Description

Technical Field

[0001] The present application relates to the technical field of automobile parts, and in particular to an expansion kettle and a method for controlling the water level of the expansion kettle. Background Art

[0002] Auto parts are the various units that make up the entire car and are products that serve the car. With the improvement of people's living standards, people's consumption of cars is increasing, which makes the market for auto parts become larger and larger.

[0003] In the related art, there are many types of automotive accessories. The expansion kettle is an automotive accessory in the automotive cooling system. The expansion kettle is installed slightly above the radiator and includes a kettle body. The kettle body is provided with an inlet for coolant to flow into the kettle body, a water inlet for the coolant in the kettle body to flow back into the automotive cooling system, an overflow port for excess coolant or gas in the kettle body to overflow, and a water inlet for adding water. When the pressure in the cooling system is too high or the coolant temperature rises, excess gas and coolant will flow out of the overflow port. When the pressure in the cooling system is too low or the coolant temperature drops, the coolant in the expansion kettle will be replenished into the cooling system, thereby allowing the expansion kettle to maintain pressure and replenish the cooling system. A liquid level sensing device is installed on the kettle body for detecting and outputting feedback on the coolant at the water inlet in the kettle body. The detection and feedback output by the liquid level sensing device facilitates the operator to understand whether the coolant level in the kettle body is within the normal water level range.

[0004] Regarding the above-mentioned related technologies, the following defects were found: during the use of the cooling system, the coolant in the expansion kettle will be consumed as the number of uses and the duration of use increase. When the cooling system is used frequently, the coolant in the expansion kettle will easily drop below the normal water level range, requiring the operator to frequently add coolant in the expansion kettle. There is still room for improvement. Summary of the Invention

[0005] In order to reduce the frequency of an operator adding coolant to an expansion kettle, the present application provides an expansion kettle and a method for controlling the water level of the expansion kettle.

[0006] In a first aspect, the present application provides an expansion kettle, which adopts the following technical solution:

[0007] An expansion kettle, comprising a kettle body and a cover plate, the kettle body being provided with a liquid discharge cavity for placing coolant, the cover plate being used to cover the liquid discharge cavity, a water inlet being provided on the circumferential side wall of the cover plate, a water outlet being provided on the side of the circumferential side wall of the kettle body close to the ground, the water inlet and the water outlet being communicated with the liquid discharge cavity, a liquid level sensing device being provided on the cover plate for detecting the liquid level at the water outlet, a liquid pusher plate being slidably connected to the kettle body for pushing the coolant toward the side close to the water outlet, a pushing member being provided on the kettle body for driving the liquid pusher plate to move, the liquid pusher plate being located in the liquid discharge cavity, and the pushing member being provided on the inner side wall of the liquid discharge cavity away from the water outlet.

[0008] By adopting the above technical solution, a liquid pushing plate is slidably connected to the kettle body. When the coolant in the kettle body drops below the normal water level range, the liquid pushing plate is driven by the pushing member to move toward the water outlet, thereby reducing the volume of the coolant placed in the kettle body and raising the coolant level in the kettle body. As a result, the coolant in the kettle body can continue to meet the usage needs, thereby reducing the operator's frequency of adding coolant to the expansion kettle.

[0009] Optionally, a pulling assembly is provided on a side of the liquid pushing plate away from the pushing member, and the pulling assembly is used to control the liquid pushing plate to move toward a side close to the water outlet;

[0010] The pulling assembly includes a tensioned member arranged on the liquid pushing plate, an inflation control member for controlling the movement of the liquid pushing plate, and a connecting member arranged on the inflation control member, the connecting member being used to rotatably connect the tensioned member, a limiting plate being provided on the inner side wall of the liquid discharge cavity near the water outlet, and the limiting plate being used to limit the movement of the inflation control member along the length direction of the limiting plate.

[0011] By adopting the above technical solution, when the inflation control part moves as the liquid level of the coolant in the kettle body rises or falls, the inflation control part is limited by the limit plate to move along the length direction of the limit plate, thereby assisting the push plate to move slightly, thereby reducing the force required by the pushing part and facilitating the pushing part to control the movement of the push plate.

[0012] Optionally, the connecting member includes a connecting column arranged on the inflation control member, a mounting block for being installed with the connecting column, and a rotating block for being rotatably connected with the tension member, the rotating block is located on the side of the mounting block close to the tension member, there are two rotating blocks in total, and the two rotating blocks are symmetrically arranged about the tension member, a rotating groove is provided on the rotating block for the tension member to be placed and rotated, and a guide surface for the tension member to move into the rotating groove is provided on the side of the rotating block close to the tension member.

[0013] By adopting the above technical solution, a rotating groove is provided on the rotating block, and the rotating block is symmetrically arranged about the tension member, thereby facilitating the placement and rotation of the tension member, and the guide surface facilitates the operator to place the tension member in the rotating groove.

[0014] In a second aspect, the present application provides a method for controlling the water level of an expansion kettle, which adopts the following technical solution:

[0015] A method for controlling the water level of an expansion kettle, comprising:

[0016] Get the liquid level detection value;

[0017] Determine whether the liquid level detection value is within the preset liquid level reference range;

[0018] If yes, continue to obtain the liquid level detection value;

[0019] If not, the liquid level adjustment value corresponding to the liquid level detection value and the liquid level reference interval is analyzed and obtained according to the correspondence between the liquid level detection value, the liquid level reference interval and the preset liquid level adjustment value, and the liquid level adjustment value is sent to the pusher.

[0020] By adopting the above technical solution, the liquid level detection value is obtained, and it is judged whether the liquid level detection value is within the preset liquid level reference interval. When it is within the liquid level reference interval, the liquid level detection value is continued to be obtained. When it is not within the liquid level reference interval, the liquid level adjustment value is obtained by analyzing the liquid level detection value and the liquid level reference interval, and the liquid level adjustment value is sent to the pushing member, thereby controlling the pushing member to drive the liquid pushing plate to move, changing the volume of the coolant placed in the kettle body, and raising the coolant level in the kettle body, so that the coolant in the kettle body can continue to meet the use requirements, thereby reducing the operator's frequency of adding coolant to the expansion kettle, and making it less likely for the operator to use too much coolant in the expansion kettle, which will affect the expansion kettle.

[0021] Optionally, the method further includes the following steps after obtaining the liquid level detection value and before determining whether the liquid level detection value is within a preset liquid level reference interval:

[0026] By adopting the above technical solution, a preliminary adjustment value is obtained by analyzing the liquid level deviation value and the liquid level reference interval, and then the vehicle inclination angle detection value is obtained. The vehicle inclination liquid level impact value is obtained by analyzing the vehicle inclination angle detection value, and the final adjustment value is obtained by analyzing the preliminary adjustment value and the vehicle inclination liquid level impact value. The final adjustment value is used as the liquid level adjustment value, so that the obtained liquid level adjustment value is not easily affected by the vehicle inclination, thereby improving the accuracy of the obtained liquid level adjustment value.

[0027] Optionally, according to the correspondence between the liquid level deviation value, the liquid level reference interval, and the preset preliminary adjustment value, analyzing and obtaining the preliminary adjustment value corresponding to the liquid level deviation value and the liquid level reference interval includes:

[0028] Determine whether the liquid level detection value is greater than the maximum value corresponding to the liquid level reference interval;

[0029] If yes, then, according to the maximum value corresponding to the liquid level detection value and the liquid level reference interval, analyze and calculate the difference between the liquid level detection value and the maximum value corresponding to the liquid level reference interval and use the difference as the reduction adjustment value, and use the reduction adjustment value as the liquid level adjustment value;

[0030] If not, the difference between the liquid level detection value and the minimum value corresponding to the liquid level reference interval is analyzed and calculated based on the liquid level detection value and the minimum value corresponding to the liquid level reference interval and used as the increase adjustment value.

[0031] By adopting the above technical solution, it is judged whether the liquid level detection value is greater than the maximum value corresponding to the liquid level reference interval. When it is greater than, the difference between the liquid level detection value and the maximum value corresponding to the liquid level reference interval is analyzed and calculated, and the difference is used as a reduction adjustment value, and the reduction adjustment value is used as the liquid level adjustment value, so as to control the push member to drive the push plate to move away from the water outlet, increase the volume of coolant placed in the kettle body, and lower the coolant level in the kettle body. When it is not greater than, the difference between the liquid level detection value and the minimum value corresponding to the liquid level reference interval is analyzed and calculated, and the difference is used as an increase adjustment value, and the increase adjustment value is used as the liquid level adjustment value, so as to control the push member to drive the push plate to move toward the water outlet, reduce the volume of coolant placed in the kettle body, and increase the coolant level in the kettle body.

[0035] Determine whether the actual liquid level value of the auxiliary detection is consistent with the preset auxiliary detection reference liquid level value;

[0036] If yes, continue to output the liquid level adjustment value;

[0037] If not, the difference between the actual auxiliary detection liquid level value and the auxiliary detection reference liquid level value is analyzed and calculated based on the auxiliary detection actual liquid level value and the auxiliary detection reference liquid level value, and is used as the auxiliary detection deviation liquid level value;

[0038] According to the correspondence between the auxiliary detection deviation liquid level value and the preset auxiliary detection adjustment liquid level value, the auxiliary detection adjustment liquid level value corresponding to the auxiliary detection deviation liquid level value is analyzed and obtained, and the auxiliary detection adjustment liquid level value is added to the liquid level adjustment value to form a new liquid level adjustment value.

[0039] By adopting the above technical solution, the position point of the inflation control component is obtained and used as the liquid level auxiliary detection position point, and the actual liquid level value of the auxiliary detection is obtained through analysis of the liquid level auxiliary detection position point, and then a judgment is made as to whether the actual liquid level value of the auxiliary detection is consistent with the preset auxiliary detection reference liquid level value. When consistent, the liquid level adjustment value is continued to be output. When inconsistent, the difference between the actual liquid level value of the auxiliary detection and the auxiliary detection reference liquid level value is analyzed and calculated, and the difference is used as the auxiliary detection deviation liquid level value. The auxiliary detection adjustment liquid level value is obtained through auxiliary detection deviation liquid level value analysis, and the auxiliary detection adjustment liquid level value is added to the liquid level adjustment value to form a new liquid level adjustment value, so that the coolant level in the kettle body is further detected through the position of the inflation control component, and the liquid level adjustment value is adjusted, thereby further improving the accuracy of the obtained liquid level adjustment value.

[0040] Optionally, according to the correspondence between the auxiliary liquid level detection position point and the preset auxiliary detection actual liquid level value, analyzing and obtaining the auxiliary detection actual liquid level value corresponding to the auxiliary liquid level detection position point includes:

[0042] Analyze and obtain the vehicle tilt auxiliary detection influence value corresponding to the vehicle tilt angle value according to the corresponding relationship between the vehicle tilt angle value and the preset vehicle tilt auxiliary detection influence value;

[0043] According to the correspondence between the initial liquid level value of the auxiliary detection, the vehicle tilt auxiliary detection impact value and the preset final liquid level value of the auxiliary detection, the final liquid level value of the auxiliary detection corresponding to the initial liquid level value of the auxiliary detection and the vehicle tilt auxiliary detection impact value is analyzed and obtained, and the final liquid level value of the auxiliary detection is used as the actual liquid level value of the auxiliary detection.

[0044] By adopting the above technical solution, the initial liquid level value of the auxiliary detection is obtained by analyzing the liquid level auxiliary detection position point, the vehicle tilt auxiliary detection influence value is obtained by analyzing the vehicle tilt angle value, and then the final liquid level value of the auxiliary detection is obtained by analyzing the initial liquid level value of the auxiliary detection and the vehicle tilt auxiliary detection influence value, and the final liquid level value of the auxiliary detection is used as the actual liquid level value of the auxiliary detection, so that the obtained actual liquid level value of the auxiliary detection is not easily affected by the vehicle tilt, thereby improving the accuracy of the obtained actual liquid level value of the auxiliary detection.

[0045] Optionally, according to the correspondence between the auxiliary detection deviation liquid level value and the preset auxiliary detection adjustment liquid level value, analyzing and obtaining the auxiliary detection adjustment liquid level value corresponding to the auxiliary detection deviation liquid level value includes:

[0046] According to the corresponding relationship between the auxiliary detection deviation liquid level value and the preset adjustment liquid level initial value, the adjustment liquid level initial value corresponding to the auxiliary detection deviation liquid level value is analyzed and obtained;

[0047] Determine whether the auxiliary detection deviation liquid level value is greater than a preset deviation liquid level reference value;

[0048] If yes, then according to the auxiliary detection deviation liquid level value and the deviation liquid level reference value, analyze and calculate the difference between the auxiliary detection deviation liquid level value and the deviation liquid level reference value and use it as the deviation liquid level deviation value;

[0049] According to the correspondence between the deviation liquid level deviation value and the preset adjustment liquid level deviation adjustment value, analyzing and obtaining the adjustment liquid level deviation adjustment value corresponding to the deviation liquid level deviation value;

[0050] According to the correspondence between the adjustment value of the adjustment liquid level deviation, the initial value of the adjustment liquid level and the preset final value of the adjustment liquid level, the final value of the adjustment liquid level corresponding to the adjustment value of the adjustment liquid level deviation and the initial value of the adjustment liquid level is analyzed and obtained, and the final value of the adjustment liquid level is used as the auxiliary detection adjustment liquid level value;

[0051] If not, the initial value of the adjusted liquid level is directly used as the auxiliary detection adjusted liquid level value.

[0052] By adopting the above technical solution, the initial value of the adjustment liquid level is obtained by analyzing the auxiliary detection deviation liquid level value, and then it is judged whether the auxiliary detection deviation liquid level value is greater than the preset deviation liquid level reference value. When it is greater, the difference between the auxiliary detection deviation liquid level value and the deviation liquid level reference value is analyzed and calculated, and the difference is used as the deviation liquid level deviation value. The adjustment liquid level deviation adjustment value is obtained by analyzing the deviation liquid level deviation value, and the final value of the adjustment liquid level is obtained by analyzing the adjustment liquid level deviation adjustment value and the initial value of the adjustment liquid level, and the final value of the adjustment liquid level is used as the auxiliary detection adjustment liquid level value. When it is not greater than, the initial value of the adjustment liquid level is directly used as the auxiliary detection adjustment liquid level value, thereby improving the accuracy of the obtained auxiliary detection adjustment liquid level value.

[0053] Optionally, according to the correspondence between the deviation liquid level deviation value and the preset adjustment liquid level deviation adjustment value, analyzing and obtaining the adjustment liquid level deviation adjustment value corresponding to the deviation liquid level deviation value includes:

[0055] Determine whether the deviation value of the deviation liquid level is greater than a preset deviation liquid level deviation reference value;

[0056] If yes, then output the jamming alarm information to the terminal held by the operator;

[0057] If not, the preliminary adjustment value of the adjusted liquid level deviation is used as the adjusted liquid level deviation adjustment value.

[0058] By adopting the above technical solution, the preliminary adjustment value of the adjustment liquid level deviation is obtained through the deviation liquid level deviation value analysis, and it is judged whether the deviation liquid level deviation value is greater than the preset deviation liquid level deviation reference value. When it is greater, a jam alarm message is output to the terminal held by the operator. When it is not greater, the preliminary adjustment value of the adjustment liquid level deviation is used as the adjustment liquid level deviation adjustment value, so as to judge whether a jam occurs between the inflation control component and the limit plate. When a jam occurs, a jam alarm message is output to the terminal held by the operator, so as to facilitate the operator to understand. When no jam occurs, it means that the obtained preliminary adjustment value of the adjustment liquid level deviation is not affected, so the preliminary adjustment value of the adjustment liquid level deviation is used as the adjustment liquid level deviation adjustment value.

[0059] In summary, this application includes at least one of the following beneficial technical effects:

[0060] 1. A push plate is slidably connected to the kettle body. When the coolant in the kettle drops below the normal water level range, the push plate is driven by a pusher to move closer to the water outlet, reducing the volume of coolant placed in the kettle and raising the coolant level in the kettle. This allows the coolant in the kettle to continue to meet usage needs, thereby reducing the operator's frequency of adding coolant to the expansion kettle.

[0061] 2. When the inflation control member moves as the coolant level in the kettle rises or falls, the inflation control member is limited by the limit plate to move along the length direction of the limit plate, thereby slightly assisting the push plate to move, thereby reducing the force required by the push member and facilitating the push member to control the movement of the push plate;

DETAILED DESCRIPTION

[0074] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-10 It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0075] Reference Figure 1 and Figure 2 The embodiment of the present application discloses an expansion kettle, which includes a kettle body 1 and a cover plate 2. The kettle body 1 is provided with a drain chamber 3 for placing coolant, and the cover plate 2 is used to cover the drain chamber 3, so that the coolant in the drain chamber 3 is not easily spilled out by the cover plate 2. A water inlet 4 for allowing coolant to enter the drain chamber 3 is integrally provided on the circumferential side wall of the cover plate 2, and the water inlet 4 is used to connect the drain chamber 3 with the outside world at the cover plate 2. A water outlet 5 for allowing coolant to flow out of the drain chamber 3 is integrally provided on the side of the circumferential side wall of the kettle body 1 close to the ground, and the water outlet 5 is used to connect the drain chamber 3 with the outside world on the side of the kettle body 1 close to the ground. A liquid level sensing device 6 for detecting the liquid level at the water outlet 5 is installed on the cover plate 2. The liquid level at the water outlet 5 is detected by the liquid level sensing device 6, so that the operator can understand the liquid level at the water outlet 5 conveniently. In this embodiment, there are two water inlets 4 , the diameter of the water inlet 4 is smaller than the diameter of the water outlet 5 , and the water inlet 4 is located on the circumferential side wall of the cover plate 2 and is adjacent to the water outlet 5 on the circumferential side wall of the kettle body 1 .

[0076] Reference Figure 1 and Figure 2 , a push plate 7 is slidably connected to the kettle body 1, and the push plate 7 is located in the liquid discharge chamber 3. The height direction of the push plate 7 is consistent with the height direction of the kettle body 1. The push plate 7 is used to push the coolant to the side close to the water outlet 5. The push plate 7 fits tightly with the cavity wall of the liquid discharge chamber 3, and a sealing strip is installed between the push plate 7 and the cavity wall of the liquid discharge chamber 3, so that the coolant is not easy to overflow from the gap between the push plate 7 and the cavity wall of the liquid discharge chamber 3. A pusher 8 for driving the push plate 7 to move is installed on the kettle body 1. The pusher 8 is located on the inner side wall of the liquid discharge chamber 3 away from the water outlet 5. The pusher 8 drives the push plate 7 to move, thereby changing the volume of the coolant that can be placed in the liquid discharge chamber 3, and then adjusting the liquid level of the coolant in the liquid discharge chamber 3. When the coolant in the kettle body 1 drops below the normal water level, the pusher 8 drives the push plate 7 toward the water outlet 5, reducing the volume of coolant in the kettle body 1 and raising the coolant level. This allows the coolant in the kettle body 1 to continue to meet usage needs, thereby reducing the operator's need to add coolant to the expansion kettle. In this embodiment, the kettle body 1 is indented near the pusher 8, forming a chamber within the liquid discharge chamber 3 for the pusher 8, thereby reducing the volume occupied by the kettle body 1 as a whole and the pusher 8.

[0077] Reference Figure 2 and Figure 3 A pulling assembly 9 is installed on the side of the liquid pushing plate 7 away from the pushing member 8. The pulling assembly 9 is used to control the movement of the liquid pushing plate 7 toward the side close to the water outlet 5. The pulling assembly 9 includes a tension member 10, an inflation control member 11, and a connecting member 12. The tension member 10 is integrally arranged on the side of the liquid pushing plate 7 away from the pushing member 8. The tension member 10 is semi-annular. The inflation control member 11 is a spherical inflatable body. The inflation control member 11 is used to control the movement of the liquid pushing plate 7. A limit plate 13 is integrally arranged on the inner side wall of the liquid discharge chamber 3 near the water outlet 5. There are two limit plates 13, and the two limit plates 13 are symmetrically arranged about the inflation control member 11. The side of the limit plate 13 close to the inflation control member 11 is arc-shaped. The limit plate 13 is used to limit the movement of the inflation control member 11 along the length direction of the limit plate 13.

[0078] Reference Figure 2 and Figure 3The connecting member 12 is mounted on the inflation control member 11 and is used to rotatably connect the tension member 10. The connecting member 12 includes a connecting column 14, a mounting block 15 and a rotating block 16. The connecting column 14 is integrally arranged on the inflation control member 11 on the side close to the tension member 10. The mounting block 15 is used to be mounted with the connecting column 14, and the mounting block 15 is connected to the connecting column 14 by a thread. The rotating block 16 is integrally arranged on the side of the mounting block 15 away from the connecting column 14. The rotating block 16 is used to rotatably connect with the tension member 10. There are two rotating blocks 16 in total, and the two rotating blocks 16 are symmetrically arranged about the tension member 10. The sides of the two rotating blocks 16 close to each other are each provided with a rotating groove 17 for the tension member 10 to be placed and rotated. The side of the rotating block 16 away from the mounting block 15 is provided with a guide surface 18 for the tension member 10 to move into the rotating groove 17. The guide surface 18 is inclined from the tension member 10 to the rotating block 16 toward the middle position of the two rotating blocks 16. The guide surface 18 facilitates placement of the tension member 10 in the rotation groove 17 .

[0079] The use process of an expansion kettle according to the embodiment of the present application is as follows:

[0080] 1. The liquid level at the water outlet 5 is detected by the liquid level sensing device 6. When the coolant in the kettle body 1 drops below the normal water level range, the liquid level sensing device 6 issues an alarm and drives the liquid pushing plate 7 to move toward the water outlet 5 through the pushing member 8, thereby reducing the volume of the coolant placed in the kettle body 1 and raising the coolant level in the kettle body 1. When the coolant in the kettle body 1 drops below the normal water level range, the inflation control member 11 moves with the coolant in the kettle body 1 toward the bottom of the liquid discharge cavity 3, thereby pulling the liquid pushing plate 7 to move toward the water outlet 5, reducing the force required by the pushing member 8.

[0081] Reference Figure 4 Based on the same inventive concept, an embodiment of the present invention provides a method for controlling the water level of an expansion kettle, comprising:

[0082] Step S100, obtaining a liquid level detection value.

[0083] The liquid level detection value refers to the liquid level value currently detected at the water outlet 5 , and the liquid level detection value is obtained by detection by the liquid level sensing device 6 .

[0084] Step S200: Determine whether the liquid level detection value is within a preset liquid level reference interval. If yes, jump to step S100; if not, execute step S300.

[0085] The liquid level reference interval refers to the permissible range of liquid level variation at the water outlet 5 when the expansion kettle can be used normally. The liquid level reference interval is obtained by querying a database storing the liquid level reference interval.

[0086] By judging whether the liquid level detection value is within the preset liquid level reference interval, it is determined whether the currently detected liquid level value at the water outlet 5 can enable the expansion kettle to continue to be used normally.

[0087] When the liquid level detection value is within the preset liquid level reference interval, it indicates that the liquid level value at the water outlet 5 currently detected can enable the expansion kettle to continue to be used normally, so the process jumps to step S100 .

[0088] Step S300 , according to the correspondence between the liquid level detection value, the liquid level reference interval and the preset liquid level adjustment value, analyze and obtain the liquid level adjustment value corresponding to the liquid level detection value and the liquid level reference interval, and send the liquid level adjustment value to the pusher 8 .

[0089] The liquid level adjustment value refers to an adjustment value for adjusting the liquid level at the water outlet 5 , and the liquid level adjustment value is obtained by querying from a database storing liquid level adjustment values.

[0090] When the liquid level detection value is not within the preset liquid level reference interval, it means that the liquid level value currently detected at the water outlet 5 cannot allow the expansion kettle to continue to be used normally. Therefore, the liquid level adjustment value is obtained by analyzing the liquid level detection value and the liquid level reference interval, and the liquid level adjustment value is sent to the pusher 8, thereby controlling the pusher 8 to drive the liquid pushing plate 7 to move, changing the volume of the coolant placed in the kettle body 1, and restoring the coolant level in the kettle body 1 to the normal water level range, thereby continuing to use the expansion kettle normally and extending the service life of the expansion kettle.

[0091] exist Figure 4 After step S100 and before step S200, in order to further ensure the rationality of the liquid level detection value, it is necessary to perform further separate analysis and calculation after obtaining the liquid level detection value. Figure 5 The steps shown are explained in detail.

[0092] Reference Figure 5 The steps after obtaining the liquid level detection value and before determining whether the liquid level detection value is within a preset liquid level reference interval include the following steps:

[0093] In step S110 , according to the correspondence between the liquid level deviation value, the liquid level reference interval and the preset preliminary adjustment value, a preliminary adjustment value corresponding to the liquid level deviation value and the liquid level reference interval is analyzed and obtained.

[0106] Step S111, determine whether the liquid level detection value is greater than the maximum value corresponding to the liquid level reference interval. If yes, execute step S112; if not, execute step S113.

[0107] Here, by judging whether the liquid level detection value is greater than the maximum value corresponding to the liquid level reference interval, it is judged whether the liquid level at the water outlet 5 needs to be lowered and adjusted subsequently.

[0109] The lowering adjustment value refers to an adjustment value for lowering the liquid level at the water outlet 5 .

[0110] When the liquid level detection value is greater than the maximum value corresponding to the liquid level reference interval, it indicates that the liquid level at the water outlet 5 needs to be subsequently lowered and adjusted. Therefore, the difference between the liquid level detection value and the maximum value corresponding to the liquid level reference interval is analyzed and calculated, and the difference between the liquid level detection value and the maximum value corresponding to the liquid level reference interval is used as the reduction adjustment value, and the reduction adjustment value is used as the liquid level adjustment value, so as to control the liquid level at the water outlet 5 to reduce and adjust, thereby improving the accuracy of the obtained liquid level adjustment value.

[0112] The raising adjustment value refers to the adjustment value for raising the liquid level at the water outlet 5 .

[0113] When the liquid level detection value is not greater than the maximum value corresponding to the liquid level reference interval, it indicates that the liquid level at the water outlet 5 needs to be subsequently adjusted to increase. Therefore, the difference between the liquid level detection value and the minimum value corresponding to the liquid level reference interval is analyzed and calculated, and the difference between the liquid level detection value and the minimum value corresponding to the liquid level reference interval is used as the increase adjustment value, and the increase adjustment value is used as the liquid level adjustment value, so as to control the increase of the liquid level at the water outlet 5 and improve the accuracy of the obtained liquid level adjustment value.

[0114] exist Figure 6 After step S112 or step S113, in order to further ensure the rationality of the liquid level adjustment value, it is necessary to perform further separate analysis and calculation after the lowering adjustment value is used as the liquid level adjustment value or after the raising adjustment value is used as the liquid level adjustment value.

[0117] The auxiliary liquid level detection position point refers to the position point where the inflation control component 11 is located, and the auxiliary liquid level detection position point is obtained by detection via a position sensor preset in the inflation control component 11 .

[0118] Step S1122 , according to the correspondence between the auxiliary liquid level detection position point and the preset auxiliary detection actual liquid level value, analyze and obtain the auxiliary detection actual liquid level value corresponding to the auxiliary liquid level detection position point.

[0119] The auxiliary detection actual liquid level value refers to the actual liquid level value when the auxiliary detection is performed on the liquid level at the water outlet 5 , and the auxiliary detection actual liquid level value is obtained by querying from a database storing the auxiliary detection actual liquid level values.

[0120] The actual liquid level value of the auxiliary detection is obtained by analyzing the auxiliary liquid level detection position point, so as to facilitate the subsequent use of the actual liquid level value of the auxiliary detection.

[0121] Step S1123: Determine whether the actual auxiliary detection liquid level value is consistent with the preset auxiliary detection reference liquid level value. If yes, execute step S1124; if not, execute step S1125.

[0122] The auxiliary detection reference liquid level value is the reference liquid level value that the liquid level at the water outlet 5 needs to be at when performing auxiliary detection on the liquid level at the water outlet 5 . The auxiliary detection reference liquid level value is obtained by querying a database storing the auxiliary detection reference liquid level value.

[0123] By judging whether the actual liquid level value of the auxiliary detection is consistent with the preset auxiliary detection reference liquid level value, it is judged whether the liquid level value obtained by the auxiliary detection of the liquid level at the water outlet 5 is accurate.

[0124] Step S1124, continue to output the liquid level adjustment value.

[0125] Among them, when the actual liquid level value of the auxiliary detection is consistent with the preset auxiliary detection reference liquid level value, it means that the liquid level value obtained by the auxiliary detection of the liquid level at the water outlet 5 at this time is accurate, which further proves that the liquid level detection at the water outlet 5 at this time is accurate, so the liquid level adjustment value continues to be output.

[0126] Step S1125 , analyzing and calculating the difference between the actual liquid level value of the auxiliary detection and the auxiliary detection reference liquid level value based on the actual liquid level value of the auxiliary detection and the auxiliary detection reference liquid level value, and using the difference as the auxiliary detection deviation liquid level value.

[0127] The auxiliary detection deviation liquid level value refers to the deviation value generated between the actual liquid level value and the reference liquid level value when the auxiliary detection is performed on the liquid level at the water outlet 5 .

[0128] When the actual liquid level value of the auxiliary detection is inconsistent with the preset auxiliary detection reference liquid level value, it means that the liquid level value obtained by the auxiliary detection of the liquid level at the water outlet 5 is inaccurate. Therefore, the difference between the actual liquid level value of the auxiliary detection and the auxiliary detection reference liquid level value is analyzed and calculated, and the difference between the actual liquid level value of the auxiliary detection and the auxiliary detection reference liquid level value is used as the auxiliary detection deviation liquid level value, so as to facilitate the subsequent use of the auxiliary detection deviation liquid level value.

[0129] Step S1126, according to the correspondence between the auxiliary detection deviation liquid level value and the preset auxiliary detection adjustment liquid level value, analyze and obtain the auxiliary detection adjustment liquid level value corresponding to the auxiliary detection deviation liquid level value, and add the auxiliary detection adjustment liquid level value to the liquid level adjustment value to form a new liquid level adjustment value.

[0130] Among them, the auxiliary detection adjustment liquid level value refers to the adjustment value that needs to be further adjusted after the auxiliary detection of the liquid level at the water outlet 5, and the auxiliary detection adjustment liquid level value is queried and obtained from a database storing the auxiliary detection adjustment liquid level value.

[0131] The auxiliary detection adjustment liquid level value is obtained by analyzing the auxiliary detection deviation liquid level value, and the auxiliary detection adjustment liquid level value is added to the liquid level adjustment value to form a new liquid level adjustment value, so that the liquid level adjustment value is corrected according to the actual position of the inflation control component 11, reducing the impact of the error generated by the detection of the liquid level sensing device 6, thereby improving the accuracy of the obtained liquid level adjustment value.

[0136] The initial liquid level value of the auxiliary detection is obtained by analyzing the auxiliary liquid level detection position point, so as to facilitate the subsequent use of the initial liquid level value of the auxiliary detection.

[0137] Step S11222 , analyzing and acquiring a vehicle tilt assisting detection influence value corresponding to the vehicle tilt angle value according to a correspondence between the vehicle tilt angle value and a preset vehicle tilt assisting detection influence value.

[0138] The vehicle tilt auxiliary detection impact value refers to the impact value on the auxiliary detection after the vehicle tilts, and the vehicle tilt auxiliary detection impact value is obtained by querying from a database storing the vehicle tilt auxiliary detection impact value.

[0139] The vehicle tilt angle value is analyzed to obtain the vehicle tilt auxiliary detection impact value, thereby facilitating the subsequent use of the vehicle tilt auxiliary detection impact value.

[0140] Step S11223, based on the correspondence between the auxiliary detection initial liquid level value, the vehicle tilt auxiliary detection influence value and the preset auxiliary detection final liquid level value, analyze and obtain the auxiliary detection final liquid level value corresponding to the auxiliary detection initial liquid level value and the vehicle tilt auxiliary detection influence value, and use the auxiliary detection final liquid level value as the auxiliary detection actual liquid level value.

[0141] The auxiliary detection final liquid level value refers to the final liquid level value when the auxiliary detection is performed on the liquid level at the water outlet 5 , and the auxiliary detection final liquid level value is obtained by querying from a database storing the auxiliary detection final liquid level value.

[0142] The final liquid level value of the auxiliary detection is obtained by analyzing the initial liquid level value of the auxiliary detection and the auxiliary detection influence value of the vehicle tilt, and the final liquid level value of the auxiliary detection is used as the actual liquid level value of the auxiliary detection, thereby reducing the impact of the vehicle tilt on the auxiliary detection and improving the accuracy of the obtained actual liquid level value of the auxiliary detection.

[0143] exist Figure 7 In step S1126, in order to further ensure the rationality of the auxiliary detection adjustment liquid level value, it is necessary to further analyze and calculate the auxiliary detection adjustment liquid level value. Figure 9 The steps shown are explained in detail.

[0144] Reference Figure 9 According to the corresponding relationship between the auxiliary detection deviation liquid level value and the preset auxiliary detection adjustment liquid level value, analyzing and obtaining the auxiliary detection adjustment liquid level value corresponding to the auxiliary detection deviation liquid level value includes the following steps:

[0145] Step S11261: Analyze and obtain the initial value of the adjusted liquid level corresponding to the auxiliary detection deviation liquid level value based on the corresponding relationship between the auxiliary detection deviation liquid level value and the preset initial value of the adjusted liquid level.

[0147] The initial value of the adjusted liquid level is obtained by analyzing the auxiliary detection deviation liquid level value, so as to facilitate the subsequent use of the initial value of the adjusted liquid level.

[0148] Step S11262: Determine whether the auxiliary detection deviation liquid level value is greater than a preset deviation liquid level reference value. If yes, execute step S11263; if no, execute step S11266.

[0149] The deviation liquid level reference value refers to a reference adjustment value required for further adjustment of the liquid level after auxiliary detection of the liquid level at the water outlet 5 . The deviation liquid level reference value is obtained by querying a database storing the deviation liquid level reference value.

[0150] By judging whether the auxiliary detection deviation liquid level value is greater than the preset deviation liquid level reference value, it is judged whether the adjustment value required for further adjustment of the liquid level after the auxiliary detection of the liquid level at the water outlet 5 is too large.

[0151] Step S11263: Analyze and calculate the difference between the auxiliary detection deviation liquid level value and the deviation liquid level reference value based on the auxiliary detection deviation liquid level value and use it as the deviation liquid level deviation value.

[0152] The deviation liquid level deviation value refers to a deviation value generated by an adjustment value required to further adjust the liquid level after auxiliary detection of the liquid level at the water outlet 5 .

[0153] When the auxiliary detection deviation liquid level value is greater than the preset deviation liquid level reference value, it means that the adjustment value required for further adjustment of the liquid level after auxiliary detection of the liquid level at the water outlet 5 is too large, so the difference between the auxiliary detection deviation liquid level value and the deviation liquid level reference value is analyzed and calculated, and the difference between the auxiliary detection deviation liquid level value and the deviation liquid level reference value is used as the deviation liquid level deviation value, so as to facilitate the subsequent use of the deviation liquid level deviation value.

[0154] Step S11264 , according to the correspondence between the deviation liquid level deviation value and the preset adjustment liquid level deviation adjustment value, analyze and obtain the adjustment liquid level deviation adjustment value corresponding to the deviation liquid level deviation value.

[0155] The liquid level deviation adjustment value is an adjustment value adjusted after a deviation occurs in the adjustment value that requires further adjustment of the liquid level after auxiliary detection of the liquid level at the water outlet 5. The liquid level deviation adjustment value is obtained from a database storing the liquid level deviation adjustment value.

[0156] The adjustment level deviation adjustment value is obtained by analyzing the deviation level deviation value, so as to facilitate the subsequent use of the adjustment level deviation adjustment value.

[0158] The final value of the adjusted liquid level refers to the final adjusted value required for further adjustment of the liquid level after auxiliary detection of the liquid level at the water outlet 5 , and the final value of the adjusted liquid level is obtained by querying from a database storing the final value of the adjusted liquid level.

[0159] The final value of the adjusted liquid level is obtained by analyzing the adjustment value of the adjusted liquid level deviation and the initial value of the adjusted liquid level, and the final value of the adjusted liquid level is used as the auxiliary detection adjustment liquid level value. Therefore, when the adjustment value that requires further adjustment of the liquid level after the auxiliary detection of the liquid level at the water outlet 5 is too large, the auxiliary detection adjustment liquid level value is adjusted, so that the adjustment value that requires further adjustment of the liquid level after the auxiliary detection of the liquid level at the water outlet 5 is not easy to be too large, and the accuracy of the obtained auxiliary detection adjustment liquid level value is improved.

[0160] Step S11266: directly use the initial value of the adjusted liquid level as the auxiliary detection adjusted liquid level value.

[0161] Among them, when the auxiliary detection deviation liquid level value is greater than the preset deviation liquid level reference value, it means that the adjustment value required for further adjustment of the liquid level after auxiliary detection of the liquid level at the water outlet 5 is too large, so the initial value of the adjusted liquid level is directly used as the auxiliary detection adjustment liquid level value.

[0162] exist Figure 9 In step S11264, in order to further ensure the rationality of the adjusted liquid level deviation adjustment value, it is necessary to further analyze and calculate the adjusted liquid level deviation adjustment value. Figure 10 The steps shown are explained in detail.

[0163] Reference Figure 10 According to the correspondence between the deviation liquid level deviation value and the preset adjustment liquid level deviation adjustment value, analyzing and obtaining the adjustment liquid level deviation adjustment value corresponding to the deviation liquid level deviation value includes the following steps:

[0164] Step S112641 , according to the correspondence between the deviation liquid level deviation value and the preset adjustment liquid level deviation preliminary adjustment value, analyze and obtain the adjustment liquid level deviation preliminary adjustment value corresponding to the deviation liquid level deviation value.

[0165] Among them, the preliminary adjustment value of the liquid level deviation refers to the preliminary deviation value generated by the adjustment value that needs to be further adjusted after auxiliary detection of the liquid level at the water outlet 5. The preliminary adjustment value of the liquid level deviation is obtained by querying from the database storing the preliminary adjustment value of the liquid level deviation.

[0166] The preliminary adjustment value of the adjustment level deviation is obtained by analyzing the deviation liquid level deviation value, so as to facilitate the subsequent use of the preliminary adjustment value of the adjustment liquid level deviation.

[0167] Step S112642: Determine whether the deviation value of the liquid level is greater than a preset deviation reference value. If yes, execute step S112643; if no, execute step S112644.

[0168] Among them, the deviation liquid level deviation reference value refers to the reference deviation value generated by the adjustment value that needs to be further adjusted for the liquid level after auxiliary detection of the liquid level at the water outlet 5. The deviation liquid level deviation reference value is obtained by querying from a database that stores the deviation liquid level deviation reference value.

[0169] By judging whether the deviation value of the deviation liquid level is greater than the preset deviation liquid level deviation reference value, it is judged whether the deviation value generated by the adjustment value required for further adjustment of the liquid level after auxiliary detection of the liquid level at the water outlet 5 is too large.

[0170] Step S112643: Output the freeze alarm information to the terminal held by the operator.

[0171] The jam alarm information refers to a prompt message used to indicate a jam between the limit plate 13 and the inflation control member 11. The jam alarm information is retrieved from a database storing jam alarm information. The operator's terminal refers to a terminal held by the operator that can receive information. The operator's terminal can be a laptop or a mobile phone.

[0172] When the deviation liquid level deviation value is greater than the preset deviation liquid level deviation reference value, it means that the deviation value generated by the adjustment value required for further adjustment of the liquid level after auxiliary detection of the liquid level at the water outlet 5 is too large, which further indicates that a jam occurs between the limit plate 13 and the inflation control component 11, so a jam alarm message is output to the terminal held by the operator.

[0173] Step S112644: Using the preliminary adjustment value of the liquid level deviation as the adjustment value of the liquid level deviation.

[0174] Among them, when the deviation liquid level deviation value is not greater than the preset deviation liquid level deviation reference value, it means that the deviation value generated by the adjustment value required for further adjustment of the liquid level after auxiliary detection of the liquid level at the water outlet 5 is not too large, and further indicates that there is no jamming between the limit plate 13 and the inflation control component 11, so the preliminary adjustment value of the adjustment liquid level deviation is used as the adjustment liquid level deviation adjustment value.
