Description

Technical Field

[0001] The present application relates to the technical field of vehicles, and particularly relates to a semi-hidden door handle positioning and installation structure and a vehicle. Background Art

[0002] At present, vehicles tend to adopt a new device of a hidden door handle to enhance the sense of technology. Common hidden door handles include two major categories. One is a completely hidden type where, in the locked state, it is coplanar with the door sheet metal but there is no operating space for the hand. The appearance of the outer handle of this form is integrated with the door, but the disadvantages are also obvious. It is easy to freeze in winter, resulting in the handle being unable to pop out and open the door smoothly. As this problem is exposed more and more, the application of another semi-hidden door handle has begun to be favored by vehicle manufacturers and consumers. The semi-hidden door handle has an operating space for the hand, and its outer surface can still be hidden between the door sheet metals.

[0003] In the related art, the completely hidden door handle system mainly relies on a gasket to position with the flange of the outer door panel. This positioning usually requires the assistance of a tooling, and it is impossible to perform the Y-direction limit towards the vehicle interior. It is necessary to hold the handle and push it outwards in the Y-direction and then perform the next assembly, which is extremely inconvenient to operate. Further, the handle is fixed by bolting three adjustable nuts of the door handle system to the reinforcement plate of the outer door panel, that is, the handle is fixed. This solution has a complex structure, a large assembly difficulty, a long dimension chain, general precision control, and a high cost.

[0004] For the positioning scheme of a common semi-hidden handle, in addition to the above scheme, in another scheme two, it is necessary to rely on 2 to 3 bolt installation "ear holes" extended from the flange of the outer door panel to match and fix with the door handle. On the one hand, it poses a great challenge to the sheet metal stamping forming, and on the other hand, it has a very high requirement for the system precision matching. It is easy to have problems such as misaligned holes during installation and uneven clearance and surface difference caused by large fluctuations in part dimensions, resulting in abnormal assembly. In addition, the sheet metal fixing points of this scheme have poor rigidity, and the probability of appearance deformation and other problems is relatively high after 3 to 5 years of use.

[0005] Therefore, it is necessary to study and improve the above structure, and provide a semi-hidden door handle positioning and installation structure and a vehicle, in order to achieve a more practical value purpose. Summary of the Invention

[0044] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts fall within the scope of protection of this application.

[0045] In view of the deficiencies or one of the deficiencies proposed in the above background art, the embodiments of this application provide a semi-hidden door handle positioning and installation structure and a vehicle, which have the advantages of simple structure, reliable performance, low difficulty in matching with the door sheet metal, simple process operation, and low weight and cost.

[0046] See Figures 1 to 5 As shown, in the first aspect of the embodiments of this application, a semi-hidden door handle positioning and installation structure is provided, including:

[0047] A handle assembly 1, which includes a handle bottom shell 11 and a handle 12 installed in the handle bottom shell 11. A circumferential flange 111 is provided on the outer circle of the handle bottom shell 11;

[0048] An outer door panel 2, on which a handle installation hole 21 for accommodating the handle bottom shell 11 is provided. A first flanging 211 for circumferentially limiting the circumferential flange 111 is provided on the edge of the handle installation hole 21, and a second flanging 212 for axially limiting the circumferential flange 111 along the installation direction is provided on the first flanging 211;

[0049] A fixing seat 3, which abuts against the inner wall of the outer door panel 2. The fixing seat 3 is connected to the handle bottom shell 11 through fasteners to fasten the circumferential flange 111 on the second flanging 212.

[0050] The semi-hidden door handle positioning and installation structure of the embodiments of this application includes a handle assembly 1 and a fixing seat 3. Through the form of assembling two components, the outer door panel 2 is "clamped" to form a positioning assembly. No additional assembly carrier is required, nor is an auxiliary positioning device required. Only by forming a pre-hanging between the handle assembly 1 and the outer door panel 2, and then after completing the assembly with the fixing seat 3, the bolt fasteners are tightened from the inside of the vehicle towards the outside in the vehicle body width direction, and the positioning assembly of the handle system can be completed.

[0051] While ensuring the performance strength of the handle, the process operation is convenient. At the same time, the counter part of the door handle is only the outer door panel 2, the system matching dimension chain is small, and the appearance gap and surface difference are easier to ensure. In addition, since no additional device is required for the matching system between the handle and the door sheet metal, there are also great advantages in cost and weight. That is, the handle positioning and installation solution of this application has the advantages of simple structure, reliable performance, low difficulty in matching with the door sheet metal, simple process operation, and low weight and cost.

[0052] Specifically, the door handle system in this embodiment consists of two main parts: the handle assembly 1 and the fixed seat 3, and also includes a car door sheet metal that matches the handle system: the outer car door panel 2. A handle mounting hole 21 is provided on the outer car door panel 2, and a first flanging 211 is formed by stamping around the circumference of the handle mounting hole 21. A second flanging 212 is formed by stamping on the first flanging 211, forming a stamping flanging with a cross-section similar to an "S" shape as the matching boundary of the handle system.

[0053] The handle assembly 1 includes a handle bottom shell 11 and a handle 12 installed inside the handle bottom shell 11. Among them, the handle bottom shell 11 serves as the main limiting component to complete the pre-hanging of the car door handle assembly 1 on the outer car door panel 2. In this embodiment, a circular flange 111 is integrally formed on the outer circle of the handle bottom shell 11. After the handle bottom shell 11 is installed into the handle mounting hole 21, the first flanging 211 can form a preliminary circumferential positioning for the circular flange 111, and cooperate with the second flanging 212 to stop the circular flange 111 in the installation direction of the handle bottom shell 11, thereby completing the pre-hanging of the car door handle assembly 1 on the outer car door panel 2.

[0054] The fixed seat 3 is assembled from the inside to the outside of the outer car door panel 2. The fixed seat 3 abuts against the inner wall of the outer car door panel 2. By tightening two bolts to connect the fixed seat 3 and the handle bottom shell 11, the fixed seat 3 can tighten the circular flange 111 of the handle bottom shell 11 on the second flanging 212 through the bolts, realizing the form of positioning and assembling by combining two components to "clamp" the outer car door panel 2. This ensures reliable matching between the handle and the sheet metal system, and on the one hand, also meets the simplicity and convenience of the process operation. At the same time, the system has a small matching dimension chain, and it is easier to ensure the appearance gap and surface difference.

[0055] First, in some alternative embodiments: Refer to Figures 1 to 8 As shown, the embodiment of the present application provides a semi-hidden door handle positioning and installation structure. A claw 112 is provided on the handle bottom shell 11 of the semi-hidden door handle positioning and installation structure, and the gap formed between the claw 112 and the circular flange 111 is used to clamp the second flanging 212.

[0056] A claw 112 is provided on the handle bottom shell 11 of the embodiment of the present application. By using the gap formed between the claw 112 and the circular flange 111, the second flanging 212 can be clamped, and after the pre-hanging of the car door handle assembly 1 on the outer car door panel 2, when installing the fixed seat 3 and the fasteners, there is no need to hold the handle assembly 1 by hand, which can improve the convenience of installation.

[0057] Exemplarily, in this embodiment, three claws 112 are integrally connected to the bottom handle shell 11. Two claws 112 are located at both ends of the lower part of the bottom handle shell 11 and are non-deformable; the remaining one claw 112 is located at the upper part of the bottom handle shell 11 and is elastic, and can be bent and deformed like an elastic reed; the three claws 112 are located on the back of the annular flange 111 and are used to match the back of the second flanging 212, and cooperate with the annular flange 111 to limit the annular flange 111 in the vehicle body width direction.

[0058] Specifically, the method of installing the handle assembly 1 of the vehicle door on the vehicle door sheet metal is as follows: Assemble from the outside to the inside of the vehicle door sheet metal. When approaching the outer door panel 2, first insert the two non-deformable claws 112 at the lower end of the handle assembly 1 to the back of the lower second flanging 212, and use the lower claws 112 as a fulcrum to screw the handle assembly 1 upward into the handle mounting hole 21. The upper elastic claw 112 is bent and deformed after being squeezed by the upper second flanging 212 and reset on the back of the second flanging 212, thereby completing the matching installation of the handle assembly 1 and the handle mounting hole 21.

[0059] During this process, it is only necessary to control the gap between the engineering reserved claw 112 and the back of the second flanging 212 on the outer door panel 2 to be between 0.5 and 1 mm, and the conventional tolerance of the flanging stamping on the outer door panel 2 to be controlled within ±0.3 to 0.5 mm, then the pre-hanging of the handle assembly 1 on the outer door panel 2 can be successfully completed.

[0060] First aspect, in some alternative embodiments: Refer to Figure 6 As shown, the embodiment of the present application provides a semi-hidden vehicle door handle positioning and installation structure. A plurality of limiting ribs 113 connected to the back of the annular flange 111 are circumferentially spaced on the bottom handle shell 11 of the semi-hidden vehicle door handle positioning and installation structure. The limiting ribs 113 are used to block and position the stop of the second flanging 212.

[0061] A plurality of limiting ribs 113 are integrally connected to the outer surface of the bottom handle shell 11 of the embodiment of the present application. After the bottom handle shell 11 is installed into the handle mounting hole 21, the limiting ribs 113 can abut against the stop of the second flanging 212. The stop of the second flanging 212 is the end face of the second flanging 212 away from the first flanging 211. Since the plurality of limiting ribs 113 are circumferentially distributed, the plurality of limiting ribs 113 all abut against the stop of the second flanging 212, so that the circumferential limit of the bottom handle shell 11 can be accurately completed, and the bottom handle shell 11 can be prevented from shaking relative to the outer door panel 2 in the vehicle length and height directions.

[0062] Exemplarily, in this embodiment, the bottom handle shell 11 is a plastic part formed by integral injection molding. Four groups of limiting ribs 113 are distributed on the upper and lower parts of the outer surface of the bottom handle shell 11, and one group of limiting ribs 113 is distributed on each of the left and right parts. Each group of limiting ribs 113 is integrally connected to the annular flange 111. After the bottom handle shell 11 is installed into the handle mounting hole 21, the annular flange 111 abuts against the front surface of the second flanging 212, and multiple limiting ribs 113 abut against the end surface of the second flanging 212 away from the first flanging 211, thereby completing the circumferential limitation of the bottom handle shell 11. In addition, the injection-molded limiting ribs 113 are convenient for grinding and fine-tuning of dimensions.

[0063] In a first aspect, in some alternative embodiments: Refer to Figure 7 As shown, the embodiment of the present application provides a semi-hidden door handle positioning and mounting structure. An anti-misalignment notch 213 is provided on the second flanging 212 of the semi-hidden door handle positioning and mounting structure, and an anti-misalignment convex block 114 is provided at a position on the bottom handle shell 11 corresponding to the anti-misalignment notch 213.

[0064] An anti-misalignment notch 213 is formed on the second flanging 212 of the embodiment of the present application. The anti-misalignment notch 213 is trapezoidal and is located above the handle mounting hole 21. An anti-misalignment convex block 114 is integrally connected to the bottom handle shell 11. The anti-misalignment convex block 114 is rectangular. During the process of installing the bottom handle shell 11 into the handle mounting hole 21, the anti-misalignment convex block 114 can enter the anti-misalignment notch 213, and then the bottom handle shell 11 can be successfully installed. The anti-misalignment convex block 114 provided on the bottom handle shell 11 matching the anti-misalignment notch 213 can simply and effectively prevent the handle from being misinstalled.

[0065] In a first aspect, in some alternative embodiments: Refer to Figure 9 and Figure 10 As shown, the embodiment of the present application provides a semi-hidden door handle positioning and mounting structure. The fixed seat 3 of the semi-hidden door handle positioning and mounting structure is a shell structure with one end open. The bottom handle shell 11 is located inside the fixed seat 3. A support point for abutting against the inner wall of the vehicle door outer panel 2 is provided at the open end of the fixed seat 3, and an assembly hole 31 for installing fasteners is provided on the back of the fixed seat 3 far away from the open end.

[0066] The fixed seat 3 of the embodiment of the present application is a shell structure with one end open, which can accommodate the bottom handle shell 11. A support point for abutting against the inner wall of the vehicle door outer panel 2 is provided at the open end of the fixed seat 3. The support point can reduce the size of the abutting surface with the inner wall of the vehicle door outer panel 2 and lower the installation accuracy requirements. In addition, an assembly hole 31 is provided on the back of the fixed seat 3 far away from the open end. After the fixed seat 3 abuts against the wall of the vehicle door outer panel 2, it is convenient to directly tighten the bottom handle shell 11 on the vehicle door outer panel 2 by using the assembly hole 31 to install bolt fasteners.

[0067] Exemplarily, the fixed seat 3 in this embodiment is a plastic part formed by integral injection molding. As an assembly part of the handle bottom shell 11, the fixed seat 3 adopts a shell structure with an open end at one side. The part of the handle bottom shell 11 passing through the handle mounting hole 21 can be covered by the fixed seat 3. The support points on the fixed seat 3 are arranged at the upper and lower parts of the fixed seat 3. After the handle bottom shell 11 and the vehicle outer door panel 2 are pre-hung, the fixed seat 3 covers the handle bottom shell 11 from the inside to the outside of the vehicle outer door panel 2. The supports at the upper and lower parts of the fixed seat 3 are on the inner wall of the vehicle outer door panel 2. Finally, the handle bottom shell 11 is directly tightened on the vehicle outer door panel 2 by installing bolt fasteners through the assembly holes 31.

[0068] In a first aspect, in some alternative embodiments: Refer to Figure 3 , Figure 9 and Figure 10 As shown in, the embodiment of the present application provides a semi-hidden door handle positioning and mounting structure. A positioning pin 115 is arranged on the back surface of the handle bottom shell 11 of the semi-hidden door handle positioning and mounting structure, and a positioning hole 32 for inserting the positioning pin 115 is arranged on the back surface of the fixed seat 3 far from the open end.

[0069] The positioning pin 115 is integrally connected to the back surface of the handle bottom shell 11 in the embodiment of the present application, and a positioning hole 32 for inserting the positioning pin 115 is arranged on the back surface of the fixed seat 3 far from the open end. Through the mutual cooperation of the positioning pin 115 and the positioning hole 32, after the handle assembly 1 and the vehicle outer door panel 2 are pre-hung, the fixed seat 3 can be quickly installed, so that the positioning pin 115 on the handle bottom shell 11 passes through the positioning hole 32 on the fixed seat 3, forming a preliminary assembly of the handle assembly 1 and the fixed seat 3, and the vehicle outer door panel 2 is clamped between these two components.

[0070] Exemplarily, the handle bottom shell 11 and the positioning pin 115 in this embodiment are formed by integral injection molding. The positioning pin 115 includes a cross pin located on the left side of the back surface of the fixed seat 3 with a cross-shaped cross section, and a rectangular pin located on the right side of the back surface of the fixed seat 3 and inclined. The positioning hole 32 on the fixed seat 3 includes a square hole for cooperating with the cross pin and a rectangular hole for cooperating with the rectangular pin.

[0071] The upper handle bottom shell 11 of the handle assembly 1 serves as an assembly carrier for the fixed seat 3. After the handle assembly 1 and the vehicle outer door panel 2 are pre-hung, the fixed seat 3 passes through the inner door panel hole from the inner direction of the door sheet metal and is pre-hung with the handle assembly 1 through the cross pin and the rectangular pin. At this time, a preliminary assembly of the handle assembly 1 and the fixed seat 3 is formed, and the vehicle outer door panel 2 is clamped between these two components. Finally, the handle bottom shell 11 is directly tightened on the vehicle outer door panel 2 by installing bolt fasteners.

[0072] In a first aspect, in some alternative embodiments: Refer to Figure 11As shown, an embodiment of the present application provides a semi-hidden door handle positioning and mounting structure. A circumferential assembly gap 4 is formed between the side wall of the handle bottom shell 11 and the side wall of the fixed seat 3 of the semi-hidden door handle positioning and mounting structure.

[0073] The inner diameter of the fixed seat 3 in the embodiment of the present application is larger than the outer diameter of the handle bottom shell 11. The fixed seat 3 can cover the handle bottom shell 11. A circumferential assembly gap 4 is formed between the side wall of the handle bottom shell 11 and the side wall of the fixed seat 3, which can avoid assembly interference and reduce the assembly difficulty. When the fastening points and pin positioning errors between the fixed seat 3 and the handle bottom shell 11 are large, it is convenient to adjust the relative positions of the fixed seat 3 and the handle bottom shell 11 to compensate for the alignment error and ensure smooth assembly.

[0074] In a first aspect, in some alternative embodiments: Refer to Figures 9 to 14 As shown, an embodiment of the present application provides a semi-hidden door handle positioning and mounting structure. The support points of the semi-hidden door handle positioning and mounting structure include an upper boss 33 and a lower boss 34 located at the open end of the fixed seat 3. Both the upper boss 33 and the lower boss 34 are in contact with the inner wall of the outer door panel 2 through an elastic gasket 5.

[0075] The support points of the embodiment of the present application include an upper boss 33 and a lower boss 34 located at the open end of the fixed seat 3. Both the upper boss 33 and the lower boss 34 are in contact with the inner wall of the outer door panel 2 through an elastic gasket 5. The elastic gasket 5 can absorb assembly tolerances and disperse the supporting force to ensure the supporting strength of the door sheet metal and improve the system reliability.

[0076] Exemplarily, a gap of 0.5 to 1 mm is reserved between the upper boss 33 and the lower boss 34 and the inner wall of the outer door panel 2, and an elastic gasket 5 with an assembly material thickness of 1 to 2 mm is used to absorb assembly tolerances. The elastic gasket 5 is made of felt, which is wear-resistant and elastic, can play an anti-vibration effect, can evenly disperse the extrusion force, and ensure the supporting stability. In addition, the felt can be fixed on the upper boss 33 and the lower boss 34 by bonding to facilitate installation.

[0077] In a first aspect, in some alternative embodiments: Refer to Figures 9 to 14 As shown, an embodiment of the present application provides a semi-hidden door handle positioning and mounting structure. The lower end of the upper boss 33 of the semi-hidden door handle positioning and mounting structure extends to the back of the second flanging 212, and the upper boss 33 is in contact with the back of the second flanging 212 through an elastic gasket 5.

[0078] The lower end of the upper boss 33 of the embodiment of the present application extends to the back surface of the second flanging 212. The upper boss 33 is in contact with the back surface of the second flanging 212 through the elastic gasket 5. By adjusting the shape of the upper boss 33, the upper boss 33 is made to contact the back surface of the second flanging 212. Compared with the upper boss 33 directly contacting the upper position of the second flanging 212, the outer door panel 2 will not be squeezed and deformed, and the appearance beauty of the outer door panel 2 can be ensured.

[0079] See Figures 1 to 14 As shown, the second aspect of the embodiment of the present application provides a vehicle, including:

[0080] The semi-hidden door handle positioning and installation structure of any one of the above embodiments.

[0081] The vehicle of the embodiment of the present application adopts the semi-hidden door handle positioning and installation structure of any one of the above embodiments. When installing the door handle, no additional sheet metal assembly carrier is required, nor is an auxiliary positioning device required. Only by forming a pre-hanging between the door handle assembly 1 and the outer door panel 2, and then completing the assembly with the door handle fixing seat 3, and then driving bolt fasteners from the inside of the vehicle towards the outside of the vehicle, the positioning and assembly of the handle system can be completed.

[0082] In summary, on the one hand, the solution of the present application ensures reliable matching between the handle and the sheet metal system, and on the other hand, it also meets the simplicity and convenience of the process operation. At the same time, the counter part of the door handle is only the outer door panel 2, the system matching dimension chain is small, and the appearance gap and surface difference are easier to ensure. In addition, since the matching system between the handle and the sheet metal does not require an additional device, the positioning can be completed only between the plastic parts of the handle system, and there are also great advantages in terms of cost and weight.
