[0024] As Figure 1 shown, in the embodiment, a vehicle is provided, which can be used as a means of transportation for users' daily travel. Among them, the vehicle can be a two-wheeled vehicle. For example, the vehicle can be an electric bicycle.

[0025] In some other embodiments, the vehicle can also be a motorcycle.

[0026] Of course, in some other embodiments, the vehicle can also be a vehicle such as an electric unicycle or an electric tricycle.

[0027] As Figures 1 to 5 shown, in some embodiments, the vehicle may include a frame main body 100, a first moving wheel 210, a second moving wheel 220, and a cooling system 300. Among them, the axle 212 of the first moving wheel 210 is rotatably connected to one end of the frame main body 100. That is, the first moving wheel 210 is rotatably installed at one end of the frame main body 100. The second moving wheel 220 is rotatably connected to the end of the frame main body 100 away from the first moving wheel 210, and the rotation axis of the second moving wheel 220 can be parallel to the rotation axis of the first moving wheel 210. In some embodiments, the first moving wheel 210 can be the front wheel of an electric bicycle, and the second moving wheel 220 can be the rear wheel of an electric bicycle.

[0028] In some other embodiments, the first moving wheel 210 can be the rear wheel of an electric bicycle, and the second moving wheel 220 can be the front wheel of an electric bicycle.

[0029] In some embodiments, the cooling system 300 includes a water pump 310 and a heat exchange pipe 320. The water pump 310 and the heat exchange pipe 320 are connected to form a coolant circulation loop. The water pump 310 can serve as the power source in the cooling system 300, driving the coolant to circulate through the water pump 310 and the heat exchange pipe 320. In some embodiments, the water pump 310 includes an impeller 312, which can be drivingly connected to the axle 212, thereby driving the impeller 312 to rotate. The heat exchange pipe 320 can be arranged on the vehicle frame 100 and can exchange heat with the vehicle frame 100.

[0030] During vehicle movement, the first and second moving wheels 210, 220 can rotate relative to the main frame 100. Rotating the first moving wheel 210 relative to the main frame 100 drives the impeller 312 in the water pump 310 via the wheel axle 212, thereby operating the water pump 310 and circulating the coolant in the cooling system 300. During this process, the coolant exchanges heat with the main frame 100, dissipating heat and cooling the main frame 100 without consuming any vehicle energy, thus achieving energy savings. Furthermore, this system does not significantly hinder the vehicle's movement, minimizing energy consumption during travel. Furthermore, the system is independent of the vehicle's energy source. Even if the vehicle is out of power or fuel, as long as the vehicle is able to move, the cooling system 300 can continue to dissipate heat and cool the main frame 100.

[0031] like Figure 1 and Figure 2 As shown, the frame body 100 is configured with a ground-facing side 101, i.e., the side of the frame body 100 facing the ground. In some embodiments, the frame body 100 includes a beam assembly 110, a handlebar 120, a front fork 130, and a drive member 141. The handlebar 120 and the front fork 130 can be mounted on the same end of the beam assembly 110, with the handlebar 120 being located on the side of the beam assembly 110 facing away from the ground-facing side 101. The front fork 130 can be mounted on the side of the beam assembly 110 facing the ground-facing side 101. The axle 212 of the first moving wheel 210 is rotatably connected to the end of the front fork 130 away from the beam assembly 110 via a bearing. The second moving wheel 220 is rotatably mounted on the end of the beam assembly 110 away from the first moving wheel 210 and is generally located on the side of the beam assembly 110 facing the ground-facing side 101. In some embodiments, the drive member 141 can be mounted on the beam assembly 110 and is in transmission connection with the second moving wheel 220. That is, the second moving wheel 220 can be used as a driving wheel in the vehicle. During use, the second moving wheel 220 can be driven by the driving member 141 to rotate so that the vehicle can move forward, thereby driving the first moving wheel 210 to rotate.

[0032] In some embodiments, the beam frame assembly 110 may include 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 may be connected and arranged in sequence. Among them, 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 such as integral molding, riveting, or bolt connection. In some embodiments, the cross beam 112 and the vertical rod 113 may generally form a V shape. The cross beam 112 may be made of aluminum alloy.

[0033] In some embodiments, the handlebar 120 may be rotatably installed on the side of the connecting seat 111 facing away from the near-ground side 101, and the rotation axis of the handlebar 120 may be generally parallel to the direction of gravity. Correspondingly, the rotation axis of the handlebar 120 may be perpendicular to the axle 212 of the first moving wheel 210. One end of the front fork 130 away from the first moving wheel 210 may be rotatably installed on the side of the connecting seat 111 facing the near-ground side 101, and the rotation axis of the front fork 130 may coincide with the rotation axis of the handlebar 120. In addition, the front fork 130 may pass through the connecting seat 111 and be fixedly connected to the handlebar 120, so that the user can adjust the direction of the first moving wheel 210 through the handlebar 120, and thus realize the steering of the vehicle.

[0034] In some embodiments, the rear fork 114 may generally be in a lying V shape. The open end of the rear fork 114 may be connected to the side of the vertical rod 113 facing away from the cross beam 112, and the rear fork 114 and the vertical rod 113 can be fixedly connected by means such as integral molding, riveting, or screw connection. The second moving wheel 220 may be rotatably installed at the end of the rear fork 114 away from the vertical rod 113.

[0035] In some embodiments, an installation cavity 1131 may be configured at one end of the vertical rod 113 for connecting to the cross beam 112. The driving member 141 may be accommodated in the installation cavity 1131 and fixedly connected to the vertical rod 113 by means such as bolt connection. In some embodiments, the driving member 141 may be selected as a motor. The output shaft of the motor may be parallel to the rotation axis of the second moving wheel 220, and the output shaft of the motor may be in transmission connection with the second moving wheel 220 through structures such as transmission gears and transmission chains. Thus, the second moving wheel 220 can be driven to rotate by the driving member 141.

[0036] Such as Figure 1 , Figure 2 and Figure 7As shown, in some embodiments, the frame body 100 further includes a power supply battery 143 and a controller 142 that are electrically connected. The controller 142 can be electrically connected to the driving member 141. Thus, the operation of the driving member 141 can be controlled by the controller 142, and the controller 142 and the driving member 141 can be powered by the power supply battery 143. In the embodiment, the controller 142 can also be accommodated in the installation cavity 1131 and can be located on the side of the driving member 141 away from the near-ground side 101. The inside of the cross beam 112 can be a hollow structure, and the power supply battery 143 can be accommodated inside the cross beam 112 and can be fixedly arranged relative to the cross beam 112 by means such as bolt connection.

[0037] In some embodiments, the frame body 100 further includes a seat 151. The seat 151 is connected to one end of the vertical rod 113 away from the cross beam 112 through a connecting rod 152. Specifically, one end of the connecting rod 152 can be fixedly connected to the seat 151 by means such as welding, bolt connection or rivet riveting. The other end of the connecting rod 152 away from the seat 151 can be slidably inserted into one end of the vertical rod 113 away from the cross beam 112 and can be locked and fixed by a locking hoop 153 installed on the vertical rod 113. Thus, the user can adjust the height of the seat 151 as needed.

[0038] As Figures 2 to 5 As shown, in some embodiments, the water pump 310 further includes a pump body 311. The pump body 311 can include a main housing 3111 and an end cover 3112. The end cover 3112 can be disposed opposite to the main housing 3111 and cooperate to enclose a closed cavity 3113. Among them, the end cover 3112 can be fixedly connected to the main housing 3111 by means such as screw connection, rivet riveting or welding. And a first sealing ring 3114 is further arranged between the end cover 3112 and the main housing 3111, which can realize the sealing of the connection position between the main housing 3111 and the end cover 3112.

[0039] In some embodiments, the pump body 311 can be sleeved on the periphery of the wheel axle 212, that is, the wheel axle 212 can pass through the pump body 311, and the pump body 311 can be coaxially arranged with the wheel axle 212. Correspondingly, the cavity 3113 can be arranged around the periphery of the wheel axle 212. In some embodiments, the end cover 3112 can be located on the side of the main housing 3111 away from the first moving wheel 210. In addition, relative rotation can occur between the pump body 311 and the wheel axle 212, and a second sealing ring 3141 can be arranged between the end cover 3112 and the wheel axle 212, which can realize the sealing of the connection position.

[0040] In an embodiment, the impeller 312 can be received in the cavity 3113, and the impeller 312 can be fixedly mounted on the wheel shaft 212. Accordingly, the impeller 312 can rotate relative to the pump body 311. In some embodiments, the water pump 310 further includes a connecting sleeve 313. The connecting sleeve 313 can be sleeved on the wheel shaft 212. One end of the connecting sleeve 313 can be configured with a flange, and the flange can be fixedly connected to the hub 211 of the first moving wheel 210 by means of bolt connection or the like. The other end of the connecting sleeve 313 can pass through the main housing 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 or the like. In addition, a third sealing ring 3142 can be provided at the connection position between the connecting sleeve 313 and the main housing 3111 to achieve sealing at the connection position.

[0041] In an embodiment, the impeller 312 is fixedly arranged relative to the first moving wheel 210. Accordingly, the rotation speed of the impeller 312 can be synchronized with the rotation speed of the first moving wheel 210, that is, the faster the vehicle travels, the higher the rotation speed of the impeller 312, the greater the circulating flow rate of the coolant 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 traveling speed of the vehicle, so that the heat dissipation capacity of the cooling system 300 can match the heat generated during the operation of the vehicle, and the heat during the operation of the frame body 100 can be dissipated in time to ensure the smooth operation of the vehicle.

[0042] As Figure 1 , Figure 2 , Figures 6 to 8 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. Among them, the water tank 325 can be integrated on one side inside the cross beam 112. The water tank 325 can share one side wall with the cross beam 112, that is, the water tank 325 and the cross beam 112 can be of an integral structure. Thus, the volume of the vehicle can be saved and the vehicle can be made lighter. At the same time, the coolant in the water tank 325 can exchange heat with the external environment through the cross beam 112 to dissipate the heat of the coolant. In addition, the water tank 325 can be arranged to extend along the axial direction of the cross beam 112 and can extend from one end of the cross beam 112 close to the connection seat 111 to one end close to the vertical rod 113.

[0043] In some embodiments, the end of the water tank 325 near the connecting seat 111 may be configured with a liquid filling port 3251, which can be used to inject coolant into the water tank 325. It will be understood that when not injecting liquid, the liquid filling port 3251 can be sealed by a sealing plug, which can be sealed and fixedly connected to the inner wall of the liquid filling port 3251 by means of a threaded connection or an interference fit. In addition, the end of the water tank 325 near the vertical pole 113 may be configured with a drain port 3252, which can be used to drain the coolant in the water tank 325. When the coolant in the water tank 325 does not need to be drained, the drain port 3252 can also be sealed by a sealing plug, which can be sealed and fixedly connected to the inner wall of the drain port 3252 by means of a threaded connection or an interference fit. The drain port 3252 is located near the bottom of the water tank 325 to facilitate the complete draining of the coolant in the water tank 325.

[0044] In some embodiments, a side wall of the water tank 325 facing the interior of the beam 112 may be in contact with the power battery 143 and may perform heat exchange with the power battery 143 to remove heat generated by the power battery 143 during operation, thereby achieving cooling and heat dissipation of the power battery 143 .

[0045] In some embodiments, the third heat exchange unit 323 may include a first sub-heat exchange unit 3231 and a second sub-heat exchange unit 3232. Both the first sub-heat exchange unit 3231 and the second sub-heat exchange unit 3232 may utilize an S-shaped copper tube structure. Both the first sub-heat exchange unit 3231 and the second sub-heat exchange unit 3232 are positioned flush against the inner wall of the crossbeam 112 and are disposed on either side of the water tank 325. Both the first sub-heat exchange unit 3231 and the second sub-heat exchange unit 3232 may contact the power battery 143 to exchange heat with the power battery 143 and thereby cool and dissipate heat from the power battery 143. In this embodiment, both the first sub-heat exchange unit 3231 and the second sub-heat exchange unit 3232 may be fixedly connected to the crossbeam 112 via tube fixing clips and bolts.

[0046] In other embodiments, the first sub-heat exchange portion 3231 and the second sub-heat exchange portion 3232 may also use heat exchange plates, and the heat exchange plates may be configured with S-shaped or Z-shaped flow channels for the coolant to pass through.

[0047] In some embodiments, the first heat exchange part 321 may be disposed in a fitting manner on the side of the driving member 141 facing the controller 142, and the side of the first heat exchange part 321 facing away from the driving member 141 may be in contact with the controller 142. Thus, the first heat exchange part 321 can perform heat exchange with the driving member 141 and the controller 142 respectively. In some embodiments, the first heat exchange part 321 may be an S-shaped copper tube structure, which can increase the contact area between the first heat exchange part 321 and the driving member 141 and the controller 142, and achieve rapid heat exchange. In addition, the first heat exchange part 321 can be fixed to the housing of the driving member 141 through pipe fixing buckles and bolts. The controller 142 can also be fixedly connected to the housing of the driving member 141 by means of bolt connection or the like.

[0048] In other embodiments, the first heat exchange part 321 may also be a heat exchange plate, and flow channels for coolant to pass through, such as S-shaped or Z-shaped channels, may be configured in the heat exchange plate.

[0049] In some embodiments, the second heat exchange part 322 may be disposed in a fitting manner on the side of the seat 151 facing the near-ground side 101, that is, the second heat exchange part 322 may be disposed in a fitting manner on the side of the seat 151 facing the connecting rod 152. The second heat exchange part 322 can perform heat exchange with the seat 151. Thus, in a hot environment, the temperature of the seat 151 can be reduced, providing a cooler riding condition for the user and improving the riding comfort of the user. In some embodiments, the second heat exchange part 322 may also be an S-shaped copper tube structure and can be fixed to the seat 151 through pipe fixing buckles and bolts.

[0050] In other embodiments, the second heat exchange part 322 may also be a heat exchange plate, and flow channels for coolant to pass through, such as S-shaped or Z-shaped channels, may be configured in the heat exchange plate.

[0051] In some embodiments, the fourth heat exchange part 324 may include a third sub-heat exchange part 3241 and a fourth sub-heat exchange part 3242. Both the third sub-heat exchange part 3241 and the fourth sub-heat exchange part 3242 may be linear copper tube structures and are both substantially parallel to the fork rod of the front fork 130. In the embodiment, the third sub-heat exchange part 3241 and the fourth sub-heat exchange part 3242 may be arranged in parallel and can both be fixed to the fork rod on the side of the front fork 130 close to the water pump 310 through pipe fixing buckles and bolts. During use, the fourth heat exchange part 324 can perform heat exchange with the external environment, and can dissipate the heat in the coolant to the external environment to achieve heat dissipation.

[0052] In other embodiments, the third sub-heat exchange part 3241 and the fourth sub-heat exchange part 3242 may also be spiral copper tube structures and are wound around the fork rod on the side of the front fork 130 close to the water pump 310.

[0053] In some embodiments, the water outlet 3253 of the water tank 325 may be disposed at one end of the water tank 325 close to the vertical rod 113, and a water outlet pipe 326 may be connected to the water outlet 3253 of the water tank 325. The water outlet pipe 326 may pass through the water tank 325 and protrude relative to one end of the water tank 325 close to the connection base 111. In the embodiment, one end of the water outlet pipe 326 away from the water outlet 3253 of the water tank 325 may be communicated with the third sub-heat exchange part 3241 through a second flexible adapter pipe 327. One end of the third sub-heat exchange part 3241 away from the second flexible adapter pipe 327 may be communicated with the input end of the water pump 310. The output end of the water pump 310 may be communicated with the fourth sub-heat exchange part 3242, and one end of the fourth sub-heat exchange part 3242 away from the water pump 310 may be communicated with the first sub-heat exchange part 3231 through another second flexible adapter pipe 327.

[0054] In the embodiments of the present application, the water outlet 3253 of the water tank 325 is disposed close to the bottom of the water tank 325, which may facilitate the water pump 310 to extract the coolant from the water tank 325. In addition, both ends of the fourth heat exchange part 324 close to the connection base 111 are communicated with the water outlet pipe 326 and the first sub-heat exchange part 3231 through the second flexible adapter pipe 327, which may avoid interfering with related operations such as the steering of the vehicle and facilitate the user to ride.

[0055] In some embodiments, one end of the first sub-heat exchange part 3231 away from the fourth heat exchange part 324 may be communicated with the input end of the first heat exchange part 321. The output end of the first heat exchange part 321 may be communicated with the input end of the second heat exchange part 322 through a first flexible adapter pipe 328. The output end of the second heat exchange part 322 may be communicated with the input end of the second sub-heat exchange part 3232 through another first flexible adapter pipe 328, and the output end of the second sub-heat exchange part 3232 may be communicated with the water return port 3254 of the water tank 325. In the embodiment, the two first flexible adapter pipes 328 may have sufficient allowance to satisfy that the seat 151 can be raised to the highest position relative to the vertical rod 113. That is, when the seat 151 is raised to the highest position relative to the beam frame assembly 110, the first flexible adapter pipe 328 may be in a natural straight state or a bent state.

[0056] During use, the user can inject coolant into the water tank 325 and fill each section of the pipeline of the cooling system 300 with the coolant. During the user's ride, the coolant can circulate under the action of the water pump 310 and successively pass through the third sub-heat exchange part 3241, the water pump 310, the fourth sub-heat exchange part 3242, the first sub-heat exchange part 3231, the first heat exchange part 321, the second heat exchange part 322, and the second sub-heat exchange part 3232 and then return to the water tank 325. When the coolant passes through the first heat exchange part 321, it can perform heat exchange with the driving member 141 and the controller 142 respectively to cool down the driving member 141 and the controller 142. When the coolant passes through the second heat exchange part 322, the coolant can perform heat exchange with the seat 151 to cool down the seat 151. When the coolant passes through the third heat exchange part 323 and the water tank 325, it can perform heat exchange with the power supply battery 143 to cool down the power supply battery 143. At the same time, when the coolant passes through the water tank 325, it can perform heat exchange with the external environment through the cross beam 112 to dissipate the heat in the coolant. When the coolant passes through the fourth heat exchange part 324, it can perform heat exchange with the external environment to dissipate the heat in the coolant to the outside, so that the coolant can perform heat exchange with the driving member 141, the controller 142, the power supply battery 143, and the seat 151 again.

[0057] In the vehicle provided in the embodiment of the present application, the cooling of the power supply battery 143, the driving member 141, and the controller 142 can be simultaneously achieved through the cooling system 300, reducing the heat accumulation at the positions of the power supply battery 143, the driving member 141, and the controller 142, reducing the risk of thermal runaway of the power supply battery 143, improving the use safety of the vehicle, and prolonging the service lives of the power supply battery 143, the driving member 141, and the controller 142. In addition, the cooling of the seat 151 can also be achieved through the cooling system 300 to improve the user's riding experience.
