[0027] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] like Figures 1 to 6As shown, an embodiment of the present invention provides a mobile chassis 100, comprising a chassis body 1 and a driving device 2, wherein the driving device 2 is provided on the chassis body 1 and is used to drive the chassis body 1 to move along a preset direction;

[0029] Mounting frames 4 and counterweights 7 are provided on either side of the chassis body 1. The top surface of the mounting frame 3 forms a first mounting surface for mounting the lifting drive body 200. In this embodiment, a drive device 2 is provided on the chassis body 1 and, by receiving external commands or signals, can drive the chassis body 1 to move in a predetermined direction. This movement can be linear or curved. The lifting drive body 200, through its internal transmission mechanism and power source, can achieve lifting and lowering control of the upper lifting arm 300. When materials need to be transported, the lifting drive body 200 drives the upper lifting arm 300 to move in the vertical direction to complete the material transportation. The mobile chassis body 1 achieves a compact structure by integrating components such as the drive device 2, the mounting frame 4, and the counterweight 7. This design not only reduces the size and weight of the chassis but also improves its ease of operation. Although the provision of the counterweight 7 increases the weight of the chassis to a certain extent, more importantly, it optimizes the center of gravity of the chassis body 1, making the chassis more stable during movement. At the same time, by optimizing the structural design and other methods, the overall weight of the chassis is further reduced, improving its portability and flexibility. The modular design of the various components of the mobile chassis 100 makes disassembly and assembly easier. This design not only facilitates maintenance and upkeep of the equipment, but also improves its scalability and upgradeability. When a component needs to be replaced or upgraded, it can simply be removed from the chassis and replaced with a new one. By optimizing the structure and design of the chassis body 1, the mobile chassis 100 can carry materials of greater weight and volume.

[0030] In one embodiment, the chassis body 100 is provided with a second mounting surface 3 for mounting the upper mounting arm 300, the second mounting surface 3 being lower than the first mounting surface. In this embodiment, mounting the upper mounting arm 300 on the lower second mounting surface 3 helps lower the center of gravity of the entire device, reducing the risk of swaying or tipping caused by an excessively high center of gravity during travel or operation, and maintaining a stable travel posture. The lower second mounting surface 3 brings the center of gravity of the upper mounting arm 300 and the materials or equipment it carries closer to the ground, thereby increasing the lifting space of the upper mounting arm 300. When the docking height of the equipment docking with the upper mounting arm 300 is constant, the upper mounting arm 300 has a larger lifting space, thereby increasing the transport capacity of the mobile chassis 100 and improving the carrying capacity of the entire device. The layered installation (with the lifting drive body 200 on top and the upper mounting arm 300 on the bottom) allows for more efficient utilization of the internal space of the device, enabling the loading of more materials or equipment, thereby improving the loading capacity and operating efficiency of the device.

[0031] In one embodiment, the first mounting surface and the second mounting surface 3 are arranged sequentially along the front-to-back direction of the mobile chassis 1, with the first mounting surface being parallel to the second mounting surface 3. In this embodiment, the parallel arrangement of the first mounting surface and the second mounting surface 3 helps maintain the stability of the center of gravity of the device, allowing the device to maintain a stable walking posture regardless of whether on flat ground or rugged terrain, thereby improving safety and reliability. The arrangement of the first mounting surface and the second mounting surface 3 being arranged sequentially along the front-to-back direction of the mobile chassis 100 and maintained parallel in the vertical direction achieves the goal of loading more and walking more steadily by maximizing space utilization, improving loading efficiency, enhancing operational flexibility, maintaining a stable center of gravity, and improving controllability.

[0032] In one embodiment, the mobile chassis 100 also includes a laser radar 8, which is arranged on the chassis body 1 and on one side of the counterweight. In this embodiment, the laser radar 8 can help the mobile chassis 100 perceive the road environment and plan the driving route. The laser radar 8 is not arranged directly above the drive device 2, so that the installation height of the laser radar 8 is not affected by the structure of the drive device 2. The laser radar 8 can be installed at a lower position on the chassis body 1, so that the scanning surface of the radar and the height of the entire vehicle are not restricted and can be lowered accordingly, so that the mobile chassis 100 can adapt to more narrow spaces, while also avoiding the safety hazard caused by the laser radar 8 being too high in the scanning height. The mobile chassis 100 has two laser radars 8, the chassis body 1 is square, and the two laser radars 8 are respectively located at two diagonal corners of the chassis body 1.

[0033] In one embodiment, the drive device 2 includes a drive member 21 and a drive wheel 22. The drive wheel 22 is rotatably mounted on the chassis body 1. The drive member 21 is mounted on the chassis body 1. The output end of the drive member 21 is connected to the drive wheel 22 to drive the drive wheel 22 to rotate. In this embodiment, the drive member 21 can drive the drive wheel 22 to rotate, thereby driving the chassis body 1 to move. The drive member 21 can be a motor or other structure.

[0034] In one embodiment, the drive device 2 further includes a first auxiliary wheel 23 and a bracket 24. The bracket 24 extends in the second direction. The drive wheel 22 and the first auxiliary wheel 23 are respectively disposed at opposite ends of the bracket 24. The middle portion of the bracket 24 is rotatably connected to the chassis body 1, enabling the drive wheel 22 and the first auxiliary wheel 23 to move in opposite directions in the vertical direction. In this embodiment, a support rod is provided on the chassis body 1, and the bracket 24 is rotatably mounted on the support rod. The drive wheel 22 and the first auxiliary wheel 23 are respectively disposed at opposite ends of the bracket 24, forming a seesaw-like structure among the drive wheel 22, the first auxiliary wheel 23, the bracket 24, the support rod, and the chassis body 1. When the drive wheel 22 swings upward, the first auxiliary wheel 23 swings downward, and when the drive wheel 22 swings downward, the first auxiliary wheel 23 swings upward. When facing uneven roads, the drive wheel 22 and the first auxiliary wheel 23 can adapt to the terrain, and each wheel can maintain contact with the ground, providing effective driving force for the mobile chassis 100.

[0035] In one embodiment, the mobile chassis 100 further includes second auxiliary wheels 25 , which are mounted on the chassis body 1 . The drive device 2 and the second auxiliary wheels 25 are spaced apart along the front-to-back direction of the mobile chassis 100 . The second auxiliary wheels 25 are universal wheels, and there are two of them. These two second auxiliary wheels 25 are mounted on the front side of the chassis body 1 , which ensures more stable travel for the mobile chassis 100 .

[0036] In one embodiment, the mobile chassis 100 further includes a camera 12 for scanning the identification of an external device. The camera 12 is disposed on the chassis body 1. In this embodiment, the cameras 12 are disposed on the front, rear, left, right, and bottom sides of the chassis body 1. When docking with an external device, the camera 12 scans the identification of the external device to accurately confirm the location of the external device, thereby improving the docking accuracy between the mobile chassis 100 and the docking device.

[0037] According to the mobile chassis 100 provided in the embodiment of the present invention, traditional lifting equipment usually designs the lifting drive body 200 in the center of the chassis, which will cause the weight distribution of the entire chassis to be more concentrated, increasing the burden on the chassis. However, the present application sets the lifting drive body 200 on one side, which can make the weight distribution more uniform, thereby reducing the overall weight of the chassis (by moving the lifting drive body 200 to one side, the structure of the chassis can be designed more flexibly. For example, lightweight designs such as hollow sections and thin-walled structures can be adopted to further reduce the amount of material used, thereby reducing the weight of the chassis). After the weight is reduced, the flexibility and portability of the equipment will be improved. The design of the side-mounted drive body makes the chassis lighter when moving and installing, especially in a working environment where the equipment needs to be frequently moved. This design can greatly improve work efficiency. By setting a counterweight block 7 on the other side of the chassis, the weight of the lifting drive body 200 can be offset to achieve a balance in the center of gravity of the chassis. Installing the lifting drive body 200 on an easily accessible and operable mounting frame 4 simplifies the process of maintaining, upgrading or replacing various components. This modular design allows technicians to quickly complete the installation or disassembly of the lifting drive part 200 without the need for complex disassembly of the entire chassis, thereby reducing maintenance costs and improving work efficiency.

[0038] In addition, one embodiment of the present invention provides a panel assembly robot, comprising a lifting drive body 200, an upper attachment arm 300, and the mobile chassis 100 of the above-described embodiment. The lifting drive body 200 is mounted on a mounting frame 4, and the upper attachment arm 300 is mounted on the lifting drive body 200 and is capable of moving in the vertical direction. In this embodiment, the lifting drive body 200 is capable of driving the upper attachment arm 300 to perform reciprocating lifting motion. The driving structure may be composed of a cylinder, a slide rail, or the like, or may be composed of a motor, a driving wheel, a driven wheel, and a chain.

[0039] In one embodiment, the mobile chassis 100 further includes a battery 9 and an electronic control board 10. The battery 9 and the electronic control board 10 are located in the lift drive body 200, and the battery 9 and the drive device 2 are electrically connected to the electronic control board 10. By locating the battery 9 and the electronic control board 10 in the lift drive body 200, the number of components in the chassis body 1 is reduced, thereby simplifying assembly and maintenance of the components in the chassis body 1. The height of the chassis body 1 can be reduced, and the space for arranging the components on the chassis body 1 is increased, resulting in a more rational layout of the components in the chassis body 1 and more stable travel of the mobile chassis 100.

[0040] According to the panel assembly robot provided by the embodiment of the present invention, the close combination of the lifting drive body 200, the upper lifting arm 300 and the mobile chassis 100 makes the entire robot structure compact and convenient for operation in narrow spaces. Movement in the horizontal direction is achieved by the mobile chassis 100, and material handling and positioning in the vertical direction are completed by the lifting drive body 200 and the upper lifting arm 300. The side-mounted design of the lifting drive body 200 helps to optimize the overall weight distribution of the robot, reduce the burden on the chassis, make the robot more stable and safe when moving, and enable the robot to move and position more flexibly in space, thereby adapting to different working environments and task requirements.
