Description

Technical Field

[0001] This utility model relates to the field of mobile energy storage power supply testing technology, and in particular to a test device for simulating bumpy road surfaces. Background Technology

[0002] Mobile energy storage devices are typically equipped with casters at the bottom for easy movement. Currently, the selection of casters for mobile energy storage devices is usually based solely on the device's own weight, neglecting factors such as road bumps that may occur in real-world applications. This simplified selection method fails to fully reflect the load the casters will bear during actual use, leading to a bias in the assessment of the device's overall mobile durability.

[0005] Furthermore, the aforementioned simulated bumpy road test device also includes screws for connecting the base plate, gasket, and bump together.

[0006] Furthermore, the aforementioned simulated bumpy road test device also includes a first nut, wherein the screw shank passes through the base plate, washer, and protrusion and is threadedly connected to the first nut.

[0007] Furthermore, the screw has a shank length of 10mm to 30mm.

[0008] Furthermore, the connecting piece is provided with a plurality of mounting holes, and the substrate is provided with a connecting portion passing through the mounting holes.

[0009] Furthermore, the aforementioned simulated bumpy road test device also includes a second nut, and the connecting part is threadedly connected to the second nut, which is used to fix the connecting piece on the base plate.

[0013] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0014] Please refer to Figure 1 and Figure 2As shown, mobile energy storage devices are typically equipped with wheels at the bottom for easy movement. Currently, the selection of wheels for mobile energy storage devices is usually based solely on the device's own weight, neglecting factors such as road bumps that may occur in actual application scenarios. This simplified selection method cannot fully reflect the load borne by the wheels during actual use, leading to a bias in the assessment of the overall mobile durability of the device. In this embodiment, a bump 3 is added to the base plate 1 to simulate uneven road conditions for road surface testing of the mobile energy storage device. Furthermore, by placing shims 2 of different thicknesses between the base plate 1 and the bump 3, the height of the bump 3 can be adjusted, thereby simulating various bumpy road surfaces for durability testing.

[0015] Please refer to Figure 1 , Figure 2 and Figure 4 As shown, the present invention provides a simulated bumpy road surface testing device, comprising at least one road surface testing module. Each road surface testing module includes: a base plate 1, a pad 2, and a protrusion 3. The pad 2 is disposed on the surface of the base plate 1, and the protrusion 3 is disposed on the top of the pad 2. The base plate 1 is provided with a connecting piece 6 at its end along its length direction and / or width direction. The connecting piece 6 is used to connect other base plates 1 to form an extended continuous bumpy road surface.

[0016] Working principle: Bumps 3 are added to the base plate 1 to simulate uneven road conditions. The mobile energy storage device can then be driven to repeatedly move on the base plate to conduct durability tests on the rollers. By placing shims 2 of different thicknesses between the base plate 1 and the bumps 3, the height of the bumps 3 can be adjusted, thus simulating various bumpy road surfaces for durability testing. Furthermore, by splicing multiple base plates 1 together using connecting pieces 6, a larger area and more complex continuous bumpy test road surface can be constructed.

[0017] The protrusion 3 is made of steel plate, with a thickness of 3mm to 8mm and a width of 20mm to 30mm. By limiting the protrusion 3 to a steel plate, and specifying its thickness and width, the strength of the protrusion 3 can be ensured. Preferably, the protrusion 3 has a thickness of 5mm and a width of 30mm.

[0018] In some implementations, please refer to Figure 2 and Figure 3 As shown, the aforementioned simulated bumpy road test device also includes a screw 4, which is used to connect the base plate 1, the washer 2, and the protrusion 3 together. Specifically, the screw 4 passes through the base plate 1, the washer 2, and the protrusion 3 and is threadedly connected to the first nut 5. By having the screw 4 pass through the base plate 1, the washer 2, and the protrusion 3 and be threadedly connected to the first nut 5, the protrusion 3 is fixedly mounted on the base plate 1.

[0019] Screw 4 can be a bolt or a press-fit screw.

[0020] In some embodiments, the screw 4 has a thread length of 10 mm to 30 mm. The thread length of the screw 4 is limited to accommodate various mounting heights of the protrusion 3. Preferably, the screw 4 has a thread length of 20 mm. In some implementations, please refer to Figure 5 As shown, the connecting piece 6 has multiple mounting holes 61, and the substrate 1 has a connecting portion 11 that passes through the mounting holes 61. Two substrates 1 pass through the mounting holes 61 of the connecting piece 6 via the connecting portion 11, so that the two substrates 1 are spliced ​​together.

[0021] Further, please refer to Figure 5 As shown, the aforementioned simulated bumpy road test device further includes a second nut 7, and the connecting part 11 is threadedly connected to the second nut 7. The second nut 7 is used to fix the connecting piece 6 onto the base plate 1. By threading the second nut 7 onto the connecting part 11, the connecting piece 6 is fixedly mounted on the base plate 1.

[0022] The connecting part 11 can be a bolt or a press-fit screw.
