Description

Technical Field

[0001] This utility model belongs to the field of joystick technology, specifically, it relates to a small Hall effect joystick. Background Technology

[0002] A Hall effect sensor, based on the Hall effect, can detect the position, speed, and direction of an object by measuring changes in a magnetic field. Currently, a Hall effect sensor consists of a Hall element, a magnet, and a circuit board. It converts changes in the magnetic field into an electrical signal output, thereby enabling the detection of the object's position. This sensor is widely used in robotics, game controllers, and other fields.

[0003] Research revealed that existing technologies rely solely on Hall effect sensors for signal determination and output; however, under conditions of external signal interference and magnetic loss, signal transmission and determination become unstable, leading to inaccurate signal transmission and thus affecting actual operation.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To solve the technical problem of signal interference, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] A small Hall effect rocker includes a rocker assembly for remote control operation. The rocker assembly includes a housing, a base, an assembly block, a sensor module, and a magnetic module. The assembly block is disposed within the housing. Both the sensor module and the magnetic module are disposed within the assembly block. The magnetic module is located within the sensor module. The base and the magnetic module are connected. The housing is used to shield against external magnetic fields.

[0007] In a preferred embodiment of the present invention, the bottom of the cover is threadedly connected to a base plate, and a washer is provided between the cover and the base plate, with the washer in close contact with the corresponding cover and base plate.

[0008] In a preferred embodiment of the present invention, a limiting ring is provided at the upper end of the cover, the limiting ring is fixedly connected to the cover, and the inner side of the limiting ring is made of rubber.

[0009] In a preferred embodiment of the present invention, a rod extends from the bottom of the base, the rod is fixedly connected to the magnetic module, and a limiting ring is fixedly connected to the middle of the rod, with the limiting ring and the positioning ring abutting against each other.

[0010] In a preferred embodiment of the present invention, a retaining ring is snapped into the bottom of the base, a rubber sleeve is fixedly connected to the retaining ring, and a connecting ring is fixedly connected to the bottom of the rubber sleeve.

[0011] In a preferred embodiment of this utility model, the rubber sleeve is fitted over the outside of the rod body, and the connecting ring is connected to the upper end of the assembly block by a thread.

[0012] In a preferred embodiment of this utility model, the sensor module consists of a Hall effect sensor and a displacement sensor, and the Hall effect sensor and the displacement sensor are symmetrically arranged.

[0013] In a preferred embodiment of this utility model, a torsion spring is provided in the middle of the magnetic module, and the ends of the torsion spring abut against the sensor module and the magnetic module respectively.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. This small Hall effect rocker has a housing made of iron-nickel alloy and coated with an anti-corrosion coating. The high shielding properties of the iron-nickel alloy enable it to shield against external magnetic fields, preventing external magnetic fields from interfering with the internal magnetic field of the device and thus affecting the accuracy of the device.

[0016] 2. This small Hall effect joystick uses a Hall effect sensor and a displacement sensor in the sensor module to measure the position, speed and direction of the object by measuring the rotational displacement of the magnetic module in two ways. By comparing and calibrating the two sets of data, the actual operation command is accurately transmitted, avoiding the situation where the data is inaccurate and the operation command cannot be transmitted due to the transmission of only one set of data.

[0017] 3. This small Hall effect rocker has a rubber sleeve that makes tight contact with the limiting ring, thereby sealing the upper part of the cover. The bottom gasket isolates it from external moisture, preventing the device from short-circuiting and becoming unusable when it gets wet, thus providing a good water-proof effect.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] Please see Figure 1-5 A small Hall effect rocker includes a rocker assembly for remote control operation. The rocker assembly includes a housing 1, a base 2, an assembly block 4, a sensor module 41, and a magnetic actuation module 42. The assembly block 4 is disposed inside the housing 1. Both the sensor module 41 and the magnetic actuation module 42 are disposed inside the assembly block 4. The magnetic actuation module 42 is located inside the sensor module 41. The base 2 is connected to the magnetic actuation module 42. The housing 1 is used to shield against external magnetic fields.

[0028] In use, the base 2 is manually pushed, causing the magnetic module 42 to rotate within the sensor module 41. The rotational displacement of the magnetic module 42 is detected by the module within the sensor module 41, thereby transmitting the control command based on the rotation amplitude of the magnetic module 42 driven by the base 2. The sensor module 41 performs composite verification of the control command to ensure accuracy. Furthermore, the cover 1 shields the external magnetic field, preventing unstable signal transmission and judgment of the internal sensor module 41, which could lead to inaccurate signal transmission and affect actual operation.

[0029] The bottom of the cover 1 is threadedly connected to the base plate 12. A washer 13 is provided between the cover 1 and the base plate 12. The washer 13 is in close contact with the corresponding cover 1 and base plate 12. A limit ring 11 is provided at the upper end of the cover 1. The limit ring 11 is fixedly connected to the cover 1, and the inner side of the limit ring 11 is made of rubber. A rod extends from the bottom of the base 2. The rod is fixedly connected to the magnetic module 42. A limiting ring 43 is fixedly connected to the middle of the rod. The limiting ring 43 abuts against the limit ring 11.

[0030] Before use, the base 2 and the rod are connected by fasteners, and the rod and the magnetic module 42 are connected by fasteners. The magnetic module 42 is placed inside the sensor module 41, and the sensor module 41 is connected to the assembly block 4 by fasteners. Before assembling the rod and the magnetic module 42, the rod is passed through the assembly block 4, and the magnetic module 42 is placed inside the assembly block 4. Then, the assembly block 4 is connected to the cover 1 by threads, and the washer 13 is placed between the base plate 12 and the cover 1. Then, the base plate 12 is assembled with the limiting ring 11 by threads to complete the assembly of the device. The setting of the limiting ring 11 and the washer 13 achieves the isolation from external moisture, preventing the device from short-circuiting internal components and becoming unusable after encountering water, thus providing a good water-proof effect for the device.

[0031] The cover 1 is made of iron-nickel alloy and is coated with an anti-corrosion coating. The high shielding properties of the iron-nickel alloy can shield the external magnetic field, preventing the external magnetic field from interfering with the internal magnetic field of the device and thus affecting the accuracy of the device.

[0032] The base 2 has a retaining ring 32 at its bottom, a rubber sleeve 31 fixedly connected to the retaining ring 32, a connecting ring 3 fixedly connected to the bottom of the rubber sleeve 31, the rubber sleeve 31 is sleeved on the outside of the rod, and the connecting ring 3 is connected to the upper end of the assembly block 4 by a thread.

[0033] By setting the connecting ring 3, rubber sleeve 31 and retaining ring 32, the structure at the bottom of the base 2 is protected, avoiding the exposed parts such as the rod and the limiting ring 43, which could cause direct impact damage to the parts. After the base 2 rotates and tilts to the edge, the base 2 drives the rod and the limiting ring 43 to contact and abut against the limiting ring 11. The limiting ring 11 limits the limiting ring 43, thereby limiting the swing angle of the base 2.

[0034] Furthermore, the rubber sleeve 31 is in close contact with the limiting ring 11, thereby sealing the upper end of the cover 1. The bottom gasket 13 is used to isolate the device from external moisture, preventing the internal components from short-circuiting and becoming unusable after the device comes into contact with water, thus providing a good water-proof effect for the device.

[0035] The sensor module 41 consists of a Hall effect sensor and a displacement sensor, and the Hall effect sensor and the displacement sensor are symmetrically arranged. The magnetic module 42 has a torsion spring in the middle, and the ends of the torsion spring abut against the sensor module 41 and the magnetic module 42 respectively.

[0036] The position, speed and direction of the object are measured in two ways by the Hall effect sensor and displacement sensor in the sensor module 41. The actual operation command is accurately transmitted by comparing and calibrating the two sets of data, avoiding the situation where the data is inaccurate and the operation command cannot be transmitted when only one set of data is transmitted. The torsion spring between the sensor module 41 and the magnetic module 42 resets the magnetic module 42 after it swings.

[0037] It is worth noting that the Hall effect sensor calculates the offset angle data based on the Hall voltage obtained by the Hall sensor, responds to the offset angle data to form a complete cycle at the current moment, and then calculates the total offset angle. After obtaining the elastic coefficient of the shaft, the real-time torque of the shaft is calculated based on the total offset angle and the elastic coefficient of the shaft. Using the Hall effect method can reduce the product size, realize a miniature non-contact dynamic torque sensor, and can also be used for contact static torque sensors. A calibration scheme for calculating torque by phase difference is designed simultaneously, which can update the calibration in real time, further improving the high-precision torque measurement requirements, which is beneficial for long-term calibration work, and can issue abnormal alarms based on trigger conditions, as well as facilitate subsequent data processing to form standard torque, enriching the current torque measurement work and requirements. The Hall effect sensor has been disclosed in the prior art of a torque measurement method based on the Hall effect in CN117647345B, which will not be described in detail here.

[0038] It is worth noting that the displacement sensor includes a resistive element, which comprises two interconnected and structurally identical semi-circular bodies. The surface of the semi-circular body with an arc-shaped working band is designated as the upper surface. A first connecting end is formed by thinning from bottom to top near the first end of the semi-circular body, and a vertical first connecting hole is provided on the first connecting end. A second connecting end is formed by thinning from top to bottom near the second end of the semi-circular body, and a vertical second connecting hole is provided on the second connecting end. The first and second connecting holes of one semi-circular body are respectively connected to the second and first connecting holes of the other semi-circular body via screws. By designing the resistive element as two interconnected semi-circular bodies with identical structures, the synchronization of the two output signals and the sensor accuracy are significantly improved, and the sensor is easier to manufacture. The displacement sensor has already been disclosed in the existing technology of a miniature dual-redundant angular displacement sensor with rotation angle limiting function, CN112504114B, and will not be elaborated upon here.

[0039] Working principle: Before use, the base 2 and the rod are connected by fasteners, and the rod is connected to the magnetic module 42 by fasteners. The magnetic module 42 is placed inside the sensor module 41, and the sensor module 41 is connected to the assembly block 4 by fasteners. Before assembling the rod and the magnetic module 42, the rod is passed through the assembly block 4, and the magnetic module 42 is placed inside the assembly block 4. Then, the assembly block 4 is connected to the cover 1 by threads, and the washer 13 is placed between the base plate 12 and the cover 1. Then, the base plate 12 is connected to the limiting ring 11 by threads, thus assembling the device. The limiting ring 11 and the washer 13 isolate the device from external moisture. The connecting ring 3, the rubber sleeve 31, and the retaining ring 32 protect the structure at the bottom of the base 2, preventing the rod and the limiting ring from being damaged. The components such as the restraining ring 43 are exposed, which can cause direct impact damage to the components. After the base 2 rotates and tilts to the edge, the base 2 drives the rod and the restraining ring 43 to contact and abut against the limiting ring 11. The limiting ring 11 limits the restraining ring 43, thereby limiting the swing angle of the base 2. The Hall effect sensor and displacement sensor in the sensor module 41 measure the position, speed and direction of the object by two methods. By comparing and calibrating the two sets of data, the actual operation command is accurately transmitted, avoiding the situation where the data is inaccurate and the operation command cannot be transmitted due to the transmission of only one set of data. The torsion spring between the sensor module 41 and the magnetic module 42 resets the magnetic module 42 after it swings.
