To better illustrate the technical content of the present invention, preferred embodiments are specifically described below.

Fig. 1 is a schematic view of a monitoring system according to an embodiment of the invention, and fig. 2 is an exploded schematic view of the monitoring system shown in fig. 1, please refer to fig. 1 and fig. 2 at the same time. The monitoring system 1 of the present embodiment includes a mounting base 10 and a monitoring device 20. The mounting base 10 is used for mounting the monitoring device 20, i.e. the monitoring device 20 may be mounted to the mounting base 10. After the installation base 10 and the monitoring device 20 are assembled, the installation base 10 may be installed on a wall surface of an environmental space to be monitored or a surface of another object, which is not limited in the present invention. The monitoring device 20 may be an image capturing device and/or a motion sensing device, or an electronic device combined with other devices, such as a combination of a motion sensing device and an illumination device, depending on the different functions performed, which is not limited in the present invention. In the present embodiment, the monitoring device 20 includes a housing 21 and a wire 22, and the wire 22 is connected to the housing 21. For example, if the monitoring device 20 is an image capturing device, the housing 21 is the housing 21 of the image capturing device, and electronic elements (not shown) such as a lens module, a light source module, etc., such as a circuit Board (PCB), are disposed in the housing 21. The wires 22 are the wires 22 connected to the circuit board, and they pass through the housing 21, so the wires 22 are connected to the housing 21.

In the present embodiment, the mounting base 10 includes a base 11, a first bushing 12, a second bushing 13, and a fixing member 14. The base 11 includes a ball axle 111, a first wire receiving portion 112, and a mounting seat 113. The ball axle 111 extends upward from the surface of the mounting seat 113, i.e. extends upward perpendicular to the mounting seat 113, and the mounting seat 113 may have a hollow structure. The first wire receiving portion 112 is located inside the ball axle 111 and can communicate with the hollow structure inside the mounting seat 113. In addition, the mounting base 113 may also be provided with a circuit board and electrically connected to the wire 22.

Fig. 3 is a schematic view of the fixing member and the first sleeve of fig. 2 disposed outside the ball axle, please refer to fig. 2 and fig. 3. In the present embodiment, the fixing member 14 includes an internal thread 141, and a first opening 142 and a second opening 143 opposite to each other. The fixing member 14 is a hollow cylindrical structure, the internal thread 141 is located on the inner wall of the fixing member 14, and the openings at the upper and lower sides are referred to as a second opening 143 and a first opening 142, respectively. In the perspective of fig. 2 and 3, the first opening 142 is located at the lower side of the fixing member 14, and the second opening 143 is located at the upper side of the fixing member 14. When assembling the mounting base 10, the first opening 142 of the fixing member 14 may be aligned with the ball axle 111 and pass through the ball axle 111, so that the fixing member 14 is directly disposed on the mounting base 113 and outside the ball axle 111.

Next, the first sleeve 12 is placed outside the ball axle 111. As shown in fig. 2, the first hub 12 of the present embodiment includes a side opening 121. After the first sleeve 12 is sleeved outside the ball axle 111 through the side opening 121, the first sleeve 12 can move downward along the ball axle 111 to the mounting seat 113 and is located inside the fixing element 14. It should be noted that, from the perspective of fig. 2 and 3, the mounting base 10 of the present embodiment is assembled by first assembling the lower half and the upper half, respectively, and then combining the lower half and the upper half. The housing 21 of the monitoring device 20, the fixing member 14 and the first sleeve 12 are assembled to the base 11, which is the lower assembly component. The following description of the components for assembling the upper half may first mount the housing 21 of the monitoring device 20 to the second hub 13. As shown in fig. 3, the second bushing 13 includes a second wire receiving portion 131, an external thread 132, a connecting portion 133, and a second sleeving portion 134. The second wire receiving portion 131 is located inside the second sleeve 13, and the second wire receiving portion 131 is located corresponding to the first wire receiving portion 112.

The external thread 132 and the connecting portion 133 are located outside the second shaft sleeve 13, and the second sleeve portion 134 is located at the bottom end of the second shaft sleeve 13 in the perspective of fig. 2 and 3. The external thread 132 of the present embodiment is disposed adjacent to the connecting portion 133, and the external thread 132 is close to the second nesting portion 134, and the connecting portion 133 is close to the top end of the second sleeve 13. The second wire receiving portion 131 penetrates the second bushing 13, such that an opening of one end of the second wire receiving portion 131 is located at the connecting portion 133, and an opening of the other end is located at the second nesting portion 134.

Moreover, the housing 21 of the monitoring device 20 includes a receiving groove 211, and the wire 22 passes through the receiving groove 211. The receiving cavity 211 of the present embodiment corresponds to the connecting portion 133 of the second shaft sleeve 13, so that the receiving cavity 211 can be sleeved and connected to the connecting portion 133. Specifically, the operator can first place the wires 22 in the second wire receiving portion 131 and then sleeve the receiving groove 211 to the outside of the connecting portion 133. Next, the housing 21 is locked to the connecting portion 133 of the second bushing 13 by the screw 212, and at this time, the wire 22 is received in the second wire receiving portion 131.

In other embodiments, the housing 21 may be connected to the connecting portion 133 in other manners, such as but not limited to, snap, buckle, or adhesive. In addition, an internal thread may be formed inside the receiving groove 211, and an external thread may be formed outside the connecting portion 133, so that the housing 21 is locked to the second sleeve 13 by the way that the internal thread of the receiving groove 211 and the external thread of the connecting portion 133 are matched with each other.

Preferably, the second shaft sleeve 13 further includes a first waterproof member 135 sleeved outside the connecting portion 133. The first waterproof member 135 is an elastic O-ring (O-ring), which may be made of a material having a waterproof effect, such as but not limited to rubber or silicone. When the receiving groove 211 of the housing 21 is connected to the connecting portion 133 of the second bushing 13, the surface of the first waterproof member 135 can contact and interfere with the receiving groove 211 of the housing 21, so as to prevent water vapor from entering the interior of the housing 21 from the gap between the receiving groove 211 and the connecting portion 133.

Preferably, the mounting base 10 further includes a second waterproof member 15, which is a cover made of rubber or silicone. The second waterproof member 15 has a hollow structure and is sleeved on the outer side of the wire 22. Specifically, before the housing 21 is mounted to the second bushing 13, the wire 22 may be first inserted through the hollow structure of the second waterproof member 15. Then, the second waterproof member 15 and the wires 22 are accommodated in the second wire accommodating portion 131, and at this time, the accommodating groove 211 of the housing 21 is also sleeved to the outside of the connecting portion 133. The second waterproof member 15 is accommodated in the second wire accommodating portion 131 at the opening of the connecting portion 133, and the surface of the second waterproof member 15 contacts and interferes with the accommodating groove 211 of the housing 21, so as to prevent moisture from entering the housing 21 from the second wire accommodating portion 131, and further prevent the moisture from damaging the circuit board disposed in the housing 21. In addition, the cushioning material of the second waterproof member 15 can prevent the wires 22 in the second wire housing portion 131 from being worn and broken due to the long-term rotation of the housing 21.

It should be noted that there is no priority in assembling the components of the lower and upper halves. The foregoing is an example of first assembling the lower half components, and in other embodiments, the upper half components may also be assembled first, and the invention is not limited thereto.

Fig. 4 is a schematic view of the second sleeve of fig. 3 assembled to the ball axle, please refer to fig. 4. One end of the wire 22 is exposed from the second wire receiving portion 131 through the opening of the second nesting portion 134, so the wire 22 can be first placed in the first wire receiving portion 112 of the base 11. Then, the second sleeve 13 and the housing 21 are moved downward, and the second engaging portion 134 is engaged with the outer side of the ball axle 111. The second nesting portion 134 of the present embodiment has an arc-shaped inner wall and is engaged with the spherical surface of the ball axle 111, so that the second nesting portion 134 can be nested outside the ball axle 111. At this time, the second wire receiving portion 131 and the first wire receiving portion 112 are communicated with each other, and the wires 22 are simultaneously received in the second wire receiving portion 131 and the first wire receiving portion 112.

Preferably, the base 11 further includes a third hook 114, and the third hook 114 is located on an inner wall of the first wire receiving portion 112. Correspondingly, the wire 22 has a fourth hook 221 located outside the wire 22. The third hook 114 protrudes from the inner wall of the first wire accommodating portion 112, and the closer to the mounting seat 113, the more the third hook 114 protrudes from the inner wall of the first wire accommodating portion 112. In the view of fig. 4, the fourth hook 221 is a hook-shaped structure tapering downward. When the wire 22 is placed in the first wire receiving portion 112, the fourth hook 221 is guided to move under the third hook 114, and then the third hook 114 and the fourth hook 221 are engaged with each other. If the second sleeve 13 moves upward, the fourth hook 221 may be limited by the third hook 114, so as to prevent the second sleeve 13 from separating from the ball axle 111, which is more beneficial to subsequent assembly.

Preferably, the base 11 further includes a third waterproof member 16, which is accommodated in the first wire accommodating portion 112 and covers the outer side of the wire 22. In this embodiment, the third moisture-proof member 16 is located at the opening of the first wire receiving portion 112 close to the mounting seat 113, so as to prevent moisture from entering the mounting seat 113 from the first wire receiving portion 112, and further prevent the circuit board mounted on the mounting seat 113 from being damaged by the moisture. In detail, after the wires 22 are placed in the first wire-receiving portion 112, preferably after the mounting base 10 is assembled, a waterproof adhesive may be poured into the first wire-receiving portion 112 on the bottom surface of the mounting base 113, and after the waterproof adhesive is cured, the third waterproof member 16 of the embodiment is formed. In other embodiments, the third waterproof member 16 may also be a cover structure made of waterproof material, so as to be directly plugged into the first wire receiving portion 112, which is not limited in the disclosure.

Fig. 5 is a schematic view of the first sleeve and the fixing member shown in fig. 3 assembled to the ball axle, please refer to fig. 2 and 5. The first sleeve 12 of the present embodiment further includes a first engaging portion 122 and a protruding portion 123, the first engaging portion 122 also has an arc inner wall and cooperates with the spherical surface of the ball axle 111, so that the first engaging portion 122 can be engaged with the outer side of the ball axle 111. In the present embodiment, the end of the first nesting portion 122 having the largest inner diameter is referred to as the tip. The protrusion 123 extends outward from the top end of the first engaging portion 122, i.e., extends outward from the first engaging portion 122.

In this embodiment, the inner diameter of the first opening 142 of the fixing member 14 is smaller than the outer diameter of the convex portion 123 of the first sleeve 12. When the first sleeve 12 is sleeved on the ball axle 111 through the side opening 121, the top end is directed upward. Next, when the operator moves the fixing element 14 from the mounting seat 113 to the direction of the ball axle 111, that is, when the fixing element 14 moves upward, the first sleeve 12 can also be driven to move to the direction of the ball axle 111 because the inner diameter of the first opening 142 is smaller than the outer diameter of the protrusion 123. At this time, the protrusion 123 and the tip of the first engaging portion 122 are located inside the first opening 142, and the other portion of the first engaging portion 122 is exposed from the first opening 142. In other words, in the embodiment, one end of the fixing element 14 is connected to the outer side of the first shaft sleeve 12 by the design of the first opening 142 and the protrusion 123, in other embodiments, the fixing element 14 and the first shaft sleeve 12 may be connected by other manners, for example, by using other fastening structures, and the invention is not limited thereto.

After the first shaft sleeve 12 is driven by the fixing element 14 to move toward the ball axle 111, the first engaging portion 122 of the first shaft sleeve 12 is engaged with the outer side of the ball axle 111. Fig. 6 is a schematic view of the first sleeve and the fixing element shown in fig. 5 from another perspective, please refer to fig. 2, fig. 5 and fig. 6, preferably, the first sleeve 12 includes a first hook 124, and the first hook 124 is formed by extending upward from the top end of the first sleeve portion 122. Correspondingly, the second sleeve 13 includes a second hook 136, and the second hook 136 is located at the bottom end of the second sleeving portion 134. When the first engaging portion 122 of the first sleeve 12 is engaged with the outer side of the ball axle 111, the first hook 124 corresponds to the second hook 136, so that the first hook 124 and the second hook 136 are engaged with each other. The relative positions of the first shaft sleeve 12 and the second shaft sleeve 13 are preliminarily fixed by the first hook 124 and the second hook 136.

When the fixing member 14 is moved from the mounting seat 113 to the direction of the ball axle 111 and moved to the outside of the second sleeve 13, the internal thread 141 of the fixing member 14 is matched with the external thread 132 of the second sleeve 13, and the fixing member 14 is locked to the second sleeve 13 by rotating the fixing member 14. In other words, the fixing member 14 of the present embodiment is connected to the second sleeve 13 in a screw-locking manner. At this time, the first bushing 12 is located at the first opening 142 of the fixing member 14, and the second bushing 13 is located at the second opening 143 of the fixing member 14. In addition to fixing the relative position of the first sleeve 12 and the second sleeve 13 again, the first sleeve 12 and the second sleeve 13 can be pressed tightly, so that the first nesting portion 122 and the second nesting portion 134 are more tightly attached to the ball axle 111.

In other embodiments, when the fixing member 14 rotates and releases from the second sleeve 13, the first hook 124 and the second hook 136 are still engaged continuously to maintain the waterproof property of the mounting base 10.

When the housing 21 of the monitoring device 20 rotates, the second sleeve 13 is driven to rotate relative to the ball axle 111, and the fixing member 14 and the first sleeve 12 also rotate together with the second sleeve 13. In order to limit the rotation angle of the housing 21, it is preferable that the base 11 includes a limiting groove 115 (as shown in fig. 2), and the second sleeve 13 includes a limiting portion 137 (as shown in fig. 7), and fig. 7 is a schematic view of another view angle of the second sleeve shown in fig. 2. The limiting groove 115 is located outside the ball axle 111, i.e. the limiting groove 115 is formed on the surface of the ball axle 111. Fig. 8A is a schematic view of the housing, the second shaft sleeve and the base shown in fig. 2, and the housing shown in fig. 8A swings upward, please refer to fig. 7 and 8A at the same time. The limiting portion 137 is disposed at the inner side of the second nesting portion 134, and when the second nesting portion 134 is nested at the outer side of the ball axle 111, the limiting portion 137 is located in the limiting groove 115.

When the housing 21 drives the second shaft sleeve 13 to rotate, the limiting portion 137 also moves in the limiting groove 115. If the swing amplitude of the housing 21 is too large, the limit groove 115 can be abutted against the limit portion 137 to limit the swing angle of the housing 21. Fig. 8B is a cross-sectional view of line a-a shown in fig. 8A, please refer to fig. 8A and 8B. When the limiting part 137 contacts with the top end of the limiting groove 115, the second sleeve 13 is limited, and the housing 21 is limited to swing upwards. Fig. 9 is a schematic cross-sectional view of the housing, the second shaft sleeve, the fixing member and the base shown in fig. 2, and the housing shown in fig. 9 swings downward. When the limiting part 137 contacts with the bottom end of the limiting groove 115, the casing 21 is limited to swing downwards. Fig. 10A is a schematic view of the housing, the second shaft sleeve and the base shown in fig. 2, fig. 10B is a schematic cross-sectional view taken along line a-a shown in fig. 10A, and the housing 21 shown in fig. 10A and 10B swings to the right. In the view shown in fig. 10A and 10B, when the limiting portion 137 and the right inner wall of the limiting groove 115 contact each other, the housing 21 is limited to swing to the right. Similarly, when the limiting portion 137 contacts the left inner wall of the limiting groove 115, the housing 21 is limited to swing left. In addition, the stopper 137 of the second sleeve 13 and the stopper groove 115 of the base 11 can restrict the vertical and horizontal swing angles of the housing 21, and also restrict the swing of the wire 22 in the first wire housing portion 112, thereby preventing the wear and breakage of the wire 22 due to the long-term rotation of the housing 21.

In summary, according to the monitoring system and the mounting base thereof of the present invention, the mounting base includes a base, a first shaft sleeve, a second shaft sleeve and a fixing member, the first shaft sleeve and the second shaft sleeve are respectively sleeved outside the ball shaft of the base, and an end of the fixing member is connected to the first shaft sleeve.
