Description

Technical Field

[0001] This utility model relates to the field of floor locks, and in particular to an anti-impact smart floor lock. Background Technology

[0002] Smart parking locks are mechanical devices used to prevent vehicles from occupying parking spaces.

[0003] The structure of a smart floor lock can be referenced from a patent with Chinese patent application number 201520827104.X, which discloses a pneumatic anti-crushing assist floor lock that can display a license plate number. It includes a base, a gas spring, and a baffle. Each side of the baffle has a leg, and each leg is hinged to a base. The base has multiple bolt holes, and a gas spring is obliquely connected between each leg and the corresponding side of the base. The above patent uses a gas spring to support the baffle. Furthermore, the gas spring can assist in manually lifting the baffle, thereby reducing the labor cost required to lift the baffle.

[0004] However, when using the ground lock provided by the aforementioned patent, if the vehicle drives over the ground lock with the barrier raised, the vehicle's chassis will come into contact with the barrier. The gas spring will support the barrier, making it difficult for the barrier to fall down, which can easily damage the barrier and scratch the vehicle's chassis. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an anti-collision smart ground lock that solves the problem that existing technologies can damage the barrier and scratch the vehicle chassis when a vehicle forcibly passes through; it extends the service life of the ground lock barrier and prevents scratches on the vehicle chassis.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This utility model provides an anti-impact smart lock, including a rotating shaft, a drive mechanism, and a baffle; the rotating shaft is horizontally arranged; the drive mechanism drives the rotating shaft to rotate;

[0008] If the baffle is horizontally positioned, the top of the rotating shaft is cut to form a cross-sectional plane; the lower surface of the baffle is in contact with the cross-sectional plane; an iron block is embedded in the baffle; a magnet is embedded in the rotating shaft; the baffle and the rotating shaft are magnetically attracted to each other.

[0009] It also includes a limiting component; the limiting component includes two limiting plates; the limiting plates have through-holes; the rotating shaft is sleeved in the limiting holes; the rotating shaft and the limiting holes are rotatably fixed.

[0010] The baffle is located between the two limiting plates; the side of the two limiting plates adjacent to each other is taken as the inner side, and a first limiting groove and a second limiting groove are formed on the inner plate surface of the limiting plate;

[0011] With the extension direction of the rotating shaft as the left and right direction, the baffle is provided with limiting rods on the left and right sides; when the baffle is raised relative to the ground, the end of the baffle closer to the ground is taken as the near-ground end, and the end of the baffle farther from the ground is taken as the far-ground end, and the near-ground end of the baffle is in contact with the rotating shaft; the limiting rod is close to the near-ground end of the baffle;

[0012] Both the cross-section of the first limiting groove and the cross-section of the second limiting groove are arc-shaped. When the baffle is horizontally set, the far end of the baffle is taken as the front side and the near end of the baffle is taken as the rear side. The arcs of the first limiting groove and the second limiting groove both bulge rearward. The first limiting groove is located in front of the second limiting groove. The bottom ends of the first limiting groove and the second limiting groove coincide. The limiting rod slides within the first limiting groove and the second limiting groove.

[0013] When the baffle is set horizontally, the limiting rod is located at the top of the first limiting groove; when the baffle is raised, the limiting rod is located at the bottom of the first limiting groove and also at the bottom of the second limiting groove.

[0014] The impact-resistant smart lock provided by this utility model preferably has a spring in the second limiting groove; the spring is bent along the extension direction of the second limiting groove; one end of the spring is fixed to the top of the second limiting groove.

[0015] The anti-collision smart lock provided by this utility model preferably includes a limiting rod body and a cylinder; if the cylinder is vertically arranged, the cross-section of the cylinder is annular; the limiting rod body is sleeved inside the cylinder; the limiting rod body and the cylinder are rotatably fixed; when the limiting rod is located in the first limiting groove or the second limiting groove, the side wall of the cylinder is tightly attached to the inner wall of the first limiting groove or the inner wall of the second limiting groove.

[0016] The impact-resistant smart lock provided by this utility model preferably has an elastic element at the far end of the baffle.

[0017] The impact-resistant smart lock provided by this utility model preferably has a rounded outer end of the elastic element.

[0018] The impact-resistant smart lock provided by this utility model preferably has a rounded corner formed by the intersection of the cross-sectional plane and the outer wall of the rotating shaft.

[0019] The above technical solution has the following advantages or beneficial effects:

[0020] The anti-collision smart floor lock provided by this utility model includes a rotating shaft, a drive mechanism, and a baffle. Specifically, the rotating shaft is set horizontally so that the axis of the transmission shaft is parallel to the mounting base. The drive mechanism drives the rotating shaft to rotate. It should be noted that the rotating shaft rotates on its own axis rather than around an object, and is used to drive the baffle to rise and fall.

[0021] To facilitate the explanation of the connection between the baffle and the rotating shaft, it is assumed that: if the baffle is horizontally set, the top of the rotating shaft is cut to form a cross-sectional plane, which is used to fit the baffle. Specifically, the lower surface of the baffle is in contact with the cross-sectional plane, and an iron block is embedded in the baffle, while a magnet is embedded in the rotating shaft, so that the baffle and the rotating shaft are magnetically fixed together, allowing the baffle to rise and fall with the rotation of the rotating shaft. Furthermore, the magnetic fixation between the baffle and the rotating shaft allows the baffle to separate from the rotating shaft when subjected to a certain external force, thus preventing damage to the baffle or the rotating shaft due to rigid stress. At the same time, because the baffle and the rotating shaft are separated, the baffle cannot maintain a tilted raised state, thus preventing continuous contact with the vehicle chassis and avoiding scratches to the vehicle chassis. Moreover, the separation of the baffle from the rotating shaft can prevent the baffle from forcibly rotating the rotating shaft, which could damage the drive mechanism (motor).

[0022] When using magnetic attraction to fix the baffle and the rotating shaft, if the baffle separates from the rotating shaft, the baffle cannot be restored to the state of magnetic connection with the rotating shaft. Therefore, a limiting component is also included. Specifically, the limiting component includes two limiting plates, with limiting holes through the limiting plates. The rotating shaft is sleeved in the limiting holes, and the rotating shaft and the limiting holes are rotatably fixed. It should be noted that the rotating shaft and the limiting holes can be rotatably fixed using bearings, but the connection method will not be described in detail here. By rotatably fixing the rotating shaft and the limiting plates, the compressive force generated by the baffle when it is hit by a vehicle is distributed to the limiting plates, preventing the rotating shaft from being damaged by force.

[0023] Furthermore, since the rotating shaft and the two limiting plates are rotatably fixed, the baffle is located between the two limiting plates. Taking the adjacent side of the two limiting plates as the inner side, a first limiting groove and a second limiting groove are provided on the inner plate surface of the limiting plate. The second limiting groove is used to limit the direction of the baffle's movement under force, so that the baffle can return along its movement direction, thereby restoring the magnetic attraction between the baffle and the rotating shaft. Since the baffle needs to complete the lifting function, a first limiting groove is also provided to cooperate with the second limiting groove.

[0024] To limit the movement path of the baffle through the first and second limiting grooves, the extension direction of the rotation shaft is taken as the left and right direction. Limiting rods are provided on the left and right sides of the baffle, and the limiting rods are engaged in the first or second limiting groove. To facilitate the description of the positional relationship between the limiting rods and the limiting grooves, the definitions of near-ground end and far-ground end are introduced here. Specifically, when the baffle is raised relative to the ground, the end of the baffle closer to the ground is taken as the near-ground end, and the end of the baffle farther from the ground is taken as the far-ground end. The near-ground end of the baffle is in contact with the rotation shaft, and the limiting rod is close to the near-ground end of the baffle.

[0025] Because the baffle rotates around the axis of the rotating shaft as its centerline during lifting and lowering, the movement direction of the limiting rod is arc-shaped. Similarly, when the baffle is impacted by a vehicle, it rotates around the edge of the cross-section near the far end as the center of pressure, and the movement direction of the limiting rod is also arc-shaped. Therefore, the cross-sections of the first and second limiting grooves are both arc-shaped. Specifically, the positional relationship between the first and second limiting grooves is as follows: when the baffle is horizontally set, the far end of the baffle is taken as the front side, and the near end of the baffle is taken as the rear side. The arc of the first limiting groove... Both the first and second limiting grooves have arcs that bulge rearward, with the first limiting groove located in front of the second limiting groove. It can be understood that for the limiting rod to function, the bottom ends of the first and second limiting grooves must overlap (connect), allowing the limiting rod to slide within both grooves. When the baffle is horizontal, the limiting rod is at the top of the first limiting groove. When the baffle is raised, the limiting rod is at the bottom of both the first and second limiting grooves. When the baffle is impacted by a vehicle, the limiting rod moves along the extension direction of the second limiting groove.

[0026] Existing technologies can damage the barrier and scratch the vehicle chassis when a vehicle forcibly passes through it. To address this, the intelligent anti-collision ground lock provided by this invention uses magnetic attraction to fix the barrier and the rotating shaft. This allows the barrier to separate from the rotating shaft upon impact with a vehicle, preventing damage to either the barrier or the rotating shaft due to rigid stress. Furthermore, once separated, the barrier cannot maintain its tilted, raised state, thus preventing continuous contact with the vehicle chassis and avoiding scratches. By setting a limiting rod on the barrier, along with a first limiting groove and a second limiting groove on the limiting plate, the movement path of the barrier can be limited, allowing the barrier to return to its magnetically connected state with the rotating shaft.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0033] Example 1:

[0034] like Figures 1-2 and Figure 4 As shown, Embodiment 1 of this utility model provides an anti-collision smart lock, including a rotating shaft 1, a drive mechanism 2, and a baffle 3; the rotating shaft 1 is horizontally arranged; the drive mechanism 2 drives the rotating shaft 1 to rotate;

[0035] If the baffle 3 is set horizontally, the top of the rotating shaft 1 is cut to form a cross-sectional plane 11; the lower surface of the baffle 3 is in contact with the cross-sectional plane 11; an iron block is embedded in the baffle 3; a magnetic block is embedded in the rotating shaft 1; the baffle 3 and the rotating shaft 1 are magnetically attracted to each other.

[0036] It also includes a limiting component 4; the limiting component 4 includes two limiting plates 41; a limiting hole 411 is formed through the limiting plate 41; the rotating shaft 1 is sleeved in the limiting hole 411; the rotating shaft 1 and the limiting hole 411 are rotatably fixed.

[0037] The baffle 3 is located between two limiting plates 41; the adjacent side of the two limiting plates 41 is taken as the inner side, and the inner plate surface of the limiting plate 41 is provided with a first limiting groove 412 and a second limiting groove 413.

[0038] With the extension direction of the rotating shaft 1 as the left and right direction, the baffle 3 is provided with limiting rods 31 on the left and right sides; when the baffle 3 is raised relative to the ground, the end of the baffle 3 closest to the ground is taken as the near-ground end, and the end of the baffle 3 furthest from the ground is taken as the far-ground end, and the near-ground end of the baffle 3 is in contact with the rotating shaft 1; the limiting rods 31 are close to the near-ground end of the baffle 3.

[0039] The cross-sections of the first limiting groove 412 and the second limiting groove 413 are both arc-shaped. When the baffle 3 is horizontally set, the far end of the baffle 3 is taken as the front side and the near end of the baffle 3 is taken as the rear side. The arcs of the first limiting groove 412 and the second limiting groove 413 both protrude to the rear side. The first limiting groove 412 is located in front of the second limiting groove 413. The bottom end of the first limiting groove 412 and the bottom end of the second limiting groove 413 coincide. The limiting rod 31 slides within the first limiting groove 412 and the second limiting groove 413.

[0040] When the baffle 3 is set horizontally, the limiting rod 31 is located at the top of the first limiting groove 412; when the baffle 3 is lifted, the limiting rod 31 is located at the bottom of the first limiting groove 412 and also at the bottom of the second limiting groove 413.

[0041] When using the anti-collision smart parking lock provided in Embodiment 1 of this utility model, when a car is parked in the parking space, the baffle 3 is in a horizontal state, leaving space above for the vehicle to park; when no car is parked in the parking space, the drive mechanism 2 drives the rotating shaft 1 to rotate (the drive mechanism 2 here can be a motor directly driving the rotating shaft 1, or a motor driving a worm gear to rotate, and the worm gear driving a turbine connected to the rotating shaft 1), causing the baffle 3 to rise. The limiting rod 31 fixed to the baffle 3 moves from the top of the first limiting groove 412 along the extension direction (arc) of the first limiting groove 412 until the limiting rod 31 is in the raised state. At this time, the limiting rod 31 is located at the bottom of the first limiting groove 412, and the baffle 3 is in an inclined state, with the upper surface of the baffle 3 facing the direction of vehicle entry; when a vehicle forcibly passes through the raised baffle 3, the vehicle's chassis... When in contact with the far end of the baffle 3, the baffle 3 uses the edge of the cross-section 11 near the far end as the pressure center. Since the baffle 3 and the rotating shaft 1 are magnetically attracted, if the vehicle applies a force to the baffle 3 that exceeds the magnetic attraction force, the baffle 3 will separate from the rotating shaft 1. Then, due to the inertia of the force, the baffle 3 will rotate around the pressure center. At this time, the limiting rod 31 fixed to the baffle 3 moves from the bottom end of the second limiting groove 413 (the bottom end of the first limiting groove 412) along the extension direction (arc) of the second limiting groove 413, providing the baffle 3 with a force buffer space. After the vehicle passes, the limiting rod 31 returns to the bottom end of the second limiting groove 413 along the extension direction of the second limiting groove 413, and the baffle 3 and the rotating shaft 1 are re-attached and fixed. It should be noted that the above-mentioned ground lock structure can be encapsulated in the housing to resist component damage caused by natural erosion.

[0042] The anti-collision smart lock provided in Embodiment 1 of this utility model includes a rotating shaft 1, a drive mechanism 2, and a baffle 3. Specifically, the rotating shaft 1 is set horizontally so that the axis of the drive shaft 1 is parallel to the mounting base. The drive mechanism 2 drives the rotating shaft 1 to rotate. It should be noted that the rotating shaft 1 rotates around its own axis rather than around an object, and is used to drive the baffle 3 to rise and fall.

[0043] To facilitate the explanation of the connection relationship between the baffle 3 and the rotating shaft 1, it is assumed here that: if the baffle 3 is set horizontally, the top of the rotating shaft 1 is cut to form a cross-sectional plane 11, which is used to fit the baffle 3. Specifically, the lower surface of the baffle 3 is in contact with the cross-sectional plane 11, and an iron block is embedded in the baffle 3, while a magnet is embedded in the rotating shaft 1, so that the baffle 3 and the rotating shaft 1 are magnetically fixed together, allowing the baffle 3 to rise and fall with the rotation of the rotating shaft 1. Furthermore, the magnetic fixation between the baffle 3 and the rotating shaft 1 allows the baffle 3 to separate from the rotating shaft 1 when subjected to a certain external force, thereby preventing damage to the baffle 3 or the rotating shaft 1 due to rigid stress. At the same time, since the baffle 3 and the rotating shaft 1 are separated, the baffle 3 cannot maintain a tilted raised state, thus preventing continuous contact with the vehicle chassis and avoiding scratches to the vehicle chassis. Moreover, the separation of the baffle 3 from the rotating shaft 1 can prevent the baffle 3 from forcibly rotating the rotating shaft 1, which would damage the drive mechanism 2 (motor).

[0044] When the baffle 3 and the rotating shaft 1 are fixed by magnetic attraction, if the baffle 3 separates from the rotating shaft 1, the baffle 3 cannot be restored to the state of magnetic connection with the rotating shaft 1. Therefore, a limiting component 4 is also included. Specifically, the limiting component 4 includes two limiting plates 41, with limiting holes 411 extending through the limiting plates 41. The rotating shaft 1 is sleeved in the limiting holes 411, and the rotating shaft 1 is rotatably fixed to the limiting holes 411. It should be noted that the rotating shaft 1 and the limiting holes 411 can be rotatably fixed by bearings, but the connection method will not be described in detail here. By rotatably fixing the rotating shaft 1 to the limiting plates 41, the compressive force generated by the baffle 3 when it is hit by a vehicle is distributed to the limiting plates 41, preventing the rotating shaft 1 from being damaged by force.

[0045] Furthermore, since the rotating shaft 1 and the two limiting plates 41 are rotatably fixed, the baffle 3 is located between the two limiting plates 41. Taking the adjacent side of the two limiting plates 41 as the inner side, a first limiting groove 412 and a second limiting groove 413 are provided on the inner plate surface of the limiting plate 41. The second limiting groove 413 is used to limit the direction of movement of the baffle 3 under force, so that the baffle 3 can return along its movement direction, thereby restoring the magnetic attraction between the baffle 3 and the rotating shaft 1. Since the baffle 3 needs to complete the lifting function, a first limiting groove 412 is also provided to cooperate with the second limiting groove 413.

[0046] In order to limit the movement path of the baffle 3 through the first limiting groove 412 and the second limiting groove 413, the extension direction of the rotating shaft 1 is taken as the left and right direction. Limiting rods 31 are provided on the left and right sides of the baffle 3. The limiting rods 31 are inserted into the first limiting groove 412 or the second limiting groove 413. In order to facilitate the description of the positional structural relationship between the limiting rods 31 and the limiting grooves, the definitions of near-ground end and far-ground end are introduced here. Specifically, when the baffle 3 is raised relative to the ground, the end of the baffle 3 that is close to the ground is taken as the near-ground end, and the end of the baffle 3 that is far from the ground is taken as the far-ground end. The near-ground end of the baffle 3 is in contact with the rotating shaft 1, and the limiting rods 31 are close to the near-ground end of the baffle 3.

[0047] Because the baffle 3 rotates around the axis of the rotating shaft 1 as its centerline during lifting and lowering, the movement direction of the limiting rod 31 is arc-shaped. Similarly, when the baffle 3 is impacted by a vehicle, it rotates around the edge of the cross-section 11 near the far end as the pressure center, and the movement direction of the limiting rod 31 is also arc-shaped. Therefore, the cross-sections of the first limiting groove 412 and the second limiting groove 413 are both arc-shaped. Specifically, the positional relationship between the first limiting groove 412 and the second limiting groove 413 is as follows: when the baffle 3 is horizontally set, the far end of the baffle 3 is taken as the front side, and the near end of the baffle 3 is taken as the rear side. The arc of the first limiting groove 412 and the arc of the second limiting groove 413 are arc-shaped. The arcs of both grooves bulge rearward, and the first limiting groove 412 is located in front of the second limiting groove 413. It can be understood that in order for the limiting rod 31 to function as a limiting rod, the bottom ends of the first limiting groove 412 and the second limiting groove 413 need to overlap (connect), allowing the limiting rod 31 to slide within the first and second limiting grooves 412 and 413. When the baffle 3 is horizontally positioned, the limiting rod 31 is located at the top of the first limiting groove 412. When the baffle 3 is raised, the limiting rod 31 is located at the bottom end of both the first and second limiting grooves 412 and 413. When the baffle 3 is impacted by a vehicle, the limiting rod 31 moves along the extension direction of the second limiting groove 413.

[0048] Existing technology can damage the barrier and scratch the vehicle chassis when a vehicle forcibly passes through it. To address this, the anti-collision smart lock provided in Embodiment 1 of this utility model uses a magnetic attraction method to fix the barrier 3 and the rotating shaft 1. When the barrier 3 is impacted by a vehicle, it can separate from the rotating shaft 1, preventing damage to the barrier 3 or the rotating shaft 1 due to rigid stress. Furthermore, when the barrier 3 and the rotating shaft 1 are separated, the barrier 3 cannot maintain its tilted, raised state, thus preventing continuous contact with the vehicle chassis and avoiding scratches to the chassis. By setting a limiting rod 31 on the barrier 3 and a first limiting groove 412 and a second limiting groove 413 on the limiting plate 41, the movement path of the barrier 3 can be limited, allowing the barrier 3 to return to the state of magnetic connection with the rotating shaft 1.

[0049] like Figure 2 As shown, the anti-collision smart lock provided in Embodiment 1 of this utility model preferably includes a spring 4131 in the second limiting groove 413 to prevent the limiting rod 31 from directly impacting the top of the second limiting groove 413 due to the large force exerted on the baffle 3, and to prevent the limiting rod 31 from being damaged due to rigid collision with the second limiting groove 413. The spring 4131 is bent along the extension direction of the second limiting groove 413, and one end of the spring 4131 is fixed to the top of the second limiting groove 413. This allows the spring 4131 to buffer the limiting rod 31 when it is squeezed by the limiting rod 31, and the baffle 3 can be quickly reset by the elastic potential energy accumulated after the spring 4131 is squeezed.

[0050] like Figure 3 As shown, the anti-collision smart lock provided in Embodiment 1 of this utility model preferably includes a limiting rod 31 that needs to collide with the inner wall of the first limiting groove 412 or the second limiting groove 413 when it moves within the first limiting groove 412 or the second limiting groove 413. To prevent the limiting rod 31 from being unable to move normally due to external force pressing against the inner wall of the first limiting groove 412 or the second limiting groove 413, the limiting rod 31 includes a limiting rod body 311 and a cylinder 312. The shape of the cylinder 312 will be described here. The cylinder 312 is vertically arranged and has an annular cross-section with a cylindrical internal space for placing the limiting rod body 311. The limiting rod body 311 is sleeved inside the cylinder 312, and the limiting rod body 311 and the cylinder 312 are rotatably fixed. Here, the limiting rod body 311 and the cylinder 312 are fixed by bearings. It should be noted that when the limiting rod 31 is located in the first limiting groove 412 or the second limiting groove 413, the side wall of the cylinder 312 is in close contact with the inner wall of the first limiting groove 412 or the inner wall of the second limiting groove 413.

[0051] like Figure 1 As shown in Embodiment 1 of this utility model, the anti-collision smart lock preferably has an elastic element 32 at the far end of the baffle 3. The elastic element 32 can replace the baffle 3 to make direct contact with the vehicle chassis. The elastic element 32 can be made of plastic or rubber and has elasticity, which further reduces the rigid collision between the baffle 3 and the vehicle chassis, thereby avoiding wear between the baffle 3 and the vehicle chassis, thus extending the service life of the baffle 3 and preventing scratches on the vehicle chassis.

[0052] like Figure 1As shown in Embodiment 1 of this utility model, the anti-collision smart lock is preferably designed to further protect the vehicle chassis and prevent the baffle 3 from scratching the vehicle chassis. The outer end of the elastic member 32 is rounded. The rounded elastic member 32 can increase the contact area with the vehicle chassis and reduce the pressure between the elastic member 32 and the vehicle chassis, thereby better protecting the vehicle chassis through the elastic member 32.

[0053] like Figure 4 As shown, the anti-impact smart lock provided in Embodiment 1 of this utility model preferably has a rounded corner at the intersection of the cross-sectional plane 11 and the outer side wall of the rotating shaft 1, so that when the baffle 3 is rotated under force, the rigid contact with the edge is reduced. The rounded corner design can increase the contact area with the surface of the baffle 3 and reduce the pressure generated on the surface of the baffle 3, thereby avoiding damage to the baffle 3. The rounded corner design can also be made of an elastic material.

[0054] In summary, the anti-collision smart ground lock provided by this utility model can solve the problem that the baffle will be damaged and the vehicle chassis will be scratched when a vehicle forcibly passes through it; thus extending the service life of the ground lock baffle and preventing scratches on the vehicle chassis.
