Description

TECHNICAL FIELD

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

[0003] Chinese patent CN112796253B discloses a new type of flat parking lock, which adopts a technical scheme that 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 flipped around the main shaft. The technical scheme has the following technical problems: (1) the rocker arm mechanism and the nut block rotate and move relative to each other, 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 lock, especially when the baffle is impacted by the vehicle, the rocker arm mechanism is prone to deformation and fracture; (2) the coaxial arrangement of the rocker arm mechanism and the baffle leads to a large swing amplitude of the rocker arm mechanism during operation, and the motor needs to output a large torque to flip the baffle, which is not conducive to the miniaturization and flat design of the parking lock.

[0070] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application herein are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0071] Referring to Figures 1-25 The present application discloses a parking 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 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 at the same time drives the connecting arm 303 to slide along the linear rail 40 and rotate relative to the moving piece 302, so as to make the connecting arm 303 drive the blocking piece 10 to overturn; when the blocking piece 10 is in an open state and is subjected to an external impact force, 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 perpendicular to the sliding direction of the moving piece 302.

[0072] Based on the above structure, the application realizes power transmission by using the transmission mechanism 30, the transmission mechanism 30 comprises 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, the connecting arm 303 rotates relative to the moving member 302, the above components constitute a slider linkage mechanism, while realizing the movement of the connecting arm 303, the strength of the connecting arm 303 and the stability of the transmission are ensured; the linear track 40 can assist the linear movement of the moving member 302, and the linear track 40 can limit the vertical displacement of the blocking piece 10 when the blocking piece 10 is in the open state and is impacted by external 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.

[0073] Specifically, the blocking piece 10 is plate-shaped, sheet-shaped or frame-shaped, and can block the wheels of the vehicle according to the actual application scene, and is not limited to a specific shape.

[0074] Specifically, the blocking piece 10 can be directly installed on the ground, or the blocking piece 10 is installed on the ground through the 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 used, each component can be integrated on the base plate 50, thereby facilitating the user to install the parking lock.

[0075] In the embodiment of the application, the linear track 40 is arranged 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.

[0076] Specifically, the transmission member 301 always abuts against the linear track 40 during movement, and the linear track 40 is used to limit the rotation of the moving member 302, so that the moving member 302 can only slide along the linear track 40.

[0077] Preferably, referring to Figure 4 and Figure 7 , the linear track 40 is arranged on both sides of the transmission member 301, and the two linear tracks 40 simultaneously limit the opposite sides of the moving member 302.

[0078] Referring to Figure 10 and Figure 14 , in the embodiment of the 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 impacted by external force, the first guide 60 limits the displacement of the second guide 304 in the direction perpendicular to the sliding direction.

[0079] In the embodiment of the 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.

[0080] Preferably, the first guide 60 is a sliding groove, and the second guide 304 is a sliding block.

[0081] Preferably, the linear track 40 is plate-shaped or block-shaped, and a sliding groove is formed in the middle of the linear track 40, which can be a groove or a slot, or a notch is formed in the bottom of the linear track 40.

[0082] More preferably, the linear track 40 is plate-shaped, and 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 the letter “L”.

[0083] During the movement of the transmission member 301, the sliding block always abuts against the sliding groove, so that when the blocking member 10 is in the open state and is subjected to an 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, and 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.

[0084] Taking the second guide 304 as a sliding block and the bottom of the linear track 40 as a notch for example, when the blocking member 10 is in the open state and is subjected to an impact force that is inclined downward, the impact force received by the blocking member 10 is transmitted to the sliding block, and according to the decomposition of force, the impact force received by the blocking member 10 is decomposed into a horizontal decomposed force and a vertical downward decomposed force, and 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 being damaged by the impact force. When the impact force on the blocking member 10 is inclined upward, the vertical upward decomposed force is transmitted to the top of the notch, which will not be described here again.

[0085] In addition, if the transmission member 301 is provided with linear tracks 40 on both sides, and 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 member 10 is subjected to an external impact force, the sliding block on one side transmits the vertical force to the top of the notch, and according to the balance of force, the sliding block on the other side transmits the vertical force to the base plate 50 or the ground, thereby protecting the transmission member 301 and the moving member 302 from being damaged by the impact force.

[0086] Referring to Figure 16 In the embodiment of the present application, the part of the second guide 304 close to the moving member 302 is rotationally connected with the connecting arm 303, and the part of the second guide 304 away from the moving member 302 is slidingly matched with the first guide 60.

[0087] 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.

[0088] Based on the above structure, the application realizes the sliding connection between the linear track 40 and the moving piece 302 by the first guide 60 and the second guide 304, and the relative positions of the linear track 40, the connecting arm 303 and the moving piece 302 are reasonably arranged, and each component is arranged compactly.

[0089] In the embodiment of the application, the driving unit 20 is a motor, the transmission member 301 is a screw rod, and the moving piece 302 is a nut, and the transmission member 301 is threadedly connected with the moving piece 302.

[0090] Referring to Figures 11-12 In the embodiment of the application, the parking stall lock further comprises a rotating piece 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 piece 70 through the second connecting hole 306; the support seat 80 is sleeved outside the connecting position of the screw rod and the rotating piece 70, the support seat 80 has a buffer gap in the axial direction with the screw rod, and the fixing seat 90 is sleeved outside the connecting position of the screw rod and the motor; when the blocking piece 10 is in the open state and 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 piece 70 along the linear track 40 in the buffer gap.

[0091] 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 is in the open state and 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 piece 70 along the linear track 40 in the buffer gap, and the blocking piece 10, the connecting arm 303, the nut, the screw rod and the motor are protected by the buffer gap, so that the deformation and damage thereof when subjected to the external impact force are reduced.

[0092] Continuing to refer to Figures 11-12 In the embodiment of the application, the parking stall 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 piece 70.

[0093] Specifically, the first elastic member 100 is a straight tube spring or rubber.

[0094] Based on the above structure, the first elastic member 100 is arranged in the second connecting hole 306, so that the first elastic member 100 does not occupy the external space of the screw rod, the effective length of the screw rod is ensured, and the miniaturization design of the parking stall lock is facilitated.

[0095] In the embodiment of the present 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 into the first connecting hole 305 is a polygonal shaft, and the part of the rotating member 70 inserted into the second connecting hole 306 is a polygonal shaft.

[0096] That is, the radial section of the part of the output end of the motor inserted into the first connecting hole 305 is polygonal, and the radial section of the part of the rotating member 70 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 rod to rotate, and the screw rod can also move axially relative to the output end of the motor, the rotating member 70 can rotate with the screw rod, and the screw rod can also drive the rotating member 70 to rotate, and the rotating member 70 can also move axially relative to the screw rod.

[0097] Taking the case of only providing the first elastic member 100 as an example, the specific movement process of the blocking piece 10 when subjected to external impact force is as follows:

[0098] When the blocking piece 10 is in the open state and is not subjected to external impact force, the screw rod abuts against the fixed seat 90 under the action of the first elastic member 100, and the buffer gap between the screw rod and the support seat 80 is the maximum value.

[0099] 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 driving the blocking piece 10 to move in the closing direction, referring to Figures 11-12 That is, the direction driving the nut to move along the screw rod in the left 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 rod to move along the linear track 40 in the direction close to the rotating member 70, and the first elastic member 100 is compressed, in 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, until the screw rod impacts the support seat 80, at this time, the buffer gap between the screw rod and the support seat 80 is 0, and the buffer gap between the screw rod and the fixed seat 90 is the maximum value.

[0100] 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 rod to move along the linear track 40 in the direction close to the output end of the motor, in this process, the buffer gap between the screw rod and the support seat 80 increases, and the buffer gap between the screw rod and the fixed seat 90 decreases, until the screw rod impacts the fixed seat 90, at this time, the buffer gap between the screw rod and the support seat 80 is the maximum value, and the buffer gap between the screw rod and the fixed seat 90 is 0.

[0101] It should be noted that the avoiding groove 110 can be arranged on the rotating part 70 and the output end of the motor, so as to avoid that the blocking piece 10 is impacted by the screw rod on the rotating part 70 and the output end of the motor when the blocking piece 10 is impacted by the external impact force; of course, the first elastic member 100 can also be arranged in the first connecting hole 305, so that when the blocking piece 10 is impacted by the external impact force in the second direction, the buffering can also be realized, and the second direction refers to the direction opposite to the first direction.

[0102] Referring to Figures 18-24 In the embodiment 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, 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 part 301 to move, the transmission part 301 drives the moving part 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 part 302, and the connecting arm 303 rotates relative to the moving part 302, and 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.

[0103] 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 part 301 to move, the transmission part 301 drives the moving part 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 part 302, and the connecting arm 303 rotates relative to the moving part 302, and 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, so that the driving unit 20 outputs a smaller torque to drive the blocking piece 10 to overturn; referring to Figure 5 and Figure 8 It can be known that 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 the transmission process, which is beneficial to realize the miniaturization design of the parking space lock.

[0104] 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 easily drive the blocking piece 10 to overturn.

[0106] 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 lock is installed; in the embodiment without the base plate 50, the connecting seat 120 can be directly fixed on the ground through concrete or screws, so that the parking lock is installed; due to the arrangement of the connecting seat 120, 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 jamming.

[0108] Referring to Figure 6 , Figure 22 and Figure 25 , in the embodiment of the application, the parking lock further comprises a reinforcing piece 150, the reinforcing piece 150 comprising a first support body 1501, a second support body 1502 and a third support body 1503 which are integrally connected; 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 into the upper part of the blocking piece 10 through the third connecting hole 1504, 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.

[0109] Based on the above structure, the application utilizes 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 while realizing the connection of the reinforcing piece 150 with the connecting shaft 140 and the blocking piece 10.

[0110] Specifically, in order to improve the connection stability of the reinforcing piece 150 and the blocking piece 10, the part where the blocking piece 10 is 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 at the part.

[0111] Specifically, the first support body 1501 is arranged in the thickness direction of the blocking piece 10, and the second support body 1502 and the third support body 1503 are arranged in 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 reinforcing piece 150 and the blocking piece 10 are connected together through a connecting piece penetrating the second support body 1502, the blocking piece 10 and the third support body 1503 in the thickness direction of the blocking piece 10, and 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.

[0112] It should be noted that the reinforcing member 150 cladding supports the side surface of the stop piece 10 and the back surface of the stop piece 10, which is better for supporting and strengthening the stop piece 10, and the reinforcing member 150 can be embedded into the stop piece 10, so that the outer surface of the reinforcing member 150 is flush with the outer surface of the stop piece 10, avoiding the stop piece 10 protruding from the outer surface of the stop piece 10, thereby protecting the reinforcing member 150.

[0113] Referring to Figures 18-22 In the embodiment of the application, the parking 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 is radially abutted against the connecting seat 120.

[0114] Specifically, the second elastic member 160 is a straight tube spring or rubber.

[0115] Based on the above structure, the second elastic member 160 is arranged to facilitate the reset of the stop 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 stop piece 10 in the flat closed state, the stop piece 10 generates a falling and resetting action, which cooperates with other detection units 190 to trigger the driving unit 20 to work, so that the driving unit 20 can be in sleep function when no vehicle passes through, avoiding the driving unit 20 being in a long-term working state, and further saving the power consumption of the driving unit 20.

[0116] 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 stop piece 10 is in the flat closed state, the vehicle passes through the stop piece 10, and the stop piece 10 can generate a falling and resetting action.

[0117] Specifically, the first mounting hole 170 can be an oblong hole or an elliptical hole, and the gap between the main shaft 130 and the support seat 80 is a small gap, generally 0.5-1cm, which does not affect the transmission between the driving unit 20 and the stop piece 10.

[0118] The second elastic piece 160 is installed in the interior of the connecting seat 120, and the circumferential direction of the second elastic piece 160 is constrained by the second mounting hole 180, so that the second elastic piece 160 can keep directional expansion and contraction, avoiding the second elastic piece 160 from being skewed in the circumferential direction and failing after long-term use, and prolonging the service life of the second elastic piece 160.

[0119] 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 piece 160 can provide rigid support for the main shaft 130, and the combined structure of the connecting seat 120 and the second elastic piece 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.

[0120] 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 which will not be repeated here.

[0121] It should be noted that the transmission mechanism 30 is provided, so that the blocking piece 10 can produce falling and resetting action in the flat closed state, and the transmission connection between the driving unit 20 and the transmission mechanism 30 is not affected. The external impact force received by the blocking piece 10 in the above process in the flat closed state is the external impact force in the third direction, and the third direction is the direction for driving the second elastic piece 160 to be vertically compressed.

[0122] 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.

[0127] It should be noted that when the blocking piece 10 is in the upright open state, the vehicle impacts the blocking piece 10 from the front or from the back of the blocking piece 10 in some cases, so as to realize entering and exiting 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 the external impact force in the first direction, the connecting arm 303 transmits 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 blocking piece 10 from the back of the blocking piece 10, it can be considered that the blocking piece 10 is subjected to the external impact force in the second direction, the connecting arm 303 transmits the impact force to the nut, so that the nut is subjected to the external impact force in the second direction.
