[0045] The embodiment of the present application provides a multimedia storage card 100, which is installed in an electronic device for storing data information. It should be noted that the electronic device can be a digital camera, a drone, a video camera, etc., which is not limited in the present application, and operators in the field can choose according to actual conditions.

[0046] like Figure 1 and Figure 2 As shown, the multimedia storage card 100 includes an integrated circuit module 110 and a housing 120. The integrated circuit module 110 is provided with a plurality of external contact points 114, and the external contact points 114 are used to achieve connection with external electronic devices and data transmission.

[0047] In one embodiment, the housing 120 is configured to be injection molded from a plastic material and encapsulate the integrated circuit module 110 to protect the integrated circuit module 110 , reduce the risk of damage to the integrated circuit module 110 due to external collision, and ensure the normal operation of the multimedia storage card 100 .

[0048] The plastic material may be selected from the group consisting of polycarbonate (PC), polystyrene (PS) or propylene-butadiene-styrene resin (ABS) or other suitable engineering plastics, which is not limited in the present application and can be selected by operators in the art according to actual conditions.

[0049] It should be noted that the use of the injection molding process can not only make the housing 120 have better integrity and stability, but also reduce the risk of cracks or deformation of the housing 120 during use. At the same time, it can also achieve precise size control of the housing 120, which is conducive to the perfect matching of the housing 120 and the integrated circuit module 110, and improve the overall quality and performance of the multimedia storage card 100, that is, improve the waterproof, dustproof and pressure-proof performance of the multimedia storage card 100.

[0050] In one embodiment, a plurality of external contacts 114 are exposed from the housing 120 , so that the multimedia storage card 100 can be connected to an external electronic device and transmit data.

[0051] In summary, the multimedia storage card 100 in the present application has at least the following beneficial effects: on the one hand, compared with the existing storage card assembly shell method, the multimedia storage card 100 in the present application adopts the method of injection molding the shell 120 to form an integrated structure, which can improve the sealing of the shell 120, thereby improving the waterproof, dustproof and pressure-proof performance of the multimedia storage card 100, so that the multimedia storage card 100 can meet the needs of more scenarios.

[0052] On the other hand, compared with the existing ultrasonic pressing method, the multimedia storage card 100 in the present application adopts the method of injection molding the shell 120 to form an integrated structure. The operator does not need to purchase expensive ultrasonic pressing equipment, which greatly reduces the production cost of the multimedia storage card 100.

[0053] In one embodiment, the housing 120 is injection molded on the integrated circuit module 110 to solve the problem of looseness between the housing 120 and the integrated circuit module 11. It can be understood that by injection molding the housing 120 on the integrated circuit module 110, the housing 120 and the integrated circuit module 110 can form an integral structure, which is conducive to ensuring that the housing 120 will not loosen or separate during use, and effectively protecting the integrated circuit module 110 and other components inside.

[0054] In one embodiment, if Figure 2 As shown, the housing 120 includes a first housing 121 and a second housing 122 . The first housing 121 and the second housing 122 are respectively injection molded on the integrated circuit module 110 and cover the integrated circuit module 110 together.

[0055] It can be understood that by adopting the manufacturing method of step-by-step injection molding of the first shell 121 and the second shell 122, it is helpful to ensure the structural stability and consistency of the first shell 121 and the second shell 122. Specifically, by step-by-step injection molding of the first shell 121 and the second shell 122, the molding process of each part can be better controlled, reducing the risk of uneven structure or deformation of the housing 120 caused by one-time injection molding.

[0056] In one embodiment, the first housing 121 or the second housing 122 is provided with a plurality of through holes (not shown), and the plurality of through holes are arranged at intervals. The plurality of external contact points 114 correspond to the plurality of through holes one by one, so as to be exposed to the housing 120 respectively. Through the arrangement of the through holes, the external contact points 114 in the multimedia storage card 100 can be conveniently and quickly connected to external devices; secondly, the risk of short circuit or interference between two adjacent external contact points 114 can be effectively reduced.

[0057] In one embodiment, if Figure 1 and Figure 2 As shown, the integrated circuit module 110 includes a substrate 111, a packaging layer 113 and a plurality of electronic components 112. The plurality of electronic components 112 are mounted on the substrate 111 and are provided with the external contact points 114. The packaging layer 113 is coated on the substrate 111 and the electronic components 112 to ensure the safety and stability of the electronic components 112, and the packaging layer 113 plays an insulating and protective role.

[0058] In one embodiment, the external contact points 114 are exposed on the surface of the packaging layer 113 to facilitate the connection between the multimedia storage card 100 and the electronic device and data transmission. The housing 120 is coated on the packaging layer 113 to provide additional protection for the entire integrated circuit module 110 and enhance the stability and durability of the multimedia storage card 100.

[0059] It should be noted that the arrangement of the substrate 111, the packaging layer 113 and the housing 120 can not only achieve protection and packaging of the electronic components 112, but also facilitate the usability and stability of the external contact points 114, providing a good foundation and guarantee for the normal operation of the multimedia storage card 100.

[0060] In one embodiment, the first housing 121 is injection molded on the packaging layer 113, and the second housing 122 is injection molded on the packaging layer 113 and the first housing 121. Specifically, the operator firstly injection molds the first housing 121 on one side of the packaging layer 113. Then, the operator then injection molds the second housing 122 on the other side of the packaging layer 113, and combines it with the molded first housing 121. In this way, the housing 120 can be completely covered on the integrated circuit module 110.

[0061] Alternatively, in another embodiment, the second housing 122 is injection molded on the packaging layer 113, and the first housing 121 is injection molded on the packaging layer 113 and the second housing 122. Specifically, the operator firstly injection molds the second housing 122 on one side of the packaging layer 113. Then, the operator injects the first housing 121 on the other side of the packaging layer 113 and combines it with the molded second housing 122, thereby completing the housing 120 being entirely covered on the integrated circuit module 110.

[0062] Exemplarily, the process of injection molding the housing 120 on the integrated circuit module 110 in the present application is as follows: the operator first places the packaged integrated circuit module 110 into the mold, and then injection molds the plastic material on one side of the integrated circuit module 110 to form a first housing 121. Then, the operator turns the integrated circuit module 110 including the first housing 121 over, and injection molds the plastic material on the other side of the integrated circuit to form a second housing 122, and the second housing 122 is combined with the first housing 121. In this way, a complete housing 120 can be formed outside the integrated circuit module 110.

[0063] In one embodiment, the packaging layer 113 is configured to be made of packaging material. It should be noted that the packaging material usually has a certain hardness and flexibility, can effectively absorb external impact force, and protect the internal electronic components 112 from damage. In addition, the packaging material also has good insulation performance, which can prevent short circuits or other electrical problems between the electronic components 112.

[0064] In one embodiment, the encapsulation material is epoxy resin. It is worth noting that the encapsulation layer 113 is made of epoxy resin, which can not only provide good mechanical support and protection performance, but also ensure that the electronic component 112 is not damaged during use. At the same time, epoxy resin has high heat resistance and chemical resistance, can remain stable under various environmental conditions, and extend the service life of the product. In addition, since epoxy resin has good fluidity and formability, high precision and complex structural design can be achieved when making the encapsulation layer 113.

[0065] In one embodiment, if Figure 1 As shown, the side wall of the housing 120 is provided with a finger-grip groove 123, which is configured for the user to buckle in with his / her finger. It can be understood that when the multimedia storage card 100 needs to be taken out, the user only needs to buckle his / her finger into the finger-grip groove 123 and apply external force. By providing the finger-grip groove 123, the operator can conveniently and quickly take out the multimedia storage card 100 after injection molding from the injection mold, or take out the multimedia storage card 100 from the electronic device.

[0066] A second aspect of the present application provides a storage device 1, such as Figure 3 As shown, the storage device 1 includes a storage device body 200 and the multimedia storage card 100, and the multimedia storage card 100 is installed in the storage device body 200. The multimedia storage card 100 includes an integrated circuit module 110 and a shell 120. The integrated circuit module 110 is provided with a plurality of external contact points 114, and the shell 120 is configured to be formed by injection molding of a plastic material and is coated on the integrated circuit module 110, and the plurality of external contact points 114 are exposed from the shell 120.

[0067] The storage device 1 in the present application adopts the multimedia storage card 100 described above, and the housing 120 in the multimedia storage card 100 is configured to be made of injection-molded plastic material and covers the integrated circuit module 110 in the multimedia storage card 100. On the one hand, the sealing performance of the housing 120 can be improved, thereby improving the waterproof, dustproof and pressure-proof performance of the multimedia storage card 100, so that the multimedia storage card 100 can meet the needs of more scenarios; on the other hand, the operator does not need to purchase expensive ultrasonic pressing equipment, which greatly reduces the production cost of the multimedia storage card 100.
