[0003] In the related art, when the air conditioning duct of the vehicle body is working, condensation often occurs on the outer wall of the duct because the temperature of the cold air in the duct is lower than the temperature in the cab. After the condensation water gathers into strands, it will form a row of water curtains and drip onto the floor of the vehicle body. The condensation water soaks a large area of ​​the floor, resulting in the condensation water on the floor cannot be discharged in time, which is easy to cause large-scale rust on the sheet metal.

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The embodiments of the present invention provide a vehicle body floor structure and a vehicle to solve the problem in the related art that condensed water gathers into strands and drips onto the vehicle body floor, resulting in the condensed water being unable to be discharged from the vehicle body floor in time, which easily causes large-area corrosion of the sheet metal.

[0026] See also Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a vehicle body floor structure, which may include: a bulging floor 1; two side floors 2, in the width direction of the vehicle body, the two side floors 2 are spaced apart and distributed on both sides of the bulging floor 1, and are fixed to the bulging floor 1, wherein the side floor 2 and the bulging floor 1 may be connected by integral molding or welding fixation, and the horizontal plane where the bulging floor 1 is located is higher than the horizontal plane where the two side floors 2 are located, wherein, as Figure 1As shown, the left and right directions of the bulged floor 1 are the width directions of the vehicle body, the front end of the bulged floor 1 is the front of the vehicle body, and the rear end of the bulged floor 1 is the rear of the vehicle body; the two side floors 2 are tilted upward along the front part of the length direction of the vehicle body to form an inclined surface 3, and each of the side floors 2 is provided with at least one water outlet 4 near the bottom end of the inclined surface 3.

[0027] Specifically, the front ends of the two side floors 2 are tilted upward to form an inclined surface 3. Since the friction coefficient of water is relatively small, by utilizing the acceleration when the car starts, condensed water can naturally flow from the front end of the inclined surface 3 to the rear end of the inclined surface 3 and be discharged through the water outlet 4, thereby utilizing the inertia of the car when accelerating, and allowing the accumulated condensed water to be quickly drained from the car body.

[0028] In some optional embodiments, each side floor 2 is provided with a plurality of water holes 4, and the plurality of water holes 4 are spaced apart along the width direction of the vehicle body. Water dripping from the top of the vehicle body slides down through the inclined surface 3 at the front of the side floor 2 under its own gravity to the front of the side floor 2 and is gathered, and is discharged out of the vehicle body through the plurality of water holes 4, thereby improving drainage efficiency and preventing water from accumulating on the side floor 2 for a long time and causing corrosion to the side floor 2. At the same time, since the horizontal height of the bulging floor 1 is higher than the side floors 2 on both sides, during the driving process of the vehicle body, the shaking of the vehicle body itself will cause the water on the bulging floor 1 to be shaken off to the side floors 2 and the inclined surface 3 on both sides thereof, and finally slides down through the plurality of water holes 4 at the front of the side floor 2 under the action of the water's own gravity and is discharged.

[0029] In some optional embodiments, a plurality of water outlet holes 4 may be provided near the bulging floor 1 where the side floor 2 and the inclined surface 3 are close, and the plurality of water outlet holes 4 are spaced apart in the length direction of the vehicle body, so that when the water on the bulging floor 1 slides down to the side floor 2, it is discharged out of the vehicle body as quickly as possible through the plurality of water outlet holes 4 on the inclined surface 3 and the plurality of water outlet holes 4 at the bending point of the side floor 2 and the inclined surface 3. There is no need for all the water to slide down to the bending point of the side floor 2 and the inclined surface 3 and then be discharged, which greatly shortens the water travel path and thereby greatly reduces the degree of water corrosion on the side floor 2.

[0030] In some embodiments, such as Figure 1 and Figure 3 As shown, each of the inclined surfaces 3 is provided with a plurality of reinforcing ribs 5 protruding upward; in the width direction of the vehicle body, the plurality of reinforcing ribs 5 are arranged at intervals, and the length direction of each reinforcing rib 5 is consistent with the inclination direction of the inclined surface 3. Figure 3As shown, when water drops from above the vehicle body fall onto the reinforcing rib 5 and disperse to its two side walls, and continue to slide down along the two side walls, at the same time, the water on the inclined surface 3 will converge with the water on the two side walls of the reinforcing rib 5, and slide along the side walls of the reinforcing rib 5 to the bending part of the side floor 2, and finally be discharged from the water outlet 4. When the vehicle body starts or accelerates, the vehicle body is used to bring inertia to the water on the inclined surface 3, so that the water is drained along the length direction of the reinforcing rib 5, shortening the water's walking path, directly reaching the bending part between the inclined surface 3 and the side floor 2, and discharged from the water outlet 4; when the vehicle body turns left or right, it is avoided that the water on the inclined surface 3 sways around and cannot slide down to the lower end of the inclined surface 3 in time, thereby increasing the corrosion time of the side floor 2. Under the action of the height of the multiple reinforcing ribs 5, the water is well divided and gathered at the side wall of the reinforcing rib 5, and finally drained along the length direction of the reinforcing rib 5 to be discharged. At the same time, the reinforcing rib 5 can also improve the structural strength and collision performance of the side floor 2.

[0031] In some optional embodiments, the rear ends of the plurality of reinforcing ribs 5 can be arranged toward the water outlet 4, so that the water sliding down the side wall of the reinforcing rib 5 flows directly toward the water outlet 4 and is discharged, thereby avoiding the long-term accumulation of water at the bending part of the side floor 2 and the inclined surface 3, which would aggravate the degree of corrosion of the side floor 2.

[0032] In some optional embodiments, the number of the plurality of reinforcing ribs 5 corresponds to the number of the plurality of water outlet holes 4, and each water outlet hole 4 is located at the rear end of the corresponding reinforcing rib 5, so that after the water slides down along the length direction of the reinforcing rib 5, it is directly discharged from the water outlet hole 4 behind it, thereby avoiding the problem of water accumulating at the bending part of the inclined surface 3 and the side floor 2 and unable to be discharged in time.

[0033] In some embodiments, such as Figure 2 and Figure 3 As shown, each of the side floors 2 is provided with two water diversion grooves 6 at the bottom end near the inclined surface 3, and the two water diversion grooves 6 are both connected to the water outlet 4. The water sliding down from the inclined surface 3 and the water drained from the side wall of the reinforcing rib 5 are collected at the bend between the side floor 2 and the inclined surface 3, and flow into the two water diversion grooves 6 to accumulate, and cannot flow into the rear of the side floor 2, and finally flow from the water diversion groove 6 to the water outlet 4 for discharge, so as to avoid the problem that the water accumulates at the bend between the side floor 2 and the inclined surface 3, and shakes in the front-back direction, causing large-area corrosion.

[0034] In some embodiments, such as Figure 2 and Figure 3As shown, in the width direction of the vehicle body, the two water diversion grooves 6 are spaced apart and distributed on both sides of the water outlet 4, and the length direction of each water diversion groove 6 is consistent with the width direction of the vehicle body; in the direction where each water diversion groove 6 approaches the water outlet 4, the depth of the water diversion groove 6 gradually becomes deeper. Among them, the length direction of the water diversion groove 6 is consistent with the width direction of the vehicle body. Extending the distance of the water diversion groove 6 in the width direction of the vehicle body can block most of the water, so that when the water flows to the lower end of the inclined surface 3, it can enter the two water diversion grooves 6 and gather. When the vehicle body rotates to the right or left, the inertia of the vehicle body is used to divert the water in the water diversion groove 6 into the connected water outlet 4; further, the depth of the water diversion groove 6 gradually becomes deeper in the direction close to the water outlet 4, and the water's own gravity is used to accelerate the flow rate of water, so that the water can be quickly discharged from the vehicle body, which greatly reduces the residence time of water on the side floor 2, thereby reducing the corrosion degree of the side floor 2.

[0035] In some optional embodiments, the angle between the two water diversion grooves 6 can be set to an acute angle, with the opening of the acute angle facing the front end of the side floor 2, so that the water on the inclined surface 3 directly enters the water diversion groove 6 on the way down, and is finally discharged from the water outlet 4, avoiding the problem that the water has to travel the length of the inclined surface 3 to the bend of the side floor 2 and then be discharged through the water diversion groove 6 at the bend, thereby greatly shortening the water's travel distance and reducing the corrosion area of ​​the side floor 2.

[0036] To sum up, the water diversion groove 6 is equivalent to the reinforcing rib protruding downward from the side floor 2 to form a water diversion groove 6. On the one hand, it is convenient for the collection and discharge of water. On the other hand, on the basis of the reinforcing rib 5, it further improves the structural strength of the side floor 2, and has better collision performance and crushing energy absorption effect.

[0037] In some embodiments, such as Figure 4As shown, the bulged floor 1 is provided with a plurality of reinforcing ribs 7 protruding upward, and in the width direction of the vehicle body, the plurality of the reinforcing ribs 7 are arranged at intervals, and the plurality of the reinforcing ribs 7 are roughly distributed in a light scattering shape, and the scattering direction is toward the rear end of the bulged floor 1, wherein the plurality of reinforcing ribs 7 divide the water on the bulged floor 1, and when the vehicle body turns left or right, the shaking impact force of the water on the bulged floor 1 over a large area is reduced, and the corrosion of the components above the bulged floor 1 or the front or rear end thereof caused by splashing water is avoided; the bulged floor 1 is also provided with a reinforcing rib 3 8 protruding upward, and in the length direction of the vehicle body, the reinforcing rib 3 8 is located behind the plurality of the reinforcing ribs 7, and the length direction of the reinforcing rib 3 8 is consistent with the width direction of the vehicle body. When water drops onto the bulging floor 1, the outer side walls of the leftmost and rightmost reinforcing ribs 2 7 will directly drain the water to the bends of the side floors 2 on both sides, and collect and drain the water to the water outlet 4 through the water diversion groove 1 6 on the side floors 2, so as to be discharged out of the vehicle body, shortening the water travel path; and the multiple reinforcing ribs 2 7 located in the middle will drain the water to the left and right sides of the vehicle body, and drain the water to the part between the two ends of the reinforcing rib 3 8 behind it for blocking, and finally flow to the two ends of the reinforcing rib 3 8 when the vehicle body is accelerated. Thereby, the water is drained to the bends of the side floors 2 on both sides, and finally collected and discharged to the water outlet 4 through the water diversion groove 6 on the side floor 2, and thus discharged out of the vehicle body; the plurality of reinforcing ribs 2 7 form a scattering structure, which can shorten the travel distance of water, and the reinforcing ribs 3 8 can block the water from flowing to the rear of the bulged floor 1, thereby avoiding large-scale corrosion of the bulged floor 1 and achieving drainage to the side floors 2 on both sides; at the same time, the reinforcing ribs 2 7 and the reinforcing ribs 3 8 can greatly improve the structural strength of the bulged floor 1, and can also achieve the purpose of drainage and discharge.

[0038] In some optional embodiments, such as Figure 1 and Figure 5 As shown, the length direction of the plurality of reinforcing ribs 2 7 can also be consistent with the length direction of the vehicle body, and can also drain the water on the bulging floor 1, and quickly drain it in strands along the side walls of the reinforcing ribs 2 7 to the reinforcing ribs 3 8, and then be discharged to the side floors 2 on both sides.

[0039] In some embodiments, such as Figure 1 and Figure 5As shown, the reinforcing rib 3 8 is arranged in an arch shape, and the convex direction of the reinforcing rib 3 8 is toward the front end of the bulging floor 1. Among them, the reinforcing rib 3 8 is arranged in an arch shape, which can reduce the impact force of water sliding down along the reinforcing rib 2 7, and prevent the water from splashing onto the parts above the bulging floor 1 and the rear of the bulging floor 1 after hitting the reinforcing rib 3 8, so that the water can flow along the length direction of the reinforcing rib 3 8 to the side floor 2 on both sides for discharge. Even if the vehicle body is not accelerated, the water can flow along the length direction of the reinforcing rib 3 8 to the side floor 2 on both sides for discharge under its own gravity.

[0040] In some optional embodiments, the second reinforcing rib 7 may be omitted, and only the third reinforcing rib 8 may be provided, and the third reinforcing rib 8 is provided in an arched shape. When the vehicle body accelerates, water flows from the front of the bulging floor 1 to the third reinforcing rib 8 over a large area, and is blocked by the third reinforcing rib 8 and flows to the side floors 2 on both sides for discharge, which can also achieve the purpose of discharging water on the bulging floor 1.

[0041] In some optional embodiments, the two ends of the reinforcing rib three 8 can be located in front of the two water outlet holes 4 or in the middle of the two water outlet holes 4, so that when water is discharged from the two ends of the reinforcing rib three 8 to the two side floors 2, it flows into the water channel one 6 and is quickly discharged out of the vehicle body.

[0042] In some optional embodiments, such as Figure 5 As shown, the two ends of the reinforcing rib 3 8 can also be located behind the two water outlets 4, but at least one reinforcing rib 4 (not shown in the figure) is arranged behind the two water outlets 4 along the length direction of the vehicle body, and the reinforcing rib 4 can block the water discharged from the two ends of the reinforcing rib 3 8, so as to prevent the sliding water from corroding the rightmost end of the right side floor 2 and the leftmost end of the left side floor 2, thereby reducing the water splashing area. At the same time, when the vehicle body slows down, the sliding rainwater is drained along the side wall of the reinforcing rib 4 to the two water diversion grooves 6 in front of it for discharge. Similarly, the reinforcing rib 4 further improves the structural strength of the side floor 2.

[0043] Furthermore, the reinforcing rib 4 can be set to an obtuse angle structure, and the opening of the obtuse angle faces one end of the reinforcing rib 3 8, so that the water discharged from the two ends of the reinforcing rib 3 8 will be collected in the two inner side walls between the obtuse angles of the reinforcing rib 4, thereby avoiding corrosion to the rear part of the side floor 2 and reducing the corrosion area of ​​the rear part of the side floor 2. At the same time, when the vehicle body accelerates, when part of the water on the side floor 2 flows to the reinforcing rib 4, the rear end of the reinforcing rib 4 set at an obtuse angle can block the water, reducing the corrosion area of ​​the rear part of the side floor 2 by water.

[0044] In some embodiments, the bulging floor 1 is provided with a plurality of reinforcing ribs 2 7 protruding upwards. In the width direction of the vehicle body, the plurality of reinforcing ribs 2 7 are arranged at intervals. The plurality of reinforcing ribs 2 7 are distributed roughly in a light scattering shape, and the scattering direction is toward the rear end of the bulging floor 1; the bulging floor 1 is provided with a water diversion groove 2, which is arranged behind the plurality of reinforcing ribs 2 7, and the length direction of the water diversion groove 2 is consistent with the width direction of the vehicle body. Among them, it is equivalent to forming a reinforcing rib protruding below the bulging floor 1 to form a water diversion groove 2, so that when the water is drained through the reinforcing ribs 2 7, it will be collected in the water diversion groove 2 behind it, and finally the acceleration of the vehicle body when accelerating is used to drain the water in the water diversion groove 2 to the side floors 2 on both sides, and drain from the water diversion groove 1 6 on the side floors 2, and then discharged from the water outlet 4, so as to realize the drainage work on the bulging floor 1.

[0045] In some embodiments, the depth of the water diversion groove 2 gradually increases from the middle to the two ends. In the case of utilizing the acceleration of the vehicle body, further utilizing the height difference change of the water diversion groove 2, the water discharge speed is accelerated under the action of the gravity of the water, thereby shortening the residence time of the water on the bulging floor 1 and reducing the corrosion effect on the bulging floor 1.

[0046] In some optional embodiments, the water diversion channel 2 may also be arranged in an arch shape, with the arch protruding in the direction toward the front end of the vehicle body, and can also utilize the speed of water sliding backwards to gently turn and quickly flow out to the side floors 2 on both sides.

[0047] In some embodiments, a water guide shield 9 is installed in each of the water outlet holes 4, and a spiral channel 10 is provided at the water outlet end of the water guide shield 9. The water guide shield 9 can be made of a flexible material, specifically, a nylon material, and is embedded and installed at the water outlet hole 4, which can reduce the degree of collision between the water guide shield 9 and the water outlet hole 4, thereby reducing the abnormal noise caused by the vehicle body when driving; further, the lower end of the water guide shield 9 is connected with a spiral channel 10 to achieve one-way discharge of water, avoid the airflow under the side floor 2 affecting the water discharge efficiency of the water outlet hole 4 when the vehicle is driving, and ensure the air tightness of the vehicle body, reducing the noise from the bottom of the floor; avoid the problem that when the opening of the vehicle body floor is not blocked, the water outlet hole 4 will destroy the air tightness of the vehicle body, and the air tightness of the vehicle body has a greater impact on the characteristics such as vehicle noise.

[0048] In some embodiments, an embodiment of the present invention provides a vehicle, which may include a vehicle body floor structure as described in the above embodiments.

[0049] Among them, Figure 1As shown, the vehicle body floor structure may include: a bulging floor 1; two side floors 2, in the width direction of the vehicle body, the two side floors 2 are spaced apart and distributed on both sides of the bulging floor 1, and are fixed to the bulging floor 1, wherein the side floors 2 and the bulging floor 1 may be welded or integrally stamped, and the horizontal plane where the bulging floor 1 is located is higher than the horizontal plane where the two side floors 2 are located, wherein, as Figure 1 As shown, the left and right directions of the bulged floor 1 are the width directions of the vehicle body, the front end of the bulged floor 1 is the front of the vehicle body, and the rear end of the bulged floor 1 is the rear of the vehicle body; the two side floors 2 are tilted upward along the front part of the length direction of the vehicle body to form an inclined surface 3, and each of the side floors 2 is provided with at least one water outlet 4 near the bottom end of the inclined surface 3.

[0050] Specifically, the front ends of the two side floors 2 are tilted upward to form an inclined surface 3. Since the friction coefficient of water is relatively small, by utilizing the acceleration when the car starts, condensed water can naturally flow from the front end of the inclined surface 3 to the rear end of the inclined surface 3 and be discharged through the water outlet 4, thereby utilizing the inertia of the car when accelerating, and allowing the accumulated condensed water to be quickly drained from the car body.

[0051] In some embodiments, such as Figure 1 and Figure 3 As shown, each of the inclined surfaces 3 is provided with a plurality of reinforcing ribs 5 protruding upward; in the width direction of the vehicle body, the plurality of reinforcing ribs 5 are arranged at intervals, and the length direction of each reinforcing rib 5 is consistent with the inclination direction of the inclined surface 3. Figure 3 As shown, when water drops from above the vehicle body fall onto the reinforcing rib 5 and disperse to its two side walls, and continue to slide down along the two side walls, at the same time, the water on the inclined surface 3 will converge with the water on the two side walls of the reinforcing rib 5, and slide along the side walls of the reinforcing rib 5 to the bending part of the side floor 2, and finally be discharged from the water outlet 4. When the vehicle body starts or accelerates, the vehicle body is used to bring inertia to the water on the inclined surface 3, so that the water is drained along the length direction of the reinforcing rib 5, shortening the water's walking path, directly reaching the bending part between the inclined surface 3 and the side floor 2, and discharged from the water outlet 4; when the vehicle body turns left or right, it is avoided that the water on the inclined surface 3 sways around and cannot slide down to the lower end of the inclined surface 3 in time, thereby increasing the corrosion time of the side floor 2. Under the action of the height of the multiple reinforcing ribs 5, the water is well divided and gathered at the side wall of the reinforcing rib 5, and finally drained along the length direction of the reinforcing rib 5 to be discharged. At the same time, the reinforcing rib 5 can also improve the structural strength and collision performance of the side floor 2.

[0052] In some embodiments, such as Figure 2 and Figure 3As shown, each of the side floors 2 is provided with two water diversion grooves 6 at the bottom end near the inclined surface 3, and the two water diversion grooves 6 are both connected to the water outlet 4. The water sliding down from the inclined surface 3 and the water drained from the side wall of the reinforcing rib 5 are collected at the bend between the side floor 2 and the inclined surface 3, and flow into the two water diversion grooves 6 to accumulate, and cannot flow into the rear of the side floor 2, and finally flow from the water diversion groove 6 to the water outlet 4 for discharge, so as to avoid the problem that the water accumulates at the bend between the side floor 2 and the inclined surface 3, and shakes in the front-back direction, causing large-area corrosion.

[0053] In some embodiments, such as Figure 2 and Figure 3 As shown, in the width direction of the vehicle body, the two water diversion grooves 6 are spaced apart and distributed on both sides of the water outlet 4, and the length direction of each water diversion groove 6 is consistent with the width direction of the vehicle body; in the direction where each water diversion groove 6 approaches the water outlet 4, the depth of the water diversion groove 6 gradually becomes deeper. Among them, the length direction of the water diversion groove 6 is consistent with the width direction of the vehicle body. Extending the distance of the water diversion groove 6 in the width direction of the vehicle body can block most of the water, so that when the water flows to the lower end of the inclined surface 3, it can enter the two water diversion grooves 6 and gather. When the vehicle body rotates to the right or left, the inertia of the vehicle body is used to divert the water in the water diversion groove 6 into the connected water outlet 4; further, the depth of the water diversion groove 6 gradually becomes deeper in the direction close to the water outlet 4, and the water's own gravity is used to accelerate the flow rate of water, so that the water can be quickly discharged from the vehicle body, which greatly reduces the residence time of water on the side floor 2, thereby reducing the corrosion degree of the side floor 2.

[0054] In some embodiments, a water guide shield 9 is installed in each of the water outlet holes 4, and a spiral channel 10 is provided at the water outlet end of the water guide shield 9. The water guide shield 9 can be made of a flexible material, specifically, a nylon material, and is embedded and installed at the water outlet hole 4, which can reduce the degree of collision between the water guide shield 9 and the water outlet hole 4, thereby reducing the abnormal noise caused by the vehicle body when driving; further, the lower end of the water guide shield 9 is connected with a spiral channel 10 to achieve one-way discharge of water, avoid the airflow under the side floor 2 affecting the water discharge efficiency of the water outlet hole 4 when the vehicle is driving, and ensure the air tightness of the vehicle body, reducing the noise from the bottom of the floor; avoid the problem that when the opening of the vehicle body floor is not blocked, the water outlet hole 4 will destroy the air tightness of the vehicle body, and the air tightness of the vehicle body has a greater impact on the characteristics such as vehicle noise.

[0055] In summary, the setting of the reinforcing ribs improves the structural strength of the vehicle body floor, while diverting the water on the vehicle body floor, accelerating the rapid discharge of water in the vehicle body floor, thereby reducing the degree of corrosion to the vehicle body floor; at the same time, the setting of the water-guiding shield 9 and the spiral channel 10 thereon, on the one hand, plays a sealing role, which can prevent rainwater and wind and sand from entering the cockpit, and at the same time ensure the air tightness of the vehicle body floor.
