Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and more specifically to a transmission device. Background Technology

[0002] In the automotive manufacturing process, transfer devices transport the vehicle body structure to different processing stations. These devices typically include a roller bed and skids mounted on it. The skids carry the body structure and move along pre-set tracks on the roller bed, thus transferring the body structure to different processing stations. Currently, for the production of some small-batch models, or in overseas regions with lower levels of automation, manual skids are often required for transporting the body structure.

[0003] A prior art technology provides a body-in-white conveyor skid, including a frame mounted on a roller bed. Multiple brackets for fixing the body-in-white are mounted upwards on the frame. A sleeve is provided on the frame, into which a forklift plate is inserted. Magnets for attracting the forklift plate are provided on the side walls of the sleeve. A positioning groove is provided downwards on the frame. A telescopic rod for inserting into the positioning groove is provided on the roller bed. A distance sensor is provided at the front end of the frame. When the conveyor skid senses a distance reaching a set limit, it begins to brake. As it decelerates and approaches the welding station, the forklift plate next to the welding station quickly inserts into the sleeve. Simultaneously, the telescopic rod on the roller bed extends upwards. As the magnet on the sleeve attracts the forklift plate, the telescopic rod pushes into the positioning groove, thus accurately positioning the conveyor skid at the welding station.

[0004] Since the body-in-white transport skid needs to pass through multiple processing stations, in order to ensure that the body-in-white transport skid slides smoothly on the roller bed and avoid interference with the roller bed, the aforementioned body-in-white transport skid cannot be directly contacted and positioned through the fixed structure on the roller bed. This makes the positioning process of the aforementioned body transport skid complex and difficult to adapt to the needs of manual operation. Utility Model Content

[0005] The purpose of this invention is to provide a transmission device to solve the problem of how to make the positioning operation of the skid mechanism on the rolling bed simple and convenient.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This application provides a transmission device, including a roller bed mechanism, a first skid mechanism, a second skid mechanism, a first positioning member, and a second positioning member. The roller bed mechanism includes a roller bed body, a second limiting component, and a third limiting component. Along the length direction of the roller bed body, the roller bed body includes a first station, a second station, and a third station arranged sequentially. The second limiting component and the third limiting component are both disposed at the second station, and are arranged along the width direction of the roller bed body. The first skid mechanism and the second skid mechanism are both slidably connected to the roller bed body. The first skid mechanism is movable between the first and second workstations, and the second skid mechanism is movable between the second and third workstations. A first positioning member is connected to the first skid mechanism, and a second positioning member is connected to the second skid mechanism. Along the length direction of the roller bed body, the projection of the first positioning member is located outside the projection of the third limiting component, and the projection of the first positioning member coincides with at least a portion of the projection of the second limiting component. The projection of the second positioning member is located outside the projection of the second limiting component, and the projection of the second positioning member coincides with at least a portion of the projection of the third limiting component.

[0007] According to the above technical means, since both the second and third limiting components are located at the second station, they are arranged along the width direction of the roller bed body. The projection of the first positioning member is outside the projection of the third limiting component, and at least part of the projection of the first positioning member coincides with the projection of the second limiting component. Similarly, the projection of the second positioning member is outside the projection of the second limiting component, and at least part of the projection of the second positioning member coincides with the projection of the third limiting component. In this way, when the first skid mechanism slides to the second station, the first positioning member can avoid the third limiting component, preventing interference when the first skid mechanism slides to the second station. Similarly, interference when the second skid mechanism slides to the second station can be avoided, thus ensuring smooth sliding of both the first and second skid mechanisms. Furthermore, the first skid mechanism can be limited and held at the second station by the second limiting component, and the second skid mechanism can also be limited and held at the second station by the third limiting component. This makes the positioning process when the first and second skid mechanisms slide to the second station simple and convenient, suitable for manual operation.

[0008] In some embodiments, the third limiting component includes a first sub-component and a second sub-component, which are spaced apart along the width direction of the roller bed body, and the second limiting component is located between the first sub-component and the second sub-component; the second positioning member includes a first sub-positioning member and a second sub-positioning member, which are spaced apart along the width direction of the roller bed body, and along the length direction of the roller bed body, the projection of the first sub-positioning member coincides at least partially with the projection of the first sub-component, and the projection of the second sub-positioning member coincides at least partially with the projection of the second sub-component.

[0009] According to the aforementioned technical means, since the third limiting component includes a first sub-component and a second sub-component, which are spaced apart along the width direction of the roller bed body, and the second positioning component includes a first sub-positioning component and a second sub-positioning component, with at least a partial overlap between the projection of the first sub-positioning component and the projection of the second sub-positioning component and the projection of the second sub-positioning component. In this way, when the second skid mechanism is located at the second station, the first positioning component limits the movement through the first and second sub-components, ensuring that both ends of the second skid mechanism are limited along the width direction of the roller bed body. This results in a more uniform force distribution on the second skid mechanism after it is limited at the second station, further improving the stability of the second skid mechanism's positioning on the roller bed body.

[0010] In some embodiments, the first sub-component includes a first limiting member and a first locking member. The first limiting member is fixedly connected to the roller bed body, and the first locking member is located on the side of the first limiting member near the third station. The first locking member is movably connected to the roller bed body along the height direction of the roller bed body. The second sub-component includes a second limiting member and a second locking member. The second limiting member is fixedly connected to the roller bed body, and the second locking member is located on the side of the second limiting member near the third station. The second locking member is movably connected to the roller bed body along the height direction of the roller bed body. When the second skid mechanism is located at the second station, the first sub-positioning member is located between the first limiting member and the first locking member, and the second sub-positioning member is located between the second limiting member and the second locking member.

[0011] According to the above technical means, since the first sub-assembly includes a first limiting member and a first locking member, and the second sub-assembly includes a second limiting member and a second locking member, the first locking member is movably connected to the roller bed body along the height direction of the roller bed body, and the second locking member is movably connected to the roller bed body along the height direction of the roller bed body. In this way, when the second skid mechanism moves to the second station, the first sub-positioning member contacts the first limiting member, and the second sub-positioning member contacts the second limiting member, thus realizing the positioning of the second skid mechanism. Then, by moving the first locking member and the second locking member upwards towards the roller bed body, the first sub-positioning member is positioned between the first limiting member and the first locking member, and the second sub-positioning member is positioned between the second limiting member and the second locking member, thereby making the second skid mechanism stably maintained at the second station, further improving the convenience of positioning the first skid mechanism and the second skid mechanism.

[0012] In some embodiments, the second limiting component includes a third limiting member and a third locking member. The third limiting member is fixedly connected to the roller bed body, and the third locking member is located on the side of the third limiting member closer to the first station. The third locking member is movably connected to the roller bed body along the height direction of the roller bed body. When the first skid mechanism is located at the second station, the first positioning member is located between the third limiting member and the third locking member. The first limiting member, the third limiting member, and the second limiting member are arranged sequentially along the width direction of the roller bed body, and the first locking member, the third locking member, and the second locking member are arranged sequentially along the width direction of the roller bed body.

[0013] According to the aforementioned technical means, since the second limiting component includes a third limiting member and a third locking member, the first limiting member, the third limiting member, and the second limiting member are arranged sequentially along the width direction of the roller bed body, and the first locking member, the third locking member, and the second locking member are also arranged sequentially along the width direction of the roller bed body. This allows the second limiting component to be positioned between the first sub-component and the second sub-component, utilizing the space between the first and second sub-components, resulting in a more compact layout and a more rational structural design for the second and third limiting components.

[0014] In some embodiments, the rolling bed mechanism further includes a first limiting component and a fourth limiting component. The first limiting component is disposed at a first station, and at least a portion of the projection of the first positioning member coincides with the projection of the first limiting component along the length direction of the rolling bed. The fourth limiting component is disposed at a third station, and at least a portion of the projection of the second positioning member coincides with the projection of the fourth limiting component along the length direction of the rolling bed.

[0015] According to the above technical means, since the first limiting component is located at the first station and the fourth limiting component is located at the third station, and at least a portion of the projection of the first positioning member coincides with the projection of the first limiting component along the length direction of the rolling bed; and at least a portion of the projection of the second positioning member coincides with the projection of the fourth limiting component along the length direction of the rolling bed, the first skid mechanism can be limited by the first limiting component at the first station, and the second skid mechanism can be limited by the fourth limiting component at the third station. This allows the first skid mechanism to be accurately positioned and maintain a stable position at the first station, and the second skid mechanism to be accurately positioned and maintain a stable position at the third station. This adapts to multi-station processing on a production line, improving the applicability of the transmission device.

[0016] In some embodiments, along the length direction of the roller bed, the projection of the first limiting component is located within the projection of the gap between the first sub-component and the second sub-component; and / or, the fourth limiting component includes a third sub-component and a fourth sub-component, the third sub-component and the fourth sub-component being spaced apart along the width direction of the roller bed body, and along the length direction of the roller bed body, the projection of the first sub-positioning member at least partially coincides with the projection of the third sub-component, and the projection of the second sub-positioning member at least partially coincides with the projection of the fourth sub-component.

[0017] According to the above technical means, since the third sub-component and the fourth sub-component are spaced apart along the width direction of the roller bed body, and along the length direction of the roller bed body, the projection of the first sub-positioning member coincides with the projection of the third sub-component, and the projection of the second sub-positioning member coincides with the projection of the fourth sub-component, when the second skid mechanism is located at the third station, the first sub-positioning member is limited by the third sub-component, and the second sub-positioning member is limited by the fourth sub-component, thereby making the second skid mechanism stable when it is located at the third station, and further improving the stability of the second skid mechanism's positioning on the roller bed body.

[0018] In some embodiments, the first skid mechanism includes a skid body and a handle structure connected to the skid body, the skid body being slidably connected to the roller bed body.

[0019] According to the aforementioned technical means, since the first skid mechanism includes a skid body and a handle structure connected to the skid body, and the skid body is slidably connected to the roller bed body, the operator can slide the skid body along the length direction of the roller bed body by holding the handle structure, thereby enabling the first skid mechanism to move between the first and second workstations, improving the ease of operation of the transmission device.

[0020] In some embodiments, the handle structure includes a connector, a support, and a grip, wherein the connector is connected to the skid body, the support is connected to the upper end of the connector, and the grip is connected to the end of the support away from the connector.

[0021] According to the above technical means, since the handle structure includes a connector, a support and a grip, the connector is connected to the skid body, the support is connected to the upper end of the connector, and the grip is connected to the end of the support away from the connector, so that the grip is offset from the skid body in the height direction of the roller bed body through the connector and the support, thereby making the grip easy to set and easy for the operator to hold.

[0022] In some embodiments, the number of handle structures is multiple, and the multiple handle structures are spaced apart along the length direction of the roller bed body.

[0023] According to the above-mentioned technical means, by arranging multiple handle structures at intervals along the length direction of the roller bed body, the first skid mechanism has multiple handle structures along the length direction of the roller bed body. The operator can move the first skid mechanism by holding any one of the handle structures, which further improves the convenience of moving the first skid mechanism, thereby further improving the ease of operation of the transmission device.

[0024] In some embodiments, the first skid mechanism further includes a first support member and a second support member, both of which are connected to the skid body and are spaced apart along the length of the roller bed body to support the vehicle body structure; the first skid mechanism further includes a positioning member connected to the skid body to position the vehicle body structure.

[0025] According to the above technical means, since both the first support member and the second support member are connected to the skid body, and the first support member and the second support member are spaced apart along the length direction of the roller bed body, the vehicle body structure can be supported by the first support member and the second support member, thereby making the vehicle body structure stably set on the first skid mechanism; in addition, since the first skid mechanism also includes a positioning member connected to the skid body, the vehicle body structure can be positioned by the positioning member, so that the position of the vehicle body structure relative to the first skid mechanism is accurate, thereby further improving the processing accuracy of the vehicle body structure.

[0033] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0034] like Figures 1 to 4 As shown, this application provides a transmission device for transmitting a vehicle body structure. For example, the vehicle body structure may be a floor assembly, a body-in-white structure, or a vehicle frame.

[0035] The transmission device includes a roller bed mechanism 1, a first skid mechanism 2, a second skid mechanism 3, a first positioning member 4, and a second positioning member 5. The roller bed mechanism 1 includes a roller bed body 10, a second limiting component 12, and a third limiting component 13. Along the length direction of the roller bed body 10, the roller bed body 10 includes a first station, a second station, and a third station arranged sequentially. The second limiting component 12 and the third limiting component 13 are both located at the second station, and the second limiting component 12 and the third limiting component 13 are arranged along the width direction of the roller bed body 10. The first skid mechanism 2 and the second skid mechanism 3 are both slidably connected to the roller bed body 10, and the first skid mechanism 2 can move between the first station and the second station, and the second skid mechanism 3 can move between the second station and the third station.

[0036] It should be explained that the distance between the first station, the second station and the third station of the roller bed body 10 can be determined according to the production and processing needs, and this application embodiment does not limit this.

[0037] Furthermore, the first positioning member 4 is connected to the first skid mechanism 2, and the second positioning member 5 is connected to the second skid mechanism 3. Along the length direction of the roller bed body 10, the projection of the first positioning member 4 is located outside the projection of the third limiting component 13, and the projection of the first positioning member 4 coincides with at least a portion of the projection of the second limiting component 12. The projection of the second positioning member 5 is located outside the projection of the second limiting component 12, and the projection of the second positioning member 5 coincides with at least a portion of the projection of the third limiting component 13.

[0038] When the first skid mechanism 2 slides from the first station to the second station, along the length direction of the roller bed body 10, the projection of the first positioning member 4 is outside the projection of the third limiting component 13. The first positioning member 4 can avoid the third limiting component 13 and is limited by the second limiting component 12, thereby keeping the first skid mechanism 2 at the second station. When the second skid mechanism 3 slides from the third station to the second station, along the length direction of the roller bed body 10, the projection of the second positioning member 5 is outside the projection of the second limiting component 12. The second positioning member 5 can avoid the second limiting component 12 and is limited by the third limiting component 13, thereby keeping the second skid mechanism 3 at the second station.

[0039] Since both the second limiting component 12 and the third limiting component 13 are located at the second station, and are arranged along the width direction of the roller bed body 10; the projection of the first positioning member 4 is outside the projection of the third limiting component 13, and at least part of the projection of the first positioning member 4 coincides with the projection of the second limiting component 12; the projection of the second positioning member 5 is outside the projection of the second limiting component 12, and at least part of the projection of the second positioning member 5 coincides with the projection of the third limiting component 13. In this way, when the first skid mechanism 2 slides to the second station, the first positioning member 4 can avoid the third limiting component 13, preventing interference when the first skid mechanism 2 slides to the second station. Similarly, interference can be prevented when the second skid mechanism 3 slides to the second station, thus ensuring smooth sliding of the first skid mechanism 2 and the second skid mechanism 3. In addition, the first skid mechanism 2 can be limited and held at the second station by the second limiting component 12, and the second skid mechanism 3 can also be limited and held at the second station by the third limiting component 13, so that the positioning process when the first skid mechanism 2 and the second skid mechanism 3 slide to the second station is simple and convenient, and can be used for manual operation.

[0040] In some embodiments, such as Figures 2 to 4 As shown, the third limiting component 13 includes a first sub-component 131 and a second sub-component 132, which are spaced apart along the width direction of the roller bed body 10. The second limiting component 12 is located between the first sub-component 131 and the second sub-component 132. The second positioning member 5 includes a first sub-positioning member 51 and a second sub-positioning member 52, which are spaced apart along the width direction of the roller bed body 10. Along the length direction of the roller bed body 10, the projection of the first sub-positioning member 51 at least partially coincides with the projection of the first sub-component 131, and the projection of the second sub-positioning member 52 at least partially coincides with the projection of the second sub-component 132.

[0041] For example, along the length of the roller bed body 10, the projection of the first sub-positioning member 51 completely or partially coincides with the projection of the first sub-assembly 131, and the projection of the second sub-positioning member 52 completely or partially coincides with the projection of the second sub-assembly 132. In some examples, the projection of the first sub-positioning member 51 completely coincides with the projection of the first sub-assembly 131, and the projection of the second sub-positioning member 52 completely coincides with the projection of the second sub-assembly 132.

[0042] For example, the first sub-positioning member 51 and the second sub-positioning member 52 can be plate-shaped, block-shaped, or rod-shaped structures; the connection method between the first positioning member 4 and the second sub-positioning member 52 and the second skid mechanism 3 can be welding, riveting, bolting, etc., and this application embodiment does not limit this.

[0043] In some examples, the first sub-positioning member 51 and the second sub-positioning member 52 are block structures. The second skid mechanism 3 includes a mounting plate 31. The mounting plate 31 has a first mounting groove and a second mounting groove on the side facing the roller bed body 10. The first mounting groove and the second mounting groove are spaced apart along the width direction of the roller bed body 10. The first sub-positioning member 51 and the second sub-positioning member 52 are located in the first mounting groove and the second mounting groove, respectively, and are fixedly connected to the mounting plate 31 by fasteners.

[0044] It should be noted that a third mounting groove can also be provided on the side of the mounting plate 31 facing the roller bed body 10. The third mounting groove is located between the first mounting groove and the second mounting groove, and the first positioning member 4 can be installed in the third mounting groove. In this way, if the first positioning member 4 is only provided in the third mounting groove, then the second skid mechanism 3 can be used as the first skid mechanism 2, so that it can move between the first station and the second station, thus making the second skid mechanism 3 used as the first skid mechanism 2. Then, the first skid mechanism 2 can be set with reference to the structure of the second skid described above, so that the first skid mechanism 2 can also be used as the second skid mechanism 3.

[0045] Since the third limiting component 13 includes a first sub-component 131 and a second sub-component 132, which are spaced apart along the width direction of the roller bed body 10, and the second positioning member 5 includes a first sub-positioning member 51 and a second sub-positioning member 52, with at least a partial overlap between the projection of the first sub-positioning member 51 and the projection of the second sub-positioning member 52 and the projection of the second sub-positioning member 52, when the second skid mechanism 3 is located at the second station, the first positioning member 4 limits it through the first sub-component 131 and the second sub-component 132, so that both ends of the second skid mechanism 3 can be limited in the width direction of the roller bed body 10. This makes the force on the second skid mechanism 3 more uniform after it is limited at the second station, further improving the stability of the second skid mechanism 3 in positioning on the roller bed body 10.

[0046] In some other embodiments, the third limiting component 13 includes only the first sub-component 131, and the second positioning member 5 includes only the first sub-positioning member 51. In the width direction of the roller bed body 10, the first sub-component 131 is located on one side of the second limiting component 12. In addition, along the length direction of the roller bed body 10, the first sub-positioning member 51 partially overlaps with the first sub-component 131.

[0047] In some embodiments, such as Figures 2 to 4 As shown, the first sub-assembly 131 includes a first limiting member 131a and a first locking member 131b. The first limiting member 131a is fixedly connected to the roller bed body 10, and the first locking member 131b is located on the side of the first limiting member 131a near the third station. The first locking member 131b is movably connected to the roller bed body 10 along the height direction of the roller bed body 10. The second sub-assembly 132 includes a second limiting member 132a and a second locking member 132b. The second limiting member 132a... The first sub-positioning member 51 is fixedly connected to the roller bed body 10. The second locking member 132b is located on the side of the second limiting member 132a near the third station, and the second locking member 132b is movably connected to the roller bed body 10 along the height direction of the roller bed body 10. When the second skid mechanism 3 is located in the second station, the first sub-positioning member 51 is located between the first limiting member 131a and the first locking member 131b, and the second sub-positioning member 52 is located between the second limiting member 132a and the second locking member 132b.

[0048] For example, the first limiting member 131a can be a plate-like structure, a rod-like structure, or a block-like structure, as long as it can be fixedly connected to the roller bed body 10. This application embodiment does not impose any restrictions on this. For example, the first limiting member 131a is a block-like structure, and the first limiting member 131a is fixedly connected to the roller bed body 10 by fasteners.

[0049] For example, the first locking member 131b can be powered by itself. For instance, the first locking member 131b includes a telescopic member and a locking block. The telescopic member includes a fixed end and a telescopic section. The fixed end of the telescopic member is fixedly connected to the roller bed body 10, and the telescopic end is fixedly connected to the locking block, thereby causing the locking block to move along the height direction of the roller bed body 10. Specifically, the telescopic member can be a cylinder, a hydraulic cylinder, or a telescopic motor, etc.

[0050] As another example, the first locking member 131b can also be unpowered and move relative to the roller bed body 10 by manual operation. For example, the first locking member 131b is a rod and is slidably connected to the roller bed body 10, and can be moved along the height direction of the roller bed body 10 by manual operation.

[0051] The second limiting member 132a and the second locking member 132b can be configured with reference to the first limiting member 131a and the first locking member 131b described above, and will not be described in detail here.

[0052] When the second skid mechanism 3 moves from the third station to the second station, the first sub-positioning member 51 contacts the first limiting member 131a on the side facing the first station, and then the first locking member 131b moves toward the first sub-positioning member 51 and is located on the side facing the third station, so that the first sub-positioning member 51 is located between the first limiting member 131a and the first locking member 131b. Similarly, the second sub-positioning member 52 is located between the second limiting member 132a and the second locking member 132b.

[0053] Since the first sub-assembly 131 includes a first limiting member 131a and a first locking member 131b, and the second sub-assembly 132 includes a second limiting member 132a and a second locking member 132b, the first locking member 131b is movably connected to the roller bed body 10 along the height direction, and the second locking member 132b is movably connected to the roller bed body 10 along the height direction, when the second skid mechanism 3 moves to the second station, the first sub-positioning member 51 contacts the first limiting member 131a, and the second sub-positioning member 51... When 52 contacts the second limiting member 132a, the second skid mechanism 3 can be positioned. Then, the first locking member 131b and the second locking member 132b are moved upwards towards the roller bed body 10, so that the first sub-positioning member 51 is located between the first limiting member 131a and the first locking member 131b, and the second sub-positioning member 52 is located between the second limiting member 132a and the second locking member 132b. This allows the second skid mechanism 3 to be stably maintained at the second working position, further improving the convenience of positioning the first skid mechanism 2 and the second skid mechanism 3.

[0054] In some other embodiments, the first sub-positioning member 51 and the second sub-positioning member 52 are block structures. The first sub-assembly 131 includes only the first locking member 131b, and the second sub-assembly 132 includes only the second locking member 132b. The first locking member 131b and the second locking member 132b are movably connected to the roller bed body 10 along the height direction of the roller bed body 10. The upper ends of the first locking member 131b and the second locking member 132b are provided with snap-fit ​​grooves. When the second skid mechanism 3 is located in the second working position, the first locking member 131b and the second locking member 132b move toward the upper part of the roller bed body 10, and the first sub-positioning member 51 and the second sub-positioning member are embedded in the snap-fit ​​grooves.

[0055] In some embodiments, such as Figures 2 to 4As shown, the second limiting component 12 includes a third limiting member 121 and a third locking member 122. The third limiting member 121 is fixedly connected to the roller bed body 10, and the third locking member 122 is located on the side of the third limiting member 121 near the first station. The third locking member 122 is movably connected to the roller bed body 10 along the height direction of the roller bed body 10. When the first skid mechanism 2 is located at the second station, the first positioning member 4 is located between the third limiting member 121 and the third locking member 122.

[0056] For example, the third limiting member 121 can be set with reference to the first limiting member 131a described above, and the third locking member 122 can be set with reference to the first locking member 131b described above. This embodiment of the application will not be described in detail here.

[0057] Furthermore, the first limiting member 131a, the third limiting member 121, and the second limiting member 132a are arranged sequentially along the width direction of the roller bed body 10, and the first locking member 131b, the third locking member 122, and the second locking member 132b are arranged sequentially along the width direction of the roller bed body 10.

[0058] For example, the distance between the third limiting member 121 and the first limiting member 131a can be greater than the distance between the third limiting member 121 and the second limiting member 132a, or it can be less than or equal to the distance between the third limiting member 121 and the second limiting member 132a; the distance between the third locking member 122 and the first locking member 131b can be greater than the distance between the third locking member 122 and the second locking member 132b, or it can be less than or equal to the distance between the third locking member 122 and the second locking member 132b.

[0059] In some examples, the third limiting member 121 and the third locking member 122 are located at the middle of the width direction of the roller bed body 10, the distance between the third limiting member 121 and the first limiting member 131a is equal to the distance between the third limiting member 121 and the second limiting member 132a, and the distance between the third locking member 122 and the first locking member 131b is equal to the distance between the third locking member 122 and the second locking member 132b.

[0060] Since the second limiting component 12 includes a third limiting member 121 and a third locking member 122, the first limiting member 131a, the third limiting member 121, and the second limiting member 132a are arranged sequentially along the width direction of the roller bed body 10, and the first locking member 131b, the third locking member 122, and the second locking member 132b are arranged sequentially along the width direction of the roller bed body 10. This allows the second limiting component 12 to be positioned between the first sub-component 131 and the second sub-component 132, utilizing the space between the first sub-component 131 and the second sub-component 132, resulting in a more compact layout and a more rational structural design for the second limiting component 12 and the third limiting component 13.

[0061] In some other embodiments, the third limiting member 121, the first limiting member 131a, and the second limiting member 132a are arranged sequentially along the width direction of the roller bed body 10, and the third locking member 122, the first locking member 131b, and the second locking member 132b are arranged sequentially along the width direction of the roller bed body 10.

[0062] In some embodiments, such as Figures 2 to 4 As shown, the rolling bed mechanism 1 also includes a first limiting component 11 and a fourth limiting component 14. The first limiting component 11 is located at the first station, and at least a portion of the projection of the first positioning member 4 coincides with the projection of the first limiting component 11 along the length direction of the rolling bed. The fourth limiting component 14 is located at the third station, and at least a portion of the projection of the second positioning member 5 coincides with the projection of the fourth limiting component 14 along the length direction of the rolling bed.

[0063] For example, along the length of the roller bed body 10, the projection of the first positioning member 4 completely or partially coincides with the projection of the first limiting component 11, and the projection of the second positioning member 5 completely or partially coincides with the projection of the fourth limiting component 14. In some examples, the projection of the first positioning member 4 completely coincides with the projection of the first limiting component 11, and the projection of the second positioning member 5 completely coincides with the projection of the fourth limiting component 14.

[0064] When the first skid mechanism 2 moves to the first station, the first positioning member 4 can be limited by the first limiting component 11, so that the first skid mechanism 2 is kept at the first station; when the second skid mechanism 3 moves to the third station, the second positioning member 5 can be limited by the fourth limiting component 14, so that the second skid mechanism 3 is kept at the third station.

[0065] Since the first limiting component 11 is located at the first station and the fourth limiting component 14 is located at the third station, and at least a portion of the projection of the first positioning member 4 coincides with the projection of the first limiting component 11 along the length direction of the roller bed; and at least a portion of the projection of the second positioning member 5 coincides with the projection of the fourth limiting component 14 along the length direction of the roller bed, the first skid mechanism 2 can be limited by the first limiting component 11 at the first station, and the second skid mechanism 3 can be limited by the fourth limiting component 14 at the third station. This allows the first skid mechanism 2 to be accurately positioned and maintain a stable position at the first station, and the second skid mechanism 3 to be accurately positioned and maintain a stable position at the third station. This adapts to multi-station processing on the production line and improves the applicability of the transmission device.

[0066] In some embodiments, such as Figures 2 to 4 As shown, along the length of the roller bed, the projection of the first limiting component 11 is located within the projection of the gap between the first sub-component 131 and the second sub-component 132.

[0067] For example, the first limiting component 11 includes a fourth limiting member 111 and a fourth locking member 112. The fourth limiting member 111 is fixedly connected to the roller bed body 10, and the fourth locking member 112 is located on the side of the fourth limiting member 111 near the second station. The fourth locking member 112 is movably connected to the roller bed body 10 along the height direction of the roller bed body 10. Along the length direction of the roller bed, the projections of the fourth limiting member 111 and the fourth locking member 112 are both located within the projection of the gap between the first sub-component 131 and the second sub-component 132.

[0068] In some examples, the specific configuration of the fourth limiting member 111 can refer to the third limiting member 121 described above, and the specific configuration of the fourth locking member 112 can refer to the third locking member 122 described above. The embodiments of this application will not be described in detail here.

[0069] In addition, the fourth limiting component 14 includes a third sub-component 141 and a fourth sub-component 142, which are spaced apart along the width direction of the roller bed body 10. Along the length direction of the roller bed body 10, the projection of the first sub-positioning member 51 at least partially coincides with the projection of the third sub-component 141, and the projection of the second sub-positioning member 52 at least partially coincides with the projection of the fourth sub-component 142.

[0070] In some examples, the specific settings of the third sub-component 141 can refer to the first sub-component 131 described above, and the specific settings of the fourth sub-component 142 can refer to the second sub-component 132 described above. The embodiments of this application will not be described in detail here.

[0071] Since the third sub-component 141 and the fourth sub-component 142 are spaced apart along the width direction of the roller bed body 10, and along the length direction of the roller bed body 10, the projection of the first sub-positioning member 51 coincides at least partially with the projection of the third sub-component 141, and the projection of the second sub-positioning member 52 coincides at least partially with the projection of the fourth sub-component 142, when the second skid mechanism 3 is in the third station, the first sub-positioning member 51 is limited by the third sub-component 141, and the second sub-positioning member 52 is limited by the fourth sub-component 142, thereby making the second skid mechanism 3 stable in the third station and further improving the stability of the second skid mechanism 3 in the positioning on the roller bed body 10.

[0072] In some embodiments, such as Figures 5 to 7 As shown, the first skid mechanism 2 includes a skid body 21 and a handle structure 22 connected to the skid body 21. The skid body 21 is slidably connected to the roller bed body 10.

[0073] For example, the rolling bed mechanism 1 includes multiple rotating rollers disposed on the rolling bed body 10 and spaced apart along the length of the rolling bed body 10. A skid body 21 is disposed on the drive rollers, thereby slidably connected to the rolling bed body 10. As another example, the rolling bed mechanism 1 includes a slide rail disposed along the length of the rolling bed body 10. The skid body 21 includes a sliding block slidably connected to the slide rail, thereby slidably connecting the skid body 21 to the rolling bed body 10.

[0074] In some examples, the skid body 21 includes a first sliding rod 211, a second sliding rod 212, and a fixed plate 213. The first sliding rod 211 and the second sliding rod 212 are arranged parallel to each other along the length direction of the roller bed body 10. The fixed plate 213 is connected between the first sliding rod 211 and the second sliding rod 212. The roller bed mechanism 1 includes a plurality of rotating rollers, which are spaced apart along the length direction of the roller bed body 10. The first sliding rod 211 and the second sliding rod 212 are disposed on the rotating rollers, thereby making the skid body 21 slidably connected to the roller bed body 10.

[0075] Since the first skid mechanism 2 includes a skid body 21 and a handle structure 22 connected to the skid body 21, the skid body 21 is slidably connected to the roller bed body 10. In this way, the operator can hold the handle structure 22 to slide the skid body 21 along the length direction of the roller bed body 10, thereby enabling the first skid mechanism 2 to move between the first station and the second station, improving the ease of operation of the transmission device.

[0076] In some embodiments, such as Figures 5 to 7 As shown, the handle structure 22 includes a connector 221, a support 222, and a grip 223. The connector 221 is connected to the skid body 21, the support 222 is connected to the upper end of the connector 221, and the grip 223 is connected to the end of the support 222 away from the connector 221.

[0077] For example, the connector 221 and the support 222 can be plate-like structures, rod-like structures or irregular structures, and the embodiments of this application do not limit this.

[0078] In some examples, the connector 221, the support 222, and the gripper 223 are rods. The connector 221 is arranged along the length direction of the roller bed body 10, and the support 222 is arranged along the height direction of the roller bed body 10. One end of the connector 221 is connected to the upper side of the fixing plate 213, and the other end of the connector 221 is connected to the lower end of the support 222. The gripper 223 is arranged along the width direction of the roller bed body 10, and the middle part of the gripper 223 is fixedly connected to the upper end of the support 222.

[0079] Since the handle structure 22 includes a connector 221, a support 222, and a grip 223, the connector 221 is connected to the skid body 21, the support 222 is connected to the upper end of the connector 221, and the grip 223 is connected to the end of the support 222 away from the connector 221, the grip 223 is offset from the skid body 21 in the height direction of the roller bed body 10 through the connector 221 and the support 222, so that the grip 223 is easy to set and easy for the operator to hold.

[0080] In some embodiments, such as Figures 5 to 7 As shown, there are multiple handle structures 22, which are spaced apart along the length of the roller bed body 10.

[0081] For example, the number of handle structures 22 can be 2 to 8, such as 2, 6 or 8 handle structures 22.

[0082] In some examples, the skid body 21 includes six fixed plates 213, which are spaced apart along the length of the roller bed body 10. There are six handle structures 22, which are fixedly connected to the six fixed plates 213 respectively.

[0083] In this embodiment, multiple handle structures 22 are spaced apart along the length of the roller bed body 10, so that the first skid mechanism 2 has multiple handle structures 22 along the length of the roller bed body 10. The operator can move the first skid mechanism 2 by holding any one of the handle structures 22, which further improves the convenience of moving the first skid mechanism 2, thereby further improving the ease of operation of the transmission device.

[0084] In some embodiments, such as Figures 5 to 7 As shown, the first skid mechanism 2 also includes a first support member 23 and a second support member 24. The first support member 23 and the second support member 24 are both connected to the skid body 21, and the first support member 23 and the second support member 24 are spaced apart along the length direction of the roller bed body 10 to support the vehicle body structure.

[0085] For example, the first support member 23 and the second support member 24 can be a block structure, a column structure or an irregular structure, as long as they can support the vehicle body structure. This application embodiment does not limit this.

[0086] In some examples, the first support member 23 includes a first support column and a second support column, which are spaced apart along the width direction of the roller bed body 10. The lower ends of the first and second support columns are fixedly connected to the skid body 21, and the upper ends of the first and second support columns are provided with elastic pads. Furthermore, the specific structure of the second support member 24 can refer to the design of the first support member 23 described above, and will not be repeated here.

[0087] In addition, the first skid mechanism 2 also includes a positioning element 25, which is connected to the skid body 21 and is used to position the vehicle body structure.

[0088] For example, the positioning component 25 can be a column-shaped structure, a rod-shaped structure, or an irregular shape, as long as it can be connected to the vehicle body structure to position the vehicle body structure.

[0089] In some examples, the positioning element 25 includes a first positioning pin and a second positioning pin, which are spaced apart along the width direction of the roller bed body 10. The lower ends of the first positioning pin and the second positioning pin are fixedly connected to the skid body 21, and the upper ends of the first positioning pin and the second positioning pin are inserted into the vehicle body structure, thereby realizing the positioning of the vehicle body structure.

[0090] Since the first support member 23 and the second support member 24 are both connected to the skid body 21, and the first support member 23 and the second support member 24 are spaced apart along the length of the roller bed body 10, the vehicle body structure can be supported by the first support member 23 and the second support member 24, thereby making the vehicle body structure stably set on the first skid mechanism 2; in addition, since the first skid mechanism 2 also includes a positioning member 25, which is connected to the skid body 21, the vehicle body structure can be positioned by the positioning member 25, so that the position of the vehicle body structure relative to the first skid mechanism 2 is accurate, thereby further improving the processing accuracy of the vehicle body structure.

[0091] It should be noted that the second skid mechanism 3 can be configured with a handle structure 22, a first support member 23, a second support member 24 and a positioning member 25, which will not be described in detail here.
