[0002] With the promotion of energy conservation and environmental protection, the number of new energy vehicles is increasing. As a core component of new energy vehicles, the operating temperature of power batteries directly affects their performance and safety. If the battery or other key components overheat while driving, a new energy vehicle may cause safety accidents such as fire or explosion. Temperature monitoring can obtain real-time battery temperature information, detect temperature anomalies promptly, and take appropriate measures to ensure that the battery operates within the appropriate temperature range, avoiding performance degradation and safety hazards caused by overheating or overcooling, and protecting the driver's life.

[0003] At present, the temperature monitoring of new energy vehicle batteries is usually completed by temperature sensors installed on the battery surface. However, there is a difference between the temperature inside the multiple battery blocks of new energy vehicles and the temperature on the battery surface. The temperature inside the battery blocks is often higher. This makes it difficult to obtain the accurate temperature value of the new energy vehicle battery in a timely manner, resulting in the disadvantage of delayed battery overheating judgment and posing certain safety hazards. For this reason, the present application proposes a vehicle temperature sensing device. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0024] A vehicle temperature sensing device, such as Figures 1-6 As shown, it is specifically applied to the new energy vehicle battery pack 1, including a first mounting rail 2 and a second mounting rail 3. The first mounting rail 2 and the second mounting rail 3 are arranged on the top of the new energy vehicle battery pack 1, and the second mounting rail 3 is provided with multiple and distributed on both sides of the first mounting rail 2. The first mounting rail 2 is aligned with the battery gap in the length direction of the new energy vehicle battery pack 1, and the second mounting rail 3 is aligned with the battery gap in the width direction of the new energy vehicle battery pack 1. The first mounting rail 2 and the second mounting rail 3 are assembled at the battery gap at the top of the new energy vehicle battery pack 1, and the ends of the first mounting rail 2 and the second mounting rail 3 are connected and fixed to the new energy vehicle battery pack 1. The first mounting rail 2 and the second mounting rail 3 can limit the batteries in the new energy vehicle battery pack 1. The first mounting rail 2 and the second mounting rail 3 are provided with a through groove 4, which is aligned with the battery gap of the new energy vehicle battery pack 1 and is conductive, which is beneficial to the heat dissipation between the batteries in the new energy vehicle battery pack 1.

[0025] In this embodiment, a temperature sensor body 5 is plugged into the first mounting rail 2 and the second mounting rail 3. A thermistor rod 8 is provided at the bottom of the temperature sensor body 5 and extends into the battery gap of the new energy vehicle battery pack 1. The thermistor rod 8 passes through the through slot 4. By passing the thermistor rod 8 at the bottom end of the temperature sensor body 5 through the through slot 4 and extending into the battery gap in the new energy vehicle battery pack 1, the temperature information between the batteries in the new energy vehicle battery pack 1 can be detected in real time. Moreover, since the thermistor rod 8 extends into the battery gap, the temperature information obtained is more accurate and effective.

[0026] In a further embodiment, a card strip 6 is provided on both sides of the upper surface of the first mounting rail 2 and the second mounting rail 3, the temperature sensor body 5 is embedded between the pair of card strips 6, and a card slot 7 is provided at the bottom of the pair of card strips 6 facing each other. Card blocks 9 that can extend into the card slot 7 are movably embedded on both sides of the bottom of the temperature sensor body 5. A pressure block 11 is movably provided on the side walls of the temperature sensor body 5. A connecting plate 12 is connected between the pressure block 11 and the card block 9. A sleeve 14 aligned with the pressure block 11 is horizontally fixed in the temperature sensor body 5, and a spring 13 is provided in the sleeve 14. The two ends of the spring 13 are respectively connected to a pair of pressure blocks 11. After the temperature sensor body 5 is embedded between the pair of card strips 6, the elastic force of the spring 13 pushes the pair of connecting plates 12 away from each other, pushing the card block 9 to extend out of the bottom of the temperature sensor body 5 and embed into the card slot 7 on the card strip 6. In this way, the temperature sensor body 5 can be limited and connected to prevent the temperature sensor body 5 from loosening and falling off. By pressing the pressure block 11 to push the pair of connecting plates 12 to drive the card block 9 to move out of the card slot 7, the temperature sensor body 5 can be pulled out from between the pair of card strips 6, thereby realizing the quick plug-in and assembly of the temperature sensor body 5.

[0027] In this embodiment, sliding grooves 16 for horizontal movement of the clamping block 9 are opened on both sides of the bottom of the temperature sensor body 5, and a through hole 17 that is conductive to the interior of the temperature sensor body 5 is opened on the top wall of the sliding groove 16. The connecting plate 12 passes through the through hole 17 to connect the pressure block 11 and the clamping block 9.

[0028] Furthermore, a circuit board 15 is assembled in the temperature sensor body 5, and the thermistor rod 8 is connected to the circuit board 15. A fourth conductive contact 20 is embedded on the inner wall of the card slot 7, and a first conductive contact 10 is embedded on the end surface of the card block 9 extending outside the temperature sensor body 5. A second conductive contact 18 is horizontally embedded on the top of the card block 9. The second conductive contact 18 is connected to the first conductive contact 10. A third conductive contact 19 is provided on the circuit board 15 and is distributed parallel to the second conductive contact 18. The end of the second conductive contact 18 away from the first conductive contact 10 extends into the temperature sensor body 5 and is in conductive contact with the third conductive contact 19. The card block 9 is engaged with the card slot 7 on the card strip 6. After that, the first conductive contact 10 on the card block 9 contacts the fourth conductive contact 20 in the card slot 7. It is only necessary to connect the fourth conductive contact 20 corresponding to the pair of card strips 6 on each first mounting rail 2 and second mounting rail 3 to the positive and negative poles of the power supply respectively, and cooperate with the circuit conduction of the first conductive contact 10, the second conductive contact 18 and the third conductive contact 19. In this way, the temperature sensor body 5 can be connected to the circuit at the same time as the pair of card strips 6 are inserted and assembled. There is no need to arrange the circuit separately for each temperature sensor body 5, making the installation and replacement of the temperature sensor body 5 simpler and faster.

[0029] The working principle of the utility model is as follows: when in use, the first mounting rail 2 and the second mounting rail 3 are assembled at the battery gap at the top of the new energy vehicle battery pack 1, and the ends of the first mounting rail 2 and the second mounting rail 3 are connected and fixed to the new energy vehicle battery pack 1. The first mounting rail 2 and the second mounting rail 3 can limit the batteries in the new energy vehicle battery pack 1, and the through grooves 4 opened on the first mounting rail 2 and the second mounting rail 3 and connected to the battery gap are conducive to the heat dissipation between the batteries in the new energy vehicle battery pack 1. The thermistor rod 8 at the bottom end of the temperature sensor body 5 is inserted into the battery gap in the new energy vehicle battery pack 1 through the through groove 4, and then the temperature sensor body 5 is embedded between a pair of clips 6 on the first mounting rail 2 or the second mounting rail 3, so that the temperature information between the batteries in the new energy vehicle battery pack 1 can be detected in real time. Furthermore, after the temperature sensor body 5 is embedded between the pair of clips 6, the elastic force of the spring 13 pushes the pair of connecting plates 12 away from each other, pushing the clip 9 out of the temperature sensor body. The bottom of the temperature sensor body 5 is embedded in the slot 7 on the card strip 6, thereby limiting the position of the temperature sensor body 5 and preventing the temperature sensor body 5 from loosening and falling off. By pressing the pressure block 11 to push the pair of connecting plates 12 to drive the card block 9 to move out of the slot 7, the temperature sensor body 5 can be pulled out between the pair of card strips 6, so that the temperature sensor body 5 can be quickly plugged and assembled. Further, after the card block 9 is engaged with the slot 7 on the card strip 6, the first conductive contact 10 on the card block 9 contacts the fourth conductive contact 20 in the slot 7. It is only necessary to connect the fourth conductive contact 20 corresponding to the pair of card strips 6 on each first mounting rail 2 and second mounting rail 3 to the positive and negative poles of the power supply respectively, and cooperate with the circuit conduction of the first conductive contact 10, the second conductive contact 18 and the third conductive contact 19, so that the temperature sensor body 5 can be connected to the circuit at the same time as the pair of card strips 6 are inserted and assembled. There is no need to arrange the circuit separately for each temperature sensor body 5, which makes the installation and replacement of the temperature sensor body 5 simpler and faster.
