Description

Technical Field

[0001] This application relates to the field of GNSS technology, and more specifically, to a GNSS receiver. Background Technology

[0002] A GNSS receiver is a surveying and mapping device based on the Global Navigation Satellite System. Currently, GNSS receivers are widely used in various fields. For example, they are indispensable tools in navigation, aerospace, and geographic surveying. They are also widely used in agriculture, transportation, environmental monitoring, and earthquake early warning systems.

[0003] The development of GNSS receiver battery technology must take into account many factors, such as measurement accuracy, weight, and durability. In addition, the ease of manufacturing GNSS receivers is also a key consideration.

[0004] To provide a wide field of view, GNSS receivers are equipped with multiple cameras, each mounted individually on a bracket. However, since the lens lengths of the different cameras vary, multiple brackets are required. This increases the assembly complexity and reduces the ease of manufacturing.

[0005] Therefore, in the development of GNSS receivers, how to improve the ease of processing and manufacturing GNSS receivers is a technical problem that urgently needs to be solved in GNSS receiver technology. Utility Model Content

[0006] This application provides a GNSS receiver that improves the ease of manufacturing GNSS receivers.

[0007] In a first aspect, embodiments of this application provide a GNSS receiver, including a housing and a camera module. The housing has a camera window; the camera module is disposed inside the housing and correspondingly disposed to the camera window; wherein, the camera module includes a bracket and a camera, the bracket is connected to the housing, the bracket has a first mounting surface facing the camera window and a second mounting surface facing away from the camera window, and the camera is connected to the first mounting surface or the camera is connected to the second mounting surface.

[0008] In the above technical solution, by setting a first mounting surface facing the camera window and a second mounting surface away from the camera window on the bracket, different mounting surfaces can be selected for installation according to different lens lengths. This allows one bracket to be compatible with two or more types of cameras, thereby reducing the number of bracket types. Consequently, the number of parts that need to be assembled during the assembly of the GNSS receiver is reduced, thus lowering the assembly difficulty and improving the convenience of GNSS receiver manufacturing.

[0009] In some embodiments, the bracket is detachably mounted within the housing, and / or the camera is detachably mounted on the bracket.

[0010] In the above technical solution, by detachably mounting the bracket inside the housing and / or detachably mounting the camera to the bracket, the camera module can be quickly replaced and repaired by disassembling either the bracket or the camera when it is damaged, thus improving repair efficiency. Especially when both the bracket and the camera are detachably mounted to the bracket, it facilitates replacement based on the damaged part of the camera module, reducing repair costs.

[0011] In some embodiments, the camera has a peripheral portion and a lens portion, the peripheral portion being connected to the first mounting surface, or the peripheral portion being connected to the second mounting surface.

[0012] In the above technical solution, by connecting the peripheral part to the first mounting surface, or by connecting the peripheral part to the first mounting surface, the connection point is far away from the lens part when the camera is connected to the bracket. This reduces the risk of the lens part being damaged by collision during the assembly or disassembly of the camera, and improves the production yield of GNSS receivers.

[0013] In some embodiments, the second mounting surface is provided with a first through hole, which penetrates both the first mounting surface and the second mounting surface. When the peripheral portion is connected to the second mounting surface, the lens portion passes through the first through hole, and the peripheral portion abuts against the second mounting surface.

[0014] In the above technical solution, by providing a first through hole that extends through to the first mounting surface on the second mounting surface, and allowing the lens to pass through the first through hole, on the one hand, the first through hole can serve as a clearance structure, reducing the risk of the bracket interfering with the lens when the lens is connected to the second mounting surface; on the other hand, by allowing part of the lens to be located within the first through hole, the bracket can reduce the risk of damage to the lens from external impacts during the installation or removal of the camera module.

[0015] In some embodiments, the peripheral portion is provided with a second through hole, and the first mounting surface is provided with a first threaded hole, the first threaded hole penetrating the first mounting surface and the second mounting surface; the GNSS receiver further includes a first connector, the first connector passing through the second through hole and connected to the first threaded hole, so as to fix the camera to the bracket.

[0016] In the above technical solution, the connection between the peripheral part and the bracket is made more stable by the first connector passing through the second through hole and connecting to the first threaded hole, thereby improving the reliability of the camera installation. At the same time, by having the first threaded hole pass through the first mounting surface and the second mounting surface, the camera can be installed through the first threaded hole when it is installed on the first mounting surface or the second mounting surface via the first connector. On the one hand, this reduces the assembly difficulty and improves the convenience of manufacturing the GNSS receiver. On the other hand, compared with the case where threaded holes are set on the first mounting surface and the second mounting surface respectively, the processing steps of the bracket are reduced, the processing difficulty of the bracket is reduced, and thus the convenience of manufacturing the GNSS receiver is improved.

[0017] In some embodiments, there are multiple first connectors, and the multiple first connectors are arranged at circumferential intervals along the lens portion.

[0018] In the above technical solution, by arranging multiple first connectors at circumferential intervals along the antenna, the connection between the camera and the bracket is made more stable, thereby improving the reliability of the camera installation.

[0019] In some embodiments, the bracket includes a base plate and an upright plate. The base plate is connected to the inner surface of the housing on one side in its thickness direction, and the upright plate is disposed on the other side of the base plate in its thickness direction. The thickness direction of the upright plate is perpendicular to the thickness direction of the base plate, and the first mounting surface and the second mounting surface are respectively provided on both sides of the upright plate in its thickness direction.

[0020] In the above technical solution, by connecting the base plate to the inner surface of the shell on one side of its thickness direction and setting the upright plate on the other side of the base plate in its thickness direction, the base plate can increase the area of ​​connection between the support and the shell compared to the case where the upright plate is directly connected to the inner surface of the shell, thereby improving the connection strength between the support and the shell.

[0021] In some embodiments, a limiting post is provided on the inner surface of the housing, and a limiting hole corresponding to the limiting post is provided on the bottom plate. The limiting post cooperates with the limiting hole to restrict the movement of the bracket relative to the housing.

[0022] In the above technical solution, by setting a limiting post on the inner surface of the housing and setting a limiting hole corresponding to the limiting post on the bottom plate, the bracket can be positioned by the limiting post and the limiting hole during the assembly of the camera module. On the one hand, this makes the positioning and installation of the bracket and the housing more accurate; on the other hand, it facilitates the positioning and installation of the bracket during the assembly process, thereby improving the convenience of GNSS receiver manufacturing.

[0023] In some embodiments, there are multiple camera modules, camera windows, and limiting posts. The multiple limiting posts are configured into multiple groups, and the multiple camera modules, multiple camera windows, and multiple groups of limiting posts correspond one-to-one. The base plate is provided with multiple limiting holes, and each limiting hole is configured to correspond to at least one limiting post.

[0024] In the above technical solution, by setting multiple limiting holes on the base plate, and ensuring that each limiting hole corresponds to at least one limiting post, the limiting holes on the bracket can cooperate with different sets of limiting posts corresponding to different camera windows to limit the installation of the camera. This allows one bracket to be adapted to the installation of cameras with different camera windows, further reducing the number of bracket types. Consequently, the number of parts that need to be assembled during the assembly of the GNSS receiver is reduced, thereby reducing the assembly difficulty and improving the convenience of GNSS receiver manufacturing.

[0025] In some embodiments, the base plate is provided with a third through hole, and the inner surface of the housing is provided with a second threaded hole; the GNSS receiver further includes a second connector, which passes through the third through hole and is connected to the second threaded hole to fix the bracket to the housing.

[0026] In the above technical solution, the second connector passes through the third through hole and is connected to the second threaded hole, which makes the connection between the base plate and the shell more stable, thereby improving the reliability of the bracket installation.

[0038] Please refer to Figures 1-5 , Figure 1This is a partial structural cross-sectional view of a GNSS receiver 100 provided in some embodiments of this application. Figure 2 This is a partial structural cross-sectional view of the housing 10 provided in some embodiments of this application. Figure 3 This is a schematic diagram of the structure of a camera module 20 with the camera 22 disposed on the first mounting surface 211, provided in some embodiments of this application. Figure 4 This is a schematic diagram of the structure of a camera module 20 with the camera 22 disposed on the second mounting surface 212, provided in some embodiments of this application. Figure 5 This is a schematic diagram of the structure of the bracket 21 provided in some embodiments of this application. Embodiments of this application provide a GNSS receiver 100, including a housing 10 and a camera module 20. The housing 10 has a camera window 11; the camera module 20 is disposed inside the housing 10 and correspondingly disposed to the camera window 11; wherein, the camera module 20 includes a bracket 21 and a camera 22, the bracket 21 is connected to the housing 10, the bracket 21 has a first mounting surface 211 facing the camera window 11 and a second mounting surface 212 facing away from the camera window 11, the camera 22 is connected to the first mounting surface 211, or the camera 22 is connected to the second mounting surface 212.

[0039] In some embodiments, the GNSS receiver 100 (Global Navigation Satellite System, or GNSS for short) can combine satellite navigation and photogrammetry technologies to obtain high-precision three-dimensional coordinates. It receives signals transmitted by multiple satellites, processes and analyzes the signals, and then uses the measurement data to calculate the position for purposes such as precision geodetic surveying and precision engineering surveying.

[0040] The housing 10 is a shell-like structure in the GNSS receiver 100 used to house other structural components (such as the camera 22 assembly, motherboard, etc.) and to provide a stable operating environment for these components. For example, the GNSS receiver 100 may include a motherboard that integrates various sensors and functional modules for processing satellite signals and photographic information to achieve functions such as positioning, navigation, and mapping.

[0041] In some embodiments, the housing 10 may include a first housing 10 and a second housing, which are connected to form a cavity for accommodating other structural components. Exemplarily, the first housing and the second housing may be connected by bolts, snap-fit, adhesive, or other means.

[0042] The camera window 11 is an opening provided on the housing 10 for the camera 22 to capture images of the external environment. Exemplarily, a protective plate may be provided inside the camera window 11 to isolate the interior of the housing 10 from the outside. Understandably, the protective plate may be made of a transparent material.

[0043] In some embodiments, the first housing is located below the second housing, and the camera windows 11 are all located in the first housing.

[0044] The camera module 20 is a mechanism installed inside the housing 10 for acquiring external images.

[0045] The camera module 20 and the camera window 11 are set to correspond, meaning that the camera 22 in the camera module 20 can take pictures through the camera window 11.

[0046] The camera 22 is a component in the camera module 20 used to acquire images. Understandably, the lens portion 222 of the camera 22 is positioned facing the camera window 11.

[0047] The bracket 21 is a connector in the camera module 20 used to connect the camera 22 and the housing 10.

[0048] The first mounting surface 211 is one side of the bracket 21 facing the camera window 11, and the second mounting surface 212 is one side of the bracket 21 facing away from the camera window 11. Understandably, the first mounting surface 211 and the second mounting surface 212 are parallel to each other.

[0049] In some embodiments, the bracket 21 includes a vertical plate 21A, with a first mounting surface 211 and a second mounting surface 212 on opposite sides in the thickness direction of the vertical plate 21A.

[0050] Understandably, given a fixed mounting position of the bracket 21 relative to the housing 10, the second mounting surface 212 is further away from the camera window 11 than the first mounting surface 211. This allows the distance between the camera window 11 and the second mounting surface 212 to be adapted to a longer camera 22, and the distance between the camera window 11 and the first mounting surface 211 to be adapted to a shorter camera 22. This enables one bracket 21 to accommodate the installation requirements of at least two types of cameras 22, thus requiring fewer types of brackets 21 when assembling the cameras 22.

[0051] In this embodiment, by providing a first mounting surface 211 facing the camera window 11 and a second mounting surface 212 facing away from the camera window 11 on the bracket 21, different mounting surfaces can be selected for installation according to the different lengths of the lens section 222. This allows one bracket 21 to be compatible with two or more types of cameras 22, thereby reducing the number of bracket types. Consequently, the number of parts that need to be assembled during the assembly of the GNSS receiver 100 is reduced, thus lowering the assembly difficulty and improving the ease of manufacturing the GNSS receiver 100.

[0052] Please refer to Figures 3-5According to some embodiments of this application, the bracket 21 is detachably mounted inside the housing 10, and / or the camera 22 is detachably mounted on the bracket 21.

[0053] For example, the bracket 21 can be detachably mounted inside the housing 10 by means of screws, snap-fits, or other methods. The camera 22 can be detachably mounted to the bracket 21 by means of screws, snap-fits, or other methods.

[0054] In this embodiment, by detachably mounting the bracket 21 inside the housing 10 and / or detachably mounting the camera 22 to the bracket 21, the camera module 20 can be quickly replaced and repaired by disassembling either the bracket 21 or the camera 22 when it is damaged, thus improving repair efficiency. Especially when both the bracket 21 and the camera 22 are detachably mounted to the bracket 21, it is convenient to replace the damaged part of the camera module 20, reducing repair costs.

[0055] Please refer to Figures 3-5 According to some embodiments of this application, the camera 22 has a peripheral portion 221 and a lens portion 222, wherein the peripheral portion 221 is connected to a first mounting surface 211 or the peripheral portion 221 is connected to a second mounting surface 212.

[0056] The peripheral portion 221 is the part of the camera 22 used to connect with the first mounting surface 211 or the second mounting surface 212.

[0057] In some embodiments, the peripheral portion 221 is the circuit board of the camera 22, which is electrically connected to the motherboard to realize information exchange between the camera 22 and the motherboard, and is used to connect with the bracket 21 to fix the lens portion 222. This reduces the space occupied by the camera 22 in the housing 10 compared to setting an additional mounting portion, and reduces the volume requirement of the housing 10, thereby helping to reduce the overall size of the GNSS receiver 100.

[0058] In this embodiment, by connecting the peripheral portion 221 to the first mounting surface 211 or by connecting the peripheral portion 221 to the second mounting surface 212, the connection point of the camera 22 is far away from the lens portion 222 when it is connected to the bracket 21. This reduces the risk of the lens portion 222 being damaged by collision during the assembly or disassembly of the camera 22 and improves the production yield of the GNSS receiver 100.

[0059] Please refer to Figures 3-5According to some embodiments of this application, the second mounting surface 212 is provided with a first through hole 213, which penetrates the first mounting surface 211 and the second mounting surface 212. When the peripheral portion 221 is connected to the second mounting surface 212, the lens portion 222 passes through the first through hole 213 and the peripheral portion 221 abuts against the second mounting surface 212.

[0060] The first through hole 213 is a through hole structure that penetrates the first mounting surface 211 and the second mounting surface 212. For example, the axis of the first through hole 213 is perpendicular to the first mounting surface 211 and the second mounting surface 212.

[0061] In some embodiments, the bracket 21 includes a vertical plate 21A, and a first through hole 213 penetrates the vertical plate 21A along the thickness direction of the vertical plate 21A.

[0062] For example, the cross-section of the first through hole 213 can be circular, elliptical, or polygonal.

[0063] In some implementations, the first through hole 213 can be adapted to the outer periphery of the lens portion 222 so that the camera 22 can be positioned relative to the bracket 21 by limiting the lens portion 222 through the first through hole 213.

[0064] In some implementations, there is a gap between the wall of the first through hole 213 and the outer periphery of the lens portion 222 of the camera 22, so that the first through hole 213 can accommodate lens portions 222 of different sizes, thereby increasing the variety of cameras 22 that the bracket 21 can accommodate.

[0065] In this embodiment, by providing a first through hole 213 extending through to the first mounting surface 211 on the second mounting surface 212, and allowing the lens portion 222 to pass through the first through hole 213, on the one hand, the first through hole 213 can serve as a clearance structure, reducing the risk of the bracket 21 interfering with the lens portion 222 when the lens portion 222 is connected to the second mounting surface 212; on the other hand, by having part of the lens portion 222 located within the first through hole 213, the bracket 21 can reduce the risk of damage to the lens portion 222 from external impacts during the installation or removal of the camera module 20.

[0066] Please refer to Figures 3-5 According to some embodiments of this application, the peripheral portion 221 is provided with a second through hole, and the first mounting surface 211 is provided with a first threaded hole 214, which penetrates the first mounting surface 211 and the second mounting surface 212; the GNSS receiver 100 also includes a first connector 23, which passes through the second through hole and is connected to the first threaded hole 214 to fix the camera 22 to the bracket 21.

[0067] The second through hole (not shown in the figure) is a through hole adapted to the first connector 23.

[0068] In some embodiments, the peripheral portion 221 of the camera 22 is provided with a second through hole, and the upright plate 21A of the bracket 21 is provided with a first threaded hole 214 penetrating the first mounting surface 211 and the second mounting surface 212. When the peripheral portion 221 abuts against the first mounting surface 211 or the second mounting surface 212, the second through hole and the first threaded hole 214 are correspondingly provided, that is, the second through hole and the first threaded hole 214 correspond in the thickness direction of the upright plate 21A.

[0069] In some embodiments, the first connector 23 passes through the second through hole, one end of the connector may abut against the peripheral portion 221 on the surface away from the bracket 21, and the other end of the first connector 23 is disposed in the first threaded hole 214. The other end of the first connector 23 may be provided with a thread that matches the first threaded hole 214, and the other end of the first connector 23 is threadedly connected to the first threaded hole 214.

[0070] In some embodiments, the first connector 23 may be a screw or a bolt.

[0071] The first connector 23 can be made of metal. For example, the first connector 23 can be made of copper, iron, aluminum, etc.

[0072] In this embodiment, the first connector 23 passes through the second through hole of the peripheral portion 221 and connects to the first threaded hole 214, which makes the connection between the peripheral portion 221 and the bracket 21 more stable, thereby improving the reliability of the camera 22 installation. At the same time, by passing the first threaded hole 214 through the first mounting surface 211 and the second mounting surface 212, the camera 22 can be installed through the first threaded hole 214 when it is installed on the first mounting surface 211 or the second mounting surface 212 via the first connector 23. On the one hand, it reduces the assembly difficulty and improves the manufacturing convenience of the GNSS receiver 100. On the other hand, compared with the case where threaded holes are respectively set on the first mounting surface 211 and the second mounting surface 212, the processing steps of the bracket 21 are reduced, the processing difficulty of the bracket 21 is reduced, and the manufacturing convenience of the GNSS receiver 100 is improved.

[0073] Please refer to Figures 3-5 According to some embodiments of this application, there are multiple first connectors 23, and the multiple first connectors 23 are arranged at intervals along the circumference of the lens portion 222.

[0074] In some embodiments, the number of first connectors 23 can be 2, 4, 6, 8, etc.

[0075] In some embodiments, the number of first connectors 23 can be four.

[0076] In some embodiments, a plurality of first connectors 23 may be uniformly arranged along the circumference of the lens portion 222, that is, on a cross section perpendicular to the center line of the lens portion 222, the midpoint of the first connector 23 and the midpoint of the lens portion 222 are connected to form a first connecting line, and the included angle of any two adjacent first connecting lines in the circumference of the lens portion 222 is the same.

[0077] In this embodiment, by arranging multiple first connectors 23 at circumferential intervals along the antenna, the connection between the camera 22 and the bracket 21 is made more stable, thereby improving the reliability of the camera 22 installation.

[0078] Please refer to Figure 5 According to some embodiments of this application, the bracket 21 includes a base plate 21B and a vertical plate 21A. The base plate 21B is connected to the inner surface of the housing 10 on one side in its thickness direction. The vertical plate 21A is disposed on the other side of the base plate 21B in its thickness direction. The thickness direction of the vertical plate 21A is perpendicular to the thickness direction of the base plate 21B. The vertical plate 21A has a first mounting surface 211 and a second mounting surface 212 on both sides in its thickness direction.

[0079] The base plate 21B is the part of the bracket 21 used to connect the upright plate 21A and the housing 10.

[0080] The upright plate 21A is the part of the bracket 21 used to connect the camera 22.

[0081] In some embodiments, the base plate 21B is connected to the inner surface of the bottom wall, and one end of the upright plate 21A is connected to the middle of the base plate 21B.

[0082] In this embodiment, by connecting the base plate 21B to the inner surface of the housing 10 on one side of its thickness direction and setting the upright plate 21A on the other side of the base plate 21B in its thickness direction, the base plate 21B can increase the area of ​​connection between the support 21 and the housing 10 compared to the case where the upright plate 21A is directly connected to the inner surface of the housing 10, thereby improving the connection strength between the support 21 and the housing 10.

[0083] Please refer to Figure 2 , Figure 5 and Figure 6 Please refer to Figure 7 , Figure 7 for Figure 1 Enlarged view at point A. According to some embodiments of this application, a limiting post 12 is provided on the inner surface of the housing 10, and a limiting hole 215 corresponding to the limiting post 12 is provided on the bottom plate 21B. The limiting post 12 cooperates with the limiting hole 215 to restrict the movement of the bracket 21 relative to the housing 10.

[0084] In some embodiments, the limiting hole 215 is an oblong hole, and the extending direction of the limiting hole 215 is parallel to the direction in which the limiting post 12 points to the camera window 11 corresponding to the limiting post 12. The width of the limiting hole 215 at the end near the camera window 11 is greater than the width of the oblong hole away from the camera window 11, so that the limiting post 12 can be inserted into the limiting hole 215 from the end near the camera window 11, and the bracket 21 is positioned by the cooperation between the end of the limiting hole 215 away from the camera window 11 and the limiting post 12.

[0085] In some embodiments, the limiting hole 215 is an oblong hole, and one end of the limiting hole 215 near the camera window 11 extends to the side of the base plate 21B facing the camera window 11.

[0086] For clarity, please refer to the following: (The text abruptly ends here, so the translation will only include the first instance.) Figure 7 The area where the limiting hole 215 and the limiting post 12 are located is marked by dashed lines in the figure. It should be noted that the dashed lines and pattern fill are only for the purpose of showing the area of ​​the limiting hole 215 and the limiting post 12, and do not represent any physical meaning.

[0087] In this embodiment, by providing a limiting post 12 on the inner surface of the housing 10 and a limiting hole 215 corresponding to the limiting post 12 on the base plate 21B, the bracket 21 is positioned by the limiting post 12 and the limiting hole 215 during the assembly of the camera module 20. On the one hand, this ensures that the positioning and installation of the bracket 21 and the housing 10 have good accuracy; on the other hand, it facilitates the positioning and installation of the bracket 21 during the assembly process, thereby improving the convenience of manufacturing the GNSS receiver 100.

[0088] Please refer to Figure 2 , Figure 5 and Figure 6 Please refer to Figures 7-9 , Figure 8 for Figure 1 Enlarged view at point B in the middle. Figure 9 for Figure 1 Enlarged view at point C. According to some embodiments of this application, there are multiple camera modules 20, camera windows 11, and limiting posts 12. The multiple limiting posts 12 are configured into multiple groups. The multiple camera modules 20, multiple camera windows 11, and multiple groups of limiting posts 12 correspond one-to-one. The base plate 21B is provided with multiple limiting holes 215, and each limiting hole 215 is provided with at least one limiting post 12.

[0089] Each limiting hole 215 is provided with at least one limiting post 12 corresponding to it. This means that among multiple sets of limiting posts 12, there is one and only one limiting post 12 in one set of limiting posts 12 that corresponds to the limiting hole 215. Alternatively, it means that among multiple sets of limiting posts 12, there are two or more sets of limiting posts 12 that have a limiting post 12 that corresponds to the limiting hole 215.

[0090] For clarity, please refer to the following: (The text abruptly ends here, so the translation will only include the first instance.) Figure 7 and Figure 9 The area where the limiting hole 215 and the limiting post 12 are located is marked by dashed lines in the figure. It should be noted that the dashed lines and pattern fill are only for the purpose of showing the area of ​​the limiting hole 215 and the limiting post 12, and do not represent any physical meaning.

[0091] In some embodiments, the base plate 21B is provided with a first limiting hole 2151, a second limiting hole 2152, a third limiting hole 2153, and a fourth limiting hole 2154. The first limiting hole 2151, the second limiting hole 2152, and the third limiting hole 2153 are oblong holes. The first limiting hole 2151 is located in the middle of the base plate 21B, and one end of the second limiting hole 2152 and the third limiting hole 2153 extends to the side of the base plate 21B facing the camera window 11. The housing 10 is provided with a first camera window 111, a second camera window 112, and a third camera window 113, wherein the second camera window 112 is located above the third camera window 113.

[0092] Reference Figure 7 The first camera window 111 is provided with a first limiting post 121, a second limiting post 122, and a third limiting post 123. When the camera module 20 is installed in the first camera window 111, the first limiting post 121 is inserted into the fourth limiting hole 2154, the second limiting post 122 is inserted into the second limiting hole 2152, and the third limiting post 123 is inserted into the third limiting hole 2153.

[0093] Reference Figure 8 The second camera window 112 is provided with a fourth limiting post 124. When the camera module 20 is installed in the second camera window 112, the fourth limiting post 124 is inserted into the fourth limiting hole 2154, and the side of the camera module 20 away from the fourth limiting post 124 abuts against the upright plate 21A of the bracket 21 of the camera module 20 installed in the third camera window 113, thereby reducing the risk of uneven load distribution of the camera module 20 installed in the second camera window 112. For easier display of the range of the upright plate 21A of the bracket 21 of the camera module 20 installed in the third camera window 113, please refer to... Figure 8In the figure, the area of ​​the support plate 21A of the camera module 20 bracket 21 set in the third camera window 113 is marked by a dashed line. It should be noted that the dashed line and pattern fill are only for the purpose of showing the area of ​​the support plate 21A of the camera module 20 bracket 21 set in the third camera window 113 and do not represent any physical meaning.

[0094] Reference Figure 9 The third camera window 113 is provided with a fifth limiting post 125 and a sixth limiting post 126. When the camera module 20 is installed with the third camera window 113, the fifth limiting post 125 is inserted into the second limiting hole 2152, and the sixth limiting post 126 is inserted into the first limiting hole 2151.

[0095] In this embodiment, by providing multiple limiting holes 215 on the base plate 21B, and ensuring that each limiting hole 215 corresponds to at least one limiting post 12, the limiting holes 215 on the bracket 21 can cooperate with different groups of limiting posts 12 corresponding to different camera windows 11 to limit the installation of the camera 22. This allows one bracket 21 to be adapted to the installation of cameras 22 in different camera windows 11, further reducing the number of bracket types. Consequently, the number of parts that need to be assembled during the assembly of the GNSS receiver 100 is reduced, thereby reducing the assembly difficulty and improving the ease of manufacturing the GNSS receiver 100.

[0096] Please refer to Figure 2 , Figure 5 and Figure 6 Please refer to Figure 7 and Figure 9 According to some embodiments of this application, the base plate 21B is provided with a third through hole 216, and the inner surface of the housing 10 is provided with a second threaded hole 13; the GNSS receiver 100 also includes a second connector, which passes through the third through hole 216 and is connected to the second threaded hole 13 to fix the bracket 21 to the housing 10.

[0097] The second connector can be made of metal; for example, the second connector can be made of copper, iron, aluminum, or other materials.

[0098] In some embodiments, the base plate 21B is provided with a plurality of third through holes 216, and a plurality of second threaded holes 13 may be provided near each camera window 11, with the plurality of second threaded holes 13 corresponding one-to-one with the plurality of third through holes 216. Alternatively, a second threaded hole 13 may be provided near each camera window 11, with the second threaded hole 13 corresponding to one of the third through holes 216.

[0099] To better illustrate the extent of the third through hole 216 and the second threaded hole 13, please refer to... Figure 7 and Figure 9 The area of ​​the third through hole 216 and the second threaded hole 13 is marked by dashed lines in the figure. It should be noted that the dashed lines and pattern fill are only for the purpose of showing the area of ​​the third through hole 216 and the second threaded hole 13 and do not represent any physical meaning.

[0100] In this embodiment, the second connector passes through the third through hole 216 and is connected to the second threaded hole 13, which makes the connection between the base plate 21B and the housing 10 more stable, thereby improving the reliability of the bracket 21 installation.
