Description

Technical Field

[0001] The present invention relates to the field of steering motor temperature regulation, and particularly to a temperature regulation device and a control method for a steering motor and its connecting wire harness. Background Art

[0002] When a current traditional vehicle is running, the engine generates a large amount of heat, resulting in frequent thermal damage problems of the engine compartment electronic components and wire harnesses. When the electronic components and wire harnesses work in a high-temperature environment for a long time, it will accelerate their aging and affect the service life, and even cause failures and affect driving safety. Therefore, it is necessary to lower the temperature in the engine compartment in time to ensure that the components of each system work at an appropriate temperature.

[0003] In order to consider the aesthetics of the engine compartment, an engine decorative cover and an engine compartment decorative cover are generally added to the upper part of the engine compartment to cover the pipelines. At the same time, in order to reduce wind resistance, an engine underbody panel is added to the lower part of the engine compartment, and the entire engine compartment is sealed, resulting in poor heat dissipation of the engine compartment.

[0004] In actual use, affected by the engine compartment ambient temperature, the engine has been working at a high temperature, which will cause the steering motor to overheat and be difficult to provide steering assistance, thus having a great impact on safe driving. At the same time, the steering motor wire harness will age and even be baked and fail in a high-temperature environment for a long time, posing a certain safety risk in use. Summary of the Invention

[0005] The present application provides a temperature regulation device for a steering motor and its connecting wire harness, which can solve the technical problem of overheating of the steering motor in the engine compartment due to poor heat dissipation performance in the prior art.

[0006] In a first aspect, an embodiment of the present application provides a temperature regulation device for a steering motor and its connecting wire harness, which includes:

[0007] A heat exchange device, which is used to be installed in the engine compartment and can form a heat exchange with the engine compartment environment;

[0008] A condenser, which is connected to the heat exchange device;

[0009] And a controller, which is communicated with the heat exchange device and the condenser and is used to control the heat exchange device and the condenser to be turned on or off.

[0010] By adopting the above technical solution, the controller turns on the heat exchange device and the condenser. The condenser continuously provides a low-temperature source for the heat exchange device, enabling the heat exchange device to form a heat exchange with the air in the engine room environment, thereby reducing the ambient temperature in the engine room, improving the heat dissipation performance in the engine room, and further reducing the possibility of overheating of the steering motor and its connecting wire harness, solving the problem of overheating of the steering motor in the engine room caused by poor heat dissipation performance in the engine room.

[0011] Combined with the first aspect, in one embodiment, the heat exchange device includes:

[0012] An expansion valve, which is connected to the controller;

[0013] A heat exchange tube, both ends of the heat exchange tube are connected to the expansion valve, and both ends of the heat exchange tube are respectively connected with a high-pressure tube and a low-pressure tube through the expansion valve, and the high-pressure tube is communicated with the condenser;

[0014] And a compressor, which is communicated with the low-pressure tube, and the compressor is connected to the condenser and the controller.

[0015] By adopting the above technical solution, the low-temperature high-pressure liquid in the condenser flows from the high-pressure tube to the expansion valve. The expansion valve transforms the low-temperature high-pressure liquid in the high-pressure tube into a low-temperature low-pressure liquid and enters the heat exchange tube. The low-temperature low-pressure liquid flows in the heat exchange tube and exchanges heat with the air in the engine room, reducing the temperature in the engine room. The heat exchange tube absorbs heat, causing the low-temperature low-pressure liquid in the heat exchange tube to absorb heat and vaporize into a low-pressure gas; the low-pressure gas then passes through the expansion valve, is transformed into a low-pressure liquid in the expansion valve and enters the low-pressure tube and flows into the compressor, and is compressed by the compressor into a high-pressure liquid and flows into the condenser, and is re-converted into a low-temperature high-pressure liquid in the condenser. In this cycle, a low-temperature source is continuously supplied to the engine room for heat exchange, without the need to install an additional temperature control device, and it can be recycled, which is more convenient.

[0016] Combined with the first aspect, in one embodiment, the heat exchange tube is provided with heat sinks.

[0017] By adopting the above technical solution, the heat sinks are fixed on the outer wall of the heat exchange tube. By increasing the additional surface area, the contact area between the heat exchange tube and the surrounding environment is further enlarged, enabling the heat exchange tube to more effectively absorb or release heat from the engine room, thus significantly improving the heat exchange efficiency.

[0018] Combined with the first aspect, in one embodiment, a temperature regulating device for a steering motor and its connecting wire harness further includes:

[0019] A cooling fan, which is connected to the controller.

[0020] By adopting the above technical solution, the cooling fan can accelerate the air flow in the engine compartment to blow the cold air of the heat exchange device towards the steering motor and its connecting wire harness, which can not only deliver cold air towards the steering motor and its connecting wire harness, but also take away the heat of the steering motor and its connecting wire harness, further accelerating the cooling of the steering motor and its connecting wire harness.

[0021] Combined with the first aspect, in an embodiment, a fixing bracket is provided on the cooling fan.

[0022] By adopting the above technical solution, the cooling fan is arranged on the connecting device of the steering motor through the fixing bracket, so that the cooling fan can be installed more stably.

[0023] Combined with the first aspect, in an embodiment, a wind guard is further installed outside the cooling fan.

[0024] By adopting the above technical solution, the wind guard can enable the cooling fan to form a simple air outlet duct, which plays a role in gathering and guiding the air outlet of the cooling fan, improving the concentration and flow rate of the air outlet, and further enhancing the cooling efficiency. At the same time, the wind guard can also effectively block external dust and debris from entering the interior of the cooling fan, protect its normal operation, and extend its service life.

[0025] Combined with the first aspect, in an embodiment, a temperature regulating device for a steering motor and its connecting wire harness further includes:

[0026] A temperature sensor, the temperature sensor is connected to the controller, and the temperature sensor is used to be arranged in the engine compartment and can detect the temperature of the engine compartment environment.

[0027] By adopting the above technical solution, the temperature sensor is connected to the controller to transmit the ambient temperature in the engine compartment to the controller in real time, facilitating the operator to timely turn on the heat exchange device and the cooling fan through the controller to take cooling measures in the engine compartment, effectively reducing the situation that the temperature in the engine compartment is too high and the steering motor and its connecting wire harness are overheated.

[0028] Combined with the first aspect, in an embodiment, a temperature threshold is set in the controller;

[0029] When the real-time temperature detected by the temperature sensor is greater than or equal to the temperature threshold, the controller controls the heat exchange device and the condenser to be turned on;

[0030] When the real-time temperature detected by the temperature sensor is less than the temperature threshold, the controller does not turn on the heat exchange device and the condenser.

[0031] By adopting the above technical solutions, the automation function of the temperature regulation device is further enhanced. This not only greatly reduces the burden of manual monitoring, enabling the operator not to constantly pay attention to the temperature changes in the engine room, so that more energy can be devoted to other important tasks, but also significantly improves the response speed and accuracy of the temperature regulation of the steering motor and its connecting wire harness, enabling the equipment in the engine room to operate stably in the most suitable temperature environment.

[0032] Combined with the first aspect, in an embodiment, the controller is used to be linked with the vehicle air conditioning system. When the vehicle air conditioning system is turned on, the controller controls the heat exchange device and the condenser to be turned on.

[0033] By adopting the above technical solutions, when the outside temperature is relatively high and the operator in the cab turns on the vehicle air conditioning system, the controller synchronously turns on the heat exchange device and the condenser to synchronously cool the steering motor and its connecting wire harness, thereby effectively preventing the environmental temperature in the engine room from being too high.

[0034] In a second aspect, an embodiment of the present application provides a control method for a temperature regulation device of a steering motor and its connecting wire harness, which includes:

[0035] Obtain the real-time temperature in the engine room and compare it with the temperature threshold in the controller;

[0036] If the real-time temperature in the engine room is greater than or equal to the temperature threshold in the controller, the controller controls the heat exchange device and the condenser to be turned on and forms a heat exchange with the engine room environment in the engine room;

[0037] If the real-time temperature in the engine room is less than the temperature threshold in the controller, the controller does not turn on the heat exchange device and the condenser.

[0038] By adopting the above technical solutions, the operator can turn on the controller according to the real-time temperature in the engine room, or directly set the control machine to the mode of automatically turning on when the temperature threshold is exceeded. When the controller controls the condenser and the heat exchange device to start simultaneously, the heat exchange device exchanges heat with the temperature of the engine room environment, reducing the environmental temperature in the engine room, improving the heat dissipation performance in the engine room, and further reducing the possibility of overheating of the steering motor and its connecting wire harness, solving the problem of overheating of the steering motor in the engine room caused by poor heat dissipation performance in the engine room.

[0039] The beneficial effects brought by the technical solutions provided by the embodiments of the present application include:

[0040] By installing a heat exchange device and a condenser in the engine compartment, the condenser can continuously provide a low-temperature source for the heat exchange device. The controller is connected to the heat exchange device. When the controller controls the condenser and the heat exchange device to start simultaneously, the heat exchange device exchanges heat with the temperature of the engine compartment environment, reducing the ambient temperature in the engine compartment, improving the heat dissipation performance in the engine compartment, and further reducing the possibility of overheating of the steering motor and its connecting wire harness, thus solving the problem of overheating of the steering motor in the engine compartment due to poor heat dissipation performance in the engine compartment.

[0046] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0047] The embodiment of the present application provides a temperature regulating device for a steering motor and its connecting wire harness, which can solve the problem of overheating of the steering motor in the engine compartment due to poor heat dissipation performance in the engine compartment.

[0048] The embodiment of the present application is described in the state where the temperature regulating device has been installed in the engine compartment. Refer toFigure 1 Schematic diagram of the installation of a temperature regulation device for a steering motor and its connecting wire harness in the engine compartment in an embodiment of the present application. A temperature regulation device for a steering motor 4 and its connecting wire harness 42 disclosed in the present application includes a heat exchange device, a condenser 2, and a controller. The heat exchange device is installed in the engine compartment and is located beside the steering motor 4 and its connecting wire harness 42, and forms a heat exchange with the air in the engine compartment environment, thereby reducing the ambient temperature in the engine compartment; the condenser 2 is connected to the heat exchange device and continuously provides a low-temperature source for the heat exchange device, so that the heat exchange device can continuously perform heat exchange with the air in the engine compartment environment when starting, thereby reducing the ambient temperature in the engine compartment and achieving a heat dissipation effect. The controller is communicated with the heat exchange device and the condenser 2 and is used to control the opening or closing of the heat exchange device and the condenser 2.

[0049] When the temperature in the engine compartment gradually rises due to factors such as the long-term operation of the steering motor 4 and its connecting wire harness 42 or the high temperature of the external environment, the operator can turn on the heat exchange device and the condenser 2 through the controller. The condenser 2 provides a low-temperature source for the heat exchange device, so that the heat exchange device performs heat exchange with the engine compartment environment, reduces the ambient temperature in the engine compartment, improves the heat dissipation performance in the engine compartment, and further reduces the possibility of overheating of the steering motor 4 and its connecting wire harness 42, solving the problem of overheating of the steering motor 4 in the engine compartment caused by poor heat dissipation performance in the engine compartment.

[0050] In actual installation settings, the controller can be linked with the vehicle's air conditioning system. When the external temperature is high and the operator in the cab turns on the vehicle's air conditioning system, the controller synchronously turns on the heat exchange device and the condenser 2 to synchronously cool the steering motor 4 and its connecting wire harness 42, thereby effectively preventing the ambient temperature in the engine compartment from being too high.

[0051] More specifically, referring to Figure 1 Schematic diagram of the installation of a temperature regulation device for a steering motor and its connecting wire harness in the engine compartment in an embodiment of the present application and Figure 2 Connection structure diagram at the heat exchange pipe in an embodiment of the present application. The heat exchange device includes an expansion valve 11, a heat exchange pipe 1, and a compressor 12. The expansion valve 11 is connected to the controller and can receive the opening signal from the controller; both ends of the heat exchange pipe 1 are respectively connected with a high-pressure pipe 112 and a low-pressure pipe 111. The high-pressure pipe 112 and the low-pressure pipe 111 are both connected to the expansion valve 11. The high-pressure pipe 112 is connected to the condenser 2 through the expansion valve 11, and the low-pressure pipe 111 is connected to the compressor 12 through the expansion valve 11. The compressor 12 is also connected to the controller.

[0052] Among them, the expansion valve 11, also known as the throttle valve or expander, is a key component in the heat exchange device. The expansion valve 11 is a device that controls the refrigerant flow by changing the cross-sectional area of the passage, enabling the medium-temperature and high-pressure liquid refrigerant to throttle through the expansion valve 11 into a low-temperature and low-pressure wet steam. Then the refrigerant absorbs heat in the evaporator, thus achieving the refrigeration effect. The working principle of the compressor 12 is mainly to convert the rotational motion of the compressor 12 motor into the translational motion of the piston through the crank connecting rod mechanism inside the compressor 12. The translational motion of the piston causes the volume of the cylinder compression chamber inside the compressor 12 to change periodically, thereby compressing the gas volume inside the compressor 12 and increasing its pressure, so that the compressor 12 sucks in the low-temperature and low-pressure refrigerant gas from the suction pipe, and then drives the piston through the motor operation to compress the low-temperature and low-pressure refrigerant gas, and discharges the high-temperature and high-pressure refrigerant gas (or liquid) to the exhaust pipe, providing power for the refrigeration cycle.

[0053] When the controller turns on the heat exchange device and the condenser 2, the low-temperature and high-pressure liquid in the condenser 2 flows from the high-pressure pipe 112 to the expansion valve 11. The expansion valve 11 converts the low-temperature and high-pressure liquid in the high-pressure pipe 112 into a low-temperature and low-pressure liquid and enters the heat exchange pipe 1. The low-temperature and low-pressure liquid flows in the heat exchange pipe 1 and exchanges heat with the air in the engine room, reducing the temperature in the engine room. The heat absorption of the heat exchange pipe 1 causes the low-temperature and low-pressure liquid in the heat exchange pipe 1 to absorb heat and vaporize into a low-pressure gas; the low-pressure gas then passes through the expansion valve 11, turns into a low-pressure liquid in the expansion valve 11 and enters the low-pressure pipe 111 and flows into the compressor 12, and is compressed by the compressor 12 into a high-pressure liquid and flows into the condenser 2, and is re-converted into a low-temperature and high-pressure liquid in the condenser 2. In this cycle, a low-temperature source is continuously supplied to the engine room and heat exchange is carried out. There is no need to install an additional temperature control device, and it can be recycled, which is more convenient.

[0054] More specifically, referring to Figure 2 , heat dissipation fins 13 are also provided on the heat exchange pipe 1. The heat dissipation fins 13 are fixed on the outer wall of the heat exchange pipe 1, and further expand the contact area between the heat exchange pipe 1 and the surrounding environment by increasing the additional surface area. This design enables the heat exchange pipe 1 to more effectively absorb or release heat from the engine room, thus significantly improving the heat exchange efficiency. During the actual installation process, the number and distribution of the heat dissipation fins 13 can be optimized according to specific requirements to achieve the best heat exchange effect.

[0055] The heat sink 13 can be made of aluminum alloy material. Aluminum alloy material is famous for its excellent thermal conductivity and light weight, which makes it an ideal choice for manufacturing the heat sink 13. The thermal conductivity of aluminum alloy is much higher than that of many other common materials, so it can transfer heat faster, thereby further assisting the heat exchange tube 1 to conduct efficient heat exchange with the surrounding ambient temperature. In addition, the aluminum alloy material also has good corrosion resistance and workability, making the heat sink 13 more reliable and durable during manufacturing and use. In addition, the heat exchange tube 1 itself also adopts advanced manufacturing processes and materials to enable the heat exchange tube 1 to withstand the sealed working environment in the engine compartment and maintain long-term stability and reliability, extending its service life.

[0056] In order to further accelerate the cooling rate of the steering motor 4, a cooling fan 3 is also installed in the temperature regulating device. The cooling fan 3 is also connected to the controller. The air outlet direction of the cooling fan 3 faces the steering motor 4 and its connecting wire harness 42. And during installation, the cooling fan 3 can be arranged between the steering motor 4 and its connecting wire harness 42 and the heat exchange device, so that the cooling fan 3 can accelerate the air flow in the engine compartment to blow the cold air of the heat exchange device towards the steering motor 4 and its connecting wire harness 42, which can not only deliver cold air towards the steering motor 4 and its connecting wire harness 42, but also take away the heat of the steering motor 4 and its connecting wire book, further accelerating the cooling of the steering motor 4 and its connecting wire harness 42.

[0057] The cooling fan 3 is also connected to the controller. The cooling fan 3 can be set to be turned on synchronously with the heat exchange device and the condenser 2. When the controller turns on the heat exchange device, the cooling fan 3 is turned on synchronously to play an efficient heat dissipation role for the steering motor 4 and its connecting wire harness 42, and improve the intelligent management of the overall control, making it more convenient to use. In other embodiments, considering the energy consumption requirements in different application scenarios, the cooling fan 3 can also be set to an independent startup mode to save electric energy. In some cases, such as when the heat exchange and dissipation capabilities of the heat exchange device and the condenser 2 are sufficient to reduce the ambient temperature in the engine compartment, or when the ambient temperature in the engine compartment is relatively low, the cooling fan 3 can be selected not to start or start with a delay, so as to minimize unnecessary power consumption while ensuring the heat dissipation effect. The specific setting method of the cooling fan 3 can be connected according to actual needs.

[0058] The cooling fan 3 is an important auxiliary heat dissipation device for the steering motor 4 and its connecting wire harness 42. The optimization of its installation stability and air outlet efficiency is particularly important. Therefore, referring to Figure 1 Schematic diagram of the installation structure of a temperature regulating device for a steering motor and its connecting wire harness in an embodiment of the present application in the engine compartment and Figure 3Schematic diagram of the structure of the cooling fan in the embodiment of the present application. An additional fixing bracket 31 is also provided on the cooling fan 3. The cooling fan 3 is arranged on the connecting device of the steering motor 4 through the fixing bracket 31, so that the cooling fan 3 can be installed more stably. In addition, the fixing bracket 31 not only provides necessary support for the cooling fan 3, but also can assist in defining the air outlet direction of the cooling fan 3, so that the air outlet direction of the cooling fan 3 can always accurately face the steering motor 4 and its connection harness 42, thereby ensuring the effective discharge of heat.

[0059] Furthermore, a wind guard 32 is additionally provided outside the cooling fan 3 to enable the cooling fan 3 to form a simple air outlet duct, which plays a role in gathering and guiding the air outlet of the cooling fan 3, improving the concentration and flow rate of the air outlet, and further enhancing the cooling efficiency. At the same time, the wind guard 32 can also effectively block external dust and debris from entering the interior of the cooling fan 3, protect its normal operation, and extend its service life.

[0060] In order to facilitate the operator in the cab to judge whether it is necessary to cool and dissipate heat in the engine room, the temperature adjustment device further includes a temperature sensor 14. The temperature sensor 14 is arranged in the engine room and is used to detect the ambient temperature in the engine room. The temperature sensor 14 is connected to the controller to transmit the ambient temperature in the engine room to the controller in real time, so that the operator can timely turn on the heat exchange device and the cooling fan 3 through the controller to take cooling measures for the engine room, effectively reducing the situation that the steering motor 4 and its connection harness 42 are overheated due to too high temperature in the engine room.

[0061] In order to further enhance the automation function of the temperature adjustment device, a temperature threshold is set in the controller. When the real-time temperature detected by the temperature sensor 14 is greater than or equal to the temperature threshold in the controller, the controller controls the heat exchange device, the condenser 2 and the cooling fan 3 to turn on, eliminating the need for manual monitoring of the temperature in the engine room at all times, which is more convenient to use. This automated operation not only greatly reduces the burden of manual monitoring, enabling the operator not to constantly pay attention to the temperature changes in the engine room, so that more energy can be devoted to other important tasks, but also significantly improves the response speed and accuracy of the temperature adjustment of the steering motor 4 and its connection harness 42, enabling the equipment in the engine room to operate stably in the most suitable temperature environment. Therefore, this highly automated temperature adjustment mechanism can prevent the steering motor 4 and its connection harness 42 from malfunctioning or degrading in performance due to too high engine room temperature, providing a strong guarantee for the long-term stable operation of the equipment in the engine room.

[0062] Based on the above temperature adjustment device for a steering motor and its connection harness, the present application also proposes a control method for the temperature adjustment device for a steering motor and its connection harness, which includes the following steps:

[0063] S1: Preset a temperature threshold in the controller, obtain the real-time temperature in the engine room, and compare it with the temperature threshold in the controller. The controller determines whether to turn on the heat exchange device and the condenser.

[0064] S2: If the real-time temperature in the engine room is greater than or equal to the temperature threshold in the controller, the controller controls the heat exchange device and the condenser to turn on, and a heat exchange is formed between the engine room and the engine room environment.

[0065] S3: If the real-time temperature in the engine room is less than the temperature threshold in the controller, the controller does not turn on the heat exchange device and the condenser.
