[0034] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0035] Example 1

[0036] Reference Figure 1This embodiment provides an electric drive cooling system for a driverless wide-body dump truck with a driverless cab, including a cooling assembly 100 and an air intake assembly 200.

[0037] The cooling assembly 100 includes a first cooling circuit 101, a second cooling circuit 102, and a cooler 103. The first cooling circuit 101 and the second cooling circuit 102 are respectively connected to the cooler 103, and the first cooling circuit 101 and the second cooling circuit 102 are connected in parallel.

[0038] The air intake assembly 200 and the cooler 103 cooperate with the air intake assembly 200. The air intake assembly 200 includes a conical air inlet 201, a ventilation component 202, a spray component 203, a rotating component 204 and a scraper 205. The conical air inlet 201 is connected to the ventilation component 202. The spray component 203 and the rotating component 204 are installed on the ventilation component 202. The rotating component 204 cooperates with the spray component 203 and the scraper 205 cooperates with the rotating component 204.

[0039] The first cooling circuit 101 includes a first electronic controller 101a, a first motor 101b, and a second motor 101c. One end of the first electronic controller 101a is connected to the cooler 103 through a pipe, and the other end is connected to the first motor 101b and the second motor 101c through a pipe.

[0040] The second cooling circuit 102 includes a second electronic controller 102a, a third electronic controller 102b, a multi-function electronic controller 102c, and a third motor 102d. One end of the second electronic controller 102a is connected to the cooler 103 through a pipe, and the other end is connected to the multi-function electronic controller 102c through a pipe. The multi-function electronic controller 102c is connected to the third electronic controller 102b through a pipe. The third electronic controller 102b is connected to the third motor 102d through a pipe. The third motor 102d is connected to the cooler 103 through a pipe.

[0043] The cooling fan is controlled by an independent ATS intelligent cooling unit for auxiliary cooling and is not connected to the motor. When the vehicle power demand is low and the electric drive cooling requirements are high, the motor does not need to passively increase its speed to ensure the speed of the cooling fan, which can effectively reduce the power battery consumption.

[0044] By optimizing the layout space and rationally allocating the cooling pipe routing during use, the cooling problem of 3 motors plus 3 motor controllers plus an all-in-one unit was solved.

[0054] The placement plate 202b-5 is provided with inclined slots 202b-51. Multiple inclined slots 202b-51 are provided to prevent flying stones from flying out of the inclined slots 202b-51 and damaging the cooler 103.

[0058] The 204d sweeping disc has multiple 204d-1 sweeping brushes on its side.

[0059] The spraying component 203 includes a water tank 203a, an extrusion plate 203b, and a pulling rod 203c. The water tank 203a is installed in the mounting groove 202b-6. The extrusion plate 203b is slidably connected to the water tank 203a. One end of the pulling rod 203c is rotatably connected to the extrusion plate 203b, and the other end is rotatably connected to the fixed pull rod 204b-1.

[0060] Furthermore, the extruded plate 203b is made of rubber.

[0061] Water tank 203a includes a water cavity 203a-1, a squeezing groove 203a-2, an inlet valve 203a-3, an outlet valve 203a-4, and a spray pipe 203a-5. The water cavity 203a-1 is located inside the water tank 203a. The squeezing groove 203a-2 is located at the lower end of the water tank 203a. The spray pipe 203a-5 is located on the side of the water tank 203a. The inlet valve 203a-3 is located inside the water cavity 203a-1 and communicates with the squeezing groove 203a-2, allowing water to exit. Valve port 203a-4 is located inside the extrusion groove 203a-2 and communicates with the spray pipe 203a-5. One-way valves are installed on the inlet valve port 203a-3 and the outlet valve port 203a-4. Water in the water chamber 203a-1 can only flow into the extrusion groove 203a-2 through the inlet valve port 203a-3. Water in the extrusion groove 203a-2 can only flow into the spray pipe 203a-5 and be sprayed out from the atomizing valve on the spray pipe 203a-5. There are two spray pipes 203a-5.

[0062] The scraper 205 includes a movable hole 205a and an arc-shaped block 205b. The movable hole 205a is located on the side of the scraper 205. A movable connecting post 205a-1 is provided inside the movable hole 205a. The arc-shaped block 205b is rotatably connected to the movable connecting post 205a-1. The arc-shaped block 205b is placed inside the first spiral groove 204c-1.

[0063] The scraper 205 also includes a side protrusion 205c and an inclined block 205d. The side protrusion 205c is disposed on the side of the scraper 205, and the inclined block 205d is rotatably connected to the side protrusion 205c. Multiple side protrusions 205c are provided.

[0064] A torsion spring is provided at the rotatable connection between the inclined block 205d and the side protrusion 205c to keep the inclined block 205d parallel to the side protrusion 205c.

[0065] The side protrusions 205c are designed with one long and one short on the two sides of the scraper 205 to facilitate their engagement with the gear 202b-42.

[0066] When the vehicle is moving, the air enters the inclined pipe 202a from the conical air inlet 201 and then enters the cooler 103 through the filter box 202b. Because the inclined pipe 202a is inclinedly connected to the filter box 202b, and the inclined panel 202a-1 inside the inclined pipe 202a is also inclined, larger dust or flying stones will be blocked by the inclined pipe 202a and the internal inclined panel 202a-1 and then roll into the dust discharge trough 202b-3 and onto the dust discharge shaft 202b-4.

[0067] The air entering through the conical air inlet 201 is gathered and blown out by the inclined panel 202a-1, causing the fan blades on the rotating fan 204b to rotate. The rotating shaft 204c and the cleaning disc 204d rotate accordingly. The cleaning brush 204d-1 cleans the dust on the filter screen 202b-2, and the swept dust falls onto the dust discharge shaft 202b-4. The fixed pull rod 204b-1 rotates with the rotating fan 204b, driving the pulling rod 203c to move. The pulling rod 203c causes the extrusion plate 203b to move up and down in the extrusion groove 203a-2. Water enters the extrusion groove 203a-2 from the water chamber 203a-1 through the water inlet valve 203a-3, enters the spray pipe 203a-5 through the water outlet valve 203a-4, and finally is sprayed out through the atomizing valve to treat the dust in the air flowing in the filter cavity 202b-1.

[0068] While rotating, the rotating shaft 204c drives the inclined block 205d to slide crosswise in the first spiral groove 204c-1 and the second spiral groove 204c-2, so that the scraper 205 moves back and forth in the filter inner cavity 202b-1 to scrape and clean the dust on the inner wall of the filter inner cavity 202b-1.

[0069] When the scraper 205 moves to one end of the filter inner cavity 202b-1, the inclined block 205d contacts the gear 202b-42 and pushes the gear 202b-42 to rotate. The dust discharge shaft 202b-4 rotates accordingly. The dust on the dust collection plate 202b-41 is discharged from the lower end of the dust discharge groove 202b-3 at the same time as the dust discharge shaft 202b-4 rotates. When the scraper 205 moves to the other end of the filter inner cavity 202b-1, the inclined block 205d contacts the gear 202b-42 but does not push the gear 202b-42 to rotate. Instead, it flips upward.

[0070] As the scraper 205 moves to the other end and away, the inclined block 205d located on the other side of the scraper 205 repeats the above action.

[0071] When the scraper 205 moves back and forth in the filter cavity 202b-1, the two dust discharge shafts 202b-4 will gradually rotate one counterclockwise and the other clockwise, and both will rotate one revolution to prevent dust from accumulating on the dust collection plate 202b-41.

[0072] This device can continuously cool the electrically driven equipment to prevent it from overheating, and it also has an automatic dust cleaning function to prevent the cooling equipment from becoming clogged.
