Parking space lock

Abstract

Disclose parking space lock. [Solution] A parking space lock in one embodiment includes a stopper member, a drive unit, a transmission mechanism, and a straight rail. When the transmission member is driven to move by the drive unit, the transmission member causes the moving member to slide along the straight rail, and at the same time, the connecting arm slides along the straight rail and rotates relative to the moving member, causing the stopper member to be inverted by the connecting arm. When the stopper member is in the open state and receives an external impact force, the stopper member moves the connecting arm, the connecting arm causes the moving member to slide against the straight rail, and the straight rail limits the displacement of the moving member in a direction perpendicular to its sliding direction.

Description

[Technical field]

[0001] The present application relates to the field of parking space locks, and in particular to parking space locks. [Background technology]

[0002] A parking space lock is a mechanical device that is mounted on the ground and is used to prevent unauthorized occupation of a parking space by others or to prevent a vehicle from leaving the parking space.

[0003] A new type of flat parking space lock in the related art adopts a technical aspect in which the stopper plate is reversed by a motor via a screw, a nut slider, and a rocker arm mechanism, and in order to realize linear sliding of the nut slider along the screw, a linear slide groove is directly formed in the rocker arm mechanism, the rocker arm mechanism is used to avoid rotation of the nut slider member, the rocker arm mechanism and the stopper plate are arranged coaxially, and both the rocker arm mechanism and the stopper plate are reversed around the main shaft. This technical aspect has the following technical problems. (1) The rocker arm mechanism and the nut slider rotate relative to each other and at the same time move relative to each other, and the linear slide groove not only reduces the overall strength of the rocker arm mechanism, but also makes it difficult to attach the rocker arm mechanism and the nut slider and increases the complexity of the transmission. During long-term use of the parking space lock, especially when the stopper plate is subjected to impact from the vehicle, the rocker arm mechanism becomes more susceptible to deformation and breakage. (2) Because the rocker arm mechanism and the stopper plate are arranged coaxially, the rocker arm mechanism swings larger during operation, and in order to reverse the stopper plate, a large torque needs to be output from the motor, which is disadvantageous in designing a compact and flatter parking space lock.

Effect of the Invention

[0018] As a result of the above, the present application has the following technical effects. 1. The present application provides a power transmission mechanism, which includes a transmission member, a movable member and a connecting arm, the straight rail and the connecting arm being provided independently of each other, the movable member moving relative to the straight rail, and the connecting arm rotating relative to the movable member, and a slider link mechanism is formed by the above components, which realizes the movement of the connecting arm while ensuring the strength of the connecting arm and the stability of the transmission. The straight rail can support the linear movement of the movable member, while the straight rail can limit the vertical displacement of the stopper member when it is subjected to an external impact force in the open state, i.e., the straight rail can counteract the external impact force, thereby protecting the movable member and avoiding deformation and damage to the movable member. 2. In the present application, the sliding contact between the straight rail and the movable member is realized by using the first guide member and the second guide member, and the relative positions of the straight rail, the connecting arm and the movable member are set rationally, and each part is arranged compactly. 3. In the present application, a buffer gap is provided in the axial direction between the support seat and the screw rod. When the stopper member is in the open state and receives an external impact force, the connecting arm moves the nut and the screw rod together with the support seat and the rotating member along a straight rail within the buffer gap. The buffer gap is used to buffer and protect the stopper member, connecting arm, nut, screw rod and motor, and reduces deformation and damage to them when they receive an external impact force. 4. By arranging the first elastic member in the second connecting hole, the present application can avoid the first elastic member from occupying the external space of the threaded rod, ensure the effective length of the threaded rod, and is advantageous for the design of a compact parking space lock. 5. In the present application, the central axis of the main shaft and the central axis of the connecting shaft are offset from each other. When the transmission member is driven to move by the driving unit, the transmission member causes the movable member to slide along the straight rail, and at the same time, the connecting arm slides along the straight rail together with the movable member and rotates relative to the movable member. The connecting arm causes the stopper member to rotate around the main shaft, thereby opening and closing the stopper member. Therefore, when a small torque is output from the driving unit, the stopper member can be rotated, and the movement range of the connecting arm during transmission is small, which is advantageous for realizing the design of a compact parking space lock. 6. In the present application, a reinforcing member is used to reinforce the strength of the connecting shaft and the stopper member, thereby reducing deformation and cracking of the connecting shaft and the stopper member, and the strength of the connecting shaft and the stopper member is reinforced by the reinforcing member, while at the same time realizing the connection between the reinforcing member and the connecting shaft and the stopper member. 7. The present application provides a second elastic member, which is advantageous for the return of the stopper 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 stopper member in a flat, closed state, the stopper member falls and returns, and in response to this action, another detection unit can trigger the operation of the drive unit. In this way, a function can be realized such as putting the drive unit to sleep when no vehicle is passing, which prevents the drive unit from being in an activated state for a long period of time and further saves power consumption of the drive unit.

[0021] 1 to 25, the present application discloses a parking space lock, the parking space lock including a stopper member 10, a drive unit 20, a transmission mechanism 30 including a transmission member 301, a moving member 302, and a connecting arm 303, in which the transmission member 301, the moving member 302, and the connecting arm 303 are connected in sequence, the drive unit 20 is connected to the transmission member 301, and the connecting arm 303 is connected to the stopper member 10 in a rotational manner, and a straight rail 40 that is in sliding contact with the moving member 302 and limits the displacement of the moving member 302 in a direction perpendicular to the sliding direction thereof within the straight rail, the drive unit When the transmission member 301 is driven by 20 to move, the transmission member 301 causes the movable member 302 to slide along the straight rail 40, and at the same time causes the connecting arm 303 to slide along the straight rail 40 and rotate relative to the movable member 302, causing the stopper member 10 to be inverted by the connecting arm 303.When the stopper member 10 is subjected to an external impact force in the open state, the stopper member 10 moves the connecting arm 303, and the connecting arm 303 causes the movable member 302 to slide relative to the straight rail 40, and the straight rail 40 limits the displacement of the movable member 302 in a direction perpendicular to its sliding direction.

[0022] Based on the above structure, the present application realizes power transmission by using the transmission mechanism 30, the transmission mechanism 30 includes a transmission member 301, a moving member 302 and a connecting arm 303, the straight rail 40 and the connecting arm 303 are provided independently of each other, the moving member 302 moves relative to the straight rail 40, and the connecting arm 303 rotates relative to the moving member 302, a slider link mechanism is formed by the above parts, the movement of the connecting arm 303 is realized, and at the same time, the strength of the connecting arm 303 and the stability of transmission are guaranteed, the straight rail 40 can support the linear movement of the moving member 302, while the straight rail 40 can limit the vertical displacement of the stopper member 10 when it is subjected to an external impact force in the open state, that is, the straight rail 40 can counteract the external impact force, as a result, the moving member 302 is protected and deformation and damage of the moving member 302 is avoided.

[0023] Specifically, the stopper member 10 may be in the form of a plate, a sheet or a frame, depending on the actual application scene, and is not limited to a specific shape as long as it can fulfill the role of blocking the wheels of the vehicle.

[0024] Specifically, the stopper member 10 may be directly attached to the ground, or the stopper member 10 may be attached to the ground via the base plate 50. The specific mounting method of the stopper member 10 is determined according to the actual situation and is not limited thereto. When the base plate 50 is adopted, each component can be integrated into the base plate 50, which makes it easy for the user to install the parking space lock.

[0025] In the embodiment of the present application, the linear rail 40 is provided on one or both sides of the transmission member 301, and the transmission member 301 and the linear rail 40 are parallel to each other.

[0026] Specifically, the transmission member 301 is always in contact with the straight rail 40 during movement, and the straight rail 40 is used to restrict the occurrence of rotation of the moving member 302, so that the moving member 302 can slide only along the straight rail 40.

[0027] Preferably, referring to Figs. 4 and 7, a straight rail 40 is provided on each side of the transmission member 301, and the two straight rails 40 simultaneously restrict the positions of both opposing sides of the moving member 302.

[0028] 10 and 14, in an embodiment of the present application, a first guide member 60 is provided on the straight rail 40, and a second guide member 304 that slides in conjunction with the first guide member 60 is provided on the movable member 302, and when the movable member 302 is subjected to an 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.

[0029] In the embodiment of the present application, 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.

[0030] Preferably, the first guide member 60 is a slide groove, and the second guide member 304 is a slider.

[0031] Preferably, the straight rail 40 is plate-shaped or block-shaped, and the middle of the straight rail 40 has a slide groove, which may be a groove or a slot, or the bottom of the straight rail 40 has a notch.

[0032] More preferably, the straight rail 40 is plate-shaped, a notch is formed at the bottom of the straight rail 40, and the cross section of the straight rail 40 is "L" shaped.

[0033] During the movement of the transmission member 301, the slider is always in contact with the slide groove; thus, when the stopper member 10 is subjected to an impact force from the outside world in the open state, the impact force received by the stopper member 10 is transmitted to the connecting arm 303 and at the same time to the second guide member 304 of the movable member 302; since the straight rail 40 is mounted on the ground or the base plate 50, the impact force from the outside world can be transmitted to the straight rail 40 and the ground, or the impact force from the outside world can be transmitted to the straight rail 40, the base plate 50 and the ground.

[0034] An example is given in which the second guide member 304 is a slider and a notch is opened at the bottom of the straight rail 40. When the stopper member 10 receives an impact force pushing it diagonally downward in the open state, the impact force received by the stopper member 10 is transmitted to the slider, and the impact force received by the stopper member 10 is decomposed into a horizontal decomposition force and a vertical downward decomposition force due to the force decomposition, and the slider receives the horizontal decomposition force and the vertical downward decomposition force respectively, and the horizontal decomposition force causes the slider to move linearly along the notch, and the vertical downward decomposition force is transmitted to the base plate 50 or the ground, so that the transmission member 301 and the moving member 302 are protected from damage due to the impact force. When the stopper member 10 receives an impact force tilting upward, the vertical upward decomposition force is transmitted to the top of the notch, which will not be described again here.

[0035] Furthermore, if a straight rail 40 is provided on both sides of the transmission member 301, the sliders on both sides of the movable member 302 will abut against the notches of the straight rails 40 on both sides, and when the stopper member 10 is subjected to an external impact force, the slider on one side will transmit the vertical force to the top of the notch, and due to the balance of forces, the slider on the other side will transmit the vertical force to the base plate 50 or the ground. As a result, the transmission member 301 and the movable member 302 are protected from damage due to the impact force.

[0036] 16, in this embodiment, a portion of the moving member 302 in the second guide member 304 is pivotally connected to a connecting arm 303, and a portion of the second guide member 304 remote from the moving member 302 slides into engagement with the first guide member 60. As shown in FIG.

[0037] Specifically, the second guide member 304 is a rod-shaped convex portion, 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 .

[0038] Based on the above structure, in the present application, the first guide member 60 and the second guide member 304 are utilized to realize sliding contact between the straight rail 40 and the movable member 302, and the relative positions of the straight rail 40, the connecting arm 303 and the movable member 302 are set rationally, and each component is arranged compactly.

[0039] In the embodiment of the present application, the driving unit 20 is a motor, the transmission member 301 is a threaded rod, the moving member 302 is a nut, and the transmission member 301 is screwed with the moving member 302 .

[0040] 11-12, in an embodiment of the present application, the parking space lock further includes a rotating member 70, a support seat 80, and a fixed seat 90, and a first connecting hole 305 and a second connecting hole 306 are provided at both axial ends of the threaded rod, respectively. One axial end of the threaded rod is inserted into the output end of the motor through the first connecting hole 305, and the other axial end of the threaded rod is inserted into the rotating member 70 through the second connecting hole 306. The support seat 80 is fitted outside the connection position between the threaded rod and the rotating member 70, and a buffer gap is provided between the support seat 80 and the threaded rod, and the fixed seat 90 is fitted outside the connection position between the threaded rod and the motor. When the stopper member 10 is in an open state and receives an impact force from the outside, the connecting arm 303 moves the nut and the threaded rod together with the support seat 80 and the rotating member 70 within the buffer gap along the straight rail 40.

[0041] Based on the above structure, the present application provides an axial buffer gap between the support seat 80 and the screw rod, and when the stopper member 10 is in an open state and receives an external impact force, the connecting arm 303 moves both the nut and the screw rod within the buffer gap along the straight rail 40 relative to the support seat 80 and the rotating member 70, and the buffer gap is used to buffer and protect the stopper member 10, connecting arm 303, nut, screw rod and motor, reducing deformation and damage to them when they receive an external impact force.

[0042] Continuing to refer to Figures 11 and 12, in an embodiment of the present application, the parking space lock further includes a first elastic member 100, the first elastic member 100 is arranged in the second connecting hole 306, and one axial end of the first elastic member 100 abuts against the screw rod, and the other axial end of the first elastic member 100 abuts against the pivot member 70.

[0043] Specifically, the first elastic member 100 is a straight tube spring or rubber.

[0044] Based on the above structure, the present application arranges the first elastic member 100 in the second connecting hole 306, thereby preventing the first elastic member 100 from occupying the external space of the threaded rod, ensuring the effective length of the threaded rod, and favoring the design of a compact parking space lock.

[0045] In the embodiment of the present application, the first connecting hole 305 and the second connecting hole 306 are both polygonal holes, the portion where the output end of the motor is inserted into the first connecting hole 305 is a polygonal shaft, and the portion where the rotating member 70 is inserted into the second connecting hole 306 is a polygonal shaft.

[0046] That is, the radial cross section of the portion where the output end of the motor is inserted into the first connecting hole 305 is polygonal, and the radial cross section of the portion where the rotating member 70 is inserted into the second connecting hole 306 is polygonal. In this way, by cooperating the polygonal hole and the polygonal shaft, the screw rod can be rotated by the output end of the motor, while the screw rod can also move axially relative to the output end of the motor, and the rotating member 70 can rotate together with the screw rod, and the screw rod can be rotated by the rotating member 70, while the screw rod can also move axially relative to the rotating member 70.

[0047] Taking an example in which only the first elastic member 100 is provided, the specific movement process of the stopper member 10 when it receives an external impact force is as follows. When the stopper member 10 is in an open state and is not subjected to external impact force, under the action of the first elastic member 100, the threaded rod abuts against the fixed seat 90, and the buffer gap between the threaded rod and the support seat 80 is at a maximum value.

[0048] When the stopper member 10 is subjected to an external impact force in the open state, for example, the stopper member 10 receives an external impact force that moves the stopper member 10 in the closing direction, see Figures 11 and 12, that is, an external impact force in a direction that moves the nut to the left along the screw rod (this direction is referred to as the first direction), the external impact force in the first direction is transmitted to the nut via the stopper member 10 and the connecting arm 303, and the nut moves the screw rod along the straight rail 40 in a direction approaching the rotating member 70, pressing the first elastic member 100, and during this process, the buffer gap between the screw rod and the support seat 80 decreases and the buffer gap between the screw rod and the fixed seat 90 increases, and when the screw rod impacts the support seat 80, the buffer gap between the screw rod and the support seat 80 becomes 0 and the buffer gap between the screw rod and the fixed seat 90 becomes a maximum value.

[0049] When the external impact force in the first direction received by the stopper member 10 disappears, the first elastic member 100 returns to its original position, and under the action of the first elastic member 100, the nut moves the threaded rod along the straight rail 40 in the direction approaching the output end of the motor. In this process, the buffer gap between the threaded rod and the support seat 80 increases, and the buffer gap between the threaded rod and the fixed seat 90 decreases. When the threaded rod impacts the fixed seat 90, the buffer gap between the threaded rod and the support seat 80 reaches its maximum value, and the buffer gap between the threaded rod and the fixed seat 90 becomes zero.

[0050] It should be noted that the rotating member 70 and the output end of the motor may be provided with an escape groove 110, so that when the stopper member 10 receives an external impact force, the threaded rod will not impact the rotating member 70 and the output end of the motor. Of course, the first connecting hole 305 may also be provided with a first elastic member 100, so that when the stopper member 10 receives an external impact force in a second direction, the buffering can also be realized, and the second direction is opposite to the first direction.

[0051] 18 to 24, in an embodiment of the present application, the parking space lock further includes a connecting seat 120, the stopper member 10 is rotatably connected to the connecting seat 120 via the main shaft 130, and the connecting arm 303 is rotatably connected to the stopper member 10 via the connecting shaft 140, the central axis of the main shaft 130 and the central axis of the connecting shaft 140 are misaligned with each other, and when the transmission member 301 is driven and moved by the drive unit 20, the transmission member 301 causes the moving member 302 to slide along the straight rail 40, and at the same time, the connecting arm 303 slides along the straight rail 40 together with the moving member 302 and the connecting arm 303 is rotated relative to the moving member 302, and the stopper member 10 is reversed around the main shaft 130 by the connecting arm 303, thereby opening and closing the stopper member 10.

[0052] Based on the above structure, in the present application, the central axis of the main shaft 130 and the central axis of the connecting shaft 140 are offset from each other. When the transmission member 301 is driven by the driving unit 20 to move, the transmission member 301 causes the moving member 302 to slide along the straight rail 40, and at the same time, the connecting arm 303 slides along the straight rail 40 together with the moving member 302, and the connecting arm 303 rotates relative to the moving member 302. The connecting arm 303 rotates the stopper member 10 around the main shaft 130, thereby opening and closing the stopper member 10. Therefore, when a small torque is output from the driving unit 20, the stopper member 10 can be rotated. As can be seen by referring to FIG. 5 and FIG. 8, in the present application, the central axis of the main shaft 130 and the central axis of the connecting shaft 140 are offset from each other, so that the movement range of the connecting arm 303 during transmission is reduced, which is advantageous for realizing a compact design of the parking space lock.

[0053] Specifically, the value by which the central axis of the main shaft 130 and the central axis of the connecting shaft 140 are offset from each other is determined according to the actual application scene, and it is sufficient if the drive unit 20 can easily reverse the stopper member 10.

[0054] Specifically, the connecting seat 120 is provided on the rotating side of the stopper member 10, the connecting seat 120 supports the stopper member 10, and the main shaft 130 and the support seat 80 form a hinge structure. In this manner, by controlling the quantity and mounting intervals of the connecting seats 120, a multi-point support or line support can be formed for the rotating side of the stopper member 10, which can assist the stopper member 10 in reversing while increasing the strength of the stopper member 10, while avoiding an increase in the number of parts at the end of the stopper member 10 far from the drive unit 20, and ensuring the mounting space of the parking space lock in the axial direction of the stopper member 10.

[0055] Specifically, the connecting seat 120 is fixed to the base plate 50 or directly to the ground, and the base plate 50 is fixed to the ground by concrete or screws, thereby installing the parking space lock. In an embodiment that does not use the base plate 50, the connecting seat 120 may be directly fixed to the ground by concrete or screws, thereby installing the parking space lock. Since the connecting seat 120 is provided, a gap exists between the stopper member 10 and the base plate 50 or the ground, and the gap can accommodate gravel, thereby avoiding jamming.

[0056] In the embodiment of the present application, the connecting arm 303 is rotatably connected to the connecting shaft 140, and the connecting shaft 140 is fixedly connected to the stopper 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 stopper member 10.

[0057] 6, 22 and 25, in an embodiment of the present application, the parking space lock further includes a reinforcing member 150, and the reinforcing member 150 includes a first support 1501, a second support 1502 and a third support 1503 which are integrally connected, the first support 1501 abuts against a side surface of the stopper member 10, the first support 1501 is provided with a third connecting hole 1504, the connecting shaft 140 is inserted into the upper part of the stopper member 10 through the third connecting hole 1504, the second support 1502 is inserted into the lower part of the stopper member 10, and the third support 1503 is engaged with the rear surface of the stopper member 10.

[0058] Based on the above structure, the present application utilizes reinforcing member 150 to reinforce the strength of connecting shaft 140 and stopper member 10, thereby mitigating deformation and cracking of connecting shaft 140 and stopper member 10, and at the same time, reinforcing member 150 reinforces the strength of connecting shaft 140 and stopper member 10, and at the same time, connection between reinforcing member 150 and connecting shaft 140 and stopper member 10 is realized.

[0059] Specifically, in order to improve the stability of the connection between the reinforcing member 150 and the stopper member 10, the connection portion between the stopper member 10 and the reinforcing member 150 has a solid structure, and the connection portion is provided with a corresponding mounting hole position for connecting to the connecting shaft 140 and a corresponding mounting hole position for connecting to the second support body 1502.

[0060] Specifically, the first support 1501 is arranged to extend along the thickness direction of the stopper member 10, and the second support 1502 and the third support 1503 are arranged to extend along the length direction of the stopper member 10, and in order to further reinforce the stability of the connection between the reinforcing member 150 and the stopper member 10, the connecting member is drilled through the second support 1502, the stopper member 10 and the third support 1503 along the thickness direction of the stopper member 10, thereby connecting the reinforcing member 150 and the stopper member 10 to each other, and the second support 1502, the stopper member 10 and the third support 1503 are provided with mounting hole positions for connecting to the connecting member.

[0061] It should be noted that the reinforcing member 150 supports the stopper member 10 in a manner that covers the side surface and the back surface of the stopper member 10, and supporting the stopper member 10 in this manner has a good reinforcing effect. Furthermore, according to this manner, the reinforcing member 150 can be inserted into the stopper member 10, and the outer surface of the reinforcing member 150 and the outer surface of the stopper member 10 are made flush with each other, which prevents the stopper member 10 from protruding from the outer surface of the stopper member 10, thereby protecting the reinforcing member 150.

[0062] 18 to 22, in an embodiment of the present application, the parking space lock further includes a second elastic member 160, and the connecting seat 120 is provided with a first mounting hole 170 and a second mounting hole 180, the installation direction of the first mounting hole 170 is perpendicular to the installation direction of the second mounting hole 180, the main shaft 130 is provided in the first mounting hole 170, the inner diameter of the first mounting hole 170 is larger than the outer diameter of the main shaft 130, the second elastic member 160 is provided 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 ground, so that the radial direction of the main shaft 130 abuts against the connecting seat 120.

[0063] Specifically, the second elastic member 160 is a straight tube spring or rubber.

[0064] Based on the above structure, the present application provides a second elastic member 160, which is advantageous for the return of the stopper member 10, and the inner diameter of the first mounting hole 170 is larger than the outer diameter of the main shaft 130. When a vehicle passes through the stopper member 10 in a flat, closed state, the stopper member 10 drops and returns, and in conjunction with this action, the other detection unit 190 can trigger the operation of the drive unit 20. In this way, a function can be realized such that the drive unit 20 goes to sleep when no vehicle is passing, which prevents the drive unit 20 from being in an activated state for a long period of time and further saves power consumption of the drive unit 20.

[0065] Since the inner diameter of the first mounting hole 170 is larger than the outer diameter of the main shaft 130, a movable gap is provided between the main shaft 130 and the connecting seat 120. When the stopper member 10 is in a flat closed state, when a vehicle passes over the stopper member 10, the stopper member 10 can drop and return.

[0066] Specifically, the first mounting hole 170 may be an oval hole or an elliptical hole, and the gap between the main shaft 130 and the support seat 80 for vertical movement is very small, generally 0.5 cm to 1 cm, as long as it does not affect the transmission between the drive unit 20 and the stopper member 10.

[0067] In the present application, a second elastic member 160 is provided to elastically support the main shaft 130, and the second elastic member 160 is mounted inside the connecting seat 120. In addition, the second mounting hole 180 is used to restrain the second elastic member 160 in the circumferential direction, thereby making it possible to maintain the expansion and contraction of the second elastic member 160 in a fixed direction, and preventing the second elastic member 160 from becoming ineffective due to distortion in the circumferential direction after long-term use, thereby extending the service life of the second elastic member 160.

[0068] It should be noted that the connecting seat 120 has a rigid structure. Thus, the combined structure of the connecting seat 120 and the second elastic member 160 can provide rigid support for the main shaft 130, and at the same time, the combined structure of the connecting seat 120 and the second elastic member 160 can provide elastic support for the main shaft 130, which provides a certain cushioning for the stopper member 10, reduces the impact force caused by the vehicle, and extends the service life of the stopper member 10 to a certain extent.

[0069] Furthermore, the detection unit 190 may be an angle detection unit 190 or a distance sensor, and how to use the detection unit 190 to detect the movement of the stopper member 10 and trigger the driving unit 20 to be turned on or off is a conventional technique and will not be repeated here.

[0070] It should be noted that, because the transmission mechanism 30 is provided, the stopper member 10 can perform dropping and returning operations when in the flat-laid closed state, without affecting the transmission connection between the drive unit 20 and the transmission mechanism 30, and in the above process, the external impact force received by the stopper member 10 when in the flat-laid closed state is an external impact force in a third direction, which is a direction that compresses the second elastic member 160 vertically.

[0071] Furthermore, when the stopper member 10 falls, because the connecting arm 303 is a rod member, the end of the connecting arm 303 close to the stopper member 10 is capable of slight bending deformation, and when the stopper member 10 returns to its original position, the connecting arm 303 also returns to its original position.

[0072] The specific use process of the present application is as follows: In the initial state, the stopper member 10 is in a flat closed state, allowing the vehicle to pass through the parking space lock, and at this time, the vehicle can freely enter and exit the parking space.

[0073] The drive unit 20 operates in the forward direction, and the drive unit 20 drives the stopper member 10 via the transmission mechanism 30, the connecting arm 303, and the connecting shaft 140 to reverse it in the forward direction around the main shaft 130, and the stopper member 10 is reversed to the raised open state. The stopper member 10 blocks the wheels of the vehicle, thereby preventing the vehicle from freely entering or exiting the parking space.

[0074] The drive unit 20 operates in the reverse direction, and the drive unit 20 drives the stopper member 10 via the transmission mechanism 30, the connecting arm 303, and the connecting shaft 140 to reverse the stopper member 10 around the main shaft 130 in the reverse direction, and the stopper member 10 is reversed to the flat-laid closed state, allowing the vehicle to pass through the parking space lock, and at this time, the vehicle can freely enter and exit the parking space.

[0075] It should be explained that, when the stopper member 10 is in the raised open state, a vehicle may enter or exit a parking space by impacting the stopper member 10 from the front or back of the stopper member 10. When the vehicle impacts the stopper member 10 from the front, it is considered that the stopper member 10 receives an external impact force in a first direction, and the impact force is transmitted to the nut by the connecting arm 303, so that the nut receives an external impact force in the first direction. When the vehicle impacts the stopper member 10 from the back of the stopper member 10, it is considered that the stopper member 10 receives an external impact force in a second direction, and the impact force is transmitted to the nut by the connecting arm 303, so that the nut receives an external impact force in the second direction.

[0076] It should be explained that, when the drive unit 20 operates in the forward direction, it means that the drive unit 20 rotates clockwise, and when the drive unit 20 operates in the reverse direction, it means that the drive unit 20 rotates counterclockwise; alternatively, when the drive unit 20 operates in the forward direction, it means that the drive unit 20 rotates counterclockwise, and when the drive unit 20 operates in the reverse direction, it means that the drive unit 20 rotates clockwise, but this is determined according to the actual situation and is not limited thereto.
