[0018] 3. This new energy vehicle chassis repair manipulator has a second protective mechanism. A highly elastic and flexible elastic rod is installed at the key location where the force is concentrated on the mechanical claw arm. The elastic rod has a unique ability to follow the rotation and angle changes of the mechanical claw arm. When a sudden external force impacts, the elastic rod quickly buffers and unloads the force, reducing vibration.

[0019] 4. This new energy vehicle chassis repair manipulator utilizes a first and second protection mechanism to prevent additional load on the motor during movement, reducing the risk of gripper arm vibration.

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but are not to be construed as limiting the present invention.

[0038] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0039] Example 1: See Figures 1-4 The present invention provides a technical solution: a new energy vehicle chassis maintenance manipulator, comprising a base 1, a mechanical claw arm 2 fixedly connected to the upper surface of the base 1, a mechanical claw arm 2 internally rotatably connected to a mechanical claw arm 6, a mechanical claw arm 2 internally rotatably connected to a replacement mechanism 4, a first protective mechanism 3 fixedly connected to the lower surface of the base 1, a second protective mechanism 5 fixedly connected to the outer surface of the mechanical claw arm 2, the first protective mechanism 3 comprising:

[0040] The chassis frame 301, the upper surface of the chassis frame 301 is fixedly connected to the lower surface of the base 1, the lower surface of the chassis frame 301 is fixedly connected with the moving wheel 302, the interior of the chassis frame 301 is plugged with a screw hole armrest 303, the lower surface of the chassis frame 301 is fixedly connected with the first sleeve 307, the internal thread of the first sleeve 307 is connected with the threaded column 304, the lower surface of the threaded column 304 is fixedly connected with the support 305, and the support 305 is used to support the chassis frame 301.

[0041] A through hole 308 is provided inside the chassis frame 301 , and a hexagonal column 306 is fixedly connected to the outer surface of the threaded column 304 . A protective plug 309 is threadedly connected to the outer surface of the threaded column 304 . The protective plug 309 is used to protect the threaded column 304 .

[0042] The screw hole diameter of the screw hole armrest 303 is the same as the diameter of the through hole 1 308, and the diameter of the through hole 1 308 is the same as the top diameter of the threaded column 304. The screw hole armrest 303 is threadedly connected to the threaded column 304, and the upper surface of the hexagonal column 306 is in contact with the lower surface of the first sleeve 307. The through hole 1 308 is plugged into the threaded column 304. The threaded column 304 is used to fix the screw hole armrest 303. When moving through the moving wheel 302, the vibration of the mechanical claw arm 1 2 and the mechanical claw arm 2 6 caused by inertia can be reduced. By removing the screw hole armrest 303, the movement space is optimized and the collision risk is reduced, so that the robot can move more freely and position more accurately, indirectly protecting the claw arm and reducing the vibration caused by restricted movement or collision.

[0043] The working principle of this embodiment is as follows: when using this new energy vehicle chassis repair manipulator, the manipulator is moved horizontally through the screw hole handrail 303 and the moving wheel 302, and after it is moved to the new energy vehicle chassis position, the threaded column 304 is pushed downward by rotating the hexagonal column 306, and the support 305 is pushed downward. At this time, the four groups of supports 305 are symmetrically arranged and adjusted separately, and the first sleeve 307 is threadedly connected to the threaded column 304 to achieve the horizontal adjustment of the chassis frame 301. Support, at this time the threaded column 304 moves downward, and the threaded column 304 moves downward inside the through hole 1 308, thereby releasing the threaded connection with the screw hole armrest 303, so that the screw hole armrest 303 can be disassembled, and the protective plug 309 is clamped with the chassis frame 301 after releasing the threaded connection with the threaded column 304, and protects the through hole 1 308. At this time, the manipulator is used to avoid unnecessary external forces on the mechanical claw arm 1 2 and the mechanical claw arm 2 6 during movement, thereby enhancing its operating stability and avoiding arm tremors.

[0044] Example 2: Please refer to Figure 5-Figure 8 On the basis of the first embodiment, the present invention provides a technical solution: the replacement mechanism 4 includes a rotating block 401, which is rotatably connected to the mechanical claw arm 2 6, and the outer surface of the rotating block 401 is clamped with a slot block 402, and the interior of the slot block 402 is provided with a hemispherical hole 403, and the interior of the rotating block 401 is provided with a first slot 404, and the interior of the first slot 404 is clamped with a first connecting rod 405, and the outer surface of the first connecting rod 405 is fixedly connected to a spherical column 406, and the outer surface of the spherical column 406 is fixedly connected to a first spring 407, and the spherical column 406 is used to horizontally position the rotating block 401 and the slot block 402.

[0045] The replacement mechanism 4 also includes a threaded rod 408, the outer surface of the threaded rod 408 is threadedly connected to a nut 409, the threaded rod 408 is threadedly connected to the rotating block 401 and the slot block 402, the nut 409 is engaged with the rotating block 401 and the slot block 402, and the threaded rod 408 and the nut 409 are used to horizontally fix the rotating block 401 and the slot block 402.

[0046] The hemispherical hole 403 is engaged with the spherical column 406, the outer surface of the first spring 407 is fixedly connected to the inner wall of the rotating block 401, the spherical column 406 is slidably connected to the rotating block 401, and the first connecting rod 405 is used to limit the spherical column 406. The replacement of the slot block 402 is achieved through the replacement mechanism 4 to adapt to the requirements of different loads and working conditions. The positioning of the hemispherical hole 403 and the spherical column 406 and the fixation of the threaded rod 408 and the nut 409 provide protection for the mechanical claw arm 1 2 and the mechanical claw arm 2 6 and provide stable grasping.

[0047] The second protection mechanism 5 includes an L-shaped frame 501, which is fixedly connected to the outer surface of the mechanical claw arm 2, and the lower surface of the L-shaped frame 501 is fixedly connected to the rotating frame 502, and the outer surface of the rotating frame 502 is rotatably connected to the auxiliary wheel 503, the outer surface of the mechanical claw arm 2 6 is fixedly connected to the rotating shaft seat 504, and the outer surface of the rotating shaft seat 504 is rotatably connected to the rotating sleeve 505, and the outer surface of the rotating sleeve 505 is fixedly connected to the second connecting rod 506, and the outer surface of the second connecting rod 506 is slidably connected to the limiting sleeve 507, and the outer surface of the limiting sleeve 507 is fixedly connected to the second spring 508, and the second connecting rod 506 is used to support the mechanical claw arm 2 6.

[0048] The auxiliary wheel 503 is flush with the moving wheel 302, the limiting sleeve 507 is rotatably connected to the L-shaped frame 501, the lower surface of the second spring 508 is fixedly connected to the upper surface of the second connecting rod 506, and the L-shaped frame 501 is used to limit the limiting sleeve 507. When the second connecting rod 506 moves downward and rotates, it is elastically supported by the second spring 508, and when the mechanical claw arm 2 6 rotates, the limiting sleeve 507 slides inside the L-shaped frame 501, and the mechanical claw arm 1 2 can drive the second protective mechanism 5 to rotate around the base 1, thereby adapting to the rotation of the mechanical claw arm 2 6.

[0049] The working principle of this embodiment is as follows: when using this new energy vehicle chassis maintenance manipulator, the slot block 402 is engaged with the rotating block 401 and pushed to make them flush. The slot block 402 squeezes the spherical column 406 to compress the first spring 407, causing the spherical column 406 to move inside the rotating block 401. When the rotating block 401 is flush with the side of the slot block 402, the spherical column 406 is pushed by the first spring 407 to engage with the hemispherical hole 403, thereby positioning the rotating block 401 and the slot block 402. At this time, the internal threads of the rotating block 401 and the slot block 402 are screwed into the threaded rod 408, and the nut 409 is screwed on the other side, and the positioning and fixation of the rotating block 401 and the slot block 402 are achieved by reverse setting in sequence, thereby achieving the limitation and fixation of different clamping claws. When the chassis of the source car is being repaired, the mechanical claw arm 26 pushes the rotating shaft seat 504 to move and rotate, thereby driving the second connecting rod 506 to move downward. At this time, the second connecting rod 506 is elastically supported by the limiting sleeve 507 and the second spring 508, which can play a role of buffering and shock absorption when the mechanical claw arm 26 is subjected to force, absorb part of the impact force, and reduce the vibration caused by sudden changes in external force. While the mechanical claw arm 1 rotates on the upper surface of the base 1, the arc hole of the L-shaped frame 501 cooperates with the rotating frame 502 and the auxiliary wheel 503, so that the second connecting rod 506 can adapt to the rotation and angle changes of the mechanical claw arm 12 and the mechanical claw arm 26, ensuring that appropriate support and buffering can be provided in different postures, making the movement of the mechanical claw arm 12 and the mechanical claw arm 26 more stable, thereby eliminating the problem of vibration or unstable grasping of the mechanical claw arm 12 and the mechanical claw arm 26.
