Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of temperature sensors, in particular to an NTC temperature sensor for a new energy vehicle thermal management system. BACKGROUND

[0002] NTC temperature sensors are widely used in the automotive industry, including coolant temperature sensors, intake air temperature sensors, and ambient temperature sensors. Automotive coolant temperature sensors typically use NTC thermistors as temperature sensing elements, so it can be considered that the automotive coolant temperature sensor is a specific application of NTC temperature sensors in the automotive field.

[0003] The main components of the automotive coolant temperature sensor include: a temperature sensing element responsible for sensing the temperature of the coolant, a housing for protecting the temperature sensing element from mechanical damage and environmental pollution, a sealing element (such as an O-ring or a sealing washer) to ensure the sealing between the sensor and the cooling system, a connector for electrical connection between the sensor and the engine control unit (ECU) or other electronic components, and a wire for transmitting the electrical signal generated by the temperature sensing element to the ECU. When installing the coolant temperature sensor, a screwdriver or other tool is usually used to tighten the sensor (without excessive force to avoid damaging the threads or sealing surface), and the sealing element is used to seal it. However, due to the constant vibration during vehicle use, long-term vibration can cause the sealing element to wear or deform, reducing its sealing performance. Vibration can also cause the connection between the sensor and the cooling system or other components to loosen, both of which can cause coolant to leak outside the sensor, causing electrical components to be damp or corroded, and thus affecting the accuracy and reliability of the sensor.

[0041] The locker 5 comprises a sliding rod 51 sliding with the inner wall of the sliding hole 21, the end of the sliding rod 51 close to the temperature sensing probe body 1 is fixedly connected with the inside of the inner lining block 42, the circumferential outer surface of the sliding rod 51 is fixedly connected with a piston plate 52 sealingly sliding with the inner wall of the sealing cavity 22, the end of the sliding rod 51 away from the inner lining block 42 is rotatably connected with a locking rod 53 threadedly connected with the threaded hole, and the screw rotation direction of the locking rod 53 is opposite to that of the threaded column 2.

[0042] The inner part of the sealing ring block 44 is nested with an elastic ring plate 441, the inner part of the ring block 41 is slidably connected with a pulling plate 413 rotatably connected with the inner part of the elastic ring plate 441, the side of the pulling plate 413 away from the elastic ring plate 441 is fixedly connected with a magnetic plate 414, and the side of the magnetic plate 414 close to the pulling plate 413 is provided with a micro spring 415 connected with the inner part of the ring block 41.

[0043] The circumferential outer surface of the temperature sensing probe body 1 is provided with a magnetic block 12 magnetically connected with the magnetic plate 414, and in the initial state, the magnetic plate 414 and the magnetic block 12 are in a mutual magnetic force attraction state, and the space surrounded by the sealing ring block 44 is smaller in diameter than the diameter of the ring-shaped baffle 43.

[0045] Reference Figures 1-10 Because of the vibration generated during the use of the automobile, the long-time vibration may cause the sealing element to be worn or deformed, thereby reducing the sealing performance, and the vibration may also cause the connection between the sensor and the cooling system or other components to be loose, both of which may cause the cooling liquid to leak outside the sensor, causing the electrical components to be damp or corroded, thereby affecting the accuracy and reliability of the sensor;

[0046] In order to overcome the above-mentioned defects, the present application designs a NTC temperature sensor for a new energy automobile thermal management system.

[0047] Conventional installation mode:

[0048] Ensure that the vehicle is in an off state and the engine has been cooled down, then align the temperature sensing probe body 1 with the threaded mounting hole in the cooling tank, then rotate the hexagonal head 20 (the side of the hexagonal head 20 close to the cooling tank is provided with a sealing washer) clockwise by using a screwdriver, the temperature sensing probe body 1 is inserted into the inside of the cooling tank, and the hexagonal head 20 is continuously rotated (without excessive force to avoid damaging the threads or the sealing surface), until the threaded column 2 is tightly locked with the threaded mounting hole of the cooling tank, and the outside sealing and locking of the NTC temperature sensor is completed.

[0049] Bidirectional sealing mode:

[0050] To further improve the sealing of the NTC temperature sensor of the present application, the inner seal 4 and the lock 5 are provided. It is emphasized that in the initial state, the ring-shaped block 41 on the inner seal 4 is driven by the elastic force of the strong spring 412 to slide the inner lining block 42 along the inner wall of the built-in groove 11 to the farthest position (at this time, the spacing between the ring-shaped baffle 43 and the outer end of the threaded column 2 is maximized), at the same time, the magnetic plate 414 is slid to the corresponding position of the magnetic block 12, and the magnetic plate 414 is driven by the magnetic force of the magnetic block 12 to slide the pull plate 413 along the inside of the ring-shaped block 41 to the center axis of the slide rod 51 in a short distance (the micro spring 415 is elastically deformed under pressure), until the magnetic plate 414 and the magnetic block 12 are attached together, and the magnetic plate 414 is provided with six groups in the present application, which are simultaneously slid in a short distance to the center axis of the slide rod 51, the elastic ring plate 441 is elastically deformed under uniform tension, driving the sealing ring block 44 to be elastically deformed, and the space surrounded by the sealing ring block 44 becomes smaller (the "space diameter" surrounded by the sealing ring block 44 is smaller than the diameter of the ring-shaped baffle 43), avoiding the interference between the sealing ring block 44 and the threaded mounting hole inside the cooling box during normal installation of the NTC temperature sensor, affecting the rapid insertion of the sealing ring block 44.

[0051] As can be seen from the above, when the inner seal 4 follows the temperature sensing probe body 1 into the inside of the cooling box, the outer sealing and locking of the NTC temperature sensor of the present application can be realized by rotating the hexagonal head 20. Then, the hexagonal head 20 is fixed by a screwdriver, and the locking rod 53 on the lock 5 is rotated counterclockwise by another screwdriver, driving the piston plate 52, the slide rod 51, the inner lining block 42 and the ring-shaped baffle 43 to move synchronously to the side of the connector 3, the ring-shaped block 41 slides along the circumferential outer surface of the temperature sensing probe body 1, driving the magnetic plate 414 to separate from the magnetic block 12, under the elastic force of the micro spring 415, the pull plate 413 and the magnetic plate 414 are quickly reset, cooperating with the elastic force of the elastic ring plate 441 and the sealing ring block 44 to realize the quick reset of the elastic ring plate 441 and the sealing ring block 44, and the circular space surrounded by the sealing ring block 44 after reset is larger than the diameter of the ring-shaped baffle 43. With the further rotation of the locking rod 53, the piston plate 52 is sealed and locked inside the sealing cavity 22, at the same time, the ring-shaped baffle 43 drives the sealing ring block 44 to tightly adhere to the threaded mounting hole inside the cooling box, realizing the inside sealing and locking of the NTC temperature sensor. As described above, the clockwise rotation of the hexagonal head 20 and the counterclockwise rotation of the locking rod 53 can realize the bidirectional sealing of the NTC temperature sensor.

[0052] The present application is provided with the inner seal 4 and the lock 5, which have the following advantages:

[0053] Advantage one: first, the hexagonal head 20 is rotated clockwise to drive the threaded column 2 to seal and lock the threaded mounting hole of the cooling box, and then the locking rod 53 is rotated counterclockwise (the locking rod 53 rotates around the outer end of the sliding rod 51), which generates an outward transverse pulling force on the sliding rod 51 and acts on the ring-shaped baffle 43. The reset sealing ring block 44 tightly fits on the threaded mounting hole inside the cooling box, and the two work together to realize the bidirectional sealing of the NTC temperature sensor.

[0054] Advantage two: since the screw rotation direction of the locking rod 53 is opposite to that of the threaded column 2, after the bidirectional sealing installation of the NTC temperature sensor, the connector 3 and the locking rod 53 are combined into a whole (both are locked by long threads) under the action of the sealing ring block 44. When external vibration force is transmitted to the connector 3, hexagonal head 20 and other components, the connector 3 has a reverse rotation tendency, and the locking rod 53 also has a reverse rotation tendency. Since the locking rod 53 has been sealed and locked to the sealing ring block 44 when it is initially locked, the locking rod 53 cannot be further rotated counterclockwise, thereby overcoming the reverse loosening of the connector 3. Similarly, the locking rod 53 will not be able to loosen clockwise.

[0055] Advantage three: the present application realizes the zooming change of the space range surrounded by the sealing ring block 44 through the cooperation of the magnetic plate 414 and the magnetic block 12. Specifically, initially, in order to facilitate the rapid passage of the sealing ring block 44 through the threaded mounting hole inside the cooling box, the sealing ring block 44 is in a uniform contraction state. When the sealing ring block 44 needs to seal the threaded mounting hole inside the cooling box, the sealing ring block 44 begins to reset, and the "large sealing ring block 44" tightly fits the outer end of the threaded mounting hole inside the cooling box.

[0056] The fourth advantage is that the elastic ring plate 441 is nested in the inside of the sealing ring block 44, and the center axis of the elastic ring plate 441 after resetting is coincident with the center axis of the sealing ring block 44, when the ring type baffle 43 acts on the sealing ring block 44 closely attached to the thread mounting hole inside the cooling box, the sealing ring block 44 is easy to be elastically deformed, which affects the overall sealing performance of the sealing ring block 44 (firstly, the space surrounded by the sealing ring block 44 after resetting is larger than the space surrounded by the ring type baffle 43, secondly, the sealing ring block 44 overflowing outside the ring type baffle 43 cannot provide stable force by the elastic ring plate 441). In this regard, the application further provides a T-shaped plate 442, and the elastic ring plate 441 and the T-shaped plate 442 are designed in an integrated forming mode, and the T-shaped plate 442 is vertically distributed on the circumferential outer surface of the elastic ring plate 441. Firstly, when the elastic ring plate 441 is elastically deformed, the T-shaped plate 442 does not interfere with the elastic deformation of the elastic ring plate 441, and secondly, the T-shaped plate 442 is parallel to the stress direction of the sealing ring block 44, and can provide sufficient supporting force for maintaining the stability of the sealing ring block 44, preventing the peripheral compression deformation of the sealing ring block 44, and affecting the sealing performance of the inside of the thread mounting hole.

[0057] The above examples are only used to illustrate the technical solutions of the present application, but not to limit it; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can be modified, or some technical features can be replaced by equivalents; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present application.
