Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments of the present invention and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order to solve the technical problem that in the prior art, the device for detecting the rotation angle of an appliance such as mechanical equipment and electrical equipment is easy to be influenced by illumination when the device using the infrared detection principle is used for detecting the angle, and the device using the pressure detection principle is required to detect the angle in a contact manner, the invention is further described by referring to the description and the embodiment of the drawings:
it is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the present application. As used herein, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise, and the terms "comprising" and "having" and any variation thereof are intended to cover a non-exclusive inclusion, e.g., a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
As shown in fig. 1-2, the invention discloses an angle detection device, which is used for judging the rotation angle of an appliance to be detected according to the change of a capacitance signal detected by a touch detection principle by influencing the capacitance of the detection device according to the change of the rotation angle of the appliance to be detected, so as to realize the detection of the rotation angle and the direction of the appliance to be detected.
The angle detection device specifically comprises a first electrode element 1, a second electrode element 2 and a touch chip, wherein the first electrode element 1 is opposite to the second electrode element 2 at intervals, the intervals are arranged so that the first electrode element 1 and the second electrode element 2 are not in direct contact, but form a space distance, when the angle detection device works, the first electrode element 1 and the second electrode element 2 and the space distance can form a detection space, the first electrode element 1 rotates relative to the second electrode element 2 in the rotation process of an appliance to be detected, the first electrode element 1 or the second electrode element 2 is connected with the touch chip, the touch chip is an external chip and is electrically connected with one electrode element of the first electrode element 1 or the second electrode element 2, and the rotation axis of the first electrode element 1 and/or the rotation axis of the second electrode element 2 is parallel to the rotation axis of the appliance to be detected.
The rotation axis of the first electrode element 1 or the second electrode element 2 is relatively parallel to the rotation axis of the to-be-detected tool, and as the first electrode element 1 rotates relative to the second electrode element 2, when one of the electrode elements is fixedly arranged, the tool rotates in the angle detection process, the first electrode element follows the rotation, the capacitance formed between the first electrode element 1 and the second electrode element 2 changes, and further angle detection is realized, and if the rotation axis of the first electrode element 1 is relatively parallel to the rotation axis of the to-be-detected tool, the rotation angle of the tool cannot be accurately detected.
The first electrode element 1 and the second electrode element 2 are arranged in parallel at intervals to form a capacitor element, in the rotating process of the device to be detected, the first electrode element 1 rotates relative to the second electrode element 2 to cause capacitance change, specifically, when the first electrode element 1 and the second electrode element 2 rotate at different speeds or in different directions, the areas of the first electrode element 1 and the second electrode element 2 are not all overlapped, after the areas are staggered, the capacitance is changed by changing the corresponding overlapped electrode element areas, so that the test is realized by changing the opposite overlapped areas of the first electrode element 1 and the second electrode element 2, and the touch chip is used for detecting capacitance values and determining the rotating angle according to the capacitance value change.
In the above example, according to the principle of simulating capacitor element+capacitive touch, a lower voltage may be applied to the first electrode element 1 or the second electrode element 2, and an alternating current is generally used, and the first electrode element 1 or the second electrode element 2 is connected through a touch chip to detect and determine the variation of capacitance, so as to obtain the rotation angle of the to-be-detected device according to the relationship between the variation of capacitance and the angle.
In addition, the relation between the capacitance change amount (capacitance value) and the angle is determined in advance by multiple analog detection and database establishment.
In some embodiments, the touch chip is provided with a detection port, and the detection port of the touch chip is connected with the first electrode element 1, or the detection port of the touch chip is connected with the second electrode element 2.
In the above example, the first electrode element 1 or the second electrode element 2 is electrically connected to the touch chip, and may be connected by an electrode wire, or other connection methods may be adopted. The touch chip has data processing capability, and the touch chip detects the capacitance change based on the detection port so as to judge the capacitance value.
In a specific example, the detection port of the touch chip is an I/O detection port.
In some embodiments, the touch chip calculates a corresponding angle according to the capacitance value of a certain point, and the touch chip is connected with the display device to display the angle. The structure and principle of the display device are prior art, and are not repeated in the present application.
In a specific example, the touch chip is a capacitive touch chip.
In some embodiments, when the first electrode element 1 or the second electrode element 2 rotates, the overlapping area of the first electrode element 1 and the second electrode element 2 changes.
In the above example, when the tool to be detected rotates, the first electrode member 1 and the second electrode member 2 move relatively, so that the overlapping (overlapping) area of the first electrode member 1 and the second electrode member 2 relative to each other changes, thereby causing a change in capacitance, which is further detected by the touch chip.
In addition, the second electrode element 2 also rotates relative to the first electrode element 1. That is, the first electrode member 1 and the second electrode member 2 are rotatable, respectively.
In a specific example, the first electrode element 1 rotates and the second electrode element 2 does not rotate, but is in a fixed state, i.e. only one electrode element rotates independently.
With respect to an alternative embodiment, in which only one electrode element is rotated independently, the second electrode element 2 is rotated and the first electrode element 1 is not rotated and is in a fixed state.
In another specific example, the first electrode element 1 rotates clockwise, and the second electrode element 2 rotates counterclockwise, i.e. both oppositely arranged electrode elements rotate, but the rotation directions of the first electrode element 1 and the second electrode element 2 are opposite.
With respect to an alternative embodiment in which the rotation directions of the first electrode member 1 and the second electrode member 2 are opposite, the first electrode member 1 rotates in a counterclockwise direction, and the second electrode member 2 rotates in a clockwise direction.
In some embodiments, the orthographic projection area of the first electrode element 1 is the same as the orthographic projection area of the second electrode element 2. I.e. the first electrode element 1 and the second electrode element 2 are identical in shape,
in a specific example, the shapes of the first electrode element 1 and the second electrode element 2 are arc shapes, sector shapes, semi-circular shapes, square shapes, rectangular shapes, etc., and may be annular sections with 1/2 annular shapes or less than 1/2 annular shapes, which are not listed here.
When the first electrode element 1 and the second electrode element 2 are in the shape of a fan, the area of the fan does not exceed the semicircular area of the same diameter, that is, the diameter of the fan is d, and the area thereof is equal to or smaller than the semicircular area of the diameter d. Similarly, the areas of the first electrode element and the second electrode element which are in other shapes do not exceed the semicircular areas with the same diameter, so that the influence of the parts exceeding the semicircular areas on the relative overlapping areas of the first electrode element 1 and the second electrode element 2 in the rotating process is avoided, the capacitor value detected by each rotating angle of the device is not unique, and the detected rotating angle is inaccurate.
In some embodiments, the orthographic projection area of the first electrode element 1 is larger than the orthographic projection area of the second electrode element 2, i.e. the shape of the first electrode element 1 is different from the shape of the second electrode element 2.
In the above example, when the first electrode element 1 is fixedly arranged, the second electrode element 2 rotates along with the tool to be detected, or when the first electrode element 1 rotates along with the tool to be detected and the second electrode element 2 is fixedly arranged, the touch chip detects the maximum capacitance value, that is, the area of the maximum capacitance value and the area of the second electrode element 2 when the second electrode element 2 is completely overlapped with the first electrode element 1 due to the surface area of the first electrode element 1 being larger than the surface area of the second electrode element 2.
With respect to an alternative embodiment, in which the shape of the first electrode element 1 is different from the shape of the second electrode element 2, the orthographic projection area of the second electrode element 2 is larger than the orthographic projection area of the first electrode element 1.
In the above example, when the first electrode element 1 rotates relative to the second electrode element 2, since the surface area of the first electrode element 1 is smaller than the surface area of the second electrode element 2, the touch chip detects the maximum capacitance value when the second electrode element 2 is completely coincident with the first electrode element 1, that is, the maximum capacitance value and the area of the first electrode element 1.
That is, the shapes of the first electrode element 1 and the second electrode element 2 in the above example are not particularly limited, and the capacitance change amount is detected by the touch chip by changing the relative overlapping area of the first electrode element 1 and the second electrode element 2.
In a specific example, when the shapes of the first electrode element 1 and the second electrode element 2 are different, the shapes of the first electrode element 1 and the second electrode element 2 are any two combinations of a fan shape, an arc shape, a semicircular shape, a square shape, a rectangular shape, and the like.
In some embodiments, the materials of the first electrode element 1 and the second electrode element 2 are conductive electrodes, and are made of conductive materials.
In a specific example, the first electrode element 1 and the second electrode element 2 are made of a metal material.
In a specific example, the conductive material of the first electrode element 1 and the second electrode element 2 is prior art, as the present application adopts the capacitor principle.
In some embodiments, an insulating medium material is provided between the first electrode element 1 and the second electrode element 2.
Since the capacitance is calculated as c=εs/d, ε is the dielectric constant of the medium, S is the area of the relative overlap between the first electrode element 1 and the second electrode element 2, and d is the distance between the two metal plates. The angle detection device is applied to an appliance to be detected, and assuming that two variables epsilon and d are fixed, the capacitance change is determined by the changed relative overlapping area S.
The touch chip commonly used in the market is used, the capacitance is detected based on the CAPSENSE principle, the I/O detection port of the touch chip repeatedly charges and discharges the capacitance, and the charge time required by a certain voltage point is recorded to judge the capacitance value.
In some embodiments, the device further comprises a first rotating part 3 and a second rotating part 4, the first electrode element 1 is arranged on the first rotating part 3, the second electrode element 2 is arranged on the second rotating part 4, and the rotation axis of the first rotating part 3 is relatively parallel to the rotation axis of the second rotating part 4.
In a specific example, the axis of rotation of the first rotating member 3 coincides with the axis of rotation of the first electrode element 1, and the axis of rotation of the first rotating member 3 coincides with the axis of rotation of the second rotating member 4.
In some embodiments, the first rotating member 3 and/or the second rotating member 4 are provided with positioning holes, and the first rotating member 3 and/or the second rotating member 4 are mounted on the rotating shaft 5 of the to-be-detected device through the positioning holes.
In a specific example, the first rotating member 3 and the second rotating member 4 are discs, and a positioning hole is formed in the middle of each disc. Further, the area of the first electrode member 1 and the second electrode member 2 is necessarily smaller than 1/2 of the area of the disk.
In some embodiments, the first electrode element 1 and the second electrode element 2 are designed in sheet form for easy mounting on the first rotating member 3 and the second rotating member 4.
In a specific example, the shapes of the first electrode element 1 and the second electrode element 2 are designed in a fan shape or a semicircular shape or an arc shape according to a disk-shaped rotating member. For example a first electrode element 1 and a second electrode element 2 of semi-circular sheet metal.
In some embodiments, the shape of the first rotating member 3 is the same as or different from the shape of the first electrode element 1, as is the shape of the second rotating member 4.
Specifically, the shapes of the first rotating member 3 and the second rotating member 4 are designed to be a circular shape, a semicircular shape, an annular shape, an arc shape, a fan shape, or the like, which is not exemplified herein. The surface areas of the first rotating part 3 and the second rotating part 4 are not all conductive parts, only the parts where the first electrode element 1 and the second electrode element 2 are positioned are conductive parts, and the rest are insulating parts, so that the other parts of the first electrode element 1 and the second electrode element 2 need to be insulated.
In some embodiments, the first electrode element 1 and the second electrode element 2 having a semicircular shape with respect to the rotation shaft 5 of the tool to be detected are mounted on the first rotation member 3 and/or the second rotation member 4 according to the capacitance change detection tool selection angle, specifically as follows:
assuming a state when the tool to be detected is rotated by 0 °, as shown in fig. 1, the first electrode element 1 of the semicircular shape and the second electrode element 2 of the semicircular shape are completely overlapped at this time, and the capacitance value detected by the touch chip is the maximum value.
Assuming that the angle changes as the tool to be tested rotates from the 0 deg. state, the capacitance gradually decreases.
Assuming a state when the tool to be detected is rotated by 90 °, the overlapping area of the semicircular first electrode element 1 and the semicircular second electrode element 2 is 1/2 of the maximum area, and the capacitance value detected by the touch chip is 1/2 of the maximum value.
Assuming a state when the tool to be detected is rotated 180 °, as shown in fig. 2, the first electrode element 1 of the semicircular shape and the second electrode element 2 of the semicircular shape are not overlapped at this time, and the capacitance value detected by the touch chip is 0, which is the minimum value.
In some embodiments, the first rotating member 3 and the second rotating member 4 are made of insulating medium materials. For example, ceramics (alumina, barium titanate), organic polymers (polyacrylate, polyimide), and the like are not listed here.
In some embodiments, the first electrode element 1 is adhered to the first rotating member 3 and the second electrode element 2 is adhered to the second rotating member 4.
In the above example, since the first electrode element 1 and the second electrode element 2 are disposed at a distance, when the first electrode element 1 and the second electrode element 2 are filled with the air medium before, the first electrode element 1 is attached to the lower surface of the first rotating member 3 as much as possible, and the second electrode element 2 is attached to the lower surface of the second rotating member 4.

In some embodiments, the first electrode element 1 and the second electrode element 2 can be seen as sheet-like, plate-like, film-like metal electrodes.
In some embodiments, the first rotating member 3 and the second rotating member 4 may be provided with a fixing groove, and the fixing groove may be filled with powder made of a conductive material to form an electrode.
