Description

Technical Field

[0001] This utility model relates to the field of parking space locks, and in particular to an underground parking space lock with a retractable flap. Background Technology

[0002] An underground parking space lock is a parking space occupancy control device buried underground in the parking space. Its core structure usually includes an underground box, a rotatable flap, a drive mechanism, and a rotating shaft. The underground box is fixed in the pre-set pit of the parking space. The drive mechanism drives the rotating shaft to rotate, which in turn drives the flap fixed on the rotating shaft to rotate. When the upper side of the flap is flush with the ground, it does not affect the normal passage of vehicles. When the upper side of the flap is in a vertical or tilted state, it will form a blocking structure to prevent vehicles from entering the parking space. For example, Chinese patent application number 202322881409.6 discloses a ground-mounted smart parking lock, which discloses the specific structure and working principle of an underground parking lock.

[0003] However, to achieve an effective vehicle-blocking height, existing flappers must be designed with a correspondingly high platform height. This results in the flap occupying the same width across the parking space when lying down as it does when standing up. This necessitates excavating a wider pit during installation, which not only damages the ground area and increases construction difficulty, but also forces the flap to bear the entire weight of the wheel when it's lying down, potentially causing deformation over time. Conversely, reducing the flap height results in insufficient height when standing up to effectively block vehicles. According to the lever principle, the resistance torque when the flap is standing up is directly proportional to the flap's height, i.e., the lever arm length. Existing fixed-height flaps have a longer lever arm at the end furthest from the pivot, requiring the drive mechanism to overcome a greater torque to rotate the flap. This necessitates the use of high-power drive motors and high-strength transmission components, increasing both manufacturing costs and energy consumption. Utility Model Content

[0004] To address the aforementioned technical problems, the underground parking space lock with a retractable flap provided by this utility model can reduce the deformation of the flap due to pressure and reduce the power required for flap rotation.

When the rotating shaft rotates, the outer flip-type plate can be rotated until its upper side is flush with the opening of the receiving groove, and the blocking side can extend beyond the opening of the receiving groove. A second cavity is provided inside the outer flip-type plate. The blocking side has an extension opening communicating with the second cavity. The inner flip-type plate is slidably fixed within the second cavity. The inner flip-type plate can extend from the extension opening to the outside of the second cavity.

Like reference numerals denote like parts throughout the drawings. The drawings are not intentionally drawn to scale; the focus is on illustrating the gist of the invention.

[0012] Figure 2 This is a schematic diagram of the drive mechanism of the retractable flip-type underground parking space lock provided in Embodiment 1 of this utility model. Detailed Implementation

[0013] Example 1: The retractable flip-type underground parking space lock provided in Embodiment 1 of this utility model, such as Figures 1 to 2As shown, the device includes a buried enclosure 1, a rotating shaft 2, a drive mechanism 3, an outer flap 4, and an inner flap 5. The buried enclosure 1 includes a receiving groove 11. The rotating shaft 2 is rotatably fixed within the receiving groove 11. The outer flap 4 includes a connecting side 41 and a blocking side 42 arranged opposite to each other. The connecting side 41 is fixed to the rotating shaft 2. When the rotating shaft 2 rotates, the outer flap 4 can be rotated until its upper side is flush with the opening of the receiving groove 11, and the blocking side 42 can extend beyond the opening of the receiving groove 11. A second cavity is provided inside the outer flap 4. The blocking side 42 is provided with an extension opening 421 that connects to the second cavity. The inner flap 5 is slidably fixed within the second cavity. The inner flap 5 can extend from the extension opening 421 to the outside of the second cavity. The drive mechanism is fixed within the receiving groove 11. The drive mechanism can drive the inner flap 5 to slide within the second cavity.

[0014] The retractable flip-plate underground parking space lock provided in Embodiment 1 of this utility model has a passage mode and an obstruction mode when in operation. The receiving groove 11 of the underground housing 1 is buried in the pre-set pit of the parking space, and the rotating shaft 2 is rotatably fixed in the receiving groove 11. The connecting side 41 of the outer flip plate 4 is fixed to the rotating shaft 2. In the passage mode, the upper side of the outer flip plate 4 is flush with the opening of the receiving groove 11, and the inner flip plate 5 is completely housed in the second cavity of the outer flip plate 4, not protruding from the ground, allowing vehicles to pass normally. In the obstruction mode, the rotating shaft... 2. When the outer flap 4 is rotated, since the connecting side 41 of the outer flap 4 is fixed to the rotating shaft 2, the rotating shaft 2 drives the outer flap 4 to rotate synchronously, so that the blocking side 42 of the outer flap 4 gradually extends out of the opening of the receiving groove 11 and leaves the horizontal passage position. Then the drive mechanism 3 continues to operate, driving the inner flap 5 to move in the sliding direction in the second cavity. The inner flap 5 extends from the extension 421 of the blocking side 42 to the outside of the second cavity, and together with the outer flap 4, forms a blocking structure with sufficient height to prevent the vehicle from driving into the parking space. Compared with existing technologies, since the flap is a combination design of an outer flap 4 and an inner flap 5, the required height of the outer flap is smaller than that of a conventional flap. It eliminates the need to design the outer flap 4 as a tall plate to achieve effective blocking height. Because the outer flap 4 occupies the same width as its own height in the parking space when horizontal, there is no need to expand the width of the receiving slot 11, reducing the excavation area and construction difficulty. When a wheel rolls over the surface, most of the load is borne by the parking space ground, and the outer flap 4 only bears a portion of the distributed load, avoiding the problem of existing fixed high flaps directly bearing the entire weight of the wheel and reducing deformation of the outer flap 4. According to the lever principle, the height of the outer flap 4 directly determines the lever arm length when the rotating shaft 2 rotates. In this embodiment, the height of the outer flap 4 is reduced, resulting in a smaller resistance torque when the rotating shaft 2 drives the outer flap 4 to flip. The drive mechanism 3 can be easily driven without high-power output components.

[0015] The retractable flap underground parking lock provided in Embodiment 1 of this utility model solves the problem that the flap of the underground parking lock is easily deformed when squeezed by wheels in the prior art, and can reduce the deformation of the flap due to pressure.

[0016] As a preferred embodiment, in this embodiment, the drive mechanism 3 includes a driving bevel gear 31, a driven bevel gear 32, a threaded rod 33, and a ball nut 34; the driving bevel gear 31 is coaxially fixed on the rotating shaft 2; the driven bevel gear 32 is coaxially fixed on the threaded rod 33; the driving bevel gear and the driven bevel gear are connected in a transmission manner; the threaded rod 33 is rotatably fixed on the outer flap 4; the extension direction of the threaded rod 33 is consistent with the sliding direction of the inner flap 5; the inner ring of the ball nut 34 is engaged with the threaded rod 33; the outer ring of the ball nut 34 is connected to the inner flap 5. When the rotating shaft 2 rotates around its own axis, since the driving bevel gear 31 is coaxially fixed on the rotating shaft 2, the rotating shaft 2 synchronously drives the driving bevel gear 31 to rotate. The driving bevel gear 31 meshes with the driven bevel gear 32, and by utilizing the meshing characteristics of bevel gears, the horizontal rotational motion of the rotating shaft 2 is converted into the vertical rotational motion of the driven bevel gear 32. The driven bevel gear 32 is coaxially fixed on the threaded rod 33, and its rotation drives the threaded rod 33 to rotate synchronously. The inner ring of the ball nut 34 and the threaded rod 33 are connected by ball bearings. The outer ring is fixedly connected to the inner flap 5, and the inner flap 5 is constrained by the second cavity of the outer flap 4. The inner flap 5 can only slide in the extension direction, so the ball nut 34 cannot rotate synchronously with the threaded rod 33, but can only move linearly in the extension direction of the threaded rod 33. When the rotating shaft 2 drives the outer flap 4 to flip upward, the threaded rod 33 rotates in the forward direction, pushing the ball nut 34 to drive the inner flap 5 to slide along the second cavity towards the protrusion 421. Finally, the inner flap 5 protrudes from the protrusion 421. Therefore, in this embodiment, only the rotational power of the rotating shaft 2 is used to drive the flipping of the outer flap 4 and the extension of the inner flap 5.

[0017] In the passage mode, the inner flap 5 needs to be completely retracted into the second cavity of the outer flap 4. If there is no gap between the protruding end 51 and the protrusion 421, then when it is necessary to switch to the blocking mode, the extension of the inner flap 5 and the rotation of the outer flap 4 are carried out synchronously. The inner flap 5 may hit the side wall of the receiving groove 11 and hinder the rotation of the outer flap 4. To solve this problem, in this embodiment, the inner flap 5 includes a protruding end 51; the protruding end 51 faces the protrusion 421; when the upper side of the outer flap 4 is flush with the opening of the receiving groove 11, the protruding end 51 is spaced from the protrusion 421; when the lower end of the protrusion 421 is flush with the opening of the receiving groove 11, the protruding end 51 is flush with the protrusion 421. Since there is a gap between the protruding end 51 and the protruding opening 421 in the passage state, although the inner flap 5 will move synchronously with the outer flap 4, the inner flap 5 will always be in the second cavity at the beginning and will not protrude from the second cavity, so it will not affect the normal rotation of the outer flap 4.

[0018] In this embodiment, a rubber washer is provided at the protruding end 51 of the inner flap 5. The rubber washer, through its own flexible deformation, reduces the damage to the wheels caused by the inner flap 5 when the vehicle recklessly drives over the second flap 5 which is in an obstructive state.
