Abstract
Description
Technical Field
[0001] The utility model relates to the field of commercial vehicles, in particular to the field of automotive hidden door handles, and specifically refers to a new type of four-link structure push-type hidden door handle device. Background Art
[0002] Automotive hidden door handles are widely used in new energy vehicles and traditional fuel vehicles, and have the advantages of beautiful appearance, small wind resistance, reduced fuel consumption, and sufficient sense of technology. From the structural form and the way of realizing door opening, they can be divided into: rotary type, push type, up (down) flip type.
[0003] At present, the push-type handles in application are mainly realized by the straight-push actuator cooperating with the four-link or five-link structure to move the handle.
[0004] For the push-type handle with a straight-push actuator cooperating with a four-link structure, due to the structure of the actuator, the holding force in the Y direction after its deployment is insufficient, and it can be easily pushed back to the retracted state.
[0005] The straight-push actuator requires sufficient movement distance in the X direction, so the length of the entire handle assembly will become very long, occupying more space in the door. Summary of the Utility Model
[0006] The purpose of the utility model is to overcome the above-mentioned disadvantages of the prior art, and provide a new type of four-link structure push-type hidden door handle device that meets the requirements of simple structure, convenient operation, and wide application range.
[0007] In order to achieve the above purpose, the new type of four-link structure push-type hidden door handle device of the utility model is as follows:
[0008] The new type of four-link structure push-type hidden door handle device, its main feature is that the device includes a base, an actuator assembly, a wire harness assembly, a balance structure, a driving arm, an actuator rocker arm, a handle body, and a driven arm. The actuator assembly, the wire harness assembly, the balance structure, the driving arm, and the actuator rocker arm are all installed on the base. The actuator rocker arm is arranged above the actuator assembly. The handle body is installed on the driving arm. The driven arm is connected between the handle body and the balance structure.
[0009] Preferably, the actuator assembly contacts the actuator rocker arm, the actuator rocker arm contacts the driving arm, and the force output by the actuator assembly is amplified after being converted and transmitted through the actuator rocker arm and the driving arm.
[0010] Preferably, the device supplies power to the actuator assembly through a wire harness assembly. When the actuator assembly works, it drives the actuator rocker arm to rotate, which drives the active arm to move. The active arm drives the handle body to move outward in parallel. While the handle body moves outward in parallel, it drives the driven arm to move. When the actuator rocker arm rotates to the deployed position, it triggers the deployed position micro switch installed on the base. After receiving the signal, the device stops supplying power to the handle, and the vehicle door handle is deployed.
[0011] Preferably, the device supplies a reverse voltage to the actuator assembly through the wire harness assembly. The actuator reverses and brings back the actuator rocker arm. The supporting force received by the active arm disappears, and under the action of the spring force, the handle body is pulled back to the closed position.
[0012] With the new four-link structure push-type hidden vehicle door handle device of the present utility model, when the handle is in the deployed position, it can resist a pushing-back force of more than 500 N. The handle will neither retract nor be damaged functionally. At the same time, the overall length of the handle is more than 20 mm shorter than that of the handle using a direct push actuator, and the overall X-direction space is significantly reduced, greatly reducing the volume of the handle assembly. Through the mechanical analysis of the handle assembly deployment process by a professional simulation software, it can be concluded that the ice-breaking force of the handle can reach more than 300 N, far exceeding 120 N of the handle of the direct push actuator.

[0039] In order to more clearly describe the technical content of the present utility model, the following will be further described in conjunction with specific embodiments.
[0040] The novel four-link structure push-type hidden door handle device of the present utility model includes a base 6, an actuator assembly 2, a wiring harness assembly 5, a balancing structure 9, a driving arm 11, an actuator rocker 13, a handle body 1, and a driven arm 8. The actuator assembly 2, the wiring harness assembly 5, the balancing structure 9, the driving arm 11, and the actuator rocker 13 are all installed on the base 6. The actuator rocker 13 is arranged above the actuator assembly 2. The handle body 1 is installed on the driving arm 11. The driven arm 8 is connected between the handle body 1 and the balancing structure 9.
[0041] As a preferred embodiment of the present utility model, the actuator assembly 2 contacts the actuator rocker arm 13, the actuator rocker arm 13 contacts the active arm 11, and the force output by the actuator assembly 2 is amplified after being converted and transmitted through the actuator rocker arm 13 and the active arm 11.
[0042] As a preferred embodiment of the present utility model, the device supplies power to the actuator assembly 2 through the wire harness assembly 5. The actuator assembly 2 operates to drive the actuator rocker arm 13 to rotate and drive the active arm 11 to move. The active arm 11 drives the handle body 1 to move outward in parallel. While the handle body 1 moves outward in parallel, it drives the driven arm 8 to move. When the actuator rocker arm 13 rotates to the deployed position, it triggers the deployed position microswitch installed on the base. After the device receives the signal, it stops supplying power to the handle, and the vehicle door handle deployment is completed.
[0043] As a preferred embodiment of the present utility model, the device supplies reverse voltage to the actuator assembly 2 through the wire harness assembly 5. The actuator reverses to bring back the actuator rocker arm 13, and the supporting force received by the active arm 11 disappears. Under the action of the spring force, the handle body 1 is pulled back to the closed position.
[0044] In the specific embodiment of the present utility model, in order to solve the problems of the prior art, the present utility model applies a rotary actuator to design a push-type hidden door handle. The present utility model discloses a four-link push-type hidden door handle designed by a rotary actuator. The actuator rocker arm 28 moves around an axis parallel to the Y-axis. The direction of the force is changed through the actuator rocker arm 28 and the active arm 26, and then the active arm 26 of the handle is pushed. Then, through the characteristics of the four-link mechanism, the horizontal extension and retraction of the handle are realized.
[0045] To achieve the above object, the push-type handle assembly of the present utility model is as follows:
[0046] Installation structure: The base 6 is the most important component part. The actuator assembly 2, the actuator rocker arm 13, the active arm 11, the balance structure 9, and the wire harness assembly 5 (including the stop position switch and the open position switch) are all installed on the base 6. The handle body 1 is installed on the active arm 11, and the driven arm 8 connects the handle body 1 and the balance structure 9.
[0047] Figure 2 This is the state after the handle installation is completed. The actuator rocker arm 13 is arranged above the actuator assembly 2, and the length is greatly reduced in the X direction.
[0048] From Figure 2 And Figure 3It can be seen that after the force output by the actuator assembly 2 is converted and transmitted through the actuator rocker arm 13 and the driving arm 11, the force value is amplified. The ice-breaking force when the handle is finally unfolded obtained from the force analysis and simulation is 300 N, which is much greater than 120 N of the direct-push type, and the ice-breaking ability is stronger.
[0049] As Figure 4 shown, the double-headed arrow in the figure indicates the movement direction of the actuator, and the other arrow indicates the return thrust F. The actuator rocker arm and the actuator complete structural self-locking to resist the external return thrust.
[0050] The working process is as follows:
[0051] 1. Deployment process: The vehicle ECU supplies power to the actuator assembly 2 through the wire harness assembly 5. The actuator assembly 2 works, driving the actuator rocker arm 13 to rotate and drive the driving arm 11 to move. The driving arm 11 then drives the handle body 1 to move outward in parallel. Due to the special nature of the four-bar linkage movement, the handle body 1 will drive the driven arm 8 to move while moving outward in parallel. When the actuator rocker arm 13 rotates to the deployment position, it will trigger the deployment position microswitch installed on the base. After the ECU receives the signal, it stops supplying power to the handle, and the handle deployment is completed.
[0052] After the handle deployment is completed, the states of the actuator assembly 2 and the actuator rocker arm 13 are as Figure 4 shown. When the handle receives the return thrust F1 as Figure 5 shown, the force will be transmitted to the actuator rocker arm 13, and the direction of the force is the return thrust F as Figure 4 shown. At this time, the return thrust is perpendicular to the movement direction of the actuator, so no matter how large the return thrust is, the actuator cannot be pushed.
[0053] 2. Recycling process: The vehicle ECU supplies a reverse voltage to the actuator assembly 2 through the wire harness assembly 5. The actuator reverses and brings back the actuator rocker arm 13. The supporting force received by the driving arm 11 disappears, and under the action of the spring force, the handle is pulled back to the closed position.

[0058] With the new four-link structure push-type hidden door handle device of the present utility model, when the handle is in the deployed position, it can resist a push-back force of more than 500 N, the handle will neither retract nor be damaged functionally. At the same time, the overall length of the handle is more than 20 mm shorter than that of the handle using a direct push actuator, and the overall X-direction space is significantly reduced, greatly reducing the volume of the handle assembly. Through the mechanical analysis of the handle assembly deployment process by a professional simulation software, it can be concluded that the ice-breaking force of the handle can reach more than 300 N, far exceeding the 120 N of the direct push actuator handle.
