Description

Technical Field

[0001] This invention relates to the field of smart terminal technology, and in particular to a card tray connection structure and a smart terminal. Background Technology

[0002] Currently, the SIM card tray insertion and removal method of smartphones on the market is generally achieved by using a SIM card pin to act on a pin hole, and then using a card slot mechanism to insert or remove the SIM card tray. For example, patent application number CN201720580432.3 entitled "A SIM Card Tray and a Mobile Terminal Having the SIM Card Tray" shows the insertion and removal structure of this type of SIM card tray. Specifically, the SIM card tray cover has a through hole corresponding to the position of the operating part, and the mobile terminal housing also has an opening corresponding to the position of the through hole. By using a pin or other object to push against the operating part through the opening and the through hole, the SIM card tray can be removed from the mobile terminal.

[0003] However, with the increasing popularity and development of electronic devices such as mobile phones and smartwatches, waterproofing has gradually become a very important function of smart terminals, especially for outdoor sports enthusiasts who place great importance on the waterproofing of their devices. Existing unlocking methods using a pin require creating a pin hole on the phone's surface, resulting in poor waterproofing in that area. Summary of the Invention

[0019] Optionally, the barrier is a spring with predetermined elasticity; the barrier also includes a fixed end disposed near the opening of the locking groove, the fixed end being fixedly connected in the locking groove;

[0020] The locking groove also includes a second inner wall that connects to the inclined inner wall. An outlet channel is formed between the barrier plate and the second inner wall. A step is also formed between the outlet of the outlet channel and the opening of the locking groove to prevent the limiting post from penetrating into the locking groove from the second side of the barrier plate.

[0021] Optionally, the surfaces of the first inner wall, the second inner wall, and the inclined inner wall are all planes, the angle between the first inner wall and the inclined inner wall is an obtuse angle, and the angle between the second inner wall and the inclined inner wall is an acute angle.

Detailed Implementation

[0035] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0036] Example 1:

[0037] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of a smart terminal when the card tray and slot are inserted and fixed, as provided in this embodiment. Figure 2 This is a schematic diagram of the structural principle of a card holder connection structure provided in this embodiment.

[0038] like Figure 1 and Figure 2 As shown, the smart terminal 10 is a terminal with a card tray 20, and a slot 101 for inserting and fixing the card tray 20 is provided on one side of the smart terminal 10.

[0039] The slot 101 is provided with a card tray connection structure, which includes a telescopic device 200 that can be detachably connected to the card tray 20.

[0040] Specifically, the slot 101 is also provided with an elastic element 220, which is fixedly connected to the telescopic device 200;

[0041] The end of the telescopic device 200 away from the slot of the slot 101 ( Figure 2 The lower end of the telescopic device 200 shown is provided with a locking groove 201, and a barrier piece 230 is fixedly disposed in the locking groove 201. The barrier piece 230 includes a limiting end with predetermined elasticity that extends into the locking groove 201. Figure 2 (The upper end of the barrier 230 shown); a limit post 111 is provided in the slot 101 on the moving path of the barrier 230;

[0042] In this embodiment, as Figure 2 As shown, the barrier 230 is used to divide the locking groove 201 into two travel areas, left and right. Its purpose is to limit the limit post 111 from the first side of the barrier 230 into the locking groove 201 and from the second side of the barrier 230 back to the initial position.

[0043] As an optional implementation, the limiting end abuts against or approaches the first inner wall 2011 of the locking groove 201; however, regardless of which method is chosen, the locking gap 2014 formed by the limiting end and the first inner wall 2011 must be able to lock the limiting end.

[0044] Because when the limiting post 111 is engaged in the locking gap 2014, the elastic element 220 will provide the telescopic device 200 with a force opposite to the insertion direction of the card holder 20. That is, the limiting post 111 will be affected by this force and will press down on the blocking piece 230. Therefore, it is equivalent to suspending the limiting post 111 on the limiting end with a pull. At this time, the telescopic device 200 is locked in the slot 101.

[0045] Furthermore, since this embodiment omits the pin-type unlocking structure, in order to enable the card holder 20 to unlock, the locking groove 201 also includes an inclined inner wall 2013 that connects to the first inner wall 2011 and guides the limiting post 111 to disengage from the card slot gap 2014.

[0046] After the telescopic device 200 is locked in the slot 101, if the card holder 20 is driven to penetrate further into the slot 101 by at least a predetermined unlocking distance, the limiting post 111 can disengage from the locking gap 2014 along the inclined inner wall 2013 and move to the second side of the barrier plate 230, thereby unlocking the telescopic device 200. At this time, if the thrust acting on the card holder 20 is released, the telescopic device 200 will move rapidly towards the slot opening of the slot 101 due to the influence of the elastic force, and the limiting post 111 will return to its initial position rapidly on the second side of the barrier plate 230.

[0047] Among them, the first side and the second side of the barrier 230 are opposite sides of the barrier 230, that is Figure 2 The left and right sides of the barrier 230 shown.

[0048] More specifically, the limiting post 111 is fixedly connected to one end of the fixing rod 110, and the other end of the fixing rod 110 is installed in the slot 101; the limiting post 111 and the fixing rod 110 are arranged in an "L" shape.

[0049] The fixing rod 110 and the barrier plate 230 are staggered to ensure that the fixing rod 110 and the barrier plate 230 do not contact or interfere with each other during the movement of the telescopic device 200.

[0050] More specifically, the slot 101 includes a telescopic groove for inserting the telescopic device 200; the bottom of the telescopic groove is provided with a V-shaped mounting groove 102.

[0051] As an optional implementation, the other end of the fixing rod 110 is rotatably connected to the bottom of the mounting groove 102 via a pin, and a coil spring is sleeved on the pin, with both ends of the coil spring connected to the pin and the fixing rod 110 respectively; or, the fixing rod 110 has a predetermined elasticity, and the other end of the fixing rod 110 is fixedly connected in the mounting groove 102.

[0052] Regardless of the implementation method, the purpose is to limit the initial position of the limiting post 111 to a predetermined small area, so as to ensure that during the insertion and removal of the card holder 20, the limiting post 111 can always penetrate into the locking groove 201 from the first side of the barrier 230 and return to the initial position from the second side of the barrier 230.

[0053] Furthermore, the barrier 230 is a spring with predetermined elasticity; the barrier 230 also includes a fixed end disposed near the opening of the locking groove 201, and the fixed end is fixedly connected in the locking groove 201.

[0054] The locking groove 201 also includes a second inner wall 2012 that connects to the inclined inner wall 2013. An outlet channel is formed between the barrier piece 230 and the second inner wall 2012. A step is formed between the outlet of the outlet channel and the opening of the locking groove 201. The right step surface is perpendicular to the left step surface. Figure 2 The paper protrudes further outward, resulting in a blocking surface 2015 formed at the outlet of the outlet channel. This blocking surface 2015 can effectively prevent the limiting post 111 from penetrating into the locking groove 201 from the second side of the barrier 230.

[0055] More specifically, one end of the elastic element 220 is fixedly connected to the inner wall of the slot 101, and the other end of the elastic element 220 is fixedly connected to the end of the telescopic device 200 near the opening of the slot 101.

[0056] More specifically, the cassette 20 includes a slot portion and a tail portion integrally formed into a T-shape with the slot portion;

[0057] The slot 101 includes a main slot for inserting into the slot portion, two telescopic slots symmetrically opened on opposite sides of the main slot, and an outer slot surrounding the main slot that can be sealed to the tail portion; each telescopic slot is provided with a telescopic device 200.

[0058] The card slot connection structure of this embodiment can be applied to different types of smart terminals, such as mobile phones, tablets, and laptops.

[0059] The smart terminal 10 adopts the card tray connection structure of this embodiment, which eliminates the need to open a pin hole on the card tray 20, thus improving the waterproof performance of the smart terminal. The card tray connection structure achieves the insertion and fixation of the card tray 20 through the cooperation of the elastic element 220, the limiting post 111 and the barrier piece 230. When the card tray 20 needs to be removed, it is only necessary to press the slot 101 a short predetermined distance to quickly release the locking state of the card tray 20. The application is very simple and the user experience is excellent.

[0060] In addition, in this embodiment, "predetermined elasticity" is intended to limit the structural component to a structural component with a certain elasticity that can recover its deformation after the external force is removed. For example, the barrier 230 can be made of metal springs, alloy parts or plastic parts with rigidity and elasticity that meet the application requirements of this embodiment. However, there needs to be a certain limit on the size of this elasticity, that is, it cannot be too "soft" because the barrier 230 needs to play the role of locking the telescopic device 200. This involves the selection of materials in the prior art, so it will not be described in detail here.

[0061] Example 2:

[0062] The difference between this embodiment and Embodiment 1 lies in the arrangement of the elastic element 220; the other structures are largely the same. Please refer to [link / reference needed] for details. Figure 3 , Figure 3 This is a schematic diagram of another card holder connection structure provided in this embodiment.

[0063] Specifically, one end of the elastic element 220 is fixedly connected to the end of the telescopic device 200 away from the slot 101, and the other end of the elastic element 220 is fixedly connected to the bottom of the telescopic groove.

[0064] Compared to Embodiment 1, the elastic element 220 utilizes the elastic force generated by the compression deformation of the elastic element 220, while Embodiment 1 utilizes the elastic force generated by the stretch deformation of the elastic element 220. However, both can provide the telescopic device 200 with a force opposite to the insertion direction of the card holder 20.

[0065] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
