Description

[Technical Field]

[0001] The present invention relates to a sensor cleaning device for cleaning automotive sensors. [Background technology]

[0002] Automotive sensors can enhance the safety and comfort of automobiles and enable autonomous driving. By way of example, automotive sensors can be cameras operating in the visible light spectrum or the infrared spectrum. Furthermore, automotive sensors can be radar sensors, LiDAR sensors, and ultrasonic sensors.

[0003] During vehicle operation, vehicle sensors are exposed to environmental influences such as road dirt kicked up by preceding vehicles, bird droppings, and rain.

[0004] To protect the operational reliability of the automotive sensor, it is important to ensure that the front surface of the automotive sensor through which the optical, infrared, radar or ultrasonic signal passes is kept clean and that this surface is free of dirt. By way of example, the optical signal may be a laser signal or laser beam.

[0005] It is known in the prior art that fluids in the form of water and air are used to clean the front surface of an automobile sensor, whereby the front surface of the automobile sensor is exposed to water and air ejected from a sensor cleaning device.

[0006] Because different automotive sensors come in different sizes and geometries, different sensor cleaning devices must be used for each to achieve acceptable cleaning results. Summary of the Invention [Problem to be solved by the invention]

[0007] One objective underlying the present invention is to provide a sensor cleaning device that can be more easily used to clean different automotive sensors without having to modify the overall structure of the sensor cleaning device. [Means for solving the problem]

[0008] This object of the present invention is solved by a sensor cleaning device exhibiting the features of claim 1. The claims dependent on claim 1 describe different embodiments of the sensor cleaning device.

[0009] More precisely, the object of the present invention is solved by a sensor cleaning device for cleaning automotive sensors, the sensor cleaning device presenting a housing having at least one first housing inlet, at least one second housing inlet, and housing outlet openings for distributing fluids introduced into the housing via the at least one first housing inlet and / or the at least one second housing inlet, the sensor cleaning device further presenting a fluid distribution device for guiding the fluids introduced into the housing via the at least one first housing inlet and the at least one second housing inlet to the housing outlet openings, the fluid distribution device presenting a number of first distribution inlets corresponding to the number of first housing inlets and a number of first distribution outlets corresponding to at least the number of first distribution inlets, and a number of second distribution inlets corresponding to the number of second housing inlets and a number of second distribution outlets corresponding to at least twice the number of second distribution inlets. The fluid distribution device is insertable into the housing, and when the fluid distribution device is inserted into the housing, each first distribution inlet is fluidly connected to one first housing inlet and each second distribution inlet is fluidly connected to one second housing inlet.

[0010] A correspondingly designed sensor cleaning device offers the advantage that it can be used for different automobile sensors having different sizes and different geometries simply by replacing the fluid distribution device. For example, a correspondingly designed sensor cleaning device can be used for an automobile sensor having a relatively small front surface, whereby, for example, a fluid distribution device having only three secondary distribution outlets is inserted into the housing. The same sensor cleaning device can be used for an automobile sensor having a relatively large front surface, whereby, for example, a fluid distribution device having four, five, six, or even more secondary distribution outlets is inserted into the housing. Furthermore, assembly of a correspondingly constructed sensor cleaning device is extremely easy.

[0011] When the sensor cleaning device presents one first housing inlet and one second housing inlet, the sensor cleaning device can be described as follows: a sensor cleaning device for cleaning an automobile sensor, the sensor cleaning device presenting a housing having a first housing inlet, a second housing inlet, and having a housing outlet opening for distributing a fluid introduced into the housing via the first housing inlet and / or the second housing inlet, the sensor cleaning device further presents a fluid distribution device for guiding the fluid introduced into the housing via the first housing inlet and the second housing inlet to the housing outlet opening, the fluid distribution device presenting a first distribution inlet and at least one first distribution outlet, and a second distribution inlet and at least two second distribution outlets, The fluid distribution device is insertable into the housing, and when the fluid distribution device is inserted into the housing, the first distribution inlet is in fluid communication with the first housing inlet and the second distribution inlet is in fluid communication with the second housing inlet.

[0012] When the sensor cleaning device presents two first housing inlets and two second housing inlets, the sensor cleaning device can be described as follows: the housing of the sensor cleaning device presents two first housing inlets and two second housing inlets, and fluid introduced into the housing via the first housing inlet and / or the second housing inlet can be distributed through the housing outlet opening, and the fluid distribution device presents two first distribution inlets and at least two first distribution outlets, and two second distribution inlets and at least two second distribution outlets, and when the fluid distribution device is inserted into the housing, each first distribution inlet is fluidly connected to one first housing inlet and each second distribution inlet is fluidly connected to one second housing inlet.

[0013] The automotive sensors cleaned by the sensor cleaning device may be, for example, Lidar sensors, radar sensors, optical sensors, lenses of optical sensors, ultrasonic sensors, etc.

[0014] By way of example, the first housing inlet can be used as a liquid inlet for admitting liquid (e.g., water or cleaning solution) into the housing, and therefore the first housing inlet can also be referred to as a liquid inlet and a liquid housing inlet, respectively.

[0015] Further, by way of example, the second housing inlet can be used as a gas inlet and an air inlet, respectively, for admitting a gas (e.g., air or another gas) into the housing. Thus, the second housing inlet can also be referred to as a gas inlet, an air inlet, a gas housing inlet, and an air housing inlet, respectively. Gas is also a fluid.

[0016] By way of example, the first housing inlet and the second housing inlet can each be designed as an inlet nozzle.

[0017] By way of example, the sensor cleaning device presents exactly one outlet opening.

[0018] The fluid that can be dispensed through the housing outlet opening is a fluid that is introduced into the housing via the first housing inlet and the second housing inlet.

[0019] The fluid dispensing device may also be referred to as a chip.

[0020] By way of example, the fluid distribution device is replaceably inserted into the housing.

[0021] The first dispense inlet is in fluid communication with the first dispense outlet opening.

[0022] The second distribution inlet is in fluid communication with all of the second distribution outlets.

[0023] When the distribution device is inserted into the housing, the first distribution inlet is in fluid communication with the first housing inlet and the second distribution inlet is in fluid communication with the second housing inlet, so that fluid introduced through the first housing inlet is distributed through the housing outlet opening via the first distribution outlet, and fluid introduced through the second housing inlet is distributed through the housing outlet opening via at least two second distribution outlets.

[0024] By way of example, the fluid distribution device presents two first distribution outlets.

[0025] By way of example, the fluid distribution device presents three or more first distribution outlets.

[0026] By way of example, the fluid distribution device presents three secondary distribution outlets.

[0027] By way of example, the fluid distribution device presents four secondary distribution outlets.

[0028] By way of example, the fluid distribution device presents five secondary distribution outlets.

[0029] By way of example, the fluid distribution device presents six secondary distribution outlets.

[0030] By way of example, the fluid distribution device presents seven or more secondary distribution outlets.

[0031] By way of example, the fluid distribution device may be constructed at least in part from plastic, for example, the fluid distribution device may be constructed as an injection molded component.

[0032] In the installed state, i.e., when the sensor cleaning device is installed in a vehicle, for example, the first distribution outlet and the second distribution outlet may be arranged at the same horizontal level.Furthermore, in the installed state, i.e., when the sensor cleaning device is installed in a vehicle, for example, the first distribution outlet and the second distribution outlet may be arranged at different horizontal levels.

[0033] Preferably, each first distribution outlet is fluidly connected to a first distribution inlet via a first outlet channel.

[0034] A correspondingly designed sensor cleaning device exhibits a very simple structure and is therefore very easy to manufacture.Preferably, the first outlet channel is realized by a first recess in the fluid distribution device.

[0035] More preferably, the cross section of at least one of the first outlet channels increases in the direction from the first distribution inlet to the first distribution outlet.

[0036] A correspondingly designed sensor cleaning device has the advantage that the liquid dispensed through the first dispensing outlet also evaporates, thus ensuring that the larger vehicle sensor and the front surface of the vehicle sensor, respectively, can be cleaned by the fluid dispensed from the first dispensing outlet.

[0037] Preferably, the fluid distribution device presents at least one distribution chamber terminated by a second distribution inlet, and at least two second distribution outlets each fluidly connected with the distribution chamber via a second outlet channel.

[0038] A correspondingly designed sensor cleaning device offers the advantage that the at least two second outlet channels are equally supplied with fluid. By way of example, this fluid is air or another gas. Furthermore, the correspondingly designed fluid distribution device is simple in design and can therefore be easily manufactured.

[0039] A correspondingly designed sensor cleaning device exhibits a very simple structure and is therefore very easy to manufacture.Preferably, the second outlet channel is realized by a second recess in the fluid distribution device.

[0040] The fluid distribution device exhibits a number of second outlet channels equal to the number of second distribution outlets.

[0041] By way of example, all of the second outlet channels may have a rectangular cross-sectional shape. Further by way of example, all of the second outlet channels may have a circular or elliptical cross-sectional shape. Further by way of example, different second outlet channels may have different cross-sectional shapes.

[0042] Preferably, the total cross-sectional area of ​​all the second outlet channels is less than 0.5 mm 2 ~3mm 2 is in the range.

[0043] Preferably, the total cross-sectional area of ​​all the second outlet channels is less than 0.7 mm 2 ~2mm 2 Preferably, the total cross-sectional area of ​​all the second outlet channels is in the range of 0.8 mm 2 ~1.5mm 2 Preferably, the total cross-sectional area of ​​all the second outlet channels is in the range of 0.9 mm 2 ~1.1mm 2 is in the range.

[0044] Surprisingly, it has been found by the inventors of the present invention that when the sum of the cross-sectional areas of all the second outlet channels is in the range specified above, a very good compromise is achieved between good directionality of the fluid / air distributed through the second distribution outlets (high directionality is desired) and flow rate through all the second distribution outlets (high flow rate is desired).

[0045] Preferably, the at least two second outlet channels each exhibit a length (L) in the range of 2 mm to 6 mm.

[0046] Preferably, the at least two second outlet channels each present a length in the range of 3 mm to 5 mm. Preferably, the at least two second outlet channels each present a length in the range of 3.5 mm to 4.5 mm.

[0047] Surprisingly, it has been found by the inventors of the present invention that when the length of the second outlet channel is in the range specified above, a very good compromise is achieved between good directionality of the fluid / air distributed through the second distribution outlets (high directionality is desired) and flow rate through all the second distribution outlets (high flow rate is desired).

[0048] Preferably, the cross sections of the at least two second outlet channels differ from each other.

[0049] A correspondingly designed sensor cleaning device presents the advantage that the application of the fluids emitted from the housing opening and the second dispensing outlet, respectively, to the optical sensor can be designed as needed.

[0050] For example, if the cross-section of the second outlet channel opening into the second outlet opening facing the center of the vehicle sensor is larger or smaller than the cross-section of the second outlet channel opening into the second outlet opening facing the boundary area of ​​the vehicle sensor, the center of the vehicle sensor will be exposed to a different amount of fluid than the boundary of the vehicle sensor.

[0051] Preferably, the at least one first outlet channel and the at least one second outlet channel are directed towards each other.

[0052] The first outlet channel and the second outlet channel are oriented toward one another so that each longitudinal axis of each second outlet channel is oriented toward the longitudinal axis of the first outlet channel.

[0053] A correspondingly designed sensor cleaning device offers the advantage that excellent cleaning results are achieved.

[0054] Preferably, the fluid distribution device is insertable into the housing through the housing outlet opening.

[0055] A correspondingly designed sensor cleaning device has a very simple design, since the housing outlet opening, which must be provided in any case, is used to insert the fluid distribution device into the housing of the sensor cleaning device.

[0056] Preferably, the fluid dispensing device is insertable into the housing through the mounting opening.

[0057] For example, the mounting opening is located opposite the housing outlet opening. It is also possible for the mounting opening to be located on a side of the housing.

[0058] Preferably, the fluid dispensing device exhibits at least one locking member for properly connecting the fluid dispensing device with the housing.

[0059] A correspondingly designed sensor cleaning device presents the advantage that the mounting of the fluid distribution device in the housing is very easy and, moreover, very reliable.

[0060] Preferably, the sensor cleaning device comprises a first housing A heating device for heating the inlet and / or the fluid distribution device is provided.

[0061] A correspondingly designed sensor cleaning device offers the advantage that the sensor cleaning device functions reliably even in low temperature environments below 0°C.

[0062] Preferably, the fluid distribution device is constructed at least in part from metal.

[0063] The correspondingly designed sensor cleaning device is very durable and also exhibits high thermal conductivity, thus offering the advantage that the sensor cleaning device can function reliably even in low temperature environments below 0°C, especially when the sensor cleaning device is a heating device.

[0064] Preferably, the sensor cleaning device exhibits two or more fluid distribution devices housed within the housing of the sensor cleaning device.

[0065] A correspondingly designed sensor cleaning device presents the advantage that even very large vehicle sensors can be reliably cleaned by the sensor cleaning device.

[0066] Further advantages, details and features of the present invention are explained in the following examples. [Brief explanation of the drawings]
