Description

Technical Field

[0001] This application relates to the field of communication equipment, and more particularly to a mounting bracket and terminal system. Background Technology

[0002] With the large-scale deployment of 5G mobile communication technology, the demand for various outdoor terminal devices has surged. These devices include, but are not limited to, 5G CPE (Customer Premises Equipment), wireless access points, and miniaturized base stations. These devices are widely deployed on building exteriors, window sills, roofs, and other load-bearing structures to perform functions such as transmitting and receiving wireless signals.

[0003] The prerequisite for the stable operation of these outdoor terminal devices is that they are securely and reliably fixed in their pre-set installation positions. Therefore, the reliability of the mounting bracket, as a key structural component connecting the terminal devices to the load-bearing structure, directly determines the operational stability, signal quality, lifespan, and even the safety of the entire system. Thus, there is an urgent need to provide a highly reliable mounting bracket. Summary of the Invention

[0004] This application discloses a mounting bracket and terminal system to at least solve the problem of poor reliability of mounting brackets in related technologies.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows: In a first aspect, embodiments of this application disclose a mounting bracket for mounting a terminal device on a carrier, the carrier including a carrier body and an extension portion protruding from the carrier body, and the mounting bracket including a mounting body, a first clamping portion, a second clamping portion, and a supporting portion; The mounting body is used to connect terminal equipment; The first clamping part and the second clamping part are disposed opposite to each other and are respectively connected to the mounting body. The first clamping part and the second clamping part can approach each other to clamp the extension part. The support portion is connected to the mounting body and is used to abut against the surface of the bearing body to support the mounting body.

[0006] Secondly, embodiments of this application disclose a terminal system, which includes a terminal device and the mounting bracket described in the first aspect, wherein the terminal device is connected to the carrier through the mounting bracket.

[0007] The mounting bracket and terminal system disclosed in this application improve upon related technologies. The disclosed mounting bracket is used to mount a terminal device onto a support, which includes a support body and an extension protruding from the support body. The mounting bracket includes a mounting body, a first clamping part, a second clamping part, and a supporting part. By clamping the extension part with the first and second clamping parts, the mounting body and the terminal device can be initially fixed. By abutting the supporting part against the surface of the support body, the mounting body and the terminal device can be further supported and fixed, effectively preventing the extension part from deforming or twisting due to excessive load. Since a stable three-point support structure can be formed between the mounting bracket, the support body, and the extension part, the reliability of the mounting bracket and the terminal device installation is improved, thereby improving the operational stability, signal quality, service life, and security of the terminal device.

Detailed Implementation

[0010] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0011] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and are not limited in number; for example, a first object can be one or more.

[0012] The technical solutions disclosed in the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0013] Please refer to Figures 1 to 9This application discloses a mounting bracket 100, which can be used to mount a terminal device 200 onto a support 300. The terminal device 200 includes, but is not limited to, a 5G CPE, a wireless access point, and a miniaturized base station. Furthermore, the mounting bracket 100 can also be used to install facilities such as surveillance cameras and lighting equipment. The support 300 may include a supporting body 310 and an extension 320, wherein the extension 320 may be disposed on the supporting body 310 and protrude from the supporting body 310. In this embodiment, the supporting body 310 may be a building wall, facade, etc., and the extension 320 may be a window sill, eaves, or other structure protruding from the supporting body 310.

[0014] The aforementioned mounting bracket 100 may specifically include a mounting body 110, a first clamping part 120, a second clamping part 130, and a support part 140. The mounting body 110 serves as the structural foundation of the mounting bracket 100 and is used to connect the terminal device 200. The terminal device 200 and the mounting body 110 can be assembled via bolts, snap-fit ​​connections, or other methods. The first clamping part 120 and the second clamping part 130 are respectively connected to the mounting body 110, and the first clamping part 120 and the second clamping part 130 are arranged opposite to each other on the mounting body 110. The first clamping part 120 and the second clamping part 130 can be brought close together to clamp the extension part 320, thereby initially fixing the terminal device 200 and the mounting body 110 to the extension part 320. It is understood that when it is necessary to remove the mounting body 110 from the extension part 320, the extension part 320 can be released simply by controlling the first clamping part 120 and the second clamping part 130 to move away from each other. The first clamping part 120 and the second clamping part 130 can be a claw structure, a suction cup structure, etc.

[0015] In a specific application scenario, taking the supporting body 310 as a wall and the extension 320 as a window sill as an example, the window sill protrudes from the surface of the wall. The first clamping part 120 and the second clamping part 130 can be used to clamp the window sill, so as to initially fix the terminal device 200 and the mounting body 110 to the window sill. Considering that the load-bearing capacity of the window sill is limited, when the weight of the terminal device 200 and the mounting body 110 is large, the window sill is prone to deformation and bending downwards, which will cause the terminal device 200 and the mounting body 110 to easily fall off the window sill.

[0016] To address the aforementioned issues, a support portion 140 can be provided on the mounting body 110. The support portion 140 and the mounting body 110 can be assembled using bolts, snap-fit ​​connections, or other methods. After the terminal device 200 and the mounting body 110 are initially fixed to the extension portion 320, the support portion 140 can be abutted against the surface of the supporting body 310. In this way, the support portion 140 can use the supporting body 310 as a support point to support the mounting body 110 and the terminal device 200.

[0017] like Figure 1 As shown, when the terminal device 200 and the mounting body 110 are initially fixed to the extension portion 320, due to the angle between the extension portion 320 and the horizontal plane, the terminal device 200 and the mounting body 110 will press down on the extension portion 320 under the action of gravity, causing the extension portion 320 to bend and deform towards the supporting body 310. By providing the support portion 140, the force applied to the extension portion 320 can be distributed to a certain extent, thereby alleviating the problem of deformation of the extension portion 320. The aforementioned support portion 140 can be a rod-shaped, disc-shaped, or similar structure.

[0018] Please continue to refer to this. Figure 1 The connection position between the extension portion 320 and the supporting body 310, the clamping positions of the first clamping portion 120 and the second clamping portion 130 on the extension portion 320, and the supporting position of the supporting portion 140 on the supporting body 310 are equivalent to the three vertices of a triangle. It can be seen that a stable triangular support structure can be formed between the mounting bracket 100, the extension portion 320, and the supporting body 310, thereby improving the reliability of the mounting bracket 100.

[0019] As described above, the mounting bracket 100 disclosed in this application improves upon related technologies. By clamping the extension portion 320 with the first clamping part 120 and the second clamping part 130, initial fixation of the mounting body 110 and the terminal device 200 can be achieved. The support part 140 abuts against the surface of the supporting body 310, further supporting and fixing the mounting body 110 and the terminal device 200, effectively preventing deformation and twisting of the extension portion 320 due to excessive load. Since a stable three-point support structure can be formed between the mounting bracket 100, the supporting body 310, and the extension portion 320, the reliability of the mounting bracket 100 and the terminal device 200 installation is improved, thereby enhancing the operational stability, signal quality, service life, and security of the terminal device 200.

[0020] In one optional embodiment of this application, such as Figures 1 to 6As shown, the first direction and the second direction are first defined as two directions with a preset angle. The preset angle can be in the range of 80°-100°, specifically 80°, 90°, 100°, etc. In this embodiment, the first direction can be a direction perpendicular to the surface of the extension portion 320, and the second direction can be perpendicular to the first direction.

[0021] At least one of the first clamping portion 120 and the second clamping portion 130 can move relative to the mounting body 110 in a first direction, so that the first clamping portion 120 and the second clamping portion 130 can move closer to or further away from each other in the first direction, thereby clamping or releasing the extension portion 320. For example, the first clamping portion 120 or the second clamping portion 130 can move relative to the mounting body 110 in the first direction, or both the first clamping portion 120 and the second clamping portion 130 can move relative to the mounting body 110 in the first direction.

[0022] In different installation scenarios, the thickness of the extension portion 320 (the dimension of the extension portion 320 in the first direction) may not be exactly the same. By controlling at least one of the first clamping portion 120 and the second clamping portion 130 to move relative to the mounting body 110 in the first direction, the distance between the first clamping portion 120 and the second clamping portion 130 can be flexibly adjusted, thereby adapting to extension portions 320 of different thicknesses and realizing flexible installation of the mounting bracket 100.

[0023] Similarly, the support portion 140 can move relative to the mounting body 110 in the second direction, so that the mounting body 110 can move closer to or further away from the surface of the supporting body 310. Specifically, when the position of the mounting body 110 cannot ensure stable contact between the support portion 140 and the surface of the supporting body 310, the support portion 140 can be moved to achieve stable support with the supporting body 310. While ensuring stable contact between the support portion 140 and the supporting body 310, moving the support portion 140 allows the mounting body 110 to move closer to or further away from the surface of the supporting body 310, thereby adjusting the tilt angle of the terminal device 200 (the angle between the central axis direction of the terminal device 200 and the vertical direction).

[0024] The aforementioned first clamping part 120, second clamping part 130, and support part 140 can be slidably connected to the mounting body 110 via structures such as slide rails and linear bearings to achieve movement relative to the mounting body 110. It should be noted that, to ensure the first clamping part 120, second clamping part 130, and support part 140 can be stably maintained in a certain position, a locking structure can be provided on the slide rail, linear bearing, or other structures. The locking structure has a locked state and an unlocked state. When the locking structure is in the unlocked state, the first clamping part 120, second clamping part 130, and support part 140 can move relative to the mounting body 110. When the locking structure is in the locked state, the first clamping part 120, second clamping part 130, and support part 140 are relatively fixed to the mounting body 110. Specifically, the locking structure can employ existing technologies such as electromagnetic locks or the cooperation of pins and pin holes; this embodiment does not limit the specific type of locking structure.

[0025] In an optional embodiment of this application, the first clamping part 120 may include a first clamping disk 121 for clamping the extension part 320, and the second clamping part 130 may include a second clamping disk 131 for clamping the extension part 320. The first clamping disk 121 and the second clamping disk 131 may be used to abut against the upper surface and the lower surface of the extension part 320, respectively, wherein the upper surface and the lower surface of the extension part 320 are two surfaces of the extension part 320 that are opposite to each other in a first direction.

[0026] Considering that the upper and lower surfaces of the extension portion 320 may not be parallel, in layman's terms, the extension portion 320 may not be a plate-like structure with uniform thickness, and the cross-section of the extension portion 320 in the first direction may be wedge-shaped, spindle-shaped, etc., in order to enable the first clamping disk 121 and the second clamping disk 131 to fully contact the upper and lower surfaces of the extension portion 320 respectively to improve the clamping effect, in this embodiment, at least one of the first clamping disk 121 and the second clamping disk 131 is rotatably disposed on the mounting body 110 and can swing relative to the mounting body 110. In other words, the first clamping plate 121 and / or the second clamping plate 131 can be connected to the mounting body 110 through a universal joint structure, so as to flexibly adjust the position of the first clamping plate 121 and the second clamping plate 131, so that the first clamping plate 121 and the second clamping plate 131 can make full contact with the upper surface and the lower surface of the extension portion 320 respectively, thereby improving the stability of the first clamping plate 121 and the second clamping plate 131 in clamping the extension portion 320.

[0027] And / or, the support portion 140 may include a support disk 141 for abutting against the surface of the support body 310. The contact angle between the support disk 141 and the surface of the support body 310 changes as the mounting body 110 approaches or moves away from the surface of the support body 310. To ensure sufficient contact between the support disk 141 and the surface of the support body 310, in this embodiment, the support disk 141 is rotatably disposed on the mounting body 110 and can swing relative to the mounting body 110. That is, the support disk 141 can be connected to the mounting body 110 via a universal joint structure, allowing for flexible adjustment of the position of the support disk 141. This ensures stable contact between the support disk 141 and the surface of the support body 310, thereby improving the reliability of the connection between the support disk 141 and the support body 310.

[0028] The first clamping plate 121, the second clamping plate 131, and the support plate 141 can be connected to the mounting body 110 through structures such as sliding ball joints and universal bearings to achieve the above-mentioned functions.

[0029] In one specific embodiment of this application, the first clamping part 120 may further include a first screw 122, a first operating knob 123, and a first limiting member 124. The mounting body 110 has a first threaded hole, and the first screw 122 can pass through the first threaded hole of the mounting body 110. By rotating the first screw 122, the first screw 122 can move relative to the mounting body 110 in a first direction and rotate about the first direction. The first screw 122 has a first end and a second end facing away from each other. The first operating knob 123 can be connected to the first end of the first screw 122 to facilitate user rotation of the first screw 122. The first operating knob 123 and the first screw 122 can be assembled by welding, pin connection, or other methods.

[0030] The second end of the first screw 122 is provided with a first protrusion 1221, the diameter of which is slightly smaller than the diameter of the first screw 122. The first limiting member 124 can be connected to the first protrusion 1221 by means of bolt connection, snap-fit, etc. The first limiting member 124 can be a machine screw, a pin, etc. Taking a machine screw as an example, a threaded hole can be opened in the first protrusion 1221, and the screw of the machine screw can be screwed into the threaded hole to achieve fixation.

[0031] The first clamping disc 121 has a first cavity 1211 and a first through hole communicating with the first cavity 1211. At least a portion of the first protrusion 1221 can extend into the first cavity 1211 through the first through hole. The diameter of the first through hole is larger than the diameter of the first protrusion 1221. A first limiting member 124 is located in the first cavity 1211, and the diameter of the first limiting member 124 is larger than the diameter of the first through hole, thereby preventing the first protrusion 1221 from dislodging from the first through hole. Since the diameter of the first through hole is larger than the diameter of the first protrusion 1221, the first protrusion 1221 can rotate around its own axis in the first through hole. At the same time, the first protrusion 1221 can also swing in the first through hole, thereby realizing the angle adjustment of the first clamping disc 121. It should be noted that the outer surface of the first protrusion 1221 can be smooth, so the frictional force when the first protrusion 1221 contacts the wall of the first through hole is small, which is conducive to the smooth universal movement of the first clamping plate 121.

[0032] In this embodiment, the second clamping plate 131 can be fixedly connected to the mounting body 110. By controlling the first clamping plate 121 to move in the first direction and swing relative to the mounting body 10, the relative position and clamping angle of the first clamping plate 121 and the second clamping plate 131 can be adjusted.

[0033] In an optional embodiment of this application, the support portion 140 may further include a second screw 142, a second operating knob 143, and a second limiting member 144. The mounting body 110 has a second threaded hole, and the second screw 142 can pass through this hole. By rotating the second screw 142, it can move relative to the mounting body 110 in a second direction and rotate about that direction. The second operating knob 143 can be connected to the first end of the second screw 142 to facilitate user rotation of the second screw 142. The second operating knob 143 and the second screw 142 can be assembled by welding, pin connection, or other methods.

[0034] The second end of the second screw 142 is provided with a second protrusion 1421, the diameter of which is slightly smaller than the diameter of the second screw 142. The second limiting member 144 can be connected to the second protrusion 1421 by means of bolt connection, snap-fit, etc. The second limiting member 144 can be a machine screw, a pin, etc. Taking a machine screw as an example, a threaded hole can be opened in the second protrusion 1421, and the screw of the machine screw can be screwed into the threaded hole to achieve fixation.

[0035] The second clamping disc 131 has a second cavity 1411 and a second through hole communicating with the second cavity 1411. At least a portion of the second protrusion 1421 can extend into the second cavity 1411 through the second through hole. The diameter of the second through hole is larger than the diameter of the second protrusion 1421. The second limiting member 144 is located in the second cavity 1411, and the diameter of the second limiting member 144 is larger than the diameter of the second through hole, thereby preventing the second protrusion 1421 from dislodging from the second through hole. Since the diameter of the second through hole is larger than the diameter of the second protrusion 1421, the second protrusion 1421 can rotate around its own axis in the second through hole. At the same time, the second protrusion 1421 can also swing in the second through hole, thereby realizing the angle adjustment of the second clamping disc 131. It should be noted that, referring to the relevant content of the first protrusion 1221 mentioned above, the outer surface of the second protrusion 1421 can also be smooth. In this case, the frictional force when the second protrusion 1421 contacts the wall of the second through hole is small, which is conducive to the smooth universal movement of the second clamping plate 131.

[0036] In this embodiment, the mounting body 110 can be made of materials such as aluminum or stainless steel using an integral molding process to ensure the structural strength of the mounting body 110. The mounting body 110 may include a base plate 111, a first wing plate 112, a second wing plate 113, and an extension plate 114. The base plate 111 can be used to connect to the terminal device 200. The first wing plate 112 and the second wing plate 113 are respectively connected to both ends of the base plate 111 and extend in a direction away from the base plate 111. A first clamping part 120 can be connected to the first wing plate 112, and a second clamping part 130 can be connected to the second wing plate 113. The first wing plate 112 and the second wing plate 113 can be parallel to each other. The extension plate 114 is connected to the second wing plate 113 and extends from the second wing plate 113 in a direction away from the first wing plate 112. A support part 140 can be connected to the extension plate 114. The mounting body 110 with the above structure facilitates the layout and installation of the first clamping part 120, the second clamping part 130, and the support part 140.

[0037] Furthermore, the second wing plate 113 may include a first plate 1131 and a second plate 1132 connected to each other. The first plate 1131 is connected to one end of the substrate 111 and extends in a direction away from the substrate 111. The second plate 1132 extends toward the first wing plate 112. The second clamping part 130 may be disposed on the second plate 1132. In addition, the end of the second plate 1132 may be further bent to form a flat plate structure for supporting the second clamping part 130, so as to improve the stability of the second clamping part 130 during installation.

[0038] The mounting body 110 may also include a reinforcing plate 115. Both ends of the reinforcing plate 115 are connected to the base plate 111 and the second plate 1132, respectively. The reinforcing plate 115, the base plate 111, and the second plate 1132 can be an integral structure or fabricated separately and then assembled together by bolts, riveting, welding, or other methods. By providing the reinforcing plate 115, the structural strength of the mounting body 110 can be effectively improved. Furthermore, the reinforcing plate 115, the base plate 111, the first plate 1131, and the second plate 1132 can together form a mounting hole 116. During actual installation, the mounting hole 116 is used to pass through a safety rope. After passing through the mounting hole 116, the safety rope can be connected to other load-bearing structures, thereby reducing the risk of the mounting bracket 100 falling.

[0039] In an optional embodiment of this application, at least one of the first clamping plate 121, the second clamping plate 131, and the support plate 141 may be provided with an anti-slip pad 150. The anti-slip pad 150 may be a rubber pad, a silicone pad, etc. To increase the friction of the surface of the anti-slip pad 150, anti-slip structures such as raised dots or patterns may be provided on the surface of the anti-slip pad 150. By providing the anti-slip pad 150, relative sliding between the first clamping plate 121 and the extension portion 320, between the second clamping plate 131 and the extension portion 320, and between the support plate 141 and the bearing body 310 can be effectively prevented, thus avoiding any impact on installation stability.

[0040] like Figure 8 and Figure 9 As shown, due to the large size difference between the mounting body 110 and the terminal device 200, it is not convenient to assemble the mounting body 110 and the terminal device 200. In this embodiment, the mounting bracket 100 may also include an adapter 160. The adapter 160 may be a plate-shaped, block-shaped or other structure. The mounting body 110 can be connected to the terminal device 200 through the adapter 160. Specifically, the mounting body 110 can be assembled with the adapter 160 by bolt connection first, and then the terminal device 200 can be installed on the adapter 160 by using fastening screws and screw holes on the adapter 160.

[0041] Please refer to Figures 1 to 9 This application also discloses a terminal system, which may include a terminal device 200 and the mounting bracket 100 mentioned above. The terminal device 200 can be connected to the carrier 300 through the mounting bracket 100.

[0042] As described above, the mounting bracket 100 and terminal system disclosed in this application improve upon related technologies. By clamping the extension portion 320 with the first clamping part 120 and the second clamping part 130, initial fixation of the mounting body 110 and the terminal device 200 can be achieved. By abutting the support part 140 against the surface of the supporting body 310, further support and fixation of the mounting body 110 and the terminal device 200 can be achieved, effectively preventing deformation and twisting of the extension portion 320 due to excessive load. Since a stable three-point support structure can be formed between the mounting bracket 100, the supporting body 310, and the extension portion 320, the reliability of the mounting bracket 100 and the terminal device 200 installation is improved, thereby enhancing the operational stability, signal quality, service life, and security of the terminal device 200.

[0043] The above embodiments of this application focus on describing the differences between the various embodiments. As long as the different technical features between the various embodiments are not contradictory, they can be combined to form more specific embodiments. For the sake of brevity, they will not be described in detail here.

[0044] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
