[0021] Example: See Figures 1 to 3 A semi-hidden outward opening handle structure for an automobile includes a handle assembly for installation on an automobile door panel, the handle assembly includes a base 1, and the base 1 is provided with a plurality of multi-degree-of-freedom mounting position adjustable locking structures 13, which are used to connect with the door sheet metal to ensure that the connection between the handle assembly and the body sheet metal is more stable and controllable. Among them, the multi-degree-of-freedom mounting position adjustable locking structure 13 is an existing structure and will not be described in detail.
[0022] A mounting hole is provided on the base 1, in which a base decorative cover plate 2 and a handle body 3 are installed. A handle decorative cover plate 14 is also provided on the outside of the handle body 3, and a sealing strip 15 (secondary injection molding) is provided around the handle decorative cover plate 14 to be interference fit with the sheet metal on the outside of the door to ensure the sealing of the outward opening handle and the door panel. After the handle assembly is installed on the door panel of the car, the handle decorative cover plate 14 is flush with the surface of the door panel, realizing a semi-hidden structure of the door handle. Specifically, the base decorative cover plate 2 is concave so that there is a gap between it and the handle body 3, so that the hand can reach into the gap to pull the handle body 3 to complete the unlocking and opening of the door.
[0023] Among them, a first rotating shaft 4 is movably mounted on the inner wall of the base 1, a first reset spring is arranged on the first rotating shaft 4, and a connecting arm is installed on the first rotating shaft 4, and the handle body 3 is connected to the rotating shaft through the connecting arm, so that it can rotate around the first rotating shaft 4 and can be reset under the action of the first reset spring. It also includes a reset stabilization structure, which is arranged on the connecting arm or connected to the connecting arm, and is used to limit the reset speed of the handle body 3. A second rotating shaft 5 is also movably mounted on the inner wall of the base 1, a second reset spring is arranged on the second rotating shaft 5, and a rotating arm 6 is installed on the second rotating shaft 5, one end of the rotating arm 6 is connected to the connecting arm, and the other end is connected to the cable 7 for unlocking the door lock. When the handle body 3 drives the connecting arm to rotate, it can drive the rotating arm 6 to rotate and pull the cable 7 to unlock the door lock.
[0024] Specifically, the connecting arm includes two parallel arranged first connecting arms 8 and a second connecting arm 9, and the first connecting arm 8 is provided with the reset stabilization structure or is connected to the reset stabilization structure, wherein the first connecting arm 8 is an approximately S-shaped structure, one end of which is connected to the handle body 3, the middle part is connected to the first rotating shaft 4, and the other end is provided with the reset stabilization structure. Correspondingly, the reset stabilization structure includes a counterweight block 10 installed at the end of the first connecting arm 8, and when the handle body 3 is reset, the counterweight block 10 is directly above the first rotating shaft 4, so that when the handle body 3 rotates, the counterweight block 10 rotates downward, and when the handle body 3 is released, the handle body 3 is reset under the action of the first reset spring. During the reset process, the counterweight block 10 rotates upward, and the first reset spring needs to overcome the gravity of the counterweight block 10, thereby limiting the reset speed and reset impact force of the handle body 3, providing a buffering effect, and preventing pinching or collision. In addition, the reset stabilization structure can also include a fan-shaped gear 11 installed on one side of the first connecting arm 8, and a resistor 12 fixed on the inner wall of the base 1, the resistor 12 has a resistance gear meshing with the fan-shaped gear 11, and the resistance gear rotates at a set constant speed under the drive of the fan-shaped gear 11, so that the resistance gear further provides reset resistance for the handle body 3, so that it can be stably reset at a slower speed, further reducing its reset impact force and speed, improving its service life, feel and safety, reducing the impact force of the handle body 3 returning to its original position after opening, so that the handle returns slowly and steadily during the return process, and the movement is smooth, thereby improving the texture of the product.
[0025] The second connecting arm 9 is approximately S-shaped, one end of which is connected to the handle body 3, the middle part is connected to the first rotating shaft 4, and the other end is fitted with the end of the rotating arm 6. The rotating arm 6 is L-shaped, the end of one arm is fitted and connected to the end of the second connecting arm 9, the middle part is connected to the second rotating shaft 5, and the end of the other arm is connected to the zipper, wherein the end of the second connecting arm 9 that fits the rotating arm 6 is fitted with a certain arc track surface, which cooperates with the end of the rotating arm 6. During the rotation of the second connecting arm 9, it can ensure that the rotating arm 6 rotates at a uniform speed, so that the movement is smooth, and the pulling stability of the cable 7 is ensured to complete the unlocking of the door. At the same time, lubricating oil is applied to the track surface where the handle body 3 contacts the rotating arm 6 to effectively reduce wear and abnormal noise and improve the flexibility of movement.
[0026] The handle body 3 is a shell structure with a cavity 16 inside. Specifically, a sensor can be added to the cavity 16 of the handle body 3 to activate the electronic control system to achieve keyless unlocking when touched by a hand; and automatically lock the car when a person leaves the car. In addition, a micro switch is also provided on the base 1. When the door is opened, the rotating arm 6 rotates to a certain angle to trigger the micro switch to achieve the slow lowering of the frameless door glass, thereby achieving smooth door opening and unlocking.
[0027] The utility model combines the advantages of a hidden handle and a traditional handle. The handle body adopts a semi-hidden structure. After the handle assembly is installed, the handle body is flush with the surface of the car door panel, which reduces wind resistance and improves fuel economy. It adopts a traditional mechanical unlocking structure with lower cost. When in use, the handle body is pulled to drive the connecting arm to rotate, and then the rotating arm is driven to pull the cable to unlock the door. This mechanical unlocking method is less affected by the environment and has good durability. The reset speed of the handle body is limited and buffered by the reset stabilizing structure, so it is not easy to pinch your hands, and the use feel is better, thereby improving the user experience.
[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the technical solution. Ordinary technicians in this field should understand that those modifications or equivalent replacements of the technical solution of the utility model without departing from the purpose and scope of the technical solution of the utility model should be included in the scope of the claims of the utility model.
