[0013] like Figures 1 to 6 As shown, an assembly aid for a car roof and a rear top light reinforcement frame, a workbench 10 for placing the rear top light reinforcement frame A is provided on a frame 20, the workbench 10 and the lower end of the swing rod 30 are hinged by a horizontal first hinge shaft 31, a swing rod 30 is provided at each frame of the rear top light reinforcement frame A, a movable frame 40 is provided above the workbench 10, and when the movable frame 40 moves up and down, the upper ends of the swing rods 30 are driven to approach and close together or to drive the upper ends of the swing rods 30 away from each other, when the upper ends of the swing rods 30 are away from each other, the clamping feet A1 of the rear top light reinforcement frame A are driven to bend toward the vehicle roof B, and when the upper ends of the swing rods 30 are approached and closed together, the projections of the movable frame 40 and the swing rod 30 on the horizontal plane are located within the frame range of the rear top light reinforcement frame A.

[0014] In the above scheme, a movable frame 40 is provided above the workbench 10. When the movable frame 40 moves upward, the upper ends of the swing rods 30 are close to each other. At this time, the projections of the movable frame 40 and the swing rods 30 on the horizontal plane are located within the frame range of the rear top light reinforcement frame A, which can ensure that the rear top light reinforcement frame A and the vehicle ceiling B are placed on the workbench 10. When the movable frame 40 moves downward, the upper ends of the swing rods 30 move away from each other. At this time, the lower end of the swing rod 30 will gradually tilt from a vertical state, thereby driving the clamping foot A1 of the rear top light reinforcement frame A to bend toward the vehicle ceiling B, so that the clamping foot A1 at each frame of the rear top light reinforcement frame A can be evenly bent toward the opening position of the vehicle ceiling B and clamped at the opening position of the vehicle ceiling B.

[0015] During the specific working process, the operator needs to first move the movable frame 40 upward so that the upper ends of the swing rods 30 are close to each other, and then place the rear top light reinforcement frame A on the workbench 10, and then align the opening area of ​​the vehicle roof B with the rear top light reinforcement frame A and place it on the workbench 10, so as to ensure that the top light reinforcement frame A is placed in the opening area of ​​the ceiling B, and then move the movable frame 40 downward so that the upper ends of the swing rods 30 are away from each other, and the rod body of the swing rod 30 is used to bend and press the clamping feet A1 of the rear top light reinforcement frame A, so as to drive the clamping feet A1 at each frame of the rear top light reinforcement frame A to be evenly bent toward the opening area of ​​the vehicle ceiling B. After the rear top light reinforcement frame A and the vehicle ceiling B are stably connected, the movable frame 40 is moved upward so that the upper ends of the swing rods 30 are close to each other, and the installed vehicle ceiling B can be taken out.

[0016] Furthermore, the other end of the swing rod 30 away from the first hinge axis 31 is hingedly connected to the swing rod 33 by the second hinge axis 32, and the other end of the swing rod 33 is hingedly connected to the movable frame 40 by the third hinge axis 34. The first hinge axis 31, the second hinge axis 32 and the third hinge axis 34 are arranged parallel to each other. When the movable frame 40 moves up and down, the hinged connections between each swing rod 30 and the swing rod 33 are driven to approach or move away from each other.

[0017] In the above scheme, the lower end of the swing rod 30 is hinged to the workbench 10 through the first hinge axis 31, and the other end of the swing rod 30 is hinged to the rocker arm 33 through the second hinge axis 32. The other end of the rocker arm 33 is hinged to the movable frame 40 through the third hinge axis 34. When the movable frame 40 moves up and down, the movable frame 40 drives the lower ends of the rocker arm 33 to move away from each other, that is, the upper ends of the swing rod 30 move away from each other, so that the rod body of the swing rod 30 bends and presses the clamping foot A1 of the ceiling light reinforcement frame A. At the same time, the first hinge axis 31, the second hinge axis 32 and the third hinge axis 34 are arranged parallel to each other, and the swinging surfaces of the swing rod 30 and the rocker arm 33 are parallel or coplanar, and the swinging surfaces of the swing rod 30 and the rocker arm 33 are located on the plumb plane.

[0018] Preferably, a positioning boss 11 protrudes upward from the upper surface of the workbench 10 , the size of the positioning boss 11 is consistent with the size of the inner opening A2 of the rear top light reinforcement frame A, and the height of the positioning boss 11 is consistent with the frame height of the rear top light reinforcement frame A.

[0019] In the above scheme, the rear top light reinforcement frame A is placed on the positioning boss 11 protruding upward from the upper surface of the workbench 10, and the lower end of the swing rod 30 is hinged to the positioning boss 11 through the first hinge shaft 31. The size of the positioning boss 11 is consistent with the size of the inner opening A2 of the rear top light reinforcement frame A, ensuring that the posture of the rear top light reinforcement frame A is stable during the bending process of the clamping foot A1 of the rear top light reinforcement frame A. At the same time, the height of the positioning boss 11 is consistent with the frame height of the rear top light reinforcement frame A, ensuring that the clamping foot A1 can be bent from the root, avoiding the existence of a gap between the rear top light reinforcement frame A and the vehicle ceiling B.

[0020] Furthermore, the length of the swing rod 33 is greater than that of the swing rod 30, so that when the downward displacement stroke of the movable frame 40 is small, the swing rod 33 can drive the swing rod 30 to swing 90° when the swing angle is small, that is, the swing rod 30 swings from the upright state to the horizontal state, see Figure 6 .

[0021] Furthermore, a driving cylinder 50 is provided in the frame 20 at the lower part of the workbench 10 , and a driving rod 51 of the driving cylinder 50 passes through the table surface of the workbench 10 and is fixedly connected to the movable frame 40 .

[0022] In the above scheme, the movable frame 40 moves up and down under the drive of the driving cylinder 50, and the upper end of the driving rod 51 is fixedly connected to the movable frame 40, thereby driving the movable frame 40 to move up and down. At the same time, the driving rod 51 of the driving cylinder 50 passes through the table surface of the workbench 10, and the workbench 10 plays a limiting and guiding role for the driving cylinder 50, ensuring that the movable frame 40 can stably move up and down.

[0023] Preferably, in order to facilitate the swing rod 30 to bend the clamping foot A1 of the rear top light reinforcement frame A, the swing rod 33 and the swing rod 30 are square columns, ensuring that there is surface contact between the swing rod 30 and the clamping foot A1 of the rear top light reinforcement frame A, with a larger pressing area.

[0024] Referring to the accompanying drawings, it should be noted that the setting positions and the number of the swing rods 33 and 30 correspond to the setting positions and the number of the clamping feet A1 of the rear ceiling light reinforcement frame A. Figure 2 The clamping pins A1 of the rear top light reinforcement frame A shown are arranged at four edges of the mouth area of ​​the rear top light reinforcement frame A, two of which are arranged at the left edge, for a total of seven clamping pins A1. Therefore, in the example provided in the present application, seven matching rocker arms 33 and rocker arms 30 are arranged. Of course, the two clamping pins A1 arranged at the left edge are close to each other, so the bending operation can be completed by a pair of matching rocker arms 33 and rocker arms 30, wherein the correspondingly arranged first hinge shaft 31, second hinge shaft 32 and third hinge shaft 34 are parallel to the four edges of the mouth area of ​​the rear top light reinforcement frame A where they are located.
