[0001] The utility model belongs to the technical field of timing devices, and specifically relates to a parking meter. Background Art

[0002] For people driving to urban commercial areas, office areas, etc., roadside parking spaces are usually a more convenient choice. A parking meter can accurately record the parking time, help you reasonably arrange parking within the specified time, and avoid being fined for parking. In some time-based charging parking lots, the parking meter can cooperate with the parking lot's charging system to ensure a clearer understanding of the parking fees.

[0003] The shape of a parking meter is usually a small electronic device that can be installed on the inner windshield of a vehicle. Its main components include a display screen, buttons, a control circuit, etc. Currently, the battery life of existing parking meters varies, and some need to be frequently replaced or charged after being used for a period of time, which brings inconvenience to users. Moreover, the installation method of some parking meters is not firm enough, and they may become loose or even fall off during vehicle driving. Therefore, a parking meter is proposed to solve the above problems. Summary of the Utility Model

[0004] In order to make up for the deficiencies of the prior art and solve the technical problems proposed in the background art, the utility model proposes a parking meter.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows: A parking meter of the utility model includes a timer display screen, the timer display screen is electrically connected to a circuit board, a processor is welded on the circuit board, the circuit board and the processor are powered by a battery, and the battery is connected to a solar panel through a wire; the parking meter also includes a quick-release clip and a quick-release clip base. Slide bars are provided on the outer walls on both sides of the quick-release clip, a chute is opened inside the quick-release clip base, the slide bars are inserted and removed corresponding to the chute, inner grooves are provided on both sides of the slide bars, springs are fixedly connected to the inner walls of the inner grooves, the other ends of the springs are fixedly connected to semi-circular bumps, outer grooves are opened on the inner side walls of the quick-release clip base, and the semi-circular bumps are clamped corresponding to the outer grooves. First adsorption parts are fixedly connected to both sides of the quick-release clip base, and a second adsorption part is fixedly connected to the bottom of the quick-release clip base.

[0006] Preferably, the quick-release clip base is of a U-shaped structure.

[0007] Preferably, when the spring is in a non-compressed state, the height of the semi-circular bump is less than the radius of the semi-circular bump, and the included angle between the semi-circular bump and the slide bar is greater than 90°.

[0008] Preferably, the first adsorption part and the second adsorption part are plastic adsorption stickers.

[0009] Preferably, the model of the processor is PIC16F883.

[0010] Preferably, the circuit board is welded with an adjustment button and a timer switch.

[0011] Preferably, the adjustment button is a round button and the timer switch is a toggle switch.

[0012] Advantages of the present utility model:

[0013] 1. The present utility model provides a parking timer. The quick-release clip base of the parking timer is fixed on the front windshield through the first adsorption part on the quick-release clip base. Since the vehicle often jolts during driving, it may fall off. At this time, the second adsorption part can greatly increase the suction force and make it more firmly adsorbed on the windshield. In this way, after the user parks the vehicle, the parking timer can be turned on through the timer switch in the vehicle, and then the user can leave with confidence. When the user comes back, the user can directly see the time displayed on the parking timer adsorbed on the windshield through the windshield. This design provides great convenience for both users and managers. It not only allows users to accurately master the parking time and reasonably arrange the itinerary, but also provides a convenient management tool for managers and improves the efficiency of parking management.

[0014] 2. The present utility model provides a parking timer. Through the battery fixedly connected to the back of the solar panel, since the display screen needs a stable power supply to work properly, if a conventional battery is used for power supply, once the battery fails to be replaced in time, the parking timer cannot be used. However, the parking timer stores energy through the solar panel and converts solar energy into electrical energy and stores it in the battery. In this way, the user does not need to frequently replace the battery and does not have to spend energy on replacing the battery. As long as there is sunlight, the parking timer can be continuously used until the battery is damaged or aged or the device is damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0025] The following gives specific embodiments.

[0026] Please refer to Figures 1 - 6, as shown in the figure, the present utility model provides a parking timer, which includes a timer display screen 11. The timer display screen 11 is electrically connected to a circuit board 21. The circuit board 21 is welded with a processor 113. The circuit board 21 and the processor 113 are powered by a battery 31. The battery 31 is connected to a solar panel 12 through a wire. The parking timer further includes a quick-release clip 13 and a quick-release clip base 14. Slide bars 17 are provided on the outer walls on both sides of the quick-release clip 13. Slide grooves 18 are formed on the inner side of the quick-release clip base 14. The slide bars 17 are inserted and removed corresponding to the slide grooves 18. Inner grooves 111 are provided on both sides of the slide bars 17. Springs 19 are fixedly connected to the inner walls of the inner grooves 111. The springs 19 are fixedly connected to semi-circular convex points 110. The height of the semi-circular convex points 110 in the non-compressed state of the springs 19 is less than the radius of the semi-circular convex points 110. Outer grooves 112 are formed on the inner side walls of the quick-release clip base 14. The semi-circular convex points 110 are engaged corresponding to the outer grooves 112. First adsorption parts 15 are fixedly connected to both sides of the quick-release clip base 14. Second adsorption parts 16 are fixedly connected to the bottom of the quick-release clip base 14. During operation, the user first firmly adsorbs the side of the quick-release clip base 14 of the parking timer with the adsorption part on the inner side of the windshield at a place that does not block the driver's view. After firm adsorption, the user holds the parking timer and aligns the slide bars 17 on both sides of the quick-release clip 13 with the slide grooves 18 of the quick-release clip base 14 and inserts them therein. At this time, the semi-circular convex points 110 provided on both sides of the quick-release clip 13 are squeezed, thereby compressing the springs. When the slide bars 17 reach the end of the slide grooves 18, the inner grooves 111 on both sides of the quick-release clip 13 exactly coincide with the outer grooves 112 on the inner wall of the quick-release clip base 14, and the springs 19 rebound, pushing the semi-circular convex points 110 into the outer grooves 112, thus realizing the fixation of the parking timer.

[0027] When the user parks the vehicle properly and needs to remove the parking meter from the quick-release clip base 14, since the height of the semi-circular bump 110 exposed after the spring 19 connected to the semi-circular bump 110 is fully extended is less than the radius of the hemisphere, and the angle between the semi-circular bump 110 and the horizontal direction is greater than 90°, at this time, the user can easily pull out the parking meter without expending too much effort. The parking meter can be started by the timer switch 42 on the back of the parking meter. After starting the parking meter, the display content before and after the colon can be switched by pressing the button corresponding to "F", and the time can be adjusted by pressing the button corresponding to "+", and after the adjustment is completed, pressing the button corresponding to "P" starts the timing. When the parking meter starts timing, the numbers on the timer display screen 11 start to count down. The timer display screen 11 is controlled by the processor 113 on the circuit board 21. This processor 113 is PIC16F883, which has the characteristic of low power consumption and is extremely suitable for the application scenario of parking meters with high power consumption requirements, can effectively reduce the energy consumption of the device and extend the service life of the battery. The timer display screen 11, the circuit board 21 and the processor 113 are all powered by the battery 31, and the battery 31 is connected to the solar panel 12. The solar panel 12 can continuously absorb external sunlight to charge the battery 31, and the user does not need to replace the battery 31 frequently, which greatly saves energy. Through the ingenious design of the first adsorption part 15, the second adsorption part 16, the semi-circular bump 110 and the outer groove 112 of the quick-release clip base 14, the parking meter can be firmly fixed on the windshield; and when it needs to be taken down, the small design that the semi-circular bump will not be fully exposed enables the user to easily remove it without too much effort, which provides great convenience for both the user and the management personnel. It not only enables the user to accurately master the parking time and reasonably arrange the itinerary, but also provides a convenient management tool for the management personnel and improves the efficiency of parking management.
