Description

Technical Field

[0001] This invention relates to the field of electric vehicle battery swapping, and more particularly to an auxiliary battery swapping device for a battery swapping box. Background Technology

[0002] With the country's increasing emphasis on environmental protection, electric vehicles have become a development trend in recent years, replacing gasoline vehicles. At the same time, more and more heavy trucks are starting to use batteries as a power source. However, due to factors such as the large power consumption and long charging time of heavy trucks, the economic efficiency and scalability of electric heavy trucks are limited. Therefore, heavy trucks with quick battery swapping capabilities are more widely used.

[0003] Currently, in the field of battery swapping for electric heavy-duty trucks, battery boxes adopt a quick-replacement structure, allowing replacement to be completed within dedicated battery swapping stations. With the aid of a dedicated swapping device, the discharged battery box is removed and placed on the charging station, while the charged battery box is installed onto the electric heavy-duty truck. During battery swapping, especially when using a side-grabbing method, existing technologies typically involve directly removing the discharged battery box using a hook without clamping or securing it. This makes the battery box prone to shaking during transfer, leading to collision damage and significant safety hazards. Furthermore, due to prolonged driving, the power interface of heavy-duty trucks may become loose. If not inspected and repaired promptly, this can result in poor battery box contact. Additionally, the accumulation of dust on the battery box surface reduces heat dissipation, shortening the lifespan of the power battery. Summary of the Invention

[0012] As an improvement to the above scheme, one side of the wedge block is set as an inclined surface.

[0013] As an improvement to the above solution, the second elastic element is a spring.

[0014] As an improvement to the above solution, the cleaning assembly includes a base frame, a second housing, a cover, a fan, an air blowing plate, a first electric slide rail, a first electric slider, a door panel, a fourth connecting plate, a first panel, a second electric slide rail, a second electric slider, a fifth connecting plate, a second panel, a first brush plate, and a second brush plate; the base frame is fixedly connected to the upper side of the two rear drive blocks; the second housing is mounted on the upper side of the base frame; the cover is fixedly connected to the middle of the upper side of the second housing; the fan is fixedly connected to the middle of the upper side of the second housing; the fan is located inside the cover; an air blowing plate is fixedly connected to the middle of the left side and the middle of the right side inside the second housing; two air blowing plates are fixedly connected to the front upper side of the second housing.

[0015] The beneficial effects of this invention are as follows: During the movement of the second connecting plate, the second clamping plate pushes the power interface. When the power interface is not loose, the second clamping plate slides to the right on the third connecting plate, and the contact post moves synchronously with the second clamping plate. The first elastic element is compressed, and the contact post squeezes the pressure sensor, causing the pressure sensor parameter to increase. When the power interface is loose, the second clamping plate pushes the power interface to shake, but the parameter on the pressure sensor does not change. Thus, based on the change in the pressure sensor parameter, it can be known which power interface is loose, allowing the operator to repair the power interface in time and avoid poor contact between the power interface and the battery box, which could reduce the contact area, cause overheating of the connector, and lead to safety accidents. At the same time, the scanner will scan the power interface to detect whether the connecting post or the power interface itself has deformed, further preventing poor contact of the power interface.

[0016] The present invention also uses four hooks to contact the battery box, and with the cooperation of the third clamping plate, the battery box is clamped and fixed. This avoids the situation in the prior art, where the battery box is usually lifted directly from the first base and then transferred without clamping and fixing it. This makes the battery box very easy to shake during the transfer, resulting in collision damage to the battery box and posing a significant safety hazard.

[0017] The present invention also achieves dust cleaning of the entire battery box through the action of the first baffle, the second baffle, the first brush plate and the second brush plate, which improves the heat dissipation of the battery box and increases the service life of the power battery.

[0046] When using this battery swapping box auxiliary battery swapping device, the first base 6 is first fixed to the chassis beam of the heavy truck, so that the first base 6 and the heavy truck form a stable whole, which helps to improve the load-bearing and fixing effect of the battery box 5. When the battery box 5 needs to be swapped, the driver drives the heavy truck into the designated position of the battery swapping station, that is, the battery box 5 is located on the left side of the first box 210. At this time, the locking mechanism on the first base 6 is opened, so that the battery box 5 is not locked. At the same time, the camera 401 is controlled to detect and scan the battery box 5. Since the heavy truck is long, some drivers may tilt it when parking. At this time, the camera 401 detects the tilt. The acquired data controls the third electric push rod 403 to rotate the second base 405, which in turn drives the fixing block 404 to rotate on the first housing 210. This ensures that the rotation angle of the fixing block 404 matches the tilt angle of the battery box 5. The bracket 406, the fourth electric push rod 407, the transmission column 408, the disc 409, the wedge block 410, the third clamping plate 411, the connecting column 412, the second elastic element 413, and the hook 414 rotate synchronously with the fixing block 404. This facilitates the hook 414 in clamping and fixing the battery box 5 and prevents the battery box from being damaged when the hook 414 moves. The five hooks 414 are limited, then the power motor 207 is controlled to make the lead screw 208 rotate clockwise from right to left. The lead screw 208 drives the first connecting plate 209 to move to the left on the second guide rail 206. The first housing 210, counterweight 211, camera 401 and clamping assembly move synchronously with the first connecting plate 209, and then the four hooks 414 will enter the port of the battery box 5. Then the fourth electric push rod 407 is controlled to push the transmission column 408 to the left. The disc 409, wedge block 410 and third clamping plate 411 move synchronously with the transmission column 408, and then the wedge block 410 moves to the left. The 0 will push the hook 414 to slide outward on the connecting post 412, causing the four hooks 414 to open outward, the second elastic element 413 to be compressed, and the four hooks 414 to contact the battery box 5. With the cooperation of the third clamping plate 411, the battery box 5 is clamped and fixed. This avoids the situation in the prior art where the battery box 5 is usually lifted directly from the first base 6 and then transferred without clamping and fixing it. This makes the battery box 5 very easy to shake during the transfer, resulting in collision damage to the battery box 5 and posing a great safety hazard.

[0047] After the battery box 5 is clamped and fixed, the four hydraulic cylinders 202 are controlled to move the third support plate 204 upward. The battery box 5, guide plate 205, second guide rail 206, power motor 207, lead screw 208, first connecting plate 209, first housing 210, counterweight 211, pushing assembly, detection assembly, camera 401, and clamping assembly move synchronously with the third support plate 204. The protective cover 203 is stretched, and the battery box 5 will detach from the first base 6. When the second connecting plate 304 moves above the base plate 7, the four hydraulic cylinders 202 are controlled to stop the third support plate 204 from moving. Next, the first electric push rod 302 is controlled to slide the second connecting plate 304 to the left on the fourth support plate 303. The scanner 305 and the detection component move synchronously with the second connecting plate 304, and then the second electric push rod 306 is positioned above the power interface 8. At this time, the second electric push rod 306 is controlled to move the third connecting plate 307 downward. The first clamping plate 308, the second clamping plate 309, the contact post 310, the first elastic element 311, the fifth support plate 312, and the pressure sensor 313 move synchronously with the third connecting plate 307, so that the first clamping plate 308 and the second clamping plate 309 will be in contact with the power interface 8. The first electric push rod 302 is then controlled to move the second connecting plate 304 to the left. During the movement of the second connecting plate 304, the second clamping plate 309 pushes the power interface 8. When the power interface 8 is not loose, the second clamping plate 309 slides to the right on the third connecting plate 307. The contact post 310 moves synchronously with the second clamping plate 309, compressing the first elastic element 311. This causes the contact post 310 to squeeze the pressure sensor 313, increasing the pressure sensor parameter. When the power interface 8 is loosened, the second clamping plate 309... The board 309 will push the power interface 8 to vibrate, and the parameters on the pressure sensor 313 will not change. In this way, the operator can know which power interface 8 is loose based on the change in the parameters of the pressure sensor 313, so that the operator can repair the power interface 8 in time and avoid poor contact between the power interface 8 and the battery box 5, which would reduce the contact area, cause the connector to overheat, and lead to safety accidents. At the same time, the scanner 305 will scan the power interface 8 to detect whether the fixing post on the power interface 8 or the power interface 8 has been deformed, further preventing the occurrence of poor contact of the power interface 8.

[0048] After the power interface 8 completes the detection, the second electric push rod 306 is controlled to move the third connecting plate 307 upwards to reset, and the first clamping plate 308 and the second clamping plate 309 disengage from the power interface 8. Then, the first electric push rod 302 is controlled to move the second connecting plate 304 to the right to reset. Then, the electric turntable 4 is controlled to rotate the second support plate 201 90 degrees clockwise from top to bottom. The battery box 5, hydraulic cylinder 202, protective cover 203, third support plate 204, guide plate 205, second guide rail 206, power motor 207, lead screw 208, first connecting plate 209, first housing 210, counterweight 211, pushing assembly, detection assembly, camera 401, and clamping assembly rotate synchronously with the second support plate 201, thereby causing the battery box to rotate. Positioned in front of the second housing 502, the two rear drive blocks 2 are controlled to move the base frame 501 forward. The cover 503, fan 504, air blowing plate 505, first electric slide rail 506, first electric slider 507, door panel 508, fourth connecting plate 509, first panel 510, second electric slide rail 511, second electric slider 512, fifth connecting plate 513, second panel 514, first brush plate 515, and second brush plate 516 move synchronously with the base frame 501, thus allowing the battery box 5 to enter the second housing 502. Simultaneously, the hydraulic cylinder 202 moves the third support plate 204 downward, placing the battery box 5 on the second housing 502. Then, the two rear drive blocks 2 are controlled to move the base frame 501 backward. The device is moved and reset. Then, the first electric slide rail 506 is controlled to make the first electric slider 507 slide downwards. The door panel 508, the fourth connecting plate 509, the first panel 510, and the second brush plate 516 move synchronously with the first electric slider 507. The first panel 510 and the second brush plate 516 then contact the battery box 5. Under the action of the first panel 510 and the second brush plate 516, the dust on the surrounding surface of the battery box 5 is cleaned. During the downward movement of the door panel 508, the fan 504 is simultaneously controlled to operate. Under the action of the fan 504, the scraped dust is sucked into the cover 503 and then enters the peripheral collection box through the connecting pipe on the cover 503. Simultaneously, the air blowing plate 505 is controlled to blow out cold air, allowing the battery box 5 to... To cool down the battery box 5 and prevent overheating during subsequent charging, which could reduce charging efficiency, the second electric slide rail 511 is controlled to move the second electric slider 512 forward. The fifth connecting plate 513, the second plate cover 514, and the first brush plate 515 move synchronously with the second electric slider 512, thus cleaning the dust on the top of the battery box 5. This achieves dust cleaning of the entire battery box 5, improving heat dissipation and increasing the lifespan of the power battery. While cleaning the battery box 5, the electric turntable 4 is simultaneously controlled to rotate the second support plate 201 90 degrees clockwise from top to bottom, which is coordinated with the movement of the two front drive blocks 2.Positioning the clamping assembly next to the fully charged battery box 5, the aforementioned clamping and fixing steps for the battery box 5 are repeated to clamp and fix the fully charged battery box 5. Once the fully charged battery box 5 is clamped and fixed, the power motor 207 is controlled to rotate the lead screw 208 counterclockwise from right to left. As the lead screw 208 rotates, the first connecting plate 209 slides to the right on the lead screw 208. The first housing 210, counterweight 211, battery box 5, camera 401, and clamping assembly move synchronously with the first connecting plate 209, thereby positioning the battery box 5 above the guide plate 205. Then, the electric turntable 4 is controlled to move the first... The second support plate 201 rotates 180 degrees clockwise from top to bottom to reset, coordinating with the movement of the two front drive blocks 2, so that the fully charged battery box 5 is positioned on one side of the first base 6. Then, with the rotation of the lead screw 208, the fully charged battery box 5 is positioned directly above the first base 6. Next, the hydraulic cylinder 202 is controlled to move the third support plate 204 downward, thereby completing the replacement of the battery box 5. After the heavy truck with the battery box 5 replaced, the driver can drive the heavy truck out of the battery swapping station. At the same time, the clamping assembly removes the cleaned battery box 5 from the second housing 502, and then places the battery box 5 in an available charging position for charging.
