Description
[Technical field]
[0001] The present invention relates to a vehicle body including a plurality of shock absorber housings located on the upper ends of respective wheels of an in-wheel platform vehicle, the shock absorber housings supporting and covering the shock absorbers connected to the wheels of the vehicle. [Background technology]
[0002] A vehicle body is required to be designed to mount various internal equipment and to efficiently absorb the impact load and protect vehicle occupants when an impact is applied to the vehicle. Existing vehicles require a space for mounting an engine or a battery, and a space for mounting wheels, suspension, and steering devices for driving the vehicle. Therefore, not only the wheel housings on which each wheel is mounted, but also the suspension devices provided on each wheel, the steering device connecting each wheel, and the drive device for transmitting driving force take up a considerable amount of space in the vehicle body, so this must be taken into consideration when designing the vehicle body, and it must be designed to absorb shocks applied to the vehicle. In addition, the more devices that must be considered, the more complicated the manufacturing and assembly process of the vehicle body becomes and the longer it takes.
[0003] However, in-wheel systems have been developed recently, in which the driving unit, steering unit, reduction unit, etc. are built into the wheels of a vehicle, but unlike existing vehicles, the in-wheel system does not need to be connected to each wheel, so the body must be designed differently from existing vehicles. Therefore, when a vehicle adopts an in-wheel system, it is necessary to develop a body in which each wheel housing space is formed, sufficient rigidity of the body is secured, and the manufacturing and assembly process can be simplified.
[0004] The matters described as the background art are intended to enhance understanding of the background of the present invention only, and should not be construed as corresponding to prior art already known to those skilled in the art. [Prior art documents] [Patent documents]

The vehicle body according to an embodiment of the present invention is a vehicle body including a plurality of shock absorber housings 100 which cover and support shock absorbers connected to wheels of a vehicle, and the shock absorber housings 100 have protruding parts 120 which protrude upward from the lower end of the shock absorber housings 100 and have an internal space therein, and the lower end or protruding parts 120 of the shock absorber housings 100 are coupled to the shock absorbers with the shock absorbers inserted into the internal space of the protruding parts 120.
[0024] In addition, the internal space of the shock absorber housing 100 is formed in a cylindrical shape, and the lower end or protrusion 120 of the shock absorber housing 100 can be coupled to the shock absorber through the side or upper surface of the internal space with the shock absorber inserted into the internal space of the protrusion 120.
[0025] The vehicle body according to an embodiment of the present invention is for a vehicle using an in-wheel system, unlike existing vehicles, and does not require a drive shaft, steering device, etc. to be connected between each wheel. Therefore, each vehicle wheel has a shock absorber at the upper end of the wheel and a shock absorber housing 100, each shock absorber housing 100 has a protruding portion 120 protruding with an internal space, a shock absorber is located in the internal space of the protruding portion 120, and the shock absorber is coupled to and supported by the inner wall of the shock absorber housing 100 in the internal space, so that the shock absorber housing 100 protects the vehicle wheel and the shock absorber at the upper end of the wheel.
[0026] Meanwhile, in the vehicle body according to an embodiment of the present invention, the lower end of the shock absorber housing 100 includes a flange portion 110 having a plurality of flanges spaced apart from one another along the outer circumferential surface of the lower end, and the shock absorber housing 100 may be coupled to the vehicle body member 150 with the vehicle body member 150 inserted into a spaced apart space of the flange portion 110. Also, the shock absorber housing 100 may be coupled to the vehicle body member 150 or the shock absorber through an upper surface, a lower surface, or a side surface of the spaced apart space with the vehicle body member 150 inserted into the spaced apart space of the flange portion 110.
[0027] Specifically, 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 includes a flange portion 110 formed with a plurality of flanges spaced apart from one another, and the space between the flange portion 110 is formed in a U-shape. Various body members 150 of the vehicle are coupled to the space through an open side, and the body member 150 also has an open cross-sectional shape with one side open to fit the space, and is inserted into the space to be coupled to the flange portion 110 of the shock absorber housing 100.
[0028] In addition, the body member 150 has a shape extending in the longitudinal direction, a closed surface is formed at an end, and the closed surface, upper surface, lower surface, or side surface of the body member 150 may be coupled to the flange portion 110 in a surface contact state.

[0029] Specifically, the body member 150 has an open cross-section structure with one side open, since it is inserted into the flange portion 110 and assembled, and when it is coupled to the flange portion 110, it comes into surface contact with the inner surface of the space between the flange portion 110. The body member 150 is coupled to the inner surface of the space between the flange portion 110 by a method such as bolting using a tool inserted through the open side of the body member 150 while being inserted into the space between the flange portion 110. This coupling method allows humans or robots to easily and simply assemble each member in the assembly process while maintaining the rigidity of the vehicle body or the coupling rigidity between the members when the shock absorber housing 100 and the body member 150 are coupled.
[0030] Meanwhile, in a vehicle body according to one embodiment of the present invention, a pillar member 200 that connects the front shock absorber housing and the rear shock absorber housing to form a cabin is attached to the shock absorber housing 100, and the pillar member 200 has an end that is attached to the lower end of the shock absorber housing 100 and an inner surface that is supported or attached to the side wall of the protrusion 120 of the shock absorber housing 100.
[0031] Specifically, the pillar member 200 is bent upward and extends at the side of the vehicle to reinforce the vehicle's side collision rigidity, form a cabin room of the vehicle, and connect each shock absorber housing 100 in the longitudinal direction of the vehicle. The lower end of the pillar member 200 is coupled to the lower end of the shock absorber housing 100 through the space between the flange portion 110, and the inner surface of the pillar member 200 is supported or coupled to the side wall of the protrusion 120, thereby ensuring the coupling rigidity between the pillar member 200 and the shock absorber housing 100 and the rigidity of the vehicle body.
[0032] In addition, in the vehicle body according to an embodiment of the present invention, a support member 140 is coupled to the shock absorber housing 100 for connecting and supporting the shock absorber housing 100 and the pillar member 200, and 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 to have an upper end coupled to a side surface of the pillar member 200. The lower end of the shock absorber housing 100 has a coupling part 130 protruding upward from the lower end, and the lower end of the support member 140 may be supported or coupled to a side surface of the coupling part 130 or an outer surface of the protrusion 120.
[0033] As a result, the pillar member 200 is not only connected at its end to the lower end of the shock absorber housing 100, but also has its inner surface supported by the side wall of the protruding portion 120 of the shock absorber housing 100 that protrudes in an L-shape, so that when an impact is applied to the vehicle body, a larger load can be supported by the protruding portion 120 of the shock absorber housing 100.

[0035] Specifically, the pillar member 200 has a lower end connected to the shock absorber housing 100. Here, the pillar member 200 is more firmly connected to the front and rear by the support members 130, and when a load is applied to the pillar member 200, the load is transferred or distributed to the shock absorber housing 100 and the front or rear lower truss member 210 and the side lower truss member 220, which are connected to the lower end of the shock absorber housing 100 via the support members 130 and reinforce the front, rear and side collision rigidity. Similarly, when a load is applied to the shock absorber housing 100 and the front or rear lower truss member 210 and the side lower truss member 220, the load can be distributed between the respective parts to minimize the impact.
[0036] Fig. 3 is a view showing a vehicle body member and a connecting member being connected to a shock absorber housing of a vehicle body according to an embodiment of the present invention. Fig. 4 is a view showing a vehicle body having four shock absorber housings on both sides of the front and rear of a vehicle according to an embodiment of the present invention. In the vehicle body according to an embodiment of the present invention, a lattice-shaped floor member 410 is provided below the shock absorber housings 100, and each shock absorber housing 100 can be supported on the floor member 410 via a plurality of connecting members 400.

[0038] Meanwhile, the lower end of the shock absorber housing 100 of the vehicle body according to an embodiment of the present invention includes a plurality of corners, and one of the plurality of corners may have a cut-out portion cut to form an obtuse angle. Also, a total of four shock absorber housings 100 may be provided on both sides of the front and rear of the vehicle, and each shock absorber housing 100 may be assembled with the cut-out portion facing the outside of the vehicle.
[0039] Specifically, the shock absorber housing 100 is not manufactured so that the front, rear, or side housings of the vehicle have different shapes, but is manufactured to have a single shape and can be assembled by changing only the direction, which improves manufacturing efficiency and reduces costs. Also, the cut portions of each shock absorber housing 100 are arranged toward the outside of the vehicle, so that a space is provided for the wheels of the in-wheel system to operate normally, the load between members can be supported or the load can be distributed in the direction of each member, and the corners of the shock absorber housing 100 can be prevented from protruding outside the vehicle.
[0040] In addition, the shock absorber housing 100 according to an embodiment of the present invention and each vehicle body member can be connected to each other by bolting.
