Description

Technical Field

[0001] The present invention relates to the technical field of mechanical manufacturing and vehicle-mounted cargo storage devices, and in particular to a vehicle-mounted cargo storage device and a method for using the same. Background Art

[0002] At present, in the transportation system, in order to ensure the safety of goods during transportation, they need to be stacked, packaged and protected in advance, which generally requires a large amount of foam boards, plastic films and plastic tapes, resulting in a large amount of discarded packaging materials, causing serious waste and environmental pollution. On the other hand, after packaging, it is difficult to easily remove the goods inside the package, which causes the problem of inflexible cargo distribution during cargo transportation and increases the workload for loading workers. On the other hand, for functional vehicles, such as fire equipment vehicles, mobile vending vehicles, mobile dining vehicles, express delivery vehicles, etc., the stored goods often need to be taken out quickly and stored at any time, but due to the maneuvering and bumpy characteristics of the vehicles, the goods need to be reliably fixed, which causes a contradiction between the flexibility and stability of the goods. This shows the important role of cargo storage cabinets and locking mechanisms in the road transportation process.

[0003] How to use a vehicle-mounted cargo storage device to quickly take out the goods when needed and quickly and reliably lock the goods when stored is a major problem in the road transport industry. In the existing technology, open trucks usually use external straps, which are difficult to tie, and the locking effect is determined by human operation, which is very random; box trucks usually use closed cargo compartments, which ensure safety on the road, but lack protection for the internal goods and the ability to classify and distribute them; multi-functional fire equipment transport vehicles usually have customized shelves, but still use the locking structure of traditional straps, which has poor flexibility; vehicle-mounted containers often use drawer-type and flip-type cargo box designs, which can only realize the function of storage and cannot pull out the cargo box to meet the needs of the vehicle. The demand for use under the following circumstances; Patent CN202220385002.7 discloses a cargo box locking mechanism and a vehicle, which locks the cargo box by rotating the locking frame. Although the cargo box is locked, the flexibility of the cargo is not high and the locking action is relatively complicated; Patent CN201822030774.5 discloses a hidden cargo box locking mechanism and a truck with the device. The device locks the cargo box by a lock tongue. Although the locking degree of the cargo box can be adjusted, the locking action is complicated and the adjustment method is complicated, which is not conducive to the needs of speed and flexibility.

[0004] In summary, there is a need for a vehicle-mounted cargo storage device that is highly flexible, highly reliable, and extremely easy to operate. Summary of the Invention

[0010] The cargo box is inserted into the vehicle-mounted smooth cargo box cabinet, and the second roller is sunk into the groove to achieve locking.

[0011] Preferably, the second rollers include three pairs, one pair of which is located at the end of the pressure rod, and the pair of second rollers located at the end of the pressure rod are unlocking rollers.

[0012] Preferably, the grooves include two pairs, and the two pairs of grooves correspond to the two pairs of second rollers located in the middle part of the pressure rod.

[0013] Preferably, when the box body is inserted into a unit of the vehicle-mounted fluid cargo box cabinet, the second roller sinks into the groove.

[0014] Preferably, when the second roller sinks into the groove, the pressure rod presses on the side slide rail.

[0015] Preferably, when the goods need to be taken out, a person or a machine presses the unlocking roller of the locking mechanism to unlock it, and pulls the cargo box outward through the front pull ring until the on-board fluent cargo box cabinet is completely pulled out.

[0016] Preferably, the hinge is fixedly connected to the frame, the hinge is hinged to the connecting rod, and the connecting rod is hinged to the pressure rod.

[0017] Preferably, both ends of the synchronization plate are connected to pressure rods respectively.

[0018] Preferably, when the unlocking roller is pressed, the second roller in the groove rises from the groove.

[0019] According to another aspect of the present invention, a vehicle-mounted cargo storage device and a method for using the same are provided, comprising the following steps: Step 1: When a cargo box needs to be stored, the cargo box is aligned with the entrance position of the vehicle-mounted fluent cargo box cabinet at the storage position by a person or a machine, and the cargo box is pushed inward; when the cargo box reaches the designated position, the second roller sinks into the groove of the cargo box side panel slide rail, and the pressure rod of the locking mechanism automatically falls to lock the cargo box.

[0020] Step 2: When the goods need to be taken out, a person or a machine presses the unlocking roller in the second roller of the locking mechanism to unlock it, and pulls the cargo box outward through the front pull ring until it is completely pulled out of the vehicle-mounted smooth cargo box cabinet.

[0021] Using the technical solution of the present invention, when storing a cargo box, a person or machine aligns the cargo box with the entrance of the vehicle-mounted fluid container cabinet at the storage location and pushes the cargo box inward. When the cargo box reaches the designated position, the second roller sinks into the groove of the cargo box side panel slide rail, and the pressure rod of the locking mechanism automatically drops, locking the cargo box. When removing the cargo, a person or machine presses the unlocking roller in the locking mechanism's second roller to unlock it, and then pulls the cargo box outward using the front pull ring until it is completely removed from the vehicle-mounted fluid container cabinet. This provides high flexibility, high reliability, and extremely simple operation. BRIEF DESCRIPTION OF THE DRAWINGS

The present invention provides a flexible and stable solution for placing cargo on vehicles for road transportation, fire rescue and mobile delivery vehicles.

[0035] In this embodiment, the vehicle-mounted fluent cargo box cabinet 1 has a frame 1-2, and the frame 1-2 is configured as a plurality of units. Each unit is provided with a fluent bar 1-1, and the fluent bar 1-1 includes a mounting plate 1-1-2 and a first roller 1-1-1. Specifically, the vehicle-mounted fluent cargo box cabinet 1 is composed of a plurality of units. The units can be designed to be of different sizes as needed, and the units can be combined into a variety of vehicle-mounted fluent cargo box cabinet 1 forms as needed. Each unit includes a fluent bar 1-1 and a frame 1-2. The fluent bar 1-1 includes rollers and a mounting plate 1-1-2. The vehicle-mounted fluent cargo box cabinet 1 can meet the requirements of vehicle installation, can carry the cargo box 2, can be installed with the locking mechanism 3, and can constrain the left and right movement of the cargo box 2. The vehicle-mounted fluent cargo box cabinet 1 unit can have a variety of combination forms. The vehicle-mounted fluent cargo box cabinet 1 unit includes a transverse roller and a longitudinal roller to achieve the function of carrying the cargo box 2 and constraining the left and right directions of the cargo box 2.

[0036] In this embodiment, the cargo box 2 is inserted into the unit of the frame 1-2 and has a cargo box 2 body. Side rails 2-2 are provided on both sides of the cargo box 2 body. The side rails 2-2 have grooves 2-4, and a pull ring is provided at one end of the cargo box 2 body. The grooves 2-4 include two pairs, and the two pairs of grooves 2-4 correspond to the two pairs of second rollers 3-1 located in the middle part of the pressure rod 3-2. When the box body is inserted into the unit of the vehicle-mounted fluent cargo box cabinet 1, the second roller 3-1 sinks into the groove 2-4. When the second roller 3-1 sinks into the groove 2-4, the pressure rod 3-2 presses on the side rails 2-2. Specifically, the cargo box 2 is designed according to the unit size, including the cargo box 2 body, side rails, and front pull ring 2-3, and cargo can be placed in the cargo box 2. The cargo box 2 contacts the vehicle-mounted fluent cargo box cabinet 1 and the locking mechanism 3 through the side rails, thereby achieving the locking of the cargo box 2. The form of the cargo box 2 is not limited to a rectangular cargo box 2, and may also be other shapes.

[0037] In this embodiment, the locking mechanism is located within the unit of frame 1-2 and comprises a pair of pressure rods 3-2. Second rollers 3-1 are located within the pressure rods 3-2. These rollers 3-1 comprise three pairs, one of which is located at the ends of the pressure rods 3-2. The second pair of rollers 3-1 located at the ends of the pressure rods 3-2 functions as unlocking rollers. A connecting rod 3-4 is located outside the pressure rods 3-2. A hinge 3-3 is connected to the connecting rod 3-4. A synchronizing plate 3-6 is located at the top end of the pressure rod 3-2. Both ends of the synchronizing plate 3-6 are connected to the pressure rod 3-2. The pressure rod 3-2 is connected to one end of a tension spring 3-5. The other end of the tension spring 3-5 and the hinge 3-3 are both connected to frame 1-2. The hinge 3-3 is fixedly connected to frame 1-2. The hinge 3-3 is hingedly connected to the connecting rod 3-4, which is in turn hingedly connected to the pressure rod 3-2. Specifically, the locking mechanism 3 is a mechanism designed according to the size of the unit and the cargo box 2, and includes a roller, a pressure rod 3-2, a hinge 3-3, a connecting rod 3-4, a tension spring 3-5 and a synchronization plate 3-6. When the cam 2 is in the locked position, the locking mechanism 3 is in the unlocked position and the cam 2 is in the locked position, so that the cam 2 can be locked and the cam 2 can be taken out.

[0038] In this embodiment, the cargo box 2 is inserted into the vehicle-mounted fluent cargo box cabinet 1, and the second roller 3-1 is locked by sinking into the groove 2-4. When the cargo needs to be taken out, a person or a machine presses the unlocking roller of the locking mechanism 3 to unlock it, and pulls the cargo box 2 outward through the front pull ring 2-3 until it is completely pulled out of the vehicle-mounted fluent cargo box cabinet 1. When the unlocking roller is pressed, the second roller 3-1 in the groove 2-4 rises from the groove 2-4. When the cargo box 2 needs to be stored, the cargo box 2 is aligned with the entrance position of the vehicle-mounted fluent cargo box cabinet 1 at the storage position by a person or a machine. During the process of pushing the cargo box 2 inward, the side guide rails of the cargo box 2 press the unlocking roller of the locking mechanism 3 to automatically unlock it. When the cargo box 2 reaches the specified position, the pressure rod 3-2 of the locking mechanism 3 can automatically fall down and lock the cargo box 2 at the same time. When the goods need to be taken out, a person or a machine presses the unlocking roller of the locking mechanism 3 to unlock it, and pulls the cargo box 2 outward through the front pull ring 2-3 until the on-board smooth cargo box cabinet 1 is completely pulled out.

[0039] The present invention addresses the issue of securely securing cargo in a transportation system. It utilizes a reusable, vehicle-mounted design to reliably secure cargo, relying solely on mechanical means and eliminating the need for expensive electronic equipment. This ensures cargo safety during transportation, improves reliability and applicability, mitigates threats to road safety, increases economic efficiency, and protects the environment. The present invention allows for rapid insertion and secure self-locking of the cargo box 2. Furthermore, the box 2 can be quickly unlocked and withdrawn by pressing an unlocking wheel. The box 2 can also be completely removed from the cabinet for use outside the vehicle, enabling flexible access and free delivery of cargo.

[0040] The following are described in detail with reference to the accompanying drawings. Figure 1 As shown, the present invention provides a combination of a vehicle-mounted smooth cargo box cabinet 1, a cargo box 2 and a locking mechanism 3, which mainly includes the vehicle-mounted smooth cargo box cabinet 1, the cargo box 2 and the locking mechanism 3. Figure 1 In the locked state, the vehicle-mounted smooth cargo box cabinet 1 is the main structural component, which includes a smooth bar 1-1 and a frame 1-2. The smooth bar 1-1 includes a first roller 1-1-1 and a mounting plate 1-1-2. The vehicle-mounted smooth cargo box cabinet 1 carries the cargo box 2 by contacting the smooth bar 1-1 with the side slide rails 2-2 of the cargo box 2. The cargo box 2 can carry cargo. The locking mechanism 3 is installed on the vehicle-mounted smooth cargo box cabinet 1 to press the side slide rails 2-2 of the cargo box 2. The vehicle-mounted smooth cargo box cabinet 1 is mainly composed of several units. Each unit can be designed with different sizes according to the size of the cargo. The vehicle-mounted smooth cargo box cabinet 1 composed of the above can have a variety of arrangements. Figure 1 Schematic diagram of a 6×6 unit arrangement.

[0041] like Figure 2As shown, the present invention provides a storage device for cargo suitable for vehicles, which mainly includes a cargo box 2 body, side rails 2-2, and a front pull ring 2-3. The side rails 2-2 and the front pull ring 2-3 are respectively installed on the side and front of the cargo box 2 body. The cargo box 2 body is mainly used to carry cargo, and its shape and size can be changed according to the different cargo and user needs. The side rails 2-2 are provided with grooves 2-4 designed according to the locking mechanism 33. The grooves 2-4 can embed the rollers in the locking mechanism 3 therein to achieve the function of locking the cargo box 2. The front pull ring 2-3 is mainly used for people or machines to pull out the cargo box 2.

[0042] like Figure 3 As shown, the present invention provides a locking mechanism 3 for a cargo box 2, which mainly includes a second roller 3-1, a pressure rod 3-2, a hinge 3-3, a connecting rod 3-4, a tension spring 3-5 and a synchronization plate 3-6. The second roller 3-1 is mainly used to unlock the locking mechanism 3, to roll on the side slide rail 2-2 of the cargo box 2 in the unlocked state, and to fit into the groove 2-4 of the side slide rail 2-2 of the cargo box 2 in the locked state to achieve locking of the cargo box 2. The second roller 3-1, the hinge 3-3 and the tension spring 3-5 can be installed on the pressure rod 3-2. In the locked state, the pressure rod 3-2 contacts the side slide rail 2-2 of the cargo box 2 to press the cargo box 2 downward. The main function of the hinge 3-3 is to achieve rotation, and it is combined with the connecting rod 3-4 to form a parallelogram four-link 3-4 structure. This mechanism can make the pressure rod 3-2 always parallel to the side slide rail 2-2 of the cargo box 2 and the smooth bar 1-1. Tension spring 3-5 is connected to compression rod 3-2 at one end and to frame 1-2 at the other. Together with the four-link structure 3-4, it provides downward pressure on compression rod 3-2. Synchronizing plate 3-6 synchronizes the two clamping devices on either side of container 2, maintaining the same operating angle for simultaneous unlocking and locking, while also improving the overall reliability of the structure.

[0043] like Figure 4 The figure shows a schematic diagram of a vehicle-mounted fluid container 1 and the locking mechanism 3 of the present invention, without a cargo box 2. In this state, the second roller 3-1 on the locking mechanism 3 is in contact with the first roller 1-1-1 on the fluid bar 1-1, and the closest distance between the pressure rod 3-2 and the first roller 1-1-1 on the fluid bar 1-1 is less than the thickness of the side rail 2-2 of the cargo box 2.

[0044] like Figure 5The figure shows a schematic diagram of a unit of the vehicle-mounted fluid container 1 provided by the present invention, the cargo box 2, and the locking mechanism 3 in an unlocked state. In this state, the cargo box 2 may be in the process of being inserted inward or removed outward, and at least one second roller 3-1 of the rollers on the locking mechanism 3 contacts the upper surface of the side rails 2-2 of the cargo box 2. This prevents the rollers on the locking mechanism 3 from being embedded in the grooves 2-4 of the side rails 2-2 of the cargo box 2 during the sliding process, ensuring that the locking state is not entered during the sliding process.

[0045] like Figure 6 The figure shows a schematic diagram of a vehicle-mounted fluid container 1, the cargo box 2, and the locking mechanism 3 in a locked state. In this state, the pressure bar 3-2 of the locking mechanism 3 contacts the upper surface of the side rails 2-2 of the cargo box 2, and the second roller 3-1 of the locking mechanism 3 engages the groove 2-4 of the side rails 2-2 of the cargo box 2. The vertical freedom of the cargo box 2 is constrained by the fluid bar 1-1 and the locking mechanism 3. The left and right freedom of the cargo box 2 is constrained by the transverse rollers of the fluid bar 1-1. Since the rollers on the locking mechanism 3 are embedded in the grooves 2-4 of the side rails 2-2 of the cargo box 2 and in contact with the latter's front and rear side walls, and since the parallelogram four-link 3-4 mechanism composed of the pressure rod 3-2, frame 1-2, connecting rod 3-4 and hinge 3-3 is in the dead point position in the outward withdrawal direction, the pressure rod 3-2 can only move downward, further pressing the cargo box 2. Moreover, since the front limit of the frame 1-2 is in contact with the back of the cargo box 2, the cargo box 2 cannot be pushed forward any further. The joint cooperation of the mechanisms realizes the constraint of the forward and backward push-pull directions of the cargo box 2. Therefore, in the locked state, the six directions of the cargo box 2, including up, down, left, right, front and back, are all in a constrained state, ensuring the safe locking of the cargo box 2. Figure 6 As shown, if, in the locked state, the unlocking roller on the locking mechanism 3 near the front pull ring 2-3 is pressed in the direction of the arrow in the figure, the locking mechanism 3 can be lifted upward by the action of the four-bar linkage 3-4 structure, causing the roller to be slightly higher than the upper surface of the side rail 2-2. While the unlocking roller is still pressed, the front pull ring 2-3 is pulled by a person or a machine, causing the cargo box 2 to be withdrawn a short distance. At this time, the roller is directly above the upper surface of the side rail 2-2. Thereafter, during the outward withdrawal process, even if the roller is not pressed, one of the rollers on the locking mechanism 3 will always be in contact with the upper surface of the side rail 2-2 of the cargo box 2, thereby preventing the locking mechanism 3 from entering the locked state. This allows the cargo box 2 to be unlocked and withdrawn.

[0046] During the entire process described above, the tension spring 3-5 provides driving force to the four-link 3-4 mechanism in the locking mechanism 3 by applying tension between the frame 1-2 and the connecting rod 3-4, forcing the locking mechanism 3 to always have a tendency to lock downward. This tension needs to be overcome when unlocking the cargo box 2. This tension also provides the locking mechanism 3 with the power to press the cargo box 2 downward, thereby achieving reliable mechanical locking.

[0047] Another embodiment of the present invention provides a method for using a vehicle-mounted cargo storage device.

[0048] Step 1: When it is necessary to store the cargo box 2, a person or machine aligns the cargo box 2 with the entrance of the vehicle-mounted fluid container cabinet 1 at the storage position and pushes the cargo box 2 inward. When the cargo box 2 reaches the designated position, the second roller 3-1 sinks into the groove 2-4 of the side panel slide rail of the cargo box 2, and the pressure rod 3-2 of the locking mechanism 3 automatically drops, locking the cargo box 2. Step 2: When it is necessary to remove the cargo, a person or machine presses the unlocking roller in the second roller 3-1 of the locking mechanism 3 to unlock it, and pulls the cargo box 2 outward using the front pull ring 2-3 until it is completely removed from the vehicle-mounted fluid container cabinet 1.

[0049] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when storing the cargo box 2, the cargo box 2 is aligned with the entrance position of the vehicle-mounted fluent cargo box cabinet 1 at the storage position by a person or a machine, and the cargo box 2 is pushed inward. When the cargo box 2 reaches the designated position, the second roller 3-1 is sunk into the groove 2-4 of the side panel slide rail of the cargo box 2, and the pressure rod 3-2 of the locking mechanism 3 automatically drops, locking the cargo box 2. When removing the cargo, the unlocking roller of the second roller 3-1 of the locking mechanism 3 is pressed by a person or a machine to unlock it, and the cargo box 2 is pulled outward through the front pull ring 2-3 until it is completely removed from the vehicle-mounted fluent cargo box cabinet 1. The technical effects of high flexibility, high reliability, and extremely simple operation are achieved.

[0050] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
