Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of anti-collision mechanisms, specifically relating to an anti-collision mechanism for the tail of a forklift-type mobile robot. Background Technology
[0002] The rear anti-collision mechanism for forklift mobile robots is a safety device specifically designed for the rear of automated guided vehicles (AGVs). Its main function is to protect the rear of the forklift from collision damage during operation, especially when reversing or turning. This anti-collision mechanism is designed to reduce collision accidents caused by operational errors or blind spots in warehouses or other working environments, thereby protecting the safety of equipment and operators, while reducing maintenance costs and improving work efficiency.
[0003] Existing forklift mobile robot tail collision avoidance mechanisms often exhibit poor adaptability due to insufficient flexibility in the coordination between structures. This inflexibility prevents the avoidance mechanism from accurately limiting the impact force when encountering collisions of different strengths and angles, which may cause damage to the avoidance mechanism itself and even affect the normal use of the AGV forklift. This limitation not only reduces the collision avoidance effect but may also increase maintenance costs and downtime, affecting overall operational efficiency and safety. Therefore, a new tail collision avoidance mechanism for forklift mobile robots is proposed. Utility Model Content

[0023] Example
[0024] Reference Figure 1-4 This embodiment of the present invention provides a tail collision avoidance mechanism for a forklift-type mobile robot, comprising:
[0025] The fork plate 101, the fixed frame 102 used in conjunction with the fork plate 101, the transmission assembly 103 movably installed on the inner wall of the fixed frame 102, the limiting assembly 104 fixedly installed on the side surface of the fixed frame 102, the auxiliary assembly 105 used in conjunction with the fork plate 101, the protective assembly 106 fixedly installed on the bottom of the fixed frame 102, and the rotating assembly 107 used in conjunction with the protective assembly 106.
[0026] The transmission assembly 103 includes a connecting frame 103a fixedly installed on the inner wall of the fixed frame 102, a protective plate 103b disposed on the side of the connecting frame 103a, an auxiliary belt 103c disposed on the side surface of the protective plate 103b, and a fixed plate 103d rotatably installed on the inner wall of the connecting frame 103a.
[0027] The transmission assembly 103 also includes a transmission belt 103e that contacts the fixed disk 103d, a transmission roller 103f that contacts the auxiliary belt 103c, and a drive motor 103g adapted to be installed on the side of the transmission roller 103f.
[0028] Specifically, the drive motor 103g in the transmission assembly 103 starts and transmits power to the fixed plate 103d through the transmission belt 103e and the transmission roller 103f, thereby driving the auxiliary belt 103c and the protective plate 103b to move. At the same time, the limiting assembly 104 restricts the items, and the auxiliary assembly 105 responds in conjunction with the fork plate 101 to pick up and put down the items. The protection provided by the protective assembly 106 at the bottom of the fixed frame 102 is further improved by the fixed installation between the structures of the protective assembly 106. The protective assembly 106 is made of metal. The transmission motor 107b in the rotating assembly 107 enables the protective assembly 106 to rotate flexibly through the transmission gear 107c and the rotating wheel 107d to absorb and disperse the collision energy, thereby effectively reducing the damage to the rear of the forklift.
[0029] The limiting assembly 104 includes a rotating wheel 104a, a movable frame 104b disposed on the side of the rotating wheel 104a, a limiting roller 104c inserted into the center of the movable frame 104b, and a limiting tooth 104d fixedly installed on the side surface of the movable frame 104b. The rotating wheel 104a and the limiting roller 104c are fixedly connected.
[0030] The auxiliary component 105 includes an auxiliary frame 105a, an auxiliary tooth 105b fixedly installed on the side surface of the auxiliary frame 105a, a rotating rod 105c inserted into the center of the auxiliary frame 105a, a rotating roller 105d rotatably installed on the inner surface of the fixed frame 102, and a bearing seat 105e sleeved on the side surface of the rotating roller 105d.
[0031] The protective assembly 106 includes a protective frame 106a, a protective plate 106b fixedly mounted on the side surface of the protective frame 106a, and bolts 106c fixedly mounted on the surface of the protective plate 106b.
[0032] The rotating assembly 107 includes a mounting frame 107a, a drive motor 107b adapted to be mounted on the side surface of the mounting frame 107a, a drive gear 107c fixedly mounted on the output end of the drive motor 107b, and a rotating wheel 107d fixedly connected to the side surface of the drive gear 107c.
[0033] It should be noted that the auxiliary frame 105a and auxiliary tooth 105b in the auxiliary component 105 respond to the auxiliary fork plate 101 through the cooperation of the rotating rod 105c and rotating roller 105d, and the support of the bearing seat 105e. The protective frame 106a and protective plate 106b of the protective component 106 are fixed by bolts 106c to provide bottom protection. The drive motor 107b in the rotating component 107 is started, and through the linkage of the drive gear 107c and the rotating wheel 107d, the protective component 106 can rotate adaptively according to the impact force, thereby effectively absorbing and mitigating the impact force and protecting the rear of the forklift from damage. The coordinated action of each component ensures the efficient operation of the anti-collision mechanism and the safety of the forklift.
[0034] Among them, the protective plate 106b of the protective component 106 is equipped with an ultrasonic sensor. When the forklift is running, if an object approaches the protective component 106, the ultrasonic sensor will transmit the signal to the alarm, causing the alarm to sound and alert the staff.
[0035] When the rear of the forklift is impacted during use, the protective frame 106a and protective plate 106b of the protective component 106 are fixed by bolts 106c to provide bottom-level protection. Meanwhile, the drive motor 107b in the rotating component 107, through the linkage of the drive gear 107c and the rotating wheel 107d, enables the protective component 106 to rotate flexibly, absorbing and dispersing the collision energy and reducing damage to the rear of the forklift. The anti-collision mechanism ensures the safe and efficient operation of the forklift during operation through the coordinated action of each component.
[0036] In summary, the metal material and structure of the protective component 106 enhance the protection capabilities of the forklift's rear end, reducing maintenance costs and downtime. The flexibility of the rotating component 107 improves the adaptability of the anti-collision mechanism to impacts of varying forces, effectively dispersing collision energy and protecting the forklift's rear end from severe damage. The synergistic effect of these components significantly improves the forklift's safety performance and work efficiency.
