Description

Technical Field

[0001] The present invention relates to an instrument indicating system, in particular to an instrument indicating system using a pointer. Background Art

[0002] Existing instrument indication systems are mainly divided into the following two categories:

[0003] The first category: electronic digital displays. Sensors collect information and transmit it to the MCU. The MCU controller converts the received information into digital form on the display screen, such as electronic thermometers, electronic hygrometers, and electronic speedometers. Electronic digital displays can also display information by rotating a virtual pointer on the screen. The advantage of using this type of electronic digital display is its high display precision and accuracy. However, its disadvantage is that it cannot be displayed using a physical pointer.

[0004] The second category uses a physical pointer to display. This type of pointer display system uses different operating methods depending on the indicator. For example, a pointer-type thermometer / hygrometer uses the principle that two different metals expand differently when the temperature changes. Specifically, the main component is a multi-layer metal sheet composed of two or more metal sheets laminated together. To improve temperature measurement sensitivity, the metal sheets are usually made into a spiral coil. When the temperature of the multi-layer metal sheet changes, the metal layers expand or contract to different degrees, causing the spiral coil to wind or unwind. Because one end of the spiral coil is fixed and the other end is free to rotate and connected to the pointer, when the bimetallic strip senses the temperature change, the pointer can indicate the temperature on a circular graduated scale. For example, a pointer-type hygrometer uses a humidity sensor element. There are hair-type and metal springs coated with a high-molecular-weight hydrophilic plastic material. The principle is variable length. The element changes its length with changes in air humidity. The displacement caused by the length change drives the pointer shaft, causing it to move on the dial, thereby measuring humidity. For example, a pointer-type barometer uses a thin film cell made of elastic metal as its sensing element. It converts atmospheric pressure into elastic displacement of the cell, which in turn drives a pointer through a lever and transmission mechanism. When the pointer deflects clockwise, it indicates an increase in pressure; conversely, when it deflects counterclockwise, it indicates a decrease in pressure. When the elastic stress of the cell balances the atmospheric pressure, the pointer stops rotating, and the pressure indicated by the pointer is the prevailing atmospheric pressure. Compared to electronic digital displays, the aforementioned pointer-type temperature, humidity, and barometers suffer from slow response and long lag times, which can be as long as 10 to 20 minutes. They are unable to respond to even small changes and have large display errors, typically within ±5% but exceeding ±10%. They also have significant annual drift, are unstable, and are susceptible to aging and deterioration, shortening their lifespan. Their advantage lies in their intuitive display of current information through a pointer. However, they lack accurate and reliable measurement, and the displayed value is for reference only. In addition to the pointer-type temperature, humidity, and barometers mentioned above having the above-mentioned technical defects, other systems that use pointer-type indications also have the same technical defects.

[0005] The second category of physical pointer displays utilizes mechanical transmission components. However, their internal structure utilizes a bimetallic ring that expands and contracts due to thermal expansion. This results in delayed and unclear indications. During production, the pointers must be installed in a standard environment using specialized equipment, requiring high levels of technical expertise. Errors must also be calibrated or repaired in a standard environment using specialized calibration equipment. This results in high production and maintenance costs.

[0006] Therefore, there is an urgent need for a pointer-type instrument display system with mechanical gear transmission that is accurate in indication, quick in response, sensitive, and capable of forward and reverse rotation. Summary of the Invention

[0007] The object of the present invention is to provide a pointer-type instrument display system with mechanical gear transmission that has accurate indication, fast response, sensitivity and can perform forward and reverse rotation.

[0008] To achieve the above-mentioned purpose, the present invention provides a pointer-type instrument indication system, which includes an instrument panel, a transmission structure, a pointer, a rotor magnet, a first coil motor, a second coil motor, a sensor and an MCU controller; the instrument panel has identification information; the transmission structure includes multi-stage gears that mesh with each other in sequence, the starting end of the multi-stage gear is the first stage gear, and the end end of the multi-stage gear is the pointer gear; the pointer is installed on the pointer gear shaft, and the pointer rotates relative to the instrument panel by rotating the transmission structure to present identification information with different readings; the rotor magnet is fixedly connected to the first stage gear; the first coil motor is connected to the rotor magnet in a magnetic transmission manner; the second coil motor is connected to the rotor magnet in a magnetic transmission manner; the sensor is used to collect information; the The sensor is electrically connected to the MCU controller, and the sensor transmits the collected information to the MCU controller; the information of the sensor currently received by the MCU controller is current information, and the information of the sensor received by the MCU controller last time is past information; the MCU controller compares the current information and the past information; when the comparison result becomes larger, the MCU controller independently controls the operation of the first coil motor according to the comparison result and drives the transmission structure to drive the pointer to rotate forward through the rotor magnet; the MCU controller compares the current information and the past information; when the comparison result becomes smaller, the MCU controller independently controls the operation of the second coil motor according to the comparison result and drives the transmission structure to drive the pointer to rotate reversely through the rotor magnet.

It can be seen that the pointer-type instrument indication system of the present invention creatively realizes the forward and reverse adjustment technical means of the physical pointer under the drive of the transmission structure of the mechanical structure, and the pointer can be reversed, so that the pointer-type instrument indication system of the present invention is accurate, responsive and sensitive.

[0027] The technical solutions in the embodiments of the present application are clearly and completely described below in conjunction with specific implementation examples and the accompanying drawings, and the technical solutions of the present invention are explained. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0029] like Figure 1 - Figure 3 As shown, the pointer instrument indication system 100 of the present invention includes an instrument panel 1, a transmission structure 2, a pointer 3, a rotor magnet 4, a first coil motor 5, a second coil motor 6, a sensor 7, and an MCU controller 8. The instrument panel 1 of the present invention has identification information 11 for reading current information; specifically, the identification information 11 is at least one of scale information, digital information, letter information, pattern information, or shape information; as shown in FIG. Figure 2The illustrated embodiment shows a marking 11 as scale information. The numerical information of the present invention is preferably Arabic numerals or Roman numerals; the alphabetic information of the present invention is preferably English letters or Greek letters; the pattern information of the present invention is preferably an internationally accepted simple pattern; and the shape information of the present invention is preferably an internationally accepted simple shape. The transmission structure 2 of the present invention comprises a plurality of gears meshing in sequence, with the first gear 2A at the beginning and the pointer gear 2B at the end. The pointer 3 of the present invention is mounted on the pointer gear 2B. The pointer 3 rotates relative to the instrument panel 1 as the transmission structure 2 rotates, presenting different readings of identification information. The rotor magnet 4 of the present invention is fixedly connected to the first gear 2A. The first coil motor 5 of the present invention is magnetically connected to the rotor magnet 4; the second coil motor 6 of the present invention is magnetically connected to the rotor magnet 4. The sensor 7 of the present invention is used to collect information; the sensor 7 is electrically connected to the MCU controller 8 and transmits the collected information to the MCU controller 8. In the present invention, the information currently received by the sensor 7 by the MCU controller 8 is considered current information, while the information previously received by the sensor 7 by the MCU controller 8 is considered past information. The MCU controller 8 of the present invention compares the current information with the past information; if the comparison result becomes larger, the MCU controller 8 independently controls the operation of the first coil motor 5 according to the comparison result and drives the transmission structure 2 to drive the pointer 3 to rotate in the forward direction through the rotor magnet 4. The MCU controller 8 of the present invention compares the current information with the past information; if the comparison result becomes smaller, the MCU controller 8 independently controls the operation of the second coil motor 6 according to the comparison result and drives the transmission structure 2 to drive the pointer 3 to rotate in the reverse direction through the rotor magnet 4. It can be seen that the pointer-type instrument indication system of the present invention uses a sensor 7 that can accurately and quickly respond to obtain current information, and uses a precision mechanical transmission structure 2 mainly composed of gears to drive the pointer 3 to rotate, thereby accurately, quickly and sensitively presenting the current information obtained by the sensor 7 through the rotation of the pointer 3. More specifically, the present invention compares the current information and past information collected by the sensor 7 through the MCU controller 8; and chooses to independently control the first coil motor 5 to work and drive the pointer 3 to rotate forward to the real-time position corresponding to the current information through the transmission structure 2; or chooses to independently control the second coil motor 6 to work and drive the pointer 3 to rotate reversely to the real-time position corresponding to the current information through the transmission structure 2; that is, the present invention can quickly and sensitively realize the forward and reverse movement of the pointer 3 through the cooperation of the first coil motor 5, the second coil motor 6, the transmission structure 2 and the MCU controller 8, on the one hand, and on the other hand, make the pointer 3 rotate to the real-time position corresponding to the current information through forward rotation or reverse rotation with the minimum rotation amplitude. Therefore, the pointer-type instrument display system 100 of the present invention has accurate indication, fast response, sensitivity and can be reversed, and is very suitable for wide promotion and use, and is particularly suitable for replacing existing instrument-type indicating devices. The following continues in combination Figure 1 - Figure 8 The pointer instrument display system 100 of the present invention is further described in detail:

[0030] It is worth noting that the forward rotation in this application document refers to the rotation in the opposite direction of the reverse rotation; it can be understood that the forward rotation in this application is the clockwise rotation of the pointer 3, and the reverse rotation is the counterclockwise rotation of the pointer 3.

[0031] like Figure 3 - Figure 5As shown, the first coil motor 5 of the pointer instrument indication system 100 of the present invention includes a first stator plate 51 and a first coil 52 wound around the first stator plate 51. The first coil 52 is electrically connected to the MCU controller 8. Specifically, the starting end of the first coil 52 is electrically connected to the terminal post 53; the trailing end of the first coil 52 is electrically connected to the terminal post 54; the terminal posts 53 and 54 are connected to pins on the MCU controller 8. The second coil motor 6 of the present invention includes a second stator plate 61 and a second coil 62 wound around the second stator plate 61. The second coil 62 is electrically connected to the MCU controller 8. Specifically, the starting end of the second coil 62 is electrically connected to the terminal post 63; the trailing end of the second coil 62 is electrically connected to the terminal post 64; the terminal posts 63 and 64 are connected to pins on the MCU controller 8. The MCU controller 8 of the present invention compares the current information with the past information; when the comparison result becomes larger, the MCU controller 8 inputs a first drive pulse current to the first coil 52, the first coil motor 5 generates a magnetic field and drives the first-stage gear 2A to rotate through the rotor magnet 4, the first-stage gear 2A rotates and drives the pointer gear 2B through the transmission structure 2 to synchronously drive the pointer 3 to rotate forward; when the comparison result becomes smaller, the MCU controller 8 of the present invention inputs a second drive pulse current to the second coil 62, the second coil motor 6 generates a magnetic field and drives the first-stage gear 2A to rotate through the rotor magnet 4, the first-stage gear 2A rotates and drives the pointer gear 2B through the transmission structure 2 to synchronously drive the pointer 3 to rotate in the reverse direction. It can be seen that when the present invention is in use, when the MCU controller 8 compares the current information with the past information, the comparison result becomes larger, and the pointer 3 can reach the real-time position corresponding to the current information by rotating in the forward direction, and this forward rotation of the pointer 3 is also the direction with the smallest adjustment amplitude; specifically, at this time, the MCU controller 8 inputs the first drive pulse current to the first coil 52, and the first coil 52 generates a magnetic field after the first drive pulse current is passed through it. The direction of the magnetic field can be known according to the winding direction of the first coil 52 and the direction of the first drive pulse current combined with the right-hand rule; the magnetic field generated after the first coil 52 is passed through the first drive pulse current repel each other with the magnetic field generated by the rotor magnet 4 fixed on the first-stage gear 2A, thereby driving the first-stage gear 2A to rotate (the rotor magnet and the first-stage gear rotate synchronously), and the first-stage gear 2A rotates and drives the pointer 3 to rotate quickly in the forward direction to the real-time position corresponding to the current information, thereby realizing the characteristics of the present invention of accurate indication, fast response and sensitive information display.When the present invention is in use, when the MCU controller 8 compares the current information with the past information, the comparison result becomes smaller, and the pointer 3 can reach the real-time position corresponding to the current information by reverse rotation, and this reverse rotation of the pointer 3 is also the direction with the smallest adjustment amplitude; specifically, at this time, the MCU controller 8 inputs a second drive pulse current to the second coil 62, and the second coil 62 generates a magnetic field after the second drive pulse current is passed through it. The direction of the magnetic field can be known according to the winding direction of the second coil 62 and the direction of the second drive pulse current combined with the right-hand rule; the magnetic field generated by the second coil 62 after the second drive pulse current is passed through it repel each other with the magnetic field generated by the rotor magnet 4 fixed on the first-stage gear 2A, thereby driving the first-stage gear 2A to rotate (the rotor magnet and the first-stage gear rotate synchronously), and the first-stage gear 2A rotates and drives the pointer 3 to quickly reverse and rotate to the real-time position corresponding to the current information, thereby realizing the characteristics of the present invention of accurate indication, fast response and sensitive information display. It can be seen that the present invention, through the cooperation of the first coil motor 5 and the second coil motor 6 of the specific structure with the rotor magnet 4, the MCU controller 8 and the transmission structure 2, quickly and conveniently realizes the forward and reverse functions of the pointer 3 based on only one transmission structure, and has a simple structure and is easy to use; it can achieve an ultra-thin and ultra-small design.

[0032] It is worth noting that the first coil motor 5 and the second coil motor 6 of the present invention are controlled by the MCU control 8 and work independently, that is, when the first coil motor 5 is working, the second coil motor 6 is stopped, and when the second coil motor 6 is working, the first coil motor 5 is stopped. At the same time, when the first coil motor 5 of the present invention is working, the rotation direction of the driven first-stage gear 2A is the first direction; when the second coil motor 6 of the present invention is working, the rotation direction of the driven first-stage gear 2A is the second direction; the first direction and the second direction are always opposite, that is, one direction is forward and the other must be reverse. In addition, the magnitude of the rotation amplitude of the pointer 3 driven by the present invention is determined by the pulse time of the corresponding first drive pulse current and the second pulse current. This is common knowledge in the field and will not be described in detail here.

[0033] Preferably, the first coil 52 and the second coil 62 of the pointer-type instrument indicator system of the present invention have the same winding direction, and the first drive pulse current and the second drive pulse current have the same current direction. However, the magnetic fields generated on the stator plates are in opposite directions, thereby changing the rotation direction of the rotor magnet 4. This design allows the first coil motor 5 and the second coil motor 6 to have identical structures, significantly reducing manufacturing costs.

[0034] like Figure 3FIG. 2 shows a specific structure of the transmission structure 2 of the present invention. The transmission structure 2 is a four-stage gear structure; specifically, the transmission structure 2 includes a first-stage gear 2A, a second-stage gear 22, a third gear 23, and a pointer gear 2B serving as the fourth-stage gear, which mesh with each other in sequence. Those skilled in the art may add any number of gears between the first-stage gear 2A and the pointer gear 2B to achieve the desired effect, as required. Such addition and subtraction are well known to those skilled in the art and will not be further elaborated here.

[0035] like Figure 3 - Figure 5 As shown, preferably, the first coil motor 5 and the second coil motor 6 of the pointer instrument indicating system 100 of the present invention are arranged side by side, and the free ends of the first stator plate 51 and the second stator plate 61 are two concentric circle structures with different diameters. The two concentric circle structures with different diameters are arranged opposite to each other and form an S / N electromagnetic field area 41. The rotor magnet 4 of the present invention is fixedly connected to the first-stage gear 2A and is located in the S / N electromagnetic field area 41.

[0036] like Figure 3 and Figure 6 - Figure 8As shown, preferably, the center of the pointer gear 2B of the pointer-type instrument indicating system 100 of the present invention forms a rotational center O. One side of the pointer gear 2B has an outwardly extending, tilted, suspended spring piece 91. There are at least two spring pieces 91, which are evenly distributed around the rotational center O and are arranged in a compressed, pressing manner. Because the pointer gear 2B in the transmission structure 2 of the present invention has spring pieces 91 evenly distributed around the rotational center O, and these spring pieces 91 extend outwardly and tilted from one side of the pointer gear 2B and are arranged in the air, the spring pieces 91 form an obliquely arranged, suspended elastic arm structure on the pointer gear 2B. During use, the spring piece 91 of the pointer gear 2B of the present invention is pressed against other gears stacked therewith or against the housing. The spring piece 91 is pressed toward the pointer gear 2B, so that the spring piece 91 of the pointer gear 2B of the present invention is adaptively compressed to a suitable height, thereby significantly reducing the axial clearance between the pointer gear 2B of the present invention and the other gears, effectively avoiding the problem of excessive cumulative superposition clearance and vibration and slippage in the transmission structure of multiple meshing gears, so that the pointer 3 driven by the transmission structure 2 runs smoothly without interference, friction, or collision. At the same time, the friction of the gear rotation is increased by the spring piece 91 being pressed, making the gear rotation more stable and smooth, thereby further avoiding vibration and slippage of the gear, further ensuring the smooth operation of the pointer 3 driven by the transmission structure 2, and further ensuring that the pointers do not interfere, rub, or collide. It can be seen that the transmission structure 2 of the present invention has a small volume and thin thickness due to the significant reduction in the axial clearance between the gears, which makes the transmission structure 2 have an ultra-thin structural characteristic, thereby making the present invention have an ultra-thin and ultra-low tube axis structural characteristic, and the pointer 3 driven by it runs smoothly without interference and friction. The effect is significant, the practicability is strong, and it is very suitable for widespread promotion and use.

[0037] like Figure 6 - Figure 8 As shown, preferably, a small toothed disc 92 for engagement is protruded outward from the rotation center O of one side of the pointer gear 2B of the pointer-type instrument indicating system 100 of the present invention; specifically, Figure 3 In the illustrated embodiment, the pinion 92 meshes with the third-stage gear 23, which in turn drives the pointer gear 2B. A rotational axis 93 protrudes outward from the rotation center O on the other side of the pointer gear 2B. This rotational axis 93 and the spring 91 are located on the same side of the pointer gear 2B. This rotational axis 93 extends beyond the dial 1 and connects to the pointer 3.

[0038] like Figure 6 - Figure 8As shown, preferably, the spring clip 91 of the pointer-type instrument indicating system 100 of the present invention is arc-shaped, with the spring clip 91 being distributed with equal diameters around the rotation center O. The arc-shaped curvature of the spring clip 91 of the present invention surrounds the rotation center O. The arc-shaped spring clip 91 allows for smoother, synchronized rotation of the spring clip 91 when the pointer gear 2B rotates. The equally distributed spring clip 91 ensures that, after being pressed and compressed, the entire pointer gear 2B is evenly stressed. Furthermore, the present invention preferably has three spring clips 91, although two, four, or five spring clips 91 are also possible.

[0039] like Figure 6 - Figure 8 As shown, preferably, the free end of the spring clip of the pointer-type instrument indicating system of the present invention has a circular chamfered structure. The free end 94 of the spring clip 91 of the present invention has a circular chamfered structure, further improving the smooth rotation of the pointer gear 2B. More specifically, the free end 94 of the spring clip 91 of the present invention is bent toward the pointer gear 2B to form a curved structure.

[0040] It is worth noting that the compression in the compressed setting of the spring 91 mentioned in this application document refers to: the change in the inclination angle of the spring 94 relative to the gear body 95 of the pointer gear 2B, which can also be understood as the change in the distance between the spring 91 and the gear body 95, rather than the length of the spring 91 being compressed or stretched.

[0041] Preferably, the sensor 7 of the pointer-type instrument indicating system 100 of the present invention is a temperature sensor, a humidity sensor, a pressure sensor, an air pressure sensor, a speed sensor or a liquid level sensor. When the sensor of the present invention is a temperature sensor, the pointer-type instrument indicating system of the present invention is used to indicate the current temperature information through a pointer. When the sensor of the present invention is a humidity sensor, the pointer-type instrument indicating system of the present invention is used to indicate the current humidity information through a pointer. When the sensor of the present invention is a pressure sensor, the pointer-type instrument indicating system of the present invention is used to indicate the current pressure information through a pointer. When the sensor of the present invention is an air pressure sensor, the pointer-type instrument indicating system of the present invention is used to indicate the current air pressure information through a pointer. When the sensor of the present invention is a speed sensor, the pointer-type instrument indicating system of the present invention is used to indicate the current speed information through a pointer. When the sensor of the present invention is a liquid level sensor, the pointer-type instrument indicating system of the present invention is used to indicate information such as the current water level or oil level through a pointer.

[0042] Combine Figure 1 - Figure 8As shown, (1) the pointer-type instrument indication system 100 of the present invention adopts a sensor 7 that is accurate and responsive to obtain current information, and adopts a precision mechanical transmission structure 2 mainly composed of gears to drive the pointer 3 to rotate, thereby accurately, quickly and sensitively presenting the current information obtained by the sensor 7 through the rotation of the pointer 3; the pointer-type instrument indication system 100 of the present invention creatively combines the sensor 7 of the electronic device with the transmission structure 2 of the mechanical structure in a coordinated and unified manner, effectively realizing the pointer-type display of the current information, and at the same time, this pointer-type display of the current information is accurate, responsive and sensitive, and perfectly combines the advantages of the traditional "electronic digital display" and "physical pointer display", with outstanding substantive characteristics and significant progress. (2) The present invention compares the current information and past information collected by the sensor 7 through the MCU controller 8, and selects to independently control the first motor coil motor 5 to work and drive the pointer 3 to rotate forward to the real-time position corresponding to the current information through the transmission structure 2, or selects to control the second coil motor 6 to work and drive the pointer 3 to rotate reversely to the real-time position corresponding to the current information through the transmission structure; that is, the present invention can quickly and sensitively realize the forward and reverse movement of the pointer 3 through the cooperation of the first coil motor 5, the second coil motor 6, the transmission structure 2 and the MCU controller 8, on the one hand, and make the pointer 3 rotate to the real-time position corresponding to the current information through forward rotation or reverse rotation with the minimum rotation amplitude. It can be seen that the pointer-type instrument indication system 100 of the present invention creatively realizes the forward and reverse adjustment technical means of the physical pointer under the drive of the transmission structure of the mechanical structure, and the pointer 3 can be reversed, so that the pointer-type instrument indication system 100 of the present invention can indicate accurately, respond quickly and be sensitive.
