Description

Technical Field

[0001] This invention relates to the field of automotive parts, and in particular to a water valve, a method for adjusting the deflection angle of the water valve, and a vehicle. Background Technology

[0002] like Figure 1 As shown, the vehicle includes a water valve, a controller, a motor, a data collector, and a transmission assembly. The water valve can be one or more types, from a three-way valve to a ten-way valve. The water valve includes a pointer, a protective cover, a conductive ring, a resistor, and a central shaft. The positioning end of the pointer is rotatably mounted on the central shaft, and the indicating end of the pointer contacts the resistor and the conductive plate in sequence.

[0003] In actual operation, the data acquisition unit will collect the corresponding electrical signal (voltage information) based on the resistance value of the resistor. The controller will then use the electrical signal uploaded by the data acquisition unit to rotate the pointer end through the motor, transmission components and central shaft in sequence, so that the pointer end points to the appropriate position of the resistor, thereby allowing the water valve to form the corresponding water flow path according to the actual needs of the vehicle.

[0004] Regarding the aforementioned existing technical solutions, the inventors discovered that because the indicating end of the pointer frequently needs to slide on the resistor, after prolonged use, the position of the resistor in the water valve corresponding to the water flow path (i.e., the contact point between the resistor and the indicating end of the pointer) is prone to wear. This causes the water valve (the indicating end of the pointer) to be unable to adjust the deflection angle of the pointer according to the actual needs of the vehicle, thus making it difficult for the water valve to form the corresponding water flow path according to the actual needs of the vehicle. Therefore, it is necessary to improve this. Summary of the Invention

DETAILED DESCRIPTION

[0023] In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0024] As shown in Figure 2 The existing structure related to the water valve 5 in the vehicle includes a controller 1, a motor 2, a transmission assembly 3, the water valve 5 and a collector 6. The controller 1, the motor 2, the transmission assembly 3, the water valve 5 and the collector 6 are all arranged in a box cover 4. The transmission assembly 3 can be a gear transmission member. The collector 6 is used to collect an electric signal (voltage information) generated by a resistor 52 on the water valve 5. The controller 1 determines the deflection angle of the water valve 5 according to the electric signal (voltage information) collected by the collector 6.

[0025] In actual work, the controller 1 calculates the deflection angle required by the water valve 5 according to the actual water flow path requirement of the vehicle (for example, the first channel and the third channel need to be kept in communication). Then, the controller 1 makes the central shaft 55 (gear shaft) in the water valve 5 deflect by the above-mentioned deflection angle through the motor 2 and the transmission assembly 3 in turn according to the deflection angle, so that the water valve 5 can be kept in a smooth state according to the actual requirement, and the vehicle can be driven out of the dangerous road surface and into the repair factory.

[0026] In the above technical solution, when the central shaft 55 rotates, the pointer 54 will also produce a corresponding deflection angle, that is, the indicating end 542 of the pointer 54 in the water valve 5 needs to slide on the resistor 52. The inventor finds that after the water valve 5 is used for a long time, the position corresponding to the water flow path of the resistor 52 in the water valve 5 (that is, the contact position of the indicating end 542 of the pointer 54 on the resistor 52) is prone to wear, which causes the electric signal (voltage information) collected by the collector 6 at the worn position of the water valve 5 to be inaccurate, thereby causing the deflection angle of the water valve 5 to be prone to error, and the central shaft 55 of the water valve 5 cannot be adjusted to the preset deflection angle according to the actual requirement. Therefore, it is necessary to improve.

[0027] The prior art has a multi-section regulating potentiometer, which comprises a shell, a rotating shaft, a carbon film resistor sheet and a brush. The rotating shaft is arranged at the center of the shell, the carbon film resistor sheet is in a ring structure with an opening, the brush is connected to the rotating shaft and corresponds to the carbon film resistor sheet, the carbon film resistor sheet is provided with two wire terminals at two ends, the rotating shaft is provided with wire terminals communicated with the brush, and the rotating shaft is further provided with a multi-section regulating device. The multi-section regulating device is arranged to regulate the rotation of the brush according to different rotation speeds, and the brush is not prone to misoperation under the action of the regulating device after regulation, thereby effectively ensuring the stability of the potentiometer regulation.

[0028] The above multi-section regulating potentiometer only mechanically ensures resistance adhesion, and still needs full-range judgment for automatic control and self-learning after durability, and it is not easy to ensure resistance self-learning identification of important points, and therefore, improvement is necessary.

[0029] In view of the above technical problems, the embodiments of the present application provide a water valve, a deflection angle adjusting method of the water valve and a vehicle, so as to solve the problem that the water valve 5 is difficult to form a corresponding water flow path according to the actual demand of the vehicle after a long time of use.

[0030] As shown in Figure 2 and Figure 3 , the present application provides a water valve 5, which comprises a protective cover 51 and a center shaft 55, the protective cover 51 is provided with a plurality of branch pipes; a resistor 52 arranged in the protective cover 51, the resistor 52 comprises a plurality of segmented resistors 521 arranged at intervals and having different resistance values, and a conductive sheet 522 located between two adjacent segmented resistors 521 and corresponding to the position of the passage opening of the branch pipe; a pointer 54, the pointer 54 comprises a positioning end 541 and an indicating end 542, the positioning end 541 of the pointer 54 is rotatably arranged on the center shaft 55, and the indicating end 542 of the pointer 54 is in contact with the segmented resistor 521 or the conductive sheet 522.

[0031] In actual work, when the resistor 52 on the water valve 5 is locally worn due to long-term use, the resistance value formed by the local wear site and the indicating end 542 of the pointer 54 will not be accurate in actual measurement, resulting in that the electric signal collected by the collector 6 at the above local wear site is also not accurate, so that the electric signal (voltage information) collected by the collector 6 cannot accurately reflect the position of the indicating end 542 on the resistor 52.

[0032] When the structure of the water valve 5 is adopted, the position of the conductive sheet 522 corresponds to the position of the branch pipe of the water valve 5 (one-to-one correspondence), so when the part of the conductive sheet 522 that is always in contact with the indicating end 542 of the pointer 54 is worn (the conductive sheet 522 at this time is referred to as a faulty conductive sheet 522), the present application only needs to slide the indicating end 542 of the pointer 54 to the part of the faulty conductive sheet 522 that is not worn.

[0033] At this time, the electrical signal collected by the collector on the faulty conductive sheet 522 is still the preset electrical signal (voltage information), so when the collector collects the electrical signal (voltage information) on the resistor 52, it is basically not affected by the above-mentioned locally worn part, and when the controller 1 controls the deflection angle of the water valve 5, it only needs to control the deflection angle of the center shaft 55 according to the electrical signal uploaded by the collector, so the controller 1 of the present application is not affected by the locally worn part when adjusting the deflection angle of the center shaft 55, and the water valve 5 can more accurately meet the actual use requirements of the vehicle and keep its own water flow passage in the corresponding unobstructed state.

[0034] In actual work, in addition to the above-mentioned protective cover 51, center shaft 55, pointer 54 and resistor 52, the water valve 5 also includes a conductive ring 53 and a collector 6, the conductive ring 53 is located between the resistor 52 and the inner wall of the protective cover 51, the conductive ring 53 and the resistor 52 are in overall arc-shaped ring structure, and the protective cover 51, the conductive ring 53, the resistor 52 and the center shaft 55 are coaxially arranged, so that the water valve 5 not only has a more compact and beautiful structure, but also makes it easier for the controller 1 to adjust the deflection angles of the center shaft 55 and the pointer 54.

[0035] In actual work, the protective cover 51 can protect the conductive ring 53, the resistor 52, the center shaft 55 and the pointer 54 to a certain extent; the indicating end 542 of the pointer 54 can be used to extract the resistance on the resistor 52 when it is in contact with the resistor 52 and the conductive ring 53; the resistor 52 is divided into a plurality of segmented resistors 521 with different resistance values, and a conductive sheet 522 is arranged between adjacent two segmented resistors 521, so that when the resistor 52 is worn at a position corresponding to the water flow passage, the indicating end 542 of the pointer 54 is manually or automatically controlled by the preset control software to slide on the conductive sheet 522 until the indicating end 542 of the pointer 54 is placed on the part of the conductive sheet 522 that is not worn, so that the present application can more accurately adjust the center shaft 55 to the preset deflection angle, and the water valve 5 can meet the actual use requirements of the vehicle and keep its own water flow passage in the corresponding unobstructed state.

[0036] The resistor 52 of the present application can be a carbon film resistor. In this way, the present application also realizes the arrangement of the resistor 52, under the action of the above-mentioned carbon film resistor, the sensitivity of the electrical signal collected by the collector is higher, which can make the present application more accurately adjust the indicating end 542 and the center shaft 55 to the preset deflection angle, so that the water valve 5 can be in the corresponding unobstructed state according to the actual use demand of the vehicle.

[0037] The resistance values of the plurality of segmented resistors 521 gradually increase from the starting point of the resistor 52 to the end point of the resistor 52. In this way, the present application can generate a variable (gradually increasing) electrical signal (voltage information) on the resistor 52 when the indicating end 542 of the pointer 54 slides on the resistor 52, so that the controller 1 can obtain more accurate electrical signals, thereby more accurately controlling the deflection angle of the water valve 5.

[0038] The resistance values of the segmented resistors 521 are linearly arranged. In actual work, as shown in the figure, Figure 4 The resistance value of the resistor 52 is nonlinear, specifically: from the starting point A1 to P1, from P1 to P2, from P2 to Pn, and from Pn to the end point A2 of the resistor.

[0039] When the indicating end 542 of the pointer 54 is placed at different positions of the segmented resistors 521 (non-conductive pieces 522), different resistance values will be displayed on the resistor 52, so that the collector will collect different electrical signals (voltage information) according to the different resistance values of the resistor 52. At this time, the controller 1 can accurately determine the position of the indicating end 542 of the pointer 54 on the resistor 52 according to the above-mentioned electrical signals, so that the controller 1 can more accurately adjust the deflection angle of the center shaft 55 through the motor 2 and the transmission assembly 3 and other components, and then the water valve 5 can be in the corresponding unobstructed state according to the actual use demand of the vehicle.

[0040] Among the plurality of segmented resistors 521, a resistance difference is provided between the output end of the previous segmented resistor 521 and the input end of the next segmented resistor 521, and the resistance difference is 0.5-1kΩ. In this way, the resistance value of the input end of the next segmented resistor 521 is quite different from the resistance value of the output end of the previous segmented resistor 521, thereby avoiding the overlapping of the deflection angle caused by the wear of the conductive piece 522, so that the present application can obtain more accurate electrical signals, and then obtain more accurate deflection angles.

[0041] The included angle between the end of the conductive sheet 522 at both ends and the center line of the center shaft 55 is 2-8°. In actual work, the position of the conductive sheet 522 on the resistor 52 can also be called an important conductive position, and the included angle is much larger than the angle precision that can be controlled and distinguished by the controller 1. Meanwhile, the included angle between the conductive sheet 522 and the center of the center shaft 55 can be determined by the angle precision error that needs to be controlled in design, so that the application can obtain more accurate electric signals and more accurate deflection angles.

[0042] Preferably, the included angle between the end of the conductive sheet 522 at both ends and the center line of the center shaft 55 is 6°. In this way, the resistor 52 of the application has lower manufacturing difficulty, and the deflection angle of the water valve 5 is easier to be controlled.

[0043] In actual work, the position of the conductive sheet 522 on the resistor 52 can also be called an important conductive position, which can allow the application to correct the circuit and realize the self-learning function when the resistance of the resistor 52 is unchanged. Meanwhile, the included angle between the important conductive position and the center of the center shaft 55 is the design allowable error. If the error is too small, the application is still easily affected by the local wear position of the conductive sheet 522 when the controller 1 adjusts the deflection angle of the center shaft 55. If the error is too large, the application is easy to cause the water valve 5 to leak when the controller 1 adjusts the deflection angle of the center shaft 55. Finally, since the resistance difference between the input end and the output end in the important conductive position can be ignored, the change caused by the local wear on the resistor 52 is small.

[0044] In actual work, the blank position between the upper and lower edges X1 and X2 is the position of the conductive sheet 522 on the resistor 52 (as shown in Figure 3 、 Figure 4 The included angle between the end of the conductive sheet 522 at both ends and the center line of the center shaft 55 is much larger than the resolution of the controller 1, and the design needs to control the angle error.

[0045] In actual work, the resistor 52 is provided with four segmented resistors 521, and the collector 6 obtains the corresponding electric signals (voltage information) by measuring the resistance value formed from the starting end (A1) of the resistor 52 to the contact position of the conductive sheet 522 and the indicating end 542 of the pointer 54. During the service life from the starting end (starting point A1) of the resistor 52 to the terminal end (terminal point A2) of the resistor 52, the resistance value changes due to local wear, and the resistance value satisfies: (A1 to P1) < (P1 to P2) < (P2 to Pn) < (Pn to A2).

[0046] In actual work, when the resistance of the resistor 52 needs to be measured to determine the deflection angle of the water valve 5 (the central shaft 55), the pointer 54 slides from the starting end (the starting point A1) of the resistor 52 to the end (the ending point A2) of the resistor 52, passes through the important conductive point P1, and enters the region with equal resistance formed by X1 and X2. X1 is the input end of the conductive sheet 522, and X2 is the output end of the conductive sheet 522.

[0047] In the embodiment, the control error region of the important conductive point is ±3°, and ∠A1S6A2 is 240°. Thus, the pointer 54 forms a 6 / 240=1 / 40 region from X1 to X2. In actual work, the time of the pointer 54 from A1 (the starting point of the resistor 52) to A2 (the ending point of the resistor 52) on the driving gear shaft is 6S. Thus, the time required from X1 to X2 is 0.15S (much greater than the signal reaction time 10ms). Thus, the resistance between A1 and A2 collected on the collector 7 is approximately as shown in the following table. Figure 4

[0048] The protective cover 51 is made of transparent material (i.e., the protective cover 51 is transparent), and the protective cover 51 is provided with a mark 56 corresponding to the position of the passage of the branch pipeline. Thus, the application realizes a visual design. When the transmission gear, the collector and other components are damaged or fail, the application only needs to remove the protective cover 51 and directly rotate the central shaft 55 to the specified deflection angle by using a tool, so as to ensure the safe return of the vehicle.

[0049] The protective cover 51 can be assembled on the box cover 4 (preferably transparent) by threading or screwing. Thus, the working state of the pointer 54, the mark and the conductive sheet 522 can be easily observed by the worker, so as to facilitate the worker to maintain the water valve 5. The mark 56 can guide the worker to rotate the rotating shaft (manually) to the appropriate angle.

[0050] The central shaft 55 is a gear shaft, and the central shaft 55 is provided with a rotating member coaxial with the central shaft 55 and capable of driving the central shaft 55 to rotate. In actual work, the rotating member can be a spline, so that the worker can manually twist the central shaft 55 to make the indicating end 542 of the pointer 54 point to the appropriate position of the resistor 52, so as to make the application more convenient to use.

[0051] In actual work, when the collector 6 detects that the indicating end 542 of the pointer 54 enters the important conductive point (such as Figure 4 ​When the pointer is in the region X1 to X2, the resistance of resistor 52 remains unchanged during this process, and pointer 54 will still be linked with the gear shaft. Therefore, water valve 5 will also enter the position of marker 56. After a long period of wear, the system can also, based on the measured resistance and the electrical signal (voltage information) recorded on the collector corresponding to this resistance, manually or through preset control software, slide the indicating end 542 of pointer 54 on the conductive plate 522 until the indicating end 542 of pointer 54 is placed on the conductive plate 522 in a position where it is not worn. In this way, the present invention realizes the automatic correction and adjustment of the position of pointer 54. At the same time, since there is no resistance in X1 to X2, the resistance loss is small and the correction effect is high.

[0052] In actual operation, when the gear meshing is damaged due to prolonged operation or malfunction inside the gear shaft, the vehicle cannot move because the water valve 5 cannot move to the position of the preset marker 56. At this time, the driver can open the cover 4 and use a simple automotive tool (such as a wrench or socket) to rotate the rotating part (spline) on the gear shaft to rotate the indicating end 542 of the pointer 54 to the position of the preset marker 56, so that the vehicle can drive out of the dangerous road and enter the repair shop.

[0053] Secondly, the present invention provides a method for adjusting the deflection angle of a water valve 5, comprising:

[0054] S1. Determine whether the water valve 5 is faulty when adjusting the angle, and obtain the determination result;

[0055] S2. If the judgment result is negative, then the water valve 5 shall continue to adjust the deflection angle according to the preset angle adjustment method.

[0056] S3. If the judgment result is yes, then obtain the position of the conductive sheet 522 on the current resistor 52 that is in contact with the indicating end 542 of the pointer 54, and use preset control software to make the indicating end 542 of the pointer 54 slide on the conductive sheet 522 until the indicating end 542 of the pointer 54 is placed on the conductive sheet 522 at a position where it is not worn.

[0057] In actual operation, when water valve 5 suffers from resistance wear, causing the branch pipe to fail to maintain connection with the main pipe as designed, meaning water valve 5 cannot effectively form the corresponding water flow path according to the vehicle's actual needs, existing technologies typically require replacing water valve 5 (or performing on-site maintenance on water valve 5) to ensure the vehicle's normal operating performance at water valve 5. Furthermore, when the vehicle is traveling on the road, especially in dangerous road conditions, the aforementioned existing technical solutions are difficult to implement and pose certain safety hazards.

[0058] In view of the problem that the branch pipeline cannot be kept in communication with the main pipeline according to the design requirement due to the resistance wear of the water valve 5, the present application only needs to deflect the indicating end 542 of the pointer 54 according to the preset angle through the controller 1, so that the water valve 5 can form the corresponding water flow passage according to the actual requirement of the vehicle, and the reason is as follows:

[0059] Since the segmented resistance 521 of the resistor 52 is not arranged at the position corresponding to the passage opening of the branch pipeline, the segmented resistance 521 is less likely to be worn. Meanwhile, when the conductive sheet 522 is worn, since the indicating end 542 of the pointer 54 can slide to the position of the conductive sheet 522 which is not worn, the collector can collect the same electric signal regardless of whether the conductive sheet 522 is worn after a long time, so that the present application only needs to deflect the indicating end 542 of the pointer 54 according to the preset angle through the controller 1.

[0060] In actual work, since the water valve 5 has the above technical effects, the deflection angle adjusting method of the water valve 5 containing the water valve 5 should also have the same technical effects. In actual work, the specific limitation of the deflection angle adjusting method of the water valve 5 of the present application can be referred to the limitation of the water valve 5 in the above, which will not be repeated here.

[0061] In the third aspect, the present application provides a vehicle, which comprises a controller 1, a motor 2 and a transmission assembly 3, and a water valve 5, wherein the water valve 5 is provided with an information collector for collecting the electric signal on the resistor 52, the information collector is used for sending the electric signal to the controller 1, and the controller 1 is used for controlling the deflection angle of the pointer 54 through the motor 2, the transmission assembly 3 and the center shaft 55 in sequence according to the electric signal.

[0062] In actual work, since the water valve 5 has the above technical effects, the vehicle containing the water valve 5 should also have the same technical effects. In actual work, the specific limitation of the vehicle of the present application can be referred to the limitation of the water valve 5 in the above, which will not be repeated here.
