[0002] With economic development and rising living standards, people's demand for entertainment is also increasing. Some projectile toys can effectively relieve stress and enhance entertainment.

[0003] Currently, projectile toys are typically tested for the projectile contact area, such as suction cup bullets and ball-shaped bullets. The testing is usually done manually, and because different toys have different structures and shapes, it is difficult to determine the effective contact area and obtain accurate test results. Therefore, there is a need for improvement. Utility Model Content

It solves the technical problems of existing technologies where the testing of the contact area of ​​projectile toys is usually done manually, which cannot obtain a more accurate effective contact area, and the test variables are numerous, which cannot meet higher testing requirements.

[0005] The above-mentioned technical problem of this utility model is solved by the following technical solution: a contact area testing device for projectile toys, including a workbench, a test box on the workbench, a projectile arm slidingly disposed inside the test box, a projectile contact surface on the inner side of the test box, a contact area testing module disposed on the projectile contact surface, and a feedback module connected to the contact area testing module disposed on one side of the workbench. During testing, the test piece is placed inside the projectile arm, the projectile arm launches the test piece, the test piece is launched onto the projectile contact surface, the contact area testing module on the projectile contact surface calculates the contact area and feeds it back to the feedback module, the feedback module calculates the contact area.

[0006] Preferably, the test chamber has a test base plate on its bottom surface, and a longitudinal groove is formed on the test base plate, along which the ejector arm can slide longitudinally. The ejector arm can be adjusted by sliding longitudinally along the groove on the test base plate according to different testing requirements.

[0007] Preferably, the front end of the test base plate extends to the outside of the test chamber. The length of the test base plate can be adjusted according to actual testing needs. The purpose of extending the test base plate to the outside of the test chamber in this invention is to facilitate placing the test piece inside the ejection arm.

[0008] Preferably, the test base plate has graduations on its surface. The purpose of the test base plate is to facilitate adjustment of the launch arm's forward and backward position according to different needs, enabling precise position adjustment and recording.

[0009] Preferably, the ejection arm is equipped with a storage spring. The storage spring in the ejection arm can launch the test piece onto the ejection contact surface. The ejection arm is an existing structure, so this utility model will not provide a redundant description.

[0010] Preferably, the contact area testing module includes a flexible pressure sensing layer attached to the ejection contact surface, which is composed of an array of miniature pressure sensors. During testing, the test piece is placed inside the ejection arm and ejected onto the surface of the flexible pressure sensing layer on the ejection contact surface under the action of an internal storage spring. The miniature pressure sensors transmit signals to the feedback module under pressure.

[0011] Preferably, the contact area testing module also includes a visual capture camera mounted on top of the test chamber. When the test piece is ejected onto the flexible pressure sensing layer, the visual capture camera captures the contour of the contact area and transmits the contour signal to the feedback module.

[0012] Preferably, the feedback module includes an area calculation module connected to the contact area testing module, and a display connected to the area calculation module. During testing, the test piece is placed inside the ejection arm and ejected onto the surface of the flexible pressure sensing layer on the ejection contact surface under the action of an internal storage spring. The miniature pressure sensor receives pressure and transmits a signal to the area calculation module, which calculates the area and outputs it to the display. When the test piece is ejected onto the flexible pressure sensing layer, a visual capture camera captures the contour of the contact area and transmits the contour signal to the area calculation module.

[0013] Therefore, the contact area testing device for projectile toys of this utility model has the following advantages: it is easy to operate, can effectively reduce manual operation, improve testing efficiency, is applicable to different types of projectile toys, can obtain more accurate test results, and can meet higher testing requirements.
