Description

Technical Field

[0002] An in-ground parking lock is an anti-occupancy device installed in a parking space. It controls parking by burying the housing underground and using a rotating flap. The flap has two states: raised and lowered. When the flap is raised, it can effectively prevent vehicles from passing over the parking lock; when the flap is lowered, its upper surface is flush with the ground, allowing vehicle wheels to safely drive over it.

[0003] Currently, technologies such as the ground-mounted parking lock disclosed in Chinese patent application number 202322463495.9 have described the structure and working principle of typical in-ground parking locks. However, in practical applications, the installation of in-ground parking locks faces significant challenges. Given that most parking lot surfaces consist of an upper asphalt layer and a lower concrete layer, the asphalt layer is relatively easy to excavate, but the concrete layer is hard and dense, making excavation extremely difficult. If the in-ground parking lock itself is thick, installation inevitably requires damaging the concrete layer, which not only significantly increases the construction difficulty but also significantly increases installation costs and time.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without inventive effort are within the protection scope of the present utility model.

[0020] Example 1:

[0021] The low-height underground parking lock provided in Embodiment 1 of this utility model, such as Figures 1 to 6As shown, the system includes a mounting housing 1, a flip-plate transmission mechanism 2, and a flip-plate 3. The mounting housing 1 has a receiving groove 11 with its opening facing upwards. The bottom of the receiving groove 11 is a mounting base plate 12. The surface of the mounting base plate 12 is horizontal. A receiving hole 121 is provided on the mounting base plate 12, with the hole axis perpendicular to the surface of the mounting base plate 12. The flip-plate transmission mechanism 2 includes a motor 21, a worm gear 22, a worm wheel 23, and an output drum 24. The housing of the motor 21 is fixed to the mounting base plate 12. An output gear 211 is fixed to the output shaft of the motor 21. A transmission gear 212 is rotatably fixed to the housing of the motor 21. The height of the shaft of the transmission gear 212 is lower than the height of the shaft of the output gear 211. The transmission gear 212 meshes with the output gear 211. A worm gear 212 is coaxially fixed to the transmission gear 212. 2; The worm 22 is located in the receiving hole 121; the worm wheel 23 is rotatably fixed in the receiving groove 11; the worm 22 and the worm wheel 23 are in transmission cooperation; the shaft height of the worm wheel 23 is lower than the shaft height of the output gear 211; the rotating drum 24 is coaxially fixed to the end of the worm wheel 23; the rotating drum 24 has an internal spline hole 241; the internal spline hole 241 is set away from the worm wheel 23; the rotating shaft end of the flap 3 has an external spline protrusion 31; the external spline protrusion 31 is provided with an external spline that matches the internal spline hole; the external spline is coaxial with the rotating shaft of the flap; the external spline protrusion 31 is detachably fixed in the internal spline hole 241 (the rotating drum 24 and the flap 3 are fixed by the detachable cooperation of the internal spline hole 241 and the external spline protrusion 31, which is a conventional setting for coaxial rotation in the prior art, and will not be described in detail here as a preferred solution of this embodiment).

[0022] Embodiment 1 of this utility model effectively solves the technical bottleneck of excessive vertical thickness in traditional underground parking locks through innovative transmission structure design. In the prior art, the core reason for the limited thickness of underground parking locks lies in the mutual constraint between the height of the motor shaft and the height of the flap shaft. When the flap is directly fixed to the motor shaft or via a worm gear transmission assembly (in some parking locks, this is to protect the motor 21 shaft in case of abnormal rotation of the flap 3. For example, when a vehicle forcibly drives over the raised flap 3, the flap 3 reverses and drives the motor 21 shaft to rotate; a transmission assembly is set between the motor 21 shaft and the flap 3, and the abnormal rotation at the transmission assembly replaces the abnormal rotation of the motor 21 shaft to protect the motor 21; this transmission assembly is exemplified by a worm gear transmission assembly), the height of the worm shaft is rigidly determined by the motor mounting position, forcing the worm gear and flap shaft to be positioned above or below the motor. This, in turn, leads to two typical problems:

[0023] When the worm gear is positioned above the worm: the space below the motor housing is ineffectively occupied, and additional support columns are required to maintain the horizontal position after the flap is laid flat, which increases the vertical dimension of the receiving slot.

[0024] When the worm gear is located below the worm: the top structure of the motor housing must be higher than the upper surface of the flip plate, and the motor also needs to be buried underground, thus increasing the vertical dimension requirements of the receiving slot.

[0025] This solution adopts a gear-worm gear composite transmission structure: the motor output shaft meshes with the transmission gear 212 through the output gear 211, transforming the high axis position of the motor into a flexibly adjustable transmission gear axis height. Since gear meshing only requires ensuring the pitch circle is tangent, the axis of rotation of the transmission gear 212 can be adjusted up and down according to spatial layout requirements, thereby driving the coaxially fixed worm 22 to achieve free configuration of axis height. Combined with the low-position installation design of the worm gear 23 and the output drum 24, the height of the flap shaft is completely freed from the limitation of the motor body height—both can be arranged in a reasonable area of ​​the receiving slot 11. The motor does not require an additional support platform, and there is no redundant support structure under the flap, fundamentally compressing the parking lock. Overall height; Since the flap transmission mechanism 2 is the core component that restricts the thickness of the underground parking lock, when the motor 21 transmits power to the transmission gear 212 through the output gear 211, the worm 22, which is coaxial with the transmission gear 212, can extend downward into the receiving hole 121 of the mounting base plate 12, so that the position of the worm axis is lower than the height of the output shaft of the motor 21; The main function of the receiving hole 121 is to embed a part of the structure of the worm 22 into the thickness range of the mounting base plate 12. Through vertical space reuse, the overall height of the flap transmission mechanism 2 is effectively reduced; In practical applications, this embodiment can significantly reduce the ground excavation depth by reducing the thickness of the underground parking lock, thereby improving installation efficiency and reducing costs.

[0026] The low-height underground parking lock provided in Embodiment 1 of this utility model reduces the overall height of the transmission mechanism through a gear-worm gear composite transmission structure, thereby reducing the burial depth of the installation housing and avoiding damage to the concrete layer. This solves the problems of high installation difficulty and high installation cost of underground parking locks in the prior art, and can reduce installation difficulty and cost.

[0027] As a preferred embodiment, in this embodiment, the flap transmission mechanism 2 further includes a worm gear protective shell 25; the worm gear protective shell 25 includes a protective shell body 251, a fixed shaft 252, and a bearing 253; the protective shell body 251 is fixed in the receiving groove 11; the protective shell body 251 has a cylindrical fixing hole; the fixed shaft 252 is fixed in the receiving groove 11; the fixed shaft 252 is coaxial with the fixing hole; the inner ring of the bearing 253 is fixed to the fixed shaft 252; a central hole 231 is provided at the axis of rotation of the worm gear 23; the outer ring of the bearing 253 is fixed to the inner wall of the central hole 231 of the worm gear 23; the bearing 253 is fixed in the fixing hole; a transmission hole 2512 is provided on the lower side of the protective shell body 251; the transmission hole 2512 communicates with the fixing hole; the teeth of the worm 22 can extend from the transmission hole 2512 to mesh with the teeth of the worm gear 23. The worm gear protective shell 25 protects the worm gear. Without a protective shell, the tooth surface of the worm gear 23 is easily contaminated by dust, leading to accelerated wear. The fixed shaft 252 serves as the rotational center shaft for the bearing 253 and the worm gear 23, transmitting the load to the mounting housing 1. The bearing 253 reduces the rotational frictional resistance of the worm gear 23. The center hole 231 has an interference fit with the outer ring of the bearing 253, achieving centering of the worm gear 23 and transmitting torque to the output drum 24. The transmission hole 2512 provides a meshing channel for the worm 22. In this embodiment, two bearings 253 are preferably used, and the worm gear 23 is fixed to the fixed shaft 252 by the two bearings 253, achieving a two-point support structure. The radial runout of the worm gear 23 is ≤0.05mm. The protective shell body 251 prevents the worm 22 from directly facing the outside of the mounting housing 1 directly below the receiving hole 121, preventing dust and debris from entering the meshing area.

[0028] In this embodiment, the flip-plate transmission mechanism 2 further includes a protective housing 26; the protective housing 26 includes a worm gear isolation plate 261; the worm gear isolation plate 261 is disposed within the receiving hole 121; the worm gear isolation plate 261 seals the receiving hole 121; the thickness of the worm gear isolation plate 261 is less than the thickness of the mounting base plate 12; the lower bottom surface of the worm gear isolation plate 261 is flush with the lower bottom surface of the mounting base plate 12. The function of the worm gear isolation plate 261 is to seal the receiving hole 121 to prevent groundwater and silt from entering the motor chamber; the thickness of the worm gear isolation plate 261 is less than the thickness of the mounting base plate 12, and a space is formed between the upper surface of the worm gear isolation plate 261 and the upper surface of the mounting base plate 12 to accommodate the worm 22, so that the lower side teeth of the worm 22 can be located in this space. This design realizes vertical space reuse and reduces the space occupied by the vertical part of the flip-plate transmission mechanism 2.
