Description

Technical Field

[0001] This utility model relates to the technical field of surveying equipment, and more specifically, to a multi-mode surveying equipment. Background Technology

[0002] Laser scanning mapping (SLAM) and real-time differential positioning (RTK) are both core technologies of modern high-precision surveying equipment. Laser SLAM technology uses lidar to perceive the surrounding environment and achieves real-time positioning and map building for the equipment itself. RTK technology, on the other hand, receives correction signals from satellite navigation systems to achieve absolute positioning with centimeter-level accuracy. Surveying equipment that integrates these two technologies can achieve high-precision, continuous 3D measurement and modeling in various environments, including indoors and outdoors, with and without satellite signals.

[0003] In the prior art, Chinese patent CN220820222U discloses a novel handheld laser scanner, including a handheld radar assembly and a handle with a built-in battery. The handheld radar assembly has a laser radar at its top and a male connector holder at its bottom, containing a male connector for connection to the laser radar. The handle contains a female connector holder, with a female connector holder for connection to the battery on one side and a battery latch on the opposite side. When the handheld radar assembly is mounted on the handle, the male connector holder is engaged with the female connector holder, the male connector connects to the female connector holder, and the handheld radar assembly is pressed against the battery latch. However, this laser scanner is only suitable for handheld measurements in narrow spaces while walking smoothly, and cannot be used in open areas requiring measurements on a central pole, thus lacking compatibility with various application scenarios. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies that are only applicable to handheld measurement and cannot be compatible with multiple application scenarios. It provides a multi-mode surveying device that allows the main unit of the device to quickly switch between two modes: centering pole frame measurement and handheld measurement without disassembling the core components, thereby adapting to a variety of application scenarios.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A multi-mode surveying device is provided, including a main housing, a first adapter, a second adapter, a centering rod, and a handle. The main housing integrates surveying functional components. The first adapter and the second adapter are both located at the bottom of the main housing. The installation height of the first adapter is lower than that of the second adapter. The first adapter has a clearance structure for exposing the second adapter. The main housing can be detachably connected to the handle via the first adapter or to the centering rod via the second adapter.

[0006] This multi-mode surveying device allows users to quickly switch between different modes depending on the surveying scenario. For handheld measurements, the handle is connected to a first adapter with a low-lying, clearance structure on the bottom of the main housing, creating a comfortable handheld mode. For frame-mounted measurements, the handle can be connected to the frame-mounted pole without disassembling the handle; the main housing is then securely mounted on the pole, quickly switching to frame-mounted mode. Both modes allow for surveying of the surrounding environment using the surveying components. This invention enables rapid switching between frame-mounted and handheld measurement modes without disassembling core components, adapting to various application scenarios.

[0007] Furthermore, a buckle is provided at the bottom of the first adapter, and the grip handle includes a connecting part and a grip part that are connected to each other. A slot is provided at the top of the connecting part, and the buckle cooperates with the slot. By providing a buckle at the bottom of the first adapter and a corresponding slot at the top of the connecting part of the grip handle, quick docking and locking between the main unit housing and the grip handle are achieved, ensuring a stable and reliable connection between the main unit housing and the grip handle.

[0008] Furthermore, the bottom of the buckle is provided with a spring-loaded groove, in which a movable buckle and a first elastic element are disposed. The first elastic element is disposed at the bottom of the movable buckle and drives the movable buckle to reciprocate in a direction parallel to the axis of the grip handle. The movable buckle can be embedded in the spring-loaded groove. By the movable buckle being driven by the first elastic element to embed into the spring-loaded groove of the buckle, a self-locking mechanism is formed, realizing automatic locking when the main unit is connected to the grip handle. This effectively prevents the device from accidentally loosening due to shaking or operation during handheld measurement, improving the connection reliability and operational safety in handheld mode.

[0009] Furthermore, the grip handle also includes a snap-lock button, which is slidably disposed on the connecting part and protrudes from the connecting part at one end. The movement direction of the snap-lock button is perpendicular to the axis of the grip handle. The snap-lock button has a first inclined surface, and the movable buckle has a second inclined surface that abuts against the first inclined surface. By setting the snap-lock button with the first inclined surface to cooperate with the second inclined surface on the movable buckle, a single-finger press operation perpendicular to the grip direction can drive the movable buckle out of the locked position, providing an intuitive, effortless, and fast unlocking method and improving the installation and disassembly efficiency of the device in handheld mode.

[0010] Furthermore, the spring-loaded button includes a second elastic element, a movable element, and a fixing element. The fixing element is fixedly connected to the connecting part, and the connecting part has a guide groove. The movable element is slidably disposed in the guide groove. The two ends of the second elastic element abut against the movable element and the fixing element, respectively. The first inclined surface is disposed on the movable element. By setting a spring-loaded button composed of a fixing element, a movable element with a guide groove, and a second elastic element, the sliding trajectory of the movable element is constrained by the guide groove, ensuring the stability of the inclined surface transmission. At the same time, the second elastic element provides an automatic reset function after the pressing pressure is released, thereby achieving a smooth and reliable locking action.

[0011] Furthermore, the buckle is provided with a first fixing groove, and a first fastening screw for connecting to the main unit housing is disposed in the first fixing groove. This design, by providing a first fixing groove on the buckle of the first adapter and using a first fastening screw for connection, achieves a firm fixation between the first adapter and the main unit housing, ensuring connection strength, and also avoids the impact of external protruding screws on the grip or the aesthetics of the device.

[0012] Furthermore, the second adapter has a threaded portion that is threadedly connected to the centering rod. By providing a threaded portion in the second adapter, it can be directly threadedly connected to the centering rod. This connection method is simple in structure, reliable in tightening, and enables quick installation and disassembly between the main housing and the centering rod.

[0013] Furthermore, a second fixing groove is provided at the top of the threaded portion, and a second fastening screw for connecting to the main housing is provided in the second fixing groove. By providing a second fixing groove at the top of the threaded portion and using a second fastening screw to securely connect the second adapter to the main housing from the inside, sufficient connection strength is provided to resist torque and vibration during use.

[0014] Furthermore, a positioning part is provided on the outer periphery of the threaded portion, and a positioning groove is provided on the bottom of the main housing, with the positioning part abutting against the positioning groove. By providing a positioning part on the outer periphery of the second adapter and configuring a matching positioning groove on the bottom of the main housing, precise circumferential positioning is provided for the connection between the two, ensuring the structural stability of the equipment in the centering rod measurement mode.

[0015] Furthermore, a sealing ring is provided between the bottom of the positioning part and the centering rod. Adding a sealing ring at the connection interface between the positioning part and the centering rod effectively fills any microscopic gaps that may exist in the threaded connection, forming a reliable sealing barrier. This prevents rainwater, dust, and other contaminants from entering the equipment, improving the equipment's protection level in complex outdoor environments.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. It enables quick switching between multiple surveying modes. By setting up a first adapter and a second adapter, and using an avoidance structure to expose the second adapter, the main unit housing can be quickly installed on the grip handle or centering rod. It can flexibly switch between centering rod stand measurement mode and handheld measurement mode without disassembling the core components. 2. The structure is compact and the connection is reliable. It adopts a mechanical connection method with buckle and slot, combined with elastic elements and inclined structure, which realizes quick disassembly and assembly and stable locking of the handle, improving the ease of operation of the device in handheld mode. 3. The second adapter is equipped with a positioning part and a sealing ring to ensure accurate positioning and waterproof and dustproof effect when connected with the centering rod, which is suitable for high-precision surveying operations in complex outdoor environments.

[0021] Example 1 This embodiment is a first embodiment of a multi-mode surveying and mapping device, including a main housing 100, a first adapter 200, a second adapter 300, a centering rod 400, and a grip handle 500. The main housing 100 integrates a surveying and mapping functional component 600. The first adapter 200 and the second adapter 300 are both located at the bottom of the main housing 100. The installation height of the first adapter 200 is lower than that of the second adapter 300. The first adapter 200 is provided with a clearance structure 210 for exposing the second adapter 300. The main housing 100 can be detachably connected to the grip handle 500 via the first adapter 200 or to the centering rod 400 via the second adapter 300.

[0022] This utility model's multi-mode surveying and mapping equipment allows users to quickly switch between operating modes according to the needs of the surveying and mapping scenario. For example... Figure 1 , Figure 3 , Figure 7 As shown, when handheld measurement is required, the handle 500 is connected to the first adapter 200, which is located at a lower position on the bottom of the main housing 100 and has a clearance structure 210, thus forming a handheld mode that is easy to hold. When the centering rod 400 is to be erected for measurement, there is no need to disassemble the handle 500. The second adapter 300 exposed by the clearance structure 210 is used to connect it to the centering rod 400, and the main housing 100 is then securely mounted on the centering rod 400, thus quickly switching to the erected mode. In both modes, the surveying function component 600 can be used to survey the surrounding environment. This invention allows the main housing 100 to quickly switch between the centering rod 400 erected measurement and the handle handheld measurement modes without disassembling the core components, thus adapting to various application scenarios.

[0023] like Figures 2-4 As shown, in this embodiment, the first adapter 200 has a buckle 220 at its bottom, and the grip handle 500 includes a connecting part 510 and a grip part 520 connected to each other. The top of the connecting part 510 has a slot 511, and the buckle 220 cooperates with the slot 511. By providing a buckle 220 at the bottom of the first adapter 200 and a corresponding slot 511 at the top of the connecting part 510 of the grip handle 500, quick docking and locking between the main unit housing 100 and the grip handle 500 are achieved, ensuring a stable and reliable connection between the main unit housing 100 and the grip handle 500.

[0024] like Figure 4 As shown, the buckle 220 has a spring-loaded groove 221 at its bottom. A movable buckle 530 and a first elastic element 540 are located in the groove 511. The first elastic element 540 is positioned at the bottom of the movable buckle 530 and drives the movable buckle 530 to reciprocate in a direction parallel to the axis of the handle 500. The movable buckle 530 can be inserted into the spring-loaded groove 221. By engaging the movable buckle 530 in the spring-loaded groove 221 of the buckle 220 under the drive of the first elastic element 540, a self-locking mechanism is formed. This achieves automatic locking when the main unit is connected to the handle 500, effectively preventing accidental disengagement of the device due to shaking or operation during handheld measurement, thus improving the connection reliability and operational safety in handheld mode.

[0025] like Figure 2As shown, the buckle 220 in this embodiment is provided with a first fixing groove, and a first fastening screw 222 for connecting to the main housing 100 is provided in the first fixing groove. This design, by providing a first fixing groove on the buckle 220 of the first adapter 200 and using the first fastening screw 222 for connection, achieves a firm fixation between the first adapter 200 and the main housing 100, ensuring connection strength, and also avoiding the impact of external protruding screws on the grip feel or the aesthetics of the device.

[0026] In this embodiment, the mapping function component 600 integrated inside the main unit housing 100 includes a laser scanning mapping component and a real-time differential positioning component. The laser scanning mapping component is used to perceive the surrounding environmental features through lidar to achieve real-time positioning and map construction of the device; the real-time differential positioning component is used to receive correction signals from the satellite navigation system to achieve absolute positioning with centimeter-level accuracy. The two work together to enable the multi-mode mapping equipment to achieve continuous, high-precision three-dimensional measurement and modeling in various environments, including indoors, outdoors, and with or without satellite signals.

[0027] Example 2 This embodiment is the second embodiment of a multi-mode surveying and mapping equipment. This embodiment is similar to the first embodiment, except that, as shown in the following... Figure 5 , Figure 6 As shown, the grip handle 500 also includes a spring-loaded button, which is slidably disposed on the connecting part 510 and protrudes from the connecting part 510 at one end. The movement direction of the spring-loaded button is perpendicular to the axis of the grip handle 500. The spring-loaded button is provided with a first inclined surface 561, and the movable buckle 530 is provided with a second inclined surface 531 that abuts against the first inclined surface 561. By setting the spring-loaded button with the first inclined surface 561 to cooperate with the second inclined surface 531 on the movable buckle 530, a single-finger press operation perpendicular to the grip direction can drive the movable buckle 530 out of the locked position, providing an intuitive, effortless, and fast unlocking method and improving the installation and disassembly efficiency of the device in handheld mode.

[0028] like Figure 5 , Figure 6As shown, the snap button in this embodiment includes a second elastic element 550, a movable element 560, and a fixing element 570. The fixing element 570 is fixedly connected to the connecting part 510. The connecting part 510 has a guide groove. The movable element 560 is slidably disposed in the guide groove. The two ends of the second elastic element 550 abut against the movable element 560 and the fixing element 570, respectively. A first inclined surface 561 is disposed on the movable element 560. When the user presses the snap button, the movable element 560 slides in a direction perpendicular to the handle axis under the constraint of the guide groove. The first inclined surface 561 on it pushes the second inclined surface 531 on the movable buckle 530, forcing the movable buckle 530 to compress the first elastic element 540 and move downward, thereby disengaging it from the snap groove 221 of the latch 220 and unlocking it. When the pressing pressure is released, the second elastic element 550 pushes the movable element 560 to reset, and the first elastic element 540 pushes the movable buckle 530 to reset upward and re-embed it in the snap groove 221, completing the automatic locking. By setting a spring-loaded button consisting of a fixed member 570, a movable member 560 with a guide groove, and a second elastic member 550, the guide groove constrains the sliding trajectory of the movable member 560, ensuring the stability of the inclined plane transmission. At the same time, the second elastic member 550 provides an automatic reset function after the pressure is released, thereby achieving a smooth and reliable locking action.

[0029] Example 3 This embodiment is the third embodiment of a multi-mode surveying and mapping device. This embodiment is similar to the first embodiment, except that, as shown in the following... Figure 7 , Figure 8 As shown, the second adapter 300 has a threaded portion 310, which is threadedly connected to the centering rod 400. By providing the threaded portion 310 in the second adapter 300, it can be directly threadedly connected to the centering rod 400. This connection method is simple in structure and reliable in tightening, realizing quick installation and disassembly between the main housing 100 and the centering rod 400.

[0030] like Figure 7 , Figure 8 As shown, a positioning part 320 is provided on the outer periphery of the threaded part 310, and a positioning groove 110 is provided on the bottom of the main housing 100. The positioning part 320 abuts against the positioning groove 110. By providing a positioning part 320 on the outer periphery of the second adapter 300 and configuring a matching positioning groove 110 on the bottom of the main housing 100, precise circumferential positioning is provided for the connection between the two, ensuring the structural stability of the equipment in the centering rod 400 measurement mode.

[0031] like Figure 7 , Figure 8As shown, a sealing ring 410 is provided between the bottom of the positioning part 320 and the centering rod 400. The addition of the sealing ring 410 at the connection interface between the positioning part 320 and the centering rod 400 effectively fills the microscopic gaps that may exist in the threaded connection, forming a reliable sealing barrier that can prevent rainwater, dust and other pollutants from entering the equipment and improve the protection level of the equipment in complex outdoor environments.

[0032] A second fixing groove is provided at the top of the threaded portion 310, and a second fastening screw 311 is provided in the second fixing groove to connect with the main housing 100. The second fixing groove at the top of the threaded portion 310 and the second fastening screw 311 securely connect the second adapter 300 to the main housing 100 from the inside, providing sufficient connection strength to resist torque and vibration during use.

[0033] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0034] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
