Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a rowing device, a battery pack and a vehicle. Background Art

[0002] With the rapid development of electric vehicle technology, the situations encountered by cars during travel are becoming more and more diverse, and the functions of cars are becoming more and more diversified.

[0003] During travel, the vehicle may encounter unexpected wading. Since the vehicle cannot move normally in the water, it will pose a serious threat to the life safety of the driver and passengers in the vehicle. Summary of the invention

[0004] The purpose of the present application is to provide a rowing device, a battery pack and a vehicle, aiming to solve the problem of how to deal with vehicle wading.

[0005] In order to achieve the above object, the present invention adopts the following technical scheme:

[0006] In a first aspect, the present application provides a rowing device suitable for rowing in water, which may include a fixed part, a movable part and a rowing member, wherein the movable part is connected between the fixed part and the rowing member, and the movable part is suitable for adjusting the distance between the rowing member and the fixed part.

[0007] The rowing member can be used to provide power to move the fixed member in the water, thereby getting out of the wading dilemma. The movable member is suitable for adjusting the distance between the rowing member and the fixed member, so that the movable member can make the rowing member close to or away from the fixed member. When the rowing device is not in use, the movable member can adjust the rowing member to be close to the fixed member, so that the rowing member is not easily exposed to the field of vision, thereby improving the flatness and beauty of the fixed member; when wading or other times when the rowing device is needed, the movable member can adjust the rowing member to be away from the fixed member, leaving a working space for the rowing member, and driving the fixed member to move.

[0008] In some embodiments, the rowing member is rotatably connected to the movable member. In this way, the rowing device can generate a thrust on the water through the rotation of the rowing member, and the water can generate a reaction force on the rowing member, thereby driving the fixed member to move.

[0009] In some embodiments, the rowing member may include a paddle board and a rotating shaft connected to the paddle board, and the rotating shaft is rotatably connected to one end of the movable member so that the paddle board rotates relative to the movable member.

[0010] Since the shaft is rotatably connected to one end of the movable member, the paddle board is connected to the shaft, and the paddle board can rotate around the central axis of the shaft, so that the paddle board can rotate relative to the movable member, thereby driving the fixed member to move.

[0011] In some embodiments, when the movable member adjusts the distance between the marking member and the fixed member, the marking member has at least a first position. When the marking member is located at the first position, an extended space is formed between the fixed member and the marking member for the marking member to rotate.

[0012] When the rowing member is in the first position, an extended space is formed between the fixing member and the rowing member for the rowing member to rotate. Since the extended space is required for the rowing member to rotate, the distance between the rowing member and the fixing member is greater than or equal to the distance from the central axis of the rotating shaft to the edge of the paddle board. In this way, the fixing member will not interfere with the paddle board, so that the paddle board can rotate around the central axis of the rotating shaft.

[0013] In some embodiments, when the movable member adjusts the distance between the rowing member and the fixed member, the rowing member further has a second position, and when the rowing member is in the second position, the fixed member fits with the rowing member.

[0014] In this way, when the rowing member is in the second position, the distance between the rowing member and the fixing member is the shortest, so that when the rowing member is not used to generate power, the rowing member can be on the surface of the fixing member to ensure the overall beauty.

[0015] In some embodiments, the fixing member is provided with a receiving groove, and when the rowing member is in the second position, the rowing member is received in the receiving groove.

[0016] In this way, when the marking member is in the second position, the marking member is accommodated in the accommodating groove, which can make the surface of the marking device smoother and more beautiful, and avoid the marking member protruding from the surface of the fixing member when not in use, causing scratches or affecting the normal driving of the vehicle.

[0017] In some embodiments, the movable member may include a telescopic rod, at least a portion of which is fixedly disposed in the fixed member, and when the rowing member is in the second position, the telescopic rod is compressed in the fixed member; when the rowing member is in the first position, the telescopic rod extends out of the fixed member.

[0018] When the marking member is in the second position, the telescopic rod can be compressed at least partially therein, that is, the compression rod is compressed in the fixing member, so that at least a portion of the fixing member can be fitted with the marking member; when the marking member is in the first position, the telescopic rod extends out of the fixing member, so that an extended space for the marking member to rotate is formed between the fixing member and the marking member.

[0019] In some embodiments, the rowing device may further include a driving assembly, which is transmission-connected to the telescopic rod, and the driving assembly is suitable for driving the telescopic rod to extend or compress.

[0020] In this way, the telescopic rod can be extended or compressed, thereby adjusting the distance between the rowing member and the fixing member, and further realizing the switching of the rowing member between the first position and the second position.

[0021] In some embodiments, the driving assembly may include a motor. The motor can efficiently convert electrical energy into mechanical energy, thereby driving the rotating shaft and the telescopic member to work. The motor has stable performance and low failure rate, which can improve the overall reliability of the rowing device.

[0022] In some embodiments, the fixing member may include a fixing portion and a rotating portion, the rotating portion is movably connected to the fixing portion, and the telescopic rod is connected to the rotating portion so that the telescopic rod rotates along its own telescopic direction.

[0023] The rotating part is movably connected to the fixed part, and the telescopic rod is connected to the rotating part, so that the telescopic rod can move relative to the fixed part. In this way, the paddling direction of the rowing member can be adjusted, thereby adjusting the movement direction of the fixed member, making the movement of the vehicle more flexible and controllable.

[0024] In some embodiments, the fixed portion may include a circular guide rail, and the rotating portion may include a slider matched with the circular guide rail, and the slider rotates along the circular guide rail.

[0025] In this way, the circular guide rail can play a good guiding role for the slider, so that the slider can rotate along the circular guide rail, and then drive the rowing member to rotate to any direction with the telescopic direction of the telescopic rod itself as the axis, so that the vehicle can move in any direction. The vehicle can travel more flexibly in the water and can face complex underwater terrain more calmly.

[0026] In some embodiments, the rowing member may further include a connecting member, which is connected to an end of the telescopic rod away from the fixing member, and the connecting member is movably connected to the rotating shaft.

[0027] The connecting piece is used to connect the telescopic rod and the rotating shaft, so that the rotating shaft can be connected to multiple telescopic rods, thereby ensuring that the telescopic rods play a good supporting role on the rotating shaft and the paddle board.

[0028] In some embodiments, the connecting member may include a first connecting member and a second connecting member, and the first connecting member and the second connecting member are arranged on both sides of the paddle board along the extending direction of the rotating shaft.

[0029] In this way, the first connecting member and the second connecting member can both connect the telescopic rod and the rotating shaft, thereby reducing the deflection of the paddle board during the sliding process, thereby reducing the interference of the deflection on the movement direction and improving the stability of the rowing device.

[0030] In some embodiments, the telescopic rod may include a first telescopic rod and a second telescopic rod, the fixing member may include a first fixing member and a second fixing member, the first telescopic rod and the first fixing member are correspondingly connected to the first connecting member, and the second telescopic rod and the second fixing member are correspondingly connected to the second connecting member.

[0031] In this way, the first telescopic rod and the first fixing member are connected to the first connecting member accordingly, and the second telescopic rod and the second fixing member are connected to the second connecting member accordingly, so that both sides of the rowing member can be supported by the telescopic rod and the fixing member, thereby making the structure of the rowing device more stable.

[0032] In a second aspect, the present application also provides a battery pack, which may include the above-mentioned rowing device.

[0033] In some embodiments, the battery pack may further include a battery pack side guard plate disposed on the periphery of the battery pack, and the line member constitutes at least a portion of the battery pack side guard plate.

[0034] The battery pack side guard plate can support and protect the battery pack. The marking member constitutes at least a part of the battery pack side guard plate. When the marking member is not needed, the marking member can be located outside the battery pack to protect the battery pack.

[0035] In some embodiments, a plurality of rowing devices may be included, and the plurality of rowing devices may be arranged along the length direction of the vehicle body, and the battery pack side guard plate may include a plurality of rowing members.

[0036] Multiple rowing devices can interact with water to provide power to the vehicle, so that compared with a single rowing device, multiple rowing devices can provide more power, thereby allowing the vehicle to leave the water faster.

[0037] In some embodiments, a first battery pack side guard plate and a second battery pack side guard plate may be included, and the first battery pack side guard plate and the second battery pack side guard plate are arranged along the width direction of the vehicle body.

[0038] Since the battery pack side guard plate can include multiple marking members, the multiple marking members can be arranged along the length direction of the vehicle body, and the first battery pack side guard plate and the second battery pack side guard plate are arranged along the width direction of the vehicle body. In this way, a left marking member and a right marking member can be formed respectively. By controlling the speed and direction of the left marking member and the right marking member, the driving direction of the vehicle can be controlled, so that the vehicle can escape safely and quickly.

[0039] In a third aspect, the present application further provides a vehicle, which may include the above-mentioned rowing device or battery pack. It should be noted that the technical effects brought about by the implementation methods of the second and third aspects can all refer to the technical effects brought about by the corresponding implementation methods in the first aspect, and will not be repeated here.

[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0056] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. It can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0057] In the embodiments of the present invention, the terms "comprises", "comprising" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, article or device including the element.

[0058] In the embodiments of the present invention, words such as "exemplary" or "for example" are used to indicate examples, illustrations or explanations.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0059] With the rapid development of electric vehicle technology, the situations encountered by cars during travel are becoming more and more diverse, and the functions of cars are becoming more and more diversified.

[0060] During travel, the vehicle may encounter unexpected wading. Since the vehicle cannot move normally in the water, it may be trapped in the water and unable to escape danger, which greatly threatens the personal safety of the driver and passengers.

[0061] In the prior art, in order to deal with the situation of vehicles wading, the vehicles are equipped with float valves. When the vehicle falls into the water, the float valve is inflated and opened, so that the vehicle can float on the water surface, thereby reducing the harm to the vehicle and the driver and passengers. However, the vehicle still cannot move normally and it is difficult to get out of the water autonomously to eliminate the danger.

[0062] In addition, there is an emergency rescue device for flood disasters. A paddle is installed on each side of the lifeboat. Paddle boards are fixedly installed outside the two paddles. By starting the transmission motor in the bottom protection box of the lifeboat, the transmission shaft and gears are driven to rotate, thereby driving the paddles on both sides to rotate, and then the paddle boards are rotated to enable the lifeboat to move in the flood. However, the paddles of this rescue device are fixed in position and cannot be adjusted, and the adaptability to the vehicle is not high.

[0063] In view of this, an embodiment of the present application provides a rowing device suitable for rowing in water, so that a vehicle can move in water and escape from danger. The rowing device adjusts the distance between the rowing member and the fixed member through a movable member, so that the rowing member can be close to or away from the fixed member, so that the rowing member can be folded up when not in use, ensuring the smooth and beautiful appearance of the vehicle.

[0064] The embodiments provided in this application are described in detail below in conjunction with the accompanying drawings.

[0065] Please refer to Figure 1 , Figure 1 This is a structural schematic diagram of a rowing device 100 provided in an embodiment of the present application. The rowing device 100 may include a fixing member 1. The fixing member 1 may be a vehicle body, a ship body, or a wading component fixedly connected to the vehicle body or the ship body. The fixing member 1 cannot move in the water by its own power.

[0066] The rowing device 100 may further include a rowing member 3, which may be connected to the fixing member 1 to provide power to enable the fixing member 1 to move in the water, thereby getting out of the wading predicament.

[0067] Exemplarily, the row member 3 may be a jet device, which generates a reaction force by jetting high-pressure gas outward, and can drive the fixing member 1 to move in the opposite direction of the jetting direction.

[0068] Exemplarily, the rowing member 3 may be an oar, which creates water waves and causes the water waves to generate a reaction force on the fixing member 1, thereby pushing the fixing member 1 to move.

[0069] Please refer to Figure 2 , Figure 2 for Figure 1 The rowing device 100 is a schematic structural diagram in which the rowing member 3 is away from the fixed member 1. The rowing device 100 may further include a movable member 2. The movable member 2 may be connected between the fixed member 1 and the rowing member 3, and the movable member 2 is suitable for adjusting the distance between the rowing member 3 and the fixed member 1.

[0070] In this way, the movable part 2 can make the rowing member 3 approach or move away from the fixed part 1. When the rowing device 100 is not in use, the movable part 2 can adjust the rowing member 3 to be close to the fixed part 1, so that the rowing member 3 is not easily exposed to the field of vision, thereby improving the flatness and beauty of the fixed part 1; when wading or other situations where the rowing device 100 needs to be used, the movable part 2 can adjust the rowing member 3 to be away from the fixed part 1, so that the rowing member 3 interacts with the surrounding environment and drives the fixed part 1 to move.

[0071] Please refer to Figure 3 , Figure 3 for Figure 2 The rowing member 3 in the rowing device 100 is a schematic structural diagram when rotating. In some embodiments of the present application, the rowing member 3 is rotatably connected to the movable member 2.

[0072] In this way, the rowing device 100 can generate a thrust on the water through the rotation of the rowing member 3, and the water will generate a reaction force on the rowing member 3, thereby driving the fixing member 1 to move.

[0073] Please continue to refer to Figure 3In some embodiments of the present application, the rowing member 3 may include a paddle board 31 and a rotating shaft 32 connected to the paddle board 31 , and the rotating shaft 32 is rotatably connected to one end of the movable member 2 so that the paddle board 31 rotates relative to the movable member 2 .

[0074] Since the shaft 32 is rotatably connected to one end of the movable part 2, the paddle board 31 is connected to the shaft 32, and the paddle board 31 can rotate around the central axis of the shaft 32, so that the paddle board 31 can rotate relative to the movable part 2, and further drive the fixed part 1 to move.

[0075] In some possible structural designs, the paddle board 31 may be a flat plate, so that the surface of the paddle board 31 is flatter after being stored. In other possible structural designs, the paddle board 31 may be spiral, so that the paddle board 31 slides more smoothly, thereby making the vehicle run more smoothly. The shape of the paddle board 31 can be adjusted according to actual needs, and this application does not make any further restrictions on this.

[0076] In some embodiments, the rowing device 100 may further include a first drive assembly, which may be transmission-connected to the rotating shaft 32. The drive assembly 4 may provide power to drive the rotating shaft 32 to rotate, thereby driving the paddle board 31 to rotate around the central axis of the rotating shaft 32, thereby generating an interaction force with the water to drive the fixing member 1 to move.

[0077] Please refer to Figure 2 In some embodiments of the present application, when the movable member 2 adjusts the distance between the marking member 3 and the fixed member 1, the marking member 3 has at least a first position. When the marking member 3 is located at the first position, an extended space is formed between the fixed member 1 and the marking member 3 in which the marking member 3 can rotate.

[0078] When the marking member 3 is located at the first position, an extended space is formed between the fixing member 1 and the marking member 3 for the marking member 3 to rotate. Since the extended space is required for the marking member 3 to rotate, the distance between the marking member 3 and the fixing member 1 is greater than or equal to the distance from the central axis of the rotating shaft 32 to the edge of the paddle board 31. In this way, the fixing member 1 will not interfere with the paddle board 31, so that the paddle board 31 can rotate around the central axis of the rotating shaft 32.

[0079] Please refer to Figure 1 In some embodiments of the present application, when the movable member 2 adjusts the distance between the marking member 3 and the fixed member 1, the marking member 3 may also have a second position. When the marking member 3 is in the second position, at least a portion of the fixed member 1 is in contact with the marking member 3.

[0080] In this way, when the rowing member 3 is in the second position, the distance between the rowing member 3 and the fixing member 1 is the shortest, so that when the rowing member 3 is not used to generate power, the rowing member 3 can be on the surface of the fixing member 1 to ensure the overall beauty.

[0081] Continue to refer to Figure 2 In some embodiments of the present application, the fixing member 1 is provided with a receiving groove 13 , and when the rowing member 3 is in the second position, the rowing member 3 is received in the receiving groove 13 .

[0082] In this way, when the marking member 3 is in the second position, the marking member 3 is accommodated in the accommodation groove 13, so that the surface of the marking device 100 is smoother and more beautiful, and it is prevented that the marking member 3 protrudes from the surface of the fixing member 1 when the marking member 3 is not in use, causing scratches or affecting the normal driving of the vehicle.

[0083] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the movable member 2 may include a telescopic rod 21, at least a portion of which is fixedly disposed in the fixed member 1. When the rowing member 3 is in the second position, the telescopic rod 21 is compressed in the fixed member 1; when the rowing member 3 is in the first position, the telescopic rod 21 extends out of the fixed member 1.

[0084] When the marking member 3 is in the second position, the telescopic rod 21 can be compressed at least partially therein, that is, the compression rod is compressed in the fixing member 1, so that at least a portion of the fixing member 1 can be fitted with the marking member 3; when the marking member 3 is in the first position, the telescopic rod 21 extends out of the fixing member 1, so that an extended space for the marking member 3 to rotate is formed between the fixing member 1 and the marking member 3.

[0085] In some possible structural designs, the telescopic rod 21 may include a hydraulic rod 211. The hydraulic rod 211 can accurately control the telescopic length and speed of the hydraulic rod 211 through a hydraulic system, thereby achieving accurate adjustment of the rowing member 3. In addition, since the hydraulic rod 211 has a strong load-bearing capacity and good stability, it can well cope with complex underwater conditions, thereby enhancing the adaptability of the vehicle to wading conditions.

[0086] In some other possible structural designs, the telescopic rod 21 may further include a linear guide rail and a sliding shaft, so that the sliding shaft can slide in the linear guide rail to achieve the extension and contraction of the telescopic rod 21.

[0087] In other possible structural designs, the telescopic rod 21 may also include other components with telescopic functions, which can be selected according to specific circumstances and are not further limited in this application.

[0088] In some embodiments of the present application, the rowing device 100 may further include a second driving assembly, which is transmission-connected to the telescopic rod 21 , and the driving assembly 4 is suitable for driving the telescopic rod 21 to extend or compress.

[0089] In this way, the telescopic rod 21 can be extended or compressed, so as to adjust the distance between the running member 3 and the fixing member 1, and further realize the switching of the running member 3 between the first position and the second position.

[0090] In some embodiments, the first drive assembly and the second drive assembly can be the same drive assembly 4, which can provide power for the rotation of the rotating shaft 32 and the extension and retraction of the telescopic rod 21. In this way, the number of components of the rowing device 100 can be reduced and the space occupied by the rowing device 100 can be saved.

[0091] In some embodiments of the present application, the driving assembly 4 may include a motor 41. The motor 41 can efficiently convert electrical energy into mechanical energy, thereby driving the rotating shaft 32 and the telescopic rod 21 to work. The motor 41 has stable performance and low failure rate, which can improve the overall reliability of the rowing device 100.

[0092] Please refer to Figure 1 In some embodiments, the rowing device 100 may further include a motor connection circuit 6, which may connect the vehicle battery pack 200 to the motor 41, thereby outputting electrical energy to the motor 41, and further driving the rotating shaft 32 and the telescopic rod 21 to work.

[0093] Please refer to Figure 4 , Figure 4 A structural schematic diagram of a fixing member 1 provided in an embodiment of the present application. In some embodiments of the present application, the fixing member 1 may include a fixing portion 11 and a rotating portion 12, the rotating portion 12 is movably connected to the fixing portion 11, and the telescopic rod 21 is connected to the rotating portion 12 so that the telescopic rod 21 rotates along its own telescopic direction.

[0094] The rotating part 12 is movably connected to the fixed part 11, and the telescopic rod 21 is connected to the rotating part 12, so that the telescopic rod 21 can be movable relative to the fixed part 11. In this way, the paddling direction of the rowing member 3 can be adjusted, thereby adjusting the movement direction of the fixed member 1, making the movement of the vehicle more flexible and controllable.

[0095] In some embodiments of the present application, the fixing portion 11 may include a circular guide rail 111 , and the rotating portion 12 may include a slider 121 cooperating with the circular guide rail 111 , and the slider 121 may rotate along the circular guide rail 111 .

[0096] In this way, the circular guide rail 111 can play a good guiding role for the slider 121, so that the slider 121 can rotate along the circular guide rail 111, and then drive the rowing member 3 to rotate to any direction with the telescopic direction of the telescopic rod 21 itself as the axis, so that the vehicle can move in any direction, the vehicle can travel more flexibly in the water, and can face complex underwater terrain more calmly.

[0097] Please continue to refer to Figure 1 , Figure 2 or Figure 3 In order to make the structure of the rowing device 100 more stable, in some embodiments, the telescopic rod 21 may include a plurality of telescopic rods 21, and the plurality of telescopic rods 21 are arranged along an extension direction perpendicular to the rotation axis 32, and the plurality of telescopic rods 21 are connected to the fixing member 1 and the rowing member 3. In this way, the deflection of the telescopic rod 21 during movement can be reduced, thereby affecting its telescopic performance. Exemplarily, the telescopic rods 21 may include 2, 3 or 4.

[0098] In order to facilitate the connection between the multiple telescopic rods 21 and the rowing member 3, in some embodiments of the present application, the rowing member 3 may further include a connecting member 5, which is connected to one end of the telescopic rod 21 away from the fixing member 1, and the connecting member 5 is movably connected to the rotating shaft 32.

[0099] The connecting member 5 is used to connect the telescopic rod 21 and the rotating shaft 32 , so that the rotating shaft 32 can be connected to multiple telescopic rods 21 , thereby ensuring that the telescopic rod 21 plays a good supporting role on the rotating shaft 32 and the paddle board 31 .

[0100] In some embodiments of the present application, the connecting member 5 may include a first connecting member 5A and a second connecting member 5B, and the first connecting member 5A and the second connecting member 5B are arranged on both sides of the paddle board 31 along the extension direction of the rotating shaft 32 .

[0101] In this way, the first connecting member 5A and the second connecting member 5B can both connect the telescopic rod 21 and the rotating shaft 32, thereby reducing the deflection of the paddle board 31 during the sliding process, thereby reducing the interference of the deflection on the movement direction and improving the stability of the rowing device 100.

[0102] In some embodiments of the present application, the telescopic rod 21 may include a first telescopic rod 21A and a second telescopic rod 21B, the fixing member 1 may include a first fixing member 1B and a second fixing member 1B, the first telescopic rod 21A and the first fixing member 1B are correspondingly connected to the first connecting member 5A, and the second telescopic rod 21B and the second fixing member 1B are correspondingly connected to the second connecting member 5B.

[0103] In this way, the first telescopic rod 21A and the first fixing member 1B are connected to the first connecting member 5A correspondingly, and the second telescopic rod 21B and the second fixing member 1B are connected to the second connecting member 5B correspondingly, so that both sides of the rowing member 3 can be supported by the telescopic rod 21 and the fixing member 1, thereby making the structure of the rowing device 100 more stable.

[0104] In some embodiments, the first telescopic rod 21A may include a plurality of telescopic rods 21 , and the second telescopic rod 21B may also include a plurality of telescopic rods 21 . Exemplarily, the total number of the telescopic rods 21 may be 4, 6, or 8.

[0105] Please refer to Figure 5 and Figure 6 , Figure 5 This is one of the structural schematic diagrams of a battery pack 200 provided in an embodiment of the present application. Figure 6 This is a second structural schematic diagram of a battery pack 200 provided in an embodiment of the present application. The embodiment of the present application may also provide a battery pack 200, which may include the above-mentioned rowing device 100.

[0106] In some embodiments of the present application, the battery pack 200 may further include a battery pack side guard plate 201 disposed on the periphery of the battery pack 200 , and the marking member 3 may constitute at least a portion of the battery pack side guard plate 201 .

[0107] The battery pack side guard plate 201 can support and protect the battery pack 200 . The marking member 3 constitutes at least a part of the battery pack side guard plate 201 . When the marking member 3 is not needed, the marking member 3 can be located outside the battery pack 200 to protect the battery pack 200 .

[0108] In one possible structural design, please refer to Figure 5 The fixing member 1 may include at least part of the battery pack side guard plate 201. The fixing member 1 is provided with a receiving groove 13. The marking member 3 may be received in the receiving groove 13 and together with the fixing member 1 form the battery pack side guard plate 201. In this way, the outer surface of the battery pack side guard plate 201 can be made flat, and the receiving groove 13 can play a role in positioning the marking member 3.

[0109] In another possible structural design, please refer to Figure 6 The fixing member 1 may be a battery pack 200, the telescopic rod 21 is directly connected to the surface of the battery pack 200, and the row member 3 may constitute the battery pack side guard plate 201. In this way, the structure of the battery pack 200 may be simpler.

[0110] Please continue to refer to Figure 5 and Figure 6In some embodiments of the present application, the battery pack 200 may include a plurality of rowing devices 100 , the plurality of rowing devices 100 are arranged along the length direction of the vehicle body, and the battery pack side guard plate 201 may include a plurality of rowing members 3 .

[0111] The plurality of rowing devices 100 can interact with water to provide power for the vehicle to move forward. Thus, compared with one rowing device 100, the plurality of rowing devices 100 can provide stronger power, thereby enabling the vehicle to leave the water faster.

[0112] In some embodiments of the present application, the battery pack 200 may include a first battery pack side guard plate and a second battery pack side guard plate, and the first battery pack side guard plate and the second battery pack side guard plate are arranged along the width direction of the vehicle body. The first battery pack side guard plate and the second battery pack side guard plate are consistent with the structure of the battery pack side guard plate 201 described above.

[0113] Since the battery pack side guard plate 201 can include multiple marking members 3, the multiple marking members 3 can be arranged along the length direction of the vehicle body, and the first battery pack side guard plate and the second battery pack side guard plate are arranged along the width direction of the vehicle body. In this way, a left marking member 3A and a right marking member 3B can be formed respectively. By controlling the speed and direction of the left marking member 3A and the right marking member 3B, the driving direction of the vehicle can be controlled, so that the vehicle can escape safely and quickly.

[0114] In the first embodiment, please refer to Figure 7 , Figure 7 The schematic diagram of the state of the row member 3 when the vehicle turns right is provided in an embodiment of the present application. When the left row member 3A does not rotate and the right row member 3B rotates forward, the vehicle starts to turn right. The left row member 3A does not rotate and will not generate a forward thrust on the left side of the vehicle; the right row member 3B rotates forward and pushes the water backward, and the water will give the right row member 3B a forward reaction force, which will act on the right side of the vehicle. In this case, the vehicle will be subjected to a rightward torque, because the right side is subjected to a forward force, while the left side is not subjected to the same force, and this torque will cause the vehicle to turn right around its center.

[0115] In the second embodiment, please refer to Figure 8 , Figure 8 The schematic diagram of the state of the row member 3 when the vehicle turns left is provided in an embodiment of the present application. When the right row member 3B does not rotate and the left row member 3A rotates forward, the vehicle starts to turn left. Similar to the above right turn, the right row member 3B does not rotate and will not generate a forward thrust on the right side of the vehicle; the left row member 3A rotates forward and pushes the water backward, and the water gives the left row member 3A a forward reaction force, which acts on the left side of the vehicle, and the vehicle is subjected to a leftward torque, which causes the vehicle to turn left around its center.

[0116] In the third embodiment, please refer to Fig. 9 , Fig. 9 This is a schematic diagram of the state of the rowing member 3 when the vehicle turns around in an embodiment of the present application. When the paddles 31 on the left and right sides rotate in opposite directions, the vehicle starts to turn around. The right rowing member 3B rotates forward, pushing the water backward, and the water gives the right rowing member 3B a forward reaction force, which acts on the right side of the vehicle. The left rowing member 3A rotates in the opposite direction, pushing the water forward, and the water gives the right rowing member 3B a backward reaction force, which acts on the left side of the vehicle. In this case, the vehicle rotates rightward around its center, thereby completing the U-turn.

[0117] In the fourth embodiment, please refer to Fig.10 , Fig.10 A schematic diagram of the state of a rowing member 3 when a vehicle moves backward is provided in an embodiment of the present application. When the paddle boards 31 on the left and right sides rotate in opposite directions, the vehicle starts to move backward. Since the paddle boards 31 on the left and right sides rotate in opposite directions, water will give a backward reaction force to the left rowing member 3A and the right rowing member 3B, thereby pushing the vehicle to move backward.

[0118] The embodiment of the present application may also provide a vehicle, which may include the rowing device 100 or the battery pack 200. The vehicle may actively change the state of the rowing device 100 according to the environment in which it is located. When the vehicle is in water, the paddle board 31 is controlled to rotate around the rotating shaft 32 to provide power for the vehicle, thereby enabling the vehicle to travel in water. In addition, by controlling the rotation speed and direction of the left and right rowing members 3B, the driving direction of the vehicle may be controlled, so that the vehicle can escape safely and quickly.

[0119] When the vehicle is in an air environment, the rowing device 100 can also be turned on, and the extension length of the telescopic rod 21 and the rotation position of the paddle board 31 can be determined according to actual conditions to facilitate mud and sand cleaning and maintenance work on the rowing device 100.

[0120] When the vehicle is traveling on the road, the line member 3 is retracted to a state of being in contact with the fixing member 1, so that the appearance of the vehicle is smoother and more beautiful, and at the same time, the aerodynamic resistance of the whole vehicle can be reduced.

[0121] When the vehicle encounters an emergency on the road and needs emergency braking, the rowing device 100 is turned on and the paddle board 31 is rotated so that the paddle board 31 is perpendicular to the ground, thereby increasing the wind resistance and helping the vehicle to brake quickly. Specifically, the extension of the telescopic rod 21 is controlled by the motor 41, and then the shaft 32 is driven to rotate the paddle board 31 90° so that the paddle board 31 is perpendicular to the ground, thereby increasing the wind resistance to a certain extent and helping the car to brake quickly. The extension length of the telescopic rod 21 and the rotation angle of the paddle board 31 can be determined according to the actual situation and the actual space size.

[0122] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0123] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
