[0001] The utility model relates to the technical field of compressive testing of the trunk cover, and particularly relates to a compressive testing device for an automobile trunk cover. Background Technique

[0002] As an important part of the automobile interior, the automobile trunk cover is generally installed in the trunk to play a role in isolation and beautification. The automobile trunk cover is installed in the trunk of the automobile, and items can be placed above it. During the R & D and manufacturing process, in order to test the compressive performance of the automobile trunk cover, multiple compressive testing devices need to be designed and manufactured according to the shape dimensions and support points of the trunk covers of different vehicle factories each time.

[0003] When conducting a compressive experiment on the automobile trunk cover, generally, a hydraulic push rod is used to drive a pressing block to press the trunk cover, and the deformation effect is observed and recorded. However, since the automobile trunk cover needs to withstand extrusion of different areas during use, the above-mentioned compressive experiment has limitations and it is difficult to conduct a compressive experiment on extrusion of different areas. Therefore, the automobile trunk cover needs to be experimented in different devices, so it is not convenient and automated enough to use.

[0004] For this reason, a compressive testing device for an automobile trunk cover is proposed. Content of the Utility Model

[0025] Such as Figures 1-5As shown in the figure, an anti-compression test device for the trunk cover of an automobile includes a bottom plate 1. At the top of the bottom plate 1, there is an installation frame 2. On one side of the installation frame 2, there are a controller 3 and a display 4. Inside the installation frame 2, there is a placement frame 5. At the top of the placement frame 5, there are two sliding grooves 501. On the placement frame 5, there is a trunk cover 10. On the placement frame 5, there is a driving member 6 for driving the trunk cover 10 to move forward. The driving member 6 includes a slider 606 slidably arranged inside the sliding groove 501. Inside the installation frame 2, there are multiple pressurizing members 8 for pressurizing the trunk cover 10. The pressurizing member 8 includes a hydraulic push rod 801 arranged at the top end inside the installation frame 2. The telescopic end of the hydraulic push rod 801 is connected to a fixing plate 802. At the bottom end of the fixing plate 802, there is a pressure sensor 803. At the bottom end of the pressure sensor 803, there is a pressurizing block 804. On both sides corresponding to each other inside the installation frame 2, there are multiple evenly arranged high-definition cameras 7. Specifically, place the trunk cover 10 on the slider 606. The arranged pressurizing member 8 can perform a pressurizing test on the trunk cover 10. During the test, the arranged limiting member 9 can squeeze and limit the trunk cover 10 to prevent the trunk cover 10 from moving during the pressurizing test. When performing the anti-compression test, the arranged hydraulic push rod 801 can push the pressurizing block 804 downward to perform an extrusion test on the trunk cover 10. When the pressure sensor 803 reaches the set value, the hydraulic push rod 801 will be controlled to stop pressurizing. The arranged high-definition cameras 7 can photograph the anti-compression result, and the photographing result can be transmitted to the display 4, which is convenient for the staff to observe and record the anti-compression result. After the pressurizing test of the pressurizing block 804 in this area is successful, the arranged driving member 6 can push the trunk cover 10 to the lower part of the next pressurizing member 8 for pressurizing test. Therefore, it can be tested which area of the pressurizing block 804 will cause damage to the trunk cover 10 under the same pressure. The process is more automated during the test, and there is no need to move the trunk cover 10 from different test machines, making it more convenient to use.

[0026] As Figure 5 shown, on one side of the placement frame 5, there is a motor 601. One end of the motor 601 is connected to a first pulley 602. Inside the sliding groove 501, a lead screw 605 is rotatably arranged. The lead screw 605 on the same side as the motor 601 is connected to the other end of the motor 601. Specifically, when the motor 601 works, it can drive the lead screw 605 to rotate, thereby driving the slider 606 to slide inside the sliding groove 501, and thus can also drive the trunk cover 10 to translate.

[0027] As Figure 5As shown in the figure, one end of the lead screw 605 away from the motor 601 is connected to a second pulley 603, and a belt 604 is driven and conveyed between the second pulley 603 and the first pulley 602. Specifically, under the driving and conveying action of the belt 604, the lead screw 605 inside another sliding groove 501 can be driven to rotate synchronously, so that the two sliders 606 can move synchronously.

[0028] As Figure 3 shown in the figure, the slider 606 is threadedly sleeved on the lead screw 605.

[0029] As Figure 2 shown in the figure, the cross-sectional area of the pressing block 804 in the pressing member 8 gradually decreases, and the high-definition camera 7 corresponds to the position of the pressing block 804. Specifically, as the cross-sectional area of the pressing block 804 gradually decreases, when pressing, the pressure on the trunk lid 10 will be more concentrated, so that the compressive capacity of the trunk lid 10 in different scenarios can be tested.

[0030] As Figure 4 shown in the figure, a limiting member 9 for squeezing and limiting the trunk lid 10 is provided on the fixing plate 802. The limiting member 9 includes a telescopic rod 901 provided at the bottom end of the fixing plate 802. A spring 902 is sleeved on the telescopic rod 901. The telescopic end of the telescopic rod 901 is connected to a limiting pressing plate 903, and the limiting pressing plate 903 corresponds to the position of the placement frame 5. Specifically, when performing a pressing test on the trunk lid 10, the limiting pressing plate 903 can play a role in squeezing and limiting the trunk lid 10, so that the position of the trunk lid 10 can be prevented from shifting during subsequent pressing.

[0031] In summary: Place the trunk lid 10 on the slider 606. The provided pressing member 8 can perform a pressing test on the trunk lid 10. During the test, the provided limiting member 9 can squeeze and limit the trunk lid 10 to prevent the trunk lid 10 from moving during the pressing test. When performing a compressive test, the provided hydraulic push rod 801 can push the pressing block 804 downward to perform a squeezing test on the trunk lid 10. When the pressure sensor 803 reaches the set value, the hydraulic push rod 801 will be controlled to stop pressing. The provided high-definition camera 7 can capture the compressive test result, and the captured result can be transmitted to the display 4, which is convenient for the staff to observe and record the compressive test result. After the pressing test of the pressing block 804 with this area is successful, the provided driving member 6 can push the trunk lid 10 to the lower part of the next pressing member 8 for a pressing test, so that it can be tested which area of the pressing block 804 will cause damage to the trunk lid 10 under the same pressure. The process is more automated during the test, and there is no need to move the trunk lid 10 from different test machines, which is more convenient to use.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only the principle of the present utility model.
