Description

[Technical Field]

[0001] This application belongs to the technical field of road construction crash protection vehicles, specifically relating to a crash protection vehicle with a rear-mounted light fixture. [Background Technology]

[0002] In traditional road construction crash barrier designs, the light holders are typically positioned at the front of the truck bed, behind the hood. Because of this location, the warning range is relatively short. When following vehicles attempt to use the light holders as a reference point to judge the safe distance, they cannot accurately determine the actual distance between their vehicle and the rear of the truck bed. This is because the light holder's position does not directly reflect the rear of the truck bed, potentially leading to driver misjudgment and increasing the risk of rear-end collisions. Furthermore, tools or equipment placed on the truck bed can partially obstruct the light holders, reducing their warning effectiveness and further increasing the risk of accidents. [Utility Model Content]

[0003] To address the problem that the position of the headlight bracket in existing crash protection vehicles cannot directly reflect the position of the rear of the vehicle, leading to driver misjudgment of distance, this application provides a crash protection vehicle with a rear-mounted headlight bracket.

[0004] This application is achieved through the following technical solution:

[0005] A rear-mounted light-mounted crash protection vehicle includes a frame body, a cargo box mounted on the frame body, a buffer pad located at the rear of the frame body, and a warning light assembly located at the rear of the cargo box and close to the buffer pad. When the buffer pad is extended relative to the frame body, its horizontal height is lower than the bottom of the warning light assembly. When the buffer pad is retracted relative to the frame body, its top horizontal height is lower than the top of the warning light assembly.

[0006] As described above, in a rear-mounted warning light assembly of a crash vehicle, a reinforcing plate is connected between the warning light assembly and the vehicle body. The reinforcing plate includes a first connecting portion connected to the inner wall of the vehicle body and a second connecting portion connected to the warning light assembly. The area of ​​the first connecting portion is larger than the area of ​​the second connecting portion.

[0007] As described above, in a rear-mounted warning light assembly crash vehicle, the second connecting portion has a sloping edge that gradually slopes downward from the top of the first connecting portion away from the first connecting portion, so as to form a triangular reinforcement zone between the warning light assembly and the vehicle body.

[0008] As described above, in a rear-mounted warning light assembly, a marker light is provided on the top of the warning light assembly.

[0009] As described above, in a rear-mounted warning light assembly for a crash vehicle, the warning light assembly includes a mounting frame and a lamp mounting plate disposed within the mounting frame for mounting the warning light. The lamp mounting plate is X-shaped and has multiple mounting positions for mounting the warning light.

[0010] As described above, a rear-mounted light fixture crash vehicle includes a frame body comprising a support frame and a side guard frame detachably connected to the support frame.

[0011] As described above, in a rear-mounted light fixture crash vehicle, the support frame includes multiple parallel longitudinal support beams and multiple crossbeams for connecting adjacent longitudinal support beams, and the side protection frame includes a side protection crossbeam detachably connected to the crossbeams and a side protection longitudinal beam connected to the crossbeams.

[0012] As described above, in a rear-mounted light fixture crash vehicle, the side protection beam includes a transverse portion parallel to the supporting beam, a longitudinal portion perpendicular to the side protection beam, and a chamfered portion located between the transverse portion and the longitudinal portion.

[0013] As described above, in a rear-mounted light fixture crash vehicle, the supporting frame is made of square tubing, and the side protection frame is made of channel steel.

[0014] As described above, in a rear-mounted light fixture crash vehicle, the side protection beam has slots, and the support beam has connecting holes corresponding to the slots. Fasteners pass through the slots and the connecting holes to connect the side protection beam and the support beam.

[0015] Compared with the prior art, this application has the following advantages:

[0016] This application discloses a rear-mounted warning light assembly for a crash protection vehicle. By placing the warning light assembly at the rear of the vehicle body and close to the buffer pad, it ensures that the warning light assembly remains at a horizontal height above the buffer pad when it is deployed or retracted. This directly reflects the position of the rear of the vehicle body, allowing following vehicles to accurately judge the safe distance to the rear of the vehicle body. This avoids the risk of rear-end collisions caused by drivers misjudging distances due to the position of the light assembly. At the same time, it prevents tools or equipment on the vehicle body from partially obstructing the light assembly, ensuring the warning effect of the light assembly and effectively improving the safety protection performance of the road construction crash protection vehicle.

Detailed Implementation Methods

[0024] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0025] Please see Figures 1 to 6 A rear-mounted light-mounted crash protection vehicle includes a frame body 1, a cargo box 2 disposed on the frame body 1, a buffer pad 3 disposed at the rear of the frame body 1, and a warning light holder assembly 4 disposed at the rear of the cargo box 2 and close to the buffer pad 3. When the buffer pad 3 is unfolded relative to the frame body 1, its horizontal height is lower than the bottom of the warning light holder assembly 4. When the buffer pad 3 is retracted relative to the frame body 1, its top horizontal height is lower than the top of the warning light holder assembly 4.

[0026] This application discloses a rear-mounted warning light assembly for a crash protection vehicle. By placing the warning light assembly at the rear of the vehicle body and close to the buffer pad, it ensures that the warning light assembly remains at a horizontal height above the buffer pad when it is deployed or retracted. This directly reflects the position of the rear of the vehicle body, allowing following vehicles to accurately judge the safe distance to the rear of the vehicle body. This avoids the risk of rear-end collisions caused by drivers misjudging distances due to the position of the light assembly. At the same time, it prevents tools or equipment on the vehicle body from partially obstructing the light assembly, ensuring the warning effect of the light assembly and effectively improving the safety protection performance of the road construction crash protection vehicle.

[0027] Furthermore, as a preferred embodiment of this solution and not a limitation, a reinforcing plate 5 is connected between the warning light bracket assembly 4 and the carriage 2. The reinforcing plate 5 includes a first connecting part 51 connected to the inner wall of the carriage 2 and a second connecting part 52 connected to the warning light bracket assembly 4. The area of ​​the first connecting part 51 is larger than the area of ​​the second connecting part 52.

[0028] In this embodiment, by providing a first connecting portion 51 connected to the inner wall of the carriage 2 and a second connecting portion 52 connected to the warning light bracket assembly 4, with the area of ​​the first connecting portion 51 being larger than the area of ​​the second connecting portion 52, this design significantly enhances the connection strength and stability between the warning light bracket assembly 4 and the carriage 2, effectively preventing the warning light bracket assembly 4 from loosening or falling off during vehicle operation or collision, thereby improving the safety and reliability of the overall structure. Furthermore, this reinforcing plate 5 design is not only suitable for rear-mounted crash vehicles but can also be applied to other vehicle structures requiring enhanced connection strength, such as the connection between the carriage and the frame, and the connection between the frame and other equipment.

[0029] Furthermore, as a preferred embodiment of this solution and not a limitation, the second connecting portion 52 is provided with a sloping side 53 that gradually slopes downward from the top of the first connecting portion 51 away from the first connecting portion 51, so as to form a triangular reinforcement area 54 between the warning light bracket assembly 4 and the carriage 2.

[0030] In this embodiment, by forming a triangular reinforcement zone 54 between the warning light bracket assembly 4 and the carriage 2, the support strength and deformation resistance of the reinforcing plate 5 are significantly enhanced by utilizing the stability principle of a triangle. This structural design not only effectively disperses and bears the gravity and external forces from the warning light bracket assembly 4, preventing the reinforcing plate 5 from bending or breaking, but also increases the tightness and reliability of the connection, ensuring that the warning light bracket assembly 4 remains stable under various working conditions.

[0031] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the top of the warning light holder assembly 4 is provided with a marker light 6.

[0032] In this embodiment, the placement of the marker lights ensures that the warning light assembly remains effective even when the buffer pad is retracted, preventing complete obstruction of the warning light assembly's light. This significantly improves the visibility of the crash barrier vehicle at night or in low visibility conditions, allowing following vehicles to detect and identify its presence earlier and take appropriate deceleration or evasive action, effectively preventing traffic accidents. The marker lights 6 not only enhance the passive safety of the crash barrier vehicle but also improve the overall safety of the construction site.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the warning light bracket assembly 4 includes a mounting frame 41 and a lamp body mounting plate 42 disposed within the mounting frame 41 for mounting the warning light. The lamp body mounting plate 42 is arranged in an X shape and has a plurality of mounting positions 43 for mounting the warning light.

[0034] In this embodiment, by providing a stable installation platform and a flexible layout, the installation efficiency and overall warning effect of the warning light are significantly improved. The design of the X-shaped lamp body mounting plate 42 not only enhances the structural strength of the mounting frame 41, but also optimizes the layout of the warning light, enabling the light to cover a wider area and provide all-round warning.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the frame body 1 includes a support frame 11 and a side guard frame 12 detachably connected to the support frame 11.

[0036] In this embodiment, a modular design is achieved by separating the support frame 11 from the side guard frame 12, bringing significant flexibility and convenience. First, the detachable side guard frame 12 facilitates quick replacement or adjustment according to different working environments and needs, simplifying the maintenance and repair process. When the side guard frame 12 is damaged, it can be replaced separately without disassembling the entire frame, saving time and costs. It is also more convenient and efficient to inspect and maintain the components at the bottom of the vehicle body.

[0037] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the support frame 11 includes a plurality of parallelly arranged support longitudinal beams 111 and a plurality of support crossbeams 112 for connecting adjacent support longitudinal beams 111, and the side protection frame 12 includes a side protection crossbeam 121 detachably connected to the support crossbeams 112 and a side protection longitudinal beam 122 connected to the side protection crossbeams 121.

[0038] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the side protection beam 121 includes a transverse portion 1211 arranged parallel to the support beam 112, a longitudinal portion 1212 perpendicular to the side protection beam 122, and a chamfered portion 1213 located between the transverse portion 1211 and the longitudinal portion 1212.

[0039] In this embodiment, optimizing the geometry of the side protective beam 121 brings multiple advantages. First, the transverse portion 1211 is arranged parallel to the supporting beam 112, ensuring good alignment and connection between the side protective beam 121 and the supporting frame 11, thus improving the stability and consistency of the overall structure. The longitudinal portion 1212 is perpendicular to the side protective longitudinal beam 122, providing necessary longitudinal support for the side protective frame 12 and enhancing its impact resistance and rigidity. The chamfered portion 1213 has multiple functions: it not only creates a smooth transition between the transverse portion 1211 and the longitudinal portion 1212, reducing stress concentration, but also improves the strength and durability of the side protective beam 121.

[0040] Furthermore, as a preferred embodiment of this solution and not a limitation, the support frame 11 is made of square tubing, and the side protection frame 12 is made of channel steel.

[0041] In this embodiment, square tubing, as the material for the supporting frame 11, provides excellent bending and torsional resistance due to its uniform wall thickness and cross-sectional shape, ensuring the rigidity and stability of the frame. Channel steel is used for the side guard frame 12, and its channel-shaped cross-section design effectively enhances the impact and compression resistance of the side guard frame 12. At the same time, the edges of the channel steel can also provide additional connection points, facilitating the fixing and assembly with other structural components.

[0042] Furthermore, as a preferred embodiment of this solution and not a limitation, the side protection beam 121 has a slot 1214, and the support beam 112 has a connecting hole 1121 corresponding to the slot 1214. Fasteners pass through the slot 1214 and the connecting hole 1121 to connect the side protection beam 121 and the support beam 112.

[0043] In this embodiment, the design of connecting the two components with fasteners provides a simple and efficient modular connection method, resulting in significant flexibility and maintainability. This design allows the side protection beam 121 and the support beam 112 to be quickly assembled and disassembled when needed, without the use of special tools or equipment. The cooperative use of the slot 1214 and the connecting hole 1121 enables fasteners such as bolts or pins to securely fix the side protection beam 121 to the support beam 112, ensuring the strength and reliability of the connection. This connection method can not only withstand various loads and stresses generated during vehicle operation and construction, but also allows for convenient adjustment and replacement. For example, if the side protection beam 121 is damaged, a new component can be quickly disassembled and replaced without extensive disassembly and repair of the entire vehicle frame.

[0044] The working principle of this embodiment is as follows:

[0045] This application discloses a rear-mounted warning light assembly for a crash protection vehicle. By placing the warning light assembly at the rear of the vehicle body and close to the buffer pad, it ensures that the warning light assembly remains at a horizontal height above the buffer pad when it is deployed or retracted. This directly reflects the position of the rear of the vehicle body, allowing following vehicles to accurately judge the safe distance to the rear of the vehicle body. This avoids the risk of rear-end collisions caused by drivers misjudging distances due to the position of the light assembly. At the same time, it prevents tools or equipment on the vehicle body from partially obstructing the light assembly, ensuring the warning effect of the light assembly and effectively improving the safety protection performance of the road construction crash protection vehicle.
