Description

Technical Field

[0001] The present invention relates to the technical field of locking structures, and in particular to a buckle structure for an electronic card and an electronic device. Background Art

[0002] With the continuous development and popularization of electronic devices, electronic cards (such as solid-state drives, wireless network cards, memory cards, graphics cards, etc.) are key components for data storage and communication, and are increasingly used in electronic devices. In order to adapt to the production needs of production lines, the requirements for the disassembly and assembly efficiency of electronic cards are also getting higher and higher.

[0003] Electronic cards are generally fixed by connecting one end to the motherboard of the electronic device, while the other end is only fixed with screws. As a result, during the installation and removal of the electronic card, manual tools (such as screwdrivers) are required to lock and remove the screws. This operation is cumbersome and time-consuming, seriously affecting the installation and removal efficiency of the electronic card. Summary of the Invention

[0004] The purpose of the present application is to provide a buckle structure for an electronic card to solve the problem of low efficiency in assembly and disassembly of electronic cards in the prior art; in addition, the present application also provides an electronic device including the buckle structure for an electronic card.

[0005] To achieve this goal, this application adopts the following technical solutions:

[0006] The present application provides a buckle structure for an electronic card, which includes a supporting portion and a clamping portion, wherein:

[0007] A supporting surface is provided at the upper end of the supporting portion in a horizontal direction, and the clamping portion is provided on the supporting surface. The clamping portion includes a first elastic arm and a second elastic arm, the first elastic arm extending upward and provided on the supporting surface, the first end of the second elastic arm is connected to the top end of the first elastic arm, the second end of the second elastic arm extends obliquely downward toward the supporting surface, the top surface of the second elastic arm is an inclined guide surface, and the first elastic arm and the second elastic arm can both generate elastic deformation when subjected to force;

[0008] When one end of the electronic card is engaged, the electronic card abuts against the guide surface of the second elastic arm, pressing the first end of the electronic card downward, causing the second elastic arm to deform toward the first elastic arm, thereby abutting the bottom surface of the end of the electronic card against the support surface, and the second end of the second elastic arm presses against the top surface of the end of the electronic card, thereby locking the electronic card;

[0009] When unlocking, the first elastic arm and the second elastic arm move horizontally away from the electronic card so that the second end of the second elastic arm is separated from the top surface of the electronic card, and the electronic card automatically pops up to achieve unlocking.

[0010] Optionally, the support portion is provided with a C-shaped structure. The support portion includes a bottom plate, a top plate, and a connecting plate, where:

[0011] The bottom plate and the top plate are horizontally spaced apart in the vertical direction, the top plate is located above the bottom plate, and the connecting plate fixedly connects the first end of the bottom plate and the first end of the top plate in the vertical direction. An elastic space is formed between the top plate and the bottom plate, so that the top plate can elastically approach or move away from the bottom plate.

[0012] Optionally, the buckle structure for the electronic card further includes a limiting portion. The limiting portion includes a support plate and a first limiting block, where:

[0013] The support plate is arranged at the end of the bottom plate away from the electronic card in the vertical direction. A first limiting block extends towards the electronic card in the middle of the support plate. A first limiting surface is arranged on the first limiting block towards the electronic card in the horizontal direction. The first limiting surface is configured to limit the electronic card in the horizontal direction.

[0014] Optionally, a second limiting block extends towards the support plate in the horizontal direction on the top plate. The end of the second limiting block close to the support plate forms an interference with the first limiting block in the vertical direction. A second limiting surface is arranged downward on the first limiting block. The second limiting surface is configured to limit the second limiting block in the vertical direction when it abuts against the second limiting block.

[0015] Optionally, a third limiting block extends from the upper end of the support plate in the first direction. A third limiting surface is arranged on the third limiting block towards the first elastic arm in the horizontal direction. The third limiting surface forms an interference with the first elastic arm in the second direction. The third limiting surface is configured to limit the first elastic arm in the second direction.

[0016] Optionally, two limiting portions are arranged on the buckle structure for the electronic card in the first direction. The two limiting portions are symmetrically arranged on both sides of the bottom plate extending in the second direction.

[0017] Optionally, the guiding surface has a trapezoidal structure, and the length of the first end of the second elastic arm in the first direction is greater than the length of the second end of the second elastic arm in the first direction.

[0018] Optionally, the tail of the second end of the second elastic arm bends towards the inner wall of the second elastic arm to form an arc contact surface at the second end of the second elastic arm.

The second end of the electronic card is plugged into the connector, and the first end of the electronic card can be fixed to the mainboard by the snap structure for the electronic card.

[0022] An arc-shaped avoidance groove is provided at the first end of the electronic card toward the first elastic arm, and the avoidance groove is configured to avoid the first elastic arm.

[0023] Compared with the prior art, the buckle structure for an electronic card proposed in this application has the following advantages:

[0024] 1) Through the cooperation of the first elastic arm, the second elastic arm and the supporting surface, elastic deformation is adopted to achieve rapid locking and unlocking of one end of the electronic card without the aid of tools, providing a self-locking buckle structure with a simple structure and easy operation, thereby improving the efficiency of disassembly and assembly of the electronic card.

[0025] 2) By providing a C-shaped support portion, the top plate can be flexibly moved closer to or away from the bottom plate, preventing the electronic card from vibrating too much in the vertical direction, thereby avoiding instantaneous disconnection of the electronic card.

[0026] 3) A first limiting block is provided on the support plate toward the electronic card so that the electronic card is limited when it contacts the first limiting surface on the first limiting block, thereby preventing the card from being ejected.

[0027] 4) The second limiting block is limited in the vertical direction by the first limiting block, so as to limit the top plate in the vertical direction and prevent the top plate from deforming upward.

[0028] 5) By setting a third limit block on the support plate, the first elastic arm is limited in the horizontal direction when the first elastic arm contacts the third limit block, thereby preventing the first elastic arm from excessively deforming when subjected to force, thereby improving the reliability and service life of the snap structure.

[0035] Please refer to Figures 1 to 4As shown in the figure, a buckle structure for an electronic card provided by an embodiment of the present application includes a support portion 10 and a clamping portion 20, where: a support surface 11 is horizontally arranged at the upper end of the support portion 10, the clamping portion 20 is arranged on the support surface 11, the clamping portion 20 includes a first elastic arm 21 and a second elastic arm 22, the first elastic arm 21 is arranged on the support surface 11 extending upward, the first end of the second elastic arm 22 is connected to the top end of the first elastic arm 21, the second end of the second elastic arm 22 extends obliquely downward towards the support surface 11, the top surface of the second elastic arm 22 is an inclined guiding surface 220, and both the first elastic arm 21 and the second elastic arm 22 can generate elastic deformation when stressed; when clamping one end of the electronic card 30, the electronic card 30 abuts against the guiding surface 220 of the second elastic arm 22, pressing down the first end of the electronic card 30 makes the second elastic arm 22 deform towards the first elastic arm 21, and then the bottom surface of the end portion of the electronic card 30 abuts against the support surface 11, and the second end of the second elastic arm 22 presses against the top surface of the end portion of the electronic card 30 to realize the locking of the electronic card 30; when unlocking, the first elastic arm 21 and the second elastic arm 22 move away from the electronic card 30 in the horizontal direction so that the second end of the second elastic arm 22 disengages from the top surface of the electronic card 30, and the electronic card 30 automatically pops up to realize unlocking.

[0036] Specifically, the connection portion between the first elastic arm 21 and the second elastic arm 22 is arranged as an arc structure to enhance the deformation ability of the first elastic arm 21.

[0037] Through the cooperation of the first elastic arm 21, the second elastic arm 22 and the support surface 11, the quick locking and unlocking of one end of the electronic card 30 without the aid of tools are realized by means of elastic deformation, providing a self-locking buckle structure with a simple structure and convenient operation, and improving the disassembly and assembly efficiency of the electronic card 3 .

[0038] In one embodiment, the support portion 10 is arranged as a C-shaped structure, and the support portion 10 includes a bottom plate 12, a top plate 13 and a connecting plate 14, where: the bottom plate 12 and the top plate 13 are horizontally spaced apart in the vertical direction, the top plate 13 is located above the bottom plate 12, the connecting plate 14 is fixedly connected to the first end of the bottom plate 12 and the first end of the top plate 13 in the vertical direction, and an elastic space 15 is formed between the top plate 13 and the bottom plate 12 so that the top plate 13 can elastically approach or move away from the bottom plate 12.

[0039] Specifically, the first ends of the bottom plate 12 and the top plate 13 are both end portions close to the first end of the electronic card 30 in the horizontal direction.

[0040] Specifically, the support surface 11 is the upper surface of the top plate 13.

[0041] Through the cooperation of the bottom plate 12, the top plate 13 and the connecting plate 14, the top plate 13 can elastically approach or move away from the bottom plate 12, preventing the electronic card 30 from having too large an amplitude in the vertical direction to avoid momentary interruption of the electronic card 30.

[0042] In one embodiment, the buckle structure for the electronic card further includes a limiting portion 40. The limiting portion 40 includes a support plate 41 and a first limiting block 42, where: the support plate 41 is arranged vertically at one end of the bottom plate 12 away from the electronic card 30, and a first limiting block 42 extends towards the electronic card 30 in the middle of the support plate 41. A first limiting surface 420 is arranged horizontally towards the electronic card 30 on the first limiting block 42, and the first limiting surface 420 is configured to limit the electronic card 30 in the horizontal direction.

[0043] By arranging the first limiting block 42 on the support plate 41 towards the electronic card 30, when the electronic card 30 contacts the first limiting surface 420 on the first limiting block 42, the electronic card 30 is limited to avoid the occurrence of the card ejection phenomenon.

[0044] In one embodiment, the top plate 13 extends towards the support plate 41 in the horizontal direction and is provided with a second limiting block 130. The end of the second limiting block 130 close to the support plate 41 forms an interference with the first limiting block 42 in the vertical direction. The first limiting block 42 is provided with a second limiting surface 421 facing downwards, and the second limiting surface 421 is configured to limit the second limiting block 130 in the vertical direction when it abuts against the second limiting block 130.

[0045] By the first limiting block 42 limiting the second limiting block 130 in the vertical direction, the top plate 13 is limited in the vertical direction to avoid upward deformation of the top plate 13.

[0046] In one embodiment, a third limiting block 43 extends from the upper end of the support plate 41 in the first direction ( Figure 1 the direction of X in the figure), and the third limiting block 43 is provided with a third limiting surface 430 horizontally towards the first elastic arm 21. The third limiting surface 430 forms an interference with the first elastic arm 21 in the second direction ( Figure 1 the direction of Y in the figure), and the third limiting surface 430 is configured to limit the first elastic arm 21 in the second direction.

[0047] Specifically, the first direction is perpendicular to the second direction.

[0048] Specifically, the upper surface of the third limiting block 43 is set as the SMT suction surface 431 to provide a flat area suitable for the suction nozzle of the mounter to adsorb, ensuring that the mounter can accurately pick up, move and mount the buckle.

[0049] By providing a third limiting surface 430 on the third limiting block 43, when the first elastic arm 21 contacts the third limiting surface 430, the first elastic arm 21 is limited in the second direction, preventing the first elastic arm 21 from being overly deformed when stressed, and improving the reliability and service life of the buckle structure.

[0050] In one embodiment, the buckle structure for the electronic card is provided with two limiting portions 40 along the first direction, and the two limiting portions 40 are symmetrically arranged on both sides of the bottom plate 12 extending along the second direction.

[0051] Specifically, the two limiting portions 40 are arranged at one end of the bottom plate 12 far from the electronic card 30.

[0052] By symmetrically arranging two limiting portions 40 on the bottom plate 12 along the first direction, it is convenient to more evenly limit the position of the electronic card 30, further enhancing the stability of the installation of the electronic card 30, avoiding the installation deviation or looseness of the electronic card 30 caused by uneven force on one side, and at the same time enhancing the limiting strength of the first elastic arm 21, further ensuring the safety of the deformation process of the first elastic arm 21.

[0053] In one embodiment, the guiding surface 220 has a trapezoidal structure, and the length of the first end of the second elastic arm 22 along the first direction is greater than the length of the second end of the second elastic arm 22 along the first direction.

[0054] Specifically, the guiding surface 220 is an isosceles trapezoid.

[0055] By setting the guiding surface 220 as a trapezoidal structure and the length of the first end of the second elastic arm 22 along the first direction being greater than the length of the second end of the second elastic arm 22 along the first direction, while enhancing the connection strength between the first elastic arm 21 and the second elastic arm 22, the stress area of the second end of the second elastic arm 22 is reduced, facilitating the deformation of the second elastic arm 22, enabling the electronic card 30 to be smoothly inserted or ejected, and improving the disassembly and assembly efficiency of the electronic card 30.

[0056] In one embodiment, the tail of the second end of the second elastic arm 22 bends towards the inner wall of the second elastic arm 22 to form an arc contact surface 221 at the second end of the second elastic arm 22, and the arc contact surface 221 is configured to reduce the contact area between the second end of the second elastic arm 22 and the electronic card 30.

[0057] By providing the arc contact surface 221 at the second end of the second elastic arm 22, while reducing the contact area between the second end of the second elastic arm 22 and the electronic card 30 to reduce friction, it avoids damage to the surface of the electronic card 30 by the second elastic arm 22, ensuring the smoothness and safety of the installation of the electronic card 30.

[0058] In one embodiment, the support plate 41, the bottom plate 12, the top plate 13, the connecting plate 14, the first elastic arm 21, and the second elastic arm 22 are integrally formed.

[0059] By adopting an integral molding process, the overall strength and stability of the buckle structure can be improved, the production cost can be reduced, and at the same time, the production efficiency and product quality can be improved.
