Description

Technical Field

[0001] This utility model relates to the field of testing devices, and in particular to a battery handle strength testing device. Background Technology

[0002] In the design and manufacturing of modern medical devices, electric bicycle battery packs, and household appliances, the mechanical strength of the handle directly affects the product's safety and lifespan. The handle directly bears the weight of the entire product; if its strength is insufficient during handling and movement, it is highly susceptible to breakage or permanent deformation, leading to product damage from falls.

[0003] Currently, many manufacturers still use simple methods such as suspending heavy objects or manual tensioning and compression to conduct rough load tests. These methods lack precise force measuring devices, making it difficult to accurately read and record the changes in the handle under stress, and to determine whether it meets the design strength requirements. Utility Model Content

The base is used to place the battery, and a fixing mechanism is provided on the base to fix the battery placed on it. An opening is provided in the middle of the top plate, and a suspension rope passing through the opening is connected to the hook of the tension gauge. The end of the suspension rope is connected to a hook, and the hook is hooked on the battery handle.

Detailed Implementation

[0016] The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0017] like Figures 1 to 2 As shown in the figure, a battery handle strength testing device provided in this embodiment of the present invention includes a base 1 and a top plate 12 fixed above the base 1 by a support column 11. The lower surface of the base 1 is provided with shock-absorbing pads. A lifting mechanism is installed on the top plate 12, and a tension gauge 15 is mounted on the lifting mechanism. The base 1 is used to place a battery 3, and a fixing mechanism is provided on the base 1 to fix the battery 3 placed on it. An opening 121 is provided in the middle of the top plate 12. A suspension rope 16, which is a steel wire rope or a high-strength nylon rope, is connected to the hook of the tension gauge 15 and passes through the opening 121. The end of the suspension rope 16 is connected to a hook 17, which is hooked onto the handle of the battery 3. The handle 31 is mounted on a barrier 2 located around the upper surface of the base 1. Each of the three side walls of the barrier 2 has a rectangular opening 20, and the inner wall of each rectangular opening 20 has a slot 21. A baffle 22 is inserted into each rectangular opening 20, and its periphery is inserted into the slot 21. The baffle 22 is made of transparent acrylic. The force gauge 15 is a digital display force gauge and is connected to a data display screen. The data display screen is also connected to a pressure sensor mounted on the base 1. The pressure sensor detects the weight of the battery 3. The transparent baffle 22 facilitates the removal and placement of the battery while allowing observation of its internal condition, and also prevents liquid from splashing inside the battery 3 if the handle 31 breaks.

[0018] Insert the battery 3 into the base 1 through the rectangular opening 20 and close the baffle 22. Use the fixing mechanism to press and fix the battery 3 onto the base 1. The operator hooks the hook 17 onto the handle 31 of the battery 3. By controlling the lifting mechanism, the tension gauge 15 moves upward. At this time, a vertical upward pulling force is applied to the handle 31 through the tension gauge 15 and the suspension rope 16. The operator can read the pulling force value in real time directly from the screen of the tension gauge 15 or the remote display screen connected to it until the force value specified by the test standard is reached or the handle is damaged.

[0019] Specifically, to facilitate securing the battery 3 placed on the upper surface of the base 1 and prevent the battery 3 from moving upwards when lifted; such as Figure 3 The fixing mechanism includes two fixing units located at both ends of the battery 3. Each fixing unit includes two columns 10 respectively set on the upper surface of the base 1 and a crossbar 4. Both ends of the crossbar 4 are provided with through holes for the ends of the columns 10 to pass through. The ends of the columns 10 are provided with threaded sections, and nuts 101 with their end faces abutting against the upper surface of the crossbar 4 are threaded onto the threaded sections. During installation, the battery 3 is first placed on the upper surface of the base 1, the crossbar 4 is pressed on the top of the battery 3, and then the nuts 101 are tightened. The crossbar 4 can be used to firmly press the battery 3 onto the base 1 to prevent the battery 3 from being lifted during testing.

[0020] The present invention provides two specific implementation methods for the lifting mechanism.

[0021] Method 1: For example Figure 1-3 A side mounting plate 13 is fixed on the upper surface of the top plate 12 located on one side of the opening 121. The lifting mechanism includes a telescopic module 14 installed on one side of the side mounting plate 13. The telescopic module 14 is an electric push rod. The cylinder of the electric push rod is fixed on the side mounting plate 13. The pull ring at the top of the tension gauge 15 is connected to the output end of the telescopic module 14. The output end of the telescopic module 14 passes through the opening 121.

[0022] Method 2: For example Figure 4 The lifting mechanism includes a lower base plate 191 and an upper base plate 19. A pair of guide rods 190 are connected between the lower base plate 191 and the upper base plate 19. A lead screw 18 is provided between the two guide rods 190. The two ends of the lead screw 18 are rotatably mounted on the lower base plate 191 and the upper base plate 19 respectively through bearings. A hand crank 181 is connected to the top of the guide rod 190. The mechanism also includes a movable block 182. A nut that mates with the lead screw 18 and a through hole that mates with the guide rod 190 are installed on the movable block 182. A vertical mounting plate 183 is provided at the end of the movable block 182. A tension gauge 15 is installed on one side of the vertical mounting plate 183. During testing, the operator can precisely control the lifting and lowering of the movable block 182 by cranking the hand crank 181 clockwise or counterclockwise, thereby applying a pulling force to the battery handle.

[0023] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
