Description

Technical Field

[0001] The present invention relates to the technical field of automobiles, and particularly to a side-opening electric vehicle door for commercial vehicles. Background Art

[0002] With the improvement of the intelligent level of the automobile door system, electric vehicle doors are configured on some high-end models, but they are less applied in the domestic commercial vehicle field.

[0003] The existing side-opening doors of commercial vehicles generally adopt manual opening and closing methods. Most electric vehicle doors are rear-swing doors, which are not good in terms of door intelligence and cannot provide customers with personalized and technological configuration options. They are generally applied to buses and some special vehicles. There are certain differences between the existing side-opening electric vehicle doors and commercial vehicles in terms of door opening and closing control forms, door layout structures, and door performance parameters. Therefore, there is an urgent need to propose a side-opening electric vehicle door for commercial vehicles. Summary of the Invention

[0004] The purpose of the present invention is to provide a side-opening electric vehicle door for commercial vehicles in view of the deficiencies of the prior art.

[0005] The present invention is implemented by adopting the following technical solutions:

[0006] A side-opening electric vehicle door for commercial vehicles includes:

[0007] A door lock system, including a lock body and a lock body actuator. The lock body actuator controls the lock body to execute the door opening and closing commands, realizes the functions of semi-lock, full-lock, and self-opening / self-suction reset, and feeds back the semi-lock, full-lock, and self-opening / self-suction reset signals to the door controller;

[0008] An electric limiter. The electric limiter feeds back the real-time position of the door to the door controller by means of Hall signal transmission, and controls the speed at different stages during the door opening and closing process. When the moving resistance of the electric limiter is greater than a preset value before the door is closed to the semi-lock state, it is fed back to the door controller. The door controller then transmits the information to stop the door closing to the door lock system and reverses the limiting motor of the electric limiter to enable the door to achieve the anti-pinch function;

[0009] A radar, which detects obstacles in a predetermined area, that is, the movement envelope during the door opening and closing process. When the radar detects an obstacle during the door opening and closing process, it feeds back the distance between the door and the obstacle to the door controller in real time through the radar controller. The door controller stops the movement after the door moves to a set safe distance according to the real-time distance between the door and the obstacle, enabling the door to achieve the obstacle recognition function;

[0010] A camera monitors objects that quickly move towards the front and rear of the vehicle and approach the door during the opening and closing process. When receiving an electric door opening command and determining that there are objects approaching the door in the front and rear of the vehicle, the vehicle will give an alarm prompt and feedback the non-execution of the electric door opening command to the door controller, enabling the door to achieve an anti-collision function;

[0011] A door controller determines the state of the door by collecting the status signals of the door lock system and the electric limiter, and combines the door state and the requirements of the door opening and closing execution command to complete the opening and closing function of the door.

[0012] Further, the lock body, the lock body actuator, and the electric limiter are all provided on the inner door panel; the lock body is connected to the lock body actuator by a wire; a hidden external handle is provided on the outer door panel, and the hidden external handle is connected to the lock body by a wire to achieve manual door opening;

[0013] The lead screw of the electric limiter is connected to the side wall through a lead screw bracket, and the electric limiter is connected to the inner door panel through a main body bracket;

[0014] The door controller and the radar controller are provided on the door lifter mounting plate;

[0015] The radar is provided on the outer door panel; the camera is provided on the vehicle's electronic rearview mirror.

[0016] Further, the lock body actuator is provided with a lock body motor. The lock body realizes the functions of semi-locking, full-locking, and self-opening / self-suction reset through the lock body motor, and feeds back the signals of semi-locking, full-locking, and self-opening / self-suction reset to the door controller through the lock body actuator.

[0017] Further, if the reaction force of the door seal is too small, the lock body cannot complete the self-opening function; if the reaction force of the door seal is too large, the door will open too wide after self-opening or the lock body cannot complete the self-suction function. Therefore, to achieve the self-opening / self-suction reset function, it is necessary to match and calibrate the force of the lock body during self-opening / self-suction reset with the return force of the door seal, so that the door bounces open to a predetermined position after the lock body executes the self-opening command.

[0018] Further, the electric limiter is internally provided with a limit motor gear set and a self-speed control module. The output shaft of the limit motor is connected to the limit motor gear set to drive the lead screw to move. The self-speed control module realizes the control of the speed at different stages during the opening and closing process of the door through calibration, and feeds back the real-time position of the door to the door controller.

[0019] Further, the control methods for opening the vehicle door include a mobile phone, a central control key, a hidden exterior handle, control buttons provided on the door trim and the seat armrest, and an in-vehicle multimedia control screen; the control methods for closing the vehicle door include a mobile phone, a central control key, a hidden exterior handle, control buttons provided on the door trim and the seat armrest, an in-vehicle multimedia control screen, and a brake pedal.

[0020] Further, the process for opening the vehicle door is as follows: when the vehicle door is in the fully locked state and the door lock system receives an opening signal, the semi-lock signal and the full-lock signal of the lock body are in the valid state. After the door controller determines that the tooth plate signal of the lock body is valid, it drives the lock body to execute the self-opening command. At this time, the semi-lock signal and the full-lock signal of the lock body are in the invalid state; after the door controller receives that the full-lock signal of the lock body is in the invalid state, it sends an opening command to the electric limiter. The electric limiter drives the vehicle door to execute the opening command through the lead screw. During the opening process, the door controller judges the opening angle of the vehicle door by receiving the Hall signal of the electric limiter, and stops moving when the vehicle door is opened to the set angle; after the lock body executes the self-opening command, the self-opening reset signal is valid at this time, and the lock body needs to execute the self-opening reset. When the self-opening reset signal of the lock body is invalid, the door controller judges that the self-opening reset of the lock body is completed. At this time, the opening of the vehicle door is completed.

[0021] Further, the process for closing the vehicle door is as follows: when the vehicle door is in the open state and the door lock system receives a closing signal, the semi-lock signal and the full-lock signal of the lock body are in the invalid state. After the door controller determines that the tooth plate signal of the lock body is invalid, it drives the electric limiter to move. When the electric limiter drives the vehicle door to rotate to the semi-lock state of the lock body, the semi-lock signal of the lock body is valid and the full-lock signal is invalid. When the door controller receives that the semi-lock signal of the lock body is valid, the electric limiter stops operating. The door controller drives the lock body actuator to drive the lock body to perform self-suction of the door lock through the wire. After the self-suction of the door lock is completed, the semi-lock signal and the full-lock signal of the lock body are valid. After the door controller determines that the tooth plate signal of the lock body is valid, it drives the lock body actuator to perform self-suction reset. When the door controller receives that the self-suction reset signal of the lock body actuator is in place, it stops driving. At this time, the closing of the vehicle door is completed.

[0022] Compared with the prior art, the present invention has the following beneficial technical effects:

[0023] The door controller judges the state of the vehicle door by collecting various state signals of the door lock system and the electric limiter, and combines the door state and the requirements of the door opening and closing execution commands to realize the opening and closing functions of the vehicle door; by arranging a radar and a camera to identify obstacles in the preset area, and by calibrating the anti-pinch resistance value of the electric limiter, the safety during the electric opening and closing of the door is ensured.

[0030] In order to enable those skilled in the art of the present technology to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0031] As Figures 1-4 shown, a side-opening electric vehicle door for commercial vehicles includes:

[0032] A door lock system, including a lock body 1 and a lock body actuator 2. The lock body actuator 2 controls the lock body 1 to execute the door opening and closing commands, realizes the functions of half-lock, full-lock, and self-opening / self-suction reset, and feeds back the half-lock, full-lock, and self-opening / self-suction reset signals to the door controller 4;

[0033] An electric limiter 3. The electric limiter 3 feeds back the real-time door position to the door controller 4 in a manner of Hall signal transmission, and controls the speeds at different stages during the door opening and closing processes; when the moving resistance of the electric limiter 3 is greater than a preset value before the door closes to the half-lock state, it is fed back to the door controller 4, and the door controller 4 then transmits the information to stop the door closing to the door lock system and reverses the limit motor of the electric limiter 3 to enable the door to realize the anti-pinch function;

[0034] A radar 7 for detecting obstacles in a predetermined area, that is, the movement envelope during the door opening and closing processes. When the radar 7 detects an obstacle during the door opening and closing processes, the distance between the door and the obstacle is fed back to the door controller 4 in real time through the radar controller 5. The door controller 4 stops the movement after the door moves to a set safe distance according to the real-time distance between the door and the obstacle, enabling the door to realize the obstacle recognition function;

[0035] A camera monitors objects that quickly move towards the front and rear of the vehicle and approach the door during the opening and closing process. When receiving an electric door opening command and determining that there are objects approaching the door in front of and behind the vehicle, the vehicle will give an alarm prompt and feedback the non-execution of the electric door opening command to the door controller 4, enabling the door to achieve an anti-collision function.

[0036] The door controller 4 collects the status signals of the door lock system and the electric limiter 3, determines the state of the door, and combines the door state and the requirements of the door opening and closing execution command to complete the opening and closing function of the door.

[0037] The lock body 1, the lock body actuator 2, and the electric limiter 3 are all arranged on the inner panel of the door; the lock body 1 is connected to the lock body actuator 2 through a wire rope 6; the hidden external handle 8 is arranged on the outer panel of the door, and the hidden external handle 8 is connected to the lock body 1 through a wire rope 6 to achieve manual door opening.

[0038] The lead screw 31 of the electric limiter 3 is connected to the side wall through a lead screw bracket 32, and the electric limiter 3 is connected to the inner panel of the door through a main body bracket 33.

[0039] The door controller 4 and the radar controller 5 are arranged on the door lifter mounting plate.

[0040] The radar 7 is arranged on the outer panel of the door; the camera is arranged on the vehicle electronic rearview mirror.

[0041] The lock body actuator 2 is provided with a lock body motor. The lock body 1 realizes the functions of semi-lock, full-lock, and self-opening / self-sucking reset through the lock body motor, and feeds back the signals of realizing semi-lock, full-lock, and self-opening / self-sucking reset to the door controller 4 through the lock body actuator.

[0042] Since too small a reaction force of the door seal strip will cause the lock body 1 to be unable to complete the self-opening function, and too large a reaction force of the door seal strip will cause the door to open too wide after self-opening or the lock body 1 to be unable to complete the self-sucking function, therefore, to realize the self-opening / self-sucking reset function, it is necessary to match and calibrate the force of the lock body 1 during self-opening / self-sucking reset with the return force of the door seal strip, so that the door bounces open to a predetermined position after the lock body 1 executes the self-opening command.

[0043] The electric limiter 3 is internally provided with a limit motor gear set and a self-speed control module. The output shaft of the limit motor is connected to the limit motor gear set to drive the lead screw 31 to move. The self-speed control module calibrates to control the speed at different stages during the opening and closing process of the door and feeds back the real-time door position to the door controller 4.

[0044] The control methods for opening the vehicle door include a mobile phone, a central control key, a hidden exterior handle 8, control buttons provided on the door trim and the seat armrest, and an in-vehicle multimedia control screen; the control methods for closing the vehicle door include a mobile phone, a central control key, a hidden exterior handle 8, control buttons provided on the door trim and the seat armrest, an in-vehicle multimedia control screen, and a brake pedal.

[0045] The process for opening the vehicle door is as follows: When the vehicle door is in the fully locked state and the door lock system receives an opening signal, the half-lock signal and the full-lock signal of the lock body 1 are in the valid state. After the door controller 4 determines that the tooth plate signal of the lock body 1 is valid, it drives the lock body 1 to execute the self-opening command. At this time, the half-lock signal and the full-lock signal of the lock body 1 are in the invalid state; after the door controller 4 receives that the full-lock signal of the lock body 1 is in the invalid state, it sends an opening command to the electric limiter 3. The electric limiter 3 drives the vehicle door to execute the opening command through the lead screw 31. During the opening process, the door controller 4 judges the opening angle of the vehicle door by receiving the Hall signal of the electric limiter 3 and stops moving when the vehicle door is opened to the set angle; after the lock body 1 executes the self-opening command, the self-opening reset signal is valid at this time, and the lock body 1 needs to execute the self-opening reset. When the self-opening reset signal of the lock body 1 is invalid, the door controller 4 judges that the self-opening reset of the lock body 1 is completed. At this time, the execution of opening the vehicle door is completed.

[0046] The process for closing the vehicle door is as follows: When the vehicle door is in the open state and the door lock system receives a closing signal, the half-lock signal and the full-lock signal of the lock body 1 are in the invalid state. After the door controller 4 determines that the tooth plate signal of the lock body 1 is invalid, it drives the electric limiter 3 to move. When the electric limiter 3 drives the vehicle door to rotate until the lock body 1 reaches the half-lock state, the half-lock signal of the lock body 1 is valid and the full-lock signal is invalid. When the door controller 4 receives that the half-lock signal of the lock body 1 is valid, the electric limiter 3 stops operating. The door controller 4 drives the lock body actuator 2 to drive the lock body 1 to perform self-suction of the door lock through the wire rope 6. After the self-suction of the door lock is completed, the half-lock signal and the full-lock signal of the lock body 1 are valid. After the door controller 4 determines that the tooth plate signal of the lock body 1 is valid, it drives the lock body actuator 2 to perform self-suction reset. After the door controller 4 receives that the self-suction reset signal of the lock body actuator 2 is in place, it stops driving. At this time, the execution of closing the vehicle door is completed.

Without departing from the spirit and essence of the present invention, those of ordinary skill in the art can make various equivalent modifications or substitutions to the embodiments of the present invention, and these modifications or substitutions should all be within the scope of the present invention. / Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered by the protection scope of the present invention.
