Description

Technical Field

[0001] The present invention relates to a ground lock and a ground lock system. Background Art

[0002] A ground lock, that is, a parking space lock, is a mechanical device that prevents others from occupying one's own car parking space, allowing one's own car to park at any time; however, existing ground locks can only be laid down backward. When the driver operates improperly and the car hits the ground lock, or when the ground lock fails to recognize the vehicle and the driver does not notice, the car can only hit the ground lock from the front to make the ground lock fall down, which will not damage the car. However, there are significant differences in everyone's driving skills, and when operating improperly, more often it hits the ground lock at a small angle from the side. At this time, the ground lock cannot be laid down backward, which will cause both the car and the ground lock to be damaged; therefore, there is an urgent need for a ground lock and a ground lock system to solve the above problems.

For example, they can be directly connected or indirectly connected through an intermediate medium; they can be fixedly connected, detachably connected, or integrally formed; they can be mechanically connected; they can be the communication inside two components or the interaction relationship between two components. Those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0026] Referring to Figures 1 to 4 , the ground lock includes:

[0027] A base 10, which can be installed underground;

[0028] ​The blocking member 20 is arranged on the base 10 through a rotating structure. The blocking member 20 can rotate along the X plane and the Y plane so that the blocking member 20 turns to the impact direction and tilts back to the impact direction when it is impacted.

[0029] The rotating structure includes a rotating base 30, an X-plane rotating assembly 40 and a Y-plane rotating assembly 50. The blocking member 20 is set on the rotating base 30 through the X-plane rotating assembly 40, and the rotating base 30 is set on the base 10 through the Y-plane rotating assembly 50. The Y-plane rotating assembly 50 can drive the blocking member 20, the rotating base 30 and the X-plane rotating assembly 40 to rotate in the Y plane, and the X-plane rotating assembly 40 can drive the blocking member 20 to rotate in the X plane.

[0030] As a preferred embodiment of the X-plane rotating assembly 40, the X-plane rotating assembly 40 includes a first gear 41, a connecting rod 42 and a first motor 43. The connecting rod 42 is rotatably passed through the rotating base 30 and its two ends are respectively connected to the first gear 41 and the blocking member 20. The first motor 43 is arranged on the rotating base 30 and its output end is provided with a second gear 44 that meshes with the first gear 41.

[0031] A torque converter mechanism 60 is further provided between the first gear 41 and the first motor 43 for reducing the torque transmitted to the first motor 43 via the first gear 41 .

[0032] The torque-changing mechanism 60 includes a worm 61 rotatably arranged on the rotating base 30 and a third gear 62 arranged on the worm 61. The worm 61 is engaged with the first gear 41, and the third gear 62 is engaged with the second gear 44. The number of teeth of the third gear 62 is greater than the number of teeth of the second gear 44. By adjusting the gear ratio between the third gear 62 and the second gear 44, the torque transmitted to the first motor 43 can be reduced to avoid damage to the first motor 43.

[0033] The blocking member 20 is connected to the connecting rod 42 via a connecting structure 70 .

[0034] The connecting structure 70 includes a connecting seat 71 and a cover plate 72 connected to the connecting seat 71 through a detachable structure 73. The connecting seat 71 is connected to the connecting rod 42. There is a space between the cover plate 72 and the connecting seat 71 for the blocking member 20 to pass through. A limiting structure 74 is set between the blocking member 20 and the connecting seat 71 and / or the cover plate 72 for limiting the relative movement between the blocking member 20 and the connecting seat 71.

[0035] As a preferred embodiment of the Y-plane rotation assembly 50, the Y-plane rotation assembly 50 includes a first rotating shaft, a second rotating shaft, and a second motor 51 disposed on the base 10. One end of the first rotating shaft is rotatably disposed on one side of the base 10, and the other end of the first rotating shaft is connected to one side of the rotating seat 30. One end of the second rotating shaft is connected to the other side of the rotating seat 30, and the other end of the second rotating shaft is rotatably disposed on the other side of the base 10 and connected to the output end of the second motor 51. In order to ensure that when a vehicle hits the ground lock, the blocking member 20 will deflect towards the impact direction of the vehicle, the static torque of the second motor 51 can be made less than the static torque of the first motor 43. At this time, when the blocking member 20 is impacted, it will first deflect and then topple, that is, it will first rotate in the X-plane and then rotate in the Y-plane.

[0036] The ground lock system includes a controller 81, an identification module 82, and the ground lock described above. The controller 81 is electrically connected to the ground lock and the identification module 82. The identification module 82 is used to identify whether the vehicle is legal. If it is legal, the controller 81 sends an instruction to the rotating structure to control the blocking member 20 to topple along the Y-plane; if it is not legal, there is no action.

[0037] The identification module 82 is set as a Bluetooth module, an NFC module, an RFID module, or a mobile communication module. When the identification module 82 is a Bluetooth module, the vehicle is connected and matched with the identification module 82, and only the vehicle that is connected and verified can activate the ground lock. When the identification module is an NFC module, only the vehicle with a legal NFC key can activate the ground lock. When the identification module 82 is an RFID module, only the vehicle with a legal RFID tag can activate the ground lock. When the identification module 82 is a mobile communication module, such as a 4G or 5G module, the vehicle can be verified through the Internet, such as through a mini-program, an APP, or by scanning a code on-site, to activate the ground lock. Of course, it can also be other methods, which will not be elaborated here. All the above embodiments of the identification module 82 can use existing technologies without technical obstacles.

[0038] In the present invention, its working principle is as follows:

[0039] 1. When the ground lock is in normal use and the vehicle is parked in the parking space normally, the recognition module 82 in the ground lock system is used to identify whether the vehicle is an authorized vehicle. The recognition module 82 can be a Bluetooth module. Specifically, the ground lock is bound to the vehicle by means of Bluetooth matching. When the verified vehicle approaches the ground lock, it will match and connect with the ground lock. After passing the verification, the recognition module 82 sends a control instruction to the rotating structure by the controller 81. The rotating structure is preferably an X-plane rotating assembly 40 with a first motor 43 and a Y-plane rotating assembly 50 with a second motor 51. At this time, the length direction of the blocking member 20 faces the parking space. The second motor 51 will start and drive the rotating seat 30, the blocking member 20 and the X-plane rotating assembly 40 to rotate in the Y plane. The blocking member 20 will fall backward, allowing the vehicle to park in the parking space. When the vehicle leaves the parking space, if the recognition module 82 detects that the vehicle is not in the parking space or the recognition module 82 is disconnected from the vehicle, a control instruction is sent to the rotating structure through the controller 81 to reset the blocking member 20. It should be noted that the first motor 43 and the second motor 51 are always in an unpowered state before receiving the action command.

[0040] 2. When the ground lock is in normal use and the recognition module 82 in the ground lock system identifies that the vehicle is an authorized vehicle, but when the vehicle hits the ground lock due to improper operation, when the vehicle hits the blocking member 20 and continues to move forward, the blocking member 20 will deflect in the direction of the impact. The deflection will drive the first gear 41 to rotate, and sequentially drive the worm 61, the third gear 62 and the second gear 44 to rotate. Since the first motor 43 and the second motor 51 are always in an unpowered state before receiving the action command, until the torque of the second gear 44 rotation is greater than the static torque of the first motor 43, the rotating shaft of the first motor 43 will rotate at this time, thus completing the deflection of the blocking member 20, making the blocking member 20 face the direction of the vehicle impact. Further, when the vehicle continues to move forward, a greater force will be exerted on the blocking member 20 until it exceeds the static torque of the second motor 51, which will drive the rotating shaft of the second motor 51 to rotate. At this time, the blocking member 20, the rotating seat 30 and the X-plane rotating assembly 40 will rotate as a whole. Specifically, they will rotate as a whole in the direction away from the vehicle impact, so that the blocking member 30 will not cause serious damage to the vehicle or damage the ground lock. When the danger of the vehicle is lifted, the ground lock can be automatically reset or reset manually by the user.

[0041] 3. When the ground lock is in normal use and the recognition module 82 in the ground lock system identifies that the vehicle is an illegal vehicle, its action process is the same as that in the above point 2 and will not be elaborated here. However, an alarm signal will be issued at this time to inform the backstage management personnel that an illegal vehicle has parked in the parking space forcefully and come to deal with it in time.

[0042] 4. The X-axis and Y-axis in the present invention are defined with reference to the normal use of the blocking member 30. When the angle of the blocking member 30 changes, the X-axis remains unchanged while the Y-axis will vary, which is obvious and should not be considered unclear.

[0043] Certainly, the present invention is not limited to the above embodiments. Those skilled in the art can make equivalent deformations or substitutions without departing from the spirit of the present invention, and these equivalent deformations and substitutions are all included within the scope defined by the claims of this application.
