[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] This utility model provides an extremely narrow fork arm structure for an AGV (Automated Guided Vehicle), such as... Figure 1 As shown, it includes: a lower cover 1 fork arm, an upper cover 2 fork arm, a scissor lift assembly 3 for extending and retracting the upper cover 2 fork arm, and a drive assembly 4 for driving the scissor lift assembly 3; one end of the scissor lift assembly 3 is hinged to the lower cover 1 fork arm, and the other end is hinged to the upper cover 2 fork arm; the drive assembly 4 is detachably connected to the lower cover 1 fork arm; the drive assembly 4 includes a drive member 41 and a direct drive module 42; the drive member 41 is detachably connected to the lower cover 1 fork arm; one end of the direct drive module 42 is fixedly connected to the output end of the drive member 41, and the other end is hinged to the scissor lift assembly 3.

[0025] In the specific implementation process, the direct drive module on the drive component 4 is directly connected to the scissor fork assembly 3, so that the driving force of the drive component 41 is directly transmitted to the scissor fork assembly 3. This optimizes the push rod support structure in the traditional fork arm assembly structure, making it more streamlined and the overall size of the fork arm narrower, so as to meet the working requirements of the fork arm picking up pallets with a smaller fork opening.

[0026] Furthermore, the direct drive module 42 includes: a transmission seat 421; the transmission seat 421 is fixedly connected to the output end of the drive member 41; a guide groove is provided on the lower cover 1 of the fork arm for guiding the transmission seat 421; the transmission seat 421 is slidably placed in the guide groove; the transmission seat 421 is hinged to the scissor fork assembly 3.

[0027] In Example 1, as Figure 2 As shown, the driving force of the driving component 41 can be directly transmitted to the scissor fork assembly 3 through the transmission seat 421, which is directly connected to the output end of the driving component 41. The guide groove set on the lower cover 1 of the fork arm guides the movement direction, preventing the transmission seat 421 from shifting position during movement, which could lead to component damage and ensure the stability of the fork arm extension and retraction.

[0028] Furthermore, the scissor fork assembly 3 includes: two active scissor forks 31 and two passive scissor forks 32; one end of each of the two active scissor forks 31 is hinged to the transmission seat 421, and the other end is hinged to the upper cover 2 of the fork arm; one end of each of the two passive scissor forks 32 is hinged to the lower cover 1 of the fork arm, and the other end is slidably connected to the upper cover 2 of the fork arm.

[0029] In Embodiment 2, the scissor fork assembly 3 includes two active scissor forks 31 and two driven scissor forks 32. One side of the active scissor fork 31 is hinged to the transmission seat 421, and the other side is hinged to the upper cover 2 of the fork arm. The driven scissor forks 32 are connected to the lower cover 1 of the fork arm through a sliding connection, and the other side is hinged to the upper cover 2 of the fork arm. When the transmission component drives the two active scissor forks 31 to extend and retract, the two driven scissor forks 32 extend and retract synchronously with the rise of the upper cover 2 of the fork arm, realizing the role of auxiliary support and making the extension and retraction movement of the upper cover 2 of the fork arm more stable.

[0030] Furthermore, a guide member 5 is provided on the lower cover 1 of the fork arm; the guide member 5 is detachably connected to the lower cover 1 of the fork arm.

[0031] Specifically, the guide component 5 in the traditional AGV is directly set in the lower cover 1 of the fork arm, so that it can not only realize the original function of fork arm guidance and limit, but also act as a wire groove inside the guide bar, further increasing the scene adaptability of the fork arm.

[0032] Furthermore, the drive component 41 includes: a lifting motor 411, a lead screw 412, and a lead screw nut 413; the lifting motor 411 is detachably connected to the lower cover 1 of the fork arm; one end of the lead screw is fixedly connected to the output end of the lifting motor 411, and the other end is detachably connected to the lead screw nut 413; the lead screw nut 413 is detachably connected to the direct drive module 42.

[0033] Specifically, the drive unit 41 includes a lifting motor 411 and a lead screw 412. The lifting motor 411 is located on one side of the lower cover 1 of the fork arm and has good load capacity and high efficiency. The lead screw 412 is connected to the output end of the motor, and on the other side it is detachably connected to the direct drive module 42 through a lead screw nut 413 to ensure the stability of the fork arm height under load.

[0034] Furthermore, the lower cover 1 of the fork arm is also provided with a fork tip obstacle detection sensor 6 for detecting obstacles between the upper cover 2 of the fork arm and the lower cover 1 of the fork arm.

[0035] Specifically, a fork tip obstacle detection sensor 6 is provided. This sensor uses a laser rangefinder to detect any obstacles between the upper cover 2 and the lower cover 1 of the fork arm in a timely manner, thereby reducing the possibility of accidents and improving safety.

[0036] Furthermore, a plurality of drive wheels 7 are provided for moving the lower cover 1 of the fork arm; the plurality of drive wheels 7 are detachably connected to the lower cover 1 of the fork arm.

[0037] Furthermore, the lower cover 1 of the fork arm is also provided with a detection element 8 for detecting the lifting height of the scissor fork assembly.

[0038] In a specific embodiment, the height of the passive scissor lift is directly detected by the detection element 8. The detected height is directly the height of the fork arm. Compared with other traditional types of sensors, the measured scissor lift extension height is more accurate.

[0039] This utility model discloses an ultra-narrow fork arm structure for an AGV (Automated Guided Vehicle). The ultra-narrow fork arm structure design effectively reduces the space occupied by the AGV during travel and material handling, improves its ability to enter and exit shelves or confined spaces, and can directly pick up pallets with small fork opening diameters, enhancing the AGV's adaptability under various task conditions. By setting a direct drive module 42 on the drive component 41, the push rod structure in the traditional AGV fork arm is improved, allowing its size to be made extremely narrow to adapt to the working conditions of picking up pallets with small fork opening diameters. The guide component 5 in the traditional AGV is directly set in the lower cover 1 of the fork arm, so that it can not only realize the original fork arm guiding and limiting function, but also act as a wire groove inside the guide bar, thereby realizing the functions that the traditional AGV should have.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
