[0021] 3. The setting of the interval between the upper end of the front longitudinal reinforcement bar and the upper end of the rear longitudinal reinforcement bar avoids the reduction of the height of the available space at the door position of the mining single-row pickup cab, making it easier for people to get on and off the vehicle from the door position;

[0023] 5.

At the same time, the reinforcement frame is fixedly installed on the bottom of the cab of the mining single-row pickup truck through a mounting seat, so that the reinforcement frame can be applied to the modification of existing vehicles, and at the same time, the connection between the parts in the reinforcement frame has a higher structural strength;

[0024] 6. The setting of the top heightened protective cover can expand the internal longitudinal space of the single-row mining pickup cab;

[0025] 7. The setting of the shielding plate can be used to cover the gap between the top of the vehicle cab and the top heightened protective cover, thereby improving the overall aesthetics.

[0030] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0031] Example 1

[0032] like Figure 1 , Figure 2 As shown, a occupant protection device for a single-row mining pickup truck is installed on the cab of the single-row mining pickup truck after cutting the top part of the roof of the cab of the single-row mining pickup truck, and includes a reinforcement frame 1 and a top heightened protective cover 2. The reinforcement frame 1 includes two side reinforcements, a rear reinforcement is fixedly provided between the rear ends of the two side reinforcements, a front reinforcement is fixedly provided between the front ends of the two side reinforcements, and a top reinforcement 3 with an annular structure is fixedly provided between the upper ends of the two side reinforcements.

[0033] The side reinforcement member includes a bottom reinforcement rod 4 distributed toward the front and rear of the cab, a rear longitudinal reinforcement rod 5 is fixedly connected to the rear end of the bottom reinforcement rod 4, the lower end of the rear longitudinal reinforcement rod 5 protrudes downward relative to the bottom reinforcement rod 4, the front end of the bottom reinforcement rod 4 is bent and extended downward, and the lower end of the rear longitudinal reinforcement rod 5 and the front end of the bottom reinforcement rod 4 are fixedly connected to a mounting seat 6, which is a flange. A front longitudinal reinforcement rod 7 is fixedly provided near the front end of the bottom reinforcement rod 4, the upper end of the front longitudinal reinforcement rod 7 is bent and extended toward the rear longitudinal reinforcement rod 5, the upper end of the rear longitudinal reinforcement rod 5 is bent and extended toward the upper end of the front longitudinal reinforcement rod 7, the upper end of the front longitudinal reinforcement rod 7 and the upper end of the rear longitudinal reinforcement rod 5 are arranged facing each other and there is a gap between them, and the setting of the gap between the upper end of the front longitudinal reinforcement rod 7 and the upper end of the rear longitudinal reinforcement rod 5 avoids the height of the available space at the door position of the mining single-row pickup cab being reduced, which is convenient for people to get on and off the vehicle from the door position.

[0034] The front end of the bottom reinforcement rod 4 is bent downward and extended to be fixedly provided with a mounting seat 6, and the bottom of the front longitudinal reinforcement rod 7 is fixed on the bottom reinforcement rod 4, so that the bottom reinforcement rod 4 can be used to bear the weight and impact force of the front longitudinal reinforcement rod 7. Compared with directly setting the mounting seat 6 at the bottom of the front longitudinal reinforcement rod 7, and the bottom reinforcement rod 4 is only used to connect the front longitudinal reinforcement rod 7 and the rear longitudinal reinforcement rod 5, the front end of the bottom reinforcement rod 4 is bent downward and extended to be fixedly provided with the mounting seat 6, and the bottom of the front longitudinal reinforcement rod 7 is fixed on the bottom reinforcement rod 4. The structural strength is better.

[0035] The front longitudinal reinforcing rod 7 includes, from bottom to top, a first vertical section 8, a first curved section 9, a second curved section 10, a second vertical section 11, a third curved section 12, and a connecting section 13, which are fixedly connected in sequence. The first curved section 9 is bent toward the rear end of the reinforcing frame 1, and the bending direction of the second curved section 10 is opposite to that of the first curved section 9. The bending center angles of the first curved section 9 and the second curved section 10 are both 90°, and the third curved section 12 is bent toward the rear end of the reinforcing frame 1. The structural design of the front longitudinal reinforcing rod 7 can reduce the degree of reduction of the leg space inside the cab, that is, expand the leg space when the reinforcing frame 1 is installed in the cab.

[0036] The rear longitudinal reinforcing rod 5 is divided into four sections from bottom to top, namely, lower, middle, upper and top sections. The lower section is a vertical structure, the middle section and the upper section gradually incline toward the inner side of the reinforcing frame 1, and the inclination angle of the upper section is greater than that of the middle section. The top section bends and extends toward the upper end of the front longitudinal reinforcing rod 7.

[0037] The front reinforcement member includes a transverse connecting rod 14 whose two ends are respectively fixedly connected to the two bottom reinforcement rods 4. The middle section of the transverse connecting rod 14 is an arched structure that arches upward and crosses the center control position of the vehicle, so that the control of the center control position of the vehicle is not affected. The transverse connecting rod 14 gradually tilts from bottom to top toward the rear end of the reinforcement frame 1. A supporting middle beam 15 is fixedly connected to the middle position of the upper end of the arched structure. The upper section of the supporting middle beam 15 is fixedly connected to the top reinforcement member 3. The supporting middle beam 15 bends from bottom to top toward the rear end of the reinforcement frame 1.

[0038] The rear reinforcement includes a rear cross beam 16 whose two ends are fixedly connected to the two rear longitudinal reinforcement rods 5 respectively, and a rear stop portion 17 with an inverted U-shaped structure is fixedly connected to the rear cross beam 16. The lower half of the rear stop portion 17 is a vertical structure, and the upper half gradually tilts toward the front end of the reinforcement frame 1. The upper end of the rear stop portion 17 is fixedly connected to the top reinforcement 3.

[0039] Through structural design, the front longitudinal reinforcing rod 7, the supporting middle beam 15 and other structures near the upper end of the reinforcing frame 1 are all curved arc structures, which can improve the longitudinal force performance of the reinforcing frame 1. At the same time, the structural features of the rear longitudinal reinforcing rod 5, the front longitudinal reinforcing rod 7, the front reinforcement, and the rear stop 17 make the reinforcing frame 1 present a stable structure with a small upper end and a large lower end, which improves the stability of the reinforcing frame 1 and further improves the longitudinal force performance of the strong frame, which is equivalent to improving the structural strength and safety performance of the present invention.

[0040] The top section of the rear longitudinal reinforcement rod 5, the connecting section 13 of the front longitudinal reinforcement rod 7, the upper end of the supporting middle beam 15, and the upper end of the rear stop portion 17 are all fixedly provided with a connecting plate 18, and a through hole is provided on the connecting plate 18. The connecting plate 18 and the top reinforcement 3 are fixedly connected by bolts that penetrate the through holes and are screwed to the top reinforcement 3.

[0041] A ring-shaped shielding plate 19 is welded and fixed on the inner side of the top reinforcement 3, and the top heightened protective cover 2 is sleeved outside the shielding plate 19 and fixedly connected to the shielding plate 19 by bolts. The top heightened protective cover 2 is located on the top of the cab of the single-row mining pickup truck.

[0042] In the actual installation process, it is necessary to cut a window on the top of the existing single-row pickup cab for passing the baffle plate 19, and then set the top heightened protective cover 2 above the window, and then fix the baffle plate 19 and the top heightened protective cover 2 with bolts. At this time, the baffle plate 19 can be used to block the gap between the top of the single-row pickup cab and the top heightened protective cover 2, improving the overall aesthetics of the interior of the cab. At the same time, the setting of the baffle plate 19 can also better fix the top heightened protective cover 2. In actual use, because a window is cut on the top of the cab, and the top reinforcement 3 and the baffle plate 19 are both annular structures, the top heightened protective cover 2 is connected to the internal space of the single-row pickup cab, thereby achieving the effect of expanding the longitudinal space inside the cab.

[0043] The bottom reinforcing rod 4, the rear longitudinal reinforcing rod 5, the front longitudinal reinforcing rod 7, the top reinforcing member 3, the transverse connecting rod 14, the supporting middle beam 15, the rear cross beam 16, and the rear stop 17 are all made of seamless steel pipes. The seamless steel pipe itself has a high structural strength, which can improve the structural strength of the present invention. At the same time, the seamless steel pipe is a hollow structure, and the overall weight is lighter than that of a solid structure, which is conducive to reducing the weight of the present invention.

[0044] The lower section of the rear stop 17 is welded and fixed to the rear cross beam 16, and the lower end of the supporting middle beam 15 is welded and fixed to the transverse connecting rod 14. The bottom reinforcing rod 4 and the transverse connecting rod 14, the bottom reinforcing rod 4 and the front longitudinal reinforcing rod 7, the bottom reinforcing rod 4 and the rear longitudinal reinforcing rod 5, and the rear longitudinal reinforcing rod 5 and the rear cross beam 16 are all detachably fixed. Two mutually perpendicular connecting columns 20 are welded and fixed to the bottom reinforcing rod 4, and two mutually perpendicular connecting columns 20 are also welded and fixed to the rear longitudinal reinforcing rod 5. The connecting columns 20 are also made of seamless steel pipes. The rear end of the bottom reinforcing rod 4, the two ends of the transverse connecting rod 14, the two ends of the rear cross beam 16, and the hollow parts of the connecting columns 20 are filled and welded with solid steel blocks. The outer end of the connecting column 20 is cut with a notch to form a first connecting block 21. The rear end of the bottom reinforcing rod 4, the two ends of the transverse connecting rod 14, and the two ends of the rear cross beam 16 are cut with a notch to form a second connecting block 22. The first connecting block 21 and the second connecting block 22 are assembled to form a cylindrical structure, such as Figure 3 As shown, the first connection block 21 is provided with a screw hole 23 that passes through the first connection block 21, and the second connection block 22 is provided with a countersunk hole 24 that passes through the second connection block 22 and can be aligned with the screw hole 23. The thickness of the second connection block 22 is greater than the thickness of the first connection block 21 and the depth of the screw hole 23 is equal to the depth of the lower half of the countersunk hole 24. A bolt that passes through the countersunk hole 24 and is screwed to the screw hole 23 is provided between the first connection block 21 and the corresponding second connection block 22. The above-mentioned structure makes the first connection block 21 and the second connection block 22 actually have the same thickness as the bolt screwed part, so that the force between the first connection block 21 and the second connection block 22 is more balanced. The solid block makes the first connection block 21 and the second connection a solid structure, which can enhance the structural strength of the position.

[0045] In the present invention, the connection between the seamless tubes of the reinforcement frame 1 is that some seamless tubes are welded to form a whole, and some seamless tubes are connected by bolts through the first connection block 21 and the second connection block 22, and the top section of the rear longitudinal reinforcement rod 5, the connection section 13 of the front longitudinal reinforcement rod 7, the upper end of the supporting middle beam 15, and the upper end of the rear stop 17 are fixedly provided with a connection plate 18, and the connection plate 18 is fixedly connected to the top reinforcement member 3 by bolts. The various components of the present invention are detachably connected, and the reinforcement frame 1 is fixedly installed on the bottom of the cab of the mining single-row pickup truck through the mounting seat 6, so that the present invention can be used for the modification of existing vehicles.

[0046] It should be understood that in the claims and description of the present invention, all "including..." should be understood as an open-ended meaning, that is, its meaning is equivalent to "at least contains...", and should not be understood as a closed meaning, that is, its meaning should not be understood as "only includes...".
