Description

Technical Field

[0001] This utility model relates to the field of logistics and transportation technology, and in particular to a transfer device for electric vehicle production. Background Technology

[0002] Transfer devices play a crucial role in the manufacturing process of electric vehicles. They are primarily used to transfer parts, semi-finished products, or finished products between different stages of the production line or between workshops, ensuring an efficient and smooth production flow. In electric vehicle production, multiple workshops are responsible for different manufacturing stages. For example, battery assembly, frame welding, and tire installation are all carried out in different production areas. After each workshop completes its work, the parts or semi-finished products need to be promptly transferred to the next stage.

[0003] However, some existing electric vehicle production transfer devices typically use traditional planar transfer devices with forklifts or AGVs for horizontal transport. However, they do not take into account the limitations of ground track layout, which restricts movement to a two-dimensional plane. This makes it difficult to meet the material distribution needs of multi-level workstations and three-dimensional warehousing in electric vehicle production workshops. Furthermore, planar transport occupies a large amount of production space, resulting in low logistics efficiency.

[0004] Therefore, a transfer device for electric vehicle production is proposed to address the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a transfer device for electric vehicle production, which aims to improve the problem in the prior art that the workpiece cannot be transported to a suitable height during transportation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A transfer device for electric vehicle production includes a frame, characterized in that: a transport mechanism is provided at the top of the frame, the transport mechanism comprising:

[0008] The lifting assembly includes support frames fixedly connected to the front and rear sides of the top of the frame, electric push rods fixedly connected to the bottom of the two support frames, multiple guide rods fixedly connected to the bottom of the two support frames, a bearing plate slidably connected to the outside of the multiple guide rods, the front and rear sides of the top of the bearing plate being fixedly connected to the output ends of the two electric push rods respectively, a clamping assembly for clamping and fixing the electric vehicle being provided on the top of the bearing plate, stabilizing assemblies for fixing the frame being provided on the front and rear sides of the bottom of the frame, and moving assemblies for moving being fixedly connected to the four corners of the bottom of the frame.

[0009] The movable component includes movable wheels that are fixedly connected to the four corners of the bottom of the frame;

[0010] As a further description of the above technical solution:

[0011] The clamping assembly includes four electric guide rails and four sliding blocks. Two of the electric guide rails are fixedly connected to the top front side of the support plate at their bottom, and the other two electric guide rails are fixedly connected to the bottom rear side of the support plate at their bottom. The middle part of each sliding block is slidably connected to the outside of the electric guide rails. The sliding blocks are arranged in pairs, and a clamping plate is fixedly connected to the side of each pair of sliding blocks that are close to each other.

[0012] As a further description of the above technical solution:

[0013] The stabilizing component includes two receiving shells fixedly connected to the front and rear sides of the bottom of the frame, respectively. Each of the two receiving shells has a cavity inside. Multiple dampers are fixedly connected to the top inner wall of each of the two cavities. A sliding plate is slidably connected inside the cavity. One end of a spring sleeved on the damper is fixedly connected to the top of the sliding plate. The other end of the spring is fixedly connected to the top inner wall of the cavity. A force transmission plate is fixedly connected to the bottom of the sliding plate. A stabilizing plate is fixedly connected to the bottom of the force transmission plate.

[0014] As a further description of the above technical solution:

[0015] The support plate has multiple holes on its exterior, and all of the holes are slidably connected to the exterior of the guide rod. Two of the holes are threaded to the bottom of the electric push rod by having internal threads inside.

[0016] As a further description of the above technical solution:

[0017] The bottom of the support plate is in contact with the bottom of the frame, and the stabilizing plate is located below the moving wheel;

[0018] As a further description of the above technical solution:

[0019] The bottoms of the multiple dampers are fixedly connected to the top of the sliding plate, and the bottom of the sliding plate is in contact with the bottom inner wall of the cavity.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this invention, a lifting assembly driven by a threaded rod and a clamping assembly controlled by an electric guide rail work together to achieve three-dimensional dynamic transportation of electric vehicles. The electric push rod enables the support plate to rise and fall smoothly in the vertical direction, breaking through the spatial limitations of traditional planar transportation. Simultaneously, the electric guide rail drives the sliding block to slide horizontally along the support plate, driving the clamping plates to move in opposite directions, quickly completing the adaptive clamping of the electric vehicle. This structural linkage allows the device to flexibly adjust the transportation height according to production needs, and ensures the stability of the vehicle during transportation through the dynamic clamping force of the clamping plates. Through the coordinated design of vertical transportation and horizontal clamping, the utilization rate of workshop space is effectively improved.

[0022] 2. In this utility model, the stabilizing component adopts a composite buffer structure of damper and spring, combined with the linkage design of force transmission plate and stabilizing plate, to achieve dynamic stability during loading. When the load-bearing plate descends to the point where the stabilizing plate touches the ground, the force transmission plate transmits pressure to the sliding plate, compressing the damper and spring. The hydraulic buffer of the damper and the elastic deformation of the spring absorb the impact energy, allowing the frame to be smoothly lifted and the moving wheels to leave the ground. This multi-stage buffering mechanism effectively reduces vibration and impact during loading, prevents the device from swaying, and ensures the safety of operators. At the same time, the contact support between the stabilizing plate and the ground enhances the overall stability of the device, preventing the risk of tipping over due to center of gravity shift.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1 to 2 This utility model provides an embodiment of a transfer device for electric vehicle production, comprising a frame 1, which serves as the main support structure and integrates transportation, stabilization, and movement components. A transportation mechanism is provided at the top of the frame 1, and the transportation mechanism includes:

[0031] The lifting assembly includes a frame 1 with support frames 2 fixedly connected to both the front and rear sides of the top. The support frames 2 fix the top of the frame 1 and support the electric push rod 3, threaded rod 4, and guide rod 5. The bottom plates of both support frames 2 are fixedly connected to the electric push rod 3, which provides the lifting power for the load-bearing plate 6. Vertical displacement of the load-bearing plate 6 is achieved through the electric push rod 3. Multiple guide rods 5 are fixedly connected to the bottom of both support frames 2, constraining the lifting trajectory of the load-bearing plate 6 and ensuring smooth movement. Multiple guide rods 5 are slidably connected to a support plate 6. The top front and rear sides of the support plate 6 are fixedly connected to the output ends of two electric push rods 4 respectively. The top of the support plate 6 is provided with a receiving hole 10 to fix the electric vehicle. Multiple holes 4 are opened on the outside of the support plate 6. Multiple holes 4 are slidably connected to the outside of the guide rods 5. Two of the holes 4 are threaded to the bottom of the electric push rod 3 by opening internal threads. The top of the support plate 6 is provided with a clamping assembly for clamping and fixing the electric vehicle. The clamping assembly includes four electric guide rails 7 and four sliding blocks 8. The electric guide rails 7 are installed on the support plate 6 and drive the sliding blocks 8 to move horizontally.

[0032] Two electric guide rails 7 are fixedly connected to the top front side of the support plate 6 at their bottom, and the bottom two electric guide rails 7 are fixedly connected to the bottom rear side of the support plate 6 at their bottom. The middle part of the sliding block 8 is slidably connected to the outside of the electric guide rail 7. The sliding block 8 slides along the electric guide rail 7, driving the clamping plate 9 to open and close. The sliding blocks 8 are arranged in pairs, and the clamping plate 9 is fixedly connected to the side of each pair of sliding blocks 8 that is close to each other. The clamping plate 9 fixes the electric vehicle by moving the sliding blocks 8 towards each other. The bottom front and rear sides of the frame 1 are provided with stabilizing components for fixing the frame 1. The four corners of the bottom of the frame 1 are fixedly connected with moving components for movement. The moving components include moving wheels 18 fixedly connected to the four corners of the bottom of the frame 1. The moving wheels 18 provide the device with the ability to move and support the whole in the unstable state. The bottom of the support plate 6 is in contact with the bottom of the frame 1, and the stabilizing plate 17 is located below the moving wheels 18.

[0033] Reference Figure 1 , Figure 3 and Figure 4 The stabilizing assembly includes two housing shells 11 fixedly connected to the front and rear sides of the bottom of the frame 1, respectively. Each housing shell 11 houses the stabilizing assembly and is fixed to the bottom of the frame 1. Each housing shell 11 has a cavity 12 inside, which constrains the vertical movement of the sliding plate 15 and houses a damper 13 and a spring 14. Multiple dampers 13 are fixedly connected to the inner top walls of both cavities 12, buffering the impact of the stabilizing plate 17 upon contact with the ground and absorbing energy. The sliding plate 15 is slidably connected inside the cavity 12, transmitting pressure to the force transmission plate 16, which in turn links the dampers 13 and the spring 14. The bottoms of the multiple dampers 13 are fixedly connected to the tops of the sliding plates 15, and one end of a spring 14, sleeved on the damper 13, is fixedly connected to the top of the sliding plate 15. The spring 14 assists in buffering and enhances the elastic support of the stabilizing plate 17 upon contact with the ground. The other end of the spring 14 is fixedly connected to the top inner wall of the cavity 12. The bottom of the sliding plate 15 is in contact with the bottom inner wall of the cavity 12. A force transmission plate 16 is fixedly connected to the bottom of the sliding plate 15, and the force transmission plate 16 transmits the pressure of the sliding plate 15 to the stabilizing plate 17. The bottom of the force transmission plate 16 is fixedly connected to the stabilizing plate 17. After the stabilizing plate 17 touches the ground, it lifts the frame 1, so that the moving wheel 18 is suspended in the air to prevent swaying.

[0034] Working principle: When transporting electric vehicles, the wheels are first placed inside the receiving holes 10 at the top of the bearing plate 6, which limit their movement. Then, multiple electric guide rails 7 are activated, causing the sliding blocks 8 to move. As the sliding blocks 8 move, they cause the two clamping plates 9 to move closer together, clamping and fixing the electric vehicle and improving the stability of the device during transportation. After the electric vehicle is transported to a suitable position on the plane, the electric push rod 3 is activated, causing the output end of the electric push rod 3 to lift the bearing plate 6. This allows the device to transport the electric vehicle to a suitable height according to the actual processing requirements, enabling workers to perform further processing and thus improving the working efficiency of the device.

[0035] Once the device is moved to the appropriate position, when the staff needs to load the electric vehicle onto the top of the receiving hole 10, the electric push rod 3 can be activated to lower the support plate 6. As the support plate 6 descends, it will also lower the stabilizing plate 17. When the stabilizing plate 17 contacts the ground, it will press the sliding plate 15 through the force transmission plate 16. The sliding plate 15 will then press the damper 13 and the spring 14. By pressing the damper 13 and the spring 14, the stabilizing plate 17 can make its contact with the ground more stable. After the stabilizing plate 17 contacts the ground, it will lift the moving wheel 18 off the ground, thus preventing the device from shaking when the staff loads the electric vehicle onto the top of the support plate 6.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
