Description

Technical Field

[0001] This application relates to the field of battery technology, specifically to a drop test device for electric motorcycle batteries. Background Technology

[0002] Electric motorcycles are increasingly becoming an important personal transportation tool due to their convenience and environmental friendliness. Their core power source is the battery pack, and the safety performance of the battery pack directly relates to the safety of users' lives and property. Among the many safety tests for battery packs, the drop test is a crucial test that simulates the conditions of the battery pack falling from a height during transportation, installation, use, or accidents. It is used to verify the structural integrity of the battery pack, the stability of the internal cells, and the sealing performance, preventing serious safety accidents such as short circuits, leaks, fires, or even explosions caused by drop impacts.

[0003] Currently, publicly available battery drop test devices typically include a protective housing, a guide mechanism housed within the housing, a sliding seat that can slide along the guide mechanism, and a clamping and releasing mechanism for holding and releasing the battery. During testing, the operator must first secure the battery to the sliding seat using the clamping mechanism, then lift the battery to a predetermined height using a lifting mechanism, and finally release it to allow it to fall freely onto the impact platform.

[0004] For example, patent CN217586231U discloses a battery cell drop safety test device. This patent sets up a battery cell support platform that can be quickly flipped to a vertical position, allowing the battery cell to fall in a weightless state to test its safety performance after the drop.

[0005] However, when testing large and heavy electric motorcycle batteries, firstly, operators need to move the batteries, which weigh tens of kilograms, into the device and lift them to a certain height for clamping and fixing. This process is not only labor-intensive and inefficient, but also poses a significant safety risk of the battery falling out of their hands and injuring personnel. Secondly, if the battery ruptures after the test, it may leak corrosive electrolyte or produce sharp metal fragments. Manually entering the sealed enclosure to clean it also faces high risks, and the cleaning process is cumbersome, seriously affecting the testing efficiency.

[0006] Therefore, it is necessary to provide a drop test device for electric motorcycle batteries to solve the above problems.

[0007] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0033] like Figures 1-3As shown, this application provides a drop test device for electric motorcycle batteries, which is mainly used in the production line, quality inspection laboratory or R&D center of electric motorcycle power batteries. It is used to simulate the working conditions of the battery falling from a height during transportation, use or accident, so as to test its structural strength, sealing performance and safety reliability. Specifically, the drop test device for electric motorcycle batteries includes a cover 1. In order to guide the battery under test to perform a precise vertical drop movement inside the cover 1, a detection mechanism 2 is set inside the cover 1. The detection mechanism 2 includes two sets of vertical guide posts 20 fixedly set on both sides inside the cover 1. A sliding seat 21 is slidably set on the guide post 20. In order to firmly clamp the battery under test, a clamp 27 is installed at the bottom end of the sliding seat 21. The operator can clamp and fix the battery directly below it by operating the clamp 27, thus preparing for the test.

[0034] In order to drive and control the lifting and locking of the sliding seat 21, a cylinder 22 is fixedly installed at the upper end of the cover 1. The output end of the cylinder 22 extends through the cover 1 into the interior, and a fixing plate 23 is fixedly connected to its end. In order to provide a stable and reliable clamping force, a dual-axis cylinder 24 is fixedly installed on the fixing plate 23. The two output ends of the dual-axis cylinder 24 are horizontally displaced relative to each other, and a clamping plate 25 is fixedly connected to each output end.

[0035] Correspondingly, a positioning ring 26 is fixedly provided at the upper end of the sliding seat 21. By driving the dual-axis cylinder 24, the clamping plates 25 at both ends can move towards each other to clamp the positioning ring 26, or move in the opposite direction to release the positioning ring 26, thereby realizing the mechanical locking and unlocking of the sliding seat 21.

[0036] When the test begins, the battery to be tested is first initially fixed on the sliding seat 21 by the clamp 27 at the bottom. Then, the dual-axis cylinder 24 is activated, so that the clamping plate 25 at its output end clamps the positioning ring 26 at the upper end of the sliding seat 21. Then, the cylinder 22 is activated, and its output end drives the locked sliding seat 21 to slide smoothly upward along the guide post 20 through the fixing plate 23 and the dual-axis cylinder 24 until it is raised to the preset drop height.

[0037] When testing is required, the dual-axis cylinder 24 is activated again, causing the clamping plate 25 to release the positioning ring 26. The sliding seat 21 and the battery clamped on it will then slide freely and accelerate down the guide post 20 under the action of gravity, eventually hitting the bottom of the inner end of the cover 1 to complete a drop test.

[0038] To prevent electric motorcycle batteries from being bulky and heavy, and potentially ruptured after testing, and to facilitate safe and effortless handling of batteries by staff, such as... Figures 2-5 As shown, a pick-and-place mechanism 3 is provided at the bottom of the inner part of the housing 1;

[0039] The picking and delivering mechanism 3 includes a mounting plate 30 that is slidably sleeved on the guide post 20, so that the mounting plate 30 can move along the guide post 20 in the vertical direction. In order to support the mounting plate 30 and withstand the impact of falling, a plurality of support legs 31 are fixedly provided at its bottom end.

[0040] In order to catch the battery debris after it falls and send it out smoothly, guide rails 34 are fixedly installed on both sides of the upper end face of the mounting plate 30. The guide rails 34 have slots, and pulleys 35 are slidably installed on the slots. At the same time, a tray 37 for directly supporting the battery is installed between the pulleys 35 through the pulley seats. The tray 37 can slide horizontally along the guide rails 34, and the tray 37 has a rim around its perimeter to facilitate the placement of battery fragments.

[0041] In order to drive the tray 37 to move horizontally, a first electric cylinder 32 is installed at the bottom of the mounting plate 30. At the same time, a guide groove 39 is opened in the middle of the mounting plate 30. The output end of the first electric cylinder 32 passes through the guide groove 39 and is fixedly connected to the bottom of the tray 37. Thus, starting the first electric cylinder 32 can push or pull the tray 37, so that it slides out or into the cover 1 along the guide rail 34, which greatly facilitates the workers to pick up, put down and clean the batteries outside the cover 1.

[0042] In order to transport the battery placed in the tray 37 to the underside of the clamp 27 for clamping before testing, a positioning groove 38 matching the shape of the battery to be tested is provided on the upper surface of the tray 37 to limit the placement position of the battery.

[0043] Finally, in order to drive the entire picking and delivering mechanism 3 to move up and down, multiple sets of second electric cylinders 36 are installed at the bottom of the inside of the cover 1. The output ends of the second electric cylinders 36 are all fixedly connected to the bottom of the mounting plate 30.

[0044] Before the test begins, the staff first places the battery to be tested into the positioning slot 38 of the tray 37 located outside the cover 1, and then starts the second electric cylinder 36 to push the entire tray 37 and the battery up until the battery is lifted to the same height as the clamp 27 and in close contact.

[0045] At this time, the operating clamp 27 can firmly clamp the battery onto the sliding seat 21. After clamping is completed, the second electric cylinder 36 drives the pick-and-place mechanism 3 to descend to the bottom of the cover 1, leaving enough space for subsequent drop tests.

[0046] It should be further explained that by controlling the lifting stroke of the second electric cylinder 36, the initial height of the tray 37 can be flexibly adjusted. This allows the device to adapt to batteries of different sizes and simulate drop test scenarios of different heights, thereby enhancing the versatility and testing flexibility of the equipment.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
