[0049] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0050] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0051] With the rapid development of artificial intelligence technology, various vehicles such as cars and aircraft are becoming increasingly intelligent, and people are placing higher demands on their functions, such as autonomous driving. To achieve autonomous driving, various sensors are indispensable. When sensors are mounted on the vehicle's exterior, the sensors or their critical components, such as lenses, are frequently exposed to the external environment. In muddy roads, sandstorms, or rainy conditions, dust, water, or other debris can easily damage the sensors or their critical components, thus affecting their functionality.

[0052] To address the aforementioned technical problems, embodiments of this application provide a sensor assembly and a carrier. The sensor assembly and carrier provided in the embodiments of this application will now be described in conjunction with the accompanying drawings.

[0053] Please refer to Figure 1 and Figure 2 The first aspect of this application provides a sensor assembly 10, which includes a housing 1, a fixing component 2, a sensor assembly 3, and a first driving component 4. The housing 1 includes a receiving cavity 11 and a first opening 12 communicating with the receiving cavity 11. The first opening 12 faces a first direction X. The fixing component 2 is disposed in the receiving cavity 11 and includes a second opening 221 that extends through along a second direction Y. The first direction X and the second direction Y intersect. The sensor assembly 3 is housed in the receiving cavity 11 and includes a sliding part 33, a moving plate 34, and a sensor body 31 connected together. The sliding part 33 is movably connected to one side of the fixing component 2. The moving plate 34 is connected to the side of the sliding part 33 away from the fixing component 2. The sensor body 31 is connected to the side of the moving plate 34 away from the sliding part 33. The first driving component 4 includes a driving member and a driving connector (not shown in the figure) connected together. The driving member is disposed on the side of the fixing component 2 away from the sensor assembly 3. The driving connector is connected to the sliding part 33 via the second opening 221.

[0054] The driving component drives the driving connector to move along the first direction X, thereby driving the sliding part 33 to move. The sliding part 33 drives the moving plate 34 and the sensor body 31 to move along the first direction X between the first position and the second position relative to the fixed component 2. When the sensor component 3 is in the first position, the sensor component 3 is housed in the receiving cavity 11. When the sensor component 3 is in the second position, the sensor component 3 extends at least partially out of the first opening 12.

[0055] The sensor body 31 can be a laser sensor, an infrared ray sensor, or a radar sensor, etc. The drive assembly 4 can include a linear motor. The drive assembly 4 can be fastened to the fixing assembly 2 or to the housing 1.

[0056] The size of the second opening 221 is set according to the size of the drive connector. It should be understood that the smaller the size of the second opening 221, the less likely external liquids and impurities are to enter the drive assembly 4 through the second opening 221 and thus affect the operation of the drive assembly 4; the better its waterproof and dustproof performance. Therefore, the size of the second opening 221 can be set as small as possible, ensuring that the drive connector can pass through the second opening 221 and drive the sensor assembly 3 to move normally. Optionally, the drive component is a linear drive motor.

[0057] A motion plate 34 is provided to support the sensor body 31, and a sliding part 33 slides on the fixed component 2, driving the motion plate 34 and the sensor body 31 to move. The sliding part 33 helps to reduce the resistance to the movement of the sensor assembly 3, making its sliding smoother, and the motion plate 34 supporting the sensor body 31 can improve the structural strength of the sensor assembly 3. Optionally, the sliding part 33 is a slider.

[0058] Sensor assembly 3 has an operating state and an inactive state. When sensor assembly 10 is in the inactive state, drive assembly 4 can drive sensor assembly 3 to be positioned relative to fixed assembly 2 in a first position, such as... Figure 3 As shown. When the sensor assembly 10 is in the working state, the drive component 4 can drive the sensor assembly 3 to be positioned relative to the fixed component 2 in a second position, with the sensor assembly 3 at least partially extending out of the first opening 12, as shown. Figure 4 As shown. For example, the sensor body 31 is a laser sensor, which includes a laser emitter, a laser receiver, and other structures. When the sensor assembly 10 is in operation, only the laser emitter can extend out of the first opening 12. Of course, when the sensor assembly 10 is in operation, the entire sensor assembly 3 can extend out of the first opening 12.

[0059] The sensor assembly 10 provided in this application embodiment has a first driving component 4 that can drive the sensor assembly 3 to move between a first position and a second position relative to the fixed component 2. When the sensor assembly 3 is in the first position relative to the fixed component 2, both the driving component 4 and the sensor assembly 3 are housed in the receiving cavity 11 of the housing 1, which can reduce or prevent liquids and impurities from entering the receiving cavity 11 to a certain extent, thereby reducing or preventing liquids and impurities from affecting the operation of the driving component 4 and the sensor assembly 3. When the sensor assembly 3 is in the second position relative to the fixed component 2, the sensor assembly 3 extends at least partially out of the first opening 12 to obtain a larger detection range. The driving component 4 is disposed in the receiving cavity 11, and the sensor assembly 3 can extend or retract into the receiving cavity 11 under the drive of the driving component 4, reducing the time that the sensor assembly 3 is exposed to the external environment and preventing liquids or impurities in the external environment from affecting or even damaging the sensor assembly 3 and the driving component 4.

[0060] Please continue to refer to Figure 2 In some optional embodiments, the sliding part 33 is provided with a groove 331 recessed along the second direction Y, and the driving connector is placed in the groove 331. The shape of the groove 331 is adapted to the shape of the driving connector, and the groove 331 can limit the movement of the driving connector. By providing the groove 331, the driving connector extends into the groove 331, making it easier for the driving connector to connect with the sliding part 33 and making it easier to drive the sliding part 33 to move.

[0061] Please refer to the reference. Figures 1 to 6 In some alternative embodiments, the fixing component 2 includes a fixing plate 22 and a slide groove 21, the second opening 221 penetrates the fixing plate 22, the slide groove 21 is disposed on the fixing plate 22, the slide groove 21 extends along the first direction X, and the sliding part 33 is partially placed in the slide groove 21.

[0062] By providing a groove 21 on the fixed plate 22, the sliding path of the sliding part 33 is constrained by the groove 21, making the movement trajectory of the sliding part 33 more accurate, thereby allowing the sensor assembly 3 to extend precisely from the first opening 12. In addition, the groove 21 can reduce the sliding resistance of the sliding part 33. The extension direction of the groove 21 can be consistent with the opening direction of the first opening 12.

[0063] Optionally, there are two slides 21, which are respectively located on both sides of the second opening 221. The two slides 21 extend along the first direction X, and the constraint effect of the two slides 21 on the sensor assembly 3 is better, which can reduce or avoid the shaking of the sensor assembly 3 relative to the fixed assembly 2.

[0064] In some alternative embodiments, the fixing component 2 further includes a baffle 23 that extends along a first direction X and is connected to the fixing plate 22, the baffle 23 being disposed at least around a portion of the second opening 221.

[0065] The baffle 23 is used to shield the drive connector of the drive assembly 4, reducing or preventing the impact of liquids and impurities on the drive connector. In addition, the baffle 23 also improves the aesthetics by shielding the drive connector. Optionally, there are two baffles 23, which are spaced apart along the third direction Z and are located on both sides of the second opening 221 to better shield the drive connector.

[0066] In some alternative embodiments, the fixing component 2 further includes a limiting member 24, which is located at the end of the slide groove 21 away from the first opening 12.

[0067] The limiting member 24 is used to limit the sliding stroke of the sliding part 33 within the slide groove 21, preventing the sliding part 33 from sliding further into the outer casing 1 after reaching the first position. The limiting member 24 can also be connected to the baffle 23 to fix the baffle 23 and improve its strength.

[0068] It should be understood that the sliding stroke of the sliding part 33 in the slide groove 21 can also be limited by other means. For example, a limiting mechanism for the drive connector can be provided on the drive assembly 4, or a slide groove 21 of appropriate length can be provided to limit the sliding stroke of the sliding part 33 at the end of the slide groove 21 along the first direction X.

[0069] Please refer to Figure 7 In some alternative embodiments, the edge of the fixing plate 22 contacts the housing 1, the fixing plate 22 divides the receiving cavity 11 into a first chamber 111 and a second chamber 112, the first opening 12 communicates with the first chamber 111, the sensor assembly 3 is housed in the first chamber 111, and the drive element of the drive assembly 4 is housed in the second chamber 112.

[0070] In these alternative embodiments, when the sensor assembly 3 is located in the first position relative to the fixed assembly 2, the drive component of the sensor assembly 3 is housed in the first chamber 111, and the drive component of the drive assembly 4 is housed in the second chamber 112. This can reduce or prevent the influence of liquid and impurities on the operation of the drive assembly 4 and the sensor assembly 3 to a certain extent. When the sensor assembly 3 is located in the second position relative to the fixed assembly 2, the sensor assembly 3 extends out from the first opening 12 under the drive of the drive assembly 4, and the drive component of the drive assembly 4 is still located in the second chamber 112. This is to prevent liquid and impurities that have entered the first chamber 111 through the first opening 12 from further entering the second chamber 112 and affecting the operation of the drive assembly 4.

[0071] Please refer to the reference. Figures 8 to 10 In some alternative embodiments, the sensor assembly 3 further includes a housing 32 that covers the sensor body 31. The housing 32 includes a first sealing strip 321, which is pressed against the housing 1 when the sensor assembly 3 is in the second position.

[0072] The housing 32 covers the outside of the sensor body 31, serving two purposes: firstly, to protect the sensor body 31, especially when the sensor assembly 3 is in the second position, extending out of the first opening 12 and directly exposed to the external environment; secondly, the housing 32 provides excellent protection for the sensor body 31. Optionally, the housing 32 also serves a decorative function, enhancing its appearance. Optionally, the housing 32 is provided with a first sealing strip 321. When the sensor assembly 31 is in the second position, extending out of the first opening 12, the first sealing strip 321 is pressed against the housing 1, reducing or preventing liquids and impurities from entering through the gap between the sensor assembly 3 and the housing 1, thus affecting the operation of the sensor body 31 and further improving the waterproof and dustproof performance of the sensor assembly 10.

[0073] Please refer to Figure 11 and Figure 12 In some alternative embodiments, the housing 1 further includes a cover plate 17, which is movably disposed over the first opening 12. When the sensor assembly 3 is in the first position, the cover plate 17 is disposed over the first opening 12. When the sensor assembly 3 is in the second position, the cover plate 17 is spaced apart from the first opening 12.

[0074] When the sensor assembly 10 is not in operation, the cover plate 17 covers the first opening 12, sealing the receiving cavity 11 and improving the waterproof and dustproof performance of the sensor assembly 10. When the sensor assembly 10 is in operation, the cover plate 17 is opened so that the sensor assembly 3 can extend from the first opening 12.

[0075] In some alternative embodiments, the sensor assembly 10 further includes a second drive assembly (not shown in the figure), which is disposed in the receiving cavity 11 and connected to the cover plate 17, and is used to drive the cover plate 17 to move.

[0076] When the sensor assembly 3 moves from the first position to the second position, the second drive assembly drives the cover plate 17 to move away from the first opening 12 along the surface of the outer shell 1 where the first opening 12 is opened. When the sensor assembly 3 moves from the second position to the first position, the second drive assembly drives the cover plate 17 to move closer to the first opening 12 along the surface of the outer shell 1 where the first opening 12 is opened.

[0077] The second drive assembly is configured to drive the opening and closing of the cover plate 17, thereby improving the level of automation. Optionally, an interlocking device is provided between the second drive assembly and the first drive assembly 4. The first drive assembly 4 can only drive the sensor assembly 3 to move normally when the cover plate 17 is opened by the second drive assembly, preventing the sensor assembly 3 from colliding with the cover plate 17 and causing damage when the cover plate 17 is closed.

[0078] In some alternative embodiments, the cover plate 17 includes a first cover body, a second cover body, and a second sealing strip (not shown in the figure). The first cover body and the second cover body are stacked, and the second sealing strip is disposed around the edge of the second cover body. When the cover plate 17 covers the first opening 12, the second sealing strip seals the outer shell 1 and the cover plate 17.

[0079] The first cover is an exterior component, serving both aesthetic and concealment functions of the internal structure. When the sensor assembly 10 is not in operation, the second sealing strip seals the second cover and the outer shell 1, further improving the waterproof and dustproof performance of the sensor assembly 10.

[0080] Please refer to the reference. Figures 13 to 17 In some alternative embodiments, the sensor assembly 10 further includes a wiring harness 5, the mounting plate 22 includes a third opening 222 communicating with the first chamber 111 and the second chamber 112, the housing 1 has a fourth opening 15 communicating with the second chamber 112, and the wiring harness 5 passes through the fourth opening 15, the second chamber 112 and the third opening 222 in sequence to connect with the sensor assembly 3.

[0081] Most of the wiring harness 5 of the sensor assembly 10 is housed within the second chamber 112. One end of the wiring harness 5 passes through the third opening 222 and connects to the sensor assembly 3, while the other end passes through the fourth opening 15 and extends outside the housing 1. This reduces or prevents the wiring harness 5 from being directly exposed to the external environment, which could cause aging or other damage. The third opening 222 and the fourth opening 15 are used to house the wiring harness 5, reducing the connection between the second chamber 112 and the outside environment, and reducing or preventing external liquids or impurities from entering the second chamber 112, thus improving the waterproof and dustproof performance of the sensor assembly 10.

[0082] In some alternative embodiments, the sensor assembly 10 further includes a seal 7 having a through hole 71 through which the wiring harness 5 passes, the seal 7 sealing the fourth opening 15, and the housing 1 further includes a water-blocking rib 18 disposed at least around a portion of the fourth opening 15.

[0083] The seal 7 prevents liquids and impurities from entering the housing 1 through the fourth opening 15, improving the waterproof and dustproof performance of the sensor assembly 10. The water-retaining rib 18 prevents liquids from entering the housing 1 through the fourth opening 15, and also acts as a guide, directing water flow along the rib 18 to bypass the fourth opening 15. Optionally, the fourth opening 15 can be rectangular, with the water-retaining rib 18 positioned around one long axis and one short axis of the fourth opening 15.

[0084] In some alternative embodiments, the seal 7 includes a cover 72 and a snap fastener 73, with a through hole 71 disposed in the cover 72, the cover 72 covering the fourth opening 15, and the snap fastener 73 engaging with the outer shell 1.

[0085] The cover 72 and the fastener 73 can be integrally molded. The fastener 73 surrounds the cover 72 and has a slot 731. The outer shell 1 is placed in the slot 731 and engages with the fastener 73. Optionally, after the fastener 73 and the outer shell 1 are engaged, waterproof adhesive can be applied between the fastener 73 and the outer shell 1 to further secure them and improve their waterproof performance.

[0086] Please refer to the reference. Figures 13 to 17 In some optional embodiments, the sensor assembly 10 further includes a wire harness clip 6 for securing the wire harness 5. The wire harness clip 6 is disposed on the drive component. The wire harness clip 6 partially secures the wire harness 5 to one side of the drive component. During the movement of the sensor assembly 3, the wire harness clip 6 provides a certain limiting effect on the wire harness 5, preventing the wire harness 5 from becoming tangled due to the back-and-forth movement of the sensor assembly 3. Optionally, the selection point of the wire harness clip 6 is located near the midpoint of the wire harness 5's travel distance, which minimizes the change in wire length when the wire harness 5 is bent, effectively extending the bending life of the wire harness 5.

[0087] In some alternative embodiments, the fixing component 2 also has a drainage groove 25 that connects to the slide 21 and the second chamber 112, and the housing 1 has a drainage hole 16 that connects to the second chamber 112.

[0088] During and after the sensor assembly 3 extends out of the first opening 12, some liquid and impurities will enter the first chamber 111. The sliding part 33 of the sensor assembly 3 can play a cleaning role during the sliding process, sweeping water and dust to both ends of the slide groove 21, and then draining the liquid and impurities into the second chamber 112 through the drainage groove 25 connected to both ends of the slide groove 21. The outer shell 1 is provided with a drainage hole 16 connecting the second chamber 112 and the outside. The drainage hole 16 drains the liquid and impurities in the second chamber 112, avoiding damage to the sensor assembly 3 and the drive assembly 4 caused by the long-term accumulation of liquid and impurities. Optionally, the drainage hole 16 is located at the lowest point of the outer shell 1 relative to the ground, and the liquid and impurities are drained from the drainage hole 16 by their own gravity.

[0089] Please refer to the reference. Figure 18 and Figure 19 In some optional embodiments, the outer casing 1 includes a first casing 13 and a second casing 14, which overlap each other to form a receiving cavity 11. The first casing 13 and the second casing 14 can be connected by screws and / or adhesive to ensure the overall waterproof and dustproof properties of the outer casing 1. Optionally, a first opening 12 is formed in the first casing 13. In these optional embodiments, the outer casing 1 is formed by the overlap of the first casing 13 and the second casing 14, which facilitates the installation of other structures inside the outer casing 1 and is also more conducive to the processing and shaping of the outer casing 1.

[0090] Optionally, the second housing 14 has a mounting groove (not shown in the figure), and the fixing component 2 is partially inserted into the mounting groove and connected to the second housing 14. Optionally, the portion of the fixing component 2 inserted into the mounting groove has an interference fit with the mounting groove, making the connection more secure. For example, the surface of the fixing component 2 that contacts the mounting groove is provided with a protrusion 26, and the protrusion 26 abuts against the surface of the mounting groove to achieve an interference fit between the fixing component 2 and the mounting groove.

[0091] Optionally, the fixing assembly 2 further includes a mounting base 27 connected to the fixing plate 22, and the mounting base 27 is bolted to the second housing 14. The mounting base 27 is located at the edge of the fixing plate 22, and the mounting base 27 can be integrally formed with the fixing plate 22. The mounting base 27 is provided with threaded holes, through which bolts can be connected to the second housing 14. Optionally, there are four mounting bases 27, which are distributed circumferentially around the fixing plate 22. The mounting bases 27 are bolted to the second housing 14 to improve the connection strength between the fixing assembly 2 and the second housing 14.
