Description
Technical Field
[0001] This application relates to the field of semi-trailer transportation, and in particular to a foldable multi-functional cargo van. Background Technology
[0002] The cargo box truck is mainly used for transporting special cargo in a box-like manner. In terms of exterior design, it strives for an aesthetically pleasing appearance, a reasonable internal structure, and advanced technology. It uses high-quality steel as the frame and is welded in strict accordance with industry standards. The box panels are pressed into a corrugated shape using tooling fixtures, which has high strength. It also features light weight, semi-removable or fully removable box railings, easy lifting and lowering, convenience, practicality, safety, and reliability.
[0003] Cargo semi-trailers are lightweight and portable, thus holding a place in the cargo transportation field, primarily used for transporting agricultural and sideline products and other light goods. With the development of the logistics industry, various goods need to circulate nationwide to achieve resource utilization upon arrival at their destination. However, due to the limitations of cargo semi-trailers, some goods, such as large equipment, cannot be transported. These goods can only be transported using flatbed trucks. Flatbed trucks, due to their special body structure, are generally unsuitable for transporting ordinary light goods for cost and convenience considerations. Each vehicle type has its limitations, causing some models to be unable to operate during industry downturns. This not only wastes resources but also causes significant inconvenience for vehicle owners, resulting in high maintenance costs and decreased income. Utility Model Content
[0004] To diversify the cargo transported by the cargo wagon, this application provides a foldable multi-functional cargo wagon.
[0005] This application provides a foldable, multi-functional cargo cart with a manhole cover, which adopts the following technical solution:
[0006] A foldable multi-functional cargo van with a trough includes a front and a body. The body includes a bottom support frame, a floor plate, and a trough. The floor plate is mounted on the bottom support frame. A sliding groove is provided on the bottom support frame along its length, and the trough is slidably disposed in the sliding groove.
[0007] The trough is a foldable trough. When the trough slides on the slide, it can switch between a folded state and an unfolded state. When the trough is in the folded state, it is positioned close to the front of the vehicle.
[0008] By adopting the above technical solution, when transporting ordinary goods, the trough is in an unfolded state, with the goods loaded on the vehicle floor and located inside the trough. When transporting large goods, the trough is switched to a folded state, so that the folded trough is close to the front of the vehicle, leaving sufficient space for the vehicle body. The cargo wagon is switched to a flatbed wagon, providing the vehicle with more transportation opportunities. This allows the vehicle to change its type by changing the state of the trough when facing different goods, thus adapting to the transportation of various types of goods.
[0009] Preferably, the manger includes multiple folding doors, which are connected by locking rods. The locking rods are arranged along the length of the folding doors and pass through the interior of the folding doors. A first locking pin is provided on the locking rod to fix the locking rod.
[0010] By adopting the above technical solution, the locking rod is installed along the length of the folding door, connecting multiple folding doors together to form an integral structure. This makes the connection between the folding doors closer together. The movable locking rod, combined with the first locking pin, allows the locking rod to be flexibly moved and adjusted in position when needed, thereby changing the unfolding angle of the folding door and the internal space layout of the trough, improving its adaptability to goods during transportation. When the trough needs to be folded, the movable locking rod can be easily moved to the appropriate position, allowing the folding doors to be folded more tightly together, reducing the overall space occupied by the trough. As a key component connecting the folding doors, the movable locking rod, after being fixed by the first locking pin, can provide reliable support and connection when the trough is unfolded and used, ensuring that the connection between the folding doors is tight and stable, preventing the folding doors from loosening, deforming, or accidentally opening due to vehicle bumps or shaking during transportation, thus ensuring safety.
[0011] Preferably, the locking rod can reciprocate along the height direction of the folding door. When the locking rod moves away from the vehicle floor, the locking rod lifts the first locking pin, and after the first locking pin is lifted, the two adjacent folding doors are disconnected.
[0012] By adopting the above technical solution, when the first locking pin is installed on the locking rod, the locking rods on two adjacent folding doors are fixed by the first locking pin. When it is necessary to open the trough from the side, the first locking pin at the connection point of any two adjacent folding doors on the side of the trough is lifted by the locking rod. At this time, the two adjacent folding doors are disconnected, and both folding doors rotate along the connection point with other folding doors, and the folding doors can be opened. When it is necessary to replace the folding doors, simply move multiple locking rods away from the vehicle floor, and the locking rods will automatically lift the first locking pin, disconnecting each adjacent folding door, which can quickly complete the disassembly of the folding doors.
[0013] Preferably, a second locking pin is provided at one end of the locking rod near the bottom support frame. The second locking pin can be switched between a fixed state and an open state. When the second locking pin is in the fixed state, the folding door is fixedly installed with the bottom support frame. When the second locking pin is open, the folding door slides in the slide groove.
[0014] By adopting the above technical solution, when the second locking pin is in the fixed state, the folding door is tightly connected to the bottom support frame, making the entire manger a stable whole structure that remains stable during transportation. This fixing method helps to evenly distribute the various forces borne by the manger onto the entire bottom support frame. When it is necessary to transport goods or change the position of the manger, the second locking pin is switched to the open state, and the folding door can slide freely in the slide, making it convenient to adjust the position of the manger or to perform folding operations, so that the vehicle can adapt to a variety of transportation tasks.
[0015] Preferably, the second locking pin includes a column slide rod fixedly connected to the locking rod, and a column locking plate installed at the bottom of the slide groove. Both the bottom of the slide groove and the column locking plate have multiple locking holes for fixing the column slide rod.
[0016] By adopting the above technical solution, multiple lock holes are provided at the bottom of the chute and on the column locking plate. During transportation, the column slide rod can be fixed in different lock holes, thereby adjusting the relative position between the folding door and the bottom support frame, flexibly changing the internal space layout of the chute to adapt to transport objects of various sizes. The column slide rod is fixedly connected to the locking rod and is fixed by cooperating with the lock holes on the column locking plate and the bottom of the chute. This double-fixing structure makes the connection between the folding door and the bottom support frame more stable. The distribution of multiple lock holes can make the force distribution more uniform when the column slide rod is fixed in different positions. When the chute is subjected to external force, the force can be distributed to the entire structure through different lock holes and column slide rods, avoiding excessive local stress that could lead to component damage.
[0017] Preferably, the lock holes on the column locking plate are evenly distributed, and the lock holes at the bottom of the slide groove correspond to the lock holes on the column locking plate.
[0018] By adopting the above technical solution, the lock holes on the column locking plate are evenly arranged, which ensures higher relative positional accuracy between the folding door and the bottom support frame each time the column slide bar is inserted into the lock hole for fixing. The lock holes at the bottom of the slide groove correspond to the lock holes on the column locking plate, further enhancing the accuracy of fixing. The one-to-one correspondence avoids installation difficulties or insecure fixing caused by mismatched lock hole positions.
[0019] Preferably, the end of the vehicle body away from the front is the rear, and a folding ladder is provided at the rear, which can be folded and stored in the bottom support frame.
[0020] By adopting the above technical solution, the folding ladder can be stored in the bottom support frame after folding, which makes full use of the space at the rear of the vehicle, avoids the ladder occupying extra space, makes the space layout of the vehicle more reasonable during transportation, improves the vehicle's cargo capacity, and also reduces the risk of damage to the ladder caused by external objects colliding with it during vehicle operation, thus helping to extend the service life of the ladder.
[0021] Preferably, the bottom of the folding ladder is equipped with at least one roller, and the end of the bottom support frame is provided with a baffle to intercept the roller.
[0022] By adopting the above technical solution, the bottom of the folding ladder is equipped with rollers, which makes it easier to move the ladder when unfolding or folding it up. When the ladder needs to be unfolded, it is pushed through the rollers to smoothly move the ladder out of the bottom support frame. When folding the ladder, the rollers also help the ladder return to its position in the bottom support frame more accurately. The baffle at the end of the bottom support frame is used to intercept the rollers, which can effectively prevent the ladder from overstretching or falling out of the bottom support frame during unfolding. At the same time, during vehicle transportation, the baffle can prevent the rollers from rolling, thereby preventing the ladder from shifting within the bottom support frame.
[0023] Preferably, the folding ladder is evenly divided into three parts. The folding ladder can be switched between a folded state and an unfolded state. When the folding ladder is in the folded state, the two sides of the folding ladder are folded and stored in the middle part.
[0024] By adopting the above technical solution, the folding ladder is evenly divided into three parts, and the two side parts can be folded and stored in the middle part. In the folded state, the overall shape of the folding ladder is more compact, and the space occupied when stored in the bottom support frame is reduced.
[0025] Preferably, a folding ladder storage door is provided at the end of the bottom support frame away from the front of the vehicle, and a folding ladder storage door lock is provided on the folding ladder storage door.
[0026] By adopting the above technical solution, the folding ladder storage door can protect the folding ladder placed in the bottom support frame, effectively preventing dust, rainwater, etc. from entering the bottom support frame and coming into contact with the folding ladder. If the storage door is suddenly opened while driving, the folding ladder may slip down, posing a serious safety threat to other vehicles and pedestrians on the road. The folding ladder storage door lock can ensure that the folding ladder storage door will not be opened accidentally while the vehicle is in motion.
[0027] In summary, this application includes at least one of the following beneficial technical effects:
[0028] 1. When transporting ordinary goods, the trough is in the unfolded state, with the goods loaded on the floor and located inside the trough. When transporting large goods, the trough is switched to the folded state, so that the folded trough is close to the front of the vehicle, leaving sufficient space for the vehicle body. The cargo wagon is switched to a flatbed wagon, providing more transportation opportunities for the vehicle. This allows the vehicle to change its type by changing the state of the trough when facing different goods, thus adapting to the transportation of various types of goods.
[0029] 2. When the trough needs to be folded, the movable locking bar can be easily moved to the appropriate position, allowing the folding door to be folded more tightly together, reducing the overall space occupied by the trough. As a key component connecting the folding door, the movable locking bar, after being fixed by the first locking pin, can provide reliable support and connection when the trough is unfolded and used, ensuring that the connection between the folding doors is tight and stable, preventing the folding doors from loosening, deforming, or accidentally opening due to vehicle bumps, shaking, etc. during transportation, thereby ensuring safety.
[0030] 3. When the first locking pin is installed on the locking rod, the locking rods on two adjacent folding doors are fixed by the first locking pin. When it is necessary to open the trough from the side, the first locking pin at the connection point of any two adjacent folding doors on the side of the trough is lifted by the locking rod. At this time, the two adjacent folding doors are disconnected, and both folding doors rotate along the connection points with other folding doors, and the folding doors can be opened. When it is necessary to replace the folding doors, simply move multiple locking rods away from the vehicle floor, and the locking rods will automatically lift the first locking pin, disconnecting each adjacent folding door, which can quickly complete the disassembly of the folding doors.

Detailed Implementation
[0039] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.
[0040] This application discloses a foldable multi-functional cargo van with a trough 3. The foldable multi-functional cargo van with a trough 3 includes a front end and a body 01. The body 01 includes a bottom support frame 1, a floor plate 2, and a trough 3. The floor plate 2 is mounted on the bottom support frame 1. A sliding groove 11 is provided along the length of the bottom support frame 1, and the trough 3 is slidably disposed within the sliding groove 11. The trough 3 is foldable, and can switch between a folded state and an unfolded state when sliding on the sliding groove 11. When the trough 3 is in the folded state, it is positioned close to the front end of the vehicle. In an optional embodiment, the cargo van is 12.5 meters long, and when the trough 3 is in the folded state, its folded length is 1 meter.
[0041] In an optional embodiment, the trough 3 includes multiple folding doors 31 connected by locking rods 32. The locking rods 32 are arranged along the length of the folding doors 31 and penetrate through the interior of each folding door 31. A first locking pin 33 is provided on the locking rod 32 to fix it in place. The locking rods 32, extending through the length of the folding doors 31, connect the multiple folding doors 31 together to form a single structure, making the connection between the folding doors 31 closer together. The movable locking rods 32, combined with the first locking pins 33, allow the locking rods 32 to be flexibly moved and adjusted in position when needed, thereby changing the unfolding angle of the folding doors 31 and the internal spatial layout of the trough 3, improving its adaptability to goods during transportation.
[0042] Optionally, when the trough 3 needs to be folded, the movable locking rod 32 can be easily moved to a suitable position, so that the folding door 31 can be folded together more tightly, reducing the overall space occupied by the trough 3. As a key component connecting the folding door 31, the movable locking rod 32, after being fixed by the first locking pin 33, can provide reliable support and connection when the trough 3 is unfolded and used, ensuring that the connection between the folding doors 31 is tight and stable, preventing the folding doors 31 from loosening, deforming or accidentally opening due to vehicle bumps, shaking or other reasons during transportation, thereby ensuring safety.
[0043] In an optional embodiment, the locking rod 32 can reciprocate along the height direction of the folding door 31. When the locking rod 32 moves away from the vehicle floor 2, it lifts the first locking pin 33, disconnecting the two adjacent folding doors 31. When the first locking pin 33 is installed on the locking rod 32, the locking rods 32 on the two adjacent folding doors 31 are fixed by the first locking pin 33. When it is necessary to open the trough 3 from the side, the locking rod 32 at the connection point of any two adjacent folding doors 31 on the side of the trough 3 lifts the first locking pin 33 at that point, disconnecting the two adjacent folding doors 31. Both folding doors 31 rotate along the connection point with other folding doors 31, allowing the folding doors 31 to be opened. When it is necessary to replace the folding door 31, simply move the multiple locking rods 32 away from the vehicle floor 2, and the locking rods 32 automatically lift the first locking pin 33, disconnecting each adjacent folding door 31, thus quickly completing the disassembly of the folding door 31.
[0044] Optionally, a second locking pin 34 is provided at one end of the locking rod 32 near the bottom support frame 1. The second locking pin 34 can be switched between a fixed state and an open state. When the second locking pin 34 is in the fixed state, the folding door 31 is fixedly installed with the bottom support frame 1. When the second locking pin 34 is open, the folding door 31 slides within the slide groove 11. Preferably, when the second locking pin 34 is in the fixed state, the folding door 31 is tightly connected to the bottom support frame 1, making the entire trough 3 a stable integral structure that remains stable during transportation. This fixing method helps to evenly distribute the various forces borne by the trough 3 onto the entire bottom support frame 1. When it is necessary to transport goods or change the position of the trough 3, the second locking pin 34 is switched to the open state, and the folding door 31 can slide freely within the slide groove 11, facilitating the adjustment of the position of the trough 3 or folding operations, enabling the vehicle to adapt to various transportation tasks.
[0045] In a preferred embodiment, the second locking pin 34 includes a column slide bar 341 fixedly connected to the locking rod 32, and a column locking plate 342 installed at the bottom of the slide groove 11. Multiple locking holes 343 for fixing the column slide bar 341 are provided on both the bottom of the slide groove 11 and the column locking plate 342. The locking holes 343 on the column locking plate 342 are evenly distributed, and the locking holes 343 at the bottom of the slide groove 11 correspond to the locking holes 343 on the column locking plate 342. The even distribution of the locking holes 343 on the column locking plate 342 ensures higher relative positional accuracy between the folding door 31 and the bottom support frame 1 each time the column slide bar 341 is inserted into the locking holes 343 for fixing. The correspondence between the locking holes 343 at the bottom of the slide groove 11 and the locking holes 343 on the column locking plate 342 further enhances the accuracy of fixing. This one-to-one correspondence avoids installation difficulties or insecure fixing due to mismatched locking hole positions.
[0046] The rear of the vehicle body 01, furthest from the front, is the rear end. In an optional embodiment, a folding ladder 4 is provided at the rear. The folding ladder 4 can be folded and stored inside the bottom support frame 1. Optionally, the length of the folding ladder 4 is 3 meters. The folding ladder 4 can be stored inside the bottom support frame 1 after folding, which makes full use of the space at the rear of the vehicle, avoiding the ladder occupying extra space. This makes the spatial layout of the vehicle more reasonable during transportation, improves the vehicle's cargo capacity, and also reduces the risk of damage to the ladder caused by external objects colliding with it during vehicle operation, thus helping to extend the ladder's service life.
[0047] In a preferred embodiment, the folding ladder 4 has at least one roller 41 installed at its bottom, and a baffle 42 is provided at the end of the bottom support frame 1 to intercept the roller 41. The roller 41 installed at the bottom of the folding ladder 4 makes it easier to move when unfolding or folding the ladder. When the ladder needs to be unfolded, it is pushed through the roller 41 to smoothly move the ladder out of the bottom support frame 1. When folding the ladder, the roller 41 also helps the ladder to return to its position in the bottom support frame 1 more accurately. The baffle 42 at the end of the bottom support frame 1 is used to intercept the roller 41, which can effectively prevent the ladder from overstretching or falling out of the bottom support frame 1 during unfolding. At the same time, during vehicle transportation, the baffle 42 can prevent the roller 41 from rolling, thereby preventing the ladder from shifting within the bottom support frame 1.
[0048] Optionally, the folding ladder 4 is evenly divided into three parts. The folding ladder 4 can be switched between a folded state and an unfolded state. When folded, the two side sections of the folding ladder 4 are folded and stored in the middle section. The folding ladder 4 is evenly divided into three parts, and the two side sections can be folded and stored in the middle section. In the folded state, the overall shape of the folding ladder 4 is more compact, reducing the space occupied when stored in the bottom support frame 1. Preferably, a folding ladder storage door 5 is provided at the end of the bottom support frame 1 away from the front of the vehicle, and a folding ladder storage door lock 51 is provided on the folding ladder storage door 5. The folding ladder storage door 5 protects the folding ladder 4 placed in the bottom support frame 1, effectively preventing dust, rainwater, etc., from entering the bottom support frame 1 and contacting the folding ladder 4. If the storage door suddenly opens while driving, the folding ladder 4 may slip, posing a serious safety threat to other vehicles and pedestrians on the road. The folding ladder storage door lock 51 ensures that the folding ladder storage door 5 will not open accidentally while the vehicle is in motion.
[0049] The implementation principle of this application embodiment is as follows: When transporting ordinary goods, the trough 3 is in an unfolded state, the goods are loaded on the vehicle floor 2, and the goods are located inside the trough 3. When transporting large goods, the trough 3 is switched to a folded state, so that the folded trough 3 is close to the front of the vehicle, leaving sufficient space for the vehicle body 01 part, and the cargo van is switched to a flatbed van, providing more transportation opportunities for the vehicle. This allows the vehicle to change its own type by changing the state of the trough 3 when facing different goods, and adapt to the transportation of various goods.
[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
