Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronics, and in particular, to a fixing frame assembly. BACKGROUND

[0002] How to ensure that components in an electronic assembly are stably fixed has always been a problem to be solved in the field of electronics. For example, when a user wants to fix an adapter card in a case, the user may use an adapter card cage, such as a support frame and one or more stop structure members, for fixing. The stop structure member is used to ensure that the electronic assembly does not jump due to impact or shaking.

[0003] However, due to the narrow space in the case, the design of the stop structure member in the fixing structure is limited. In addition to the size of the stop structure member needing to be as small as possible, some designs that occupy a large space, such as sliding stop structure members, are less favored by users.

[0004] Therefore, how to propose a fixing frame assembly that occupies a small space and is firm and durable is one of the problems that the industry urgently needs to invest in research and development resources to solve. SUMMARY

[0005] Therefore, it is necessary to provide a fixing frame assembly that occupies a small space and is firm and durable in view of the above problems.

[0006] A fixing frame assembly includes a support frame and a limiting member. The support frame includes a first plate body and a limiting protrusion. The limiting protrusion is protruded from 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 accommodating groove, a protruding region, and a second accommodating groove. The limiting protrusion is movably arranged in the arc-shaped groove. When the limiting member is located at the closed position relative to the first plate body, the limiting protrusion is located in the first accommodating groove. During the limiting member is rotated 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 in interference fit with the protruding region. When the limiting member is located at the open position relative to the first plate body, the limiting protrusion is located in the second accommodating groove.

[0007] The technical solutions are further described below:

[0008] In one of the embodiments, the limiting member is configured to rotate relative to the first plate body about an axis. The arc-shaped groove is configured to extend around the axis.

[0009] In one of the embodiments, 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 opposite to the first recess along the axis. The limiting member includes two protrusions arranged in the first recess and the second recess, respectively.

[0010] In one embodiment, the protruding region comprises a first guide surface and a flat surface. Two sides of the first guide surface are connected to a groove wall of the first receiving groove and the flat surface, respectively.

[0011] In one embodiment, the protruding region comprises a second guide surface and a flat surface. Two sides of the second guide surface are connected to a groove wall of the second receiving groove and the flat surface, respectively.

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

[0013] In one embodiment, the limiting member comprises a first surface. The first plate body comprises a second surface. The first surface and the second surface are oppositely arranged in an axial direction. The arc-shaped groove is arranged on the first surface. The limiting protrusion is arranged on the second surface.

[0014] In one embodiment, the first surface and the second surface have a first distance in the axial direction. The protruding region comprises a first guide surface and a flat surface. Two sides of the first guide surface are connected to a groove wall of the first receiving groove and the flat surface, respectively. An end of the groove wall of the first receiving groove, which is away from the groove bottom, has a second distance with the flat surface in the axial direction. The second distance is equal to the first distance.

[0015] In one embodiment, the first receiving groove comprises a bottom surface and a sidewall surface surrounding the bottom surface. A third distance is between the bottom surface and an end of the sidewall surface, which is connected to the first guide surface, in the axial direction. 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-shaped groove. The protruding region comprises a first guide surface, a flat surface and a second guide surface. Two sides of the flat surface are connected to the first guide surface and the second guide surface, respectively. The first guide surface is connected to a groove wall of the first receiving groove. The second guide surface is connected to a groove wall of the second receiving groove.

[0017] In the technical solution of the present application, the limiting protrusion can be selectively clamped into the first receiving groove and the second receiving groove through interference fit with the protruding region, thereby providing stable stop and limiting functions for the fixing frame assembly. Compared with the prior art, the arc-shaped groove comprising the first receiving groove, the second receiving groove and the protruding region can better guide the sliding of the limiting protrusion, so that the limiting member is more durable in addition to being easier to use and not occupying additional space.

The support 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 oppositely arranged along an 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 pivotally connected to the first plate body 110 and the second plate body 120. In other words, the limiting member 200 is pivotally connected between the first plate body 110 and the second plate body 120. The limiting member 200 is configured to rotate relative to the support frame 100 about an axis A. The axis A extends along the axial direction x.

[0039] Please refer to Figure 2 . Figure 2 is a perspective view of a bracket assembly 10 according to an embodiment of the present application. In order to clearly describe the structure of the bracket assembly 10, Figure 2 is a perspective view of the bracket assembly 10 according to an embodiment of the present application. In order to clearly describe the structure of the bracket assembly 10,

[0040] It should be noted that in the embodiments of the present application, the first recess 101 and the second recess 102 can be perforations that penetrate the plate body, or can be recesses that do not penetrate 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 limiting member 200 can be rotated relative to the support frame 100 to be located in a closed position (as shown in Figure 1 ) or an open position (as shown in Figure 2 ). When the limiting member 200 is located in the closed position, the limiting member 200 is configured to limit the electronic component (not shown in the figure) in the axial direction y, and the electronic component can be stably arranged in the accommodation space OP. In other words, when the limiting member 200 is located 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 is a bottom view of the limiting member 200 according to an embodiment of the present application. In some embodiments, the support frame 100 further includes a limiting protrusion 140. The limiting protrusion 140 is formed by the first plate body 110 protruding along the axial direction x. The limiting member 200 includes an arc-shaped groove 210, and the limiting protrusion 140 is movably arranged in the arc-shaped groove. When the limiting member 200 is rotated relative to the support frame 100 along the axial direction A, the limiting protrusion 140 slides along the arc-shaped groove 210.

[0043] Please refer to Figure 3In the present embodiment, the stopper 200 includes a first surface 204 and a protrusion 202. The protrusion 202 protrudes in the axial direction x relative to the first surface 204. The stopper 200 has an arc-shaped groove 210 formed on the first surface 204. The arc-shaped groove 210 is recessed in the axial direction x relative to the first surface 204. The arc-shaped groove 210 includes a first receiving groove 211 and a second receiving groove 215, which are located at two ends of the arc-shaped groove 210. The arc-shaped groove 210 further includes a first guide surface 212, a flat surface 213, and a second guide surface 214. The first guide surface 212 is a slanted surface connecting a groove wall of the first receiving groove 211 and the flat surface 213. In other words, the two sides of the first guide surface 212 are connected to the groove wall of the first receiving groove 211 and the flat surface 213, respectively. The second guide surface 214 is a slanted surface connecting a groove wall of the second receiving groove 215 and the flat surface 213. In other words, the two sides of the second guide surface 214 are connected to the flat surface 213 and the groove wall of the second receiving groove 215, respectively. The first guide surface 212, the flat surface 213, and the second guide surface 214 can be collectively referred to as a protruding region. More specifically, in the axial direction x, the first receiving groove 211 and the second receiving groove 215 are recessed deeper than the protruding region relative to the first surface 204. In the axial direction x, the flat surface 213 is 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 a partial perspective view of the fixing frame assembly 10 in In the present embodiment, the stopper 200 includes a first surface 204 and a protrusion 202. The protrusion 202 protrudes in the axial direction x relative to the first surface 204. The stopper 200 has an arc-shaped groove 210 formed on the first surface 204. The arc-shaped groove 210 is recessed in the axial direction x relative to the first surface 204. The arc-shaped groove 210 includes a first receiving groove 211 and a second receiving groove 215, which are located at two ends of the arc-shaped groove 210. The arc-shaped groove 210 further includes a first guide surface 212, a flat surface 213, and a second guide surface 214. The first guide surface 212 is a slanted surface connecting a groove wall of the first receiving groove 211 and the flat surface 213. In other words, the two sides of the first guide surface 212 are connected to the groove wall of the first receiving groove 211 and the flat surface 213, respectively. The second guide surface 214 is a slanted surface connecting a groove wall of the second receiving groove 215 and the flat surface 213. In other words, the two sides of the second guide surface 214 are connected to the flat surface 213 and the groove wall of the second receiving groove 215, respectively. The first guide surface 212, the flat surface 213, and the second guide surface 214 can be collectively referred to as a protruding region. More specifically, in the axial direction x, the first receiving groove 211 and the second receiving groove 215 are recessed deeper than the protruding region relative to the first surface 204. In the axial direction x, the flat surface 213 is closer to the first surface 204 than the first guide surface 212 and the second guide surface 214.

[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 connected to the side wall surface 211b and the flat surface 213, respectively. 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 connected to the flat surface 213 and the side wall surface 215b, respectively.

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

[0047] In some alternative embodiments, the first receiving groove 211 and the second receiving groove 215 are perforations that penetrate the first surface 204.

[0048] Please refer to Figure 4 and Figure 5 . Figure 5 is Figure 2 a partial perspective view of the support assembly 10 of Figure 4 In the present embodiment, the stopper 200 rotates around the axis A relative to the first plate 110. During the rotation of the stopper 200 from the closed position (as shown in Figure 5 ) to the open position (as shown in Figure 5 ), the stopper block 140 slides along the arcuate groove 210. First, the stopper block 140 disengages from the first receiving groove 211. Next, the stopper block 140 slides against the raised region (the first guide surface 212, the flat surface 213 and the second guide surface 214) in an interference fit manner. Next, the stopper block 140 enters the second receiving groove 215. As shown in , the stopper 200 is fixed in the open position and cannot be rotated relative to the support frame 100 arbitrarily due to the engagement of the stopper block 140 in the second receiving groove 215. Accordingly, the stopper 200 can be selectively fixed in the closed position or the open position by the interaction between the stopper block 140 and the arcuate groove 210.

[0049] Figure 4 The following will describe in detail the sliding of the stopper block 140 over the raised region in an interference fit manner during the rotation of the stopper 200 from the closed position (as shown in Figure 5 ) to the open position (as shown in Figure 4 ). Please refer to Figure 5In this embodiment, first, the limiting bump 140 abuts against the side wall surface 211b. Next, the limiting bump 140 is forced to slide over the side wall surface 211b in a manner of interference fit and contacts the first guide surface 212. Next, after the limiting bump 140 slides over the side wall surface 211b in a manner of interference fit, the limiting bump 140 slides onto the flat surface 213 by the guidance of the first guide surface 212. In the axial direction x, since the distance between the flat surface 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 bump 140 and the flat surface 213. Next, after sliding over the flat surface 213 in a manner of interference fit, the limiting bump 140 slides into the second receiving groove 215 by the guidance of the second guide surface 214. In summary, the protruding region can increase the resistance for the limiting bump 140 to slide 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 to cause the electronic components to fall and be damaged.

[0050] In some embodiments, it is worth mentioning that, in the process of rotating the limiting member 200 from the closed position to the open position relative to the first plate body 110, the resistance between the arc-shaped groove 210 and the limiting bump 140 is first gradually increased and then gradually decreased. In more detail, during the sliding of the limiting bump 140 from the first receiving groove 211 to the flat surface 213, the resistance between the arc-shaped groove 210 and the limiting bump 140 gradually increases with the slope of the first guide surface 212, and has the maximum resistance at the flat surface 213. During the sliding of the limiting bump 140 from the flat surface 213 to the second receiving groove 215, the resistance between the arc-shaped groove 210 and the limiting bump 140 gradually decreases with the slope of the second guide surface 214.

[0051] The following will be described in detail in the process of rotating the limiting member 200 from the open position (as shown in FIG. 2B) to the closed position (as shown in FIG. 2A) relative to the first plate body 110, the limiting bump 140 slides over the protruding region in a manner of interference fit. Please continue to refer to FIGS. 2A-2D. Figure 5 Figure 4 Figure 4 Figure 5 ​​​In this embodiment, first, the limiting bump 140 abuts against the side wall surface 215b. Next, the limiting bump 140 is forced to slide over the side wall surface 215b in a manner of interference fit and contacts the second guide surface 214. Next, after the limiting bump 140 slides over the side wall surface 215b in a manner of interference fit, the limiting bump 140 is guided by the second guide surface 214 to slide onto the flat surface 213. Next, the limiting bump 140 is forced to slide over the flat surface 213 in a manner of interference fit. Next, the limiting bump 140 is guided by the first guide surface 212 to slide into the first receiving groove 211, so that the limiting member 200 is fixed at the closed position. From the above description, it can be seen that the first guide surface 212 and the second guide surface 214 can make the sliding of the limiting bump 140 in the arc-shaped groove 210 more smooth.

[0052] In some embodiments, it is worth mentioning that, in the process of rotating the limiting member 200 from the open position to the closed position relative to the first plate body 110, the resistance between the arc-shaped groove 210 and the limiting bump 140 is first gradually increased and then gradually decreased. In more detail, during the sliding of the limiting bump 140 from the second receiving groove 215 to the flat surface 213, the resistance between the arc-shaped groove 210 and the limiting bump 140 gradually increases with the slope of the second guide surface 214, and has the maximum resistance at the flat surface 213. During the sliding of the limiting bump 140 from the flat surface 213 to the first receiving groove 211, the resistance between the arc-shaped groove 210 and the limiting bump 140 gradually decreases with the slope of the first guide surface 212.

[0053] It should be noted that, in some alternative embodiments, the convex region can not include the first guide surface 212 and the second guide surface 214. The two sides of the flat surface 213 are connected with the groove walls of the first receiving groove 211 and the second receiving groove 215, respectively. Since the convex region does not include the guide surfaces, the convex region can provide greater resistance to make the limiting member 200 more difficult to rotate. In other alternative embodiments, the convex region can not include the first guide surface 212. Since the convex region includes the second guide surface 214 but not the first guide surface 212, the limiting member 200 can be conveniently rotated from the open position back to the closed position, but is not easy to rotate from the closed position to the open position. The effect of not easily opening the limiting member 200 to cause the sheet to fall due to impact or shaking can be achieved.

[0054] Please refer to Figure 6 and Figure 7 . Figure 6 is a bottom view of the fixing frame assembly 10 of an embodiment of the present application. Figure 7 is Figure 6Figure 2A is a schematic view of a cross-sectional structure of the fixing frame assembly 10 viewed along the cutting plane line 7-7. In the present embodiment, the first surface 204 is opposite to the second surface 104 in the axial direction x. The first distance D1 is the distance between the first surface 204 and the second surface 104 in the axial direction x. The second distance D2 is the distance between the plane 213 and the end of the sidewall of the first receiving groove 211 opposite to the bottom in the axial direction x. More specifically, the second distance D2 is the distance between the plane 213 and the end of the sidewall surface 211b of the first receiving groove 211 opposite to 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 (connecting the plane 213) and the lowest point of the first guide surface 212 in the axial direction x (connecting the sidewall surface 211b of the first receiving groove 211). Since the second distance D2 is equal to the first distance D1, the stopper block 140 can be closely fitted in the arc-shaped groove 210 during the operation of the interference between the stopper 200 and the first plate body 110. The closely fitted stopper block 140 and the arc-shaped groove 210 can facilitate the sliding of the stopper 200 and prevent the stopper 200 from being easily bounced off due to impact and thus falling off. In some alternative embodiments, the second distance D2 can be smaller than the first distance D1 in order to provide greater resistance to prevent the stopper 200 from being detached from the closed position.

[0055] Please refer to Figure 6 and Figure 7 In some embodiments, the first guide surface 212 has a third distance D3 between the end connecting the sidewall 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 stopper block 140 can be buffered in the first receiving groove 211 without resistance, and plastic deformation of the stopper 200 caused by long-term compression can be avoided.

[0056] Please refer to Figure 8 . Figure 8 for Figure 6Fig. 6 is a schematic view of a cross-sectional structure of the fixing frame assembly 10 viewed along the cutting surface line 8-8. In the present embodiment, the first surface 204 also has a first distance D1 in the axial direction x from the second surface 104. The end of the groove wall of the second accommodating groove 215 away from the groove bottom has a fourth distance D4 in the axial direction x from the plane 213. In more detail, the end of the plane 213 away from the side wall surface 215b of the second accommodating groove 215 has the fourth distance D4 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 (connected at the plane 213) and the lowest point of the second guide surface 214 in the axial direction x (connected at the side wall surface 215b of the second accommodating groove 215). Since the fourth distance D4 is equal to the first distance D1, the limiting block 140 can closely fit the arc-shaped groove 210 during the operation of the interference of the limiting member 200 and the first plate body 110.

[0057] Please continue to refer to Figure 8 In some embodiments, the second guide surface 214 has a fifth distance D5 between the end of the side wall surface 211b and the bottom surface 215a of the second accommodating 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 block 140 can be buffered in the second accommodating groove 215 without resistance, and plastic deformation of the limiting member 200 caused by long-term compression can be avoided.

[0058] In an embodiment of the present application, the fixing frame assembly 10 of the present application can be arranged in a server, which can be used for artificial intelligence (AI) operation, edge operation, and can also be used as a 5G server, a cloud server, or a vehicle networking server.

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

[0060] The foregoing description is only for illustrative examples of the present application and is not intended to exhaust or limit the precise form of the invention disclosed. The above teachings can be modified or changed.
