Technical Field

[0001] The present invention relates to a sensing module, and particularly to a rotatable sensing module.

Background Art

[0002] With the continuous progress 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 applications, but are widely applied to various smart systems such as smart home systems, smart parking lot systems, smart factories, and other various smart applications, showing extremely high applicability and flexibility. However, conventional smart lighting devices still have many problems that need to be improved in actual use.

[0003] For example, the sensing module of conventional smart lighting devices often lacks an effective rotational structure design, its sensing direction is fixed, and it cannot be flexibly adjusted according to actual needs. Since the sensing module cannot rotate, the sensing range of the sensing module is fixed, and its applicability in different scenes is limited. Therefore, conventional smart lighting devices are subject to many restrictions during application and cannot meet the constantly changing actual needs.

Means for Solving the Problems

[0005] A rotatable sensing module according to one embodiment of the present invention includes a rotating seat, an outer housing, a circuit board, a sensor, and two rotating members. The rotating seat includes a first side wall, a second side wall, two connecting parts, and two fixing grooves. The first side wall connects to the second side wall through the two connecting parts described above. A first space is formed between the first and second side walls. The two fixing grooves described above are provided on the inner surfaces of the first and second side walls, respectively. The outer housing has two rotating holes, each located on either side of the outer housing. A portion of the outer housing is installed in the first space. The circuit board is installed inside the outer housing. The sensor is electrically connected to the circuit board. The two rotating members described above are each installed in the two rotating holes described above and each rotating member has a clip on one side. The clip of one rotating member is fixed to a fixing groove in the first side wall, and the clip of the other rotating member is fixed to a fixing groove in the second side wall. Each clip includes an arc-shaped portion and a U-shaped portion that connect to each other.

[0006] In one embodiment, the arc-shaped portion is a convex arc.

[0007] In one embodiment, the arc-shaped portion is a concave arc.

[0008] In one embodiment, each clip is hollow.

[0009] In one embodiment, each fixing groove includes two symmetrical fixing portions. Each fixing portion includes a curved portion and a straight portion that connect to each other.

[0010] In one embodiment, each fixing groove further includes a positioning portion, which is installed within the fixing groove.

[0014] In one embodiment, each rotating member has a gear section on the other side. [Effects of the Invention]

[0015] As described above, the rotatable sensing module of the embodiment of the present invention can have one or more of the following advantages. (1) In one embodiment of the present invention, a rotatable sensing module includes a rotating seat, an outer housing, a circuit board, a sensor, and two rotating members. The rotating seat includes a first side wall, a second side wall, two connecting parts, and two fixing grooves. The first side wall connects to the second side wall through the two connecting parts described above. A first space is formed between the first side wall and the second side wall. The two fixing grooves described above are provided on the inner surfaces of the first side wall and the second side wall, respectively. The outer housing has two rotating holes, each located on either side of the outer housing. A portion of the outer housing is installed in the first space. The circuit board is installed inside the outer housing. The sensor is electrically connected to the circuit board. The two rotating members described above are each installed in the two rotating holes described above and each rotating member has a clip on one side. The clip of one rotating member is fixed to a fixing groove in the first side wall, and the clip of the other rotating member is fixed to a fixing groove in the second side wall. Each clip includes an arc-shaped portion and a U-shaped portion that connect to each other. Because the rotatable structure described above can realize a rotation function, the sensing range of the rotatable sensing module is adjustable and can therefore meet the needs of different applications. (2) In one embodiment of the present invention, each clip includes an arc-shaped portion and a U-shaped portion that connect to each other, and the clip is shaped like a petal. Due to the structural design of the U-shaped portion of the petal-shaped clip described above, the clip can be easily attached to the corresponding fixing groove. Furthermore, the combination of the arc-shaped portion and the U-shaped portion can effectively prevent relative misalignment between the clip and the rotating seat. Thus, the above-described combination structure of the two clips and the rotating seat can achieve high structural stability and effectively improve the overall structural strength of the rotatable sensing module. (3) In one embodiment of the present invention, each fixing groove further includes a positioning portion, which is installed within the fixing groove. The U-shaped portion of each clip has a slope, which allows the positioning portion to enter the internal space of the corresponding clip through this slope. In this way, the positioning portion can be fitted into the corresponding clip, causing the clip to be fitted more stably into the corresponding fixing groove. This structural design further improves the structural stability of the combination structure of the two clips and the rotating seat described above. Therefore, the overall structural strength of the rotatable sensing module can also be further improved. (4) In one embodiment of the present invention, the outer housing may have two positioning protrusions on each side. Furthermore, each rotating member may have a projection installed on the outer edge of the rotating member. The structural design of the two positioning protrusions described above can limit the range of movement of the projections, thereby limiting the rotation angle of the rotating seat to an ideal range. (5) In one embodiment of the present invention, the rotatable structure of the rotatable sensing module can realize a rotation function, and the sensing range of the rotatable sensing module is adjustable. Therefore, the rotatable sensing module can be applied to various smart systems, such as smart home systems, smart parking systems, and smart factories. Thus, the application of the rotatable sensing module can be broadened and adapted to future development trends. (6) In one embodiment of the present invention, the rotatable structure of the rotatable sensing module can more effectively realize the sensing function and detect moving objects, enabling various smart lighting devices to more effectively provide lighting functions. Therefore, the rotatable sensing module can meet the needs of different applications and has greater flexibility in use. [Brief explanation of the drawing]

[0020] Refer to Figures 1, 2, and 3. Figure 1 is an exploded view of a rotatable sensing module according to a first embodiment of the present invention. Figure 2 is a combined view of the rotatable sensing module according to a first embodiment of the present invention. Figure 3 is a perspective view of the outer casing of the rotatable sensing module according to a first embodiment of the present invention. As shown in the figures, the rotatable sensing module 1 includes a swivel seat 11, an outer casing 12, a circuit board 13, a sensor 14, and two rotatable members 15. The figures also show a lamp tube 2 including an end cap 22 and a lamp cover 21. The rotatable sensing module 1 can be mounted on the end cap 22 of the lamp tube 2. A controller 221 can be installed inside the end cap 22, which may be, for example, a microcontroller (MCU), a central processing unit (CPU), an application-specific integrated circuit chip (ASIC), a field-programmable gate array (FPGA), or other similar component. This embodiment is merely illustrative and not limiting, and the rotatable sensing module 1 can be applied to various devices (e.g., doors, windows, fans, air conditioners, various electronic devices, or various electrical devices) and is not limited to a lamp tube 2.

[0021] 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. 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 installed on the inner surfaces of the first side wall 111 and the second side wall 112, respectively. The rotating seat 11 can be manufactured from metal or plastic.

[0022] The outer housing 12 has two rotating holes RH provided on each side of the outer housing 12, and the edge of each rotating hole RH has a plurality of toothed portions TP. A portion of the outer housing 12 is installed in the first space S1. The outer housing 12 may include two half housings 121, and the two half housings 121 can be combined with each other. The outer housing 12 may be made of metal or plastic. Each side of the outer housing 12 may have two positioning protrusions LB.

[0023] The circuit board 13 is installed inside the outer casing 12. One end of the circuit board 13 is connected to the end cover 22 and electrically connected to the controller 221.

[0024] The sensor 14 can be mounted on the other end of the circuit board 13 and is electrically connected to the circuit board 13. The sensor 14 is oriented towards the second space S2. In one embodiment, the sensor 14 can be a microwave sensor, an infrared sensor, or other similar component. When the sensor 14 detects a moving object (person, vehicle, etc.), the sensor 14 generates a sensing signal, and the controller 221 can control the lamp tube 2 to start or change the brightness or color temperature of the lamp tube 2 based on the sensing signal.

[0025] The two rotating members 15 described above are each installed in the two rotating holes RH described above.

[0026] Naturally, this embodiment is for illustrative purposes only and does not limit the scope of the present invention, and equivalent modifications or changes made based on the rotatable sensing module 1 of this embodiment should still be within the scope of protection of the present invention.

[0027] Refer to Figures 4, 5, and 6. Also, refer to Figures 1 to 3 simultaneously. Figure 4 is a front view of the rotating member of a rotatable sensing module according to a first embodiment of the present invention. Figure 5 is a first perspective view of the rotating member of a rotatable sensing module according to a first embodiment of the present invention. Figure 6 is a second perspective view of the rotating member of a rotatable sensing module according to a first embodiment of the present invention. As shown in the figures, each rotating member 15 has a clip 151 on one side and a gear portion 152 on the other side, which can be fitted together with the aforementioned multiple toothed portions TP of the corresponding rotating hole RH. In this way, the rotating member 15 can rotate. Each rotating member 15 further includes a projection 153 installed on the outer edge of the rotating member 15.

[0028] One of the rotating members 15 has a clip 151 fixed to a fixing groove 114 on the first side wall 111. The other rotating member 15 has a clip 151 fixed to a fixing groove 114 on the second side wall 112. In this way, the rotating seat 11 can rotate relative to the outer housing 12, changing the direction and sensing range of the sensor 14.

[0029] Furthermore, as mentioned above, each side of the outer housing 12 can have two positioning protrusions LB. The structural design of the two positioning protrusions LB described above can limit the range of movement of the protrusion 153, thereby limiting the rotation angle of the rotating seat 11 to an ideal range.

[0030] Each clip 151 is hollow and includes interconnected arc-shaped portions 1511 and U-shaped portions 1512, giving the clip 151 a petal shape or a keyhole shape. The arc-shaped portion 1511 may be a convex arc. In another embodiment, the arc-shaped portion 1511 may be a concave arc. The U-shaped portion 1512 may also have a slope SL located at the bottom of the U-shaped portion 1512.

[0031] Naturally, this embodiment is for illustrative purposes only and does not limit the scope of the present invention, and equivalent modifications or changes made based on the rotatable sensing module 1 of this embodiment should still be within the scope of protection of the present invention.

[0032] Figure 7 is an explanatory diagram of the fixing groove of a rotatable sensing module according to the first embodiment of the present invention. Refer to Figures 1 to 6 simultaneously. As shown in the figure, the fixing groove 114 installed on the first side wall 111 includes two symmetrical fixing parts 1141. Each fixing part 1141 includes a curved part BP and a straight part SP that are connected to each other. The fixing groove 114 installed on the second side wall 112 has the same structure. Due to the above structural design, the shape of the fixing part 1141 corresponds to the petal-shaped clip 151.

[0033] Thus, the U-shaped structure of the petal-shaped clip 151 described above allows the clip 151 to be easily attached to the corresponding fixing groove 114. The combination of the arc-shaped portion 1511 and the U-shaped portion 1512 of the clip 151 effectively prevents relative misalignment between the clip 151 and the rotating seat 11.

[0034] As can be seen from the above, the rotatable sensing module 1 of this embodiment has a rotatable structure. Since the above-described rotatable structure can realize a rotation function, the sensing range of the rotatable sensing module 1 is adjustable and can therefore meet the needs of different applications.

[0035] Furthermore, in this embodiment, each clip 151 includes an interconnected arc-shaped portion 1511 and a U-shaped portion 1512, giving the clip 151 a petal shape. Due to the structural design of the U-shaped portion 1512 of the petal-shaped clip 151, the clip 151 can be easily attached to 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 occurrence of relative displacement between the clip 151 and the rotating seat 11. Therefore, the above-described combination structure of the two clips 151 and the rotating seat 11 can achieve high structural stability and effectively improve the overall structural strength of the rotatable sensing module 1.

[0036] Furthermore, in this embodiment, each side of the outer housing 12 may have two positioning protrusions LB. In addition, each rotating member 15 may have a projection 153 installed on its outer edge. The structural design of the two positioning protrusions LB described above can limit the range of movement of the projections 153, thereby limiting the rotation angle of the rotating seat 11 to an ideal range.

[0037] Furthermore, in this embodiment, the rotatable structure of the rotatable sensing module 1 enables rotation, and therefore the sensing range of the rotatable sensing module 1 is adjustable. Thus, the rotatable sensing module 1 can be applied to various smart systems such as smart home systems, smart parking systems, and smart factories. Consequently, the application of the rotatable sensing module can be broadened and adapted to future development trends.

[0038] Naturally, this embodiment is for illustrative purposes only and does not limit the scope of the present invention, and equivalent modifications or changes made based on the rotatable sensing module 1 of this embodiment should still be within the scope of protection of the present invention.

[0039] Figure 8 is an explanatory diagram of the fixing groove of a rotatable sensing module according to a second embodiment of the present invention. See also Figures 1 to 6. As shown in the figure, the fixing groove 114 installed on the first side wall 111 includes two symmetrically positioned fixing parts 1141. Unlike the previously described embodiment, the fixing groove 114 further includes a positioning part 1142, which is installed within the fixing groove 114. The fixing groove 114 installed on the second side wall 112 has the same structure.

[0040] As described above, the U-shaped portion 1512 of each clip 151 has an inclined surface SL, and the positioning portion 1142 can enter the internal space of the corresponding clip 151 through this inclined surface SL. In this way, the positioning portion 1142 can be fitted into the corresponding clip 151, more stably fitting the clip 151 into the corresponding fixing groove 114. This structural design further improves the structural stability of the combined structure of the two clips 151 and the rotating seat 11. Therefore, the overall structural strength of the rotatable sensing module 1 can also be further improved.

[0041] Naturally, this embodiment is for illustrative purposes only and does not limit the scope of the present invention, and equivalent modifications or changes made based on the rotatable sensing module 1 of this embodiment should still be within the scope of protection of the present invention.

[0042] Figure 9 is a first explanatory diagram showing the usage state of a rotatable sensing module according to a 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 arrow A1 in the figure (or in the opposite direction of arrow A1), that is, adjust the sensing range of the rotatable sensing module 1.

[0043] Naturally, this embodiment is for illustrative purposes only and does not limit the scope of the present invention, and equivalent modifications or changes made based on the rotatable sensing module 1 of this embodiment should still be within the scope of protection of the present invention.

[0044] Figure 10 is a second explanatory diagram showing the usage state of a rotatable sensing module according to a third embodiment of the present invention. As shown in the figure, the rotatable sensing module 1 can be installed in a factory lamp tube 2, and the sensing range of each different rotatable sensing module 1 can be appropriately adjusted. In this way, each of these rotatable sensing modules 1 can sense a user UR at a different location and start the lamp tube 2 in a timely manner.

[0045] The rotatable structure of the rotatable sensing module 1 enables rotation, and therefore the sensing range of the rotatable sensing module 1 is adjustable. Thus, the rotatable sensing module 1 can be applied to various smart systems, such as smart home systems, smart parking systems, and smart factories. Therefore, the applications of the rotatable sensing module 1 can be broadened and adapted to future development trends.

[0046] Naturally, this embodiment is for illustrative purposes only and does not limit the scope of the present invention, and equivalent modifications or changes made based on the rotatable sensing module 1 of this embodiment should still be within the scope of protection of the present invention.

[0047] In summary, according to an embodiment of the present invention, the rotatable sensing module 1 includes a rotating seat 11, an outer housing 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 described above. A first space S1 is formed between the first side wall 111 and the second side wall 112. The two fixing grooves 114 described above are provided on the inner surfaces of the first side wall 111 and the second side wall 112, respectively. The outer housing 12 has two rotating holes RH, each installed on both sides of the outer housing 12. Part of the outer housing 12 is installed in the first space S1. The circuit board 13 is installed inside the outer housing 12. The sensor 14 is electrically connected to the circuit board 13. The two rotating members 15 described above are each installed in the two rotating holes RH described above, and each rotating member 15 has a clip 151 on one side. The clip 151 of one rotating member 15 is fixed to the fixing groove 114 of the first side wall 111, and the clip 151 of the other rotating member 15 is fixed to the fixing groove 114 of the second side wall 112. Each clip 151 includes an arc-shaped portion 1511 and a U-shaped portion 1512 that are connected to each other. Because the above-described rotatable structure can realize a rotation function, the sensing range of the rotatable sensing module 1 is adjustable and can meet the needs of different applications.

[0048] According to embodiments of the present invention, each clip 151 includes an arc-shaped portion 1511 and a U-shaped portion 1512 that are connected to each other, giving the clip 151 a petal shape. Due to the structural design of the U-shaped portion of the petal-shaped clip 151 described above, the clip 151 can be easily installed in the corresponding fixing groove 114. Furthermore, the combination of the arc-shaped portion 1511 and the U-shaped portion 1512 can effectively prevent relative misalignment between the clip 151 and the rotating seat 11. Therefore, the above-described combination structure of the two clips 151 and the rotating seat 11 can achieve high structural stability and effectively improve the overall structural strength of the rotatable sensing module 1.

[0049] Furthermore, according to an embodiment of the present invention, each fixing groove 114 further includes a positioning portion 1142, which is installed within the fixing groove 114. The U-shaped portion 1512 of each clip 151 has an inclined surface SL, which allows the positioning portion 1142 to enter the internal space of the corresponding clip 151 through this inclined surface SL. In this way, the positioning portion 1142 can be fitted into the corresponding clip 151, allowing the clip 151 to be fitted more stably into the corresponding fixing groove 114. This structural design further improves the structural stability of the combination structure of the two clips 151 and the rotating seat 11 described above. Therefore, the overall structural strength of the rotatable sensing module 1 can also be further improved.

[0050] Furthermore, according to embodiments of the present invention, each side of the outer housing 12 may have two positioning protrusions LB. In addition, each rotating member 15 may further have a projection 153 installed on the outer edge of the rotating member 15. The structural design of the two positioning protrusions LB described above can limit the range of movement of the projection 153, thereby limiting the rotation angle of the rotating seat 11 to an ideal range.

[0051] Furthermore, according to embodiments of the present invention, the rotatable structure of the rotatable sensing module 1 enables rotation, and therefore the sensing range of the rotatable sensing module 1 is adjustable. Thus, the rotatable sensing module 1 can be applied to various smart systems, such as smart home systems, smart parking systems, and smart factories. Consequently, the applications of the rotatable sensing module 1 can be broadened and adapted to future development trends.

[0052] Furthermore, according to embodiments of the present invention, the rotatable structure of the rotatable sensing module 1 can more effectively realize the sensing function and detect moving objects, enabling various smart lighting devices to provide lighting functions more effectively. Therefore, the rotatable sensing module 1 can meet the needs of different applications and has greater flexibility in use.
