Description

Technical Field

[0001] The utility model relates to the technical field of wire-controlled chassis, and in particular to an automatic driving heavy-duty manned wire-controlled chassis. Background Art

[0002] my country is at the turning point of the transformation from functional cars to smart cars, and numerous emerging technologies have made great progress. Self-driving cars, also known as driverless cars, computer-driven cars, or wheeled mobile robots, are smart cars that achieve unmanned driving through computer systems. It has a history of several decades in the 20th century and is close to practical application in the early 21st century. The wire-controlled chassis consists of five major systems: steering, braking, shifting, throttle, and suspension. The wire-controlled system eliminates some bulky and low-precision pneumatic, hydraulic, and mechanical connections, and replaces them with sensors, control units, and electromagnetic actuators driven by electrical signals. Therefore, it has the advantages of compact structure, good controllability, and fast response speed. The implementation process of wire-controlled technology: The sensor converts the driver's control instructions into electrical signals and transmits them to the controller. The controller analyzes the signal and sends the instructions to the actuator, and finally the functional device implements the target instructions.

[0003] Self-driving heavy-duty passenger vehicles are mostly powered by batteries. Multiple assembled batteries are installed in a wire-controlled chassis. During the operation of the vehicle, the operation of multiple groups of batteries will generate a large amount of heat energy. Therefore, good heat dissipation effect also directly affects the operation of self-driving heavy-duty passenger vehicles.

[0004] For example, a new energy vehicle wire-controlled chassis proposed in 202320630363.8 realizes heat exchange for the battery through the structural structure of the battery module unit itself. Compared with the existing method of using a motor plus a fan, it is more energy-saving and environmentally friendly, and at the same time, it improves the heat exchange effect of the battery module unit. However, the use of ventilation holes to circulate air for heat dissipation results in the opening of multiple flow holes on the wire-controlled chassis. On rainy days, rainwater will enter the wire-controlled chassis through the flow holes, causing damage to the battery pack, and it is also easy for dust to enter through the flow holes, which reduces the life of the battery pack. Therefore, a new type of autonomous driving heavy-duty manned wire-controlled chassis is proposed. Utility Model Content

[0027] The heat dissipation mechanism 3 includes an installation box 301, the front and back sides of the disk body 1 are fixedly installed with the installation box 301, the side of the installation box 301 away from the disk body 1 is fixedly installed with a filter cover, the bottom of the installation box 301 is fixedly installed with a heat dissipation box 302, the interior of the heat dissipation box 302 is filled with heat dissipation water, a connecting pipe 303 is fixedly installed on the side of the installation box 301 close to the disk body 1, a sealing plate 304 is fixedly installed on the interior of the heat dissipation box 302, an air supply tube 305 is fixedly installed on the interior of the heat dissipation box 302, a delivery tube 306 is plugged into the air supply tube 305, a water supply tube 307 is fixedly installed on the side of the heat dissipation box 302 close to the disk body 1, a sealing frame 308 is rotatably installed inside the installation box 301, the outer surface of the sealing frame 308 is in contact with the inner wall of the installation box 301, and the inner bottom of the installation box 301 A slide rail 309 is fixedly installed on the wall, through holes 310 in the same horizontal line are provided on the front and back sides of the sealing frame 308, a limit spring 311 is fixedly installed on the inner bottom wall of the sealing frame 308, an inner core 312 is fixedly installed on the top of the limit spring 311, a connecting handle 313 is fixedly installed on the top of the inner core 312, the top of the connecting handle 313 is slidably installed inside the slide rail 309, an air supply hole 314 is provided on the inner core 312, a support seat 315 is fixedly installed on the inner wall of the installation box 301, a servo motor 316 is fixedly installed on the inner bottom wall of the installation box 301, a connecting shaft 317 is fixedly installed on the lower end of the sealing frame 308, the connecting shaft 317 is rotatably installed inside the support seat 315, and the output shaft of the servo motor 316 is connected to the connecting shaft 317 by belt drive.

[0028] In this embodiment, the heat dissipation mechanism 3 is arranged at equal distances on the front and back of the disk body 1, the connecting pipe 303 enters the interior of the disk body 1 and is fixedly connected thereto, and the air supply tube 305 passes through the sealing plate 304 and is arranged at equal distances.

In this process, the air is first preliminarily filtered by the filter cover to remove dust particles in the air. When encountering rainy and snowy days or dusty roads, the output shaft of the servo motor 316 rotates to drive the sealing frame 308 to rotate.

At this time, the through hole 310 will be blocked by the inner core 312, so that the outside space cannot enter the wire-controlled chassis. While dissipating heat, the device protects the battery pack inside the wire-controlled chassis to prevent dust or rainwater from entering the battery pack. In addition, the water-cooled rack air-cooled method is used to improve the heat dissipation effect, and a filtering device is added to block some dust from entering, which can effectively increase the service life of the battery pack.
