Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0030] This application provides a sensor module 100, such as... Figures 1 to 4 As shown, the sensor module 100 includes a sensor assembly 1 and a housing 2. An adhesive backing 3 is provided on one side of the sensor assembly 1 adjacent to the housing 2, and the sensor assembly 1 is fixed to the inside of the housing 2 by the adhesive backing 3. The housing 2 serves to support and protect the sensor assembly 1. This method of fixing the sensor assembly 1 to the housing 2 allows for rapid assembly of the sensor module 100 without the need for additional screws or clips, resulting in low cost. Furthermore, the sensor module 100 is thinner and lighter, making it suitable for installation in space-constrained structures, thus contributing to the miniaturization and lightweight design of the sensor module 100.

[0031] In some exemplary embodiments, such as Figure 1 and Figure 2As shown, the housing 2 comprises an end wall 21 and a plurality of side walls 22 connected with the end wall 21, and the end wall 21 and the plurality of side walls 22 enclose a cavity with an open side, in which the sensor assembly 1 is placed. The housing 2 is simple in structure and easy to process. The back adhesive 3 is a kind of adhesive material coated on the sensor assembly 1. The back adhesive 3 is arranged on the side of the sensor assembly 1 adjacent to the end wall 21 and is fixed to the inner wall surface of the end wall 21 of the housing 2, so as to fix the sensor assembly 1 to the housing 2. The sensor assembly 1 can be quickly and conveniently installed in the housing 2 through the back adhesive 3, while maintaining the compactness of the overall structure of the sensor module 100, which helps to reduce the overall thickness of the sensor module 100 and enables the sensor module 100 to be installed in a structure with limited space.

[0032] As shown in some example embodiments, Figure 1 and Figure 2 The sensor assembly 1 comprises a circuit board 11, a sensor (not shown) and a wire harness 12. The sensor is arranged on the circuit board 11. The circuit board 11 is provided with a wiring portion 112 (as shown in Figure 2 ) to be electrically connected with the wire harness 12. The wire harness 12 is electrically connected with the circuit board 11 and the sensor through the wiring portion 112 of the circuit board 11 for signal transmission and power supply. The back adhesive 3 is arranged on the side of the circuit board 11 adjacent to the housing 2 for fixing the sensor assembly 1 to the housing 2. The wiring portion 112 and the back adhesive 3 are arranged on the same side of the circuit board 11.

[0033] The end wall 21 of the housing 2 is provided with a glue pouring port 211 for injecting the sealing glue 5. The glue pouring port 211 corresponds to the wiring portion 112 of the circuit board 11, so that the sealing glue 5 can cover the wiring portion 112 to ensure the reliability of the electrical connection. One of the side walls 22 of the housing 2 adjacent to the glue pouring port 211 is provided with a wire passing port 221 corresponding to the wire harness 12 for the wire harness 12 to pass through.

[0034] As shown in some example embodiments, Figure 2 and Figure 3 The sensor assembly 1 further comprises a reinforcing plate 13 fixed to the side of the circuit board 11 away from the end wall 21. The reinforcing plate 13 is usually made of metal, for example, the reinforcing plate 13 can be a steel sheet. The reinforcing plate 13 is used to reinforce or support the circuit board 11 to prevent the circuit board 11 from being deformed or damaged in vibration or impact.

[0035] As shown in some example embodiments, Figure 2 and Figure 3As shown, circuit board 11 is a flexible circuit board. The flexible circuit board can be integrated with reinforcing plate 13 to form a unified structure. This integrated structure of the flexible circuit board and reinforcing plate 13 is, on the one hand, thinner and lighter, helping to reduce the overall size and weight of the structure; on the other hand, it helps to enhance the mechanical strength and rigidity of the structure. The sensor can be an elastic wave sensor to monitor the vibration and deformation of an object. Elastic wave sensors have a small overall size, for example, a thickness of only about 3 mm, are easy to install, and can be more flexibly arranged in space-constrained structural areas. It should be understood that the sensor can also be other sensors, such as temperature sensors, humidity sensors, etc., to monitor other parameters of the object.

[0036] In some exemplary embodiments, such as Figures 1 to 3 As shown, the sensor module 100 also includes double-sided adhesive 4. The double-sided adhesive 4 is disposed on the side of the sensor assembly 1 opposite to the backing adhesive 3. The double-sided adhesive 4 and the backing adhesive 3 are disposed on opposite sides of the integrated structure of the flexible circuit board and the reinforcing plate 13; more specifically, the backing adhesive 3 is disposed on the flexible circuit board, and the double-sided adhesive 4 is disposed on the reinforcing plate 13. The double-sided adhesive 4 is configured to fix the sensor module 100 to the object to be deformed. This fixing method is simple, quick, and helps save space.

[0037] like Figures 1 to 3 The sensor module 100 shown is stacked vertically, resulting in a compact structure. Figure 1 and Figure 2 The assembly process of the sensor module 100 shown is as follows: the top of the integrated structure of the flexible circuit board and the reinforcing plate 13 is covered with adhesive 3, and then it is fixed to the outer shell 2 by the adhesive 3; then double-sided tape is fixed on the side of the reinforcing plate 13 away from the adhesive 3; finally, sealant 5 is injected into the glue inlet 211 to seal and fix the wiring part 112 of the circuit board 11.

[0038] Figure 3 The sensor module 100 shown is... Figure 1 and Figure 2 The main difference of the sensor module 100 shown is that it does not have a housing; the rest of the structure is largely the same. Its advantage is that the overall size of the sensor module 100 is smaller, with a height of less than 2mm, making it easier to place in space-constrained locations. Figure 3 The assembly process of the sensor module 100 shown is similar to Figure 1 and Figure 2 The sensor module 100 shown is similar, wherein the adhesive 3 is provided on one side of the integrated structure of the flexible circuit board and the reinforcing plate 13, and the double-sided adhesive 4 is provided on the opposite side. The adhesive 3 and the double-sided adhesive 4 can be used to fix the sensor module 100 to different structures respectively.

[0039] This application also provides a vehicle, such as... Figure 4As shown, the system includes a vehicle body and a sensor module 100 according to any of the foregoing embodiments, with the sensor module 100 fixed to the vehicle body. The sensor module 100 can determine whether the vehicle body has been subjected to external impact or overload, and transmit the data to the driver and maintenance personnel, allowing them to monitor the vehicle's impact or overload status at any time, thus improving the vehicle's intelligence level. The sensor module 100 can be installed in a space-constrained structure on the vehicle body and can be fixed to the vehicle body using adhesive 3, thereby making full use of the vehicle body's space.

[0040] In some exemplary embodiments, such as Figure 4 As shown, the vehicle body includes a battery chassis on which a sensor module 100 is mounted; and / or the vehicle body includes a bumper on which a sensor module 100 is mounted. The sensor module 100 can be installed in parts of the vehicle body that are prone to collisions and deformation, such as the battery chassis, bumper, and doors, to understand the impact conditions on these parts and locate the damaged areas.

[0041] In some exemplary embodiments, such as Figure 4 As shown, the vehicle body includes a battery chassis, which comprises a bottom protection plate 6 and a water-cooled plate 7. The bottom protection plate 6 and water-cooled plate 7 are components of the battery chassis. The bottom protection plate 6 is located below the battery pack and is used to protect it. The water-cooled plate 7 is typically located below the battery pack and is used for heat exchange with it. A sensor module 100 is disposed between the bottom protection plate 6 and the water-cooled plate 7, and is fixed to the bottom protection plate 6 and / or the water-cooled plate 7. The sensor module 100 is used to detect the external forces and vibration deformation experienced by the battery chassis, determining whether the battery chassis has been subjected to external impact or overload, and locating the damaged area. The sensor signals are analyzed by the controller and transmitted to terminal devices such as the onboard computer system, allowing drivers and maintenance personnel to monitor the condition of the battery chassis at any time, promptly identify potential problems, and perform maintenance and repairs in advance. This extends battery life, reduces maintenance costs, improves understanding of the battery chassis condition, and effectively reduces safety risks. The sensor module 100 can be fixed to the bottom cover plate 6 and / or the water-cooling plate 7 by adhesive means, such as by double-sided adhesive 4 and / or by adhesive backing 3. This fixing method helps to place the sensor module 100 in the limited space between the bottom cover plate 6 and the water-cooling plate 7, making full use of the space inside the battery chassis and avoiding the occupation of other areas.

[0042] In some exemplary embodiments, such as Figure 4As shown, the sensor module 100 is provided in plurality, and the plurality of sensor modules 100 are arranged along the circumferential direction of the bottom guard plate 6 and / or the water-cooling plate 7. The bottom guard plate 6 and the water-cooling plate 7 can be substantially rectangular in shape, and the plurality of sensor modules 100 can be arranged at positions close to the edges along the length direction and / or the width direction of the rectangular shape. As shown in the figure, the plurality of sensor modules 100 are arranged along the length direction of the rectangular shape, including the positions at the four corners. The plurality of sensor modules 100 can be substantially uniformly spaced, or densely arranged at some key positions according to actual needs. By uniformly arranging the plurality of sensor modules 100 in different areas, the vibration and deformation states of each area can be ensured to be collected and analyzed in real time, so as to comprehensively monitor the bumping conditions of the battery chassis and ensure the stability and accuracy of the monitoring data. The wire passing ports 221 of the plurality of sensor modules 100 can be arranged towards the same direction or opposite directions, so as to facilitate the wiring of the cables and improve the overall aesthetics of the cable wiring.
