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

[0037] 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.
[0038] Traditional terminal devices usually have a separate microstrip antenna receiving device. When visual assistance is needed to improve GNSS positioning accuracy, a camera device must be installed to provide image information. Therefore, the microstrip antenna and camera device in traditional terminal devices are two independent devices, which makes the terminal device occupy a large space.
[0039] In response to the above problems, the present invention designs a positioning integrated device and its driving equipment. By opening a hole in the microstrip antenna, the camera component is set in the microstrip antenna with the hole, and the distance between the inner edge of the antenna and the edge of the camera component is reasonably controlled, so that the setting of the camera component will not affect the normal operation of the microstrip antenna, thereby enabling the designed positioning integrated device to realize the integration of antenna function and camera function, improve the integration of the positioning integrated device, and reduce the space occupancy rate of the positioning integrated device.
[0040] Based on the above ideas, the present disclosure provides a positioning integrated device, as shown in Figure 1, the positioning integrated device includes a microstrip antenna 1 and a camera assembly 2; a through hole 11 is opened on the microstrip antenna 1, and the camera assembly 2 is arranged in the through hole 11, and the camera assembly 2 is spaced apart from the microstrip antenna 1, and one end of the camera assembly 2 and the bottom end of the microstrip antenna 1 are configured to be connected to an external fixing part A to achieve fixation of the camera assembly 2 and the microstrip antenna 1.
[0041] In the positioning integrated device designed above, the spacing between the camera component 2 and the microstrip antenna 1 indicates that the camera component 2 is not in contact with the microstrip antenna 1, so that the camera component 2 will not affect the normal signal frequency reception and transmission of the microstrip antenna 1. Since the camera component 2 is arranged in the through hole 11 and has no contact with the microstrip antenna 1, in order to fix the camera component 2, it needs to be connected to the external fixing part A (arranged below the microstrip antenna 1) to achieve fixation. In addition, the bottom end of the microstrip antenna 1 is also connected to the external fixing part A to achieve fixation of the microstrip antenna 1. Among them, the camera component 2 refers to a device combination with a camera function, which may include a camera and related devices to assist in camera shooting, such as a focal length adjuster, etc.
[0042] The aforementioned integrated positioning device design utilizes a through-hole in the microstrip antenna, positioning the camera assembly within the through-hole, and securing it with an external fixing portion. This allows the camera assembly to be integrated with the microstrip antenna to form an integrated positioning device. This design allows the integrated positioning device to achieve both antenna positioning and camera functions while reducing its space occupancy and improving its integration. Furthermore, this design provides a separation between the camera assembly and the microstrip antenna, preventing contact between the camera assembly and the microstrip antenna, thereby preventing the camera assembly from interfering with the normal operation of the microstrip antenna and improving the reliability of the positioning device.
[0043] As a possible embodiment, FIG1 is a front schematic diagram of an embodiment of a microstrip antenna 1, and FIG2 is a back schematic diagram of the microstrip antenna 1 of this embodiment. On this basis, the microstrip antenna 1 described above includes a first dielectric plate 110, a first annular metal patch 120, and a second annular metal patch 130. Among them, the first annular metal patch 120 and the second annular metal patch 130 can both be regular circular ring-shaped metal patches. In addition to regular circular ring-shaped metal patches, the first annular metal patch 120 can also be an irregular approximately circular ring-shaped metal patch as shown in FIG1, so that the antenna frequency debugging can be more convenient through the irregular edge protrusions. It should be noted that, in addition to the irregular approximately circular ring shape shown in FIG1, the first annular metal patch 120 can also be an annular metal patch of other irregular shapes.
[0044] The first annular metal patch 120 is disposed on the upper surface of the first dielectric plate 110 , and the second annular metal patch 130 is disposed on the lower surface of the first dielectric plate 110 . The annular hollow portion of the first annular metal patch 120 is opposite to the annular hollow portion of the second annular metal patch 130 .
[0045] A first through hole 111 is provided on the first dielectric plate 110 , and the first through hole 111 connects the annular hollow portion of the first annular metal patch 120 and the annular hollow portion of the second annular metal patch 130 . The camera assembly 2 is disposed in the first through hole 111 and is spaced apart from the first dielectric plate 110 , the first annular metal patch 120 and the second annular metal patch 130 .
[0046] The positioning integrated device designed above generates / receives low-frequency and high-frequency signals through the first annular metal patch 120 and the second annular metal patch 130, and the corresponding through-holes are used through the annular hollow part of the annular metal patch. In this way, the camera component is cleverly integrated into the microstrip antenna, and the installed camera component will not affect the operation of the microstrip antenna, thereby improving the positioning reliability of the positioning integrated device.
[0047] In an optional implementation of this embodiment, the outer ring diameter of the first annular metal patch 120 is larger than the outer ring diameter of the second annular metal patch 130, so that the first annular metal patch 120 generates / receives low-frequency signals, and the designed second annular metal patch 130 generates / receives high-frequency signals.
[0048] Optionally, please continue to refer to Figure 1. The microstrip antenna 1 also includes a plurality of first metal strips 140, which are arranged at equal intervals around the edge of the first dielectric plate 110, and the diameter of the circle formed by the plurality of first metal strips 140 is greater than the maximum diameter of the first annular metal patch 120, that is, the plurality of first metal strips 140 are arranged on the periphery of the first annular metal patch 120, and the plurality of first metal strips 140 do not contact the first annular metal patch 120.
[0049] Based on the above structure, the microstrip antenna 1 further includes a plurality of first metal posts 150. Each first metal post 150 penetrates the first dielectric plate 110. One end of each first metal post 150 is connected to a first metal strip 140, and the other end of each first metal post 150 is connected to the ground terminal of the external fixing portion A. Different first metal posts 150 are connected to different first metal strips 140. This allows the plurality of first metal strips 140 and first metal posts 150 to be configured to increase bandwidth, reduce frequency, and improve impedance matching.
[0050] As a possible implementation, the number of first metal strips 140 and first metal pillars 150 can be 8 evenly distributed as shown in FIG1 , or can be 4 or other even numbers evenly distributed. The specific number can be adaptively adjusted according to the actual application scenario.
[0051] In an optional implementation of this embodiment, please continue to refer to Figure 1. The first dielectric plate 110 is provided with a plurality of first feeding holes 1110, and the plurality of first feeding holes 1110 are provided in the annular hollow portion of the first annular metal patch 120. The first dielectric plate 110 is further provided with a plurality of second feeding holes 1120, and the plurality of second feeding holes 1120 are located in the annular metal region of the first annular metal patch 120, that is, the distance between the plurality of second feeding holes 1120 and the first through hole 111 is greater than the distance between the plurality of first feeding holes 1110 and the first through hole 111.
[0052] The microstrip antenna 1 also includes a plurality of first feeding posts 160, each of which penetrates the first dielectric plate 110. A first end of each first feeding post 160 is connected to a first feeding hole 1110, and a second end of each first feeding post 160 is connected to an external fixing portion A. Each first feeding post 160 is connected to the bottom layer through a first feeding hole 1110 on the first dielectric plate 110, feeding the high-frequency second annular metal patch 130. Furthermore, a plurality of second feeding holes 1120 are configured to feed the first annular metal patch 120 on the first dielectric plate 110. Each first feeding hole 1110 can be formed by a plurality of metal holes, for example, two metal holes, four metal holes, or even eight metal holes as shown in the figure.
[0053] As a possible implementation scheme, the number of first feeding posts 160 and first feeding holes 1110 designed in this scheme can be 4. On this basis, by sequentially loading the feeding network on the external fixing part A, a phase difference of 90° is generated between two adjacent feeding points in the clockwise direction, and it is configured to generate a right-handed circularly polarized wave. The feeding method using four first feeding posts 160 can ensure that the phase center of the antenna is on the vertical center line of the first dielectric plate 110 and the external fixing part A, thereby obtaining a more stable phase center.
[0054] In an optional implementation manner of this embodiment, as a possible implementation manner, multiple first feeding holes 1110 are arranged around the first through hole 111, and the diameter of the circle formed by the multiple first feeding holes 1110 is larger than the diameter of the first through hole 111, so that the first feeding holes 1110 are arranged outside the first through hole 111, thereby avoiding affecting the feeding after the camera component 2 is installed in the hole.
[0055] In an optional implementation manner of this embodiment, it is described above that the camera component 2 is spaced apart from the microstrip antenna 1. As a possible implementation manner, the spacing distance between the camera component 2 and the microstrip antenna 1 can be the distance that produces minimum coupling to the antenna. In this case, the size of the microstrip antenna can be made smaller and will not affect the coupling between the antenna and the camera component.
[0056] In a specific embodiment, when the radius of the first dielectric plate 110 is 110 mm and the camera assembly 2 is disposed within the first through hole 111, the distance between the outer wall of the camera assembly 2 and the first dielectric plate 110 can be any distance between 0.3 mm and 0.6 mm. Alternatively, the distance between the outer wall of the camera assembly 2 and the first dielectric plate 110 can be any distance between 0.3 mm, 0.4 mm, 0.5 mm, and 0.6 mm, and can optionally be 0.5 mm.
[0057] In an alternative implementation of this embodiment, as a possible implementation, the first dielectric plate 110 described above may be an FR4 dielectric passive plate as shown in Figures 1 and 2. As another possible implementation, as shown in Figure 3, the first dielectric plate 110 may be a polytetrafluoroethylene dielectric passive plate.
[0058] In an optional implementation of this embodiment, as another possible implementation, in addition to using air as the dielectric between the dielectric plate and the external fixing portion as described above, the microstrip antenna 1 of this solution can also be a single-layer plastic dielectric plate and directly attached to the external fixing portion A. Specifically, as shown in FIG4 , the microstrip antenna 1 of this solution may include a plastic dielectric plate 170 and a first metal patch 180 , wherein the first metal patch 180 is disposed on the upper surface of the plastic dielectric plate 170 ; the first metal patch 180 includes a connecting portion 1810 and a plurality of blade portions 1820 , wherein the plurality of blade portions 1820 are all connected to the connecting portion 1810 and the plurality of blade portions 1820 are spaced apart; a second through hole 121 is defined in the middle of the connecting portion 1810 ; a third through hole 131 is defined in the plastic dielectric plate 170 , and is opposite to the second through hole 121 ; and the camera assembly 2 is disposed within the second through hole 121 and the third through hole 131 . The plastic dielectric plate 170 is a single-layer passive dielectric plate, and the plurality of blades 1820 and the connecting portion 1810 form a windmill-shaped metal patch. The lower surface of the plastic dielectric plate 170 is configured to be connected to the external fixing portion A. Optionally, the lower surface of the plastic dielectric plate 170 can be bonded, welded, or otherwise connected to the external fixing portion A.
[0059] In the positioning integrated device designed above, the single-layer plastic dielectric plate 170 can effectively reduce the height of the antenna and integrate high and low frequencies on the same plane, making the designed positioning integrated device more miniaturized.
[0060] In an optional implementation of this embodiment, please continue to refer to Figure 4. In order to achieve high and low frequency integration on the same plane, the plastic dielectric plate 170 designed in this solution is provided with a plurality of third feeding holes 1710, and the connecting portion 1810 is provided with a plurality of fourth feeding holes 210. The third feeding holes 1710 and the fourth feeding holes 210 are arranged around the second through hole 121. The plurality of third feeding holes 1710 correspond one-to-one to the plurality of fourth feeding holes 210. The plastic dielectric plate 170 is further provided with a plurality of fifth feeding holes 1720. The plurality of fifth feeding holes 1720 are arranged around the second through hole 121, and the diameter of the circle formed by the third feeding holes 1710 is smaller than the diameter of the circle formed by the fifth feeding holes 1720.
[0061] The microstrip antenna 1 also includes a plurality of second feeding posts 190 and a plurality of third feeding posts 191. Each second feeding post 190 penetrates the plastic dielectric plate 170 through the third feeding hole 1710 and the fourth feeding hole 210, and one end of each second feeding post 190 is connected to the first metal patch 180, and the other end of each second feeding post 190 is connected to the ground end of the external fixing part A; each third feeding post 191 penetrates the plastic dielectric plate 170, and one end of each third feeding post 191 is connected to the fifth feeding hole 1720, and the other end of each third feeding post 191 is connected to the ground end of the external fixing part A.
[0062] Among them, the number of the third feeding hole 1710 , the fourth feeding hole 210 , the fifth feeding hole 1720 , the second feeding post 190 and the third feeding post 191 can all be 4 as shown in FIG. 4 , and their number can be adaptively adjusted according to actual application scenarios.
[0063] The microstrip antenna of the above design generates a high-frequency portion through the plurality of third feeding holes 1710, the fourth feeding holes 210, and the second feeding posts 190, and generates a low-frequency portion through the plurality of fifth feeding holes 1720 and the plurality of third feeding posts 191. The impedance matching problem caused by the through-holes provided between the plastic dielectric plate and the first metal patch can be adjusted by moving the distance between the plurality of second feeding posts 190 and the center of the circle to achieve the best impedance matching.
[0064] In an alternative embodiment of this embodiment, the microstrip antenna 1 further includes a plurality of second metal strips 220 and a plurality of second metal posts 230. The plurality of second metal strips 220 are spaced apart around the edge of the plastic dielectric plate 170. Each second metal post 230 penetrates the plastic dielectric plate 170. One end of each second metal post 230 is connected to a second metal strip 220, and the other end of each second metal post 230 is configured to be connected to the ground terminal of the external fixing portion A. The number of second metal strips 220 and second metal posts 230 may also be four, as shown in FIG. This number can be adjusted adaptively based on the actual application scenario.
[0065] In the microstrip antenna designed above, this solution uses multiple second metal strips and multiple second metal columns on the outermost side of the microstrip antenna to connect to the ground, thereby achieving the effects of increasing bandwidth, reducing frequency, and improving impedance matching.
