It also includes a drive assembly for moving the frame assembly and a lifting assembly for lifting goods. The drive assembly, lifting assembly, battery assembly, and communication assembly are all connected to the control assembly. The AGV is composed of multiple modules, exhibiting a high degree of modularity. Each mechanism is an independent module, increasing the interchangeability of the device and facilitating installation and maintenance. The modular design also makes explosion-proof treatment of the AGV easier.

[0005] However, the electronic components of the control system in the aforementioned explosion-proof AGV are all enclosed in an explosion-proof control cabinet. During maintenance and repair, the entire control system needs to be removed and disassembled, which is time-consuming and laborious. The battery pack also lacks convenient design for charging and replacement, leaving considerable room for improvement. Utility Model Content

[0006] To address the problems of inconvenient structural inspection and maintenance of common explosion-proof AGVs on the market, time-consuming and laborious charging and battery replacement, and the lack of an optimized structure that balances protection performance and ease of operation, we provide explosion-proof AGVs.

A locking lever is located at the opening of the battery slot, and a flame-retardant connector is located on the outside of the battery explosion-proof box, which is electrically connected to the electronic control components.

[0008] Furthermore, the hinge door is provided with an upwardly inclined protective groove, and the explosion-proof touch screen is installed in the protective groove.

[0009] Furthermore, the explosion-proof control box is provided with support columns on both sides, and the support columns are detachably connected to the drive chassis by bolts.

[0010] Furthermore, the bottom of the battery slot is provided with multiple ball bearing rollers, and multiple horizontal pulleys are arranged from the outside to the inside on the left and right sides.

[0011] Furthermore, the battery explosion-proof box includes a top cover and a battery box body that are interlocked. The battery box body is equipped with a storage battery and a circuit breaker. A protective frame is connected to the outside of the storage battery. A flame-retardant connector is connected to the storage battery through the circuit breaker.

[0026] like Figure 1-4 As shown, this embodiment provides an explosion-proof AGV trolley, including a drive chassis 1. A protective housing 2 is installed on the drive chassis 1. A control explosion-proof box 3 is provided at the front end of the protective housing 2, and a battery slot 4 is provided at the rear end. A battery explosion-proof box 5 is slidably fitted in the battery slot 4. A hinge door 301 is provided at the front end of the control explosion-proof box 3. An explosion-proof touch screen 6 is provided on the hinge door 301. The explosion-proof touch screen 6 is electrically connected to the electronic control component 302 inside the control explosion-proof box 3. A locking lever 7 is provided at the opening of the battery slot 4. A flame-retardant connector 501 is provided on the outside of the battery explosion-proof box 5. The flame-retardant connector 501 is electrically connected to the electronic control component 302.

[0027] In actual use, the explosion-proof box 3 can be easily opened and closed via the hinge door 301, allowing for quick maintenance and repair of the electrical control components 302 inside the explosion-proof box 3. The explosion-proof touchscreen 6 facilitates easy viewing and setting of the AGV's operating status by staff. The battery slot 4 houses the battery explosion-proof box 5 via a locking lever 7. The battery explosion-proof box 5 can be quickly removed and placed from the battery slot 4 using the locking lever 7, making it convenient for staff to remove the battery explosion-proof box 5 for charging or directly replace it with a fully charged battery explosion-proof box 5 for use in the AGV, reducing the difficulty of use and maintenance.

[0028] The hinge door 301 is provided with an upwardly tilted protective groove 303, in which the explosion-proof touch screen 6 is installed. The recessed explosion-proof touch screen 6 is not easily damaged by impact, and since the height of AGV vehicles is generally very low, the upward tilting design of the screen makes it convenient for staff to view, which is ergonomic.

[0029] The explosion-proof control box 3 is provided with support columns 8 on both sides, and the support columns 8 are detachably connected to the drive chassis 1 by bolts. The support columns 8 can further improve the structural stability of the explosion-proof control box 3 and the drive chassis 1.

[0030] The bottom of the battery slot 4 is provided with multiple ball bearing rollers 401, and multiple horizontal pulleys 402 are arranged from the outside to the inside on the left and right sides. The ball bearing rollers 401 and the horizontal pulleys 402 can significantly reduce the sliding friction resistance of the battery explosion-proof box 5 in the battery slot 4, making it extremely easy and smooth to pick up and put in the battery explosion-proof box 5.

[0031] The battery explosion-proof enclosure 5 includes an interlocking top cover 502 and a battery housing 503. A battery 504 and a circuit breaker 505 are housed within the battery housing 503. A protective frame 506 is connected to the outside of the battery 504. A flame-retardant connector 501 connects to the battery 504 via the circuit breaker 505. The detachable battery explosion-proof enclosure 5 facilitates the installation of internal equipment. The protective frame 506 enhances the physical protection of the battery 504, and the circuit breaker 505 prevents damage to the battery 504 from current surges.

[0032] The battery explosion-proof box 5 is provided with multiple folding handles 9 on its side. The folding handles 9 make it convenient for staff to pick up and put down the battery explosion-proof box 5, and will not obstruct the insertion of the battery explosion-proof box 5 into the battery slot 4 due to the protruding handles.

[0033] The front end of the battery explosion-proof box 5 is provided with a lever holder 701 corresponding to the locking lever 7, and a protective door 403 is provided on the outside of the opening of the battery slot 4. The lever holder 701 can cooperate with the locking lever 7 to lock the battery explosion-proof box 5, preventing the battery explosion-proof box 5 from loosening and making abnormal noise when the AGV moves. In this embodiment, the protective door 403 is located at the rear end of the protective housing 2, isolating the battery slot 4 and the battery explosion-proof box 5 from the outside world and preventing the internal equipment from being damaged by external impacts.

[0034] The protective housing 2 is equipped with a self-destructing fire extinguishing ball 10. The self-destructing fire extinguishing ball 10 can be a commercially available product (such as an AFO automatic fire extinguishing bomb), which will automatically detonate when the AGV is near a high-temperature heat source such as a flame or when the internal battery overheats, helping to reduce property damage in the event of an accident.

[0035] The battery explosion-proof box 5 is electrically connected to a coulomb counter 11, which is installed at the front end of the protective housing 2. The coulomb counter 11 is a commonly used battery power monitoring component on the market, which allows staff to check the remaining power of the AGV vehicle battery at any time so that it can be charged in a timely manner.

[0036] The flame-retardant connector 501 and the battery slot 4 have the same opening orientation. The outward-facing flame-retardant connector 501 facilitates the operation of workers to connect and disconnect the AGV vehicle power supply line plugged into the flame-retardant connector 501, which is ergonomic.

[0037] The above description is a further detailed explanation of the present utility model in conjunction with specific preferred embodiments. It should not be assumed that the specific implementation of the present utility model is limited to these descriptions. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present utility model.
