It should be understood that the specific embodiments described herein are only used to explain the utility model and not to limit the utility model.

[0019] The principles and structures of the utility model will be described in detail below in combination with the drawings and embodiments.

[0020] The existing waterproof technology usually focuses on the part of the SIM card holder to prevent moisture from entering the inside of the mobile phone through the card slot. This includes waterproof sealing rings, SIM card slot covers, and waterproof coatings, etc. These measures can effectively prevent water from entering from the card holder part, but the waterproof design of the ejector rod is still insufficient. The activity of the ejector rod means that it is a dynamic part, which is easy to cause incomplete sealing due to mechanical movement, and thus leads to the penetration of moisture. Therefore, although the waterproof measures of the SIM card holder part are guaranteed to a certain extent, the waterproof design of the ejector rod part is often weak, and there is a risk of water entering the inside of the mobile phone through the joint between the ejector rod and the SIM card holder.

[0021] To this end, as shown in Figure 1 , 3 The utility model provides a waterproof structure of SIM card seat, which includes: shell 1, SIM card seat 2. Specifically, the SIM card seat 2 is installed in the shell 1, and the SIM card seat 2 is a conventional SIM card seat structure in the existing mobile phone, has a spring mechanism, can insert the SIM card holder 4, and the inserted SIM card holder 4 can be ejected by pressing the spring mechanism of the ejector rod 3. Since the structure is a conventional structure and is not the focus of the utility model, it will not be described in detail. A horizontal groove is formed on the outer side of the shell 1 opposite the position of the SIM card seat 2, and the horizontal groove includes a card holder insertion hole and a card removal needle insertion hole 12. The card holder insertion hole is used to insert the SIM card holder 4 corresponding to the SIM card seat 2, and the card removal needle insertion hole 12 is used to receive and guide the ejector rod 3 pressed by the card removal needle when needed. The ejector rod 3 of the SIM card seat 2 extends into the inner opening part of the card removal needle insertion hole 12, and the ejection function of the SIM card holder 4 can be realized by pressing the ejector rod 3 from the outer opening of the card removal needle insertion hole 12. In order to ensure that the SIM card seat 2 can be effectively waterproofed during use, a sealing ring 31 is arranged on the outer periphery of the ejector rod 3. The sealing ring 31 is in close contact with the inner wall of the card removal needle insertion hole 12, and provides sufficient compression force during operation to ensure that water cannot enter the inside of the SIM card seat 2 through the active area of the ejector rod 3.

[0022] The design of the waterproof structure forms a sealed area between the connecting part of the ejector rod 3 and the card needle insertion hole 12, effectively preventing water from penetrating into the inside of the shell 1 through this part, and ensuring the waterproof performance of the SIM card seat 2 in various environments. Especially in the face of humid, splashing water and other external environment, the sealing ring 31 can play a real-time role, avoiding water from entering the inside of the SIM card seat 2, thereby ensuring the normal work of the SIM card and other mobile phone components. Through this structure, the SIM card seat 2 not only has high efficient waterproof ability, but also maintains the normal operability of the ejector rod 3, ensuring the stable ejection function of the SIM card, without causing performance degradation or equipment damage due to water penetration.

[0023] In specific embodiments, as shown in Figure 2 , 3 The ejector rod 3 is in a columnar shape, and an annular groove is arranged on a section of the ejector rod 3 located in the card needle insertion hole 12, and the sealing ring 31 is sleeved in the annular groove. Specifically, the columnar structure of the ejector rod 3 enables it to smoothly move up and down in the card needle insertion hole 12, so as to push the SIM card holder 4 to pop out or be recycled when the card needle is pressed. In order to enhance the waterproof effect, an annular groove is arranged on the outer circumferential surface of the upper section of the ejector rod 3, which enables the sealing ring 31 to be more stably sleeved in the groove, ensuring that the sealing ring 31 remains in the best position during the entire use process and forms an effective seal with the inner wall of the card needle insertion hole 12.

[0024] The sealing ring 31 is in compression contact with the inner wall of the card needle insertion hole 12, effectively preventing water from penetrating into the SIM card seat 2 from the contact area between the ejector rod 3 and the insertion hole. During use, the movement of the ejector rod 3 will not damage the close contact between the sealing ring 31 and the inner wall of the insertion hole, ensuring the durability and reliability of the waterproof structure. The design of the annular groove also enhances the stability of the sealing ring 31, avoiding the problem of slippage or deformation of the sealing ring 31 due to long-term use or external force.

[0025] Preferably, the sealing ring 31 is a rubber ring.

[0026] In specific embodiments, the SIM card holder 4 covers the horizontal groove after being inserted into the card holder insertion hole, and a waterproof sealing ring is arranged on the SIM card holder 4. Specifically, when the SIM card holder 4 is inserted into the card holder insertion hole, the outer edge of the SIM card holder 4 will cover the opening part of the horizontal groove, thereby forming a closed structure. A waterproof sealing ring is arranged on the outer surface of the SIM card holder 4. The sealing ring is located at the outer edge of the SIM card holder 4 and is in contact with the inner wall of the card holder insertion hole of the shell 1. When the SIM card holder 4 is inserted into the card holder insertion hole, the sealing ring will be in compression contact with the inner wall of the insertion hole, forming a tight waterproof barrier to prevent water from entering the SIM card seat 2 through the card holder insertion hole.

[0027] The SIM card holder 4 comprises a card holder plate 41 and a baffle 42, the card holder plate 41 is used to stably place the SIM card and ensure the correct docking of the SIM card with the SIM card seat 2. When the SIM card holder 4 is inserted into the card holder insertion hole of the SIM card seat 2, the end of the card holder plate 41 is tightly combined with the insertion hole of the SIM card seat 2, and the SIM card is fixed in the proper position. The baffle 42 at the end of the card holder plate 41 is used to provide structural support for the card holder plate 41 and help the card holder plate 41 to accurately dock with the SIM card seat 2. A through hole corresponding to the position of the card taking needle insertion hole 12 is formed in the baffle 42 arranged at the end of the card holder plate 41. The through hole allows the card taking needle to be inserted when needed, and the SIM card holder 4 is pushed out or recycled by pressing the top rod 3. A circle of waterproof sealing ring is arranged at the end of the card holder plate 41. The waterproof sealing ring is sleeved on the end of the card holder plate 41, and when the card holder plate 41 is inserted into the SIM card seat 2, the sealing ring is tightly fitted with the card holder insertion hole, so that external substances such as water and dust cannot enter the SIM card seat 2 through the joint between the card holder plate 41 and the card holder insertion hole.
