DETAILED DESCRIPTION

[0035] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily appreciate the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the various details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0036] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation.

[0037] Hidden outward-opening handles, also known as concealed handles, are becoming increasingly common as consumption in the automotive market upgrades. OEMs and consumers are paying more and more attention to the appearance and quality of the vehicle. To enhance their competitiveness, major companies are placing higher demands on the uniformity of the gaps in hidden outward-opening handles.

[0038] Currently, the hidden structure of an exterior door handle consists of a handle base, a rotating arm, and a handle. The front end of the rotating arm is pivotally connected to the handle, while the rear end of the rotating arm is pivotally connected to the handle base. Compared to traditional protruding handles, this hidden structure allows the handle to be flush with the door sheet metal surface when the handle is hidden. However, when the handle is hidden, the uniformity of the gap between the handle and the door sheet metal cannot be guaranteed.

[0039] In order to solve the above problems, an embodiment of the present invention provides a hidden outward-opening handle assembly and a vehicle.

[0040] First, refer to Figures 1 to 5The embodiment of the present invention provides a hidden outward-opening handle assembly, comprising a base 1, a rotating arm 2, and a handle. The base 1 is provided with a mounting shaft 3. The rotating arm 2 has a first end 21 and a second end 22. The first end 21 of the rotating arm 2 is rotatably connected to the mounting shaft 3. The second end 22 of the rotating arm 2 is rotatably connected to the handle. A return torsion spring 4 is sleeved on the mounting shaft 3.

[0041] The reset torsion spring 4 has a first torsion spring arm 41 facing away from the rotating arm 2. A torsion spring limiting groove 11 is provided on the base 1. The first torsion spring arm 41 is limited in the torsion spring limiting groove 11. The torsion spring limiting groove 11 is used to limit the first torsion spring arm 41 along the height direction of the base 1. The first end 21 of the rotating arm 2 is fixed with a limiting rib 23. A rotating arm limiting groove 12 is provided on the base 1. The limiting rib 23 is limited in the rotating arm limiting groove 12. The rotating arm limiting groove 12 is used to limit the limiting rib 23 along the height direction of the base 1.

[0042] Specifically, the concealed outward-opening handle assembly provided in the embodiments of the present invention is applied to an automobile. The automobile can be of various types, such as a sedan, commercial vehicle, off-road vehicle, or sport utility vehicle. It should be noted that the description of the embodiments of the present invention regarding the top, bottom, front, and back, inside, and outside directions corresponds to that of an automobile.

[0043] A car includes door sheet metal, with a base 1 mounted on the door sheet metal, specifically located inside the outer surface of the door sheet metal. A handle, also known as a handle, is connected to the base 1. The handle has a hidden state, with a recessed groove defined in the base 1. When the handle is hidden, it resides within the recessed groove. When hidden, the handle does not protrude from the outer surface of the door sheet metal, and a gap exists between the handle's circumference and the door sheet metal. To maintain the vehicle's overall appearance, the gap between the handle's circumference and the door sheet metal must be uniform when the handle is hidden.

[0044] The hidden external opening handle assembly may further include an actuator connected to a push rod, which is connected to the pivot arm 2. The handle also has an ejection state. When the handle is in the ejection state, the handle protrudes from the outer surface of the door sheet metal, making it easier for the user to pull the handle. When the handle is in the hidden state, the actuator can be controlled to operate. The actuator's operation will drive the push rod to be pushed out. Through the cooperation between the push rod and the pivot arm 2, the pivot arm 2 is driven to rotate around the mounting axis 3, so that the second end 22 of the pivot arm 2 can eject the handle, thereby placing the handle in the ejection state. Similarly, when the handle is in the ejection state, the actuator is controlled to reset, and the push rod is also reset. The reset torsion spring 4 is released and reset. The reset force of the reset torsion spring 4 acts on the pivot arm 2, causing the pivot arm 2 to retract and reset, driving the handle to reset, and returning the handle to the hidden state.

[0045] The above mainly describes the operation process of the handle in the hidden external opening handle assembly to illustrate the role played by the rotating arm 2 and the return torsion spring 4, and does not serve as a limitation on the embodiments of the present invention. According to the above process, the rotating arm 2 and the return torsion spring 4 play an important role in the process of hiding and ejecting the handle. If the rotating arm 2 and the return torsion spring 4 shift along the height direction of the base 1 during operation, the uniformity of the circumferential gap between the handle and the door sheet metal cannot be guaranteed when the handle returns from the ejected state to the hidden state. Therefore, in order to ensure the uniformity of the circumferential gap between the handle and the door sheet metal, the embodiments of the present invention limit the rotating arm 2 and the return torsion spring 4 along the height direction of the base 1, avoiding the displacement of the rotating arm 2 and the return torsion spring 4 along the height direction of the base 1.

[0046] The height direction of the base 1 can be referred to Figure 1 The direction indicated by the arrow C in the figure. The car includes a door, and the hidden external opening handle assembly is arranged on the door. When the door is closed, the height direction of the base 1 is consistent with the height direction of the car. It should be noted that the mounting shaft 3 is stationary, and the first end 21 of the rotating arm 2 rotates relative to the mounting shaft 3. Figure 5 The first end portion 21 of the rotating arm 2 is provided with a through mounting hole 24, and the first end portion 21 of the rotating arm 2 is rotatably connected to the mounting shaft 3 through the mounting hole 24. The first end portion 21 and the limiting rib 23 can be integrally formed.

[0047] By matching the limiting rib 23 with the pivot arm limiting groove 12, the pivot arm 2 can be restricted to a smaller range of movement. By matching the limiting rib 23 with the pivot arm limiting groove 11, the first torsion spring arm 41 is precisely positioned on the base 1. During the long-term use of the hidden external opening handle assembly, the pivot arm 2 is prevented from moving up and down along the mounting axis 3 due to factors such as deformation of the reset torsion spring, thereby ultimately achieving a uniform circumferential gap between the handle and the door sheet metal in the hidden external opening handle assembly. It should be noted that during the rotation of the first end 21 of the pivot arm 2, the limiting rib 23 always remains partially constrained within the pivot arm limiting groove 12.

[0048] In the embodiment of the present invention, the pivot arm 2 is more reliably limited by the limiting matching of the first torsion spring arm 41 and the torsion spring limiting groove 11 and the limiting matching of the limiting rib 23 and the pivot arm limiting groove 12, thereby achieving the stability of the position of the handle connected to the pivot arm 2, improving the position of the handle relative to the base 1, and then ensuring the uniformity of the circumferential gap between the handle and the vehicle door sheet metal, thereby solving the problem that the uniformity of the gap between the handle and the vehicle door sheet metal cannot be guaranteed.

[0049] Reference Figure 2 and Figure 4The torsion spring limiting groove 11 has two first mounting guide surfaces 111 and two first limiting surfaces 112. The two first mounting guide surfaces 111 are arranged opposite to each other. The bottoms of the two first mounting guide surfaces 111 are connected by two first limiting surfaces 112. The first torsion spring arm 41 is limited between the two first limiting surfaces 112.

[0050] Specifically, the first mounting guide surface 111 can be an arcuate surface. The space between the two first mounting guide surfaces 111 forms the opening of the torsion spring retaining groove 11. During assembly of the reset torsion spring 4, its first torsion spring arm 41 is assembled into the torsion spring retaining groove 11 along the first mounting guide surface 111 of the torsion spring retaining groove 11. In this embodiment of the present invention, the provision of the first mounting guide surface 111 facilitates the assembly of the first torsion spring arm 41 into the torsion spring retaining groove 11.

[0051] Reference Figure 4 The arm limiting groove 12 has two side walls arranged opposite to each other, and the side walls include a second installation guide surface 121 and a second limiting surface 122 which are smoothly connected. The limiting rib 23 is limited between the two second limiting surfaces 122 .

[0052] Specifically, each sidewall includes a smoothly connected second mounting guide surface 121 and a second limiting surface 122. When the pivot arm 2 is assembled to the base 1, the limiting rib 23 fits into the pivot arm limiting groove 12 along the second mounting guide surface 121. In this embodiment of the present invention, the provision of the second mounting guide surface 121 facilitates the fitting of the limiting rib 23 into the pivot arm limiting groove 12.

[0053] The first torsion spring arm 41 is loosely fitted between the two first limiting surfaces 112, and the limiting rib 23 is loosely fitted between the two second limiting surfaces 122. In this embodiment of the present invention, the loosely fitted limiting rib 23 between the two second limiting surfaces 122 prevents the rotation of the first end portion 21 of the rotating arm 2 from being affected.

[0054] The unilateral clearance between the first torsion spring arm 41 and the first limiting surface 112 is less than or equal to 0.05 mm, and the unilateral clearance between the limiting rib 23 and the second limiting surface 122 is less than or equal to 0.15 mm. In the embodiment of the present invention, the above-mentioned configuration keeps the unilateral clearance between the limiting rib 23 and the second limiting surface 122 within an appropriate range to prevent the rotation of the first end portion 21 of the rotating arm 2 from being affected.

[0055] Reference Figure 4 A support plate 13 is fixed on the base 1 , and a torsion spring limiting groove 11 is provided on the support plate 13 . The torsion spring limiting groove 11 passes through the support plate 13 along the extending direction of the first torsion spring arm 41 .

[0056] Specifically, the torsion spring limiting groove 11 is formed on the support plate 13. In the embodiment of the present invention, the torsion spring limiting groove 11 is provided through the support plate 13 along the extension direction of the first torsion spring arm 41, so that the end of the first torsion spring arm 41 close to the mounting shaft 3 is easily limited in the torsion spring limiting groove 11.

[0057] Reference Figure 2 Two return torsion springs 4 are sleeved on the mounting shaft 3 , the first end 21 of the rotating arm 2 is located between the two return torsion springs 4 , and the return torsion spring 4 also has a second torsion spring arm close to the rotating arm 2 , and the second torsion spring arm is against the rotating arm 2 .

[0058] Specifically, the number of the torsion spring limiting grooves 11 is equal to the number of the reset torsion springs 4, that is, referring to Figure 2 Two torsion spring limiting grooves 11 are correspondingly provided on the base 1. In the embodiment of the present invention, by the arrangement of the second torsion spring arm against the rotating arm 2, the reset force of the reset torsion spring 4 can act on the rotating arm 2, so that the rotating arm 2 can retract and reset.

[0059] Reference Figure 1 and Figure 3 A plurality of accommodating portions 14 are provided on the base 1 , and a tolerance adjuster 5 is provided in each accommodating portion 14 .

[0060] Specifically, the number of accommodating portions 14 can be set according to actual needs, such as 3, 4, or 5. The number of accommodating portions 14 is equal to the number of tolerance adjusters 5. In the embodiment of the present invention, the provision of multiple tolerance adjusters 5 can achieve tolerance compensation during the assembly of the concealed outward-opening handle assembly.

[0061] The base 1 is made of glass fiber reinforced polypropylene with a glass fiber content of 30%, and the rotating arm 2 is made of glass fiber reinforced nylon with a glass fiber content of 30%.

[0062] Specifically, the base 1 is made of PP-GF30, and the rotating arm 2 is made of PA6-GF30. In the embodiment of the present invention, the above configuration makes the base 1 and the rotating arm 2 have high strength and rigidity.

[0063] It can be understood that the above examples are merely examples listed for a better understanding of the technical solutions of the embodiments of the present invention, and are not intended to be the sole limitation on the embodiments of the present invention.
