[0038] Please refer to Figures 1 to 2, the embodiment of the present application provides a dual-head unmanned vehicle chassis, which is mainly used in logistics distribution unmanned vehicles, which mainly includes a chassis module 1, a frame module 2, an exterior module 3, a perception module 4, a power system module, an intelligent driving controller module 6 and a motor controller module 7, etc.; wherein, the frame module 2 is arranged above the chassis module 1, the exterior module 3 is arranged outside the frame module 2, the perception module 4 is embedded in the exterior module 3, the intelligent driving controller module 6 is arranged at the middle front end of the frame module 2, and the motor controller module 7 is arranged at the middle rear end of the frame module 2; the power system module includes battery modules 5 symmetrically arranged on the left and right sides of the middle of the frame module 2, a low-voltage module 8 integrated at the upper end of the battery module 5 on one side, and a high-voltage module 9 integrated at the upper end of the battery module 5 on the other side, the low-voltage module 8 is used to control and manage the auxiliary system of the vehicle, and the high-voltage module is used to drive the vehicle, both of which use existing products; the two battery modules 5 are connected in parallel through a high-voltage bus, which increases the total capacity of the battery and extends the power supply time.

[0039] As a preferred embodiment, the frame module 2 is a fully symmetrical frame structure, the exterior module 3 is a symmetrical split quick-release structure, and the perception module 4 is arranged symmetrically; the above modules are connected through standardized quick-release interfaces; the intelligent driving controller module 6 automatically switches the corresponding perception module 4 as the main sensor group according to the driving direction. It should be noted that this switching method adopts the existing technology and will not be described here. Through the coordinated cooperation and symmetrical arrangement of the above modules, the unmanned vehicle chassis has a completely symmetrical dual-head function, realizing true two-way travel; on the one hand, it significantly improves the maneuverability and operating efficiency of the vehicle in complex and narrow spaces; on the other hand, the vehicle does not need frequent starting and stopping and direction adjustment, thereby avoiding mechanical wear of the motor and braking system; in addition, rapid U-turns can also avoid traffic jams and reduce the impact on logistics efficiency.

[0040] In one embodiment, Figure 3 As shown, the chassis module 1 includes a first axle 101 and a second axle 102 symmetrically arranged at the front and rear ends of the middle part of the frame module 2; the first axle 101 or the second axle 102 is connected to a power transmission shaft 103, and the power transmission shaft 103 is connected to a drive motor assembly 104 via a universal joint, that is, the drive motor assembly 104 serves as a power source to transmit torque to the first axle 101 or the second axle 102 through the power transmission shaft 103 and the universal joint, thereby providing power to the entire vehicle; the first axle 101 and the second axle 102 both include axle bodies, half shafts, wheel hubs, braking systems, differentials and other components, and adopt existing solutions, which will not be elaborated here.

[0041] A first air storage system 105 is provided on one side of the drive motor assembly 104. The first air storage system 105 serves as the main air storage system and is composed of an electric air pump and an aluminum alloy air tank. It controls all pneumatic damping actions and is mainly used to provide a power source for the vehicle's pneumatic brake system and drive other pneumatic components (such as gearbox pneumatic shifting, door opening and closing mechanisms, etc.); a steering gear assembly 106 is provided in the middle of the first axle 101 and the second axle 102, and wheels 107 are equipped at both ends to realize the vehicle's four-wheel steering function, providing the basic conditions for the vehicle's two-way driving; multiple steering modes can be realized, such as two-wheel steering like traditional vehicles; or four-wheel steering, which can be divided into two situations: the front and rear wheels have opposite or same deflection directions. When the front and rear wheels have opposite deflection directions, the turning radius can be reduced; when the front and rear wheels have the same deflection directions, crab-shaped driving and rapid lane changes can be realized, thereby more flexibly coping with complex road conditions.

[0042] In one embodiment, the chassis module 1 further includes a first shock absorber assembly 108 and a second shock absorber assembly 109 fixed on the first axle 101 and the second axle 102, and the first shock absorber assembly 108 is connected to the first air storage system 105 and the second air storage system 110 arranged on one side of any wheel 107 through an air pipe. In this embodiment, the first shock absorber assembly 108 is an air pressure damper, and the second shock absorber assembly 109 is a leaf spring assembly. The air pressure damper and the leaf spring assembly cooperate to form a composite shock absorber structure to improve road adaptability. It should be noted that the first shock absorber assembly 108 and the second shock absorber assembly 109 adopt the existing solution, and the specific structure and principle are not described here. The second air storage system 110 is a secondary air storage system with redundant design. When the main air storage system fails (such as air leakage or compressor failure), the secondary air storage system can independently provide braking pressure to meet the functional safety standard requirements. At the same time, it can ensure that the steering assist or suspension adjustment is not interrupted and reduce the frequent start and stop of the compressor. The purpose of the isolation design of the second air storage system 110 and the first air storage system 105 is to reduce the probability of simultaneous failure of the two air storage systems and ensure the safety of the driving process.

[0046] In one embodiment, the two front and rear exterior trims 301 are mirror-symmetrical structures, and the two left and right exterior trims 302 are rotationally symmetrical structures. At this time, no matter whether the chassis moves forward or backward, the sensors, headlights, appearance, etc. are basically the same. At the same time, during production and processing, the front and rear molds can be shared, and the left and right molds can be shared, thereby greatly reducing the mold opening cost.

[0049] The present application also provides an unmanned vehicle, which is mainly used for unmanned logistics distribution, including a logistics cabinet and the dual-head unmanned vehicle chassis as described above. The logistics cabinet is fixedly connected to the dual-head unmanned vehicle chassis by bolts and the cargo box locking bracket 205, and the connection between the two is detachable, which is convenient for replacing the logistics cabinet as needed, such as large-grid cabinets, various-grid cabinets, retail cabinets, security cabinets, etc., thereby realizing different functions of the unmanned vehicle and applying it to other usage scenarios, with wide applicability.

[0050] As a preferred solution, the logistics cabinet also adopts a symmetrical structural design, so that the vehicle has a fully symmetrical structure in appearance. It can realize functions such as front-to-back steering, crab-shaped driving, etc. when the vehicle is driving, reducing the turning radius of the vehicle. On the one hand, it significantly improves the maneuverability and operating efficiency of the vehicle in complex and narrow spaces; on the other hand, the vehicle does not need frequent starting and stopping and direction adjustment, thereby avoiding mechanical wear of the motor and braking system; in addition, quick U-turns can also avoid traffic jams and reduce the impact on logistics efficiency.
