Description

Environment monitoring device

Technical Field

The present invention relates to an environment monitoring apparatus.

Background

With the increasing importance of the quality and safety of the living environment, the concern about whether the surrounding environment has a public security dead angle is increased. At present, the security blind spots in public or private places are reduced by the aid of environmental monitoring devices, such as image capturing devices and/or motion sensing devices. Specifically, whether outdoors or indoors, such as parking lots, department stores, financial business buildings, etc., image capturing devices (monitors) and/or motion sensing devices are disposed in different spaces to simultaneously monitor a plurality of areas. For example, the image capturing device can directly monitor images of the space, the motion sensing device can be connected with an anti-theft system or a lighting system, and when people or other animals are sensed, the motion sensing device can give out warning or turn on lighting equipment, and can also be used for environmental monitoring. Therefore, in the present specification, an image capturing device, a motion sensing device, or other sensing devices capable of performing an environmental monitoring function are generally referred to as an environmental monitoring device.

However, no matter the image capturing device or the motion sensing device is installed in the outdoor or indoor space, or the driving recorder is installed on the automobile or the motorcycle, the range of the image captured by the lens and the angle of view, or the sensing range detected by the motion sensing device, are greatly limited. At present, although the environmental monitoring device is used in combination with other auxiliary mechanisms, the image range or sensing range is increased by small rotation. However, the auxiliary mechanism must rotate simultaneously with the environmental monitoring device, so that the environmental monitoring device is limited by the circuit, and the angle of the environmental monitoring device is still limited to 70-110 degrees, and the whole image of the environmental space cannot be recorded.

Therefore, it is an important subject to provide an environment monitoring device that can obtain a wide environment monitoring range without being limited by the angle.

The driving module is connected with the rotating body and drives the rotating body to rotate along a clockwise direction and rotate along a counterclockwise direction. The environment monitoring module is arranged on the rotating body.

With the above structure, when the rotating body rotates, the first limiting member and the second limiting member are separated.

Detailed Description

The following detailed description of the embodiments of the present invention with reference to the drawings and specific examples is provided for further understanding the objects, aspects and effects of the present invention, but not for limiting the scope of the appended claims.

Please refer to fig. 1, fig. 2 and fig. 3. FIG. 1 is a schematic view of one embodiment of an environmental monitoring apparatus of the present invention; FIG. 2 is an exploded schematic view illustrating the environmental monitoring apparatus shown in FIG. 1; fig. 3 is a schematic sectional view showing a line a-a shown in fig. 1.

It should be noted that the environmental monitoring device D of the present embodiment includes an image capturing device, a motion sensing device, or other sensing devices for monitoring an environmental space, or a combination thereof, and the invention is not limited thereto. As shown in fig. 1 and fig. 2, in an embodiment of the present invention, an environment monitoring apparatus D of the present invention includes a base 1, a rotating body 2, a driving module 3 and an environment monitoring module 4, wherein a portion of the driving module 3 is shown in fig. 3. According to the different functions of the environment monitoring device D, such as image capturing, object sensing, or a combination thereof, the environment monitoring module 4 can be an image capturing module and/or a motion sensing module, and the environment monitoring module 4 of the following embodiments and drawings includes an image capturing module 41 and a motion sensing module 42, so as to capture the peripheral image of the moving object. That is, the environment monitoring module 4 of the present embodiment is described as a combination of the image capturing module 41 and the motion sensing module 42. Of course, in other embodiments, the environment monitoring module 4 may be only the image capturing module 41, the motion sensing module 42, or other sensing modules capable of detecting an object, and the invention is not limited thereto.

Referring to fig. 1 and fig. 2, the rotator 2 is engaged with the base 1, and the engaging structure is further described later, but the base 1 of the present embodiment is a cylindrical structure, the rotator 2 is disposed at the opening of the base 1, and at least part of the rotator 2 is accommodated in the base 1, as shown in fig. 2. The environmental monitoring module 4 is disposed on the rotating body 2, and a lens portion of the image capturing module 41 of the environmental monitoring module 4 is exposed from an outer surface of the rotating body 2 to obtain an environmental image.

In the present embodiment, the base 1 includes at least one first limiting member 11, and the rotating body 2 includes at least one second limiting member 21 corresponding to the first limiting member 11. Specifically, the base 1 of the present embodiment includes a first limiting member 11, a fixing member 12 and a bearing 13, wherein the fixing member 12 is disposed at an opening of the base 1 and further used for bearing the rotating body 2. Preferably, the first limiting member 11 of the present embodiment is disposed on the inner surface of the fixing member 12. Correspondingly, the second position-limiting member 21 is disposed on the outer surface of the rotating body 2 and is adjacent to the bottom edge of the rotating body 2. Therefore, when the rotating body 2 is disposed in the base 1 and is carried by the fixing member 12, and the rotating body 2 rotates to a predetermined position, it should be noted that the predetermined position refers to a position where the first limiting member 11 and the second limiting member 21 contact each other. That is, the side surface of the second limiting member 21 and the side surface of the first limiting member 11 can contact each other, and the details thereof will be further described later. Of course, in other embodiments, the rotating body 2 may be directly disposed on the base 1 without being supported by the fixing member 12, and at this time, the first limiting member 11 may also be directly disposed on the sidewall of the rotating body 2, which can achieve the same effect, and the invention is not limited thereto.

In the present embodiment, the first stopper 11 and the second stopper 21 are both convex portions, but the present invention is not limited to the shape, and may be a circular convex portion, a square convex portion, or other polygonal convex portions. The thickness of the protruding portion only needs to be able to be accommodated in the gap between the rotating body 2 and the fixing member 12, and the first limiting member 11 and the second limiting member 21 can be contacted with each other when they rotate to a predetermined position.

Referring to fig. 3, the rotator 2 of the present embodiment further includes a rotating shaft 22, and the rotating shaft 22 is disposed in the bearing 13 and further connected to the base 1, that is, the rotator 2 is connected to the base 1 through the rotating shaft 22. In addition, the driving module 3 is connected to the rotating body 2, and in detail, the driving module 3 of the present embodiment is disposed at the bottom of the base 1 and connected to the rotating shaft 22, so that the driving module 3 can drive the rotating shaft 22 to rotate in the horizontal direction. That is, the rotating body 2 is driven to rotate clockwise C1 and counterclockwise C2, so that the first position-limiting member 11 and the second position-limiting member 21 have a contacting state S1 and a separating state S2, as shown in fig. 4 and 5.

Fig. 4 is a cross-sectional view of the line B-B shown in fig. 3, which is also a schematic view of the first limiting member 11 and the second limiting member 21 in the separated state S2; fig. 5 is a schematic diagram showing the rotating body shown in fig. 4 after being driven to rotate, and is also a schematic diagram showing the first limiting member 11 and the second limiting member 21 in a contact state S1.

Here, the case where the rotor 2 is driven by the driving module 3 to rotate in the clockwise direction C1 will be described as an example. When the rotating body 2 rotates, the second limiting member 21 is driven to generate displacement, and most of the situations are as shown in fig. 4, the first limiting member 11 and the second limiting member 21 are in a separated state S2, that is, the first limiting member 11 and the second limiting member 21 are not in contact with each other. When the rotating body 2 continuously rotates clockwise C1, the second position-limiting member 21 gets closer to the first position-limiting member 11 (which is a fixed position) until the first position-limiting member 11 and the second position-limiting member 21 are in a contact state S1, as shown in fig. 5. When the first limiting member 11 and the second limiting member 21 contact each other, the driving module 3 drives the rotating shaft 22 to rotate C2 in the counterclockwise direction, and the state shown in fig. 4 can be returned to. On the contrary, if the driving module 3 drives the rotating shaft 22 to rotate in the counterclockwise direction C2 first, when the first limiting member 11 and the second limiting member 21 contact each other, the driving module 3 drives the rotating shaft 22 to rotate in the clockwise direction C1. In short, when the second stopper 21 rotates to make the first stopper 11 and the second stopper 21 in the contact state S1, the driving module 3 performs switching between clockwise rotation C1 and counterclockwise rotation C2.

In the present embodiment, the driving module 3 includes a circuit board 31, which is also disposed inside the base 1, and the driving module 3 further includes a pressure sensor 32 for sensing the contact state S1 of the first limiting member 11 and the second limiting member 21. The invention is not limited to the position of the pressure sensor 32, and it can be disposed on the circuit board 31 to share the circuit. When the first limiting member 11 and the second limiting member 21 are in the contact state S1, the pressure sensor 32 can receive the resistance signal. When the driving module 3 receives the resistance signal, the rotating body 2 can be driven to switch between clockwise rotation C1 and counterclockwise rotation C2. The pressure sensor 32 may be a piezo-resistive sensor or other type of pressure sensor, but the invention is not limited thereto, and the pressure sensor is well known in the art, and therefore will not be described herein.

Since the environment monitoring module 4 is disposed on the rotating body 2, the driving module 3 can drive the rotating body 2 and the environment monitoring module 4 to rotate simultaneously, so that the image capturing module 41 captures a whole image of 360 degrees substantially, and the motion sensing module 42 can monitor a whole environment space of 360 degrees substantially. Moreover, the corresponding arrangement of the first limiting member 11 and the second limiting member 21 in the present embodiment further enables the rotating body 2 to rotate C1 clockwise, for example, and then the first limiting member 11 and the second limiting member 21 contact each other to switch to rotate C2 counterclockwise, thereby avoiding the problem of winding the circuit of the environmental monitoring module 4 caused by continuous rotation in the same direction.

As shown in fig. 2, the environmental monitoring module 4 of the present embodiment is disposed on the rotating body 2 and has a sampling axis X1, and the image capturing module 41 is taken as an example for illustration in the present embodiment. In the embodiment, the rotating body 2 includes a top portion 23, the environmental monitoring module 4 is disposed on the top portion 23, and the sampling axis X1 is an axis formed by the lens of the image capturing module 41 disposed perpendicular to the top portion 23. Similarly, the sampling axis (not shown) of the motion sensor module 42 refers to the axis formed by the motion sensor module 42 perpendicular to the top 23.

Preferably, the sampling axis direction X1 is non-parallel to the rotation axis direction X2 of the rotation shaft 22, which can be achieved by the environment monitoring module 4 having a slope or the top 23 being non-planar. In detail, the top 23 of the present embodiment is a non-planar and inclined structure, so that when the environment monitoring module 4 is disposed on the top 23, the sampling axis direction X1 and the rotation axis direction X2 of the rotation shaft 22 are non-parallel. In other embodiments, the top 23 may be curved, which can achieve the same effect.

The environment monitoring module 4 is disposed on the top 23, and the lens of the image capturing module 41 is exposed from the outer surface of the top 23, so as to capture the image of the surrounding environment. The sampling axis X1 and the rotation axis X2 of the rotation axis 22 are not parallel, i.e. the inclined plane design, so as to prevent the image capturing module 41 from shielding the captured image, thereby preventing the occurrence of image dead angles. The motion sensing module 42 is also disposed in an inclined manner, so as to prevent dead angles in the sensed region.

Preferably, as shown in fig. 2, the rotating shaft 22 of the present embodiment has a plurality of ribs 221 sequentially arranged on the surface of the rotating shaft 22, specifically, the long axis direction of the ribs 221 is the same as the long axis direction of the rotating shaft 22, and the ribs 221 are sequentially arranged along the outer surface of the rotating shaft 22, so that the strength of the rotating shaft 22 is increased by the arrangement of the ribs 221, and the durability of the rotating shaft 22 is improved.

Fig. 6 is an exploded schematic view of another embodiment of the environmental monitoring apparatus of the present invention, in the present embodiment, the base 1 further includes a connecting element 14, one end of the connecting element 14 is connected to the driving module 3, that is, is accommodated in the bearing 13 and connected to the driving module 3, and details thereof can refer to the embodiment shown in fig. 3, which is not repeated herein. The other end of the connecting member 14 is connected to the rotating shaft 22, and the connecting member 14 has a plurality of concave portions 141 corresponding to the rib portions 221 of the rotating shaft 22, so that at least a portion of the rib portions 221 are received in the concave portions 141.

In addition, the present invention does not limit the shapes of the first limiting members 11 and the second limiting members 21, and does not limit the number of the first limiting members 11 and the second limiting members 21, and the rotation range of the rotator 2 can be adjusted by disposing a plurality of first limiting members 11 or a plurality of second limiting members 21, so as to adjust the range of capturing the image. For example, fig. 7 is a schematic cross-sectional view of another embodiment of the environmental monitoring apparatus of the present invention, as shown in fig. 7, a base 1 of the present embodiment has two first limiting

members

11a and 11b, and like the previous embodiments, the base 1 of the present embodiment also includes a fixing member 12, and the first limiting

members

11a and 11b are disposed on an inner surface of the fixing member 12. The rotating body 2 has a second limiting member 21, so that when the rotating body 2 rotates, the second limiting member 21 can move between the two first limiting

members

11a and 11 b. That is, after the second stopper 21 rotates C1 clockwise to contact the first stopper 11b, it rotates C2 counterclockwise in reverse to contact the first stopper 11 b. For the switching between the clockwise rotation C1 and the counterclockwise rotation C2, reference is made to the foregoing embodiments, which are not repeated herein. The two first position-limiting

members

11a and 11b of the present embodiment are separated by 180 degrees, so that the rotation range of the rotating body 2 can be limited to 180 degrees, and the manufacturer of the environment monitoring device D can adjust the position according to the requirement. In addition, in other embodiments, the design that the rotating body has two second position-limiting members may also be used, so that when the rotating body rotates, the two second position-limiting members respectively contact with the first position-limiting members, and the same effect may also be achieved, which is not limited by the present invention.

Fig. 8 is a schematic cross-sectional view of an environment monitoring apparatus according to another embodiment of the present invention, please refer to fig. 8. In addition, the present invention does not limit the arrangement positions of the first limiting member 11c and the second limiting member 21c, but only needs to correspond to each other, so that the rotating bodies 2 can contact each other when rotating. For example, the first position-limiting member 11c can be disposed on the bearing 13 of the base 1, and at this time, the second position-limiting member 21c can be disposed on the rotating shaft 22 of the rotating body 2. It should be noted that the first limiting member 11c and the second limiting member 21c shown in fig. 8 are in the separated state S2 when rotating, and when the driving module 3 drives the rotating body 2 and the rotating shaft 22 to rotate to the predetermined position, the first limiting member 11c and the second limiting member 21c can contact each other, and the driving module 3 further drives the rotating shaft 22 to rotate in the opposite direction. The operation details can refer to the foregoing embodiments, and are not repeated herein.

As can be seen from the foregoing description, the environmental monitoring apparatus of the present invention includes a base, a rotating body, a driving module and an environmental monitoring module, wherein the environmental monitoring module is disposed on the rotating body, and the driving module drives the rotating body to rotate, so that the environmental monitoring module disposed on the rotating body can obtain a larger image range or sensing range. Moreover, by means of the structural design that the base comprises the first limiting part and the rotating body comprises the second limiting part corresponding to the first limiting part, when the first limiting part and the second limiting part are in a contact state due to the rotation of the second limiting part, the driving module performs switching between clockwise rotation and counterclockwise rotation, and the problem of line winding of the environment monitoring module caused by continuous rotation in the same direction can be avoided.

The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
