Description

Technical Field

[0001] The utility model relates to the technical field of automobile thermostat temperature sensors, in particular to an automobile thermostat temperature sensor with a temperature conducting structure. Background Art

[0002] A thermostat is a valve that controls the flow of coolant. As an automatic temperature-regulating device, it typically contains a temperature-sensing component that opens and closes the flow of air, gas, or liquid by expanding or contracting. Its function is to automatically adjust the amount of water entering the radiator based on the coolant's temperature, varying the water's circulation range to regulate the cooling system's heat dissipation capacity and ensure the engine operates within the appropriate temperature range. The thermostat must be maintained in good working order; failure to do so can seriously affect engine operation. Opening the main thermostat valve too late can cause engine overheating; opening the main valve too early can prolong engine warm-up time and cause the engine temperature to drop too low. Thermostats typically require a temperature sensor to monitor the temperature of the fluid inside the thermostat in real time. The temperature sensor and connecting wires utilize a plug-and-socket connection.

[0003] For example, the authorization announcement number "CN209671063U" is named a thermostat, and the temperature sensor is used to connect the first electrical connection socket pair and the second electrical connection socket pair electrically connected to the sensing head at one end of the plug. When used in combination with the connecting plug, if the pin of a plug breaks during use and falls into and remains in the first electrical connection socket, the user only needs to replace the connecting plug with a size that is adapted to the second electrical connection socket, and insert the electrical connection pin of the connecting plug into the second electrical connection socket, avoiding the problem of directly replacing the temperature sensor and increasing the cost of equipment use and maintenance.

[0004] The above-mentioned and existing technologies have the following defects: the snap-on protrusion is inserted into and locked after passing through the hole of the sensor snap-on plate. Under the action of vibration, the snap-on protrusion is easy to slip out of the protruding notch, causing the coolant in the coolant flow cavity to flow out; at the same time, the connection between the electrical connection pin and the first electrical connection jack is easy to loosen, causing the temperature sensor to be unable to transmit temperature data.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Reference Figure 1-3 A car thermostat temperature sensor with a temperature-conducting structure includes a thermostat housing 1 and a temperature sensor 2.

Snap-fit ​​protrusions 6 adapted to the notches 5 are provided on both sides of the circumferential surface of the temperature sensor 2. A sealing baffle 7 adapted to the mounting groove 3 is slidably connected to the circumferential surface of the temperature sensor 2. The sealing baffle 7 plays a sealing role. A connecting block 8 is provided at the upper end of the temperature sensor 2, and a tightening spring 9 is provided between the lower surface of the connecting block 8 and the upper surface of the sealing baffle 7. The tightening spring 9 is sleeved on the temperature sensor 2. A connecting plug 10 is provided above the connecting block 8, and two pins 11 are provided on the lower surface of the connecting plug 10. Two slots 12 are provided on the upper surface of the connecting block 8. The pins 11 extend into the slots 12 and are electrically connected thereto. An anti-falling device is provided at the lower end of the connecting plug 10.

[0020] The anti-falling device includes an annular protrusion 13 and a connecting cover 14. The annular protrusion 13 is annularly arranged on the circumferential surface of the lower end of the connecting plug 10. The connecting cover 14 is sleeved on the connecting plug 10. The inner wall of the connecting cover 14 is threadedly connected to the surface of the connecting block 8.

[0021] The circumferential surface of the connecting plug 10 is provided with a limiting protrusion 15 in an annular manner, and the limiting protrusion 15 is arranged above the connecting cover 14. The limiting protrusion 15 can limit the connecting cover 14 to prevent the connecting cover 14 from sliding arbitrarily.

[0022] The circumferential surface of the connecting cover 14 is provided with a plurality of anti-skid grooves 16. The anti-skid grooves 16 are provided to prevent skidding.

[0023] A sealing gasket 17 is provided between the lower inner wall of the mounting groove 3 and the lower surface of the sealing baffle 7. The sealing gasket 17 provided plays a sealing role.

[0025] Working principle: When installing the temperature sensor 2, extend the snap-on protrusion 6 through the notch 5 into the coolant flow cavity, then rotate the temperature sensor 2, and through the elastic action of the pressing spring 9, press the sealing baffle 7 downward, so that the sealing baffle 7 is pressed against the lower inner wall of the installation groove 3. At the same time, through the driving action of the connecting block 8, the snap-on protrusion 6 is pressed against the thermostat housing 1. Under the action of vibration, the snap-on protrusion 6 is not easy to slide out of the notch 5, avoiding the coolant in the coolant flow cavity from flowing out; then insert the pin 11 into the slot 12, and by threading the connecting cover 14 with the connecting block 8, avoid loosening of the connection between the pin 11 and the slot 12, and ensure that the temperature sensor 2 can accurately transmit temperature data. Through the sensing head of the temperature sensor 2, the temperature data of the coolant in the coolant flow cavity can be transmitted to the computer terminal in the car through the connection between the pin 11 and the slot 12.
