Abstract
The invention relates to a temperature sensor for vehicles, belonging to the vehicle used temperature sensor field. The temperature sensor comprises a temperature sensing element, a shell body and a lead wire. The temperature sensing element is installed in the shell body, the position of the temperature sensing element is close to the top of the shell body, and one end of the lead wire extends into the shell body to be connected with the temperature sensing element. At least a temperature probing hole is formed at the top of the shell body, the temperature sensing element is a digital element, digital signals are transmitted through lead wires, and the detection precision is improved. In addition, the adoption of a connected facilitates the connection of the lead wires. Therefore, a drive can know the temperature of a heat interchanger and the actual working condition of the heat interchanger in real time.
Description
Technical field
The present invention relates to a kind of sensor, relate in particular to a kind of temperature sensor for vehicle that is used for vehicle, belong to the temperature survey field.
Background technology
Existing temperature sensor for vehicle, all adopt the transition transmission medium of housing as temperature, that is to say that the temperature that needs shilling housing to accept actuating medium just can make temperature-sensing element that temperature is detected in collecting temperature, therefore there are a delay and distortion stage inevitably, are unfavorable for the timely reflection of data.The operation of escort vehicle simultaneously, owing to the specific heat between housing and the temperature-sensing element there are differences, and the temperature of housing sometimes can cause temperature detection error to occur greater than the temperature at tested position.Moreover, when existing temperature sensor for vehicle is analog signal sensors, a conductor interface only is set carries out the transmission of signal, when temperature sensor faces a plurality of request of external instrument, that be easy to occur data read, transmission and have some setbacks, be unfavorable for timely processing to temperature data.
Summary of the invention
The objective of the invention is to overcome the above problem that prior art exists, temperature sensor for vehicle is provided.
Purpose of the present invention realizes by following technical solution:
Temperature sensor for vehicle, comprise temperature-sensing element, housing, lead, temperature-sensing element is installed in enclosure interior, its residing position is near the top of housing, one end of lead stretches in the housing and is connected with temperature-sensing element, is provided with the embedding thing between described housing and the lead, wherein: offer a temperature detection hole at least on the housing top, and temperature-sensing element is digital element, by the lead transmission of digital signals.
Purpose of the present invention also can further realize by following technical measures:
Above-mentioned temperature sensor for vehicle wherein, is provided with heat-conducting layer between described temperature-sensing element and the housing.
Further, above-mentioned temperature sensor for vehicle, wherein, described housing periphery is provided with heat-barrier material.
The outstanding substantive distinguishing features and the obvious improvement of technical solution of the present invention is mainly reflected in:
By adopting the design in temperature detection hole, can allow temperature-sensing element directly contact actuating medium, directly detected temperatures avoids adopting housing as the existing delayed phase of transition medium in the past, also further improve the precision that detects, and adopted connector to be convenient to the connection of lead.Thus, can allow the driver know the temperature of heat interchanger in real time, understand the practical working situation of heat interchanger.
Purpose of the present invention, advantage and characteristics will illustrate by the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.

Embodiment
Temperature sensor for vehicle as shown in Figure 1 and Figure 2, comprise lead 7, housing 4, temperature-sensing element 1, temperature-sensing element 1 is installed in housing 4 inside, its residing position is near the top of housing 4, one end of lead 7 stretches in the housing 4 and is connected with temperature-sensing element 1, is provided with embedding thing 6 between described housing 4 and the lead 7, and its difference with the prior art part is: offer a temperature detection hole 9 at least on housing 4 tops, and temperature-sensing element 1 is digital element, by lead 7 transmission of digital signals.Because the present invention adopted digital sensor, can directly export digital signal, and can be a plurality of system and use, therefore be provided with and patch device at the other end of lead 7, be convenient to connection.Because temperature-sensing element 1 is inserted behind housing 4 tops and might there be certain space in 4 of housings, therefore between temperature-sensing element 1 and housing 4, be provided with and lead the warm glue of leading of temperature and bonding effect, the part of overflowing allows to be present in the heat-conducting layer 2, when making temperature-sensing element 1 be fixed on housing 4 tops well, make housing 4 in the heat conduction in time simultaneously of being heated to temperature-sensing element, can also prevent that foreign matter such as water etc. from entering housing 4 by temperature detection hole 9 and causing data transmission fault or short circuit.Working environment further combined with temperature sensor for vehicle; it is under the higher temperature environment; for sensor self being played a protective effect, just the present invention's one preferred implementation is set out, and is provided with the heat-barrier material 3 that epoxy resin is principal ingredient in housing 4 peripheries.Make sensor self not influenced by the thermal conduction characteristic of housing 4 thus, keep duty preferably.
And, can in car body, carry out good stationkeeping in order to make temperature sensor for vehicle, periphery, described housing 4 top is the sexangle helicitic texture.Like this, can by with existing vehicle in components and parts carry out screw thread coupling, with the temperature sensor for vehicle installing and locating.In addition, on lead 7, be provided with insulating sleeve 5, guarantee that the data transmission of lead is interference-free, also just further guaranteed the accuracy of data.
In conjunction with actual test result, from being beneficial to the temperature-sensitive angle of temperature-sensing element 1, described temperature detection hole 9 can be for circular or other shape, so that actuating medium fully has enough contacting with temperature-sensing element 1.
The course of work of the present invention is roughly as follows: by the temperature detection hole 9 that housing 4 tops are offered, temperature-sensing element 1 can directly contact actuating medium begin to detect in the vehicle actuating medium in the heat interchanger temperature.Subsequently, detected data rely on lead 7 to transfer to digital form and patch device, handle thereby patch the instrument that device connects via pin 8 inputs.
This shows, the present invention adopts the design in temperature detection hole 9, can allow the temperature of temperature-sensing element 1 direct testing medium, avoids adopting housing 4 as the existing delayed phase of medium in the past, also further improve the precision that detects, and adopted connector to be convenient to the connection of lead 7.Can allow the driver know the temperature of heat interchanger in real time, understand the practical working situation of heat interchanger.
Certainly, more than only be concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.In addition to the implementation, the present invention can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the present invention's scope required for protection.
