[0065] Embodiment 1

[0066] In view of the defects of the above-mentioned prior art, the applicant, based on many years of rich practical experience and professional knowledge in the design and manufacture of such products, and in conjunction with the application of theory, actively conducts research and innovation in the hope of creating a technology that can solve the defects of the prior art. After continuous research and design, and after repeated trial samples and improvements, the present utility model with real practical value was finally created.

[0067] Please refer to Figure 1-8 The embodiment of the utility model provides a non-contact encoder, including a rotating component 1 and a magnetic induction component 2; wherein,

[0068] The rotating assembly 1 comprises a fixed portion 11 and a rotating portion 12, wherein the rotating portion 12 is connected to the fixed portion 11 so as to be relatively rotatable;

[0069] The magnetic induction component 2 includes a trigger element 21 and two sensor elements 22;

[0070] The two sensor elements 22 are disposed at intervals on the fixed portion 11 , and the trigger element 21 is disposed on the rotating portion 12 and located between the two sensor elements 22 ;

[0071] When the rotating part 12 rotates under the action of an external driving force, the trigger element 21 disposed thereon will also rotate accordingly. Since the trigger element 21 is located between the two sensing elements 22, when it rotates and passes through the two sensing elements 22 in sequence, it will trigger the two sensing elements 22 in sequence to generate sensing signals. The two sensing signals can be processed by a circuit, for example, converted into a digital signal or a pulse signal, so as to accurately reflect the rotation angle or position of the rotating part 12.

[0072] It should be noted that this embodiment has the following advantages and features:

[0073] Stable signal: Due to the use of magnetic induction principle, the induction signal is stable and not easily affected by external interference.

[0074] Long life: The non-contact design avoids mechanical wear and greatly extends the service life of the encoder.

[0075] Waterproof and moisture-proof: The non-contact design is also conducive to waterproof and moisture-proof, suitable for harsh environments.

[0076] High precision: By accurately designing the relative position and distance between the trigger element 21 and the sensor element 22, high-precision angle or position detection can be achieved.

[0077] In this embodiment, optionally, the trigger element 21 is a magnet.

[0078] The sensor element 22 is a Hall IC.

[0079] It should be noted that, in this embodiment, a magnet is specially selected as the trigger element 21 , and a Hall IC (Hall Integrated Circuit) is selected as the sensor element 22 .

[0080] The magnet is used as the trigger element 21, and its stable magnetic field characteristics can ensure reliable interaction with the sensor element 22. When the rotating part 12 drives the magnet to rotate, the magnetic field of the magnet will pass through two Hall ICs (sensing elements 22) arranged at intervals in sequence. The Hall IC can sense the changes in the magnetic field and generate corresponding induction signals.

[0081] Please refer again Figure 4-6 , which shows in detail the important components of the fixing portion 11 in this embodiment.

[0082] The fixing part 11 not only supports the stability of the overall structure of the encoder, but also provides a foundation for the installation and fixing of other components. The fixing part 11 is mainly composed of a fixing seat 111 and a PCB (printed circuit board) 112.

[0083] The fixing base 111 and the PCB 112 are connected in a detachable manner. This design not only facilitates the assembly and maintenance of the encoder, but also improves the flexibility of the overall structure. When the PCB 112 needs to be replaced or repaired, it can be easily removed from the fixing base 111, which greatly saves maintenance time and cost.

[0084] On the PCB 112, two sensing elements 22 are precisely spaced apart. A stable electrical connection is established between the two sensing elements 22 and the PCB 112, ensuring accurate transmission of the sensing signal. The precise position and stable connection of the sensing elements 22 are crucial for high-precision detection of the encoder.

[0085] In addition, the fixing portion 11 of this embodiment is also equipped with an output line. This output line is also electrically connected to the PCB 112, and is used to transmit the sensing signal generated by the sensor element 22 to an external device or system. The introduction of the output line further enhances the practicality and convenience of the encoder, allowing the user to more conveniently obtain and process the detection data of the encoder.

[0086] Please refer again Figure 3 and 5 In this embodiment, the specific design of the rotating part 12 of the contactless encoder and the trigger element 21 is discussed in depth. These design details not only reflect the sophistication of the technology, but also ensure the stability and reliability of the encoder in practical applications.

[0087] As an important component of the encoder, the rotating part 12 has a unique and delicate design and comprises a rotating outer ring 121 and a rotating shaft 122, which cooperate with each other to achieve high-precision rotation detection of the encoder.

[0088] The rotating outer ring 121 is the main rotating part, and the fixing seat 111 is arranged inside the rotating outer ring 121. This design enables the fixing seat 111 to be stably located inside the rotating outer ring 121, providing a stable support for the entire encoder.

[0089] The rotating shaft 122 is a key component for rotating the outer ring 121 to drive the trigger element 21 to rotate, and one end of the rotating shaft 122 is firmly fixed to the fixing seat 111. This connection method ensures that the rotating shaft 122 can maintain a stable connection with the fixing seat 111 during the rotation process, thereby achieving stability and reliability of rotation.

[0090] In order to further improve the accuracy and stability of rotation, a gear ring is designed on the inner ring surface of the rotating outer ring 121. This gear ring meshes with the side wall of the rotating shaft 122, and through the precise matching between the teeth, accurate control and stable transmission of rotation are achieved. This design not only improves the accuracy of rotation, but also extends the service life of the encoder.

[0091] In this embodiment, the trigger element 21 is cleverly arranged on the side wall of the rotating shaft 122. When the rotating shaft 122 rotates with the rotating outer ring 121, the trigger element 21 will also move, thereby causing relative displacement with the sensor element 22, triggering it to generate a sensing signal. This design ensures the accuracy and stability of the sensing signal, providing a strong guarantee for the high-precision detection of the encoder.

[0092] Please refer again Figure 3 , 5 and 7, in this embodiment, the rotating outer ring member 121 includes a rotating bracket 1211 and a rotating cover 1212;

[0093] The fixing seat 111 is disposed inside the rotating bracket 1211;

[0094] The gear ring is provided on the inner annular surface of the rotating bracket 1211;

[0095] The rotating cover 1212 is sleeved on the rotating bracket 1211 and can drive the rotating bracket 1211 to rotate.

[0096] It should be noted that the rotating bracket 1211 is not only the main structure of the rotating outer ring 121, but also the basis for the encoder to realize the rotation detection function. The rotating cover 1212 is another important component of the rotating outer ring 121. It is cleverly mounted on the rotating bracket 1211, and the user can drive the rotating bracket 1211 to rotate by operating the rotating cover 1212. This design makes the operation of the encoder more convenient and intuitive, and also enhances the aesthetics and practicality of the encoder.

[0097] Please refer again Figure 8 In this embodiment, the rotary cover 1212 includes a rotary ring 12121, a decorative ring 12122 and a panel 12123;

[0098] The rotating ring 12121 is provided with a circle of buckling grooves, and the decorative ring 12122 is correspondingly provided with buckling protrusions that can be buckled in the buckling grooves;

[0099] The panel 12123 is disposed inside the decorative ring 12122 and is detachably connected to the fixing seat 111;

[0100] Alternatively, the panel 12123 is covered on the decorative ring 12122 .

[0101] It should be noted that the rotary cover 1212, as a component of the rotating outer ring 121, is not only beautiful in design but also highly functional, ensuring the stability and operability of the encoder.

[0102] The rotary cover 1212 is composed of three main parts: a rotary ring 12121, a decorative ring 12122 and a panel 12123. This modular design not only enables each part of the rotary cover to be maintained and replaced separately, but also greatly enhances the customizability and personalization of the entire encoder.

[0103] The design of the decorative ring 12122 reflects the exquisiteness and taste of the encoder in appearance. The decorative ring 12122 is provided with a snap-fitting protrusion that can be snapped into the snap-fitting slot of the rotating ring 12121. This design not only ensures the integrity and aesthetics of the appearance of the rotating cover, but also greatly enhances the connection stability between the rotating cover and the rotating bracket 1211.

[0104] The panel 12123 is provided to improve the functionality of the rotary cover 1212. The panel 12123 can be located inside the decorative ring 12122 and connected to the fixing seat 111 in a detachable manner. This design not only facilitates the replacement and maintenance of the panel, but also provides users with customized options. For example, users can choose panels of different materials, colors and patterns as needed to meet different application scenarios and personalized needs.

[0105] In addition, the panel 12123 can also be designed to be covered on the decorative ring 12122. This design makes the rotary cover more concise and elegant in appearance, and also enhances the connection stability between the rotary cover and the rotating bracket 1211.

[0106] In this embodiment, the fixing base 111 and the PCB 112 are detachably connected by snapping.

[0107] It should be noted that the connection between the fixing base 111 and the PCB 112 adopts a snap-fit ​​method to achieve a detachable connection between the two. This design not only ensures the stable installation of the PCB 112 inside the encoder, but also makes the replacement and maintenance of the PCB 112 simple and convenient. Through the snap-fit ​​connection, the PCB 112 can be easily removed and installed without using additional tools or complicated operating steps.

[0108] In this embodiment, the panel 12123 and the fixing base 111 are detachably connected by snapping.

[0109] It should be noted that a snap-fit ​​connection is also used between the panel 12123 and the fixing seat 111. This design makes the connection between the panel 12123 and the fixing seat 111 tighter and more stable. Through the snap-fit ​​connection, the panel 12123 can fit tightly on the fixing seat 111 to form a whole, which enhances the overall appearance and durability of the encoder. At the same time, this connection method also makes the replacement and maintenance of the panel 12123 simple and convenient, and the user can easily disassemble and install the panel 12123 to meet different usage requirements.

[0110] Although the terms such as rotating component, magnetic induction component, fixed part, etc. are used more frequently in this application, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.

[0111] The utility model provides a non-contact encoder, which adopts a trigger element and two sensor elements to form a magnetic induction component, so that when the trigger element rotates relative to the two sensor elements under the drive of the rotating part of the rotating component, the trigger element will pass through the two sensor elements in sequence, thereby triggering the two sensor elements to generate an induction signal. Not only is the signal stable, but the non-contact type also avoids the influence of mechanical wear and has a longer service life. It is also conducive to waterproof and moisture-proof design, and is suitable for large-scale promotion and application.
