Description

A parking space lock TECHNICAL FIELD

[0001] The present application relates to the field of parking space locks, in particular to a parking space lock. BACKGROUND

[0002] The parking space lock is a mechanical device installed on the ground, which is used to prevent others from occupying the parking space or to limit the vehicle from leaving the parking space.

[0003] The new flat parking space lock in the related art adopts a technical scheme in which a motor drives a baffle to flip through a lead screw, a nut block, and a rocker arm mechanism. In order to realize the linear sliding of the nut block along the lead screw, a linear sliding groove is directly made on the rocker arm mechanism, and the rocker arm mechanism is used to avoid the rotation of the nut block. The rocker arm mechanism and the baffle are coaxially arranged, and the rocker arm mechanism and the baffle are both flipped around the main shaft. The technical scheme has the following technical problems: (1) The rocker arm mechanism and the nut block relatively rotate and move at the same time. The linear sliding groove not only reduces the overall strength of the rocker arm mechanism, but also increases the assembly difficulty and transmission complexity between the rocker arm mechanism and the nut block. In the process of long-term use of the parking space lock, especially when the baffle is impacted by a vehicle, the rocker arm mechanism is prone to deformation and fracture; (2) The coaxial arrangement of the rocker arm mechanism and the baffle causes a large swing amplitude of the rocker arm mechanism during operation. 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 space lock.

[0004] SUMMARY

The parking space lock of the present application 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 strength of the connecting arm and the stability of the transmission are ensured while the movement of the connecting arm is realized. The linear track can assist the linear movement of the moving member. When the blocking piece is in the open state and is impacted by external force, the linear track can limit the vertical displacement, that is, the linear track can offset the external impact force to protect the moving member and avoid deformation and damage of the moving member.

[0069] Referring to FIGS. 1-25, the application discloses a parking space lock, comprising: a blocking piece 10; a driving unit 20; a transmission mechanism 30, the transmission mechanism 30 comprising a transmission piece 301, a moving piece 302 and a connecting arm 303, the transmission piece 301, the moving piece 302 and the connecting arm 303 being connected in sequence, the driving unit 20 being in transmission connection with the transmission piece 301, and the connecting arm 303 being in rotational connection with the blocking piece 10; a linear rail 40, the linear rail 40 being in sliding connection with the moving piece 302 and limiting the displacement of the moving piece 302 in the linear rail in a direction perpendicular to the sliding direction of the moving piece 302; when the driving unit 20 drives the transmission piece 301 to move, the transmission piece 301 drives the moving piece 302 to slide along the linear rail 40, and drives the connecting arm 303 to slide along the linear rail 40 and rotate relative to the moving piece 302, so that the connecting arm 303 drives the blocking piece 10 to overturn; when the blocking piece 10 is impacted by external force in the open state, the blocking piece 10 drives the connecting arm 303 to move, the connecting arm 303 drives the moving piece 302 to slide relative to the linear rail 40, and the linear rail 40 limits the displacement of the moving piece 302 in the direction perpendicular to the sliding direction of the moving piece 302.

[0070] Based on the above structure, the application utilizes the transmission mechanism 30 to realize power transmission, the transmission mechanism 30 comprising the transmission piece 301, the moving piece 302 and the connecting arm 303, the linear rail 40 and the connecting arm 303 being independently arranged, the moving piece 302 moving relative to the linear rail 40, and the connecting arm 303 rotating relative to the moving piece 302, the above components constituting a slider-crank mechanism, which ensures the strength of the connecting arm 303 and the stability of transmission while realizing the movement of the connecting arm 303; the linear rail 40 can not only assist the linear movement of the moving piece 302, but also limit the displacement of the blocking piece 10 in the vertical direction when the blocking piece 10 is impacted by external force in the open state, that is, the linear rail 40 can offset the external impact force, thereby protecting the moving piece 302 and avoiding deformation and damage of the moving piece 302.

[0071] Specifically, the blocking piece 10 is plate-shaped, sheet-shaped or frame-shaped, which is determined according to the actual application scene and can block the wheels of the vehicle, and is not limited to a specific shape.

[0072] Specifically, the blocking piece 10 can be directly installed on the ground, or the blocking piece 10 is installed on the ground through a base plate 50, and the specific installation mode of the blocking piece 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 on the base plate 50, thereby facilitating the user to install the parking space lock.

[0073] In the embodiment of the application, the transmission piece 301 is provided with the linear rail 40 on one side or both sides, and the transmission piece 301 and the linear rail 40 are parallel to each other.

[0074] Specifically, the transmission member 301 always abuts against the linear track 40 during movement, and the linear track 40 limits the rotation of the moving member 302, so that the moving member 302 can only slide along the linear track 40.

[0075] Preferably, referring to FIG. 4 and FIG. 7, the two sides of the transmission member 301 are provided with linear tracks 40, and the two linear tracks 40 simultaneously limit the opposite sides of the moving member 302.

[0076] Referring to FIG. 10 and FIG. 14, in the embodiment of the present application, the linear track 40 is provided with a first guide 60, and the moving member 302 is provided with a second guide 304 which is in sliding cooperation with the first guide 60, when the moving member 302 is subjected to external impact force, the first guide 60 limits the displacement of the second guide 304 in the direction perpendicular to the sliding direction.

[0077] In the embodiment of the present application, the first guide 60 is a sliding groove or a sliding block, and the second guide 304 is a sliding block or a sliding groove.

[0078] Preferably, the first guide 60 is a sliding groove, and the second guide 304 is a sliding block.

[0079] Preferably, the linear track 40 is plate-shaped or block-shaped, a sliding groove is formed in the middle of the linear track 40, the sliding groove can be a groove or a slot, or a notch is formed in the bottom of the linear track 40.

[0080] More preferably, the linear track 40 is plate-shaped, a notch is formed in the bottom of the linear track 40, and the transverse cross section of the linear track 40 is in the shape of "L".

[0081] During the movement of the transmission member 301, the sliding block always abuts against the sliding groove, so when the blocking member 10 is in the open state and subjected to external impact force, the impact force received by the blocking member 10 is transmitted to the connecting arm 303 and at the same time to the second guide 304 of the moving member 302, since the linear track 40 is arranged on the ground or the base plate 50, the external impact force can be transmitted to the linear track 40 and the ground, or to the linear track 40, the base plate 50 and the ground.

[0082] The second guide 304 is a sliding block, and the bottom of the linear track 40 is provided with a notch. When the blocking piece 10 is in the open state and is subjected to an impact force inclined downward, the impact force received by the blocking piece 10 is transmitted to the sliding block. According to force decomposition, the impact force received by the blocking piece 10 is decomposed into a horizontal decomposed force and a vertical downward decomposed force. The sliding block is subjected to the horizontal decomposed force and the vertical downward decomposed force, respectively. The horizontal decomposed force makes the sliding block move linearly in the notch, and the vertical downward decomposed force is transmitted to the base plate 50 or the ground, thereby protecting the transmission member 301 and the moving member 302 from damage caused by the impact force. When the blocking piece 10 is subjected to an impact force inclined upward, the vertical upward decomposed force is transmitted to the top of the notch, and details are not described herein.

[0083] In addition, if the transmission member 301 is provided with the linear track 40 on both sides, the sliding blocks on both sides of the moving member 302 abut against the notches of the linear tracks 40 on both sides. When the blocking piece 10 is subjected to an external impact force, one sliding block transmits the vertical force to the top of the notch, and the other sliding block transmits the vertical force to the base plate 50 or the ground according to force balance, thereby protecting the transmission member 301 and the moving member 302 from damage caused by the impact force.

[0084] Referring to FIG. 16, in the embodiment of the present application, the second guide 304 is rotationally connected to the connecting arm 303 near the moving member 302, and the second guide 304 is slidably connected to the first guide 60 away from the moving member 302.

[0085] Specifically, the second guide 304 is a rod-shaped protrusion, and the specific shape of the second guide 304 is determined according to the specific shape of the first guide 60 and the specific shape of the connecting arm 303.

[0086] Based on the above structure, the first guide 60 and the second guide 304 are used to achieve 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 components are arranged compactly.

[0087] In the embodiment of the present application, the driving unit 20 is a motor, the transmission member 301 is a screw rod, and the moving member 302 is a nut. The transmission member 301 is threadedly connected to the moving member 302.

[0088] Referring to FIGS. 11-12, in the embodiment of the application, the parking lock further comprises a rotating member 70, a support seat 80, and a fixing seat 90; the axial two ends of the screw rod are respectively provided with a first connecting hole 305 and a second connecting hole 306, the axial one end of the screw rod is inserted with the output end of the motor through the first connecting hole 305, and the axial other end of the screw rod is inserted with the rotating member 70 through the second connecting hole 306; the support seat 80 is sleeved outside the connecting position of the screw rod and the rotating member 70, the support seat 80 and the screw rod have a buffer gap in the axial direction, and the fixing seat 90 is sleeved outside the connecting position of the screw rod and the motor; when the blocking piece 10 in the open state is subjected to an external impact force, the nut and the screw rod are driven by the connecting arm 303 to move together relative to the support seat 80 and the rotating member 70 in the buffer gap along the linear track 40.

[0089] Based on the above structure, the support seat 80 and the screw rod have a buffer gap in the axial direction, when the blocking piece 10 in the open state is subjected to an external impact force, the nut and the screw rod are driven by the connecting arm 303 to move together relative to the support seat 80 and the rotating member 70 in the buffer gap along the linear track 40, and the blocking piece 10, the connecting arm 303, the nut, the screw rod, and the motor are buffered and protected by the buffer gap, reducing the deformation and damage thereof when subjected to an external impact force.

[0090] Continuing to refer to FIGS. 11-12, in the embodiment of the application, the parking lock further comprises a first elastic member 100, the first elastic member 100 is arranged in the second connecting hole 306, and the axial one end of the first elastic member 100 abuts against the screw rod, and the axial other end of the first elastic member 100 abuts against the rotating member 70.

[0091] Specifically, the first elastic member 100 is a straight tube spring or rubber.

[0092] Based on the above structure, the first elastic member 100 is arranged in the second connecting hole 306, avoiding the first elastic member 100 from occupying the external space of the screw rod, ensuring the effective length of the screw rod, and facilitating the miniaturization design of the parking lock.

[0093] In the embodiment of the application, the first connecting hole 305 and the second connecting hole 306 are both polygonal holes, the part of the output end of the motor inserted with the first connecting hole 305 is a polygonal shaft, and the part of the rotating member 70 inserted with the second connecting hole 306 is a polygonal shaft.

[0094] That is, the radial section of the part where the output end of the motor is inserted into the first connecting hole 305 is polygonal, and the radial section of the part where the rotating member 70 is inserted into the second connecting hole 306 is polygonal; 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, and the rotating member 70 can also drive the screw to rotate, and the screw can also move axially relative to the rotating member 70.

[0095] Taking the case where only the first elastic member 100 is provided as an example, the specific movement process of the blocking piece 10 when subjected to external impact force is as follows:

[0096] When the blocking piece 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 abuts against the fixed seat 90, and the buffer gap between the screw and the support seat 80 is the maximum value.

[0097] When the blocking piece 10 is in the open state and is subjected to external impact force, for example, when the blocking piece 10 is subjected to external impact force that drives the blocking piece 10 to move in the closing direction, referring to FIGS. 11-12, that is, the direction in which the nut is driven to move along the screw in the left direction, this direction is defined as the first direction; when the blocking piece 10 is subjected to external impact force in the first direction, the external impact force in the first direction is transmitted to the nut through the blocking piece 10 and the connecting arm 303, the nut drives the screw to move together along the linear track 40 in the direction of approaching the rotating member 70, and the first elastic member 100 is compressed, in 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.

[0098] When the external impact force in the first direction on the blocking piece 10 disappears, the first elastic member 100 resets, under the action of the first elastic member 100, the nut drives the screw to move along the linear track 40 in the direction of approaching the output end of the motor, in 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.

[0099] It should be noted that the rotating member 70 and the output end of the motor can be provided with a relief groove 110 to avoid the screw from impacting the rotating member 70 and the output end of the motor when the blocking piece 10 is subjected to external impact force; of course, the first elastic member 100 can also be provided in the first connecting hole 305, so that when the blocking piece 10 is subjected to external impact force in the second direction, which is opposite to the first direction, the buffer can also be achieved.

[0100] Referring to FIGS. 18-24, in the embodiments of the present application, the parking space lock further comprises a connecting seat 120, the blocking piece 10 is rotationally connected with the connecting seat 120 through a main shaft 130, the connecting arm 303 is rotationally connected with the blocking piece 10 through a connecting shaft 140, 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 piece 302 to slide along the linear track 40, at the same time, the connecting arm 303 slides along the linear track 40 following the moving piece 302, and the connecting arm 303 rotates relative to the moving piece 302, the connecting arm 303 drives the blocking piece 10 to overturn around the main shaft 130, so as to open or close the blocking piece 10.

[0101] Based on the above structure, 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 piece 302 to slide along the linear track 40, at the same time, the connecting arm 303 slides along the linear track 40 following the moving piece 302, and the connecting arm 303 rotates relative to the moving piece 302, the connecting arm 303 drives the blocking piece 10 to overturn around the main shaft 130, so as to open or close the blocking piece 10, thereby the driving unit 20 outputs a smaller torque to drive the blocking piece 10 to overturn; referring to FIGS. 5 and 8, 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 amplitude of the connecting arm 303 is small during transmission, which is beneficial to realize the miniaturization design of the parking space lock.

[0102] Specifically, the offset value of the central axis of the main shaft 130 and the central axis of the connecting shaft 140 is determined according to the actual application scene, so as to facilitate the driving unit 20 to drive the blocking piece 10 to overturn.

[0103] Specifically, the connecting seat 120 is arranged on the rotation side of the blocking piece 10, the connecting seat 120 supports the blocking piece 10, and the main shaft 130 and the support seat 80 form a hinge structure; in this way, the number and installation interval of the connecting seats 120 can be controlled to form multi-point support or line support on the rotation side of the blocking piece 10, which not only increases the strength of the blocking piece 10, but also assists the blocking piece 10 to overturn, and at the same time, it can avoid adding components at the end of the blocking piece 10 away from the driving unit 20, so as to ensure the installation space of the parking space lock in the axial direction of the blocking piece 10.

[0104] Specifically, the connecting seat 120 is fixed on the base plate 50 or directly fixed on the ground; the base plate 50 is fixed on the ground through concrete or screws, so that the parking space lock is installed; in the embodiments without using the base plate 50, the connecting seat 120 can be directly fixed on the ground through concrete or screws, so that the parking space lock is installed; since the connecting seat 120 is arranged, there is a gap between the blocking piece 10 and the base plate 50 or the ground, which can accommodate sand and gravel to avoid being stuck.

[0105] In the embodiment of the present application, the connecting arm 303 is rotationally connected with the connecting shaft 140, and the connecting shaft 140 is fixedly connected with the blocking piece 10; or, the connecting arm 303 is fixedly connected with the connecting shaft 140, and the connecting shaft 140 is rotationally connected with the blocking piece 10.

[0106] Referring to FIGS. 6, 22 and 25, in the embodiment of the present application, the parking spot lock further comprises a reinforcing piece 150, which comprises a first support body 1501, a second support body 1502 and a third support body 1503 connected integrally; the first support body 1501 abuts against the side surface of the blocking piece 10, the first support body 1501 is provided with a third connecting hole 1504, the connecting shaft 140 is inserted through the third connecting hole 1504 and connected with the upper part of the blocking piece 10, the second support body 1502 is inserted into the lower part of the blocking piece 10, and the third support body 1503 is buckled on the back surface of the blocking piece 10.

[0107] Based on the above structure, the present application uses the reinforcing piece 150 to strengthen the strength of the connecting shaft 140 and the blocking piece 10, and slow down the deformation and cracking of the connecting shaft 140 and the blocking piece 10. The reinforcing piece 150 strengthens the strength of the connecting shaft 140 and the blocking piece 10, and realizes the connection of the reinforcing piece 150 with the connecting shaft 140 and the blocking piece 10.

[0108] Specifically, in order to improve the connection stability of the reinforcing piece 150 and the blocking piece 10, the part of the blocking piece 10 connected with the reinforcing piece 150 is of a solid structure, and assembly hole positions for connecting with the connecting shaft 140 and the second support body 1502 are made in this part.

[0109] Specifically, the first support body 1501 is arranged to extend along the thickness direction of the blocking piece 10, and the second support body 1502 and the third support body 1503 are arranged to extend along the length direction of the blocking piece 10. In order to further improve the connection stability of the reinforcing piece 150 and the blocking piece 10, the second support body 1502, the blocking piece 10 and the third support body 1503 are penetrated by a connecting piece along the thickness direction of the blocking piece 10, so as to connect the reinforcing piece 150 and the blocking piece 10 together. The second support body 1502, the blocking piece 10 and the third support body 1503 are provided with assembly hole positions for connecting with the connecting piece.

[0110] It should be noted that the reinforcing piece 150 supports and covers the side surface of the blocking piece 10 and the back surface of the blocking piece 10, which has good supporting and strengthening effect on the blocking piece 10. In addition, the reinforcing piece 150 can be embedded into the blocking piece 10, so that the outer surface of the reinforcing piece 150 is flush with the outer surface of the blocking piece 10, avoiding the blocking piece 10 protruding from the outer surface of the blocking piece 10, thereby protecting the reinforcing piece 150.

[0111] Referring to FIGS. 18-22, in the embodiment of the present application, the parking spot lock further comprises a second elastic member 160, the connecting seat 120 is provided with a first mounting hole 170 and a second mounting hole 180, 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, 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, the other end of the second elastic member 160 abuts against the connecting seat 120 or the ground, so that the main shaft 130 radially abuts against the connecting seat 120.

[0112] Specifically, the second elastic member 160 is a straight tube spring or rubber.

[0113] Based on the above structure, the present application sets the second elastic member 160 to facilitate the resetting of the blocking piece 10, and the inner diameter of the first mounting hole 170 is greater than the outer diameter of the main shaft 130, when a vehicle passes through the blocking piece 10 in the flat closed state, the blocking piece 10 generates a falling and resetting action, which can trigger the driving unit 20 to work in cooperation with other detection units 190, so that the driving unit 20 can be in sleep mode when there is no vehicle passing through, avoiding the driving unit 20 being in the on state for a long time, and further saving the power consumption of the driving unit 20.

[0114] Since the inner diameter of the first mounting hole 170 is greater than the outer diameter of the main shaft 130, there is a clearance between the main shaft 130 and the connecting seat 120, when the blocking piece 10 is in the flat closed state, the vehicle passes through the blocking piece 10, and the blocking piece 10 can generate a falling and resetting action.

[0115] Specifically, the first mounting hole 170 can be an oblong hole or an elliptical hole, the clearance between the main shaft 130 and the support seat 80 is a small clearance, generally 0.5-1 cm, which does not affect the transmission between the driving unit 20 and the blocking piece 10.

[0116] The present application elastically supports the main shaft 130 by setting the second elastic member 160, installs the second elastic member 160 in the interior of the connecting seat 120, and uses the second mounting hole 180 to constrain the circumferential direction of the second elastic member 160, so that the second elastic member 160 can keep directional stretching and contraction, avoiding the second elastic member 160 being skewed in the circumferential direction and failing after long-term use, prolonging the service life of the second elastic member 160.

[0117] 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, and the combined structure of the connecting seat 120 and the second elastic member 160 provides elastic support for the main shaft 130, provides a certain buffer for the blocking piece 10, reduces the impact force of the vehicle, and prolongs the service life of the blocking piece 10 to a certain extent.

[0118] Further, the detection unit 190 can be an angle detection unit 190 or a distance sensor. How to use the detection unit 190 to detect the action of the blocking piece 10 and trigger the start and stop of the driving unit 20 is a prior art and will not be repeated here.

[0119] It should be noted that due to the transmission mechanism 30, the blocking piece 10 can fall and reset when it is in a flat closed state, and will not affect the transmission connection between the driving unit 20 and the transmission mechanism 30. The external impact force on the blocking piece 10 in the above process is a third direction external impact force, and the third direction is a direction for vertically compressing the second elastic member 160.

[0120] Further, when the blocking piece 10 falls, the end of the connecting arm 303 close to the blocking piece 10 can be slightly bent and deformed, and when the blocking piece 10 resets, the connecting arm 303 also resets.

[0121] The specific use process of the present application is as follows:

[0122] In the initial state, the blocking piece 10 is in a flat closed state, and the vehicle can pass through the parking space lock. At this time, the vehicle can freely enter and exit the parking space.

[0123] The driving unit 20 works in the forward direction, and the driving unit 20 drives the blocking piece 10 to rotate in the forward direction around the main shaft 130 through the transmission mechanism 30, the connecting arm 303, and the connecting shaft 140. The blocking piece 10 is turned to a standing open state, and the blocking piece 10 blocks the vehicle, thereby blocking the vehicle from freely entering and exiting the parking space.

[0124] The driving unit 20 works in the reverse direction, and the driving unit 20 drives the blocking piece 10 to rotate in the reverse direction around the main shaft 130 through the transmission mechanism 30, the connecting arm 303, and the connecting shaft 140. The blocking piece 10 is turned to a flat closed state, and the vehicle can pass through the parking space lock. At this time, the vehicle can freely enter and exit the parking space.

[0125] It should be noted that when the blocking piece 10 is in the erected open state, the vehicle impacts the blocking piece 10 from the front of the blocking piece 10 or from the back of the blocking piece 10 in some cases, thereby achieving access to the parking space; when the vehicle impacts the blocking piece 10 from the front of the blocking piece 10, it can be considered that the blocking piece 10 is subjected to an external impact force in the first direction, and the connecting arm 303 transmits the impact force to the nut, so that the nut is subjected to an external impact force in the first direction; when the vehicle impacts the blocking piece 10 from the back of the blocking piece 10, it can be considered that the blocking piece 10 is subjected to an external impact force in the second direction, and the connecting arm 303 transmits the impact force to the nut, so that the nut is subjected to an external impact force in the second direction.

[0126] It should be noted that the forward operation of the driving unit 20 is the clockwise rotation of the driving unit 20, and the reverse operation of the driving unit 20 is the counterclockwise rotation of the driving unit 20; or, the forward operation of the driving unit 20 is the counterclockwise rotation of the driving unit 20, and the reverse operation of the driving unit 20 is the clockwise rotation of the driving unit 20; it depends on the actual situation and is not limited thereto.
