Abstract
Description
Technical Field
[0001] This utility model relates to the field of card structure technology, specifically to a card structure with barbs on the surface. Background Technology
[0002] In daily life, people often need to place various cards, such as ID cards, bank cards, and membership cards, in their clothing pockets for easy carrying. However, because these cards are usually thin and smooth, they easily slip out of pockets, causing inconvenience or even financial loss. This problem is particularly prominent when people are very active or when pockets are shallow.
[0003] Traditionally, to prevent cards from slipping, people might use simple physical methods, such as attaching clips or strings to the cards. However, these methods are often inconvenient and can affect the normal use and appearance of the cards. Additionally, there are specially designed card sleeves or card cases on the market. While these can prevent cards from slipping to some extent, they increase the complexity and cost of carrying them.
[0004] In light of this, the industry urgently needs a new card structure that can effectively prevent cards from slipping out of pockets without compromising their normal use and portability. The surface micro-barb structure is an innovative solution addressing this need. By incorporating micro-barbs on the card surface, the friction between the card and the inner wall of the pocket is increased, effectively preventing the card from slipping out. Furthermore, this micro-barb structure is extremely small, causing no significant impact on the card's usability or aesthetics, thus possessing high practical value and promising market application prospects. Summary of the Invention
[0005] To overcome the shortcomings of existing technical solutions, this utility model provides a card structure with a surface micro-barb structure, which can effectively solve the problem of cards easily slipping out of pockets as mentioned in the background technology.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a card structure with barbs on the surface, including a card body, wherein at least one surface of the card body is provided with an array of micro barb structures, the micro barb structures including:
[0007] Main barbs: height 0.1mm to 0.3mm, root diameter 0.05mm to 0.1mm, unidirectionally inclined, with an inclination angle of 15° to 45°;
[0008] Auxiliary barb: 0.05mm to 0.1mm in height, located in the gap area of the main barb;
[0009] Barb reinforcement rib: installed at the base of the barb, with a thickness of 1 / 5 to 1 / 3 of the barb height;
[0010] The spacing between adjacent barbs is 0.5mm to 2mm, and the coverage area accounts for 30%-70% of the single-sided area of the card. The tip of the micro-barb structure is curled towards the card body to form a pre-tight hook topology.
[0011] Furthermore, the micro-barb structure is arranged in an alternating matrix on both sides of the card body, and the tilting directions of adjacent micro-barbs on the same plane are opposite, forming a bidirectional anti-slip structure.
[0012] Furthermore, the card body is provided with several stress-dispersing pits, the pit depth is 0.02mm to 0.05mm, the distribution area covers the root connection of the micro barb structure, and the edge of the pit completely surrounds the root of the micro barb, forming a root stress buffer zone.
[0013] Furthermore, the edge of the recess completely surrounds the micro-barb structure, causing the micro-barb structure to sink as a whole and reducing the thickness of the card structure.
[0014] Furthermore, a protrusion is provided in the recess, and the protrusion is located below the hook tip of the main barb.
[0015] Furthermore, the surface of the micro-barb structure is provided with an antistatic coating.
[0016] Compared with existing technologies, the beneficial effects of this invention are: the micro-barb structure prevents the card from slipping out of the pocket by hooking the textile fibers inside the pocket after it is placed in the pocket. The main function of the micro-barb structure is to effectively hook the textile fibers inside the pocket through its unique barb design. When the card is placed in the pocket, the main barb and the auxiliary barb respectively grab the coarse and fine fibers of the textile, forming multi-point hooking, which greatly increases the friction between the card and the pocket, preventing the card from sliding inside or out of the pocket.
[0017] The design of the indentations effectively disperses and cushions the stress acting on the card. When the card is subjected to external forces, such as friction against the pocket edge when inserted into or removed from a pocket, the stress-dispersing indentations can disperse these stresses from the concentrated micro-barb root area to a wider area of the card surface. This dispersion helps reduce the concentrated stress on the micro-barb roots.
[0018] The protrusion provides a spherical support point for the main barb. When the card enters the pocket, the protrusion makes it easier for the textile fibers to be hooked by the main barb. At the same time, the protrusion increases the contact area between the barb and the fibers, thereby enhancing the stability of the hook. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them.

It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure. Example
[0029] like Figure 1-6 As shown, this utility model provides a card structure with barbs on the surface, including a card body 1, and at least one surface of the card body 1 is provided with an array of micro barb structures 2, the micro barb structures 2 including:
[0030] Main barb 21: Height is 0.1mm to 0.3mm, root diameter is 0.05mm to 0.1mm, unidirectionally inclined, with an inclination angle of 15° to 45°;
[0031] Auxiliary barb 22: with a height of 0.05mm to 0.1mm, located in the gap area of the main barb 21;
[0032] Barb reinforcing rib 23: Located at the root of the barb, with a thickness of 1 / 5 to 1 / 3 of the barb height;
[0033] The spacing between adjacent barbs is 0.5mm to 2mm, and the coverage area accounts for 30%-70% of the single-sided area of the card. The tip of the micro-barb structure 2 curls towards the card body 1 to form a pre-tight hook topology.
[0034] The micro-barb structure 2 is used to prevent cards from slipping out of the pocket by hooking onto the textile fibers inside. The main function of the micro-barb structure 2 is to effectively hook onto the textile fibers inside the pocket through its unique barb design. When a card is placed in the pocket, the main barb 21 and the auxiliary barb 22 respectively grasp the coarse and fine fibers of the textile, forming multiple hooks. This greatly increases the friction between the card and the pocket, preventing the card from sliding inside or out of the pocket.
[0035] The addition of reinforcing ribs 23 enhances the overall strength and stability of the barb structure. This not only ensures that the barb is not easily damaged under stress, but also allows it to better adapt to textiles of different materials and thicknesses, further improving the stability of the card.
[0036] The pre-tightened hook topology design allows the barbs to adhere more tightly to the fabric fibers under stress, reducing card movement and noise in the pocket. This not only improves the user experience but also makes the card easy to remove when needed, without being difficult to detach due to an overly tight hook.
[0037] Due to the flexibility and adaptability of the micro-barb structure 2, this card structure can be widely used in various situations where slippage prevention is required. Whether it is a bank card or ID card used daily, or a work permit or access card that needs to be accessed frequently, this design can improve its stability and portability.
[0038] See Figure 2 and Figure 4 The micro-barb structure 2 is arranged in an alternating matrix on both sides of the card body 1, and the tilting directions of adjacent micro-barbs on the same plane are opposite, forming a two-way anti-slip structure.
[0039] Because the micro-barb structure 2 is arranged in an alternating matrix on both sides of the card and the adjacent barbs are tilted in opposite directions, this design allows the card to effectively grip the textile fibers through the barb structure when subjected to forces from different directions, thereby preventing the card from sliding in different directions. This bidirectional anti-slip capability greatly improves the stability of the card in the pocket and effectively reduces the risk of the card slipping out even during activities or walking.
[0040] The staggered matrix arrangement of the barbs makes the grip force distribution on the card surface more even. No matter where the card is placed in the pocket, the barbs on its surface can form a good hook-and-loop effect with the textile fibers. This even grip force distribution helps reduce card movement in the pocket, further improving the user experience.
[0041] The staggered barb structure can distribute pressure when subjected to force, reducing the stress concentration on individual barbs and thus extending the service life of the barbs. At the same time, the reinforcing ribs also enhance the overall strength and stability of the barb structure, making the card less prone to damage during long-term use.
[0042] See Figure 4 The card body 1 has several stress-dispersing pits 3 with a depth of 0.02mm to 0.05mm. The distribution area covers the root connection of the micro barb structure 2, and the edge of the pit 3 completely surrounds the root of the micro barb, forming a root stress buffer zone.
[0043] The design of the indentation 3 effectively disperses and buffers the stress acting on the card. When the card is subjected to external forces, such as friction with the edge of the pocket when inserted or removed, the stress-dispersing indentation 3 can disperse these stresses from the concentrated micro-barb root area to a wider area of the card surface. This dispersion helps reduce the concentrated stress on the micro-barb root, thereby reducing the risk of structural damage caused by stress concentration.
[0044] By setting stress dispersion pits 3 at the root connection of the micro barbs, a root stress buffer zone can be formed. This buffer zone can enhance the overall stability of the card structure. When subjected to external impact or vibration, the stress dispersion pits 3 can absorb some energy and reduce the impact on the root of the micro barbs, thereby maintaining the integrity of the card structure.
[0045] The design of the recess 3 helps reduce wear and fatigue damage at the root of the microbarbs. By dispersing stress and providing an additional buffer layer, the recess 3 extends the service life of the microbarb structure 2, meaning the card can maintain better performance over long-term use and reduce the need for replacement due to structural damage.
[0046] The presence of the indentation 3 also reduces discomfort when the card is in the pocket. When the card is in close contact with the textile fibers inside the pocket, the indentation 3 provides an extra cushioning layer, reducing noise and discomfort caused by friction.
[0047] See Figures 1 to 4 The edge of the pit 3 completely surrounds the micro barb structure 2, causing the micro barb structure 2 to sink as a whole and reduce the thickness of the card structure.
[0048] By recessing the micro-barb structure 2, the recess 3 design significantly reduces the card's thickness in the micro-barb area. Optimized thickness helps improve product portability and user experience.
[0049] Although the recess 3 design causes the micro-barb structure 2 to sink, it does not weaken its hooking ability. On the contrary, by precisely controlling the depth and shape of the recess 3, it is possible to ensure that the micro-barb maintains sufficient hooking force while reducing friction and abrasion with the textile fibers inside the pocket.
[0050] See Figure 4 A protrusion 4 is provided in the recess 3, and the protrusion 4 is located below the hook tip of the main barb 21.
[0051] The protrusion 4 provides a hemispherical support point for the main barb 21. When the card enters the pocket, the protrusion 4 makes it easier for the textile fibers to be hooked by the main barb 21. At the same time, the protrusion 4 increases the contact area between the barb and the fibers, thereby enhancing the stability of the hook. This helps reduce the card's movement in the pocket and improves reliability during use.
[0052] See Figure 5 The surface of the micro-barb structure 2 is provided with an antistatic coating 5.
[0053] The barbs may increase friction and potentially generate static electricity. The main function of the antistatic coating 5 is to reduce the surface resistance of the material, thereby effectively neutralizing the static electricity generated by friction and preventing it from accumulating and reaching dangerous levels.
[0054] By preventing the generation and accumulation of static electricity, the antistatic coating 5 helps reduce electrostatic interference during card use, thereby improving the card's stability and reliability. This is especially important for cards that require frequent data reading or writing.
