A vehicle door assembly according to an embodiment of the first aspect of the invention is described below with reference to the drawings.
As shown in fig. 1 to 5, a vehicle door assembly according to an embodiment of the present invention includes: the door body 1, the linear driving device 2, the first transmission piece 3 and the second transmission piece 4.
The first side of the door body 1 is suitable for being rotatably connected with a vehicle body; the linear driving device 2 is suitable for being rotatably connected with a vehicle body, and the linear driving device 2 is provided with a driving end 21; the first transmission piece 3 is suitable for being rotatably connected with the vehicle body, the driving end 21 is connected with the first transmission piece 3 through a first connecting assembly, the first transmission piece 3 is connected with the second transmission piece 4 through a second connecting assembly, the second transmission piece 4 is connected with the door body 1 through a third connecting assembly, one of the first connecting assembly, the second connecting assembly and the third connecting assembly is a sliding connecting assembly, and the other three of the first connecting assembly, the second connecting assembly and the third connecting assembly are rotating connecting assemblies; the slide-on-connect assembly includes a first member and a second member slidable relative to the first member and adapted to rotate relative to the first member.
According to the vehicle door assembly provided by the embodiment of the invention, the driving end 21 drives the door body 1 to rotate through the first transmission piece 3 and the second transmission piece 4 so as to realize the opening and closing of the door body 1, and the sliding connection assembly is arranged between the driving end 21 and the door body 1, so that the opening angle of the door body 1 can still be changed after the driving end 21 moves to the maximum driving stroke; the door body 1 after opening takes place to hang down under the effect of self gravity, because the variability of door body 1 opening angle for door body 1 can be in order to adapt to different topography condition through the mode that changes opening angle, prevent to be destroyed or warp because of ground collision extrusion door body 1 and lead to the inner structure of door subassembly, thereby guaranteed the structural integrity and the stability of door subassembly, and door body 1 can adapt to different ground clearance, thereby make the robot can make things convenient for more easily to get into the automobile body along door body 1.
According to the embodiment of the invention, taking the application of the vehicle door assembly to an unmanned platform as an example, the lower end of the door body 1 is installed on a vehicle body, the driving end 21 of the linear driving device 2 is extended to push the first transmission piece 3 to rotate, the first transmission piece 3 drives the second transmission piece 4 to move, and the second transmission piece 4 pushes the door body 1 to realize the downward turnover of the door body 1, so that the door body 1 is opened. After the driving end 21 moves to the maximum driving stroke, the door body 1 continues to drop downward under the action of self gravity, at the moment, the second part slides relative to the first part, and when the second part slides to the maximum sliding stroke or the door body 1 directly contacts the ground, the door body 1 stops rotating.
When the ground clearance of the door body 1 is different, the opening angle of the door body 1 can also change along with the change of the ground clearance due to the existence of the sliding connection assembly. For example, when the unmanned platform travels on a rough off-road surface, under the condition that the ground clearance of the door body 1 is reduced, the door body 1 rotates upwards under the support effect of the ground, the second part slides relative to the first part, and the opening angle of the door body 1 is reduced; when the ground clearance of the door body 1 increases, the door body 1 rotates downward under the action of self gravity, the second component slides relative to the first component, and the opening angle of the door body 1 increases accordingly. Like this, when the topography that unmanned platform located is different, the ground clearance between the door body 1 and the ground also can be different, because sliding connection subassembly's effect, the opening angle of the door body 1 can change according to the change of topography to adapt to different topography, on the one hand, can avoid ground extrusion collision door body 1, on the other hand, the robot need not to stride across the step when getting into unmanned platform alright climb up door body 1, and can get into in the automobile body smoothly along door body 1.
It is understood that the range of the opening angle at which the door body 1 can be opened may be changed by changing the range of the relative slidable movement of the first member and the second member or the range of the driving stroke of the driving end 21.
It should be noted that the above-mentioned "maximum driving stroke" refers to: the maximum length that the linear drive device 2 can extend in the door assembly; the above-mentioned "maximum sliding stroke" means: a maximum travel of the second member slidable relative to the first member in the vehicle door assembly; the above-mentioned "ground clearance" means: the distance of the gap between the door body 1 and the ground.
In some embodiments of the present invention, the linear driving device 2 may be a linear driving motor, an air cylinder, a hydraulic cylinder, etc., and the first transmission member 3 and the second transmission member 4 may be connecting rods, and of course, the first transmission member 3 and the second transmission member 4 may have other structures as long as the above limitations on the first transmission member 3 and the second transmission member 4 are satisfied.
As shown in fig. 1 and 2, according to one embodiment of the present invention, the first portion is a guide groove 51, and the second portion is a guide post 52 engaged with the guide groove 51. Thus, the guide post 52 can slide in the guide groove 51, and the cylindrical guide post 52 is suitable for rotating relative to the guide groove 51, so that the structure is simple and the assembly is convenient. Of course, the present invention is not limited thereto, and the first member and the second member may have other structures as long as the first member is slidable with respect to the first member and the second member is adapted to rotate with respect to the first member.
In one embodiment of the invention, the first transmission member 3 is provided with a guide slot 51, the driving end 21 is provided with a guide post 52, and the guide slot 51 extends in the direction in which the driving end 21 is elongated. Thus, the adjustability of the opening angle of the door body 1 is realized through the relative sliding between the first transmission piece 3 and the driving end 21.
As shown in fig. 1 and 2, in another embodiment of the present invention, a guide groove 51 is provided in one of the first transmission member 3 and the second transmission member 4, and a guide post 52 is provided in the other of the first transmission member 3 and the second transmission member 4. Thus, the adjustability of the opening angle of the door body 1 is realized through the relative sliding between the first transmission piece 3 and the second transmission piece 4.
Specifically, the guide groove 51 may be provided at the top end of the first transmission member 3 and extend along the longitudinal direction of the first transmission member 3, and the guide post 52 may be provided on the second transmission member 4; alternatively, the guide groove 51 is provided on the second transmission member 4 and extends along the longitudinal direction of the second transmission member 4, and the guide post 52 is provided on the tip end of the first transmission member 3.

It should be noted that the guide post 52 and the corresponding parts thereof may be an integral structure or a split structure; the guide groove 51 and the corresponding parts may be an integral structure or a split structure, and the present invention is not limited thereto.
According to one embodiment of the present invention, a first flexible sleeve is sleeved over the guide post 52. Like this, first flexible cover can play the effect of buffering, and at the in-process that door body 1 opened or closed, linear drive device 2 no longer extrudees a body 1, but through first flexible cover of extrusion, and then extrudeing a body 1, ensures that door body 1 can not take place to warp the damage because of excessively extruding the automobile body. For example, the first flexible sleeve may be a rubber sleeve, a nylon sleeve, a latex sleeve, or the like.
According to one embodiment of the invention, the rotating connection assembly comprises a pin shaft and a shaft hole, the pin shaft is rotatably matched in the shaft hole, and a second flexible sleeve is sleeved on the pin shaft. Like this, simple structure is reliable to the flexible cover of second can play the effect of buffering, opens or the in-process of closing at the door body 1, and linear drive device 2 is through extrudeing the flexible cover of second earlier, and then extrudeing door body 1, further ensures that door body 1 can not take place to warp the damage because of excessively extruding the automobile body. For example, the second flexible sleeve may be a rubber sleeve, a nylon sleeve, a latex sleeve, or the like.
In the related art, the driving assembly is usually connected to the door body 1 at a position close to the hinge joint, so that the door body 1 is unevenly stressed, and the problems of untight closing and difficult opening of the door body 1 are caused.
