Description

Technical Field

[0001] The utility model belongs to the field of vehicle door handle tolerance adjusters, and in particular relates to a spatial tolerance adjuster. Background Art

[0002] With the continuous development of new energy vehicles, the application of electric hidden handles is becoming more and more extensive, and the requirements for the functions and appearance of vehicles are gradually increasing.

[0003] Since the handle is made into a hidden type, compared with conventional handles, there is no direct matching installation structure between the handle and the door sheet metal. It is mainly installed on the reinforced sheet metal that matches the door panel. Since the door panel and the reinforced sheet metal are welded, the current technological level is limited, and there will be a large spatial error after welding. If the handle is directly installed on the reinforced sheet metal, the gap surface difference between the handle panel and the door panel will be too large, affecting the appearance. In some spatial tolerance adjusters, the limiting structure of the adjustment mechanism and the adjusting screw is relatively simple, and convenient disassembly and assembly cannot be achieved, which increases the difficulty of operation for workers and reduces work efficiency. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to propose a spatial tolerance adjuster that can achieve high-precision spatial position adjustment and has both position limiting and convenient assembly and disassembly effects.

[0005] The technical solution adopted by the utility model to solve the technical problem is to propose a spatial tolerance adjuster, comprising: a sheet metal part connected to an external component, a nut welded to the sheet metal part;

[0006] A mounting base, wherein at least one set of guide members is provided inside the mounting base;

[0007] an adjustment mechanism disposed in the mounting base, the adjustment mechanism being provided with an adjustment guide post, the adjustment guide post being movably connected to the guide member, and at least one snap-fastener strip being formed at a top end of the adjustment guide post, the snap-fastener strip being able to movably abut against the guide member when the adjustment guide post moves along the axial direction;

[0008] an adjusting screw, one end of which is movably pressed against the adjusting mechanism, and the other end of which passes through the sheet metal part and is threadedly connected to the nut;

[0009] The snap bar can be moved against the guide member when the adjustment mechanism drives the adjustment screw toward the sheet metal member, and can be separated from the guide member when the snap bar is elastically deformed under pressure, so that the adjustment mechanism can drive the adjustment screw to separate from the mounting base.

[0010] In the above-mentioned spatial tolerance adjuster, the outer wall of the snap strip protrudes outward to form an extension portion, and the bottom wall of the extension portion is provided with a guiding slope, and the guiding slope movably abuts against the guide member.

[0011] In the above-mentioned spatial tolerance adjuster, the snap strip and the adjustment guide column jointly form an L-shaped clearance groove.

[0012] In the above-mentioned spatial tolerance adjuster, the guide member is provided with first spiral guide ribs distributed in an annular manner, and the outer wall of the adjustment guide column is formed with second spiral guide ribs, which are movably connected to the first spiral guide ribs.

[0013] In the above-mentioned spatial tolerance adjuster, the adjustment mechanism also includes a centering block, which is movably engaged in the adjustment guide column and forms a guide cavity together with it. A tightening portion is formed on the adjustment screw, and the tightening portion is movably arranged in the guide cavity to allow the adjustment screw to move relative to the adjustment guide column along its radial direction.

[0014] In the above-mentioned spatial tolerance adjuster, positioning blocks are symmetrically arranged at the periphery of the centering block, a snap-fit ​​groove is formed in the positioning block, and a snap-fit ​​block is formed on the inner wall of the adjustment guide column, and the snap-fit ​​block is movably snapped into the snap-fit ​​groove.

[0015] In the above-mentioned spatial tolerance adjuster, arc blocks are symmetrically formed at the periphery of the centering block, and the arc blocks are movably pressed against the inner wall of the adjusting guide column.

[0016] In the above-mentioned spatial tolerance adjuster, a limiting boss is formed at the bottom of the adjusting guide post, and the limiting boss movably abuts against the sheet metal part.

[0017] In the above-mentioned spatial tolerance adjuster, an avoidance groove is also provided in the adjusting guide column. The engaging block can be squeezed and deformed along the avoidance groove when the positioning block is movably abutted, and can be movably engaged in the engaging groove aligned with it due to elastic deformation.

[0018] In the above-mentioned spatial tolerance adjuster, the outer diameter of the limiting boss is larger than the inner diameter of the first spiral guide rib and smaller than the inner diameter of the mounting base.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) The utility model provides a spatial tolerance adjuster that adjusts the Y-direction error by adjusting the guide column to move in the Y-direction in the mounting base. The adjusting screw can move in the X-direction and Z-direction planes to adjust the error in the XZ plane direction, thereby improving the positioning accuracy of the hidden handle and the door panel while ensuring the assembly accuracy of the tooling.

[0031] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0032] like Figures 1 to 5 As shown, the utility model is a spatial tolerance adjuster, comprising: a sheet metal part 1 connected to an external component, a nut 10 being welded on the sheet metal part 1; a mounting base 2, wherein at least one group of guide parts 20 are provided inside the mounting base 2; an adjusting mechanism 3, arranged in the mounting base 2, an adjusting guide column 30 is provided on the adjusting mechanism 3, the adjusting guide column 30 is movably connected to the guide part 20, and at least one spring buckle strip 300 is formed at the top end of the adjusting guide column 30, and the spring buckle strip 300 can be movably pressed against the guide part 20 when the adjusting guide column 30 moves along the axial direction; an adjusting screw 4, one end of the adjusting screw 4 is movably pressed against the adjusting mechanism 3, and the other end passes through the sheet metal part 1 and is threadedly connected to the nut 10; the spring buckle strip 300 can be movably pressed against the guide part 20 when the adjusting mechanism 3 drives the adjusting screw 4 toward the sheet metal part 1, and disengage from the guide part 20 when the spring buckle strip 300 is elastically deformed under pressure, so that the adjusting mechanism 3 can drive the adjusting screw 4 to disengage from the mounting base 2.

[0033] Before adjusting the tolerance in this embodiment, the nut 10 is welded to the sheet metal 1. When the adjusting nut 10 is movably connected in the adjusting mechanism 3, the adjusting mechanism 3 can be installed in the mounting base 2 (from Figure 2 The bottom of the mounting base 2 is inserted for assembly). During the installation process, if there is an error or tolerance, the adjustment guide column 30 can drive the adjustment screw 4 to move in the Y direction to adjust the Y error; the adjustment screw 4 can also move in the X and Z planes to adjust the error in the XZ plane direction, thereby ensuring the positioning accuracy and assembly efficiency of the hidden handle and door panel. In addition, this embodiment also forms a snap-on strip 300 at the top of the adjustment guide column 30, such as Figures 1 to 4 As shown, when the adjusting guide column 30 drives the snap bar 300 to move from the bottom of the mounting base 2 to the Figure 1 In the state shown, as the adjusting guide post 30 drives the adjusting screw 4 to move in the Y direction along its axis, the spring buckle strip 300 can be movably pressed against the guide member 20, thereby limiting the displacement of the adjusting guide post 30 when driving the adjusting screw 4 toward the sheet metal part 1. If the adjusting guide post 30 is continuously exerted with a force to move the adjusting screw 4 toward the outside of the mounting base 2 (i.e., along the axis), the spring buckle strip 300 can be movably pressed against the guide member 20, thereby limiting the displacement of the adjusting screw 4 when the adjusting guide post 30 drives the adjusting screw 4 toward the sheet metal part 1. Figure 1The spring buckle strip 300 is inevitably squeezed by the guide part 20 and squeezed and deformed into the inside of the adjusting guide column 30, so that the adjusting guide column 30 can drive the adjusting screw 4 (that is, the entire adjusting mechanism 3) to be removed from the mounting base 2. It can be seen that the tolerance adjuster ensures the straightness and stability during the adjustment process through the precise cooperation between the guide part 20 and the adjusting guide column 30, thereby improving the accuracy of spatial position adjustment; the design of the spring buckle strip 300 not only plays a limiting effect during tolerance adjustment, but also can use its own elastic deformation to provide great convenience for the disassembly and assembly of the adjusting mechanism 3 and the adjusting screw 4 relative to the mounting base 2, making installation and maintenance more convenient and reducing maintenance costs.

[0034] The outer wall of the snap-fastener strip 300 is protruded outward to form an extension portion 300 a . The bottom wall of the extension portion 300 a is provided with a guide slope 300 b . The guide slope 300 b is movably pressed against the guide member 20 .

[0035] like Figure 1 、 Figure 3 as well as Figure 4 As shown, the snap-fastener strips 300 in this embodiment can be distributed in a ring shape with multiple strips (two symmetrical strips are used in this solution), wherein the guide slope 300b is formed at the bottom of the extension portion 300a, and the guide column 30 is adjusted along the Figure 1 During downward movement, the extension 300a on the snap-fastener strip 300 first contacts the guide member 20, thereby limiting the displacement of the adjustment guide post 30. As the adjustment guide post 30 continues to move downward, the design of the guiding slope 300b causes the snap-fastener strip 300 to gradually deform (rather than suddenly jamming) when subjected to pressure. This gradual deformation reduces friction during the movement of the adjustment guide post 30, effectively improving the smoothness of the elastic deformation of the extension 300a into the interior of the adjustment guide post 30. It also allows the extension 300a to disengage from the guide portion, allowing the adjustment guide post 30 to drive the adjustment screw 4 to be removed from the mounting base 2. This overall structure is relatively simple, ensuring the stability and reliability of the adjustment guide post 30 during adjustment, while also providing convenience during the disassembly and assembly of the adjustment mechanism 3 and the adjustment screw 4.

[0036] Preferably, if Figure 3 and Figure 4As shown, the spring buckle strip 300 and the adjustment guide column 30 in this embodiment jointly form an L-shaped clearance groove 300c. During the adjustment of the adjustment guide column 30, as the above-mentioned extension portion 300a abuts against the guide portion, the L-shaped clearance groove 300c can provide the entire spring buckle strip 300 with a certain deformation space, thereby avoiding damage to the extension portion 300a and the spring buckle strip 300 due to rigid contact; similarly, when the spring buckle strip 300 is squeezed and deformed toward the inside of the adjustment guide column 30 due to the guide inclined surface 300b abutting against the guide member 20, the L-shaped clearance groove 300c can also ensure the free movement of the spring buckle strip 300 and the extension portion 300a, providing additional stability while effectively preventing the adjustment guide column 30 from tilting or getting stuck during movement.

[0037] The guide member 20 is provided with first spiral guide ribs 21 distributed in an annular manner. The outer wall of the adjustment guide column 30 is formed with second spiral guide ribs 301 . The second spiral guide ribs 301 are movably connected to the first spiral guide ribs 21 .

[0038] like Figure 1 、 Figure 3 and Figure 4 As shown, it should be noted that the first spiral guide rib 21 and the second spiral guide rib 301 in this embodiment are not limited to one group, but can also be two groups, three groups, four groups, five groups, etc., according to the space allowed; after a number of spiral guide ribs are processed and formed according to the preset spacing, the adjustment guide column 30 can rely on the spiral cooperation between the first spiral guide rib 21 and the second spiral guide rib 301 to drive the adjustment screw 4 to adjust the Y-direction tolerance. The overall operation is simple, and it also provides a guarantee for the positioning accuracy of the adjustment screw 4.

[0039] It should be added that, in this embodiment, the distance between the two extensions 300a is slightly larger than the distance between the two first spiral guide ribs 21, so that the adjustment guide column 30 can achieve the required limiting function by relying on the extension 300a to abut against the first spiral guide rib 21 during the adjustment process.

[0040] The adjustment mechanism 3 also includes a centering block 31, which is movably engaged in the adjustment guide column 30 and forms a guide cavity 310 together with the centering block 31. A tightening portion 40 is formed on the adjustment screw 4, and the tightening portion 40 is movably arranged in the guide cavity 310 to allow the adjustment screw 4 to move relative to the adjustment guide column 30 along its radial direction.

[0041] like Figure 1 As shown, when the XZ error needs to be adjusted, the adjusting screw 4 can be moved along the guide cavity 310 by relying on the movement of the pressing portion 40. Figure 1The guide cavity 310 is designed to limit the movement of the adjusting screw 4 in the Y direction, thereby effectively preventing the adjusting screw 4 from shaking or tilting and affecting the accuracy requirement when adjusting the tolerance; on the other hand, it effectively guides the accuracy and reliability of the adjusting screw 4 when adjusting the error in the XZ plane direction.

[0042] Positioning blocks 311 are symmetrically provided at the periphery of the centering block 31 , and a snap-fitting groove 311 a is formed in the positioning block 311 . A snap-fitting block 302 is formed on the inner wall of the adjustment guide column 30 , and the snap-fitting block 302 is movably snap-fitted in the snap-fitting groove 311 a .

[0043] For installation and removal of the centering block 31, refer to Figure 1 、 Figure 4 and Figure 5 As shown, a snap-fit ​​groove 311a is formed in the middle position of each positioning block 311. During the installation process, the snap-fit ​​block 302 is movably inserted into the snap-fit ​​groove 311a, thereby ensuring the stable position of the centering block 31 in the adjustment guide column 30, enhancing the stability of the entire adjustment mechanism 3, and also providing a guarantee for the accuracy and stability of the tightening portion 40 guiding the adjustment screw 4 in the guide cavity 310 to adjust the error in the XZ plane direction.

[0044] The adjusting guide column 30 is further provided with an avoidance groove 303 , and the engaging block 302 can be squeezed and deformed along the avoidance groove 303 when the positioning block 311 is movably pressed against it, and can be movably engaged in the engaging groove 311 a aligned with it due to elastic deformation.

[0045] Preferably, the locking block 302 in this embodiment is close to the opening of the avoidance groove 303. During the installation process, the centering block 31 can be gradually inserted into the adjustment guide column 30. As the positioning block 311 on the centering block 31 applies a certain extrusion force to the locking block 302, the locking block 302 can be squeezed and deformed into the avoidance groove 303, effectively avoiding the locking block 302 from being stuck or damaged due to rigid contact; after the centering block 31 is accurately assembled to the specified position, the locking groove 311a on the positioning block 311 is exactly aligned with the locking block 302, and the locking block 302 relies on its own elastic reset to be movably engaged in the locking groove 311a. It can be seen that the assembly process is relatively simple as a whole, and the operator can easily complete the assembly operation, reducing the difficulty and time of operation, thereby improving work efficiency.

[0046] Preferably, if Figure 5As shown, in this embodiment, arc blocks 312 are symmetrically formed at the periphery of the centering block 31. During the assembly process, the arc blocks 312 are movably pressed against the inner wall of the adjustment guide column 30, and the above-mentioned engagement groove 311a and the engagement block 302 cooperate with each other, thereby further ensuring the stability of the centering block 31 in its position, thereby providing a guarantee for the accuracy of the tolerance adjustment of the adjusting screw 4 in the XZ plane direction.

[0047] Further, if Figure 1 and Figure 3 As shown, in this embodiment, the bottom of the adjusting guide column 30 is formed with a limited position boss 32. It should be noted that in this embodiment, the extension portion 300a on the snap-fastener strip 300 is only for adjusting the guide column 30 in the Figure 1 When the guide post 30 moves downward, it plays a limiting role. During assembly or use, the limiting boss 32 formed at the bottom of the adjusting guide post 30 is movable against the sheet metal part 1, thereby adjusting the guide post 30 in the Figure 1 The same limiting effect is achieved when moving upward, effectively ensuring the smoothness and stability of the adjustment guide post 30 during the entire Y-direction tolerance adjustment.

[0048] Preferably, in this embodiment, the outer diameter of the limiting boss 32 is larger than the inner diameter of the first spiral guide rib 21 and smaller than the inner diameter of the mounting base 2. For this reason, the first spiral guide rib 21 cooperates with the limiting boss 32 to effectively limit the adjustment guide column 30 in the Figure 1 The maximum Y-axis movement distance shown further improves the smoothness and stability of the entire adjustment process.

[0049] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one such feature.
