FIG. 1 is a schematic illustration of a crashworthy vehicle door 10 in accordance with one embodiment of the present utility model; FIG. 2 is a schematic block diagram of the components of the anti-collision vehicle door 10 according to one embodiment of the utility model; fig. 3 is a schematic diagram illustrating the operation of the line laser detection module 20 in the anti-collision vehicle door 10 according to one embodiment of the present utility model. The crashworthy door 10 may generally include: the vehicle door body 11, one or more line laser detection modules 20, a vehicle door actuator 40 and a main control board 30.
The door body 11 is used as a main body member of the door 10, and in some embodiments, can be automatically opened and closed by the door actuator 40, so that the operation of a driver is reduced, and the use experience is improved.
The line laser detection module 20 is disposed on the door body 11, and may be disposed on the outside of the door body 11. Due to the small size of the line laser detection module 20, it can be as small as 1cm or even smaller, which has little influence on the appearance and structure of the door body 11 itself.
Each line laser detection module 20 may include: a line laser emitter 21, a laser detector 22, and a beam expanding lens 23. The line laser transmitter 21 may employ a VCSEL light source. VCSELs are known as vertical cavity Surface emitting lasers (VERTICAL CAVITY surfaces EMITTING LASER) based on gallium arsenide semiconductor materials. Compared with the existing laser light source, the laser light source has the advantages of small volume, round output light spots, single longitudinal mode output, small threshold current and low price. The line laser detection module 20 of the present embodiment is particularly suitable for use, and can reliably output laser light. The line laser emitter 21 is located outside the door body 11, and interference of the metallic paint surface can be avoided. The line laser detection module 20 is a semiconductor process, does not require additional thin film material conduction, and has long-term working stability far higher than that of an ultrasonic radar.
In some embodiments, the detection laser is an infrared laser, thereby avoiding visual interference with the visual laser.
The line laser emitter 21 is for emitting an elongated detection laser to the outside of the door body 11. The laser detector 22 is for detecting reflected light of the detection laser by an object outside the door body to determine the distance from the door body 11 to the external object from the reflected light.
The beam expander lens 23 of the line laser detection module 20 is disposed in the emission direction of the line laser emitter 21, and is configured to expand the detection laser beam and expand the detection area. The laser detection module 20 enlarges the detection area by using the beam expanding lens 23, and the long detection laser can simultaneously realize the omnibearing detection of the obstacle in one direction of the vehicle door.
The line laser detection module 20 can be arranged at the lower plastic plate 111 of the vehicle door body 11, the decorative strip 112 in the middle and the vehicle door handle 113 according to measurement requirements, is flexible in arrangement, and meets various detection requirements. The line laser detection module 20 provided at the lower plastic panel 111 may detect the lower portion of the door 10, for example, an obstacle at a set height above the ground to detect a ground obstacle such as a road edge. In some embodiments, the line laser detection module 20 avoids direct detection of the ground and avoids interference from ground reflections.
The line laser detecting module 20 provided at the molding 112 in the middle of the door body 11 can detect a wall surface protrusion or the like.
The line laser detecting module 20 provided at the door handle 113 of the door body 11 is located substantially in the middle in the height direction of the door 10, and may be provided as a longitudinal line laser detecting module for outputting laser light in the height direction.
In some embodiments, the line laser detection modules 20 may be arranged in multiple groups, for example, at the lower plastic plate 111 of the door body 11, at the trim strip 112 in the middle, and at the door handle 113, so as to realize detection of full access.
Fig. 4 is a schematic view of the detection range of the line laser detection module 20 in the crashworthy door 10 shown in fig. 1. The line laser detection module 20 may be plural, and may include a transverse line laser detection module and a longitudinal line laser detection module. The transverse line laser detection module may be used to emit detection laser light extending transversely along the crashproof door 10, i.e. to detect the front-rear direction of the vehicle from front to rear at a certain height. The longitudinal line laser detection module can be used for emitting detection laser extending along the height direction of the anti-collision vehicle door 10, namely, detection is carried out from top to bottom at a certain front and rear position of the vehicle.
The door actuator 40 is connected to the line laser detection module signal 20 and configured to control the movement state of the door body 11 and/or output a warning signal according to the distance. For example, the door actuator 40 determines that the obstacle is located in the movement range of the door 10 in the main control board 30, and can controllably stop the door 10 to continue opening and closing. In addition, the door actuator 40 may give a warning to the driver by means of sound and light or the like. In some embodiments, the door actuator 40 may issue a reminder through an on-board system on the vehicle.
The main control board 30 is provided with: a power interface 31, a communication interface 32, a laser driver 33, a microprocessor 34. Among the above components, the power interface 31 is used to connect an in-vehicle power supply to access an operating power supply, for example, the power interface 31 may access a 12V power supply of the vehicle.
The communication interface 32 is used to connect the vehicle control device for information interaction with the vehicle control device, and the communication interface 32 may be used to implement information/data transmission between the vehicle control device and the microprocessor 34 in various wired or wireless manners.
The laser driver 33 is connected to the line laser detection module 20 and configured to drive the line laser detection module 20.
The microprocessor 34 is connected to the communication interface 32, the laser driver 33, the line laser detection module 20, and the door actuator 40, respectively, and is configured to process data and information on the main control board 30. Microprocessor 34 may be a single core processor, a multi-core processor, an embedded process that implements information/data interaction through I/O and processes the information/data by its own computing power, sending instructions such as control signals.
The working principle of the line laser detection module 20 may be: after passing through the beam expander lens 23, the line laser beam generated by the line laser emitter 21 is angle-expanded as necessary in the lateral and longitudinal directions of the vehicle, thereby expanding the detection range. After the laser light encounters an obstacle, the reflected light passes through a beam expander lens 23 and is received by a laser detector 22. The received signal is transmitted back to the Microprocessor (MCU) 34 of the main control board 30. The microprocessor 34 calculates the time for the laser to emit to the return signal, thereby obtaining the distance of the obstacle, and according to the distance, the movement control command is transmitted to the vehicle through the communication interface 31, the action of the door 10 is executed by the door actuator 40, and the reminding signal is output according to the need.
Fig. 5 is a schematic view of a vehicle 1 according to an embodiment of the utility model. The utility model also provides a vehicle 1 comprising a crashproof door 10 in either embodiment. The anti-collision door 10 may be any cockpit door or back door of the vehicle 1.
The crashproof door 10 of the present embodiment detects the distance of the door outside obstacle using the line laser detection module 20. The line laser detection module 20 is small in size and is convenient to mount on the door body 11. In addition, the long-term working stability of the laser detection module 20 is good, the measurement is accurate, the detection error is small, and the car door can be reliably prevented from being scratched or collided.
By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been shown and described herein in detail, many other variations or modifications of the utility model consistent with the principles of the utility model may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the utility model.
