[0086] The embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. Unless otherwise specified, the embodiments and technical features described in this disclosure can be combined with each other. The embodiments described with reference to the accompanying drawings are exemplary and intended to explain this disclosure, but should not be construed as limiting it.

[0087] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0088] Specific technical solutions will now be described in detail with reference to the accompanying drawings, which are not necessarily drawn to scale. Similar or identical reference numerals may be used to designate the same or similar parts in different figures. The use of similar or identical reference numerals in different figures does not imply that all figures including similar or identical reference numerals constitute a single or the same embodiment. The accompanying drawings illustrate the various embodiments discussed in this disclosure in a generalized, illustrative, and not restrictive manner.

[0089] In related technologies, cleaning robots suffer from poor obstacle detection, which affects obstacle avoidance and cleaning effectiveness.

[0090] The lifting detection device 100 and cleaning robot 1000 provided in the embodiments of the first aspect of this disclosure are intended to at least partially solve one of the technical problems in the related art.

[0091] As shown in Figures 1 to 8, this disclosure provides a lifting detection device 100, which can be used in self-propelled devices, including the cleaning robot shown in Figure 1. The lifting detection device 100 includes a base 1, a detection component (not shown), a drive component 3, a protective cover 8, a micro switch 11, and a trigger 12. The detection component is at least partially movably mounted on the base 1 in the vertical direction. The drive component 3 is mounted on the base 1 and connected to the detection component, used to drive the detection component to move. The protective cover 8 is rotatably connected to the detection component. One of the micro switch 11 and the trigger 12 is mounted on the protective cover, and the other is mounted on the detection component. When the protective cover 8 rotates to the point where the trigger 12 triggers the micro switch 11, the drive component 3 causes the detection component to descend.

[0092] In use, the lifting detection device 100 of this embodiment has a trigger 12 mounted on the protective cover 8 and a micro switch 11 mounted on the detection component. The micro switch 11 is connected to the drive component 3 for control. The detection component is used to acquire obstacle information. Specific types of the detection component may include cameras, millimeter-wave radar, lidar, infrared, and ultrasonic sensors.

[0093] When the cleaning robot 1000 is working, if the protective cover 8 touches a tall obstacle and is pressed down, the trigger 12 set between the protective cover 8 and the detection component will contact the micro switch 11. This contact action will trigger the micro switch 11, thereby sending a signal to the control system. After receiving the signal, the control system will instruct the drive component 3 to lower the detection component in order to reduce the height of the protective cover 8 to avoid obstacles.

[0094] The primary function of the protective cover 8 is to protect the detection components from physical damage or contamination, thereby extending their service life. By reducing the impact of the external environment on the detection components, the accuracy of detection and the reliability of the entire system can be improved. In harsh working environments, such as high temperature, high humidity, or dusty environments, the protective cover 8 can provide a relatively stable and clean working environment. The protective cover 8 can prevent operators or other objects from accidentally coming into contact with the detection components, reducing safety risks.

[0095] Therefore, when the cleaning robot 1000 equipped with the lifting detection device 100 of this embodiment encounters obstacles of different heights, the height of the detection component can be adjusted by the drive component 3 to identify and avoid the obstacles, thereby reducing the risk of collision and damage and improving the obstacle avoidance effect. The cleaning robot 1000 can also adjust the height of the detection component according to changes in the height of the obstacle to better adapt to the cleaning needs of different ground surfaces and improve the cleaning effect. Furthermore, the microswitch 11 and the trigger 12 enable automatic linkage between the protective cover 8 and the drive component 3, improving the automation level of the operation. The rapid response capability of the microswitch 11 ensures that a signal is triggered immediately when the protective cover 8 touches an obstacle, thereby adjusting the height position of the detection component in a timely manner. The lifting detection device 100 of this embodiment can significantly improve the obstacle avoidance ability and cleaning effect of the cleaning robot 1000.

[0096] The height-adjustable detection device 100 disclosed herein possesses low-altitude space adaptability. For example, by lowering its height (e.g., below the robot's main body), the height-adjustable detection device 100 can smoothly enter low-altitude areas (such as under beds or sofa crevices) that are inaccessible to fixed-height detection devices, thus improving cleaning efficiency. The height-adjustable detection device 100 also possesses complex terrain adaptability. For instance, when the robot encounters carpets, thresholds, or other objects with varying heights, the height of the detection device can be dynamically adjusted to optimize ranging accuracy and avoid misjudgments or missed areas. Furthermore, through its lifting function, the detection device can acquire environmental data from different height planes (such as under furniture or between table legs), constructing a more comprehensive 3D map and improving obstacle recognition capabilities.

[0097] In some embodiments, as shown in Figures 7 and 8, the lifting detection device 100 of this disclosure includes a slide 2, the slide 2 having a sliding portion 201, and a base 1 having a groove 101 extending in a vertical direction. The sliding portion 201 is slidably fitted into the groove 101 in a vertical direction. A driving assembly 3 is connected to the slide 2 to drive the slide 2 to slide. A detection assembly is disposed on the slide 2, and a protective cover 8 is rotatably connected to the slide 2 between a first position and a second position via a rotating shaft 9.

[0098] Specifically, the detection component is mounted on the slide block 2, and the drive component 3 drives the slide block 2 to rise or fall, which in turn drives the detection component to rise or fall, thereby realizing the lifting and lowering of the detection component. The sliding fit of the slide block 2 within the slide groove 101 provides good stability, ensuring that there will be no shaking or deviation during the lifting and lowering process.

[0099] In some embodiments, a first elastic element 10 is provided between the protective cover 8 and the slide 2 for resetting the protective cover 8 to a first position.

[0100] When the cleaning robot 1000 is working, if the protective cover 8 encounters a tall obstacle and is pressed downwards, the trigger 12 on the protective cover 8 will contact the micro switch 11 on the slide block 2 while the protective cover 8 is pressing against the first elastic element 10. This contact action will trigger the micro switch 11, thereby sending a signal to the control system. After receiving the signal, the control system will instruct the drive component 3 to lower the detection component, so as to reduce the height of the protective cover 8 to avoid the obstacle. After the obstacle avoidance is completed, the protective cover 8 will return to its initial position (i.e., the first position) under the elastic force of the first elastic element 10.

[0101] The rotatable design of the protective cover 8 allows it to be quickly opened when testing is needed and automatically reset when not testing, improving operational flexibility. Through the action of the first elastic element 10, the protective cover 8 can automatically return to the first position when not in use, reducing manual intervention. The reset mechanism of the first elastic element 10 ensures that the protective cover 8 always remains in the correct position, improving the reliability of the entire mechanism.

[0102] In some embodiments, the slide 101 is provided with a first stop 4 and a second stop 5. The first stop 4 is used to stop the sliding part 201 when the detection component rises to a first preset position, and the second stop 5 is used to stop the sliding part 201 when the detection component falls to a second preset position.

[0103] In some embodiments, as shown in Figures 7 and 8, the first stop 4 and the second stop 5 are vertically spaced on the sidewall of the slide groove 101, with the first stop 4 located above the second stop 5, and the sliding part 201 located between the first stop 4 and the second stop 5.

[0104] The first stop 4 stops the sliding part 201 when the detection component rises to the first preset position, preventing it from continuing to rise. The second stop 5 stops the sliding part 201 when the detection component descends to the second preset position, preventing it from continuing to descend. The first stop 4 and the second stop 5 limit the movement range of the detection component to ensure that the detection component is accurately positioned at a specific working height and to ensure that the detection component is not damaged due to exceeding the design range. When the detection component reaches the preset upper or lower limit, the stop can prevent it from continuing to move, avoiding damage to the equipment.

[0105] In some embodiments, the drive assembly 3 includes a first link 301, a second link 302 and a motor 303. The first end of the first link 301 is connected to the motor 303, the second end of the first link 301 is pivotally connected to the first end of the second link 302, and the second end of the second link 302 is pivotally connected to the slide 2.

[0106] As shown in Figures 6 to 8, after the motor 303 starts, it drives the first link 301 to rotate through rotational motion. The pivotal connection between the first link 301 and the second link 302 allows for changes in the angle between the two links, thereby transmitting motion. The pivotal connection between the second link 302 and the slide 2 allows the slide 2 to rise or fall as the angle of the linkage mechanism changes.

[0107] The linkage mechanism enables smooth lifting and lowering movements, preventing vibration of the slide 2 during operation. Through the cooperation of the motor 303 and the linkage, the lifting position of the slide 2 can be precisely controlled to meet the working requirements at different heights. The linkage mechanism has a relatively compact design, saving space and making it suitable for use in confined spaces.

[0108] In some embodiments, the side wall of the slide 101 is provided with a through hole, the first connecting rod 301 and the second connecting rod 302 are provided in the slide 101, the motor 303 is provided outside the slide 101 and the motor 303 shaft of the motor 303 passes through the through hole and extends into the slide 101 to be connected with the first connecting rod 301.

[0109] External mounting of the motor 303 allows for a more compact internal space within the slide rail 101, providing more room for other components or functional modules. This makes maintenance and replacement of the motor 303 easier and faster, and also protects the motor 303 from the effects of the internal environment of the slide rail 101 (such as dust and moisture), thus extending its service life. Furthermore, the motor 303 generates heat during operation, and placing it externally within the slide rail 101 helps with heat dissipation.

[0110] In some embodiments, the slide 2 has an upper chamber 202 and a lower chamber 203, with at least a portion of the detection component located in the upper chamber 202 and at least a portion of the second link 302 located in the lower chamber 203.

[0111] In other words, the upper chamber 202 of the slide 2 is used to accommodate part or all of the detection assembly. The lower chamber 203 of the slide 2 is used to accommodate part or all of the second connecting rod 302.

[0112] As shown in Figures 7 and 8, a modular design is achieved by placing the detection component and the linkage mechanism in separate chambers, facilitating maintenance and replacement. Placing the detection component in the upper chamber 202 provides additional protection against damage during lifting and lowering. The arrangement of the upper chamber 202 and lower chamber 203 helps improve the stability and balance of the entire slide 2, especially during lifting and lowering. The design of the upper chamber 202 and lower chamber 203 provides dustproof and waterproof protection for the internal electronic components, improving their reliability in harsh environments. Furthermore, separating the detection component and the linkage mechanism reduces mutual interference between them, such as electromagnetic interference or mechanical vibration.

[0113] In some embodiments, the drive assembly 3 further includes a second elastic element 304 and a connecting seat 305. The second elastic element 304 and the connecting seat 305 are disposed in the lower chamber 203. The second elastic element 304 is located between the connecting seat 305 and the top wall of the lower chamber 203. The second end of the second connecting rod 302 is pivotally connected to the connecting seat 305. The second elastic element 304 is used to apply an upward elastic force to the slide 2 when the detection assembly rises to the first preset position.

[0114] Specifically, as shown in Figures 6 to 8, when the drive component 3 raises the detection component to the first preset position, the second elastic element 304 applies an upward elastic force to the slide 2. On the one hand, when the detection component or the slide 2 collides with an obstacle during the movement of the cleaning robot 1000, the second elastic element 304 can be compressed, playing a buffering role and effectively protecting the detection component from damage. On the other hand, the elastic properties of the second elastic element 304 can absorb and buffer the impact and vibration that may be generated during the lifting process, achieving a smoother lifting.

[0115] In some embodiments, the top of the connecting seat 305 has a cylindrical boss 6, and the second elastic member 304 is a spring with its lower end sleeved on the cylindrical boss 6.

[0116] In some embodiments, as shown in FIG6, the cylindrical boss 6 provides a positioning and guiding mechanism for the second elastic member 304, ensuring that the second elastic member 304 is correctly installed in a predetermined position and avoiding offset or tilting. Additionally, the cylindrical boss 6 ensures that the force on the second elastic member 304 is evenly distributed when subjected to compression or tension.

[0117] In some embodiments, there are multiple second elastic members 304 arranged at circumferential intervals along the connecting seat 305.

[0118] As shown in Figure 6, the evenly arranged multiple second elastic elements 304 ensure a more uniform elastic force on the slide block 2, thereby reducing structural deformation or damage caused by uneven elastic force. The uniform distribution of springs helps enhance the stability of the entire lifting mechanism, better resisting external disturbances during lifting. The spaced arrangement of multiple springs reduces the pressure on a single spring, avoiding spring fatigue or damage caused by localized stress concentration.

[0119] In some embodiments, as shown in FIG6, the connecting seat 305 includes a first seat body 3051 and a second seat body 3052. The first seat body 3051 has a first pivot hole, the second seat body 3052 has a second pivot hole, and the second end of the second connecting rod 302 is provided with a pivot 7. The first end of the pivot 7 is pivotally engaged in the first pivot 7 hole, and the second end of the pivot 7 is pivotally engaged in the second pivot 7 hole.

[0120] By dividing the connector 305 into a first seat body 3051 and a second seat body 3052 and connecting them via a pivot 7, it can adapt to different installation environments, making the connector 305 easy to install. This, in turn, makes the installation and maintenance of the connector 305 more convenient, allowing for quick assembly and disassembly. The pivoting connection of the pivot 7 provides a stable support point, ensuring the reliability and long-term stability of the connector 305.

[0121] In some embodiments, one of the trigger 12 and the micro switch 11 is located on the side of the outer periphery of the protective cover 8 away from the rotation shaft 9.

[0122] It is understood that the rotating shaft 9 is located on one side of the protective cover 8, and the trigger 12 and the micro switch 11 are located on the other side of the protective cover 8. Referring to Figure 4, the rotating shaft 9 is located on the left side of the protective cover 8, and one of the trigger 12 and the micro switch 11 is located on the right side of the protective cover 8. The left and right directions here refer to the left and right directions in the drawing.

[0123] In some embodiments, on the side of the outer periphery of the protective cover 8 away from the rotation axis 9, one of the trigger 12 and the micro switch 11 is disposed opposite to the first elastic member 10.

[0124] As can be understood, referring to Figure 4, on the right side of the protective cover 8, one of the trigger 12 and the micro switch 11 is positioned opposite the first elastic member 10 in the front-back direction. Here, the front-back direction refers to the front-back direction in the drawing.

[0125] In some embodiments, two first elastic elements 10 may be provided, with one of the trigger element 12 and the micro switch 11 located between the two first elastic elements 10.

[0126] In some embodiments, the slide block 2 further includes a guide structure 14, which includes a first limiting part 141, a guide part 142, and a second limiting part 143. The guide part 142 passes through the protective cover 8 and is connected to the first limiting part 141. The second limiting part 143 is disposed above the slide block 201 and is connected to the end of the guide part 142 away from the first limiting part 141. The first elastic member 10 is sleeved on the guide part 142 and abuts against the second limiting part 143.

[0127] In some embodiments, the diameter of the guide portion 142 is smaller than the diameter of the first limiting portion 141 and the diameter of the second limiting portion 143.

[0128] In some embodiments, the protective cover 8 is connected to the first support base, the slide 2 is connected to the second support base 151, the first support base has a first hole, the second support base 151 has a second hole, and the rotating shaft 9 is rotatably disposed in the first hole and the second hole.

[0129] The rotating shaft 9 is clearance-fitted with the first hole and the second hole.

[0130] In some embodiments, one of the protective cover 8 and the slide 2 is provided with an elastic buckle, and the other is provided with a slot. The slot is an adapter structure for the elastic buckle, and the elastic buckle can be locked in the slot. The width of the slot is greater than the thickness of the elastic buckle along the axial direction of the protective cover.

[0131] The cooperation relationship between the protective cover 8 and the slide 2 in the first aspect embodiment of this disclosure can be referred to the cooperation relationship between the cover 220 and the base 210 in the second aspect embodiment below.

[0132] In some embodiments, the protective cover 8 includes a light-transmitting sleeve, a cover, and a base, with the cover connected to the light-transmitting sleeve; the base is connected to the end of the light-transmitting sleeve away from the cover; wherein the working surface of the light-transmitting sleeve is an integral surface without weld lines.

[0133] In some embodiments, the light-transmitting sleeve, cover, and base are integrally formed.

[0134] In some embodiments, the light-transmitting sleeve, cover, and base are made of the same light-transmitting material.

[0135] In some embodiments, the cover has a mounting groove, and the bottom of the mounting groove has a through hole that communicates with the interior of the light-transmitting sleeve.

[0136] The protective cover 8 can be an embodiment of the light-transmitting cover 340 described below, and the fabrication module of the light-transmitting cover 340 is also suitable for fabricating the protective cover 8 in the first aspect embodiment of this disclosure.

[0137] In some embodiments, the protective cover 8 of the first aspect embodiment of this disclosure can adopt the cover 220 of the second aspect embodiment; the cooperation relationship between the micro switch 11 and the trigger 12 of the first aspect embodiment can also adopt the cooperation relationship between the detection element 241 and the trigger 242 in the trigger assembly 240 of the second aspect embodiment; the guide structure 14 of the first aspect embodiment can also adopt the structure of the guide 260 of the second aspect embodiment; the installation method of the rotating shaft 9 in the first aspect embodiment can also refer to the installation method of the rotating element 230 in the second aspect embodiment.

[0138] The cleaning robot 1000 of this embodiment includes a housing 13 and a lifting detection device 100. The top surface of the housing 13 has a first opening, and the lifting detection device 100 is the lifting detection device 100 in any of the above embodiments. The base 1 is disposed inside the housing 13. At least a portion of the detection component can be raised to the outside of the housing 13 through the first opening, and at least a portion of the detection component can be lowered to the top surface of the housing 13 through the first opening.

[0139] In use, the cleaning robot 1000 of this embodiment allows the detection component to be raised and lowered via the drive component 3, extending outwards through the first opening on the top surface of the housing 13 and descending inwards. When the cleaning robot 1000 encounters obstacles of varying heights, the drive component 3 can adjust the height of the detection component to identify and avoid obstacles, thereby reducing the risk of collisions and damage and improving obstacle avoidance. Furthermore, the cleaning robot 1000 can adjust the height of the detection component according to changes in obstacle height to better adapt to the cleaning needs of different surfaces and improve cleaning effectiveness. Therefore, the cleaning robot 1000 of this embodiment possesses the advantages of both obstacle avoidance capability and excellent cleaning performance.

[0140] In some embodiments, the sidewall of the housing 13 is provided with a second opening 1301, through which the detection component can transmit a detection signal when it is located inside the housing 13.

[0141] When the detection component does not need to be raised for detection, it can remain inside the housing 13. In this case, the detection component can emit detection signals through the second opening 1301 on the side wall of the housing 13. These signals can be used to detect the surrounding environment, such as measuring distance, detecting obstacles, and identifying clean areas, enhancing the robot's perception capabilities. The fact that the detection component can still perform detection while inside optimizes the use of internal space, making the robot's design more compact.

[0142] As an advanced high-precision measurement method, lidar emits a laser beam and receives the reflected beam, accurately calculates the round-trip time of the beam, and then determines the distance between the target object and the lidar. It has significant advantages such as high measurement accuracy, fast response speed, and strong anti-interference ability.

[0143] In related technologies, during the use of lidar, if the electrical equipment on which the lidar is installed does not have the function of low-profile detection, or if it fails to detect low-profile spaces, the lidar will not descend, causing the electrical equipment to get stuck and unable to move.

[0144] Based on these technical problems, this disclosure provides a detection module and electrical equipment, which aims to solve, to at least some extent, the technical problem that electrical equipment is stuck and unable to move normally when entering low-ceilinged spaces because the lidar has not descended.

[0145] The design concept of the second aspect of this disclosure is that: the rotating member rotatably connects the cover and the base, so that the cover can rotate relative to the base under the action of forces in multiple directions, thereby achieving the technical effect of detection at a larger angle.

[0146] Referring to Figures 9, 10, and 11, the detection module of this embodiment includes: a base 210, a cover 220, a rotating member 230, and a trigger assembly 240. The cover 220 is disposed on the base 210. The rotating member 230 rotatably connects the cover 220 and the base 210, allowing the cover 220 to rotate relative to the base 210 in multiple directions. The trigger assembly 240 includes a detection member 241 and a trigger member 242. The trigger member 242 has a trigger portion 2422 for triggering the detection member 241. One of the trigger member 242 and the detection member 241 is disposed on the base 210, and the other is disposed on the cover 220. The trigger portion 2422 and the detection member 241 form a pressing engagement to trigger a detection signal. In some embodiments, the trigger member 242 can be a pressure plate with protrusions, which can be configured as the trigger portion 2422. The detection member 241 can be a button.

[0147] In some embodiments, the detection element 241 in the second aspect of this disclosure may be the micro switch 11 in the first aspect.

[0148] Since the cover 220 is located on the base 210, the rotating member 230 rotatably connects the cover 220 and the base 210, so that the cover 220 can rotate relative to the base 210. The triggering component 240 includes a detection member 241 and a triggering member 242. The triggering member 242 is provided with a triggering part 2422 for triggering the detection member 241. One of the triggering member 242 and the detection member 241 is located on the base 210, and the other is located on the cover 220. Therefore, when the electrical equipment travels, if it reaches a low-ceilinged space, the obstacle will collide with the cover 220, and the obstacle will exert a force on the cover 220. Since the shape and collision angle of the obstacle are uncertain, the cover 220 may be subjected to forces in multiple directions around its circumference. Under the action of these multiple forces, each direction can be decomposed into a force that drives the rotating component 230 to rotate around its axis. This allows the cover 220 to rotate relative to the base 210 via the rotating component 230, achieving adaptive rotation of the cover 220 to the forces in multiple directions. During the rotation of the cover 220, the cover... The cover 220 tilts on the base 210. The cover 220 drives one of the trigger element 242 and the detection element 241 to move, causing the trigger element 2422 to press against the detection element 241 to trigger a detection signal. This enables detection over a wider range, i.e., detection at a greater angle. The detection element 241 sends the detection signal to the controller of the electrical equipment. The controller, based on the detection signal, controls the base 210 to descend above the main body of the electrical equipment, ensuring that the height of the cover 220 is lower than the height of any obstacle, preventing collisions and ensuring the normal operation of the electrical equipment. Furthermore, only one trigger element 240 is needed to achieve detection at a greater angle, eliminating the need to increase the number of trigger elements 240, thus reducing costs. Simultaneously, the structural space of the detection module can be reduced, facilitating miniaturization of the detection module. The trigger element has a trigger part for triggering the detection element, which presses against the detection element to trigger the detection signal.

[0149] When the electrical equipment is located in a low-ceilinged space, the base 210 rises on the main body of the electrical equipment, and the top of the cover 220 collides with an obstacle. The obstacle exerts a force on the top of the cover 220. Since the cover 220 can rotate relative to the base 210 under forces from multiple directions, the cover 220 can rotate on the base 210 via the rotating member 230. During the rotation of the cover 220, the cover 220 tilts on the base 210, causing one of the trigger member 242 and the detection member 241 to move, so that the trigger member 2422 and the detection member 241 form a pressing engagement to trigger a detection signal, realizing top triggering. The detection member 241 sends the detection signal to the controller of the electrical equipment. The controller controls the base 210 to descend on the main body of the electrical equipment according to the detection signal, so that the height of the cover 220 no longer contacts the obstacle, avoiding the cover 220 from being stuck, and ensuring the normal operation of the main body of the electrical equipment.

[0150] In some embodiments, the trigger 242 can be disposed on the cover 220, and the detection element 241 can be disposed on the base 210. The detection element 241 can be fastened to the base 210 to improve installation efficiency. Of course, in some other embodiments, the detection element 241 can be disposed on the cover 220, and the trigger 242 can be disposed on the base 210.

[0151] Referring to Figures 9, 10, and 11, in some embodiments, in order to ensure that the cover 220 can rotate smoothly relative to the base 210, the trigger component 240 and the rotating component 230 are staggered, so that the trigger component 240 and the rotating component 230 are spatially independent of each other, so as to avoid interference between the trigger component 240 and the rotating component 230, providing sufficient space for the rotation of the cover 220, ensuring that the cover 220 can rotate freely and smoothly along the axis around the rotation shaft 233, without being restricted by interference between components.

[0152] The trigger component 240 and the rotating component 230 are offset from each other. This can be understood as the trigger component 240 and the rotating component 230 being offset from each other on the outer periphery of the cover 220, and their positions on the outer periphery of the cover 220 not coinciding.

[0153] In some embodiments, when the cover 220 is cylindrical, the rotating member 230 and the triggering assembly 240 are located in different radial directions of the cover 220. When the cover 220 is cuboid, the rotating member 230 and the triggering assembly 240 are located on opposite sides of the cover 220.

[0154] Referring to Figures 12, 13, and 14, in some embodiments, to enable the cover 220 to rotate relative to the base 210 under forces in multiple directions, the rotating component 230 includes: a first support 231, a second support 232, and a rotating shaft 233. The first support 231 is connected to the base 210 and has a first hole 2311. The second support 232 is connected to the cover 220 and has a second hole 2321. The rotating shaft 233 is rotatably disposed in the first hole 2311 and the second hole 2321. The rotating shaft 233 is clearance-fitted with the first hole 2311 and the second hole 2321. In some embodiments, the first hole 2311 and the second hole 2321 are coaxially arranged.

[0155] When the cover 220 is subjected to an external force, the force is transmitted to the second support 232. The second support 232 drives the rotating shaft 233 to rotate within the first hole 2311 and the second hole 2321, enabling the cover 220 to rotate relative to the base 210 around the axis of the rotating shaft 233. Since the rotating shaft 233 is clearance-fitted with the first hole 2311 and the second hole 2321, it can be understood that the rotating shaft 233 is not tightly fitted to the hole walls of the first hole 2311 and the second hole 2321, and there is a certain amount of room for movement. When the cover 220 is subjected to external forces in different directions, and the external force has a component perpendicular to the axis of the rotating shaft 233, the rotating shaft 233 can shift or swing within this space, thereby enabling the cover 220 to rotate around the axis of the rotating shaft 233, rather than being limited to rotation around the axis of the rotating shaft 233, thus enabling detection at a larger angle.

[0156] In some embodiments, the gap between the rotating shaft 233 and the wall of the first hole 2311 and the wall of the second hole 2321 is greater than or equal to the distance between the initial position of the trigger part 2422 and the detection element 241 to trigger a pressing engagement to trigger the detection signal. In some embodiments, the initial position is the position of the trigger part 2422 when the cover 220 does not collide with an obstacle.

[0157] Referring to Figure 15, in some embodiments, to ensure the stability of the rotating shaft 233 during rotation, the first support base 231 includes a first support portion 2312 and a second support portion 2313. Along the axial direction of the rotating shaft 233, the first support portion 2312 and the second support portion 2313 are spaced apart on the base 210. The second support base 232 is located between the first support portion 2312 and the second support portion 2313. The rotating shaft 233 passes sequentially through the first support portion 2312, the second support base 232, and the second support portion 2313, allowing the first support portion 2312 and the second support portion 2313 to support different positions of the rotating shaft 233, increasing the number of support points and improving the stability of the rotating shaft 233's movement.

[0158] Referring to Figures 16 and 17, in some embodiments, to enable the housing 220 to reset, the detection module further includes a reset mechanism. The reset mechanism includes at least two elastic reset members 250. The elastic reset members 250 are disposed between the base 210 and the trigger member 242. The detection member 241 is located between the two elastic reset members 250. In some embodiments, the elastic reset members 250 can be springs.

[0159] Because the two elastic reset members 250 are spaced apart, and the detection member 241 is located between the two elastic reset members 250, when the cover 220 rotates relative to the base 210 via the rotating member 230, the cover 220 applies pressure to the elastic reset members 250, causing at least one of the two elastic reset members 250 to be compressed. After the base 210 descends onto the main body of the electrical equipment, the obstacle no longer exerts a force on the cover 220. At this time, under the action of the elastic restoring force of the compressed elastic reset members 250, the elastic reset members 250 extend, pushing the cover 220 to rotate on the base 210, so that the cover 220 returns to its original position.

[0160] Referring to Figure 16, in some embodiments, two elastic reset members 250 are arranged axially along the rotating member 230, ensuring that at least one of the two elastic reset members 250 is compressed when the cover 220 rotates relative to the base 210 via the rotating member 230. In some embodiments, when there are two elastic reset members 250, the two elastic reset members 250 are symmetrical about the center line of the detection member 241 as an axis of symmetry, and the radial center line of the detection member 241 extends radially along the cover 220.

[0161] Referring to Figures 17, 18, and 19, in some embodiments, to guide the movement of the elastic reset member 250, the detection module further includes a guide member 260 corresponding to the elastic reset member 250. The guide member 260 includes a first limiting portion 261, a guide portion 262, and a second limiting portion 263. The guide portion 262 passes through the trigger member 242 and connects to the first limiting portion 261. The second limiting portion 263 is fixedly disposed on the base 210 and connected to the end of the guide portion 262 away from the first limiting portion 261. The elastic reset member 250 is sleeved on the guide portion 262 and the second limiting portion 263, and the compression and extension movements of the elastic reset member 250 are guided by the guide portion 262 and the second limiting portion 263, ensuring the stability of the movement of the elastic reset member 250.

[0162] In some embodiments, there are multiple elastic reset members 250 and multiple guide members 260, with each guide member 260 corresponding to one of the multiple elastic reset members 250, and the elastic reset member 250 being sleeved on the corresponding guide member 260.

[0163] Referring to Figures 17, 19, and 20, in some embodiments, to achieve limiting, the trigger member 242 has a through hole 2421 through which the guide portion 262 passes. The diameter of the through hole 2421 is smaller than the diameter of the first limiting portion 261 and the second limiting portion 263. When the elastic reset member 250 is compressed, the trigger member 242 moves towards the base 210 to allow the cover 220 to rotate on the base 210. When the trigger member 242 abuts against the second limiting portion 263, the second limiting portion 263 blocks the trigger member 242 from moving towards the base 210, thus achieving limiting and preventing the trigger member 242 from damaging the detection member 241, ensuring the safety of the detection member 241. When the elastic reset member 250 extends, the trigger member 242 moves away from the base 210 to realize the rotation of the cover 220 on the base 210. When the trigger member 242 comes into contact with the first limiting part 261, the first limiting part 261 blocks the trigger member 242 from moving towards the base 210, thus achieving the limiting and preventing the trigger member 242 from detaching from the guide part 262, ensuring the stability of the trigger member 242's movement.

[0164] Referring to Figures 17, 19 and 20, in some embodiments, the diameter of the through hole 2421 is greater than or equal to the diameter of the guide portion 262, so that the guide portion 262 can move smoothly within the through hole 2421 and avoid interfering with the rotation of the cover 220 on the base 210.

[0165] In some embodiments, for ease of installation, the first limiting part 261 can be a bolt, with the bolt threadedly connected to the guide part 262. When the elastic reset member 250 needs to be installed, the bolt can be threadedly connected to the guide part 262. The diameter of the through hole is smaller than the diameter of the nut on the bolt to achieve limiting.

[0166] Referring to Figures 21, 22, and 23, in some embodiments, to enable the cover 220 to be mounted on the base 210, one of the cover 220 and the base 210 is provided with an elastic buckle 211, and the other is provided with a slot 221. The slot 221 is an adaptation structure for the elastic buckle 211, and the elastic buckle 211 can be engaged in the slot 221. Along the axial direction of the cover 220, the width of the slot 221 is greater than the thickness of the elastic buckle 211, allowing the elastic buckle 211 to move slightly axially or undergo elastic deformation within the slot 221, thereby reserving space for multi-directional rotation of the cover 220.

[0167] When the cover 220 is to be installed on the base 210, the elastic buckle 211 is snapped into the slot 221, which can realize the installation of the cover 220 on the base 210, reducing the installation difficulty and improving the installation efficiency.

[0168] Since the width of the slot 221 is greater than the thickness of the elastic buckle 211 and is elastic, the elastic buckle 211 can move within the slot 221 when the cover 220 rotates relative to the base 210, or the elastic buckle 211 will deform to avoid interfering with the rotation of the cover 220 relative to the base 210 and ensure that the cover 220 moves smoothly.

[0169] In some embodiments, the base 210 may be provided with an elastic buckle 211, and the cover 220 may be provided with a slot 221. Of course, in some other embodiments, the cover 220 may be provided with an elastic buckle 211, and the base 210 may be provided with a slot 221.

[0170] Referring to Figure 24, in some embodiments, to avoid interference with the rotation of the cover 220 relative to the base 210, the base 210 includes a support portion 212 and a receiving portion 213 connected to the support portion 212. The cover 220 includes a cylindrical body 222 and a cover 223. The cylindrical body 222 is rotatably disposed on the support portion 212 and is sleeved on the outside of the receiving portion 213. The cover 223 is disposed at the end of the cylindrical body 222 away from the support portion 212, forming a protective cavity with the cylindrical body 222. The inner wall of the cylindrical body 222 is spaced apart from the outer wall of the receiving portion 213, providing sufficient room for rotation of the cylindrical body 222. This ensures that the cylindrical body 222 will not contact or collide with the receiving portion 213 during rotation relative to the base 210, thereby avoiding interference and ensuring smooth rotation of the cylindrical body 222.

[0171] In some embodiments, the detection module includes a rangefinder, which is mounted on the base 210 and located within the protective cavity of the housing 220. The base 210 and housing 220 protect the rangefinder, preventing dust, moisture, and other impurities from entering it and ensuring its safety. In some embodiments, the rangefinder can be an LDS (laser distance sensor).

[0172] The enclosure 220 has a rotatable mirror inside. The rotating mirror can project the light emitted by the rangefinder's transmitting module through the circumference of the enclosure 220, so that the light emitted by the transmitting module can be used for distance measurement, achieving 360° distance measurement. Therefore, the enclosure 220 needs to extend beyond the main body of the electrical equipment.

[0173] Based on the same inventive concept, this disclosure also proposes an electrical device that uses the aforementioned detection module. The specific structure of the detection module is as described in the above embodiments. Since the detection module uses all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0174] In some embodiments, the electrical device includes a main body. A base for the detection module is disposed on the main body. In some embodiments, the base of the detection module can be raised and lowered on the main body.

[0175] In some embodiments, in order to ensure that the cover 220 can rotate smoothly relative to the base 210, the rotating member 230 is located in front of the triggering component 240 along the moving direction of the main body, so that the triggering component 240 and the rotating member 230 are spatially independent of each other, so as to avoid interference between the triggering component 240 and the rotating member 230, providing sufficient space for the rotation of the cover 220, ensuring that the cover 220 can rotate freely and smoothly around the axis of the rotating shaft 233, and will not be restricted by interference between components.

[0176] LiDAR systems require a light-transmitting cover to protect internal optical components from dust, moisture, and other impurities, while also ensuring the laser beam can pass smoothly through for transmission and reception. However, in related technologies, the light-transmitting cover often has welded lines, which affect the optical performance of the LiDAR.

[0177] In related technologies, light-transmitting covers are generally manufactured using injection molding. During injection molding, molten material enters the mold cavity from the gate and flows forward along different paths. When two or more streams of molten material meet in the cavity, differences in temperature, pressure, and other conditions at the leading edge of the molten material prevent them from completely fusing together, resulting in a noticeable linear mark at the meeting point, known as a weld line. The presence of weld lines has several adverse effects on the performance of the light-transmitting cover. From an optical performance perspective, weld lines disrupt the smoothness and uniformity of the light-transmitting cover surface, causing light to scatter and refract as it passes through, reducing light transmittance and affecting the signal transmission and measurement accuracy of the lidar.

[0178] Based on these technical problems, the third aspect of this disclosure provides a light-transmitting cover, a light-transmitting cover manufacturing module, a ranging device, and an electrical device, aiming to solve the technical problem that the light-transmitting cover has weld lines, which affect the optical performance of the lidar.

[0179] The design concept of the third aspect of this disclosure is that: the top of the outer mold is provided with a glue injection port so that the molten material enters the cavity from top to bottom, avoiding the formation of multiple strands of molten material, thereby achieving the technical effect of a weld line-free light-transmitting cover.

[0180] Referring to Figures 25 and 26, the light-transmitting cover 340 of an embodiment of the third aspect of this disclosure includes: a light-transmitting sleeve 341, a cover 342, and a base 343. The cover 342 is connected to the light-transmitting sleeve 341. The base 343 is connected to the end of the light-transmitting sleeve 341 away from the cover 342. The working surface of the light-transmitting sleeve 341 is a one-piece surface without weld lines.

[0181] Since the working surface of the light-transmitting sleeve 341 is a one-piece surface without weld lines, the working surface of the light-transmitting sleeve 341 is continuous and without breaks, ensuring the consistency of the working surface of the light-transmitting sleeve 341. This allows light to pass through the light-transmitting sleeve 341 more smoothly, thereby significantly improving the light transmittance. The light propagation path through the light-transmitting sleeve 341 is more stable and regular, which is beneficial to the signal transmission of the rangefinder and ensures the measurement accuracy of the rangefinder.

[0182] In related technologies, the cover, the light-transmitting sleeve, and the base are three independent parts that need to be manufactured separately. Then, in the subsequent assembly process, the cover, the light-transmitting sleeve, and the base are assembled one by one using specific processes and tools. This not only increases the assembly time and labor costs but also makes it easy for assembly errors to occur, such as parts not being installed in place or being in the wrong orientation.

[0183] In some embodiments, the light-transmitting sleeve 341, cover 342 and base 343 are integrally formed, integrating the light-transmitting sleeve 341, cover 342 and base 343 into a whole, eliminating the step-by-step assembly process, simplifying the installation process and improving production efficiency.

[0184] The assembly of split parts often requires the use of various specialized assembly equipment, such as assembly fixtures, positioning tools, and fastening devices. The purchase, maintenance, and replacement of this equipment all require significant financial investment. However, the light-transmitting sleeve 341, cover 342, and base 343 are integrally molded, eliminating the need for complex specialized assembly equipment and thus saving on equipment procurement and operating costs.

[0185] In molding processes such as injection molding and die casting, each part requires a separate mold for production. A split design for the cover, light-transmitting sleeve, and base requires three separate sets of molds, which not only increases the design and manufacturing difficulty of the molds but also raises their cost. However, by molding the light-transmitting sleeve 341, cover 342, and base 343 as a single piece, only one mold is needed to complete the molding of the entire light-transmitting cover 340, reducing the number of molds and their cost.

[0186] The integrated design of the light-transmitting sleeve 341, cover 342, and base 343 simplifies the production process, reduces assembly steps, significantly shortens the production cycle, and improves production efficiency. Simultaneously, by reducing potential errors and defects during assembly, the yield rate of the light-transmitting cover 340 is significantly improved, ensuring stable quality and performance, reducing scrap and rework rates, and further lowering production costs.

[0187] Different materials possess different physical and chemical properties, such as melting point, flowability, and shrinkage rate. If the light-transmitting sleeve, cover, and base are made of different materials, the mold design must consider the characteristics of each material individually to create a mold structure suitable for its molding, which increases the complexity and difficulty of the mold design. In some embodiments, to facilitate the fabrication of the light-transmitting cover 340, the light-transmitting sleeve 341, cover 342, and base 343 are made of the same light-transmitting material. This allows the mold design to be optimized based on the uniform characteristics of the light-transmitting material, resulting in a simpler and more rational mold structure and reducing the difficulty and cost of mold manufacturing. In some embodiments, the light-transmitting material can be PMMA (polymethyl methacrylate), PC (polycarbonate), GPPS (general-purpose polystyrene), etc.

[0188] Furthermore, since the light-transmitting sleeve 341, cover 342, and base 343 are made of the same light-transmitting material, the molding process parameters (such as temperature, pressure, and time) for the same light-transmitting material are relatively fixed. Therefore, there is no need to frequently adjust equipment parameters during production to adapt to the molding requirements of different materials. This makes the production process more stable and continuous, reducing production interruptions and downtime caused by material changes or parameter adjustments, thereby improving production efficiency.

[0189] Referring to Figures 25 and 26, in some embodiments, the base 343 is located outside the light-transmitting sleeve 341. Along the radial direction of the light-transmitting sleeve 341, the base 343 extends away from the light-transmitting sleeve 341, so that the base 343 can be installed on external equipment and avoid interference from external equipment with the operation of the rangefinder inside the light-transmitting sleeve 341.

[0190] Referring to Figures 25 and 26, in some embodiments, in order to facilitate the installation of other components on the cover 342, the cover 342 is provided with a mounting groove 3421, and the bottom of the mounting groove 3421 is provided with a through hole 3422 communicating with the interior of the light-transmitting sleeve 341. Components can be installed in the mounting groove 3421.

[0191] In some embodiments, to improve the aesthetics of the light-transmitting cover 340, the light-transmitting cover 340 further includes a decorative element. The decorative element is installed in a mounting groove 3421 and covers the through hole 3422. The mounting groove 3421 is used to accommodate the decorative element for easy installation and fixation. Light from the light-transmitting sleeve 341 can shine onto the decorative element through the through hole 3422, enhancing its aesthetics.

[0192] In some embodiments, the cover 342 is processed by laser cutting, punching, CNC (Computer Numerical Control) or other methods to create an mounting groove 3421 on the cover 342.

[0193] Referring to Figures 25 and 26, in some embodiments, in order to facilitate the connection of the cover 342 with external devices, the cover 342 has a connection hole 3423, which is used to connect and fix the light-transmitting cover 340 with the external devices, so as to facilitate the installation of the light-transmitting cover 340.

[0194] The connecting hole 3423 can be integrally formed during the injection molding of the light-transmitting cover 340, eliminating the need for subsequent drilling and improving production efficiency.

[0195] Based on the same inventive concept, this disclosure also proposes a ranging device that uses the aforementioned light-transmitting cover. The specific structure of the light-transmitting cover is as described in the above embodiments. Since the light-transmitting cover uses all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0196] In some embodiments, the ranging device includes a rangefinder, which is disposed inside the light-transmitting sleeve 341 of the light-transmitting cover 340. The light-transmitting sleeve 341 protects the rangefinder and prevents impurities such as dust and moisture from entering the rangefinder, thus ensuring the safety of the rangefinder.

[0197] In some embodiments, the rangefinder may be an LDS (laser distance sensor).

[0198] Based on the same inventive concept, this disclosure also proposes an electrical device that uses the aforementioned ranging device. The specific structure of the ranging device is as described in the above embodiments. Since the ranging device uses all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated here.

[0199] In some embodiments, the electrical device includes a body. A ranging device is disposed on the body.

[0200] In some embodiments, the electrical equipment may be a robotic vacuum cleaner, a drone, a car, etc.

[0201] Referring to Figures 25, 27, and 28, and based on the same inventive concept, this disclosure also proposes a light-transmitting cover fabrication module comprising an outer mold 310 and an inner mold 320. The inner mold 320 is disposed within the outer mold 310, and the inner mold 320 and the outer mold 310 are spaced apart to form a cavity 330. The top of the outer mold 310 has an injection port 311 communicating with the cavity 330. The injection port 311 is positioned such that after molten material is injected through it, a light-transmitting sleeve 341 without weld lines can be formed.

[0202] Since the inner mold 320 is located inside the outer mold 310, and the inner mold 320 and the outer mold 310 are spaced apart to form a cavity 330, the top of the outer mold 310 has a glue injection port 311 that communicates with the cavity 330. The position of the glue injection port 311 is set so that after the molten material is injected through it, a light-transmitting sleeve 341 without weld lines can be formed. Therefore, when preparing the light-transmitting cover 340, the molten material is injected into the cavity 330 through the glue injection port 311 at the top of the outer mold 310. Under the action of gravity, the molten material will flow downward in a relatively unidirectional direction to fill the cavity 330, making the flow path of the molten material in the cavity 330 relatively simple and orderly, reducing the chance of multiple molten materials merging with each other, reducing the possibility of weld lines. Moreover, the molten material flows smoothly along the main contour of the cavity 330, reducing the phenomenon of molten material diversion and re-merging caused by the complex structure of the cavity 330, further reducing the probability of weld lines.

[0203] Meanwhile, the molten material injected through the injection port 311 at the top of the outer mold 310 exhibits a more uniform temperature distribution during the filling of the cavity 330. This is because the heat dissipation of the molten material after entering the cavity 330 is relatively consistent, preventing excessive local temperature differences. Furthermore, the molten material with a uniform temperature has similar molecular activity during flow and filling, making it easier for them to fuse together and preventing the formation of weld lines due to insufficient fusion caused by temperature differences.

[0204] The molten material injected from the injection port 311 at the top of the outer mold 310 fills the cavity 330 with relatively uniform pressure distribution. As the molten material is continuously injected, the pressure can be transmitted relatively smoothly to all parts of the cavity 330. This uniform pressure distribution allows the leading edges of the molten material to fuse with relatively consistent pressure when they meet, which helps to improve the fusion quality and reduce the formation of weld lines.

[0205] After the molten material is formed in the cavity 330, a light-transmitting cover 340 is obtained. The working surface of the light-transmitting sleeve 341 of the light-transmitting cover 340 is free of weld lines, making the working surface of the light-transmitting sleeve 341 smooth and flat. Light can pass through the working surface of the light-transmitting sleeve 341 more smoothly, thereby significantly improving the light transmittance. The light propagation path through the working surface of the light-transmitting sleeve 341 is more stable and regular, which is beneficial to the signal transmission of the rangefinder and ensures the measurement accuracy of the rangefinder. Moreover, since the working surface of the light-transmitting sleeve 341 is free of weld lines, the overall structure of the light-transmitting sleeve 341 is more uniform and consistent, and the intermolecular bonding is tight, which can effectively enhance the impact resistance and fatigue resistance of the light-transmitting sleeve 341 and extend its service life.

[0206] Referring to Figure 27, in some embodiments, in order to form the light-transmitting cover 340, the cavity 330 includes a cover forming part 331, a light-transmitting sleeve forming part 332, and a base forming part 333 connected in sequence.

[0207] When molten material enters the cavity 330 through the injection port 311, it will flow sequentially through the cover forming part 331, the light-transmitting sleeve forming part 332 and the base forming part 333 under the action of gravity to form the cover 342, the light-transmitting sleeve 341 and the base 343, thus forming a complete light-transmitting cover 340 and realizing the preparation of the light-transmitting cover 340.

[0208] Moreover, the molten material enters the cavity 330 through the injection port 311 to achieve injection molding of the light-transmitting cover 340, so that the cover 342, the light-transmitting sleeve 341 and the base 343 are integrally molded, which can reduce the number of parts, reduce assembly steps, improve production efficiency and reduce production costs.

[0209] Referring to Figures 27 and 28, in some embodiments, to further reduce the possibility of weld lines appearing in the light-transmitting cover 340, the injection port 311 is located at the center of the top of the outer mold 310. This ensures a relatively balanced flow path of the molten material to each part of the cavity 330, with minimal differences in flow resistance. This allows the molten material to fill the cavity 330 at a relatively stable flow rate and pressure, reducing instability at the molten material front caused by uneven flow resistance, such as jetting and eddies, thereby lowering the probability of weld lines. Furthermore, the molten material continuously dissipates heat during flow. With the injection port 311 located at the center of the top of the outer mold 310, the heat dissipation of the molten material is relatively similar across different parts as it flows outwards, resulting in smaller temperature differences. The uniformly heated molten material exhibits more stable performance during filling the cavity 330 and during curing, allowing for better fusion and further reducing the probability of weld lines. This improves the mechanical and optical properties of the light-transmitting cover 340.

[0210] Meanwhile, the injection port 311 is located at the center of the top of the outer mold 310, allowing the molten material to diffuse symmetrically in all directions under the influence of gravity, uniformly filling the cavity 330. This symmetrical flow pattern enables the molten material to reach all corners of the cavity 330 more evenly, avoiding localized insufficient or uneven filling. Uniform filling ensures that every small structure is fully filled, further reducing the probability of weld lines and improving the integrity and consistency of the light-transmitting sleeve 341.

[0211] In some embodiments, the cavity 330 is used to receive molten material injected through the injection port 311, and the light-transmitting cover 340 is integrally formed from the molten material. This can reduce the number of parts, reduce assembly steps, improve production efficiency, and reduce production costs.
