Detailed Description
The following is further detailed by way of specific embodiments:
a hidden external-open handle limiting structure mainly comprises an actuating mechanism, a signal feedback mechanism, a controller, a push rod 2 and an external-open handle 4, wherein the actuating mechanism is used for driving the push rod 2, and the push rod 2 drives the external-open handle 4 to horizontally extend out and retract; the controller is used for acquiring the power-on state of the feedback mechanism and determining the motion state of the outward opening handle 4 according to the power-on state; when the motion state of the outward opening handle 4 is a horizontal-out limit state or a back-out limit state, the controller is also used for feeding back a target signal for stopping driving the push rod 2 to the actuating mechanism; the actuator stops driving the push rod 2 based on the target signal.
Compared with the pure mechanical limiting mode in the traditional mode, the control mode of the externally-opened handle 4 has the difference and the advantage that the power of the actuating mechanism can be controlled to be cut off at the first time when the externally-opened handle 4 reaches the horizontal-out or backward-moving limit position, the traditional mechanical limiting mode usually carries out mechanical limiting on the moving position of the externally-opened handle 4 or controls the working time of the actuating mechanism so as to control the horizontal-out and backward-moving limit positions of the externally-opened handle 4, and the mode can achieve the purpose of controlling the externally-opened handle to move to the specified position, but the control precision of the actuating mechanism on the externally-opened handle 4 is low, namely after the externally-opened handle 4 reaches the specified position and is limited, the actuating mechanism can still output torque within a certain time, and the internal rotation blockage of the actuating mechanism can be caused to damage at the moment.
It is understood that the controller may be a vehicle body controller, and the horizontal-out limit state and the retraction limit state are preset limit position states of the movement of the two outward-opening handles 4, the horizontal-out limit state may be understood as the state where the outward-opening handles 4 are just horizontally out to the preset limit position outside the vehicle door, and the retraction limit state is the state where the outward-opening handles 4 are just retracted to the preset limit position inside the vehicle door.
It should be further noted that the feedback mechanism in this embodiment includes a first signal feedback mechanism and a second signal feedback mechanism, and the controller determines the motion state of the open handle 4 by acquiring the power-on or power-off state signals of the first signal feedback mechanism and the second signal feedback mechanism, specifically:
when the energization state of the first signal feedback mechanism is an energization connected state and the energization state of the second signal feedback mechanism is an energization connected state, it is determined that the movement state of the out-opening handle 4 is a leveling-out limit state; when the power-on state of the first signal feedback mechanism is the power-on off state and the power-on state of the second signal feedback mechanism is the power-on off state, determining that the motion state of the outward opening handle 4 is the retraction limit state;
when the power-on state of the first signal feedback mechanism is a power-on state and the power-on state of the second signal feedback mechanism is a power-off state, determining that the motion state of the outward opening handle 4 is an intermediate state; when the controller is in the intermediate state, the controller continuously acquires the power-on state of the feedback mechanism until the movement limit state or the fault state of the outward opening handle 4 is acquired;
when the power-on state of the first signal feedback mechanism is a power-on off state and the power-on state of the second signal feedback mechanism is a power-on state, it is determined that the motion state of the external-open handle 4 is a fault state, and when the motion state of the external-open handle is a fault state, the controller is further configured to output a signal representing a fault of the external-open handle, it is understood that the fault state further includes other states, for example, when the first signal feedback mechanism is in the power-on state and the second signal feedback mechanism is in the power-off state, the holding time of the overall states of the first signal feedback mechanism and the second signal feedback mechanism is longer than a preset time (for example, 30 s), then it can be inferred that the internal-open handle 4 does not level out to a preset limit position within 30s, and the controller also outputs a fault signal outwards at this time, in this case, it can be inferred that an obstacle exists on the motion path of the external-open handle, and the fault state can be inferred to be similar.
For the sake of easy understanding, the above technical solution is now described with reference to a specific embodiment:
as shown in fig. 1-13, a hidden external-open handle limit structure comprises a controller, an actuating mechanism, a first signal feedback mechanism, a second signal feedback mechanism, a push rod 2 and an external-open handle 4, wherein the actuating mechanism drives the push rod 2 to reciprocate, the reciprocating motion of the push rod 2 drives the external-open handle 4 to horizontally move out and back, the controller judges whether the external-open handle 4 moves to the horizontal-out or back-back limit position by acquiring the power-on and power-off states of the first signal feedback mechanism and the second signal feedback mechanism which are fixed on a base 8, and when the external-open handle 4 is judged to be at the limit position, the controller controls an actuator to stop driving the push rod 2 to move.
Specifically, the automobile door further comprises a base 8, a first rotating arm 7 and a second rotating arm 3 are arranged at the two ends of the base 8 respectively, the two ends of the first rotating arm 7 are connected with one end of an outward opening handle 4 and a connecting arm 6 respectively, one end of the second rotating arm 3 is connected with the other end of the outward opening handle 4 through a shaft pin, and the base 8 is connected to the automobile door main body through a bolt. It will be understood that the push rod 2 is slidably connected to the base 8, and it should be noted that the out-swinging means that the out-swinging handle 4 is extended in parallel movement relative to the vehicle door.
In this embodiment: the first signal feedback mechanism comprises a first switch 5-1 and a first reed 5-3, the second signal feedback mechanism comprises a second switch 5-2 and a second reed 5-4, and preferably, the first switch 5-1 and the second switch 5-2 are both microswitches; the actuating mechanism comprises a driving motor 1, a screw rod and a nut, the nut is arranged on the base 8, one end of the screw rod is fixedly connected with the output end of the driving motor 1, and the other end of the screw rod is connected with the push rod 2.
As shown in fig. 10-12, the push rod 2 is further provided with a first limiting rib 2-1 and a second limiting rib 2-2, which are used in cooperation with the first switch 5-1 and the second switch 5-2, wherein the first limiting rib 2-1 and the second limiting rib 2-2 are arranged in parallel on the push rod 2, the push rod 2 is used to push and squeeze the first reed 5-3 and the second reed 5-4 when moving, when the first limiting rib 2-1 squeezes the first reed 5-3, the first reed 5-3 transmits the acting force to the first switch 5-1 to electrify the first switch 5-1, and when the second limiting rib 2-2 squeezes the second reed 5-4, the second reed 5-4 transmits the acting force to the second switch 5-2 to electrify the second switch 5-2, and similarly, when the first limiting rib 2-1 is separated from the first reed 5-3, the first reed 5-3 loses the extrusion acting force on the first switch 5-1, the first switch 5-1 is powered off, when the second limiting rib 2-2 is separated from the second reed 5-4, the second reed 5-4 loses the extrusion acting force on the second switch 5-2, the second switch 5-2 is powered off, and it is not difficult to understand that in order to realize the interval triggering of the first switch 5-1 and the second switch 5-2, when the first switch 5-1 and the second switch 5-2 are installed side by side, the length of the first limiting rib 2-1 should be greater than that of the second limiting rib 2-2, of course, in this embodiment, the first switch 5-1 is triggered by other methods, the second switch 5-2, the first limiting rib 2-1 and the second limiting rib 2-2 are arranged, so that the effect of the matched use is consistent with the effect in the technical scheme.
It can be seen that the principle that the outward-opening handle is leveled out in the technical scheme is as follows: when the handle receives an extension instruction sent by the whole vehicle, the actuating mechanism pushes the push rod 2 to move, while the push rod 2 moves, the tail end of the push rod 2 abuts against the second rotating arm 3, the front end of the push rod is in surface contact with the first rotating arm 7, so that the second rotating arm 3 and the first rotating arm 7 move along a fixed track and rotate around the central shaft to drive the motion track of the external opening handle 4 to be leveled out, in the specific implementation mode, the push rod 2 moves from the beginning, the first limiting rib 2-1 arranged on the push rod extrudes the first reed 5-3, the first reed 5-3 extrudes the first switch 5-1 again, and therefore the first switch 5-1 is electrified, at the moment, the vehicle body controller ignores the signal, and can also understand that the actuating mechanism is moving when the first switch 5-1 is electrified, namely, the external opening handle 4 is in an intermediate state; if the external-open handle 4 is leveled out to the preset limit position, the second limiting rib 2-2 extrudes the second reed 5-4 at the moment, namely the second reed 5-4 extrudes the second switch 5-2, so that the second switch 5-2 is electrified, the vehicle body controller acquires the signal and sends a target signal to the actuating mechanism, and the target signal refers to the leveling-out of the external-open handle 4 to the preset limit position, so that the actuating mechanism is controlled to be powered off.
Meanwhile, the principle of the retraction of the external-open handle 4 is as follows: when the vehicle body controller receives a signal of the retreating of the external opening handle 4, for example, when a vehicle door is completely closed or a vehicle is in a traveling process, a retreating signal of the external opening handle 4 is sent, at this time, the actuating mechanism is reversed, and a reversed process when the external opening handle 4 is laid out is executed, it is to be specially described that when the external opening handle 4 starts to perform retreating movement, the second limiting rib 2-2 is separated from the second reed 5-4, that is, the second switch 5-2 is powered off, the vehicle body controller ignores the signal, that is, the external opening handle 4 is in a middle state until the push rod 2 retreats to a preset limit position, at this time, the first limiting rib 2-1 is separated from the first reed 5-3, that is, the first switch 5-1 is powered off, the vehicle body controller acquires the signal, and feeds back a signal of stopping driving the push rod to the actuating mechanism.
As shown in fig. 3-6, in an alternative embodiment, an auxiliary mechanism for triggering a glass lifting signal and a door lock unlocking signal is further disposed on the first rotating arm 7, and the auxiliary mechanism includes a connecting arm 6, a connecting arm torsion spring 9, a control rod 10 and a control rod torsion spring 11, wherein the control rod 10 is connected to the base 8 through a shaft pin, when the out-opening handle 4 extending to the extreme position state is pulled outwards, the out-opening handle 4 drives the first rotating arm 7, the connecting arm 6 and the control rod 10 to rotate around the rotating shaft 6-2, and an edge profile of the control rod 10 contacts with a glass short-drop switch and a door lock unlocking switch disposed inside the door to trigger the glass short-drop signal and the door lock unlocking signal, which are specifically referred to as the glass short-drop signal and the door lock unlocking signal; the control rod torsion spring 11 and the connecting arm torsion spring 9 are used for controlling the reset of the external force released by the external-open handle 4. Specifically, when the outward opening handle is unfolded, the connecting arm 6 does not rotate, the push rod 2 pushes the first rotating arm 7 to rotate, the outward opening handle 4 is continuously pulled after the outward opening handle 7 is unfolded to a limit position, the outward opening handle 4 drives the first rotating arm 7, the connecting arm 6 and the control rod 10 to rotate, a glass short-falling signal and a door lock unlocking signal are triggered, and the signal controls a specific actuating mechanism in a door to enable the door glass to be unfolded with a door lock.
As shown in fig. 7, 8 and 13, it can be easily seen that an installation through groove is formed in one end of the base 8 where the first switch 5-1 and the second switch 5-2 are installed, the first switch 5-1 and the second switch 5-2 are arranged in the installation through groove, the first limiting rib 2-1 and the second limiting rib 2-2 are arranged on the push rod 2 below the installation through groove, an installation seat is arranged inside the installation through groove, the first switch 5-1 and the second switch 5-2 are installed in the installation seat, and one ends of the first reed 5-3 and the second reed 5-4 are clamped on the installation seat, so that the connection between the first switch 5-1 and the second switch 5-2 and the base 8 is simpler and more reliable.
As shown in fig. 1, it should be further described that a boss is disposed at one end of the push rod 2 facing the second rotating arm 3, and a slope is disposed at a position where the second rotating arm 3 contacts the boss, such that when the push rod 2 moves, the push rod 2 and the second rotating arm 3 are always in line contact, thereby preventing abnormal friction noise.
