Description

Technical Field

[0001] The utility model relates to the field of parking locks, in particular to a parking lock. Background Art

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

[0003] Chinese patent CN112796253B discloses a novel flat parking lock, which uses a motor to drive the baffle to flip through a screw rod, a nut slider and a rocker mechanism. In order to realize the linear sliding of the nut slider along the screw rod, a linear slide groove is directly made on the rocker mechanism, and the rocker mechanism is used to prevent the nut slider from rotating. The rocker mechanism and the baffle are coaxially arranged, and the rocker mechanism and the baffle are both flipped around the main axis. This technical solution has the following technical problems: (1) The rocker mechanism and the nut slider rotate relative to each other while moving relative to each other. The linear slide groove not only reduces the overall strength of the rocker mechanism, but also increases the assembly difficulty and transmission complexity between the rocker mechanism and the nut slider. During the long-term use of the parking lock, especially when the baffle is impacted by a vehicle, the rocker mechanism is prone to deformation and fracture; (2) The coaxial arrangement of the rocker mechanism and the baffle results in a large swing amplitude of the rocker mechanism when working, and the motor needs to output a large torque to flip the baffle, which is not conducive to the miniaturization and flattening design of the parking lock.

[0034] In summary, the utility model has the following technical effects:

[0035] 1. The utility model utilizes a transmission mechanism to realize power transmission. The transmission mechanism includes a transmission member, a moving member and a connecting arm. The linear track and the connecting arm are independently arranged. The moving member moves relative to the linear track, and the connecting arm rotates relative to the moving member. The above components constitute a slider connecting rod mechanism. While realizing the movement of the connecting arm, the strength of the connecting arm and the stability of the transmission are guaranteed. The linear track can assist the linear movement of the moving member, and the linear track can limit the vertical displacement of the blocking member when it is in the open state and is subjected to external impact force, that is, the linear track can offset the external impact force, thereby protecting the moving member and avoiding deformation and damage of the moving member. The various components can be integrated on the substrate, so that it is convenient for users to install the parking lock.

[0036] 2. The utility model utilizes the first guide member and the second guide member to realize the sliding connection between the linear track and the moving member, and the relative positions of the linear track, the connecting arm and the moving member are reasonably arranged, and the various components are compactly arranged.

[0037] 3. The support seat and the screw of the utility model have a buffer gap in the axial direction. When the blocker is subjected to external impact force in the open state, the nut and the screw are driven by the connecting arm to move along a linear track within the buffer gap relative to the support seat and the rotating part. The buffer gap is used to provide buffer protection for the blocker, connecting arm, nut, screw and motor, thereby reducing their deformation and damage when subjected to external impact force.

[0038] 4. The utility model arranges the first elastic member in the second connecting hole, so as to prevent the first elastic member from occupying the outer space of the screw rod, thereby ensuring the effective length of the screw rod and facilitating the miniaturization design of the parking lock.

[0039] 5. The central axis of the main shaft of the utility model is offset from the central axis of the connecting shaft. When the driving unit drives the transmission part to move, the transmission part drives the moving part to slide along the linear track. At the same time, the connecting arm follows the moving part to slide along the linear track, and the connecting arm rotates relative to the moving part. The connecting arm drives the blocking part to flip around the main shaft to open or close the blocking part, so that the driving unit can output a smaller torque to drive the blocking part to flip; and the connecting arm has a small movement amplitude during the transmission process, which is conducive to the miniaturization design of the parking lock.

[0040] 6. The utility model utilizes a reinforcing member to strengthen the strength of the connecting shaft and the stopper, thereby alleviating deformation and cracking of the connecting shaft and the stopper. The reinforcing member not only strengthens the strength of the connecting shaft and the stopper, but also realizes the connection between the reinforcing member, the connecting shaft and the stopper.

[0041] 7. The utility model arranges the second elastic member to facilitate the resetting of the blocking member, and the inner diameter of the first mounting hole is larger than the outer diameter of the main shaft. When a vehicle passes through the blocking member in a flat and closed state, the blocking member falls and resets. This action cooperates with other detection units to trigger the drive unit to work, so that the drive unit can be put into sleep mode when no vehicle passes, avoiding the drive unit from being in the on state for a long time, and further saving the power consumption of the drive unit.

[0072] See also Figure 1-Figure 25The utility model discloses a parking lock, comprising: a stopper 10; a driving unit 20; a transmission mechanism 30, wherein the transmission mechanism 30 comprises a transmission member 301, a moving member 302 and a connecting arm 303, wherein the transmission member 301, the moving member 302 and the connecting arm 303 are connected in sequence, wherein the driving unit 20 is connected to the transmission member 301 in a transmission manner, and the connecting arm 303 is connected to the stopper 10 in a rotational manner; a linear rail 40, wherein the linear rail 40 is connected to the moving member 302 in a sliding manner and limits the displacement of the moving member 302 in a direction perpendicular to the sliding direction thereof in the linear rail; a base plate 50, wherein the stopper 10, the driving unit 20, the transmission mechanism 30 and at least one of the linear rails 40 are arranged on the base plate 50; when the driving unit 20 drives the transmission member 301 to move, the transmission member 301 drives the moving member 302 to slide along the linear rail 40, and at the same time drives the connecting arm 303 to slide along the linear rail 40 and rotate relative to the moving member 302, so that the connecting arm 303 drives the blocking member 10 to flip; when the blocking member 10 is subjected to external impact force in the open state, the blocking member 10 drives the connecting arm 303 to move, and the connecting arm 303 drives the moving member 302 to slide relative to the linear rail 40, and the linear rail 40 limits the displacement of the moving member 302 in a direction perpendicular to its sliding direction.

[0073] Preferably, the blocking member 10 , the driving unit 20 , the transmission mechanism 30 and the linear track 40 are all arranged on the base plate 50 .

[0074] More preferably, the baffle 10, the drive unit 20, the transmission mechanism 30 and the linear track 40 are all fixedly connected to the base plate 50. For example, the fixed connection between the above components can be achieved by screw connection, welding, bonding, etc., depending on the actual application scenario, but not limited to this.

[0075] Based on the above structure, the utility model uses a transmission mechanism 30 to achieve power transmission. The transmission mechanism 30 includes a transmission member 301, a moving member 302 and a connecting arm 303. The linear track 40 and the connecting arm 303 are independently arranged. The moving member 302 moves relative to the linear track 40, and the connecting arm 303 rotates relative to the moving member 302. The above components constitute a slider connecting rod mechanism. While realizing the movement of the connecting arm 303, the strength of the connecting arm 303 and the stability of the transmission are guaranteed; the linear track 40 can both assist the moving member 302 in linear motion, and the linear track 40 can also limit the vertical displacement of the blocking member 10 when it is in the open state and subjected to external impact force, that is, the linear track 40 can offset the external impact force, thereby protecting the moving member 302 and avoiding deformation and damage of the moving member 302; the various components can be integrated on the substrate 50, so as to facilitate the user to install the parking lock.

[0076] Specifically, the blocking member 10 is in the shape of a plate, sheet or frame, depending on the actual application scenario, and is not limited to a specific shape so as to be able to block the wheels of the vehicle.

[0077] In the embodiment of the utility model, a linear track 40 is disposed on one side or both sides of the transmission member 301 , and the transmission member 301 and the linear track 40 are parallel to each other.

[0078] Specifically, the transmission member 301 always abuts against the linear track 40 during the movement, and the linear track 40 is used to limit the movement of the moving member 302 so that the moving member 302 can only slide along the linear track 40 .

[0079] Preferably, see Figure 4 , Figure 7 as well as Fig.10 Linear tracks 40 are provided on both sides of the transmission member 301 , and the two linear tracks 40 simultaneously limit the opposite sides of the moving member 302 .

[0080] Further reading Fig.10 , Figure 13-Figure 15 In an embodiment of the utility model, the linear rail 40 is provided with a first guide member 60, and the moving member 302 is provided with a second guide member 304 that slides with the first guide member 60. When the moving member 302 is subjected to external impact force, the first guide member 60 limits the displacement of the second guide member 304 in a direction perpendicular to its sliding direction.

[0081] In the embodiment of the present utility model, the first guide member 60 is a slide groove or a slider, and the second guide member 304 is a slider or a slide groove.

[0082] Preferably, the first guide member 60 is a slide groove, and the second guide member 304 is a slider.

[0083] Preferably, the linear track 40 is plate-shaped or block-shaped, and a slide groove is opened in the middle of the linear track 40 . The slide groove may be a groove or a slot hole, or a notch is opened at the bottom of the linear track 40 .

[0084] More preferably, the linear track 40 is in a plate shape, a notch is provided at the bottom of the linear track 40 , and the transverse cross section of the linear track 40 is in an “L” shape.

[0085] During the movement of the transmission member 301, the slider always abuts against the slide groove. In this way, when the blocking member 10 is subjected to external impact force in the open state, the impact force exerted on the blocking member 10 is transmitted to the connecting arm 303 and simultaneously transmitted to the second guide member 304 of the moving member 302. Since the linear track 40 is set on the substrate 50, the external impact force is transmitted to the linear track 40 and the substrate 50.

[0086] Taking the second guide member 304 as a slider, a notch is provided at the bottom of the linear track 40 for illustration. When the stopper 10 is in the open state and is subjected to an impact force of tilted downward pressure, the impact force on the stopper 10 is transmitted to the slider. According to the force decomposition, the impact force on the stopper 10 is decomposed into a lateral decomposition force and a vertical downward decomposition force. The slider is subjected to a lateral decomposition force and a vertical downward decomposition force respectively. The lateral decomposition force causes the slider to move linearly in the notch, and the vertical downward decomposition force is transmitted to the base plate 50, thereby protecting the transmission member 301 and the moving member 302 from damage by the impact force. When the stopper 10 is subjected to an upward tilted impact force, the vertical upward decomposition force is transmitted to the top of the notch, which will not be described in detail here.

[0087] In addition, if linear rails 40 are provided on both sides of the transmission member 301, the sliders on both sides of the movable member 302 are respectively abutted against the grooves of the linear rails 40 on both sides. When the blocking member 10 is subjected to external impact force, the slider on one side transfers the vertical force to the top of the groove, and according to the balance of force, the slider on the other side transfers the vertical force to the substrate 50, thereby protecting the transmission member 301 and the movable member 302 from damage by the impact force.

[0088] See also Fig.16 In the embodiment of the utility model, the portion of the second guide member 304 close to the moving member 302 is rotatably connected to the connecting arm 303 , and the portion of the second guide member 304 away from the moving member 302 is slidably matched with the first guide member 60 .

[0089] Specifically, the second guide member 304 is a rod-shaped protrusion, and the specific shape of the second guide member 304 is determined according to the specific shape of the first guide member 60 and the specific shape of the connecting arm 303 .

[0090] Based on the above structure, the parking lock of the utility model utilizes the first guide member 60 and the second guide member 304 to realize the sliding connection between the linear track 40 and the moving member 302, and the relative positions of the linear track 40, the connecting arm 303 and the moving member 302 are reasonably arranged, and the various components are compactly arranged.

[0091] In the embodiment of the utility model, the driving unit 20 is a motor, the transmission member 301 is a screw, the moving member 302 is a nut, and the transmission member 301 is threadedly connected to the moving member 302 .

[0092] See also Figure 11-Figure 12In the embodiment of the utility model, the parking lock also includes a rotating member 70, a support seat 80 and a fixed seat 90; a first connecting hole 305 and a second connecting hole 306 are respectively provided at the axial ends of the screw, one axial end of the screw is plugged into the output end of the motor through the first connecting hole 305, and the other axial end of the screw is plugged into the rotating member 70 through the second connecting hole 306; the support seat 80 is sleeved on the outside of the connection position between the screw and the rotating member 70, and the support seat 80 and the screw have a buffer gap in the axial direction, and the fixed seat 90 is sleeved on the outside of the connection position between the screw and the motor; when the blocking member 10 is subjected to external impact force in the open state, the nut and the screw are driven by the connecting arm 303 to move relative to the support seat 80 and the rotating member 70 along the linear track 40 in the buffer gap.

[0093] Based on the above structure, the parking lock support seat 80 and the screw of the utility model have a buffer gap in the axial direction. When the blocking member 10 is subjected to external impact force in the open state, the nut and the screw are driven by the connecting arm 303 to move relative to the support seat 80 and the rotating member 70 along the linear track 40 in the buffer gap. The buffer gap is used to provide buffer protection for the blocking member 10, the connecting arm 303, the nut, the screw and the motor, thereby reducing their deformation and damage when subjected to external impact force.

[0094] Continue reading Figure 11-Figure 12 In an embodiment of the utility model, the parking lock further includes a first elastic member 100 , which is disposed in the second connecting hole 306 , and one axial end of the first elastic member 100 abuts against the screw, and the other axial end of the first elastic member 100 abuts against the rotating member 70 .

[0095] Specifically, the first elastic member 100 is a straight tube spring or rubber.

[0096] Based on the above structure, the parking lock of the present invention sets the first elastic member 100 in the second connecting hole 306 to prevent the first elastic member 100 from occupying the external space of the screw, thereby ensuring the effective length of the screw and facilitating the miniaturization design of the parking lock.

[0097] In the embodiment of the utility model, the first connection hole 305 and the second connection hole 306 are both polygonal holes, the part where the output end of the motor is plugged into the first connection hole 305 is a polygonal shaft, and the part where the rotating member 70 is plugged into the second connection hole 306 is a polygonal shaft.

[0098] That is, the radial cross-section of the part where the output end of the motor is plugged into the first connecting hole 305 is a polygon, and the radial cross-section of the part where the rotating member 70 is plugged into the second connecting hole 306 is a polygon; in this way, through the cooperation of the polygonal hole and the polygonal shaft, the output end of the motor can drive the screw to rotate, and the screw can also move axially relative to the output end of the motor, the rotating member 70 can rotate with the screw, the rotating member 70 can also drive the screw to rotate, and the screw can also move axially relative to the rotating member 70.

[0099] Taking the case where only the first elastic member 100 is provided as an example, the specific movement process of the blocking member 10 when subjected to external impact force is as follows:

[0100] When the blocking member 10 is in the open state and is not subjected to external impact force, under the action of the first elastic member 100 , the screw rod abuts against the fixing seat 90 , and the buffer gap between the screw rod and the supporting seat 80 is at a maximum value.

[0101] When the blocking member 10 is subjected to an external impact force in the open state, for example, when the blocking member 10 is subjected to an external impact force that drives the blocking member 10 to move in the closing direction, Figure 11-Figure 12 , that is, the direction in which the nut is driven to move along the screw to the left, and this direction is set as the first direction; when the blocking member 10 is subjected to an external impact force in the first direction, the external impact force in the first direction is transmitted to the nut through the blocking member 10 and the connecting arm 303, and the nut drives the screw to move along the linear track 40 in the direction close to the rotating member 70, and squeezes the first elastic member 100. During this process, the buffer gap between the screw and the support seat 80 decreases, and the buffer gap between the screw and the fixed seat 90 increases, until the screw impacts the support seat 80. At this time, the buffer gap between the screw and the support seat 80 is 0, and the buffer gap between the screw and the fixed seat 90 is the maximum value.

[0102] When the external impact force in the first direction applied to the baffle 10 disappears, the first elastic member 100 is reset. Under the action of the first elastic member 100, the nut drives the screw to move along the linear track 40 toward the output end of the motor. During this process, the buffer gap between the screw and the support seat 80 increases, and the buffer gap between the screw and the fixed seat 90 decreases until the screw impacts the fixed seat 90. At this time, the buffer gap between the screw and the support seat 80 is the maximum value, and the buffer gap between the screw and the fixed seat 90 is 0.

[0103] It should be noted that an avoidance groove 110 can be set on the rotating member 70 and the output end of the motor to prevent the screw from impacting the rotating member 70 and the output end of the motor when the blocking member 10 is subjected to external impact force; of course, a first elastic member 100 can also be set in the first connecting hole 305, so that when the blocking member 10 is subjected to external impact force in the second direction, buffering can also be achieved, and the second direction refers to the direction opposite to the first direction.

[0104] See also Figure 18-Figure 24 In an embodiment of the utility model, the parking lock also includes a connecting seat 120, the blocker 10 is rotatably connected to the connecting seat 120 through the main shaft 130, the connecting arm 303 is rotatably connected to the blocker 10 through the connecting shaft 140, and the central axis of the main shaft 130 and the central axis of the connecting shaft 140 are offset from each other; when the driving unit 20 drives the transmission member 301 to move, the transmission member 301 drives the moving member 302 to slide along the linear track 40, and at the same time, the connecting arm 303 follows the moving member 302 to slide along the linear track 40, and the connecting arm 303 rotates relative to the moving member 302, and the connecting arm 303 drives the blocker 10 to flip around the main shaft 130 to open or close the blocker 10.

[0105] Based on the above structure, the central axis of the main shaft 130 of the utility model is offset from the central axis of the connecting shaft 140. When the driving unit 20 drives the transmission member 301 to move, the transmission member 301 drives the moving member 302 to slide along the linear track 40. At the same time, the connecting arm 303 follows the moving member 302 to slide along the linear track 40, and the connecting arm 303 rotates relative to the moving member 302. The connecting arm 303 drives the blocking member 10 to flip around the main shaft 130 to open or close the blocking member 10, so that the driving unit 20 can output a small torque to drive the blocking member 10 to flip; refer to Figure 5 as well as Figure 8 It can be seen that the central axis of the main shaft 130 and the central axis of the connecting shaft 140 of the utility model are offset from each other, so that the movement amplitude of the connecting arm 303 is small during the transmission process, which is conducive to the miniaturization design of the parking lock.

[0106] Specifically, the value of the mutual offset between the central axis of the main shaft 130 and the central axis of the connecting shaft 140 is determined according to the actual application scenario, so that the driving unit 20 can easily drive the blocking member 10 to flip.

[0107] Specifically, the connecting seat 120 is provided with the rotating side of the block 10, the connecting seat 120 supports the block 10, and the main shaft 130 and the supporting seat 80 form a hinge structure; in this way, by controlling the number of connecting seats 120 and the installation interval, multi-point support or linear support can be formed for the rotating side of the block 10, which not only increases the strength of the block 10, but also assists the block 10 in flipping, and at the same time can avoid adding components at the end of the block 10 away from the driving unit 20, thereby ensuring the installation space of the parking lock in the axial direction of the block 10.

[0108] Specifically, the connecting seat 120 is fixed on the base plate 50, and the base plate 50 is fixed to the ground by concrete or screws, so that the parking lock is installed; due to the setting of the connecting seat 120, there is a gap between the blocker 10 and the base plate 50, and the gap can accommodate sand and gravel to avoid jamming.

[0109] In the embodiment of the utility model, the connecting arm 303 is rotatably connected to the connecting shaft 140, and the connecting shaft 140 is fixedly connected to the blocking member 10; or, the connecting arm 303 is fixedly connected to the connecting shaft 140, and the connecting shaft 140 is rotatably connected to the blocking member 10.

[0110] See also Figure 6 , Fig. 22 as well as Fig.25 In an embodiment of the utility model, the parking lock also includes a reinforcement member 150, which includes a first support body 1501, a second support body 1502 and a third support body 1503 that are integrally connected; the first support body 1501 abuts against the side of the blocker 10, and a third connecting hole 1504 is provided on the first support body 1501. The connecting shaft 140 passes through the third connecting hole 1504 and is inserted into the upper part of the blocker 10, the second support body 1502 is inserted into the lower part of the blocker 10, and the third support body 1503 is buckled on the back side of the blocker 10.

[0111] Based on the above structure, the parking lock of the utility model utilizes a reinforcement member 150 to strengthen the strength of the connecting shaft 140 and the stopper 10, thereby reducing deformation and cracking of the connecting shaft 140 and the stopper 10. The reinforcement member 150 strengthens the strength of the connecting shaft 140 and the stopper 10 while achieving connection between the reinforcement member 150, the connecting shaft 140 and the stopper 10.

[0112] Specifically, in order to improve the connection stability between the reinforcement 150 and the baffle 10, the portion where the baffle 10 connects to the reinforcement 150 is a solid structure, and corresponding assembly holes for connecting to the connecting shaft 140 and assembly holes for connecting to the second support body 1502 are made in this portion.

[0113] Specifically, the first support body 1501 is extended along the thickness direction of the blocker 10, and the second support body 1502 and the third support body 1503 are extended along the length direction of the blocker 10. In order to further strengthen the connection stability between the reinforcement 150 and the blocker 10, the second support body 1502, the blocker 10 and the third support body 1503 are penetrated along the thickness direction of the blocker 10 by a connecting member, thereby connecting the reinforcement 150 and the blocker 10 together, and the second support body 1502, the blocker 10 and the third support body 1503 are provided with assembly holes for connecting with the connecting member.

[0114] It should be noted that the reinforcement 150 provides wrapping support for the side surfaces and the back surface of the baffle 10, which has a better supporting and reinforcing effect on the baffle 10; and this method can embed the reinforcement 150 into the baffle 10, so that the outer surface of the reinforcement 150 is flush with the outer surface of the baffle 10, preventing the baffle 10 from protruding from the outer surface of the baffle 10, thereby protecting the reinforcement 150.

[0115] See also Figure 18-Figure 22 In an embodiment of the utility model, the parking lock also includes a second elastic member 160, and a first mounting hole 170 and a second mounting hole 180 are provided on the connecting seat 120, and the setting direction of the first mounting hole 170 is perpendicular to the setting direction of the second mounting hole 180; the main shaft 130 is arranged in the first mounting hole 170, and the inner diameter of the first mounting hole 170 is greater than the outer diameter of the main shaft 130; the second elastic member 160 is arranged in the second mounting hole 180, one end of the second elastic member 160 abuts against the main shaft 130, and the other end of the second elastic member 160 abuts against the connecting seat 120 or the substrate 50, so that the main shaft 130 radially abuts against the connecting seat 120.

[0116] Specifically, the second elastic member 160 is a straight tube spring or rubber.

[0117] Based on the above structure, the parking lock of the utility model is provided with a second elastic member 160 to facilitate the resetting of the blocker 10, and the inner diameter of the first mounting hole 170 is larger than the outer diameter of the main shaft 130. There is a movable gap between the main shaft 130 and the connecting seat 120. When a vehicle passes through the blocker 10 in a flat and closed state, the blocker 10 falls and resets. This action cooperates with other detection units 190 to trigger the drive unit 20 to work. In this way, the drive unit 20 can be put into sleep mode when no vehicle passes, thereby avoiding the drive unit 20 being in the on state for a long time, and further saving the power consumption of the drive unit 20.

[0118] Specifically, the first mounting hole 170 may be an oblong hole or an elliptical hole, and the clearance between the main shaft 130 and the support seat 80 for up and down movement is a small clearance, generally 0.5 cm-1 cm, so as not to affect the transmission between the driving unit 20 and the stopper 10 .

[0119] The utility model provides a second elastic member 160 to elastically support the main shaft 130, installs the second elastic member 160 inside the connecting seat 120, and utilizes the second mounting hole 180 to constrain the circumference of the second elastic member 160, so that the second elastic member 160 can maintain directional expansion and contraction, thereby preventing the second elastic member 160 from tilting in its circumferential direction and failing after long-term use, thereby extending the service life of the second elastic member 160.

[0120] It should be noted that the connecting seat 120 is a rigid structure, so that the combined structure of the connecting seat 120 and the second elastic member 160 can provide rigid support for the main shaft 130 while providing elastic support for the main shaft 130, providing a certain buffer for the baffle 10, reducing the impact force of the vehicle, and extending the service life of the baffle 10 to a certain extent.

[0121] Furthermore, the detection unit 190 may be an angle detection unit 190 or a distance sensor. How to use the detection unit 190 to detect the movement of the blocking member 10 and trigger the start and stop of the driving unit 20 is a prior art and will not be described in detail here.

[0122] It should be noted that, due to the provision of the transmission mechanism 30, the baffle 10 can fall and reset when in a flat and closed state without affecting the transmission connection between the drive unit 20 and the transmission mechanism 30; in the above process, the external impact force applied to the baffle 10 in the flat and closed state is an external impact force in a third direction, and the third direction is the direction for driving the second elastic member 160 to be vertically compressed.

[0123] Furthermore, when the stopper 10 falls, since the connecting arm 303 is a rod, the end of the connecting arm 303 close to the stopper 10 may be slightly bent and deformed. When the stopper 10 is reset, the connecting arm 303 is also reset accordingly.

[0124] The specific use process of the utility model is as follows:

[0125] In the initial state, the blocking member 10 is in a flat and closed state, and the vehicle can pass through the parking lock. At this time, the vehicle can enter and exit the parking space freely.

[0126] The driving unit 20 works in the forward direction, and drives the blocking member 10 to flip forward around the main axis 130 through the transmission mechanism 30, the connecting arm 303, and the connecting shaft 140. The blocking member 10 flips to an upright open state, and the blocking member 10 blocks the vehicle, thereby preventing the vehicle from freely entering and exiting the parking space.

[0127] The driving unit 20 works in reverse, and drives the blocking member 10 to flip in reverse around the main axis 130 through the transmission mechanism 30, the connecting arm 303, and the connecting shaft 140. The blocking member 10 flips to a flat closed state, and the vehicle can pass through the parking space lock. At this time, the vehicle can enter and exit the parking space freely.

[0128] It should be noted that, when the barrier 10 is in an upright and open state, the vehicle may impact the barrier 10 from the front or from the back of the barrier 10 in certain circumstances, thereby achieving entry and exit from the parking space; when the vehicle impacts the barrier 10 from the front, it can be considered that the barrier 10 is subjected to an external impact force in a first direction, and the connecting arm 303 transfers the impact force to the nut, so that the nut is subjected to the external impact force in the first direction; when the vehicle impacts the barrier 10 from the back of the barrier 10, it can be considered that the barrier 10 is subjected to an external impact force in a second direction, and the connecting arm 303 transfers the impact force to the nut, so that the nut is subjected to the external impact force in the second direction.

[0129] It should be noted that when the drive unit 20 works in the forward direction, the drive unit 20 rotates clockwise, and when the drive unit 20 works in the reverse direction, the drive unit 20 rotates counterclockwise; or, when the drive unit 20 works in the forward direction, the drive unit 20 rotates counterclockwise, and when the drive unit 20 works in the reverse direction, the drive unit 20 rotates clockwise; it depends on the actual situation and is not limited to this.

[0130] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
