[0002] Snowplows, as emergency road support equipment, play a vital role in ensuring traffic safety and improving road efficiency during snowy weather. With the increasing number of vehicles in my country, snow on roads that is not cleared promptly during snowfall will be crushed and compacted by vehicles, forming ice. Vehicles with both snow removal and ice-breaking functions are increasingly common. However, the control of the ice-breaking and snow-clearing devices currently available on the market relies heavily on operator experience, often leading to poor ice-breaking and snow-clearing performance due to inadequate operation.

[0060] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0061] Example

[0062] See also Figure 1 , Figure 1 Shown is a structural schematic diagram of the ice-breaking and snow-removing vehicle 100 provided in this embodiment.

[0063] The ice-breaking and snow-removing vehicle 100 provided in this embodiment is equipped with an ice-breaking and snow-removing system. The ice-breaking and snow-removing system includes an ice-breaking device 120, which includes an ice-breaking element 121, a first rotating drive element (not shown), and a first lifting drive element 122. The first rotating drive element is transmission-connected to the ice-breaking element 121 for rotating the ice-breaking element 121 to break the ice surface; the first lifting drive element 122 is transmission-connected to the ice-breaking element 121 for raising or lowering the ice-breaking element 121. In this embodiment, the first rotating drive element is a hydraulic motor, and the first lifting drive element 122 is a hydraulic cylinder.

[0064] The ice breaking and snow removing system provided in this embodiment also includes a first rotational pressure detection component and a first ground pressure detection component. The first rotational pressure detection component is used to detect the first rotational pressure of the first rotating drive component, and the first ground pressure detection component is used to detect the first ground pressure of the first lifting drive component 122.

[0065] Please refer to Figure 2 , Figure 2 FIG. 1 is a schematic structural diagram of the ice breaking device 120 .

[0066] When ice breaking begins, first lifting drive 122 drives ice breaking element 121 downward until the first ground pressure reaches a preset first ground pressure range. In practice, a damping spring 123 is connected between first lifting drive 122 and ice breaking element 121. As the first rotary drive drives ice breaking element 121 to rotate and break the ice, ice breaking element 121 bounces slightly up and down. These small fluctuations in the first ground pressure are absorbed by damping spring 123. The greater the rotational resistance of ice breaking element 121, the greater the first rotational pressure. When ice breaking element 121 rotates and breaks the ice, the first rotational pressure remains within the preset first rotational pressure range.

[0067] When a pothole appears on the ground, ice-breaking element 121 is suspended in the air, and both the first rotational pressure and the first ground pressure reach their minimum values, making it impossible to effectively break the ice. When a non-ice-covered bump appears on the ground, the first rotational pressure will exceed the upper limit of the first rotational pressure range, and the first ground pressure will also exceed the upper limit of the first ground pressure range, causing damage to the ground.

[0068] In order to obtain a better ice-breaking effect and prevent damage to the ground, the ice-breaking and snow-removing vehicle 100 provided in this embodiment also includes a controller, which obtains the first rotational pressure and the first ground pressure in real time, and compares the first rotational pressure with the preset first rotational pressure range in real time to obtain a first comparison result; compares the first ground pressure with the preset first ground pressure range in real time to obtain a second comparison result; and then controls the first lifting drive component 122 to drive the ice-breaking component 121 to rise or fall according to at least one of the first comparison result and the second comparison result.

[0069] Specifically, when the first comparison result indicates that the first rotational pressure is greater than the upper limit value of the first rotational pressure range, and the second comparison result indicates that the first ground pressure is greater than the upper limit value of the first ground pressure range, the first lifting drive member 122 is controlled to drive the ice-breaking member 121 to rise until the first rotational pressure is within the first rotational pressure range and the first ground pressure is within the first ground pressure range.

[0070] If the first comparison result indicates that the first rotational pressure is less than the lower limit of the first rotational pressure range, the first lifting drive member 122 is controlled to drive the ice-breaking member 121 downward until the first rotational pressure is within the first rotational pressure range. Furthermore, if the second comparison result indicates that the first ground pressure is less than the lower limit of the first ground pressure range, the first lifting drive member 122 is controlled to drive the ice-breaking member 121 downward until the first ground pressure is within the first ground pressure range.

[0071] Furthermore, considering that if the vehicle is traveling too fast, even if the first ground pressure is normal, the first rotational pressure may still be too high, resulting in extremely poor ice-breaking performance. To address this issue, in this embodiment, the controller is further configured to selectively issue a signal prompting the user to reduce speed based on the first and second comparison results. Specifically, if the first comparison result indicates that the first rotational pressure is greater than the upper limit of the first rotational pressure range, and the second comparison result indicates that the first ground pressure is less than the upper limit of the first ground pressure range, the signal prompting the user to reduce speed is issued.

[0072] The ice-breaking and snow-removing vehicle 100 provided in this embodiment includes a vehicle body 110, and an ice-breaking and snow-removing system is arranged on the vehicle body; the ice-breaking and snow-removing system also includes a front roller brush device 130, a scraper device 140, a rear roller brush device 150, a snowblower device 160, a spreader 170, a transfer case 180 and a full-power power take-off 190. The transfer case 180 is connected to the engine of the vehicle body 110 through the full-power power take-off 190, and is connected to the ice-breaking device 120, the front roller brush device 130, the scraper device 140, the rear roller brush device 150, the snowblower device 160 and the spreader 170, for transmitting the power output of the engine of the vehicle body 110 to the various operating devices of the ice-breaking and snow-removing system.

[0073] The front roller brush device 130 is arranged at the front position of the vehicle body 110 for clearing floating snow on the road surface; the ice-breaking device 120 and the scraping device 140 are arranged in the middle position of the vehicle body 110, the ice-breaking device 120 is used to break up ice on the road surface, and the scraping device 140 is used to scrape ice to one side of the vehicle body 110; the rear roller brush device 150 is arranged at the rear position of the vehicle body 110 for sweeping the remaining powdered snow to one side of the vehicle body 110; the spreader 170 can spread solid snow-melting agent and liquid snow-melting agent, and the spreader 170 can also heat the liquid snow-melting agent and then spray it at high pressure to the ice and snow adhesion area to obtain better ice and snow melting effect; the snow blowing device 160 can blow away the residual snow hidden under the road guardrail and other difficult-to-clear locations.

[0074] Please refer to Figure 3 and Figure 4 , Figure 3 FIG. 1 is a schematic structural diagram of a transfer case 180. Figure 4 A cross-sectional schematic view of the transfer case 180 is shown.

[0075] In this embodiment, the transfer case 180 has an input and an output. The input is connected to the engine of the vehicle 110 via a full-power power take-off 190. A clutch 187 is disposed between the input and output ends, capable of switching between an engaged and disengaged state. There are two outputs, a first output and a second output. The first output is connected to the first rotary drive member via a main pump 181, while the second output is connected to the first lifting drive member 122, the front roller brush assembly 130, the scraper assembly 140, the rear roller brush assembly 150, the snowblower 160, and the spreader 170 via a multiple pump.

[0076] Specifically, the multi-pump includes a first pump body 182, a second pump body 183 and a third pump body 184. The first pump body 182, the second pump body 183 and the third pump body 184 are connected by a bypass hydraulic pipeline. The third pump body 184 can merge with the first pump body 182 and the second pump body 183 through a merging valve provided on the bypass hydraulic pipeline to provide more flow for the first pump body 182 and the second pump body 183; in this embodiment, the first rotating drive component is connected to the main pump 181 through a hydraulic pipeline; the first lifting drive component 122 is connected to the third pump body 184 through a hydraulic pipeline.

[0077] The front roller brush device 130 is provided with a second rotary drive member connected to the first pump body 182 via a hydraulic pipeline. The second rotary drive member is actually a hydraulic motor, and the second lifting drive member is actually a hydraulic cylinder. The second rotary drive member is used to drive the front roller brush device 130 to rotate to sweep snow from the ground.

[0078] Considering that in actual applications, the front roller brush device 130 may have too little contact with the ground, resulting in poor snow-clearing effectiveness. Alternatively, the front roller brush device 130 may have too much contact with the ground, resulting in low snow-clearing efficiency and excessive energy consumption. To address this issue, the ice-breaking and snow-removing system provided in this embodiment further includes a second rotary pressure detector for detecting the second rotary pressure of the second rotary drive member.

[0079] During snow clearing, the front roller brush assembly 130 floats on the ground. If the second rotational pressure is within the corresponding preset second rotational pressure range, the bristles of the front roller brush assembly 130 are properly grounded, achieving an ideal snow clearing effect. When the second rotational pressure is less than the minimum value of the second rotational pressure range, the bristles are insufficiently grounded. The controller then issues an insufficient grounding warning signal to remind the operator to check the grounding condition of the bristles of the front roller brush assembly 130. When the second rotational pressure is greater than the maximum value of the second rotational pressure range, the bristles are excessively grounded. The controller then issues an excessive grounding warning signal to remind the operator to check the grounding condition of the bristles of the front roller brush assembly 130.

[0080] The scraper device 140 is provided with a lifting cylinder and is connected to the third pump body 184 through a pipeline; the rear roller brush device 150 is provided with a third rotating drive component and is connected to the second pump body 183 through a hydraulic pipeline. In this embodiment, the third rotating drive component is also a hydraulic motor, and the third rotating drive component is used to drive the rear roller brush device 150 to rotate to sweep snow on the ground.

[0081] Similarly, the ice breaking and snow removal system provided in this embodiment also includes a third rotary pressure detection member, which is used to detect the third rotary pressure of the third rotary drive member. During the snow clearing process, the rear roller brush device 150 floats on the ground. If the third rotary pressure is within the corresponding preset third rotary pressure range, it indicates that the amount of bristles touching the ground of the rear roller brush device 150 is appropriate, and an ideal snow clearing effect can be obtained. When the third rotary pressure is less than the minimum value of the third rotary pressure range, it indicates that the amount of bristles touching the ground is too small. At this time, the controller sends a reminder signal of insufficient grounding to remind the operator to check the grounding condition of the bristles of the rear roller brush device 150. When the third rotary pressure is greater than the maximum value of the third rotary pressure range, it indicates that the amount of bristles touching the ground is too much. At this time, the controller sends a reminder signal of excessive grounding to remind the operator to check the grounding condition of the bristles of the rear roller brush device 150.

[0082] The snowblowing device 160 is provided with a fan hydraulic motor connected to the second pump body 183 through a hydraulic pipeline, and is also provided with a lifting cylinder connected to the third pump body 184 through a hydraulic pipeline; the spreader 170 is provided with a scraper motor and a disk motor connected to the second pump body 183 through a hydraulic pipeline.

[0083] The transfer case 180 specifically includes an input flange 185, a switching cylinder 186, a clutch sleeve 187, a shift fork 188, a first gear 189, a guide rod 1891, an action detection component 1892, a first output flange 1893, a transmission gear set 1894 and a second output flange 1895. The input flange 185 is the input end, which is connected to the full-power power take-off 190 through a transmission shaft; the first output flange 1893 is the first output end, which is connected to the first gear 189 through a connecting shaft; the first gear 189 is transmission-connected to the second output flange 1895 through the transmission gear set 1894, and the second output flange 1895 is the second output end.

[0084] The clutch sleeve 187 is positioned between the input flange 185 and the first output flange 1893. The shift fork 188 is mounted on the guide rod 1891 and engages with the clutch sleeve 187. The guide rod 1891 is connected to the switching cylinder 186 and is used to drive the shift fork 188 to switch the clutch sleeve 187 between the engaged and disengaged states. An action detector 1892 is positioned opposite the end of the guide rod 1891 distal from the switching cylinder 186. It detects whether the clutch sleeve 187 has completed its state switching by measuring the distance between the guide rod 1891 and the guide rod 1891. Upon detecting that the clutch sleeve 187 has completed its state switching, a completion signal is issued.

[0085] In actual use, when the ice-breaking and snow-removing vehicle 100 is operating independently, the clutch sleeve 187 is in a disengaged state, that is, the transmission between the input flange 185 and the first and second output flanges 1893, 1895 is disconnected. When ice-breaking and snow-removing operations are required, the switching cylinder 186 drives the guide rod 1891 toward the action detection member 1892, driving the shift fork 188 to switch the clutch sleeve 187 to an engaged state, establishing transmission between the input flange 185 and the first and second output flanges 1893, 1895, thereby transmitting the power output by the vehicle body 110's engine to the ice-breaking and snow-removing system. At the end of the ice-breaking and snow-removing operation, the switching cylinder 186 drives the guide rod 1891 away from the action detection member 1892, driving the shift fork 188 to switch the clutch sleeve 187 to a disengaged state, disconnecting the transmission between the input flange 185 and the first and second output flanges 1893, 1895.

[0086] The controller is in communication with the motion detection member 1892 and is capable of receiving a completion signal from the motion detection member 1892. To prevent tooth rattling during state switching of the clutch sleeve 187, in this embodiment, after receiving a switching signal from the operator requesting the state switching of the clutch sleeve 187, the controller obtains engine state information and selectively controls the state switching of the clutch sleeve 187 based on the state information.

[0087] Specifically, the status information includes shutdown and running status. If the engine is in the shutdown state, the state of the switching clutch sleeve 187 is controlled, that is, the switching cylinder 186 is activated. If the engine is in the running state, a signal prompting the engine to shut down is issued, and the switching cylinder 186 is controlled to be inactive. In other words, the ice and snow removal vehicle 100 provided in this embodiment must ensure that the engine is in the shutdown state before the transfer case 180 is disconnected or disconnected to avoid gear knocking and improve safety.

[0088] Furthermore, after the controller controls the actuation of switching cylinder 186, if the controller receives a completion signal from actuation detection element 1892, indicating that clutch sleeve 187 has completed its state transition, i.e., successfully switched from an engaged state to a disengaged state, or vice versa, the controller issues a signal prompting the engine to start. If the controller does not receive a completion signal from actuation detection element 1892, indicating that clutch sleeve 187 has failed to switch state, the controller issues a signal indicating an abnormal engagement or disengagement, prompting the operator to inspect transfer case 180 to prevent accidents caused by direct engine starting.

[0089] In summary, the ice-breaking and snow-removing vehicle 100 provided in this embodiment has a higher degree of automation, a better ice-breaking effect, can prevent damage to the road surface, and can also prevent teeth from being knocked during the power-taking process, thus having higher safety.

[0090] This embodiment also provides a control method for an ice-breaking and snow-removing vehicle, which is applied to the aforementioned ice-breaking and snow-removing vehicle 100. Figure 5 , Figure 5 The figure shows a flow chart of the control method of the ice-breaking and snow-removing vehicle. The control method of the ice-breaking and snow-removing vehicle may include:

[0091] Step S101 : acquiring a first rotational pressure and a first ground pressure in real time.

[0092] That is, the controller receives the detection data sent by the first rotation pressure detection component in real time to obtain the first rotation pressure; the controller receives the detection data sent by the first ground pressure detection component in real time to obtain the first ground pressure.

[0093] Step S102 : performing real-time comparison between the first rotation pressure and a preset first rotation pressure range to obtain a first comparison result.

[0094] Preferably, in this embodiment, the first rotation pressure range is 1.5 MPa to 15 MPa, that is, the lower limit value of the first rotation pressure range is 1.5 MPa, and the upper limit value of the first rotation pressure range is 15 MPa.

[0095] Step S103 : performing a real-time comparison between the first ground pressure and a preset first ground pressure range to obtain a second comparison result.

[0096] Preferably, in this embodiment, the first ground pressure range is 0.5 MPa to 2 MPa, that is, the lower limit of the first ground pressure range is 0.5 MPa, and the upper limit of the first ground pressure range is 2 MPa.

[0097] It should be noted that there is no specific execution order between step S102 and step S103 , that is, step S102 and step S103 can be executed simultaneously.

[0098] Step S104 : According to at least one of the first comparison result and the second comparison result, the first lifting driving member 122 is controlled to drive the ice-breaking member 121 to rise or fall.

[0099] See also Figure 6 , Figure 6 The figure shows a flow chart of a sub-step of step S104. Step S104 may include the following sub-steps:

[0100] In sub-step S1041, when the first comparison result indicates that the first rotational pressure is greater than the upper limit value of the first rotational pressure range, and the second comparison result indicates that the first ground pressure is greater than the upper limit value of the first ground pressure range, the first lifting drive member 122 is controlled to drive the ice-breaking member 121 to rise until the first rotational pressure is within the first rotational pressure range and the first ground pressure is within the first ground pressure range.

[0101] When the first rotation pressure is greater than 15 MPa and the first ground pressure is greater than 2 MPa, it indicates that the ice-breaking element 121 encounters a ground protrusion. In order to prevent damage to the ground, the controller controls the first lifting drive element 122 to drive the ice-breaking element 121 to rise.

[0102] In sub-step S1042, when the first comparison result indicates that the first rotational pressure is less than the lower limit of the first rotational pressure range, the first lifting drive member 122 is controlled to drive the ice breaking member 121 downward until the first rotational pressure is within the first rotational pressure range.

[0103] When the first rotation pressure is less than 1.5 MPa, it indicates that the ice-breaking element 121 is under-pressure. In order to obtain a better ice-breaking effect, the controller controls the first lifting drive element 122 to drive the ice-breaking element 121 to move downward.

[0104] In sub-step S1043, when the second comparison result indicates that the first ground pressure is less than the lower limit of the first ground pressure range, the first lifting drive member 122 is controlled to drive the ice breaking member 121 downward until the first ground pressure is within the first ground pressure range.

[0105] Similarly, when the first ground pressure is less than 0.5 MPa, it also indicates that the ice-breaking element 121 is under-pressure. In order to obtain a better ice-breaking effect, the controller controls the first lifting drive element 122 to drive the ice-breaking element 121 to move downward.

[0106] Please continue reading Figure 5 The ice-breaking and snow-removing vehicle control method may further include:

[0107] Step S105 : selectively sending a signal to remind the driver to reduce the vehicle speed based on the first comparison result and the second comparison result.

[0108] See also Figure 7 , Figure 7 The figure shows a flow chart of a sub-step of step S105. Step S105 may include the following sub-steps:

[0109] In sub-step S1051, when the first comparison result indicates that the first rotational pressure is greater than the upper limit of the first rotational pressure range, and the second comparison result indicates that the first ground pressure is less than the lower limit of the first ground pressure range, a signal prompting to reduce vehicle speed is issued.

[0110] When the first rotation pressure is greater than 15 MPa but the first ground pressure is less than 2 MPa, it indicates that the vehicle speed is too fast. The controller sends a signal to remind the operator to reduce the speed.

[0111] Please continue reading Figure 5 The ice-breaking and snow-removing vehicle control method may further include:

[0112] Step S106: After obtaining the switching signal requesting to switch the state of the clutch sleeve 187, the state information of the engine is obtained.

[0113] When the operator presses the power take-off button, the controller receives a switching signal requesting to switch the state of the clutch sleeve 187. At this time, the controller obtains the state information of the engine, which includes the shutdown state and the running state.

[0114] Step S107 , selectively controlling the switching state of the clutch sleeve 187 according to the state information.

[0115] See also Figure 8 , Figure 8 The figure shows a flow chart of a sub-step of step S107. Step S107 may include the following sub-steps:

[0116] Sub-step S1071 , if the engine is in the shutdown state, control the switching state of the clutch sleeve 187 .

[0117] Sub-step S1072: If the engine is in the running state, a signal is sent to prompt to shut down the engine.

[0118] It is understandable that before the transfer case 180 takes off power or is disconnected, it is necessary to ensure that the engine is in a stopped state to avoid gear knocking and improve safety.

[0119] Please continue reading Figure 5 The ice-breaking and snow-removing vehicle control method may further include:

[0120] Step S108: After controlling the state of the clutch sleeve 187 and obtaining a completion signal, a signal prompting to start the engine is issued.

[0121] After the controller controls the switching cylinder 186 to actuate, if the controller receives a completion signal from the actuation detection element 1892, indicating that the clutch sleeve 187 has completed the state switching, that is, successfully switched from the engaged state to the disengaged state, or successfully switched from the disengaged state to the engaged state, the controller then issues a signal prompting the engine to start, and the engine can start normally.

[0122] Step S109 : After controlling the state of the clutch sleeve 187 to switch, if no completion signal is obtained, a signal to remind of abnormal engagement or abnormal disengagement is issued.

[0123] After the controller controls the switching cylinder 186 to operate, the controller does not receive the completion signal from the action detection component 1892, indicating that the clutch sleeve 187 state switching has failed. At this time, the controller sends a signal to remind the operator of abnormal engagement or abnormal disengagement, reminding the operator to inspect the transfer case 180 to prevent the engine from starting directly and causing an accident.

[0124] In fact, the ice-breaking and snow-removing vehicle control method provided in this embodiment further includes the following steps:

[0125] Step S110, obtaining the second rotation pressure in real time;

[0126] Step S111, comparing the second rotation pressure with a preset second rotation pressure range in real time to obtain a third comparison result;

[0127] Step S112 , selectively sending a signal to remind the user to check the grounding condition of the bristles of the front roller brush device 130 according to the third comparison result.

[0128] The second rotational pressure detector detects the second rotational pressure of the front roller brush assembly 130 and transmits the detection result to the controller, which then compares the second rotational pressure with the second rotational pressure range in real time. If the second rotational pressure is within the second rotational pressure range, it indicates that the bristles of the front roller brush assembly 130 are properly grounded, achieving an ideal snow-clearing effect.

[0129] When the second rotational pressure is less than the minimum value of the second rotational pressure range, it indicates that the amount of bristles contacting the ground is too small. In this case, the controller issues a warning signal indicating that the amount of bristles contacting the ground is insufficient, prompting the operator to check the grounding condition of the bristles of the front roller brush device 130. When the second rotational pressure is greater than the maximum value of the second rotational pressure range, it indicates that the amount of bristles contacting the ground is excessive. In this case, the controller issues a warning signal indicating that the amount of bristles contacting the ground is excessive, prompting the operator to check the grounding condition of the bristles of the front roller brush device 130.

[0130] In addition, the ice-breaking and snow-removing vehicle control method provided in this embodiment further includes the following steps:

[0131] Step S113, obtaining the third rotation pressure in real time;

[0132] Step S114, comparing the third rotation pressure with a preset third rotation pressure range in real time to obtain a fourth comparison result;

[0133] Step S115 , selectively sending a signal to remind the user to check the grounding condition of the bristles of the rear roller brush device 150 according to the fourth comparison result.

[0134] The third rotational pressure detector detects the third rotational pressure of the rear roller brush assembly 150 and transmits the detection result to the controller, which then compares the third rotational pressure with the third rotational pressure range in real time. If the third rotational pressure is within the third rotational pressure range, it indicates that the bristles of the rear roller brush assembly 150 are properly grounded, achieving an ideal snow-clearing effect.

[0135] When the third rotational pressure is less than the minimum value of the third rotational pressure range, it indicates that the amount of bristles contacting the ground is too low. The controller then issues a warning signal indicating that the bristles of the rear roller brush device 150 are not contacting the ground, prompting the operator to check the contact condition of the bristles of the rear roller brush device 150. When the third rotational pressure is greater than the maximum value of the third rotational pressure range, it indicates that the amount of bristles contacting the ground is too high. The controller then issues a warning signal indicating that the bristles of the rear roller brush device 150 are contacting the ground, prompting the operator to check the contact condition of the bristles of the rear roller brush device 150.

[0136] In summary, the ice-breaking and snow-removing vehicle control method provided in this embodiment has a higher degree of automation, can achieve better snow-clearing and ice-breaking effects, can prevent damage to the road surface, and can also prevent teeth from being knocked during the power-taking process, thus having higher safety.

Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible.
