Description

Technical Field

[0001] This utility model relates to the field of automotive parts installation technology, specifically a temperature sensor installation structure. Background Technology

[0002] The temperature sensor on the car's center console / control panel is mainly used for the automatic air conditioning system. It is usually located on the center console near the windshield, and in some models it may be installed below the instrument panel or near the air conditioning vents.

[0003] The automatic air conditioning system uses this temperature sensor to monitor the interior temperature in real time and feeds the data back to the air conditioning control unit. The control unit then automatically adjusts the cooling or heating intensity, fan speed, and airflow mode of the air conditioning system based on the difference between the set temperature and the actual temperature, so that the interior temperature can quickly reach and be maintained within the set comfortable range.

[0004] The temperature around the center console of a car can fluctuate drastically under different climatic conditions and usage scenarios. For example, in the hot summer, the temperature of the center console can reach 60-70°C after the vehicle has been exposed to the sun, while in the cold winter, the temperature may drop to minus ten degrees Celsius or even lower. This significant temperature change can affect the performance of the internal components of the sensor, leading to a decrease in its measurement accuracy and inaccurate temperature readings. Traditional installation methods use adhesive bonding, which is susceptible to temperature variations, increasing instability during installation. Furthermore, adhesive bonding is not sufficiently stable. Therefore, this application provides a temperature sensor mounting structure. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this utility model provides a temperature sensor mounting structure that solves the problems of increased instability during the installation process due to temperature variations and the inherent instability of the bonding method itself when using traditional adhesive bonding to install temperature sensors.

[0006] The temperature sensor mounting structure of this utility model includes a decorative plate for support, and a decorative shell is provided on one side of the decorative plate. The decorative shell and the decorative plate are fixed together by a through-joint. The decorative housing includes a housing, a support frame is mounted on the top of the housing, and a snap-fit ​​hole is provided on the housing, at which a sensor is installed; The sensor includes a body, a cable is provided on one side of the body, and the body is mounted on the support frame to keep the body fixed. The support frame includes a frame body, and the top of the frame body is provided with two symmetrically arranged inner side clips. An abutment block is provided on the side of the two inner side clips that are close to each other. The abutment block is engaged with the outer side of the body body to fix the sensor.

[0007] As a further improvement of this utility model, the top of the frame is provided with an outer retaining strip and an auxiliary strip on one side of the inner retaining strip to restrict the sensor body, and a positioning protrusion is provided on the other side of the inner retaining strip to position the sensor body when it is engaged.

[0008] As a further improvement of this utility model, the frame is provided with a through hole between the two inner side strips, and the through hole is adapted to fit the sensor body.

[0009] As a further improvement of this utility model, two upward-facing grooves are provided at the bottom of the frame, and adhesive tape is installed in the grooves, with one side of the adhesive tape flush with the bottom of the frame.

[0010] As a further improvement of this utility model, the bottom of the adhesive is bonded to the bottom of the housing and is located between the two card blocks.

[0011] As a further improvement of this utility model, the cable is located on one side of the main body and extends to the bottom of the decorative shell at a preset angle. The cable is located between two outer clips for fixing the cable.

[0012] As a further improvement of this utility model, the surface of the decorative panel is provided with through holes adapted to the sensor for fixing the support frame.

[0013] As a further improvement of this utility model, the top of the housing is provided with two symmetrically arranged locking blocks, and the support frame has locking slots on both sides, which are matched with the locking blocks on the decorative outer shell.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model uses inner locking strips, abutment blocks, outer locking strips, auxiliary strips, and positioning protrusions on the support frame to perform multi-directional locking and positioning of the sensor body, preventing the sensor from moving in the horizontal and vertical directions. At the same time, the frame and the decorative shell are matched by locking blocks and slots, which further enhances the stability of the overall structure. Moreover, the adhesive installed in the groove at the bottom of the frame is tightly bonded to the shell of the decorative shell, and the auxiliary connecting piece firmly fixes the frame to the shell, making up for the possible loosening problem of the connecting piece. Meanwhile, the through holes on the trim panel that are compatible with the sensor serve to position the support frame and restrict its horizontal movement, ensuring that the entire mounting structure is accurately positioned during vehicle operation. Compared to traditional adhesive mounting methods, this snap-fit ​​and multi-structure fixing method is less affected by temperature changes. Even if the temperature around the center console changes drastically, the mounting structure can still remain stable and will not become unstable due to temperature, unlike adhesive methods. This ensures the accuracy of sensor measurements and is also relatively quick to install. Attached Figure Description

However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0018] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 The temperature sensor 3, located on the car's center console / control panel, is used in the automatic air conditioning system. It monitors the interior temperature in real time and sends feedback to the air conditioning control unit. Based on the difference between the set temperature and the actual temperature, the control unit automatically adjusts the air conditioning's cooling / heating intensity, fan speed, and airflow mode to maintain a comfortable temperature inside the vehicle. It is typically installed on the center console near the windshield; in some models, it is located below the instrument panel or near the air vents.

[0020] The temperature around the center console of a car fluctuates drastically under different climates and usage scenarios. In summer, after being exposed to direct sunlight, it can reach 60-70°C, while in winter it may drop to below -10°C. Such significant temperature changes can affect the performance of the internal components of sensor 3, leading to decreased measurement accuracy and inaccurate readings.

[0021] Traditionally, temperature sensors 3 are installed using adhesive bonding. However, this method is susceptible to temperature variations, increasing instability during installation, and the bonding process itself is not stable enough. Therefore, a new installation structure for the temperature sensor 3 is proposed, comprising a supporting decorative panel 1, a decorative housing 2 on one side of the panel 1, and the decorative housing 2 being fixed to the panel 1 via a connecting piece. The decorative housing 2 includes a housing 25, a support frame 21 is mounted on the top of the housing 25, and a slot 23 is opened in the middle of the support frame 21 on the housing 25. A sensor 3 is installed at the slot 23. The sensor 3 includes a body 31, a cable 32 is provided on one side of the body 31, and the body 31 is mounted on a support frame 21 to keep the body 31 fixed. The support frame 21 includes a frame body 211. The top of the frame body 211 is provided with two symmetrically arranged inner side strips 213. An abutment block 214 is provided on the side of the two inner side strips 213 that are close to each other. The abutment block 214 is engaged with the outer side of the body 31 to fix the sensor 3.

[0022] To address the issues of instability caused by temperature variations and measurement accuracy being easily affected by temperature changes due to the traditional adhesive mounting method for the temperature sensor 3 on the center console, this embodiment proposes a new mounting structure for the temperature sensor 3. This structure mainly consists of a supporting decorative panel 1 and a decorative housing 2, which are fixed together by a connector. The temperature sensor 3 is installed inside the decorative housing 2.

[0023] The trim panel 1 has a decorative outer shell 2 on one side. The decorative outer shell 2 is fixed to the trim panel 1 by a through-hole connector, which can be a common connecting component such as a bolt or a clip. Taking a bolt as an example, corresponding mounting holes are pre-drilled on the trim panel 1 and the decorative outer shell 2. The bolt is passed through these mounting holes and then tightened with a nut, thereby achieving a firm connection between the decorative outer shell 2 and the trim panel 1. This connection method ensures that the entire installation structure will not easily loosen during vehicle operation, even if it is affected by factors such as vibration.

[0024] The decorative housing 2 includes a housing 25, which protects the internal components. A support frame 21 is mounted on the top of the housing 25, and the support frame 21 is used to mount the temperature sensor 3. A locking hole 23 is provided in the middle of the support frame 21 corresponding to the position of the housing 25. This locking hole 23 is a key position for mounting the sensor 3.

[0025] The sensor 3 includes a body 31 and a cable 32. The body 31 is a sensing component used to sense temperature and convert temperature signals into electrical signals. The cable 32 is used to transmit the temperature signals collected by the body 31 to the vehicle's air conditioning control unit.

[0026] The sensor body 31 is mounted on the support frame 21 for fixation. Specifically, the top of the frame 211 of the support frame 21 has two symmetrically arranged inner retaining strips 213. An abutment block 214 is provided on the side of the two inner retaining strips 213 that are close to each other. When installing the sensor body 31, the body 31 is placed between the two inner retaining strips 213, so that the abutment block 214 engages with the outer side of the body 31. This engagement method effectively fixes the sensor body 31 to the support frame 21, preventing it from shifting due to vibration or other reasons during vehicle operation, thus ensuring that the sensor 3 can accurately sense temperature.

[0027] Compared to traditional adhesive mounting methods, this snap-fit ​​structure, which mounts the sensor 3 onto the support bracket 21, offers superior stability. Even under drastic temperature fluctuations around the center console, the snap-fit ​​structure remains unaffected by temperature changes, unlike adhesive methods. Furthermore, this mounting structure better ensures the sensor 3 remains firmly in place, reducing measurement accuracy issues caused by installation instability. This allows the automatic climate control system to more accurately adjust the cabin temperature based on the temperature information from the sensor 3, providing a more comfortable environment for passengers.

[0028] Please see Figure 3 , Figure 4 , Figure 5 , Figure 6 as well as Figure 7 The top of the frame 211 is provided with an outer retaining strip 212 and an auxiliary strip 217 on one side of the inner retaining strip 213 to restrict the body 31 of the sensor 3. A positioning protrusion 215 is provided on the other side of the inner retaining strip 213 to position the sensor 3 body 31 when it is engaged.

[0029] The frame 211 has a through hole 216 between the two inner side clips 213, and the through hole 216 is adapted to fit the body 31 of the sensor 3.

[0030] The bottom of the frame 211 has two upward-facing grooves, and adhesive stickers 22 are installed in the grooves. One side of the adhesive stickers 22 is flush with the bottom of the frame 211.

[0031] In the automotive automatic air conditioning system, to more securely install the temperature sensor 3 on the center console, the top of the bracket 211 is structurally designed with further modifications. An outer retaining strip 212 and an auxiliary strip 217 are provided on one side of the inner retaining strip 213 at the top of the bracket 211. The outer retaining strip 212 and the auxiliary strip 217 work together to further restrict the sensor 3 body 31 from the side. When the sensor 3 body 31 is mounted on the support bracket 21, the outer retaining strip 212 and the auxiliary strip 217 prevent the body 31 from swaying or shifting horizontally. For example, when the car encounters bumpy roads and vibrates during driving, this restraining structure ensures that the sensor 3 body 31 remains in a stable mounting position, avoiding inaccurate measurements due to shaking.

[0032] A positioning protrusion 215 is provided on the top of the frame 211 on the other side of the inner retaining strip 213. When the sensor 3 body 31 is engaged, the positioning protrusion 215 plays a positioning role. When installing the sensor 3 body 31, the operator can accurately place the body 31 in the appropriate position according to the position of the positioning protrusion 215, so that the abutment block 214 can accurately engage with the outside of the body 31. The positioning protrusion 215 provides a reference point for the installation of the sensor 3 body 31, improving the accuracy and efficiency of the installation.

[0033] The frame 211 has a through hole 216 located between the two inner retaining strips 213. This through hole 216 is adapted to fit the body 31 of the sensor 3. The sensor 3 body 31 can pass through this through hole 216, which further enhances the connection stability between the body 31 and the frame 211. From a physical structure perspective, the through hole 216 is like a channel of a specific size, through which the sensor 3 body 31 can pass tightly. This also provides a certain degree of constraint on the sensor 3 body 31 in the vertical direction, reducing the possibility of the body 31 moving up and down. For example, during frequent starting and braking of a car, the sensor 3 body 31 is less likely to shift vertically due to inertia, ensuring that the sensor 3 can work continuously and stably.

[0034] The bottom of the frame 211 has two upward-facing grooves, and adhesive strips 22 are installed in the grooves. One side of the adhesive strips 22 is flush with the bottom of the frame 211. The function of the adhesive strips 22 is to further fix the frame 211 and make it better bonded to the housing 25 of the decorative outer shell 2. During installation, the adhesive strips 22 are first installed in the grooves. Since one side of the adhesive strips 22 is flush with the bottom of the frame 211, when the frame 211 is installed on the housing 25, the adhesive strips 22 can make uniform contact with the surface of the housing 25, providing a stable adhesive force. This adhesive force can assist the connecting parts (such as bolts, clips, etc.) to fix the frame 211 more firmly to the housing 25. During long-term use of automobiles, with the aging of parts and the influence of vibration, the connecting parts may become slightly loose. The adhesiveness of the adhesive strips 22 can compensate for this looseness to a certain extent, keep the relative position between the frame 211 and the housing 25 stable, and thus ensure the stability of the entire temperature sensor 3 mounting structure.

[0035] Please see Figure 4 , Figure 5 , Figure 6 , Figure 7 as well as Figure 8 The bottom of the adhesive 22 is bonded to the bottom of the housing 25 and is located between the two clips 24.

[0036] The cable 32 is located on one side of the main body 31 and extends to the bottom of the decorative shell 2 at a preset angle. The cable 32 is located between the two outer clips 212 for fixing the cable 32.

[0037] The surface of the decorative panel 1 has through holes adapted to the sensor 3 for fixing the support frame 21.

[0038] The top of the housing 25 is provided with two symmetrically arranged locking blocks 24, and the frame 211 of the support frame 21 has locking slots on both sides, which are engaged and matched with the locking blocks 24 on the decorative housing 2.

[0039] In the installation structure of the temperature sensor 3 in the car's center console, the bottom of the adhesive 22 is bonded to the bottom of the housing 25 of the decorative outer shell 2 and is located between two clips 24. The adhesive 22 plays a role in enhancing stability and buffering. For example, if 3M adhesive 22 is used, when the car vibrates during driving, the adhesive 22 can absorb some of the vibration energy, reducing the impact on the temperature sensor 3 and its installation structure. At the same time, it can further fix the relative position between the support bracket 21 and the housing 25. During installation, the adhesive 22 is first accurately placed between the two clips 24 to ensure that the bottom of the adhesive 22 is in full contact with the bottom of the housing 25, and then the bonding operation is performed to ensure that the adhesive 22 is firmly attached to the housing 25. In this way, even if it is affected by factors such as temperature changes and vehicle vibration during subsequent use, the adhesive 22 can maintain a stable connection state and maintain the stability of the entire installation structure.

[0040] The cable 32 of sensor 3 is located on one side of the main body 31 and extends to the bottom of the decorative housing 2 at a preset angle. The cable 32 is positioned between two outer retaining strips 212. This design is for securing the cable 32. During vehicle operation, vibrations and shaking may cause the cable 32 to shift or move, which could affect the transmission of the sensor 3 signal and potentially damage the cable 32 due to friction with other components. Placing the cable 32 between the two outer retaining strips 212 helps to restrict its movement. When installing the cable 32, it needs to be bent at a preset angle to ensure it extends smoothly to the bottom of the decorative housing 2 and is accurately positioned between the two outer retaining strips 212 to ensure effective securing.

[0041] The surface of the trim panel 1 has through holes adapted to the sensor 3. The main function of these through holes is to fix the support frame 21. During installation, when the trim housing 2 with the sensor 3 installed is assembled with the trim panel 1, the support frame 21 can be further connected and positioned with the trim panel 1 through these through holes. When the support frame 21 passes through the through holes, it can fit tightly with the trim panel 1, restricting the horizontal movement of the support frame 21, thereby improving the stability of the entire temperature sensor 3 mounting structure. For example, during vehicle operation, even if subjected to significant vibration, the support frame 21 is not prone to displacement due to the positioning effect of the through holes, ensuring the accurate installation position of the sensor 3.

[0042] The decorative housing 2 has two symmetrically arranged locking blocks 24 on its top, while the support frame 21 has locking slots on both sides of its frame 211. These slots engage with the locking blocks 24 on the decorative housing 2. This locking structure is a crucial step in the installation process, enabling the support frame 21 to be quickly and accurately fixed to the housing 25. During installation, the locking slots on both sides of the support frame 21 are aligned with the locking blocks 24 on the top of the housing 25, and then a certain amount of pressure is applied to make the locking blocks 24 engage with the slots. The tight fit between the locking blocks 24 and the slots prevents the support frame 21 from moving vertically and also resists horizontal forces to a certain extent. For example, when the vehicle experiences bumps, the locking structure between the locking blocks 24 and the slots ensures a stable connection between the support frame 21 and the housing 25, preventing easy separation and thus ensuring the overall stability and reliability of the temperature sensor 3's installation structure.

[0043] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
