Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

Example one

Referring to fig. 1, a schematic structural diagram of a parking spot lock of the present invention is shown, and as shown in fig. 1, the parking spot lock may specifically include: the device comprises a shell 10, a lock cylinder 11, an image recognition module 12, an obstacle recognition module 13, a first electromagnetic piece 14, a second electromagnetic piece 15 and a control module 16; wherein the content of the first and second substances,

an accommodating cavity 101 is arranged in the shell 10, the first electromagnetic part 14 is fixed at the bottom of the accommodating cavity 101, and the second electromagnetic part 15 is movably connected to the side wall of the accommodating cavity 101;

the lock cylinder 11 is arranged in the accommodating cavity 101, a magnetic structure 111 is arranged at the bottom of the lock cylinder 11, and a limit groove 112 is arranged on the side wall of the magnetic structure 111;

the image recognition module 12 is arranged on the outer side wall of the lock cylinder 11, and the obstacle recognition module 13 is arranged on the top of the lock cylinder 11;

the control module 16 is respectively connected with the image recognition module 12, the obstacle recognition module 13, the first electromagnetic piece 14 and the second electromagnetic piece 15, and the control module 16 can be used for controlling the first electromagnetic piece 14 to be electrified under the condition that the image recognition module 12 recognizes a target vehicle so as to retract the lock cylinder 11 into the accommodating cavity 101, and controlling the second electromagnetic piece 15 to be electrified under the condition that the obstacle recognition module 13 recognizes the target vehicle so as to enable the second electromagnetic piece 15 to be embedded into the limiting groove 111; in the case that the obstacle recognition module 13 does not recognize the target vehicle, the second electromagnetic member 15 is controlled to be powered off, so that the second electromagnetic member 15 is disengaged from the limiting groove 111, and the lock cylinder 11 protrudes from the accommodating cavity 101.

In practice, the parking spot lock may be installed in a parking spot, for example, at the front and rear 1/3 of the parking spot in the length direction. Specifically, the housing 10 of the parking lock can be embedded under the ground surface of the parking space. When the lock cylinder 11 of the parking lock extends out of the accommodating cavity 101 of the housing 10, the parking lock is locked, the lock cylinder 11 can form an obstacle to prevent a vehicle from entering the parking space, and when the lock cylinder 11 of the parking lock retracts into the accommodating cavity 101 of the housing 10, the parking lock is unlocked to remove the obstacle formed by the lock cylinder 11, so that the vehicle can conveniently enter the parking space.

For example, the diameter of the parking lock may be 10cm for easy installation. In order to enable the lock cylinder 11 to form an effective obstacle, the maximum height of the lock cylinder 11 from the ground may be about 50cm, and of course, in practical applications, a person skilled in the art may set the diameter of the parking lock and the maximum height of the lock cylinder 11 from the ground to other values according to actual needs.

In the embodiment of the present invention, when the parking space lock is installed in a parking space and no vehicle enters the parking space, the lock cylinder 11 may extend out of the accommodating cavity 101 of the housing 10, and the parking space lock may maintain a locked state. Since the image recognition module 12 is disposed on the outer side wall of the lock cylinder 11, the recognition of the target vehicle can be realized through the image recognition module 12, and after the target vehicle is recognized, the control module 16 can control the first electromagnetic element 14 to be powered. In practical application, because the first electromagnetic member 14 is fixed to the bottom of the accommodating cavity 101, the lock cylinder 11 is disposed in the accommodating cavity 101, and the bottom of the lock cylinder 11 is provided with the magnetic structure 111, when the first electromagnetic member 14 is powered, the first electromagnetic member 14 can generate an electromagnetic adsorption effect on the magnetic structure 111 at the bottom of the lock cylinder 11, so as to adsorb the lock cylinder 11 to the bottom of the accommodating cavity 101, so that the lock cylinder 11 retracts into the accommodating cavity 101, and the locking state of the parking space lock is released, so that the target vehicle can drive into the parking space.

In the embodiment of the present invention, since the obstacle identification module 13 is disposed at the top of the lock cylinder 11, the obstacle identification module 13 can be used to identify whether an obstacle exists at the top of the lock cylinder 11. In the case where the target vehicle enters the parking space, since the target vehicle is located on the parking lock, the target vehicle may form an obstacle that can be recognized by the obstacle recognition module 13.

In practical applications, the target vehicle may be identified by the obstacle identification module 13, and after the obstacle identification module 13 identifies the target vehicle, the target vehicle may be considered to have stopped at the parking space, and at this time, the control module 16 may control the second electromagnetic element 15 to be powered. Because second electromagnetism piece 15 swing joint is in the lateral wall that holds chamber 101, is equipped with spacing groove 112 on the lateral wall of magnetic structure 111, consequently, under the circumstances that second electromagnetism piece 15 got the electricity, second electromagnetism piece 15 can be to producing the electromagnetic adsorption effect between with magnetic structure 111, and second electromagnetism piece 15 can imbed spacing groove 111 in, carry on spacingly to lock core 11, keep the lock state of parking stall lock avoids lock core 11 to stretch out from holding chamber 101 and causes the damage to the target vehicle of berthing at this parking stall.

In the embodiment of the present invention, the obstacle recognition module 13 is used to recognize the obstacle at the top of the parking lock, and also can be used to determine whether the target vehicle drives away from the parking space. Specifically, in the case where the target vehicle is driven out of the parking space, the obstacle recognition module 13 will not recognize the target vehicle. In practical applications, in the case that the obstacle recognition module 13 does not recognize the target vehicle, the target vehicle may be considered to have driven away from the parking space, and at this time, the control module 16 may control the second electromagnetic element 15 to be powered off. Under the condition that the second electromagnetic part 15 is powered off, the electromagnetic adsorption between the second electromagnetic part 15 and the magnetic structure 111 is released, the second electromagnetic part 15 is separated from the limiting groove 111, the limiting on the lock cylinder 11 is released, so that the lock cylinder 11 extends out of the accommodating cavity 101, and the parking space lock is locked.

Therefore, the parking space lock provided by the embodiment of the invention can automatically identify the target vehicle, and control the parking space lock to unlock or lock according to the condition that the target vehicle enters or leaves the parking space, the automation degree is high, and the target vehicle can be prevented from being provided with electronic devices such as a Bluetooth sensor, so that the installation convenience of the parking space lock can be improved.

Optionally, the image recognition module 12 may be an image sensor, the image sensor may be integrated with a camera and an image processing chip, the camera may be configured to capture a picture of a vehicle close to a parking space, the image processing chip may be configured to extract and respectively identify license plate information in the vehicle picture, identify whether the vehicle close to the parking space is a target vehicle, and send a corresponding unlocking signal to the control module 16 when the vehicle close to the parking space is the target vehicle. The control module 16 may control the first electromagnetic member 14 to be energized according to the unlock signal.

In practical application, the parking space lock can be used for public parking spaces or self-service parking spaces, and the embodiment of the invention is not particularly limited to specific application occasions of the parking space lock.

For example, when the parking spot lock is used in a public parking spot matched with a charging facility, since the charging facility is mainly used for charging a new energy vehicle, and a license plate of the new energy vehicle is different from a license plate of a non-new energy vehicle (the license plate number of the new energy vehicle is one more than that of the non-new energy vehicle, and the license plate of the new energy vehicle is green, and the license plate of the non-new energy vehicle is non-green), after the image recognition system 12 recognizes the license plate of the new energy vehicle, it may be determined that the vehicle close to the public parking spot is a target vehicle, and at this time, the parking spot lock may be unlocked, so that the new energy vehicle can conveniently drive into the public parking spot. When the image recognition system 12 does not recognize the license plate of the new energy vehicle, it can be considered that no new energy vehicle is close to the parking space, and at this time, the parking space lock can keep a locked state, so that the parking space is prevented from being illegally occupied by the non-new energy vehicle.

For another example, when the parking spot lock is used in a self-service parking spot, the license plate number of the vehicle owner may be prestored in the image recognition system 12, so that after the image recognition system 12 recognizes the license plate number of the vehicle owner, the vehicle close to the parking spot may be considered as the target vehicle, and at this time, the parking spot lock may be unlocked, so that the vehicle of the vehicle owner can conveniently drive into the public parking spot. When the image recognition system 12 does not recognize the license plate number of the car owner, it can be considered that the car of the car owner is not close to the parking space, and at this time, the parking space lock can keep a locked state, so that the parking space is prevented from being illegally occupied by a user other than the car owner.

Referring to fig. 2, a schematic diagram of a signal transmitted by an obstacle recognition module of the present invention is shown, and referring to fig. 3, a schematic diagram of a signal received by an obstacle recognition module of the present invention is shown. As shown in fig. 2 and 3, the obstacle recognition module may be a radar sensor, and specifically, the radar sensor may include: separating element 130, diaphragm 131, vibration coil 132, permanent magnet 133 and control chip 134, permanent magnet 133 can form sealed cavity with diaphragm 131, and vibration coil 132 can set up in the cavity, control chip 134 is connected with vibration coil 132 electricity, under the circumstances that control chip 134 control vibration coil 132 circular telegram, can drive diaphragm 131 vibration, the orientation incident wave 135 is sent out to the parking stall lock top.

In the case that the target vehicle 20 is located at the top of the parking lock, the incident wave 135 is reflected by the target vehicle 20 or forms a reflected wave 136, and the control chip 134 may send a corresponding limit signal to the control module 16 after receiving the reflected wave 136. The control module 16 may control the second electromagnetic element 15 to be powered according to the limit signal, so as to limit the lock cylinder 11, and the parking space lock may keep a locked state.

In the absence of the vehicle 20 at the top of the parking lock, the incident wave 135 is not reflected, and the reflected wave 136 is not received by the control chip 134. In practical applications, the control chip 134 may send a corresponding release limit signal to the control module 16 in case that the reflected wave 136 is not received. The control module 16 can control the second electromagnetic part 16 to be powered off according to the limit releasing limit, and the second electromagnetic part is in contact with the limit of the lock cylinder 11, so that the parking space lock is enabled to release the locking state.

In an embodiment of the present invention, the parking spot lock may further include: a first elastic member 17 and a second elastic member 18; wherein, the first elastic piece 17 is respectively connected with the first electromagnetic piece 14 and the bottom of the lock core 11; the second elastic member 18 is connected to the second electromagnetic member 18 and the side wall of the accommodating chamber 101, respectively.

In practical applications, the first elastic member 17 may be used to provide a restoring force for the lock cylinder 11 to protrude from the receiving cavity, so that, in the case that the first electromagnetic member 14 is powered off and the electromagnetic attraction between the first magnetic member 14 and the magnetic structure 111 is lost, the first elastic member 17 may provide the restoring force for the lock cylinder 11 to protrude from the receiving cavity 101, so that the lock cylinder 11 may protrude from the receiving cavity 101. The second elastic element 18 can be used to provide a restoring force for the second electromagnetic element 15 to be released from the position-limiting groove 112, so that, when the second electromagnetic element 15 is powered off and the electromagnetic attraction between the second magnetic element 15 and the magnetic structure 111 is lost, the second elastic element 18 can provide a restoring force for the second electromagnetic element 15 to be released from the position-limiting groove 112, so that the second electromagnetic element 15 can be released from the position-limiting groove 112, and the position limitation on the lock cylinder 11 is released.

Specifically, the first elastic member 17 and the second elastic member 18 may be at least one of a spring, an elastic sheet, and other elastic members, and the specific types of the first elastic member 17 and the second elastic member 18 may not be limited in the embodiment of the present invention.

Alternatively, a groove 102 is formed on a sidewall of the receiving chamber 101, and the second electromagnetic member 15 may be coupled in the groove 102 by the second elastic member 18.

In practical applications, in a case where the second electromagnetic element 15 is powered off and the electromagnetic attraction between the second magnetic element 15 and the magnetic structure 111 disappears, the second elastic element 18 may provide a restoring force to the second electromagnetic element 15, so that the second electromagnetic element 15 may be pulled out from the limiting groove 112 and retracted into the groove 102, so as to prevent the second electromagnetic element 15 from protruding out of the sidewall of the accommodating cavity 101 to hinder the extending movement of the lock cylinder 11.

In an optional embodiment of the present invention, the parking spot lock may further include: a delay module (not shown in the figure); the delay module is connected to the control module 16 and the first electromagnetic element 14, respectively, and the delay module 16 may be configured to control the first electromagnetic element 14 to be powered off after the first electromagnetic element 14 is powered on for a preset time.

In practical applications, in the case that the image recognition module 12 recognizes the target vehicle, the first electromagnetic element 14 may be powered to retract the lock cylinder 11 into the accommodating cavity 101, so that the target vehicle can enter the parking space. When the obstacle identification module 13 identifies that the vehicle with the target enters the parking space, the second electromagnetic member 15 can be powered to limit the lock cylinder 11, so that the lock cylinder 11 can keep the state of retracting in the accommodating cavity 101, at the moment, the delay module can control the first electromagnetic member 14 to be powered off, and therefore on one hand, electric energy can be saved, on the other hand, when the first electromagnetic member 14 is powered off, the retracting state of the lock cylinder 11 is only kept by the limit of the second electromagnetic member 15 on the lock cylinder 11, and when the second electromagnetic member 15 is powered off and the limit of the lock cylinder 11 is released, the lock cylinder 11 can automatically extend out of the accommodating cavity 101, and the automation degree of the parking space lock is further improved.

In the embodiment of the invention, the preset time can be set according to the actual situation. For example, the preset time may be longer than the time from when the target vehicle enters the shooting range of the parking space lock to when the target vehicle finally stops at the parking space, so that after the first electromagnetic element 14 is powered for the preset time, it is ensured that the vehicle has stopped at the parking space lock and is recognized by the obstacle recognition module 13, at this time, the second electromagnetic element 15 is powered and limits the lock cylinder 11, and damage to the target vehicle caused by the lock cylinder 11 protruding from the accommodating cavity 101 can be avoided.

In practical applications, a person skilled in the art may set a specific value of the preset time according to actual needs, for example, the preset time may be 30 seconds, 60 seconds, 100 seconds, or the like, and the specific value of the preset time may not be limited in the embodiment of the present invention.

In another alternative embodiment of the present invention, the first and second electromagnetic members 14 and 15 may be both electromagnetic relays. In practical applications, the electromagnetic relay may be powered on to generate an electromagnetic field when powered on, so as to form an attraction effect on the magnetic structure 111.

Specifically, the magnetic structure 111 may be made of a material capable of being magnetically attracted, such as a magnet, magnetic steel, and the like, and the specific material of the magnetic structure 111 in the embodiment of the present invention may not be limited.

It is understood that the first electromagnetic element 14 and the second electromagnetic element 15 may also be other elements capable of generating an electromagnetic field when energized, such as coils or the like. The specific types of the first electromagnetic member 14 and the second electromagnetic member 15 in the embodiment of the present invention may not be limited.

To sum up, the parking spot lock of the embodiment of the invention at least comprises the following advantages:

in the embodiment of the invention, the identification of the target vehicle can be realized through the image identification module, the lock cylinder can be controlled to retract into the accommodating cavity after the target vehicle is identified, so that the target vehicle can enter a parking space, whether the target vehicle stops at the parking space is identified through the obstacle identification module at the top of the lock cylinder, the target vehicle can be considered to stop at the parking space under the condition that an obstacle is identified at the top of the lock cylinder, and at the moment, the control module can control the second limiting part to be embedded into the limiting groove on the lock cylinder to limit the lock cylinder, so that the lock cylinder is limited in the accommodating cavity. When the obstacle recognition system recognizes that the target vehicle drives away from the parking space, the control module can control the second electromagnetic piece to be pulled out of the limiting groove, and the limiting on the lock cylinder is released, so that the lock cylinder extends out of the accommodating cavity. Therefore, the parking space lock provided by the embodiment of the invention can automatically identify the target vehicle, and control the parking space lock to unlock or lock according to the condition that the target vehicle enters or leaves the parking space, the automation degree is high, and the target vehicle can be prevented from being provided with electronic devices such as a Bluetooth sensor, so that the installation convenience of the parking space lock can be improved.
