For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] The embodiments of the present invention 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 only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] like Figure 1 and Figure 2 As shown in , this embodiment provides a multifunctional sub-assembly and assembly trolley, which includes a trolley base 1 and an operating table 2, and the trolley base 1 and the operating table 2 are connected by a lifting part 3;

[0037] The trolley base 1 includes a base 11, a wheel set 12 and an operating armrest 13. The operating armrest 13 is provided with a control element and an electric button 131. The control element controls the cylinder to control the extension and retraction of the lifting truss 31 in response to the lifting command. The electric button 131 is used to output the lifting command to the control element. A plurality of rolling universal balls 7 are provided between the operating table 2 and the tray 4. The connection between the operating table 2 and the tray 4 is provided with a first guide rail and a second guide rail, which are respectively used for the movement of the tray 4 in a first direction and a second direction, and the first direction is perpendicular to the second direction. The lifting part 3 includes two sets of lifting trusses 31 and a cylinder, and the cylinder can control the extension and retraction of the lifting trusses 31 in the vertical direction.

[0038] The multifunctional subassembly and assembly trolley also includes a tray 4 movably connected to the operating table 2, a plurality of positioning pins 5 and at least two support blocks 6. The upper surface of the tray 4 is provided with a plurality of mounting holes 41. The positioning pins 5 are detachably connected to a single mounting hole 41. The bottom of the support block 6 is provided with a protrusion 61 that can be detachably connected to at least two mounting holes 41.

[0039] Optionally, the locating pin 5 is threadedly connected or clamped with the mounting hole 41. The threaded connection between the locating pin 5 and the mounting hole 41 can ensure the connection strength, and the clamping connection between the locating pin 5 and the mounting hole 41 can ensure the convenience of installation. The setting can be adaptively performed according to actual working conditions.

[0040] For example, see Figure 3 As shown, the bottom surface of the support block 6 is provided with two protrusions 61, and the two protrusions 61 can be respectively engaged with the two mounting holes 41 on the tray 4. It can be understood that in this embodiment, the support block 6 is used to lift the workpiece, so the coverage area of ​​the support block 6 on the tray 4 is larger than the positioning pin 5. The support block 6 covers multiple mounting holes 41 on the upper surface of the tray 4, so the support block 6 needs to be connected to at least two mounting holes 41 to avoid movement. The support block 6 can also be configured to be connected to three or more mounting holes 41 to improve the connection strength and stability.

[0041] Specifically, the positioning pin 5 can rotate around the connection between the positioning pin 5 and the mounting hole 41. This arrangement can increase the operating space for the assembly operation at the part below the lifting piece by rotating the positioning pin 5 when the lifting piece is lifted by the supporting block 6, thereby further improving the convenience of the trolley. For example, see Figure 4 As shown, the plug-in part 52 and the outer part 51 of the locating pin 5 are configured as a separable structure, and a hinge 53 is provided at the connection between the plug-in part 52 and the outer part 51 to support the rotation of the locating pin 5. Of course, in other embodiments, the locating pin 5 can also be configured as a pull-out rotating locating pin, which will not be described in detail here.

[0042] In order to improve the convenience of switching between the trolley sub-packing and assembly function and the lifting function, the height of the support block 6 is greater than the height of the positioning pin 5. This arrangement can realize the switching between the trolley lifting function and the sub-packing and assembly function by a single action of taking and placing the support block 6. The height of the support block 6 can also be greater than or equal to the height after the positioning pin 5 is rotated to be parallel to the tray 4. After the positioning pin 5 is rotated to be parallel to the tray 4, the lifting function of the support block 6 can be directly performed, reducing the space occupied by the support block 6, and when switching between the trolley sub-packing and assembly function and the lifting function.

[0043] In the above embodiment, by means of the mounting holes 41 arranged on the upper surface of the tray 4, different types of parts to be assembled can be matched by adjusting the insertion position of the locating pin 5 or inserting different locating pins. By means of the rotatable design of the locating pin 5 and the height setting of the support block 6, it is possible to provide convenience for the support block 6 to lift workpieces such as new energy batteries by rotating the locating pin 5 without removing the locating pin 5. This enables the multifunctional subassembly and assembly trolley of the utility model to carry out subassembly or assembly of different types of vehicle frames and workpieces that need to be lifted and assembled, such as new energy batteries, through a single porous tray 4, thereby realizing the use of a same platform for multiple vehicle models and multiple components, and improving the versatility of the trolley.

[0044] In this embodiment, the mounting holes 41 are evenly spaced on the upper surface of the tray 4. The evenly spaced arrangement of the mounting holes 41 has better plannability and can quickly determine the positions of the mounting holes 41 of the workpiece corresponding to the positioning pins 5, thereby improving the efficiency of sub-assembly and assembly.

[0045] Specifically, the size and / or shape of each mounting hole 41 is different. It can be understood that different locating pins 5 have different functions. Some locating pins 5 need to bear most of the load of the parts to be assembled during the assembly process. Therefore, for different parts to be assembled, the size and / or shape of the locating pins 5 are different, and the size and / or shape of the mounting hole 41 needs to be adaptively configured according to the actual working conditions such as the model of the parts to be assembled.

[0046] In order to reduce the wear of the workpiece to be lifted, the support block 6 is a polyurethane support block, and the upper surface of the support block 6 is a plane. In practice, the workpiece to be lifted is mostly a workpiece with a flat bottom surface. The plane configuration of the upper surface of the tray 4 can adapt to most of the workpieces to be lifted, thereby improving the versatility of the trolley.

[0047] When the multifunctional sub-packaging and repackaging trolley of this embodiment realizes the sub-packaging and repackaging functions, the working process is as follows:

[0048] Step S01, determining the type of the positioning pin 5 and the corresponding mounting hole 41 according to the shape of the part to be assembled, installing the positioning pin and fixing the part to be assembled by the positioning pin;

[0049] Step S02, subassembling the workpieces to be installed on the parts to be assembled on the trolley to obtain the parts to be assembled;

[0050] Step S03, by operating the handrail 13, the trolley is moved to the lower part of the vehicle corresponding to the area to be assembled, and the electric button 131 is used to control the parts to be assembled to rise to the corresponding height;

[0051] Step S04, moving along the first guide rail and the second guide rail in the first direction and the second direction respectively until the to-be-assembled part is opposite to the to-be-assembled area, and assembling;

[0052] Step S05, the assembly is completed, the positioning pin 5 is disengaged, and the electric button 131 is operated to lower the tray 4 and move the trolley out.

[0053] When the multifunctional sub-assembling and combining trolley of this embodiment realizes the lifting function, the working process is as follows:

[0054] Step S11, rotating the positioning pin 5 to be parallel to the tray 4;

[0055] Step S12, installing the bracket 6;

[0056] Step S13, using the supporting block 6 to support the object to be supported;

[0057] Step S14, controlling the electric button 131 to raise the parts to be assembled to a corresponding height, and assembling the parts to be lifted;

[0058] Step S15, after the assembly is completed, the electric button 131 is operated to lower the tray 4 and move the trolley out.

[0059] The utility model can be used for the separate assembly of the front / rear subframes of fuel vehicles and new energy electric vehicles, and can also be used for the combined assembly of the front / rear subframes of fuel vehicles and new energy electric vehicles and the combined assembly of workpieces that need to be lifted and assembled, such as the power batteries of new energy electric vehicles. This effectively improves the versatility of the trolley and has the advantages of saving storage space, reducing equipment development costs, reducing the safety risks of pallet replacement, and optimizing production processes.

[0060] 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 methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here.
