Description

Technical Field

[0001] The utility model relates to the technical field of smart cards, and in particular to a metal smart card and a smart car key using an automotive-grade chip. Background Art

[0002] Existing smart car keys can be in the form of smart cards, which are convenient for users to carry and use. However, the sensing area of ​​the car key overlaps with the wireless charging area of ​​the mobile phone in the car. When the user uses the smart card car key to start the car, the smart card is not taken away in time. At this time, the user places the mobile phone in the wireless charging area for charging, so that the smart card receives the high-power energy generated by wireless charging, which makes the chip of the smart card heat up or even burn. In addition, the appearance of the smart car key is also damaged.

[0003] There is an existing data card with a metal interlayer, which includes a metal layer, an upper film layer, a lower film layer, and a chip. The upper film layer is located on the upper surface of the metal layer, the lower film layer is located on the lower surface of the metal layer, and the chip is located inside the metal layer. The data card also includes an upper PVC layer and a lower PVC layer. The upper PVC layer is located between the metal layer and the upper film layer, and the lower PVC layer is located between the metal layer and the lower film layer. However, the chip of the data card cannot meet the requirements of the automotive field, and the thickness of the metal layer of the data card is not enough, which makes the data card easily deformed. Utility Model Content

[0004] The first object of the utility model is to provide a metal smart card using an automotive-grade chip with high strength and chip protection.

[0005] The second purpose of the utility model is to use a smart car key using the metal smart card using the automotive-grade chip.

[0006] In order to achieve the above-mentioned first purpose, the utility model provides a metal smart card using an automotive-grade chip, comprising: a card body and an automotive-grade chip, a cavity being arranged inside the card body, and the automotive-grade chip being arranged in the cavity; the card body comprises a metal panel, an absorbing material layer and a polymer material layer, the absorbing material layer is arranged below the metal panel, and the polymer material layer is arranged below the absorbing material layer; an antenna coil layer is laid above the polymer material layer, and a first end of the antenna coil layer is electrically connected to the automotive-grade chip.

[0007] It can be seen from the above scheme that the metal smart card of the utility model is provided with a metal panel, which can largely suppress the card from receiving energy from the wireless charging area, and the metal panel has high structural strength. When the temperature of the smart card body rises due to receiving too much energy, it ensures that the card body of the smart card is not easy to deform, thereby ensuring the stability and reliability of the card. The operating temperature range of the automotive-grade chip is -40°C to 120°C. When the temperature of the card body is high, it can also ensure that the chip is not damaged due to excessive temperature. In addition, the metal smart card has one side of metal and one side of polymer material, allowing users to better distinguish the front and back sides. When the user uses it, he puts one side of the metal panel close to the sensing area of ​​the car key. The metal panel can separate the chip from the sensing area, so that the energy in the wireless charging area will not directly impact the chip, thereby protecting the chip.

[0008] In a further embodiment, the thickness of the metal panel is greater than 40% of the thickness of the metal smart card.

[0009] It can be seen that by setting the thickness of the metal panel to be no less than 40 percent of the thickness of the entire card body, the stability of the card is ensured.

[0010] In a further solution, the absorbing material layer is provided with a first hole, the metal panel is provided with a first groove, and the first hole and the first groove match to form a cavity.

[0011] It can be seen that the automotive-grade chip passes through the absorbing material layer and is partially embedded in the metal panel, but the automotive-grade chip does not pass through the metal panel, so that the automotive-grade chip does not directly contact the wireless charging area.

[0012] In a further solution, the polymer material layer is provided with a second groove, the absorbing material layer is provided with a first hole, the metal panel is provided with a first groove, and the second groove matches with the first hole and the first groove to form the cavity.

[0013] It can be seen from this that when the thickness of the automotive-grade chip is too thick, it can be partially embedded in the polymer material layer, but cannot directly penetrate the metal panel.

[0014] In a further solution, the antenna coil layer is one of a hollow coil, a printed circuit board, and a flexible circuit board.

[0015] It can be seen that the antenna coil layer can be set according to the application scenario.

[0016] In a further solution, a first adhesive layer is provided between the metal panel and the wave absorbing material layer.

[0017] It can be seen that the first glue layer is an adhesive that bonds the metal panel and the absorbing material layer.

[0018] In a further solution, a second adhesive layer is provided between the wave absorbing material layer and the polymer material layer.

[0019] It can be seen that the second glue layer is an adhesive that bonds the polymer material layer and the absorbing material layer.

[0020] In a further solution, at least a portion of the automotive-grade chip is in contact with the metal panel, and an outer surface of the metal panel is exposed to the metal smart card.

[0021] It can be seen that the outer surface of the metal panel is exposed to the metal smart card, which can accelerate the heat dissipation of the automotive-grade chip and make the automotive-grade chip cool down quickly.

[0022] In order to achieve the above-mentioned second purpose, the smart car key provided by the utility model applies the above-mentioned metal smart card using the automotive-grade chip. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 2 It is a schematic diagram of the structural decomposition of an embodiment of a metal smart card using an automotive-grade chip of the utility model.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0026] Metal smart card implementation using automotive-grade chips:

[0027] See also Figure 1 , Figure 1 The metal smart card of the utility model using the automotive-grade chip is a schematic diagram of the structure of the embodiment. The metal smart card includes a card body 1 and an automotive-grade chip 15. The specification of the automotive-grade chip 15 is higher than that of the consumer-grade chip. The operating temperature range of the automotive-grade chip is -40°C to 120°C. When the temperature of the card body is too high, the chip can also be guaranteed not to be damaged due to the high temperature.

[0028] The card body 1 comprises a metal panel 10, an absorbing material layer 13 and a polymer material layer 14. The absorbing material layer 13 is arranged below the metal panel 10, and the polymer material layer 14 is arranged below the absorbing material layer. The polymer material layer can be PVC material.

[0029] The metal panel 10 can largely inhibit the card from receiving energy from the wireless charging area of ​​the car, and the metal panel 10 has high structural strength. When the smart card receives too much energy and the temperature of the card body rises, the smart card body is not easily deformed, thereby ensuring the stability and reliability of the card. The thickness of the metal panel is set to be no less than 40% of the thickness of the entire card body to ensure the stability of the card.

[0030] An antenna coil layer 16 is laid on top of the polymer material layer 14 , and a first end of the antenna coil layer 16 is electrically connected to the automotive-grade chip 15 . The thickness of the metal panel 10 is greater than 40 percent of the thickness of the metal smart card.

[0031] A first adhesive layer 12 is provided between the metal panel 10 and the absorbing material layer 13, and a second adhesive layer 17 is provided between the absorbing material layer 13 and the polymer material layer 14. The first adhesive layer 12 and the second adhesive layer 17 are adhesives. The first adhesive layer 12 bonds the metal panel and the absorbing material layer, and the second adhesive layer 17 bonds the absorbing material layer and the polymer material layer.

[0032] A cavity is provided inside the card body 1, and the automotive-grade chip 15 is provided in the cavity 155. The cavity 155 includes a first hole 152 and a first groove 151. The absorbing material layer 13 is provided with a first hole 152, and the metal panel 10 is provided with a first groove 151. The first hole 152 and the first groove 151 match to form the cavity 155.

[0033] Furthermore, the cavity 155 further includes a second hole 153 and a third hole 154 . The second hole 153 is disposed in the first adhesive layer 12 , and the third hole 154 is disposed in the second adhesive layer 17 .

[0034] The automotive-grade chip 15 passes through the absorbing material layer 13 and is partially embedded in the metal panel 10 , but the automotive-grade chip 15 does not penetrate the metal panel, so that the automotive-grade chip 15 does not directly contact the wireless charging area. The metal panel absorbs the large amount of energy in the wireless charging area, thereby protecting the automotive-grade chip 15 .

[0035] In another embodiment, the polymer material layer 14 is provided with a second groove (not shown in the figure), and the second groove matches the first hole 152 and the first groove 151 to form a cavity 155. When the thickness of the automotive-grade chip 15 is too high, it can be partially embedded in the polymer material layer 14, but cannot directly pass through the metal panel 10, so that the automotive-grade chip does not directly contact the wireless charging area, so that the metal panel can protect the automotive-grade chip 15.

[0036] At least a portion of the automotive-grade chip 15 is in contact with the metal panel 10, and the outer surface of the metal panel 10 is exposed to the metal smart card. The outer surface of the metal panel 10 is exposed to the metal smart card, which can accelerate the heat dissipation of the automotive-grade chip 15 and make the automotive-grade chip 15 cool down quickly.

[0037] One side of the smart card is a metal panel 10, and the other side is a polymer material layer 14, allowing users to better distinguish the front and back sides. When using it, the user places one side of the metal panel 10 close to the sensing area of ​​the car key. The metal panel 10 can separate the automotive-grade chip 15 from the wireless charging area, so that the energy in the wireless charging area will not directly impact the chip, thereby protecting the chip.

[0038] Smart car key implementation example:

[0039] The smart car key in this embodiment uses the metal smart card using the automotive-grade chip described in the above embodiment. The smart car key has high stability and reliability. When the user fails to remove the smart car key from the sensing area in time, it can also ensure that the smart car key will not be heated and burned due to the high-power energy generated in the wireless charging area.

[0040] The above are only preferred embodiments of the present invention, but the design concept of the present invention is not limited thereto. Without departing from the concept of the present invention, more other equivalent embodiments may be included. It is possible for those skilled in the art to make various obvious changes, readjustments and substitutions without departing from the protection scope of the present invention.
