Description

[0001] This application relates to the field of obstacle removal equipment technology, and more particularly to an obstacle removal device and vehicle. Background Technology

[0002] In related technologies, to improve the snow-clearing effect of vehicle snow removal devices, common snow removal devices installed on vehicles usually include shock absorbers. These shock absorbers often serve both traction and damping functions, meaning they act as both a shock absorber and a tow bar (providing forward power to the snow removal device). When the shock absorber acts as a tow bar, it is subjected to shear force, which can easily cause it to break along the direction of the shear force. Utility Model Content

[0062] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0063] In related technologies, obstacle removal devices are used to remove obstacles such as snow from roads and other surfaces. The surface where the snow to be removed (such as the road surface) can be considered the working surface of the obstacle removal device. The obstacle removal device moves on the working surface, typically propelled by a vehicle equipped with it applying a thrust (i.e., traction force, as described below). Simultaneously, because the obstacle removal components (such as roller brushes) need to exert force on the working surface to ensure full contact with the snow for effective removal, the working surface exerts a reaction force on the device (i.e., the first force, as described below). Under the action of this first force, the obstacle removal components will move away from the working surface (i.e., the components lift relative to the working surface), resulting in poor performance. To reduce the impact of the first force on the snow removal effect, the obstacle removal device typically includes a shock-absorbing mechanism. In related technologies, the shock-absorbing mechanism of the obstacle removal device must simultaneously bear both the traction force and the first force. For ease of understanding, let's assume the obstacle-clearing device acts on a horizontal plane. The traction force can then be decomposed into two components: a horizontal component and a vertical component. Under the action of the first horizontal component, the shock-absorbing mechanism will deform in the direction of movement of the obstacle-clearing device, or break in the horizontal direction. If there is an angle between the shock-absorbing mechanism and the horizontal plane, and the tilt direction of the shock-absorbing mechanism is opposite to the direction of movement of the obstacle-clearing device (horizontally forward) (i.e., horizontally backward), then the first force can be decomposed into a second horizontal component and a second vertical component. The second horizontal component acts in opposite directions to the first horizontal component, and the second vertical component acts in opposite directions to the first vertical component. This will further exacerbate the deformation of the shock-absorbing mechanism.

[0064] In view of the above problems, this application provides a clearing device and vehicle to at least partially solve the above technical problems.

[0065] According to a first aspect of this application, a road clearing device is provided; please refer to [reference needed]. Figures 1 to 3 , Figure 1 This is a three-dimensional structural diagram of the obstacle clearing device provided in the embodiments of this application. Figure 2 yes Figure 1 A front view of the provided obstacle removal device. Figure 3 yes Figure 1 A top view of the provided obstacle removal device. The obstacle removal device includes: a support frame 10; an obstacle removal component 20, which is drivenly connected to the support frame 10; a shock absorption mechanism 30, configured to connect the vehicle and the support frame 10 and to keep the obstacle removal component 20 in continuous contact with the work surface; and a traction mechanism 50, configured to connect the vehicle and the support frame 10 to transmit power provided by the vehicle to the obstacle removal component 20, causing the obstacle removal component 20 to actuate and remove obstacles.

[0066] In this embodiment, the obstacle clearing device operates on the work surface, and includes a shock-absorbing mechanism 30 and a traction mechanism 50. The shock-absorbing mechanism 30 and the traction mechanism 50 are independent of each other. The shock-absorbing mechanism 30 mainly bears the force exerted on the obstacle clearing device by the work surface and does not bear the traction force. This makes the shock-absorbing mechanism 30 unaffected by the component of the traction force parallel to the work surface, which can reduce the probability of damage to the shock-absorbing mechanism 30 in the direction parallel to the work surface and help to improve the service life of the shock-absorbing mechanism 30.

[0067] In some embodiments of this application, the obstacle clearing component 20 is a snow removal component. The snow removal component can be a roller brush.

[0068] In some embodiments of this application, the bracket 10 has a first connecting structure 11 and a second connecting structure 12, and the two ends of the obstacle clearing member 20 are rotatably connected to the first connecting structure 11 and the second connecting structure 12, respectively.

[0069] In this embodiment, the two ends of the obstacle clearing component 20 are rotatably connected to the first connecting structure 11 and the second connecting structure 12 of the bracket 10, respectively. On one hand, this rotatable connection ensures that the obstacle clearing component 20 can rotate smoothly to clear obstacles. On the other hand, compared to a single-point connection, the connection method in this application, which connects both ends of the obstacle clearing component 20 to the bracket 10, improves the connection stability between the obstacle clearing component 20 and the bracket 10. Furthermore, with a single-point connection, the obstacle clearing component 20 is prone to tilting during obstacle clearing, affecting the obstacle clearing effect. The connection method between the obstacle clearing component 20 and the bracket 10 provided in this application avoids tilting of the obstacle clearing component 20. Therefore, the connection method between the obstacle clearing component 20 and the bracket 10 provided in this application also ensures the obstacle clearing effect.

[0070] In some embodiments of this application, the bracket 10 has a shock-absorbing mounting portion, and the shock-absorbing mechanism 30 is connected to the shock-absorbing mounting portion.

[0071] In some embodiments of this application, the bracket 10 further includes a traction mounting portion 14, to which the traction mechanism 50 is connected.

[0072] In some embodiments of this application, the bracket 10 has a shock-absorbing mounting portion, and the shock-absorbing mechanism 30 is connected to the shock-absorbing mounting portion; the traction mechanism 50 includes a traction member 51, the extension direction of which is parallel to the direction of the force exerted by the working surface on the obstacle clearing device.

[0073] By adopting this scheme, the traction mechanism 50 and the shock absorption mechanism 30 can be connected to different parts of the bracket 10, further separating the shock absorption mechanism 30 and the traction mechanism 50. This can prevent the shock absorption mechanism 30 from bearing the traction force and help to further improve the service life of the shock absorption mechanism 30.

[0074] In some embodiments of this application, the shock absorption mechanism 30 includes a shock absorber 31, the extension direction of which is set at an angle to the direction of the force exerted by the working surface on the obstacle removal device.

[0075] In this embodiment, the angle between the extension direction of the shock absorber 31 and the direction of the force exerted by the working surface on the obstacle clearing device can be 15° or 30°, etc. The specific angle can be determined according to the actual situation, and this application does not limit it.

[0076] In some embodiments of this application, the extension direction of the shock absorber 31 is parallel to the direction of the force exerted by the working surface on the obstacle clearing device.

[0077] With this design, the force exerted by the working surface on the obstacle clearing device will be directly transmitted to the vehicle along the shock absorber 31, without generating a component force parallel to the working surface. This reduces the force on the shock absorber 31 in the direction parallel to the working surface, thereby reducing the probability of damage to the shock absorber 31 in the direction parallel to the working surface and also helping to improve the service life of the shock absorber 31.

[0078] In some embodiments of this application, the shock-absorbing mounting part includes: a shock-absorbing connecting rod 13, with its two ends fixedly connected to the first connecting structure 11 and the second connecting structure 12 respectively, and a shock absorber 31 connected to the shock-absorbing connecting rod 13.

[0079] The first connecting structure 11 and the second connecting structure 12 are respectively connected to the two ends of the obstacle removal device. Therefore, in this embodiment, the first connecting structure 11 and the second connecting structure 12 are connected by the shock-absorbing connecting rod 13, and the shock absorber 31 is connected to the shock-absorbing connecting rod 13. The force exerted by the working surface on the obstacle removal device during the obstacle removal process (or during the movement) of the obstacle removal component 20 can be transmitted to the shock absorber 31 along the first connecting structure 11, the second connecting structure 12 and the shock-absorbing connecting rod 13. The shock absorber 31 is used to buffer the force, so that the obstacle removal component 20 continues to contact the working surface and ensures the obstacle removal effect of the obstacle removal device.

[0080] In some embodiments of this application, the shock absorption mechanism 30 includes a plurality of shock absorbers 31, which are spaced apart along the axial direction of the obstacle clearing member 20.

[0081] This approach allows multiple shock absorbers 31 to distribute the force exerted on the obstacle clearing device by the working surface, reducing the force borne by each individual shock absorber 31. This lowers the probability of damage to a single shock absorber 31 and extends its service life. Furthermore, it expands the range of forces the obstacle clearing device can withstand from the working surface, thereby broadening the applicability of the obstacle clearing device provided in this application.

[0082] In some embodiments of this application, the shock absorption mechanism 30 has two shock absorbers 31, which are respectively disposed at both ends of the shock absorption connecting rod 13.

[0083] This design allows the two shock absorbers 31 to distribute the force exerted on the obstacle-clearing device by the working surface, thereby extending the service life of the shock absorbers 31. Simultaneously, by positioning the two shock absorbers 31 at opposite ends of the shock-absorbing connecting rod 13, the force transmission path between the shock absorbers 31 and the obstacle-clearing component 20 is shortened. This facilitates rapid buffering of the force by the shock absorbers 31, reducing the time it takes for the obstacle-clearing component 20 to separate from the working surface, thus ensuring the obstacle-clearing device's effectiveness in removing obstacles. Furthermore, the first connecting structure 11 and the second connecting structure 12, respectively connected to the two ends of the obstacle-clearing component 20 and the shock-absorbing connecting rod 13, ensure continuous contact between both ends of the obstacle-clearing component 20 and the working surface, preventing one end of the obstacle-clearing component 20 from lifting and separating from the working surface, thus improving the reliability of the obstacle-clearing device provided in this application.

[0084] In some embodiments of this application, the traction mechanism 50 includes a traction member 51, the extension direction of which is set at an angle to the direction of the force exerted by the working surface on the obstacle clearing device.

[0085] In some embodiments of this application, the traction mechanism 50 includes a traction member 51, the extension direction of which is parallel to the direction of the force exerted by the working surface on the obstacle clearing device. The technical effects are similar to or the same as those of the embodiment described above, where the shock absorption mechanism 30 includes a shock absorber 31, the extension direction of which is parallel to the direction of the force exerted by the working surface on the obstacle clearing device, and will not be repeated here.

[0086] In some embodiments of this application, the traction mounting part 14 includes: a traction connecting rod 141, with its two ends connected to the first connecting structure 11 and the second connecting structure 12 respectively, and the traction mechanism 50 connected to the traction connecting rod 141.

[0087] By adopting this scheme, the traction force of the vehicle acting on the obstacle removal device can be transmitted along the two ends of the traction connecting rod 141 to the first connecting structure 11 and the second connecting structure 12, and then transmitted to the two ends of the obstacle removal component 20 through the first connecting structure 11 and the second connecting structure 12, so that both ends of the obstacle removal component 20 are subjected to force, which helps the obstacle removal component 20 to rotate and remove obstacles.

[0088] In some embodiments of this application, the traction mechanism 50 is connected to the middle of the traction connecting rod 141. In this way, the traction force exerted by the vehicle on the obstacle clearing device can be evenly distributed along the traction connecting rod 141 to the first connecting structure 11 and the second connecting structure 12, that is, the force on both ends of the obstacle clearing component 20 is basically the same, which can prevent the obstacle clearing component 20 from tilting and help improve the obstacle clearing efficiency of the obstacle clearing component 20.

[0089] In some embodiments of this application, the traction mounting part 14 further includes two traction rods 142, which are respectively connected to the first connecting structure 11 and the second connecting structure 12. The traction connecting rod 141 is hinged to the two traction rods 142. In this way, the hinged traction rods 142 and traction connecting rod 141 can absorb the small lateral and vertical rotational changes generated by the obstacle clearing device during operation, ensuring the normal operation of the obstacle clearing device.

[0090] In some embodiments of this application, the traction rod 142 and the traction connecting rod 141 are connected by a ball joint hinge.

[0091] In some embodiments of this application, the obstacle clearing device further includes: a traveling mechanism 70, which is rotatably connected to the bracket 10, and the rotating shaft of the traveling mechanism 70 is arranged parallel to the rotating shaft of the obstacle clearing device. The traveling mechanism 70 is configured to rotate under the drive of the vehicle to move the obstacle clearing device.

[0092] In some embodiments of this application, the traveling mechanism 70 includes: a drive shaft 71, both ends of which are rotatably connected to the first connecting structure 11 and the second connecting structure 12 respectively; and a traveling wheel 72, which is fixedly connected to the drive shaft 71.

[0093] Please see Figures 1 to 5 , Figure 4 yes Figure 1 A side view of the provided obstacle removal device. Figure 5 yes Figure 1 A partial cross-sectional view of the provided obstacle clearing device shows the transmission mechanism 80. In some embodiments of this application, the obstacle clearing device further includes a transmission mechanism 80, which is tractively connected to the traveling mechanism 70 and the obstacle clearing member 20, so that the obstacle clearing member 20 rotates with the traveling wheel 72.

[0094] This approach allows for synchronized rotation of the obstacle clearing component 20 and the traveling mechanism 70. Furthermore, when the obstacle clearing component 20 clears obstacles, the obstacles exert resistance on it. By connecting the obstacle clearing component 20 and the traveling mechanism 70, the traveling mechanism 70 can drive the obstacle clearing component 20 to rotate, overcoming the resistance of the obstacles and improving the obstacle clearing efficiency and effectiveness of the obstacle clearing device.

[0095] In some embodiments of this application, the transmission mechanism 80 includes: a first transmission wheel 81, disposed on and fixedly connected to the transmission shaft 71; a second transmission wheel 82, meshing with the first transmission wheel 81; and a third transmission wheel 83, fixedly connected to the obstacle clearing member 20, and connected to the second transmission wheel 82 via a transmission chain 84. This allows the rotation direction of the obstacle clearing member 20 to be opposite to the rotation direction of the traveling wheel 72 of the traveling mechanism 70, which helps to clear obstacles outside the vehicle's travel path, reduces the impact of obstacles on vehicle travel, and improves the reliability of the obstacle clearing device provided in this application.

[0096] In some embodiments of this application, the transmission mechanism 80 and the first connecting structure 11 are disposed on the same side of the obstacle clearing member 20. The transmission mechanism 80 further includes a connecting shaft 85, which is disposed on the side opposite to the traveling mechanism 70 from the first connecting structure 11. A second transmission wheel 82 is connected to the connecting shaft 85, and the connecting shaft 85 is configured to support the second transmission wheel 82 so that the second transmission wheel 82 moves with the movement of the first transmission wheel 81. Thus, the connecting shaft 85 can be used to connect the second transmission wheel 82 to the first connecting structure 11, providing support for the second transmission wheel 82. To enable the second transmission wheel 82 to rotate, the second transmission wheel 82 can be fixedly connected to the connecting shaft 85, while the connecting shaft 85 can be rotatably connected to the first connecting structure 11. For example, a bearing can be provided at the connection between the connecting shaft 85 and the first connecting structure 11. Alternatively, the connecting shaft 85 can be fixedly connected to the first connecting structure 11, the second transmission wheel 82 can be sleeved on the connecting shaft 85, and a bearing can be provided between the second transmission wheel 82 and the connecting shaft 85. The specific connection method used can be determined based on the actual situation, and this application does not impose any restrictions on it.

[0097] In some embodiments of this application, the transmission mechanism 80 and the second connecting structure 12 are disposed on the same side of the obstacle clearing member 20. The transmission mechanism 80 further includes a connecting shaft 85, which is disposed on the side opposite to the second connecting structure 12 and the traveling mechanism 70. The second transmission wheel 82 is connected to the connecting shaft 85, and the connecting shaft 85 is configured to support the second transmission wheel 82 so that the second transmission wheel 82 moves with the movement of the first transmission wheel 81. The technical effects are similar or the same as those of the embodiment where the connecting shaft 85 is disposed on the side opposite to the first connecting structure 11 and the traveling mechanism 70, and will not be described again here.

[0098] In some embodiments of this application, the obstacle clearing device further includes a shock absorber mounting base 40, through which the shock absorber mechanism 30 is configured to connect to the vehicle. This increases the connection area between the shock absorber mechanism 30 and the vehicle by utilizing the shock absorber mounting base 40, preventing damage to the vehicle or shock absorber mechanism 30 due to excessive force concentration transmitted through the shock absorber mechanism 30, thus contributing to the reliability of the obstacle clearing device.

[0099] In some embodiments of this application, the obstacle clearing device further includes a towing mount 60, and the towing mechanism 50 is configured to be connected to the vehicle via the towing mount 60. The technical effects are similar or identical to those of the embodiments in which the obstacle clearing device also includes a shock-absorbing mount 40, and will not be described again here.

[0100] In some embodiments of this application, the shock-absorbing mechanism 30 is disposed between the obstacle-clearing component 20 and the traction mechanism 50. This brings the shock-absorbing mechanism 30 closer to the obstacle-clearing component 20, better buffering the force exerted by the working surface on the obstacle-clearing device. Simultaneously, it shortens the force transmission path applied by the shock-absorbing mechanism 30 to the obstacle-clearing component 20, resulting in greater pressure on the obstacle-clearing component 20. This facilitates continuous contact between the obstacle-clearing component 20 and the working surface, improving the efficiency and effectiveness of obstacle removal.

[0101] According to a second aspect of this application, a vehicle is provided, including the obstacle clearing device described above. This vehicle possesses all the beneficial effects of the aforementioned obstacle clearing device, which will not be elaborated further herein.

[0102] The vehicle may be a gasoline-powered vehicle, a plug-in hybrid electric vehicle, or a new energy vehicle, etc., and this application does not make any specific restrictions.

[0103] In some embodiments of this application, the vehicle has a bogie and a body, the shock absorber mount 40 of the obstacle clearing device is mounted on the bogie or the body, and / or the traction mount 60 of the obstacle clearing device is configured to be mounted on the bogie or the body.

[0104] In this embodiment, the shock-absorbing mounting base 40 and / or the traction mounting base 60 are configured to be mounted on the bogie. This helps to reduce the vibration of the obstacle clearing device and improve its obstacle clearing effect.

[0105] In some embodiments of this application, the vehicle is a rail transit vehicle.
