The nut is in threaded transmission connection with the lead screw. The two ends of the connecting arm are rotatably connected with the nut and the flap respectively, and the connecting arm is rotatably connected on the opposite side of the pressure surface of the flap.

[0009] The driving mechanism drives the lead screw to rotate to drive the nut to reciprocate along the axial direction of the lead screw, and at the same time, drives the connecting arm to rotate relative to the nut, so that the connecting arm drives the flap to rotate to the closed state or the open state.

[0010] When the flap is rotated to the open state, the connecting arm is supported on the opposite side of the pressure surface of the flap to limit the rotation of the flap under external impact.

[0033] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0034] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] 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 this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0036] See Figures 1-2 and Figures 5-7 This utility model provides an impact-resistant parking lock, comprising: a mounting base 1, on which a drive mechanism, a transmission mechanism 2, and a rotatable flap 3 are mounted. The transmission mechanism 2 includes a lead screw 21, a nut 22, and a connecting arm 23. The drive mechanism is drivenly connected to the lead screw 21, and the nut 22 is threadedly connected to the lead screw 21. The two ends of the connecting arm 23 are rotatably connected to the nut 22 and the flap 3, respectively, and the connecting arm 23 is rotatably connected to the opposite side of the pressure-bearing surface of the flap 3. The drive mechanism drives the lead screw 21 to rotate, thereby causing the nut 22 to reciprocate along the axial direction of the lead screw 21, and simultaneously causing the connecting arm 23 to rotate relative to the nut 22, so that the connecting arm 23 causes the flap 3 to rotate to a closed state or an open state. When the flap 3 is rotated to the open state, the connecting arm 23 is supported on the opposite side of the pressure-bearing surface of the flap 3 to limit the rotation of the flap 3 under external impact.

[0037] Mounting base 1 can be a base plate structure or a parking lock housing structure. It serves as the base of the parking lock, supporting components such as the control box 7, drive mechanism, transmission mechanism 2, and flap 3. The control box 7 is generally located on the side of the flap 3, mounted side-by-side on mounting base 1. The control box 7 contains a battery module and control mechanism, which is electrically connected to the drive mechanism to control its start and stop. The drive mechanism is typically a drive motor, which is connected to the transmission mechanism 2. When the drive motor starts, it drives the lead screw 21 to rotate via its output shaft. A nut 22 is threaded onto the lead screw 21, moving axially along the lead screw 21 as it rotates. This causes the connecting arm 23 to move synchronously, rotating relative to the nut 22, thereby causing the flap 3 to rotate and lift to open, or to lower to close.

[0038] With the side of the flap 3 facing away from the mounting base 1 as the pressure-bearing surface, and the connecting arm 23 rotatably connected to the opposite side of the pressure-bearing surface of the flap 3, the drive mechanism drives the lead screw 21 to rotate, causing the nut 22 to reciprocate along the axial direction of the lead screw 21. Simultaneously, the connecting arm 23 rotates relative to the nut 22, so that when the connecting arm 23 rotates the flap 3 to the open state, the triangular structure formed by the connecting arm 23 supporting the flap 3 and the mounting base 1 improves the impact resistance of the flap 3. This ensures that regardless of whether a car impacts the flap 3 facing or facing away from the mounting base 1, the flap 3 will not rotate to the horizontal closed state, and the flap 3 will not be damaged. When the connecting arm 23 rotates the flap 3 to the closed state, the support of the connecting arm 23 at the bottom of the flap 3 improves the pressure-bearing capacity of the flap 3, ensuring that the flap 3 will not be crushed when a car passes over the parking lock and runs over it. In this way, the parking lock has both impact resistance and pressure resistance, which can prevent it from being damaged by cars and evading payment, and can also prevent it from being run over and damaged by cars after long-term use, thus ensuring the long-term normal use of the parking lock.

[0039] The drive mechanism, lead screw 21, and nut 22 are located on the side of the flap 3 and / or on the opposite side of the pressure-bearing surface of the flap 3. The nut 22 has a connecting block 221 that rotatably engages with the connecting arm 23. The connecting block 221 is located on the opposite side of the pressure-bearing surface of the flap 3. The connecting arm 23 has at least one rotatably connected to the side of the flap 3 facing the mounting base 1. The lead screw 21 and nut 22 are located on the opposite side of the pressure-bearing surface of the flap 3 corresponding to at least one connecting arm 23.

[0040] The drive mechanism can be installed on the side of the flap 3, close to the control box 7, to facilitate electrical connection to the control mechanism and reduce wiring. Alternatively, the drive mechanism can be installed on the opposite side of the pressure-bearing surface of the flap 3. The specific installation position depends on factors such as wiring requirements and the installation position of the transmission mechanism 2. Generally, one drive mechanism is used with one transmission mechanism 2, that is, the output shaft of one drive motor is connected to one lead screw 21 for easy independent control.

[0041] The screw 21 and nut 22 of the transmission mechanism 2 are mainly used to enable the connecting arm 23 to move axially along the screw 21 and rotate relative to the nut 22, so that the flap 3 can be opened or closed. The connection between the nut 22 and the connecting arm 23 is achieved through a connecting block 221 provided on the nut 22. Regardless of whether the screw 21 and nut 22 are located on the side of the flap 3 or on the opposite side of the bearing surface of the flap 3, the connecting arm 23 can be rotatably connected to the opposite side of the bearing surface of the flap 3 through the connecting block 221. Furthermore, depending on the length of the connecting block 221, one connecting block 221 can be rotatably connected to one connecting arm 23, two or more connecting arms 23, etc. The installation position of the connecting arm 23 can also be determined according to the installation position of the screw 21 and nut 22 and the length of the connecting block 221. It can be installed in the middle area or the side areas of the flap 3 facing the mounting base 1. See also... Figure 2 and Figure 8 The nut 22 may have two connecting blocks 221 opposite to each other, so that each connecting block 221 is rotatably connected to a connecting arm 23. The connecting arms 23 on the two connecting blocks 221 may be two independent structures or two supporting arms of the same connecting arm 23. Similarly, the connecting arm 23 may be two independent structures rotatably connected to the flap 3, or two supporting arms of the same connecting arm 23 rotatably connected to the flap 3, or combined into one connecting arm 23 rotatably connected to the flap 3.

[0042] Preferably, two connecting arms 23 are provided, which rotatably connect the flap 3 to the middle area facing the mounting base 1. The lead screw 21 and nut 22 are located on opposite sides of the bearing surface of the flap 3, corresponding to the two connecting arms 23. Two connecting blocks 221 are provided opposite each other in the horizontal direction perpendicular to the axis of the nut 22, and the two connecting arms 23 are rotatably connected to the two connecting blocks 221 respectively. In this structure, the two connecting arms 23 can form two triangular stable structures with the flap 3 and the mounting base 1, and are located in the middle area, which is more conducive to improving the impact resistance and bearing capacity of the flap 3.

[0043] Based on this, refer to Figures 2-3 and Figures 5-6 The mounting base 1 is provided with a guide plate 26 that slides with the nut 22. The guide plate 26 restricts the displacement of the nut 22 on the guide plate 26 perpendicular to its sliding direction. The rotational engagement position of the nut 22 and the connecting arm 23 is between the guide plate 26 and the lead screw 21.

[0044] Specifically, the mounting base 1 has two guide plates 26 extending axially along the lead screw 21. The lead screw 21, nut 22, and connecting arm 23 are all located between the two guide plates 26. The height of the guide plates 26 relative to the mounting base 1 is not lower than that of the nut 22. The guide plates 26 are fixedly mounted on the mounting base 1 and have a guiding function, ensuring that the rotation of the lead screw 21, the axial movement of the nut 22, and the rotational movement of the connecting arm 23 are all within the space between the two guide plates 26, preventing deviation of the movement. Furthermore, the guide plates 26 have a certain protective and shock-absorbing function, preventing the flap 3 from impacting the lead screw 21 and nut 22 when it rotates to the closed state, thereby improving the service life of the transmission mechanism 2.

[0045] Nut 22 is slidably connected to guide plate 26, and guide plate 26 restricts the displacement of nut 22 on guide plate 26 perpendicular to its sliding direction. Based on the sliding connection between guide plate 26 and nut 22, guide plate 26 can both assist the linear movement of nut 22 and restrict its vertical displacement when it is impacted while the flap 3 is open, so as to offset the external impact force, thereby protecting nut 22 and preventing nut 22 from being deformed or damaged.

[0046] The guide plate 26 is provided with a guide member 261, and the nut 22 is adapted to the guide member 261 with a sliding member 222 that has a sliding fit. The guide member 261 restricts the displacement of the sliding member 222 in the direction perpendicular to the sliding direction. When the nut 22 is subjected to impact, the guide member 261 restricts the displacement of the sliding member 222 in the direction perpendicular to its sliding direction, thereby preventing deformation. The guide member 261 can be a groove or a slider, and correspondingly, the sliding member 222 can be a slider or a groove.

[0047] Preferably, the guide member 261 of the guide plate 26 is a groove, and the sliding member 222 of the nut 22 is a slider. During the axial movement of the nut 22 along the screw 21, the sliding member 222 always abuts against the guide member 261. Thus, when the flap 3 is impacted in the open state, the impact force on the flap 3 is transmitted to the connecting arm 23 and simultaneously to the sliding member 222 of the nut 22. Since the guide plate 26 is fixed on the mounting base 1, the impact force can be transmitted to the guide plate 26, the mounting base 1, and the ground, thereby protecting the nut 22 and the screw 21 from damage by the impact force.

[0048] The nut 22 and the connecting arm 23 are rotated together on the side of the sliding member 222 near the lead screw 21. The main body of the nut 22 is connected to the sliding member 222 via the connecting block 221, so that the connecting arm 23, the nut 22 and the guide plate 26 are arranged compactly.

[0049] Based on this, the lead screw 21, nut 22, connecting arm 23, and guide plate 26 are all positioned on the opposite side of the bearing surface, corresponding to the middle area of ​​the flap 3. In this way, the transmission mechanism 2 as a whole supports the opposite side of the bearing surface of the flap 3, further improving the structural strength and impact resistance of the flap 3.

[0050] See Figures 5-7 Both axial ends of the lead screw 21 are rotatably mounted within the fixed seat 24. One axial end of the lead screw 21 passes through its corresponding fixed seat 24 to connect to the drive mechanism. The other axial end of the lead screw 21 is connected to its corresponding fixed seat 24 via a buffer 25. The fixed seat 24 is mounted on the mounting base 1. The fixed seat 24 is bolted to the mounting base 1 and is fixedly connected to the guide plate 26 via bolts 6 and / or pins 8 to support the lead screw 21 without affecting its rotation. After passing through the corresponding fixed seat 24, one axial end of the lead screw 21 connects to the output shaft of the drive motor, allowing the drive motor to rotate the lead screw 21. The other axial end of the lead screw 21 passes into the corresponding fixed seat 24 and abuts against the corresponding fixed seat 24 via the buffer 25. When the flap 3 is impacted in the open state, the connecting arm 23 drives the nut 22 and the lead screw 21 to move relative to the fixed seat 24 along the guide plate 26, pressing against the buffer 25. The buffer 25 provides buffer protection for the flap 3, connecting arm 23, lead screw 21, nut 22, and drive motor, reducing their deformation and damage upon impact. It also buffers the flap 3 when it is in the locked state and subjected to external force. Furthermore, the fixed seat 24 can limit the rotation axis of the lead screw 21 to prevent it from shifting.

[0051] The buffer 25 can be a spring or a rubber component.

[0052] A protective cover 27 is provided above the lead screw 21 and nut 22. The two ends of the protective cover 27 are fixed to two fixing seats 24, and the protective cover 27 is spaced apart from the lead screw 21 and nut 22. The protective cover 27 protects the lead screw 21 and nut 22 from impact by the flip plate 3 without affecting the transmission between the lead screw 21 and nut 22. The protective cover 27 is fixed to the two fixing seats 24 by bolts 6.

[0053] A resilient and expandable sealing sleeve 28 is fitted along the axial direction of the lead screw 21. The inner wall of the sealing sleeve 28 is spaced from the outer wall of the lead screw 21. The sealing sleeve 28 is located at both axial ends of the nut 22 and seals the nut 22 and its corresponding fixing seat 24. Specifically, two resilient and expandable sealing sleeves 28 are fitted along the axial direction of the lead screw 21. The inner walls of both sealing sleeves 28 are spaced from the outer wall of the lead screw 21. The nut 22 is located between the two sealing sleeves 28, and both axial ends of the nut 22 are sealed to one end of its corresponding sealing sleeve 28. The other ends of the two sealing sleeves 28 are sealed to their corresponding fixing seats 24. The sealing sleeves 28 can seal the lead screw 21, preventing rainwater and other substances from corroding the lead screw 21, thus achieving a good waterproof effect and ensuring the accurate, sensitive transmission and safe use of the transmission mechanism 2.

[0054] In addition to the above structure, see [link / reference] Figures 2-4 The mounting base 1 is equipped with a connecting seat 4. The flip plate 3 is rotatably connected to the connecting seat 4 via a main shaft 31, and the connecting arm 23 is rotatably connected to the flip plate 3 via a connecting shaft 32. The central axis of the main shaft 31 is offset from the central axis of the connecting shaft 32. The connecting seat 4 can be a common hinge structure, located below the flip plate 3, providing a concealed effect. The main shaft 31 passes through the flip plate 3 and can be fixedly connected to the flip plate 3 or the connecting seat 4, allowing for rotatable connection between the flip plate 3 and the mounting base 1. The connecting shaft 32 is located within the flip plate 3 and can be fixedly connected to the flip plate 3 or the connecting arm 23, allowing for rotatable connection between the connecting arm 23 and the flip plate 3.

[0055] The central axis of the main shaft 31 and the connecting shaft 32 are offset. When the drive motor drives the lead screw 21 to rotate, the lead screw 21 drives the nut 22 to slide along the guide plate 26. At the same time, the connecting arm 23 slides with the nut 22 and rotates relative to the nut 22. The connecting arm 23 drives the flip plate 3 to flip around the main shaft 31 to the closed or open state. Thus, the drive motor can drive the flip plate 3 to flip with a small torque. Moreover, the movement range of the connecting arm 23 is small, which is conducive to realizing the miniaturization design of the parking lock.

[0056] The flap 3 has a receiving groove 33 at the rotatable engagement point with the connecting arm 23, which allows the flap 3 to avoid the connecting arm 23 during rotation. The connecting shaft 32 is located in the receiving groove 33 and connects to the connecting arm 23. The receiving groove 33 needs to ensure the connection between the connecting arm 23 and the connecting shaft 32, and also needs to provide sufficient space for the movement of the connecting arm 23 so as not to affect the complete closing of the flap 3.

[0057] A limiting member 34 is protruding from the radial outer periphery of the connecting shaft 32. In the direction of the central axis, the limiting member 34 is positioned on both sides of the connecting arm 23. The limiting member 34 can prevent the connecting arm 23 from moving axially relative to the connecting shaft 32, so as to ensure the transmission and rotation effect.

[0058] A torsion spring 5 is fitted on the main shaft 31, with its two ends connected to the mounting base 1 and the flap 3, respectively. When the flap 3 is impacted, it transmits the impact force to the main shaft 31. The main shaft 31 and the torsion spring 5 connected to it can offset the impact force and balance the weight of the flap 3 to prevent it from being closed by impact.

[0059] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
