[0023] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] like Figure 1 As shown, the shock absorber tower test device of this utility model embodiment includes a fixing component 1 and a loading component 2.

[0025] The fixing assembly 1 includes a fixing base 11 and multiple fixing members 12. One side of the multiple fixing members 12 is connected to the fixing base 11, and the other side of the multiple fixing members 12 is used to connect to or stop the shock absorber tower 3.

[0026] For example, such as Figure 1 As shown, the fixing base 11 can be a corner plate-shaped structure. In other embodiments, the fixing base 11 can also be a block-shaped structure, a plate-shaped structure, etc. In use, the fixing base 11 can be directly fixed to the ground, and the fixing base 11 mainly provides an assembly base for the aforementioned fixing component 12.

[0027] The fastener 12 can be a beam-shaped structure or a block-shaped structure. The left end or left side of each fastener 12 can be connected and fixed to the right side of the fixing seat 11. In use, the right end or right side of each fastener 12 can be directly connected and fixed to the vehicle's shock absorber tower 3 or fit against it to stop it, thereby limiting and fixing the shock absorber tower 3.

[0028] The loading component 2 includes an extruder 21, a sensor 22, and a driver 23. The driver 23 is used to drive the extruder 21 to push the shock absorber tower 3. The sensor 22 is located between the extruder 21 and the driver 23 and is used to monitor the pressure load applied by the extruder 21 to the shock absorber tower 3.

[0029] For example, such as Figure 1 As shown, the extrusion member 21 can be a columnar structure, and the actuator 23 can be a linear drive, for example, the actuator 23 can be a hydraulic cylinder, etc. The loading assembly 2 can be located on the right side of the shock absorber tower 3, wherein both the extrusion member 21 and the actuator 23 can be arranged to extend generally from left front to right rear. The sensor 22 can be a pressure sensor 22, and the sensor 22 can be fixed between the extrusion member 21 and the drive end of the actuator 23.

[0030] After the shock absorber tower 3 is installed and fixed by the aforementioned fixing component 1, the loading component 2 can be used to apply a load to the shock absorber tower 3, thereby simulating a collision test on the shock absorber tower 3. The sensor 22 can monitor the pressure load applied by the loading component 2, thereby enabling the acquisition of pressure data.

[0031] The shock absorber tower test device of this utility model can perform collision test verification on the shock absorber tower 3. Thus, before the whole vehicle collision, the device can accurately obtain the structural path strength and weak points of the shock absorber tower 3, which facilitates the rectification and optimization before the whole vehicle collision and can also provide effective data support for the whole vehicle design verification.

[0032] In some embodiments, the fixing base 11 includes a base plate 112 and an upright plate 111 arranged intersecting each other. The upright plate 111 is disposed on one side of the base plate 112, and one side of each of the plurality of fixing members 12 is connected to the upright plate 111.

[0033] For example, such as Figure 1 As shown, both the base plate 112 and the upright plate 111 can be rectangular flat plates. The base plate 112 can be arranged horizontally, and the upright plate 111 can be arranged vertically. During installation, the base plate 112 can be directly fixed to the ground, while the upright plate 111 can be connected to the right side of the base plate 112. The left end or left side of the aforementioned multiple fasteners 12 can be connected and fixed to the right side of the upright plate 111. This simplifies the overall structure of the fixing base 11 and also meets the assembly and usage requirements of the fasteners 12.

[0034] In some embodiments, the plurality of fasteners 12 include a crossbeam 121 that extends toward the side of the upright plate 111 away from the bottom plate 112, and one end of the crossbeam 121 is connected to the upright plate 111, and the other end of the crossbeam 121 is used to connect to the shock absorber tower 3.

[0035] For example, such as Figure 1 As shown, the crossbeam 121 can be a square beam structure, and there can be two crossbeams 121. Both crossbeams 121 can extend in the left-right direction, and the two crossbeams 121 can be arranged at intervals in the front-back direction. The left end of each crossbeam 121 can be connected and fixed to the vertical plate 111, and the specific fixing method can be fasteners such as screws, welding, etc. The right end of each crossbeam 121 can be connected and fixed to the vibration damping tower 3, thereby meeting the usage requirements of fixing the vibration damping tower 3.

[0036] In some embodiments, the crossbeam 121 is connected to the damping tower 3 by a first fastener 13, and the end of the crossbeam 121 is provided with a first hole 1211 through which the first fastener 13 passes. For example, as Figure 1 As shown, the first fastener 13 can be a bolt, etc., and each crossbeam 121 can have a first hole 1211 at the right end, and the first hole 1211 can penetrate the crossbeam 121 along the vertical direction.

[0037] During assembly, the shock absorber tower 3 can be placed on the bottom side of each crossbeam 121, and then the corresponding first fastener 13 can be installed in the first hole 1211 of each crossbeam 121. Finally, the shock absorber tower 3 and the crossbeam 121 can be connected and fixed by two first fasteners 13, which facilitates installation and disassembly, ensures the structural strength of the connection, and fully meets the needs of the collision test.

[0038] In some embodiments, the plurality of fasteners 12 include a limiting block 122, which is disposed on the side of the upright plate 111 away from the bottom plate 112, and one side of the limiting block 122 is connected to the upright plate 111, while the other side of the limiting block 122 is used to stop against the shock absorber tower 3.

[0039] For example, such as Figure 1 As shown, there can be two limiting blocks 122. Both limiting blocks 122 can be block-shaped structures. The two limiting blocks 122 can be respectively located below the two crossbeams 121, and the two limiting blocks 122 can be arranged at intervals in the front-back direction.

[0040] The left side of each limiting block 122 can be directly connected to the upright plate 111, and the right side of each limiting block 122 can be provided with a mating surface that matches the shape of the shock absorber tower 3. During assembly, the mating surface on the right side of each limiting block 122 can directly fit and cooperate with the corresponding surface of the shock absorber tower 3, thereby enhancing the limiting constraint effect on the shock absorber tower 3.

[0041] In some embodiments, the limiting block 122 is mounted on the upright plate 111 by a second fastener 14, and the upright plate 111 has a second hole through which the second fastener 14 passes. For example, Figure 1 As shown, the second fastener 14 can be a bolt, etc., and the upright plate 111 can be provided with multiple second holes, each of which can penetrate the upright plate 111 in the left-right direction. During assembly, the limiting block 122 can be placed on the right side of the upright plate 111 first, and then the second fastener 14 can be passed through the corresponding second hole and connected and fixed with the limiting block 122, thus achieving convenient installation.

[0042] In some embodiments, the fixing base 11 includes a diagonal brace 113, which is disposed within the angle formed by the base plate 112 and the upright plate 111, and is connected to both the upright plate 111 and the base plate 112. For example, as... Figure 1As shown, the diagonal brace 113 can be a triangular plate. The base plate 112 and the upright plate 111 can be arranged perpendicularly. The diagonal brace 113 can be located within the right angle formed by the base plate 112 and the upright plate 111. One edge of the diagonal brace 113 can be directly connected to the base plate 112 by welding or other means, and the other edge of the diagonal brace 113 can be directly connected to the upright plate 111 by welding or other means. The diagonal brace 113 can enhance the impact resistance of the upright plate 111, thus fully meeting the requirements of the collision test.

[0043] In some embodiments, the diagonal bracing plate 113 is arranged perpendicularly to both the upright plate 111 and the base plate 112. For example, as... Figure 1 As shown, the inclined brace 113 can be a straight plate. One right-angled side of the inclined brace 113 can be welded and fixed to the base plate 112, and the other right-angled side of the inclined brace 113 can be welded and fixed to the upright plate 111. This further enhances the overall structural strength of the fixing seat 11 and fully meets the needs of the collision test.

[0044] In some embodiments, the base plate 112 is connected to a set plane by a plurality of third fasteners. The base plate 112 is provided with a plurality of third holes 1121, and the plurality of third fasteners are fitted into the plurality of third holes 1121 in a corresponding manner.

[0045] For example, such as Figure 1 As shown, the third fastener can be an anchor bolt, and the base plate 112 can be provided with four third holes 1121, two of which can be provided on the front side of the bracing plate 113, and the other two third holes 1121 can be provided on the rear side of the bracing plate 113.

[0046] The set plane can be the ground, or in some other embodiments, it can be a base platform, etc. During installation, an anchor bolt can be installed in each third hole 1121, and the base plate 112 can be fixed by means of the anchor bolt.

[0047] In some embodiments, the extrusion member 21 includes an end plate 211 for contacting and abutting against the shock absorber tower 3. For example, as... Figure 1 As shown, the end plate 211 can be a rectangular plate. The end plate 211 can be set at the end of the extrusion member 21 used to stop the shock absorber tower 3. The setting of the end plate 211 can increase the effective area of ​​the extrusion member 21 and the shock absorber tower 3, thereby ensuring the effectiveness of the collision test.

[0048] In some embodiments, the shock absorber tower test device of this utility model can verify the strength of the cast aluminum shock absorber tower 3 by conducting static compression tests, so as to achieve the test purpose of verifying its own crushing strength. The specific experimental process can be as follows:

[0049] 1. The direction of force on the subframe during a vehicle collision can be simulated first through a simulation system.

[0050] 2. Set up the fixed component 1 according to the test requirements, and then fix the sample (shock absorber tower 3) at the fixed component 1 according to the coordinates, and ensure that the posture of the sample is consistent with the actual vehicle.

[0051] 3. Install the constraint fixtures in all directions into place, and finally arrange the actuator (driver 23) and adjust the attitude of the actuator, and lock all devices.

[0052] 4. The sample is loaded using a single-sided loading method. The actuating cylinder controls the loading at a constant speed. When the sensor 22 detects a significant decrease in the load on the actuating cylinder, indicating that the sample has experienced obvious fracture and damage, the loading can be stopped immediately.

[0053] 5. Record the displacement and corresponding load values ​​during the test, and finally output the force-displacement curve.
