Description

Technical Field

[0001] This utility model relates to the field of vehicle temperature detection technology, and in particular to a temperature sensor for new energy vehicles. Background Technology

[0002] With the rapid development of new energy vehicles, the stability of the in-vehicle air conditioning system directly affects the battery thermal management efficiency and passenger comfort. Among them, the air conditioning evaporator temperature sensor is a key component, and its installation accuracy and reliability are particularly important. It is usually located behind the passenger-side glove box. During installation, the glove box needs to be removed first, and then the probe of the temperature sensor is inserted into the evaporator. The rectangular body of the temperature sensor is located on the outer shell of the evaporator. The rectangular body is attached to the outer shell of the evaporator by the insertion of the probe. This method makes the rectangular body of the temperature sensor lack positioning. It may rotate during the driving process. At the same time, because the probe is long, if the insertion or removal direction is tilted during installation or removal, it is easy to cause the probe to bend or break, thereby increasing maintenance costs.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example 1 Reference Figures 1-4This is the first embodiment of the present invention, which provides a temperature sensor for new energy vehicles. The temperature sensor for new energy vehicles includes a main component 1, including a rectangular shell 11. The rectangular shell 11 mainly integrates a temperature sensing element, a signal processing circuit, and an electrical connection structure. A probe 12 is fixed on one side of the rectangular shell 11. This probe is a direct temperature measuring component that extends into the evaporator and transmits the temperature signal to the sensing element inside the sensor, thereby achieving real-time and accurate detection of the evaporator temperature. A wire 13 is fixed on one side of the rectangular shell 11, and a wiring port 14 is fixed on the other end of the wire 13. The wire 13 and the wiring port 14 are used for wiring the temperature sensor. The temperature sensor is located behind the passenger-side glove box of the car. Therefore, during installation, the glove box needs to be removed first to expose the evaporator. Then, the probe 12 is inserted into the evaporator through a small hole on the evaporator, and the rectangular shell 11 will fit against the outer wall of the evaporator. This is prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0025] Auxiliary component 2, located on one side of rectangular shell 11, includes a limiting block 21. A through groove 21-1 is provided in the limiting block 21. The size of the through groove 21-1 corresponds to the size of the rectangular shell 11. The limiting block 21 is fixed to the evaporator by adhesive. The limiting block 21 is also provided with a positioning hole 21-2 corresponding to the small hole of the evaporator. When fixing the limiting block 21, it is necessary to ensure that the positioning hole 21-2 is aligned with the small hole.

[0026] The auxiliary component 2 also includes a guide 22 located on the limiting block 21. The guide 22 is designed to ensure that the temperature sensor can be inserted and removed vertically when it is installed or removed, thereby preventing the probe 12 from bending.

[0027] The guide member 22 includes a fixed plate 221 fixed to the limiting block 21. A movable plate 222 is provided on one side of the fixed plate 221. The movable plate 222 can slide horizontally in a direction perpendicular to the end face of the limiting block 21. The distance between the fixed plate 221 and the movable plate 222 can be adjusted. When the two are close to each other, the guide member 22 is in a retracted state, which does not obstruct the installation of the glove box. A first rectangular block 223 is fixed on the movable plate 222, and a second rectangular block 224 is fixed on the rectangular shell 11. The second rectangular block 224 can fit against the first rectangular block 223. When installing the temperature sensor, first adjust the distance between the fixed plate 221 and the moving plate 222 to the maximum. Then push the rectangular shell 11 towards the evaporator and pass the probe 12 through the positioning hole 21-2 and the small hole in the evaporator. At this time, the second rectangular block 224 will first fit with the first rectangular block 223 and continue to push the first rectangular block 223 to move, thereby driving the moving plate 222 to gradually approach the fixed plate 221. The moving plate 222 can only move in the vertical direction of the evaporator shell, which can ensure that the probe 12 can be inserted and removed vertically relative to the evaporator.

[0028] Example 2 Reference Figure 3 and Figure 4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0029] Specifically, a first fixed shaft 225 is fixed on the fixed plate 221, and a first rotating plate 226 is connected to the first fixed shaft 225 by a bearing. A second fixed shaft 227 is fixed on the movable plate 222, and a second rotating plate 228 is connected to the second fixed shaft 227 by a bearing. Through the cooperation of the first rotating plate 226 and the second rotating plate 228, the movable plate 222 can move closer to or away from the fixed plate 221 along a straight line.

[0030] When the angle between the first rotating plate 226 and the second rotating plate 228 is large, the distance between the moving plate 222 and the fixed plate 221 is large, which is suitable for the process of installing the temperature sensor. When the angle between the first rotating plate 226 and the second rotating plate 228 is small, the distance between the moving plate 222 and the fixed plate 221 is small, which is suitable for the installation after the installation is completed. At this time, the guide 22 will not obstruct the installation of the glove box.

[0031] Specifically, the first rotating plate 226 and the second rotating plate 228 are hinged together.

[0032] Specifically, two first fixed shafts 225 are fixed on the fixed plate 221, which are arranged perpendicularly, and the number of first rotating plates 226 corresponds to them.

[0033] Specifically, two second fixed shafts 227 are fixed on the movable plate 222, which are arranged perpendicularly, and the number of second rotating plates 228 corresponds to this.

[0034] There are two guide members 22, which are symmetrically arranged on both sides of the rectangular shell 11 to ensure that they can guide the movement of the rectangular shell 11.

[0035] Example 3 Reference Figures 2-4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0036] Specifically, toothed blocks 229 are fixed on both the first rotating plate 226 and the second rotating plate 228.

[0037] Specifically, there are four tooth blocks 229, namely, first tooth block 229-1, second tooth block 229-2, third tooth block 229-3, and fourth tooth block 229-4. The first tooth block 229-1 is fixed on the upper first rotating plate 226 and can rotate around the first fixed axis 225. The second tooth block 229-2 is fixed on the lower first rotating plate 226 and the first tooth block 229-1 can engage with the second tooth block 229-2. The third tooth block 229-3 is fixed on the upper second rotating plate 228 and can rotate around the second fixed axis 227. The fourth tooth block 229-4 is fixed on the lower second rotating plate 228 and the third tooth block 229-3 can engage with the fourth tooth block 229-4. The arrangement of the four tooth blocks 229 plays the role of precise positioning and locking, stable power transmission, and resistance to lateral forces, thereby improving the stability of the moving plate 222 when moving relative to the fixed plate 221.

[0038] Specifically, the shape of the tooth block 229 is a half-face tooth.

[0039] Specifically, magnets 2210 are fixed on the fixed plate 221 and the movable plate 222. The temperature sensor is an NTC thermistor. The resistance of the semiconductor material decreases significantly with increasing temperature. By detecting the change in resistance, the temperature change is indirectly reflected. The setting of magnets 2210 will not affect the normal use of the sensor. The setting of magnets 2210 ensures that the movable plate 222 and the fixed plate 221 will not separate after they come close together. Even if there are bumps during the driving process, the movable plate 222 and the fixed plate 221 will not separate.

[0040] Specifically, magnets 2210 are fixed on the first rectangular block 223 and the second rectangular block 224. The magnets 2210 are set so that when the first rectangular block 223 and the second rectangular block 224 are close to each other, they will be tightly connected under the action of magnetic force. The bumps of the car will not cause them to separate. When it is necessary to separate them, simply pull the rectangular shell 11 to move away from the evaporator. The distance between the moving plate 222 and the fixed plate 221 will gradually increase. When they are at their limit position, if the rectangular shell 11 is pulled again, the moving plate 222 will not move, thereby separating the first rectangular block 223 and the second rectangular block 224.

[0041] When in use, first remove the glove box on the passenger side to expose the air conditioning evaporator. Then align the positioning hole 21-2 with the small hole on the evaporator. Fix the limiting block 21 to the outer shell of the evaporator by adhesive. Then maximize the gap between the fixing plate 221 and the moving plate 222. Place the rectangular shell 11 on one side of the moving plate 222 and make the first rectangular block 223 and the second rectangular block 224 on both sides fit together. The magnet 2210 prevents the two from separating easily.

[0042] Then, the rectangular shell 11 is pushed towards the evaporator, and the probe 12 is passed through the positioning hole 21-2 and the small hole in the evaporator. During this process, the angle between the first rotating plate 226 and the second rotating plate 228 will gradually decrease, thereby reducing the distance between the moving plate 222 and the fixed plate 221. The moving plate 222 can only move in a direction perpendicular to the evaporator shell, thus ensuring that the probe 12 is inserted and removed vertically, avoiding bending or breakage of the probe 12 due to tilting operation, thereby extending the service life of the temperature sensor.

[0043] When the movable plate 222 and the fixed plate 221 are tightly attached under the action of the magnet 2210, the installation of the rectangular shell 11 is completed. At this time, the installation of the glove box will not be affected. Then connect the wiring port 14 to the designated port, and finally install the glove box to complete the installation of the air conditioner evaporator temperature sensor.

[0044] When disassembly is required, the rectangular shell 11 is pulled away from the evaporator. The second rectangular block 224 drives the first rectangular block 223 to move, which in turn moves the moving plate 222 away from the fixed plate 221. When the two are at their extreme positions, the rectangular shell 11 is pulled again, and the moving plate 222 will not move, thus separating the first rectangular block 223 and the second rectangular block 224, completing the disassembly.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
