Description

Technical Field

[0001] This application relates to the field of underwater measurement equipment technology, and in particular to a battery fixing structure and an unmanned vessel. Background Technology

[0002] Underwater topographic surveying is a specific type of surveying work in engineering surveying. It primarily measures the horizontal position and elevation of rivers, lakes, reservoirs, harbors, and nearshore points to create underwater topographic maps. In recent years, with the rapid development of water conservancy and the increasing emphasis on water resources, the geographical information of rivers and reservoirs has received increasing attention. Among these, acquiring topographic data on rivers and reservoirs has become a focal point.

[0003] Underwater topographic surveying primarily utilizes acoustic and optical equipment for data acquisition. With technological advancements, unmanned surface vessels (USVs) equipped with surveying equipment are increasingly replacing manual surveying. Current technologies typically utilize USVs carrying equipment such as ADCPs and dual-frequency depth sounders to measure river flow velocity, discharge, and depth. To obtain accurate measurement data, stringent requirements are placed on the protection of the vessel hull.

[0004] Common battery mounting methods for unmanned surface vessels (USVs) typically involve straps or custom-designed snap-fit ​​mechanisms. However, due to the limited operating space and heavy batteries of USVs, this presents significant inconvenience during actual operation. The battery is the energy output component of the USV, used frequently, and requires high levels of reliability and usability. Insufficient ease of operation will affect operational efficiency, result in a poor user experience, significantly reduce market acceptance, and ultimately cause the product to lose its market competitiveness. Utility Model Content

[0005] This application aims to solve one of the aforementioned technical problems in the prior art. Therefore, embodiments of this application provide a battery fixing structure.

[0006] This application also provides an unmanned surface vessel.

[0007] According to an embodiment of the first aspect of this application, a battery fixing structure is provided, including a hull, wherein an installation compartment for installing a battery is provided inside the hull; A battery is placed in the mounting compartment, and at least one set of opposite sides of the battery have gaps between them and the mounting compartment. At least two sets of connecting components are respectively disposed in the gaps on both sides of the battery. Each connecting component includes a first connecting member and a second connecting member. One end of the first connecting member is rotatably disposed in the mounting compartment, and the second connecting member is fixed to the side or top surface of the battery. The other end of the first connecting member can be rotated to engage with the second connecting member. The end of the first connecting member that engages with the second connecting member is provided with a pre-tightening structure. The pre-tightening structure can provide a pre-tightening force, which causes the first connecting member and the second connecting member to cooperate to press the battery toward the bottom of the mounting compartment.

[0008] The aforementioned battery fixing structure has at least the following beneficial effects: Before placing the battery in the mounting compartment of the hull, the first connecting member is flipped towards the compartment wall to prevent its placement from affecting battery installation. After placing the battery in the mounting compartment, the first connecting member is flipped and adjusted so that its end engages with the second connecting member on the battery, completing the initial positioning of the battery. Then, the tension of the first connecting member is adjusted by the pre-tightening structure. The pre-tightening force provided by the pre-tightening structure causes the first and second connecting members to cooperate in pressing the battery against the bottom of the mounting compartment, thus completing the positioning and fixing of the battery. The design of the connecting components simplifies the battery locking and fixing method, making the entire installation and fixing process simple and fast. The pre-tightening structure also firmly presses and fixes the battery to the mounting compartment, preventing swaying during hull navigation from affecting the hull's direction.

[0009] According to the battery fixing structure described in the first aspect of this application, the first connecting member includes a first locking body, and the pre-tightening structure includes a rotatable pulling member. The first locking body is rotatably disposed on the pulling member. When the rotation center of the first locking body is between the rotation center of the pulling member and the second connecting member, the first locking body can be engaged with the second connecting member. When the rotation center of the pulling member is between the rotation center of the first locking body and the second connecting member, the pre-tightening force provided by the pulling member causes the first locking body to have a tendency to move away from the first connecting member.

[0010] According to the battery fixing structure described in the first aspect of this application, the pre-tightening structure further includes a fixing seat, the fixing seat being detachably connected to the first connecting member, and the pulling member being rotatably disposed at the end of the fixing seat. The side of the fixing seat that contacts the first connecting member is designated as the first mounting surface. When the pulling member rotates to fit against the fixing seat, the vertical distance between the rotation center of the pulling member and the first mounting surface is greater than the vertical distance between the first lock body and the first mounting surface.

[0011] According to the battery fixing structure described in the first aspect of this application, a first connecting ear is provided on both sides of the end of the fixing base, and a second connecting ear is provided on both sides of the pulling member, wherein the second connecting ear is rotatably connected to the first connecting ear.

[0012] According to the battery fixing structure described in the first aspect of this application, the second connecting member is disposed on the top surface of the battery, the first connecting member includes a first connecting piece, one end of the first connecting piece is rotatably disposed in the mounting chamber, the pre-tightening structure is fixed to the other end of the first connecting piece, and when the first lock body can be fastened to the second connecting member, a portion of the first connecting piece is in contact with the side and / or top surface of the battery.

[0013] According to the battery fixing structure described in the first aspect of this application, the first connector is provided with a bending portion, and the inner side of the bending portion can fit against the side and / or top surface of the battery.

[0014] According to the battery fixing structure described in the first aspect of this application, the first connector is rotatably mounted to the mounting compartment via a hinge structure. The hinge structure includes a first hinge and a second hinge. The first hinge is detachably connected to the mounting compartment, and the second hinge is detachably connected to the first connector. The included angle between the first hinge and the second hinge can vary from 0 to 90°, so that the first connector can rotate to be perpendicular to the bottom of the mounting compartment.

[0015] According to the battery fixing structure described in the first aspect of this application, a first limiting surface and a second limiting surface are respectively provided on the two adjacent sides of the second hinge member. The first limiting surface and the second limiting surface are connected by an arc surface. The first limiting surface, the second limiting surface and the arc surface are all equidistant from the rotation center of the second hinge member. Both the first limiting surface and the second limiting surface can rotate to fit against the first hinge member.

[0016] According to the battery fixing structure described in the first aspect of this application, the second connecting member has a locking hook, and the first locking body is a locking ring that can engage with the locking hook; or, the second connecting member has a locking hole, and the first locking body is a locking hook that can engage with the locking hole.

[0025] Unmanned surface vessel (USV) surveying primarily relies on mounted surveying equipment for operations. This equipment mainly comprises the hull, external equipment, central control system, and mounting screws. Typically, the battery is installed inside the hull. Furthermore, to ensure the overall stability and reliability of the hull, the battery pack must be securely fixed to guarantee reliable operation in water. The example shown in the illustration depicts the battery mounted at the front of the hull bottom (e.g.,...). Figure 1 (As shown).

[0026] Before assembly is completed, all internal cables of the ship must be connected to the corresponding external interfaces of the central control equipment.

[0027] There are several ways to secure batteries for unmanned surface vessels (USVs). The first, and most common method, is using Velcro straps. This method is inexpensive, cost-effective, and provides adequate stability. However, it's inconvenient for battery removal because the straps are soft and difficult to shape. Furthermore, the batteries are heavy; a typical 1.2-meter boat battery weighs around 7.5 kg. The operator needs to use one hand to place the battery within the confined space of the boat. Also, the straps often become molded within the battery compartment, frequently pressing against them during installation, requiring multiple attempts to secure the battery and significantly impacting efficiency. Another method involves designing a battery securing mechanism. Mechanical mechanisms offer better shaping and control compared to straps. However, these are often custom-made parts with different structural shapes. In today's competitive market, custom parts are a significant cost factor, and battery removal requires specific shapes and other constraints, making this method less versatile and not the optimal solution.

[0028] like Figures 1 to 6 As shown in the figure, this application provides an unmanned vessel, which includes a battery fixing structure.

[0029] Specifically, the unmanned vessel includes a hull 100, a central control unit 120 at the front end of the hull 100, a propulsion unit 110 at the bottom and stern of the hull 100, an installation compartment 101 and a cover 130 at the rear top of the hull 100, and a battery 140 placed in the installation compartment 101.

[0030] To effectively solve the problem of fixing the battery 140, this application provides an optimized battery fixing structure, which includes a hull 100, a battery 140, and at least two sets of connecting components 200.

[0031] The hull 100 is provided with an installation compartment 101 for installing a battery 140. The battery 140 is placed in the installation compartment 101. At least one pair of opposite sides of the battery 140 have gaps with the installation compartment 101. In this embodiment, the battery 140 and the same side of the left and right sides of the hull 100 have gaps with the installation compartment 101.

[0032] There are two sets of connecting components 200. The two sets of connecting components 200 are stacked on both sides of the battery 140 and located in the gap. The battery 140 can be quickly installed and removed through the connecting components 200.

[0033] The connecting assembly 200 includes a first connecting member and a second connecting member 141. One end of the first connecting member is rotatably disposed in the mounting compartment 101, and the second connecting member 141 is fixed to the side or top surface of the battery 140. The other end of the first connecting member can be rotated to engage with the second connecting member 141. The end of the first connecting member that engages with the second connecting member 141 is provided with a pre-tightening structure. The pre-tightening structure can provide a pre-tightening force, which causes the first connecting member and the second connecting member 141 to cooperate to press the battery 140 toward the bottom of the mounting compartment 101.

[0034] When unmanned surface vessel (USV) testing is required, open hatch 130, as follows: Figure 3 As shown, before placing the battery 140 in the mounting compartment 101, the first connecting member is flipped towards the wall of the mounting compartment 101 to avoid the placement of the first connecting member affecting the installation of the battery 140, thus providing more space for the battery 140. This advantage is that it provides a larger and more obvious operating space than setting a fixed structural component to fix the battery 140, because by simply adding a protruding component inside the mounting compartment 101, the actual usable space is greatly reduced.

[0035] After placing the battery 140 into the mounting compartment 101 of the hull 100, as follows Figure 5As shown, the first connecting member is flipped and adjusted so that its end moves to engage with the second connecting member 141 on the battery 140, thus initially positioning the battery 140. Then, the tension of the first connecting member is adjusted by the pre-tightening structure. The pre-tightening force provided by the pre-tightening structure causes the first connecting member and the second connecting member 141 to cooperate, pressing the battery 140 towards the bottom of the mounting compartment 101, thereby completing the positioning and fixing of the battery 140. The connection assembly 200 simplifies the locking and fixing method of the battery 140, making the entire installation and fixing process simple and quick. The pre-tightening structure also firmly presses and fixes the battery 140 to the mounting compartment 101, preventing swaying of the hull 100 during navigation and affecting its direction of travel.

[0036] In some other embodiments, such as Figures 3 to 7 As shown, the first connecting member includes a first locking body 260, and the pre-tightening structure includes a rotatable pulling member 250. The first locking body 260 is rotatably disposed on the pulling member 250. When the rotation center of the first locking body 260 is between the rotation center of the pulling member 250 and the second connecting member 141, the first locking body 260 can be engaged with the second connecting member 141. When the rotation center of the pulling member 250 is between the rotation center of the first locking body 260 and the second connecting member 141, the pre-tightening force provided by the pulling member 250 causes the first locking body 260 to tend to move away from the first connecting member, so that the first connecting member and the second connecting member 141 cooperate to pull and press the battery 140.

[0037] Among them, such as Figure 4 and Figure 6 As shown, the rotation center of the pulling member 250 is set as the first rotation center 251, and the rotation center of the first lock body 260 is set as the second rotation center 361. When the first lock body 260 and the second connecting member 141 are in the latching state, the pulling member 250 is flipped so that the second rotation center 261 is gradually adjusted from being between the first rotation center 251 and the second connecting member 141 to being between the second rotation center 261 and the second connecting member 141. During this process, the preload provided by the pulling member 250 gradually increases.

[0038] The pre-tightening structure of this application provides pre-tightening force while maintaining a constant pre-tightening force acting on the first lock body 260.

[0039] In some specific embodiments, the pre-tightening structure further includes a fixed seat 240, which is detachably connected to the first connecting member. The pulling member 250 is rotatably disposed at the end of the fixed seat 240. The side of the fixed seat 240 that contacts the first connecting member is designated as the first mounting surface. When the pulling member 250 rotates to fit against the fixed seat 240, the vertical distance between the rotation center of the pulling member 250 and the first mounting surface is greater than the vertical distance between the first lock body 260 and the first mounting surface.

[0040] That is, when the pulling member 250 rotates to fit with the fixed seat 240, the direction of the pre-tightening force is to make the pulling member 250 continuously pull towards the fixed seat 240, so that the pulling member 250 will not reverse without external force intervention, thereby achieving self-locking and maintaining a constant pre-tightening force acting on the first lock body 260.

[0041] The fixing base 240 is connected to the first connecting component by bolts, and it is easy to disassemble and assemble when the fixing base 240 is damaged.

[0042] In some embodiments, such as Figure 7 As shown, the fixed base 240 has a first connecting ear on both sides of its end, and the pulling member 250 has a second connecting ear on both sides. The second connecting ear is rotatably connected to the first connecting ear, so that the pulling member 250 can rotate relative to the fixed base 240.

[0043] In this embodiment of the application, in order to reduce costs, both the fixing base 240 and the pulling member 250 are made of sheet metal, and the connecting ears are formed by bending. Then, the first connecting ear and the second connecting ear are rotated together with the locking pin.

[0044] In the embodiment shown in this application, the second connecting member 141 is disposed on the top surface of the battery 140, and the first connecting member includes a first connector 230. One end of the first connector 230 is rotatably disposed in the mounting chamber 101, and the pre-tightening structure is fixed to the other end of the first connector 230. When the first lock body 260 can be fastened to the second connecting member 141, a portion of the first connector 230 is in contact with the side and / or top surface of the battery 140, so that the pre-tightening force transmitted to the battery 140 through the first connector 230 is more uniform, avoiding excessive pre-tightening force from damaging the battery 140 or causing the battery 140 to malfunction.

[0045] Specifically, a portion of the first connector 230 can be attached to the side of the battery 140, and a portion of the first connector 230 can also be attached to the top surface of the battery 140. The first connector 230 can also be attached to both the top and side surfaces of the battery 140.

[0046] In the embodiment shown in this application, a portion of the first connector 230 is attached to the top and side surfaces of the battery 140.

[0047] In some specific embodiments, such as Figure 7 As shown, the first connector 230 is provided with a bent portion, the inner side of which can fit against the side and / or top surface of the battery 140.

[0048] The bent portion can fit against the side of the battery 140, and it can also fit against the top surface of the battery 140. The bent portion can also fit against both the top and side surfaces of the battery 140.

[0049] In the embodiment shown in this application, a portion of the bent portion is in contact with the top and side surfaces of the battery 140.

[0050] In this embodiment, the first connector 230 can be made of sheet metal, and the sheet metal is bent to form a bent portion, effectively reducing manufacturing costs.

[0051] In some embodiments, the first connector 230 is rotatably mounted to the mounting compartment 101 via a hinge structure. The hinge structure includes a first hinge 210 and a second hinge 220. The first hinge 210 is detachably connected to the mounting compartment 101, and the second hinge 220 is detachably connected to the first connector 230. The included angle between the first hinge 210 and the second hinge 220 can vary from 0 to 90°, so that the first connector 230 can rotate to be perpendicular to the bottom of the mounting compartment 101. At the same time, the first connector 230 can also be flipped to be parallel to the bottom of the mounting compartment 101 to facilitate the placement of the battery 140.

[0052] The first hinge 210 is connected to the bottom of the installation chamber 101 by bolts, and the second hinge 220 is connected to the first connector 230 by bolts. When a component is damaged, disassembly and assembly are more convenient.

[0053] In some specific embodiments, such as Figures 3 to 7 As shown, the second hinge member 220 has a first limiting surface 222 and a second limiting surface 223 respectively on its two adjacent sides. The first limiting surface 222 and the second limiting surface 223 are connected by an arc surface 221. The first limiting surface 222, the second limiting surface 223 and the arc surface 221 are all equidistant from the rotation center of the second hinge member 220. Both the first limiting surface 222 and the second limiting surface 223 can rotate to fit against the first hinge member 210.

[0054] The rotation range of the second hinge 220 is limited by the first limiting surface 222 and the second limiting surface 223. When the arc surface 221 contacts the first hinge 210, the second hinge 220 can rotate freely to the left and right.

[0055] In the embodiments shown in this application, the second connecting member 141 has a locking hook, and the first locking body 260 is a locking ring that can engage with the locking hook, making the engagement more convenient.

[0056] In some other embodiments, the second connecting member 141 has a keyhole, and the first lock body 260 is a lock hook that can be engaged with the keyhole.

[0057] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
