Description

Technical Field

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

[0002] A parking lock is a mechanical device installed on the ground that can be used to prevent others from occupying a parking space or restrict vehicles from leaving the parking space. Common parking locks are unmanned and automatically controlled, and are particularly suitable for unattended parking management scenarios. Users can scan the code to unlock the car and then drive the vehicle out of the parking space. The lock can also accurately record the parking time and location, and realize networked parking guidance, code scanning parking, vehicle pickup inquiry, electronic self-service payment and other autonomous parking functions.

[0003] Existing parking locks usually consist of a flap assembly and a driving mechanism that drives the flap assembly to flip or lift. When a vehicle enters or exits a parking space, the driving mechanism needs to lower the raised flap toward the mounting seat to remove the flap from blocking the vehicle. However, when the flap is in the raised state, gravel on the ground may be brought to the mounting seat by external factors such as wheels or wind, causing the flap to be blocked by gravel when it is lowered and unable to fit into place with the mounting seat, that is, the flap cannot be reset in place, which will cause the flap's pressure-bearing performance to decrease, and the flap will be easily damaged by being rolled over by the vehicle. It will also cause the drive motor to fail to reset, which in turn causes the drive motor's movement accuracy to decrease, and the drive motor will always be in a power-consuming state, wasting electricity.

[0004] Therefore, there is an urgent need for a flap and a parking lock to overcome the above-mentioned defects. Utility Model Content

[0005] In order to overcome at least one of the defects described in the above-mentioned prior art, one of the objects of the present utility model is to provide a flap which can accommodate sand and gravel on the ground or the mounting seat when it descends toward the ground or the mounting seat of the parking lock, so as to ensure that the flap is reset into place and avoid damage to the flap due to the pressure caused by the pressure of sand and gravel when the flap is under pressure, thereby enhancing the pressure-bearing capacity of the flap.

[0006] The second purpose of the utility model is to provide a parking lock, wherein when the flap descends toward the mounting seat, the supporting surface on the flap can fit into place with the mounting seat, thereby ensuring that the flap is reset into place and enhancing the pressure-bearing capacity of the flap.

[0007] One of the technical solutions adopted by the utility model to solve the problem is:

[0008] A flap, used for a parking lock, comprises a flap body, wherein the flap body has a pressure-bearing surface and a supporting surface opposite to the pressure-bearing surface, and the supporting surface is concavely provided with a recessed portion in the direction of the pressure-bearing surface.

[0009] The flap provided by the utility model has a recessed portion on the supporting surface at the bottom of the flap body, so that when the flap is lowered toward the ground or the mounting seat, the recessed portion of the supporting surface can accommodate sand and gravel on the ground or the mounting seat, thereby avoiding the problem that the flap cannot be completely lowered due to the influence of sand and gravel, and ensuring that the flap can be reset to its proper position; in addition, when the flap is reset to its proper position, when the pressure-bearing surface of the flap is under pressure, it can also avoid the bottom of the flap being damaged by the pressure of sand and gravel, and also enable the vehicle to smoothly enter and exit the parking lock, and avoid the flap from scratching the chassis of the vehicle.

[0010] Furthermore, the support surface can fit closely with the ground or the mounting seat, so that when the flap is under pressure, the pressure can be dispersed through the support surface, thus preventing stress concentration and enhancing the pressure bearing capacity of the flap.

[0011] Furthermore, the flap body includes a support plate, the support surface is located on the bottom surface of the support plate, the support surface is provided with a support portion protruding in a direction away from the pressure-bearing surface, and the support portion is arranged on the outer side of the recessed portion.

[0012] As a result, the pressure in the middle of the flap can be dispersed to the surroundings through the supporting part, reducing stress concentration; and the recessed part accommodates debris such as gravel, which can ensure that the middle of the flap will not be further lifted by the gravel, and can reduce the overall height of the flap, which is more conducive to the vehicle's climbing.

[0013] Furthermore, the recessed portion includes a recessed area and an inclined connecting area, and the inclined connecting area connects the supporting portion and the recessed area.

[0014] Thus, the inclined connection area can make the thickness of the support plate decrease evenly from the support portion to the recessed area, thereby avoiding stress concentration caused by a sudden thickness change between the support portion and the recessed area.

[0015] Furthermore, the flap body includes a guide plate, the guide plate is located above the support plate, and the pressure-bearing surface is located on the top surface of the guide plate; a cavity is formed between the guide plate and the support plate, a reinforcement structure is provided in the cavity, and two ends of the reinforcement structure are respectively connected to the guide plate and the support plate.

[0016] Thus, the cavity can reduce the weight of the flap, and when the flap is lighter, it is beneficial for the drive assembly to use less force to drive the flap up and down, thereby reducing the performance requirements of the drive assembly. A reinforcing structure such as reinforcing ribs is provided in the cavity, and the reinforcing structure can support the guide plate, thereby enhancing the strength and rigidity of the flap.

[0017] Furthermore, the guide plate includes a guide plate segment and a connecting plate segment, the pressure-bearing surface is located on the top surface of the guide plate segment; the connecting plate segment connects the guide plate segment and the support plate; and the connection between the connecting plate segment and the guide plate segment is arc-shaped.

[0018] Thus, the contact surface between the flap body and the vehicle can be prevented from having sharp angles, preventing the chassis from being scratched when the vehicle climbs on the flap. In addition, the connecting plate section and the guide plate section are connected in an arc section, which can reduce the stress concentration at the connection between the connecting plate section and the guide plate section and increase the pressure bearing performance of the flap body.

[0019] Further, the guide plate segment includes a first guide segment and a second guide segment, the first guide segment is arranged between the connecting plate segment and the second guide segment; the first guide segment gradually tilts upward from one end close to the connecting plate segment to one end away from the connecting plate segment; the second guide segment gradually tilts downward from one end close to the first guide segment to one end away from the first guide segment.

[0020] As a result, the flap can be tilted from low to high at the first pressure-bearing section to form a guiding surface, which is conducive to guiding the vehicle to climb forward or backward over the flap.

[0021] Furthermore, the flap body is provided with a first mounting hole for installing the driving shaft of the parking lock at a corresponding position at the connection between the first guide section and the second guide section, and the flap body is provided with a second mounting hole for installing the rotating shaft of the parking lock at a position corresponding to the second guide section. The central axis of the first mounting hole and the central axis of the second mounting hole are parallel to each other and extend along the length direction of the flap body.

[0022] Therefore, the cavity is divided into multiple cavity segments by the reinforcing structure along the width direction, and these cavity segments extend along the length direction of the flap body. Therefore, the cavity segments can be used as axial holes for installing the rotating shaft and the driving shaft, so that the space of the cavity can be fully utilized and the overall volume of the flap can be reduced.

[0023] Furthermore, an anti-slip structure is provided on the pressure-bearing surface.

[0024] Thereby, the contact area between the wheel and the pressure-bearing surface can be increased, thereby preventing the vehicle from slipping when climbing onto the flap body.

[0025] Furthermore, the flap includes an end cover, and the end cover is arranged at the end of the flap body; the bottom of the end cover is arranged flush with the support part.

[0026] Thus, the end cover can support the flap body from both ends, thereby enhancing the pressure bearing capacity of the flap body.

[0027] In summary, the flap provided by the utility model has the following technical effects:

[0028] 1) A recessed portion is provided on the support surface of the flap, which is concavely arranged in the direction of the pressure-bearing surface. When the flap is lowered toward the ground or the mounting seat, the recessed portion can accommodate gravel and other debris on the mounting seat, so that the flap is not blocked by gravel when it is lowered and can be reset to its original position, thereby preventing the flap from being damaged by gravel when it is under pressure, allowing the vehicle to smoothly enter and exit the parking lock, and preventing the flap from scratching the chassis of the vehicle;

[0029] 2) After the flap is reset, the support surface can fit tightly against the ground or the mounting seat, so that the pressure of the flap can be dispersed through the support surface when it is under pressure, thus preventing stress concentration and enhancing the pressure bearing capacity of the flap.

[0030] The second technical solution adopted by the utility model to solve the problem is:

[0031] A parking lock comprises a mounting seat and the flap as described above, wherein the flap is rotatably connected to the mounting seat via a rotating shaft, and the supporting surface is used to abut against the mounting seat when the parking lock is in an unlocked state.

[0032] Therefore, when the flap is lowered toward the mounting seat, the support surface can fit tightly against the mounting seat, so that when the flap is under pressure, the pressure can be dispersed through the support surface, thus preventing stress concentration and enhancing the pressure-bearing capacity of the flap.

[0033] Furthermore, the parking lock also includes a driving assembly, which has a driving arm; the driving arm is rotatably connected to the flap via a driving shaft; when the driving assembly drives the driving arm to move, the driving arm drives the flap to rotate around the rotation axis via the driving shaft.

[0034] Thus, the parking lock can drive the flap to rotate around the rotation axis through the driving arm of the driving assembly to achieve the flipping movement of the flap, thereby switching the locking state and the unlocking state of the parking lock.

[0035] The parking lock provided by the utility model has a recessed portion at the bottom of the flap. When the flap is lowered toward the mounting seat, the recessed portion can accommodate gravel on the mounting seat, so that the flap can be reset in the unlocked state; the reset of the flap can prevent the flap from scratching the chassis of the car. At the same time, the support surface can be closely attached to the mounting seat without being blocked by gravel, and the pressure of the flap can be dispersed through the support surface when the flap is under pressure, so as to prevent stress concentration and improve the pressure bearing performance of the flap.

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.

[0048] Embodiment 1

[0049] See also Figure 1 and Figure 2 The utility model discloses a flap, which is installed on a parking lock. The flap includes a flap body 1. Specifically, the flap body 1 has a pressure-bearing surface 144 and a supporting surface 11, and the pressure-bearing surface 144 and the supporting surface 11 are arranged to be opposite to each other. The pressure-bearing surface 144 is located on the top surface of the flap body 1, and the supporting surface 11 is located on the bottom surface of the flap body 1. A recessed portion 12 is provided on the supporting surface 11, and the recessed portion 12 is recessed toward the direction of the pressure-bearing surface 144. When a wheel rolls over the flap, the pressure-bearing surface 144 contacts the wheel, and the supporting surface 11 contacts the ground or the mounting seat 3 of the parking lock. Figure 6 shown.

[0050] On the basis of this structure, when using the flap of the utility model, the flap can be directly installed on the ground of the parking space, or installed on the mounting seat 3 of the parking space lock, and the flap can be driven to flip through the driving component 4 to achieve lifting and lowering, so that the flap can be used in a locked state for locking the parking space after being raised, or in an unlocked state for unlocking the parking space after being lowered.

[0051] It should be noted that when the flap is raised and in the state of locking the parking lock, the gravel on the ground may be brought to the unlocking and resetting position of the flap by external factors such as wheels or wind, resulting in the flap being blocked by gravel when unlocking and lowering and unable to fit in place with the ground or the mounting seat 3, that is, the flap is not reset in place, which will cause the flap to fail to be completely lowered, which is not conducive to the smooth entry and exit of the vehicle into the parking lock, and the vehicle is also prone to collide with the flap during the process of entering or leaving the parking space, thereby scratching the vehicle chassis. Among them, the support surface 11 fails to fit tightly with the ground or the mounting seat 3 due to the presence of gravel, resulting in uneven contact points or support points at the bottom of the flap; when the pressure-bearing surface 144 of the flap bears pressure, the support surface 11 cannot effectively disperse and withstand the pressure, which is specifically manifested as excessive pressure in some areas (corresponding to the areas with gravel and debris at the bottom), while other areas may be less stressed, resulting in a decrease in the overall pressure-bearing performance of the flap.

[0052] Therefore, the utility model provides a recessed portion 12 on the support surface 11 of the flap, and the recessed portion 12 is recessed toward the pressure-bearing surface 144; when the flap is lowered toward the ground or the mounting seat 3 of the parking lock, the recessed portion 12 can accommodate gravel, so that the flap is not blocked by gravel and can be reset to its original position, ensuring that the flap is completely lowered when the parking lock is unlocked to avoid affecting the entry and exit of vehicles. In addition, the support surface 11 can fit tightly with the ground or the mounting seat 3, so that the pressure of the flap can be dispersed through the support surface 11 when the flap is under pressure, preventing stress concentration and enhancing the pressure-bearing capacity of the flap.

[0053] In this embodiment, Figure 4 As shown, the flap body 1 includes a support plate 13 , and a support surface 11 is located on the bottom surface of the support plate 13 ; wherein the support surface 11 is provided with a support portion 131 and a recessed portion 12 , and the support portion 131 is arranged outside the recessed portion 12 .

[0054] On the basis of this structure, there are several ways to form the recessed portion 12 and the support portion 131: first, the recessed portion 12 can be formed by a portion of the support surface 11 being recessed in the direction of the pressure-bearing surface 144, and the portion of the support surface 11 that is not recessed forms the support portion 131; second, a protrusion can be provided on the support surface 11, specifically, the protrusion is provided in the direction away from the pressure-bearing surface 144, and the protrusion is formed as the support portion 131, and the portion of the support surface 11 without the protrusion is formed as the recessed portion 12; in addition, the recessed portion 12 can be formed by a portion of the support surface 11 being recessed in the direction of the pressure-bearing surface 144, and at the same time, a portion of the support surface 11 is provided in the direction away from the pressure-bearing surface 144 to form the support portion 131.

[0055] Among them, the recessed portion 12 is formed by a portion of the support surface 11 being recessed toward the pressure-bearing surface 144, and when the non-recessed portion of the support surface 11 forms the support portion 131, the overall height of the flap can be reduced, thereby achieving thinning of the overall parking lock device.

[0056] In this embodiment, the recessed portion 12 is preferably formed by a portion of the support surface 11 being recessed in the direction toward the pressure-bearing surface 144, and at the same time, a portion of the support surface 11 is convexly provided in the direction away from the pressure-bearing surface 144 to form a supporting portion 131. This formation method can make the height difference between the recessed portion 12 and the supporting portion 131 large enough to accommodate foreign matter, thereby ensuring the ability of the recessed portion 12 to accommodate foreign matter.

[0057] When the flap is in the unlocked state, the bottom surface of the support plate 13 of the flap is against the ground or the mounting seat 3; when the vehicle rolls over the flap, the support plate 13 is supported and the pressure is dispersed by the support portion 131. When the vehicle climbs and crosses the flap, the pressure is mostly concentrated in the middle of the flap, and the height of the middle part is higher. If there are more gravels and debris under the middle part of the flap, the flap will be further lifted by the gravels, and the stress concentration will be caused in the middle part of the flap.

[0058] Therefore, the recessed portion 12 can be arranged in the middle part of the flap, and the support portion 131 can be arranged on the outside of the recessed portion 12, so that the pressure in the middle part of the flap can be dispersed to the surroundings to reduce stress concentration; and the recessed portion 12 accommodates debris such as gravel, which can ensure that the middle part of the flap will not be further lifted by the gravel, and the overall height of the flap can be reduced, which is more conducive to the climbing of the vehicle.

[0059] Furthermore, if Figure 4 As shown, the recessed portion 12 includes a recessed area 122 and an inclined connection area 121 , wherein the inclined connection area 121 connects the support portion 131 and the recessed area 122 .

[0060] It should be noted that the inclined connection area 121 can make the height of the support plate 13 from the ground increase evenly from the support portion 131 to the recessed area 122, avoiding a large height mutation between the support portion 131 and the recessed area 122 and causing stress concentration. The inclined connection area 121 can also guide the gravel or debris below the side of the support portion 131 close to the recessed area 122 into the recessed portion 12. Under the premise of not affecting the supporting effect of the support plate 13, the inclined connection area 121 can guide as much gravel as possible at the bottom of the support portion 131 into the recessed portion 12, reducing the influence of the gravel on the resetting of the flap.

[0061] In addition, when the flap is under pressure, the support portion 131 supports and disperses the pressure. When the external pressure load is too large, the inclined connection area 121 can deform and tilt toward the ground to absorb part of the pressure, thereby enhancing the pressure-bearing capacity of the support plate 13.

[0062] In some other embodiments, the recessed portion 12 may include a plurality of grooves, and a support platform is provided between the plurality of grooves.

[0063] In this way, the grooves can accommodate gravel on the ground or the mounting seat 3, and the support platforms between the grooves can abut against the ground or the mounting seat 3, and the support platforms can further make the support plate 13 evenly stressed.

[0064] In this embodiment, Figure 1 and Figure 4 As shown, the flap body 1 includes a guide plate 14, and the guide plate 14 is arranged with a spacing relative to the support plate 13, and the guide plate 14 is located above the support plate 13. Among them, the support surface 11 is located on the side of the support plate 13 facing away from the guide plate 14, and the pressure-bearing surface 144 is located on the top surface of the guide plate 14. In addition, a cavity 15 is formed between the guide plate 14 and the support plate 13, and a reinforcement structure 151 is provided in the cavity 15, and the two ends of the reinforcement structure 151 are respectively connected to the guide plate 14 and the support plate 13.

[0065] Based on this structure, the flap body 1 can be an integrally formed structure. Specifically, a piece of aluminum alloy plate can be rolled into a flap body 1 having a cavity 15 structure, and then reinforcing structures 151 such as reinforcing ribs can be welded into the cavity 15; or a flap body 1 having a cavity 15 structure and a reinforcing structure 151 can be made through a casting process.

[0066] The cavity 15 provided in the flap body 1 can reduce the weight of the flap. When the flap is light, it is beneficial for the driving assembly 4 to use less force to drive the flap to rise and fall, thereby reducing the performance requirements of the driving assembly 4. A reinforcing structure 151 such as reinforcing ribs is provided in the cavity 15. The two ends of the reinforcing structure 151 are respectively connected to the guide plate 14 and the support plate 13. The reinforcing structure 151 can support the guide plate 14, thereby enhancing the strength and rigidity of the flap.

[0067] When the vehicle applies pressure to the pressure-bearing surface 144 of the flap, the pressure can be transmitted to the reinforcing structure 151 via the guide plate 14, and then transmitted to the support plate 13 by the reinforcing structure 151, and then dispersed to the ground or the mounting seat 3. Among them, the reinforcing structure 151 can prevent the guide plate 14 from sinking and deforming when under pressure, thereby ensuring that the guide plate 14 is not damaged.

[0068] Furthermore, if Figure 4 As shown, the guide plate 14 includes a guide plate segment 141 and a connecting plate segment 142, wherein the connecting plate segment 142 connects the guide plate segment 141 and the support plate 13, and the pressure-bearing surface 144 is located on the top surface of the guide plate segment 141. The guide plate segment 141 and the support plate 13 are arranged opposite to each other, and the connection between the connecting plate segment 142 and the guide plate segment 141 is arc-shaped.

[0069] Since the flap will inevitably collide with the vehicle when in use, if the connecting plate section 142 and the guide plate section 141 are connected at a right angle, a sharp angle will be formed on the side of the flap; then when the vehicle climbs over the flap body 1 from the side of the flap, the sharp angle on the flap body 1 can easily scratch the chassis of the vehicle. Therefore, the connecting plate section 142 and the guide plate section 141 are connected in an arc section or an arc shape, which can avoid the formation of a sharp angle on the contact surface between the flap body 1 and the vehicle and prevent the vehicle from being scratched. In addition, the connecting plate section 142 and the guide plate section 141 are connected in an arc section, which can reduce the stress concentration at the connection between the connecting plate section 142 and the guide plate section 141, and increase the pressure bearing performance of the flap body 1.

[0070] It should be noted that the connecting plate section 142 can also be set as an arc-shaped plate section, so that the connecting plate section 142, the guide plate section 141 and the support plate 13 are all connected at an arc angle; when the flap is raised, it is not easy to scratch the chassis when the vehicle presses forward or backward over the flap body 1. In addition, when the connecting plate section 142 is set as an arc-shaped plate section, the side of the flap body 1 is curved, which makes it easier for the vehicle to climb over the flap body 1.

[0071] like Figure 4 and Figure 7As shown, a flange 132 extends downward from the side of the support portion 131 close to the connecting plate section 142. When the support portion 131 of the flap abuts against the upper surface of the mounting seat 3, the flange 132 is buckled on the outer edge of the mounting seat 3 to limit the flap in the direction of the wheel's advance, so as to prevent the flap from moving or deflecting and causing the drive shaft 42 that drives the flap to rotate to deflect, thereby increasing the risk of damage to the drive shaft 42 and affecting the rotation of the flap.

[0072] In this embodiment, the guide plate segment 141 includes a first guide segment 1411 and a second guide segment 1412, and the first guide segment 1411 is disposed between the connecting plate segment 142 and the second guide segment 1412. The first guide segment 1411 gradually tilts upward from one end close to the connecting plate segment 142 to one end away from the connecting plate segment 142; the second guide segment 1412 gradually tilts downward from one end close to the first guide segment 1411 to one end away from the first guide segment 1411.

[0073] It should be noted that if Figure 4 and Figure 6 As shown, the first guide section 1411 is close to the free side of the flap body 1, and the second guide section 1412 is close to the connection side of the flap body 1. The flap body 1 is rotatably connected to the ground or the mounting seat 3 through the connection side. The free side of the flap body 1 is close to the connection plate section 142, and the connection side of the flap body 1 is away from the connection plate section 142. The free side of the flap body 1 can be away from or close to the ground during the rotation of the flap body 1, and can be used in a locked state after being away from the ground.

[0074] As a result, the pressure-bearing surface 144 of the flap is first inclined from low to high and then from high to low in the direction from the free side of the flap body 1 to the connecting side of the flap body 1, so that the free side and the connecting side of the guide plate section 141 form inclined surfaces respectively, which is conducive to guiding the vehicle to climb forward or backward over the flap.

[0075] Further, see Figure 4 and Figure 7 The flap body 1 is provided with a first mounting hole 16 for mounting the driving shaft 42 of the parking lock at a corresponding position at the connection between the first guide section 1411 and the second guide section 1412, and the flap body 1 is provided with a second mounting hole 17 for mounting the rotating shaft 43 of the parking lock at a position corresponding to the second guide section 1412, wherein the central axis of the first mounting hole 16 and the central axis of the second mounting hole 17 are parallel to each other and extend along the length direction of the flap body 1.

[0076] It should be noted that in this embodiment, by extending a plurality of reinforcing structures 151 along the length direction of the flap body 1, the cavity 15 is divided into a plurality of cavity segments by the reinforcing structures 151 along the width direction, and these cavity segments all extend along the length direction of the flap body 1, so that the cavity segments can be used to form shaft holes for installing the rotating shaft 43 and the driving shaft 42. In this way, the space of the cavity 15 can be fully utilized and the overall volume of the flap can be reduced.

[0077] In this embodiment, a plurality of anti-slip structures 143 are disposed on the pressure-bearing surface 144 .

[0078] Among them, the upper surface of the guide plate section 141 facing away from the support plate 13 is the pressure-bearing surface 144, and the anti-skid structure 143 thereon can be an anti-skid protrusion or an anti-skid groove. The anti-skid protrusion or the anti-skid groove can increase the contact area between the wheel and the pressure-bearing surface 144, thereby preventing the vehicle from slipping on the pressure-bearing surface 144 of the flap body 1.

[0079] Further, see Figure 1-Figure 3 As shown, the flap also includes an end cover 2, and the end cover 2 is arranged at the end of the flap body 1. Figure 7 The bottom of the end cover 2 is flush with the bottom of the support portion 131 .

[0080] Based on this structure, Figure 3 and Figure 4 As shown, a protruding connection portion 21 is provided on one side of the end cap 2 facing the cavity 15 in the flap, and the protruding connection portion 21 is used to extend into the cavity 15 to achieve a fixed connection between the end cap 2 and the flap body 1. Preferably, the shape of the transverse cross section of the protruding connection portion 21 is set to match the shape of the transverse cross section of the cavity 15 in the flap body 1, so that multiple protruding connection portions 21 can be snapped into the corresponding cavities 15. During assembly, locking members such as screws can also be used to pass through the flap body 1 and the protruding connection portions 21 in sequence to fix the end cap 2 on the flap body 1.

[0081] Since the bottom of the end cover 2 is flush with the bottom of the support portion 131, when the flap body 1 is rolled over by a vehicle, the reinforcing structure 151 in the cavity 15 can support the guide plate 14, and the end cover 2 can support the flap body 1 through the protruding connection portion 21 inserted into the cavity 15. Figure 7 As shown, since the bottom of the end cover 2 is flush with the bottom of the support portion 131 , the end cover 2 can support the flap body 1 together with the support portion 131 to make up for the support gap of the recessed area 122 , thereby enhancing the pressure bearing capacity of the flap body 1 .

[0082] In addition, if Figure 7As shown, when the flap is in the unlocked reset state, the end covers 2 and the support portions 131 on both sides of the flap can surround the recessed portion 12 , thereby effectively preventing foreign matter such as gravel and sand from entering the recessed portion 12 .

[0083] Embodiment 2

[0084] Different from the first embodiment, this embodiment discloses a parking lock, which includes a mounting seat 3 and the flap in the first embodiment. Figure 5 as well as Figure 6 The flap is rotatably connected to the mounting seat 3 via a rotating shaft 43, and the supporting surface 11 of the flap is used to abut against the mounting seat 3 when the parking lock is in an unlocked state.

[0085] Based on this structure, the rotating shaft 43 is arranged on one side of the flap, and a second mounting hole 17 extending along the length direction of the flap body 1 is provided on the flap, and the rotating shaft 43 is installed in the second mounting hole 17 .

[0086] The parking lock has two use states: unlocked and locked, and the switching between the two use states of the parking lock is realized by the rotation connection between the flap and the mounting seat 3. Specifically, when the flap rotates, the side of the flap away from the rotation axis 43 can be away from or close to the mounting seat 3. When the parking lock is in the unlocked state, the flap is lowered and the support surface 11 of the flap is against the mounting seat 3, and the vehicle can press over the flap to enter or exit the parking space; when the parking lock is in the locked state, the flap is raised, and the support surface 11 of the flap is away from the mounting seat 3, and the vehicle cannot enter or exit the parking space.

[0087] It is worth noting that since the support surface 11 of the flap is provided with a recessed portion 12, and the recessed portion 12 is concave toward the back of the support surface 11, when the flap is lowered, the recessed portion 12 can accommodate sand and gravel and other debris on the mounting seat 3, ensuring that when the parking lock is in the unlocked state, the support surface 11 of the flap can be fitted and abutted against the mounting seat 3 to restore the flap to its position.

[0088] It should be noted that, during the lifting of the flap, the gravel on the ground may be brought to the upper surface of the mounting seat 3 by external factors such as wheels or wind. When the flap is lowered, the flap will be blocked by the gravel and cannot fit in place with the mounting seat 3, that is, the flap is not reset in place, which will cause the flap to fail to be completely lowered, and the vehicle is likely to collide with the flap during the process of entering or leaving the parking space, thereby scratching the vehicle chassis. In addition, since the support portion 131 of the flap fails to fit in place with the ground or the mounting seat 3, the flap cannot disperse the pressure to the mounting seat 3 through the support surface 11 when bearing the pressure of the vehicle, and the flap body 1 is easily damaged and destroyed by the vehicle under the action of cyclic stress or local stress concentration. In addition, since the flap is driven to flip by the driving component 4 of the parking lock, if the flap is not reset in place, the driving component 4 that drives the flap to rise and fall cannot be reset, for example, the driving motor cannot be reset, thereby reducing the accuracy of the driving movement; if the driving system does not detect the reset of the driving motor, the driving motor will be in a power consumption state all the time, wasting electric energy.

[0089] Therefore, in this embodiment, a recessed portion 12 is provided on the support surface 11, and the recessed portion 12 can accommodate the gravel on the mounting seat 3, so that the support portion 131 can fit into place with the mounting seat 3, that is, the flap of the parking lock can be reset into place when it is unlocked, so that the drive motor can be reset together with the flap, thereby ensuring the accuracy of the driving movement, and the drive motor enters standby or sleep mode after being reset, saving energy.

[0090] In addition, after the flap is reset, it is not easy to collide with the vehicle, and the vehicle can smoothly enter and exit the parking lock, and the flap is prevented from scratching the vehicle chassis. When the support surface 11 of the flap is tightly fitted with the mounting seat 3, the flap can disperse the pressure to the mounting seat 3 through the support surface 11 when bearing the pressure of the vehicle, thereby preventing stress concentration and enhancing the pressure bearing capacity of the flap.

[0091] Furthermore, the parking lock is further provided with a driving assembly 4, specifically, the driving assembly 4 includes a driving arm 41, and the driving arm 41 is rotatably connected to the flap via a driving shaft 42. When the driving assembly 4 drives the driving arm 41 to move, the driving arm 41 drives the flap to rotate around the rotation axis 43 via the driving shaft 42.

[0092] Based on this structure, a first mounting hole 16 extending along the length direction of the flap body 1 is provided on the flap, and the drive shaft 42 is installed in the first mounting hole 16 .

[0093] The driving assembly 4 can drive the driving arm 41 to move through the motor output shaft and the screw transmission member. During the movement, the driving arm 41 applies force to the flap through the driving shaft 42 to make the flap rotate around the rotation axis 43. After the flap rotates, the free side of the flap away from the rotation axis 43 is away from the mounting seat 3 and raised. Figure 6 At this time, the parking lock can prevent the vehicle from entering or exiting the parking space through the flap; when the free side of the flap is reset to contact with the mounting seat 3 after rotation, refer to Figure 5 , the parking lock is in the closed state and the vehicle can cross the parking lock to enter or exit the parking space.

[0094] 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.
