[0024] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0025] First, combine Figures 1-8 This invention describes a bidirectional pallet shuttle vehicle for use in smart warehousing, which has a wide range of applications.

[0026] like Figures 1-8 As shown, a bidirectional pallet shuttle vehicle according to an embodiment of the present invention has a vehicle frame 100, a walking component, a lifting component, a detection component, and a shell component.

[0027] Specifically, such as Figures 1-8 As shown, in this embodiment, the vehicle frame 100 is equipped with an electrical box 101 and a battery 102. The vehicle frame 100 is composed of multiple side plates and a bottom plate. After precision machining, the multiple side plates are connected and fixed by locating pins and bolts, which can ensure the machining accuracy of each component in the vehicle frame 100 and the overall assembly accuracy, providing strong support for subsequent walking accuracy. The bottom plate is fixed to the bottom of the multiple side plates by countersunk screws.

[0028] Specifically, such as Figures 1-8As shown, in this embodiment, the walking assembly is mounted on the vehicle frame 100 and is used to drive the vehicle frame 100 to move. The walking assembly includes: two driving wheels 201, two driven wheels 202, a first driver 203, and two first drive shafts 204. The two driving wheels 201 are located on both sides of one end of the vehicle frame 100; the two driven wheels 202 are located on both sides of the other end of the vehicle frame 100; the first driver 203 is located inside the vehicle frame 100 and provides rotational driving force, and the first driver 203 is a combination of a motor and a reducer; one end of each of the two first drive shafts 204 is connected to the output end of the first driver 203, and the other end of each of the two first drive shafts 204 is connected to the two driving wheels 201 respectively. The two first drive shafts 204 rotate under the drive of the first driver 203, thereby driving the two driving wheels 201 to rotate, realizing the movement of the vehicle frame 100. This direct drive method reduces transmission noise and improves transmission efficiency by reducing mechanical structures.

[0029] Furthermore, such as Figures 1-8 As shown, the traveling assembly also includes four adjustment mechanisms and four guide wheels 506. The four adjustment mechanisms are located at the four corners of the vehicle frame 100; the four guide wheels 506 are respectively mounted on the four adjustment mechanisms. Under the action of the adjustment mechanisms, the position is finely adjusted. The guide wheels 506 are used to cooperate with the track on the external shelf to guide the shuttle when it moves. By finely adjusting the position, the track error can be accommodated.

[0030] In this embodiment, as Figure 5 As shown, one of the adjustment mechanisms includes: a fixing block 2051, two adjusting bolts 2052, an adjusting bracket 2053, and two locking holes 2054. The fixing block 2051 is mounted on the vehicle frame 100; the two adjusting bolts 2052 are threaded onto the fixing block 2051; the adjusting bracket 2053 has two slotted holes 20531, one end of the adjusting bracket 2053 contacts the two adjusting bolts 2052, and the other end of the adjusting bracket 2053 is connected to one of the guide wheels 506; the two locking holes 2054 are formed on the vehicle frame 100 and are positioned opposite to the two slotted holes 20531. The adjusting frame 2053 is fixed by tightening the locking parts on the two locking holes 2054 and the two waist holes 20531. When it is necessary to fine-tune the position of the guide wheel 506, the locking parts are loosened and the two adjusting bolts 2052 are turned to fine-tune the position of the adjusting frame 2053, thereby adjusting the position of the guide wheel 506. After the adjustment is in place, the locking parts are tightened again.

[0031] Specifically, such as Figures 1-8As shown, in this embodiment, the lifting assembly is mounted on the vehicle frame 100 for lifting cargo. The lifting assembly includes: a pair of support seats 301, a second drive shaft 302, a second driver 303, a chain drive mechanism 304, two commutators 305, two third drive shafts 306, four cam units, a top plate 308, and four guide units. A pair of support seats 301 are disposed within the vehicle frame 100; a second drive shaft 302 is rotatably connected to the pair of support seats 301, and both ends of the second drive shaft 302 pass through the pair of support seats 301; a second driver 303 is disposed within the vehicle frame 100, providing the driving force for rotational motion, and the second driver 303 is a combination of a servo motor and a reducer; the input end of a chain drive mechanism 304 is connected to the output end of the second driver 303, and the output end of the chain drive mechanism 304 is connected to the second drive shaft 302; two commutators 305 are symmetrically disposed within the vehicle frame 100, and the input ends of the two commutators 305 are respectively connected to both ends of the second drive shaft 302; one end of a third drive shaft 306 is connected to the output end of one of the commutators 305, and the other end of the third drive shaft 306 is connected to the vehicle body. The frame 100 is rotatably connected; one end of another third drive shaft 306 is connected to the output end of another commutator 305, and the other end of the third drive shaft 306 is rotatably connected to the vehicle frame 100. A support member is provided between the other end of the third drive shaft 306 and the vehicle frame 100 to support the other end of the third drive shaft 306. The other end of the third drive shaft 306 is rotatably connected to the support member; four cam units are respectively connected to the output ends of two commutators 305 and the other end of the third drive shaft 306; the top plate 308 is located on the top of the vehicle frame 100, and four top blocks 3081 are provided at the bottom of the top plate 308. The four top blocks 3081 are respectively connected to the four cam units; four guide units connect the top plate 308 and the vehicle frame 100 to guide the movement of the top plate 308. In this system, the chain drive mechanism 304 transmits power to the second drive 303 by controlling the operation of the second drive 303, causing the second drive shaft 302 to rotate. This power is then transmitted to the four cam units via two commutator 305s and two third drive shafts 306. The four cam units drive four top blocks 3081 to lift, which in turn lifts the top plate 308, thus achieving the purpose of smoothly lifting the cargo. It should be noted that the two commutator 305s are symmetrically installed within the vehicle frame 100, and the rotation direction output by the second drive 303 is opposite to that of the two commutator 305s. This effectively avoids unidirectional movement during cam unit lifting, prevents unilateral tilting of the lifting assembly, and avoids unilateral force on the four guide units, greatly extending the service life of the mechanical structure.

[0032] Furthermore, such as Figures 3-4As shown in Figure 7, in this embodiment, one of the cam units includes a transmission component 3071 and a cam 3072. The transmission component 3071 is disposed on the other end of the commutator 305 or the third drive shaft 306; the cam 3072 is rotatably connected to the transmission component 3071, and the cam 3072 contacts the top block 3081. The cam unit uses a specially shaped machined part to shorten the lever arm, making the force-bearing structure of the commutator 305 and the support better, thereby extending its service life. The stroke design of the cam unit: when the cam is at its highest lifting position, the cam 3072 is in a vertical state. The cam 3072 can perform a full circular motion during the lifting and lowering actions, avoiding accidents caused by over-lifting due to errors during debugging and later manual operation.

[0033] Furthermore, such as Figures 3-4 As shown in Figures 7 and 8, in this embodiment, the bottom of the top block 3081 has an arc-shaped structure, which can make the impact during the rotation of the cam 3072 more gentle, and at the same time, it can better handle the force of the cam unit rotation, thus making the structure more stable and reducing maintenance costs.

[0034] Furthermore, such as Figures 3-4 As shown in Figures 8 and 9, in this embodiment, one of the guide units includes a guide seat 3091 and a guide shaft 3092. The guide seat 3091 is disposed within the vehicle frame 100; the top of the guide shaft 3092 is connected to the top plate 308, and the bottom of the guide shaft 3092 passes through the guide seat 3091. A copper sleeve can be installed inside the guide seat 3091. The entire guide unit has a simple structure and effectively reduces the failure rate.

[0035] Specifically, such as Figures 3-4 As shown, in this embodiment, the detection component is mounted on the vehicle frame 100 and is used to detect the traveling component and related data during its operation. The detection component includes: a positioning barcode scanner 401, an overwidth detection photoelectric sensor 402, a radar detection component 403, a cargo detection photoelectric sensor 409, and a cargo detection photoelectric sensor 404. The positioning barcode scanner 401 is mounted on one side of the vehicle frame 100 and identifies the traveling direction of the shuttle by affixing a barcode to the inside of the shelf track; the overwidth detection photoelectric sensor 402 is mounted on the vehicle frame 100 and is used to detect whether the pallet or cargo is overwidth; the radar detection component 403 is mounted on the vehicle frame 100 and is used to detect whether there is a vehicle or foreign object in front of the direction of movement, ensuring operational safety; the cargo detection photoelectric sensor 409 is mounted on the vehicle frame 100 and is used to detect whether there is cargo in front of the direction of movement; the cargo detection photoelectric sensor 404 is mounted on the vehicle frame 100 and is used to detect whether the vehicle frame 100 is carrying cargo, preventing collisions and improving safety.

[0036] Specifically, such as Figures 1-2As shown, in this embodiment, the outer casing assembly is connected to the vehicle frame 100. The outer casing assembly includes: a front panel 501, a rear panel 502, two side panels 503, and anti-collision blocks 504. The front panel 501 is detachably mounted on the front of the vehicle frame 100; the rear panel 502 is detachably mounted on the rear of the vehicle frame 100; the two side panels 503 are detachably mounted on both sides of the vehicle frame 100; and the anti-collision blocks 504 are disposed on the front panel 501, the rear panel 502, and the two side panels 503. The outer casing assembly also includes a top cover 505, which is detachably mounted on the top plate 308. The top cover 505 is provided with a handle for easy removal during maintenance. After the top cover 505 is removed, the internal structure of the vehicle body can be seen, which greatly facilitates maintenance and shortens maintenance time. Battery replacement 102 can also be conveniently performed here.

[0037] Furthermore, such as Figures 3-4 As shown, in this embodiment of the invention, a bidirectional pallet shuttle further includes: an automatic charging brush plate 405, a status display light bar 406, a lifting height detection 407, and a lifting ring assembly 408. The automatic charging brush plate 405 is disposed on the vehicle frame 100; the status display light bar 406 is disposed on the vehicle frame 100 and is used to display the shuttle status: automatic, manual, and HMI; the lifting height detection 407 is disposed on the vehicle frame 100 and detects the lifting height of the top plate 308 in real time; the lifting ring assembly 408 is disposed on the vehicle frame 100 and is used when lifting the shuttle.

[0038] Above, refer to Figures 1-8 A bidirectional pallet shuttle vehicle according to an embodiment of the present invention is described. Equipped with a novel lifting mechanism and a low vehicle height, the bidirectional vehicle is characterized by convenient maintenance and repair, high efficiency in warehouse entry and exit, and is particularly suitable for scenarios with fewer types of goods and high frequency of warehouse entry and exit.
