Technical Field

Exemplary embodiments relate to a parts mounting structure for a vehicle.

Background

Generally, a fastening member including a bolt and a nut is a typical mechanical element for joining two or more parts. These fastening members are used in various mechanical industry fields including a vehicle manufacturing field.

In a process of assembling the assembled parts to the vehicle body during the production of the vehicle, the assembled parts are assembled to the vehicle body by using bolts and nuts.

On the other hand, electric buses and hydrogen-powered buses have been developed gradually in recent years according to government policies promoting environmentally friendly vehicles. Various electric components are installed on an electric bus or a hydrogen powered bus to control and manage driving of the driving motor and charging of the battery module. These electrical components are mounted in a modular (integrated) form for ease of assembly and safety.

As a module frame for mounting electric parts on a vehicle body in a modular form, a frame structure made of square pipes is generally used in order to secure assemblability of the electric parts and protect the electric parts from impact.

For example, in the past, a hole was machined on one side of a square pipe of a module frame, a nut was fixed to the inside of the hole, and a bolt was engaged in the nut to mount a target member to the module frame.

However, this type of mounting can result in the mounted components falling under high torque conditions due to insufficient strength.

In another example, holes are drilled in the up-down direction on square tubes of the module frame, collars are attached to the holes, bolts are attached to the collars, and the bolts are engaged to mounting brackets of target components to be assembled.

However, since this mounting manner is to engage the nut to the bolt, it is difficult for a worker to engage the nut when the target member is oversized.

The above information disclosed in the background is only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not constitute prior art known to those skilled in the art.

Referring to fig. 1 to 3, a vehicle component mounting unit 100 according to an exemplary embodiment may be applied to a process of mounting various component assemblies 1 on a vehicle body in a vehicle manufacturing plant.

Further, the vehicle component mounting unit 100 according to the exemplary embodiment may be applied to the following process: the component assembly 1 applied to various electric parts of an electric bus or a hydrogen powered bus is mounted on a vehicle body in the form of a module.

Herein, the component assembly 1 may be mounted on a module frame 3 (hereinafter, referred to as a "frame" for convenience) configured on a vehicle body by fastening members such as bolts passing through a mounting bracket 5.

For example, the frame 3 partitions the electrical components of the component assembly 1, and the frame may include a square tube 3a having upper and lower surfaces and a closed cross-section as a frame assembly supporting the component assembly 1.

In the above, as an example of the target component, the electric components of the component assembly 1 are described as being mounted on the frame 3, but the present disclosure is not necessarily limited thereto. Various vehicle assembly components such as engines, transmissions, and suspensions may also employ the spirit of the present disclosure when mounted to a vehicle body.

Hereinafter, the mounting structure of the component assembly 1 will be described based on an example of mounting the component assembly 1 on the upper surface of the frame 3, as shown in the drawings. For ease of understanding, the portions facing upward in the drawings are referred to as upper end portions, upper ends, upper surfaces, etc., and the portions facing downward are referred to as lower end portions, lower ends, lower surfaces, etc.

However, the above definition of the direction has a relative meaning, and the above reference direction does not necessarily limit the reference direction of the present disclosure since the direction may be changed with respect to the frame 3 according to the mounting direction of the component assembly 1 or the like.

Further, hereinafter, "end (one end, the other end, etc.)" may be defined as either end or may be defined as a portion (one end, the other end, etc.) including the end.

The vehicle component mounting unit 100 according to the exemplary embodiment is made of a structure that can secure mounting strength and torque of the component assembly 1 for the frame 3 and secure reliability of the bolting work.

For this purpose, the vehicle component mounting unit 100 according to the exemplary embodiment includes a mounting plate 10, a weld nut 30, and a joint bolt 50.

In an exemplary embodiment, the mounting plate 10 is a plate on which the mounting bracket 5 of the component assembly 1 is mounted, and may be a rectangular plate having an upper surface and a lower surface.

At least one bolt coupling hole 11 is formed in the mounting plate 10, and the lower surface may be coupled with the upper surface of the frame 3. Mounting plate 10 may be welded (e.g., CO)₂Gas shielded welding) is attached to the upper surface of the frame 3.

Here, the mounting plate 10 includes a first reinforcing surface 13 supporting the mounting bracket 5 of the component assembly 1 and a second reinforcing surface 15 supporting the upper surface of the frame 3.

In the mounting plate 10, a slot hole 17 having a slit shape is formed separately from the bolt coupling hole 11. The slot hole 17 is configured to ensure welding performance of the mounting plate 10 to the frame 3.

Thus, as shown in fig. 4, the mounting plate 10 may include a first welding portion 21 welded to the frame 3 at the edge end of the slot hole 17 and a second welding portion 22 welded to the frame 3 at both ends.

In the exemplary embodiment, the weld nut 30 is formed with a nut hole 31 connected to the bolt coupling hole 11 of the mounting plate 10, and the weld nut 30 is welded to the lower surface of the mounting plate 10.

As shown in fig. 5, the top of the weld nut 30 is welded to the edge of the bolt engagement hole 11. Herein, the inner diameter of the nut hole 31 of the weld nut 30 is smaller than the inner diameter of the bolt engagement hole 11.

The weld nuts 30 are welded to the lower surface of the mounting plate 10, and fitted into the mounting holes 7 provided in the frame 3. When the second reinforcement surface 15 of the mounting plate 10 contacts the upper surface of the frame 3, the weld nuts 30 can be completely fitted into the mounting holes 7 of the frame 3.

That is, the mounting plate 10 is in contact with the upper surface of the frame 3 through the second reinforcement surface 15, and the weld nuts 30 are inserted into the mounting holes 7. In this state, the mounting plate 10 may be welded to the frame 3.

In the exemplary embodiment, the joining bolt 50 is a fastening member that joins the component assembly 1 to the frame 3 through the mounting plate 10 and the weld nut 30. The engagement bolt 50 penetrates the mounting bracket 5 of the component assembly 1 and engages with the nut hole 31 of the weld nut 30 through the bolt engagement hole 11 of the mounting plate 10.

Here, the coupling bolt 50 may be coupled with the weld nut 30 through the mounting bracket 5 on the upper surface of the frame 3.

An assembly process of the vehicle component mounting unit 100 and a vehicle component mounting method using the vehicle component mounting unit 100 according to an exemplary embodiment will be described in detail below with reference to the drawings.

First, in the exemplary embodiment, at least one mounting hole 7 is machined on an upper surface of frame 3.

The lower surface of the mounting plate 10 is welded with a weld nut 30 formed with a nut hole 31 connected to the bolt coupling hole 11 of the mounting plate 10. That is, the weld nut 30 is welded to the edge of the bolt engagement hole 11 of the lower surface of the mounting plate 10.

With the mounting plate 10 set as described above, the weld nut 30 is inserted into the mounting hole 7. At this time, the weld nuts 30 are inserted into the mounting holes 7 while the second reinforcement surfaces 15 (i.e., the lower surfaces of the mounting plates 10) are in contact with the upper surface of the frame 3.

Next, in the exemplary embodiment, mounting plate 10 is welded to the upper surface of frame 3. In the exemplary embodiment, the edges of slot 17 of mounting plate 10 and frame 3 are welded to each other to form a first weld 21, and the two ends of mounting plate 10 and frame 3 are welded to each other to form a second weld 22.

Here, the mounting bracket 5 is in contact with the first reinforcement surface 13 (i.e., the upper surface of the mounting plate 10). Further, the bolt insertion holes 9 provided in the mounting bracket 5 are aligned with the bolt engagement holes 11 of the mounting plate 10.

Further, the engagement bolt 50 is engaged with the nut hole 31 of the weld nut 30 through the bolt insertion hole 9 of the mounting bracket 5 and the bolt engagement hole 11 of the mounting plate 10.

In the exemplary embodiment, the engagement bolt 50 is engaged with the weld nut 30 from the upper surface of the frame 3 through the bolt insertion hole 9 of the mounting bracket 5 and the bolt engagement hole 11 of the mounting plate 10, and thus the component assembly 1 can be easily mounted on the frame 3.

Based on the vehicle component mounting unit 100 according to the exemplary embodiment, the component assembly 1 may be mounted to the frame 3 by the mounting plate 10 having the weld nut 30 and welded to the square tube 3a of the frame 3.
