DETAILED DESCRIPTION

[0033] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0034] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present invention, its application, or uses.

[0035] Techniques and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the techniques and equipment should be considered part of the specification.

[0036] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0037] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0038] According to an embodiment of the present disclosure, the utility model provides an automatic locking structure for fixing a card to be fixed. Figure 1-7 As shown, an automatic locking structure for fixing a card to be fixed includes a base assembly 1, and also includes:

[0039] The elastic member 2 is used to provide a vertical elastic force, and a first end of the elastic member 2 is connected to the base assembly 1;

[0040] The stopper 3 is connected to the second end of the elastic member 2. The stopper 3 is configured to be able to move upward under the moving thrust of the card 4 to be fixed until the notch 41 of the card 4 to be fixed moves below the stopper 3. Then, the stopper 3 can move downward under the elastic force of the elastic member 2 to clamp the notch 41.

[0041] For example, in the present application, the card to be fixed 4 may be an OCP card, and the elastic member 2 may be a spring. The present application has two groups of automatic locking structures, which are respectively located on the left and right sides of the card to be fixed 4 and are arranged opposite to each other.

[0042] The present application sets an elastic member 2 and a stopper 3. Since the elastic member 2 has elastic force, when the card 4 to be fixed moves to the position of the stopper 3, the stopper 3 moves upward under the moving thrust of the card 4 to be fixed, so that the card 4 to be fixed moves forward while maintaining real-time contact with the stopper 3. During this process, the elastic member 2 is always in a compressed state, and the elastic member accumulates elastic force until the notch 41 of the card 4 to be fixed moves below the stopper 3. The elastic force accumulated by the elastic member 2 is released instantly, and the stopper 3 is prompted to move downward to clamp the notch 41 under the action of the elastic member 2, thereby achieving the purpose of automatically locking the card 4 to be fixed. Therefore, the automatic locking structure of the present application makes it unnecessary to unlock the card 4 to be fixed before installation, and does not require the operator to press and fix it after installation, which reduces the operator's workflow and avoids the risk of damage to the card to be fixed due to missed operations. In addition, the automatic locking structure of the present application is simple in structure and easy to operate, which improves the installation efficiency of the card 4 to be fixed.

[0043] For example, the first end of the elastic member 2 is connected to the base assembly 1 and the second end is connected to the stop block 3. This connection can be a direct connection. For example, the elastic member 2 and the two ends are fixedly connected to the base assembly 1 and the stop block 3 respectively, so that when the stop block 3 is subjected to the moving thrust of the card 4 to be fixed, it can also move upward. At this time, the elastic member is compressed due to its elastic force. At this time, the elastic member stores the elastic force until the notch 41 of the card to be fixed moves below the stop block 3, the elastic member 2 instantly releases the elastic force, so that the stop block 3 moves downward and blocks the notch 41; therefore, this connection method can also achieve the purpose of automatic locking, but when the card to be fixed needs to be removed, it will be slightly difficult. However, by using an external component (such as a screwdriver) to move the elastic member upward and disengage the stop block from the notch 41, the card 4 to be fixed can also be withdrawn. Of course, the above connection can also be that the elastic member 2 is indirectly connected to the base assembly 1 and the stopper 3 through an intermediate medium, such as the connecting assembly 7. For example, when the elastic member is a spring, the connection between the stopper 3 and the base assembly 1 is realized through the intermediate medium of the connecting assembly 7, and the elastic member only needs to be sleeved and connected to the connecting assembly. The elastic member provides elastic force in the vertical direction to realize the automatic locking of the notch 41, and in this way, it is possible to realize a simpler disassembly of the card 4 to be fixed. This connection method will be described in detail in the following content and will not be expanded here.

[0044] In one embodiment, Figure 1-3 , Figure 7As shown, when the stopper 3 and the end of the card to be fixed 4 are in contact, at least one of their contact surfaces is an inclined surface. Specifically, in order to enable the stopper 3 to move upward smoothly under the moving thrust of the card to be fixed 4, the first side surface 31 of the stopper 3 in contact with the card to be fixed 4 is set as an inclined surface. Of course, the end side surface of the card to be fixed 4 in contact with the stopper 3 can also be set as an inclined surface. However, the ends of the cards to be fixed 4 (such as OCP cards) currently on the market generally have an angular structure. Therefore, in order for the automatic locking structure of the present application to be applicable to all cards to be fixed, it is preferred to set the first side surface 31 of the stopper 3 as a smooth inclined surface so that the stopper 3 can move upward under the moving thrust of the card to be fixed 4.

[0045] For example, Figure 8-9 As shown, the card 4 to be fixed is an OCP card and the elastic member 2 is a spring. When the OCP card slides to the right to the position of the stopper 3, the OCP card will give a force to the inclined surface of the stopper 3, and the inclined surface will decompose the force into two directions, rightward and upward. The stopper 3 cannot move to the right, so the stopper 3 will only move upward, and then the OCP card continues to slide to the right. During this process, the upper surface of the OCP card keeps in real-time contact with the end surface of the stopper 3, and the spring is compressed to accumulate elastic force. When the notch 41 of the OCP card to be fixed slides to the lower position of the stopper 3, the elastic force of the spring is instantly released, and the stopper 3 will move downward under the action of the spring to block the notch 41 of the OCP card, thereby fixing the OCP card. Fig.10 The whole installation process does not require the operator to unlock and lock, and the automatic locking function of the OCP card is realized. When the OCP card needs to be removed, the wrench 12 is lifted upward, and the block 3 is separated from the notch 41 of the OCP card and is still as shown in FIG. Fig.11 The status shown can be unlocked and the OCP card can be taken out.

[0046] In one embodiment, Figure 1-7 As shown, in the automatic locking structure of the present application, the base assembly 1 includes a base 11 and a wrench 12, and the wrench 12 has a locked state and an unlocked state. When the wrench 12 is in the locked state, the block 3 is stuck in the notch 41, and when the wrench 12 is in the unlocked state, the block 3 is disengaged from the notch 41.

[0047] For example, an upwardly protruding avoidance groove 111 is formed on the base 11 and a wrench 12 is placed on the avoidance groove 111. The wrench 12 is connected to the block 3 and the elastic member 2 through the connecting assembly 7. The wrench 12 can be switched between a locked state and an unlocked state by lifting or pressing down.

[0048] Specifically, Figure 1-3 , Figure 5-6As shown, a small part of the base 11 is arched upward to form the avoidance groove 111, and the avoidance groove 111 is provided with an avoidance opening 112, and the stopper 3 and the elastic member 2 are accommodated in the avoidance groove 111. The connecting assembly 7 includes a first connecting shaft 71 and a second connecting shaft 72 which are arranged perpendicularly to each other, and the vertically arranged first connecting shaft 71 can movably pass through the avoidance opening 112, the first end of the first connecting shaft 71 is fixedly connected to the stopper 3, and the second end of the first connecting shaft 71 is connected to the transversely arranged second connecting shaft 72 (for example, the second connecting shaft 72 is transversely arranged on the second end of the first connecting shaft 71), and the second connecting shaft 72 is rotatably mounted on the wrench 12. Among them, the first connecting shaft 71 is also provided with an elastic member 2 (spring), and the two ends of the elastic member 2 are respectively in contact with the end surface of the stopper 3 and the top inner surface of the avoidance groove 111. Since the stopper 3 and the elastic member 2 are accommodated in the avoidance groove 111, when the stopper 3 is subjected to the moving thrust of the card to be fixed 4, the avoidance groove 111 prevents the stopper 3 from moving in the direction of the card to be fixed, so that the stopper 3 can only move upward. Fig.10 As shown, when the wrench 12 is placed in a horizontal state, the wrench is in a locked state, at which time the stopper 3 is stuck in the notch 41. When the wrench 12 is lifted upward, the wrench 12 drives the first connecting shaft 71 to move upward in the vertical direction during the lifting process, thereby driving the stopper 3 to disengage from the notch 41. At this time, the wrench 12 is in an unlocked state, as shown in FIG. Fig.11 shown.

[0049] In one embodiment, the base assembly 1 further includes a slide rail 13 for the card 4 to be fixed to slide, and the slide rail 13 is formed in the length direction of the base 11 .

[0050] Specifically, Figure 1-2 As shown, the base 11 is generally in the shape of a long strip, and a convex edge 113 is formed extending outward from the bottom of the base 11 along its length direction, and the convex edge 113 and the side edge 114 of the base form a slide rail 13, and the convex edge 113 is spaced a certain distance from the top of the base 11, so that the two sides of the card 4 to be fixed can be placed on the slide rail 13 and slide along the slide rail 13, so that Figure 2 It can be seen that the side edge 114 of the base, the top of the base 11 and the convex edge 113 form an open groove 14 structure and the open groove 14 is connected to the avoidance groove 111. When the wrench is in a locked state, the free end portion of the stopper 3 is located in the open groove 14, and when the stopper 3 is forced to move upward, it can move vertically upward in the avoidance groove 111. Further, in order to prevent the movement of the stopper 3 from being affected, an opening 131 for avoiding the stopper 3 is also opened on the slide rail 13 corresponding to the position of the stopper 3.

[0051] Alternatively, the slide rail 13 may be formed as follows: an upwardly convex avoidance groove 111 is formed on the base 11, and then an opening groove 14 is opened in the middle of the base 11 along the length direction thereof, the opening groove 14 is arranged perpendicular to the avoidance groove 111 and the two are connected, the opening groove 14 divides the avoidance groove 111 into two parts, the lower part forming the above-mentioned opening 131. The side of the opening groove 14 forms the slide rail 13 for the fixed card 4 to slide.

[0052] For example, in order to facilitate the sliding of the card 4 to be fixed, a slide rail 13 for sliding is formed on the base 11. Therefore, when the card 4 to be fixed slides along the slide rail 13, when the card 4 to be fixed does not touch the stopper 3 and the wrench 12 is in a horizontally placed locked state, the free end of the stopper 3 should be at least partially exposed on the slide rail 13, such as Figure 1-3 As shown, that is, when the wrench 12 is in the locked state, the position of the free end of the stopper 3 should be able to hinder the movement of the to-be-fixed card 4 on the slide rail 13 and move upward under its moving thrust, until the notch 41 of the to-be-fixed card 4 moves below the stopper 3, and the stopper 3 moves downward and extends into the notch 41 to lock the notch 41. Preferably, the free end of the stopper 3 is slightly higher than the convex edge 113, which can make the movement and automatic locking of the stopper 3 more convenient.

[0053] When the card to be fixed 4 slides along the slide rail 13 toward the card connector 5 to be fixed and is plugged into the card connector 5 to be fixed, the notch 41 on the card to be fixed 4 should be just caught and fixed by the stopper 3. Therefore, the installation position of the stopper 3 should be set corresponding to the position where the notch 41 on the card to be fixed is located after the card to be fixed 4 is plugged into the card connector 5 to be fixed.

[0054] For example, the slide rail 13, the base 11, and the avoidance groove 111 can be an integrally formed part, and can be integrally formed by a mold, which is simple and convenient.

[0055] According to one embodiment of the present disclosure, Figure 7-11 As shown, the present application also provides an electronic device, including the automatic locking structure in any of the above embodiments. The electronic device with the automatic locking structure can also achieve the automatic locking effect of the card 4 to be fixed, thereby improving the installation efficiency and removal efficiency of the card 4 to be fixed.

[0056] For example, the electronic device further includes a motherboard 6, the to-be-fixed card connector 5 is welded on the motherboard 6, and the base 11 in the automatic locking structure is fixedly mounted on the chassis 8 by a fixing member, wherein the fixing member can be a threaded member such as a screw, a screw, a bolt, etc. For example, the electronic device includes but is not limited to a desktop computer.

[0057] Taking the electronic device as a desktop computer, the card to be fixed 4 as an OCP card, and the card connector to be fixed 5 as an OCP card connector as an example, the installation and removal process of the OCP card is exemplarily described:

[0058] like Figure 7-8 As shown, the desktop computer is provided with a motherboard 6, an OCP card connector is installed on the motherboard 6, a base 11 is installed on the chassis 8, and the OCP card slides along the slide rail 13 on the base 11 toward the OCP card connector. At this time, the wrench 12 is in a locked state, the wrench 12 is horizontally placed on the avoidance groove of the base 11, and the stopper 3 is exposed on the slide rail 13.

[0059] like Fig. 9 As shown in FIG. 1 , when the end of the OCP card touches the stopper 3, the stopper 3 moves upward under the continuous thrust of the OCP card, and simultaneously drives the first connecting shaft to move upward. At this time, the spring is compressed and accumulates elastic force, and then the OCP card continues to slide to the right. During this process, the upper surface of the OCP card always keeps in contact with the stopper 3, as shown in FIG. Fig. 9 As shown, during this process, the wrench 12 is pushed up by the first connecting shaft and tilted. Until the OCP card slides to the OCP connector position and plugs into it, the notch 41 of the OCP card is just below the stopper 3, and the OCP card no longer has a resisting force on the stopper, so the spring loses the squeezing force of the stopper on it, and the spring instantly releases the elastic force to push the stopper 3 downward to block the notch 41, thereby locking the OCP card, and the wrench 12 returns to the horizontally placed locked state, as shown in FIG. Fig.10 shown.

[0060] like Fig.11 As shown, when the OCP card needs to be unlocked and removed, it is only necessary to lift the wrench 12 upward, and the first connecting shaft drives the stopper to move upward, so that the stopper 3 is disengaged from the notch 41 of the OCP card, and then the OCP card is withdrawn along the slide rail to complete the removal of the OCP card.
