The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0049] In the description of this utility model, "first feature" and "second feature" may include one or more of the features.

[0050] In the description of this utility model, "multiple" means two or more, and "several" means one or more.

[0051] The blade assembly 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0052] like Figures 1-11 As shown, the blade assembly 1 according to an embodiment of the present invention includes a blade body 300 and a connecting portion 100.

[0053] The connecting part 100 is used to connect the blade body 300 to the wheel 2. The blade body 300 can rotate relative to the connecting part 100 along the first axis L1, and the first axis L1 intersects the axis of the wheel 2.

[0054] The connecting part 100 can rotate relative to the wheel 2, thereby driving the blade body to unfold outward from the wheel 2 or storing the blade body 300 and attaching it to the wheel 2.

[0055] The blade body 300 can be made of plastic.

[0056] According to the embodiment of the present invention, the blade assembly 1 rotates the blade body 300 relative to the connecting portion 100 along a first axis L1, and the first axis L1 intersects the axis of the wheel 2. Thus, when the vehicle is wading through water, the blade assembly 1 rotates away from the wheel 2 to open the blade body 300. Simultaneously, the blade body 300 can rotate relative to the connecting portion 100 along the first axis L1, allowing it to adjust the stroking angle of the blade body 300. When the wheel 2 rotates, the blade body 300 can stroke more effectively; for example, the stroking area of ​​the blade body 300 can be larger to fully utilize the thrust generated by the blade body 300 stroking when the wheel 2 rotates, increasing the thrust of the vehicle in water and providing more power when wading through water.

[0057] In addition, by intersecting the first axis L1 with the axis of the wheel 2, it is not only convenient to adjust the water-sweeping angle of the blade body 300 to adjust the water-sweeping thrust of the blade body 300, making the vehicle more powerful when driving through water, but also when the blade assembly 1 is closed, by rotating the blade body 300 along the first axis L1, the blade body 300 can be better stored and hidden in the wheel 2, which is beneficial to improving the overall aesthetics of the wheel 2 and reducing the wind resistance of the blade assembly 1.

[0058] Furthermore, it is understood that by adjusting the angle of rotation of the blade body 300 of the blade assembly 1 on multiple wheels 2 around the first axis L1, the angle of the blade body 300 on multiple wheels 2 can be adjusted, that is, the angle of the thrust generated by the blade body 300 in wading can be adjusted. When the vehicle is wading and turning, while using the blade assembly 1 on the four wheels 2 to achieve wading and turning (for example, only opening the blade assembly 1 on the wheel 2 that needs to be turned and its diagonal wheel 2 located below the central axis), the thrust generated by the blade body 300 in wading can also be adjusted to assist the vehicle in turning, so that the thrust generated by the blade body 300 in wading can be biased towards the side that needs to be turned, thereby making the vehicle turn more easily.

[0059] According to the embodiment of the present invention, the blade assembly 1 has a large water-sweeping area and an adjustable water-sweeping angle, which can provide sufficient thrust when the vehicle is driving through water.

[0060] According to some embodiments of this utility model, such as Figure 9 As shown, the connecting part 100 includes a housing 110, a first drive mechanism 120, and a first transmission mechanism 130.

[0061] The first drive mechanism 120 and the first transmission mechanism 130 are located inside the housing 110, and the first drive mechanism 120 and the first transmission mechanism 130 are located at the connection between the housing 110 and the blade body 300. The first drive mechanism 120 drives the first transmission mechanism 130 to rotate, so as to realize that the blade body 300 rotates along the first axis L1 by a preset angle.

[0062] In this way, the first drive mechanism 120 and the first transmission mechanism 130 are closer to the blade body 300, which makes it easier to fix the blade body 300 to the housing 110 through the first drive mechanism 120 and the first transmission mechanism 130, so that the blade body 300 can be fixed relative to the wheel 2. Moreover, the first drive mechanism 120 and the first transmission mechanism 130 can drive the blade assembly 1 to rotate around the first axis L1 to adjust the angle of the blade assembly 1 relative to the connecting part 100, thereby adjusting the water-pushing angle of the blade assembly 1 and making the vehicle have greater thrust when driving through water.

[0063] According to some embodiments of this utility model, such as Figure 9 As shown, the connecting part 100 also includes a second transmission mechanism 140 and a second drive mechanism 150.

[0064] The second transmission mechanism 140 is located inside the housing 110. One end of the second drive mechanism 150 is connected to the second transmission mechanism 140, and the other end of the second drive mechanism 150 is adapted to be connected to the hub 500 of the wheel 2. It is used to drive the blade body 300 to rotate around the second axis L2, so that the blade body 300 is at least partially away from the wheel 2. The first axis L1 intersects the second axis L2.

[0065] The second axis L2 can be perpendicular to the axial direction of the wheel 2. When the second drive mechanism 150 drives the second transmission mechanism 140 to rotate, it can drive the blade body 300 to rotate together, so that the blade body 300 can be extended outward from the wheel 2 or the blade body 300 can be stored and attached to the wheel 2.

[0066] Therefore, when the vehicle is wading through water, the second drive mechanism 150 can drive the blade assembly 1 to rotate around the second axis L2 away from the wheel 2 through the second transmission mechanism 140, and the blade body 300 gradually opens. At the same time, the first drive mechanism 120 can drive the blade body 300 to rotate around the first axis L1 to adjust the water-striking angle of the blade body 300. In this way, the blade body 300 can be used to generate thrust by striking the water when the wheel 2 is rotating, thereby increasing the thrust of the vehicle when driving in water, so that the vehicle has more power when wading through water.

[0067] When the vehicle is driving on a normal road, the second drive mechanism 150 can drive the blade body 300 to rotate around the second axis L2 toward the wheel 2 through the second transmission mechanism 140. At the same time, the second drive mechanism 150 can drive the blade body 300 to rotate around the first axis L1 so that the blade body 300 can rotate perpendicular to the central axis of the wheel 2. At this time, the blade body 300 can fit against the wheel 2, that is, the blade body 300 can be hidden in the wheel 2, and the wind resistance of the blade body 300 itself is small.

[0068] In addition, with this configuration, when the vehicle is driving on a normal road surface, the angle of the blade body 300 can be adjusted by the first drive mechanism 120 and the second drive mechanism 150 so that the blade body 300 can cover the hollow part of the spoke 600, thereby reducing the hollow ratio of the spoke 600, further reducing the wind resistance of the wheel 2, and making the vehicle less resistant to movement, which is beneficial to improving the vehicle's economy.

[0069] Furthermore, it should be noted that the angle at which the first drive mechanism 120 drives the blade body 300 to rotate around the first axis L1, and the angle at which the second drive mechanism 150 drives the blade body 300 to rotate around the second axis L2, can both be related to the depth of the accelerator pedal. This allows the driver to control the rotation angle of the blade body 300 in two directions via the accelerator pedal, so that the driver can adjust the magnitude and direction of the thrust generated by the blade body 300 in real time.

[0070] Furthermore, such as Figure 7 and Figure 8 As shown, the first axis L1 coincides with the central axis of the blade body 300; and / or, the second axis L2 is adapted to be perpendicular to the axis of the wheel 2.

[0071] In this way, by controlling the rotation of the blade body 300 around the first axis L1, the rotation angle of the blade body 300 relative to the connecting part 100 can be adjusted so that when the blade body 300 is stored and hidden in the wheel 2, it fits against the wheel 2 to reduce wind resistance. When the blade body 300 is unfolded, the slashing angle of the blade body 300 can be adjusted to increase the slashing area of ​​the blade body 300, so that a greater thrust can be generated by slashing the water, and the vehicle has more power when driving through water.

[0072] In addition, by controlling the blade body 300 to rotate along the second axis L2, the position of the blade body 300 in the axial direction of the vehicle can be adjusted so as to rotate the blade body 300 to be stored and hidden in the wheel 2 or to extend the blade body 300 outward from the wheel 2.

[0073] In addition, it is understood that when the second drive mechanism 150 drives the second transmission mechanism 140 to rotate around the second axis L2, the second transmission mechanism 140 can drive the blade body 300 to rotate together around the second axis L2, that is, the blade body 300 can revolve around the second axis L2.

[0074] Therefore, the second drive mechanism 150 and the first drive mechanism 120 can drive the blade body 300 to rotate in different directions independently. Specifically, the first drive mechanism 120 can drive the blade body 300 to rotate around the first axis L1 independently, and the second drive mechanism 150 can drive the blade body 300 to rotate around the second axis L2 independently. The rotation angle adjustment of the blade body 300 in the two directions can be independent of each other, and the drive structure is simpler.

[0075] Of course, in some embodiments, the first drive mechanism 120 and the second drive mechanism 150 can also be associated, that is, the second drive mechanism 150 can be connected to the first drive mechanism 120 in a transmission manner, so that the first drive mechanism 120 and the second drive mechanism 150 can operate synchronously, so that the angle adjustment of the blade body 300 in two directions can be carried out synchronously, and the synchronization is higher.

[0076] According to some embodiments of this utility model, such as Figure 9 and Figure 11 As shown, the second transmission mechanism 140 includes a protective housing 141.

[0077] The housing 110 is rotatably mounted on the hub 500, the protective shell 141 is fixed inside the housing 110, and the inner circumferential surface of the protective shell 141 is constructed with meshing teeth 142. The second drive mechanism 150 has an output gear 151, and the meshing teeth 142 mesh with the output gear 151.

[0078] The second axis L2 can be the central axis of the output gear 151.

[0079] In this way, the protective shell 141 can rotate synchronously with the housing 110. When the second drive mechanism 150 is running, the power can be transmitted to the meshing teeth 142 of the protective shell 141 through the output gear 151 of the second drive mechanism 150. Then, the second drive mechanism 150 can drive the second transmission mechanism 140 to rotate around the second axis L2. Thus, the blade assembly 1 can be driven to rotate around the second axis L2 through the second transmission mechanism 140 and the housing 110.

[0080] It is understandable that by separating the housing 110 and the protective shell 141 and then installing and fixing the protective shell 141 inside the housing 110, it is convenient to machine the meshing teeth 142 inside the protective shell 141, thereby simplifying the manufacturing of the transmission components. Of course, in some embodiments, the meshing teeth 142 can also be machined directly inside the housing 110, that is, the housing 110 and the protective shell 141 are a single piece, which can reduce the number of parts in the connecting part 100 and facilitate assembly.

[0081] According to some embodiments of this utility model, such as Figure 9 As shown, there are multiple second drive mechanisms 150, which are located on opposite sides of the housing 110. There are multiple meshing teeth 142, which mesh with the output gears 151 of the multiple second drive mechanisms 150 in a one-to-one correspondence.

[0082] Among them, multiple second drive mechanisms 150 can be located on opposite sides of the protective shell 141 along the axial direction.

[0083] In this way, multiple second drive mechanisms 150 can synchronously drive the second transmission mechanism 140 to rotate around the second axis L2. The driving force of the multiple second drive mechanisms 150 is more sufficient and the drive is more reliable. Moreover, by placing the multiple second drive mechanisms 150 on opposite sides of the housing 110, that is, by inputting power from opposite sides of the axial direction of the housing 110, the driving force of the multiple second drive mechanisms 150 can be more balanced, thereby driving the second transmission mechanism 140 and the housing 110 to rotate more smoothly.

[0084] According to some embodiments of this utility model, such as Figure 4 , Figures 7-9 As shown, a first positioning part 310 is provided at one end of the blade body 300 away from the connecting part 100. The first positioning part 310 is used to cooperate with the second positioning part 410 of the rim 400 to achieve relative positioning and fixation of the blade body 300 and the rim 400.

[0085] By setting the second positioning part 410 and the first positioning part 310 to cooperate, when the blade assembly 1 is stored and hidden in the wheel 2, the end of the blade body 300 away from the hub 500 can be engaged with the second positioning part 410 through the first positioning part 310, thereby preventing the blade body 300 from shaking and fixing the blade body 300 more stably to the rim 400. Moreover, with this setting, the end of the blade body 300 away from the connecting part 100 can fit more tightly with the rim 400, which helps to reduce the wind resistance of the wheel 2 when the vehicle is driving on a normal road.

[0086] Furthermore, such as Figure 4As shown, the first positioning part 310 can be configured as a positioning protrusion, and the second positioning part 410 can be configured as a positioning groove. Furthermore, the bottom wall of the positioning groove can be configured as an inclined surface, and the end face of the positioning protrusion facing the positioning groove can also be configured as an inclined surface. This not only allows the positioning protrusion to fit tightly with the positioning groove, but also ensures that the positioning protrusion will not interfere with the rim 400 when the blade body 300 rotates away from the wheel 2, so as to facilitate the separation of the end of the blade body 300 away from the hub 500 from the rim 400.

[0087] The wheel 2 according to an embodiment of the present invention is described below with reference to the accompanying drawings, such as... Figures 1-6 and Figure 10 As shown, the wheel 2 includes a rim 400, a hub 500, spokes 600, and a blade assembly 1 according to the above embodiment of the present invention.

[0088] The hub 500 is connected to the spokes 600, and the hub 500 is provided with a rotating groove 510. The spokes 600 are connected to the rim 400 and the hub 500 respectively. The connecting part 100 of the blade assembly 1 is rotatably connected to the rotating groove 510.

[0089] Specifically, the second drive mechanism 150 of the connecting part 100 can be fixed in the rotating groove 510, and the housing 110 can rotate relative to the rotating groove 510 so that the blade body 300 can rotate relative to the hub 500.

[0090] The rotating groove 510 may have first mounting holes 513 on its two opposite side walls in the width direction, and the second drive mechanism 150 of the blade assembly 1 may be installed in the first mounting holes 513.

[0091] According to the embodiment of the present invention, the wheel 2 utilizes the blade assembly 1 according to the above embodiment of the present invention. The blade body 300 has a large water-sweeping area and an adjustable water-sweeping angle, which can provide sufficient thrust when the vehicle is driving through water.

[0092] In some specific embodiments of this utility model, such as Figure 10 As shown, the hub 500 is hemispherical, and the rotating groove 510 extends along the spherical surface of the hub 500. That is, the projection of the rotating groove 510 onto a plane perpendicular to the width direction of the rotating groove 510 can be fan-shaped.

[0093] Thus, when the second drive mechanism 150 drives the second transmission mechanism 140 to rotate, that is, when the connecting part 100 drives the blade body 300 to rotate away from or towards the wheel 2, the housing 110 of the connecting part 100 can rotate along the rotating groove 510, thereby opening the blade body 300 or storing and hiding the blade body 300 in the wheel 2. Furthermore, during the process of the second transmission mechanism 140 driving the housing 110 to rotate, the housing 110 will not interfere with the side wall of the rotating groove 510, making rotation more convenient.

[0094] Furthermore, the opposite side walls of the rotating groove 510 in the width direction can limit the housing 110, thereby preventing the connecting part 100 from shaking in the width direction of the rotating groove 510, that is, preventing the blade body 300 from shaking in the width direction of the rotating groove 510, and making the rotation of the blade body 300 around the second axis L2 more stable.

[0095] Furthermore, such as Figure 10 As shown, there are multiple rotating slots 510, which are arranged at intervals along the circumference of the hub 500. There are multiple blade assemblies 1, which are installed in the rotating slots 510 one by one.

[0096] For example, there can be six rotating slots 510, which are evenly distributed on the hub 500. There can also be six blade assemblies 1, which are installed in the six rotating slots 510 one by one. Of course, the number of rotating slots 510 and the number of blade assemblies 1 are not limited to six. This is just an example and is not a limitation.

[0097] With this configuration, multiple blade assemblies 1 can be installed on each wheel 2. When the vehicle is driving through water, some of the multiple blade assemblies 1 can unfold and propel the water to generate thrust. With a large number of blade assemblies 1, the thrust generated by the blade body 300 propels the water can be greater, thereby improving the forward power of the vehicle when driving through water and making the vehicle more powerful when driving through water.

[0098] In some specific embodiments of this utility model, such as Figure 10 As shown, the hub 500 may be provided with a second mounting hole 520. The second mounting hole 520 passes through the hub 500 along the axial direction of the wheel 2, so that the wheel 2 and the brake disc can be connected and fixed by using mounting bolts passing through the second mounting hole 520 and the rim 400.

[0099] In addition, the second mounting holes 520 and the rotating grooves 510 can be arranged at intervals along the circumference of the hub 500. For example, there can be multiple second mounting holes 520, and multiple second mounting holes 520 and multiple rotating grooves 510 can be arranged alternately along the circumference of the hub 500. In this way, the multiple second mounting holes 520 and multiple rotating grooves 510 are more evenly distributed in the circumference of the hub 500. The multiple second mounting holes 520 and multiple rotating grooves 510 will not interfere with each other in position, which is beneficial to ensuring the structural strength of the hub 500. Moreover, it can avoid interference between the assembly of the blade assembly 1 and the hub 500 and the assembly of the wheel 2 and the brake disc, which is convenient for assembly.

[0100] In some specific embodiments of this utility model, such as Figure 10 As shown, the rotating groove 510 has a first sidewall 511 and a second sidewall 512, and the first sidewall 511 is perpendicular to the second sidewall 512.

[0101] Therefore, when the blade assembly 1 rotates in the rotating groove 510, the blade assembly 1 rotates from the first side wall 511 to the second side wall 512. The rotation angle of the blade assembly 1 can be 90°, that is, the maximum rotation angle of the blade assembly 1 around the first axis L1 can be 90°. The rotation range of the blade assembly 1 is large, which can ensure that the rotation angle of the blade body 300 in the direction away from the wheel 2 can be large, so that the blade body 300 can be fully unfolded in the direction away from the wheel 2. This can ensure that the swash area of ​​the blade body 300 is large, and the thrust generated by the swash is greater and more sufficient.

[0102] In some specific embodiments of this utility model, the blade assembly 1 has a first limit position and a second limit position.

[0103] When the blade assembly 1 is in the first extreme position, the blade assembly 1 stops against the first side wall 511, and the central axis of the blade body 300 is parallel to the radial direction of the wheel 2. Thus, when the blade assembly 1 is in the first extreme position, the blade body 300 can be rotated by the first drive mechanism 120 so that the plane of the blade body 300 is parallel to the radial direction of the wheel 2. This allows the blade body 300 to be better housed and hidden in the wheel 2, improving the aesthetics of the wheel 2. At the same time, it can reduce the wind resistance of the blade body 300, so that the wind resistance of the wheel 2 is smaller when the vehicle is driving on a normal road.

[0104] When the blade assembly 1 is in the second limit position, the blade assembly 1 stops against the second side wall 512, and the central axis of the blade body 300 is parallel to the axial direction of the wheel 2. In this way, when the blade assembly 1 rotates to the second limit position, the blade body 300 can be maximized and the water-sweeping area of ​​the blade body 300 can be maximized, thereby increasing the thrust generated by the blade body 300 in water-sweeping. The blade body 300 can provide more assistance when the vehicle is wading through water, and the vehicle has more power when wading through water.

[0105] In addition, it should be noted that the blade assembly 1 can not only rotate to the first limit position and the second limit position, but also rotate to any position between the first limit position and the second limit position and hover. This makes the opening degree of the blade assembly 1 more adjustable. The specific opening angle can be adjusted according to the power required when wading. For example, the stopping position of the blade assembly 1 in the rotating groove 510 can be controlled according to the depth of the accelerator pedal, so as to adjust the water-sweeping area of ​​the blade body 300 according to the depth of the accelerator pedal.

[0106] In some specific embodiments of this utility model, such as Figures 1-4 As shown, the spokes 600 are provided with a plurality of spokes 610, and a receiving gap 611 is formed between two adjacent spokes 610. The blade assembly 1 is at least partially located in the receiving gap 611 to cover the receiving gap 611.

[0107] In other words, when projected onto a plane perpendicular to the axial direction of the wheel 2, at least a portion of the projection of the blade body 300 overlaps with the projection of the receiving gap 611, thereby allowing the blade body 300 to cover the receiving gap 611.

[0108] It is understood that the greater the openness of the wheel 2, the greater the wind resistance. Therefore, when the vehicle is driving on land, the blade assembly 1 can be switched to the first extreme position, and the blade body 300 and the wheel 2 are on the same plane (that is, the plane where the blade body 300 is located is perpendicular to the axis of the wheel 2). In this way, the blade body 300 can be used to cover the gap 611 to reduce the open area of ​​the spoke 600. The air resistance of the wheel 2 when it rotates can be smaller, thereby reducing the wind resistance of the vehicle and helping to reduce the energy consumption of the vehicle and improve the driving economy of the vehicle.

[0109] In some specific embodiments of this utility model, such as Figures 1-4 As shown, the blade assembly 1 and the spokes 600 are staggered along the axial direction of the wheel 2.

[0110] Specifically, along the axial direction of the wheel 2, the blade assembly 1 can be located on the outer side of the rim 400. This can prevent the blade assembly 1 and the rim 400 from interfering with each other in the axial direction of the wheel 2, so that the blade assembly 1 can be stored and hidden in the wheel 2 when the vehicle is driving on a normal road surface.

[0111] The following description, with reference to the accompanying drawings, describes a vehicle according to an embodiment of the present invention, the vehicle including wheels 2 according to the above embodiment of the present invention.

[0112] According to the vehicle of the present invention, by utilizing the wheel 2 of the above embodiment of the present invention, the blade body 300 of the blade assembly 1 has a large water-sweeping area and an adjustable water-sweeping angle, which can provide sufficient thrust when the vehicle is driving through water.

[0113] It should be noted that when the vehicle is driving through water and the wheels 2 are floating on the water without contact with the ground, there may be two situations: one is that the water depth is lower than the central axis of the wheels 2, and the other is that the water depth is higher than the central axis of the wheels 2.

[0114] When the water depth is below the central axis of wheel 2, the blade assembly 1 below the central axis of wheel 2 can be in the open state, meaning the blade assembly 1 rotates outward from wheel 2, while the blade assembly 1 above the central axis of wheel 2 can be in the closed state, meaning the blade body 300 is fitted and hidden within wheel 2. Specifically, the state of multiple blade assemblies 1 can be adjusted in real time. When a blade assembly 1 rotates below the central axis of wheel 2, the blade body 300 is opened; when a blade assembly 1 rotates above the central axis of wheel 2, the blade body 300 is closed. This ensures that the blade body 300 rotating underwater can generate thrust by paddling, while the blade body 300 rotating above the water can be closed to reduce wind resistance. Alternatively, to simplify the control of multiple blade assemblies 1, the open blade body 300 can remain open, while the closed blade body 300 remains closed. When the open blade body 300 rotates underwater, it can provide thrust for the vehicle to move forward by paddling.

[0115] When the water depth is higher than the central axis of wheel 2, wheel 2 is completely submerged. Understandably, during wheel 2 rotation, the blades 300 below the central axis of wheel 2 generate thrust by swishing through the water, while the blades above the central axis generate resistance, hindering the vehicle's movement in water. Therefore, when the water depth is higher than the central axis of wheel 2, the states of multiple blade assemblies 1 must be adjusted in real time. When blade assembly 1 rotates below the central axis of wheel 2, the blades 300 are opened; when blade assembly 1 rotates above the central axis of wheel 2, the blades 300 are closed. This ensures that only the blade assemblies 1 located below the central axis of wheel 2 can open and generate thrust to propel the vehicle forward, thus providing sufficient forward momentum when the vehicle is wading through deeper water.

[0116] The water level can be detected by setting a water level sensor inside the wheel hub 500. In addition, multiple position sensors can be set on the wheel 2 and the position of multiple blade assemblies 1 relative to the central axis of the wheel 2 can be obtained by the position sensors. This allows the detection that the corresponding blade assembly 1 is above or below the central axis of the wheel 2, so as to enable real-time control of multiple blade assemblies 1.
