[0042] like Figure 1 to Figure 2 As shown, Figure 1-2 The X direction shown in is the first direction, Figure 2The middle dotted line is a schematic diagram of the placement position of the part to be adjusted 3. The embodiment of the first aspect of the utility model provides a flush adjustment device, including a bracket 1 and a plurality of adsorption mechanisms 2, the bracket 1 having a limiting surface 11, the adsorption mechanism 2 is arranged on the bracket 1, and the plurality of adsorption mechanisms 2 are arranged along the circumference of the limiting surface 11, the plurality of adsorption mechanisms 2 are used to adsorb at least two parts to be adjusted 3, that is, one adsorption mechanism 2 can correspond to one part to be adjusted 3, or two or more adsorption mechanisms 2 can correspond to adsorb one part to be adjusted 3, but the plurality of adsorption mechanisms 2 need to adsorb at least two parts to be adjusted 3 respectively, so as to adjust the flush of two adjacent parts 3 to be adjusted to a preset value.

[0043] Among them, the adsorption mechanism 2 includes a suction cup 21 and an exhaust component 22. The suction cup 21 is used to adsorb the surface of the part to be adjusted 3. The exhaust component 22 is connected to the suction cup 21. The exhaust component 22 can suck the gas in the suction cup 21. The adsorption mechanism 2 is used to make the surface of the part to be adjusted 3 abut against the limiting surface 11 along the first direction.

[0044] With such a configuration, when in use, the flush adjustment device is placed at the connection position of two adjacent parts 3 to be adjusted, the suction cup 21 can be first attached to the surface of the part 3 to be adjusted, the exhaust assembly 22 is started, and the gas in the inner cavity of the suction cup 21 is discharged. The suction cup 21 is deformed under the action of the internal and external air pressure difference, and is firmly adsorbed on the surface of the part 3 to be adjusted. In the first direction, the size of the suction cup 21 is reduced when it is deformed, so as to drive the part 3 to be adjusted to shift, so that the surface of the part 3 to be adjusted abuts against the limiting surface 11, and the surfaces of multiple parts 3 to be adjusted abut against the limiting surface 11, and the range of movement is effectively limited, so that the flush of the surfaces of the two adjacent parts 3 to be adjusted is adjusted to the preset flush, for example, when the preset flush is zero, the surfaces of the two adjacent parts 3 to be adjusted are flush. Then the part 3 to be adjusted can be fixed again to maintain the preset flush between the adjacent parts 3 to be adjusted, so as to improve the flush assembly accuracy and assembly efficiency between the parts 3 to be adjusted.

[0045] This embodiment can be applied to the parts to be adjusted 3 made of various materials such as steel, aluminum, plastic, carbon fiber, etc., reducing the application limitations and solving the problem in the related art that the magnetic block is difficult to adjust the covering parts made of aluminum, plastic, carbon fiber, etc., other than steel, and has great application limitations.

[0046] In this embodiment, the limiting surface 11 can be, but is not limited to, a plane or a curved surface, and the limiting surface 11 can be set according to the shape of the surface of the part 3 to be adjusted. Moreover, the limiting surface 11 can include multiple partitions, each of which corresponds to the surface position of the part 3 to be adjusted one by one, and the multiple partitions can be flush with each other so as to adjust two adjacent parts 3 to be adjusted to the same height. Of course, there can also be a preset height difference between two adjacent partitions, and the surface of the part 3 to be adjusted is fixed after abutting against the corresponding partition, and the limiting surface 11 can adjust the surface of the adjacent parts 3 to be adjusted to the preset height difference. Among them, the first direction can be configured as a vertical direction, and the first direction can be selected according to the need for face difference operation adjustment. The connection between the adsorption mechanism 2 and the bracket 1 can be achieved by connecting the vacuum component 22 to the bracket 1, or it can also be achieved by connecting the suction cup 21 to the bracket 1.

[0047] like Figure 1 to Figure 2 As shown, in some embodiments, the suction cup 21 has a connecting end 211 and an adsorption end 212, the connecting end 211 is connected to the vacuum component 22, and in the first direction, the adsorption end 212 is protruding relative to the limiting surface 11, that is, the limiting surface 11 is retracted into the surface where the adsorption ends 212 of multiple suction cups 21 are located, and the distance between the adsorption end 212 and the part 3 to be adjusted is smaller than the distance between the limiting surface 11 and the part 3 to be adjusted. The adsorption end 212 contacts the part 3 to be adjusted before the limiting surface 11, so that the suction cup 21 can exhaust the deformation and initially adsorb the surface of the part 3 to be adjusted before making the part 3 to be adjusted fit and abut against the limiting surface 11, which can improve the adsorption force of the suction cup 21 on the part 3 to be adjusted and avoid detachment.

[0048] like Figure 1 to Figure 2 As shown, in some embodiments, the suction assembly 22 includes a cylinder 221, a piston 222 and a driving member 223. The cylinder 221 is connected to the bracket 1 so that the cylinder 221 can rely on the bracket 1 and the position of the cylinder 221 is stable. The cylinder 221 is connected to the suction cup 21, for example, the suction cup 21 can be fixed to the end of the cylinder 221, and the suction cup 21 can rely on the cylinder 221, and the position of the suction cup 21 is stable.

[0049] The piston member 222 is disposed in the cylinder 221 and is slidably and hermetically connected to the cylinder 221. The piston member 222 and the cylinder 221 are surrounded to form an air cavity, and the air cavity is connected to the inner cavity of the suction cup 21. The driving member 223 is transmission-connected to the piston member 222, and the driving member 223 is used to drive the piston member 222 to slide and adjust the air outlet or air intake of the air cavity, so that the suction cup 21 can intake or exhaust air accordingly.

[0050] With such a configuration, when in use, the driving member 223 can be activated to drive the piston member 222 to move forward in the first direction, compress the air cavity and discharge the gas in the air cavity. Then, the suction cup 21 can be attached to the surface of the part 3 to be adjusted, and the driving member 223 can be activated to drive the piston member 222 to move in the opposite direction in the first direction, so that negative pressure is formed in the air cavity, and the gas in the inner cavity of the suction cup 21 is sucked, so that the inner cavity of the suction cup 21 also forms negative pressure and deforms, firmly adsorbed on the surface of the part 3 to be adjusted, and the surface of the part 3 to be adjusted is abutted against the limit surface 11. When the position of the part 3 to be adjusted is fixed, the driving member 223 can be activated to drive the piston member 222 to move forward in the first direction, and the gas in the air cavity is discharged to the inner cavity of the suction cup 21. The air pressure in the inner cavity of the suction cup 21 is close to the external environment pressure, so that the suction cup 21 is separated from the part 3 to be adjusted.

[0051] In this embodiment, the driving member 223 may include but is not limited to a combination of a cylinder, a hydraulic cylinder or a motor and a lead screw nut. The driving member 223 may be selected according to usage requirements and can drive the piston member 222 to slide.

[0052] Among them, at least the part of the piston 222 that presses against the side wall of the cylinder 221 is elastic, which can keep the contact position between the piston 222 and the cylinder 221 sealed during the sliding process, improve the sealing of the air cavity, and further improve the adsorption strength of the suction cup 21 on the surface of the adjustable part 3.

[0053] like Figures 2 to 3 As shown, in some embodiments, the driving member 223 includes a pressing member 2231 and an elastic member 2232. The pressing member 2231 can be pressed manually by a user, or pressed by a pressing device. The pressing member 2231 is slidably connected to the cylinder 221. One end of the pressing member 2231 is connected to the piston member 222, and the other end extends to the outside of the cylinder 221. The pressing member 2231 is used to drive the piston member 222 to slide and adjust the air outlet of the air cavity. The pressing member 2231 can not only be pressed by an external force, but also guide the piston member 222 to slide. The elastic member 2232 can be, but is not limited to, a spring or an elastic cylinder. The elastic member 2232 is arranged between the piston member 222 and the inner wall of the cylinder 221. The elastic member 2232 is used to drive the piston member 222 to slide and adjust the air intake of the air cavity, that is, after the user's pressing force disappears, the elastic member 2232 can provide an elastic reset force for the piston member 222.

[0054] With such arrangement, when in use, the pressing member 2231 can drive the piston member 222 to move forward under the action of external force to adjust the air cavity to discharge gas, and the elastic member 2232 undergoes elastic deformation to store energy, and then the suction cup 21 can be attached to the surface of the part 3 to be adjusted. When the external force is removed, the elastic member 2232 recovers its deformation and pushes the piston member 222 to move in the opposite direction, and the air cavity absorbs the gas in the inner cavity of the suction cup 21, so that the suction cup 21 is firmly adsorbed on the surface of the part 3 to be adjusted, thereby adjusting the surface of the part 3 to be adjusted to abut against the limit surface 11.

[0055] like Figures 2 to 3 As shown, in some embodiments, the adsorption mechanism 2 also includes a pressure relief member 23, which is disposed on the suction cup 21. The pressure relief member 23 is used to connect the inner cavity of the suction cup 21 with the external environment. The pressure relief member 23 can be, but is not limited to, a pressure relief valve or a switch valve, which can be directly switched by the user to connect the suction cup 21 with the external environment for rapid pressure relief, and the operation is quick and efficient.

[0056] like Figures 2 to 3 As shown, in some embodiments, the bracket 1 includes a frame body 12 and a suction block 13, and the adsorption mechanism 2 is arranged on the frame body 12. The adsorption mechanism 2 is supported by the frame body 12 and is in a stable position. The limit surface 11 is arranged on the suction block 13, that is, the suction block 13 can be used as a surface difference adjustment standard for multiple parts 3 to be adjusted. The suction block 13 is detachably connected to the frame body 12, and the connection can be but not limited to clamping, bonding, magnetic connection or bolt connection, which can facilitate the maintenance and replacement of the suction block 13, so that the limit surface 11 maintains the adjustment accuracy, avoids the replacement of the bracket 1 as a whole, and reduces material waste. Moreover, a frame body 12 can be equipped with suction blocks 13 of various specifications, sizes or adjustment types, and the sizes of the limit surfaces 11 of multiple suction blocks 13 can be different. The limit surfaces 11 of different suction blocks 13 can also be designed as different partitions.

[0057] In some embodiments, at least the portion of the leveling block 13 that presses against the part 3 to be adjusted is flexible, that is, there is flexible contact between the leveling block 13 and the surface of the part 3 to be adjusted, thereby reducing the contact between the limiting surface 11 and the part 3 to be adjusted and damaging the surface of the part 3 to be adjusted.

[0058] The suction block 13 and the suction cup 21 may be made of elastic materials, such as rubber or silicone.

[0059] like Figures 2 to 3 As shown, in some embodiments, a plurality of connecting arms 14 are provided on the side of the frame body 12, the adsorption mechanism 2 is provided on the connecting arm 14, the suction cup 21 abuts against the surface of the connecting arm 14, and the surface of the connecting arm 14 can support and limit the connecting end 211 of the suction cup 21, thereby reducing the shaking movement of the connecting end 211 of the suction cup 21 along the first direction, so that the suction cup 21 can adsorb the adjustment part 3 more stably and reduce shaking.

[0060] The surface of the connecting arm 14 can be retracted into the limiting surface 11 to form a receiving groove, and the receiving groove is used to receive the suction cup 21 to provide a placement space for the suction cup 21 .

[0061] like Figures 2 to 3As shown, in some embodiments, two adsorption mechanisms 2 are provided, and the two adsorption mechanisms 2 are respectively arranged on both sides of the bracket 1, and the two adsorption mechanisms 2 are symmetrically arranged with respect to the bracket 1, so that the force arms of the adsorption mechanisms 2 on both sides of the bracket 1 to the adjustable part 3 can be symmetrical, which is convenient for users to hold and apply force.

[0062] like Figures 2 to 3 As shown, an embodiment of the second aspect of the utility model provides a vehicle assembly system for assembling a vehicle, comprising a flush adjustment device and a fastening mechanism in any of the above-mentioned schemes, a plurality of parts to be adjusted 3 are arranged on the vehicle, each part to be adjusted 3 is used to be adsorbed on the adsorption mechanism 2 respectively, and the surface of each part to be adjusted 3 is used to abut against the limiting surface 11, and the fastening mechanism is used to fasten the parts to be adjusted 3, and the flush adjustment device can be used to adjust the flush of the plurality of parts to be adjusted 3 to a preset flush, and can be applied to parts to be adjusted 3 made of various materials such as steel, aluminum, plastic, carbon fiber, etc., thereby reducing application limitations.

The vehicle cover may be, but not limited to, a door, a fender, or a side panel. The internal connection part may be, but not limited to, a vehicle frame.
