Description

Technical Field

[0001] The present disclosure relates to the technical field of vehicle tail wings, and in particular to a tail wing linkage mechanism, a tail wing assembly and a vehicle. Background Art

[0002] Installing a spoiler at the rear of a vehicle can, on the one hand, guide the flow direction of the airflow at the rear of the vehicle so that the vehicle is subject to less resistance; on the other hand, it can increase the vehicle's grip during driving. The spoiler is connected to the vehicle through a connecting rod mechanism, which can control the rise and fall of the spoiler, thereby raising or lowering the spoiler in different vehicle usage scenarios.

[0003] During the driving process of the vehicle, on the one hand, since the rear wing itself has a certain weight, it needs to be supported by a connecting rod mechanism. On the other hand, the rear wing will also shake due to the influence of airflow. In the related technology, the connecting rod mechanism has insufficient supporting force for the rear wing and poor supporting stability, which can easily cause the rear wing to shake during use, affecting the normal operation of the rear wing, increasing driving wind resistance, and even causing the rear wing to fall off the vehicle.

DETAILED DESCRIPTION

[0051] 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.

[0052] In the present disclosure, unless otherwise specified, directional words such as "upper" and "lower" are generally defined based on the drawing direction of the corresponding drawings. "Inner" and "outer" refer to the inner and outer sides of the contour of the corresponding component. In addition, the terms "first", "second", etc. are only used to distinguish descriptions and cannot be understood as indicating or implying relative importance.

[0053] As one aspect of the present disclosure, Figures 1 to 7 As shown, the present disclosure provides a tail link mechanism 100, including a base 1, a first hinge structure 2, a second hinge structure 3 and a bracket 4, wherein the bracket 4 is used to install the tail. The first hinge structure 2 is arranged between the base 1 and the bracket 4, and the second hinge structure 3 is arranged between the base 1 and the bracket 4. The first hinge structure 2 and the bracket 4 are hinged at a first hinge point 5, and the second hinge structure 3 and the bracket 4 are hinged at a second hinge point 6. The first hinge point 5 and the second hinge point 6 are respectively located at two ends of the length direction of the bracket 4.

[0054] The length direction of the bracket 4 is the same as the width direction of the tail wing. Since the bracket 4 of the tail wing linkage mechanism 100 extends along the width direction of the tail wing, through the above technical scheme, the first hinge point 5 and the second hinge point 6 are respectively set at both ends of the length direction of the bracket 4, so that the first hinge structure 2 and the second hinge structure 3 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 wing. In this way, even if the width of the tail wing is large, it is beneficial to ensure the stability of the support of the tail wing, thereby helping to avoid the situation where the normal operation of the tail wing is affected by shaking during use, or even the tail wing falls off the vehicle.

[0055] It can be understood that, here, the first hinge point 5 and the second hinge point 6 are respectively located at the two ends of the length direction of the bracket 4, which can refer to the first hinge point 5 and the second hinge point 6 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 5 and the end face of one end of the length direction of the bracket 4 is smaller than the distance between the first hinge point 5 and the center line of the length direction of the bracket 4, and the distance between the second hinge point 6 and the end face of the other end of the length direction of the bracket 4 is smaller than the distance between the second hinge point 6 and the center line of the length direction of the bracket 4.

[0056] Alternatively, if Figure 1As shown, the first hinge structure 2 includes at least an A link 21, and the second hinge structure 3 includes at least a B link 31. The A link 21 is hinged to the bracket 4 at a first hinge point 5, and the B link 31 is hinged to the bracket 4 at a second hinge point 6. The A link 21 and the B link 31 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 wing. The two links of the A link 21 and the B link 31 can be used to achieve stable support for the tail wing, simplifying the structure of the tail wing linkage mechanism 100 and reducing the manufacturing cost.

[0057] Alternatively, if Figure 1 As shown, the second hinge structure 3 also includes a C-link 32, one end of the C-link 32 is hinged to the B-link 31, and the other end of the C-link 32 is hinged to the base 1. The tail link mechanism 100 can include a lifting state and a stowed state. In the lifting state, the tail link mechanism 100 can lift the tail. The B-link 31 is connected to the base 1 through the C-link 32. When the lifting height is the same, the length of the C-link 32 and the B-link 31 can be reduced. At the same time, the B-link 31 and the C-link 32 can be bent at the hinge point, thereby reducing the size of the tail link mechanism 100 in the stowed state along the height direction and the length direction of the bracket 4, further reducing the occupied space of the tail link mechanism 100.

[0058] The present disclosure does not limit the hinge mode between the B link 31 and the C link 32. In one embodiment of the present disclosure, the B link 31 has a first end 311 and a second end 312 opposite to each other, one end of the C link 32 is hinged to the first end 311 of the B link 31, and the second end 312 of the B link 31 is hinged to the bracket 4. The two ends of the B link 31 are respectively connected to the bracket 4 and the C link 32, which can increase the height of the tail when the tail link mechanism 100 is in the lifting state, and at the same time, can increase the range of motion of the B link 31.

[0059] In order to improve the supporting effect of the tail wing linkage mechanism 100, optionally, as Figure 1As shown, the second hinge structure 3 also includes a D link 33, one end of the D link 33 is hinged to the base 1, and the other end of the D link 33 is hinged to the B link 31 at the third hinge point 7. The C link 32 and the B link 31 are hinged to the fourth hinge point 8, and the third hinge point 7 is located between the second hinge point 6 and the fourth hinge point 8. When the tail wing linkage mechanism 100 is in a lifted state, the A link 21 and the B link 31 are respectively hinged at the two ends of the bracket 4 along the length direction, the B link 31 extends obliquely upward along the length direction of the bracket 4 and is connected to the bracket 4, and the D link 33 and the B link 31 are hinged at the third hinge point 7, and the third hinge point 7 is located between the second hinge point 6 and the fourth hinge point 8, so that when the B link 31 supports one end of the bracket 4, the D link 33 can also support the B link 31, making up for the problem of insufficient supporting force caused by the longer length of the B link 31, avoiding the shaking of the tail wing linkage mechanism 100, and further improving the reliability of the tail wing support.

[0060] Alternatively, if Figure 2 , Figure 3 and Figure 6 As shown, the B-link 31 includes a first rod segment 313 and a second rod segment 314 connected to each other. The first rod segment 313 is the portion of the B-link 31 located between the fourth hinge point 8 and the third hinge point 7, and the second rod segment 314 is the portion of the B-link 31 located between the third hinge point 7 and the second hinge point 6. The first rod segment 313 and the second rod segment 314 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. When the tail linkage mechanism 100 is in a folded state, the B link 31 can be accommodated in the accommodating space between the bracket 4 and the base 1, and the B link 31 is divided into a first rod segment 313 and a second rod segment 314, and the first rod segment 313 and the second rod segment 314 are connected at an angle in the height direction of the tail linkage mechanism 100, that is, the B link 31 is not a straight rod in the height direction of the tail linkage mechanism 100, and at least includes a first rod segment 313 and a second rod segment 314 connected at an angle. Such a design can make the first rod segment 313 as close to the bracket 4 as possible, thereby making full use of the space between the bracket 4 and the base 1, and at the same time, it can also make the overall structure of the tail linkage mechanism 100 more compact, which is conducive to making the space occupied by the tail linkage mechanism 100 smaller.

[0061] In order to adapt to tail wings of different specifications, the B link 31 is optionally provided with a plurality of hinge positions, and the D link 33 is matched with one of the plurality of hinge positions. Since the widths of different tail wings are different, the positions of the center of gravity of the tail wings are also different. The B link 31 is provided with a plurality of hinge positions, so that the hinge position between the D link 33 and the B link 31 can be adjusted for the different center of gravity positions of tail wings of different widths, so that the hinge position between the D link 33 and the B link 31 is always close to the center of gravity of the tail wing, thereby providing stable support for tail wings of different specifications.

[0062] In another embodiment provided by the present disclosure, the tail link mechanism 100 may include a plurality of second rod segments 314 of different lengths and a plurality of brackets 4 of different lengths, and the plurality of brackets 4 may be used one by one, and the plurality of second rod segments 314 may be used one by one, and each second rod segment 314 may be 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 comprehensive support may be provided to the tail, so as to avoid the problem of insufficient support force caused by the bracket 4 being too short. Moreover, by adjusting the length of the second rod segment 314 according to the length of the bracket 4, the center of gravity of the tail may be closer to the support center of the bracket 4, thereby improving the support force and support effect of the tail link mechanism 100 for the tail.

[0063] In order to further improve the integrity of the tail linkage mechanism 100, optionally, as Figure 2 and Figure 3 As shown, the B link 31 is provided with a protrusion 315, which protrudes toward the D link 33 along the thickness direction of the base 1, and the protrusion 315 is located at the position where the first rod segment 313 is connected to the second rod segment 314. One end of the D link 33 is hinged to the B link 31, and the other end of the D link 33 is hinged to the base 1. In order to ensure the supporting effect of the D link 33, the hinge point between the D link 33 and the base 1 is located in the middle of the bracket 4 along the width direction. The setting of the protrusion 315 allows the B link 31 to be close to the D link 33 located in the middle, so that it is directly connected to the D link 33 through the protrusion 315, reducing the setting of the connection structure, so that the integrity of the connection between the D link 33 and the B link 31 is stronger, the force transmission path is more direct, and the shaking caused by too many connection points is reduced.

[0064] 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.

[0065] In order to improve the stability of the tail link mechanism 100, optionally, as Figure 2 and Figure 4As shown, the A link 21 is hinged to the base 1 at the fifth hinge point 9, the C link 32 is hinged to the base 1 at the sixth hinge point 10, and the D link 33 is hinged to the base 1 at the seventh hinge point 11. The fifth hinge point 9, the sixth hinge point 10 and the seventh hinge point 11 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 21, the B link 31, the C link 32 and the D link 33. The fifth hinge point 9, the sixth hinge point 10 and the seventh hinge point 11 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.

[0066] Alternatively, if Figure 4 and Figure 5 As shown, the first hinge structure 2 further includes an E link 22 and an F link 23, one end of the E link 22 is hinged to the base 1, the other end of the E link 22 is hinged to one end of the F link 23, the other end of the F link 23 is hinged to the A link 21, the E link 22 is suitable for transmission connection with the driving mechanism, and the E link 22 can be constructed as a crank of the first hinge structure 2. The tail link mechanism 100 can be switched between the lifting state and the stowed state under the drive of the driving mechanism, the E link 22 is connected to the transmission shaft 12 of the driving mechanism, and is constructed as a crank, so that the E link 22 can drive the F link 23 to do a planar composite motion of both swinging and moving when rotating, thereby driving the A link 21 to rise or fall, so that the bracket 4 is lifted or stowed.

[0067] like Figure 5 and Figure 6 As shown, the A link 21 may include a third rod segment 211 and a fourth rod segment 212, the third rod segment 211 and the fourth rod segment 212 are connected at an angle in the height direction of the tail link mechanism 100, the end of the third rod segment 211 away from the fourth rod segment 212 is hinged to the base 1, and the end of the fourth rod segment 212 away from the third rod segment 211 is hinged to the bracket 4. That is, the A link 21 is not a straight rod in the height direction of the tail link mechanism 100, and at least includes the third rod segment 211 and the fourth rod segment 212 connected at an angle. The third rod segment 211 and the fourth rod segment 212 of the A link 21 are arranged to be connected at an angle, so that the A link 21 is constructed 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 21 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.

[0068] like Figure 5As shown, optionally, the end of the third rod segment 211 away from the fourth rod segment 212 is the first end of the A link 21, that is, the first end of the A link 21 is hinged to the base 1, and the end of the fourth rod segment 212 away from the third rod segment 211 is the second end of the A link 21, that is, the second end of the A link 21 is hinged to the bracket 4. The third rod segment 211 and the fourth rod segment 212 are connected at point Q, and the F link 23 is connected to the driving mechanism at point T (as shown in FIG. Figure 5 In other words, by making the Q point and the T point located on both sides of the line connecting the first end and the second end, the A connecting rod 21 can be bent toward the F connecting rod 23 and the driving mechanism, and the projections of the F connecting rod 23 and the A connecting rod 21 on the base 1 are along the length direction of the base 1 (as shown in FIG. Figure 5 The A connecting rod 21 extends in the left-right direction of the drawing, that is, the bent opening of the A connecting rod 21 faces the F connecting rod 23, so that the F connecting rod 23 can be at least partially accommodated in the bent opening of the A connecting rod 21. In this way, it is helpful to reduce the size of the whole structure of the A connecting rod 21 and the F connecting rod 23 in the length direction of the base 1, thereby reducing the space occupied.

[0069] It is understandable that the T point can be located on the F connecting rod 23 itself, or on an intermediate component connecting the F connecting rod 23 and the driving mechanism, such as the E connecting rod 22 connecting the F connecting rod 23 and the transmission shaft 12 of the driving mechanism.

[0070] Alternatively, if Figure 5 and Figure 6 As shown, the F link 23 is hinged at the connection position of the third rod segment 211 and the fourth rod segment 212. During the transformation of the tail link mechanism 100 from the stowed state to the lifted state, since the F link 23 is hinged at the connection position of the third rod segment 211 and the fourth rod segment 212, the F link 23 can be driven by the driving mechanism to push the third rod segment 211 and the fourth rod segment 212 to rotate around the base 1 and the bracket 4 respectively, thereby driving the bracket 4 to rise, and the A link 21 rotates to the supporting position. At the same time, through reasonable design, in the case of Figure 6 In the embodiment of the present invention, the E link 22 and the F link 23 are collinear to form a self-locking structure. At this time, under the push-up action of the F link 23, the A link 21 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 22 and the F link 23, ensuring the stability of the support of the tail link mechanism 100.

[0071] The present disclosure does not specifically limit the length of each connecting rod. In an embodiment provided in the present disclosure, Figure 6As shown, the ratios among the lengths of the E link 22, the F link 23, the third rod segment 211, the fourth rod segment 212, the first rod segment 313, the D link 33 and the C link 32 can be any appropriate ratios. The lengths of the various links can be scaled proportionally under the condition of satisfying the ratio range to meet the needs of the supporting effect of the tail wing of different specifications, so that a smaller link length can be used to meet the supporting effect of the tail wing, and the requirements for the driving force of the driving mechanism can also be reduced. On the premise of meeting the support requirements for the tail wing, the entire tail wing linkage mechanism 100 is smaller in size and lighter in weight.

[0072] Alternatively, if Figure 7 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.

[0073] 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 .

[0074] As a third aspect provided by the present disclosure, the present disclosure provides a vehicle, comprising the above-mentioned tail wing assembly.

[0075] 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.
