Description

Technical Field

[0001] This invention relates to the field of automobile manufacturing technology, and in particular to support devices and power assist equipment. Background Technology

[0002] During the vehicle production process, before disassembling the car door, it is necessary to use a power-assisted device to clamp the car door. Specifically, the power-assisted device first drives the robotic arm gripper to move to the preset station, and then continues to drive the robotic arm gripper to fit against the door panel. The gripper clamps the car door to prevent it from being scratched. The robotic arm is then activated to clamp the gripper tightly, and the car door is further removed from the car body and placed on the car door conveyor tray.

[0003] In the mixed production process of vehicles, different door designs need to be disassembled on the same production line. Due to the rigid contact of the existing support device, the current power-assisted equipment often requires manual adjustment of the support device to adapt to the different door structures of different car models during the disassembly process of different doors.

[0004] When the production line encounters a change in vehicle model, operators need to adjust the support angle of the existing support devices and assist equipment. This process affects production efficiency and increases labor costs. Summary of the Invention

[0005] The purpose of this invention is to provide a support device and an assistive device to improve the support adaptability for different shaped car doors, increase production efficiency and reduce labor costs.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Support device, including:

[0008] support;

[0009] A backrest, one end of which is rotatably connected to the bracket, and the backrest can abut against the door panel of the vehicle door;

[0010] An elastic element, one end of which is connected to the bracket and the other end of which is connected to the backing plate;

[0011] When the door panel presses against the backrest, the elastic element is compressed so that the backrest supports the door panel.

[0012] As an alternative support device, the bracket includes a first plate and a second plate connected to the first plate, with one end of the second plate away from the first plate hinged to the backing plate.

[0013] As an alternative support device, the second plate is provided with an adjustment component, which is used to abut against the backing plate to limit the maximum travel of the backing plate after being squeezed by the door panel.

[0014] As an alternative to the support device, the adjustment assembly includes an adjustment screw and a fixing plate. The fixing plate is fixed to the side wall of the second plate away from the backing plate. The adjustment screw is screwed to the fixing plate and passes through the second plate. The adjustment screw can abut against the backing plate.

[0015] As an alternative support device, the second plate is provided with a positioning hole, and one end of the elastic element is placed in the positioning hole and connected to the adjustment assembly.

[0016] As an optional support device, the support device further includes an adjusting block, which is fixed to the side wall of the backing plate near the bracket. The adjusting block is provided with a limiting groove, and the other end of the elastic element is inserted into the limiting groove and connected to the limiting groove.

[0017] As an alternative to the support device, the adjusting block is a wedge-shaped block, and the adjusting block is inclined relative to the surface of the bracket away from the surface of the bracket.

[0018] As an optional support device, the backrest is U-shaped, with two straight arms supporting the door panel. A connecting block is provided on the horizontal arm connecting the two straight arms. The connecting block and the backrest are integrally formed, and the backrest is hinged to the bracket through the connecting block.

[0019] As an alternative to the support device, a reinforcing rib is provided between the first plate and the second plate.

[0020] The assist device includes a drive component, a gripper driven by the drive component, and a support device as described in any of the above embodiments. The bottom of the door panel is placed on the gripper, and the drive component can drive the gripper to approach the backing plate to clamp the door panel.

[0021] Beneficial effects:

[0022] In the first aspect of the invention, the elastic element allows the backing plate to have a certain range of motion relative to the support, giving the backing plate a certain degree of flexibility in its supporting function. This allows the device to adaptably support door panels of different shapes. When the production line changes its production tasks and a different door panel shape is required, the pressing backing plate will rotate at a certain angle to adaptably support the door panel due to the different door panel shapes. The flexible supporting function of this device can continuously adapt to a variety of different door panels within an adjustable range, avoiding the need for operators to manually adjust the support structure when the production line changes its production tasks. This effectively improves production efficiency and reduces labor costs.

[0023] In a second aspect of the invention, an assistive device equipped with this apparatus can effectively adapt to various door panel shapes and improve the production efficiency of the entire production line. Attached Figure Description

[0041] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0042] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0043] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0044] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0045] Please see the appendix Figure 1 - Appendix Figure 4 The first aspect of this embodiment relates to a support device (hereinafter referred to as the "device"), which includes a bracket 1, a backing plate 2, and an elastic member 3. One end of the backing plate 2 is rotatably connected to the bracket 1, and the backing plate 2 can abut against the door panel 110 of the vehicle door 100. One end of the elastic member 3 is connected to the bracket 1, and the other end is connected to the backing plate 2. When the door panel 110 presses against the backing plate 2, the elastic member 3 is compressed to allow the backing plate 2 to support the door panel 110.

[0046] In this embodiment, the bracket 1 can be fixed to the support base of the power assist device via a detachable connection, specifically using screw or plug-in connections, to facilitate installation, disassembly, and maintenance. The bracket 1 is entirely made of metal and can be either a split structure or an integral structure. The backing plate 2 is hinged to the bracket 1 for rotational connection. The backing plate 2 is in direct contact with the door panel 110, and the door panel 110 abuts against the side wall of the backing plate 2. The backing plate 2 supports the car door 100. Furthermore, during the disassembly of the car door 100, there is interaction between the backing plate 2 and the door panel 110 to ensure clamping stability. The bracket 1 and the backing plate 2 are connected by an elastic element 3. The elastic element 3 can be a standard metal spring. The elastic element 3 provides a certain force between the backing plate 2 and the bracket 1. The fixed travel distance allows the support of the backing plate 2 to have a certain degree of flexibility, enabling the device to adaptably support door panels 110 with different shapes. For example, when a door panel 110 of one shape is placed against the backing plate 2, the door panel 110 will press against the backing plate 2, causing the elastic element 3 to compress. The backing plate 2 rotates at a first preset angle to adaptably support the door panel 110. When the production line changes production tasks, due to the different shapes of the door panels 110, the pressing backing plate 2 will rotate to a second preset angle to adaptably support the door panel 110. The flexible support function of this device can continuously adapt to a variety of different door panels 110 within an adjustable range, avoiding the need for operators to manually adjust the support structure when the production line changes production tasks, effectively improving production efficiency and reducing labor costs.

[0047] Optionally, the bracket 1 includes a first plate 11 and a second plate 12 connected to the first plate 11, wherein the end of the second plate 12 away from the first plate 11 is hinged to the backing plate 2.

[0048] In this embodiment, both the first plate 11 and the second plate 12 are plate-shaped components, which are connected to form an L-shaped structure. The first plate 11 is placed horizontally and fixedly connected to the support seat of the assistive device, while the second plate 12 is placed vertically and rotatably connected to the backing plate 2.

[0049] Furthermore, a reinforcing rib 13 is provided between the first plate 11 and the second plate 12.

[0050] Because the second plate 12 is subjected to the squeezing action of the backing plate 2 and the elastic element 3, the stress at the connection between the first plate 11 and the second plate 12 is relatively concentrated, making the connection prone to damage during frequent stress. In this embodiment, a reinforcing rib plate 13 is connected between the first plate 11 and the second plate 12. The reinforcing rib plate 13 is a right-angled triangle to accommodate the relative positional relationship between the first plate 11 and the second plate 12. The two right-angled sides of the reinforcing rib plate 13 are welded to the first plate 11 and the second plate 12 respectively to increase the connection strength. In this embodiment, one reinforcing rib plate 13 is provided. In other embodiments, the number of reinforcing rib plates 13 can be adjusted to consider both connection strength and economic efficiency.

[0051] Please see the appendix Figure 4 and attached Figure 5 Optionally, the backrest 2 is U-shaped, and the two straight arms of the backrest 2 are used to support the door panel 110. The horizontal arm used to connect the two straight arms is provided with a connecting block 21. The connecting block 21 and the backrest 2 are an integral structure. The backrest 2 is hinged to the bracket 1 through the connecting block 21.

[0052] Please continue to refer to the appendix. Figure 7 In this embodiment, the two straight arms of the back plate 2 can abut against the door panel 110 to support the door panel 110. The two straight arms are symmetrically arranged plate-shaped parts. The connecting block 21 of the back plate 2 is an integral structure with the back plate 2 to facilitate installation and improve the compactness of the entire device. Of course, in other embodiments, the connecting block 21 can also be welded to the back plate 2. Further, the connecting block 21 is provided with a connecting hole 211. A boss 122 is provided on the side wall of the second plate 12 away from the first plate 11. A rotating shaft 123 passes through the boss 122. Correspondingly, the rotating shaft 123 is inserted into the connecting hole 211, so that the boss 122 and the connecting block 21 form a hinge structure. In this embodiment, after the hinge engagement is completed between the connecting block 21, the rotating shaft 123 and the boss 122, the rotating shaft 123 can also be directly welded to the boss 122 to avoid the use of the axial limiting part of the rotating shaft 123 and improve the compactness of the entire hinge structure.

[0053] Please see the appendix Figure 4 - Appendix Figure 6 Optionally, a protective plate 22 is attached to the back panel 2 near the door panel 110. The protective plate 22 and the back panel 2 can be connected by adhesive or screw. The protective plate 22 is made of polyurethane material. During the process of the protective plate 22 and the door panel 110 pressing against each other, the polyurethane material can protect the door panel 110 and prevent the door panel 110 from being damaged.

[0054] Please see the appendix Figure 4 Optionally, the second plate 12 is provided with an adjustment component, which is used to abut against the back plate 2 to limit the maximum stroke of the back plate 2 after being squeezed by the door plate 110.

[0055] In this embodiment, the adjustment component can adjust the relative position of the backrest 2 to adaptively change the maximum stroke of the backrest 2 after being pressed by the door panel 110. The adjustment component can adopt various structures; for example, it can be a telescopic rod, a slide rail, or even a linear motor or hydraulic cylinder. Those skilled in the art can make a reasonable selection based on economy and space layout.

[0056] Please see the appendix Figure 4 and attached Figure 7 - Appendix Figure 9Furthermore, the adjustment assembly includes an adjustment screw 41 and a fixing plate 42. The fixing plate 42 is fixed to the side wall of the second plate 12 away from the backing plate 2. The adjustment screw 41 is screwed to the fixing plate 42 and passes through the second plate 12. The adjustment screw 41 can abut against the backing plate 2.

[0057] In this embodiment, since the overall device does not occupy much space, and in order to ensure that the adjustment method of the whole device is simple and economical, the adjustment component adopts the method of adjusting screw 41 and fixing plate 42 to adjust the maximum stroke of the back plate 2 after being squeezed by door plate 110.

[0058] Specifically, the fixing plate 42 is a quadrilateral plate. Near the four apex corners of the fixing plate 42, it is screwed to the side wall of the second plate 12 away from the backing plate 2 by screws. The adjusting screw 41 and the fixing plate 42 are provided with internal threads for cooperating with the adjusting screw 41. By rotating the adjusting screw 41, the adjusting screw 41 is adjusted to face or move away from the backing plate 2, thereby adjusting the gap between the adjusting screw 41 and the backing plate 2. When the door panel 110 presses against the backing plate 2, the backing plate 2 rotates and can continuously move closer to the adjusting screw 41. When it presses against the adjusting screw 41, it means that the backing plate 2 has reached the preset maximum stroke. Of course, the operator can further increase or decrease the gap between the adjusting screw 41 and the backing plate 2 by rotating the adjusting screw 41 to set the maximum stroke to be within a certain range.

[0059] Optionally, the second plate 12 is provided with a positioning hole 121, and one end of the elastic element 3 is placed in the positioning hole 121 and connected to the adjustment assembly.

[0060] In this embodiment, the positioning hole 121 is opened opposite the fixing plate 42, and the fixing plate 42 covers one side of the positioning hole 121. The adjusting screw 41 passing through the fixing plate 42 passes through the positioning hole 121. The elastic element 3 is sleeved on the adjusting screw 41, with one end placed in the positioning hole 121. The diameter of the positioning hole 121 is slightly larger than the diameter of the elastic element 3, which is used to limit the elastic element 3. At the same time, the elastic element 3 can be connected to the fixing plate 42 by welding.

[0061] Please see the appendix Figure 4 and attached Figure 10 Furthermore, the support device also includes an adjustment block 5, which is fixed to the side wall of the backing plate 2 near the bracket 1. The adjustment block 5 is provided with a limiting groove 51, and the other end of the elastic member 3 is inserted into the limiting groove 51 and connected to the limiting groove 51.

[0062] In this embodiment, a circular limiting groove 51 is provided on the adjusting block 5. The other end of the elastic member 3 is inserted into the limiting groove 51 and connected to the bottom wall of the limiting groove 51. Of course, the two can be connected by welding. The limiting groove 51 is used to limit the other end of the elastic member 3. The diameter of the limiting groove 51 is larger than the diameter of the elastic member 3.

[0063] Furthermore, the adjusting block 5 is a wedge-shaped block, and the adjusting block 5 is inclined relative to the surface of the support 1 away from the surface of the support 1.

[0064] In this embodiment, one side surface of the adjusting block 5 is attached to the bracket 1 and fixed to the bracket 1 by screws. The other side surface (wedge-shaped surface) of the adjusting block 5 is inclined relative to the surface attached to the bracket 1, so that the adjusting block 5 is wedge-shaped as a whole. When the device is in use, the backing plate 2 will rotate at a certain angle, and the elastic element 3 will be compressed. By processing the adjusting block 5 into a wedge-shaped block, the extension direction of the limiting groove 51 is perpendicular to the wedge-shaped surface. In the initial state of rotation, the elastic element 3 can remain straight in the axial direction. The elastic element 3 has no force component in other directions, which facilitates the assembly of the entire device.

[0065] The second aspect of this embodiment also relates to an assistive device, which includes a drive member 200 and a gripper 210 drivenly connected to the drive member 200, and the bottom of the door panel 110 is placed on the gripper 210. The drive member 200 can drive the gripper 210 to approach the backing plate 2 to clamp the door panel 110.

[0066] In this embodiment, the driving component 200 can be a cylinder, which is connected to the gripper 210 for driving the gripper 210 to move and bring the gripper 210 close to the backing plate 2 to hold the door panel 110.

[0067] The auxiliary equipment equipped with this device can effectively adapt to various door panel shapes 110, improving the production efficiency of the entire production line.

[0068] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
