[0010] In one embodiment, the first included angle and the second included angle are greater than 90° and less than 180°.

[0011] In one embodiment, the first fixed arm, the second fixed arm, the first locking arm and the second locking arm have an L-shaped cross section.

[0012] In one embodiment, the first fixed arm has a first extension portion and a first fixed portion. The first extension portion is connected to the fixed surface and the first fixed portion is connected to the first extension portion. The second fixed arm has a second extension portion and a second fixed portion.

The first fixing part has a positioning groove corresponding to the positioning protrusion.

[0015] In one embodiment, the cover plate is placed over the sensor mounting area and covers the sensor mounting area. Effect of the Invention

[0016] Based on the above, a sensor with a self-aligning fixing structure according to an embodiment of the present invention has one or more of the following advantages. (1) According to one embodiment of the present invention, a sensor includes a mounting cover, a sensor housing, and a sensor module. The mounting cover has a fixing surface. The fixing surface is located on one side of the mounting cover and has a first fixing arm and a second fixing arm, and the first fixing arm is not parallel to the second fixing arm. The sensor housing has a locking surface and a sensor mounting area respectively installed on both sides of the sensor housing. The locking surface has a first locking arm and a second locking arm. The first locking arm is not parallel to the second locking arm, and the first locking arm and the second locking arm correspond to the first locking arm and the second locking arm respectively. The sensor module is installed in the sensor mounting area. The first locking arm and the second locking arm are mutually engaged with the first locking arm and the second locking arm respectively, so that the mounting cover and the sensor housing are fixed to each other. Therefore, the structural design of the fixing surface of the mounting cover and the locking surface of the sensor housing can form a self-aligning fixing structure, so that the user can quickly and conveniently install the sensor. Therefore, the sensor is more convenient to use and can meet the needs of the user. (2) In one embodiment of the present invention, the fixing surface of the mounting cover of the sensor has a first fixing arm. The first fixing arm has a first extending portion and a first fixing portion, and the first fixing portion has a positioning groove. The locking surface of the sensor housing of the sensor has a first support portion. The first support portion has a positioning hole and a positioning post. The positioning post is installed in the positioning hole and has a positioning protrusion corresponding to the positioning groove. Through the above-mentioned automatic auxiliary positioning structure, the mounting cover and the sensor housing can be fixed to each other and have a certain structural strength, and improve the overall structural stability of the sensor. (3) In one embodiment of the present invention, the positioning pillar of the above-mentioned automatic auxiliary positioning structure is located in the positioning hole of the first support part. Therefore, when the first fixing arm and the second fixing arm are not engaged with the first locking arm and the second locking arm, the positioning pillar is deformed, causing the user's hand holding the sensor housing to feel a certain resistance. When the first fixing arm and the second fixing arm are engaged with the first locking arm and the second locking arm, and the positioning protrusion of the positioning pillar is fitted into the positioning groove of the first fixing part, the user can clearly feel the disappearance of the resistance. Therefore, the user can clearly feel the completion of the installation. Therefore, the above-mentioned automatic auxiliary positioning structure can also provide a foolproof function, so that the user can quickly and conveniently install the sensor without the assistance of a technician, and the sensor can better meet the requirements of actual applications. (4) In one embodiment of the present invention, the sensor has an automatic alignment and fixing structure, and the sensor housing is detachable from the mounting cover. In this way, users can choose the sensor housing of the sensor module with different sensor functions according to the needs of actual applications, allowing the sensor to provide different sensor functions. Therefore, the application of the sensor can be made more extensive and can meet the requirements of different applications. (5) In one embodiment of the present invention, the sensor design is simple, so that the manufacturing cost can be reduced while achieving the desired effect, thus effectively improving the practicality of the sensor, effectively improving the shortcomings of the prior art, and adapting to the future development trend.

[0020] Please refer to Figures 1 and 2. Figure 1 is an exploded view of a sensor with a self-aligning and fixing structure of an embodiment of the present invention. Figure 2 is an assembled view of a sensor with a self-aligning and fixing structure of an embodiment of the present invention. As shown in the figure, the sensor 1 includes a mounting cover 11, a sensor housing 12, a sensor module 13 and a cover plate 14. In this embodiment, the sensor 1 may be an AC sensor. In another embodiment, the sensor 1 may be a DC sensor.

[0021] The mounting cover 11 has a mounting surface IS and a fixing surface FS. The mounting surface IS and the fixing surface FS are located on both sides of the mounting cover 11, respectively. The mounting surface IS can be fixed to a ceiling, a wall, or other suitable position of a building. The fixing surface FS has a first fixing arm 111 and a second fixing arm 112, and the first fixing arm 111 is not parallel to the second fixing arm 112. A first reference line R1 passing through a central axis of a connecting surface between the first fixing arm 111 and the fixing surface FS and a second reference line R2 passing through a central axis of a connecting surface between the second fixing arm 112 and the fixing surface FS have a first included angle θ1. In this embodiment, the first included angle θ1 may be an acute angle. That is, the first included angle may be less than 90°. In another embodiment, the first included angle θ1 may be an obtuse angle. That is, the first included angle may be greater than 90° and less than 180°.

[0022] The sensor housing 12 has a lock surface LS and a sensor mounting area DS that are installed on both sides of the sensor housing 12. The lock surface LS has a first lock arm 121 and a second lock arm 122. The first lock arm 121 is not parallel to the second lock arm 122, and the first lock arm 121 and the second lock arm 122 correspond to the first fixed arm 111 and the second fixed arm 112. A third reference line R3 passing through the center axis of the joint surface between the first lock arm 121 and the lock surface LS and a fourth reference line R4 passing through the center axis of the joint surface between the second lock arm 121 and the lock surface LS have a second included angle θ2. The first included angle θ1 is substantially the same as the second included angle θ2. In this embodiment, the second included angle θ2 may be an acute angle. That is, the second included angle θ2 may be less than 90°. In another embodiment, the second included angle θ2 may be an obtuse angle. That is, the second included angle 2 may be greater than 90° and less than 180°.

[0023] The sensor module 13 is installed in a sensor mounting area DS of the sensor housing 12. The sensor mounting area DS has an accommodation space AS, and the sensor housing 12 is installed in the accommodation space AS. The cover plate 14 is installed on the sensor mounting area DS to cover the sensor mounting area DS. In one embodiment, the sensor module 12 may be a microwave sensor. In one embodiment, the sensor module 13 may include an infrared sensor, an optical sensor, a smoke sensor, or other similar components.

[0024] The first fixed arm 111 and the second fixed arm 112 on the fixing surface FS of the mounting cover 11 fit with the first lock arm 121 and the second lock arm 122 on the lock surface LS of the sensor housing 12, allowing the mounting cover 11 and the sensor housing 12 to be fixed to each other.

[0025] The fixing surface FS of the mounting cover 11 has a first fixing arm 111 and a second fixing arm 112, and has a first included angle θ1 between the first fixing arm 111 and the second fixing arm 112, and the locking surface LS of the sensor housing 12 has a first locking arm 121 and a second locking arm 122, and has a second included angle θ2 between the first locking arm 121 and the second locking arm 122. Therefore, the structural design of the fixing surface FS of the mounting cover 11 and the locking surface LS of the sensor housing 12 can form an automatic alignment structure, so that the user can intuitively align the front end of the first locking arm 121 and the front end of the second locking arm 122 (the distance between both ends is short) with the rear end of the first fixing arm 111 and the rear end of the second fixing arm 112 (the distance between both ends is long), and can move the sensor housing 12 toward the mounting cover 11 and fix the sensor housing 12 to the mounting cover 11. In this way, the user can quickly and easily install the sensor 1. Therefore, the sensor 1 is more convenient to use and can meet the requirements of users.

[0026] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or alterations made based on the sensor with the automatic alignment fixing structure of this embodiment should still fall within the protection scope of the present invention.

[0027] FIG. 3 is an explanatory diagram of the structure of a sensor equipped with an automatic alignment fixing structure according to an embodiment of the present invention. As shown in the figure, the first fixed arm 111 has a first extension 1111 and a first fixed part 1112. The first extension 1111 is connected to the fixed surface FS, the first fixed part 1112 is connected to the first extension 1111, and the cross section of the first fixed arm 111 is L-shaped. Similarly, the second fixed arm 112 has a second extension 1121 and a second fixed part 1122. The second extension 1121 is connected to the fixed surface FS, the second fixed part 1122 is connected to the second extension 1121, and the cross section of the second fixed arm 112 is L-shaped. The first fixed part 1112 extends in the direction of the central axis Mx1 of the fixed surface FS. The second fixed part 1122 also extends in a direction approaching the central axis Mx1 of the fixed surface FS. Therefore, the extension direction of the first fixing portion 1112 is opposite to the extension direction of the second fixing portion 1122 .

[0028] The first lock arm 121 has a first support portion 1211 and a first lock portion 1212. The first support portion 1211 is connected to the lock surface LS, the first lock portion 1212 is connected to the first support portion 1211, and the cross section of the first lock arm 121 is L-shaped. Similarly, the second lock arm 122 has a second support portion 1221 and a second lock portion 1222. The second support portion 1221 is connected to the lock surface LS, the second lock portion 1222 is connected to the second support portion 1221, and the cross section of the second lock arm 122 is L-shaped. The first lock portion 1212 extends in a direction away from the central axis Mx2 of the lock surface LS. The second lock portion 1222 also extends in a direction away from the central axis Mx2 of the lock surface LS. Therefore, the extension direction of the first lock portion 1212 is opposite to the extension direction of the second lock portion 1222.

[0029] With the above structural design, the first fixed arm 111 and the second fixed arm 112 are fitted with the first locking arm 121 and the second locking arm 122, respectively, to fix the mounting cover 11 and the sensor housing 12 to each other. Therefore, the structural design of the fixing surface FS of the mounting cover 11 and the locking surface LS of the sensor housing 12 can form an automatic alignment structure, so that the user can quickly and conveniently install the sensor 1. Therefore, the sensor 1 is more convenient to use and can meet the requirements of the user.

[0030] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or alterations made based on the sensor with the automatic alignment fixing structure of this embodiment should still fall within the protection scope of the present invention.

[0031] 4, 5 and 6 are first, second and third partial enlarged views of a sensor equipped with an automatic alignment and fixing structure according to an embodiment of the present invention. As shown in FIG. 4, the first support part 1211 of the first lock arm 121 has a positioning hole PH and a positioning post PS. The positioning post PS is installed in the positioning hole PH. The positioning post PS has a positioning protrusion PN. The extension direction of the positioning protrusion PN is the same as the extension direction of the first lock part 1212.

[0032] As shown in FIG. 5, the first fixed portion 1112 of the first fixed arm 111 has a positioning groove PR corresponding to the positioning protrusion PN.

[0033] 6, when a user grasps the sensor housing 12 and moves the sensor housing 12 toward the mounting cover 11, the first fixed arm 111 and the second fixed arm 112 have not yet engaged with the first lock arm 121 and the second solid arm 122. At this time, the positioning post PS is deformed, causing a certain resistance to the user's hand grasping the sensor housing 12.

[0034] The first fixed arm 111 and the second fixed arm 112 are fitted with the first locking arm 121 and the second locking arm 122, and when the positioning protrusion PN of the positioning post PS is fitted into the positioning groove PR of the first fixed part 1112, the user can clearly feel the disappearance of the above-mentioned resistance force. Therefore, the user can clearly feel the completion of installation. With the above-mentioned automatic auxiliary positioning structure, the mounting cover 11 and the sensor housing 12 can be fixed to each other and have a certain structural strength, improving the overall structural stability of the sensor 1.

[0035] In addition, the positioning post PS of the above-mentioned automatic auxiliary positioning structure is located in the positioning hole PH of the first support part 1211. Therefore, when the first fixed arm 111 and the second fixed arm 112 are not engaged with the first locking arm 121 and the second locking arm 122, the positioning post PS is deformed, causing the user's hand holding the sensor housing 12 to feel a certain resistance. When the first fixed arm 111 and the second fixed arm 112 are engaged with the first locking arm 121 and the second locking arm 122 and the positioning protrusion PN of the positioning post PS is fitted into the positioning groove PR of the first fixed part 1112, the user can clearly feel the disappearance of the resistance. Therefore, the user can clearly feel the completion of the installation. Therefore, the above-mentioned automatic auxiliary positioning structure can provide a fool-proof function, so that the user can quickly and conveniently install the sensor 1 without the assistance of a technician, and the sensor 1 can be adapted to the needs of the actual application.

[0036] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or alterations made based on the sensor with the automatic alignment fixing structure of this embodiment should still fall within the protection scope of the present invention.

[0037] In addition, the mounting structure of the conventional sensor is relatively complicated in design, so that the overall cost of these sensors is greatly increased and their application is greatly limited. In addition, the mounting structure design of the conventional sensor is relatively complicated, so that users cannot quickly and conveniently install these sensors, or need the assistance of a technician. Therefore, the conventional sensor is very inconvenient to use and cannot meet the requirements of users. In addition, due to the structural limitations of the conventional sensor, these sensors can usually only provide one sensing function. Therefore, when a user needs another sensing application, the user can only remove the current sensor and install a sensor with another sensing function. In contrast, according to an embodiment of the present invention, the sensor includes a mounting cover, a sensor housing, and a sensor module. The mounting cover has a fixing surface. The fixing surface is located on one side of the mounting cover and has a first fixing arm and a second fixing arm, and the first fixing arm is not parallel to the second fixing arm. The sensor housing has a locking surface and a sensor mounting area respectively installed on both sides of the sensor housing. The locking surface has a first locking arm and a second locking arm. The first locking arm is not parallel to the second locking arm, and the first locking arm and the second locking arm correspond to the first fixed arm and the second fixed arm, respectively. The sensor module is installed in the sensor mounting area. The first fixed arm and the second fixed arm are fitted with the first locking arm and the second locking arm, respectively, to fix the mounting cover and the sensor housing to each other. Therefore, the structural design of the fixing surface of the mounting cover and the locking surface of the sensor housing can form a self-aligning fixing structure, so that the user can quickly and conveniently install the sensor. Therefore, the sensor is more convenient to use and can meet the needs of the user.

[0038] Also, according to an embodiment of the present invention, the fixing surface of the mounting cover of the sensor has a first fixing arm. The first fixing arm has a first extending portion and a first fixing portion, and the first fixing portion has a positioning groove. The locking surface of the sensor housing of the sensor has a first support portion. The first support portion has a positioning hole and a positioning post. The positioning post is installed in the positioning hole and has a positioning protrusion corresponding to the positioning groove. Through the above-mentioned automatic auxiliary positioning structure, the mounting cover and the sensor housing can be fixed to each other and have a certain structural strength, and improve the overall structural stability of the sensor.

[0039] Also, according to the embodiment of the present invention, the positioning pillar of the above-mentioned automatic auxiliary positioning structure is located in the positioning hole of the first support part. Therefore, when the first fixing arm and the second fixing arm are not engaged with the first locking arm and the second locking arm, the positioning pillar will be deformed, causing the user's hand holding the sensor housing to feel a certain resistance. When the first fixing arm and the second fixing arm are engaged with the first locking arm and the second locking arm, and the positioning protrusion of the positioning pillar is fitted into the positioning groove of the first fixing part, the user can clearly feel the disappearance of the resistance. Therefore, the user can clearly feel the completion of the installation. Therefore, the above-mentioned automatic auxiliary positioning structure can also provide a foolproof function, so that the user can quickly and conveniently install the sensor without the assistance of a technician, and the sensor can better meet the requirements of actual application.

[0040] In addition, according to the embodiment of the present invention, the sensor has an automatic alignment and fixing structure, and the sensor housing is detachable from the mounting cover. In this way, users can choose the sensor housing of the sensor module with different sensor functions according to the needs of actual applications, and the sensor can provide different sensor functions. Therefore, the application of the sensor can be more extensive and can meet the requirements of different applications.

[0041] In addition, according to the embodiment of the present invention, the sensor is designed simply, so that the manufacturing cost can be reduced while achieving the desired effect. Therefore, the practicality of the sensor can be effectively improved, the shortcomings of the prior art can be effectively improved, and the sensor can be adapted to the future development trend. From the above, it can be seen that the sensor with the automatic alignment and fixing structure according to the embodiment of the present invention can indeed achieve excellent technical effects.

[0042] 7 is an explanatory diagram of a state in which a sensor having an automatic alignment and fixing structure according to an embodiment of the present invention is used. As shown in the figure, the sensor 1 in this embodiment is an infrared sensor and can be fixed to a ceiling CL of a building (the sensor 1 can also be fixed to a wall of a building or other suitable position). When the sensor 1 detects a user UR, the sensor 1 can transmit a detection signal to multiple lighting devices LD to turn on these lighting devices LD.

[0043] A user can replace the sensor housing 12 with a sensor module 13 having different sensor functions according to the needs of actual applications, so that the sensor 1 can provide different sensor functions. Therefore, the application of the sensor 1 can be made more extensive and can be adapted to the requirements of different applications.

[0044] The design of the sensor 1 is simple, so that the desired effect can be achieved while reducing the cost. In this way, the practicality of the sensor 1 can be effectively improved. Therefore, the sensor 1 can not only effectively improve the shortcomings of the prior art, but also adapt to the future development trend.

[0045] Of course, this embodiment is only used for illustrative purposes and does not limit the scope of the present invention, and any equivalent modifications or alterations made based on the sensor with the automatic alignment fixing structure of this embodiment should still fall within the protection scope of the present invention.

The sensor module is installed in the sensor mounting area. The first locking arm and the second locking arm are mutually engaged with the first locking arm and the second locking arm respectively, making the mounting cover and the sensor housing fixed to each other. Therefore, the structural design of the fixing surface of the mounting cover and the locking surface of the sensor housing can form one self-aligning fixing structure, so that the user can quickly and conveniently install the sensor. Therefore, the sensor is more convenient to use and can meet the needs of the user.

[0048] Also, according to the embodiment of the present invention, the positioning pillar of the above-mentioned automatic auxiliary positioning structure is located in the positioning hole of the first support part. Therefore, when the first fixing arm and the second fixing arm are not engaged with the first locking arm and the second locking arm, the positioning pillar will be deformed, causing the user's hand holding the sensor housing to feel a certain resistance.
