[0030] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0031] First, combine Figures 1-11 This invention describes an explosion-proof four-way shuttle vehicle for use in warehousing and transportation, which has a wide range of applications.

[0032] like Figures 1-11As shown, an explosion-proof four-way shuttle vehicle according to an embodiment of the present invention includes a vehicle frame 100, a first explosion-proof servo motor 201, a first rotating shaft 202, a transverse sprocket and chain transmission mechanism 203, a pair of universal couplings 204, a transverse wheel set, a pair of lifting modules 206, a second rotating shaft 207, a steering mechanism 208, a first longitudinal sprocket and chain transmission mechanism 209, a longitudinal wheel set, a second longitudinal sprocket and chain transmission mechanism 211, an explosion-proof power supply device 300, an explosion-proof electrical control device 400, and a wireless charging system.

[0033] Specifically, such as Figures 1-2 As shown in Figures 9-11, the first explosion-proof servo motor 201 is mounted on the vehicle frame 100; the first rotating shaft 202 is rotatably connected to the vehicle frame 100; the transverse sprocket and chain drive mechanism 203 connects the first explosion-proof servo motor 201 and the first rotating shaft 202, and is used to transmit the power of the first explosion-proof servo motor 201 to the first rotating shaft 202, driving the first rotating shaft 202 to rotate; one end of a pair of universal couplings 204 is respectively connected to both ends of the first rotating shaft 202; the transverse wheel set is liftably mounted on the vehicle frame 100, and the transverse wheel set is connected to the other end of the pair of universal couplings 204; a pair of lifting modules 206 are mounted on the vehicle frame 100 and connected to the transverse wheel set, and are used to drive the transverse wheel set to lift; the second rotating shaft 207 is rotatably connected to... On the vehicle frame 100, a steering mechanism 208 is connected to the output end of a first explosion-proof servo motor 201. The steering mechanism 208 is used to transmit the power of the first explosion-proof servo motor 201 to a first longitudinal sprocket and chain drive mechanism 209. The first longitudinal sprocket and chain drive mechanism 209 is connected to the steering mechanism 208 and a second rotating shaft 207. After receiving the power transmitted from the steering mechanism 208, the first longitudinal sprocket and chain drive mechanism 209 drives the second rotating shaft 207 to rotate. A longitudinal wheel set is set on the vehicle frame 100. A second longitudinal sprocket and chain drive mechanism 211 is connected to the longitudinal wheel set and the second rotating shaft 207. When the second rotating shaft 207 rotates, the second longitudinal sprocket and chain drive mechanism 211 transmits power to the longitudinal wheel set, causing the longitudinal wheel set to rotate.

[0034] Furthermore, such as Figures 1-2 As shown in Figures 9-11, the sprockets and chains in the transverse sprocket and chain transmission mechanism 203, the first longitudinal sprocket and chain transmission mechanism 209, and the second longitudinal sprocket and chain transmission mechanism 211 are made of alloy steel and have undergone surface hardening treatment. This not only improves wear resistance and strength but also reduces the coefficient of friction. Furthermore, the design ensures smooth transmission and reduces heat and sparks generated by friction.

[0035] Furthermore, such as Figures 1-2 As shown in Figures 9-11, the wheels in the horizontal and vertical wheelsets are made of stainless steel and are covered with an anti-static polyurethane layer to prevent static electricity and sparks from friction.

[0036] Furthermore, such as Figures 1-2 As shown in Figures 9-11, the lifting module 206 includes: a second explosion-proof servo motor 2061, two guide frames 2062, two guide blocks 2063, two fixed frames 2064, two gears 2065, a transmission structure 2066, and two racks 2067. The second explosion-proof servo motor 2061 is mounted on the vehicle frame 100; the two guide frames 2062 are located at the corners of the vehicle frame 100; the two guide blocks 2063 are slidably connected to the two guide frames 2062, and are connected to corresponding transverse wheel sets; the two fixed frames 2064 are mounted on the vehicle frame 100; the two gears 2065 are rotatably mounted within the two fixed frames 2064; the transmission structure 2066 connects the second explosion-proof servo motor 2061 and the two gears 2065, transmitting power from the second explosion-proof servo motor 2061 to the two gears 2065, driving them to rotate. The transmission structure 2066 can be any existing transmission structure 2066 that can realize power transmission; two racks 2067 are respectively guided and slidably set on two fixed frames 2064, and the two racks 2067 are respectively meshed with two gears 2065 in a one-to-one correspondence. The racks 2067 pass through the corresponding fixed frames 2064, and the racks 2067 are connected to the corresponding guide blocks 2063 through the connecting plate 2068. When the gears 2065 rotate, they will drive the corresponding racks 2067 to rise and fall on the fixed frames 2064, thereby driving the corresponding guide blocks 2063 to rise and fall through the connecting plate 2068, thereby driving the transverse wheel set to rise and fall.

[0037] It should be noted that the first explosion-proof servo motor 201 and the second explosion-proof servo motor 2061 are drive motors specifically designed for explosion-proof environments. The motor housings are made of explosion-proof materials, and the internal electrical components undergo special treatment to effectively prevent the generation of electrical sparks. For example, by using explosion-proof motors, the housing can withstand the potential internal explosion pressure and prevent the spread of explosion flames to the surrounding environment. The motor junction boxes employ a sealed design, and all terminals undergo rigorous insulation treatment to ensure that no leakage or electrical sparks occur during operation.

[0038] Furthermore, such as Figures 1-2 As shown in Figures 9-11, a lifting block is provided on the connecting plate 2068. The lifting block moves up and down with the connecting plate 2068 to support external items.

[0039] Furthermore, such as Figures 1-2As shown in Figures 9-11, the rack 2067 is made of stainless steel, and the gear 2065 is made of alloy steel. The surfaces are hardened to ensure smooth transmission and reduce heat and sparks generated by friction. Furthermore, for the lubrication of the transmission components, an explosion-proof lubricant is used to ensure that no safety issues arise during lubrication.

[0040] Furthermore, such as Figure 1 , 9 As shown, an explosion-proof four-way shuttle vehicle according to an embodiment of the present invention further includes: a lifting ring 600, which is disposed at the four corners of the vehicle frame 100, thereby facilitating the lifting and transportation of the shuttle vehicle.

[0041] Furthermore, such as Figure 1 , 9 As shown, the lateral wheel assembly includes: two lateral drive wheels 2051, two lateral driven wheels 2052, and four lateral follower wheels 2053. The two lateral drive wheels 2051 are rotatably connected to one of the guide blocks 2063 in a pair of lifting modules, and are respectively connected to the other end of a pair of universal couplings 204. The two lateral driven wheels 2052 are rotatably connected to one of the guide blocks 2063 in a pair of lifting modules. A sprocket and chain drive mechanism 2054 connects the lateral drive wheels 2051 and lateral driven wheels 2052 located on the same side of the vehicle frame 100. The two pairs of lateral follower wheels 2053 are rotatably connected to the other guide block 2063 in a pair of lifting modules. The two lateral drive wheels 2051 are driven to rotate by the pair of universal couplings 204, thereby driving the two lateral driven wheels 2052 to rotate via the sprocket and chain drive mechanism 2054, and the two pairs of lateral follower wheels 2053 follow suit.

[0042] Furthermore, such as Figure 1 , 9 As shown, the longitudinal wheel assembly includes two pairs of longitudinal drive wheels 2101 and two pairs of longitudinal driven wheels 2102. The two pairs of longitudinal drive wheels 2101 are rotatably connected to one end of each side of the vehicle frame 100, and each pair of longitudinal drive wheels 2101 is connected to a corresponding second longitudinal sprocket and chain drive mechanism 211; the two pairs of longitudinal driven wheels 2102 are rotatably connected to the other end of each side of the vehicle frame 100. The second longitudinal sprocket and chain drive mechanism 211 transmits power from the second shaft 207 to the two pairs of longitudinal drive wheels 2101, causing the two pairs of longitudinal drive wheels 2101 to rotate, and the two pairs of longitudinal driven wheels 2102 follow suit.

[0043] Specifically, such as Figure 1 , 3As shown in Figure 4, the explosion-proof power supply unit 300 is mounted on the vehicle frame 100 and is used to provide power. The explosion-proof power supply unit 300 includes: a battery compartment 303 301, a cover 302, and a battery 303. The battery compartment 303 301 is mounted on the vehicle frame 100 and is designed according to explosion-proof requirements. Both the cover 302 and the battery compartment 303 301 are made of alloy steel. The cover 302 is secured to the battery compartment 303 301 with bolts and nuts. The battery 303 is located inside the battery compartment 303 301. It should be noted that the battery 303 is composed of lithium iron phosphate cells connected in series and parallel in a 1P15S configuration. The battery compartment 303 301 also contains a power system. The power system uses a BMS to intelligently manage the battery pack 303, and collects real-time data on charging, discharging, overcurrent, short circuit, and temperature, and provides protection based on set thresholds. The lithium iron phosphate batteries used in the power system employ advanced battery manufacturing processes, exhibiting characteristics such as good consistency, high specific energy, long lifespan, safety and reliability, and a wide operating temperature range. The battery management system (BMS) is the collective term for the circuit system that ensures the safe and reliable operation of individual lithium battery cells and the battery pack as a whole. This system collects parameters such as the total voltage of the lithium battery pack, individual cell voltage, charge / discharge current, and ambient battery temperature, monitoring the charging and discharging process and status of the lithium batteries, and providing effective protection and alarm functions. It typically consists of data acquisition, monitoring, and protection circuits, electrical components, communication interfaces, thermal management, and data transmission.

[0044] Specifically, such as Figure 1 , 5 As shown in Figure 6, the explosion-proof electrical control device 400 is mounted on the vehicle frame 100 and is used for electrical control. The explosion-proof electrical control device 400 includes a control box 401 and a control unit 402. The control box 401 is mounted on the vehicle frame 100 and is made of a high-strength, corrosion-resistant alloy material with good explosion-proof performance. It is not only lightweight, which facilitates the flexible operation of the shuttle, but also has excellent strength and explosion-proof performance. The control unit 402 is located inside the control box 401 and is designed for explosion-proof operation. All electrical components, such as controllers, sensors, relays, servo motor drivers, and contactors, are explosion-proof products. These explosion-proof electrical components have a specially designed structure to effectively prevent the generation of electrical sparks and high temperatures. The sensors adopt an isolated design, isolating the sensitive elements from external circuits to prevent external interference signals from causing electrical sparks.

[0045] Specifically, such as Figure 1 , 7As shown in Figure 8, the wireless charging system is used to wirelessly charge the explosion-proof power supply device 300. The wireless charging system includes a wireless receiver 501, which is connected to the explosion-proof power supply device 300. In use, a wireless charging base station is set up inside the warehouse. When the shuttle needs charging, it simply drives to the front of the wireless charging base station to automatically charge. The wireless charging technology uses the principle of electromagnetic induction, transmitting electrical energy to the shuttle's battery 303 through magnetic field coupling between the wireless transmitter 502 and the wireless receiver 501. This charging method avoids the electrical sparks that may occur when plugging and unplugging in traditional wired charging methods, improving the safety of the charging process. For example, the transmission power and charging efficiency of the wireless charging base station can be adjusted according to the capacity and charging needs of the shuttle's battery 303 to ensure fast and efficient charging of the shuttle. Simultaneously, the wireless charging system also has overvoltage, overcurrent, and overheat protection functions to ensure the safety and reliability of the charging process.

[0046] In operation, the first explosion-proof servo motor 201 operates, transmitting power to the first rotating shaft 202 via the transverse sprocket and chain transmission mechanism 203. This drives the first rotating shaft 202 to move, and then the first rotating shaft 202, through a pair of universal couplings 204, transmits power to the transverse wheel set, allowing the shuttle to move laterally on the transverse guide rail. During reversal, the second explosion-proof servo motor operates, transmitting power to the gear 2065 via the transmission structure 2066. The gear 2065 rotates, causing the rack 2067 to rise along with it. Through the connecting plate 2068, this rises the corresponding guide block 2063, causing the transverse wheel set to rise for the first time. Once a suitable height is reached, the rising stops, at which point the longitudinal wheel set contacts the longitudinal guide rail, achieving [the desired movement]. The horizontal and vertical reversal is initiated by the first explosion-proof servo motor 201, which transmits power to the second rotating shaft 207 via the steering structure and the first longitudinal sprocket and chain transmission mechanism 209. The second rotating shaft 207 rotates, transmitting power to the longitudinal wheel set via the second longitudinal sprocket and chain transmission mechanism 211, thus enabling longitudinal movement. When the vehicle reaches the area below the cargo to be transported, the second explosion-proof servo motor 2061 operates, transmitting power to the gear 2065 via the transmission structure 2066. The gear 2065 rotates, and the rack 2067 rises along with it. Through the connecting plate 2068, the corresponding guide block 2063 rises, thereby causing the horizontal wheel set to rise a second time, and the lifting block rises a second time to contact the cargo.

[0047] Above, refer to Figures 1-11 An explosion-proof four-way shuttle vehicle according to an embodiment of the present invention is described, which has the following beneficial effects: Compared to traditional four-way shuttles, the explosion-proof four-way shuttle of this invention features comprehensive explosion-proof design from its overall structure to each system, employing a variety of advanced explosion-proof technologies and measures, resulting in a significant improvement in its explosion-proof performance. Traditional shuttles may only provide simple explosion-proof treatment for some electrical components, which cannot meet the requirements of high-risk explosion-proof environments.

[0048] The shuttle of this invention can be used in various flammable and explosive environments, and its application range far exceeds that of traditional four-way shuttles. It can provide safe and efficient solutions for logistics and warehousing operations in a wider range of fields.
