[0002] A parking ground lock is a mechanical device installed on the ground to prevent other vehicles from occupying the parking space. To park a vehicle in a parking space, the ground lock is opened and the barrier is lowered. To leave the space, the barrier is raised to prevent the space from being occupied by other vehicles.

[0003] Existing parking floor locks include manual and automatic lifts. Manual lifts, which require users to get in and out of the vehicle to lift the blocking member, have been gradually replaced by automatic lifts. Automatic lift parking floor locks typically include a drive mechanism, a transmission mechanism, and a blocking member. The drive mechanism drives the transmission mechanism, which in turn drives the blocking member to automatically rise and fall.

[0004] Currently, the blocking member adopts a single-plate lifting and lowering solution, which rotates around one side of the blocking plate to achieve the up and down function of the blocking plate. However, the single-plate lifting and lowering solution makes it easy for the car to escape from the sloped side. Summary of the Invention

[0005] The object of the present invention is to provide a blocking plate and a parking ground lock having the same, so as to overcome the problem of unilateral escape of the existing single-plate blocking plate.

[0033] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the embodiments and drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0035] like Figures 1 to 5 As shown, the present invention provides a parking ground lock 100, which mainly includes a base plate 10, a blocking plate 20 arranged on one side of the base plate 10, a driving mechanism 30 and a transmission mechanism 40, wherein the transmission mechanism 40 is respectively connected to the blocking plate 20 and the driving mechanism 30, wherein the driving mechanism 30 drives the transmission mechanism 40 to drive the blocking plate 20 to rise and fall relative to the base plate 10, thereby enabling vehicles to enter and exit the parking space and blocking other vehicles from entering the parking space.

[0036] It should be noted that when the parking ground lock 100 is fixed to the ground where the parking space is located, it is located in the middle area of ​​the parking space. When a vehicle is parked in the parking space, the parking ground lock 100 is located between the vehicle chassis and the ground. Due to the limited space between the vehicle chassis and the ground, the size of the parking ground lock 100 needs to be reduced. Under the premise of satisfying the parking ground lock's parking space occupation function, it is also necessary to ensure that the vehicle enters and exits the parking space without affecting the vehicle.

[0037] In this embodiment, there are two transmission mechanisms 40 , and the two transmission mechanisms 40 are disposed on two opposite sides of the blocking plate 20 .

[0038] The parking ground lock 100 further includes a housing 50 , which is assembled on one side of the base plate 10 . The driving mechanism 30 and the transmission mechanism 40 are respectively located in the space between the housing 50 and the base plate 10 .

[0039] The parking ground lock 100 provided by the present invention has the advantages of being compact, having a stable lifting and lowering motion of the blocking plate, having high blocking efficiency, and being able to avoid malicious collisions.

[0040] like Figure 5 、 Figures 8 to 11As shown, the transmission mechanism 40 connects the driving structure 30 and the blocking plate 20 . The driving force generated by the driving structure 30 is transmitted to the blocking plate 20 through the transmission mechanism 40 , thereby driving the blocking plate 20 to move up and down.

[0041] Specifically, the transmission mechanism 40 includes a rotating structure, which includes a first bracket 41, a first transmission gear 42, a screw rod 43 and a plurality of first balls 44. The first bracket 41 includes a first axial hole 411 and a first accommodating groove 412. The first axial hole 411 is located at the bottom 4121 of the first accommodating groove 412; the screw rod 42 is rotatably inserted into the first axial hole 411; the first transmission gear 42 is fixedly connected to the screw rod 43; a plurality of first balls 44 are arranged in the first accommodating groove 412, and the plurality of first balls 44 are clamped between the first transmission gear 42 and the first bracket 41.

[0042] In this embodiment, a plurality of first balls 44 are clamped between the first transmission gear 42 and the first bracket 41, reducing frictional resistance during the rotation of the screw 43. Compared to existing rotating structures that combine roller bearings with a rotating member, the rotating structure of the present invention utilizes a groove for accommodating the balls formed in the bracket, allowing the screw, serving as the rotating member, to directly contact the balls, thereby replacing the existing ball bearings and reducing frictional resistance during the screw's rotation. Since independent ball bearings are not required, the bracket is smaller, reducing its occupied space.

[0043] In addition, the production cost is reduced by replacing independent ball bearings with a plurality of balls.

[0044] In a preferred embodiment, the first transmission gear 42 and the screw rod 43 are fixedly connected in a manner including welding, integral molding, etc. Preferably, the first transmission gear 42 is located in the middle of the screw rod 43 .

[0045] Continue to refer to Figures 8 to 11 The first transmission gear 42 includes a first surface 421, on which a first annular protrusion 422 protrudes. The first annular protrusion 422 extends into the first accommodating groove 412, wherein a plurality of first balls 14 are confined in the space between the first annular protrusion 422 and the groove wall 4122 of the first accommodating groove 412, so that the plurality of first balls 44 will not fall off.

[0046] In a preferred embodiment, there is a gap between the top of the first annular protrusion 422 and the bottom 4121 of the first accommodating groove 412, that is, the top of the first annular protrusion 422 does not contact the bottom 4121, so that the screw rod 43 and the first transmission gear 42 can rotate smoothly.

[0047] In this embodiment, a plurality of first balls 44 are closely arranged around the outer surface of the screw rod 43 .

[0048] Furthermore, the rotating structure also includes a second bracket 45 and a plurality of second balls 46. The second bracket 45 includes a second axial hole 451 and a second accommodating groove 452. The second axial hole 451 is located at the bottom 4521 of the second accommodating groove 452. The screw rod 43 is rotatably inserted into the second axial hole 451, so that the first transmission gear 42 is clamped between the first bracket 41 and the second bracket 45. The plurality of second balls 46 are arranged in the second accommodating groove 452, and the plurality of second balls 46 are clamped between the first transmission gear 42 and the second bracket 46.

[0049] The first transmission gear 42 includes a second surface 423, which is opposite to the first surface 421. The second surface 423 is arranged on a second annular protrusion 424 opposite to the second accommodating groove 452. The second annular protrusion 424 extends into the second accommodating groove 452. A plurality of second balls 46 are confined in the space between the second annular protrusion 424 and the groove wall 4522 of the second accommodating groove 452, so that the plurality of second balls 46 will not fall off.

[0050] In a preferred embodiment, there is a gap between the top of the second annular protrusion 424 and the bottom 4521 of the second accommodating groove 452, that is, the top of the second annular protrusion 424 does not contact the bottom 4521 of the second accommodating groove 452, so that the screw rod 43 and the first transmission gear 42 can rotate smoothly.

[0051] In this embodiment, a plurality of second balls 46 are closely arranged around the outer surface of the screw rod 43 .

[0052] like Figures 8 to 10 As shown, the first bracket 41 and the second bracket 45 are respectively inverted L-shaped structures.

[0053] The top of the first bracket 41 of the inverted L-shaped structure includes a fixing seat 413, and the top of the second bracket 45 of the inverted L-shaped structure includes a fixing seat 453, wherein the fixing seats 413 and 453 are fixed to the housing 50 respectively. In addition, the screw rod 43 is provided in the first shaft hole 411 at the bottom of the first bracket 41 of the inverted L-shaped structure and the second shaft hole 451 at the bottom of the second bracket 45.

[0054] The first bracket 41 and the second bracket 45 are arranged opposite to each other, and the extension direction of the fixing seat 413 is opposite to the extension direction of the fixing seat 453. The rotating structure is arranged in the space between the bottom of the fixing seats 413 and 453 and the bottom plate 10, which can improve the space utilization of the first bracket 41 and the second bracket 45. At the same time, it also has the advantage of convenient installation and maintenance.

[0055] Continue to refer to Figures 8 to 11The rotating structure also includes a rotating shaft 61, a second transmission gear 62, a first bearing 63, a second bearing 64 and a bevel gear 65. The second transmission gear 62, the first bearing 63 and the second bearing 64 respectively fix the rotating shaft 61. The first bearing 63 is arranged in the bearing hole 414 of the first bracket 41, and the second bearing 64 is arranged in the bearing hole 454 of the second bracket 45. The second transmission gear 62 engages with the first transmission gear 42; the bevel gear 65 is fixedly connected to one end of the rotating shaft 61; wherein, the bevel gear 65 is located on the side of the first bracket 41 away from the second transmission gear 62.

[0056] In this embodiment, the outer rings of the first bearing 63 and the second bearing 64 are respectively fixed in the bearing hole 414 of the first bracket 41 and the bearing hole 454 of the second bracket 45; the inner rings of the first bearing 63 and the second bearing 64 are respectively fixedly connected to the rotating shaft 61.

[0057] Furthermore, the bearing hole 414 of the first bracket 41 and the bearing hole 454 of the second bracket 45 are respectively located obliquely above the first shaft hole 411 and the second shaft hole 451 .

[0058] Combine Figures 3 to 5 、 Figure 8 As shown, sliding nuts 70 are respectively provided at opposite ends of the screw rod 43, and the sliding nuts 70 are threadedly connected to the screw rod 43. The rotation of the screw rod 43 drives the sliding nuts 70 to slide back and forth along the screw rod 43.

[0059] In a preferred embodiment, the sliding nut 70 is fixedly connected to the blocking plate 20 , wherein the sliding nut 70 slides back and forth along the screw rod 43 to drive the blocking plate 20 to move up and down.

[0060] Reference Figures 1 to 7 As shown, the baffle 20 includes a plurality of first baffles 21, a plurality of second baffles 22, a central axis 23, a first cross bar 24 and a second cross bar 25. Each first baffle 21 and each second baffle 22 are rotatably connected to the central axis 23, and each first baffle 21 and each second baffle 22 are alternately arranged; the first cross bar 24 and the second cross bar 25 are relatively arranged, one end of each first baffle 21 is connected to the first cross bar 24, and one end of each second baffle 22 is connected to the second cross bar 25; the first cross bar 24 and the second cross bar 25 are respectively connected to the sliding nuts 70 at both ends of the screw rod 43; wherein, the sliding nut 70 slides to drive the first cross bar 24 and the second cross bar 25 to move, so that the plurality of first baffles 21 and the plurality of second baffles 22 rotate around the rotating shaft 23, thereby realizing the lifting and lowering of the plurality of first baffles 21 and the plurality of second baffles 22.

[0061] Specifically, when the sliding nut 70 slides outward along the screw rod 43, that is, slides in the direction away from the first bracket 41 and the second bracket 42, it pushes the first cross bar 24 and the second cross bar 25 to move outward, and the first baffles 21 and the second baffles 22 rotate and move downward around the center axis 23 respectively; when the sliding nut 70 slides inward along the screw rod 43, that is, slides in the direction close to the first bracket 41 and the second bracket 42, it pushes the first cross bar 24 and the second cross bar 25 to move inward, and the first baffles 21 and the second baffles 22 rotate and move upward around the center axis 23 respectively.

[0062] In this embodiment, a number of first baffles 21 and a number of second baffles 22 rotate and move downward around the central axis 23 to return to their initial positions, and the alternatingly arranged number of first baffles 21 and a number of second baffles 22 form a flat arc surface to facilitate the passage of vehicles; a number of first baffles 21 and a number of second baffles 22 rotate and move upward around the central axis 23 to enter the blocking position, and each alternating first baffle 21 and each second baffle 22 form an X-shaped cross blocking structure to prevent vehicles from entering and exiting the parking space and avoid the problem of vehicle escape.

[0063] That is, when the first cross bar 24 and the second cross bar 25 approach each other, the first baffles 21 and the second baffles 22 rotating around the central axis 23 rise upward and enter the blocking position; when the first cross bar 24 and the second cross bar 26 move away from each other, the first baffles 21 and the second baffles 22 rotating around the central axis 23 fall downward and return to the initial position.

[0064] It should be noted that in other embodiments of the present invention, when the first cross bar and the second cross bar approach each other, the several first baffles and the several second baffles rotating around the central axis drop downward and reset to the initial position; when the first cross bar and the second cross bar move away from each other, the several first baffles and the several second baffles rotating around the central axis rise upward and enter the blocking position.

[0065] In other words, the first crossbar and the second crossbar move away from or toward each other, driving the first baffles and the second baffles to rotate around the central axis, so that the first baffles and the second baffles switch between the initial position and the blocking position.

[0066] like Figures 1 to 7 As shown, the first baffle 21 and the second baffle 222 are arc-shaped baffles, and the central axis 23 is arranged in the middle of the arc-shaped baffles.

[0067] The first crossbar 24 is provided with a plurality of first limiting members 241 . The plurality of first limiting members 241 and the plurality of first baffles 21 are alternately arranged on the first crossbar 24 . The first limiting members 241 are used to limit the axial displacement of the plurality of first baffles 21 when rotating around the central axis 23 .

[0068] The first limiting member 241 is, for example, a hollow column or a C-shaped column sleeved on the first crossbar 24 .

[0069] The second crossbar 25 is provided with a plurality of second limiting members 251 . The plurality of second limiting members 251 and the plurality of second baffles 22 are alternately arranged on the second crossbar 25 . The second limiting members 251 are used to limit the axial displacement of the plurality of second baffles 22 when rotating around the central axis 23 .

[0070] The second limiting member 251 is, for example, a hollow column or a C-shaped column sleeved on the second crossbar 25 .

[0071] In addition, the opposite ends of the first cross bar 24 and the second cross bar 25 are respectively combined in the slide groove 51 of the outer shell 50. When the first cross bar 24 and the second cross bar 25 approach each other so that the first baffle 21 and the second baffle 22 are raised, when the first baffles 21 and the second baffles 22 are lifted to the highest position, the first cross bar 24 and the second cross bar 25 are respectively stopped by the side walls of the slide groove 51. Even if the screw rod 43 is continued to be driven to rotate, the first baffles 21 and the second baffles 22 will not continue to be lifted.

[0072] In addition, when the first cross bar 24 and the second cross bar 25 are respectively stopped by the side walls of the sliding groove 51 , the driving motor 31 can be controlled to stop working, thereby increasing the service life of the parking ground lock 100 .

[0073] In order to increase the rotational stability of the first baffle 21 and the second baffle 22 around the central axis 23, the end of the first baffle 21 away from the first cross bar 24 is connected to the third cross bar 26; the end of the second baffle 22 away from the second cross bar 25 is connected to the fourth cross bar 27; wherein, when the blocking plate 20 is in the initial position, the third cross bar 26 and the second cross bar 25 are adjacent; the first cross bar 24 and the fourth cross bar 27 are adjacent.

[0074] In this embodiment, the third cross bar 26 is located inside the second cross bar 25 , and the fourth cross bar 27 is located inside the first cross bar 27 .

[0075] Continue to refer to Figures 2 to 7The first baffle 21 is provided with a first recess 211 near the first cross bar 24; the second baffle 22 is provided with a second recess 221 near the second cross bar 25; wherein, the third cross bar 26 is provided with a plurality of first engaging members 261, and the plurality of first engaging members 261 and the first baffle 21 are arranged alternately; the fourth cross bar 27 is provided with a plurality of second engaging members 271, and the plurality of second engaging members 271 and the second baffle 22 are arranged alternately; wherein, when the blocking plate 20 is in the initial position, the first engaging member 261 is snapped into the second recess 221, and the second engaging member 271 is snapped into the first recess 211, so that the side surface of the blocking plate 20 away from the bottom plate 10 is a smooth arc surface, and the smooth arc surface makes it more convenient for the vehicle to enter and exit.

[0076] A plurality of first engaging members 261 and a plurality of second engaging members 271 can respectively limit the axial displacement of the first baffle 21 and the second baffle 22 rotating around the central axis 23; in addition, the first engaging member 261 and the second recess 221 of the second baffle 22 are engaged, and the second engaging member 271 and the first recess 211 of the first baffle 21 are engaged, so that the first baffle 21 and the second baffle 22 are restricted to each other, so that the baffle 20 in the initial position is more stable as a whole, and the problem of the first baffle 21 or the second baffle 22 being prone to warping occurs.

[0077] In this embodiment, the plurality of first engaging members 261 and the plurality of second recesses 221 are opposite to each other one by one, and the plurality of second engaging members 271 and the plurality of first recesses 211 are opposite to each other one by one.

[0078] In a preferred embodiment, the first engaging member 261 and the second engaging member 271 are respectively hollow columns or C-shaped columns.

[0079] In a preferred embodiment, the first recess 211 and the first baffle 21 are, for example, integrally formed. Similarly, the second recess 221 and the second baffle 22 are, for example, also integrally formed.

[0080] The first baffle 21 has first openings at opposite ends thereof, through which the first cross bar 24 and a plurality of first limiting members 241 as well as the third cross bar 26 and a plurality of first engaging members 261 are respectively passed; the second baffle 22 has second openings at opposite ends thereof, through which the second cross bar 25 and a plurality of second limiting members 251 as well as the fourth cross bar 27 and a plurality of second engaging members 271 are respectively disposed.

[0081] Combine Figures 1 to 11 , the lifting process of the blocking plate 20 is described in detail.

[0082] The driving mechanism 30 and the transmission mechanism 40 are respectively fixed on the surface of one side of the base plate 10. The driving mechanism 30 includes a driving motor 31, a driving shaft 32 and a driving bevel gear 33. The transmission mechanism 40 also includes a first transmission bevel gear 81, a transmission shaft 82, a second transmission bevel gear 83 and a third transmission bevel gear 84, wherein the driving bevel gear 33 engages with the transmission bevel gear 81; the first transmission bevel gear 81, the second transmission bevel gear 83 and the third transmission bevel gear 84 are respectively fixedly connected to the transmission shaft 82, wherein the first transmission bevel gear 81 and the third transmission bevel gear 84 are respectively arranged at opposite ends of the transmission shaft 82; the second transmission bevel gear 83 is close to the first transmission bevel gear 81 and engages with the bevel gear 65.

[0083] In this embodiment, an inverted L-shaped fixing bracket 85 is further included, and the second transmission bevel gear 83 and the first transmission bevel gear 81 are respectively located on both sides of the fixing bracket 85 .

[0084] In addition, the fixed bracket 85 includes a third bearing hole 851 and a third bearing. The third bearing is arranged in the third bearing hole 851, and the outer ring of the third bearing is fixedly connected to the fixed bracket 85; the inner ring of the third bearing is fixedly connected to the outer side of the transmission shaft 82 to reduce the rotational friction resistance of the transmission shaft 82.

[0085] In this embodiment, there are two rotating structures, for example, which are symmetrically arranged on opposite sides of the blocking plate 20 to improve the stability of the lifting and lowering of the blocking plate 20 .

[0086] The driving motor 31 drives the driving shaft 32 to rotate the driving bevel gear 33, the driving bevel gear 33 rotates and drives the first transmission bevel gear 81 to rotate, the first transmission bevel gear 81 drives the transmission shaft 82 to rotate, the transmission shaft 82 rotates and drives the second transmission bevel gear 83 and the third transmission bevel gear 84 to rotate, the second transmission bevel gear 83 and the third transmission bevel gear 84 rotate and respectively drive the bevel gear 65 to rotate, the bevel gear 65 rotates and drives the rotating shaft 61 to rotate, the rotating shaft 61 rotates and drives the second transmission gear 62 to rotate, the second transmission gear 62 rotates and drives the first transmission gear 42 to rotate, the first transmission gear 42 rotates and drives the screw rod 43 to rotate, the screw rod 43 rotates and drives the sliding nut 70 to slide along the screw rod 43, so that telescopic movement is formed between the screw rod 43 and the sliding nut 70.

[0087] Furthermore, the telescopic movement of the sliding nut 70 drives the first crossbar 24 and the second crossbar 25 to move closer to or away from each other, so that the first baffles 21 and the second baffles 22 can move up and down on the surface of one side of the bottom plate 10 .

[0088] Preferably, in order to ensure smooth lifting and lowering of the blocking plate 20 , the first crossbar 24 and the second crossbar 25 are suspended on the surface of one side of the bottom plate 10 , close to but not in contact with the surface of one side of the bottom plate 10 .

[0089] The present invention also provides a detection structure that can prevent the parking ground lock 100 from being damaged due to malicious collisions.

[0090] like Figures 1 to 4 、 Figure 12 and Figure 13 As shown, the detection structure includes a strain gauge 13, which is mounted on the base plate 10 and electrically connected to a drive motor 31 of a drive mechanism 30. When the strain gauge 13 senses deformation of the base plate 10, it outputs a signal to the drive motor 31, which activates the drive mechanism and drives the barrier plate 20 down to its initial position. In this initial position, the barrier plate 20 is at its lowest position, allowing vehicles to enter and exit the parking space freely.

[0091] By detecting the deformation of the bottom plate 10 through the strain gauge 13, the blocking plate 20 is automatically lowered, which facilitates the passage of vehicles and helps to overcome the problem of damage to the vehicle lock 100 caused by vehicle collision.

[0092] In a preferred embodiment, the base plate 10 includes a first side surface 11 and a second side surface 12 relative to each other, and a strain gauge 13 is provided on the first side surface 11; a gasket is provided on the second side surface 12; wherein, the strain gauge 13 is used to sense the deformation of the base plate 10; the gasket protrudes from the second side surface 12, so that there is a gap between the base plate 10 and the ground of the parking space, and the gap is used to provide deformation space for the base plate 10.

[0093] The strain gauge 13 is disposed on the first side surface 11 and faces the blocking plate 20 , so as to directly sense the deformation of the bottom plate 10 caused by the impact of the blocking plate 20 by an external force.

[0094] The number of the gaskets is, for example, four, and the four gaskets are disposed at the four corners of the second side surface of the bottom plate 10 .

[0095] In a preferred embodiment, the strain gauge 13 is made of an elastic material, preferably a strain gauge made of a low-carbon steel material, that is, a low-carbon steel strain gauge, the stiffness of which should not be too large to ensure sufficient elasticity standards.

[0096] In a preferred embodiment, a groove 15 is provided on the first side surface 11 of the bottom plate 10, and the strain gauge 13 is embedded in the groove 15. The groove 15 reduces the thickness of the bottom plate 10, thereby making it easier to sense the deformation of the bottom plate 10 caused by external force.

[0097] In a preferred embodiment, there may be a plurality of strain gauges 13 , and the plurality of strain gauges 13 are, for example, disposed at corners and / or a central area of ​​the first side surface 11 of the base plate 10 .

[0098] In a preferred embodiment, the strain gauge 13 is electrically connected to the driving mechanism 30 . For example, the strain gauge 13 is electrically connected to the driving motor 31 via a wire.

[0099] In this embodiment, when the strain gauge 13 senses the deformation of the bottom plate 10, it is determined that the parking ground lock 100 is impacted by an external force. According to the deformation, the drive motor 31 in the drive mechanism 30 is controlled to start, so that the blocking plate 20 moves downward and returns to the initial position.

[0100] The deformation of the bottom plate 10 is detected by the strain gauge 13 , and the blocking plate 20 of the parking ground lock 100 is driven to descend and reset, thereby increasing the safety of the vehicle passing through.

[0101] In addition, when the strain gauge 10 detects that the base plate 10 has multiple deformations within a preset time, or the strain detected by the strain gauge 10 exceeds the preset pressure threshold, an alarm is output to indicate the presence of a malicious collision, and intervention is made in the formation of a malicious collision, which can significantly improve the service life of the vehicle lock.

[0102] In summary, the present invention provides a baffle and a parking ground lock having the same, wherein the first cross bar and the second cross bar are aligned with or separated from each other, so that the alternatingly arranged first baffles and the second baffles are rotated and raised or lowered around the central axis respectively. After the first baffles and the second baffles are lowered, a flat arc-shaped surface is formed to facilitate the passage of vehicles; after the first baffles and the second baffles are raised, a cross-blocking structure is formed to improve the blocking effectiveness and avoid the problem of vehicle escape.
