[0002] With the rapid development of the automobile industry, the contours of automobile door panels have become more diverse, the requirements for the installation and alignment of automobile door handles have become higher and higher, and the handle styles have become more diverse; the door handles are connected to the counterparts on the door sheet metal through an assembly structure, and the door handles are required to ensure that the handles (handles) can be accurately aligned with the handle holes on the door during installation. Because there may be certain errors in the counterparts on the door sheet metal, there is a deviation between the handles and the handle holes when the door handles are fixed on the door panel, which makes the alignment of the door handles more difficult during assembly.

[0003] At present, a plurality of connecting brackets are arranged around the base of the door handle. The connecting brackets are generally connected to the connecting holes on the door panel by bolts. Since there may be deviations between the positions of the bolts and the connecting holes, some existing connecting brackets have adjustable functions to absorb dimensional errors. However, their structures are relatively complex and inconvenient to assemble. Utility Model Content

DETAILED DESCRIPTION

[0024] 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.

[0025] like Figure 1-4 As shown, an adjustable connecting bracket includes: a bracket seat 100, the bracket seat 100 is provided with a threaded hole 110, and the inner wall surface of the threaded hole 110 has an internal thread 120; an adjusting nut 200, the adjusting nut 200 is installed in the threaded hole 110, the outer peripheral surface of the adjusting nut 200 has an external thread 210, the internal thread 120 is connected to the external thread 210, and the adjusting nut 200 moves along the axial direction of the threaded hole 110 when the adjusting nut 200 rotates; an elastic support sleeve 300, the elastic support sleeve 300 is fixedly connected to the adjusting nut 200, and the elastic support sleeve 300 has a through hole 330; a bolt 400, the bolt 400 is penetrated through the through hole 330 and is in contact with the elastic support sleeve 300, and the elastic support sleeve 300 is configured to allow the bolt 400 to move in the radial direction of the through hole 330 through its own deformation.

[0026] The bracket seat 100 is the basic part of the entire bracket. The adjusting nut 200 is placed in the threaded hole 110 of the bracket seat 100. When the adjusting nut 200 rotates, it moves along the axial direction of the threaded hole 110. This action enables the adjusting nut 200 to be fine-tuned along the Z axis to adapt to errors of different sizes. The elastic support sleeve 300 is a key component, which is fixedly connected to the adjusting nut 200 and has a built-in through hole 330. The elastic support sleeve 300 not only provides the necessary support for the bolt 400, but also allows the bolt 400 to move with a certain degree of freedom in its radial direction (i.e., XY plane) through its own elastic deformation ability, thereby absorbing the dimensional errors in the X and Y directions. The bolt 400 passes through the through hole 330 of the elastic support sleeve 300. This design allows the bolt 400 to find the correct alignment position through the adjusting nut 200 and the elastic support sleeve 300 during the installation process, even in the face of slight angles or position deviations, ensuring that the handle is accurately docked with the preset handle hole on the door.

[0027] Preferably, the outer diameter of the bolt 400 is smaller than the inner diameter of the through hole 330, and the elastic support sleeve 300 only presses against the head of the bolt 400 in the axial direction of the bolt 400, which means that the bolt 400 can be adjusted to a certain extent within the range of the through hole 330. When the adjustment range of the bolt 400 in the XY plane exceeds the range of the through hole 330 itself, the elastic support sleeve 300 allows the bolt 400 to be adjusted to a larger extent through its own deformation.

[0028] In summary, this adjustable connecting bracket achieves flexible adjustment in three-dimensional space through the coordinated work of the bolt 400, the elastic support sleeve 300 and the adjusting nut 200, effectively solves the positioning problem caused by manufacturing tolerances or inaccuracies in the assembly process, improves the accuracy and efficiency of the installation of automobile door handles, and also simplifies the assembly process.

[0029] like Figure 1-4 As shown, based on the above embodiment, the elastic support sleeve 300 includes a base portion 310 and a support portion 320, the support portion 320 is flexibly connected to the base portion 310, the base portion 310 is fixedly connected to the adjusting nut 200, and the support portion 320 is in contact with the head of the bolt 400.

[0030] The elastic support sleeve 300 is divided into a base portion 310 and a support portion 320 along its axial direction. The base portion 310 is responsible for rigid connection with the adjustment nut 200 to ensure the stability of the overall structure. The support portion 320 is flexibly connected to the base portion 310. When the adjustment range of the bolt 400 on the X-Y plane exceeds the range of the through hole 330 itself, the support portion 320 deforms relative to the base portion so that the bolt 400 can be adjusted within a larger range.

[0031] It should be further explained here that, in the actual connection structure, the end of the support portion 320 is connected in contact with the head of the bolt 400, and the end of the base portion is connected in contact with the counterpart 500, that is, the front and rear ends of the elastic support sleeve 300 are respectively connected in contact with the head of the bolt 400 and the counterpart 500, thereby limiting the axial freedom of the bolt 400.

[0032] Based on the above embodiment, the adjusting nut 200 is provided with a mounting hole 220 , and the outer peripheral surface of the base 310 has a snap-fitting groove 311 , which is snap-fitted into the edge of the mounting hole 220 to fix the base 310 and the adjusting nut 200 together.

[0033] The adjusting nut 200 itself is provided with a mounting hole 220, which provides a fixed interface for fixing the base 310. The outer peripheral surface of the base 310 is designed with a snap-fitting groove 311, which cleverly snaps with the edge of the mounting hole 220 on the adjusting nut 200 to form a stable connection. This snap-fitting structure not only ensures that the base 310 and the adjusting nut 200 will not loosen easily, but also simplifies the assembly process, and the installation can be quickly completed without complicated tools or additional fasteners.

[0034] like Figure 1-2 As shown, based on the above embodiment, the support portion 320 is configured as a conical sleeve structure, and the end of the support portion 320 is in contact with the head of the bolt 400. The conical design means that one end of the support portion 320 gradually becomes thinner until its end is in close contact with the head of the bolt 400, and the dimensional errors in the X and Y directions can be eliminated through the elastic deformation of the conical structure.

[0035] On the basis of the above embodiment, the elastic support sleeve 300 is a rubber piece or a silicone piece. Both rubber and silicone have good elasticity and can deform under the action of external force and then return to their original state, which is very important for absorbing the dimensional deviation that may exist during the installation process. When the bolt 400 needs to be fine-tuned in the radial direction, the elastic support sleeve 300 can adapt to this movement by its own deformation, thereby ensuring the flexibility and accuracy of the connection.

[0036] like Figure 1-4 As shown, a hidden door handle installation mechanism includes an adjustable connecting bracket and an opponent 500, wherein the opponent 500 is provided with a locking nut 510, the elastic support sleeve 300 is abuttingly connected to the opponent 500, and the bolt 400 is connected to the locking nut 510.

[0037] The connecting bracket can be used for the assembly of hidden door handles and door sheet metal. The door sheet metal has a handle hole and multiple preset positions. When the handle on the handle base is assembled into the handle hole, there may be a certain size error between the connecting bracket and the preset position (locking nut 510). The connecting bracket realizes fine-tuning in three dimensions through a combination of threaded holes 110, adjusting nuts 200, elastic support sleeves 300 and bolts 400 to ensure that the handle is precisely aligned with the preset positions on the door sheet metal.

[0038] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0039] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0040] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
