[0028] As Figures 1 - 3 shown, the present utility model provides an automobile chassis collision test device.
[0029] In an exemplary embodiment, the automobile chassis collision test device includes:
[0030] A foundation pit 1, in which an installation space 2 is provided;
[0031] A position adjustment component, which is arranged in the installation space 2. The position adjustment component includes a first-direction adjustment component and a second-direction adjustment component;
[0032] A collision device, which is arranged on the position adjustment component. The collision device can move in the first direction and the second direction in the installation space 2 through the position adjustment component. The collision device includes a base 12 and a collision mechanism. The collision mechanism is installed on the base 12, and an angle adjustment mechanism for adjusting the angle of the collision mechanism is provided on the base 12.
[0033] In this embodiment, through the provided position adjustment component, the collision device can be driven to move in two directions within the installation space 2 of the foundation pit 1, freely adjusting the position of the collision device. In cooperation with the angle adjustment mechanism to adjust the inclination angle of the collision mechanism, during the collision, it can conveniently collide with the chassis of the vehicle at a specified angle, simulating a real collision environment and achieving the integrity and accuracy of the test experiment.
[0034] Exemplarily, in this embodiment, the first direction is the X-axis direction (left-right direction), and the second direction is the Y-axis direction (front-back direction), and the X-axis direction is perpendicular to the Y-axis direction. Specifically, the collision device is installed on the second-direction adjustment component. When the second-direction adjustment component works, it can drive the collision device to move in the Y-axis direction, and the second-direction adjustment component is controlled by the first-direction adjustment component to move in the X-axis direction, thus realizing the free movement of the collision device.
[0035] It is worth noting that in this embodiment, the angle of the collision mechanism is adjusted through the angle adjustment mechanism, so that there is a certain included angle between the collision mechanism and the chassis of the vehicle, thereby being able to comprehensively simulate the collision environment and ensuring the accuracy of the experiment.
[0036] In an exemplary embodiment, an installation position 14 is provided on the base 12. The angle adjustment mechanism includes an installation rod 15 and an adjustment motor 13. The installation rod 15 is arranged on the collision mechanism and is rotatably connected to the installation position 14. The adjustment motor 13 is arranged on the base 12, and the output end of the adjustment motor 13 passes through the base 12 and is coaxially connected to the installation rod 15. The adjustment motor 13 can drive the installation rod 15 to rotate and adjust the angle of the collision mechanism.
[0037] In this embodiment, when the adjustment motor 13 works, it can drive the installation rod 15 to rotate, and the installation rod 15 is also installed on the collision mechanism. During the rotation of the installation rod 15, the collision mechanism is synchronously driven to rotate.
[0038] Exemplarily, in this embodiment, through the installation position 14 and the installation rod 15 provided on the base 12, the rotational connection between the collision mechanism and the base 12 is indirectly realized, so as to conveniently adjust the angle of the collision mechanism through the adjustment motor 13.
[0039] Exemplarily, the adjustment motor 13 in this embodiment is a stepping motor, which can realize forward rotation and reverse rotation to control the collision mechanism to tilt left or right.
[0040] It is worth noting that an indicating disk 1202 is provided on the base 12 for indicating the rotation angle of the collision mechanism. The indicating disk 1202 is arranged on the side wall of the base 12. The indicating disk 1202 is fan-shaped, and the middle part of the indicating disk 1202 is vertical. When the collision device is in its original position, the collision device is vertically placed. In this embodiment, an indicating needle can also be correspondingly arranged on the collision mechanism to point to the indicating disk 1202 to clearly indicate the current angle of the collision mechanism.
[0041] The collision mechanism includes a driver 16 and a pushing component. The pushing component is arranged on the base 12. The extending end of the driver 16 can drive the pushing component to move and impact the vehicle chassis. At the same time, the pushing component includes a pushing plate 18 and a punch 19. The punch 19 is installed on the pushing plate 18. A contact surface 1801 is provided on the side of the pushing plate 18 away from the punch 19. The extending end of the driver 16 can contact the contact surface 1801 to drive the pushing plate 18 to move vertically. A guiding rod 17 is also provided on the base 12, and the pushing plate 18 is slidably connected to the guiding rod 17.
[0042] In this embodiment, through the arranged pushing plate 18, when the driver 16 is started, the extending end of the driver 16 will abut against the contact surface 1801 of the pushing plate 18 and move upward. The pushing plate 18 synchronously drives the punch 19 to move upward. Finally, the punch 19 collides with the vehicle chassis to complete the test. During the upward movement of the pushing plate 18, the guiding rod 17 is used for limiting and guiding to ensure the stability of the punch 19 during movement. After the collision is completed, the output end of the driver 16 retracts, and the pushing plate 18 resets under the action of gravity.
[0043] Exemplarily, in this embodiment, the number of guiding rods 17 is two, which are arranged on the base 12. Limit blocks 1701 are provided at the ends of the guiding rods 17 to limit the pushing plate 18 and prevent the pushing plate 18 from coming off.
[0044] Exemplarily, the shape of the punch 19 in this embodiment can be oval, arrow-shaped or other shapes to meet the collision requirements.
[0045] It is worth noting that the punch 19 and the pushing plate 18 in this embodiment can be integrated to achieve high-strength collision, or they can be connected by detachable connection, such as bolts, etc., so as to facilitate the replacement and disassembly of the punch 19.
[0046] In an exemplary embodiment, a buffer 20 is provided on the side of the driver 16 away from the base 12 for buffering the impact force when the pushing plate 18 returns.
[0047] In this embodiment, due to the strong impact force of the driver 16, the punch 19 will generate a large amount of resilience after colliding with the vehicle chassis. Therefore, a buffer member 20 is provided on the driver 16 to prevent the push plate 18 from moving rapidly downward and hitting the driver 16, which may cause damage to the driver 16.
[0048] Exemplarily, in this embodiment, the buffer member 20 is in the form of a support rod and a buffer pad. The support rod is provided on the driver 16, and the buffer pad is provided at the upper end of the support rod to contact the contact surface 1801.
[0049] Exemplarily, the number of the buffer members 20 in this embodiment is four and they are arranged in a square shape to fully contact the push plate 18.
[0050] It should be noted that in this embodiment, other buffer members 20 with buffer functions can also be used to achieve buffering.
[0051] In an exemplary embodiment, the first direction adjustment assembly includes a first driving motor 3 and a first driving screw 4. The first driving motor 3 is provided on the foundation pit 1, the first driving screw 4 is coaxially connected to the output end of the first driving motor 3, and a first nut seat 7 connected to the first driving screw 4 is provided on the base 12. The first driving screw 4 can drive the collision device to move in the first direction.
[0052] In this embodiment, the second direction adjustment assembly is installed on the first nut seat 7, and the collision device is installed on the second direction adjustment assembly. When the first driving screw 4 rotates through the first driving motor 3, the first nut seat 7 cooperating with the first driving screw 4 can move along the axial direction of the first driving screw 4 on the first driving screw 4, thereby driving the collision device to move in the first direction.
[0053] Exemplarily, the first nut seat 7 in this embodiment is a lead screw nut seat, which can be threadedly connected to the first driving screw 4 to achieve axial movement.
[0054] Exemplarily, the second-direction adjustment assembly includes a second driving motor 5 and a second driving screw 6. The second driving motor 5 is disposed on the foundation pit 1, and the second driving screw 6 is coaxially connected to the output end of the second driving motor 5. The second-direction adjustment assembly further includes a second nut seat 9 connected to the second driving screw 6. The base 12 is connected to the second nut seat 9. An installation groove 1201 for installing the second nut seat 9 is formed on the base 12. The second driving screw 6 can drive the first-direction adjustment assembly to move in the second direction. In this embodiment, the second-direction assembly further includes a mounting plate 8. The second driving screw 6 is disposed on the mounting plate 8, and the mounting plate 8 is connected to the first nut seat 7. When the first nut seat 7 moves under the action of the first driving screw 4, the first nut seat 7 drives the mounting plate 8 to move synchronously. And in this embodiment, under the action of the second driving motor 5, the second driving screw 6 can drive the second nut seat 9 to move in the axial direction of the second driving screw 6, so as to realize the function of driving the collision device to move.
[0055] It should be noted that in this embodiment, the first driving motor 3 is fixed, and the second driving motor 5 needs to move on the foundation pit 1 along the first direction. Therefore, an avoidance groove 11 corresponding to the first motor is formed on the foundation pit 1 to avoid movement interference between the first motor and the foundation pit 1 when the first motor moves. At the same time, since the second-direction adjustment assembly needs to move integrally along the first direction, in order to improve the stability of the second-direction adjustment assembly, a guide rail 10 can also be disposed in the installation space 2, wherein the guide rail 10 extends along the first direction, and the mounting plate 8 can slide on the guide rail 10 to improve the stability of the second-direction adjustment assembly.
[0056] It should also be noted that the first driving motor 3 and the second driving motor 5 in this embodiment are both stepper motors, which can realize forward rotation and reverse rotation.
[0057] In an exemplary embodiment, a placement plate 101 is provided on the foundation pit 1. The placement plate 101 is used to place an automobile. There is a collision gap between the placement plates 101. During a collision, the preset collision points on the automobile chassis correspond to the collision gap, and the pushing assembly can extend from the collision gap to collide with the chassis of the automobile.
[0058] In this embodiment, by providing the placement plate 101 on the foundation pit 1, the automobile can be supported and positioned to expose the chassis of the automobile within the collision range. According to different tested automobiles, the placement plate 101 can be replaced to adjust the collision gap, thereby improving the application range of the present utility model.
[0059] Exemplarily, in this embodiment, a positioning mechanism corresponding to the automobile can also be provided on the placement plate 101 to prompt the vehicle to park at a designated place, so as to improve the efficiency of the collision test.
[0060] It should be noted that in the prior art, the vehicle usually needs to be lifted before collision. If the vehicle is in the lifted state by the lift, it is very difficult to handle after thermal runaway. However, in this embodiment, if the test vehicle has a thermal runaway, the runaway vehicle can be directly towed away for handling.
[0061] In an exemplary embodiment, it further includes a control module. The control module includes a controller, and the controller is used to control the position adjustment component to adjust the position of the collision device.
[0062] The control module in this embodiment can be used to control the first direction adjustment component, the second direction adjustment component, the adjustment motor 13, and the driver 16. All driving components are controlled by the controller to achieve remote operation, improve efficiency, and enhance the safety performance of the collision test.
[0063] In summary, by setting the position adjustment component and the angle adjustment mechanism, the present utility model can conveniently adjust the collision angle of the collision mechanism, improve the accuracy of the collision test, and at the same time ensure the safety performance of personnel through remote and intelligent operations on site.
[0064] The above embodiments are only illustrative of the principles and effects of the present utility model, and are not used to limit the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
