This application claims the priority benefit of Chinese Patent Application Serial Number 202121047024.4, filed on May 17, 2021, the full disclosure of which is incorporated herein by reference.
The present disclosure relates to the technical field of directional positioning, particularly to a geomagnetic positioning device.
In the prior art, a positioning device that detects geomagnetism to calculate an azimuth deviation angle could take a deviation angle between the device and the environment as a reference to control the actual deviation angle of the positioning device after measuring a deviation angle of the device relative to the environmental geomagnetism by the geomagnetic sensor in the positioning device.
Such devices are mostly used for angular positioning in horizontal direction. For further angular positioning in both horizontal and vertical directions, massive and complicated positioning calculations are necessary. However, such further calculations would easy to cause positioning errors.
The embodiments of the present disclosure provide a geomagnetic positioning device tended to solve the problem of positioning errors caused by massive and complicated positioning calculations at the moment.
The present disclosure provides a geomagnetic positioning device, comprising a base assembly and a connecting assembly. The base assembly comprises a control component, a driving component, and a first geomagnetic component. The control component is electrically connected with the driving component and the first geomagnetic component. The connecting assembly is disposed at the driving component and comprises a second geomagnetic component. Wherein the control component obtains the deviation angle of the second geomagnetic component relative to the first geomagnetic component.
The present disclosure provides a geomagnetic positioning device. According to the reading difference to the geomagnetism between the first geomagnetic component of the base assembly and the second geomagnetic component of the connecting assembly, a relative angle between the base assembly and the connecting assembly and an absolute angle of the two can be calculated, so that relevant computing requirements can be lowered to realize precise control for horizontal and vertical rotation.
It should be understood, however, that this summary may not contain all aspects and embodiments of the present disclosure, that this summary is not meant to be limiting or restrictive in any manner, and that the disclosure as disclosed herein will be understood by one of ordinary skill in the art to encompass obvious improvements and modifications thereto.
The features of the exemplary embodiments believed to be novel and the elements and/or the steps characteristic of the exemplary embodiments are set forth with particularity in the appended claims. The Figures are for illustration purposes only and are not drawn to scale. The exemplary embodiments, both as to organization and method of operation, may best be understood by reference to the detailed description which follows taken in conjunction with the accompanying drawings in which:
The present disclosure will now be described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the disclosure are shown. This present disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.
Certain terms are used throughout the description and following claims to refer to particular components. As one skilled in the art will appreciate, manufacturers may refer to a component by different names. This document does not intend to distinguish between components that differ in name but function. In the following description and in the claims, the terms “include/including” and “comprise/comprising” are used in an open-ended fashion, and thus should be interpreted as “including but not limited to”. “Substantial/substantially” means, within an acceptable error range, the person skilled in the art may solve the technical problem in a certain error range to achieve the basic technical effect.
The following description is of the best-contemplated mode of carrying out the disclosure. This description is made for the purpose of illustration of the general principles of the disclosure and should not be taken in a limiting sense. The scope of the disclosure is best determined by reference to the appended claims.
Moreover, the terms “include”, “contain”, and any variation thereof are intended to cover a non-exclusive inclusion. Therefore, a process, method, object, or device that includes a series of elements not only includes these elements, but also includes other elements not specified expressly, or may include inherent elements of the process, method, object, or device. If no more limitations are made, an element limited by “include a/an . . . ” does not exclude other same elements existing in the process, the method, the article, or the device which includes the element.
In this embodiment, the first driving component 114 comprises a first driving member 1141, a first gear group 1142, a second driving member 1143, and a second gear group 1144. The first gear group 1142 is linked to and between the first driving member 1141 and the central shaft 115. The first driving member 1141 and the first gear group 1142 are oppositely disposed at one side of the central shaft 115. The second driving member 1143 and the second gear group 1144 are oppositely disposed at the other side of the central shaft 115. Wherein, the second gear group 1144 is linked to and between the second driving member 1143, and the central shaft 115. The first driving member 1141 drives the first gear group 1142 to drive the central shaft 115 to rotate horizontally in the first direction. The second driving member 1143 drives the second gear group 1144 to drive the central shaft 115 to rotate horizontally in the second direction. The first direction is opposite to the second direction. Besides, both the first gear group 1142 and the second gear group 1144 comprise a driving gear 1145 and a central shaft gear 1146. The first driving member 1141 and the second driving member 1143 are linked to the driving gear 1145. The driving gear 1145 is linked to the central shaft gear 1146, which drives the central shaft 115 to rotate.
In this embodiment, the geomagnetic positioning device 1 can be considered as a positioning control device for other controlled devices, such as a camera lens. The first geomagnetic component 113 of the base assembly 11 could detect the values of X, Y, and Z relative to the geomagnetic deflection, and the second geomagnetic component 131 of the connecting assembly 13 could detect the values of X, Y, and Z relative to the geomagnetic deflection. When the above X, Y, and Z values are taken into account for angle calculation, the control component 111 would control the driving component 112 according to the calculated deviation angle. Thus, the relative angle of the connecting assembly 13 relative to the base assembly 11 can be adjusted.
Referring to
In summary, embodiments of the present disclosure provide a geomagnetic positioning device. According to the reading difference to the geomagnetism between the first geomagnetic component of the base assembly and the second geomagnetic component of the connecting assembly, a relative angle between the base assembly and the connecting assembly and an absolute angle of the two can be calculated, so that relevant computing requirements can be lowered to realize precise control for horizontal and vertical rotation.
It is to be understood that the term “comprises”, “comprising”, or any other variants thereof, is intended to encompass a non-exclusive inclusion, such that a process, method, article, or device of a series of elements not only comprise those elements but further comprises other elements that are not explicitly listed, or elements that are inherent to such a process, method, article, or device. An element defined by the phrase “comprising a . . . ” does not exclude the presence of the same element in the process, method, article, or device that comprises the element.
Although the present disclosure has been explained in relation to its preferred embodiment, it does not intend to limit the present disclosure. It will be apparent to those skilled in the art having regard to this present disclosure that other modifications of the exemplary embodiments beyond those embodiments specifically described here may be made without departing from the spirit of the disclosure. Accordingly, such modifications are considered within the scope of the disclosure as limited solely by the appended claims.
