Description

Technical Field

[0001] This utility model relates to the field of BeiDou positioning module technology, specifically a miniaturized BeiDou positioning module that is easy to install. Background Technology

[0002] A miniaturized BeiDou positioning module is an electronic component capable of receiving BeiDou satellite signals to determine location information, and it has a small size. Functionally, it is similar to a regular BeiDou positioning module, receiving signals transmitted by multiple BeiDou satellites and using information such as the time difference of these signals arriving at the module to perform complex calculations to determine its own three-dimensional position (longitude, latitude, and altitude), while also obtaining accurate time information. Structurally, miniaturization is its main feature. It adopts highly integrated chip technology and compact circuit design, making the entire module smaller. This allows it to be easily embedded in various small electronic devices, such as smartwatches, small trackers, and drones, providing these devices with accurate positioning functions without occupying too much space. When the miniaturized BeiDou positioning module is used in scenarios with complex electromagnetic environments, such as in environments with many other electronic devices and cluttered electromagnetic signals, or where the device it is in has high capacitance requirements, it will be equipped with a shielding cover and shielding frame to ensure positioning accuracy and stability.

[0003] Based on the above, the inventors have discovered the following problems: Currently, the connection between the shielding cover and the shielding frame of the Beidou positioning module is mostly achieved by welding or bolting. Welding makes it difficult to disassemble the shielding cover later. Bolting requires pre-drilling screw holes at corresponding positions on the shielding cover and the shielding frame. The bolts are then passed through the holes in the shielding cover and screwed into the screw holes in the shielding frame. Tools are needed during installation and disassembly, resulting in slow installation and disassembly speeds and reduced efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a miniaturized BeiDou positioning module that is easy to install, in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this invention is to provide a miniaturized BeiDou positioning module that is easy to install, so as to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A miniaturized BeiDou positioning module that is easy to install includes a main body, the main body including a BeiDou positioning plate, an antenna feed point through hole opened inside the BeiDou positioning plate, an antenna welded to the bottom end of the BeiDou positioning plate at the antenna feed point through hole, and an RF front end installed at the top end of the BeiDou positioning plate. A shielding frame is welded to the top surface of the BeiDou positioning plate, and an RF module, a baseband processing module and a power supply module are installed inside the shielding frame at the top end of the BeiDou positioning plate. A shielding cover is fitted outside the shielding frame, and first circular holes are opened on both sides of the shielding frame. Second circular holes are opened on both sides of the shielding cover at the first circular holes. An installation component is provided between the opposing first and second circular holes.

[0008] Furthermore, the mounting assembly includes a first empty cylinder and a second empty cylinder, which are respectively installed inside the first circular hole and the second circular hole. The inner wall of the first empty cylinder is provided with four first sliding grooves, and a connecting plate is slidably connected between the four first sliding grooves. A plug rod is installed at one end of the connecting plate, and the plug rod extends through the second empty cylinder into the interior at the end away from the connecting plate, and is in clearance fit with the through hole of the second empty cylinder.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, since the end of the plug rod away from the connecting plate is located inside the second empty cylinder, the connection between the shielding frame and the shielding cover is realized. Through the cooperation of the first slide groove and the connecting plate, the movement direction of the connecting plate is restricted, so that it can only move along the direction of the first slide groove.

[0010] Furthermore, the four first grooves are distributed in an equally spaced ring, the longitudinal section of the connecting plate is cross-shaped, and the connecting plate is connected to a mounting plate on the side away from the insertion rod. A spring is installed on the side of the mounting plate away from the connecting plate, and the end of the spring away from the mounting plate is connected to the inner wall of the first empty cylinder.

[0011] The beneficial effect of adopting the above-mentioned further solution is that, through the coordinated use of the connecting plate, the mounting plate and the spring, when the insertion rod is squeezed and retracts into the first empty cylinder, the connecting plate will continuously move towards the spring under the action of the first sliding groove, causing the mounting plate to squeeze the spring. By setting the spring, when the squeezing force on the spring disappears, it is easy to realize the reset of the insertion rod under the action of the spring force.

[0012] Furthermore, a second sliding groove is provided on both sides of the inner wall of the second hollow cylinder. A first circular plate and a second circular plate are slidably connected between a pair of second sliding grooves. A pressing rod is connected between the first circular plate and the second circular plate. One end of the pressing rod abuts against the end of the insertion rod away from the connecting plate, and the pressing rod extends through the second hollow cylinder to the outside at the end away from the insertion rod, and is in clearance fit with the through hole of the second hollow cylinder.

[0013] The beneficial effect of adopting the above-mentioned further solution is that, through the cooperative use of the pressing rod and the insert rod, the ends of the pressing rod and the insert rod abut against each other. When the pressing rod is squeezed into the interior of the second empty cylinder, the first circular plate and the second circular plate move continuously toward the insert rod under the action of the second sliding groove. When the side of the second circular plate away from the first circular plate is in contact with the side of the second empty cylinder near the insert rod, the end of the insert rod away from the connecting plate is made flush with the side of the first empty cylinder away from the first circular hole under the action of the pressing rod, so as to facilitate the separation of the shielding cover and the shielding frame.

[0014] Furthermore, the outer wall of the shielding frame and the inner wall of the shielding cover are fitted with a clearance.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, due to the gap fit between the outer wall of the shielding frame and the inner wall of the shielding cover, the shielding cover is fitted over the outside of the shielding frame, making the connection between the shielding cover and the shielding frame tighter and having a certain electromagnetic shielding effect.

[0016] Furthermore, the RF front end includes an amplifier circuit and a filter circuit, the RF module includes an RF chip, a matching circuit and a voltage-controlled temperature-compensated crystal oscillator, and the baseband processing module includes a baseband core circuit, a reset circuit, a FLASH circuit and an RTC circuit.

[0017] The beneficial effect of adopting the above-mentioned further solution is that, since the bottom of the Beidou positioning board is located at the antenna feed point through-hole, the satellite signal is introduced into the Beidou positioning board through the antenna feed point through-hole. The signal is amplified by the amplification circuit, filtered by the filtering circuit, and then sent to the RF module. The RF module includes an RF chip, a matching circuit, and a voltage-controlled temperature-compensated crystal oscillator to complete the RF processing of the RF signal and output the corresponding intermediate frequency signal from the receiving channel to the baseband processing module. The baseband processing module includes a baseband core circuit, a reset circuit, a FLASH circuit, and an RTC circuit. The baseband core circuit performs tasks such as signal acquisition, tracking, navigation message demodulation and decoding, raw observation extraction, and PVT calculation on the received frequency point, and outputs positioning, velocity measurement, and other data required by the protocol. The reset circuit provides a stable reset signal when the Beidou positioning board is powered on, ensuring that the baseband processing module can be powered on and operated correctly. The FLASH circuit is used to store the program and some data of the baseband chip, and the RTC circuit realizes the hot start function of the Beidou positioning board.

[0018] Furthermore, the radio frequency front-end, radio frequency module, baseband processing module, and power supply module are electrically connected by wires.

[0019] The beneficial effects of adopting the above-mentioned further scheme are that the radio frequency front-end receives satellite signals and performs amplification, filtering and other processing; the radio frequency module performs frequency conversion processing on the radio frequency signals to obtain the corresponding intermediate frequency signals and outputs them to the baseband processing module; the baseband processing module completes signal acquisition, tracking, and calculation and outputs positioning, speed measurement and other protocol information; and the power supply module provides stable power to the various module circuits of the Beidou positioning board.

[0020] Compared with existing technologies, the beneficial effects of this utility model are as follows: This easily installable miniaturized BeiDou positioning module has its antenna welded to the BeiDou positioning plate through an antenna feed point through-hole, featuring miniaturization and low power consumption. Simultaneously, because the antenna is welded at the bottom of the BeiDou positioning plate at the antenna feed point through-hole, satellite signals are introduced into the BeiDou positioning plate through the antenna feed point through-hole. The RF front-end receives the satellite signals and performs amplification, filtering, and other processing. The RF module performs frequency conversion processing on the RF signals to obtain the corresponding intermediate frequency signal and outputs it to the baseband processing module. The baseband processing module completes signal acquisition, tracking, and calculation, and outputs positioning, speed measurement, and other protocol information. The power module provides stable power to the various module circuits of the BeiDou positioning plate. When it is necessary to install the shielding cover outside the shielding frame, align the bottom end of the shielding cover with the top end of the shielding frame and press it down continuously. The operator presses the insert rod into the first empty cylinder, making the end of the insert rod away from the connecting plate flush with the side of the first empty cylinder away from the first circular hole. This facilitates further pressing down on the shielding cover. During the pressing process, the insert rod is pressed against the inner wall of the shielding cover until the end of the insert rod away from the connecting plate aligns with the through hole of the second empty cylinder. Then, under the elastic force of the spring, one end of the insert rod is inserted into the second empty cylinder through the through hole, completing the connection between the shielding cover and the shielding frame. When it is necessary to disassemble the shielding cover, pressing the pressure rod into the second empty cylinder causes the first and second circular plates to move continuously towards the insert rod under the action of the second sliding groove. When the side of the second circular plate away from the first circular plate is in contact with the side of the second empty cylinder near the insert rod, the pressure rod makes the end of the insert rod away from the connecting plate flush with the side of the first empty cylinder away from the first circular hole, facilitating the separation of the shielding cover and the shielding frame.

A shielding cover 1009 is fitted outside the shielding frame 1008. A first circular hole 200 is opened on both sides of the shielding frame 1008.

Two circular holes 300 are provided, and a mounting component 400 is provided between the first circular hole 200 and the second circular hole 300. The antenna 1003 is welded to the Beidou positioning board 1001 through the antenna feed point through hole 1002. It has the characteristics of miniaturization and low power consumption, so that the satellite signal is introduced into the Beidou positioning board 1001 through the antenna feed point through hole 1002. The radio frequency front end 1004 processes the received satellite signal and performs amplification, filtering and other processing. The radio frequency module 1005 performs frequency conversion processing on the radio frequency signal to obtain the corresponding intermediate frequency signal and outputs it to the baseband processing module 1006.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-6This utility model provides a technical solution: the mounting assembly 400 includes a first empty cylinder 4001 and a second empty cylinder 4002, which are respectively installed inside a first circular hole 200 and a second circular hole 300. The inner wall of the first empty cylinder 4001 has four first sliding grooves 4003, and a connecting plate 4004 is slidably connected between the four first sliding grooves 4003. A rod 4006 is installed at one end of the connecting plate 4004, and the rod 4006 extends through the second empty cylinder 4002 into the interior at the end furthest from the connecting plate 4004, and intersects with the through hole of the second empty cylinder 4002. The four first sliding grooves 4003 are evenly spaced in a ring. The longitudinal section of the connecting plate 4004 is cross-shaped, and a mounting plate 4005 is connected to the side of the connecting plate 4004 away from the insert rod 4006. A spring 4007 is installed on the side of the mounting plate 4005 away from the connecting plate 4004. The end of the spring 4007 away from the mounting plate 4005 is connected to the inner wall of the first empty cylinder 4001. Second sliding grooves 4008 are opened on both sides of the inner wall of the second empty cylinder 4002. A first circular plate 4009 and a second circular plate 4010 are slidably connected between a pair of second sliding grooves 4008. A pressing rod 4011 is connected between the first circular plate 4009 and the second circular plate 4010. One end of the pressing rod 4011 abuts against the end of the insert rod 4006 away from the connecting plate 4004. The end of the pressing rod 4011 away from the insert rod 4006 extends through the second hollow cylinder 4002 to the outside and is clearance-fitted with the through hole of the second hollow cylinder 4002. Since the end of the pressing rod 4011 abuts against the opposite end of the insert rod 4006, when the pressing rod 4011 is pressed into the second hollow cylinder 4002, the first circular plate 4009 and the second circular plate 4010 move continuously toward the insert rod 4006 under the action of the second sliding groove 4008. When the rod 4006 is compressed and retracts into the first empty cylinder 4001, the connecting plate 4004 will continuously move towards the spring 4007 under the action of the first sliding groove 4003, causing the mounting plate 4005 to compress the spring 4007. When the second circular plate 4010 is in contact with the side of the second empty cylinder 4002 near the insertion rod 4006 on the side away from the first circular plate 4009, the end of the insertion rod 4006 away from the connecting plate 4004 is flush with the side of the first empty cylinder 4001 away from the first circular hole 200 under the action of the pressing rod 4011, so as to facilitate the separation of the shielding cover 1009 and the shielding frame 1008.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-6 This utility model provides a technical solution: the outer wall of the shielding frame 1008 and the inner wall of the shielding cover 1009 are fitted with a gap; the radio frequency front-end 1004 includes an amplifier circuit and a filter circuit; the radio frequency module 1005 includes an radio frequency chip, a matching circuit, and a voltage-controlled temperature-compensated crystal oscillator; the baseband processing module 1006 includes a baseband core circuit, a reset circuit, a FLASH circuit, and an RTC circuit; the radio frequency front-end 1004, the radio frequency module 1005, the baseband processing module 1006, and the power supply module are electrically connected by wires. Because the outer wall of the shielding frame 1008 and the inner wall of the shielding cover 1009 are fitted with a gap, the shielding cover 1009 is fitted over the shielding frame 1008, making the connection between the shielding cover 1009 and the shielding frame 1008 tighter and providing a certain electromagnetic shielding effect. When a satellite signal is introduced into the Beidou positioning board 1001 through the antenna feed point through-hole 1002, the amplifier circuit amplifies the signal. The signal is then filtered by a filtering circuit and sent to the radio frequency module 1005. The radio frequency module 1005 includes an radio frequency chip, a matching circuit, and a voltage-controlled temperature-compensated crystal oscillator to complete the radio frequency processing of the radio frequency signal and output the corresponding intermediate frequency signal from the receiving channel to the baseband processing module 1006. The baseband processing module 1006 includes a baseband core circuit, a reset circuit, a FLASH circuit, and an RTC circuit. The baseband core circuit performs tasks such as capturing, tracking, demodulating and decoding navigation messages, extracting raw observations, and performing PVT calculations on the received frequency signals, and outputs positioning, speed measurement, and other data required by the protocol. The reset circuit provides a stable reset signal when the Beidou positioning board 1001 is powered on, ensuring that the baseband processing module 1006 can be powered on and operated correctly. The FLASH circuit is used to store the program and some data of the baseband chip, and the RTC circuit realizes the hot start function of the Beidou positioning board 1001.

[0034] Specifically, the working principle of this easy-to-install miniaturized Beidou positioning module is as follows: When the shielding cover 1009 needs to be fitted onto the outside of the shielding frame 1008, align the bottom end of the shielding cover 1009 with the top end of the shielding frame 1008 and press down continuously. Then, the operator pushes the insert rod 4006 into the interior of the first empty cylinder 4001, making the end of the insert rod 4006 away from the connecting plate 4004 flush with the side of the first empty cylinder 4001 away from the first circular hole 200. Then, the shielding cover 1009 can be pressed down further. During the pressing process, the insert rod 4006 is pressed against the inner wall of the shielding cover 1009 until the end of the insert rod 4006 away from the connecting plate 4004 is aligned with the through hole of the second empty cylinder 4002. Then, under the elastic force of the spring 4007, one end of the insert rod 4006 is inserted into the interior of the second empty cylinder 4002 through the through hole, completing the connection between the shielding cover 1009 and the shielding frame 1008. The miniaturized BeiDou positioning module is then installed in the customer's complete equipment. Since the BeiDou positioning board 1001 and the antenna 1003 are integrated, they are interconnected with the customer's complete equipment through the interface on the antenna 1003. The antenna 1003 is soldered to the BeiDou positioning board 1001 through the antenna feed point through hole 1002. It has the characteristics of miniaturization and low power consumption, so that the satellite signal is introduced into the BeiDou positioning board 1001 through the antenna feed point through hole 1002. The radio frequency front end 1004 processes the received satellite signal and performs amplification, filtering and other processing. The radio frequency module 1005 performs frequency conversion processing on the radio frequency signal to obtain the corresponding intermediate frequency signal and outputs it to the baseband processing module 1006. The baseband processing module 1006 completes the signal acquisition, tracking, and calculation, and outputs positioning, speed measurement and other protocol information. The power supply module 1007 provides a stable power supply for the circuits of each module of the BeiDou positioning board 1001.
