The front collision is one of the main traffic accident forms of passenger cars, the driving area of the passenger car is low, the space of the front protective structure of the passenger car is small, and the weight of the passenger car is generally large when the front collision occurs, particularly the local collision at the side of a driver. The huge deformation of the vehicle body can be caused by the huge kinetic energy generated by collision, so that the activity space of a driver is compressed rapidly, and particularly, the steering wheel collapsed along with the backward deformation of the vehicle body often causes fatal damage to the internal organs of the driver, and threatens the life safety of the driver.

Based on this, the inventor of the present application has conducted intensive research and designed a safety protection device to solve the problem that when an existing automobile is collided, a steering wheel in front of a driver is easily collided with the driver, so that the life safety of the driver is threatened.

Fig. 1 is a schematic structural view of a safety device according to an embodiment of the present application.

An embodiment of the present application provides a safety protection device, as shown in fig. 1, installed in a cab (not shown in the figure), including a sliding rail 100, a sliding bracket 200 and a driver seat 300, where the sliding rail 100 is disposed along a first direction X, and the sliding rail 100 is fixedly connected to a floor (not shown in the figure) of the cab. The sliding bracket 200 has a first end 210 and a second end 220 opposite to each other along the second direction Y, the first end 210 is connected to the sliding rail 100 in a sliding manner along the first direction X, a slope 230 is disposed on a side of the second end 220 departing from the first end 210, the slope 230 and the sliding rail 100 are disposed at a first angle, and the first angle is an acute angle.

The driver seat 300 is disposed above the first end portion 210 of the sliding bracket 200, wherein the sliding bracket 200 is configured to be able to slide along the first direction X relative to the sliding rail 100 under the action of a preset impact force applied to the inclined surface 230 and along the second direction Y. The first direction X and the second direction Y are perpendicular to each other, specifically, the first direction X is parallel to the width direction of the vehicle body, and the second direction Y is parallel to the length direction of the vehicle body.

Thus, when the inclined plane 230 is impacted, the impact force generates a component force along the first direction X, and the component force drives the sliding bracket 200 to drive the driver seat 300 to slide along the sliding rail 100, so as to drive the driver to move away from the steering wheel in front of the driver seat in the first direction X. Thereby avoided taking place the striking between steering wheel and the driver, and then protected driver's life safety, finally improved when present car receives the collision, the easy striking that takes place between steering wheel in the driver place ahead and the driver causes the problem of threat to driver's life safety.

It should be noted that, according to the analysis of the related data, when the automobile is collided, the collision area of the offset collision is smaller than that of the frontal collision, so that the casualties caused by the offset collision are more serious than those caused by the frontal collision. It can be understood that, when the automobile is subjected to offset collision, the impact force generates a component force along the first direction X by means of the inclined plane 230, the component force drives the sliding support 200 to drive the driver seat 300 to slide along the sliding rail 100, meanwhile, the deformation of the automobile caused by collision is continuously increased, so that the sliding support 200 continuously moves along the first direction X, finally, the driver completely laterally moves to one side of the steering wheel, the backward collapsed automobile body structure and the steering wheel are avoided, further, the collision between the steering wheel and the driver is avoided, and finally, the life safety of the driver is protected.

Fig. 2 is a schematic partial structural view of a safety shield apparatus according to an embodiment of the present application.

In some embodiments, as shown in fig. 1 and fig. 2, the cab has a door (not shown) close to the driver's seat 300, and the safety protection device further includes a limiting member 400, wherein the limiting member 400 is disposed through the sliding rail 100 along a third direction Y, specifically, the third direction Y is parallel to the height direction of the vehicle body. And is limited on the side of the sliding bracket 200 facing away from the vehicle door, the limiting member 400 is configured to be broken under the action of a preset impact force applied to the inclined surface 230 and along the second direction Z, so that the sliding bracket 200 can slide relative to the sliding rail along the first direction X towards the side facing away from the vehicle door.

That is to say, when the automobile is not collided, the limiting member 400 can limit the sliding bracket 200, so as to prevent the sliding bracket 200 from driving the driver seat 300 to move, thereby avoiding influencing the normal work of the driver. When the automobile is collided, the component force generated by the impact force on the inclined surface 230 is transmitted to the limiting member 400 through the sliding bracket 200, and the limiting member 400 has limited structural strength, and the component force exceeds the load force that the limiting member 400 can bear, so that the limiting member 400 is broken, and the sliding bracket 200 cannot be limited. The sliding bracket 200 slides along the first direction X relative to the sliding rail under the driving of the component force, so as to drive the driver seat to be away from the steering wheel, thereby protecting the safety of the driver.

In particular, in some embodiments, the safety shield apparatus further includes a sliding block 500 connected to the sliding bracket 200, the sliding rail 100 has a sliding slot 110, and the sliding block 500 is slidably connected to the sliding slot 110. In this way, the sliding bracket 200 is slidably connected to the sliding rail 100 by means of the slider 500, so that the sliding bracket 200 can slide on the sliding rail 100.

Further, a third connecting hole 520 is formed in the slider 500 along the third direction Z, a fourth connecting hole 120 is formed in the slide rail 100 along the third direction Z, and one end of the limiting member 400 is fixed to the bottom side of the slide rail 100. The other end is sequentially inserted through the third connecting hole 520 and the fourth connecting hole 120 and extends out of the sliding slot 110 to abut against one side of the sliding support 200 departing from the vehicle door. Thus, the slide rail 100 and the slider 500 are connected through the limiting member 400, and one end of the limiting member 400 abuts against the sliding bracket 200 to fix the sliding bracket 200. The limiting member 400 includes a bolt, and the specific design is not limited herein.

Further, the safety protection device further includes a ball (not shown in the figure) disposed in the sliding groove 110, and the ball is disposed between the inner wall of the sliding rail 100 and the sliding block 500, so that the friction between the sliding block 500 and the inner wall of the sliding rail 100 is reduced by the ball, the sliding speed of the sliding block 500 is increased, the sliding speed of the driver seat 300 is further increased, and the safety protection for the driver is increased.

In some embodiments, the safety device further includes a connecting member 600, the sliding bracket 200 is provided with a first connecting hole 240, the sliding block 500 is provided with a second connecting hole 510, and the connecting member 600 is inserted into the first connecting hole 240 and the second connecting hole 510 to connect the sliding bracket 200 and the sliding block 500. Thus, the sliding bracket 200 and the sliding block 500 are connected by the connecting member 600, so that the sliding block 500 drives the sliding bracket 200 to slide along the sliding rail 100. Optionally, the connector 600 comprises a bolt. In other embodiments, the sliding bracket 200 and the sliding block 500 are welded to each other, and the specific design may be flexibly changed according to the actual situation, which is not limited herein.

In some embodiments, as shown in fig. 1 and 3, the sliding bracket 200 includes a first connecting rod 250, and a second connecting rod 260 and a third connecting rod 270 disposed at intervals along the first direction X and extending along the second direction Y, and both the second connecting rod 260 and the third connecting rod 270 are slidably connected to the sliding rail 100 along the first direction X. The same ends of the second link 260 and the third link 270 along the second direction Y have intervals along the second direction Y, and are respectively connected to two longitudinal ends of the first link 250, so that the inclined surface 230 is formed on the first link 250.

It can be understood that the same end of the second connecting rod 260 and the third connecting rod 270 along the second direction Y has a spacing along the second direction Y, that is, the distance from the end of the second connecting rod 260 away from the slide rail 100 to the slide rail 100 is not equal to the distance from the end of the third connecting rod 270 away from the slide rail 100 to the slide rail 100. Thus, the first connecting rod 250 and the sliding rail 100 are disposed at a first angle, so that the first connecting rod 250 forms a slope 230.

In particular, in some embodiments, the sliding bracket 200 further includes a reinforcing bar 280, and both ends of the reinforcing bar 280 are connected to the second connecting bar 260 and the third connecting bar 270, respectively. The second and third connecting

bars

260 and 270 are connected by the reinforcing bar 280 to improve the structural strength of the sliding bracket 200 and prevent the sliding bracket 200 from being deformed when being struck. For example, the two ends of the reinforcing bar 280 are welded to the second connecting rod 260 and the third connecting rod 270, and the specific design may be flexibly changed according to practical situations, which is not limited herein.

Further, in order to further improve the structural strength of the sliding bracket 200, a plurality of reinforcing rods 280 are provided, the plurality of reinforcing rods 280 are arranged in parallel and at intervals along the second direction Y, and both ends of each reinforcing rod 280 are respectively connected to the second connecting rod 260 and the third connecting rod 270.

In some embodiments, the sliding bracket 200 further includes a reinforcing beam 290, the reinforcing beam 290 extends along the inclined plane 230 and covers the inclined plane 230, and specifically, the reinforcing beam 290 is provided with a plurality of ribs (not shown) to enhance the structural strength of the reinforcing beam 290.

It will be appreciated that the impact force is greater when the vehicle is impacted, and therefore the impact force on the ramp 230 is greater, and the ramp 230 is prevented from deforming by covering the reinforcement beam 290 with the ramp 230, thereby causing the impact force to act on the reinforcement beam 290.

In particular, in some embodiments, the reinforcement beam 290 is welded to the ramp 230 to improve the connection between the reinforcement beam 290 and the ramp 230 to prevent the reinforcement beam 290 from separating from the ramp 230 due to impact.

In some embodiments, safety shield apparatus further includes an attachment plate 700, where attachment plate 700 is disposed between sliding bracket 200 and operator's seat 300, and sliding bracket 200 and operator's seat 300 are both coupled to attachment plate 700. As such, it is provided between the sliding bracket 200 and the driver's seat 300 by the connection plate 700 to form a plane around the driver's seat 300 by means of the connection plate 700, so as to facilitate the driver's use of the driver's seat 300.

In some embodiments, the first angle is 45 ° to 55 °, and the first angle is 45 ° to 55 ° as known from basic physical knowledge, so that the impact force impacting on the inclined plane 230 generates a larger component force in the first direction X, and the sliding bracket 200 is driven by the component force to drive the driver seat 300 to slide along the sliding rail 100. In other embodiments, the first angle may be 60 °, and the specific arrangement is not limited thereto.

The first end portion 210 is slidably connected to the slide rail 100, the second end portion 220 is provided with an inclined surface 230, and the driver seat 300 is disposed above the sliding bracket 200. Thus, when the inclined plane 230 receives an impact force due to being hit, the impact force generates a component force along the first direction X, and the component force drives the sliding bracket 200 to drive the driver's seat 300 to slide along the sliding rail 100, so as to drive the driver to move away from the steering wheel located in front of the driver in the first direction X. Thereby avoided taking place the striking between steering wheel and the driver, and then protected driver's life safety, finally improved when present car receives the collision, the easy striking that takes place between steering wheel in the driver place ahead and the driver causes the problem of threat to driver's life safety.
