Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a cleaning device for a vehicle-mounted camera. Background Art

[0002] As a modern means of transportation, cars have become an inseparable part of people's lives today. During the driving process, as users' requirements for vehicle functions become more and more stringent and humanized, the installation rate of on-board cameras in vehicles is getting higher and higher. On-board cameras can facilitate people's driving, such as transmitting surrounding environment images in real time, assisting drivers to make the best driving control actions, and automatically identifying various risky driving scenarios. Give drivers risk warning prompts to reduce the probability of traffic accidents, and be able to record the vehicle's driving for easy viewing and evidence.

[0003] According to the classification of vehicle-mounted cameras according to their layout positions, they can be divided into in-cabin cameras and out-cabin cameras. The cleanliness of in-cabin cameras is related to the cabin environment, which is usually not easy to get dirty, and it is very convenient to manually clean such cameras. The cleanliness of out-cabin cameras is related to the external environment of the car, and cleaning is more difficult, and the camera cannot be cleaned manually while the car is driving. When the car encounters bad weather such as rain, snow, and fog while driving, it usually causes dirt on the surface of the out-cabin camera lens, and even freezing and frost, which greatly affects the normal operation of the camera. If the dirt on the camera surface cannot be cleaned in time while the car is driving, it will have a great impact on the driver's driving safety.

[0004] Existing outboard cameras usually coat the outermost lens surface to achieve a hydrophobic effect, which can ensure that the lens's field of view on rainy days is not affected by rain to a certain extent. However, for the complex and changeable external environment of the car, the role of the hydrophobic film is relatively limited, and the actual service life is relatively short. There is also a device with a blowing function, which cooperates with the guide channel to spray a curtain-like airflow to achieve the cleaning effect of the dust on the lens surface. This device only has a strong cleaning effect on the floating dust on the lens surface, but cannot clean water stains, frost, or even stains that stick to the lens after drying. There is also a cleaning tool similar to the wiper on the front windshield of a car installed on the vehicle, which is driven by a crank-connecting rod mechanism to stick to the lens surface and effectively clean various dirt on the lens surface. However, this cleaning device usually has problems such as large size, many parts, and complex structure. Utility Model Content

[0045] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0046] Combine the following Figures 1 to 6 , describing an embodiment of the utility model.

[0047] According to the embodiments of the present utility model, Figure 1 and Figure 2 As shown, a cleaning device for a vehicle-mounted camera is provided, comprising a limit assembly 1, a cleaning strip 2 and a pump assembly 3. The limit assembly 1 is suitable for being installed on a vehicle body. A mounting hole is provided on the limit assembly 1, and the mounting hole is suitable for installing a camera 7. A limit groove 101 is provided on the limit assembly 1, and the limit groove 101 is located at the periphery of the mounting hole. The cleaning strip 2 is movably installed in the limit groove 101. The cleaning strip 2 has a storage position 1011 located in the limit groove 101 and a cleaning position 1012 located on one side of the camera 7. A accommodating cavity 201 is provided inside the cleaning strip 2, and one end of the cleaning strip 2 is closed and the other end is provided with an opening. The pump assembly 3 is suitable for being installed on a vehicle body, and the pump assembly 3 is connected to the opening for inputting or outputting a medium into the opening, so as to drive the cleaning strip 2 to reciprocate between the storage position 1011 and the cleaning position 1012.

[0048] Specifically, in this embodiment, there is no limitation on the installation position of the cleaning device for the vehicle camera, and the cleaning device may be installed at the front, rear or side of the vehicle body to clean the camera 7 at the front, rear or side of the vehicle.

[0049] In this embodiment, a mounting hole is provided in the middle position of the limit assembly 1. When the limit assembly 1 is installed on the vehicle body, the lens part of the camera 7 is just installed in the mounting hole, and the lens of the camera 7 slightly protrudes from the surface of the limit assembly 1. When the cleaning strip 2 passes through the lens surface of the camera 7, it can always maintain a fit state with the lens surface and will not separate from the lens surface during the swinging process.

[0050] In this embodiment, the limiting groove 101 on the limiting component 1 is in a "concave" shape, and the two sides and the bottom of the limiting groove 101 enclose the camera 7 lens in the limiting groove 101. In some other embodiments, the two sides and the top of the limiting groove 101 can also enclose the camera 7 lens in the limiting groove 101, or one side, the top and the bottom of the limiting groove 101 can enclose the camera 7 lens in the limiting groove 101.

[0051] In this embodiment, Figure 3 and Figure 4 As shown, the cleaning strip 2 is made of a flexible material, such as soft rubber, silicone, etc. The interior of the cleaning strip 2 is a hollow accommodating chamber 201. One end of the cleaning strip 2 is sealed, and the other end is connected to the pump assembly 3. When there is no medium in the accommodating chamber 201 in the cleaning strip 2, the cleaning strip 2 is in a soft curved state and is accommodated in the limiting groove 101. When the pump assembly 3 inputs the medium into the accommodating chamber 201, the pressure in the cleaning strip 2 increases, so that the rigidity of the cleaning strip 2 increases. The high-pressure medium forces the cleaning strip 2 to be in a straight line shape. During the deformation process, the cleaning strip 2 is attached to the lens surface to complete the swinging motion, thereby wiping the lens surface. When the pump assembly 3 withdraws the medium, the pressure in the cleaning strip 2 decreases, and the rigidity of the cleaning strip 2 also decreases, and it returns to the limiting groove 101 in the accommodation position 1011. Since the accommodating chamber 201 in the cleaning strip 2 in this embodiment needs to withstand the pressure of the medium, when selecting the material of the cleaning strip 2, a pressure-resistant material should be selected.

[0052] In this embodiment, the pump assembly 3 can input and extract media such as hydraulic oil, antifreeze liquid or gas into and out of the accommodating cavity 201 in the cleaning strip 2.

[0053] The utility model installs a cleaning scraper 2 in the limiting groove 101 of the limiting component 1. When the camera 7 needs to be cleaned, a medium is input into the opening through the pump component 3. The medium is filled in the accommodating cavity 201 to deform the cleaning scraper 2. During the deformation process, the cleaning scraper 2 passes through the surface of the camera 7 and can scrape and remove the stains on the surface of the camera 7. After cleaning, the medium pump component 3 draws the medium back from the accommodating cavity 201 to restore the cleaning scraper 2 to the limiting groove 101. The utility model has the advantages of simple structure, less space occupied by the vehicle body, good cleaning effect, and easy operation.

[0054] In one embodiment, Figure 5 and Figure 6 As shown, the limiting assembly 1 further includes an elastic member 102, which is installed in the closed section of the limiting groove 101, and abuts against one closed end of the cleaning strip 2. The elastic member 102 has an elastic force that drives the cleaning strip 2 to return to its original position.

[0055] Specifically, in this embodiment, the elastic member 102 is installed in the limiting groove 101 at one end away from the pump assembly 3. Figure 5 As shown, when the cleaning strip 2 is in the storage position 1011, the elastic member 102 is in a slightly compressed state, and the cleaning strip 2 is in a forced bending state. Its curvature and shape are limited by the shape of the positioning groove 101 and the elastic force of the elastic member 102. It is located at the lower end of the lens surface of the camera 7, and is as close to the lens surface of the camera 7 as possible without blocking the imaging of the camera 7, as shown in FIG. Figure 6 As shown, when the pump assembly 3 inputs the medium into the cleaning scraper 2, the stiffness of the cleaning scraper 2 increases, causing the cleaning scraper 2 to change from a bent state to a straightened state. During the straightening process, the end of the cleaning scraper 2 that is in contact with the elastic member 102 is limited by the limiting groove 101 and extends toward the depth of the limiting groove 101, while squeezing the elastic member 102 so that the elastic member 102 is compressed; when the driving member draws the medium back, the stiffness of the cleaning scraper 2 decreases, and it returns to its original position under the deformation of the cleaning scraper 2 itself and the elastic force of the elastic member 102.

[0056] In this embodiment, no specific position limitation is imposed on the elastic member 102. According to actual conditions, the elastic member 102 in this embodiment is a spring. In some other embodiments, the elastic member 102 may also be a spring sheet or the like.

[0057] The utility model installs an elastic member 102 in the limiting groove 101. When the cleaning strip 2 is in the cleaning position 1012, the elastic member 102 is compressed. After cleaning is completed, the elastic force of the elastic member 102 can drive the cleaning strip 2 to return to the limiting groove 101 in its original position. Such a setting has the advantages of simple structure, less space occupied by the vehicle body, and easy operation.

[0058] In one embodiment, Figure 1As shown, the limiting assembly 1 further includes a storage bin 103 , which is suitable for being installed on a vehicle body, wherein a mounting hole is provided on the storage bin 103 , and the limiting groove 101 is provided on the storage bin 103 .

[0059] Specifically, in this embodiment, the storage bin 103 is in a cubic shape, and the mounting hole is arranged in the middle position of the storage bin 103. The limiting groove 101 around the mounting hole is in a boss shape. When the cleaning strip 2 is in the storage position 1011, part of the cleaning strip 2 abuts against the boss-shaped limiting groove 101. The limiting groove 101 for accommodating the sealed end of the cleaning strip 2 is in a hole shape and is arranged inside the storage bin 103. The elastic member 102 is installed in the limiting groove 101 of the hole-shaped closed section.

[0060] In one embodiment, Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, the limiting assembly 1 further includes two limiting blocks 104, which are mounted on the storage bin 103, the camera 7 is located between the two limiting blocks 104, and an opening is provided on the limiting block 104, through which the cleaning strip 2 is passed.

[0061] Specifically, in this embodiment, two limit blocks 104 are arranged at the top of the boss-shaped limit groove 101, and the height of the limit block 104 is higher than the top position of the camera 7. When the cleaning scraper 2 is in the cleaning position 1012, the limit block 104 can make the part of the cleaning scraper 2 between the two limit blocks 104 in a stretched state. The limit block 104 is set higher than the camera 7, and the lens of the camera 7 can be completely wiped during the deformation and stretching process of the cleaning scraper 2, thereby increasing the cleaning range of the cleaning scraper 2 and improving the cleaning effect.

[0062] The utility model provides two limit blocks 104 to guide and limit the cleaning strip 2, so that the cleaning strip 2 can wipe the surface of the camera 7 during movement, thereby removing dirt adhering to the surface of the camera 7.

[0063] In one embodiment, Figure 1 As shown, the pump assembly 3 includes a hydraulic pump or a pneumatic pump 301 suitable for being installed on a vehicle body and a connecting pipe 302 connecting the hydraulic pump or the pneumatic pump 301 and the accommodating chamber 201 .

[0064] Specifically, the hydraulic pump or air pump 301 in this embodiment is used to pressurize hydraulic oil, coolant or gas medium into the cleaning scraper 2, and to withdraw the medium in the cleaning scraper 2. A pressure detection component is provided on the hydraulic pump or air pump 301. When the pressure detection component detects that the pressure in the accommodating chamber 201 reaches a predetermined pressure value, the hydraulic oil injection action is stopped, and the hydraulic pump direction is controlled to withdraw the hydraulic oil.

[0065] The utility model provides a hydraulic pump or a pneumatic pump 301, so that the medium can be input into or extracted from the accommodating chamber 201 of the cleaning scraper 2 through the connecting pipe 302. When the medium is input into the cleaning scraper 2, the pressure inside the cleaning scraper 2 increases, causing the cleaning scraper 2 to deform into a straight state. During the movement, the cleaning scraper 2 passes through the surface of the camera 7 to wipe the dirt adhering to the surface of the camera 7. When the medium is extracted from the cleaning scraper 2, the pressure inside the cleaning scraper 2 decreases, causing it to return to its original state and be stored in the limiting groove 101.

[0066] In one embodiment, Figure 1 As shown, the cleaning device for the vehicle-mounted camera further includes a shell 4 suitable for being installed on a vehicle body, and the limiting component 1 and the pump component 3 are installed in the shell 4 .

[0067] Specifically, in this embodiment, there is no specific limitation on the shape of the shell 4. According to the different installation spaces in different vehicles, the shell 4 adopts a shape that is adapted to the vehicle body. The interior of the shell 4 is a cavity, and the storage bin 103, the hydraulic pump or the pneumatic pump 301 and the connecting pipe 302 are installed inside the shell 4, and the storage bin 103 is provided with a mounting hole on one side that is exposed to the outside of the shell 4.

[0068] In one embodiment, Figure 1 and Figure 2 As shown, the cleaning device for the vehicle-mounted camera further includes a heating component 5 , which is suitable for being installed in the housing 4 , and is connected to the cleaning strip 2 .

[0069] When dirt such as ice and snow adheres to the camera 7 of the vehicle in winter, the utility model can heat the cleaning strip 2 by setting the heating component 5. The heated cleaning strip 2 is used to wipe the camera 7, so that dirt such as ice and snow can be melted and wiped off, thereby improving the cleaning effect. The utility model has the advantages of simple structure and convenient operation.

[0070] In one embodiment, Figure 1 and Figure 4 As shown, the heating assembly 5 includes a heating element 501 disposed in the cleaning strip 2 and a heater 502 suitable for being installed in the housing 4 , and the heater 502 is electrically connected to the heating element 501 .

[0071] Specifically, in this embodiment, the heating element 501 adopts a resistance wire, a thermistor (PTC), an electric heating film, etc., and the heater 502 adopts a power supply device for supplying power to the heating element 501 to increase the temperature. In this embodiment, a temperature detection element is provided in the heater 502, which is connected to the signal of the automobile controller, and can monitor the resistance value of the heating element 501, and control the heating duration and the temperature of the heating element 501 in real time, so as to realize the control of the heating function, prevent the temperature required for cleaning from being insufficient or the overheating protection of the heater 502.

[0072] In this embodiment, the heating element 501 can be an integrated structure with the cleaning strip 2 and the connecting tube 302 , and buried in the body of the cleaning strip 2 and the tube wall of the connecting tube 302 .

[0073] In this embodiment, the cleaning scraper 2 includes a flexible scraper and a pressure-resistant tube body. The pressure-resistant tube body is provided with a receiving cavity 201. The heating element is buried in the heating tube body. The scraper and the pressure-resistant tube are integrally formed.

[0074] The utility model sets a heating element 501 in the cleaning scraper 2 and uses electric energy to heat the heating element 501, so that the temperature of the cleaning scraper 2 rises. When the cleaning scraper 2 wipes the surface of the camera 7, the heated cleaning scraper 2 can melt the ice and snow adhering to the surface of the camera 7 and wipe it clean, avoiding the influence of ice, snow, frost and fog on the camera 7 in winter, thereby ensuring the safety of the vehicle.

[0075] In one embodiment, Figure 1 As shown, the cleaning device for the vehicle-mounted camera also includes a water spray assembly 6 , which is suitable for being installed in the housing 4 . A nozzle 601 is provided on the water spray assembly 6 , and the nozzle 601 faces the camera 7 .

[0076] Specifically, the present embodiment does not impose any specific limitation on the setting position of the nozzle 601. To conform to the actual situation, the nozzle 601 is located above the camera 7 in the present embodiment, and the water outlet direction of the nozzle 601 is toward the camera 7 and is tangent to the lens surface of the camera 7. In some other embodiments, the nozzle 601 may also be set below the camera 7, or at other positions, but the water outlet direction of the nozzle 601 should always be toward the camera 7.

[0077] In this embodiment, the water spray assembly 6 can spray liquids such as detergent, glass water and clean water.

[0078] The utility model provides a water spray assembly 6. When dirt adheres to the camera 7, a proper amount of cleaning agent can be sprayed on the surface of the camera 7 to rinse the surface of the camera 7, and the cleaning scraper 2 can be used to wipe the dirt to remove it, so as to avoid the hard particles in the dirt from wearing the surface of the camera 7 directly by wiping with the cleaning scraper 2.

[0079] In one embodiment, Figure 1 As shown, the water spray assembly 6 includes a second pump body 602 and a water outlet pipe 603. The second pump body 602 is suitable for being installed in the housing 4. One end of the water outlet pipe 603 is connected to the second pump body 602, and the other end is provided with a nozzle 601.

[0080] Specifically, in this embodiment, the second pump body 602 adopts a hydraulic pump. The second pump can be connected to the windshield washer fluid storage tank in the vehicle body to pump the windshield washer fluid in the vehicle body to the nozzle 601. A separate detergent storage tank can also be set up, and the liquid in the detergent storage tank can be pumped to the nozzle 601 through the second pump body 602, and a certain amount of detergent can be sprayed toward the camera 7.

[0081] The utility model provides a second pump to deliver the cleaning agent to the nozzle 601 through the water outlet pipe 603 , so as to facilitate flushing of dirt on the camera 7 , thereby further improving the cleaning effect of the camera 7 .

[0082] In this embodiment, the controller in the vehicle body is connected to the hydraulic pump or air pressure pump 301 , the second pump body 602 and the heater 502 by signal, so as to control the coordinated operation among the hydraulic pump or air pressure pump 301 , the second pump body 602 and the heater 502 .

[0083] In this embodiment, the cleaning command set issued by the controller to the cleaning device of the vehicle-mounted camera can be divided into four categories:

[0084] 1. Only clean the lens surface by swinging, where the swing speed is adjustable (default medium speed is optional) to deal with water droplets or snowflakes on the lens surface in rainy and snowy weather.

[0085] Specifically, the controller sends a command of "only swing to clean the lens surface" to the cleaning device of the vehicle-mounted camera, and the hydraulic pump or pneumatic pump 301 starts to work. Under the combined action of the hydraulic pressure (or pneumatic pressure), the spring compression force, and the preload force of the cleaning strip 2, the cleaning strip 2 performs a reciprocating swinging motion to wipe the lens surface of the camera 7. By adjusting and controlling the frequency of the flow direction change of the hydraulic oil (or gas) by the hydraulic pump or pneumatic pump 301, the movement frequency and the number of wiping times of the cleaning strip 2 can be controlled.

[0086] 2. A combination of water spraying and swinging dust removal, with an adjustable swinging speed (optional default high speed), is used to remove water stains, stubborn dust and other dirt on the lens surface.

[0087] Specifically, the controller sends a "water spray and swing dust removal" command to the cleaning device of the vehicle-mounted camera. The nozzle 601 next to the lens of the camera 7 sprays a certain amount of cleaning agent under the action of the second pump body 602, and then the hydraulic pump or pneumatic pump 301 controls the cleaning scraper 2 to swing to complete the cleaning work.

[0088] 3. Combination of heating and swinging deicing, with adjustable swinging speed (optional default low speed), to deal with frost and ice on the lens surface.

[0089] Specifically, the controller sends a "heating and swinging deicing" command to the cleaning device of the vehicle-mounted camera, and the heater 502 controls the heating element 501 in the cleaning scraper 2 to generate heat. Under the joint action of the heater 502 and the monitoring logic of the temperature detection element, the temperature of the cleaning scraper 2 is safely and stably increased, and the hydraulic pump or pneumatic pump 301 is cooperated to control the swing of the cleaning scraper 2 to complete the ice, snow, frost and fog removal work.

[0090] 4. A combination of water spraying, heating and swinging for decontamination, with an adjustable swinging speed (optional default medium speed), can cope with extremely complex environments and cover all the above problem scenarios.

[0091] Specifically, the controller sends a "water spray, heating and swinging to remove dirt" command to the cleaning device of the vehicle-mounted camera. The water nozzle next to the lens of the camera 7 sprays a certain amount of detergent under the action of the second pump body 602. At the same time, the heater 502 controls the heating element 501 in the cleaning scraper 2 to heat up. After completing these two steps, the hydraulic pump or pneumatic pump 301 controls the cleaning scraper 2 to swing to complete the cleaning work.

[0092] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
