Description

Technical Field

[0001] This utility model relates to the field of logistics vehicle tailgate technology, and in particular to a cargo box tailgate structure for a van-type logistics vehicle. Background Technology

[0002] A van is a commercial vehicle with an independent, enclosed cargo compartment or an integrated cab. It is mainly used for the fully sealed transportation of various goods. Through its fully enclosed cargo compartment structure, the van provides protection against rain, dust, and theft, ensuring the safety and reliability of the goods during transportation. The rear cargo door of the van is a core component installed at the rear of the cargo compartment to seal the cargo loading space. Its core functions are to ensure the safety of the goods, maintain a sealed environment, and improve loading and unloading efficiency.

[0003] Traditional cargo box tailgates, once opened, typically only provide a vertical or inclined unloading ramp, causing goods to easily pile up directly at the tailgate, hindering the unloading of subsequent goods, reducing loading and unloading efficiency and smoothness. Furthermore, traditional tailgates are usually opened or closed all at once, making it inconvenient to open the tailgate as needed.

[0004] Therefore, those skilled in the art have provided a cargo box tailgate structure for van-type logistics vehicles to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a cargo box tailgate structure for a van. A servo motor and a threaded rod work together to drive the main door to move up and down. A support mechanism fixes it as a temporary platform. This platform can serve as a temporary area during loading and unloading to avoid goods piling up at the door. In addition, the segmented door design allows users to choose to open it partially or completely according to their needs, especially when handling large or long items, so as to meet the loading and unloading needs of goods of different sizes.

[0006] To achieve the above objectives, this utility model provides a cargo box tailgate structure for a van-type logistics vehicle, including a box body. A moving mechanism is provided on the other side of the inner wall of the box body. Supporting mechanisms are provided at both ends of the inner wall of the moving mechanism. The moving mechanism includes a main box door. A cavity is opened on the other side of the box body. Slide grooves are opened at both ends on the other side of the cavity. A threaded rod is rotatably connected to the bottom surface of the front slide groove. A threaded sleeve is fitted on the outer wall of the threaded rod. A sliding rod is fixedly connected to the bottom surface of the rear slide groove. A sliding ring is slidably connected to the outer wall of the sliding rod. A sliding block is fixedly connected to one end of the threaded sleeve and the sliding ring near the center of the box body. A connecting block is fixedly connected to one end of each sliding block near the center of the box body. Both connecting blocks are rotatably connected to the upper parts at both ends of the main box door. A servo motor is fixedly connected to the top surface of the front slide groove.

[0007] With the above technical solution, the user first grasps the second handle to pull open the main compartment door, and then rotates the main compartment door until it is parallel to the ground. Then, the servo motor is started by the external controller, which drives the threaded rod to rotate. The threaded sleeve moves accordingly, which in turn drives the sliding block and the main compartment door to move to the bottom of the slide, so that the main compartment door forms a temporary platform. The platform can serve as a temporary area where unloaded goods can be temporarily placed and sorted before being transferred to the final location.

[0008] Furthermore, grooves are provided at both ends on one side of the main box door, and support rods are hinged to the lower ends of the two grooves. Slide plates are slidably connected to the inner walls of the two support rods. Multiple threaded holes are evenly provided on one side of the two support rods and the slide plates. Bolts are provided at the upper ends of the inner walls on one side of the two support rods.

[0009] By using the above technical solution, the support rod is rotated to be perpendicular to the main box door, and then the slide plate is pulled to the required position. The slide plate is then fixed with bolts and threaded holes, providing solid support for the main box door and forming a temporary platform for the main box door, ensuring the stability of the platform and safety when bearing load.

[0010] Furthermore, a right door is provided at the upper part of the rear end of the box, a left door is provided at the upper part of the front end of the box, and a first handle is fixedly connected to the middle of the front end of the other side of the right door.

[0011] The above technical solution adopts a segmented door, which allows users to choose to partially or fully open the door according to their needs. When it is necessary to move larger or longer items, users can choose to fully open the door to obtain more loading space and meet the loading and unloading needs of goods of different sizes.

[0012] Furthermore, a second handle is fixedly connected to the middle of the lower end of the other side of the main compartment door;

[0013] The above technical solution allows operators to open the main compartment door more naturally and effortlessly.

[0014] Furthermore, the output end of the servo motor is fixedly connected to the upper end of the threaded rod;

[0015] The above technical solution reduces transmission delay, allowing the force of the servo motor to be converted into the rotation of the threaded rod more quickly.

[0016] Furthermore, both of the sliding blocks slide on the inner wall of the groove;

[0017] Through the above technical solution, the slide and sliding block form a robust guide structure, which improves the overall rigidity of the tailgate drive system.

[0018] Furthermore, all of the bolts are threadedly connected to the threaded holes;

[0019] The above technical solution uses bolts to generate preload, which compresses the components to be connected, forming a rigid connection that can withstand large tensile loads.

[0020] Furthermore, both connecting blocks slide within the inner wall of the groove;

[0021] Through the above technical solution, the slide provides a clear trajectory for the connecting block, and the connecting block can only slide within the slide, ensuring the straightness and stability of the movement and preventing the main door from shifting, shaking or rotating during the movement.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model proposes a cargo box tailgate structure for a van-type logistics vehicle. Through the cooperation of a servo motor and a threaded rod, the main cargo box door can move up and down, while the support mechanism can stably support it, making it usable as a temporary platform. During loading and unloading, this platform becomes an effective temporary area for temporarily storing goods, thereby avoiding the accumulation of goods at the cargo box door and ensuring the smooth progress of subsequent unloading operations. In addition, this design also adopts a segmented cargo box door, allowing users to choose to partially or fully open the tailgate according to their needs. When it is necessary to move larger or longer items, users can choose to fully open the cargo box door to obtain the maximum loading space and meet the loading and unloading needs of goods of different sizes.

Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides a specific embodiment: a cargo box tailgate structure for a van-type logistics vehicle, including a box body 2, a moving mechanism 1 provided on the other side of the inner wall of the box body 2, and support mechanisms 8 provided at both ends of the inner wall of the moving mechanism 1. The moving mechanism 1 includes a main box door 109, a cavity 3 opened on the other side of the box body 2, and sliding grooves 101 opened at both ends of the other side of the cavity 3. A threaded rod 102 is rotatably connected to the bottom surface of the front sliding groove 101, and a threaded sleeve 1 is fitted on the outer wall of the threaded rod 102. 03, a slide rod 104 is fixedly connected to the bottom surface of the rear slide groove 101, a slide ring 105 is slidably connected to the outer wall of the slide rod 104, a slide block 106 is fixedly connected to one end of the threaded sleeve 103 and the slide ring 105 near the center of the box 2, a connecting block 107 is fixedly connected to one end of the two sliding blocks 106 near the center of the box 2, and the two connecting blocks 107 are rotatably connected to the upper part of both ends of the main box door 109, and a servo motor 108 is fixedly connected to the top surface of the front slide groove 101;

[0035] The user first grasps the second handle 7 to pull open the main compartment door 109, and then rotates the main compartment door 109 until it is parallel to the ground. Then, the user starts the servo motor 108 through the external controller, which drives the threaded rod 102 to rotate. The threaded sleeve 103 moves accordingly, which in turn drives the sliding block 106 and the main compartment door 109 to move to the bottom of the slide 101, so that the main compartment door 109 forms a temporary platform. The platform can serve as a temporary area where unloaded goods can be temporarily placed and sorted before being transferred to the final location.

[0036] Reference Figure 3 , Figure 4 and Figure 5 The main door 109 has grooves 801 at both ends on one side. The lower ends of the two grooves 801 are hinged to support rods 802. The inner walls of the two support rods 802 are slidably connected to slide plates 803. Multiple threaded holes 804 are evenly provided on one side of the two support rods 802 and slide plates 803. Bolts 805 are provided on the upper ends of the inner walls of the two support rods 802. Rotate the support rods 802 to make them perpendicular to the main door 109. Then pull the slide plates 803 to the desired position. Then fix the slide plates 803 with bolts 805 and threaded holes 804, which provides solid support for the main door 109 and makes the main door 109 form a temporary platform, ensuring the stability of the platform and the safety of bearing load. The upper part of the rear end of the box body 2 is provided with a right box door 4, and the upper part of the front end of the box body 2 is provided with a left box door 5. The middle of the front end of the other side of the right box door 4 is fixedly connected to a first handle 6.

[0037] The container adopts a segmented door design, allowing users to choose between partially or fully opening the door as needed. For larger or longer items, fully opening the door provides greater loading space, accommodating loading and unloading requirements for goods of different sizes. A second handle 7 is fixedly connected to the middle of the lower end of the other side of the main door 109, enabling operators to open the main door 109 more naturally and effortlessly. The output end of the servo motor 108 is fixedly connected to the upper end of the threaded rod 102, reducing transmission delay and allowing the force from the servo motor 108 to be converted into the rotation of the threaded rod 102 more quickly. Both sliding blocks 106 are located in the slide groove 101. The sliding inner wall, the slide groove 101 and the sliding block 106 form a robust guide structure, which improves the overall rigidity of the tailgate drive system. Multiple bolts 805 are threadedly connected to the threaded holes 804. By tightening the bolts 805, the bolts 805 generate a preload, which presses the parts that need to be connected together to form a rigid connection that can withstand large tensile loads. Both connecting blocks 107 slide on the inner wall of the slide groove 101. The slide groove 101 provides a clear trajectory for the connecting blocks 107. The connecting blocks 107 can only slide within the slide groove 101, ensuring the linearity and stability of the movement and preventing the main door 109 from deviating, shaking or rotating during the movement.

[0038] Working principle: The user first grasps the second handle 7 to pull open the main compartment door 109, then rotates it until it is parallel to the ground, forming a temporary platform. Next, the user rotates the support rod 802 to make it perpendicular to the main compartment door 109. Then, the user pulls the slide plate 803 to the desired position and secures it using bolts 805 and threaded holes 804. Finally, the user starts the servo motor 108 via an external controller, causing the threaded rod 102 to rotate. The threaded sleeve 103 moves accordingly, which in turn moves the sliding block 106 and the main compartment door 109 to the bottom of the slide groove 101. At this point, the sliding plate 803 contacts the ground, providing solid support for the main door 109 and ensuring the stability of the platform and safety during loading. During loading and unloading, the platform can serve as a temporary area where unloaded goods can be temporarily placed and organized before being transferred to the final location, acting as a buffer and transition. In addition, the design also adopts a segmented door, allowing users to choose to partially or fully open the door according to their needs. When it is necessary to move larger or longer items, users can choose to fully open the door to obtain more loading space and meet the loading and unloading needs of goods of different sizes.
