Description

TECHNICAL FIELD

[0002] In existing vehicles and other vehicles, a liquid supply system is usually used for cooling, washing, lubricating, hydraulic pressure, conveying and other functions of corresponding modules, and its core components include a water pump and a liquid storage pot. In traditional design, the water pump and the liquid storage pot are usually arranged separately and connected through external pipelines. Although this method can meet the basic use requirements, it has some problems in actual application.

[0003] Firstly, since the water pump and the liquid storage pot are structurally independent of each other, they occupy more space and have a larger overall weight, which makes it difficult to meet the lightweight and compact requirements of vehicles such as flying cars that have extremely strict requirements on weight and space. Secondly, since additional pipelines are needed for connection, not only does it increase the complexity of the system, but it also poses a risk of liquid leakage. In addition, the connection stability and reliability between the water pump and the liquid storage pot are easily affected by adverse conditions when facing complex working conditions (such as the flight state of a flying car).

With the development of emerging vehicles such as flying cars, there is an urgent need for a lighter, more compact, and more reliable liquid supply system to meet the strict requirements on weight and performance.

[0047] In the existing vehicles and other transportation tools, a liquid supply system is usually used for cooling, washing, lubricating, hydraulic pressure, conveying and other functions of corresponding modules, and the core components thereof include a water pump and a liquid storage pot. In the traditional design, the water pump and the liquid storage pot are usually arranged separately and connected through external pipelines. Although this method can meet the basic use requirements, there are some problems in actual application.

[0048] Firstly, since the water pump and the liquid storage pot are independent of each other in structure, they occupy more space and have a larger overall weight, which is difficult to meet the lightweight and compact requirements of a flying car and other vehicles with strict requirements on weight and space. Secondly, the additional pipeline for connection not only increases the complexity of the system, but also has the risk of liquid leakage. In addition, the connection stability and reliability between the water pump and the liquid storage pot are easily affected by adverse conditions, such as the flight state of a flying car.

[0049] In summary, the existing liquid supply system has certain deficiencies in integration, lightweight, and adaptation to the needs of high-performance vehicles. With the development of emerging vehicles such as flying cars, there is an urgent need for a lighter, more compact, and more reliable liquid supply system to meet the strict requirements on weight and performance.

[0050] To solve the above problems, the present application provides a pump-liquid tank assembly, which aims to integrate the water pump and the liquid storage pot in one, so as to reduce the number of parts, reduce the overall weight, increase the compactness of the structure, and improve the stability and reliability of the system.

[0051] Please refer to Figure 1 and Figure 2 , an embodiment of the present application provides a pump-liquid tank assembly, which comprises:

[0052] a liquid storage tank 1, the liquid storage tank 1 is provided with a liquid inlet end 111, a liquid outlet end 112, and a pump body connecting port 113, the liquid inlet end 111, the liquid outlet end 112, and the pump body connecting port 113 are in communication with the inner cavity of the liquid storage tank 1;

[0053] a pump body shell 2, the pump body shell 2 covers the pump body connecting port 113, so that the inner cavity of the liquid storage tank 1 forms a closed chamber 14;

[0054] a separation sleeve 3, the separation sleeve 3 is sealingly connected to one side of the pump body shell 2 facing the liquid storage tank 1, so as to divide the closed chamber 14 into a liquid immersion area 141 and a non-liquid immersion area 142; the liquid immersion area 141 is in communication with the liquid inlet end 111 and the liquid outlet end 112, and the liquid inlet end 111 is used to supply working liquid to the liquid immersion area 141;

[0055] a turbine 4, the turbine 4 is rotatably connected to one side of the separation sleeve 3 located in the liquid immersion area 141; the turbine 4 is used to deliver the working liquid in the liquid immersion area 141 to the liquid outlet end 112 during rotation.

[0056] In this embodiment, the liquid storage tank 1 can be provided as an integrated structure or a split structure, which is not limited here. As an example, when the liquid storage tank 1 adopts a split structure, as shown in Figure 1As shown, the liquid storage tank 1 comprises a first tank body 11, a second tank body 12 and a cover body 13, the first tank body 11 has an upper opening and a lower opening, the lower opening of the first tank body 11 constitutes a pump body connecting port 113, a liquid inlet end 111 and a liquid outlet end 112 are arranged on the first tank body 11 and communicate with the inner cavity of the first tank body 11; the second tank body 12 also has an upper opening and a lower opening, the lower opening of the second tank body 12 is butted with the upper opening of the first tank body 11, and the cover body 13 covers the upper opening of the second tank body 12; a mounting bracket 121 is arranged on the second tank body 12, and the mounting bracket 121 is used to be connected with the corresponding structure on the vehicle to realize the mounting and fixing of the pump liquid tank assembly on the vehicle.

[0057] The pump body shell 2 can be connected to the liquid storage tank 1 by locking, buckling, welding and the like, and covers the pump body connecting port 113, so that the upper side wall of the pump body shell 2 and the inner cavity wall of the liquid storage tank 1 jointly enclose a closed cavity 14.

[0058] The isolation sleeve 3 can be sealingly connected to the upper side wall of the pump body shell 2 through a corresponding sealing element, and the isolation sleeve 3, the sealing element and the pump body shell 2 should be able to enclose a sealed area in the above-mentioned closed cavity 14, which constitutes a non-immersed liquid area 142 (also referred to as a dry area), and the other areas in the above-mentioned closed cavity 14 except the non-immersed liquid area 142 constitute an immersed liquid area 141 (also referred to as a wet area); since the liquid cannot flow between the immersed liquid area 141 and the non-immersed liquid area 142, when the working liquid is supplied into the inner cavity of the liquid storage tank 1 through the liquid inlet end 111 (i.e. into the above-mentioned closed cavity 14), it can be ensured that the working liquid only flows in the immersed liquid area 141 and does not enter the non-immersed liquid area 142. Based on the above-mentioned arrangement, important devices and modules (such as the drive assembly of the turbine 4 and the control module) in the pump liquid tank assembly which are not waterproof can be installed in the non-immersed liquid area 142, so that the damage of these devices and modules due to contact with liquid can be avoided. The working liquid can include liquids for realizing cooling, washing, lubrication, hydraulic pressure, conveying and the like, such as cooling liquid, cleaning agent, lubricating oil, hydraulic oil and the like.

[0059] The turbine 4 can realize the transfer of the working liquid based on centrifugal action, axial flow action, etc. When the turbine 4 is centrifugal, the working liquid in the liquid immersion area 141 will be thrown to the periphery under the rotation of the turbine 4 after entering the turbine 4. The working liquid can obtain kinetic energy by the centrifugal action of the turbine 4 in the process, and the working liquid can be output outward by the liquid outlet end 112 under a certain kinetic energy. When the turbine 4 is axial, the working liquid in the liquid immersion area 141 will enter along the axial direction of the turbine 4 and flow out along the axial direction of the turbine 4. In this process, the rotation of the turbine 4 will make the working liquid obtain kinetic energy in the axial direction, so that the working liquid can be output outward by the liquid outlet end 112 under a certain kinetic energy. In actual application, it is only necessary to ensure that the turbine 4 can provide kinetic energy for the working liquid in the liquid immersion area 141 when rotating and transfer the working liquid to the liquid outlet end 112, and ensure that the liquid outlet end 112 stops outputting the working liquid outward when the turbine 4 does not rotate. The specific form of the turbine 4 is not limited here. The working liquid output outward through the liquid outlet end 112 can be used for cooling, washing, lubricating, hydraulic pressure, conveying and other functions of the corresponding components and modules on the vehicle.

[0060] As can be seen, the pump liquid tank assembly provided in the embodiment integrates the water pump and the liquid storage pot in the traditional design in a split type connection, forms an integrated structure including the liquid storage tank 1, the pump body shell 2, the isolation sleeve 3 and the turbine 4, cancels the external pipeline and other connecting devices, significantly improves the compactness of the structure, reduces the space occupation, and effectively reduces the overall weight. Therefore, the pump liquid tank assembly can better meet the needs of the flying car and other vehicles with extremely strict requirements on weight and space. At the same time, the integrated structure can reduce the complexity of the system, reduce the risk of liquid leakage, and better maintain the reliability and stability of the system under complex working conditions.

[0061] Optionally, referring to Figures 1 to 3 , the side of the pump body shell 2 facing the liquid storage tank 1 is a sealing surface 21, and the sealing surface 21 is provided with a first recessed cavity 22; the isolation sleeve 3 has a first column segment 31 and a second column segment 32 connected in sequence, and the cross-sectional area of the first column segment 31 is greater than that of the second column segment 32, and the second column segment 32 is accommodated in the first recessed cavity 22.

[0062] The pump liquid tank assembly further comprises a sealing ring 5, the sealing ring 5 is arranged around the second column segment 32, and the sealing ring 5 is attached between the first column segment 31 and the sealing surface 21; a sealing area formed by the sealing ring 5, the outer side wall of the second column segment 32 and the cavity wall of the first recessed cavity 22 constitutes a non-liquid immersion area 142.

[0063] Specifically, with Figure 2The upper side of the pump body shell 2 is a sealing surface 21, the first column segment 31 and the second column segment 32 are sequentially connected along a vertical axis, the first column segment 31 is located above the second column segment 32, the cross-sectional area of the first column segment 31 is greater than that of the first recessed cavity 22, and the cross-sectional area of the second column segment 32 is smaller than that of the first recessed cavity 22; under the action of gravity or other external forces, the lower end surface of the first column segment 31 presses the sealing ring 5 against the sealing surface 21 to form a sealing effect, at this time, there is a preset interval between the outer column surface of the second column segment 32 and the vertical side wall of the first recessed cavity 22, and between the lower end surface of the second column segment 32 and the bottom wall of the first recessed cavity 22, and the sealing area formed by the preset interval constitutes a non-immersion area 142.

[0064] Through the cooperation between the second column segment 32 and the first recessed cavity 22, the lower part of the isolation sleeve 3 is accommodated in the pump body shell 2, which can avoid the isolation sleeve 3 from excessively protruding from the surface of the pump body shell 2, so as to further compress the space occupied by the pump liquid tank assembly; and the non-immersion area 142 formed between the second column segment 32 and the first recessed cavity 22 has a vertical annular area located at the upper part (i.e., the interval area between the outer column surface of the second column segment 32 and the vertical side wall of the first recessed cavity 22) and a columnar area located at the lower part (i.e., the interval area between the lower end surface of the second column segment 32 and the bottom wall of the first recessed cavity 22), which can better adapt to the installation requirements of devices and modules of different size specifications in the non-immersion area 142. In addition, based on the above structure, the pressing and sealing of the sealing ring 5 can be realized simultaneously during the process of installing the second column segment 32 into the first recessed cavity 22, that is, the sealing connection between the isolation sleeve 3 and the pump body shell 2 is conveniently realized.

[0065] Optionally, referring to Figures 1 to 3 , the first column segment 31 is provided with a second recessed cavity 33 at one end away from the second column segment 32;

[0066] The turbine 4 includes a rotor portion 41 and a blade portion 42; the rotor portion 41 is rotatably connected in the second recessed cavity 33, the blade portion 42 has oppositely arranged first and second end portions, the first end portion is connected with the rotor portion 41, and the second end portion is arranged towards the liquid inlet end 111, and the outer peripheral side of the blade portion 42 is arranged towards the liquid outlet end 112.

[0067] Specifically, referring to Figure 2 the orientation shown in the figure, the second recessed cavity 33 is provided at the upper end surface of the first column segment 31; the lower end portion of the blade portion 42 constitutes the first end portion, and the upper end portion of the blade portion 42 constitutes the second end portion.

[0068] The rotor portion 41 of the turbine 4 can be connected with a driving assembly to transmit mechanical energy (e.g. the rotating power of a motor) provided from outside to the blade portion 42, so as to drive the blade portion 42 to rotate. When the working liquid in the liquid immersion area 141 enters the blade portion 42 from the second end portion, the working liquid will be thrown to the outer circumferential side under the rotation of the blade portion 42, and in the process, the working liquid can obtain kinetic energy through the centrifugal action of the blade portion 42, and can be thrown out to the liquid outlet end 112 from the outer circumferential side of the blade portion 42 in the radial direction under a certain kinetic energy, so as to realize the transfer of the working liquid between the liquid inlet end 111 and the liquid outlet end 112.

[0069] In this embodiment, the rotor portion 41 with a small diameter is accommodated in the isolation sleeve 3, which can avoid unnecessary contact between the rotor portion 41 not directly participating in the working liquid transfer operation and the working liquid by excessively exposing the rotor portion 41 to the liquid immersion area 141, and can avoid the turbine 4 excessively protruding from the surface of the isolation sleeve 3, so as to further compress the space occupied by the pump liquid tank assembly.

[0070] Optionally, referring to Figures 1 to 3 , the first column segment 31 is provided with a third recessed cavity 34 at one end thereof away from the second column segment 32, and the second recessed cavity 33 is located within the coverage range of the third recessed cavity 34; the connecting portion of the rotor portion 41 and the blade portion 42 is provided with a limiting flange 43, and the limiting flange 43 is configured to abut against the third recessed cavity 34 in the radial direction.

[0071] Specifically, taking the orientation shown in Figure 2 as an example, the third recessed cavity 34 is provided at the upper end face of the first column segment 31, and the third recessed cavity 34 and the second recessed cavity 33 form a stepped hole structure; and the limiting flange 43 can be arranged around the connecting portion of the rotor portion 41 and the blade portion 42 around the center axis of rotation.

[0072] When the turbine 4 is radially offset from the isolation sleeve 3 to a certain extent, the vertical cavity wall of the third recessed cavity 34 can abut against the outer circumferential side of the limiting flange 43, so as to provide additional radial force to the turbine 4, thereby achieving radial limiting of the turbine 4, and avoiding the turbine 4 from being separated from the isolation sleeve 3 in the case of excessive rotation speed.

[0073] Optionally, referring to Figure 1 and Figure 2 , the inner cavity of the liquid storage tank 1 is provided with a partition structure 15, the partition structure 15 divides the inner cavity of the liquid storage tank 1 into a liquid storage cavity 1411 and a liquid outlet cavity 1412, the liquid storage cavity 1411 is in communication with the liquid inlet end 111, and the liquid outlet cavity 1412 is in communication with the liquid outlet end 112 and the pump body connecting port 113.

[0074] The partition structure 15 is provided with a liquid supply channel 151, the liquid supply channel 151 communicates the liquid storage cavity 1411 and the liquid outlet cavity 1412, and the liquid supply channel 151 is arranged towards the second end portion.

[0075] In the embodiment, the liquid storage cavity 1411 is located above the liquid outlet cavity 1412; the liquid storage cavity 1411 can temporarily store the working liquid supplied by the liquid inlet end 111 in a space independent of the liquid immersion area 141, and when subsequent cooling, washing, lubrication, hydraulic pressure, conveying or other operations using the working liquid are needed, a certain amount of working liquid in the liquid storage cavity 1411 can flow to the liquid outlet cavity 1412 through the liquid supply channel 151, and then the part of working liquid can be transported to the liquid outlet end 112 under the centrifugal action of the blade part 42.

[0076] Optionally, referring to Figure 1 and Figure 2 , the blade part 42 is provided with a flow guide groove (not shown in the figure), one end of the flow guide groove is arranged towards the liquid supply channel 151, and the other end of the flow guide groove is arranged towards the liquid outlet end 112; by means of the guiding function of the flow guide groove, the working liquid entering the blade part 42 can be guided to the liquid outlet end 112 along the flow guide groove under the centrifugal action, so that the flow direction of the working liquid is more accurate and controllable.

[0077] Optionally, referring to Figures 1 to 3 , the isolation sleeve 3 includes a mounting shaft 35, a first end of the mounting shaft 35 is connected to the cavity wall of the second recessed cavity 33, and a second end of the mounting shaft 35 is connected to the partition structure 15.

[0078] The turbine 4 is provided with a mounting through hole 44, the mounting through hole 44 penetrates the rotor part 41 and the blade part 42; the mounting shaft 35 is fitted in the mounting through hole 44.

[0079] Specifically, the lower end of the mounting shaft 35 can be integrally formed at the center of the bottom wall of the second recessed cavity 33, and the upper end of the mounting shaft 35 can be connected to the corresponding position on the partition structure 15 by means of locking, buckling connection, pressing, pin connection or the like.

[0080] In the actual assembly process, the mounting shaft 35 can be inserted into the mounting through hole 44 of the turbine 4 from bottom to top, so that the rotor part 41 is accommodated in the second recessed cavity 33; a bearing can be arranged between the mounting shaft 35 and the mounting through hole 44 to ensure that the turbine 4 can rotate smoothly relative to the mounting shaft 35; then the upper end of the mounting shaft 35 is connected and fixed to the partition structure 15 from bottom to top; in this way, the convenient assembly of the turbine 4 of the outer rotor structure on the isolation sleeve 3 is realized, and the partition structure 15 can form an axial limiting action on the turbine 4.

[0081] Optionally, referring to Figure 1 and Figure 2 , the liquid supply channel 151 is arranged around the mounting shaft 35, and a connecting arm body 152 is protrudingly arranged on the inner side wall of the liquid supply channel 151, and the connecting arm body 152 is connected to the second end of the mounting shaft 35.

[0082] In the embodiment, since the liquid supply channel 151 is arranged around the mounting shaft 35, when the working liquid in the liquid storage cavity 1411 flows to the liquid outlet cavity 1412 through the liquid supply channel 151, the working liquid can enter the vane part 42 from each position in the circumferential direction uniformly, and can be thrown out along the radial direction outward under the centrifugal force of the vane part 42, so that the working liquid cannot be excessively concentrated in a certain area of the vane part 42 and the centrifugal force of the vane part 42 in the rotating process cannot be fully exerted. By arranging the connecting arm body 152, the connection and fixation of the upper end of the mounting shaft 35 in the liquid supply channel 151 can be realized without interfering with the normal flow of the working liquid in the liquid supply channel 151.

[0083] Optionally, referring to Figure 1 and Figure 2 , the pump liquid tank assembly further comprises a wear-resistant gasket (not shown in the figure), the wear-resistant gasket is sleeved on the mounting shaft 35, one side end surface of the wear-resistant gasket abuts against the second end portion, and the other side end surface of the wear-resistant gasket abuts against the partition structure 15.

[0084] By arranging the wear-resistant gasket between the vane part 42 and the partition structure 15, the axial limiting effect of the turbine 4 can be formed, and direct contact between the vane part 42 and the partition structure 15 can be avoided, so that the abrasion between the vane part 42 and the partition structure 15 due to mutual friction can be reduced during the rotation of the turbine 4.

[0085] Optionally, referring to Figure 1 and Figure 2 , the pump liquid tank assembly further comprises a liquid level sensing device 6, a detection end 61 of the liquid level sensing device 6 is arranged in the liquid storage cavity 1411, and the liquid level sensing device 6 is used to output a liquid shortage signal when the detection end 61 is not in contact with the working liquid.

[0086] Specifically, the main body part of the liquid level sensing device 6 can be mounted on the outer side wall of the liquid storage tank 1, and the lowest point of the detection end 61 of the liquid level sensing device 6 can extend inward to the lowest liquid level line as shown in Figure 2 . Based on the difference in physical properties between air and liquid, when the detection end 61 is in contact with the working liquid, the liquid level sensing device 6 can obtain a corresponding feedback signal, so that it can be determined that the liquid surface in the current liquid storage cavity 1411 is above the lowest liquid level line, that is, the liquid amount in the liquid storage cavity 1411 at this time is sufficient, and the working liquid demand amount for subsequent cooling, washing, lubricating, hydraulic pressure, conveying and the like can be met. When the liquid level sensing device 6 does not obtain the above feedback signal, it indicates that the detection end 61 is not in contact with the working liquid, so that it can be determined that the liquid surface in the current liquid storage cavity 1411 is below the lowest liquid level line, and the working liquid in the liquid storage cavity 1411 can not meet the demand amount for subsequent operation; at this time, the liquid level sensing device 6 can output a liquid shortage signal to inform the relevant personnel to perform liquid supplementing operation, and the working liquid is supplemented into the liquid storage cavity 1411 from the liquid inlet end 111.

[0087] The liquid level sensing device 6 can be electrically connected with the display device and the prompting device through the master control module. The liquid shortage signal sent by the liquid level sensing device 6 can trigger the display device and the prompting device to perform alarm operation in the form of sound and light, text, image, etc., so as to directly remind the passenger, the driver, etc., to intervene in time, and avoid affecting subsequent cooling, washing, lubrication, hydraulic pressure, conveying, etc. due to insufficient working liquid and untimely liquid supplement. If the pre-flight inspection fails (i.e., the liquid level sensing device 6 outputs the liquid shortage signal), maintenance, etc. need to be performed. If a problem occurs during the navigation (i.e., the liquid level sensing device 6 outputs the liquid shortage signal), the whole machine needs to be forced to land.

[0088] However, in actual application, the traffic tool may be jolted, shaken, etc. during use, which may cause the working liquid in the liquid storage cavity 1411 to surge. Based on this, even if the liquid level in the liquid storage cavity 1411 is lower than the lowest liquid level line in the static state, when the working liquid surges, the surging working liquid may still splash upwards to the detection end 61, causing the detection end 61 to be immersed in the working liquid, and thus causing the liquid level sensing device 6 to misjudge that the liquid amount in the current liquid storage cavity 1411 is sufficient.

[0089] Based on the above problems, the following embodiments are proposed:

[0090] Referring to Figure 1 , Figure 2 and Figure 4 , the pump liquid tank assembly further comprises a liquid separation plate 7, the liquid separation plate 7 is arranged in the liquid storage cavity 1411, and the liquid separation plate 7 is used to separate the liquid storage cavity 1411 into a detection area 14111 and a liquid storage area 14112. The detection area 14111 is located above the liquid storage area 14112, and the detection end 61 is arranged in the detection area 14111. The liquid separation plate 7 is provided with a plurality of flow-through holes 71, and the flow-through holes 71 communicate the detection area 14111 and the liquid storage area 14112.

[0091] The liquid separation plate 7 of the embodiment can be arranged at the lowest liquid level line. When the liquid amount in the liquid storage cavity 1411 is insufficient (i.e., the liquid level in the liquid storage cavity 1411 is lower than the liquid separation plate 7), the upwardly splashing working liquid has a small coverage range, and thus most of the splashing working liquid can be blocked by the liquid separation plate 7, so that the splashing working liquid can be prevented from contacting the detection end 61 to a certain extent, and thus the probability of misjudgment of the liquid level sensing device 6 can be reduced. When the liquid amount in the liquid storage cavity 1411 is sufficient, the working liquid in the liquid storage area 14112 can flow to the detection area 14111 through the flow-through holes 71 with small diameters on the liquid separation plate 7, so that the lowest point of the detection end 61 is immersed in the working liquid. At this time, the liquid level sensing device 6 can normally determine the current liquid level condition.

[0092] Based on the above settings, the probability of false judgment of the liquid level sensing device 6 can be reduced, and the accuracy of liquid level detection can be improved.

[0093] Optionally, referring to Figure 1 and Figure 2 , the pump body shell 2 is locked to the liquid storage tank 1 through a plurality of threaded connections 8, and the plurality of threaded connections 8 are arranged around the pump body connecting port 113.

[0094] Specifically, taking a bolt as an example of the threaded connection 8, an outer circumferential side of an upper portion of the pump body shell 2 can be provided with an outwardly extending first flange portion 23, and a plurality of connecting through holes are arranged on the first flange portion 23 in a circumferential direction. An outer circumferential side of a lower portion of the liquid storage tank 1 can be provided with an outwardly extending second flange portion 16, and a plurality of connecting screw holes corresponding to the connecting through holes are arranged on the second flange portion 16 in a circumferential direction; when the first flange portion 23 abuts against the second flange portion 16, the threaded connection 8 can pass through each connecting through hole from bottom to top and be locked in the corresponding connecting screw hole, so as to lock the pump body shell 2 to the liquid storage tank 1. Based on the threaded connection mode of the present embodiment, the connection between the pump body shell 2 and the liquid storage tank 1 can be conveniently achieved, and the connection stability at each position in the circumferential direction can be ensured, and the pump body shell 2 can also be conveniently disassembled during subsequent maintenance and replacement.

[0095] Optionally, referring to Figure 1 and Figure 2 , a sealing structure (not shown in the figure) is arranged at the connection between the pump body shell 2 and the liquid storage tank 1; by arranging the sealing structure, the working liquid in the liquid immersion area 141 can be prevented from leaking to the outside through the gap between the pump body shell 2 and the liquid storage tank 1.

[0096] Please refer to Figure 1 and Figure 2 , the present application also provides a vehicle, which comprises a fluid application module and the pump liquid tank assembly of any one of the above embodiments, and the fluid application module is in communication with the liquid outlet 112 of the pump liquid tank assembly.

[0097] In the present embodiment, the vehicle includes but is not limited to a common ground vehicle, a flying vehicle, etc.; the fluid application module can refer to any functional module that performs cooling, washing, lubrication, hydraulic pressure, conveying, etc. using the working liquid supplied by the pump liquid tank assembly.

This design cancels the external pipeline and other connecting devices, significantly improves the compactness of the structure, reduces the space occupation, and effectively reduces the overall weight. Therefore, the pump liquid tank assembly can better meet the needs of flying cars and other vehicles with extremely strict requirements on weight and space. At the same time, the above integrated structure can reduce the complexity of the system, reduce the risk of liquid leakage, and thus better maintain the reliability and stability of the system under complex working conditions.
