Abstract

This utility model discloses a wing-opening van structure, which includes a cargo box frame fixed to the van frame, and a top plate, bottom plate, front plate, and rear plate fixed to the cargo box frame. The side plates are divided into a first side plate and a second side plate. The bottom of the first side plate is hinged to the bottom plate, and the top is snapped to the cargo box frame via buckles. The second side plate is located above the first side plate and is mounted on the cargo box frame via a retractable opening and closing mechanism. Traditional wing-opening vans are inconvenient for loading and unloading in narrow spaces, occupy a large space when the door is open, and have poor adaptability. This utility model uses a retractable opening and closing mechanism to control the second side plate, allowing the side plate to be lifted and retracted when the door is opened. Simultaneously, dividing the side plate into upper and lower parts effectively reduces the space required for opening the side plate, solving the problem of difficult loading and unloading in narrow spaces for traditional vehicles, improving cargo loading and unloading efficiency, expanding the vehicle's application scenarios, and enhancing the vehicle's adaptability to different environments.

Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a wing-opening van structure. Background Technology

[0002] In the logistics and transportation sector, wing-opening vans play a vital role in cargo transportation due to their unique opening mechanism, enabling rapid loading and unloading. However, traditional wing-opening vans have several shortcomings.

[0003] Traditional wing-opening vans typically have a one-piece side panel structure. During opening, the entire side panel lifts upwards, requiring a significant amount of space to open the door. In real-world applications, loading and unloading goods often occurs in confined spaces, such as narrow city streets or warehouse aisles. In these space-constrained environments, the large space required for opening the door in traditional wing-opening vans hinders smooth loading and unloading operations. Operators need to spend more time and effort adjusting the vehicle's position to create sufficient opening space, which not only reduces loading and unloading efficiency but also increases operational difficulty and cost.

[0004] Furthermore, traditional wing-opening vans have poor adaptability to various usage scenarios. In situations where space is limited but cargo transportation is still necessary, traditional vehicles cannot meet the requirements, thus restricting their application. Therefore, improving the structure of wing-opening vans to facilitate loading and unloading of goods even in confined spaces, and enhancing the flexibility and adaptability of door opening operations, has become a pressing technical problem to be solved in this field. Utility Model Content

[0005] The purpose of this utility model is to provide a wing-opening van structure to solve the problems of traditional wing-opening vans, such as inconvenient loading and unloading in narrow spaces, large space occupation when opening the door, and poor adaptability.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a wing-opening van structure, the wing-opening van structure comprising:

[0007] The car body frame is fixed to the truck frame;

[0008] The top plate, bottom plate, front plate, and rear plate are all fixed to the car body frame.

[0009] The first side panel is hinged at the bottom to the base plate, and the top of the first side panel is fastened to the car frame by a buckle.

[0010] The second side panel is located above the first side panel and is mounted on the carriage frame via a retractable opening and closing mechanism.

[0011] In one embodiment, the retraction and opening mechanism includes:

[0012] Telescopic rod, the bottom of which is hinged to the frame of the carriage;

[0013] A connecting rod, one end of which is hinged to the car frame, and the middle part of which is hinged to the top of the telescopic rod;

[0014] A first slide groove is disposed on the second side plate;

[0015] A first slider is slidably disposed in the first groove, and the first slider is hinged to the other end of the connecting rod.

[0016] The second slide groove is disposed on the second side plate and is parallel to the first slide groove.

[0017] The second slider is slidably fitted within the second groove and is hinged to the car frame.

[0018] In one embodiment, both the first groove and the second groove are T-shaped grooves.

[0019] In one embodiment, the telescopic rod is a hydraulic piston rod.

[0020] In one embodiment, a traction limiting rope is further included, one end of which is fixed to the carriage frame and the other end of which is connected to the first side plate.

[0021] The above-described technical solutions in the embodiments of this utility model have at least the following technical effects or advantages:

[0022] The wing-opening van structure provided in this embodiment of the utility model divides the side panels into a first side panel and a second side panel. The bottom of the first side panel is hinged to the bottom plate, and the top is fastened to the van frame with buckles. The second side panel is located above the first side panel and is mounted on the van frame via a retractable opening and closing mechanism. This design allows the side panels to be lifted and retracted when the door is opened, overcoming the problem of large space occupation in traditional one-piece side panel opening methods. It effectively reduces the space required for opening the side panels, enabling easy door opening operations in narrow spaces and greatly improving the convenience of loading and unloading goods in confined spaces. Because this utility model solves the problem of inconvenient loading and unloading in narrow spaces, operators no longer need to spend a lot of time and effort adjusting the vehicle position to create sufficient door opening space, thus enabling faster loading and unloading operations, significantly improving loading and unloading efficiency, and reducing logistics and transportation costs.

[0023] This invention improves the adaptability of wing-opening vans to various usage scenarios, making them suitable not only for open spaces but also for use in confined environments such as narrow city streets and warehouse passageways. This expands the vehicle's usage scenarios, increases its market competitiveness, and meets the cargo transportation needs of different users in different scenarios. Attached Figure Description

[0035] Please see Figures 1 to 4This application provides a wing-opening van structure, including a van frame 1, a top plate, a bottom plate, front and rear plates 6, a first side plate 2, and a second side plate 3. The van frame 1 is fixed to the van chassis. The top plate, bottom plate, front and rear plates 6 are all fixed to the van frame 1. The bottom of the first side plate 2 is hinged to the bottom plate, and the top of the first side plate 2 is snapped onto the van frame 1. The second side plate 3 is located above the first side plate 2 and is mounted on the van frame 1 via a retractable opening and closing mechanism 4.

[0036] This utility model uses a retractable opening and closing mechanism 4 to control the second side panel 3, so that the side panel can be lifted and retracted when the door is opened. In addition, the side panel is divided into two side panels (the first side panel 2 and the second side panel 3), which reduces the space required when the side panel is opened. This solves the problems of traditional wing-opening vans, such as inconvenience in loading and unloading in narrow spaces, large space occupation when opening the door, and poor adaptability, thereby improving cargo loading and unloading efficiency and expanding the vehicle's usage scenarios.

[0037] like Figure 4 As shown, in one embodiment, the retractable opening and closing mechanism 4 includes a telescopic rod 41, a connecting rod 42, a first sliding groove 43, a first slider 44, a second sliding groove 45, and a second slider 46. The bottom of the telescopic rod 41 is hinged to the carriage frame 1; one end of the connecting rod 42 is hinged to the carriage frame 1, and the middle part of the connecting rod 42 is hinged to the top of the telescopic rod 41; the first sliding groove 43 is disposed on the second side plate 3; the first slider 44 is slidably disposed within the first sliding groove 43, and the first slider 44 is hinged to the other end of the connecting rod 42; the second sliding groove 45 is disposed on the second side plate 3, and the second sliding groove 45 is parallel to the first sliding groove 43; the second slider 46 is slidably engaged within the second sliding groove 45, and the second slider 46 is hinged to the carriage frame 1.

[0038] When the second side panel 3 needs to be opened, the telescopic rod 41 retracts, causing the connecting rod 42 to rotate inward around its hinge point with the carriage frame 1, thereby causing the top of the second side panel 3 to rotate inward and retract. Figure 2 As shown, at this time, the second side plate 3 can slide inward along the first slide groove 43 / second slide groove 45, realizing the inward retraction of the second side plate 3. Therefore, when the second side plate 3 is rotated and opened, if it is restricted by the outer wall, the inward force exerted by the outer wall on the second side plate 3 will cause the second side plate 3 to retract obliquely upward and inward along the first slide groove 43 / second slide groove 45, so that the second side plate 3 can be opened in a relatively narrow space, until it is as shown. Figure 3 As shown, the second side panel 3 is fully open.

[0039] In one embodiment, both the first slide groove 43 and the second slide groove 45 are T-shaped grooves. Setting the first slide groove 43 and the second slide groove 45 as T-shaped grooves effectively prevents the first slider 44 and the second slider 46 from dislodging from the grooves during sliding, improving the stability and safety of the fit between the sliders and the grooves, ensuring the reliability of the retraction opening and closing mechanism 4 during long-term use, avoiding mechanism failures caused by slider dislodging, and extending the service life of the mechanism.

[0040] In one embodiment, the telescopic rod 41 is a hydraulic piston rod. Using a hydraulic piston rod as the telescopic rod 41 offers advantages such as strong power, smooth operation, high control precision, and large load-bearing capacity. This makes the opening and closing action of the second side plate 3 smoother and more powerful, better adaptable to second side plates 3 of different weights and sizes, improves the performance and adaptability of the retraction and opening / closing mechanism 4, and ensures precise control of the side plate opening and closing process.

[0041] In one embodiment, a traction limiting rope 5 is further included. One end of the traction limiting rope 5 is fixed to the carriage frame 1, and the other end of the traction limiting rope 5 is connected to the first side plate 2. The traction limiting rope keeps the first side plate 2 in a horizontal state when it is opened, forming a loading and unloading platform to facilitate loading and unloading operations.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
