Description

Technical Field

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

[0002] With the development of the country and the progress of society, cars are becoming more and more common as a means of transportation. With the increase in the number of cars, parking space resources are tight and supply and demand are unbalanced. In order to strengthen management, some parking places, especially roadside parking spaces, usually install parking locks on the parking spaces. Common parking locks are unmanned and automatically controlled. When there is no car parked, the parking lock is closed and does not affect the normal passage of pedestrians. When a car enters the parking space, the parking lock automatically recognizes and locks to restrict the movement of the car. The owner needs to scan the code to pay, and the parking lock is closed before the car can leave.

[0003] At present, in order to ensure the rotation and lifting of the parking lock flap to achieve the lock lifting effect, a parking lock movement with a worm gear is often used to drive the rotation of the flap. However, the worm gear is large in size, which leads to a large chassis size, which affects the user's parking and causes scratches and foot blocking when opening the car door.

[0004] In order to solve the above problems, Chinese patent CN112796253B discloses a new type of flat parking lock, which uses a screw and a nut to cooperate. The nut drives the rocker arm to swing, and then the rocker arm drives the baffle to rotate, so as to replace the worm gear movement and reduce the volume of the parking lock movement. However, the shaft connecting the rocker arm and the baffle is on the same straight line as the axis of rotation of the baffle, so it is necessary to provide a larger force for the rocker arm to drive, and then a driver with a larger torque is required to drive the baffle to rotate, or a reducer with more stages is used to increase the final output torque, so a driver with stronger performance or a larger volume under the same conditions is required, or a reducer with more stages, that is, a larger volume is used, so that the movement used in the disclosed new type of flat parking lock still has the problem of large volume. Utility Model Content

[0005] In order to overcome at least one of the defects of the prior art described above, the purpose of the present invention is to provide a parking lock which can solve the problem that the size of the movement is still large due to the high power requirement for driving the flap.

[0006] The technical solution adopted by the utility model to solve the problem is:

[0007] A parking lock, comprising:

[0008] A driving assembly, the driving assembly comprising a driver and a driving block, the driver being drivingly connected to the driving block;

[0009] A flap, wherein the flap has a driving axis and a rotation axis which are parallel to each other, the length direction of the flap extends along the rotation axis, the width value of the flap is set to a, the distance between the driving axis and the rotation axis is not greater than a / 2, and the flap is provided with a hinge along the rotation axis so that the flap is hingedly mounted on an external mounting carrier;

[0010] A connecting arm, wherein the driver drives the flap to rotate through the driving block and the connecting arm in sequence, the connecting arm having an input end and an output end, the input end of the connecting arm being rotationally connected to the driving block, and the output end of the connecting arm being rotationally connected to the flap;

[0011] When the driver drives the driving block to move, the driving block drives the input end of the connecting arm to move, and at the same time the input end of the connecting arm rotates relative to the driving block, so that the output end of the connecting arm drives the flap to rotate around the rotation axis at the driving axis.

[0012] By adopting the above scheme, since the driving axis and the rotation axis of the flap are not on the same straight line, when the output end of the connecting arm drives the flap to rotate around the rotation axis at the driving axis, a force arm will be formed between the output end of the connecting arm and the rotation axis. Compared with the prior art in which the power input shaft of the flap is coaxially designed with the rotation axis and has no force arm, the output end of the connecting arm of the present application needs to apply much less force when outputting the same torque, which allows the driver of the present application to use a small-power driver to output a relatively large torque. In addition, since the distance between the driving axis and the rotation axis is not greater than a / 2, and the distance that the output end of the connecting arm moves upward is the distance that the driving axis moves upward, the upward distance of the output end of the connecting arm will not exceed a / 2 of the flap, that is, the distance that the connecting arm moves upward is small, ensuring the small size of the transmission part of the parking lock.

[0013] The flap is provided with hinges along the rotation axis to facilitate the installation of the flap and the installation carrier.

[0014] The driver drives the input end of the connecting arm to move back and forth in a straight line through the driving block, so that the output end of the connecting arm pushes upward or pulls downward at an angle at the driving axis to rotate the flap around the rotation axis, ensuring that the motion trajectory of the input end of the connecting arm is fixed and the line is short, which can reduce the space occupied by the input end. The output end of the connecting arm is driven by the input end of the connecting arm to push upward or pull downward at an angle at the driving axis to rotate the flap around the rotation axis.

[0015] In addition, a driver is used in conjunction with a driving assembly of a driving block, and the driver drives the driving block to reciprocate, thereby driving the input end of the connecting arm to reciprocate.

[0016] Further, in the width direction of the flap, the rotation axis is located on one side of the flap, and the drive axis is located between the middle of the flap and the rotation axis.

[0017] By adopting the above solution, the output end of the connecting arm can use a smaller force and complete the flipping of the flap in a shorter movement distance.

[0018] Furthermore, the connecting arm is arranged obliquely, and the output end of the connecting arm is higher than the input end of the connecting arm.

[0019] By adopting the above solution, when the driving block drives the connecting arm to move, a certain guiding effect is provided on the movement trajectory of the connecting arm, so that the movement of the connecting arm is smoother and more powerful.

[0020] Furthermore, the height of the plane where the driving axis is located is higher than the height of the plane where the rotation axis is located.

[0021] By adopting the above solution, when the connecting arm pushes the flap to flip up, the power provided by the connecting arm is guided to a certain extent, thereby further reducing the power required by the connecting arm to push the flap.

[0022] Furthermore, the linear movement direction of the input end of the connecting arm is perpendicular to the length direction of the flap and parallel to the mounting carrier plane of the flap.

[0023] By adopting the above solution, the distance between the connecting arm and the flap is made smaller, and the structure between the connecting arm, the driving assembly and the flap of the parking lock is made more compact, thereby achieving the purpose of reducing the size of the parking lock.

[0024] Further, in the length direction of the flap, the connecting arm and the driving assembly are both located at the same end of the flap, and the connecting arm is located between the flap and the driving assembly.

[0025] By adopting the above solution, the drive assembly (ie, the driver and the drive block) and the connecting arm are arranged on the same side of the flap in the length direction, rather than being arranged inside the flap or at the bottom of the flap, thereby reducing the overall thickness of the parking lock.

[0026] Further, the driver is transmission-connected with a screw rod, the driving block is a nut, the driving block is threadedly connected to the screw rod, and the driver drives the screw rod to rotate to drive the driving block to reciprocate along the axial direction of the screw rod.

[0027] By adopting the above solution, a smaller screw rod and drive block are used to cooperate, thereby ensuring that the size of the drive component is reduced while providing stable power output.

[0028] Furthermore, it also includes a drive mounting bracket, the drive is transmission connected to a screw rod, the drive block is threadedly connected to the screw rod, the drive mounting bracket includes a first bracket plate and a second bracket plate, the rotating shaft of the drive passes through the first bracket plate, one end of the screw rod is transmission connected to the drive, passes through the rotating shaft of the first bracket plate, and the other end is assembled on the second bracket plate.

[0029] By adopting the above solution, the drive mounting bracket facilitates the installation of the driver and the drive block, and the driver and the second bracket plate support and limit the two ends of the screw rod, thereby improving the stability of the screw rod during transmission and the impact resistance.

[0030] Furthermore, the driver includes a motor and a reducer, the motor is transmission-connected to the screw rod through the reducer, and the motor, the reducer and the screw rod are coaxially arranged.

[0031] By adopting the above solution, the motor, reducer and screw are coaxially arranged, which facilitates the integration of the above three with other components.

[0032] Furthermore, the movement direction of the driving block is consistent with the width direction of the flap.

[0033] By adopting the above solution, the movement direction of the drive block is set perpendicular to the length direction of the flap, which is equivalent to the drive assembly and the connecting arm being located on the extension of the length direction of the flap, making the structure of the parking lock more compact and reducing the footprint of the parking lock.

[0034] Furthermore, the flap is provided with a first rotating connection member at one end of the driving axis toward the connecting arm, and the output end is provided with a second rotating connection member, and the first rotating connection member is rotatably connected with the second rotating connection member; one of the first rotating connection member and the second rotating connection member is an axial hole, and the other is a rotating shaft.

[0035] By adopting the above scheme, the first rotating connecting member can be one of the shaft hole and the rotating shaft, and the second rotating connecting member can be the other of the shaft hole or the rotating shaft. The rotating shaft can be inserted into the shaft hole to realize the rotating connection between the driving block and the input end, which is convenient for installation, simple in structure, and easy to produce, assemble and maintain.

[0036] Furthermore, the first rotating connection member is a rotating shaft fixedly mounted on the flap, and the second rotating connection member is an axial hole, and one end of the rotating shaft extending out of the flap is inserted into the axial hole and rotatably connected thereto.

[0037] Furthermore, the rotating shaft is provided with a limiting boss, and the shaft hole is provided with a limiting step, and when the rotating shaft is inserted into the shaft hole, the limiting boss cooperates with the limiting step.

[0038] By adopting the above solution, the limiting boss and the limiting step cooperate to prevent the first rotating connecting member and the second rotating connecting member from being disconnected.

[0039] Furthermore, the driving block is provided with a third rotating connection member, and the input end is provided with a fourth rotating connection member that is rotatably connected to the third rotating connection member.

[0040] Furthermore, one of the third rotating connection member and the fourth rotating connection member is an axial hole, and the other is a rotating shaft.

[0041] By adopting the above scheme, the third rotating connecting member can be one of the shaft hole and the rotating shaft, and the fourth rotating connecting member can be the other of the shaft hole or the rotating shaft. The rotating shaft can be inserted into the shaft hole to realize the rotational connection between the driving block and the input end, which is convenient for installation, simple in structure, and easy to produce, assemble and maintain.

[0042] Further, a length direction of the connecting arm extending from the input end to the output end is parallel to a movement direction of the driving block.

[0043] By adopting the above solution, the connecting arm is arranged parallel to the movement direction of the driving block, which can ensure that the structure of the driving block and the flap through the connecting arm transmission is more compact.

[0044] Furthermore, it also includes a guide component, the guide direction of the guide component is parallel to the moving direction of the driving block, and the driving block moves along the guide direction.

[0045] By adopting the above solution, the guide assembly limits the movement of the drive block, thereby preventing the drive block from deviating in the non-movement direction.

[0046] Furthermore, the guide assembly includes a first guide member and a second guide member that are slidably matched, the first guide member is arranged between the driving block and the flap, the second guide member is arranged on the side of the driving block facing the first guide member, and the second guide member arranged on the driving block slides along the first guide member.

[0047] By adopting the above solution, the first guide member cooperates with the second guide member to limit the moving direction of the driving block, thereby preventing the driving block from deviating in the non-moving direction.

[0048] Furthermore, the driving block is provided with a third rotating connecting member, and the third rotating connecting member is rotatably connected to the input end of the connecting arm; and the second guide member is provided on the third rotating connecting member.

[0049] By adopting the above solution, compared with the split design of the second guide member and the third rotating connection member, the second guide member is arranged on the third rotating connection member, which facilitates the production of the driving block and can also reduce the volume of the driving component.

[0050] Furthermore, the first guide member is provided with a first sliding groove, the second guide member is provided with a first sliding block, and the first sliding block is slidably arranged along the first sliding groove.

[0051] Further, the guide assembly includes a third guide member and a fourth guide member that are slidably matched, the fourth guide member is arranged on the side of the input end of the driving block facing away from the connecting arm, the driving block is located between the first guide member and the third guide member, and the driving block moves along the width direction of the flap along the third guide member.

[0052] By adopting the above solution, the third guide member and the fourth guide member are provided on the basis of the first guide member and the second guide member, so as to well limit the movement track of the driving block and prevent the driving block from deviating in the non-movement direction.

[0053] Furthermore, the third guide member is provided with a second sliding groove, the fourth guide member is provided with a second sliding block, and the second sliding block is slidably arranged along the second sliding groove.

[0054] Furthermore, the flap is provided with a reinforcement piece at the first rotating connection piece.

[0055] By adopting the above scheme, the reinforcement piece can strengthen the strength of the flap and the first rotating connection piece, prevent deformation or cracking of the flap at the first rotating connection piece, improve the strength of the connection between the flap and the first rotating connection piece, thereby improving the bearing capacity and stability of the flap.

[0056] Furthermore, the first rotating connecting member is a rotating shaft, the reinforcing member is provided with an avoidance hole for one end of the rotating shaft to pass through, and one end of the rotating shaft passes through the avoidance hole and is assembled on the flap; the second rotating connecting member is an axial hole, and the other end of the rotating shaft is rotatably connected to the axial hole.

[0057] By adopting the above solution, the rotating shaft passes through the avoidance hole of the reinforcement. After the rotating shaft is subjected to force, the force will mainly act on the reinforcement, and then be transmitted to the flap through the reinforcement, thereby improving the bearing capacity and stability of the flap.

[0058] Furthermore, the reinforcement member is provided with a first reinforcement plate, and the flap is provided with an insertion port for the first reinforcement plate to be inserted, and the inner wall of the insertion port is in contact with the outer surface of the first reinforcement plate.

[0059] By adopting the above solution, the plug interface cooperates with the first reinforcement plate, which facilitates the installation of the reinforcement member.

[0060] Furthermore, the reinforcement member is provided with a second reinforcement plate, and the second reinforcement plate is located on the bottom surface of the flap and fixedly connected thereto.

[0061] By adopting the above solution, the second reinforcement plate is connected to the bottom surface of the flap, which can further improve the performance of the flap in resisting the frontal impact.

[0062] Furthermore, it also includes a chassis shell, the driver, the drive block and the input end are all arranged inside the chassis shell, the chassis shell is provided with an avoidance channel, and the output end passes through the chassis shell and is rotatably connected to the flap to drive the flap to rotate around the rotation axis.

[0063] By adopting the above solution, the chassis shell is provided to protect the drive assembly (i.e., the driver and the drive block) to a certain extent. The avoidance channel provides space for the connecting arm to move upward, so that a chassis shell of a lower height can be used, and the drive assembly and the connecting arm arranged in the chassis shell can also be assembled.

[0064] Furthermore, the opening of the avoidance channel extends from the side surface of the chassis shell to the top surface of the chassis shell.

[0065] By adopting the above solution, the avoidance channel extends to the top of the chassis shell, and the avoidance channel provides space for the connecting arm to move upward, so that a chassis shell of a lower height can be used, and sufficient movement space can be provided for the connecting arm arranged in the chassis shell.

[0066] Furthermore, the flap is an inverted V-shaped slope panel, and a slope high point is provided in the width direction of the flap. In the width direction of the flap, the flap transitions downhill to both sides of the flap with the slope high point as the center, forming an inverted V-shaped slope structure. The drive axis is located near the top of the slope structure, and the rotation axis is located at the bottom of the slope structure.

[0067] By adopting the above solution, the driving axis is arranged higher than the rotating axis. When the connecting arm pushes the flap to turn up, it plays a certain guiding role on the power provided by the connecting arm, further reducing the power required by the connecting arm to push the flap.

[0068] Furthermore, the flap is provided with a hinge along the rotation axis so that the flap is hingedly mounted on an external mounting carrier.

[0069] By adopting the above solution, the hinged member facilitates the hinged connection between the flap and its mounting carrier, wherein the mounting carrier may be the ground or a fixing plate of the parking lock.

[0070] In summary, the parking lock provided by the utility model has the following technical effects:

[0071] 1. Since the driving axis and the rotation axis of the flap are arranged parallel to each other, when the output end of the connecting arm drives the flap to rotate around the rotation axis at the driving axis, a force arm will be formed. The existence of this force arm makes the force required to be applied much smaller when the same torque is output.

[0072] 2. Due to the amplification effect of the torque, the driver can use a low-power driver. That is, under the condition of achieving the same function, the driver has lower energy consumption, more energy-saving, and also reduces the cost. More importantly, the size of the driver is reduced, thereby reducing the size of the parking lock.

[0073] 3. The distance between the drive axis and the rotation axis is no more than a / 2, and the distance that the output end of the connecting arm moves upward is the same as the distance that the drive axis moves upward, ensuring that the distance that the connecting arm moves upward is small, which helps to achieve the small size of the parking lock. In a limited space, a more compact structural design means higher space utilization, making the entire system more compact and efficient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0095] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described and discussed below in conjunction with the accompanying drawings of the present invention. Obviously, what is described here is only a part of the examples of the present invention, not all the examples. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0096] In order to facilitate the understanding of the embodiments of the present utility model, the following will be further explained by taking specific embodiments as examples in conjunction with the drawings, and each embodiment does not constitute a limitation on the embodiments of the present utility model.

[0097] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0098] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0099] Reference Figure 1-Figure 4 As shown, the utility model discloses a parking lock, including: a driving assembly, a connecting arm 3 and a flap 4, wherein the driving assembly includes a driver 1 and a driving block 2, and the driver 1 is transmission-connected with the driving block 2. The flap 4 has a driving axis 41 and a rotation axis 42 which are parallel to each other, the length direction of the flap 4 extends along the rotation axis 42, the width value of the flap 4 is set to a, the distance between the driving axis 41 and the rotation axis 42 is not greater than a / 2, and the flap 4 is provided with a hinge 44 along the rotation axis 42 so that the flap 4 is hingedly mounted on an external mounting carrier. The driver 1 drives the flap 4 to rotate through the driving block 2 and the connecting arm 3 in turn, and the connecting arm 3 has an input end 31 and an output end 32, the input end 31 of the connecting arm 3 is rotationally connected to the driving block 2, and the output end 32 of the connecting arm 3 is rotationally connected to the flap 4. When the driver 1 drives the driving block 2 to move, the driving block 2 drives the input end 31 of the connecting arm 3 to move, and at the same time the input end 31 of the connecting arm 3 rotates relative to the driving block 2, so that the output end 32 of the connecting arm 3 drives the flap 4 to rotate around the rotation axis 42 at the driving axis 41.

[0100] Specifically, the driving assembly adopts the cooperation mode of the driver 1 and the driving block 2, the driver 1 and the driving block 2 are connected in transmission, and the driver 1 can drive the driving block 2 to reciprocate along a straight line, such as a telescopic rod structure, a screw 5 transmission structure or a worm transmission structure, etc., which will not be described in detail here. The flap 4 has a parallel driving axis 41 and a rotation axis 42, and the flap 4 can rotate around the rotation axis 42. The connecting arm 3 has an output end 32 and an input end 31. The input end 31 of the connecting arm 3 is rotationally connected to the driving block 2, and the output end 32 of the connecting arm 3 is rotationally connected to the flap 4. When the driver 1 drives the driving block 2 to move, the driving block 2 drives the input end 31 of the connecting arm 3 to move, and at the same time, the input end 31 of the connecting arm 3 rotates relative to the driving block 2, so that the output end 32 of the connecting arm 3 drives the flap 4 to rotate, and then the connecting arm 3 can control the flipping and resetting of the flap 4 under the drive of the driving assembly. In this embodiment, the specific motion trajectory of the driving component driving the connecting arm 3 is as follows: the driving component drives the input end 31 of the connecting arm 3 to move back and forth in a straight line, so that the output end 32 of the connecting arm 3 pushes upward or pulls downward at a driving axis 41 to rotate the flap 4 around the rotation axis 42. When the driving component drives the input end 31 of the connecting arm 3 to move back and forth in a straight line, the motion trajectory of the input end 31 of the connecting arm 3 is ensured to be fixed and the line is short, so that the space occupied by the input end 31 can be reduced. Assuming that the direction of the driving axis 41 is the length direction of the flap 4, the width value of the flap 4 is a, that is, the length of the width direction of the flap 4 is a, when the flap is in a non-flipped state, in a plane parallel to the ground, the direction perpendicular to the driving axis is the width direction of the flap 4, and the distance between the driving axis 41 and the rotation axis 42 is not greater than a / 2, which is the best. With regard to the rotation of the flap 4 around the rotation axis 42, it can be achieved by setting a rotating shaft or hinge along the rotation axis 42 of the flap 4, which will not be elaborated here.

[0101] In addition, refer to Figure 4-Figure 5 As shown, the flap 4 is provided with a hinge 44 along the rotation axis 42, so that the flap 4 is hingedly mounted on the mounting carrier, and the flap 4 is hingedly connected to the mounting carrier through the hinge 44, which facilitates the assembly of the flap 4. Specifically, the hinge 44 can be a hinge, or an axis hole can be provided on the flap 4, and the hinge 44 structure is formed by passing the rotating shaft through the axis hole, wherein the mounting carrier can be the ground, or the fixing plate 8 of the parking lock.

[0102] The working principle of the above structure is:

[0103] The driving block 2 is connected to the input end 31 of the connecting arm 3 in rotation, and the driver 1 drives the driving block 2 to move, and the driving block 2 drives the input end 31 of the connecting arm 3 to move along the driving direction of the driver 1. In this embodiment, the driver 1 drives the driving block 2 to move in a straight line, and correspondingly, the driving block 2 drives the input end 31 of the connecting arm 3 to reciprocate in a straight line, and the output end 32 of the connecting arm 3 is connected to the driving axis 41 of the flap 4 in a transmission manner, so that the connecting arm 3 drives the flap 4 to rotate around the hinge 44 provided along the rotation axis 42 when driven by the driving block 2, and the flap 4 is flipped up. On the contrary, the driving block 2 drives the input end 31 of the connecting arm 3 to move in the opposite direction to drive the flap 4 to reset.

[0104] The driving axis 41 and the rotation axis 42 of the flap 4 are not on the same straight line. When the output end 32 of the connecting arm 3 drives the flap 4 to rotate around the rotation axis 42 at the driving axis 41, a lever arm will be formed. The existence of this lever arm makes the force required to be applied much smaller when the same torque is output. On the basis of the above effects, the drive assembly can adopt a low-power driver or a reducer with fewer stages of torque increase, that is, when achieving the same function, the energy consumption of the driver is lower, more energy-saving, and the cost is reduced. More importantly, the size of the driver or reducer is reduced, thereby reducing the size of the parking lock. In addition, the distance between the driving axis 41 and the rotation axis 42 is not greater than a / 2, and the distance of the upward displacement of the output end 32 of the connecting arm 3 is the same as the distance of the upward displacement of the driving axis 41, ensuring that the distance of the upward displacement of the connecting arm 3 is small, thereby helping to achieve the small size of the drive assembly. In a limited space, a more compact structural design means higher space utilization, making the entire system more compact and efficient.

[0105] Further, refer to Figure 1 As shown, in order to balance the torque required by the connecting arm 3 and the movement distance requirement, in the width direction of the flap 4, the rotation axis 42 is located on one side of the flap 4, and the drive axis 41 is located between the middle of the flap 4 and the rotation axis 42, that is, between a / 2 of the width a of the flap 4 and the rotation axis 42, thereby ensuring that the output end 32 of the connecting arm 3 can use a smaller force and complete the flipping of the flap 4 in a shorter movement distance.

[0106] Reference Figure 2-Figure 4 As shown, in this embodiment, the connecting arm 3 is tilted, and the output end 32 of the connecting arm 3 is higher than the input end 31 of the connecting arm 3. In the process of the driving component pushing the connecting arm 3, a certain guiding effect is provided on the movement trajectory of the connecting arm 3, so that the movement of the connecting arm 3 is smoother and more powerful. In addition, the above structure also shortens the distance that the driving component needs to drive the input end 31 of the connecting arm 3 to a certain extent, especially when the driving component adopts the screw 5 transmission mode, the requirement for the length of the screw can be reduced, thereby reducing the volume of the parking lock.

[0107] Reference Figure 1 and Figure 4 As shown, in this embodiment, the height of the plane where the driving axis 41 is located is higher than the height of the plane where the rotating axis 42 is located. When the connecting arm 3 pushes the flap 4 to flip up, the above structure plays a certain guiding role on the power provided by the connecting arm 3, further reducing the power required by the connecting arm 3 to push the flap 4. In particular, on the basis of the inclined setting of the connecting arm 3 and the output end 32 of the connecting arm 3 being higher than the input end 31 of the connecting arm 3, the guiding role of the setting of the height of the driving axis 41 being higher than the height of the rotating axis 42 is more obvious, which can significantly reduce the power required by the connecting arm 3 to push the flap 4, thereby reducing the demand for the output power of the drive component, thereby reducing the volume of the parking lock.

[0108] Reference Figure 1-Figure 3 As shown, the linear movement direction of the input end 31 of the connecting arm 3 is perpendicular to the length direction of the flap 4 and parallel to the plane of the mounting carrier of the flap 4. The plane of the mounting carrier of the flap 4 is the plane of the mounting carrier of the flap 4 when it is used and assembled. The fixing plate 8 is a kind of mounting carrier. Through the above structure, the movement space required for the input end 31 of the connecting arm 3 of the parking lock is further reduced, so that the distance between the connecting arm 3 and the flap 4 is smaller, and the structure between the driving assembly, the connecting arm 3 and the flap 4 is more compact, thereby achieving the purpose of reducing the size of the parking lock.

[0109] Reference Figure 1 As shown, in the present embodiment, in the length direction of the flap 4, the connecting arm 3 and the driving assembly (i.e., the driver 1 and the driving block 2) are both located at the same end of the flap 4, that is, the driving assembly and the connecting arm 3 are both arranged on the same side in the length direction of the flap 4, rather than being arranged inside the flap 4 or at the bottom of the flap 4 as in the prior art, thereby achieving the purpose of reducing the overall thickness of the parking lock of the present application.

[0110] Reference Figure 5 and Figure 6 As shown, in some embodiments, the flap 4 is provided with a hinge 44 along the rotation axis 42, so that the flap 4 is hingedly mounted on the mounting carrier, and the flap 4 is hingedly connected to the mounting carrier by the hinge 44, so as to facilitate the assembly of the flap 4. Specifically, the hinge 44 can be a hinge, or a hinge 44 similar to a hinge formed by a rotating shaft passing through the flap 4, wherein the mounting carrier can be the ground, or the fixing plate 8 of the parking lock.

[0111] Reference Figure 7 and Figure 8As shown, further, the driver 1 is transmission-connected with a screw rod 5, the driving block 2 is a nut, the driving block 2 is threadedly connected to the screw rod 5, and the driver 1 drives the screw rod 5 to rotate to drive the driving block 2 to reciprocate along the axial direction of the screw rod 5. By using a smaller screw rod 5 and a smaller driving block 2, it is ensured that the volume of the driving component is reduced while providing a stable power output.

[0112] Reference Figure 7 and Figure 8 As shown, in some embodiments, in order to increase the torque output to the screw rod 5, the driver 1 includes a motor and a reducer 11, the motor is connected to the screw rod 5 through the reducer 11, and the motor, reducer 11 and screw rod 5 are coaxially arranged, which can facilitate the integration of the motor, reducer 11 and screw rod 5 with other components.

[0113] Reference Figure 7 and Figure 8 As shown, in some embodiments, in order to facilitate the installation of the driving assembly, the parking lock further includes a driving installation bracket 7, and the driving assembly is installed on the driving installation bracket 7.

[0114] Specifically, on the basis of the drive assembly adopting the screw rod 5 transmission structure, that is, the drive assembly includes the driver 1, the drive block 2 and the screw rod 5, the drive mounting bracket 7 includes a first bracket plate 71 and a second bracket plate 72, the rotating shaft of the driver 1 is set through the first bracket plate 71, one end of the screw rod 5 is connected to the driver 1, and the other end is assembled on the second bracket plate 72. The first bracket plate 71 and the second bracket plate 72 directly or indirectly support and limit the two ends of the screw rod 5 effectively, which can improve the stability of the screw rod 5 during the transmission process, and when the flap 4 is impacted, the screw rod 5 is not prone to the problem of screw rod 5 deviation. When the driver 1 and the screw rod 5 are connected through the reducer 11, the reducer 11 is connected to the screw rod 5 through the first bracket plate 71.

[0115] In addition, in order to reduce the friction between the screw rod 5 and the drive mounting bracket 7, a bearing 73 or a sleeve can be optionally provided at the assembly point of the screw rod 5 and the second bracket plate 72 to reduce the friction between the screw rod 5 and the second bracket plate 72.

[0116] See also Figure 1 As shown, in this embodiment, in order to make the structure of the parking lock more compact, the movement direction of the driving block 2 is consistent with the width direction of the flap 4, which is equivalent to the driving assembly and the connecting arm 3 being located on the extension of the length direction of the flap 4, thereby making the structure of the parking lock more compact and reducing the footprint of the parking lock. The width direction of the flap 4 is: in the reset state, in a plane parallel to the ground, the direction perpendicular to the driving axis is the width direction of the flap 4

[0117] Reference Figure 2 and Figure 3 As shown, in the present embodiment, in order to facilitate the connection between the flap 4 and the connecting arm 3, a first rotating connecting member 43 is provided at one end of the flap 4 on the driving axis 41 facing the connecting arm 3, and a second rotating connecting member 321 is provided at the output end 32, and the first rotating connecting member 43 is rotatably connected with the second rotating connecting member 321; one of the first rotating connecting member 43 and the second rotating connecting member 321 is an axial hole, and the other is a rotating shaft.

[0118] Specifically, a first rotating connector 43 is provided on one end of the driving axis 41 of the flap 4 facing the connecting arm 3, and a second rotating connector 321 is provided at the output end 32 of the connecting arm 3, wherein the first rotating connector 43 can be one of the shaft hole and the rotating shaft, and the second rotating connector 321 is the other of the shaft hole or the rotating shaft. By inserting the rotating shaft into the shaft hole, the driving block 2 can be rotatably connected to the input end 31, which is convenient for installation, and has a simple structure and is easy to produce, assemble and maintain.

[0119] In addition, refer to Figure 2 As shown, in order to ensure the stable connection between the first rotating connection member 43 and the second rotating connection member 321, the first rotating connection member 43 is a rotating shaft fixedly installed on the flap 4, and the second rotating connection member 321 is an axial hole. One end of the rotating shaft extending out of the flap 4 is inserted into the axial hole and rotatably connected therewith. The rotating shaft is provided with a limiting boss 431, and a limiting step 322 is provided in the axial hole. When the rotating shaft is inserted into the axial hole, the limiting boss 431 cooperates with the limiting step 322. The limiting boss 431 and the limiting step 322 cooperate to prevent the first rotating connection member 43 and the second rotating connection member 321 from being disconnected.

[0120] Reference Figure 2 and Figure 3 As shown, in some embodiments, the driving block 2 is provided with a third rotating connection member 21, and the input end 31 is provided with a fourth rotating connection member 311 that is rotatably connected to the third rotating connection member 21. The third rotating connection member 21 and the fourth rotating connection member 311 are structures that can satisfy that the third rotating connection member 21 and the fourth rotating connection member 311 can rotate with each other, and the driving block 2 drives the input end 31 of the connecting arm 3 to perform linear reciprocating motion.

[0121] Specifically, one of the third rotating connector 21 and the fourth rotating connector 311 is an axial hole, and the other is a rotating shaft, that is, the third rotating connector 21 can be one of the axial hole and the rotating shaft, and the fourth rotating connector 311 is the other of the axial hole or the rotating shaft. Inserting the rotating shaft into the axial hole can realize the rotational connection between the driving block 2 and the input end 31, which is convenient for installation, and has a simple structure and is easy to produce, assemble and maintain.

[0122] Reference Figure 1As shown, in some embodiments, in order to make the structure of the parking lock more compact, the length direction of the connecting arm 3 is set parallel to the movement direction of the driving block 2, the driving block 2 moves along the axial direction of the screw rod 5, and the connecting arm 3 is set between the driving block 2 and the flap 4. By setting the connecting arm 3 parallel to the movement direction of the driving block 2, it can be ensured that the structure of the transmission between the driving block 2 and the flap 4 through the connecting arm 3 is more compact.

[0123] Reference Figure 9-11 As shown, in some embodiments, in order to prevent the driving block 2 from deflecting in the non-moving direction, the parking lock further includes a guide assembly, the guide direction of which is arranged parallel to the moving direction of the driving block 2, and the driving block 2 drives the connecting arm 3 to move along the guide direction of the guide assembly through the guide assembly. The guide assembly limits the movement of the driving block to prevent the driving block from deflecting in the non-moving direction.

[0124] Specifically, the guide assembly includes a first guide member 74 and a second guide member 22 that are slidably matched. The first guide member 74 is arranged between the driving block 2 and the flap 4, and the second guide member 22 is arranged on the side of the driving block 2 facing the first guide member 74. The second guide member 22 arranged on the driving block 2 slides along the first guide member 74. The movement direction of the driving block 2 is limited by the cooperation between the first guide member 74 and the second guide member 22, so as to prevent the driving block 2 from being offset in the non-movement direction.

[0125] Reference Figure 9-11 As shown, in this embodiment, the first guide member 74 is provided with a first slide groove, the second guide member 22 is provided with a first slider, the first slider is slidably arranged along the first slide groove, the third rotating connection member 21 adopts a rotating shaft, the fourth rotating connection member 311 adopts an axial hole, and the second guide member 22 is arranged on the third rotating connection member 21. Since the third rotating connection member 21 passes through the fourth rotating connection member 311, the second guide member 22 is a part of the third rotating connection member 21 passing through the fourth rotating connection member 311. Compared with the split design of the second guide member 22 and the third rotating connection member 21, the second guide member 22 is arranged on the third rotating connection member 21, which is convenient for the production of the drive block 2. In addition, it can also reduce the volume of the drive assembly and the parking lock. For further reference, refer to Figure 12-Figure 15 As shown, the third rotating connector 21 can be reserved in length until it passes through the fourth rotating connector 311. If there is still excess third rotating connector 21, the excess third rotating connector 21 can be milled to form the second guide member 22. This arrangement facilitates the processing of the drive block 2 and can reduce the size of the drive assembly and the parking lock.

[0126] Specifically, the first guide member 74 is assembled on the fixed plate 8 to form a "C"-shaped groove body that opens towards the driving block 2. This groove body is the first sliding groove. The corresponding second guide member 22 is located on the driving block 2 in the direction towards the first sliding groove. The first sliding groove is slidably engaged with the first slider to complete the auxiliary guiding during the movement of the driving block 2.

[0127] Referring to Figure 12-14 As shown, in order to make the connection between the connecting arm 3 and the first guide member 74 more compact, an avoidance groove 312 is provided on one side of the input end 31 of the connecting arm 3 facing the first guide member 74. When the flap 4 is in the flipped-up state, the groove wall of the avoidance groove 312 is in contact with the first guide member 74. The above-mentioned measures thin the connecting arm 3 at the contact part with the first guide member 74, so as to make the structure between the connecting arm 3 and the first guide member 74 more compact, thereby reducing the size of the chassis housing 6 and lowering the height of the parking lock.

[0128] On the basis that the guiding assembly includes the first guide member 74 and the second guide member 22, the guiding assembly further includes a third guide member 75 and a fourth guide member 23 that are slidably engaged. The fourth guide member 23 is provided on the side of the driving block 2 opposite to the input end 31 of the connecting arm 3, that is, the second guide member 22 and the fourth guide member 23 are respectively provided on opposite sides of the driving block 2 in the length direction of the flap 4. The driving block 2 moves along the width direction of the flap 4 with the third guide member 75. Under the restriction of the first guide member 74 and the third guide member 75, it can well restrict the driving block 2 from shifting towards the first guide member 74 and shifting towards the third guide member 75.

[0129] Specifically, the third guide member 75 is provided with a second sliding groove, and the fourth guide member 23 is provided with a second slider. The second slider is slidably arranged along the second sliding groove. The third guide member 75 is assembled on the fixed plate 8 to form a second sliding groove that opens towards the second slider and restricts the second slider from moving in the vertical direction. The second slider is provided with a stepped platform that restricts the second slider from sliding towards the second sliding groove. In the sliding fit between the second slider and the second sliding groove, the second sliding groove restricts the second slider from displacing in the vertical direction, and the stepped platform provided on the second slider is in contact with the upper surface outside the second sliding groove to restrict the second slider from sliding towards the second sliding groove. Combining with the "C"-shaped first sliding groove that restricts the first slider from moving towards the first sliding groove, the effect of restricting the driving block 2 from moving in the vertical direction and restricting the driving block 2 from moving towards both sides (i.e., the direction of the first sliding groove or the second sliding groove) is achieved.

[0130] Referring to Fig.12As shown, in some embodiments, the third guide member 75 is arranged between the first bracket plate 71 and the second bracket plate 72. While providing a limit for the fourth guide member 23, it also provides support for the first bracket plate 71 and the second bracket plate 72, thereby achieving a component (the third guide member 75) that simultaneously satisfies the effect of providing a guide limit for the fourth guide member 23 and providing support for the first bracket plate 71 and the second bracket plate 72, thereby achieving the effect of compressing the volume of the parking lock.

[0131] Reference Figure 14-17 As shown, due to the parking lock, there may be a situation where the vehicle hits the flap 4 in the flipped-up state. During the collision, the connection between the flap 4 and the connecting arm 3 is most susceptible to damage. In view of this, in some embodiments, the flap 4 is provided with a reinforcing member 45 at the first rotating connection member 43. The reinforcing member 45 can strengthen the strength of the flap 4 and the first rotating connection member 43, prevent the flap 4 from being deformed or cracked at the first rotating connection member 43, and improve the strength of the connection between the flap 4 and the first rotating connection member 43, thereby improving the bearing capacity and stability of the flap 4. While protecting the connection between the first rotating connection member 43 and the connecting arm 3, it can effectively prevent the damage of the screw rod 5 and the driving block 2 caused by the flap 4 being hit.

[0132] Specifically, the first rotating connecting member 43 is a rotating shaft, and the reinforcement 45 is provided with an avoidance hole 451 for one end of the rotating shaft to pass through. The reinforcement 45 is assembled on the flap 4, and one end of the rotating shaft passes through the avoidance hole 451 and is assembled on the flap 4. Correspondingly, the second rotating connecting member 321 is an axial hole, and the other end of the rotating shaft is rotatably connected to the axial hole, that is, after the rotating shaft passes through the avoidance hole 451 of the reinforcement 45, it is inserted into the flap 4 and set. After the rotating shaft is subjected to force, it will mainly act on the reinforcement 45, and then be transmitted to the flap 4 through the reinforcement 45, thereby improving the bearing capacity and stability of the flap 4.

[0133] Reference Fig.16 and Fig.17 As shown, in some embodiments, the reinforcement 45 is provided with a first reinforcement plate 452, and the flap 4 is provided with an insertion port 46 for the first reinforcement plate 452 to be plugged in. The inner wall of the insertion port 46 is in contact with the outer surface of the first reinforcement plate 452 to improve the installation method of the reinforcement 45 and the flap 4. The provision of the insertion port 46 corresponding to the first reinforcement plate 452 also facilitates the installation of the reinforcement 45.

[0134] Reference Fig.16 and Fig.17 As shown, in some embodiments, the reinforcement member 45 is provided with a second reinforcement plate 453, and the second reinforcement plate 453 is located on the bottom surface of the flap 4 and fixedly connected thereto. That is, the second reinforcement plate 453 is located on the bottom surface opposite to the front surface of the flap 4, and is in contact with the bottom surface of the flap 4, and when the front surface of the flap 4 is impacted, the performance of resisting the impact of the front surface of the flap 4 can be effectively improved.

[0135] Reference Fig.17 As shown, in this embodiment, the reinforcement member 45 is provided with a first reinforcement plate 452 and a second reinforcement plate 453 at the same time to improve the impact resistance of the flap 4 and increase its service life.

[0136] See also Fig.18 and Fig.19 As shown, in this embodiment, the parking lock further includes a chassis shell 6. Correspondingly, the driving component is arranged inside the chassis shell 6. The chassis shell 6 provides a certain protection effect for the driving component.

[0137] Reference Figure 18-Figure 20 As shown, further, on the basis of setting the chassis shell 6, since the rotation axis 42 of the flap 4 and the driving axis 41 for driving the flap 4 to rotate are not on the same straight line, the connecting arm 3 will move during the rotation of the flap 4. Based on the above situation, the chassis shell 6 is provided with an avoidance channel 61, and the output end 32 passes through the chassis shell 6 and is rotatably connected to the flap 4 to drive the flap 4 to rotate around the rotation axis 42. The avoidance channel 61 provides a basis for the swing of the connecting arm 3. Setting a special avoidance channel 61 can ensure that the internal structure of the chassis shell 6 is installed compactly.

[0138] Among them, it is best that the opening of the avoidance channel 61 extends from the side of the chassis shell 6 to the top surface of the chassis shell 6. When the avoidance channel 61 extends to the top of the chassis shell 6, the avoidance channel 61 provides space for the connecting arm 3 to move upward, so that a chassis shell 6 of a lower height can be used, and the drive assembly and the connecting arm 3 arranged in the chassis shell 6 can also be assembled.

[0139] Specifically, the avoidance channel 61 is provided on the side of the chassis housing 6 facing the flap 4. When the flap 4 is in a non-flipped state, the output end 32 of the connecting arm 3 is located in the avoidance channel 61, which can reduce the height of the flap 4 in a passable state (i.e., non-flipped state);

[0140] When the flap 4 is in the flipped-up state, the output end 32 of the connecting arm 3 extends out from the avoidance channel 61, so that there is no need to set a higher chassis shell 6 to provide the connecting arm 3 with movement space when the chassis shell 6 is not set with the avoidance channel 61, thereby ensuring that the height of the chassis shell 6 itself is not high, thereby reducing the overall height of the parking lock and achieving the purpose of ultra-thin design.

[0141] Reference Figure 1 and Figure 4As shown, in the present embodiment, the flap 4 is an inverted V-shaped slope panel, and a high point of the slope is provided in the width direction of the flap 4. In the width direction of the flap 4, the flap 4 transitions downhill to both sides of the flap 4 with the high point of the slope as the center, forming an inverted V-shaped slope structure. The drive axis 41 is located near the top of the slope structure, and the rotation axis 42 is located at the bottom of the slope structure. Through the above structure, the drive axis 41 is set higher than the rotation axis 42. When the connecting arm 3 pushes the flap 4 to flip up, it plays a certain guiding role on the power provided by the connecting arm 3, thereby further reducing the power required for the connecting arm 3 to push the flap 4.

[0142] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
