Description

Technical Field

[0001] This utility model relates to the field of memory card technology, specifically to a flash memory card. Background Technology

[0002] Flash memory cards are independent storage media widely used in mobile phones, digital cameras, laptops, MP3 players, and other digital devices. They are typically presented in card form, hence the name "memory card." Their core principle is to store electronic information using flash memory technology. Because they are generally used as storage media in small digital products such as digital cameras, PDAs, and MP3 players, they are designed to be small, like a card, hence the name flash memory card. With the widespread use of digital products, the demand for flash memory cards is increasing. However, current flash memory cards on the market cannot fully meet this demand. In actual use, due to their small size, they are prone to slippage during insertion and removal, causing inconvenience. Flash memory cards require power to operate, generating heat, and existing flash memory cards generally lack effective heat dissipation designs. If the temperature becomes too high, it will affect their operational stability. Therefore, a new type of flash memory card is needed to meet these needs. Utility Model Content

[0003] The purpose of this invention is to provide a flash memory card to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a flash memory card, comprising a memory card body, an auxiliary protrusion mounted on one end of the memory card body, a plurality of friction grooves formed on one end of the auxiliary protrusion, an installation groove formed on the side of the memory card body, an aluminum alloy heat sink mounted on one end of the installation groove, a heat dissipation groove formed inside the memory card body, and a plurality of heat dissipation particles installed inside the heat dissipation groove.

[0005] Preferably, the memory card body has a card slot on its side, and one end of the card slot is fitted with an angled plate.

[0006] Preferably, the side of the memory card body is provided with multiple anti-slip strips, which are arc-shaped.

[0007] Preferably, one end of the memory card body is provided with a plurality of metal contacts, and one end of the memory card body is provided with a plurality of grooves that are adapted to the metal contacts.

[0008] Preferably, the height of the auxiliary protrusion is greater than the height of the anti-slip strip, and the anti-slip strip is fixed to the outer wall of the memory card body.

[0009] Preferably, the two ends of the heat dissipation particles are connected to the inner wall of the heat dissipation groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] (1) This utility model sets up auxiliary protrusions and friction grooves, etc. The friction grooves on the auxiliary protrusions help the operator to better hold the memory card body. The memory card body can be taken out by pulling one end of the auxiliary protrusion. The side of the memory card body is equipped with aluminum alloy heat sinks, which help to dissipate heat during operation. Through multiple heat dissipation particles installed inside the memory card body, the heat is transferred to both ends for heat dissipation, further improving the heat dissipation effect and making the memory card body more stable when working.

[0012] (2) By setting a slot and an angle, when the metal contact at one end of the memory card body is inserted into the device, the angled end is pressed against the buckle inside the device. After insertion, the buckle springs back and locks into the slot, fixing the position of the memory card body. When holding the side of the memory card body, multiple anti-slip strips rub against the fingers, increasing the friction area and preventing slippage, thus improving the applicability of the memory card body. After insertion, the tiny groove can form a protective barrier, reducing the direct friction between the metal contact and the slot during insertion and removal, preventing oxidation and wear, extending the service life of the metal contact, and improving the applicability of the memory card body.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Example 1: Please refer to Figure 1-4This utility model provides a technical solution: a flash memory card, including a memory card body 1, an auxiliary protrusion 2 installed at one end of the memory card body 1, a plurality of friction grooves 3 formed at one end of the auxiliary protrusion 2, an installation groove 4 formed on the side of the memory card body 1, an aluminum alloy heat sink 5 installed at one end of the installation groove 4, a heat dissipation groove 6 formed inside the memory card body 1, a plurality of heat dissipation particles 7 installed inside the heat dissipation groove 6, a plurality of metal contacts 8 installed at one end of the memory card body 1, a plurality of grooves 12 adapted to the metal contacts 8 formed at one end of the memory card body 1, and the two ends of the heat dissipation particles 7 being connected to... The inner walls of the heat dissipation groove 6 are connected. When the memory card body 1 is inserted, the tiny groove 12 after insertion forms a protective barrier, reducing the direct friction between the metal contacts 8 and the slot during insertion and removal, preventing oxidation and wear, and extending the service life of the metal contacts 8. When the memory card body 1 is running, the aluminum alloy heat sink 5 on the side of the memory card body 1 helps to dissipate heat. Through the multiple heat dissipation particles 7 installed in the heat dissipation groove 6, the heat is transferred to the surface of the memory card body 1 for heat dissipation, further improving the heat dissipation effect and making the memory card body 1 more stable when working.

[0022] Example 2: As Figure 1 and 2 As shown, a card slot 9 is provided on the side of the memory card body 1, and an angled plate 10 is installed at one end of the card slot 9. Multiple anti-slip strips 11 are installed on the side of the memory card body 1. The anti-slip strips 11 are arc-shaped, and the height of the auxiliary protrusion 2 is greater than the height of the anti-slip strip 11. The anti-slip strips 11 are fixed to the outer wall of the memory card body 1. When the memory card body 1 needs to be installed, the friction groove 3 on the side of the memory card body 1 helps the operator to hold it, increasing the friction and thus playing an anti-slip role. The operator pushes the memory card inward along the slot. The card body 1, the bevel 10 on the side of the memory card body 1 will abut against the buckle in the slot. The spring at one end of the buckle is compressed and retracted. When the memory card body 1 is fully pushed in, the buckle rebounds and locks into the card slot 9, fixing the position of the memory card body 1 so that it cannot fall out. When it is necessary to remove the memory card body 1, by pressing one end of the auxiliary protrusion 2, part of the memory card body 1 can be pried out. By pinching one end of the auxiliary protrusion 2 through the friction groove 3, it is easy to pull out the memory card body 1 as a whole. The other features are the same as in embodiment 1.

[0023] The working principle is as follows: When the memory card body 1 needs to be installed, the friction groove 3 on the side of the memory card body 1 helps the operator hold it, increasing friction and thus preventing slippage. The operator pushes the memory card body 1 into the slot, and the angled corner 10 on the side of the memory card body 1 abuts against the buckle in the slot. The spring at one end of the buckle contracts as the memory card body 1 is fully pushed in. When the memory card body 1 is fully pushed in, the buckle springs back and locks into the card slot 9, fixing the position of the memory card body 1 and preventing it from falling out. When it is necessary to remove the memory card body 1, by pressing one end of the auxiliary protrusion 2, part of the memory card body 1 can be pried out and removed through the friction groove 3. Pinch one end of the auxiliary protrusion 2 to facilitate the complete removal of the memory card body 1. When inserting the memory card body 1, the tiny groove 12 after insertion forms a protective barrier, reducing the direct friction between the metal contacts 8 and the slot during insertion and removal, preventing oxidation and wear, and extending the service life of the metal contacts 8. When the memory card body 1 is running, the aluminum alloy heat sink 5 on the side of the memory card body 1 helps to dissipate heat. Through the multiple heat dissipation particles 7 installed in the heat dissipation groove 6, the heat is transferred to the surface of the memory card body 1 for heat dissipation, further improving the heat dissipation effect and making the memory card body 1 more stable when working.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
