[0002] With the continuous advancement of science and technology, the functions of smart lighting devices have been significantly improved in many aspects. These devices are no longer limited to basic lighting purposes, but are widely used in various intelligent systems, such as smart home systems, smart parking systems, smart factories and other types of smart applications, showing great application potential and flexibility. However, there are still many problems in the actual use of existing smart lighting devices that need to be improved.

[0003] For example, the sensing module of existing intelligent lighting devices often lacks an effective rotating structure design, resulting in a fixed sensing direction that cannot be flexibly adjusted according to actual needs. Since the sensing module cannot rotate, the sensing range of the sensing module is fixed, which limits its applicability in different scenarios. Therefore, the existing intelligent lighting devices are subject to many restrictions in application and cannot meet the ever-changing actual needs. Summary of the invention

[0004] According to one embodiment of the present invention, a rotatable sensing module is provided, which includes a rotating seat, an outer shell, a circuit board, a sensor and two rotating parts. The rotating seat includes a first side wall, a second side wall, two connecting parts and two fixing grooves. The first side wall is connected to the second side wall through the two connecting parts. A first space is formed between the first side wall and the second side wall. The two fixing grooves are respectively arranged on the inner surfaces of the first side wall and the second side wall. The outer shell has two rotating holes, which are respectively arranged on both sides of the outer shell. A part of the outer shell is arranged in the first space. The circuit board is arranged in the outer shell. The sensor is electrically connected to the circuit board. The two rotating parts are respectively arranged in the two rotating holes, and each rotating part has a buckle on one side. The buckle of one rotating part is fixed to the fixing groove of the first side wall, and the buckle of the other rotating part is fixed to the fixing groove of the second side wall. Each buckle includes an arc portion and a U-shaped portion connected to each other.

[0005] In one embodiment, the arc portion is a major arc.

[0006] In one embodiment, the arc portion is a minor arc.

[0007] In one embodiment, each buckle is hollow.

[0008] In one embodiment, each fixing slot includes two fixing portions that are symmetrical to each other. Each fixing portion includes a curved portion and a straight portion that are connected to each other.

[0009] In one embodiment, each fixing groove further includes a positioning portion, and the positioning portion is disposed in the fixing groove.

[0010] In one embodiment, the U-shaped portion has an inclined surface.

[0011] In one embodiment, a second space is formed between the first side wall, the second side wall and the two connecting parts, and the sensor faces the second space.

[0012] In one embodiment, the edge of each rotating hole has a plurality of teeth.

[0013] In one embodiment, each rotating member has a gear portion on the other side.

[0014] As described above, the rotatable sensing module according to the embodiments of the present invention may have one or more of the following advantages:

[0015] (1) In one embodiment of the present invention, a rotatable sensing module comprises a rotating seat, an outer shell, a circuit board, a sensor and two rotating members. The rotating seat comprises a first side wall, a second side wall, two connecting parts and two fixing grooves. The first side wall is connected to the second side wall through the two connecting parts. A first space is formed between the first side wall and the second side wall. The two fixing grooves are respectively arranged on the inner surfaces of the first side wall and the second side wall. The outer shell has two rotating holes, which are respectively arranged on both sides of the outer shell. A part of the outer shell is arranged in the first space. The circuit board is arranged in the outer shell. The sensor is electrically connected to the circuit board. The two rotating members are respectively arranged in the two rotating holes, and one side of each rotating member has a buckle. The buckle of one rotating member is fixed to the fixing groove of the first side wall, and the buckle of the other rotating member is fixed to the fixing groove of the second side wall. Each buckle comprises an arc portion and a U-shaped portion connected to each other. The above-mentioned rotatable structure can realize the rotation function, so the sensing range of the rotatable sensing module is adjustable, so it can meet the needs of different applications.

[0016] (2) In one embodiment of the present invention, each buckle includes an arc-shaped portion and a U-shaped portion connected to each other, so that the buckle is in a petal shape. The structural design of the U-shaped portion of the petal-shaped buckle makes it easy to install the buckle in the corresponding fixing groove. In addition, the combination of the arc-shaped portion and the U-shaped portion can effectively prevent the buckle and the rotating seat from generating relative offset. Therefore, the combined structure of the two buckles and the rotating seat can achieve high structural stability, effectively improving the overall structural strength of the rotatable sensing module.

[0017] (3) In one embodiment of the present invention, each fixing groove further includes a positioning portion, and the positioning portion is disposed in the fixing groove. The U-shaped portion of each buckle has an inclined surface, so that the positioning portion can enter the internal space of the corresponding buckle through the inclined surface. In this way, the positioning portion can be embedded in the corresponding buckle, so that the buckle can be more stably embedded in the corresponding fixing groove. This structural design further improves the structural stability of the combined structure of the above-mentioned two buckles and the rotating seat. Therefore, the overall structural strength of the rotatable sensing module can also be further improved.

[0018] (4) In one embodiment of the present invention, each side of the outer shell may have two limit protrusions. In addition, each rotating member may also have a protrusion, which is arranged on the outer edge of the rotating member. The structural design of the two limit protrusions can limit the movement range of the protrusion, so the rotation angle of the rotating seat can be limited to an ideal range.

[0019] (5) In one embodiment of the present invention, the rotatable structure of the rotatable sensing module can realize the rotation function, so the sensing range of the rotatable sensing module is adjustable. Therefore, the rotatable sensing module can be applied to various intelligent systems, such as smart home systems, smart parking systems, smart factories, etc. Therefore, the application of the rotatable sensing module can be more extensive and can meet the trend of future development.

[0020] (6) In one embodiment of the present invention, the rotatable structure of the rotatable sensing module can more effectively implement the sensing function to detect moving objects, so that various intelligent lighting devices can provide lighting functions more effectively. Therefore, the rotatable sensing module can meet the needs of different applications and is more flexible in use. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 2 FIG. 4 is a diagram showing an assembly of a rotatable sensing module according to a first embodiment of the present invention. Figure 3It is a stereoscopic view of the outer shell of the rotatable sensing module of the first embodiment of the present invention. As shown in the figure, the rotatable sensing module 1 includes a rotating seat 11, an outer shell 12, a circuit board 13, a sensor 14 and two rotating parts 15. The figure also shows a lamp tube 2, which includes an end cover 22 and a lampshade 21. The rotatable sensing module 1 can be set on the end cover 22 of the lamp tube 2. A controller 221 can be set in the end cover 22, such as a microcontroller (MCU), a central processing unit (CPU), an application-specific integrated circuit chip (ASIC), a field programmable gate array (FPGA) or other similar components. This embodiment is only for example and not for limitation. The rotatable sensing module 1 can be applied to various devices (such as doors, windows, fans, air conditioners, various electronic devices or various electrical appliances), and is not limited to the lamp tube 2.

[0036] The rotating base 11 includes a first side wall 111, a second side wall 112, two connecting parts 113 and two fixing grooves 114. The first side wall 111 is connected to the second side wall 112 through the two connecting parts 113. A first space S1 is formed between the first side wall 111 and the second side wall 112. A second space S2 is formed between the first side wall 111, the second side wall 112 and the two connecting parts 113. The two fixing grooves 114 are respectively disposed on the inner surfaces of the first side wall 111 and the second side wall 112. The rotating base 11 can be made of metal or plastic.

[0037] The outer shell 12 has two rotation holes RH, which are respectively arranged on both sides of the outer shell 12. The edge of each rotation hole RH has a plurality of tooth-shaped portions TP. A portion of the outer shell 12 is arranged in the first space S1. The outer shell 12 may include two half shells 121, which may be combined with each other. The outer shell 12 may be made of metal or plastic. Each side of the two sides of the outer shell 12 may have two limit protrusions LB.

[0038] The circuit board 13 is disposed in the outer shell 12 . One end of the circuit board 13 is connected to the end cover 22 to be electrically connected to the controller 221 .

[0039] The sensor 14 may be disposed at the other end of the circuit board 13 and electrically connected to the circuit board 13. The sensor 14 faces the second space S2. In one embodiment, the sensor 14 may be a microwave sensor, an infrared sensor or other similar components. When the sensor 14 detects a moving object (such as a person or a vehicle), the sensor 14 generates a sensing signal, and the controller 221 may control the lamp 2 to turn on or change the brightness or color temperature of the lamp 2 according to the sensing signal.

[0040] The two rotating members 15 are respectively disposed in the two rotating holes RH.

[0041] Of course, this embodiment is only used for illustration and does not limit the scope of the present invention. Equivalent modifications or changes made to the rotatable sensing module 1 according to this embodiment should still be included in the patent scope of the present invention.

[0042] See also Figure 4 , Figure 5 and Figure 6 , and please also refer to Figure 1 to Figure 3 . Figure 4 FIG. 4 is a front view of a rotating member of a rotatable sensing module according to a first embodiment of the present invention. Figure 5 FIG. 4 is a first stereoscopic view of a rotating member of a rotatable sensing module according to a first embodiment of the present invention. Figure 6 This is a second stereoscopic view of the rotating member of the rotatable sensing module of the first embodiment of the present invention. As shown in the figure, each rotating member 15 has a buckle 151 on one side and a gear portion 152 on the other side, which can be mutually engaged with the above-mentioned multiple tooth-shaped portions TP of the corresponding rotating hole RH. In this way, the rotating member 15 can rotate. In addition, each rotating member 15 also includes a protrusion 153, which is arranged on the outer edge of the rotating member 15.

[0043] The buckle 151 of one rotating member 15 is fixed to the fixing groove 114 of the first side wall 111. The buckle 151 of the other rotating member 15 is fixed to the fixing groove 114 of the second side wall 112. In this way, the rotating base 11 can rotate relative to the outer shell 12 to change the direction and sensing range of the sensor 14.

[0044] In addition, as mentioned above, two limiting protrusions LB may be provided on each side of the outer shell 12. The structural design of the two limiting protrusions LB may limit the moving range of the protrusion 153, so that the rotation angle of the rotating seat 11 may be limited to an ideal range.

[0045] Each buckle 151 is hollow and includes an arc-shaped portion 1511 and a U-shaped portion 1512 connected to each other, so that the buckle 151 is in a petal shape or a keyhole shape. The arc-shaped portion 1511 can be a major arc. In another embodiment, the arc-shaped portion 1511 can be a minor arc. In addition, the U-shaped portion 1512 can have a slope SL, which is disposed at the bottom of the U-shaped portion 1512.

[0046] Of course, this embodiment is only used for illustration rather than to limit the scope of the present invention. Equivalent modifications or changes made to the rotatable sensing module 1 according to this embodiment should still be included in the patent scope of the present invention.

[0047] See also Figure 7 , which is a schematic diagram of the fixing slot of the rotatable sensing module of the first embodiment of the present invention, and please also refer to Figure 1 to Figure 6As shown in the figure, the fixing groove 114 disposed on the first side wall 111 includes two fixing portions 1141 symmetrical to each other. Each fixing portion 1141 includes a bending portion BP and a straight portion SP connected to each other. The fixing groove 114 disposed on the second side wall 112 also has the same structure. The above structural design makes the shape of the fixing portion 1141 correspond to the petal-shaped buckle 151.

[0048] Thus, the structural design of the U-shaped portion of the petal-shaped buckle 151 makes it easy to install the buckle 151 in the corresponding fixing groove 114. The combination of the arc portion 1511 and the U-shaped portion 1512 of the buckle 151 can effectively prevent the buckle 151 and the rotating seat 11 from having a relative offset.

[0049] As can be seen from the above, the rotatable sensing module 1 of this embodiment has a rotatable structure. The rotatable structure can realize the rotation function, so the sensing range of the rotatable sensing module 1 is adjustable, so it can meet the needs of different applications.

[0050] In addition, in the present embodiment, each buckle 151 includes an arc-shaped portion 1511 and a U-shaped portion 1512 connected to each other, so that the buckle 151 is in a petal shape. The structural design of the U-shaped portion 1512 of the above-mentioned petal-shaped buckle 151 makes it easy to install the buckle 151 in the corresponding fixing groove 114. In addition, the combination of the arc-shaped portion 1511 and the U-shaped portion 1512 can effectively prevent the buckle 151 and the rotating seat 11 from generating a relative offset. Therefore, the combined structure of the above-mentioned two buckles 151 and the rotating seat 11 can achieve a high structural stability, so that the overall structural strength of the rotatable sensing module 1 is effectively improved.

[0051] In addition, in this embodiment, two limiting protrusions LB may be provided on each of the two sides of the outer shell 12. In addition, each rotating member 15 may also have a protrusion 153, which is provided on the outer edge of the rotating member 15. The structural design of the two limiting protrusions LB can limit the moving range of the protrusion 153, so the rotation angle of the rotating seat 11 can be limited to an ideal range.

[0052] Furthermore, in this embodiment, the rotatable structure of the rotatable sensing module 1 can realize the rotation function, so the sensing range of the rotatable sensing module 1 is adjustable. Therefore, the rotatable sensing module 1 can be applied to various intelligent systems, such as smart home systems, smart parking systems, smart factories, etc. Therefore, the application of the rotatable sensing module can be more extensive and can meet the trend of future development.

[0053] Of course, this embodiment is only used for illustration rather than to limit the scope of the present invention. Equivalent modifications or changes made to the rotatable sensing module 1 according to this embodiment should still be included in the patent scope of the present invention.

[0054] See also Figure 8 , which is a schematic diagram of a fixing slot of a rotatable sensing module according to a second embodiment of the present invention, and please also refer to Figure 1 to Figure 6 As shown in the figure, the fixing groove 114 disposed on the first side wall 111 includes two fixing portions 1141 symmetrical to each other. Different from the above-mentioned embodiment, the fixing groove 114 also includes a positioning portion 1142, and the positioning portion 1142 is disposed in the fixing groove 114. The fixing groove 114 disposed on the second side wall 112 also has the same structure.

[0055] As mentioned above, the U-shaped portion 1512 of each buckle 151 has an inclined surface SL, so that the positioning portion 1142 can enter the internal space of the corresponding buckle 151 through the inclined surface SL. In this way, the positioning portion 1142 can be embedded in the corresponding buckle 151, so that the buckle 151 is more stably embedded in the corresponding fixing groove 114. This structural design further improves the structural stability of the combined structure of the above two buckles 151 and the rotating seat 11. Therefore, the overall structural strength of the rotatable sensing module 1 can also be further improved.

[0056] Of course, this embodiment is only used for illustration rather than to limit the scope of the present invention. Equivalent modifications or changes made to the rotatable sensing module 1 according to this embodiment should still be included in the patent scope of the present invention.

[0057] See also Fig. 9 , which is a first schematic diagram of the use state of the rotatable sensing module of the third embodiment of the present invention. As shown in the figure, the user UR can rotate the rotatable sensing module 1 in the direction of the arrow A1 in the figure (or the opposite direction of the arrow A1), that is, the sensing range of the rotatable sensing module 1 can be adjusted.

[0058] Of course, this embodiment is only used for illustration rather than to limit the scope of the present invention. Equivalent modifications or changes made to the rotatable sensing module 1 according to this embodiment should still be included in the patent scope of the present invention.

[0059] See also Fig.10 , which is a second schematic diagram of the use state of the rotatable sensing module of the third embodiment of the present invention. As shown in the figure, the rotatable sensing module 1 can be installed on the lamp tube 2 in the factory, and the sensing range of different rotatable sensing modules 1 can be appropriately adjusted. In this way, these rotatable sensing modules 1 can all sense the user UR at different positions, so that the lamp tube 2 can be turned on in time.

[0060] The rotatable structure of the rotatable sensing module 1 can realize the rotation function, so the sensing range of the rotatable sensing module 1 is adjustable. Therefore, the rotatable sensing module 1 can be applied to various intelligent systems, such as smart home systems, smart parking systems, smart factories, etc. Therefore, the application of the rotatable sensing module 1 can be more extensive and can meet the trend of future development.

[0061] Of course, this embodiment is only used for illustration rather than to limit the scope of the present invention. Equivalent modifications or changes made to the rotatable sensing module 1 according to this embodiment should still be included in the patent scope of the present invention.

[0062] In summary, according to an embodiment of the present invention, the rotatable sensing module 1 includes a rotating seat 11, an outer shell 12, a circuit board 13, a sensor 14 and two rotating members 15. The rotating seat 11 includes a first side wall 111, a second side wall 112, two connecting parts 113 and two fixing grooves 114. The first side wall 111 is connected to the second side wall 112 through the two connecting parts 113. A first space S1 is formed between the first side wall 111 and the second side wall 112. The two fixing grooves 114 are respectively arranged on the inner surfaces of the first side wall 111 and the second side wall 112. The outer shell 12 has two rotating holes RH, which are respectively arranged on both sides of the outer shell 12. A part of the outer shell 12 is arranged in the first space S1. The circuit board 13 is arranged in the outer shell 12. The sensor 14 is electrically connected to the circuit board 13. The two rotating members 15 are respectively arranged in the two rotating holes RH, and each rotating member 15 has a buckle 151 on one side. The buckle 151 of one rotating member 15 is fixed to the fixing groove 114 of the first side wall 111, and the buckle 151 of the other rotating member 15 is fixed to the fixing groove 114 of the second side wall 112. Each buckle 151 includes an arc portion 1511 and a U-shaped portion 1512 connected to each other. The above-mentioned rotatable structure can realize the rotation function, so the sensing range of the rotatable sensing module 1 is adjustable, so it can meet the needs of different applications.

[0063] According to the embodiment of the present invention, each buckle 151 includes an arc-shaped portion 1511 and a U-shaped portion 1512 connected to each other, so that the buckle 151 is in a petal shape. The structural design of the U-shaped portion of the petal-shaped buckle 151 makes it easy to install the buckle 151 in the corresponding fixing groove 114. In addition, the combination of the arc-shaped portion 1511 and the U-shaped portion 1512 can effectively prevent the buckle 151 and the rotating seat 11 from generating a relative offset. Therefore, the combined structure of the two buckles 151 and the rotating seat 11 can achieve high structural stability, so that the overall structural strength of the rotatable sensing module 1 is effectively improved.

[0064] Furthermore, according to an embodiment of the present invention, each fixing groove 114 further includes a positioning portion 1142, and the positioning portion 1142 is disposed in the fixing groove 114. The U-shaped portion 1512 of each buckle 151 has an inclined surface SL, so that the positioning portion 1142 can enter the internal space of the corresponding buckle 151 through the inclined surface SL. In this way, the positioning portion 1142 can be embedded in the corresponding buckle 151, so that the buckle 151 is more stably embedded in the corresponding fixing groove 114. This structural design further improves the structural stability of the combined structure of the above-mentioned two buckles 151 and the rotating seat 11. Therefore, the overall structural strength of the rotatable sensing module 1 can also be further improved.

[0065] In addition, according to an embodiment of the present invention, two limiting protrusions LB may be provided on each of the two sides of the outer shell 12. In addition, each rotating member 15 may also have a protrusion 153, which is arranged on the outer edge of the rotating member 15. The structural design of the two limiting protrusions LB can limit the moving range of the protrusion 153, so the rotation angle of the rotating seat 11 can be limited to an ideal range.

[0066] In addition, according to the embodiment of the present invention, the rotatable structure of the rotatable sensing module 1 can realize the rotation function, so the sensing range of the rotatable sensing module 1 is adjustable. Therefore, the rotatable sensing module 1 can be applied to various intelligent systems, such as smart home systems, smart parking systems, smart factories, etc. Therefore, the application of the rotatable sensing module 1 can be more extensive and can meet the trend of future development.

[0067] Furthermore, according to the embodiment of the present invention, the rotatable structure of the rotatable sensing module 1 can more effectively realize the sensing function to detect moving objects, so that various intelligent lighting devices can provide lighting functions more effectively.
