Description

Technical Field

[0001] This invention relates to the field of logistics vehicle frames, and more particularly to a frame for an autonomous driving logistics vehicle. Background Technology

[0002] With the rapid development of e-commerce and smart logistics, autonomous logistics vehicles are increasingly being used in warehousing, transshipment, and last-mile delivery. Autonomous logistics vehicles typically adopt a modular design, consisting of a chassis frame, power system, battery pack, and replaceable functional body (such as cargo box, refrigerated box, recycling box, etc.) to meet different logistics operation needs. As the core structure that supports and connects various functional modules, the rationality of the frame design directly affects the assembly efficiency, maintenance convenience, and operational reliability of the entire vehicle.

[0003] Currently, the connection between the frame, battery, and body of autonomous logistics vehicles mainly uses traditional welding or bolt fastening. While welding provides high connection strength, it has significant drawbacks: First, the welding process is cumbersome, requires professional personnel, has a long production cycle, and cannot be disassembled after welding, making repair and replacement extremely inconvenient when the battery or body malfunctions. Second, the heat-affected zone of welding can easily lead to a decline in the performance of the frame materials, causing deformation or stress concentration, affecting the overall structural strength and service life of the frame. Third, traditional welding methods cannot achieve automatic power supply between the battery and the drive system, usually requiring additional plug-in interfaces, increasing structural complexity. The risk of poor contact exists in bolt fastening methods. Although bolt fastening offers some detachability, the large number of bolts and strict torque requirements result in low assembly efficiency. Furthermore, loosening is prone to occur under the long-term vibration conditions of logistics vehicles, affecting connection reliability. In addition, existing logistics vehicle frames mostly use single clips or bolts to fix the upper functional body, lacking an effective secondary clamping structure. Under complex road conditions, the vehicle body is prone to displacement or even detachment, posing a safety hazard. At the same time, existing designs fail to integrate the battery insertion action with functions such as power connection and vehicle body locking. The lack of coordination between functional modules leads to overall structural redundancy and numerous assembly steps.

[0004] Therefore, it is necessary to provide an autonomous driving logistics vehicle chassis to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention provides an autonomous driving logistics vehicle frame, which solves the problems of existing frames that mostly use welding or bolt connections. Welding makes the frame as a whole non-disassembly, while bolts are prone to loosening and have low efficiency. At the same time, the vehicle body fixation lacks secondary safety, and the battery insertion and power supply locking are not linked and integrated, resulting in structural redundancy and complicated assembly of existing frames.

A first sliding groove is provided on one side of the inner wall of the slot, the diameter of the first sliding groove is smaller than the diameter of the slot, and a slot is provided on the upper part of the bionic filling block. The second main frame is fixedly connected to two secondary frames on both sides, and the bottom of the second main frame is fixedly connected to the first main frame through four sets of connecting columns.

[0010] Preferably, the housing assembly includes a mounting plate, a housing is fixedly connected inside the mounting plate, a connecting groove is provided on the upper and lower sides of the inner wall of the housing, a guide groove is provided on one side of the inner wall of each of the two connecting grooves, the guide groove is arc-shaped and is provided on the inner wall of the housing, a limit groove is provided on the other side of the inner wall of the guide groove, and a plurality of heat sinks are fixedly connected to the outer side of the housing. The mounting plates are fixedly connected to the first main frame, the second main frame, and the underframe, respectively.

[0011] Preferably, the power supply component includes a battery, one end of which is fixedly connected to a plurality of docking blocks, and the other end of which has two mounting holes. A first elastic telescopic rod is fixedly connected to each of the two mounting holes. An anti-slip groove is provided on the side of the battery with the mounting holes, and a handle is fixedly connected to the other end of the two first elastic telescopic rods.

[0012] Preferably, guide blocks are fixedly connected to both the top and bottom of the battery; The position and shape of the guide block are adapted to the position and shape of the connecting groove, and the battery is slidably connected inside the housing.

[0013] Preferably, the docking assembly includes a first telescopic rod, a first spring is fixedly connected to the outside of the first telescopic rod, a metal plate is fixedly connected to one end of the first telescopic rod, a docking groove is fixedly connected to the other side of the metal plate, and the first telescopic rod is sleeved in the bearing; The bearing is snapped onto one side of the inner wall of the housing, and the metal sheet is snapped onto the docking block behind the battery through a docking groove, with the rear of the battery in contact with the metal sheet.

[0016] Compared with related technologies, the autonomous driving logistics vehicle frame provided by this invention has the following advantages: This invention provides an autonomous driving logistics vehicle frame. When the battery is inserted into the housing, the rear of the battery contacts a metal plate, triggering the compression of a first telescopic rod and a first spring. At this time, the docking block at the rear of the battery engages with the docking groove on the surface of the metal plate. When the battery is fully inserted into the housing, the guide block on the surface of the battery enters the guide groove along the connecting groove. At this point, the battery needs to be rotated 90 degrees clockwise to allow the guide block to slide into the limiting groove along the guide groove. Simultaneously, the metal plate rotates, and the first telescopic rod drives the gear to rotate. The gear synchronously drives the toothed plates on both sides and the limiting plate to move towards each other, thereby aligning the upper part of the second main frame and the secondary frame. The device clamps and locks the vehicle body, achieving a rigid connection between the vehicle body and the frame. This allows the device to initially position and fix the upper part of the vehicle body using slots and grooves located on the upper part of the second main frame, while the gear-clamping structure provides secondary clamping and fixation to the bottom of the vehicle body, forming a dual fixing system of "upper clamp and lower clamp". The slots and grooves bear the vertical load and initial limiting function of the vehicle body, while the gear-clamping structure provides lateral constraint and secondary locking force. The two complement each other and effectively avoid the safety hazards of vehicle body displacement or even detachment caused by vibration and bumps under complex road conditions due to a single fixing method, significantly improving the overall reliability and safety of the vehicle body installation.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figures 1 to 8 The autonomous driving logistics vehicle frame includes: a frame mechanism 1 and a module mechanism 2, with the frame mechanism 1 connected to the module mechanism 2; The frame mechanism 1 includes a frame assembly 11, four sets of connecting columns 13 disposed below the frame assembly 11, and a primary main frame (14), wherein the primary main frame 14 is located below the connecting columns 13. The module mechanism 2 includes a housing assembly 21, a power supply assembly 22 located within the housing assembly 21, a docking assembly 23 connected to the power supply assembly 22, a drive assembly 24 connected to the power supply assembly 22, and an isolation assembly 25, wherein the isolation assembly 25 is located outside the drive assembly 24. This device relies on a plug disposed above the secondary main frame 111. The slots 113 and 115 provide initial positioning and fixation for the upper part of the vehicle body, while the gear 241 clamping structure provides secondary clamping and fixation for the bottom of the vehicle body, forming a dual fixing system of "upper clamping and lower clamping". The slots 113 and 115 bear the vertical load and initial positioning function of the vehicle body, while the gear 241 clamping structure provides lateral constraint and secondary locking force. The two complement each other and effectively avoid the safety hazards of vehicle body displacement or even falling off due to vibration and bumps in complex road conditions caused by a single fixing method, significantly improving the overall reliability and safety of vehicle body installation.

[0021] The frame assembly 11 is fixedly connected to four sets of connecting columns 13 at its lower part. Each of the four sets of connecting columns 13 is composed of multiple hollow steel columns. Secondary frames 12 are fixedly connected to both sides of the frame assembly 11. Steel leaf springs 16 are provided below each of the two secondary frames 12. The bottom ends of the connecting columns 13 are fixedly connected to the primary frame 14 and the base frame 15, respectively. The base frame 15 is fixedly connected to the primary frame 14. The inner wall of the outer shell assembly 21 is snapped into the power supply assembly 22. The rear of the power supply assembly 22 is snapped into the docking assembly 23. The docking assembly 23 is rotatably connected inside the outer shell assembly 21. The rear of the docking assembly 23 is drive-connected to the drive assembly 24. The drive assembly 24 is slidably connected inside the isolation assembly 25. The isolation assembly 25 is fixedly connected to the outer shell assembly 21. After the battery 221 is completely inserted into the shell 212, the rear of the battery 221 is connected to the docking assembly 23. The connecting block 222 and the mating groove 234 on the surface of the metal sheet 233 complete the initial docking. At the same time, the guide block 227 on the surface of the battery 221 is inserted into the connecting groove 213 and the guide groove 214 in the housing 212, which plays a role in initial positioning and guidance. Then, the battery 221 is rotated, and the connecting block 222 drives the metal sheet 233 to rotate. The guide block 227 gradually slides into the limiting groove 215 along the guide groove 214. The first telescopic rod 231 and the first spring 232 connected to the metal sheet 233 continuously squeeze the battery 221 under the action of elastic force, firmly locking the battery 221 into the limiting groove 215, completing the final fixation of the battery 221. This structure combines rotation locking with elastic pre-tightening, which not only ensures the convenience of battery 221 installation (only rotation operation is required), but also ensures that the battery 221 will not loosen or fall off under the vibration conditions of vehicle driving through the continuous elastic pressure of the first spring 232, resulting in high fixation reliability.

[0022] The frame assembly 11 includes a secondary main frame 111. The inner wall of the secondary main frame 111 is provided with a biomimetic filling block 112. Multiple slots 113 are formed above the secondary main frame 111. A first sliding groove 114 is formed on one side of the inner wall of each slot 113. The diameter of the first sliding groove 114 is smaller than the diameter of the slot 113. A slot 115 is formed above the biomimetic filling block 112. Two secondary frames are respectively connected to the two sides of the secondary main frame 111. 12. Fixed connection: The second main frame 111 is fixedly connected to the first main frame 14 via four sets of connecting posts 13. The outer shell assembly 21 includes a mounting plate 211, and a shell 212 is fixedly connected inside the mounting plate 211. Connecting grooves 213 are provided on the upper and lower sides of the inner wall of the shell 212. Guide grooves 214 are provided on one side of the inner wall of each of the two connecting grooves 213. The guide grooves 214 are arc-shaped and are formed on the shell 212. On the inner wall of 12, a limiting groove 215 is opened on the other side of the inner wall of the guide groove 214. Multiple heat sinks 216 are fixedly connected to the outer side of the housing 212. The mounting plate 211 is fixedly connected to the first main frame 14, the second main frame 111 and the base frame 15 respectively. Since the rear of the battery 221 is connected to the elastic structure by a metal sheet 233, when the battery 221 is inserted into the housing 212, the front end of the battery 221 first makes a squeezing contact with the metal sheet 233. After the metal sheet 233 is subjected to force, it moves a distance, so that the conductive contact between the metal sheet 233 and the vehicle drive structure is automatically connected, realizing the instant power supply connection between the battery 221 and the drive system. This makes the device not need to set up an additional independent plug-in power supply interface, simplifying the power supply circuit structure, reducing the risk of contact resistance and poor contact. At the same time, the battery 221 insertion action itself is used as the power supply trigger condition, realizing the automated linkage effect of "plug and power on", which greatly improves the assembly efficiency and power supply reliability. By filling the interior of the secondary main frame 111 with biomimetic filler blocks 112, the device significantly reduces the amount of solid material used in the frame through the hollow design of the secondary frame 111, fundamentally reducing the weight of the frame itself. Combined with the hollow gradient biomimetic filler blocks 112, which are similar to bird skeletons, with density and wall thickness decreasing gradually from the outside to the inside along the direction of stress, the material redundancy in non-critical areas is further reduced while ensuring the structural strength of key load-bearing areas. This results in a significant overall weight reduction of the frame, directly reducing the curb weight of the autonomous driving logistics vehicle, thereby reducing battery energy consumption, extending the range per charge, and freeing up more effective payload for carrying goods or functional vehicle bodies, thus improving the actual carrying efficiency of the logistics vehicle.

[0023] The power supply assembly 22 includes a battery 221. One end of the battery 221 is fixedly connected to multiple docking blocks 222. The other end of the battery 221 has two mounting holes 223, each containing a first elastic telescopic rod 225. An anti-slip groove 224 is provided on the side of the battery 221 with the mounting holes 223. A handle 226 is fixedly connected to the other end of each of the first elastic telescopic rods 225. Guide blocks 227 are fixedly connected above and below the battery 221, their positions and shapes matching the positions and shapes of the connecting grooves 213. The battery 221 is slidably connected within the housing 212. The docking assembly 23 includes a first telescopic rod 231, with a first spring 232 fixedly connected to its exterior. One end of the device is fixedly connected to a metal sheet 233, and the other side of the metal sheet 233 is fixedly connected to a docking groove 234. The first telescopic rod 231 is sleeved in the bearing 235, and the bearing 235 is snapped into one side of the inner wall of the housing 212. The metal sheet 233 is snapped into the docking block 222 behind the battery 221 through the docking groove 234. The rear of the battery 221 is in contact with the metal sheet 233. Because a first elastic telescopic rod 225 and a handle 226 are provided, and the first elastic telescopic rod 225 is set in the mounting hole 223, the handle 226 can be used to exert force when rotating the battery 221, which reduces the difficulty of using the device. After use, the first elastic telescopic rod 225 can drive the handle 226 to fit against the surface of the battery 221, avoiding the handle 226 from protruding and affecting the streamlined appearance of the vehicle and the transportation stacking space. By designing the distribution groove 252, gear 241, and toothed plate 242, the vehicle body is clamped by the limiting plate 246 after the gear 241 moves the toothed plate 242. This not only achieves rigid positioning of the vehicle body and the frame, but also strengthens the clamping force of the limiting plate 246 on the vehicle body and significantly improves the fatigue resistance and structural stability of the limiting plate 246 under long-term vibration conditions.

[0024] The drive assembly 24 includes a gear 241, with toothed plates 242 meshing above and below the gear 241. The two toothed plates 242 are respectively fixedly connected to two second-order elastic telescopic rods 243. A third-order elastic telescopic rod 244 is fixedly connected above one toothed plate 242, and a reinforcing rod 245 is fixedly connected above the other toothed plate 242. Limiting plates 246 are fixedly connected to the top ends of both the reinforcing rod 245 and the third-order elastic telescopic rod 244. The gear 241 is drively connected to the first-order telescopic rod 231. The isolation assembly 25 includes an isolation plate 251, with two distribution grooves 252 formed within the isolation plate 251. The limiting plates 246 are slidably connected within the distribution grooves 252. The two second-order elastic telescopic rods... All 243 are fixedly connected to the isolation plate 251, which is fixedly connected to the top of the base frame 15. The isolation plate 251 is fixedly connected to the housing 212. During the locking process of the battery 221, the first telescopic rod 231 connected to the metal plate 233 drives the two side tooth plates 242 and the limiting plate 246 to move towards each other through the rotation of the gear 241, thereby synchronously limiting and fixing the different vehicle bodies above the second main frame 111 and the secondary frame 12. This allows the device to mechanically link the fixing action of the battery 221 with the clamping action of the vehicle body. While the battery 221 is locked, the horizontal clamping of the vehicle body above is automatically completed. No additional drive source or manual operation is required, achieving the synergistic effect of "one action, multiple functions". The structure is compact and the action is continuous. The entire fixed structure of the device adopts a detachable mechanical connection method, completely abandoning the traditional welding process and avoiding problems such as heat-affected zone deformation, material performance degradation, and non-removability caused by welding. At the same time, since the vehicle body is fixed by the slot 113, the slot 115 and the gear 241, different functional vehicle bodies (such as cargo boxes, refrigerated boxes, recycling boxes, etc.) can be quickly replaced according to actual logistics operation needs. This realizes modular quick replacement of the vehicle body, which greatly reduces maintenance costs and production cycle, and improves the scenario adaptability and usage flexibility of autonomous driving logistics vehicles.

[0025] The working principle of the autonomous driving logistics vehicle frame provided by this invention is as follows: In use, place the vehicle body above the secondary frame 12 and the second main frame 111, insert the vehicle body locking block into the slot 113 and the locking groove 115 above the secondary frame 12 and the second main frame 111, and then move the vehicle body slightly so that the locking block of the vehicle body is locked into the first sliding groove 114, thus completing the initial fixation of the vehicle body and the frame mechanism 1. After initial fixation, the battery 221 is inserted into the housing 212. The rear of the battery 221 is pressed against the metal plate 233, triggering the compression of the first telescopic rod 231 and the first spring 232. At this time, the docking block 222 at the rear of the battery 221 engages with the docking groove 234 on the surface of the metal plate 233. When the battery 221 is fully inserted into the housing 212, the guide block 227 on the surface of the battery 221 enters the guide groove 214 along the connecting groove 213. At this time, the battery 221 needs to be rotated 90 degrees clockwise so that the guide block 227 slides into the limiting groove 215 along the guide groove 214. At the same time, the metal plate 233 is rotated and the gear 241 is rotated through the first telescopic rod 231. The gear 241 synchronously drives the toothed plates 242 on both sides and the limiting plate 246 to move towards each other, thereby clamping and locking the vehicle body above the second main frame 111 and the secondary frame 12, realizing a rigid connection between the vehicle body and the frame. At the same time, the rotation of the metal piece 233 also triggers the closure of the power supply circuit, and the entire vehicle system immediately powers on and performs a self-test. When it is necessary to replace the vehicle body with a different function, the battery 221 is slightly squeezed to make the guide block 227 disengage from the limiting groove 215 and enter the guide groove 214. Then, the handle 226 is rotated counterclockwise, thereby driving the battery 221 to rotate counterclockwise, causing the guide block 227 to reset along the guide groove 214. The battery 221 is then pulled back to disengage from the docking groove 234, and the metal piece 233 is reset with the return of the first spring 232. The power supply circuit is disconnected, and the two limiting plates 246 will also loosen their clamping on the vehicle body, completing the quick disassembly and replacement of the vehicle body.

[0026] Compared with related technologies, the autonomous driving logistics vehicle frame provided by this invention has the following advantages: Because a first elastic telescopic rod 225 and a handle 226 are provided, and the first elastic telescopic rod 225 is located in the mounting hole 223, the handle 226 can be used to exert force when rotating the battery 221, which reduces the difficulty of using the device. After use, the first elastic telescopic rod 225 can drive the handle 226 to fit against the surface of the battery 221, preventing the handle 226 from protruding and affecting the streamlined appearance of the vehicle and the transport stacking space. By designing the distribution groove 252, gear 241 and toothed plate 242, after the toothed plate 242 is moved by the gear 241 and the vehicle body is clamped by the limiting plate 246, not only is the rigid limiting of the vehicle body and the frame achieved, but the distribution groove 252 also strengthens the clamping force of the limiting plate 246 on the vehicle body and significantly improves the fatigue resistance and structural stability of the limiting plate 246 under long-term vibration conditions. During the locking process of the battery 221, the first telescopic rod 231 connected to the metal plate 233 rotates through the gear 241 to drive the toothed plates 242 on both sides and the limiting plate 246 to move towards each other, thereby synchronously limiting and fixing the different vehicle bodies above the second main frame 111 and the secondary frame 12. This allows the device to mechanically link the fixing action of the battery 221 with the clamping action of the vehicle body. While the battery 221 is locked, the lateral clamping of the vehicle body above is automatically completed. No additional drive source or manual operation is required, achieving a synergistic effect of "one action, multiple functions". The structure is compact and the action is smooth.
