Technical Field

[0001] This utility model relates to the field of communication identification card technology, and more specifically to a metal card protective component with engraved patterns on the edge. Background Technology

[0002] Common cards used for communication identification include bank cards, public transport cards, and membership cards. Some special cards are made of metal and often have a series of exquisite patterns engraved on their edges.

[0003] According to the public announcement number: CN213399659U, the public announcement date: 2021-06-08, a dual-interface IC precious metal card is disclosed, including a pattern layer and a protective layer.

[0004] In the prior art, including the aforementioned patents, even metal cards are mainly made of multiple layers of materials. When a metal card with engraved patterns on the edge is dropped or subjected to external pressure, the patterned area is easily damaged by the impact and pressure. Moreover, the damaged metal layers are not easy to recover their deformation, causing gaps at the joints of the multiple layers, until external dirt seeps into the card. Usually, the inside of the card is only glued together, which cannot resist the corrosion and contamination of pollutants, eventually causing the card to be damaged from the inside, and even affecting the electronic components inside the card. At the same time, it also affects the appearance of the card itself. Utility Model Content

[0005] The purpose of this invention is to provide a metal card protective component with engraved patterns on the edge, in order to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A metal card protective piece with an engraved pattern on the edge includes a card with a pattern and a protective sleeve disposed on the edge of the card. The protective sleeve is provided with a protective ring seat, and an inner membrane and an outer membrane distributed in an inner and outer manner are fixedly installed on the side of the protective ring seat.

[0008] By default, the inner membrane is attached to the end face of the card;

[0009] When the protective ring is flipped upside down and placed on the edge of the card, the outer film adheres to the surface of the card, and an opening is formed between the two inner films to create a reverse pattern.

[0010] Preferably, by default, an air chamber is formed between the inner membrane and the outer membrane.

[0011] Preferably, the protective ring seat is provided with an elastic ring that applies pressure to the edge of the card.

[0012] Preferably, the protective ring seat is further provided with a shielding ring arranged opposite to the elastic ring.

[0013] Preferably, a cavity is formed between the shielding ring and the elastic ring.

[0014] Preferably, the central cavity has symmetrically arranged side cavities.

[0015] Preferably, the elastic ring is flipped down to approach the shielding ring, and the central cavity is deflated to supply air to the side cavity.

[0016] Preferably, the side cavity under expansion cooperates with the outer membrane.

[0017] Preferably, a support bar located at the top corner of the card is fixedly installed in the central cavity.

[0018] Preferably, the support strip is a rubber strip.

[0019] In the above technical solution, the metal card protective component with edge engraving provided by this utility model has the following beneficial effects: the inner film provides contact protection when it is attached to the end face of the card and the pattern, while the outer film provides a second layer of protection, further improving the protection against external forces and dirt penetration. When the protective sleeve is used for a long time and the outer surface of the protective ring seat gradually wears down, the protective sleeve can be removed from the card and then flipped open from the inside out, so that the original outer surface of the protective ring seat is in contact with the edge of the card. At this time, the outer surface of the outer film is attached to the end face of the card and the pattern, which extends the protection period of the card and the service life of the card is longer. At the same time, the two inner films form barbed elastic protrusions, which further improves the force buffering effect on the protective ring seat, making the card more intact and maintaining its aesthetic appearance.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] like Figure 1-4 As shown, a metal card protective piece with an edge engraved pattern includes a card 1 with a pattern 11 and a protective sleeve 2 disposed on the edge of the card 1. The protective sleeve 2 is provided with a protective ring seat 21, and an inner membrane 24 and an outer membrane 25 distributed in an inner and outer manner are fixedly installed on the side of the protective ring seat 21.

[0029] By default, the inner membrane 24 is attached to the end face of card 1;

[0030] When the protective ring seat 21 is flipped upside down and placed on the edge of the card 1, the outer film 25 adheres to the surface of the card 1, and an opening is formed between the two inner films 24 to separate the pattern 11.

[0031] Specifically, the protective sleeve 2 and the rest of its components are made of transparent rubber, which is a material based on existing technology and will not be described in detail here.

[0032] Furthermore, the inner membrane 24 and the outer membrane 25 have the same softness so that they can fit more closely to the surface of the card 1 and the pattern 11.

[0033] By placing the protective sleeve 2 over the edge of the card 1 and covering all the patterns 11, the inner film 24 provides contact protection when it adheres to the end face of the card 1 and the patterns 11, while the outer film 25 provides a second layer of protection, further improving the protection against external forces and dirt penetration of the patterns 11. When the protective sleeve 2 has been used for a long time and the outer surface of the protective ring seat 21 has gradually worn down, the protective sleeve 2 is removed from the card 1 and then flipped open from the inside out, so that the original outer surface of the protective ring seat 21 (which needs to be cleaned) is against the edge of the card 1. At this time, the outer surface of the outer film 25 adheres to the end face of the card 1 and the patterns 11, thereby extending the protection period of the card 1 and making the card 1 have a longer service life. At the same time, the two inner films 24 form spiky elastic protrusions, further improving the force buffering effect on the protective ring seat 21, making the card 1 more intact and maintaining its aesthetic appearance.

[0034] As a further embodiment of this utility model, an air chamber 26 is formed between the inner membrane 24 and the outer membrane 25 in the default state.

[0035] Specifically, by default, the ends of the inner membrane 24 and the outer membrane 25 are fitted together, and air can flow into or out of the air chamber 26 from the gaps on the surface of the card 1 or the pattern 11.

[0036] The air chamber 26 absorbs energy and cushions the impact when the card 1 is hit, and the air in the air chamber 26 is discharged along the surface of the card 1, and then the air flows into the air chamber 26 to replenish it.

[0037] As another embodiment further provided in this utility model, the protective ring seat 21 is provided with an elastic ring 22 that applies pressure to the edge of the card 1.

[0038] Specifically, the elastic ring 22 has the greatest elastic force, which is used to keep the protective sleeve 2 tightly attached to the edge of the card 1. The inner membrane 24 near the connection position of the elastic ring 22 has a greater hardness, which is used to limit the fitting of the protective sleeve 2, so as to prevent the protective sleeve 2 from falling off when the elastic force is skewed, and to prevent damage to the other elastic rubber.

[0039] The elastic ring 22 enables the protective sleeve 2 to provide stable binding protection for the card 1, ensuring the stability of the protective sleeve 2 after it is installed on the card 1.

[0040] As another embodiment further provided by this utility model, a shielding ring 23 is also provided on the protective ring seat 21, which is arranged opposite to the elastic ring 22.

[0041] Specifically, the hardness of the shielding ring 23 is equal to the hardness of the connection position of the inner membrane 24, and greater than the hardness of the other positions of the inner membrane 24 and the outer membrane 25. At the same time, the hardness of the outer membrane 25 near the connection position of the shielding ring 23 is also equal to the hardness of the shielding ring 23, so that the protective sleeve 2 after being turned outward can also be stably limited.

[0042] The shielding ring 23 provides wear resistance under normal use, reducing wear on the rest of the protective ring seat 21.

[0043] As another embodiment of the present invention, a cavity 27 is provided between the shielding ring 23 and the elastic ring 22.

[0044] The central cavity 27 is located on the entire protective ring seat 21, which provides gas compression buffer for the protective sleeve 2, so that the card 1 has excellent anti-external pressure effect, and the edge coverage of the card 1 is also larger.

[0045] As another embodiment of this utility model, the central cavity 27 is provided with symmetrically arranged side cavities 28.

[0046] The two side cavities 28 provide lateral cushioning to the annular side of the protective ring seat 21, and the airflow enters the central cavity 27 for absorption, ensuring the protective effect on the card 1.

[0047] As another embodiment of this utility model, the lower elastic ring 22 is flipped closer to the shielding ring 23, and the central cavity 27 is deflated to supply air to the side cavity 28.

[0048] When the central cavity 27 is pressurized, the airflow is sent into the two side cavities 28 to ensure the spacing changes during the buffering process, thus making the energy absorption effect better.

[0049] As another embodiment further provided in this utility model, the lower expansion cavity 28 cooperates with the outer membrane 25.

[0050] When the side cavity 28 expands under normal use, the expansion pressure acts on the air chamber 26. Figure 4 The middle arrow points to the direction of expansion. Therefore, the pressure that spreads around the arc surface of the side cavity 28 will inevitably move closer to the air chamber 26, causing the air chamber 26 to shrink and deflate towards the center of the card 1. As a result, the outer membrane 25 is pushed and the contact range between the end and the card 1 is extended, so that when the protective sleeve 2 is suddenly subjected to force, it can strengthen the protective area of ​​the card 1 surface at the force-bearing position.

[0051] As another embodiment of this utility model, a support bar 29 located at the top corner of the card 1 is fixedly installed in the cavity 27.

[0052] Multiple supports 29 can be used to reinforce the corners of card 1 to protect vulnerable areas of card 1.

[0053] As another embodiment further provided in this utility model, the support strip 29 is specifically a rubber strip.

[0054] The hardness of the support strip 29 is less than that of the shielding ring 23, but greater than that of the inner membrane 24 itself, so that the support strip 29 can deform normally without interfering with the airflow transport inside the cavity 27.

[0055] Working principle: By placing the protective sleeve 2 over the edge of the card 1 and covering all the patterns 11, the inner membrane 24 provides contact protection when it adheres to the end face of the card 1 and the patterns 11, while the outer membrane 25 provides a second layer of protection, further improving the protection against external forces and dirt penetration of the patterns 11. When the protective sleeve 2 has been used for a long time and the outer surface of the protective ring seat 21 has gradually worn down, the protective sleeve 2 is removed from the card 1 and then flipped open from the inside out, so that the original outer surface of the protective ring seat 21 is in contact with the edge of the card 1. At this time, the outer surface of the outer membrane 25 adheres to the end face of the card 1 and the patterns 11, thereby extending the protection period of the card 1 and making the service life of the card 1 longer. At the same time, the two inner membranes 24 form spiky elastic protrusions, further improving the force buffering effect on the protective ring seat 21.

[0056] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
