Description

Technical Field

[0001] This utility model belongs to the technical field of vehicle guardrail devices, and specifically relates to a vehicle guardrail device and a vehicle. Background Technology

[0002] In the rapid development of modern society, technological levels are constantly rising, and at the same time, various emergency scenarios are becoming increasingly complex and changeable, placing more stringent demands on the efficiency and quality of emergency rescue work. As a key piece of equipment in the emergency rescue system, the design and optimization of the emergency support vehicle are of paramount importance.

[0003] Traditional emergency response vehicles typically load rescue kits onto the vehicle's trunk and then secure them with screws or straps. While this method meets basic transportation needs to some extent, its drawbacks are becoming increasingly apparent as rescue missions become more demanding and diverse.

[0004] Currently, some fire and rescue equipment is being loaded using flight cases. However, when setting off for a rescue operation, rescuers still need to place each flight case individually in the vehicle's trunk and secure them with ropes or straps. This method of securing the cases has several drawbacks: Firstly, carrying each case individually greatly increases the workload for rescuers. In emergency rescue scenarios where time is of the essence, this method severely reduces rescue efficiency and may lead to missing the optimal rescue opportunity. Secondly, the securing methods such as screws, straps, and ropes are relatively insecure. During vehicle movement, especially when encountering bumpy roads or emergency braking, the cases are prone to displacement or even tipping over. This could not only damage the rescue equipment inside but also interfere with the vehicle's normal operation, creating safety hazards and significantly affecting the reliability and effectiveness of emergency rescue.

[0005] In summary, there is significant room for improvement in the way existing emergency support vehicles mount and secure their containers. There is an urgent need to develop an emergency support vehicle design that allows for quick assembly and disassembly of the containers and the vehicle, while ensuring a secure and reliable fixation, in order to better meet the needs of modern fire rescue and other emergency scenarios.

[0039] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0040] The core of this utility model is to provide a vehicle guardrail device and a vehicle, which can realize quick assembly and disassembly of the packaging box and the vehicle guardrail device, and the fixation is firm and reliable.

[0041] To enable those skilled in the art to better understand the technical solutions provided by this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] For details, please refer to Figures 1-10 This utility model provides a vehicle guardrail device for transporting a packaging box 200. The packaging box 200 can be a rescue box required for emergency support vehicles, and can also be used on different types of vehicles according to other needs. The bottom front and rear sides of the packaging box 200 are respectively provided with limit slots and a first locking part 220.

[0043] The vehicle guardrail device 100 provided by this utility model mainly includes a guardrail main frame 111.

[0044] The space inside the main frame 111 of the guardrail is used to accommodate the packaging box 200. The main frame 111 of the guardrail may include multiple beams, multiple posts, and connectors that connect the beams and posts, forming a rectangular frame structure.

[0045] At the bottom of the main frame 111 of the guardrail, a limit block 120 is provided at the first position near the loading port. The limit block 120 is used to engage with the limit slot of the packaging box 200, which can restrict the packaging box 200 from moving backward and left and right in the first position.

[0046] The bottom of the main frame 111 of the guardrail is provided with a second snap-fit ​​part 130 at a second position away from the loading port. The second snap-fit ​​part 130 is used to snap-fit ​​with the first snap-fit ​​part 220 of the packaging box 200, which can restrict the packaging box 200 from moving upward and forward in the second position.

[0047] The aforementioned limiting block 120 and the second locking part 130 form a holistic stable limiting in six directions: front and back, left and right, and up and down. This effectively prevents the packaging box 200 from shaking or shifting within the main frame 111 of the guardrail, ensuring the safety and stability of the packaging box 200 during transportation or storage, and reducing the risk of collisions and damages that may result from the movement of the packaging box 200.

[0048] A limit bar 140 is detachably installed at the top of the main frame 111 of the guardrail. The limit bar 140 is used to restrict the upward movement of the packaging box 200. The design of the detachable limit bar 140 at the top of the main frame 111 of the guardrail makes the unloading operation simpler and faster.

[0049] The vehicle guardrail device 100 provided in this solution, when loading and securing the packaging box 200, pushes the packaging box 200 inward from the loading port of the guardrail main frame 111, causing the first locking part 220 of the packaging box 200 to engage with the second locking part 130 of the guardrail main frame 111. This restricts the packaging box 200 from moving upward and forward in a second position. Then, the packaging box 200 is lifted (the lifting method can be achieved by providing a handle 210 on the packaging box 200) so that its limiting slot engages with the limiting block 120 of the guardrail main frame 111, thereby restricting the packaging box 200 from moving backward and left and right in a first position. Finally, the limiting rod 140 is installed to restrict the packaging box 200 from moving upward, ultimately achieving rapid securing of the packaging box 200. When unloading the packaging box 200, there is no need to disassemble the entire main frame 111 of the guardrail. Simply remove the limiting rod 140 first, then lift the packaging box 200 to disengage it from the limiting block 120, and then pull the packaging box 200 backward to release it from the second locking part 130. This will easily complete the unloading process, greatly improving unloading efficiency, saving manpower and time costs, and enhancing the smoothness of the overall operation.

[0050] The above setup allows for quick assembly and disassembly of the packaging box 200 and the vehicle guardrail device 100, while ensuring a secure and reliable fixation.

[0051] Furthermore, the limiting blocks, locking parts, and limiting rods used in the vehicle guardrail device are all common mechanical structural components, resulting in low manufacturing costs, simple processing techniques, and convenient installation and operation. The limiting structure of this vehicle guardrail device is rationally designed and can adapt to various types of packaging boxes 200 with corresponding limiting slots and grooves, thus having a wide range of applications. It can meet the fixing and limiting needs of boxes of different specifications and sizes, and is suitable for various logistics transportation and warehousing scenarios, demonstrating high practical value and significant potential for promotion.

[0052] This solution also includes a rear-hinged door 112 and a locking mechanism. The rear-hinged door 112 is rotatably mounted at the loading port of the main frame 111 of the guardrail. The locking mechanism is used to restrict the relative movement of the rear-hinged door 112 and the main frame 111 of the guardrail. During loading, the rear-hinged door 112 is opened to allow the packaging box 200 to smoothly enter the main frame 111 of the guardrail from the loading port. After the packaging box 200 is securely fixed, the rear-hinged door 112 is locked by the locking mechanism.

[0053] In a specific embodiment, such as Figure 4 and Figure 5As shown, the second locking part 130 is the second locking slot, and the first locking part 220 is the first locking slot. The opening of the second locking slot faces directly forward, and the width of the first locking slot is greater than the width of the second locking slot. The locking slots on the main frame of the guardrail 111 and the packaging box 200 interlock, which can restrict the upward and forward movement of the packaging box 200 in the second position.

[0054] In a specific embodiment, the main frame 111 of the guardrail and the limiting rod 140 are connected by multiple wing screws. The wing screw head's wing-shaped design increases the lateral force-bearing surface, facilitating hand-tightening and greatly improving efficiency during hand-tightening operations.

[0055] like Figure 5 As shown, there are two limit blocks 120 and one second locking part 130.

[0056] To ensure stable installation and positioning, two limiting blocks 120 are respectively set on the left and right sides of the main frame 111 of the guardrail near the loading port, and the second snap-fit ​​part 130 is set in the middle position on the side of the main frame 111 away from the loading port.

[0057] In the existing technology, some multi-functional vehicles can directly switch between cargo vans and support vehicles. When switching to a support vehicle, the side guardrails 113 on both sides need to be removed, while when switching to a cargo van, the side guardrails 113 need to be installed.

[0058] To avoid wasting time installing and removing the side railings 113, several side railings 113 are detachably installed on the side frames of the main railing frame 111. Specifically, the main railing frame 111 is provided with a U-shaped bending block 114, which has a pin hole 115. The end of the side railing 113 is provided with a pin mechanism, and the pin 1131 of the pin mechanism is used to mate with the pin hole 115. Compared with bolt connection, this facilitates quick assembly and disassembly.

[0059] The U-shaped bending block 114 has a U-shaped cross-section and a U-shaped longitudinal section. The U-shaped bending block 114 has openings at the top and along the length of the side guardrail 113, and the pin opening 115 is located on the side opposite to the length of the side guardrail 113. This design improves the reliability of the U-shaped bending block 114, restricting the left-right and downward movement of the side guardrail 113, while the pin 1131 and pin opening 115 cooperate to restrict upward movement.

[0060] In a specific embodiment, the latch mechanism includes a lock body, a latch 1131, a latch lug 1132, and a spring.

[0061] The lock body is the basic component of the entire latch mechanism, providing a location for the installation and support of other components. Specifically, the lock body is installed on the side guardrail 113.

[0062] The bolt 1131 is installed in the lock body, and the bolt lug 1132 is set on the bolt 1131. The lock body is provided with a first clearance groove for avoiding the bolt lug 1132. The bolt lug 1132 is used to drive the bolt 1131 to make linear movement in the lock body.

[0063] A spring is positioned between the pin 1131 and the lock body. One end of the spring is connected to a fixed point inside the pin, while the other end is positioned on the pin 1131.

[0064] The spring can push the pin 1131 out of the lock body without external force. When the pin 1131 extends out of the lock body and inserts into the corresponding pin hole 115, it can lock the side rail 113 onto the main frame 111 of the railing. When unlocking is required, the pin lug 1132 is pulled by external force to overcome the spring force and push the pin 1131 inward, keeping the pin 1131 in the unlocked state, thereby removing the side rail 113 from the main frame 111 of the railing. When the external force is removed, the spring force pushes the pin 1131 back to its original position and out of the lock body, realizing the automatic locking function.

[0065] Furthermore, such as Figure 10 As shown, the end of the pin 1131 is beveled. During the installation of the side railing 113, pressing down on the end of the side railing 113 causes the pin 1131 to bend and press against the upper part of the pin opening 115 of the U-shaped bending block 114. The beveled surface is subjected to an inward pushing force, causing the pin 1131 to retract. When aligned with the pin opening 115, the pin 1131 is pushed out by the spring force and locks with the pin opening 115. The U-shaped bending block 114 restricts the side railing 113 from moving left, right, and downward, while the pin opening 115 and the pin 1131 restrict upward movement. When disassembling the side railing 113, prying open the pin ears 1132 on both sides causes the pin 1131 to retract into the lock body, disengaging the pin 1131 from the pin opening 115, allowing the side railing 113 to be removed.

[0066] The simple and durable pin mechanism makes the side railing 113 easy to install and remove. It can be installed by gently pressing it down, and the side railing 113 can be unlocked and removed by prying the pin ear 1132.

[0067] In a specific embodiment, such as Figures 8-10 As shown, the side guardrail 113 is a circular tube, and the lock body is placed at the end of the tube's cavity. A second clearance groove is provided on the circular tube to avoid the bolt lug 1132. Specifically, the lock body of the bolt mechanism can be welded to the inside of both ends of the circular tube.

[0068] Furthermore, this utility model also provides a vehicle including the vehicle guardrail device as described in the specific embodiments above. This vehicle can be a fire rescue vehicle, an emergency support vehicle, or other vehicle that needs to transport large packaging boxes.

[0069] The vehicle provided by this utility model can both quickly secure the packaging box 200 to the vehicle's trunk using the vehicle guardrail device 100, and also quickly disassemble it. Compared to other similar vehicles, it is faster and more reliable in securing and disassembling the packaging box 200.
