Description

Technical Field

[0001] This utility model relates to the field of test technology for projectile toys, and in particular to a toy projectile kinetic energy tester. Background Technology

[0002] Projectile toys are among the most popular interactive devices for children's entertainment, widely used in homes, playgrounds, theme parks, and other settings. As an entertainment device based on the principle of kinetic energy release, projectile toys provide children with a highly engaging and dynamic interactive experience thanks to their controllable energy accumulation and instantaneous projection mechanism. However, with the continuous improvement of the design intensity of projectile kinetic energy (the initial projection velocity of some products can reach 10-30 m / s), the safety risks caused by material fatigue or structural failure of kinetic energy components have also increased significantly. Among these, the loss of control over the kinetic energy threshold of the launching mechanism (such as the decay of the spring's elastic modulus, the deterioration of the sealing of the pneumatic energy storage device, etc.) has become a major cause of accidents. Unfortunately, there is currently a lack of tools and instruments on the market that can effectively test the kinetic energy of projectiles such as catapults and slingshots, which have parabolic trajectory. Therefore, this patent application is filed to ensure the kinetic energy safety of projectile toys. Utility Model Content

[0027] Example 1

[0028] The main structure diagram of the toy projectile kinetic energy tester provided by this utility model is shown below. Figure 1 As shown, it includes:

[0029] The system comprises a photoelectric sensor, a test platform, a handwheel, a touchscreen, a fiber optic sensor, a PLC controller, a chassis, a power indicator light, and an emergency stop button. The fiber optic sensor is located inside the chassis. The photoelectric sensor is connected to the fiber optic sensor. The fiber optic sensor is connected to the PLC controller. The PLC controller, a Mitsubishi PLC controller, is located inside the chassis. The touchscreen is embedded on the outer surface of the chassis. The power indicator light is embedded on the outer surface of the chassis. The emergency stop button is embedded on the outer surface of the chassis. The handwheel is connected to the photoelectric sensor and is located below the test platform. It can be used to adjust the distance between the test platform and the photoelectric sensor. Specifically, for different projectile toys, such as projectile guns, catapults, and slingshots, the distance between the test platform and the photoelectric sensor can be flexibly adjusted using the handwheel.

[0030] The photoelectric sensor is an adjustable distance photoelectric sensor.

[0031] The photoelectric sensor is located on the top of the chassis, and there are two pairs of photoelectric sensors distributed in parallel.

[0032] The fiber optic sensor is a high-precision through-beam matrix fiber optic sensor.

[0033] The toy projectile kinetic energy tester also includes a fixed coordinate paper test board as a test background for the projectile. The test board facilitates the observation of the projectile's flight trajectory and impact point, providing data support for subsequent analysis. For example, during testing, grid paper can be attached to the test board, and when a projectile with paint is launched onto the grid paper, the area can be calculated by counting the grids.

[0034] The test platform is equipped with adjustable fixtures.

[0035] The chassis is made of stainless steel or aluminum alloy.

[0036] The touchscreen is either a resistive touchscreen or a capacitive touchscreen.

[0037] The power indicator is an LED indicator.

[0038] The specific operating steps for using the toy projectile kinetic energy tester are as follows (taking a toy gun as an example):

[0039] 1. Measure and record the mass of the projectile to be tested;

[0040] 2. Rotate the emergency stop button clockwise; the power indicator light will illuminate, indicating that the power is on.

[0041] 3. Input the mass of the projectile into the touchscreen software and set the test distance;

[0042] 4. Load the projectile and aim the projectile tool (e.g., toy gun muzzle) at the test area (between the two light beams). After starting to fire, observe the value displayed on the touch screen. If there is no fault display, record the test result. You can record 5 times consecutively. Note that the barrel may not be kept horizontal during firing, causing the projectile to not pass between the two sets of sensors. In this case, there will be no data output. If this happens, you must retest.

[0043] 5. According to the test standard, repeat the test as required in step 4; the test results will be automatically updated during the test.

[0044] 6. Compare the maximum value in the test results with the standard requirement value to determine whether it is qualified;

[0045] 7. After the test is complete, press the emergency stop button to turn off the power. The power indicator light will turn off to indicate that the power is off.

[0046] The above description is only a preferred embodiment of the present utility model, but the scope of protection of the present utility model is not limited thereto. Any modifications, equivalent substitutions and improvements made on the basis of the overall concept of the present utility model shall fall within the scope of protection of the present utility model.
