Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts assembly, in particular to a novel handle fastening structure. Background Art

[0002] The difference between a lift-type door handle and an ordinary door handle is that an ordinary handle rotates to the left or right side of the car when opened, while a lift-type door handle rotates upward. Because the handle needs to be rotated from the outside of the car to the inside of the car, three fastening points are required during the installation of the handle and the door, namely Figure 1 The first fastening point 1, the second fastening point 2, and the third fastening point 3 shown in the figure form a stable assembly. If the third fastening point is in the form of a bolt, it will take up a larger motion envelope, which will cause assembly interference and make it impossible to assemble. After the handle reaches the assembly position, the door sheet metal cannot provide the flange surface required for bolt fastening. To solve the above problem, the sheet metal needs to be raised to the following position: Figure 2 The bolt installation structure 4 shown in the figure has a protrusion of more than ten millimeters to cooperate with the bolt fastening point, but this structure cannot be stamped out of sheet metal. The sheet metal at this location is the inner reinforcement sheet of the car door, and there are multiple stamping and welding processes. Even if the fastening structure can be manufactured, the position accuracy of the structure will be between ±2mm. This accuracy is too low, which will cause deformation and interference problems in engineering and cannot meet assembly requirements. Utility Model Content

[0003] The purpose of the utility model is to provide a novel handle fastening structure to solve the problems raised in the above-mentioned background technology that if the fastening points of the existing handle and the door are in the form of bolts, a larger motion envelope will be required, which will cause assembly interference and make it impossible to assemble. The door sheet metal needs to be raised to form a raised bolt installation structure of more than ten millimeters in order to cooperate with the bolt fastening point, and the raised structure is not easy to manufacture and has poor precision.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new handle fastening structure, including a pressing plate, one end of which is rotatably mounted on an axle pin on a handle seat, a baffle is provided on the handle seat, a card slot is provided on the handle mounting portion, the baffle and the card slot are respectively matched with the end of the pressing plate, and a self-locking structure is provided on the handle seat between the baffle and the card slot.

[0005] The baffle and the card slot are configured as plastic parts.

[0006] The end edge of the slot is arranged as a circular chamfered structure.

[0007] The shaft pin is fixed on the handle seat through a nut, a mounting hole is arranged at the end of the pressing sheet, and the middle part of the shaft pin passes through the mounting hole on the pressing sheet.

[0008] The surface of the self-locking structure is arranged as an inclined surface rising from one side of the blocking piece to one side of the card slot.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The utility model has a simple structure for assembly and can be pushed in and locked manually to achieve self-locking and anti-retraction. It is easy to disassemble and can be disassembled by lightly prying the pressure piece with a flat-blade screwdriver to make it pass over the self-locking structure.

[0011] 2. When the space is insufficient, the utility model changes the form of the fastening points to ensure the number and strength of the fastening points. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] like Figure 3-6As shown, the handle fastening structure provided by the utility model includes a pressing plate 5, one end of which is rotatably mounted with the axle pin 7 on the handle seat 6, the axle pin 7 is fixed to the handle seat 6 by a nut 10, the handle seat 6 is fixed to the door sheet metal, a baffle 8 is provided on the handle seat 6, and a handle mounting portion 14 is provided with a slot 9, the baffle 8 and the slot 9 are respectively matched with the end of the pressing plate 5, in the utility model, the installation position of the axle pin in the fastening structure is moved upward, the axle pin 7 is fixed to the handle seat 6 by a nut 10 pre-embedded in the handle seat 6, the pressing plate 5 is pressed by the nut on the head of the pin shaft, the pressing plate 5 can rotate with the axle pin 7 as the rotating axis, and the end of the pressing plate 5 away from the axle pin 7 can achieve staying in the pre-assembly position and self-locking in the assembly position. Before loading the handle, Figure 3 As shown, the pressing piece 5 stays in the pre-assembly position. A baffle 8 is provided on the handle seat 6 at the pre-assembly position to prevent the pressing piece 5 from rotating arbitrarily into the assembly position before assembly. The baffle 8 is an elastic plastic part. When assembling and tightening, the pressing piece 5 can be pushed. After the baffle 8 is slightly deformed, the pressing piece 5 releases the matching relationship with the baffle 8. The pressing piece 5 continues to be rotated and pushed into the card slot 9 at the assembly position. Figure 4 The pressing piece 5 shown in the assembly position fastens the mounting portion of the handle to the handle seat 6 through the clamping groove 9 and shares the destructive force with the other two fastening bolts 13 .

[0022] A self-locking structure 11 is provided on the handle seat 6 between the baffle 8 and the card slot 9. The surface of the self-locking structure 11 is provided as an inclined surface which rises from the baffle 8 side to the card slot 9 side. When the pressing piece 5 is pushed from the pre-assembly position to the assembly position, it will gradually rise along the slope on the self-locking structure 11 and pass over the self-locking structure 11 to reach the assembly position. After reaching the assembly position, the self-locking structure 11 can prevent the pressing piece 5 from sliding out of the card slot 9 at the assembly position. At this time, the pressing piece 5 forms a fastening with the handle mounting portion 14.

[0023] The card slot 9 is configured as a plastic part, and the end edge of the card slot 9 is configured as a circular chamfered structure. After the pressing piece 5 passes over the self-locking structure 11, the pressing piece 5 contacts the circular chamfered structure of the card slot 9, and the pressing piece 5 continues to rotate, lifts the top of the card slot 9 and then enters the card slot 9.

[0024] The assembly process of the utility model: Figure 7 After the handle is rotated and installed into the handle seat 6, the three elastic claws 12 hook the handle seat 6 to form a pre-installation; then two of the three fastening points are tightened with the fastening bolts 13 respectively, and then the pressing piece 5 of the third fastening point is rotated to complete the assembly.
