[0042] The embodiment of the present application provides a liquid inlet detection sensor, which can be used for liquid inlet detection of detected equipment such as vehicles and air conditioners, wherein the liquid in the detected equipment detected by the liquid inlet detection sensor is water or other conductive liquids.

[0043] Reference Figures 1 to 3 , the liquid inlet detection sensor comprises:

[0044] A main body 1, a connecting part 2 and a sensing part 3 connected to both sides of the main body 1, the liquid inlet detection sensor can be electrically connected to the detected device through the connecting part 2, the sensing part 3 includes a first probe 31 and a second probe 32 arranged at intervals, when the liquid level in the liquid inlet detection sensor is higher than a predetermined threshold, the first probe 31 is connected to the second probe 32 and transmits a liquid inlet signal to the connecting part 2.

[0045] like Figure 1 As shown, the liquid inlet detection sensor can be electrically connected to the detected device through the connection part 2 on one side of the body 1, so that the liquid inlet detection sensor can detect the liquid inflow situation of the corresponding detected device, thereby improving its waterproof function. For example, when the liquid inlet detection sensor is electrically connected to the vehicle through the connection part 2, the liquid inflow situation in the vehicle can be detected; when the liquid inlet detection sensor is electrically connected to the air conditioner through the connection part 2, the liquid inflow situation in the air conditioner can be detected. Among them, the connection part 2 may include a connector, and the connector is used to realize the transmission of electrical signals. Different connectors can be selected or designed according to the detected device.

[0046] Among them, the main body 1, the connecting parts 2 and the sensing parts 3 on both sides of the main body 1 can be a split design, which is convenient for independent maintenance and replacement of each part; the main body 1, the connecting parts 2 and the sensing parts 3 on both sides of the main body 1 can also be an integrated design, which can simplify the production process and reduce production costs.

[0047] like Figures 1 to 3As shown, the sensing part 3 includes a first probe 31 and a second probe 32 arranged at intervals, that is, there is a certain distance between the first probe 31 and the second probe 32, and the first probe 31 and the second probe 32 are respectively electrically connected to the connecting part 2 to facilitate the transmission of the liquid inlet signal. Among them, the outer surface of the first probe 31 and the outer surface of the second probe 32 can be metal-plated respectively, so that the first probe 31 and the second probe 32 can be electrically connected to the connecting part 2 respectively and stably transmit electrical signals.

[0048] Specifically, when the liquid level in the liquid inlet detection sensor is low (lower than the sensing height of the liquid inlet detection sensor), the first probe 31 and the second probe 32 are disconnected, and at this time, the first probe 31 and the second probe 32 cannot transmit electrical signals to the connecting part 2; when the liquid level in the liquid inlet detection sensor is high (higher than the sensing height of the liquid inlet detection sensor), the first probe 31 and the second probe 32 can be connected through the conductive liquid, and at this time, the first probe 31 and the second probe 32 transmit the liquid inlet signal to the connecting part 2, and then the connecting part 2 transmits the received liquid inlet signal to the control unit of the detected device, so as to improve the waterproof function of the detected device.

[0049] The predetermined threshold is the sensing height of the liquid inlet detection sensor, that is, the critical height at which the first probe 31 and the second probe 32 can be connected. When the liquid level is higher than (or equal to) the predetermined threshold, the first probe 31 and the second probe 32 can be connected through the conductive liquid; when the liquid level is lower than the predetermined threshold, the first probe 31 and the second probe 32 remain disconnected.

[0050] In addition, in other embodiments, the connection and disconnection between the first probe 31 and the second probe 32 can also be achieved by mechanical means. For example, a conductive structure that can be controlled by mechanical means can be designed, and when the liquid level is higher than (or equal to) a predetermined threshold, the conductive structure can be connected between the first probe 31 and the second probe 32, and the first probe 31 and the second probe 32 are connected; when the liquid level is lower than the predetermined threshold, the conductive structure is disconnected, and the first probe 31 and the second probe 32 are disconnected.

[0051] For example, when the liquid inlet detection sensor is applied to a vehicle, the liquid inlet detection sensor can be installed on the engine and detect the liquid inlet condition of the engine compartment. When the liquid level in the engine compartment is higher than a predetermined threshold, the first probe 31 and the second probe 32 can be connected through the conductive liquid, and the liquid inlet signal is transmitted to the vehicle electronic control unit through the connecting part 2. The vehicle controller interacting with the vehicle electronic control unit can start the waterproof mode of the engine based on this, thereby improving the driving safety of the vehicle.

[0052] Optionally, the connecting portion 2 includes a connector 22 , and the connector 22 has a first electrical connection end 221 , and the first electrical connection end 221 is used to be electrically connected to a third electrical connection end of the detected device.

[0053] like Figure 1 and Figure 3 As shown, the connector 22 is the core component of the electrical connection of the connection part 2, and it can be electrically connected to the third electrical connection end of the detected device through the first electrical connection end 221. Among them, the first electrical connection end 221 and the third electrical connection end can be compatible wiring terminals, so that the connection part 2 forms an electrical connection with the detected device, and can also ensure a fast, stable and reliable connection between the connection part 2 and the detected device, ensuring the transmission of signals or currents.

[0054] In addition, the first electrical connection terminal 221 and the third electrical connection terminal are adapted to each other, which can improve the accuracy and compatibility of the electrical connection between the connecting part 2 and the detected device, and can also avoid abnormalities such as connection failure or signal loss due to interface mismatch, thereby improving the detection reliability of the liquid inlet detection sensor.

[0055] Optionally, the body 1 has a through hole, the connector 22 and the sensing portion 3 are located at two opposite sides of the through hole, and the first probe 31 and the second probe 32 can pass through the through hole and be electrically connected to the connector 22 .

[0056] Specifically, the through hole on the body 1 allows the first probe 31 and the second probe 32 on one side to pass through the through hole conveniently and form an electrical connection with the connector 22 on the other side. This design optimizes the spatial structure of the liquid inlet detection sensor and also makes the entire liquid inlet detection sensor structure more compact and reasonable.

[0057] In addition, the connector 22 and the sensing part 3 are respectively located at two opposite sides of the through hole, which also ensures the stability and reliability of the electrical connection between the first probe 31 and the second probe 32 and the connector 22. During the detection process of the liquid inlet detection sensor, the first probe 31 and the second probe 32 can stably pass through the through hole and contact the connector 22, reducing the risk of poor connection or disconnection due to position displacement or shaking, thereby improving the accuracy and stability of the liquid inlet detection sensor.

[0058] Optionally, the first probe 31 includes a first sensing segment 311, the second probe 32 includes a second sensing segment 321, and the first sensing segment 311 and the second sensing segment 321 are arranged at intervals;

[0059] When the liquid level in the liquid inlet detection sensor is higher than the predetermined threshold, the first sensing segment 311 and the second sensing segment 321 are connected through the conductive liquid.

[0060] like Figure 2 As shown, the first sensing segment 311 and the second sensing segment 321 are used to sense the liquid level of the inflow. When the liquid level in the inflow detection sensor is higher than a predetermined threshold, the first sensing segment 311 and the second sensing segment 321 can be connected through the conductive liquid, and the liquid inflow signal is transmitted to the electrically connected connecting portion 2, and then transmitted to the control unit of the detected device through the connecting portion 2, so as to improve the waterproof function of the detected device.

[0061] Among them, there is a gap between the first sensing segment 311 and the second sensing segment 321, that is, there is a certain distance between the first sensing segment 311 and the second sensing segment 321, which can ensure that the first sensing segment 311 and the second sensing segment 321 can be connected and transmit the liquid inlet signal only when the liquid level in the liquid inlet detection sensor is higher than a predetermined threshold, thereby avoiding abnormal conduction caused by the first sensing segment 311 and the second sensing segment 321 being too close to each other, and also improving the detection reliability of the liquid inlet detection sensor.

[0062] Optionally, the connector 22 further has at least two second electrical connection ends, the first probe 31 further includes a first electrical connection segment 312, the second probe 32 further includes a second electrical connection segment 322, the first electrical connection segment 312 is electrically connected to one of the second electrical connection ends, and the second electrical connection segment 322 is electrically connected to another of the second electrical connection ends.

[0063] Specifically, the second electrical connection end, that is, the input end of the connector 22, is electrically connected to the first probe 31 and the second probe 32 respectively, and can receive the liquid inlet signal transmitted by the first probe 31 and the second probe 32; the first electrical connection end 221, that is, the output end of the connector 22, can transmit the liquid inlet signal transmitted by the first probe 31 and the second probe 32 to the electrically connected device to be tested, so as to facilitate the activation of the waterproof function of the device to be tested.

[0064] Among them, according to the specific type of the selected connector 22, the second electrical connection end and the first electrical connection end 221 can be located on two opposite sides of the connector 22, or on two adjacent sides of the connector 22, so as to adapt to different connection scenarios.

[0065] like Figure 2As shown, the first electrical connection section 312 of the first probe 31 is connected to a second electrical connection end of the connector 22, and the second electrical connection section 322 of the second probe 32 is connected to another second electrical connection end of the connector 22, so that the liquid inlet signal transmission from the first probe 31 and the second probe 32 to the connector 22 can be realized. In addition, according to the actual connection, the connector 22 can also be designed or selected to have three, four or even more second electrical connection ends. When one second electrical connection end is abnormal, other second electrical connection ends can be selected, so as to avoid the risk of connection abnormality caused by single-point connection failure and improve the detection stability of the liquid inlet detection sensor.

[0066] Optionally, the connector 22 further has a circuit board, and the first electrical connection end 221 and the second electrical connection end are electrically connected via the circuit board.

[0067] Specifically, the circuit board is the core of the electrical connection inside the connector 22, which can provide a stable and reliable electrical signal transmission path between the first electrical connection end 221 and the second electrical connection end, and can also simplify the wiring design inside the connector 22, facilitating the miniaturization of the connector 22. The liquid inlet signal transmitted by the first probe 31 and the second probe 32 received from the second electrical connection end can be transmitted to the electrically connected detected device through the first electrical connection end 221. According to the actual layout, the circuit board can be a PCB (Printed Circuit Board), or an FPC (Flexible Printed Circuit board), etc.

[0068] In addition, in other embodiments, the connector 22 can be designed to also have a connecting harness, and the first electrical connection end 221 and the second electrical connection end are electrically connected through the connecting harness, so as to adapt to long-distance signal transmission requirements, thereby being able to adapt to different detection scenarios and detection requirements.

[0069] Optionally, the connector 22 includes a shell 222 and an anti-error section 223, the shell 222 is connected to the main body 1, the shell 222 has a through groove 2221, the through groove 2221 is connected to the through hole, the first electrical connection end 221 is located on the side of the shell 222 away from the through hole, the second electrical connection end is located on the side of the shell 222 close to the through hole, and the anti-error section 223 is arranged on the inner wall of the through groove 2221.

[0070] like Figure 2As shown, the housing 222 is used to form a match and connection with the mounting portion on the detected device. The housing 222, as the main structural part of the connector 22, is connected to the body 1 and plays a role in fixing and supporting the connector 22. The through groove 2221 in the housing 222 is connected to the through hole on the body 1, which can provide space for the first probe 31 and the second probe 32 to pass through and connect, thereby realizing the electrical connection between the first probe 31 and the second probe 32 and the connector 22.

[0071] The first electrical connection end 221 can be located on a side of the housing 222 away from the through hole, that is, the first electrical connection end 221 is located on the outside of the liquid inlet detection sensor, which can facilitate the first electrical connection end 221 to form an electrical connection with the detected device. The second electrical connection end is located on a side of the housing 222 close to the through hole, which can facilitate the first probe 31 and the second probe 32 to form an electrical connection with the second electrical connection end.

[0072] Furthermore, an anti-error section 223 may be designed on part of the inner wall of the shell 222, and the position or shape of the anti-error section 223 may be used as a guide for the installation of the liquid inlet detection sensor, thereby improving the installation efficiency and reducing the risk of installation misalignment.

[0073] Optionally, the first probe 31 further includes a first transition section 313 connected between the first sensing section 311 and the first electrical connection section 312 , and the second probe 32 further includes a second transition section 323 connected between the second sensing section 321 and the second electrical connection section 322 .

[0074] like Figure 2 As shown, on the one hand, the provision of the first transition section 313 can avoid direct contact between the first sensing section 311 and the first electrical connection section 312, thereby reducing the risk of abnormalities such as short circuits caused by the liquid directly flowing back to the first electrical connection section 312; on the other hand, the provision of the first transition section 313 also facilitates increasing the distance between the first sensing section 311 and the second sensing section 321, thereby avoiding abnormal conduction caused by the first sensing section 311 and the second sensing section 321 being too close to each other, and also improving the detection reliability of the liquid inlet detection sensor.

[0075] Similarly, the setting of the second transition section 323, on the one hand, can avoid direct contact between the second sensing section 321 and the second electrical connection section 322, thereby reducing the risk of abnormalities such as short circuits caused by the liquid directly flowing back to the second electrical connection section 322; on the other hand, it is also convenient to increase the distance between the second sensing section 321 and the first sensing section 311, thereby avoiding abnormal conduction caused by the second sensing section 321 and the first sensing section 311 being too close to each other, and also improving the detection reliability of the liquid inlet detection sensor.

[0076] Optionally, an angle is formed between the first transition section 313 and the first induction section 311 , and between the first transition section 313 and the first electrical connection section 312 ;

[0077] And / or, an angle is formed between the second transition section 323 and the second induction section 321 , and an angle is formed between the second transition section 323 and the second electrical connection section 322 .

[0078] like Figure 2 As shown, the first sensing segment 311 and the first electrical connection segment 312 can be arranged to be bent and connected to the first transition segment 313 respectively, and the second sensing segment 321 and the second electrical connection segment 322 can be arranged to be bent and connected to the second transition segment 323 respectively. The first sensing segment 311 and the first electrical connection segment 312 can also be arranged to be bent and connected to the first transition segment 313 respectively, and the second sensing segment 321 and the second electrical connection segment 322 can be bent and connected to the second transition segment 323 respectively. The transition segment can be used to increase the distance between the second sensing segment 321 and the first sensing segment 311, avoid abnormal conduction caused by the second sensing segment 321 and the first sensing segment 311 being too close to each other, and improve the detection reliability of the liquid inlet detection sensor.

[0079] The angle between the first sensing section 311 and the first transition section 313 and the angle between the first electrical connection section 312 and the first transition section 313 can be the same, so as to facilitate production and processing; the angle between the first sensing section 311 and the first transition section 313 and the angle between the first electrical connection section 312 and the first transition section 313 can also be different, so as to adapt to different structural requirements. Similarly, the angle between the second sensing section 321 and the second transition section 323 and the angle between the second electrical connection section 322 and the second transition section 323 can also be the same or different.

[0080] Optionally, the first probe 31 further includes a first blocking member 314, which is located at an end of the first sensing section 311 close to the first electrical connection section 312; the second probe 32 further includes a second blocking member 324, which is located at an end of the second sensing section 321 close to the second electrical connection section 322, and the first blocking member 314 and the second blocking member 324 are respectively used to block the inflow of liquid.

[0081] like Figure 2 As shown, the first blocking member 314 can block the liquid flowing therethrough to reduce the risk of abnormalities such as short circuits caused by the liquid directly flowing back to the first electrical connection section 312 , thereby ensuring the detection reliability of the first probe 31 .

[0082] Similarly, the second blocking member 324 can block the liquid flowing therethrough, so as to reduce the risk of abnormalities such as short circuits caused by the liquid directly flowing back to the second electrical connection section 322 , thereby ensuring the detection reliability of the second probe 32 .

[0083] Optionally, the first blocking member 314 is a convex structure, and the structure of the second blocking member 324 is the same as that of the first blocking member 314 .

[0084] Specifically, the first blocking member 314 may be a convex structure, that is, a convex protection is formed at the end of the first sensing section 311 close to the first electrical connection section 312, such as a single convex block or a protective net formed by multiple convex blocks, which can block the liquid flowing through. Moreover, by adjusting the convex height and / or convex range of the first blocking member 314, its blocking ability can be adjusted accordingly.

[0085] Moreover, the structure of the second blocking member 324 is the same as that of the first blocking member 314, that is, the second blocking member 324 is also a convex structure. The second blocking member 324 can be used to reduce the risk of abnormalities such as short circuits caused by the liquid directly flowing back to the second electrical connection section 322, and it is also convenient to replace the second blocking member 324 with the first blocking member 314, thereby reducing the production cost of the liquid inlet detection sensor.

[0086] Optionally, along the extension direction of the first probe 31 , the first probe 31 is in a Z-shaped structure.

[0087] like Figure 2 and Figure 3 As shown, the design of the Z-shaped structure is convenient for increasing the distance between the sensing section and the electrical connection section of the first probe 31, and can also reduce the risk of abnormalities such as short circuits caused by the liquid directly flowing back to the first electrical connection section 312, thereby improving the detection reliability of the first probe 31.

[0088] Similarly, the second probe 32 is arranged in a Z-shaped structure along the extension direction of the second probe 32, which is convenient for increasing the distance between the sensing section and the electrical connection section of the second probe 32, and can also reduce the risk of abnormalities such as short circuit caused by the liquid directly flowing back to the second electrical connection section 322, thereby improving the detection reliability of the second probe 32.

[0089] Moreover, the Z-shaped design of the first probe 31 and the second probe 32 makes the sensing part 3 formed by the first probe 31 and the second probe 32 present a Y-shaped structure, so that the electrical connection sections of the two probes are relatively close, which can facilitate the electrical connection between the two, and the sensing sections of the two probes are relatively far apart, which can avoid abnormal conduction caused by the second sensing section 321 and the first sensing section 311 being too close, and also improves the detection reliability of the liquid inlet detection sensor.

[0090] Optionally, the structure of the first probe 31 is the same as that of the second probe 32 , which can facilitate the interchangeable use of the first probe 31 and the second probe 32 , simplify the production difficulty, and reduce the production cost.

[0091] Optionally, the sensing portion 3 further includes a mounting seat 33 and a baffle 34, the mounting seat 33 is connected to the main body 1, the first probe 31 and the second probe 32 are located on a side of the mounting seat 33 away from the main body 1, and the baffle 34 is located on the mounting seat 33 and blocks the outside of the first probe 31 and the second probe 32.

[0092] like Figure 3 As shown, the mounting seat 33 is the base of the sensing part 3, which is connected to the body 1 and is used to achieve the connection and fixation of the sensing part 3. In addition, the mounting seat 33 also provides a receiving space, which is used to receive and set the first probe 31 and the second probe 32.

[0093] In addition, a baffle 34 is provided at the end of the mounting seat 33, and the baffle 34 can form a certain shielding for the first probe 31 and the second probe 32 on the inner side, thereby preventing the first probe 31 and the second probe 32 from being directly exposed to the detection environment, thereby reducing the risk of detection abnormalities caused by foreign matter adhering to the probes, and also improving the detection reliability of the liquid inlet detection sensor.

[0094] Optionally, along the height direction of the liquid inlet detection sensor, the baffle 34 has a structure that is low in the middle and high on both sides.

[0095] like Figure 3 As shown, the height direction of the liquid inlet detection sensor is also the extension direction of the connecting part 2-main body 1-sensing part 3. The baffle 34 is set to have a structure that is low in the middle and high on both sides, which can ensure that the baffle 34 forms a certain shielding for the first probe 31 and the second probe 32 on the inner side, avoiding the first probe 31 and the second probe 32 from being directly exposed to the detection environment, thereby reducing the risk of detection abnormalities caused by foreign matter adhering to the probes, while increasing the exposed area of ​​the shielded first probe 31 and the second probe 32, avoiding the self structure of the baffle 34 from hindering or interfering with the induction and conduction of the first probe 31 and the second probe 32, thereby improving the detection reliability of the liquid inlet detection sensor.

[0096] Optionally, along the height direction of the liquid inlet detection sensor, the mounting seat 33 is in a U-shaped structure, and the first probe 31 and the second probe 32 are respectively located on two opposite side walls of the U-shaped structure.

[0097] like Figure 1 and Figure 3As shown, the mounting seat 33 is provided with a U-shaped structure, and its U-shaped opening is away from the main body 1. The opposite side walls of the U-shaped structure can be used to increase the distance between the first probe 31 and the second probe 32, so as to ensure that the first probe 31 and the second probe 32 can be turned on and transmit the liquid inlet signal only when the liquid level in the liquid inlet detection sensor is higher than a predetermined threshold value, thereby avoiding abnormal conduction caused by the first probe 31 and the second probe 32 being too close to each other, and also improving the detection reliability of the liquid inlet detection sensor.

[0098] Optionally, the mounting seat 33 includes a recessed area and a main body area located on both sides of the recessed area, the recessed area is recessed toward the direction close to the main body 1, and one of the first probe 31 and the second probe 32 is located in the main body area on one side, and the other of the first probe 31 and the second probe 32 is located in the main body area on the other side.

[0099] like Figure 1 and Figure 3 As shown, the recessed area is set to be recessed in the direction close to the body 1 to form a recessed structure of the mounting seat 33. The first probe 31 and the second probe 32 are respectively located in the body area on both sides of the recessed area, so that the first probe 31 and the second probe 32 can be fixed by the body area, and the distance between the first probe 31 and the second probe 32 can be increased by the recessed area to ensure that the first probe 31 and the second probe 32 can be turned on and transmit the liquid inlet signal only when the liquid level in the liquid inlet detection sensor is higher than a predetermined threshold, avoiding abnormal conduction caused by the first probe 31 and the second probe 32 being too close.

[0100] Optionally, openings are respectively opened in the body area on both sides, the first probe 31 passes through the first opening 331 and is connected to the connecting part 2, the second probe 32 passes through the second opening 332 and is connected to the connecting part 2, and the first opening 331 and the second opening 332 are respectively filled with sealant.

[0101] like Figure 3 As shown, on the one hand, the opening of the first opening 331 and the second opening 332 can provide guidance for the connection and fixation of the first probe 31 and the second probe 32, thereby reducing the difficulty of production and assembly; on the other hand, by respectively applying sealant to the first opening 331 and the second opening 332, the fixation of the first probe 31 and the second probe 32 can be strengthened, and the connection can also be sealed to avoid the risk of abnormalities such as short circuit caused by liquid flowing back into the electrical connection section, thereby improving the detection reliability of the sensing part 3.

[0102] Optionally, the connecting portion 2 further comprises an assembly end 21, and the assembly end 21 is used for being detachably connected to the detected device. Figure 2As shown, the assembly end 21 can be a bushing, a buckle or other connecting device, which is used to form a mechanical connection with the mounting portion on the detected device. Moreover, setting it as a detachable connection can also improve the flexibility of the connection and facilitate maintenance and replacement.
