Description

Technical Field

[0001] The present invention relates to the technical field of battery pack detection, and in particular to a vehicle-mounted battery pack collision detection device. Background Art

[0002] With the widespread use of new energy vehicles, the safety of on-board battery packs is becoming increasingly important. Battery packs are usually installed at the bottom of the vehicle and may be subject to various collisions during driving, thus posing safety risks. Therefore, collision testing of on-board battery packs to evaluate their safety performance under different collision conditions is a key step in ensuring the safe operation of new energy vehicles.

[0003] In the prior art, a vehicle-mounted battery pack collision detection device detects the compressive performance of the battery pack bottom when it is impacted by directly impacting or squeezing the battery pack bottom by setting a fixed impact head.

[0004] However, vehicles may encounter various complex collision situations during actual driving, and the above-mentioned detection method can simulate fewer collision scenarios, resulting in limited accuracy and reliability of the detection results. Summary of the Invention

[0005] The object of the present invention is to provide a vehicle-mounted battery pack collision detection device that can simulate various collision situations of the battery pack during vehicle driving, which is conducive to improving the accuracy and reliability of the battery pack collision detection results.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] A vehicle-mounted battery pack collision detection device comprises: a fixed bracket; a fixed seat, the fixed seat being at least partially rotatably disposed on the fixed bracket, the fixed seat being used to fix the vehicle, and the fixed seat being provided with an avoidance groove extending along a first direction; an impact assembly, the impact assembly being slidably connected to the fixed bracket along the first direction, and the impact assembly being located on a side of the fixed seat facing away from the vehicle, the impact assembly passing through the avoidance groove to strike the battery pack of the vehicle.

[0008] According to the above technical means, the avoidance groove provides a flexible moving space for the impact assembly, and the fixing seat is at least partially rotatable relative to the fixing bracket, so that the angle between the battery pack at the bottom of the vehicle and the impact assembly can be flexibly adjusted. At the same time, the impact assembly can also slide along the first direction, and the relative position between the impact assembly and the bottom of the vehicle can be adjusted, so that the battery pack can be impacted from different angles and directions. It can more comprehensively simulate various collision scenarios that the vehicle may encounter during actual driving, which is conducive to improving the coverage and accuracy of battery pack collision detection, thereby more accurately evaluating the safety performance of the battery pack in various complex collision situations, providing a more reliable basis for the design and improvement of vehicle battery packs, and helping to improve the safety and reliability of the vehicle.

[0009] In one possible implementation, the impact assembly includes a first sliding rod, a mounting seat and an impact head; the first sliding rod is slidably connected to the fixed bracket, the mounting seat is fixed on the first sliding rod, and the mounting seat corresponds to the avoidance groove, and the impact head is detachably connected to the mounting seat.

[0010] According to the above technical means, the first sliding rod is slidably connected to the fixed bracket, providing precise guidance for the impact assembly, ensuring that the impact head can move smoothly and accurately along the preset direction, thereby ensuring that the position and force of each impact can meet the expected requirements, which is conducive to improving the accuracy and consistency of collision detection. The mounting seat corresponds to the avoidance groove to ensure that the impact head can accurately align with the designated position of the battery pack within the range of the avoidance groove for impact. This not only improves the positioning accuracy of the impact head, but also enables the on-board battery pack collision detection device to adapt to battery packs of different sizes and shapes, which is conducive to enhancing the versatility of the on-board battery pack collision detection device and meeting the collision detection needs of battery packs of various vehicle models. The impact head is detachably connected to the mounting seat, which is conducive to improving the flexibility and scalability of the on-board battery pack collision detection device. Impact heads of different shapes, sizes or materials can be quickly replaced according to different test requirements and battery pack types, thereby simulating more diverse collision scenarios and impact conditions.

[0011] In one possible implementation, a first sliding groove extending along a first direction is provided on the fixed bracket; the first sliding rod extends along a second direction, and the end of the first sliding rod slides in cooperation with the first sliding groove; the first direction is perpendicular to the second direction.

[0012] According to the above technical means, the first slide bar is slidably connected to the fixed bracket through the first slide groove. The first slide groove guides the first slide bar, thereby ensuring that the first slide bar can drive the impact head to slide along the first direction. The two ends of the first slide bar are respectively slidably cooperated with the first slide grooves on both sides of the fixed bracket along the second direction, which is also conducive to ensuring the stability of the sliding of the first slide bar, thereby improving the impact accuracy of the vehicle-mounted battery pack collision detection device.

[0013] In a possible implementation, the impact assembly further includes a limiting member; and an end portion of the first sliding rod passes through the first sliding groove and is connected to the limiting member.

[0014] According to the above technical means, the limiter can limit the movement of the first slide bar along the second direction, which is beneficial to improving the accuracy of the moving path of the impact head and ensuring that the impact head always moves along the first direction. At the same time, the limiter also provides additional safety protection for the impact assembly, which can prevent the first slide bar from disengaging from the slide groove, which is beneficial to improving the stability of the impact assembly and thereby improving the reliability of the vehicle-mounted battery pack collision detection device.

[0015] In a possible implementation, the impact head is made of one of stainless steel, carbon steel, and copper.

[0016] According to the above technical means, scenarios in which different objects impact the battery pack can be simulated, thereby simulating more diverse collision scenarios and impact conditions.

[0017] In a possible implementation, the fixing seat includes two supporting components; the two supporting components are spaced apart along the second direction, and the gap between the two supporting components forms the avoidance groove.

[0018] According to the above technical means, the two support assemblies correspond exactly to the wheels on the left and right sides of the vehicle, thereby providing a stable platform for the vehicle and ensuring the stability of the vehicle fixed on the fixed seat. In addition, an avoidance groove is formed between the two support assemblies, thereby exposing the battery pack at the bottom of the vehicle so that the impact head can pass through the avoidance groove to impact the battery pack, providing sufficient collision space for the impact head, making the impact head more flexible, which is conducive to enriching the collision scenarios simulated by the on-board battery pack collision detection device.

[0019] In one possible implementation, the fixed seat also includes a rotating shaft, and the support assembly includes a movable plate and a first buffer plate; the movable plate is used to place the vehicle, and one end of the movable plate along the first direction is rotatably connected to the rotating shaft, and the rotating shaft is fixedly connected to the fixed bracket; the first buffer plate is fixedly connected to the fixed bracket, and the first buffer plate is fixedly connected to the rotating shaft.

[0020] According to the above technical means, the first buffer plate can be set to be parallel to the working platform of the vehicle-mounted battery pack collision detection device. When the vehicle's battery pack is tested, it can be pushed to the movable plate through the first buffer plate, which is conducive to saving the manpower and time required for fixing the vehicle, thereby improving the detection efficiency of the battery pack.

[0021] In one possible implementation, the fixed seat also includes a second sliding rod, and the fixed bracket is provided with a second sliding groove; the other end of the movable plate along the first direction is rotatably connected to the second sliding rod, and the second sliding rod is slidably matched with the second sliding groove; the second sliding groove is an arc-shaped groove, and the arc-shaped groove has the rotating shaft as the center.

[0022] According to the above technical means, the second slide groove ensures that the second slide bar always moves in a circular motion around the rotating axis during the sliding process, thereby driving the movable plate to rotate smoothly. This helps to ensure that the vehicle's position remains accurate during the movable plate's rotation, avoiding deviation or shaking, thereby improving the accuracy of the detection results of the on-board battery pack detection device. The arc groove also has a certain guiding effect. As the second slide bar slides along the second slide groove, the second slide groove can guide the second slide bar to maintain the correct motion trajectory, preventing it from deviating or getting stuck during rotation.

[0023] In one possible implementation, the support assembly further includes a second buffer plate; the second buffer plate is fixedly connected to the second sliding rod, and the second buffer plate is parallel to the first buffer plate.

[0024] According to the above-mentioned technical means, on the one hand, the second buffer plate acts as a limiter, preventing the vehicle on the movable plate from deflecting in the first direction, thereby improving the accuracy of the detection results of the on-board battery pack collision detection device. On the other hand, the second buffer plate provides additional buffering protection for the rotation of the movable plate. During the rotation of the movable plate, especially when approaching the extreme position, the second buffer plate can cooperate with the first buffer plate to effectively absorb and mitigate the impact force that may occur during the rotation process, thereby preventing accidental damage to the vehicle or battery pack caused by excessive rotation of the movable plate. At the same time, it also protects the structural components of the on-board battery pack collision detection device itself, which helps to extend the service life of the on-board battery pack collision detection device.

[0025] In a possible implementation, a driving member is further included, and the driving member is configured to drive the movable plate to rotate relative to the fixed bracket; and / or drive the impact assembly to slide along the first direction relative to the fixed bracket.

[0026] According to the above technical means, the movement of the impact assembly and the fixed seat is driven by the driving member, which is conducive to improving the degree of automation and detection efficiency of the vehicle-mounted battery pack collision detection device. The driving member can more accurately control the rotation angle of the movable plate and the position of the impact assembly and the speed and path of dynamic movement, thereby ensuring that when the same collision situation is simulated multiple times, the conditions of each simulation remain consistent, which is conducive to improving the repeatability and reliability of the detection results.

[0027] Beneficial effects of the present invention:

[0028] (1) The vehicle-mounted battery pack collision detection device of the present application can flexibly adjust the angle of the vehicle to be detected and the position of the impact component, so as to more comprehensively simulate the different collision conditions encountered by the vehicle during actual driving, which is conducive to improving the reliability of the detection results of the vehicle-mounted battery pack collision detection device.

[0029] (2) The impact head of the present application is detachably connected to the mounting base, and the impact head of different materials and shapes can be quickly replaced according to the detection needs, which is conducive to further enriching the collision scenarios simulated by the vehicle-mounted battery pack collision detection device.

[0052] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0053] In response to the technical problems raised in the background technology, an embodiment of the present application provides a vehicle-mounted battery pack collision detection device, including a fixed bracket, a fixed seat and an impact assembly. The fixed seat is used to fix the vehicle and is at least partially rotatable on the fixed bracket. The impact assembly is arranged under the fixed bracket and passes through the avoidance groove on the fixed bracket to impact the battery pack. At the same time, the impact assembly can slide relative to the fixed bracket. The avoidance groove provides a flexible movement space for the impact assembly. At the same time, the fixed seat is at least partially rotatable relative to the fixed bracket, so that the angle between the battery pack at the bottom of the vehicle and the impact assembly can be flexibly adjusted. At the same time, the impact assembly can also slide along a first direction, and the relative position between the impact assembly and the bottom of the vehicle can be adjusted, so that the battery pack can be impacted from different angles and directions. It can more comprehensively simulate various collision scenarios that the vehicle may encounter during actual driving, which is conducive to improving the coverage and accuracy of battery pack collision detection, thereby more accurately evaluating the safety performance of the battery pack in various complex collision situations, providing a more reliable basis for the design and improvement of vehicle battery packs, and is conducive to improving the safety and reliability of the vehicle.

[0054] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The following embodiments of the present application are described in conjunction with the accompanying drawings:

[0055] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the vehicle-mounted battery pack collision detection device 100 of an embodiment of the present application includes a fixed bracket 110, a fixed seat 120 and an impact assembly 130, wherein the fixed seat 120 is at least partially rotatably arranged on the fixed bracket 110, the fixed seat 120 is used to fix the vehicle, and an avoidance groove 122 extending along a first direction is provided on the fixed seat 120; the impact assembly 130 is slidably connected to the fixed bracket 110 along the first direction, and the impact assembly 130 is located on the side of the fixed seat 120 away from the vehicle, and the impact assembly 130 passes through the avoidance groove 122 to hit the battery pack of the vehicle. Figure 1 The X direction is the first direction, and the Y direction is the second direction.

[0056] In the embodiment of the present application, the avoidance groove 122 provides a flexible moving space for the impact assembly 130, and the fixing seat 120 is at least partially rotatable relative to the fixing bracket 110, so that the angle between the battery pack at the bottom of the vehicle and the impact assembly 130 can be flexibly adjusted. At the same time, the impact assembly 130 can also slide along the first direction, and the relative position between the impact assembly 130 and the bottom of the vehicle can be adjusted, so that the battery pack can be impacted from different angles and directions, which can more comprehensively simulate various collision scenarios that the vehicle may encounter during actual driving, which is conducive to improving the coverage and accuracy of battery pack collision detection, thereby more accurately evaluating the safety performance of the battery pack in various complex collision situations, providing a more reliable basis for the design and improvement of vehicle battery packs, and helping to improve the safety and reliability of the vehicle.

[0057] The first avoidance groove 122 extends along a first direction, and the impact assembly 130 slides along the first direction, allowing it to be adjusted to different impact positions. Since the battery pack is not only subject to direct impact during vehicle operation, but may also scrape against obstacles on the ground, this embodiment of the present application allows the impact assembly 130 to impact the battery pack while simultaneously moving along the first direction, thereby simulating a scrape between the vehicle and obstacles on the ground during operation. Furthermore, the mounting base 120 can simultaneously adjust the vehicle to different tilt angles, allowing the impact assembly 130 to impact the battery pack, thereby simulating the battery pack being impacted while the vehicle is traveling on an uneven road surface.

[0058] Therefore, the vehicle-mounted battery pack collision detection device 100 provided in the embodiment of the present application can not only simulate the situation where the battery pack is subjected to direct collision when the vehicle is stationary, but also simulate the situation where the battery pack is subjected to dynamic impact while the vehicle is driving. Compared with the prior art that hits the battery pack through a fixed impact device, the vehicle-mounted battery pack collision detection device 100 in the embodiment of the present application can more comprehensively simulate the complex scenarios of the vehicle being hit, which is conducive to improving the accuracy of the battery pack collision detection results, thereby improving the safety performance of the battery pack, and improving the safety and reliability of the vehicle.

[0059] In some possible implementations, see Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the impact assembly 130 of the embodiment of the present application includes a first slide rod 131, a mounting seat 132 and an impact head 133; the first slide rod 131 is slidably connected to the fixed bracket 110, the mounting seat 132 is fixed on the first slide rod 131, and the mounting seat 132 corresponds to the avoidance groove 122, and the impact head 133 is detachably connected to the mounting seat 132.

[0060] In a specific implementation, the first slide bar 131 is slidably connected to the fixed bracket 110, providing precise guidance for the impact assembly 130, ensuring that the impact head 133 can move smoothly and accurately along the preset direction, thereby ensuring that the position and force of each impact can meet the expected requirements, which is beneficial to improving the accuracy and consistency of collision detection. The mounting seat 132 corresponds to the avoidance groove 122 to ensure that the impact head 133 can accurately align with the designated position of the battery pack within the range of the avoidance groove 122 for impact. This not only improves the positioning accuracy of the impact head 133, but also enables the vehicle-mounted battery pack collision detection device 100 to adapt to battery packs of different sizes and shapes, which is beneficial to enhancing the versatility of the vehicle-mounted battery pack collision detection device 100 and meeting the collision detection needs of battery packs of various vehicle models.

[0061] Furthermore, the impact head 133 is detachably connected to the mounting base 132, which is beneficial to improving the flexibility and scalability of the vehicle-mounted battery pack collision detection device 100. The impact head 133 of different shapes, sizes or materials can be quickly replaced according to different test requirements and battery pack types, thereby simulating more diverse collision scenarios and impact conditions. For example, Figure 1 As shown, the impact head 133 can be a sharp cone to simulate the situation where a sharp object hits the battery pack, or, as shown in FIG. Figure 2As shown, the impact head 133 can be a horizontally arranged prism to simulate the wide-area impact of a vehicle collision. Alternatively, the impact head 133 can be spherical or have other irregular shapes. The material of the impact head 133 can be selected from stainless steel, carbon steel, copper, etc. to simulate the impact of different objects on the battery pack. Of course, the embodiment of the present application does not limit the shape and material of the impact head 133, and it can be changed according to the collision scenario to be simulated.

[0062] In addition, the mounting base 132 can be a pin, which has a simple and compact structure, which helps to reduce the volume of the impact assembly 130 and improve the flexibility of the impact head 133. At the same time, the fixation of the pin to the first slide bar 131 and the detachable connection of the impact head 133 are both highly stable, which helps to ensure that the impact head 133 will not loosen or shift during the simulated collision, thereby ensuring the accuracy and reliability of the vehicle battery pack collision detection device 100. Of course, the specific structure of the mounting base 132 is not limited in the embodiment of the present application, and it only needs to be able to stably connect with the first slide bar 131 and the impact head 133.

[0063] This detachable connection method not only facilitates the replacement and maintenance of the impact head 133 and saves detection costs, but also helps to expand the application scope of the vehicle-mounted battery pack collision detection device 100, enabling it to better adapt to the diverse detection needs of vehicle-mounted battery packs and provide strong support for the comprehensive evaluation of the battery pack's safety performance.

[0064] In some possible implementations, see Figure 1 、 Figure 3 and Figure 4 As shown, a first slide groove 111 extending along a first direction is provided on the fixed bracket 110 of the embodiment of the present application; a first slide rod 131 extends along a second direction, and an end portion of the first slide rod 131 slides in cooperation with the first slide groove 111; the first direction is perpendicular to the second direction.

[0065] In some embodiments, the first slide bar 131 is slidably connected to the fixed bracket 110 through the first slide groove 111. The first slide groove 111 guides the first slide bar 131, thereby ensuring that the first slide bar 131 can drive the impact head 133 to slide along the first direction. The two ends of the first slide bar 131 respectively slide with the first slide grooves 111 on both sides of the fixed bracket 110 along the second direction, which is also beneficial to ensure the stability of the sliding of the first slide bar 131, thereby improving the impact accuracy of the vehicle-mounted battery pack collision detection device 100.

[0066] In some possible implementations, see Figure 1 、 Figure 3 and Figure 4 As shown, the impact assembly 130 of the embodiment of the present application further includes a limiting member 134 ; the end of the first sliding rod 131 passes through the first sliding groove 111 and is connected to the limiting member 134 .

[0067] It can be understood that the limiter 134 can limit the movement of the first slide bar 131 along the second direction, which is beneficial to improving the accuracy of the moving path of the impact head 133 and ensuring that the impact head 133 always moves along the first direction. At the same time, the limiter 134 also provides additional safety protection for the impact assembly 130, which can prevent the first slide bar 131 from escaping the slide groove, which is beneficial to improving the stability of the impact assembly 130 and thereby improving the reliability of the vehicle-mounted battery pack collision detection device 100.

[0068] In some possible implementations, see Figure 1 、 Figure 3 and Figure 4 As shown, the fixing seat 120 of the embodiment of the present application includes two supporting components 121 ; the two supporting components 121 are spaced apart along the second direction, and the gap between the two supporting components 121 forms an avoidance groove 122 .

[0069] In a specific implementation, the two support components 121 correspond exactly to the wheels on the left and right sides of the vehicle, thereby providing a stable platform for the vehicle and ensuring the stability of the vehicle fixed on the fixing seat 120. In addition, an avoidance groove 122 is formed between the two support components 121, thereby exposing the battery pack at the bottom of the vehicle so that the impact head 133 can pass through the avoidance groove 122 to impact the battery pack, providing sufficient collision space for the impact head 133, making the impact head 133 more flexible, which is conducive to enriching the collision scenarios simulated by the vehicle-mounted battery pack collision detection device 100.

[0070] In some possible implementations, see Figure 1 、 Figure 3 and Figure 4 As shown, the fixed seat 120 of the embodiment of the present application also includes a rotating shaft 123, and the support assembly 121 includes a movable plate 1212 and a first buffer plate 1211; the movable plate 1212 is used to place the vehicle, and one end of the movable plate 1212 along the first direction is rotatably connected to the rotating shaft 123, and the rotating shaft 123 is fixed to the fixed bracket 110; the first buffer plate 1211 is fixed to the fixed bracket 110, and the first buffer plate 1211 is fixed to the rotating shaft 123.

[0071] It should be noted that the first buffer plate 1211 can be set to remain parallel to the working platform of the vehicle-mounted battery pack collision detection device 100. When testing the vehicle's battery pack, it can be pushed onto the movable plate 1212 via the first buffer plate 1211, which helps save manpower and time required to fix the vehicle, thereby improving the efficiency of battery pack testing. In addition, the movable plate 1212 can rotate about the rotation axis 123 relative to the fixed bracket 110, thereby fixing the vehicle at different angles for collision simulation. When the movable plate 1212 is set at an angle, the movable plate 1212 and the first buffer plate 1211 are not on the same plane, thereby preventing the vehicle from sliding off the movable plate 1212 when impacted, or providing a certain buffering effect when the vehicle slides, which helps improve the safety and reliability of the operation of the vehicle-mounted battery pack collision detection device 100.

[0072] In some possible implementations, see Figure 1 、 Figure 3 and Figure 4 As shown, the embodiment of the present application further includes a driving member, which is configured to drive the movable plate 1212 to rotate relative to the fixed bracket 110; and / or drive the impact assembly 130 to slide along the first direction relative to the fixed bracket 110.

[0073] In specific implementation, the movement of the impact assembly 130 and the fixing seat 120 is driven by a driving member, which is beneficial to improving the degree of automation and detection efficiency of the vehicle-mounted battery pack collision detection device 100. The driving member can more accurately control the rotation angle of the movable plate 1212 and the position of the impact assembly 130 and the speed and path of dynamic movement, thereby ensuring that when the same collision situation is simulated multiple times, the conditions of each simulation remain consistent, which is beneficial to improving the repeatability and reliability of the detection results.

[0074] In addition, the setting of the drive component also makes it possible to implement more complex collision test sequences. For example, the battery pack can be impacted from different angles and with different forces in sequence according to a preset program, further enriching the scenarios and content of the collision test, and facilitating a more in-depth study of the safety performance of the battery pack under various extreme conditions.

[0075] The driving part can be a motor, a cylinder, etc., and the embodiment of the present application does not limit this, and a reasonable selection can be made according to actual conditions.

[0076] In some possible implementations, see Figure 1 、 Figure 3 and Figure 4As shown, the fixed seat 120 of the embodiment of the present application also includes a second slide rod 124, and a second slide groove 112 is provided on the fixed bracket 110; the other end of the movable plate 1212 is rotatably connected to the second slide rod 124 along the first direction, and the second slide rod 124 slides in cooperation with the second slide groove 112; the second slide groove 112 is an arc groove, and the arc groove has the rotating shaft 123 as the center.

[0077] In practice, the second slide groove 112 ensures that the second slide bar 124 always moves in a circular motion around the rotation axis 123 during the sliding process, thereby driving the movable plate 1212 to rotate smoothly. This helps ensure that the vehicle's position remains accurate during the rotation of the movable plate 1212, avoiding deviation or shaking, thereby improving the accuracy of the detection results of the on-board battery pack detection device. The arcuate groove also has a certain guiding function. When the second slide bar 124 slides along the second slide groove 112, the second slide groove 112 can guide the second slide bar 124 to always maintain the correct motion trajectory, preventing it from deviating or getting stuck during rotation.

[0078] Furthermore, the sliding cooperation between the second slide bar 124 and the second slide groove 112 provides flexible adjustment capability for the rotation of the movable plate 1212. The driving member can adjust the rotation angle of the fixed seat 120 by driving the second slide bar 124 to move in the second slide groove 112. It is also convenient for staff to judge the inclination angle of the movable plate 1212 by observing the positional relationship between the second slide bar 124 and the second slide groove 112, which is conducive to improving the convenience of using the vehicle-mounted battery pack collision detection device 100.

[0079] In some possible implementations, see Figure 1 、 Figure 3 and Figure 4 As shown, the support assembly 121 of the embodiment of the present application further includes a second buffer plate 1213 ; the second buffer plate 1213 is fixedly connected to the second sliding rod 124 , and the second buffer plate 1213 and the first buffer plate 1211 are parallel to each other.

[0080] It should be noted that the first buffer plate 1211, the movable plate 1212, and the second buffer plate 1213 are arranged sequentially along the first direction. On the one hand, the second buffer plate 1213 acts as a limiter, preventing the vehicle on the movable plate 1212 from deflecting in the first direction, thereby improving the accuracy of the detection results of the vehicle-mounted battery pack collision detection device 100. On the other hand, the second buffer plate 1213 provides additional buffering protection for the rotation of the movable plate 1212. During the rotation of the movable plate 1212, especially when approaching the extreme position, the second buffer plate 1213 can cooperate with the first buffer plate 1211 to effectively absorb and mitigate the impact force that may occur during the rotation process, thereby preventing the movable plate 1212 from causing accidental damage to the vehicle or battery pack due to excessive rotation. At the same time, it also protects the structural components of the vehicle-mounted battery pack collision detection device 100 itself, which is conducive to extending the service life of the vehicle-mounted battery pack collision detection device 100.

[0081] In summary, the embodiment of the present application provides a vehicle-mounted battery pack collision detection device 100, including a fixed bracket 110, a fixed seat 120 and an impact assembly 130, the fixed seat 120 includes a movable plate 1212, the vehicle is fixed on the movable plate 1212, the movable plate 1212 is rotatably arranged on the fixed bracket 110, the impact assembly 130 includes an impact head 133, a mounting seat 132 and a first sliding rod 131, the mounting seat 132 is fixed on the first sliding rod, the impact head 133 is detachably connected to the mounting seat 132, the first sliding rod 131 is slidably connected to the fixed bracket 110, thereby driving the impact head 133 to slide along the first direction.
