[0002] The existing paddle board propelling technology has several aspects to be improved. The installation process of the traditional paddle board propeller usually involves multiple steps, such as disassembly and installation of screws, which makes the installation process cumbersome and time-consuming, and is not convenient and friendly for users. This complex assembly method requiring manual operation not only increases the user's use burden, but also may cause the propeller to be not firmly installed due to improper operation, affecting the use safety and propelling efficiency.
[0003] In addition, the traditional paddle board propeller mostly adopts a fixed paddle design. This design means that the paddle cannot be automatically folded after use. Even if the paddle stops rotating, it will still remain unfolded, generating a considerable resistance in the water. This not only reduces the sliding speed and endurance of the paddle in the non-propelling state, but also increases the inconvenience of the user in transporting and storing the paddle, such as difficult to compactly store, easy to cause paddle damage, etc.
[0004] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and the utility model is made based on this situation. CONTENT OF THE UTILITY MODEL

[0017] Compared with prior art, the utility model has following advantages:
[0018] 1. The paddle propeller of the utility model can be quickly disassembled.

[0020] 3. The paddle part of the propeller is usually composed of three such freely retractable blades. In actual use, when the driving motor starts, the centrifugal force generated by the rotation will drive the blade holder to turn outward, causing the paddle to automatically unfold, thereby effectively propelling the paddle forward.

The design of the automatically unfolding and folding paddle realizes the balance between propulsion efficiency and low resistance sliding. BRIEF DESCRIPTION OF DRAWINGS

[0027] In order to enable those skilled in the art to better understand the technical scheme of the utility model, the utility model will be further described in detail below in combination with the drawings and specific embodiments.
[0028] The utility model provides a kind of paddle propeller of quick fixing and with automatic folding function, effectively solve the paddle propeller installation cumbersome in prior art, and the problem of large resistance generated by fixed paddle in non-propulsion state.
[0029] Quick disassembly function:
[0030] Reference Figures 1 to 5 As shown in the embodiment, the propeller designs quick fixing assembly and detachable motor connecting structure, to significantly improve installation and maintenance efficiency.
[0031] The paddle propeller mainly includes driving motor 1, rotating seat 2, several paddles 3 and quick fixing assembly. The output shaft of driving motor 1 is connected with rotating seat 2, and several paddles 3 are movably connected on rotating seat 2, for driving paddle forward.
[0032] The design of quick fixing assembly is a highlight of the utility model, which makes the installation and disassembly process of the propeller extremely simple and fast. The assembly includes fixed seat 4 fixed at the rear end of driving motor 1, clamping plate 5 arranged in interval with fixed seat 4, and elastic belt 6 connecting fixed seat 4 and clamping plate 5. Clamping plate 5 is designed in V shape, with forward first V-shaped port 51 matched with backward second V-shaped port 41 at the rear end of fixed seat 4, to form a structure capable of clamping paddle fin.
[0033] In order to protect paddle and provide more stable clamping force, flexible buffer pad 42 is arranged in first V-shaped port 51 and / or second V-shaped port 41.
[0034] Elastic belt 6 passes through perforation 52 on clamping plate 5, and is fixed by locking structure 43 on both sides of fixed seat 4, such as commonly used lock structure. Such locking structure facilitates user to quickly disassemble elastic belt 6. In addition, in order to improve product appearance and protect locking structure, detachable cover 44 can also be connected on fixed seat 4.
[0035] In actual use, user only needs to pull apart clamping plate 5 and elastic belt 6, and then install by sleeving on the fin of paddle. The disassembly process is also simple and fast, which greatly improves user experience compared with the complicated installation steps of traditional paddle propeller.
[0036] In order to further improve user experience and maintenance convenience, detachable connection design is adopted between the front end of driving motor 1 and rotating seat 2, and between the rear end of driving motor 1 and fixed seat 4, preferably adopting fastener (such as screw) connection. Such design enables user to easily disassemble driving motor 1, which is convenient for cleaning sand or other sundries in the motor, for example, after surfing, the motor can be quickly disassembled for cleaning, which effectively prevents sand and other sundries from causing abrasion to the motor, thereby significantly prolonging the service life of paddle propeller and reducing maintenance cost.
[0037] Automatic unfolding and folding of the paddle:
[0038] The paddle board propeller of the utility model has the characteristics of quick disassembly and assembly, and is innovatively designed with paddle structures capable of automatic unfolding and folding, effectively solving the problem of high resistance of traditional fixed paddles in a non-propelling state and improving the sliding efficiency of the paddle board.
[0039] As shown in Figures 1 to 5 each paddle 3 can be automatically unfolded and folded. The paddle 3 is installed on the rotating seat 2 through rotary connection. Specifically, the rotating seat 2 is provided with a plurality of installation grooves 21, and each installation groove 21 is detachably connected with a pin shaft 7. Each paddle 3 is composed of a paddle seat 31 and a paddle blade 32 arranged on the paddle seat 31. The paddle seat 31 is provided with a shaft hole 311 matched with the corresponding pin shaft 7, so that the paddle seat 31 can be flipped forward and backward around the pin shaft 7 in the installation groove 21.
[0040] The front side and the outer side in the radial direction of the installation groove 21 are open, and the paddle seat 31 is designed as a block structure. This design enables the paddle 3 to have the functions of automatic unfolding and folding: when the paddle seat 31 is flipped inward to the limit position in the installation groove 21, the paddle 3 will be folded to the axial direction and closely attached to the rotating seat, thereby minimizing the resistance of the paddle in water and facilitating the transportation and storage of the paddle board; when the paddle seat 31 is flipped outward to the limit position, the paddle 3 will be completely unfolded to the radial direction to provide the maximum propelling force.
[0041] The paddle part of the propeller is usually composed of three such freely collapsible paddle blades. In actual use, when the driving motor 1 starts, the paddle 3 begins to rotate, and the centrifugal force generated by rotation will drive the paddle seat 31 to flip outward, so that the paddle 3 is automatically unfolded, thereby effectively propelling the paddle board forward; when the motor stops rotating, the reverse water flow force generated by the forward movement of the paddle board will push the paddle seat 31 to flip inward, so that the paddle 3 is automatically folded, thereby reducing the resistance of the paddle in water and improving the sliding speed and endurance of the paddle board in a non-propelling state. The design of the automatically unfolded and folded paddle realizes the balance between propelling efficiency and low-resistance sliding.
