[0046] like Figure 1 As shown, the embodiment provides a means of transportation that can be used as a daily mode of transportation for users. The means of transportation can be a two-wheeled vehicle, for example, an electric bicycle.

[0047] In other embodiments, the means of transportation may also be a motorcycle.

[0048] Of course, in other embodiments, the means of transportation can also be electric balance vehicles, electric tricycles, or other similar vehicles.

[0049] like Figures 1 to 5As shown, in some embodiments, the vehicle can include a frame body 100, a first moving wheel 210, a second moving wheel 220, and a cooling system 300. Wherein, an axle 212 of the first moving wheel 210 is rotatably connected to one end of the frame body 100. That is, the first moving wheel 210 is rotatably installed at one end of the frame body 100. The second moving wheel 220 is rotatably connected to an end of the frame body 100 away from the first moving wheel 210, and an axis of rotation of the second moving wheel 220 can be parallel to an axis of rotation of the first moving wheel 210. In some embodiments, the first moving wheel 210 can be a front wheel of an electric bicycle, and the second moving wheel 220 can be a rear wheel of the electric bicycle.

[0050] In other embodiments, the first moving wheel 210 can be a rear wheel of an electric bicycle, and the second moving wheel 220 can be a front wheel of the electric bicycle.

[0051] In some embodiments, the cooling system 300 includes a water pump 310 and a heat exchange pipeline 320, which are connected in communication and form a circulating loop of cooling liquid. Wherein, the water pump 310 can serve as a power source in the cooling system 300 and can drive the cooling liquid to circulate and flow in the water pump 310 and the heat exchange pipeline 320. In embodiments, the water pump 310 includes an impeller 312, which can be drivingly connected to the axle 212 so as to be driven by the axle 212 to rotate. The heat exchange pipeline 320 can be arranged on the frame body 100 and can exchange heat with the frame body 100.

[0052] In the process of the vehicle traveling, the first moving wheel 210 and the second moving wheel 220 can rotate relative to the frame body 100. When the first moving wheel 210 rotates relative to the frame body 100, the impeller 312 in the water pump 310 can be driven by the axle 212 to rotate, that is, the water pump 310 can be operated to drive the cooling liquid in the cooling system 300 to circulate and flow. In this process, the cooling liquid can exchange heat with the frame body 100 to cool and heat-dissipate the frame body 100, without consuming the energy of the vehicle, achieving energy-saving effect. At the same time, it will not generate a large resistance to the travel of the vehicle, reducing the increase of energy consumption in the process of the vehicle traveling. At the same time, it can not be affected by the energy of the vehicle, that is, even if the vehicle is out of power or out of oil, as long as the vehicle can travel, the cooling system 300 can provide the cooling and heat-dissipating function for the frame body 100.

[0053] As Figure 1 and Figure 2As shown, the frame body 100 is configured with a ground proximal side 101, i.e. the side of the frame body 100 facing the ground. In some embodiments, the frame body 100 comprises a beam assembly 110, a handlebar 120, a front fork 130 and a driving member 141. The handlebar 120 and the front fork 130 can be mounted at the same end of the beam assembly 110, and the handlebar 120 can be located at the side of the beam assembly 110 away from the ground proximal side 101, and the front fork 130 can be mounted at the side of the beam assembly 110 facing the ground proximal side 101, and the wheel shaft 212 of the first moving wheel 210 is rotatably connected to the end of the front fork 130 away from the beam assembly 110 by a bearing. The second moving wheel 220 can be rotatably mounted at the end of the beam assembly 110 away from the first moving wheel 210, and is generally located at the side of the beam assembly 110 facing the ground proximal side 101. In embodiments, the driving member 141 can be mounted on the beam assembly 110 and drivingly connected to the second moving wheel 220. That is, the second moving wheel 220 can serve as the driving wheel in the vehicle. During use, the second moving wheel 220 can be driven to rotate by the driving member 141, so as to drive the first moving wheel 210 to rotate and enable the vehicle to move.

[0054] In some embodiments, the beam assembly 110 can comprise a connecting seat 111, a cross beam 112, a vertical rod 113 and a rear fork 114. The connecting seat 111, the cross beam 112 and the vertical rod 113 can be sequentially connected. The connecting seat 111 and the cross beam 112, and the cross beam 112 and the vertical rod 113 can be fixedly connected by means of integral molding, rivet connection or bolt connection, etc. In some embodiments, the cross beam 112 and the vertical rod 113 can generally form a V shape. The cross beam 112 can be made of aluminum alloy.

[0055] In some embodiments, the handlebar 120 can be rotatably mounted at the side of the connecting seat 111 away from the ground proximal side 101, and the rotation axis of the handlebar 120 can be generally parallel to the direction of gravity, and correspondingly, the rotation axis of the handlebar 120 can be perpendicular to the wheel shaft 212 of the first moving wheel 210. The end of the front fork 130 away from the first moving wheel 210 can be rotatably mounted at the side of the connecting seat 111 facing the ground proximal side 101, and the rotation axis of the front fork 130 can coincide with the rotation axis of the handlebar 120. In addition, the front fork 130 can be arranged in the connecting seat 111 and fixedly connected to the handlebar 120, so that the user can adjust the direction of the first moving wheel 210 through the handlebar 120, thereby realizing the steering of the vehicle.

[0056] In some embodiments, the rear fork 114 can generally present a flat V shape, and the open end of the rear fork 114 can be connected to the side of the vertical rod 113 away from the cross beam 112, and the rear fork 114 and the vertical rod 113 can be fixedly connected by means of integral molding, rivet connection or screw connection, etc. The second moving wheel 220 can be rotatably mounted at the end of the rear fork 114 away from the vertical rod 113.

[0057] In some embodiments, the end of the upright 113 connected to the crossbeam 112 may be provided with a mounting cavity 1131, and the driving member 141 may be accommodated in the mounting cavity 1131 and fixedly connected to the upright 113 by means of bolts or other methods. In some embodiments, the driving member 141 may be a motor, and the output shaft of the motor may be parallel to the rotation axis of the second moving wheel 220. The output shaft of the motor may be connected to the second moving wheel 220 through a structure such as a transmission gear and a transmission chain, so that the driving member 141 can drive the second moving wheel 220 to rotate.

[0058] like Figure 1 , Figure 2 and Figure 7 As shown, in some embodiments, the frame body 100 further includes an electrically connected power supply battery 143 and a controller 142. The controller 142 is electrically connected to the drive component 141, thereby allowing the controller 142 to control the operation of the drive component 141, and the power supply battery 143 to supply power to both the controller 142 and the drive component 141. In some embodiments, the controller 142 may also be housed in the mounting cavity 1131 and located on the side of the drive component 141 away from the near-ground side 101. The crossbeam 112 may have a hollow internal structure, allowing the power supply battery 143 to be housed inside the crossbeam 112 and fixed relative to the crossbeam 112 by means of bolts or other methods.

[0059] In some embodiments, the frame body 100 further includes a seat 151, which is connected to the end of the upright 113 away from the crossbeam 112 via a connecting rod 152. Specifically, one end of the connecting rod 152 can be fixedly connected to the seat 151 by welding, bolting, or riveting. The other end of the connecting rod 152 away from the seat 151 can be slidably inserted into the end of the upright 113 away from the crossbeam 112 and can be locked in place by a locking clamp 153 installed on the upright 113. Thus, the user can adjust the height of the seat 151 as needed.

[0060] like Figures 2 to 5 As shown, in some embodiments, the water pump 310 further includes a pump body 311. The pump body 311 may include a main housing 3111 and an end cap 3112. The end cap 3112 may be disposed opposite to the main housing 3111 and cooperate to form a closed cavity 3113. The end cap 3112 may be fixedly connected to the main housing 3111 by means of screw connection, riveting, or welding. A first sealing ring 3114 is also provided between the end cap 3112 and the main housing 3111 to achieve sealing at the connection position between the main housing 3111 and the end cap 3112.

[0061] In some embodiments, the pump body 311 can be sleeved on the periphery of the axle 212, i.e., the axle 212 can pass through the pump body 311, and the pump body 311 can be coaxially arranged with the axle 212. Accordingly, the cavity 3113 can be arranged around the periphery of the axle 212. In some embodiments, the end cover 3112 can be located on the side of the main shell 3111 away from the first moving wheel 210. In addition, the pump body 311 and the axle 212 can rotate relative to each other, and the second sealing ring 3141 can be arranged between the end cover 3112 and the axle 212 to achieve sealing at the connection position.

[0062] In some embodiments, the impeller 312 can be accommodated in the cavity 3113, and the impeller 312 can be fixedly mounted on the axle 212, so that the impeller 312 can rotate relative to the pump body 311. In some embodiments, the water pump 310 further comprises a connecting sleeve 313, which can be sleeved on the axle 212. One end of the connecting sleeve 313 can be provided with a flange, which can be fixedly connected with the hub 211 of the first moving wheel 210 by means of bolts or the like. The other end of the connecting sleeve 313 can pass through the main shell 3111 and extend into the cavity 3113. The impeller 312 can be fixedly sleeved on the periphery of the connecting sleeve 313 by means of interference fit, welding or bolt connection. In addition, the connecting sleeve 313 and the main shell 3111 can be provided with a third sealing ring 3142 at the connection position to achieve sealing at the connection position.

[0063] In some embodiments, the impeller 312 is fixedly arranged relative to the first moving wheel 210. Accordingly, the rotational speed of the impeller 312 can be synchronized with the rotational speed of the first moving wheel 210, i.e., the faster the vehicle travels, the higher the rotational speed of the impeller 312, and the greater the circulating flow speed of the cooling liquid in the cooling system 300, and the higher the heat dissipation capacity. Accordingly, the heat dissipation capacity of the cooling system 300 can be positively correlated with the travel speed of the vehicle, so that the heat dissipation capacity of the cooling system 300 can be matched with the heat generated during the operation of the vehicle, so that the heat generated during the operation of the vehicle frame body 100 can be dissipated in time, and the smooth operation of the vehicle can be ensured.

[0064] As Figure 1 、 Figure 2 、 Figures 6 to 8As shown, the heat exchange pipeline 320 can include a water tank 325, a first heat exchange part 321, a second heat exchange part 322, a third heat exchange part 323 and a fourth heat exchange part 324. The water tank 325 can be integrated on one side of the cross beam 112, and the water tank 325 can share a side wall with the cross beam 112, that is, the water tank 325 can be an integral structure with the cross beam 112. Thus, the volume of the vehicle can be saved, and the vehicle can be lightened. Meanwhile, the cooling liquid in the water tank 325 can exchange heat with the external environment through the cross beam 112 to dissipate the heat of the cooling liquid. In addition, the water tank 325 can extend along the axial direction of the cross beam 112, and can extend from the end of the cross beam 112 close to the connecting seat 111 to the end close to the vertical rod 113.

[0065] In some embodiments, the end of the water tank 325 close to the connecting seat 111 can be provided with a liquid injection port 3251, which can be used to inject cooling liquid into the water tank 325. It can be understood that in the case of non-liquid injection, the liquid injection port 3251 can be sealed by a sealing plug, which can be sealingly and fixedly connected to the inner wall of the liquid injection port 3251 by threaded connection or interference fit. In addition, the end of the water tank 325 close to the vertical rod 113 can be provided with a drain port 3252, which can be used to drain the cooling liquid in the water tank 325. When it is not necessary to drain the cooling liquid in the water tank 325, the drain port 3252 can also be sealed by a sealing plug, and the sealing plug can be sealingly and fixedly connected to the inner wall of the drain port 3252 by threaded connection or interference fit. The drain port 3252 is close to the bottom of the water tank 325, which can facilitate the complete emptying of the cooling liquid in the water tank 325.

[0066] In some embodiments, the side wall of the water tank 325 towards the inside of the cross beam 112 can be attached to the power supply battery 143 and can exchange heat with the power supply battery 143 to remove the heat generated by the power supply battery 143 during operation and cool the power supply battery 143.

[0067] In some embodiments, the third heat exchange part 323 can include a first sub-heat exchange part 3231 and a second sub-heat exchange part 3232, and the first sub-heat exchange part 3231 and the second sub-heat exchange part 3232 can both be S-shaped copper pipe structures. The first sub-heat exchange part 3231 and the second sub-heat exchange part 3232 are attached to the inner wall of the cross beam 112 and are arranged on both sides of the water tank 325. The first sub-heat exchange part 3231 and the second sub-heat exchange part 3232 can both be in contact with the power supply battery 143 to exchange heat with the power supply battery 143 and cool the power supply battery 143. In the embodiment, the first sub-heat exchange part 3231 and the second sub-heat exchange part 3232 can be fixedly connected to the cross beam 112 by pipe fixing buckles and bolts.

[0068] In other embodiments, the first sub-heat exchange part 3231 and the second sub-heat exchange part 3232 can also be heat exchange plates, in which S-shaped or Z-shaped flow channels for the cooling liquid can be configured.

[0069] In some embodiments, the first heat exchange part 321 can be arranged on the side of the driving member 141 facing the controller 142, and the side of the first heat exchange part 321 away from the driving member 141 can be attached to the controller 142. Thus, the first heat exchange part 321 can exchange heat with the driving member 141 and the controller 142, respectively. In some embodiments, the first heat exchange part 321 can be an S-shaped copper pipe structure, which can increase the contact area of the first heat exchange part 321 with the driving member 141 and the controller 142, achieving rapid heat exchange. In addition, the first heat exchange part 321 can be fixed to the housing of the driving member 141 by a pipe fixing buckle and a bolt. The controller 142 can also be fixedly connected to the housing of the driving member 141 by a bolt connection or the like.

[0070] In other embodiments, the first heat exchange part 321 can also be a heat exchange plate, in which S-shaped or Z-shaped flow channels for the cooling liquid can be configured.

[0071] In some embodiments, the second heat exchange part 322 can be arranged on the side of the saddle 151 facing the near-ground side 101, i.e., the second heat exchange part 322 can be arranged on the side of the saddle 151 facing the connecting rod 152. The second heat exchange part 322 can exchange heat with the saddle 151, so that in a hot environment, the temperature of the saddle 151 can be reduced, providing a more cool riding condition for the user and improving the user's riding comfort. In some embodiments, the second heat exchange part 322 can also be an S-shaped copper pipe structure, which can be fixed to the saddle 151 by a pipe fixing buckle and a bolt.

[0072] In other embodiments, the second heat exchange part 322 can also be a heat exchange plate, in which S-shaped or Z-shaped flow channels for the cooling liquid can be configured.

[0073] In some embodiments, the fourth heat exchange part 324 can include a third sub-heat exchange part 3241 and a fourth sub-heat exchange part 3242. The third sub-heat exchange part 3241 and the fourth sub-heat exchange part 3242 can both be straight copper pipe structures and both be substantially parallel to the fork rod of the front fork 130. In embodiments, the third sub-heat exchange part 3241 and the fourth sub-heat exchange part 3242 can be arranged side by side, and both can be fixed to the fork rod of the front fork 130 near the water pump 310 by a pipe fixing buckle and a bolt. During use, the fourth heat exchange part 324 can exchange heat with the external environment, and the heat in the cooling liquid can be dissipated to the external environment, achieving heat dissipation.

[0074] In other embodiments, the third sub-heat exchanging portion 3241 and the fourth sub-heat exchanging portion 3242 can also be in the spiral copper tube structure and be wound on the fork rod of the front fork 130 near the water pump 310.

When the cooling liquid flows through the first heat exchange part 321, the cooling liquid can exchange heat with the driving member 141 and the controller 142 respectively, so as to cool and lower the temperature of the driving member 141 and the controller 142. When the cooling liquid flows through the second heat exchange part 322, the cooling liquid can exchange heat with the saddle 151, so as to cool and lower the temperature of the saddle 151. When the cooling liquid flows through the third heat exchange part 323 and the water tank 325, the cooling liquid can exchange heat with the power supply battery 143, so as to cool and lower the temperature of the power supply battery 143. Meanwhile, when the cooling liquid flows through the water tank 325, the cooling liquid can exchange heat with the external environment through the cross beam 112, so as to dissipate the heat in the cooling liquid. When the cooling liquid flows through the fourth heat exchange part 324, the cooling liquid can exchange heat with the external environment, so as to dissipate the heat in the cooling liquid, so that the cooling liquid can exchange heat with the driving member 141, the controller 142, the power supply battery 143, and the saddle 151 again.

[0079] In the vehicle provided in the embodiments of the present application, the cooling system 300 can be used to cool and lower the temperature of the power supply battery 143, the driving member 141, and the controller 142 simultaneously, reduce the heat accumulation of the power supply battery 143, the driving member 141, and the controller 142, reduce the risk of thermal runaway of the power supply battery 143, improve the use safety of the vehicle, and prolong the service life of the power supply battery 143, the driving member 141, and the controller 142. In addition, the cooling system 300 can also be used to cool and lower the temperature of the saddle 151, and improve the user's riding experience.
