Technical Field
[0001] This utility model belongs to the field of geographic surveying and mapping technology, and specifically relates to a portable geographic surveying and mapping device. Background Technology
[0002] In the field of geographic surveying, whether it's land planning, geological exploration, urban construction, or disaster monitoring, accurate geographic data is essential. Portable geographic surveying devices, due to their adaptability to complex field environments and ability to meet rapid on-site surveying needs, are gradually becoming the mainstream equipment in the industry. With increasing demands for surveying accuracy, traditional single-function surveying tools (such as GPS devices with only positioning capabilities or cameras that only acquire images) can no longer meet the needs of efficient operations. The market urgently needs portable devices that integrate multiple functions such as image acquisition, distance measurement, high-precision positioning, and data transmission. At the same time, the complex field surveying environment, where equipment often faces external interference such as dust, rain, and collisions, and where operators need to carry the equipment for extended periods, places higher demands on the protective performance and portability of the devices.
[0003] However, existing portable geographic mapping devices still have significant shortcomings. On the one hand, most devices have low functional integration, often requiring multiple independent devices (such as separate positioning devices, rangefinders, and image acquisition devices) to complete the entire mapping process. This not only increases the weight and cost of the equipment but also causes data transmission delays and difficulties in accurately matching data from different devices, resulting in low mapping efficiency and affecting the accuracy of the results. For example, some devices, although integrating positioning and image acquisition functions, lack a high-precision distance measurement module, requiring an additional laser rangefinder, and the data from both must be manually correlated, which is prone to errors.
[0004] On the other hand, existing devices fall short in balancing portability and protective performance. Some devices, in pursuit of protection, employ heavy, fixed outer shells. While these can withstand external interference, they significantly increase the weight of the equipment, making them inconvenient for prolonged handheld or carrying in the field. Other lightweight designs simplify the protective structure, making the outer shell susceptible to impact damage. Furthermore, in humid and dusty environments, internal precision modules (such as positioning modules and cameras) are easily corroded, shortening the equipment's lifespan. In addition, some devices have separate protective components from the main body, requiring separate storage of the protective shell. This not only increases the risk of loss but also adds to the operational steps, further reducing the convenience of surveying operations. Utility Model Content
[0005] The present invention aims to solve the problems of low functional integration and the need to use multiple devices in the existing portable geographic mapping devices, as well as the lack of balance between portability and protection. These devices are either bulky and inconvenient to carry or have poor protection that makes components easily damaged.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A portable geographic mapping device, comprising:
[0008] The mounting shell is a shell structure with an inverted U-shaped cross section, and an inverted U-shaped opening A is provided at the bottom of the mounting shell. A handle rod with both ends fixedly connected to the mounting shell is installed in the inverted U-shaped opening A, which is convenient for holding and carrying.
[0009] The geographic mapping module is installed inside and protrudes from the mounting housing. The geographic mapping module includes an ultra-wide-angle camera, a laser emitter installed on the top of the ultra-wide-angle camera housing, a global network module, and a centimeter-level RTK positioning module.
[0010] The protective housing engages with the mounting housing. The protective housing has an inverted U-shaped opening B corresponding to the inverted U-shaped opening A. The protective housing engages with the outer side of the mounting housing and the geographic mapping module to protect the mounting housing and the geographic mapping module, or engages with the bottom of the mounting housing to facilitate storage of the protective housing during geographic mapping.
[0011] As a preferred option, a centimeter-level RTK positioning module is used to acquire high-precision location information; a global network module is used to transmit and receive data; a laser emitter is used to emit laser pulses towards the target to measure distance; an ultra-wide-angle camera is used to acquire image information of the geographical environment; and the mounting shell is equipped with operation interfaces and display areas corresponding to each module.
[0012] Preferably, the global network module and the centimeter-level RTK positioning module are offset on both sides of the ultra-wide-angle camera, and the global network module and the centimeter-level RTK positioning module are respectively fixed to the mounting platform inside the mounting shell by mounting bracket A.

[0014] Preferably, the ultra-wide-angle camera is rotatably mounted onto mounting base B via a rotating connector at the bottom. The ultra-wide-angle camera with the adjusted angle is positioned and fixed by rotating the locking knob on the connector. Mounting base B is fixed on the mounting platform inside the mounting housing.
[0015] Preferably, the mounting housing has an opening slot at its center to provide space for the ultra-wide-angle camera and laser emitter.
[0016] Preferably, a mounting box A is provided on one side of the mounting housing, near the centimeter-level RTK positioning module. The mounting box A contains a battery module that provides power to the ultra-wide-angle camera, laser emitter, global network module, and centimeter-level RTK positioning module. The battery module uses a rechargeable lithium battery, and a charging interface is provided on the mounting housing.
[0017] Preferably, a mounting box B is provided on one side of the mounting housing, near the Global System for Mobile Communications (GSM) network module. The mounting box B contains a circuit board, through which the centimeter-level RTK positioning module, the GSM network module, the laser emitter, and the ultra-wide-angle camera are electrically connected. The circuit board is equipped with a data processing unit for processing and fusing the data collected by each module. The circuit board is electrically connected to the battery module.
[0018] Preferably, the mounting housing has slots on both sides that engage with the locking positions on the inner side of the protective housing.
[0019] Preferably, after the protective shell is snapped into place with the mounting shell, one end of the protective shell uses its own sealing structure to seal one side of the mounting shell, and the other end of the protective shell is fastened with a sealing plate, which seals the other side of the mounting shell through the detachable sealing plate.
[0020] Compared with the prior art, the technical effects and advantages of this utility model are:
[0021] This invention integrates four core surveying and mapping functions: image acquisition, distance measurement, high-precision positioning, and data transmission. It can independently complete the entire geographic surveying and mapping process without the need for additional equipment. This not only reduces the number and weight of equipment carried, but also avoids problems such as data transmission delays between multiple devices and errors in manual data association, making surveying and mapping operations more efficient and ensuring greater accuracy of results.
[0022] This utility model's mounting shell adopts a lightweight inverted U-shaped structure design, combined with an ergonomic handle, which greatly improves the convenience of holding and carrying, making it suitable for long-term mobile operations in the field. At the same time, the internal mounting platform provides a stable foundation for each module, and the components are reasonably arranged and firmly installed, reducing data deviations caused by component shaking during the surveying process. It ensures both portability and structural stability, meeting the usage needs in complex field environments.
[0023] The protective shell of this utility model can switch between "protection" and "storage" modes through snap-fit. When in use, it can fully enclose the mounting shell and the geographic mapping module to resist external interference such as dust, rain, and collisions. When not in use, it can be fixed under the mounting shell to prevent loss and without affecting the normal operation of the device. In addition, the double-end sealing design of the protective shell (with built-in sealing structure + detachable sealing plate) further improves the protective sealing performance, can adapt to harsh outdoor environments such as humid and dusty conditions, and effectively extend the service life of the internal precision module.
[0024] The operation interface of this utility model corresponds one-to-one with the function of each module, and the display area can view key data in real time, reducing the learning cost of operation; the ultra-wide-angle camera supports flexible angle adjustment and can be quickly fixed, which can be adapted to different surveying scenarios such as mountains, plains, and building surroundings, and the collection perspective can be adjusted without moving the entire device; at the same time, the rechargeable battery design and convenient maintenance structure (such as a removable sealing plate) make it easier to recharge the device in the field and simplify the later maintenance, further improving the overall user experience.

Detailed Implementation
[0034] 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.
[0035] The following combination Figures 1 to 8 This application will be described in further detail.
[0036] This application discloses a portable geographic mapping device, including a mounting shell 1, a geographic mapping module, and a protective shell 8;
[0037] The geographic mapping module is installed inside the mounting housing 1 and protrudes entirely from the mounting housing 1. It mainly consists of an ultra-wide-angle camera 4, a laser emitter 5 mounted on the top of the housing of the ultra-wide-angle camera 4, a global network module 6, and a centimeter-level RTK positioning module 7.
[0038] The ultra-wide-angle camera 4 is used to acquire image information of the geographical environment; its bottom is rotatably mounted on the mounting base B15 via the rotating connecting seat 14, and the mounting base B15 is fixed on the mounting platform 11 inside the mounting shell 1; the rotating connecting seat 14 is provided with a locking knob 16, and after the angle of the ultra-wide-angle camera 4 is adjusted, it can be positioned and fixed by the locking knob 16.
[0039] The laser emitter 5 is mounted on the top of the housing of the ultra-wide-angle camera 4 and is used to emit laser pulses toward the target to measure distance.
[0040] The global network module 6 is used to transmit and receive data; it is offset from the centimeter-level RTK positioning module 7 and is set on both sides of the ultra-wide-angle camera 4. It is fixed to the mounting platform 11 inside the mounting shell 1 by the mounting base A10 and can move through the through hole A12 on the mounting shell 1.
[0041] The centimeter-level RTK positioning module 7 is used to obtain high-precision location information; it is offset from the global network module 6 and set on both sides of the ultra-wide-angle camera 4, and is fixed to the mounting platform 11 inside the mounting shell 1 by the mounting bracket A10, and can be moved through the through hole B13 on the mounting shell 1.
[0042] The geographic mapping module achieves geographic mapping functions through the collaborative operation of multiple components: the ultra-wide-angle camera 4 is responsible for capturing image information of the geographic environment. Its bottom rotating connector 14 can drive the camera to flexibly adjust the angle. After determining the appropriate angle, tightening the locking knob 16 can fix the position and ensure accurate image acquisition angle; the laser emitter 5 is installed on the top of the ultra-wide-angle camera 4. It emits laser pulses to the target object and calculates the distance to the target object based on the laser round-trip time; the centimeter-level RTK positioning module 7 uses satellite signals to obtain the centimeter-level high-precision coordinates of the device's location; the global communication network module 6 undertakes the data transmission and reception tasks, transmitting the information collected by each component or receiving external commands; at the same time, the global communication network module 6 and the centimeter-level RTK positioning module 7 are staggered on both sides of the ultra-wide-angle camera 4 and fixed on the mounting platform 11 by the mounting base A10. They can also pass through the through holes A12 and B13 of the mounting shell 1 to ensure stable signal and secure component installation.
[0043] The geographic surveying module integrates four core functions: image acquisition, distance measurement, high-precision positioning, and data transmission. It can independently complete the entire geographic surveying process without requiring additional equipment, significantly reducing the barrier to entry and complexity of equipment setup. The high-precision location information provided by the centimeter-level RTK positioning module 7, combined with the precise distance measurement of the laser emitter 5, allows for accurate correlation between acquired images and geographic data, avoiding data discrepancies in traditional surveying and significantly improving the accuracy of surveying results. The adjustable angle design of the ultra-wide-angle camera 4, along with the quick-fix function of the locking knob 16, adapts to different surveying scenarios such as mountains, plains, and areas around buildings. The acquisition angle can be adjusted without moving the entire device, effectively improving operational efficiency. The staggered layout of the global network module 6 and the centimeter-level RTK positioning module 7 not only avoids signal interference between components and ensures stable operation of each module, but also reduces data deviation caused by component movement during surveying through the fixing of the mounting bracket A10, further ensuring the reliability of surveying data.
[0044] The mounting shell 1 has an inverted U-shaped cross-section and an inverted U-shaped opening A2 at the bottom. A handle rod 3 is installed inside the inverted U-shaped opening A2. Both ends of the handle rod 3 are fixedly connected to the mounting shell 1, making it easy for the operator to hold the device and improving its portability.
[0045] The mounting shell 1 adopts an inverted U-shaped cross-section structure, which significantly reduces weight while ensuring its own structural strength, making it easy to carry and operate. The inverted U-shaped opening A2 at the bottom provides space for the installation of the handle rod 3 without affecting the overall sealing of the device. The two ends of the handle rod 3 are fixedly connected to the mounting shell 1, which conforms to the ergonomic design. Operators can easily hold it with one hand or carry it with both hands, making it especially suitable for scenarios such as field surveying and mapping. It effectively solves the problems of large size and difficult transportation of traditional surveying devices, and significantly improves the portability of the device.
[0046] The mounting shell 1 is equipped with operation interfaces and display areas corresponding to each module of the geographic surveying module, which facilitates the operation of the device and the viewing of data.
[0047] The mounting shell 1 has operation interfaces corresponding to each module of the geographic surveying module, allowing operators to quickly find and operate the corresponding functions without having to memorize complex button logic, reducing the learning cost and enabling even beginners to get started quickly. The display area can show key data in the surveying process in real time, such as location coordinates, measurement distance, and battery level. Operators can monitor the device's working status at any time without connecting to external devices, making it easy to promptly identify and adjust surveying parameters. For example, if a positional deviation is detected, the RTK module can be calibrated immediately, effectively improving surveying efficiency.
[0048] The mounting housing 1 has through holes A12 and B13, which are used to allow the Global System for Mobile Communications (GSM) module 6 and the centimeter-level RTK positioning module 7 to pass through.
[0049] The insertion holes A12 and B13 of the mounting housing 1 provide movable channels for the Global Network Module 6 and the centimeter-level RTK positioning module 7, respectively. This allows the two modules to be finely adjusted in position according to the strength of the signal in the field without being detached from the mounting housing 1. For example, in areas with weak signals, the module can be slightly pulled to adjust the receiving angle, thereby improving the stability of signal reception and ensuring that data acquisition and transmission are not affected. At the same time, the design of the insertion holes avoids the modules being completely exposed, which can reduce the direct damage to the modules caused by dust and collisions. It protects the components without affecting their normal function, achieving a balance between protection and functionality.
[0050] An opening slot 17 is provided at the center of the mounting housing 1 to provide space for the ultra-wide-angle camera 4 and the laser emitter 5 to adjust their angles and operate normally.
[0051] The opening slot 17 at the center of the mounting housing 1 precisely matches the working requirements of the ultra-wide-angle camera 4 and the laser emitter 5, providing ample space for the ultra-wide-angle camera 4 to adjust its angle, avoiding collisions with the mounting housing 1 when the camera rotates, and ensuring that the camera can be flexibly adjusted within the maximum angle range to meet the image acquisition needs of different scenarios. At the same time, the opening slot 17 also clears obstacles for the laser emitter 5 to emit laser pulses, preventing the mounting housing 1 from blocking the laser, ensuring the accuracy of laser ranging, and ensuring that the camera and the laser emitter 5 can work together efficiently without affecting the overall surveying process.
[0052] The mounting shell 1 has slots 21 on both sides, which are used to engage with the slots 20 on the inner side of the protective shell 8 to ensure the stable installation of the protective shell 8.
[0053] The slots 21 on both sides of the mounting shell 1 precisely engage with the locking positions 20 on the inner side of the protective shell 8, enabling quick snap-fit fixing of the protective shell 8 and the mounting shell 1. Without the need for screws or other tools, operators can complete the installation and removal of the protective shell 8 manually in a short time, greatly improving the ease of operation. This snap-fit structure is extremely stable. Even in bumpy outdoor environments, such as when walking with the device in mountainous terrain, the protective shell 8 will not fall off, always providing reliable protection for the mounting shell 1 and the geographic mapping module, ensuring the normal use of the device in complex environments.
[0054] Mounting box A18 is located on one side of mounting shell 1 and close to centimeter-level RTK positioning module 7. Mounting box A18 contains a battery module, which uses a rechargeable lithium battery to provide power to ultra-wide-angle camera 4, laser emitter 5, global network module 6 and centimeter-level RTK positioning module 7. Mounting shell 1 is also equipped with a charging interface that matches the battery module.
[0055] The mounting box A18 is positioned close to the centimeter-level RTK positioning module 7, shortening the power supply distance between the battery module and the RTK positioning module, reducing power transmission loss, and providing continuous and stable power support for the RTK positioning module, which has extremely high requirements for power supply stability, thus avoiding a decrease in positioning accuracy due to unstable power supply. The built-in rechargeable lithium battery is reusable, reducing consumable costs. The charging interface on the mounting shell 1 allows operators to recharge the battery in the field using devices such as power banks and vehicle chargers, solving the problems of short battery life and cumbersome replacement of traditional dry batteries, and significantly extending the field working time of the device. At the same time, the mounting box A18 provides an independent protective space for the battery module, preventing the battery from directly contacting other modules, reducing the risk of short circuits and collisions, and improving the safety of the device.
[0056] Mounting box B19 is located on one side of mounting shell 1 and close to the global network module 6. Inside mounting box B19 is a circuit board, which is electrically connected to the battery module. The centimeter-level RTK positioning module 7, global network module 6, laser emitter 5, and ultra-wide-angle camera 4 are electrically connected through the circuit board. The circuit board is also equipped with a data processing unit for processing and fusing the data collected by each module.
[0057] The mounting box B19 is positioned close to the Global Communicator Network Module 6, shortening the data transmission line between the circuit board and the network module, reducing data latency, and ensuring that image, distance, and location data collected by each module can be quickly transmitted to the data processing unit on the circuit board, improving data processing efficiency. The data processing unit can fuse and analyze the data collected by each module, generating complete geographic mapping results on-site without relying on an external computer, such as topographic maps with precise coordinates, meeting real-time mapping needs and significantly improving work efficiency. The mounting box B19 also provides a sealed protective environment for the circuit board, effectively preventing dust and moisture from corroding the circuit, reducing the probability of failure, and allowing access to the circuit board by simply opening the relevant components during later maintenance, reducing maintenance difficulty and cost.
[0058] The mounting shell 1 contains an mounting platform 11, which provides basic support for fixing the various components of the geographic mapping module.
[0059] The mounting platform 11 inside the mounting housing 1 provides a unified and flat reference surface for the installation of various components of the geographic mapping module, ensuring that components such as mounting bracket A10 and mounting bracket B15 can be accurately fixed. This ensures the accurate installation position of components such as the ultra-wide-angle camera 4, laser emitter 5, global network module 6, and centimeter-level RTK positioning module 7, avoiding functional deviations caused by installation offsets, such as RTK module offset affecting positioning accuracy or camera offset causing image misalignment. At the same time, the mounting platform 11 separates the installation space of each module, avoiding wear caused by direct contact and friction between components. It also facilitates the organization of the connection lines between each component and the circuit board, making the internal structure of the device neater and allowing for quick location of corresponding lines during later maintenance, thus reducing the difficulty of maintenance.
[0060] The protective shell 8 is engaged with the mounting shell 1. The protective shell 8 is provided with an inverted U-shaped opening B9 corresponding to the inverted U-shaped opening A2. The protective shell 8 is engaged with the outer side of the mounting shell 1 and the geographic mapping module to protect the mounting shell 1 and the geographic mapping module, or it is engaged with the bottom of the mounting shell 1 so that the protective shell 8 can be stored during geographic mapping.
[0061] The protective housing 8 is snapped onto the outer side of the mounting housing 1 and the geographic mapping module to protect them from damage caused by the external environment. The protective housing 8 is also snapped onto the bottom of the mounting housing 1 so that it can be stored away during geographic mapping without affecting the normal operation of the device.
[0062] The storage mode of the protective shell 8, which is snapped onto the underside of the mounting shell 1, completely solves the problem of traditional protective shells needing to be stored separately and being easily lost. During surveying operations, there is no need to find an extra storage location; the protective shell can be stored directly under the mounting shell 1, greatly improving the portability of the device. After storage, the protective shell 8 does not occupy extra space, does not affect the comfort of the operator holding the device, and does not obstruct the signal reception, image acquisition, and laser emission functions of the geographic surveying module, ensuring that surveying work can be carried out normally without interference, saving operators a lot of time in organizing and storing the protective shell.

[0064] After the protective housing 8 is engaged and positioned with the mounting housing 1, one end of the protective housing 8 is sealed to one side of the mounting housing 1 using its own sealing structure, and the other end of the protective housing 8 is fastened with a sealing plate 22. The other side of the mounting housing 1 can be sealed by the detachable sealing plate 22, further improving the protective sealing performance.
[0065] The protective housing 8 has a built-in sealing structure at one end that can quickly and effectively seal one side of the mounting housing 1 without additional operation, thus improving protection efficiency. The detachable sealing plate 22 attached to the other end can flexibly seal the other side of the mounting housing 1, forming a double-ended sealed protection. This further prevents dust, moisture and other impurities from entering the interior of the mounting housing 1, making it particularly suitable for humid and dusty field surveying environments, significantly improving the protective sealing performance of the device. At the same time, the detachable sealing plate 22 also provides convenience for later maintenance. When it is necessary to maintain the battery module in the mounting box A18 or the circuit board in the mounting box B19, only the sealing plate 22 needs to be removed, without removing the entire protective housing 8, reducing maintenance difficulty and time costs.
[0066] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
