Description

TECHNICAL FIELD

[0001] The present invention relates to a vehicle body of a vehicle. BACKGROUND

[0002] Generally, a vehicle body of a vehicle should be designed to allow various components to be installed in the vehicle, and to effectively absorb a collision impact when the collision impact is applied to the vehicle, thereby protecting passengers in the vehicle from the collision impact.

[0003] A conventional vehicle requires a space to install an engine or a battery, and a space to install a wheel for driving the vehicle, a suspension device, a steering device, etc. Therefore, since a wheel cover for accommodating the wheel, a suspension device provided at the wheel, a steering device connecting the wheels to each other, a driving device for providing a driving force, etc. occupy a considerable space, the vehicle body should be designed to provide sufficient space to accommodate the components and absorb an impact applied to the vehicle. In addition, as the number of related components increases, the manufacturing and assembly process of the vehicle body becomes more complicated, and the time required to perform the process also increases.

[0004] In recent years, an in-wheel system in which a driving unit, a steering unit, a reduction gear, etc. are installed has been developed. In the in-wheel system, since it is not necessary to connect each wheel to each other as in the conventional vehicle, the vehicle body should be designed differently from the conventional vehicle. Therefore, when the vehicle adopts the in-wheel system, there is a need to develop a vehicle body capable of providing a space for a wheel cover, sufficiently securing the rigidity of the vehicle body, and simplifying the manufacturing and assembly process of the vehicle body.

[0027] Reference will now be made in detail embodiments of the application, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0028] Figure 1is a view showing a shock absorber housing in a vehicle body of a vehicle according to an embodiment of the present application. Figure 2 is a side view showing a shock absorber housing in a vehicle body of a vehicle according to an embodiment of the present application. Figure 3 is a view showing coupling of a vehicle body member and a connection member in a shock absorber housing of a vehicle body of a vehicle according to an embodiment of the present application. Figure 4 is a view showing that four shock absorber housings are disposed at both sides of a front portion and a rear portion of a vehicle body of a vehicle according to an embodiment of the present application.

[0029] A vehicle body of a vehicle according to an embodiment of the present application includes a plurality of shock absorber housings 100 covering and supporting respective shock absorbers connected to vehicle wheels. Each shock absorber housing 100 includes a protrusion 120 protruding upward from a lower end of the shock absorber housing 100 and having an internal space. The lower end of the shock absorber housing 100 or the protrusion 120 is coupled to a shock absorber in a state in which the shock absorber is disposed in the internal space of the protrusion 120.

[0030] The internal space in the shock absorber housing 100 is configured to have a cylindrical shape, and the lower end of the shock absorber housing 100 or the protrusion 120 can be coupled to the shock absorber in a state in which the shock absorber is disposed in the internal space of the protrusion 120 through a side surface or an upper surface of the internal space.

[0031] Unlike a conventional vehicle, the vehicle body of the vehicle according to an embodiment of the present application is intended to be applied to a vehicle employing an in-wheel system, and does not require a drive shaft or a steering device, etc. to be connected between respective wheels. Accordingly, a shock absorber and the shock absorber housing 100 are disposed in each wheel of the vehicle, which are disposed above the wheel. The shock absorber housing 100 includes a protrusion 120 having an internal space and protruding to be formed such that the shock absorber is located in the internal space of the protrusion 120. Since the shock absorber is disposed in the internal space and is supported and coupled by inner walls of the shock absorber housing 100, the shock absorber housing 100 protects the wheel of the vehicle and the shock absorber disposed above the wheel.

[0032] In the vehicle body of the vehicle according to an embodiment of the present application, a lower end of the shock absorber housing 100 is provided with a flange unit 110 formed along an outer periphery of the lower end of the shock absorber housing 100, the flange unit 110 being composed of a plurality of flanges vertically spaced apart from each other. The shock absorber housing 100 can be coupled to a vehicle body member 150 in a state in which the vehicle body member 150 is fitted into the spaced apart spaces between the flanges of the flange unit 110. In addition, the shock absorber housing 100 can be coupled to the vehicle body member 150 or a shock absorber through an upper surface, a lower surface, or a side surface of the spaced apart spaces of the flange unit 110 in a state in which the vehicle body member 150 is fitted into the spaced apart spaces of the flange unit 110.

[0033] In detail, the shock absorber housing 100 includes a lower end and a protrusion 120 protruding from the lower end. The lower end of the shock absorber housing 100 is provided with a flange unit 110 including a plurality of flanges vertically spaced apart from each other, so that a spaced apart space between the flanges of the flange unit 110 is formed to have a "U" shaped cross section. The shock absorber housing 100 is coupled with various vehicle body members 150 in the spaced apart space through an open side of the flange unit. The vehicle body members 150 are also configured to have an open cross section matching the spaced apart space, and are fitted into the spaced apart space to be coupled to the flange unit 110 of the shock absorber housing 100.

[0034] The vehicle body member 150 is configured to extend in a length direction, and has a closed surface at an end portion thereof. The closed surface, an upper surface, a lower surface, or a side surface of the vehicle body member 150 can be coupled to the flange unit 110 in a surface contact manner. The vehicle body member 150 can be configured to have an internal space and an extended shape, and is open at one surface thereof, whereby the vehicle body member 150 is coupled to the flange unit 110 with a tool introduced into the internal space through the open surface.

[0035] In detail, since the vehicle body member 150 is fitted into the flange unit 110 to be assembled with the flange unit 110, and one surface of the vehicle body member 150 is open to have an open cross section, the inner surface of the vehicle body member 150 is in surface contact with the flange unit in the spaced apart space of the flange unit 110 when the vehicle body member 150 is coupled to the flange unit 110. The vehicle body member 150 is fitted into the spaced apart space of the flange unit 110, and is coupled to the inner surface of the spaced apart space in a manner including bolting with a tool introduced through the open surface of the vehicle body member 150. This coupling method makes it possible to maintain the rigidity of the vehicle itself and the coupling rigidity between the members when the shock absorber housing 100 and the vehicle body member 150 are coupled, and enables a person or a robot to conveniently and easily assemble the members.

[0036] In the vehicle body of the vehicle according to the embodiment of the present application, a pillar member 200 connecting the front shock absorber housing 100 and the rear shock absorber housing 100 to define a passenger compartment is coupled to the shock absorber housing 100. An end portion of the pillar member 200 is coupled to the lower end of the shock absorber housing 100, and is coupled to and supported by the side wall of the protrusion 120 of the shock absorber housing 100 at an inner surface of the pillar member.

[0037] In particular, the pillar member 200 is curved upward at the side of the vehicle and extends to increase the collision rigidity of the vehicle in a side collision and to define a cabin, and connects the respective shock absorber housings 100 to each other in the length direction of the vehicle. The lower end of the pillar member 200 is coupled to the lower end of the shock absorber housing 100. In particular, the pillar member 200 is coupled to the lower end of the shock absorber housing 100 through the spaced space in the flange unit 110, and the inner surface of the pillar member 200 is coupled to and supported by the side wall of the protrusion 120, thereby ensuring the rigidity of the vehicle and the coupling rigidity between the pillar member 200 and the shock absorber housing 100.

[0038] In the vehicle body of the vehicle according to the embodiment of the present application, the support member 140 connecting and supporting the shock absorber housing 100 and the pillar member 200 can be coupled to the shock absorber housing 100. One end of the support member 140 is coupled to one side of the lower end of the shock absorber housing 100 and extends upward. The upper end of the support member 140 is coupled to the side surface of the pillar member 200. The lower end of the shock absorber housing 100 can be provided with a coupling piece 130 protruding upward from the lower end of the shock absorber housing 100, and the lower end of the support member 140 can be coupled to the side surface of the coupling piece 130 or the outer surface of the protrusion 120 and can be supported by the side surface of the coupling piece 130 or the outer surface of the protrusion 120.

[0039] Accordingly, since the pillar member 200 is not only coupled to the lower end of the shock absorber housing 100 at its end portion, but also its inner surface is supported by the side wall of the protrusion 120 of the shock absorber housing 100 having an "L"-shaped cross section and protruding upward, when an impact is applied to the vehicle body, a greater load can be supported by the protrusion 120 of the shock absorber housing 100. In addition, since the support member 140 is coupled to the side surface of the coupling piece 130 or the outer surface of the protrusion 120 provided at the lower end of the shock absorber housing 100 in a surface contact manner, the rigidity of the vehicle body and the coupling rigidity between the members can be sufficiently ensured.

[0040] In the vehicle body of the vehicle according to the embodiment of the present application, a front lower cross member or a rear lower cross member 210 extending downward and curved to connect the front shock absorber housings or the rear shock absorber housings 100 to each other in the width direction of the vehicle, or a side lower cross member 220 extending downward and curved to connect the side shock absorber housings 100 to each other in the length direction of the vehicle can be coupled to the shock absorber housing 100.

[0041] In detail, the lower end of the pillar member 200 is coupled to the shock absorber housing 100. Here, because the pillar member 200 is more firmly coupled to the shock absorber housing 100 in the front-rear direction by the support member 140, when a load is applied to the pillar member 200, the pillar member 200 disperses or transmits the load to the shock absorber housing 100, the front or rear lower cross member 210 coupled to the lower end of the shock absorber housing 100 to increase the collision rigidity in the front-rear and side directions, or the side lower cross member 220 through the support member 140. Similarly, when a load is applied to the shock absorber housing 100, the front or rear lower cross member 210, or the side lower cross member 220, the load is dispersed to the respective members, thereby minimizing the impact caused by the load.

[0042] Figure 3 FIG. 4 is a view illustrating coupling of a vehicle body member and a connection member in a shock absorber housing of a vehicle body according to an embodiment of the present application. Figure 4 FIG. 5 is a view illustrating four shock absorber housings disposed at the front and both sides of the rear of a vehicle body of a vehicle according to an embodiment of the present application. In the vehicle body of the vehicle according to the embodiment of the present application, a plurality of shock absorber housings 100 can be disposed under a grid-shaped floor member 410, and each shock absorber housing 100 can be supported by the floor member 410 through a plurality of connection members 400. The upper end of each connection member 400 can be coupled to the lower surface of the corner portion facing the inside of the vehicle among the corner portions of the shock absorber housing 100, and can extend downward while being inclined to the outside of the shock absorber housing 100, and the lower end thereof is coupled to the upper surface of the floor member 410.

[0043] In detail, the upper end of the connection member 400 can be coupled to the lower surface of the corner portion facing the inside of the vehicle among the plurality of corner portions of the shock absorber housing 100, and can extend downward while being inclined to the outside of the shock absorber housing 100, and the lower end thereof is coupled to the upper surface of the floor member 410. Since the connection member 400 extends while being inclined to the outside of the shock absorber housing 100, the installation space of the wheel located under the shock absorber housing 100 can be maximized. Further, since the upper end of the connection member 400 supports the shock absorber housing 100, the wheel of the in-wheel system vehicle can normally rotate and move under the shock absorber housing 100.

[0044] In the vehicle body of the vehicle according to the embodiment of the present application, the lower end of the shock absorber housing 100 can include a plurality of corner portions, and a cutout portion can be provided in one of the corner portions, the cutout portion being formed to have an obtuse angle. Four shock absorber housings 100 can be disposed at the front and both sides of the rear of the vehicle, and configured such that the cutout portion faces the outside of the vehicle.

[0045] Specifically, since the shock absorber housings 100 located on the sides of the front and rear of the vehicle are manufactured with the same structure instead of different structures, and are installed only in different orientations, manufacturing efficiency can be improved and manufacturing costs reduced. Furthermore, since the cutouts of each shock absorber housing 100 face the outer side of the vehicle to provide space for the normal operation of the wheels of the in-wheel system vehicle, the load between the various components can be supported or the load can be distributed in the direction of the component placement, and the corners of the shock absorber housing 100 can be prevented from protruding outwards from the vehicle exterior.

[0046] According to embodiments of the present invention, the shock absorber housing 100 and the vehicle body components can be connected to each other by bolts. Since the vehicle body components, such as the shock absorber housing 100, are not manufactured with different structures but rather have the same structure and are symmetrically assembled in the vehicle, assembly and vehicle production are facilitated, and assembly rigidity and impact resistance are ensured. Furthermore, since the vehicle body is assembled at the flange unit 110 of the shock absorber housing 100 or at the ends of components with open or closed surfaces using simple methods such as bolts, the assembly process can be conveniently performed by humans or robots in a short time.

[0047] As can be clearly seen from the above description, embodiments of the present invention provide a vehicle body for an in-wheel platform vehicle, which includes a plurality of shock absorber housings located above each wheel of the vehicle, and each shock absorber housing includes a protrusion that projects upward from its lower end and has an internal space, wherein a shock absorber connected to the wheel is disposed in the internal space of the protrusion, thereby connecting the shock absorber housing to the shock absorber and covering and supporting the shock absorber.

[0048] Although preferred embodiments of the invention 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 invention as disclosed in the appended claims.
