Abstract

Claims (38)

1. A chassis cab vehicle comprising:

a lower frame, which constitutes a lower structure of the chassis cab vehicle and is equipped with a pair of side members extending in a lengthwise direction of the chassis cab vehicle;

a battery coupled between the side members; and

an upper body, which is coupled to a front portion of the lower frame to form a cabin interior,

wherein a side sill is formed at a lower end at each side of the upper body and extends to a rear of the cabin interior,

wherein the side sills overlap the respective side members in a lateral direction of the chassis cab vehicle when coupled to the lower frame,

wherein the upper body includes a plurality of upper cross members configured to connect both of the side sills extending to the rear of the cabin interior,

wherein a plurality of middle cross members is configured to connect both of the side members to each other and formed in the central portion of the lower frame, and

wherein the plurality of middle cross members overlaps at least one of the plurality of upper cross members.

2. The chassis cab vehicle of claim 1 , wherein:

the lower frame includes a front lower frame, a central lower frame, and a rear lower frame based on a front-rear direction of the chassis cab vehicle; and

each side sill extends from the rear of the cabin interior to a central portion of the lower frame.

3. The chassis cab vehicle of claim 2 , wherein the lower frame is shaped such that a width of the lower frame decreases from the rear lower frame to the front lower frame.

4. The chassis cab vehicle of claim 2 , wherein the central portion of the lower frame is recessed downward, and wherein both end portions of the central lower frame are bent outward to extend and connect to the front lower frame and the rear lower frame.

5. The chassis cab vehicle of claim 1 , wherein the side sills overlap the respective side members in the lateral direction of the chassis cab vehicle and the upper body is fixed by a plurality of fixing parts.

6. The chassis cab vehicle of claim 5 , wherein:

the plurality of fixing parts is provided on the lower frame and includes a first mounting part, a second mounting part, and a third mounting part; and

the first mounting part, the second mounting part, and the third mounting part are disposed spaced apart from each other in the lengthwise direction of the vehicle.

7. The chassis cab vehicle of claim 6 , wherein:

the side sills are spaced apart from the respective side members in the lateral direction of the vehicle so that a gap space is formed between each side sill and the respective side member; and

the second mounting parts and the third mounting parts are disposed in the gap spaces connecting the upper body to the respective side members.

8. The chassis cab vehicle of claim 6 , wherein the first mounting parts, the second mounting parts, and the third mounting parts are disposed to prevent a battery from being displaced in the lateral direction.

9. The chassis cab vehicle of claim 6 , wherein the first mounting parts and the second mounting parts are provided on a front portion of the lower frame whereby the upper body and the side members are coupled at each side of the chassis cab vehicle.

10. The chassis cab vehicle of claim 6 , wherein the third mounting parts are provided on the central portion of the lower frame whereby a rear end portion of the side sills and the respective side members are coupled at each side of the chassis cab vehicle.

11. The chassis cab vehicle of claim 1 , wherein the upper body is coupled to the lower frame so that the side sills, the plurality of upper cross members, and the plurality of middle cross member are interconnected to form a load path for a side collision of the chassis cab vehicle.

12. The chassis cab vehicle of claim 1 , wherein the plurality of upper cross members and the plurality of middle cross members are formed in parallel with each other.

13. The chassis cab vehicle of claim 1 , wherein an open space is formed at the rear of the cabin interior to connect a loading body capable of loading an object.

14. A chassis cab vehicle comprising:

a lower frame, which constitutes a lower structure of the chassis cab vehicle and is equipped with a pair of side members extending in a lengthwise direction of the chassis cab vehicle;

a battery coupled between the side members; and

an upper body, which is coupled to a front portion of the lower frame to form a cabin interior, wherein a side sill is formed at a lower end at each side of the upper body and extends to a rear of the cabin interior, and wherein the side sills overlap the respective side members in a lateral direction of the chassis cab vehicle when coupled to the lower frame,

wherein the side sills overlap the respective side members in the lateral direction of the chassis cab vehicle and the upper body is fixed by a plurality of fixing parts,

wherein

i) the plurality of fixing parts is provided on the lower frame and includes a first mounting part, a second mounting part, and a third mounting part, and

ii) the first mounting part, the second mounting part, and the third mounting part are disposed spaced apart from each other in the lengthwise direction of the vehicle, and

wherein

i) the side sills are spaced apart from the respective side members in the lateral direction of the vehicle so that a gap space is formed between each side sill and the respective side member, and

ii) the second mounting parts and the third mounting parts are disposed in the gap spaces connecting the upper body to the respective side members.
