Description

Technical Field

[0001] This utility model relates to the field of heating pad testing technology, and in particular to a heating pad collision test device. Background Technology

[0002] Traditional heating pad impact testing devices typically consist of a fixed impact platform and pressure plate. Impact tests are conducted through mechanical structures or manual adjustments. During the test, the heating pad is fixed on the test platform, and then a certain impact force is applied to it by a mechanically or manually controlled impact device to simulate the impact scenarios that may be encountered during use. Such devices are designed to verify the performance of the heating pad when subjected to external impacts, including impact resistance, durability, and structural stability.

[0003] However, traditional heating pad impact testing devices typically use horizontal placement for testing, making it impossible to perform impact tests at tilt angles. This makes it difficult to simulate the various complex impact angles and directions encountered in actual use, limiting the comprehensiveness of the test and failing to fully reflect the performance of the heating pad under different impact environments.

[0004] Therefore, those skilled in the art have provided a heating pad impact testing device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a heating pad impact testing device. This device is equipped with a clamping mechanism. Guided by an obliquely placed placement frame and positioning guide rails, a lifting plate can be obliquely lifted from bottom to top under the transmission of a pulley gear. In conjunction with a control motor, a lower limit bar clamps and limits the heating pad placed on the positioning plate, ensuring that the lifting plate can lift the heating pad onto the tray. This ensures that the lifting height remains consistent each time, thereby improving the repeatability and reliability of the operation. It can simulate the collision angle and impact angle of the heating pad when it is impacted, providing a more comprehensive evaluation of the heating pad's impact resistance, thus improving the comprehensiveness and accuracy of the test and ensuring the safety and durability of the heating pad in various usage scenarios.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A heating pad impact testing device includes a fixed frame, a clamping mechanism at the front end of the fixed frame, a placement frame, first pulleys rotatably connected to the lower ends of the outer walls on both sides of the placement frame, positioning guide rails fixedly connected to both sides of the front outer wall of the placement frame, positioning plates slidably connected to the outer walls of the positioning guide rails, first guide blocks fixedly connected to both sides of the rear outer wall of the positioning plates, a transmission module fixedly connected to the center of the upper surface of the placement frame, a servo motor fixedly connected to the input end of the transmission module, a transmission rod fixedly connected to the output end of the transmission module, and second pulleys fixedly connected to both sides of the outer walls of the transmission rod.

[0008] The outer walls of the first and second pulleys are fitted with toothed belts. A lifting plate is fixedly connected to the front end of the outer wall of the toothed belt. A second guide block is fixedly connected to both sides of the middle of the rear outer wall of the lifting plate. A fixed seat is fixedly connected to both sides of the front outer wall of the lifting plate. A rotating motor is fixedly connected to the lower surface of the fixed seat. A limit strip is fixedly connected to the output end of the rotating motor.

[0009] With the above technical solution, the device has a simple structure, and users can easily place the heating pad on the positioning plate and limit the installation by lifting the limiting strip on the plate. By reducing the complex mechanical structure, the operation process is more intuitive and easier to master, and the operation difficulty is reduced.

[0010] Furthermore, the placement frame is fixedly connected to the outer wall of the front end of the fixing frame, and multiple trays are fixedly connected to the inner wall of the placement frame;

[0011] The above technical solution enables the heating pad to be placed relatively stably on the tray for collision detection.

[0012] Furthermore, a base plate is fixedly connected to the lower part of the front outer wall of the placement frame;

[0013] The above technical solution uses a base plate to position and place the heating pad.

[0014] Furthermore, the first guide block is slidably connected to the positioning guide rail;

[0015] The above technical solution enables the positioning plate to be raised in height relatively smoothly.

[0016] Furthermore, the second guide block is slidably connected to the positioning guide rail, and the lifting plate slides outside the positioning guide rail via the second guide block;

[0017] The above technical solution enables the lifting plate to be raised in height relatively smoothly.

[0018] Furthermore, mounting blocks are fixedly connected to both sides of the outer wall at the rear end of the lifting plate;

[0019] The above technical solution allows the lifting plate to be installed and fixed on the toothed belt by setting up an installation block.

[0020] Furthermore, a control cabinet is fixedly connected to the lower end of one side outer wall of the fixed frame, and a control panel is fixedly connected to the upper surface of the control cabinet.

[0021] The above technical solution enables users to operate and adjust the device through the control cabinet and control panel.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model proposes a heating pad collision testing device. The device is equipped with a clamping mechanism. Guided by an inclined placement frame and a positioning guide rail, the lifting plate can be lifted obliquely from bottom to top under the transmission of a pulley gear. With the control of the lower limit bar of the rotating motor, the heating pad placed on the positioning plate can be clamped and limited so that the lifting plate can lift the heating pad and place it on the tray. This ensures that the lifting height is consistent each time, thereby improving the repeatability and reliability of the operation. It can simulate the collision angle and impact angle when the heating pad is hit, and more comprehensively evaluate the impact resistance performance of the heating pad. This improves the comprehensiveness and accuracy of the test, and ensures the safety and durability of the heating pad in various usage scenarios.

The device has a simple structure, and the user can easily place the heating pad on the positioning plate and limit the installation by lifting the limiting strip on the plate. By reducing the complex mechanical structure, the operation process is more intuitive and easier to master, and the operation difficulty is reduced. Attached Figure Description
