Description

Technical Field

[0001] This application relates to the field of transportation technology, and in particular to a rainproof vehicle. Background Technology

[0002] Existing freight transport vehicles are typically equipped with lifting devices and cargo transfer mechanisms, enabling the lifting, transport, and transfer of goods or containers containing goods. However, most cargo containers lack rain protection, making them susceptible to rain damage during transfer, potentially causing the contents to become damp or damaged. Furthermore, the vehicle's original appearance is compromised after the cargo containers are removed; the vehicle's shape differs depending on whether it has cargo containers on it or not. Therefore, a solution is needed to ensure that cargo containers are rainproof during transport while maintaining the vehicle's original characteristics. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a rainproof vehicle that can provide rain protection during the transfer of cargo containers while ensuring the vehicle retains its complete vehicle characteristics.

[0004] A rainproof vehicle according to an embodiment of the present invention is used for transporting cargo containers. The rainproof vehicle includes: a vehicle body, the vehicle body including a placement platform for placing the cargo containers; a translation device including a moving part capable of horizontal movement relative to the vehicle body; a lifting device disposed on the moving part, the lifting device being used to hoist the cargo containers and drive the cargo containers to rise and fall, and the translation device and the lifting device being capable of transferring cargo containers outside the placement platform to the placement platform; and a rain cover disposed on the lifting device, at least a portion of the rain cover covering the cargo containers.

[0005] A rainproof vehicle according to an embodiment of the present invention has at least the following beneficial effects: the translation device and the lifting device can place cargo containers from the ground to the placement platform more quickly and conveniently, or place cargo containers from the placement platform to the ground. When it is necessary to move the cargo containers, the translation device needs to move the lifting device, and the rain cover is connected to the lifting device. When the translation device moves the lifting device, the rain cover will also move with the lifting device. That is, when the lifting device needs to lift the cargo containers, the translation device needs to move the lifting device above the cargo containers first, at which time the rain cover will also move above the cargo containers. In this way, the rain cover can not only protect the cargo containers from rain when the rainproof vehicle is transporting them, but also protect them from rain when the cargo containers are transferred to the placement platform. The rain cover being fixed to the lifting device also allows the rainproof vehicle to have a fixed rain cover, so that the rain cover can be set with the rain cover's unique identification, and the rainproof vehicle has consistent and complete vehicle characteristics regardless of whether there are cargo containers on it, so that the rainproof vehicle has a fixed and standard-compliant identification during transportation.

[0006] According to some embodiments of the present invention, the moving direction of the moving part overlaps with the driving direction of the rainproof vehicle.

[0007] According to some embodiments of the present invention, the moving part can move to a first limit position and a second limit position. When the moving part moves to the first limit position, the vertical projection of the cargo container on the lifting device is on the placement platform; when the moving part moves to the second limit position, the vertical projection of the cargo container on the lifting device is outside the placement platform.

[0008] According to some embodiments of the present invention, the lifting device includes a lifting frame and a second drive assembly. The lifting frame is slidably disposed on the moving part. The second drive assembly is used to drive the lifting frame to slide vertically relative to the moving part. The rain cover is fixed on the lifting frame. The lifting frame is used to connect with the cargo container.

[0009] According to some embodiments of the present invention, the lifting frame includes a top frame and a connecting rod. The connecting rod is disposed on the side of the top frame near the bottom surface. The rain cover is fixedly connected to the top frame. A hook is provided at the end of the connecting rod away from the top frame. The hook is used to connect the cargo container.

[0010] According to some embodiments of the present invention, the lifting device includes a second drive assembly, a top bracket, and a chain. The top bracket is fixedly mounted on the moving part, and the chain is mounted on the top bracket. The second drive assembly is used to retract and extend the chain.

[0011] According to some embodiments of the present invention, the rain cover includes a top surface and multiple side surfaces, the top surface is connected to the top of the side surfaces, the multiple side surfaces together surround the top surface, and adjacent two side surfaces are detachably connected.

[0012] According to some embodiments of the present invention, a connector is provided at the bottom of the side, and the moving part can move to the locking position. When the moving part moves to the locking position, the lifting device corresponds to the position of the cargo container on the placement platform; when the moving part moves to the locking position, the connector is detachably connected to the placement platform.

[0013] According to some embodiments of this utility model, the side has a shielding state and a retracted state. When the side is in the shielding state, the side and the top surface together enclose a cavity for accommodating a cargo container. When the side is in the retracted state, two adjacent sides are separated from each other, and the side releases its shielding of the side of the cavity. The rainproof vehicle also includes a retracting device, which can retract the side to keep the side in the retracted state.

[0014] According to some embodiments of the present invention, the top surface and the plurality of side surfaces enclose a cavity, the moving part and the lifting device are both disposed in the cavity, the opening of the cavity is at the bottom of the cavity, and the opening allows the cargo container to enter and exit the cavity.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0033] Reference Figure 1 , Figure 2 and Figure 3 A rainproof vehicle according to a first aspect of this utility model is used to transport cargo containers 5. The rainproof vehicle includes: a vehicle body 1, a translation device 2, a lifting device 3, and a rain cover 4. The vehicle body 1 includes a placement platform 11 for placing the cargo containers 5. The translation device 2 includes a moving part 21 and a fixed part. The moving part 21 is fixedly connected to the vehicle body 1 and is slidably disposed relative to the fixed part. The lifting device 3 is disposed on the moving part 21 and is used to lift the cargo containers 5 and drive the cargo containers 5 to rise and fall. The rain cover 4 is disposed on the lifting device 3 and is used to protect the cargo containers 5 from rain, covering at least the top of the cargo containers 5. When it is necessary to transfer the cargo containers 5 to the rainproof vehicle, i.e., the placement platform 11, the lifting device 3 is first moved above the cargo containers 5 on the ground by the translation device 2, at which time the rain cover 4 can protect the cargo containers 5 from rain. It is important to note that the cargo container 5 on the ground refers not only to the cargo container 5 placed on the ground, but also includes cargo containers 5 on other transport vehicles and cargo containers 5 in other locations that need to be transferred to the placement platform 11. When the lifting device 3 moves directly above the cargo container 5 on the ground, it raises the cargo container 5 so that its bottom is higher than the placement platform 11. Then, the translation device 2 moves the cargo container 5 from the lifting device 3 to above the placement platform 11, and the lifting device 3 places the cargo container 5 on the placement platform 11. Raising the bottom of the cargo container 5 above the placement platform 11 by the lifting device 3 avoids interference between the cargo container 5 and the vehicle body 1 during the translation process.

[0034] In existing technologies, to improve the efficiency of logistics transportation, full-box or full-cage methods are used for transshipment, which greatly reduces the time for goods transportation. However, using full boxes or full cages as cargo containers increases volume and weight, affecting loading and unloading. For example, setting up a rainproof compartment on a cart not only increases vehicle costs but also makes it easy for cargo containers to interfere with the compartment, making it difficult to place them inside. To reduce costs and facilitate placing cargo containers on the cart, a tarpaulin is usually used to cover them after placement. However, this not only fails to protect the cargo containers from rain during transportation but also prevents the display of fixed identification on the delivery vehicle. Under current policies, vehicles are required to affix reflective strips to the sides and lower rear of the cargo compartment and spray-paint a license plate three times larger than the standard license plate at a suitable location on the rear of the cargo box to ensure visibility and safety on the road. This means a fixed license plate needs to be sprayed onto the tarpaulin. Each vehicle has a fixed license plate, so each vehicle must have its own specific rain cover. However, with existing technology, not only will the marking position be inaccurate and the vehicle will not be able to maintain its complete vehicle characteristics, but it is also necessary to distinguish the rain cover of each vehicle.

[0035] In the logistics industry, when goods are transported in a distributed manner, multiple smaller transport vehicles are typically used to distribute the goods from a larger truck. The larger truck has a rainproof cargo box, while the smaller transport vehicles can be rainproof wagons. When the cargo container 5 is transferred from the larger truck to the rainproof wagon, if the rain cover 4 cannot move with the lifting device 3, the cargo container 5 will be exposed to rain while positioned between the rainproof wagon and the truck. Therefore, the rain cover 4 is installed on the lifting device 3 to prevent the cargo container 5 from getting wet during the transfer.

[0036] The lifting device 3 raises the cargo container 5 on the placement platform 11, separating the bottom of the cargo container 5 from the placement platform 11. Separating the bottom of the cargo container 5 from the placement platform 11 prevents friction between the cargo container 5 and the placement platform 11 during translation. The translation device 2 then moves the cargo container 5 from the lifting device 3 to the outside of the placement platform 11. Finally, the lifting device 3 places the cargo container 5 on the ground.

[0037] After the rain cover 4 is fixedly mounted on the lifting device 3, the rain cover 4 can be used to affix the vehicle's unique markings, such as the vehicle's number and license plate. Furthermore, because the markings are on the rain cover 4, the rainproof vehicle retains its complete vehicle characteristics even when no cargo container 5 is placed on the placement platform 11. In the prior art, a rainproof film is typically applied to the cargo container 5 to protect it from rain, which not only prevents the affixing of vehicle markings but also fails to maintain the vehicle's complete characteristics when the cargo container 5 is not placed on the rainproof vehicle.

[0038] According to some embodiments of this utility model, the fixed part includes a track 22, the movable part 21 is slidably disposed on the track 22, and the translation device 2 further includes a first driving component, which is used to drive the movable part 21 to slide along the track 22. The moving direction of the movable part 21 overlaps with the driving direction of the rainproof vehicle. The track 22 can extend in multiple directions, for example, it can extend laterally. When the track 22 extends laterally, the lifting device 3 can be translated to the left or right side of the vehicle body 1. At this time, the cargo container 5 on the left or right side of the vehicle body 1 can be transferred to the placement platform 11 by the lifting device 3 and the translation device 2. However, when the weight of the cargo container 5 is too large, it is easy to cause the vehicle body 1 to tip over. Therefore, as a preferred option, the extension direction of the track 22 is set to the driving direction of the rainproof vehicle, so that the cargo container 5 behind the vehicle body 1 can be transferred to the placement platform 11, thus preventing the vehicle body 1 from tipping over. The first driving component can be a hydraulic rod, which drives the sliding of the movable part 21 by extending and retracting the hydraulic rod. On the other hand, the first drive assembly may also include a motor, a transmission component and a roller, wherein the motor drives the roller to rotate through the transmission component, thereby causing the moving part 21 to slide on the track 22.

[0039] According to some embodiments of this utility model, the moving part 21 can move to a first limit position and a second limit position. When the moving part 21 moves to the first limit position, the vertical projection of the cargo container 5 on the lifting device 3 is on the placement platform 11; when the moving part 21 moves to the second limit position, the vertical projection of the cargo container 5 on the lifting device 3 is outside the placement platform 11. By setting the first limit position and the second limit position, the cargo container 5 can be accurately transferred to the placement platform 11. The first limit position ensures that when the cargo container 5 is lowered, it can be completely placed on the placement platform 11, thereby preventing part of the cargo container 5 from being suspended outside the placement platform 11. The second limit position prevents the moving part 21 from detaching from the fixed part and also prevents the torque generated when the cargo container 5 is lifted from a large distance due to the large distance the moving part 21 moves. The first limit position of the moving part 21 is referenced to... Figure 1 , Figure 2 and Figure 3 The second extreme position of the moving part 21 is referenced. Figure 4 , Figure 5 and Figure 6 .

[0040] The specific implementation method is as follows: a first limiting block 23 and a second limiting block 24 are set on the track 22. The first limiting block 23 and the second limiting block 24 are set at intervals along the moving direction of the moving part 21. The moving part 21 is set between the first limiting block 23 and the second limiting block 24. When the moving part 21 abuts against the first limiting block 23, the vertical projection of the cargo container 5 on the lifting device 3 is on the placement platform 11. When the moving part 21 abuts against the second limiting block 24, the vertical projection of the cargo container 5 on the lifting device 3 is outside the placement platform 11.

[0041] The rainproof vehicle has multiple states. The translation device 2 includes a first state and a second state, and the lifting device 3 also includes a first state and a second state. The first state of the translation device 2 is when the moving part 21 moves to a first limit position, and the second state is when the moving part 21 moves to a second limit position. When the translation device 2 is in the second state, the lifting device 3 can switch between the first and second states. When the lifting device 3 is in the first state, it rises to lift the cargo container 5, with the bottom of the cargo container 5 higher than the placement platform 11. When the lifting device 3 is in the second state, it descends, at which point it can connect with the cargo container 5 on the ground. The first state of the lifting device 3 is described below. Figure 4 , Figure 5 and Figure 6 The second state reference of lifting device 3 Figure 7 , Figure 8 and Figure 9 .

[0042] According to some embodiments of this utility model, refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9The lifting device 3 includes a lifting frame 31 and a second drive assembly. The lifting frame 31 is slidably mounted on the moving part 21. The second drive assembly drives the lifting frame 31 to slide vertically relative to the moving part 21. A rain cover 4 is fixedly mounted on the lifting frame 31. The lifting frame 31 has a connecting end for connecting to the cargo container 5. The second drive assembly drives the lifting frame 31 to slide relative to the moving part 21. When the cargo container 5 on the ground needs to be transferred, the second drive assembly first lowers the height of the lifting frame 31. After the height of the lifting frame 31 is lowered, the connecting end on the lifting frame 31 is fixedly connected to the cargo container 5. A connection structure for fixing to the connecting end can be provided at any position on the cargo container 5, and the connecting end can also support the cargo container 5 from the bottom.

[0043] According to some embodiments of this utility model, the lifting frame 31 includes a top frame 311 and a connecting rod 312. The connecting rod 312 is disposed on the side of the top frame 311 near the bottom surface. The rain cover 4 is fixedly connected to the top frame 311, and the connecting end is disposed at the end of the connecting rod 312 away from the top frame 311. In order to more conveniently fix the cargo container 5 to the lifting frame 31, the top frame 311 and the connecting rod 312 are provided. The connection between the top frame 311 and the rain cover 4 allows the rain cover 4 to cover the cargo container 5 from the top. The connecting rod 312 makes it easier to connect the connecting end to the cargo container 5. For example, when the cargo container 5 is misaligned, the connecting rod 312 can correct the deviation, so that the connecting end can be connected to the connecting position of the cargo container 5.

[0044] According to some embodiments of this utility model, refer to Figure 10 and Figure 11 The lifting device 3 includes a second drive assembly, a top support 32, and a chain 33. The top support 32 is fixedly mounted on the moving part 21, and the chain 33 is mounted on the top support 32. The second drive assembly is used to retract and extend the chain 33. The lifting device 3 is relatively complex to operate, hence the top support 32 and chain 33 are used. The top support 32 supports the rain cover 4, providing rain protection for the cargo container 5. When lifting the cargo container 5, the chain 33 is first released, and after it is attached to the cargo container 5, it is retracted, causing the cargo container 5 to be lifted. Alternatively, a telescopic rod can be used to replace the chain 33, and the cargo container 5 can be lifted by extending or retracting the rod. The chain 33 can be made of various soft lifting materials, such as ropes and chains.

[0045] According to some embodiments of this utility model, the rain cover 4 includes a top surface 41 and multiple side surfaces 42. The top surface 41 is connected to the top of the side surfaces 42, and the multiple side surfaces 42 surround the top surface 41. Adjacent side surfaces 42 are detachably connected. For the rain cover 4, it is necessary to protect the cargo container 5 from rain not only on the top surface 41 but also on the side surfaces 42. The most commonly used cargo container 5 is a cuboid, which, for example, includes a top surface 41 and four side surfaces 42. During the transfer of the cargo container 5, adjacent side surfaces 42 can be separated to avoid interference between the side surfaces 42 and the cargo container 5. For example, after separating adjacent side surfaces 42, the side surfaces 42 can be folded onto the top surface 41, making the transfer of the cargo container 5 more convenient. The detachable connection between the side surfaces 42 can be achieved using snaps, Velcro, or other methods.

[0046] According to some embodiments of this utility model, a connector 43 is provided at the bottom end of the side 42, and the moving part 21 can move to the locking position. When the moving part 21 moves to the locking position, the lifting device 3 corresponds to the position of the cargo container 5 on the placement platform 11. When the moving part 21 moves to the locking position, the connector 43 is detachably connected to the placement platform 11. Firstly, in order to prevent the moving part 21 from sliding relative to the fixed part during the movement of the trolley, a locking position is provided to fix the moving part 21 to the fixed part in the locking position, thereby preventing the moving part 21 from moving due to the inertia of the vehicle. Especially when no cargo container 5 is placed on the placement platform 11, the movement of the moving part 21 is unobstructed. At this time, the moving part 21 is very likely to move when the rainproof vehicle starts or brakes. Therefore, a locking position is provided to lock the moving part 21. On the other hand, rainy weather is usually accompanied by strong winds, and airflow can also form during vehicle movement due to various reasons. Therefore, the rain cover 4 is easily blown up or even torn by the airflow, especially when no cargo container 5 is placed on the placement platform 11, the rain cover 4 is more affected. Therefore, a connector 43 is provided to fix the bottom end of the side 42 to the placement platform 11 during the movement of the rainproof vehicle, thereby preventing the airflow from blowing the rain cover 4 up. The connector 43 can be a hook or Velcro device. The locking position is the same as the first limit position of the movement of the moving part 21, which can be referred to. Figure 1 .

[0047] According to some embodiments of this utility model, a retractable device is also included, which can retract the side 42 when it is separated between two adjacent side surfaces 42. When transferring the cargo container 5 to the placement platform 11 or transferring the cargo container 5 from the placement platform 11, the side surface 42 of the rain cover 4 may affect the movement of the cargo container 5, or even damage the cargo container 5 and the rain cover 4. Therefore, the side surface 42 is retracted during the transfer of the cargo container 5. At the same time, when unloading the cargo in the cargo container 5, unloading may also be done on the side surface. Retracting the side surface with the retractable device can make unloading more convenient. The side surface 42 can be retracted in several ways. First, it can be folded over to the top of the rain cover 4. Velcro or buckles can also be used as retractable devices to fix the side surface 42 to the top surface 41. Second, it can be folded and fixed. Third, a roll can be used as a retractable device, and the side surface 42 can be wound into the roll.

[0048] According to some embodiments of this utility model, a cavity is formed by a top surface 41 and multiple side surfaces 42. A moving part 21 and a lifting device 3 are both disposed within the cavity. The lifting device 3 drives the cargo container 5 to enter and exit the cavity through its opening, which is located at the bottom of the cavity. By forming the cavity with the top surface 41 and side surfaces 42, the cargo container 5 can be more comprehensively protected from rain. When the lifting device 3 includes a lifting frame 31 and a second driving assembly, when the translation device 2 moves to the second state, the cargo container 5 is positioned directly below the opening of the cavity. Then, the lifting device 3 switches from the first state to the second state, at which point the entire cavity moves downwards and covers the outside of the cargo container 5, allowing the cargo container 5 to enter the cavity through the opening at the bottom. When the lifting device 3 includes a top support 32 and a chain 33, when the translation device 2 moves to the second state, the opening of the corresponding chamber of the cargo container 5 is located directly below the chamber. Then, the lifting device 3 switches from the first state to the second state, and in the second state, the cargo container 5 is fixed on the chain 33. Then, the chain 33 is retracted to switch the lifting device 3 from the second state to the first state. When the lifting device 3 switches from the second state to the first state, the cargo container 5 rises and enters the interior of the chamber from the opening at the bottom of the chamber.

[0049] The exterior of cargo container 5 is usually covered with a disposable plastic film for some degree of rain protection. However, in order to reduce costs, the disposable plastic film has poor rain protection and cannot provide rain protection for a long time. It is also easy to be damaged. Therefore, rain protection equipment is required during transportation.

[0050] In existing technologies, there are many types of rainproof fabric materials, each with its unique performance characteristics and applicable scenarios. Choosing the right rainproof fabric material is crucial for ensuring the safety of items, extending their lifespan, and adapting to different environmental conditions. Below is a detailed introduction to several common rainproof fabric materials and a comparison of their effects:

[0051] First, polyethylene (PE) tarpaulin is widely popular for its lightweight, softness, and excellent waterproof performance. This material is typically made of high-density polyethylene, which has good tensile strength and abrasion resistance, enabling it to withstand friction and pulling during daily use. PE tarpaulin also has excellent weather resistance, maintaining its original physical properties even after prolonged exposure to sunlight and rain.

[0052] Next, polyvinyl chloride (PVC) tarpaulin is known for its durability and waterproof properties. Through a coating process, PVC material is covered with a tough layer of PVC resin. This protective film not only enhances the material's waterproof ability but also improves its abrasion resistance and chemical corrosion resistance. PVC tarpaulin can withstand harsh weather conditions such as strong winds, heavy rain, and even some acidic substances. However, PVC tarpaulin is relatively heavy and less breathable than other materials, which limits its application to some extent.

[0053] Polyethylene vinyl acetate (PEVA) tarpaulin is an environmentally friendly material that combines the flexibility of polyethylene with the waterproof properties of vinyl acetate. PEVA tarpaulin is typically manufactured using a hot-melt adhesive process, resulting in a smooth surface and excellent waterproof performance. It not only effectively prevents rainwater penetration but also has good corrosion resistance, making it suitable for harsh environments such as acid rain or salt spray. PEVA tarpaulin also has relatively good breathability.

[0054] Polyester tarpaulin is favored for its durability and lightweight properties. This material is typically coated with a waterproof material, such as polyurethane or PVC, to enhance its waterproof performance. Polyester tarpaulin is not only resistant to high and low temperatures, but also maintains good physical properties under various climatic conditions.

[0055] Finally, waterproof fabrics coated with polyurethane (PU) or polytetrafluoroethylene (PTFE, such as Gore-Tex) are a high-end choice for outdoor sports and professional fields. These fabrics typically use nylon or polyester fibers as a base material, with one or more layers of waterproof and breathable PU or PTFE membrane coated on the surface.

[0056] When comparing the effects, we can see that although all these rainproof fabric materials perform well in terms of waterproofing, there are significant differences in breathability, durability, weight, and environmental friendliness. For example, PEVA and polyester rainproof fabrics excel in breathability and environmental friendliness; PVC rainproof fabrics are waterproof and durable, but have poor breathability and are not as environmentally friendly as other materials; while high-end coated fabrics such as Gore-Tex perform well in waterproofing, breathability, and durability, but are relatively expensive.

[0057] On the other hand, rain covers can be made of flexible waterproof fabric or multiple rigid panels (such as waterproof plastic panels) spliced ​​together.

[0058] In the description of this utility model, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
