Description

TECHNICAL FIELD

[0001] The application relates to the technical field of automobile parts, in particular to a handle mounting method. BACKGROUND

[0002] During installation of automobile parts, the installation size and position of the parts will have three axial deviations. In order to adjust the installation deviation of the parts, a tolerance adjuster is usually used. A handle mounting method is disclosed in Chinese patent CN202010948234.4, which uses a tolerance adjuster to realize installation of a handle and a door body. The tolerance adjuster used has a tolerance compensation element, the tolerance compensation element is screwed with the handle through a screw structure, and a through hole larger than the size of the bolt is formed on the tolerance compensation element. In this way, the bolt can move in the X and Z directions within the tolerance compensation element, and at the same time, the tolerance compensation element can rotate in the Y direction relative to the handle, so that the bolt can move in the X, Y and Z directions relative to the handle, thereby realizing tolerance compensation. The tolerance compensation element is installed in the handle, and then the bolt of the tolerance compensation element is locked with the door body, thereby realizing installation of the handle and the door body.

[0003] However, after the handle is assembled to the door body using the above-mentioned tolerance adjuster, the handle cannot be disassembled and reassembled during later maintenance, and therefore there is an urgent need to provide a new tolerance adjuster that can conveniently disassemble and assemble the handle after the handle is assembled to the door body, without affecting later use and maintenance. SUMMARY

[0004] In order to solve the problem that the handle cannot be disassembled or cannot be reassembled after disassembly by the tolerance adjuster in the prior art, the application provides a handle mounting method. The handle is pressed and assembled into the mounting hole of the door body through the elastic clamping piece of the tolerance adjuster, and the handle can be disassembled by loosening the bolt. The handle can be assembled again by tightening the handle and the elastic clamping piece, and the handle can be disassembled and assembled multiple times, and the mounting method is simple and efficient.

[0005] The application provides a handle mounting method. The handle includes a handle body and a tolerance adjuster. The handle body is provided with an assembly hole, and the tolerance adjuster is assembled into the assembly hole. The tolerance adjuster includes a tolerance compensation assembly, a bolt and an elastic clamping piece. The elastic clamping piece is detachably connected to the end of the bolt. The assembly method includes the following steps:

[0006] Step 1: Assemble the tolerance adjuster into the assembly hole of the handle body.

[0007] Step 2: Press the handle body into the mounting hole of the mounting base through the elastic clamping piece of the tolerance adjuster.

[0008] Step 3: Lock the bolt.

[0009] As preferred, the tolerance compensation assembly comprises a screw sleeve and a centering adjuster, an outer wall of the screw sleeve is provided with screw ribs, the screw sleeve is internally provided with a receiving cavity, a bottom wall of the receiving cavity is provided with a through hole, the first end of the bolt extends out of the through hole and is connected with the elastic clamping piece, the size of the through hole is larger than the size of the bolt, and the second end of the bolt is clamped on the bottom wall of the receiving cavity by the centering adjuster.

[0010] As preferred, the elastic clamping piece comprises a main body and a elastic clamping part, a threaded hole is formed in the middle of the main body, the first end of the bolt is screwed with the threaded hole, and the elastic clamping part is elastically clamped with the mounting hole.

[0011] As preferred, the threaded hole is folded to form a flange.

[0012] As preferred, the elastic clamping piece is V-shaped, the main body is plate-shaped, and the elastic clamping part comprises two elastic arms which are formed by converging downward and inward from the edges of the main body.

[0013] As preferred, the elastic arm comprises a first elastic arm which is connected with the main body and extends inward and downward, and a second elastic arm which is connected to the end of the first elastic arm and extends outward and upward.

[0014] As preferred, the elastic clamping part is provided with an abutting part which interferes with the first end of the bolt.

[0015] As preferred, the first elastic arm is provided with an avoiding hole, and the abutting part is arranged on the second elastic arm and extends out of the avoiding hole.

[0016] As preferred, the inner wall of the receiving cavity is provided with a guide rib, and the outer wall of the centering adjuster is provided with a guide groove which cooperates with the guide rib.

[0017] As preferred, the inner wall of the receiving cavity is provided with a clamping groove, the outer wall of the centering adjuster is provided with a first clamping buckle which cooperates with the clamping groove, and / or the inner wall of the centering adjuster is provided with a second clamping buckle which clamps the second end of the bolt on the inner wall of the receiving cavity.

[0018] Compared with the prior art, the application has at least the following technical effects:

[0019] 1. The handle mounting method of the application adopts a tolerance adjuster to mount the handle. The tolerance adjuster is first assembled into the assembly hole of the handle, and then the assembled tolerance adjuster and handle are pressed into the mounting hole of the mounting base through the elastic clamping piece at the end of the tolerance adjuster, and the handle assembly is completed by locking the bolt. The installation process is simple and convenient. When disassembling and maintaining, the handle and the mounting base can be separated by loosening the bolt and the elastic clamping piece. Since the elastic clamping piece remains in the mounting hole, the handle can be reassembled by simply tightening the bolt and the elastic clamping piece when reinstalling the handle. The handle can be easily and efficiently disassembled and assembled multiple times.

[0020] 2. The tolerance compensation element of the tolerance adjuster includes a spiral sleeve and a centering adjuster. The outer side of the spiral sleeve is provided with a spiral rib. The tolerance compensation element can be screwed into the assembly hole of the handle through the spiral rib. The bolt has freedom in the Y-axis direction through the spiral rib on the outer wall of the spiral sleeve. The bolt has freedom in the X-axis and Z-axis directions through the through hole. Since the centering adjuster is arranged in the spiral sleeve, the second end of the bolt can be clamped on the spiral sleeve, avoiding loosening of the bolt during transportation.

[0021] 3. The elastic clamping piece includes a main body and a elastic clamping piece. The main body is provided with a threaded hole. The first end of the bolt is screwed with the threaded hole. When disassembling the handle, the bolt can be loosened to achieve disassembly. In addition, the elastic clamping piece is elastically clamped with the mounting hole. The handle can drive the elastic clamping piece to connect with the mounting hole by pressing the handle, and the handle and the door panel can be quickly installed.

[0022] 4. The edge of the threaded hole is folded to form a flange. The flange lengthens the length of the threaded hole. The flange can limit the bolt to ensure that the bolt will not be offset during tightening. In addition, the presence of the flange can also improve the strength of the threaded hole, avoiding damage to the threaded hole during tightening of the bolt.

[0023] 5. The elastic clamping piece is in the shape of an inverted triangle. The main body is in the shape of a plate. The elastic clamping piece is inwardly retracted from the edge of the main body. When the handle and the mounting base are installed, the inwardly retracted elastic clamping piece can facilitate the entry of the elastic clamping piece into the mounting hole. When the two elastic clamping pieces enter the mounting hole, the distance between the two elastic clamping pieces is reduced by the compression of the mounting hole. When the two elastic clamping pieces return to their original positions after entering the mounting hole, the elastic clamping piece can be prevented from coming out, ensuring the secure installation of the handle and the mounting base.

[0024] 6. The elastic clamping piece includes a first elastic clamping piece and a second elastic clamping piece. The second elastic clamping piece extends outwardly to prevent the elastic clamping piece from coming out of the mounting hole, ensuring reliable installation of the handle and the mounting base.

[0025] 7. The elastic clamping piece is provided with an abutting portion interfering with the first end of the bolt. Since the first end of the bolt interferes with the abutting portion, the bolt will extrude the abutting portion when the bolt is tightened, causing the elastic clamping piece to deform and further preventing the elastic clamping piece from coming out of the mounting hole.

[0026] 8. The first elastic arm is provided with a clearance hole, and the second elastic arm is provided with an abutment part. The abutment part extends out of the clearance hole. During the tightening of the bolt, the bolt is squeezed against the abutment part, and the abutment part drives the second elastic arm to expand outward so that the elastic snap-fit ​​part is locked with the mounting hole of the mounting base.

[0027] 9. The inner walls of the accommodating cavity of the centering adjuster and the screw sleeve are connected by guide ribs and guide grooves. This design allows the centering adjuster to be smoothly installed into the screw sleeve, improving the assembly convenience of the tolerance adjuster.

[0028] 10. The centering adjuster and the inner wall of the receiving cavity of the screw sleeve are engaged by the first buckle and the first slot to prevent the centering adjuster from coming off during transportation, thus improving the reliability of the tolerance adjuster. The inner wall of the centering adjuster is provided with a second buckle, which clamps the second end of the bolt to the inner wall of the receiving cavity. With this configuration, the centering adjuster can limit the bolt to the center of the screw sleeve and prevent the bolt from coming off the screw sleeve during transportation.

The mounting process is simple and convenient, and when disassembling and repairing, the handle 1 and the mounting base 2 can be separated only by loosening the bolt 33 and the elastic clamping piece 31. Since the elastic clamping piece 31 remains in the mounting hole 21, when reinstalling the handle 1, the handle 1 can be reassembled only by tightening the bolt 33 and the elastic clamping piece 31, so that the handle 1 can be disassembled and assembled multiple times simply and efficiently.

[0045] The tolerance compensation element of the tolerance adjuster 3 of the present application includes a spiral sleeve 32 and a centering adjuster 34, the outer wall of the spiral sleeve 32 is provided with a spiral rib 322, the spiral sleeve 32 is provided with a containing cavity 30, the bottom wall of the containing cavity 30 is provided with a through hole 35, the size of the through hole 35 is larger than the size of the bolt 33, the first end of the bolt 33 extends out of the through hole 35 and is clamped with the elastic clamping piece 31, and the second end of the bolt 33 is clamped on the bottom wall of the containing cavity 30 by the centering adjuster 34. The spiral rib 322 on the outer wall of the spiral sleeve 32 can realize the freedom of the bolt 33 in the Y-axis direction, and the through hole 35 can realize the freedom of the bolt 33 in the X-axis and Z-axis directions. Since the spiral sleeve 32 is provided with the centering adjuster 34, the second end of the bolt 33 can be clamped on the spiral sleeve 32 by the centering adjuster 34, so that the bolt 33 is prevented from loosening during transportation.

[0046] In the present application, the spiral sleeve 32 is a cylindrical structure with an open upper end, and a spiral structure is arranged on the outer wall of the spiral sleeve 32. Specifically, the spiral structure is a spiral rib 322, and the installation of the tolerance adjuster 3 and the handle 1 can be achieved by screwing the spiral rib 322 with the assembly hole of the handle 1. Due to the presence of the spiral rib 322, the spiral sleeve 32 can rotate relative to the handle 1 in the Y-axis direction, so that the bolt 33 has a degree of freedom in the Y-axis direction.

[0047] It can be understood that the spiral sleeve 32 of the tolerance adjuster 3 and the centering adjuster 34 are made of plastic material, and the bolt 33 and the elastic clamping piece 31 are made of metal material.

[0048] It can be understood that the elastic clamping piece 31 and the first end of the bolt 33 are detachably connected, which can be clamped or screwed, and the specific disassembly method is not limited. In the present application, the elastic clamping piece 31 has a main body part 313 and a elastic clamping part, a threaded hole is formed in the middle of the main body part 313, the first end of the bolt 33 is screwed with the threaded hole, and the elastic clamping part is elastically clamped with the mounting hole 21 of the mounting base 2. The bolt 33 and the elastic clamping piece 31 are screwed through the threaded hole, and when the handle 1 is disassembled, only the bolt 33 needs to be rotated to separate the handle 1 from the mounting base 2.

[0049] Specifically, the elastic clamping piece 31 of the present application is in the shape of an inverted triangle, the main body part 313 of the elastic clamping piece 31 is in the shape of a flat plate, and the elastic clamping part is in the shape of two elastic arms formed by inwardly and downwardly contracting from the edge of the main body part 313. When the handle 1 is installed with the mounting base 2, the inwardly and downwardly contracting elastic arms can facilitate the elastic clamping piece 31 to enter the mounting hole 21, and when the two elastic arms enter the mounting hole 21, the distance between the two elastic arms is compressed by the mounting hole 21 to reduce, and when entering the mounting hole 21, the two elastic arms return to the original position to avoid the elastic clamping piece 31 from coming out, thereby ensuring the firm installation of the handle 1 and the mounting base 2.

[0050] Further, the elastic arm includes a first elastic arm 311 connected with the main body part 313 and extending downwardly and inwardly, and a second elastic arm 312 connected at the end of the first elastic arm 311 and extending upwardly and outwardly. The outward extension of the second elastic arm 312 can prevent the elastic clamping piece 31 from coming out of the mounting hole 21, thereby ensuring the reliable installation of the handle 1 and the mounting base 2. In addition, the second elastic arm 312 can prevent the elastic clamping piece 31 from coming out of the mounting hole 21 of the mounting base 2 when the bolt 33 is unscrewed, thereby providing a basis for the reassembly of the handle 1.

[0051] Further, the elastic buckle part is provided with an abutting part 3121 interfering with the first end of the bolt 33, when the elastic clamping part 31 is pressed into the mounting hole 21 of the mounting base 2, the reliable assembly of the handle 1 and the mounting base 2 can be realized by tightening the bolt 33, in the process of tightening the bolt 33, the first end of the bolt 33 extrudes the abutting part 3121 to make the elastic buckle part expand, so the arrangement, the bolt 33 will extrude the abutting part 3121 when tightening the bolt 33, and further make the elastic buckle part deform, further avoid the elastic clamping part 31 from the installation hole 21, ensure the stability of the handle 1 installation.

[0052] Preferably, the first elastic arm 311 is provided with an avoiding hole 3111, the abutting part 3121 is arranged on the second elastic arm 312, the abutting part 3121 extends inwardly from the second elastic arm 312 and extends out of the avoiding hole 3111, when the bolt 33 is tightened, the bolt 33 contacts and extrudes the abutting part 3121 to make the abutting part 3121 drive the second elastic arm 312 to expand outwardly, further reduce the possibility of the elastic clamping part 31 from the installation hole 21, improve the firmness of the handle 1 installation.

[0053] In the present application, the accommodation cavity 30 of the spiral sleeve 32 is provided with a centering adjuster 34, the outer wall of the centering adjuster 34 is provided with a guide groove 342, the inner wall of the accommodation cavity 30 is provided with a guide rib 323, in the process of assembling the centering adjuster 34, the guide rib 323 can slide in the guide groove 342, so the arrangement can improve the assembly smoothness of the centering adjuster 34, improve the assembly efficiency of the tolerance adjuster 3.

[0054] In the present application, the inner wall of the accommodation cavity 30 is further provided with a first clamping groove 321, the outer wall of the centering adjuster 34 is provided with a first clamping buckle 341, the cooperation of the first clamping buckle 341 and the first clamping groove 321 can make the centering adjuster 34 reliably assembled into the spiral sleeve 32. At the same time, the inside of the centering adjuster 34 is further provided with a second clamping buckle 343, when the centering adjuster 34 is installed in the spiral sleeve 32 through the first clamping buckle 341 and the first clamping groove 321, the second clamping buckle 343 can extrude the second end of the bolt 33 on the inner wall of the accommodation cavity 30, so the arrangement, the centering adjuster 34 can limit the bolt 33 in the middle part of the bolt 33 sleeve, can effectively avoid the problem that the bolt 33 deviation leads to the damage of the spiral sleeve 32.

[0055] Further, the tolerance adjuster 3 of the present application can also be provided with a metal gasket having a second through hole, the metal gasket being arranged between the centering adjuster 34 and the bottom wall of the accommodating cavity 30, the first end of the bolt 33 extending out of the accommodating cavity 30 through the second through hole and the through hole 35 of the bottom wall of the accommodating cavity 30 in sequence, the second end of the bolt 33 being clamped on the metal gasket by the centering adjuster 34, since the sizes of the second through hole of the metal gasket and the first through hole 35 of the bottom wall of the accommodating cavity 30 are the same as that of the bolt 33, the bolt 33 can move in the first through hole 35 and the second through hole, ensuring the freedom of the bolt 33 in the X-axis and Z-axis directions, since the bolt 33 does not directly contact the screw sleeve 32, the torque loss and pre-tightening loss caused by material creep can be effectively avoided, and the handle 1 can be prevented from loosening.

[0056] The installation method of the handle 1 of the present application is as follows: first, the first end of the bolt 33 extends out of the screw sleeve 32 through the through hole 35 of the bottom of the accommodating cavity 30; then, the guide groove 342 of the centering adjuster 34 is aligned with the guide rib 323 in the accommodating cavity 30 and assembled into the accommodating cavity 30, the second end of the bolt 33 is pressed against the bottom wall of the accommodating cavity 30 by the centering adjuster 34; subsequently, the elastic clamping piece 31 is screwed on the first end of the bolt 33 through the threaded hole; the assembly of the tolerance adjuster 3 can be completed through the above steps; the assembled tolerance adjuster 3 is screwed into the assembly hole of the handle 1 through the spiral ribs 322 on the outer side of the screw sleeve 32, and the tolerance adjuster 3 and the handle 1 are assembled into one body; subsequently, the assembled handle 1 is pressed onto the mounting base 2, and in the pressing process, the elastic arms of the elastic clamping piece 31 are deformed by being extruded by the mounting hole 21, so that the elastic clamping piece 31 can be extruded into the mounting hole 21, and when installed in place, the elastic arms return to the original position under the action of their own elasticity, so that the elastic clamping piece 31 cannot be pulled out of the mounting hole 21 in the reverse direction; finally, the bolt 33 is tightened, and in the process of tightening the bolt 33, the elastic arms are further expanded outwardly by being extruded by the bolt 33 to prevent the elastic clamping piece 31 from being pulled out.

[0057] The above method can realize the simple assembly of the handle 1 and the mounting base 2, and when the handle 1 needs to be disassembled from the mounting base 2 for maintenance, only the bolt 33 needs to be loosened to realize the disassembly of the handle 1 and the mounting base 2, since the elastic clamping piece 31 is elastically clamped with the mounting hole 21 of the mounting base 2, the elastic clamping piece 31 cannot be pulled out of the mounting hole 21, when the bolt 33 is loosened, the bolt 33 is separated from the elastic clamping piece 31, and the elastic clamping piece 31 is left on the mounting base 2, and when reinstalled, only the bolt 33 and the elastic clamping piece 31 need to be tightened again to realize the reinstallation of the handle 1 and the mounting base 2.

[0058] It can be understood that during the assembly of the handle 1, the tolerance adjuster 3 is generally a pre-assembled component, only needs to be screwed into the assembly hole of the handle 1, and then the assembled handle 1 and the tolerance adjuster 3 are pressed into the mounting hole 21 on the mounting base 2 through the elastic clamping piece 31 to realize the assembly of the handle 1, the assembly process is simple and efficient, and the assembly efficiency of the handle 1 is greatly improved.
