According to a specific embodiment of the present disclosure, a vehicle armrest is provided, which includes an armrest frame, wherein the armrest frame includes a plurality of sections (two or more sections), the sections are sequentially disposed from outside to inside, and a transverse collapsing structure 1 is disposed between at least one adjacent two of the sections, so as to stop a relative movement between the adjacent two of the sections in a transverse direction, and the transverse collapsing structure 1 is configured to break under a preset collision condition. Wherein a plurality of said segments may define an elbow rest to provide comfort to the occupant when riding. Wherein "at least one adjacent two of said segments" is understood to mean: if the handrail framework comprises A, B, C three sections which are sequentially arranged from outside to inside, if a transverse crumple structure 1 is arranged between the section A and the section B, a transverse crumple structure can be arranged between the section B and the section C, or the transverse crumple structure is not arranged.

The armrest for a vehicle provided by the present disclosure may be used as a door armrest, in which case the directional terms "inside and outside" also refer to "inside and outside" with respect to the vehicle itself. Further, it will be understood by those skilled in the art that the armrest for a vehicle provided by the present disclosure may also be used as an armrest portion in an armrest box, i.e., a box cover of the armrest box, in which case, with respect to the main driver's seat, the direction toward the main driver's seat is inward and the direction away from the main driver's seat is outward; whereas for the secondary driver's seat the direction towards the secondary driver's seat is inner and the direction away from the secondary driver's seat is outer, that is to say "inner" with respect to the primary driver's seat is "outer" with respect to the secondary driver's seat, whereby the person skilled in the art will immediately be able to move one of the two means of support connected by the transverse crush structure 1 "relatively" inner "towards" outer "when the transverse crush structure 1 breaks, wherein the terms of orientation" inner "and" outer "mean" inner "and" outer "with respect to the primary driver's seat or the secondary driver's seat, which are different from" inner "and" outer "when used as a door armrest.

Through the technical scheme, in the vehicle armrest provided by the disclosure, when the preset collision condition is not met, the plurality of sections can be kept at the original positions through the corresponding stops of the transverse collapse structures, so that the elbow support part is kept, in this case, the elbow support part can play a role in supporting the elbow of a passenger, the width of the elbow support part can be set as required, and the vehicle armrest is beneficial to improving the riding comfort of a vehicle; when reaching and predetermineeing the collision condition (for example the vehicle takes place the side collision), horizontal collapse structure 1 fracture to remove the backstop effect to corresponding section, the section that loses the backstop moves outwards under passenger's the effect of striking, whole handrail skeleton collapses and deforms, can let out partly impact energy on the one hand, on the other hand can reduce and passenger's interact power between the on the other hand, thereby reduce the injury of vehicle handrail for the vehicle to passenger's in-process that the vehicle side collided, for example the injury of elbow and rib, be favorable to strengthening the security performance of vehicle.

In the specific implementation provided by the present disclosure, any one of two adjacent segments may be provided with a guiding structure 2 to guide one of the inner segments to move towards the outer side, so as to avoid that the skeleton segment losing the stopper causes secondary injury to the passenger.

In the specific implementation manner provided by the present disclosure, any one of the two adjacent sections may be provided with a limiting structure 3, so as to limit the movement of the inner one of the two adjacent sections toward the outside after the transverse crush structure 1 is broken, and avoid the inner end of the outer one from being exposed, thereby causing secondary injury to a passenger.

In the embodiments provided by the present disclosure, the handrail framework can comprise two or three or four or more segments, and in the embodiments shown in fig. 1 and 2, the handrail framework comprises two segments. Fig. 1 shows an unbroken state of the transverse crush structure 1, fig. 2 shows a broken state of the transverse crush structure 1, and fig. 1 and 2 are both schematic transverse cross-sectional views. Referring to fig. 1 and 2, the handrail framework comprises an outer section 4 and an inner section 5, the transverse crush structure 1 is arranged between an inner end 42 of the outer section 4 and an outer end 51 of the inner section 5, and the movement of the inner section 5 towards the outside is stopped by the transverse crush structure 1. Wherein optionally the outer end 41 of the outer section 4 is connected to the door trim panel 8.

In the specific embodiment provided by the present disclosure, the inner end 42 of the outer section 4 and the outer end 51 of the inner section 5 may be connected by overlapping, sleeving, or the like. Alternatively, the inner end 42 of the outer section 4 and the outer end 51 of the inner section 5 are stacked on top of each other, i.e., overlapped, so that they can be relatively displaced in a predetermined direction after the transverse crush structure 1 therebetween is broken. It is possible that in one embodiment provided by the present disclosure, the inner end 52 of the outer section 4 is disposed above the outer end 51 of the inner section 5, and the transverse crush structure 1 extends downward from the inner end 42 of the outer section 4 and is disposed outside the outer end 51 of the inner section 5.

In this case, the guide structure 2 may be disposed outside the lateral crush structure 1 and configured as a wedge structure formed with a guide slope inclined downward in an inside-out direction, and when the lateral crush structure 1 is broken, the inner section 5 moves toward the outside along the guide slope, achieving collapse of the armrest frame. It is possible that the guide structures 2 are provided in plurality and spaced apart from each other in the longitudinal direction to contribute to weight reduction.

Alternatively, the stop structure 3 may be arranged outside the guide structure 2 and extend downwards beyond the guide structure 2. When the inner section 5 moves along the guide ramp towards the outside until the outer end of the inner section 5 contacts the stop 3, further outward movement is limited. In order to avoid stress concentration of the limiting structure 3, the outer end of the inner section 5 may be bent, for example, downward, to increase the contact area with the limiting structure 3.

It is also possible that in another embodiment provided by the present disclosure, the inner end of the outer section 4 is disposed below the outer end of the inner section 5 (such embodiment is not shown), and the lateral crush structure 1 can be disposed inwardly of the inner end 42 of the outer section 4 extending downwardly from the inner end 52 of the inner section 5. In this case, the guide structure 2 may be disposed inside the lateral crush structure 1, and configured as a wedge structure, formed with a guide slope inclined downward in an outside-in direction, and when the lateral crush structure 1 is broken, the inner section 5 moves toward the outside along the guide slope, thereby achieving collapse of the handrail frame. It is possible that the guide structures 2 are provided in plurality and spaced apart from each other in the longitudinal direction to contribute to weight reduction.

Alternatively, the stop structure 3 may be arranged inside the guide structure 2 and extend downwards beyond the guide structure 2. When the inner section 5 moves along the guiding ramp towards the outside until the inner end of the outer section 4 contacts the stop formation 3, further out of line movement is limited. In order to avoid stress concentration of the limiting structure 3, the inner end of the outer section 4 may be bent, for example, downward, to increase the contact area with the limiting structure 3.

Alternatively, a downwardly bent inner end 52 (described later) of the inner section 5 may be used as the stopper structure 3.

In the specific embodiments provided by the present disclosure, the transverse crush structure 1 can be broken in any suitable manner. Alternatively, the transverse crush structure 1 can be broken passively, for example by means of external force impact, in which case the connection between the transverse crush structure 1 and the frame section can be weakened, and at this time the inner end of the limiting structure 3 can abut against the weakened portion to provide support, so that the transverse crush structure 1 can obtain the required strength.

Alternatively, the transverse crush structure may be actively broken, for example by current fusing, and the transverse crush structure 1 may be made of a fusible material such as a resistance wire. In this case, a condition of passive fracture, such as fusion, is required. The condition may be a collision force of a human body hitting the armrest for the vehicle. In order to detect the collision force, the inner end of the innermost section is bent downwards to form a transition part, the lower end of the transition part is abutted with a door trim panel 8, a pressure sensor 6 suitable for being connected with a vehicle controller is arranged on the transition part to detect the collision force, and the preset collision condition is that the collision force is larger than or equal to a preset value. The preset value may be a value, for example, 500N, according to the experimental result. Here, it should be noted that the value of the preset value needs to consider the case of invalid impact, that is, the impact generated by the bumpy road condition of the user or the accidental impact during playing.

In addition, in the specific embodiment provided by the present disclosure, the vehicle armrest further includes a skin 7 covering the armrest skeleton to improve the riding comfort and the aesthetic appearance of the vehicle interior. In which, when a vehicle is involved in a side collision and the transverse crush structure 1 is broken, the relative movement of the two adjacent frame segments results in a reduction in the dimension of the armrest frame in the transverse direction, in which case, since the skin 7 is softer, a wrinkle stack is generated, which can play a certain role in protecting the body of the user.

On the basis of the technical scheme, the disclosure further provides a vehicle door interior trim panel assembly, which comprises a vehicle door interior trim panel 8, wherein the vehicle door interior trim panel assembly comprises the vehicle armrest, and the armrest framework is connected to the vehicle door interior trim panel 8.

While the present disclosure has been described in detail with reference to the drawings, the present disclosure is not limited to the details of the embodiments, and various simple modifications may be made to the technical solution of the present disclosure within the technical scope of the present disclosure, and the technical solution of the present disclosure is protected by the present disclosure.

It should be noted that the various features described in the above embodiments may be combined in any suitable manner without departing from the scope of the invention. In order to avoid unnecessary repetition, various possible combinations will not be separately described in this disclosure.

In addition, any combination of various embodiments of the present disclosure may be made, and the same should be considered as the disclosure of the present disclosure, as long as it does not depart from the spirit of the present disclosure.
