AUTOMATIC VEHICLE DOOR OPENING AND CLOSING SYSTEM

Abstract

An automatic vehicle door opening and closing system is a system for a vehicle having a controller with at least one button for each door having the system installed, that allows the driver of the vehicle to open or close a preferred door on the vehicle without leaving the driver's seat. A lockout circuit prevents the doors from opening with the automatic function while the vehicle is in motion though the doors may be opened manually if not locked using the vehicle's own door lock system.

DETAILED DESCRIPTION

[0030] As discussed above, embodiments of the present invention relate to an automatic door closer and more particularly to an automatic vehicle door opening and closing system as used to improve the safety and convenience in opening and closing car doors without leaving the driver seat.

[0031] Generally speaking, a automatic vehicle door opening and closing system is a system for a vehicle having a controller with at least one button for each door having the system installed, that allows the driver of the vehicle to open or close a preferred door on the vehicle without leaving the driver's seat. A lockout circuit prevents the doors from opening with the automatic function while the vehicle is in motion though the doors may be opened manually if not locked using the vehicle's own door lock system.

[0032] In greater detail now, referring to the drawings by numerals of reference there is shown in FIG. 1, a perspective view illustrating a first embodiment of automatic vehicle door opening and closing system 100 according to an embodiment of the present invention.

[0033] Automatic vehicle door opening and closing system 100 enables a user to be able to remain seated in the driver seat of vehicle 102 and to either open or to close any vehicle door 214 on vehicle 102 with the use of closing arm 105, which is actually an opening and closing arm 105 attached between vehicle door jamb 165 of vehicle 102 and hinge side 166 of vehicle door 103, controlled by door controller 120 located within arm's reach of vehicle 102 driver seat. Automatic vehicle door opening and closing system 100 preferably comprises at least one closing arm 105 having door attachment end 106 adapted to be pivotally attached to hinge side 166 of vehicle door 103, and vehicle attachment end 107 adapted to be pivotally attached to vehicle door jamb 165 of vehicle 102. Closing arm 105 is adapted to pivotally swing vehicle door 103 to a user preferred position upon an existing vehicle door hinge axis.

[0034] Door controller 120 is adapted to be connected to vehicle 102 dash board that includes a plurality of pushbuttons 121, each in communication with door controller 120 and adapted to allow the user to manually control the pivotal swinging motion of vehicle door 103 via pressing of one of the plurality of pushbuttons 121 that are adapted to be in communication with door controller 120. Door handle 104 preferably has door handle activation switch 155 adapted to be activated by door handle 104 and signal door controller 120 to thereby cause vehicle door 103 to open via closing arm 105 when door handle 104 is released.

[0035] Referring now to FIG. 2, is a perspective view illustrating the first embodiment of automatic vehicle door opening and closing system 100 according to an embodiment of the present invention of FIG. 1.

[0036] At least one electric motor 110 is in operative communication with closing arm 105 and is adapted to actuate closing arm 105 to pivotally swing vehicle door 103 to the user preferred position, most generally, to the open or the closed position. Closing arm 105 may be operated by electric motor 110, in electric embodiments, where closing arm 105 is formed as toothed rack 135 movable by pinion gear 140 that is operated by electric motor 110 via door controller 120. Door controller 120 is a direct current powered electric motor 110. Closing arm 105 is preferably covered with flexible boot 170 that is designed to expand and contract as vehicle door(s) 103 is opened and closed to prevent contact with toothed rack 135 which is able to be seen and contacted between vehicle door(s) 103 and vehicle door jamb 165 by pulling flexible boot 170 back. Closing arm 105 may have a slight arcuate shape to prevent binding during the opening motion trajectory of the hinged vehicle door 103. The ends of closing arm may instead be attached at door attachment end and at vehicle attachment end with a hinged pivotal joint to facilitate the motion. Electric motor 110 is located between the inner and the outer shell of the vehicle body behind vehicle door jamb 165 and so is not seen or able to be contacted unintentionally, but may be accessed through an access opening from within the cab near the floor forward of vehicle door jamb 165.

[0037] Power source 125 for automatic vehicle door opening and closing system 100 to operate electric motor(s) 110 and obstruction sensor switch(es) 115, is power source 125 or battery 126 of vehicle 102 for starting vehicle 102 and for operating the accessories of vehicle 102. Automatic vehicle door opening and closing system 100 is useful for increasing safety and convenience of the user by enabling the user to choose between either closing vehicle door 103 or opening vehicle door 103 without having to leave the driver seat of vehicle 102.

[0038] Referring now to FIG. 3, is a perspective view illustrating a second embodiment of automatic vehicle door opening and closing system 100 according to an embodiment of the present invention of FIG. 1.

[0039] System 100 may be a hydraulically operated system 100 and may further have hydraulic pump 130 connected to and operated by electric motor(s) 110. Closing arm 105 may be formed as hydraulic cylinder 131, in hydraulic embodiments, and adapted to be in communication with hydraulic pump 130 such that closing arm 105 is adapted to be extendable and contractible in length via hydraulic pump 130.

[0040] Referring now to FIG. 4A, is a perspective view illustrating the second embodiment automatic vehicle door opening and closing system 100 according to an embodiment of the present invention of FIG. 1.

[0041] Door controller 120 may have a manual override operation by pressing one of pushbuttons 121 on door controller 120. Each respective one of pushbuttons 121 is adapted to correspond to a different vehicle door 103 that has automatic vehicle door opening and closing system 100. An automatic operation may include a duration programmable time delay 145 closure function that operates from a time clock based function that may be in the form of a program within door controller 120. Closing arm 105 may include spring member 150 for assisting vehicle door 103 closing function. Spring member 150 may be either a compression spring member 150 or a tension spring member 150 depending on which embodiment it is used in, for instance toothed rack 135 and pinion gear 140 embodiment may utilize a tension spring member 150 while hydraulic pump 130 embodiment may utilize a compression spring member 150.

[0042] Referring now to FIG. 4B is a diagram illustrating vehicle in motion lockout circuit 160 of automatic vehicle door opening and closing system 100 according to an embodiment of the present invention of FIG. 1.

[0043] Safety features preferably include vehicle in motion lockout circuit 160 that is in communication with the central processing unit of vehicle 102 and is adapted to prevent vehicle door(s) 103 from automatically opening while vehicle 102 is in motion. Vehicle door(s) 103 may still be opened manually provided that vehicle 102 existing door-lock system is not engaged. At least one obstruction sensor switch 115 is adapted to be connected to vehicle door jamb 165 to detect an object such as a person's leg or arm that is located within the plane of vehicle door closed area 190 while vehicle door(s) 103 is in the door open position, and to stop and reverse the closing motion of vehicle door(s) 103 to thereby move vehicle door(s) 103 to the door open position. Obstruction sensor switch 115 may be formed as pressure detecting switch 116 adapted to detect resistance when closing vehicle door(s) 103 and to reverse the closing motion of vehicle door(s) 103 to the open position to prevent injury, but obstruction sensor switch 115 may also be formed as motion detector 117 adapted to detect motion within vehicle door closed area 190 when vehicle door(s) 103 is/are closing, and reverse the motion of vehicle door(s) 103 to an open position. Both types of sensors 115 may also be employed.
