Description

Technical Field

[0001] This application relates to the field of new energy vehicles, and more specifically, to an electronic valve and an electronic valve system. Background Technology

[0002] like Figure 1 As shown, thermal management systems in new energy vehicles typically employ multiple electronic valves. The vehicle collects real-time temperatures from the drive motor, battery, and passenger compartment, analyzes their thermal demands, and adjusts the flow rate to various locations via these electronic valves to maintain ideal temperature environments for the motor, battery, and passenger compartment, thus achieving efficient energy utilization. In existing thermal management systems for new energy vehicles, each electronic valve is an independent unit. If the vehicle needs to change the direction of the cooling circuit, control commands must be sent to each electronic valve separately. This requires each electronic valve to have its own independent control circuit board to receive command signals and drive the actuators within it. This type of system has high control costs and a complex control system. Summary of the Invention

[0005] This application embodiment connects the auxiliary electronic valve to the main electronic valve, and uses functions provided on the main electronic valve to control the working state of the auxiliary electronic valve (e.g., these functions include parsing main valve command information and auxiliary valve command information from the host computer to obtain position data (i.e., position data characterizing the final rotation state of the motor on the main electronic valve or the auxiliary electronic valve) and action data (e.g., initializing the main electronic valve or the auxiliary electronic valve); and controlling the on / off of the power supply to the motor on the main electronic valve or the auxiliary electronic valve based on the position data and the feature values ​​from the auxiliary electronic valve).

[0008] In some embodiments, the controller includes: a plurality of control ports configured to: be connected to the vehicle control device to receive the main valve command signal and the auxiliary valve command signal; and be connected to the auxiliary electronic valve to receive the characteristic value from the auxiliary electronic valve or to control the power supply of the auxiliary electronic valve to be turned on or off.

[0009] In this embodiment, the auxiliary electronic valve and the main electronic valve are connected by a wire, achieving bidirectional communication between the main electronic valve and the auxiliary electronic valve.

[0010] In some embodiments, the control port is connected to the secondary electronic valve via multiple MOS ports.

[0011] The embodiments of this application can make full use of the idle MOS ports on the main electronic valve control circuit board to connect with the auxiliary electronic valve, thereby simplifying the control system and reducing control costs.

[0012] In some embodiments, the main electronic valve and the auxiliary electronic valve are connected wirelessly.

[0013] The embodiments of this application establish the connection between the main electronic valve and the auxiliary electronic valve wirelessly, thereby simplifying and reducing the number of electronic valve system connections and simplifying the control system structure.

[0014] In some embodiments, the secondary electronic valve includes: an actuator configured to receive control from the primary electronic valve to switch the flow path of the secondary valve or to adjust the flow rate proportionally; and a Hall sensor configured to acquire the characteristic value characterizing the rotational state of the motor.

[0015] The auxiliary electronic valve in this embodiment has a simple structure because it does not need to parse control commands from the host computer or determine whether to supply power to the motor based on the characteristic values ​​of the collected motor status, thus simplifying the structure of the auxiliary electronic valve.

[0016] In some embodiments, the actuator includes a motor, a gear train, and a valve core; wherein the motor drives the gear train to rotate, and the gear train further drives the valve core to rotate, thereby completing the switching of the flow channel and the adjustment of the flow ratio.

[0017] The embodiments of this application use an actuator composed of a motor, gear system and valve core to perform the functions of switching the flow channel and adjusting the flow ratio.

[0018] In some embodiments, the main electronic valve is a four-way electronic valve, and the auxiliary electronic valve is a three-way electronic valve; wherein, when the flow channel is a cooling system flow channel, the four-way electronic valve is at least configured to switch the flow direction of the medium in the cooling system, and the three-way electronic valve is at least configured to control the flow direction and flow rate ratio adjustment of the medium in the cooling system.

[0019] The embodiments of this application can be applied to four-way electronic valves and three-way electronic valves, simplifying the control structure of three-way electronic valves.

[0033] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0034] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] Electronic valves in new energy vehicles include various types, such as electronic water valves, electronic oil valves, and electronic expansion valves. The main electronic valve and auxiliary electronic valve involved in the embodiments of this application belong to one type of electronic valve.

[0036] Electronic water valves, electronic oil valves, and electronic expansion valves each regulate the following media: antifreeze, oil, and refrigerant, respectively. For example, in the water circulation system of new energy vehicles (please refer to...). Figure 1 It will be equipped with multiple electronic valves. Figure 1 The electronic valves 120, 230, and 320 shown are used to analyze the heat demand of the vehicle by collecting real-time temperatures of the drive motor 100, battery 200, and passenger compartment 300, and then controlling these temperatures through the electronic valves. Figure 1 The electronic valves 120, 230, and 320 shown regulate the flow to various locations, ensuring that the drive motor 100, battery 200, and cockpit 300 are in an ideal temperature environment, thus achieving efficient energy utilization. Figure 1 In the thermal management system of new energy vehicles, each electronic valve ( Figure 1 The electronic valves 120, 230, and 320 shown are all independent units. If the vehicle needs to change the direction of the cooling circuit, the vehicle control unit 400 needs to control each electronic valve separately. Figure 1 The electronic valves 120, 230, and 320 shown send control command signals, which are then parsed by the controllers (1201, 2301, 3201) on the electronic valves. This requires each electronic valve ( Figure 1 Each of the electronic valves 120, 230, and 320 shown has an independent control circuit board for receiving command signals from the vehicle control unit 400 and driving the actuators (1202, 2302, 3202) within each electronic valve. This control system is relatively complex and expensive.

[0037] like Figure 2 As shown, this application embodiment provides an electronic valve system, which includes: a main electronic valve 10, configured to parse command signals from a vehicle control device and control the switching of the main electronic valve's flow path or the adjustment of the flow ratio; and at least one auxiliary electronic valve (i.e., Figure 2 The first auxiliary electronic valve 20 and the second auxiliary electronic valve 30 shown are configured to be connected to the main electronic valve; wherein the main electronic valve receives feature values ​​collected by the auxiliary electronic valve through the connection, and controls the operating state of the auxiliary electronic valve according to the feature values. For example, controlling the operating state of the auxiliary electronic valve can be to continue supplying power to the auxiliary electronic valve or to cut off power. For example, the feature values ​​can be parameter values ​​characterizing the rotation state of the motor on the auxiliary electronic valve.

[0038] The electronic valve system of this application embodiment can be applied to the above-mentioned electronic water valve system, electronic oil valve system, and electronic expansion valve system. That is, in this application embodiment, multiple electronic water valves of the electronic water valve system can be respectively configured as a main electronic water valve and an auxiliary electronic water valve, and multiple electronic oil valves of the electronic oil valve system can be respectively configured as a main electronic oil valve and an auxiliary electronic oil valve.

[0039] The command signal in this embodiment of the application may be a vehicle control device 400 (e.g., Figure 3 The vehicle control unit 400 receives signals from a host computer (not shown in the figure). These command signals are primarily used to characterize the final adjustment position of the motor connected to the main electronic valve or the auxiliary electronic valve. For example, with... Figure 1 For example, assuming the host computer determines the final adjustment position of the motors connected to each electronic valve by collecting the temperature of the battery or cockpit. This embodiment uses the main electronic valve 10 to analyze the parameters of the main electronic valve 10 and the auxiliary electronic valves (e.g.,...). Figure 2 The system obtains position information (i.e., position data characterizing the final rotational state of the motor on the main electronic valve or the auxiliary electronic valve) and action name (e.g., initialization of the main electronic valve or the auxiliary electronic valve) from all command information of the first auxiliary electronic valve 20 and the second auxiliary electronic valve 30 shown. Based on the position information and characteristic values, the system controls the actuator of the main electronic valve itself or the actuator on the auxiliary electronic valve to perform the main electronic valve flow channel or auxiliary valve flow channel switching related actions.

[0040] This application embodiment also requires sensors to collect the operating status (e.g., speed or direction of rotation) of the motors on the main electronic valve or each auxiliary electronic valve in real time or periodically. The collected rotational states of these motors are used as the aforementioned feature values. Then, the main electronic valve determines the next action of the motor based on these feature values ​​and the position data obtained after parsing the command signal, that is, whether to continue to power on or de-power the motors on the main electronic valve or the auxiliary electronic valves. In some examples, the motor located on the main electronic valve can be referred to as the main valve motor, and the motor located on the auxiliary electronic valve is referred to as the auxiliary valve motor.

[0041] In this embodiment of the application, the main electronic valve flow channel refers to the flow channel controlled by the main electronic valve, and the secondary valve flow channel is the flow channel controlled by the secondary electronic valve.

[0042] It should be noted that, Figure 2 and Figure 3 The main electronic valve 10 and the auxiliary electronic valve shown (e.g., Figure 2 and Figure 3 The first electronic valve 20 and the second electronic valve 30 can be connected either wired or wirelessly. Although Figure 2 and Figure 3Only two auxiliary electronic valves are shown, but the embodiments of this application do not limit the number of auxiliary electronic valves. For example, in some examples, the number of auxiliary electronic valves may be more than two, or there may be only one. In other examples, the electronic valve system may also include multiple main electronic valves, each of which is connected to at least one auxiliary electronic valve.

[0043] The command signals in this embodiment include a main valve command signal and a secondary valve command signal. The main electronic valve 10 may include: a controller configured to: receive the main valve command signal and the secondary valve command signal from the vehicle control device, and parse the main valve command signal and the secondary valve command signal; acquire characteristic values ​​of the main valve motor, and control the working state of the main valve motor according to the characteristic values; receive characteristic values ​​from the secondary electronic valve, and control the working state of the secondary electronic valve by controlling the on or off of the power supply according to the characteristic values; and an actuator configured to switch the flow channel of the main electronic valve or adjust the flow ratio.

[0044] The feature values ​​in this application embodiment include both the feature values ​​related to the rotation state of the motor controlled by the main electronic valve, which are collected by the information acquisition unit (e.g., Hall sensor) on the main electronic valve, and the feature values ​​of the rotation state of the motor controlled by the auxiliary electronic valves, which are collected by the acquisition units (e.g., Hall sensors) on each auxiliary electronic valve, which are received by the main electronic valve.

[0045] This application embodiment can determine whether the motors connected to the main electronic valve and the auxiliary electronic valve should continue to rotate or stop working based on feature values ​​and position data obtained after parsing command signals, and ultimately realize the switching of the main valve or auxiliary valve flow channel or the flow ratio adjustment. For example, based on the feature values ​​collected by the main electronic valve or the auxiliary electronic valve at the current moment, it is determined whether the motor has rotated to the final position represented by the position data at the current moment, and whether to continue to power the motor or not is determined based on whether it has rotated to the final position. For example, if the first motor has rotated to the final position, the power supply to the first motor is stopped; otherwise, the power supply to the first motor continues.

[0046] In this embodiment, the controller on the main electronic valve 10 includes multiple control ports configured to: connect to the vehicle control device to receive the main valve command signal and the auxiliary valve command signal; and connect to the auxiliary electronic valve to receive the characteristic value from the auxiliary electronic valve or control the power supply of the auxiliary electronic valve to turn on or off. For example, the control ports are connected to the auxiliary electronic valve through multiple MOS ports.

[0047] The following is combined Figure 4 , Figure 5 as well as Figure 6 The structure of the main electronic valve 10 is illustrated by way of example.

[0048] Figure 4 The main electronic valve 10 is used to regulate the flow of water to the battery passage (i.e., the main electronic valve channel), and the auxiliary electronic valves (20, 30) are used to regulate the flow of water to the drive motor or the cockpit.

[0049] Figure 4 The main electronic valve 10 includes a controller 12 and an actuator 11. The controller 12 is configured to receive command signals from the vehicle control unit 400 (e.g., specifically including a main valve command signal sent to the main electronic valve and a secondary valve command signal sent to the secondary electronic valve), and parse the command signals to obtain position data or the action name for initializing the secondary electronic valve, etc.; collect or receive feature values ​​(e.g., collect feature values ​​characterizing the rotation state of the main valve motor or receive feature values ​​characterizing the rotation state of the secondary valve motor collected by the information acquisition unit on the secondary electronic valve), and control the on / off of the power supply of the main valve motor or the power supply of the secondary valve motor according to the feature values, thereby controlling the working state of the main valve motor and the secondary valve motor; the actuator 11 is configured to realize the switching of the flow channel where the battery is located and / or the flow ratio adjustment. For example, when the characteristic value is a Hall signal, the main electronic valve is configured to receive main valve command signals and auxiliary valve command signals from the vehicle control unit, and to parse the main valve command signals and auxiliary valve command signals respectively; receive Hall signals from the auxiliary electronic valve, and determine whether the auxiliary valve motor has rotated to the target position based on the Hall signals; when the auxiliary valve motor rotates to the target position, control the auxiliary valve to de-energize; and control the flow channel switching or flow ratio adjustment of the main electronic valve flow channel according to the main valve execution signal. The auxiliary electronic valve is configured to collect motor rotation state parameters, i.e., characteristic values, and feed these characteristic values ​​back to the main electronic valve, and receive control from the main electronic valve to realize the flow channel switching or flow ratio adjustment of the auxiliary valve flow channel. For example, the auxiliary electronic valve feeds back the auxiliary valve Hall signal as a characteristic value to the main electronic valve.

[0050] Figure 5 The controller 12 of the main electronic valve 10 shown includes multiple control ports 121 and an instruction generation unit 122. The instruction generation unit 122 is configured to parse the command signal (e.g., ...). Figure 5 The ECU signals shown include a main valve command signal characterizing the final rotational position of the motor on the main electronic valve and a secondary valve command signal characterizing the final rotational position of the motor on the secondary electronic valve. Position data is obtained, and the main valve motor or the secondary valve motor is energized or de-energized based on the characteristic values ​​and the position data (not shown in the figure). Multiple control ports 121 are configured to: connect to the vehicle control unit 400 to receive command signals from the vehicle control unit ECU (e.g., command signals include main valve command signals and secondary valve command signals); and connect to the secondary electronic valve (e.g., ...). Figure 5The auxiliary electronic valves 20 and 30 shown are connected to receive the characteristic value from the auxiliary electronic valves or to supply power to the auxiliary electronic valves (e.g., Figure 5 (Analysis of ECU signals).

[0051] Figure 6 The diagram shows a portion of the unused interface circuitry of controller 12. The controller 12 of the main electronic valve 10 has six output ports (MOUT0, MOUT1, MOUT2, MOUT3, MOUT4, and MOUT5). One of the auxiliary electronic valves needs to be connected to two of these output ports. Figure 6 The controller 12 can simultaneously drive three auxiliary electronic valves.

[0052] As an optional example, the main electronic valve and the auxiliary electronic valve are connected wirelessly.

[0053] The secondary electronic valve in this application embodiment (e.g., Figure 2 and Figure 3 The first and second auxiliary electronic valves (20 and 30) shown may include: an actuator configured to receive control from the main electronic valve to switch the flow path of the auxiliary valve or to adjust the flow rate proportionally; and a Hall sensor configured to acquire the characteristic value characterizing the rotational state of the motor. For example, the Hall sensor is used to acquire the characteristic value corresponding to the rotational state of the motor in the auxiliary valve flow path, and the characteristic value may include the motor speed or direction of rotation, etc.

[0054] The following is combined Figure 4 Briefly describe the functional modules included in the auxiliary electronic valve.

[0055] like Figure 4 As shown, the secondary electronic valves (20, 30) each include an actuator (22, 32) and a Hall sensor (21, 11). For example, the actuators (22, 32) are configured to regulate the flow path of the secondary valves (e.g., Figure 4 The secondary valve flow path (either the drive motor or the flow path where the cockpit is located) is used for switching and / or flow ratio regulation; Hall sensors (21, 11) are configured to acquire the characteristic values. For example, the Hall sensor acquires characteristic values ​​corresponding to the rotational state of the motor located on the secondary electronic valve actuator 22.

[0056] In this embodiment, both the main electronic valve 10 and the auxiliary electronic valve include actuators that further comprise: a motor, a gear train, and a valve core. The motor drives the gear train to rotate, and the gear train further drives the valve core to rotate, thereby completing the switching of the flow path and the adjustment of the flow ratio. In some examples, a magnetic ring is mounted on the motor shaft, with a gap between the magnetic ring and the Hall sensor. For example, the gap between the magnetic ring and the Hall sensor is recommended to be greater than 0.5 mm and less than 5 mm, because a gap less than 0.5 mm may pose a risk of interference.

[0057] The following is combined Figure 5 The structure of its actuator 11 is explained using the main electronic valve as an example. Since the actuators in the auxiliary electronic valve have the same result as those in the main electronic valve, they will not be described in detail here.

[0058] like Figure 5 As shown, the main electronic valve 10 includes an actuator 11, which further includes a DC motor 113, a gear train 112, and a valve core 114. The DC motor 113 drives the gear train 112 to rotate, and the gear train 112 further drives the valve core 114 to rotate, thereby switching the flow path of the main electronic valve and / or adjusting the flow ratio. In some examples, a magnetic ring (not shown) is also provided on the motor shaft of the DC motor 113, wherein a gap exists between the magnetic ring and the Hall sensor.

[0059] The main electronic valve and the auxiliary electronic valve in the embodiments of this application can be two-way valves, three-way valves, four-way valves, five-way valves or eight-way valves.

[0060] In some examples, the main electronic valve 10 is a four-way electronic valve, and the auxiliary electronic valve is a three-way electronic valve; wherein, when the flow channel is a cooling system flow channel, the four-way electronic valve is at least configured to switch the flow direction of the medium in the cooling system, and the three-way electronic valve is at least configured to control the flow direction and flow rate ratio adjustment of the medium in the cooling system.

[0061] It should be noted that the embodiments of this application do not limit the specific number of auxiliary electronic valves and main electronic valves.

[0062] The following is combined Figure 7 and Figure 8 The technical solutions of the embodiments of this application are illustrated by taking one auxiliary electronic valve and two auxiliary electronic valves as examples respectively.

[0063] like Figure 7 As shown, the main electronic valve 702 is a four-way electronic valve, and the auxiliary electronic valve 701 is a three-way electronic valve. One auxiliary electronic valve is connected to one main electronic valve via a wired connection (i.e.,...). Figure 7 (Wire harness 703). For example, an unused port on the auxiliary electronic valve and main electronic valve controller is connected to the main electronic valve.

[0064] like Figure 8 As shown, the electronic valve system of this application embodiment includes two auxiliary electronic valves (i.e., Figure 8 The system includes a first auxiliary electronic valve 801 and a second auxiliary electronic valve 802, and a main electronic valve 800, wherein the main electronic valve 800 is a four-way electronic valve, which is connected to the vehicle control unit via a first control port 810. Figure 8 (Not shown in the diagram) The second control port 820 is connected to the second auxiliary electronic valve 802 via a wired connection (i.e., wiring harness 821), and the third control port 830 is connected to the first auxiliary electronic valve 801 via a wired connection (i.e., wiring harness 811). For example, the main electronic valve has N control ports, one of which is connected to the ECU port of the vehicle control unit, and the other "N-1" control ports are connected to the auxiliary electronic valves, where N≥2; the circuit board of the main electronic valve includes a controller and a Hall sensor, while the electronic control board of the auxiliary electronic valve may only have a Hall sensor.

[0065] like Figure 8 As shown in the figure, an electronic valve 500 is provided. The electronic valve 500 may include: a controller 510 configured to: receive a main valve command signal and a secondary valve command signal from a vehicle control device, and parse the main valve command signal and the secondary valve command signal; acquire feature values ​​characterizing the rotational state of a first motor, and control the power supply of the first motor to be turned on or off according to the feature values ​​and the parsed main valve command signal, wherein the first motor is located on the main electronic valve; receive feature values ​​characterizing the rotational state of at least one second motor, and control the operating state of at least one second motor according to the feature values, wherein the second motor is located on the secondary electronic valve; provide a power signal to at least one of the secondary electronic valves; and an actuator 520 configured to perform switching of the flow channel of the main electronic valve or flow ratio adjustment.

[0066] The aforementioned command signals are command information sent by the vehicle control unit to adjust the main electronic valve and the auxiliary electronic valve, which is then controlled by the control chip on the main electronic valve (e.g., the control chip includes...). Figure 5 The instruction generation unit 122 and multiple control ports 121 parse the command information for the main electronic valve and the command information for the auxiliary electronic valve, and control the energization or de-energization of the motor on the main electronic valve or the motor on the auxiliary electronic valve according to the received feature values ​​and the parsed data (e.g., the position data used to characterize the final rotation position of the motor).

[0067] It should be noted that, Figure 9 The controller 510 of the electronic valve 500 and Figure 4 The controller 12 is the same, and the actuator 520 is the same. Figure 4The actuator 11 is the same as that of the main electronic valve 10, so the parts that are the same in electronic valve 500 and main electronic valve 10 will not be described here.

[0068] Additionally, the electronic valve 500 or the main electronic valve 10 may also include a power supply circuit (for supplying power to the main electronic valve and the auxiliary electronic valve) and a LIN communication unit (not shown in the figure). For example, both the electronic valve 500 and the main electronic valve 10 are powered by 12V DC. Figure 9 Controller 510 and Figure 4 The controller 12 is integrated on a control chip, which also integrates a motor drive module. The electronic valve 500 or the main electronic valve 10 can also communicate with each other via a LIN communication unit. The control chip of the electronic valve 500 or the main electronic valve 10 determines and controls the motor operation based on the aforementioned characteristic values, and simultaneously acquires Hall signals through a Hall sensor, determining the motor stroke based on the Hall signals and executing the next action. The electronic valve 500 or the main electronic valve 10 also has two expansion interfaces, including a motor control signal interface and a Hall sampling signal interface. The auxiliary electronic valve, through the interface reserved by the main electronic valve, can control the motor operation on the auxiliary electronic valve through the control chip of the main electronic valve (which integrates the aforementioned controller functions). Simultaneously, the auxiliary electronic valve has a Hall sensor, and the control chip of the main electronic valve (i.e., the controller in the above scheme) acquires the Hall signal from the auxiliary electronic valve to further control the motor operation on the auxiliary electronic valve (e.g., controlling whether to continue energizing or de-energizing the auxiliary electronic valve).
