Description

Technical Field

[0001] This utility model relates to the field of floating equipment technology, and in particular to an electric floating board. Background Technology

[0002] Swimming, surfing, and other water sports are popular among the general public, but learning to swim and surf has certain technical difficulties and limitations. Traditional auxiliary equipment for swimming and water activities relies on life rings, life jackets, and inflatable boats, but these devices can only be operated by human power and will stop when no one is there to operate them, which greatly reduces the enjoyment of the activity.

[0003] In view of the above-mentioned technical problems, powered floating platforms have been developed. During use, the floating platform is automatically controlled by a pump propulsion system, which greatly satisfies the user's need for automatic operation.

[0004] For example, utility model patent application number 201822142447.9 provides a technical solution where the front of the powered float is a semi-elliptical plane, with handrails along its perimeter. A pump-driven propulsion system is located on the rear side of the bottom of the float. Swimmers or those playing in the water can lie on the float, and when the pump-driven propulsion system is activated, they receive a boost to propel themselves on the water. The pump-driven propulsion system of the powered float includes two propulsion pumps, positioned on either side of the rear of the float. This technology increases the propulsion force through the two pumps, and the dual-direction output makes the pump thrust on both sides of the float more stable. However, some problems exist, such as the need for two propulsion pumps, which increases costs.

[0005] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model proposes an electric floating platform, which aims to solve the problem of high cost of the existing dual-pump propulsion technology.

[0007] To solve the above-mentioned technical problems, the basic technical solution proposed by this utility model is as follows:

[0008] An electric floating board includes a floating board body and a pump-driven device disposed on the floating board body. The pump-driven device has a drive motor, a propeller drivenly connected to the output end of the drive motor, and a control power supply electrically connected to the drive motor.

[0009] The bottom rear side of the floating plate body has a downwardly protruding sinking shell. The sinking shell has two drainage channels extending from the front to the rear. The two drainage channels are connected at the front end to form a confluence area. The front end of the sinking shell has a water inlet hole, which allows the confluence area to communicate with the outside to facilitate water flow.

[0010] The propeller is located in the confluence area to pump the water backward through the two drainage channels when the water flows in, thereby generating thrust.

[0011] Furthermore, the two drainage channels are symmetrically distributed along the front-to-back axial direction.

[0012] Furthermore, the sunken bottom shell forms an assembly area on the rear side of the confluence area, and the drive motor is assembled in the assembly area.

[0013] Furthermore, the confluence area has a protective cover with its front and rear sides open to facilitate water flow; the propeller is located inside the protective cover.

[0014] Furthermore, the front side of the protective cover has a filter screen to block debris.

[0015] Furthermore, the floating board body also includes a front panel and a middle panel, the middle panel having a sealed cavity, the control power supply being located within the sealed cavity, and the front panel covering the middle panel.

[0016] Furthermore, the middle panel and the sunken bottom shell are combined to form the confluence area and the drainage channel.

[0017] Furthermore, one of the inner surfaces of the panel and the middle panel opposite each other has a positioning groove, and the other has a protrusion that positions and engages with the positioning groove; when the panel and the middle panel are closed, the positioning groove and the protrusion are adapted to achieve lateral positioning.

[0018] Furthermore, the front two sides of the floating board body have handles near the edges.

[0019] Furthermore, the control power supply is electrically connected to a control button, which is located on one of the handles.

[0020] The beneficial effects of this utility model are:

[0021] This utility model proposes an electric floating platform, comprising a floating platform body and a pump-driven device, which includes a drive motor, a propeller, and a control power supply. The bottom rear side of the floating platform body has a downwardly protruding submerged shell. The submerged shell has two drainage channels extending from the front to the rear, which connect at the front end to form a confluence area. The front end of the submerged shell has a water inlet, which connects the confluence area to the outside to facilitate water flow. The propeller, located in the confluence area, pumps the water backward through the two drainage channels to generate thrust when water enters. This solution achieves dual pump output using only one drive motor through the specific arrangement of the two drainage channels. Compared to traditional two power units, this solution satisfies the power output requirements and reduces costs. Attached Figure Description

Detailed Implementation

[0032] The following will be combined with the appendix Figure 1 To be continued Figure 8 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0033] It should be noted that, in the embodiments of this utility model, the directions involved are as shown in the accompanying drawings. If a specific posture changes, the directional indication will also change accordingly.

[0034] This invention achieves the function of having two pump thrust outputs with only one drive motor through a specific drainage channel design. This satisfies the driving requirements of the platform while reducing costs. Specifically, it sets up two drainage channels connected at the confluence end, and arranges a pump-driven propulsion device at the confluence end to achieve two high-speed water flow outputs, thus realizing the function of two outputs from a single power system.

[0035] Detailed, such as Figure 1 and Figure 2 As shown, the electric floating board of this utility model includes a floating board body 10. The floating board body 10 can float on the water surface. Specifically, the floating board body 10 is configured to have a front panel 102, a middle panel 103, and a submerged bottom shell 101. The front panel 102, the middle panel 103, and the submerged bottom shell 101 are sequentially joined together in the thickness direction to form the floating board body 10.

[0036] To facilitate the use of the electric float, the front two sides of the float body 10 have handles 105 near the edges. When in use, the user simply grips the handles 105.

[0037] The panel 102 and the middle panel 103 can be assembled by means of gluing, fastening, interference fit, etc.

[0038] Specifically, such as Figure 2 and Figure 6As shown, to achieve better positioning of panel 102 and middle panel 103, corresponding limiting structures are provided in the mating surface area of ​​the two. Specifically, one of the inner surfaces of panel 102 and middle panel 103 has a positioning groove, and the other has a protrusion that positions and engages with the positioning groove; when panel 102 and middle panel 103 are closed, the positioning groove and the protrusion adapt to achieve lateral positioning. That is, the positioning groove and the protrusion cooperate to achieve limiting between panel 102 and middle panel 103. Specifically, the lateral shape and size of the positioning groove and the protrusion are adapted, so that when the two are just fitted together, there will be no lateral wobbling, thereby ensuring the positioning and assembly between panel 102 and middle panel 103. In one embodiment, as... Figure 6 As shown, a positioning groove 1021 is provided on the lower surface of the panel 102, and a protrusion 1034 corresponding to the positioning groove 1021 is provided on the upper surface of the intermediate panel 103. Thus, when the panel 102 is placed on the intermediate panel 103, the protrusion 1021 fits perfectly into the positioning groove 1034. Of course, the number and shape of the protrusion 1034 and the positioning groove 1021 can be matched according to actual needs. For example, two positioning grooves 1021 can be provided on the front side and two more on the rear side of the lower surface of the panel 102. This method ensures a proper fit between the panel 102 and the intermediate panel 103.

[0039] In one specific embodiment, the intermediate panel 103 has a sealed cavity 104. The electrical-related structures of this electric floating platform are housed within the sealed cavity 104 to protect them. Figure 3 As shown, the middle panel 103 has a mounting groove 1031, on which a box 1032 is fitted. The opening of the box 1032 is sealed with a sealing cap. That is, in this embodiment, the sealed cavity 104 is formed by the sealing fit between the box 1032 and the sealing cap 1033.

[0040] Detailed, such as Figure 5 and Figure 8 As shown, the electric floating platform of this utility model also includes a pump-driven device 20 disposed on the floating platform body 10. The pump-driven device 20 has a drive motor 201, a propeller 202 that is driven and connected to the output end of the drive motor 201, and a control power supply 205 that is electrically connected to the drive motor 201. The control power supply 205 is assembled in the sealed cavity 104 to isolate it from the water.

[0041] To achieve dynamic control of the floating platform, in this embodiment, the control power supply 205 is electrically connected to a control button 204, which is located at one of the handle portions 105. Positioning the control button 204 on the handle portion 105 facilitates control of the drive motor 201 during use. Use is achieved simply by pressing the control button 204. The control power supply 205 includes an electronic control board and a power source, which are electrically connected to the power source, the control button 204, and the drive motor 201. When the control button 105 is pressed, it sends a signal to the electronic control board, which then controls the drive motor 201. In this embodiment, the electronic control board uses a common technology in the art and will not be described in detail. The power source can be, for example, a lithium battery.

[0042] like Figure 2 and Figure 4 As shown, the bottom rear side of the floating plate body 10 has a downwardly protruding submerged shell 101. The submerged shell 101 has two drainage channels 1011 extending from the front to the rear. The two drainage channels 1011 communicate at the front end to form a confluence area 1012. The front end of the submerged shell 101 has a water inlet 1013, which allows the confluence area 1012 to communicate with the outside to facilitate water flow. The propeller 202 is located in the confluence area 1012 to pump the water flow backward through the two drainage channels 1011 when the water flows in, generating thrust.

[0043] The technical solution of this utility model forms two drainage channels 1011 to realize the pumping of two high-speed water flows to generate pumping force.

[0044] Specifically, such as Figure 2 and Figure 4 As shown, the two drainage channels 1011 converge at the front end, forming a confluence area 1012. A corresponding inlet hole 1013 is provided at the front end of the confluence area 1012. In practical use, water enters the confluence area 1012 through the inlet hole 1013 and is split into two high-speed water flows at the confluence area 1012. These two high-speed water flows are discharged backward through the two drainage channels 1011, forming pump thrust. It should be noted that in this embodiment, the propeller 202 is located at the confluence area 1012, and the propeller 202 discharges water backward under the action of the drive motor 201. Since the confluence area 1012 is precisely at the confluence point of the two drainage channels 1011, the high-speed water flow discharged by the propeller 202 can be discharged to both sides at the confluence area 1012 and then enter the corresponding drainage channels 1011. This achieves the dual output by splitting the high-speed water flow into two paths through a drive motor 201 and two drainage channels 1011.

[0045] In this embodiment, the two drainage channels 1011 are symmetrically distributed along the front-to-back axial direction. This ensures that the two high-speed water flows have the same flow path, thereby ensuring that the output pump thrust tends to be balanced. Furthermore, to ensure that the pump thrust output by the high-speed water flow acts on the float body 10 to drive it forward, the outlets of the two drainage channels 1011 are parallel to the front-to-back axial direction of the float body 10. That is, the outlets of the two drainage channels 1011 are parallel and parallel to the forward direction axial direction of the float body 10.

[0046] Preferably, the cross-sections of the confluence area 1012 and the drainage channel 1011 are circular, and the diameter of the confluence area 1012 is larger than the diameter of the drainage channel 1011. For example, the ratio of the diameter of the confluence area 1012 to the diameter of the drainage channel 1011 is between 2:1 and 1.5:1; of course, in practice, it is not limited to this ratio, and other feasible ratios can be used. Simply changing the diameter should fall within the protection scope of this utility model.

[0047] In one specific embodiment, the intermediate panel 103 and the sunken bottom shell 101 are closed to form the confluence area 1012 and the drainage channel 1011. That is, the two drainage channels 1011 and the confluence area 1012 are formed by the intermediate panel 103 and the sunken bottom shell 101 being closed together. Figure 4 As shown, the drainage channel 1011 and the confluence area 1012 are partially formed on the opposing surfaces of the intermediate panel 103 and the sunken bottom shell 101, respectively. Thus, after the intermediate panel 103 and the sunken bottom shell 101 are closed, a portion of the intermediate panel 103 aligns with a portion of the sunken bottom shell 101 to form a complete drainage channel 1011 and confluence area 1012. Specifically, corresponding structures are formed on the panel 103 and the sunken bottom shell 101 along the direction of water flow, allowing for easy closing. For example, as... Figure 4 As shown, the drainage channel 1011 includes a lower drainage area 10111 formed at the lower bottom shell 101 and an upper drainage area 10112 formed at the middle panel 103. Thus, the drainage channel 1011 is formed after the middle panel 103 and the lower bottom shell 101 are joined together. The corresponding confluence area 1012 is configured the same as the drainage channel 1011, and will not be described in detail here.

[0048] In addition, such as Figure 2 , Figure 4 and Figure 7As shown, the recessed bottom shell 101 forms an assembly area 1014 on the rear side of the junction area 1012, and the drive motor 201 is assembled in the assembly area 1014. Preferably, the assembly area 1014 is jointly formed by the recessed bottom shell 101 and the intermediate panel 103, that is, when the recessed bottom shell 101 and the intermediate panel 103 are closed, they together form the assembly area 1014. Furthermore, the recessed bottom shell 101 and the intermediate panel 103 respectively abut against the corresponding drive motor 201 to fix the drive motor 201.

[0049] In addition, such as Figure 5 As shown, the confluence area 1012 has a protective cover 203, which is open at both the front and rear sides to facilitate water flow; the propeller 202 is disposed inside the protective cover 203. Specifically, the protective cover 203 ensures that the propeller 202 will not contact the side wall of the confluence area 1012 during rotation, thus protecting the side wall of the confluence area 1012. To ensure the strength of the protective cover 203, in this embodiment, the protective cover 203 is made of, for example, stainless steel. This ensures strength, prevents corrosion, and extends its service life.

[0050] For details, please refer to Figure 7 To secure the protective cover 203, an annular mounting groove 10121 is provided at the junction area 1012. The outer diameter of the annular mounting groove 10121 is larger than the outer diameter of the junction area 1012. The outer diameter of the protective cover 203 matches the outer diameter of the annular mounting groove 10121. Thus, when the protective cover 203 is assembled in the annular mounting groove 10121, the stepped limiting structure 10122 formed between the annular mounting groove 10121 and the sidewall of the junction area 1012 provides a limiting effect on the protective cover 203, preventing it from falling off.

[0051] In one specific embodiment, to prevent debris from being drawn into the confluence area 1012 during use and affecting the operation of the propeller 202, the front side of the protective cover 203 has a filter screen 2031 to block debris. Larger objects will be blocked by this filter screen 2031. It should be understood that the filter screen 2031 in this embodiment has sufficient porosity to ensure that water can pass through it and enter the confluence area 1012. The filter screen 2031 and the protective cover 203 are assembled together in the annular mounting groove 10121 to secure the filter screen 2031.

[0052] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
