DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solution and advantages of the utility model more clear, the embodiments of the utility model will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0039] Reference Figures 1 to 23, the embodiment of the present application provides a battery device 100 with a collision detection function, including a battery assembly 1 and a plurality of collision sensors 2. The battery assembly 1 includes a battery chassis 11 and a battery pack 12, the battery chassis 11 includes a battery mounting portion 111, and the battery pack 12 is fixed to the battery mounting portion 111. The term "battery mounting portion" described herein refers to a portion of the battery chassis 11 itself, and the battery pack 12 is fixed to this portion. In order to facilitate the realization of the collision detection function, the battery mounting portion 111 is divided into a plurality of collision identification areas 112, and the size and shape of these collision identification areas 112 can be designed as needed to better adapt to different application scenarios. A plurality of collision sensors 2 are installed to at least one of the battery chassis 11 and the battery pack 12, and the plurality of collision sensors 2 are cooperatively arranged to determine the collision identification area 112 where the collision position is located. Among them, the collision sensor 2 can be an elastic wave sensor. When the battery device 100 is subjected to a collision, the collision sensor 2 can detect the elastic wave signal generated by the collision and output an electrical signal. According to the electrical signal generated by the collision sensor 2 , the collision identification area 112 where the collision sensor 2 is located can be determined by a suitable algorithm, so as to locate the collision position, and the collision intensity can also be determined.

[0040] The battery device 100 of the embodiment of the present application divides the battery chassis 11 into a plurality of collision identification areas 112, and after the collision sensor 2 detects the occurrence of a collision event, the collision identification area 112 where the collision sensor 2 is located is determined by an appropriate algorithm, so that it is possible to determine which areas have been hit and the intensity of the collision, thereby helping to determine the damaged location and degree of damage of the battery device 100, improving the safety and reliability of the use of the battery device 100, and also providing useful information for maintenance personnel, so that the maintenance personnel can perform targeted maintenance and improve maintenance efficiency. In addition, by dividing the battery chassis 11 into a plurality of collision identification areas 112 and determining the collision identification area 112 where the collision is located based on the detection results of the collision sensor 2, compared with the method of determining the specific coordinate point where the collision is located, the judgment logic of the collision position is further simplified, the complexity of the algorithm is reduced, and the battery device 100 can be more quickly detected for collision.

[0041] In some exemplary embodiments, reference Figures 1 to 7 Each collision recognition area 112 corresponds to at least one collision sensor 2, and the number of collision sensors 2 is greater than or equal to the number of collision recognition areas 112 to be detected, so as to improve the coverage of the collision sensors 2 and ensure the accuracy and comprehensiveness of collision detection.

[0042] When a collision occurs, the external force impacts the battery chassis 11 and is transmitted to the battery pack 12 located on the battery chassis 11. Therefore, by installing multiple collision sensors 2 to the battery chassis 11 and / or the battery pack 12, the collision sensor 2 can collect the elastic wave signal generated by the collision. Among them, the collision sensor 2 corresponding to a collision identification area 112 can be installed on the battery chassis 11 and arranged in the collision identification area 112. This arrangement allows the collision sensor 2 to detect the collision acting on the battery chassis 11, and determine the collision identification area 112 where the collision is located through an algorithm. Alternatively, the collision sensor 2 corresponding to a collision identification area 112 can be installed on the battery pack 12, and the projection of the collision sensor 2 on the battery chassis 11 is located in the corresponding collision identification area 112. This arrangement allows the collision sensor 2 to detect the collision acting on the battery pack 12, and the collision identification area 112 where the collision is located can be determined through an algorithm.

[0043] Therefore, the collision sensor 2 can be flexibly arranged according to actual needs, and can be installed on the battery chassis 11 or the battery pack 12, so as to achieve all-round collision detection of the battery device 100.

[0044] In some exemplary embodiments, reference Figures 2 to 4 The battery installation portion 111 is evenly divided into a plurality of collision recognition areas 112 according to geometric dimensions.

[0045] The battery chassis 11 can be regarded as a whole and divided into a plurality of collision identification areas 112. The number of collision identification areas 112 can be customized, such as 4, 6 or other even-numbered areas. When the battery chassis 11 is a symmetrical structure, it can be divided symmetrically according to the geometric structure, and the number or distribution of the collision identification areas 112 is symmetrical. By dividing the battery mounting portion 111 according to the geometric size, the size and shape of each collision identification area 112 can be roughly the same, which can ensure the consistency of collision detection, simplify the collision detection algorithm, and improve the efficiency of collision detection.

[0046] In some exemplary embodiments, reference Figures 2 to 4 The battery mounting portion 111 is rectangular, and the plurality of collision identification areas 112 are arranged in at least one row and at least one column.

[0047] Figures 2 to 4The example shows that the battery chassis 11 is evenly divided into 6 collision identification areas 112, and the 6 collision identification areas 112 are arranged in two rows and three columns. The number of rows and columns can be customized as needed. Setting a larger number of rows and columns can make the collision detection more detailed and accurate, while setting a smaller number of rows and columns can simplify the algorithm and make the detection faster. By dividing the rectangular battery mounting portion 111 into a layout of at least one row and at least one column, the division method is simple, the divided collision identification areas 112 are neat and orderly, and it can also ensure that the collision detection covers the corners of the battery device 100, so that the collision detection is more accurate, efficient and comprehensive.

[0048] In some exemplary embodiments, Figures 5 to 7 As shown, the multiple collision identification areas 112 include at least one first collision identification area 1121 and at least one second collision identification area 1122, and the structural strength of the first collision identification area 1121 is greater than the structural strength of the second collision identification area 1122. In other words, relatively speaking, the first collision identification area 1121 is a strong structural area, and the second collision identification area 1122 is a weak structural area. Therefore, the multiple collision identification areas 112 can be divided according to the structural strength. For this division method, the collision sensor 2 can have multiple arrangements. Multiple collision sensors 2 can all be set corresponding to the first collision identification area 1121; or, multiple collision sensors 2 can all be set corresponding to the second collision identification area 1122; or, a part of the multiple collision sensors 2 can be set corresponding to the first collision identification area 1121, and another part of the collision sensors 2 can be set corresponding to the second collision identification area 1122. Which arrangement method is used specifically also needs to consider the space limitation of the actual structure where the collision sensor 2 is located. In addition, in order to determine these areas, one method is to perform simulation analysis on the battery chassis 11, and judge the strong structural area and weak structural area of ​​the battery chassis 11 according to the simulation results. A plurality of collision recognition areas 112 are divided according to the structural strength, and it is determined which collision recognition area 112 the collision sensor 2 corresponds to. Therefore, the degree of threat to the battery chassis 11 in a collision can be easily and preliminarily judged in combination with the structural strength of the collision recognition area 112. Such a preliminary judgment is conducive to quickly responding to collision events and taking appropriate measures.

[0049] In some exemplary embodiments, Figures 5 to 7As shown, the battery mounting portion 111 is rectangular, and at least one reinforcing rib 113 is provided on the battery mounting portion 111. The at least one reinforcing rib 113 divides the battery mounting portion 111 into a plurality of partitions. The first collision identification area 1121 is an annular area located at the edge of the partition, and the second collision identification area 1122 is located within the first collision identification area 1121. The annular area closer to the reinforcing rib 113 has a greater strength, and the area farther from the reinforcing rib 113 has a relatively smaller strength. Different collision identification areas 112 are divided according to the structural strength of the battery chassis 11 based on the reinforcing rib 113, and the structural characteristics of the battery chassis 11 are directly used for division. This division method is not only intuitive and simple, but also very practical.

[0050] In some exemplary embodiments, Figures 1 to 7 As shown, the collision sensor 2 is disposed below the battery chassis 11 , or the collision sensor 2 is disposed at the bottom of the battery pack 12 , or the collision sensor 2 is disposed at the side of the battery pack 12 .

[0051] When the collision sensor 2 is disposed below the battery chassis 11 , since the space below the battery chassis 11 is relatively large, the collision sensor 2 can be flexibly arranged to obtain a better data collection effect, thereby more accurately detecting the collision position and collision intensity of the vehicle.

[0052] When the collision sensor 2 is arranged at the bottom of the battery pack 12, that is, the inner bottom surface 121 of the battery pack, since the battery cells 124 are arranged inside the battery pack 12, the middle area space inside the battery pack 12 is occupied by the battery cells 124, and the collision sensor 2 cannot be arranged. Therefore, the collision sensor 2 is usually arranged at the corner or edge position of the inner bottom surface 121 of the battery pack.

[0053] The collision sensor 2 can be arranged on the side of the battery pack 12, specifically, on the inner wall 122 or the outer wall 123 of the battery pack 12. There is no requirement for the installation height of the collision sensor 2 on the side wall, as long as it does not interfere with the structure. The effect of the collision sensor 2 being arranged on the inner wall 122 and the outer wall 123 is basically the same, but considering the installation requirements or the requirements for the collision sensor 2 (such as waterproof level, size, etc.), the collision sensor 2 may be arranged on the inner wall 122 and the outer wall 123 differently.

[0054] In addition, the collision sensor 2 can also be arranged on the outer bottom surface of the battery pack 12, that is, the bottom surface of the battery mounting portion 111 adjacent to the outside of the battery pack 12. This arrangement can avoid the collision sensor 2 from interfering with the battery cells 124 inside the battery pack 12. Alternatively, the collision sensor 2 can also be arranged on the upper surface of the battery mounting portion 111, that is, the surface of the battery mounting portion 111 adjacent to the battery pack 12.

[0055] Of course, among the multiple collision sensors 2, some collision sensors 2 may be arranged below the battery chassis 11, and some collision sensors 2 may be arranged at the bottom and / or side of the battery pack 12; or, some collision sensors 2 may be arranged at the bottom of the battery pack 12, and some collision sensors 2 may be arranged at the side of the battery pack 12.

[0056] It should be noted that the above-mentioned arrangements of the collision sensor 2 can be combined with various ways of dividing the collision identification area 112, and can achieve the purpose of collision detection of the battery chassis 11. By reasonably selecting the arrangement position of the collision sensor 2 and combining various ways of dividing the collision identification area 112, a variety of collision detection schemes can be implemented, making the collision detection more flexible and adaptable.

[0057] In some exemplary embodiments, Figures 1 to 7 As shown, one collision recognition area 112 corresponds to one collision sensor 2 , and the collision sensor 2 is arranged corresponding to the center position or the edge position of the collision recognition area 112 .

[0058] When multiple collision sensors 2 are arranged below the battery chassis 11, a collision sensor 2 may be arranged at the center of each collision recognition area 112. Figure 2 As shown, the six collision sensors 2 can be respectively arranged at the center of the six equally divided collision identification areas 112. The collision sensor 2 is arranged at the center of the collision identification area 112. By comparing the results detected by the collision sensor 2, it is possible to know which collision identification area 112 has a collision, thereby simplifying the algorithm. It should be understood that when multiple collision sensors 2 are arranged below the battery chassis 11, each collision sensor 2 can also be arranged at the edge of each collision identification area 112, such as Figure 3 shown.

[0059] When multiple collision sensors 2 are arranged on the inner bottom surface 121 of the battery pack, since the middle area inside the battery pack 12 is occupied, multiple collision sensors 2 can be arranged at the edge position of the inner bottom surface 121 of the battery pack, and the projection of each collision sensor 2 on the battery chassis 11 can be located at the edge position of each collision identification area 112, such as Figure 3 shown.

[0060] When multiple collision sensors 2 are arranged on the side of the battery pack 12, the multiple collision sensors 2 can be arranged along the inner wall 122 or the outer wall 123, and the projection of each collision sensor 2 on the battery chassis 11 can be located at the edge of each collision identification area 112, such as Figure 4 shown.

[0061] The plurality of collision sensors 2 are preferably arranged at equal intervals, but may also be arranged at unequal intervals, for example, due to space structure limitations. Depending on the number of collision identification areas 112, a plurality of collision sensors 2 may be provided correspondingly, such as 4, 6, or other numbers. The more collision sensors 2 there are, the higher the accuracy of detecting the collision position and the collision intensity, but at the same time the cost will also increase, so the number of collision sensors 2 should be reasonably set.

[0062] In some other exemplary embodiments, one collision identification area 112 corresponds to multiple collision sensors 2. By making one collision identification area 112 correspond to multiple collision sensors 2, the accuracy and redundancy of data collection can be increased, and the comprehensiveness and reliability of detection can be improved. The multiple collision sensors 2 corresponding to each collision identification area 112 are preferably arranged at equal intervals so as to evenly cover the collision identification area 112. Of course, the multiple collision sensors 2 corresponding to the same collision identification area 112 can also be arranged at unequal intervals.

[0063] In some exemplary embodiments, Fig.10 , Fig.11 As shown, the collision sensor 2 is mounted on the circuit board 3, and the collision sensor 2 is configured to communicate with the collision controller 5 (see Figure 20-23 )Electrical connection.

[0064] The collision sensor 2 can be integrated on the circuit board 3. The circuit board 3 can serve as a carrier and also has the functions of transmitting electrical signals and outputting lead points. The circuit board 3 can be a hard circuit board, an FPC board, etc. The circuit board 3 can be electrically connected to the collision controller 5 through the wire 7 in the form of a card lead; an electrical connector 6 (such as a card connector) can also be provided on the circuit board 3, and the electrical connector 6 can be electrically connected to the collision controller 5 through a wire to realize the electrical connection between the collision sensor 2 and the collision controller 5. In addition, if Fig. 9 , Fig. 20 and Fig.23 As shown, the collision sensor 2 may also be directly electrically connected to the collision controller 5 via the wire 7 without being mounted on the circuit board 3 .

[0065] Or, if Fig.13 As shown, the collision sensor 2 is mounted on the circuit board 3, and a packaging structure 4 is provided outside the collision sensor 2 and the circuit board 3. The integrated collision sensor 2 and the circuit board 3 can be packaged in any form, and can be packaged by injection molding, glue pouring, etc. The packaging material can play a protective and insulating role after curing. Or, as Fig.15As shown, an electrical connector 6 may be installed outside the packaging structure 4, and the electrical connector 6 is configured to be electrically connected to the collision controller 5. A wire 7 led out from the collision sensor 2 or the circuit board 3 may be electrically connected to the collision controller 5 via the electrical connector 6 on the packaging structure 4.

[0066] Or, if Fig.12 As shown, the collision sensor 2 is provided with a packaging structure 4, and the packaging form is not limited, as described above. The collision sensor 2 is packaged separately and is electrically connected to the collision controller 5 through a wire 7. Or, as Fig.14 As shown, an electrical connector 6 is installed outside the packaging structure 4 , and the wire 7 led out from the collision sensor 2 can be electrically connected to the collision controller 5 via the electrical connector 6 on the packaging structure 4 .

[0067] Or, if Fig.21 and Fig.23 As shown, the collision sensor 2 can be electrically connected to the electrical connection structure (such as FPC, etc.) 16 of the battery pack 12, and the electrical connection structure is configured to be electrically connected to the collision controller 5. At this time, the collision sensor 2 can be installed on the bottom or side of the battery pack 12.

[0068] In some exemplary embodiments, Fig.16 As shown, the collision sensor 2 can be fixed by bonding. This fixing method can be achieved by using a specific adhesive 10 (such as double-sided tape or glue) to firmly bond the bottom surface of the collision sensor 2 to the battery mounting portion 111 of the battery chassis 11 or the battery pack 12.

[0069] Or, if Fig.17 As shown, the collision sensor 2 can be fastened and fixed by fasteners 13. Both sides of the collision sensor 2 can be provided with protrusions 21, and metal fasteners 13 such as screws, nuts, bolts, etc. are passed through the mounting holes on the protrusions 21 to be fixed to the battery mounting portion 111 of the battery chassis 11 or the battery pack 12.

[0070] Or, if Fig.18 As shown, the collision sensor 2 can be fixed by snapping. The collision sensor 2 can be provided with protrusions 21 on both sides, and the battery mounting portion 111 or the battery pack 12 can be provided with snap fasteners 14, which are snapped to the protrusions 21 on both sides of the collision sensor 2.

[0071] Or, if Fig.19 As shown, the collision sensor 2 can be fixed by pressing the pressure strip 15. This fixing method usually uses the pressure strip 15 provided on the battery mounting portion 111 or the battery pack 12 to fix the collision sensor 2 on the battery mounting portion 111 or the battery pack 12 by applying pressure.

[0072] In some exemplary embodiments, Figure 20 to Figure 23As shown, the collision sensor 2 is an elastic wave sensor, and the collision controller 5 is an elastic wave controller. The elastic wave sensor can be implemented using an existing piezoelectric sensor. The elastic wave sensor has the characteristics of high sensitivity, good response, and strong signal. The elastic wave sensor can effectively avoid the interference of vehicle vibration on the collision detection of the battery chassis 11, and the accuracy is higher.

[0073] like Fig. 22 and Fig.23 As shown, the collision controller 5 can be integrated into the battery detection management system or the domain control 9 of the vehicle. Integrating the collision controller 5 into the battery detection management system allows the collision controller 5 to utilize the existing sensors and data processing capabilities in the battery detection management system to obtain collision data more quickly and respond quickly. In addition, integrating the collision controller 5 into the domain control can achieve centralized control and monitoring of the entire vehicle system, so that the collision controller 5 can work better with other vehicle systems (such as the braking system).

[0074] Of course, in addition to being integrated into the battery detection management system or the domain control 9, the collision controller 5 can also be independently configured, such as Fig.21 and Fig. 22 The collision controller 5 can independently complete the collision detection and processing functions.

[0075] In some exemplary embodiments, Figure 2 As shown, the battery chassis 11 may further include a fixing portion 114 , which may be disposed at an edge of the battery mounting portion 111 and may be used to fix the battery device 100 to the vehicle.

[0076] The embodiment of the present application provides a vehicle, including the battery device 100 with collision detection function described in any of the above embodiments. By performing collision detection, protective measures can be taken in time before serious damage is caused to the battery of the vehicle.
