[0002] A child safety seat is a seat designed for children of different weights and installed in a car to effectively improve the safety of children. However, it is difficult to adjust the angle of a conventional child safety seat. Children who sit in a child safety seat will become uncomfortable and make noises because they cannot sit for a long time. They hope that their guardians can take them out of the child safety seat. To this end, relevant personnel have recently developed a sliding child safety seat, such as Figure 1 and 2 As shown, it includes a positioning seat 101 and a seat 102, a sliding structure is arranged between the seat 102 and the positioning seat 101, and a sliding knob 103 is installed on the bottom of the side of the seat 102. The sliding structure is driven by the rotation of the sliding knob 103 to adjust the angle of the seat 102, so that the child can adjust between sitting and lying (or half-lying), avoiding the child from being noisy due to sitting for a long time. Since the sliding child safety seat has only been around for a short time, there is no relevant testing equipment to test the durability of the sliding structure of the child safety seat, which cannot ensure the rights and interests of users and needs to be developed urgently. Summary of the invention

[0003] A technical problem to be solved by the present application is to overcome the defects of the above related technologies and provide a child safety seat sliding durability detection device capable of detecting the sliding durability of a child safety seat.

The mechanical arm is installed on the side of the frame close to the child safety seat where the sliding knob is set. A camera is provided on the mechanical arm or the frame, and the camera, the mechanical arm, the rotating motor and the sliding knob locking claw are electrically connected to the controller respectively.

[0005] Compared with the related art, the present invention has the following advantages: the sliding knob of the child safety seat is locked by a camera, and the controller controls the mechanical arm to swing so that the sliding knob locking claw moves toward the sliding knob, and the sliding knob locking claw grasps the sliding knob. Under the rotation drive of the rotating motor, the sliding knob locking claw twists the sliding knob to rotate so that the seat slides on the positioning seat, and the swing of the mechanical arm enables the sliding knob locking claw to slide smoothly along with the seat, thereby detecting the sliding durability of the child safety seat when the seat slides back and forth.

[0006] Preferably, the sliding knob locking claw includes a push rod motor and a plurality of grab arms hinged on the push rod motor cylinder body, the tail end of the grab arm is hinged to the push rod of the push rod motor, and the outer end of the grab arm is retracted to grasp the sliding knob or spreads out to release the sliding knob under the movement of the push rod.

[0007] As an improvement, a reduction gear set is provided between the sliding knob locking claw and the rotating motor to reduce the rotation speed to increase the torque and ensure the sliding stability of the child safety seat.

[0008] As an improvement, the controller is provided with a seat sliding trajectory calculation module, which is used to calculate the sliding curve of the seat on the positioning seat according to the seat sliding trajectory recorded by the camera. By calculating the sliding curve of the seat on the positioning seat, the controller can accurately control the cooperation of the robot arm. BRIEF DESCRIPTION OF THE DRAWINGS
