Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and in particular to a rearview mirror and a vehicle. Background Technology

[0002] With the rapid development of the automotive industry and the increasing demands for driving comfort and safety, the importance of rearview mirror cleaning systems is becoming increasingly prominent. As a crucial window for drivers to observe the situation behind them, the cleanliness of the rearview mirror directly affects driving safety. If the rearview mirror is covered in dirt, the driver's vision will be severely impaired, potentially leading to the inability to promptly spot vehicles or pedestrians behind, increasing the risk of traffic accidents. Based on this, some rearview mirror cleaning solutions exist, equipped with nozzles that spray water or air onto the mirror surface for cleaning. These nozzles can be driven by a power unit to adjust the cleaning area. However, these technologies typically use an electric motor to drive the nozzle movement, requiring corresponding circuitry and increasing costs. Utility Model Content

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0024] As mentioned earlier, motors are typically used as the power source to drive the nozzles, requiring corresponding circuitry and increasing costs. Therefore, this invention proposes a rearview mirror with a cleaning component. The cleaning component's power source can use the cleaning medium as a power source to drive the nozzles, thus eliminating the need for a separate circuit structure and reducing costs. The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details.

[0025] Reference Figure 1 The rearview mirror 10 of the first embodiment of this utility model includes a housing 100, a mirror body 200, and a cleaning component 300. The mirror body 200 is connected to the housing 100 and has a mirror surface 201 facing outward. Specifically, the housing 100 and the mirror body 200 define an installation space, and the cleaning component 300 is located in the installation space and connected to the housing 100.

[0026] The cleaning assembly 300 includes a nozzle 310 and a power unit 320. The nozzle 310 sprays a cleaning medium onto the mirror surface 201. The cleaning medium, with a certain pressure and velocity, is sprayed from the nozzle 310 onto the mirror surface 201, thereby rinsing and cleaning the mirror surface 201. The power unit 320 drives the nozzle 310 to move, so that the nozzle 310 sprays the cleaning medium onto different areas of the mirror surface 201. In some scenarios, the nozzle 310 can rotate about an axis parallel to the mirror surface 201 to adjust the spray direction and angle with the mirror surface 201. In other scenarios, the nozzle 310 is positioned on the mirror surface 201 and can rotate about an axis perpendicular to the mirror surface 201, so that the nozzle can clean the mirror surface 201 along a circumferential trajectory.

[0027] In this embodiment, refer to Figure 5 The cleaning assembly 300 also includes a transmission conduit 340, which is connected to both the nozzle 310 and the power unit 320. The transmission conduit 340 is configured to transport cleaning media, with a portion of the cleaning media being sprayed out through the nozzle 310 to clean the mirror surface 201, and another portion being supplied to the power unit 320 to drive the nozzle 310 to move relative to the mirror surface 201. Thus, the power unit 320 uses the cleaning media as its power source, meaning it is a non-electrically driven power unit, eliminating the need for a corresponding circuit structure and helping to reduce costs.

[0028] It should be noted that the cleaning medium can come from the vehicle. For example, the cleaning medium is set as a gas, that is, the nozzle 310 cleans the mirror 201 by spraying air. This gas comes from the vehicle's air source, such as an air pump used to provide compressed air to the vehicle's air springs. Correspondingly, the power unit 320 is selected as a pneumatic device, such as a telescopic cylinder or a rotary cylinder.

[0029] For example, the cleaning medium is set to a liquid, meaning the nozzle 310 cleans the mirror surface 201 by spraying liquid, which originates from the vehicle's liquid storage container. Correspondingly, the power unit 320 is selected as a hydraulic device, such as a hydraulic motor. It should be noted that when the cleaning medium is set to a liquid, a liquid recovery pipeline can also be installed inside the rearview mirror to recover the liquid back to the liquid storage container, achieving liquid recycling. Furthermore, the liquid storage container can also be equipped with a filter to filter the recovered liquid.

[0030] The cleaning medium can also come from an external source. For example, the cleaning medium can be a gas, and the source can be a gas cylinder or an air pump that is independent of the vehicle. For example, the cleaning medium can be a liquid, and the source can be a liquid reservoir that is independent of the vehicle.

[0031] Based on the first embodiment, in some embodiments of this utility model, reference is made to Figure 5 The transmission pipeline 340 includes a main pipe 344 and a branch pipe 345 connected to the main pipe 344. The main pipe 344 is provided with an inlet 343 and a first outlet 341, and the branch pipe 345 is provided with a second outlet 342. The inlet 343 is used to allow cleaning media from the vehicle to enter the main pipe 344. For example, when the cleaning media is gas, the inlet 343 is connected to the vehicle's air source; when the cleaning media is liquid, the inlet 343 is connected to the vehicle's liquid storage container. The second outlet 342 is connected to the power unit 320 and is used to transmit gas to the power unit 320. The first outlet 341 is connected to the nozzle 310 and is used to transmit gas to the nozzle 310. The second outlet 342 is connected to the power unit 320 and is used to transmit gas to the power unit 320. The connection between the branch pipe 345 and the main pipe 344 is located between the inlet 343 and the first outlet 341. The gas from the gas source first enters the main pipe 344 through the inlet 343, and then part of it continues to be transmitted along the main pipe to the nozzle 310, while the other part enters the branch pipe 345 and is then transmitted to the power unit 320 through the branch pipe 345.

[0032] When the transmission pipeline 340 includes a main pipe 344 and a branch pipe 345 connected to the main pipe 344, in some embodiments of this utility model, the cross-sectional area of ​​the branch pipe 345 is smaller than the cross-sectional area of ​​the main pipe 344. That is, most of the gas is used for cleaning the mirror 201, and a small portion of the gas is used to drive the power device 320. This reduces the pressure loss caused by the branch pipe 345 to the main pipe 344, ensuring the cleaning effect of the nozzle 310. For example, the ratio of the cross-sectional area of ​​the branch pipe 345 to the cross-sectional area of ​​the main pipe 344 is less than or equal to 1:20.

[0033] In the aforementioned embodiments, the main pipe 344 and the branch pipe 345 are connected as a single structure. In other embodiments, the transmission pipeline 340 may also include a first pipeline and a second pipeline that are independently set. One end of the first pipeline and the second pipeline is provided with an inlet. The other end of the first pipeline is provided with a first outlet 341, and the other end of the second pipeline is provided with a second outlet 342. The inlets of the first pipeline and the second pipeline may be connected to a gas source respectively, or they may be connected to the same pipe joint first, and then the pipe joint is connected to the gas source.

[0034] Based on the first embodiment, in some embodiments of the present invention, the nozzle 310 is configured to move relative to the mirror 201 to adjust the angle α between the spray direction of the nozzle 310 spraying the cleaning medium and the mirror 201, so that the nozzle 310 sprays the cleaning medium onto different areas of the mirror 201. Specifically, refer to... Figure 2The direction of the cleaning medium sprayed by the nozzle 310 is illustrated by dashed lines in the figure. In some scenarios, the nozzle 310 has a spray nozzle for spraying the cleaning medium, and the spray direction of the nozzle 310 can be understood as the direction of the central axis of the spray nozzle. In other scenarios, when the nozzle 310 is configured as a cylindrical structure and the spray nozzle is located at the end of the nozzle, the spray direction of the cleaning medium sprayed by the nozzle 310 can be further understood as the axial direction of the entire nozzle. Figure 2 As shown in the example, when the nozzle 310 is located on the upper side of the mirror 201, as the nozzle 310 moves, the angle α between the spray direction and the mirror 201 gradually decreases, and the intersection of the dotted line representing the spray direction and the mirror 201 moves downward, which means that the cleaning position of the nozzle 310 on the mirror 201 has changed.

[0035] Based on the above, this embodiment adjusts the angle between the spray direction and the mirror surface 201 by moving the nozzle 310, so that the nozzle 310 can spray cleaning medium to different areas of the mirror surface 201, thereby expanding the cleaning range of the nozzle 310.

[0036] Furthermore, the nozzle 310 is configured to oscillate relative to the mirror 201 around its pivot axis L to adjust the angle between the nozzle 310's spray direction of the cleaning medium and the mirror 201. This oscillation means the nozzle 310 can rotate back and forth in two opposite directions, allowing it to cyclically clean different parts of the mirror 201, thereby further improving the cleaning effect. It should be noted that the oscillation angle of the nozzle 310 can be set as needed. For example, if the nozzle 310 is positioned on one edge of the mirror 201, a suitable angle can be set so that the nozzle 310 can spray the cleaning medium to the opposite edge of the mirror 201, thus expanding the cleaning range.

[0037] When the nozzle 310 can swing relative to the mirror 201, in some embodiments of the present invention, the swing axis L of the nozzle 310 is parallel to the length direction of the mirror 201, and the nozzle 310 is configured to swing relative to the mirror 201 about the swing axis L, so that the nozzle 310 sprays cleaning medium onto different areas of the mirror 201 distributed along its own width direction. (Refer to...) Figure 3 The pivot axis L is indicated by a dashed line in the diagram, and different areas on mirror 201 are indicated by dashed boxes. These different areas are distributed along the width of mirror 201 (i.e., along the vertical direction in the diagram). (Refer to...) Figure 2 To understand this, when the nozzle 310 is located above the mirror 201, as the angle α gradually decreases, the cleaning area of ​​the nozzle 310 on the mirror 201 will also move along the width direction, for example, downwards, thereby increasing the cleaning range.

[0038] In some other embodiments of the present invention, when the nozzle 310 is able to swing relative to the mirror 201, the swing axis L of the nozzle 310 is parallel to the width direction of the mirror 201. The nozzle 310 is configured to swing relative to the mirror 201 about the swing axis L, so that the nozzle 310 sprays cleaning medium onto different areas of the mirror 201 distributed along its own length direction. (Refer to...) Figure 4 The pivot axis L is indicated by a dashed line in the diagram, and different areas on mirror 201 are indicated by dashed boxes. These different areas are distributed along the length of mirror 201 (i.e., along the left-right direction in the diagram). (Refer to...) Figure 2 To understand this, when the nozzle 310 is located to the left of the mirror 201, as the angle α gradually decreases, the cleaning area of ​​the nozzle 310 on the mirror 201 will also move along the length direction, for example, to the right, thereby increasing the cleaning range.

[0039] When the swing axis L of the nozzle 310 is parallel to the length direction of the mirror 201, in some embodiments of this utility model, the cleaning component 300 includes multiple nozzles 310, which are spaced apart along the length direction. In this way, the mirror 201 can be divided into different areas distributed along the length direction and corresponding to each nozzle 310. As mentioned above, the swing of the nozzle 310 can clean the corresponding area along the width direction. Combined with the cleaning effect of all nozzles 310, the mirror 201 can be thoroughly cleaned.

[0040] When the swing axis L of the nozzle 310 is parallel to the width direction of the mirror 201, in some embodiments of the present invention, the cleaning component 300 includes a plurality of nozzles 310, which are spaced apart along the width direction. In this way, the mirror 201 can be divided into different areas distributed along the width direction and corresponding to each nozzle 310. As mentioned above, the swing of the nozzle 310 can clean the corresponding area along the length direction. Combined with the cleaning effect of all nozzles 310, the mirror 201 can be thoroughly cleaned.

[0041] It should be noted that the number of nozzles 310 can be determined based on the spray width of the nozzles 310. When the spray width is wider, the number of nozzles 310 is relatively smaller, and when the spray width is narrower, the number of nozzles 310 is relatively larger.

[0042] When the nozzle 310 can swing relative to the mirror 201, refer to other embodiments of the present invention. Figure 5 , Figure 6The cleaning assembly 300 also includes a power unit 320 and a transmission mechanism 330. The power unit 320 includes a movable power shaft 321. The transmission mechanism is connected to the power shaft 321 and the nozzle 310 respectively. As the power unit 320 operates, the power shaft 321 moves actively, thereby driving the nozzle 310 to swing relative to the mirror surface 201. The transmission mechanism 330 is used to realize the power transmission between the power shaft 321 and the nozzle 310, and to convert the specific movement of the power shaft 321 into the swing of the nozzle 310. For example, it converts the rotation of the power shaft 321 into the swing of the nozzle 310, which will be described in detail below.

[0043] In this embodiment, the power shaft 321 of the power unit 320 is configured to rotate in one direction. For example, the power unit 320 is configured as a rotary cylinder, motor, etc. To convert the unidirectional rotation of the power shaft 321 into the oscillation of the nozzle 310, refer to... Figure 5 , Figure 6 The transmission mechanism 330 includes a ratchet 331 and a pawl 332. The ratchet 331 includes multiple ratchet teeth and is fixedly connected to the power shaft 321, enabling the ratchet 331 to rotate synchronously with the power shaft 321. The pawl 332 is rotatably connected to the housing 100. One end of the pawl 332 abuts against the ratchet teeth of the ratchet 331, and the other end is fixedly connected to the nozzle 310. For example, the left end of the pawl 332 abuts against the ratchet teeth of the ratchet 331, and the right end is fixedly connected to the nozzle 310. A pivot or pivot hole is provided between the two ends of the pawl 332, and the pawl 332 is rotatably connected to the housing 100 through the pivot or pivot hole. Thus, as the ratchet 331 rotates in one direction, the pawl 332 is first driven by the ratchet teeth, thereby causing the nozzle 310 to rotate in one direction. As the ratchet 331 continues to rotate, the pawl 332 disengages from the ratchet teeth, and the pawl 332 and the nozzle 310 rotate in the opposite direction to reset. Repeating the above process can realize the reciprocating oscillation of the nozzle 310.

[0044] In some embodiments, the cleaning assembly 300 further includes an elastic element 333. When the pawl 332 is driven to rotate by the ratchet teeth of the ratchet 331, the elastic element 333 can undergo compression or stretching deformation, so that the pawl 332 and the ratchet teeth remain in close contact. When the pawl 332 disengages from the ratchet teeth, the elastic element 333 can drive the pawl 332 to rotate in the opposite direction to reset, so that the pawl 332 can smoothly engage with the next ratchet tooth. For example, the elastic element 333 can be a tension spring, with one end connected to the pawl 332 and the other end connected to the housing 100. The elastic element 333 can also be a torsion spring, which is sleeved on the shaft used to realize the rotation of the pawl 332.

[0045] It should be noted that in some other specific embodiments, the cleaning component 300 may not have the elastic element 333, and the pawl 332 may be reset and rotated under its own gravity.

[0046] As another way to convert the unidirectional rotation of the power shaft 321 into the oscillation of the nozzle 310, refer to Figure 7 The transmission mechanism 330 includes a rotating wheel 334 and a connecting rod 335. The rotating wheel 334 is fixedly connected to the power shaft 321, enabling the rotating wheel 334 to rotate synchronously with the power shaft 321. The nozzle 310 is rotatably connected to the housing 100. For example, the end of the nozzle 310 away from the spray port is provided with a rotating shaft or a rotating shaft hole, through which the nozzle 310 is rotatably connected to the housing 100. The two ends of the connecting rod 335 are rotatably connected to the rotating wheel 334 and the nozzle 310, respectively, and the connection position between the connecting rod 335 and the rotating wheel 334 is offset from the connection position between the rotating wheel 334 and the power shaft 321. For example, when the center of the rotating wheel 334 is fixedly connected to the power shaft 321, the connection position between the connecting rod 335 and the rotating wheel 334 is offset from the center of the rotating wheel 334. Thus, as the rotating wheel 334 rotates, the end of the connecting rod 335 connected to the rotating wheel 334 will move along a circular trajectory, causing the connecting rod 335 to be displaced in the horizontal direction. For example, if we set... Figure 7 The rotating wheel 334 rotates clockwise. When the connection position between the connecting rod 335 and the rotating wheel 334 is located in the upper half of the rotating wheel 334, the connecting rod 335 will drive the nozzle 310 to rotate to the right as the rotating wheel 334 rotates. When the connection position between the connecting rod 335 and the rotating wheel 334 is located in the lower half of the rotating wheel 334, the connecting rod 335 will drive the nozzle 310 to rotate to the left as the rotating wheel 334 continues to rotate, thereby realizing the reciprocating swing of the nozzle 310.

[0047] By setting the transmission mechanism 330 in the above embodiment, the power shaft 321 of the power unit 320 only needs to rotate in one direction to drive the nozzle 310 to swing back and forth, which simplifies the control of the power unit 320.

[0048] The foregoing embodiments describe a scheme in which the nozzle 310 is driven to swing by a power unit 320 having a rotatable power shaft 321. In some other embodiments, the power shaft 321 can also extend and retract in a straight line to drive the nozzle 310 to swing. For example, the power unit 320 is configured as a telescopic cylinder or an electric cylinder.

[0049] In order to convert the extension and retraction of the power shaft 321 into the oscillation of the nozzle 310, refer to Figure 8 The main body of the power unit 320 (e.g., the cylinder block of a cylinder) is rotatably connected to the housing 100, and the power shaft 321 is rotatably connected to the nozzle 310, which in turn is rotatably connected to the housing 100. Thus, as the power shaft 321 extends or retracts, the power unit 320 rotates relative to the housing 100, and the nozzle 310 swings synchronously. For example, when the power shaft 321 extends or retracts... Figure 8As the length shown continues to extend, the nozzle 310 will rotate to the right, when the drive shaft 321 is at... Figure 8 When the length shown shrinks, the nozzle 310 will rotate to the left.

[0050] Based on the first embodiment, in some embodiments of this utility model, reference is made to Figure 9 The housing 100 has a flange portion 110 that surrounds and protrudes from the mirror surface 201. The inner side of the flange portion 110 has an opening 111, and the nozzle 310 is disposed at the opening 111. This reduces the obstruction of the mirror surface 201 by the nozzle 310, preventing it from affecting the driver's observation through the mirror surface 201. For example, the flange portion 110 has a cavity inside, and the opening 111 communicates with this cavity. The nozzle 310 can be completely housed within this cavity, and the spray nozzle 310's nozzle orifice faces the opening 111, allowing the nozzle 310 to spray cleaning medium outwards through the opening 111. Alternatively, at least a portion of the nozzle 310 extends from the opening 111, with the spray nozzle disposed at the extended portion of the nozzle 310.

[0051] A second aspect of this utility model also proposes a vehicle, which includes a body and the rearview mirror 10 described in the foregoing embodiments. The vehicle can be a private car, such as a sedan, SUV, MPV, or pickup truck. It can also be a commercial vehicle, such as a van, bus, small truck, or large trailer.
