Problems solved by technology

[0003] In order to reduce the parking space of small trucks, improve the parking efficiency of the parking lot, enhance the passability of small trucks, alleviate traffic congestion, and reduce the waste of internal space of the car body, the present invention proposes an innovative idea—that is, three-dimensional synchronously telescopic and deformed carriages The idea is to change the main structure of the minivan to simultaneously expand and shrink the size of the vehicle from the three dimensions of length, width and height to realize the deformation of the vehicle, so as to solve some of the current parking difficulties and traffic congestion problems of minivans

Embodiment 1

[0033] Such as figure 1 The small truck shown includes a headstock 1 and a compartment 2, and the compartment 2 is composed of a compartment frame 3 and a compartment wall 4. Such as image 3 As shown, the carriage frame 3 includes a main rod assembly 5 , a double slider assembly 6 , a side rod assembly 7 , a slide rod 8 , and a tie rod assembly 9 . The carriage frame 3 supports the carriage wall 4, and each surface of the carriage wall 4 can be folded.

[0034] Such as Figure 5 As shown, the main rod assembly 5 adopts the principle of a roller screw. The main rod assembly 5 includes left and right motors 11, 11', left and right threaded rods 10, 10', left small sleeve 14, right large sleeve 14', left and right main rod sliders 12, 12'. The motors 11, 11' are respectively placed in the motor bases 22, 22', the outer ends of the motor bases 22, 22' are fixedly connected with the double slider assembly 6, and the motors 11, 11' can drive the threaded rods 10, 10' to rotate....

Embodiment 2

[0043] The difference from Embodiment 1 is the main rod assembly 5 of the carriage frame 3 assembly.

[0044] Such as Figure 8 As shown, the main rod assembly 5 includes a fixed rod 27, a motor 11, a fixed slideway 28, an upper rack 29 and a lower rack 29' with opposite threads. The outer ends of the upper and lower racks 29,29' are respectively fixed on the main rod slider 12,12', and the main rod slider 12,12' can slide freely on the fixed rod 27 simultaneously. The outer end of the fixed rod 27 is fixedly connected with the double slider assembly 6 , and the inner end is provided with a fixed slideway 28 . combine Figure 9 As shown, the fixed slideway 28 is provided with a motor 11, and the inner ends of the two racks 29, 29' can freely pass through the two holes of the fixed slideway 28 and mesh with the motor gear 30 in the motor 11. The left end of tooth bar 29 ' is without sawtooth.

[0045] When the motor 11 rotates and the two racks move toward each other, the t...

Embodiment 3

[0048] combine Figure 10 , 11 As shown, on the coaxial side of the large motor gear 30, a small gear 30' is added. The upper rack 29 meshes with the pinion 30'.

[0049] When the bull gear 30 and the pinion 30' rotate, they drive the upper rack 29 and the lower rack 29' respectively, and the upper and lower racks drive the pull rod 26 to realize the shrinkage of the width and height of the compartment 2. Since the linear velocity of the large gear 30 is greater than that of the pinion 30', the moving speed behind the carriage 2 is slower than the moving speed at the front. Therefore, as figure 2 As shown, when the width and height of the compartment 2 are flexible, the length is also flexible.

Abstract

The invention relates to a freight car capable of automatically deforming. A front side and a rear side of a car body are constructed by adopting a double-slider principle; a main casing pipe and a side casing pipe are combined to form the car body so as to connect the front car body and the rear car body; a rolling shaft leading screw principle is especially ingeniously utilized; a screw rod is driven by a motor to rotate, so as to push a nut to slide, so that a double-quadrangular conic slider is driven to push the synchronous flexibility of the width, height and length of the front side and rear side of the car body, thus the deforming function is realized. The maximum flexibility rate of the freight car can reach 20%, the freight parking space can be saved, and the traffic jam can be relieved. The freight car is suitable for being used in various vehicle types, such as manpower dust carts, manpower express cars and manpower milk cars, and other industrial fields.

Description

technical field [0001] The invention relates to a compartment of a truck, in particular to a deformable compartment of a truck. Background technique [0002] Existing minivan compartments are often not fully loaded or empty, resulting in a waste of interior space. Saving these spaces can relieve traffic pressure. For example, when a single person drives a double-row truck, there is no need for rear The space for the row of seats, if you buy a car suitable for other spaces, it will be a waste of materials and money. There are also some minivan compartments that almost occupy half of the lane on narrow roads, which affect the passage of bicycles on the bicycle lane, and the driving speed is very slow, which will cause congestion. Typical minivans include human-powered garbage trucks, human-powered courier trucks, and human-powered milk delivery trucks, especially garbage trucks. At the beginning, they didn’t carry too much garbage, but the cabin is very high, which hinders th...
