[0037] Wireless devices are generally fixed to structures such as walls through brackets, and the angle of the device can be adjusted by adjusting the rotating structure on the bracket. In existing brackets, the rotating structures of different rotation directions are usually provided with different locking mechanisms. For example, the horizontal and pitch directions of the device are respectively controlled by the horizontal locking mechanism and the pitch locking mechanism, and the number of parts is relatively large. In addition, when adjusting the angle of the device, it is necessary to unlock multiple locking mechanisms in order to adjust the device in multiple directions, which is inconvenient to operate.

[0038] In order to solve the above problems, Figures 1 to 6 As shown, the utility model provides a bracket assembly to reduce the number of parts and simplify the adjustment steps.

[0039] like Figures 1 to 6As shown, specifically, the bracket assembly includes a bracket 1, a rotating member 2, a connecting member 3 and a locking member 4, wherein: the bracket 1 is used to be connected to an external structure such as a wall or a ceiling, the rotating member 2 is connected to the bracket 1, and can rotate relative to the bracket 1 around a first preset axis a, and the rotating member 2 is provided with a first anti-rotation portion 21; the connecting member 3 is used to be connected to the wireless device body, the connecting member 3 is connected to the rotating member 2, and can rotate relative to the rotating member 2 around a second preset axis b, the second preset axis b and the first preset axis a form an angle with each other, and the connecting member 3 is provided with A second stop portion 31 capable of cooperating with the first stop portion 21; the locking member 4 is connected to the connecting member 3 and the rotating member 2, and has a locked state and an unlocked state. In the locked state, the locking member 4 tightens the connecting member 3, the rotating member 2 and the bracket 1, so that the first stop portion 21 cooperates with the second stop portion 31 to limit the rotation of the connecting member 3 relative to the rotating member 2, and limit the rotation of the rotating member 2 relative to the bracket 1; in the unlocked state, there is a gap between the connecting member 3, the rotating member 2 and the bracket 1, and the first stop portion 21 is separated from the second stop portion 31.

[0040] In the bracket assembly provided by the embodiment of the utility model, when it is necessary to adjust the angle of the connecting member 3 and the wireless device body connected to the connecting member 3, the locking member 4 is controlled to move to the unlocked state, so that there is a gap between the connecting member 3, the rotating member 2 and the bracket 1, the wireless device body, the connecting member 3 and the rotating member 2 can rotate around the first preset axis a relative to the bracket 1, and the first anti-rotation portion 21 is separated from the second anti-rotation portion 31, the wireless device body and the connecting member 3 can rotate around the second preset axis b relative to the rotating member 2, so that the angle of the connecting member 3 and the wireless device body can be adjusted in two directions; after the adjustment is completed, the locking member 4 is controlled to move to the locked state, so that the locking member 4 connects the wireless device body. The wireless device body, the connecting member 3, the rotating member 2 and the bracket 1 are tightened, and the wireless device body, the connecting member 3 and the rotating member 2 cannot rotate relative to the bracket 1 around the first preset axis a, and the first anti-rotation portion 21 cooperates with the second anti-rotation portion 31, and the wireless device body and the connecting member 3 cannot rotate relative to the rotating member 2 around the second preset axis b, so that the wireless device body and the connecting member 3 are fixed relative to the bracket 1; through a locking member 4, the angle adjustment of the connecting member 3 and the wireless device body relative to the bracket 1 in two directions can be locked or unlocked at the same time, so as to simplify the operation steps, make the angle adjustment of the wireless device body convenient and efficient, and also can reduce the number of parts, so as to simplify the production and disassembly steps of the bracket assembly.

[0041] like Figure 2 and Figure 6As shown, the bracket 1 includes a frame body 11, and the frame body 11 includes a mounting portion 111 and a connecting portion 112 connected to the mounting portion 111. The mounting portion 111 is used to connect to an external structure such as a wall or ceiling, and the connecting portion 112 is used to connect to the rotating member 2. The mounting portion 111 can be installed on an external structure such as a wall or ceiling using one or more expansion screws 6 to ensure the stability and reliability of the bracket assembly on the external structure. Specifically, each expansion screw 6 includes an expansion hose 61 and a screw 62. An assembly hole is provided on the external structure. Before installing the mounting portion 111, the expansion hose 61 is first inserted into the assembly hole, and then the screw 62 is passed through the mounting portion 111 and fixedly connected to the expansion hose 61.

[0042] like Figure 1 and Figure 3 As shown, in one embodiment, the first preset axis a is perpendicular to the second preset axis b, that is, the first preset axis a and the second preset axis b are 90° to each other. Thus, the angle adjustment of the connector 3 and the wireless device body in the pitch direction and the horizontal direction can be achieved through the bracket assembly, so that the connector 3 and the wireless device body can meet a variety of different orientation requirements. For example, the first preset axis a can be extended in the vertical direction, so that when the wireless device body, the connector 3 and the rotating member 2 rotate together relative to the bracket 1 around the first preset axis a, the angle of the connector 3 and the wireless device body in the horizontal direction can be adjusted; the second preset axis b can be extended in the horizontal direction, and when the wireless device body and the connector 3 rotate relative to the rotating member 2 around the second preset axis b, the angle of the connector 3 and the wireless device body in the pitch direction can be adjusted. Alternatively, the first preset axis a can be extended in the horizontal direction, and the second preset axis b can be extended in the vertical direction.

[0043] Of course, in other embodiments, the first preset axis a and the second preset axis b may also be at other angles such as 80°, 70°, 60°, etc., as long as the bracket 1, the rotating member 2, the connecting member 3 and the wireless device body do not interfere with each other during the adjustment of the angle of the connecting member 3 and the wireless device body, and the embodiments of the present utility model are not specifically limited here.

[0044] like Figures 2 to 3 As shown, the connecting member 3 is provided with a sleeve portion 32 extending along the second preset axis b, and the sleeve portion 32 is rotatably sleeved on one end of the rotating member 2. The sleeve portion 32 is sleeved on the rotating member 2, and when the sleeve portion 32 is controlled to rotate relative to the rotating member 2 around the second preset axis b, the inner wall of the sleeve portion 32 can contact the outer wall of the rotating member 2, so as to ensure the stability of the connecting member 3 and the wireless device body when rotating relative to the rotating member 2, and prevent the connecting member 3 and the wireless device body from accidentally falling off.

[0045] like Figures 4 to 5As shown, the first anti-rotation part 21 is arranged at one end of the rotating member 2 extending into the sleeve part 32, and the second anti-rotation part 31 is arranged at the inner bottom wall of the sleeve part 32. In the locked state, the locking member 4 tightens the rotating member 2 and the connecting member 3, so that the end of the rotating member 2 extending into the sleeve part 32 is in close contact with the inner bottom wall of the sleeve part 32, and the first anti-rotation part 21 cooperates with the second anti-rotation part 31 to limit the rotation of the wireless device body and the connecting member 3 relative to the rotating member 2 around the second preset axis b. In the unlocked state, there is a certain distance between the end of the rotating member 2 extending into the sleeve part 32 and the inner bottom wall of the sleeve part 32, and the first anti-rotation part 21 is separated from the second anti-rotation part 31, so that the wireless device body and the connecting member 3 can rotate relative to the rotating member 2 around the second preset axis b.

[0046] In one embodiment, the first stopper 21 and the second stopper 31 are configured as mutually meshing latches. Since the rotating member 2 and the connecting member 3 cannot slide relative to each other along the second preset axis b in the locked state, the first stopper 21 and the second stopper 31 can be ensured to always be meshed with each other. Moreover, when the first stopper 21 and the second stopper 31 are meshed with each other, even if a large force is applied to the connecting member 3, the connecting member 3 cannot be controlled to rotate relative to the rotating member 2 around the second preset axis b, thereby ensuring the stability and reliability of the wireless device body and the connecting member 3 in the locked state.

[0047] Of course, in other embodiments, the first anti-rotation portion 21 and the second anti-rotation portion 31 can also be set to a rough surface, so as to increase the friction between the rotating member 2 and the sleeve portion 32 when one end of the rotating member 2 extends into the sleeve portion 32 and is in close contact with the inner bottom wall of the sleeve portion 32, thereby limiting the connection member 3 from rotating around the second preset axis b relative to the rotating member 2. Alternatively, the first anti-rotation portion 21 and the second anti-rotation portion 31 can also limit the connection member 3 from rotating around the second preset axis b relative to the rotating member 2 by other means such as plug-in matching, and the embodiment of the utility model does not make specific restrictions here.

[0048] like Figures 4 to 5 As shown, in one embodiment, the locking member 4 includes a first threaded portion 41, and one end of the rotating member 2 extending into the sleeve portion 32 is provided with a first threaded hole 22, and the first threaded portion 41 can pass through the bottom wall of the sleeve portion 32 and be connected to the first threaded hole 22 by threading. When the first threaded portion 41 is tightened, the rotating member 2 and the sleeve portion 32 can be pulled tight against each other, so that the end of the rotating member 2 extending into the sleeve portion 32 is in close contact with the inner bottom wall of the sleeve portion 32, so as to limit the connection member 3 from rotating around the second preset axis b relative to the rotating member 2; when the first threaded portion 41 is loosened, there is a certain distance between the end of the rotating member 2 extending into the sleeve portion 32 and the inner bottom wall of the sleeve portion 32, so that the connection member 3 can rotate around the second preset axis b relative to the rotating member 2. The adjustment method of the locking member 4 is simple and convenient, and is easy for users to operate.

[0049] Of course, in other embodiments, a first threaded column may be protruding from one end of the rotating member 2 extending into the sleeve portion 32, and the first threaded column can pass through the bottom wall of the sleeve portion 32. The locking member 4 includes a first nut, and the first nut can be threadedly connected to the first threaded column extending out of the sleeve portion 32 to tighten the rotating member 2 and the sleeve portion 32 when the first nut is tightened.

[0050] like Figure 1 to Figure 2 As shown, in one embodiment, the connector 3 also includes a shell 33 connected to the sleeve portion 32, and the wireless device body can be installed in the shell 33 to protect the wireless device body through the shell 33. The sleeve portion 32 and the shell 33 can be an integrally formed structure to ensure the stability and reliability of the connection between the sleeve portion 32 and the shell 33; of course, the sleeve portion 32 and the shell 33 can also be a split structure, and are fixed by screwing, clamping or gluing. In other embodiments, the connector 3 may not include the shell 33, and the body is directly or indirectly connected to the sleeve portion 32 through other connection structures.

[0051] like Figure 2 and Figure 4 As shown, the bracket 1 also includes a rotating shaft 12 arranged on the connecting portion 112 of the bracket body 11, and the rotating member 2 is provided with an axial hole 23 extending along the first preset axis a, and the rotating member 2 is rotatably sleeved on the rotating shaft 12 through the axial hole 23. The rotating shaft 12 can limit the rotating axis of the rotating member 2 relative to the bracket 1, and the rotating member 2 is sleeved on the rotating shaft 12 through the axial hole 23. When the rotating member 2 is controlled to rotate around the first preset axis a relative to the rotating shaft 12, the inner wall of the axial hole 23 can contact the outer wall of the rotating shaft 12 to ensure the stability of the rotating member 2, the connecting member 3 and the wireless device body when rotating relative to the rotating shaft 12. Among them, the rotating shaft 12, the connecting portion 112 and the mounting portion 111 can be an integrally formed structure to ensure the stability and reliability of the connection between the rotating shaft 12, the connecting portion 112 and the mounting portion 111; of course, the rotating shaft 12, the connecting portion 112 and the mounting portion 111 can also be a split structure, and fixed by screwing, clamping or gluing.

[0052] like Figures 4 to 5 As shown, in one embodiment, in the locked state, the rotating shaft 12, the rotating member 2 and the sleeve portion 32 are mutually tightened, and the end surface of the sleeve portion 32 facing the rotating member 2 and the inner wall of the shaft hole 23 are both in close contact with the outer wall of the rotating shaft 12. Therefore, the end surface of the sleeve portion 32 facing the rotating member 2 and the inner wall of the shaft hole 23 can clamp the rotating shaft 12, so as to increase the friction between the sleeve portion 32 and the inner wall of the shaft hole 23 and the rotating shaft 12, and limit the wireless device body, the connecting member 3 and the rotating member 2 from rotating around the first preset axis a relative to the rotating shaft 12.

[0053] Of course, in other embodiments, the first threaded hole 22 can also be connected to the shaft hole 23. When the first threaded portion 41 is tightened, it can extend out of the first threaded hole 22 and abut against the outer wall of the rotating shaft 12 to increase the friction between the first threaded portion 41 and the rotating shaft 12, thereby limiting the rotation of the wireless device body, the connecting member 3 and the rotating member 2 relative to the rotating shaft 12 around the first preset axis a.

[0054] like Figures 4 to 5 As shown, in one embodiment, the bracket assembly further includes a fastener 5, the fastener 5 includes a second threaded portion 51, and one end of the rotating shaft 12 inserted into the shaft hole 23 is provided with a second threaded hole 122, and the second threaded portion 51 can pass through the rotating member 2 and be threadedly connected to the second threaded hole 122. The fastener 5 can facilitate the user to disassemble and assemble the rotating member 2 and the bracket 1, and can prevent the rotating member 2 from accidentally falling off the rotating shaft 12, thereby ensuring the reliability of the connection between the rotating member 2 and the bracket 1. It can be understood that the fastener 5 is not completely tightened, or the fastener 5 is not in close contact with the rotating member 2 in the tightened state, so as to ensure that the fastener 5 does not affect the rotation of the rotating member 2 relative to the rotating shaft 12 around the first preset axis a.

[0055] Of course, in other embodiments, the second threaded column may be protruded from one end of the rotating shaft 12 inserted into the shaft hole 23, the shaft hole 23 may be a through hole, the second threaded column may pass through the shaft hole 23, and the fastener 5 may include a second nut, which may be threadedly connected to the second threaded column extending from the shaft hole 23. Similarly, the second nut is not completely tightened with the second threaded column, or the second nut is not in close contact with the rotating member 2 when the second nut is tightened with the second threaded column, so as to ensure that the fastener 5 does not affect the rotation of the rotating member 2 relative to the rotating shaft 12 around the first preset axis a.

[0056] like Figures 4 to 5 As shown, the outer wall of the rotating shaft 12 is provided with a first step portion 121, and the inner wall of the shaft hole 23 is provided with a second step portion 231 that can cooperate with the first step portion 121 to limit the relative sliding of the rotating shaft 12 and the rotating member 2 along the first preset axis a. In one embodiment, the rotating shaft 12 and the rotating member 2 are detachably connected by a fastener 5, the first step portion 121 faces the fastener 5, and the second step portion 231 faces the connecting portion 112, so that the first step portion 121 cooperates with the second step portion 231 to limit the sliding of the rotating member 2 relative to the rotating shaft 12 along the first preset axis a toward the side close to the connecting portion 112, and the fastener 5 limits the sliding of the rotating member 2 relative to the rotating shaft 12 along the first preset axis a toward the side away from the connecting portion 112, thereby improving the stability and reliability of the connection between the rotating member 2 and the bracket 1.

[0057] Of course, in other embodiments, the shaft 12 and the rotating member 2 may also be non-detachable, and the number of the first step portions 121 and the second step portions 231 are both two, and the two first step portions 121 are separated from each other, and the two second step portions 231 are also separated from each other. The first step portion 121 toward the fastener 5 cooperates with the second step portion 231 toward the connecting portion 112 to limit the rotating member 2 from sliding relative to the shaft 12 along the first preset axis a toward the side close to the connecting portion 112, and the first step portion 121 toward the connecting portion 112 cooperates with the second step portion 231 toward the fastener 5 to limit the rotating member 2 from sliding relative to the shaft 12 along the first preset axis a toward the side away from the connecting portion 112.

[0058] like Figure 1 As shown, the embodiment of the utility model further provides a wireless device, including a wireless device body and the above-mentioned bracket assembly. The wireless device body can be installed in the housing 33 of the connector 3, or can be connected to the sleeve portion 32 of the connector 3. The wireless device as a whole is installed on an external structure such as a wall or ceiling through the mounting portion 111 of the bracket 1. Of course, the bracket assembly can also be used for other devices such as cameras, lights, sensors, alarms, speakers, etc., as long as they can be installed on external structures such as walls or ceilings through the bracket assembly, and the embodiment of the utility model does not make specific restrictions here.

[0059] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
