Description

Technical Field

[0001] This invention relates to the field of parking lock technology, and in particular to a parking space lock. Background Technology

[0002] A parking lock is a mechanical device installed on the ground that can be used to prevent others from occupying a parking space or to restrict a vehicle from leaving the parking space.

[0003] A parking space lock typically includes a stop, a detection probe, and a drive assembly. The drive assembly is connected to the stop, and the detection probe is used to detect whether a vehicle is in the parking space. When the detection probe detects a vehicle entering the parking space, the drive assembly causes the stop to rise, preventing the vehicle from leaving the space. Before this, the detection probe needs to send out detection signals in real time to detect whether a vehicle has entered. Therefore, even when the parking space lock is in standby mode, the detection probe still consumes a significant amount of power to send out detection signals. Summary of the Invention

[0004] The present invention aims to provide a parking lock to solve the technical problem that parking locks consume a lot of energy in standby mode in the prior art.

[0005] This invention provides a parking space lock, which includes:

[0006] Mounting base;

[0007] A stop is connected to the mounting base, and the lower part of the stop has an adjustable gap that allows the stop to shift downward.

[0008] An elastic element that provides the stop with an upward resetting force within the movement gap; the elastic element elastically connects the mounting base and the stop.

[0009] A position switch capable of detecting downward displacement of a stop, the position switch being mounted on a mounting base or the stop, the position switch including a trigger end, the trigger end being triggered when the stop is displaced downward within the movement gap;

[0010] A drive assembly capable of raising or lowering the stop relative to the mounting base; the drive assembly is connected to the stop.

[0011] Optionally, the stop is rotatably connected to the mounting base, and the drive assembly can drive the stop to rotate relative to the mounting base to a raised or lowered state.

[0012] Optionally, the mounting base is provided with a connection hole, and the stop includes a rotating shaft and a baffle. The rotating shaft is rotatably connected to the connection hole, and the drive assembly is connected to the rotating shaft.

[0013] The movement clearances include a first clearance that allows the baffle to deflect downward when it is in the lowered state, and a second clearance that allows the shaft to deflect downward when it is in the lowered state. The first clearance is located below the baffle when it is in the lowered state, and the second clearance is located below the shaft when it is in the lowered state. The elastic element provides an upward reset force for the shaft and the baffle.

[0014] Optionally, the connection hole includes a first connection hole and a second connection hole;

[0015] The rotating shaft has a first end and a second end, which are located on the two sides of the baffle, respectively. The first end is rotatably connected to the first connecting hole, and a second gap is provided in the first connecting hole. The second gap is located below the first end when it is in the lowered state. The second end is rotatably connected to the second connecting hole, and the outer diameter of the second end is adapted to the inner diameter of the second connecting hole.

[0016] Optionally, the end of the second end extends out of the second connection hole in a direction away from the first end, and the drive assembly is connected to the end of the first end.

[0017] Optionally, the second end is rotated to limit the drive assembly to prevent the baffle from rotating downwards around the axis of the shaft under its own weight.

[0018] Optionally, the position switch is mounted on the mounting base, with the position switch located below the first end and the trigger end opposite to the first end; or,

[0019] The position switch is installed at the first end, with the trigger end facing downwards and opposite the mounting base; or...

[0020] The position switch is mounted on a baffle; when the baffle is in the lowered state, the trigger terminal faces downwards and is opposite to the mounting base; or...

[0021] The position switch is mounted on the mounting base. The position switch is located below the baffle when the baffle is in the lowered state, with the trigger end facing upward and opposite to the baffle.

[0022] Optionally, the position switch is a micro switch or a proximity switch.

[0023] Optionally, the parking lock also includes a gyroscope capable of sensing the movement of the stop, and the gyroscope is connected to the stop.

[0024] Optionally, the parking lock also includes a detection module capable of detecting whether there is a vehicle in the parking space, as well as an electronic control system and a battery. The detection module is mounted on a mounting base or stop, the electronic control system is electrically connected to the position switch, drive assembly, gyroscope and detection module, and the battery is electrically connected to the position switch, drive assembly, gyroscope, detection module and electronic control system.

[0025] Compared with the prior art, in this embodiment of the invention, by providing an movable gap below the stop for downward offset, when a vehicle enters the parking space and its wheels press against the stop, the wheels can force the stop to offset downward within the movable gap, thereby triggering the trigger end of the position switch. This causes the drive assembly to lift the stop relative to the mounting base, thus restricting the vehicle from leaving the parking space. This parking lock in this embodiment of the invention transforms the mechanical action of the stop offsetting downward into a triggering action on the trigger end. When the stop is mechanically moved by the external force of the wheel, the trigger end is triggered, thereby enabling the parking lock to detect when a vehicle enters the parking space. Furthermore, during use, the position switch does not need to send detection signals outward in real time, resulting in low power consumption and energy saving when the parking lock is in standby mode. Moreover, by incorporating an elastic element, after the vehicle's wheels remove their pressure on the stop, the elastic element allows the stop to offset upward within the movable gap for reset, thus preparing for the next detection when a vehicle enters the parking space.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0039] Please see Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of a parking lock 1000 according to one embodiment of the present invention. Figure 2 yes Figure 1 The diagram shows another state of the parking lock 1000. The parking lock 1000 is installed on the ground where the parking space is located and can be used to restrict vehicles from leaving or entering the parking space.

[0040] Please refer to the following: Figure 3 and Figure 4 , Figure 3 yes Figure 1 The image shown is a partial enlarged view of part A of the parking lock 1000. Figure 4 yes Figure 1The diagram shows a cross-sectional view of the parking lock 1000 along the BB direction. The parking lock 1000 includes a mounting base 10, a stop 20, an elastic element 30, a position switch 40, and a drive assembly. The stop 20 is connected to the mounting base 10. A movable gap 101 is provided below the stop 20 to allow the stop 20 to shift downward. The elastic element 30 elastically connects the mounting base 10 and the stop 20. The elastic element 30 can provide the stop 20 with a spring force to reset upward within the movable gap 101. The position switch 40 is mounted on the mounting base 10 or the stop 20. The position switch 40 can detect the downward shift of the stop. The position switch 40 includes a trigger end 41. When the stop 20 shifts downward within the movable gap 101, the trigger end 41 can be triggered. The drive assembly is connected to the stop 20. The drive assembly can drive the stop 20 to rise or fall relative to the mounting base 10.

[0041] In this embodiment of the invention, by providing an movable gap 101 below the stop 20 for downward offset, when a vehicle enters the parking space and its wheels press against the stop 20, the wheels can force the stop 20 to offset downward within the movable gap 101, thereby triggering the trigger end 41 of the position switch 40. This causes the drive assembly to drive the stop 20 to rise relative to the mounting base 10, thus restricting the vehicle from leaving the parking space. The parking lock 1000 of this embodiment transforms the downward offset mechanical action of the stop 20 into a triggering action of the trigger end 41. When the stop 20 undergoes mechanical movement under the external force of the wheels, the trigger end 41 is triggered, thereby enabling the parking lock 1000 to sense when a vehicle enters the parking space. During use, the position switch 40 does not need to send detection signals in real time, resulting in low power consumption and energy saving when the parking lock 1000 is in standby mode.

[0042] Furthermore, by providing the elastic element 30, after the vehicle's wheels remove their pressure on the stop 20, the elastic element 30 can cause the stop 20 to shift upward within the movement gap 101 and reset, thereby preparing for the detection when the vehicle enters the parking space next time.

[0043] In practical use, the stop 20 has three states: a lowered state, a pressed-down state, and a raised state, such as... Figure 1 and Figure 4 As shown, the descending state is the position of the stop 20 after it has descended relative to the mounting base 10 and is located above the movable gap 101; the descending state is the initial state of the stop 20. The pressing state is the position of the stop 20 after it has shifted downwards in the descending state and compressed the space of the movable gap 101. Figure 2As shown, the raised state is the position of the stop 20 after it has been raised relative to the mounting base 10. By driving the stop 20 through the drive assembly, the stop 20 can be switched between the lowered state and the raised state. By the wheels driving onto and off the stop 20, the stop 20 can be switched between the pressed-down state and the lowered state. The aforementioned movement clearance 101 refers to the range of movement of the stop 20 as it shifts downward from the lowered state to the pressed-down state.

[0044] When the wheel drives onto the upper surface of the stop 20, the pressure exerted by the wheel on the stop 20 is downward. Under this pressure, the stop 20 shifts downward from a descending state to a pressed state. At the same time, the downward shift of the stop 20 also forces the elastic element 30 connected to it to undergo elastic deformation, causing the elastic element 30 to accumulate a certain potential energy. When the wheel leaves the upper surface of the stop 20, the elastic element 30 releases the potential energy and restores its elastic deformation, providing the stop 20 with an upward reset force. Under the action of the elastic force, the stop 20 shifts upward from a pressed state to a descending state and resets.

[0045] The downward offset of the stop 20 can be either the entire stop 20 offsetting downward to compress the space of the movable gap 101, or the stop 20 rotating downward around a certain support point or support surface to compress the space of the movable gap 101. As long as the stop 20 can produce a certain position change under the pressure of the wheel, it can trigger the trigger end 41 of the position switch 40 connected to the stop 20.

[0046] In practical use, the position switch 40 is used to detect whether the stop 20, when in the lowered state, makes a downward offset movement within the movement gap, thereby sensing whether a wheel has driven onto the stop 20. The position switch 40 can be a contact switch or a non-contact switch, as long as the mechanical movement of the stop 20 offsetting downward can trigger the trigger terminal 41 of the position switch 40. The contact switch can be a micro switch, and the non-contact switch can be a proximity switch.

[0047] In some embodiments, the stop 20 is rotatably connected to the mounting base 10, and the drive assembly can drive the stop 20 to rotate relative to the mounting base 10 to a raised or lowered state, allowing the stop 20 to switch between the raised and lowered states. With this configuration, the stop 20 can be raised to stand upright or lowered to lie flat by changing the rotation angle. The stop 20 does not need to be raised or lowered vertically in a direction perpendicular to the ground, avoiding the need to dig deep trenches in the ground to provide lowering space for the stop 20 when the parking lock 1000 is installed on the ground.

[0048] Specifically, such as Figure 2As shown, after the drive assembly drive stop 20 rotates and lifts relative to the mounting base 10 in the first direction F1, it is in a raised state. At this time, the stop 20 is upright relative to the ground, and the parking lock 1000 restricts the vehicle from driving out of or into the parking space. Figure 1 As shown, after the drive assembly drives the stop 20 to rotate and descend relative to the mounting base 10 in the second direction F2, it is in a lowered state. At this time, the stop 20 is flat relative to the ground, and the vehicle can drive out of or into the parking space. The first direction F1 and the second direction F2 are opposite.

[0049] In some other embodiments, the stop 20 is non-rotatably connected to the mounting base 10, and the stop 20 is slidably connected to the mounting base 10. The drive assembly can drive the stop 20 to slide upward relative to the mounting base 10 to be in a raised state, or slide downward relative to the mounting base 10 to be in a lowered state.

[0050] In some embodiments, the mounting base 10 is provided with a connection hole, and the stop 20 includes a rotating shaft 21 and a baffle 22. The rotating shaft 21 is rotatably connected to the connection hole, and a drive assembly is connected to the rotating shaft 21. The drive assembly can drive the rotating shaft 21 to rotate the baffle 22 relative to the mounting base 10 to a raised state or a lowered state. The movable gap 101 includes a first gap 1011 that allows the baffle 22 to deflect downward when it is in the lowered state, and a second gap 1012 that allows the rotating shaft 21 to deflect downward when it is in the lowered state. The first gap 1011 is located below the baffle 22 when it is in the lowered state, and the second gap 1012 is located below the rotating shaft 21 when it is in the lowered state. The elastic member 30 provides an upward reset force for the rotating shaft 21 and the baffle 22. Thus, when the wheel drives onto the baffle 22 and forces the baffle 22 to shift downward, the baffle 22 shifts downward within the first gap 1011, compressing the space of the first gap 1011. At the same time, the baffle 22 can drive the rotating shaft 21 to shift downward within the second gap 1012, so that both the rotating shaft 21 and the baffle 22 can shift downward and produce a large position change. The position changes produced by both the rotating shaft 21 and the baffle 22 can effectively trigger the trigger end 41 of the position switch 40, allowing the position switch 40 to be triggered by either the rotating shaft 21 or the baffle 22. In specific designs, the position switch 40 can be correspondingly set with the rotating shaft 21 or the baffle 22 as needed, providing different choices for the installation position of the position switch 40.

[0051] like Figure 4As shown, in some embodiments, the connecting hole includes a first connecting hole 111 and a second connecting hole 121. The rotating shaft 21 has a first end 211 and a second end 212, which are respectively located on the two sides of the baffle 22. The first end 211 is rotatably connected to the first connecting hole 111. A second gap 1012 is located in the first connecting hole 111. The second gap 1012 is located below the first end 211 when it is in a lowered state. The second end 212 is rotatably connected to the second connecting hole 121, and the outer diameter of the second end 212 is adapted to the inner diameter of the second connecting hole 121. With the above settings, after the second segment 212 is installed in the second connecting hole 121, the inner wall of the second connecting hole 121 can radially limit the second end 212, preventing the second end 212 from radially moving relative to the inner wall of the second connecting hole 121. The second end 212 can only rotate around its own axis within the second connecting hole 121, and the inner wall of the second connecting hole 121 provides support for the second end 212. When the wheel drives onto the baffle 22 and forces the baffle 22 to shift downward, the baffle 22 applies a downward torque to the rotating shaft 21 between the first end 211 and the second end 212, causing the rotating shaft 21 to... The shaft 21 bends downwards with the second connecting hole 121 as the support center, causing the first end 211 of the shaft 21 to shift downwards within the second gap 1012. Thus, both the shaft 21 and the baffle 22 can shift downwards and produce a large positional change. The positional changes produced by the shaft 21 and the baffle 22 can effectively trigger the trigger end 41 of the position switch 40. After the first end 211 shifts downwards by the size of the second gap 1012, the inner wall of the first connecting hole 111 can still support and limit the first end 211, preventing the first end 211 from shifting downwards excessively.

[0052] When the stop 20 is in the lowered state, the first end 211 and the second end 212 are collinear; when the stop 20 is in the pressed-down state, the first end 211 is biased downward relative to the second end 212. It can be understood that the shaft 21 is a rigid shaft, but under the action of the external force of the wheel, it can still undergo slight elastic deformation, allowing the shaft 21 to bend slightly downward about the second connecting hole 121 as the support center, so that the axis of the first end 211 is biased downward relative to the axis of the second end 212; after the external force of the wheel is removed, the elastic member 30 provides an upward elastic force to the stop 20 to assist the shaft 21 in bending upward about the second connecting hole 121 and returning to its original position, so that the first end 211 and the second end 212 are collinear again.

[0053] In some embodiments, the height direction of the first connecting hole 111 is the direction in which the first end 211 shifts vertically within the hole, and the height of the first connecting hole 111 is greater than the outer diameter of the first end 211, so as to allow the first connecting hole 111 to have a second gap 1012 for the first end 211 to shift vertically; the width of the first connecting hole 111 is equal to or greater than the outer diameter of the rotating shaft 21.

[0054] The first connecting hole 111 can be a slotted hole.

[0055] In some other embodiments, the first connecting hole 111 may also be other hole shapes, such as rectangular holes, elliptical holes, etc.

[0056] In some embodiments, the end of the second end 212 extends out of the second connecting hole 121 in a direction away from the first end 211, and the drive assembly is connected to the end of the first end 211. Thus, since the inner wall of the second connecting hole 121 has a radial limiting effect on the second end 212, during the downward elastic bending of the shaft 21 with the second connecting hole 121 as the support center, the height position of the end of the second end 212 remains unchanged, thereby preventing the downward elastic bending of the shaft 21 from affecting its fit with the drive assembly and ensuring a stable fit between the shaft 21 and the drive assembly.

[0057] In some other embodiments, a third gap is provided within the second connecting hole 121. The third gap is located below the second end 212 when it is in the lowered state, and the size of the third gap is the same as the size of the second gap. When the wheel drives onto the baffle 22 and forces the baffle 22 to drive the shaft 21 to shift downward, the first end 211 shifts downward in the first connecting hole 111 by the size of the second gap 1012, and the second end 212 shifts downward in the second connecting hole 121 by the size of the third gap.

[0058] It is understandable that the fit between the second end 212 and the drive assembly changes when the second end 212 shifts up and down. Therefore, it is necessary to ensure that the drive assembly does not interfere with the downward shift of the second end 212. After the second end 212 returns to its upward position, the drive assembly can still cooperate normally with the second end 212 to drive the second end 212 to raise or lower the stop 20 relative to the mounting base 10. For ease of understanding, let's take the motion transmission of the drive assembly through a worm gear and worm as an example. The worm gear is sleeved on the circumferential outer side of the second end 212 and fixed to the second end 212. The worm gear meshes with the worm, and the worm is located above the worm gear. When the second end 212 drives the worm gear to shift downward, the worm gear moves away from the worm. When the second end 212 drives the worm gear to return to its upward position, the worm gear and worm return to their normal fit, thereby ensuring the normal drive of the second end 212 by the drive assembly. Among them, a worm gear and worm with larger teeth can be selected so that the worm gear can still maintain its engagement with the worm as it moves away from the worm, thus preventing the worm gear from losing its rotation limit after disengaging from the worm and rotating around the axis of the rotating shaft 21.

[0059] In some other embodiments, the second gap 1012 is omitted, and the two ends of the rotating shaft 21 are radially limited to the first connecting hole 111 and the second connecting hole 121, respectively. The rotating shaft 21 can only rotate around its own axis within the connecting hole. One side of the baffle 22 is connected to the rotating shaft 21, and the elastic element 30 is connected to the rotating shaft 21 or the baffle 22 to keep the baffle 22 in a lowered state, that is, to keep the baffle 22 above the first gap 1011, so that after the wheel drives onto the baffle 22, the baffle 22 can be forced to rotate downward around the rotating shaft 21 to compress the first gap 1011.

[0060] Specifically, the elastic element 30 is a compression spring or a leaf spring, which is located below the baffle 22 when it is in the lowered state. The compression spring or leaf spring can provide an upward elastic force to the baffle 22 so that the baffle 22 remains in the lowered state. Alternatively, the elastic element 30 is a torsion spring, which is sleeved on the circumferential outer side of the rotating shaft 21. One torsion arm of the torsion spring is connected to the baffle 22, and the other torsion arm of the torsion spring is connected to the mounting base 10. The torsion spring can provide an upward elastic force to the baffle 22 so that the baffle 22 remains in the lowered state.

[0061] In some embodiments, the second end 212 is rotatably limited with the drive assembly to prevent the baffle 22 from rotating downwards around the axis of the shaft 21 under its own weight. By rotatably limiting the second end 212 of the shaft 21, the baffle 22 is allowed to remain in the lowered state, that is, above the second gap 1012, preventing the other end of the baffle 22 away from the shaft 21 from falling into contact with other components under its own weight. There is no need to provide a structure below the baffle 22 to support the baffle 22 and keep it above the second gap 1012, allowing the baffle 22 as a whole to move downwards together with the shaft 21 and produce a large positional change.

[0062] In some embodiments, the drive assembly includes a drive motor, a worm gear, and a worm wheel. The output end of the drive motor is connected to the worm gear. The worm wheel is sleeved on the circumferential outer side of the second end 212 and fixed to the second end 212. The worm wheel meshes with the worm gear, and the worm gear and worm wheel play a motion transmission role between the drive motor and the second end 212. When the drive motor is started, the output end of the drive motor drives the second end 212 to rotate sequentially through the worm gear and worm wheel. The second end 212 drives the baffle 22 to rotate together, thereby realizing the rotational lifting or lowering of the drive stop 20. The worm wheel and worm gear have good self-locking properties. The rotational limit between the second end 212 and the drive assembly can be achieved through the meshing between the worm wheel and worm gear. When the stop 20 is in the lowering state or during the downward offset of the stop 20, it can prevent the baffle 22 from rotating downward around the axis of the rotating shaft 21.

[0063] In other embodiments, motion transmission between the drive motor and the second end 212 can also be achieved through other drive components. For example, a first gear is sleeved on the circumferential outer side of the second end 212, and the first gear is fixed to the second end. The output end of the drive component is connected to a second gear, and the first and second gears mesh. The output end of the drive motor drives the second end 212 to rotate sequentially through the second gear and the first gear. The second end 212 drives the baffle 22 to rotate together, thereby realizing the rotational lifting or lowering of the drive stop 20. The drive motor can be a servo motor, which has good self-locking properties, so that the meshing between the second gear and the first gear connected to it can realize the rotational limit between the second end and the drive component. When the stop 20 is in the lowering state or during the downward offset of the stop 20, it can prevent the baffle 22 from rotating downward around the axis of the rotating shaft 21.

[0064] Multiple reduction gears can be installed between the first and second gears, meshing sequentially. One of the first reduction gears meshes with the first gear, and the last one meshes with the second gear. In practice, each reduction gear needs to be limited to rotate only around its own axis.

[0065] During use, because the baffle 22 needs to be raised to restrict vehicles from entering or leaving parking spaces, other components below the baffle 22 are exposed on the ground. This makes it easy for sand and other debris to accumulate on these components. When a wheel drives onto the baffle 22 and forces it to shift downwards, the bottom surface of the baffle 22 will come into contact with the other components below it, causing sand and other debris to scrape and damage the bottom surface of the baffle 22. Therefore, in some embodiments, the first gap 1011 is greater than or equal to the second gap 1012. As the wheel drives onto the stop 20 and forces it to deflect downwards, the center of the downward deflection of the stop 20 is located around the second connecting hole 121. Therefore, along the axial direction of the shaft 21, the further away from the second end 212 the stop 20 deflects downwards, the greater the distance. Since the first end 211 is located on the side of the baffle 22 away from the second connecting hole 121, the size of the second gap 1012 that the first end 211 deflects downwards within the first connecting hole 111 is the maximum distance that the stop 20 deflects downwards. The baffle 22 is closer to the second connecting hole 121 than the first end 211, so the distance that the baffle 22 deflects downwards is less than the size of the second gap 1012. Since the first gap 1011 is greater than or equal to the second gap 1012, a certain gap is still left below the baffle 22 after it deflects downwards. That is, the bottom surface of the baffle 22 always maintains a certain gap with other components, thereby preventing the baffle 22 from being scratched or damaged by sand, gravel, or other debris below it when it deflects downwards.

[0066] The size of the first gap 1011 can be set according to the actual situation. It is sufficient that the gap left below the baffle 22 after it is offset downwards can allow the baffle 22 to avoid small sand and gravel.

[0067] In some embodiments, the second gap 1012 is larger than the first gap 1011.

[0068] In some embodiments, the size of the second gap 1012 is 1 to 4 millimeters, that is, the first connecting hole 111 allows the first end 211 to be offset downward by 1 to 4 millimeters within the first connecting hole 111 and then abut against the lower wall of the first connecting hole 111. In this way, the elastic bending deformation of the shaft 21 can be limited, preventing the shaft 21 from being excessively bent and damaging the structure.

[0069] In some embodiments, the elastic member 30 elastically connects the mounting base 10 and the first end 211, and the elastic member 30 provides the first end 211 with an upward restoring force within the second gap 1012. When the stop member 20 is in the descending state, the stop member 20 as a whole is supported by the first end 211 and the second end 212 from the lower wall of the elastic member 30 and the second connecting hole 121, respectively. When the stop member 20 is in the pressed-down state, the stop member 20 as a whole is supported by the first end 211 and the second end 212 from the lower wall of the first connecting hole 111 and the lower wall of the second connecting hole 121, respectively. Since the center of the downward deflection of the stop 20 is located around the second connecting hole 121, and the first end 211 is located on the side of the baffle 22 away from the second connecting hole 121, the distance from the first end 211 to the second connecting hole 121 on the rotating shaft 21 is relatively long. Therefore, by setting the elastic element 30 at the position corresponding to the first end 211, the elastic force of the elastic element 30 acting on the stop 20 has a large lever arm, thereby enabling the elastic element 30 to generate a large torque on the stop 20, which is more conducive to the elastic element 30 supporting the stop 20 and resetting the stop 20.

[0070] In some embodiments, the mounting base 10 includes a first connecting base 11, a first connecting hole 111 is provided in the first connecting base 11, and the first connecting base 11 also has a receiving hole 112, which communicates with the first connecting hole 111. An elastic member 30 is received within the receiving hole 112, and both ends of the elastic member 30 are elastically connected to the lower wall of the receiving hole 112 and the first end 211, respectively. By providing the receiving hole 112 on the first connecting base 11 to house the elastic member 30, the space occupied by the first connecting base 11 itself is utilized, making the structure of the parking lock 1000 more compact and avoiding the need for additional space due to the elastic member 30. Furthermore, the receiving hole 112 can limit the elastic member 30, preventing it from deviating from its installation position during use, thus ensuring a stable elastic connection between the elastic member 30 and the rotating shaft 21.

[0071] In some embodiments, the mounting base 10 further includes a second connecting base 12, a second connecting hole 121 is disposed on the second connecting base 12, the first connecting base 11 and the second connecting base 12 are spaced apart, and the lowest point of the lower wall of the first connecting hole 111 is lower than the lowest point of the lower wall of the second connecting hole 121.

[0072] In some embodiments, both the first connector 11 and the second connector 12 are convex in shape.

[0073] In some other embodiments, the first connecting seat 11 and the second connecting seat 12 may be in other shapes, such as rectangular.

[0074] In some other embodiments, the first connecting seat 11 is a bushing, with a first connecting hole 111 located inside the bushing. The outer diameter of the first end 211 is adapted to the inner diameter of the first connecting hole 111, thereby allowing the inner wall of the first connecting hole 111 to radially limit the first end 211. The first end 211 can only rotate around its own axis within the first connecting hole 111. The bushing and the mounting seat 10 are slidably connected vertically, and a second gap 1012 is located below the bushing when it is in the lowered state.

[0075] The elastic element 30 can be disposed within the second gap 1012, and the elastic element 30 supports the bushing and can provide the bushing with an upward restoring force.

[0076] The bushing can be slidably connected to the mounting base 10 via bolts. Specifically, the bolt includes a stud and a nut. The nut is fixed to the end of the stud, and the end of the stud away from the nut has threads that are screwed into the mounting base 10. The other end of the stud near the nut is smooth and cylindrical. A limiting hole is provided on the side of the bushing, fitted outside the other end of the stud. The diameter of the limiting hole is larger than the outer diameter of the stud, allowing the bushing to offset relative to the stud when the shaft 21 shifts downwards with the second connecting hole 121 as the support center, thus avoiding interference with the shaft 21's offset. The nut is located above the limiting hole, and its diameter is larger than the limiting hole's diameter, preventing the bushing from detaching from the bolt from bottom to top.

[0077] Please see Figure 5 , Figure 5 yes Figure 1 The schematic diagram of the parking lock 1000 shown in cross-section along the CC direction illustrates that, in some embodiments, the parking lock 1000 further includes a pad 50, which includes an arc-shaped washer 51. The arc-shaped washer 51 is disposed in the first connecting hole 111 and located below the first end 211. The receiving hole 112 is located below the arc-shaped washer 51, and the first end 211 abuts against the inner peripheral sidewall 511 of the arc-shaped washer 51. The elastic element 30 is a compression spring. One end of the compression spring elastically abuts against the outer peripheral sidewall 512 of the arc-shaped washer 51, and the other end of the compression spring elastically abuts against the lower wall of the receiving hole 112. The compression spring provides an upward restoring force to the first end 211 through the arc-shaped washer 51. Under the action of the spring force, the arc-shaped washer 51 always remains tightly attached to the first end 211, and the arc-shaped washer 51 can shift up and down with the first end 211. By setting an arc-shaped washer 51 between the first end 211 and the compression spring, the elastic force transmitted by the compression spring to the first end 211 can be distributed more evenly, ensuring the elastic force of the compression spring on the first end 211 and providing a stable elastic force for the rotating shaft 21.

[0078] Optionally, the inner peripheral sidewall 511 of the arc-shaped gasket 51 is adapted to the outer peripheral sidewall of the first end 211, and the outer peripheral sidewall 512 of the arc-shaped gasket 51 is adapted to the lower wall of the first connecting hole 111.

[0079] To prevent the arc-shaped gasket 51 from detaching from the first connecting hole 111 when it shifts up and down with the first end 211, in some embodiments, the gasket 50 further includes a limiting post 52. The limiting post 52 is connected to the outer peripheral sidewall 512 of the arc-shaped gasket 51 and extends into the receiving hole 112. A compression spring is sleeved on the outside of the limiting post 52. The receiving hole 112 can limit the movement of the limiting post 52. When the limiting post 52 shifts up and down with the arc-shaped gasket 51, the limiting post 52 is always located inside the receiving hole 112. The receiving hole 112 guides the movement of the limiting post 52, so that the limiting post 52 moves along an axis parallel to or approximately parallel to the axis of the receiving hole 112, thereby limiting the arc-shaped gasket 51 and preventing the arc-shaped gasket 51 from detaching from the first connecting hole 111.

[0080] Of course, in some other embodiments, the limiting post 52 can be omitted, and the outer peripheral sidewall 512 of the arc-shaped gasket 51 is welded to the upper end of the compression spring so that the arc-shaped gasket 51 and the compression spring are fixed to each other, and the compression spring can limit the arc-shaped gasket 51 in the receiving hole 112.

[0081] In some other embodiments, the elastic element 30 is a tension spring, the receiving hole 112 is located above the first end 211, one end of the tension spring is fixed to the upper wall of the receiving hole 112, and the other end of the tension spring is fixed to the first end 211.

[0082] Please see Figure 6 and Figure 7 , Figure 6 This is a three-dimensional structural view of a parking lock 1000 provided in another embodiment of the present invention. Figure 7 for Figure 6 The enlarged view of part D of the parking lock 1000 shown shows that in some embodiments, the elastic element 30 includes a spiral body 31, a first torsion arm 32 and a second torsion arm 33. The first torsion arm 32 and the second torsion arm 33 are respectively connected to the two ends of the spiral body 31. The spiral body 31 is sleeved on the circumferential outer side of the first end 211. The first torsion arm 32 is fixed to the rotating shaft 21, and the second torsion arm 33 abuts against the mounting base 10. The elastic element 30 provides the first end 211 with an upward reset force within the second gap 1012, so that the stop 20 can be reset upward after the wheel leaves.

[0083] When the stop 20 is in the lowered state, the second torsion arm 33 elastically abuts against the mounting base 10 to prevent the stop 20 from shifting downward and compressing the movable gap 101. When the wheel drives onto the baffle 22 and forces the first end 211 and the baffle 22 to shift downward, the first end 211 forces the second torsion arm 33 to undergo elastic deformation, causing the second torsion arm 33 to accumulate a certain potential energy. When the wheel leaves the baffle 22, the second torsion arm 33 releases the potential energy and restores its elastic deformation, providing the first end 211 with an upward reset force, and the first end 211 drives the baffle 22 to reset upward together.

[0084] Please refer to the following: Figure 8 , Figure 8 yes Figure 7 The diagram shows the structure of the elastic element 30 and the fixing element 60. The parking lock 1000 also includes the fixing element 60, which is fixed to the first end 211. The first torsion arm 32 is fixed to the first end 211 through the fixing element 60, so that the elastic element 30 is fixed to the first end 211 as a whole.

[0085] Specifically, the fixing member 60 includes a fixing post 61 and a limiting protrusion 62. One end of the fixing post 61 is fixedly connected to the limiting protrusion 62, and the other end of the fixing post 61 is inserted into the first end 211 and fixed thereto. The first torsion arm 32 is bent and is arranged around the circumferential outer wall of the fixing post 61 that is exposed outside the first end 211. The limiting protrusion 62 abuts against the first torsion arm 32 toward the first end 211, so that the first torsion arm 32 abuts against the limiting protrusion 62 and the first end 211, thereby fixing the elastic member 30 as a whole relative to the first end 211 and preventing the elastic member 30 from detaching from the first end 211.

[0086] Among them, the fastener 60 can be a bolt, the fixing post 61 is the stud of the bolt, the stud is threadedly connected to the rotating shaft 21, and the limiting protrusion 62 is the nut of the bolt.

[0087] In some other embodiments, the elastic element 30 may be a leaf spring, one end of which elastically abuts against the mounting base 10 and the other end of which elastically abuts against the first end 211, so as to provide the first end 211 with an upward reset force within the second gap 1012, thereby enabling the stop 20 to be reset upward after the wheel leaves.

[0088] In some embodiments, the position switch 40 is mounted on the mounting base 10, located below the first end 211, with the trigger end 41 opposite to the first end 211. When the first end 211 shifts downward toward the trigger end 41 within the second gap 1012, the first end 211 can trigger the trigger end 41. Alternatively, the position switch 40 is mounted on the first end 211, with the trigger end 41 facing downward and opposite to the mounting base 10. When the first end 211 drives the position switch 40 to shift downward toward the mounting base 10 within the second gap 1012, the mounting base 10 can trigger the trigger end 41. Position switch 40 is mounted on baffle 22. When baffle 22 is in the lowered state, trigger end 41 faces downward and is opposite to mounting base 10. When baffle 22 moves position switch 40 downward toward mounting base 10 within the first gap 1011, mounting base 10 can trigger trigger end 41. Alternatively, position switch 40 is mounted on mounting base 10. Position switch 40 is located below baffle 22 when it is in the lowered state, trigger end 41 faces upward and is opposite to baffle 22. When baffle 22 moves downward toward mounting base 10 within the first gap 1011, baffle 22 can trigger trigger end 41.

[0089] By placing the position switch 40 below or on the first end 211, the position switch 40 is positioned corresponding to the first end 211. On the one hand, when connecting the position switch 40 by wire, the wiring can be directly connected to the position corresponding to the first end 211, avoiding the need to thread the wire through the baffle 22 when the position switch 40 is installed on the baffle 22. This facilitates the wiring of the position switch 40 and simplifies the internal wiring of the parking lock 1000. On the other hand, the vertical downward position change of the first end 211 is greater than the position change of the baffle 22 or the second end, which can ensure that the stop 20 has a better triggering effect on the position switch 40.

[0090] In this way, by placing the position switch 40 on the baffle 22 or below the baffle 22 when it is in a lowered state, the position switch 40 is in a position corresponding to the baffle 22. Thus, the trigger end of the position switch 40 can be triggered when the baffle 20 is pressed down.

[0091] In some embodiments, the position switch 40 is a micro switch or a proximity switch.

[0092] When the position switch 40 is a micro switch, in the non-operating state, the stop 20 does not apply any force to the trigger end 41 of the micro switch, the trigger end 41 is in the extended state, and the internal circuit of the micro switch remains open. If the micro switch is located below the first end 211 or below the stop 22 when it is in the lowered state, when the wheel presses on the stop 20 and forces the stop 20 to move downward, the first end 211 or the stop 22 abuts against the trigger end 41 and applies a force to the trigger end 41, thereby triggering the trigger end 41 and causing it to be in the retracted state, closing the internal circuit of the micro switch; when the wheel leaves the stop 20, the stop 20 resets under the elastic force of the elastic member 30, the force applied by the first end 211 or the stop 22 to the trigger end 41 disappears, the trigger end 41 also resets and is in the extended state, and the internal circuit of the micro switch is disconnected again. If the micro switch is located on the first end 211 or on the baffle 22, when the wheel presses on the stop 20 and forces the stop 20 to move downward, the first end 211 or the baffle 22 drives the micro switch to abut against the mounting base 10. The mounting base 10 applies a reaction force to the trigger end 41, thereby triggering the trigger end 41 and causing the trigger end 41 to be in a retracted state, and the internal circuit of the micro switch is closed. When the wheel leaves the stop 20, the stop 20 is reset under the elastic force of the elastic member 30, the force applied by the mounting base 10 to the trigger end 41 disappears, and the trigger end 41 is also reset and placed in an extended state, and the internal circuit of the micro switch is disconnected again.

[0093] When the position switch 40 is a proximity switch, in the non-operating state, the stop 20 remains in the lowered state, the trigger terminal 41 of the proximity switch does not sense an approaching object, and the internal circuit of the proximity switch remains open. If the proximity switch is located below the first end 211 or below the stop 22 when it is in the lowered state, when the wheel presses on the stop 20 and forces the stop 20 to move downward, the first end 211 or the stop 22 moves closer to the trigger terminal 41. The trigger terminal 41 senses the approach of the first end 211 or the stop 22, thereby triggering the trigger terminal 41, and the internal circuit of the proximity switch closes. When the wheel moves away from the stop 20, the stop 20 resets under the elastic force of the elastic member 30, the first end 211 or the stop 22 moves away from the trigger terminal 41, the trigger terminal 41 does not sense an approaching object, and the internal circuit of the micro switch is disconnected again. If the proximity switch is located on the first end 211 or on the baffle 22, when the wheel presses on the stop 20 and forces the stop 20 to move downward, the first end 211 or the baffle 22 will move the proximity switch toward the mounting base 10. The trigger end 41 will sense the mounting base 10 approaching it and trigger the trigger end 41, thus closing the internal circuit of the proximity switch. When the wheel moves away from the stop 20, the stop 20 will reset under the elastic force of the elastic member 30 and move the proximity switch away from the mounting base 10. The trigger end 41 will not sense the approach of an object, and the internal circuit of the micro switch will be disconnected again.

[0094] like Figure 3 and Figure 4 As shown, in some embodiments, the parking lock 1000 also includes a gyroscope 70 capable of sensing the movement of the stop 20, and the gyroscope 70 is connected to the stop 20.

[0095] Specifically, the gyroscope 70 can be used to detect whether the stop 20, when in the lowered state, makes a downward offset movement within the movement gap, thereby sensing whether a wheel has driven onto the stop 20. Thus, when the position switch 40 fails, the gyroscope 70 can replace the detection function of the position switch 40. The gyroscope 70 can also be used to detect the angle or distance by which the drive assembly drives the stop 20 to rise or fall, to confirm whether the stop 20 has risen or fallen to the correct position. The gyroscope 70 can also be used to detect whether a vehicle has collided with the stop 20 in the raised state. If the stop 20 is impacted, the gyroscope 70 senses the force of the impact and feeds back a signal to the parking lock's electronic control system. The electronic control system determines whether the vehicle evaded payment after the impact based on the force of the impact; if so, it records the evasion information.

[0096] In some embodiments, the gyroscope 70 is mounted at the end of the first end 211 furthest from the baffle 22. This configuration allows for several advantages. First, when connecting the gyroscope 70, the wiring can be directly routed to the end of the first end 211, avoiding the need to thread wires through the baffle 22 when the gyroscope 70 is mounted thereon. This simplifies the wiring of the gyroscope 70 and streamlines the internal wiring of the parking lock 1000. Second, the vertical downward positional change of the first end 211 is greater than that of the baffle 22 or the second end, ensuring that the stop 20 provides a better triggering effect on the gyroscope 70.

[0097] In some embodiments, the end face of the first end 211 is provided with a mounting hole 2111, and the gyroscope 70 is at least partially housed in the mounting hole 2111. This makes the structure of the parking lock 1000 more compact, avoids the need to occupy additional space due to the installation of the gyroscope 70, and the inner wall of the mounting hole 2111 can play a certain limiting role for the gyroscope 70, so that the gyroscope 70 can be stably installed on the first end 211.

[0098] In some other embodiments, the gyroscope 70 is mounted on the baffle 22.

[0099] like Figure 1As shown, in some embodiments, the parking lock 1000 further includes a detection module 80 capable of detecting whether there is a vehicle in the parking space, an electronic control system 90, and a battery 100. The detection module 80 is mounted on the mounting base 10 or the stop 20. The electronic control system 90 is electrically connected to the position switch 40, the drive assembly, the gyroscope 70, and the detection module 80. The battery 100 is electrically connected to the position switch 40, the drive assembly, the gyroscope 70, the detection module 80, and the electronic control system 90.

[0100] The electronic control system 90 is used to receive signals from the position switch 40, the gyroscope 70 and the detection module 80, and to control the drive assembly to drive the stop 20 to rise or fall. The battery 100 is electrically connected to the position switch 40, the drive assembly, the gyroscope 70, the detection module 80 and the electronic control system 90, and the battery 100 is used to supply power to the position switch 40, the drive assembly, the gyroscope 70, the detection module 80 and the electronic control system 90.

[0101] The detection module 80 can be an infrared sensor, an ultrasonic sensor, a geomagnetic sensor, etc.

[0102] like Figure 1 and Figure 4 As shown, in some embodiments, the mounting base 10 further includes a base plate 13, a first cover 14, and a second cover 15, with the first cover 14 and the second cover 15 spaced apart and respectively mounted on the base plate 13. A first connecting seat 11 is mounted on the base plate 13 and housed in the first cover 14, and a second connecting seat 12 is mounted on the base plate 13 and housed in the second cover 15. A stop 20 is located on the base plate 13, and the first end 211 of the rotating shaft 21 extends into the first cover 14 and is rotatably connected to the first connecting hole 111 of the first connecting seat 11, while the second end 212 of the rotating shaft 21 extends into the second cover 15 and is rotatably connected to the second connecting hole 121 of the second connecting seat 12. A stop 22 is located between the first cover 14 and the second cover 15. A position switch 40 is housed in the first cover 14. A drive assembly, an electronic control system 90, and a battery 100 are all housed in the second cover 15. A detection module 80 is mounted on the upper wall of the first cover 14. By setting up the first cover 14 and the second cover 15, the components contained in each cover can be protected to a certain extent, reducing the impact of the usage environment on the normal operation of the parking lock 1000.

[0103] A gap is formed between the baffle 22 and the base plate 13 Figure 4 The first gap 1011 in the illustrated embodiment. The other components below the baffle 22 are the base plate 13, and the first gap 1011 is the gap between the baffle 22 and the base plate 13 when the baffle 22 is in the lowered state.

[0104] The working principle of the parking lock 1000 is illustrated below:

[0105] like Figure 1 As shown, in the initial state, the stop 20 is in a lowered, flat position. The position switch 40 detects whether a vehicle is entering the parking space in real time, while the detection module 80 and the electronic control system 90 are in a dormant state. When a vehicle enters the parking space and its wheels drive onto the stop 20, the wheels force the stop 20 to shift within the movement gap 101. Simultaneously, the position switch 40, connected to the stop 20, senses the shift and converts it into a first electrical signal, which is sent to the electronic control system 90, waking up the electronic control system 90 and the detection module 80. The detection module 80 checks whether the vehicle is in a normal parking position. If the vehicle is in a normal parking position, the detection module 80 sends a second electrical signal to the electronic control system 90. Upon receiving the second electrical signal, the electronic control system 90 controls the drive assembly to raise the stop 20, thereby restricting the vehicle from leaving the parking space. Figure 2 As shown.

[0106] When a vehicle needs to leave the parking space where parking lock 1000 is located, payment can be made by scanning a QR code near the parking space, or by other means, causing the electronic control system 90 to control the drive component 20 to lower, allowing the vehicle to leave the parking space. Figure 1 As shown.

[0107] When the detection module 80 detects that no vehicle is parked in the parking space, the detection module 80 sends a third electrical signal to the electronic control system 90. After receiving the third electrical signal, the electronic control system 90 controls itself and the detection module 80 to re-enter the sleep mode.

[0108] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; under the concept of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of the present invention as described above, which are not provided in detail for the sake of brevity; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
