[0002] An existing electronic device is signal-connected to a cloud system. The electronic device is suitable for installation on a curb next to a parking space. The curb extends along the length of the parking space. The electronic device includes a housing disposed on the curb and a camera module disposed within the housing for capturing license plates. The camera module has a window disposed on the housing and facing the parking space, and a lens disposed on the housing and obliquely projecting light onto the parking space through the window. The electronic device uses the lens to capture the license plate of a vehicle in the parking space and transmits the captured image to the cloud system, which can then identify the license plate number and calculate the parking time and parking fee for the vehicle.

[0003] However, dust, leaves, debris, or rainwater forming convex lens droplets on the window can obscure the lens and reduce the camera module's recognition ability. Therefore, manual cleaning of the window is required regularly, increasing maintenance costs and making it quite inconvenient to use. Thus, the electronic device suffers from the problem that the camera module is easily dirtied, obscured by debris, or contaminated by rainwater, resulting in poor image quality.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] See Figures 1 to 3 An embodiment of the electronic device 100 for curb stones of the present invention includes a housing 1, a camera unit 2, an air blowing unit 3, a flow guide 4, a micro switch 5, and a housing cover 6.

[0025] See Figures 3 to 5The housing 1 includes a rear sidewall 11, a front sidewall 12 located in front of the rear sidewall 11 along a front-rear direction Y, a first sidewall 13 connected between the rear sidewall 11 and the front sidewall 12, a second sidewall 14 connected between the rear sidewall 11 and the front sidewall 12 and spaced from the first sidewall 13 along a left-right direction X perpendicular to the front-rear direction Y, a first partition wall 15 connected between the rear sidewall 11 and the front sidewall 12 and located between the first sidewall 13 and the second sidewall 14, and a partition wall 15 connected to the rear sidewall 11. The rear sidewall 11, the front sidewall 12, the first partition wall 15, and the second sidewall 14 are connected by a second partition wall 16 between the sidewall 11 and the front sidewall 12 and between the first partition wall 15 and the second sidewall 14; a bottom wall 17 is connected to the lower side of the rear sidewall 11, the front sidewall 12, the first partition wall 15, and the second partition wall 16 along a vertical direction Z; and a top wall 18 is connected to the upper side of the rear sidewall 11, the front sidewall 12, the first sidewall 13, the second sidewall 14, the first partition wall 15, and the second partition wall 16 along a vertical direction Z. The first sidewall 13, the second sidewall 14, the first partition wall 15, and the second partition wall 16 are spaced apart from each other along the horizontal direction X.

[0026] The front sidewall 12 has a middle front wall portion 121 located in front of the rear sidewall 11, a first connecting wall portion 122 connecting the first sidewall 13, a first front wall portion 123 extending obliquely from the first connecting wall portion 122 opposite to the first sidewall 13 to the middle front wall portion 121, a second connecting wall portion 124 connecting the second sidewall 14, and a second front wall portion 125 extending obliquely from the second connecting wall portion 124 opposite to the second sidewall 14 to the middle front wall portion 121. The middle front wall portion 121, the first front wall portion 123, and the second front wall portion 125 together define a cavity 126.

[0027] An air outlet 1231 is formed on the first front wall portion 123, adjacent to the intermediate front wall portion 121 and communicating with the cavity 126. Two air inlets 1221 are formed on the first connecting wall portion 122, spaced apart along the left-right direction X, and a mounting opening 1222 is located between the air outlet 1231 and the air inlets 1221. The air inlets 1221 extend obliquely toward the air outlet 1231 relative to the front-back direction Y. It should be noted that in other variations of this embodiment, the number of air inlets 1221 is not limited; the number of air inlets 1221 may be one or more.

[0028] A camera port 1251 is formed on the second front wall portion 125, which communicates with the cavity 126 and faces the air outlet 1231 along the left-right direction X.

[0029] The first partition wall 15 includes a partition portion 151 connecting the rear sidewall 11, and an inclined wall portion 152 extending obliquely from the partition portion 151 on the side opposite to the rear sidewall 11 to the intermediate front wall portion 121. The inclined wall portion 152 and the first front wall portion 123 extend towards the air outlet 1231 in a tapering manner.

[0030] The second partition wall 16 is connected between the rear side wall 11 and the second connecting wall portion 124.

[0031] The bottom wall 17, the rear side wall 11, the front side wall 12, the first side wall 13, and the second side wall 14 together define an accommodating space 10 opposite to the cavity 126. The first partition wall 15 and the second partition wall 16 divide the accommodating space 10 into a central area 101, a first area 102, and a second area 103.

[0032] The central area 101 is located between the bottom wall 17, the rear side wall 11, the first partition wall 15, the second partition wall 16 and the front side wall 12 and is connected to the camera port 1251.

[0033] The first zone 102 is located between the rear side wall 11, the first partition wall 15, the first side wall 13 and the first connecting wall portion 122 and communicates with the air outlet 1231, the air inlet 1221 and the mounting port 1222.

[0034] The second zone 103 is located between the rear sidewall 11, the second partition wall 16, the second sidewall 14 and the second connecting wall portion 124.

[0035] Part of the top wall 18 is located above the cavity 126. The top wall 18 has a central opening 181 communicating with the central region 101, a first opening 182 communicating with the first region 102, and a second opening 183 communicating with the second region 103.

[0036] The camera unit 2 is disposed in the central area 101 and adjacent to the camera port 1251. The camera unit 2 includes a window 21 disposed in the camera port 1251 and a lens 22 that faces the camera port 1251 at an angle relative to the front-back direction Y towards the air outlet 1231.

[0037] The air blowing unit 3 includes a mounting base 31 detachably mounted to the first area 102 via the mounting port 1222, and a fan 32 disposed on the mounting base 31 and facing the air outlet 1231. The inclined wall portion 152 of the first partition wall 15 is located between the camera unit 2 and the air blowing unit 3. The fan 32 abuts against the partition portion 151, and the air inlet 1221 is located between the fan 32 and the first side wall 13. The fan 32 guides airflow from the air inlet 1221 into the first area 102 and blows it out towards the camera port 1251 through the air outlet 1231.

[0038] The air guide 4 extends along the vertical direction Z and is disposed at the air outlet 1231, and includes two through slots 41 that connect to the first area 102 and are used to smoothly guide the airflow blown by the fan 32 to the camera port 1251. The air guide 4 can be deflected and rotated about an axis (not shown) parallel to the vertical direction Z to change the orientation of the through slots 41.

[0039] The micro switch 5 is disposed at the top of the second partition wall 16 and partially housed in the second area 103. The micro switch 5 is electrically connected to a remote control unit (not shown).

[0040] The lid 6 covers the box body 1 to cover the accommodating space 10. The lid 6 includes a waterproof pad 61 detachably disposed in the central opening 181 to close the central area 101, and a cover 62 covering the box body 1 and covering the waterproof pad 61, the first opening 182, and the second opening 183. The waterproof pad 61 is made of rubber to prevent rainwater or sewage from seeping into the central area 101 and causing damage to the camera unit 2. The cover 62 is detachably locked to the top wall 18 by multiple screws and is detachably in contact with the micro switch 5. When the cover 62 touches the micro switch 5, the user can know through the remote control unit that the electronic device 100 for the curbstone is operating normally. When the micro switch 5 is not touched, the user can know through the remote control unit that the cover 62 may have been removed or loosened by external impact, and can further go to the site to check the electronic device 100 for the curbstone.

[0041] Since the first partition wall 15 separates the central area 101 where the camera unit 2 is located from the first area 102 where the air blowing unit 3 is located, when the waterproof pad 61 covers the central opening 181, the central area 101 forms an independent space with good sealing, which can further prevent water vapor or dust from the first area 102 from entering the central area 101 and contaminating the camera unit 2.

[0042] See Figures 4 to 6 When the fan 32 is started, it can guide the gas outside the housing 1 into the first area 102 through the air inlet 1221 and blow it to the guide member 4. When the gas passes through the guide member 4, it is guided by the through groove 41 and blown through the cavity 126 to the camera port 1251 to remove dirt, obstructions or water droplets adhering to the window 21. Since the inclined wall portion 152 and the first front wall portion 123 gradually extend towards the air outlet 1231, the airflow of the fan 32 can be further concentrated to the guide member 4. It should be noted that in this embodiment, the direction facing the through groove 41 can also be changed by rotating the guide member 4 to adjust the blowing direction of the airflow blown by the fan 32.

[0043] See Figure 7 The electronic device 100 for the curbstone can be installed on a curbstone 7 next to a parking space 8. When a vehicle 9 is about to park in the parking space 8, the camera unit 2 can capture an image of a license plate 91 of the vehicle 9 from the front or rear and transmit it to a cloud system (not shown) to identify the license plate number on the license plate 91 and calculate the parking time and parking fee for the vehicle 9. It should be noted that in other variations of this embodiment, the camera unit 2 can also be replaced with a projection device to project images or text onto the ground or a nearby wall through the camera port 1251 for advertising or government promotion purposes.

[0044] In summary, the electronic device 100 for curb stones of the present invention, by blowing air from the fan 32 through the air outlet 1231 toward the camera port 1251, can automatically remove dust, leaves, debris, or rainwater adhering to the window 21. Furthermore, the airflow output by the fan 32 can be guided to the camera port 1251 through the air guide 4, further concentrating the airflow to improve the cleaning effect and reducing the cost of manual cleaning and maintenance. Therefore, the purpose of the present invention is indeed achieved.

[0045] The above description is merely an embodiment of the present invention and should not be construed as limiting the scope of the present invention. Any simple equivalent changes and modifications made in accordance with the claims and description of the present invention shall still fall within the scope of the present invention.
