[0042] Next, the embodiments of the present application are described in detail.

[0043] In related technologies, the passenger compartment and cargo box of non-load-bearing pickup trucks are separated, leaving a gap between them. This results in poor side aesthetics, poor cargo box stability, and low crashworthiness. Furthermore, the frame and body of non-load-bearing pickup trucks are typically connected by a flexible connection, resulting in poor torsional rigidity, low safety performance, and reduced ride comfort.

[0044] In view of this, the present application provides a non-load-bearing pickup truck that can improve torsional stiffness and collision safety.

[0045] As shown in FIG1 , the present application provides a non-load-bearing pickup truck, comprising a frame 100 and a body 200 connected to the frame 100. In the present application, the front-to-back direction refers to the length direction of the body, the inside-out direction refers to the width direction of the body, and the up-down direction refers to the height direction of the body.

[0046] 4 to 6 , the vehicle frame 100 includes a pair of opposed frame longitudinal rails 110 and a plurality of frame cross rails 120 disposed between the pair of frame longitudinal rails 110. The plurality of frame cross rails 120 include a first cross rail 121, a second cross rail 122, a third cross rail 123, a fourth cross rail 124, a fifth cross rail 125, and a sixth cross rail 126, which are arranged in parallel and spaced apart from each other from front to rear. Each frame cross rail 120 is connected to the pair of frame longitudinal rails 110 at both ends.

[0047] Specifically, in the present application, both ends of the first cross-member 121 are disposed at the front end surfaces 1010 of the pair of frame rails 110, and both ends of the sixth cross-member 126 are disposed at the rear end surfaces 1030 of the pair of frame rails 110. Thus, the first cross-member 121 encloses the front ends of the pair of frame rails 110, and the sixth cross-member 126 encloses the rear ends of the pair of frame rails 110. The first cross-member 121, the sixth cross-member 126, and the pair of frame rails 110 collectively form a closed frame structure, which enhances the overall rigidity of the vehicle, reduces deformation during bending, improves torsional resistance, and improves the vehicle's handling and driving stability.

[0048] The vehicle body 200 includes a passenger compartment 210, a cargo box 220 located behind the passenger compartment 210, and an engine compartment 230 located in front of the passenger compartment 210. The vehicle frame 100 includes a front frame section 101 connected to the engine compartment 230, a mid-frame section 102 connected to the passenger compartment 210, and a rear frame section 103 connected to the cargo box 220. Frame longitudinal rails 110 extend from the front frame section 101 to the rear frame section 103. A first cross-member 121 is located in the front frame section 101, a second cross-member 122, a third cross-member 123, and a fourth cross-member 124 are located in the mid-frame section 102, and a fifth cross-member 125 and a sixth cross-member 126 are located in the rear frame section 103. The fifth cross-member 125 divides the rear frame section 103 into two sections.

[0049] Thus, the pair of frame longitudinal beams 110, the first cross beam 121, and the second cross beam 122 collectively form the front frame section 101. The pair of frame longitudinal beams 110, the second cross beam 122, and the fourth cross beam 124 collectively form the middle frame section 102. The pair of frame longitudinal beams 110, the fourth cross beam 124, and the sixth cross beam 126 collectively form the rear frame section 103. The front frame section 101, the middle frame section 102, and the rear frame section 103 all have a frame-shaped structure. The front frame section 101, the middle frame section 102, and the rear frame section 103 are distributed along the length of the frame 100 and are sequentially connected.

[0050] The combination of frame longitudinal rails 110 and frame crossbars 120 divides frame 110 into three connected sections: front, middle, and rear. This allows for a more rational design and layout of the overall space of frame 100 to accommodate the varying functional requirements of each section, enhancing the vehicle's flexibility and versatility. Furthermore, the closed frame structures of front section 101, middle section 102, and rear section 103 effectively enhance the overall rigidity of frame 100, effectively dispersing and absorbing torsional and impact forces, and improving the vehicle's torsional and collision resistance.

[0051] Furthermore, the front frame section 101 and the rear frame section 103 are both positioned higher than the middle frame section 102, with the rear frame section 103 positioned higher than the front frame section 101, enabling the vehicle to adapt to complex road conditions. Both the front and rear sections of the frame rail 110 are positioned inwardly, relative to the middle section of the frame rail 110, in the vehicle body's width direction. This indentation enhances the pickup truck's stability and handling. Furthermore, the first cross member 121 is located below the front end 1010 of the frame rail 110, and the middle portion of the sixth cross member 126 is recessed downwardly to accommodate the overall vehicle configuration.

[0052] As shown in FIG5 , the vehicle frame 100 further includes a first connecting beam 130 and a second connecting beam 140 located in the midsection 102 of the vehicle frame. The first connecting beam 130 is longitudinally disposed, with its ends respectively connected to the second crossbeam 122 and the third crossbeam 123. The connection point between the first connecting beam 130 and the second crossbeam 122 is offset from the midpoint of the second crossbeam 122, and the connection point between the first connecting beam 130 and the third crossbeam 123 is offset from the midpoint of the third crossbeam 123.

[0053] Thus, the first connecting beam 130 divides the space enclosed by the pair of frame rails 110, the second crossbeam 122, and the third crossbeam 123 into two areas of unequal size. The frame rails 110, the second crossbeam 122, the first connecting beam 130, and the third crossbeam 123 on one side collectively form a battery pack storage area 1021. The larger of the two areas is battery pack storage area 1021, accommodating the pickup truck's battery pack; the smaller area is used to accommodate the routing of the fuel lines.

[0054] Second connecting beam 140 is disposed transversely, with its ends connecting first connecting beam 130 to the other side of the frame longitudinal rail 110. The connection point between first connecting beam 130 and second connecting beam 140 is near the midpoint of first connecting beam 130. The provision of second connecting beam 140 provides support for first connecting beam 130, making frame 100 more secure and stable.

[0055] 1 , the vehicle body 200 includes a passenger compartment 210, a cargo box 220, and an engine compartment 230. The engine compartment 230 is located in front of and integrally formed with the passenger compartment 210, and the cargo box 220 is located in the rear of and integrally formed with the passenger compartment 210.

[0056] 7 to 9 , the passenger compartment 210 includes a floor 211, a seat cross member 212, a door sill 213, and a dash panel 216. The floor 211 is laid on the bottom of the passenger compartment 210, and the seat cross member 212 is mounted on the floor 211. In other words, the floor 211 is disposed between the seat cross member 212 and the vehicle frame 100.

[0057] The seat cross beam 212 includes, arranged from front to back, a first seat cross beam 2122, a second seat cross beam 2123, a third seat cross beam 2124, and a fourth seat cross beam 2125. The first seat cross beam 2122 and the second seat cross beam 2123 are positioned close together for mounting the front row seats, while the third seat cross beam 2124 and the fourth seat cross beam 2125 are positioned close together for mounting the rear row seats.

[0058] A pair of door sills 213 are respectively provided on both sides of the floor 211 and extend longitudinally. A dash panel 216 is located at the front end of the passenger compartment 210 and separates the engine compartment 230 from the passenger compartment 210. The dash panel 216 is located above the second cross member 122.

[0059] The cargo box 220 is equipped with a top side rail 221 and several spaced-apart cross beams. These cross beams are located at the bottom of the cargo box 220 and include a first cross beam 222, a second cross beam 223, and a third cross beam 224, spaced and arranged in parallel. The first cross beam 222 is located behind the fourth cross beam 124. The second cross beam 223 is located directly above the fifth cross beam 125. The third cross beam 224 is located at the rearmost end of the cargo box 220 and directly above the sixth cross beam 126.

[0060] A pair of front pillars 231 are provided at the front end of the engine compartment 230 , and the front pillars 231 are provided at the front end of the vehicle body 200 .

[0061] Referring to Figures 3, 10, and 11, a pair of pillars 214 and a rear panel 215 are provided at the rear of the passenger compartment 210. The rear panel 215 is connected to the pair of pillars 214 at each end, and the rear panel 215 separates the passenger compartment 210 from the cargo box 220. A pair of roof rails 221 are located on either side of the cargo box 220 and extend longitudinally. The pillars 214, roof rails 221, and rear panel 215 are connected to form a single body, integrating the passenger compartment 210 and the cargo box 220.

[0062] Specifically, the rear panel 215 includes a rear upper cross member 2151. The height of the rear upper cross member 2151 is substantially the same as that of the upper side rail 221. The upper side rail 221 includes an upper side rail inner plate 2211 and an upper side rail outer plate 2212. The upper side rail outer plate 2212 is connected to the pillar 214. The upper side rail inner plate 2211 is connected to the rear upper cross member 2151.

[0063] In the present application, the connection between the pillar 214, the upper side rail 221 and the rear panel 215 is fixed by welding, which is stable, easy to operate and low-cost. The pillar 214 is arranged near the cargo box 220. When the pickup truck is provided with a row of seats, the passenger compartment 210 includes an A-pillar and a B-pillar. In this case, the pillar 214 is a B-pillar. When the pickup truck is provided with two rows of seats, the passenger compartment 210 includes an A-pillar, a B-pillar and a C-pillar. In this case, the pillar 214 is a C-pillar. In the illustrated embodiment, the pickup truck is provided with two rows of seats, and the pillar 214 is a C-pillar.

[0064] The non-load-bearing pickup truck of the present application strengthens the connection between the passenger compartment 210 and the cargo box 220 by connecting the passenger compartment 210 and the cargo box 220 into one. On the one hand, it makes the appearance of the pickup truck without obvious gaps, improves the aesthetics and overall modality of the body 200, simplifies the manufacturing process, and reduces costs; on the other hand, it forms a stronger and tighter connection between the passenger compartment 210 and the cargo box 220, improves the connection stability of the cargo box 220 and the collision safety and handling stability of the body 200.

[0065] The vehicle frame 100 and the vehicle body 200 are provided with a number of hard connection points, and the hard connection points realize a hard connection between the vehicle body 200 and the frame 100 by cooperating with a number of fasteners 300. A hard connection (Rigid Connection) refers to a connection between two or more mechanical parts in a rigid manner so that relative movement between them cannot occur. A flexible connection (Flexible Connection) refers to a connection between two or more mechanical parts in a flexible manner so that a certain degree of relative movement between them is allowed. In the present application, the fastener 300 is a combination of a bolt and a nut. It can be understood that the hard connection points between the frame 100 and the vehicle body 200 are corresponding openings provided in the two, and the openings cooperate with the bolts and nuts to realize a fastened hard connection between the frame 100 and the vehicle body 200.

[0066] The fasteners 300 include an upper fastener 310 and a lower fastener 320. The upper fastener 310 is threaded downward, while the lower fastener 320 is threaded upward. The lower fastener 320 is longer than the upper fastener 310. The front frame section 101, the middle frame section 102, and the rear frame section 103 are all rigidly connected to the vehicle body 200 via the fasteners 300.

[0067] Furthermore, as shown in FIG7 , the front frame section 101 is secured to the engine compartment 230 via fasteners 300. A hard connection point 401 is provided between the bottom of the front end column 231 and the frame rail 110. The front end of the frame rail 110 is hard-connected to the bottom of the front end column 231 via fasteners 300. Specifically, an outwardly protruding platform-type mounting plate 115 is provided at the front end of the frame rail 110. The mounting plate 115 is connected to the front end column 231 via lower fasteners 320. Three lower fasteners 320 are provided between the front end column 231 and the frame rail 110 on each side. There are six hard connection points 401 between the front end column 231 and the frame rail 110.

[0068] The mid-frame section 102 is secured to the passenger compartment 210 via fasteners 300. The dash panel 216 is positioned above the second cross member 122. A hard connection point 402 is provided between the bottom end of the dash panel 216 and the second cross member 122. The bottom end of the dash panel 216 is hard-connected to the second cross member 122 via lower fasteners 320. Specifically, there are two hard connection points 402 and two lower fasteners 320 between the dash panel 216 and the second cross member 122.

[0069] A hard connection point 403 is provided between the midsection of the seat cross member 212 and the floor panel 211 and the frame rail 110. The floor panel 211 and both ends of the seat cross member 212 are hard-connected to the top of the frame rail 110 via upper fasteners 310. As shown in FIG2 , each seat cross member 212 is provided with longitudinally protruding fixing portions 2121 at both ends. These fixing portions 2121 are adapted to receive the upper fasteners 310. In this manner, the upper fasteners 310 sequentially pass through the fixing portions 2121, the floor panel 211, and the frame 100 to secure the seat cross member 212 to the frame 100.

[0070] Referring also to Figure 9 , both ends of the first, second, and third seat cross beams 2122, 2123, and 2124 are provided with both forwardly and rearwardly protruding fixing portions 2121. The fourth seat cross beam 2125 is provided with only forwardly protruding fixing portions 2121 at both ends. In other words, in this embodiment, fourteen hard connection points 403 are provided between the seat cross beams 212 and the frame rails 110, and the four seat cross beams 212 are secured to the frame rails 110 via fourteen upper fasteners 310.

[0071] As shown in FIG7 , a plurality of spaced-apart hard connection points 404 are provided between the door sill 213 and the frame rail 110. The door sill 213 is hard-connected to the bottom of the frame rail 110 via lower fasteners 320. Specifically, ten lower fasteners 320 are provided between the door sill 213 and the frame rail 110 on each side. The total number of hard connection points 404 between the door sill 213 and the frame rail 110 is twenty.

[0072] Furthermore, as shown in Figures 5, 12, and 13, the frame rail 110 includes a main portion 111 and a connecting portion 112. The main portion 111 is longitudinally arranged and extends from the front frame section 101 to the rear frame section 103. The connecting portion 112 protrudes outward from the main portion 111 along the width direction of the vehicle body 200 and is located at the bottom of the frame rail 110. In the longitudinal direction of the vehicle body 200, the connecting portion 112 extends from the second cross member 122 to a position between the third cross member 123 and the fourth cross member 124.

[0073] The main body 111 or the connecting portion 112 is provided with a fastener 300 fixed to the vehicle body 200. In this application, the floor 211 and the seat crossbar 212 are fixed to the main body 111 by upper fasteners 310, and the door sill 213 is fixed to the connecting portion 112 by lower fasteners 320.
