It will be understood by those skilled in the art that the foregoing definitions are for convenience of description only and not for limitation of the present invention, and that the definitions of front, back, left, right and other directions of the present invention shall be based on actual technical features and technical solutions, rather than only with reference to the text definitions, so that the definitions of the front door, the back door, etc. of the present invention are relative.

Referring to fig. 1, the utility model discloses a no stand door locking system, this structure are particularly useful for the no guide rail motorcycle type, can improve the security of being connected between door and the frame greatly.

In an embodiment of the present invention, the utility model discloses a no stand door locking system, including door, door Control Unit (DCU) 200, drive unit 100, the door includes first door 300 and second door 400, drive unit 100 is connected to door control unit 200, the side that first door 300 is close to second door 400 is pressed on the side of second door 400, drive unit 100 drives the connecting rod and makes first door 300, second door 400 close or open with the mode of no guide rail translation, the back side of first door 300 and the preceding side of second door 400 interlock in the middle part of the automobile body when first door 300 and second door 400 are closed.

Specifically, the first door 300 includes a first front lock 310, a first day lock 320, and a first ground lock 330, the first front lock 310 interlocks a front side of the first door 300 with a front portion of the frame 500, the first day lock 320 interlocks a top portion of a rear side of the first door 300 with a top portion of the frame 500, and the first ground lock 330 interlocks a bottom portion of the rear side of the first door 300 with a bottom portion of the frame 500. The second door 400 includes a second front lock 410, a second rear lock 420, the second front lock 410 interlocking a front side of the second door 400 with a rear side of the first door 300, the second rear lock 420 interlocking a rear side of the second door 400 with a rear portion of the frame 500.

The door control unit 200 can control the opening or closing of the first front lock 310, the first day lock 320, the first ground lock 330, the second front lock 410 and the second rear lock 420, so as to open/close only the first vehicle door and only the second vehicle door, and simultaneously open/close the first vehicle door and the second vehicle door.

Therefore, the first door and the second door are interlocked in the middle, and the first door and the second door are respectively interlocked with the frame, so that the safety between the first door and the second door can be greatly improved.

It will be appreciated by those skilled in the art that the benefits of interlocking the rear side edge of the first door 300 with the front side edge of the second door 400 at the center of the vehicle body by the latch mechanism are not the same as those of interlocking the door with the vehicle body by the latch mechanism of the prior art, which would not suggest this solution.

In the prior art, because the door is connected with the frame through the hinge or the guide rail, the necessity of the door locking device is not high, namely, the door locking device can be available or unavailable in the connection of the door and the frame, and the problem of door locking can be completely solved by arranging a limiting structure on the hinge and the guide rail. In particular, the prior art does not require interlocking of a first door (e.g., a front door of an automobile) and a second door (e.g., a rear door of an automobile) because the first door and the second door are each interlocked with the frame. Specifically, in the prior art, a lock body is disposed on a side edge of the first door, and a latch is disposed on the B-pillar of the vehicle, so that when the first door is closed, the lock body on the side edge and the latch of the B-pillar are interlocked, thereby achieving locking of the door. The second door is the same.

Especially in the aspect of safety, because the vehicle door in the prior art, namely the first door and the second door, has the upright column (B column), the safety problem between the doors of the vehicle without the upright column (B column) does not need to be considered, and the safety between the door and the vehicle body does not need to be considered too much, namely when the vehicle has a side collision, because of the existence of the upright column (B column), the collision force on the side can be transmitted to the vehicle body through the B column, and then the vehicle body absorbs a large amount of energy generated by the collision force through the upright column (B column), so that the safety of passengers is ensured while the injury is caused by the side collision.

However, in the case of a pillar-less (B-pillar-less) vehicle, the need for a locking mechanism is required for the connection between the first door and the second door due to the change in the pillar-less structure, i.e., the safety between the doors must be further improved by enhancing the locking between the first door and the second door. If the door is locked with the vehicle body without a locking mechanism between the doors, the joint of the first door and the second door becomes the weakest place of the whole door due to the lack of specific collision force transmission between the doors in the event of a side collision, and the joint of the first door and the second door is subjected to large door deformation in the event of collision, thereby endangering the safety of passengers.

Therefore, the door locking mechanism is arranged between the first door and the second door, so that the impact force transmission of the door when the door receives the side impact force can be influenced, the impact energy of the door is greatly absorbed, the deformation of the door is reduced, and the safety of the joint of the first door and the second door is greatly enhanced.

Therefore, for the automobile without a pillar (without a B pillar), a locking device between the doors is necessary, and by arranging a locking mechanism between the first door and the second door, the safety of the doors can be greatly improved, and the deformation of the doors when the automobile is subjected to a side collision can be greatly reduced. Similarly, it is not obvious that the locks between the front side, the upper side and the lower side of the vehicle door and the vehicle frame are arranged on the vehicle door, and a set of relatively good fixing modes and collision energy absorption paths of the vehicle door and the vehicle frame can be formed through the combination of the first front lock 310, the first day lock 320 and the first ground lock 330 and through the combination of the second front lock 410 and the second rear lock 420, so that the collision energy can be effectively transferred and conducted to the vehicle body when the vehicle is laterally collided.

In particular, the first front lock 310, the first day lock 320, and the first ground lock 330 are not meant to be opened/closed at the same time, and similarly, the second front lock 410 and the second rear lock 420 are not meant to be opened/locked at the same time. For example, in an embodiment where the side of the first door adjacent the second door presses against the side of the second door adjacent the first door, the first door is closed and the second door is opened with the second rear lock first opened, and then the second door is rotated along the first door by a certain angle before the second front lock is opened. Similarly, when the first door is closed, the first day lock and the second ground lock are firstly opened, and then the first front lock is opened after the first door rotates for a certain angle along the second door.

It should be understood by those skilled in the art that the first door and the second door are not limited in position, but only in terms of mechanical structure, for example, when the first door is a front door and the second door is a rear door, the side of the first door adjacent to the second door presses against the side of the second door adjacent to the first door is "front door pressing rear door", and the side of the first door adjacent to the second door presses against the side of the second door adjacent to the first door is "rear door pressing front door", and when the first door is a rear door and the second door is a front door, the state is changed accordingly.

As the above-mentioned embodiment of "front door-pressed rear door", it is mainly different from the prior art in that the front door can be made to be in a closed (locked) state, and the rear door can be made to be opened alone.

In the present embodiment, when the rear door needs to be opened separately, the door control unit 200 receives the door opening operation signal and unlocks the second front lock 410 and the second rear lock 420 of the second door 400 according to the door opening operation signal. At this time, the first front latch 310, the first day latch 320, and the first ground latch 330 remain in the latched state, so that the first door 300 remains in the closed state. After unlocking, the door control unit 200 drives the second door 400 by the driving unit 100 to be opened individually toward the rear of the vehicle in a translational or sliding manner.

As the above-mentioned embodiment of "rear door-pressure front door", it is mainly different from the prior art in that the front door can be opened alone in a state where the rear door is closed (locked).

In the present embodiment, when the front door needs to be opened separately, the door control unit 200 receives the door opening operation signal, and unlocks the first front lock 310, the first day lock 320, the first ground lock 330, and the second front lock 410 of the first vehicle door 300 according to the door opening operation signal. At this time, the second rear latch 420 remains in the latched state, so that the second door 400 remains in the closed state. After unlocking, the door control unit 200 drives the first door 300 to be opened alone toward the front of the vehicle in a translational or sliding manner by the driving unit 100.

In addition, no matter the mode of "the back door is pressed to the front door" or "the back door presses the front door", the utility model discloses a first door 300 and second door 400 all can realize opening simultaneously.

In the present embodiment, when two doors need to be opened simultaneously, the door control unit 200 receives the door opening operation signal and unlocks all the locks according to the door opening operation signal, that is, unlocks the first front lock 310, the first day lock 320, the first ground lock 30, the second front lock 410, and the second rear lock 420 simultaneously. After unlocking, the door control unit 200 drives the first door 300 to open toward the front of the vehicle in a translational or sliding manner and drives the second door 400 to open toward the rear of the vehicle in a translational or sliding manner by the drive unit 100.

In particular, one end of the connecting rod is connected with the vehicle frame, the other end of the connecting rod is connected with the vehicle door, in certain specific embodiments, the connecting rod is in a specific shape, the shape is matched with the sliding motion track of the vehicle door,

further, the connecting rod can be more than one, for example two or more, in a specific embodiment of the present invention, there are two connecting rods, that is, the first connecting rod 600 and the second connecting rod 610, the first connecting rod 600 is connected to the middle of the vehicle door by the vehicle frame to provide the main driving power, and the second connecting rod 610 is connected to the bottom or the top of the vehicle door by the vehicle frame to mainly adjust the angle deflection or the auxiliary connection of the vehicle door.

As an embodiment of the present invention, the connecting rods include a first connecting rod 600 and a second connecting rod 610, the first connecting rod 600 is a specific bending connecting rod, one end of the first connecting rod 600 is connected to the frame, the other end is connected to the middle part of the inner side of the vehicle door, the first connecting rod 600 is provided with a driving motor, and the first connecting rod 600 can be electrically controlled to complete the opening of the vehicle door; the second link 610 is a partially deformable link, and one end of the second link 610 is connected to the bottom of the frame and the other end is connected to the inner bottom of the door. When the side of the first door close to the second door is pressed on the side of the second door close to the first door, the first door is closed, and only the second door is opened, the second rear lock is opened, the second door deflects by a certain angle, at this time, the second link 610 deforms appropriately, the second link 610 lengthens, the driving device can adapt to the deflection motion of the second door, after the second door completes the deflection motion, the second front lock is opened, the second door moves along the deflection angle under the driving of the first link 600, and simultaneously, under the restoring force of the second link 610, the second link 610 gradually restores the state before the deformation, and accordingly, the second link 610 drives the second door to complete the appropriate angle deviation. In other words, during the opening of the second door in this embodiment, the second door is first deflected by a certain angle, and then starts to move along the angle while rotating in the opposite direction by a certain angle due to the restoring force of the second link 610, and finally, the door is opened in a state where the door is nearly parallel to the vehicle frame.

It should be understood by those skilled in the art that the vehicle door can be opened/closed in a non-guideway sliding manner in a plurality of manners besides the link manner, and as long as the vehicle door can be opened/closed in a non-guideway sliding manner, the vehicle door can be considered as an embodiment of the present solution.

As shown in fig. 2 and 3, since the first door 300 and the second door 400 are opened/closed in a translational or sliding manner, this means that the first door 300 and the a-pillar are not fixedly connected by a hinge, and similarly, the second door 400 and the C-pillar are not fixedly connected by a hinge.
