Description

Technical Field

[0001] This invention belongs to the field of automotive parts technology, and relates to a concealed door handle and a connection structure between the door handle and the door sheet metal. Background Technology

[0002] With the rapid development of the automotive industry, the shape and contour of car door panels have become more and more diverse, and the requirements for the installation and alignment of car door handles have become increasingly stringent, with more diverse handle styles. Car door handles are connected to the mating parts on the car door sheet metal through an assembly structure, and it is required that the door handle (pull handle) be accurately aligned with the handle hole on the car door during installation. Because there may be a certain degree of error in the mating parts on the car door sheet metal, there will be a deviation between the handle and the handle hole when the door handle is fixed to the car door panel, which increases the difficulty of alignment during the assembly of the door handle. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the prior art by proposing a concealed door handle and a connection structure between the door handle and the door sheet metal.

[0004] The objective of this invention can be achieved through the following technical solution: a concealed car door handle, comprising:

[0005] A handle base is provided with at least one support seat, and the support seat is equipped with a deformable connecting bracket. The connecting bracket is in a pre-installed position under its own rigid support. The support seat can move relative to the connecting bracket in either a first direction or a second direction through the elastic deformation of the connecting bracket. The first direction and the second direction are perpendicular to each other in a plane. When the connecting bracket is fixed, the handle base is allowed to move relative to the connecting bracket.

[0006] Preferably, the connecting bracket includes two elastic constraint parts, which are respectively located on both sides of the bracket seat. The bracket seat is in contact with the two elastic constraint parts, and the two elastic constraint parts rigidly bind the connecting bracket and the bracket seat together. The bracket seat can overcome the constraint of the elastic constraint parts and move in the first direction and / or the second direction.

[0007] Preferably, the elastic constraint portion has two deformable first elastic pieces, the two first elastic pieces of one elastic constraint portion abutting against one side profile surface of the bracket seat and the two first elastic pieces of the other elastic constraint portion abutting against the other side profile surface of the bracket seat.

[0008] Preferably, when the support seat moves in the first direction, the two first spring pieces of one of the elastic constraint portions are compressed and deformed by the support seat; when the support seat moves in the second direction, one first spring piece of one elastic constraint portion and one first spring piece of another elastic constraint portion are compressed and deformed by the support seat.

[0009] Preferably, the elastic constraint part further has a deformable second spring piece, which is in contact with one end face of the support base. The support base can overcome the constraint of the second spring piece and move upward in a third direction, which is perpendicular to the plane containing the first direction and the second direction.

[0010] Preferably, the connecting bracket further includes a panel portion, and both elastic constraint portions are fixedly connected to the panel portion, the panel portion being provided with a connecting portion for connecting to sheet metal parts.

[0011] Preferably, the connecting part is configured with at least two expandable latches, one end of which is integrally connected to the panel part, and each of the latches can be expanded to form an expanded state.

[0012] Preferably, it also includes an adjusting nut, wherein the bracket seat has a threaded hole with internal threads, the outer surface of the adjusting nut has external threads, the adjusting nut is movably connected to the threaded hole in the third direction, and the internal threads are connected to the external threads, and the adjusting nut moves in the third direction when it rotates.

[0013] Preferably, the adjusting nut is fitted with a screw that passes through the panel portion and inserts between each of the retaining feet, thereby causing each retaining foot to expand and open, and each retaining foot is threaded by the screw to lock the screw in place.

[0014] A connection structure between a door handle and a car door sheet metal includes: the aforementioned concealed car door handle, and a sheet metal part, the panel of which is in contact with the sheet metal part, the sheet metal part having a through hole, each of the latches extending into the through hole, and each of the latches expanding and opening up locking the through hole, thereby fixing the connecting bracket to the sheet metal part, and allowing the handle base to be slightly adjusted when each of the latches is fixed to the sheet metal part.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. The door handle can be finely adjusted in multiple directions, thereby eliminating size errors and ensuring that the handle on the handle base can be aligned with the handle hole on the door, reducing assembly difficulty and facilitating the installation of the door handle.

[0017] 2. If there is no deviation in the position of the mating parts on the door sheet metal, the connecting bracket will remain in the pre-installation position due to its own rigidity. Therefore, the connecting bracket will directly connect to the mating parts on the door sheet metal, and the handle on the handle base will be aligned with the handle hole on the door, so no adjustment is required. However, if there is a deviation in the position of the mating parts on the door sheet metal, the handle base can be slightly adjusted while the connecting bracket is connected to the mating parts on the door sheet metal, so that the handle on the handle base is aligned with the handle hole on the door. This allows the connecting bracket to be in the pre-installation position under normal circumstances, and also allows the handle base to overcome the elastic constraint of the connecting bracket and move for fine adjustment in the first direction (X-axis) and the second direction (Y-axis), which is very convenient.

[0018] 3. When the handle base moves to the left, the two first spring pieces of the elastic constraint part on the left are squeezed and deformed by the bracket; when the handle base moves to the right, the two first spring pieces of the elastic constraint part on the right are squeezed and deformed by the bracket; when the handle base moves upward, the first spring pieces of the two elastic constraint parts on the upper side are squeezed and deformed by the bracket; when the handle base moves downward, the first spring pieces of the two elastic constraint parts on the lower side are squeezed and deformed by the bracket. It should be noted that when the handle base (bracket) moves in other directions, its direction of movement can be decomposed into components in the first direction and the second direction.

[0019] 4. When the connecting bracket is in the pre-installation position, the four first spring pieces are rigidly connected to the bracket seat, thereby constraining the connecting bracket and the bracket seat together to keep them relatively stationary.

[0020] 5. During installation, since the connecting bracket is connected to the sheet metal part, the bracket seat can move relative to the third direction through the deformation of the second spring, so that the bracket seat is in a suitable position in the Z-axis direction. This results in a certain gap between the bracket seat and the connecting bracket. When the adjusting nut is rotated, it can move towards the panel, so that the adjusting nut and the panel are in contact and connected, eliminating the gap between the bracket seat and the panel in the Z-axis direction.

Detailed Implementation

[0027] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0028] like Figure 1-5 As shown, a concealed door handle includes: a handle base 100, the handle base 100 having at least one bracket 300, the bracket 300 having a deformable connecting bracket 400 mounted thereon, the connecting bracket 400 being in a pre-installed position under its own rigid support, the bracket 300 being able to move relative to the connecting bracket 400 in either a first direction or a second direction through the elastic deformation of the connecting bracket 400, the first direction and the second direction being perpendicular to each other in a plane, and the handle base 100 being allowed to move relative to the connecting bracket 400 when the connecting bracket 400 is fixed.

[0029] The concealed door handle is actually a door handle assembly. The bracket 300 and the connecting bracket 400 constitute the alignment assembly mechanism 200. The handle base 100 has multiple alignment assembly mechanisms 200. When the concealed door handle is installed on the door sheet metal, it needs to be connected to the door sheet metal through the connecting brackets 400 of each alignment assembly mechanism 200. The handle base 100 can move within a certain range to eliminate dimensional errors in various directions during installation and ensure that the handle on the handle base 100 is aligned with the handle hole on the door before it is fixed.

[0030] It should be noted that the first, second, and third directions are the X-axis, Y-axis, and Z-axis, respectively. The bracket base 300 (handle base 100) can be adjusted on the X-axis and Y-axis. The connecting bracket 400 has a certain degree of elasticity, so the bracket base 300 is allowed to move within the maximum elastic deformation range of the connecting bracket 400. That is, the bracket base 300 obtains the space allowance for movement in all directions by deforming the connecting bracket 400. When the connecting bracket 400 is not subjected to external force or is only subjected to its own weight, it remains relatively stationary relative to the bracket base 300 due to its own rigidity. In this state, the connecting bracket 400 is constrained in the pre-installation position, so that the connecting bracket 400 will not move when connected to the door sheet metal fittings, which facilitates the connection between the connecting bracket 400 and the fittings.

[0031] It should be noted that in the existing concealed door handle and door sheet metal, at least two alignment assembly mechanisms 200 need to be set up to connect with the mating parts (through holes 710) on the door sheet metal. However, the position of the mating parts on the door sheet metal may be deviated. This deviation will cause the handle base 100 to fail to align with the handle hole on the door after installation.

[0032] For the reasons mentioned above, the connecting bracket 400 on the concealed door handle is designed as a deformable structure. This means that the bracket base 300 can overcome the elastic constraint of the connecting bracket 400 and move along the X and Y axes. If there is no deviation in the position of the mating part on the door sheet metal, the connecting bracket 400 remains in the pre-installation position due to its own rigidity. The connecting bracket 400 can be directly connected to the mating part on the door sheet metal, and the handle on the handle base 100 is aligned with the handle hole on the door, so no adjustment is required. However, if there is a deviation in the mating part on the door sheet metal, the handle base 100 can be finely adjusted while the connecting bracket 400 is connected to the mating part on the door sheet metal, so that the handle on the handle base 100 is aligned with the handle hole on the door, and then fixed. This allows the connecting bracket 400 to be in the pre-installation position under normal circumstances, and also allows the handle base 100 to overcome the elastic constraint of the connecting bracket 400 and move for fine adjustment in the first direction (X axis) and the second direction (Y axis), which is very convenient.

[0033] like Figure 1-4 As shown, based on the above embodiment, the connecting bracket 400 includes two elastic constraint parts 410. The two elastic constraint parts 410 are respectively located on both sides of the bracket base 300. The bracket base 300 is in contact with the two elastic constraint parts 410. The two elastic constraint parts 410 constrain the connecting bracket 400 and the bracket base 300 together by their own rigidity. The bracket base 300 can overcome the constraint of the elastic constraint parts 410 and move in the first direction and / or the second direction.

[0034] The elastic constraint part 410 has low rigidity and can deform when subjected to external force. Therefore, the elastic constraint part 410 can rely on its own rigidity to support the bracket 300, thereby keeping the connecting bracket 400 in the pre-installation position and preventing the connecting bracket 400 from being misaligned due to movement. Once the bracket 300 is moved by external force, the elastic constraint part 410 can deform to allow the bracket 300 to move. The design of the two elastic constraint parts 410 can just restrain the bracket 300 to move up, down, left, and right (i.e., move in the Y-axis and X-axis directions). When the bracket 300 is subjected to a certain external force, at least one of the two elastic constraint parts 410 is squeezed and deformed, thereby allowing the bracket 300 to move up, down, left, and right.

[0035] Based on the above embodiments, the elastic constraint part 410 has two deformable first elastic pieces 411. The two first elastic pieces 411 of one elastic constraint part 410 are in contact with one side profile surface of the support base 300, and the two first elastic pieces 411 of the other elastic constraint part 410 are in contact with the other side profile surface of the support base 300.

[0036] Based on the above embodiments, when the support base 300 moves in the first direction, the two first spring pieces 411 of one elastic constraint part 410 are squeezed and deformed by the support base 300; when the support base 300 moves in the second direction, one first spring piece 411 of one elastic constraint part 410 and one first spring piece 411 of another elastic constraint part 410 are squeezed and deformed by the support base 300.

[0037] The support base 300 has two degrees of freedom in the first direction (i.e., moving to the left or to the right) and two degrees of freedom in the second direction (moving upward or downward). When the handle base 100 moves to the left, the two first spring pieces 411 of the elastic constraint part 410 on the left side are compressed and deformed by the support base 300. When the handle base 100 moves to the right, the two first spring pieces 411 of the elastic constraint part 410 on the right side are compressed and deformed by the support base 300. When the handle base 100 moves upward, the first spring pieces 411 of the two elastic constraint parts 410 on the upper side are compressed and deformed by the support base 300. When the handle base 100 moves downward, the first spring pieces 411 of the two elastic constraint parts 410 on the lower side are compressed and deformed by the support base 300. It should be noted that when the handle base 100 (support base 300) moves in other directions, its direction of motion can be decomposed into components in the first and second directions.

[0038] When the connecting bracket 400 is in the pre-installation position, the four first spring pieces 411 are rigidly connected to the bracket base 300, thereby constraining the connecting bracket 400 and the bracket base 300 together and keeping them relatively stationary.

[0039] like Figure 3-4 As shown, based on the above embodiment, the elastic constraint part 410 also has a deformable second spring piece 412. The second spring piece 412 is in contact with one end face of the support base 300. The support base 300 can overcome the constraint of the second spring piece 412 and move upward in a third direction. The third direction is perpendicular to the plane containing the first direction and the second direction.

[0040] The third direction is the Z-axis direction. The purpose of the bracket 300 moving upward in the third direction is to adjust the position of the handle base 100 in the Z-axis direction. When the connecting bracket 400 is connected to the sheet metal part 700, the second spring 412 can deform to allow the bracket 300 to move upward in the third direction.

[0041] like Figure 1-5 As shown, based on the above embodiment, the connecting bracket 400 further includes a panel portion 420, and both elastic constraint portions 410 are fixedly connected to the panel portion 420. The panel portion 420 is provided with a connecting portion for connecting to the sheet metal part 700. The connecting portion is used to connect to the mating parts on the sheet metal part 700.

[0042] Based on the above embodiments, the connecting part is configured with at least two openable latches 430, one end of which is integrally connected to the panel part 420, and each latch 430 can be stretched to form an expanded state.

[0043] In this embodiment, each locking foot 430 forms an expansion sleeve structure. When the locking foot 430 is closed, it can pass through the through hole 710 on the sheet metal part 700. After each locking foot 430 passes through the through hole 710, the panel part 420 fits against the sheet metal part 700. The screw 600 is screwed in to open each locking foot 430, thereby expanding it. After expansion, each locking foot 430 locks the through hole 710, thereby fixing the connecting bracket 400 to the sheet metal part 700.

[0044] Based on the above embodiments, an adjusting nut 500 is also included. The support base 300 has a threaded hole 310 with internal threads. The outer surface of the adjusting nut 500 is provided with external threads. The adjusting nut 500 is movably connected to the threaded hole 310 in a third direction, and the internal threads are connected to the external threads. When the adjusting nut 500 rotates, it moves in a third direction.

[0045] In this embodiment, since the adjusting nut 500 and the bracket 300 are connected by a threaded structure, the adjusting nut 500 can move upwards by rotating, thereby eliminating the gap between the bracket 300 and the panel 420. During installation, since the connecting bracket 400 is connected to the sheet metal part 700, the bracket 300 can move relative to the second spring 412 in the third direction, thereby placing the bracket 300 in a suitable position in the Z-axis direction. This results in a certain gap between the bracket 300 and the connecting bracket 400. When the adjusting nut 500 rotates, it can move towards the panel 420, causing the adjusting nut 500 to abut against the panel 420, thus eliminating the gap between the bracket 300 and the panel 420 in the Z-axis direction.

[0046] Based on the above embodiment, the adjusting nut 500 is equipped with a screw 600. The screw 600 passes through the panel portion 420 and is inserted between each locking foot 430, thereby causing each locking foot 430 to expand and open. Furthermore, each locking foot 430 is tapped by the screw 600 to create an internal thread structure to lock the screw 600.

[0047] In this embodiment, the adjusting nut 500 has a hole larger than the diameter of the screw 600 shank. The head of the screw 600 abuts against the adjusting nut 500, thereby pressing the adjusting nut 500 against the panel portion 420. The shank of the screw 600 can be radially adjusted through the hole of the adjusting nut 500, so the bracket 300 and the adjusting nut 500 are allowed to move relative to the connecting bracket 400 in the X-axis or Y-axis direction. When the connecting bracket 400 is connected to the sheet metal part 700, there is a gap between the bracket 300 and the panel portion 420 in the Z-axis direction. When the screw 600 is tightened, the adjusting nut 500 rotates and moves toward the connecting bracket 400, thereby eliminating the gap in the Z-axis direction.

[0048] like Figure 1-5 As shown, based on the above embodiments, a connection structure between a door handle and a car door sheet metal includes: a concealed car door handle, and a sheet metal part 700. The panel part 420 is in surface contact with the sheet metal part 700. The sheet metal part 700 has a through hole 710. Each locking foot 430 extends into the through hole 710, and after expanding, each locking foot 430 locks the through hole 710, thereby fixing the connecting bracket 400 to the sheet metal part 700. When each locking foot 430 is fixed to the sheet metal part 700, the handle base 100 is allowed to move slightly.

[0049] The installation process and principle of this concealed door handle are as follows: Connect the connecting brackets 400 on each alignment assembly mechanism 200 to the through holes 710 on the sheet metal part 700. Specifically, insert the clips 430 on the connecting brackets 400 into the through holes 710. After the connecting brackets 400 are fixed, if there is no deviation in the through holes 710, the handle on the handle base 100 will be perfectly aligned with the handle hole, and no adjustment of the handle base 100 is required. If there is a deviation in the through holes 710, then the position of the handle base 100 will be finely adjusted (i.e., the bracket base 300 will be moved in at least one of the first and second directions). After the above steps are completed, screws 600 are screwed into the adjusting nut 500. Screws 600 pass through the panel part 420 and into each of the retaining feet 430. After screws 600 pass into each retaining foot 430, they create a self-tapping thread structure and are fixed together with each retaining foot 430. During this process, the adjusting nut 500 moves forward in the third direction until it abuts against the panel part 420 of the connecting bracket 400, thereby eliminating the gap between the bracket base 300 and the panel part 420 in the Z-axis direction. At the same time, each retaining foot 430 is opened to lock the through hole 710, thereby fixing the handle base 100 to the sheet metal part 700 through the connecting bracket 400.

[0050] 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 positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0051] Furthermore, in this invention, descriptions involving terms such as "first," "second," and "a" are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0052] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0053] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0054] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
