Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a fixing frame assembly. Background Art

[0002] How to ensure that components in electronic components are stably fixed has always been a problem that needs to be solved in the field of electronic technology. For example, when a user wants to fix an adapter card in a chassis, an adapter card cage may be used, such as a support frame and one or more stopper structures. The stopper structure is used to ensure that the electronic component will not jump due to impact or shaking.

[0003] However, due to the narrow space in the chassis, the design of the stopper structure in the fixed structure is limited. In addition to the size of the stopper structure needing to be reduced as much as possible, some designs that take up a large space (such as a sliding stopper structure) are also less popular with users.

[0004] Therefore, how to come up with a fixing frame assembly that takes up little space and is strong and durable is one of the problems that the industry is eager to invest research and development resources to solve. Summary of the invention

[0005] Based on this, it is necessary to provide a fixing frame assembly that occupies a small space and is strong and durable to address the above problems.

[0006] A fixing frame assembly includes a supporting frame and a limiting member. The supporting frame includes a first plate body and a limiting protrusion. The limiting protrusion is convexly arranged on the first plate body. The limiting member is pivotally connected to the first plate body. The limiting member has a closed position and an open position relative to the first plate body, and the limiting member includes an arc-shaped groove. The arc-shaped groove includes a first receiving groove, a raised area and a second receiving groove. The limiting protrusion is movably arranged in the arc-shaped groove, and when the limiting member is in the closed position relative to the first plate body, the limiting protrusion is located in the first receiving groove. During the period when the limiting member rotates from the closed position to the open position relative to the first plate body, the limiting protrusion slides along the arc-shaped groove and is interference fit with the raised area. When the limiting member is in the open position relative to the first plate body, the limiting protrusion is located in the second receiving groove.

[0007] The technical solution is further described below:

[0008] In one embodiment, the limiting member is configured to be rotatable relative to the first plate body around an axis, and the arc-shaped groove is configured to extend around the axis.

[0009] In one embodiment, the support frame further includes a second plate body. The first plate body includes a first recess. The second plate body includes a second recess arranged along the axis opposite to the first recess. The stopper includes two protrusions, which are respectively arranged in the first recess and the second recess.

[0010] In one embodiment, the raised area includes a first guide surface and a plane. Two sides of the first guide surface are respectively connected to the groove wall and the plane of the first accommodating groove.

[0011] In one embodiment, the raised area includes a second guide surface and a plane. Two sides of the second guide surface are respectively connected to the groove wall and the plane of the second accommodating groove.

[0012] In one embodiment, at least one of the first receiving groove and the second receiving groove includes a bottom surface and a side wall surface surrounding the bottom surface.

[0013] In one embodiment, the limiting member includes a first surface. The first plate includes a second surface. The first surface and the second surface are arranged opposite to each other in an axial direction. The arc groove is arranged on the first surface. The limiting protrusion is arranged on the second surface.

[0014] In one embodiment, there is a first distance between the first surface and the second surface in the axial direction. The raised area includes a first guide surface and a plane, and the two sides of the first guide surface are respectively connected to the groove wall and the plane of the first accommodating groove. There is a second distance between the end of the groove wall of the first accommodating groove away from the groove bottom and the plane in the axial direction. The second distance is equal to the first distance.

[0015] In one embodiment, the first receiving groove includes a bottom surface and a side wall surrounding the bottom surface, and a third distance is axially provided between the bottom surface and an end of the side wall connected to the first guide surface, and the third distance is greater than the first distance.

[0016] In one embodiment, the first receiving groove and the second receiving groove are respectively located at two ends of the arc groove. The raised area includes a first guide surface, a plane and a second guide surface. Both sides of the plane are connected to the first guide surface and the second guide surface respectively. The first guide surface is connected to the groove wall of the first receiving groove. The second guide surface is connected to the groove wall of the second receiving groove.

[0017] In the technical solution of the present application, the position-limiting protrusion in the present application can selectively engage with the first receiving groove and the second receiving groove by interference fit with the raised area, thereby providing a stable stop and position-limiting function for the fixing frame assembly. Compared with the prior art, the arc-shaped groove including the first receiving groove, the second receiving groove and the raised area can better guide the sliding of the position-limiting protrusion, making the position-limiting component more durable in addition to being easier to use and not occupying extra space.

[0036] Please refer to Figure 1 . Figure 1 Schematic diagram of the three-dimensional structure of a fixing frame assembly 10 of an embodiment of the present application. In this embodiment, the fixing frame assembly 10 includes a supporting frame 100 and a limiting member 200. The supporting frame 100 includes a first plate body 110, a second plate body 120 and a third plate body 130. The first plate body 110 and the second plate body 120 are arranged opposite to each other in the axial direction x. The third plate body 130 connects the first plate body 110 and the second plate body 120. The limiting member 200 is rotatably pivoted to the first plate body 110 and the second plate body 120. In other words, the limiting member 200 is rotatably pivoted between the first plate body 110 and the second plate body 120. The limiting member 200 is configured to be able to rotate relative to the supporting frame 100 around an axis A. The axis A extends along the axial direction x. The first plate body 110, the second plate body 120, the third plate body 130 and the limiting member 200 surround and form an accommodating space OP. One or more electronic components (not shown) may be disposed in the accommodation space OP. The one or more electronic components may abut against the third plate 130 along the axial direction z.

[0037] In some embodiments, the support frame 100 can be made of a metal material, such as iron, stainless steel, or any metal material with suitable hardness. The stopper 200 can be made of a plastic material. In some preferred embodiments, the stopper 200 can be made of an elastic plastic material.

[0038] In some embodiments, the electronic component may include an adapter card, an expansion card, a solid state drive, or other suitable electronic components. The electronic component may also include an adapter card and one or more brackets for fixing the adapter card.

[0039] Please refer to Figure 2 . Figure 2 FIG. 1 is a perspective view of a fixing frame assembly 10 according to an embodiment of the present application. In order to clearly describe the structure of the fixing frame assembly 10, Figure 2 The position-limiting member 200 is transparent, the outline is indicated by a dotted line, and some details are omitted. In this embodiment, the first plate 110 includes a first recess 101. The second plate 120 includes a second recess 102. The first recess 101 is arranged opposite to the second recess 102 along the axis A. The position-limiting member 200 includes two protrusions 202, and the two protrusions 202 are respectively arranged in the first recess 101 and the second recess 102. Accordingly, the position-limiting member 200 can rotate around the axis A relative to the first plate 110.

[0040] It should be noted that in the embodiment of the present application, the first recess 101 and the second recess 102 may be through-holes penetrating the plate body, or grooves not penetrating the plate body. The present application does not intend to limit whether the first recess 101 and the second recess 102 penetrate the plate body.

[0041] Please refer to Figure 1 and Figure 2 In some embodiments, the stopper 200 can rotate relative to the support frame 100 to be in a closed position (eg Figure 1 ) or the open position (as shown Figure 2 When the stopper 200 is in the closed position, the stopper 200 is configured to limit the electronic component (not shown) in the axial direction y, and the electronic component can be stably arranged in the accommodation space OP. In other words, when the stopper 200 is in the open position, the electronic component can enter or leave the accommodation space OP along the axial direction y.

[0042] Please refer to Figure 2 and Figure 3 . Figure 3 1 is a bottom view of a stopper 200 of an embodiment of the present application. In some embodiments, the support frame 100 further includes a stopper protrusion 140. The stopper protrusion 140 is formed by the first plate 110 protruding along the axial direction x. The stopper 200 includes an arc groove 210, and the stopper protrusion 140 is movably disposed in the arc groove. When the stopper 200 rotates relative to the support frame 100 along the axis A, the stopper protrusion 140 slides along the arc groove 210.

[0043] Please continue to refer to Figure 3. In this embodiment, the limit member 200 includes a first surface 204 and a protrusion 202. The protrusion 202 protrudes relative to the first surface 204 in the axial direction x. An arc-shaped groove 210 is formed on the limit frame 200, and the arc-shaped groove 210 is formed on the first surface 204. The arc-shaped groove 210 is recessed relative to the first surface 204 in the axial direction x. The arc-shaped groove 210 includes a first accommodating groove 211 and a second accommodating groove 215, and the first accommodating groove 211 and the second accommodating groove 215 are located at both ends of the arc-shaped groove 210. The arc-shaped groove 210 also includes a first guide surface 212, a plane 213 and a second guide surface 214. The first guide surface 212 is an inclined surface connecting the groove wall of the first accommodating groove 211 and the plane 213. In other words, the two sides of the first guide surface 212 are respectively connected to the groove wall of the first accommodating groove 211 and the plane 213. The second guide surface 214 is an inclined surface connecting the groove wall of the second receiving groove 215 and the plane 213. In other words, the two sides of the second guide surface 214 are respectively connected to the plane 213 and the groove wall of the second receiving groove 215. The first guide surface 212, the plane 213 and the second guide surface 214 can be collectively referred to as a raised area. More precisely, in the axial direction x, with the first surface 204 as a reference, the first receiving groove 211 and the second receiving groove 215 have a deeper depression than the raised area. In the axial direction x, the plane 213 is generally closer to the first surface 204 than the first guide surface 212 and the second guide surface 214.

[0044] Please refer to Figure 4 . Figure 4 for Figure 1 1 is a partial three-dimensional perspective view of the fixing frame assembly 10 in FIG. In the present embodiment, the limiting protrusion 140 is formed on the second surface 104 of the first plate body 110. In more detail, the limiting protrusion 140 is formed by the second surface 104 protruding toward the limiting member 200 along the axial direction x. When the limiting member 200 is in the closed position relative to the first plate body 110, the limiting protrusion 140 is located in the first receiving groove 211. Since the limiting protrusion 140 is engaged in the first receiving groove 211, the limiting member 200 cannot be rotated relative to the supporting frame 100 at will, thereby achieving the effect of fixing the limiting member 200. Accordingly, the limiting protrusion 140 engaged in the first receiving groove 211 can provide a beneficial effect of reducing the wear and deformation of the limiting member 200.

[0045] Please continue to refer to Figure 4 In some embodiments, the first receiving groove 211 includes a bottom surface 211a and a side wall surface 211b. The side wall surface 211b surrounds the bottom surface 211a. The two sides of the first guide surface 212 are respectively connected to the side wall surface 211b and the plane 213. The second receiving groove 215 includes a bottom surface 215a and a side wall surface 215b. The side wall surface 215b surrounds the bottom surface 215a. The two sides of the second guide surface 214 are respectively connected to the plane 213 and the side wall surface 215b.

[0046] Please also refer to Figure 3 and Figure 4 In some embodiments, the arc groove 210 extends around the axis A. In other words, the arc groove 210 extends around the protrusion 202. In more detail, the arc groove 210 extends around the protrusion 202 with the center point of the protrusion 202 as the center of the circle. Accordingly, when the limiting member 200 rotates around the axis A relative to the supporting frame 100, the limiting protrusion 140 can slide along the arc groove 210 with the axis A as the center of the circle.

[0047] In some alternative embodiments, the first receiving groove 211 and the second receiving groove 215 are through holes penetrating the first surface 204 .

[0048] Please also refer to Figure 4 and Figure 5 . Figure 5 for Figure 2 1. A partial perspective view of the fixing frame assembly 10 in FIG. 1. In this embodiment, the stopper 200 rotates relative to the first plate 110 along the axis A. When the stopper 200 is moved from the closed position (eg Figure 4 ) is rotated relative to the first plate 110 to an open position (as shown Figure 5 During the process (as shown in FIG. 2 ), the limiting protrusion 140 slides along the arc groove 210. First, the limiting protrusion 140 is separated from the first receiving groove 211. Then, the limiting protrusion 140 and the raised area (the first guide surface 212, the plane 213 and the second guide surface 214) slide relative to each other in an interference fit manner. Then, the limiting protrusion 140 enters the second receiving groove 215. Figure 5 As shown, since the limiting protrusion 140 is engaged in the second receiving groove 215, the limiting member 200 is fixed in the open position and cannot rotate freely relative to the supporting frame 100. Accordingly, by the action between the limiting protrusion 140 and the arc groove 210, the limiting member 200 can be selectively fixed in the closed position or the open position.

[0049] The following will describe in detail the movement of the stopper 200 from the closed position (eg Figure 4 ) is rotated relative to the first plate 110 to an open position (as shown Figure 5 During the process shown in FIG. 1 , the limiting protrusion 140 slides over the raised area in an interference fit manner. Please continue to refer to Figure 4 and Figure 5. In the present embodiment, first, the limiting protrusion 140 abuts against the side wall surface 211b. Then, the limiting protrusion 140 is forced to slide over the side wall surface 211b in an interference fit manner and contact the first guide surface 212. Then, after the limiting protrusion 140 slides over the side wall surface 211b in an interference fit manner, the limiting protrusion 140 slides onto the plane 213 under the guidance of the first guide surface 212. In the axial direction x, since the distance between the plane 213 and the second surface 104 is shorter than the distance between the first guide surface 212 and the second surface 104, a greater force is required to overcome the resistance between the limiting protrusion 140 and the plane 213. Then, after sliding over the plane 213 in an interference fit manner, the limiting protrusion 140 slides into the second accommodating groove 215 under the guidance of the second guide surface 214. In summary, the raised area can increase the resistance of the limiting protrusion 140 sliding between the first receiving groove 211 and the second receiving groove 215, so that the limiting member 200 will not be opened due to shaking or vibration, causing the electronic component to fall and be damaged.

[0050] In some embodiments, it is worth mentioning that, during the process of the stopper 200 rotating from the closed position to the open position relative to the first plate 110, the resistance between the arc groove 210 and the stopper protrusion 140 first increases gradually and then decreases gradually. In more detail, during the period when the stopper protrusion 140 slides from the first receiving groove 211 to the plane 213, the resistance between the arc groove 210 and the stopper protrusion 140 gradually increases with the slope of the first guide surface 212, and has the largest resistance at the plane 213. During the period when the stopper protrusion 140 slides from the plane 213 to the second receiving groove 215, the resistance between the arc groove 210 and the stopper protrusion 140 gradually decreases with the slope of the second guide surface 214.

[0051] The following will describe in detail the movement of the stopper 200 from the open position (eg Figure 5 ) is rotated relative to the first plate 110 to a closed position (as shown Figure 4 During the process shown in FIG. 1 , the limiting protrusion 140 slides over the raised area in an interference fit manner. Please continue to refer to Figure 4 and Figure 5. In the present embodiment, first, the limiting protrusion 140 abuts against the side wall surface 215b. Then, the limiting protrusion 140 is forced to slide over the side wall surface 215b in an interference fit manner and contacts the second guide surface 214. Then, after the limiting protrusion 140 slides over the side wall surface 215b in an interference fit manner, the limiting protrusion 140 slides onto the plane 213 under the guidance of the second guide surface 214. Then, the limiting protrusion 140 is forced to slide over the plane 213 in an interference fit manner. Then, the limiting protrusion 140 slides into the first accommodating groove 211 under the guidance of the first guide surface 212, so that the limiting member 200 is fixed in the closed position. As can be seen from the above description, the first guide surface 212 and the second guide surface 214 can make the limiting protrusion 140 slide more smoothly in the arc groove 210.

[0052] In some embodiments, it is worth mentioning that, during the process of the stopper 200 rotating from the open position to the closed position relative to the first plate 110, the resistance between the arc groove 210 and the stopper protrusion 140 first increases gradually and then decreases gradually. In more detail, during the period when the stopper protrusion 140 slides from the second receiving groove 215 to the plane 213, the resistance between the arc groove 210 and the stopper protrusion 140 gradually increases with the slope of the second guide surface 214, and has the maximum resistance at the plane 213. During the period when the stopper protrusion 140 slides from the plane 213 to the first receiving groove 211, the resistance between the arc groove 210 and the stopper protrusion 140 gradually decreases with the slope of the first guide surface 212.

[0053] It should be noted that, in some alternative embodiments, the raised area may not include the first guide surface 212 and the second guide surface 214. The two sides of the plane 213 are respectively connected to the groove wall of the first accommodating groove 211 and the groove wall of the second accommodating groove 215. Since the raised area does not include the guide surface, the raised area can provide greater resistance to make the limiter 200 less likely to rotate. In other alternative embodiments, the raised area may not include the first guide surface 212. Since the raised area includes the second guide surface 214 but not the first guide surface 212, the limiter 200 can be easily rotated from the open position back to the closed position, but it is not easy to rotate from the closed position to the open position. The effect of preventing the limiter 200 from opening and falling due to impact or shaking can be achieved.

[0054] Please also refer to Figure 6 and Figure 7 . Figure 6 It is a bottom view of the fixing frame assembly 10 according to one embodiment of the present application. Figure 7 for Figure 6Schematic diagram of the cross-sectional structure of the fixing frame assembly 10 observed along the cutting line 7-7. In this embodiment, the first surface 204 and the second surface 104 are opposite to each other in the axial direction x. There is a first distance D1 between the first surface 204 and the second surface 104 in the axial direction x. The first distance D1 can be defined as the maximum distance that can be between the first surface 204 and the second surface 104. There is a second distance D2 between the plane 213 and the end of the groove wall of the first receiving groove 211 away from the groove bottom in the axial direction x. In more detail, there is a second distance D2 between the plane 213 and the end of the side wall surface 211b of the first receiving groove 211 away from the bottom surface 211a in the axial direction x. The second distance D2 is equal to the first distance D1. In some embodiments, the second distance D2 can also be defined as the distance between the highest point of the first guide surface 212 in the axial direction x (where the plane 213 is connected) and the lowest point of the first guide surface 212 in the axial direction x (where the side wall surface 211b of the first receiving groove 211 is connected) in the axial direction x. Since the second distance D2 is equal to the first distance D1, the limiting protrusion 140 can closely match the arc groove 210 during the interference operation of the limiting member 200 and the first plate 110. The tightly matched limiting protrusion 140 and the arc groove 210 can make the limiting member 200 easy to slide and not easy to bounce off due to impact and cause the piece to fall off. In some alternative embodiments, since a greater resistance is needed to prevent the limiting member 200 from leaving the closed position, the second distance D2 can be smaller than the first distance D1.

[0055] Please continue to refer to Figure 6 and Figure 7 In some embodiments, a third distance D3 is provided between one end of the first guide surface 212 connected to the side wall surface 211b and the bottom surface 211a of the first receiving groove 211 in the axial direction x. The third distance D3 can be defined as the shortest distance between the first guide surface 212 and the bottom surface 211a. The third distance D3 is greater than the first distance D1. Since the third distance D3 is greater than the first distance D1, the limiting protrusion 140 can be buffered in the first receiving groove 211 without resistance, and plastic deformation of the limiting member 200 caused by long-term compression can be avoided.

[0056] Please refer to Figure 8 . Figure 8 for Figure 6Schematic diagram of the cross-sectional structure of the fixing frame assembly 10 observed along the cutting line 8-8 in the embodiment. In the present embodiment, similarly, there is a first distance D1 between the first surface 204 and the second surface 104 in the axial direction x. There is a fourth distance D4 between the end of the groove wall of the second receiving groove 215 away from the groove bottom and the plane 213 in the axial direction x. In more detail, there is a fourth distance D4 between the plane 213 and the end of the side wall surface 215b of the second receiving groove 215 away from the bottom surface 215a in the axial direction x. The fourth distance D4 is equal to the first distance D1. In some embodiments, the fourth distance D4 can also be defined as the distance in the axial direction x between the highest point of the second guide surface 214 in the axial direction x (where the plane 213 is connected) and the lowest point of the second guide surface 214 in the axial direction x (where the side wall surface 215b of the second receiving groove 215 is connected). Since the fourth distance D4 is equal to the first distance D1 , during the interference operation between the limiting member 200 and the first plate 110 , the limiting protrusion 140 can be tightly matched with the arc groove 210 .

[0057] Please continue to refer to Figure 8 In some embodiments, a fifth distance D5 is provided between one end of the second guide surface 214 connected to the side wall surface 211b and the bottom surface 215a of the second receiving groove 215. The fifth distance D5 can be defined as the shortest distance between the second guide surface 214 and the bottom surface 215a. The fifth distance D5 is greater than the first distance D1. Since the fifth distance D5 is greater than the first distance D1, the limiting protrusion 140 can be buffered in the second receiving groove 215 without resistance, and the plastic deformation of the limiting member 200 caused by long-term compression can be avoided.

[0058] In one embodiment of the present application, the fixing frame assembly 10 of the present application can be set in a server. The server can be used for artificial intelligence (AI) computing, edge computing, and can also be used as a 5G server, a cloud server, or an Internet of Vehicles server.

[0059] In summary, in the fixing frame assembly 10 of the present application, the limiting member 200 can be smoothly rotated between the open position and the closed position through the guidance of the limiting protrusion 140 and the arc groove 210, and it is not easy to cause wear or breakage of the limiting member 200 due to multiple rotations or improper force.
