Description

Technical Field

[0001] The utility model relates to the technical field of operating machinery, in particular to an operating machinery thermal management system and an operating machinery. Background Art

[0002] After the assembly of the operating machinery is completed, taking the excavator as an example, it is necessary to carry out debugging work such as liquid filling and pipeline exhaust. It can only be used normally after the debugging is qualified. Different from the traditional fuel excavator, the electric excavator needs to be filled with hydraulic oil, refrigerant and coolant in addition to not filling with fuel. Among them, when the fuel excavator is filled with coolant, it is necessary to start the machine, and the engine drives the water pump to realize the circulation of the water circuit, so as to carry out the liquid filling and exhaust work; and the water pump used in the electric excavator is different from the mechanical drive method, which is driven and controlled by an electrical signal. In addition, because the electrical signal for the operation of the water pump is provided by the controller according to the temperature requirement, when the coolant is filled, if the temperature does not reach the operating temperature of the water pump, the controller will not provide the electrical signal for the operation of the water pump. Therefore, the machine also needs to run for a period of time, and after the temperature rises, the water pump will be operated to fill the coolant. Moreover, the running and stopping time of the water pump can only be controlled according to the pre-set, and the running order of the water pumps is fixed. Therefore, the existing debugging work such as coolant filling and exhaust is time-consuming and energy-consuming, and the debugging efficiency is low. Utility Model Content

Obviously, the drawings described below are some implementation methods of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0041] Figure 2 It is a schematic structural diagram of another thermal management system for working machinery according to an embodiment of the utility model. DETAILED DESCRIPTION

[0042] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0043] In the related technology, when the vehicle is stationary, the control module obtains the number of times the vehicle's brake pedal is continuously pressed within a specified time, and makes a judgment to start the operation of the water pump based on the number of times the vehicle's brake pedal is continuously pressed within a specified time. The control module starts another water pump after starting the water pump for a set time, and the two water pumps stop running at the same time after running for a set time, thereby assisting in the filling of coolant.

[0044] In the related art, the running and stopping time of the water pump can only be controlled according to the pre-set, and the running order of the water pumps is fixed. Therefore, the existing debugging work such as coolant filling and exhaust is time-consuming and energy-consuming, and the debugging efficiency is low.

[0045] In view of this, the utility model provides a thermal management system for working machinery. After the working machinery is assembled, when it is offline for debugging or the coolant is reduced and needs to be replenished, the coolant can be replenished and the pipeline can be vented without starting the working machinery, and the water pump does not need to work according to the set operating mode, which improves the operability of the water pump and thus improves the efficiency of the debugging work.

[0046] Combine the following Figure 1 to Figure 2 , describing an embodiment of the utility model.

[0047] According to an embodiment of the present utility model, on the one hand, as Figure 1 As shown, a thermal management system for an operating machine is provided, comprising: a motor electronically controlled thermal management debugging device, comprising a first water pump and a first controller, the first controller being electrically connected to the first water pump and used to control the working state of the first water pump;

[0048] The battery thermal management debugging device comprises a second water pump and a second controller. The second controller is electrically connected to the second water pump and is used to control the working state of the second water pump.

[0049] In this embodiment, the working state of the first water pump includes the first water pump running state and the first water pump stopping state. The first water pump and the first controller in the motor electronically controlled thermal management debugging device are electrically connected; when the motor electronically controlled thermal management debugging device needs to perform a fluid replenishment operation, the first controller controls the first water pump to operate so as to perform a fluid replenishment operation for the motor electronically controlled thermal management debugging device; during the fluid replenishment process, the first water pump operates to make the liquid in the pipeline of the motor electronically controlled thermal management debugging device flow, thereby driving the flow of bubbles in the pipeline and timely discharging the gas in the pipeline; during the operation of the first water pump, the first controller can control the first water pump to stop operating at any time.

[0050] The working state of the second water pump includes the second water pump running state and the second water pump stopping state. The second water pump in the battery thermal management debugging device is electrically connected to the second controller; when the battery thermal management debugging device needs to perform a refilling operation, the second controller controls the second water pump to operate so as to perform a refilling operation for the battery thermal management debugging device; during the refilling process, the second water pump operates to make the liquid in the pipeline of the battery thermal management debugging device flow, thereby driving the flow of bubbles in the pipeline and timely discharging the gas in the pipeline; during the operation of the second water pump, the second controller can control the second water pump to stop operating at any time.

[0051] During the exhaust, i.e., the process of filling the coolant, there will be gas in the thermal management system that needs to be exhausted, so it is necessary to exhaust the gas while filling the coolant. The first water pump and the second water pump can be electronic water pumps, which are used to drive the flow of cooling media such as water to dissipate heat from the components in the operating machine. The electrical connection is preferably made by wire connection, and of course other conventional electrical connection methods can be selected as needed, which will not be listed here one by one.

[0052] In this embodiment, a motor electronically controlled thermal management debugging device and a battery thermal management debugging device are provided, so that the first controller controls the working state of the first water pump, and the second controller controls the working state of the second water pump. The first water pump and the second water pump can work independently without working according to the set operating mode, thereby improving the operability of the water pump and further improving the efficiency of the debugging work.

The first control instruction may include a first water pump operation instruction and a first water pump stop operation instruction. Since the first operation button is electrically connected to the first controller, when the first operation button is operated, the first control instruction is generated and sent to the first controller through the first operation button. If the first water pump is in a stopped state, the first controller controls the operation of the first water pump through the first control instruction; if the first water pump is in an operating state, the first controller controls the first water pump to stop operating through the first control instruction.

[0056] The second control instruction may include a second water pump operation instruction and a second water pump stop operation instruction. The second operation button is electrically connected to the second controller. When the second operation button is operated, a second control instruction is generated, and the second control instruction is sent to the second controller through the second operation button. Similarly, if the second water pump is in a stopped state, the second controller controls the operation of the second water pump through the second control instruction; if the second water pump is in an operating state, the second controller controls the second water pump to stop operating through the second control instruction. When controlling the first water pump and the second water pump, the first water pump and the second water pump can be operated or stopped at the same time; or the first water pump can be controlled to operate and the second water pump can be controlled to stop; or the first water pump can be controlled to stop and the second water pump can be controlled to operate. How to control the operation of the water pump can be selected by yourself during actual operation.

There is no need to start the operating machinery, and the working state of the water pump is controlled only by the operating buttons. This can avoid the operating machinery from performing fluid replenishment operations when it is in a high-pressure operating state and prevent the problem of violent splashing of liquid due to excessive pressure, thereby reducing energy consumption and improving operating safety.

[0060] By setting the first touch key and the second touch key on the display panel, this embodiment can effectively reduce the space required for physical buttons inside the working machine, make the internal appearance of the working machine more simple and beautiful, and improve the overall texture. It also allows the user to operate directly on the display panel without having to look for buttons in other locations inside the working machine, thereby improving the convenience of operation.

After entering the operation page of the first touch key and the second touch key, the first touch key and the second touch key are allowed to be operated, and the first controller and the second controller can respond according to the specific operation. By setting an encryption module in the display panel, only debugging and service personnel are allowed to enter the touch key operation page to operate, thereby preventing the irregular use of function keys.

[0063] In one embodiment, the thermal management system for the operating machine further includes: a first timing module, electrically connected to the first controller and the first water pump, respectively, for calculating the operating time of the first water pump;

[0064] The second timing module is electrically connected to the second controller and the second water pump respectively, and is used to calculate the operating time of the second water pump.

[0065] In this embodiment, the first timing module is electrically connected to the first controller and the first water pump respectively. After receiving the first control instruction sent by the first operation button, the first controller controls the first water pump to operate, and the first timing module starts to calculate the operating time of the first water pump; a preset operating time T is stored in the first timing module. 1 , when the running time of the first water pump meets the stored preset running time T 1 After that, the first controller controls the first water pump to stop running, and it can be seen on the display panel that the first water pump stops running.

[0066] The second timing module is electrically connected to the second controller and the second water pump respectively. After receiving the second control instruction sent by the second operation button, the second controller controls the second water pump to operate, and the second timing module starts to calculate the operating time of the second water pump; a preset operating time T is stored in the second timing module. 2 , when the running time of the second water pump meets the stored preset running time T 2 After that, the second controller controls the second water pump to stop running, and it can be seen on the display panel that the second water pump stops running.

[0067] In this embodiment, the first timing module and the second timing module are set to calculate the operating time of the first water pump and the second water pump. After the operating time is reached, the first water pump and the second water pump automatically stop, thereby ensuring that the first water pump and the second water pump work for the required time, reducing the uncertainty of manual operation, simplifying the operation, and saving energy.

[0068] It should be noted that the first timing module can be built in the first controller, and the second timing module can be built in the second controller, and the first timing module and the second timing module can be ordinary timers. The positions of the first timing module and the second timing module are not limited here.

[0069] In other embodiments, during the operation of the first water pump, the first operation button can be operated at any time; after the first operation button is operated, the first operation button sends the first water pump stop operation instruction to the first controller, the first controller controls the first water pump to stop running, and feeds back the first water pump stop operation signal to the display panel.

[0070] During the operation of the second water pump, the second operation button can also be operated at any time; after operating the second operation button, the second operation button sends the second water pump stop operation instruction to the second controller, the second controller controls the second water pump to stop running, and feeds back the second water pump stop operation signal to the display panel.

[0071] Of course, the first operation button and the second operation button may also be buttons, and can also achieve the same operation, which is not specifically limited here.

[0072] In one of the embodiments, the thermal management system of the operating machine further includes: a first water tank connected to the first water pump; and a second water tank connected to the second water pump.

[0073] In this embodiment, the first water tank and the second water tank are used to store coolant. When there is a lack of coolant in the motor electronic control thermal management debugging device, the coolant is pumped out from the first water tank by running the first water pump and transferred to the motor electronic control thermal management debugging device to replenish the coolant; at the same time, the first water pump drives the coolant to flow in the pipeline, thereby driving the flow of bubbles in the pipeline and timely discharging the gas in the pipeline. When there is a lack of coolant in the battery thermal management debugging device, the coolant is pumped out from the second water tank by running the second water pump and transferred to the motor electronic control thermal management debugging device to replenish the coolant; at the same time, the second water pump drives the coolant to flow in the pipeline, thereby driving the flow of bubbles in the pipeline and timely discharging the gas in the pipeline. By setting the first water tank and the second water tank, sufficient coolant can be provided for the operating machinery thermal management system to ensure the normal operation of the system, and it can also help absorb and store heat so that the system can regulate the temperature more effectively.

[0074] In one embodiment, both the first water tank and the second water tank are expansion water tanks. There will be pressure fluctuations in the entire thermal management system. When the liquid in the thermal management system is heated, the thermal motion of the liquid molecules is enhanced, and the distance between the liquid molecules becomes larger, which causes the volume of the liquid to expand. If there is no place to accommodate this part of the expansion, the liquid pressure in the thermal management system will increase, thereby affecting the normal operation of the thermal management system. At this time, the expansion water tank can accommodate the liquid expansion of the thermal management system, reduce the liquid pressure fluctuations caused by the expansion of the liquid in the thermal management system, improve the safety and reliability of the operation of the thermal management system, and make the thermal management more stable.

[0075] In addition, when the thermal management system cools down, the liquid level in the expansion tank will drop to replenish the thermal management system.

The second cooling circuit passes through the heat-generating components in the battery thermal management debugging device, and is used to cool the heat-generating components in the battery thermal management debugging device; the second water pump pumps the coolant from the second water tank into the second cooling circuit, and the coolant flows in the second cooling circuit to take away the heat of the heat-generating components in time to cool the heat-generating components.

Independent temperature control and debugging are performed according to different needs, which improves the flexibility and reliability of the thermal management system.

[0079] It should be noted that this embodiment does not improve the programs of the controllers, and the electronic control operation functions of the controllers are all existing functions.

[0081] Battery pack, motor and the above-mentioned operating machinery thermal management system. The battery thermal management debugging device is used to cool the battery pack, and the motor electronic control thermal management debugging device is used to cool the motor.

By cooling the battery pack with the battery thermal management debugging device and cooling the motor and motor controller with the motor electronic control thermal management debugging device, heat can be removed from the battery pack and the motor in time, keeping the battery pack and the motor operating within a suitable temperature range, making the operation of the operating machinery more reliable and stable.

[0082] The working machinery of the embodiment of the utility model may be an excavator, a forklift, a grader, etc., and the working machinery of the embodiment of the utility model may be a vehicle with an electric, fuel or hybrid power system, which is not specifically limited here.

[0084] In this embodiment, the coolant in the first water tank flows into the cooling channel in the motor through the first cooling circuit, and the flowing coolant absorbs the heat emitted by the motor and takes the heat away to cool the motor. The coolant in the second water tank flows into the cooling channel in the battery pack through the second cooling circuit, and the flowing coolant absorbs the heat emitted by the battery pack and takes the heat away to cool the battery pack.
