[0038] Please refer to Figures 1 to 2This application provides a dual-head unmanned vehicle chassis, mainly used in unmanned logistics delivery vehicles. It primarily includes a chassis module 1, a frame module 2, an exterior module 3, a sensing module 4, a power system module, an intelligent driving controller module 6, and a motor controller module 7. The frame module 2 is positioned above the chassis module 1, the exterior module 3 is located outside the frame module 2, the sensing module 4 is embedded in the exterior module 3, the intelligent driving controller module 6 is located at the front-middle section of the frame module 2, and the motor controller module 7 is located at the rear-middle section of the frame module 2. The power system module includes battery modules 5 symmetrically arranged on the left and right sides of the middle section of the frame module 2, a low-voltage module 8 integrated on the upper end of one side of the battery module 5, and a high-voltage module 9 integrated on the upper end of the other side of the battery module 5.

The two battery modules 5 are connected in parallel via a high-voltage bus, increasing the total battery capacity and extending the power supply time.

[0039] In a preferred embodiment, the chassis module 2 has a fully symmetrical frame structure, the exterior module 3 has a symmetrical split quick-release structure, and the sensing module 4 is arranged symmetrically. All modules are connected via standardized quick-release interfaces. The intelligent driving controller module 6 automatically switches the corresponding sensing module 4 as the main sensor group according to the driving direction. It should be noted that this switching method uses existing technology and will not be elaborated upon here. Through the coordinated operation and symmetrical arrangement of the modules, the unmanned vehicle chassis possesses a fully symmetrical dual-head function, achieving true bidirectional driving. On the one hand, this significantly improves the vehicle's maneuverability and operational efficiency in complex and narrow spaces; on the other hand, the vehicle does not require frequent starts, stops, and directional adjustments, thus avoiding mechanical wear on the motor and braking system. Furthermore, rapid U-turns can avoid traffic congestion and reduce the impact on logistics efficiency.

[0040] In one embodiment, such as 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 the power transmission shaft 103, and the power transmission shaft 103 is connected to the drive motor assembly 104 via a universal coupling. That is, the drive motor assembly 104, as a power source, transmits torque to the first axle 101 or the second axle 102 through the power transmission shaft 103 and the universal coupling, thereby providing power to the whole vehicle; the first axle 101 and the second axle 102 both include axle body, half shaft, wheel hub, braking system, differential and other components, which adopt existing solutions and will not be described in detail 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, consisting of an electric air pump and an aluminum alloy air tank. It controls all pneumatic damping operations and is mainly used to provide a power source for the vehicle's air pressure braking system and drive other pneumatic components (such as pneumatic gear shifting of the gearbox, door opening and closing mechanisms, etc.). Steering gear assemblies 106 are provided in the middle of the first axle 101 and the second axle 102, and wheels 107 are provided at both ends, realizing the four-wheel steering function of the vehicle and providing the basic conditions for bidirectional driving. It can realize multiple steering modes, such as two-wheel steering like traditional vehicles, or four-wheel steering, which can be divided into two situations: the front and rear wheels deflect in opposite or the same direction. When the front and rear wheels deflect in opposite directions, the turning radius can be reduced; when the front and rear wheels deflect in the same direction, crab-like driving can be realized for quick lane changes, thereby more flexibly dealing with complex road conditions.

[0042] In one embodiment, the chassis module 1 further includes a first shock absorber 108 and a second shock absorber 109 fixed to the first axle 101 and the second axle 102. The first shock absorber 108 is connected to a first air storage system 105 and a second air storage system 110 disposed on one side of any wheel 107 via an air pipe. In this embodiment, the first shock absorber 108 is a pneumatic damper, and the second shock absorber 109 is a leaf spring assembly. The pneumatic damper and the leaf spring assembly work together to form a composite shock absorber structure, improving road adaptability. It should be noted that the first shock absorber 108 and the second shock absorber 109 adopt existing solutions, and their specific structures and principles will not be elaborated here. The second air storage system 110 is a secondary air storage system and is a redundant design. When the main air storage system fails (such as due to air leakage or compressor failure), the secondary air storage system can independently provide braking pressure, meeting functional safety standards. At the same time, it can ensure that the steering assist or suspension adjustment is uninterrupted and reduce the frequent start-stop of the compressor. The purpose of the isolation design between 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.

[0043] In one embodiment, such as Figure 4 As shown, the chassis module 2 is basically symmetrical, that is, symmetrical from left to right and front to back. It mainly includes a main chassis 201 and a first sub-chassis 202 and a second sub-chassis 203 symmetrically arranged at both ends of the main chassis 201. The first sub-chassis 202 and the second sub-chassis 203 are each provided with a radar mounting bracket 204 at the end away from the main chassis 201 for symmetrical arrangement of lidar. Cargo box locking brackets 205 are symmetrically arranged on both sides of the first sub-chassis 202 and the second sub-chassis 203 for fixing the customizable logistics cabinet (not shown) mounted on the upper part of the dual-head unmanned vehicle chassis described in this application.

[0044] In one embodiment, the main frame 201 has a hollowed-out drive mounting area 206 in the middle for mounting the drive motor assembly 104, the first air storage system 105, a part of the power transmission shaft 103, and other modules. The first subframe 202 and the second subframe 203 have axle mounting areas 207 at their bottoms for mounting the first axle 101 and the second axle 102, respectively. The main frame 201 has battery mounting areas 208 on both sides for mounting the battery modules 5. The battery modules 5 adopt a split design, which not only increases the vehicle's range but also facilitates the arrangement of various components. A low-voltage electrical appliance mounting area 209 is located above one of the battery mounting areas 208, and a high-voltage electrical appliance mounting area 210 is located above the other battery mounting area 208. The low-voltage electrical appliance mounting area 209 is used to install low-voltage electrical appliances, and the high-voltage electrical appliance mounting area 210 is used to install high-voltage electrical appliances.

[0045] In one embodiment, such as Figure 5 As shown, the exterior module 3 includes two symmetrical front and rear exterior trim pieces 301 surrounding the front and rear sides of the frame module 2, and two symmetrical left and right exterior trim pieces 302 surrounding the left and right sides of the frame module 2. The front and rear exterior trim pieces 301 and the left and right exterior trim pieces 302 are all made of plastic or fiberglass and are fixed to the outside of the frame module 2 by bolts or clips, thus completely enclosing the outside of the frame module 2 inside. Each front and rear exterior trim piece 301 has a first electrically controlled door 303 symmetrically arranged on both sides for accommodating electronic locks, start buttons, and other electrical equipment, serving as the power control entry point for the unmanned vehicle. Each left and right exterior trim piece 302 has a second electrically controlled door 304 at one end for accommodating OBD, network ports, USB, and other electrical equipment, serving as the debugging entry point for the unmanned vehicle.

[0046] In one embodiment, the two front and rear exterior trim pieces 301 are mirror-symmetrical, and the two left and right exterior trim pieces 302 are rotationally symmetrical. In this case, regardless of whether the chassis moves forward or backward, the sensors, headlights, appearance, etc. are basically the same. At the same time, the front and rear molds and the left and right molds can be shared during production and processing, thereby greatly reducing the mold opening cost.

[0047] In one embodiment, such as Figure 6As shown, the front and rear exterior trim 301 includes a trim panel 3011, a crash beam 3012 disposed at the bottom of the trim panel 3011, and a fender 3013 disposed at the end of the trim panel 3011 and perpendicular to the trim panel 3011. The lighting module 10, display screen, etc. are symmetrically mounted on the trim panel 3011, and the emergency stop switch, etc. are symmetrically disposed on the fender 3013. One side of the fender 3013 is arc-shaped and surrounds the outer side of the wheel 107 with the left and right exterior trim 302. The trim panel 3011 and the crash beam 3012 are respectively provided with a plurality of sensor mounting holes 3014 for mounting various sensor components, including lidar, ultrasonic radar, camera, etc.

[0048] In one embodiment, such as Figure 7 As shown, the sensing module includes a first sensor assembly 401, a second sensor assembly 402, a third sensor assembly 403 disposed on the front and rear exterior trim pieces 301, and a fourth sensor assembly 404 and a fifth sensor assembly 405 disposed on the left and right exterior trim pieces 302; wherein, the first sensor assembly 401 is disposed in the middle of the trim panel 3011, the second sensor assembly 402 is disposed on one side of the first sensor assembly 401, the third sensor assembly 403 is disposed in the middle of the anti-collision beam 3012, the fourth sensor assembly 404 is disposed on the other end of the left and right exterior trim pieces 302 away from the second electric door 304, and the fifth sensor assembly 405 is disposed in the middle of the left and right exterior trim pieces 302. In this embodiment, the first sensor assembly 401 is a solid-state multi-line radar, with one set arranged at the front and one at the rear; the second sensor assembly 402 is a recognition camera, mainly used to identify obstacles and traffic lights, with one set arranged at the front and one at the rear; the third sensor assembly 403 is a multi-line lidar, with one set arranged at the front and one at the rear, mainly used to scan the surrounding environment; the fourth sensor assembly 404 is a single-line blind spot radar, mainly used to eliminate blind spots, with one set arranged diagonally; and the fifth sensor assembly 405 is a fisheye monitoring camera, used for real-time monitoring, with one set arranged at the front, rear, left, and right. The combination of the above-mentioned sensors can cover the entire surrounding environment of the chassis, ensuring driving safety. It should be noted that all of the above-mentioned sensors use existing products, which will not be described in detail here. Arranging each sensor assembly on the chassis facilitates the modularization of the superstructure (such as a logistics cabinet), allowing different modules to be installed to achieve different functions.

[0049] This application also provides an unmanned vehicle, mainly used in unmanned logistics delivery, including a logistics cabinet and a 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 facilitates the replacement of the logistics cabinet as needed, such as large compartment cabinets, individual compartment cabinets, retail cabinets, security cabinets, etc., thereby realizing different functions of the unmanned vehicle and applying it to other usage scenarios, making it widely applicable.

[0050] As a preferred option, the logistics cabinet also adopts a symmetrical structural design, achieving a fully symmetrical structure in the appearance of the entire vehicle. This enables functions such as unrestricted front and rear steering, dual front and rear steering, and crab-like driving, reducing the turning radius of the entire vehicle. On the one hand, this significantly improves the vehicle's maneuverability and operational efficiency in complex and narrow spaces; on the other hand, the vehicle does not require frequent starting, stopping, and directional adjustments, thus avoiding mechanical wear on the motor and braking system. In addition, quick U-turns can avoid traffic congestion and reduce the impact on logistics efficiency.

[0051] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
