[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims priority to Chinese patent application number 2024100123344, filed with the Chinese Patent Office on January 3, 2024, entitled “Positioning integrated device and driving equipment thereof,” the entire contents of which are incorporated by reference into this disclosure. Technical Field

[0003] The present disclosure relates to the field of positioning technology, and in particular to a positioning integrated device and a driving device thereof. Background Art

[0004] To improve Global Navigation Satellite System (GNSS) positioning accuracy in complex environments, sensors such as cameras are used in GNSS receivers for surveying and mapping, automotive navigation, and other applications to assist with GNSS positioning. This integration of photogrammetry and satellite navigation technologies enhances the usability of navigation and positioning services in complex scenarios.

[0005] The GNSS positioning antenna used in traditional terminal devices is usually a separate receiving device. When visual assistance is needed to improve the GNSS positioning accuracy, a camera device needs to be installed to provide image information. Therefore, the positioning antenna and camera device in traditional terminal devices are two independent devices, which makes the terminal device occupy a large space. Summary of the Invention

[0006] The purpose of the embodiments of the present disclosure is to provide a positioning integrated device and a driving device thereof, so as to solve the problem that the positioning antenna and the camera device in the current traditional terminal device are two independent devices, resulting in a large space occupation of the terminal device.

[0007] Optionally, the present invention provides a positioning integrated device, which includes a helical antenna and a camera assembly; the helical antenna includes a helical antenna body and a feed board, the helical antenna body is arranged around the feed board, and a accommodating space with an opening is formed between the feed board and the surrounding helical antenna body; the camera assembly includes a camera module, the camera assembly is arranged in the accommodating space, and the camera assembly is connected to the feed board, and the field of view of the camera module is toward the opening of the accommodating space.

[0008] In the positioning integrated device designed above, the helical antenna is arranged on the feed board around the helical antenna body to form an accommodation space with an opening facing the end. On this basis, this solution arranges the camera component in the accommodation space and fixes the camera component to the feed board. The field of view of the camera module is toward the end of the opening. On the basis of achieving the effects of antenna positioning and visual assistance, the camera component is integrated into the internal space of the helical antenna, so that the designed positioning integrated device is only the size of the helical antenna, which greatly shortens the space occupancy rate of the terminal device and makes the terminal device miniaturized.

[0009] In an optional embodiment, the camera assembly further includes a support column; one end of the support column is connected to the feed board, and the other end of the support column is connected to the camera module. In this embodiment, the support column supports and elevates the camera module, thereby ensuring that the camera module's field of view is not obstructed by the storage space, thereby improving the imaging effect of the positioning integrated device.

[0010] In an optional embodiment, the inner diameter of the accommodating space is larger than the diameter of the support column; and the central axis of the accommodating space, the central axis of the support column, and the central axis of the camera module coincide. In this embodiment, by aligning the central axis of the helical antenna, the central axis of the support column, and the central axis of the camera module, and by making the inner diameter of the accommodating space larger than the diameter of the support column, the camera assembly is positioned at the center of the accommodating space, and the camera assembly does not contact the accommodating space (i.e., the main body of the helical antenna), thereby preventing the camera assembly from contacting the main body of the helical antenna and affecting the antenna's function, thereby improving the reliability of the integrated positioning device.

[0011] In an optional embodiment, the camera assembly further includes an adjuster disposed between the support column and the camera module, and configured to adjust the focal length of the camera module. This embodiment adjusts the focal length of the camera module via the adjuster, thereby improving the camera performance of the positioning integrated device.

[0012] In an alternative embodiment, the total height of the support column, adjuster, and camera module is equal to the height of the accommodating space. This embodiment designs the total height of the support column, adjuster, and camera module to be equal to the height of the accommodating space, so that the camera module is flush with the open end of the accommodating space, thereby ensuring that the camera module's field of view is not affected and improving the camera module's imaging effect.

[0013] In an optional embodiment, the support column is a hollow column. This embodiment design of the support column as a hollow column allows the camera module's wiring harness to extend to the outside through the hollow column and the feed board, thereby improving the integration of the positioning integrated device. At the same time, the wiring harness of the antenna and the wiring harness of the camera assembly in the positioning integrated device can be extended simultaneously on the same device, thereby improving the installation portability of the device.

[0014] In an optional embodiment, the camera module is connected to the feed board, and the height of the accommodating space is consistent with the height of the camera module.

[0015] In an optional embodiment, the camera module is connected to the feed board, and the height of the accommodating space is greater than the height of the camera module.

[0016] In an optional embodiment, a helical antenna body includes a substrate and a radiator attached to a surface of the substrate. The substrate is arranged around a feed plate to form a cylindrical shape, and a looped metal wire is disposed on the top of the substrate. The radiator includes at least one group of helical antenna units, which are arranged in a rotational direction around the substrate to form a helical antenna. Each group of helical antenna units includes a first helical antenna and a second helical antenna, the first helical antenna being longer than the second helical antenna, the first helical antenna being used to excite low frequencies, and the second helical antenna being used to excite high frequencies. A feed network is disposed on the surface opposite the feed plate where it is connected to the helical antenna body. The feed network includes multiple feeding points. The first end of each first helical antenna is connected to the looped metal wire, and the second end of each first helical antenna is connected to the second end of the corresponding second helical antenna, and then connected to the corresponding feeding point of the feed network. Different helical antenna units are connected to different feeding points. This embodiment achieves low and high frequency reception by using helical antennas of different lengths, thereby enabling multi-band reception of the helical antenna.

[0017] Optionally, the present invention provides a driving device, which includes the positioning integrated device of any of the above optional embodiments.

[0018] The driving device designed as above includes the positioning integrated device of any of the above optional embodiments. Therefore, when the positioning integrated device is installed, the driving device occupies less space, thereby improving the space utilization rate of the driving device.

[0034] To improve Global Navigation Satellite System (GNSS) positioning accuracy in complex environments, sensors such as cameras are used in GNSS receivers for surveying and mapping, automotive navigation, and other applications to assist with GNSS positioning. This integration of photogrammetry and satellite navigation technologies enhances the usability of navigation and positioning services in complex scenarios.

[0035] The GNSS positioning antenna used in traditional terminal devices is usually a separate receiving device. When visual assistance is needed to improve the GNSS positioning accuracy, a camera device needs to be installed to provide image information. Therefore, the positioning antenna and camera device in traditional terminal devices are two independent devices, which makes the terminal device occupy a large space.

[0036] In response to the above problems, the present invention designs a positioning integrated device and its driving equipment, which utilizes the internal space of the spiral antenna to integrate the camera component into the internal space of the spiral antenna, so that the designed positioning integrated device is only the size of the spiral antenna when realizing antenna positioning and visual assistance, greatly shortening the space occupancy rate of the terminal device and making the terminal device miniaturized; moreover, the wiring harness of the antenna and the wiring harness of the camera component in the positioning integrated device designed in this scheme can be extended on one device at the same time, thereby improving the installation portability of the equipment.

[0037] Based on the above ideas, the present disclosure provides a positioning integrated device, as shown in FIG1 , which includes a helical antenna 10 and a camera assembly 20. The helical antenna 10 includes a helical antenna body 110 and a feed plate 120. The helical antenna body 110 is arranged around the feed plate 120. A receiving space 130 with an opening 110A is formed between the feed plate 120 and the surrounding helical antenna body 110. The camera assembly 20 includes a camera module 210. The camera assembly 20 is arranged in the receiving space 130, and the camera assembly 20 is connected to the feed plate 120. The field of view of the camera module 210 is toward the opening 110A. The helical antenna 10 can be in the form of any current helical antenna, such as a four-arm helical antenna, etc. Its working principle is consistent with the working principle of the current helical antenna and will not be elaborated herein. The camera module 210 refers to a module with a camera or photo function, such as a micro camera or a pinhole camera. Of course, in addition to devices with camera or photo functions, the camera module 210 may also include a storage device for storing data captured by the camera module 210.

[0038] In the positioning integrated device designed above, the helical antenna is arranged on the feed board around the helical antenna body to form an accommodation space with an opening facing the end. On this basis, this solution arranges the camera component in the accommodation space and fixes the camera component to the feed board. The field of view of the camera module is toward the end of the opening. On the basis of achieving the effects of antenna positioning and visual assistance, the camera component is integrated into the internal space of the helical antenna, so that the designed positioning integrated device is only the size of the helical antenna, which greatly shortens the space occupancy rate of the terminal device and makes the terminal device miniaturized.

[0039] In an optional implementation of this embodiment, as a possible implementation, as shown in Figure 1, the camera assembly 20 may only include a camera module 210, and the height of the accommodating space 130 is greater than the height of the camera module 210. In this solution, the camera module 210 is set in the accommodating space 130, and the camera module 210 is directly connected to the feeding board 120. In this case, the designed positioning integrated device can use the optical effects of the camera module 210 to obtain the field of view.

[0040] In an alternative implementation of this embodiment, as another possible implementation, as shown in FIG2 , the camera assembly 20 also only includes a camera module 210. In this case, the camera module 210 is disposed in the accommodating space 130, and the camera module 210 is directly connected to the feed board 120. Furthermore, in order to obtain a wider camera field of view, the cross-section of the helical antenna body 110 is reduced, the inner diameter of the accommodating space 130 formed by the helical antenna body 110 is increased, and the height of the accommodating space 130 is equal to the height of the camera module 210, thereby enabling the camera module 210 to have a wider camera field of view.

[0041] In an optional implementation of this embodiment, since the formed accommodating space 130 generally has a certain depth, as another possible implementation, as shown in Figure 3, the camera assembly 20 designed in this scheme may also include a support column 220, one end of the support column 220 is connected to the feeding board 120, and the other end of the support column 220 is connected to the camera module 210, so that the camera module 210 is supported by the support column 220, and the camera module 20 is raised to a position close to the opening 110A of the accommodating space 130, so that the camera field of view of the camera module 210 will not be blocked by the accommodating space 130, thereby improving the camera effect of the camera assembly 20.

[0042] As a possible implementation, referring to FIG3 , the inner diameter of the accommodation space 130 of this design is larger than the diameter of the support column 220, and the central axis of the accommodation space 130 coincides with the central axis of the support column 220 and the central axis of the camera module 210. This allows the support column 220 to be entirely accommodated within the accommodation space 130 and located at the center of the accommodation space 130. Furthermore, since the inner diameter of the accommodation space 130 is larger than the inner diameter of the support column 220, the support column 220 and the inner wall of the accommodation space 130 (i.e., the helical antenna body 110) will not contact each other, thereby preventing the support column 220 and the camera module 210 from contacting the helical antenna body 110 and thus affecting the function of the helical antenna. It should be noted that, if it is determined that the camera assembly 20 is in contact with the helical antenna body 110 without affecting the function of the helical antenna, the camera assembly 20 in the designed positioning integrated device can contact the helical antenna body 110.

[0043] In an optional implementation of this embodiment, as shown in FIG3 , the camera assembly 20 may further include an adjuster 230 , which is disposed between the support column 220 and the camera module 210 , and is used to adjust the focal length of the camera module 210 .

[0044] As a possible implementation, please continue to refer to Figure 4. The total height of the support column 220, the adjuster 230 and the camera module 210 designed in this scheme is equal to the height of the accommodating space, so that the height of the camera module 210 is basically flush with the height of the accommodating space 130, and the camera module 210 will not be blocked by the inner wall of the accommodating space 130, thereby improving the camera effect.

[0045] In an optional implementation of this embodiment, as shown in Figure 4, the support column 220 designed in this scheme is a hollow column, so that the wiring harness of the camera module 210 can pass through the space of the hollow support column 220, and then through the center of the feed board 120, and extend to the outside, thereby connecting to other interfaces. In this way, the wiring harness of the helical antenna and the wiring harness of the camera assembly can be extended on the same device at the same time, thereby improving the installation portability of the equipment.

[0046] In an optional implementation manner of this embodiment, please refer to Figures 1 to 3. The helical antenna body 110 described above may include a substrate 1110 and a radiator 1120 attached to the surface of the substrate 1110, wherein the substrate 1110 is arranged around the feeding plate 120 to form a cylindrical shape, wherein the radiator 1120 is attached to the outer surface of the cylindrical body 1110, and the inner surface of the substrate 1110 and the feeding plate 120 form the accommodating space 130. A ring-shaped metal wire 1130 is provided at the top of the substrate, so that the designed ring-shaped metal wire 1130 is connected to the helical antenna that excites the low frequency, thereby improving the positioning accuracy of the antenna.

[0047] Radiator 1120 includes at least one group of helical antenna elements 11210, which are arranged in a rotational pattern around a substrate in the same direction to form a helical antenna. Each group of helical antenna elements 11210 includes a first helical antenna 11210A and a second helical antenna 11210B. The first helical antenna 11210A is longer than the second helical antenna 11210B. The first helical antenna 11210A is used to excite low frequencies, while the second helical antenna 11210B is used to excite high frequencies. Helical antenna elements 11210 may be arranged in one or more groups, with the latter comprising two, four, or more groups.

[0048] A feeding network 1210 (not shown) is provided on the opposite surface where the feeding board 120 is connected to the helical antenna body 110. The feeding network 1210 includes a plurality of feeding points 1210A. The first ends of the first helical antennas 11210A are connected to the annular metal wire 1130. The second ends of the first helical antennas 11210A are connected to the second ends of the corresponding second helical antennas 11210B and then to the feeding points 1210A corresponding to the feeding network 1210. Different helical antenna units 11210 are connected to different feeding points 1210A.

[0049] The substrate 1110 described above can be specifically made of a flexible printed circuit (FPC). This FPC material offers a compact size and excellent temperature resistance, meeting the specialized requirements of automotive electronics. Furthermore, FPC antennas can be as thin as a few tenths of a millimeter, providing flexibility and reliability that can withstand environmental vibrations and temperature fluctuations. By printing metal wire onto the FPC and then winding it into a cylindrical shape, the antenna structure is created, significantly reducing both cost and manufacturing complexity.

[0050] The feed plate 120 described above can be specifically a metal plate. The feed plate 120 can be specifically made of printed circuit board (PCB) material. The surface of the feed plate 120 that contacts the substrate 1110 is a metal surface (e.g., copper, aluminum, silver, or other materials), and is provided with multiple feeding points. The feed plate 120 can also be specifically disc-shaped, and its diameter can be slightly larger than the diameter of the upper and lower bottom surfaces of the cylinder formed by winding the substrate.

[0051] In an optional implementation of this embodiment, as a specific implementation, the helical antenna units 11210 described above may be specifically four groups. In this case, the helical antenna designed in this solution is a four-arm helical antenna. Each group of helical antenna units 11210 has the same structure. The four groups of helical antenna units 11210 may be evenly distributed at 90° intervals along the center of the cylindrical surface formed by the substrate 1110. Each group of helical antenna units 11210 includes a longer first helical antenna 11210A and a shorter second helical antenna 11210B, thereby achieving two operating frequencies, one low and one high, for radiating and receiving low-frequency and high-frequency electromagnetic waves. The helical antenna designed in this solution can adjust the operating frequency band of the helical antenna by adjusting the length of the first helical antenna 11210A and the second helical antenna 11210B, thereby enabling the helical antenna to operate within the frequency band corresponding to the GNSS system.

[0052] When four helical antenna units 11210 are arranged, this design also provides four feed points. In the feed network of feed board 120, each feed point has a 90° phase difference, decreasing in phase around the center of the circle to satisfy a right-handed spiral direction, thereby generating a right-handed circularly polarized wave. An antenna with four feed points has a more stable phase center, resulting in higher GNSS navigation positioning accuracy.

[0053] In addition, it should be noted that the helical antenna units 11210 of this solution can also be in other quantities, such as two symmetrically arranged groups of helical antenna units, that is, evenly spaced at 180° intervals; or eight symmetrically arranged groups of helical antenna units, that is, evenly spaced at 45° intervals. The specific form can be adaptively adjusted according to the actual application scenario. In addition, because the helical antenna radiates backward, the first helical antenna 11210A and the second helical antenna 11210B in the helical antenna units 11210 designed in this solution are both wound in a left-handed manner.

[0054] The present disclosure also provides a driving device, as shown in FIG5 , the driving device 2 may include the positioning integrated device 1 described in any of the above optional embodiments, so that the positioning accuracy of the driving device can be improved after the driving device 2 is installed with the designed positioning integrated device 1.

[0055] The driving device designed as above includes the positioning integrated device of any of the optional embodiments described above. Therefore, when the positioning integrated device is installed, the driving device occupies less space, thereby improving the space utilization rate of the driving device.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure, rather than to limit them. Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present disclosure, and they should all be included in the scope of the claims and specification of the present disclosure. In particular, as long as there is no structural conflict, the various technical features mentioned in the various embodiments can be combined in any way. The present disclosure is not limited to the specific embodiments disclosed herein, but includes all technical solutions that fall within the scope of the claims. Industrial Applicability
