Description

Technical Field

[0001] The present invention relates to the field of temperature detection, and further to a temperature detection device, wherein the temperature detection device is particularly suitable for vehicles. Background Art

[0002] With the development of science and technology, the automotive industry has experienced tremendous growth. More and more vehicles have entered people's daily lives, becoming an essential means of transportation and bringing great convenience to people's lives. People spend most of their time in vehicles, such as commuting to work and on road trips. Therefore, the quality of the vehicle's internal environment constantly affects people's user experience.

[0003] The temperature inside the car is a key factor affecting the experience of the people inside the car. Temperatures that are too high or too low will affect the riding experience of the people inside the car. Only when the temperature inside the car is within an appropriate range can the people inside the car have a better riding experience.

[0004] Furthermore, whether the vehicle driver drives the vehicle at a higher temperature or a lower temperature, it will affect the vehicle driver's mood. Especially when the vehicle driver is driving the vehicle at high speed, the slightest emotional fluctuation of the vehicle driver will cause great safety hazards, causing great safety hazards to the vehicle driver and the passengers inside the vehicle.

[0005] It is understandable that in order to control the temperature inside the vehicle within a suitable temperature range, temperature detection inside the vehicle is a necessary process, and only by accurately detecting the temperature inside the vehicle can the temperature inside the vehicle be accurately controlled within a suitable temperature range.

[0006] However, it should be noted that in the context of automotive air conditioning, the temperature inside the vehicle is measured via a forced ventilation system consisting of a ventilation motor and a temperature sensor. The ventilation motor, installed in the climate control unit, draws air from the vehicle interior and passes it through ventilation ducts to the temperature sensor.

[0007] The temperature sensor is thermally isolated from the circuit board and other controller components to prevent interference. Forced convection from the ventilation motor allows the temperature sensor to detect the temperature of incoming air from the vehicle interior. The ventilation motor generates considerable noise, and particulate matter in the air can enter and accumulate on the surface of the temperature sensor, affecting its accuracy.

[0008] Therefore, in order to improve the detection accuracy of the vehicle's internal temperature, the temperature detection device inside the vehicle needs to be improved. Summary of the Invention

[0047] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0048] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0049] It is understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0050] Reference Manual Figures 1 to 7, the temperature detection device 100 provided by the present invention is described. The temperature detection device 100 provided by the present invention is suitable for use in a vehicle to detect the temperature inside the vehicle. It should be noted that compared with traditional temperature detection devices, the temperature detection device 100 provided by the present invention can accurately detect the temperature inside the vehicle, so that people in the vehicle can accurately know the temperature information inside the vehicle, and at the same time, provide temperature data support for accurately controlling the temperature inside the vehicle.

[0051] It should be pointed out that in this preferred embodiment, the temperature detection device 100 is introduced as being applied to a vehicle. Those skilled in the art should understand that, in other preferred embodiments of the present invention, the temperature detection device 100 can also be applied to other application scenarios.

[0052] Specifically, the temperature detection device 100 includes a housing 10, a circuit board 20, a first temperature detection member 30 and a second temperature detection member 40, wherein the housing 10 has a receiving chamber 11, the circuit board 20 is arranged in the receiving chamber 11, the first temperature detection member 30 and the second temperature detection member 40 are respectively electrically connected to the circuit board 20, wherein the first temperature detection member 30 and the second temperature detection member 40 are respectively suitable for detecting temperature data. The first temperature detection member 30 is used to detect the temperature of the external environment, and the second temperature detection member 40 is used to detect the temperature of the first temperature detection member 30. Based on the temperature value detected by the first temperature detection member 30 and the temperature value detected by the second temperature detection member 40, the actual temperature value of the environment to be measured can be calculated. The circuit board 20 is suitable for being electrically connected to an external circuit to provide electrical energy for the first temperature detection member 30 and the second temperature detection member 40. On the other hand, through the circuit board 20, the temperature data detected by the first temperature detection member 30 and the second temperature detection member 40 are transmitted to the outside world.

[0053] It should be pointed out that when the temperature detection device 100 provided by the present invention is installed in a vehicle 200, the heat inside the vehicle 200 passes through the first temperature detection component 30 and the second temperature detection component 40 in sequence, and the temperature inside the vehicle 200 is calculated based on the temperatures detected by the first temperature detection component 30 and the second temperature detection component 40.

[0054] Specifically, the first temperature detecting member 30 and the second temperature detecting member 40 are respectively provided on the circuit board 20, and the circuit board 20 is configured to support the first temperature detecting member 30 and the second temperature detecting member 40. In other preferred embodiments of the present invention, the first temperature detecting member 30 and the second temperature detecting member 40 can also be provided on the housing 10, and the housing 10 provides support for the first temperature detecting member 30 and / or the second temperature detecting member 40. In other preferred embodiments of the present invention, the first temperature detecting member 30 and the second temperature detecting member 40 can also be provided on other components of the temperature detecting device 100. As long as the purpose of the present invention can be achieved, the specific location of the first temperature detecting member 30 and the second temperature detecting member 40 should not constitute a limitation to the present invention.

[0055] Furthermore, there is a preset distance between the first temperature detecting member 30 and the second temperature detecting member 40 so that the temperatures detected by the first temperature detecting member 30 and the second temperature detecting member 40 have a certain difference, so as to facilitate calculation of the actual temperature inside the vehicle 200.

[0056] Specifically, the heat inside the vehicle 200 is first transferred through the first temperature detection component 30, and a temperature value T1 is detected by the first temperature detection component 30. Then, the heat is transferred from the first temperature detection component 30 to the second temperature detection component 40 along the direction of the first temperature detection component 30 toward the second temperature detection component 40, and a temperature value T2 is detected by the second temperature detection component 40. Then, the actual temperature value T of the interior space of the vehicle 200 is calculated based on the temperature values T1 and T2.

[0057] Preferably, the first temperature detecting member 30 and the second temperature detecting member 40 are temperature sensors respectively.

[0058] Furthermore, at least a portion of the detection area of the first temperature detection component 30 is not blocked by the shell 10, and at least a portion of the detection area of the first temperature detection component 30 can directly contact the external environment to reduce the loss in the heat transfer process and improve the accuracy of the temperature detection results inside the vehicle.

[0059] Specifically, the housing 10 has a detection through hole 12, the shape and size of which are adapted to the shape and size of the first temperature detection member 30, and the first temperature detection member 30 is disposed within the detection through hole 12. On the one hand, through the detection through hole 12, at least a portion of the detection area of the first temperature detection member 30 can be in contact with the external environment, thereby improving the accuracy of the temperature detection result. On the other hand, when the first temperature detection member 30 is disposed within the detection through hole 12 of the housing 10, the housing 10 can provide support for the first temperature detection member 30, thereby improving the stability of the first temperature detection member 30.

[0060] It should be understood by those skilled in the art that the first temperature detection component 30 can be in direct contact with the external environment through the detection hole 12. When the temperature detection device 100 provided by the present invention is arranged in the vehicle 200, the first temperature detection component 30 can be in direct contact with the internal space environment of the vehicle 200, thereby reducing the loss during heat transfer.

[0061] The second temperature detecting component 40 is located in the accommodating cavity 11 of the shell 10. After the heat passes through the first temperature detecting component 30 and is detected by the first temperature detecting component 30 to obtain the temperature value T1, the heat continues to be transferred toward the second temperature detecting component 40, and the second temperature detecting component 40 performs a second temperature detection to obtain the temperature value T2.

[0062] It will be understood by those skilled in the art that, in the process of heat being transferred from the interior space of the vehicle 200 to the first temperature detecting member 30 and being detected by the first temperature detecting member 30, a certain amount of heat loss will occur, that is, the temperature value detected by the first temperature detecting member 30 is not the actual temperature value of the interior space of the vehicle 200. In the process of heat being transferred from the first temperature detecting member 30 to the second temperature detecting member 40, a certain amount of heat loss will also occur, that is, the temperature value T2 obtained by the second temperature detecting member 40 is less than the temperature value T1 obtained by the first temperature detecting member 30. The present invention calculates the actual temperature value of the interior space of the vehicle 200 by using the temperature value T1, the temperature value T2, the heat loss coefficient of heat transferred from the outside to the first temperature detecting member 30, and the heat loss coefficient of heat transferred from the first temperature detecting member 30 to the second temperature detecting member 40.

[0063] It should also be noted that during the temperature detection process of the second temperature detection member 40, the second temperature detection member 40 is only required to detect the temperature of the heat transferred from the first temperature detection member 30 to the second temperature detection member 40. Therefore, it is necessary to avoid interference from external environmental heat during the temperature detection process of the second temperature detection member 40. Therefore, in this preferred embodiment, the second temperature detection member 40 is disposed within the accommodating cavity 11 of the housing 10 to reduce the impact of heat outside the housing 10 on the detection results of the second temperature detection member 40.

[0064] Reference Manual Figure 3 and attached Figure 4 Furthermore, the temperature detection device 100 further includes a heat conductor 50, which is configured to guide heat from the first temperature detection component 30 to the second temperature detection component 40, while reducing the external heat transferred to the second temperature detection component 40, thereby reducing the interference of external heat on the temperature detection of the second temperature detection component 40.

[0065] Specifically, the heat conducting member 50 covers the first temperature detecting member 30 and the second temperature detecting member 40, respectively, to transfer heat from the first temperature detecting member 30 to the second temperature detecting member 40. Furthermore, the heat conducting member 50 covers a portion of the first temperature detecting member 30, so that at least a portion of the detection area of the first temperature detecting member 30 can directly contact the external environment. The heat conducting member 50 covers the entire detection area of the second temperature detecting member 40, so as to prevent external heat from affecting the temperature detection result of the second temperature detecting member 40.

[0066] Reference Manual Figure 3 and Figure 4Furthermore, the heat-conducting member 50 further includes a first heat-conducting element 51 and a second heat-conducting element 52, and a wrapping cavity 53 formed between the first heat-conducting element 51 and the second heat-conducting element 52. The first heat-conducting element 51 and the second heat-conducting element 52 of the heat-conducting member 50 are respectively covered on the front and back sides of the circuit board 20. It should be pointed out that in this preferred embodiment, the side of the circuit board 20 on which the second temperature detecting member 40 is provided is defined as the front side, and the side opposite to the side on which the second temperature detecting member 40 is provided is defined as the back side. Preferably, the first heat-conducting element 51 is covered on the front side of the circuit board 20, and the second heat-conducting element 52 is provided on the back side of the circuit board 20, so that the second temperature detecting member 40 can be wrapped between the first heat-conducting element 51 and the circuit board 20, thereby improving the efficiency of heat transfer from the first temperature detecting member 30 to the second temperature detecting member 40, and avoiding external heat from interfering with the temperature detection of the second temperature detecting member 40.

[0067] Furthermore, the circuit board 20 further has a detection portion 21 and a connection portion 22. The first temperature detection member 30 and the second temperature detection member 40 are respectively electrically connected to the detection portion 21 of the circuit board 20. The connection portion 22 of the circuit board 20 is adapted to be electrically connected to an external circuit for providing power to the first temperature detection member 30 and the second temperature detection member 40 and, on the other hand, for transmitting detection data of the first temperature detection member 30 and the second temperature detection member 40 to the outside world.

[0068] The first heat conducting element 51 and the second heat conducting element 52 of the heat conducting member 50 are respectively covered on the front and back surfaces of the detection portion 21 of the circuit board 20 to wrap the first temperature detecting member 30 and the second temperature detecting member 40 .

[0069] Specifically, the first temperature sensing member 30 is disposed at an end of the sensing portion 21 away from the connecting portion 22, and the second temperature sensing member 40 is disposed at an end of the sensing portion 21 adjacent to the connecting portion 22. When the first heat-conducting element 51 and the second heat-conducting element 52 of the heat-conducting member 50 are respectively disposed on the front and back sides of the sensing portion 21 of the circuit board 20, at least a portion of the sensing area of the first temperature sensing member 30 is not blocked, thereby allowing direct contact with the external environment. The second temperature sensing member 40 is blocked by the first heat-conducting element 51 of the heat-conducting member 50, thereby preventing external heat from being transferred to the second temperature sensing member 40 and interfering with the temperature sensing by the second temperature sensing member 40.

[0070] Reference Manual Figure 3 and Figure 4The heat-conducting member 50 further includes a connecting element 54, which is configured to connect the first heat-conducting element 51 and the second heat-conducting element 52. Specifically, the first heat-conducting element 51 and the second heat-conducting element 52 are aligned with each other, and the shapes and sizes of the first heat-conducting element 51 and the second heat-conducting element 52 are adapted to each other. The corresponding ends of the first heat-conducting element 51 and the second heat-conducting element 52 are respectively connected to the connecting element 54. The connecting element 54 is used to connect and support the first heat-conducting element 51 and the second heat-conducting element 52, so that the wrapping cavity 53 is formed between the first heat-conducting element 51 and the second heat-conducting element 52.

[0071] The connecting element 54 further has a mounting channel 540, which communicates with the wrapping cavity 53. Preferably, in this preferred embodiment, the connecting element 54 is annular, and the mounting channel 540 is a circular channel. Those skilled in the art will appreciate that in other preferred embodiments of the present invention, the connecting element 54 and the mounting channel 540 may have other shapes, and the specific shapes of the connecting element 54 and the mounting channel 540 should not constitute a limitation to the present invention as long as the objectives of the present invention are achieved.

[0072] The first temperature detection component 30 is arranged in the installation channel 540, and at least a portion of the detection area of the first temperature detection component 30 corresponds to the opening on one side of the installation channel 540 away from the wrapping cavity 53, so that at least a portion of the detection area of the first temperature detection component 30 can directly contact the external environment.

[0073] Preferably, the shape and size of the first temperature detection component 30 are adapted to the shape and size of the mounting channel 540. When the first temperature detection component 30 is arranged in the mounting channel 540, the first temperature detection component 30 contacts the inner wall of the mounting channel 540, and the inner wall of the mounting channel 540 can provide support and stability for the first temperature detection component 30.

[0074] Furthermore, the connecting element 54 of the thermal conductor 50 is located within the detection through-hole 12 of the housing 10. The shape and size of the connecting element 54 are adapted to those of the detection through-hole 12. The outer wall of the connecting element 54 contacts the inner wall of the detection through-hole 12, and the inner wall of the detection through-hole 12 can provide support and stability for the connecting element 54 of the thermal conductor 50. Furthermore, the thermal conductor 50 extends through the detection through-hole 12 to the outside of the housing 10, so that at least a portion of the detection area of the first temperature detection element 30 can be in contact with the external environment.

[0075] The first heat-conducting element 51 has a first fixing portion 511 at one end away from the connecting element 54, and the second heat-conducting element 52 has a second fixing portion 521 at one end away from the connecting element 54. The first fixing portion 511 of the first heat-conducting element 51 and the second fixing portion 521 of the second heat-conducting element 52 correspond in position, and the first fixing portion 511 and the second fixing portion 521 correspond in shape and size. The first fixing portion 511 of the first heat-conducting element 51 and the second fixing portion 521 of the second heat-conducting element 52 are suitable for being connected to fix the first heat-conducting element 51 and the second heat-conducting element 52 to the front and back sides of the connecting portion 22 of the circuit board 20, thereby increasing the stability of the combination of the first heat-conducting element 51 and the second heat-conducting element 52 with the connecting portion 22 of the circuit board 20.

[0076] Specifically, the end of the first heat-conducting element 51 away from the connecting element 54 extends outward to form the first fixing portion 511. Preferably, the end of the first heat-conducting element 51 away from the connecting element 54 extends symmetrically to both sides to form the first fixing portion 511. The end of the second heat-conducting element 52 away from the connecting element 54 extends outward to form the second fixing portion 521. Preferably, the end of the second heat-conducting element away from the connecting element 54 extends symmetrically to both sides to form the second fixing portion 521.

[0077] The heat conducting member 50 further includes a set of fixing elements 55, which are configured to connect the first fixing portion 511 of the first heat conducting element 51 and the second fixing portion 521 of the second heat conducting element 52, so as to fix the first heat conducting element 51 and the second heat conducting element 52 to the detection portion 21 of the circuit board 20.

[0078] Specifically, the fixing element 55 further includes two fixing rods 551, one end of each fixing rod 551 is connected to the first fixing portion 511 of the first heat-conducting element 51, and the other end is connected to the second fixing portion 521 of the second heat-conducting element 52, and a certain distance is maintained between the two fixing rods 551 so as to fix the first fixing portion 511 of the first heat-conducting element 51 and the second fixing portion 521 of the second heat-conducting element 52 to the connecting portion 22 of the circuit board 20.

[0079] Furthermore, the circuit board 20 further has a group of fixing holes 23, which are configured to cooperate with the fixing element 55 to fix the first fixing portion 511 of the first heat-conducting element 51 and the second fixing portion 521 of the second heat-conducting element 52 to the detection portion 21 of the circuit board 20.

[0080] Specifically, there are two fixing holes 23 , and there is a preset distance between the two fixing holes 23 . That is, the two fixing holes 23 are formed in the detection portion 21 of the circuit board 20 at a preset distance.

[0081] Furthermore, the shape and size of the fixing holes 23 are adapted to the shape and size of the fixing rods 551, and one fixing rod 551 is disposed in each fixing hole 23. In other words, the fixing rods 551 pass through the fixing holes 23, and the ends of the fixing rods 551 are respectively connected to the first fixing portion 511 of the first heat-conducting element 51 and the second fixing portion 521 of the second heat-conducting element 52, so as to connect the first fixing portion 511 and the second fixing portion 521 to the front and back sides of the connecting portion 22 of the circuit board 20.

[0082] The circuit board 20 further has an extension portion 24. The position of the extension portion 24 corresponds to the shape and size of the first fixing portion 511 of the first heat-conducting element 51 and the second fixing portion 521 of the second heat-conducting element 52, and is used to support the first fixing portion 51 of the first heat-conducting element 51 and the second fixing portion 521 of the second heat-conducting element 52. Specifically, the extension portion 24 is formed by extending toward both sides of the end of the detection portion 21 of the circuit board 20 that is close to the connecting portion 22.

[0083] Preferably, the fixing hole 23 of the circuit board 20 is formed in the extension portion 24 of the circuit board 20, so that the first fixing portion 511 of the first heat-conducting element 51 and the second fixing portion 521 of the second heat-conducting element 52 correspond to each other, thereby facilitating the fixing of the first fixing portion 511 of the first heat-conducting element 51 and the second fixing portion 521 of the second heat-conducting element 52 to the detection portion 21 of the circuit board 20. It should be understood by those skilled in the art that, in other preferred embodiments of the present invention, the fixing hole 23 of the circuit board 20 can also be formed in other locations of the circuit board 20, such as the detection portion 21, the junction between the detection portion 21 and the extension portion 24, etc.

[0084] Preferably, the heat conducting member 50 is made of PA glue.
