The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terms used in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0045] Some embodiments of this application will be described in detail. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0046] See Figure 1 , this embodiment provides a turnover cart 100, which is used to carry and transport a vehicle body 400. In some embodiments, the vehicle body 400 is a white body 400 of a passenger car, and the welding and assembly operations of the white body 400 have been completed, but painting has not been carried out yet. For example, the turnover cart 100 can be used to transport the white body 400 off the production line of the welding shop to the laboratory and transport it to different positions in the laboratory.

[0047] See Figure 1 , the turnover cart 100 includes a frame 10, a movable rod 20, a first adjustment assembly 30, a second adjustment assembly 40, and a first positioning member 50. The frame 10 is used to carry the vehicle body 400, and the length direction of the frame 10 is parallel to the first direction X. The movable rod 20 is movably arranged on the vehicle body 400, and the length direction of the movable rod 20 is parallel to the second direction Y, and the second direction Y intersects the first direction X. The first adjustment assembly 30 is movably connected to the frame 10 and the movable rod 20, and the first adjustment assembly 30 is used to lock the movable rod 20 at different positions on the vehicle body 400 along the first direction X. The second adjustment assembly 40 is movably connected to the movable rod 20 along the second direction Y. The first positioning member 50 is connected to the second adjustment assembly 40, and the first positioning member 50 is used to position the vehicle body 400 on the frame 10.

[0048] The first adjustment assembly 30 can adjust the position of the movable rod 20 on the vehicle body 400 along the first direction X, and the second adjustment assembly 40 can adjust the position of the first positioning member 50 on the vehicle body 400 along the second direction Y. In this way, the adjustment of the installation position of the first positioning member 50 on the vehicle body 400 along the first direction X and the second direction Y is realized. Since the projections of the corresponding positioning structures on the vehicle body 400 on the frame 10 have different positions in the first direction X and the second direction Y, by adjusting the position of the first positioning member 50 relative to the vehicle body 400, the first positioning member 50 can position the white bodies 400 of different vehicle models, thereby improving the versatility of the turnover cart 100 and the applicable range of the turnover cart 100.

[0049] In some embodiments, see Figure 1, the number of the second adjusting components 40 is two. The two second adjusting components 40 are respectively movably connected to two ends of the movable rod 20 in the length direction. The number of the first positioning members 50 is two. The two first positioning members 50 are respectively connected to the two second adjusting components 40. The first positioning member 50 has a connected bearing surface 51 and a guiding surface 52. The bearing surface 51 is used for bearing the vehicle body 400, and the guiding surface 52 is connected to one end of the bearing surface 51 and is inclined upward relative to the bearing surface 51. Among them, the inclination direction of the guiding surface 52 is between the second direction Y and the third direction Z (the third direction Z intersects with the first direction X and the second direction Y. For example, the third direction Z can be set as the vertical direction, and the first direction X and the second direction Y are two directions intersecting in the horizontal plane), and is inclined upward away from the vehicle frame 10 in the third direction Z and inclined away from the vehicle frame 10 in the second direction Y. The two guiding surfaces 52 are used for positioning the vehicle body 400 in the second direction Y. In this way, the two guiding surfaces 52 can jointly limit the vehicle body 400 in the second direction Y, improving the placement reliability of the vehicle body 400. Moreover, when the vehicle body 400 is placed on the vehicle frame 10, the guiding surface 52 inclined relative to the bearing surface 51 can guide the vehicle body 400 to be horizontally placed on the vehicle frame 10.

[0050] In some embodiments, the skirt structure of the body-in-white 400 is arranged between the two first positioning members 50. By adjusting the distance between the two first positioning members 50 through the second adjusting component 40, the transfer cart 100 can be adapted to the body-in-white 400 with skirts of different widths.

[0051] In some embodiments, referring to Figure 2 , both ends of the movable rod 20 in the length direction respectively extend out of the vehicle frame 10, and the two second adjusting components 40 are respectively connected to the parts of the movable rod 20 extending out of the vehicle frame 10. In this way, the position adjustment of the second adjusting component 40 on the movable rod 20 can be facilitated. Of course, when the width of the vehicle body 400 is smaller than the width of the vehicle frame 10, the second adjusting component 40 can also be installed on the part of the movable rod 20 located inside the vehicle frame 10.

[0052] In some embodiments, referring to Figure 1 , the vehicle frame 10 includes two first longitudinal beams 11. The two first longitudinal beams 11 are spaced apart in the second direction Y, and the movable rod 20 is movably arranged between the two first longitudinal beams 11. The two first longitudinal beams 11 can stably support the movable rod 20, thereby improving the support stability for the vehicle body 400.

[0053] In some embodiments, referring to Figure 2, the movable rod 20 is arranged on the upper side of the first longitudinal beam 11 along the third direction Z. The first adjustment assembly 30 includes a first adjustment plate 31, a second adjustment plate 32 and a first fastener 33. The first adjustment plate 31 is arranged on the side of the movable rod 20 away from the first longitudinal beam 11. The second adjustment plate 32 is arranged on the side of the first longitudinal beam 11 away from the movable rod 20. The first fastener 33 connects the first adjustment plate 31 and the second adjustment plate 32, so that the first adjustment plate 31 and the second adjustment plate 32 clamp the movable rod 20 and the first longitudinal beam 11 to fix the movable rod 20 to the first longitudinal beam 11. By tightening the first fastener 33 to lock the first adjustment plate 31 and the second adjustment plate 32, the movable rod 20 can be fixed at a specified position along the first direction X of the first longitudinal beam 11, and further the position of the first positioning member 50 along the first direction X relative to the vehicle frame 10 can be fixed, ensuring the positioning reliability of the first positioning member 50. When it is necessary to adjust the position of the movable rod 20, loosen the first fastener 33 so that the gap size between the first adjustment plate 31 and the second adjustment plate 32 is greater than the height of the movable rod 20 and the first longitudinal beam 11 along the third direction Z, then the movable rod 20 and the first adjustment assembly 30 can be moved along the first direction X. After moving the movable rod 20 and the first adjustment assembly 30 to the next specified position, then tighten the first fastener 33 to lock the first adjustment plate 31 and the second adjustment plate 32, and the position adjustment of the first positioning member 50 along the first direction X can be completed. The first adjustment assembly 30 has low requirements for the matching structure of the movable rod 20 and the first longitudinal beam 11, and on the premise that the movable rod 20 is steplessly adjustable compared with the first longitudinal beam 11, the connection stability between the movable rod 20 and the first longitudinal beam 11 can be ensured to realize the reliable stepless adjustment of the first positioning member 50 along the first direction X, and it can be adapted to the positioning and installation of most body-in-whites 400.

[0054] In some embodiments, referring to Figure 3 , the first fastener 33 includes a first fastening rod 331, a first fastening head 332 and a first locking portion 333. The first adjustment plate 31 abuts against the movable rod 20, and the first fastening rod 331 passes through the first adjustment plate 31 and the second adjustment plate 32. The first fastening head 332 is connected to one end of the first fastening rod 331 extending out of the first adjustment plate 31 and abuts against the first adjustment plate 31. The first locking portion 333 is connected to one end of the first fastening rod 331 extending out of the second adjustment plate 32 and abuts against the second adjustment plate 32, so that the second adjustment plate 32 abuts against the first longitudinal beam 11. In this way, the first fastener 33 fixes the first adjustment plate 31, the second adjustment plate 32, the first longitudinal beam 11 and the movable rod 20. Among them, the first fastening rod 331 and the first fastening head 332 can be configured as screws, and the first locking portion 333 can be configured as a nut.

[0055] In some embodiments, referring to Figure 2There are four first fasteners 33 , two first fasteners 33 are respectively provided on both sides of the first longitudinal beam 11 along the second direction Y, and the two first fasteners 33 on both sides of the first longitudinal beam 11 are respectively distributed on both sides of the movable rod 20 along the first direction X. In this way, the reliability of the first adjustment component 30 fixing the movable rod 20 to the first longitudinal beam 11 can be improved.

[0056] In some embodiments, see Figure 1 The frame 10 further includes a first limiting crossbeam 15 and a second limiting crossbeam 16. The first limiting crossbeam 15 and the second limiting crossbeam 16 are spaced apart along the first direction X, one end of the first limiting crossbeam 15 is connected to the end of the first longitudinal beam 11, and one end of the second limiting crossbeam 16 is connected to the middle of the first longitudinal beam 11, and the first adjustment component 30 is movably arranged between the first limiting crossbeam 15 and the second limiting crossbeam 16 along the first direction X. In this way, the range of movement of the first adjustment component 30 along the first direction X can be limited, thereby limiting the adjustment range of the movable rod 20 along the first direction X. In other embodiments, the first adjustment component 30 can also be completely disassembled and installed on the part of the first longitudinal beam 11 at the second limiting crossbeam 16 away from the first limiting crossbeam 15.

[0057] In some embodiments, see Figure 4 , the second adjustment assembly 40 includes a third adjustment plate 41, a fourth adjustment plate 42 and a second fastener 43. The third adjustment plate 41 is located on one side of the movable rod 20 along the third direction Z, and the first positioning member 50 is connected to the third adjustment plate 41. The fourth adjustment plate 42 is located on the other side of the movable rod 20 along the third direction Z. The second fastener 43 connects the third adjustment plate 41 and the fourth adjustment plate 42 to fix the third adjustment plate 41 and the fourth adjustment plate 42 to the movable rod 20. By locking the third adjustment plate 41 and the fourth adjustment plate 42 by the second fastener 43, the first positioning member 50 can be fixed to the specified position of the movable rod 20 along the second direction Y, thereby fixing the position of the first positioning member 50 relative to the frame 10 along the second direction Y, thereby ensuring the positioning reliability of the second positioning member 60. When the position of the first positioning member 50 needs to be adjusted, the second fastener 43 is loosened to make the gap between the third adjustment plate 41 and the fourth adjustment plate 42 larger than the height of the movable rod 20 along the third direction Z, so that the second adjustment assembly 40 can be moved along the second direction Y. After the second adjustment assembly 40 reaches the next specified position, the second fastener 43 is locked to the third adjustment plate 41 and the fourth adjustment plate 42, so that the position adjustment of the first positioning member 50 along the second direction Y can be completed. In this way, the second adjustment assembly 40 can be adjusted relative to the movable rod 20 along the second direction Y steplessly, so as to realize reliable stepless adjustment of the first positioning member 50 along the second direction Y, and can adapt to the positioning and installation of most white bodies 400.

[0058] In some embodiments, seeFigure 4 The second fastener 43 includes a second fastening rod 431, a second fastening head 432, and a second locking portion 433. The third adjusting plate 41 and the fourth adjusting plate 42 respectively abut against both sides of the movable rod 20 along the third direction Z. The second fastening rod 431 passes through the third adjusting plate 41 and the fourth adjusting plate 42. The second fastening head 432 is connected to one end of the second fastening rod 431 extending out of the third adjusting plate 41 and abuts against the third adjusting plate 41. The second locking portion 433 is connected to one end of the second fastening rod 431 extending out of the fourth adjusting plate 42 and abuts against the fourth adjusting plate 42, so that the fourth adjusting plate 42 abuts against the movable rod 20. In this way, the second fastener 43 fixes the third adjusting plate 41, the fourth adjusting plate 42, and the movable rod 20. Wherein, the second fastening rod 431 and the second fastening head 432 can be configured as screws, and the second locking portion 433 can be configured as a nut.

[0059] In some embodiments, the number of the second fasteners 43 is four. Two second fasteners 43 are respectively arranged on both sides of the movable rod 20 along the first direction X, and the two second fasteners 43 on both sides of the movable rod 20 are distributed along the second direction Y. In this way, the reliability of the second adjusting assembly 40 fixed to the movable rod 20 can be improved.

[0060] In some embodiments, referring to Figure 4 the second adjusting assembly 40 further includes a fixing portion 44, and the fixing portion 44 is fixedly connected to the third adjusting plate 41 and the first positioning member 50. In this way, the connection reliability between the first positioning member 50 and the third adjusting plate 41 is improved. The fixing portion 44 can be configured as a fastening structure such as a screw, a pin, a buckle, etc. In other embodiments, the first positioning member 50 and the third adjusting plate 41 can also be connected by welding.

[0061] In some embodiments, referring to Figure 1 and Figure 5 the vehicle frame 10 further includes a mounting cross beam 17. The mounting cross beam 17 is connected to the first longitudinal beam 11. The mounting cross beam 17 is spaced from the movable rod 20 along the first direction X. The mounting cross beam 17 is provided with a plurality of mounting positions 181, and the mounting cross beam 17 extends along the second direction Y. The transfer vehicle 100 further includes a second positioning member 60. The second positioning member 60 is selectively connected to one of the mounting positions 181, and the second positioning member 60 is used to position the vehicle body 400 on the vehicle frame 10. In this way, by adjusting the second positioning member 60 at different mounting positions 181, the positioning requirements of different vehicle bodies 400 can be met.

[0062] In some embodiments, referring to Figure 6 a positioning hole 401401 is provided at the front end of the white vehicle body 400. The positioning hole 401401 cooperates with the second positioning member 60 to realize the positioning of the second positioning member 60 on the white vehicle body 400. The positioning hole 401401 is spaced from the skirt structure along the length direction of the vehicle body 400.

[0063] In some embodiments, referring to Figure 1 and Figure 5 , the vehicle frame 10 includes two mounting plates 18 which are spaced along the second direction Y on the mounting cross beam 17. A plurality of connection holes K2 are formed in each of the two mounting plates 18, and each connection hole K2 is configured as a mounting position 181. The second positioning member 60 is detachably fitted to any one of the plurality of connection holes K2. By the cooperation of the second positioning member 60 and the connection hole K2, the position replacement of the second positioning member 60 is convenient and fast, improving the use experience.

[0064] In other embodiments, the number of the mounting plates 18 and the number of the connection holes K2 can both be adjusted according to actual mounting requirements. In addition, the connection holes K2 can also be machined on the mounting plates 18 at any time according to the dimensions of a new vehicle model. Thus, the applicable range of the transfer vehicle 100 can still be guaranteed to the greatest extent.

[0065] In some embodiments, the connection hole K2 has an internal thread, and the second positioning member 60 includes a screw 61, a nut 62 and a positioning protrusion 63. The screw 61 is provided with an external thread, and one end of the screw 61 is in threaded connection with the connection hole K2. The nut 62 is sleeved on the screw 61. The positioning protrusion 63 is connected to the other end of the screw 61. By the threaded connection of the screw 61 and the connection hole K2, after the dimension of the screw 61 extending into the connection hole K2 changes, the screw 61 can still be reliably and fixedly connected to the mounting plate 18. Thus, the position of the positioning protrusion 63 along the third direction Z can also be adjusted according to the positioning requirements of the actual vehicle body 400, so as to not only ensure the cooperation between the second positioning member 60 and the positioning hole 401, but also avoid the second positioning member 60 bumping against the vehicle body 400 and ensure the integrity of the structure of the vehicle body 400. In addition, the nut 62 can limit the length dimension of the screw 61 extending into the connection hole K2 and enable the screw 61 to be fixedly connected to the connection hole K2 in the third direction Z, thereby avoiding the problem that the screw 61 displaces relative to the connection hole K2 when the transfer vehicle 100 carries the vehicle body 400 and improving the positioning reliability of the second positioning member 60.

[0066] In some embodiments, the cross-sectional dimension of the positioning protrusion 63 gradually decreases in the direction away from the mounting plate 18, and the outer peripheral surface of the positioning protrusion 63 is an arc conical surface.

[0067] In some embodiments, referring to Figure 1 and Figure 5, the mounting cross beam 17 includes a first beam body 171 and a second beam body 172. The first beam body 171 and the second beam body 172 are spaced apart along the first direction X, and both ends of the first beam body 171 in the length direction are connected to both ends of the second beam body 172 in the length direction. The mounting plate 18 is connected to both the first beam body 171 and the second beam body 172 at the same time. In this way, when the plate area of the mounting plate 18 is large, the mounting plate 18 can still be stably connected to the mounting cross beam 17. At the same time, the mounting plate 18 with a large plate surface can be provided with more connecting holes K2, further improving the application range of the turnover cart 100.

[0068] In some embodiments, please refer to again Figure 1 , the frame 10 further includes a plurality of second longitudinal beams 13. The plurality of second longitudinal beams 13 are spaced apart along the second direction Y. The length directions of the plurality of second longitudinal beams 13 all extend along the first direction X. Along the third direction Z, the plurality of second longitudinal beams 13 are located below the first longitudinal beam 11. One end of the length direction of the plurality of second longitudinal beams 13 is connected to the first limiting cross beam 15 and / or the second limiting cross beam 16, and the other end of the length direction of the plurality of second longitudinal beams 13 is connected to the mounting cross beam 17.

[0069] In some embodiments, refer to Figure 1 , the frame 10 further includes a third longitudinal beam 14. The third longitudinal beam 14 is connected between the side surface of the second limiting cross beam 16 and the side surface of the mounting cross beam 17. The length direction of the third longitudinal beam 14 is parallel to the first direction X. The turnover cart 100 further includes a positioning and adjusting assembly 83 and positioning wheels 81. The positioning and adjusting assembly 83 is movably connected to the third longitudinal beam 14 along the first direction X. The positioning wheels 81 are connected to the positioning and adjusting assembly 83. The specific structure of the positioning and adjusting assembly 83 can refer to the structure of the first positioning assembly 80, which will not be elaborated here.

[0070] In some embodiments, refer to Figure 1 , the turnover cart 100 further includes a plurality of wheels 192. The plurality of wheels 192 are connected to the frame 10.

[0071] In some embodiments, refer to Figure 1 , the number of the wheels 192 is four. The frame 10 further includes two fixed beams 191, and the two fixed beams 191 are respectively connected to the two first longitudinal beams 11. Two of the four wheels 192 are respectively connected to the two fixed beams 191. The other two of the four wheels 192 are respectively connected to both ends of the mounting cross beam 17 in the length direction. Among them, the two wheels 192 connected to the fixed beam 191 are universal wheels, so as to conveniently adjust the moving direction of the cart during the process of transporting the turnover cart 100.

[0072] In some embodiments, refer to Figure 7The vehicle frame 10 further includes a first connecting beam 121, a second connecting beam 122 and a third connecting beam 123. The first connecting beam 121 is connected to one end of a first longitudinal beam 11 away from the first limiting beam 15, the second connecting beam 122 is connected to one end of another first longitudinal beam 11 away from the first limiting beam 15, and the third connecting beam 123 is connected between the first connecting beam 121 and the second connecting beam 122. The length direction of the third connecting beam 123 is parallel to the second direction Y, and the third connecting beam 123 is spaced apart from the movable rod 20 along the first direction X. In this way, the length of the vehicle frame 10 along the first direction X can be appropriately extended, so as to facilitate stable support of the white body 400 with a longer length.

[0073] In some embodiments, see Figure 7 The frame 10 is provided with a mounting hole K1. The penetration direction of the mounting hole K1 intersects with the horizontal plane, for example, the penetration direction of the mounting hole K1 is parallel to the third direction Z. The turnover vehicle 100 further includes a handle 70, which includes a mounting portion 73 and a limiting portion 74. The mounting portion 73 is fitted in the mounting hole K1, and the limiting portion 74 is connected to the mounting portion 73 and abuts against the frame 10.

[0074] In this way, when the trolley 100 needs to be pushed, the handle 70 is installed in the mounting hole K1, so that the mounting portion 73 is pressed against the frame 10 under the gravity of the handle 70, so that the operator can push the trolley 100 through the handle 70 to move, thereby improving the convenience of operation. When the trolley 100 stops, the trolley 100 carrying the BIW 400 can be directly moved to the testing bench and other equipment, and the operator then removes the handle 70 from the mounting hole K1, thereby preventing the handle 70 from affecting the testing operation of the BIW 400. In this way, during the verification process of the BIW 400, it is not necessary to move the BIW 400 from the trolley 100 to the testing bench and other testing equipment, thereby reducing the turnover frequency of the BIW 400 in the laboratory, saving storage space in the laboratory, and improving the functionality of the trolley 100.

[0075] In some embodiments, see Figure 7 The frame 10 further includes a support portion 124 , the support portion 124 is connected to the third connection beam 123 , and the mounting hole K1 penetrates the support portion 124 along the third direction Z. When the handle 70 is mounted on the frame 10 , the limiting portion 74 abuts against the support portion 124 .

[0076] In some embodiments, see Figure 7 There are multiple mounting holes K1, and the multiple mounting holes K1 are distributed along the length direction of the third connecting beam 123. There are multiple mounting parts 73 and limiting parts 74, and the number of mounting parts 73, the number of limiting parts 74 and the number of mounting holes K1 are the same, so as to improve the stability of the handle 70 when it is installed on the frame 10.

[0077] In some embodiments, the number of mounting holes K1 is two. The number of mounting portions 73 and the number of limiting portions 74 are two. The handle 70 includes a first connecting rod 71 and two second connecting rods 72. The two second connecting rods 72 are respectively connected to both ends of the first connecting rod 71. One mounting portion 73 and one limiting portion 74 are provided at the other ends of the two second connecting rods 72. The shape of the second connecting rod 72 can be configured as a straight rod or a curved rod. In other embodiments, the number of the first connecting rods 71 can be set to be multiple, and the multiple first connecting rods 71 are spaced apart in the vertical direction, so as to improve the overall stability of the handle 70.

[0078] In this embodiment, full welding can be used for the connection methods of various parts such as the first longitudinal beam 11, the first connecting beam 121, the second connecting beam 122, the third connecting beam 123, the supporting portion 124, the second longitudinal beam 13, the third longitudinal beam 14, the first limiting cross beam 15, the second limiting cross beam 16, the first beam body 171, the second beam body 172, the mounting plate 18, the fixed beam 191 and the wheels 192. In some embodiments, the beam structure of the frame 10 can be made of square steel with a size of 5*5 cm and / or 5*7 cm, and the wall thickness of the square steel is 3 mm to ensure the load-bearing strength of the transfer cart 100.

[0079] See Figure 8 and Figure 9 In addition, this embodiment also provides a lifting assembly 300, which includes the aforementioned transfer cart 100 and a lifting device 200. The lifting device 200 is used to carry the frame 10 of the transfer cart 100 and drive the transfer cart 100 to move in the vertical direction.

[0080] According to the lifting assembly 300 of this embodiment, the transfer cart 100 can be transported onto the lifting device 200, and the lifting device 200 can drive the transfer cart 100 carrying the vehicle body 400 to move in the vertical direction. Using the transfer cart 100 as a load-bearing structure can simulate workstations at different heights for the vehicle body 400 assembly operation, without the need to transfer the vehicle body 400 from the transfer cart 100 to the lifting device 200 through a hoisting device, thereby reducing the turnover difficulty of the vehicle body 400 in the laboratory, expanding the application range of the transfer cart 100, and also saving the space for storing the transfer cart 100 in the laboratory. Among them, the lifting structure of the lifting device 200 can adopt existing lifting devices such as hydraulic cylinders, which will not be elaborated here.

[0081] In some embodiments, see Figures 10 to 13, the assembly assembly further includes a positioning component 80. The positioning component 80 includes a positioning wheel 81 and a positioning groove 82. The positioning groove 82 extends along the first direction X. One of the positioning wheel 81 and the positioning groove 82 is provided on the lifting device 200, and the other of the positioning wheel 81 and the positioning groove 82 is provided on the frame 10 of the transfer cart 100. The positioning wheel 81 can be fitted into the positioning groove 82 along the first direction X to position the transfer cart 100 on the lifting device 200.

[0082] In this way, the transfer cart 100 and the lifting device 200 can be positioned through the positioning component 80, improving the installation accuracy of the transfer cart 100 on the lifting device 200, that is, improving the positioning accuracy of the vehicle body 400 carried by the transfer cart 100 on the lifting device 200. Compared with the known method of positioning while hoisting the vehicle body 400 onto the lifting device 200 by a hoisting device, the positioning method between the vehicle body 400 and the lifting device 200 in this embodiment is simple, has high positioning accuracy, and reliable positioning effect.

[0083] In some embodiments, referring to Figures 10 to 13 , the positioning wheel 81 assembly further includes a positioning adjustment component 83. The positioning adjustment component 83 is connected to the third longitudinal beam 14 of the frame 10. The positioning wheel 81 is connected to the positioning adjustment component 83. The number of the positioning adjustment components 83 and the number of the positioning wheels 81 can both be set to multiple, and the multiple positioning wheels 81 are distributed along the first direction X to improve the positioning reliability.

[0084] In some embodiments, the positioning groove 82 has two groove surfaces oppositely arranged along the second direction Y, and the circumferential surfaces of the positioning wheel 81 are respectively tangent to the two groove surfaces to position the transfer cart 100 on the lifting device 200 in the second direction Y.

[0085] In some embodiments, referring to Figure 13 , the lifting device 200 includes a limit block 201 and two carrying platforms 202. The two carrying platforms 202 are spaced apart along the second direction Y, and the limit block 201 is connected between the two carrying platforms 202. The limit block 201 and the two carrying platforms 202 jointly enclose the positioning groove 82. The transfer cart 100 can move relative to the lifting device 200 until the positioning wheel 81 extends into the positioning groove 82 and finally abuts against the limit block 201, so as to realize the positioning and installation on the lifting device 200 in both the first direction X and the second direction Y. The transfer cart 100 can be stably placed on the lifting device 200 under the action of its gravity along the third direction Z, and then the accurate and reliable cooperation between the transfer cart 100 and the lifting device 200 is completed.

[0086] In some embodiments, referring to Figure 11The assembly also includes a locking component 90, which includes a first locking portion 333 and a second locking portion 433. One of the first locking portion 333 and the second locking portion 433 is connected to the turnover vehicle 100, and the other of the first locking portion 333 and the second locking portion 433 is connected to the lifting device 200. The second locking portion 433 has a locking hole 93, and the first locking portion 333 can be inserted into the locking hole 93 to be connected to the second locking portion 433.

[0087] In this way, during the simulated assembly process of the vehicle body 400 , the frame 10 and the lifting device 200 are kept fixedly connected via the locking assembly 90 , thereby reducing the possibility of relative displacement between the frame 10 and the lifting device 200 and improving the reliability of the simulated test.

[0088] In some embodiments, see Figure 14 , the second locking portion 433 is fixedly connected to the supporting platform 202 of the lifting device 200. The locking hole 93 penetrates the second locking portion 433 along the second direction Y. The locking assembly 90 further includes a locking seat 94. The locking seat 94 is connected to the frame 10, and the locking seat 94 is provided with a receiving hole 95, and the receiving hole 95 penetrates the locking seat 94 along the second direction Y. The first locking portion 333 can be movably engaged in the receiving hole 95 along the second direction Y. In this way, when the turnover vehicle 100 is separated from the lifting device 200, the first locking portion 333 can be accommodated in the receiving hole 95. After the turnover vehicle 100 is transported to the lifting device 200, the first locking portion 333 is pulled out from the receiving hole 95 and extends into the locking hole 93 of the second locking portion 433 to achieve locking.

[0089] In some embodiments, see Figure 14 The side wall of the locking seat 94 is provided with a guide slot 96, both ends of the guide slot 96 are closed, and the guide slot 96 penetrates along the lateral direction of the locking seat 94 to the communicating receiving hole 95. The first locking portion 333 includes a locking pin 911 and a shifting block 912. The locking pin 911 can be movably matched with the receiving hole 95. The shifting block 912 is connected to the side of the locking pin 911. The shifting block 912 extends from the guide slot 96 to the outside of the locking seat 94. The shifting block 912 can facilitate the operator to shift the locking pin 911 so that the locking pin 911 extends into or out of the locking hole 93. The cooperation between the shifting block 912 and the guide slot 96 can also ensure that the first locking portion 333 is stably accommodated in the locking seat 94, thereby preventing the first locking portion 333 from falling off when the turnover vehicle 100 is running alone.

[0090] In some embodiments, see Figure 14, the guide slide groove 96 includes a first section 961 and a second section 962. The first section 961 extends along the second direction Y, and the second section 962 is connected to the end of the first section 961 away from the second locking portion 433, and extends along the circumferential direction of the locking seat 94. In this way, when the turnover vehicle 100 works alone, the shift block 912 can be rotated into the second section 962 to ensure that the first locking portion 333 will not fall off relative to the locking seat 94. When the turnover vehicle 100 cooperates with the lifting device 200, the shift block 912 can be screwed into the first section 961 from the second section 962, and then moved along the second direction Y close to the second locking portion 433 until the locking pin 911 extends into the locking hole 93, completing the connection between the first locking portion 333 and the second locking portion 433.

[0091] In other embodiments, the first locking portion 333 and the locking seat 94 may be disposed on the supporting platform 202 , and the second locking portion 433 may be fixed to the vehicle frame 10 .

Although the present application has been described in detail with reference to the above preferred implementation modes, a person skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
