Description

Technical Field

[0001] This utility model relates to the field of indicator technology, specifically to an impact indicator. Background Technology

[0002] During logistics transportation and product warehousing, packages are often damaged due to accidental impacts such as drops and collisions. Existing technologies mostly use single-point impact indicators.

[0003] Point-type impact indicators can record overload impacts in a single direction, but cannot effectively identify multi-dimensional impact events. When packaging boxes are tilted and dropped or subjected to complex collisions, existing devices struggle to accurately determine the direction of impact, leading to difficulties in liability determination and a lack of targeted loss prevention measures.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] During logistics transportation and product warehousing, packages are often damaged due to accidental impacts such as drops and collisions. Existing technologies mostly use single-point impact indicators, where the direction of the impact force is inconsistent with the direction of movement of the impact indicator, making it difficult to trigger.

[0035] Please see Figures 1-10 As shown, this utility model is an impact indicator, comprising:

[0036] The housing structure has a display surface and an adhesive surface opposite to the display surface;

[0037] The shell structure includes a base shell 11 and a cover 12 mounted on the back of the base shell 11. A deep groove 111 is provided on the back of the base shell 11, and a cavity is formed between the deep groove 111 and the cover 12. At the same time, the cover 12 closes the opening of the deep groove 111.

[0038] The base shell 11 is provided with a display surface, which is at least transparent, allowing observation of the internal structure of the deep groove 111.

[0039] A light-shielding layer 15 is provided on the display surface. The light-shielding layer 15 is an opaque sticker or an opaque coating applied to the display surface. A viewing window 151 is provided on the light-shielding layer 15. The viewing window 151 is used to observe changes in the internal structure of the shell structure. The cover 12 is provided with an adhesive surface.

[0040] Both the base shell 11 and the cover 12 can be made of transparent plastic, and the base shell 11 and the cover 12 are fixedly connected by an adhesive.

[0041] The shapes of the base shell 11 and the cover 12 can be changed according to the needs of use.

[0042] like Figures 7-10 As shown, the impact indicator structure has multiple sets and is installed in the cavity provided inside the shell structure. The number of impact indicator structures is even. The distribution of multiple impact indicator structures includes any one of the following: straight line, cross, or star shape. The indicator body 1 is attached to the vertical side of the packaging box.

[0043] When there are two sets of impact indicator structures, the two sets of impact indicator structures are distributed in a vertical line to detect the impact force on the top and bottom sides of the packaging box.

[0044] When there are four sets of impact indicator structures, the four sets of impact indicator structures are distributed in a cross shape to detect the impact force on the upper and lower sides of the packaging box and in the horizontal direction.

[0045] When there are eight sets of impact indicator structures, the eight sets of impact indicator structures are distributed in a star shape to detect the impact force on the packaging box from multiple directions.

[0046] By observing the triggering of the impact indicator structure in different directions, it can be determined which direction the packaging box is overloaded by the impact. In addition, the triggering acceleration of the impact indicator structure can be different to detect different degrees of impact.

[0047] The impact indicator structure includes an indicator block 13 and an elastic member 14 that supports the indicator block 13.

[0048] The stiffness k and initial compression of the elastic arm 141 determine its critical trigger threshold. When the external impact acceleration g reaches or exceeds the set value, the elastic element 14 will deform or displace, thereby driving the indicator block 13 to move and triggering the visual indication.

[0049] When the impact acceleration reaches the trigger threshold of the spring, such as 50g or 100g, the indicator block 13 pushes the spring to deform rapidly, causing it to leave its initial position and displaying the impact event. The entire process is irreversible.

[0050] The mass of the indicator block 13 is m. When it is impacted, it generates an inertial force f = m * a, where f is the deformation of the spring piece and a is the impact acceleration.

[0051] The elastic force of the elastic arm 141 is F, F=k*x, where x is the deformation of the elastic piece;

[0052] When the inertial force f exceeds the retaining force F of the spring, the indicator block 13 moves out of its initial position and triggers the display.

[0053] In addition, ball bearings 19 are installed on both sides of the indicator block 13. The indicator block 13 moves along the side wall of the deep groove 111 by means of the ball bearings 19, thereby reducing the friction during the sliding process.

[0054] Limiting grooves 112 are provided on both opposite sides of the deep groove 111. The end of the elastic member 14 is provided with an elastic arm 141 located in the limiting groove 112. A protrusion 113 is provided on one side of the limiting groove 112, and the protrusion 113 limits the end of the elastic arm 141.

[0055] The limiting groove 112 and the protrusion 113 are transitioned by an inclined surface. The end of the elastic arm 141 falls into the groove through the protrusion 113. The groove and the protrusion 113 are transitioned by a stepped surface. The stepped surface prevents the end of the elastic arm 141 from returning to the limiting groove 112 through the protrusion 113.

[0056] The adhesive structure includes an adhesive layer 16 fixed to the adhesive surface and an anti-adhesive layer 17 disposed on the outside of the adhesive layer 16.

[0057] In use, by peeling off the anti-adhesive layer 17, the adhesive surface of the adhesive layer 16 is exposed. The adhesive surface of the adhesive layer 16 is then attached to the vertical side of the packaging box to complete the fixation of the indicator body 1.

[0058] The cover 12 has a through hole 121. A column 18 passing through the through hole 121 is fixed on the anti-stick layer 17. The column 18 is limited and engaged with the crossbar 142 on the elastic member 14. The end of the indicator block 13 has a bayonet 133. The middle part of the elastic member 14 is installed in the bayonet 133. One side of the indicator block 13 has a first color gamut 131 and a second color gamut 132 displayed through the viewing window 151.

[0059] Unused column 18 limits the elastic element 14 to prevent triggering during the storage of indicator body 1. Before use, tear off the anti-stick layer 17 to remove column 18 and release the limitation on elastic element 14.

[0060] The untriggered indicator body 1 observes the first color gamut 131 through the viewing window 151. After the packaging box is subjected to a gravitational impact, the indicator body 1 is triggered, and the second color gamut 132 is observed through the viewing window 151.

[0061] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
