It should be understood that the directions "above", "below", "outside" and "inside" are all directions in normal use, and the directions "left" and "right" refer to the left and right directions shown in the corresponding schematic diagrams, which may or may not be the left and right directions in normal use.

[0030] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0031] The embodiment of the present utility model provides a mounting structure for installing a radio frequency remote module. It should be noted that the mounting structure provided by the embodiment of the present utility model is not limited to installing a radio frequency remote module, but can also be used to install other communication modules (such as a small communication cabinet); for ease of understanding, all embodiments of the present utility model are described by taking the installation of a radio frequency remote module as an example. The installation scenario of the radio frequency remote module can be the top of a building such as an outer wall of a building, a utility pole, a gantry in a temporary or specific scenario, to ensure the coverage and transmission effect of the signal; it can also be near a signal tower to be close to the signal source and reduce transmission loss; it can also be an indoor environment such as an indoor ceiling, an indoor wall, an equipment room, a weak current well, etc. For ease of understanding, all embodiments of the present utility model are described by taking the installation of a radio frequency remote module (hereinafter referred to as a module) on the outer wall of a building (hereinafter referred to as an outer wall) as an example.

[0032] like Figure 1 and Figure 2 As shown, the mounting structure 1 includes a bracket 11. The bracket 11 has an inner surface M1 and an outer surface M2 disposed opposite to each other in a first direction. The first portion M11 of the inner surface M1 is used to be close to the outer wall; the second portion M12 of the inner surface M1 is spaced from the outer wall to provide an installation space for the installation of related components; the outer surface M2 is used to be close to the module 2 (refer to Figure 3 ). The projection direction from the inner surface M1 to the outer surface M2 or from the outer surface M2 to the outer surface M2 is a first direction, which is the thickness direction of the bracket 11 and also the thickness direction of the module 2; the first direction is indicated by a double-headed arrow N1 in the figure.

[0033] like Figures 3 to 5 As shown, the method of hanging the module 2 on the external wall can be exemplarily as follows: first, the bracket 11 is fixedly connected to the external wall, specifically, it can be fixed with expansion bolts, so that the first part M11 of the inner surface M1 is close to the external wall; then, the flat head screw is screwed on the module 2, and a reserved gap is formed between the head of the flat head screw and the module 2; then, the flat head screw passes through the through hole in the second part M12 of the inner surface M1 along the first direction, so that the module 2 is close to the external surface M2, and the bracket 11 is in the reserved gap; finally, the flat head screw and the module 2 connected as one are moved along the second direction (the second direction is perpendicular to the first direction, and the second direction is indicated by a double-headed arrow N2 in the figure), and then due to the blocking effect of the head of the flat head screw, the module 2 is hung on the bracket 11, that is, the module 2 is hung on the external wall.

[0034] However, after the module 2 is hung on the bracket 11, the module 2 can still slide relative to the bracket 11, that is, the module 2 cannot be fixed on the bracket 11, so the mounting structure 1 is also provided with a movable member 12 to prevent the module 2 from sliding relative to the bracket 11. In addition, in order to facilitate the removal of the module 2, the movable member 12 can also allow the module 2 to slide relative to the bracket 11. The movable member 12 is described in detail below.

[0035] like Figure 1 and Figure 2 As shown, the connection structure between the movable member 12 and the bracket 11 is as follows: the movable member 12 is connected to the bracket 11, specifically, the bracket 11 may be integrally formed with the movable member 12, or the movable member 12 may be connected to the bracket 11 through a connecting member (such as a screw). The bracket 11 has a first through hole 111 opened along a first direction, and the movable member 12 is inserted into the first through hole 111. Accordingly, the movable member 12 is connected to the second portion M12 of the inner surface M1 of the bracket 11.

[0036] like Figure 5 and Figure 6 As shown, at least part of the movable member 12 can reciprocate along the first direction relative to the bracket 11. It can be understood that either part of the movable member 12 reciprocates along the first direction relative to the bracket 11, or the movable member 12 as a whole reciprocates along the first direction relative to the bracket 11. At least part of the movable member 12 protrudes from the first through hole 111 with the reciprocating motion to engage with the module 2 and retracts from the first through hole 111 to disengage from the module 2. Figure 5 As shown, when the movable member 12 protrudes from the first through hole 111 to one side of the outer surface M2 of the bracket 11, the movable member 12 is engaged with the module 2, thereby preventing the module 2 from sliding relative to the bracket 11 and fixing the module 2; Figure 6 As shown, when the movable part 12 is retracted from the first through hole 111, that is, the movable part 12 is flush with the outer surface M2 or the movable part 12 leaves the outer surface M2, the movable part 12 disengages from the module 2, thereby allowing the module 2 to slide relative to the bracket 11, facilitating the subsequent disassembly of the module 2.

[0037] The mounting structure 1 for the module 2 provided in the embodiment of the utility model comprises a bracket 11 and a movable member 12; the bracket 11 has a first through hole 111 opened along a first direction, the movable member 12 is connected to the bracket 11, and at least a portion of the movable member 12 can reciprocate along the first direction relative to the bracket 11; wherein at least a portion of the movable member 12 protrudes from the first through hole 111 with the reciprocating motion to engage with the module 2 and retracts from the first through hole 111 to disengage from the module 2. The embodiment of the utility model provides the bracket 11 and the movable member 12, and the reciprocating motion of the movable member 12 on the bracket 11 can realize the clamping fixation and release of the clamping fixation with the module 2, without the need for additional tools or parts to realize the installation and removal of the module 2, thereby simplifying the installation operation of the module 2.

[0038] In addition, the snap-fit ​​connection between the movable part 12 and the module 2 in the embodiment of the utility model reduces the use of screws, thereby reducing the risk of the module 2 being unable to be firmly fixed on the bracket 11 due to wear, deformation or damage of the screw threads, and reduces the risk of the screws loosening or falling off.

[0039] In some embodiments, Figure 7 As shown, the movable member 12 includes an elastic arm 121 and a barb 122. Since the elastic arm 121 is elastic, at least a portion of the elastic arm 121 forms a reciprocating motion during the process of deformation and restoration of the elastic arm 121. One or more barbs 122 may be provided; the shape of the barb 122 is not limited to the plate-like structure shown in FIG. 7, but may also be a cylindrical structure, or may be other structures.

[0040] In order to make the barb 122 reciprocate with the elastic arm 121, the specific connection structure of the barb 122 and the elastic arm 121 is as follows: Figure 4As shown, the elastic arm 121 is connected to the inner surface M1 of the bracket 11 (the inner surface M1 of the bracket 11 is far away from the module 2), specifically connected to the second part M12 of the inner surface M1 of the bracket 11. The barb 122 is arranged on the elastic arm 121, and the connection position of the barb 122 and the elastic arm 121 is separated from the connection position of the elastic arm 121 and the bracket 11 by a preset distance. The preset distance can be greater than zero, and the larger the preset distance, the larger the amplitude of the reciprocating motion of the barb 122 with the elastic arm 121. Therefore, in order to make the amplitude of the reciprocating motion of the barb 122 large, the connection position of the barb 122 and the elastic arm 121 is located at the first end 121A of the elastic arm 121, and the connection position of the elastic arm 121 and the bracket 11 is located at or close to the second end 121B of the elastic arm 121; or, in the extension direction of the elastic arm 121, the distance from the barb 122 to the second end 121B is less than the distance from the barb 122 to the first end. The first end 121A and the second end 121B are opposite ends of the extension direction of the elastic arm 121. The extension direction of the elastic arm 121 is indicated by a dotted line a in the figure, and the extension direction of the elastic arm 121 changes as the elastic arm 121 reciprocates.

[0041] Figure 5 and Figure 6 As shown, the projection of the barb 122 in the first direction is located within the projection of the first through hole 111 in the first direction. The barb 122 can pass through the first through hole 111 to engage with the module 2 during the reciprocating movement of the elastic arm 121 in the first direction, thereby preventing the module 2 from moving relative to the bracket 11; and can be retracted from the first through hole 111 to disengage from the engagement with the module 2, thereby allowing the module 2 to move relative to the bracket 11. Since the elastic arm 121 is on the inner surface M1 of the bracket 11 (refer to Figure 4 ), and the module 2 is on the side of the outer surface M2 of the bracket 11, then no matter whether the barb 122 is engaged with the module 2 or detached from the module 2, the module 2 can be closely attached to the outer surface M2 of the bracket 11, making the overall structure compact. Among them, the inner wall of the first through hole 111 acts as a limit for the barb 122, which can reduce the shaking of the barb 122 during the reciprocating motion.

[0042] The embodiment of the utility model forms a movable part 12 by connecting the elastic arm 121 and the barb 122 as a whole, and uses the reciprocating part of the elastic arm 121 to drive the barb 122 to reciprocate; and the elastic arm 121 is on one side of the inner surface M1 of the bracket 11, so that the module 2 can be closely attached to the outer surface M2 of the bracket 11, and the structure is compact.

[0043] In some embodiments, Figure 5 and Figure 7As shown, the end of the barb 122 for extending out of the first through hole 111 is formed with an inclined surface M3, and the inclined surface M3 intersects with the extension direction of the elastic arm 121 to form an acute angle. The inclined surface M3 has a proximal end M3A close to the elastic arm 121 and a distal end M3B away from the elastic arm 121. When the barb 122 extends out of the first through hole 111, the proximal end M3A of the barb 122 is located in the first through hole 111 (such as Figure 5 As shown in the figure, the first through hole 111 is slightly extended from the first through hole 111 or is flush with the first through hole 111, so that the module 2 can pass over the proximal end M3A of the barb 122. Based on the elastic arm 121, the distal end M3B of the barb 122 is more prominent than the proximal end M3A, so as to extend deeper into the module 2 to achieve stable clamping.

[0044] like Figure 5 and Figure 7 As shown, during the process of the module 2 being engaged with the barb 122, the module 2 slides close to the outer surface M2 of the bracket 11, and the engaging portion of the module 2 (the engaging portion of the module 2 is the portion for engaging with the barb 122) first presses and passes over the proximal end M3A of the barb 122, and then presses and passes over the distal end M3B of the barb 122 until engaging with the barb 122. In this way, the module 2 slides relative to the bracket 11, and the engaging portion of the module 2 with the barb 122 is completed.

[0045] In the embodiment of the utility model, by setting the inclined surface M3 of the barb 122, the module 2 slides closely against the bracket 11, and the module 2 and the barb 122 can be connected, which is convenient to operate.

[0046] In some embodiments, Figure 4 and Figure 7 As shown, the connection position between the elastic arm 121 and the inner surface M1 is located at the first end 121A in the extension direction of the elastic arm 121; Figure 5 As shown, the second end 121B of the elastic arm 121 in the extension direction exceeds the inner surface M1 , and the second end 121B exceeding the inner surface M1 can be observed and easily touched.

[0047] The second end 121B extending beyond the inner surface M1 has the following function: when disassembling the module 2, in order to disengage the module 2 from the engagement with the barb 122, the elastic arm 121 needs to be lifted to retract the barb 122 into the first through hole 111. At this time, the second end 121B of the elastic arm 121 extending beyond the inner surface M1 is pushed manually or with the aid of a tool, and when the elastic arm 121 is lifted, the barb 122 retracts into the first through hole 111 accordingly.

[0048] In some embodiments, Figure 1 As shown, the inner surface M1 of the bracket 11 is provided with a limiting member 13. Figures 5 to 7As shown, the stopper 13 is used to block the movement of the elastic arm 121 in the first direction. It can be understood that, specifically during disassembly, in order to retract the barb 122 into the first through hole 111 and disengage from the clamping of the module 2, it is necessary to push the second end 121B of the elastic arm 121 manually or with the help of a tool so that the second end 121B of the elastic arm 121 gradually moves away from the bottom plate 112. Since the first end 121A of the elastic arm 121 is fixed relative to the bottom plate 112, the entire elastic arm 121 is deformed. If the elastic arm 121 is severely deformed, the elastic arm 121 is at risk of breaking.

[0049] The embodiment of the utility model provides a stopper 13 to block the movement of the second end 121B of the elastic arm 121 in the first direction, thereby reducing the deformation of the elastic arm 121 and the risk of the elastic arm 121 breaking.

[0050] In some embodiments, Figure 5 and Figure 6 As shown, the stopper 13 includes a connecting portion 131 and a stopper 132. One end of the connecting portion 131 is disposed on the inner surface M1 of the bracket 11; the stopper 132 is disposed on the other end of the connecting portion 131; wherein the elastic arm 121 is located between the stopper 132 and the inner surface M1. Thus, the stopper 132 is used to block the movement of the second end 121B of the elastic arm 121 in the first direction.

[0051] For example, the connecting portion 131 and the limiting portion 132 may be formed by stamping the bottom plate 112 , so as to avoid providing a component for connection between the limiting member 13 and the bracket 11 .

[0052] In the embodiment of the utility model, the limiting member 13 including the limiting portion 132 and the connecting portion 131 is provided to limit the elastic arm 121 between the limiting portion 132 and the bottom plate 112 . The limiting member 13 has a simple structure and is easy to implement.

[0053] In some embodiments, Figure 1 As shown, the bracket 11 includes a bottom plate 112 and a side plate 113. The bottom plate 112 has an inner surface and an outer surface arranged opposite to each other in a first direction. The inner surface of the bottom plate 112 is the second part M12 of the inner surface M1 of the bracket 11, and the outer surface of the bottom plate 112 is a part of the outer surface M2 of the bracket 11. The first through hole 111 is opened in the bottom plate 112. The side plate 113 is connected to the edge of the bottom plate 112 and is located on a side close to the inner surface of the bottom plate 112 in the first direction. Among them, the outer surface of the bottom plate 112 is used to set the module 2 (refer to Figure 3), the side plate 113 and the bottom plate 112 form a cavity 110 for accommodating the movable part 12. The cavity 110 can also be used to accommodate other components, such as the limiter 13 and the flap 5 formed after the bottom plate 112 is stamped (the formation of the flap 5 can form an avoidance position, etc., so that the bracket 11 is suitable for modules 2 of other forms of structure). The setting of the cavity 110 in the embodiment of the utility model allows the movable part 12 and other components connected to the bracket 11 to avoid the outer wall and avoid interference with the outer wall.

[0054] In some embodiments, Figure 1 As shown, the bottom plate 112 is further provided with a second through hole 114 along the first direction. The length direction of the second through hole 114 is consistent with the length direction of the bottom plate 112. Since the length direction of the second through hole 114 is parallel to the second direction, the length direction of the second through hole 114, the length direction of the bottom plate 112, and the second direction are parallel to each other. The width of the second through hole 114 varies in the length direction, and the width direction of the second through hole 114 is indicated by a double-headed arrow N3 in the figure.

[0055] like Figure 4 As shown, the second through hole 114 is used for the connector 4 to connect the bracket 11 and the module 2 and to detach the bracket 11 and the module 2, that is, the second through hole 114 is used to hang the module 2 on the bracket 11. The operation steps can refer to the method for hanging the module 2 on the exterior wall mentioned in the above embodiment. The flat head screw in this method belongs to the connector 4 in the embodiment of the utility model.

[0056] In some embodiments, Figure 4 and Figure 7 As shown, the length direction of the second through hole 114 is parallel to the extension direction of the elastic arm 121. In this way, when the connector 4 slides in the second through hole 114 along the length direction of the second through hole 114, the module 2 slides along the extension direction of the elastic arm 121 with the connector 4, and the module 2 presses the barb 122 to deform the elastic arm 121 until the module 2 is engaged with the barb 122.

[0057] like Figure 4 and Figure 7 As shown, the length of the second through hole 114 is greater than or equal to the length of the barb 122 in the first direction. When the connector 4 slides in the second through hole 114 along the second direction, the engaging portion of the module 2 can pass over the barb 122, so that the module 2 can be engaged, and the connector 4 cannot be retracted along the second direction. The appropriate length of the second through hole 114 of the connector 4 makes it impossible for the connector 4 to continue to slide along the second direction when the module 2 is engaged with the barb 122.

[0058] The embodiment of the utility model can make the connector 4 pass through the bottom plate 112 from the position where the second through hole 114 is wide, and then slide to the position where the second through hole 114 is small, so that the connector 4 can be hung on the bottom plate 112, and the module 2 connected to the connector 4 can be hung on the bottom plate 112. In addition, the length direction of the second through hole 114 is parallel to the extension direction of the elastic arm 121, so that the module 2 can be engaged with the barb 122 during the sliding process of the connector 4 in the second through hole 114, and the connector 4 cannot be retracted along the second direction. And, by determining the appropriate length of the second through hole 114, when the module 2 is engaged with the barb 122, the connector 4 cannot continue to slide along the second direction. In this way, the connector 4 is fixed to the bottom plate 112, and the module 2 is fixed to the bottom plate 112.

[0059] In some embodiments, Figure 1 and Figure 6 As shown, the second through hole 114 is disposed on both sides of the first through hole 111. In this way, when the module 2 is suspended on the bottom plate 112, the skew of the module 2 relative to the bottom plate 112 can be reduced.

[0060] In some embodiments, Figure 4 As shown, the second through hole 114 includes a long hole 1141 with a width of a first preset value and a round hole 1142 connected to one end of the long hole 1141 with a diameter of a second preset value, and the second preset value is greater than the first preset value. In this way, after the connecting member 4 passes through the bottom plate 112 from the round hole 1142, it slides toward the long hole 1141, so that the connecting member 4 can be hung on the bottom plate 112.

[0061] In some embodiments, Figure 4 As shown, the second through hole 114 includes a long hole 1141 with a width of a first preset value and a notch 1143 connected to one end of the long hole 1141. The minimum width of the notch 1143 is equal to the first preset value, and the first preset value can be determined according to actual conditions. In this way, after the connecting member 4 passes through the bottom plate 112 from the notch 1143, it slides toward the long hole 1141, so that the connecting member 4 can be hung on the bottom plate 112.

[0062] like Figure 4 As shown, when the second through hole 114 with the notch 1143 is penetrated by the connecting member 4, it can be penetrated not only along the first direction but also along the second direction; while when the second through hole 114 with the round hole 1142 is penetrated by the connecting member 4, it can only be penetrated along the first direction; therefore, the second through hole 114 with the notch 1143 is easier to be penetrated by the connecting member 4 than the second through hole 114 with the round hole 1142. However, the second through hole 114 with the notch 1143 can only be set at the edge of the bottom plate 112, that is, the setting position is limited, while the second through hole 114 with the round hole 1142 does not have this limitation.

[0063] In the embodiment of the utility model, the second through hole 114 with the notch 1143 and / or the second through hole 114 with the round hole 1142 can be provided to allow multiple connectors 4 to pass through, so that the multiple connectors 4 are evenly distributed relative to the bottom plate 112 .

[0064] The present utility model also provides a radio frequency remote device. Figure 3 and Figure 4 As shown, the device includes a mounting structure 1 and a module 2. The module 2 is provided with a card slot 21, and the card slot 21 can be provided with one or more. The card slot 21 is used for the movable part 12 to be inserted to be connected with the bracket 11. The card slot 21 belongs to the card connection part mentioned in the above embodiment. Among them, the card slot 21 can be formed by the heat sink of the module 2, or it can be a separate structure provided on the module 2.

[0065] The mutually clamped fixing method between the mounting structure 1 and the module 2 of the embodiment of the utility model does not require additional tools or parts to realize the installation and removal of the module 2, thereby simplifying the installation operation of the module 2. In some embodiments, such as Figure 4 and Figure 8 As shown, the connector 4 detachably connects the module 2 and the bracket 11, specifically, the rod 42 of the connector 4 is threadedly connected to the module 2. The connector 4 includes an end 41 and a rod 42 connected to the end 41, and the width of the end 41 is greater than the width of the rod 42.

[0066] The width of the end portion 41 is slightly smaller than the diameter of the circular hole of the second through hole 114, so that the end portion 41 can pass through the second through hole 114. The width of the rod portion 42 is slightly smaller than the width of the long hole of the second through hole 114, so that the rod portion 42 can slide in the long hole of the second through hole 114.

[0067] like Figure 4 and Figure 8 As shown, when the connector 4 is connected to the module 2, a certain gap is reserved between the end 41 and the module 2, and the gap is equal to or slightly larger than the thickness of the bottom plate 112 of the bracket 11. In this way, when the connector 4 is suspended on the bottom plate 112 of the bracket 11, the bottom plate 112 can be clamped between the end 41 of the connector 4 and the module 2.

[0068] In the embodiment of the utility model, the width of the end portion 41 of the connector 4 is larger than the width of the rod portion 42 , so that the connector 4 can be hung on the bracket 11 , that is, the module 2 can be hung on the bracket 11 , so as to facilitate the subsequent installation and fixation of the module 2 .

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
