Description
Technical Field
[0001] The utility model relates to the technical field of automobile door handle accessories, in particular to a rotary handle mechanism. Background Art
[0002] Existing car doors are unlocked by rotating a handle, and the handle is generally movably arranged on a shell, such as Chinese Patent No. ZL202121343613.7, which is a mechanical swing-out handle with a PUSH mechanism, including: a handle base, which is installed in the vehicle body; a handle body, which is installed in the handle base and has at least an initial position state, a drive position state, a pre-deployed position state, and an unlocked position state; a transmission arm, which is transmission-connected to the handle body; a PUSH switch, which is transmission-connected to the transmission arm; an unlocking block, which is transmission-connected to the handle body and is connected to the door lock control. Pressing the handle body switches the handle body from the initial position state to the drive position state, and activating the PUSH switch at the same time. After the PUSH switch is activated, the handle body switches from the drive position state to the pre-deployed position state, and pulling the handle outward
[0003] The hand body switches it from the pre-deployed position to the unlocked position. The handle adopts a purely mechanical structure, does not require electric start, has low manufacturing cost, is more reliable in use, and has no noise when the handle is opened. However, there is no structure to block the unlocking at the unlocking movement position of the unlocking block. If the car door collides, it may easily cause the handle to rotate to unlock. At this time, when the door is unlocked, the person in the car is easily thrown out of the car. Therefore, the safety performance needs to be further improved. Utility Model Content
[0004] The utility model aims to provide a rotary handle mechanism, in which an elastically movable inertial rod is provided in the unlocking movement direction of a pendulum block assembly. When a vehicle collides, the inertial rod elastically pops out to hinder the unlocking movement of the pendulum block assembly. The door cannot be unlocked and opened after a vehicle collision, thereby achieving the function of protecting people from being thrown out of the car.
[0005] The purpose of the utility model is achieved in this way:
[0006] A rotary handle mechanism comprises a pendulum assembly and an inertia rod movably arranged on a housing, and a handle for driving the pendulum assembly to move; the pendulum assembly, the handle and the inertia rod are elastically movably arranged on the housing, the pendulum assembly has a locked state and an unlocked active state on the housing, the handle has an initial state, a pop-up state and an unlocked state on the housing, and the inertia rod has a pending state and a triggered state on the housing;
[0007] The pendulum assembly is in a locked state, and at least part of the pendulum assembly acts on the limiting portion of the housing; the handle moves and drives the pendulum assembly to move, and the pendulum assembly is in an unlocked active state. In addition, the pendulum assembly and the handle are both elastically reset on the housing;
[0008] When the inertia rod is in a pending state, when the handle swing block assembly moves, the inertia rod does not act on the swing block assembly;
[0009] When the inertia rod is in a triggered state and the handle pendulum block assembly moves, the inertia rod acts on the pendulum block assembly to hinder the movement of the pendulum block assembly.
[0010] The inertia rod is swingably arranged on the housing, a first spring is arranged on the swing connection between the housing and the inertia rod, and a positioning part is arranged on the housing;
[0011] When the inertia rod is in a pending state, one end of the first spring abuts against the positioning portion, and the other end of the first spring abuts against the inertia rod, so that the inertia rod is elastically positioned on the shell by the first spring in the pending state; the movement and resetting of the inertia rod are realized by the control limit at both ends of the first spring.
[0012] When the vehicle is hit, the inertia rod is triggered by the collision force, the first spring is compressed by the collision force, and the inertia rod moves faster than the handle pushing the pendulum assembly to prevent the pendulum assembly from continuing to move to unlock the door, thereby realizing the handle's inertia resistance function.
[0013] After the collision force disappears, the third spring, the second spring and the first spring all reset elastically to reset the handle to the initial state, the pendulum assembly resets to the locked state, and the inertia rod resets to the pending state, thereby realizing the reset function.
[0014] The handle is rotatably connected to the shell, the handle is arranged on the outer side of the shell, the pendulum block assembly is swingably arranged on the inner side of the shell, and the handle is provided with an acting part that is limited and movable on the inner side of the shell; when the pendulum block assembly switches from a locked state to an unlocked active state, the acting part acts on the pendulum block assembly as the handle rotates to drive the pendulum block assembly to move, thereby realizing the unlocking function.
[0015] The pendulum block assembly includes a pendulum arm swingably arranged on the inner side of the shell, and a second spring arranged on the swing arm; when the pendulum block assembly is in a locked state, one end of the second spring abuts against the swing arm, and the other end of the second spring abuts against the limiting portion of the shell. When the pendulum block assembly is in a locked state, it is elastically locked to the shell by the second spring, and the swing arm is controlled to move on the base through an elastic connection.
[0016] The shell is provided with an installation slot corresponding to the swinging cooperation position of the swing arm, and the swing arm is provided with an anti-slip block matching the shape of the installation slot; when the shell and the swing arm are installed, the anti-slip block is aligned with the installation slot and installed on the shell, and by rotating the swing arm, the anti-slip block forms a staggered snap connection with the installation slot as the swing arm swings, thereby preventing the swing arm from detaching from the shell outwards; when the swing arm swings, due to the staggered snap connection formed between the anti-slip block and the installation slot, a stopper is provided on the shell, and the swing arm swings and rotates on the shell in a positioned manner and cannot detach from the shell outwards.
[0017] An arc-shaped limit slot is provided on the shell, and a buckling slot acting on the limit slot is provided on the swing arm; the buckling slot moves relatively to the limit slot with the movement of the swing block assembly to control the movement stroke of the swing block assembly.
[0018] The handle is rotatably arranged on the outside of the shell, and a third spring is provided at the rotational connection between the shell and the handle. The handle is elastically rotated on the shell through the third spring to realize the initial, pop-up and unlocked states of the handle on the shell. When the user rotates the handle, the handle drives the swing arm to move in the unlocking direction. When the user releases the handle, the handle is elastically reset by the third spring.
[0019] A stepless or stepped rotational fitting portion is provided at the rotational connection between the housing and the handle, and the handle is rotated steplessly or stepwise on the housing through the rotational fitting portion. The handle is positioned and rotated on the housing through the rotational fitting portion, and the stepped rotational fitting portion enables the handle to be rotated step by step on the housing, so that the user has a good hand feeling when rotating the control handle.
[0020] A slot for connecting the door lock body cable is provided on the swing arm of the swing block assembly. When the swing block assembly is switched from a locked state to an unlocked active state through the handle, the slot pulls the door lock body cable to move with the swing block assembly. The slot pulls the door lock body cable to the corresponding position and unlocks the door.
[0021] An electric lifting glass is provided on the door body, and a micro switch is provided in the direction of movement of the pendulum block assembly. The micro switch is electrically connected to the electric driver that drives the lifting glass. The handle drives the pendulum block assembly to move to the position acting on the micro switch to trigger the electric driver to drive the lifting glass.
[0022] The micro switch is electrically connected to the electric driver that drives the lifting glass. The handle drives the pendulum block assembly to move to the position acting on the micro switch to trigger the electric driver to drive the lifting glass. The utility model is a manually screwed-out handle. The handle is pressed on the end of the handle to pop out. The handle is pulled to make the handle touch the micro switch, triggering a short drop of the door glass. Continuing to pull the handle triggers the door to be unlocked. When the vehicle collides, the inertia rod pops up to prevent the handle from driving the swing arm to continue moving. The swing arm cannot move to the position to unlock and open the door, thereby protecting people from being thrown out of the door.
[0023] The beneficial effects of the utility model are as follows:
[0024] By providing an elastically movable inertial rod in the unlocking movement direction of the pendulum block assembly, when the vehicle collides, the inertial rod elastically pops out to hinder the unlocking movement of the pendulum block assembly. The door cannot be unlocked after the vehicle collides, thereby protecting people from being thrown out of the car and improving safety performance. BRIEF DESCRIPTION OF THE DRAWINGS
