[0003] The present invention relates to a moving structure for replaceable parts of a vehicle. More specifically, the present invention relates to such a moving structure and a moving system for replaceable parts that can replace replaceable parts that can be changed according to the usage purpose of the vehicle. Background art

[0004] Recently, the vehicle industry has been introducing new concepts of future mobility visions to realize people - centered dynamic future cities. One of these future mobility solutions is a purpose - based vehicle (PBV) customized on demand as a motor vehicle.

[0005] PBV can be an example of an environment - friendly mobile vehicle based on an electric vehicle (EV). These PBVs can provide various customized services for users.

[0006] The body of the PBV has an upper body assembled to the lower body. The upper body can be manufactured in various shapes according to the type of customized service provided to the user.

[0007] However, if the structure of the upper body is developed separately according to the type of customized service provided to the user as described above, the production cost may increase.

[0008] Therefore, recently, PBVs have been developed that can improve vehicle utilization while reducing production costs.

[0009] For example, a vehicle is being developed that has a common configuration for the front part (including the driver's seat) of the upper body and the lower body, and a configuration for the rear part of the upper body that can be changed according to the user's purpose.

[0010] Here, the front part of the vehicle can be defined as a fixed part (fixed portion) fixed to the front part of the lower body. In addition, the rear part of the vehicle can be defined as a replaceable part (replaceable portion) manufactured in various shapes according to the intended use of the vehicle.

[0011] The fixed part is a part that is not replaced even if the intended use of the vehicle changes. And, the replaceable part is a part that can be replaced according to the intended use of the vehicle, can be combined with the fixed part and the rear part of the lower body, or can be separated from the fixed part and the rear part of the lower body.

[0012] To this end, the automotive industry is working on exploring a replaceable component exchange solution that can easily replace replaceable components according to the intended use of the vehicle.

[0013] The statements in this background section are only for enhancing the understanding of the background of the present disclosure and may include matters other than conventional techniques known to those of ordinary skill in the art. Summary of the Invention

[0156] The fixed component 11 of the vehicle 10 is fixed to the front part of the lower body 1, and the replaceable component 12 is connected to the fixed component 11 and the rear part of the lower body 1 through the joint unit 15.

[0157] Such a vehicle 10 can be a network car or a high-roof car each including a carriage on the fixed component 11 and the replaceable component 12.

[0158] In addition, the vehicle 10 can be a delivery truck with a carriage formed on the fixed component 11 and a luggage compartment formed on the replaceable component 12.

[0159] Alternatively, the vehicle 10 can be a pickup truck or a flatbed trailer with a carriage formed on the fixed component 11 and a deck formed on the replaceable component 12.

[0160] As described above, the replaceable component 12 of the vehicle 10 can be replaced at a field workshop through the replaceable component replacement system 20.

[0161] For this purpose, the vehicle 10 enters the station frame 110 and positions itself at a set position within the station frame 110.

[0162] Next, the connection between the fixed component 11 and the replaceable component 12 through the joint unit 15 is released, and the connection between the lower body 1 and the replaceable component 12 is released.

[0163] As Figure 11 shown, the slider 55 of the body docking engagement member 57 connected with the replaceable component guiding unit 50 moves forward along the track block 53 on the lower body 1.

[0164] That is, the slider 55 compresses the elastic part 61 between the stopper 59 and the body docking engagement member 57 and is in a state of moving forward.

[0165] And, the replaceable component docking engagement member 30 connected to the replaceable component 12 is docked and connected to the body docking engagement member 57 (see FIG. 6 and Figure 11 ).

[0166] The docking protrusion 67 of the body docking handle 63 of the body docking engagement member 57 is docked and connected in the vertical direction to the docking hole 35 of the replaceable component docking handle 31 of the replaceable component docking engagement member 30.

[0167] The drive gear module 130 is moved downward by the lifting unit 150 to a position corresponding to the rack 70 of the replaceable part 12 (see Figure 9A and Figure 10A ).

[0168] In this state, the drive gear module 130 is moved upward by the lifting unit 150 (see Figure 10B ).

[0169] When the lifting drive servo motor 151 of the lifting unit 150 operates, the lead screw 153 threadedly connected to the bottom plate 131 rotates. Accordingly, as the bottom plate 131 moves upward along the guide rod 157, the entire drive gear module 130 can move upward.

[0170] When the drive gear module 130 moves upward, the pinion 135 of the drive gear module 130 engages with the rack 70 of the replaceable part 12 (see Figure 9B and Figure 10C ).

[0171] Next, as shown in Figure 10C , the gear drive servo motor 133 of the drive gear module 130 operates. Then, the pinion 135 rotates in one direction, and causes the replaceable part 12 to move backward from the fixed part 11 via the rack 70 (see Figure 10D ).

[0172] During this process, as shown in Figure 12 , the slider 55 moves backward along the track block 53. At this time, the elastic portion 61 compressed between the stopper 59 and the vehicle body docking engagement member 57 is released.

[0173] Since the replaceable part docking engagement member 30 connected to the replaceable part 12 and the vehicle body docking engagement member 57 connected to the slider 55 are docked and connected, the replaceable part 12 moves backward from the fixed part 11 along the track block 53 through the slider 55.

[0174] In this state, the replaceable part 12 is lifted upward from the lower vehicle body 1 by the replaceable part transfer device 21, as shown in Figure 13 . Accordingly, the replaceable part docking engagement member 30 and the vehicle body docking engagement member 57 are separated from each other in the vertical direction, thereby releasing their docking connection.

[0175] The replaceable part 12 lifted by the replaceable part transfer device 21 moves to a predetermined position.

[0176] The replaceable part transfer device 21 loads another separately supplied replaceable part 12 onto a predetermined position on the lower vehicle body 1.

[0177] The docking joint member 30 of the replaceable part is docked and connected to the docking joint member 57 of the vehicle body in the vertical direction, as Figure 13 shown.

[0178] At this time, as Figure 9A shown, the drive gear module 130 is moved downward by the lifting unit 150 to a position corresponding to the rack 70 of another replaceable part 12.

[0179] Next, as Figure 9B shown, the drive gear module 130 is moved upward by the lifting unit 150.

[0180] To explain the downward movement of the drive gear module 130 above, when the lifting drive servo motor 151 of the lifting unit 150 operates, the lead screw 153 threadedly connected to the bottom plate 131 rotates in the other direction. Therefore, as the bottom plate 131 moves downward along the guide rod 157, the entire drive gear module 130 can move downward.

[0181] When the drive gear module 130 moves upward as described above, the pinion 135 meshes with the rack 70 of another replaceable part 12. Then, when the gear drive servo motor 133 of the drive gear module 130 operates, the pinion 135 rotates in the reverse direction and moves another replaceable part 12 forward toward the fixed part 11 through the rack 70.

[0182] Here, as Figure 11 shown, the slider 55 connected to the docking joint member 57 of the vehicle body moves forward along the track block 53 on the lower vehicle body 1.

[0183] In this state, another replaceable part 12 can be connected to the rear part of the lower vehicle body 1 and the fixed part 11 through the joint unit 15.

[0184] The moving structure 100 for replaceable parts and the replaceable part moving system 200 according to the embodiments described so far can move the replaceable part 12 in the front-rear direction, so that the replaceable part 12 that can be changed according to the intended use of the vehicle 10 can be easily replaced on-site.

[0185] Therefore, with the moving structure 100 for replaceable parts and the replaceable part moving system 200 according to the embodiments, the replaceable part 12 can be replaced without disturbing the surrounding parts.

[0186] Therefore, the moving structure 100 for replaceable parts and the replaceable part moving system 200 according to the embodiments can improve the replaceability operation of the replaceable part 12, contribute to the standardization of the replaceable part replacement solution, and ensure a competitive advantage.

[0187] Although the embodiments of the present invention have been described above, the present invention is not limited thereto, and various modifications can be made within the scope of the claims, the detailed description of the present invention, and the appended drawings, and these modifications also fall within the scope of the present invention.
