Description

Technical Field

[0001] This invention relates to the field of mechanical technology, and in particular to a truck loading and unloading device for logistics carpooling. Background Technology

[0002] With the rapid development of the logistics industry and electronic information technology, the logistics and transportation industry is increasingly linked with e-commerce. A large number of cargo owners and vehicle owners conduct transactions through the services provided by logistics and transportation e-commerce platforms, which to some extent solves the problems of cargo owners with small batches of goods finding it difficult to find vehicles and vehicle owners having difficulty in reasonably allocating goods.

[0003] For fully enclosed vans, the cargo is stacked from the inside out, and after loading, the goods are often squeezed together.

[0004] Fully enclosed vans are equipped with side and rear doors in the cargo compartment to facilitate loading and unloading by staff. When loading the van, the cargo needs to be distributed reasonably in the cargo compartment according to the cargo specifications to ensure that the van can drive smoothly and safely. In order to avoid the cargo from bumping into each other and making it difficult for staff to unload, the cargo compartment door is usually not filled with cargo, leaving space for staff to unload later.

[0005] Due to the height difference between the truck bed and the ground, when loading and unloading goods, people often place planks on the unloading side of the truck bed to improve loading and unloading efficiency and reduce labor costs. However, whether placing a conveyor belt or laying planks, additional manpower and resources are required to prepare the planks. Summary of the Invention

[0006] In order to improve the situation in related technologies where additional manpower and resources are required for loading and unloading, this application provides a truck loading and unloading device for logistics carpooling.

[0007] This application provides a truck loading and unloading device for logistics carpooling, which adopts the following technical solution:

[0008] A truck loading and unloading device for logistics carpooling includes a truck body and a door. The truck body has a cavity, and the door is installed at the opening of the cavity. The door includes a pressure-bearing part and a limiting part. The pressure-bearing part has a first rotating side that is rotatably connected to the side of the opening of the cavity near the ground.

[0009] The side of the carriage closest to the ground is provided with a drive chamber, and the drive chamber is provided with rollers. The carriage has a through hole connecting the drive chamber and the cavity. The rollers are connected to the pressure-bearing part through a follower component.

[0010] The length of the pressure-bearing part in the direction perpendicular to the first rotating side is greater than the distance from the bottom of the carriage to the ground.

[0011] The compartment door has a closed state, in which the compartment door covers the cavity opening to seal the cavity;

[0012] The door also has a loading and unloading state. In the loading and unloading state, the pressure-bearing part rotates away from the first rotating side until it hangs down to the ground. The follower component controls the roller to be lifted from the drive chamber through the through hole into the cavity under the rotation drive of the pressure-bearing part. The roller abuts against the goods in the cavity.

[0013] Optionally, the limiting part has a second rotating side, the pressure bearing part is rotatably connected to the second rotating side of the limiting part, the limiting part is provided with a first locking tongue, and the end face of the carriage facing the limiting part is provided with a first lock head for the first locking tongue to engage.

[0014] Optionally, a protective railing is provided on the side of the limiting part facing the cavity, and a second locking tongue is provided at the end of the protective railing away from the limiting part. A second lock head is provided on the end face of the carriage facing the limiting part for the second locking tongue to engage.

[0015] Optionally, the drive chamber is provided with a guide block for the roller to slide and partially enter the drive chamber, and the roller is provided with a support shaft. Then the follower assembly includes a first connecting rod fixed to both ends of the first rotation side and a second connecting rod fixed to the support shaft. The follower assembly also includes a follower rod that connects the first connecting rod and the second connecting rod. The drive chamber has limit holes at both ends of the extension direction of the first rotation side, and the follower rod passes through and slides to be connected to the limit holes.

[0016] In the closed state, the roller is located in the drive chamber and on the side of the through hole away from the door, and the follower rod is located at the end of the limiting hole away from the door;

[0017] In the loading and unloading state, the roller part enters the cavity through the through hole, and the follower rod is located at the end of the limiting hole near the door.

[0018] Optionally, an auxiliary foot is provided on the end face of the pressure-bearing part away from the cavity, so that in the loading and unloading state, the end of the auxiliary foot away from the pressure-bearing part abuts against the ground.

[0019] Optionally, the roller has an annular groove for the roller to span over the guide block, the guide block has a guide surface, the bottom wall of the annular groove abuts against the guide surface, and the roller slides along the guide surface under the drive of the second connecting rod.

[0020] By adopting the above technical solution, when loading goods into the carriage, the first locking tongue is removed from the first lock head, and the pressure-bearing part is rotated so that the limiting part is placed on the ground as the pressure-bearing part rotates. The limiting part forms a slope with the ground, allowing workers to push the goods into the carriage along the slope, improving loading efficiency. After loading is completed, the pressure-bearing part is rotated again so that the pressure-bearing part and the limiting part cover the cavity opening, and the first locking tongue is engaged with the first lock head. When unloading, the first locking tongue is removed from the first lock head again, and the pressure-bearing part is rotated. When the end of the pressure-bearing part away from the cavity touches the ground, the angle between the limiting part and the pressure-bearing part is adjusted so that one side of the guardrail abuts against the pressure-bearing part, and the second locking tongue on the guardrail is engaged with the second lock head. When the locking mechanism engages, the pressure-bearing part, the limiting part, and the guardrail form a bucket shape. After the workers push multiple items onto the pressure-bearing part, they release the connection between the first locking tongue and the first locking head, causing the limiting part to rotate away from the pressure-bearing part until it touches the ground. The goods can then slide down the slope formed by the pressure-bearing part and the ground. During loading and unloading, no additional planks are needed, improving unloading efficiency and reducing the manpower and material resources consumed during loading and unloading. When the pressure-bearing part is rotated, from covering the cavity opening to the auxiliary foot touching the ground, the follower component drives the roller part to extend from the through hole to assist the goods in moving out of the carriage. When placing the bottom layer of goods into the carriage, the roller also assists in moving the goods into the carriage. Attached Figure Description

[0030] The technical solutions of various embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Embodiments of the present invention provide a truck loading and unloading device for logistics carpooling, such as... Figures 1 to 7 As shown, the car includes a carriage 1 and a door. The carriage 1 has a cavity 2. The door is installed at the opening of the cavity 2. The door includes a pressure-bearing part 3 and a limiting part 4. The pressure-bearing part 3 has a first rotating side that is rotatably connected to the side of the cavity opening near the ground.

[0032] A drive chamber 5 is provided on the side of the carriage 1 closest to the ground. A roller 6 is provided inside the drive chamber 5. The carriage 1 has a through hole connecting the drive chamber 5 and the cavity 2. The roller 6 is connected to the pressure-bearing part 3 through a follower component.

[0033] The length of the pressure-bearing part 3 in the direction perpendicular to the first rotating side is greater than the distance from the bottom of the carriage 1 to the ground.

[0034] The compartment door has a closed state. In the closed state, the compartment door covers the cavity opening to seal the cavity 2;

[0035] The door also has a loading and unloading state. In the loading and unloading state, the side of the pressure-bearing part 3 away from the first rotating side rotates until it hangs down to the ground. The follower component controls the roller 6 to be lifted from the drive chamber 5 through the through hole into the cavity 2 under the rotation drive of the pressure-bearing part 3. The roller 6 abuts against the goods in the cavity 2.

[0036] Specifically, in this embodiment, when closed, the roller 6 does not extend beyond the through hole.

[0037] The pressure-bearing part 3 is made of high-strength alloy material so that it can withstand the pressure of the goods placed on the pressure-bearing part 3 during loading and unloading.

[0038] When the cargo door is in the loading / unloading state, the roller 6 extends beyond the through hole into the cavity 2. When the staff needs to load cargo, they push the cargo onto the pressure-bearing part 3, and then push the cargo along the slope formed by the pressure-bearing part 3 to push the cargo into the carriage 1. As the cargo moves from the side of the carriage 1 near the door to the side away from the door, the roller 6 is located below the cargo and abuts against the cargo. The roller 6 rolls with the cargo, which helps to move the cargo at the bottom of the carriage 1 into the carriage 1 and improves loading efficiency.

[0039] During unloading, the goods are pushed from inside the carriage 1 to the opening, and then pushed down along the pressure section 3 to the ground. During this process, the rollers 6 assist the goods located at the bottom of the carriage 1 to be moved out of the carriage 1, thus improving unloading efficiency.

[0040] Staff do not need to configure additional loading and unloading slats; simply opening the cargo door will provide the necessary assistance, reducing the manpower and resources required for loading and unloading.

[0041] In a preferred embodiment of the present invention, the limiting part 4 has a second rotating side, the pressure bearing part 3 is rotatably connected to the second rotating side of the limiting part 4, the limiting part 4 is provided with a first locking tongue, and a first lock head 9 for the first locking tongue to engage is provided on the end face of the carriage 1 facing the limiting part 4.

[0042] Specifically, in this embodiment, the first locking tongue is a support piece 8 that is rotatably connected to the limiting part 4 via a rotating shaft. The first lock head 9 is fixed on the side of the carriage 1 adjacent to the carriage door. The first lock head 9 has a lock hole 22, and the support piece 8 has a support hole 21 for the first lock head 9 to pass through. In the closed state, the support piece 8 is sleeved on the first lock head 9, and a padlock is provided on the lock hole 22 to prevent the support piece 8 from coming off the first lock head 9.

[0043] In a preferred embodiment of the present invention, a protective railing 10 is provided on the side of the limiting part 4 facing the cavity 2, and a second locking tongue is provided at the end of the protective railing 10 away from the limiting part 4. A second lock head is provided on the end face of the carriage 1 facing the limiting part 4 for the second locking tongue to engage.

[0044] Specifically, in this embodiment, the second locking tongue includes a T-shaped locking pin 11 and a tension spring 12. The second lock head is a first insertion hole 23 opened in the carriage 1. The guardrail 10 has a second insertion hole 24 for the T-shaped locking pin 11 to pass through. One end of the tension spring 12 is fixed at the opening of the second insertion hole 24. The T-shaped locking pin 11 passes through the tension spring 12 and the second insertion hole 24 in sequence. The T-shaped part of the T-shaped locking pin 11 is located on the side of the guardrail 10 where the tension spring 12 is provided, and the other end of the tension spring 12 is fixed on the side of the T-shaped part close to the guardrail 10.

[0045] In the closed state, the guardrail 10 is located inside the cavity 2, and one end of the T-shaped locking pin 11 abuts against the cavity wall. At this time, the tension spring 12 is compressed. When adjusting from the closed state to the loading / unloading state, the limiting part 4 moves with the pressure bearing part 3 as it rotates, and the guardrail 10 is partially pulled out from the cavity 2 along with the limiting part 4. The guardrail 10 then gradually moves downwards and away from the cavity 2. In the loading / unloading state, the side of the guardrail 10 closest to the ground abuts against the side of the pressure bearing part 3 away from the ground. The T-shaped locking pin 11 moves and engages in the first insertion hole 23 of the carriage 1. At this time, the tension spring 12 returns to its original position. Since one end of the tension spring 12 is fixed to the guardrail 10, the tension spring 12 can press the T-shaped part of the T-shaped locking pin 11 into the first insertion hole 23, reducing the probability of the T-shaped locking pin 11 coming out of the first insertion hole 23.

[0046] In a preferred embodiment of the present invention, a guide block 13 is provided in the drive chamber 5 for the roller 6 to slide and partially enter the drive chamber 5. The roller 6 is provided with a support shaft 14. The follower assembly includes a first connecting rod 15 fixed to both ends of the first rotation side and a second connecting rod 16 fixed to the support shaft 14. The follower assembly also includes a follower rod 17 that connects the first connecting rod 15 and the second connecting rod 16 respectively. Limiting holes 18 are provided at both ends of the extension direction of the first rotation side of the drive chamber 5. The follower rod 17 passes through and slides to be connected to the limiting holes 18.

[0047] In the closed state, the roller 6 is located inside the drive chamber 5 and on the side of the through hole away from the door, and the follower rod 17 is located at the end of the limiting hole 18 away from the door;

[0048] In the loading and unloading state, part of the roller 6 enters the cavity 2 through the through hole, and the follower rod 17 is located at the end of the limit hole 18 near the door.

[0049] In a preferred embodiment of the present invention, the roller 6 is provided with an annular groove 20 for the roller 6 to span across the guide block 13. The guide block 13 has a guide surface, and the bottom wall of the annular groove 20 abuts against the guide surface. The roller 6 slides along the guide surface under the drive of the second connecting rod 16.

[0050] Specifically, in this embodiment, the limiting hole 18 is waist-shaped and inclined. The end of the limiting hole 18 near the door is set away from the ground, and the end of the limiting hole 18 away from the door is set away from the ground.

[0051] The guide surface is positioned away from the ground on the side near the cavity opening of cavity 2, and the guide surface is positioned near the ground on the side away from the cavity opening of cavity 2.

[0052] During the transition from the loading / unloading state to the closed state, the pressure-bearing part 3 gradually engages with the cavity opening. At this time, the end of the first connecting rod 15 away from the pressure-bearing part 3 slides to the end of the limiting hole 18 away from the pressure-bearing part 3 as the pressure-bearing part 3 moves. The follower rod 17 moves with the first connecting rod 15 and drives the second connecting rod 16 away from the cavity opening of the cavity 2. The roller 6 moves to the side of the guide block 13 away from the door.

[0053] During the transition from the closed state to the loading / unloading state, the end of the pressure-bearing part 3 away from the ground rotates away from the carriage 1 and falls to the ground. At this time, the end of the first connecting rod 15 away from the pressure-bearing part 3 slides to the end of the limiting hole 18 near the pressure-bearing part 3 as the pressure-bearing part 3 moves. The follower rod 17 moves with the first connecting rod 15 and drives the second connecting rod 16 to approach the cavity opening of the cavity 2. The roller 6 then moves to the side of the guide block 13 near the door, so that the part of the roller 6 away from the ground extends beyond the through hole and enters the cavity 2.

[0054] In a preferred embodiment of the present invention, an auxiliary foot 19 is provided on the end face of the pressure-bearing part 3 away from the cavity 2, so that in the loading and unloading state, the end of the auxiliary foot 19 away from the pressure-bearing part 3 abuts against the ground.

[0055] A first door hinge is fixed on the bottom wall of the carriage 1. The pressure-bearing part 3 has a first slot for the first door hinge to be inserted into, that is, the side of the pressure-bearing part 3 with the first slot is the first rotating side. A second door hinge is fixed on the side of the pressure-bearing part 3 away from the first rotating side. The limiting part 4 has a second slot for the second door hinge to be inserted into, that is, the side of the limiting part 4 with the second slot is the second rotating side.

[0056] When loading goods into the carriage 1, the first locking tongue is removed from the first lock head 9, and the pressure-bearing part 3 is rotated so that the limiting part 4 is placed on the ground. The limiting part 4 forms a ramp with the ground, allowing workers to push the goods into the carriage 1 along the ramp, improving loading efficiency. After loading is complete, the pressure-bearing part 3 is rotated again so that the pressure-bearing part 3 and the limiting part 4 cover the opening of the cavity 2, and the first locking tongue is engaged with the first lock head 9. When unloading, the first locking tongue is removed from the first lock head 9 again, and the pressure-bearing part 3 is rotated. When the end of the pressure-bearing part 3 away from the cavity 2 touches the ground, the angle between the limiting part 4 and the pressure-bearing part 3 is adjusted so that one side of the guardrail 10 abuts against the pressure-bearing part 3, and the second locking tongue on the guardrail 10 is engaged with the second lock head. At this time, the pressure-bearing part 3, the limiting part 4, and the guardrail 10 are in the shape of a bucket. After the staff pushes multiple goods onto the pressure-bearing part 3, they release the connection between the first locking tongue and the first locking head 9, so that the limiting part 4 rotates away from the pressure-bearing part 3 until the limiting part 4 touches the ground. The goods can then slide down the slope formed by the pressure-bearing part 3 and the ground. When loading and unloading, there is no need to prepare additional slats, which improves the unloading efficiency and reduces the manpower and material resources consumed during loading and unloading. When the pressure-bearing part 3 is rotated so that it changes from the state of covering the cavity opening to the state of the auxiliary foot 19 touching the ground, the follower component drives the roller 6 to extend out from the through hole to assist the goods in moving out of the carriage 1. When placing the bottom layer of goods into the carriage 1, the roller 6 also assists in moving the goods into the carriage 1.
