[0041] like Figure 1-5 As shown, the following embodiments disclose a flip-up handle installation and locking structure.

[0042] Specific reference Figure 1 As shown, it at least includes a handle 100, a handle seat 200 and a base 300 fixed to the door sheet metal; the base 300 is provided with a mounting groove matching the shape of the handle seat 200, the handle seat 200 is bowl-shaped, the handle 100 is embedded in the groove, and the first end is hinged to the handle seat 200;

[0043] The back of the handle base 200 is provided with a fixing portion 210 for assembly with the base 300 , and the fixing portion 210 and the base 300 are fixed at the back of the base 300 by a fastener 400 .

[0044] The above is the basic solution of this embodiment.

[0045] A recess is provided on the base 300 to form a mounting groove, and the handle base 200 is embedded in the mounting groove and fixed by a fastener 400 between the fixing portion 210 and the base 300; the upper end of the handle 100 is hinged to the handle base 200, and the lower end can be pulled out of the handle base 200 by hand;

[0046] In addition, in order to facilitate human hand insertion for operation, in this embodiment, a groove is provided at the lower end of the handle 100. At the same time, when the handle 100 is located in the handle seat 200, the lower part of the handle seat 200 still has space for human hand insertion.

[0047] Preferably, in order to ensure the balance of fixation, in this embodiment, two fixing parts 210 are provided and arranged symmetrically.

[0048] Preferably, the fastener 400 in this embodiment may be a screw.

[0049] During assembly, the handle 100 is first hinged to the handle base 200, and then the fixing portion 210 on the handle base 200 is positioned at the installation position of the base 300, and the fastener 400 is screwed into the fixing portion 210 from the back of the base 300 to fix the base 300 and the handle base 200, and then the base 300 is fixed to the inner sheet metal of the vehicle door.

[0050] Compared with the snap-fit ​​connection, the fastener 400 used in this embodiment is easy to operate, occupies less space, and has a stable and reliable connection.

[0051] The specific implementation of the fixing part 210 in this embodiment is as follows: the fixing part 210 is a convex column convexly provided on the back of the handle base 200, and a fixing hole 211 is provided on the convex column;

[0052] The base 300 is provided with a guide groove matched with the boss, and the bottom of the guide groove is provided with a fastener 400 hole 301;

[0053] The fastener 400 extends from the fastener 400 hole 301 on the back of the base 300 into the fixing hole 211 , and the handle base 200 is screwed onto the base 300 .

[0054] Reference Figure 2 As shown, since the handle 100 is located in the groove of the handle base 200 in the storage state, in order to avoid interference between the handle 100 and the fixing part 210, in this embodiment, the fixing part 210 is set on the back of the handle base 200. In order to ensure that the fastener 400 can be threadedly connected with the fixing part 210 as much as possible to make the connection structure more problematic, in this embodiment, the fixing part 210 is set as a boss, and the fixing hole 211 extends from the end face of the boss to the inside.

[0055] Therefore, in order to match with the protruding column, in this embodiment, a connecting column 310 is protrudingly provided on the back of the base 300 , and the guiding groove and the fastener 400 hole 301 are arranged on the connecting column 310 .

[0056] Preferably, in this embodiment, the inner diameter of the guide groove is consistent with the diameter of the protruding column.

[0057] When assembling the handle base 200 , the boss is inserted into the guide groove to achieve positioning between the handle base 200 and the base 300 .

[0058] The advantage of using guide grooves for positioning is that the depth of the guide grooves can be matched with the length of the boss to ensure the connection stability between the handle seat 200 and the base 300. At the same time, compared with the snap fasteners, it is more convenient to set up guide grooves, which can be directly molded onto the base 300 during the injection molding process without adding additional production processes. Moreover, the boss is oriented toward the inside of the door sheet metal, which has a larger setting space.

[0059] In the molding of a conventional automobile door handle 100 , a plastic product is usually used. Therefore, when the fastener 400 is threadedly connected, the fixing hole 211 on the handle base 200 is easily worn. Therefore, in this embodiment, a fastening nut 500 is embedded in the fixing hole 211 .

[0060] The outer peripheral surface of the fastening nut 500 is a smooth surface, and it is pressed into the fixing hole 211 by manual pressing or hot stamping, so that it is embedded in the fixing hole 211;

[0061] When the fastener 400 is connected to the fixing portion 210 , it is threadedly connected to the threads inside the fastening nut 500 , thereby completing the connection with the fixing portion 210 .

[0062] In this embodiment, the diameter of the fastener 400 hole 301 at the bottom of the guide groove is not smaller than the screw hole of the fastening nut 500 , but is also not larger than the diameter of the fastener 400 head of the fastener 400 .

[0063] When the fastener 400 extends from the fastener 400 hole 301 into the fastening nut 500 and is threadedly tightened with the fixing portion 210 , the bottom of the guide groove on the base 300 is clamped between the head of the fastener 400 and the fixing portion 210 .

[0064] Preferably, in order to cooperate with the fastening nut 500, the fixing hole 211 is configured as a stepped hole in this embodiment.

[0065] Specific reference Figure 3 As shown, the fastening nut 500 is axially provided with a main body 510 and a shoulder 520, and the outer diameter of the shoulder 520 is larger than the outer diameter of the main body 510; when the fastening nut 500 is pressed into the fixing hole 211, the shoulder 520 is partially located on the step surface, thereby preventing the fastening nut 500 from being pressed too deep and making it impossible to perform a threaded connection.

[0066] In this embodiment, in order to further ensure the positioning between the handle seat 200 and the base 300, a buckle portion 220 is provided on the back of the handle seat 200, and a buckle hole 302 capable of accommodating the buckle portion 220 passing through is provided on the base 300.

[0067] Specific reference Figure 4 As shown, a hook portion is provided at the end of the buckle portion 220, and the hook portion passes through the buckle hole 302 and hooks the upper edge of the buckle hole 302, so that the hook portion is located at the rear side of the upper edge;

[0068] With such arrangement, when the handle base 200 is separated from the base 300 in the horizontal direction, the hook portion will hook the upper edge of the buckle hole 302 and the separation cannot be completed.

[0069] In this embodiment, the connection mode of the handle 100 and the handle base 200 is configured as follows: a hollow portion is provided on the base 300, and the curved arm 110 and the connecting arm 240 both extend from the hollow portion to the outside of the base 300.

[0070] Specifically, refer to Figure 5 As shown, since the handle 100 is an upward-flipping structure, the bent arm 110 is arranged at the upper end of the main body 510 of the handle 100, and the upper end of the handle seat 200 is provided with an avoidance hole that can accommodate the bent arm 110 to extend and rotate; after the bent arm 110 extends out of the avoidance hole, its end is hinged to the connecting arm 240 through the rotating shaft 600.

[0071] In order to enable the curved arm 110 and the connecting arm 240 to extend from the base 300 , a hollow portion is provided on the base 300 , and the curved arm 110 and the connecting arm 240 extend from the hollow portion to the outside of the base 300 .

[0072] Preferably, in this embodiment, in order to ensure the rotation stability of the handle 100 , two curved arms 110 are provided, and two connecting arms 240 are respectively provided on the outsides of the two curved arms 110 , and the rotating shaft 600 passes through the curved arms 110 and the connecting arms 240 .

[0073] The handle base 200 is a fixed structure. When the user pulls the handle 100 outward, the curved arm 110 rotates on the rotating shaft 600, so that the handle 100 rotates outward.

[0074] In this embodiment, a reset structure is also provided, and the handle 100 can automatically reset after the door is opened. The specific implementation is as follows: a reset torsion spring 700 is sleeved on the rotating shaft 600, and the first torsion portion 710 of the reset torsion spring 700 is fixed on the bent arm 110, and the second torsion portion 720 is fixed to the handle seat 200.

[0075] Specifically, in this embodiment, the first torsion portion 710 is at least one torsion foot of the return torsion spring 700, and the second torsion portion 720 is a bend portion disposed in the middle of the return torsion spring 700;

[0076] The handle base 200 is provided with a hook 230 capable of hooking the bent portion.

[0077] Reference Figure 5 As shown, in this embodiment, the torsion feet at both ends of the reset torsion spring 700 are set as the first torsion part 710, and the two torsion feet are installed on the bending arm 110 through the torsion groove; at the same time, an extended bending part is set in the middle part of the reset torsion spring 700, which extends toward one side of the handle seat 200 and is hooked with the hook 230 on the handle seat 200.

[0078] When the user operates the handle 100 to rotate outward, the two first torsion parts 710 rotate together with the bent arm 110 and approach the second torsion part 720. At this time, the return torsion spring 700 is in a torsion state;

[0079] After the door is opened and the external force on the handle 100 is removed, the reset torsion spring 700 is reset, so that the two first torsion parts 710 rotate back toward the side away from the second torsion part 720, thereby driving the curved arm 110 to rotate, thereby resetting the handle 100.

[0080] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
