[0066] In recent years, CTC (Cell to Chassis) has emerged as one of the latest research directions in electric vehicle power batteries. CTC eschews the concept of a battery pack and integrates the battery cells directly into the chassis. The application of CTC technology effectively reduces weight, eliminates intermediate processes and components, and the space saved by fewer components allows for more batteries to be installed, thereby increasing range. This technology is also seen as a key direction for future electric vehicles, and many automakers have proposed CTC technology routes.

[0067] During vehicle assembly, transport tools are required to carry components to the chassis, especially above the chassis for assembly. However, the support arms of general transport tools are too large and too long, occupying a large amount of space under the components. As a result, the chassis cannot be directly connected to the components during the assembly process, affecting the loading efficiency.

[0068] Based on the above considerations, in order to solve the problem that the chassis cannot be directly connected with the components during the assembly of the components and the chassis in the CTC technology, thereby affecting the loading efficiency, the present application provides a transport tooling, including a carrier and multiple pairs of support assemblies, the carrier having a moving mating part that cooperates with the running track; the support assembly includes a connecting member and a supporting member, the supporting member is connected to the carrier through the connecting member, the two supporting members in each pair of support assemblies are spaced apart laterally and are respectively installed on the side of the two connecting members facing each other, and the supporting member is provided with a supporting surface for supporting the components to be transported.

[0069] In a transport tooling of this structure, multiple pairs of support assemblies are provided, and the support members of each pair of support assemblies support the components to be transported at both ends in the horizontal direction, and reduce the encroachment on the bottom space of the components, thereby meeting the needs of assembling the components with other components below, such as the needs of assembling the upper body and the chassis, reducing the working hours of the assembling operation, and improving the loading quality and efficiency.

[0070] In this application, the component to be transported is an upper vehicle body.

[0071] Unless otherwise specified, the front-to-back direction in this application is the longitudinal direction of the vehicle, that is, the X direction; the left-right direction is the lateral direction of the vehicle, that is, the Y direction; and the up-down direction is the vertical direction of the vehicle, that is, the Z direction.

[0072] According to some embodiments of the present application, as shown in FIG. 1 to FIG. 6 , the present application provides a transport tool 4 , which includes a carrier 41 and multiple pairs of support assemblies 42 .

[0073] The carrier 41 has a motion engagement portion 411 that engages with the running track 3 .

[0074] In this embodiment, the running track 3 extends along the assembly line and is used to transport workpieces between various workstations. The carrier 41 can bear the weight of the component 1. The carrier 41 is connected to the running track 3 via a kinematic engagement portion 411, allowing the carrier 41 to move along the running track 3, thereby transporting the component 1 to be transported. The carrier 41 can have a frame-like structure to enhance its structural strength. The kinematic engagement portion 411 is located in the middle of the carrier 41, and multiple pairs of support assemblies 42 are provided around the periphery of the carrier 41 to ensure balanced force on the carrier 41.

[0075] The support components 42 are arranged in pairs, and there are multiple pairs. The support components 42 include connecting members 421 and support members 422. The support members 422 are connected to the carrier 41 through the connecting members 421. The two support members 422 in each pair of support components 42 are arranged at intervals along the horizontal direction, and the two support members 422 in each pair of support components 42 are respectively installed on the side of the two connecting members 421 facing each other. The support members 422 are provided with a support surface 42213 for supporting the component 1 to be transported.

[0076] Support member 422 is provided with a support surface 42213 for supporting component 1 to be transported. Support surface 42213 can abut against the bottom surface of component 1 to be transported to bear the weight of component 1. Support member 422 is connected to carrier 41 via connector 421. Connector 421 extends vertically, with the upper end of connector 421 connected to carrier 41 and the lower end of connector 421 connected to support member 422. The length of connector 421 is greater than the height of component 1 to be transported, so that component 1 to be transported is located between support member 422 and carrier 41. Connector 421 can transfer the bearing force of support member 422 to carrier 41.

[0077] In this embodiment, the two support members 422 of each pair of support assemblies 42 are arranged to be spaced apart in the transverse direction to support the two transverse ends of the component 1 to be transported, and the two support members 422 of each pair of support assemblies 42 are respectively installed on the side of the corresponding two connecting members 421 facing each other, so that the two connecting members 421 are located on both sides of the transverse direction of the component 1 to be transported to avoid the component 1 to be transported.

[0078] The plurality of pairs of support assemblies 42 are spaced apart in the longitudinal direction so that the plurality of pairs of support assemblies 42 can support the component 1 to be carried at multiple positions in the longitudinal direction, thereby improving the stability of the support.

[0079] According to the embodiment of the present application, multiple pairs of support assemblies 42 are provided, and the support members 422 of each pair of support assemblies 42 support the components 1 to be transported at both ends in the horizontal direction, and reduce the encroachment on the bottom space of the components 1, thereby meeting the requirements for assembling the components 1 with other components below, such as the requirements for assembling the upper body and the chassis 2, reducing the working hours of the assembling operation, and improving the loading quality and efficiency.

[0080] As shown in Figures 1 and 2, in some embodiments, the connecting member 421 can be set as a straight rod, or the middle section of the connecting member 421 can also be set as a curved rod. The middle section of the connecting rod 43 is bent to avoid component 1 or other tooling to avoid interference.

[0081] As shown in Figures 2 and 3, according to some embodiments of the present application, the transport tool 4 may further include a positioning member 423, which is mounted on the support member 422. When the support member 422 abuts against the component 1 to be transported, the positioning member 423 can be positioned and matched with the component 1 to be transported, positioning and fixing the component 1, thereby improving the installation accuracy of the component 1 and other components below, such as the installation accuracy of the upper body and the chassis 2.

[0082] According to the positioning member 423 of the embodiment of the present application, the component 1 to be transported is positioned by the positioning member 423, thereby improving the accuracy of assembly.

[0083] As shown in FIG. 3-FIG . 5 , according to some embodiments of the present application, the positioning member 423 may be provided on the support surface 42213 .

[0084] In this embodiment, a mating portion is provided on the side where the component 1 to be transported contacts the support surface 42213, and the positioning member 423 can be positioned and matched with the mating portion. When the support surface 42213 abuts and supports the component 1 to be transported, the positioning member 423 can be connected with the mating portion, and the connection is simple.

[0085] The mating portion may be the positioning groove 11. As shown in FIG5 , the positioning member 423 may be a positioning pin. The positioning groove 11 is configured as a slot, and the positioning pin can be inserted into the positioning groove 11 to achieve a positioning fit. Alternatively, the positioning member 423 may be a positioning bump. The positioning bump is configured in a form-fitting manner with the positioning groove 11, and the positioning bump can form-fit with the positioning groove 11 to achieve a positioning fit.

[0086] According to the embodiment of the present application, the positioning member 423 is set on the support surface 42213. When the support surface 42213 is connected to the component 1 to be transported, the positioning member 423 can cooperate with the positioning groove 11 on the component 1 for positioning, which makes positioning simple.

[0087] As shown in FIG. 3 , according to some embodiments of the present application, the positioning member 423 may be provided in an area of ​​the support surface 42213 facing away from the connecting member 421 .

[0088] It can be understood that the support surface 42213 is arranged on the side away from the connecting member 421 and close to the component 1 to be transported. By arranging the positioning member 423 in the area of ​​the support surface 42213 away from the connecting member 421, it is convenient for the positioning member 423 to be positioned and matched with the component 1, and the distance between the component 1 and the connecting member 421 will not be too close, thereby avoiding interference between the connecting member 421 and the component 1, and reducing the contact area between the support surface 42213 and the component 1, thereby reducing the encroachment of the support member 422 on the bottom space of the component 1 to be transported.

[0089] According to the embodiment of the present application, the positioning member 423 is arranged in the area of ​​the support surface 42213 away from the connecting member 421, which facilitates the positioning and cooperation of the positioning member 423 and the component 1, and reduces the encroachment of the support member 422 on the bottom space of the component 1 to be transported, thereby facilitating the assembly of the component 1 with other components below, such as the assembly of the upper body and the chassis 2.

[0090] As shown in FIG. 3 to FIG. 6 , according to some embodiments of the present application, the width of the end of the support surface 42213 away from the connector 421 may be smaller than the width of other areas.

[0091] It can be understood that the width direction of the support surface 42213 is the longitudinal direction of the component 1, and the end of the support surface 42213 away from the connecting member 421 is the part that mainly supports the component 1 to be transported. By setting the width of the end of the support surface 42213 away from the connecting member 421 to be smaller than the width of other areas, the contact area between the support surface 42213 and the component 1 to be transported is reduced, thereby reducing the encroachment of the support member 422 on the bottom space of the component 1 to be transported, and the larger width of other areas of the support surface 42213 can enhance the structural strength of the support member 422.

[0092] 5 and 6 , a clearance opening 21 is provided at the position of the chassis 2 corresponding to the support member 422. By reducing the contact area between the support surface 42213 and the upper vehicle body, the contact area between the chassis 2 and the upper vehicle body can be increased, thereby improving the strength of the connection structure between the chassis 2 and the upper vehicle body.

[0093] According to the embodiment of the present application, the contact area between the support surface 42213 and the component 1 to be transported is reduced to reduce the encroachment of the support member 422 on the bottom space of the component 1 to be transported, thereby facilitating installation and increasing the connection area between the component 1 and other components below, such as the connection area between the upper body and the chassis 2.

[0094] As shown in Figure 3, according to some embodiments of the present application, the positioning member 423 may include a first section 4231 and a second section 4232 connected along the axial direction of the positioning member 423, the first end of the first section 4231 is connected to the support member 422, the first end of the second section 4232 is connected to the second end of the first section 4231, and the cross-sectional area of ​​the first section 4231 may be greater than the cross-sectional area of ​​the second section 4232.

[0095] When the positioning groove 11 of the component 1 to be transported is deep, the height of the positioning member 423 needs to be set higher, which places certain requirements on the strength of the positioning member 423. In this embodiment, the positioning member 423 can be arranged in a columnar shape. The first end of the first section 4231 of the positioning member 423 is connected to the support member 422, the second end of the first section 4231 is connected to the first end of the second section 4232, and the second end of the second section 4232 is used to penetrate into the positioning groove 11 to perform a positioning function. In other words, the second section 4232 is mainly used for actual positioning. The second section 4232 is connected to the support member 422 through the first section 4231. By setting the cross-sectional area of ​​the first section 4231 to be larger than the cross-sectional area of ​​the second section 4232, that is, the diameter of the first section 4231 is larger than the diameter of the second section 4232, the structural strength of the entire positioning member 423 is strengthened, thereby reducing the probability of the positioning member 4233 breaking.

[0096] According to the embodiment of the present application, the positioning member 423 includes a first section 4231 and a second section 4232 , thereby improving the structural strength of the positioning member 423 .

[0097] As shown in FIG. 3 , according to some embodiments of the present application, the second end of the second segment 4232 may have a tapered surface.

[0098] In this embodiment, the peripheral edge of the second end of the second section 4232 can be chamfered to form a conical surface. When the second end of the second section 4232 cooperates with the positioning groove 11 of the component 1 to be transported, the second end of the second section 4232 can be more easily inserted into the positioning groove 11, which can reduce the interference caused by processing tolerances and improve the stability of positioning cooperation.

[0099] According to an embodiment of the present application, a tapered surface is provided at the second end of the second section 4232 , so that the second section 4232 can be positioned in cooperation with the positioning groove 11 of the component 1 to be transported, thereby reducing interference caused by machining tolerances.

[0100] As shown in FIG2 and FIG3 , according to some embodiments of the present application, the support member 422 may include a bracket 4222 and a support frame 4221. The bracket 4222 is mounted on the connector 421, the support frame 4221 is mounted on the bracket 4222, and the support surface 42213 is formed on the support frame 4221.

[0101] In this embodiment, bracket 4222 is mounted on connector 421, and support frame 4221 is mounted on bracket 4222, thereby achieving connection with connector 421. Support frame 4221 is used to support component 1 to be transported. By independently providing bracket 4222 and support frame 4221, workpiece production design is facilitated and the structural strength of individual components is improved.

[0102] Among them, the support frame 4221 and the bracket 4222 can be detachably connected, so that the support frame 4221 can be replaced and maintained in time after being damaged or worn, and support frames 4221 of different sizes can be installed to adapt to various vehicle models.

[0103] According to the support member 422 of the embodiment of the present application, the bracket 4222 and the support frame 4221 are separately arranged, which improves the stability of the connection and facilitates the maintenance and replacement of the support frame 4221. Replacing different support frames 4221 can also adapt to more car models.

[0104] As shown in Figures 2 and 3, according to some embodiments of the present application, the support frame 4221 may include a first mounting plate 42211 and a support plate 42212, the first mounting plate 42211 can be installed on the bracket 4222, the support plate 42212 can be installed on the first mounting plate 42211, and the upper surface of the support plate 42212 forms a support surface 42213.

[0105] In this embodiment, the first mounting plate 42211 can extend vertically to increase the connection area between the first mounting plate 42211 and the bracket 4222, and to increase the connection structural strength between the support frame 4221 and the bracket 4222. The support plate 42212 is installed on the side of the first mounting plate 42211 facing away from the bracket 4222 and extends horizontally to support the component 1 to be transported.

[0106] As shown in FIG. 2 and FIG. 3 , according to some embodiments of the present application, the support frame 4221 may further include a reinforcing rib 42214 , and the reinforcing rib 42214 may be connected between the first mounting plate 42211 and the support plate 42212 .

[0107] In this embodiment, the two ends of the reinforcing rib 42214 can be connected to the side of the first mounting plate 42211 facing away from the bracket 4222 and the upper surface of the support plate 42212, respectively, to enhance the structural strength of the support frame 4221, increase the bearing capacity of the support plate 42212, and improve the overall stability. Specifically, multiple reinforcing ribs 42214 can be provided, and the multiple reinforcing ribs 42214 can be spaced apart in the longitudinal direction to further enhance the structural strength.

[0108] According to the reinforcing ribs 42214 of the embodiment of the present application, the reinforcing ribs 42214 are provided to enhance the structural strength of the support frame 4221 , so as to better support the component 1 to be transported and enhance stability and safety.

[0109] As shown in FIG. 2 and FIG. 3 , according to some embodiments of the present application, the bracket 4222 may include a plurality of connecting plates 42221 and a second mounting plate 42222 .

[0110] Multiple connecting plates 42221 are arranged in parallel and spaced apart.

The second mounting plate 42222 is connected to the connecting plates 42221, and the support frame 4221 is installed on the second mounting plate 42222.

[0111] In this embodiment, the second mounting plate 42222 extends vertically and is disposed on the side of the connector 421 facing the component 1 to be transported. A plurality of connecting plates 42221 extend horizontally and are disposed on the side of the second mounting plate 42222 facing the connector 421. The connector 421 vertically penetrates through the plurality of connecting plates 42221 in sequence and is connected to the plurality of connecting plates 42221. The provision of the plurality of connecting plates 42221 enhances the structural strength of the second mounting plate 42222 and the connector 421 and effectively strengthens resistance to lateral torsional forces.

[0112] The first mounting plate 42211 and the second mounting plate 42222 can be detachably connected by a bolt assembly 4223. The connection structure is simple and has sufficient strength. The connecting plate 42221 and the connecting member 421 can be welded.

[0113] According to the bracket 4222 provided in the embodiment of the present application, a plurality of connecting plates 42221 are provided to enhance the connection strength between the bracket 4222 and the connecting member 421 , and a second mounting plate 42222 is provided to facilitate the installation of the support frame 4221 .

[0114] According to some embodiments of the present application, one end of the connecting member 421 facing away from the supporting member 422 is pivotally mounted on the supporting member 41 .

[0115] In this embodiment, the end of the connecting member 421 away from the supporting member 422, that is, the upper end of the connecting member 421, is pivotally mounted on the supporting member 41. Specifically, the upper end of the connecting member 421 is pivotally mounted on the supporting member 41 around the longitudinal axis.

[0116] In actual implementation, before transporting the component 1 to be transported, the two connecting members 421 of each pair of connecting components are driven to rotate relative to the carrying member 41 to drive the supporting members 422 to move away from each other in the horizontal direction to leave entry space for the component 1 to be transported. After the component 1 to be transported enters the transport station, the two connecting members 421 of each pair of connecting components are rotated to drive the supporting members 422 to retract in the direction of approaching each other, so that the supporting members 422 move to the bottom of the component 1 to be transported to play a supporting and positioning role.

[0117] According to the embodiment of the present application, the component 1 is avoided and supported by rotating the connecting member 421 to open outward and retract inward.

[0118] As shown in FIG. 1 and FIG. 2 , according to some embodiments of the present application, the support assemblies 42 located on the same side of the plurality of pairs of support assemblies 42 are connected by a connecting rod 43 .

[0119] In this embodiment, the connecting rod 43 extends longitudinally, and the connecting members 421 of the support assemblies 42 located on the same side in the horizontal direction in multiple pairs of support assemblies 42 are connected through the connecting rod 43, so that when the connecting rod 43 rotates, the multiple connecting members 421 located on the same side in the horizontal direction of the support member 41 rotate synchronously. The transmission structure is simple and cost-effective, and can enhance the overall structural strength and improve the bearing capacity.

[0120] According to the embodiment of the present application, a connecting rod 43 is provided to drive multiple support assemblies 42 located on the same side to move synchronously, thereby saving costs and improving structural strength.

[0121] As shown in Figures 1 and 2, according to some embodiments of the present application, the carrying tool 4 may further include a stabilizing bar 44. One end of the stabilizing bar 44 is pivotally mounted to the carrier 41, and the other end is connected to the connecting rod 43. The stabilizing bar 44 is spaced apart from the connecting member 421 along the length direction of the connecting rod 43.

[0122] In this embodiment, the upper end of the stabilizing rod 44 is pivotally connected to the carrier 41 about a longitudinal axis, and the pivot axis of the stabilizing rod 44 is coaxial with the pivot axis of the connecting rod 43. The lower end of the stabilizing rod 44 is connected to the connecting rod 43. The stabilizing rod 44 is spaced apart from the connecting member 421 along the length of the connecting rod 43, which can help improve the stability and structural strength of the connection.

[0123] There may be multiple stabilizing rods 44 , and the specific number is not limited. In one example, there are two stabilizing rods 44 , one of which is located at one longitudinal end of the carrier 41 , and the other is located between two adjacent connecting members 421 .

[0124] According to the stabilizer bar 44 provided in the embodiment of the present application, the stabilizer bar 44 is provided to improve the stability of the multiple support assemblies 42 when they move synchronously, and to improve the overall strength of the structure.

[0125] As shown in FIG3 , according to some embodiments of the present application, the distance from one end of the support member 422 in the support assembly 42 away from the corresponding connecting member 421 to the corresponding connecting member 421 may be L, satisfying: 150 mm ≤ L ≤ 350 mm.

[0126] In this embodiment, the parameter L can be specifically set based on the skirt size of component 1 for different vehicle models. For example, the parameter L can be L = 150mm, L = 200mm, L = 250mm, L = 300mm, or L = 350mm. By limiting the distance from the end of the support member 422 in the support assembly 42 facing away from the corresponding connector 421 to the corresponding connector 421, the volume of the support member 422 is reduced, and the space occupied by the support member 422 at the bottom of the component 1 is reduced. This can meet the requirements for assembling component 1 with other components below, such as the assembly of the upper body and chassis 2, reduce the assembly work time, and improve the quality and efficiency of loading.

[0127] According to some embodiments of the present application, as shown in FIG. 1 to FIG. 3 , the present application provides a transport tool 4 for transporting a component 1 , and the transport tool 4 includes a carrier 41 and a plurality of pairs of support assemblies 42 .

Second mounting plate 42222 is located on the side of connecting member 421 facing component 1 and is connected to multiple connecting plates 42221. First mounting plate 42211 and second mounting plate 42222 are detachably connected via multiple bolt assemblies 4223. The support plate 42212 is connected to the side of the first mounting plate 42211 facing away from the connector 421 and extends laterally. The width of the end of the support plate 42212 facing away from the connector 421 is smaller than the width of the rest of the support plate 42212. A support surface 42213 is formed on the upper surface of the support plate 42212.
