DETAILED DESCRIPTION
[0028] 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.
[0029] With the widespread application of electronic devices, electronic devices of different models and sizes have been derived, and the models and applications of the components therein are diverse. Taking the components as solid-state memory cards as an example, the solid-state memory cards currently used mainly include long cards of model 2280 and short cards of model 2242. The two types of solid-state memory cards require different fixing structures and cannot be directly replaced and interchanged. In order to adapt the two types of solid-state memory cards in the same electronic device at the same time, a limit module of the embodiment of the present disclosure is proposed. Among them, the electronic device may include a desktop computer, a laptop computer, a tablet or a mobile phone terminal, etc.
[0030] For ease of explanation, the embodiment of the present disclosure takes the electronic device as a laptop computer as an example to illustrate the present solution.
[0031] Exemplarily, a laptop computer generally includes: an external structure and an internal structure. The external structure generally includes a housing, a display screen, a keyboard, a touchpad, a power switch and an interface. The internal structure generally includes a motherboard, a processor, a memory, a hard disk, a graphics card, a sound card, a network card, etc. Among them, the housing generally includes an upper shell and a lower shell. The upper shell includes a top shell structure that fits with the display, and the lower shell includes an upper shell structure and a lower shell structure that are installed with the keyboard. The limit module involved in the embodiments of the present disclosure is generally installed in the lower shell. Furthermore, the limit module can be fixed in any space between the upper shell structure and the lower shell structure.
[0032] refer to Figure 1-Figure 8 The embodiment of the present disclosure provides a limiting module 001, including: an upper sliding bracket 10, a lower sliding bracket 20 and a supporting bracket 30, and the supporting bracket 30 can slide, rotate and move between the upper sliding bracket 10 and the lower sliding bracket 20.
[0033] The support bracket 30 and the upper sliding bracket 10 are slidably connected by the limiting shaft 40. Specifically, the upper sliding bracket 10 has a first path 101, and the first path 101 is configured as a closed structure extending along a first direction. The first direction can be understood as any one of the length direction or width direction of the upper sliding bracket 10 itself, and the closed structure can be understood as a slideway with a closed path; wherein the first path 101 includes a first limiting end 1011 and a second limiting end 1012 away from the first limiting end 1011; the limiting shaft 40 is slidably matched with the slideway where the first path 101 is located, and can slide and move along the first path 101.
[0034] In addition, the support bracket 30 and the lower sliding bracket 20 are rotated and moved through the first positioning member 50. Specifically, the lower sliding bracket 20 has a sliding path 201, which is a slideway adapted to the aforementioned first path 101 and located below the first path 101, so that the support bracket 30 can follow the limiting shaft 40 to slide and move on the first path 101. At the same time, the support bracket 30 can also rotate relative to the lower sliding bracket 20 at the position of the first positioning member 50, and the support bracket 30 can also follow the first positioning member 50 to slide and move along the sliding path 201.
[0035] In this way, the support bracket 30 is clamped between the upper sliding bracket 10 and the lower sliding bracket 20, and rotates between the two and moves along the first path 101, which can facilitate the support bracket 30 to move to the first limit end 1011 and the second limit end 1012 of the first path 101, thereby positioning the support bracket 30 at different positions of the lower sliding bracket 20, and then used to limit and fix solid-state memory cards 60 of different models and sizes.
[0036] Considering the fixing effect of the support bracket 30 on the solid-state memory card 60, the support bracket 30 has a raised outer profile for engaging with the solid-state memory card 60. It should be pointed out here that the solid-state memory card 60 has a recessed portion for fixing and limiting, and the raised outer profile of the support bracket 30 can be engaged and fixed with the recessed portion, which is convenient for assembly and disassembly.
[0037] Using the above-mentioned limit module 001, the first positioning member 50 is rotatably connected to the support bracket 30, and passes through the support bracket 30 to slide or clearance fit with the sliding path 201; the limit shaft 40 passes through the upper sliding bracket 10 and is rotatably connected to the support bracket 30, the limit shaft 40 slides or clearance fits with the first path 101, and the limit shaft 40 is configured to provide power for rotational movement to the support bracket 30, and the power for rotational movement here can be applied manually or by automated equipment.
[0038] Considering that the limiting shaft 40 can achieve stable limiting and fixing of the solid-state memory card 60 at the first limiting end 1011 or the second limiting end 1012 , a solution is adopted in which the limiting shaft 40 can be respectively engaged with the first limiting end 1011 and the second limiting end 1012 . Specifically, the first path 101 leaves a slide area 1013 between the first limit end 1011 and the second limit end 1012, and the space at the connection position between the first limit end 1011 and the second limit end 1012 and the slide area 1013 becomes smaller. Specifically, a small protrusion 1014 is set at the connection position, which at least partially interferes with the limit shaft 40 along its own radial direction. In this way, when the limit shaft 40 moves to the position of the small protrusion 1014, due to the reduction of the space of the slide, the limit shaft 40 needs to overcome the extrusion friction between the two before moving to the first limit end 1011 or the second limit end 1012, and under the setting of the small protrusion 1014, the limit shaft 40 can be engaged with the first limit end 1011 or the second limit end 1012 without the action of external force, so as to achieve fixation at the two end points.
[0039] Considering that the limiting shaft 40 can smoothly move past the position of the small protrusion 1014, the upper sliding bracket 10 further includes a deformable hole 102, which is arranged outside the first limiting end 1011 and / or the second limiting end 1012, so that when a mutual extrusion force is generated between the limiting shaft 40 and the small protrusion 1014, the extrusion force can be released in the space of the deformable hole 102. Specifically, the deformable hole 102 is a through hole along the thickness direction of the upper sliding bracket 10, and any inner wall of the through hole can be deformed toward the inside thereof. By setting the deformable hole 102, the extrusion force that the limiting shaft 40 needs to resist can be reduced.
[0040] Considering that the limiting shaft 40 is convenient for applying the power of the rotational movement, the limiting shaft 40 includes an upper cap body 41 and a lower shaft body 42. The radial dimension of the upper cap body 41 is larger than the radial dimension of the lower shaft body 42. The vertical projection area of the upper cap body 41 falling on the upper sliding bracket 10 at least covers the first limiting end 1011 or the second limiting end 1012. Taking the manual application of the power of the rotational movement as an example, the movement of the limiting shaft 40 can be achieved by manually moving the upper cap body 41.
[0041] Considering the non-slip sliding movement of the limit shaft 40 along the sliding path 201 in the lower sliding bracket 20 , the limit shaft 40 also includes a limit spring piece 43 , which is sleeved on the bottom of the lower shaft body 42 , and the limit shaft 40 slides with the sliding path 201 through the limit spring piece 43 .
[0042] Considering the coordinated application of the first path 101 and the sliding path 201, the first path 101 is constructed as a straight path; the sliding path 201 is constructed as a bending path; when the first positioning member 50 moves along the sliding path 201, the limiting axis 40 moves along the first path 101, and can move the support bracket 30 between the first limiting end 1011 and the second limiting end 1012 under the adaptation setting of the two paths.
[0043] Further considering the assembly environment between the upper sliding bracket 10 and the lower sliding bracket 20, the upper sliding bracket 10 is constructed as a stepped surface structure as a whole, including a first plate 11 and a second plate 12 located above the first plate 11, wherein the upper sliding bracket 10 is detachably connected to the lower sliding bracket 20 through the first plate 11. Exemplarily, the first plate 11 has a mounting hole, and the lower sliding bracket 20 correspondingly has a positioning portion 203, and the positioning portion 203 is constructed to have a card edge that elastically shrinks toward its own center, and each card edge is arranged around a circle. In a static state, each card edge is interfered with the inner wall of the mounting hole. During installation, each card edge is manually retracted inward to extend into the mounting hole. Each card edge abuts against the inner wall of the mounting hole in a static state, thereby realizing a detachable snap-fit installation between the upper sliding bracket 10 and the lower sliding bracket 20. In addition, the first path 101, the first limit end 1011, the second limit end 1012 and the deformable hole 102 are all formed on the second plate 12; the lower sliding bracket 20 also includes a support rib 202, which is arranged on the lower sliding bracket 20 for installing one side of the upper sliding bracket 10, and the support rib 202 is supported on the bottom surface of the second plate 12.
[0044] Exemplarily, the support rib 202 can be arranged along the outer periphery of the sliding path 201 to provide a slideway for the limiting spring piece 43; or, the support rib 202 can be arranged along the inner edge of the second plate 12 to prevent dust from entering through the gap between the second plate 12 and the lower sliding bracket 20. At the same time, the setting of the support rib 202 can avoid direct sliding friction between the support bracket 30 and the lower sliding.
[0045] Considering that the support bracket 30 can rotate and move between the upper sliding bracket 10 and the lower sliding bracket 20 and can fix the solid-state memory card 60 at the same time, the support bracket 30 includes a plane portion 31 and a protruding portion 32, wherein the plane portion 31 has a first hole 33 and a second hole 34 separately arranged, the first hole 33 is rotatably connected to the lower shaft body 42 of the limiting shaft 40, and the second hole 34 is rotatably connected to the first positioning member 50, so that the first positioning member 50 and the limiting shaft 40 can be respectively rotatably connected to the support bracket 30 on the plane portion 31; in addition, considering that the support bracket 30 will not interfere with the upper sliding bracket 10 during rotation, there is a space for the plane portion 31 to rotate between the second plate 12 and the lower sliding bracket 20; the protruding outer profile is formed on the protruding portion 32, specifically, the top surface of the protruding portion 32 has a clamping portion 321, and the clamping portion 321 is used to be clamped and fixed with the recessed portion of the solid-state memory card 60.
[0046] By adopting the limit module 001 of the embodiment of the present disclosure, the support bracket 30 slides, rotates and moves between the upper sliding bracket 10 and the lower sliding bracket 20, wherein the sliding, rotating and moving of the support bracket 30 relative to the upper sliding bracket 10 is realized by the sliding cooperation between the limit shaft 40 and the first path 101, and the first path 101 includes a first limit end 1011 and a second limit end 1012, so that the limit shaft 40 can be moved from the first limit end 1011 to the second limit end 1012, so as to drive the support bracket 30 to move from the first limit end 1011 to the second limit end 1012; in addition, the sliding, rotating and moving of the support bracket 30 relative to the lower sliding bracket 20 is realized by the sliding cooperation between the first positioning member 50 and the sliding path 201, so as to further adapt to solid-state storage cards 60 of different models and sizes, and limit and fix them.
[0047] The disclosed embodiment also provides an electronic device, including the above-mentioned limit module 001, which is used to adapt to the positioning and locking of different types of solid-state memory cards 60, and can adapt to the storage memory requirements of different types of electronic devices. At the same time, the limit module 001 can be assembled in any type of electronic device, so that different types of solid-state memory cards 60 can be assembled and fixed in the same limit module 001.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.
