[0002] A parking lock is a mechanical / electronic device installed on the ground or in a parking space, primarily used to prevent others from occupying a specific parking space.

[0003] Existing parking space locks generally have a lock box embedded in the ground and a flap that can rotate and extend out of the ground. The flap is driven to rotate by a screw drive assembly, which in turn causes the flap to flip, thereby locking and unlocking the parking space lock.

[0004] However, existing parking locks have high torque requirements for the screw drive assembly, resulting in a large drive assembly size. This, in turn, makes the overall size of the parking lock larger, increasing the degree of ground damage and making installation inconvenient. Utility Model Content

[0005] The purpose of this utility model is to provide an underground parking lock to solve the technical problems of existing parking locks having high torque requirements for the screw drive assembly and large drive assembly size, which leads to large overall size and inconvenient installation of the parking lock.

[0030] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] like Figure 1 As shown, this utility model embodiment provides an underground parking lock, including a housing 100, a flap 200, and a driving device. The housing 100 is used for underground installation and has an upward-opening receiving groove. One side of the flap 200 is hinged to the receiving groove so that the flap 200 can rotate around a first horizontal direction. The driving device is disposed in the receiving groove. The driving device includes a lead screw drive assembly 310, a drive link 320, and an auxiliary tension spring 330. The lead screw drive assembly 310 is disposed in the receiving groove along a second horizontal direction. One end of the drive link 320 is connected to the lead screw drive assembly 310 so as to move along the second horizontal direction with the lead screw drive assembly 310. The other end of the drive link 320 is hinged to the middle of the flap 200. One end of the auxiliary tension spring 330 is connected to the flap 200, and the other end of the auxiliary tension spring 330 is connected to the housing 100. The first horizontal direction and the second horizontal direction are perpendicular to each other.

[0032] That is, the underground parking lock provided by this utility model embodiment reduces the strength requirement of the screw by setting the screw drive device perpendicular to the rotation direction of the flap 200. At the same time, the auxiliary tension spring 330 reduces the power consumption of the motor and the volume of the drive device by counterweighting the flap 200, thus saving structural space. This solves the technical problem in the prior art that the parking lock has a high torque requirement for the screw drive assembly 310 and a large size of the drive assembly, which leads to a large overall size of the parking lock and inconvenient installation.

[0033] Specifically, in this embodiment, the box body 100 is generally rectangular, with edges around its perimeter for easy installation on the ground. The receiving slot, with its opening facing upwards, is also rectangular, with the first horizontal direction being the length direction of the receiving slot and the second horizontal direction being the width direction. A rotating shaft is provided on one side of the receiving slot, and one side of the flap 200 is rotatably mounted on the rotating shaft. The size of the flap 200 is the same as the size of the receiving slot, allowing the flap 200 to rotate around the rotating shaft, extending into the receiving slot to block vehicles from entering the parking space, or retracting into the receiving slot to open the parking space. The lead screw drive assembly 310 includes a drive motor, a lead screw, a nut, and a guide groove. The lead screw is connected to the drive motor via a coupling, the guide groove and the lead screw are arranged along the width direction of the receiving slot, and the nut is slidably mounted in the guide groove via a sliding groove. One end of the transmission connecting rod is hinged to the middle of the flap 200, and the other end is hinged to the nut. This allows the drive motor to rotate the lead screw, which in turn drives the nut to pull the transmission connecting rod, causing it to flip and rotate. Since the flap 200 rotates in a first horizontal direction and the lead screw is positioned in a second horizontal direction, the movement directions of the lead screw and drive connecting rod 320 are perpendicular to the rotation direction of the flap 200. This reduces the shear force on the lead screw after an impact, preventing the lead screw from bending. The auxiliary tension spring 330 is a metal spring, with one end installed in the receiving groove via a fixing plate, and the other end connected to the flap 200. When the flap 200 is fully open, the auxiliary tension spring 330 is in a free state; when the flap 200 is closed, the auxiliary tension spring 330 is in an extended state. This allows the auxiliary tension spring 330 to provide tension, reducing the force required to open the flap 200 and thus reducing the power required to drive the motor.

[0034] Furthermore, the drive device includes two auxiliary tension springs 330, the lead screw drive assembly 310 is disposed in the middle of the receiving groove, and the two auxiliary tension springs 330 are respectively disposed on both sides of the lead screw drive assembly 310.

[0035] Specifically, the lead screw drive assembly 310 is located in the middle of the receiving groove, and two auxiliary tension springs 330 are symmetrically arranged on both sides of the lead screw drive assembly 310. By adopting a central drive, the torque requirement of the spindle can be reduced.

[0036] Preferably, the flap 200 is provided with a tension spring arm 210, one end of which is fixed to the hinge side of the flap 200, and the other end of which is connected to the auxiliary tension spring 330. The tension spring arm 210 and the flap 200 are arranged at an angle.

[0037] Specifically, in this embodiment, a sleeve is provided on one side of the flap 200, which can be fitted onto the rotating shaft, allowing the flap 200 to rotate around the sleeve as the rotation center. One end of the tension spring arm 210 is fixed to the sleeve, and the tension spring arm 210 is arranged perpendicular to the flap 200. A connecting hole is provided at the other end of the tension spring arm 210, which is connected to an auxiliary tension spring 330. Thus, when the flap 200 rotates, the tension spring arm 210 will rotate accordingly. The larger the opening angle of the flap 200, the smaller the degree to which the tension spring arm 210 stretches the auxiliary tension spring 330, and the smaller the tension of the auxiliary tension spring 330. This achieves the goal of reducing the power consumption of the drive motor in the lead screw drive assembly 310 through the auxiliary tension spring 330.

[0038] Furthermore, the flap 200 is provided with a movable pin 220 along the first horizontal direction, and the drive link 320 is hinged to the movable pin 220.

[0039] Specifically, multiple support beams are provided on the flap 200, each with mounting holes arranged linearly and extending parallel to the first horizontal direction. A movable pin 220 passes through the mounting holes and is mounted on the support beam. A drive link 320 is hinged to the movable pin 220 to rotate around it. In the event of a drive mechanism malfunction, the flap 200 can be quickly lowered by pulling out the movable pin 220.

[0040] Furthermore, the side wall of the flap 200 is provided with anti-scratch strips 230.

[0041] Specifically, in this embodiment, anti-scratch strips 230 are provided on the flap 200 and the three side walls, and are made of rubber material, thereby reducing the damage caused by people and vehicles scraping against the flap 200.

[0042] Furthermore, the underground parking lock also includes a vehicle sensor, which is installed on the housing 100 and is used to detect vehicles near the underground parking lock.

[0043] Specifically, the vehicle sensing element is set as an infrared sensor, which can detect whether there is a nearby vehicle in the underground parking space lock. It is installed on the box 100 by bolts and provides a signal for the opening or closing of the flip panel 200.

[0044] Furthermore, the underground parking lock also includes an alarm 130 and a human body sensor. The human body sensor is installed in the housing 100, the alarm 130 is installed in the housing 100, and the human body sensor is connected to the alarm 130.

[0045] Specifically, the alarm 130 is a buzzer, and the human body sensor is an infrared sensor, both fixed to the housing 100 with bolts. The human body sensor can detect whether there is a human body near the flip panel 200, while the buzzer is connected to the human body sensor via a wire. After the human body sensor detects a human body, it sends a signal to the buzzer, thereby preventing people from tripping over the flip panel 200.

[0046] Furthermore, the underground parking lock also includes a solar charging panel 150, which is mounted on the housing 100.

[0047] Specifically, the solar charging panel 150 is disposed on the upper surface of the housing 100 and connected to the battery inside the housing 100, and the solar panel supplies power to the battery, thereby ensuring the operation of the parking lock. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
