Description

Technical field

[0001] The present disclosure relates to a vehicle cleaning device and in particular a cleaning device which is configured to clean a cover glass covering a sensor section of a vehicle and to clean and remove foreign substances (e.g. contaminants which cause a deterioration of the sensor's performance) which adhere to the exposed outer surface of the cover glass. background

[0002] An autonomous vehicle may be configured to detect the vehicle's external environment and the driver's condition without the driver being involved in operating the vehicle, to use a detection / detection algorithm to detect and determine the surrounding environment, and to control the vehicle based on information obtained through the detection / detection algorithm without the driver's involvement in order to achieve a vehicle goal.

[0003] An autonomous vehicle can, for example, use multiple sensors and a global positioning system (GPS) to detect objects in its surroundings in both forward and backward directions, as well as in left and right directions. Sensors used in autonomous vehicles include, for example, a camera, a radar sensor (radar = "Radio Detection and Ranging"), and a LiDAR sensor (Lidar = "Light Detection and Ranging"). Since each of these sensors has different characteristics, advantages, and disadvantages, autonomous driving can be achieved by integrating / combining numerous sensor systems within the autonomous vehicle.

[0004] In some cases, an autonomous vehicle may have numerous sensors, such as a camera, a LiDAR sensor, and a radar sensor, integrated within it (e.g., combined into a single unit). The camera sensor, for example, might be mounted on the roof of the vehicle to detect the vehicle's surroundings. In some instances, the sensor's external lens, mounted on the vehicle's exterior, can become contaminated by foreign matter such as dust, dirt, and asphalt, as well as by insect carcasses, bird droppings, rain, and snowfall caused by natural phenomena. If the lens is contaminated, the sensor may detect inaccurate information or malfunction.If the sensor does not work normally or is unable to accurately detect the external situation, serious vehicle accidents can occur due to a malfunction of the sensor.

[0022] In some embodiments, which relate to the Fig. Referring to 1 to 6, a vehicle sensor cleaning device 10 can be connected to a sensor section 20 of a vehicle and arranged in a housing 400 to be described later.

[0023] In some embodiments, the sensor section 20 includes a sensor 21, such as a radar sensor, a camera sensor, a LiDAR sensor, or the like, which is integrally installed therein (e.g., combined as a single unit). A plurality of sensor systems can be used in the sensor section to detect the surrounding environment of a vehicle. Furthermore, a camera sensor can be installed on the roof of an autonomous vehicle to detect the vehicle's forward state. Additionally, the sensor 21 can be configured to detect the vehicle's forward state, and any sensor capable of detecting the vehicle's forward state can be used for this purpose.

[0024] The vehicle sensor cleaning device 10 comprises a drive unit (e.g., drive section) 100 with a rotary output mechanism, a movement unit (e.g., movement section) 200, which is moved by the drive unit 100, a cover glass 300, which is connected to the housing 400 and is configured to transparently seal the front of the sensor 21, the housing 400 in which the drive unit 100 and the movement unit 200 are housed, a nozzle 500, which is configured to spray washing fluid (or cleaning fluid), and a cooling fan 600, which is configured to circulate (e.g., recirculate) and cool the internal air of the housing 400. The washing fluid can, for example, contain water and cleaning agents.

[0025] In some examples, the drive part 100 of the vehicle sensor cleaning device 10 has a motor (e.g. an electric motor) 110 and a motor shaft 120 and has a rotary output mechanism.

[0026] The motor 110 of the drive unit 100 is located inside the housing 400, transmits power to the motor shaft 120, regulates its predetermined rotational speed, and is operated to perform forward or reverse rotation. Specifically, the motor 110 is controlled by a control unit to execute a forward or reverse rotation. The motor 110 can be equipped with a programmable microcontroller (MCU) and an encoder system (e.g., a coordinate converter system) suitable for controlling and regulating the angle of the forward and reverse rotations. Furthermore, the motor 110 can communicate with a vehicle via LIN or CAN. The motor 110 can also be a brushless DC motor (BLDC).

[0027] In some examples, the motor shaft 120 of the drive unit 100 can be connected to the motor 110. In some examples, the motor shaft is connected to a worm drive (e.g., a worm shaft) and a worm wheel, which are capable of converting the driving force of the motor 110 into a rotational force. Furthermore, the motor shaft is set in rotation by the worm drive (e.g., the worm shaft) and the worm wheel and serves to rotate the moving part 200 described later.

[0028] In some embodiments, the moving part 200 of the vehicle sensor cleaning device 10 has an arm head rod 210, a holder (also e.g. a bracket) 220, a blade 230 and an elastic element 240.

[0029] For example, the arm end rod 210 of the moving part 200 is designed to be straight. One end of the arm end rod 210 is connected to the motor shaft 120 via a fastening nut, and the other end is pivotally connected to the holder 220, which will be described later. The arm end rod 210 is driven by the rotation of the motor shaft 120, enabling it to rotate forward and backward. Furthermore, the position of the arm end rod 210 is regulated by a guide (not shown), and the arm end rod serves to transmit the rotational force to the holder 220. In addition, the arm end rod 210 can be configured to include at least one horizontal element 211, which is arranged horizontally to the ceiling (e.g., the roof panel / headliner) of a vehicle and parallel to the arm end rod 210 in one direction.The horizontal element 211 can be provided for connection with the elastic element 240 and can be arranged at the other end of the arm head rod 210, which is pivotally connected to the holder 220. Furthermore, the horizontal element 211 is designed to support the elasticity (e.g., spring force) of the elastic element 240 and to press the leaf 230 against the cover glass 300. The horizontal element can be arranged close to (e.g., adjacent to) the holder 220.

[0030] In particular, with reference to Fig. 5, the horizontal element 211 is provided with the elastic element 240. Here, the elasticity (e.g. spring force) of the elastic element 240 is used to pull the arm head rod 210 towards the drive part 100, thereby bringing the blade 230 into close contact with the cover glass 300.

[0031] Furthermore, with reference to Fig. 7, the moving part 200 can have a compression spring bracket (e.g. compression spring holder) 211', depending on the type of elastic element 240 which is attached to the arm head rod 210.

[0032] The compression spring bracket 211' of the arm head 210 is located at the other end of the arm head 210 and is positioned on the upper surface of the arm head 210. The compression spring bracket is designed to support the elasticity (e.g., spring force) of the elastic element 240 by allowing the elastic element 240 to be attached to it. In some examples, a compression spring is connected to the compression spring bracket 211' so that the holder 220 is pulled and / or pushed towards the cover glass 300.

[0033] Depending on the design, either the horizontal element 211 or the compression spring bracket 211' can be attached to the arm head rod 210. In this case, any component can be used as long as it is possible to attach the elastic element 240, which is designed to pull and / or push the leaf 230 towards the cover glass 300, to the component.

[0034] In some embodiments, the holder 220 of the moving part 200 is vertically pivotally connected to the arm head rod 210 and is rotated about the joint. Furthermore, the holder 220 transmits the rotational force of the arm head rod 210 to the blade 230 and converts the elasticity of the elastic element 240 into a force that presses the blade 230. Additionally, a position where the holder 220 and the arm head rod 210 are pivotally connected can be on the same line as a position where the blade 230 and the holder 220 are pivotally connected. Depending on the embodiment, the position where the holder 220 and the blade 230 are pivotally connected can be located a predetermined distance along the vertical line behind the position where the holder 220 and the arm head rod 210 are pivotally connected.

[0035] In particular, the holder 220 of the moving part 200 performs a force conversion to press the blade 230 against the cover glass 300 via the elastic element 240. The holder 220 is moved along the cover glass 300 by the drive element 100, performing a back-and-forth motion in the left and right directions. Furthermore, the holder 220 can clean any foreign substance adhering to the cover glass by combining the direction and force of pressure of the elastic element 240 with the direction and force of rotation of a wiper 232 of the blade 230, taking into account the length of the blade 230 and the pressure of the elastic element 240.

[0036] In some embodiments, the blade 230 of the moving part 200 is connected to the holder 220. The blade 230 is in close contact with the cover glass 300 due to the pressure force of the arm head rod 210 and performs a cleaning function of the cover glass 300 by means of the forward and reverse rotary drives of the arm head rod 210. The blade 230 includes a blade holder 231 and the wiper 232.

[0037] The blade 230 is formed from the blade holder 231, which is connected to the holder 220, and the wiper 232, which cleans the cover glass 300. The blade holder 231 of the blade 230 is stably connected to the holder 220, and the wiper 232 is attached to a surface of the blade holder 231, so that the wiper 232 cleans the cover glass 300 by rotating the arm head rod 210.

[0038] The elastic element 240 of the moving part 200 can be designed as a tension spring or a compression spring, as described above. When using a tension spring, as described in the Fig. 6 and Fig. Figure 7 shows the tension spring attached to the horizontal element 211, and when using a compression spring, the compression spring is attached to the compression spring bracket (also e.g. compression spring hook) 211' to provide a spring force to the holder 220, thereby performing the function of bringing the sheet 230 into close contact with the cover glass 300.

[0039] The cleaning device 10 includes the cover glass 300. The cover glass 300 is designed to protect the front surface of the sensor 21 and to transparently seal the open front of the housing 400. The cover glass 300 can be bonded to the housing 400 and can be made of glass or synthetic resin. Furthermore, the cover glass 300 is either flat or curved and has a structure in which the horizontal length is greater than the vertical length.

[0040] The cleaning device 10 further comprises the housing 400, which is configured to connect the cover glass 300 with its open front surface and to accommodate the drive unit 100 and the motion unit 200 within it. The housing 400 consists of a lower cover that accommodates the drive unit 100, the motion unit 200, and the cooling fan 600, and an upper cover that protects the drive unit 100, the motion unit 200, and the cooling fan 600.

[0041] The cleaning device 10 further comprises the nozzle 500, which sprays cleaning fluid onto the cover glass 300. The nozzle 500 can be connected to the lower cover of the housing and can be aligned with the lower cover at an oblique angle instead of a right angle. Spraying the cleaning fluid onto the cover glass 300 at an oblique angle allows for optimal coverage. This enables efficient control of the amount of fluid sprayed onto the cover glass 300.

[0042] In some embodiments, the cleaning device 10 also includes a cooling fan 600. The cooling fan 600 draws air from inside the housing 400 to the outside and circulates the air to cool the interior of the housing 400.

[0043] In some examples, the moving part 200 of the cleaning device 10 is designed in a cantilever shape, which is fixed to the drive part 100. The moving part 200 has the holder 220, which is connected to its other end, and the blade 230, which is connected to the holder 220, performs a back-and-forth movement in the left and right directions by forward and backward rotation of the holder 220 (e.g., based on the direction of rotation of the motor), thereby moving along the outer surface of the cover glass 300.

[0044] In particular, the moving part 200 performs a back-and-forth movement, moving in the left and right directions by means of a guide (not shown) to clean the cover glass 300. In an area of ​​the cover glass where the sensor 21 is located, the cover glass 300 moves at a constant speed (a first speed), and in an area of ​​the cover glass 300 where the sensor 21 is not located, the cover glass 300 moves (e.g., relative to the first speed) at an increased (e.g., accelerated) or a decreased (e.g., decelerated) speed. The increased and decreased speeds can be referred to as second speeds, which differ from the first speed.For example, while controlling the forward rotation, reverse rotation, angle, and speed of the drive unit 100, the moving unit 200 can move at an increased or decreased speed in the area of ​​the cover glass 300 where the sensor 21 is not located, and at a constant speed in the area of ​​the cover glass 300 where the sensor 21 is located. For example, when the moving unit 200 is driven, it moves to / into an area of ​​the cover glass 300 where the sensor 21 is not located. At this point, the moving unit 200 moves at an increased speed. When the moving unit moves to / into an area of ​​the cover glass 300 where the sensor 21 is located, it moves at a constant speed.When the moving part moves back to / into the area of ​​the cover glass 300 in which the sensor 21 is not located, then the moving part 200 moves at a reduced speed.

[0045] When the moving part 200 moves in the opposite direction, it moves at the same speed (e.g., the same speed profile) as described above. This means that the moving part 200 moves along the surface of the cover glass 300 in the sequence of increased speed, constant speed, and decreased speed. In this way, the moving part 200 can remove contaminants from the surface of the cover glass 300.

[0046] As described above, in the area of ​​the cover glass where the sensor 21 is not located, reversal noise and the like can be reduced to a maximum, and the moving part 200 can move at a low speed, while in the area of ​​the cover glass where the sensor 21 is located, the moving part 200 can move at maximum speed.

[0047] Fig. Figure 8 is a drawing showing an example of a moving part of a vehicle sensor cleaning device, and Fig. Drawings 9A to 9F each show an example of a vehicle sensor cleaning device.

[0048] With reference to Fig. Section 8 describes an example of a vehicle sensor cleaning device. For example, an arm head 210' of the moving part 200 can be configured to branch into at least two arm head rods. As in Fig. As shown in Figure 8, each of the arm end rods 210' can be configured to be equipped with an elastic element 240' to pull a (e.g., associated) blade towards a drive section. For example, in the moving section, one or more holders 220' can each be pivotally connected to one or more (e.g., associated) arm end rods 210', and one or more blades 230' can each be connected to one or more (e.g., associated) holders 220'. Additionally, at least one cover glass 300 is provided, and the respective angles of the arm end rods 210' can be set differently. In this way, the arm end rods can be used to clean the cover glass 300' located near (e.g., adjacent to) the sensor.

[0049] In the Fig. For example, in figures 9A to 9F, the angle of the bracket 220', which is pivotally connected to the centrally arranged arm-head rod 210', is bent at a different angle than the other brackets. In other words, the end of the centrally arranged arm-head rod 210' is bent at an obtuse angle (see figure 9A to 9F). Fig. 9C and Fig. 9E). When the holders 220' are rotated around the respective joints, a structure of the holder 220', which is connected to the arm head rod at a different angle, allows the holder 220' located in the middle to move in a straight direction and clean the cover glass 300' (see Fig. 9D and Fig.9E). Accordingly, the cover glass 300, which is located near (e.g., adjacent to) the sensor 21, can be cleaned by the holders 220', which are connected to two respective arm-head rods 210' located on either side of the centrally arranged arm-head rod 210', and at the same time the cover glass 300', which is located at a distance from the cover glass 300, can be cleaned by the holder 220', which is connected to the centrally arranged arm-head rod 210'. The moving part can also move at an increased or decreased speed in an area of ​​the cover glass where the sensor is not located, and can also move at a constant speed in an area of ​​the cover glass where the sensor is not located.

[0050] In some embodiments, a vehicle sensor cleaning device can not only enable intuitive cleaning of the cover glass, but also the rapid removal of contaminants that may not be removed by air (e.g., wind) and a car wash cleaning system.

[0051] In addition, the cover glass is positioned in front of a sensor to effectively protect the expensive sensor.

[0052] Finally, a cooling fan is installed inside the housing to prevent the formation of moisture inside the housing and to cool the sensor, thus enabling the sensor function to be performed effectively.

[0053] As can be seen from the above description, the present disclosure can achieve the following effects through the configuration, combination and usage relationship described in the embodiments.

[0054] The present disclosure can provide a device which is capable of intuitively and effectively cleaning a cover glass which covers a sensor.

[0055] The present disclosure has been described in detail with reference to exemplary embodiments, and the present disclosure can be used in numerous other combinations, modifications, and environments. That is to say, those skilled in the art understand that modifications to these embodiments can be made without departing from the principles and essence of the disclosure, the scope of which is defined in the appended claims and their equivalents. The embodiments describe the best way of implementing the technical idea of ​​the present disclosure, and numerous modifications in specific fields of application and uses of the present disclosure are also possible. Accordingly, the detailed description of the present disclosure is not intended to limit the present disclosure to the disclosed embodiments.Furthermore, the scope of the attached claims should be interpreted in such a way as to also include further embodiments.
