[0040] In order to improve the safety of vehicle driving, the present technical solution proposes a vehicle-mounted road surface processing device, comprising:

[0041] The housing 100 is disposed at the bottom of the vehicle and at one side of the wheel close to the front of the vehicle;

[0042] The obstacle suction component 200 has a connection end and a suction end. The connection end is rotatably connected to the housing 100 to swing closer to or away from the ground. The suction end is arranged on a side of the connection end facing the ground to suction obstacles.

[0043] In the technical solution of the present invention, a shell 100 is arranged at the bottom of the vehicle, and the shell 100 is arranged on the side of the wheel close to the front of the vehicle. In addition, an obstacle suction component 200 is arranged on the shell 100, and the obstacle suction component 200 is rotatably connected to the shell 100 through a connecting end, so that the obstacle suction component 200 can be swung close to or away from the ground. In this way, when in use, the suction end can be swung close to the ground and absorb obstacles such as nails, ensuring that the road surface on which the wheel has traveled is cleaned in advance, thereby preventing the occurrence of tire punctures during vehicle driving, thereby improving the safety of vehicle driving; in addition, when not in use, the obstacle suction component 200 can be swung to fit with the bottom of the vehicle, which can protect the obstacle suction component 200 from bumps and improve the safety of use.

[0044] like Figure 1 and Figure 2 In one embodiment of the present invention, the vehicle-mounted road surface treatment device includes a housing 100, the housing 100 is fixed to the bottom of the vehicle, and a vehicle-mounted road surface treatment device is arranged on one side of each wheel close to the front of the vehicle, and an obstacle suction component 200 is arranged on the housing 100, and the obstacle suction component 200 has a relative connecting end and a suction end, wherein the connecting end is rotatably connected to the housing 100 by a hinge, and the suction end can swing between a position in contact with the bottom of the vehicle and a position perpendicular to the ground by rotation, and when the suction end is in a position perpendicular to the ground and close to the ground, the suction end can suck obstacles such as nails on the ground, so as to ensure that the area where the wheel passes through The area is cleaned, thereby preventing the occurrence of tire punctures; in the present embodiment, the obstacle suction component 200 may adopt the following structural form: for example, the obstacle suction component 200 may include a negative pressure device and a straw connected to the negative pressure device, the negative pressure device is installed on the shell 100, and the straw is rotatably connected to the shell 100 through a hinge. In addition, a motor may be provided, and the motor shaft of the motor is connected to one end of the straw connected to the hinge to drive the straw to rotate. When the straw is perpendicular to the ground, the negative pressure device can generate negative pressure in the straw, and the obstacles on the ground are sucked into the straw to achieve cleaning. The above scheme is only an example, and the obstacle suction component 200 in the present embodiment may not be limited to this.

[0045] Figure 1 and Figure 2Another structural form of the obstacle suction component 200 is shown. In this embodiment, the obstacle suction component 200 includes: a driving component 210, which is arranged on the housing 100; a fixing base 220, and the driving component 210 is drivingly connected to the fixing base 220 to drive the fixing base 220 to rotate relative to the housing 100; a magnetic suction rod 230, which is arranged on the fixing base 220 and extends away from the fixing base 220. Among them, the driving component 210 can be a motor, the motor shell of the motor is fixed on the outer shell 100, the motor shaft of the motor can extend along the width direction of the vehicle, the fixing seat 220 can be a columnar structure, one end of the fixing seat 220 is fixed on the motor shaft, and the fixing seat 220 is directly driven to swing by the rotation of the motor shaft. A cavity with an opening is set on the end of the fixing seat 220 away from the motor shaft, and a magnetic rod 230 is set in the cavity. In order to facilitate the implementation of the solution, the magnetic rod 230 can be made of permanent magnet material. One end of the magnetic rod 230 is connected to the fixing seat 220, and the other end extends out of the above-mentioned cavity from the opening. When working, the driving component 210 drives the opening of the fixing seat 220 toward the ground. At this time, the magnetic rod 230 is vertically downward. During the driving of the vehicle, the magnetic rod 230 will first pass through the road surface that the wheel will pass through. Obstacles with ferromagnetism such as iron nails or iron sheets on the road surface can be adsorbed on the magnetic rod 230, thereby preventing the tire from running over the obstacle and reducing the risk of puncture.

[0046] like Figure 1 and Figure 2 In order to ensure that the magnetic rod 230 can still normally absorb obstacles after long-term use, in one embodiment of the present invention, the obstacle absorption component 200 also includes a cleaning component 240, which is movably arranged on the shell 100. The cleaning component 240 moves along the axial direction of the magnetic rod 230 to absorb and remove obstacles on the outer wall of the magnetic rod 230.

[0047] In this embodiment, the cleaning component 240 is movably mounted on the housing 100 and can reciprocate along the axial direction of the magnetic rod 230. After the magnetic rod 230 completes a period of adsorption, the cleaning component 240 can clean the outer wall of the magnetic rod 230 to remove obstacles such as iron nails and iron sheets adsorbed thereon, thereby ensuring that the adsorption surface of the magnetic rod 230 is always kept clean to maintain the best adsorption effect. The cleaning component 240 can adopt a variety of structural forms. For example, a brush or scraper driven by a cylinder to move up and down can be arranged in the cavity. The brush or scraper moves closely against the surface of the magnetic rod 230 to scrape off obstacles on the surface of the magnetic rod 230. A container can be arranged below the brush or scraper, and the scraped obstacles can fall into the container and be collected. By setting the cleaning component 240, the cleanliness of the magnetic rod 230 can be guaranteed, thereby ensuring the effect of obstacle absorption.

In this embodiment, the cleaning component 240 includes: a storage shell 241, which is arranged on the outer shell 100; a negative pressure generator 242, which is arranged on the outer shell 100, and the negative pressure generator 242 is connected to the storage shell 241 to form a negative pressure in the storage shell 241 and the adsorption tube 244; a first driving member 243, having a first fixed end and a first driving end connected to the first fixed end, the first fixed end is connected to the fixed seat 220, and the first driving end is drivingly connected to the other end of the adsorption tube 244 to drive the adsorption tube 244 to move axially along the magnetic suction rod 230; the adsorption tube 244 is arranged at the first driving end, one end of the adsorption tube 244 is connected to the storage shell 241, and the other end is arranged toward the outer peripheral wall of the magnetic suction rod 230. Among them, the storage shell 241 can be a box structure, and the storage shell 241 can be installed on the outer shell 100 in a detachable manner such as screw connection or clamping. The storage shell 241 is used to store obstacles sucked by the cleaning component 240, and the detachable manner is convenient for cleaning when the storage shell 241 is full; in addition, a negative pressure generator 242 is arranged on the outer shell 100, and the negative pressure generator 242 can adopt a device such as a negative pressure fan. The negative pressure generator 242 can be connected with the storage shell 241 through a pipeline. In order to prevent foreign matter from entering the negative pressure generator 242, a filter can be set at the place where the pipeline and the storage shell 241 are connected to allow only air flow to pass; the first driving member 243 can be a cylinder, an electric push rod or a hydraulic cylinder, which has a piston and a cylinder body, the cylinder body constitutes a first fixed end, the piston constitutes a first driving end, and the piston moves parallel to the magnetic suction rod 230. The suction tube 244 can be a hard tube, and the suction tube 244 has two parts, one part of which extends parallel to the magnetic suction rod 230, and the other part extends toward the magnetic suction rod 230. The part of the suction tube 244 parallel to the magnetic suction rod 230 is fixed on the first driving end and is connected to the storage shell 241 through a hose. When the negative pressure generator 242 is working, a negative pressure can be formed in the suction tube 244 and the storage shell 241. The part of the suction tube 244 facing the magnetic suction rod 230 can generate suction. By adjusting the suction, obstacles on the magnetic suction rod 230 can be sucked into the suction tube 244 and finally enter the storage shell 241; in addition, the first driving end can synchronously move along the axial direction of the magnetic suction rod 230, so that the suction tube 244 is relative to different positions of the magnetic suction rod 230, so as to achieve the cleaning of the entire axial area of ​​the magnetic suction rod 230.

[0049] like Figure 2In one embodiment of the present invention, a suction port is provided on the suction tube 244 at one end facing the magnetic suction rod 230, and the suction port extends in an arc shape around the outer wall of the magnetic suction rod 230; in order to ensure the suction effect, the diameter of the suction tube 244 at one end facing the magnetic suction rod 230 can be enlarged, and the part with the enlarged diameter forms a suction port towards one end of the magnetic suction rod 230, and the edge of the suction port is arranged in an arc shape, so that the suction port can extend around the outer wall of the magnetic suction rod 230, so that the suction force can act on a larger area of ​​the outer wall of the magnetic suction rod 230, thereby improving the suction effect.

[0050] In one embodiment of the present invention, the magnetic rod 230 includes: a rod body, one end of which is connected to the fixing seat 220, and the other end of which extends away from the fixing seat 220; and a magnet, which is arranged on the outer peripheral wall of the end of the rod body away from the fixing seat 220. The rod body is a long rod-shaped structure, and the magnet is arranged on the outer side wall of the end of the rod body away from the fixing seat 220. The magnet can be fixed to the rod body by bonding, which can simplify the structure of the magnetic rod 230 while reducing the processing difficulty and manufacturing cost.

[0051] like Figure 2 In one embodiment of the present invention, the obstacle suction component 200 further includes a second driving member 250, the second driving member 250 has a second fixed end and a second driving end connected to the second fixed end, the second fixed end is connected to the fixing seat 220, the second driving end moves closer to or away from the fixing seat 220, and the magnetic suction rod 230 is arranged at the second driving end.

[0052] like Figure 1 In one embodiment of the present invention, the vehicle-mounted road surface treatment device also includes a spray component 300, which is disposed on the housing 100. A nozzle is provided on the spray component 300 facing the ground. The spray component 300 sprays a snow-melting medium onto the ground through the nozzle. The snow-melting medium can be hot water or a snow-melting agent. This can reduce the risk of tire slippage and further improve driving safety.

[0053] Figure 1 and Figure 2A structural form of a spray assembly 300 is shown. In this embodiment, the spray assembly 300 includes: a liquid storage shell 310, which is arranged on the outer shell 100, and the liquid storage shell 310 is used to store snow melting medium; a driving pump 320, which is provided with an inlet and an outlet, and the inlet is connected to the liquid storage shell 310; a nozzle 330, which is arranged at the connecting end, and the nozzle is formed on the nozzle 330, and the nozzle 330 is connected to the outlet.
