Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, and in particular to a robotic arm for repairing the chassis of new energy vehicles. Background Technology

[0002] With the booming development of the new energy vehicle industry, the maintenance and repair of vehicle chassis are becoming increasingly frequent and complex. New energy vehicle chassis integrate numerous key components, such as battery packs and drive motors, demanding extremely high precision and efficiency in maintenance. To address these challenges, robotic arms for new energy vehicle chassis maintenance have emerged, becoming an important tool for improving the quality and speed of maintenance operations and occupying a crucial position in the entire after-sales maintenance system for new energy vehicles.

[0003] Currently, most robotic arms used for repairing the chassis of new energy vehicles employ relatively conventional mechanical structures. Their joints typically rely on rigid connections, with various components securely assembled together using bolts and other connectors. Technically, they primarily utilize motors to drive gears, linkages, and other transmission mechanisms to achieve the rotation and movement of the robotic arm's joints, thereby performing the gripping, moving, and repair operations on the vehicle chassis components. This traditional structural design and technical principle can, to a certain extent, meet basic repair needs.

[0004] However, existing technologies have certain problems. When the joints of the equipment need to be disassembled and repaired, due to the use of bolts for fixing, maintenance personnel usually have to use specific tools to carefully remove the bolts one by one from the surface of the equipment. This process is extremely cumbersome, requiring maintenance personnel to have certain operating skills and often consuming a lot of time, which seriously affects maintenance efficiency and cannot meet the actual needs of rapid repair of new energy vehicle chassis. Therefore, a new energy vehicle chassis repair robot is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a new energy vehicle chassis maintenance robot, which aims to improve the problem that when traditional equipment joints need to be disassembled and repaired, it is usually necessary to use specific tools to remove the bolts on the surface of the equipment, which can easily lead to a long time consumption.

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

[0007] A new energy vehicle chassis repair robot includes a robotic arm, a joint gripper on one side of the robotic arm, a quick-release assembly between the robotic arm and the joint gripper, a base fixedly connected to the bottom of the robotic arm, a plurality of casters fixedly connected to the bottom of the base, and a support assembly at the bottom of the base.

[0008] The quick-release assembly includes multiple locking balls located between the robotic arm and the articulated gripper. A connecting ring one is rotatably connected to the outer wall of the robotic arm, and a connecting ring two is fixedly connected to one side of the articulated gripper. Connecting shells are fixedly connected to both sides of the inner side of the connecting ring one. The locking balls are slidably connected to the inside of the connecting shells. A fixing shell is fixedly connected to the outer wall of each connecting shell. One side of the fixing shell is fixedly connected to the outer wall of the connecting ring two. The locking balls engage with the inside of the fixing shells. A pushing component is provided on the outer wall of the locking balls for pushing the locking balls to move.

[0009] As a further description of the above technical solution:

[0010] The pushing component includes multiple frustum-shaped locking blocks, each frustum-shaped locking block being located on the outer wall of the locking ball. Each inner wall of the connecting shell is fixedly connected to a fixing ring, and each inner wall of the fixing ring is slidably connected to a transmission column. One end of each transmission column is fixedly connected to a pressing plate, and the other end of each transmission column is fixedly connected to a frustum-shaped locking block. The frustum-shaped locking blocks are in contact with the locking ball.

[0011] As a further description of the above technical solution:

[0012] Each of the connecting shells has a spring 1 on its inner wall. One end of each spring 1 is fixedly connected to the outer wall of the fixing ring, and the other end of each spring 1 is fixedly connected to a connecting ring 3. The inner wall of the connecting ring 3 is fixedly connected to the outer wall of the transmission column 1.

[0013] As a further description of the above technical solution:

[0014] The support assembly includes multiple suction cups located at the bottom of the base, and a push handle is fixedly connected to the top of the base.

[0015] As a further description of the above technical solution:

[0016] The base has multiple connecting cylinders fixedly connected inside, and each connecting cylinder has a connecting post slidably connected inside, extending through to the top of the base. Each connecting post has a handle fixedly connected to its top.

[0017] As a further description of the above technical solution:

[0018] Each of the connecting columns is fixedly connected to a second transmission column at its bottom end, and the bottom of each second transmission column is fixedly connected to the top of the suction cup.

[0019] As a further description of the above technical solution:

[0020] Each of the connecting cylinders has a hook-shaped groove inside, and each of the connecting columns has a slide bar fixedly connected to its outer wall. The slide bar is slidably connected to the inner wall of the hook-shaped groove.

[0021] As a further description of the above technical solution:

[0022] Each of the connecting cylinders is equipped with a second spring. One end of the second spring is fixedly connected to the bottom of the connecting column, and the other end of the second spring is fixedly connected to the inner wall of the connecting cylinder.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the elasticity of the spring pushes the locking ball to engage with the inside of the fixed shell, thereby achieving the installation and disassembly between the robotic arm and the joint gripper. This solves the problem that when traditional equipment joints need to be disassembled and repaired, it is usually necessary to use specific tools to remove the bolts on the surface of the equipment, which can easily lead to a long time consumption. This enhances the portability of the installation and disassembly of the equipment joints.

[0025] 2. In this utility model, the suction cup at the bottom of the transmission column two is pushed by the connecting column to press against the ground, thereby increasing the contact area between the suction cup and the ground. At the same time, the position of the slide bar is fixed by the groove on one side of the hook-shaped slide groove, ensuring that the transmission column two always maintains sufficient pressure on the suction cup, which enhances the firmness between the suction cup and the ground and achieves the effect of fixed connection between the equipment and the ground. This solves the problem that the equipment is prone to displacement due to shaking or accidental collision during use, which affects the accuracy of the equipment. It enhances the stability of the equipment during use. Attached Figure Description

[0032] 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.

[0033] Reference Figures 1-3 An embodiment of this utility model is provided: a new energy vehicle chassis repair robot, including a robotic arm 1, a joint gripper 2 is provided on one side of the robotic arm 1, a quick-release assembly is provided between the robotic arm 1 and the joint gripper 2, a base 4 is fixedly connected to the bottom of the robotic arm 1, a plurality of moving wheels 5 are fixedly connected to the bottom of the base 4, and a support assembly is provided at the bottom of the base 4.

[0034] The quick-release assembly includes multiple locking balls 16, which are located between the robotic arm 1 and the articulated gripper 2, serving as a connection and fixation mechanism. A connecting ring 1 6 is rotatably connected to the outer wall of the robotic arm 1, allowing the robotic arm 1 to rotate flexibly during operation. A connecting ring 2 7 is fixedly connected to one side of the articulated gripper 2, ensuring the stability and reliability of the articulated gripper 2. Connecting shells 10 are fixedly connected to both sides inside the connecting ring 1 6, forming the basis of the connection structure. The locking balls 16 are slidably connected inside the connecting shells 10 to facilitate free movement during disassembly or installation. A fixing shell 9 is fixedly connected to the outer wall of each connecting shell 10, providing additional support and protection. One side of the fixing shell 9 is fixedly connected to the outer wall of the connecting ring 2 7, enhancing the overall structural stability. The locking balls 16 and the interior of the fixing shells 9 engage with each other, effectively maintaining the stability of the connection. The outer wall of the ball 16 is equipped with a pushing component for moving the ball 16, thereby enabling quick disassembly and installation. The pushing component includes multiple frustum-shaped locking blocks 15, each located on the outer wall of the ball 16, effectively pushing the ball 16 to move for easy operation. A fixing ring 13 is fixedly connected to the inner wall of each connecting shell 10, providing mechanical support and positioning. A transmission column 14 is slidably connected to the inner wall of each fixing ring 13, transmitting motion and force. A pressing plate 8 is fixedly connected to one end of each transmission column 14, allowing the operator to directly apply pressure. Each drive column 14 has a frustum-shaped locking block 15 fixedly connected to its other end. The frustum-shaped locking block 15 fits against the locking ball 16 to ensure the effectiveness of the push. Each connecting shell 10 has a spring 12 on its inner wall. The function of the spring 12 is to provide a return force for the connecting structure. One end of each spring 12 is fixedly connected to the outer wall of the fixing ring 13 to stabilize the position of the component. The other end of each spring 12 is fixedly connected to a connecting ring 11. The inner wall of the connecting ring 11 is fixedly connected to the outer wall of the drive column 14 to form a complete transmission component, ensuring the convenience and efficiency of the quick-release component during use.

[0035] Specifically, during equipment use, after moving the equipment to the designated position, the user needs to press down on the handle 18. Pressing the handle 18 causes the transmission column 23 at one end of the connecting column 17 to apply pressure to the suction cup 24, significantly enhancing the adhesion between the suction cup 24 and the ground. During the pressing process, the slider 20 slides on the inner wall of the hook-shaped groove 21, simultaneously pushing the spring 22 to compress. When the slider 20 slides to one side of the hook-shaped groove 21, the user should then rotate the handle 18 to allow the slider 20 to move smoothly from one side to the other side of the hook-shaped groove 21. At this point, the user can release the pressure on the handle 18. With the rebound force of the spring 22, the slider 20 engages with the groove on the other side of the inner wall of the hook-shaped groove 21, ensuring that the transmission column 23 at one end of the connecting column 17 always applies sufficient pressure to the suction cup 24, thereby enhancing the overall stability of the equipment and ensuring its safety and reliability during use.

[0036] Reference Figure 1 and Figure 4 The support components include multiple suction cups 24, which are located at the bottom of the base 4, providing a stable support base and ensuring that the device is firmly fixed during use. A push handle 3 is fixedly connected to the top of the base 4 for easy operation and movement by the user. Multiple connecting cylinders 19 are fixedly connected inside the base 4, providing necessary support and guidance for the connection structure. A connecting post 17 is slidably connected inside each connecting cylinder 19 and extends through to the top of the base 4 to facilitate the transmission of force and movement. A handle 18 is fixedly connected to the top of each connecting post 17, allowing the user to directly control the operation of the device through the handle 18. Each connecting post 17 has a transmission post 23 fixedly connected to its bottom end. The transmission post 23 is used to transmit motion to the suction cup 24 to achieve the adsorption function. The bottom of each transmission post 23 is fixedly connected to the top of the suction cup 24, so that the suction cup 24 can produce an adsorption effect when subjected to pressure. Each connecting cylinder 19 has a hook-shaped groove 21 inside. The design of the hook-shaped groove 21 allows the slide bar 20 to slide smoothly, thereby achieving more flexible operation. Each connecting post 17 has a slide bar 20 fixedly connected to its outer wall, and the slide bar 20 slides to connect... The inner wall of the hook-shaped chute 21 provides a stable guide and movement path. Each connecting cylinder 19 is equipped with a second spring 22. The function of the second spring 22 is to provide feedback force to the connecting column 17 to ensure its stability during operation. One end of the second spring 22 is fixedly connected to the bottom of the connecting column 17 to ensure the recovery ability of the connecting column 17 after being subjected to force. The other end of the second spring 22 is fixedly connected to the inner wall of the connecting cylinder 19 to ensure that the equipment can effectively adsorb and remain stable during operation, thereby enhancing the overall safety and reliability.

[0037] Specifically, during the disassembly of the robotic arm 1 and the articulated gripper 2, the pressing plate 8 must first be pressed to push the frustum-shaped locking block 15 at one end of the transmission column 14 away from the outer wall of the locking ball 16. This action provides the necessary space for the locking ball 16 to move smoothly. Simultaneously, as the transmission column 14 moves, it pushes the connecting ring 11 to apply pressure to the spring 12, causing it to compress. Next, the user needs to pull one side of the robotic arm 1. This process utilizes the inner wall of the fixed housing 9 to push the locking ball 16 into the connecting housing 10, allowing the connecting housing 10 to disengage from the fixed housing 9. The inner wall is successfully removed, thus completing the disassembly between the robotic arm 1 and the joint gripper 2. After maintenance and repair, the user needs to insert the fixing shell 9 on one side of the joint gripper 2 into the outer wall of the connecting shell 10. Once the fixing shell 9 is successfully inserted, the user can release the pressure on the pressing plate 8. At this time, with the help of the rebound force of the spring 12, the frustum locking block 15 will move back to the outer wall of the locking ball 16, so that the locking ball 16 and the inside of the fixing shell 9 are locked together, and the connection between the robotic arm 1 and the joint gripper 2 is firmly fixed, thereby enhancing the efficiency and convenience of portable installation and disassembly of the equipment at the joint.

[0038] Working principle: During the use of the equipment, after moving the equipment to the designated position, press down on the handle 18. This will cause the transmission column 23 at one end of the connecting column 17 to squeeze the suction cup 24, enhancing the tightness of the suction cup 24 against the ground. During this process, the slider 20 will slide on the inner wall of the hook-shaped groove 21 and push the spring 22 to compress. Next, rotate the handle 18 to move the slider 20 from one side of the hook-shaped groove 21 to the other side. Then, release the pressure on the handle 18. The rebound force of the spring 22 will push the slider 20 to engage with the groove on the other side of the inner wall of the hook-shaped groove 21, ensuring that the transmission column 23 at one end of the connecting column 17 always maintains a sufficient squeezing effect on the suction cup 24, thus enhancing the stability of the equipment.

[0039] During the disassembly of the robotic arm 1 and the articulated gripper 2, pressing the pressing plate 8 pushes the frustum-shaped locking block 15 at one end of the transmission column 14 to separate from the outer wall of the locking ball 16, providing space for the locking ball 16 to move. During the movement, the transmission column 14 pushes the connecting ring 11 to compress the spring 12. Then, pulling one side of the robotic arm 1, the inner wall of the fixed shell 9 is used to push the locking ball 16 into the connecting shell 10, thus removing the connecting shell 10 from the inner wall of the fixed shell 9, achieving the disassembly effect between the robotic arm 1 and the articulated gripper 2. After maintenance, the fixed shell 9 on one side of the articulated gripper 2 is inserted into the outer wall of the connecting shell 10. At this time, the pressing force on the pressing plate 8 is released, and the rebound force of the spring 12 pushes the frustum-shaped locking block 15 to move back to the outer wall of the locking ball 16, so that the locking ball 16 and the inside of the fixed shell 9 are engaged, achieving the connection and fixation between the robotic arm 1 and the articulated gripper 2, enhancing the portable installation and disassembly of the equipment joints.

[0040] 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.
