Description

Technical Field

[0001] The utility model relates to the technical field of AGV, in particular to a frame plate with good obstacle avoidance effect. Background Art

[0002] In the design of traditional AGV (Automated Guided Vehicle), for different application scenarios, there are usually two main frame plate configuration modes: the low-profile frame plate and the QR code frame plate. The former tends to adopt a large-volume navigation laser module (such as Figure 1 shown by the reference numeral 10 in the figure), which is installed at the central position of the rear part of the frame plate to achieve precise path tracking and navigation. However, this design has led to a significant increase in the overall size of the frame, which not only affects the space utilization efficiency but may also limit the operational flexibility of the vehicle in narrow environments.

[0003] On the other hand, the obstacle avoidance laser module of the QR code frame plate is usually fixed at the left rear corner, aiming to ensure that the vehicle can effectively detect obstacles in a dynamic environment and ensure operation safety. However, this layout often generates an obvious obstacle avoidance blind area behind the frame plate (such as Figure 2 the shaded area shown in the figure). Especially when the vehicle rotates, as the body rotates, the swept area of the obstacle avoidance blind area expands accordingly, significantly increasing the potential collision risk and reducing the operation safety.

[0004] More importantly, in the traditional design, the low-profile frame plate and the QR code frame plate are independent of each other and cannot share hardware resources, which means that each mode requires a complete frame structure, not only increasing the manufacturing cost but also causing redundancy and waste of materials and design resources.

[0005] Therefore, it is necessary to provide a frame plate with good obstacle avoidance effect to solve the above technical problems. Summary of the Utility Model

[0006] To solve the above technical problems, the utility model provides a frame plate with good obstacle avoidance effect, which can optimize the frame plate design, reduce space occupation, eliminate the obstacle avoidance blind area, and promote resource sharing between different mode frame plates without sacrificing performance, so as to improve the overall efficiency and economy of the AGV system.

[0007] A frame plate with good obstacle avoidance effect provided by the utility model includes a rear frame located at the rear side of the frame plate. A rear through groove is horizontally and inwardly arranged on the rear end face of the rear frame, and the rear through groove penetrates through the rear frame from left to right. In the rear through groove, a navigation laser module or an obstacle avoidance laser module is selectively arranged according to the usage mode requirements of the frame plate. Among them, the usage modes of the frame plate include a low-profile mode corresponding to the installation of the navigation laser module and a QR code version mode corresponding to the installation of the obstacle avoidance laser module;

[0008] Meanwhile, when the usage mode of the frame plate is in the low version mode or the QR code version mode, the front side of the rear through groove corresponding to the navigation laser module or the obstacle avoidance laser module that is not installed is physically isolated by a shielding member to prevent the formation of a cavity.

[0009] Preferably, navigation laser installation grooves for installing the navigation laser module are provided at both the left top corner and the right top corner of the bottom surface of the rear through groove.

[0010] Preferably, an obstacle avoidance laser installation groove for installing the obstacle avoidance laser module is provided at the middle of the bottom surface of the rear through groove.

[0011] Preferably, the shielding member is a sheet-shaped sheet metal part and is vertically arranged in the navigation laser installation groove or the obstacle avoidance laser installation groove.

[0012] Preferably, it further includes a front frame located at the front side of the frame plate, and basic navigation laser modules are provided at both the left top corner and the right top corner of the front frame.

[0013] Preferably, the front side of the rear through groove corresponding to the navigation laser module or the obstacle avoidance laser module that is not installed is physically isolated by a shielding member to prevent the formation of a cavity.

[0014] Compared with the related art, a frame plate with good obstacle avoidance effect provided by the present utility model has the following beneficial effects:

[0015] Through the flexible configuration of the rear through grooves on the rear frame and the ability to selectively install the navigation laser module or the obstacle avoidance laser module according to the usage mode of the frame plate, the present utility model allows the frame plate to freely switch between the low version mode and the QR code version mode, and at the same time ensures that the unused module area is physically isolated by a shielding member, effectively preventing the formation of a cavity, thereby significantly enhancing the versatility and safety of the frame plate.

[0027] Refer to Figures 2 to 7As shown in the figure, the present utility model provides a frame plate with good obstacle avoidance effect, including a rear frame 2 located at the rear side of the frame plate 1. A rear through groove 3 is horizontally and inwardly provided on the rear end face of the rear frame 2, and the rear through groove 3 runs through the rear frame 2 from left to right. In the rear through groove 3, a navigation laser module 4 or an obstacle avoidance laser module 6 is selectively provided according to the usage mode requirements of the frame plate 1. Among them, the usage mode of the frame plate 1 includes a low version mode corresponding to the installation of the navigation laser module 4 and a two-dimensional code version mode corresponding to the installation of the obstacle avoidance laser module 6;

[0028] Meanwhile, when the usage mode of the frame plate 1 is in the low version mode or the two-dimensional code version mode, the front of the rear through groove 3 corresponding to the unmounted navigation laser module 4 or obstacle avoidance laser module 6 is physically isolated by a shielding member 5 to avoid forming a cavity.

[0029] In this embodiment, navigation laser installation grooves 7 for installing the navigation laser module 4 are provided at both the left top corner and the right top corner of the bottom surface of the rear through groove 3.

[0030] In this embodiment, an obstacle avoidance laser installation groove 8 for installing the obstacle avoidance laser module 6 is provided at the middle of the bottom surface of the rear through groove 3.

[0031] In this embodiment, the shielding member 5 is a sheet-shaped sheet metal part and is vertically arranged in the navigation laser installation groove 7 or the obstacle avoidance laser installation groove 8.

[0032] In this embodiment, it further includes a front frame located at the front side of the frame plate 1. Basic navigation laser modules 4 are provided at both the left top corner and the right top corner of the front frame.

[0033] In this embodiment, the front of the rear through groove 3 corresponding to the unmounted navigation laser module 4 or obstacle avoidance laser module 6 is physically isolated by a shielding member 5 to avoid forming a cavity.

[0034] In the specific implementation process, when the low version mode is selected, first, the navigation laser module 4 is installed in the two navigation laser installation grooves 7 of the rear frame 2. Then, since the low version mode does not require the installation of the obstacle avoidance laser module 6, a shielding member 5 is installed in the obstacle avoidance laser installation groove 8, and the shielding member 5 is used to block the front of the rear through groove 3 corresponding to the obstacle avoidance laser installation groove 8. At this time, the navigation laser modules 4 installed in the two navigation laser installation grooves 7 of the rear frame 2 and the two basic navigation laser modules 4 of the front frame form a four-laser 360° obstacle avoidance. Compared with the previous models, there is no need to separately install a modular low-version lidar, reducing the structural part cost and shrinking the frame volume.

[0035] When the QR code version mode is selected, first install the obstacle avoidance laser module 6 in the obstacle avoidance laser installation groove 8 of the rear frame 2. Then, in the QR code version mode, there is no need to install the navigation laser module 4. Therefore, in order to prevent the obstacle avoidance laser of other vehicles from hitting the rear through slot 3 when multiple vehicles meet, causing the obstacle avoidance to fail, two shielding parts 5 are installed in the navigation laser installation groove 7, and the shielding parts 5 block the front of the rear through slot 3 corresponding to the navigation laser installation groove 7. At this time, the navigation laser module 4 installed in the obstacle avoidance laser installation groove 8 of the rear frame 2 and the two basic navigation laser modules 4 of the front frame form 360° obstacle avoidance, and the blind area area Figure 7 in the shaded part is smaller than the area of the original QR code version vehicle frame plate 1.

[0036] In summary, the QR code version mode and the low version mode completely share the same vehicle body. When it is the QR code version mode, the obstacle avoidance laser module 6 is installed in the middle of the rear of the vehicle, and the front of the rear through slot 3 corresponding to the navigation laser installation grooves 7 where the navigation laser modules 4 were originally installed on the left rear and right rear are sealed with the shielding parts 5 to avoid forming a hole and causing the obstacle avoidance to fail; when it is the low version mode, the navigation laser modules 4 installed on the left rear and right rear also have the function of obstacle avoidance, and the front of the rear through slot 3 corresponding to the obstacle avoidance laser installation groove 8 where the obstacle avoidance laser module 6 was originally installed is sealed with the shielding parts 5. Subsequently, the conversion of the vehicle frame plate 1 between the low version mode and the QR code version mode becomes simple and fast. There is no need to replace the entire vehicle frame, and only the module configuration needs to be adjusted, which greatly reduces the operation cost and improves the resource utilization rate.

[0037] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
