Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0035] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0039] See Figure 1 , Figure 2 , Figure 3 and Figure 4 One embodiment of this application provides a detection device 10 including a sensor 101 and a mounting base 102, wherein the sensor 101 is disposed on the mounting base 102.

[0040] See Figure 5 , Figure 6 and Figure 7 In some embodiments, the sensor 101 includes a housing assembly 100 and a detection assembly 200. The housing assembly 100 includes a housing 110 and a light-transmitting element 120. The housing 110 may be generally cylindrical and may form a generally cylindrical inner cavity 111. A portion of the mounting base 102 can be inserted into the inner cavity 111, thus connecting the mounting base 102 to the sensor 101. The light-transmitting element 120 has semi-transparent properties and is used to transmit infrared light. The light-transmitting element 120 is disposed at one end of the housing 110. The housing assembly 100 may also include a button 140 disposed on the housing 110, which allows an operator to control the activation of the sensor 101.

[0041] See Figure 7 and Figure 8In some embodiments, the detection component 200 is disposed within the housing 110, i.e., the detection component 200 is located within the inner cavity 111 of the housing 110. The detection component 200 includes a support member 230, a first detection unit 210, and a second detection unit 220. The first detection unit 210 includes a first circuit board 211 and a radar sensor 212. The first circuit board 211 is disposed on the support member 230, and the radar sensor 212 is disposed on the first circuit board 211. The radar sensor 212 can detect using millimeter-wave radar, but can also use ultrasound or laser for sensing. The radar sensor 212 can detect the presence of a human body and its movement. The second detection unit 220 includes a second circuit board 221 and an infrared sensor 222. The second circuit board 221 is disposed on the support member 230, and the infrared sensor 222 is disposed on the second circuit board 221. The second circuit board 221 and the first circuit board 211 are electrically connected to each other. The infrared sensor 222 can also detect the presence of a human body and its movement.

[0042] See Figure 5 , Figure 7 and Figure 8 When sensor 101 only has radar sensor 212 or infrared sensor 222, meaning sensor 101 can only perform single-level detection, it cannot accurately detect subtle movements such as human breathing, thus affecting the detection accuracy and sensitivity of sensor 101. However, in the sensor 101 of the above embodiment, since radar sensor 212 and infrared sensor 222 detect simultaneously, ensuring dual detection, sensor 101 can accurately detect subtle movements such as human breathing, ultimately improving the detection accuracy and sensitivity of sensor 101.

[0043] See Figure 5 , Figure 7 and Figure 8 In some embodiments, the first circuit board 211 and the second circuit board 221 are arranged along the axial direction of the housing 110, such that the first circuit board 211 and the second circuit board 221 are spaced a certain distance apart along the axial direction of the housing 110. One of the first circuit board 211 and the second circuit board 221 is provided with a plug and the other with a socket, which are located in the gap between the first circuit board 211 and the second circuit board 221. Through the mutual cooperation of the plug and the socket, the first circuit board 211 and the second circuit board 221 can be electrically connected. The first circuit board 211 can be closer to the light-transmitting element 120 than the second circuit board 221, which can improve the detection accuracy of the radar sensor 212 to a certain extent.

[0044] See Figure 5 , Figure 7 and Figure 8In some embodiments, a through hole 2111 is provided on the first circuit board 211, extending through the entire first circuit board 211 along its thickness direction. An infrared sensor 222 protrudes from the second circuit board 221. A portion of the infrared sensor 222 is located in the gap between the first and second circuit boards 211, while the other portion is inserted into the through hole 2111. Therefore, infrared light transmitted from the outside through the light-transmitting element 120 into the housing 110 can be received by the infrared sensor 222, ensuring effective detection of infrared light. The cooperation between the infrared sensor 222 and the through hole 2111 allows for precise positioning of the second detection unit 220, thereby improving the installation efficiency and accuracy of the second detection unit 220. It also allows the infrared sensor 222 to fully utilize the existing space of the through hole 2111, thus achieving a compact structure for the sensor 101.

[0045] See Figure 5 , Figure 7 and Figure 8 In some embodiments, the first detection unit 210 further includes a temperature and humidity sensor 214, which is disposed on the first circuit board 211. The temperature and humidity sensor 214 can detect the temperature and humidity of the external environment, thereby improving the diversity of the detection functions of the sensor 101. The first detection unit 210 may also include a light sensor 213, which is disposed on the first circuit board 211. The light sensor 213 can detect the light intensity in the external environment, for example, whether it is day or night, thus also improving the diversity of the detection functions of the sensor 101. In the presence of the light sensor 213, the housing assembly 100 further includes a light guide 130, which is disposed on the housing 110 and is curved, and is positioned close to the light sensor 213 so that the light guide 130 can guide the light from the external environment to the light sensor 213. Since the light guide 130 is curved, its area can be reasonably increased within a limited three-dimensional space, thereby increasing the light transmission angle and thus increasing the amount of light transmitted by the light guide 130, ultimately improving the detection accuracy of the photosensitive element 213.

[0046] In some embodiments, radar sensor 212 protrudes from the surface of the first circuit board 211 facing away from the second circuit board 221, photosensor 213 also protrudes from the surface of the first circuit board 211 facing away from the second circuit board 221, and temperature and humidity sensor 214 protrudes from the surface of the first circuit board 211 facing the second circuit board 221. Infrared sensor 222 protrudes from the surface of the second circuit board 221 facing the first circuit board. This allows the radar sensor 212, photosensor 213, temperature and humidity sensor 214, and infrared sensor 222 to fully utilize the gap between the first circuit board 211 and the second circuit board 221, as well as the space of the inner cavity 111, thereby achieving a reasonable layout.

[0047] See Figure 5 , Figure 7 and Figure 8 In some embodiments, the support member 230 is detachably connected to the housing 110, for example, the support member 230 and the housing 110 can be connected by a snap-fit ​​connection. The support member 230 includes a support body 231 and support columns 232. The support body 231 has a support surface 231a, and the support columns 232 protrude from the support surface 231a. There are multiple support columns 232, which are spaced apart circumferentially along the support body 231, that is, two adjacent support columns 232 are spaced apart at a certain angle circumferentially along the support body 231. For example, there can be three support columns 232. A second circuit board 221 is supported on the support surface 231a, and a first circuit board 211 is supported on the end of the support column 232 away from the support surface 231a. The first circuit board 211 can be bolted to the end of the support column 232. Meanwhile, the second circuit board 221 has multiple clearance holes 221a, the number of which is equal to the number of support pillars 232 and they correspond one-to-one. The clearance holes 221a penetrate the second circuit board 221 along its thickness direction, and the support pillars 232 pass through the clearance holes 221a, thus enabling the second circuit board 221 to be supported on the support surface 231a. By setting the support pillars 232 and clearance holes 221a, a certain distance can be maintained between the first circuit board 211 and the second circuit board 221 along the axial direction of the support member 230.

[0048] See Figure 5 and Figure 9In some embodiments, the sensor 101 further includes a power supply assembly 300, which includes a bracket 310 and multiple batteries 320, such as two batteries 320. The multiple batteries 320 are connected in parallel within the bracket 310 and electrically connected to the second circuit board 221. Given that there are multiple batteries 320, the frequency of battery replacement can be reduced, reasonably extending the usage time of the power supply assembly 300 and the working time of the sensor 101, ultimately improving the ease of use of the sensor 101. The bracket 310 and the support member 230 are detachably connected, for example, by bolts. The bracket 310 includes two support plates 311 and multiple side plates 312. The number of support plates 311 is two, and the number of side plates 312 can be multiple, such as two, three, or four. The two support plates 311 are spaced apart along the axial direction of the housing 110, and the multiple side plates 312 extend along the axial direction of the housing 110, connecting the edges of the two support plates 311. The multiple side plates 312 are spaced apart circumferentially along the housing 110. The support plates 311 and side plates 312 form a limiting cavity 313. Multiple batteries 320 are stacked and disposed within the limiting cavity 313. The limiting cavity 313 effectively limits the positioning of the batteries 320, thereby improving the installation efficiency and accuracy of the batteries 320. By setting the limiting cavity 313, the battery 320 can be installed into the limiting cavity 313 in a direction perpendicular to the axial direction of the outer shell 110. In simple terms, it can be understood as being installed into the limiting cavity 313 from the side of the bracket 310, thereby improving the ease of assembly of the power supply component 300.

[0049] See Figure 5 and Figure 9 In some embodiments, the power supply assembly 300 further includes a negative electrode spring 330 and a positive electrode spring 340. The negative electrode spring 330 is electrically connected to the battery 320 and the second circuit board 221, and the positive electrode spring 340 is also electrically connected to the battery 320 and the second circuit board 221. The positive electrode spring 340 is attached to the side plate 312, and the negative electrode spring 330 includes an abutment portion 331. The two ends of the abutment portion 331 can be respectively inserted into the two side plates 312. The abutment portion 331 and the two support plates 311 are spaced apart along the axial direction of the housing 110, which can be understood as the abutment portion 331 being suspended in the limiting cavity 313. When there are two batteries 320, the two batteries 320 are respectively located on opposite sides of the abutment portion 331 along the axial direction of the housing 110, so that the abutment portion 331 is sandwiched between the two batteries 320, which facilitates the simultaneous electrical connection of the abutment portion 331 with the two batteries 320.

[0050] See Figure 5 and Figure 9In some embodiments, the bracket 310 further includes a lug 314, a retaining ring 315, and a fastener 316. The lug 314 protrudes from one of the side plates 312, such that the lug 314 is located outside the limiting cavity 313. The fastener 316 can be a bolt, which passes through the lug 314 and is threadedly connected to the support body 231 of the support member 230. Therefore, the bolted connection between the bracket 310 and the support member 230 ensures that the negative electrode spring 330 and the positive electrode spring 340 are in close contact with the springs on the second circuit board 221 to prevent loosening, thereby improving the stability and reliability of the electrical connection between the battery 320 and the second circuit board 221. The retaining ring 315 is engaged outside the fastener 316 and abuts against the lug 314. By providing a retaining ring 315, when the fastener 316 is released from the support member 230 and the bracket 310 is unloaded from the support body 231, the retaining ring 315 effectively prevents the fastener 316 from falling off the lug 314, thus improving the ease of assembly of the power supply assembly 300. A receiving cavity 2311 can be provided within the support body 231 of the support member 230, and the bracket 310 is at least partially housed within the receiving cavity 2311. Therefore, the bracket 310 can fully utilize the existing space of the receiving cavity 2311, thereby improving the structural compactness of the sensor 101.

[0051] See Figure 5 , Figure 10 and Figure 11 In some embodiments, the mounting base 102 includes a base body 400, which includes a first mounting unit 410, a second mounting unit 420, and a connector 430. The first mounting unit 410 is fixedly connected to the housing 110 of the sensor 101. Along the thickness direction of the first mounting unit 410, the second mounting unit 420 is spaced apart from the first mounting unit 410 and fixed to a support, thus achieving a fixed connection between the entire detection device 10 and the support. The support can be a desktop, wall, building, or street lamp pole, etc. The connector 430 connects the first mounting unit 410 and the second mounting unit 420, allowing the first mounting unit 410 to rotate relative to the second mounting unit 420 around a rotating axis extending in multiple directions. This allows for various adjustments to the position of the sensor 101, ensuring the sensor 101 is accurately positioned at a specified location, thereby improving the applicability of the sensor 101 to various application scenarios.

[0052] In some embodiments, the connector 430 includes a connecting portion 431 and a ball head 432, which are interconnected. One of the first mounting unit 410 and the second mounting unit 420 is fixedly connected to the connecting portion 431, while the other has a ball hole 413 that rotatably engages with the ball head 432. Therefore, through the engagement of the ball head 432 and the ball hole 413, the ball head 432 can rotate relative to the ball hole 413 in three-dimensional space around an axis extending in any direction. This causes the first mounting unit 410 to rotate relative to the second mounting unit 420 in three-dimensional space around an axis extending in any direction, ultimately causing the sensor 101 to rotate relative to the support in three-dimensional space around an axis extending in any direction. In other embodiments, the connector 430 can be other cams, gears, or linkage mechanisms, as long as it enables the first mounting unit 410 to rotate relative to the second mounting unit 420 around axes extending in multiple directions via the connector 430.

[0053] If sensor 101 cannot rotate relative to the load, or if sensor 101 can only rotate relative to the load around a limited number of axes, then sensor 101 can only detect within a limited detection range. This can be understood as the detection position of sensor 101 being stepped adjustable, thus affecting the detection range of sensor 101. However, for the sensor 101 in the above embodiment, given that the ball head 432 and the ball hole 413 cooperate to allow sensor 101 to rotate relative to the load around axes extending in any direction in three-dimensional space, the detection position of sensor 101 can be understood as steplessly adjustable. This allows the sensor 101 to automatically adjust its monitoring direction and angle, thereby increasing its detection range and applicability to various detection conditions. It also improves the ease of use of sensor 101. It is understood that not only sensor 101 can be connected to mounting base 102, but other moving devices such as cameras can also be connected to mounting base 102. When other moving devices such as cameras are connected to the mounting base 102, the position of the moving device can be steplessly adjusted through the cooperation of the ball head 432 and the ball hole 413, thereby improving the applicability of the moving device to various application scenarios.

[0054] See Figure 11 , Figure 12 and Figure 13In some embodiments, the connecting portion 431 is detachably connected to the second mounting unit 420, for example, the connecting portion 431 and the second mounting unit 420 can be bolted together; the ball hole 413 is formed on the first mounting unit 410. In other embodiments, the connecting portion 431 can be fixedly connected to the first mounting unit 410, and the ball hole 413 can be formed on the second mounting unit 420. The first mounting unit 410 may include a first main cover 411, a first pressure cover 412, and a flexible element 414. The first main cover 411 and the first pressure cover 412 are detachably connected, for example, by threaded connection. The first main cover 411 and the first pressure cover 412 together form a ball hole 413. The flexible element 414 may be made of silicone material, thus possessing excellent flexibility. The flexible element 414 is housed within the ball hole 413. When the ball head 432 engages with the ball hole 413, the ball head 432 will abut against the flexible element 414, that is, the flexible element 414 is abutted between the ball head 432 and the first mounting unit 410. By providing the flexible element 414, the rotational friction between the ball head 432 and the flexible element 414 can be reasonably adjusted, which can also be understood as the damping force of the ball head 432 during rotation, that is, adjusting the damping force of the sensor 101 relative to the load. Obviously, the greater the compression of the flexible component 414, the greater the friction between the ball head 432 and the flexible component 414.

[0055] See Figure 11 and Figure 14 In some embodiments, the second mounting unit 420 is provided with a socket 4211, which mates with the connecting part 431. The cross-sectional shapes of the socket 4211 and the connecting part 431 are matched and are both non-circular. For example, the outer surface of the connecting part 431 includes an arc surface and a flat surface, and the inner wall surface of the socket 4211 also includes an arc surface and a flat surface. When the socket 4211 mates with the connecting part 431, the arc surfaces of the connecting part 431 and the socket 4211 abut against each other, and the flat surfaces of the connecting part 431 and the socket 4211 abut against each other. This can effectively prevent the connecting part 431 from rotating relative to the second mounting unit 420.

[0056] See Figure 11 , Figure 12 and Figure 13In some embodiments, the second mounting unit 420 includes a second main cover 421, a second pressure cover 422, and a magnetic element 423. The second main cover 421 and the second pressure cover 422 are detachably connected, for example, by means of a snap-fit ​​connection. The magnetic element 423 is located within the space enclosed by the second main cover 421 and the second pressure cover 422, and is fixedly connected to the second pressure cover 422, for example, by adhesive bonding. The aforementioned insertion hole 4211 can be provided on the second main cover 421. When the second pressure cover 422 contacts the carrier, the magnetic element 423 can generate a magnetic attraction force with the carrier, so that the entire mounting base 102 is fixed to the carrier by the magnetic attraction force.

[0057] See Figure 11 , Figure 12 and Figure 13 In some embodiments, the sensor 101 and the mounting base 102 are snap-fitted together, allowing the sensor 101 to be detached from the mounting base 102. Therefore, when the sensor 101 needs to be replaced, it can be directly removed from the mounting base 102, or a new sensor 101 can be installed onto the mounting base 102, thus improving the ease of use of the detection device 10. It is understood that when the sensor 101 is damaged, it can be removed from the mounting base 102 and replaced with a new sensor; the entire detection device 10 cannot be scrapped, thus reducing the maintenance cost of the detection device 10. In other embodiments, the sensor 101 and the mounting base 102 can be threaded together, also allowing the sensor 101 to be detached from the mounting base 102, similarly improving the ease of use of the detection device 10 and reducing its maintenance cost.

[0058] In some embodiments, the mounting base 102 may further include sliding latches 520 and fixed latches 530. A locking hole 112 is recessed on the inner wall surface of the inner cavity 111 of the housing 110. The sum of the number of sliding latches 520 and fixed latches 530 is equal to the number of locking holes 112. This allows the sliding latches 520 and fixed latches 530 to engage with different locking holes 112. For ease of description, refer to [reference needed]. Figure 2Some of the slots 112 are designated as first slots 1121, and the remaining slots 112 are designated as second slots 1122. A sliding buckle 520 engages with the first slots 1121, and a fixing buckle 530 engages with the second slots 1122, thereby establishing a snap-fit ​​connection between the mounting base 102 and the sensor 101. The shapes of the first slots 1121 and the second slots 1122 can be the same or different. The fixing buckle 530 is fixedly connected to the base body 400, and the sliding buckle 520 is slidably connected to the base body 400, allowing the sliding buckle 520 to slide closer to or further away from the first slots 1121. In other embodiments, for example, the sensor 101 includes a sliding buckle 520 and a fixed buckle 530, which can be disposed on the housing 110. The first latching hole 1121 and the second latching hole 1122 can be disposed on the base body 400, which can also realize the latching connection between the sensor 101 and the mounting base 102. For another example, the sensor 101 includes a sliding buckle 520, and the base body 400 has a first latching hole 1121; while the mounting base 102 includes a fixed buckle 530, and the sensor 101 has a second latching hole 1122. Yet another example, the base body 400 includes a sliding buckle 520, and the sensor 101 has a first latching hole 1121; while the sensor 101 includes a fixed buckle 530, and the base body 400 has a second latching hole 1122. In some embodiments, the number of fixed latches 530 may be greater than or equal to the number of sliding latches 520; for example, there may be two fixed latches 530 and one sliding latch 520. Both the fixed latches 530 and the sliding latches 520 may be disposed on the first main body cover 411 of the first mounting unit 410. The fixed latches 530 and the sliding latches 520 are spaced apart circumferentially along the first main body cover 411.

[0059] See Figure 11 , Figure 12 and Figure 13 In some embodiments, the mounting base 102 may further include an elastic element 510, which may be a spring. The sliding buckle 520 is slidably connected to the first mounting unit 410 along an axial direction perpendicular to the connector 430, and the elastic element 510 abuts against the sliding buckle 520 and the first mounting unit 410. For example, the first mounting unit 410 may have a sliding hole 4113, and the elastic element 510 may be received in the sliding hole 4113. The sliding buckle 520 slides and engages with the sliding hole 4113, thus realizing a sliding connection between the sliding buckle 520 and the first mounting unit 410. Of course, the sliding buckle 520 may also be provided with a sliding hole 4113 that slides and engages with the first mounting unit 410.

[0060] See Figure 11 , Figure 12 and Figure 13In some embodiments, the first main body cover 411 of the first mounting unit 410 has a bottom surface 4111 and an outer peripheral surface 4112. The bottom surface 4111 faces the second mounting unit 420 and is disposed away from the sensor 101. The outer peripheral surface 4112 is annular and surrounds the bottom surface 4111. The sliding hole 4113 includes a first sliding section 4113a and a second sliding section 4113b. The first sliding section 4113a and the second sliding section 4113b are interconnected. The first sliding section 4113a is formed by a recess in a portion of the outer peripheral surface 4112, and the second sliding section 4113b is formed by a recess in a portion of the bottom surface 4111. The sliding buckle 520 includes a sliding portion 521 and a force-applying portion 522. The sliding portion 521 is slidably engaged with the first sliding segment 4113a, and the force-applying portion 522 is slidably engaged with the second sliding segment 4113b. The force-applying portion 522 protrudes from the bottom surface 4111, such that one end of the force-applying portion 522 is located outside the second sliding segment 4113b and closer to the second mounting unit 420 relative to the sliding portion 521. The elastic member 510 can abut between the first main body cover 411 and the sliding portion 521.

[0061] The first sliding section 4113a has an opening on its outer peripheral surface 4112. When the elastic member 510 and / or the user apply a force toward the opening to the force-applying part 522, the force-applying part 522 gradually moves closer to the opening in the second sliding section 4113b. The sliding part 521 slides relative to the first sliding section 4113a, so that the length of the sliding part 521 extending out of the opening beyond the first mounting unit 410 increases, that is, the sliding part 521 gradually extends outward, so that the sliding part 521 cooperates with the snap hole 112 to achieve a snap-fit ​​connection with the outer casing 110. When the user applies a force to the force-applying part 522 in the opposite direction to the opening, the force-applying part 522 gradually moves away from the opening in the second sliding section 4113b. The sliding part 521 slides relative to the first sliding section 4113a, so that the length of the sliding part 521 extending from the opening to the first mounting unit 410 is reduced. That is, the sliding part 521 gradually contracts inward, the elastic member 510 is compressed and stores energy, so that the sliding part 521 completely disengages from the locking hole 112, thereby releasing the sliding buckle 520 from the locking hole 112 to release the buckle connection with the outer casing 110.

[0062] During the connection process between the mounting base 102 and the sensor 101, the first mounting unit 410 of the mounting base 102 is first inserted into the inner cavity 111 of the housing 110, and a certain pressure is applied to the mounting base 102. The fixing buckle 530 will engage with the locking hole 112. Under the squeezing action of the housing 110, the sliding buckle 520 gradually contracts inward, and the elastic element 510 is compressed and stores energy, thereby reducing the interference force between the sliding buckle 520 and the housing 110. When the sliding buckle 520 is aligned with the locking hole 112, the sliding buckle 520 will produce a "stepping into space" effect, and the elastic element 510 will release energy and push the sliding buckle 520 to gradually extend outward, so that the sliding buckle 520 engages with the locking hole 112. When the fixing buckle 530 and the sliding buckle 520 engage with different locking holes 112 respectively, the buckle connection between the mounting base 102 and the sensor 101 can be realized. When it is necessary to unload the sensor 101 from the mounting base 102, a force can first be applied to the force application part 522 of the sliding buckle 520 to disengage the sliding buckle 520 from the locking hole 112. Then, a pulling force is applied to the sensor 101 to disengage the fixing buckle 530 from the locking hole 112. This will release the buckling connection between the fixing buckle 530 and the sliding buckle 520 and the housing 110, thereby unloading the sensor 101 from the mounting base 102.

[0063] If the first mounting unit 410 is equipped with all fixing clips 530 and no sliding clips 520, during the assembly of the mounting base 102 and the sensor 101, a large interference resistance will be generated between the fixing clips 530 and the housing 110. Therefore, a large pressure needs to be applied to the mounting base 102 or the sensor 101 to achieve the installation. Similarly, during the disassembly of the mounting base 102 and the sensor 101, a large interference resistance will also be generated between the fixing clips 530 and the housing 110. Therefore, a large pulling force also needs to be applied to the mounting base 102 or the sensor 101 to achieve the disassembly. Therefore, during the assembly and disassembly of the entire detection device 10, the user will need to exert a large amount of force, thereby increasing the difficulty of assembling and disassembling the detection device 10 and ultimately affecting the ease of use of the detection device 10.

[0064] Regarding the detection device 10 in the above embodiments, given the presence of the sliding latch 520, during the assembly process of the detection device 10, the sliding latch 520 will first gradually retract inward, thereby reducing the interference resistance between the sliding latch 520 and the outer shell 110, and also reducing the assembly resistance between the sensor 101 and the mounting base 102. During the disassembly process of the detection device 10, a force can first be applied to the force-applying part 522 of the sliding latch 520, causing the sliding latch 520 to disengage from the latch hole 112, thereby eliminating the interference resistance between the sliding latch 520 and the outer shell 110, and thus reducing the disassembly resistance between the sensor 101 and the mounting base 102. This will reduce the difficulty of assembling and disassembling the detection device 10, ultimately improving the ease of use of the detection device 10.

[0065] See Figure 2 In some embodiments, the outer casing 110 includes a rib 113, which protrudes from the inner wall of the inner cavity 111 and extends axially along the sensor 101. There can be one or more ribs 113. A guide groove 4114 can be provided on the first main body cover 411 of the base body 400. During the insertion of the first main body cover 411 into the inner cavity 111, the rib 113 slides in contact with the guide groove 4114. By engaging the rib 113 with the guide groove 4114, rotation of the first mounting unit 410 relative to the sensor 101 can be effectively prevented. Furthermore, the rib 113 and guide groove 4114 provide excellent positioning, improving the efficiency and accuracy of the assembly between the first mounting unit 410 and the sensor 101. Furthermore, the protruding rib 113 and the guide groove 4114 limit the installation position of the first mounting unit 410 relative to the sensor 101, ensuring that the first mounting unit 410 can only be inserted into the inner cavity 111 at a specific position. This ensures that the protruding rib 113 cooperates with the guide groove 4114, and also ensures that the fixing buckle 530 and the sliding buckle 520 cooperate with the locking hole 112. In other words, the cooperation between the protruding rib 113 and the guide groove 4114 can play a "foolproof" role. In other embodiments, the guide groove 4114 can be formed on the outer shell 110, and the protruding rib 113 can be provided on the base body 400.

[0066] This application also provides an electronic device including the detection device 10 described above. Since the detection device 10 is more convenient to use, the ease of use of the electronic device can be improved.
