Description

Technical Field

[0001] This utility model relates to the technical field of parking space management equipment, specifically to a parking space lock. Background Technology

[0002] A parking lock is a vehicle locking device with a barrier mechanism. The barrier acts as a blockage between the front and rear wheels of a vehicle, thus locking it in place. Parking locks typically use a DC motor, a reduction gear mechanism, and a worm gear mechanism to raise and lower the barrier. However, the barrier is frequently subjected to vehicle collisions. The force of these collisions is transmitted to the worm gear mechanism, easily causing gear deformation, cracking, or tooth breakage. Furthermore, due to space limitations in parking locks, the size of the worm gear mechanism is restricted, making it difficult to improve its strength. Consequently, the reliability of existing parking locks is not high. Utility Model Content

[0003] In view of this, the present invention provides a parking space lock to solve the problem of insufficient reliability of existing parking space locks.

[0004] This utility model provides a parking space lock, including:

[0005] A base on which a rotating shaft is rotatably mounted;

[0006] A baffle is fixedly connected to a rotating shaft to facilitate its rotation under the drive of the rotating shaft.

[0007] The hydraulic strut assembly includes a cylinder body, a hydraulic rod, an oil pump, and an oil reservoir. The cylinder body is hinged to the base, and the hydraulic rod is slidably sealed to the inner wall of the cylinder body. The oil reservoir is connected to the rodless chamber of the cylinder body through the oil pump and the return oil channel. The return oil channel is equipped with a pressure relief valve and has a blocked state and an open state.

[0008] The hydraulic rod is connected to the rotating shaft via the connector, so as to drive the rotating shaft to rotate around its own axis.

[0009] In one alternative embodiment, the oil pump is a plunger pump, and a first motor is provided on the base. The first motor is connected to the plunger of the plunger pump through a transmission mechanism to drive the plunger to reciprocate.

[0010] In one optional embodiment, the transmission mechanism is a three-bar linkage, including a first link, a second link, and a third link that are hinged to each other at their ends. The first end of the first link is hinged to the plunger pump, and the tail end of the third link is fixedly connected to the rotational output end of the first motor. The first link is connected to the plunger so as to enable the first motor to drive the plunger to reciprocate through the transmission mechanism.

[0011] In one alternative embodiment, the pressure relief valve includes a ball and a bolt, the ball being adapted to block the return oil passage when the bolt is tightened.

[0012] In one alternative embodiment, a retaining spring is provided between the ball and the bolt.

[0013] In one alternative embodiment, the parking lock further includes a second motor fixedly mounted on the base, the rotation output end of the second motor being connected to the bolt by a coupling, and the second motor being adapted to drive the bolt to rotate around its own axis.

[0014] In one alternative implementation, the coupling includes a universal joint coupling.

[0015] In one alternative implementation, the parking lock further includes a vehicle detection component adapted to detect whether a vehicle is present in the parking space, the vehicle detection component being electrically connected to a first motor and a second motor.

[0016] In one alternative implementation, the connector includes a crank or a strip plate.

[0017] In one alternative embodiment, a shaft base is fixedly mounted on the base, and the rotating shaft is rotatably mounted on the shaft base.

[0018] The technical solution of this utility model has the following advantages:

[0019] 1. The parking lock provided by this utility model uses an oil pump to deliver hydraulic oil to the rodless chamber to push out a hydraulic rod, so that the hydraulic rod drives the baffle to flip up or flip down through the connecting parts and the rotating shaft. When the baffle is hit by a vehicle, the hydraulic mechanism formed by the hydraulic rod and the hydraulic rod is not jammed, so it can play a buffering role. The parking lock is not prone to structural damage, thereby improving the reliability of the parking lock.

[0020] 2. The parking lock provided by this utility model drives the plunger to move back and forth through the first motor and transmission mechanism to send the hydraulic oil pump into the rodless chamber, thereby saving manpower.

[0021] 3. The parking lock provided by this utility model is equipped with a retaining spring. When the external force on the hydraulic rod exceeds the threshold, the spring is compressed, and the ball moves to a position with a gap between it and the return oil channel, so that the hydraulic oil flows back to the oil storage chamber, the hydraulic rod retracts, and the baffle flips and falls, thereby realizing the overload protection function and avoiding structural damage to the parking lock.

[0022] 4. The parking lock provided by this utility model has a second motor that drives the bolt to rotate through a coupling, so that the pressure relief valve can switch between the open and unlocked states, thereby saving manpower.

[0023] 5. The parking lock provided by this utility model uses a universal joint coupling, which can reduce the restrictions on the setting position and angle of the second motor, and helps to make the internal structure of the parking lock more compact and reduce the overall size of the parking lock.

[0024] 6. The parking lock provided by this utility model detects the presence of a vehicle by setting a vehicle detection component, and controls the start, stop, forward and reverse rotation of the first motor and the second motor according to the detection result, thereby improving the automation level of the parking lock.

[0025] 7. The parking lock provided by this utility model has a shaft base for supporting the rotating shaft to rotate around its own axis, thereby improving the rotational stability of the rotating shaft. Attached Figure Description

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] The following is combined Figures 1 to 4 The following describes embodiments of the present invention.

[0035] According to an embodiment of the present invention, a parking space lock is provided, comprising:

[0036] Base 1, on which a rotating shaft 2 is rotatably mounted;

[0037] The baffle 3 is fixedly connected to the rotating shaft 2 so as to be able to flip under the drive of the rotating shaft 2;

[0038] The hydraulic strut assembly includes a cylinder body 41, a hydraulic rod 42, an oil pump 43, and an oil storage chamber. The cylinder body 41 is hinged to the base 1. The hydraulic rod 42 is slidably sealed to the inner wall of the cylinder body 41. The oil storage chamber is connected to the rodless chamber of the cylinder body 41 through the oil pump 43 and the return oil channel. A pressure relief valve is provided on the return oil channel, and it has a blocked state of blocking the return oil channel and an open state of opening the return oil channel.

[0039] Connector 5, hydraulic rod 42 is connected to rotating shaft 2 through connector 5, so as to drive rotating shaft 2 to rotate around its own axis.

[0040] In the parking lock provided in this embodiment, the oil pump 43 pumps hydraulic oil into the rodless chamber to push out the hydraulic rod 42, so that the hydraulic rod 42 drives the baffle 3 to flip up or flip down through the connector 5 and the rotating shaft 2. When the baffle 3 is hit by a vehicle, since the hydraulic rod 42 and the hydraulic rod 42 are not stuck, the hydraulic mechanism they form can play a buffering role, and the parking lock is not prone to structural damage, thereby improving the reliability of the parking lock.

[0041] Specifically, the base 1 is fixedly installed at the parking space, the baffle 3 is installed on the horizontal side of the base 1, the axis of the rotating shaft 2 is set in the horizontal direction and is fixedly connected to one side edge of the baffle 3, and the rotating shaft 2 rotates around its own axis to drive the baffle 3 to flip. The connecting piece 5 is fixedly connected to the rotating shaft 2, and the hydraulic rod 42 extends or retracts relative to the inner cavity of the cylinder 41, and drives the rotating shaft 2 to rotate around its own axis through the connecting piece 5. The end of the cylinder 41 away from the hydraulic rod 42 is hinged to the base 1, and the end of the hydraulic rod 42 away from the cylinder 41 is hinged to the connecting piece 5, so as to meet the angle change between the cylinder 41 and the hydraulic rod 42 relative to the base 1 and the connecting piece 5 during the extension and retraction of the hydraulic rod 42.

[0042] When the pressure relief valve is adjusted to the blocked state, the hydraulic oil in the oil reservoir is pumped to the rodless chamber by the oil pump 43, thereby pushing out the hydraulic rod 42 and driving the baffle 3 to flip until the baffle 3 reaches the preset angle. When it is necessary to unlock the parking lock, the pressure relief valve is adjusted to the open state, and the baffle 3 flips and falls under its own gravity, driving the hydraulic rod 42 to retract. The hydraulic oil is compressed by the hydraulic rod 42 and returns to the oil reservoir through the return oil channel.

[0043] In one embodiment, combined Figure 1 and Figure 2 As shown, the oil pump 43 is a plunger pump, and the base 1 is equipped with a first motor 6. The first motor 6 is connected to the plunger 431 of the plunger pump through a transmission mechanism 7, so as to drive the plunger 431 to reciprocate.

[0044] The parking lock provided in this embodiment drives the plunger 431 to reciprocate through the first motor 6 and the transmission mechanism 7 to send hydraulic oil to the rodless chamber, thereby saving manpower.

[0045] In one embodiment, combined Figures 1 to 3 As shown, the transmission mechanism 7 is a three-bar linkage mechanism, including a first link 71, a second link 72, and a third link 73 that are hinged to each other at their ends. The first end of the first link 71 is hinged to the plunger pump, and the tail end of the third link 73 is fixedly connected to the rotation output end of the first motor 6. The first link 71 is connected to the plunger 431 to enable the first motor 6 to drive the plunger 431 to reciprocate through the transmission mechanism 7.

[0046] Specifically, the third link 73 is adapted to rotate around the axis of the output end of the first motor 6. The hinge axis of the second link 72 and the first link 71 is parallel to the rotor axis of the first motor 6. The hinge axis of the first link 71 and the second link 72 is parallel to the rotor axis of the first motor 6. The hinge axis of the first end of the first link 71 and the plunger pump is parallel to the rotor axis of the first motor 6. The reciprocating movement direction of the plunger 431 is perpendicular to the rotor axis of the first motor 6. The end of the plunger 431 away from the pump body is movably fixedly connected to the area between the two ends of the first link 71, so that during the rotation of the first link 71 around its hinge axis with the plunger pump, the plunger 431 reciprocates under the drive of the first link 71, thereby pumping the hydraulic oil in the oil storage chamber to the rodless chamber.

[0047] In one embodiment, combined Figure 1 As shown, the pressure relief valve includes a ball and a bolt 8, the ball being adapted to block the return oil passage under the tightening action of the bolt 8.

[0048] Specifically, the return oil channel has different inner diameters. The ball is movably positioned within the return oil channel, having both a blocking position that fits against the inner wall of the return oil channel and a movable position with a gap between it and the inner wall. By rotating bolt 8, the ball is moved and placed in the blocking position, at which point the pressure relief valve is in a blocked state. By rotating bolt 8 in the opposite direction to move it away from the ball, the ball returns to its movable position under the pressure of hydraulic oil, at which point the pressure relief valve is in an open state.

[0049] In one embodiment, a retaining spring is provided between the ball and the bolt 8.

[0050] The parking lock provided in this embodiment is equipped with a retaining spring. When the external force on the hydraulic rod 42 exceeds a threshold, the spring is compressed, the ball moves to a position with a gap between it and the return oil channel, so that the hydraulic oil flows back to the oil storage chamber, the hydraulic rod 42 retracts, and the baffle 3 flips and falls, thereby realizing the overload protection function and avoiding structural damage to the parking lock.

[0051] Specifically, when the pressure relief valve is in the blocked state, the retaining spring is compressed. When the external force on the baffle 3 exceeds the threshold, the pressure of the hydraulic oil in the rodless chamber increases, pushing the ball to the movable position. At this time, the retaining spring is further compressed, and the hydraulic oil can return to the oil storage chamber through the gap between the ball and the return oil channel. The baffle 3 drives the hydraulic rod 42 to retract, preventing damage to the baffle 3, thereby achieving the overload protection function. Specifically, when the pressure relief valve is in the blocked state, the greater the compression of the retaining spring or the greater its structural strength, the greater the threshold of external force that the baffle 3 can withstand.

[0052] In one embodiment, combined Figure 1 and Figure 2As shown, the parking lock also includes a second motor 9 fixedly mounted on the base 1. The rotation output end of the second motor 9 is connected to the bolt 8 by a coupling 10. The second motor 9 is adapted to drive the bolt 8 to rotate around its own axis.

[0053] In the parking lock provided in this embodiment, the second motor 9 drives the bolt 8 to rotate through the coupling 10, so that the pressure relief valve switches between the open state and the unlocked state, thereby saving manpower.

[0054] Combination Figure 4 As shown, the hydraulic strut assembly, connector 5, first motor 6 and second motor 9 are provided with a protective shell 13 to provide protection and dust protection, thereby improving the reliability of the parking lock.

[0055] In one embodiment, combined Figure 1 As shown, coupling 10 includes a universal joint coupling.

[0056] The parking lock provided in this embodiment uses a universal joint coupling, which reduces the restrictions on the setting position and angle of the second motor 9, making the internal structure of the parking lock more compact and reducing the overall size of the parking lock.

[0057] Specifically, the coupling 10 can be a straight rod or a universal joint coupling. When the coupling 10 is a straight rod, the rotation axis of the output end of the second motor 9 needs to be aligned with the axis of the bolt 8. When the coupling 10 is a universal joint coupling, the position and angle of the second motor 9 have a wider range of options, which helps to improve the flexibility of the second motor 9 and makes the internal structure of the parking lock more compact according to actual needs.

[0058] In one embodiment, as shown in the figure, the parking lock further includes a vehicle detection component 11 adapted to detect whether there is a vehicle in the parking space, the vehicle detection component 11 being electrically connected to a first motor 6 and a second motor 9.

[0059] The parking lock provided in this embodiment detects whether there is a vehicle by setting a vehicle detection component 11, and controls the start, stop and forward / reverse rotation of the first motor 6 and the second motor 9 according to the detection result, thereby improving the automation level of the parking lock.

[0060] Specifically, the vehicle detection component 11 includes a main controller, a vehicle detector, and an angle sensor. The vehicle detector is used to detect whether there is a vehicle in the parking space. Since the vehicle detector is existing technology, it will not be described in detail here. The angle sensor is used to detect the lifting angle of the baffle 3. The main controller is electrically connected to the first motor 6, the second motor 9, the vehicle detector, and the angle sensor.

[0061] During the locking process, the main controller, based on remote commands or vehicle detector results, controls the first motor 6 and the second motor 9 to raise the baffle 3. When the angle of the baffle 3 reaches a set value, the first motor 6 stops driving. During the unlocking process, the main controller, based on remote commands or vehicle detector results, controls the second motor 9 to drive the pressure relief valve to release pressure. The baffle 3 automatically descends under its own weight. When the baffle 3 reaches a set value, the second motor 9 stops driving.

[0062] In one embodiment, combined Figure 1 and Figure 2 As shown, connector 5 includes a crank or a strip plate.

[0063] Specifically, the two ends of the connector 5 are connected to the rotating shaft 2 and the hydraulic rod 42 respectively. The connector 5 is adapted to rotate around the axis of the rotating shaft 2. The hinge axis of the hydraulic rod 42 and the connector 5 is parallel to the axis of the rotating shaft 2.

[0064] In one embodiment, combined Figure 1 and Figure 2 As shown, a shaft base 12 is fixedly mounted on the base 1, and a rotating shaft 2 is rotatably mounted on the shaft base 12.

[0065] The parking lock provided in this embodiment has a shaft base 12 for supporting the rotating shaft 2 to rotate around its own axis, thereby improving the rotational stability of the rotating shaft 2.

[0066] Obviously, the above embodiments are merely examples for clear illustration and are not intended to limit the implementation. Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope defined by the present invention.
