[0048] Reference Figures 1 to 4 The utility model provides a vehicle side panel pre-buckle automatic bending mechanism, which includes a fixing seat 10, a cylinder 20, a connecting rod 30, a bending assembly 40 and a limiting assembly 50.

[0049] The fixing seat 10 is used to be fixedly connected with other external components to install the utility model. The cylinder body of the cylinder 20 is hingedly connected to the fixing seat 10, and the piston rod of the cylinder 20 is hingedly connected to the connecting rod 30. The axial direction of the piston rod of the cylinder 20 is in the first horizontal direction, and the front end of the connecting rod 30 away from the cylinder 20 is a bent section 30a bent downward.

[0050] The bending assembly 40 includes a connecting shaft 41 and a connecting bearing 42. The axial direction of the connecting shaft 41 is the second horizontal direction. The connecting shaft 41 is fixedly connected to the bending section 30a of the connecting rod 30. The first horizontal direction is perpendicular to the second horizontal direction.

The connecting bearing 42 is sleeved outside the connecting shaft 41, the inner ring of the connecting bearing 42 is fixedly connected to the connecting shaft 41, and the outer ring of the connecting bearing 42 serves as a bending execution part.

[0051] The limiting assembly 50 is disposed between the fixing seat 10 and the connecting rod 30 , and is used to limit the movement stroke of the connecting rod 30 along the first horizontal direction.

[0052] When the utility model is used, Figure 5 and Figure 6 As shown, the automatic bending mechanism 1 for the pre-buckle of the automobile side panel is installed behind the pre-buckle 92 on the automobile side panel 91, and the bending assembly 40 is located directly behind the pre-buckle. The cylinder 20 drives the connecting rod 30, the bending assembly 40, and the limit assembly 50 to move forward along the first horizontal direction. After the connecting rod 30 moves forward a preset distance, it cannot move forward under the restriction of the limit assembly 50. At this time, the connecting bearing 42 of the bending assembly 40 abuts against the rear side of the pre-buckle 92. When the cylinder 20 continues to drive it to move forward, since the cylinder body of the cylinder 20 is hingedly connected to the fixed seat 10, the cylinder will rotate around the second horizontal direction. At this time, the bending assembly 40 at the bending section 30a moves downward, and the outer ring of the connecting bearing 42 will be as shown. Figure 7The vertical pre-fastener 92 shown is bent downward to about 180°, as shown in FIG. Figure 8 As shown, the pre-fastener 92 is in a bent state.

[0053] In some embodiments, there are two connecting bearings 42 , and the two connecting bearings 42 are arranged side by side along the second horizontal direction.

[0054] The number of the connecting bearings 42 can be reasonably set according to the specifications of the connecting bearings 42 and the width of the pre-fastener 92 .

[0056] Specifically, when the vertical section of the hinged connecting block 60 is hingedly connected to the piston rod of the cylinder 20 , the axial direction of the hinge axis is the second horizontal direction, so that the cylinder 20 can drive the bending assembly 40 to move downward together under the action of the limiting assembly 50 .

[0057] In some embodiments, reference Figures 1 to 4 The limiting assembly 50 includes a limiting groove 51 , a limiting shaft 52 and a limiting bearing 53 .

[0058] The length direction of the limiting groove 51 is the first horizontal direction, and the limiting groove 51 is arranged on the fixing seat 10.

The limiting bearing 53 is sleeved outside the limiting shaft 52, the inner ring of the limiting bearing 53 is fixedly connected to the limiting shaft 52, and the outer ring of the limiting bearing 53 is limited in the limiting groove 51 and can slide in the limiting groove 51 along the first horizontal direction.

[0059] Initially, the limiting bearing 53 is limited at the rear end of the limiting groove 51. As the piston rod of the cylinder 20 extends to the front end, it moves forward along the first horizontal direction with the connecting rod 30 and the limiting shaft 52. The limiting bearing 53 slides in the limiting groove 51 along the first horizontal direction. When it slides to the front end of the limiting groove 51, the limiting bearing 53 is limited, so that the connecting rod 30 is also limited from moving forward. At this time, when the cylinder 20 continues to move forward, it drives the bending component 40 at the front end of the connecting rod 30 to move downward.

[0060] In some embodiments, there are two limit bearings 53 , and the two limit bearings 53 are arranged side by side at a preset distance along the second horizontal direction.

[0061] The number of the limiting bearings 53 can be reasonably set according to the specifications of the limiting bearings 53 and the width of the limiting grooves 51 .

[0065] Initially, the guide bearing 73 is located at the rear end of the guide end surface 71. As the piston rod of the cylinder 20 extends to the front end, it moves forward along the first horizontal direction with the connecting rod 30 and the guide shaft 72. The guide bearing 73 slides along the first horizontal direction on the guide end surface 71 until the limit bearing 53 is limited, so that the connecting rod 30 is also limited to move forward. At this time, when the cylinder 20 continues to move forward, the bending assembly 40 at the front end of the connecting rod 30 moves downward, and the guide bearing 73 located at the front side of the limit assembly moves downward accordingly, while the guide bearing 73 located at the rear side of the limit assembly is lifted upward accordingly.

[0066] The guide component design of this embodiment can provide a better guiding effect for the bending component and the limit component when they move along the first horizontal direction, thereby improving the purpose of stable bending.

[0067] In some embodiments, there are two guide assemblies 70 , and the two guide assemblies 70 are respectively disposed on both sides of the limiting assembly 50 along the first horizontal direction.

[0070] When the piston rod of the cylinder 20 is hingedly connected to the connecting rod 30 via the hinged connection block 60 , the hinged connection block 60 is also disposed between the two connecting rods 30 .

[0071] In some embodiments, reference Figures 1 to 4 The connecting rod 30 includes a first straight rod 31 and a second straight rod 32. The length directions of the first straight rod 31 and the second straight rod 32 are both in the first horizontal direction.

The abutting block 82 is located below the bending assembly 40.

[0078] The abutment block 82 can be used to abut against the lower part of the pre-buckle of the automobile side panel, so that when the pre-buckle is bent, the automobile side panel can be better abutted and positioned to avoid the problem of inaccurate bending and positioning.

[0079] In some embodiments, reference Figure 5 and Figure 6 The automobile side panel pre-buckle automatic bending mechanism 1 of the utility model is used for bending the pre-buckle 92 of the automobile side panel 91.
