Abstract
Description
Technical Field
[0001] This utility model belongs to the field of intelligent parking locks, and in particular relates to a positioning device for intelligent underground parking locks. Background Art
[0002] A smart parking lock is a device used to protect parking spaces. It is typically installed on or buried in the ground to prevent unauthorized vehicles from occupying specific parking spaces. Through intelligent technology, it automatically locks and unlocks the parking space, facilitating user management and use. A typical in-ground parking lock has a housing embedded in the ground. A flap is located at the top of the housing, touching the ground. An internal drive mechanism drives the flap to flip and lift, locking the parking space by rotating and lifting the flap. When the flap is flush with the ground, it is unlocked, allowing free passage; when the flap is raised, it is locked, preventing vehicle passage. Current in-ground parking locks typically use a motor as the drive mechanism. The motor drives a shaft, which in turn rotates the flap. Over time, the connection between the flap and the shaft can loosen, causing the flap to shift axially. This prevents the flap from accurately engaging with the top of the housing, resulting in the flap not being flush with the ground and affecting vehicle accessibility. Utility Model Content
[0003] In order to solve the problems in related technologies, this utility model provides a positioning device for intelligent underground vehicle locks that can limit the flap and prevent the flap from failing to accurately fasten to the housing.
[0004] The technical solution is as follows:
[0005] This utility model provides a positioning device for a smart underground vehicle lock. The positioning device is disposed between the bottom of the housing and the flip plate of the underground vehicle lock. The positioning device includes an upper support plate, a lower support plate, a positioning component, and a limiting component. The upper support plate is disposed on the lower surface of the flip plate, and a clearance groove is provided at the positioning end of the bottom of the upper support plate. The positioning component is disposed within the clearance groove. The lower support plate is disposed on the upper surface of the housing, and the limiting component is disposed at the positioning end of the top of the lower support plate. The positioning ends of the upper and lower support plates are vertically corresponding. The limiting component is configured to limit the positioning component in the axial direction of the flip plate's rotation.
[0006] The beneficial effect of this technical solution is that by limiting the upper limit of the rotation axis of the flap through the limiting component, the lateral displacement of the flap is controlled, thus preventing the flap from failing to accurately engage with the housing.
[0007] Further, the limiting component includes a first slider, a second slider, a first top plate, a second top plate, a first spring, and a second spring, wherein: the first top plate and the second top plate are respectively disposed on both sides of the positioning end of the lower support plate along the axial direction of the rotation of the flip plate; the first slider is connected to the side of the first top plate facing the second top plate by the first spring; the second slider is connected to the side of the second top plate facing the first top plate by the second spring; the first slider and the second slider are arranged opposite to each other; the side of the first slider facing the second top plate has a first inclined surface, and the side of the second slider facing the first top plate has a second inclined surface; the first slider and the second slider merge under the action of the first spring and the second spring, and a limiting groove is formed between the first inclined surface and the second inclined surface; the limiting groove is configured to limit the positioning component in the axial direction of the rotation of the flip plate.
[0008] The beneficial effect of this technical solution is that when the flap rotates downward, the positioning component moves downward and contacts the first and second inclined surfaces. The first and second springs provide a reaction force, allowing the offset positioning component to return to the middle position, thereby achieving the limiting of the flap.
[0009] Furthermore, the limiting assembly also includes a first push rod and a second push rod, the first slider is provided with a first limiting hole, and the second slider is provided with a second limiting hole, wherein: the first end of the first push rod is connected to the first top plate, the second end of the first push rod extends into the first limiting hole, and the first spring is sleeved on the first push rod; the first end of the first push rod is connected to the first top plate, the second end of the first push rod extends into the first limiting hole, and the first spring is sleeved on the first push rod.
[0010] Furthermore, guide blocks are provided at the bottom of both the first slider and the second slider, and a guide rail is provided at the positioning end of the lower support plate along the moving direction of the first slider and the second slider, and the guide block is slidably connected to the guide rail.

[0021] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.
[0022] A typical in-ground car lock consists of a housing 1 embedded in the ground. A flap 2 is located at the top of the housing 1, touching the ground. An internal drive mechanism drives the flap 2 to flip and lift, locking the parking space by rotating and lifting the flap 2. When the flap 2 is flush with the ground, it is in the unlocked state, allowing free passage for vehicles. When the flap 2 is raised, it is in the locked state, preventing vehicle passage. In existing in-ground car locks, the drive mechanism is generally a motor. The motor drives a rotating shaft, which in turn rotates the flap 2. After prolonged use, the connection between the flap 2 and the shaft may loosen, causing the flap 2 to shift axially. This prevents the flap 2 from accurately engaging with the top of the housing 1, resulting in the flap 2 not being flush with the ground and affecting vehicle accessibility.
[0023] To solve the above-mentioned technical problems, this utility model provides a positioning device for intelligent underground vehicle locks that can limit the flap 2 and prevent the flap 2 from failing to accurately engage with the housing 1.
[0024] like Figure 1-3 As shown:
[0025] This utility model provides a positioning device for a smart underground vehicle lock. The positioning device is located between the bottom of the housing 1 and the flip plate 2 of the underground vehicle lock. The positioning device includes an upper support plate 3, a lower support plate 4, a positioning component 31, and a limiting component 5. The upper support plate 3 is located on the lower surface of the flip plate 2, and a clearance groove 32 is provided at the bottom positioning end of the upper support plate 3. The positioning component 31 is located within the clearance groove 32. The lower support plate 4 is located on the upper surface of the housing 1, and the limiting component 5 is located at the top positioning end of the lower support plate 4. The positioning ends of the upper support plate 3 and the lower support plate 4 are vertically corresponding. The limiting component 5 is configured to limit the positioning component 31 in the axial direction of the flip plate 2's rotation. When the flip plate 2 rotates and engages with the housing 1, the upper support plate 3 and the lower support plate 4 provide support, that is, they support the weight of the vehicle above between the bottom of the housing 1 and the flip plate 2. After the flap 2 is engaged, the positioning component 31 is limited by the limiting component 5, preventing the flap 2 from shifting laterally, i.e., it will not shift along the rotation axis. By limiting the upper axis of rotation of the flap 2 through the limiting component 5, the lateral displacement of the flap 2 is controlled, preventing the flap 2 from failing to engage accurately with the housing 1.
[0026] In one possible embodiment, the limiting component 5 includes a first slider 51, a second slider 52, a first top plate 53, a second top plate 54, a first spring 55, and a second spring 56, wherein: the first top plate 53 and the second top plate 54 are respectively disposed on both sides of the positioning end of the lower support plate 4 along the axial direction of rotation of the flip plate 2; the first slider 51 is connected to the side of the first top plate 53 facing the second top plate 54 by the first spring 55; the second slider 52 is connected to the side of the second top plate 54 facing the first top plate 53 by the second spring 56; the first slider 51 and the second slider 52 are arranged opposite to each other; the side of the first slider 51 facing the second top plate 54 is provided with a first inclined surface 517, and the side of the second slider 52 facing the first top plate 53 is provided with a second inclined surface 518; the first slider 51 and the second slider 52 merge under the action of the first spring 55 and the second spring 56, and a limiting groove is formed between the first inclined surface 517 and the second inclined surface 518; the limiting groove is configured to limit the positioning component 31 in the axial direction of rotation of the flip plate 2. When the flap 2 rotates downwards, the positioning component 31 moves downwards accordingly and contacts the first inclined surface 517 and the second inclined surface 518. The first spring 55 and the second spring 56 provide a reaction force, allowing the offset positioning component 31 to return to the center position, thus limiting the flap 2. The first spring 55 and the second spring 56 prevent the positioning component 31 from making hard contact with the first slider 51 and the second slider 52, avoiding damage to the component caused by the offset positioning component 31 forcibly entering the limiting groove. This structure allows the flap 2 to offset within a certain range without affecting the flatness of the fastening, ensuring normal fastening while preventing damage to the component.
[0027] In one possible embodiment, the limiting component 5 further includes a first push rod 511 and a second push rod 512. The first slider 51 is provided with a first limiting hole 513, and the second slider 52 is provided with a second limiting hole. Specifically, the first end of the first push rod 511 is connected to the first top plate 53, and the second end of the first push rod 511 extends into the first limiting hole 513. The first spring 55 is sleeved on the first push rod 511. The first push rod 511 and the second push rod 512 can limit the offset of the positioning component 31. When the offset of the positioning component 31 reaches the maximum compression set by the first spring 55 or the second spring 56, the first push rod 511 or the second push rod 512 will touch the bottom within the first limiting hole 513 or the second limiting hole, achieving the effect of limiting the positioning component 31. This structure can limit the flap 2 when the offset of the flap 2 is too large and the spring force alone cannot limit the flap 2.
[0028] In one possible embodiment, guide blocks 515 are provided at the bottom of both the first slider 51 and the second slider 52. A guide rail 516 is provided at the positioning end of the lower support plate 4 along the moving direction of the first slider 51 and the second slider 52. The guide blocks 515 are slidably connected to the guide rail 516. The guide blocks 515 at the bottom of the sliders, moving within the guide rail, can control the direction of slider movement, preventing the sliders from shifting and thus reducing the limiting effect.
