The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0021] For the description of the present utility model, non-limiting Figure 1 The marks "front", "rear", "up", "down", "left" and "right" shown in the figure are used to facilitate the understanding of the embodiment and are not intended to limit the present invention. Among them, the front-to-back direction represents the longitudinal direction, the left-to-right direction represents the transverse direction, and the up-down direction represents the vertical direction.

[0022] Figure 1-Figure 6 An embodiment of the license plate recognition device of the utility model is shown, including a shell 1, a recognition component 2 and a parking lot information prompting component 3. The recognition component 2 is located in the shell 1, and the parking lot information prompting component 3 is arranged on the side of the shell 1. The recognition component 2 includes a camera 21. A light-transmitting protective screen 11 is arranged on the shell 1 at a position corresponding to the camera 21. The camera 21 is used to recognize the license plate; the parking lot information prompting component 3 includes a light-emitting component 31 and a light-emitting shell 32. The light-emitting component 31 is arranged in the light-emitting shell 32. The light-emitting component 31 can display lights of different colors according to different vehicle conditions in the parking lot.

[0023] In the utility model, by arranging the parking lot information prompt component 3 on the side of the shell 1, when the parking spaces in the parking lot are full, the light-emitting component 31 of the parking lot information prompt component 3 emits red light; when there are vacant parking spaces in the parking lot, the light-emitting component 31 emits green light; by observing the light color of the light-emitting component 31 from a distance, the vehicle situation in the parking lot can be understood, which is convenient for the car owner to park.

[0024] It should be noted that the parking lot information prompting assembly 3 can be arranged only on one side of the housing 1, or can be arranged on both sides of the housing 1. When the parking lot information prompting assembly 3 is arranged on both sides of the housing 1, the car owner can observe the light from different angles to avoid visual blind spots. The light emitting element 31 can be an LED lamp, or an incandescent lamp, etc.

[0025] In some embodiments, Figure 5 and Figure 6As shown, the light-emitting housing 32 includes a fixing portion 321 and a light-transmitting portion 322, the fixing portion 321 is connected to the housing 1, the light-transmitting portion 322 is detachably connected to the fixing portion 321, a plurality of fixing plates 3211 are provided on the fixing portion 321, and the light-emitting element 31 is mounted on the fixing plates 3211. When the light-emitting element 31 needs to be repaired or replaced, the light-transmitting portion 322 is removed from the fixing portion 321, and the light-emitting element 31 can be taken out without disassembling the entire housing 1, which is more convenient and quick.

[0026] In some embodiments, Figure 5 As shown, the fixing portion 321 is provided with a connecting hole 3212 connected to the side of the housing 1.

When there is insufficient light around the camera 21, the fill light 24 is automatically turned on to illuminate the environment around the camera 21, making it convenient for the camera 21 to shoot the license plate.

[0032] In some embodiments, Figure 1As shown, the license plate recognition device further includes an information display screen 4, which is arranged in the middle of the housing 1 and is used to display the license plate information. When entering or leaving the parking lot, after the camera 21 recognizes the license plate, the license plate information or parking time and other information are displayed on the information display screen 4, and the owner can confirm the license plate information or parking time and other information to prevent the camera 21 from recognizing errors.

[0033] In some embodiments, Figure 1 As shown, the license plate recognition device further includes a lighting assembly 5, which is disposed at the lower front portion of the housing 1 and is used to illuminate the license plate. When a vehicle drives to the front of the license plate recognition device, the lighting assembly 5 located at the lower front portion of the housing 1 corresponds exactly to the position of the license plate, and the lighting assembly 5 illuminates the license plate, making it easier for the camera 21 to recognize the license plate.

[0034] In some embodiments, Figure 1 and Figure 2 As shown, the back and sides of the housing 1 are provided with heat dissipation holes 12, which can accelerate the heat dissipation of the internal equipment of the housing 1 and improve the performance of the internal equipment.

[0035] In some embodiments, Figure 2 As shown, a plurality of quickly detachable cover plates 13 are provided on the back of the housing 1. When the internal equipment needs to be repaired, the corresponding cover plates 13 can be quickly removed, which facilitates the repair of the internal equipment.

[0036] It can be seen that the utility model discloses a license plate recognition device, including a shell, a recognition component and a parking lot information prompt component, the recognition component is located in the shell, the parking lot information prompt component is arranged on the side of the shell, the recognition component includes a camera, a light-transmitting protective screen is arranged on the shell at a position corresponding to the camera, and the camera is used to recognize the license plate; the parking lot information prompt component includes a light-emitting component and a light-emitting shell, the light-emitting component is arranged in the light-emitting shell, and the light-emitting component can display different colors of light according to different vehicle conditions in the parking lot.
