Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-mounted power supply equipment, and in particular to a power supply equipment. Background Art

[0002] The on-board power supply equipment can supply power to engineering vehicles. However, a cooling device is provided in the on-board power supply equipment. The cooling device is used to dissipate heat from the power supply part in the on-board power supply equipment. The provision of the cooling device not only increases the volume of the on-board power supply equipment, but also makes the cooling device prone to damage, thereby increasing the maintenance cost of the on-board power supply equipment. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, the present invention provides a power supply device.

[0005] In view of this, the first aspect of the present invention provides a power supply device, including: a power distribution component; a cooling pipeline, including a pipe mouth, arranged opposite to the power distribution component, for cooling the power distribution component; a switch device, connected to the cooling pipeline, for opening or closing the pipe mouth.

[0006] The power supply equipment provided by the present invention includes a distribution component, a cooling pipeline and a switch device. The distribution component can store electricity. For example, the distribution component can be a battery. After storing electricity, the distribution component can supply power to the power structure, tooling structure or other equipment that requires power supply of the engineering vehicle, so that the distribution component can be used as an independent power source.

[0007] The power supply equipment also includes a cooling pipeline, which is used to cool the distribution component. When the engineering vehicle is working, the distribution component starts to work. A large amount of heat will be generated when the distribution component is working. In order to avoid damage to the distribution component, the distribution component is cooled by the cooling pipeline, so as to ensure the stability of the distribution component when working. The cooling pipeline can be arranged in contact with the distribution component, and coolant is passed into the cooling pipeline so that the cooling pipeline can perform heat exchange with the distribution component.

[0008] The cooling pipeline is provided with a nozzle, which can be connected to an external pipeline. For example, a pump body and an external pipeline can be provided on an engineering vehicle. The pump body can drive the coolant in the external pipeline to flow. When the external pipeline and the cooling pipeline are connected, the pump body drives the coolant to circulate in the cooling pipeline and the external pipeline to achieve the heat dissipation function of the distribution component. The distribution component of the present invention is not provided with an independent cooling device, which can reduce the volume and weight of the distribution component, facilitate the transportation and installation of the distribution component, and the volume of the distribution component is small, reducing the space occupied by the distribution component. Moreover, since the distribution component is not provided with an independent cooling device, the maintenance cost caused by damage to the cooling device can be reduced. The heat dissipation of the distribution component is carried out by circulating the coolant. The external heat dissipation device can only include a pump body and an external pipeline. The external heat dissipation device has a simple structure and is not easy to be damaged.

[0009] The switch device can open or close the pipe mouth. When the cooling pipeline and the external pipeline are connected, the switch device opens the pipe mouth so that the coolant can flow into the cooling pipeline. When the external pipeline is removed from the pipe mouth, the switch device closes the pipe mouth to prevent the coolant in the cooling pipeline from flowing out.

[0010] In addition, the above-mentioned carrier lifting device provided by the present invention may also have the following additional technical features:

[0011] In one possible design, the power supply device also includes: a power supply manager, connected to the power distribution component, for controlling the operation of the power distribution component and monitoring the operating temperature of the power distribution component.

[0012] In this design, a power supply manager is also provided in the power supply device, and the power supply manager is connected to the power distribution component. A control circuit is provided in the power supply manager, and the control circuit is used to control the operation of the power distribution component. When the assembly of the power distribution component is completed, the power supply manager controls the power distribution component to deliver electric energy that meets the power supply demand to the power-consuming equipment, such as ensuring that the power supply voltage output by the power distribution component matches the working voltage of the power-consuming equipment. At the same time, a temperature sensor is also provided on the power supply manager, and the temperature sensor can be used to obtain the working temperature of the power distribution component. When the power supply manager determines that the obtained working temperature exceeds the preset temperature, the power supply manager can issue an early warning to the user or control the power distribution component to suspend operation to avoid high-temperature damage to the power distribution component, thereby achieving the technical effect of optimizing the structure of the power distribution component, improving the intelligence level of the power distribution component, and improving the working safety and reliability of the power supply equipment.

[0013] In a possible design, the power supply equipment also includes: a pipe joint, connected to the cooling pipe, and a switch device is arranged on the pipe joint or the cooling pipe; a pipe socket, detachably connected to the pipe joint; wherein the switch device opens the pipe mouth when the pipe joint and the pipe socket are connected, and closes the pipe mouth when the pipe joint and the pipe socket are disconnected.

[0014] In this design, the power supply equipment also includes a pipe joint and a pipe socket. The pipe joint is arranged on the cooling pipe, and the pipe socket is connected to the external pipe. When the external pipe drives the pipe socket to connect with the pipe joint, the switch device opens the pipe mouth, so that the coolant can flow into the cooling pipe. The temperature of the coolant is relatively low, and the cooling pipe can exchange heat with the power distribution component, thereby realizing the heat dissipation process of the power distribution component. When the external pipe is disassembled, the pipe socket and the pipe joint are disconnected, and the switch device closes the pipe mouth at this time to prevent the coolant in the cooling pipe from flowing out.

[0015] By arranging the pipe socket and the pipe joint in coordination, the stability of the switch device in opening or closing the pipe port can be ensured, the failure rate of the distribution component can be reduced, the heat dissipation of the distribution component can be stably achieved, and the energy waste caused by the outflow of coolant can be avoided.

[0016] In a possible design, the power supply equipment further includes: a box body, in which the power distribution assembly and the cooling pipeline are arranged, and the pipeline joint is connected to the box body.

[0017] In this design, the power distribution components and cooling pipelines are arranged in a box, which can protect the power distribution components and cooling pipelines, prevent other components from colliding with the power distribution components and cooling pipelines, and prevent the power distribution components and cooling pipelines from being damaged due to collisions.

[0018] The power distribution assembly and the cooling pipeline are both arranged in the box, which can improve the convenience of carrying the power distribution assembly. Moreover, as long as the box is fixed in the installation position, the power distribution assembly and the cooling pipeline are not easy to shake, that is, there is no need to install and fix the power distribution assembly and the cooling pipeline separately, which reduces the installation steps of the power distribution assembly and improves the convenience of assembling the power distribution assembly.

[0019] The pipe joint is arranged on the box body, that is, the pipe joint is not easy to move in the box body, so it is convenient to match the pipe socket with the pipe joint, and the convenience of connecting the external pipe with the cooling pipe is improved. In addition, the pipe joint is not easy to shake in the box body, so that the pipe joint is not easy to be bumped, thereby reducing the damage rate of the pipe joint.

[0020] In a possible design, the power supply equipment also includes: a first heat exchange pipeline, which is connected to the cooling pipeline to form a circulation flow path; and a first pump body, which is arranged on the first heat exchange pipeline.

[0021] Cooling liquid can flow in the first heat exchange pipeline, and the first pump body can drive the coolant in the first heat exchange pipeline to flow. When the first heat exchange pipeline and the cooling pipeline are connected, the first pump body drives the coolant to circulate in the cooling pipeline and the first heat exchange pipeline, thereby realizing the heat dissipation function of the power distribution component. In the present invention, the cooling device is separated from the power distribution component, which can reduce the volume and weight of the power distribution component, facilitate the transportation and installation of the power distribution component, and the power distribution component has a small volume, which reduces the space occupied by the power distribution component. Moreover, since an independent cooling device is not provided in the power distribution component, the maintenance cost caused by damage to the cooling device can be reduced. The power distribution component is cooled by circulating the coolant, and the external heat dissipation device can only include the first pump body and the first heat exchange pipeline. The external heat dissipation device has a simple structure and is not easy to be damaged.

[0022] In a possible design, the power supply device also includes: an air conditioner, which is arranged opposite to the first heat exchange pipeline and is used to cool the heat exchange pipeline.

[0023] In this design, after the cooling pipeline exchanges heat with the distribution component, the temperature of the coolant in the cooling pipeline increases. A heat dissipation device is required to cool the coolant so that the temperature of the coolant flowing through the distribution component is lower, thereby improving the heat exchange efficiency between the cooling pipeline and the distribution component.

[0024] Specifically, an air conditioner on the working power supply device is arranged opposite to the first heat exchange pipeline, and the air conditioner can cool the coolant in the first heat exchange pipeline, so that the temperature of the coolant flowing through the power distribution component again is lower.

[0025] The air conditioner in the power supply equipment can adjust the temperature of the cab where the staff sits. The coolant in the first heat exchange pipeline is cooled by the air conditioner in the project, and there is no need to set up an additional separate heat dissipation device. This not only reduces the number of components on the power supply equipment, but also effectively reduces the production cost of the power supply equipment.

[0026] In a possible design, the power supply device also includes: an air conditioning manager, connecting the air conditioner and the power supply manager.

[0027] In this design, an air conditioning manager is also provided on the power supply device, and the air conditioning manager is connected to the air conditioner to control the operation of the air conditioner.

[0028] In one possible design, based on the power supply manager determining that the operating temperature is greater than a preset temperature, the air conditioning manager controls the air conditioner to cool the first heat exchange pipeline.

[0029] In this design, the air conditioning manager can cool or heat the cab of the engineering vehicle according to the needs of the user, and can also control the air conditioner to cool the first heat exchange pipeline. On this basis, after the connection between the power distribution component and the power supply device is completed, the air conditioning manager is connected to the power supply manager. During the working process, when the power supply manager determines that the current operating temperature of the power distribution component is greater than the preset temperature, the power supply manager sends a control instruction to the air conditioning manager, and the air conditioning manager controls the air conditioner to cool the first heat exchange management according to the control instruction to reduce the temperature of the cooling medium in the first heat exchange pipeline and the cooling pipeline, thereby realizing the cooling of the power distribution component and avoiding the further increase of the temperature of the power distribution component. Among them, the preset temperature corresponds to the highest safe operating temperature of the power distribution component. When the operating temperature of the power distribution component is higher than the preset temperature, the safety hazard of the power distribution component increases significantly. By setting the air conditioning manager, the power supply manager and the air conditioning manager can be linked to achieve automatic cooling of the power distribution component, thereby greatly improving the safety and reliability of the power distribution component and realizing intelligent power supply.

[0030] In a possible design, the power supply device also includes: a body assembly; a power supply line connecting the body assembly and a power distribution assembly, and the power distribution assembly is used to supply power to the body assembly.

[0031] In this design, the power supply device also includes an upper assembly and a power supply line, and the power supply line can connect the upper assembly and the power distribution assembly, so that the power distribution assembly can supply power to the upper assembly. For example, when the power supply device is connected to a concrete mixer truck, the upper assembly can be a power assembly that drives the mixing roller to rotate, and the power distribution assembly can supply power to the power assembly. Or when the power supply device is connected to an engineering pump truck, the upper assembly can be a drive assembly that drives the folding arm on the engineering pump truck, and the power distribution assembly can supply power to the drive assembly.

[0032] The power supply equipment also includes a second heat exchange pipeline, which is connected with the cooling pipeline to form a circulation flow path; and a second pump body, which is arranged on the second heat exchange pipeline.

[0033] The distribution component can store electric energy. When the electric energy of the distribution component is about to run out, the power supply equipment is needed to supply power to the distribution component. When the power supply equipment is charging the distribution component, the distribution component will also generate heat. Therefore, the second heat exchange pipeline on the power supply equipment can be connected to the cooling pipeline. The second pump body drives the coolant in the second heat exchange pipeline to flow, thereby realizing the heat dissipation function of the distribution component. Similarly, separating the cooling device from the distribution component can reduce the volume and weight of the distribution component, making it easier to carry and install the distribution component. The distribution component is small in size, which reduces the space occupied by the distribution component on the vehicle. Moreover, since no independent cooling device is provided in the distribution component, the maintenance cost caused by damage to the cooling device can be reduced. The heat dissipation of the distribution component is carried out by circulating the coolant. The external heat dissipation device can only include the second pump body and the second heat exchange pipeline. The external heat dissipation device has a simple structure and is not easy to be damaged.

[0034] In one possible design, the power supply device further includes: a water cooling device connected to the second heat exchange pipeline and the power supply manager;

[0035] In this design, a water cooling device is also provided on the power supply equipment, and the water cooling device is connected to the second heat exchange pipeline. The water cooling device can dissipate heat from the high-temperature cooling medium flowing into it to output the low-temperature cooling medium to the second heat exchange pipeline, thereby ensuring the cooling capacity of the second heat exchange pipeline and the cooling pipeline connected thereto.

[0036] In one possible design, based on the power supply manager determining that the operating temperature is greater than a preset temperature, the power supply manager controls the water cooling device to operate.

[0037] In this design, after the connection between the power supply component and the power supply equipment is completed, the water cooling device is connected to the power supply manager. During operation, when the power supply manager determines that the current operating temperature of the distribution component is greater than the preset temperature, the power supply manager sends a control instruction to the water cooling device, and the water cooling device cools the second heat exchange pipeline according to the control instruction to reduce the temperature of the cooling medium in the second heat exchange pipeline and the cooling pipeline, thereby achieving cooling for the distribution component and preventing the temperature of the distribution component from further increasing. Among them, the preset temperature corresponds to the maximum safe operating temperature of the distribution component. When the operating temperature of the distribution component is higher than the preset temperature, the safety hazard of the distribution component increases significantly. This design realizes the automatic cooling of the distribution component, thereby greatly improving the safety and reliability of the distribution component and realizing intelligent power supply.

[0038] In a possible design, the power supply equipment also includes: a charging device; a charging circuit, connecting the charging device and the power distribution component, and the charging device is used to charge the power distribution component.

[0039] In this design, when the power distribution component needs to be powered, a charging line is used to connect the charging device and the power distribution component, so that the charging device can power the power distribution component. After charging, the power distribution component can power the electrical equipment. The power distribution component serves as an independent power supply. After the electrical equipment is moved to the workplace, there is no need to find a fixed power source such as a socket, but the electrical equipment can be conveniently powered by the power distribution component.

[0049] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0050] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0051] Refer to the following Figures 1 to 5 A power supply device 100 according to some embodiments of the present invention is described.

[0052] Combination Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of the first aspect of the present invention provides a power supply device 100, comprising: a power distribution component 150; a cooling pipeline 110, comprising a pipe mouth, arranged opposite to the power distribution component 150, for cooling the power distribution component 150; a switch device, connected to the cooling pipeline 110, for opening or closing the pipe mouth.

[0053] The power supply device 100 provided in this embodiment includes a power distribution component 150, a cooling pipeline 110 and a switching device. The power distribution component 150 can store electricity. For example, the power distribution component 150 can be a battery. After storing electricity, the power distribution component 150 can supply power to a vehicle or other equipment that requires power supply, so that the power distribution component 150 serves as an independent power source.

[0054] The power supply device 100 also includes a cooling pipeline 110, which is used to cool the distribution component 150. When the power supply device 100 is working, the distribution component 150 starts to work. A large amount of heat will be generated when the distribution component 150 is working. In order to avoid damage to the distribution component 150, the distribution component 150 is cooled by the cooling pipeline 110, so as to ensure the stability of the distribution component 150 when working. The cooling pipeline 110 can be arranged to contact the distribution component 150, and coolant is passed into the cooling pipeline 110, so that the cooling pipeline 110 can perform heat exchange with the distribution component 150.

[0055] The cooling pipeline 110 is provided with a nozzle, which can be connected to an external pipeline. For example, a pump body and an external pipeline can be provided on the power supply device 100. The pump body can drive the coolant in the external pipeline to flow. When the external pipeline and the cooling pipeline 110 are connected, the pump body drives the coolant to circulate in the cooling pipeline 110 and the external pipeline to achieve the heat dissipation function of the distribution component 150. In the present invention, no independent cooling device is provided in the distribution component 150, which can reduce the volume and weight of the distribution component 150, facilitate the transportation and installation of the distribution component 150, and reduce the space occupied by the distribution component 150. Moreover, since no independent cooling device is provided in the distribution component 150, the maintenance cost caused by damage to the cooling device can be reduced. The heat dissipation of the distribution component 150 is carried out by circulating the coolant. The external heat dissipation device can only include a pump body and an external pipeline. The external heat dissipation device has a simple structure and is not easy to be damaged.

[0056] The switch device can open or close the pipe mouth. When the cooling pipeline 110 and the external pipeline are connected, the switch device opens the pipe mouth so that the coolant can flow into the cooling pipeline 110. When the external pipeline is removed from the pipe mouth, the switch device closes the pipe mouth to prevent the coolant in the cooling pipeline 110 from flowing out.

[0057] Combination Figure 1 , Figure 2 and Figure 3 As shown, in a possible embodiment, the power supply device 100 further includes: a power supply manager 120 connected to the power distribution component 150 , and used to control the operation of the power distribution component 150 and monitor the operating temperature of the power distribution component 150 .

[0058] In this embodiment, the power supply device 100 is also provided with a power supply manager 120, which is connected to the power distribution component 150. The power supply manager 120 is provided with a control circuit, which is used to control the operation of the power distribution component 150. When the assembly of the power distribution component 150 is completed, the power supply manager 120 controls the power distribution component 150 to deliver electric energy that meets the power supply demand to the power-consuming device, for example, to ensure that the power supply voltage output by the power distribution component 150 is consistent with the working voltage of the power-consuming device. At the same time, the power supply manager 120 is also provided with a temperature sensor, which can be used to obtain the working temperature of the power distribution component 150. When the power supply manager 120 determines that the obtained working temperature exceeds the preset temperature, the power supply manager 120 can issue an early warning to the user or control the power distribution component 150 to suspend operation to avoid the power distribution component 150 from being damaged by high temperature, thereby achieving the technical effect of optimizing the structure of the power distribution component 150, improving the intelligence of the power distribution component 150, and improving the working safety and reliability of the power supply device 100.

[0059] Combination Figure 2 , Figure 3 and Figure 5 As shown, in a possible embodiment, the power supply device 100 also includes: a pipe connector 130, which is connected to the cooling pipe 110, and a switch device is arranged on the pipe connector 130 or the cooling pipe 110; a pipe socket 140, which is detachably connected to the pipe connector 130; wherein the switch device opens the pipe mouth when the pipe connector 130 and the pipe socket 140 are connected, and closes the pipe mouth when the pipe connector 130 and the pipe socket 140 are disconnected.

[0060] In this embodiment, the power supply device 100 further includes a pipe joint 130 and a pipe socket 140. The pipe joint 130 is arranged on the cooling pipe 110. When an external pipe needs to be connected, the pipe socket 140 is connected to the external pipe. When the external pipe drives the pipe socket 140 to connect with the pipe joint 130, the switch device opens the pipe opening so that the coolant can flow into the cooling pipe 110. The temperature of the coolant is relatively low, and the cooling pipe 110 can exchange heat with the power distribution component 150, thereby realizing the heat dissipation process of the power distribution component 150. When the external pipe is disassembled, the pipe socket 140 and the pipe joint 130 are disconnected, and the switch device closes the pipe opening at this time to prevent the coolant in the cooling pipe 110 from flowing out.

[0061] By arranging the pipe socket 140 and the pipe joint 130 in coordination, the stability of the switch device in opening or closing the pipe port can be ensured, the failure rate of the distribution component 150 can be reduced, the heat dissipation of the distribution component 150 can be stably achieved, and energy waste caused by the outflow of coolant can be avoided.

[0062] Combination Figure 2 , Figure 3 and Figure 5 As shown, in a possible embodiment, the pipe connector 130 includes a flow channel connected to the pipe mouth, a limit portion is provided in the flow channel, and the switching device includes: a valve core, which is movably arranged in the flow channel; wherein the valve core opens the flow channel when it is spaced from the limit portion, and closes the flow channel when the valve core contacts the limit portion.

[0063] In this embodiment, the structure of the pipe connector 130 is specifically defined. The pipe connector 130 includes a flow channel, which is connected to the pipe mouth. The limiting part in the flow channel can cooperate with the valve core, and the valve core can move in the flow, so that the valve core can be separated from or contacted with the limiting part.

[0064] Specifically, when the power distribution assembly 150 needs to be cooled, the pipe joint 130 cooperates with the limiting part, and the pipe joint 130 pushes the valve core to move in the flow channel, so that the valve core is separated from the limiting part. At this time, the flow channel is open, and the coolant in the external pipe can flow into the flow channel and into the cooling pipe 110 through the pipe mouth. The cooling pipe 110 can exchange heat with the power distribution assembly 150, thereby realizing the heat dissipation process of the power distribution assembly 150. When the external pipe is disassembled, the pipe socket 140 no longer drives the valve core, and the valve core contacts the limiting part. At this time, the flow channel is closed, and the coolant in the cooling pipe 110 will not flow out, avoiding the waste of coolant.

[0065] In a possible embodiment, the power supply device 100 also includes: an elastic member connecting the valve core and the pipe connector 130; a trigger part, which is arranged on the pipe socket 140. When the pipe socket 140 and the pipe connector 130 are connected, the trigger part contacts the valve core and compresses the elastic member, and the valve core is spaced apart from the limiting part.

[0066] In this embodiment, it is specifically defined that a trigger part is set on the pipeline. When the power distribution component 150 needs to be used to power the electrical equipment, the pipeline socket 140 is connected to the pipeline joint 130. The trigger part on the pipeline socket 140 can push the valve core. Since an elastic member is set between the valve core and the pipeline joint 130, when the trigger part pushes the valve core, the valve core moves in the flow channel and drives the elastic member to undergo elastic deformation. At this time, the valve core and the limiting part are spaced apart, the flow channel is opened, and the coolant in the external pipeline can flow into the flow channel and into the cooling pipeline 110 through the pipe mouth. The cooling pipeline 110 can exchange heat with the power distribution component 150, thereby realizing the heat dissipation process of the power distribution component 150. When the external pipe is disassembled, the pipe socket 140 drives the trigger part to separate from the pipe joint 130, and the trigger part no longer drives the valve core. The deformed elastic part can drive the valve core to move and reset, that is, the elastic part drives the valve core to automatically contact the limit part. At this time, the flow channel is closed, and the coolant in the cooling pipe 110 will not flow out, avoiding waste of coolant.

[0067] By providing an elastic member to drive the valve core to move and reset, the two steps of disassembly of the pipeline socket 140 and closing the flow channel can be carried out simultaneously without the user actively closing the flow. This not only reduces the workload of the staff, but also effectively ensures that the coolant will not be wasted.

[0068] In a possible embodiment, the power supply device 100 further includes: a box, in which the power distribution assembly 150 and the cooling pipeline 110 are arranged, and the pipeline connector 130 is connected to the box.

[0069] In this embodiment, the power distribution assembly 150 and the cooling pipeline 110 are arranged in a box, which can protect the power distribution assembly 150 and the cooling pipeline 110, prevent other components from colliding with the power distribution assembly 150 and the cooling pipeline 110, and prevent the power distribution assembly 150 and the cooling pipeline 110 from being damaged due to collision.

[0070] The power distribution assembly 150 and the cooling pipeline 110 are both arranged in the box, which can improve the convenience of carrying the power distribution assembly 150. Moreover, as long as the box is fixed at the installation position, the power distribution assembly 150 and the cooling pipeline 110 are not easy to shake, that is, there is no need to install and fix the power distribution assembly 150 and the cooling pipeline 110 separately, which reduces the installation steps of the power distribution assembly 150 and improves the assembly convenience of the power distribution assembly 150.

[0071] The pipe joint 130 is arranged on the box, that is, the pipe joint 130 is not easy to move in the box, so it is convenient to match the pipe socket 140 with the pipe joint 130, and improve the convenience of connecting the external pipe with the cooling pipe 110. In addition, the pipe joint 130 is not easy to shake in the box, so that the pipe joint 130 is not easy to be bumped, thereby reducing the damage rate of the pipe joint 130.

[0072] Combination Figure 2 , Figure 3 and Figure 5 As shown, in a possible embodiment, the power supply device 100 further includes: a first heat exchange pipeline 210 connected to the cooling pipeline 110 to form a circulation flow path; and a first pump body disposed on the first heat exchange pipeline 210 .

[0073] The first heat exchange pipeline 210 can flow coolant, and the first pump body can drive the coolant in the first heat exchange pipeline 210 to flow. When the first heat exchange pipeline 210 and the cooling pipeline 110 are connected, the first pump body drives the coolant to circulate in the cooling pipeline 110 and the first heat exchange pipeline 210, so as to achieve the heat dissipation function of the power distribution component 150. In the present invention, the cooling device is separated from the power distribution component 150, which can reduce the volume and weight of the power distribution component 150, facilitate the transportation and installation of the power distribution component 150, and the power distribution component 150 has a small volume, which reduces the space occupied by the power distribution component 150 on the power supply device 100. Moreover, since the power distribution component 150 is not provided with an independent cooling device, the maintenance cost caused by the damage of the cooling device can be reduced. The power distribution component 150 is cooled by circulating the coolant, and the external heat dissipation device can only include the first pump body and the first heat exchange pipeline 210. The external heat dissipation device has a simple structure and is not easy to be damaged.

[0074] Combination Figure 2 and Figure 3As shown, in a possible embodiment, the power supply device 100 further includes: an air conditioner 220, which is arranged opposite to the first heat exchange pipeline 210 and is used to cool the heat exchange pipeline.

[0075] In this embodiment, after the cooling pipe 110 exchanges heat with the distribution component 150, the temperature of the coolant in the cooling pipe 110 increases, and a heat dissipation device needs to be provided to cool the coolant so that the temperature of the coolant flowing through the distribution component 150 is lower, thereby improving the heat exchange efficiency between the cooling pipe 110 and the distribution component 150.

[0076] Specifically, the air conditioner 220 on the working power supply device 100 is arranged opposite to the first heat exchange pipeline 210. The air conditioner 220 can cool the coolant in the first heat exchange pipeline 210, so that the temperature of the coolant flowing through the distribution component 150 again is lower.

[0077] The air conditioner 220 in the power supply device 100 can adjust the temperature of the cab where the staff sits. The coolant in the first heat exchange pipeline 210 is cooled by the air conditioner 220 in the project, and there is no need to set up an additional separate heat dissipation device. This not only reduces the number of components on the power supply device 100, but also can effectively reduce the production cost of the power supply device 100.

[0078] Combination Figure 1 , Figure 2 and Figure 3 As shown, in a possible embodiment, the power supply device 100 also includes: an air conditioning manager 230, which connects the air conditioner 220 and the power supply manager 120; wherein, based on the power supply manager 120 determining that the operating temperature is greater than the preset temperature, the air conditioning manager 230 controls the air conditioner 220 to cool the first heat exchange pipeline 210.

[0079] In this embodiment, the power supply device 100 is also provided with an air conditioning manager 230, which is connected to the air conditioner 220 and is used to control the operation of the air conditioner 220. Specifically, the air conditioning manager 230 can cool or heat the cab of the power supply device 100 according to the needs of the user, and can also control the air conditioner 220 to cool the first heat exchange pipeline 210. On this basis, after the connection between the power distribution component 150 and the power supply device 100 is completed, the air conditioning manager 230 is connected to the power supply manager 120. During the operation, when the power supply manager 120 determines that the current operating temperature of the power distribution component 150 is greater than the preset temperature, the power supply manager 120 sends a control instruction to the air conditioning manager 230, and the air conditioning manager 230 controls the air conditioner 220 to cool the first heat exchange management according to the control instruction, so as to reduce the temperature of the cooling medium in the first heat exchange pipeline 210 and the cooling pipeline 110, thereby realizing the cooling of the power distribution component 150 and preventing the temperature of the power distribution component 150 from further increasing. The preset temperature corresponds to the highest safe operating temperature of the power distribution assembly 150. When the operating temperature of the power distribution assembly 150 is higher than the preset temperature, the potential safety hazard of the power distribution assembly 150 increases significantly. By setting the air conditioning manager 230, the power supply manager 120 and the air conditioning manager 230 can be controlled in linkage to realize automatic cooling of the power distribution assembly 150, thereby greatly improving the safety and reliability of the power distribution assembly 150 and realizing intelligent power supply.

[0080] Combination Figure 2 and Figure 3 As shown, in a possible embodiment, the power supply device 100 further includes: a body assembly; a power supply line connecting the body assembly and a power distribution assembly 150, and the power distribution assembly 150 is used to supply power to the body assembly.

[0081] In this embodiment, the power supply device 100 also includes an upper assembly and a power supply line, and the power supply line can connect the upper assembly and the power distribution assembly 150, so that the power distribution assembly 150 can supply power to the upper assembly. For example, when the power supply device 100 is connected to a concrete mixer truck, the upper assembly can be a power assembly that drives the mixing roller to rotate, and the power distribution assembly 150 can supply power to the power assembly. Or when the power supply device 100 is connected to an engineering pump truck, the upper assembly can be a drive assembly that drives the folding arm on the engineering pump truck, and the power distribution assembly 150 can supply power to the drive assembly.

[0082] The power supply device 100 further includes a second heat exchange pipeline 310 , which is in communication with the cooling pipeline 110 to form a circulation flow path; and a second pump body, which is disposed on the second heat exchange pipeline 310 .

[0083] The power distribution component 150 can store electric energy. When the power distribution component 150 is about to run out of electric energy, the power supply device 100 needs to be used to supply power to the power distribution component 150. When the power supply device 100 is charging the power distribution component 150, the power distribution component 150 will also generate heat. Therefore, the second heat exchange pipeline 310 on the power supply device 100 can be connected to the cooling pipeline 110, and the second pump body drives the coolant in the second heat exchange pipeline 310 to flow, so as to achieve the heat dissipation function of the power distribution component 150. Similarly, separating the cooling device from the power distribution component 150 can reduce the volume and weight of the power distribution component 150, and facilitate the handling and installation of the power distribution component 150. The power distribution component 150 is small in size, which reduces the space occupied by the power distribution component 150 on the power supply device 100. Moreover, since there is no independent cooling device in the power distribution component 150, the maintenance cost caused by the damage of the cooling device can be reduced. The power distribution assembly 150 is cooled by circulating the coolant, and the external heat dissipation device may only include a second pump body and a second heat exchange pipeline 310. The external heat dissipation device has a simple structure and is not easily damaged.

[0084] Combination Figure 4 As shown, in a possible embodiment, the power supply device 100 also includes: a water cooling device 320, connecting the second heat exchange pipeline 310 and the power supply manager 120; wherein, based on the power supply manager 120 determining that the operating temperature is greater than the preset temperature, the power supply manager 120 controls the water cooling device 320 to operate.

[0085] In this embodiment, the power supply device 100 is also provided with a water cooling device 320, which is connected to the second heat exchange pipeline 310. The water cooling device 320 can dissipate heat from the high-temperature cooling medium flowing into it, so as to output the low-temperature cooling medium to the second heat exchange pipeline 310, thereby ensuring the cooling capacity of the second heat exchange pipeline 310 and the cooling pipeline 110 connected thereto. On this basis, after the connection between the power supply component 150 and the power supply device 100 is completed, the water cooling device 320 is connected to the power supply manager 120. During operation, when the power supply manager 120 determines that the current operating temperature of the power distribution component 150 is greater than the preset temperature, the power supply manager 120 sends a control instruction to the water cooling device 320, and the water cooling device 320 cools the second heat exchange pipeline 310 according to the control instruction to reduce the temperature of the cooling medium in the second heat exchange pipeline 310 and the cooling pipeline 110, thereby realizing cooling for the power distribution component 150 and preventing the temperature of the power distribution component 150 from further increasing. The preset temperature corresponds to the maximum safe operating temperature of the power distribution assembly 150. When the operating temperature of the power distribution assembly 150 is higher than the preset temperature, the potential safety hazard of the power distribution assembly 150 increases significantly. This design realizes the automatic cooling of the power distribution assembly 150, thereby greatly improving the safety and reliability of the power distribution assembly 150 and realizing intelligent power supply.

[0086] In a possible embodiment, the power supply device 100 further includes: a charging device; and a charging circuit connecting the charging device and the power distribution component 150 , wherein the charging device is used to charge the power distribution component 150 .

[0087] In this embodiment, when the power distribution component 150 needs to be powered, a charging line is used to connect the charging device and the power distribution component 150, so that the charging device can power the power distribution component 150. After charging, the power distribution component 150 can power the power supply device 100. The power supply device 100 serves as an independent power supply. After the power supply device 100 is moved to the workplace, there is no need to find a fixed power source such as a socket, but the power supply device 100 can be conveniently powered by the power supply device 100. Specific embodiment:

[0089] The present invention is a battery cooling system solution for a battery-swap vehicle, which integrates a first heat exchange pipeline 210, a first pump body and the vehicle's air-conditioning system, so that a set of cooling devices for the entire vehicle can simultaneously meet the cooling needs of the cab refrigeration and energy supply devices. At the same time, a water-cooled quick-change connector is used. The water-cooled quick-change connector has the functions of insertion conduction and removal of self-locking sealing. After the heat exchange pipeline is removed, the power distribution component 150 will not leak, and there is no need to repeatedly replenish the coolant.

[0090] The water-cooled quick-change connector is divided into a pipeline joint 130 and a pipeline socket 140. The pipeline joint 130 is arranged on the base of the box body, and the pipeline socket 140 is arranged on the chassis of the power supply device 100. When the first heat exchange pipeline 210 and the cooling pipeline 110 need to be connected, the pipeline joint 130 is inserted into the pipeline socket 140.

[0091] The cooling pipeline 110 is connected to the first heat exchange pipeline 210. When the first heat exchange pipeline 210 and the cooling pipeline 110 need to be disconnected, the pipeline joint 130 is separated from the pipeline socket 140. At the same time, the pipeline joint 130 and the pipeline socket 140 are self-locking and sealed, and there is no leakage of the coolant in the cooling pipeline 110. Similarly, when the power supply device 100 needs to be connected to the power distribution assembly 150, a water-cooled quick-change connector can also be set between the power supply device 100 and the functional setting.
