Description

Technical Field

[0001] This utility model relates to the field of wireless communication technology, and more specifically, to an RTK receiver, an electronic device, and a mobile vehicle. Background Technology

[0002] The RTK (Real-Time Kinematic) antenna is a key component integrated into an RTK system. Its primary responsibility is to receive radio frequency (RF) signals from satellites (such as GPS, GLONASS, Galileo, and BDS) and convert them into digital information that can be interpreted by subsequent processing units. Its operation is based on the carrier phase differential principle: it first receives RF signals from multiple satellites, then preprocesses them using an internal low-noise amplifier (LNA) and a high-precision clock. Next, the antenna transmits the signal to the RTK receiver, which calculates the rover's precise position in real time by comparing the phase difference between the satellite signals received by the base station and the rover.

[0003] Existing smart high-precision RTK antennas on the market have a bottom waterproof structure and interface that are not only far apart, but also lack a sealed protective structure. This results in them occupying most of the bottom space, affecting the setting of other mounting holes, making the overall size larger and the interface position inconvenient to plug and unplug.

[0004] For example, Chinese patent application number 201720018486.0, entitled "Miniature Intelligent Inertial Navigation GNSS-RTK Receiver," discloses a GNSS-RTK receiver with functional interfaces on its lower end face. These interfaces include a five-pin LEMO interface, a seven-pin LEMO interface, a UHF antenna interface, a UMTS network antenna interface, and so on. However, the interface slots are directly located on the end face, which not only hinders the protection and sealing of each interface but also lacks waterproof sealing for the entire end face, significantly impacting daily use and maintenance for users. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an RTK receiver, electronic device and mobile vehicle to solve the above problems.

[0006] To achieve the purpose of this utility model, the following solution is adopted:

[0007] This application provides an RTK receiver device, including a housing, a control circuit board, an RTK antenna module, and an interface module disposed within the housing; the RTK antenna module and the interface module are electrically connected to the control circuit board respectively; a socket groove communicating with the interface module is correspondingly recessed on the end face of the housing, and a sealing groove is formed around the outer periphery of the end face; a sealing gasket is correspondingly fitted in the sealing groove; the sealing groove is at least partially communicating with the socket groove.

[0008] As a further improvement, the socket groove is configured as a rectangular notch groove, with the notch facing the same height as the sealing groove and smoothly connected.

[0009] As a further improvement, the socket slot has an arc surface on one side where the notch is located and a sloping surface on the opposite side, so that the socket slot is constructed as a whole to present an expanded shape suitable for plugging into the interface module.

[0010] As a further improvement, the housing includes a base and a cover; the base has a top opening, and the cover is detachably screwed onto the top opening.

[0011] As a further improvement, the control circuit board is mounted in the housing via a base; the RTK antenna module and interface module are correspondingly attached to the control circuit board.

[0012] As a further improvement, the end face is formed on the cover, and a label for recording product information is provided in the central area of ​​the cover.

[0013] As a further improvement, the insertion slot and the label are arranged on the same end face to avoid each other; and multiple fixing nuts are provided on the end face accordingly. The fixing nuts are used to tighten the end face so that the relative position of the sealing groove changes to compress the sealing gasket.

[0014] As a further improvement, the base and the cap cooperate to form a bottle cap shape, and a sealing ring is fitted at the screw connection between the base and the cap.

[0015] In addition, this application also provides an electronic device, including the above-described RTK receiving device.

[0016] In addition, this application also provides a mobile vehicle including the aforementioned RTK receiving device.

[0017] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0018] 1. The RTK receiver of this application has an annular sealing groove on the end face of the outer shell and a sealing gasket is placed inside the groove, so that a complete sealing barrier is formed around the socket groove, and the sealing groove is partially connected to the socket groove, ensuring that the sealing gasket can fit and fill the gap of the plug-in part, effectively preventing moisture and dust from entering the interface module.

[0019] 2. The insertion slot and sealing slot are both located on the end face of the housing base, eliminating the need for additional side or rear openings, reducing the number of slots in the housing. The centralized end face layout also retains other mounting holes on the bottom, making the overall size smaller and installation more flexible. With the insertion slot and sealing slot on the same side, users can intuitively align them when inserting or removing parts, making assembly faster, reducing the misinsertion rate, and significantly improving daily use and maintenance efficiency.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0025] Definitions:

[0026] Electronic devices: These are devices composed of electronic components such as integrated circuits, transistors and / or vacuum tubes, which use electronic technology (including software technology) to function. They include electronic computers, mobile phones, tablets, smartwatches, smart glasses, portable game consoles, etc.

[0027] Mobile vehicles are devices that can move autonomously, automatically according to a control program, or under manual control, including manned aircraft, drones, cars, ships, and underwater vehicles.

[0028] Example

[0029] Combination Figures 1 to 3 This embodiment provides an RTK (Real-Time Kinematic) receiver, including a housing 1, a control circuit board 2, an RTK antenna module 3, and an interface module 4 disposed within the housing 1. The RTK antenna module 3 and the interface module 4 are electrically connected to the control circuit board 2. A corresponding recessed slot 5 communicating with the interface module 4 and a sealing groove 6 formed around the outer periphery of the housing 1 are formed on its end face. A sealing gasket 7 is correspondingly fitted inside the sealing groove 6, and the sealing groove 6 is at least partially in communication with the slot 5.

[0030] The RTK receiver described above has an annular sealing groove 6 on the end face of the outer shell, and a sealing gasket 7 is placed inside the groove, so that a complete sealing barrier is formed around the socket slot 5. The sealing groove 6 is partially connected to the socket slot 5, ensuring that the sealing gasket 7 can fit and fill the gap of the plug-in part, effectively preventing moisture and dust from entering the interface module 4.

[0031] In particular, the insertion slot 5 and the sealing slot 6 are both located on the end face of the housing base 1, eliminating the need for additional side or rear openings, reducing the number of slots in the housing. The centralized end face layout also preserves other mounting holes on the bottom, making the overall size smaller and installation more flexible. With the insertion slot 5 and the sealing slot 6 on the same side, users can intuitively align them when inserting or removing parts, making assembly faster and reducing the rate of misinsertion, thus significantly improving daily use and maintenance efficiency.

[0032] In this embodiment, the insertion slot 5 is configured as a rectangular notch, with the notch facing the same height as the sealing groove 6 and smoothly connected. The rectangular notch and the annular sealing groove 6 are at the same height and smoothly connected, allowing the sealing gasket 7 to seamlessly transition between them, avoiding dead angles and gaps at misalignments, and further improving the overall water and air barrier performance. Furthermore, the slotted structure with the same plane and height facilitates one-time mold or CNC milling processing, reducing secondary positioning and cutting processes, and lowering production costs.

[0033] Specifically, the socket slot 5 has an arc surface 8 on one side where the notch is located and a sloped surface 9 on the opposite side, so that the socket slot 5 is constructed as a whole to present an expanded shape suitable for plugging into the interface module 4. The arc surface 8 can provide smooth tangential contact after the external plug is inserted, guiding the external plug into the socket slot 5 in the correct direction. And the sloped surface 9 gradually fits against the plug shell as the insertion depth increases, achieving self-positioning and locking, and avoiding eccentricity or jamming.

[0034] It's worth mentioning that the outward expansion design gives the socket slot 5 a more dynamic visual effect, which is consistent with the overall design of the device. Furthermore, it facilitates the quick and error-controlled insertion and removal of external connectors into and out of the socket slot 5.

[0035] In this embodiment, the housing 1 includes a base 10 and a cover 11. The base 10 has a top opening, and the cover 11 is detachably screwed onto the top opening. The control circuit board 2 is mounted inside the base 10 via a base 12. The RTK antenna module 3 and interface module 4 are correspondingly attached to the control circuit board 2. As described above, the control circuit board 2 is mounted and fixed inside the base 10 via the base 12, effectively resisting vibration and impact, ensuring long-term stable operation of the components on the board under various harsh conditions.

[0036] In this embodiment, the end face is correspondingly formed on the cover 11, and a label 13 for recording product information is provided in the middle area of ​​the cover 11. It should be understood that a label area is reserved in the middle of the end face of the cover 11, where information such as serial number, production date, model, and factory number can be directly pasted, allowing users to quickly identify the product identity and version without disassembling the device.

[0037] The insertion slot 5 and the label are positioned on the same end face, avoiding each other. This staggered positioning prevents scratches or obstruction of the label during frequent insertion and removal, thus extending the lifespan of the label and markings.

[0038] Furthermore, multiple fixing nuts 14 are correspondingly provided on the end face. These fixing nuts 14 are used to tighten the end face, causing the relative position of the sealing groove 6 to change and compress the sealing gasket 7. Thus, by arranging multiple fixing nuts 14 on the end face, the positional variation of the sealing groove 6 can be controlled by adjusting the torque of the mounting screws, thereby precisely adjusting the compression degree of the sealing gasket 7. Compared to a fixed compression structure, the combination of fixing nuts 14 and mounting screws allows for on-site adjustment of tightness according to the sealing condition, adapting to different environmental conditions and changes in service life.

[0039] In this embodiment, the base 10 and the cap 11 cooperate to form a bottle cap shape, and a sealing ring 15 is fitted at the screw connection between the base 10 and the cap 11. By fitting the sealing ring 15 onto the cap 11, multiple compression seals are achieved during screw tightening, effectively preventing moisture, dust, and other contaminants from entering the interior.

[0040] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions that fall within the scope of this utility model's concept are protected by this utility model.
