Description

Technical Field

[0001] This application relates to the field of vehicle maintenance technology, and in particular to a rearview mirror folding device and a car wash machine. Background Technology

[0002] Car wash machines use roller-shaped brushes to automatically clean cars. The brushes are typically positioned vertically and mounted on either side of a gantry that moves back and forth along the length of the car from front to back, automating the cleaning of the car's sides. However, since rearview mirrors protrude from the sides of the car, the brushes can easily collide with and damage them when passing by.

[0003] In related technologies, to address the issue of rearview mirrors being damaged during car washing, the mirrors are typically folded and closed manually to reduce their protrusion. However, for driverless vehicles, the lack of driver intervention to fold and close the mirrors before the car enters the car wash, or the possibility of the car wash operator forgetting to close the mirrors due to negligence, means that the mirrors still face the risk of being damaged by collisions during the car wash process. Summary of the Invention

[0004] To solve at least one of the above-mentioned technical problems, this application provides a rearview mirror folding device and a car wash machine, which can first be centered with the vehicle and then actively close the rearview mirror. The technical solution adopted is as follows.

[0005] In a first aspect, this application discloses a rearview mirror folding device, including a synchronizing mechanism and two pressing members. The two pressing members are arranged laterally at intervals and can move relative to the vehicle longitudinally. The synchronizing mechanism has two connecting ends, and the two pressing members are respectively installed on the two connecting ends. The synchronizing mechanism drives the two connecting ends to move synchronously laterally and maintains a constant distance between the two connecting ends so that the two pressing members abut against the surfaces of the rearview mirrors on both sides to close the rearview mirrors. The resistance of the synchronizing mechanism when moving laterally is less than or equal to the closing resistance of the vehicle's rearview mirrors.

[0006] In some embodiments of this application, the synchronization mechanism includes a traction member and a tensioning member. The tensioning member is disposed on the gantry frame, and the traction member is movably wound around the tensioning member and tensioned. The two ends of the traction member are closedly connected, and the two connecting ends are disposed on the same side of the traction member.

[0007] In some embodiments of this application, the synchronization mechanism further includes two transversely arranged support beams, which are spaced laterally on the gantry frame. The tensioning member includes two inner pulleys and two outer pulleys. The two inner pulleys are respectively located at the inner ends of the two support beams, and the two outer pulleys are respectively located at the outer ends of the two support beams. The connecting end is located on the traction member between the inner and outer pulleys.

[0008] In some embodiments of this application, the tensioning member further includes a first roller and a second roller disposed on the crossbeam of the gantry frame. The first roller is used to wrap around the inner ring portion of the traction member, and the second roller is used to wrap around the outer ring portion of the traction member.

[0009] In some embodiments of this application, the gantry and the vehicle are movable relative to each other, and the rearview mirror folding device further includes a first slide rail, which is arranged laterally on the support beam, and the pressing member is slidably connected to the first slide rail.

[0010] In some embodiments of this application, the rearview mirror folding device further includes a mounting base and a second slide rail disposed on the mounting base. The second slide rail is disposed longitudinally, and the pressing member is slidably connected to the second slide rail. The mounting base includes a mounting part and a connecting part, which are arranged at an angle. The connecting part is slidably connected to the first slide rail, and the mounting part is connected to the second slide rail.

[0011] In some embodiments of this application, the rearview mirror folding device further includes a limiting component, which includes a limiting plate and a buffer. One of the mounting base and the pressing member is provided with a limiting plate, and the other is provided with a buffer. When the pressing member slides relative to the mounting base, the buffer abuts against the limiting plate.

[0012] In some embodiments of this application, the pressure member includes a guide segment and a closing segment connected to each other. The guide segment is disposed at the beginning end of the closing segment, and the closing segment is configured as an arc segment. The closing segment protrudes towards the pressure member on the opposite side. The closing segment is used to contact the rearview mirror and push the rearview mirror to fold. The distance between the guide segments of the two pressure members gradually increases in the direction away from the closing segment.

[0013] In some embodiments of this application, the pressing member further includes a retraction section, which is disposed at the end of the closing section away from the guide section, and the distance between the guide sections of the two pressing members gradually increases in the direction away from the closing section.

[0014] In some embodiments of this application, the surface of the pressure member for contacting the rearview mirror is configured as a curved surface that conforms to the surface contour of the rearview mirror, and the surface of the curved surface is provided with a flexible buffer structure.

[0015] Secondly, this application discloses a car wash machine, including a gantry frame and a rearview mirror folding device provided in the first aspect. The gantry frame includes two working columns arranged laterally, forming a passage for vehicles to pass through between the two working columns. A synchronization mechanism is installed on the gantry frame, and two connecting ends are respectively arranged on the two gantry frames. The gantry frame and the vehicle can move relative to each other longitudinally so that two pressing members abut against the surfaces of the rearview mirrors on both sides to close the rearview mirrors.

[0016] In some embodiments of this application, the car wash machine further includes a drive structure that drives the gantry to move longitudinally.

[0017] The aforementioned rearview mirror folding device and car wash machine utilize the synchronizing action of a synchronizing mechanism to drive the two contact points to move laterally synchronously, ensuring that the symmetrical planes of the two contact points coincide with the symmetrical plane of the vehicle. Without moving the vehicle, this achieves centered adjustment of the two contact points, ensuring that the distances between the two contact points and the rearview mirrors on both sides are equidistant. This helps the contact points better protect the rearview mirrors and improves the ease of use of both the contact points and the car wash machine. When the vehicle and the contact points move longitudinally relative to each other, the contact points provide a continuous pushing force to the rearview mirrors, creating a torque to fold and close the mirrors. This prevents drivers or car wash machine operators from forgetting to close the mirrors due to negligence, or in situations where a driver is unavailable to manually close the mirrors in an unmanned vehicle. It also prevents brush collisions from damaging the mirrors during the car wash process, improving the reliability of the car wash and the safety of the rearview mirrors. In this embodiment, the pulling force required to overcome the internal resistance when the synchronization mechanism moves laterally does not exceed the thrust required to overcome the damping force of the rearview mirror itself. This ensures that the folding device can operate in a manner that first performs centering adjustment and then closes the rearview mirror, ensuring that both rearview mirrors can close simultaneously under the action of the two side pressing parts, thereby improving the reliability of the rearview mirror folding device.

[0027] Please see Figure 1 The first aspect of this application provides a car wash machine, including a gantry 3000 and a rearview mirror folding device 1000. The gantry 3000 includes two working columns 3001 arranged laterally, forming a passage 1001 between the two working columns 3001 for a vehicle 2000 to pass through. The rearview mirror folding device 1000 is mounted on the gantry 3000, and the gantry 3000 and the vehicle 2000 can move relative to each other longitudinally. In this case, the rearview mirror folding device 1000 acts on the two rearview mirrors 2001 to close the rearview mirrors 2001. In this way, the rearview mirrors 2001 of the vehicle 2000 can be actively closed, avoiding situations where the driver or car wash machine operator forgets to close the rearview mirrors 2001 due to negligence, or where the driver of the unmanned vehicle 2000 lacks the ability to manually close the rearview mirrors 2001. This solves the problem of brushes colliding and damaging the rearview mirrors 2001 during the car wash process, improving the safety of the rearview mirrors 2001 during the car wash process and the reliability of the car wash machine.

[0028] Here, "lateral" refers to the width direction of the vehicle (e.g., 2000). Figure 1The x-direction shown is the distribution direction of the two rearview mirrors 2001 on the vehicle 2000. The longitudinal direction refers to the length of the vehicle 2000, that is, the direction perpendicular to the lateral direction. Figure 1 y direction shown.

[0029] It is understood that the relative longitudinal movement of the vehicle 2000 and the gantry 3000 can include the following methods: In the first example, the vehicle 2000 is stationary in the channel 1001, while the gantry 3000 moves longitudinally, causing the folding device 1000 to act on and pass over the surface of the rearview mirror 2001. Since the gantry 3000 of the car wash machine in the related art is usually equipped with brushes (not shown), and car washing is usually carried out by keeping the vehicle 2000 stationary while the gantry 3000 moves, the movement method of the first example requires less modification to the existing movement method of the gantry 3000, which helps to improve the adaptability of the rearview mirror folding device 1000 installation and use, and improves the safety of car washing. In the second example, the gantry 3000 remains stationary, and the vehicle 2000 passes longitudinally through the passage 1001 and over the rearview mirror folding device 1000. The folding device 1000 acts on the rearview mirror 2001 and passes over its surface. In the third example, the vehicle 2000 and the gantry 3000 can move simultaneously. Specifically, the vehicle 2000 moves forward, and the gantry 3000 moves from in front of the vehicle 2000 and toward the vehicle 2000. It can be seen that relative movement between the vehicle 2000 and the gantry 3000 can be achieved in all three examples. Therefore, this embodiment does not limit the specific movement method of the vehicle 2000 and the gantry 3000.

[0030] Taking the first example as an example, optionally, the car wash machine also includes a drive structure (not shown) that drives the gantry 3000 to move longitudinally. In this way, the vehicle 2000 can be stopped stably in the channel 1001, and the rearview mirror 2001 can be folded and the car wash process can be achieved by controlling the longitudinal movement of the gantry 3000.

[0031] Other components and operations of the car wash machine have been described in the relevant art to those skilled in the art, and will not be described in detail here. The structure of the rearview mirror folding device 1000 will be described below.

[0032] Please see Figures 1 to 3The second aspect of this application provides a rearview mirror folding device 1000 (hereinafter referred to as folding device 1000), which can be applied to a car wash machine. The folding device 1000 includes a synchronization mechanism 400 and two pressing members 100. The two pressing members 100 are arranged laterally at intervals, and the pressing members 100 and the vehicle 2000 can move relative to each other longitudinally. The synchronization mechanism 400 is provided with two connecting ends 421, and the two pressing members 100 are respectively installed on the two connecting ends 421. The synchronization mechanism 400 drives the two connecting ends 421 to move synchronously laterally, and keeps the distance between the two connecting ends 421 constant, so that the two pressing members 100 abut against the surfaces of the rearview mirrors 2001 on both sides to close the rearview mirrors 2001. The resistance of the synchronization mechanism 400 when moving laterally is less than the closing resistance of the rearview mirrors 2001 of the vehicle 2000.

[0033] Optionally, the synchronization mechanism 400 is mounted on the gantry 3000, and the two connecting ends 421 are respectively disposed on the two gantry 3000s. In this way, when the gantry 3000 moves relative to the vehicle 2000, the two pressing members 100 can respectively abut against the surface of the rearview mirrors 2001 on both sides to close the rearview mirrors 2001.

[0034] In this application, the synchronization mechanism 400 solves the problem of different distances between the two pressing members 100 and the two side mirrors 2001 when the vehicle 2000 is not parked in the center. During the use of the synchronization mechanism 400, due to the deviation of the vehicle 2000 in parking (e.g., parked to the left), the pressing member 100 on one side (e.g., the left side) is closer to the rearview mirror 2001 of the vehicle 2000 than the one on the other side (e.g., the right side). Therefore, the pressing member 100 on the left side can contact the left rearview mirror 2001 of the vehicle 2000, and the left rearview mirror 2001 has a lateral reaction force on the pressing member 100 on the left side. At this time, the synchronization mechanism 400 drives the pressing member 100 on the right side to move synchronously to the left so that the pressing member 100 on the right side can contact the right rearview mirror 2001. The synchronizing mechanism 400 maintains the distance between the two connecting ends 421 during lateral movement, ensuring that the distance between the two contact points 100 remains unchanged after the lateral movement, and that both can contact the surfaces of the side mirrors 2001. It is evident that the synchronizing mechanism 400 enables the two contact points 100 to move laterally synchronously, allowing the symmetrical planes of the two contact points 100 to coincide with the symmetrical plane of the vehicle 2000. This achieves centering adjustment of the two contact points 100 without moving the vehicle 2000, ensuring that the distances between the two contact points 100 and the side mirrors 2001 of the vehicle 2000 are equal. This helps the contact points 100 better protect the side mirrors 2001 and improves the ease of use of both the contact points 100 and the car wash machine.

[0035] After the two pressure points 100 are centered, they abut against the surfaces of the side mirrors 2001 on both sides of the vehicle 2000. This allows the pressure points 100 to provide a continuous pushing force to the side mirrors 2001 as the vehicle 2000 and the pressure points 100 move longitudinally relative to each other, thereby generating a torque to fold and close the side mirrors 2001. After the side mirrors 2001 are closed, the vehicle 2000 can pass through the passage 1001. The symmetrical arrangement of the two pressure points 100 ensures that the side mirrors 2001 on both sides of the vehicle 2000 can be folded and retracted simultaneously. This method allows the rearview mirrors 2001 of the vehicle 2000 to be automatically closed, thus preventing situations where the driver or car wash operator forgets to close the rearview mirrors 2001 due to negligence, or where the driverless vehicle 2000 lacks a driver to manually close the rearview mirrors 2001. It also prevents the rearview mirrors 2001 from protruding too much on the side of the vehicle due to not being closed, which could cause the brush to collide and damage the rearview mirrors 2001 during the car wash process. This improves the reliability of the car wash and the safety of the rearview mirrors 2001.

[0036] In this embodiment, the torque exerted by the pressing member 100 when closing the rearview mirror 2001 is generated by the relative movement between the vehicle 2000 and the pressing member 100 mounted on the gantry 3000. That is, utilizing the self-driving force of the vehicle 2000 moving forward or the self-driving force of the gantry 3000 moving longitudinally (or both driving forces), this longitudinal force is converted into a torque that pushes the rearview mirror 2001 to rotate and close when the pressing member 100 abuts against it. Therefore, by adopting the arrangement of this application, a thrust can be generated to close the rearview mirror 2001 without introducing other lateral power mechanisms or control systems, thereby automatically closing and retracting the rearview mirror 2001. This simplifies the structural design of the car wash machine, does not affect the original car wash process, and improves the reliability of the car wash machine.

[0037] It should be noted that the following problem may occur during the use of the rearview mirror folding device 1000: one of the rearview mirrors 2001 on the vehicle 2000 closes under the pushing force of the pressing member 100, but the other rearview mirror 2001 fails to close. At this time, the pressing member 100 has already passed the vehicle 2000 and cannot close the rearview mirror 2001 again, resulting in both rearview mirrors 2001 failing to close at the same time. The reason for this phenomenon is that one of the rearview mirrors 2001 (e.g., the left side) of the vehicle 2000 comes into contact with the pressing member 100 on one side (e.g., the left side), but the pushing force of the left rearview mirror 2001 on the pressing member 100 is insufficient to push the synchronizing mechanism 400 to move laterally. Therefore, the synchronizing mechanism 400 cannot be centered, which causes the pressing member 100 on the other side (right side) to be unable to approach and contact the other side (right side) rearview mirror 2001. At the same time, the left rearview mirror 2001 folds and closes under the pushing force of the left pressing member 100. This results in the left rearview mirror 2001 closing but the right rearview mirror 2001 not closing.

[0038] To address this issue, this embodiment ensures that the resistance of the synchronizing mechanism 400 during lateral movement is less than or equal to the closing resistance of the rearview mirror 2001 of the vehicle 2000. The resistance during lateral movement of the synchronizing mechanism 400 primarily originates from the friction between internal components of the synchronizing mechanism 400 and the friction between the synchronizing mechanism 400 and the gantry 3000. The closing resistance of the rearview mirror 2001 primarily originates from the damping force of the internal rotating shaft of the rearview mirror 2001, which is used to ensure that the rearview mirror 2001 remains deployed during normal use of the vehicle 2000. Therefore, in this embodiment, the pulling force required to overcome the internal resistance when the synchronizing mechanism 400 moves laterally does not exceed the pushing force required to overcome the damping force of the rearview mirror 2001 itself. This allows the synchronizing mechanism 400 to be pushed laterally by one of the rearview mirrors 2001 before it is closed, enabling centering adjustment until the other side's pressing member 100 also contacts the rearview mirror 2001. At this point, the pushing force of the pressing member 100 closes both rearview mirrors 2001 simultaneously. This arrangement ensures that the folding device 1000 operates by first centering and then closing the rearview mirrors 2001, ensuring that both rearview mirrors 2001 close simultaneously under the action of the pressing members 100 on both sides, thus improving the reliability of the rearview mirror folding device 1000.

[0039] Therefore, it is particularly important to reduce the internal resistance of the synchronization mechanism 400 and the friction between the synchronization mechanism 400 and the gantry 3000. The following will further explain different implementations of the synchronization mechanism 400.

[0040] In some embodiments, please combine Figure 1 , Figure 3 and Figure 4 The synchronization mechanism 400 includes a traction member 430 and a tensioning member 440. The tensioning member 440 is mounted on the gantry 3000. The traction member 430 is movably wound around the tensioning member 440 and tensioned. The two ends of the traction member 430 are closedly connected, and the two connecting ends 421 are located on the same side of the traction member 430. For example, the traction member 430 can be a rope structure, such as a single steel wire, a multi-strand steel wire rope, a fiber rope, a chain, or a belt. The tensioning member 440 tensions the traction member 430, giving it internal tension. The connecting end 421 on one side can use this internal tension to drive the connecting end 421 on the other side to move laterally, thereby achieving synchronous linkage between the two connecting ends 421. Because the two ends of the traction member 430 are closedly connected, the traction member 430 forms a closed-loop structure. The tensioning element 440 may be at least two rollers that can rotate freely or be fixed, and the traction element 430 is sequentially wound around the outer circumference of the two rollers. The same side of the traction element 430 refers to the same side located on the line connecting the axes of the two rollers.

[0041] In some embodiments, the synchronization mechanism 400 further includes two transversely arranged support beams 422, which are laterally spaced on the gantry 3000, for example, on the working column 3001 of the gantry 3000. The installation height is adjusted according to the actual height of the rearview mirror 2001 of the vehicle 2000. The tensioning member 440 includes two inner pulleys 441 and two outer pulleys 442. The two inner pulleys 441 are respectively disposed on the inner ends of the two support beams 422, and the two outer pulleys 442 are respectively disposed on the outer ends of the two support beams 422. The connecting end 421 is disposed on the traction member 430 between the inner pulleys 441 and the outer pulleys 442. The support beam 422 has two opposite ends, with the inner end being the end of the support beam 422 closer to the opposite connecting end 421 and the outer end being the end away from the opposite connecting end 421. Each support beam 422 is equipped with an inner pulley 441 and an outer pulley 442, forming a tensioned traction member 430 between them. Therefore, the connecting end 421 is positioned on the traction member 430 between the inner and outer pulleys 441 and 442. This allows the connecting end 421 to move laterally between the inner and outer pulleys 441 and 442, ensuring that both sides of the connecting end 421 have the same direction and amplitude of movement. Furthermore, the distance between the inner and outer pulleys 441 and 442 limits the lateral travel of the connecting end 421, preventing it from slipping out of the inner and outer pulleys. This arrangement facilitates control of the range of motion of the connecting ends 421 on both sides and improves the stability of the lateral movement of the connecting end 421.

[0042] In some embodiments, the tensioning member 440 further includes a first roller 443 and a second roller 444 disposed on the crossbeam 3002 of the gantry 3000. The first roller 443 is used to wrap around the inner ring portion 431 of the traction member 430, and the second roller 444 is used to wrap around the outer ring portion 432 of the traction member 430. Since the vehicle 2000 needs to pass between the two pressure points 100 on both sides or park between the two pressure points 100 on both sides when using the car wash machine, that is, the gap between the two pressure points 100 on both sides forms a passage 1001 for the vehicle 2000 to pass through or park. In actual use, it is necessary to ensure that the passage 1001 is unobstructed and unobstructed. Therefore, two casters are used to lift the traction component 430 vertically. This allows the traction component 430 to cross the passage 1001 from above the vehicle 2000, preventing it from obstructing the passage 1001 or interfering with the vehicle 2000, thus improving the reliability of the car wash machine. Since the same side of the traction component 430 moves in the same direction when rotating, while the opposite side moves in opposite directions, the first caster 443 and the second caster 444 respectively support the inner and outer ring portions 432 of the traction component 430, preventing interference between the two directions of movement. The inner ring portion 431 refers to the part of the traction component 430 connecting the inner sides of the two inner pulleys 441, and the outer ring portion 432 refers to the part of the traction component 430 connecting the outer sides of the two outer pulleys 442.

[0043] In some embodiments, the tensioning member 440 includes two first rollers 443 and two second rollers 444. The two first rollers 443 are respectively disposed at both ends of the crossbeam 3002 of the gantry frame 3000, and the two second rollers 444 are respectively disposed at both ends of the crossbeam 3002 of the gantry frame 3000. The first rollers 443 and the second rollers 444 located at the same end of the crossbeam 3002 of the gantry frame 3000 have collinear axes of rotation. The two first rollers 443 make the shape of the inner ring portion 431 of the traction member 430 more closely fit the shape of the crossbeam 3002 of the gantry frame 3000. Similarly, the two second rollers 444 make the shape of the outer ring portion 432 of the traction member 430 more closely fit the shape of the crossbeam 3002 of the gantry frame 3000, increasing the clearance space under the gantry frame 3000 and preventing the traction member 430 from obstructing or occupying the space above the passage 1001. The first roller 443 and the second roller 444 located at the same end of the crossbeam 3002 of the gantry 3000 are arranged with their shafts collinear. For example, the first roller 443 and the second roller 444 are arranged longitudinally. This allows the inner ring portion 431 and the outer ring portion 432 of the traction member 430 to overlap more on the crossbeam 3002 of the gantry 3000, further reducing the space occupied by the passage 1001 and making the structure of the synchronization mechanism 400 more compact.

[0044] In some embodiments, please refer to Figure 5 The gantry 3000 and the vehicle 2000 are movable relative to each other. The rearview mirror folding device 1000 also includes a first slide rail 423, which is laterally mounted on the support beam 422. The pressing member 100 is slidably connected to the first slide rail 423. The first slide rail 423 enables the pressing member 100 to slide against the support beam 422, reducing friction and improving the smoothness of its lateral movement. Furthermore, the first slide rail 423 provides guidance and support for the movement of the pressing member 100, increasing its support strength, reducing vibration during lateral movement, and improving its stability. Optionally, a slider can be provided on the pressing member 100 to engage with the first slide rail 423. Alternatively, the first slide rail 423 can be replaced with an optical shaft or channel steel, and linear bearings, grooved wheels or balls can be correspondingly provided on the pressure member 100 for connection.

[0045] In some embodiments, the rearview mirror folding device 1000 further includes a mounting base 210 and a second slide rail 220 disposed on the mounting base 210. The second slide rail 220 is arranged longitudinally, and the pressing member 100 is slidably connected to the second slide rail 220. The mounting base 210 includes a mounting portion 211 and a connecting portion 212, which are arranged at an angle. The connecting portion 212 is slidably connected to the first slide rail 423, and the mounting portion 211 is connected to the second slide rail 220. By utilizing the angled mounting portion 211 and the connecting portion 212, connections with the sliding guide and the rearview mirror 2001 protective structure can be realized in different directions of the mounting base 210, respectively, avoiding interference between the rearview mirror 2001 protective structure and the sliding guide, making the entire synchronization mechanism 400 structure simpler and more compact. Optionally, the mounting part 211 and the connecting part 212 are arranged perpendicular to each other. For example, the connecting part 212 is arranged vertically, and the mounting part 211 is arranged horizontally at the lower end of the connecting part 212. An angle bracket is provided between the mounting part 211 and the connecting part 212 for reinforcement, which helps to improve the strength of the mounting base 210.

[0046] Optionally, the mounting base 210 is also provided with a mounting pin 413, which is detachably connected to the connecting part 212. The traction member 430 is fixedly connected to the mounting pin 413. Setting the traction member 430 on the mounting pin 413 facilitates the connection between the traction member 430 and the mounting base 210. For example, the mounting pin 413 can be a screw, and the mounting base 210, for example, the connecting part 212, can have a screw hole. The screw can be bolted into the screw hole, and the traction member 430 can be wound and fixed to the screw. This simplifies the connection or disassembly of the traction member 430 and the mounting base 210, improving the ease of assembly of the synchronization mechanism 400. Furthermore, the detachable connection between the mounting pin 413 and the connecting part 212 allows the mounting pin 413 to be fixed to the connecting part 212 after the traction member 430 has been wound around it, facilitating flexible adaptation to installation operations in different scenarios. Of course, in other alternative embodiments, the mounting nail 413 can be replaced by a fixing block, fixing hole, fixing rod, etc., and the traction member 430 can be fixed by means of bonding, binding, wrapping, welding, bolting, etc., which are not limited here.

[0047] By setting a second longitudinal slide rail 220, the pressing member 100 and the gantry 3000 can be slidably connected longitudinally. In this way, when the gantry 3000 passes the vehicle 2000 longitudinally, the pressing member 100 abuts against the rearview mirror 2001 of the vehicle 2000. According to the principle of action and reaction, the rearview mirror 2001 of the vehicle 2000 will also exert a pushing force on the pressing member 100, causing the pressing member 100 to slide in the opposite direction. Therefore, the reverse sliding of the pressure member 100 can buffer the rearview mirror 2001. This buffering effect not only transforms the impact force generated when the pressure member 100 contacts the rearview mirror 2001 into the reverse sliding of the pressure member 100, helping to avoid damage to the rearview mirror 2001 caused by the impact force, but also prolongs the contact time between the pressure member 100 and the rearview mirror 2001 during the passage of the gantry 3000 over the vehicle 2000, allowing the pressure member 100 to slowly push the rearview mirror 2001, thereby improving the stability and reliability of the rearview mirror 2001 during the rotation and folding process. Optionally, a slider 150 or a pulley can be provided on the pressure member 100, and the slider 150 is connected to the second slide rail 220 to achieve a sliding connection between the pressure member 100 and the mounting base 210. Alternatively, in other alternative embodiments, a slider can be provided on the mounting base 210, and the second slide rail 220 can be provided on the pressure member 100, with the slider or pulley connected to the slide rail. For example, the slide rail can be replaced with an optical shaft, channel steel, etc., and the corresponding slider can be replaced with a linear bearing, grooved wheel, ball bearing, etc.

[0048] In some embodiments, the rearview mirror folding device 1000 further includes a limiting component 300, which includes a limiting plate 310 and a buffer 320. One of the mounting base 210 and the pressing member 100 is provided with the limiting plate 310, and the other is provided with the buffer 320. When the pressing member 100 slides relative to the mounting base 210, the buffer 320 abuts against the limiting plate 310. By providing the limiting component 300, on the one hand, the longitudinal travel of the pressing member 100 can be limited, preventing the limiting member from dislodging from the second slide rail 220 and improving the reliability of the pressing member 100 in cooperation with the mounting base 210; on the other hand, the buffer 320 can further provide a buffering effect when the pressing member 100 abuts against the rearview mirror 2001, thereby reducing the impact force at the moment of contact between the pressing member 100 and the rearview mirror 2001, and protecting the rearview mirror 2001.

[0049] For example, the limiting plate 310 can be disposed on the mounting base 210, and the buffer 320 can be disposed on the contact member 100, such as Figure 5 As shown. In other examples, the limiting plate 310 may also be provided on the pressure member 100 and the buffer 320 may be provided on the mounting base 210, but this embodiment is not limited to this.

[0050] Optionally, the buffer 320 may be a damper, an elastic column, an elastic block, a spring, a sheet, etc.

[0051] Optionally, two limit plates 310 can be provided, spaced apart longitudinally, and the longitudinal travel of the contact member 100 is the distance between the two limit plates 310. In some examples, the two limit plates 310 can be provided on the same side of the slide rail in the transverse direction, in which case a buffer 320 can be provided, with its two ends abutting against the two limit plates 310 respectively. Of course, two buffers 320 can also be provided, with each buffer 320 corresponding to one of the two limit plates 310. In other examples, the two limit plates 310 can be provided on opposite sides of the slide rail in the transverse direction, in which case two buffers 320 can be provided, with each buffer 320 located on opposite sides of the slide rail and corresponding to one of the limit plates 310.

[0052] The following is Figure 2Taking the illustrated embodiment as an example, the process of the vehicle 2000 entering the gantry 3000 and interacting with the synchronization mechanism 400 will be explained. The traction member 430 is a steel wire, with one end fixed to a mounting pin 413 (e.g., a mounting pin 413 on the right support beam 422). The steel wire and mounting pin 413 can be fixed by wrapping or binding, and after being fixed, they do not move relative to each other. First, the steel wire sequentially passes over the inner pulley 441, the two first rollers 443, and the inner pulley 441 on the other side support beam 422, finally wrapping and fixing to the mounting pin 413 on the left support beam 422. This steel wire constitutes the inner ring portion 431 of the traction member 430. Next, the steel wire continues to pass over the outer pulley 442 on the left support beam 422 and the two second rollers 444, finally wrapping and fixing to the mounting pin 413 on the right support beam 422. This steel wire constitutes the outer ring portion 432 of the traction member 430. The inner ring portion 431 and the outer ring portion 432 constitute a complete closed loop of the traction member, and the closed-loop traction member 430 can maintain internal tension. Optionally, the inner ring portion 431 and the outer ring portion 432 can each use two steel wires, with the two steel wires connected end to end to form a closed loop, or they can be constructed using a single steel wire, with the single steel wire connected end to end to form a closed loop; no specific limitation is made here.

[0053] When the vehicle enters the gantry and parks between the two support beams 422, it may be parked slightly to the left or right. Taking parking slightly to the left as an example, after the vehicle stops, the left rearview mirror is closer to the left-side contact element in the lateral direction, while the right rearview mirror is farther from the right-side contact element. At this time, the gantry is parked in front of the vehicle. When the gantry starts working, it begins to move towards the vehicle. The vehicle's left rearview mirror first contacts the contact element 100 and generates a leftward thrust on the contact element 100. After being pushed, the contact element moves the left-side connecting end 421 and mounting pin 413 to the left. The left-side mounting pin 413 pulls the closed-loop steel wire along... Figure 3 The clockwise rotation of the device causes the right mounting pin 413 to move to the left. The right mounting pin 413 then moves the right connecting end 421 and the pressing member 100 to the left. Since the total length of the traction member 430 is constant, the lateral movement amplitude and direction of the right mounting pin 413 are the same as those of the left mounting pin 413. This continues until the right pressing member 100 also abuts against the rearview mirror surface. At this point, the synchronization mechanism 400 completes the centering adjustment, allowing the symmetrical planes of the two pressing members to move laterally until they coincide with the symmetrical plane of the vehicle. This facilitates the pressing member's subsequent closing of the rearview mirrors on both sides of the vehicle.

[0054] The combination of a traction member 430 and a tensioning member 440 in the synchronization mechanism 400 helps reduce the overall weight of the synchronization mechanism 400 and reduce internal friction. For example, the traction member 430 can be made of steel wire, and the tensioning member 440 can be made of pulleys. Compared with other configurations, steel wire and pulleys are lighter. Therefore, the resistance of the two side contact members 100 during lateral adjustment is reduced, and the movement is smoother. This reduces the occurrence of problems such as jamming or excessive resistance preventing lateral movement in the synchronization mechanism 400, and improves the reliability of the synchronization mechanism 400.

[0055] The structure and function of the pressure-sensitive element 100 will be further explained below.

[0056] In some embodiments, please combine Figures 6 to 8 The pressure-sensitive element 100 includes a guide section 120 and a closing section 110 connected to each other. The guide section 120 is disposed at the starting end of the closing section 110. The closing section 110 is configured as an arc-shaped section, protruding towards the pressure-sensitive element 100 on the opposite side. The closing section 110 is used to contact the rearview mirror 2001 and push the rearview mirror 2001 to fold. The distance between the guide sections 120 of the two pressure-sensitive elements 100 gradually increases in the direction away from the closing section 110. Thus, as Figure 8 As shown, the distance between the closed sections 110 of the two pressing members 100 gradually decreases along the y-axis. This allows the pressing members 100 to contact the rearview mirror 2001 and remain in contact with it as the gantry 3000 approaches the vehicle 2000 longitudinally. Since the closed section 110 is designed as an arc segment, meaning that the slope of the closed section 110 is different at each position, this slope variation setting allows the closed section 110 to adapt to the change in the contact angle between the rearview mirror 2001 and the closed section 110 during the folding and closing process. This ensures that the pressing members 100 exert a continuous pushing force on the rearview mirror 2001, guiding the rearview mirror 2001 to continuously rotate, fold, and ultimately close and retract. In this way, during the entire process of closing the rearview mirror 2001, the force of the pressing member 100 is distributed more evenly over time, avoiding excessive force when the pressing member 100 first contacts the rearview mirror 2001 or insufficient force in the later stage of contact, thus improving the stability of the rearview mirror 2001 folding process.

[0057] The starting end of the closed section 110 refers to the end of the closed section 110 facing the vehicle 2000 as the gantry 3000 approaches the vehicle 2000. That is, except at the connection between the closed section 110 and the guide section 120, the inclination angle β of the second inclined surface 121 on the guide section 120 is greater than the inclination angle α of any point on the closed section 110. Here, the inclination angle α of any point on the closed section 110 refers to the angle between any point on the closed section 110 and the longitudinal direction, and the inclination angle β of the second inclined surface 121 refers to the angle between the second inclined surface 121 and the longitudinal direction. Thus, the distance between the guide sections 120 of the two pressing members 100 is greater than the distance between the two closed sections 110, that is, a funnel-shaped opening is formed between the pressing members 100 on both sides, such as... Figure 8 As shown, the opening of the guide section 120 is larger than the opening of the closing section 110. During the longitudinal movement of the gantry 3000 towards the vehicle 2000, the rearview mirror 2001 of the vehicle 2000 passes sequentially through the guide section 120 and the closing section 110. Because the distance between the two guide sections 120 is larger, this distance allows for lateral parking deviation of the vehicle 2000 and provides sufficient space for lateral centering adjustment of the contact member 100 and the vehicle 2000. During the adjustment process, one side of the rearview mirror 2001 of the vehicle 2000 abuts against the guide section 120 of the contact member 100 on the same side. The rearview mirror 2001 exerts an outward pushing force on the guide section 120. This pushing force, through the centering mechanism, causes the contact member 100 on the other side to move laterally inward until the closing sections 110 of both contact members 100 contact the surfaces of both rearview mirrors 2001. Therefore, the guide section 120 serves to guide the two pressing members 100 in lateral centering adjustment. During the adjustment process, the contact area between the rearview mirror 2001 and the pressing member 100 gradually transitions from the guide section 120 to the closing section 110, realizing the lateral adjustment of the folding device 1000 and the function of pushing the rearview mirror 2001 to close. Utilizing the inclined design of the closing section 110, as the gantry 3000 approaches the vehicle 2000 longitudinally, the pressing member 100 contacts the rearview mirror 2001 and continues to adhere to it as the rearview mirror 2001 rotates, ensuring that the pressing member 100 has a continuous pushing force on the rearview mirror 2001, guiding the rearview mirror 2001 to continuously rotate, fold, and finally close and retract. In this way, during the entire process of closing the rearview mirror 2001, the force of the pressing member 100 is distributed more evenly over time, avoiding excessive force when the pressing member 100 first contacts the rearview mirror 2001 or insufficient force in the later stage of contact, thus improving the stability of the rearview mirror 2001 folding process.

[0058] In some embodiments, the guide segment 120 and the closing segment 110 are tangentially connected. This allows for a smooth connection between the guide segment 120 and the closing segment 110, making the movement of the rearview mirror 2001 from the guide segment 120 to the closing segment 110 smoother. It is understood that the tangential connection between the guide segment 120 and the closing segment 110 means that at the point where the guide segment 120 and the closing segment 110 connect, the tangent line of the closing segment 110 at that location coincides with the tangent line of the guide segment 120 at that location.

[0059] In some embodiments, the pressing member 100 further includes a retraction section 130, which is disposed at the end of the closing section 110 away from the guide section 120. The distance between the retraction sections 130 of the two pressing members 100 gradually increases in the direction away from the closing section 110. Thus, the distance between the retraction sections 130 of the two pressing members 100 is greater than the distance between the two closing sections 110; that is, a funnel-shaped opening is formed between the two pressing members 100, and the opening of the retraction section 130 is larger than the opening of the closing section 110. When passing through the guide section 120, closing section 110, and retraction section 130 in sequence, the distance between the two pressing members 100 undergoes a process of decreasing and then increasing again. The entire folding device 1000 exhibits a characteristic where the distance between the two pressing members 100 is larger at both ends and smaller in the middle. After passing vehicle 2000, gantry 3000 is positioned behind vehicle 2000. Since gantry 3000 usually needs to move back and forth longitudinally during the car wash process to wash the sides of the vehicle body multiple times, it needs to move back to the front of vehicle 2000. Alternatively, after the car wash is completed, gantry 3000 moves back to the front of vehicle 2000. During the movement of the gantry 3000, the pressure member 100 may experience slight lateral displacement due to minor vibrations. Therefore, during the retraction of the gantry 3000, the opening shape formed by the retraction sections 130 of the two pressure members 100 allows for the error caused by slight lateral displacement of the pressure member 100. At this time, the pressure member 100 can pass by the rearview mirror 2001, ensuring that the pressure member 100 retracts smoothly and preventing the pressure member 100 from getting stuck or bumping into the rearview mirror 2001 of the vehicle 2000, thus improving the safety of the pressure member 100 when retracting in the opposite direction.

[0060] In some embodiments, the retractable segment 130 and the closed segment 110 are tangentially connected. This allows for a smooth connection between the retractable segment 130 and the closed segment 110, avoiding an abrupt turn at the connection point that would increase the risk of collision with the rearview mirror 2001. It is understood that a tangential connection between the retractable segment 130 and the closed segment 110 means that at the point where the retractable segment 130 and the closed segment 110 connect, the tangent line of the closed segment 110 at that location coincides with the tangent line of the retractable segment 130 at that location.

[0061] In some embodiments, please refer to Figure 7 The guide section 120 has a second inclined surface 121, and the retraction section 130 has a third inclined surface 131. The inclination angle β of the second inclined surface 121 is greater than the inclination angle θ of the third inclined surface 131. The inclination angle β of the second inclined surface 121 refers to the angle between the second inclined surface 121 and the longitudinal direction, and the inclination angle θ of the third inclined surface 131 refers to the inclination angle between the third inclined surface 131 and the longitudinal direction. Because the guide section 120 needs to guide the lateral movement of the pressing member 100 to center and align the vehicle 2000 and the folding section laterally, the opening formed by the guide section 120 is larger to accommodate parking deviations of the vehicle 2000. The retraction section 130, after the lateral centering adjustment of the pressing member 100 and the vehicle 2000 has been completed, accommodates the slight lateral displacement of the pressing member 100 caused by the reciprocating motion of the gantry 3000. Therefore, the opening formed by the retraction section 130 can be set to be smaller than the opening of the guide section 120. This helps to make the structure of the entire pressure-sensitive element 100 more compact while still fulfilling the functions of the guiding section 120, the closing section 110, and the retraction section 130.

[0062] Optionally, the length of the guide segment 120 is greater than the length of the return segment 130, or the longitudinal projection length of the guide segment 120 is greater than the longitudinal projection length of the return segment 130.

[0063] Of course, in other alternative embodiments, the length and tilt angle of the retraction section 130 can be exactly the same as those of the guide section 120. That is, in the same pressing member 100, the retraction section 130 and the guide section 120 are symmetrically arranged about the closing section 110. In this way, the folding device 1000 can be installed on the gantry 3000 without distinguishing the direction. When in use, the folding device 1000 can be compatible with both the forward and reverse parking directions of the vehicle, thus improving the convenience of installing the folding device 1000.

[0064] In some embodiments, please refer to Figure 9 The surface of the pressure-sensitive element 100 that contacts the rearview mirror 2001 is configured as a curved surface 140 that matches the surface contour of the rearview mirror 2001, and the surface of the curved surface 140 is provided with a flexible buffer structure. This increases the contact area between the pressure-sensitive element 100 and the rearview mirror 2001, allowing the outer, top, and bottom surfaces of the rearview mirror 2001 to be completely covered by the pressure-sensitive element 100. This results in more uniform and stable force distribution during the contact process between the pressure-sensitive element 100 and the rearview mirror 2001, and more stable rotation and folding of the rearview mirror 2001 during closing, preventing damage to the rearview mirror 2001 and improving the reliability of the pressure-sensitive element 100.

[0065] In some embodiments, the surface of the curved surface 140 is provided with a flexible cushioning structure, such as a velvet cloth, a flexible or elastic pad (e.g., a rubber pad, a sponge pad), etc. This helps to further improve the fit between the curved surface 140 and the surface of the rearview mirror 2001, improve the wrapping effect of the curved surface 140 on the rearview mirror 2001, and reduce the risk of damage to the surface of the rearview mirror 2001.

[0066] In some embodiments, the curved surface 140 is provided with a slider, which includes at least one of a pulley or a ball, and the slider is used to contact the rearview mirror 2001. The pulley or ball structure can slide in contact with the surface of the rearview mirror 2001, reducing the friction with the rearview mirror 2001, thereby reducing the risk of damage to the surface of the rearview mirror 2001. Optionally, one type of pulley or ball can be provided on the curved surface 140, or a combination of pulleys or balls can be provided.

[0067] The following combination Figure 10 The interaction between the folding device 1000 and the rearview mirror 2001 in one embodiment will be described. The pressing member 100 includes a guide section 120, a closing section 110, and a retracting section 130 arranged sequentially. As the gantry gradually approaches the vehicle, the rearview mirror 2001 on one side of the vehicle ( Figure 10 (The middle part is the right rearview mirror) Contact guide section 120, such as Figure 10 As shown in (a). During the continuous movement of the gantry, the rearview mirror 2001 exerts a rightward reaction force on the right-side pressing member 100, causing the pressing member 100 to move laterally to the right, so that the other pressing member (left-side pressing member) abuts against the surface of the left-side rearview mirror. At this time, the pressing member 100 continues to move longitudinally until it slides to the closed section 110 and contacts the vehicle rearview mirror 2001, as shown in (a). Figure 10 As shown in (b), the force generated when the gantry moves has a lateral component in the closed section 110. This lateral component can serve as the force to push the rearview mirror to rotate and close. Under the thrust of the closed section 110, the rearview mirror rotates until it closes, as shown in (b). Figure 10 As shown in (c).

[0068] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
