[0033] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0034] With urban development and rising environmental standards, the demand for cleaning central guardrails is increasing, leading to a rise in the frequency of use of guardrail cleaning equipment. Guardrail cleaning equipment is a mechanized tool specifically designed for cleaning urban road guardrails. Mounted on specialized vehicles, it uses rotating brushes or rollers in conjunction with high-pressure water spraying to clean the guardrails without moving them. Guardrail cleaning equipment offers advantages such as high efficiency, adaptability, and energy conservation.

[0035] However, the inventors discovered during the actual use of the guardrail cleaning device that, while driving and cleaning the guardrail, the operator was in the cab of the vehicle. Due to the obstruction of the guardrail cleaning device, the operator's field of vision was limited, making it impossible to accurately judge the position of the bottom of the guardrail cleaning device. This caused the guardrail cleaning device to collide with the mounting base of the guardrail frequently during actual use, resulting in damage to the guardrail cleaning equipment.

[0036] To address the aforementioned technical problems, this utility model provides a collision detection mechanism, guardrail cleaning device, and vehicle whose overall structure, working principle, and technical effects are described in detail below through embodiments and in conjunction with the accompanying drawings.

[0037] Please refer to Figure 1 This utility model discloses a vehicle, including a vehicle body 100 and a guardrail cleaning device 200, used for cleaning guardrails. The guardrail cleaning device 200 is installed on one side of the vehicle body 100. When cleaning the guardrail, the guardrail cleaning device 200 is engaged with the guardrail, and the vehicle is driven along the road, thereby cleaning the guardrail along its direction using the guardrail cleaning device 200. By mounting the guardrail cleaning device 200 on the vehicle, the effect of cleaning the guardrail while the vehicle is in motion can be achieved, offering advantages such as high efficiency and strong adaptability.

[0038] Please refer to Figure 2 This utility model also provides a guardrail cleaning device 200, applied to the aforementioned vehicle, for cleaning the guardrail during vehicle operation. The guardrail cleaning device 200 includes a telescopic arm, an inner roller brush, an outer roller brush, and an impact detection mechanism 300. The guardrail cleaning device 200 is detachably mounted on the vehicle via the telescopic arm, which can adjust the position of the guardrail cleaning device 200 horizontally and vertically to adapt it to the guardrail. The inner and outer roller brushes are arranged opposite each other on the telescopic arm, with a cleaning space between them for accommodating and cleaning the guardrail. During cleaning, the guardrail cleaning device 200 is driven to move, positioning the guardrail within the cleaning space between the inner and outer roller brushes, simultaneously contacting both brushes for cleaning. Furthermore, the impact detection mechanism 300 is installed at the bottom of both the inner and outer roller brushes. When the guardrail cleaning device 200 moves toward the guardrail mounting base, the impact detection mechanism 300 will first collide with the mounting base and detect the impact. An alarm will be set up inside the vehicle to remind the operator inside the vehicle to stop driving in time or adjust the position of the guardrail cleaning device 200 in time to avoid the guardrail cleaning device 200 colliding with the mounting base.

[0039] For further details, please refer to Figure 3 This utility model also provides an impact detection mechanism 300, which is applied to guardrail cleaning construction. The impact detection mechanism 300 is installed at the bottom of the aforementioned guardrail cleaning device 200 to detect the mounting base on the travel path of the guardrail cleaning device 200, so as to avoid the guardrail cleaning device 200 directly colliding with the guardrail mounting base and causing damage.

[0040] The impact detection mechanism 300 provided by this utility model includes a fixed plate 310, an impact plate 320, and a detection component 330. The fixed plate 310 is detachably installed at the bottom of the guardrail cleaning device 200, and the impact plate 320 is movably installed on the fixed plate 310. During the movement of the guardrail cleaning device 200, the impact plate 320 can move relative to the fixed plate 310 after being impacted. Since the guardrail cleaning device 200 moves along the length of the guardrail, the opposite direction of the movement of the guardrail cleaning device 200 is defined as the first direction, and the impact plate 320 moves along the first direction after being impacted. The detection component 330 connects both the fixed plate 310 and the impact plate 320, and is used to detect whether the fixed plate 310 has moved. Furthermore, an alarm (not shown in the attached drawings) is also installed inside the aforementioned vehicle. The detection component 330 is electrically connected to the alarm. When the detection component 330 detects an impact, the alarm is activated and sounds an alarm to alert the operators inside the vehicle.

[0041] By setting a fixed plate 310, an impact plate 320, and a detection component 330, the impact plate 320 is movably set on the fixed plate 310. When the impact plate 320 is impacted, it moves relative to the fixed plate 310. The detection component 330 is used to detect whether the impact plate 320 has moved relative to the fixed plate 310, thereby detecting the collision and preventing the guardrail cleaning device 200 from colliding with the mounting base, thus avoiding damage to the guardrail cleaning equipment to a certain extent.

[0042] Please refer to Figure 3 To facilitate the installation of the fixing plate 310 onto the bottom of the guardrail cleaning device 200, a connector for detachable connection to the guardrail cleaning device 200 is provided on the fixing plate 310. In this embodiment, the connector is a threaded hole, and the fixing plate 310 is detachably mounted to the bottom of the guardrail cleaning device 200 by bolts. In other embodiments, the connector can also be a flange, a snap-fit, or other structure, as long as the fixing plate 310 can be detachably connected to the guardrail cleaning device 200 via the connector; the specific structural form of the connector is not limited.

[0043] Please refer to Figure 3 In this embodiment, the fixing plate 310 is an elongated plate, which is disposed at the bottom of the guardrail cleaning device 200 along the first direction. The impact plate 320 includes a connecting portion 321 and impact portions 322 disposed at both ends of the connecting portion 321. The connecting portion 321 is disposed on the fixing plate 310 along the first direction. The impact portions 322 are perpendicular to the connecting portion 321, that is, the impact portions 322 are perpendicular to the first direction, thereby increasing the contact range between the impact plate 320 and the mounting base, facilitating contact between the impact plate 320 and the mounting base to achieve impact detection.

[0044] Furthermore, to prevent the impact plate 320 from moving irregularly upon impact, thus affecting the detection component 330's detection of the impact plate 320's movement, please refer to... Figure 3In this embodiment, a guide member 340 is also installed between the fixed plate 310 and the impact plate 320. The guide member 340 is used to ensure that the impact plate 320 can only move along a first direction after being impacted. In this embodiment, the guide member 340 includes a connecting rod. The impact plate 320 has a guide portion 323 that fits against the side of the fixed plate 310 facing the ground. A guide hole 324 is provided through the guide portion 323. Two guide holes 324 are spaced apart. The guide holes 324 are strip-shaped holes and extend along the first direction. The connecting rod is connected to the fixed plate 310 and passes through the guide hole 324. In this embodiment, the connecting rod is a bolt. The bolt thread passes through the fixed plate 310 and extends into the guide hole 324. A nut is fitted at the end of the bolt to prevent the impact plate 320 from detaching from the fixed plate 310. In other embodiments, the connecting rod may also be a cotter pin or other structure, as long as the impact plate 320 can only move relative to the fixed plate 310 in the first direction under the action of the connecting rod, and the impact plate 320 is prevented from detaching from the fixed plate 310.

[0045] Please refer to Figure 3 Furthermore, after the impact plate 320 impacts the guardrail mounting base and the operator drives the guardrail cleaning device 200 to move away from the guardrail mounting base, in order to allow the impact plate 320 to reset for the next impact detection, in this embodiment, the impact detection mechanism 300 also includes a reset component 350. The reset component 350 is connected between the fixed plate 310 and the impact plate 320, and is used to drive the impact plate 320 to reset after it moves. The reset component 350 includes a first mounting plate 351, a second mounting plate 352, and an elastic element 353. The first mounting plate 351 is disposed on the fixed plate 310, and the second mounting plate 352 is disposed on the impact plate 320. The elastic element 353 is connected between the first mounting plate 351 and the second mounting plate 352. After the impact plate 320 is impacted and moves relative to the fixed plate 310, the elastic element 353 ensures that the impact plate 320 always tends to reset to its initial position. In this embodiment, to improve the repositioning effect of the impact plate 320, two second mounting plates 352 are provided, with the first mounting plate 351 located between the two second mounting plates 352. An elastic element 353 is provided between the first mounting plate 351 and each of the two second mounting plates 352. In this embodiment, the elastic element 353 is configured as a spring; in other embodiments, the elastic element 353 can also be configured as a rubber component, a damper, or other structures.

[0046] Please refer to Figure 3In this embodiment, the detection component 330 includes a detection element 331 and a sensing plate 332. The detection element 331 is disposed on the fixed plate 310, and two sensing plates 332 are disposed on the impact plate 320. The two sensing plates 332 are respectively located on both sides of the detection element 331, and the detection element 331 is used to detect the sensing plates 332. In order to minimize the space of the impact detection mechanism 300, in this embodiment, the detection element 331 is disposed on the first mounting plate 351. In other embodiments, the detection element 331 may also be disposed separately on the fixed plate 310. Further, the detection element 331 includes at least one of a photoelectric sensor and a proximity sensor. In the initial position, the detection element 331 is located between the two sensing plates 332. When the impact plate 320 is impacted and moves relative to the impact plate 320, one of the sensing plates 332 moves with the impact plate 320 to be opposite the detection element 331. At this time, the detection element 331 detects the sensing plate 332 and controls the alarm inside the vehicle to start, realizing the effect of impact detection and alarm.

[0047] In summary, the implementation principle of the impact alarm mechanism, guardrail cleaning device 200, and vehicle provided by this utility model is as follows: by setting a fixed plate 310, an impact plate 320, and a detection component 330, the impact plate 320 is movably set on the fixed plate 310. When the impact plate 320 is impacted, it moves relative to the fixed plate 310. The detection component 330 is used to detect whether the impact plate 320 has moved relative to the fixed plate 310, thereby detecting the collision and preventing the guardrail cleaning device 200 from colliding with the mounting base, thus avoiding damage to the guardrail cleaning equipment to a certain extent.

[0048] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
