Description

Technical Field

[0001] The present application relates to the technical field of encoders, and in particular to an encoder with a new connection method. Background Art

[0002] Currently, encoders are connected through physical hard connections to complete power supply and communication, such as Figure 1 , Figure 1 The following is an encoder used in a motor, where the reference Figure 2 The encoder is installed in the rear cavity of the motor (or the encoder housing), and the encoder stator is connected to the encoder cable outside the encoder to realize power supply and communication of the encoder.

[0003] In actual applications, the encoder's internal connector may have poor contact due to factors such as the hard pulling of the thrown cable, or the internal cable may have poor contact due to the rotatability of the plug. Summary of the invention

[0004] The present application provides an encoder with a new connection method, which has the advantage that the static disk in the encoder realizes power supply and signal transmission through a wireless connection method, eliminating the cables connected to the static disk in the encoder, thereby overcoming the poor contact failure caused by the cables.

[0005] The above-mentioned object of the present application is achieved through the following technical solutions: an encoder with a new connection method, comprising a housing, an encoder moving disk and an encoder static disk arranged in the housing, a wiring terminal arranged on the outer side of the housing, the wiring terminal being used to connect the encoder cable, a first wireless charging module and a first short-distance transmission chip module arranged in the wiring terminal, and a second wireless charging module and a second short-distance transmission chip module arranged on the encoder static disk;

[0006] The first wireless charging module is used to supply power to the second wireless charging module, and the first short-distance transmission chip module and the second short-distance transmission chip module are connected by wireless communication.

[0007] Furthermore, the first wireless charging module includes a power transmission coil, and the second wireless charging module includes a power receiving coil, and the power transmission coil and the power receiving coil are coupled.

[0008] Furthermore, the first short-distance transmission chip module and the second short-distance transmission chip module communicate with each other using a carrier frequency band of 60 GHz. The first short-distance transmission chip module and the second short-distance transmission chip module are ST60 wireless connector modules.

[0009] Furthermore, the wiring terminal is provided with an aviation plug for connecting to an encoder cable.

[0010] Furthermore, the housing comprises an inner housing and an outer housing, the outer housing is rotatably arranged outside the inner housing, and the connection terminals are arranged on the outer housing.

[0011] In summary, the beneficial effects of this application are:

[0012] 1. This application can realize short-distance point-to-point contactless connection between the terminal block and the encoder static disk, get rid of the need for physical cables and connectors, eliminate the flexible cables in the equipment, and effectively solve the problems of easy corrosion, easy wear, high cost, poor contact, etc. in traditional contact connection;

[0013] 2. This application uses a short-distance transmission chip module such as ST60, based on the 60GHz radio frequency millimeter wave band, and its data transmission speed can far exceed the gigabit rate; this is unattainable by other current wireless communication technologies (such as Bluetooth and WiFi technologies);

[0014] 3. The wireless short-distance transmission solution provided by this application has ultra-low power consumption at the mW level, which is an order of magnitude that other current wireless communication technologies cannot achieve;

[0015] 4. The difficulty of developing a motor based on the encoder provided in this application is greatly reduced in terms of the waterproof and dustproof level of the motor;

[0016] 5. Based on the encoder provided in this application, the motor is developed. The encoder movable plug at the motor end, such as a rotatable aviation plug, can achieve 360-degree infinite rotation, breaking through the limitation of the rotation angle;

[0017] 6. Compared with the current Bluetooth or WiFi technology, millimeter wave transmission operates in the 60GHz radio frequency band, so its operation is not affected by cellular wireless communications, 5G, WiFi, Bluetooth and other signals. And because this solution is a low-power device and can only be transmitted over a short distance, the stray radiation will dissipate quickly and will not interfere with other devices.

[0022] The specific implementation of the present application is described in detail below with reference to the accompanying drawings.

[0023] Example: A new type of encoder connection, reference Figure 3 , including a shell 1, an encoder moving disk 2 and an encoder static disk 3 are arranged in the shell 1, a wiring terminal is arranged on the outside of the shell 1, the wiring terminal is used to connect the encoder cable, a first wireless charging module 5 and a first short-distance transmission chip module 6 are arranged in the wiring terminal, and a second wireless charging module 7 and a second short-distance transmission chip module 8 are arranged on the encoder static disk 3.

[0024] The first wireless charging module 5 is used to supply power to the second wireless charging module 7, and the first short-distance transmission chip module 6 and the second short-distance transmission chip module 8 are connected by wireless communication. The first wireless charging module 5 includes a power transmission coil, and the second wireless charging module 7 includes a power receiving coil, and the power transmission coil and the power receiving coil are coupled. The power transmission coil and the power receiving coil are arranged in parallel and opposite to each other. For example, when the terminal is installed in the radial direction of the housing 1, the power receiving coil is arranged to be parallel to the axial direction of the encoder; when the terminal is installed in the axial direction of the housing 1, the power receiving coil is arranged to be perpendicular to the axial direction of the encoder.

[0025] The first short-distance transmission chip module 6 and the second short-distance transmission chip module 8 communicate with each other using a carrier frequency band of 60 GHz. The first short-distance transmission chip module 6 and the second short-distance transmission chip module 8 are ST60 wireless connector modules. The ST60 wireless connector module is a high-data transmission, low-power, short-distance point-to-point physical transmission chip that does not require any protocol.

[0026] The wiring terminal is provided with an aviation plug for connecting to an encoder cable. The encoder cable includes a power line and a data communication line, which are respectively connected to the first wireless charging module 5 and the first short-distance transmission chip module 6.

[0027] In some other embodiments of the present application, the shell 1 includes an inner shell and an outer shell, the outer shell is rotatably arranged on the outside of the inner shell, and the wiring terminals are arranged on the outer shell. The above-mentioned wireless connection method is used so that there is no cable restriction inside the encoder, which is conducive to realizing the rotational connection between the outer shell and the inner shell. The outer shell and the wiring terminals can achieve 360° stepless rotation on the encoder. The internal size of the encoder is small, and even if the power transmitting coil and the power receiving coil are not facing each other due to the rotation of the outer shell, the charging power can meet the encoder requirements. Based on this scheme, three groups of power receiving coils in the encoder are arranged at 120° intervals, so that no matter what angle the outer shell is rotated to, the second wireless charging module has a higher charging power.

[0028] The above is only a preferred implementation of the present application. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present application, and these all fall within the scope of protection of the present application.
