Description

Technical Field

[0001] This utility model relates to the field of warehouse material handling robots, and in particular to a stealthy AGV vehicle body shell structure. Background Technology

[0002] With the rapid development of intelligent warehousing technology, warehouse transport robots with automatic navigation functions have been widely used in the warehousing and logistics field. As a commonly used model in the warehousing and logistics robot field, the AGV (Automated Guided Vehicle) has become an important transportation tool. Currently, the shell of the AGV mainly serves to protect the vehicle and provide installation support for some electrical structural components. However, existing AGV shells have some problems that affect their versatility and effectiveness, as follows:

[0003] (i) Existing AGV shell structures are mostly one-piece or split multi-screw structures, using a large number of screws, which increases the installation steps and difficulty. At the same time, the screw layout on the shell surface reduces the integrity and affects the aesthetics. In addition, functional components such as lasers and RGBD cameras are directly fixed to the shell, and different sizes of robots need to match the corresponding laser mounting structure, which increases production costs and limits versatility.

[0004] (ii) Furthermore, the existing shell structure layout lacks flexibility and scalability, making it difficult to adapt to changes in the configuration of different functional modules or the needs of later upgrades. The internal space is fixed, and the installation positions of key sensors such as LiDAR and cameras are fixed with limited room for adjustment. When replacing different models or specifications of sensors, it is often necessary to redesign or customize the local structure of the shell, which cannot quickly respond to functional iteration or customization needs, thus limiting the adaptability and upgrade potential of the robot. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a concealed AGV vehicle body shell structure to solve one or more problems in the prior art.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A concealed AGV (Automated Guided Vehicle) body shell structure includes a front structure at the front end of the AGV body and a rear structure at the rear end of the AGV body. The front structure includes a front cover and a front chassis, and the rear structure includes a rear cover and a rear chassis. The shell structure also includes a fixing component, through which the front cover and the rear cover are respectively connected to the front chassis and the rear chassis. The front chassis includes a first connecting portion, and the rear chassis includes a second connecting portion. The first connecting portion cooperates with the second connecting portion to connect the front chassis and the rear chassis. When the front chassis and the rear chassis are connected, a gap is formed between the front cover and the rear cover.

[0008] Furthermore, the outer casing structure also includes a bracket assembly, including a first bracket and a second bracket disposed on both sides of the front chassis, and a third bracket and a fourth bracket disposed on both sides of the rear chassis; the first bracket, the second bracket, the third bracket and the fourth bracket are all provided with mounting holes on their surfaces; the fixing assembly includes a snap-fit ​​mechanism, which is disposed in the mounting holes.

[0009] Furthermore, the snap fastener includes a snap-fit ​​part and a positioning part that are connected to each other. The end face area of ​​the snap-fit ​​part is uniformly larger than the end face area of ​​the mounting hole. The mounting hole surface is provided with a guide groove, and the surface of the positioning part is provided with a protrusion that cooperates with the guide groove. The positioning part also includes a first movable part. When the positioning part is engaged with the mounting hole, the first movable part moves and is engaged with one end face of the mounting hole.

[0010] Furthermore, mounting brackets are provided on both sides of the front cover and both sides of the rear cover. The mounting brackets are provided with recessed portions, and slots are also provided on the surface of the recessed portions. The fixing component includes a snap-fit ​​block, which includes an insert portion and a mating portion connected to each other. The insert portion is gap-fitted into the recessed portion, and the mating portion is fitted into the slot and partially protrudes from the mounting bracket.

[0011] Furthermore, the fixing component also includes a buckle, the buckle having a second movable part, and the mating part having a positioning hole on its surface. When the buckle is engaged with the buckle block, the second movable part moves and engages with the positioning hole.

[0012] Furthermore, some of the buckles are connected to the surfaces of the front cover and the rear cover respectively, and limiting holes are also provided on the front chassis and the rear chassis. When the front cover is installed on the front chassis and / or the rear cover is installed on the rear chassis, some of the buckles also cooperate with the limiting holes.

[0013] Furthermore, the front structure also includes a headlight assembly connected to the front cover and symmetrically arranged about the front cover, the headlight assembly including a first light element and a first light cover connected to each other, wherein the first light element is disposed close to the front cover; the housing structure also includes a display screen, an RGBD camera and a navigation lidar disposed on the front chassis and extending through the front cover.

[0014] Furthermore, the front structure also includes a first anti-collision strip, which is connected to the front chassis and also fits into the front cover.

[0015] Furthermore, the rear structure also includes a rear light assembly connected to the rear cover, the rear light assembly including a second light piece and a second light cover connected to each other, wherein the second light piece is disposed close to the rear cover; the housing structure also includes an obstacle avoidance lidar, a power switch, an emergency stop switch, a debugging interface and a charging interface disposed on the rear chassis and extending through the rear cover.

[0016] Furthermore, the rear structure also includes a second anti-collision strip, which is connected to the rear chassis and also fits into the rear cover.

[0017] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0018] (I) This novel design ingeniously utilizes a synergistic structure involving snap-fit ​​detachers, snap-fit ​​blocks, and the snaps themselves, replacing the traditional method that requires numerous screws for fixing. The snap-fit ​​detacher uses its snap-fit ​​portion to precisely engage with the pre-drilled mounting holes on the bracket assembly, achieving an initial stable connection. Next, the snap-fit ​​block, through its insert portion, matches and engages with the recessed portion on the mounting bracket. Then, the snap-fit, through its second movable portion, engages and locks with the positioning hole, further enhancing the overall structural stability. Finally, the snap-fit ​​engages again with the snap-fit ​​detacher, completing the final fixing process of the entire device. This innovative design significantly reduces the number of screws used, effectively simplifying the installation process and making assembly more convenient and efficient. It also completely eliminates screw holes on the product surface caused by screw fixing, thereby greatly improving the product's aesthetic appearance.

[0019] (II) This new type of robot features a modular design with an overall structure. By connecting the front cover to the front chassis and the rear cover to the rear chassis, and then connecting the front chassis to the rear chassis, a gap is formed between the front cover and the rear cover, which can meet the passage requirements of the front chassis and the rear chassis to generate rotation angles due to floating. The separate design of the front cover and the rear cover not only facilitates the quick replacement of internal components, but also allows for local upgrades or adjustments without interfering with other modules. In addition, the installation positions of key sensors and functional modules such as navigation laser radar, obstacle avoidance laser radar, debugging interface, and charging interface on the front cover and the rear cover can be flexibly adjusted or replaced. Users can flexibly add or remove functional modules according to actual needs to adapt to different application scenarios and task requirements, which significantly enhances the robot's adaptability and upgrade potential.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description of a concealed AGV vehicle body shell structure proposed by this utility model, in conjunction with the accompanying drawings and specific embodiments, will provide further details. The advantages and features of this utility model will become clearer according to the following description. It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions, used only to facilitate and clearly illustrate the purpose of the embodiments of this utility model. Please refer to the accompanying drawings to make the objectives, features, and advantages of this utility model more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only used to complement the content disclosed in the specification, for those skilled in the art to understand and read, and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by this utility model, should still fall within the scope of the technical content disclosed in this utility model.

[0028] Please see Figures 1 to 6 The AGV body shell structure of this embodiment includes a front structure 1 located at the front end of the AGV body and a rear structure 2 located at the rear end of the AGV body. Both the front structure 1 and the rear structure 2 are manufactured using an integral molding process. The front structure 1 includes a front cover 101 and a front chassis 102, and the rear structure 2 includes a rear cover 201 and a rear chassis 202. The shell structure also includes a fixing component 3. The fixing component 3 is designed to enhance the overall stability of the shell structure, effectively resisting external impacts and vibrations, ensuring a tight fit even in complex working environments, while also considering ease of operation. The front cover 101 and the rear cover 201 are respectively connected to the front chassis 102 and the rear chassis 202 via fixing components 3. The front chassis 102 includes a first connecting part 1021, and the rear chassis 202 includes a second connecting part 2021. The first connecting part 1021 cooperates with the second connecting part 2021 to connect the front chassis 102 and the rear chassis 202. That is, in this embodiment, the front cover 101 and the rear cover 201 are not directly connected, but form a whole through the connection of the front chassis 102 and the rear chassis 202. When the front chassis 102 and the rear chassis 202 are connected, a gap is formed between the front cover 101 and the rear cover 201. Since the structure of the front chassis 102 and the rear chassis 202 has floating properties, a certain rotation angle will be generated to meet the requirements of sufficient passage. Therefore, a gap is set between the front cover 101 and the rear cover 201 to meet the requirements of the rotation angle.

[0029] Furthermore, the outer shell structure also includes a bracket assembly 4, preferably made of a high-strength alloy, which provides sufficient support while ensuring lightweight construction, preventing deformation or damage due to long-term use or external forces, and facilitating subsequent maintenance and replacement. Specifically, it includes a first bracket 401 and a second bracket 402 disposed on both sides of the front chassis 102, and a third bracket 403 and a fourth bracket 404 disposed on both sides of the rear chassis 202. The first bracket 401 and the second bracket 402 partially connect the front cover 101 and the front chassis 102, and the third bracket 403 and the fourth bracket 404 partially connect the rear cover 201 and the rear chassis 202. Mounting holes 5 are provided on the surfaces of the first bracket 401, the second bracket 402, the third bracket 403, and the fourth bracket 404. The fixing assembly 3 includes a snap-fit ​​301 disposed within the mounting hole 5. Specifically, the snap fastener 301 includes a snap-fit ​​part 3011 and a positioning part 3012 connected to each other. The end face area of ​​the snap-fit ​​part 3011 is uniformly larger than the end face area of ​​the mounting hole 5. That is, when the snap fastener 301 is set in the mounting hole 5, part of the snap-fit ​​part 3011 is snapped into the hole surface of the mounting hole 5, thereby preventing the snap fastener 301 from falling off.

[0030] Furthermore, the mounting hole 5 is also provided with a guide groove 501. In this embodiment, two guide grooves 501 are symmetrically arranged with respect to the mounting hole 5. The positioning part 3012 is provided with a protrusion 30121 that cooperates with the guide groove 501. Thus, the cooperation between the protrusion 30121 and the guide groove 501 ensures the guiding accuracy during installation and also improves the stability of installing the snap-on detachment 301. The positioning part 3012 also includes a first movable part 30122. In this embodiment, two first movable parts 30122 are symmetrically arranged. When the positioning part 3012 is engaged with the mounting hole 5, the first movable part 30122 moves and is locked on one end face of the mounting hole 5. That is, the first movable part 30122 is pressable. When the first movable part 30122 is under force, the distance between the two first movable parts 30122 decreases, and conversely, when it is not under force, the distance increases to achieve the locking effect.

[0031] Furthermore, mounting brackets 6 are provided on both sides of the front cover 101 and both sides of the rear cover 201. The mounting brackets 6 are provided with recessed portions 601, and slots 602 are also provided on the surface of the recessed portions 601. The fixing component 3 also includes a snap-fit ​​block 302. The snap-fit ​​block 302 includes an insert portion 3021 and a mating portion 3022 that are connected to each other. The insert portion 3021 is fitted with the recessed portion 601 with a clearance, and the mating portion 3022 is fitted with the slot 602 and partially protrudes from the mounting bracket 6. That is, the recessed portion 601 of the mounting bracket 6 plays a role in supporting and fixing the snap-fit ​​block 302, so as to facilitate the connection of the front cover 101 and the front chassis 102, and the rear cover 201 and the rear chassis 202 by the fixing component 3. Optionally, the buckle block 302 can be fixed to the mounting bracket 6 using screws or other parts to further ensure the connection and fixation of the buckle block 302 with the front cover 101 or the rear cover 201.

[0032] Furthermore, the fixing component 3 also includes a buckle 303, which includes a second movable part 3031. The mating part 3022 has a positioning hole 30221 on its surface. When the buckle 303 engages with the buckle block 302, the second movable part 3031 moves and engages with the positioning hole 30221. Similarly, the second movable part 3031 changes shape under external force, similar to the effect of the first movable part 30122. When the second movable part 3031 is engaged in the positioning hole 30221, the buckle 303 and the buckle block 302 are connected and fixed. The engaging part 3011 of the buckle detachment 301 is also used to engage with the buckle 303, such as... Figures 4-6 The assembly of the fixing component 3 shown, through the coordinated action of the snap fastener 301, the snap fastener block 302 and the snap fastener 303, makes the connection between the front cover 101 and the front chassis 102 and the rear cover 201 and the rear chassis 202 more stable and reliable.

[0033] In actual operation, the insert portion 3021 of the buckle block 302 is first aligned with the recessed portion 601 for initial positioning, and then further fixed by the cooperation of the mating portion 3022 and the slot 602. Next, the second movable portion 3031 of the buckle 303 is aligned with the positioning hole 30221, and deformed under external force to smoothly engage, thereby achieving a firm connection between the buckle 303 and the buckle block 302. Finally, after installing the buckle detachment 301 into the mounting hole 5, the installed buckle 303 is inserted into the buckle detachment 301 to complete the use of the fixing component 3. This design not only simplifies the assembly process but also improves the connection accuracy between components, providing a strong guarantee for the overall performance of the AGV body shell.

[0034] Specifically, some buckles 303 are connected to the surfaces of the front cover 101 and the rear cover 201, and limiting holes 7 are provided on the front chassis 102 and the rear chassis 202. When the front cover 101 is installed on the front chassis 102 and / or the rear cover 201 is installed on the rear chassis 202, some of the buckles 303 also cooperate with the limiting holes 7. Through this design, the front cover 101 and the rear cover 201 can be more securely connected to the front chassis 102 and the rear chassis 202, respectively, effectively avoiding loosening problems caused by vibration or external force. In practical applications, this structure can also be flexibly adjusted as needed to adapt to the requirements of different models or specifications of AGV vehicle body shells, thus demonstrating its high versatility and practicality.

[0035] Furthermore, the front structure 1 also includes a front light assembly 103 connected to the front cover 101 and symmetrically arranged about the front cover 101. The front light assembly 103 includes a first light element 1031 and a first light cover 1032 connected to each other. The first light element 1031 is positioned close to the front cover 101. Preferably, the first light element 1031 and the first light cover 1032 are interlocked using known technology, and then the interlocked first light element 1031 and the first light cover 1032 are installed onto the front cover 101 with screws or other parts. The outer shell structure also includes a display screen 8, an RGBD camera 9, and a navigation lidar 10 disposed on the front chassis 102 and extending through the front cover 101. The display screen 8 is used to display the real-time operating status and navigation information of the AGV vehicle body. Its position design conforms to ergonomic principles, making it convenient for operators to view clearly from different angles. The RGBD camera 9 captures depth information and color images of the environment, providing the AGV with precise visual perception capabilities, thus supporting path planning and obstacle recognition in complex scenarios. The navigation LiDAR 10 generates point cloud data through high-precision scanning of the surrounding environment, further enhancing the vehicle's positioning accuracy and dynamic obstacle avoidance performance. The integration of these components not only improves the functionality of the AGV but also ensures its stability and reliability in various application scenarios.

[0036] Correspondingly, the rear structure 2 also includes a rear light assembly 203 connected to the rear cover 201. The rear light assembly 203 includes a second light element 2031 and a second light cover 2032 connected to each other. The second light element 2031 is disposed close to the rear cover 201. Preferably, the second light element 2031 and the second light cover 2032 are interlocked using known technology, and then the interlocked second light element 2031 and the second light cover 2032 are installed to the rear cover 201 with screws and other parts. The outer shell structure also includes an obstacle avoidance laser radar 11, a power switch 12, an emergency stop switch 13, a debugging interface 14, and a charging interface 15 disposed on the rear chassis 202 and extending to the rear cover 201. The obstacle avoidance laser radar 11 is used to monitor obstacles behind in real time to ensure the safety of the vehicle when reversing or turning. The power switch 12 is designed for one-button operation, allowing users to quickly start or stop the vehicle's power. The emergency stop switch 13 is located in a conspicuous and easily accessible position to quickly cut off power output in emergencies, ensuring the safety of equipment and personnel. The debugging interface 14 adopts a standardized design, supporting the connection of various external devices, facilitating system maintenance and parameter adjustments by technicians. The charging interface 15 is compatible with mainstream charging protocols, enabling efficient and stable power replenishment to meet the needs of long-term operation. The layout of these functional modules is carefully planned, ensuring both ease of operation and a compact and aesthetically pleasing overall structure.

[0037] Furthermore, the front structure 1 also includes a first anti-collision strip 104, which is connected to the front chassis 102 and also fits into the front cover 101. The rear structure 2 also includes a second anti-collision strip 204, which is connected to the rear chassis 202 and also fits into the rear cover 201. Preferably, both the first anti-collision strip 104 and the second anti-collision strip 204 are made of highly elastic material, which can effectively absorb impact force in the event of a collision and reduce damage to the vehicle body. At the same time, the design of the first anti-collision strip 104 and the second anti-collision strip 204 also takes into account the consistency with the overall vehicle appearance, and perfectly fits the front cover 101 and the rear cover 201 through smooth lines, which not only improves the overall aesthetics but also enhances the protective performance.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
