates with the worm gear 14, and the drive plate 15 is connected to the protective frame 11.

[0047] Preferred, such as Figure 1 , Figure 3 As shown, the support structure 16 is a box structure, and the turbine 13, drive plate 15, and drive rod 12 are all set inside the box structure, which has the advantages of protection and dust prevention.

[0048] In some embodiments, such as Figure 4 As shown, one end of the drive rod 12 is rotatably connected to the support structure 16, and the other end is fixedly connected to the turbine 13. This reduces the amount of material used in the protective mechanism 10 and also reduces the axial length of the protective mechanism 10 on the drive rod 12, thereby reducing the size and weight of the protective device of the present invention and thus reducing the area occupied by the protective device of the present invention on the pickup truck.

[0049] In some embodiments, such as Figure 4 , Figure 5 As shown, the drive plate 15 is connected to the protective frame 11 via a support arm 70, which is slidably connected to the support structure 16. In this way, the support arm 70 supports the protective frame 11, allowing the drive rod 12 to focus solely on its driving function, resulting in high adjustment efficiency and low effort.

[0050] like Figure 5 As shown, the drive plate 15 has a threaded hole, through which the drive plate 15 is connected to the drive rod 12. The outer surface of the drive rod 12 is provided with threads. During the rotation of the drive rod 12, the drive plate 15 is pushed to move through the engagement of the threads.

[0051] In some embodiments, such as Figure 5 As shown, at least two support arms 70 are provided, with at least two support arms 70 located on both sides of the drive rod 12 respectively. This provides greater stability when adjusting the position of the protective frame 11.

[0052] In some embodiments, such as Figure 1 , Figure 6As shown, the protective device is connected to a worm gear drive mechanism 30. A first bevel gear 231 is mounted on the worm 14. The worm gear drive mechanism 30 includes a connecting box 31, a second bevel gear 32, a rotating shaft 33, and a first handwheel 34. The connecting frame 21 is fixedly connected to the connecting box 31. Both the first bevel gear 231 and the second bevel gear 32 are located inside the connecting box 31, and the first bevel gear 231 engages with the second bevel gear 32. The second bevel gear 32 is connected to one end of the rotating shaft 33, and the other end of the rotating shaft 33 is connected to the first handwheel 34. The first handwheel 34 is located outside the connecting box 31. This worm gear drive mechanism 30 has an automatic locking function.

[0053] This embodiment also provides a pickup truck, such as Figure 7 , Figure 8 As shown, the vehicle includes a truck bed frame 40 and the aforementioned protective device, with the protective device connected to both sides of the truck bed frame 40.

[0054] In some embodiments, at least two protective mechanisms 10 are provided on a connecting frame 21, the two protective mechanisms 10 are symmetrically arranged at both ends of the connecting frame 21, and the worm gears 14 of the two protective mechanisms 10 are driven by a worm gear drive mechanism 30. Figure 1 , Figure 3 As shown, the worm gears 14 of the two protective mechanisms 10 can be fixedly connected or integrally formed. This configuration of the protective mechanisms 10 can better limit the cargo within the truck bed frame 40; and the two protective mechanisms 10 are driven by a worm gear drive mechanism 30, which can make the adjustment degree of the two protective mechanisms 10 consistent, so that the force acting on the cargo is more uniform and has a better limiting effect.

[0055] In some embodiments, such as Figure 5 As shown, the protective frame 11 is configured in a grid pattern. This increases the contact area with the goods, avoids force concentration, and provides a better limiting effect.

[0056] In some embodiments, such as Figure 8 , Figure 9 As shown, the ends of both sides of the truck bed frame 40 are provided with operating points.

[0057] In actual operation, when the protective device of the present invention is used, when it is necessary to disassemble the protective device, the second handwheel 60 is turned to drive the threaded rod 23 to rotate. Since the threaded rod 23 and the connecting frame 21 are threadedly connected, the threaded rod drives the positioning plate 22 to move in the U-shaped groove 211, so that the positioning plate 22 can move away from the truck bed frame 40 and no longer play the role of pressing. Then the connecting frame 21 can be lifted up so that the connecting frame 21 can be pulled out from the inside of the positioning seat 50, thus realizing the disassembly of the entire device. Similarly, the entire device can also be installed.

[0058] Next, when it is necessary to protect the materials inside the truck bed frame 40, the first handwheel 34 is turned to rotate the shaft 33. The shaft rotates through the second bevel gear 32 and the first drive transmission rod. Since the drive rod 12 and the drive plate 15 are threadedly connected, the rotation of the transmission rod causes the drive plate 15 to move. The movement of the drive plate 15 causes the protective frame 11 to move closer to the materials, so that the protective frame 11 is in close contact with the materials, thereby enabling the materials to achieve good stability during transportation.
