[0038] The edge covering equipment 100 and the door structure 200 provided by the embodiments of the present application will be described.
[0039] The edge covering device 100 provided by the embodiment of the present application can be used for covering the outer plate of the door structure 200 of the automobile, or covering the plate of other structure of the automobile, or covering the plate of non-automobile.
[0040] Please refer to Figs. 1 to 3 As shown in the figure, the edge covering device 100 provided by the embodiment of the present application comprises a support 101, a first driving mechanism 102 and a lever 103. The lever 103 is rotationally connected to the support 101, and the lever 103 has a first end 1031 and a second end 1032 which are arranged on the two sides of the support 101 respectively. The second end 1032 is used to enter the gap 203 between the first plate 201 and the second plate 202 and push the edge 2011 of the first plate 201 to perform edge turning. The first driving mechanism 102 has a driving part 1022, and the first end 1031 is rotationally connected to the driving part 1022 and drives the second end 1032 to enter the gap 203 and push the edge 2011 to perform edge turning under the driving of the driving part 1022.
[0041] The support 101 is a seat structure, which can be a solid structure or a frame structure. The seat structure has a relatively stable supporting effect and can provide lever support for the lever 103.
[0042] The lever 103 is a long strip structure, and its cross section can be of any shape. The two ends of the long strip structure are respectively the first end 1031 and the second end 1032. Any region of the long strip structure between the first end 1031 and the second end 1032 can be used as a region for rotationally connecting the lever 103.
[0043] The edge 2011 of the first plate 201 is the outermost part of the first plate 201. During the process of the second end 1032 entering the gap 203, the edge 2011 is continuously pushed by the second end 1032 and an angle is generated between the edge 2011 and the innermost part of the first plate 201 which is located inside the outermost part. The angle is continuously reduced by pushing the edge 2011, and finally the angle between the edge 2011 and the innermost part tends to zero, so that the edge turning is completed and the edge 2011 forms the edge covering of the first plate 201.
[0044] Compared with the prior art, the edge covering device 100 provided in the application, wherein the support 101 provides a lever support, the lever member 103 is rotationally connected to the support 101, the lever member 103 has a first end portion 1031 and a second end portion 1032 arranged on two sides of the support 101, the first end portion 1031 and the second end portion 1032 can be pryed with each other based on the rotational connection position of the lever member 103, the first driving mechanism 102 has a driving portion 1022, the first end portion 1031 is rotationally connected to the driving portion 1022 and drives the second end portion 1032 under the driving of the driving portion 1022, and the second end portion 1032 enters the gap 203 between the first plate 201 and the second plate 202 and pushes the edge 2011 of the first plate 201 to be flanged under the linkage action.
[0045] The edge covering device 100 provided in the application uses the lever action to transmit the power of the first driving mechanism 102 to the second end portion 1032 of the lever member 103, the second end portion 1032 can be accurately controlled to enter the gap 203 between the first plate 201 and the second plate 202 and push the edge 2011 of the first plate 201 to be flanged, the structure and size of the second end portion 1032 can be specifically set according to the size of the gap 203 between the first plate 201 and the second plate 202, and are not limited by the size of the gap 203, which can meet the flanging requirement inside the small gap 203 and is especially suitable for the flanging of the edge 2011 of the corresponding area of the A-pillar, B-pillar and C-pillar of the automobile.
[0046] In some embodiments, the first driving mechanism 102 further includes a fixed portion 1021, and the driving portion 1022 is movably inserted into the fixed portion 1021. The driving portion 1022 has a first position and a second position and can be switched between the first position and the second position, the driving portion 1022 drives the second end portion 1032 to enter the gap 203 and push the edge 2011 to be flanged when switched from the first position to the second position, and the driving portion 1022 drives the second end portion 1032 to move out of the gap 203 when switched from the second position to the first position.
[0047] The position of the first end portion 1031 is changed by the driving portion 1022 relative to the fixed portion 1021, and the position change of the first end portion 1031 forms a lever pry on the second end portion 1032, so as to drive the second end portion 1032 to enter or move out of the above-mentioned gap 203, thereby completing the flanging and exiting the door structure 200. For example, the first driving mechanism 102 can be a gas cylinder, and the driving portion 1022 can be moved relative to the fixed portion 1021 under the action of gas pressure, so as to be switched between the first position and the second position.
[0048] In some specific embodiments, when the driving part 1022 is in the first position, the driving part 1022 is in a retracted state relative to the fixed part 1021, and when the driving part 1022 is in the second position, the driving part 1022 is in an extended state relative to the fixed part 1021. The driving part 1022 switches from the retracted state to the extended state, that is, switches from the first position to the second position.
[0049] like Fig. 1 The edging device 100 shown has a first drive mechanism 102 located on the left side of the support 101 and a door structure 200 located on the right side of the support 101. The drive part 1022 switches from a retracted state to an extended state, that is, the first end 1031 switches from a first position to a second position. During this process, the first end 1031 moves approximately upward. Using the lever action, the second end 1032 of the lever 103 moves approximately downward and enters the gap 203 between the first plate 201 and the second plate 202. As the first end 1031 continues to move, the second end 1032 pushes the edge 2011 continuously towards the first plate 201 in the gap 203. When the first end 1031 switches to the second position, the second end 1032 pushes the edge 2011 to a smaller angle, thereby completing the edging.
[0050] In other specific embodiments, when the driving part 1022 is in the first position, the driving part 1022 is in an extended state relative to the fixed part 1021, and when the driving part 1022 is in the second position, the driving part 1022 is in a retracted state relative to the fixed part 1021. The driving part 1022 can also drive the second end 1032 to complete the flanging when it switches from the extended state to the retracted state, that is, from the first position to the second position.
[0051] In some embodiments, the size of the insertion of the fixing part 1021 when the driving part 1022 is in the first position is greater than the size of the insertion of the fixing part 1021 when the driving part 1022 is in the second position. That is, when the driving part 1022 switches from the retracted state to the extended state, that is, from the first position to the second position, the fixing part 1021 and the support 101 can be located on the same side of the lever 103, which facilitates the overall layout of the edging device 100.
[0052] In some embodiments, the second end 1032 is bent, and the concave side of the second end 1032 is used to push the edge 2011 to be turned over. The bent structure is more conducive to the cooperation between the second end 1032 and the edge 2011, so that the second end 1032 and the edge 2011 have the largest contact area, which makes it easier for the second end 1032 to provide better pushing force to the edge 2011, thereby improving the turning efficiency and accuracy of the edge 2011.
[0053] In some embodiments, the first driving mechanism 102 further comprises a fixed part 1021, the driving part 1022 is movable relative to the fixed part 1021, and the fixed part 1021 is fixedly connected to the support 101. The edge covering device 100 further comprises a second driving mechanism 104, the second driving mechanism 104 has a driving end 1041, at least one of the fixed part 1021 and the support 101 is connected to the driving end 1041 and drives the lever 103 synchronously under the driving of the driving end 1041, and the lever 103 presses the edge 2011 along the line by using the second end part 1032.
[0054] The driving end 1041 of the second driving mechanism 104 can be connected to the fixed part 1021, can be connected to the support 101, or can be connected to the fixed part 1021 and the support 101. The first driving mechanism 102 and the support 101 are driven to move synchronously by the driving end 1041, so that the position of the second end part 1032 changes, and by setting the driving direction of the driving end 1041, the second end part 1032 can be made to produce directional movement, that is, the edge 2011 along the line is further moved towards the first plate 201, and then the edge 2011 along the line is pressed tightly, so that the edge covering is more reliable.
[0055] In some embodiments, the second end part 1032 is of a bent type, the inner concave side of the second end part 1032 is used to push the edge 2011 to be covered, and an end of the second end part 1032 is provided with a pressing block 1032a, which is used to press the edge 2011 along the line tightly.
[0056] The bent type structure is more conducive to the cooperation between the second end part 1032 and the edge 2011, can make the second end part 1032 and the edge 2011 have the maximum contact area, facilitate the second end part 1032 to provide a better pushing force to the edge 2011, and improve the covering efficiency and accuracy of the edge 2011. The pressing block 1032a is arranged at the end of the second end part 1032, that is, corresponds to the edge 2011 along the line, after the second end part 1032 pushes the edge 2011 to a very small angular position, the second driving mechanism 104 drives the first driving mechanism 102 and the support 101, so that the pressing block 1032a of the second end part 1032 moves a small distance towards the first plate 201, and the edge 2011 along the line is pressed tightly.
[0057] In some embodiments, the fixed part 1021 is connected to the driving end 1041, and the second driving mechanism 104 and the support 101 are arranged on the two sides of the first driving mechanism 102, so as to avoid the second driving mechanism 104 from the placement of the door structure 200, and make the overall edge covering device 100 more suitable for the layout of the door structure 200, so as to smoothly complete the edge covering.
[0058] In some embodiments, the lever 103 is rotatably connected to the support 101 through the rotary joint 105, the distance between the rotary joint 105 and the second end 1032 is much smaller than the distance between the rotary joint 105 and the first end 1031, so that the movement of the second end 1032 can be controlled with higher precision, the movement of the second end 1032 is more stable and reliable, and the flanging is more smoothly completed.
[0059] Another purpose of the embodiments of the present application is to provide a vehicle door structure 200, which comprises a first plate 201 and a second plate 202, the second plate 202 is arranged on the inner side of the first plate 201 and a gap 203 is formed between the first plate 201 and the second plate 202, the gap 203 is used for the second end 1032 of the lever 103 in the above-mentioned flanging device 100 to enter and push the edge 2011 of the first plate 201 to be flanged. In some embodiments, the edge 2011 is arranged corresponding to the position where at least one of the A-pillar, the B-pillar and the C-pillar of the vehicle door structure 200 is located.
[0060] The vehicle door structure 200 provided by the embodiments of the present application can use the flanging device 100 provided by the embodiments of the present application to flange the outer plate under the condition that the gap 203 between the outer plate and the inner plate is limited, so that the vehicle door structure 200 has a flanging structure inside the small gap 203, which can improve the assembly stability and the sealing performance between the vehicle door components, thereby improving the product quality. Especially, the edge 2011 of the area corresponding to the A-pillar, the B-pillar and the C-pillar of the vehicle door structure 200 is more difficult to be flanged because the gap 203 of the area corresponding to the A-pillar, the B-pillar and the C-pillar is smaller, the edge 2011 of the area corresponding to the A-pillar, the B-pillar and the C-pillar of the vehicle door structure 200 is flanged by using the flanging device 100 provided by the embodiments of the present application, so that the vehicle door structure 200 has a flanging structure inside the smaller gap 203, which can comprehensively improve the assembly stability and the sealing performance between the vehicle door components.
[0061] As shown in Fig. 2 and Fig. 3 The gap 203 between the outer plate and the inner plate of the area corresponding to the A-pillar, the B-pillar and the C-pillar of the vehicle door structure 200 can be as small as 30mm, the bending distance of the edge 2011 can be 5mm, and the length of the edge 2011 can be 20mm.
[0062] The above only describes the preferred embodiments of the present application and should not be used to limit the present application, any modifications, equivalent replacements and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
