[0036] <Example>

[0037] The present embodiment proposes an intelligent air filter instrument management system, which can be used in automobiles or motorcycles, especially on motorcycles, and includes an intelligent air filter 10 and an instrument 20. The intelligent air filter 10 is generally arranged in the middle of the motorcycle frame and connected to the engine. The instrument 20 is installed between the two handlebars on the front of the motorcycle to facilitate user observation while driving. The intelligent air filter 10 and the instrument 20 are communicatively connected. The instrument 20 can display relevant data and usage status of the intelligent air filter 10, so that the user can observe the current status of the air filter in time, provide the user with timely maintenance prompts, and avoid engine damage caused by negligence of the user.

[0038] Specifically, Figure 2-Figure 5 As shown, the intelligent air filter 10 includes an air outlet box 30, an air inlet box 40 and a filter assembly 50. The air outlet box 30 has an air outlet cavity 31 and is equipped with a clean air outlet pipe 32. The air inlet box 40 is installed on the air outlet box 30, has an air inlet cavity 41, and is equipped with a dirty air inlet pipe 42. The filter assembly 50 is installed between the air inlet box 30 and the air outlet box 40, and is used to filter the dirty air from the dirty air inlet pipe 42. The filtered clean air enters the air outlet cavity 31 and finally goes out from the clean air outlet pipe 32. Among them, the clean air outlet pipe 32 has an internal part 321 extending into the air outlet cavity and an exposed part 322 exposed to the air outlet box 30. The open end of the internal part 321 extends toward the filter assembly 50, and the exposed part 322 is equipped with a data collector 61.

[0039] The filter assembly 50 includes a filter element 51 and a mounting frame 52. The mounting frame 52 is used to mount the filter element 51 between the air outlet box 30 and the air inlet box 40. The air outlet box 30 and the air inlet box 40 are provided with openings of matching shapes at opposite ends. The mounting frame 52 has a shape matching the openings. The openings of the air outlet box 30 and the air inlet box 40 are both recessed inward to form fixing grooves 301 and 401. Figure 4 As shown, the mounting frame 52 has a fixed body 521 and a mounting hole 522 opened in the middle of the fixed body 521. The two sides of the edge of the fixed body 521 protrude outward to form fixed flanges 523. The fixed flanges 523 on both sides are respectively embedded in the two fixed grooves 301 and 401. The air outlet box 30 and the air inlet box 40 are fixed by screws, so that the air outlet box 30, the mounting frame 52 and the air inlet box 40 are fixed together. In order to enhance the sealing performance of the connection structure, a sealing ring can be added when the fixed flange 523 cooperates with the two fixed grooves 301 and 401.

[0040] like Figure 3As shown, in order to enhance the stability of the installation of the mounting frame 52, a limiting piece 524 is formed on the outer edge of the fixed body 521, and a limiting hole 302 for the limiting piece 524 to extend into is correspondingly formed on the air outlet box 30 or the air inlet box 40. In this embodiment, the limiting hole 302 is set on the air outlet box 30. During installation, the limiting piece 524 is first inserted into the limiting hole 302, and then the fixing flange 523 is embedded in the fixing groove 301 to complete the installation between the mounting frame 52 and the air outlet box 30, and then the air inlet box 40 is covered along the fixing flange 523.

[0041] With the mounting frame 52 as the boundary, an air outlet cavity 31 is formed between one side of the mounting frame 52 and the air outlet box 30, and an air inlet cavity 41 is formed between the other side and the air inlet box 40. A mounting hole 522 in the middle of the mounting frame 52 connects the air inlet cavity 41 and the air outlet cavity 31. The filter assembly 50 is installed on the mounting hole 522, so that the dirty gas in the air inlet cavity 41 can enter the air outlet cavity 31 after being filtered.

[0042] like Figure 5 As shown, the filter element 51 includes a fixing plate 511, a filter screen 512 and a filter paper 513. The fixing plate 511 is fixed to the side of the mounting frame 52 facing the air outlet cavity. The filter screen 512 covers the side of the fixing plate away from the air outlet cavity. The filter paper 513 is installed in the mounting hole 522 of the mounting frame 52 and is located on the side of the filter screen 512 facing the air inlet cavity. The filter screen 512 has a plurality of filter holes arranged vertically and horizontally. The edge of the filter screen 512 is folded toward the side where the air outlet cavity is located to form a wrapping 5121 wrapped around the outer peripheral edge of the fixing plate. Figure 4 As shown, two pairs of symmetrically arranged blocks 5221 are formed on the inner peripheral wall of the mounting hole 522 of the mounting frame 52, and a V-shaped groove is opened in the middle of the block 5221. The filter paper 513 is inserted into the V-shaped groove for installation, and installation and removal are very convenient. The fixing plate 511 and the filter screen 512 are placed on the filter rear side of the filter paper 513 to support the filter paper 513.

[0043] The fixing body 521 is formed with a mounting portion 525 on one side of the mounting hole 522 for mounting the dirty air intake pipe 42. Figure 4As shown, the mounting portion 525 spans across the fixed body 521, and is in the shape of a groove that is sunken toward the side where the air outlet cavity 31 is located. A limiting convex edge 5251 that protrudes toward the side where the air inlet cavity 41 is located is provided in the middle of the groove. A fixing portion 43 is formed on the inner wall of the air intake box 40 corresponding to the mounting portion 525. The shape and structure of the fixing portion 43 are basically the same as those of the mounting portion 525, and is in the shape of a groove that is sunken toward the inner wall of the air intake box 40. A limiting convex edge 431 that protrudes toward the side where the mounting portion 525 is located is provided in the middle of the groove. A partition portion 421 is integrally or separately provided on the dirty air intake pipe 42 (in the present embodiment, it is integrally provided). The edges on both sides of the partition portion 421 correspond to the fixing portion 43 and the mounting portion 525 for insertion, and a limiting card groove for the limiting convex edges 5251 and 431 to be inserted is provided at the edge of the partition portion 421.

[0044] like Figure 5 As shown, the air inlet cavity 41 is divided by a partition 421 to form an outer air inlet cavity 411 and an inner air inlet cavity 412. The dirty air inlet pipe 42 has an outer visceral pipe portion 422 extending into the outer air inlet cavity 411 and an inner visceral pipe portion 423 extending into the inner air inlet cavity 412. A main air inlet 44 is provided on the air inlet box 40. A dirty air inlet 424 is provided at one end of the outer visceral pipe portion 422 away from the inner visceral pipe portion 423, and a dirty air outlet 425 is provided at the tail end of the inner visceral pipe portion 423 (i.e., the end away from the outer visceral pipe portion 422). A sewage outlet 44 leading to the outside is also provided on the air inlet box 40 at the inner air inlet cavity 422, which is used to discharge larger dust impurities and wastewater filtered out.

[0045] like Figure 2 As shown, taking the plane where the connecting surfaces of the air inlet box 40 and the air outlet box 30 are located as the reference plane, the mounting hole 522 of the mounting frame 52 is arranged at an angle, that is, the filter element 51 installed in the mounting hole 522 is arranged at an angle, and has a filter element low point 51a and a filter element high point 51b, the height of the filter element high point 51b is higher than the filter element low point 51a, the dirty air inlet pipe 42 is also arranged at an angle, and the inclination direction is the same as the inclination direction of the filter element 51 (that is, on the reference plane, the height of the dirty air outlet 425 is higher than the height of the dirty air inlet 424), the length of the visceral pipe part 423 is almost equal to half of the length of the filter element, or even greater than half of the length of the filter element, that is to say, the dirty air outlet 425 is closer to the filter element high point 51b, so that when the dirty air enters and is ready to be filtered, it can first enter from the filter element high point 51b, and then gradually penetrate to the filter element low point 51a, so that the gas can be more fully filtered, thereby improving the filtering effect. The clean air inlet 3211 on the built-in part 321 of the clean air outlet pipe 32 in the air outlet box 30 is set toward the low point 51a of the filter element, so that the gas filtered by the filter element can enter the clean air outlet pipe 32 along the clean air inlet 3211, and then be discharged into the engine along the clean air outlet pipe 32.

[0046] When the air filter is working, it generates negative pressure to suck in external dirty gas from the main air inlet 44 for filtration. A data collector 61 is installed on the exposed part 322 of the clean air outlet pipe 32, which can collect the negative pressure value when the air filter is working, and then convert the negative pressure value into a related voltage signal through the data collector 61 and send it to the instrument.

[0047] In this embodiment, the instrument 20 has an instrument mounting bracket 21 and a display screen 22 and a controller 23 mounted on the instrument mounting bracket 21. The instrument mounting bracket 21 includes a mounting frame 211 and a back cover 212. The display screen 22 is mounted on one side of the mounting frame 211, and the controller 23 is mounted on the other side. The back cover 212 is arranged on the side of the mounting frame 211 away from the display screen 22, and the controller 23 is wrapped between the back cover 212 and the mounting frame 211. A chip 24 is mounted on the edge of the controller 23. The mounting frame 211 has a heat dissipation area 213. The chip 24 is fixed to the heat dissipation area 213 by a pair of fixing members (screws 241). The heat dissipation area 213 has a plurality of heat sinks, and the heat sinks include an inner heat sink 2131 located inside the mounting frame 211 and an outer heat sink 2132 exposed to the mounting frame 211. Since the chip 24 is prone to generate a large amount of heat during operation, installing the chip 24 close to the heat dissipation area can effectively and quickly dissipate the heat of the chip 24, thereby playing a better protective role.

[0048] The chip 24 contains a data receiving module and a data processing module. The data receiving module is used to receive the voltage signal transmitted from the data collector 61 installed on the clean air outlet pipe of the air filter. The data processing module is used to analyze and count the voltage signal and predict the use status of the air filter.

[0049] The data collected by the data collector 61 include the negative pressure value in the clean air outlet pipe 32, and the negative pressure value is converted into a real-time voltage signal by the data collector 61. The processing module has at least a storage module, a conversion module and a judgment module. The storage module stores an analog voltage signal in advance. The conversion module converts the pre-stored analog voltage signal and the real-time voltage signal into an analog digital signal and a real-time digital signal respectively. The judgment module compares the analog digital signal with the real-time digital signal and determines whether the analog digital signal and the real-time digital signal are the same, and then judges the current usage status of the air filter.

[0050] Among them, the air filter mainly includes the following usage states:

[0051] 1. Maintenance status: a red air filter logo and the words "Please maintain the air filter in time" will appear on the display screen, reminding the user to maintain the air filter in time;

[0052] 2. Replacement status: a yellow air filter logo and the words "Please replace the air filter in time" will appear on the display screen, prompting the user to replace the air filter in time;

[0053] 3. In normal status, a green air filter logo appears on the display screen, prompting the user that the current air filter can be used normally.

[0054] In addition to displaying the above status, the display screen will also display the information values ​​of the air filter, including the current intake volume, negative pressure value, warning value and other data (as shown in the figure).

[0055] In this embodiment, Figure 6 As shown, the management system for controlling the air filter by the instrument controller in the motorcycle includes a data collector 61 (preferably a micro-pressure sensor) installed on the air filter and a data processing controller 23 arranged inside the instrument mounting bracket 21, wherein the data collector 61 has a data acquisition unit, an information conversion unit and an information communication unit, the data acquisition unit is used to collect the real-time negative pressure value in the air filter, the information conversion unit is used to convert the collected real-time negative pressure value into a real-time voltage signal, and the information communication unit transmits the real-time voltage signal to the data processing controller in the instrument.

[0056] The data processing controller has a signal receiving module and a signal processing module. The signal processing module includes an information storage unit, an information conversion unit, an information comparison unit and a prompt information generation unit. The information receiving module has an information acquisition unit for acquiring a real-time voltage signal generated from the data acquisition device 61. The information storage unit stores an analog voltage signal in advance. The information conversion unit converts the analog voltage signal and the real-time voltage signal into an analog digital signal and a real-time digital signal respectively. The information comparison unit is used to compare the analog digital signal with the real-time digital signal. The prompt information generation unit generates the current air filter usage status from the preset air filter usage status according to the comparison result, and displays the usage status on the display screen 22 of the instrument.

[0057] like Fig.13 and Fig.14 As shown, for example, the signal receiving module and the signal processing module can be implemented as a main control circuit and a power interface circuit, wherein the main control circuit includes a main control chip U12 (i.e., the above-mentioned chip 24), an RTC clock circuit, a reset circuit, etc., wherein the model of the main control chip U12 is AMT630H-V100-128, which has pins 1 to 129.

[0058] The power interface circuit includes a power interface J5, whose model is CON-26, and has pins 1 to 26, which are used to transmit power signals and provide power support. Its pin 26 is grounded, and pin 25 is connected to a 5V power supply.

[0059] like Fig.15As shown, for example, the data collector 61 may include a sensor AD detection circuit, which includes resistors R74 to R76, a capacitor C76, and an electrostatic protection diode ESD6, wherein the model of the diode ESD6 is BHS4037C, the resistance values ​​of the resistors R74 and R75 are 200Ω, and the resistance value of the resistor R76 is 4.7KΩ.

[0060] Among them, one end of the resistor R76 is connected to the pin 21 of the power interface J5, and the other end of the resistor R76 is connected to the pin 25 (general IO pin) of the control chip U12. After the resistors R74 and R75 are connected in parallel, one end is connected to the data acquisition unit of the data acquisition device 61 (marked as D3.3V in the figure), and the other end is connected to the above-mentioned one end of the resistor R76. One end of the capacitor C76 is connected to the above-mentioned other end of the resistor R76, and the other end of the capacitor C76 is grounded. One end of the diode ESD6 is connected to the above-mentioned other end of the resistor R76, and the other end of the diode ESD6 is grounded.

[0061] Therefore, the sensor AD detection circuit can collect and sample the real-time negative pressure value used by the data acquisition unit of the data acquisition device 61 to obtain a corresponding voltage signal, and provide the voltage signal to the main control chip U12, which then further processes the voltage signal.

[0062] Based on the above intelligent air filter instrument management system, the workflow of the instrument controller to control the air filter includes the following steps:

[0063] Step S1, the data acquisition unit in the data acquisition device 61 acquires the real-time negative pressure value in the clean gas outlet pipe 32;

[0064] Step S2, the information conversion unit in the data collector 61 converts the collected real-time negative pressure value into a real-time voltage signal;

[0065] Step S3, the information communication unit in the data collector 61 sends the real-time voltage signal to the instrument chip 24;

[0066] Step S4, the signal receiving module in the chip 24 receives the real-time voltage signal sent from the data collector 61;

[0067] Step S5, the information conversion unit converts the analog voltage signal and the real-time voltage signal stored in the information storage unit into an analog digital signal and a real-time digital signal respectively;

[0068] Step S6, the information comparison unit compares the simulated digital signal with the real-time digital signal;

[0069] Step S7, the prompt information generating unit generates the current air filter usage status from the preset air filter usage status according to the comparison result;

[0070] Step S8: The current air filter usage status is displayed on the instrument display screen.

[0071] Embodiment technical effect:
