Description

A concealed door handle tolerance adjuster Technical Field

[0001] This application relates to the field of automotive parts manufacturing technology, and in particular to a hidden door handle tolerance adjuster. Background Technology

[0002] Currently, there are tolerances in the assembly of vehicle concealed door handles with the door sheet metal, including dimensional tolerances and assembly tolerances. Dimensional tolerances are caused by factors such as the manufacturing process of the plastic handle and the position of the welding nuts on the door sheet metal. Assembly tolerances are caused by errors in the deformation of the door handle base and radius during the tightening of the nuts. To achieve a good fit between the surface shape of the concealed door handle and the door sheet metal surface, tolerance adjusters are needed to adjust the tolerances in the X / Y / Z directions of the handle, ensuring the aesthetic appearance of the vehicle handle.

[0003] Existing tolerance adjusters can only adjust linear tolerances in the X / Y / Z directions, and cannot adjust the angular tolerance between the door sheet metal surface and the handle base fixing surface. They can only be forcibly tightened with screws to deform the handle and the door sheet metal, so that the mounting surfaces fit together and achieve the assembly effect. This kind of pre-stressed fit cannot be maintained for a long time. Due to factors such as vibration during vehicle operation, the originally adjusted dimensional tolerances will gradually become invalid, resulting in abnormal noise and looseness of the handle. There is room for improvement. Summary of the Invention

[0004] In order to facilitate the adjustment of the angular tolerance between the door sheet metal and the handle base fixing surface and improve the connection stability between the sheet metal surface and the handle, this application provides a hidden door handle tolerance adjuster.

[0005] This application provides a hidden door handle tolerance adjuster, which adopts the following technical solution:

[0006] A concealed door handle tolerance adjuster, comprising,

[0007] Component B, wherein component B is disposed on the side wall of the door sheet metal;

[0008] Original component A, wherein original component A is disposed on the side of original component B that is away from the door sheet metal;

[0009] A base, wherein the base is threadedly connected to the outer wall of the original component A;

[0010] A locking component passes through component A and component B, and is threadedly connected to the door sheet metal. Both component B and the locking component are in spherical contact with component A, and both component A and component B are in clearance fit with the locking component.

[0011] A positioning element is disposed on the base and is used to connect the base and the original component B.

[0012] By adopting the above technical solution, when installing the hidden door handle, both component A and component B are assembled on the base. The door handle is fixed to the base by injection molding. During the installation of the door handle onto the vehicle body, the tolerance adjuster is installed on the vehicle body. During the locking process of component A and component B, the clearance fit between component A and component B achieves X / Z direction adjustment. Due to the spherical contact between component A and component B, the Y direction angle adjustment is achieved. The spherical contact between component A and component B allows the locking component to achieve adaptive angle adjustment in the locking direction. This eliminates prestress and makes operation more convenient. It also makes the adjustment of the angle tolerance between the door sheet metal and the fixed surface of the handle base more convenient, reducing the possibility of the handle making noise or loosening due to prestress and vehicle body vibration.

[0013] Optionally, a plurality of limiting plates are fixed on the inner wall of the original component A, and a gasket is sleeved on the outer wall of the locking component. The gasket is in spherical contact with the original component A, and the end of the limiting plate abuts against the outer wall of the locking component.

[0014] By adopting the above technical solution, before assembling the tolerance adjuster, the position of the limiting plate is adjusted according to the required tightness of the locking component. After adjusting the position of the limiting plate, the locking component is fixed to the door sheet metal and the vehicle body. When the tolerance adjuster is fixed to the vehicle body, the tip of the locking plate abuts against the side wall of the locking component. The limiting plate limits the position of the locking component, reducing the possibility of the locking component loosening and preventing the locking component from detaching from the original A and original B.

[0015] Optionally, the positioning component includes a plurality of positioning rods fixed on the side wall of the base and a plurality of buckles fixed on the side wall of the original component B. The buckles are arranged in a one-to-one correspondence with the positioning rods, and the positioning rods are engaged and fixed with the inner wall of the corresponding buckles.

[0016] By adopting the above technical solution, after the tolerance adjuster is installed on the vehicle body, the positioning rod is located in the buckle. Under the limitation of the positioning rod and the buckle, the relative position of the base and the original part B is limited, thereby making the structure of the tolerance adjuster more compact, reducing the possibility of the base detaching from the original part B. In addition, during the installation of the tolerance adjuster, the positioning rod guides the movement of the buckle, making it easier to move the relative position of the base and the original part B.

[0017] Optionally, the inner wall of the base is fixed with a boss, and the outer wall of the component A is provided with a groove. The boss and the groove cooperate to realize the spiral rise of the base.

[0018] By adopting the above technical solution, the base is rotated during the locking process, and the boss slides in the groove, fixing the base and the original part A on the original part B. The setting of the boss and the groove is similar to the setting of the thread between the base and the original part A. Since the width of the boss is large, after the base and the original part A are fixed on the original part B, the boss plays a positioning role, thereby making the fixing of the base and the original part A more stable.

[0019] Optionally, a first guide groove is formed through the side wall of component A, and a second guide groove is formed through the side wall of component B. A first driving sleeve is slidably connected to the outer wall of the locking component. A first driving block is fixed to the outer wall of the first driving sleeve. The first driving block can be adapted to the first guide groove. A second driving sleeve is threadedly connected to the outer wall of the locking component. A second driving block is fixed to the outer wall of the second driving sleeve. The second driving block is adapted to the second guide groove. A linkage component for driving the first driving sleeve and the second driving sleeve to slide is provided on the base. The first driving sleeve and the second driving sleeve are keyed together. The moving speeds of the first driving sleeve and the second driving sleeve are not equal.

[0020] By adopting the above technical solution, when assembling the door handle and adjusting the relative positions of component A, component B, and the locking component, the locking component is inserted into component A and component B. The linkage assembly is activated, causing the first and second driving sleeves to slide, so that the first driving block first engages in the first guide groove. At this point, the locking component is turned, causing the locking component to move the first driving block. The first driving block causes component A to shift, moving component A to a suitable position. Continuing to rotate the locking component, the first driving block slides out of the first guide groove, and the second driving block moves, moving into the second guide groove. Turning the locking component again causes the locking component to move the second driving block, which in turn causes component B to undergo a minor adjustment, facilitating the adjustment of the relative positions of components A and B. After completing the relative positioning of components A and B, the locking component is rotated to fix it to the door panel. Under the positioning of the locking component, the door handle is fixed to the vehicle body.

[0021] Optionally, a limiting hole is provided on the side wall of the locking member, and the linkage component includes an adjusting rod and a shaping piece that can engage with the limiting hole. The shaping piece is located between the gasket and the original part A, and the first driving sleeve is key-connected to the shaping piece.

[0022] By adopting the above technical solution, the adjusting plate serves a supporting function. The operator inserts the end of the adjusting rod into the limiting hole, and by rotating and moving the adjusting rod, drives the locking component to move, thereby adjusting the positions of component A and component B. The shaping plate makes the sliding of the first and second driving sleeves smoother and also serves a limiting and fixing function, making the connection between component A and component B more stable.

[0023] Optionally, a first limiting member is threadedly connected to component A, the first limiting member is slidably connected to component B, a second limiting member is threadedly connected to component B, and a sliding groove is provided on the side wall of the sheet metal, the first limiting member passes through the corresponding sliding groove, and the second limiting member passes through the corresponding sliding groove.

[0024] By adopting the above technical solution, after adjusting component A to a suitable position, the position of component A is restricted by the first limiting component to fix component A. Then, component B is adjusted. After adjusting the position of component B, the position of component B is restricted by the second limiting component. Under the restriction of the first and second limiting components, the fixation of component A and component B is more stable.

[0025] Optionally, the shaping piece is in contact with the spherical surface of the original component A, and the shaping piece is in contact with the spherical surface of the gasket.

[0026] By adopting the above technical solution, the contact between the shaping piece and the original A is made closer, and the interference caused during the adjustment of the original A is reduced.

[0027] Optionally, the buckle includes a first positioning frame hinged to the original component B and a second positioning frame hinged to the original component B. A rotating block is fixed at one end of the first positioning frame and the second positioning frame near the original component B. The rotating block is rotatably connected to the original component B. The side wall of the rotating block can abut against the side wall of the original component A. The original component A drives the first positioning frame and the second positioning frame to move closer to each other.

[0028] By adopting the above technical solution, when the locking part is in the loose state, the first positioning frame and the second positioning frame can rotate, which facilitates the separation of the positioning rod from the original part B; when the locking part is locked and the original part A and the original part B are squeezed together, the side wall of the original part A drives the rotating block to rotate, and the first positioning frame and the second positioning frame move closer to each other. At this time, the positioning rod is located between the corresponding first rotating frame and the second rotating frame, which plays a limiting role and facilitates the connection and separation of the limiting rod from the original part B.

[0029] Optionally, the limiting piece has a reinforcing groove on the side facing the original component B, and the reinforcing groove is located in the middle of the limiting piece.

[0030] By adopting the above technical solution, after the locking part is fixed on the tolerance adjuster, the end of the limiting piece abuts against the outer wall of the locking part. During the tightening process of the locking part, the locking part first causes the limiting piece to bend. The opening of the reinforcing groove enhances the strength of the limiting piece, and the positioning of the locking part by the limiting piece is more stable, reducing the possibility of the locking part loosening.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. After the tolerance adjuster is installed on the vehicle body, the spherical contact between component A and component B enables Y-axis angle adjustment; the clearance fit between component A and component B enables X / Z-axis adjustment, facilitating door handle adjustment. The spherical design of component A and component B allows the locking component to achieve adaptive angle adjustment, eliminating prestress and making operation more convenient.

[0033] 2. The setting of the limit plate positions the locking component, reducing the possibility of the locking component loosening during the shaking of the car.

[0034] 3. The first drive block facilitates the adjustment of the relative position of component A, and the second drive block facilitates the adjustment of the relative position of component B, reducing the possibility that component A or component B may be misaligned during the adjustment of component A and component B by locking components.

[0041] The present application will be further described in detail below with reference to Figures 1-5.

[0042] This application discloses a hidden door handle tolerance adjuster.

[0043] Example 1

[0044] Referring to Figure 1, a hidden door handle tolerance adjuster includes component A2 and component B1. Component A2 is hollow. A door sheet metal 20 is provided on the side of component B1 opposite to component A2. A locking component 4 is provided on component A2 to fix component A2 and component B1 to the side wall of the door sheet metal 20. In this application, the locking component 4 is preferably a bolt. A nut is welded and fixed on the side of the door sheet metal 20 opposite to component B1. Component B1 is fitted onto the outer wall of component A2. The locking component 4 is inserted through component A2 and component B1. The locking component 4 is threadedly connected to the nut on the side wall of the door sheet metal 20. Under the constraint of the locking component 4 and the nut, component A2 and component B1 are fixed to the side wall of the door sheet metal 20.

[0045] Referring to Figure 1, the tolerance adjuster also includes a base 3, which is located on the outer wall of the original part A2. A positioning element 5 is provided on the outer wall of the base 3 to limit the position of the base 3 and the original part B1. The positioning element 5 reduces the possibility of the base 3 separating from the original part B1. The positioning element 5 includes several positioning rods 51 integrally injection-molded on the side wall of the base 3 and several latches 52 integrally injection-molded on the side wall of the original part B1. The positioning rods 51 and latches 52 are arranged in a one-to-one correspondence. In this application, three positioning rods 51 are preferably provided. The positioning rods 51 are located within the latches 52, and the relative position of the base 3 and the original part B1 is limited by the snap-fit ​​positioning of the positioning rods 51 and the latches 52.

[0046] Referring to Figure 2, there is a gap between both component A2 and component B1 and the outer wall of locking component 4. A gasket 7 is provided on the bottom wall of component A2 on the side away from the door sheet metal 20. After the locking component 4 is fixed on the door sheet metal 20, the locking component 4 abuts against the side wall of the gasket 7. The gasket 7 is provided to position component A2 and reduce the possibility of the locking component 4 becoming loose.

[0047] Referring to Figure 2, several limiting pieces 6 are integrally formed on the inner wall of the original A2. In this application, two limiting pieces 6 are preferably provided. The limiting pieces 6 are located on the inner wall of the original A2. During the production of the original A2, the tilt angle of the limiting pieces 6 is set according to actual needs. When the worker fixes the locking piece 4, the locking piece 4 first bends the limiting pieces 6. After the locking piece 4 is fixed on the side wall of the door sheet metal 20, the limiting pieces 6 return to the initial state. At this time, the end of the limiting piece 6 abuts against the side wall of the locking piece 4. The limiting pieces 6 position the locking piece 4 and reduce the possibility of the locking piece 4 loosening.

[0048] Referring to Figure 2, a boss 8 is integrally formed on the inner wall of the base 3 by injection molding. The boss 8 is spiral-shaped. A groove 9 is provided on the outer wall of the original part A2. The inner wall of the groove 9 is spiral-shaped. The boss 8 and the groove 9 cooperate. During the rotation of the base 3, the boss 8 slides in the groove 9, causing the base 3 to slide along the height direction of the original part A2, thus fixing the base 3 to the outer wall of the original part A2. The setting of the boss 8 and the groove 9 increases the contact area between the base 3 and the original part A2, and limits the relative position of the base 3 and the original part A2, making the fixing of the base 3 and the original part A2 more stable.

[0049] In the first embodiment of this application, the implementation principle of a hidden door handle tolerance adjuster is as follows: the hidden door handle is integrally injection molded to the side of the base 3 away from the door sheet metal 20. The handle tolerance adjuster is installed on the vehicle body, and the door sheet metal 20 is fixed on the vehicle body. The base 3 is rotated and pressed towards the outer wall of the door sheet metal 20, so that the positions of the original A2 and the original B1 change. After adjusting the position of the hidden door handle, the locking part 4 is fixed on the door sheet metal 20. Since the original A2 and the original B1 are in spherical contact, and the original A2 and the gasket 7 are in spherical contact, adaptive angle adjustment can be achieved during the locking of the locking part 4, eliminating prestress and making operation more convenient.

[0050] Example 2

[0051] Example 2 differs from Example 1 in that: Referring to Figure 3, the buckle 52 includes a first positioning frame 521 and a second positioning frame 522. An installation hole is provided on the side wall of the original component B1. A rotating block 17 is rotatably connected to the inner wall of the installation hole via a rotating shaft. The first positioning frame 521 and the second positioning frame 522 are integrally molded onto the side wall of the corresponding rotating block 17 by injection molding. An elastic element is provided on the inner wall of the installation hole to return the first positioning frame 521 to its original position. In this application, a spring is preferably used as the elastic element. One end of the elastic element is fixedly connected to the side wall of the rotating block 17, and the other end is fixedly connected to the inner wall of the installation hole. When there is a gap between the base 3 and the original component B1... When the base 3 merges with the original B1, one corner of the rotating block 17 is higher than the side wall of the original B1 under the support of the elastic element. During the process of the base 3 merging with the original B1, the base 3 drives the rotating block 17 to rotate, the elastic element is stretched, and the first positioning frame 521 and the second positioning frame 522 approach each other, so that the corresponding positioning rod 51 is located between the first positioning frame 521 and the second positioning frame 522, reducing the possibility of the base 3 separating from the original B1. When it is necessary to separate the base 3 and the original B1, the base 3 moves away from the original B1, and the first positioning frame 521 and the second positioning frame 522 open, which makes it easy for the positioning rod 51 to move out of the first positioning frame 521 and the second positioning frame 522.

[0052] Referring to Figures 4 and 5, the outer wall of the locking member 4 is threaded with a first driving sleeve 41 and a second driving sleeve 42. The second driving sleeve 42 is slidably connected to the first driving sleeve 41. The first driving sleeve 41 and the second driving sleeve 42 are keyed together. The outer wall of the first driving sleeve 41 is integrally formed with a first driving block 411, and the outer wall of the second driving sleeve 42 is integrally formed with a second driving block 421.

[0053] Referring to Figures 3 and 4, the first driving sleeve 41 and the second driving sleeve 42 move at different speeds on the outer wall of the locking member 4. A linkage assembly 12 is provided on the inner wall of the original part A2 to drive the first driving sleeve 41 and the second driving sleeve 42 to move simultaneously. Under the action of the linkage assembly 12, the first driving sleeve 41 and the second driving sleeve 42 move. A limiting hole 13 is provided at the end of the locking member 4. The linkage assembly 12 includes an adjusting rod 131 that can be inserted and fixed into the limiting hole 13 and a shaping piece 132 that is snapped and fixed on the inner wall of the original part A2.

[0054] Referring to Figure 4, a first guide groove 10 is provided on the side wall of component A2, and a second guide groove 11 is provided on the side wall of component B1. Under the drive of the linkage component 12, the second drive sleeve 42 first slides to the position of the second guide groove 11 to adjust the position of component B1. Then, the second drive block 421 slides out of the second guide groove 11, and the first drive block 411 moves into the first guide groove 10. The relative position of component A2 is adjusted by the first drive block 411.

[0055] Referring to Figures 4 and 5, the shaping piece 132 in this application is ring-shaped, and a keyway is provided on the inner wall of the shaping piece 132. A sliding block 19 is welded and fixed on the outer wall of the first driving sleeve 41. The sliding block 19 slides in the keyway, so that the shaping piece 132 is keyed to the first driving sleeve 41. The operator inserts and fixes the adjusting rod 131 in the limiting hole 13, rotates the adjusting rod 131, and the adjusting rod 131 drives the locking member 4 to rotate. Under the support of the shaping piece 132, the first driving sleeve 41 and the second driving sleeve 42 slide along the length direction of the locking member 4, thereby facilitating the adjustment of the relative position of the original A2 and the original B1.

[0056] Referring to Figure 3, the operator moves the adjusting rod 131, which causes the shaping piece 132 to deform, causing the locking piece 4 to swing and the first driving block 411 and the second driving block 421 to move, thereby adjusting the relative position of the original piece A2 and the original piece B1 and reducing the possibility that the original piece A2 and the original piece B1 cannot move and adjust their position due to mutual compression.

[0057] Referring to Figure 4, a second limiting member 15 is threaded onto the original component B1. A sliding groove 16 is provided on the side wall of the door sheet metal 20 near the second limiting member 15. The second limiting member 15 passes through the sliding groove 16. During the adjustment of the relative position of the original component B1, the second limiting member 15 slides along the inner wall of the sliding groove 16. After the original component B1 is adjusted to a suitable position, the second limiting member 15 is locked. The second limiting member 15 restricts the movement of the original component B1, reducing the possibility of the original component B1 moving during the adjustment of the original component A2.

[0058] Referring to Figure 4, a first limiting member 14 is threaded onto component A2. A groove is provided on component B1 near the first limiting member 14. A sliding groove 16 is also provided on the side wall of the door sheet metal 20 near the first limiting member 14. During the adjustment of the position of component A2, the first limiting member 14 slides on component B1 and slides within the sliding groove 16. After the position of component A2 is adjusted, the first limiting member 14 is locked to restrict the movement of component A2.

[0059] Referring to Figure 4, reinforcing grooves 18 are provided on the side walls of the limiting piece 6. The reinforcing grooves 18 are provided along the length of the limiting piece 6 and are located on the side of the limiting piece 6 facing the original part B1. After the end of the limiting piece 6 abuts against the outer wall of the locking member 4, the locking member 4 applies a force to the limiting piece 6 away from the original part B1. The opening of the reinforcing grooves 18 enhances the load-bearing capacity of the limiting piece 6, making the limiting piece 6 more stable in limiting the locking member 4 and reducing the probability of the locking member 4 loosening.

[0060] According to Embodiment 2 of this application, the implementation principle of a hidden door handle tolerance adjuster is as follows: The tolerance adjuster is installed on the vehicle body, one end of the adjusting rod 131 is inserted into the limiting hole 13, the adjusting rod 131 is rotated, the adjusting rod 131 drives the locking member 4 to rotate, causing the first driving sleeve 41 and the second driving sleeve 42 to move, and the second driving block 421 is engaged with the inner wall of the second guide groove 11. At this time, the adjusting rod 131 is swung, causing the locking member 4 to swing, adjusting the position of the original part B1. After the position of the original part B1 is adjusted, the second limiting member 15 is locked to restrict the movement of the original part B1; then the adjusting rod 131 is rotated again, and the second driving block 421 slides out of the second guide groove 11. The guide groove 11, the first drive block 411 slides to the inner wall of the first guide groove 10, the adjusting rod 131 is moved to move the first drive block 411, and the relative position of the original part A2 is adjusted. Then the first limiting member 14 is locked to restrict the movement of the original part A2. Then the adjusting rod 131 is rotated so that the first drive block 411 moves out of the first guide groove 10. The locking member 4 is moved towards the door sheet metal 20 by the adjusting rod 131. The locking member 4 is connected to the side wall of the door sheet metal 20. At this time, the adjusting rod 131 is rotated to lock the locking member 4 on the door sheet metal 20, and the installation of the door handle is completed. Finally, the adjusting rod 131 is removed.

[0061] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
