[0002] At present, with the improvement of living standards, diving is becoming more and more popular. Underwater activities rely solely on one's own physical strength to move forward with fins, which is not only slow, but also consumes a lot of physical strength and has a limited range of activities. Therefore, underwater thrusters as a diving auxiliary equipment are increasingly respected by diving enthusiasts.

They mainly generate thrust by driving a shaft propeller with a drive motor to assist underwater movement. They may become entangled when encountering foreign objects such as ropes.

[0035] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The terms such as "upper", "lower", "left", "right", and "middle" used in this specification are only for the convenience of description and are not intended to limit the scope of the invention. Changes or adjustments to their relative relationships should be regarded as within the scope of the invention without substantially changing the technical content.

[0037] Example 1

[0038] like Figure 1 to Figure 2 As shown, the embodiment of the present invention provides a wearable reversible shaftless propeller for underwater diving, including a body structure 1, an articulated component 2, a rim propeller 3, a fixed base bracket 4 and a base strap 5. When diving underwater, the rim propeller 3 can be rotated and unfolded in the forward direction or rotated in the opposite direction to reset based on the body structure 1 through the articulated component 2, so that on the basis of being able to complete the boost and cancel the boost function, the possibility of the propeller being entangled can be significantly reduced; at the same time, the fixed base bracket 4 and the base strap 5 are used to allow the rim propeller 3 to be tied and worn on the limbs of the diver, thereby improving practicality. The specific settings are as follows:

[0039] Please refer to Figure 1 to Figure 2 The propeller has a forward direction, a waterproof cabin is provided inside the body structure 1, and batteries and control circuits electrically connected to each other are arranged inside the waterproof cabin. The rim propeller 3 is electrically connected to the batteries and control circuits inside the waterproof cabin, so that the batteries and control circuits serve as the power basis and underwater control basis of the rim propeller 3 respectively.

[0040] The hinged component 2 is fixedly connected to the side of one end of the body structure 1, the rim propeller 3 is a shaftless annular propeller, and a hinged connecting rod 31 is fixedly connected to one side of the rim propeller 3, and the rim propeller 3 is connected to the hinged component 2 through the hinged connecting rod 31, so that the rim propeller 3 can be rotated and expanded based on the forward direction to form a propulsion state or rotated in the opposite direction to form a reset state.

[0041] As a preferred solution of this embodiment, the wearable flippable shaftless propeller for underwater diving also includes a limiting component 21, which is fixedly connected to the hinged component 2, and the limiting component 21 is located on the switching path of the rim propeller 3 from the reset state to the propulsion state, so as to limit the rim propeller 3 from continuing to rotate when the rim propeller 3 rotates to the preset angle of the propulsion state through the limiting component 21, so that the rim propeller 3 can be maintained at the preset angle of the propulsion state.

[0042] In an optional implementation, the limiting member 21 is made of a magnetic material, and the corresponding part of the rim propeller 3 is made of a metal or ferromagnetic material, so as to effectively increase the stability of the rim propeller 3 when it reaches the limiting angle through the magnetic attraction between the rim propeller 3 and the limiting member 21.

[0043] When the propeller is not in operation, the radial plane of the rim propeller 3 is parallel to the plane of the forward direction, i.e., the reset state. When the rim propeller 3 starts to work underwater, the rim propeller 3 is controlled by a button electrically connected to the control circuit to drive its rotor to rotate forward, and the rim propeller 3 automatically enters the propulsion state by using its own thrust. When the rim propeller 3 needs to be reset, the rotor of the rim propeller 3 is reversed by controlling the button, and the reverse thrust is used to make it rotate in the reverse direction to the reset state.

[0044] The above scheme utilizes the rim propeller 3 to replace the shaft propeller to achieve the effect of preventing entanglement and reducing the overall volume of the underwater propeller, and adopts a folding method in which the rim propeller 3 can be rotated, unfolded, and reset to make the propeller more convenient to carry. At the same time, since there is no obstruction in front of the rim propeller 3, a higher propulsion efficiency is achieved.

[0045] As another preferred solution of this embodiment, the rim propeller 3 can adopt the "axial flux" type rim propeller known in the prior art. The so-called "axial flux" rim propeller refers to an annular propeller in which the direction of the magnetic flux generated by the annular stator winding is parallel to the extension direction of the gap between the rotor and the stator. When viewed from the radial direction, the rotor and stator of the "axial flux" rim propeller are coaxially arranged in parallel along the axial direction. The advantage of the "axial flux" rim propeller over the "radial flux" rim propeller is that it is thinner and smaller in size.

[0046] As another preferred solution of this embodiment, the water inlet and the water outlet of the rim thruster 3 are equipped with protective nets to further reduce the risk of entanglement.

[0047] More preferably, the hinge member 2, the limiting member 21 and the outer shell of the body structure 1 are integrally formed to reduce the assembly process, reduce costs and improve overall stability.

[0048] Please continue to refer to Figure 1 to Figure 2 The fixed base bracket 4 is detachably fixed to one side of the body structure 1, and the fixed base bracket 4 is provided with a base strap 5 on the side away from the body structure 1, so that the rim thruster 3 can be tied and worn on the limbs of the diver.

[0049] Preferably, the fixed base bracket 4 has a specific arc-shaped structure to make the fixed base bracket 4 more ergonomic and more comfortable when tied to the diver's limbs.

[0050] Example 2

[0051] In Example 2, the same symbols are given to the same structures as those in Example 1, and the same descriptions are omitted. Example 2 is improved on the basis of Example 1, such as Figure 3 As shown, the fixed base bracket 4 and the body structure 1 are of a split structure, the hinged member 2 is fixedly connected to the fixed base bracket 4, the rim propeller 3 is connected to the hinged member 2 through the hinged connecting rod 31, and the body structure 1 and the rim propeller 3 are connected through an external electrical connection, so that the heavier body structure 1 can be worn on the diver, so that the diver's limbs bear less weight during diving, and the movement is easier, thereby improving the functional practicality of the overall structure.

[0052] Example 3

[0053] In Example 3, the same symbols are given to the same structures as in Examples 1 and 2, and the same descriptions are omitted. Example 3 is improved on the basis of Example 2, such as Figures 4 to 5 As shown, the side of the body structure 1 is also equipped with a waist strap 6 fixedly connected thereto, which is used to be fastened to the waist of a human body through the waist strap 6, so that the heavier body structure 1 can be worn on the waist of a diver to reduce the weight on the limbs.

[0054] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
