It should be noted that in different drawings, the same reference numerals indicate the same or substantially the same components.
Referring to fig. 8, the rear side edge of the front door 12 in this application has a flange 121 and a sealing strip 122, the sealing strip 122 being provided inside the flange 121, the sealing strip 122 having a groove into which the front side edge 91 of the sliding door is inserted.
As shown in fig. 1, 2a, and 7, a side-sliding door apparatus according to a preferred embodiment of the present invention includes: a linear driving mechanism 7, a first hinge 2, a second hinge 3, a third hinge 4, a fourth hinge 5, a first link 1, a second link 6, a door frame 8 having an entrance and an exit, and a sliding door 9 for covering the entrance and the exit. The door frame 8 is a part of an automobile frame and is specially used for installing a door, and an access port on the door frame 8 is used for a user to access the automobile.
Opposite ends of the first hinge 2 are respectively and rotatably connected with the door frame 8 and the first connecting rod 1; opposite ends of the second hinge 3 are respectively and rotatably connected with the door frame 8 and the second connecting rod 6;
opposite ends of the third hinge 4 are rotatably connected to the sliding door 9 and the first link 1, respectively. The fourth hinge 5 includes: a first rotating body 51 and a first rotating shaft 52. The first rotating body 51 is provided with a first chute 511, and the first chute 511 extends away from the sliding door 9. The rotating shaft is slidably disposed in the first chute 511. The first rotating body 51 is fixedly connected with the door frame 8, and the first rotating shaft 52 is rotatably connected with the second connecting rod 6, so that the door and the second connecting rod 6 are rotatably connected through the second connecting rod 6.
The connecting line between the first rotating shaft 52 and the sliding door 9 is a preset distance, the output shaft of the linear driving mechanism 7 is rotationally connected with the first rotating shaft 52, and the linear driving mechanism 7 is used for driving the first rotating shaft 52 to slide in the first sliding groove 511, so that the length of the preset distance is changed.
The sliding door 9 is movable relative to the doorway so that the sliding door 9 has a closed state and an open state. The sliding door 9 before the present application achieves the opening and closing of the sliding door 9 by means of translation, and the sliding door 9 is always parallel to the door frame 8.
In order to enable the sliding door 9 to tilt relative to the door frame 8, the rotation axis of the first hinge 2 and the rotation axis of the third hinge 4 are offset, and the rotation axis of the second hinge 3 and the first rotation axis 52 are offset.
By changing the preset distance, the first hinge 2, the second hinge 3, the third hinge 4 and the first rotating shaft 52 form different four-bar structures, and the change of the preset distance enables the virtual connecting bar length between the first rotating shaft 52 and the third hinge 4 to be changed, so that the sliding door 9 can have different movement tracks. The different motion trajectories of the sliding door 9 are embodied in such a way that the sliding door 9 is parallel to the door frame 8 or is inclined to the door frame 8, so that the sliding door 9 can have more motion trajectory selections when opening and closing the door.
Wherein the linear driving mechanism 7 is used for driving the first rotating shaft 52 to slide in the first sliding chute 511 so as to enable the rotating shaft to approach to or separate from the sliding door 9. The sliding door 9 is parallel to the door frame 8, so that the sliding door 9 just covers the doorway, the sliding door 9 and the door frame 8 are inclined, the rear side edge 92 of the sliding door is separated from contact with the rear side edge of the doorway in the door opening process, and then the front side edge 91 of the sliding door is separated from the sealing strip 122 of the rear side edge of the front door 12 in an inclined manner, so that collision between the sliding door 9 and the flanging 121 of the front door 12 is avoided.
In a possible embodiment, the linear driving mechanism 7 is a cylinder, and the cylinder is fixedly disposed on the sliding door 9, the rotation axis of the first hinge 2, the rotation axis of the second hinge 3, the rotation axis of the third hinge 4, and the first rotation axis 52 all extend in a vertical direction, and the first chute 511 extends in a horizontal direction, so that the sliding door 9 can be opened and closed in the horizontal direction. The output shaft of the cylinder expands and contracts in the horizontal direction, so that the cylinder can drive the first rotating shaft 52 to slide in the first sliding groove 511.
Further, the embodiment of the invention further comprises: a second driving mechanism; the second driving mechanism is used for driving the first hinge 2 to rotate.
Specifically, the second driving mechanism may be a motor, which is disposed on the door frame 8, and an output shaft of the motor is coaxially connected with the rotation shaft of the first hinge 2, so as to drive the first link 1 to rotate by driving the first hinge 2 to rotate, thereby driving the second link 6 to be driven.
Referring to fig. 2a, in one embodiment of the first sliding grooves 511, the first sliding groove 511 is a straight sliding groove extending along a predetermined straight direction; the predetermined straight direction is perpendicular to the sliding door 9.
Referring to fig. 2b, in another embodiment of the first sliding chute 511, the first sliding chute 511 is an arc-shaped sliding chute; the arc chute is recessed toward the second hinge 3, and the arrangement of the arc chute enables a greater range of relative angular movement of the front side edge 91 of the sliding door and the door frame 8.
Referring to fig. 8, in the present application, the front side edge 91 of the sliding door 9 is clamped in the sealing strip 122 of the front door 12, if the sliding door is opened by a connecting rod, the sliding door 9 is turned outwards, that is, the sliding door 9 is turned over by the connecting rod in a larger angle than the sliding rail is arranged on the outer wall of the vehicle door, if the front door 12 is provided with the flange 121 and the sealing strip 122, the sliding door 9 will collide with the flange 121 in the opening process, so that the front side edge 91 of the sliding door 9 cannot be separated from the groove body of the sealing strip 122. Meanwhile, the sliding door 9 is opened by adopting a connecting rod, and the rear side edge 92 of the sliding door is collided with the rear side edge 82 of the door frame.
Based on the above-described problems, the present application has been improved, and examples for solving the above-described problems will be given below.
Referring to fig. 7, an end of the first sliding groove 511 near the sliding door 9 is a first position 10, and an end of the first sliding groove 511 far from the sliding door 9 is a second position 11. The distance between the first pivot 52 and the third hinge 4 is a first predetermined distance when the first pivot 52 is in the first position 10, and the distance between the first pivot 52 and the third hinge 4 is a second predetermined distance when the first pivot 52 is in the second position 11. The second preset distance is greater than the first preset distance, and by the change of the preset distance, different four-bar structures are formed among the first hinge 2, the second hinge 3, the third hinge 4 and the first rotating shaft 52, and the change of the preset distance enables the virtual connecting bar between the first rotating shaft 52 and the third hinge 4, so that the sliding door 9 can have different movement tracks. The movement locus of the sliding door 9 will be explained below. Wherein the sliding door 9 in both the door-closed state and the door-open state is parallel to the door frame 8.
During the switching of the sliding door 9 from the closed state to the open state:
referring to fig. 2a, 2b and 3, fig. 2a and 2b are a door-closed state, fig. 3 is a first state, fig. 4 is a second state, and fig. 5 is a door-open state. When the sliding door 9 is in the closed state and the first rotating shaft 52 is located at the first position 10, the second motor drives the second hinge 3 to rotate, so as to drive the sliding door 9 to switch from the closed state to the first state (from the state of fig. 2 to the state of fig. 3), and during the switching process, the rear side edge 92 of the sliding door rotates around the front side edge 91 of the sliding door, so that the sliding door 9 and the door frame 8 tilt. In the first state, the front edge 91 of the sliding door is attached to the front edge 81 of the door frame, the rear edge 92 of the sliding door is detached from the rear edge 82 of the door frame, in the process that the sliding door 9 is switched from the closed state to the first state, the rear edge 92 of the sliding door is detached from the rear edge 82 of the door frame first, the problem that collision occurs between the rear edge 92 of the sliding door and the rear edge of the entrance can be solved, meanwhile, as the sliding door 9 is inclined to the door frame 8 at this time, a certain angle exists between the front edge of the sliding door 9 and the flanging 121 of the front door 12, the sliding door 9 can be better detached from the groove body of the sealing strip 122, and the problem that if a connecting rod door is adopted, the front edge of the sliding door 9 needs to be turned outwards first, and the front edge of the sliding door 9 cannot be detached from the groove body of the sealing strip 122 due to collision of the flanging 121 of the front door 12 is solved.
Referring to fig. 3 and 4, in order to avoid a situation that the sliding door 9 is inclined with respect to the door frame 8, so that the occupied space is large after the sliding door 9 is opened, when the sliding door 9 is in the first state, the first rotating shaft 52 is located at the first position 10, and the cylinder 71 drives the first rotating shaft 52 to switch from the first position 10 to the second position 11, so as to drive the sliding door 9 to switch from the first state to the second state (from the state of fig. 3 to the state of fig. 4), that is, the sliding door 9 in the first state, in which the sliding door 9 is inclined with respect to the door frame 8 to the second state, is parallel to the door frame 8.
Referring to fig. 4 and 5, when the sliding door 9 is in the second state, the first rotating shaft 52 is located at the second position 11, and the second motor drives the second hinge 3 to rotate, so that the sliding door 9 is switched from the second state to the door opening state (from the state of fig. 3 to the state of fig. 5), and the second state to the door opening state is a state in which the sliding door 9 is completely opened.
During the process of switching the sliding door 9 from the door-open state to the door-closed state:
referring to fig. 4 and 5, when the sliding door 9 is in the door-open state and the first rotating shaft 52 is located at the second position 11, the second motor drives the second hinge 3 to rotate, so that the sliding door 9 is switched from the door-open state to the second state (from the state of fig. 5 to the state of fig. 4).
Referring to fig. 3 and 4, when the sliding door 9 is in the second state, the first rotating shaft 52 is located at the second position 11, the cylinder 71 drives the first rotating shaft 52 to switch from the second position 11 to the first position 10, so as to drive the sliding door 9 to switch from the second state to the first state (from the state of fig. 4 to the state of fig. 3), during the switching process, the front side edge 91 of the sliding door is firstly attached to the front side edge 81 of the door frame, and the rear side edge 92 of the sliding door is in a disengaged state with the rear side edge 82 of the door frame. That is, when the sliding door 9 is in the first state, the sliding door 9 is inclined with the door frame 8. The front edge 91 of the sliding door is first inclined to be clamped into the groove of the rear edge sealing strip 122 of the front door 12, so that the problem that the front edge 91 of the sliding door cannot be clamped into the groove of the rear edge sealing strip 122 of the front door 12 can be avoided.
Referring to fig. 3, when the sliding door 9 is in the first state, the first rotating shaft 52 is located at the first position 10, and the second motor drives the first hinge 2 to rotate, so as to drive the sliding door 9 to switch from the first state to the closed state (from the state of fig. 3 to the state of fig. 2a and 2 b). During the switching, the rear side edge 92 of the sliding door is turned around the front side edge 91 of the sliding door so that the sliding door 9 is parallel to the door frame 8 and the rear side edge 92 of the sliding door is brought into abutment with the rear side edge 82 of the door frame. After the front edge 91 of the sliding door is first obliquely snapped into the channel of the rear edge sealing strip 122 of the front door 12, the rear edge 92 of the sliding door is then attached to the rear edge 82 of the door frame, so that the front edge 91 of the sliding door and the rear edge 92 of the sliding door can be prevented from being attached to the front edge 81 of the door frame and the rear edge 82 of the door frame at the same time, thereby causing the front edge 91 of the sliding door or the rear edge 92 of the sliding door to tilt.
In summary, in the process of switching the sliding door 9 from the door closing state to the door opening state, the embodiment of the invention can solve the problem that the sliding door 9 collides with the flange 121 in the opening process due to the flange 121 and the sealing strip 122 provided on the front door 12 when the sliding door is opened by adopting the connecting rod to open the door. In the process of switching the sliding door 9 from the door opening state to the door closing state, the front side edge 91 of the sliding door is firstly inclined and clamped into the groove body of the rear side edge sealing strip 122 of the front door 12, so that the problem that the front side edge 91 of the sliding door cannot be clamped into the groove body of the rear side edge sealing strip 122 of the front door 12 can be avoided, and the front side edge 91 of the sliding door and the rear side edge 92 of the sliding door are prevented from being simultaneously attached to the front side edge 81 of the door frame and the rear side edge 82 of the door frame, so that the front side edge 91 of the sliding door or the rear side edge 92 of the sliding door is prevented from being tilted.
Specifically, the present application has a control system for controlling the operation sequence of the cylinder 71 and the second driving mechanism.
Further, the rotation axis of the first hinge 2 and the rotation axis of the third hinge 4 are arranged in a staggered manner. The rotation shaft of the second hinge 3 and the first rotation shaft 52 are arranged in a staggered manner.
The present invention also provides an automobile comprising: a side-sliding door apparatus as claimed in any one of the preceding claims.
