Description

Technical Field

[0001] This utility model relates to the field of snow removal equipment technology, and more specifically, to a working vehicle. Background Technology

[0002] A snowplow is a vehicle used to clear snow from roads. It uses snowplows mounted on its frame to push snow to one or both sides of the road. The snowplows are usually mounted on the side of the vehicle, and because their position is off-center from the driver's main field of vision, the operator mainly relies on the rearview mirror to observe the relative distance between the snowplow and the road guardrail.

[0003] However, in actual operation, drivers need to concentrate on observing the road conditions ahead of the vehicle, making it difficult to continuously monitor the position of the snowplow. If the snowplow is too close to the guardrail and is not noticed in time, it may lead to a serious safety accident, endangering the personal safety of the operators. Utility Model Content

[0040] As described in the background section, snowplows are typically mounted on the side of vehicles. Because their position is off-center from the driver's main field of vision, operators primarily rely on rearview mirrors to observe the relative distance between the snowplow and the road guardrail. However, in actual operation, the driver needs to concentrate on observing the road conditions ahead of the vehicle, making it difficult to continuously monitor the snowplow's position. If the distance between the snowplow and the guardrail is too close and not detected in time, it could lead to a serious safety accident, endangering the personal safety of the operator.

[0041] Based on this, please refer to Figures 1-5 The present invention provides a working vehicle 100 that effectively improves the aforementioned technical problems, namely, it enhances the safety of snow removal operations. The working vehicle 100 will be described in detail below.

[0042] Please refer to Figure 1 and Figure 2 , Figure 1 This is a structural schematic diagram of the work vehicle 100 provided in this embodiment. Figure 2 This is a diagram showing the positional relationship between the work vehicle 100 and the roadside fixed object 200 provided in this embodiment. (In conjunction with...) Figure 1 and Figure 2 The working vehicle 100 includes a frame 10, a working device 20, a distance sensor 30, and a controller (not shown). The working device 20 is mounted on the frame 10, and the distance sensor 30 is mounted on the frame 10 and located on the same side of the frame 10 as the working device 20. The distance sensor 30 is used to detect the distance between its emitting surface and a roadside fixed object 200. The controller is electrically connected to the distance sensor 30 and is used to output an alarm command when the distance between the emitting surface of the distance sensor 30 and the roadside fixed object 200 is less than or equal to a preset distance.

[0043] In other words, by setting a distance sensor 30 to detect the distance between the vehicle and the roadside fixed object 200, when the distance is less than or equal to the preset distance L, the controller outputs an alarm command to remind the driver to pay attention to the distance and adjust the vehicle status in time, so as to ensure that the working device 20 and the roadside fixed object 200 maintain a safe distance, thereby avoiding safety accidents and improving the safety of snow removal operations.

[0044] It should be noted that the location of the controller is not limited; it can be installed on the chassis 10, in the cab, or in other locations on the work vehicle 100. Additionally, it should be noted that in this embodiment, the distance sensor 30 is a millimeter-wave radar sensor, which can perform long-distance detection and has high accuracy; of course, in other embodiments, the distance sensor 30 can also be an infrared sensor or an optical sensor, etc.

[0045] Additionally, it should be noted that the roadside fixed object 200 can be a guardrail, green belt, bridge pier, building wall or fence, or other immovable object or structure set on the edge of the road.

[0046] like Figure 2 As shown, when the working device 20 is in the working position, the distance between the emitting surface of the distance sensor 30 and the roadside fixed object 200 is L1, the distance between the emitting surface of the distance sensor 30 and the axis of symmetry of the vehicle frame 10 is L2, the distance between the end of the working device 20 away from the vehicle frame 10 and the axis of symmetry of the vehicle frame 10 is L3, and the distance between the end of the working device 20 away from the vehicle frame 10 and the roadside fixed object 200 is L0. It is easy to understand that when the working vehicle 100 is in the working position... Figure 2 When the position is shown, the relationship between the above distance values ​​is: L1 = L0 + L3 - L2, that is, when L1 ≤ L (preset distance), the controller outputs an alarm command.

[0047] It should be noted that the axis of symmetry of frame 10 is... Figure 2 The X-axis is defined as follows. When the distance sensor 30 is mounted on the frame 10, its position remains unchanged; that is, the distance L2 between the emitting surface of the distance sensor 30 and the axis of symmetry of the frame 10 is a constant. Similarly, when the working device 20 is in its working position for snow removal, the overall position of the working device 20 remains essentially unchanged (during snow removal, the swing amplitude of the working device 20 is slight, and the error is negligible); that is, the distance L3 between the end of the working device 20 furthest from the frame 10 and the axis of symmetry of the frame 10 is also a constant. In other words, the method of comparing the actual change in distance L1 detected by the distance sensor 30 with the preset distance can be understood as a comparison between the distance L0 between the end of the working device 20 furthest from the frame 10 and the roadside fixed object 200, and the safe distance that the working device 20 needs to maintain.

[0048] In a straightforward manner, when setting up the program, the relevant parameter values ​​L2 and L3 of the work vehicle 100 can be input into the controller first. Then, the required safe distance L0 between the end of the work device 20 furthest from the frame 10 and the roadside fixed object 200 can be set. Thus, during snow removal by the work vehicle 100, the vehicle's status will change, causing the distance sensor 30 to detect a change in value L1. When the controller receives a value L1 ≤ L (the preset distance), it can be understood that the distance between the end of the work device 20 furthest from the frame 10 and the roadside fixed object 200 is less than or equal to the required safe distance. At this point, the controller will output an alarm command to remind the driver to adjust the vehicle's status in time to prevent the end of the work device 20 furthest from the frame 10 from getting too close to the roadside fixed object 200, ensuring the safety of snow removal operations.

[0049] Of course, in some implementations, the controller can also calculate the value of L1+L2-L3 and compare the difference with the set value of the safe distance that needs to be maintained between the end of the working device 20 away from the frame 10 and the roadside fixed object 200 to determine whether an alarm command needs to be sent to remind the driver.

[0050] Please continue to combine Figure 1 and Figure 2 To better alert the driver, in this embodiment, the work vehicle 100 also includes an alarm (not shown). The alarm is electrically connected to the controller and is used to output an alarm signal after receiving an alarm command. For example, the alarm can emit a voice alarm signal to remind the driver to pay attention to the distance.

[0051] Optionally, the distance sensor 30 and the working device 20 are spaced apart at the end closest to the frame 10. This avoids the working device 20 affecting the detection of the distance sensor 30 during snow removal, ensuring the working stability and detection accuracy of the distance sensor 30.

[0052] Specifically, in this embodiment, the frame 10 has a first axle 11, a second axle 12, and a third axle 13, with the distance sensor 30 located between the first axle 11 and the second axle 12. Furthermore, the frame 10 also has a front crossbeam 14 and a rear crossbeam 15, with both the second axle 12 and the third axle 13 located between the front crossbeam 14 and the rear crossbeam 15. The working device 20 is connected to both the front crossbeam 14 and the rear crossbeam 15, facilitating the installation of the working device 20 and improving its connection stability.

[0053] Furthermore, the work vehicle 100 also includes a detection device electrically connected to the controller, which is used to detect whether the work device 20 is in the working position. That is, when the detection device detects that the work device 20 is in the working position, it outputs a working command to the controller, thereby activating the edge-touching warning function of the work vehicle 100; when the detection device detects that the work device 20 is not in the working position, the controller does not activate the edge-touching warning function, that is, it does not output an alarm command, thereby avoiding misjudgment of the warning function and causing driver misoperation.

[0054] Combination Figure 1 The working device 20 includes a shovel plate 21, a swing assembly 22, a rotating bracket 23, and a lifting assembly 24. The shovel plate 21 is hinged to the swing assembly 22, the rotating bracket 23 is hinged to the swing assembly 22, and the lifting assembly 24 is hinged to the rotating bracket 23. The lifting assembly 24 is mounted on the frame 10. Specifically, in this embodiment, the lifting assembly 24 is connected to the front crossbeam 14 of the frame 10. The detection device includes a first position sensor 41 and a second position sensor 42. The first position sensor 41 is mounted on the swing assembly 22, and the second position sensor 42 is mounted on the lifting assembly 24.

[0055] By incorporating the swing assembly 22, the swing angle of the shovel 21 can be adjusted during snow removal, allowing the shovel 21 to overcome obstacles, reducing damage to the shovel 21, and improving snow removal efficiency. Similarly, by incorporating the lifting assembly 24, the shovel 21 can be raised and lowered, enabling it to overcome obstacles, thereby reducing damage and improving snow removal efficiency. Furthermore, by incorporating the first position sensor 41 and the second position sensor 42, the states of the swing assembly 22 and the lifting assembly 24 can be detected respectively, thereby determining whether the shovel 21 is in the working position.

[0056] For details, please refer to Figure 3 , Figure 3 This is a partial structural schematic diagram of the working device 20 provided in this embodiment, combined with... Figure 1 and Figure 3 The swing assembly 22 includes a swing hydraulic cylinder 221, a swing arm 222, and a swing arm mounting base 223. The fixed end of the swing hydraulic cylinder 221 is hinged to the rotating bracket 23, the movable end of the swing hydraulic cylinder 221 is hinged to the swing arm 222, and the end of the swing arm 222 away from the swing hydraulic cylinder 221 is hinged to the swing arm mounting base 223. The swing arm mounting base 223 is fixedly connected to the shovel plate 21. The first position sensor 41 is disposed on the swing hydraulic cylinder 221.

[0057] In other words, the first position sensor 41 can detect the extension and retraction position of the swing hydraulic cylinder 221, that is, detect whether the movable end of the swing hydraulic cylinder 221 extends to the working position, thereby determining whether the shovel plate 21 is in the working position.

[0058] Furthermore, in order to allow the shovel plate 21 to have a certain amount of room to move when it encounters an obstacle and to avoid damage to the swing hydraulic cylinder 221, in this embodiment, there is a buffer space between the end of the swing arm 222 away from the swing hydraulic cylinder 221 and the swing arm mounting base 223.

[0059] Please refer to Figure 4 and Figure 5 , Figure 4 This is a first-view structural schematic diagram of the lifting assembly 24 provided in this embodiment. Figure 5 This is a structural schematic diagram of the lifting assembly 24 provided in this embodiment from a second perspective, combined with... Figure 1 , Figure 4 and Figure 5 Specifically, the lifting assembly 24 includes a lifting bracket 241, a lifting hydraulic cylinder 242, and a slider 243. The lifting bracket 241 is connected to the vehicle frame 10. The fixed end of the lifting hydraulic cylinder 242 is hinged to the lifting bracket 241, and the movable end of the lifting hydraulic cylinder 242 is hinged to the slider 243. The slider 243 is slidably disposed on the lifting bracket 241, and the rotating bracket 23 is hinged to the slider 243. The second position sensor 42 is disposed on the lifting hydraulic cylinder 242.

[0060] Similarly, the second position sensor 42 can detect the extension and retraction position of the lifting hydraulic cylinder 242, that is, detect whether the movable end of the lifting hydraulic cylinder 242 extends to the working position, thereby determining whether the shovel plate 21 is in the working position.

[0061] Furthermore, to achieve the passive obstacle avoidance function of the shovel plate 21, in this embodiment, the slider 243 is provided with an obstacle avoidance hole 2431, and the movable end of the lifting hydraulic cylinder 242 is provided with a lifting shaft 2421. The lifting shaft 2421 passes through the obstacle avoidance hole 2431 and is hinged to the slider 243. It can be understood that when the shovel plate 21 encounters an obstacle during snow removal, the shovel plate 21 can move the slider 243 relative to the lifting shaft 2421 of the lifting hydraulic cylinder 242 under the action of the obstacle avoidance hole 2431 through the rotating bracket 23. This allows the shovel plate 21 to be passively raised and lowered to overcome the obstacle, thereby protecting the shovel plate 21, improving the service life of the shovel plate 21, and enhancing the overall stability of the working device 20.

[0062] Optionally, in order to improve the connection strength between the lifting bracket 241 and the vehicle frame 10 and to facilitate the connection with the front crossbeam 14 of the vehicle frame 10, the lifting assembly 24 further includes a connecting arm 244, which is disposed on the lifting bracket 241 and is connected and fixed to the front crossbeam 14 of the vehicle frame 10.

[0063] Please continue to combine Figure 1The working device 20 also includes a support and buffer structure 25, one end of which is hinged to the shovel plate 21, and the other end of which is hinged to the rear crossbeam 15 of the frame 10. By setting up the support and buffer structure 25, the shovel plate 21 can be provided with better support and buffering during snow removal, thereby improving the overall reliability of the working device 20 and also improving the snow removal efficiency to a certain extent.

[0064] Optionally, the working device 20 also includes a flexible protective plate 26, which is located at the end of the shovel plate 21 away from the rotating support 23, or the end of the shovel plate 21 away from the frame 10. By providing the flexible protective plate 26, a flexible buffering effect is provided when the rear of the shovel plate 21 collides, thereby effectively ensuring operational safety, improving the overall structural reliability, and extending the service life of the shovel plate 21. Furthermore, the flexible protective plate 26 can be disassembled and replaced individually, facilitating maintenance and reducing maintenance costs.

[0065] To improve the service life of the shovel plate 21, the working device 20 also includes a wear-resistant block 27, which is disposed on the shovel plate 21.

[0066] It should be noted that there can be multiple wear-resistant blocks 27, which are spaced apart along the length of the shovel plate 21, providing wear protection for the shovel plate 21 at different locations, thereby further improving its service life. In summary, this utility model provides a work vehicle 100, which includes a frame 10, a working device 20, a distance sensor 30, and a controller. The working device 20 is mounted on the frame 10, and the distance sensor 30 is mounted on the frame 10 and located on the same side of the frame 10 as the working device 20. The distance sensor 30 is used to detect the distance between its emitting surface and a roadside fixed object 200. The controller is electrically connected to the distance sensor 30 and outputs an alarm command when the distance between the emitting surface of the distance sensor 30 and the roadside fixed object 200 is less than or equal to a preset distance. By setting a distance sensor 30 to detect the distance between the vehicle and the roadside fixed object 200, when the distance is less than or equal to the preset distance, the controller outputs an alarm command to remind the driver to pay attention to the distance and adjust the vehicle status in time, so as to ensure that the working device 20 and the roadside fixed object 200 maintain a safe distance, thereby avoiding safety accidents and improving the safety of snow removal operations.
