Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 to 10, a two-stage type automobile door handle includes:
the handle base 1 is fixed in the vehicle body;
the handle main body 2 is hidden in the handle base 1 and is flush with the vehicle body, the handle main body 2 is rotatably connected with the handle base 1, and the handle main body 2 has an initial hidden state, a pre-unfolding state and at least 3 free positions of complete unfolding;
the door lock comprises a swing arm 3 and an unlocking block 4, wherein the swing arm 3 is in contact connection with the unlocking block 4, and a pull wire (not shown in the drawing) for unlocking the door lock of the vehicle door is connected to the unlocking block 4;
the actuator 5 is in communication connection with an automobile running computer and is used for pushing the swing arm 3 and pushing the handle main body 2 from an initial hidden state to a pre-unfolding state;
the handle main body 2 and the swing arm 3 are rotatably connected with the handle base 1 through the same transmission shaft 6, and the handle main body 2 and the swing arm 3 are in transmission connection through the transmission shaft 6.
In this embodiment, a through hole 7 is formed in the handle base 1, a first rotating hole 8 is formed in the swing arm 3, a second rotating hole 9 is formed in the handle body 2, one end of the transmission shaft 6 is inserted into the first rotating hole 8, and the other end of the transmission shaft 6 penetrates through the through hole 7 and then is inserted into the second rotating hole 9; the protruding transmission rack 10 that is equipped with of lateral wall of transmission shaft 6, first commentaries on classics hole 8 and second change hole 9 and have all seted up drive groove 11, transmission rack 10 card go into extremely drive groove 11 in. The embodiment provides a specific structure of the transmission shaft 6, so that the handle main body 2 and the swing arm 3 are rotatably connected with the handle base 1, and the handle main body 2 and the swing arm 3 can be in transmission connection.
Preferably, the transmission racks 10 are four in number and are uniformly distributed on the periphery of the transmission shaft 6 at intervals of 90 degrees. By adopting the setting of the transmission rack 10 in the optimal structure, the whole transmission shaft 6 is in a cross shape, the stress of each part is more uniform when the swing arm 3 and the handle main body 2 are transmitted, the situation of blocking or slipping can not occur, and the handle main body 2 is ensured to be smoothly opened or closed.
In the process of switching the handle body 2 from the initial concealed state to the pre-deployed state, the door lock of the automobile needs to be always kept in the locked state, and in the process of switching from the pre-deployed state to the fully deployed state, the door lock of the automobile needs to be switched from the locked state to the unlocked state. In order to realize the above-mentioned actions and functions, in this embodiment, an abutting portion 12 is disposed at one end of the swing arm 3 close to the unlocking block 4, a transmission hook portion 13 is disposed on the unlocking block 4, the abutting portion 12 is contactably connected with the transmission hook portion 13, and a section of idle stroke 14 exists between the abutting portion 12 and the transmission hook portion 13. The in-process that handle main part 2 switched to the state of unfolding in advance from initial hidden state, butt portion 12 moves and does not collude portion 13 contact with the transmission in idle stroke 14, and when handle main part 2 from the state of unfolding in advance to the in-process of state of unfolding completely, butt portion 12 colludes portion 13 contact with the transmission and drives unlocking block 4 and rotate together to drive door lock through acting as go-between and realize the unblock.
Because the output shaft of executor 5 is generally less and mostly cylindric, consequently less with the contact surface of swing arm 3, the general transmission efficiency of stability is lower, and driven effect is also relatively poor. Preferably, a pushing block 15 is connected to an output shaft of the actuator 5, a pushing groove 16 is formed in one end, close to the actuator 5, of the swing arm 3, and the pushing block 15 can be inserted into the pushing groove 16 and pushes the swing arm 3 to rotate. Through the cooperation of ejector pad 15 and push away groove 16, increase area of contact to promoted transmission efficiency and stability greatly, made the walking of swing arm 3 put forward more accurately, ensured holistic normal work operation.
In this embodiment, the unlocking block 4 is rotatably connected to the handle base 1 through a rotating shaft 17. Adopt the structure of this embodiment for unlocking piece 4 realizes the unblock through the pivoted mode and the position when locking switches, compares in modes such as translation, and structural simple reasonable more, stability is better, and the installation space who just occupies is littleer.
In this embodiment, the transmission shaft 6 is sleeved with a first reset torsion spring 18, and the rotating shaft 17 is sleeved with a second reset torsion spring 19. With the structure of the present embodiment, after the door is opened to release the handle main body 2, the swing arm 3, and the unlocking piece 4 can all return to the initial position by the action of the restoring forces of the first and second restoring torsion springs 18 and 19.
The utility model provides a pair of two-section type automobile door handle has three kinds of states at least, is respectively: an initial hidden state, that is, a state when the handle main body 2 is closed, which is integrated with the vehicle body in appearance; the pre-unfolding state is a state when the actuator 5 is started by an instruction and pushes the swing arm 3 to rotate once, so that the handle main body 2 is lifted and popped up; the complete expansion state, the state of unfolding in advance promptly, the passenger grabs the handle main part 2 of the state of unfolding in advance promptly to power pulling handle main part 2 rotates to the state of unfolding in advance by a wide margin, thereby drives swing arm 3 and takes place the secondary rotation, and the butt portion 12 of swing arm 3 and the transmission of unblock block 4 collude the portion 13 contact and transmission this moment, realizes the function of unblock door through acting as go-between.
When the vehicle door is opened, an instruction is sent to start the actuator 5, the actuator 5 pushes the swing arm 3 to rotate for a first period through the push block 15, the swing arm 3 enables the handle main body 2 to rotate from an initial hidden state to a pre-unfolding state through the transmission shaft 6, the abutting part 12 on the swing arm 6 moves in an idle stroke 14 in the process, and the unlocking block 4 changes, so that the vehicle door is still in a locking state; then, the handle body 2 in the pre-unfolding state is held by a hand, the handle body 2 is forcibly turned outwards to the fully unfolding state, and the swing arm 3 is driven to rotate for the second period, in the process, the abutting part 12 of the swing arm 3 is in contact with and drives the transmission hook part 13 of the unlocking block 4, and the transmission hook part 13 rotates and realizes the function of unlocking the vehicle door through wire drawing.
After the vehicle door is opened and the handle main body 2 is loosened, the actuator 5 automatically returns after completing the previous command, the swing arm 3 and the unlocking block 4 both return to the initial position under the restoring force action of the first restoring torsion spring 18 and the second restoring torsion spring 19, and the handle main body 2 returns to the initial hidden state again.
