Detailed Implementation

[0029] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figures 1-14 Description of the adjustment mechanism 100 according to an embodiment of the present utility model.

[0030] The adjusting mechanism 100 according to a first aspect embodiment of the present invention is characterized in that it comprises: Fixing part 1, the fixing part 1 is provided with mounting groove 11; and, Movement part 2 is installed in mounting slot 11; The moving part 2 includes a cam assembly 21, which, when rotating about the axis of the mounting groove 11, is adapted to push the trim piece 6 to move via the cam assembly 21 for gap adjustment.

[0031] In some embodiments, the fixing part 1 serves as the body of the adjustment mechanism 100 and is used to mount or fix components such as the moving part 2. Specifically, for example... Figure 1 or Figure 2 As shown ( Figure 2 for Figure 1 The adjustment mechanism 100 (view after removing the moving part 2) is shown in the image. A mounting groove 11 is provided on the fixing part 1. The mounting groove 11 is a cylindrical groove structure provided on the fixing part 1. The cross-section of the mounting groove 11 is circular, and it extends in the same direction as one side edge of the fixing part 1. That is, the extension direction of the mounting groove 11 is not necessarily parallel to the edge, as long as the direction is the same (including parallelism). Considering that it is difficult to make the edge of the fixing part 1 a standard straight edge in practical applications, as long as the extension direction of the mounting groove 11 is the same as any edge of the fixing part 1, it is within the scope of protection of this application. For the mounting groove 11, in some embodiments, its extension direction should be a straight line. This design is because the moving part 2 needs to be installed in the mounting groove 11 and rotate within the mounting groove 11 around its axis (i.e., the cylindrical axis of the cylindrical mounting groove 11). In some embodiments, the moving part 2 is a cylindrical structure, and its arc-shaped outer surface fits against the arc-shaped inner surface of the mounting groove 11. Figure 3 or Figure 5 As shown, the moving part 2 is provided with a cam assembly 21, which protrudes from the cylindrical outer surface of the moving part 2. At least a portion of the circular cross-section of the mounting groove 11 has an opening that penetrates the fixing part 1 along the radial direction of the circular cross-section, and the opening extends along the axial direction of the mounting groove 11. This opening is defined as the first opening 15, and the moving part 2 is installed in the mounting groove through the first opening 15. The fixing part 1 has a second notch in the area opposite to the snap-fit ​​part 3. The second notch penetrates the fixing part 1 and connects the mounting groove 11 and the snap-fit ​​part 3. When the moving part 2 is assembled with the mounting groove 11 through the first opening 15, the cam assembly 21 can be accommodated in the second notch by rotating the moving part 2, thereby achieving contact engagement with the snap-fit ​​part 3 to adjust the gap of the trim.

[0032] In some embodiments, at least a portion of the circular cross-section of the mounting groove 11 has an opening that penetrates the fixing portion 1 radially along the circular cross-section, extends along the axial direction of the mounting groove 11, and does not penetrate the fixing portion 1 on either side of the mounting groove 11. In some embodiments, the moving portion 2 is mounted in the mounting groove 11 of the fixing portion 1 through the first opening 15, and is axially limited by the first end 12 and the second end 13 on both sides of the mounting groove 11. The axial direction is the axial direction of the mounting groove 11. Figure 8 As shown, radial limiting is achieved through the combined action of the limiting component 14 located outside the first opening 15 and the inner wall of the mounting groove 11. Radial refers to the radial direction of the circular cross-section of the mounting groove 11. For better radial limiting effect, such as... Figure 9 As shown, the limiting component 14 may include a first limiting component 141 and a second limiting component 142, which are respectively disposed opposite to each other outside the first opening 15. After the moving part 2 squeezes through the limiting component 14 and is installed in the mounting groove 11, the first limiting component 141 is positioned above and the second limiting component 142 is positioned below, thus radially limiting the moving part 2. To ensure that the moving part 2 can smoothly pass through the first opening 15 and squeeze into the mounting groove 11, at least one of the materials of the fixing part 1 in the mounting groove 11 area or the moving part 2 is required to have a certain degree of elasticity, so that it can return to its original shape after deformation.

[0033] In some embodiments, multiple limiting components 14 may be evenly arranged along the axial direction of the mounting groove 11.

[0034] In some embodiments, after the moving part 2 is installed in the mounting slot 11, rotating the moving part 2 can cause the cam assembly 21 to push the trim 6 to move in order to adjust the gap between the trim 6 and the trim mating part 7.

[0035] In some embodiments, the motion part 2 further includes an adjustment component for adjusting the movement of the body assembly 22 within the mounting slot 11.

[0036] In some embodiments, an adjustment component is provided on one end face of the moving part 2, and a second opening 16 is provided on the first end 12 and / or the second end 13 on both sides of the mounting groove 11, the second opening 16 penetrating through the first end 12 and / or the second end 13. The adjustment component is disposed relative to the second opening 16.

[0037] In some embodiments, the adjustment tool can cooperate with the adjustment assembly through the second opening 16 to adjust the rotation of the moving part 2.

[0038] In some embodiments, the cam assembly 21 and the moving part 2 can be integrally formed, and the specific process may include, but is not limited to, common plastic molding processes such as injection molding and 3D printing, and the material may be common plastic materials such as PP and ABS.

[0039] In some embodiments, the fixing part 1 can be manufactured by common plastic molding processes such as injection molding and 3D printing, and its material can be common plastic materials such as PP and ABS.

[0040] In some embodiments, when the cam assembly 21 rotates about the axis of the fixed part 1 in a first direction, it is adapted to push the trim 6 toward the trim fitting 7 to reduce the gap adjustment.

[0041] In some embodiments, when the cam assembly 21 rotates about the axis of the mounting groove 11 in the second direction, the trim 6 is adapted to move away from the trim mating member 7 under its own elastic force in order to increase the gap adjustment.

[0042] like Figure 13 or Figure 14 As shown, in some embodiments, the first direction can be counterclockwise, and correspondingly, the second direction is clockwise. The key point is that when the cam assembly 21 moves along the first direction, the cam tip of the cam assembly 21 moves towards the trim 6, and then, as the cam assembly 21 rotates, it gradually pushes the trim 6 towards the trim mating member 7 to adjust the gap between the trim 6 and the trim mating member 7. Correspondingly, when the cam assembly 21 moves along the second direction, the cam tip of the cam assembly 21 moves away from the trim 6. At this time, the trim 6 is adapted to move away from the trim mating member 7 under its own elastic force to adjust the gap between the trim 6 and the trim mating member 7. During the above gap adjustment process, the trim mating member 7 remains stationary.

[0043] In some embodiments, the adjustment mechanism 100 further includes: The snap-fit ​​part 3 is fixedly connected to the fixed part 1. When the moving part 2 rotates around the axis of the mounting groove 11, the cam assembly 21 pushes the snap-fit ​​part 3. The snap-fit ​​part 3 is adapted to push the trim piece 6 to move for gap adjustment.

[0044] In some embodiments, the snap-fit ​​part 3 can be integrally formed with the fixing part 1, or it can be a separate component assembled onto the fixing part 1. Importantly, the snap-fit ​​part 3 needs to have a certain degree of elasticity. When the moving part 2 rotates around the axis of the mounting groove 11, the cam assembly 21 rotates together with the moving part 2. The cam assembly 21 first pushes the snap-fit ​​part 3 to move, and then pushes the ornament 6 to move through the snap-fit ​​part 3, so as to adjust the gap between the ornament 6 and the ornament mating part 7. That is, the snap-fit ​​part 3 is disposed between the cam assembly 21 and the ornament 6.

[0045] In some embodiments, when the cam assembly 21 rotates about the axis of the fixed part 1 in the first direction, it is adapted to first push the locking part 3, and then push the ornament 6 towards the direction of the ornament fitting part 7 through the locking part 3, so as to reduce the gap adjustment.

[0046] In some embodiments, when the cam assembly 21 rotates about the axis of the mounting groove 11 in the second direction, the trim 6 and the snap-fit ​​portion 3 are adapted to move away from the trim mating member 7 under the action of their own elasticity in order to increase the gap adjustment.

[0047] In some embodiments, the first direction can be counterclockwise, and correspondingly, the second direction is clockwise. The key point is that when the cam assembly 21 moves along the first direction, the cam tip of the cam assembly 21 moves towards the trim 6. Then, as the cam assembly 21 rotates, it gradually pushes the locking part 3 towards the trim 6, and then pushes the trim 6 towards the trim fitting 7 via the locking part 3, thereby reducing the gap between the trim 6 and the trim fitting 7. Correspondingly, when the cam assembly 21 moves along the second direction, the cam tip of the cam assembly 21 moves away from the trim 6. At this time, the trim 6 and the locking part 3 are adapted to move away from the trim fitting 7 under their own elastic force, thereby increasing the gap between the trim 6 and the trim fitting 7. During the above gap adjustment process, the trim fitting 7 remains stationary.

[0048] In some embodiments, the cam assembly 21 pushes the latching portion 3, which is adapted to push the flange 61 of the trim 6, causing the trim 6 to move for gap adjustment.

[0049] In some embodiments, such as Figure 13 As shown, the trim 6 includes an outer surface and a flange 61, with a certain angle between the flange 61 and the outer surface. In some embodiments, the angle is between 0 degrees and 180 degrees.

[0050] In some embodiments, the cam assembly 21 pushes the locking part 3 to move, and the locking part 3 then pushes the flange 61 of the ornament 6, thereby driving the ornament 6 to move and adjusting the gap between the ornament 6 and the ornament mating part 7.

[0051] In some embodiments, because the size of the ornament 6 that mates with the snap-fit ​​part 3 is relatively large, the number of snap-fit ​​parts 3 is usually set to multiple, considering factors such as cost and weight. These multiple snap-fit ​​parts 3 are spaced apart on the fixing part 1. Correspondingly, the number of cam assemblies 21 is also multiple, corresponding one-to-one with the number and position of the snap-fit ​​parts 3. Besides adjusting the gap and surface difference between the ornament 6 and the ornament mating part 7, the snap-fit ​​part 3 also mates with the second toothed structure 611 on the flange 61 of the ornament 6 to fix the ornament 6. In some embodiments, the interval between two adjacent snap-fit ​​parts 3 can be 50-200mm. This distance setting can ensure optimal cost and weight while providing good fixation for the ornament 6. That is, when the length of the flange 61 that mates with the ornament 6 and the snap-fit ​​part 3 is greater than or equal to 100mm, the ornament 6 is considered to be relatively large.

[0052] In some embodiments, a first toothed structure 31 is provided on the end face of the latching part 3 that contacts the cam assembly 21. The first toothed structure 31 is used to limit the cam assembly 21 when it rotates to a specific position. The limiting principle is that when the cam assembly 21 pushes the latching part 3 towards the ornament 6, the cam assembly 21 contacts the latching part 3 and exerts a pushing force on the latching part 3 towards the ornament 6, causing the latching part 3 to move out of its initial position (i.e., a free state without external force). Conversely, the latching part 3, because of its elasticity, exerts a reaction force on the cam assembly 21. When the cam assembly 21 no longer moves actively, the first toothed structure 31, under the action of the reset elasticity, presses the cam assembly 21. The purpose of the toothed structure is to increase the friction between the cam assembly 21 and the latching part 3, thereby limiting the cam assembly 21. In some embodiments, the first toothed structure 31 can also be other uneven surfaces that increase friction, all of which are within the scope of protection of this application and will not be described in detail here.

[0053] In some embodiments, a specific position refers to the position of the cam assembly 21 after the gap of the trim piece 6 has been adjusted by rotating the cam assembly 21.

[0054] In some embodiments, the motion part 2 further includes a body assembly 22, which is fixedly connected to the cam assembly 21 and is installed in the mounting groove 11.

[0055] In some embodiments, the body assembly 22 and the cam assembly 21 can be integrally formed or are separate components assembled together. The moving part 2 is mounted in the mounting groove 11 via the body assembly 22. In some embodiments, the body assembly 22 is mounted in the mounting groove 11 through a first opening 15 and is axially limited by the first end 12 and the second end 13 on both sides of the mounting groove 11. Radial limitation is achieved by the combined action of the limiting component 14 disposed outside the first opening 15 and the inner wall of the mounting groove 11.

[0056] In some embodiments, at least one cam assembly 21 is provided along the axial direction of the body assembly 22. The number and position of the cam assembly 21 correspond one-to-one with those of the snap-fit ​​portion 3.

[0057] In some embodiments, an adjustment groove 221 is provided on one end face of the body assembly 22. The adjustment groove 221 is disposed opposite to the second opening 16, and the adjustment groove 221 is used to adjust the movement of the body assembly 22 within the mounting groove 11. An adjustment tool can cooperate with the adjustment groove 221 through the second opening 16 to adjust the rotation of the moving part 2. Specifically, the adjustment groove 221 may include, but is not limited to, a straight groove, a cross-shaped groove, etc. As long as the adjustment tool can cooperate with it, the rotation of the adjustment tool to drive the moving part 2 to rotate is within the scope of this application. When the adjustment groove 221 is a straight groove or a cross-shaped groove, the joint portion of the adjustment tool that cooperates with it has a straight or cross-shaped structure.

[0058] In some embodiments, such as Figure 4 As shown, the adjustment groove 221 can be recessed into at least one end face of the body assembly 22; or it can be formed by a feature protruding from at least one end face of the body assembly 22. Figure 6 As shown, the adjustment groove 221 is formed by symmetrically arranging two bosses with a minor arc-shaped cross-section, and the area between the two bosses is the adjustment groove 221. In some embodiments, the end face projections of the two bosses are within the end face projections of the body assembly 22. When the body assembly 22 is a cylindrical structure, the projection direction is along the axis of the body assembly 22. Figure 7 As shown, the arc surfaces of the two bosses fit against the inner surface of the second opening 16. When the body assembly 22 is assembled with the mounting groove 11, the two boss structures can not only form an adjustment groove 221, but also limit the body assembly 22 radially. It should be noted that in order to smoothly install the body assembly 22 with the two boss structures into the mounting groove 11, two feasible solutions are given here: Solution 1 requires that at least one of the body assembly 22 or the fixing part 1 is elastic, that is, it can return to its original shape after deformation, so that assembly can be achieved by the deformation of at least one of them; Solution 2, a third notch can be opened on the first end 12, and the two boss structures can be squeezed into the mounting groove through the third notch to achieve assembly.

[0059] In some embodiments, the snap-fit ​​portion 3 includes a snap-fit ​​body and a snap-fit ​​assembly 32, the snap-fit ​​body and the snap-fit ​​assembly 32 being fixed together, and the snap-fit ​​assembly 32 protruding from the snap-fit ​​body. The snap-fit ​​assembly 32 protruding from the snap-fit ​​body is adapted to engage with a second toothed structure 611 provided on the trim piece 6, such as... Figure 10 and Figure 11 The diagram shows a schematic of the toothed structure on the ornament 6. The snap-fit ​​component 32 is embedded into the recessed features of the toothed structure, thus securing the ornament 6 to the snap-fit ​​component 3. Simultaneously, the second toothed structure 611 comprises multiple sets of sequentially arranged recessed and protruding features. By adjusting the snap-fit ​​component 32 in conjunction with different recessed features, the surface difference between the ornament 6 and the mating part 7 can be adjusted.

[0060] In some embodiments, the side end face of the latching portion 3 that contacts the cam assembly 21 is provided with a first toothed structure 31; the latching assembly 32 is disposed away from the first toothed structure 31, that is, the latching assembly 32 is provided on the side end face of the latching body near the ornament 6, and the first toothed structure 31 is provided on the side end face near the cam assembly 21. The latching assembly 32 is adapted to cooperate with the second toothed structure 611 provided on the ornament 6 to adjust the surface difference of the ornament 6. The first toothed structure 31 is adapted to cooperate with the cam assembly 21 to limit the cam assembly 21.

[0061] In some embodiments, a second toothed structure 611 is provided on the flange 61 of the trim 6, and the snap-fit ​​component 32 is adapted to cooperate with the second toothed structure 611 provided on the flange 61 of the trim 6 to adjust the surface difference of the trim 6 along the extension direction of the flange 61. The flange 61 refers to the surface feature formed by extending from one edge line of the outer surface of the trim 6 away from the starting line. The flange 61 has a certain angle with the outer surface. Therefore, the extension direction of the flange 61 refers to the direction perpendicular to the starting line on the end face of the flange 61 away from the end face where the second toothed structure 611 is located.

[0062] The vehicle according to a second aspect of the present invention includes the adjustment mechanism 100 described above.

[0063] In some embodiments, the trim piece 6 can be a decorative part such as the front or rear bumper of a vehicle. Therefore, there can be multiple adjustment mechanisms 100, that is, each adjustment mechanism 100 corresponds to one trim piece 6, so as to adjust the gap and surface difference between the trim piece 6 and the trim piece mating part 7 respectively.

[0064] In some embodiments, when trim piece 6 is a front bumper, trim piece mating piece 7 is a fender. In this case, adjustment mechanism 100 can be connected to at least one of the front bumper and the fender to adjust the gap and surface difference between the front bumper and the fender.

[0065] In some embodiments, the vehicle further includes a mounting module, which may include, but is not limited to, the vehicle body or chassis. The adjustment mechanism 100 is directly or indirectly fixed to the mounting module, and the specific connection method may include, but is not limited to, welding or screwing. The trim piece 6 is fixed to the adjustment mechanism 100 to achieve the installation of the trim piece 6.

[0066] In some embodiments, an adjustment mechanism 100 is provided to be indirectly fixed to the mounting module. Specifically, the adjustment mechanism 100 is a bumper mounting bracket, which uses a positioning pin 4 to engage with a positioning hole on the fender front mounting plate 8 to position the bumper mounting bracket and the fender front mounting plate 8. Then, a second fastener passes through a mounting hole 5 to assemble with the fender front mounting plate 8, thus fixing the bumper mounting bracket to the fender front mounting plate 8. The fender front mounting plate 8 can be assembled to the fender front mounting plate 8 by using a first mounting hole (suitable for both metal and non-metal materials) or by welding a back-welded nut (suitable for metal materials) to engage with the second fastener. The fender front mounting plate 8 is then fixed to the mounting module by using a third fastener passing through the second mounting hole on the fender front mounting plate 8 to engage with a corresponding hole on the vehicle. In this case, the mounting module is the vehicle body, and the fender front mounting plate 8 is installed in the front compartment area of ​​the vehicle body. In some embodiments, the fender front end fixing plate 8 is connected to the front end of the fender body via a first fastener 9. In some embodiments, the first fastener 9 may include, but is not limited to, fastening structures such as rivets. The main function of the fender front end fixing plate 8 is to enhance the stability of the front end of the fender body. The main function of the bumper mounting bracket is to fix the front bumper. The front bumper is an outer covering, and to maintain the aesthetic appearance of the vehicle, the outer covering typically does not use bolts, screws, or other connection methods; that is, it is fixed to the bumper mounting bracket via a snap-fit ​​structure.

[0067] In this application, the adjustment mechanism 100 includes a fixed part 1, a moving part 2, and a locking part 3. The main body assembly 22 of the moving part 2 rotates in a first direction around the axis of the mounting groove 11 within the mounting groove 11 of the fixed part 1, driving the cam assembly 21 of the moving part 2 to rotate. The cam assembly 21 pushes the locking part 3 towards the flange 61 of the ornament 6. During the movement, the locking part 3 pushes the flange 61 of the ornament 6 towards the ornament mating part 7, thereby causing the ornament 6 to move towards the flange 61 of the ornament 6, thereby reducing the gap between the ornament 6 and the ornament mating part 7. When the main body assembly 22 of the moving part 2 rotates in a second direction around the axis of the mounting groove 11 within the mounting groove 11 of the fixed part 1, it drives the cam assembly 21 of the moving part 2 to rotate. At this time, the cam assembly 21 gradually releases the force pushing the locking part 3 towards the flange 61 of the ornament 6. Under its own elastic force, the ornament 6 and the locking part 3 move away from the ornament mating part 7, that is, the locking part 3 and the ornament 6 follow the cam assembly 21 towards the area of ​​the locking part 3. This is to increase the gap adjustment. The locking assembly 32 is adapted to engage with the second toothed structure 611 provided on the flange 61 of the ornament 6. The second toothed structure 611 includes multiple sets of sequentially arranged recessed and protruding features. The locking assembly 32 is embedded in the recessed features of the toothed structure. By adjusting the engagement of the locking assembly 32 with different recessed features, the surface difference between the ornament 6 and the ornament mating part 7 can be adjusted.
