Description

Installation assembly, door and vehicle of outside rear-view mirror

Technical Field

The invention relates to the technical field of vehicles, in particular to a mounting assembly of an external rear-view mirror, a vehicle door and a vehicle.

Background

With the continuous improvement of living standard, the automobile has become one of the most important travel tools for people. An automobile generally refers to a non-rail-mounted vehicle driven by power (e.g., fuel, hybrid, electric, etc.) and having 4 or more wheels, and its main functions include transportation, people transportation, and so on. The automobile brings convenience, comfort and safety to people when going out, promotes the development of industry, accelerates the promotion of economy and changes the life style of people.

The rearview mirror is an important part of an automobile, can assist a driver to obtain external information such as the rear, the side and the lower part of the automobile, and plays a very important role in safe driving. The rear view mirrors can be classified into various types such as an outer rear view mirror, an inner rear view mirror, and a lower rear view mirror according to the installation position. The outer rearview mirrors are generally mounted on front doors on the left and right sides of the automobile, and a driver can conveniently observe the environment around the automobile by means of the outer rearview mirrors.

Currently, the prior art exterior rearview mirrors are usually mounted in the quarter window area of the front door (i.e., the generally triangular area of the front door near the a-pillar) or directly fixed to the door panel of the front door. Because the regional area of triangular window is less, and sheet metal construction's rigidity and intensity are relatively poor, lead to the outside rear-view mirror to produce shake and abnormal sound easily when installing on triangular window region, greatly reduced user's use experience. Although the front door panel is excellent in overall rigidity and strength, in order to enable a driver to obtain a wider field of vision, the outer mirror is generally disposed near a water line tangent to the front door (i.e., at the upper edge of the front door panel), so that when the outer mirror is fitted in a position near the water line, the door panel is highly likely to be deformed by a moment arm caused by the outer mirror extending outward, and particularly, in recent years, the weight of the mirror is getting heavier by increasing the number of internal parts thereof in order to impart more functions to the mirror. Therefore, even if the exterior mirror is fixed to the front door panel, the exterior mirror runs the risk of rattling and abnormal noise.

There is a need in the art for a new solution to the above problems.

Disclosure of Invention

In order to solve the above problems in the prior art, that is, to solve the technical problem in the prior art that the external rearview mirror is prone to generate jitter and abnormal sound, the invention provides an installation assembly of the external rearview mirror. This installation assembly includes: a door inner panel having a water cut line extending longitudinally thereof; a hinge reinforcement plate fixed to the door inner panel, the hinge reinforcement plate having a predetermined mounting area formed thereon adapted to fix the exterior mirror; the outer waist line reinforcing plate is fixed on the inner door plate and is positioned below the water tangent line; and the reinforcing piece is fixedly connected with the hinge reinforcing plate and the outer waist line reinforcing plate respectively, so that the stress generated by fixing the outer rearview mirror can be transmitted to the lower part of the water tangent line through the reinforcing piece.

The outer rearview mirror mounting assembly comprises a door inner plate, a hinge reinforcing plate, an outer waist line reinforcing plate and a reinforcing piece. The door inner panel has a water cut line extending in a longitudinal direction thereof. The hinge reinforcing plate is fixed on the inner plate of the vehicle door. A predetermined mounting area that may be adapted to fix the exterior rear view mirror is formed on the hinge reinforcement plate (i.e., the exterior rear view mirror may be fixed on the hinge reinforcement plate). The outer waist line reinforcing plate is fixed on the inner plate of the vehicle door and is positioned below the water tangent line. The reinforcement forms fixed connection with hinge reinforcing plate and outer waist line reinforcing plate respectively for the stress that fixed outside rear-view mirror produced can be conducted to the below of water tangent line through the reinforcement. By arranging the reinforcing piece and fixedly connecting the reinforcing piece with the hinge reinforcing plate and the outer waist line reinforcing plate respectively, the mounting assembly of the outer rearview mirror can transmit the stress generated when the outer rearview mirror is fixed on the hinge reinforcing plate to the reinforcing piece from the hinge reinforcing plate vertically downwards and transmit the stress to the outer waist line reinforcing plate through the reinforcing piece, so that the stress originally concentrated on the hinge reinforcing plate can be uniformly dispersed on the outer waist line reinforcing plate and other parts, and the stress on the hinge reinforcing plate is reduced. Therefore, the outer rearview mirror can be more firmly fixed on the hinge reinforcing plate, the possibility of generating jitter and abnormal sound is effectively reduced, and the use experience of a user is improved. Further, the stress generated by fixing the outer rearview mirror can be transmitted to the lower part of the water tangent line through the reinforcing piece instead of being concentrated at the position close to the water tangent line, so that the rigidity and the strength of the whole installation assembly can be enhanced, and the service life is prolonged. Accordingly, the material of the processing and mounting assembly can be properly reduced under the condition of meeting the rigidity and the strength, so that the manufacturing cost is reduced. In addition, since the mounting assembly of the exterior rear view mirror of the present invention improves the rigidity and strength of a predetermined mounting region by adding a separate reinforcement member without changing the structures of the door inner panel, the hinge reinforcement plate, the outer belt line reinforcement plate, and the like, the fitting property of the mounting assembly of the exterior rear view mirror of the present invention is also significantly improved.

With continued reference to fig. 2-4b, in one or more embodiments, the door inner panel 31 is formed from galvanized steel or other suitable metal material by a roll forming process. The door inner panel 31 has a water cut line 311 extending substantially in the longitudinal direction thereof. An inner water cutting structure (not shown) is arranged at the position of the water cutting line 311, so that the window glass 1013 can cut off impurities such as water drops, water mist and dust on the inner surface of the glass in the lifting process, and meanwhile, the window glass can play a role in beauty. The door inner panel 31 is formed on the inner side of the door panel 1012. In the case where the front door 101 is a framed door (i.e., a framed door), the door inner panel 31 may be integrally press-molded with a sash of the front door 101. Alternatively, the sash of the front door 101 may be manufactured separately from the door inner panel 31 and then fixedly attached by welding, screws, or the like.

With continued reference to fig. 2-4b, in one or more embodiments, the hinge reinforcement plate 32 is formed from a galvanized steel sheet or other suitable metallic material by a stamping process. The hinge reinforcement plate 32 is fixed to an upper portion of the door inner panel 31. Preferably, the hinge reinforcement plate 32 is fixedly coupled to the door inner panel 31 by a Resistance Spot Welding (i.e., Resistance Spot Welding) process, so that a firm and stable fixed coupling is formed between the hinge reinforcement plate 32 and the door inner panel 31. Alternatively, the hinge reinforcement plate 32 may be fixed to the door inner panel 31 by other suitable means, such as screw fixing. A predetermined mounting area 321 for fixing the exterior mirror 20 is provided on the hinge reinforcing plate 32, and the predetermined mounting area 321 is close to the water cutting line 311. In one or more embodiments, the predetermined mounting area 321 is located at a position of the hinge reinforcement panel 32 near a quarter window area 1011 of the front door 101.

In one or more embodiments, there are 3 rearview mirror mounting holes spaced apart from each other within the predetermined mounting area 321. The 3 rearview mirror mounting holes are a first rearview mirror mounting hole 3211, a second rearview mirror mounting hole 3212, and a third rearview mirror mounting hole 3213, respectively.

The first rearview mirror mounting hole 3211, the third rearview mirror mounting hole 3213, and the fourth rearview mirror mounting hole 3214 are all disposed above the outer beltline reinforcing plate 34, so that the outer rearview mirror 20 can be conveniently assembled to the corresponding rearview mirror mounting hole without being blocked by the outer beltline reinforcing plate 34, the door outer panel, and the like, thereby improving the assembly efficiency (it should be noted that the heights of the door outer panel and the outer beltline reinforcing plate 34 in the vertical direction are substantially the same). In addition, the first rearview mirror mounting holes 3211, the third rearview mirror mounting holes 3213, and the fourth rearview mirror mounting holes 3214 are also arranged in a substantially triangular shape so as to firmly fix the exterior rearview mirror 20. In another alternative embodiment, the number of the mirror mounting holes is set to 4, i.e., including the first mirror mounting hole 3211, the second mirror mounting hole 3212, the third mirror mounting hole 3213, and the fourth mirror mounting hole 3214, so that the stress generated by fixing the outer mirror 20 can be dispersed more uniformly to ensure the degree of fastening of the outer mirror 20.

It is noted that mounting holes are provided in the door inner panel 31 so as to be opposed to each of the mirror mounting holes and aligned with each other, so that the outer mirror 20 can be fixed to the sheet metal structure formed by connecting the door inner panel 31 and the hinge reinforcement panel 32 by a mounting member (not shown) to obtain a more firm and stable fixed connection.

With continued reference to fig. 2-4b, in one or more embodiments, the window guide 33 is configured to be formed from a galvanized steel sheet or other suitable metallic material by a stamping process. A lifting groove 331 allowing the window glass 1013 to be lifted and lowered in the vertical direction is formed on the window rail 33 so that the user can conveniently adjust the lifting and lowering of the window glass 1013 according to actual needs. The window rail 33 extends substantially vertically below the water cut line 311 and forms a fixed connection with the hinge reinforcement plate 32. Preferably, the window guide 33 is configured to form a fixed connection with the hinge reinforcement 32 and the door inner panel 31 by means of three-layer spot welding to obtain a firm and stable connection.

FIG. 5 is a cross-sectional view of an embodiment of the exterior rear view mirror mounting assembly of the present invention taken along section line A-A of FIG. 4 a; fig. 7 is a schematic structural view of an embodiment of a reinforcing member in the mounting assembly of the exterior rear view mirror of the present invention. In one or more embodiments, as shown in fig. 5 and 7, the reinforcement 35 is machined from galvanized steel or other suitable metallic material. The reinforcement 35 is configured as a curved plate-like structure. Specifically, the curved plate-like structure has a first fixed segment 351 abutting against the hinge reinforcement plate 32, a second fixed segment 352 abutting against the window rail 33, and a third fixed segment 353 abutting against the outer beltline reinforcement plate 34. The first fixing section 351 and the second fixing section 352 are connected by an arc-shaped connecting section 354. The curved plate-like structure not only enables the reinforcement 35 to have a relatively simple structure to simplify the manufacturing process and reduce the manufacturing cost, but also enables easier feature avoidance in the structural design, and simultaneously can increase the rigidity and strength of the reinforcement 35 itself.

As shown in fig. 5, in one or more embodiments, the first fixing section 351 is fixedly connected to the hinge reinforcement plate 32 and the door inner panel 31 by three-layer spot welding, the second fixing section 352 is fixedly connected to the window rail 33 by two-layer spot welding, and the third fixing section 353 is fixedly connected to the outer beltline reinforcement plate 34 by two-layer spot welding. With the above arrangement, the reinforcement 35 can be firmly and fixedly connected to the hinge reinforcement 32, the door inner panel 31, the window guide 33, and the outer belt line reinforcement 34, so that the mounting assembly 30 has a stable structure.

With continued reference to FIG. 5, in one or more embodiments, the hinge reinforcement panel 32, the window guide 33, and the outer beltline reinforcement panel 34 are sequentially spaced apart in a thickness direction of the door inner panel 31 (i.e., transverse to the door inner panel 31). By configuring the hinge reinforcement plate 32, the window guide rail 33, and the outer beltline reinforcement plate 34 to be spaced apart in sequence in the transverse direction, it is possible to make the stress generated by fixing the outer mirror 20 not only be conducted vertically to the lower side of the water tangent line 311 but also be conducted in the transverse direction, so that the stress can be dispersed more uniformly, thereby improving the rigidity and strength of the mounting assembly 30.

FIG. 6 is a cross-sectional view of an embodiment of the exterior rear view mirror mounting assembly of the present invention taken along section line B-B of FIG. 4 a. As shown in fig. 6, in one or more embodiments, at least one first reinforcing protrusion 312 protruding toward a direction away from the hinge reinforcement plate 32 and spaced apart from each other is formed on the door inner panel 31 to enhance the rigidity and strength of the door inner panel 31. The number of the first reinforcing protrusions 312 may be 2, or other suitable number more or less than 2, such as 1, 3, etc. In one or more embodiments, at least one second reinforcing protrusion 322 protruding opposite and opposite to each first reinforcing protrusion 312 is formed on the hinge reinforcement plate 32 such that each first reinforcing protrusion 312 and the corresponding second reinforcing protrusion 322 enclose a reinforcing cavity. In one or more embodiments, the reinforcement cavities include a first reinforcement cavity 323a and a second reinforcement cavity 323b that are spaced apart from each other. In one or more embodiments, the first reinforcing cavity 323a and the second reinforcing cavity 323b are configured to extend substantially in the vertical direction and pass through the extension line of the water tangent line 311, i.e., the first reinforcing cavity 323a and the second reinforcing cavity 323b vertically intersect with the extension line of the water tangent line 311, so as to further improve the rigidity and strength of the door inner panel 31 and the hinge reinforcing panel 32 and prolong the service life thereof. In one or more embodiments, the angle formed by the central extension direction of the first reinforcement cavity 323a and the second reinforcement cavity 323b in the vertical direction and the clamping of the water tangent line 311 is 10 ° or more. Further, the angle range formed by the central extending direction of the first reinforcing cavity 323a and the second reinforcing cavity 323b in the vertical direction being sandwiched with the water tangent line 311 is 15 ° or more. Further, the central extension direction of the first and

second reinforcement cavities

323a and 323b in the vertical direction is sandwiched with the water tangent line 311 to form an angle ranging from 30 ° to 120 °. In one or more embodiments, the first reinforcement cavity 323a has a first length L1 and a first width W1; the second reinforcement cavity 323b has a second length L2 and a second width W2. The first length L1 and the first width W1, and the second length L2 and the second width W2 are as large as possible within the allowable range of the size, and a rounded transition is formed between the respective portions of each reinforcing cavity to prevent stress concentration.

In one or more embodiments, the inventive mounting assembly 30 includes only the inner door panel 31, the hinge reinforcement panel 32, the outer beltline reinforcement panel 34, and the reinforcement 35, i.e., does not include the window guide 33. The door inner panel 31 has a water cut line 311 extending in the longitudinal direction. The hinge reinforcement plate 32 is fixed to the door inner panel 31. A predetermined mounting area 321 to which the exterior mirror 20 can be fixed is formed on the hinge reinforcement plate 32. The outer belt line reinforcement plate 34 is fixed to the door inner panel 31 and is located below the water cut line 311. The reinforcement 35 is fixedly connected to the hinge reinforcement plate 32 and the outer waist line reinforcement plate 34, respectively, so that stress generated by fixing the outer rear view mirror 20 can be transmitted to below the water cut line 311 through the reinforcement 35. It should be noted that the undescribed parts in this embodiment may be configured the same as any of the above-described embodiments, and are not described herein again.

In order to verify the influence of the mounting assembly 30 of the external rear view mirror 20 of the invention on the overall vehicle mode and the static rigidity of the mounting hole of the rear view mirror, one embodiment of the invention is selected to carry out a comparison experiment with the mounting assembly in the prior art. The inventive mounting assembly 30 includes a door inner panel 31, a hinge reinforcement panel 32, a window rail 33, an outer beltline reinforcement panel 34, a reinforcement 35, and the like, and a first reinforcement cavity 323a and a second reinforcement cavity 323b are formed in the door inner panel 31 and the hinge reinforcement panel 32. The reinforcement member 35 is not included in the comparative mounting assembly, and the first reinforcement cavity 323a and the second reinforcement cavity 323b are not included in the comparative mounting assembly (i.e., the door inner panel 31 does not include the first reinforcement protrusion 312, and the hinge reinforcement panel 32 does not include the second reinforcement protrusion 322). In addition, in order to verify the influence of the arrangement position on the static rigidity of the rearview mirror mounting holes, the mounting assembly 30 of the present invention is provided with 4 rearview mirror mounting holes, namely a first rearview mirror mounting hole 3211, a second rearview mirror mounting hole 3212, a third rearview mirror mounting hole 3213 and a fourth rearview mirror mounting hole 3214, while the comparative mounting assembly only comprises 3 rearview mirror mounting holes which are respectively identical to the arrangement positions of the first rearview mirror mounting hole 3211, the second rearview mirror mounting hole 3212 and the third rearview mirror mounting hole 3213. In addition to the differences described above, the other component configurations of the inventive mounting assembly 30 and the comparative mounting assembly are identical, and the test conditions are also identical.

It should be noted that the "mode" is a natural vibration characteristic of the structural system, and each mode has specific modal parameters such as a natural frequency, a damping ratio, a mode shape, and the like, and these modal parameters can be obtained by calculation or experimental analysis. "static stiffness" is the ability of a structure to resist deformation under a particular static disturbance, and is generally measured by the degree of deformation of the structure under a static load, a value which can be obtained experimentally.

TABLE 1 comparative experiment results of mechanical properties of installation assembly of exterior rear view mirror

As can be seen from table 1, by using the mounting assembly 30 of the external rear view mirror 20 of the present invention, the overall mode of the vehicle 1 of the present invention is improved by 9.25%, so that the overall structure of the vehicle is more stable. In addition, the static rigidity of the first rearview mirror mounting hole, the second rearview mirror mounting hole and the third rearview mirror mounting hole are improved to different degrees, and the amplification is large (the minimum amplification is 37.26%, and the maximum amplification is 85.23%).

With continued reference to Table 1, the fourth mirror mounting hole 3214 has a static stiffness of 249N/mm which is greater than the static stiffness of each mirror mounting hole in the comparative mounting assembly. Therefore, in one or more embodiments, when the inventive mounting assembly 30 includes the first, third, and fourth mirror mounting holes, not only can the rigidity and strength requirements be satisfied to securely fix the exterior mirror 20 to the mirror mounting holes, but also each mirror mounting hole can be disposed above the outer fascia stiffener 34 to avoid the outer fascia stiffener 34 and the like, thereby improving assembly efficiency.

So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
