Drawings
The above and other features of the present invention will become apparent with reference to the accompanying drawings, in which,
fig. 1 shows a schematic structural view of an interior and exterior body trim assembly according to the present invention.
Detailed Description
It is easily understood that, according to the technical solution of the present invention, a plurality of alternative structural modes and implementation modes can be proposed by those skilled in the art without changing the spirit of the present invention. Therefore, the following detailed description and the accompanying drawings are merely illustrative of the technical solutions of the present invention, and should not be considered as limiting or restricting the technical solutions of the present invention in their entirety or in any other way.
The directional terms upper, lower, left, right, front, rear, front, back, top, bottom and the like that are or may be mentioned in this specification are defined relative to the configurations shown in the drawings, and are relative concepts that may be changed accordingly depending on the position and the use state of the device. Therefore, these and other directional terms should not be construed as limiting terms. Furthermore, the terms "first," "second," "third," and the like are used for descriptive and descriptive purposes only and not for purposes of indication or implication as to the relative importance of the respective components.
Referring to fig. 1, there is shown a schematic structural view of an interior/exterior vehicle body assembly according to the present invention.
The interior and exterior trim assembly 1 comprises interior and exterior trim parts 11 of a vehicle body, a bolt 12 and a metal part 13 of the vehicle body, wherein the interior and exterior trim parts 11 of the vehicle body are non-metal parts of the vehicle body, and the interior and exterior trim parts 11 of the vehicle body are fixedly connected with the metal part 13 of the vehicle body through the bolt 12.
It should be understood that the vehicle interior and exterior trim 11 may be an interior trim or an exterior trim of a vehicle body, instead of a combination of interior and exterior trim. Further, the vehicle interior and exterior trim 11 or the vehicle body metal 13 does not necessarily need to refer to the entire single piece on the vehicle body, but may also cover a part of the single piece as long as it satisfies the non-metal material and the metal material, respectively, and there is no particular requirement for a specific shape, and the drawings are merely exemplary structures.
Through the technical scheme, the fastening connection between the vehicle body interior and exterior trimming parts 11 and the vehicle body metal part 13 can be realized through the bolts 12, the number of required parts is reduced, and the adaptive design of the vehicle body interior and exterior trimming parts 11 and the vehicle body metal part 13 for fastening connection is less, so that the machining time can be saved, the cost can be saved, and the machining and assembling steps can be reduced; because a riveting or welding nut can be reduced, and the process steps of rivet pulling and rivet pressing are eliminated, the weight can be reduced; repeated installation can be realized.
Specifically, the non-metal body part may include a plastic part or a composite material part of the interior and exterior trim parts of the vehicle body, and the metal body part 13 may include an aluminum alloy part or a steel plate of the vehicle body. For example, the interior and exterior body trim 11 includes a rocker panel, an a-pillar panel, a B-pillar panel, a front cabin panel, and the like, and the body metal 13 includes a rocker extrusion or a cross member, and a body steel plate. Although the vehicle body interior and exterior trim and vehicle body metal parts have been described above by way of example, this is not intended to be limiting and other suitable vehicle body parts may be included within the scope of the present disclosure.
Alternatively, the tensile strength of the body metal part 13 is below 600 Mpa, since if the tensile strength is too high, then the bolt is unnecessarily stressed and the frictional heat generation that occurs in the case of a high-speed rotation of the bolt risks fusing the threads of the bolt. In addition, under the condition that the metal piece is aluminum alloy, the thickness t of the metal piece can be selected to be more than or equal to 6 mm and more than or equal to 2 mm; under the condition that the metal piece is a steel plate, the thickness t of the metal piece can be selected to be more than or equal to 3 mm and more than or equal to 1.2 mm. Proper installation torque and connection strength are ensured through the size design, and meanwhile the size design meets the practical requirement of application, and unnecessary extra cost is avoided.
Regarding the specific connection manner between the vehicle interior and exterior trim 11 and the vehicle body metal part 13 and the bolt 12, for example, the vehicle body metal part 13 is formed with a first opening 131, the vehicle interior and exterior trim 11 is formed with a second opening 111, and the screw 121 of the bolt 12 passes through the first opening 131 and the second opening 111. These openings can be made during the execution of the connection of the present disclosure, or they can be made already in advance during the production of the corresponding parts. For example, in the case where the interior or exterior trim 11 is a plastic member, the opening of the second opening 111 is completed in an injection molding process, and the opening of the first opening 131 is completed by machining in the present connection method. It will be appreciated that the head 122 of the bolt 12 and the tip of the shank 121 are opposed to each other with respect to the vehicle interior and exterior trim 11 and the vehicle body metal 13. In addition, the bore diameter D of the first opening 131 and the thread outer diameter D of the bolt 12 may satisfy the following relation to achieve a good connection effect, for example, a proper installation torque and connection strength can be ensured by the way of thread biting depth:
d =(D-0.8 mm)±0.2 mm。
it should be understood that the thread major diameter may also be referred to as the thread major diameter, the thread major diameter (maximum diameter), etc., i.e., the diameter between the crests of the external threads, also referred to as the nominal diameter of the threads.
The bolt 12 may be configured as a self-tapping bolt capable of achieving self-tapping at the thread portion. In this case, for example, the tapping bolt may be disposed at the first opening 131, and then the tapping bolt may be driven into the first opening 131 and the second opening 111 using an electric semi-automatic torque gun, so as to form a fastening connection between the plastic member and the metal member. The use of self-tapping bolts and thus electric semi-automatic torque guns enables semi-automated mounting, thus enabling support for mounting on a final assembly line. The mounting torque ranges, for example, from 4 to 7 Nm, which is relatively small. The installation torque is a set torque after the bolt 12 is completely tightened.
Further, the interior and exterior vehicle body trim 11 may be snap-fitted to the metal body member 13. The clamping step can be performed before the bolt is connected, so that the bolt can be stably connected, and meanwhile, an auxiliary fixing effect can be provided for the connection of the metal piece and the non-metal piece.
As can also be seen from the figure, the screw 121 of the bolt 12 is embedded in the body metal 13. That is, the bolt 12 does not penetrate through the body metal 13, but ends in the body metal 13. Similarly, the head portion 122 of the bolt 12 is also disposed inside the vehicle interior and exterior trim 11. These design schemes ensure that the original appearance of the metal body 13 or the interior and exterior trim 11 is not affected by the introduction of the bolts 12, so that the original appearance design can be maintained, and the design such as the connection relationship with the peripheral parts and the layout is not affected because the external structures of the metal body and the exterior trim are not changed.
In order to allow the bolt 12 to be smoothly mounted, the end of the shank 121 of the bolt 12 is configured as a cone, such as a cone or a pyramid. Under the condition that corresponding trompil is all seted up to non-metalwork and metalwork, the cone can also play the direction and the alignment effect with corresponding trompil, is convenient for the bolt to insert wherein accurately.
Considering that the strength of the non-metal member may not be high (for example, in the case that the non-metal member is a plastic member) and the non-metal member cannot directly bear the bolt contact, so that the surface of the non-metal member is damaged during installation, the interior and exterior trim assembly 1 further includes a washer 14, and the washer 14 is sleeved on the screw rod 121 of the bolt 12 and abuts between the head portion 122 of the bolt 12 and the interior and exterior trim 11 of the vehicle body. The washer thus provides a bridging and cushioning effect for the bolt and the non-metallic member.
The washer 14 may be configured as a circular ring plate. The thickness of the washer 14 may be greater than 1 mm, and the relationship between the outer diameter D1 of the washer 14 and the outer diameter D of the thread of the bolt 12 may satisfy the following relationship:
D1 = 3D±2mm。
the gasket itself can be prevented from being deformed by the above-described dimensional design to achieve a desired pressure-distributing effect.
Specifically, the washer 14 acts to distribute the pressure as the bolt 12 is installed, which exerts pressure on the non-metallic pieces. The washer 14 does not rotate when the bolt 12 is being screwed, so the washer 14 does not spin rub against the surface of the non-metallic piece when the bolt 12 is being tightened, and thus does not damage the surface.
It should be understood that the interior and exterior body trim assembly 1 of the present invention may be installed on various vehicles, including gasoline vehicles, diesel vehicles, cars, trucks, buses, hybrid vehicles, pure electric vehicles, etc. Therefore, the subject matter of the present invention is also intended to protect various vehicles equipped with the interior and exterior body assembly 1 of the present invention.
It should be understood that all of the above preferred embodiments are exemplary and not restrictive, and that various modifications and changes in the specific embodiments described above, which may occur to those skilled in the art upon reading the teachings of the present invention, are intended to be within the scope of the appended claims.
