[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0040] It should be noted that if a directional indication is involved in the embodiment of the present invention, the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.
[0041] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
[0042] It should be noted that in order to isolate the dust layer and airflow from the outside from entering the door through the handle, and to isolate the environment inside the car from the outside, and to improve the NVH level of the whole vehicle, the distance between the base 1 accommodating cavity and the handle is designed to be very small, usually about 0.5-1mm;
[0043] However, due to the existence of manufacturing errors, the gap here is designed to be about 0.5-1mm, which cannot actually guarantee the interference between the handle and the sealing ring 6, and there is a certain slight movement of the upper and lower positions of the handle during extension and retraction, with an amount of movement of about 0.2-0.5mm. Affected by the interference between the two, during the process of extending and retracting the handle, it is easy to produce friction with the accommodating cavity and cause abnormal noise.
[0044] In order to solve the above-mentioned problems, the present invention proposes a hidden outer handle 100, aiming to provide a new handle design with a more compact structure, more convenient operation and effective noise reduction.
[0045] See also Figure 1-2In one embodiment of the present invention, the hidden outer handle 100 includes a base 1, a grip portion 2, a shell 3 and a driving member 4; the base 1 is formed with a accommodating cavity with an open end along the forward direction, the grip portion 2 is movably arranged in the accommodating cavity along the front-back direction, and is extended along the front-back direction, and the grip portion is provided with through holes in the upper and lower directions for passengers to hold; the shell 3 is arranged in the accommodating cavity and is fixedly connected to the front end of the grip portion; the driving member 4 is installed on the base 1 and is connected to the grip portion 2, so as to drive the grip portion 2 and the shell 3 to extend out of or retract into the accommodating cavity; wherein, the side wall surface and the rear side surface of the shell 3 are chamfered.
[0046] It is understandable that the drive member 4 of the present invention adopts a combination of a micro motor and a gear transmission to ensure smooth power output and quick response, effectively reduce the impact during starting and stopping, and further reduce abnormal noise. The efficient energy conversion of the micro motor reduces energy consumption and improves the reliability of the overall system. The design optimization of the gear transmission ensures that the movement trajectory of the grip 2 is accurate during the extension and retraction process, avoiding additional noise caused by transmission errors. The drive member 4 is also equipped with an intelligent sensor to monitor the state of the grip 2 in real time, automatically adjust the extension speed, ensure smooth operation without setbacks, and provide users with a smoother user experience.
[0047] The drive member 4 is also equipped with a buffer device to absorb the impact force at the moment when the grip portion 2 is extended and retracted, further reducing noise. The buffer device is made of high-performance materials, has good elasticity and wear resistance, and ensures that it will not deform during long-term use. In addition, the control circuit of the drive member 4 is equipped with an overload protection function to prevent damage caused by abnormal operation, thereby improving the safety and stability of the system. Through these comprehensive designs, the present invention not only effectively solves the problem of abnormal noise, but also greatly improves the service life and user experience of the outer handle.
[0048] In the technical solution of the present invention, when the door needs to be opened, the driving member 4 drives the gripping portion 2 and the shell 3 to extend out of the accommodating cavity, and the door is opened by holding the gripping portion 2; in addition, by setting a chamfer between the side wall surface and the rear side surface of the shell 3, the overlapping area with the accommodating cavity is reduced during the extension and retraction process of the outer handle shell 3, and the friction area is smaller, which can effectively reduce the abnormal noise caused by interference friction.
[0049] In order to further reduce abnormal noise, in one embodiment of the present invention, the chamfer radius is gradually increased from the side wall of the housing 3 to the rear side. In this way, the gap between the side wall of the housing 3 and the accommodating cavity gradually increases in the rear direction, thereby reducing the contact area and friction during the extension and retraction of the outer handle housing 3, effectively suppressing the generation of abnormal noise, and improving the user experience. In addition, the chamfer design can also optimize the movement trajectory of the handle, ensure smooth operation, and extend the service life. By accurately controlling the chamfer radius, it is ensured that the contact point between the housing 3 and the accommodating cavity is always minimized in different telescopic states, further reducing friction noise. At the same time, this design improves the stability of the handle operation, avoids additional wear caused by movement, and enhances the durability of the overall structure. In one embodiment of the present invention, the hidden outer handle 100 also includes a cover body 5, which is fixedly connected to the front side of the housing 3 and covers the accommodating cavity; by setting the cover plate, it is prevented that the external dust layer and airflow enter the interior of the door through the handle, and the environment inside the car is also separated from the outside, which has a great effect on improving the NVH level of the whole vehicle.
[0050] Furthermore, in one embodiment of the present invention, a buckle 31 is provided on the front side of the shell 3, and a buckle 51 is provided on the rear side of the cover 5. The buckle 51 is buckled with the buckle 31. Such a configuration ensures that the cover 5 fits tightly to the shell 3 to prevent loosening. It should be noted that the present invention does not limit the distribution and number of the buckle 31 and the buckle 51, and can be flexibly designed according to actual needs to achieve the best sealing effect and structural stability. In addition, the buckle 31 can be a groove or a convex structure, forming a firm fitting relationship with the buckle 51, ensuring that the cover 5 is not easy to fall off during the driving of the vehicle, further improving the sealing and safety.
[0051] In one embodiment of the present invention, the hidden outer handle 100 further includes a sealing ring 6, which is arranged in an annular shape and surrounds the inner wall of the accommodating cavity; it is understandable that the sealing ring 6 can be fixed by bonding, snapping 51 or integral molding, etc., to ensure that it maintains good sealing performance in various environments, effectively isolates external noise and dust, and further improves the quietness and cleanliness of the vehicle. The use of the sealing ring 6 significantly improves the environmental quality inside the vehicle and provides passengers with a more comfortable and quiet riding space.
[0052] It is understandable that after the sealing ring 6 is provided, due to the manufacturing accuracy and the movement of the handle during extension and retraction, the outer handle will also produce friction with the sealing ring 6 and cause abnormal noise. By chamfering the side wall surface and the rear side surface of the shell 3, the overlapping area with the sealing ring 6 during the extension and retraction of the handle can also be effectively reduced, thereby reducing the abnormal noise.
[0053] In order to further enhance the sealing effect, the surface of the sealing ring 6 is coated with soft glue. The soft glue coating not only enhances the elasticity and fit of the sealing ring 6, but also effectively absorbs slight vibrations, further reduces noise conduction, and ensures a quieter and more comfortable environment inside the car. The selection of soft glue material takes into account both weather resistance and wear resistance to ensure that it will not age or fall off during long-term use. The thickness and uniformity of the coating are also precisely controlled to maximize its shock absorption and noise reduction effects. Through these detail optimizations, the sealing ring 6 not only improves the NVH performance, but also extends the maintenance cycle and reduces the cost of use. In addition, the soft glue coating can be adjusted according to different climatic conditions to meet the use requirements in various environments.
[0054] The outer surface of the grip 2 is provided with a spark pattern 7. It should be noted that the spark pattern 7 refers to the pattern left on the plastic mold after the electric spark machine is processed, and the surface of the handle is surface treated by injection molding to obtain the spark pattern 7. By changing the surface treatment process of the handle, the surface treatment roughness of the handle is increased, which can greatly reduce the friction noise. The introduction of the spark pattern 7 not only increases the aesthetics of the handle, but also effectively improves the comfort and anti-slip performance of the grip through its unique surface texture.
[0055] Furthermore, the spark pattern 7 is thickened. Compared with the fine spark pattern 7, the coarse spark pattern 7 has a rougher surface, is less likely to produce abnormal noise due to friction, and has a better grip, which effectively improves the user experience. This improvement not only enhances the durability of the handle, but also further meets the user's dual needs for comfort and practicality by providing a better grip experience.
