Embodiment Construction
[0115] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the invention, not to limit the invention.
[0116] In order to achieve this purpose, the present invention provides a gravity self-locking mechanism for handrails and its design method. Under normal driving conditions, the gravity self-locking mechanism for handrails does not work, and only uses gravity to function as a self-locking mechanism during collisions. The opening angle of the armrest to protect the passenger's back from the armrest.
[0117] The present invention first designs the design method of this self-locking mechanism utilizing inertia, and designs two types of handrail self-locking systems according to this method. The invention discloses...

The invention relates to the technical field of automobile seats, in particular to a handrail gravity self-locking mechanism and a design method thereof. The invention provides a handrail gravity self-locking mechanism which comprises a locking piece and a handrail locking shaft. The locking piece is installed on a handrail support through a locking piece rotating shaft; the handrail locking shaftis mounted on the handrail; in a normal state, the locking piece does not make contact with the handrail locking shaft under the action of gravity, the locking piece is located at the unlocking position, and the handrail is freely opened to the maximum angle; in the collision state, the locking piece rotates along the locking piece rotating shaft under the inertia effect, when the set acceleration is exceeded, the locking end of the locking piece and the handrail locking shaft are collided and locked, the locking piece is located at the locking position, and the opening angle of the handrailis limited. Functions and convenience in use of the handrail under normal use conditions are guaranteed, use experience of customers is unaffected, locking in a collision state is guaranteed, safety of passengers is protected, and the mechanism is small in structural space, easy to arrange, low in price and low in cost.
Description
technical field [0001] The invention relates to the technical field of car seats, and more specifically, to an armrest gravity self-locking mechanism and a design method thereof. Background technique [0002] There are generally three seats in the rear seat of a car, and the middle seat is generally narrower than the two sides. An armrest will be placed on the middle seat. When no one is sitting in the middle seat, passengers on both sides can let go or place other items such as water glasses. When the armrests are closed, the middle seat can still sit. [0003] At present, some armrests will be equipped with special complex locking mechanisms, but the armrests are generally complex in structure and heavy in weight, such as the rear central armrest of Volkswagen Huiang and the rear central armrest of Audi A6L. [0004] Figure 1a A schematic diagram of a handrail with a complex locking mechanism of the prior art is revealed, such as Figure 1a As shown in the armrest, when ...
