Description

Technical Field

[0001] The present invention relates to the technical field of robots, and particularly to a robot docking connector. Background Art

[0002] A robot refers to a robot system, which usually consists of two wheels or a wheel assembly composed of wheels. This design enables the robot to move on a horizontal surface and can achieve steering and rotation by controlling the speeds of different wheels. A two-wheel robot usually uses a differential drive system. By independently controlling the speed of each wheel, various movements such as forward, backward, and turning of the robot can be achieved. In addition, a two-wheel robot can also achieve rotational movement by controlling the speed difference between the wheels, which makes them very flexible and suitable for narrow spaces and complex environments.

[0003] In the existing robots during use, there is no structure for automatically docking and transmitting data between two robots. Currently, when it is necessary to connect two robots, it is all done manually by using a data cable for connection and transmission, which is relatively cumbersome and inconvenient to use. Therefore, it is necessary to address the connection of existing robots. Summary of the Invention

The ratchet seat 32 is arranged in the ratchet groove 122. The ratchet seat 32 is provided with a hinge groove 321 for hinging the ratchet pawl 33. One end of the tension element 31 is connected to the ratchet pawl 33 to provide a hinge tension for the ratchet pawl 33. The ratchet tooth seat 34 is arranged on the docking plug 21. The ratchet tooth seat 34 is provided with a tooth groove 341 to cooperate with the ratchet pawl 33. This embodiment is used for robots to dock and transmit data, power connection, etc. The ratchet connection mechanism 3 is provided to play a role of preventing the plug from retracting when the docking female seat 1 and the docking male seat 2 are connected. When the docking plug 21 is inserted into the plugging cavity 121, the ratchet pawl 33 cooperates with the ratchet groove 122, and the docking plug 21 will not move backward. It is not until it is inserted to the innermost part that the ratchet pawl 33 is pulled back to the original position by the tension element 31 before it can be retracted and loosened. This makes the stability better during the ratchet insertion process, and there will be no backward movement phenomenon during the insertion process. It solves the problem of the easy backward movement phenomenon in the existing docking process.

[0035] In this embodiment, the docking plug 21 is inserted into the plug cavity 121 of the docking sleeve 12, thereby realizing a reliable conductive connection between the head seat power connection component 22 and the female seat power connection component 13, thereby ensuring the stability of the connector and the reliability of electrical transmission. A ratchet connection mechanism 3 is adopted, and the design of the ratchet seat 32, the pawl 33 and the ratchet seat 34 realizes the flexible plugging and fixing of the connector, making the connection operation more convenient and reliable.

The connector has a stable structure and is not easy to loosen or disconnect during the plugging and unplugging process, which is conducive to ensuring the safe use of the connector and reducing the risk of accidental disconnection.

[0036] The docking sleeve 12 is provided with a connecting platform 123, one side of which is connected to the mother base plate 11, and a connecting element 124 is provided on the side of the connecting platform 123 which is opposite to the mother base plate 11, and one end of the tension element 31 is connected to the connecting element 124, and the other end is connected to the pawl 33. In this embodiment, the connecting platform 123 is used to cooperate with the installation and connection of the mother base plate 11, and the structure is easy to assemble. The design of the connecting element 124 facilitates the connection and fixation of the tension element 31. The tension element 31 of this embodiment is used with an axial structural member or a screw, the purpose of which is to fix the two ends of the tension spring to ensure the tension stability of the pawl 33 during the articulation activity.

[0037] A guiding bevel 125 is provided at the port of the docking sleeve 12, and the guiding bevel 125 expands outwards.

Specifically, a limiting step 126 is provided on the side of the plug-in cavity 121 close to the guiding bevel 125, and the docking plug 21 is provided with a stop plug step 212. When the docking plug 21 is inserted into the plug-in cavity 121, the limiting step 126 is used to cooperate with the stop plug step 212 to stop the plug-in. In this embodiment, the design of the guiding bevel 125 and the guiding bevel 211 enables the docking plug 21 to be accurately guided toward the plug-in cavity 121 when it is inserted, ensuring the accuracy and stability of the plug-in and reducing the error rate. Through the matching design of the limit step 126 and the stop plug step 212, the butt plug 21 is reliably stopped when inserted into the plug cavity 121, which prevents over-insertion or falling off during the plugging process, and enhances the reliability and stability of the connector. The precise plugging guide and reliable plugging limit design help reduce friction and collision between connecting parts, extend the service life of the connector, and reduce wear and damage to parts. The optimized plugging guide design makes the plugging and unplugging operation of the connector smoother and more convenient, reducing the difficulty of operation.

The tension connection end 332 is used to connect the tension element 31, and the ratchet connection end 333 is used to cooperate with the tooth groove 341. In this embodiment, through the design of the hinge shaft 331 and the hinge positioning groove, the stable hinge connection between the pawl 33 and the ratchet connection end 333 is realized, ensuring the reliability and stability of the connection. The tension spring is connected to the tension connection end 332 of the pawl 33, which can provide stable tension transmission, ensuring the stable movement and force transmission of the pawl 33 during operation. The stable hinge connection and tension transmission design help to enhance the overall reliability and stability of the connector, ensuring the stable connection and transmission quality of the connector during long-term use.

[0040] An included angle is formed between the tension connection end 332 and the ratchet connection end 333.

In this embodiment, the direction movement mechanism 4 is arranged on the female base substrate 11, which can provide a direction floating force for the female base substrate 11, enabling the connector to more flexibly adapt to the plugging operations in different directions during the connection process, improving the applicable range and flexibility of the connector. Through the connection between the movable substrate 41 and the movable guide rail 42, a stable connection between the direction movement mechanism 4 and the female base substrate 11 is realized, ensuring the stability and reliability of the connector during use. The movable tension assembly 43 adopts a movable tension spring 431, which is connected to the movable substrate 41 and the female base substrate 11 through the tension shafts 432, and can provide a stable tension transmission, ensuring the stable movement and force transmission of the direction movement mechanism 4. The design of the direction movement mechanism 4 enables the connector to better adapt to the plugging requirements at various different angles and directions, improving the versatility and adaptability of the connector. Specifically, two groups of the movable tension assemblies 43 are arranged, and the positions and directions of the tension shafts 432 of the two groups are opposite (on one side, the two tension shafts 432 are on the movable substrate 41 and the female base substrate 11, and on the other side, the two tension shafts 432 are on the female base substrate 11 and the movable substrate 41). The purpose is to generate opposite tensions on both sides, so as to keep the female base substrate 11 in the center. When floating is required, it can slide along the movable guide rail 42.
