[0002] With the development of society and the improvement of people's living standards, electric vehicles have become an essential means of transportation for people's daily travel. The hidden door handle is a characteristic product of the intelligence of electric vehicles, and the semi-hidden door handle is also a future trend. Currently, the installation method of the hidden door handle on a vehicle is to fix the hidden door handle to the inner door reinforcement sheet metal from the inner door panel side, and then adjust the clearance difference and surface difference through the tolerance regulator body.

[0003] Existing regulators are generally large in size, and the torque generated during installation may cause the regulator to track and follow, resulting in sheet metal deformation or misalignment of the door handle clearance, affecting the installation quality of the hidden door handle. Summary of the Invention

[0004] The purpose of the present invention is to provide a new method for assembling a door handle and a corresponding tolerance regulator structure with a simple structure and reasonable design to solve the above problems.

[0029] The following further describes the present application in detail with reference to the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0030] Embodiment

[0031] As Figure 1 - Figure 6 shown, a new door handle assembly method and the corresponding tolerance adjuster structure include a tolerance adjuster main body 4 installed on the automotive door handle 1, the outer door sheet metal 2 of the automotive door, the inner door reinforcement sheet metal 3 and the bolt 5. The door handle 1 is installed on the inner door reinforcement sheet metal 3 through the cooperation of the tolerance adjuster main body 4 and the bolt 5;

[0032] One end of the bolt 5 is provided with a guide tip 52, and a flange 51 is fixedly connected to the end of the bolt 5 away from the guide tip 52. The guide tip 52 is provided on the bolt 5 to facilitate the guiding and positioning of the end of the bolt 5 during the installation process, and the flange 51 is provided for mating and fixing;

[0033] There are handle installation positioning holes 21 on the outer door sheet metal 2, and bolt assembly holes 31 on the inner door reinforcing sheet metal 3. The diameter of the bolt assembly hole 31 is larger than the outer diameter of the bolt thread 53 and smaller than the outer diameter of the flange 51 of the bolt 5. During use, the door handle 1 with the tolerance adjuster body 4 installed is passed through the outer door sheet metal 2 through the handle installation positioning hole 21, and the tolerance adjuster body 4 is aligned with the bolt assembly hole 31 opened on the inner door reinforcing sheet metal 3. Then, the bolt 5 can be passed through the bolt assembly hole 31 and screwed with the tolerance adjuster body 4, and fixed with the cooperation of the flange 51;

[0034] The tolerance adjuster body 4 includes a stud 42. There is a connection structure on the outside of the stud 42 for connecting with the door handle 1. One end of the tolerance adjuster body 4 away from the thread limiting boss 428 forms a connection part 426 for assembling with the door handle 1. The connection structure includes a first spiral structure 421 opened on the outer wall of the connection part 426, and also includes a second spiral structure 11 provided on the door handle 1 and cooperating with the first spiral structure 421, so that the tolerance adjuster body 4 can be fixed with the door handle 1 through the cooperation of the first spiral structure 421 and the second spiral structure 11 provided on the door handle 1;

[0035] There is a stop boss 427 integrally formed with the connection part 426 at the end of the first spiral structure 421 opened on the connection part 426, which is used to limit the tolerance adjuster body 4 through the stop boss 427;

[0036] There are a bolt through-hole 423 and a stud boss 422 inside the stud 42. There is an inner cavity 425 opened in the stud 42 above the stud boss 422. A nut 41 adapted to the size of the inner cavity 425 is arranged in the inner cavity 425. The nut 41 is preferably a non-circular structure. An internal hole thread 411 cooperating with the bolt thread 53 opened on the bolt 5 is opened on the inner side wall of the nut 41. After the guiding tip 52 of the bolt 5 passes through the bolt assembly hole 31, the bolt 5 can be screwed with the nut 41 through the cooperation of the bolt thread 53 and the internal hole thread 411;

[0037] There is a thread limiting boss 428 at the initial end of the thread of the stud 42. There are a plurality of process holes 429 distributed in a ring on the contact surface between the stud 42 and the inner door reinforcing sheet metal 3. There is a limiting boss 424 for limiting the nut 41 arranged in the upper part of the inner cavity 425 of the stud 42, which can limit the position of the nut 41 through the limiting boss 424, and try to avoid the problem that the nut 41 rotates synchronously during the process of screwing the bolt 5, resulting in the inability to screw the bolt 5 tightly;

[0038] The aperture of the bolt assembly hole 31 formed in the inner door reinforcing sheet metal 3 is equal to the diameter of the bolt thread 53 plus the adjustment amount, and the diameter of the flange 51 is greater than the diameter of the bolt assembly hole 31 plus the adjustment amount. Thus, the tolerance adjuster body 4 is connected to the inner door reinforcing sheet metal 3 through the cooperation of the bolt assembly hole 31, the bolt 5, and the flange 51.

[0039] As Figure 7 shown, an assembly method for the structure of a door handle tolerance adjuster, based on a novel structure of a door handle tolerance adjuster according to any one of claims 1-7, specifically includes the following steps:

[0040] Step 1: Pass the door handle with the attached tolerance adjuster body 4 through the handle installation positioning hole 21 formed in the outer door sheet metal 2 from the outside of the car door.

[0041] Step 2: Adjust the position of the door handle so that the edge position of the door handle fits and positions with the inner wall of the handle installation positioning hole 21.

[0042] Step 3: Align the end of the tolerance adjuster body 4 with the internal thread 411 of the inner hole with the bolt assembly hole 31.

[0043] Step 4: Pass the bolt 5 through the bolt assembly hole 31 and thread it with the nut 41.

[0044] Step 5: Tighten the bolt 5 to drive the automatic rotation of the tolerance adjuster body 4 and position it on the inner door reinforcing sheet metal 3.

[0045] It should be noted that for this novel door handle assembly method and the corresponding tolerance adjuster structure, during use, the tolerance adjuster body 4 is connected to the second spiral structure 11 provided on the door handle 1 through the first spiral structure 421 formed in the connecting portion 426. Then, the door handle 1 with the attached tolerance adjuster body 4 is passed through the handle installation positioning hole 21 formed in the outer door sheet metal 2 from the outside of the car door, and the edge position of the door handle 1 is fitted with the handle installation positioning hole 21 to position the door handle 1. At this time, the end of the tolerance adjuster body 4 with the internal thread 411 of the inner hole is exactly aligned with the bolt assembly hole 31 formed in the inner door reinforcing sheet metal 3. The user can then pass the bolt 5 through the bolt assembly hole 31 from the inside of the inner door reinforcing sheet metal 3 and thread it with the nut 41 installed in the inner cavity 425 of the tolerance adjuster body 4. At this time, by tightening the bolt 5, the automatic rotation of the tolerance adjuster body 4 is driven to position it on the inner door reinforcing sheet metal 3. By tightening the bolt 5, the inner door reinforcing sheet metal 3 and the tolerance adjuster body 4 can be locked.

[0046] The above-described embodiments merely represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention.
