Abstract

Apparatus, methods and vehicles for door assembles for vehicles are disclosed. A door assembly of a vehicle includes a damping assembly comprising a damping component arranged on a shut face panel of a vehicle door, and a latch assembly arranged on the shut face panel of the vehicle door, where the damping assembly is configured to transition from an initial state to a shock absorbing state as the vehicle closes the vehicle door against a vehicle body before the latch assembly latches the vehicle door to the vehicle body.

First claim

What is claimed is:

1. A door assembly of a vehicle comprising:
a damping assembly comprising a damping component arranged on a shut face panel of a vehicle door; and
a latch assembly arranged on the shut face panel of the vehicle door;
wherein the damping assembly is configured to absorb a shock as the damping assembly transitions from an initial state to a shock absorbing state while the vehicle door closes against a vehicle body before the latch assembly latches the vehicle door to the vehicle body;
wherein the damping component comprises a head component that extends outwardly from the shut face panel a pre-selected length and configured to be received by a jacket component in the shock absorbing state, the jacket component extending outwardly from an outer panel of the vehicle body facing the shut face panel with the vehicle door in a closed configuration such that the head component and the jacket component engage before the latch assembly latches the vehicle door to the vehicle body, wherein the head component and the jacket component are each placed within a casing, and wherein the casing of the head component surrounds at least a portion of the head component.

2. The door assembly of claim 1 , wherein the damping assembly is in the shock absorbing state when the head component is in contact with a first end of the jacket component.

3. The door assembly of claim 1 , wherein the damping assembly is in the initial state when the head component is at a pre-determined distance from a first end of the jacket component.

4. The door assembly of claim 1 , wherein the pre-selected length of the head component prevents the latch assembly from latching the vehicle door to the vehicle body before the damping assembly is in the shock absorbing state.

5. The door assembly of claim 2 , wherein the head component contacts the first end of the jacket component at a pre-determined angle.

6. The door assembly of claim 1 , further comprising:
a movable support attached to the jacket component that allows the jacket component to move in a horizontal direction from an interior portion of the vehicle body to an exterior portion of the vehicle body.

7. The door assembly of claim 1 , wherein the jacket component has a resistance member placed at a first end of the jacket component.

8. The door assembly of claim 7 , wherein shock is absorbed by the head component as the head component pushes the resistance member into the jacket component at the first end of the jacket component, and towards a second end of the jacket component.

9. A method of absorbing the shock while closing the vehicle door against the vehicle body with the door assembly of claim 1 comprising:
closing the vehicle door towards the vehicle body with the damping assembly in the initial state;
transitioning the damping assembly from the initial state to the shock absorbing state as the vehicle door closes; and
absorbing the shock with the damping assembly in the shock absorbing state;
wherein the shock is absorbed while the vehicle door is being closed against the vehicle body, and before the latch assembly latches the vehicle door to the vehicle body.

10. The method of claim 9 , wherein the head component having the pre-selected length is received by a first end of the jacket component at a pre-determined angle.

11. The method of claim 9 , further comprising:
regulating a pressure within the jacket component using an actuation valve, wherein a regulation of pressure assists in absorbing the shock.

12. A vehicle with a door assembly comprising:
a vehicle body; and
at least one vehicle door, wherein the door assembly comprises:
a damping assembly comprising a damping component arranged on a shut face panel of the vehicle door; and
a latch assembly arranged on the shut face panel of the vehicle door;
wherein the damping assembly is configured to absorb a shock as the damping assembly transitions from an initial state to a shock absorbing state while the vehicle door closes against the vehicle body before the latch assembly latches the vehicle door to the vehicle body;

wherein the damping component comprises a head component that extends outwardly from the shut face panel a pre-selected length and configured to be received by a jacket component in the shock absorbing state, the jacket component extending outwardly from an outer panel of the vehicle body facing the shut face panel with the vehicle door in a closed configuration such that the head component and the jacket component engage before the latch assembly latches the vehicle door to the vehicle body, and wherein the door assembly further comprises an actuation valve to regulate a pressure within the jacket component.

13. The vehicle of claim 12 , wherein the damping assembly is in the shock absorbing state when the head component is in contact with a first end of the jacket component.

14. The vehicle of claim 12 , wherein the damping assembly is in the initial state when the head component is at a pre-determined distance from a first end of the jacket component.
