[0045] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some technical features known in the art are not described.

[0046] In order to fully understand the implementation of the present invention, a detailed structure will be presented in the following description. Obviously, the implementation of the implementation of the present invention is not limited to the specific details familiar to those skilled in the art.

[0047] It should be understood that the purpose of the terms used herein is only to describe specific embodiments and is not intended to limit the present invention, and the singular forms "a", "an" and "said / the" are also intended to include plural forms, unless the context clearly indicates otherwise. When the terms "comprise" and / or "include" are used in this specification, it indicates the presence of the features, integral bodies, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integral bodies, steps, operations, elements, components and / or combinations thereof.

[0048] Ordinal numbers such as "first" and "second" cited in the present invention are merely identifiers and do not have any other meaning, such as a specific order. Moreover, for example, the term "first component" itself does not imply the existence of a "second component", and the term "second component" itself does not imply the existence of a "first component". It should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inner", "outer" and similar expressions used in the present invention are for illustrative purposes only and are not limiting.

[0049] The "parallel" / "vertical" and similar expressions used in the present invention include an absolute parallel / vertical relationship and a roughly parallel / vertical relationship (for example, a relationship that differs from absolute parallel / vertical by -5° to +5°), which can have the same effect.

[0050] Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings. These drawings show representative embodiments of the present invention and are not intended to limit the present invention.

[0051] In order to enable the vehicle to travel both on land and in water, the related technologies mostly adopt the solution of directly adding additional water thrusters. The inventors found that the related technologies will reduce the ground clearance of the vehicle, and the water thrusters cannot change their position in the height direction, thus affecting the vehicle's driving on land.

[0052] The utility model provides a floating drive device and a vehicle. The floating drive device here is located at the bottom of the vehicle body, for example, connected to the chassis of the vehicle. The paddle wheel in the floating drive device moves to a storage position and a working position in the height direction or vertical direction of the vehicle. When the paddle wheel is located at the storage position, the paddle wheel can ensure that the vehicle has sufficient ground clearance to meet the needs of the vehicle traveling on land. When the paddle wheel is located at the working position, the paddle wheel is located at a lower position, which is convenient for the vehicle to rotate when wading to generate a thrust force, thereby enabling the vehicle to wade. The paddle wheel here can be integrated with the spare tire. While simplifying the structure of the vehicle, more available space can also be reserved for the interior of the vehicle.

[0053] See below Figures 1 to 5 The illustrated example describes in detail the floating water drive device and the vehicle according to the present invention.

[0054] The floating drive device according to the present utility model may include a rotating arm 121 and a paddle wheel assembly 128. The rotating arm 121 has a first end 121a and a second end 121b spaced apart along its own length direction D4. The first end 121a of the rotating arm 121 is suitable for being rotatably connected to the bottom of the vehicle body 110 around a first axis AX1. When the rotating arm 121 is connected to the vehicle body 110, the second end 121b of the rotating arm 121 can change position in the height direction D1 or vertical direction of the vehicle 100 when the rotating arm 121 rotates around the first axis AX1. The first axis AX1 intersects with the length direction D4. The paddle wheel assembly 128 is disposed at the second end 121b of the rotating arm 121 to rotate with the second end 121b around the first axis AX1 to a storage position (such as Figure 1 and Figure 3 as shown) and working position (as Figure 2 121b of the rotating arm 121 and is connected to the paddle wheel 122. The first driving member 123 is adapted to drive the paddle wheel 122 to rotate about the second axis AX2. The second axis AX2 intersects the first axis AX1. When the paddle wheel assembly 128 is in the working position and the paddle wheel 122 rotates in the liquid about the second axis AX2, the paddle wheel assembly 128 can generate a thrust force.

[0055] When the floating water driving device 120 is applied to the vehicle 100, the first axis AX1 may be parallel to the width direction D2 or the left-right direction of the vehicle 100. Figures 1 to 3 As shown, the impeller assembly 128 in the storage position is higher in the height direction D1 than the impeller assembly 128 in the working position. Figure 1 and Figure 3 ), the second axis AX2 may be parallel to or nearly parallel to the height direction D1 of the vehicle 100. When the paddle wheel assembly 128 is in the working position (as shown in FIG. Figure 2 As shown), the second axis AX2 can be parallel to or nearly parallel to the front-rear direction D3 of the vehicle 100, so as to be suitable for generating a forward or backward thrust.

[0056] According to the floating drive device 120 of the utility model, when the floating drive device 120 is applied to the vehicle 100, the rotating arm 121 can rotate relative to the body 110 of the vehicle 100 around the first axis AX1, so as to drive the paddle wheel assembly 128 to rotate to the storage position and the working position. When the paddle wheel assembly 128 is in the storage position, the influence of the floating drive device 120 on the ground clearance of the vehicle 100 can be reduced, thereby ensuring that the vehicle 100 can be suitable for driving on land. When the paddle wheel assembly 128 is in the working position, the paddle wheel 122 is driven to rotate by the first driving member 123, and a thrust force can be generated in the liquid, so that the vehicle 100 can be suitable for driving in a wading environment.

[0057] See also Figure 3 and Figure 5 For example, the first driving member 123 is a first motor. One of the housing and the output shaft of the first motor is fixedly arranged relative to the rotating arm 121. The other of the housing and the output shaft of the first motor is fixedly arranged relative to the impeller assembly 128. When the first motor is started, the impeller 122 can be driven to rotate.

[0058] Optionally, the output shaft of the first motor may be arranged coaxially with the second axis AX2. The output shaft of the first motor may not be arranged coaxially with the second axis AX2. In the case where the output shaft of the first motor is not arranged coaxially with the second axis AX2, the output shaft of the first motor may be connected to the impeller 122 via a transmission structure to transmit power to the impeller 122 via the transmission structure.

[0059] Continue reading Figure 3 and Figure 5 In addition, the floating drive device 120 may further include a telescopic assembly 126. One end of the telescopic assembly 126 is connected to the bottom of the vehicle body 110. The other end of the telescopic assembly 126 is directly or indirectly connected to the rotating arm 121. The telescopic assembly 126 is spaced apart from the first axis AX1. The telescopic assembly 126 is configured to be adjustable in length so that the rotating arm 121 rotates. Here, the rotation of the rotating arm 121 is adjusted by changing the length of the telescopic assembly 126, so that the paddle wheel assembly 128 moves to the storage position or the working position.

[0060] Furthermore, the floating drive device 120 may further include a second drive member 124. The second drive member 124 is transmission-connected to the telescopic assembly 126 to drive the telescopic assembly 126 to change its length. When in use, the purpose of driving the telescopic assembly 126 to change its length can be achieved by starting the second drive member 124.

[0061] See also Figure 3 and Figure 5In one example, the telescopic assembly 126 may include a first link 126a and a second link 126b. One end of the first link 126a is pivotally connected to one end of the second link 126b around the third axis AX3. The end of the first link 126a away from the third axis AX3 is suitable for pivotally connecting to the bottom of the vehicle body 110 around the fourth axis AX4. The end of the second link 126b away from the third axis AX3 is rotatably arranged around the fifth axis AX5 and is transmission-connected to the second driving member 124. The third axis AX3, the fourth axis AX4, and the fifth axis AX5 are all parallel to the first axis AX1. When the floating drive device 120 is applied to the vehicle 100, when the impeller assembly 128 is located in the storage position, the first link 126a and the second link 126b are close to each other and arranged in a folded posture, and at this time, the fourth axis AX4 and the fifth axis AX5 are closest to each other in the height direction D1 of the vehicle 100. When the paddle wheel assembly 128 is in the working position, the first link 126a and the second link 126b are separated from each other and arranged in an extended posture, and at this time, the fourth axis AX4 and the fifth axis AX5 are at the farthest distance in the height direction D1 of the vehicle 100. Here, the second link 126b is driven by the second driving member 124 to rotate around the fifth axis AX5, thereby changing the angle between the first link 126a and the second link 126b in the circle centered on the third axis AX3, so that the posture of the combination of the first link 126a and the second link 126b is changed to a folded posture or an extended posture, and finally the paddle wheel assembly 128 is rotated with the rotating arm 121 around the first axis AX1 to the storage position or the working position.

[0062] In another example not shown, the second driving member 124 may be drivingly connected to the end of the first connecting rod 126a away from the third axis AX3. The second driving member 124 is suitable for driving the first connecting rod 126a to rotate around the fourth axis AX4.

[0063] In other examples not shown, the telescopic assembly 126 may also be configured as a telescopic rod structure.

[0064] For example, the second driving member 124 is a second motor.

[0065] Optionally, the output shaft of the second motor may be coaxially arranged with the fifth axis AX5. The output shaft of the second motor may not be coaxially arranged with the fifth axis AX5. In the case where the output shaft of the second motor is not coaxially arranged with the fifth axis AX5, the output shaft of the second motor may be connected to the second connecting rod 126b through a transmission structure to transmit power to the second connecting rod 126b through the transmission structure.

[0066] See also Figure 3 and Figure 5In addition, the floating drive device 120 may further include a reduction assembly 125. The reduction assembly 125 may include a power input end and a power output end. The transmission ratio of the power input end and the power output end of the reduction assembly 125 is less than 1. The power input end is transmission-connected to the second motor. The power output end is transmission-connected to the end of the second connecting rod 126b to transmit power between the second motor and the second connecting rod 126b. Here, the power output by the second motor is decelerated and torque-increased by the reduction assembly 125. The power after deceleration and torque-increase by the reduction assembly 125 is transmitted to the end of the second connecting rod 126b, so that the second connecting rod 126b can be smoothly and reliably driven to rotate.

[0067] For example, the reduction assembly 125 here can be one of a belt transmission assembly, a gear transmission assembly, a chain transmission assembly, or any combination thereof.

[0068] See also Figures 2 to 4 For example, the paddle wheel 122 may include a hub 122a, a rim 122b, a paddle 122c and a tire 122d. The rim 122b is sleeved on the outside of the hub 122a and is arranged concentrically with the hub 122a. The paddle 122c is connected between the rim 122b and the hub 122a to form a spoke. The paddle 122c and the hub 122a together form a propeller. The propeller is configured to form a thrust along the axial direction of the hub 122a when rotating in a liquid. The tire 122d is sleeved on the outside of the rim 122b. The paddle wheel 122, which is equipped with the tire 122d and filled with gas, may have a density lower than that of water, and may increase the buoyancy of the floating drive device 120. The impeller 122 here can be understood as an integration of a propeller and a wheel, so that the impeller 122 can be used as a spare tire, which is conducive to making full use of the spare tire of the vehicle 100 to realize the floating drive device 120.

[0069] See also Figure 3 Further, the impeller 122 may include a recessed portion 122e that is recessed in a direction parallel to the second axis AX2. The first drive member 123 is at least partially accommodated in the recessed portion 122e. By properly utilizing the space of the recessed portion 122e of the impeller 122 to accommodate the first drive member 123, the first drive member 123 can reduce the external space occupied by the external space, thereby facilitating the reduction of the external dimensions of the floating drive device 120.

[0070] See also Figure 3 and Figure 5In addition, the floating drive device 120 may further include a flip seat. The flip seat is connected to the second end 121b of the rotating arm 121. The first driving member 123 and the paddle wheel 122 are connected to the flip seat. The installation position of the rotating arm 121 on the flip seat is staggered with the installation position of the first driving member 123 on the flip seat. By providing the flip seat, it is convenient to establish the connection between the rotating arm 121, the first driving member 123 and the paddle wheel 122.

[0071] Further, the flip seat can be a housing of a first motor as the first driving member 123. The second motor as the second driving member 124 is fixed to the housing of the first motor. The impeller 122 is detachably connected to the output shaft of the first motor.

[0072] In the utility model, the paddle wheel 122 can be consistent with the spare tire of the conventional vehicle 100. The density of the paddle wheel 122 is less than that of water, which enables the paddle wheel 122 to generate buoyancy after entering the water. The paddle wheel 122 rotates after entering the water to stir the water flow to generate a reaction force. The propeller structure of the paddle wheel 122 has a certain rigidity to ensure the normal driving of the paddle wheel 122 on land. The paddle wheel 122 can be installed on the output shaft flange of the first motor as the first driving member 123. The first motor is the power source of the floating drive device 120, which can have waterproof performance, so as to ensure that the first motor can also work normally when it moves into the water with the paddle wheel 122. The housing of the first motor can be set as an integral part with the rotating arm 121. The end of the rotating arm 121 away from the first motor can be installed at the bottom of the vehicle body 110 through a pin. The housing of the first motor can also have a mounting structure suitable for installing a second motor as the second driving member 124. The housing of the first motor may further be provided with a support arm 127 for mounting the telescopic assembly 126. The second connecting rod 126b of the telescopic assembly 126 may be mounted on the support arm 127 via a pin. The first connecting rod 126a of the telescopic assembly 126 may be pivotally mounted on the bottom of the vehicle body 110 via a pin. The first connecting rod 126a and the second connecting rod 126b may be pivotally connected via a pin. When the second motor outputs power, the telescopic assembly 126 extends, so that the paddle wheel assembly 128 turns around the first axis AX1 with the rotating arm 121 and enters the water. The power provided by the second motor is transmitted to the telescopic assembly 126 after being decelerated and torque-increased by the reduction assembly 125, thereby driving the entire floating drive device 120 to move, and causing the paddle wheel assembly 128 to gradually enter the water. The reduction assembly 125 and the second motor may also have waterproof properties so that the vehicle 100 is suitable for traveling in a wading environment with a deeper water level.

[0073] In the present invention, the first motor can rotate forward or reverse, so that the floating drive device 120 can push the vehicle 100 forward or backward in a wading environment. In the present invention, the method of disassembling the paddle wheel 122 as a spare tire can be the same as that of a conventional vehicle 100.

[0074] The utility model is a floating driving device 120 installed at the bottom of a vehicle body 110. The paddle wheel assembly 128 can selectively rotate with the rotating arm 121 around the first axis AX1 to one of the storage position and the working position. When the vehicle 100 needs to be driven by floating water, the second driving member 124 is started to drive the telescopic assembly 126 to extend, so that the paddle wheel assembly 128 moves to the working position, and then the paddle wheel 122 is driven to rotate by the first driving member 123, which can generate a thrust force in the water to make the vehicle 100 travel. When the vehicle 100 is traveling on land, the second driving member 124 is started to drive the telescopic assembly 126 to shorten, so that the paddle wheel assembly 128 moves to the storage position, and then the paddle wheel assembly 128 is retracted, thereby reducing the impact on the vehicle 100 traveling on land.

[0075] See also Figure 1 and Figure 2 , combined with Figures 3 to 5 The utility model further provides a vehicle 100. The vehicle 100 may include a vehicle body 110 and the above-mentioned floating water driving device 120. The paddle wheel 122 of the paddle wheel assembly 128 is a spare tire of the vehicle 100. The floating water driving device 120 is connected to the bottom of the vehicle body 110.

[0076] According to the vehicle 100 of the utility model, by applying the above-mentioned floating drive device 120, the spare tire and propeller of the vehicle 100 are integrated into the paddle wheel 122, which simplifies the structure and is also conducive to freeing up more use space for the interior of the vehicle 100. It can not only travel on land like the traditional vehicle 100, but also travel in water when the vehicle 100 wades. The floating drive device 120 of the utility model can change the position of the paddle wheel assembly 128 as needed, and integrate the water propulsion device with the spare tire installed at the bottom of the vehicle body 110. In this way, the vehicle 100 can not only achieve the ability to travel on water when floating, but also solve the problem that the vehicle 100 of the related art is affected by the addition of a device that adapts to the function of traveling on water. Since the paddle wheel assembly 128 can be flipped to the storage position with the rotating arm 121, the vehicle 100 can be consistent with the traditional vehicle 100 without adding the floating drive device 120 when traveling on land, or the appearance of the vehicle 100 of the utility model is slightly changed compared with the traditional vehicle 100. Moreover, when in use, the rotation angle of the rotating arm 121 can be adjusted according to the water level, so as to change the posture of the floating drive device 120 in the water, and then adjust the driving posture of the vehicle 100, so as to improve the stability of the vehicle 100 driving on the water. The density of the paddle wheel assembly 128 of the floating drive device 120 is less than the density of water, so that the buoyancy of the whole vehicle can be increased after the paddle wheel assembly 128 enters the water. The connection mode of the paddle wheel 122 and the first driving member 123 in the utility model can refer to the connection mode of the traditional spare tire and the vehicle body 110, so as not to affect the disassembly and installation of the paddle wheel 122 as the spare tire. Compared with the prior art, the utility model uses the original design space for land driving to arrange the floating drive device 120 without additionally increasing the design space and not affecting the vehicle 100 driving on land, so as to realize the function of the vehicle 100 driving on the water. In this way, the vehicle 100 of the utility model has the advantages of higher functional integration, more compact space design, and more convenient disassembly and assembly.

[0077] The working mode of the utility model can be as follows:

[0078] The user inputs a command when he thinks that the vehicle 100 needs to be driven by floating water. The second motor starts to operate according to the command, and the power output by the second motor is transmitted to the second connecting rod 126b of the telescopic assembly 126 after being decelerated and torque-increased by the reduction assembly 125. The second connecting rod 126b rotates around the fifth axis AX5, so that the first connecting rod 126a and the second connecting rod 126b of the telescopic assembly 126 are gradually unfolded, thereby driving the rotating arm 121 and the paddle wheel assembly 128 to rotate around the first axis AX1 to the working position, so that the paddle wheel assembly 128 enters the water. After the paddle wheel assembly 128 enters the water and the rotating arm 121 rotates to a suitable angle, the second motor stops working, and then the first motor starts working and drives the paddle wheel 122 to rotate. Because the paddle wheel 122 has a propeller structure, its rotation stirs the water flow to generate a reaction force, thereby driving the vehicle 100 to travel.

[0079] After the vehicle 100 is driven by floating water, the utility model can control the second motor to reverse, so as to drive the rotating arm 121 and the impeller assembly 128 to rotate around the first axis AX1 to the storage position, so that the floating driving device 120 is retracted, thereby increasing the ground clearance of the floating driving device 120. At this time, the vehicle 100 can be consistent with a conventional vehicle 100 when driving on land.

[0080] In summary, the utility model is a floating driving device 120 and a vehicle 100, which cleverly integrates the floating driving device 120 of the vehicle 100 with the spare tire installed at the bottom of the vehicle body 110, and uses the rotating arm 121 to drive the paddle wheel assembly 128 to flip to the working position, so as to realize the vehicle 100 traveling on water.
