One end of the connecting hole 24 passes through the connecting body 2, facilitating the smooth passage of the connecting rod 4 and providing a basis for the subsequent installation of additional structures such as cameras and handles. This not only enhances the robot's functionality but also allows for flexible configuration adjustments based on actual needs, meeting the requirements of diverse application scenarios. The flexible connection method, reliable performance, and excellent expandability of this embodiment provide an efficient and convenient solution for connecting the robot body. Whether from the perspective of improving the overall performance of the robot or meeting the needs of diverse application scenarios, this connecting mechanism demonstrates extremely high application value and development potential.
[0027] In different embodiments, the connecting mechanism can be used to mount structures such as cameras and handles to expand its applications.
[0028] In another embodiment, the connecting mechanism is a grip connecting mechanism, which includes a fixed base 1, a connecting body 2, a cam handle 3, a connecting rod 4, and a connector 5. The connecting body 2 includes a connecting part 21, an operating part 22, and a gripping part 23. The connecting part 21 is located below the operating part 22, and the gripping part 23 is disposed on one side of the operating part 22. The operating part 22 is provided with a connecting hole 24, one end of which extends through to the connecting part 21. One end of the connecting rod 4 passes through the connecting hole 24 and connects to the connector 5. The cam handle 3 is disposed at one end of the connecting rod 4, and the connector 5 is disposed on the fixed base 1. The cam handle 3 is used to drive the connecting rod 4 so that the connector 5 cooperates with the connecting part 21 to be fixed on the fixed base 1. In this embodiment, the grip connecting mechanism is used for robot gripping and transfer. It is stably connected to the wheeled robot body through the fixed base 1, ensuring stability and reliability during operation. The design of the connecting body 2 conforms to ergonomic principles. The rational layout of the connecting part 21, operating part 22, and gripping part 23 allows operators to easily grip and apply force when controlling the robot, thereby improving operational accuracy and comfort. Secondly, the cam handle 3 greatly simplifies the robot's control process. Operators only need to rotate the cam handle 3 to drive the connecting rod 4, which in turn causes the connecting piece 5 to tightly engage with the connecting part 21, achieving quick fixing and unlocking of the grip and the robot body. This design not only improves operational efficiency but also reduces the risk of misoperation. The connection structure between the components is clear and easy to disassemble. When maintenance or repair of the robot is required, operators can quickly disassemble the grip connection mechanism without using complex tools or spending excessive time. The application of this embodiment in a wheeled robot also demonstrates good adaptability and scalability. By adjusting the design of the connecting piece 5 and the fixed base 1, it can be easily applied to different types of wheeled robots to meet diverse application scenarios and needs, while also improving the robot's operational performance and maintenance efficiency.
[0029] A fixed groove 11 is provided on the fixed base 1, and the connector 5 is movably mounted on the fixed groove 11. One end of the connecting rod 4 passes through the fixed groove 11 and connects to the connector 5. In this embodiment, the fixed groove 11 allows the connector 5 to be flexibly mounted on it. This design not only enhances the flexibility and adaptability of the grip connection but also ensures the stability and reliability of the connection. One end of the connecting rod 4 passes through the fixed groove 11 and is tightly connected to the connector 5. This connection method not only simplifies the installation steps and improves assembly efficiency but also effectively distributes the force and enhances the load-bearing capacity of the entire connection structure. In practical applications, this structure allows the grip to be quickly and easily adjusted according to different usage needs, thereby improving the ease of operation and user experience of the device. At the same time, due to the tight fit between the connector 5 and the fixed groove 11, it also effectively prevents the grip from loosening or falling off during use, further improving the safety and stability of the device. The connector 5 can slide into the fixed groove 11 through both ends of the fixed base 1; alternatively, the connector 5 can be rectangular, and the fixed groove 11 has an opening facing the connecting rod 4, the width of which is smaller than the width of the fixed groove 11. During assembly, the connector 5 is first placed into the fixed groove 11 through the opening, and then rotated 90 degrees to limit its movement within the fixed groove 11. The installation process is as follows: The handle and fixed base 1 form a 90-degree angle; the connector 5 is placed into the fixed base 1 for limitation; then rotated 90 degrees to make the handle parallel to the fixed base 1; finally, the cam handle 2 is pressed down to tighten it, locking the connector 5 onto the fixed groove 11.
[0030] In the above embodiments, the fixed base 1 can be the robot body, or it can be an extension plate, slide rail, or other structures. Specifically, a fixed groove 11 can be provided to accommodate the assembly of the connector 5.
[0031] The connecting part 21 is provided with a connecting locking surface 211, which is used to mate with the surface of the fixed base 1. A positioning boss 212 is provided on the connecting locking surface 211, which is used to mate with the groove of the fixing pull groove 1111 to position the connecting locking surface 211. A chamfer 213 is provided on one side of the positioning boss 212. Specifically, the connecting locking surface 211 of the connecting part 21, through its tight fit with the surface of the fixed base 1, ensures a stable and reliable connection between the handle and the fixed base 1, effectively improving the stability and durability of the overall structure. The carefully designed positioning boss 212 on the connecting locking surface 211 precisely mates with the groove of the fixing pull groove 1111, which not only simplifies the installation process but also achieves precise positioning of the connecting locking surface 211, avoiding loosening or misalignment caused by improper installation. In addition, the chamfer 213 on one side of the positioning boss 212 further optimizes the assembly process, so that the positioning boss 212 can be smoothly guided into the fixing groove 1111 during the installation process, reducing the assembly difficulty and improving work efficiency.
[0032] A gripping slot 214 is provided on the side of the connecting part 21 near the operating part 22. A connecting post 215 is provided between the gripping slot 214 and the gripping part 23, and a connecting hole 24 is provided on the connecting post 215. In this embodiment, the gripping slot 214 provided on the side of the connecting part 21 near the operating part 22 not only reduces the weight of the entire mechanism, but also provides users with a more comfortable gripping experience, reducing hand fatigue during prolonged use. Secondly, the gripping slot 214 and the gripping part 23 are connected by the connecting post 215. This design ensures the stability of the structure and allows the gripping part 23 to evenly distribute pressure when subjected to force, improving overall durability. In addition, the connecting hole 24 is located on the connecting post 215. This detail design facilitates quick and accurate connection with other components, greatly simplifying the installation and disassembly process and improving work efficiency. At the same time, the position of the connecting hole 24 can meet the connection needs of different application scenarios, increasing the versatility and flexibility of the grip connection mechanism.
[0033] The operating part 22 is provided with a quick-release groove 221, and the cam handle 3 is disposed within the quick-release groove 221. A countersunk groove 222 is provided on the quick-release groove 221, and a retaining ring 223 is provided on the countersunk groove 222. One end of the countersunk groove 222 communicates with the connecting hole 24, and the retaining ring 223 is disposed on the connecting rod 4. In this embodiment, the design of the quick-release groove 221 allows the cam handle 3 to be quickly and securely installed, greatly improving the assembly efficiency and convenience of the grip connection mechanism. Simultaneously, the introduction of the countersunk groove 222 further enhances the stability of the structure, effectively preventing loosening or displacement of the cam handle 3 during use by providing an additional support surface. The retaining ring 223 is mounted on the connecting rod 4 and, through its cooperation with the countersunk groove 222, achieves a secure lock on the cam handle 3. This locking mechanism not only ensures the reliability of the grip connection mechanism but also allows the user to quickly and easily disassemble the cam handle 3 when needed, thereby meeting different usage requirements.
[0034] The cam handle 3 includes a handle portion 31 and a cam portion 32. The handle portion 31 is located on one side of the cam portion 32, and the cam portion 32 is provided with a hinge shaft 33. The cam portion 32 is connected to the connecting rod 4 via the hinge shaft 33. The outer periphery of the cam portion 32 abuts against the fixing ring 223. Specifically, the fixing ring 223 is provided with a spherical groove 2231, which abuts against the outer diameter of the cam portion 32. In this embodiment, the cam handle 3 is ingeniously designed, consisting of a handle portion 31 and a cam portion 32. The handle portion 31 is located on one side of the cam portion 32, making it convenient for the user to grip and operate. The cam portion 32 is connected to the connecting rod 4 via the hinge shaft 33, achieving a flexible rotational connection and ensuring the stability and reliability of the handle at different angles. Most importantly, the outer periphery of the cam portion 32 abuts tightly against the spherical groove 2231 on the fixing ring 223. This design not only enhances the structural stability but also effectively reduces friction and wear on the cam portion 32 during rotation through the adaptability of the spherical groove 2231, thus extending its service life. Furthermore, the spherical groove 2231 also provides the cam portion 32 with a certain degree of floating capability, allowing it to better adapt to the minute displacements of the connecting rod 4 under different working conditions, thereby improving the flexibility and adaptability of the entire grip connection mechanism.
[0035] The connecting rod 4 includes a fixed rod 41, a locking rod 42, and an elastic element 43. One end of the fixed rod 41 is connected to the cam handle 3, and the other end is connected to the locking rod 42. One end of the locking rod 42 is connected to the connector 5. The elastic element 43 is sleeved on the outside of the fixed rod 41. A locking step 241 is provided on the connecting hole 24. One end of the elastic element 43 abuts against the locking step 241, and the other end abuts against the locking rod 42. Specifically, the connector 5 has fixed steps 51 on both sides, and the fixed seat 1 has a fixed groove 1111. A locking strip 111 is provided at the opening of the fixed groove 1111. The fixed step 51 is used to cooperate with the locking strip 111 so that the connecting part 21 is fixed on the fixed seat 1. In this embodiment, the precise connection between the fixed pull rod 41, the cam handle 3, and the locking pull rod 42 achieves a stable connection between the grip and the connecting part 21, enhancing the stability and reliability of the overall structure. Furthermore, the fixed steps 51 on both sides of the connecting part 5 cooperate with the fixed grooves 1111 and the locking strips 111 on the fixed seat 1 to form a highly efficient locking mechanism. This design not only simplifies the installation process but also significantly improves the fixing effect of the connecting part 21, effectively preventing loosening or detachment of the connecting part 21 during long-term use.
[0036] In one embodiment, the locking lever 42 is a hexagonal prism. The hexagonal prism engages with the connecting hole 24 to prevent rotation of the hexagonal prism / nut. In this embodiment, the hexagonal prism is used to prevent rotation by engaging with the connecting hole 24 between the fixing seat 1 and the handle. In different embodiments, rotation can also be prevented using a key and groove, a pair of smooth rods and linear bearings, a dedicated guide rail, etc.
[0037] The elastic element 43 is a spring, which is used to keep the quick-release handle vertical to prevent wobbling and improve the user experience.
[0038] A robot includes the aforementioned grip connection mechanism. The robot includes a body, and the grip connection mechanism is disposed on the body. In this embodiment, the robot facilitates gripping and transfer after the grip connection mechanism is engaged.
[0039] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent.
