Description

Technical Field

[0001] This invention relates to the field of vehicle positioning accessories technology, and more specifically to a combined structure for the protection of vehicle-mounted positioning equipment. Background Technology

[0002] Installing vehicle-mounted GPS, BeiDou, Zigbee, UWB, or Bluetooth positioning devices within the vehicle body structure is crucial for monitoring vehicle location and ensuring vehicle safety. Their protective performance directly determines the effectiveness of vehicle safety.

[0003] Existing installation and protection solutions for vehicle-mounted GPS positioning devices, vehicle-mounted BeiDou positioning devices, vehicle-mounted Zigbee positioning devices, vehicle-mounted UWB positioning devices, or vehicle-mounted Bluetooth positioning devices have significant technical flaws: 1. There are three main types of installation solutions: (1) The magnetic fixing method is attached to the inside of the car body by magnetic force and can be manually removed without tools; (2) It can be easily removed after being installed inside the water tank; (3) Wired vehicle GPS positioning devices, vehicle Beidou positioning devices, vehicle Zigbee positioning devices, vehicle UWB positioning devices, or vehicle Bluetooth positioning devices rely on power supply lines and can be removed by tracing the lines. All three methods are unable to prevent malicious disassembly, which makes the positioning function easily interrupted and seriously affects vehicle safety. 2. Existing vehicle-mounted GPS positioning devices, vehicle-mounted Beidou positioning devices, vehicle-mounted Zigbee positioning devices, vehicle-mounted UWB positioning devices, or vehicle-mounted Bluetooth positioning devices only have basic plastic shells and no special anti-vandalism design. When faced with external forces such as sawing, chiseling, and smashing, the shell is easily damaged and the internal positioning module is easily malfunctioned, making it impossible to maintain positioning function under violent destruction scenarios. 3. Existing vehicle-mounted GPS positioning devices, vehicle-mounted Beidou positioning devices, vehicle-mounted Zigbee positioning devices, vehicle-mounted UWB positioning devices, and vehicle-mounted Bluetooth positioning devices lack targeted sealing protection. Bumps, rainwater infiltration, and dust accumulation during vehicle operation can easily lead to water ingress, component corrosion, or vibration damage, shortening the service life of the devices and affecting the continuity of positioning data. 4. Reliability-fixed solutions require specialized tools and technicians, resulting in low installation efficiency and high costs; 5. Although the simplified installation solution is easy to operate, it has poor anti-disassembly and anti-damage performance, and cannot balance the needs of "easy installation" and "reliable protection", making it difficult to meet the needs of large-scale application scenarios. Summary of the Invention

[0004] The purpose of this invention is to provide a technical solution that solves the problems in the prior art mentioned in the background section by encapsulating and fixing the positioning device inside the vehicle frame cavity and providing a multi-layer protective structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A combined structure for protecting vehicle-mounted positioning devices includes: A moldable container and a positioning device are provided. The positioning device is located inside the moldable container. The moldable container is placed inside the cavity of the vehicle frame. An injection tube is inserted into the inside of the moldable container. Foaming adhesive can be injected into the inside of the moldable container through the injection tube. After the foaming adhesive is injected into the inside, the moldable container will expand, support and bond to the inside of the vehicle frame cavity. The positioning device is provided with an inner protective layer and an outer protective layer. The inner protective layer, the outer protective layer and the frame cavity structure constitute a three-layer protective structure for the positioning device. The bottom of the glue inlet tube is detachably connected to a glue injection tube, which is used to extend from the outside of the frame to the inside of the frame cavity to inject glue into the plastic container.

When the glue injection tube and the glue in the docking state, they can support the plastic container and the positioning device to extend into the cavity structure of the vehicle frame. After the glue is injected through the glue injection tube and the glue in the glue injection tube, the glue injection tube and the glue in the glue injection tube are separated.

[0011] Preferably, the positioning device is installed on the glue inlet tube by a fixing buckle. After the glue is injected, the glue inlet tube is kept in the plastic container. The straight connector is provided with a one-way valve to prevent the foamed adhesive from flowing back.

[0012] Preferably, the frame cavity structure includes the A-pillar cavity structure, B-pillar cavity structure, and C-pillar cavity structure of the vehicle frame.

[0015] Technical effects and advantages of the present invention: The combined structure for protecting vehicle-mounted positioning devices proposed in this invention has the following advantages compared with the prior art: This invention utilizes a positioning device built into a malleable container and injects foamed adhesive through a glue inlet tube, causing the container to expand and adhere tightly to the inner wall of the frame cavity, forming a fixed support. At the same time, the internal and external protective layers of the positioning device work together with the frame cavity structure to form a three-layer physical barrier, and the glue inlet tube can be detachably connected to the glue inlet tube to achieve precise glue injection from the outside of the frame.

[0016] The expansion bonding mechanism ensures that the equipment is stably positioned in the frame cavity, preventing displacement caused by external damage; the three-layer protective structure significantly improves impact resistance and environmental isolation capabilities, extending the equipment's lifespan; the detachable adhesive injection design simplifies the installation process, balancing ease of operation with reliable sealing.

[0019] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0020] The invention provides, for example Figures 1 to 5 As shown, a combined structure for protecting vehicle-mounted positioning devices includes: A malleable container 11 and a positioning device 12 are provided inside the malleable container 11. The malleable container 11 is placed inside the cavity of the vehicle frame. An inlet tube 13 is inserted into the malleable container 11. Foaming adhesive can be injected into the malleable container 11 through the inlet tube 13. After the foaming adhesive is injected into the malleable container 11, the malleable container 11 will expand, support and adhere to the inside of the vehicle frame cavity. The positioning device 12 is provided with an inner protective layer and an outer protective layer. The inner protective layer, the outer protective layer and the frame cavity structure constitute a three-layer protective structure for the positioning device 12. The bottom of the glue inlet tube 13 is detachably connected to a glue injection tube 14. The glue injection tube 14 is used to extend from the outside of the frame to the inside of the frame cavity to inject glue into the plastic container 11.

[0021] Working principle: The positioning device 12 is built into the malleable container 11, and foaming adhesive is injected through the glue injection tube 13. After the container expands, it is tightly bonded to the inner wall of the frame cavity to form a fixed support. At the same time, the internal protective layer of the positioning device 12 and the external protective layer work together with the frame cavity structure to form a three-layer physical barrier. The glue injection tube 14 can be detachably connected to the glue injection tube 13 to achieve precise glue injection from the outside of the frame.

[0022] The expansion bonding mechanism ensures that the equipment is stably positioned in the frame cavity, preventing displacement caused by external damage; the three-layer protective structure significantly improves impact resistance and environmental isolation capabilities, extending the equipment's lifespan; the detachable adhesive injection design simplifies the installation process, balancing ease of operation with reliable sealing.

[0023] To enhance the positioning device's impact resistance and anti-tampering capabilities, a double-layer protective structure is used to provide precise protection for the internal electronic components. The outer protective layer is a composite shell made of 2.5mm thick high-carbon steel and 3mm thick ceramic matrix composite material, while the inner protective layer is an epoxy resin potting layer. The positioning device 12 is positioned inside the outer protective layer by epoxy resin potting.

[0024] Regarding the structural composition of the double-layer protective structure: the outer protective layer is a composite shell of 2.5mm thick high-carbon steel and 3mm thick ceramic matrix composite material, with the high-carbon steel and ceramic being bonded and fixed by casting adhesive; its anti-disassembly and anti-damage features: the aluminum alloy layer can withstand 50J of impact energy and disperse local impact force; the ceramic layer has a hardness of ≥HRC90, and the cutting edge of the electric drill becomes dull after a few minutes of drilling, which greatly increases the difficulty of tool disassembly; Through the coating effect of epoxy resin and the buffering and positioning effect of the fixing adhesive, external vibration energy is absorbed, achieving shock protection for electronic components such as circuit boards, chips, communication modules, control antennas, and batteries, preventing problems such as component detachment and solder joint failure caused by vibration.

[0025] like Figure 4 and Figure 5 As shown, this ensures the sealing and connection stability of the glue injection pipeline during the connection process, avoids adhesive leakage during glue injection, and allows for convenient disassembly of the pipeline after glue injection; a straight connector 15 is provided at the position where the glue inlet tube 13 is inserted into the malleable container 11, and the glue injection tube 14 is detachably connected to the glue inlet tube 13 through the straight connector 15; a sealing buckle 16 is provided on the malleable container 11 to lock and fix the straight connector 15.

[0026] like Figure 5 As shown, in order to achieve active anti-tampering monitoring of the protective structure, to sense in real time whether the protective system has been broken or damaged, and to trigger warning signals in a timely manner to improve the proactiveness of protection; the bottom surface of the malleable container 11 is provided with a protective metal mesh 19, which forms a passage with the positioning device 12 through two sets of connecting wires 110. When the protective metal mesh 19 on the bottom surface of the malleable container 11 is broken or damaged, the passage will be damaged and a warning signal will be issued through the positioning device 12.

[0027] To ensure that the mixed foam adhesive is fully and evenly mixed before dispensing, and to guarantee that it reaches the preset strength and bonding performance after curing, while also achieving precise delivery of the adhesive, the dispensing tube 14 is connected to the dispensing nozzle 23 of the dispensing device 21 via the mixing tube 24. The dispensing device 21 is used to install the glue tank 22 for storing the foam adhesive. The foam adhesive is set as a mixed foam adhesive, and the mixing tube 24 has a spiral structure inside for mixing the raw materials of the foam adhesive.

[0028] It should be noted that, in order to achieve accurate depth positioning of the positioning device in the vehicle frame cavity, temporary support is provided by the glue injection pipe to avoid installation displacement without affecting the integrity of the protective structure after glue injection; the glue injection pipe 14 is provided with a depth mark 25, which is used to mark the depth of the positioning device 12 inserted into the vehicle frame cavity structure. When the glue inlet pipe 13 and the glue injection pipe 14 are docked, they can support the malleable container 11 and the positioning device 12 to be inserted into the vehicle frame cavity structure. After the glue injection is completed through the glue inlet pipe 13 and the glue injection pipe 14, the glue inlet pipe 13 and the glue injection pipe 14 are separated.

[0029] To fix the positioning device in the plastic container, prevent the device from shifting during glue injection and foaming expansion, avoid adhesive backflow, and enhance the sealing effect after glue injection, the positioning device 12 is installed on the glue inlet pipe 13 by a fixing buckle 17. The glue inlet pipe 13 is retained in the plastic container 11 after glue injection. The straight connector 15 is equipped with a one-way valve 18 to prevent the backflow of foamed adhesive.

[0030] like Figure 1 and Figure 2 As shown in the figure, the B-pillar structure of a conventional vehicle is illustrated. To clarify the applicable installation scenarios for the combined structure and limit the types of cavities that can be adapted to the vehicle frame, the practicality and specificity of the solution are improved. The frame cavity structure includes the A-pillar cavity structure, B-pillar cavity structure, and C-pillar cavity structure of the vehicle frame. In actual use cases, the frame cavity structure of various vehicle types such as passenger cars, trucks, motorcycles, electric vehicles, and bicycles can be selected as the installation location for the positioning device 12.

[0031] In order to clarify the core components and communication adaptation capabilities of the positioning device and meet the functional requirements of different vehicle positioning scenarios, the positioning device 12 includes an internal circuit board, a control chip, a communication module, an antenna, and a battery. The communication module is configured as one or more of the following: vehicle GPS communication module, vehicle Beidou communication module, vehicle Zigbee communication module, vehicle UWB communication module, and vehicle Bluetooth communication module.

[0032] To standardize the installation process of the combined structure, ensure the coordinated effectiveness of all protective components, piping, and monitoring functions, and guarantee the protective effect and functional stability, the following operating methods are included, with specific steps: Step S1: Pre-assembly of protective components; First, the internal circuit board, control chip, communication module, antenna, battery and other electronic components of the positioning device 12 are encapsulated with epoxy resin to form an internal protective layer with a thickness of 3-5mm. Then, the encapsulated positioning device 12 is installed into a composite shell of 2.5mm thick high carbon steel and 3mm thick ceramic matrix composite material to ensure that the positioning device 12 is firmly positioned inside the outer protective layer through epoxy resin encapsulation. Subsequently, the positioning device 12 with the protective layer assembled is placed inside the plastic container 11. The positioning device 12 is fixedly connected to the glue inlet tube 13 inside the plastic container 11 by the fixing buckle 17. At the same time, a protective metal mesh 19 is laid on the bottom surface of the plastic container 11, and the protective metal mesh 19 is electrically connected to the control chip of the positioning device 12 through two sets of connecting wires 110 to form an anti-tamper monitoring path. Step S2: Pre-treatment of the frame cavity; Select the A-pillar cavity structure, B-pillar cavity structure or C-pillar cavity structure of the vehicle frame as the installation cavity, clean the impurities, oil stains and floating rust on the inner wall of the cavity, and ensure that the inside of the cavity is flat and free of protruding obstacles to avoid affecting the fitting effect of the plastic container 11 after expansion. Step S3: Connecting and positioning the glue injection pipeline; The glue inlet tube 13 is detachably connected to the glue injection tube 14 via the straight connector 15. The straight connector 15 is locked and fixed by the sealing buckle 16 to prevent leakage during the glue injection process. According to the depth mark 25 on the glue injection tube 14, the plastic container 11 together with the positioning device 12 is inserted into the preset installation depth along the frame cavity. At this time, the glue injection tube 14 extends from the outside of the frame into the cavity, which plays a temporary support and positioning role. Step S4: Injecting the foamed adhesive; The raw material of the mixed foam adhesive is loaded into the glue tank 22 of the glue dispenser 21. The glue dispenser 21 is started, and the adhesive raw material enters the mixing tube 24 through the glue outlet 23. After being fully mixed by the spiral structure inside the mixing tube 24, it is injected into the plastic container 11 through the glue injection tube 14, the straight connector 15, and the glue inlet tube 13. During the injection process, the filling status of the adhesive is observed to ensure that the filling rate is ≥95%. At this time, under the expansion force of the foam adhesive, the plastic container 11 is tightly attached to the inner wall of the frame cavity and is bonded and fixed. The one-way valve 18 in the straight connector 15 prevents the adhesive from flowing back. Step S5: Curing and separation from pipelines; After stopping the glue injection, keep the glue injection pipeline connected and follow the curing parameters of the foamed adhesive, such as curing at room temperature for 30-60 minutes and letting it stand until the adhesive is completely cured. After curing, the shear strength is ≥22MPa and the Shore hardness is ≥D85. After curing, loosen the sealing buckle 16, disconnect the glue injection tube 14 at the straight connector 15, and leave the glue inlet tube 13 in the plastic container 11 to form a sealed structure. At this time, the adhesive sealing layer reaches the IP68 waterproof and dustproof rating. Step S6: Anti-tamper monitoring activation and function verification; The anti-tamper monitoring function is activated by the communication module of the positioning device 12 to detect whether the path formed by the protective metal mesh 19 and the positioning device 12 is connected. If the path is normal, the positioning device 12 sends back a signal indicating that the installation is complete through communication modules such as GPS / BeiDou. If the protective metal mesh 19 is subsequently broken or damaged, and the path is disconnected, the positioning device 12 immediately issues a warning signal, thus activating the integrated protection system.

[0033] In summary, the present invention also has the following combined effects: Plastic container and expanding foam adhesive: By injecting expanding foam adhesive into the plastic container 11 placed in the vehicle frame cavity, the container expands and firmly supports and adheres to the inside of the frame, providing a stable installation environment for the positioning device 12. Double-layer protective structure: The positioning device 12 is encapsulated with epoxy resin to form an inner protective layer, and further encapsulated with an outer protective layer composed of 2.5mm thick high-carbon steel and 3mm thick ceramic matrix composite material. This double-layer protective structure can effectively absorb vibration energy and improve the device's impact resistance and anti-tampering capabilities. Sealing and Convenience of the Injection Pipeline: The inlet pipe 13 and the injection pipe 14 are detachably connected via a straight connector 15, and the sealing and connection stability during the injection process are ensured by a sealing lock 16. Furthermore, after injection, the pipeline is easy to disassemble without affecting the integrity of the protective structure. The passive anti-tamper structure is combined with active anti-tamper monitoring: the protective metal mesh 19 set on the bottom of the plastic container and the positioning device 12 form a path to monitor whether the protection system is damaged in real time. Once damage is detected, a warning signal is triggered immediately, which improves the initiative of protection.

[0034] Enhanced protective performance: The double-layer protective structure significantly improves the positioning device's impact resistance and tamper resistance, ensuring the safety of electronic components. A simple and reliable installation process: The entire installation process, from pre-assembly of protective components to activation of tamper monitoring, is standardized and orderly, ensuring effective coordination of all components and simplifying operation. An efficient tamper monitoring mechanism: Through the electrical connection between the protective metal mesh 19 and the positioning device, real-time monitoring of the integrity of the protective system is achieved, greatly enhancing safety. Excellent sealing performance: The use of foam adhesive and a one-way valve 18 not only ensures smooth glue application but also achieves IP68 waterproof and dustproof standards, significantly improving the overall protection level. This invention, through a series of innovative designs, effectively improves the protection level of vehicle-mounted positioning devices, adapts to the needs of various vehicle models, and possesses strong practical value and market application prospects.

The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention, all of which are within the protection scope of the present invention.
