[0002] With the continuous enhancement of my country's comprehensive national strength, the continuous improvement of its international status, and the continuous improvement of people's living standards, private cars have generally become an important means of transportation for the general public. Many car owners will purchase dedicated parking spaces in underground parking lots, but the dedicated parking spaces of car owners are often occupied. Therefore, people have thought of installing a protection device on the parking space, that is, a parking lock. When the owner and the car are not there, the parking space is locked through the parking lock to ensure that other vehicles cannot enter the parking space. In addition, parking locks are usually installed in open parking spaces such as roads to facilitate the management personnel to charge fees.

[0003] The existing parking lock has a low structural strength. After being hit by an external vehicle, it is easy to deform and affect the life of the parking lock. In addition, when reversing into a garage, the driver cannot see the status of the ground lock due to the hood blocking the front of the car, which is prone to collision. Summary of the invention

DETAILED DESCRIPTION

[0044] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0045] like Figure 1-5The figure is a schematic diagram of the structure of the cross-type parking lock of the present invention, which includes a base plate 1, a locking arm 12, a rotating mechanism, a driving mechanism, an upper limit mechanism and a lower limit mechanism. The driving mechanism is fixed at the bottom of the base plate 1, and is used to drive the two locking arms 12 at the top of the base plate 1 to rotate inward or outward synchronously. The upper limit mechanism is arranged on the inner side of the two locking arms 12, and is used to prevent the locking arms 12 from shifting when crossing, thereby breaking the locking arms 12. The lower limit mechanism is fixed at the bottom of the base plate 1, and is used to adjust the rotation angle of the locking arms 12.

[0046] The parking lock has two modes: locking and entering. When it is in the locking mode, the driving mechanism drives the two locking arms 12 to rotate outward until they cross, and the two locking arms 12 are pressed against each other on the opposite sides to improve their anti-deformation ability. Moreover, the side of the locking arms 12 that press against each other is the side with a larger area of ​​the locking arms 12, ensuring a larger contact area, thereby improving the mutual friction and anti-deformation ability. When it is in the entering mode, the driving mechanism drives the two locking arms 12 to rotate inward until they press against the upper surface of the bottom plate 1, so that the vehicle can enter the parking space easily.

[0047] The guard plate 2 is integrally connected to the bottom of the base plate 1 in a shape-matched manner, and is used to protect the internal driving mechanism and lower limit mechanism thereof, and prevent external dust, fallen leaves, etc. from affecting the normal operation of the internal mechanism.

[0048] like Figure 7 , 8 As shown, the rotating mechanism includes a first baffle plate 8, a second baffle plate 9, a retaining groove 10, a locking bar 11, an extension plate 13, a fixing hole 14, a guide column 15, a guide hole 16 and a shield 17. There are two first baffle plates 8 and they are spaced apart. The second baffle plate 9 is integrally connected to the same side of the two first baffle plates 8. The two first baffle plates 8 and the second baffle plates 9 form a "]"-shaped structure, and a retaining groove 10 for installing the locking bar 11 is formed between the two first baffle plates 8.

[0049] The lock bar 11 is rotatably installed between the two first baffles 8 via a rotating shaft. The width of the lock bar 11 is equal to the distance between the two first baffles 8. When the driving mechanism drives the lock bar 11 to rotate, the first baffles 8 on both sides limit the rotating lock bar 11 to prevent the lock bar 11 from swinging to both sides during rotation. Moreover, when the driving mechanism drives the lock bar 11 to rotate to the vehicle locking mode (that is, the two lock arms 12 rotate outward to cross each other), when an external vehicle hits the lock arm 12, the presence of the first baffle 8 can improve the structural strength of the bottom of the lock bar 11 to prevent it from being deformed by the impact.

[0050] The locking arm 12 is inserted into the locking bar 11 and fixed to the locking bar 11 by screw fastening. The split structural design is convenient for maintenance and takes into account both efficiency and strength.

[0051] The locking arm 12 is made of polyurethane. On the one hand, the elasticity of polyurethane is utilized. When a vehicle accidentally hits the locking arm 12, the surface of the vehicle will not be scratched, thereby avoiding damage to the vehicle and causing unnecessary disputes. On the other hand, the higher hardness of polyurethane is utilized to improve the structural strength of the locking arm 12 to prevent it from being deformed by impact.

[0052] The extension plate 13 is integrally connected to the outer bottom of the first baffle 8 and is fixed to the base plate 1 by screwing (the screws pass through the base plate 1 from bottom to top and are fixed to the extension plate 13, which increases the difficulty of disassembly and avoids human damage to the parking lock).

[0053] The fixing hole 14 vertically penetrates the bottom plate 1, the guide column 15 is integrally connected to the extension plate 13 and extends to the upper and lower sides of the extension plate 13, and the guide hole 16 vertically penetrates the guide column 15. During the actual installation, the guide column 5 is first inserted into the fixing hole 14 of the bottom plate 1, and the fastening screw is passed from the bottom to the top of the bottom plate 1 and fixed on the extension plate 13 to achieve the fixation of the bottom plate 1 and the extension plate 13; then the expansion bolt is passed through the guide hole 16 and fixed on the ground. The setting of the guide hole 16 guides the inserted expansion bolt to avoid the expansion bolt from being crooked.

[0054] Finally, the shield 17 is buckled on both sides of the first baffle 8, and then the shield 17 is fixed to the first baffle 8 by screwing to protect the internal expansion bolts and avoid artificial damage to the parking lock.

[0055] There are two mounting holes 29, which are opened on the side of the locking arm 12 away from the locking bar 11. The ultrasonic rangefinder is fixed in the mounting hole 29. The double-headed ultrasonic rangefinder is used to detect the distance above to determine whether there is a vehicle. The double-headed rangefinder is more accurate and the detection data is more accurate, which can prevent the locking arm 12 from damaging the vehicle.

[0056] The driving mechanism is installed at the bottom of the base plate 1 to drive the locking arm 12 to rotate. Figure 5 , 6 As shown, the driving motor 3 is fixed on the top of the bottom plate 1, the driving gear 4 is installed on the bottom of the bottom plate 1 and connected to the driving motor 3, and the driving gear 4 is driven to rotate by the driving motor 3. The driven wheel 5 is rotatably installed at the bottom of the bottom plate 1 through the rotating shaft, and the convex teeth 6 are arranged on the outer circumference of the driven wheel 5 and mesh with the driving gear 4. The driving motor 3 drives the driving gear 4 to rotate, thereby driving the driven wheel 5 to rotate.

[0057] One side of the connecting plate 19 is rotatably mounted on the driven wheel 5 via a rotating shaft, and the connecting column 20 is fixed to the side of the connecting plate 19 away from the driven wheel 5. The connecting block 21 is fixed to the end of the connecting column 20 away from the connecting plate 19, and the connecting groove 22 passes through the connecting block 21 for installing the connecting plate 18. The connecting plate 18 is fixed to the bottom of the locking bar 11 and is located in the connecting groove 22, and the pivot 23 passes through the connecting block 21 and the connecting plate 18, and the connecting block 21 and the connecting plate 18 are rotatably connected through the pivot 23.

[0058] The anti-dropout block 24 is integrally connected to one end of the pivot 23, and the diameter of the anti-dropout block 24 is larger than the diameter of the pivot 23, so as to prevent the pivot 23 from dropping out from one side of the coupling block 21. The first through hole 25 passes through the end of the pivot 23 away from the anti-dropout block 24, and the latch 26 is inserted into the first through hole 25 by means of interference fit, so as to prevent the pivot 23 from dropping out from the other side of the coupling block 21.

[0059] The pull post 27 is fixed to the bottom of the base plate 1, and a spring hole is provided on the pull post 27. A hook at one end of the pull spring 28 is hooked in the spring hole of the pull post 27, and a hook at the other end of the pull spring 28 is hooked in the first through hole 25 of the pivot 23. The tension spring 28 is provided to facilitate resetting the locking arm 12.

[0060] The lower limit mechanism includes a first limit switch 30, a first adjustment slot 31, a first fastener 32, a second limit switch 33, a second adjustment slot 34, a second fastener 35 and a contact block 36. Figure 5 As shown, the first limit switch 30 and the second limit switch 33 are respectively fixed at the bottom of the base plate 1 and are arranged around the outer side of the driven wheel 5, the first adjustment groove 31 passes through the first limit switch 30, and the first fastener 32 (the first fastener 32 is a fastening screw) passes through the first adjustment groove 31 and is fixed on the base plate 1. The first adjustment groove 31 is arc-shaped and its axis coincides with the axis of the driven wheel 5.

[0061] When adjusting the position of the first limit switch 30, first loosen the first fastener 32, and then the position of the first limit switch 30 can be adjusted. Since the first adjustment groove 31 is arc-shaped, the adjustment trajectory of the first limit switch 30 is an arc-shaped trajectory. After adjustment, it can still be ensured that the contact block 36 and the first limit switch 30 can cooperate.

[0062] There are at least two first adjustment slots 31 , and when the first limit switch 30 is rotated to adjust its position, the first limit switch 30 is prevented from swinging to both sides to affect the contact with the contact block 36 .

[0063] The second adjustment slot 34 penetrates the second limit switch 33, and the second fastener 35 (the second fastener 35 is a fastening screw) passes through the second adjustment slot 34 and is fixed on the bottom plate 1. The second adjustment slot 34 is arc-shaped and its axis coincides with the axis of the driven wheel 5.

[0064] When adjusting the position of the second limit switch 33, first loosen the second fastener 35, and then the position of the second limit switch 33 can be adjusted. Since the second adjustment groove 34 is arc-shaped, the adjustment trajectory of the second limit switch 33 is an arc-shaped trajectory. After adjustment, it can still be ensured that the contact block 36 and the second limit switch 33 can cooperate.

[0065] There are at least two second adjustment slots 34 , and when the second limit switch 33 is rotated to adjust its position, the second limit switch 33 is prevented from swinging to both sides to affect the contact with the contact block 36 .

[0066] The upper limit mechanism is arranged between the two locking arms 12 to prevent the locking arms 12 from shifting when crossing and thus preventing the locking arms 12 from breaking. The locking slot 37 is provided in the locking arm 12, and the through hole 38 is provided at the bottom of the locking arm 12 and communicates with the locking slot 37. The through hole 38 is used for passing the pull rope 43, and then when the locking arm 12 is fully opened, it is used to pull the locking arm 12 to prevent the locking arm 12 from shifting when crossing. The buckle cover 44 is inserted on one side of the locking arm 12 to facilitate the maintenance and replacement of the internal pull rope 43.

[0067] like Fig. 9 , 10 As shown, the slot 41 is provided at the top of the column 39, and the inner wall of the slot 41 is provided with an internal thread, and the second through hole 40 horizontally penetrates the column 39 and is connected with the slot 41. The pull rope 43 is passed through the second through hole 40 of the column 39, and the outer peripheral surface of the pressure rod 42 is provided with an external thread matching the slot 41. By screwing the pressure rod 42, the pull rope 43 is pressed into the slot 41 to prevent the pull rope 43 from loosening.

[0068] To prevent the parking lock from being damaged by human intervention, the pull rope 43 is a steel wire rope. There are two clamping columns 39, which are respectively arranged in the lock slots 37 of the two lock arms 12. The driving mechanism drives the two lock arms 12 to rotate outward until they cross, and the two sides of the two lock arms 12 are pressed against each other to improve their anti-deformation ability. At the same time, the pull rope 43 is straightened, and the side wall of the clamping column 39 is clamped on the inner side wall of the lock arm 12 to straighten the pull rope 43.

[0069] The slot 45 penetrates the bottom plate 1, and the bottom of the motor cover 46 is integrally provided with a plug-in plate 47 that matches the slot 45. During actual installation, the plug-in plate 47 is inserted into the slot 45 to protect the internal drive motor 3. Fig.11 As shown, the protrusion 48 is integrally connected to the bottom of one of the plug plates 47 and extends outward to buckle the motor cover 46 in the slot 45 to prevent the motor cover 46 from falling. When the motor cover 46 is actually installed, the protrusion 48 is first inserted into the slot 45, and then the motor cover 46 is rotated until the plug plate 47 is inserted into the slot 45.

[0070] The locking arms 12 on both sides are driven to rotate by the driving mechanism. When it is in the car locking mode, the driving mechanism drives the two locking arms 12 to rotate outwards until they cross, and the opposite sides of the two locking arms 12 are pressed against each other. When an external vehicle enters the parking space, the two locking arms 12 are pressed against each other. When the vehicle contacts and squeezes one of the locking arms 12, the other locking arm 12 will support the locking arm 12 to avoid its deformation and damage to the parking lock; when it is in the car entry mode, the driving mechanism drives the two locking arms 12 to rotate inwards until they are pressed against the upper surface of the bottom plate 1, making it convenient for the vehicle to enter the parking space.

[0071] like Fig.12 , which is a schematic diagram of the structure of the parking system, the parking system includes a parking lock, a fixing frame 49, a camera 50 and a signal light 51. The fixing frame 49 is fixed to one side of the parking space, a parking lock is fixedly installed on each parking space, and a camera 50 is fixed on the top of the fixing frame 49, and one camera corresponds to two parking spaces (i.e., the shooting area of ​​one camera 50 covers two parking locks).

[0072] There are two signal lights 51, which are fixed on the side of the fixing frame 49 close to the parking space and are distributed on both sides of the camera 50. Fig.12 As shown, the signal light on the left corresponds to the parking lock on the left, and the signal light on the right corresponds to the parking lock on the right. The working status of the left parking lock is displayed by the signal light 51 on the left, and the working status of the right parking lock is displayed by the signal light 51 on the right.

[0073] The camera 50 and the ultrasonic rangefinder form a dual recognition system to ensure that vehicles are safer when entering and exiting the parking lot, avoiding collisions with parking locks and causing damage to the vehicle; and the timing of vehicle parking is also more accurate, ensuring more precise charging.

[0074] The camera 50 faces the parking space and covers the entire parking space, and is used to identify the status of the vehicle within the range; the ultrasonic rangefinder is used to detect the height of the vehicle driving in from above. Only when the position of the vehicle does not change within the shooting range of the camera 50, and the height above detected by the ultrasonic rangefinder does not change within the specified time, can it be said that the vehicle is parked steadily in the parking space, and the time-based charging will be applied.

[0075] Because different drivers have different driving habits and driving abilities, some drivers may park their vehicles steadily in the parking space in one go, while some drivers may need to constantly adjust the steering wheel. If only relying on the camera 50 for single recognition, it is not conducive to the parking experience of people with low driving skills. In addition, some drivers park their cars in the parking space, and the position of the vehicle does not change within the shooting range of the camera 50, but the driver may drive away immediately due to an emergency. At this time, if only relying on the camera 50 for single recognition, it will cause additional charges to the user.

[0076] It has five working states:

[0077] Working state 1: when the locking arm 12 is fully opened, the signal light 51 is always red, indicating that the parking space is locked and parking is not allowed at present, otherwise the vehicle will be damaged;

[0078] Working state 2: when the lock arm 12 is completely closed and the dual recognition systems recognize the vehicle (i.e. the position of the vehicle does not change within the shooting range of the camera 50, and the height above the vehicle detected by the ultrasonic rangefinder does not change within the specified time), it indicates that the vehicle has stopped above the parking lock. At this time, the signal light 41 is always green, indicating that the vehicle has parked in the parking space, and timing can be started, thereby improving the accuracy of timing and avoiding additional charges;

[0079] Working state three: when the lock arm 12 is in the process of descending or ascending (when the lock arm 12 is in the process of descending, it means that someone wants to park in the parking space and is unlocking the parking space; when the lock arm 12 is in the process of ascending, it means that the last car has left and the parking lock is about to lock the parking space), the signal light 51 flashes red, which means that a car is about to park in or the last car has just left and the parking lock is about to lock the parking space. At this time, the signal light 51 flashes red, indicating that the parking cannot be stopped at this time, and parking may easily damage the vehicle;

[0080] Working state four: when the lock arm 12 is completely closed and there is no vehicle above the vehicle exit, the vehicle photographed by the camera 50 changes from large to small, and the height detected by the ultrasonic rangefinder changes from small to large. At this time, the signal light 51 changes from a green light to a flashing red light. When the parking lock is fully opened, it changes to a red light, indicating that the parking is not allowed at this time, because the previous car has just left. If the parking is done now, the information of the next car cannot be collected;

[0081] Working state five: when the locking arm 12 is fully closed and the vehicle enters the parking lot, the vehicle captured by the camera 50 changes from small to large, and the height detected by the ultrasonic rangefinder changes from large to small. At this time, the signal light 51 flashes green, indicating that the driver can park safely and can continuously adjust the position of the vehicle while parking, and no time-based charges will be generated.

[0082] Different working modes of the signal light 41 correspond to different states of the parking lock, so as to avoid collision when the driver cannot see the state of the ground lock due to the hood when the front of the vehicle enters the parking space. At this time, the driver can just look at the signal light 51 in the rearview mirror. In addition, different drivers have different driving skills and the time for reversing is also different. As long as the vehicle is not parked in the parking space, the green light will keep flashing and the vehicle will not be timed, so as to avoid extra charges for the vehicle.

[0083] When the driver is backing into a parking space, he no longer needs to observe the state of the parking lock, but only needs to see the flashing state of the signal light 51 above through the rearview mirror, so as to avoid collision accidents caused by the driver not being able to see the state of the ground lock due to the hood blocking the front of the vehicle when entering the parking space.

[0084] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with the technology to understand the content of the present invention and implement it accordingly, and they cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the protection scope of the present invention.
