Example 1
Referring to fig. 1, the door connecting device includes a stopper 30 provided at a first connecting point 1 and a door lock provided at a second connecting point 2.
As a preferred embodiment, the stop device 30 and the door lock are disposed at the original B-pillar position of the vehicle body structure, and the stop device 30 and the door lock are disposed in the door up-down direction for bearing the load under the side impact condition.
The door connecting device of the present embodiment is described in detail below, and with reference to fig. 1 and 2, includes: the automobile door comprises a door body 10 and a door lock and limiting device 30, wherein the door lock and limiting device 30 is arranged at the original B column position, and the door lock is arranged at the lower part of the door body 10 and is used for connecting a vehicle body structure 40 and the door body 10 when the door is closed; the door lock is also used to lock the door and prevent the door body 10 from opening under load impact.
Specifically, the limiting device 30 includes a limiting member 301 and a clamping structure 302 matched with the limiting member 301, and under a side impact condition and/or a closed state of the vehicle door, the limiting member 301 and the clamping structure 302 are clamped, so that the vehicle door body 10 is connected with the vehicle body structure 40.
Further, the limiting device 30 further comprises an actuating device, and the actuating device is used for driving the limiting member 301 and the clamping structure 302 to be clamped or separated. Specifically, the starting device may be configured to provide a driving force for moving the position of the limiting member 301 within a limited range, so that the limiting member 301 is engaged with the engaging structure 302.
In some embodiments, the starting device may be configured to change the position of the trigger paddle when the vehicle door is closed, so that the position of the limiting member 301 is changed, and the limiting member 301 is engaged with the engaging structure 302. In some other embodiments, the starting device may also be an electric control device, and the electric control device may include a sensor for sensing an opening/closing state of the vehicle door and an executing component, and when the vehicle door is sensed to be closed, the executing component changes a relative displacement or a relative angle between the limiting member 301 and the engaging structure 302, so that the limiting member 301 and the engaging structure 302 are automatically engaged when the vehicle door is closed.
As a possible embodiment, the limiting means 30 is provided as a mating structure of a pin and a socket. As shown in fig. 2, the stopper 301 may be provided as a latch, including a pin and a pin cap, and provided at an upper portion of the door body 10. Correspondingly, a pin hole is arranged at a position opposite to the vehicle body structure 40 as a clamping structure 302, and the pin hole is matched with the pin of the limiting piece 301 and is used for connecting the door body 10 and the vehicle body structure 40 under the condition of closing or side collision of the door.
As another possible embodiment, the limiting member 301 may be disposed on the vehicle body structure 40, and accordingly, the latch structure 302 may be disposed on the door body 10 to perform the same connecting function.
Considering that the door lock may be disposed at the upper portion of the door body 10, i.e. at the position of the first connection point 1, in practical applications, it will be understood by those skilled in the art that the design in which the position-limiting device 30 is disposed at the second connection point 2, at the lower portion of the door, has the same effect as the door lock at the lower portion and the position-limiting device 30 at the upper portion.
In addition, the same effects as those described above can be obtained by adding another door lock to the original door lock and separately installing the door lock on the upper portion and the lower portion of the door body 10, but the stopper device 30 of the present embodiment has a simple structure in consideration of the light weight design, and the configuration of the present embodiment is more applicable particularly to a vehicle without a B-pillar and in which the installation space is limited.
As a further improved embodiment, referring to fig. 3 and 4, when the door is closed, the pin provided with the stopper 301 is disengaged from the vehicle body structure, and when a load collision occurs, the pin of the stopper 301 is engaged with the engaging structure 302 under the load action by the guiding arrangement of the stopper 301 and the engaging structure 302, so that the vehicle body structure 40 is effectively connected with the door body 10, thereby resisting the load and reducing the intrusion of the door. For example, the stopper 301 may be engaged with the latch structure 302 under load by designing the opening of the stopper 301 in the door body 10 and by designing the pin hole of the latch structure 302 to guide the pin. The limiting device 30 of this example can further solve the problem that collision noise may exist during the driving process when the limiting member 301 and the clamping structure 302 are clamped after the vehicle door is closed.
As another possible implementation manner, referring to fig. 5 and 6, the starting device is configured as an electromagnetic driving unit 311, and the limiting device 30 further includes an elastic member 310, where the elastic member 310 is connected between the electromagnetic driving unit 311 and the limiting member 301; the door connecting device further includes a controller and a detector, the detector is disposed on the door body 10, the detector can select a pressure sensor for detecting the door collision pressure, and the controller is electrically connected to the electromagnetic driving unit 311 for controlling the electromagnetic driving unit 311 according to the collision pressure.
Further, the controller further comprises: the pressure detection module is used for detecting the collision pressure of the vehicle door; and the control module is used for acquiring the collision pressure and judging whether to start the starting device according to a preset pressure threshold value.
As will be described with reference to a specific application scenario, when the door is closed, the electromagnetic driving unit 311 is attracted to the position-limiting member 301, the pin of the position-limiting member 301 is disengaged from the latching structure 302, and the vehicle body structure 40 is connected to the door body 10 through the door lock.
When the detector detects that the collision pressure on the vehicle door is higher than a preset pressure threshold value, the controller controls the current of the electromagnetic driving unit 311 to reduce the magnetic attraction, so that the limiting piece 301 is far away from the electromagnetic driving unit 311, the limiting piece 301 moves towards the clamping structure 302, the pin is clamped with the clamping structure 302, and the vehicle body structure 40 is connected with the vehicle door body 10 through the vehicle door lock and the limiting device 30;
when the detector detects the collision pressure on the vehicle door and the collision pressure is lower than the preset pressure threshold, the electromagnetic driving unit 311 and the stopper 301 are kept attracted, the pin of the stopper 301 is separated from the snap-fit structure 302, and the vehicle body structure 40 is connected with the vehicle door body 10 through the vehicle door lock.
It should be noted that the setting of the pressure threshold needs to be obtained according to a plurality of tests, and generally, the requirement of ensuring that the intrusion amount of the vehicle door is small when the pressure is lower than a preset pressure value and ensuring the safety of passengers under the side collision working condition is met; in this application scenario, by setting the pressure threshold, the stopper device 30 is not activated when the safety of the occupant can be ensured, and the stopper device 30 is activated when the safety risk of the occupant is high. This setting realizes the active control to stop device, can avoid the unnecessary damage to stop device 30 and the door body or the automobile body structure that link to each other with it.
In order to reduce the cost, the elastic member 310 may be a spring, and the limiting member 301 may be a stud.
Door connecting device through setting up door lock and stop device in former B post position, strengthens the tie point of automobile body and door, and under the operating mode and/or door closed condition were bumped to the side, through stop device's joint structure, so that door body and automobile body structural connection can resist the side and bump the load to a certain extent, increase the reliability that the door is connected, and then reduce the door invasion volume, improve the security performance by bus.
The vehicle door connecting device with the actual force is particularly suitable for the design of a B-free vehicle body structure. Due to the fact that the B-pillar-free vehicle body structural design is omitted, the B pillar cannot be further strengthened, and the bearing structural design mainly adopts the strengthening design of key points on the vehicle door to improve the side impact structural strength.
The stop device 30 that this embodiment further provided sets up to the cooperation structure of bolt and jack, has simple structure, and practical advantage can break the door of no B post motorcycle type and the limited restriction in automobile body space.
The embodiment further provides multiple implementation manners of the starting device, which may be a mechanical structure of a vehicle door or an electric control device, and the starting device changes the displacement and/or the angle of the limiting member 301 to realize the engagement between the limiting member 301 and the engaging structure 302, where the engaging state may be the engagement when the vehicle door is closed, or the engagement when the vehicle door is impacted by a load under a side impact condition, and may be set according to needs, and the embodiment is not limited.
