[0002] With China's rapid economic development and the improvement of people's living standards and income, the number of private cars is increasing day by day, while the growth rate of parking spaces lags far behind the growth rate of private cars. This leads to private parking spaces often being occupied. To solve the problem of private parking spaces being occupied, parking space owners often purchase a ground lock and install it on their parking space to prevent others from occupying it.

[0003] Current parking locks are effective during the day, but at night, due to poor lighting, they are often unnoticed by outsiders. When others park in the space, their vehicles collide with the lock's barrier. These locks often integrate expensive license plate recognition cameras into the barrier; collisions can easily damage these cameras. This lack of protection for the cameras leads to frequent repairs, causing financial losses for both the parking space owner and the occupant. Furthermore, the lack of protection during repairs leaves the parking space unprotected, causing inconvenience for the owner. Summary of the Invention

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1: A smart parking lock for motor vehicle parking spaces, such as Figure 1 and Figure 3 As shown, it includes a base 11 and a cover 1 with a snap-on structure on the base 11. The cover 1 and the base 11 enclose an electrical component mounting chamber located inside the cover 1.

[0042] The base 11 has a fixing plate 12 at each of its four corners, and the fixing plate 12 has through screw holes at the top and bottom. When installing the base 11, the base 11 is fixed to the ground by driving bolts through the screw holes on the fixing plate 12 into the ground.

[0043] A controller is installed in the electrical component mounting chamber. In this embodiment, the controller is a programmable PLC controller.

[0044] The top plate of the cover 1 is equipped with a stop bar 3 and a rocker arm 5. The stop bar 3 is a strip-shaped plate structure that extends vertically, and the rocker arm 5 is a vertically arranged gate-shaped hollow tube structure.

[0045] The front panel of the gear lever 3 is equipped with a reflective strip 13, which can emit the headlights of oncoming vehicles to remind them when a vehicle is approaching.

[0046] A camera 14 and a second sensor 15 are embedded in the front panel of the rocker arm 5. The camera 14 and the stop lever 3 are installed in a staggered manner. Both the camera 14 and the second sensor 15 are electrically connected to the controller.

[0047] The second sensor 15 is used to detect an obstacle in front when the rocker arm 5 is raised to a vertical position. The camera 14 is then activated and begins to identify the license plate of the approaching vehicle.

[0048] In this embodiment, the sensing distance of the second sensor 15 should not be less than 1m to provide reaction time for parking personnel, and the sensing distance of the second sensor 15 should not exceed the front limit line of the parking space to avoid false alarms.

[0049] In order to prevent the stop lever 3 and rocker arm 5 from colliding with the outside world when they are rotated forward to a horizontal position and retracted, in this embodiment, as follows: Figure 1 and Figure 2 As shown, the top plate of the cover 1 is recessed inward to form a first placement groove 2 extending from front to back and two second placement grooves 4 that are symmetrical about the first placement groove 2. The depth of the first placement groove 2 is greater than the depth of the second placement groove 4.

[0050] The bottom of the stop lever 3 is hinged to the rear of the first placement groove 2. When the stop lever 3 is rotated forward to a horizontal position, the stop lever 3 is located in the first placement groove 2.

[0051] The bottom of the stop lever 3 has a semi-circular arc to reduce the clearance space reserved by the first placement groove 2 to avoid the bottom of the stop lever 3 when the stop lever 3 is rotated.

[0052] The second placement slot 4 is an inverted gate-shaped slot structure, and the front part of the second placement slot 4 is connected to the middle part of the first placement slot 2, while the rear part of the second placement slot 4 extends to the rear of the first placement slot 2.

[0053] The bottom of the rocker arm 5 is provided with a circular tube structure extending in the left and right direction, and the circular tube structure is hinged to the rear of the second placement slot 4; when the rocker arm 5 rotates forward to a horizontal state, the rocker arm 5 falls in the middle of the first placement slot 2 and in the two second placement slots 4.

[0054] The circular tube structure reduces the clearance space reserved in the second placement slot 4 to prevent interference with the rotation of the rocker arm 5, making the structure of the cover 1 more compact.

[0055] The rear panel of the rocker arm 5 is detachably connected to the main body of the rocker arm 5 with screws, so as to facilitate the quick repair and replacement of the camera 4 and the second sensor 15 at the inner end of the rocker arm 5 in the future.

[0056] The rear side plate I of the first placement slot 2 and the rear side plate I of the second placement slot 4 form a stop structure that limits the rearward rotation range of the stop bar 3 and the rocker arm 5. When the rear of the stop bar 3 and the rocker arm 5 abuts against the stop structure, the stop bar 3 and the rocker arm 5 are in a vertical state.

[0057] like Figure 4 As shown, the electrical component mounting cavity is provided with a first driving mechanism for driving the stop lever 3 to rotate and a second driving mechanism for driving the rocker arm 5 to rotate. The stop lever 3 can rotate backward to a vertical state and then rotate in the opposite direction to a horizontal state under the drive of the first driving mechanism. The rocker arm 5 can rotate backward to a vertical state and then rotate in the opposite direction to a horizontal state under the drive of the second driving mechanism.

[0058] Specifically, the first drive mechanism includes a first DC brake motor 17 and a first transmission gear assembly 18.

[0059] The first transmission gear assembly 18 includes a first driving gear and a first driven gear, with the first driving gear located on the output shaft of the first DC brake motor 17.

[0060] The first DC brake motor 17 is fixed on the base 11 and electrically connected to the controller.

[0061] The bottom of the stop bar 3 is fixedly provided with a first rotating shaft extending in the left and right direction. The left and right side walls of the first placement groove 2 are provided with a first shaft hole 23 that is open in the left and right directions. The end of the first rotating shaft passes through the first shaft hole 23 and rotates with the first shaft hole 23.

[0062] The first driven gear is fixedly mounted at one end of the first rotating shaft and meshes with the first driving gear, and the first driven gear is located in the electrical component mounting cavity.

[0063] The second drive mechanism includes a second DC brake motor 20 and a second transmission gear assembly 21.

[0064] The second transmission gear assembly 21 includes a second driving gear and a second driven gear, with the second driving gear located on the output shaft of the second DC brake motor 21.

[0065] The second DC brake motor 20 is fixed on the base 11 and electrically connected to the controller.

[0066] The bottom of the rocker arm 5 is fixed with a second rotating shaft extending in the left and right direction. The two adjacent and opposite side plates at the rear of the second placement groove 4 are provided with corresponding second shaft holes 24. The second rotating shaft 24 passes through the two second shaft holes 24.

[0067] The second driven gear is fixed on the second rotating shaft 24 and meshes with the second driving gear, and the second driven gear is located in the electrical component mounting cavity.

[0068] like Figure 1 As shown, a first sensor 8 is embedded in the front of the top plate of the cover 1 to sense the presence of an obstacle above. The first sensor 8 is located in front of the lever 3 when it is rotated forward to a horizontal state. The first sensor 8 is electrically connected to the controller. The first sensor 8 and the second sensor 15 operate alternately.

[0069] In this embodiment, both the first sensor 8 and the second sensor 15 are ultrasonic detectors.

[0070] The electrical component installation chamber is also equipped with a wireless transmitter and a wireless signal receiver, both of which are electrically connected to the controller.

[0071] The wireless transmitter is used to transmit the audio data from camera 14 to the cloud server for identification and judgment.

[0072] The wireless signal receiver is used to receive command signals transmitted from the cloud server and transmit the command signals to the controller.

[0073] A solar panel assembly 10 is embedded in the top plate of the cover 1, and the solar panel assembly 10 is electrically connected to the controller.

[0074] An LED indicator 6 capable of changing red and green colors is provided on the front of the top plate of the cover 1. The LED indicator 6 is electrically connected to the controller.

[0075] When the lever 3 is in the vertical position, the controller controls the LED indicator 6 to display red;

[0076] When the lever 3 is in a horizontal position, the controller controls the LED indicator 6 to display green.

[0077] The top plate of the cover 1 is fixedly equipped with a player 7. The top plate of the cover 1 is provided with several sound holes that are open from top to bottom. The sound holes correspond to the player 7 vertically. The player 7 is electrically connected to the controller.

[0078] A light-controlled lamp 9 is provided on the top plate of the cover 1, and the light-controlled lamp 9 is electrically connected to the controller;

[0079] When the second sensor 15 detects an obstacle in front and the photosensitive element in the light control lamp 9 detects that the ambient light intensity is lower than the preset light intensity, the light control lamp 9 is turned on to provide supplementary lighting for the camera 14 to take pictures.

[0080] Working principle: When the stop lever 3 and rocker arm 5 are in a vertical position, the first sensor 8 is turned off, the second sensor 15 is turned on, and the LED indicator 6 displays red.

[0081] When the second sensor 15 detects an obstacle in front, the controller controls the camera 14 to start taking pictures, and at the same time, the controller sends a supplementary light signal to the light control lamp 9. When the light control lamp 9 receives the supplementary light signal from the controller, the photoresistor in the light control lamp 9 performs a secondary detection of the ambient light intensity. When the ambient light intensity is detected to be lower than the preset light sensing intensity of the light control lamp 9, the light control lamp 9 turns on to provide supplementary light for the camera 14 to take pictures. If the ambient light intensity is detected to be higher than the preset light sensing intensity of the light control lamp 9, the light control lamp 9 does not turn on.

[0082] The wireless transmitter transmits the audio data from camera 14 to the cloud server for identification and judgment.

[0083] When the cloud server determines that the license plate number of the incoming vehicle belongs to the owner of the parking space, the cloud server sends an access signal to the wireless signal receiver. The wireless signal receiver sends the access signal to the controller, and the controller controls the lever 3 and rocker arm 5 to descend simultaneously, and the second sensor 15 is turned off.

[0084] Once the stop lever 3 has fallen into the first placement slot 2 and the rocker arm 5 has fallen into the second placement slot 4, the controller stops the operation of the first and second drive mechanisms. At this time, the controller controls the player 7 to start playing a voice message permitting the vehicle to enter the parking space, and the first sensor 8 starts working simultaneously.

[0085] When the first sensor 8 detects an obstacle above, the controller shuts down the player 7, and the LED indicator 6 turns green.

[0086] When the vehicle leaves the parking space, the first sensor 8 detects that the obstacle above has disappeared. The controller then controls the lever 3 and rocker arm 5 to rise to a vertical position, the first sensor 8 turns off, the second sensor 15 turns on, and the LED indicator 6 displays red.

[0087] When the cloud server determines that the license plate number of the approaching vehicle does not belong to the owner of the parking space, the cloud server sends an alarm signal to the wireless signal receiver. The lever 3 and rocker arm 5 remain in a vertical position, the LED indicator 6 turns red, and the controller controls the player 7 to issue an alarm voice warning and reminder.

[0088] Example 2: A smart parking lock for motor vehicle parking spaces. The difference between this example and Example 1 is that the LED indicator light 6 is no longer installed on the cover 1. All other structures are the same as in Example 1.

[0089] Example 3: A smart parking lock for motor vehicle parking spaces. This example differs from Example 1 in that the light-controlled lamp 9 is no longer installed on the cover 1, and the camera 14 is a high-definition night-view camera. All other structures are the same as in Example 1.

[0090] Example 4: A smart parking lock for motor vehicle parking spaces. This example differs from Example 1 in that the top plate of the cover 1 no longer has the first placement slot 2 and the second placement slot 4. Two hinge seats are spaced apart at the front and back of the top of the cover 1 for the hinged installation of the stop bar 3 and the rocker arm 5. Furthermore, a strip-shaped groove is formed in the top plate of the cover 1 for the first driven gear and the second driven gear to pass through the top plate of the cover 1 and enter the electrical component mounting chamber. All other structural features are the same as in Example 1.

[0091] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims and not by the foregoing description.
