Description

Technical Field

[0001] This invention relates to a repeatable quick-release buckle mechanism, and more particularly to an electronic buckle structure that is quick and easy to install and remove, securely positioned, and easy to observe and confirm the assembly status. Background Technology

[0002] M.2 standard solid-state drives (SSDs) are generally available in various lengths, and computer motherboards have multiple mounting holes to accommodate SSDs of different lengths. Currently, the common mounting method is to use screws and studs to secure the SSD to the motherboard. However, this screw and stud combination is not only inconvenient for assembly and disassembly, but also requires pre-installed studs on the motherboard for screw attachment, thus increasing costs. Therefore, improving the assembly efficiency between M.2 standard SSDs and motherboards while reducing overall manufacturing costs is a pressing issue for industry players.

[0003] like Figure 1 , 2 The diagram shows the structure of the utility model patent application No. M657887, "Reusable Quick-Release Snap-on Mechanism," previously filed by the applicant in this case. It mainly includes: a base 1a that can be assembled onto a pre-set substrate 3; wherein the substrate 3 has a positioning groove 31; the base 1a has a columnar support portion 11a, which connects to the middle section of an elongated connecting portion 12a, and one end of the connecting portion 12a has a locking mechanism on one side facing the base 1a. During assembly, the end of the connecting part 12a with the locking protrusion 13a is obliquely inserted into the lower part of one end of the positioning channel 31, and then the other end of the connecting part 12a is passed through the positioning channel 31. The connecting part 12a is then moved away from the locking protrusion 13a, so that the locking protrusion 13a can be inserted upward into one end of the positioning channel 31. The support part 11a is then inserted into the other end of the positioning channel 31, so that the base 1a can be attached and positioned on the substrate 3.

[0004] In the above structure, the base 1a has a recessed accommodating space 14a. The accommodating space 14a has an outwardly protruding support portion 15a on the side facing the card-holding protrusion 13a, and a support surface 16a is formed above the support portion 15a. A sliding clip 20 is engaged in the accommodating space 14a, and the sliding clip 20 can slide back and forth along the direction of the engagement portion 12a. The end of the sliding clip 20 facing the support portion 15a has a pressing portion 202. The pressing portion 202 can slide with the sliding clip 20 and cooperate with the support surface 16a of the support portion 15a to clamp and position the edge of an electronic card 4.

[0005] The above structure has the following disadvantages in practical applications:

[0006] 1. Since the base 1a is assembled on the substrate 3, the locking protrusion 13a is inserted into one end of the positioning groove 31 from the bottom of the substrate 3 to form a positioning effect. Therefore, to confirm whether the locking protrusion 13a is indeed assembled in the predetermined position, a simpler way is to look at the positioning groove 31 from above the substrate 3 to confirm whether the locking protrusion 13a is indeed assembled in the default fixed position in the positioning groove 31. However, if this purpose is to be achieved, the support portion 15a of the base 1a must generally be designed to protrude outward by a shorter length to show that the positioning groove 31 has one end of the locking protrusion 13a. In this way, it will obviously cause insufficient depth space for the support surface 16a to support the end of the electronic card 4, which will easily cause the end of the electronic card 4 to be unstable and wobbly when it is snapped, and even easy to slip off during assembly. This creates a deficiency that is difficult to balance in terms of design and application.

[0007] 2. Since the support part 11a is in the shape of a straight column and the connecting part 12a extends horizontally, when the base 1a is positioned on the substrate 3, the end of the connecting part 12a away from the locking protrusion 13a is flat against the bottom surface of the substrate 3 and does not produce any elastic clamping effect on the substrate 3.

[0008] 3. Since the support part 11a is inserted into the end of the positioning groove 31, and the end of the connecting part 12a away from the locking protrusion 13a is flat against the bottom surface of the substrate 3; therefore, when the base 1a is removed from the substrate 3, when the base 1a is tilted downward at the end close to the locking protrusion 13a (causing the locking protrusion 13a to disengage from the positioning groove 31), it is very easy for the part of the connecting part 12a that connects to the support part 11a to break due to lack of movable space.

[0009] Please refer to Figure 3 As shown, this is for Figure 1 , 2 Another variation of the disclosed structure includes a base 1b and a sliding clamp 20 as described above. The base 1b has a structure similar to that of the aforementioned base 1a, except that the base 1b has a support portion 15b that protrudes outward and has a longer length, so that the support portion 15b has a deeper support surface 16b for supporting one end of the electronic card 4, so that the sliding clamp 20 can cooperate with the support surface 16b to form a more stable clamping and positioning of the electronic card 4.

[0010] However, this structure with a longer outward-protruding support portion 15b can easily obscure the positioning channel 31, making it impossible to directly view and confirm from above the substrate 3 whether the locking protrusion 13a is indeed assembled in the positioning position.

[0011] In view of the above-mentioned shortcomings of common electronic card clip devices, the inventors researched ways to improve these shortcomings, and finally the present invention came into being. Summary of the Invention

[0082] Please refer to Figures 4 to 6As shown, the main structure of the present invention includes: a latching mechanism A, which is composed of a base 1 and a clamping member 2; wherein the bottom of the base 1 has a main positioning part 11 and a secondary positioning part 15, which can be respectively engaged with the corresponding positioning groove 31 and positioning hole 32 on a base plate 3; the main positioning part 11 has a curved support part 111, and the periphery of the support part 111 near the base 1 is provided with an annular flange 116, and the end of the support part 111 away from the base 1 is connected to an elongated elastic... The middle section of the connecting part 112 has an extension part 114 and a clip part 115 at both ends. The extension part 114 has a locking protrusion 113 on the side facing the base 1. The secondary positioning part 15 has an elastic piece 151 extending parallel to the clip part 115. A positioning protrusion 152 protruding towards the connecting part 112 is provided at the end of the elastic piece 151. The two ends of the positioning channel 31 are respectively provided with a locking part 311 corresponding to the locking protrusion 113 and a top abutting part 312.

[0083] In the above structure, the height of the support part 111 is slightly greater than the thickness of the substrate 3, and the angle α between the support part 111 and the bottom surface of the base 1 is less than 90 degrees, so that the support part 111 extends obliquely toward the side of the magazine part 115. At the same time, the angle β between the support part 111 and the magazine part 115 is less than 90 degrees, so that the magazine part 115 extends obliquely toward the bottom surface of the base 1.

[0084] The base 1 has a recessed accommodating space 12 at its top. One end of the accommodating space 12 (corresponding to the magazine portion 115) has an inner stop surface 13, and the other end away from the inner stop surface 13 has an end opening 14 corresponding to the extension portion 114. A support portion 16 is provided outside the end opening 14. The top of the support portion 16 has a support surface 161, and the outer edge of the support portion 16 has a slope 162 that is obliquely concave towards the support portion 111 and the connecting portion 112. At least one side (which may be both sides) of the accommodating space 12 has a parallel extending guide portion 121 and a limiting portion 122. In this embodiment, the guide portion 121 and the limiting portion 122 are hollowed-out long guide grooves, and the guide portion 121 is connected to a guide groove 123 upward and outward, and the limiting portion 122 is connected to a limiting guide groove 124 upward and outward.

[0085] The clamp 2 is partially disposed within the receiving space 12. The clamp 2 has a push-pull portion 25 exposed outside the top of the receiving space 12. The side of the clamp 2 extending into the receiving space 12 has a guided portion 21 and a limiting portion 22, respectively connected to the guide portion 121 and the limiting portion 122. The guided portion 21 is integrally formed on the clamp 2 and can extend into the guide portion 121. The guide 21 forms a sliding guide, and the limited part 22 can extend into and hook into the limited part 122. In addition to forming a sliding guide, it can also prevent the clamp 2 from loosening outward from the receiving space 12. In this embodiment, the guided part 21 can be a convex shaft that can extend into the guide part 121 (long guide groove), and the limited part 22 can be a hook-shaped structure that can extend into and hook into the limited part 122 (long guide groove).

[0086] The clamp 2 is provided with a curved elastic portion 23 extending toward the inner stop surface 13. The curved elastic portion 23 has a free end 231 that can elastically abut against the inner stop surface 13. The end of the clamp 2 away from the inner stop surface 13 is provided with a pressing portion 24. The pressing portion 24 protrudes outward from the end opening 14, and a downwardly sloping guide surface 241 is provided above the pressing portion 24.

[0087] Please refer to Figures 6 to 8 As shown, during assembly, the clamping part 2 extends into the guide part 121 (long guide groove) and the limiting part 122 (long guide groove) through the guide groove 123 and the limiting guide groove 124 respectively, so that the clamping part 2 can quickly and easily form a slidable connection with the base 1.

[0088] The base 1 can extend obliquely into the positioning groove 31 below the locking part 311 (e.g., the extension 114). Figure 6 (As shown); then the magazine portion 115 of the connecting portion 112 passes through the positioning groove 31, and the base 1 is translated toward the end of the top 312 (away from the locked portion 311) (as shown). Figure 7 As shown), the support portion 111 abuts against the top 312 with the annular flange 116, and the locking protrusion 113 is inserted upward into the locking portion 311 to form a positioning. At the same time, the obliquely extended spring clip portion 115 can elastically press and hold the bottom of the substrate 3, and the part of the spring clip portion 115 that connects with the support portion 111 can form a gap B between it and the bottom surface of the substrate 3. The positioning protrusion 152 can be inserted into the positioning hole 32 to form a positioning mechanism that assists the main positioning portion 11, so that the base 1 can be stably attached and positioned on the substrate 3 (as shown). Figure 8 (As shown).

[0089] In the above structure, by means of the inclined surface 162 structure design of the outer edge of the support part 16 concave towards the support part 111 and the connecting part 112, when the base 1 is connected and positioned on the substrate 3, the locking part 311 of the positioning channel 31 is not covered by the support part 16 and is exposed to the outside; therefore, it is convenient to observe from above the positioning channel 31 of the substrate 3 whether the locking protrusion 113 is indeed locked into the locking part 311, and thus confirm whether the base 1 has been properly connected and positioned on the substrate 3.

[0090] In the above structure, if it is necessary to detach the latching mechanism A from the base plate 3, the base 1 can be pressed obliquely first to disengage the latching protrusion 113 from the latched part 311. At this time, the gap B provides space for the movement of the magazine part 115 to prevent the magazine part 115 from breaking. Then, the latching mechanism A is pushed toward the latched part 311 so that the annular flange 116 moves away from the abutted top 312, thus detaching the latching mechanism A. Figure 6 The sample is taken out from the positioning channel 31 in the opposite direction shown.

[0091] Please refer to Figures 9 to 12 As shown, in practical applications, if an electronic card 4 (which can be a solid-state drive) is to be assembled, the electronic card 4 with its pinned electrical connection end 42 can be first inserted into a terminal block 40. Then, the locking end 41 of the other end of the electronic card 4 is pushed downward and contacts the guide slope 241 of the clamping member 2 (e.g., ...). Figure 9 (As shown); causing the clamping member 2 to slide toward the inner stop surface 13 and compressing the bent elastic part 23 to produce elastic deformation (as shown). Figure 10 (as shown); In a feasible embodiment, the edge of the card terminal 41 of the electronic card 4 is provided with an arc-shaped notch 411, and a corresponding arc-shaped edge 242 is provided around the pressing part 24. When the edge of the electronic card 4 slides down the guide slope 241 through the pressing part 24, the notch 411 can fit the arc-shaped edge 242 to form a guide effect that is not easy to shake.

[0092] When the card-attached end 41 of the electronic card 4 is pressed down through the pressing part 24 onto the support surface 161 of the support part 16, the longer support surface 161 provides stable support for the edge of the electronic card 4. The clip 2, under the elastic action of the bending elastic part 23, springs back to its initial position before movement, allowing the pressing part 24 to be engaged above the edge of the card-attached end 41 (notch 411) of the electronic card 4. This clamps and positions the card-attached end 41 of the electronic card 4 in a usable position between the support part 16 and the pressing part 24 (e.g., ...). Figure 11 (As shown).

[0093] Conversely, if it is desired to disassemble the assembled electronic card 4, an external force can be applied to the push-pull part 25, causing the clamping member 2 to slide towards the inner stop surface 13 (away from the electronic card 4) and compress the bending elastic part 23 to produce elastic deformation. At this time, the pressing part 24 disengages from the edge of the locking end 41 (notch 411), releasing the pressure on the electronic card 4. Then, the electronic card 4, through the elasticity of the electrical connection end 42 applied by the terminal base 40, can cause the locking end 41 to disengage from the support surface 161 and tilt upwards to an easily detachable position (such as...). Figure 12 As shown); when the force acting on the push part 25 disappears, the clamp 2 is elastically acted upon by the bending elastic part 23 and can spring back to its initial position before moving.

[0094] The structure described above in this invention has the following characteristics:

[0095] 1. The support portion 16 is designed with a slope 162 that is concave towards the support portion 111 from the outer edge, which exposes the locking portion 311 of the positioning groove 31. This allows for easy viewing of the combination state of the locking protrusion 113 in the locking portion 311 from above the substrate 3, to confirm whether the base 1 has been properly engaged and positioned on the substrate 3, thus facilitating production and assembly.

[0096] 2. By extending obliquely toward the bottom surface of the base 1, the clip 115 can be clamped on the bottom surface of the substrate 3, further increasing the positioning effect between the base 1 and the substrate 3; and a gap B can be formed between the bottom surface of the substrate 3 and the connection between the clip 115 and the support 111. When the buckling mechanism A is disassembled, the gap B provides space for the clip 115 to bend and move, preventing the clip 115 from breaking.

[0097] 3. The guided part 21 (convex shaft) can be an integrally formed structure with the clamping member 2, thereby reducing the number of related components of the clamping member 2 and thus reducing production costs.

[0098] In summary, the reusable quick-release buckle mechanism of the present invention can indeed achieve the effects of quick and convenient loading and unloading, stable positioning, and easy observation and confirmation of the assembly status. It is a novel and progressive invention, and therefore an application for invention patent is filed in accordance with the law. However, the above description is only a description of the preferred embodiment of the present invention. All variations, modifications, alterations, or equivalent substitutions extended from the technical means and scope of the present invention should also fall within the scope of the patent application of the present invention.
