Description

Technical Field

[0001] This disclosure relates to a front assembly for a mobile device, a front integrated mobile device including the front assembly, and a method for assembling the front integrated mobile device, wherein the hood, bumper, and fenders are integrally formed into a single component, thereby reducing weight and manufacturing costs, and increasing rigidity, thereby increasing resistance to collisions. Background Technology

[0002] Typically, a hood is located at the front of the vehicle body for opening or closing the engine compartment. Recently, environmentally friendly vehicles, such as electric vehicles, have become widely used. Since electric vehicles do not require an engine, the size of the propulsion system can be reduced. Therefore, part of the engine compartment is used as a front trunk for storing luggage, and a hood is provided to open or close the front trunk.

[0003] Because this hood is constructed such that the brackets mounted on the hood panel and the brackets mounted on the front bulkhead are connected to each other by hinges, the hood can be opened or closed by rotating the hinges and is supported by the vehicle body.

[0004] However, because the hood is made of a high-rigidity steel plate and is assembled to the plate hood with separate hinges, it is difficult to change the hood's structure. Furthermore, because the hood is firmly locked in place by its own weight when closed, it exerts a large impact on the vehicle when the hood is closed.

[0005] Furthermore, the weight of the hood increases due to the various brackets and hinge structures required for its installation. Therefore, traditional hood structures are difficult to apply to environmentally friendly vehicles.

[0006] The details described as background art are intended only to facilitate understanding of the background of this disclosure and should not be construed as an admission of prior art known to those skilled in the art. Summary of the Invention

[0034] In the following description, a front assembly for a mobile device, a front-integrated mobile device including the front assembly, and a method of assembling the front-integrated mobile device according to a preferred embodiment of the present disclosure will be described with reference to the accompanying drawings.

Figure 7 This is a view showing the assembly of a front-integrated mobile device according to an embodiment of the present disclosure. Figure 8 This is a flowchart illustrating a method for assembling a front-integrated mobile device according to an embodiment of the present disclosure. Figure 9 This is a view showing the assembly of a front-integrated mobile device according to an embodiment of the present disclosure. Figure 10 This is a view showing a front-integrated mobile device assembled according to an embodiment of the present disclosure via a bracket.

[0036] like Figures 1 to 3As shown, the front assembly A of the mobile device according to an embodiment of the present disclosure is configured such that the bumper 100, fender 200 and hood 300 constituting the front of the mobile device are integrally formed, the bumper 100 and fender 200 are connected to each other to form an interior space, and the front end of the hood 300 is rotatably connected to the bumper 100 to open or close the interior space by rotating the rear end of the hood 300 in the vertical direction.

[0037] According to an embodiment of the present disclosure, the front assembly A of the mobile device is configured such that the bumper 100, fender 200, and hood 300 are integrally formed, an interior space is formed between the bumper 100 and the fender 200, and the hood 300 can rotate to open or close the interior space. Here, the interior space can be used as an engine compartment or a front trunk.

[0038] In other words, the front component A is configured such that the bumper 100, which absorbs forward impacts and provides an aesthetically pleasing design, and the fender 200 surrounding the wheel are integrally formed to create an interior space, and the hood 300 is connected to the bumper 100 to open or close the interior space, which serves as an engine compartment or trunk.

[0039] The front component A is made of plastic to reduce weight. Therefore, the bumper 100, fender 200 and hood 300 are integrally formed from plastic material by injection molding.

[0040] In the prior art, the bumper 100, fender 200, and hood 300 are manufactured separately and then assembled together by a hinge device, which reduces manufacturing efficiency. However, since the front component A according to this disclosure is configured such that the bumper 100, fender 200, and hood 300 are integrally formed from plastic material, the front component A can be easily manufactured by injection molding.

[0041] As described above, since the bumper 100 and hood 300 constituting the front component A are made of flexible plastic material, the hood 300 can rotate vertically to open or close the interior space by deforming the plastic material.

[0042] Specifically, the hood 300 may consist of an outer panel 310 rotatably connected to the bumper 100 and an inner panel 320 connected to the inner surface of the outer panel 310. The inner panel 320 may be made of a material with higher rigidity than the outer panel 310.

[0043] like Figure 3As shown, the outer panel 310 is integrally connected to the bumper 100 and formed together with the bumper 100. The inner panel 320 is attached to the inner surface of the outer panel 310 to increase the overall rigidity of the hood 300. Here, the inner panel 320 may be made of steel as a rigid material and may be formed to cover the inner surface of the outer panel 310, thereby enhancing the rigidity of the outer panel 310.

[0044] Therefore, the hood 300 allows other components to be easily installed onto the hood 300 via the inner panel 320. Furthermore, since the outer panel 310 is made of a flexible material while the inner panel 320 is made of a rigid material, when an external impact occurs, the outer panel 310 absorbs the external impact while the inner panel 320 supports the impact load, thereby improving the hood 300's ability to resist external collisions.

[0045] The liquid storage tank 400 is mounted to the inner surface of the inner plate 320 via multiple brackets B.

[0046] Because the coolant reservoir 400 is mounted to the inner panel 320 of the hood 300, the space required for housing the coolant reservoir 400 in the interior space is reduced. Multiple coolant reservoirs 400 can be installed depending on the intended use or capacity of the coolant.

[0047] The liquid storage tank 400 can be mounted to the inner plate 320 via the bracket B. The liquid storage tank 400 can be divided into multiple liquid storage tanks, and the rigidity of the inner plate 320 can be increased by connecting the bracket B to the liquid storage tank 400.

[0048] In other words, the liquid storage tank 400 may include a central liquid storage tank 410 and two side liquid storage tanks 420, with the two side liquid storage tanks 420 disposed on both sides of the central liquid storage tank 410, and the central liquid storage tank 410 and the two side liquid storage tanks 420 arranged in the transverse direction on the inner surface of the inner plate 320.

[0049] As described above, the liquid storage tank 400 may include multiple liquid storage tanks, namely a central liquid storage tank 410 disposed in the center of the inner plate 320 and side liquid storage tanks 420 disposed on both sides of the central liquid storage tank 410. Although the central liquid storage tank 410 may also be divided into multiple liquid storage tanks, since the liquid storage tanks 400 are evenly arranged on the inner surface of the inner plate 320 and the intended use and capacity can be met by only providing the central liquid storage tank 410 and the side liquid storage tanks 420, the embodiment of this disclosure provides one central liquid storage tank 410 and two side liquid storage tanks 420.

[0050] Therefore, since the inner panel 320 is provided with a central liquid reservoir 410 and a side liquid reservoir 420 constituting the liquid reservoir 400, and they are arranged at predetermined intervals along the transverse direction of the inner panel 320, the overall rigidity of the hood 300 including the inner panel 320 is increased by the bracket B for connecting the central liquid reservoir 410 and the side liquid reservoir 420 to the inner panel 320.

[0051] like Figure 4 As shown, brackets B are respectively installed at the front end and both sides of the central liquid storage tank 410. The bracket B1 installed at the front end of the central liquid storage tank 410 is located in the center of the central liquid storage tank 410, and the brackets B2 installed at both sides of the central liquid storage tank 410 are symmetrically arranged in the transverse direction.

[0052] As described above, the central liquid storage tank 410, located in the center of the inner plate 320, has supports B at its front end and both sides, allowing the central liquid storage tank 410 to be mounted onto the inner plate 320 via the supports B. Here, since the supports B are located at the front end and both sides of the central liquid storage tank 410, they can absorb impacts occurring at the front of the moving device and increase the connection strength of the central liquid storage tank 410. Although the supports B could also be located at the rear end of the central liquid storage tank 410, since the force caused by the collision is distributed to the side liquid storage tanks 420 located on both sides of the inner plate 320, the supports B can be located only at the front end and both sides of the central liquid storage tank 410.

[0053] like Figure 5 As shown, each side reservoir 420 is provided with multiple supports B at its front end, rear end, inner end, and outer end. The supports B4 and B3 provided at the front end and rear end of the side reservoir 420, and the supports B5 and B6 provided at the inner end and outer end of the side reservoir 420, are arranged to be spaced apart from each other on the outer periphery.

[0054] Since the side liquid storage tank 420 is provided with brackets B at its front end, rear end, inner end and outer end and is connected to the inner plate 320 through each bracket B, the side liquid storage tank 420 can be firmly connected to the inner plate 320.

[0055] In bracket B, brackets B3 and B4, respectively located at the rear and front ends of the side reservoir 420, are spaced apart from each other in a direction inclined relative to the front-rear direction. Similarly, brackets B5 and B6, respectively located at the inner and outer ends of the side reservoir 420, are spaced apart from each other in a direction inclined relative to the lateral direction. In other words, since each side reservoir 420 is securely fixed to the inner plate 320 by multiple brackets B, and since brackets B3 and B4, located at the rear and front ends of the side reservoir 420, are positioned in an inclined direction, and brackets B5 and B6, located at the inner and outer ends of the side reservoir 420, are also positioned in an inclined direction, the impact applied to the inner plate 320 is dispersed.

[0056] Specifically, the bracket B3 located at the rear end of the side liquid storage tank 420 is configured to be spaced outward relative to the bracket B4 located at the front end of the side liquid storage tank 420, while the bracket B5 located at the inner end of the side liquid storage tank 420 is configured to be spaced backward relative to the bracket B6 located at the outer end of the side liquid storage tank 420.

[0057] As described above, since the bracket B3b located at the rear end of the side reservoir 420 is spaced outward relative to the bracket B4 located at the front end of the side reservoir 420, a load path is formed when a collision occurs at the front of the moving device. Through this load path, the impact caused by the collision is transmitted through the central reservoir 410 and from the bracket B4 located at the front end to the bracket B3 located at the rear end.

[0058] Furthermore, since the bracket B5 located at the inner end of the side reservoir 420 is positioned rearward relative to the bracket B6 located at the outer end of the side reservoir 420, a load path is formed when a collision occurs on the side of the moving device. Through this load path, the impact caused by the collision is transmitted from the bracket B6 located at the outer end to the bracket B5 located at the inner end via the central reservoir 410.

[0059] Because the side reservoir 420 is equipped with multiple brackets B, the side reservoir 420 can be securely fixed to the inner panel 320. In addition, since the brackets B are arranged to be spaced apart from each other in the longitudinal and lateral directions to form a load path, the hood 300 is ensured to have sufficient rigidity to resist collisions.

[0060] like Figure 3 As shown, the bumper 100 is provided with a latching unit 500, which is configured to selectively allow the hood 300 to rotate. The latching unit 500 selectively engages with a frame F disposed on the moving device. Figure 7 As shown), front C ( Figure 7 (as shown) or the holder L at the mudguard 200 (as shown) Figure 6 (As shown) Joining.

[0061] In other words, the latch unit 500 can be mounted to the bumper 100. When the hood 300 closes the interior space, the latch unit 500 engages with a retainer L located on the frame F, front bulkhead C, or fender 200 to hold the hood 300 in place, and disengages from the retainer L when the latch unit 500 is operated to allow the hood 300 to be opened.

[0062] The latch unit 500 includes a lever portion 510 disposed at the bumper 100, a line 520 extending from the lever portion 510, and a latch portion 530, the latch portion 530 being connected to the line 520 and being separated from the retainer L by a pulling force generated by the lever portion 510.

[0063] In other words, the latch unit 500 consists of a lever 510, a wire 520, and a latch portion 530. The lever 510 is configured to be movable in the front-rear direction at the bumper 100. When the lever 510 moves forward due to user operation, the wire 520 is pulled, and the latch portion 530 separates from the retainer L, thereby releasing the engagement between the latch portion 500 and the retainer L.

[0064] A latch 530 is located at the rear of the hood 300 and selectively engages or disengages from the retainer L through the interaction of a lever 510 and a line 520. Figure 6 As shown, the latch 530 can be configured to have a pin that engages or disengages from the retainer L according to the tension of the line 520, and the retainer L is provided at the frame F or front enclosure C of the moving device and has a hole therein into which the latch 530 is selectively inserted.

[0065] As described above, the front component A according to an embodiment of the present disclosure is mounted on the frame F of the mobile device, and its latching unit 500 is mounted on the bumper 100, such that the hood 300 selectively closes or opens when the latching unit 500 selectively engages or disengages from the retainer L.

[0066] like Figure 1 and Figure 7 As shown, the mudguard 200 consists of a front mudguard 210 integrally connected to the bumper 100 and a rear mudguard 220 fixed to the frame F of the moving device. The front mudguard 210 and the rear mudguard 220 can be configured to be connected to each other by sliding in the longitudinal direction.

[0067] Therefore, the front fender 210 is shaped to have the entire front portion of the fender 200, and the rear fender 220 is shaped to have the entire rear portion of the fender 200. The front fender 210 is integrally connected to the bumper 100 and the hood 300, and the rear fender 220 is separate from the front fender 210 and fixed to the frame F of the moving device. Therefore, when the front assembly A is mounted on the frame F of the moving device, the front fender 210 is slidably connected to the rear fender 220.

[0068] In other words, since the front fender 210 is provided with a sliding guide structure at the rear end of the front fender 210 and the front end of the rear fender 220, the front fender 210 can be assembled with the rear fender 220 in a sliding guide manner.

[0069] Therefore, the efficiency of assembling the front fender 210 and the rear fender 220 can be improved. In addition, since the front fender 210 is guided and assembled with the rear fender 220, the front component A can be easily connected to the frame F of the mobile device.

[0070] like Figure 7 As shown, the front-integrated mobile device according to an embodiment of the present disclosure includes: a front assembly A configured such that a bumper 100, a front fender 210, and a hood 300 constituting the front of the mobile device are integrally formed, the bumper 100 and the front fender 210 being connected to each other to form an interior space between the bumper 100 and the front fender 210, and the front end of the hood 300 being rotatably connected to the bumper 100 to open or close the interior space by rotating the rear end of the hood 300 in the vertical direction; and a frame F, which is frontally connected to the front assembly A and connected to a front bulkhead C fitted with the hood 300 and a rear fender 220 fitted with the front fender 210.

[0071] In other words, the front component A is configured such that the bumper 100, which is used to absorb the forward impact of the moving device and provide an aesthetic design, and the front fender 210 surrounding the wheel are integrally formed to create an interior space between the bumper 100 and the front fender 210, and the hood 300 is connected to the bumper 100 to open or close the interior space used as an engine compartment or trunk.

[0072] The frame F of the mobile device for mounting the front component A is provided with a front bulkhead C that is fitted to the hood 300 of the front component A and a rear fender 220 that is fitted to the front fender 210. Therefore, when the front component A is mounted on the frame F, the hood 300 is fitted to the front bulkhead C and the front fender 210 is fitted to the rear fender 220, thereby completing the front of the mobile device.

[0073] Here, the front fender 210 and the rear fender 220 are configured such that when the front fender 210 moves rearward, the front fender 210 slides along the rear fender 220 and engages with the rear fender 220.

[0074] In other words, the guide structure is provided at the rear end of the front fender 210 and the front end of the rear fender 220, so that the front fender 210 is slidably guided along the rear fender 220 and assembled with the rear fender 220.

[0075] Therefore, the assembly efficiency between the front fender 210 and the rear fender 220 can be improved. Furthermore, since the front fender 210 is guided along and assembled with the rear fender 220, the front assembly A can be easily connected to the frame F of the moving device.

[0076] The front-integrated mobile device according to embodiments of the present disclosure can be assembled using the following assembly method.

[0077] like Figure 8 As shown, the assembly method of the front integrated mobile device according to an embodiment of the present disclosure includes: a preparation operation S10, in which the hood 300 of the front component A is rotated relative to the bumper 100 to open the interior space; an installation operation S20, in which the front component A is moved to the front of the frame F to assemble the front fender 210 and the rear fender 220, thereby connecting the front component A including the front fender 210 and the rear fender 220 together to the frame F; and a completion operation S30, in which the hood 300 of the front component A is rotated to close the interior space.

[0078] like Figure 9 As shown, in preparation operation S10, with the hood 300 of the front component A rotated to open the interior space, the front component A is mounted onto the frame F of the mobile device. When the hood 300 of the front component A is positioned with the interior space closed, the inner panel 320 may interfere with the frame F or the front bulkhead C mounted on the frame F when the front component A is mounted onto the frame F. Therefore, the hood 300 of the front component A is rotated to open the interior space.

[0079] In preparation operation S10, the front component A is connected via carrier 600 ( Figure 10 (as shown in the diagram) to move, the bracket 600 is configured to be detachably connected to the hood 300 and bumper 100 of the front component A and to be connected to the hood 300 and bumper 100 in the open state to keep the hood 300 open.

[0080] like Figure 7 and Figure 10As shown, the front component A moves via the bracket 600. Since the bracket 600 is connected to the hood 300 and the bumper 100 when the hood 300 is open, the hood 300 can remain in the open position.

[0081] Therefore, the worker can use the bracket 600 to keep the hood 300 of the front component A open and can move the front component A onto the frame F of the mobile device, so that the front component A can be installed onto the frame F of the mobile device.

[0082] Subsequently, in installation operation S20, the front assembly A moves to the front of the frame F to assemble the front fender 210 with the rear fender 220, thereby connecting the front assembly A, including the front fender 210, and the rear fender 220 together to the frame F. At this time, since guide structures are provided at the front fender 210 and the rear fender 220, the front fender 210 slides along the rear fender 220 and assembles with the rear fender 220, thereby making it easy to install the front assembly A onto the frame F of the moving device. Furthermore, since the front assembly A moves linearly to the frame F of the moving device and is installed onto the frame F of the moving device, the front assembly A is simply installed onto the frame F of the moving device.

[0083] After the front component A is installed onto the frame F, a completion operation S30 is performed to rotate the hood 300 of the front component A to close the interior space.

[0084] It is evident from the above description that, since the front assembly for a mobile device, the front integrated mobile device including the front assembly, and the assembly method of the front integrated mobile device according to the present disclosure are configured such that the hood 300, bumper 100, and fender 200 are integrally formed as a single component, the weight of the front assembly is reduced and the manufacturing cost is lowered.

[0085] Furthermore, since the hood 300, bumper 100, and fender 200 are formed as a single unit, the number of seams is reduced, thereby improving the overall appearance. Additionally, the increased rigidity of the hood 300 through the connecting structure of components such as the fluid reservoir 400 enhances its resistance to impacts.

[0086] Although preferred embodiments of the present disclosure have been disclosed for illustrative purposes, those skilled in the art will understand that various modifications, additions, and substitutions are possible without departing from the scope and spirit of the present disclosure as disclosed in the appended claims.
