DETAILED DESCRIPTION

[0073] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0074] In the present disclosure, unless otherwise stated, the directional words used, such as "upper and lower", are usually defined based on the state of the tail wing linkage mechanism in normal use, and are only for the convenience of describing the present disclosure and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, and a specific orientation structure and operation, and therefore cannot be understood as a limitation on the present disclosure. Optionally, "upper and lower" can be the upper and lower when the tail wing linkage mechanism is in normal use, which can be the same as the upper and lower when the vehicle is in normal driving state. "Inside and outside" refers to the inside and outside of the contour of the corresponding component. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0075] In the description of the present disclosure, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "connect", "connected", and "installed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0076] like Figures 1 to 19As shown, as a first aspect of the present disclosure, the present disclosure provides a tail link mechanism 100, including a base 1, an A link 23, an F link 30 and a bracket 4, the bracket 4 is used to install the tail, the first end of the A link 23 is hinged to the base 1, the second end of the A link 23 is hinged to the bracket 4, and one end of the F link 30 is used for transmission connection with a driving mechanism, for example, see Figure 4 , Figure 6 and Figure 7 As shown, the F link 30 is suitable for transmission connection with the transmission shaft 15 of the driving mechanism through the E link 29. The other end of the F link 30 is hinged to the A link 23, wherein the hinge point between the F link 30 and the A link 23 is located between the first end and the second end of the A link 23.

[0077] In the tail link mechanism 100 provided in the present disclosure, the two ends of the A link 23 are respectively hinged with the bracket 4 and the base 1. By driving the driving mechanism, the A link 23 can be rotated around the corresponding hinge point, thereby driving the bracket 4 to be lifted or retracted, so that the tail link mechanism 100 can have a lifted state, a retracted state, and switch between the lifted state and the retracted state, so that the bracket 4 and the tail are in different positions, such as a lifted position and a retracted position. Moreover, in the present disclosure, the base 1, the A link 23, the F link 30 and the bracket 4 are equivalent to a four-bar structure. The position of the tail is changed by the four-bar structure transmission. The structure is simple, and since the parts required for the tail link mechanism 100 are reduced, it is beneficial to improve the transmission efficiency. When driving the tail under the same conditions, a motor with lower power can be selected, which is also beneficial to reduce the manufacturing cost of the tail link mechanism 100. In summary, the tail link mechanism 100 provided by the present disclosure can reduce the components required for the tail link mechanism 100 while realizing the functions of lifting and retracting the tail, thereby improving the transmission efficiency of the tail link mechanism 100.

[0078] The present disclosure does not limit the specific hinge position of the F link 30 and the A link. In one embodiment of the present disclosure, Figure 1 and Fig.13 As shown, the hinge point between the F link 30 and the A link 23 is located in the middle of the length direction of the A link 23, which is helpful to improve the stability of the F link 30 driving the A link 23 to rotate.

[0079] like Figure 1 and Fig.13As shown, the A link 23 may include a first rod segment 231 and a second rod segment 232, and the first rod segment 231 and the second rod segment 232 are connected at an angle, so that the A link 23 is configured as a bent rod. The first rod segment 231 and the second rod segment 232 of the A link 23 are arranged to be connected at an angle, so that the A link 23 is configured as a bent rod. When the tail link mechanism 100 is in a lifting state or a stowed state, the space occupied by the A link 23 in the height direction of the tail link mechanism 100 (which may be the same as the height direction of the vehicle) is smaller, which is conducive to reducing the space occupied by the tail link mechanism 100.

[0080] like Figure 7 and Fig.13 As shown, the end of the first rod segment 231 away from the second rod segment 232 is the first end of the A link 23, that is, the end of the first rod segment 231 away from the second rod segment 232 is hinged to the base 1, and the end of the second rod segment 232 away from the first rod segment 231 is the second end of the A link 23, that is, the other end of the second rod segment 232 is hinged to the bracket 4. The hinge point between the F link 30 and the A link 23 is located at the connection position of the first rod segment 231 and the second rod segment 232, the first rod segment 231 and the second rod segment 232 are connected at point Q, and the F link 30 is connected to the driving mechanism at point T (as shown in FIG. Fig.13 As shown, point Q and point T are located on both sides of the line connecting the first end and the second end. In other words, by making point Q and point T located on both sides of the line connecting the first end and the second end, the A link 23 can be bent toward the F link 30 and the driving mechanism, and the projections of the F link 30 and the A link 23 on the base 1 are along the length direction of the base 1 (as shown in FIG. Fig.13 The A connecting rod 23 extends in the left-right direction of the drawing, that is, the bent opening of the A connecting rod 23 faces the F connecting rod 30, so that the F connecting rod 30 can be at least partially accommodated in the bent opening of the A connecting rod 23. In this way, it is beneficial to reduce the size of the whole structure of the A connecting rod 23 and the F connecting rod 30 in the length direction of the base 1, thereby reducing the space occupied.

[0081] It is understandable that the T point can be located on the F connecting rod 30 itself, or on an intermediate component connecting the F connecting rod 30 and the driving mechanism, for example, on the E connecting rod 29 connecting the F connecting rod 30 and the transmission shaft 15 of the driving mechanism.

[0082] In addition, during the transition of the tail link mechanism 100 from the stowed state to the raised state, since the F link 30 is hinged at the connection position of the first rod segment 231 and the second rod segment 232, the F link 30 can be driven by the driving mechanism to push the first rod segment 231 and the second rod segment 232 to rotate around the base 1 and the bracket 4 respectively, thereby driving the bracket 4 to rise, and the A link 23 rotates to the supporting position. At the same time, through reasonable design, in the setting such as Fig.13In the embodiment of the present invention, the E link 29 and the F link 30 are collinear to form a self-locking structure. At this time, under the push-up action of the F link 30, the A link 23 will not move along the length direction and height direction of the tail link mechanism 100, thereby forming a larger self-locking structure with the E link 29 and the F link 30, ensuring the stability of the support of the tail link mechanism 100.

[0083] like Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Fig.13 As shown, the tail link mechanism may further include an E link 29, that is, the hinge structure 2 may further include an E link 29, one end of the E link 29 is hinged to the base 1, and the other end of the E link 29 is hinged to one end of the F link 30, and the E link 29 is used to connect with the transmission shaft 15 of the driving mechanism. That is, the F link 30 is connected to the driving mechanism through the E link 29. The E link 29 is suitable for connecting with the transmission shaft 15 of the driving mechanism, and the E link 29 can be configured as a crank. The tail link mechanism 100 can be driven by the driving mechanism to switch between the lifting state and the stowed state. The E link 29 is connected to the driving mechanism and is configured as a crank, so that the E link 29 can drive the F link 30 to perform a planar composite motion of both swinging and moving when rotating, thereby driving the A link 23 to rise or fall, so that the bracket 4 is lifted or stowed.

[0084] In the related art, when the vehicle is driving, the raised rear wing will be affected by the airflow and shake, which will affect the normal operation of the rear wing. Since the rear wing linkage mechanism is in the raised state, the rear wing will be affected by the airflow, which may cause a tendency to move in the direction of continued lifting. In order to ensure that the rear wing can guide the airflow at the rear of the vehicle and increase the downforce, the rear wing needs to be kept in the raised position.

[0085] In view of this, if Figure 1 and Fig.13 As shown, the tail link mechanism 100 may also include a first limiting member 8, which is arranged on the E link 29 and is used to limit the A link 23 from rotating in the direction of the stowed state when in the lifting state, so that the bracket 4 can be maintained in the preset lifting position when in the lifting state. That is, the tail link mechanism 100 is provided with a limiting structure 3, and the limiting structure 3 includes a first limiting member 8, and the position of the A link 23 in the lifting state is limited by the first limiting member 8, so that the A link 23 can be maintained in the preset lifting position and will not rotate easily, thereby improving the stability of the tail link mechanism 100 in the lifting state, which is conducive to ensuring that the tail can play a role in guiding the flow, thereby having the effects of reducing wind resistance and increasing downforce.

[0086] like Figure 1and Fig.13 As shown, the tail link mechanism 100 also includes a B link 21 and a C link 22 that are hinged to each other, the B link 21 is hinged to the bracket 4, and the C link 22 is hinged to the base 1. In the present disclosure, the hinge structure 2 between the base 1 and the bracket 4 may include a B link 21 and a C link 22 in addition to the above-mentioned A link 23. During the lifting or stowing of the bracket 4, the B link 21 or the C link 22 rotates around the corresponding hinge point, and the B link 21 and the C link 22 may also play a supporting role, which is beneficial to improve the load-bearing capacity of the bracket 4 and enhance the reliability and stability of its support of the tail.

[0087] In the present disclosure, the position where the B link 21 and the C link 22 are hinged is not limited. Figure 1 As shown, one end of the B link 21 is hinged to the bracket 4, the other end of the B link 21 is hinged to one end of the C link 22, and the other end of the C link 22 is hinged to the base 1. That is, one end of the B link 21 that is oppositely disposed is hinged to the bracket 4, and the other end that is oppositely disposed is hinged to one end that is oppositely disposed of the C link 22, and the other end that is oppositely disposed of the C link 22 is hinged to the base 1.

[0088] The B link 21 and the C link 22 are hinged at their ends. This arrangement is conducive to reducing the lengths of the B link 21 and the C link 22 when the lifting height is the same, and can also reduce the size of the tail link mechanism 100 along the length direction of the bracket 4 when the tail link mechanism 100 is in the stowed state, further reducing the occupied space of the tail link mechanism 100.

[0089] like Figures 1 to 5 The tail wing linkage mechanism 100 may further include a second limit member 31, that is, the limit structure 3 may further include a second limit member 31. When the tail wing linkage mechanism 100 is in the lifting state, the second limit member 31 is used to limit the rotation of the B link 21 and / or the C link 22, so that the bracket 4 can be maintained in the preset lifting position when in the lifting state.

[0090] The second limiter 31 is used to limit the rotation of the B-link 21 and / or the C-link 22, so that the bracket 4 can be maintained in the preset lifting position when in the lifting state. That is, the second limiter 31 is used to limit the rotation of any one of the B-link 21 and the C-link 22. For example, the position of the B-link 21 in the lifting state is limited by the second limiter 31, so that the B-link 21 will not rotate in the direction of continuing lifting under the drive of the tail wing, thereby ensuring the stability of the tail wing linkage 100 in the lifting state. Thereby, the effects of reducing wind resistance, increasing downforce, etc. are achieved, and finally the bracket 4 can be maintained in the preset lifting position when in the lifting state. When the bracket 4 is maintained in the lifting position, the tail wing can be maintained in the lifting position.

[0091] The present disclosure does not limit the arrangement position of the second limiting member 31. In an embodiment provided in the present disclosure, Figure 1 , Figure 2 and Figure 4 As shown, a second stopper 31 is provided on the A link 23. During the transformation of the tail link mechanism 100 from the stowed state to the lifted state, the B link 21 can rotate around the hinge point between it and the bracket 4, and the C link 22 can rotate around the hinge point between it and the base 1, and the B link 21 and the C link 22 gradually approach the co-linear state from the folded state; at the same time, since the two ends of the A link 23 are respectively hinged to the bracket 4 and the base 1, the two ends of the A link 23 rotate around the hinge points between it and the bracket 4 and the base 1, and the second stopper 31 is provided on the A link 23 and can rotate together with the A link 23.

[0092] like Figure 4 As shown, when the bracket 4 rises to a preset height, the driving mechanism can stop running, the A link 23 is in a lifted state, and the second limit member 31 abuts against the B link 21 to limit the position of the B link 21; at the same time, due to the limitation of the driving mechanism stopping operation, the A link 23 cannot easily return to the retracted state. By utilizing the self-locking property of the driving mechanism, the position of the B link 21 is further limited by the second limit member 31 to ensure the stability of the tail wing linkage mechanism 100.

[0093] The present application does not limit the specific structure of the second limiting member 31. In one embodiment of the present disclosure, Figure 4 and Figure 5 As shown, one end of the second stopper 31 is connected to the A connecting rod 23, and the other end extends toward the thickness direction of the base 1. The A connecting rod 23 and the B connecting rod 21 are arranged in a spaced relationship along the thickness direction, that is, the direction in which the A connecting rod 23 and the B connecting rod 21 are arranged in a spaced relationship is the thickness direction of the base 1. Since the A connecting rod 23 and the B connecting rod 21 need to rotate simultaneously during the state conversion process of the tail wing linkage mechanism 100, in order to prevent interference during the rotation process, the A connecting rod 23 and the B connecting rod 21 are arranged in a spaced relationship along the thickness direction of the base 1, so that the A connecting rod 23 and the B connecting rod 21 can each rotate in their own rotation plane. At the same time, the second stopper 31 is connected to the A connecting rod 23 and extends toward the thickness direction of the base 1, and can stop the B connecting rod 21 under the drive of the A connecting rod 23, thereby conveniently limiting the position of the B connecting rod 21 in the lifting state.

[0094] In the present disclosure, the second position limiter 31 can be connected to the A connecting rod 23 in any appropriate manner, and the two can be an integral part or a separate part, and the present disclosure does not limit this. Optionally, the second position limiter 31 is integrally formed with the A connecting rod 23, that is, the second position limiter 31 and the A connecting rod 23 are an integral part. Compared with the method of processing and then connecting separately, the second position limiter 31 is integrally formed with the A connecting rod 23, and the connection firmness and matching accuracy of the second position limiter 31 and the A connecting rod 23 are higher, and the structural abnormal noise caused by improper assembly can be reduced. At the same time, it is also convenient for processing.

[0095] In order to reduce structural abnormal noise during the rotation of the hinged structure 2, optionally, as Figure 5 As shown, the part of the second stopper 31 that is used to contact the B-link 21 is provided with a flexible coating layer 32. Since the second stopper 31 and the B-link 21 will come into contact with each other when the tail wing linkage mechanism 100 is transformed between different states, the flexible coating layer 32 is provided on the second stopper 31 to provide a buffer when the second stopper 31 and the B-link 21 are in contact, thereby reducing the abnormal sound caused by the collision between the second stopper 31 and the B-link 21, playing a noise reduction role, and further improving the user's riding experience. In addition, by providing the flexible coating layer 32, it is possible to avoid damage to the B-link 21 when the second stopper 31 hits the B-link 21.

[0096] Alternatively, if Figure 3 , Figure 5 and Figure 6 As shown, the tail link mechanism 100 also includes a third limiter 33, that is, the limiter structure 3 may also include a third limiter 33, and the third limiter 33 is suitable for limiting the C link 22 from rotating in the direction of continuing to lift in the lifting state. Since the C link 22 provides support for the B link 21 on the one hand, and the C link 22 also rotates with the B link 21 on the other hand during the rotation of the B link 21, the third limiter 33 is provided, and the range of motion of the B link 21 can be further limited by the C link 22, so that the B link 21 will not rotate in the direction of continuing to lift under the drive of the tail, thereby ensuring the stability of the tail link mechanism 100 in the lifting state. Thereby achieving the effects of reducing wind resistance and increasing downforce.

[0097] The present disclosure does not limit the location of the third position-limiting member 33. Optionally, Figure 6 As shown, the third stopper 33 is disposed on the base 1. Since the C-link 22 rotates around the hinge point between the C-link 22 and the base 1 during the rotation process, the third stopper 33 is disposed on the base 1, and the C-link 22 can be stopped and limited on the rotation path of the C-link 22, thereby limiting the range of motion of the B-link 21 and improving the stability of the tail wing linkage mechanism 100.

[0098] In the present disclosure, the third position limiter 33 can be connected to the base 1 in any appropriate manner, and the two can be an integral part or a separate part, and the present disclosure does not limit this. Optionally, the third position limiter 33 is integrally formed on the base 1, that is, the third position limiter 33 and the base 1 are an integral part. Compared with the method of processing and then connecting separately, the third position limiter 33 is integrally formed on the base 1, and the connection firmness and matching accuracy of the third position limiter 33 and the base 1 are higher, and the structural abnormal noise caused by improper assembly can be reduced. At the same time, it is also convenient for processing.

[0099] In order to reduce structural abnormal noise during the rotation of the hinged structure 2, optionally, as Figure 3 , Figure 5 and Figure 6 As shown, the portion of the third stopper 33 that is used to contact the C-link 22 is provided with a flexible coating layer 32. Since the third stopper 33 and the C-link 22 will come into contact with each other when the tail wing linkage mechanism 100 is transformed between different states, the flexible coating layer 32 provided on the third stopper 33 can provide a buffer when the third stopper 33 and the C-link 22 are in contact, thereby reducing the abnormal sound caused by the collision between the third stopper 33 and the C-link 22, playing a noise reduction role, and further improving the user's riding experience. In addition, by providing the flexible coating layer 32, it is possible to avoid damage to the C-link 22 when the third stopper 33 hits the C-link 22.

[0100] In order to improve the supporting effect of the hinge structure 2, optionally, as Figure 1 As shown, the A link 23 is hinged to the bracket 4 at a first hinge point 24 , and the B link 21 is hinged to the bracket 4 at a second hinge point 25 . The first hinge point 24 and the second hinge point 25 are respectively located at two ends of the bracket 4 in the length direction.

[0101] It can be understood that, here, the first hinge point 24 and the second hinge point 25 are respectively located at the two ends of the length direction of the bracket 4, which can refer to the first hinge point 24 and the second hinge point 25 being respectively located at the two ends of the length direction of the bracket 4, and the two ends include the end faces of the two ends of the length direction of the bracket 4, and also include the parts close to the end faces. In other words, the distance between the first hinge point 24 and the end face of one end of the bracket 4 in the length direction is smaller than the distance between the first hinge point 24 and the center line of the bracket 4 in the length direction, and the distance between the second hinge point 25 and the end face of the other end of the bracket 4 in the length direction is smaller than the distance between the second hinge point 25 and the center line of the bracket 4 in the length direction.

[0102] The length direction of the bracket 4 is the same as the width direction of the tail. Since the bracket 4 of the tail linkage mechanism 100 extends along the width direction of the tail, the first hinge point 24 and the second hinge point 25 are respectively set at both ends of the length direction of the bracket 4, so that the A link 23 and the B link 21 can provide support at both ends of the length direction of the bracket 4, that is, provide support at both ends of the width direction of the tail. In this way, even when the width of the tail is large, it is also helpful to ensure the stability of the tail support. In addition, the use of the two links, the A link 23 and the B link 21, can achieve stable support for the tail, simplifying the structure of the tail linkage mechanism 100 and reducing the manufacturing cost.

[0103] Alternatively, if Figure 1 and Figure 7 As shown, the tail link mechanism 100 further includes a D link 26, that is, the hinge structure 2 further includes a D link 26, one end of the D link 26 is hinged to the base 1, and the other end of the D link 26 is hinged to the B link 21 at a third hinge point 27. The C link 22 and the B link 21 are hinged at a fourth hinge point 28, and the third hinge point 27 is located between the second hinge point 25 and the fourth hinge point 28. When the tail wing linkage mechanism 100 is in a lifted state, the A link 23 and the B link 21 are respectively hinged at the two ends of the bracket 4 along the length direction, the B link 21 extends obliquely upward along the length direction of the bracket 4 and is connected to the bracket 4, and the D link 26 and the B link 21 are hinged at the third hinge point 27, and the third hinge point 27 is located between the second hinge point 25 and the fourth hinge point 28, so that when the B link 21 supports one end of the bracket 4, the D link 26 can also support the B link 21, making up for the problem of insufficient supporting force caused by the longer length of the B link 21, avoiding the shaking of the tail wing linkage mechanism 100, and further improving the reliability of the tail wing support.

[0104] In order to improve the compatibility of the tail link mechanism 100, optionally, in one embodiment of the present disclosure, a plurality of hinge positions are preset on the B link 21, and the D link 26 is matched with one of the plurality of hinge positions. Since the widths of different tails are different, the positions of the center of gravity of the tails are also different. A plurality of hinge positions are set on the B link 21, so that the hinge position between the D link 26 and the B link 21 can be adjusted for the different center of gravity positions of tails of different widths, so that the hinge position between the D link 26 and the B link 21 is always close to the center of gravity of the tail, thereby providing stable support for tails of different specifications.

[0105] In another embodiment provided by the present disclosure, the tail linkage mechanism 100 may include a plurality of B-links 21 of different lengths and a plurality of brackets 4 of different lengths. One of the plurality of brackets 4 is used selectively, and one of the plurality of B-links 21 is used selectively, and each B-link 21 is used in conjunction with the corresponding bracket 4. For tails of different widths, by replacing the bracket 4 adapted to the width of the tail, more effective support can be provided to the tail, so as to avoid the problem of insufficient supporting force caused by the bracket 4 being too short. Moreover, the corresponding B-link can be selected according to the length of the bracket 4, and the center of gravity of the tail can be made closer to the support center of the bracket 4, thereby enhancing the supporting force and supporting effect of the tail linkage mechanism 100 for the tail.

[0106] Alternatively, see Figure 7 and Fig.15 As shown, the B-link 21 may include a third segment 211 and a fourth segment 212 connected to each other. The third segment 211 is the portion of the B-link 21 located between the fourth hinge point 28 and the third hinge point 27. The fourth segment 212 is the portion of the B-link 21 located between the third hinge point 27 and the second hinge point 25. The third segment 211 and the fourth segment 212 are connected at an angle in the height direction of the tail wing linkage mechanism 100, and the height direction is the direction in which the base 1 and the bracket 4 are arranged at intervals.

[0107] The B-link 21 of different lengths may include a third rod segment 211 of fixed length, a plurality of fourth rod segments 212 of different lengths, and a plurality of brackets 4 of different lengths. One of the plurality of brackets 4 is used selectively, and one of the plurality of fourth rod segments 212 is used selectively, and each fourth rod segment 212 is used in conjunction with the corresponding bracket 4. For tail wings of different widths, by replacing the bracket 4 adapted to the width of the tail wing, more comprehensive support can be provided to the tail wing to avoid the problem of insufficient support force caused by too short a bracket 4. In addition, by adjusting the length of the fourth rod segment 212 according to the length of the bracket 4, the center of gravity of the tail wing can be closer to the support center of the bracket 4, thereby improving the support force and support effect of the tail wing linkage mechanism 100 for the tail wing.

[0108] In order to further improve the integrity of the tail linkage mechanism 100, optionally, as Figure 7 and Fig.15As shown, the B link 21 is provided with an arc-shaped protrusion, which protrudes toward the D link 26 along the thickness direction of the base 1, and the protrusion is located at the position where the third rod segment 211 is connected to the fourth rod segment 212. One end of the D link 26 is hinged to the B link 21, and the other end of the D link 26 is hinged to the base 1. In order to ensure the supporting effect of the D link 26, the hinge point between the D link 26 and the base 1 is located in the middle of the bracket 4 along the width direction. The setting of the protrusion allows the B link 21 to be close to the D link 26 located in the middle, so that it is directly connected to the D link 26 through the protrusion, reducing the setting of the connection structure, so that the integrity of the connection between the D link 26 and the B link 21 is stronger, the force transmission path is more direct, and the shaking caused by too many connection points is reduced.

[0109] Furthermore, reducing the connection structure can also reduce the space occupied by the connection structure, further reducing the space occupied by the tail wing linkage mechanism 100.

[0110] In order to improve the stability of the tail link mechanism 100, optionally, as Figure 4 and Figure 7 As shown, the A link 23 is hinged to the base 1 at the fifth hinge point 9, the C link 22 is hinged to the base 1 at the sixth hinge point 10, and the D link 26 is hinged to the base 1 at the seventh hinge point 14. The fifth hinge point 9, the sixth hinge point 10 and the seventh hinge point 14 are respectively located at the three vertices of the same triangle. The bracket 4 is directly or indirectly connected to the base 1 through the A link 23, the B link 21, the C link 22 and the D link 26. The fifth hinge point 9, the sixth hinge point 10 and the seventh hinge point 14 where the link is hinged to the base 1 are respectively set at the three vertices of the same triangle, so that the three links can support each other. Therefore, when the tail link mechanism 100 is in the lifting state, the three links will not easily change the supporting state when subjected to force, and always maintain the supporting effect on the tail.

[0111] In order to reduce abnormal noise during the operation of the tail link mechanism 100, optionally, as Figure 8 and Fig. 9As shown, the tail link mechanism 100 also includes a first buffer 5, which is arranged on the bracket 4. Among them, the bracket 4 is suitable for contacting the tail through the first buffer 5 in any one or more of the lifting state, the stowed state, and the process of switching between the lifting state and the stowed state. That is, the bracket 4 can contact the tail through the first buffer 5 in the lifting state, the bracket 4 can contact the tail through the first buffer 5 in the stowed state, the bracket 4 can contact the tail through the first buffer 5 in both the lifting state and the stowed state, and the bracket 4 can also contact the tail through the first buffer 5 in the process of switching between the lifting state and the stowed state. With such a design, the first buffer 5 arranged on the bracket 4 can contact the tail, thereby avoiding the tail directly contacting the bracket 4 and thus colliding, generating abnormal noise, reducing the probability of collision between the tail and the bracket 4 during the use of the tail link mechanism 100, and improving the user's riding experience.

[0112] To further improve the buffering effect, optionally, Figure 8 and Fig. 9 As shown, the number of the first buffer members 5 is at least two, and the two first buffer members 5 are arranged at intervals along the length direction of the bracket 4. Since the bracket 4 extends along the width direction of the tail wing, the two first buffer members 5 are arranged at intervals along the length direction of the bracket 4, which can increase the contact area between the first buffer member 5 and the tail wing, so that different positions of the tail wing can contact with the first buffer member 5, further reducing the probability of collision between the tail wing and the bracket 4, and reducing the number of abnormal noises.

[0113] Alternatively, if Figure 8 and Fig. 9 As shown, two first buffer members 5 are arranged at both ends of the length direction of the bracket 4. The bracket 4 is used to support the tail wing. The length direction of the bracket 4 coincides with the width direction of the tail wing. A first buffer member 5 is arranged at both ends of the length direction of the bracket 4, respectively, to provide support for the tail wing at both ends of the bracket 4, thereby further increasing the contact area between the tail wing and the first buffer member 5 and reducing the probability of abnormal noise.

[0114] The present disclosure does not limit the connection method between the bracket 4 and the first buffer member 5. In an embodiment provided in the present disclosure, Fig.10 and Fig.11 As shown, one of the bracket 4 and the first buffer 5 is provided with an insertion protrusion 41, and the other of the bracket 4 and the first buffer 5 is provided with an insertion groove 53, and the insertion protrusion 41 is plugged into the insertion groove 53. The plugging and matching connection mode of the insertion protrusion 41 and the insertion groove 53 can increase the convenience of connecting the first buffer 5 with the bracket 4, and facilitate the disassembly, assembly and replacement of the first buffer 5.

[0115] In another embodiment provided in the present disclosure, the first buffer component 5 can be integrally formed with the bracket 4 , thereby improving the durability of the first buffer component 5 .

[0116] The present disclosure does not limit the material of the first buffer member 5 , and for example, the first buffer member 5 may include one or more of rubber, resin or foam plastic.

[0117] In order to reduce the abnormal noise inside the tail link mechanism 100, optionally, as Fig.10 As shown, the first buffer 5 at least includes a first portion 51 and a second portion 52, the first portion 51 protrudes from the first surface of the bracket 4 and is suitable for facing the tail, and the second portion 52 protrudes from the second surface of the bracket 4 and is suitable for facing away from the tail. The tail link mechanism 100 may also include a hinge structure 2, the bracket 4 is mounted on the hinge structure 2, when the tail link mechanism 100 is in the stowed state, the side of the bracket 4 facing away from the tail can be in contact with the hinge structure 2, and when the tail link mechanism 100 is in the lifted state, the side of the bracket 4 facing away from the tail can be separated from the hinge structure 2. The first portion 51 of the first buffer 5 is set to protrude from the first surface of the bracket 4 facing the tail, and the second portion 52 of the first buffer 5 is set to protrude from the second surface of the bracket 4 facing away from the tail, so that when the tail link mechanism 100 is in the stowed state, the second portion 52 can contact with the hinge structure 2, which is conducive to achieving buffering between the bracket 4 and other parts of the tail link mechanism 100 (such as the D link 26 of the hinge structure 2 described below). The first portion 51 may be in contact with the tail wing. When the tail wing linkage mechanism 100 is in the lifted state, the first portion 51 may also be in contact with the tail wing, thereby further eliminating abnormal noises of the tail wing linkage mechanism 100 in different states and improving the riding experience of the user.

[0118] Alternatively, if Fig. 9 As shown, the tail wing linkage mechanism 100 may also include a D-link 26, that is, the hinged structure 2 also includes a D-link 26, one end of the D-link 26 is hinged to the base 1, and the other end of the D-link 26 is hinged to the B-link 21 at a third hinge point 27, and the bracket 4 is suitable for contacting the D-link 26 through the second part 52 during the folding process.

[0119] When the tail wing linkage mechanism 100 is in the lifted state, the D-link 26 can connect the base 1 and the bracket 4 and provide support for the bracket 4; when the D-link 26 is in the retracted state, it can fit with the second surface of the bracket 4 away from the tail wing; the second portion 52 of the first buffer member 5 is set to contact with the D-link 26, so that when the tail wing linkage mechanism 100 is in the retracted state, the D-link 26 will not directly collide with the second surface of the bracket 4, thereby reducing abnormal noise caused by impact.

[0120] In order to further reduce abnormal noise during use, optionally, Figure 4 and Figure 6As shown, in the embodiment where the hinge structure 2 includes an A link 23, one end of the A link 23 is hinged to the bracket 4, and the other end of the A link 23 is hinged to the base 1, the tail link mechanism 100 also includes a second buffer 7, which is arranged on the base 1 or the A link 23. When the A link 23 is in the retracted state, it is suitable to contact the base 1 through the second buffer 7. When the A link 23 is in the retracted state, it is accommodated in the accommodation space formed between the bracket 4 and the base 1. When the A link 23 is in the lifting state, it can rotate around the hinge point between the A link 23 and the base 1, so as to lift the bracket 4 to a preset height. When the A link 23 switches from the lifting state to the retracted state, the second buffer 7 prevents the A link 23 from directly contacting the base 1, thereby generating abnormal noise. On the other hand, it can also provide support and limit for the A link 23, thereby improving the stability of the bracket 4.

[0121] Optionally, a through hole may be formed on the bracket 4, and the through hole is used to accommodate part of the A connecting rod 23 in the retracted state.

[0122] In order to further reduce abnormal noise during the use of the tail wing linkage mechanism 100, optionally, as Figure 1 , Figure 4 , Figure 5 , Figure 6 and Fig.12 As shown, the tail link mechanism 100 further includes a third buffer 6, which is disposed on the base 1 or the bracket 4. When the bracket 4 is in the retracted state, it is suitable for contacting the base 1 through the third buffer 6. In the retracted state of the tail link mechanism 100, in order to prevent the bracket 4 from interfering with the base 1, there is a gap between the bracket 4 and the base 1. Since the hinge structure 2 will shake during the movement of raising or retracting, the third buffer 6 is disposed on the base 1 or the bracket 4, and the third buffer 6 is in contact with the base 1 or the bracket 4 during the retracting process of the bracket 4, thereby preventing the base 1 from colliding with the bracket 4 and eliminating abnormal noise during the use of the tail link mechanism 100.

[0123] The present disclosure does not limit the specific arrangement of the first buffer member 5, the second buffer member 7, and the third buffer member 6. In an embodiment provided in the present disclosure, Figure 6 and Fig.12As shown, the base 1 includes a bottom wall 11, a first side wall 12 and a second side wall 13, the first side wall 12 and the second side wall 13 are arranged at intervals along the thickness direction of the base 1, and the bottom wall 11 is connected between the first side wall 12 and the second side wall 13. The first side wall 12, the second side wall 13, the bottom wall 11 and the bracket enclose an installation space for installing the hinge structure 2 of the tail link mechanism 100, and the third buffer 6 is arranged at one end of the first side wall 12 close to the bracket 4. The third buffer 6 protrudes from the surface of the first side wall 12 away from the second side wall 13 along the thickness direction of the base 1. On the one hand, it does not occupy the volume of the installation space to avoid the hinge structure 2, and on the other hand, it can also increase the coverage of the third buffer 6 to reduce the possibility of direct contact between the bracket 4 and the base 1.

[0124] Alternatively, if Figure 4 and Figure 6 As shown, the second buffer 7 can be located in the installation space, and the third buffer 6 is disposed at one end of the first side wall 12 close to the bracket 4. The second buffer 7 is located in the installation space, and when the tail link mechanism 100 is in the lifting state, the A link 23 can be pressed against the second buffer 7, which, on the one hand, prevents the A link 23 from directly contacting the bottom wall 11 to generate abnormal noise, and on the other hand, can provide support for the A link 23 to improve the stability of the bracket 4.

[0125] The third buffer member 6 protrudes from the surface of the first side wall 12 away from the second side wall 13 along the thickness direction of the base 1. On the one hand, it does not occupy the volume of the installation space to avoid the hinge structure 2. On the other hand, it can also increase the coverage area of ​​the third buffer member 6 and reduce the possibility of direct contact between the bracket 4 and the base 1.

[0126] Optionally, the connection parts of the two connected parts in the tail wing linkage mechanism 100 are treated with plastic coating. For example, at the hinge between the A link 23 and the base 1, the connection holes on the base 1 and the connection holes on the A link 23 are treated with plastic coating to reduce abnormal noise caused by mutual collision or friction when the A link 23 rotates relative to the base 1.

[0127] In order to improve the consistency of the tail link mechanism 100, at least one component of the tail link mechanism 100 is optionally an integrated overmolded component. The integrated overmolded component has a strong processing integrity. Compared with assembling after separate processing or overmolding after processing, the position accuracy and rigidity of the components are higher, which is conducive to the mutual cooperation to form a tail link mechanism 100 with better coordination and stronger integrity.

[0128] The present disclosure does not specifically limit the length of each connecting rod. In one embodiment provided by the present disclosure, the ratio between the lengths of the E connecting rod 29, the F connecting rod 30, the first rod segment 231, the second rod segment 232, the third rod segment 211, the D connecting rod 26 and the C connecting rod 22 can be any appropriate ratio. The length of each connecting rod can be proportionally scaled under the condition of satisfying the ratio range to meet the needs of the support effect of tail wings of different specifications, so that a smaller connecting rod length can be used to meet the support effect of the tail wing, and the requirements for the driving force of the driving mechanism can also be reduced. Under the premise of meeting the support needs of the tail wing, the entire tail wing connecting rod mechanism 100 is smaller in size and lighter in weight.

[0129] Alternatively, if Figure 1 , Figure 4 and Figure 5 As shown, the base 1 includes a bottom wall 11, a first side wall 12 and a second side wall 13; the first side wall 12 and the second side wall 13 are arranged at intervals along the thickness direction of the base 1, and the bottom wall 11 is connected between the first side wall 12 and the second side wall 13; the first side wall 12, the second side wall 13, the bottom wall 11 and the bracket enclose an installation space, and the hinge structure 2 is located in the embodiment of the accommodation space. When the tail link mechanism 100 is in the retracted state, the hinge structure 2 can be accommodated in the installation space, and when the tail link mechanism 100 is in the lifted state, the first side wall 12 and the second side wall 13 can be hinged with the A link 23 and the D link 26 to provide support for the bracket 4. The base 1 is used to connect with the vehicle, so as to fix the tail on the vehicle.

[0130] Alternatively, if Fig.11 As shown, the bracket 4 also includes a first plate 42 and a second plate 43 connected to each other, a connecting portion 44 extending along the height direction of the tail wing linkage mechanism 100 is formed between the first plate 42 and the second plate 43, a first protrusion 45 is formed on the first plate 42 along the height direction of the tail wing linkage mechanism 100, one end of the B link 21 is hinged to the connecting portion 44, and the first protrusion 45 is used to be hinged to the A link 23.

[0131] Alternatively, if Figure 5 and Figure 6 As shown, the upper end of the base 1 has two extension arms 101 which are relatively arranged along the thickness direction of the base 1. The highest point of the extension arm 101 is higher than any point of other parts of the base 1. Each extension arm 101 extends upward at an angle. One end of the D-link 26 is hinged to the upper end of the extension arm 101 through a hinge shaft, and the D-link 26 is located between the two extension arms 101 in the thickness direction of the base 1. The D-link 26 is installed through the two extension arms 101, which is easy to install and can improve the supporting effect of the base 1.

[0132] Specifically, the two extension arms 101 may be respectively disposed on the first side wall 12 and the second side wall 13 of the base 1 .

[0133] As a second aspect provided by the present disclosure, the present disclosure provides a tail assembly, including a tail and the above-mentioned tail linkage mechanism 100 , wherein the tail is mounted on a bracket 4 .

[0134] As a third aspect provided by the present disclosure, the present disclosure provides a vehicle, comprising the above-mentioned tail wing assembly.

[0135] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0136] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0137] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
