Description

Tolerance absorption kit and vehicle equipped with it TECHNICAL FIELD

[0001] The embodiments of the present invention relate to the technical field of vehicle production and manufacturing and, in particular, to a tolerance absorption assembly and the vehicle equipped with it. BACKGROUND

[0002] With the current trend in light vehicle manufacturing, when assembling any other component, fasteners such as bolts or rivets must pass through predefined mounting holes in the components to be mounted and in the thin-walled plates. These components are then secured to the thin-walled plates by screwing in the bolts or riveting them. Due to existing manufacturing tolerances in both the components to be mounted and the thin-walled plates, inserting the bolts or rivets into the mounting holes can be impossible or difficult. Therefore, it becomes necessary to adjust the positions of the components to be mounted or the thin-walled plates and reinsert the bolts, which reduces assembly efficiency. Therefore, there is an urgent need to provide a structure or assembly capable of accommodating these tolerances to improve assembly efficiency. SUMMARY OF THE INVENTION

The base further includes a projection disposed on the second hole portion, and this projection is separated from the limiting surface. The adjustable fastening element includes a fastening portion and a limiting portion.The fixing portion is arranged in and separated from the first hole portion, the limiting portion is arranged in and separated from the second hole portion, and the limiting portion abuts against the limiting surface in an axial direction of the second hole portion. The bushing fits between the projection and the limiting portion.

[0005] In some embodiments of the present invention, the tolerance absorption assembly further includes a housing. This housing defines a mounting hole, the base is disposed in the mounting hole, a threaded portion is disposed in a wall defining said mounting hole, a threaded groove is defined in a side wall of the base facing the mounting hole, the threaded portion and the threaded groove extend in an axial direction of the base, and the threaded portion engages in the threaded groove.

[0006] In some embodiments of the present invention, in an axial direction of the mounting hole, the width of the threaded groove is greater than the width of the threaded portion.

[0007] In some embodiments of the present invention, a guide opening is defined on one side of the threaded groove. In a radial direction of the mounting hole, the depth of the guide opening is greater than the depth of the threaded groove; and / or in a peripheral direction of the mounting hole, the width of the guide opening is greater than the width of the threaded groove.

[0008] In some embodiments of the present invention, the diameter of the fixing portion is less than the diameter of the limiting portion, the fixing portion passes through the first hole portion, the limiting portion being disposed in the second hole portion and a fixing thread being formed in such fixing portion.

[0009] In some embodiments of the present invention, the base includes a plurality of projections, said plurality of projections being arranged at intervals on a wall of the hole of the second hole portion, said plurality of projections being separated from the limiting surface in the axial direction of the second hole portion to form a coupling groove, and this coupling groove being configured to couple with the bushing.

[0010] In some embodiments of the present invention, the bushing defines a first avoidance hole and one or more second avoidance holes. A portion of the adjustable fastening element is located in the first avoidance hole, and the one or more second avoidance holes are arranged on an outer side of the first avoidance hole in a radial direction from the first avoidance hole. The plurality of second avoidance holes are arranged at intervals in the radial direction from the first avoidance hole, and each of said plurality of second avoidance holes is a circular arc-shaped hole.

[0011] In some embodiments of the present invention, the bushing defines a guide groove, said guide groove being located on the outside side of the first avoidance hole in the radial direction of the first avoidance hole, the guide groove is located between the adjacent second avoidance holes in the radial direction of the first avoidance hole, and an opening of the guide groove is defined on a side opposite said first avoidance hole.

[0012] In some embodiments of the present invention, the bushing further includes a plurality of coupling portions, said plurality of coupling portions being located on an outer side of one of the corresponding plurality of second avoidance holes in the radial direction of said bushing, and the plurality of coupling portions and the plurality of second avoidance holes being in mutual correspondence.

[0014] The tolerance absorption assembly and vehicle provided by some embodiments of the present invention can have the following effects: the base is used to mount the component to be mounted on a thin-walled plate; the base forms the first hole portion and the second hole portion; the fixing portion is disposed in the first hole portion and separated from the first hole portion, while the limiting portion is disposed in the second hole portion and separated from the second hole portion. When mounting the component on the thin-walled plate using the fixing portion, if there is a mounting tolerance between the component to be mounted and a defined fixing hole in the thin-walled plate, the fixing portion is movable in the first hole portion, while the limiting portion is movable in the second hole portion.In this way, the mounting tolerance between the component to be mounted and the thin-walled plate can be absorbed by the adjustable fixing element when the component to be mounted is clamped or locked to the thin-walled plate using the adjustable fixing element. The diameter of the first hole portion is smaller than the diameter of the second hole portion to form the limiting surface. The limiting portion rests against the limiting surface in the axial direction of the second hole portion, so that the adjustable fixing element can secure the component to be mounted to the thin-walled plate. The housing includes the projection provided in the second hole portion. This projection can be separate from the aforementioned limiting surface. The bushing can be clamped or engaged with the projection in a radial direction of the second hole portion.The bushing can also act as a stop between the projection and the limiting portion in the axial direction of the second hole portion. After securing the adjustable fastener, in the axial direction of the second hole portion, the limiting portion can be further restricted by the interaction between the bushing and the limiting surface, in order to reduce the possibility of the adjustable fastener becoming disengaged.

[0026] The following will describe in greater detail embodiments of the present invention with reference to the accompanying drawings. However, the embodiments can be implemented in various ways and should not be interpreted as limited to the examples described herein. Rather, these embodiments are provided to make the present invention more complete and comprehensive, and to fully convey the concept of the embodiments to those skilled in the art.

[0027] Furthermore, the described features, structures, or properties may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to enable a thorough understanding of some embodiments of the present invention. However, those skilled in the art will recognize that the technical solutions of the present invention may be implemented without one or more of the specific details, or that other methods, components, apparatus, steps, etc., may be employed. In other cases, well-known methods, apparatus, implementations, or operations are neither shown nor described in detail to avoid obscuring aspects of the present invention.

[0028] The present invention will be described in more detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the technical features involved in some embodiments of the present invention described below may be combined with each other provided they do not conflict. The embodiments described below with reference to the accompanying drawings are illustrative and intended to explain the present invention, and should not be construed as limiting it.

[0029] It should be noted that the term "a plurality," as used herein, denotes two or more. The expression "and / or" describes the relationship of association between associated objects, indicating that there can be three relationships. For example, A and / or B can indicate three situations, including: A exists alone, A and B exist simultaneously, or B exists alone. The character " / " generally indicates that the relationship between the preceding and following associated objects is "or."

[0030] Given the current trend toward lighter automobiles, when mounting any other component, fasteners such as bolts or rivets must pass through predefined mounting holes in the components to be mounted and in the thin-walled plates. The components to be mounted are then secured to the thin-walled plates by screwing in the bolts or riveting them in. Due to existing manufacturing tolerances in both the components to be mounted and the thin-walled plates, it may be impossible or difficult to insert the bolts or rivets into the mounting holes. Therefore, it is necessary to adjust the positions of the components to be mounted or the thin-walled plates and reinsert the bolts, which reduces assembly efficiency. Therefore, there is an urgent need for a structure capable of accommodating these tolerances to improve assembly efficiency.

[0031] To solve the above technical problems, as shown in Figure 1, some embodiments of the present invention provide a tolerance absorption assembly. This tolerance absorption assembly may include a base 10, an adjustable locking or fastening element 20, and a bushing 30. When a component is mounted to a vehicle body, the tolerance between the component to be mounted and the vehicle body can be absorbed by the cooperation of the base 10, the adjustable locking element 20, and the bushing 30.

[0032] In some embodiments, as shown in Figure 2, the base 10 may form a first hole portion 11 and a second hole portion 12. The diameter of the first hole portion 11 may be smaller than that of the second hole portion 12, so that a limiting surface 13 may be formed. The base 10 may include a projection 14 disposed in the second hole portion 12. This projection 14 may be separate from the aforementioned limiting surface 13. The adjustable fastening element 20 may include a fastening portion or a locking portion and a limiting portion 22. The fastening portion 21 may be disposed in the first hole portion 11 and separate from the first hole portion 11. The limiting portion 22 may be disposed in the second hole portion 12 and separate from the second hole portion 12.The limiting portion 22 can abut against the limiting surface 13 in an axial direction of the second hole portion 12. The bushing 30 can be held or coupled between the fan 14 and the limiting portion 22. In this case, the base 10 can be used for mounting the component to be mounted on a thin-walled plate; said base 10 can form the first hole portion 11 and the second hole portion 12; the fixing portion 21 can be arranged in the first hole portion 11 and separate from the first hole portion 11; and the limiting portion 22 can be arranged in the second hole portion 12 and separate from said second hole portion 12.When the component to be mounted is mounted to the thin-walled plate using the fixing portion 20, if there is a mounting tolerance between the component to be mounted and a defined fixing hole in the thin-walled plate, the fixing portion 21 is able to move or shift in the first hole portion 11, while the limiting portion 22 is movable in the second hole portion 12. In this way, the mounting tolerance between the component to be mounted and the thin-walled plate can be absorbed by the adjustable fixing element 20 when the component to be mounted is clamped or locked to the thin-walled plate using the adjustable fixing element 20. The diameter of the first hole portion 11 can be smaller than the diameter of the second hole portion 12 to form the limiting surface 13.This limiting portion 22 can abut against the limiting surface 13 in the axial direction of the second hole portion 12, so that the adjustable fixing element 20 can secure the component to be mounted to the thin-walled plate. The housing assembly 40 can include a projection 14 arranged on the second hole portion 12. This projection 14 can be separate from the limiting surface 13. The bushing 30 can be clamped or engaged with the projection 14 in a radial direction of the second hole portion 12. The bushing 30 can also abut between the projection 14 and the limiting portion 22 in the axial direction of the second hole portion 12.Once the adjustable fastening element 20 is fixed in the axial direction of the second hole portion 12, the limiting portion 22 can be limited by the cooperation of the bushing 30 and the limiting surface 13, in order to reduce the possibility of the adjustable fastening element 20 becoming disengaged.

[0033] In some embodiments, as shown in Figure 2, a space can be defined in the axial direction of the second hole portion 12, between the limiting portion 22 and the limiting surface 13. When the fixing portion 21 is fixed and locked with the component to be mounted, the adjustable fixing element 20 can move in the radial direction of the second hole portion 12 between the bushing 30 and the limiting surface 13.

[0034] In some embodiments, as shown in Figures 3 and 4, the tolerance absorption assembly may further include a housing 40. This housing 40 may define a mounting hole 41. The base 10 may be disposed in the mounting hole 41. A threaded portion 411 may be disposed in a defined wall of the mounting hole 41. A threaded groove 15 may be defined on a side wall of the base 10 facing the mounting hole 41. The threaded portion 411 and the threaded groove 15 may extend axially from the base 10. The threaded portion 411 may be disposed in the threaded groove 15. The housing 40 may be integrated into the thin-walled plate of a vehicle, or the housing 40 may be a separate component independent of the thin-walled plate of the vehicle. The mounting hole 41 defined in the housing 40 may be configured to mount or accommodate the base 10.The base 10 can be rotatably mounted in the mounting hole 41 along an axial direction of said mounting hole 41 by means of the cooperation between the threaded portion 411 and the threaded groove 15. In some embodiments, the first hole portion 11 can be located on a side close to the vehicle's thin-walled plate, while the second hole portion 12 can be located on a side farther from the vehicle's thin-walled plate. After mounting the adjustable fastening element 20 in the first hole portion 11 and the second hole portion 12, the fastening portion 21 of the adjustable fastening element 20 can pass through the first hole portion 11 and extend to the defined fastening hole in the thin-walled plate, so that the housing 40 and the base 10 can be fixed to the thin-walled plate by means of said adjustable fastening element 20.

[0035] In some embodiments, as shown in Figures 3 and 4, several threaded portions 411 can be arranged at intervals in the radial direction of the mounting hole 41, and several threaded grooves 15 can be arranged at intervals in the radial direction of said mounting hole 41. Each threaded portion 411 and a corresponding threaded groove 15 can mesh with each other. On one side of each threaded groove 15, a guide opening 151 can be defined, and this guide opening 151 can be configured to guide the corresponding threaded portion 411 when it engages in the threaded groove 15. In some embodiments, for each threaded groove 15, the depth of the guide opening 151 can be greater than the depth of the threaded groove 15 in the radial direction of the mounting hole 41, while the width of the guide opening 151 can be greater than the width of the threaded groove 15 in a peripheral direction of the mounting hole 41.

[0036] In some embodiments, as shown in Figure 2, the width of the threaded groove 15 may be greater than the width of the threaded portion 411 in the axial direction of the mounting hole 41, thereby forming a gap between said threaded portion 411 and the side wall of said threaded groove 15. The configuration of this gap may allow adjustment of the relative positions of the base 10 and the housing 40, permitting the base 10 to move in the axial direction of the mounting hole 41. In this way, tolerances between the housing 40, the thin-walled plate, and the base 10 may be absorbed by displacing the base 10 and the housing 40 in the axial direction of the mounting hole 41, which may facilitate the assembly of the housing 40, the thin-walled plate, and the base 10.Once the base 10 is mounted in the mounting hole 41, the adjustable fixing element 20 can be locked in place, allowing it to be engaged with the fixing hole defined in the thin-walled plate. If the tolerances of the thin-walled plate and / or the housing 40 result in a larger mounting tolerance between the thin-walled plate and the housing 40, this tolerance can be absorbed by adjusting the axial displacement of the base 10, without needing to adjust the relative positions of the thin-walled plate and the housing 40, thus simplifying the assembly process. In some embodiments, the distance between the threaded portion 411 and the side wall of the threaded groove 15 can be between 0 and 5 mm.

[0037] In some embodiments, as shown in Figure 2, the mounting hole 41, the first hole portion 11, and the second hole portion 12 may be arranged coaxially, and the first hole portion 11 may communicate or couple with the second hole portion 12. The communication between the first hole portion 11 and the second hole portion 12 allows the fixing portion 21 of the adjustable fixing element 20 to be placed in the first hole portion 11, while the limiting portion 22 of the adjustable fixing element 20 is placed in the second hole portion 12. Furthermore, the first hole portion 11 and the second hole portion 12 are arranged coaxially, so that the difficulty of defining a hole in the base 10 can be reduced.In the case where mounting hole 41, the first portion of hole 11 and the second portion of hole 12 are arranged coaxially, it is also possible to reduce the difficulty of defining mounting hole 41.

[0038] In some embodiments, as shown in Figure 2, the diameter of the fixing portion 21 may be smaller than the diameter of the limiting portion 22. The fixing portion 21 may pass through the first hole portion 11. The limiting portion 22 may be arranged in the second hole portion 12. A fixing thread 211 may be formed in the fixing portion 21. A first space D1 may be formed between the fixing portion 21 and a wall of the first hole portion 11. Furthermore, a second space D2 may be defined between the limiting portion 22 and the second mounting hole 41. The length of said first space D1 in a radial direction of the first hole 11 may be between 0 and 3 mm. In turn, the length of said second space D2 in the radial direction of the second hole portion 12 may be greater than the length of said first space D1.As shown in Figure 2, the first gap D1 can be defined as the space defined in the radial direction of the first hole portion 11 and between the left side of the fixing portion 21 and the hole wall of the first hole portion 11. A separation defined in the radial direction of the first hole portion 11 and between the right side of the fixing portion 21 and the hole wall of the first hole portion 11 can also be defined as the first gap D1. The displacement distance of the fixing portion 21 on one side in the radial direction can be from 0 to 1.5 mm. The displacement distance of the fixing portion 21 on both sides in the radial direction can be between 0 and 3 mm; that is, the tolerance range that the adjustable fixing element 20 can absorb in the radial direction can be between 0 and 3 mm.

[0039] In some embodiments, as shown in Figure 2, the base 10 may include a plurality of projections 14. This plurality of projections 14 may be arranged at intervals on the wall of the second hole portion 12. The plurality of projections 14 may be separated from the limiting surface 13 in the axial direction of the second hole portion 12, so that a coupling or clamping groove 16 may be formed between the plurality of projections 14 and the limiting surface 13. The coupling groove 16 may be configured to engage with the bushing 30, i.e., the bushing 30 may fit or engage in said coupling groove 16.Each projection 14 may have a first width in the radial direction of the second hole portion 12, and the first width of the projection 14 gradually increases in the axial direction from the side far from the limiting surface 13 to the side near the limiting surface 13. In the axial direction of the second hole portion 12, between the plurality of projections 14 and the limiting surface 13, a third space D3 may be formed. The width of the mating groove 16 in the axial direction of the second hole portion 12 may be greater than the width of the limiting portion 22 and the bushing 30.When the bushing 30 moves near the first hole portion 11 from the far side of the first hole portion 11 and moves further to engage in the engagement groove 16, the limiting portion 22 can abut against the limiting surface 13, and the bushing 30 can abut between the limiting portion 22 and the projection 14. The position of the limiting portion 22 in the axial direction of the second hole portion 12 can be fixed by the bushing 30. However, since the width of the engagement groove 16 in the axial direction of the second hole portion 12 is greater than the width of the limiting portion 22 and the bushing 30, the limiting portion 22 can shift between the bushing 30 and the limiting surface 13, so that the limiting portion 22 can move in the radial direction of the second hole portion 12.

[0040] In some embodiments, as shown in Figure 5, the adjustable fastening element 20 may be a bolt. This bolt may include a nut 221, a flange 222, and a threaded stem. The nut 221, flange 222, and threaded stem may be configured as an integral structure. The flange 222 may be arranged between the nut 221 and the threaded stem. The nut 221 may be the head of the adjustable fastening element 20. The flange 222 may abut against the limiting surface 13. The fastening thread 211 may be formed on the threaded stem. Furthermore, the threaded stem may pass through the first portion of the hole 11 and be threaded into the defined fastening hole in the thin-walled plate to achieve fastening. The nut 221 may be configured to cooperate with a fastening tool. The flange 222 forms part of the limiting portion 22.In turn, the bushing 30 can stop between the flange 222 and the projection 14 in the axial direction of the second portion of hole 12.

[0041] In some embodiments, as shown in Figures 6 and 7, a first avoidance hole 31 and a second avoidance hole 32 may be defined in the bushing 30. A portion of the adjustable fastening element 20 may be located in the first avoidance hole 31. The second avoidance hole 32 may be located on an outer side of the first avoidance hole 31 in the radial direction of the first avoidance hole 31. In some embodiments, a plurality of second avoidance holes 32 may be defined. This plurality of second avoidance holes 32 may be arranged at intervals in a radial direction of the first avoidance hole 31. The plurality of second avoidance holes 32 may be circular arc-shaped holes. This bushing 30 may be circular or ring-shaped.The first clearance hole 31 can be a circular hole formed by defining a coaxial opening in the bushing 30. As shown in Figure 2, the head of the adjustable fastener 20 can pass through the first clearance hole 31. A fourth space D4 can be defined between a hole wall forming the first clearance hole 31 and the nut 221. In this way, the adjustable fastener 20 is movable in the first clearance hole 31, so that the adjustable fastener 20 can move in both the first hole portion 11 and the second hole portion 12 to absorb the tolerance. Furthermore, a clamping tool can be configured to enter the fourth space D4 and grip the head for rotational clamping.The second avoidance holes 32 may be arranged as circular arc holes surrounding the outer side of the first avoidance hole 31 in the radial direction of said first avoidance hole 31. A first side wall may be arranged between the second avoidance holes 32 and the first avoidance hole 31 in a radial direction of the bushing 30. In addition, a second side wall may be arranged on the side of the second avoidance hole 32 away from the first avoidance hole 31 in the radial direction of the bushing 30. The first side wall and the second side wall define support structures for the bushing 30.

[0042] In some embodiments, as shown in Figures 6 and 7, the bushing 30 may further include a plurality of coupling portions 34. Each of these coupling portions 34 may be located on an outer side of the corresponding second avoidance holes 32 in the radial direction of the first avoidance hole 31, and said coupling portions 34 and said second avoidance holes 32 may be mutually aligned. Each coupling portion 34 may be configured as a first side wall, and the coupling portion 34 may be engaged in the coupling groove 16.

[0043] In some embodiments, as shown in Figure 7, the bushing 30 may define a guide groove 33. This guide groove 33 may be located on the outer side of the first avoidance hole 31 in the radial direction of said first avoidance hole 31. Furthermore, the guide groove 33 may be located between adjacent second avoidance holes 32 in the radial direction of said first avoidance hole 31. On a side opposite the first avoidance hole 31, an opening 331 of the guide groove 33 may be defined. When the bushing 30 is inserted or engaged in the engagement groove 16, the guide groove 33 on the side opposite the first avoidance hole 31 may be displaced axially with respect to the projection 14. When the bushing 30 enters the engagement groove 16, said bushing 30 may rotate so that the engagement portions 34 may abut against said projection 14.

[0044] Some embodiments of the present invention may also relate to a vehicle that includes the tolerance absorption assembly mentioned above. Such a vehicle may further include a thin-walled plate and a handle component. The thin-walled plate may define a fixing hole. The handle component may be connected to the thin-walled plate via the tolerance absorption assembly. The handle component may be a concealed-type door handle. The tolerance between the handle component and the thin-walled plate may be absorbed by means of the tolerance absorption assembly when the handle component is positioned on the thin-walled plate. Assembly between the handle component and the thin-walled plate may thus be facilitated.
