Description

Technical Field

[0001] This utility model relates to the field of tricycle equipment technology, specifically to a tricycle carriage structure. Background Technology

[0002] As an important tool for short-distance logistics transportation, the cargo capacity of tricycles directly affects transportation efficiency. Traditional tricycle cargo boxes typically use a fixed panel structure, with non-expandable side panels and rear panels, resulting in the actual cargo area being limited by the floor size. To increase cargo capacity, existing technologies attempt to add hinge structures to the bottom of the side panels, allowing them to fold outwards. However, the side panels only droop down via the hinges, forming an acute angle with the floor. This makes it easy for goods to slip off, and the effective cargo area is not substantially increased. Therefore, we propose a tricycle cargo box structure. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a three-wheeled vehicle body structure to solve the problems existing in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A three-wheeled vehicle body structure includes a floor, side panels, and a rear panel. The bottom of the side panels is connected to the side of the floor via hinges. A fixing seat is provided on the inner side wall of the side panels, and the fixing seat is connected to a support shaft extending obliquely. The axis of the support shaft points towards the front rear panel. The vehicle also includes a traction chain, one end of which is fixed to the front rear panel, and the other end is provided with a waist hole sleeve, which is fitted onto the support shaft. When the side panels are unfolded outward, the traction chain pulls the side panels obliquely to keep them horizontal with the floor.

[0006] Preferably, the support shaft has a raised structure in the middle, and its surface is smoothly connected to the fixed seat.

[0007] Preferably, a limiting piece is provided at one end of the support shaft near the front back panel, and the area of ​​the waist-shaped hole of the waist hole sleeve is larger than the cross-sectional area of ​​the limiting piece;

[0008] When the side panel is unfolded, the waist hole sleeve and the limiting piece are staggered.

[0009] Preferably, the rear of the bottom plate is provided with a straight groove arranged along the front-to-back direction of the carriage, and a sliding rod is slidably installed in the groove;

[0010] Multiple sliding rods are connected to the base, and the base is hinged to the rear tail plate.

[0011] Preferably, the rear tail plate moves along a straight groove via a sliding rod driven by the base, thereby extending the length of the tail section of the bottom plate.

[0012] Preferably, the bottom plate has downwardly extending side plates on both sides near the rear tail plate, and the rear flap plate is connected between the two side plates.

[0013] Preferably, at least two reinforcing ribs are provided between the rear cover plate and the bottom of the base plate.

[0014] This utility model provides a three-wheeled vehicle carriage structure. It has the following beneficial effects:

[0015] 1. Through the bottom hinge design of the side plate and the bottom plate, combined with the diagonal fixation of the traction chain and support shaft, the side plate can be made to remain horizontal with the bottom plate after it is unfolded outward, thereby increasing the cargo area.

[0016] 2. The rear tail panel is linked to the base and sliding rod, which can be stretched backward to extend the length of the rear of the bottom panel, further increasing the cargo space. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, what is described is only a part of this utility model, not all of it. Based on this utility model, all other inventions obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] See attached document Figure 1-5A three-wheeled vehicle body structure includes a three-door body formed by a floor plate 1, left and right side plates 11, a rear tail plate 12, and a front back plate. Side plates extending downward are connected to the two side walls of the floor plate 1 near the rear tail plate 12. The side plates are connected by the same rear cover plate 13. At least two reinforcing ribs 14 are also connected between the rear cover plate 13 and the bottom of the floor plate 1 for reinforcement and fixation.

[0025] The bottom edge of the side plate 11 is connected to the side of the base plate 1 via a hinge, allowing the side plate 11 to be opened to both sides. A fixing seat 3 is installed on the inner side wall of the side plate 11, and a support shaft 31 is also connected to the fixing seat 3. A limiting piece 32 is also connected to the support shaft 31 near the front back plate. The axial end of the support shaft 31 points towards the front back plate. The support shaft 31 is located in the middle of the fixing seat 3, forming a raised structure. The raised structure can increase the connection area between the support shaft 31 and the fixing seat 3, improve the overall strength of the two, and also reduce the sharp edges, thus mitigating material damage caused by collisions when loading. In addition, when the carriage is closed, the limiting piece 32 is perpendicular to the base plate 1 and has a strip-shaped structure.

[0026] It also includes a traction chain 2 with one end fixedly installed on the front back panel, and a waist hole sleeve 21 fixedly installed on the other end of the traction chain 2. The waist hole sleeve 21 has a waist-shaped hole, and the area of ​​the waist-shaped hole of the waist hole sleeve 21 is larger than the area of ​​the limiting piece 32. The waist hole sleeve 21 passes through the limiting piece 32 and is sleeved on the support shaft 31. The support shaft 31 is used to hang the waist hole sleeve 21. When the side panel 11 of the carriage is unfolded, the traction chain 2 pulls the side panel 11 diagonally so that the side panel 11 is parallel to the bottom plate 1, increasing the bearing area. At this time, the waist hole sleeve 21 and the limiting piece 32 are in an interlaced state to prevent the waist hole sleeve 21 from falling off the limiting piece 32.

[0027] To further expand the load-bearing area, multiple straight grooves are provided on the rear of the base plate 1. The straight grooves are arranged along the front and rear direction of the carriage. Sliding rods 41 are slidably installed in the straight grooves. Multiple sliding rods 41 are connected to the same base 4. The base 4 is hinged to the rear tail plate 12. When the sliding rods 41 move along the straight grooves of the base plate 1, the base 4 drives the rear tail plate 12 to extend outward.
