Description

Technical Field

[0001] This invention relates to the field of parking lock technology, and in particular to an ultra-thin parking lock. Background Technology

[0002] With national development and social progress, automobiles have become increasingly common, leading to a shortage of parking spaces and an imbalance between supply and demand. To strengthen management, some parking facilities, especially roadside parking spaces, often install parking locks. Common parking locks operate in an unattended, automatic control mode. When no car is parked, the lock is closed, not obstructing pedestrian traffic. When a car enters a parking space, the lock automatically recognizes it and locks, restricting movement. The car owner must scan a code to pay before the lock closes, allowing the car to leave.

[0003] Existing parking lock technologies often integrate the power supply unit into the chassis to achieve circuit design goals. However, placing the power supply unit inside the chassis requires reserving space for its installation, thus increasing the chassis's size. An excessively large chassis may interfere with or even cause damage to the car door when it is opened or closed, and it could also pose a tripping hazard to passengers exiting the vehicle. Furthermore, parking locks use a drive mechanism that directly acts on the hinge of the flap to raise and lower it. This requires the drive mechanism to provide greater power output to rotate the flap, necessitating a higher torque driver or multiple stages of reducers to provide the increased power output. This results in a larger drive mechanism, and consequently, a larger parking lock. Summary of the Invention

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides an ultra-thin parking lock, which can solve the problem of the large size of the parking lock caused by the assembly position of the power module and the power requirements of the drive mechanism.

[0005] The technical solution adopted by this invention to solve its problem is:

[0006] An ultra-thin parking lock includes:

[0007] A flap, and a drive mechanism for rotating the flap, wherein the flap has a cavity, a power module is installed in the cavity, the power module is electrically connected to the drive mechanism, and the drive mechanism is located outside the flap; or...

[0008] The flap, the guide plate arranged side by side with the flap, and the drive mechanism for driving the flap to rotate are provided. A cavity is provided in the flap and / or the guide plate. A power module is installed in the cavity. The power module is electrically connected to the drive mechanism. The drive mechanism is located outside the flap and the guide plate.

[0009] The flap has a driving axis and a rotation axis that are parallel to each other. The length of the flap extends along the rotation axis. The width of the flap is set as a. The distance between the driving axis and the rotation axis is not greater than a / 2. The driving mechanism drives the flap to rotate around the rotation axis at the driving axis.

[0010] By adopting the above solution, a cavity is set in the flap and / or guide plate, and the power module is assembled in the cavity. Since the internal space of the flap and / or guide plate is fully utilized, the power module avoids occupying other space or positions on the parking lock, effectively reducing the overall width and / or height of the parking lock, such as reducing the volume of the chassis, thereby achieving a flattened and compact design of the parking lock. Furthermore, the drive mechanism drives the flap to rotate around the rotation axis at the drive axis. Compared to the prior art where the drive mechanism directly acts on the flap's rotation axis, the drive mechanism in this application drives the flap to rotate around the rotation axis at the drive axis, forming a power arm of a certain length. Therefore, the power required to drive the flap to rotate is less, resulting in a smaller drive mechanism and lower cost. In addition, since the distance between the drive axis and the rotation axis is no greater than a / 2, when the drive mechanism pushes the flap to rotate, the component of the drive mechanism used to push the flap to rotate will generate a certain displacement. This displacement distance is the same as the upward displacement distance of the drive axis. That is, the upward displacement distance of the component of the drive mechanism used to push the flap is small, thereby reducing the height of the drive mechanism and further achieving the purpose of the overall ultra-thin design of the parking lock.

[0011] In addition, compared with the prior art where the drive mechanism is located inside the flap, the drive mechanism needs to drive itself while driving the flap to rotate, which leads to increased energy consumption and size of the drive mechanism in the prior art. In contrast, this application places the drive mechanism outside the flap and guide plate, which can effectively reduce the energy consumption and size of the drive mechanism.

[0012] Furthermore, the rotation axis is located on one side of the flap width direction, and the drive axis is located between the middle of the flap and the rotation axis.

[0013] By adopting the above solution, the driving force provided by the drive mechanism and the distance of displacement required by the drive mechanism when driving the flap to rotate are balanced, so as to achieve both the use of a small-volume drive mechanism and the limitation of the distance the drive mechanism follows the flap, thereby realizing the ultra-thin design of the parking lock.

[0014] Furthermore, the height of the plane containing the drive axis is higher than the height of the plane containing the rotation axis.

[0015] By adopting the above solution, the power provided by the connecting arm is guided when the flap is flipped up, thereby further reducing the power required for the connecting arm to push the flap.

[0016] Furthermore, the driving mechanism includes a driving component and a connecting arm. The driving component includes a driver and a driving block. The driver is driven to the driving block to drive the driving block to reciprocate along a straight line. The connecting arm has an input end and an output end. The driving block is rotatably connected to the input end. The output end is rotatably connected to the flap at the driving axis. The driver drives the flap to rotate around the rotation axis in sequence through the driving block and the connecting arm.

[0017] By adopting the above scheme, a drive assembly is used to drive the connecting arm to control the rotation of the flap around the rotation axis. Furthermore, a driver is used to drive the drive block in a linear reciprocating motion, meaning the input end of the connecting arm reciprocates linearly along the direction of the drive block's movement. This greatly limits the space required for the movement of the drive block and the input end of the connecting arm, making the entire drive mechanism structure more compact.

[0018] Furthermore, the drive assembly is located at one end of the flap along its length, and the connecting arm is located between the drive assembly and the flap.

[0019] By adopting the above scheme, the drive component is located at one end of the flip plate in the length direction. In particular, when the length direction of the drive mechanism, the width direction of the flip plate in the unflipped state, and the length direction of the connecting arm are parallel, the drive mechanism and the flip plate are more compact.

[0020] Furthermore, the connecting arm is tilted, and the output end is higher than the input end.

[0021] By adopting the above scheme, the motion trajectory of the connecting arm is guided by the drive component during the process of pushing the connecting arm, thereby making the motion of the connecting arm smoother and more powerful.

[0022] Furthermore, it also includes an auxiliary guide, which includes a first guide located on the opposite side of the drive block, and a second guide that slides with the first guide. Both the first guide and the second guide are arranged along the movement direction of the drive block.

[0023] And / or, the auxiliary guide includes a third guide located on the opposite side of the drive block, and the drive block is provided with a fourth guide that slides with the third guide. Both the third guide and the fourth guide are arranged along the movement direction of the drive block.

[0024] When the auxiliary guide includes the first guide and the third guide, the first guide and the third guide are respectively located on opposite sides of the drive block.

[0025] By adopting the above scheme, the movement trajectory of the drive block can be effectively limited, preventing the drive block from deviating from the guide direction during movement.

[0026] Furthermore, the flap is provided with a first rotating connector at one end of the drive axis facing the connecting arm, and a second rotating connector is provided at the output end, with the first rotating connector and the second rotating connector being rotatably connected.

[0027] By adopting the above scheme, the output end of the connecting arm is rotatably connected to the flap through the rotatable connection of the first rotatable connector and the second rotatable connector.

[0028] Furthermore, the drive block is provided with a third rotating connector, and the input end is provided with a fourth rotating connector that is rotatably connected to the third rotating connector.

[0029] By adopting the above scheme, the input end of the connecting arm is rotated to the drive block through the rotational connection of the third and fourth rotating connectors.

[0030] Furthermore, the first guide member is disposed between the drive block and the flap, the second guide member is disposed in the extension of the third rotating connector, and the extension of the third rotating connector passes through the fourth rotating connector, so that the first guide member and the second guide member are slidably connected.

[0031] By adopting the above solution, compared with the separate design of the second guide and the third rotating connector, the second guide is set on the third rotating connector, which facilitates the production of the drive block. In addition, it can also reduce the size of the drive mechanism.

[0032] Furthermore, the input end of the connecting arm is provided with a clearance groove on the side facing the first guide member.

[0033] By adopting the above solution, the connecting arm is thinned at the contact point between the connecting arm and the first guide member, so that the structure between the connecting arm and the first guide member is more compact, thereby reducing the size of the chassis and lowering the height of the parking lock.

[0034] Furthermore, the driver is coaxially connected to a lead screw, and the driving block is provided with a thread that mates with the lead screw. The driving block is threadedly connected to the lead screw, and the driver drives the lead screw to rotate, thereby causing the driving block to reciprocate along the axial direction of the lead screw.

[0035] By adopting the above scheme, a smaller lead screw and drive block are used to ensure that the size of the drive mechanism is reduced while providing stable power output. The lead screw and drive are set coaxially, which facilitates the integration of the lead screw and drive with other structures. For example, the coaxial lead screw and drive are set on one side of the flap and / or guide plate, making the structure of the flap, lead screw and drive more compact.

[0036] Furthermore, it also includes a chassis housing, the drive mechanism is disposed in the chassis housing, a portion of the drive mechanism extends out of the chassis housing and is connected to the flip plate at the drive axis of the flip plate to drive the flip plate to rotate around the rotation axis.

[0037] By adopting the above solution, the chassis housing provides a certain degree of protection for the drive mechanism.

[0038] Furthermore, the chassis housing is provided with a clearance channel, and the output end of the connecting arm passes through the clearance channel and is connected to the flip plate drive.

[0039] By adopting the above scheme, the clearance channel provides space for the connecting arm to move, which facilitates the connection of the connecting arm to the drive block inside the chassis housing and the first rotating connector outside the chassis housing.

[0040] Furthermore, the clearance channel extends from the side of the chassis housing to the top of the chassis housing, and when the flap rotates, the output end of the connecting arm extends out of the clearance channel or retracts into the clearance channel.

[0041] By adopting the above solution, the clearance channel extends to the top of the chassis housing, providing space for the connecting arm to move upwards. This allows for the use of a lower chassis housing and enables the assembly of the drive mechanism and connecting arm installed inside the chassis housing.

[0042] Furthermore, it also includes a controller, which is located inside the chassis housing. The controller is electrically connected to the drive mechanism and the power module, and the controller and the drive mechanism are arranged side by side.

[0043] By adopting the above solution, compared to the existing technology where the controller is placed inside the flap, placing the controller inside the chassis reduces the weight and thickness of the flap. More importantly, by setting the controller in a long strip shape, with its length parallel to the length of the drive mechanism, the controller and drive mechanism structure inside the chassis is more compact, thereby reducing the size of the chassis.

[0044] Furthermore, the controller has an antenna module, which is communicatively connected to the controller. The side wall of the chassis housing has a clearance opening in the height direction of the chassis housing, and the antenna module is located at the clearance opening.

[0045] By adopting the above solution, a clearance opening is provided in the height direction of the chassis for the installation of the antenna module, which ensures the signal transmission quality of the antenna module. More importantly, it can prevent the chassis and the antenna module from overlapping in the height direction when installed at the same time, thereby effectively reducing the height of the chassis while ensuring the signal transmission quality of the antenna module.

[0046] In summary, the ultra-thin parking lock provided by this invention has the following technical effects:

[0047] 1. By setting cavities in the flap and / or guide plate and assembling the power module inside the cavity, the internal space of the flap and / or guide plate is fully utilized, thereby avoiding the power module occupying other space or position of the parking lock. This can effectively reduce the overall width and / or height of the parking lock, such as reducing the volume of the chassis, and thus realize the flat and small-volume design of the parking lock. This solves the problem of foot blocking and bumping into the car door caused by the height of the chassis, and also facilitates transportation to a certain extent.

[0048] 2. The drive mechanism drives the flap to rotate around the rotation axis at the drive shaft, forming a power arm of a certain length. Compared to the traditional design where the drive mechanism directly acts on the flap's shaft, the structure of this application reduces the power required to drive the flap, lowers the power and size of the actuator in the drive mechanism, and thus allows for a smaller drive mechanism with lower cost. Furthermore, it improves the parking lock's operating range, while also reducing the load on the drive mechanism, thus reducing wear on various components and extending its service life.

[0049] 3. Since the distance between the drive axis and the rotation axis is no greater than a / 2, when the drive mechanism pushes the flap to rotate, the component of the drive mechanism used to push the flap to rotate will generate a certain displacement. This displacement distance is the same as the upward displacement distance of the drive axis. That is, the upward displacement distance of the component of the drive mechanism used to push the flap is small, thereby reducing the height of the drive mechanism and further achieving the purpose of the overall ultra-thin design of the parking lock.

[0050] 4. Compared with the prior art where the drive mechanism is located inside the flap, the drive mechanism needs to drive itself while driving the flap to rotate, which leads to increased energy consumption and size of the drive mechanism. In contrast, this application places the drive mechanism outside the flap and guide plate, which can effectively reduce the energy consumption and size of the drive mechanism.

[0077] Example 1

[0078] Reference Figures 1-3 , Figure 7 and Figure 8 As shown, the present invention discloses an ultra-thin parking space lock, including a flap 21 and a drive mechanism 1 for driving the flap 21 to rotate. The flap 21 has a cavity 23, and a power module 25 is installed in the cavity 23. The power module 25 is electrically connected to the drive mechanism 1. The drive mechanism 1 is located outside the flap 21. The flap 21 has a drive axis 211 and a rotation axis 212 that are parallel to each other. The length direction of the flap 21 extends along the rotation axis 212. The width of the flap 21 is set as a. The distance between the drive axis 211 and the rotation axis 212 is not greater than a / 2. The drive mechanism 1 drives the flap 21 to rotate around the rotation axis 212 at the drive axis 211.

[0079] Example 2

[0080] Reference Figure 1 , Figure 2 , Figures 4-8 As shown, this invention discloses an ultra-thin parking lock, including a flap 21, a guide plate 22 arranged side by side with the flap 21, and a drive mechanism 1 for driving the flap 21 to rotate. A cavity 23 is provided inside the flap 21 and / or the guide plate 22, and a power module 25 is installed inside the cavity 23. The power module 25 is electrically connected to the drive mechanism 1, which is located outside the flap 21 and the guide plate 22. The flap 21 has a drive axis 211 and a rotation axis 212 that are parallel to each other. The length of the flap 21 extends along the rotation axis 212. The width of the flap 21 is denoted as 'a'. The distance between the drive axis 211 and the rotation axis 212 is no greater than a / 2. The drive mechanism 1 drives the flap 21 to rotate around the rotation axis 212 at the drive axis 211.

[0081] Specifically, in the two embodiments described above, Embodiment 1 is an implementation where the parking lock only has a flap 21. Embodiment 2 is an implementation where the parking lock has both a flap 21 and a guide plate 22. In both Embodiment 1 and Embodiment 2, the flap 21 is a moving plate that rotates around a rotation axis 212 driven by the drive mechanism 1. In Embodiment 2, the guide plate 22 is a stationary plate installed on the ground or other mounting carrier. In Embodiment 1, a cavity 23 is provided on the flap 21, and a power module 25 is provided within the cavity 23. In Embodiment 2, a cavity 23 can be provided in both the flap 21 and / or the guide plate 22, and a power module 25 can be provided within the corresponding cavity 23.

[0082] The flip plate 21 is used to flip up to lock the parking space lock when it needs to be locked, and to reset when it needs to be unlocked. The guide plate 22 provides a certain transition guide for the car wheels as they pass over the parking space lock.

[0083] It should be noted that the only difference between Embodiment 1 and Embodiment 2 is the location of the cavity 23 and the location of the power module 25. After considering the different explanations of the flip plate 21 and guide plate 22 mentioned above, the other structures of Embodiment 1 and Embodiment 2 are the same, and the following text will not distinguish between Embodiment 1 and Embodiment 2.

[0084] In this embodiment, both the drive mechanism 1 and the power module 25 are electrically connected to the drive mechanism 1 to supply power to it. The drive mechanism 1 is located outside the flap 21 and the guide plate 22, ensuring that the power requirements of the drive mechanism 1 are lower when driving the flap 21 to rotate. The flap 21 has a parallel drive axis 211 and a rotation axis 212. The length of the flap 21 extends along the rotation axis 212, which is the length direction of the flap 21. Let the width of the flap 21 be a. It is optimal that the distance between the drive axis 211 and the rotation axis 212 is no greater than a / 2 to reduce the movement space required when the drive mechanism 1 drives the flap 21. Regarding the rotation of the flap 21 around the rotation axis 212, the flap 21 is rotatably connected to the ground or other mounting carrier of the parking lock. A hinge can be set on the flap 21 along the rotation axis 212 to realize the rotation of the flap 21 around the rotation axis 212, or a rotating shaft can be passed through the flap 21 along the rotation axis 212 to achieve the purpose of the flap 21 rotating around the rotation axis 212.

[0085] In addition, the drive mechanism 1 is located outside the flap 21 and the guide plate 22. Compared with the prior art where the drive mechanism 1 is located inside the flap 21 or the guide plate 22, the drive mechanism 1 needs to drive itself while driving the flap 21 to rotate. This results in increased energy consumption and increased size of the drive mechanism 1, as well as increased load on the drive mechanism 1 and reduced service life.

[0086] Reference Figure 5 As shown, in embodiment 2, the parking lock is equipped with both a flap 21 and a guide plate 22. The flap 21 is connected to the drive mechanism 1, and the guide plate 22 has a cavity 23 in which the power module 25 is located. By installing the power module 25 in the stationary guide plate 22, compared to placing it in the flap 21, the weight of the flap 21 is reduced, thereby achieving the purpose of driving the flap 21 to rotate using a smaller actuator 111.

[0087] Furthermore, referring to Figure 2 , Figure 7 and Figure 8 As shown, in order to balance the torque required to be output by the drive mechanism 1 with the distance required for the movement of the component (connecting arm 12) along the drive axis 211 of the flap 21, the rotation axis 212 is located on one side of the width direction of the flap 21. That is, the rotation axis 212 is located on the side of the flap 21 near the guide plate 22, and the drive axis 211 is located between the middle of the flap 21 and the rotation axis 212. This ensures that the drive mechanism 1 can complete the flap 21 flipping up in a shorter distance along the drive axis 211 of the flap 21, thereby facilitating the ultra-thin design of the parking lock.

[0088] Reference Figure 2 , Figure 7 and Figure 8 As shown, in this embodiment, the height of the plane containing the drive axis 211 is higher than the height of the plane containing the rotation axis 212. This structure guides the power provided by the connecting arm 12 when it pushes the flap 21 up, further reducing the power required for the connecting arm 12 to push the flap 21. Especially with the connecting arm 12 tilted and its output end 122 higher than its input end 121, the guiding effect of the drive axis 211 being higher than the rotation axis 212 is more pronounced. This significantly reduces the power required for the connecting arm 12 to push the flap 21, thereby reducing the power demand on the drive mechanism 1 and thus reducing the size of the mechanism's transmission.

[0089] Reference Figures 7-10 As shown, in some embodiments, the drive mechanism 1 includes a drive assembly 11 and a connecting arm 12. The drive assembly 11 includes a driver 111 and a drive block 112. The driver 111 and the drive block 112 are connected in a transmission manner to drive the drive block 112 to reciprocate along a straight line. The connecting arm 12 has an input end 121 and an output end 122. The drive block 112 is rotatably connected to the input end 121. The output end 122 is rotatably connected to the flap 21 at the drive axis 211. The driver 111 drives the flap 21 to rotate around the rotation axis 212 in sequence through the drive block 112 and the connecting arm 12.

[0090] Specifically, the driver 111 can be a telescopic rod structure, a worm gear structure, or a lead screw structure, etc., capable of driving the drive block 112 to reciprocate in a straight line; no limitation is made here. Using the driver 111 to drive the drive block 112 to reciprocate in a straight line means that the input end 121 of the connecting arm 12 reciprocates in a straight line along the direction of movement of the drive block 112. This greatly limits the space required for the movement of the drive block 112 and the input end 121 of the connecting arm 12, making the entire drive mechanism 1 more compact.

[0091] In this embodiment, the drive assembly 11 is located at one end of the flap 21 along its length, and the connecting arm 12 is located between the drive assembly 11 and the flap 21. By placing the drive mechanism 1 at one end of the flap 21 along its length, the drive mechanism 1 and the flap 21 are more compact when the length of the drive mechanism 1, the width of the flap 21 in its unflipped state, and the length of the connecting arm 12 are parallel. Placing the connecting arm 12 between the drive assembly 11 and the flap 21 further enhances the compactness between the drive mechanism 1 and the flap 21.

[0092] Reference Figures 7-9 As shown, in this embodiment, the connecting arm 12 is tilted, with the output end 122 higher than the input end 121. During the process of the drive assembly 11 pushing the connecting arm 12, it provides guidance for the movement trajectory of the connecting arm 12, thereby making the movement of the connecting arm 12 smoother and more powerful. Furthermore, the above structure also shortens the distance that the drive mechanism 1 needs to drive the input end 121 of the connecting arm 12 to a certain extent. Especially when the drive mechanism 1 uses a lead screw 13 transmission method, it can reduce the requirement for the length of the lead screw, thereby reducing the size of the movement transmission mechanism.

[0093] Reference Figures 11-13 As shown, in some embodiments, the parking lock further includes an auxiliary guide, which includes a first guide 51 located on one side opposite to the drive block 112. The drive block 112 is provided with a second guide 1121 that slides with the first guide 51. Both the first guide 51 and the second guide 1121 are arranged along the movement direction of the drive block 112. And / or, the auxiliary guide includes a third guide 52 located on the other side opposite to the drive block 112. The drive block 112 is provided with a fourth guide 1122 that slides with the third guide 52. Both the third guide 52 and the fourth guide 1122 are arranged along the movement direction of the drive block 112. When the auxiliary guide includes the first guide 51 and the third guide 52, the first guide 51 and the third guide 52 are respectively located on opposite sides of the drive block 112.

[0094] When the parking lock is equipped with the first guide 51 and the third guide 52 at the same time, it is only necessary to ensure that the first guide 51 and the third guide 52 are located on opposite sides of the drive block 112. Correspondingly, the second guide 1121 and the fourth guide 1122 are also located on opposite sides of the drive block 112. The above structure can limit the movement of the drive block 112 and prevent the drive block 112 from deviating in a non-guided direction during movement.

[0095] In this embodiment, the first guide member 51 and the third guide member 52 are disposed on both sides of the drive block 112 along the drive axis 211. The drive block 112 is provided with a second guide member 1121 corresponding to the first guide member 51 and a fourth guide member 1122 corresponding to the third guide member 52. Since the first guide member 51 and the third guide member 52 need to be fixedly installed, they are arranged along the drive axis 211. The first guide member 51 and the third guide member 52 can be installed on the ground or other installation carrier on which the flip plate 21 is installed. There is no need to set up other installation structures for the installation of the first guide member 51 and the third guide member 52, thereby achieving the purpose of reducing the number of internal parts of the chassis housing 3, and thus reducing the height of the chassis housing 3.

[0096] It should be noted that, for the first guide member 51 and the second guide member 1121, one is a sliding groove and the other is a slider, which is not limited here. Similarly, for the third guide member 52 and the fourth guide member 1122, one is a sliding groove and the other is a slider, which is not limited here.

[0097] In this embodiment, the first guide 51 and the third guide 52 are sliding grooves, and the second guide 1121 and the fourth guide 1122 are sliders disposed on the drive block 112. It is best if the second guide 1121 and the fourth guide 1122 are integrally formed with the drive block 112 to facilitate the assembly of the drive block 112.

[0098] Reference Figure 7 and Figure 8 As shown, in some embodiments, the flap 21 has a first rotating connector 24 at one end of the drive shaft 211 facing the connecting arm 12, and a second rotating connector 1221 at the output end 122. The first rotating connector 24 and the second rotating connector 1221 are rotatably connected.

[0099] Specifically, the drive shaft 211 of the flip plate 21 is provided with a first rotating connector 24 at one end facing the connecting arm 12, and the output end 122 of the connecting arm 12 is provided with a second rotating connector 1221. The first rotating connector 24 can be one of a shaft hole and a rotating shaft, and the second rotating connector 1221 can be the other of a shaft hole or a rotating shaft. The rotating connection between the drive block 112 and the input end 121 can be realized by inserting the rotating shaft into the shaft hole. This makes installation convenient, and the structure is simple, easy to produce, assemble and maintain.

[0100] In some embodiments, the drive block 112 is provided with a third rotating connector 1123, and the input end 121 is provided with a fourth rotating connector 1211 that is rotatably connected to the third rotating connector 1123. The third rotating connector 1123 and the fourth rotating connector 1211 can be configured to rotate relative to each other, and the drive block 112 can drive the input end 121 of the connecting arm 12 to perform linear reciprocating motion.

[0101] Specifically, one of the third rotating connector 1123 and the fourth rotating connector 1211 is a shaft hole and the other is a rotating shaft. That is, the third rotating connector 1123 can be either a shaft hole or a rotating shaft, and the fourth rotating connector 1211 can be either a shaft hole or a rotating shaft. Inserting the rotating shaft into the shaft hole can realize the rotating connection between the drive block 112 and the input end 121, which is convenient for installation, has a simple structure, and is easy to produce, assemble and maintain.

[0102] Reference Figures 14-16 As shown, in this embodiment, with the third rotating connector 1123 being a rotating shaft and the fourth rotating connector 1211 being a shaft hole, the first guide 51 is disposed between the drive block 112 and the flap 21, and the second guide 1121 is disposed on the extension of the third rotating connector 1123. The third rotating connector 1123 is disposed toward the first guide 51, and the extension of the third rotating connector 1123 passes through the fourth rotating connector 1211, so that the first guide 51 and the second guide 1121 are slidably connected.

[0103] Specifically, since the third rotating connector 1123 passes through the fourth rotating connector 1211, the second guide 1121 is a part of the third rotating connector 1123 passing through the fourth rotating connector 1211. Compared to a separate design of the second guide 1121 and the third rotating connector 1123, the second guide 1121 is located on the third rotating connector 1123, which facilitates the production of the drive block 112 and also reduces the size of the movement transmission mechanism. Furthermore, the length of the third rotating connector 1123 can be reserved to allow for an excess portion after passing through the fourth rotating connector 1211. This excess portion of the third rotating connector 1123 can be milled flat to form the second guide 1121. This arrangement facilitates the processing of the drive block 112 and also reduces the size of the movement transmission mechanism.

[0104] Reference Figures 14-16 As shown, in this embodiment, to make the connection between the connecting arm 12 and the first guide member 51 more compact, the input end 121 of the connecting arm 12 is provided with a clearance groove 123 facing the first guide member 51 to prevent interference between the connecting arm 12 and the first guide member 51 during movement. This structure achieves this by thinning the connecting arm 12 at the contact portion with the first guide member 51, resulting in a more compact structure between the connecting arm 12 and the first guide member 51, thereby reducing the size of the chassis housing 3 and lowering the height of the parking lock. Correspondingly, the fourth rotating connector 1211 is located at the clearance groove 123 so that the third rotating connector 1123, which passes through the fourth rotating connector 1211, can contact the first guide member 51.

[0105] Reference Figure 7 and Figure 8 As shown, in this embodiment, the driver 111 is coaxially connected to the lead screw 13, and the drive block 112 is provided with a thread that mates with the lead screw 13. That is, the drive block 112 is a nut that mates with the lead screw 13. The drive block 112 is threadedly connected to the lead screw 13. The driver 111 drives the lead screw 13 to rotate, thereby causing the drive block 112 to reciprocate along the axial direction of the lead screw 13. By using a smaller lead screw 13 and drive block 112, the size of the drive mechanism 1 is reduced while providing stable power output. Furthermore, the driver 111 and the lead screw 13 are coaxially arranged, which facilitates the integration of the lead screw 13 and the driver 111 with other structures. For example, the coaxially arranged lead screw 13 and driver 111 can be located on one side of the flap 21 and / or guide plate 22, making the structure of the flap 21, the lead screw 13, and the driver 111 more compact.

[0106] It should be noted that in this embodiment, the driver 111 includes a motor and a reducer, which are connected in sequence. The reducer is used to increase the torque output by the motor. Based on the above structure, the motor, reducer, and lead screw 13 are similarly arranged coaxially to reduce the size required for the installation of the drive mechanism 1.

[0107] Reference Figure 2 and Figure 9 As shown, in some embodiments, the parking lock also includes a housing 3, and a drive mechanism 1 is disposed in the housing 3. A portion of the drive mechanism 1 extends out of the housing 3 and is connected to the flip plate 21 at the drive axis 211 of the flip plate 21 to drive the flip plate 21 to rotate around the rotation axis 212. The housing 3 provides a certain degree of protection for the drive mechanism 1.

[0108] Correspondingly, in order to facilitate the connection of the connecting arm 12 to the drive block 112 inside the chassis housing 3 and the flap 21 outside the chassis housing 3 (i.e. the first rotating connecting member 24 set on the flap 21), the chassis housing 3 is provided with a clearance channel 31. The connecting arm 12 passes through the clearance channel 31 and is connected to the flap 21 through transmission. The clearance channel 31 can also provide the necessary movement space for the connecting arm 12.

[0109] Reference Figures 17-20 As shown, further, the clearance channel 31 extends from the side of the chassis housing 3 to the top of the chassis housing 3. When the flap 21 rotates, the output end 122 of the connecting arm 12 extends out of the clearance channel 31 or retracts into the clearance channel 31. The clearance channel 31 provides space for the connecting arm 12 to move upward, so that a lower chassis housing 3 can be used, and the drive mechanism 1 and the connecting arm 12 installed inside the chassis housing 3 can also be assembled.

[0110] Specifically, when the flip panel 21 is in the flipped-up state, the output end 122 of the connecting arm 12 extends out from the clearance channel 31, so that there is no need to set a tall chassis 3 to provide the connecting arm 12 with the movement space when the chassis 3 is not set with the clearance channel 31, thereby ensuring that the height of the chassis 3 itself is not high, thereby reducing the overall height of the parking lock and achieving the purpose of ultra-thin design.

[0111] In this embodiment, in addition to the parking lock housing 3, the parking lock also includes a controller 4, which is located inside the housing 3. The controller 4 is electrically connected to the drive mechanism 1 and the power module 25, and the controller 4 and the drive mechanism 1 are arranged side by side.

[0112] Specifically, in order to achieve a more compact design for the parking lock, the housing 3 is located along the length of the flip plate 21. Correspondingly, the drive mechanism 1 and the controller 4 are both located inside the housing 3. The controller 4 is set as a long strip, and its length is parallel to that of the drive mechanism 1. This reduces the space that the housing 3 needs to reserve for installing the controller 4 and the drive mechanism 1, thereby reducing the size of the parking lock.

[0113] Furthermore, based on the controller 4 being elongated and its length parallel to the length of the drive mechanism 1, the lengths of both are further aligned parallel to the width of the flap 21 in its reset state. This maximizes the compactness between the flap 21 and the housing 3, and between the drive mechanism 1 and the controller 4, thereby reducing the overall size of the parking lock. Compared to existing technologies that place the controller 4 within the flap 21 or inside the housing 3, this design reduces the weight and thickness of the flap 21.

[0114] In some embodiments, the controller 4 has an antenna module 41, which is communicatively connected to the controller 4. The side wall of the chassis housing 3 is provided with a clearance opening 32 in the height direction of the chassis housing 3. The antenna module 41 is located at the clearance opening 32. The clearance opening 32 in the height direction of the chassis housing 3 is used for the installation of the antenna module 41, which ensures the signal transmission quality of the antenna module 41. More importantly, it can prevent the simultaneous installation of the chassis housing 3 and the antenna module 41 in the height direction from overlapping. Thus, while ensuring the signal transmission quality of the antenna module 41, the height of the chassis housing 3 is effectively reduced.

[0115] Reference Figure 21 As shown, further, in order to improve the overall integrity of the chassis housing 3, the clearance opening 32 is set to fit optimally against the outer wall of the antenna module 41.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
