Description

Technical Field

[0001] This utility model relates to temperature sensors, and more particularly to a wear-resistant temperature sensor for new energy vehicles. Background Technology

[0002] With the popularization of new energy vehicles, motors and battery packs, as power source devices, have become indispensable components. Therefore, the normal operation of motors and battery packs is of paramount importance, and temperature is a crucial indicator for monitoring their proper functioning. Consequently, some temperature sensors have emerged on the market, such as those with announcement numbers CN210400653U and CN210513440U. However, these original temperature sensors have several drawbacks: when the vehicle is in motion or encounters bumpy road conditions, the wires or lead harnesses of the original temperature sensors are easily worn or broken, resulting in unstable and inaccurate temperature signals, or even no temperature signal detected; during vehicle operation, the connection points between the temperature sensing component and the transmission wires, or between the transmission wires and the connectors, are frequently damaged due to wear, leading to the entire sensor becoming unusable; and the connection points between the original temperature sensors and the motor or battery pack are unstable, easily detaching or losing contact during bumpy rides. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a stable and durable temperature sensor for new energy vehicles that can overcome or at least partially solve the above problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A wear-resistant temperature sensor for new energy vehicles includes an external temperature sensing assembly and a transmission assembly. The external temperature sensing assembly is connected to the transmission assembly. The transmission assembly includes a wire and a connector for connecting to the vehicle's central control system. One end of the wire is connected to the external temperature sensing assembly, and the other end is connected to the connector.

[0006] The transmission component also includes an adjustable slider, which is square in shape and has a circular through hole in the middle. The wire is inserted into the circular through hole of the adjustable slider.

[0007] The conductor is fitted with a wear-resistant and heat-insulating sleeve on the outside.

[0008] Furthermore, the external temperature sensing assembly includes a temperature sensing chip, epoxy colloid, Dummey wire, copper strip, and a shaped insulating adhesive layer. The epoxy colloid is mounted on the outside of the temperature sensing chip. One end of the Dummey wire is flat and connected to the temperature sensing chip, and the other end is connected to the copper strip. The shaped insulating adhesive layer is fitted on the outside of the temperature sensing chip, the Dummey wire, and the copper strip.

[0009] One end of the conductor is connected to a copper strip and a Dummey wire.

[0010] Furthermore, the shaped insulating adhesive layer includes a soft buffer inner adhesive layer and a polytetrafluoroethylene outer adhesive sleeve. The soft buffer inner adhesive layer is fitted over the outside of the temperature sensing chip, Dumme wire, and copper strip, and the polytetrafluoroethylene outer adhesive sleeve is fitted over the outside of the soft buffer sealing inner adhesive layer.

[0011] Preferably, the adjustable slider can be an elastic deformable slider, with longitudinal semi-submerged grooves on both the left and right sides, and longitudinal through holes on the elastic deformable slider.

[0012] Preferably, the adjustable slider can be a polypropylene package, with longitudinal semi-submerged grooves on both the left and right sides and longitudinal through holes on the polypropylene package.

[0013] Preferably, the wear-resistant and heat-insulating sleeve fitting can be a corrugated hose, with one end connected to an adjustable slide and the other end connected to a plug fitting.

[0014] Furthermore, a limiting device is installed on the outer side of the area where the conductor contacts and connects to the external temperature sensing assembly;

[0015] A limiting device is installed on the outer side of the area where the wire contacts the connector;

[0016] The limiting mounting component is U-shaped or elongated, and has C-shaped mounting holes. The size of the C-shaped mounting holes matches the outer diameter of the conductor.

[0017] The inner side of the opening area of ​​the limiting mounting part can be fitted with adhesive so that the opening of the limiting mounting part can be bonded together as one piece.

[0018] Furthermore, the connector assembly includes a terminal connector that enables a stable connection between the wire and the connector assembly, and transmits the temperature signal sensed by the external temperature sensing assembly to the connector assembly.

[0019] When the connector is connected to the vehicle's central control system, the temperature signal sensed by the external temperature sensing assembly can be transmitted to the vehicle's central control system.

[0020] Furthermore, the side of the connector is provided with a snap-fit ​​groove, which enables the connector to be stably connected to the connector of the vehicle's main control system without shaking or misalignment.

[0021] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0022] 1. This utility model, by setting a wear-resistant and heat-insulating sleeve on the outside of the wire, can enhance the wear resistance, abrasion resistance, and anti-breakage performance of the wire of the temperature sensor when the car equipped with the temperature sensor is driving or encountering bumpy road conditions. At the same time, it can also block the transmission of high temperature from components such as motors and battery packs to different wire locations, thus extending the service life of the temperature sensor wire.

[0023] 2. The adjustable slider and its sliding connection design on the conductor are used. When the adjustable slider is an elastic deformable slider, it is made of high temperature resistant composite rubber material. The conductor is installed in the longitudinal through hole of the elastic deformable slider, which can prevent the conductor from being misaligned, running away or sliding to the left or right, and can improve the stability and wear resistance of the conductor in the connection area of ​​the elastic deformable slider.

[0024] When the adjustable slider is a nylon adhesive or a polypropylene encapsulation, the nylon adhesive or polypropylene encapsulation can be embedded in the temperature sensing mounting hole of the car motor or battery pack to prevent the external temperature sensing assembly of the temperature sensor from falling off or disconnecting from the temperature sensing mounting hole of the motor or battery pack when the car is running with bumps, thus ensuring the installation stability of the external temperature sensing assembly in the temperature sensor.

[0025] Meanwhile, the adjustable slider design can also prevent dust or rainwater and other debris from entering the temperature sensing mounting holes of the motor or battery pack.

[0026] 3. By installing limiting stickers at the contact connection area between the conductor and the external temperature sensing assembly, adjacent conductors can be spaced a distance apart to prevent them from touching each other, which can reduce mutual friction between adjacent conductors. At the same time, it can also improve the high temperature resistance of the connection area between the conductor and the adjustable slider and extend the service life of the conductor.

[0027] Installing a limiting device at the contact connection area between the wire and the connector can reduce friction between the wire and the connector, prevent the wire from disengaging when the vehicle is moving around bumps, and improve the stability of the connection area between the wire and the connector.

[0028] In summary, this utility model, through the design of an adjustable slider, enables a stable connection between the external temperature sensing assembly of the temperature sensor and the motor or battery pack, and prevents dust or rainwater and other debris from falling into the temperature sensing mounting hole where the temperature sensor connects to the motor or battery pack. Furthermore, the design of the wear-resistant and heat-insulating sleeve and the limiting mounting component enhances the wear resistance or abrasion resistance of the temperature sensor wires or lead harness during vehicle operation.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0040] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0041] Example 1:

[0042] Reference Figure 1 , Figure 2 A wear-resistant temperature sensor for new energy vehicles, wherein an external temperature sensing assembly 1 is connected to a transmission component, the transmission component includes a wire 2 and a connector 3 connected to the vehicle's main control system, one end of the wire 2 is connected to the external temperature sensing assembly 1 and the other end is connected to the connector 3;

[0043] The transmission component also includes an adjustable slider 4, which is square in shape and has a circular through hole in the middle. The wire 2 can be inserted through the circular through hole of the adjustable slider 4. A wear-resistant and heat-insulating sleeve 5 is fitted on the outside of the wire 2.

[0044] The external temperature sensing assembly 1 includes a temperature sensing chip 6, epoxy colloid, Dummey wire 7, copper strip 8, and a shaped insulating layer. The epoxy colloid is installed on the outside of the temperature sensing chip 6. One end of the Dummey wire 7 is flat and connected to the temperature sensing chip 6, and the other end of the Dummey wire 7 is connected to the copper strip. The shaped insulating layer is fitted on the outside of the temperature sensing chip 6, the Dummey wire 7, and the copper strip 8. The wear-resistant and heat-insulating sleeve 5 can be a corrugated hose. One end of the wear-resistant and heat-insulating sleeve 5 is connected to the adjustable slide 4, and the other end is connected to the plug fitting 3.

[0045] In use, the external temperature sensing assembly 1 of the temperature sensor is installed at the temperature sensing mounting hole on the motor or battery pack. The temperature sensing chip 6 in the external temperature sensing assembly 1 can transmit the sensed temperature signal to the vehicle's main control system through the Dummey wire 7, copper strip 8, wire 2 and connector 3, so that the main control system can monitor the temperature of the motor or battery pack at any time during vehicle operation. When the temperature is too high, too low or no temperature signal is received, an alarm will be issued to remind the driver.

[0046] By installing a wear-resistant and heat-insulating sleeve 5 on the outside of the wire 2, the wear resistance, abrasion resistance, and anti-breakage performance of the wire 2 of the temperature sensor can be enhanced when the car equipped with the temperature sensor is driving or encountering bumpy road conditions. At the same time, it can also block the transmission of high temperature from components such as motors and battery packs to different wire locations, thus extending the service life of the wire 2 of the temperature sensor.

[0047] Example 2:

[0048] Reference Figures 2-4 Based on Example 1, the difference is that the shaped insulating adhesive layer includes a soft buffer inner adhesive layer 9 and a polytetrafluoroethylene outer adhesive sleeve 10. The soft buffer inner adhesive layer 9 is fitted on the outside of the temperature sensing chip 6, Dummey wire 7, and copper strip 8, and the polytetrafluoroethylene outer adhesive sleeve 10 is fitted on the outside of the soft buffer sealing inner adhesive layer 9.

[0049] The design of the soft buffer inner adhesive layer 9 ensures that the relative positions of the temperature sensing chip 6, Dummey wire 7, and copper strip 8 remain unchanged, while also serving as an encapsulation and positioning function; the polytetrafluoroethylene outer sleeve 10 is transparent in its entirety, and its design prevents the internal components of the external temperature sensing assembly 1 from directly contacting the temperature sensing mounting holes of the motor or battery pack, thus preventing high temperature or friction from causing the external temperature sensing assembly 1 to fail and become unusable.

[0050] The adjustable slide 4 can be an elastic deformable slide. The elastic deformable slide has longitudinal semi-submerged grooves on the left and right sides and longitudinal through holes on the elastic deformable slide. The matching design of the longitudinal semi-submerged grooves and longitudinal through holes makes it easier for the wire 2 to slide from the left and right sides of the adjustable slide 4 to the longitudinal through holes, and makes it easier to disassemble or replace the adjustable slide 4 on the wire 2.

[0051] This invention features an adjustable slider 4 mounted on the conductor 2, allowing the adjustable slider 4 to slide on the conductor 2. When the adjustable slider 4 is an elastic deformable slider, it is made of high-temperature resistant composite rubber material. The conductor 2 is mounted in the longitudinal through hole of the elastic deformable slider, which can prevent the conductor 2 from being misaligned, running away, or sliding to the left or right, thereby improving the stability and wear resistance of the conductor 2 in the connection area of ​​the elastic deformable slider.

[0052] When the adjustable slider 4 is a nylon adhesive or a polypropylene encapsulation, the nylon adhesive or polypropylene encapsulation can be embedded in the temperature sensing mounting hole of the car motor or battery pack to prevent the external temperature sensing assembly 1 of the temperature sensor from falling off or disconnecting from the temperature sensing mounting hole of the motor or battery pack when the car is running bumpy, thus ensuring the installation stability of the external temperature sensing assembly 1 in the temperature sensor.

[0053] Meanwhile, the design of the adjustable slider 4 can also prevent dust or rainwater and other debris from entering the temperature sensing mounting hole of the motor or battery pack; the design of the longitudinal semi-submerged groove on the adjustable slider 4 allows the wires to slide out or be inserted in the longitudinal semi-submerged groove, realizing the replaceable function of the adjustable slider 4.

[0054] Example 3:

[0055] Reference Figure 5Based on Embodiment 1, the difference is that the connector 3 is provided with a terminal connector 12, which enables the wire 2 to be stably connected to the connector 3 and transmits the temperature signal sensed by the external temperature sensing assembly 1 to the connector 3.

[0056] When connector 3 is connected to the vehicle's central control system, the temperature signal sensed by external temperature sensing assembly 1 can be transmitted to the vehicle's central control system.

[0057] The connector 3 of this utility model is equipped with a terminal connector 12 inside, which can make the connection between the wire 2 and the connector 3 more stable, and it is not easy for the wire to shift or fall off, ensuring that the temperature signal of the motor or battery pack and other accessories equipped with the temperature sensor can be normally transmitted to the vehicle's main control system.

[0058] The surface of the connector 3 is provided with a snap-fit ​​groove, which enables the connector 3 to be stably connected to the connector of the vehicle's main control system without shaking or misalignment. The design of the snap-fit ​​groove can prevent the connector 3 from disengaging from the vehicle's main control system when the vehicle is bumpy, thus improving the connection stability between the connector 3 and the vehicle's main control system.

[0059] Example 4:

[0060] Reference Figures 6-9 Based on Example 1, the difference is that a limiting sticker 11 is installed at the contact connection area between the wire and the external temperature sensing assembly 1, which can keep adjacent wires 2 apart by a certain distance and prevent them from touching each other, thereby reducing mutual friction between adjacent wires 2. At the same time, it can also improve the high temperature resistance of the connection area between the wire 2 and the adjustable slider 4 and extend the service life of the wire.

[0061] In addition, a limiting attachment 11 can also be installed on the outside of the area where the wire 2 contacts and connects with the adjustable slider 4; at this time, the limiting attachment 11 installed in the area where the wire 2 contacts and connects with the adjustable slider 4 can prevent relative sliding friction between the wire 2 and the adjustable slider 4 in the wear-resistant temperature sensor and the temperature sensing mounting hole of the motor or battery pack on which the temperature sensor is installed, thus avoiding the wire 2 of the temperature sensor being worn out or broken at the temperature sensing mounting hole of the motor or battery pack.

[0062] Installing a limiting sticker 11 at the contact connection area between the wire 2 and the connector 3 can reduce the friction between the wire 2 and the connector 3, prevent the wire 2 and the connector 3 from disengaging when the vehicle is running bumpy, and make the connection area between the wire 2 and the connector 3 more stable.

[0063] The limiting mounting component 11 is U-shaped or elongated, and has C-shaped mounting holes. The size of the C-shaped mounting holes matches the outer diameter of the wire 2. When the limiting mounting component 11 is U-shaped, adhesive can be applied to the inner side of the opening area of ​​the limiting mounting component 11, so that the opening of the limiting mounting component can be bonded together. When the limiting mounting component 11 is elongated, adhesive layers can be applied or coated to the inner side of the symmetrical areas at both ends of the limiting mounting component 11 along the central plane. These designs make it more convenient and provide better stable adhesion when the limiting mounting component 11 is installed at the corresponding area of ​​the temperature sensor.

[0064] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and concept of the present utility model, should be included within the protection scope of the present utility model.
