Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of measurement technology, in particular to an angular displacement sensor device and a measuring system. STATE OF THE ART

[0002] The angular displacement sensor, also known as a rotary angular displacement sensor, is a type of displacement sensor. It utilizes a patented contact-based or non-contact design and significantly improves long-term reliability compared to conventional angular displacement measuring devices such as synchroanalyzers and potentiometers. Its unique design ensures measurement accuracy without the use of wear-prone moving parts such as slip rings, vanes, contact sliders, or brushes.

[0003] In general, conventional angular displacement sensors use a relatively complex external design for measuring small angles. However, they have a low IP rating and are therefore not suitable for use in harsh environments. Due to their split design, these sensors are often characterized by lower measurement accuracy, long adjustment cycles, and high costs. CONTENT OF THE PRESENT UTILITY MODELS

[0004] One of the purposes of the present application is to provide an angular displacement sensor device and a measuring system that achieves the technical effect of simplified construction and cost reduction.

[0005] In a first aspect, the present application provides an angular displacement sensor device comprising a main body, an induction board, and a rotor assembly;

[0006] The main body is provided with a rotor assembly receiving space, and the induction board is mounted inside the main body;

[0007] The rotor assembly comprises a rotor body and a magnet, wherein the rotor body is rotatably mounted in the rotor assembly receiving space, wherein the magnet is provided between the rotor body and the induction board and fixedly mounted at one end of the rotor body.

[0008] In the implementation process described above, the angular displacement sensor device enables the rotor body to be rotatably mounted directly in the rotor assembly receiving space by providing a rotor assembly receiving space on the main body. The mating assembly between the rotor body and the rotor assembly receiving space is simple and convenient. The magnet is provided between the rotor body and the induction board and is firmly mounted at one end of the rotor body close to the induction board. This simplifies the assembly structure and reduces manufacturing costs without compromising the measurement accuracy of the rotor assembly. Thus, the angular displacement sensor device can achieve the technical effect of simplified design and cost reduction.

[0009] The rotor assembly further includes a suspension member. One end of the suspension member is fixedly connected to the rotor assembly receiving space, and the other end of the suspension member is fixedly connected to the rotor body.

[0010] In the implementation process described above, the suspension part alternates between its natural state and its stretched state during the rotation of the rotor body. The rotor body can return to its original position through the action of the suspension part.

[0011] Furthermore, the suspension part is a spring mechanism that is attached to the outside of the rotor body. One end of the spring mechanism is firmly connected to the rotor assembly receiving space, and the other end of the spring mechanism is firmly connected to the rotor body.

[0012] Furthermore, the spring mechanism is a torsion spring.

[0013] In the implementation process described above, the two ends of the torsion spring are firmly attached to the rotor assembly housing and the rotor body. When the rotor body rotates around the center of the torsion spring, the torsion spring generates a torque or rotational force that pulls the rotor body back to its original position. The torsion spring can store and release angular energy or statically fix the rotor body through a torque arm acting around the center axis of the spring.

[0014] The main housing also includes a front housing and a lower housing. The front housing houses the rotor assembly, while the lower housing is mateably mounted to the front housing. The lower housing is equipped with corresponding metal terminals that are electrically connected to the induction board.

[0015] In the realization process described above, through the electrical connection between the metal terminals and the induction board, the electrical signal of the induction board is transmitted to other devices, thereby realizing the output of the sensor signal of the angular displacement.

[0016] For example, the front housing and the lower housing are optionally provided with a shielding cap, wherein the shielding cap is a metallic shielding cap to shield external magnetic field interference.

[0017] Furthermore, the angular displacement sensor device further comprises a first sealing part by which the lower housing is sealed to the front housing.

[0018] In the realization process described above, the lower housing is assembled with the front housing in a sealed manner by the first sealing part, which prevents excessive contact of the metal terminals with the air and effectively protects the metal terminals from corrosion.

[0019] Furthermore, the rotor assembly further comprises a rotor cover which is mounted covering the rotor assembly receiving space.

[0020] Furthermore, the rotor assembly further comprises a second sealing part through which the rotor cover is mounted in a sealed manner with the rotor assembly receiving space.

[0021] In the implementation process described above, the rotor assembly is sealed in the space between the rotor cover and the rotor assembly housing by covering the rotor assembly housing. This protects the magnet and the suspension part from contact with the external environment, providing water, dust, and rust protection, and effectively extends the service life of the magnet and the suspension part. This leads to an extension of the service life of the angular displacement sensor device.

[0022] In a second aspect, the present application provides an angular displacement sensor device comprising a main body, an induction board, a metal brush, and a rotor assembly;

[0023] The main housing is provided with a rotor assembly receiving space and metal connection terminals;

[0024] The induction board is mounted inside the main housing;

[0025] The rotor assembly is provided for rotation in the rotor assembly receiving space of the main housing, with the metal brush being fixedly mounted to the rotor assembly and electrically connected to the induction board.

[0026] In the realization process described above, the angular displacement sensor device is a contact-based angle sensor, which is different from the non-contact angle sensor described in the first aspect.

[0027] In a third aspect, the present application provides a measuring system comprising the angular displacement sensor device according to any one of the embodiments described in the first aspect.

[0028] Other features and advantages disclosed in the present application will be set forth in the following description, or some features and advantages may be inferred or unmistakably recognized from the description, or they may be apparent from the application of the above-described technique of the present application.

[0037] The present application relates to an angular displacement sensor device and a measuring system that can be applied in the process of measuring angular displacements. The angular displacement sensor device allows the rotor body to be rotatably mounted directly in the rotor assembly receiving space by providing a rotor assembly receiving space on the main body. The mating assembly between the rotor body and the rotor assembly receiving space is simple and convenient. The magnet is provided between the rotor body and the induction board and is firmly mounted at one end of the rotor body that is close to the induction board. This simplifies the assembly structure and reduces manufacturing costs without compromising the measurement accuracy of the rotor assembly. Thus, the angular displacement sensor device can achieve the technical effect of simplified construction and cost reduction.

[0038] Please refer to the Fig. 1 to 4. Fig. 1 is a schematic exploded structural diagram of the first angular displacement sensor device according to an embodiment of the present application. Fig. 2 is a schematic structural diagram in the first view of the first angular displacement sensor device according to an embodiment of the present application. Fig. 3 is a schematic structural diagram in the second view of the first angular displacement sensor device according to an embodiment of the present application. Fig. Figure 4 is a schematic cross-sectional structural diagram of the first angular displacement sensor device according to an embodiment of the present application. The angular displacement sensor device includes a main housing 100, an inductor board 200, and a rotor assembly 300.

[0039] For example, the main housing 100 is provided with a rotor assembly receiving space 110, and the induction board 200 is mounted inside the main housing 100. Arranging the induction board 200 inside the main housing 100 serves to protect the induction board 200 from moisture and interference from the external environment.

[0040] For example, the rotor assembly 300 includes a rotor body 310 and a magnet 320. The rotor body 310 is rotatably mounted in the rotor assembly receiving space 110, and the magnet 320 is provided between the rotor body 310 and the induction board 200 and fixedly mounted at one end of the rotor body 310.

[0041] The shape of the magnet 320 may be rectangular, round, or another shape. It should be noted that the shape of the magnet 320 is given here only as an example and is not limited.

[0042] For example, the rotor body 310 and the magnet 320 serve as the main components of the rotor assembly 300. When the rotor body 310 rotates, the rotor assembly 300, in cooperation with the induction board 200, generates corresponding electrical signals, thereby realizing the sensor measurement of the angular displacement.

[0043] In some embodiments, the angular displacement sensor device allows the rotor body 310 to be rotatably mounted directly in the rotor assembly receiving space 110 by providing a rotor assembly receiving space 110 on the main housing 100. The mating assembly between the rotor body 310 and the rotor assembly receiving space 110 is simple and convenient. The magnet 320 is provided between the rotor body 310 and the induction board 200 and is fixedly mounted at one end of the rotor body 310 that is close to the induction board 200. This simplifies the installation structure and reduces manufacturing costs without compromising the measurement accuracy of the rotor assembly 300. Thus, the angular displacement sensor device can achieve the technical effect of simplified design and cost reduction.

[0044] For example, the rotor assembly 300 further includes a suspension part 330, wherein one end of the suspension part 330 is fixedly connected to the rotor assembly receiving space 110, and another end of the suspension part 330 is fixedly connected to the rotor body 310.

[0045] For example, the suspension part 330 alternates between a natural state and a stretched state during rotation of the rotor body 310. The rotor body 310 can return to its original position through the action of the suspension part 330.

[0046] For example, the suspension part 330 is a spring mechanism that is attached to the outside of the rotor body 310. One end of the spring mechanism is firmly connected to the rotor assembly receiving space 110, and the other end of the spring mechanism is firmly connected to the rotor body 310.

[0047] For example, the spring mechanism is a torsion spring. The two ends of the torsion spring are each firmly attached to the rotor assembly receiving space 110 and the rotor body 310. When the rotor body 310 rotates around the center of the torsion spring, the torsion spring generates a torque or rotational force that pulls the rotor body 310 back to its original position. The torsion spring can store and release angular energy or statically fix the rotor body 310 through a torque arm acting around the center axis of the spring.

[0048] For example, the main housing 100 includes a front housing 120 and a lower housing 130. The front housing 120 is provided with a rotor assembly receiving space 110, while the lower housing 130 is matingly mounted to the front housing 120. The lower housing 130 is provided with corresponding metal terminals 140 that are electrically connected to the induction board 200.

[0049] For example, through the electrical connection between the metal terminals 140 and the induction board 200, the electrical signal of the induction board 200 is transmitted to other devices, thereby realizing the output of the sensor signal of the angular displacement.

[0050] For example, the front housing 120 and the lower housing 130 are optionally provided with a shielding cap 160, wherein the shielding cap 160 is a metallic shielding cap 160 in order to shield external magnetic field interference.

[0051] For example, the angular displacement sensor device further comprises a first sealing part 150 by which the lower housing 130 is sealed to the front housing 120.

[0052] For example, the lower housing 130 is mounted to the front housing 120 in a sealed manner by the first sealing member 150, thereby preventing excessive contact of the metal shielding cap and the metal terminals with the air, so that the metal shielding cap and the metal terminals 140 are effectively protected from corrosion.

[0053] For example, the rotor assembly 300 further includes a rotor cover 340 that is mounted covering the rotor assembly receiving space 110.

[0054] For example, by covering the rotor cover 340 over the rotor assembly receiving space 110, the rotor assembly 300 is sealed in the space between the rotor cover 340 and the rotor assembly receiving space 110. This protects the magnet 320 and the suspension part 330 from contact with the external environment, providing water, dust, and rust protection, and effectively extending the service life of the magnet 320 and the suspension part 330. This leads to an extension of the service life of the angular displacement sensor device.

[0055] For example, the rotor assembly 300 further includes a second sealing member through which the rotor cover 340 is mounted in a sealed manner with the rotor assembly receiving space 110.

[0056] Optionally, the second sealing part can be a sealing ring.

[0057] In some embodiments, the seal between the rotor cover 340 and the rotor assembly receiving space 110 may be achieved using methods other than the sealing ring, such as applying oil, applying wax, or ultrasonic welding, etc. This is merely an example and is not limiting. The seal between the rotor cover 340 and the rotor assembly receiving space 110 may also be achieved using other types of sealing methods depending on the specific needs.

[0058] For example, the embodiments of the present application provide a measuring system that uses the Fig. 1 to 3 illustrated angular displacement sensor device.

[0059] In some embodiments, a shielding cap is provided inside the main housing 100, which is associated with the lower housing 130 or the front housing 120. This can prevent the shielding cap from excessive contact with the air, thereby preventing corrosion of the shielding cap 160 and achieving effective corrosion protection. The shielding cap 160 is arranged inside the main housing 100 of the shell, thereby realizing advantageous device integration.

[0060] In some embodiments, a seal is provided between the main housing 100 and the rotor assembly receiving space 110, as well as between the rotor assembly receiving space 110 and the rotor cover 340. The sealing method may include gasket seals, oil application, wax application, ultrasonic welding, or other methods. This is merely an example and is not limiting.

[0061] The sealing between the main housing 100 and the rotor assembly receiving space 110 enables more effective water and dust protection, thereby increasing the protection level of the angular displacement sensor device to IP67 or higher.

[0062] The seal between the rotor assembly receiving space 110 and the rotor cover 340 can protect the magnet 320 and the suspension part 330 from contact with the external environment and provides protection against water, dust, and corrosion. This can effectively extend the service life of the magnet 320 and the suspension part 330. This further extends the service life of the angular displacement sensor device.

[0063] For example, the Fig. The angular displacement sensor device shown in Figures 1 to 4 is a non-contact angular displacement sensor.

[0064] Please refer to the Fig. 5 and Fig. 6. Fig. 5 is a schematic exploded structural diagram of the second angular displacement sensor device according to an embodiment of the present application. Fig. 6 is a schematic sectional structural diagram of the second angular displacement sensor device according to an embodiment of the present application. Fig. 5 and Fig. The angular displacement sensor device shown in Fig. 6 is a touch-based angular displacement sensor device comprising a main body 100, an induction board 200, a metal brush 400, and a rotor assembly 300.

[0065] For example, the main housing 100 is provided with a rotor assembly receiving space 110. Furthermore, the main housing 100 is provided with metal connection terminals.

[0066] The induction board 200 is mounted inside the main housing 100.

[0067] For example, the rotor assembly 300 is rotatably provided in the rotor assembly receiving space 110 of the main housing 100, and the metal brush 400 is fixedly mounted on the rotor assembly 300. The metal brush 400 is electrically connected to the induction board 200. The metal brush generates corresponding electrical signals depending on the rotation angle of the rotor assembly 300.

[0068] The main housing 100 includes an upper housing, the upper housing having a hollow structure and being penetrated by the rotor assembly 300, wherein a sealing ring 500 is mounted centrally on the rotor assembly 300 to separate an upper and a lower space, thus making it water and dust proof.

[0069] The Fig. 5 and Fig. The angular displacement sensor device shown in Figure 6 is a touch-based angle sensor and differs from the one shown in the Fig. 1 to 4 shown non-contact angle sensor.

[0070] In some embodiments, the Fig. 5 and Fig. The angular displacement sensor device shown in Figure 6 also includes a sealing ring 500 mounted on the rotor assembly 300. Optionally, the rotor cover 340 is mounted covering the rotor assembly receiving space 110.
