Description

Technical Field

[0001] This application relates to the field of automotive technology, and in particular to a rear wing adjustment device and a vehicle. Background Technology

[0002] With the rapid development of the automotive industry, cars are going faster and faster, and at the same time, more and more problems are troubling the automotive industry.

[0003] Increased speed significantly increases vehicle drag and lift. Excessive drag leads to a substantial decrease in fuel economy, while excessive lift reduces vehicle handling stability, making it prone to problems such as "floating" and instability at high speeds, seriously affecting driving safety.

[0004] The vehicle-mounted adaptive rear wing can adjust its angle according to the vehicle's speed and the surrounding environment, reducing air resistance and increasing the pressure between the tires and the ground, thereby improving driving safety and stability.

[0005] However, during the driving process, the aerodynamic forces acting on the rear wing surface are constantly changing. Existing technologies make it difficult to adjust the angle of the rear wing in real time while driving, which is not conducive to improving the positional accuracy of the rear wing. Summary of the Invention

Detailed Implementation

[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] In the embodiments of this application, directional terms such as "upper," "lower," and "side" are generally used in the following ways: Figure 1The relative positions shown are based on the given information, and these directional terms are used only to more clearly describe the relationships between structures, not to describe absolute positions. Positions may change when the product is placed in different orientations; for example, "up" and "down" may be interchanged.

[0051] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by those skilled in the art. Some technical terms appearing in the embodiments of this application are described below.

[0052] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0053] like Figures 1 to 7 As shown in the figure, this application provides a tail wing adjustment device, including a tail wing body 1, a support assembly 2, two first transmission assemblies 3 and two second transmission assemblies 4.

[0054] The support component 2 includes a drive component 21 and a rotating shaft 22, which can rotate around its own central axis under the drive of the drive component 21.

[0055] For example, such as Figure 3 As shown, the drive unit 21 and the rotating shaft 22 are connected by gear meshing. The drive unit 21 is a rotary motor. The output shaft of the drive unit 21 is connected to the drive gear 211, and the rotating shaft 22 is connected to the driven gear 212 that meshes with the drive gear 211. When the output shaft of the drive unit 21 rotates, the drive gear 211 drives the driven gear 212 to rotate, thereby causing the rotating shaft 22 to rotate around its own central axis.

[0056] The first transmission component 3 has a mounting hole 321. The rotating shaft 22 passes through the mounting hole 321 and is threadedly connected to the mounting hole 321. The two first transmission components 3 are located on both sides of the midpoint of the axial direction of the rotating shaft 22.

[0057] like Figure 2 As shown, both second transmission components 4 are connected to the tail fin body 1 and can rotate relative to the support component 2. The second transmission components 4 can be threadedly connected to or disconnected from the rotating shaft 22. The two second transmission components 4 are located on the outside of the two first transmission components 3 respectively.

[0058] Specifically, when the rotating shaft 22 is connected to the second transmission assembly 4 on the first side and disengaged from the second transmission assembly 4 on the second side, the tail fin body 1 can rotate in a first direction under the drive of the second transmission assembly 4 on the first side; when the rotating shaft 22 is connected to the second transmission assembly 4 on the second side and disengaged from the second transmission assembly 4 on the first side, the tail fin body 1 can rotate in a second direction under the drive of the second transmission assembly 4 on the second side; when the rotating shaft 22 is connected to both transmission assemblies respectively, the tail fin body 1 is locked. The first direction and the second direction are opposite.

[0059] Specifically, such as Figure 1 As shown, the two first transmission components 3 and the two second transmission components 4 are distributed at intervals along the left and right directions, and the two second transmission components 4 are located outside the first transmission components 3 on the same side, so that the rotating shaft 22 can be connected with the second transmission components 4 after passing through the mounting hole 321.

[0060] The rotating shaft 22 is threadedly connected to the first transmission component 3 and the second transmission component 4 respectively. When the rotating shaft 22 rotates around its own central axis, the threaded engagement enables the rotating shaft 22 to move in its own axial direction, thereby moving closer to or further away from the two second transmission components 4.

[0061] For example, the first direction is counterclockwise and the second direction is clockwise.

[0062] The tail wing adjustment device provided in this application embodiment is configured to connect or disconnect from the tail wing body 1 by setting two second transmission components 4. The second transmission components 4 are configured to be threadedly connected to or disconnected from the rotating shaft 22. The rotating shaft 22 can generate axial movement through threaded engagement under the drive of the drive member 21, thereby connecting with at least one second transmission component 4, thereby driving the tail wing body 1 to rotate, adjusting the angle of the tail wing body 1, and improving the positional accuracy of the tail wing body 1.

[0063] In a further embodiment, each first transmission component 3 includes a first ratchet mechanism 31, and each second transmission component 4 includes a second ratchet mechanism 41. The first ratchet mechanism 31 is connected to the rotating shaft 22, and the second ratchet mechanism 41 can be connected to or disconnected from the rotating shaft 22.

[0064] The first ratchet mechanism 31 and the second ratchet mechanism 41 are coaxially arranged. The stopping directions of the first ratchet mechanisms 31 of the two first transmission components 3 are opposite, the stopping directions of the second ratchet mechanisms 41 of the two second transmission components 4 are opposite, and the stopping directions of adjacent first ratchet mechanisms 31 and second ratchet mechanisms 41 are opposite.

[0065] Specifically, the central axes of the first ratchet mechanism 31, the second ratchet mechanism 41, and the rotating shaft 22 are located on the same straight line, and the rotating shaft 22 can drive the first ratchet mechanism 31 and the second ratchet mechanism 41 to rotate.

[0066] For example, the first ratchet mechanism 31 or the second ratchet mechanism 41 locks when rotating in one direction and locks when moving in the opposite direction. For example, the first direction is from... Figure 1 The first direction is counterclockwise when observing from the rightmost to the leftmost side; the second direction is from... Figure 1 The clockwise direction when observing from the rightmost to the leftmost side Figure 1 The first ratchet mechanism 31 on the left side can rotate normally in the second direction, but locks when rotating in the first direction; Figure 1 The second ratchet mechanism 41 on the left side can rotate normally in the first direction, but locks when rotating in the second direction.

[0067] With this setting, when the tail wing body 1 is not adjusted in angle by the drive component 21, the tail wing body 1 can achieve bidirectional self-locking, limit the tail wing body 1, prevent the tail wing body 1 from rotating, and improve the stability and positional accuracy of the tail wing body 1.

[0068] In a further embodiment, the support assembly 2 further includes a base 23, and the first transmission assembly 3 further includes a first hollow shaft 32 and a first transmission disk 33 fixed to the base 23. The first hollow shaft 32 is coaxially arranged with the rotating shaft 22 and fixedly connected to the first ratchet mechanism 31. The first hollow shaft 32 and the first transmission disk 33 are rotatably connected, and the first hollow shaft 32 has a mounting hole 321, and the first transmission disk 33 has a first receiving groove 331 for accommodating the first ratchet mechanism 31.

[0069] The base 23 is plate-shaped and can be polygonal, elliptical or other irregular shapes. This application does not make any specific limitations.

[0070] like Figure 4 As shown, the base 23 is located at the bottom of the first transmission assembly 3 and the second transmission assembly 4, and the base 23 provides an installation position for the first transmission assembly 3, the second transmission assembly 4 and the support assembly 2.

[0071] The first transmission assembly 3 is fixed to the base 23 via the first transmission disc 33. The second transmission assembly 4 is spaced apart from the base 23 and is suspended relative to the base 23, thereby facilitating connection with the tail fin body 1. Exemplarily, the first transmission disc 33 is fixed to the base 23 using fasteners such as bolts and screws.

[0072] The first hollow shaft 32 has a mounting hole 321 that extends through the first hollow shaft 32 along the axial direction of the rotating shaft 22. For example, the outer peripheral wall of the rotating shaft 22 is provided with an external thread, and the mounting hole 321 is provided with an internal thread that matches the external thread, thereby realizing the threaded engagement between the rotating shaft 22 and the mounting hole 321.

[0073] The first hollow shaft 32 can rotate around its own central axis relative to the first transmission disk 33. Since the first hollow shaft 32 is fixedly connected to the first ratchet mechanism 31, when the first hollow shaft 32 rotates under the drive of the rotating shaft 22, the first ratchet mechanism 31 can also rotate accordingly.

[0074] For example, the first transmission assembly 3 further includes a first bearing cap 34 and a first rolling bearing 35. The first transmission disk 33 has a first bearing mounting hole. The first bearing cap 34 is annular and is installed on the first transmission disk 33 in a direction close to the second transmission assembly 4 on the same side. Figure 4 As shown, the first bearing cap 34 is installed on the left side of the first transmission disc 33 via a threaded connection. The inner ring of the first rolling bearing 35 is installed on the outer wall of the first hollow shaft 32, and the outer ring of the first rolling bearing 35 is installed on the inner wall of the first bearing mounting hole, thereby realizing the rotational connection between the first hollow shaft 32 and the first transmission disc 33. The first bearing cap 34 contacts the outer ring of the first rolling bearing 35, serving as a limiting contact. Optionally, the first rolling bearing 35 is a deep groove ball bearing.

[0075] For example, the first transmission disc 33 has a first receiving groove 331 on the side opposite to the second transmission assembly 4 on the same side, and the first ratchet mechanism 31 is accommodated in the first receiving groove 331.

[0076] In a further embodiment, the first ratchet mechanism 31 includes a drive ratchet 311, a first self-locking block 312, and a first elastic member 313. The drive ratchet 311 has a first connecting hole 3111, and a first hollow shaft 32 is inserted into the first connecting hole 3111. The first self-locking block 312 is rotatably connected to the bottom wall of the first receiving groove 331. One end of the first elastic member 313 is connected to the side wall of the first receiving groove 331, and the other end is connected to the first end of the first self-locking block 312. The second end of the first self-locking block 312 engages with the drive ratchet 311.

[0077] The first self-locking block 312 can be one or more. Figure 5 From Figure 1 The image was obtained when the observation was performed from the far right to the left. Figure 1 A schematic diagram of the first transmission component 3 on the left side, as shown below. Figure 5 As shown, there are multiple first self-locking blocks 312, which are distributed circumferentially around the drive ratchet 311. The drive ratchet 311, the first self-locking blocks 312, and the first elastic element 313 are all located in the first receiving groove 331.

[0078] The drive ratchet 311 is coaxially arranged with the rotating shaft 22. The first connecting hole 3111 passes through the drive ratchet 311 along the axial direction of the rotating shaft 22. The first hollow shaft 32 is inserted into the first connecting hole 3111. The first hollow shaft 32 and the drive ratchet 311 are fixedly connected by means of interference fit, bonding, welding, tenon and mortise connection, etc.

[0079] For example, the first hollow shaft 32 is a stepped shaft with a stepped outer wall. The small diameter end of the first hollow shaft 32 is inserted into the first connecting hole 3111. The stepped surface formed at the connection between the large diameter end and the small diameter end abuts against the end face of the drive ratchet 311, which is beneficial for axially limiting the first hollow shaft 32.

[0080] The first self-locking block 312 has a first rotating hole 3121 extending axially along the rotating shaft 22. Fasteners such as pins pass through the first rotating hole 3121 and are connected to the bottom wall of the first receiving groove 331, thereby realizing the rotational connection between the first self-locking block 312 and the bottom wall of the first receiving groove 331. The first self-locking block 312 can rotate around the central axis of the first rotating hole 3121.

[0081] For example, the first elastic element 313 is a spring, and the first elastic element 313 has elastic deformation capability in its own length direction.

[0082] For example, a first mounting block 3312 protrudes from the side wall of the first receiving groove 331. One end of the first elastic member 313 is connected to the first mounting block 3312 by fasteners such as pins, and the other end of the first elastic member 313 is connected to the first self-locking block 312 by fasteners such as pins. Optionally, as Figure 5 As shown, the first mounting block 3312 is U-shaped.

[0083] By setting the first elastic element 313, the elastic deformation capability of the first elastic element 313 can be used to drive the first self-locking block 312 to reset.

[0084] like Figure 5 As shown, the drive ratchet 311 has multiple ratchet teeth, which are distributed around the central axis of the drive ratchet 311, and the tip of each ratchet tooth is inclined in the same direction.

[0085] The first self-locking block 312 is crescent-shaped and can slide on the back of the ratchet teeth of the driving ratchet 311 or engage between two adjacent ratchet teeth.

[0086] by Figure 5Taking the perspective of the drive ratchet 311 as an example, when the drive ratchet 311 rotates clockwise, the second end of the first self-locking block 312 slides on the back of the ratchet teeth of the drive ratchet 311; when the drive ratchet 311 rotates counterclockwise, the second end of the first self-locking block 312 is inserted between two adjacent ratchet teeth, which locks the drive ratchet 311. At this time, the drive ratchet 311 and the first self-locking block 312 are locked together and the two are relatively stationary.

[0087] In one embodiment, such as Figure 7 As shown, the support assembly 2 also includes two transmission support frames 24 fixed on the base 23, the two transmission support frames 24 being arranged opposite each other along the axial direction of the rotating shaft 22. Figure 4 As shown, the second transmission assembly 4 also includes a second hollow shaft 42, a connector 43, and a second transmission disk 44. Both the second hollow shaft 42 and the connector 43 are coaxially arranged with the rotating shaft 22. One end of the second hollow shaft 42 is rotatably connected to the transmission support frame 24, and the other end is fixedly connected to the connector 43. The connector 43 is drive-connected to the second ratchet mechanism 41. The end of the connector 43 facing away from the second hollow shaft 42 has a second connecting hole 431 for threaded connection with the rotating shaft 22, allowing the rotating shaft 22 to screw into or out of the second connecting hole 431. The second transmission disk 44 has a second receiving groove 441 for accommodating the second ratchet mechanism 41, and the second transmission disk 44 is connected to the tail fin body 1.

[0088] like Figure 7 As shown, both transmission support frames 24 are perpendicular to the base 23, and the two transmission support frames 24 are spaced apart in the left-right direction. The two transmission support frames 24 are symmetrical about a plane perpendicular to the axis of rotation 22. Exemplarily, the two transmission support frames 24 are connected to the base 23 using fasteners such as screws and bolts.

[0089] Optionally, the support assembly 2 further includes at least one pivot support 25, which is mounted on the base 23. For example Figure 7 As shown, there are two shaft support brackets 25, and both shaft support brackets 25 are vertically mounted on the base 23 using fasteners such as screws and bolts.

[0090] Optionally, the pivot support 25 is plate-shaped, and the pivot support 25 can be polygonal, "U"-shaped, semi-circular or other irregular shapes. This application will use the pivot support 25 as an example of a "U"-shaped plate.

[0091] like Figure 4As shown, the second hollow shaft 42 has an inner hole 421 that extends through the second hollow shaft 42 along the axial direction of the rotating shaft 22. The left end of the second hollow shaft 42 is rotatably connected to the transmission support frame 24, and the left end of the connecting piece 43 is inserted into the right end of the inner hole 421 of the second hollow shaft 42. Optionally, the connecting piece 43 and the inner hole 421 are fixedly connected by means of interference fit, bonding, welding, etc., so that the connecting piece 43 and the second hollow shaft 42 move synchronously.

[0092] For example, the connector 43 is a stepped shaft with a stepped outer wall. The small diameter end of the connector 43 is inserted into the inner hole 421. The stepped surface formed at the connection between the large diameter end and the small diameter end abuts against the end face of the second hollow shaft 42, which is beneficial for axially limiting the connector 43.

[0093] For example, the support assembly 2 also includes a second rolling bearing 26. Each transmission support frame 24 is provided with a second bearing mounting hole. A second bearing cap 241 is also provided at the end of the transmission support frame 24 near the second transmission assembly 4. The second bearing cap 241 is installed on the end face of the transmission support frame 24 near the second transmission assembly 4 by means of threaded connection or other means. The second rolling bearing 26 is installed in the second bearing mounting hole. The inner ring of the second rolling bearing 26 is sleeved on the outer wall of the second hollow shaft 42. The outer ring of the second rolling bearing 26 contacts the inner wall of the second bearing mounting hole, thereby realizing the rotational connection between the second hollow shaft 42 and the transmission support frame 24. The second bearing cap 241 contacts the outer ring of the second rolling bearing 26 and plays a limiting role.

[0094] The connecting member 43 is connected to the second ratchet mechanism 41 in a transmission connection, thereby realizing the transmission of power between the connecting member 43 and the second ratchet mechanism 41, and using the connecting member 43 to drive the second ratchet mechanism 41 to rotate.

[0095] like Figure 4 As shown, the right end of the connector 43 has a second connecting hole 431. The second connecting hole 431 can be a through hole or a blind hole. The second connecting hole 431 is provided with an internal thread that matches the external thread of the rotating shaft 22. Therefore, the rotating shaft 22 can be screwed into or out of the second connecting hole 431 with the cooperation of the internal and external threads. For example, when the rotating shaft 22 rotates clockwise, the rotating shaft 22 can move to the left, thereby screwing into the second connecting hole 431 in the second transmission assembly 4 on the left side, and gradually screwing out of the second connecting hole 431 in the second transmission assembly 4 on the right side.

[0096] For example, the second transmission disk 44 has a second receiving groove 441 at one end near the first transmission assembly 3 on the same side.

[0097] The second transmission disk 44 is connected to the tail wing body 1, and the second transmission disk 44 and the tail wing body 1 move synchronously.

[0098] In a further embodiment, the second ratchet mechanism 41 includes a transmission ratchet 411, a second self-locking block 412, and a second elastic member 413; the transmission ratchet 411 has a third connecting hole 4112, and the connector 43 is inserted into the third connecting hole 4112; the second self-locking block 412 is rotatably connected to the bottom wall of the second receiving groove 441, one end of the second elastic member 413 is connected to the side wall of the second receiving groove 441, and the other end is connected to the first end of the second self-locking block 412, and the second end of the second self-locking block 412 cooperates with the transmission ratchet 411.

[0099] The second self-locking block 412 can be one or more. Figure 6 From Figure 1 A schematic diagram of the second transmission component 4 on the left side, obtained when observing from the far right to the left, as shown in the image. Figure 6 As shown, there are multiple second self-locking blocks 412, which are distributed at intervals around the central axis of the transmission ratchet 411. The transmission ratchet 411, the second self-locking blocks 412, and the second elastic element 413 are all located in the second receiving groove 441.

[0100] The transmission ratchet 411 is coaxially arranged with the rotating shaft 22, and the third connecting hole 4112 passes through the transmission ratchet 411 along the axial direction of the rotating shaft 22. The connecting piece 43 is inserted into the third connecting hole 4112.

[0101] The second self-locking block 412 has a second rotating hole 4121 extending axially along the rotating shaft 22. Fasteners such as pins pass through the second rotating hole 4121 and are connected to the bottom wall of the second receiving groove 441, thereby realizing the rotational connection between the second self-locking block 412 and the bottom wall of the second receiving groove 441. The second self-locking block 412 can rotate around the central axis of the second rotating hole 4121.

[0102] For example, the second elastic element 413 is a spring, and the second elastic element 413 has elastic deformation capability in its own length direction.

[0103] For example, a second mounting block 4412 protrudes from the side wall of the second receiving groove 441. One end of the second elastic member 413 is connected to the second mounting block 4412 by a fastener such as a pin, and the other end of the second elastic member 413 is connected to the second self-locking block 412 by a fastener such as a pin. Optionally, as Figure 6 As shown, the second mounting block 4412 is U-shaped.

[0104] By setting the second elastic element 413, the elastic deformation capability of the second elastic element 413 can be used to drive the second self-locking block 412 to reset.

[0105] like Figure 6As shown, the transmission ratchet 411 has multiple ratchet teeth, which are distributed around the central axis of the drive ratchet 311, and the tip of each ratchet tooth is inclined in the same direction.

[0106] The second self-locking block 412 is crescent-shaped and can slide on the back of the ratchet teeth of the transmission ratchet 411 or be engaged between two adjacent ratchet teeth.

[0107] by Figure 6 Taking the perspective of the transmission ratchet 411 as an example, when the transmission ratchet 411 rotates counterclockwise, the second end of the second self-locking block 412 slides on the back of the ratchet teeth of the transmission ratchet 411; when the transmission ratchet 411 rotates clockwise, the second end of the second self-locking block 412 inserts between two adjacent ratchet teeth, which locks the transmission ratchet 411. At this time, the transmission ratchet 411 and the second self-locking block 412 are locked together and remain relatively stationary.

[0108] For example, the second transmission assembly 4 further includes a third bearing cap 46 and a third rolling bearing 47. The second transmission disk 44 has a third bearing mounting hole. The third bearing cap 46 is annular and is mounted on the second transmission disk 44 in a direction away from the first transmission assembly 3 on the same side. Figure 4 As shown, the third bearing cap 46 is installed on the left side of the second transmission disc 44 via a threaded connection. The inner ring of the third rolling bearing 47 is installed on the outer wall of the second hollow shaft 42, and the outer ring of the third rolling bearing 47 is installed on the inner wall of the third bearing mounting hole, thereby realizing the rotational connection between the second hollow shaft 42 and the second transmission disc 44. The third bearing cap 46 contacts the outer ring of the third rolling bearing 47, serving a limiting function. Optionally, the third rolling bearing 47 is a deep groove ball bearing.

[0109] In a further embodiment, the second transmission assembly 4 further includes a telescopic member 45, the connector 43 having a telescopic hole 432 for receiving the telescopic member 45, the telescopic hole 432 extending radially along the connector 43, the transmission ratchet 411 having a slot 4111 communicating with a third connecting hole 4112, and the telescopic member 45 being configured to extend or retract relative to the sidewall of the connector 43, thereby extending into or disengaging from the slot 4111.

[0110] Specifically, the telescopic member 45 extends radially along the connector 43, and the telescopic member 45 can move radially telescopically along the connector 43. When the telescopic member 45 extends relative to the side wall of the connector 43, the telescopic member 45 is inserted into the slot 4111, realizing the circumferential limitation of the transmission ratchet 411 and the connector 43. At this time, the transmission ratchet 411 and the connector 43 are relatively stationary and move synchronously. When the telescopic member 45 retracts relative to the side wall of the connector 43, the telescopic member 45 disengages from the slot 4111, and relative rotation can occur between the transmission ratchet 411 and the connector 43.

[0111] This configuration allows the telescopic component 45 to change the connection state between the connector 43 and the transmission ratchet 411, thereby improving the flexibility of the tail fin adjustment device.

[0112] Furthermore, when the rotating shaft 22 is inserted into the second connecting hole 431, the telescopic member 45 extends into the slot 4111; when the rotating shaft 22 is disengaged from the second connecting hole 431, the telescopic member 45 disengages from the slot 4111.

[0113] Specifically, the telescopic member 45 pops out when the rotating shaft 22 is inserted into the second connecting hole 431, and retracts when the rotating shaft 22 is disengaged from the second connecting hole 431.

[0114] Optionally, the connector 43 is provided with a spring pin structure commonly used in the prior art, and a push rod that is pulsatorically connected to the telescopic member 45 is provided in the second connecting hole 431. The axial movement of the push rod can be converted into the radial movement of the telescopic member 45. When the rotating shaft 22 is inserted into the second connecting hole 431, the push rod is pushed by the rotating shaft 22, thereby causing the telescopic member 45 to pop out; when the rotating shaft 22 is disengaged from the second connecting hole 431, the push rod is reset under the action of the spring, thereby causing the telescopic member 45 to retract.

[0115] Optionally, a position sensor is provided in the second connecting hole 431. The telescopic member 45 is electrically connected to the position sensor. When the position sensor detects that the rotating shaft 22 is inserted into the second connecting hole 431, the position sensor sends a first signal to the telescopic member 45, and the telescopic member 45 pops out after receiving the first signal. When the position sensor detects that the rotating shaft 22 is disengaged from the second connecting hole 431, the position sensor sends a second signal to the telescopic member 45, and the telescopic member 45 retracts after receiving the second signal.

[0116] The telescopic hole 432 may or may not be connected to the second connecting hole 431.

[0117] For example, when the rotating shaft 22 rotates clockwise under the drive of the driving member 21, the rotating shaft 22 gradually rotates to the left towards the first transmission assembly 3 and the second transmission assembly 4. As the rotating shaft 22 continues to move to the left, as... Figure 4 or Figure 8As shown, the rotating shaft 22 extends into the second connecting hole 431 of the connector 43 on the left side, and the telescopic member 45 on the left side extends into the slot 4111. The rotating shaft 22 disengages from the second connecting hole 431 of the connector 43 on the right side. At this time, the rotating shaft 22 drives the drive ratchet 311, the transmission ratchet 411, and the second transmission disc 44 on the left side to rotate clockwise together. At the same time, the second transmission disc 44 on the right side rotates under the drive of the tail fin body 1, thereby enabling the tail fin body 1 to rotate clockwise.

[0118] When the tail fin body 1 rotates clockwise to a specified angle, the rotating shaft 22 rotates counterclockwise under the drive of the drive component 21 and inserts into the second connecting hole 431 of the connector 43 on the right side, as shown. Figure 9 As shown, at this time, both telescopic parts 45 are inserted into the slots 4111. Since the stopping directions of the two drive ratchet 311 are opposite and the stopping directions of the two transmission ratchet 411 are opposite, the second transmission discs 44 on both sides are limited, and the tail wing body 1 cannot rotate, thus achieving bidirectional self-locking.

[0119] When the rotating shaft 22 rotates counterclockwise under the drive of the driving component 21, the rotating shaft 22 gradually rotates towards the first transmission component 3 and the second transmission component 4 on the right. As the rotating shaft 22 continues to move to the right, as... Figure 10 As shown, the rotating shaft 22 extends into the second connecting hole 431 of the connector 43 on the right side, and the telescopic member 45 on the right side extends into the slot 4111. The rotating shaft 22 disengages from the second connecting hole 431 of the connector 43 on the left side. At this time, the rotating shaft 22 drives the drive ratchet 311, the transmission ratchet 411, and the second transmission disc 44 on the right side to rotate counterclockwise. At the same time, the second transmission disc 44 on the left side rotates under the drive of the tail fin body 1, thereby enabling the tail fin body 1 to rotate counterclockwise.

[0120] In one embodiment, a first limiting block 3311 protrudes from the side wall of the first receiving groove 331. The first limiting block 3311 is located between the rotation axis of the first self-locking block 312 and the first elastic member 313 and can abut against the first self-locking block 312.

[0121] The first limiting block 3311 corresponds one-to-one with the first self-locking block 312, for example Figure 5 As shown, the number of first limiting blocks 3311 is the same as the number of first self-locking blocks 312, and each first self-locking block 312 is engaged with a first limiting block 3311.

[0122] By placing the first limiting block 3311 between the rotation axis of the first self-locking block 312 and the first elastic member 313, when the driving ratchet 311 rotates in the locking direction, the first limiting block 3311 can limit the first self-locking block 312, reduce the rotation angle of the first self-locking block 312, and improve the locking effect of the first self-locking block 312 on the driving ratchet 311.

[0123] Optionally, a second limiting block 4411 is provided on the side wall of the second receiving groove 441. The second limiting block 4411 is located between the rotation axis of the second self-locking block 412 and the second elastic member 413 and can abut against the second self-locking block 412.

[0124] The second limiting block 4411 corresponds one-to-one with the second self-locking block 412, for example Figure 6 As shown, the number of second limiting blocks 4411 is the same as the number of second self-locking blocks 412, and each second self-locking block 412 is engaged with a second limiting block 4411.

[0125] By placing the second limiting block 4411 between the rotation shaft of the second self-locking block 412 and the second elastic member 413, the second limiting block 4411 can limit the second self-locking block 412 when the transmission ratchet 411 rotates in the locking direction, thereby reducing the rotation angle of the second self-locking block 412 and improving the locking effect of the second self-locking block 412 on the transmission ratchet 411.
