Description

Technical Field

[0001] This utility model relates to the field of warehousing equipment technology, and in particular to a quick-connect AGV shell structure and an AGV vehicle including the structure. Background Technology

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

[0003] Existing AGV shell structures often use engineering plastics as the main material, while the body structure is made of metal. The metal body structure and the plastic shell structure are assembled with snaps. When the vehicle body is subjected to vibration, the stress concentration at the base of the plastic material can easily cause the assembly to break, resulting in the shell being discarded. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a quick-connect AGV shell structure and an AGV vehicle including the structure, so as to solve one or more problems in the prior art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A quick-connect AGV housing structure includes a front housing, a rear housing, a first chassis, and a second chassis. The front housing is interference-fitted with the first chassis via multiple limiting plugs, and the rear housing is interference-fitted with the second chassis via multiple limiting plugs. The quick-connect AGV housing structure also includes a third chassis, with the first chassis and the second chassis located at both ends of the third chassis and hinged to it respectively.

[0007] Furthermore, a locking block is provided on the inner side of the front shell and the rear shell respectively, and the locking block has an extension formed along the height direction of the front shell or the rear shell.

[0008] Furthermore, the limiting plug includes a plug body, a first slot for the extension to be inserted is opened at one end of the plug body, and a closing portion is provided at the other end of the plug body away from the first slot.

[0009] Furthermore, multiple second slots for the limiting insert are opened on both the first and second chassis.

[0010] Furthermore, a first light sheet and a second light sheet are respectively provided on the front cover, the first light sheet being connected to the first lampshade and the second light sheet being connected to the second lampshade.

[0011] Furthermore, a third lamp is provided on the rear housing, and the third lamp is connected to the third lamp cover; a first emergency stop switch, a power switch, a start / stop switch, a brake switch, a debugging interface, and a switching switch are also provided on the rear housing.

[0012] Furthermore, a first anti-collision strip is provided on the outer side of the first chassis away from the third chassis, and a first emergency stop switch, an RGBD camera, and a second lidar are respectively fixedly connected to the first chassis; the first chassis is fixedly connected to the front shell through multiple outer shell brackets.

[0013] Furthermore, a second anti-collision strip is provided on the outer side of the second chassis away from the third chassis. An automatic charging port, a first lidar, and a display screen are also provided on the second chassis. The second chassis is also fixed to the rear shell by multiple outer shell brackets.

[0014] Furthermore, there is a gap between the front shell and the rear shell.

[0015] Accordingly, this utility model also provides an AGV vehicle, which uses the above-mentioned AGV shell structure.

[0016] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0017] This invention eliminates the traditional method of directly connecting the plastic outer shell structure with the metal body structure. By adding a limiting plug and a first locking slot on the limiting plug, the front and rear shells are connected to the locking slot. At the same time, by utilizing the interference fit between the limiting plug and the chassis, the front and rear shells are connected to the chassis respectively, making it less likely for stress concentration to occur when the vehicle body is subjected to vibration, thus making it less likely for the outer shell to break.

[0018] Furthermore, by setting a constriction portion on the limiting plug and opening a second slot on the first and second chassis for the limiting plug to be inserted, and setting a chamfer on the second slot, it is easier for the limiting plug to be pressed down and inserted in the vertical direction, which not only reduces the assembly difficulty but also improves the assembly efficiency.

[0028] Please refer to Figure 1 A quick-connect AGV housing structure is disclosed, comprising a front housing 1, a rear housing 2, a first chassis 3, and a second chassis 4. The front housing 1 and rear housing 2 are both made of injection-molded ABS engineering plastic with a thickness of 3mm. The front housing 1 is interference-fitted with the first chassis 3 via multiple limiting plugs 26, and the rear housing 2 is interference-fitted with the second chassis 4 via multiple limiting plugs 26. The quick-connect AGV housing structure also includes a third chassis 5, with the first chassis 3 and the second chassis 4 located at both ends of the third chassis 5 and hinged to it respectively. Specifically, ... Figure 1 For example, the left end of the third chassis 5 is hinged to the first chassis 3, and the right end of the third chassis 5 is hinged to the second chassis 4. The third chassis 5 is hinged to the first chassis 3 and the second chassis 4 respectively to form a whole. The second chassis 4 and the third chassis 5 can rotate relative to the third chassis 5 respectively. The rotation angle is not less than 3° to achieve overall floating. The overall floating can realize the passability of the AGV vehicle body, so that it can pass through the road surface with slope.

[0029] Furthermore, there is a gap between the front shell 1 and the rear shell 2, the gap being 10-14mm. By setting the gap between the front shell 1 and the rear shell 2, the aforementioned rotation angle can be achieved to meet the floating characteristic requirements of the chassis.

[0030] For further details, please refer to... Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7A locking block 31 is provided on the inner side of the front shell 1 and the rear shell 2 respectively. There are multiple locking blocks 31.

The first emergency stop switch 21 is threadedly connected to the emergency stop switch bracket 20 through its own thread structure. The emergency stop switch bracket 20 is fixedly connected to the first chassis 3.

[0035] For further details, please refer to... Figure 1A third light element 10 is installed on the rear housing 2, and the third light element 10 is connected to the third light cover 11. The rear housing 2 also includes a second emergency stop switch 14, a power switch 15, a start / stop switch 16, a brake switch 17, a debugging interface 27, and a switching switch 28. The first emergency stop switch 21 and the second emergency stop switch 14 are used for emergency braking. The power switch 15 is used to turn the AGV on / off. The start / stop switch 16 is used to start or stop the vehicle's current task cycle when the power switch 15 is powered on and the manual / automatic mode switch is in the "automatic" position. The brake switch 17 enables the motor when the AGV is powered on, locking the moving parts of the vehicle. The debugging interface 27 is used for vehicle firmware upgrades and software debugging. The switching switch 28 is used for switching between manual and automatic operation modes.
