Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
The tailgate 100 for rear-end collision protection according to an embodiment of the present invention is described below with reference to fig. 1 to 6.
As shown in fig. 1, 2, and 3, a tailgate 100 for rear-end collision protection according to an embodiment of the first aspect of the present invention includes: the tail gate outer panel 120, the tail gate inner panel 110, and the adhesive member 130, the adhesive member 130 is located between the tail gate outer panel 120 and the tail gate inner panel 110, and the adhesive member 130 is adapted to be released and overflow out of the tail gate outer panel 120 when the tail gate outer panel 120 is impacted.
According to the tailgate 100 for rear-end collision protection of the embodiment of the present invention, the adhesive member 130 is installed between the tailgate outer panel 120 and the tailgate inner panel 110, and the adhesive member 130 may be released and may overflow to the outside of the tailgate outer panel 120 when the tailgate 100 is impacted (i.e., hit or collided), and may be adhered to an object impacting the tailgate 100. Thus, not only can a great deal of collision energy when the tail gate 100 is impacted be absorbed, but also the impacted tail gate 100 can be bonded with an object impacting the tail gate 100, and further the forward movement speed of the vehicle 1000 impacted by the tail gate 100 is reduced, so that the probability of occurrence of a chain collision accident is reduced.
It should be noted that, according to the kinetic energy theorem, when the vehicle 1000 collides, the object colliding with the vehicle 1000 at the rear side is bonded to the vehicle 1000 by releasing and overflowing the adhesive member 130, so that the vehicle 1000 collided with the tail gate 100 and the object colliding with the tail gate 100 are completely inelastically collided, thereby maximizing the collision energy loss during the collision between the two and reducing the speed of the two moving forward relative to the vehicle 1000. Therefore, the collision energy generated by the collision of the two can be absorbed to the maximum extent, and the probability of occurrence of the chain collision accident can be reduced.
In some embodiments, the tailgate 100 further comprises a release mechanism (not shown) having an opening, the release mechanism being switchable between a closed position sealing the opening and an open position opening the opening, the adhesive member 130 being capable of spilling out of the tailgate outer panel 120 through the opening when the release mechanism is in the open position.
Specifically, the side of the release device facing the adhesive member 130 is connected to the adhesive member 130, the side of the release device facing away from the adhesive member 130 is connected to the tailgate outer panel 120, and the adhesive member 130 can overflow out of the tailgate outer panel 120 through the release device via the opening in the release device. Therefore, the opening of the release device is in the closed position when the tailgate 100 is in normal use, the opening of the release device is switched to the open position when the tailgate 100 is impacted, and the adhesive member 130 overflows, and further the release device which is always in the closed position and can be switched to the open position when the tailgate 100 is impacted, so that the tailgate 100 for rear-end collision protection has higher safety in use, and the adhesive member 130 does not overflow the tailgate outer plate 120 when the tailgate 100 is not impacted.
In some embodiments, the tailgate 100 for rear-end collision protection further comprises a speed sensor and a pressure sensor connected to the tailgate outer panel 120, the speed sensor is used for detecting the relative movement speed of the rear vehicle 1000 relative to the vehicle 1000 in which the tailgate 100 is located, the pressure sensor is used for detecting the collision force applied to the tailgate outer panel 120, the speed sensor and the pressure sensor are both electrically connected to a release device, and the release device is configured to: and switching to the opening position when the speed value detected by the speed sensor is greater than a first threshold value and the impact force value detected by the pressure sensor is greater than a second threshold value.
Specifically, the speed sensor may determine a speed difference between the rear vehicle 1000 or the object moving in the rear-forward direction with respect to the speed of the vehicle 1000 in which the speed sensor is provided, and the pressure sensor may determine the magnitude of the collision force when the rear vehicle 1000 or the object moving in the rear-forward direction collides with the vehicle 1000 in which the pressure sensor is provided, so that the release device is turned on when the relative speed exceeds a first threshold value and the collision force exceeds a second threshold value, and the release device is in the closed position when either one of the relative speed and the collision force does not exceed the corresponding threshold value.
For example, the first threshold value in fig. 6 is the relative speed of the rear vehicle against the vehicle 1000 with the rear-end collision protection tailgate 100 installed, and the second threshold value is the pressure value transmitted to the pressure sensor by the rear bumper assembly 200 after the rear vehicle collides with the rear bumper assembly 200. Here, it should be understood by those skilled in the art that the relative velocity (i.e., the velocity difference between the front vehicle and the rear vehicle) and the pressure value should be calibrated according to the vehicle type, rather than fixed values, and the rear-end door 100 according to the embodiment of the present invention has a better rear-end protection effect against rear-end accidents of medium and low degree.
In this way, the relative speed of the rear vehicle 1000 is monitored in real time through the speed sensor, and the collision force is sensed by the pressure sensor, so that the viscous piece 130 overflows the tailgate outer panel 120 when needed, and the working stability of the tailgate 100 for rear-end collision protection is improved.
In some embodiments, the speed sensor and the pressure sensor are located on the edge of the tailgate outer panel 120 that is configured to abut the rear bumper assembly 200. Wherein, rear bumper assembly 200 installs the rear at tail-gate 100, and can collide with rear bumper assembly 200 earlier when rear vehicle 1000 collides with tail-gate 100 place vehicle 1000, collide with tail-gate 100 again, and then install speed sensor and pressure sensor on the border of following bumper assembly 200 and leading, not only can make pressure sensor receive the pressing of impact more direct, the measuring result is more accurate, can also make speed sensor direct observation rear vehicle's relative speed, can not receive the sheltering from of rear bumper assembly 200.
According to some embodiments of the present invention, the adhesive member 130 is a combination of one or more of silicone and viscoelastic material. Thus, the adhesive member 130 made of silica gel or viscoelastic material can not only effectively absorb the collision energy generated by the rear vehicle impact, but also buffer a part of the collision energy through the elasticity of the adhesive member 130, so that the adhesive member 130 has better buffering and energy absorbing effects.
It should be noted that the adhesive member 130 can be made of one material (e.g., silicone, viscoelastic material), and the adhesive member 130 can also be made of a combination of materials (e.g., silicone, viscoelastic material, and 304 glue)
Further, the viscoelastic material comprises a substrate, a filler and a solvent, wherein the substrate at least comprises water soluble substances, latex and epoxy resin. That is, if a viscoelastic material is used as the adhesive member 130, the substrate of the viscoelastic material is composed of at least water-soluble substance, latex, and epoxy resin. Thus, the water-soluble substance makes the viscous member 130 have physical properties of fluid, the latex makes the viscous member 130 have viscosity, and the epoxy makes chemical properties of the viscous member 130 more stable, thereby improving the operational stability of the viscous member 130 and the operational stability of the tailgate 100 for rear-end collision protection.
As shown in fig. 4, the adhesive member 130 is a coating layer between the outer sidewall of the tailgate inner panel 110 and the inner sidewall of the tailgate outer panel 120. In other words, the adhesive member 130 is disposed between the tailgate inner panel 110 and the tailgate outer panel 120, and the adhesive member 130 is uniformly filled between the tailgate inner panel 110 and the tailgate outer panel 120 to be formed as a coating. Thus, the adhesive coating makes the joining of the tailgate inner panel 110 and the tailgate outer panel 120 tighter.
According to some embodiments of the present invention, the tailgate outer panel 120 has a region of weakness adapted to rupture upon release of the adhesive member 130 to allow the adhesive member 130 to spill out of the tailgate outer panel 120 through the region of weakness. Specifically, a plurality of weak areas are provided on the tailgate outer panel 120, and thus, when a rear-end collision of the vehicle 1000 occurs, the weak areas of the tailgate outer panel 120 are broken first, and a release device provided behind the weak areas is switched to an open position and overflows the adhesive member 130. From this, through set up weak area on tail-gate planking 120, when making vehicle 1000 take place the rear-end accident, viscidity piece 130 can be preferentially followed the weak area and spilled over, and then guarantees that after the collision reaches viscidity piece 130 and spills over the condition, viscidity piece 130 can spill over outside tail-gate planking 120, has improved the job stabilization nature of tail-gate 100 for the protection of knocking into the back.
Further, when the adhesive member 130 overflows, the collision energy can be uniformly transmitted to the tailgate inner panel 110 and other surrounding components, so that the permanent damage of the components of the vehicle 1000 can be reduced, and the service life of the vehicle 1000 can be prolonged.
As shown in fig. 5, the tailgate outer panel 120 has an inwardly depressed license plate installation region, and the adhesive member 130 is disposed on a region of the tailgate outer panel 120, excluding the license plate installation region, between the tailgate outer panel 120 and the tailgate inner panel 110. Therefore, when the vehicle 1000 is collided by the adhesive members 130 uniformly distributed between the tailgate inner panel 110 and the tailgate outer panel 120, the force applied to the tailgate outer panel 120 and the tailgate inner panel 110 is more uniform, the collision force is more sufficiently absorbed, and the installation of photographing on the vehicle 1000 is facilitated.
The tailgate 100 for rear-end collision protection according to the embodiment of the present invention is particularly suitable for passenger cars, light trucks, and vans.
The vehicle 1000 according to the embodiment of the second aspect of the invention includes the tailgate 100 for rear-end collision protection as in the above-described embodiment.
According to the vehicle 1000 of the embodiment of the invention, by arranging the rear-end collision protection tailgate 100, the collision energy can be absorbed to the maximum when the vehicle 1000 collides with the rear vehicle 1000, and the rear vehicle 1000 can be bonded to the vehicle 1000 to which the rear-end collision protection tailgate 100 is mounted, so that the probability that the vehicle 1000 to which the rear-end collision protection tailgate 100 is mounted continues to move forward and a rear-end collision accident occurs is reduced, and the driving safety of the vehicle 1000 is improved.
The operation of the tailgate 100 for rear-end collision protection according to the embodiment of the present invention will be described in detail with reference to fig. 6.
As shown in fig. 6, in the vehicle 1000 with the rear-end collision protection tailgate 100 installed, during driving, the speed sensor detects the speed of the rear vehicle, if the relative speed of the rear vehicle exceeds a first threshold and after a rear-end collision occurs, the pressure sensor detects that the pressure applied to the tailgate outer panel 120 exceeds a second threshold, the release device is switched to the open position, the adhesive member 130 overflows, and when the pressure sensor detects that the pressure applied to the tailgate outer panel 120 does not exceed the second threshold, the release device is still in the closed position, and the adhesive member 130 does not overflow.
