When the one-way locking ring rotates in a first direction to perform a one-way locking function, the locking portion locks with the locked component. When the one-way locking ring rotates in a second direction opposite to the first direction, the one-way locking ring disengages from the locked component through radial elastic deformation.

Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to a one-way locking ring, a one-way locking assembly, and a vehicle. Background Technology

[0002] Most car side mirrors now come with power folding functionality. It's necessary to ensure the mirrors can be switched between at least two positions: a driving position (expanded) and a parking position (folded). In the driving position, manual forward and backward folding is required to protect pedestrians from secondary injuries in the event of a collision. In the parking position, manual forward folding is also required. When the manual function is engaged, the clutch inside the folding mechanism disengages, leaving the mirror in a relaxed state. Power inward folding then resets the clutch mechanism to the locked position. In other words, regardless of any malfunction in the folding mechanism, it can be reset via power inward folding to ensure normal use by the driver.

[0003] To ensure stable driving position, folding devices are equipped with a one-way locking mechanism; however, the existing one-way locking mechanism consists of one or more metal cylinders and one or more helical return springs. The parts are expensive to manufacture, the assembly process is complex, and the elastic deformation is axial, which makes the axial space of the one-way locking mechanism occupy a large amount.

[0047] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0050] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0051] One aspect of this application provides a one-way locking component, such as Figure 1 and Figure 2 As shown, the one-way locking assembly 2 is disposed within the housing on which the rearview mirror lens is mounted; the housing also houses a drive mechanism 3 capable of rotating and unfolding and folding the rearview mirror lens relative to the one-way locking assembly 2. One preferred embodiment of the one-way locking assembly 2 includes a support member, a gear sleeve 23, and a one-way locking ring 24. The support member can be fixedly mounted on a mirror temple support at the front of the vehicle; the housing and the support member are rotatably coupled, allowing the drive mechanism 3 to drive the housing to rotate the rearview mirror around the support member. The gear sleeve 23 is rotatably mounted on the support member and engages with it in a circumferential limiting manner. The gear sleeve 23 engages with the drive mechanism 3 within the housing, such that when the gear sleeve 23 is circumferentially limited, the driving force applied to the gear sleeve 23 by the drive mechanism 3 can react on itself, causing the housing and the rearview mirror to rotate around the gear sleeve 23. The one-way locking ring 24 is sleeved on the outside of the gear sleeve 23 and cooperates with the gear sleeve 23. At the same time, the one-way locking ring 24 can also cooperate with the housing for driving.

[0052] When the rearview mirror is manually folded forward, the housing can drive the one-way locking ring 24 to rotate synchronously in the first direction. At this time, the one-way locking ring 24 can lock with the gear sleeve 23, so that the gear sleeve 23 can rotate synchronously in the first direction with the one-way locking ring 24 and the housing. At this time, the gear sleeve 23 can disengage from the limiting engagement with the support member to avoid the rigid limiting of the gear sleeve 23 interfering with the manual folding of the rearview mirror, thereby preventing damage to the rearview mirror. After the rearview mirror is manually folded forward, when the rearview mirror is reset and folded by the drive mechanism 3, the gear sleeve 23 can be circumferentially limited by the support member again. Then, the drive mechanism 3 can drive the housing to rotate relative to the gear sleeve 23 in the second direction opposite to the first direction. During this process, the housing can again drive the one-way locking ring 24 to rotate synchronously in the second direction. At this time, the one-way locking ring 24 can disengage from the gear sleeve 23 through radial elastic deformation, achieving synchronous rotation relative to the gear sleeve 23.

[0053] Understandably, in the technical solution of this application, the function of the one-way locking ring 24 is to lock and engage the gear sleeve 23 when the rearview mirror is manually folded forward, thereby driving the gear sleeve 23 out of its limit position and ensuring the safety of manual folding. When the rearview mirror is electrically and automatically reset via the drive mechanism 3, to prevent the gear sleeve 23 from disengaging from its limit position again due to contact with the gear sleeve 23, the one-way locking ring 24 can disengage from the gear sleeve 23 through radial elastic deformation. It should be noted that the radial elastic deformation of the one-way locking ring 24 is always within its elastic limit, and the one-way locking ring 24 can return to its natural state after disengaging from the gear sleeve 23 through elastic deformation.

[0054] In the technical solution of this application, the one-way locking ring 24 can achieve locking with the locked part in the first direction and relative free rotation in the second direction simply by its own deformation. Compared with the traditional multi-part one-way locking mechanism, it can effectively reduce costs, while also reducing installation space and simplifying the assembly process.

[0055] In this embodiment, as Figures 1 to 3 As shown, to facilitate the installation of the one-way locking component 2, the housing can be divided into upper and lower parts, namely, the housing includes an upper housing 11 and a lower housing 12; after the upper housing 11 and the lower housing 12 are detachably fixedly connected, an installation space can be formed inside. The drive mechanism 3 and the one-way locking component 2 are located on both sides of the installation space inside the housing, respectively. The specific structure of the drive mechanism 3 is well known to those skilled in the art, and will be briefly described below for ease of understanding.

[0056] Specifically, such as Figure 2As shown, the drive mechanism 3 includes a controller, an actuator, and a transmission assembly. The actuator is fixedly mounted on the housing and is typically a servo motor, such as a permanent magnet bidirectional DC motor. The controller is fixedly mounted on the actuator or the housing and is connected to the actuator via a signal connection. The controller can control the actuator's movement based on the received signal. The gear sleeve 23 can mesh with the output end of the transmission assembly via teeth on its outer side. Alternatively, a drive gear 31 can be mounted on the outer side of the gear sleeve 23 to mesh with the output end of the transmission assembly. In this embodiment, it is preferable to mount a separate drive gear 31 on the outer side of the gear sleeve 23, thereby reducing the machining difficulty of the gear sleeve 23. The connection between the drive gear 31 and the gear sleeve 23 can be a key connection or a spline-like connection; the specific configuration can be determined according to the actual needs of those skilled in the art. The transmission assembly transmits the power of the actuator to the drive gear 31, allowing the drive gear 31, under the action of being limited, to reverse the direction and drive the drive mechanism 3 to rotate the housing and the rearview mirror around the support member. There are various structural forms of transmission components. To ensure safe and stable transmission, a specific example of a transmission component will be given below.

[0057] Specifically, the drive gear 31 can be a helical gear, and the transmission assembly includes a worm gear and a worm shaft mounted coaxially. The worm gear and worm shaft are mounted horizontally in the axial direction, while the actuator is mounted vertically. The actuator meshes with the worm gear through the worm section at its output end, and the worm shaft, coaxially mounted with the worm gear, meshes with the drive gear 31. This two-stage reduction effectively reduces the output rotation of the actuator, ensuring the rearview mirror rotates at an appropriate speed. The helical gear design of the drive gear 31 ensures transmission accuracy, and the worm gear transmission enables mechanical self-locking.

[0058] In this embodiment, there are multiple specific structural forms for the support member to circumferentially limit the gear sleeve 23. For ease of understanding, two specific examples will be described in detail below.

[0059] Example 1: such as Figure 2 As shown, the support includes a bearing seat 21 and a limiting component 22. The bearing seat 21 can be fixedly installed, meaning that the bearing seat 21, the mirror foot support, the gear sleeve 23, and the housing are all rotatably engaged with the bearing seat 21. The limiting component 22 is installed on the bearing seat 21 and can elastically engage with the gear sleeve 23 axially or radially, thereby limiting the circumferential rotation of the gear sleeve 23. When the driving force of the gear sleeve 23 in the circumferential direction exceeds a set threshold, the limiting component 22 can move away from the gear sleeve 23 axially or radially to release the circumferential rotation restriction on the gear sleeve 23.

[0060] Specifically, such as Figure 4As shown, the bearing seat 21 includes a base 211 and a support shaft 212. The support shaft 212 is located in the middle of the base 211. The base 211 and the support shaft 212 can be connected separately or integrally formed, depending on the actual needs of those skilled in the art. The bearing seat 21 can be fixedly set by the base 211, and the gear sleeve 23 and the housing are rotatably mounted on the support shaft 212. The diameter of the support shaft 212 is smaller than the diameter of the base 211, so that the base 211 supports the housing. The limiting component 22 includes an elastic element and a limiting element. The limiting element is slidably mounted on the support shaft 212 along the axial or radial direction through the elastic element and engages with the limiting groove 230 provided on the gear sleeve 23. When the driving force of the gear sleeve 23 in the circumferential direction is greater than the limiting force between the limiting element and the limiting groove 230, the limiting element can move away from the gear sleeve 23 in the axial or radial direction.

[0061] It is understandable that the specific structure of the limiting component is different because the engagement direction between the limiting component and the gear sleeve 23 is different. For ease of understanding, the following will describe in detail the limiting component through a specific structure for the axial and radial engagement between the limiting component and the gear sleeve 23.

[0062] For the axial engagement between the limiting component and the gear sleeve 23.

[0063] like Figure 4 and Figure 5 As shown, the support shaft 212 includes a smooth shaft section 2121 and a limiting section 2122. The smooth shaft section 2121 is located at the lower part of the support shaft 212, and the gear sleeve 23 is rotatably mounted on the smooth shaft section 2121 to ensure smooth rotation of the gear sleeve 23. The limiting component is a limiting sleeve 221. The specific type of elastic component can be various, such as a spring 222 or a spring sheet; in this embodiment, a spring 222 is preferred. The limiting sleeve 221 and the limiting section 2122 can be axially slidably connected in a manner similar to a spline connection. The spring 222 is sleeved on the limiting section 2122, and both ends of the spring 222 cooperate with the limiting sleeve 221 and the support shaft 212 respectively, so that the limiting sleeve 221 can elastically abut against the upper end of the gear sleeve 23 under the elastic force of the spring 222 and perform axial limiting engagement.

[0064] For the limiting engagement between the gear sleeve 23 and the limiting sleeve 221, the upper end of the gear sleeve 23 can be provided with a limiting groove 230, and the lower end of the limiting sleeve 221 can be provided with a limiting block 2211; alternatively, the upper end of the gear sleeve 23 can be provided with a limiting block 2211, and the lower end of the limiting sleeve 221 can be provided with a limiting groove 230. For ease of understanding, the following example will be taken with the limiting groove 230 on the gear sleeve 23 and the limiting block 2211 on the limiting sleeve 221. The limiting groove 230 and the limiting block 2211 engage axially to ensure that the gear sleeve 23 remains stationary relative to the bearing 21 within a certain driving force range. The limiting groove 230 and the limiting block 2211 have wedge-shaped or arc-shaped surfaces on both sides along the circumferential direction. When the external force on the gear sleeve 23 is greater than the set threshold, the gear sleeve 23 can lift the limiting sleeve 221 along the axial direction, so that the limiting groove 230 and the limiting block 2211 are disengaged, thereby releasing the limitation of the limiting sleeve 221 on the circumferential rotation of the gear sleeve 23.

[0065] Understandably, to ensure stable limit switching, the number of limit slots 230 and corresponding limit blocks 2211 can be set to one or more, for example... Figure 5 As shown, there are three limiting grooves 230 and three limiting blocks 2211, which are arranged at equal intervals along the circumference. There are two main installation methods for the spring 222: the first is that the spring 222 drives the limiting sleeve 221 to engage with the gear sleeve 23 through tension; the second is that the spring 222 drives the limiting sleeve 221 to engage with the gear sleeve 23 through compression. For the first installation method, the upper end of the spring 222 needs to be connected to the limiting sleeve 221, and the lower end of the spring 222 needs to be connected to the support shaft 212. For the second installation method, the upper end of the spring 222 needs to abut or connect with the top of the support shaft 212, and the lower end of the spring 222 needs to abut or connect with the limiting sleeve 221.

[0066] It should be understood that both installation methods of the spring 222 described above can meet the requirements of this application. For the first installation method of the spring 222, to avoid interference between the spring 222 and the gear sleeve 23, the spring 222 needs to be located between the gear sleeve 23 and the limiting sleeve 221. Therefore, to ensure that the limiting sleeve 221 can cooperate with the gear sleeve 23 and the drive gear 31, the axial dimension of the limiting sleeve 221 needs to be designed to be relatively long; and both ends of the spring 222 need to be fixedly connected. Therefore, in this embodiment, the second installation method described above is preferred for the spring 222. In the second installation method of the spring 222, to ensure the installation of the limiting sleeve 221, the limiting section 2122 is set with a constant diameter. Therefore, a retaining sleeve 223 for limiting the upper end of the spring 222 needs to be installed on the top of the limiting section 2122. For the installation of the limiting component 22, the limiting sleeve 221 can be installed on the limiting section 2122 first, then the spring 222 can be installed on the limiting section 2122, and finally the retaining sleeve 223 can be sleeved on the limiting section 2122 in a similar spline connection manner and engaged and fixed with the slot 2123 provided on the limiting section 2122.

[0067] For the radial engagement between the limiting component and the gear sleeve 23.

[0068] The limiting component can be a ball bearing 224, and the elastic component can be a spring 222. The support shaft 212 is provided with a radially extending mounting groove 2124. The ball bearing 224 can be installed in the mounting groove 2124 through the spring 222. The inner side of the gear sleeve 23 is provided with a limiting groove 230. When the gear sleeve 23 is rotatably mounted on the support shaft 212, it can be radially engaged with the ball bearing 224 through the limiting groove 230, thereby limiting the circumferential rotation of the gear sleeve 23. When the external force on the gear sleeve 23 is greater than a set threshold, the gear sleeve 23 can radially squeeze the ball bearing 224 into the mounting groove 2124, so that the limiting groove 230 and the ball bearing 224 disengage, thereby releasing the limitation of the ball bearing 224 on the circumferential rotation of the gear sleeve 23.

[0069] It is understandable that, in order to ensure the stability of the limit, the number of balls 224 and limit grooves 230 can be set to multiple, and the multiple limit grooves 230 and balls 224 can be arranged at equal intervals along the circumferential direction.

[0070] Example 2: The support component is a bearing seat 21, which includes a base 211 and a support shaft 212. The specific connection between the base 211 and the support shaft 212 is the same as in Example 1, and therefore will not be repeated here. An integrally connected clutch portion is provided on the support shaft 212. The gear sleeve 23 is rotatably mounted on the support shaft 212 and engages axially or radially with the clutch portion, thereby limiting the circumferential rotation of the gear sleeve 23. When the driving force of the gear sleeve 23 in the circumferential direction exceeds a set threshold, the clutch portion can elastically deform axially or radially away from the gear sleeve 23 to release the circumferential rotation restriction on the gear sleeve 23.

[0071] It is understandable that the specific structure of the clutch is different depending on the engagement direction between the clutch and the gear sleeve 23. For ease of understanding, the specific structure of the clutch will be described in detail below, taking the radial engagement between the clutch and the gear sleeve 23 as an example.

[0072] Specifically, such as Figure 7 As shown, a limiting groove 230 is provided on the inner side of the gear sleeve 23. The clutch part includes a deformation section 2125 and a clutch block 2126. One end of the deformation section 2125 is connected to the support shaft 212, and the clutch block 2126 is disposed on the outer side of the other end of the deformation section 2125. The deformation section 2125 is flush with the surface of the support shaft 212, and the clutch block 2126 protrudes from the surface of the support shaft 212. Figure 7 As shown in (1), when the gear sleeve 23 is installed on the support shaft 212, the gear sleeve 23 can be radially engaged with the clutch block 2126 through the limiting groove 230, thereby achieving circumferential rotation limitation of the gear sleeve 23. Figure 7 As shown in (2), when the driving force of the gear sleeve 23 in the circumferential direction is greater than the set threshold, the clutch block 2126, squeezed by the gear sleeve 23, can drive the deformation section 2125 to bend and deform inward toward the support shaft 212, so that the clutch block 2126 disengages from the limiting groove 230, thereby releasing the restriction on the circumferential rotation of the gear sleeve 23. For the disengagement of the clutch block 2126 from the limiting groove 230, the two sides of the clutch block 2126 and the limiting groove 230 in the circumferential direction can be set as wedge-shaped surfaces or arc-shaped surfaces.

[0073] In this embodiment, to ensure accurate positioning of the housing when it rotates to a set position, a positioning structure can be provided between the lower end face of the lower housing 12 and the upper end face of the base 211. Specifically, as shown... Figure 3 and Figure 4As shown, the positioning structure includes a positioning block 123 and a positioning groove 2110. Alternatively, the positioning block 123 can be located on the lower end face of the lower housing 12, and the positioning groove 2110 on the upper end face of the base 211; or the positioning block 123 can be located on the upper end face of the base 211, and the positioning groove 2110 on the lower end face of the lower housing 12. The specific configuration of the positioning structure can be customized according to the actual needs of those skilled in the art. To ensure that the lower housing 12 can rotate relative to the base 211, the positioning block 123 and the positioning groove 2110 need to be wedge-shaped in the circumferential direction, so that the lower housing 12 can, under a certain driving force, disengage the positioning block 123 from the positioning groove 2110 to rotate relative to it.

[0074] It should be noted that the two commonly used positions of the rearview mirror include the unfolded position and the folded position. Therefore, at least one positioning groove 2110 should be provided to ensure that the rearview mirror is stably positioned in the unfolded position. Of course, to further enhance the positioning stability of the rearview mirror in the unfolded position and to ensure the positioning stability of the rearview mirror in the folded position, multiple positioning blocks 123 and positioning grooves 2110 can be provided, with multiple positioning blocks 123 and positioning grooves 2110 arranged at equal intervals along the circumferential direction.

[0075] Another aspect of this application provides a one-way locking ring, one preferred embodiment of which is as follows: Figures 8 to 10 As shown, the one-way locking ring 24 is provided with a locking part 241. When the one-way locking ring 24 rotates in the first direction, the locking part 241 engages with the locked member, so that the one-way locking ring 24 performs the one-way locking function of driving the locked member to rotate synchronously. When the one-way locking ring 24 rotates in the second direction opposite to the first direction, the one-way locking ring 24 disengages the locking part 241 from the locked member through radial elastic deformation.

[0076] It is understandable that when the aforementioned one-way locking ring 24 is applied to the aforementioned one-way locking assembly 2, the locked component is the gear sleeve 23. Regarding the elastic deformation direction of the one-way locking ring 24, for example... Figure 10 As shown, the elastic deformation can be radially outward, and correspondingly, it can also be radially inward. For the one-way locking ring 24 to undergo outward elastic deformation, as shown... Figure 11As shown, the one-way locking ring 24 can be fitted onto the outer side of the gear sleeve 23. In this case, the one-way locking ring 24 can engage with the gear sleeve 23 through the locking portion 241 provided on the inner side or end. Alternatively, the one-way locking ring 24 can be fitted onto the inner side of the gear sleeve 23, where it can also engage with the gear sleeve 23 through the locking portion 241 provided on the outer side or end. Considering that the one-way locking ring 24 needs to engage with the housing and that its radial deformation requires sufficient space, in this embodiment, the locking portion 241 is preferably located on the inner side of the one-way locking ring 24. Therefore, when the one-way locking ring 24 rotates in the second direction, it can cause the locking portion 241 to undergo radial outward elastic deformation, thereby ensuring that the locking portion 241 can disengage from the gear sleeve 23.

[0077] In this embodiment, there are multiple locking methods between the locking part 241 and the gear sleeve 23. For example, a retaining groove can be provided recessed on the outer side of the gear sleeve 23, and the locking part 241 extends into the retaining groove to lock with the gear sleeve 23; or, for example... Figure 5 As shown, a stop 231 can be provided outward on the outer side of the gear sleeve 23, and a locking engagement is achieved by the locking part 241 abutting against the stop 231. Both of the above methods can meet the actual needs of this application. Considering that the machining difficulty of the stop 231 is lower than that of the stop groove, in this embodiment, it is preferable to provide a stop 231 and a locking part 241 on the outer side of the gear sleeve 23 for locking.

[0078] In this embodiment, there are various specific structures for the locking part 241 and the stop 231 to cooperate in order to lock the locking part 241 and drive the one-way locking ring 24 to deform radially. For ease of understanding, one of these structures will be described in detail below. Specifically, such as... Figures 5 to 10 As shown, the baffle 231 has a first abutting surface 2311 and a first pressing surface 2312 on both sides along the circumferential direction; the locking part 241 has a second abutting surface 2411 and a second pressing surface 2412 on both sides along the circumferential direction; the first abutting surface 2311 and the second abutting surface 2411 are both parallel to the radial direction of the one-way locking ring 24.

[0079] When the rearview mirror is manually folded forward to drive the housing to rotate in the first direction, such as Figure 9 , Figure 12 as well as Figure 13 As shown, the locking part 241 abuts against the first abutting surface 2311 of the stop 231 via the second abutting surface 2411 to lock the gear sleeve 23. That is, at this time, the rotation paths 400 of the gear sleeve 23 and the one-way locking ring 24 coincide. When the drive mechanism 3 drives the manually folding rearview mirror to reset and fold, as... Figure 10As shown, the baffle 231 performs wedge-shaped or arc-shaped compression through the first compression surface 2312 and the second compression surface 2412 to drive the one-way locking ring 24 to undergo radial elastic deformation. At this time, the rotation path 400 of the gear sleeve 23 relative to the one-way locking ring 24 does not contact the locking part 241 of the one-way locking ring 24, that is, the locking part 241 is located outside the rotation path 400 of the gear sleeve 23.

[0080] In this embodiment, as Figure 8 As shown, at least one locking part 241 is provided; to improve locking stability, multiple locking parts 241 can preferably be provided, with the multiple locking parts 241 being equally spaced along the circumferential direction of the one-way locking ring 24. Accordingly, as... Figure 5 As shown, a corresponding number of stops 231 are also provided, and the stops 231 are equally spaced along the circumference of the gear sleeve 23. The specific number of locking parts 241 and stops 231 can be selected according to the actual needs of those skilled in the art, for example, 5 and Figure 8 As shown, the number of locking parts 241 and stop 231 is set to three.

[0081] In this embodiment, as Figures 8 to 10 As shown, the one-way locking ring 24 includes a first connecting section 244 and a second connecting section 245. The second connecting section 245 is disposed on both sides of the locking portion 241; the radial thickness of the first connecting section 244 is greater than the thickness of the second connecting section 245, and the axial height of the first connecting section 244 is less than the height of the second connecting section 245. Therefore, when the one-way locking ring 24 undergoes radial deformation, because the thickness of the second connecting section 245 is thinner than that of the first connecting section 244, the one-way locking ring 24 is more prone to radial elastic deformation at the position of the locking portion 241. To ensure the service life of the second connecting section 245, the axial height of the second connecting section 245 can be set higher, which can effectively improve the connection strength of the second connecting section 245.

[0082] It is understandable that the specific number of the first connecting segment 244 and the second connecting segment 245 is equal to the number of locking parts 241, that is, each locking part 241 is provided with a second connecting segment 245 on both sides, and a first connecting segment 244 is provided between two adjacent locking parts 241. The first connecting segment 244 can not only improve the bending strength of the one-way locking ring 24 away from the locking part 241, but also play a supporting role when installing the one-way locking ring 24.

[0083] Specifically, such as Figure 3 , Figure 8 and Figure 17As shown, the lower housing 12 is rotatably mounted on the support shaft 212 of the bearing seat 21 through the mounting hole 120. A support seat 122 is provided on the side of the lower housing 12 at the mounting hole 120. The one-way locking ring 24 is sleeved on the gear sleeve 23 and supported on the support seat 122 through the first connecting section 244. The support seat 122 can be annularly arranged on the lower housing 12 or a segmented structure. Considering that the support seat 122 should not interfere with the radial deformation of the one-way locking ring 24, a segmented structure is preferred in this embodiment. Therefore, the specific number of support seats 122 corresponds to the number of first connecting sections 244, and the side of the mounting hole 120 of the lower housing 12 can form a clearance area 124 between two adjacent support seats 122 that does not interfere with the radial deformation of the one-way locking ring 24.

[0084] In this embodiment, as Figure 3 and Figure 8 As shown, a stop block 242 and a push block 243 are arranged at circumferential intervals on the outer side of the one-way locking ring 24. A stop seat 121 is provided on the side of the mounting hole 120 of the lower housing 12 at the corresponding position of the one-way locking ring 24. When the rearview mirror is manually folded forward, as... Figure 12 and Figure 13 As shown, the lower housing 12 can abut against the stop block 242 of the one-way locking ring 24 via the stop seat 121, thereby driving the one-way locking ring 24 to rotate synchronously with the housing in the first direction. When the rearview mirror is manually folded forward and then reset, as shown... Figure 18 and Figure 20 As shown, the lower housing 12 can abut against the push block 243 of the one-way locking ring 24 through the stop seat 121, so as to drive the one-way locking ring 24 to rotate synchronously with the housing in the second direction.

[0085] It is understandable that the number of push blocks 243 and stop blocks 242 can each be set to one. However, to improve the driving stability of the one-way locking ring 24, the number of push blocks 243 and stop blocks 242 can also be set to multiple, and correspondingly, multiple stop seats 121 are also provided on the lower housing 12. The specific number of stop blocks 242, push blocks 243, and stop seats 121 can be selected according to the actual needs of those skilled in the art; for example... Figure 3 and Figure 8 As shown, the specific configuration of the stop block 242, the push block 243, and the stop seat 121 can be set to three.

[0086] To facilitate understanding, the specific working process of the one-way locking assembly 2 will be described in detail below based on the specific structure of the one-way locking ring 24 described above. Since the rearview mirror has two working states—expanded and folded—and is generally in the folded state when the vehicle is locked, there is usually no scenario requiring manual forward folding. Therefore, the following description will take the manual forward folding of the rearview mirror in the unfolded state and the electric reset process after manual forward folding as examples. For ease of description, the left-side rearview mirror of the vehicle will be used as an example, i.e., in… Figures 11 to 20 In this case, the clockwise rotation of the lower housing 12 around the shaft seat 21 is the first direction a for manual forward folding, and the reverse is the second direction b for reset folding.

[0087] When the rearview mirror is in its normal unfolded state, such as Figure 11 As shown, at this time, the gear sleeve 23 engages with the limiting block 2211 of the limiting sleeve 221 through the limiting groove 230, so that the gear sleeve 23 is in a state of restricted rotation in the circumferential direction. Meanwhile, as... Figure 12 and Figure 13 As shown, the one-way locking ring 24 contacts the first abutting surface 2311 of the stop 231 on the outer side of the gear sleeve 23 through the second abutting surface 2411 of the inner locking part 241; the one-way locking ring 24 abuts against the stop 121 provided on the lower housing 12 through the outer stop 242. For ease of understanding, the interval angle between the stop 121 on the lower housing 12 and the push block 243 on the one-way locking ring 24 can be assumed to be α.

[0088] If the car is locked at this time, i.e., the rearview mirror needs to be electrically folded, the drive mechanism 3 can drive the drive gear 31 with the gear sleeve 23 installed. Since the gear sleeve 23 is in a circumferential limit state at this time, the gear sleeve 23 can remain stationary, and the drive mechanism 3, together with the housing, rotates counterclockwise in the second direction b around the shaft seat 21. During this process, the stop 121 on the lower housing 12 gradually moves away from the stop block 242 on the outside of the one-way locking ring 24, so that the one-way locking ring 24 is in a stationary state.

[0089] It should be noted that the angle from which the rearview mirror unfolds to when it is fully folded can be set as θ. If the interval angle α is less than θ, then after the rearview mirror automatically folds by an angle α, the lower housing 12 can abut against the push block 243 through the stop seat 121, thereby driving the one-way locking ring 24 to rotate synchronously along the second counterclockwise direction b by an angle of (θ-α) until the rearview mirror is fully folded.

[0090] like Figure 14As shown, assuming the rearview mirror is manually folded forward in its normally deployed state, that is, the housing along with the drive mechanism 3 rotates around the bearing 21 in the first direction a, and the angle of rotation can be set as β. For ease of understanding, we can assume that the position of the lower housing 12 is X1 when the rearview mirror is in its normally deployed state; and the position of the lower housing 12 is X2 after the rearview mirror has completed its manual folding forward, with the angle between position X1 and position X2 being β.

[0091] like Figure 12 , Figure 13 and Figure 15 As shown, during the rotation of the rearview mirror in the first direction a, because the one-way locking ring 24 abuts against the first abutting surface 2311 on the outside of the gear sleeve 23 through the second abutting surface 2411, the driving force on the gear sleeve 23 is greater than the set threshold, and thus the gear sleeve 23 disengages from the limiting sleeve 221 and rotates synchronously by an angle β along the first direction a. Figure 16 As shown, for ease of understanding, we can assume that when the rearview mirror is in its normal unfolded state, the position of the gear sleeve 23 relative to the limit sleeve 221 is Y1; then after the rearview mirror is manually folded forward, the position of the gear sleeve 23 relative to the limit sleeve 221 is Y2, and the interval angle between position Y1 and position Y2 is β.

[0092] It should be noted that during this process, the drive mechanism 3 can rotate synchronously with the housing, that is, the drive mechanism 3, the drive gear 31, and the gear sleeve 23 rotate synchronously to ensure that there is no transmission interference between the drive mechanism 3 and the gear sleeve 23.

[0093] It's important to know that, theoretically, the rearview mirrors should fold forward electrically when the car key is pressed. However, after the rearview mirrors are manually folded forward from the unfolded state, it's necessary to ensure that the rearview mirrors do not fold forward after the car key is pressed again, in order to ensure the safe use of the rearview mirrors.

[0094] In the technical solution of this application, after the rearview mirror is manually folded forward from its unfolded state, if the unlock button of the car key is pressed at this time, theoretically, the rearview mirror needs to perform a forward folding action, that is, the rearview mirror needs to rotate along the first direction a, that is, the drive mechanism 3 needs to drive the drive gear 31 to generate a tendency to rotate in the second direction b. Since the gear sleeve 23 is in a free state of circumferential rotation at this time, the rotation tendency of the drive gear 31 can be transmitted to the gear sleeve 23. During the manual forward folding process of the rearview mirror, the lower housing 12, the one-way locking ring 24 and the gear sleeve 23 rotate synchronously. Therefore, the one-way locking ring 24 still abuts against the stop 231 of the gear sleeve 23 through the locking part 241, and abuts against the stop seat 121 on the lower housing 12 through the stop block 242. Therefore, the rotation tendency of the lower housing 12 towards the one-way locking ring 24 along the first direction a is exactly abutted by the rotation tendency of the gear sleeve 23 towards the one-way locking ring 24 along the second direction b. At this time, the drive mechanism 3 and the gear sleeve 23 are locked by the one-way locking ring 24, causing the drive function of the drive mechanism 3 to fail. Then, after receiving the lock signal, the controller of the drive mechanism 3 can control the actuator to stop to ensure the functional safety of the rearview mirror.

[0095] If the rearview mirror is manually folded forward from its unfolded state and the car key's lock button is pressed, the drive mechanism 3 should apply a driving force along the first direction a to the drive gear 31 mounted on the gear sleeve 23; this allows the gear sleeve 23, under circumferential limitation, to react with the drive mechanism 3, along with the housing, to rotate around the shaft seat 21 along the second direction b. However, if... Figure 15 As shown, at this time, the gear sleeve 23 is in a free rotational state, disengaged from the limit, and the stop 231 of the gear sleeve 23 is in a released state from the locking part 241 of the one-way locking ring 24 in the first direction a. Therefore, the gear sleeve 23 will rotate along the first direction a under the drive of the drive mechanism 3 until the gear sleeve 23 re-engages with the limit sleeve 221; as Figure 16 As shown, the gear sleeve 23 is positioned at Y3 relative to the limiting sleeve 221. Assuming that the limiting sleeve 221 has multiple limiting grooves 230, and the interval angle between adjacent limiting grooves 230 is γ, then the rotation angle of the gear sleeve 23 from position Y2 to position Y3 is (γ-β).

[0096] like Figure 17As shown, during the rotation of the gear sleeve 23 from position Y2 to position Y3, both the one-way locking ring 24 and the lower housing 12 remain stationary (the lower housing 12 is positioned and engaged with the base 211). This causes the stop 231 on the outer side of the gear sleeve 23 to move away from the locking part 241 on the one-way locking ring 24 at position Y2 and move closer to position Y4 of another locking part 241 adjacent to the one-way locking ring 24 along the first direction a. At this time, the interval angle between positions Y3 and Y4 is β; at the same time, the position of the push block 243 on the one-way locking ring 24 can be set as Z1.

[0097] Because the gear sleeve 23 engages with the limiting sleeve 221 again at position Y3, circumferential rotation is restricted. Then, under the continued drive of the drive mechanism 3, since the gear sleeve 23 is stationary relative to the shaft seat 21, the drive mechanism 3, under the reaction force of the driving force, causes the housing to rotate around the shaft seat 21 in the second direction b. Figure 17 As shown, when the lower housing 12 rotates in the second direction b with the drive mechanism 3, the stop 121 on the lower housing 12 can move away from the stop block 242 outside the one-way locking ring 24; simultaneously, one of the stop 121 can move closer to the push block 243 outside the one-way locking ring 24. This continues until the lower housing 12 rotates by an angle α along the second direction b, as... Figure 18 As shown, the stop 121 on the lower housing 12, near the push block 243, is located at position Z1 and contacts the push block 243.

[0098] like Figure 20 As shown, with the continued driving of the drive mechanism 3, the lower housing 12 can continue to rotate along the second direction b. During this process, the lower housing 12 can abut against the push block 243 through the stop 121 to drive the one-way locking ring 24 to rotate synchronously. When the one-way locking ring 24 continues to rotate along the second direction b with the lower housing 12 until the push block 243 reaches position Z2, the interval angle between positions Z1 and Z2 is β. During this process, as... Figure 19 As shown, the locking part 241 at position Y4 on the one-way locking ring 24 can abut against the first pressing surface 2312 of the stop 231 at position Y3 on the gear sleeve 23 through the second pressing surface 2412. Under the pressing of the stop 231, the locking part 241 will drive the one-way locking ring 24 to undergo radial elastic deformation, so that the locking part 241 can pass over the stop 231. Then the one-way locking ring 24 can be deformed and reset. If the rearview mirror is not in the folded state at this time, the drive mechanism 3 can continue to drive the housing to rotate the rearview mirror in the second direction b until the rearview mirror is completely folded.

[0099] It should be noted that in the above description, it is assumed that the one-way locking ring 24 remains relatively stationary when there is no opposing driving force. In reality, the one-way locking ring 24 may rotate with the driving component (which can be the gear sleeve 23 or the lower housing 12) under the action of friction, but this does not affect the above-mentioned function of the one-way locking ring 24; it is only for the convenience of describing the above process.

[0100] Another aspect of this application provides a vehicle, in one preferred embodiment of which the one-way locking component 2 described above is included.
