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.
A passenger vehicle apparatus 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 4.
Unless otherwise specified, the front-rear direction in the present application is the longitudinal direction of the vehicle, i.e., the X direction; the left and right directions are the transverse direction of the vehicle, namely the Y direction; the up-down direction is the vertical direction of the vehicle, i.e., the Z direction.
As shown in fig. 1, a passenger vehicle apparatus 100 of the present invention includes: a trunk door 10, an actuator 14 and a sail 20.
The trunk door 10 is pivotally mounted on a lateral side of the body 200 of the passenger car 1000 about a first pivot axis, and the trunk door 10 is selectively fastened to the body 200 by an opening and closing latch 11, wherein the first pivot axis is along a longitudinal direction of the passenger car 1000.
As shown in fig. 1, the upper end of the trunk door 10 is hinged to the side of the body 200 of the passenger car 1000, the lower end of the trunk door 10 is selectively fastened to the body 200 through the opening/closing latch 11, and the actuator 14 is connected to the opening/closing latch 11 to selectively drive the opening/closing latch 11 to open.
When the lower end of the trunk door 10 is buckled to the vehicle body 200 through the opening and closing clamp 11, the trunk door 10 is closed; as shown in fig. 1, when the opening and closing card 11 is opened, the trunk door 10 is opened.
In some embodiments, the trunk door 10 is pivotably installed at the side of the body 200 of the passenger car 1000 by an elastic hinge 12, and drives the trunk door 10 to be unfolded when the opening and closing card 11 is opened. That is, when the opening and closing clip 11 is opened, the elastic hinge 12 drives the trunk door 10 to be automatically opened even if a driving force is applied or a certain resistance to water flow is encountered.
In some embodiments, as shown in fig. 1, the trunk door 10 makes an angle of not more than 90 ° with the side of the vehicle body 200 at the maximum opening angle.
It can be understood that when the included angle between the trunk door 10 and the side of the vehicle body 200 at the maximum opening angle is greater than 90 °, the water flow below the trunk door 10 goes upward, and by arranging the trunk door 10 with a small angle, the resistance between the trunk door 10 and the water can be increased to the maximum extent, and the sinking time of the vehicle body 200 can be delayed.
In a practical implementation, as shown in fig. 2, the lower end of the trunk door 10 may be connected to the vehicle body 200 by a plurality of (e.g., two) elastic hinges 12, the upper end of the trunk door 10 is provided with an opening/closing card 11, and the trunk door 10 may be of a conventional sheet metal structure.
The actuator 14 is configured to drive the opening/closing card 11 to open when the trunk door 10 needs to be opened.
In some embodiments, the actuator 14 may include a gas generator that reacts quickly and is not affected by water, although the actuator 14 may be other mechanical type structures.
As shown in fig. 1, both left and right sides of the passenger car 1000 may be provided with the luggage hatch 10 of the above-described structure.
As shown in fig. 1 and 3, the sail 20 is mounted to the vehicle body 200, and the sail 20 has a stowed state and a deployed state, and in the deployed state, a normal line of the sail 20 is along a longitudinal direction of the passenger vehicle 1000.
As shown in fig. 1, both the left and right sides of the passenger vehicle 1000 may be provided with sails 20 of the above-described configuration.
It can be understood that, when the passenger car 1000 falls into water, the actuator 14 drives the switch card 11 to open, the trunk door 10 opens automatically, and forms a large resistance vortex with the water flow, which can increase the sinking resistance of the passenger car 1000, and if the most serious accident that the car head falls into water occurs, the normal of the sail 20 in the unfolded state is along the longitudinal direction of the passenger car 1000, so that the falling time of the passenger car 1000 can also be prolonged after the sail 20 is unfolded.
The passenger car device 100 according to the embodiment of the invention has a simple structure, the improvement on the passenger car 1000 is small, the production cost of the passenger car 1000 can be saved, the simplicity of the structural design can be kept, and the falling time can be prolonged for the passenger car 1000 entering water in various postures.
In some embodiments, as shown in fig. 1 and 2, the side of the luggage compartment door 10 is mounted with a spoiler structure 13 protruding from the side of the luggage compartment door 10.
It will be appreciated that the trunk door 10 is generally a smooth flat plate, and the spoiler 13 may adjust the flow pattern on the trunk door 10 to increase the resistance to vortex generation.
In a practical implementation, the spoiler structure 13 may comprise a gas-filled bag mounted on a first side of the luggage compartment door 10, the first side facing downwards when the luggage compartment door 10 is open. The airbag can increase the buoyancy of the passenger car 1000 to a certain extent, and has a small influence on the weight of the passenger car 1000.
When the upper end of the trunk door 10 is hinged to the vehicle body 200, the first lateral side is the inner lateral side of the trunk door 10, the airbag can be adhered to the inner lateral side of the trunk door 10, and when the trunk door 10 is unfolded, the inner lateral side faces downward to the water flow. Because the turbulent flow structure 13 is designed as an inflatable bag, the simple and convenient installation mode of a sticking type can be adopted.
As shown in fig. 1 and 2, the plurality of air bags are arranged at intervals. The inflatable bags are long and extend along the longitudinal direction of the passenger car 1000, and when the luggage compartment door 10 is unfolded, the inflatable bags are arranged at intervals along the transverse direction of the passenger car 1000.
Of course, the airbag may be disposed in other directions, such as extending in the transverse direction of the passenger vehicle 1000, and a plurality of airbags are arranged at intervals in the longitudinal direction of the passenger vehicle 1000 when the luggage hatch 10 is deployed.
As shown in fig. 3, the sail 20 comprises: a support frame and a canvas 21.
The support frame has a storage position and a deployment position, the support frame is always kept at the storage position through the locking mechanism 23, and when the locking mechanism 23 is unlocked, the support frame is switched to the deployment position. The canvas 21 is mounted to the support frame, and the canvas 21 is deployed when the support frame is switched to the deployed position. In this way, the sail 20 does not interfere with the storage space of the luggage compartment during normal use.
In a practical implementation, the support frame may comprise at least two support rods 22, the support rods 22 are telescopic, and the support rods 22 comprise multiple sections connected elastically, two sections at two ends of the support rods 22 are locked by the locking mechanism 23 to keep the support rods 22 in a contracted state, and the canvas 21 is connected between the two support rods 22.
The multi-section support rod 22 is embedded with a spring, and the locking mechanism 23 may include a latch, so that when the passenger car 1000 falls into the water and the luggage compartment door 10 is opened, the latch of the sail 20 is pulled out, and the support rod 22 automatically extends. The maximum unfolding length of the canvas 21 is longer than that of the supporting rod 22, so that a reserved area is reserved, and the tensioning tension is reduced. The canvas 21 protruding out of the vehicle body 200 increases the lateral resistance coefficient of the vehicle body 200, and prolongs the submergence time of the vehicle body 200 in water.
As shown in fig. 4, the passenger vehicle apparatus 100 may further include an acquisition unit 30 and a controller 40.
Wherein the obtaining unit 30 is configured to obtain the state information of the vehicle body 200, in some embodiments, the obtaining unit 30 includes a GPS31, a gyroscope (tilt sensor) 32, and a water pressure sensor 33.
The controller 40 is communicatively connected to the acquisition unit 30 and the actuator 14, and the controller 40 is configured to activate the actuator 14 when the passenger vehicle 1000 falls into water. The controller 40 is also configured to control the door to open when the posture of the vehicle body 200 reaches the target posture.
The controller 40 will determine whether the vehicle body 200 is submerged by combining the GPS31 location and the water pressure sensor 33 on the vehicle body 200. If yes, the controller 40 sends a signal to the actuators 14 of the trunk doors 10 on both sides of the vehicle body 200 to open the trunk doors 10, and after the trunk doors 10 are opened, controls the locking mechanism 23 to be opened, and the sail 20 is unfolded. The controller 40 judges the current movement condition of the vehicle body 200 by reading data of the gyroscope 32 or the tilt angle sensor, and if the posture change of the vehicle body 200 is relatively mild, the controller 40 sends an opening signal to the vehicle door ECU50 to open the front and rear vehicle doors, so that the self-rescue channel is ensured to be smooth.
As shown in fig. 5, the present application also discloses a passenger vehicle 1000.
A passenger vehicle 1000 of an embodiment of the present invention includes any of the passenger vehicle apparatus 100 of the embodiments described above.
