Description

Technical Field

[0001] This utility model relates to the field of wireless communication technology, specifically to an enhanced smart card chip module. Background Technology

[0002] A smart card is a card made by embedding an integrated circuit chip onto a plastic substrate. It has functions such as data storage, processing, and security protection, and can be used in various application scenarios, such as identity recognition, electronic payment, and access control. The smart card and its chip module are closely related. The chip module is the core component of the smart card, containing key components such as a microprocessor and memory. The chip module is like the "brain" of the smart card, responsible for processing various information and instructions. The smart card provides the physical carrier and external interface for the chip module, protects the chip module from external physical damage, and enables data interaction between the chip module and external devices through contact points or antennas.

[0003] Regarding the aforementioned and existing related technologies, the inventors believe that the following drawbacks often exist: Existing smart card casing designs typically use a single material, such as plastic or metal, which performs poorly in resisting external forces. When a smart card is subjected to external impact, the casing is prone to deformation or breakage, increasing the risk of chip damage. During daily use of smart cards, such as frequent insertion and removal of the card reader, the chip module may shift due to vibration or impact, causing the connection between the chip pins and the internal circuitry of the card body to loosen, affecting the normal operation of the chip. Therefore, to address the above problems, an enhanced smart card chip module is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an enhanced smart card chip module, which has the advantages of improved protection and limiting of the chip module, and solves the problems of insufficient protection of smart card chip modules and easy displacement of the chip module under impact, which leads to reduced performance.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an enhanced smart card chip module, comprising a smart card, wherein an installation slot is provided on the outer side of the smart card, a chip module is disposed in the inner cavity of the installation slot, a protective shell for protecting the chip module is disposed on the outer side of the smart card, and a limiting component for limiting the chip module is disposed on the side wall of the inner cavity of the installation slot.

[0006] The effects achieved by the above components are as follows: by setting up a protective shell, the chip module is physically protected, preventing damage to the chip module when the smart card is bent or scratched, which would cause the chip module to malfunction; by setting up a limiting component, the chip module is limited to prevent displacement due to frequent insertion and removal of the smart card, and to prevent the connection between the chip module pins and the internal circuitry of the smart card from becoming loose.

[0007] Preferably, the protective housing includes a frame and a cover fixedly installed on the top of the frame, the surface of which is arc-shaped.

[0008] The effect achieved by the above components is as follows: by setting the frame and the cover to cooperate, it can be used to protect the chip module and prevent the chip module from being damaged by impact. The surface of the cover is set to be arc-shaped, so that when it is impacted by foreign objects, the foreign objects have difficulty finding a point of force and thus sliding, thereby preventing the cover from being severely deformed and preventing the protection effect on the chip module from being reduced.

[0009] Preferably, the shell cover includes an inner layer and an outer layer, the inner layer is used to protect the chip module, the outer layer is used to resist impact, the inner layer is a silicone pad, and the outer layer is an aluminum alloy sheet.

[0010] The aforementioned components achieve the following effects: by setting up the cooperation between the inner and outer layers, they can be used to protect the chip module and prevent the chip module from being damaged by impact. When the smart card is bent or scratched by external force, the hard aluminum alloy sheet on the outer layer resists the external force, and the buffer material silicone pad on the inner layer absorbs the remaining impact force, thereby protecting the chip module from damage.

[0011] Preferably, the top of the smart card has a fixing groove for fixing the frame, and the contact surface between the frame and the fixing groove is provided with protrusions to increase friction.

[0012] The effects achieved by the above components are as follows: by setting a fixing groove for installing and fixing the frame and the cover, the protection effect of the chip module is improved; and by setting a protrusion to increase friction, the stability of the frame installed in the cavity of the fixing groove is improved.

[0013] Preferably, the limiting component includes a spring piece and a slot for fixing the spring piece. A card block is fixedly installed on the surface of the spring piece. A card slot for cooperating with the card block is opened on the surface of the chip module. The surface of the card block is inclined, and the width of the inclined surface is greater than the depth of the card slot.

[0014] The aforementioned components achieve the following effects: by setting a spring to apply elastic force to the card block, the spring is U-shaped, which makes the end of the card block firmly engaged in the inside of the card slot, thus limiting the chip module and preventing the chip module from shifting due to frequent insertion and removal of the smart card, and avoiding loosening of the connection between the chip module pins and the internal circuitry of the smart card. By setting the surface of the card block to be inclined, and the width of the inclined surface being greater than the depth of the card slot, it is convenient to install the chip module.

[0015] Preferably, a heat-conducting sheet is provided at the bottom of the mounting slot cavity for heat conduction, a heat dissipation hole is provided at the bottom of the smart card for heat dissipation, and the bottom of the chip module is bonded to the heat-conducting sheet.

[0016] The effect achieved by the above components is as follows: by setting up heat-conducting plates to conduct heat generated during the use of the chip module, and then dissipating the heat through heat dissipation holes, the heat dissipation effect of the chip module is improved.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention provides physical protection for the chip module by setting a protective shell, preventing damage to the chip module caused by bending or scratching of the smart card, which could lead to malfunction of the chip module. The invention also strengthens the limiting effect on the chip module by setting a limiting component, preventing displacement of the chip module due to frequent insertion and removal of the smart card, and preventing loosening of the connection between the chip module pins and the internal circuitry of the smart card. At the same time, it solves the problems of insufficient protection for smart card chip modules and the chip module's susceptibility to displacement under impact, which leads to reduced performance.

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.

[0026] Please see Figure 1-5An enhanced smart card chip module includes a smart card 1, an installation slot 5 on the outer side of the smart card 1, a chip module 6 disposed in the inner cavity of the installation slot 5, a protective shell 2 for protecting the chip module 6 on the outer side of the smart card 1, and a limiting component 3 for limiting the chip module 6 on the side wall of the inner cavity of the installation slot 5.

[0027] Specifically, the protective housing 2 includes a frame 201 and a cover 202 fixedly installed on the top of the frame 201, the surface of the cover 202 being arc-shaped.

[0028] The frame 201 and the cover 202 work together to protect the chip module 6 from impact damage. The surface of the cover 202 is made arc-shaped so that when it is impacted by a foreign object, the foreign object has difficulty finding a point of force and thus sliding, thereby preventing the cover 202 from being severely deformed and preventing the protection effect on the chip module 6 from being reduced.

[0029] Specifically, the cover 202 includes an inner layer and an outer layer. The inner layer is used to protect the chip module 6, and the outer layer is used for impact resistance. The inner layer is a silicone pad, and the outer layer is an aluminum alloy sheet.

[0030] The inner and outer layers work together to protect the chip module 6 from impact damage. When the smart card 1 is bent or scratched by external force, the hard aluminum alloy sheet on the outer layer resists the external force, while the silicone pad of the inner layer absorbs the remaining impact force, thus protecting the chip module 6 from damage.

[0031] Specifically, the top of the smart card 1 has a fixing groove 4 for fixing the frame 201, and the contact surface between the frame 201 and the fixing groove 4 is provided with protrusions to increase friction.

[0032] The fixing groove 4 is used to install and fix the frame 201 and the cover 202, improve the protection of the chip module 6, and is provided with protrusions to increase friction and improve the stability of the frame 201 installed in the inner cavity of the fixing groove 4.

[0033] Specifically, the limiting component 3 includes a spring piece 301 and a slot 302 for fixing the spring piece 301. A card block 303 is fixedly installed on the surface of the spring piece 301. A slot 304 for cooperating with the card block 303 is opened on the surface of the chip module 6. The surface of the card block 303 is set with an incline, and the width of the incline is greater than the depth of the slot 304.

[0034] The spring piece 301 is used to apply elastic force to the card block 303. The spring piece 301 is a U-shaped spring piece, which makes the end of the card block 303 firmly engaged in the inside of the card slot 304, and plays a limiting role in the chip module 6, preventing the chip module 6 from being displaced due to frequent insertion and removal of the smart card 1, and avoiding loosening of the connection between the pins of the chip module 6 and the internal circuit of the smart card 1. By setting the surface of the card block 303 as a slope, and the width of the slope is greater than the depth of the card slot 304, it is convenient to install the chip module 6.

[0035] Specifically, a heat-conducting plate 7 is provided at the bottom of the inner cavity of the mounting slot 5 for heat conduction, and a heat dissipation hole 8 is provided at the bottom of the smart card 1 for heat dissipation. The bottom of the chip module 6 is bonded to the heat-conducting plate 7.

[0036] The heat-conducting sheet 7 is used to conduct the heat generated by the chip module 6 during use, and then dissipate the heat through the heat dissipation hole 8, thereby improving the heat dissipation effect of the chip module 6.

[0037] In use, the frame 201 and the cover 202 work together to protect the chip module 6 from impact and damage. The spring 301 applies elastic force to the card block 303, so that the end of the card block 303 is firmly engaged in the inside of the card slot 304, which plays a limiting role for the chip module 6.
