Therefore, the use of lightweight materials is an effective way to reduce the weight of the entire vehicle, improve energy efficiency and driving range. Although the car body panels are required to be lightweight, their strength and safety cannot be sacrificed at the same time.

DETAILED DESCRIPTION

[0026] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0027] The following describes the electric vehicle compartment panel bending device according to an embodiment of the present application in conjunction with the accompanying drawings.

[0028] like Figure 1-Figure 5 As shown, the electric vehicle compartment plate bending device of the embodiment of the present application may include a device frame (not shown in the figure), a bending mechanism 20, two roller assemblies 30 and an intermittent moving mechanism (not shown in the figure).

[0029] The device frame includes a first frame 11, a second frame 12 and a third frame 13, wherein the second frame 12 is arranged on the inner side of the first frame 11, the third frame 13 is arranged on a lateral side of the first frame 11, and a second telescopic component 131 is provided at the bottom of the third frame 13.

[0030] The bending mechanism 20 is disposed on the first frame 11 and the second frame 12. The bending mechanism 20 may include an upper mold 21 and a lower mold 22 that match each other, wherein the upper mold 21 is disposed on the first frame 11 through a first telescopic component 23, the lower mold 22 is disposed on the second frame 12, and a first top plate 24 is disposed in the lower mold 22.

[0031] It should be noted that the bottom of the first top plate 24 described in this embodiment can be installed in the lower mold 22 through a rebounder, an elastic spring, etc., so as to realize the function of ejecting the formed sheet 90 from the lower mold 22. The set first top plate 24 is a prior art and will not be described in detail here.

[0032] It should be noted that the first telescopic component 23 and the second telescopic component 131 described in this embodiment can be hydraulic cylinders, telescopic motors, etc. After the first telescopic component 23 is activated, it can drive the upper mold 21 connected thereto to move vertically, thereby realizing the extrusion bending and forming operation of the bending mechanism 20 on the plate 90. After the second telescopic component 131 is activated, it can drive the third frame 13 to move vertically, so that the third frame 13 can move correspondingly with the vertical movement of the plate 90, which is helpful for the stable intermittent movement operation of the plate 90.

[0033] The two roller assemblies 30 are symmetrically arranged up and down. Each roller assembly 30 is arranged longitudinally and may include a first roller 31 and a second roller 32 , wherein the length of the first roller 31 is greater than that of the second roller 32 .

[0034] The intermittent moving mechanism may include two moving components 40, and the two moving components 40 are longitudinally symmetrically arranged on both sides of the roller assembly 30. Each moving component 40 may include a support seat 41 and two moving parts 42 respectively arranged on both sides of the longitudinal direction of the support seat 41, wherein the support seat 41 is arranged on the third frame 13, and two moving holes 411 are symmetrically arranged on the upper and lower sides of the support seat 41. The roller assembly 30 is slidably arranged in the corresponding moving hole 411, and a linkage limit member is provided in the moving hole 411.

[0035] It should be noted that, in a moving component 40, a moving member 42 described in this embodiment is connected to two first rollers 31, and the other moving member 42 is connected to two second rollers 32. The operation of the two first rollers 31 and the operation of the two second rollers 32 do not interfere with each other, so that two groups of components can be formed to alternately drive the plate 90 to move, which helps to stabilize the plate 90 and further promotes the optimization and improvement of the bending efficiency of the plate 90.

[0036] It should be noted that the inner walls of the two adjacent moving holes 411 described in this embodiment are both arranged in a straight line, and the two transverse ends of the straight inner wall of the moving hole 411 are respectively set as the starting point and the end point. When the two first rollers 31 (or the two second rollers 32) move from the starting point to the end point of the corresponding moving hole 411, the linkage limiter described in this embodiment can limit the rotation of the two first rollers 31 (or the two second rollers 32), so that they can stably clamp the plate 90 in the middle, thereby achieving stable movement of the plate 90, which is conducive to the continuity of the bending operation of the plate 90.

[0037] Each moving member 42 may include a connecting seat 421 and two limit plates 422 rotatably disposed on the upper and lower sides of the connecting seat 421, wherein the connecting seat 421 is connected to the linear drive component 70, and the linear drive component 70 is disposed on the third frame 13. The two limit plates 422 are respectively disposed at both ends of the connecting seat 421 through the rotating member 50, and each limit plate 422 is provided with a through hole 4221, and the two ends of the first rotating roller 31 are respectively movable through the corresponding moving hole 411 and the through hole 4221, and the two ends of the second rotating roller 32 are respectively movable through the corresponding through hole 4221 and the moving hole 411.

[0038] It should be noted that the linear drive component 70 described in this embodiment can be a hydraulic cylinder, a slide module, etc. The linear drive component 70 is arranged in a one-to-one correspondence with the connecting seat 421, and the linear drive component 70 can drive the connecting seat 421 connected thereto to perform lateral reciprocating movement.

[0039] It should be noted that the rotating member 50 described in this embodiment can control the two limit plates 422 connected thereto to rotate, and the two limit plates 422 rotate in opposite directions. When the limit plate 422 connected to the first roller 31 rotates, the limit plate 422 can drive the first roller 31 thereon to rotate together, so that the first roller 31 can smoothly reset and move from the end point to the starting point.

[0040] When the limiting plate 422 connected to the second roller 32 rotates, the limiting plate 422 can drive the second roller 32 thereon to rotate together, so that the second roller 32 can smoothly return to the starting point from the end point.

[0041] As a possible scenario, refer to Figure 3 , relevant personnel can adjust the height of the movable hole 411 according to the actual depth of the bending part of the plate 90, so that when the two first rollers 31 (or the two second rollers 32) are resetting and moving from the end point to the starting point, the lower first roller 31 (or the second roller 32) can provide support for the bottom surface of the bending part of the plate 90, thereby facilitating stable intermittent movement of the plate 90.

[0042] Specifically, when the sheet 90 needs to be bent and formed, the relevant personnel first pass the head end of the sheet 90 horizontally through the upper mold 21 and the lower mold 22, and between the upper and lower roller assemblies 30 in turn, so that the two first rollers 31 (or the two second rollers 32) are respectively attached to the upper and lower surfaces of the sheet 90. At this time, the two first rollers 31 (or the two second rollers 32) and the corresponding moving parts 42 are in an active connection state.

[0043] After the plate 90 is placed, the relevant personnel start the first telescopic component 23. The first telescopic component 23 drives the upper mold 21 to move vertically downward to apply pressure to the plate 90. The plate 90 is gradually formed in the lower mold 22. During the process, the first top plate 24 is against the bottom surface of the plate 90, and the two sides of the plate 90 are retracted toward the bending part respectively. When the plate 90 retracts, it can drive the two first rollers 31 (or the two second rollers 32) to rotate.

[0044] After the first bending of the sheet 90 is completed, the relevant personnel drive the upper mold 21 to move vertically upward and reset through the first telescopic component 23. During the process, the first top plate 24 gradually moves upward and resets, and ejects the bent part of the sheet 90 from the lower mold 22. At the same time, the relevant personnel control the third frame 13 to move upward through the second telescopic component 131, and make the upward moving height of the third frame 13 equal to the ejection height of the sheet 90. At this time, the third frame 13 can drive the intermittent moving mechanism to move upward synchronously, so that the positional relationship between the sheet 90 and the intermittent moving mechanism remains unchanged.

[0045] Then, the relevant personnel can control the movable member 42 to move linearly laterally to the side away from the bending mechanism 20 through the corresponding linear drive component 70. At this time, the movable member 42 can drive the two first rollers 31 (or the two second rollers 32) thereon that are in contact with the plate 90 to move, and the two first rollers 31 (or the two second rollers 32) move from the starting point to the end point in the corresponding moving holes 411. During the process, the relevant personnel limit the rotation of the two first rollers 31 (or the two second rollers 32) through the linkage limiter, so that the two first rollers 31 (or the two second rollers 32) can stably clamp the middle plate 90, thereby realizing a one-time movement operation of the plate 90.

[0046] During a movement of the plate 90, relevant personnel control the movable member 42 to move linearly horizontally toward the side close to the bending mechanism 20 through the corresponding linear drive component 70. At this time, the movable member 42 can drive the two second rollers 32 (or two first rollers 31) thereon to move to the corresponding starting position, so that after the two first rollers 31 move the plate 90 once, the two second rollers 32 can replace the two first rollers 31 to contact the plate 90 again, so that the two second rollers 32 and the two first rollers 31 can alternately contact and move the plate 90, thereby realizing stable intermittent movement of the plate 90.

[0047] Then, the relevant personnel can use the first telescopic component 23 to drive the upper mold 21 to move vertically downward to perform a second bending on the plate 90. During the process, the relevant personnel can use the second telescopic component 131 to control the height of the third frame 13 and the plate 90 to be consistent, so that the above operation can be repeated to achieve continuous bending of the plate 90.

[0048] In one embodiment of the present application, Figure 2 and Figure 3 As shown, both longitudinally symmetrical side surfaces of the support seat 41 are provided with slide grooves 412, and one side of the connecting seat 421 is provided with a slider 4211, wherein the slider 4211 is slidably disposed in an adjacent slide groove 412, and the slider 4211 is connected to the output end of the corresponding linear drive component 70.

[0049] It is understandable that the linear driving component 70 can drive the connecting seat 421 to move laterally through the slider 4211 , and the sliding groove 412 is helpful to stabilize the movement of the slider 4211 .

[0050] Furthermore, if Figure 4 and Figure 5 As shown, a mounting cavity is provided in the connection seat 421, and a rotating member 50 is provided in the mounting cavity. The rotating member 50 may include two meshing gears 51 and a longitudinal rod 52, wherein the two gears 51 are respectively connected to the rotating shafts on the two limit plates 422. One end of the longitudinal rod 52 is threadedly embedded in the end surface of one of the gears 51, and the other end is movably passed through the mounting cavity and the slider 4211 in sequence and provided with a stopper 53, which is placed in the corresponding slide groove 412 and slidably contacts with the convex plate 80 in the slide groove 412, and a third telescopic component 81 is provided on the convex plate 80.

[0051] It should be noted that the third telescopic component 81 described in this embodiment can be a gas rod, a telescopic motor, etc. After the third telescopic component 81 is started, it can drive the convex plate 80 connected thereto to move longitudinally linearly. When the convex plate 80 moves, it can move the abutment 53 that abuts against it, so that the abutment 53 drives the longitudinal rod 52 to move. During the movement of the longitudinal rod 52, it can drive the gear 51 connected thereto to rotate. The rotation of the gear 51 can drive the gear 51 meshing therewith to rotate synchronously, and the two meshing gears 51 rotate in opposite directions, so that the two gears 51 respectively drive the limit plate 422 connected thereto to rotate, and then the limit plate 422 drives the first roller 31 (or the second roller 32) thereon to rotate together, so that the first roller 31 (or the second roller 32) moves on the inner wall of the corresponding moving hole 411.

[0052] Specifically, when the relevant personnel need to control the first roller 31 (or the second roller 32) to move from the corresponding end point to the starting point, the corresponding linear telescopic component and the third telescopic component 81 are started, so that during the lateral movement of the movable member 42, the two limit plates 422 drive the first roller 31 (or the second roller 32) thereon to rotate together, and when the first roller 31 (or the second roller 32) moves to the end point, the relevant personnel control the third telescopic component 81 to rotate and reset the limit plates 422.

[0053] Furthermore, if Figure 4 and Figure 5 As shown, a connecting groove 4111 connected to the slide groove 412 is provided on the straight portion of the movable hole 411, and the linkage limit member may include a second top plate 60, wherein the second top plate 60 is longitudinally movably arranged in the corresponding connecting groove 4111 through a spring 61, one end of the second top plate 60 is in sliding contact with the convex plate 80 in the slide groove 412, and the other end is laterally slidably provided with a rotating limit block 62, and a plurality of anti-slip strips 621 are provided on the side of the rotating limit block 62 adjacent to the bending mechanism 20.

[0054] It should be noted that the second top plate 60 described in this embodiment can move vertically during the movement of the convex plate 80 , so that the second top plate 60 drives the rotation limit block 62 thereon to move in and out of the corresponding connecting groove 4111 .

[0055] Specifically, when the two first rollers 31 (or the two second rollers 32) are required to drive the plate 90 therebetween to move linearly, the relevant personnel control the longitudinal movement of the convex plate 80 through the second telescopic component 131. During the process, the convex plate 80 drives the second top plate 60 connected thereto to move vertically, so that the rotation limit block 62 on the second top plate 60 emerges from the corresponding connecting groove 4111. At this time, the two first rollers 31 (or the two second rollers 32) can move to contact the corresponding rotation limit block 62, and can drive the corresponding rotation limit block 62 to move together. The anti-slip strip 621 set during the process can limit the first roller 31 (or the second roller 32) to prevent it from rotating, so that the two first rollers 31 (or the two second rollers 32) can stably clamp the plate 90 in the middle.

[0056] Furthermore, if Figure 4 and Figure 5 As shown, the adjacent ends of the second top plate 60 and the convex plate 80 that conflicts with it are both arranged in an arc shape. It can be understood that such a design makes the linkage between the second top plate 60 and the convex plate 80 that conflicts with it smoother.

[0057] Furthermore, if Figure 3 As shown, a plurality of anti-slip strips 621 are arranged on the arc-shaped side wall of the rotation limit block 62. It can be understood that the side of the rotation limit block 62 adjacent to the starting point is arranged in an arc shape, which can increase the contact area with the roller assembly 30, thereby being more conducive to limiting the corresponding roller assembly 30.

[0058] In summary, the electric vehicle compartment plate bending device of the embodiment of the present application, the intermittent movement mechanism and the roller assembly provided therein can realize intermittent movement of the plate, and can adapt to the indentation changes of the bending part of the plate during the process, thereby greatly improving the efficiency and continuity of the plate bending.
