Description

Technical Field

[0001] The present application relates to the field of speed measurement modules, and in particular to a dual-path automatic correction speed measurement module. Background Art

[0002] The dual-channel automatic correction speed measurement module is a device used to accurately measure and control speed. It is usually used in automated equipment such as smart cars and robots to achieve precise speed control and navigation. This module has two signal output channels and can simultaneously measure two different speed parameters. It automatically corrects through a built-in algorithm to ensure the accuracy and stability of speed measurement. The dual-channel speed measurement module is usually used in conjunction with a code disk to calculate the speed by measuring the rotation of the code disk. The code disk is a symmetrically distributed light-transmitting hole device used to improve the accuracy and reliability of speed measurement. When installing the speed measurement module, several connectors are installed on one end of the detection module. The surface of the connector is snapped into the installation slot in the docking connector, and one end of the docking connector is connected to other devices with the help of a connecting line.

[0003] With regard to the above-mentioned related technologies, the inventors believe that when a conventional speed measurement module is installed, the connector used is generally connected by several bonding materials. When the connector is squeezed by external force or bent due to inaccurate docking, it is easy to cause damage to the connector when it is installed with the docking head.

[0020] The following is combined with Figure 1 —4 Provide further details of this application.

[0021] The embodiment of the present application discloses a dual-path automatic correction speed measurement module, referring to Figure 1 - Figure 2 , including a detection module 1. During installation, several connectors 2 are installed on one end of the detection module 1. The surface of the connector 2 is snapped into the mounting groove 4 in the docking joint 3. One end of the docking joint 3 is connected to other equipment with the help of a connecting line 5. The mounting bracket 6 is connected to the top of the detection module 1. A connecting groove 7 is provided on the inner wall of the mounting bracket 6. The inner wall of the connecting groove 7 is snapped into the surface of the docking joint 3. The surface of the connector 2 is shielded by the mounting bracket 6, which effectively improves the protection effect of the connector 2 in the speed measurement module. The structure is simple and easy to operate, avoiding the situation where the connector 2 is squeezed by external force and bent. The inner wall of the connecting groove 7 is snapped into the surface of the docking joint 3, which facilitates the installation of the connector 2 and the docking joint 3, avoiding the situation where the connector 2 is bent due to force caused by deviation when the docking joint 3 is installed with the connector 2.
