[0002] In the production and assembly process of buses and other vehicles, advanced technologies such as automation and intelligence are developing rapidly. The conveying device of the production line is an important equipment that carries the connection between various automated equipment and realizes the movement between various workstations in the bus production process. Therefore, requirements are put forward for the convenience and reliability of the connection and positioning of the vehicle frame on the conveying device. Especially in the bus industry, it has disadvantages such as large size, poor stability, inaccurate positioning, and transition connectors that have a great impact on subsequent processes. The displacement of the vehicle during assembly and inaccurate positioning on both sides will affect the subsequent processes.

[0003] Conventional technology uses welding to secure connectors to the vehicle frame, which is inconvenient and requires a welder. The height difference at the rear requires the connector to be raised, which reduces its strength and makes it susceptible to deformation. The center-to-center distance between the two brackets is difficult to maintain, requiring on-site welding. These brackets cannot be reused and must be cut off in the final assembly shop, damaging the electrophoretic coating and reducing the corrosion protection of the entire vehicle.

Another core aspect of this invention is a vehicle assembly production line incorporating this structure.

[0029] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0030] Please refer to Figures 1 to 8 , Figure 1 A schematic front view of a specific embodiment of the vehicle assembly transport support and positioning structure provided by the present invention; Figure 2 A side view schematic diagram of a specific embodiment of the vehicle assembly transport support and positioning structure provided by the present invention; Figure 3A schematic front view of a front support member in a specific embodiment of the vehicle assembly transport support and positioning structure provided by the present invention; Figure 4 A schematic side view of a front support member in a specific embodiment of the vehicle assembly transport support and positioning structure provided by the present invention; Figure 5 A schematic front view of a rear support member in a specific embodiment of the vehicle assembly transport support and positioning structure provided by the present invention; Figure 6 A schematic side view of a rear support member in a specific embodiment of the vehicle assembly transport support and positioning structure provided by the present invention; Figure 7 A structural schematic diagram of a front connecting member in a specific embodiment of the vehicle assembly transport support and positioning structure provided by the present invention; Figure 8 This is a structural schematic diagram of a rear connecting member in a specific implementation of the vehicle assembly transportation support and positioning structure provided by the present invention.

[0031] A specific embodiment of the present invention provides a vehicle assembly, transportation, and support positioning structure, comprising a chassis 1, a plurality of front supports 2, a plurality of rear supports 3, a plurality of front connectors 4, and a plurality of rear connectors 5. The conveying direction of the production line conveyor is longitudinal, and the direction across the conveying direction is transverse, i.e., the transverse and longitudinal directions are perpendicular to each other and both directions are horizontal. The chassis 1 extends longitudinally and connects to the production line conveyor. Driven by the conveyor, the chassis 1 moves longitudinally. The conveyor may be a plate chain or a skid. The plurality of front supports 2 are arranged in parallel transversely, and the plurality of rear supports 3 are arranged in parallel transversely. The front supports 2 and rear supports 3 are arranged in an array on the chassis 1. The plurality of front supports 2 are located in the front row, connected by a transverse line, and the plurality of rear supports 3 are located in the rear row, connected by a transverse line. Each row includes one front support 2 and one rear support 3. The front supports 2 and rear supports in the same row are arranged longitudinally, connected by a longitudinal line. Multiple rear supports 3 may also be arranged within a row.

[0032] The lower end of the front support member 2 is fixedly connected to the front end of the base frame 1, and the lower end of the rear support member 3 is fixedly connected to the rear end of the base frame 1. The upper ends of the front connecting member 4 and the rear connecting member 5 are detachably connected to the lower side of the frame 6 to be assembled, and each front connecting member 4 and each rear connecting member 5 are arranged corresponding to the position of each front support member 2 and each rear support member 3. A positioning hole 41 is provided at the lower end of the front connecting member 4, and a positioning pin 21 is provided at the upper end of the front support member 2. During assembly, the positioning pin 21 is inserted into the positioning hole 41, and the front support member 2 supports the front connecting member 4. A positioning groove 51 with a downward opening is provided at the lower end of the rear connecting member 5. The positioning groove 51 extends longitudinally. A positioning plate 31 is provided at the upper end of the rear support. During assembly, the positioning plate 31 extends into the positioning groove 51 and supports the bottom surface of the positioning groove 51.

[0033] During the working process, the front connecting member 4 and the rear connecting member 5 are installed under the frame 6, and the frame 6 is hoisted to the top of the base frame 1, so that the front connecting member 4 is aligned with the front support member 2, and the rear connecting member 5 is aligned with the rear support member 3, and the frame 6 is lowered, so that the positioning pin 21 is inserted into the positioning hole 41 to achieve positioning, so that the front support member 2 and the rear support member 3 jointly support the frame 6. Since the rear connecting member 5 adopts a positioning groove 51, after the positioning pin 21 is inserted into the positioning hole 41, the positioning plate 31 extends into the positioning groove 51, but the insertion position is not limited. The positioning plate 31 can move back and forth in the positioning groove 51, that is, the positioning groove 51 is only limited laterally and can move forward and backward longitudinally. Even if there is a longitudinal position error, the positioning plate 31 can be stably supported to improve applicability. After assembly is completed, the frame 6 is hoisted to separate the support and the connecting member, and the connecting member is disassembled at the same time.

[0034] The front pin and rear slot positioning form makes it easier to lock the frame into position after it is lifted. The enhanced contact surface makes the frame support more stable and meets various operation requirements. The connecting parts and the body are detachable. When the operation is completed, the connecting parts can be removed and recycled to avoid damaging the electrophoretic layer, saving production costs. The structure is simple and easy to produce. The sheet material structure and profile structure have low production costs.

[0035] Specifically, the front connecting member 4 includes a vertical front sleeve 42, and a transversely extending front ear plate 43 is provided at the upper end of the front sleeve 42. Front connecting holes 44 are provided at both ends of the front ear plate 43. The two front connecting holes 44 are respectively located on both sides of the front sleeve 42. When installed, the upper end surface of the front ear plate 43 is close to the lower side surface of the frame 6, and the frame 6 to be assembled is connected by bolts passing through the front connecting holes 44. A support plate 45 is provided at the lower end of the front sleeve 42, and a positioning hole 41 is provided in the middle of the support plate 45. The positioning pin 21 passes through the positioning hole 41 and extends into the front sleeve 42.

[0036] The rear connector 5 comprises a vertical rear sleeve 52, with a laterally extending rear lug 53 disposed at its upper end. Rear connection holes 54 are provided at each end of the rear lug 53, one located on either side of the rear sleeve 52. During installation, the upper end of the rear lug 53 abuts against the underside of the vehicle frame 6, and the rear lug 53 is connected to the vehicle frame 6 via bolts passing through the rear connection holes 54. A positioning slot 51 is provided at the lower end of the rear sleeve 52. The various components can be connected by welding, which simplifies the structure and facilitates fabrication. Alternatively, bolts can be used, or the structure of the connector can be adjusted.

[0037] Furthermore, the front connecting hole 44 and the rear connecting hole 54 are waist holes extending laterally, which can adjust the lateral position of the connecting member when the connecting member is connected to the frame 6 to avoid lateral position error.

[0038] In the vehicle assembly and transportation support and positioning structure provided by the specific embodiment of the present invention, the upper end of the front support member 2 is mounted with a front base 22, which is provided with a vertical positioning pin 21. At the same time, the lower end of the positioning pin 21 is provided with a limiting step. The front base 22 is mounted with a support platform 23, and the middle portion of the support platform 23 is provided with a through hole. During installation, the upper end of the positioning pin 21 passes through the support platform 23, so that the support platform 23 presses against the limiting step at the lower end of the positioning pin 21 and stably connects the support platform 23 to the front base 22. At the same time, after the positioning pin 21 is inserted into the positioning hole 41, the upper end surface of the support platform 23 abuts against the lower end surface of the support plate 45, increasing the contact area and improving support stability.

[0039] Preferably, the support platform 23 is connected to the front base 22 by countersunk bolts to ensure the flatness of the upper end surface of the support platform 23. A tightening bolt is provided on the side of the front base 22 to tighten the upper end of the front support member 2. Other connection methods can also be used, such as clip-on or threaded connection.

[0040] A rear base 32 is mounted on the upper end of the rear support member 3 , and a vertical positioning plate 31 is mounted in the middle of the rear base 32 . The two can be welded or threaded, both within the scope of protection of the present invention.

[0041] In order to adapt to different sizes of frames 6, the number of each support member can be adjusted, such as setting three or more support members in each row. In this specific embodiment, two front support members 2 and two rear support members 3 are symmetrically set, and a total of four support members support the four corners of the frame 6.

[0042] Based on the vehicle assembly and transportation support and positioning structures provided in the aforementioned embodiments, both the front support member 2 and the rear support member 3 are provided with height adjustment mechanisms to adjust their heights, ensuring that the vehicle frame 6 is level, thereby improving stability and usability. The front support member 2 and the rear support member 3 may utilize a jack or other type of height adjustment mechanism, all of which are within the scope of protection of the present invention.

[0043] In addition to the above-mentioned vehicle assembly and transportation support and positioning structure, a specific embodiment of the present invention also provides a vehicle assembly production line including the above-mentioned vehicle assembly and transportation support and positioning structure. The structures of other parts of the vehicle assembly production line can be referred to the prior art and will not be described in detail herein.
