DETAILED DESCRIPTION
[0028] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0029] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", refer to the inside and outside of the contour of each component itself. The terms "first" and "second" are used to distinguish one element from another element and do not have order or importance. In addition, when the following description refers to the drawings, the same reference numerals in different drawings represent the same or similar elements, and this disclosure will not repeat them.
[0030] According to some embodiments of the present disclosure, a test device for a shock tower is provided, referring to Figures 1 to 5 As shown in the figure, the test device is used to be connected to the body-in-white 10, the body-in-white 10 includes two shock-absorbing towers 101 spaced apart in the transverse direction (with reference to the width direction of the body-in-white 10), the test device includes a first constraint structure 1 and a load application structure 2, the first constraint structure 1 is used to be supported and fixed to one of the shock-absorbing towers 101, and the load application structure 2 is used to be supported and fixed to the other shock-absorbing tower 101.
[0031] Through the above technical solution, in the test device of the shock tower provided by the present disclosure, the load applying structure 2 can apply a load to the shock tower 101 fixedly connected to itself, so as to test the strength and / or durability of the shock tower 101. Here, since the test device of the present disclosure is a test of the shock tower 101 on the body-in-white 10, the posture of the shock tower 101 in the test state is basically the same as the posture of the shock tower 101 in the actual use state. Therefore, the force condition of the shock tower 101 in the test state is also basically the same as the force condition of the shock tower 101 in the actual use state. Therefore, the test device has a more accurate test result on the strength and durability of the shock tower 101. In addition, since the two shock towers 101 of the body-in-white 10 are connected together, the first constraint structure 1 can be used to support and fix another shock tower 101, thereby constraining the other shock tower 101 and preventing the other shock tower 101 from vibrating and deforming and affecting the test result of the test device. In addition, since the load on the shock tower 101 will be transferred to other components of the body-in-white 10 during the test, the test device disclosed in the present invention can also test the strength and durability of each component on the load transfer path. Therefore, such a setting also effectively shortens the test cycle of the body-in-white 10.
[0032] It should be noted that the load application structure 2 generally includes an actuator 21, which can simulate the shock absorber to apply a load to the shock tower 101. During the test, the actuator 21 of the load application structure 2 can apply a load of substantially the same value to one of the shock towers 101 to test the strength of the shock tower 101; and the actuator 21 of the load application structure 2 can apply a load of different value to another shock tower 101 to test the durability of the shock tower 101. In this way, it is possible to avoid using the same shock tower 101 for separate strength tests and durability tests, thereby ensuring the accuracy of the strength test results and the accuracy of the durability test results.
[0033] It should also be noted that the various components on the above-mentioned load transfer path are mainly concentrated on the front cabin. For example, the various components on the above-mentioned load transfer path may include the front longitudinal beam of the front cabin, the front subframe 103, etc., and the present disclosure does not impose too many restrictions on this.
[0034] In some embodiments of the present disclosure, reference Figures 1 to 5As shown in , the load application structure 2 may include a coaxially arranged actuator 21 and a first connecting plate 22, and the first connecting plate 22 is used to be fixedly connected to the corresponding shock tower 101. Here, in the actual arrangement, the central axis of the actuator 21 can be arranged to coincide with the central axis of the matching hole 1011 of the corresponding shock tower 101. Even if the actuator 21 is coaxially arranged with the corresponding matching hole 1011, since the matching hole 1011 is used to connect with the shock absorber, such an arrangement can ensure that the direction of load application is parallel to the central axis of the matching hole 1011, thereby enabling the actuator 21 to accurately simulate the shock absorber to apply load to the shock tower 101, thereby ensuring the accuracy of the test results. Among them, the working principle of the actuator 21 is well known to those skilled in the art, and the present disclosure will not be repeated here. In addition, by arranging the first connecting plate 22 to be coaxially arranged with the actuator 21, it is convenient to connect the first connecting plate 22 with the matching hole 1011 of the corresponding shock tower 101.
[0035] It should be noted that, since the two shock towers 101 of the body-in-white 10 are arranged axially symmetrically, the first connecting plate 22 can be connected to any shock tower 101, so that the load application structure 2 can use different shock towers 101 to test the strength and durability of the shock towers 101. In addition, the body-in-white of the present disclosure can refer to the entire body-in-white, or to the front half of the body-in-white, which includes the front cabin and the above-mentioned two shock towers.
[0036] In some embodiments of the present disclosure, reference Figure 1 as well as Figures 4 to 6 As shown in , a first rod 23 may be connected between the actuator 21 and the first connecting disk 22. Here, adjusting the length of the first rod 23 may allow the actuator 21 to adapt to shock towers 101 of different heights. The first rod 23 and the actuator 21 may be coaxially arranged to ensure that the direction of load application is parallel to the central axis of the matching hole 1011. The first rod 23 may be rotatably connected to the first connecting disk 22 via a first ball head 24. In this way, the first ball head 24 may allow the first connecting disk 22 to rotate universally relative to the first rod 23, thereby avoiding jamming between the first rod 23 and the first connecting disk 22 during load loading, and ensuring that the first connecting disk 22 and the matching hole 1011 remain coaxially arranged, thereby further ensuring that the direction of load application is parallel to the central axis of the matching hole 1011. Here, in some embodiments, reference Figure 6 As shown in FIG. 2 , the first ball head 24 can be connected to the first connecting disk 22 through the connecting frame 27 , thereby ensuring the reliability of the rotational connection between the first connecting disk 22 and the first ball head 24 .
[0037] In some embodiments of the present disclosure, reference Figure 1 as well as Figures 4 to 6As shown in , the first rod 23 can be rotatably connected to the actuator 21 through the second ball head 25. Here, the second ball head 25 can realize the universal rotation of the first rod 23 compared to the actuator 21, thereby avoiding the first rod 23 and the actuator 21 from getting stuck during the load loading process, thereby preventing the actuator 21 from being damaged. Here, in some embodiments, reference Figure 6 As shown in FIG. 1 , the second ball head 25 can be connected to the actuator 21 through the connecting frame 27 , thereby ensuring the reliability of the rotation connection between the first rod 23 and the actuator 21 .

Specifically, in the actual arrangement, the support surface is configured to be perpendicular to the central axis of the corresponding matching hole 1011. It should be noted that the sum of the angle between the bottom plane 261 and the support slope 262 and the angle between the bottom plane 261 and the central axis of the actuator 21 is 90°.
[0039] In some embodiments of the present disclosure, reference Figures 4 to 6 As shown in, the first connecting plate 22 may include a first sub-plate 221 and a second sub-plate 222 which are coaxially arranged, and the second sub-plate 222 is connected to the actuator 21 via a first rod 23, wherein the first sub-plate 221 is used to be connected to the matching hole 1011 of the corresponding shock tower 101 to ensure the coaxial arrangement of the first connecting plate 22 and the corresponding matching hole 1011, wherein the diameter of the first sub-plate 221 may be equal to the diameter of the matching hole 1011, and the second sub-plate 222 is used to be fixedly connected to the corresponding shock tower 101 via fasteners to achieve a fixed connection between the first connecting plate 22 and the corresponding shock tower 101.
[0040] In some embodiments of the present disclosure, reference Figures 1 to 5As shown in , the first constraint structure 1 may include a second support seat 11, a second rod 12 and a second connection plate 13 connected in sequence, the second rod 12 and the second connection plate 13 are coaxially arranged, and the second connection plate 13 is used to be fixedly connected to the corresponding shock tower 101. Here, the second support seat 11 can support the corresponding shock tower 101, wherein the second support seat 11 may have a mounting plane parallel to the above-mentioned bottom plane 261, and the mounting plane is connected to the second rod 12, wherein the angle of the acute angle between the central axis of the second rod 12 and the mounting plane is equal to the angle of the acute angle between the central axis of the actuator 21 and the bottom plane 261. Therefore, by utilizing the symmetrical arrangement of the two shock towers 101 on the body 10, the first connecting plate 22 can be fixed to any one of the shock towers 101. Similarly, the second connecting plate 13 can also be fixed to any one of the shock towers 101. Thus, the actuator 21 can utilize the two shock towers 101 to perform strength tests and durability tests respectively, and the first constraint structure 1 can be supported and fixed to any one of the shock towers 101.
[0041] In some embodiments of the present disclosure, reference Figure 4 and Figure 5 As shown in, the second connecting plate 13 may include a third sub-plate 131 and a fourth sub-plate 132 which are coaxially arranged, and the fourth sub-plate 132 is connected to the second rod 12, wherein the third sub-plate 131 is used to be connected in the matching hole 1011 of the corresponding shock tower 101 to ensure the coaxial arrangement of the second connecting plate 13 and the corresponding matching hole 1011, wherein the diameter of the third sub-plate 131 may be equal to the diameter of the first sub-plate 221, and the fourth sub-plate 132 is used to be fixedly connected to the corresponding shock tower 101 by fasteners to realize the fixed connection between the second connecting plate 13 and the corresponding shock tower 101.
[0042] In some embodiments of the present disclosure, reference Figure 5 As shown in , a reinforcing plate 14 may be connected between the second support seat 11 and the second rod 12 , thereby improving the connection strength between the second support seat 11 and the second rod 12 , and improving the supporting effect of the second support seat 11 on the corresponding shock tower 101 .

Here, by using the cooperation of a fixed beam 31 and each support platform 32, a threshold beam 102 can be clamped and fixed, so as to support and fix the entire vehicle body, and the structure is simple and easy to operate. In addition, in the actual arrangement, the support platform 32 can be supported on the lower side of the corresponding threshold beam 102, and the fixed beam 31 can be pressed on the threshold beam 102 from above the threshold beam 102.
