At present, when a designer designs a mounting structure of a circuit board, the mounting structure needs to be considered while satisfying fixing reliability, manufacturability, safety, and ease of mounting. In the related art, the circuit board is usually mounted by fixing the circuit board with screws, which is reliable, but the fixing with screws is complicated in operation, many in process, inconvenient in mounting and dismounting (for example, when the circuit board needs to be repaired or replaced), increases the operation cost, consumes a large amount of metal screws, increases the material cost, and requires screw holes on the circuit board, thereby avoiding the circuit and increasing the design cost. For the circuit board which does not need to be fixed by the screws, the circuit board is often dropped in the transportation or test process due to unreliable fixation, and the structure of some circuit board mounting structures is more complex although the fixation is reliable, which leads to the increase of the production cost. In addition, in a general design, the installation space of the circuit board is matched with the size of the circuit board, and although the design can save space and avoid more gaps between the circuit board and the mounting structure, the applicability of the mounting structure is limited, and the mounting structure is limited to only mount the circuit board with a single size.

Specifically, the guiding structures 11 are disposed on the left and right sides of a mounting structure 100 along a first direction (the X-axis direction shown in fig. 1), and the guiding structures 11 themselves extend along a second direction (the Y-axis direction shown in fig. 1) to guide the circuit board to move back and forth in the second direction. In practical embodiments, the mounting structure 100 may be a top casing or a bottom casing, and the guiding structure 11 may be integrally formed on the top casing and the bottom casing, so as to save the assembly process, reduce the processing difficulty, and be suitable for mass production.

In practical embodiments, the side edges of the circuit board 200 are disposed in the guide slots 110, and the circuit board 200 can be held by the guide structures 11 on two opposite sides by the guide slots 110, so as to perform more significant limiting operation in the first direction and guiding operation in the second direction. In one implementation, the guide groove 110 may be, for example, an inverted trapezoid structure with a large opening and a small bottom, so that the circuit board 200 can be smoothly placed into the guide groove 110 and can be stably clamped after being placed. Of course, the structure of the guide slot 110 is not limited thereto, and in other embodiments, the guide slot may also be a rectangular structure with a uniform bottom, a wedge-shaped structure with a concave shape, and the like. In order to enable the circuit board 200 to be more smoothly placed in the guide groove 110 of the guide structure 11, the initial end of the guide groove 110 of the guide structure 11 in the second direction may be designed as a flaring structure, which may be, for example, an arc transition of a notch towards the top of the guide structure 11, and of course, correspondingly, two corners of the placed end of the circuit board 200 may also be designed as rounded corners, for example. In addition, a buffer pad may be disposed in the guide groove 110 of the guide structure 11, and the buffer pad may be, for example, a rubber pad, an elastic coating or other similar buffer materials, and the buffer pad not only has buffering and shockproof effects, and can better protect the circuit board 200, but also can fully utilize the scalability of the buffer pad, and increase the redundancy of the clamping space between the guide structures 11 on the opposite sides, so as to be applicable to circuit boards of various specifications, and increase the applicability and expandability of the circuit board fixing structure. Furthermore, in an alternative embodiment, regarding the guiding structure 11, a protrusion may be disposed on a side edge of the circuit board 200, and correspondingly, a recess or a limiting hole corresponding to the protrusion may be disposed in the guiding groove 110 of the guiding structure 11, so that, during the process that the circuit board 200 is placed in the guiding groove 110 of the guiding structure 11 and moves along the second direction, the protrusion on the circuit board 200 may cooperate with the recess or the limiting hole in the guiding groove 110 to indicate that the circuit board 200 is pushed into place, and the circuit board 200 is positioned by the cooperation of the protrusion and the recess or the limiting hole. In another alternative embodiment, a recess or a limiting hole may be formed on a side edge of the circuit board 200, and correspondingly, a protrusion corresponding to the recess or the limiting hole may be formed in the guide groove 110 of the guide structure 11.

With continued reference to fig. 2, the guiding structure 11 on either side is a continuous structure disposed along the second direction, but not limited thereto, and in fact, the guiding structure 11 may also be implemented in a discontinuous manner, for example, in other embodiments, the guiding structure 11 on either side may also be implemented in a plurality of discontinuous structures disposed along the second direction, wherein the guiding structure 11 in a short bar structure may have different lengths, and the guiding structures 11 on the two opposite sides may be designed symmetrically (as shown in fig. 4) or asymmetrically (as shown in fig. 5), which should have the same or similar functions as the guiding structure 11 shown in fig. 1.

Referring to FIG. 3, a cross-sectional view taken along line B-B of FIG. 1 is shown. As shown in fig. 1 and 3, the stopping structure 13 is disposed on the mounting structure 100 and located at the end of the guiding structure 11 along the second direction, for corresponding to the front side edge of the circuit board. Specifically, the stopping structure 13 is extended along a first direction (the X-axis direction shown in fig. 1) to stop the circuit board 200 from moving back and forth in a second direction (the Y-axis direction shown in fig. 1). In practical embodiments, the mounting structure 100 may be a top casing or a bottom casing, and the stopping structure 13 may be integrally formed on the top casing and the bottom casing, so as to save the assembly process, reduce the processing difficulty, and be suitable for mass production.

In the practical embodiment, when the front edge of the circuit board 200 abuts against the stop structure 13 during the movement of the circuit board 200 along the second direction by the guide structure 11, the circuit board 200 stops moving.

As shown in fig. 3, the stop structure 13 has a stop groove 130 adapted to the front side edge of the circuit board. In practical embodiments, the front edge of the circuit board 200 is placed in the stopping groove 130 to limit the movement of the circuit board 200. In one implementation, the stopping groove 130 may be, for example, an inverted trapezoid structure with a large opening and a small bottom, so that the circuit board 200 can be smoothly placed into the stopping groove 130 and can be stably clamped after being placed. Of course, the structure of the stopping groove 130 is not limited thereto, and in other embodiments, the stopping groove may also be a rectangular structure with a uniform bottom, a wedge-shaped structure with a concave bottom, or the like. In addition, a buffer pad may be disposed in the stopping groove 130 of the stopping structure 13, and the buffer pad may be, for example, a rubber pad, an elastic coating or other similar buffering materials, and the buffer pad not only has buffering and shockproof effects, and can better protect the circuit board 200, but also can fully utilize the scalability of the buffer pad, and increase the redundancy of the clamping space of the stopping structure 13, so as to be applicable to circuit boards of various specifications, and increase the applicability and expandability of the circuit board fixing structure.

With continued reference to fig. 3, the stopping structure 13 is a continuous structure disposed along the second direction, but not limited thereto, and in fact, the stopping structure 13 may also be implemented in a discontinuous manner, for example, in other embodiments, the stopping structure 13 may also be implemented in a plurality of discontinuous structures disposed along the first direction, wherein the stopping structures 13 may have different lengths (as shown in fig. 6), and should have the same or similar functions as the guiding structure 11 shown in fig. 1.

In addition, a buffer pad may be disposed in the fastening groove 140 of the fixing structure 14, and the buffer pad may be, for example, a rubber pad, an elastic coating or other similar buffer materials, and the buffer pad not only has buffering and shockproof effects, and can better protect the circuit board 200, but also can fully utilize the scalability of the buffer pad to increase the redundancy of the clamping space, so as to be applicable to circuit boards of various specifications, and increase the applicability and expandability of the circuit board fixing structure.

With reference to fig. 3, a retractable spring 142 is disposed between the bottom of the fastener 14 and the guiding structure 11, and the retractable spring 142 is used to drive the fastener 14 to flip relative to the guiding structure 11. In an actual implementation manner, in an initial state, the elastic spring 142 generates a restoring force to make the fastening element 14 in a fastening state, and when the electronic device is used, the fastening element 14 is turned up relative to the guide structure 11 by overcoming the restoring force of the elastic spring 142, so as to present an installation space formed by the guide structure 11 and the stop structure 13, and after the circuit board 200 is moved to the right position along the second direction by using the guide structure 11 and the stop structure 13, the fastening element 14 is released, and the fastening element 14 can be turned down relative to the guide structure by the restoring force of the elastic spring 142 to fasten the rear side edge of the circuit board 200, thereby completing the installation and fixation of the circuit board 200. Meanwhile, aiming at the telescopic springs 142, the scalability of the telescopic springs 142 can be fully utilized, and the redundancy of the clamping space is increased, so that the clamp can be applied to circuit boards with various specifications, and the applicability and the expandability of a circuit board fixing structure are increased.

In addition, other variations are possible with respect to the structure and operation of the fasteners 14 described above.
