Description

Technical Field

[0001] This application belongs to the field of boat steering technology, specifically relating to a base assembly for mounting an electric propulsion unit. Background Technology

[0002] In recent years, with people's growing love and pursuit of outdoor sports, the market for water recreational boats such as kayaks has shown a booming development trend. As a key component for these boats to achieve power output and directional control, the performance of the electric propulsion system directly determines the boat's operating efficiency and handling experience. From the perspective of industry development trends, users' needs for water recreational boats are gradually extending to multiple dimensions such as safety, convenience, and maintainability, which also places higher demands on the connection technology between the electric propulsion system and the hull.

[0003] However, current mainstream electric propeller connection solutions for kayaks generally suffer from technical bottlenecks. Some products use simple buckles or elastic straps for installation. While these solutions offer the advantage of easy installation, in real-world scenarios, such as turbulent water currents, the impact of high-speed travel, and frequent swaying of the boat, the connection structure struggles to provide a continuous and stable clamping force. This can easily cause the propeller to loosen and shift, or even detach from the boat in extreme cases, resulting in equipment damage and potentially endangering the user's safety.

[0004] Another type of electric propeller, assembled through rotating structures such as welding and fixed shaft connections, offers some structural strength, but its non-removable nature exposes significant drawbacks in maintenance. If a mechanical failure or electronic component damage occurs inside the propeller, the user cannot quickly detach it from the hull; maintenance personnel must use specialized tools to disassemble the entire structure, greatly increasing the complexity and time cost of repairs. Furthermore, the non-removable design limits the product's portability, causing considerable inconvenience for users in both long-distance transport and daily storage, failing to meet the modern consumer demand for convenient water sports equipment. Utility Model Content

[0005] The purpose of this application is to provide a base assembly for mounting an electric thruster that is stable to install, easy to disassemble, and convenient to maintain.

[0006] The embodiments of this application can be implemented through the following technical solutions: An electric propulsion mounting base assembly is disclosed. The electric propulsion includes a support rod, and control handles and an underwater thruster respectively disposed at the upper and lower ends of the support rod. The base assembly is rotatably connected to the support rod. The base assembly includes a first base, a second base, and a locking part. The first base and the second base are coaxially disposed with the support rod. The first base is connected to the hull and is lockably connected to the outer periphery of the second base through the locking part. The second base is rotatably connected to the support rod.

[0007] Furthermore, the second base includes a second end face, a surrounding structure, and a protruding structure. The surrounding structure is a cylindrical structure, through which the support rod is disposed, and is rotatably connected to the support rod via a rotating structure. The second end face is located at the top of the second base and connected to the outer periphery of the surrounding structure, and the second end face is limitedly connected to the first base. The protruding structure is located on the outer periphery of the second base and is lockably connected to the locking part.

[0008] Preferably, the second base further includes a reinforcing structure, which is connected to the lower end face of the second end face.

[0009] Furthermore, the reinforcing structure is a plate-like structure, which is vertically connected to the lower end face of the second end face and simultaneously connected to the periphery of the surrounding structure.

[0010] Preferably, the reinforcing structure is provided with reinforcing ribs.

[0011] Preferably, the upper and / or lower end faces of the second end face are provided with reinforcing ribs.

[0012] Preferably, the second base consists of two centrally symmetrical structures, and the two structures are detachably connected.

[0013] Furthermore, the locking part includes a connector, and the first base has a groove structure for accommodating the locking part, and the bottom end of the connector is connected to the groove structure of the first base.

[0014] Furthermore, the locking part also includes a movable member and a receiving member. The movable member and the receiving member are both connected to the top of the connecting member. The receiving member has a locking groove for the protruding structure to slide into and abut against. The movable member is movably connected to the connecting member and can close the locking groove to form a limiting constraint on the protruding structure.

[0015] Furthermore, the first base is provided with a through hole that accommodates the second base and extends along the axis of the support rod, the cross-sectional shape of the through hole matching the outer periphery of the second base.

[0016] The embodiments of this application provide an electric thruster mounting base assembly that has at least the following beneficial effects: This application connects to the hull via a first base, rotates to a support rod via a second base, and connects the first base and the second base via a locking part. While ensuring the connection strength between them, it supports quick disassembly and assembly, providing great convenience for daily maintenance and fault diagnosis. The movable component of this application is connected to the connecting component via a hinge shaft or slide rail, and has two movement modes: rotation around the shaft or horizontal sliding. When the extended structure is embedded in the locking groove of the receiving component, the operator can drive the movable component to close by simple operations such as flicking or pressing. The wedge-shaped locking tongue or latching protrusion at its closed end forms a secondary locking structure with the edge of the groove, which provides all-round limiting constraints on the extended structure, ensuring that the second base and the first base always maintain a rigid connection under complex working conditions such as water flow impact and ship vibration. When disassembly is required, the movable component can be unlocked by reversing the operation, which can quickly separate the second base, greatly improving the equipment maintenance efficiency. This application enhances the structural strength of the second base and reduces the risk of deformation by strengthening the structure and reinforcing ribs, thereby further ensuring the stability of the connection and its ability to resist external impacts.

Detailed Implementation

[0019] The present application will now be further described based on preferred embodiments and with reference to the accompanying drawings.

[0020] The vocabulary used in this specification is for illustrative purposes and is not intended to limit the scope of this application. Unless otherwise expressly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection via an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art will understand the specific meaning of these terms in this application.

[0021] Furthermore, in the description of the embodiments of this application, various components on the drawings have been enlarged or reduced for ease of understanding, but this is not intended to limit the scope of protection of this application.

[0022] This application proposes a base assembly for mounting an electric propeller, aiming to solve the problems of poor connection stability and inconvenient disassembly and maintenance of the electric propeller X to the hull in the prior art. The base assembly is adapted to a hull with mounting holes and achieves a stable connection through a tight fit with the electric propeller X. The electric propeller X includes a control handle, a support rod, and an underwater thruster, wherein the control handle and the underwater thruster are respectively mounted at the upper and lower ends of the support rod, forming an integrated structure for operation and power output. The base assembly is connected to the support rod through a specific connection method, which not only ensures that the electric propeller X is firmly mounted to the hull, but also allows the support rod to rotate circumferentially around its own axis, thereby meeting the user's need for flexible adjustment of the propeller's direction during navigation and improving the handling performance and user experience of water recreational vessels such as kayaks.

[0023] Figure 1 and Figure 2 The overall structural diagrams of the base assembly and the electric thruster X in this application are shown respectively, as well as the overall structural diagram of the base assembly itself. Figure 1 and Figure 2As shown, the base assembly 1 is rotatably connected to the support rod. The base assembly 1 includes a first base 11, a second base 12, and a locking part 13. The first base 11 and the second base 12 are coaxially arranged with the support rod, ensuring the stability and directionality of power transmission. The first base 11 is connected to the hull and can be securely installed by bolt fastening, snap-fit ​​connection, or other methods by adapting to the pre-set mounting holes on the hull. The second base 12 is rotatably connected to the support rod. Through a high-precision bearing or rotating structure, the support rod can rotate freely 360° around its own axis, allowing the user to flexibly adjust the direction of the electric thruster X during navigation. The locking part 13, as a key component connecting the first base 11 and the second base 12, adopts a lockable design and is lockably connected to the outer periphery of the second base 12. While ensuring the connection strength between the two, it supports quick disassembly and assembly, providing great convenience for daily maintenance and fault diagnosis.

[0024] Specifically, Figure 3 This application shows an overall structural diagram of the connection between the first base 11 and the locking part 13, as shown in the figure. Figure 3 As shown, the first base 11 serves as the basic support structure of the base assembly 1. It has a through hole extending longitudinally along the axis of the support rod. The cross-sectional shape of the through hole matches the outer periphery of the second base 12 to form an embedded assembly relationship. The upper surface of the first base 11 also has a groove structure that extends radially to the edge of the through hole to accommodate the locking part 13.

[0025] Furthermore, the bottom end of the locking part 13 is connected to the bottom of the groove structure by a pin or bolt, and part of the structure of the locking part 13 can swing within the groove structure, thereby realizing the locking and unlocking operation of the outer periphery of the second base 12.

[0026] Furthermore, the depth of the groove structure is adapted to the thickness of the locking part 13, ensuring that the top of the locking part 13 is completely submerged in the groove when not in operation, without affecting the lifting degree of the first base 11 and the hull; while in the locked state, the locking part 13 is provided with a locking groove and forms a snap-fit ​​with the outer periphery of the second base 12, achieving a rigid connection between the two through mechanical interference.

[0027] Furthermore, Figure 4 It shows Figure 3 A magnified view of a portion of region A in the middle, as shown below. Figure 4 As shown, the locking part 13 includes a connector 131, the bottom end of which is connected to the groove structure of the first base 11.

[0028] Furthermore, the locking part 13 also includes a movable part and a receiving part 133. Both the movable part and the receiving part 133 are connected to the top of the connecting part. The receiving part 133 has a locking groove for the extension structure 123 of the second base 12 to slide into and abut against. The movable part is movably connected to the connecting part 131 and can close the locking groove to form a limiting constraint on the extension structure 123. The movable component is connected to the connector 131 via a hinge shaft or slide rail, and has two movement modes: rotation around the axis or horizontal sliding. When the protruding structure 123 is inserted into the locking groove of the receiving component 133, the operator can drive the movable component to close by simple operations such as flicking or pressing. The wedge-shaped locking tongue or latching protrusion at its closed end forms a secondary locking structure with the edge of the groove, which provides all-round limiting constraint on the protruding structure 123, ensuring that the second base 12 and the first base 11 always maintain a rigid connection under complex working conditions such as water flow impact and ship vibration. When disassembly is required, the movable component can be unlocked by reversing the operation, which can quickly separate the second base 12, greatly improving the equipment maintenance efficiency.

[0029] In some preferred embodiments of this application, there are multiple locking parts 13 to further ensure the stability of the connection between the first base 11 and the second base 12.

[0030] In some preferred embodiments of this application, the outer periphery of the first base 11 and the cross-section of the through hole that accommodates and mounts the second base 12 are both designed with a non-circular structure to achieve a circumferential limiting function.

[0031] Furthermore, Figure 5 and Figure 6 The overall structural diagrams of the second base 12 in this application are shown at different angles, as follows: Figure 5 and Figure 6 As shown, the second base 12 includes a second end face 121, a surrounding structure 122, and a protruding structure 123. The surrounding structure 122 is a cylindrical structure, and a support rod is inserted through it. Its inner diameter and the outer diameter of the support rod form a precise clearance fit, and it is rotatably connected to the support rod through a rotating structure such as a bearing. The second end face 121 is located at the top of the second base 12 and extends to the outer periphery of the surrounding structure 122 in the shape of an annular plate. The second end face 121 is limited to the first base 11, which effectively resists radial shear force while achieving axial positioning. The protruding structure 123 is located on the outer periphery of the second base 12 and can be locked to the locking part 13 to realize the rapid assembly and separation of the first base 11 and the second base 12.

[0032] In some specific embodiments of this application, for ease of processing and assembly, the second base 12 is composed of two centrally symmetrical structures, and the two structures are detachably connected by means of threaded connection, snap-fit ​​connection or other methods.

[0033] In some specific embodiments of this application, such as Figure 6 As shown, the bottom end of the second end face 121 is provided with a pair of mounting seats for mounting long screws. The mounting seats have through holes through which the long screws pass. The detachable connection of the centrally symmetrical structure is achieved by connecting the long screws and nuts in a spiral manner.

[0034] In some preferred embodiments of this application, the second base 12 further includes a reinforcing structure 124, which is connected to the lower end face of the second end face 121 to improve the support and connection strength of the second base 12.

[0035] In some specific embodiments of this application, the reinforcing structure 124 is a plate-shaped structure that is radially distributed and is vertically connected to the lower end face of the second end face 121, and is also connected to the periphery of the surrounding structure 122, so as to enhance the connection strength between the second end face 121 and the surrounding structure 122 to resist radial torque.

[0036] In some preferred embodiments of this application, the reinforcing structure 124 is provided with reinforcing ribs to further improve the bending and torsional strength of the second base 12.

[0037] In some preferred embodiments of this application, the upper and / or lower end faces of the second end face 121 are provided with reinforcing ribs to further improve the structural rigidity of the second base 12 and reduce the risk of deformation.

[0038] In some preferred embodiments of this application, to further improve the connection stability between the first base 11 and the second base 12, the base assembly further includes a limiting part. The limiting part is connected to the through hole of the first base 11 and limits the second base 12 from the vertical direction. The addition of the limiting part not only effectively resists the axial load generated by the water flow impact, but also improves the coaxiality and connection stability of the first base 11 and the second base 12, while ensuring the smoothness of the support rod during rotation.

[0039] Furthermore, the limiting part includes a first limiting member 141 and a second limiting member. The first limiting member 141 is connected to the inner wall of the through hole of the first base 11 and can abut against the bottom end of the second base 12 to prevent the second base 12 from falling out downward. The second limiting member is detachably connected to the through hole of the first base 11 and can fit against the lower end face of the second end face 121 to restrict the upward displacement of the second base 12.

[0040] The specific embodiments of this application have been described in detail above. For those skilled in the art, several improvements and modifications can be made to this application without departing from the principle of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
