Description

Technical Field

[0002] In recent years, with the rapid development of e-commerce and logistics industries, logistics transport vehicles have become an important tool in the logistics and transportation industry. Among all types of cargo transport vehicles, large and medium-sized logistics transport vehicles generally use larger loading and unloading machinery such as electric forklifts to load and unload goods due to the large and concentrated cargo volume; while small and medium-sized logistics transport vehicles have a small cargo volume and small cargo compartment space, and cannot use loading machinery to load and unload goods, so they can only rely on manual loading and unloading. With the sharp increase in cargo volume, it is necessary to shuttle back and forth throughout the entire compartment to move the goods in or out of the compartment one by one, which is time-consuming and labor-intensive, and inefficient.

[0003] On the other hand, when loading and unloading small and medium-sized logistics transport vehicles, it is often necessary to carry large goods or heavy items onto or unload the vehicle, which is very unfriendly to thin people or girls.

When the atomic box unit 3 rotates to the top of the bearing platform 11 with the flip unit 2, it can play a supporting and guiding role to ensure that the cargo bearing surface is in a horizontal state when loading is completed.

[0079] The embodiment of the present application provides a logistics transport vehicle that is convenient for loading and unloading goods. A flip unit is installed on the side edge of the chassis unit. The flip unit is manually rotated to flip the atomic box unit fixed on the flip unit to above the load-bearing platform. Heavier items can be loaded and unloaded on the vehicle without the aid of additional auxiliary tools, thereby greatly improving efficiency and not requiring electricity or the use of additional power structures such as hydraulics and pneumatics.

[0084] In one embodiment, if Figure 5 and Figure 6 As shown, the slide assembly 26 includes a slide bracket 261, a synchronous rotating shaft 264, a composite roller bearing 265, a gear 266, a clamping elastic member 267 and a rack 268, etc.; wherein, a rotating shaft mounting hole 262 is provided at the position where the slide bracket 261 cooperates with the rotating shaft 22, and the rotating shaft 22 passes through the rotating shaft mounting hole 262 to complete the rotational connection with the slide assembly 26; a force storage elastic member fixing hole 263 is provided at the position where the slide bracket 261 cooperates with the force storage elastic member 23 to complete the fixation of one end of the force storage elastic member 23; the synchronous rotating shaft 264 passes through the slide bracket 261 and the two ends extend out to install the gear 266; the composite roller bearing 265 is symmetrically arranged on both sides of the slide bracket 261 and placed inside the guide rail 251, and can move back and forth smoothly and stably inside the guide rail 251. It adopts the existing products on the market and will not be described here; the gear 266 is symmetrically arranged at both ends of the synchronous shaft 264; one end of the clamping elastic member 267 is sleeved on the synchronous shaft 264 and the other end is connected to the slide bracket 261; the rack 268 is fixedly installed on one side of the guide rail 251 and meshes with the gear 266. In this embodiment, the clamping elastic member 267 adopts a spring, and the tension of the spring can ensure that the gear 266 always has a pulling force toward the rack 268 side to better mesh with the rack 268, so that the operation is more stable without gaps and shaking; in other embodiments, the clamping elastic member 267 can also be made of elastic belts or other elastic materials.

When loading is required, the user can pass his hand through the avoidance groove 256 and pull the unlocking rod 281, and under the linkage action of the wire rope 285, the lock 286 is rotated to a certain angle, thereby loosening from the lock seat 288 and completing the unlocking to complete the flip loading operation; when unloading is required, when the guide rail 251 is rotated to be perpendicular to the supporting platform 11, the lock 286 is clamped with the lock seat 288 under the action of the lock reset member 287, completing the locking, and preventing the L-shaped bracket 25 from flipping upward under the action of the force storage elastic member 23.

[0086] In one embodiment, if Fig.10 As shown, the chassis unit 1 also includes a chassis frame 12 and a wheel 13 arranged at the bottom of the chassis frame 12. The chassis frame 12 is provided with an electric control cabin 14, an emergency stop button 15, a first sensor 16, a second sensor 17 and a third sensor 18 on its periphery. In this embodiment, the wheel 13, the electric control cabin 14, the emergency stop button 15, the first sensor 16, the second sensor 17 and the third sensor 18 are all based on existing technologies, which will not be described in detail here.

In other embodiments, it can also be set to multiple groups, such as two groups or four groups.

[0088] It should be noted that the atomic box unit 3 and the flip unit 2 are not combined one-to-one, but can be combined randomly. For example, after a fully loaded atomic box unit 3 is unloaded, an empty atomic box unit 3 can be loaded, which is very flexible in application.

[0089] In one embodiment, the atomic box unit 3 further includes a plurality of handles 33 disposed between the box support 31 and the cover 32, so as to provide a gripping position when flipping the box, preferably without sacrificing the inner cavity space of the box.

[0090] In one embodiment, the atomic box unit 3 also includes one or more partitions 34 detachably arranged in the inner cavity of the box support 31 to divide the accommodating space into a number of sub-spaces.

[0093] Preferably, the cover 32 is any one of a sealing plate or a mesh surface or a combination of the two; when the atomic box unit 3 needs to be completely closed, a sealing plate can be used, otherwise a mesh surface or a combination of the two can be used. In order to reduce the overall weight of the atomic box unit 3, PP honeycomb panels, nylon waterproof cloth or fine metal wire mesh can be used to save effort or load more goods while ensuring strength.

[0095] It should be noted that the support unit 4 is used in conjunction with the flip unit 2, adopts a modular design, and is detachably installed. It can be a set arranged on one side of the chassis unit 1, or multiple sets can be arranged on one side of the chassis unit 1. They can also be distributed on different sides and staggered with each other, which is very flexible to use.

[0096] When used specifically, Fig.15 As shown, first, place the goods to be transported into the atomic box unit 3, push the atomic box unit 3 so that its docking surface faces the flip unit 2 on the side of the carrying platform 11, and the user steps on the foot pedal 36 to lift the side of the atomic box unit 3 close to the flip unit 2, thereby inserting the limit rod 312 into the limit groove 255, and at the same time, the support rod 311 is inserted into the elastic limit seat 27. At this time, the force storage elastic member 23 is in the maximum force storage state, and the locking assembly 28 is in the locked state. At this point, the combination of the atomic box unit 3 and the flip unit 2 is completed, and the atomic box unit 3 and the flip unit 2 are in a vertical state, which can also be said to be the first workstation.

[0097] The user can put his hand through the escape groove 256 and pull the unlocking rod 281, so that the lock buckle 286 can rotate to a certain angle under the linkage action of the wire rope 285, thereby releasing the lock buckle seat 288 and completing the unlocking.

At the same time, under the joint action of the force storage elastic member 23, the atomic box unit 3 can be more easily flipped 90 degrees to the top of the carrying platform 11. The atomic box unit 3 continues to rotate upward and pushes forward to the end. At this time, the upper end surface of the atomic box unit 3 is parallel to the carrying platform 11, that is, it is in a flat state, which can also be said to be the second workstation. At this time, the L-shaped bracket 25 slides along the guide slope 44 until it contacts the support plane 43, and the conical rubber block 42 is inserted into the conical rubber block fixing hole 254, and the loading is completed.

[0099] The chassis unit 1 carries one or more atomic box units 3 to the next station, and is also unloaded manually; the unloading process is reversed to the loading process, which will not be described in detail here; it should be noted that when the guide rail 251 rotates to be perpendicular to the load-bearing platform 11, the slide assembly 26 moves to the end of the L-shaped bracket 25 close to the second limit plate 253, and the lock 286 is clamped with the lock seat 288 under the action of the lock reset member 287. At this time, the atomic box unit 3 is removed, and the flip unit 2 will not flip upwards under the action of the locking assembly 28, and waits for the next loading in this state. The switching of the flip unit 2 between the first station and the second station completes the loading and unloading of the atomic box unit 3 and its internal goods.

[0100] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
