[0054] Figure 1 The structure schematic diagram of the automobile luggage compartment impact platform simulation device of one embodiment of the present application is shown. As shown in the figure, the automobile luggage compartment impact platform simulation device 100 mainly comprises a frame part 101, a lifting mechanism 102, two rotary adjusters 103 and an adjusting platform 104.

[0055] The frame part 101 is the base support structure of the whole simulation device 100, mainly composed of a bottom plate 105, a stand column 106 and a top plate 107. The bottom plate 105 and the top plate 107 are fixed by the stand column 106. The bottom plate 105 is the bottom support of the simulation device 100, the stand column 106 plays a vertical support role, and the top plate 107 is opposite to the bottom plate 105, which together constitute a stable frame structure.

[0056] The lifting mechanism 102 includes a motor 108, two screw rods 109 and two lifting side plates 110. The two screw rods 109 are vertically and symmetrically arranged on both sides of the frame part 101. The two lifting side plates 110 are respectively threadedly connected with the two screw rods 109. The motor 108 is used to drive the screw rod 109 to rotate to make the two lifting side plates 110 synchronously lift. The motor 108 provides the power required to drive the screw rod 109 to rotate. By precisely controlling the operation of the motor 108, the rotation speed and direction of the screw rod 109 can be controlled, and then the lifting speed and direction of the lifting side plate 110 can be precisely adjusted, so that the lifting side plate 110 reaches the specified height, meeting the requirements of different tests on the height of the adjusting platform 104.

[0057] The two rotary adjusters 103 are respectively and symmetrically arranged on the two lifting side plates 110. The rotary adjuster 103 can rotate relative to the lifting side plate 110. The two ends of the adjusting platform 104 are respectively fixed on the two rotary adjusters 103, and the rotary adjuster 103 can drive the adjusting platform 104 to rotate by a set angle. The rotary adjuster 103 is mainly used to adjust the pitch angle of the adjusting platform 104. Specifically, the rotary adjuster 103 can rotate relative to the lifting side plate 110, and through this rotation, it can drive the adjusting platform 104 fixed at its two ends to rotate, thereby realizing the change of the pitch angle of the adjusting platform 104. This design enables the adjusting platform 104 to simulate the posture of the automobile trunk during the collision process at different angles, providing the possibility for more comprehensive and accurate impact tests. The rotary adjuster 103 can accurately control the set angle of the rotation of the adjusting platform 104, meet the accurate requirements of different test standards and actual working conditions on the angle of the adjusting platform 104, and ensure the reliability and repeatability of the test results. The adjusting platform 104 provides a stable fixed plane for the automobile trunk, ensuring that the automobile trunk can be firmly installed on the simulation device 100 during the test process and will not be loose or displaced due to impact or posture adjustment, ensuring the smooth progress of the test.

[0058] It is easy to understand that the height adjustment is realized by driving the lifting side plates 110 through the lifting mechanism 102, and the pitch angle adjustment is realized by driving the rotation of the rotation adjuster 103, so that the adjustment platform 104 can conveniently adjust the posture of the trunk of the automobile. The multi-dimensional posture adjustment function makes the simulation device 100 be able to more realistically simulate various postures of the trunk of the automobile that may occur in actual collisions, thereby providing a more accurate simulation environment for the impact test of the trunk of the automobile, and helping to more effectively evaluate the protection safety of the trunk area of the automobile to the passengers in the collision.

[0059] In some examples, the lifting mechanism 102 further comprises a sliding rail 111 and a sliding block 112. The bottom of the sliding rail 111 is fixed on the bottom plate 105, and the top is fixed on the top plate 107. The sliding rail 111 is vertically arranged. The sliding block 112 is fixed on the lifting side plate 110, and the sliding rail 111 and the sliding block 112 are in sliding cooperation. In the process of driving the lifting side plate 110 to adjust the height by the lifting mechanism 102, the sliding block 112 moves in the length direction of the sliding rail 111, further enhancing the stability of the operation of the lifting mechanism 102, and effectively reducing the shaking and deviation in the lifting process, ensuring the accuracy and reliability of the adjustment platform 104 in height adjustment. Preferably, after the adjustment platform 104 is smoothly adjusted to the predetermined test height, in order to ensure the stability of the entire device during the test, the lifting side plate 110 can be firmly fixed on the sliding rail 111 by bolts at this time. In this way, it can effectively prevent the lifting side plate 110 from moving accidentally due to various external forces during the test, so as to ensure that the adjustment platform 104 always maintains at the predetermined test height, and provides a stable and reliable test environment for the impact test of the trunk of the automobile,

[0060] In some examples, the lifting mechanism 102 further comprises a transmission rod 113 and two connecting seats 114. The two connecting seats 114 are fixed on the top plate 107, the top of the two screw rods 109 passes through the top plate 107 and is connected to the connecting seats 114, and the two ends of the transmission rod 113 are matched with the two connecting seats 114 respectively. The transmission rod 113 is used for synchronizing the rotation speed of the two screw rods 109. When one of the screw rods 109 is driven to rotate by the motor 108, through the cooperation of the transmission rod 113 and the connecting seat 114, the power can be quickly and accurately transmitted to the other screw rod 109, ensuring that the two screw rods 109 rotate at the same speed. In this way, the two lifting side plates 110 that are threadedly matched with the two screw rods 109 can realize synchronous lifting, ensuring that the adjustment platform 104 always maintains a horizontal state during the lifting process, greatly improving the stability and accuracy of the height adjustment of the adjustment platform 104, and providing a strong guarantee for the reliable operation of the impact platform simulation device 100 for the trunk of the automobile.

[0061] In some examples, the lifting mechanism 102 further comprises a belt pulley set 115. The motor 108 drives a screw rod 109 to rotate through the belt pulley set 115. Specifically, the motor 108 can be welded to the frame part 101, for example, to the bottom plate 105 or the stand column 106. The belt pulley set 115 generally comprises two belt pulleys and a belt connecting the two belt pulleys. The output shaft of the motor 108 is connected to one belt pulley, and the belt pulley is connected to the other belt pulley connected to the screw rod 109 through the belt. When the motor 108 is started, its output shaft drives the belt pulley connected to it to rotate, and through the transmission of the belt, the belt pulley connected to the screw rod 109 is driven to rotate, and in turn the screw rod 109 is driven to rotate. This transmission through the belt pulley set 115 not only enables efficient transmission of the power of the motor 108, but also has certain advantages. For example, the transmission of the belt pulley set 115 can to some extent buffer the impact generated when the motor 108 starts and runs, protect the motor 108 and the screw rod 109 and other components, and prolong their service life; at the same time, the transmission of the belt pulley set 115 can also adjust the rotation speed by selecting belt pulleys of different diameters according to actual needs, provide more flexibility and adjustability for the operation of the lifting mechanism 102, and ensure that the entire lifting mechanism 102 can more accurately and efficiently meet the needs of adjusting the height of the adjustment platform 104 in different test scenarios.

[0062] In some examples, the lifting mechanism 102 further comprises a manual adjuster 116. The manual adjuster 116 is arranged on the connecting seat 114, and is used for manually adjusting to rotate the screw rod 109. The function of the manual adjuster 116 is to allow the operator to manually adjust the rotation of the screw rod 109 in certain situations. In some special scenarios, such as when the motor 108 fails to normally provide power, or when more precise manual fine adjustment of the screw rod 109 is required during the test, the manual adjuster 116 can play a key role. The operator can directly operate the manual adjuster 116, and through a specific mechanical structure, the manual force is transmitted to the screw rod 109 to realize the rotation of the screw rod 109, and in turn drive the lifting side plate 110 and the adjustment platform 104 to adjust the height. The setting of the manual adjuster 116 not only provides a backup adjustment means for the operation of the device, ensures that the test can continue in unexpected situations, but also gives the operator more operation autonomy, meets the diversified needs of adjustment accuracy and method in different test scenarios, and further improves the practicality and reliability of the automobile luggage compartment impact platform simulation device 100.

[0063] In some examples, the impact platform simulation device 100 further comprises a controller 117. The controller 117 is connected with the motor 108, and the controller 117 is used to control the action of the motor 108. The controller 117 is used to accurately control the action of the motor 108. The controller 117 can send corresponding instruction signals to the motor 108 according to the specific requirements of the test through the built-in control program and algorithm. For example, before the test starts, the operator can set the height required by the adjustment platform 104 according to the preset test scheme by pressing the button on the controller 117, and then use the manual adjuster 116 to realize more accurate adjustment of the platform height, so that the adjustment is convenient and accurate.

[0064] In some examples, the impact platform simulation device 100 further comprises a first screw. An arc-shaped slot 118 is formed on the lifting side plate 110, and a long slot 119 is formed on the rotary adjuster 103. The arc-shaped slot 118 corresponds to the long slot 119, the first screw is inserted into the long slot 119 and cooperates with the arc-shaped slot 118 to fix the rotary adjuster 103 and the lifting side plate 110. Because the long slot 119 provides a certain longitudinal movement space, and the arc-shaped slot 118 is designed with an arc, the rotary adjuster 103 can flexibly adjust the position and angle within a certain range. When the rotary adjuster 103 is adjusted to the appropriate position, the first screw is tightened to cooperate with the arc-shaped slot 118, so as to stably fix the rotary adjuster 103 on the lifting side plate 110.

[0065] In some examples, the impact platform simulation device 100 further comprises a second screw. A plurality of fixing holes are formed on the lifting side plate 110 along the length direction of the rotary adjuster 103, and a plurality of mounting holes are provided on the rotary adjuster 103. The second screw is inserted into the mounting hole and cooperates with the fixing hole to fix the rotary adjuster 103 and the lifting side plate 110. That is, the rotary adjuster 103 can move within a range along the length direction within the range of the plurality of fixing holes and the mounting holes. The design of the plurality of fixing holes and the mounting holes gives the rotary adjuster 103 unique adjustment flexibility. The rotary adjuster 103 can move within a certain range along the length direction within the range defined by the fixing holes and the mounting holes. This mobility allows the operator to accurately adjust the position of the rotary adjuster 103 according to actual needs when performing the automobile trunk impact test. For example, when simulating the trunk impact scene under different vehicle models or different test conditions, the position of the rotary adjuster 103 is flexibly changed to adjust the angle and position of the adjustment platform 104, so that the simulation device 100 can more accurately restore the actual situation and provide more reliable data support for the test.

[0066] In some examples, the automobile trunk impact platform simulation device 100 further comprises an X-shaped reinforcing plate 120. The ends of the X-shaped reinforcing plate 120 are fixed on the two parallel columns 106 respectively. The X-shaped reinforcing plate 120 can reinforce the two parallel columns 106. During the automobile trunk impact test, a single column 106 will bear forces from different directions, and the single column 106 may shake or deform when facing complex external forces, affecting the accuracy of the test and the safety of the device. The X-shaped reinforcing plate 120 can evenly distribute the force to the two columns 106, effectively enhancing the mutual support force between the two columns 106, greatly improving the anti-deformation ability of the column 106. This structural design enables the two parallel columns 106 to maintain a stable relative position when bearing a large external force, ensuring that the simulation device 100 does not produce errors due to the instability of the column 106 during the test process, and providing a more reliable simulation environment for the automobile trunk impact test.

[0067] It is obvious to those skilled in the art that various modifications and variations can be made to the above exemplary embodiments of the present application without departing from the spirit and scope of the present application. Therefore, it is intended that the present application cover modifications and variations of the present application provided they come within the scope of the appended claims and their equivalents.
