Description

Technical Field

[0001] This utility model relates to the field of battery testing equipment technology, specifically to a battery pack handle pull force testing device. Background Technology

[0002] With the development of new energy technologies, various battery packs are widely used in electric vehicles, energy storage equipment and other fields. In order to facilitate handling and installation, battery packs are usually equipped with handle structures. The strength and reliability of the handle are directly related to the safety of battery pack use. Therefore, it is necessary to conduct strict tensile tests on the battery pack handle.

[0003] In existing technologies, devices that use controllable mechanical tension to reproduce the stress scenarios of battery pack handles in actual use and verify the structural strength and reliability of battery pack handles have the core objective of simulating the tension that the handles bear under actual handling, installation, or emergency conditions to determine whether they meet design standards.

[0004] The connecting components and tensile actuators of the testing device are mostly integrated and fixed. However, the lack of corresponding connecting components for the special structure handles in the testing section directly leads to the device's inability to complete the test and makes it difficult to cover the testing needs of handles of various specifications in battery pack production. Utility Model Content

[0005] The purpose of this invention is to provide a battery pack handle pull force testing device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A battery pack handle pull force testing device includes a pull force testing platform. A control panel is fixedly installed at the front end of the top of the pull force testing platform. A base frame is fixedly installed on the top of the pull force testing platform. A fixing plate is fixedly installed on the inner side of the base frame. A connecting column is fixedly connected to the surface of the fixing plate. A fixing base is fixedly connected to the other end of the connecting column. A slide rail is fixedly installed on the top of the base frame. A sliding block is movably installed inside the slide rail. A pull force base plate is fixedly installed at the bottom of the sliding block.

[0008] Also includes:

[0009] A fixing mechanism is provided at the right end of the top of the fixing plate to limit and fix the battery for stability testing.

[0010] A quick-release mechanism is located on one side of the tension base plate to facilitate the disassembly of connecting components, making it easy to replace different connecting parts and adapt to different battery pack handle models.

[0011] A further improvement of the present invention is that the fixing mechanism includes a fixing baffle, a rotating shaft is movably sleeved inside the fixing baffle, a gear block is fixedly connected to one end of the rotating shaft, a transmission plate is meshed at the upper and lower ends of the gear block, and a clamping plate is fixedly connected to one end of the transmission plate.

[0012] A further improvement of this utility model is that: movable blocks are movably installed at both ends of the fixed baffle away from the clamping plate, and clamping blocks are fixedly installed on the surface of the movable blocks.

[0013] A further improvement of the present invention is that: a connecting groove is provided on the top of the clamping block, a plug-in post is movably sleeved inside the connecting groove, and an I-shaped clamping block is fixedly installed on the top of the plug-in post.

[0014] A further improvement of this utility model is that a battery pack is provided inside the fixed base, and a handle is fixedly installed on the right end of the battery pack.

[0015] A further improvement of the present invention is that a fixed clamping arm is fixedly installed on the bottom left side of the tension base plate, and an auxiliary clamping arm is movably installed on the bottom front side of the tension base plate, with a threaded post threadedly connected to the surface of the auxiliary clamping arm.

[0016] A further improvement of the present invention is that the quick-release mechanism includes a connecting block, and the front ends of the fixed clamping arm and the auxiliary clamping arm are provided with mounting grooves. The interior of the mounting groove is detachably connected to one end of the connecting block, and the other end of the connecting block is fixedly connected to a clamping block.

[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0018] 1. This utility model provides a battery pack handle pull force testing device. By rotating the rotating shaft, the operator can drive the gear block fixed at one end of the rotating shaft to rotate synchronously. With the help of the meshing structure between the gear block and the transmission plate, the rotation of the gear block can be smoothly converted into the opposite linear motion of the two transmission plates, thereby driving the two transmission plates to move towards the middle synchronously. The tight fit between the clamping plate and the side wall of the battery pack can form a uniform and stable clamping force on the battery pack, effectively avoiding the lateral displacement of the battery pack due to external force interference during the test, while eliminating shaking phenomenon and ensuring that the battery pack is always in the preset test position.

[0019] 2. This utility model provides a battery pack handle pull force testing device. The operator can select a matching connecting block according to the structure type of the battery pack handle, align the connector of the connecting block with the mounting groove at the front end of the fixed clamping arm and the auxiliary clamping arm, and insert it. Since the auxiliary clamping arm can be installed movably, the width of the handle can be adjusted by rotating the threaded column to adjust the distance between the handle and the fixed clamping arm, so that the connecting blocks on both sides contact the handle, thereby fixing the handle and the clamping block. The device can select a matching connecting block according to the different structure types of the handle, and can flexibly adjust the clamping arm distance to adapt to handles of different widths. It is applicable to battery pack handles of various specifications, thus improving the versatility of the device. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to embodiments:

[0027] like Figure 1-5 As shown, this utility model has the following three specific embodiments.

[0028] Example 1

[0029] This utility model provides a battery pack handle pull force testing device, including a pull force testing test platform 1, a control panel 2 fixedly installed at the front end of the top of the pull force testing test platform 1, a base frame 3 fixedly installed on the top of the pull force testing test platform 1, a fixing plate 4 fixedly installed on the inner side of the base frame 3, a connecting column 5 fixedly connected to the surface of the fixing plate 4, a fixing base 6 fixedly connected to the other end of the connecting column 5, a slide rail fixedly installed on the top of the base frame 3, a sliding block 7 movably installed inside the slide rail, and a pull force base plate 8 fixedly installed at the bottom of the sliding block 7.

[0030] Also includes:

[0031] The fixing mechanism is located at the top right end of the fixing plate 4 and is used to limit and fix the battery for stability testing.

[0032] The quick-release mechanism is located on one side of the tension base plate 8, which is used to easily disassemble the connecting parts, facilitate the replacement of different connecting parts, and adapt to different models of battery pack handles.

[0033] like Figure 1 As shown, the base frame 3 serves as the core support structure of the device. The fixing plate 4 is rigidly connected to the fixing base 6 via the connecting column 5, thus constructing a fixed reference platform for the battery pack. The operator first places the battery pack 61 to be tested into the fixing base 6. The fixing mechanism is activated, and its internal clamping components automatically adjust the clamping stroke according to the external dimensions of the battery pack 61 to prevent the battery pack from becoming loose or shifting during testing. In addition, the operator selects a matching connector according to the type of handle of the battery pack to be tested and inserts the connector into the interface of the quick-release mechanism to complete the rigid connection between the connector and the tension base plate 8. The entire replacement process requires no tools, only manual labor. The test can be completed by simply plugging and unplugging the device. The control panel 2 sends a test command to the device's power system: the electric drive moves the slide rail, causing the sliding block 7 to move linearly along the slide rail. Since the tension base plate 8 is fixedly connected to the sliding block 7, the movement of the sliding block 7 synchronously drives the tension base plate 8, the quick-release mechanism, and the battery pack handle to move in the direction of tension. The tension test module collects tension data in real time: the tension sensor is integrated inside the tension base plate 8. When the handle is subjected to tension, the sensor converts the mechanical signal into an electrical signal, which is amplified and filtered by the signal processing module and then transmitted to the control panel 2. The panel's display screen shows the current tension value, the tension change curve, and the test time in real time.

[0034] Example 2

[0035] The difference from Embodiment 1 is that this embodiment discloses a fixed baffle 64 and a connecting block 86. The fixing mechanism includes a fixed baffle 64, a rotating shaft 65 is movably sleeved inside the fixed baffle 64, a gear block 641 is fixedly connected to one end of the rotating shaft 65, a transmission plate 642 is meshed at the upper and lower ends of the gear block 641, a clamping plate 63 is fixedly connected to one end of the transmission plate 642, a battery pack 61 is disposed inside the fixed base 6, a handle 62 is fixedly installed at the right end of the battery pack 61, a fixed clamping arm 81 is fixedly installed at the bottom left side of the tension base plate 8, an auxiliary clamping arm 82 is movably installed at the bottom front side of the tension base plate 8, a threaded post 85 is threadedly connected to the surface of the auxiliary clamping arm 82, and a quick-release mechanism includes a connecting block 86. The front ends of the fixed clamping arm 81 and the auxiliary clamping arm 82 are both provided with mounting grooves 83. The interior of the mounting groove 83 is detachably connected to one end of the connecting block 86, and a clamping block 84 is fixedly connected to the other end of the connecting block 86.

[0036] like Figure 2 , 4 As shown in Figure 5, the battery pack 61 is placed inside the fixed base 6. The operator rotates the rotating shaft 65, causing the gear block 641 fixed at one end of the rotating shaft 65 to rotate synchronously. Since the upper and lower ends of the gear block 641 mesh with the transmission plate 642 respectively, the rotation of the gear block 641 is converted into the opposite linear motion of the two transmission plates 642, driving the two transmission plates to move synchronously towards the middle, so that the clamping plate 63 fits tightly against the side wall of the battery pack 61, preventing the battery pack 61 from lateral displacement or shaking during the test. Then, according to the structure type of the handle 62 on the battery pack 61, the operator selects the matching connecting block 86, and then aligns the connector of the connecting block 86 with the front of the fixed clamping arm 81 and the auxiliary clamping arm 82. The mounting groove 83 is opened at the end, and the connector is inserted into the mounting groove 83 until the elastic positioning bead is embedded in the positioning hole of the connector of the connecting block 86, thus completing the initial fixation of the connecting block 86 and the clamping arm. Since the auxiliary clamping arm 82 is movably installed at the bottom of the front side of the tension base plate 8, its distance from the fixed clamping arm 81 can be adjusted according to the width of the handle 62. The operator loosens the threaded post 85 and pushes the auxiliary clamping arm 82 to move along the guide rail of the tension base plate 8, so that the connecting blocks 86 on the fixed clamping arm 81 and the auxiliary clamping arm 82 contact the two sides of the handle 62 respectively. After adjustment, tighten the threaded post 85 to lock the position of the auxiliary clamping arm 82 through the thread self-locking, ensuring that the clamping position of the two connecting blocks 86 on the handle 62 is symmetrical, thus achieving the fixation of the handle 62 and the clamping block 84.

[0037] Example 3

[0038] The difference from Embodiment 2 is that this embodiment discloses a movable block 66 and an I-shaped clamping block 69. Movable blocks 66 are movably installed at both ends of the fixed baffle 64 on the side away from the clamping plate 63. A clamping block 67 is fixedly installed on the surface of the movable block 66. A connecting groove is opened on the top of the clamping block 67. A plug-in post 68 is movably sleeved inside the connecting groove. An I-shaped clamping block 69 is fixedly installed on the top of the plug-in post 68.

[0039] like Figure 3 As shown, after the battery pack 61 is clamped and fixed, the movable blocks 66 on both sides are pushed to move towards the middle, so that the clamping block 67 clamps on both sides of the rotating shaft 65. The operator inserts the plug-in post 68 and the I-shaped card block 69 vertically into the connecting groove to form a mechanical self-locking mechanism, thereby achieving longitudinal reinforcement and further increasing the stability of the clamping mechanism.

[0040] The working principle of the battery pack handle pull force testing device will be explained in detail below.

[0041] like Figure 1-5 As shown, the base frame 3 serves as the core support structure of the device. The fixed plate 4 is rigidly connected to the fixed base 6 via the connecting column 5, forming a fixed reference platform for the battery pack. The operator first places the battery pack 61 to be tested into the fixed base 6. The operator then rotates the rotating shaft 65, causing the gear block 641 fixed at one end of the rotating shaft 65 to rotate synchronously. Since the upper and lower ends of the gear block 641 mesh with the transmission plate 642 respectively, the rotation of the gear block 641 is converted into the opposite linear motion of the two transmission plates 642, driving the two transmission plates to move synchronously towards the middle, so that the clamping plate 63 fits tightly against the side wall of the battery pack 61. The distance between the handle 62 and the fixed clamping arm 81 can be adjusted according to the width of the handle 62. The operator then loosens the threaded column 85 and pushes the auxiliary clamping arm 82 to move along the guide rail of the tension base plate 8, so that the connecting blocks 86 on the fixed clamping arm 81 and the auxiliary clamping arm 82 contact the two sides of the handle 62 respectively. After adjustment, tighten the threaded post 85 to lock the position of the auxiliary clamping arm 82 through thread self-locking, ensuring that the clamping positions of the two connecting blocks 86 on the handle 62 are symmetrical. The control panel 2 sends a test command to the power system of the device: the electric drive slide rail runs, driving the sliding block 7 to move linearly along the slide rail. Since the tension base plate 8 is fixedly connected to the sliding block 7, the movement of the sliding block 7 synchronously drives the tension base plate 8, the quick release mechanism and the battery pack handle to move in the direction of tension. The tension test module collects tension data in real time.

[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
