[0034] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0035] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0036] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0037] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0038] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0039] According to one embodiment of this application, a floating drive device is provided. For example... Figures 1 to 6 As shown, the floating drive device includes a wheel 03, a first drive mechanism 302, and a second drive mechanism 201. The wheel 03 has a propeller structure 308. The first drive mechanism 302 is connected to the propeller structure 308 and can drive the propeller structure 308 to rotate; the second drive mechanism 201 is connected to the wheel 03 and can drive the wheel 03 to rotate between a first position and a second position.

[0040] In this example, wheel 03 has a propeller structure 308, a first drive mechanism 302 is connected to the propeller structure 308, the first drive mechanism 302 can drive the propeller structure 308 to rotate, and a second drive mechanism 201 is connected to wheel 03, the second drive mechanism 201 can drive wheel 03 to rotate between a first position and a second position, thereby avoiding the floating drive device from affecting the vehicle's travel on land.

[0041] In this example, the second drive mechanism 201 can rotate wheel 03 to a second position. At this time, the first drive mechanism 302 can rotate wheel 03, thereby rotating propeller structure 308 to provide propulsion in the water. When driving on land, the second drive mechanism 201 rotates the vehicle to a first position, thus preventing wheel 03 from being too close to the ground and affecting vehicle movement.

[0042] In this example, such as Figure 7 and Figure 8 As shown, in the first position, the floating drive device is in a non-operating state, and in the second position, the wheel 03 is adapted to provide power or assist steering.

[0043] like Figure 7 As shown, the second drive mechanism 201 drives the wheel 03 to rotate upward to the first position. At this time, the buoyancy drive device is in a non-operating state. The wheel 03 is at a relatively high height from the ground, which can avoid affecting the vehicle's driving on land and can also prevent the buoyancy drive device from being damaged.

[0044] like Figure 8 As shown, the vehicle travels in water. The second drive mechanism 201 drives the wheel 03 to rotate downward to the second position, so that the wheel 03 can be submerged in water. The first drive mechanism 302 can drive the propeller structure 308 to rotate, thereby providing power for the vehicle to travel in water.

[0045] Alternatively, wheel 03 can also be used for steering assistance when in the second position. That is, the second drive mechanism 201 drives wheel 03 to rotate downward to the second position, and then the rear wheels are lifted by the vehicle suspension system so that wheel 03 can contact the ground. At this time, the vehicle is supported by the front wheels and wheel 03, and the first drive mechanism 302 drives wheel 03 to rotate, thereby assisting in vehicle steering or parallel parking.

[0046] In this example, wheel 03 can be the vehicle's spare tire. When the front or rear tires of the vehicle are damaged, wheel 03 can be removed and the damaged tires replaced.

[0047] In this example, the first drive mechanism 302 and the second drive mechanism 201 together constitute the drive assembly 02, which is used to drive the movement of the wheel 03.

[0048] In one example, such as Figure 1 and Figure 4 As shown, the second drive mechanism 201 has a first output shaft 203, and the first drive mechanism 302 has a second input shaft 301. The first output shaft 203 is drively connected to the second input shaft 301, and the first output shaft 203 and the second input shaft 301 are coaxially arranged. The first output shaft 203 of the second drive mechanism 201 and the second input shaft 301 of the first drive mechanism 302 are coaxially arranged. When the second drive mechanism 201 drives the wheel 03 to swing between the first position and the second position, the load on the second drive mechanism 201 can be reduced.

[0049] like Figure 1 and Figure 4 As shown, the first output shaft 203 is fixedly connected to the second input shaft 301. The first drive mechanism 302 is coaxially arranged with the first output shaft 203. When the first output shaft 203 rotates, it only needs to drive the first drive mechanism 302 to rotate around the axis, without driving the first drive mechanism 302 to swing between the first position and the second position, thereby reducing the load on the second drive mechanism 201.

[0050] For example, the first output shaft 203 can be connected to the second input shaft 301 by means of a locating pin or screws. Alternatively, the first output shaft 203 can also be directly connected to the housing of the first motor by welding or screws. Those skilled in the art can decide according to the actual situation, and no specific limitation is made here.

[0051] In one example, such as Figure 4 and Figure 5As shown, the propeller structure 308 is provided with a first input shaft 306, and the first drive mechanism 302 is also provided with a second output shaft 303. The second output shaft 303 is connected to the first input shaft 306 and is arranged parallel to the first input shaft 306.

[0052] like Figure 4 and Figure 5 As shown, the first input shaft 306 of the propeller structure 308 is coaxially arranged with the wheel 03. The first drive mechanism 302 is provided with a second output shaft 303, which is drively connected to the first input shaft 306. The second output shaft 303 can drive the first input shaft 306 to rotate, thereby driving the propeller structure 308 to rotate. The second output shaft 303 is arranged parallel to the first input shaft 306. The second output shaft 303 is coaxially arranged with the second input shaft 301. When the first output shaft 303 rotates, it only needs to drive the first drive mechanism 302 to rotate around the axis, without driving the first drive mechanism 302 to swing between the first position and the second position, thereby reducing the load on the second drive mechanism 201.

[0053] For example, the first drive mechanism 302 includes a first motor with a second output shaft 303, which is drively connected to a first input shaft 306 to drive the wheel 03 to rotate. A second input shaft 301 is also provided on one side of the first motor, which is adapted to connect to the first output shaft 203. Of course, the first drive mechanism 302 can also be other rotary actuators. Those skilled in the art can determine this according to the actual situation, and no specific limitations are made here. The first motor is waterproof to facilitate operation underwater.

[0054] like Figure 4 and Figure 5 As shown, in this example, one end of the first input shaft 306 is fixedly connected to the wheel 03, and the other end of the first input shaft 306 is rotatably connected to the swing arm 305. The first drive mechanism 302 is driven by the first input shaft 306. The first drive mechanism 302 can drive the first input shaft 306 to rotate, thereby driving the wheel 03 to rotate.

[0055] The first input shaft 306 can be connected to the hub 307 of the wheel 03, and the axis of the first input shaft 306 coincides with the axis of the wheel 03, so that the first input shaft 306 can stably drive the wheel 03 to rotate. The hub 307 is provided with a propeller structure 308 in the circumferential direction.

[0056] In one example, such as Figure 4 and Figure 5As shown, the second output shaft 303 is connected to the first input shaft 306 via a second transmission member 304. The second output shaft 303 is also connected to the first input shaft 306 via the second transmission member 304, so that the second output shaft 303 can be located on one side of the first input shaft 306 in the radial direction, and the second output shaft 303 is arranged parallel to the first input shaft 306.

[0057] For example, such as Figure 4 As shown, the second transmission component 304 can be a transmission belt. The transmission belt is respectively sleeved on the second output shaft 303 and the first input shaft 306, and the first motor can drive the first input shaft 306 to rotate through the transmission belt.

[0058] Of course, the second transmission component 304 can also be a transmission chain structure. Those skilled in the art can determine this according to the actual situation, and no specific limitation is made here.

[0059] In one example, such as Figure 1 , Figure 4 and Figure 5 As shown, the floating drive device also includes a swing arm 305, one end of which is connected to the first input shaft 306 and the other end is connected to the first drive mechanism 302.

[0060] like Figure 1 , Figure 4 and Figure 5 As shown, in this example, one end of the swing arm 305 is connected to the first input shaft 306, and the other end is connected to the first drive mechanism 302. When the first output shaft 203 drives the first drive mechanism 302 to rotate, the first drive mechanism 302 can drive the swing arm 305 to rotate, so that the swing arm 305 can drive the wheel 03 to rotate between the first position and the second position.

[0061] In this example, wheel 03 can be connected to the first drive mechanism 302 via swing arm 305, which can improve the stability of wheel 03 and enhance its support capacity.

[0062] For example, the first drive mechanism 302 includes a first motor, and one end of the swing arm 305 away from the first input shaft 306 is fixedly connected to the housing of the first motor. For example, the swing arm 305 can be connected to the first motor by welding or fastening with screws. Those skilled in the art can decide according to the actual situation, and no specific limitation is made here.

[0063] In this example, the swing arm 305 is arranged radially along the wheel 03. The length direction of the swing arm 305 is arranged radially along the wheel 03, one end of the swing arm 305 is connected to the first drive mechanism 302, and the other end is connected to one end of the first input shaft 306.

[0064] like Figure 5and Figure 6 As shown, in this example, wheel 03 has a propeller structure 308, which rotates and can be used for propulsion in water. For example, the spokes of wheel 03 can be set as the propeller structure 308. That is, the hub 307 and the rim are connected by the blades of the propeller structure 308. This makes the entire design space compact and does not occupy too much extra space.

[0065] In this example, the second drive mechanism 201 includes a second motor, which is drively connected to the first output shaft 203. The second motor can drive the first output shaft 203 to rotate. Of course, the second drive mechanism 201 can also be other types of rotary actuators. Those skilled in the art can determine this according to the actual situation, and no specific limitation is made here.

[0066] For example, such as Figure 2 and Figure 3 As shown, the first transmission component 204 includes a speed-changing gear assembly. The second motor is located on one radial side of the first output shaft 203, and is connected to the first output shaft 203 via the speed-changing gear assembly. The speed-changing gear assembly is a reduction gear set from the second motor to the first output shaft 203. Through the reduction gear set, the high-speed, low-torque power output by the second motor is converted into low-speed, high-torque power, and the first output shaft 203 outputs the reduced-torque power to the swing arm 305.

[0067] Of course, the first transmission component 204 can also be a transmission belt, which is respectively sleeved on the first output shaft 203 and the output shaft of the second motor. The second motor can drive the first output shaft 203 to rotate through the transmission belt. The diameter of the output shaft of the second motor is smaller than the diameter of the first output shaft 203, so as to convert the high-speed, low-torque power output by the second motor into low-speed, high-torque power. Alternatively, the first transmission component 204 can also be a chain, etc. Those skilled in the art can decide according to the actual situation, and no specific limitation is made here.

[0068] like Figure 2 and Figure 3 As shown, in this example, the floating drive device further includes a first housing 205 and a second housing 202. The second housing 202 has an inner cavity, in which the second drive mechanism 201, the first transmission member 204, and the first output shaft 203 are disposed. The first output shaft 203 can pass through the side wall of the first housing 205 to connect with the first drive mechanism 202. The first housing 205 is sealed to the open end of the second housing 202. For example, the second housing 205 can be fixedly connected to the first housing 205 by fasteners such as screws or bolts, or the second housing 202 can be snapped to the first housing 205. Those skilled in the art can decide according to the actual situation, and no specific limitation is made here.

[0069] In this example, such as Figures 7 to 9 As shown, wheel 03 can be a spare tire for the vehicle, and the floating drive device is installed on the rear door 101 of the vehicle. The first housing 205 and the second housing 202 are fixedly installed on the inner side of the rear door 101. The swing arm 305 and wheel 03 are located on the outer side of the rear door 101, and the first output shaft 203 passes through the rear door 101 and is connected to the first drive mechanism 302.

[0070] In one example, such as Figure 2 and Figure 3 As shown, the drive assembly 02 also includes a locking member 206. The first output shaft 203 is provided with a plurality of stop grooves 2031 along the circumferential direction. The locking member 206 can be inserted into the stop grooves 2031 to restrict the rotation of the first output shaft 203.

[0071] like Figure 2 As shown, the drive assembly 02 includes a locking member 206, which is disposed within the second housing 202. The first output shaft 203 has multiple stop grooves 2031 along its circumference. When the first output shaft 203 drives the swing arm 305 to rotate to the target position, the locking member 206 can insert into the stop grooves 2031 to restrict the rotation of the first output shaft 203. When the first output shaft 203 needs to rotate, the locking member 206 disengages from the stop grooves 2031. For example, the locking member 206 can be rotated by a motor to insert into or disengage from the stop grooves 2031, or it can be moved by a linear cylinder to insert into or disengage from the stop grooves 2031.

[0072] The locking element 206 can be a pawl structure or a locking pin structure, etc. Those skilled in the art can determine the appropriate type based on the specific circumstances, and no specific limitations are made here.

[0073] According to another embodiment of the present invention, an electrical device is provided. The electrical device includes the floating drive device described in the above embodiment. The floating drive device includes a wheel 03, a first drive mechanism 302, and a second drive mechanism 201. The wheel 03 has a propeller structure 308. The first drive mechanism 302 is connected to the propeller structure 308 and is capable of driving the propeller structure 308 to rotate; the second drive mechanism 201 is connected to the wheel 03 and is capable of driving the wheel 03 to rotate between a first position and a second position.

[0074] In this example, wheel 03 has a propeller structure 308, a first drive mechanism 302 is connected to the propeller structure 308, the first drive mechanism 302 can drive the propeller structure 308 to rotate, and a second drive mechanism 201 is connected to wheel 03, the second drive mechanism 201 can drive wheel 03 to rotate between a first position and a second position, thereby avoiding the floating drive device from affecting the vehicle's travel on land.

[0075] In one example, such as Figures 7 to 9 As shown, the electrical equipment includes a vehicle, and the floating drive device is installed on the rear door 101 of the vehicle.

[0076] Wheel 03 can serve as a spare wheel for the vehicle. A rear door 101 is located on the rear side of the vehicle body 01, and the buoyancy drive device is mounted on the rear door 101. The second drive mechanism 201 is located inside the rear door 101; that is, the first housing 205 and the second housing 202 are fixedly mounted on the inner side of the rear door 101. The swing arm 305 and wheel 03 are located on the outer side of the rear door 101. The first output shaft 203 passes through the rear door 101 and is connected to the first drive mechanism 302, which is then connected to the wheel 03. The wheel 03 is equipped with a propeller structure 308. This design makes the overall spatial structure compact, without occupying too much extra space, and does not affect the vehicle's land-based driving or exterior styling.

[0077] When the driver enters a river or sea, the driver inputs a command to the spare wheel's waterborne propulsion system. Upon receiving the command, the second drive mechanism 201 starts, rotating and outputting power to the first transmission component 204. The first transmission component 204 reduces the speed and increases the torque of the power output from the second drive mechanism 201 and transmits the power to the first output shaft 203. The first output shaft 203 transmits power to the second input shaft 301, causing the swing arm 305 to rotate 180° around the first output shaft 203, thus rotating the wheel 03 from the first position to the second position. Figure 8 The position is shown. At this time, wheel 03 is submerged in water, and wheel 03 can also provide buoyancy for the vehicle. Locking member 206 is activated, inserting into the stop groove 2031 of the first output shaft 203, locking the first output shaft 203, and thus fixing the position of the spare wheel. The first drive mechanism 302 is activated, driving the second output shaft 303 to rotate, and then transmitting power to the first input shaft 306 through the second transmission member 304, ultimately driving the propeller structure 308 and wheel 03 to rotate along the axis of wheel 03. The propeller structure 308 stirs the water flow to generate reaction force, providing the vehicle with forward or backward driving force, thereby driving the vehicle forward or backward.

[0078] When the first output shaft 203 drives the swing arm 305 to rotate around the first output shaft 203, it is only necessary to adjust the spare wheel to be submerged in water. The rotation angle of the swing arm 305 can be determined by those skilled in the art according to the actual situation, and no specific limitation is made here.

[0079] When the driver is in a river or sea and does not need the vehicle to move forward or backward, a command is sent to the first drive mechanism 302. Upon receiving the command, the first drive mechanism 302 stops rotating. At this time, the wheel 03 is submerged in water. Because the spare wheel stores air, it can provide a certain amount of buoyancy to the vehicle, effectively preventing the vehicle from sinking.

[0080] When the driver leaves the river or sea, a command is sent to the second drive mechanism 201, which then starts. The second drive mechanism 201 outputs power to the first transmission component 204, which reduces the speed and increases the torque of the power output from the second drive mechanism 201 and transmits the power to the first output shaft 203. The first output shaft 203 transmits power to the first drive mechanism 302, thereby causing the swing arm 305 to rotate 180°, and causing the wheel 03 to rotate from the second position to the first position, as shown below. Figure 7 As shown. At this time, the position of wheel 03 is higher than the chassis to avoid affecting the vehicle's driving on land.

[0081] Alternatively, wheel 03 can also be used for steering assistance when in the second position. That is, the second drive mechanism 201 drives wheel 03 to rotate downward to the second position, and then the rear wheels are lifted by the vehicle suspension system so that wheel 03 can contact the ground. At this time, the vehicle is supported by the front wheels and wheel 03, and the first drive mechanism 302 drives wheel 03 to rotate, thereby assisting in vehicle steering or parallel parking.

[0082] When the first output shaft 203 drives the swing arm 305 to rotate around the first output shaft 203, it is only necessary to adjust the spare wheel to be above the chassis to avoid affecting the vehicle's driving on land. The rotation angle of the swing arm 305 can be determined by those skilled in the art based on actual conditions, and is not specifically limited here.

[0083] When the vehicle encounters a tire blowout or damage, or when it is necessary to remove the spare wheel, the second drive mechanism 201 is activated, which drives the swing arm 305 to rotate, so that the spare wheel is adjusted to a certain angle position, thereby leaving space for removing the spare wheel. Using a disassembly tool, the wheel 03 is removed from the first input shaft 306 and the wheel 03 replaces the damaged tire.

[0084] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.
