[0019] Optionally, it may also include a second drive mechanism adapted to drive the drive component to rotate.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] According to one embodiment of this application, a driving component is provided. For example... Figures 1 to 6 As shown, the drive assembly includes a propulsion mechanism 04 and a first drive mechanism 06. The propulsion mechanism 04 is adapted to provide propulsion force. The first drive member 401 is drively connected to the propulsion mechanism 04. The first drive mechanism 06 can drive the propulsion mechanism 04 to rotate upwards while simultaneously rotating to the left or right, or drive the propulsion mechanism 04 to rotate downwards while simultaneously rotating to the left or right.

[0043] In this example, the first drive mechanism 06 is connected to the propulsion mechanism 04. The first drive mechanism 06 can drive the propulsion mechanism 04 to rotate upward while rotating to the left or right, or drive the propulsion mechanism 04 to rotate downward while rotating to the left or right, thereby adjusting the angle of the propulsion mechanism 04 to adjust the propulsion direction of the propulsion mechanism 04, thus improving the controllability and flexibility of the drive component.

[0044] like Figure 3 As shown, in this example, the propulsion mechanism 04 includes a propeller structure 402 that rotates to provide thrust. A first drive mechanism 06 is driven to the propulsion mechanism 04 and can drive the propulsion mechanism 04 to rotate, thereby driving the propeller structure 402 to rotate clockwise or counterclockwise.

[0045] Alternatively, in this example, the first driving member 401 is connected to the propulsion mechanism 04 and can drive the propulsion mechanism 04 to rotate clockwise or counterclockwise.

[0046] In one example, the first drive mechanism 06 includes a first output shaft 605 and a swing arm 604. One end of the swing arm 604 is connected to the first output shaft 605, and the other end is connected to the propulsion mechanism 04. The first output shaft 605 can drive the swing arm 604 to rotate, thereby driving the propulsion mechanism 04 to rotate.

[0047] In this example, the first drive mechanism 06 includes a first output shaft 605 and a swing arm 604. One end of the swing arm 604 is connected to the first output shaft 605, and the other end is rotatably connected to the propulsion mechanism 04. The first output shaft 605 can drive the swing arm 604 to rotate, thereby driving the propulsion mechanism 04 to rotate.

[0048] In this example, the first output shaft 605 can be set perpendicular to the swing arm 604. The first output shaft 605 drives the swing arm 604 to rotate, thereby driving the propulsion mechanism 04 to rotate.

[0049] In one example, the drive component also includes a mounting mechanism 05, to which the propulsion mechanism 04 is movably connected.

[0050] In this example, the propulsion mechanism 04 is rotatably connected to the mounting mechanism 05, and the first drive mechanism 06 can drive the propulsion mechanism 04 to rotate relative to the mounting mechanism 05. For example, the propulsion mechanism 04 includes a first drive member 401, and the propeller structure 402 is drivenly connected to the first drive member 401. The middle part of the first drive member 401 is movably connected to the mounting mechanism 05. The end of the first drive member 401 away from the propeller structure 402 is rotatably connected to the swing arm 604. The first output shaft 605 is fixedly connected to the swing arm 604, and the first output shaft 605 drives the swing arm 604 to rotate, thereby driving the first drive member 401 to rotate relative to the mounting mechanism 05. That is, the swing arm 604 drives the end of the first drive member 401 away from the propeller structure 402 to rotate counterclockwise, so that the propeller structure 402 can rotate clockwise; or, the swing arm 604 drives the end of the first drive member 401 away from the propeller structure 402 to rotate clockwise, so that the propeller structure 402 can rotate counterclockwise.

[0051] In this example, such as Figure 2 As shown, the drive assembly can be installed on an amphibious vehicle. When the vehicle is moving in water, the propulsion mechanism 04 provides the thrust that propels the vehicle forward. The propulsion mechanism 04 is rotatably connected to the mounting mechanism 05. The first output shaft 605 is driven to the propulsion mechanism 04 via a swing arm 604. The first output shaft 605 can drive the swing arm 604 to rotate, thereby causing the swing arm 604 to swing the propulsion mechanism 04 relative to the mounting mechanism 05. This allows the propulsion mechanism 04 to swing to a suitable angle, thus enabling the vehicle's direction of travel to be changed as needed, such as for turning or U-turns, improving the vehicle's flexibility and maneuverability in water.

[0052] In this example, such as Figure 3As shown, the propulsion mechanism 04 includes a propeller structure 402, which provides forward thrust through rotation. By oscillating the propulsion mechanism 04, the angle of the propeller structure 402 can be adjusted, thereby regulating the direction of the thrust provided by the propeller structure 402. Alternatively, the propulsion mechanism 04 can be a jet propulsion device; by oscillating the propulsion mechanism 04, the angle of the jet propulsion device can be adjusted, changing the jet direction, thereby regulating the direction of the thrust provided by the jet propulsion device. Of course, the specific structure of the propulsion mechanism 04 can be determined by those skilled in the art according to actual conditions, and is not specifically limited here.

[0053] In one example, such as Figures 3 to 6 As shown, the mounting mechanism 05 includes a first mounting member 501 and a second mounting member 502. The first mounting member 501 is rotatably connected to the second mounting member 502 along a first axis, and the pushing mechanism 04 is rotatably connected to the first mounting member 501 along a second axis. The first axis is vertically arranged, and the second axis is horizontally arranged.

[0054] like Figure 3 and Figure 4 As shown, the first mounting member 501 is rotatably mounted on the second mounting member 502 and can rotate about a first axis. The propulsion mechanism 04 is rotatably mounted on the first mounting member 501 and can rotate about a second axis. The first axis is perpendicular to the second axis. The middle part of the propulsion mechanism 04 is connected to the first mounting member 501, and a swing arm 604 is connected to one end of the propulsion mechanism 04. The other end of the propulsion mechanism 04 has a power end. Rotation of the swing arm 604 drives the propulsion mechanism 04 to rotate relative to the first mounting member 501. The first mounting member 501 can rotate relative to the second mounting member 502, allowing for up / down and left / right deflection of the propulsion angle of the power end, thereby adjusting the power end to a suitable angle.

[0055] For example, the propulsion mechanism 04 includes a propeller structure 402, which is driven to rotate by a first driving member 401. That is, the propeller structure 402 is the power end of the propulsion mechanism 04, and the swing arm 604 is connected to the end of the first driving member 401 that is away from the propeller structure 402. The first driving member 401 is rotatably mounted on the first mounting member 501 around a second axis.

[0056] In one example, such as Figure 3 As shown, the propulsion mechanism 04 includes a first drive member 401, which is adapted to output power, and a first mounting member 501 is rotatably connected to at least one side of the first drive member 401 in the radial direction.

[0057] like Figure 3The first driving member 401 is adapted to output power. For example, the output end of the first driving member 401 is connected to the propeller structure 402, and is adapted to drive the propeller structure 402 to rotate. The first mounting member 501 is rotatably connected to at least one side of the first driving member 401 in the radial direction. The first driving member 401 can rotate to adjust the angle of the propeller structure 402. The first driving member 401 can be a drive motor, or it can be other rotary drive structures capable of driving the propeller structure 402 to rotate. Those skilled in the art can determine this according to the actual situation, and no specific limitation is made here.

[0058] like Figure 3 and Figure 5 As shown, in this example, the first driving member 401 has first connecting posts 404 on both radial sides, and the first connecting posts 404 are rotatably connected to the first mounting member 501. The first driving member 401 has first connecting posts 404 on both radial sides, that is, the first connecting posts 404 are arranged along the second axis. The presence of first connecting posts 404 on both sides of the first driving member 401 improves the stability of the connection.

[0059] like Figure 6 As shown, the first mounting component 501 has corresponding connecting holes on its two opposite sides, and the two first connecting posts 404 can be inserted into the connecting holes respectively and can rotate within the connecting holes.

[0060] Alternatively, the first connecting post 404 can also be disposed on the first mounting member 501, and the first driving member 401 can be provided with a corresponding connecting hole. Those skilled in the art can decide according to the actual situation, and no specific limitation is made here.

[0061] In one example, such as Figure 5 As shown, the propulsion mechanism 04 also includes a propeller structure 402, and the first driving member 401 is connected to the propeller structure 402. The first driving member 401 and the propeller structure 402 are coaxially arranged.

[0062] like Figure 5 As shown, in this example, the first drive member 401 can drive the propeller structure 402 to rotate, thereby providing thrust in the water. The first drive member 401 is coaxially arranged with the propeller structure 402, which allows for a more compact structure of the propulsion mechanism 04.

[0063] like Figure 5 and Figure 6As shown, the output end of the first driving member 401 is connected to the propeller structure 402. The other end of the first driving member 401, away from the propeller structure 402, is provided with a first input shaft 405, which is rotatably connected to one end of the swing arm 604. The end of the swing arm 604 away from the first input shaft 405 is fixedly connected to the first output shaft 605. The swing arm 604 and the first output shaft 605 have an angle, which is not equal to 0° or 180°. That is, the swing arm 604 and the first output shaft 605 are neither parallel nor coincident, so that the first output shaft 605 and the first input shaft 405 are not coaxially arranged, and the rotation of the swing arm 604 can drive the first driving member 401 to swing.

[0064] like Figure 5 As shown, in this example, a flow guide 403 is also provided on the outside of the propeller structure 402. The flow guide 403 can guide the water flow to flow more smoothly through the propeller structure 402, reduce the vortex loss behind the propeller, and enable the propeller structure 402 to better utilize the power of the water flow, thereby improving the efficiency of the propeller structure 402.

[0065] In one example, such as Figure 6 As shown, the first mounting component 501 is provided with a second connecting post 503, which is rotatably connected to the second mounting component 502.

[0066] The second connecting post 503 is disposed along the first axis, and the second mounting member 502 is correspondingly provided with a connecting hole, into which the second connecting post 503 is inserted. Alternatively, the second mounting member 502 is disposed with the second connecting post 503 along the first axis, and the first mounting member 501 is correspondingly provided with a connecting hole. Those skilled in the art can determine the specific arrangement according to the actual situation, and no specific limitation is made here.

[0067] like Figure 3 and Figure 6 As shown, in this example, the first mounting member 501 has four side edges, which are connected end to end. Two opposite side edges are rotatably connected to the first driving member 401, and the other two opposite side edges are rotatably connected to the second mounting member 502. The first driving member 401 can pass through the first mounting member 501 and is rotatably connected to the two opposite side edges of the first mounting member 501.

[0068] In one example, such as Figure 4 and Figure 6 As shown, the first drive mechanism 06 includes a second drive member 603, the second drive member 603 is provided with the first output shaft 605, and the second drive member 603 is mounted on the second mounting member 502.

[0069] like Figure 4 and Figure 6As shown, in this example, the second drive member 603 is provided with a first output shaft 605, which drives the swing arm 604 to rotate. The second drive member 603 is mounted on the second mounting member 502 to make the overall structure more compact.

[0070] like Figure 6 As shown, in this example, the second mounting member 502 has a three-frame structure, with the two ends of the first frame connected to the second and third frames respectively along its length. The first mounting member 501 is located between the second and third frames, and its opposite ends are rotatably connected to the second and third frames respectively. The second driving member 603 is mounted on the side of the first frame facing the first mounting member 501.

[0071] For example, the second driving component 603 can be fixedly connected to the first frame by welding, snap-fitting, or screwing. Those skilled in the art can determine the appropriate method based on the specific circumstances, and no specific limitations are made here.

[0072] In this example, the second driving element 603 can be a drive motor, or it can be any other rotary drive structure capable of rotating the swing arm 604. Those skilled in the art can determine the appropriate method based on the specific circumstances, and no specific limitations are made here.

[0073] In one example, such as Figure 6 As shown, along the axial direction of the first output shaft 605, from one end of the swing arm 604 to the other end, the swing arm 604 is gradually moved away from the first output shaft 605.

[0074] like Figure 6 As shown, one end of the swing arm 604 is fixedly connected to the first output shaft 605, and the other end is rotatably connected to the propulsion mechanism 04. From one end to the other, the swing arm 604 gradually moves away from the first output shaft 605; that is, the swing arm 604 can be tilted or bent, which can prevent interference between the propulsion mechanism 04 and the second drive member 603 when the latter swings. Furthermore, the tilted or bent configuration of the swing arm 604 increases the installation space when the swing arm 604 is connected to the first output shaft 605 or the propulsion mechanism 04 is connected to the swing arm 604, facilitating installation.

[0075] According to another embodiment of this application, a driving device is provided, which includes the driving component of the above embodiment. The driving component includes a propulsion mechanism 04 and a first driving mechanism 06. The first driving mechanism 06 is tractively connected to the propulsion mechanism 04. The first driving mechanism 06 can drive the propulsion mechanism 04 to rotate upwards while simultaneously rotating to the left or right, or drive the propulsion mechanism 04 to rotate downwards while simultaneously rotating to the left or right, thereby adjusting the angle of the propulsion mechanism 04 to adjust its propulsion direction, improving the controllability and flexibility of the driving component.

[0076] In one example, such as Figure 1 , Figure 2 and Figure 7 As shown, the drive assembly also includes a second drive mechanism 03, which is adapted to rotate the propulsion mechanism 04. The second drive mechanism 03 can rotate the propulsion mechanism 04 to adjust it to a suitable position.

[0077] like Figure 1 and Figure 2 As shown, the drive assembly is mounted on the rear door 01 of the vehicle, and the second drive mechanism 03 is mounted on the rear door 01. The output end of the second drive mechanism 03 can drive the propulsion mechanism 04 to rotate. For example, as... Figure 1 As shown, when the vehicle is driving on land, the second drive mechanism 03 flips the propulsion mechanism 04 upwards. A spare tire 02 is also installed on the rear door 01. The propulsion mechanism 04 can be partially embedded in the hollow position of the spare tire 02 to protect the propulsion mechanism 04. Figure 2 As shown, when the vehicle is traveling in water, the second drive mechanism 03 can flip the propulsion mechanism 04 downward so that the propulsion mechanism 04 can be submerged in water, providing the vehicle with propulsion to move forward in the water.

[0078] In one example, such as Figure 7 As shown, the second drive mechanism 03 is provided with a support arm 301, which is connected to the mounting mechanism 05. The support arm 301 can drive the mounting mechanism 05 to rotate, thereby driving the propulsion mechanism 04 to rotate.

[0079] like Figure 7 As shown, in this example, the second drive mechanism 03 includes a support arm 301, which is connected to the second mounting member 502 of the mounting structure. For example, the support arm 301 is fixedly screwed onto the first frame of the second mounting member 502.

[0080] In this example, the support arm 301 can be connected to the mounting mechanism 05 by means of screwing, welding or snap-fitting, etc. Those skilled in the art can decide according to the actual situation, and no specific limitation is made here.

[0081] like Figure 7 As shown, in this example, the second drive structure also includes a mounting bracket 302 and a third drive member 303. The mounting bracket 302 can be used to connect to the rear door 01 of the vehicle. The third drive member 303 is mounted on the mounting bracket 302 and is drively connected to the support arm 301, enabling the support arm 301 to swing.

[0082] In this example, the third driving component 303 can be a drive motor, or it can be any other rotary drive structure capable of rotating the support arm 301. Those skilled in the art can determine the appropriate method based on the specific circumstances, and no specific limitations are made here.

[0083] In one example, such as Figure 1 , Figure 2 and Figure 7 As shown, the second drive mechanism 03 is provided in two sets, and the two sets of the second drive mechanism 03 are respectively connected to the mounting mechanism 05.

[0084] In this example, there are two sets of second drive mechanisms 03, which are respectively located on both sides of the mounting mechanism 05, thereby improving the stability of the connection of the mounting mechanism 05.

[0085] According to another embodiment of this application, a vehicle is provided. The vehicle includes the drive device described in the above embodiment. The vehicle is an amphibious vehicle, and the drive device includes a drive assembly and a second drive mechanism 03 connected to the drive assembly. The drive assembly includes a propulsion mechanism 04, a mounting mechanism 05, and a first drive mechanism 06. The propulsion mechanism 04 is adapted to provide propulsion force. The propulsion mechanism 04 is rotatably connected to the mounting mechanism 05. One end of a swing arm 604 is connected to a first output shaft 605, and the other end is rotatably connected to the propulsion mechanism 04. The first output shaft 605 can drive the swing arm 604 to rotate, thereby causing the propulsion mechanism 04 to swing relative to the mounting mechanism 05, thus adjusting the angle of the propulsion mechanism 04 to adjust its propulsion direction, improving the controllability and flexibility of the drive assembly, and thus improving the flexibility of vehicle control when in water.

[0086] In one example, the vehicle has a rear door 01, and the drive unit is mounted on the rear door 01. The vehicle also includes a spare tire 02, which is mounted on the rear door 01. The spare tire 02 has a cavity in its center, and the drive assembly can be at least partially embedded in the cavity.

[0087] like Figure 1As shown, the hollow space in the middle of the spare tire 02 houses part of the drive assembly, saving space while protecting the propulsion system. For example, the drive assembly includes a propeller structure 402, which can be embedded in the hollow space in the middle of the spare tire 02 to avoid collisions that could damage the propeller blades.

[0088] In this example, the propeller structure 402 can also be integrally formed with the spare tire 02, that is, the spokes of the spare tire 02 can be set as the propeller structure 402. The first drive member 401 can drive the spare tire 02 to rotate around the central axis.

[0089] In one example, when the vehicle experiences a tire blowout or damage, or when the spare tire 02 needs to be removed, the second drive mechanism 03 is activated, and the support arm 301 swings, causing the propulsion mechanism 04 to adjust to a certain angle. The propulsion mechanism 04 can detach from the spare tire 02, leaving space for the removal or installation of the spare tire 02.

[0090] When the vehicle enters a river or lake, the driver inputs a command to switch to water propulsion mode. At this time, the second drive mechanism 03 causes the drive assembly to tilt downwards, submerging it in the water. The propulsion mechanism 04 then generates thrust, propelling the vehicle normally through the water.

[0091] The propulsion angle can be flexibly adjusted according to actual water driving needs. When the vehicle is driving on the water and needs to turn left or right or make a U-turn, the input control command controls the first drive mechanism 06 to operate, which drives the propulsion mechanism 04 to swing. The deflection angle is determined according to the driver's intention, meeting the needs of water driving such as sharp turns and U-turns.

[0092] When the vehicle load is light, the weight of the front end accounts for a large proportion of the total vehicle mass, and the center of gravity is biased towards the front. This may cause the vehicle to nose-dive when floating in water, and also creates significant resistance during driving. Control commands can be input to activate the third drive mechanism, causing the propulsion mechanism 04 to deflect upwards. This decomposes some of the thrust of the propulsion mechanism 04 into a downward thrust, which can help alleviate the nose-diving problem.

[0093] Alternatively, when the trunk is heavily loaded, the vehicle's center of gravity shifts towards the rear, potentially causing the vehicle to nose-up when driving in water. Similarly, a control command can be input to activate the third drive mechanism, causing the propulsion mechanism 04 to deflect downwards, thus dispersing some of its thrust into an upward force to mitigate the nose-up problem.

[0094] Of course, the vehicle described in this application also includes at least all the beneficial effects of the above embodiments, which will not be repeated here.

[0095] 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.

[0096] While specific embodiments of the invention have been described in detail by way of examples, those skilled in the art should understand that the examples are for illustrative purposes only and not intended to limit the scope of the invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the invention. The scope of the invention is defined by the appended claims.
