Description

Technical Field

[0001] The present application relates to the automotive field, and in particular to an integrated water tank and a vehicle. Background Art

[0002] When the car is driving, it needs to use a water tank to cool the power system, such as the motor and engine. New energy vehicles mainly include pure electric vehicles and hybrid vehicles. Pure electric vehicles only have electric motors, while hybrid vehicles have electric motors and engines. In order to save space, the cars on the market currently integrate the engine water tank, motor water tank and washing pot. However, the engine water tank, motor water tank and washing pot are mainly fixed by welding and cannot be disassembled, so they cannot be switched between pure electric vehicles and hybrid vehicles, and the scope of application is relatively small. Utility Model Content

[0003] The purpose of the present application is to provide an integrated water tank and a vehicle, wherein the integrated water tank is easy to assemble, has a wider range of applications, and has lower costs.

[0004] The first aspect of the present application provides an integrated water tank, including a first tank body and a second tank body. The first tank body is provided with a first accommodating chamber, and the first accommodating chamber is used to accommodate engine coolant. The second tank body is used to accommodate washing liquid and motor coolant. The first tank body and the second tank body are detachably connected. The engine coolant in the first accommodating chamber is used to cool the engine, the washing liquid in the second tank body is used to wash the windshield of the vehicle, and the motor coolant in the second tank body is used to cool the motor. The hybrid model of the new energy vehicle has an engine and an electric motor, while the pure electric model only has an electric motor. If a hybrid model is developed, the hybrid vehicle needs to use engine coolant, washing liquid and motor coolant, so the entire integrated water tank must be used. If a pure electric model is developed, the pure electric vehicle only needs to use motor coolant and washing liquid. At this time, the first tank body containing the engine coolant is removed, and only the second tank body containing washing liquid and motor coolant needs to be used.

[0005] The integrated water tank provided in this embodiment reduces the space occupied by the first tank and the second tank in the vehicle by integrating the first tank and the second tank. The first tank and the second tank are detachably connected, so that the integrated water tank can be switched between hybrid vehicles and pure electric vehicles, and the application range of the integrated water tank is wider. When the manufacturer develops hybrid vehicles and pure electric vehicles at the same time, it only needs to develop a set of molds to produce integrated water tanks for hybrid vehicles and pure electric vehicles, which reduces the production cost.

[0006] In addition, the first box body and the second box body are detachably connected, which is more convenient to assemble than the welding and fixing connection method in the related art.

[0007] In some embodiments, the second housing includes a first sub-housing and a second sub-housing, the first sub-housing is provided with a second accommodating chamber, the second accommodating chamber is used to accommodate washing liquid. The second sub-housing is provided with a third accommodating chamber, the third accommodating chamber is used to accommodate motor cooling liquid. The first sub-housing and the second sub-housing are detachably connected, or the first sub-housing and the second sub-housing are integrally formed.

[0008] In some embodiments, the first sub-box includes a first outer surface and a second outer surface that are arranged opposite to each other, and the first sub-box also includes a third outer surface, the third outer surface is located between the first outer surface and the second outer surface, and the two ends of the third outer surface are respectively connected to the first outer surface and the second outer surface. The first box is connected to the first outer surface, and the second sub-box is connected to the second outer surface. Alternatively, the first box is connected to the first outer surface, and the second sub-box is connected to the third outer surface.

[0009] Generally, the temperature of the engine coolant after cooling the engine is higher than the temperature of the motor coolant after cooling the motor. The first box and the second sub-box are connected to the first sub-box, and the first box does not contact the second sub-box, so as to prevent the heat of the engine coolant with a higher temperature from being transferred to the motor coolant. The motor coolant can maintain a relatively low temperature, so that the motor coolant can better cool the motor. As a result, the motor has better performance and a longer life.

[0010] In some embodiments, the first box body is connected to the first outer surface, the second sub-box body is connected to the second outer surface, the first box body includes a first mounting surface, the first mounting surface is concavely provided with a card slot, and the first outer surface is convexly provided with a protrusion. Alternatively, the first mounting surface is convexly provided with a protrusion, and the first outer surface is concavely provided with a card slot. The protrusion is snapped into the card slot. Fixation is achieved by snapping the protrusion into the card slot, and assembly is convenient.

[0011] In some embodiments, there is a gap between the first mounting surface and the first outer surface. The second sub-box includes a second mounting surface, and the second mounting surface is located on a side of the second sub-box facing the second outer surface. A convex ring is convexly provided on the outer periphery of the second outer surface toward the second mounting surface, and the convex ring is fixed to the second mounting surface. Alternatively, a convex ring is convexly provided on the outer periphery of the second mounting surface toward the second outer surface, and the convex ring is fixed to the second outer surface.

[0012] By setting a gap between the first mounting surface and the first outer surface, and isolating the second outer surface from the second mounting surface by setting a convex ring, the heat of the liquids in the three cavities is prevented from being transferred to each other. The temperature of the engine coolant and the temperature of the motor coolant are prevented from rising, so that the motor and the engine can be better cooled, and the performance of the engine and the motor is better and the service life is longer.

[0013] In some embodiments, a plurality of first reinforcing plates are convexly disposed on the wall surface of the first accommodating cavity, and the plurality of first reinforcing plates are cross-arranged. By providing the first reinforcing plates, on the one hand, the structural strength of the first box body is better.

[0014] On the other hand, after the engine coolant flows from the first accommodating chamber through the engine cooling system to cool the engine, gas will be generated. At this time, the gas and the remaining engine coolant will flow back to the first accommodating chamber together. Since the temperature of the cavity wall of the first accommodating chamber is relatively low, when the high-temperature gas hits the cavity wall with a lower temperature, the gas will liquefy on the cavity wall, and the remaining engine coolant will continue to flow to the engine cooling system. That is, water-gas separation is achieved to prevent gas from interfering with the flow of the engine coolant, so that the engine coolant can flow smoothly to the engine cooling system.

[0015] Therefore, by providing the first reinforcing plate, the area of ​​the cavity wall that the gas can contact is larger, ensuring that more gas can be liquefied in the first receiving cavity, and achieving water-gas separation. At the same time, the gas liquefaction can form liquid. The larger the area of ​​the cavity wall, the faster the liquid increases, and the faster the engine coolant can be added to the first receiving cavity, ensuring that there is enough engine coolant in the first receiving cavity to flow to the engine cooling system, and the engine can be better cooled.

[0016] In some embodiments, the first reinforcing plates separate the first accommodating cavity into a plurality of first sub-cavities. The first reinforcing plate is provided with a first through hole, which penetrates both sides of the first reinforcing plate along the thickness direction to connect the plurality of first sub-cavities.

[0017] After the gas enters the first accommodating chamber, it can flow through the first through hole in the multiple first sub-cavities. At this time, the area of ​​the cavity wall that the gas can contact is larger, and more gas can be liquefied in the first accommodating chamber to ensure that all gas and liquid are separated. At the same time, the gas can be liquefied to form liquid. The larger the area of ​​the cavity wall, the faster the liquid increases, and the faster the engine coolant can be added to the first accommodating chamber, ensuring that the engine can be better cooled.

[0018] In some embodiments, a second reinforcing plate is convexly disposed on the wall surface of the third accommodating cavity. By providing the second reinforcing plate, on the one hand, the structural strength of the second sub-box is better.

[0019] On the other hand, after the motor coolant flows from the third accommodating chamber through the motor cooling system to cool the motor, gas will be generated. At this time, the gas and the remaining motor coolant will flow back to the third accommodating chamber together. Since the wall temperature of the third accommodating chamber is relatively low, when the higher temperature gas hits the lower temperature wall, the gas will liquefy on the wall, and the remaining motor coolant will continue to flow to the motor cooling system. That is, water-gas separation is achieved to prevent gas from interfering with the flow of motor coolant, so that the motor coolant can flow smoothly to the motor cooling system.

[0020] Therefore, by providing the second reinforcing plate, the area of ​​the cavity wall that the gas can contact is larger, ensuring that more gas can be liquefied in the third accommodating cavity to achieve water-gas separation. At the same time, the gas liquefaction can form liquid. The larger the area of ​​the cavity wall, the faster the liquid increases, and the faster the motor coolant can be added to the third accommodating cavity, ensuring that the motor can be better cooled.

[0021] In some embodiments, a plurality of second reinforcing plates are convexly disposed on the cavity wall of the third accommodating cavity, and the plurality of second reinforcing plates separate the third accommodating cavity into a plurality of third sub-cavities. The second reinforcing plate is provided with a second through hole, and the second through hole penetrates both sides of the second reinforcing plate along the thickness direction to connect the plurality of third sub-cavities.

[0022] After the gas enters the third accommodating chamber, it can flow through the second through hole in the multiple third sub-cavities. At this time, the area of ​​the cavity wall that the gas can contact is larger, and more gas can be liquefied in the third accommodating chamber to ensure that all gas and liquid are separated. At the same time, the gas liquefaction can form liquid. The larger the area of ​​the cavity wall, the faster the liquid increases, and the faster the motor coolant can be added to the third accommodating chamber to ensure that the motor can be better cooled.

[0023] In some embodiments, the first housing is provided with a first injection pipe, which is in communication with the first accommodating chamber. The first sub-housing is provided with a second injection pipe, which is in communication with the second accommodating chamber. The second sub-housing is provided with a third injection pipe, which is in communication with the third accommodating chamber. By providing the first injection pipe, the second injection pipe and the third injection pipe, it is convenient to add engine coolant, washing liquid and motor coolant.

[0024] In some embodiments, the first injection tube is disposed on the outer side of the first box body, and the first injection tube extends upward at an angle. The distance between the end of the first injection tube connected to the first box body and the bottom of the first box body is H1, and the distance between the end of the first injection tube connected to the first box body and the top of the first box body is H2, and H1>H2.

[0025] The third liquid injection pipe is arranged on the outer side surface of the second sub-box, and the third liquid injection pipe extends upward at an angle. The distance between the end of the third liquid injection pipe connected to the second sub-box and the bottom of the second sub-box is D1, and the distance between the end of the third liquid injection pipe connected to the second sub-box and the top of the second sub-box is D2, and D1>D2.

[0026] After the engine coolant and the motor coolant cool the engine and the motor respectively, the temperature rises and the volume increases. Therefore, when the first accommodating chamber and the third accommodating chamber are filled with the engine coolant and the motor coolant respectively, the entire cavity cannot be filled.

[0027] By respectively arranging the first liquid filling tube and the third liquid filling tube on the outer sides of the first box body and the second sub-box body, when the user fills the liquid, if the liquid level in the cavity exceeds the bottom of the first liquid filling tube and the third liquid filling tube, the liquid will overflow from the first liquid filling tube and the third liquid filling tube, and the user stops filling at this time.

[0028] A second aspect of the present application provides a vehicle, comprising the integrated water tank provided in the first aspect of the present application.

[0029] The integrated water tank provided in the embodiment of the present application reduces the space occupied by the first box body and the second box body in the vehicle by integrating the first box body and the second box body. In addition, the first box body and the second box body are detachably connected, so that the integrated water tank can be switched between hybrid vehicles and pure electric vehicles, and the application range of the integrated water tank is wider. When the manufacturer develops hybrid vehicles and pure electric vehicles at the same time, it only needs to develop a set of molds to produce integrated water tanks for hybrid vehicles and pure electric vehicles, which reduces the production cost. In addition, the first box body and the second box body are detachably connected, which is more convenient to assemble than the welding and fixing connection method of the related art.

For ease of understanding, the length direction of the integrated water tank is defined as the X-axis, the width direction is the Y-axis, and the height direction is the Z-axis, and the X-axis, Y-axis, and Z-axis are perpendicular to each other.

[0039] Please refer to Figure 1 , Figure 2 and Figure 3 The integrated water tank 1000 provided in the embodiment of the present application includes a first box body 100 and a second box body 200. The first box body 100 is provided with a first accommodating chamber 101, and the first accommodating chamber 101 is used to accommodate engine coolant. The second box body 200 is used to accommodate washing liquid and motor coolant. The first box body 100 and the second box body 200 are detachably connected.

[0040] Specifically, the first box body 100 includes a first upper end cover 102 and a first lower end cover 103. The end surface of the first upper end cover 102 facing the first lower end cover 103 is concavely provided with a first groove 104, and the end surface of the first lower end cover 103 facing the first upper end cover 102 is concavely provided with a second groove 105. The first groove 104 and the second groove 105 constitute a first accommodating cavity 101. The first upper end cover 102 and the first lower end cover 103 can be connected by hot plate welding at the notch position to assemble into the first box body 100.

[0041] The second housing 200 includes a first sub-housing 210 and a second sub-housing 260. The first sub-housing 210 is provided with a second accommodating chamber 201, and the second accommodating chamber 201 is used to accommodate washing liquid. The first sub-housing 210 includes a second upper end cover 211 and a second lower end cover 212. The end surface of the second upper end cover 211 facing the second lower end cover 212 is concavely provided with a third groove 213, and the end surface of the second lower end cover 212 facing the second upper end cover 211 is concavely provided with a fourth groove 214. The third groove 213 and the fourth groove 214 constitute the second accommodating chamber 201. The second upper end cover 211 and the second lower end cover 212 can be connected by hot plate welding at the notch position to assemble into the first sub-housing 210.

[0042] The second sub-box 260 is provided with a third accommodating chamber 202, and the third accommodating chamber 202 is used to accommodate the motor coolant. The second sub-box 260 includes a third upper end cover 261 and a third lower end cover 262, and the end surface of the third upper end cover 261 facing the third lower end cover 262 is concavely provided with a fifth groove 263, and the end surface of the third lower end cover 262 facing the third upper end cover 261 is concavely provided with a sixth groove 264, and the fifth groove 263 and the sixth groove 264 constitute the third accommodating chamber 202, and the third upper end cover 261 and the third lower end cover 262 can be connected by hot plate welding at the notch position to assemble into the second sub-box 260.

[0043] After the first box 100, the first sub-box 210 and the second sub-box 260 are assembled separately, the first box 100, the first sub-box 210 and the second sub-box 260 are assembled into an integrated water tank 1000. Specifically, the first sub-box 210 and the second sub-box 260 are connected and assembled into the second box 200, and the first box 100 can be detachably connected to the first sub-box 210, and can also be detachably connected to the second sub-box 260.

[0044] The integrated water tank 1000 provided in this embodiment is used in a vehicle, the first accommodating chamber 101 contains engine coolant, the first box body 100 is provided with a first infusion port 106 and a first inlet port 107, and the first infusion port 106 and the first inlet port 107 are both connected to the first accommodating chamber 101. Under the action of the water pump, the engine coolant in the first accommodating chamber 101 flows from the first infusion port 106 to the engine cooling system to cool the engine. After cooling the engine, the engine coolant enters the first accommodating chamber 101 from the first inlet port 107, and the engine coolant circulates between the first accommodating chamber 101 and the engine cooling system, so that the engine can be continuously cooled.

[0045] Please refer to Figure 3 The second accommodating chamber 201 contains washing liquid, and a mounting groove 215 for a washing motor is provided at the bottom of the first sub-box 210. The mounting groove 215 is formed by the bottom surface of the first sub-box 210 and the cavity bottom surface being concavely arranged toward the second accommodating chamber 201. The washing motor is fixed in the mounting groove, and the washing liquid in the second accommodating chamber 201 can be sprayed onto the windshield under the action of the washing motor to wash the windshield.

[0046] Continue to refer Figure 1 , Figure 2 and Figure 3 The third accommodating chamber 202 contains the motor coolant, and the second sub-box 260 is provided with a second infusion port 265 and a second inlet port 266, and the second infusion port 265 and the second inlet port 266 are both connected to the third accommodating chamber 202. Under the action of the water pump, the motor coolant in the third accommodating chamber 202 flows from the second infusion port 265 to the motor cooling system to cool the motor, and the motor coolant after cooling the motor enters the third accommodating chamber 202 from the second inlet port 266, and the motor coolant circulates between the third accommodating chamber 202 and the motor cooling system, so that the motor can be continuously cooled.

[0047] There are two types of new energy vehicles on the market, namely hybrid vehicles and pure electric vehicles. Hybrid vehicles have an engine and an electric motor, while pure electric vehicles only have an electric motor. If a hybrid vehicle is developed, the hybrid vehicle needs to use engine coolant, washing liquid and motor coolant, so the entire integrated water tank 1000 must be used. If a pure electric vehicle is developed, the pure electric vehicle only needs to use motor coolant and washing liquid. At this time, the first box 100 containing the engine coolant can be removed, and only the second box 200 containing washing liquid and motor coolant can be used.

[0048] By integrating the first box body 100 and the second box body 200, the space occupied by the first box body 100 and the second box body 200 in the vehicle is reduced. Moreover, the first box body 100 and the second box body 200 are detachably connected, so that the integrated water tank 1000 can be switched between hybrid vehicles and pure electric vehicles, and the integrated water tank 1000 has a wider range of applications. When the manufacturer develops hybrid vehicles and pure electric vehicles at the same time, only one set of molds needs to be developed to produce the integrated water tank 1000 for hybrid vehicles and pure electric vehicles, which reduces the production cost. In addition, the first box body 100 and the second box body 200 are detachably connected, which is more convenient to assemble than the welding and fixing connection method of the related art, and if one of the boxes is damaged, only the damaged box needs to be disassembled and replaced, which is convenient for maintenance and has lower maintenance costs.

[0049] In some embodiments, the first sub-box 210 and the second sub-box 260 are detachably connected. Specifically, the first sub-box 210 and the second sub-box 260 can be connected by bolts or fixed by clamping. It can be understood that the three boxes are fixed to each other, the three boxes are fixed more firmly, the integrated water tank 1000 has higher structural strength and longer life, and is easy to disassemble and repair.

[0050] In some embodiments, the first sub-box 210 and the second sub-box 260 can be integrally formed, that is, the second upper end cover 211 and the third upper end cover 261 can be integrally injection molded into one component, the second lower end cover 212 and the third lower end cover 262 can be integrally injection molded into one component, and finally the two components are connected by hot plate welding to form the second box 200. By integrally forming the first sub-box 210 and the second sub-box 260, the assembly process is reduced, thereby improving work efficiency.

[0051] In some embodiments, please refer to Figure 1 and Figure 2 The first sub-box 210 includes a first outer surface 216 and a second outer surface 218 that are oppositely arranged. The first sub-box 210 also includes a third outer surface 228, which is located between the first outer surface 216 and the second outer surface 218, and the two ends of the third outer surface 228 are respectively connected to the first outer surface 216 and the second outer surface 218.

[0052] The first box 100 is connected to the first outer surface 216, and the second sub-box 260 is connected to the second outer surface 218, that is, the first box 100, the first sub-box 210 and the second sub-box 260 are connected in a straight line. Alternatively, the first box 100 is connected to the first outer surface 216, and the second sub-box 260 is connected to the third outer surface 228, that is, the first box 100, the first sub-box 210 and the second sub-box 260 are connected in an L-shape. In this embodiment, the positions of the first outer surface 216, the second outer surface 218 and the third outer surface 228 are not limited to Figure 1 and Figure 2 Position shown.

[0053] Generally, the temperature of the engine coolant after cooling the engine is higher than the temperature of the motor coolant after cooling the motor. In this embodiment, the first box 100 and the second sub-box 260 are connected to the first sub-box 210, and the first box 100 is not in direct contact with the second sub-box 260, so as to prevent the heat of the engine coolant with a higher temperature from being transferred to the motor coolant. The motor coolant can maintain a relatively low temperature, so that the motor coolant can better cool the motor. As a result, the motor has better performance and a longer life.

[0054] At the same time, this design can also prevent the heat of the motor coolant from being transferred to the engine coolant, so that the engine coolant has a relatively low temperature. The engine coolant can better cool the engine, resulting in better engine performance and longer life.

[0055] In some embodiments, please refer to Figure 2 , Figure 4 and Figure 5 , the first box body 100 is connected to the first outer surface 216, and the second sub-box body 260 is connected to the second outer surface 218. The first box body 100 includes a first mounting surface 108, the first mounting surface 108 is concavely provided with a card slot 109, and the first outer surface 216 is convexly provided with a protrusion 217. Alternatively, the first mounting surface 108 is convexly provided with a protrusion 217, and the first outer surface 216 is concavely provided with a card slot 109. The first mounting surface 108 and the first outer surface 216 are opposite, and the protrusion 217 is inserted into the card slot 109.

[0056] In this embodiment, the card slot 109 is recessed in the first mounting surface 108, and the protrusion 217 is protruded on the first outer surface 216. Specifically, the first box body 100 is provided with four card slots 109, two of which are provided on the outer side of the first upper end cover 102, and the other two card slots 109 are provided on the outer side of the first lower end cover 103. Correspondingly, the first sub-box body 210 is provided with four protrusions 217, two of which are provided on the outer side of the second upper end cover 211, and the other two protrusions 217 are provided on the outer side of the second lower end cover 212.

[0057] The first box 100 and the first sub-box 210 are fixed by the protrusion 217 being snapped into the slot 109, that is, connected by snapping. No additional mounting parts and mounting equipment are required when assembling the first box 100 and the first sub-box 210, which is convenient to assemble and has lower production cost.

[0058] In other embodiments, the positions of the protrusion 217 and the slot 109 can be interchanged, that is, the protrusion 217 is convexly disposed on the first mounting surface 108 , and the slot 109 is concavely disposed on the first outer surface 216 .

[0059] In some embodiments, please refer to Figure 2 and Figure 3 , there is a gap between the first mounting surface 108 and the first outer surface 216. The first sub-box 210 includes a second outer surface 218, and the second outer surface 218 and the first outer surface 216 are arranged opposite to each other. The second sub-box 260 includes a second mounting surface 267, and the second mounting surface 267 is located on the side of the second sub-box 260 facing the second outer surface 218. A convex ring 219 is protruded from the outer periphery of the second outer surface 218 in the direction of the second mounting surface 267, and the convex ring 219 is fixed to the second mounting surface 267; or, a convex ring 219 is protruded from the outer periphery of the second mounting surface 267 in the direction of the second outer surface 218, and the convex ring 219 is fixed to the second outer surface 218.

[0060] Specifically, the dimension of the protrusion 217 along the X-axis direction is greater than the dimension of the slot 109 along the X-axis direction, so that the protrusion 217 cannot be fully inserted into the slot 109 , and a gap is formed between the first mounting surface 108 and the first outer surface 216 .

[0061] In this embodiment, the second outer surface 218 is opposite to the second mounting surface 267, and the convex ring 219 is convexly arranged on the second outer surface 218. The side of the convex ring 219 facing away from the second outer surface 218 is fixed to the second mounting surface 267. Exemplarily, the convex ring 219 is fixed to the second mounting surface 267 by welding. By arranging the convex ring 219 on the second outer surface 218 and fixing the convex ring 219 to the second mounting surface 267, a gap is formed between the second outer surface 218 and the second mounting surface 267.

[0062] By setting a gap between the first mounting surface 108 and the first outer surface 216, and setting a gap between the second outer surface 218 and the second mounting surface 267, the heat of the liquids in the three cavities is prevented from being transferred to each other. The temperature rise of the engine coolant and the motor coolant is avoided, so that the motor and the engine can be better cooled, and the performance of the engine and the motor is better and the service life is longer.

[0063] In other embodiments, a protruding ring 219 is protruded from the outer periphery of the second mounting surface 267 toward the second outer surface 218 , and the protruding ring 219 is fixed to the second outer surface 218 .

[0064] In some embodiments, please refer to Figure 2 The cavity wall of the first accommodating cavity 101 is provided with a plurality of first reinforcing plates 110, and the plurality of first reinforcing plates 110 are cross-arranged. Specifically, the first reinforcing plate 110 includes a first sub-plate 111 and a second sub-plate 112, and the plurality of first sub-plates 111 are arranged in the first groove 104, and the plurality of first sub-plates 111 are cross-arranged, and the plurality of first sub-plates 111 and the first upper end cover 102 are integrally injection molded. The plurality of second sub-plates 112 are arranged in the second groove 105, and the plurality of second sub-plates 112 are cross-arranged, and the plurality of second sub-plates 112 and the first lower end cover 103 are integrally injection molded.

[0065] After the first upper end cover 102 and the first lower end cover 103 are assembled, it is necessary to ensure that each area of ​​the first accommodating cavity 101 is in a connected state, and to ensure that the engine coolant and gas can flow to each area of ​​the first accommodating cavity 101. For example, along the Z-axis direction, the height of the first sub-plate 111 is lower than the depth of the first groove 104, and the height of the second sub-plate 112 is lower than the depth of the second groove 105, so that there is a gap between the first sub-plate 111 and the second sub-plate 112, and the areas on both sides of the first reinforcing plate 110 are connected. Alternatively, the first sub-plate 111 and the second sub-plate 112 are staggered, so that each area of ​​the first accommodating cavity 101 can also be connected.

[0066] The integrated water tank 1000 provided in this embodiment is provided with a first reinforcing plate 110. On the one hand, the structural strength of the first box body 100 is better. On the other hand, after the engine coolant flows from the first accommodating chamber 101 through the engine cooling system to cool the engine, gas will be generated. At this time, the gas and the remaining engine coolant will flow back to the first accommodating chamber 101 together. Since the cavity wall temperature of the first accommodating chamber 101 is relatively low, when the higher temperature gas hits the cavity wall surface with a lower temperature, the gas will be adsorbed on the cavity wall surface and liquefied, while the remaining engine coolant continues to flow to the engine cooling system. That is, water-gas separation is achieved to prevent gas from interfering with the flow of engine coolant, so that the engine coolant can flow smoothly to the engine cooling system.

[0067] Therefore, by providing a plurality of first reinforcing plates 110, the area of ​​the cavity wall that the gas can contact is larger, ensuring that more gas can be liquefied in the first accommodating cavity 101 to achieve water-gas separation. At the same time, the gas liquefaction can form liquid, and the larger the area of ​​the cavity wall, the faster the liquid increases, and the faster the engine coolant can be added to the first accommodating cavity 101, ensuring that the engine can be better cooled.

[0068] In some embodiments, please refer to Figure 2 The first reinforcing plates 110 separate the first accommodating cavity 101 into a plurality of first sub-cavities 113. The first reinforcing plates 110 are provided with first through holes 114, which penetrate both sides of the first reinforcing plates 110 in the thickness direction to connect the plurality of first sub-cavities 113.

[0069] Specifically, after the first upper end cover 102 and the first lower end cover 103 are assembled, the plurality of first sub-plates 111 and the plurality of second sub-plates 112 are fitted and arranged in a one-to-one correspondence, so that the first accommodating cavity 101 is isolated into a plurality of first sub-cavities 113 .

[0070] In this embodiment, a portion of the first through hole 114 may be disposed on the first sub-board 111, and another portion of the first through hole 114 may be disposed on the second sub-board 112. In other embodiments, the first through hole 114 may be disposed only on the first sub-board 111 or only on the second sub-board 112.

[0071] After the gas and liquid enter the first accommodating chamber 101, they can flow through the first through hole 114 in the plurality of first sub-cavities 113. At this time, the area of ​​the cavity wall that the gas can contact is larger, ensuring that all the gas can be liquefied in the first accommodating chamber 101, so that the gas and liquid are completely separated. At the same time, the gas can be liquefied to form liquid. The larger the area of ​​the cavity wall, the faster the liquid increases, and the faster the engine coolant can be added to the first accommodating chamber 101. This ensures that the engine can be better cooled.

[0072] In some embodiments, please refer to Figure 2 The second reinforcing plate 220 is convexly provided on the wall surface of the third accommodating cavity 202. Specifically, the second reinforcing plate 220 includes a third sub-plate 221 and a fourth sub-plate 222. The third sub-plate 221 is disposed in the fifth groove 263. The third sub-plate 221 and the third upper end cover 261 are integrally injection molded. The fourth sub-plate 222 is disposed in the sixth groove 264. The fourth sub-plate 222 and the third lower end cover 262 are integrally injection molded.

[0073] After the third upper end cover 261 and the third lower end cover 262 are assembled, it is necessary to ensure that each area of ​​the third accommodating chamber 202 is in a connected state, and to ensure that the motor coolant and gas can flow to each area of ​​the third accommodating chamber 202. For example, along the Z-axis direction, the height of the third sub-plate 221 is lower than the depth of the fifth groove 263, and the height of the fourth sub-plate 222 is lower than the depth of the sixth groove 264, so that there is a gap between the third sub-plate 221 and the fourth sub-plate 222. Alternatively, the third sub-plate 221 and the fourth sub-plate 222 can also be staggered. Both methods can achieve the connection of each area of ​​the third accommodating chamber 202.

[0074] By providing the second reinforcing plate 220, on the one hand, the structural strength of the second sub-box 260 is better. On the other hand, after the motor coolant flows from the third accommodating chamber 202 through the motor cooling system to cool the motor, gas will be generated. At this time, the gas and the remaining motor coolant will flow back to the third accommodating chamber 202. Since the cavity wall temperature of the third accommodating chamber 202 is relatively low, when the higher temperature gas hits the lower temperature cavity wall, the gas will be adsorbed on the cavity wall and liquefied, and the remaining motor coolant will continue to flow to the motor cooling system. That is, water-gas separation is achieved to prevent gas from interfering with the flow of motor coolant, so that the motor coolant can flow smoothly to the motor cooling system.

[0075] Therefore, by providing the second reinforcing plate 220, the area of ​​the cavity wall that the gas can contact is larger, ensuring that more gas can be liquefied in the third accommodating cavity 202 to achieve water-gas separation. At the same time, the gas liquefaction can form liquid, and the larger the area of ​​the cavity wall, the faster the liquid increases, and the faster the motor coolant can be added to the third accommodating cavity 202, ensuring that the motor can be better cooled.

[0076] In some embodiments, please refer to Figure 2 A plurality of second reinforcing plates 220 are convexly disposed on the cavity wall of the third accommodating cavity 202, and the plurality of second reinforcing plates 220 separate the third accommodating cavity 202 into a plurality of third sub-cavities 223. The second reinforcing plates 220 are provided with second through holes 224, and the second through holes 224 penetrate through both sides of the second reinforcing plates 220 in the thickness direction to connect the plurality of third sub-cavities 223.

[0077] Specifically, after the third upper end cover 261 and the third lower end cover 262 are assembled, the plurality of third sub-plates 221 and the plurality of fourth sub-plates 222 are fitted and arranged in a one-to-one correspondence, so that the third accommodating cavity 202 is isolated into a plurality of third sub-cavities 223 .

[0078] In this embodiment, a portion of the second through hole 224 is disposed on the third sub-board 221, and another portion of the second through hole 224 is disposed on the fourth sub-board 222. In other embodiments, the second through hole 224 may be disposed only on the third sub-board 221 or only on the fourth sub-board 222.

[0079] By providing a plurality of second reinforcing plates 220, on the one hand, the structural strength of the second sub-box 260 is better. On the other hand, after the gas enters the third accommodating chamber 202, it can flow in the plurality of third sub-cavities 223 through the second through hole 224. At this time, the area of ​​the cavity wall that the gas can contact is larger, ensuring that all the gas can be liquefied in the third accommodating chamber 202, so that the gas and the liquid are completely separated. At the same time, the liquefied gas can form liquid. The larger the area of ​​the cavity wall, the faster the liquid increases, and the faster the motor coolant can be added to the third accommodating chamber 202, ensuring that the motor can be better cooled.

[0080] In some embodiments, please refer to Figure 6 The first box 100 is further provided with a first injection pipe 115, which is disposed on the outer side of the first box 100 and communicates with the first accommodating chamber 101. The first injection pipe 115 extends obliquely upward, and a distance H1 between the end of the first injection pipe 115 connected to the first box 100 and the bottom of the first box 100 is greater than a distance H2 between the end of the first injection pipe 115 connected to the first box 100 and the top of the first box 100.

[0081] The first sub-box 210 is provided with a second liquid injection pipe 225 . The second liquid injection pipe 225 is disposed on the top of the first sub-box 210 . The second liquid injection pipe 225 is communicated with the second accommodating chamber 201 .

[0082] The second sub-box 260 is provided with a third liquid injection tube 268, and the third liquid injection tube 268 is arranged on the outer side surface of the second sub-box 260, the third liquid injection tube 268 is connected to the third accommodating chamber 202, and the third liquid injection tube 268 extends upward at an angle. The distance D1 between the end of the third liquid injection tube 268 connected to the second sub-box 260 and the bottom of the second sub-box 260 is greater than the distance D2 between the end of the third liquid injection tube 268 connected to the second sub-box 260 and the top of the second sub-box 260.

[0083] After the engine coolant and the motor coolant cool the engine and the motor respectively, the temperature rises and the volume increases. Therefore, when the first accommodating chamber 101 and the third accommodating chamber 202 are filled with the engine coolant and the motor coolant respectively, the entire chamber cannot be filled.

[0084] Specifically, the connection position of the first injection pipe 115 and the first box body 100 is located at the position of the liquid level when the engine coolant in the first accommodating chamber 101 is filled to the maximum. The connection position of the third injection pipe 268 and the second sub-box body 260 is located at the position of the liquid level when the motor coolant in the third accommodating chamber 202 is filled to the maximum.

[0085] The connection position between the first injection pipe 115 and the first box body 100 is at a certain distance from the top surface of the first accommodating chamber 101 , and the connection position between the third injection pipe 268 and the second sub-box body 260 is at a certain distance from the top surface of the third accommodating chamber 202 .

[0086] When the user fills the engine coolant, if the liquid level in the cavity exceeds the connection position between the first injection pipe 115 and the first box 100, the liquid will overflow from the first injection pipe 115, and the user stops filling. When the user fills the motor coolant, if the liquid level exceeds the connection position between the third injection pipe 268 and the second sub-box 260, the liquid will overflow from the third injection pipe 268, and the user stops filling.

[0087] Therefore, by arranging the first injection pipe 115 and the third injection pipe 268 on the outer side of the first housing 100 and the second sub-housing 260 respectively, and the connection position of the first injection pipe 115 and the first housing 100 is at a certain distance from the top surface of the first accommodating chamber 101, and the connection position of the third injection pipe 268 and the second sub-housing 260 is at a certain distance from the top surface of the third accommodating chamber 202, the user can be prevented from filling the first accommodating chamber 101 and the third accommodating chamber 202.

[0088] In some embodiments, please refer to Figure 1 The first box 100, the first sub-box 210 and the second sub-box 260 are made of transparent or translucent materials; the outer side of the first box 100 is provided with a first liquid level line 116 and a second liquid level line 117. The first liquid level line 116 is the highest liquid level line for filling, and the liquid level when the engine coolant is filled to the maximum is flush with the first liquid level line 116. The second liquid level line 117 is the lowest liquid level line for filling, and the liquid level when the engine coolant is filled to the minimum is flush with the second liquid level line 117.

[0089] Along the Z-axis direction, the first liquid level line 116 is located between the top surface of the first accommodating chamber 101 and the second liquid level line 117, and the first liquid level line 116 is spaced apart from the top surface of the first accommodating chamber 101. The first liquid level line 116 and the second liquid level line 117 are spaced apart.

[0090] In this embodiment, the first liquid level line 116 and the second liquid level line 117 are bosses on the outer side of the first box body 100. In other embodiments, lines may also be printed as the first liquid level line 116 and the second liquid level line 117.

[0091] The outer side of the first sub-box 210 is provided with a third liquid level line 226 and a fourth liquid level line 227. The third liquid level line 226 is the highest liquid level line for filling, and the liquid level when the motor coolant is filled to the maximum is flush with the third liquid level line 226. The fourth liquid level line 227 is the lowest liquid level line for filling, and the liquid level when the motor coolant is filled to the minimum is flush with the fourth liquid level line 227.

[0092] Along the Z-axis direction, the third liquid level line 226 is located between the cavity top surface of the third accommodating cavity 202 and the fourth liquid level line 227 , the third liquid level line 226 keeps a distance from the cavity top surface of the third accommodating cavity 202 , and the third liquid level line 226 and the fourth liquid level line 227 are arranged at intervals.

[0093] In this embodiment, the third liquid level line 226 and the fourth liquid level line 227 are bosses on the outer side of the first sub-box 210. In other embodiments, the third liquid level line 226 and the fourth liquid level line 227 may also be printed lines.

[0094] By setting the first box body 100, the first sub-box body 210 and the second sub-box body 260 to a transparent or translucent state, it is convenient for the user to judge whether the liquid needs to be replenished. In addition, when the user fills the engine coolant, the liquid level of the engine coolant shall not exceed the first liquid level line 116, and shall not be lower than the second liquid level line 117. When the user fills the motor coolant, the liquid level of the motor coolant shall not exceed the third liquid level line 226, and shall not be lower than the fourth liquid level line 227. By setting the first liquid level line 116, the second liquid level line 117, the third liquid level line 226 and the fourth liquid level line 227, it is convenient for the user to add the engine coolant and the motor coolant.

[0095] In some embodiments, a first sensor is provided on the outside of the first box body 100, and the first sensor is used to detect the content of engine coolant in the first accommodating cavity 101; a second sensor is provided on the outside of the second sub-box body 260, and the second sensor is used to detect the content of motor coolant in the third accommodating cavity 202.

[0096] By providing the first sensor and the second sensor, it is convenient for the user to determine whether the engine coolant and the motor coolant need to be replenished.
