A head-impact anti-detachment structure for handrail assembly

Abstract

This utility model provides a head-impact anti-detachment structure for an armrest assembly. The rear air vent covering panel can move along the extension direction of the protrusion. Under normal conditions, the hook is connected to the side of the protrusion near the bottom. After impact, the hook is connected to the side of the protrusion near the top, and at this time, the hook and the T-shaped structure restrict each other, making it impossible for the hook and the protrusion to detach. Consequently, the rear air vent covering panel cannot detach from the armrest frame, and the protrusion stops moving due to the restriction of the hook, making it impossible for the rear air vent covering panel and the armrest frame to detach. The rear air vent covering panel and the protrusion are integrally formed, which does not affect the aesthetic appearance. The structure is compact, occupies little space, and can effectively solve the problem of rear air vent assembly detachment.

Description

Technical Field

[0001] This utility model belongs to the field of automotive interior technology, and in particular relates to a head-impact prevention and anti-detachment structure for armrest assembly. Background Technology

[0002] Traffic accidents primarily involve side-impact and frontal collisions. In terms of injury locations, the head, chest, shoulders, hips, and lower limbs are most vulnerable. While injuries to the chest, shoulders, lower limbs, and hips generally do not directly cause death, head injuries can directly lead to pedestrian fatalities. Therefore, research on head injuries is of paramount importance in automotive crash studies. In China, because many rear-seat passengers are not accustomed to wearing seatbelts, in a frontal collision, their heads may strike the passenger side dashboard. If the dashboard structure does not provide adequate energy absorption, the occupant's head can experience significant deceleration in a short period, resulting in injury. Therefore, research on head injuries caused by the passenger side dashboard is extremely crucial.

[0003] In recent years, with the development of the automotive industry, consumers have paid increasing attention to passenger safety. Because protrusions inside passenger vehicles can cause significant injury to occupants during a collision, the government has revised relevant regulations. For newly certified models, the standard "GB11552-2009 Passenger Vehicle Interior Protrusions" came into effect on January 1, 2012; for models already in production, the standard came into effect on January 1, 2013.

[0004] When a head impacts the rear area of ​​the sub-dashboard, the impact force is approximately downward in the Z-axis direction. The impact force is transmitted from top to bottom through the armrest, armrest bracket, sub-dashboard bracket, and finally to the floor beam bracket. To minimize head injury, there should be no debris splashing from the rear of the sub-dashboard, and the product should not detach (as sharp structures on the back would be exposed) to cause head injury to occupants. Therefore, this invention proposes an anti-detachment structure for the armrest assembly to address these issues. Utility Model Content

[0005] This utility model provides a head-bump prevention structure for handrail assembly, which aims to solve the problems mentioned in the background art.

[0006] This utility model is implemented as follows: a head-bump anti-detachment structure for an armrest assembly, including a rear air vent covering panel and an armrest frame;

[0007] The rear air vent covering panel and the armrest frame are connected by a snap-fit ​​connection. The rear air vent covering panel has a protrusion with a T-shaped structure. The armrest frame is slidably connected to the protrusion. The armrest frame has a hook located below the top of the protrusion.

[0008] Preferably, the rear air vent covering panel can move along the extension direction of the boss.

[0009] Preferably, when the top of the boss touches the hook, the rear air vent covering panel cannot detach from the armrest frame.

[0010] Preferably, the rear air vent covering panel and the boss are integrally formed.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The rear vent trim panel can move along the extension direction of the boss. Under normal conditions, the hooks are connected to the side of the boss near the bottom (see appendix). Figure 4 After being impacted, the hook connects to the side of the boss near the top (see appendix). Figure 5 Furthermore, at this point, the hook and the T-shaped structure restrict each other, preventing the hook and the boss from detaching; consequently, the rear air vent trim panel cannot detach from the armrest frame, and the boss stops moving due to the restriction of the hook, thus preventing the rear air vent trim panel and the armrest frame from detaching; the rear air vent trim panel and the boss are integrally formed, which does not affect the aesthetic appearance, has a compact structure, occupies little space, and can effectively solve the problem of the rear air vent assembly falling off.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0021] The components of the present invention embodiments described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0023] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a head-collision anti-detachment structure for an armrest assembly, including a rear air vent covering panel 1 and an armrest frame 2; the rear air vent covering panel 1 and the armrest frame 2 are connected by a snap-fit ​​connection, the rear air vent covering panel 1 has a protrusion with a T-shaped structure, the armrest frame 2 is slidably connected to the protrusion, and the armrest frame 2 has a hook 3 located below the top of the protrusion.

Under normal conditions, the hook 3 is connected to the side of the boss near the bottom (see appendix). Figure 4 After being impacted, the hook 3 connects to the side of the boss near the top (see appendix). Figure 5 Furthermore, at this time, the hook 3 and the T-shaped structure restrict each other, making it impossible for the hook 3 and the boss to detach; consequently, the rear air vent covering panel 1 cannot detach from the armrest frame 2, and the boss stops moving due to the restriction of the hook 3, making it impossible for the rear air vent covering panel 1 and the armrest frame 2 to detach.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
