DETAILED DESCRIPTION

[0044] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0045] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0046] Reference Figures 1 to 3 As shown, this embodiment provides a flushness adjustment device, including a support plate 1 and a rotating disc structure.

[0047] Among them, the support plate 1 is used to support the part to be adjusted 4, the rotating disc structure is located on one side of the support plate 1, a protrusion 31 is provided on the rotating disc structure, a groove 41 is provided on the part to be adjusted 4 at a position corresponding to the protrusion 31, and the protrusion 31 is located in the groove 41.

[0048] The axis of the rotating disk structure and the rotation center of the slot 41 are eccentrically arranged so that when the rotating disk structure rotates, the protrusion 31 slides along the slot 41 to drive the to-be-adjusted member 4 to rise and fall relative to the support plate 1 .

[0049] When implementing it, refer to Figure 1 As shown, the part to be adjusted 4 can be arranged above the fixed plate 5 and can slide vertically relative to the fixed plate 5. The part to be adjusted 4 is provided with a slot 41 extending along the axial direction of the turntable 3, and the rotation center of the slot 41 is eccentric to the axis of the rotating disc structure. Therefore, when the user manually rotates the rotating disc structure, the protrusion 31 slides in the slot 41, thereby driving the part to be adjusted 4 to rise or fall, thereby changing the height position of the part to be adjusted 4, so that the surface difference between it and the part 8 on the right side can be within the design requirements, for example, Figure 1 As shown, at this time, the part 4 to be adjusted can be flush with the part 8 on the right to eliminate the surface difference.

[0050] Reference Figure 1 As shown, in some embodiments, the slot 41 can be set as an arc-shaped slot extending along the circumference of the turntable 3, so that the protrusion 31 can slide along the arc-shaped slot, thereby driving the to-be-adjusted member 4 to move smoothly, so as to achieve the smooth lifting and lowering of the to-be-adjusted member 4. Alternatively, in some other implementations, the slot 41 can also be set as a horizontal slot extending in the horizontal direction, in which case the rotation center of the horizontal slot can be understood to be at infinity.

[0051] In some embodiments, the rotating disc structure includes a rotating shaft assembly 2 and a turntable 3 connected to the rotating shaft assembly 2. The turntable 3 is located on one side of the support plate 1 and the protrusion 31 is arranged on the turntable 3. The axis of the rotating shaft assembly 2 is eccentrically arranged with the rotation center of the slot 41.

[0052] In a specific implementation, the shaft assembly 2 can be rotated manually, so that the shaft assembly 2 drives the turntable 3 to rotate, so that the protrusion 31 slides in the slot 41 to drive the to-be-adjusted member 4 to rise or fall.

[0053] For example, the gear adjustment can be switched by rotating the shaft assembly 2 at different angles. Figure 1 The position of the shaft assembly 2 shown is the initial position. At this time, the shaft assembly 2 can be rotated 30° counterclockwise to Figure 7 and Figure 8 The position shown in FIG. 1 is the position shown in FIG. 1 , at which time the surface difference between the part to be adjusted 4 and the part 8 on the right is adjusted to be greater than Figure 1 The flushness at the position shown.

[0054] When continuing will be in Figure 7 and Figure 8 The rotating shaft assembly 2 at the position shown in the figure rotates 30° counterclockwise to Fig. 9 and Fig.10 When the position is shown, the surface difference between the part to be adjusted 4 and the part 8 on the right is adjusted to be greater than Figure 7 and Figure 8 The flushness shown.

[0055] When continuing will be in Fig. 9 and Fig.10 The rotating shaft assembly 2 at the position shown in the figure rotates 30° counterclockwise to Fig.11 and Fig.12 When the position is shown, the surface difference between the part to be adjusted 4 and the part 8 on the right is adjusted to be greater than Fig. 9 and Fig.10 The flushness shown.

[0056] When continuing will be in Fig.11 and Fig.12 The rotating shaft assembly 2 at the position shown in the figure rotates 30° counterclockwise to Fig.13 and Fig.14 When the position is shown, the surface difference between the part to be adjusted 4 and the part on the right is adjusted to be greater than Fig.11 and Fig.12 Through the above process, the adjustment of the face difference of different gears can be achieved to meet the design requirements.

[0057] Exemplarily, the protrusion 31 on the turntable 3 may be a protruding column, and the protruding column may be integrally formed on the turntable 3 , or may be clipped or fixed to the turntable 3 via a fastener 6 .

[0058] In summary, the face difference adjustment device of the present embodiment can drive the turntable 3 to rotate by rotating the rotating shaft assembly 2. Since the rotation center of the slot 41 is eccentrically arranged with respect to the axis of the rotating shaft assembly 2, when the protrusion 31 of the turntable 3 slides along the slot 41 of the part to be adjusted 4, the part to be adjusted 4 is driven to rise and fall relative to the support plate 1, thereby changing the height of the part to be adjusted 4. In this way, the part to be adjusted 4 can be adjusted to a level within an allowable range with respect to the face difference of other parts, thereby achieving effective adjustment of the face difference to effectively ensure the assembly effect of the whole vehicle.

[0059] Reference Figure 4 and Figure 5 As shown, in some embodiments, the support plate 1 has an avoidance hole 11 for the shaft assembly 2 to pass through, and the shaft assembly 2 is connected to the turntable 3 after passing through the avoidance hole 11, and part of the shaft assembly 2 is located outside the support plate 1.

[0060] In specific implementation, the shaft assembly 2 first passes through the avoidance hole 11 of the support plate 1 and then is connected to the turntable 3, and part of the shaft assembly 2 is located outside the support plate 1, so that it is convenient for the user to rotate the shaft assembly 2 located outside the support plate 1 to drive the turntable 3 to rotate, and then drive the part to be adjusted 4 to rise and fall.

[0061] Reference Figure 6 As shown, in some embodiments, the rotating shaft assembly 2 includes a rotating handle 21 and a rotating shaft 22 connected to the rotating handle 21, the rotating handle 21 is located outside the support plate 1, the rotating shaft 22 passes through the avoidance hole 11 and is connected to the turntable 3, and the axis of the rotating shaft 22 is eccentrically arranged with respect to the center of the turntable 3.

[0062] In a specific implementation, the rotating handle 21 can be rotated to drive the rotating shaft 22 to rotate, and when the rotating shaft 22 rotates, the turntable 3 is driven to rotate. Since the axis of the rotating shaft 22 is eccentrically arranged with the center of the turntable 3, when the turntable 3 rotates, the protrusion of the turntable 3 slides along the groove 41 of the part to be adjusted 4, thereby driving the part to be adjusted 4 to rise and fall, so as to adjust the surface difference between it and the adjacent part 8, so as to adjust the surface difference within the allowable range.

[0063] Exemplarily, the rotating handle 21 and the rotating shaft 22 can be integrally formed to save manufacturing steps and improve the overall structural strength of the rotating shaft assembly 2; or the rotating handle 21 and the rotating shaft 22 can be formed separately and then snap-fitted or welded together.

[0064] Reference Figures 4 to 6As shown, in some embodiments, a non-rotating hole 32 is provided on the turntable 3, and the rotating shaft 22 is inserted into the non-rotating hole 32 and can move axially relative to the turntable 3; the outer contour shape of at least a portion of the rotating shaft 22 located in the non-rotating hole 32 is adapted to the non-rotating hole 32 to limit the rotation of the rotating shaft 22 relative to the turntable 3.

[0065] That is, by providing the non-rotating hole 32 to match the outer contour of the portion of the rotating shaft 22 located in the non-rotating hole 32, the rotating shaft 22 can be relatively fixed in the circumferential direction after being inserted in the non-rotating hole 32 of the rotating disk 3, that is, the rotating shaft 22 can drive the rotating disk 3 to rotate synchronously when rotating. That is, the rotating shaft 22 can move along the axial direction of the non-rotating hole 32, but cannot rotate relative to the rotating disk 3 along the circumferential direction of the non-rotating hole 32.

[0066] For example, the non-rotating hole 32 may be a hexagonal hole, and the cross section of the portion of the rotating shaft 22 inserted into the non-rotating hole 32 may be a hexagonal hole. Alternatively, the non-rotating hole 32 may be an octagonal hole, and the cross section of the portion of the rotating shaft 22 inserted into the non-rotating hole 32 may be an octagonal hole. The specific shape of the non-rotating hole 32 can be set according to actual needs, and this embodiment does not specifically limit this.

[0067] Reference Figure 4 and Figure 5 As shown, in some embodiments, the face difference adjustment device also includes a fixed plate 5, which is located on the side of the turntable 3 away from the support plate 1 and is fixedly connected to the support plate 1; a locking portion is provided on the fixed plate 5 at a position corresponding to the rotating shaft 22, and the locking portion is used to cooperate with the rotating shaft 22 to limit the rotation of the rotating shaft 22.

[0068] In a specific implementation, the support plate 1, the rotating disk 3 and the fixed plate 5 are sequentially arranged along the axial direction of the rotating shaft 22, and the support plate 1 and the fixed plate 5 are fixed together. A locking portion is arranged on the fixed plate 5, and when the rotation of the rotating shaft 22 is not required, the rotating shaft 22 can be locked by the locking portion, thereby limiting the rotation of the rotating shaft 22, thereby limiting the rotation of the rotating disk 3, and fixing the to-be-adjusted member 4 at the preset position after adjustment.

[0069] Reference Figures 4 to 6 As shown, in some embodiments, the locking portion includes a non-rotating locking hole 51, and the outer contour shape of the end of the rotating shaft 22 close to the fixed plate 5 is adapted to the non-rotating locking hole 51; the rotating shaft 22 can move toward the direction close to the fixed plate 5 and be inserted into the non-rotating locking hole 51 to limit the rotation of the rotating shaft 22, or the rotating shaft 22 can move toward the direction away from the fixed plate 5 to move out of the non-rotating locking hole 51.

[0070] In specific implementation, when the rotating shaft 22 needs to be locked to limit its rotation, the rotating shaft 22 can be moved toward the direction of the fixed plate 5 and inserted into the non-rotating locking hole 51 of the fixed plate 5. At this time, the rotating shaft 22 cannot rotate. Figure 4 shown.

[0071] When it is necessary to unlock the rotating shaft 22 so that the rotating shaft 22 can continue to rotate to drive the turntable 3 to rotate, the rotating shaft 22 can be moved in a direction away from the fixed plate 5 and out of the non-rotating locking hole 51. At this time, the rotating shaft 22 can continue to rotate. Figure 5 shown.

[0072] For example, the non-rotating locking hole 51 may be a dodecagonal hole, and the cross section of the portion of the rotating shaft 22 inserted into the non-rotating locking hole 51 may be a dodecagonal hole. Alternatively, the non-rotating locking hole 51 may be a tetradecagonal hole, and the cross section of the portion of the rotating shaft 22 inserted into the non-rotating locking hole 51 may be a tetradecagonal hole. The specific shape of the non-rotating locking hole 51 can be set according to actual needs, and this embodiment does not specifically limit this.

[0073] Reference Figure 4 and Figure 5 As shown, in some embodiments, a first connecting hole is provided on the support plate 1, and a second connecting hole is provided on the fixing plate 5, and the support plate 1 and the fixing plate 5 are connected by a fastener 6 which is penetrated through the first connecting hole and the second connecting hole; and a sliding groove 33 for sliding the fastener 6 is provided at a position corresponding to the first connecting hole on the turntable 3, and the sliding groove 33 extends along the circumference of the turntable 3.

[0074] That is to say, when the support plate 1 and the fixed plate 5 are connected by the fastener 6 inserted into the first connecting hole and the second connecting hole, the support plate 1 and the fixed plate 5 are both fixed, and since the turntable 3 is located between the support plate 1 and the fixed plate 5, a sliding groove 33 extending along the circumferential direction for the fastener 6 to slide can be provided on the turntable 3, so that the fastener 6 can slide in the sliding groove 33 when the turntable 3 rotates, so as to avoid interfering with or affecting the rotation of the turntable 3.

[0075] For example, the first connection hole and the second connection hole may be threaded holes, and the fastener 6 may be a bolt. Alternatively, the first connection hole and the second connection hole may be plain holes, and the fastener 6 may be a fastening pin.

[0076] In addition, a plurality of first connection holes can be provided, and the plurality of first connection holes are arranged at circumferential intervals along the support plate 1, and a plurality of second connection holes are also provided and correspond one-to-one to the first connection holes, so that the connection reliability between the support plate 1 and the fixing plate 5 can be improved through the cooperation of the plurality of first connection holes and the second connection holes.

[0077] Reference Figure 2 , Figure 3 As shown, in some embodiments, an elastic locking structure 23 is provided on the rotating shaft assembly 2, and at least two stop grooves 12 are provided at positions on the support plate 1 corresponding to the elastic locking structure 23, and at least two stop grooves 12 are arranged at intervals along the circumference of the support plate 1, and the elastic locking structure 23 can be inserted into the corresponding stop grooves 12.

[0078] That is to say, when the shaft 22 is rotating, after the shaft 22 rotates to a certain angle, the elastic locking structure 23 is snapped into the stop groove 12. At this time, the shaft 22 can be temporarily fixed at this position, so as to finally temporarily fix the part 4 to be adjusted at the adjustment position.

[0079] For example, refer to Figures 7 to 14 As shown, the shaft assembly 2 in this embodiment can be switched between four different gears, and at this time, four stop slots 12 can be set, for example, the angle between the four stop slots 12 can be 30°, so that after the shaft 22 rotates 30°, the elastic locking structure 23 can be inserted into the corresponding stop slot 12. Of course, in other implementations, the shaft assembly 2 can be set to have other numbers of gears, and at this time, the number of stop slots 12 can be set according to the actual number of gears.

[0080] Exemplarily, the elastic locking structure 23 may specifically include a spring and a clamping column connected to one end of the spring. When the spring is compressed, the clamping column can move in a direction away from the stop groove 12 until it moves out of the stop groove 12, so that the rotating shaft 22 can rotate, or it can move in a direction close to the stop groove 12 and be inserted into the stop groove 12 under the action of the elastic restoring force of the spring, so that the rotating shaft 22 is temporarily non-rotatable.

[0081] Reference Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, a support column 13 extending vertically is provided on the support plate 1, and a sliding hole is provided on the part to be adjusted 4 at a position corresponding to the support column 13, and the support column 13 extends into the sliding hole, so that the part to be adjusted 4 can be raised and lowered relative to the support part.

[0082] Exemplarily, two support columns 13 can be provided, and the two support columns 13 can be spaced apart along the length direction of the part to be adjusted 4. Two sliding holes are also provided and correspond one to one with the support columns 13, so that the lifting and lowering of the part to be adjusted 4 can be smoother.

[0083] Reference Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, an elastic member 7 is sleeved on the outer wall of the support column 13, and the elastic member 7 is located outside the sliding hole, so that it can buffer the rise and fall of the adjustable member 4 when the adjustable member 4 descends or rises, thereby ensuring the smooth rise and fall of the adjustable member 4.
