Description

Technical Field

[0001] The utility model relates to a car tail wing, in particular to an electric tail wing lifter adjustment mechanism and a car. Background Art

[0002] As people's living standards improve, exterior design becomes one of the primary concerns for most people when buying a car. Electric rear wings have been popularized to ordinary family cars from the original exclusive design of supercars. Since electric rear wings are sports exterior parts, they have higher requirements for internal parts than traditional designs. Due to installation process and space layout limitations, the installation surface size of the electric rear wing panel is usually significantly smaller than its exterior size, resulting in the accumulation of deviations of parts at all levels, where deviations are amplified and there is no deviation compensation, which leads to uneven matching between the electric rear wing and surrounding parts.

[0003] At present, when designing electric rear wing, the main focus is on optimizing the structural design of the electric rear wing lifter to ensure that the unevenness around the electric rear wing can be solved through structural adjustment during vehicle production.

[0032] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] like Figure 1-Figure 5 As shown, an electric tail wing lifter adjustment mechanism in this embodiment includes a mounting bracket 1 and a lifter hinge plate 2, wherein the mounting bracket 1 is connected to the lifter hinge plate 2 via a rotating shaft assembly 3 and an adjustable locking assembly 4; the adjustable locking assembly 4 has a locked state and an unlocked state, and when the adjustable locking assembly 4 is in the locked state, the relative position of the mounting bracket 1 and the lifter hinge plate 2 is fixed; when the adjustable locking assembly 4 is in the unlocked state, the mounting bracket 1 can rotate with the axis of the rotating shaft assembly 3 as the rotation center.

[0034] The mounting bracket 1 is used to be connected to the electric tail wing panel. The electric tail wing lifter drives the lifter hinge plate 2 and the mounting bracket 1 to move, thereby driving the electric tail wing panel to be raised and lowered.

[0035] When manually adjusting the electric tail panel, in case the electric tail panel is "higher at the front and lower at the back" or "lower at the front and higher at the back", the adjustable locking assembly 4 is adjusted to the unlocked state, and then the mounting bracket 1 is rotated to adjust and compensate for the front and rear height differences of the electric tail panel, and finally the adjustable locking assembly 4 is adjusted to the locked state to fix the relative position of the mounting bracket 1 and the lifter hinge plate 2. Since only the adjustable locking assembly 4 needs to be operated, the adjustment operation is simple and the adjustment efficiency is high.

[0036] In this embodiment, the axis of the rotating shaft assembly 3 is in the left-right direction; the axis of the adjustable locking assembly 4 is parallel to the axis of the rotating shaft assembly 3. The axis of the rotating shaft assembly 3 is in the left-right direction, perpendicular to the front-back direction and the up-down direction, and when the rotating shaft assembly 3 is rotated with the axis of the rotating shaft assembly 3 as the rotation center, the front-back height difference of the electric tail panel can be adjusted and compensated. The preferred solution is that the rotating shaft assembly 3 and the adjustable locking assembly 4 are arranged at intervals in the front-back direction.

[0037] In this embodiment, the rotating shaft assembly 3 includes a first bolt 31, a sleeve 32 and a first nut 33. The sleeve 32 is rotatably connected to the lifter hinge plate 2. The bolt rod of the first bolt 31 passes through the sleeve 32 and the mounting bracket 1 and is threadedly connected to the first nut 33.

[0038] The lifter hinge plate 2 and the adjustment longitudinal plate 12 are located between the bolt head of the first bolt 31 and the first nut 33, the adjustment longitudinal plate 12 is fixedly connected to the shaft assembly 3, and the shaft assembly 3 is rotatably connected to the lifter hinge plate 2. Therefore, when the adjustable locking assembly 4 is in an unlocked state, the adjustment longitudinal plate 12 can rotate relative to the lifter hinge plate 2 with the axis of the shaft assembly 3 as the rotation center; and when the adjustable locking assembly 4 is in a locked state, the adjustment longitudinal plate 12, the locking assembly and the lifter hinge are connected and the relative positions are fixed, and the shaft assembly 3 will not rotate.

[0039] In this embodiment, the adjustable locking assembly 4 includes a second bolt 41 and a second nut 42. The second bolt 41 is connected to the lifter hinge plate 2 in a non-coaxial relative rotation manner. The bolt shank of the second bolt 41 passes through the lifter hinge plate 2 and the mounting bracket 1 and is threadedly connected to the second nut 42. The locking hole 22 is a non-circular hole. The bolt shank of the second bolt 41 is conformally matched with the locking hole 22, so the second bolt 41 will not rotate relative to the lifter hinge plate 2. After the second nut 42 is tightened, the lifter hinge plate 2 and the adjustment longitudinal plate 12 are fixed between the bolt head of the second bolt 41 and the second nut 42.

[0040] In this embodiment, the mounting bracket 1 includes a mounting transverse plate 11 and an adjustment longitudinal plate 12 connected to the mounting transverse plate 11, and the adjustment longitudinal plate 12 is provided with a first strip hole 121 and a second strip hole 122, the first strip hole 121 and the second strip hole 122 are both through in the left-right direction, and the length directions of the first strip hole 121 and the second strip hole 122 are both perpendicular to the upper end surface of the mounting transverse plate 11; the lifter hinge plate 2 is provided with a rotating shaft hole 21 and a locking hole 22, the position of the rotating shaft hole 21 corresponds to the first strip hole 121, and the position of the locking hole 22 corresponds to the position of the second strip hole 122.

[0041] The installation horizontal plate 11 and the adjustment vertical plate 12 together form an "L"-shaped installation bracket 1. When the electric tail panel is manually adjusted, if the electric tail panel is too high or too low as a whole, the first strip hole 121 and the second strip hole 122 can adjust the position of the installation bracket 1 in the up and down direction after the first nut 33 and the second nut 42 are loosened, and the first nut 33 and the second nut 42 are tightened after adjustment so that the installation bracket 1 is fixed at the adjusted position.

[0042] In this embodiment, the sleeve 32 includes a rotating main body 321 and a flanged portion 322 connected to the rotating main body 321; the rotating main body 321 is located between the rotating shaft hole 21 and the first bolt 31, and the bolt rod of the first bolt 31 passes through the sleeve 32 and the first strip hole 121 and is threadedly connected to the first nut 33; the flanged portion 322 is located between the lifter hinge plate 2 and the adjustment longitudinal plate 12; the adjustable locking assembly 4 also includes a first gasket 43 with the same thickness as the flanged portion 322, and the first gasket 43 is located between the lifter hinge plate 2 and the adjustment longitudinal plate 12. The rotating main body 321 can rotate relative to the lifter hinge plate 2. When the first nut 33 and the second nut 42 are tightened, the flanged portion 322 and the first gasket 43 are used to fix the distance between the adjustment longitudinal plate 12 and the lifter hinge plate 2, and the flanged portion 322 and the first gasket 43 can serve as a support surface to provide support for the adjustment longitudinal plate 12.

[0043] In this embodiment, the length of the rotating main body 321 is greater than the thickness of the lifter hinge plate 2, so that there is a gap between the bolt head of the first bolt 31 and the lifter hinge plate 2. After the first nut 33 is tightened by rotating the main body 321, the locking force is sequentially transmitted through the third gasket 34, the adjustment longitudinal plate 12, the flange 322 of the sleeve 32, the rotating main body 321 of the sleeve 32, and the bolt head of the first bolt 31, that is, the locking force is transmitted to the bolt head of the first bolt 31 through the sleeve 32 instead of the lifter hinge plate 2, so tightening the first nut 33 will not affect the relative rotational matching relationship between the sleeve 32 and the lifter hinge plate 2.

[0044] In this embodiment, the locking hole 22 is a square hole, and the bolt shank of the second bolt 41 is conformably matched with the locking hole 22; the bolt shank of the second bolt 41 is gap matched with the width direction of the second strip hole 122. The width direction dimension of the second strip hole 122 is slightly larger than the outer diameter of the bolt shank of the second bolt 41. When the mounting bracket 1 rotates with the axis of the rotating shaft assembly 3 as the rotation center, the relative position of the bolt shank of the second bolt 41 and the second strip hole 122 changes. The gap match between the bolt shank of the second bolt 41 and the second strip hole 122 in the width direction can compensate for this change, thereby preventing the mounting bracket 1 from being unable to rotate due to the interference between the second bolt 41 and the second strip hole 122.

[0045] In this embodiment, the shaft assembly 3 also includes a third gasket 34 , which is located between the first nut 33 and the adjustment longitudinal plate 12 ; the adjustable locking assembly 4 also includes a fourth gasket 44 , which is located between the second nut 42 and the adjustment longitudinal plate 12 .

[0046] The following is an overall description of the manual adjustment of the electric tail panel:

[0047] If the electric tail wing panel is too high or too low as a whole, loosen the first nut 33 and the second nut 42, then adjust the mounting bracket 1 to the correct position in the up and down directions, and then tighten the first nut 33 and the second nut 42 to fix the mounting bracket 1 in the adjusted position.

[0048] For the electric tail panel "higher at the front and lower at the back" or "lower at the front and higher at the back", the second nut 42 is loosened to adjust the adjustable locking assembly 4 to the unlocked state, and then the mounting bracket 1 is rotated to adjust and compensate for the front and rear height differences of the electric tail panel. Finally, the second nut 42 is tightened to adjust the adjustable locking assembly 4 to the locked state, so that the relative position of the mounting bracket 1 and the lifter hinge plate 2 is fixed. For the electric tail panel "higher at the front and lower at the back" or "lower at the front and higher at the back", the adjustment process only requires loosening and tightening the second nut 42, which makes the adjustment operation simpler and more efficient.

[0049] A car in this embodiment includes the above-mentioned electric rear wing lifter adjustment mechanism.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
