Description
Technical Field
[0001] This utility model belongs to the technical field of marine surveying and route planning equipment, specifically, it relates to a multifunctional handheld terminal device for marine surveying and route planning. Background Technology
[0002] Traditional marine mapping equipment typically consists of multiple independent modules, such as single-beam / multi-beam depth sounders, GNSS positioning terminals, inertial navigation systems (IMUs), and electronic chart display and information systems (ECDIS). These devices are often bulky, complex to operate, and require fixed installation on ships, making it difficult to meet the flexible operational needs in near-shore, shallow water, or emergency scenarios.
[0003] Currently, handheld marine mapping equipment on the market faces the following technical bottlenecks:
[0004] In situations involving ship swaying or rough seas, traditional handheld devices lack effective shock absorption mechanisms, leading to data drift and requiring manual correction later, which is inefficient.
[0005] The brackets or handles of existing equipment are mostly fixed designs, which cannot be quickly adapted to switching between multiple scenarios such as handheld, desktop placement or shipboard installation, thus affecting operational flexibility;
[0006] To address the aforementioned issues, this application proposes a multifunctional handheld terminal device for marine surveying and route planning. Utility Model Content
[0007] In view of the problems in the related technologies, this utility model proposes a multifunctional handheld terminal device for marine surveying and route planning, so as to overcome the above-mentioned technical problems existing in the existing related technologies.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:
[0009] A multifunctional handheld terminal device for marine surveying and route planning includes a surveying equipment terminal, a mounting base rotatably connected to the rear of the surveying equipment terminal, three Z-shaped handles mounted on the bottom of the mounting base, and an operation screen mounted on the front of the surveying equipment terminal.
[0010] An angle clamping mechanism includes a fixing ring, which is fixedly installed on the rear side of the surveying equipment terminal. A mounting plate is rotatably installed on the rear side of the surveying equipment terminal, and a mounting base is fixedly installed on the mounting plate.
[0011] The shock absorption mechanism includes a shock absorber, which is fixedly installed at the bottom of the mounting base, and three Z-shaped handles are slidably installed at the bottom of the shock absorber.
[0012] Preferably, the angle clamping mechanism further includes multiple clamping heads, which are fixedly installed on the inner side of the fixing ring, and multiple protrusions are installed on the side of the mounting plate, with the protrusions cooperating with the clamping heads.
[0013] The buckle between the protruding head and the locking head allows for angular positioning between the mounting plate and the fixing ring, facilitating angular positioning between the Z-shaped handle and the surveying equipment terminal, while also enabling easy rotational adjustment.
[0014] Preferably, the shock absorption mechanism further includes a piston plate, which is slidably mounted on the inner wall of the shock absorber. Three Z-shaped handles are rotatably mounted on the bottom of the piston plate, and a return spring is fixedly mounted on the top of the piston plate. The top end of the return spring is fixedly connected to the top inner wall of the shock absorber.
[0015] The Z-shaped handles are connected to the piston plate by rotation, allowing the three Z-shaped handles to rotate at an angle. This makes it easy to hold the device by hand and also allows for stable placement on a table. The piston plate is connected to the shock absorber by sliding, and the return spring provides a return effect to the piston plate, thus creating a shock absorption effect between the Z-shaped handles and the shock absorber.
[0016] Preferably, the piston plate has multiple guide holes, and multiple arc-shaped spring pieces are fixedly installed at the bottom of the piston plate. An adjustment plate is fixedly installed at one end of each arc-shaped spring piece, and the adjustment plate cooperates with the corresponding guide hole.
[0017] By setting multiple guide holes, it is possible to facilitate energy conversion when the piston plate moves, and reduce the energy consumption of movement when the piston plate moves. At the same time, when the piston plate retracts, the adjustment plate forms a one-way blockage of multiple guide holes, further reducing the rebound force, thereby creating a damping effect, making the shock absorption effect between the shock absorber and the Z-shaped handle stronger.
[0018] Preferably, each of the three Z-shaped handles is fitted with a splined shaft, and the same limiting plate is slidably connected to the three splined shafts.
[0019] By sliding the spline shaft to the limiting plate, the limiting plate can fix the lateral angle of the Z-shaped handle through the spline shaft, thereby forming a stable support between the three Z-shaped handles.
[0020] Preferably, a baffle is fixedly installed at the bottom end of the spline shaft, and a top spring is fixedly installed at the top of the limiting plate, with the top end of the top spring being fixedly connected to the bottom end of the shock absorber.
[0021] The top spring allows the limiting plate to be pushed onto the spline shaft and positioned by the baffle, thus enabling the limiting plate to stably fix the angle of the Z-shaped handle.
[0022] In summary, the technical effects and advantages of this utility model are as follows:
[0023] 1. Angle clamping and quick adjustment mechanism
[0024] The convex head-clamping structure: the convex head on the mounting plate and the clamping head of the fixing ring have multiple positions for locking, so that the angle of the Z-shaped handle and the surveying equipment terminal can be infinitely adjusted (0°~180°), which can adapt to various postures such as hand-held, desktop placement or ship-mounted fixation.
[0025] 2. Multi-stage vibration reduction and damping optimization
[0026] Unidirectional damping shock absorption system:
[0027] The guide hole of the piston plate and the adjusting plate form a one-way valve effect: when pressed down, the airflow quickly releases pressure through the guide hole, and when rebounding, the adjusting plate closes the guide hole, and the deformation of the arc-shaped spring generates damping, reducing rebound vibration by more than 70%.
[0028] Double buffering with return spring and arc-shaped spring: the spring absorbs high-frequency vibration, and the spring suppresses low-frequency shaking, making it suitable for unstable environments such as ship decks.
[0029] Spline shaft limiting structure: Through the sliding cooperation between the limiting plate and the spline shaft, the unfolding angle of the three Z-shaped handles can be locked with one click, forming a triangular stable support to prevent the equipment from tipping over.
[0030] 3. Multi-scenario adaptive design
[0031] The Z-shaped handle is three-axis adjustable and has a 120° distribution for ergonomic grip. When the handle is rotated to a horizontal position, it is fixed to form a support by the limiting plate 7. The handle can be folded and stored, and is attached to the ship's side by shock-absorbing cylinder. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0040] Reference Figure 1-5 A multi-functional handheld terminal device for marine surveying and route planning includes a surveying equipment terminal 1, a mounting base 2 rotatably connected to the rear of the surveying equipment terminal 1, three Z-shaped handles 3 mounted on the bottom of the mounting base 2, an operation screen 10 mounted on the front of the surveying equipment terminal 1, and the surveying equipment terminal 1 is equipped with a single-beam depth sounder and RTK, a multi-beam sonar and IMU, GNSS and electronic chart, and a Beidou terminal and tide module.
[0041] Angle clamping mechanism 4 includes a fixing ring 41, which is fixedly installed on the rear side of the surveying equipment terminal 1. A mounting plate 42 is rotatably installed on the rear side of the surveying equipment terminal 1, and a mounting base 2 is fixedly installed on the mounting plate 42.
[0042] The shock absorption mechanism 5 includes a shock absorber 51, which is fixedly installed at the bottom of the mounting base 2, and three Z-shaped handles 3 are slidably installed at the bottom of the shock absorber 51.
[0043] Reference Figure 2 and Figure 3 The angle clamping mechanism 4 also includes multiple clamp heads 43, which are fixedly installed on the inner side of the fixing ring 41. Multiple protrusions 44 are installed on the side of the mounting plate 42. The protrusions 44 and the clamp heads 43 cooperate with each other. Through the buckling between the protrusions 44 and the clamp heads 43, the mounting plate 42 and the fixing ring 41 are angularly positioned, which facilitates the angular positioning between the Z-shaped handle 3 and the surveying equipment terminal 1, and also facilitates rotational adjustment.
[0044] Reference Figure 4The damping mechanism 5 also includes a piston plate 52, which is slidably mounted on the inner wall of the damping cylinder 51. Three Z-shaped handles 3 are rotatably mounted on the bottom of the piston plate 52. A return spring 53 is fixedly mounted on the top of the piston plate 52, and the top end of the return spring 53 is fixedly connected to the top inner wall of the damping cylinder 51. The piston plate 52 has multiple guide holes 54, and multiple arc-shaped spring pieces 56 are fixedly mounted on the bottom of the piston plate 52. An adjusting plate 55 is fixedly mounted on one end of each arc-shaped spring piece 56. The adjusting plate 55 cooperates with the corresponding guide holes 54. Through the setting of multiple guide holes 54, it is possible to facilitate the energy conversion of the piston plate 52 during movement, and the energy is generated in the piston plate 52. 2. Reduce movement energy consumption during movement. At the same time, when the piston plate 52 retracts, the adjusting plate 55 forms a one-way blockage of multiple guide holes 54, further reducing the rebound force and thus creating a damping effect. This makes the shock absorption effect between the shock absorber 51 and the Z-shaped handle 3 stronger. Through the rotational connection between the Z-shaped handle 3 and the piston plate 52, the three Z-shaped handles 3 can rotate at an angle, which makes it easy to hold the device and also allows for stable placement on a table. Furthermore, through the sliding connection between the piston plate 52 and the shock absorber 51, the return spring 53 resets the piston plate 52, thus creating a shock absorption and buffering effect between the Z-shaped handle 3 and the shock absorber 51.
[0045] Reference Figure 4 Each of the three Z-shaped handles 3 is fitted with a splined shaft 6, and the same limiting plate 7 is slidably connected to the three splined shafts 6. A baffle 9 is fixedly installed at the bottom end of the splined shaft 6, and a top spring 8 is fixedly installed at the top of the limiting plate 7. The top end of the top spring 8 is fixedly connected to the bottom end of the shock absorber 51. The splined shaft 6 is slidably connected to the limiting plate 7, so that the limiting plate 7 can fix the lateral angle of the Z-shaped handle 3 through the splined shaft 6, thereby forming a stable support between the three Z-shaped handles 3. Through the setting of the top spring 8, the limiting plate 7 can be pushed to move onto the splined shaft 6 and positioned by the baffle 9, so that the limiting plate 7 can stably fix the angle of the Z-shaped handle 3.
[0046] Working principle: During operation, the three Z-shaped handles 3 are held by hand to operate the surveying equipment terminal 1. Simultaneously, the latching of the protrusion 44 and the locking head 43 creates an angled positioning between the mounting plate 42 and the fixing ring 41, facilitating the angled positioning of the Z-shaped handles 3 and the surveying equipment terminal 1, and also allowing for easy rotational adjustment. The spline shaft 6 is slidably connected to the limiting plate 7, allowing the limiting plate 7 to fix the lateral angle of the Z-shaped handles 3 via the spline shaft 6, thus providing stable support among the three Z-shaped handles 3. The top spring 8 pushes the limiting plate 7 onto the spline shaft 6, and the baffle 9 provides positioning, ensuring the limiting plate 7 stably fixes the angle of the Z-shaped handles 3. Multiple guide holes 54 facilitate energy conversion during the movement of the piston plate 52, reducing energy consumption during movement. When the piston plate 52 retracts, the adjusting plate 55 forms a one-way blockage of multiple guide holes 54, further reducing the rebound force and thus creating a damping effect. This makes the shock absorption effect between the shock absorber 51 and the Z-shaped handle 3 stronger. Through the rotational connection between the Z-shaped handle 3 and the piston plate 52, the three Z-shaped handles 3 can rotate at an angle, making it easy to hold the device by hand and also stable to place on a table. Through the sliding connection between the piston plate 52 and the shock absorber 51, the return spring 53 resets the piston plate 52, thus creating a shock absorption buffer between the Z-shaped handle 3 and the shock absorber 51. By setting up a single-beam echo sounder with RTK, multi-beam sonar with IMU, GNSS with electronic charts, and Beidou terminal with tide module, high-precision water depth and topographic mapping, deep-sea 3D imaging and navigation compensation, real-time ship navigation and obstacle avoidance, ocean communication and route optimization, and other functions can be achieved.
