Description

A wearable underwater waist booster device Technical Field

[0001] The present invention relates to the technical field of underwater propulsion, in particular to a wearable underwater waist propulsion device. Background Art

[0002] Currently, most underwater boosters or boosting devices on the market use a wearable fixing device or a waist fixing ring as a wearing basis, and then the thruster, power supply, etc. are installed and hung on the wearable fixing device or the waist fixing ring.

[0003] For example, the Chinese patent application number CN217100428U, titled "An Underwater Propulsion Device," primarily comprises a wearable fixture, a power source secured to the rear of the wearable fixture, and thrusters secured to both sides of the wearable fixture. One side of the power source is connected to a control handle via a waterproof cable, while the other side of the power source is connected to the thrusters via waterproof cables. This underwater propulsion device, with the power source and thrusters separately located outside the wearable fixture, is relatively bulky and inconvenient to wear and use.

[0004] For example, the announcement number CN205469727U, titled "A Portable Belt-Type Propeller for Underwater Snorkeling," primarily comprises a belt worn around the waist, a buoyancy chamber and two battery packs secured to the rear of the belt, propellers secured to the front of each side of the belt, and a controller and display at the front of the belt. This portable belt-type propeller for underwater snorkeling is a lightweight, closed-loop belt. The battery packs and propellers secured to the outside of the belt can cause tension on the belt, causing discomfort to the wearer.

[0005] The above two methods of fixing the propeller and power supply on the outside of a wearable fixing device or a waist fixing ring / belt are both not conducive to the overall coordination and consistency of the body when moving forward. The external propeller is exposed to the outside, which increases the underwater forward resistance and affects the propulsion effect. Summary of the Invention

[0006] The invention provides a wearable underwater waist-boosting device which is quick and convenient to wear, has good sealing performance, good flexibility and low use cost.

[0007] In order to achieve the above objectives, the following technical solutions are adopted.

[0008] A wearable underwater waist-boosting device comprises a power source, a propeller and a belt, wherein there are two propellers, and a rotatable connector is provided between each propeller and the power source, wherein the power source comprises a battery compartment and a battery assembly arranged in the battery compartment, and the battery assembly is detachably connected to the battery compartment; the two propellers are relatively distributed on both sides of the battery compartment, and are movably connected to the left and right sides of the battery compartment respectively through a rotatable connector, and the inner sides of the outer ends of the two propellers are provided with a belt groove, and the belt groove and the propellers together form a fixed ring; the rotatable connector is provided with a telescopic sealing sleeve, and two sealing surfaces are provided at both ends of the telescopic sealing sleeve, and the two sealing surfaces of the telescopic sealing sleeve located at one end of the propeller are respectively sealed with the rotatable connector and the propeller, and the two sealing surfaces of the telescopic sealing sleeve located at one end of the power source are respectively sealed with the rotatable connector and the battery compartment; the power source, the rotatable connector and the propellers arranged in sequence on both sides form a semi-annular body, and the semi-annular body is adapted to the waist of the human body.

[0009] In the above technical solution, the power supply is placed in the center, and the two sides of the power supply are connected to the propeller through rotatable connecting parts respectively. Finally, two adjustable belts are respectively passed through the belt grooves on the propeller to connect, so that the power supply, propeller and belt together form an annular main body, and the propeller has a certain angle of rotation space relative to the power supply. With this technical solution, the propulsion device is worn on the human waist, and the propeller and power supply are also part of the annular main body. It is not only quick and convenient to wear, but also effectively solves the problem of large underwater resistance caused by the propeller and power supply being externally mounted on the waist propulsion device or the outside of the belt in the prior art, effectively reducing the resistance of water. The entire propulsion device fits the human waist and is installed with better stability and more flexible use. Among them, the power supply is mainly composed of a battery compartment and a battery assembly, and the battery assembly is detachably connected to the battery compartment. When the battery is low on power or damaged, there is no need to replace the entire power supply. Only the battery assembly in the battery compartment needs to be replaced, which avoids the problem of disassembling the entire power supply due to battery problems. It not only effectively saves costs but also greatly facilitates operation; the power supply is placed in the center, and the two sides are connected to the propeller through rotatable connectors. The rotatable connector is set to be detachably connected to the battery compartment and the propeller respectively. At the same time, a telescopic sealing sleeve is provided on the rotatable connector, and one end of the telescopic sealing sleeve is connected to the rotatable connector The first end of the propeller and the battery compartment form a double-sealed connection structure, and the other end forms a double-sealed connection structure with the rotatable connector and the battery compartment. First, it is convenient for installation and provides strength support for the battery compartment and the propeller. Second, it can be used to connect the propeller and the battery compartment so that the propeller can rotate relative to the battery compartment, making the semi-circular main body more flexible in adapting to the human waist. Third, it effectively solves the sealing problem of the power supply, the propeller and the rotatable connector, thereby ensuring the sealing performance of the waist propulsion device; the belt groove on the outer end of the propeller, together with the propeller, constitutes a fixed ring for the belt to pass through.

[0010] Furthermore, the belt is a split structure, including a first belt and a second belt made of soft material, the first belt and the second belt are both adjustable belts, and the first belt and the second belt are respectively used to pass through the fixing rings on the two propellers to form a detachable connection with the propellers.

[0011] In the above technical solution, the belt is a split structure design consisting of a first belt and a second belt mainly made of soft material. After the first belt and the second belt pass through the fixing rings at the outer ends of the thrusters on both sides, the two ends are detachably connected respectively. Compared with the existing fixed clip-in mechanical belt, it is more flexible to operate and has a wider range of uses, and there is no problem that the mechanical belt is prone to corrosion and has difficulty in connection.

[0012] Furthermore, the propeller includes a propeller shell and a booster structure, the propeller shell includes an upper shell and a lower shell, and the upper and lower parts of the booster structure are respectively snap-connected to the upper shell and the lower shell.

[0013] In the above technical solution, the thruster includes a thruster housing. The setting of the thruster housing is used to place the thruster booster structure inside the thruster housing, avoiding the problem of the thruster being exposed to the outside and increasing the underwater forward resistance in the prior art, effectively reducing the resistance of the thruster during the propulsion process, and improving the propulsion effect of the thruster; the thruster housing adopts a split structure consisting of an upper shell and a lower shell, and the upper and lower parts of the booster structure are respectively connected to the upper shell and the lower shell of the thruster housing by snap-fitting, which facilitates the installation of the booster structure. During installation, one end of the booster structure can be snap-fitted and installed with the upper shell or the lower shell first, and then the other end can be installed. The installation is convenient and quick.

[0014] Furthermore, the booster structure includes a duct and a propeller located in the duct, a gap of less than 1 mm is left between the outer edge of the propeller and the inner surface of the duct, a motor is installed in the duct, and the propeller is fixed on the output shaft of the motor.

[0015] In the above technical solution, the propeller is driven to rotate by an electric motor, and the gap between the propeller and the inner surface of the duct is designed to be less than 1 mm. The smaller the gap, the more powerful the thrust of the booster structure, thereby improving the rotation efficiency of the blades.

[0016] Furthermore, the inner surface of the duct is an arc-shaped surface, and the duct diameter at the portion of the duct corresponding to the propeller is smaller than the duct diameter at the inlet end and the outlet end of the duct.

[0017] In the above technical solution, the inner surface of the duct adopts an arc-shaped design with a large diameter at the inlet and outlet ends and a small diameter in the middle. After water enters the blade, it flows into the outlet end through the highest part of the arc, effectively improving the water flow speed and efficiency, thereby improving the propulsion efficiency of the propeller.

[0018] Furthermore, the propeller is composed of a propeller cap and three blades evenly distributed on the outer periphery of the propeller cap. The blades are spirally arranged on the outer circumference of the propeller cap, and the cross section of the blades is a wing shape that is thick in the middle and thin on both sides.

[0019] In the above technical solution, the blade adopts a wing-shaped structure that is thick in the middle and thin on both sides. Compared with the flat-plate structure blade in the prior art, the wing-shaped structure blade has greater blade power, thereby making the propulsion effect of the entire propeller better.

[0020] Furthermore, the water inlet edge and the water outlet edge of the blade are both arc-shaped edges, and the arc curvature of the water outlet edge is greater than the arc curvature of the water inlet edge.

[0021] In the above technical solution, the design of the curved water inlet and outlet edges is more conducive to water inlet and outlet; the structural design in which the curved curvature of the water outlet edge is greater than the curved curvature of the water inlet edge makes the contact area between the water inlet edge of the blade and the water larger. When the motor drives the blade to rotate, the water intake of the blade is greater than the water discharge, which increases the rotational power of the blade, thereby effectively improving the propulsion effect of the propeller.

[0022] Furthermore, the top and bottom ends of the booster structure are detachably connected with a water inlet shield and a water outlet shield, respectively, and the water inlet shield and the water outlet shield are respectively rotatably snap-connected to the inlet and outlet ends of the duct in the booster structure.

[0023] In the above technical solution, the top and bottom ends of the booster structure are detachably connected with a water inlet shield and a water outlet shield, which can effectively prevent debris from entering the duct when the propeller is operating underwater, thereby ensuring the propulsion effect of the propeller; the water inlet shield and the water outlet shield are detachably connected to the inlet and outlet ends of the duct in the booster structure respectively in a rotating snap-on manner, which facilitates the installation and replacement of the booster structure, and effectively avoids the problem that the motor, propeller and other components in the duct cannot be replaced due to the water inlet shield and the water outlet shield being set as a fixed and non-detachable structure with the booster structure. It is not only easy to operate, but also greatly reduces the cost of use.

[0024] Furthermore, the rotatable connecting member includes a propeller connecting member and a battery compartment connecting member, and the propeller connecting member and the battery compartment connecting member are rotationally connected through a rotating shaft. The outer end of the propeller connecting member is plug-in and detachably connected to the propeller housing on the propeller, and the outer end of the battery compartment connecting member is plug-in and detachably connected to the battery compartment.

[0025] In the above technical solution, the thruster connector and the battery compartment connector are rotatably connected, so that the thrusters on both sides of the power supply can be rotated and adjusted relative to the power supply. Compared with the traditional method of using a retractable tube to connect and adjust the thruster and battery compartment, it is not only easy to operate and has a wide range of applications and is suitable for people of different physiques, but also the rotatable connection adjustment is more stable; the thruster connector is plug-in and detachably connected to the thruster housing, and the outer end of the battery compartment connector is plug-in and detachably connected to the battery compartment, which is convenient for installation and replacement, more flexible, and effectively reduces the cost of use.

[0026] Furthermore, a telescopic sealing sleeve is provided at the connection between the propeller connector and the battery compartment connector, and two ends of the telescopic sealing sleeve are respectively sealed with the propeller housing and the battery compartment.

[0027] In the above technical solution, the telescopic sealing sleeve is provided to protect the propeller connector and the battery compartment connector, which can ensure the flexibility of the propeller relative to the power supply. At the same time, it forms a sealed connection between the power supply and the propeller, ensuring the waterproof effect of the propeller's power supply.

[0028] Furthermore, the battery compartment includes a battery compartment body and a battery compartment base, a battery compartment partition is provided in the battery compartment body, the battery compartment partition divides the battery compartment body into an upper battery body and a lower battery compartment body, the upper battery compartment body is a battery assembly mounting groove, the lower battery compartment body is a sealed compartment mounting groove, the battery assembly mounting groove is used to install a battery assembly that is detachably connected to the battery assembly mounting groove, a sealed compartment structure is placed in the sealed compartment mounting groove, and after the sealed compartment structure is placed in the sealed compartment mounting groove, the battery compartment base is covered on the bottom of the battery compartment body to fix the sealed compartment structure in the battery compartment body.

[0029] In the above technical solution, the battery assembly mounting groove on the upper part of the battery compartment body is provided for detachably installing the battery assembly in the battery assembly mounting groove, and the sealing compartment mounting groove on the lower part of the battery compartment body is provided for installing the sealing compartment structure in the sealing compartment mounting groove. The battery compartment body is divided into two parts, upper and lower, so that the battery assembly and the sealing compartment structure are respectively installed in the upper and lower parts of the battery compartment body. This structure is not only reasonably provided, making the overall structure of the power supply compact and occupying a small space, but also adds a sealing compartment structure to ensure the sealing performance of the power supply, thereby effectively ensuring the service life of the power supply and reducing the cost of use.

[0030] Furthermore, the sealed chamber structure includes a sealed chamber upper cover and a sealed chamber bottom cover, a PCBA control board is provided between the sealed chamber upper cover and the sealed chamber bottom cover, the PCBA control board is provided with a battery female socket, multiple wiring female sockets and a low-power vibration motor, an upwardly protruding sleeve is provided at the top center of the sealed chamber upper cover, and the sealed chamber upper cover is also provided with multiple wiring male plugs that extend into the sealed chamber upper cover and are connected to the wiring female sockets in a pin-plug manner. The battery female socket, wiring female socket, wiring male plug and sleeve are all provided with more than one sealing groove, and the sealed chamber upper cover is also provided with an end sealing groove at a position corresponding to the wiring male plug, and sealing rings are provided in the sealing groove and the end sealing groove.

[0031] In the above technical scheme, the setting of sealing grooves on the wiring male plug and the wiring female socket enables the connection between the wiring male plug, the wiring female socket and the sealing chamber cover to form a multi-pass sealing structure; the setting of the end sealing groove on the sealing chamber cover located outside the outer circumference of the wiring male plug enables a sealed connection to be formed between the sealing chamber cover and the connector sealing cover located on the wiring male plug, thereby ensuring the sealing performance and effect of the wiring connection; an upwardly protruding sleeve is provided at the top center position of the sealing chamber cover for being socketed with the battery assembly, and the setting of the sealing groove outside the sleeve enables a sealing structure to be formed at the connection between the sleeve and the battery assembly; the setting of the battery female socket at the position corresponding to the sleeve on the PCBA control board, and the setting of the sealing groove on the battery female socket, enable a sealed connection to be formed with the sleeve when the battery female socket is inserted into the sleeve; this technical scheme performs sealing connections from the outer circumference of the wiring plug and the top of the wiring plug respectively, and at the same time, the battery power supply connection is connected by a double sealing connection inside and outside the sleeve, thereby better realizing the sealing performance of the sealing chamber structure and ensuring its sealing effect.

[0032] Compared with the prior art, the wearable underwater waist booster device of the present invention has the following beneficial effects:

[0033] First, it is quick and convenient to wear, and has good flexibility. The power supply is placed in the center, and the two sides of the power supply are connected to the propellers through rotatable connectors. Finally, two adjustable belts are respectively connected through the belt grooves on the propellers, so that the power supply, propeller and belts together form a ring-shaped main body, and the propeller has a certain angle of rotational activity space relative to the power supply. With this technical solution, the propulsion device is worn on the waist of the human body, and the propeller and power supply are also part of the ring-shaped main body.

When the battery is low or damaged, there is no need to replace the entire power supply. Only the battery assembly in the battery compartment needs to be replaced. This avoids the problem of disassembling the entire power supply due to battery problems, which not only effectively saves costs but also greatly facilitates operation.

[0035] Third, it has a wide range of uses. The belt groove at the outer end of the propeller forms a fixed ring together with the propeller for the belt to pass through. In this solution, the belt is a split structure design consisting of a first belt and a second belt mainly made of soft material. After the first belt and the second belt pass through the fixing rings at the outer ends of the propellers on both sides, the two ends are detachably connected respectively.

[0052] The wearable underwater waist booster device of the present invention will be described in further detail below with reference to specific embodiments and accompanying drawings.

[0053] 1 to 4 and 12, a non-limiting embodiment of the present invention is a wearable underwater waist propulsion device, comprising a power supply 100, a propeller 300 and a waist belt 400, wherein the propellers 300 are two, and a rotatable connector 200 is provided between each propeller 300 and the power supply 100, wherein the power supply 100 comprises a battery compartment 110 and a battery assembly 120 disposed in the battery compartment 110, and the battery assembly 120 is detachably connected to the battery compartment 110; the propellers 300 are two, and the two propellers 300 are relatively distributed on both sides of the battery compartment 110, and are respectively connected to the battery compartment 110 through the rotatable connector 200. 0 is movably connected on both sides, and a belt groove 3121 is provided on the inner side of the outer end of each propeller 300. The belt groove 3121 and the propeller 300 together form a fixed ring to fix the belt 400; the rotatable connector 200 is provided with a telescopic sealing sleeve 230, and both ends of the telescopic sealing sleeve 230 are provided with two sealing surfaces. The two sealing surfaces of the telescopic sealing sleeve 230 located at one end of the propeller 300 are respectively sealed with the rotatable connector 200 and the propeller 300, and the two sealing surfaces of the telescopic sealing sleeve 230 located at one end of the power supply 100 are respectively sealed with the rotatable connector 200 and the battery compartment 110. In this embodiment, the power supply 100 is placed in the center, and the two sides of the power supply 100 are connected to the propeller 300 through the rotatable connecting piece 200, and finally two adjustable belts are respectively connected through the belt groove 3121 on the propeller 300, so that the power supply 100, the propeller 300 and the belt 400 together form an annular body, and the propeller 300 can have a certain angle of rotation space relative to the power supply 100. With this technical solution, the propulsion device is worn on the waist of the human body, and the propeller 300 and the power supply 100 are also part of the annular body. It is not only quick and convenient to wear, but also effectively solves the problem of the propeller in the prior art. The problem of large underwater resistance caused by the external attachment of the waist push device 300 and the power supply 100 to the outside of the waist push device or the waist belt 400 is solved, and the water resistance is effectively reduced. The entire propulsion device fits the human waist and is installed with better stability and more flexible use. In this embodiment, the propulsion device also includes a switch button 500 and a gear button 600. The switch button 500 and the gear button 600 are respectively arranged on the two propellers 300 located on both sides of the power supply 100. The switch button 500 and the gear button 600 are respectively arranged on the two propellers 300, which effectively avoids the problem of setting multiple buttons together in the prior art, which may cause accidental pressing or misoperation.Among them, the power supply 100 is mainly composed of a battery compartment 110 and a battery assembly 120, and the battery assembly 120 is detachably connected to the battery compartment 110. When the battery is low on power or the battery is damaged, there is no need to replace the entire power supply 100. Only the battery assembly 120 in the battery compartment 110 needs to be replaced, which avoids the problem of disassembling the entire power supply 100 due to battery problems, not only effectively saving costs but also greatly facilitating operation; the power supply 100 is placed in the center, and the two sides are connected to the propeller 300 through a rotatable connector 200. The rotatable connector 200 is set to be detachably connected to the battery compartment 110 and the propeller 300 respectively. At the same time, a telescopic sealing sleeve 230 is provided on the rotatable connector 200. One end of the telescopic sealing sleeve 230 forms a double-sealed connection with the rotatable connector 200 and the propeller 300, and the other end forms a double-sealed connection with the rotatable connector 200 and the battery compartment 110.

First, it is easy to install and provides strength support for the battery compartment 110 and the propeller 300. Second, it can be used to connect the propeller 300 and the battery compartment 110, so that the propeller 300 can rotate relative to the battery compartment 110, making the semi-circular body more flexible in adapting to the human waist. Third, the silicone sealing effect is good. Two sealing surfaces are respectively set at both ends of the silicone sealing sleeve, which can effectively solve the sealing problem of the power supply 100 and the propeller 300 and the rotatable connecting member 200, ensure the sealing effect, and thus ensure the sealing performance of the waist propulsion device; the belt groove 3121 at the outer end of the propeller 300 is set, and together with the propeller 300, it forms a fixed ring for the belt 400 to pass through; the power supply 100 and the rotatable connecting member 200 and the propeller 300 respectively set on both sides form a semi-circular body, which is adapted to the human waist.

[0054] Referring to Figures 1 to 4, a non-limiting embodiment of the present invention illustrates a split-type waist belt 400 comprising a first waist belt 410 and a second waist belt 420, each made of a soft material. Both the first waist belt 410 and the second waist belt 420 are adjustable belts. The first waist belt 410 and the second waist belt 420 are respectively designed to pass through the fixing rings on the two thrusters 300 to form a detachable connection with the thrusters 300. The first waist belt 410 and the second waist belt 420 pass through the fixing rings on the thrusters to form a quick-connect buckle. In this embodiment, the waist belt 400 is a split-type belt 400, primarily made of a soft material. The first waist belt 410 and the second waist belt 420 pass through the fixing rings on the outer ends of the thrusters 300, and then are detachably connected to the respective ends. Compared to existing fixed, snap-on mechanical belts 400, this design offers greater flexibility and a wider range of uses, without the corrosion-prone connection difficulties associated with mechanical belts 400.

[0055] 1 to 4 , a non-limiting embodiment of the present invention is shown, in which the propeller 300 includes a propeller housing 310 and a thrust structure 320 , wherein the propeller housing 310 includes an upper shell 311 and a lower shell 312 , and the upper and lower parts of the thrust structure 320 are snap-connected to the upper shell 311 and the lower shell 312 , respectively. In this embodiment, the propeller 300 includes a propeller housing 310. The setting of the propeller housing 310 is used to place the propeller 300 booster structure 320 inside the propeller housing 310, avoiding the problem of the propeller 300 being exposed to the outside and increasing the underwater forward resistance in the prior art, effectively reducing the resistance of the propeller 300 during the propulsion process, and improving the propulsion effect of the propeller 300; the propeller housing 310 adopts a split structure consisting of an upper shell 311 and a lower shell 312, and the upper and lower parts of the booster structure 320 are respectively snap-connected to the upper shell 311 and the lower shell 312 of the propeller housing 310, which facilitates the installation of the booster structure 320. During installation, one end of the booster structure 320 can be snap-connected and installed with the upper shell 311 or the lower shell 312 first, and then the other end can be installed. The installation is convenient and quick.

[0056] Referring to Figures 4 to 8 , in a non-limiting embodiment of the present invention, the booster structure 320 includes a duct 321 and a propeller 322 positioned within the duct 321. A gap of less than 1 mm is provided between the outer edge of the propeller 322 and the inner surface of the duct 321. A motor 323 is mounted within the duct 321, and the propeller 322 is secured to the output shaft of the motor 323. In this embodiment, the propeller 322 is rotationally driven by the motor 323. The gap between the propeller 322 and the inner surface of the duct 321 is less than 1 mm. This smaller gap can enhance the thrust of the booster structure 320, thereby improving the rotational efficiency of the propeller blades 3222.

[0057] Referring to Figures 4 to 8 , in a non-limiting embodiment of the present invention, the inner surface of the duct 321 is an arcuate surface. The diameter of the duct 321 at the portion corresponding to the propeller 322 is smaller than the diameter of the duct 321 at the inlet and outlet ends of the duct 321. In this embodiment, the inner surface of the duct 321 is designed with a larger diameter at the inlet and outlet ends and a smaller diameter in the middle. After water enters the propeller blades 3222, it flows through the highest part of the arc and into the outlet end, effectively increasing the water flow speed and efficiency, thereby improving the propulsion efficiency of the propeller 300.

[0058] 9 and 10 , in a non-limiting embodiment of the present invention, the propeller 322 is composed of a propeller cap 3221 and three blades 3222 evenly distributed on the outer periphery of the propeller cap 3221. The blades 3222 are spirally arranged on the outer periphery of the propeller cap 3221, and the cross-section of the blades 3222 is shaped like a wing with a thick center and thin sides. In this embodiment, the blades 3222 adopt a wing-shaped structure with a thick center and thin sides. Compared with the flat-plate structure blades 3222 in the prior art, the wing-shaped blades 3222 have greater power, thereby improving the propulsion effect of the entire propeller 300.

[0059] 9 and 10 , in a non-limiting embodiment of the present invention, both the water inlet edge 3223 and the water outlet edge 3224 of the blade 3222 are curved edges, and the curvature of the water outlet edge 3224 is greater than that of the water inlet edge 3223. In this embodiment, the design of the curved water inlet edge 3223 and the water outlet edge 3224 is more conducive to water inflow and outflow; the structural design in which the curvature of the water outlet edge 3224 is greater than that of the water inlet edge 3223 increases the contact area between the water inlet edge 3223 of the blade 3222 and the water. When the motor 323 drives the blade 3222 to rotate, the amount of water entering the blade 3222 is greater than the amount of water leaving the blade 3222, thereby increasing the rotational power of the blade 3222 and effectively improving the propulsion effect of the propeller 300.
