The connecting block 8 is provided with a second connecting groove 9, and the design of the second connecting groove 9 provides more flexibility and possibility for the connection of the connecting block 8 with other components. According to the specific requirements of the test, the connecting block 8 can be connected with other auxiliary devices or support structures to further enhance the stability and functionality of the entire test device.

[0027] A second support slope 11 is designed at one end of the fixed seat 1, and a plurality of second support slope fixing members 12 are arranged on the second support slope 11. These fixing members are used to firmly connect the engine to the second support slope. Through this slope support structure, the installation posture of the engine in the actual vehicle can be better simulated, and the results of the collision test are closer to the actual situation. At the same time, the second support slope fixing members 12 can be adjusted according to the shape and size of the engine to ensure that the connection between the engine and the fixed seat is tight and reliable, avoiding loosening or displacement during the collision test, which affects the accuracy and safety of the test.

[0028] A first support slope 10 is also provided on one side of the second support slope 11, and a fixed block 15 is arranged on the first support slope 10. The first support slope 10 cooperates with the second support slope 11 to jointly bear the support of the engine, improving the stability and load-bearing capacity of the entire support structure.

[0029] Example 2: Refer to Figures 1 to 5 An engine collision test device, a fixed seat 1 provides support for an engine 16, and the fixed seat 1 must have sufficient strength and stability to withstand the strong impact force generated during the collision test. The engine 16 is placed on the fixed seat 1, and a collision plate 5 is placed at one end. In order to make the test more flexible and adaptable, a plurality of adjusting base plates 3 are arranged side by side on the fixed seat 1. These adjusting base plates 3 can be precisely adjusted according to the size, shape and expected collision angle of the engine under different test scenarios. One end of the adjusting base plate 3 is designed with a first connecting groove 2, and the fixed seat 1 can rotate freely in the first connecting groove 2. This design allows the installation angle of the engine to be adjusted, whether it is a frontal collision, a side collision or an oblique collision, it can be accurately simulated, making the test results more valuable.

[0030] The other side of the adjusting base plate 3 is ingeniously arranged with an adjusting device 4, and the upper side is closely connected with an adjusting rod 7.

Such design not only ensures the stability of the engine oil rail 17 during the test, but also helps to improve the reliability of the entire engine crash test device and the accuracy of the test data.

[0033] The inner recess 6 is carefully designed below the second supporting slope 11. The shape and size of this inner recess 6 are accurately calculated to meet the specific structural requirements. The side of the inner recess 6 close to the second supporting slope 11 forms a side protrusion 13. The design of the side protrusion 13 not only increases the strength of the structure, but also provides a reference point for the connection and positioning of other components. This design makes the structure of the entire device more compact, and the cooperation between the components more tight, thereby improving the overall stability and carrying capacity of the device.

More ingeniously, the second connecting groove 9 on the connecting block 8 can freely rotate on the side protrusion 13, and this rotating function gives the connecting block 8 great flexibility. During the collision test, this rotatable design can automatically adjust the position and angle of the connecting block 8 according to different force conditions and movement requirements, so as to better adapt to the dynamic changes of the engine and ensure the stability and safety of the engine during the entire test process. Through this delicate design, not only the adaptability and reliability of the device are improved, but also strong support is provided for realizing more accurate collision test.

[0035] Embodiment 3: Reference Figures 1 to 5 An engine collision test device, one end of the engine 16 is equipped with a collision plate 5, which plays the role of simulating a collision object and can generate corresponding collision force when in contact with the engine, so as to detect the structural strength and performance change of the engine under the collision situation. A plurality of adjusting bottom plates 3 are also installed side by side on the fixed seat 1, which can be adjusted in position according to different test requirements. One end of the adjusting bottom plate 3 is provided with a first connecting groove 2, so that the fixed seat 1 can freely rotate in the first connecting groove 2, which gives the flexible adjustment ability of the engine installation angle, so as to more accurately simulate various angle collisions in the actual collision scene. The adjusting bottom plate 3 is also provided with an adjuster 4 on one side, which is connected with an adjusting rod 7 above, and the rotation of the adjuster 4 can drive the adjusting rod 7 to move up and down, thereby realizing fine adjustment of the position of the engine and ensuring the relative position between the engine and the collision plate 5 is accurate, providing strong guarantee for the accuracy of the collision test.

[0036] On the basis of the above structure, the connecting mode between the adjusting rod 7 and the connecting block 8 is further optimized. The adjusting rod 7 and the connecting block 8 are fixedly connected, which enhances the firmness and reliability between the two, so that they can withstand various forces generated during the collision test. The connecting block 8 is also provided with a second connecting groove 9, which provides greater flexibility and possibility for the connection of the connecting block 8 with other components, and can connect the connecting block 8 with other auxiliary devices or supporting structures according to the specific requirements of the test, thereby further improving the stability and functionality of the entire test device.

[0037] One end of the fixing seat 1 is designed as a second support slope 11, and a plurality of second support slope fixing members 12 are arranged on the second support slope 11, which are used to firmly fix the engine on the second support slope. By means of this slope support structure, the installation posture of the engine in the actual vehicle can be more realistically simulated, so that the results of the crash test are more realistic and have reference value. At the same time, the second support slope fixing members 12 can be adjusted according to the different shapes and sizes of the engine, so as to ensure the close and reliable connection between the engine and the fixing seat, effectively avoid the loosening or displacement phenomenon in the process of the crash test, and ensure the accuracy and safety of the test.

[0038] A first support slope 10 is also arranged on one side of the second support slope 11, and a fixing block 15 is arranged on the first support slope 10.

This supporting method is not only stable, but also can accurately transmit the slight movement of the adjusting rod 7 to the fixing seat 1, so as to realize fine adjustment of the position of the engine. In this way, the test personnel can easily adjust the relative position between the engine and the crash plate to simulate different collision scenes, improve the flexibility and accuracy of the test.

[0040] The shape and layout of the adjusting bottom plate 3 are specified in this embodiment. The adjusting bottom plate 3 is designed in a long strip shape, which is conducive to providing sufficient adjustment range in a limited space. At the same time, the spacing between each adjusting bottom plate 3 is kept equal, which ensures the uniformity and consistency of the adjustment. Equal spacing means that when adjusting the position, each adjusting bottom plate 3 has the same effect on the engine, thereby avoiding adjustment errors caused by inconsistent spacing. This evenly distributed adjusting bottom plate 3 not only improves the accuracy of adjustment, but also makes the structure of the entire device more compact and stable.

[0041] The adjusting rods 7 are designed in a cylindrical shape and arranged in parallel. The cylindrical adjusting rods 7 have good mechanical properties and wear resistance, can withstand large forces and torques, and ensure stability and reliability during long-term use. The parallel arrangement design allows multiple adjusting rods 7 to work together to bear the weight and impact force of the engine, improving the carrying capacity and stability of the entire device. This design not only optimizes space utilization, but also enhances the overall performance of the device, making it suitable for engines of different sizes and weights and meeting various testing needs.

[0042] The utility model is not limited to the details of the above exemplary embodiments for those skilled in the art, and can be realized in other specific forms without departing from the spirit or basic characteristics of the utility model.
