Detailed Description

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

The present embodiment relates to a door handle structure including a door lock having a key cylinder, a door handle case, and a seal as a whole.

The door lock is fixedly arranged on a door lock mounting part, a door handle shell is matched with the door lock mounting part to cover a lock cylinder, and a key through hole arranged corresponding to the lock cylinder is constructed on the door handle shell; a seal is connected between the lock cylinder and the door handle housing, and the seal is configured to encircle the key through hole and the lock cylinder arrangement and to seal a gap between the lock cylinder and the door handle housing.

The door handle structure of this embodiment owing to increase the sealing member between door handle lock core position and door handle shell, through the leakproofness that improves door handle keyhole position to can effectively prevent the waterproof inefficacy in gap between lock core and the door handle shell, and can effectively improve noise in the car, have better practicality. The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Example one

Based on the above overall structure description, an exemplary structure of the door handle structure of the present embodiment is as shown in fig. 1 and fig. 2, and for convenience of description, the structure of the door lock mounting portion 4 is first specifically described below, in this embodiment, the door lock mounting portion 4 is specifically an existing door handle base mounted on a vehicle, the lock cylinder 1 is fixedly connected to the door handle base, and an end of the lock cylinder 1 provided with a key insertion hole is arranged toward the outside of the vehicle.

The door handle shell 2 is also of the existing structure, the door handle shell 2 is matched with the door handle base to cover the lock cylinder 1, a key through hole 201 arranged corresponding to the lock cylinder 1 is formed in the door handle shell 2, when the door is opened, a key penetrates through the key through hole 201 in the door handle shell 2 and then is inserted into the key insertion hole in the lock cylinder 1, and the lock cylinder 1 can be rotated to open and close the door lock. In this structure, a flange 202 provided in the circumferential direction of the ring key passing hole 201 is formed in the door handle case 2, and the flange 202 is bent toward the key cylinder 1 side, which is advantageous for mounting the seal 3 described below.

The door handle structure of the present embodiment includes, but is not limited to, a seal 3 provided between the lock cylinder 1 and the door handle housing 2, and as shown in fig. 3, the seal 3 is substantially in the shape of a sleeve, which is connected between the lock cylinder 1 and the inner wall of the door handle housing 2. Specifically, the seal 3 has a mounting portion 301 fixed to one of the key cylinder 1 and the door handle housing 2, and an abutting portion 302 abutting on the other of the key cylinder 1 and the door handle housing 2, and the abutting portion 302 is integrally formed with the mounting portion 301.

In order to facilitate the installation, referring to fig. 3, in this embodiment, the installation portion 301 is fixedly connected to the lock cylinder cap 101 of the lock cylinder 1 in a sleeving manner, here, the lock cylinder cap 101 is an existing structure fixedly connected to the lock cylinder 1, and the lock cylinder sleeve 102 is further sleeved outside the lock cylinder 1. In order to prevent the sealing element 3 from falling off from the lock cylinder cap 101, the mounting part 301 is provided with a mounting end 3011 extending inwards along the radial direction of the lock cylinder 1, the mounting end 3011 is in a circular ring shape, and the mounting end 3011 is clamped between the lock cylinder clamping sleeve 102 and the lock cylinder cap 101, so that the mounting stability of the sealing element 3 can be greatly improved.

The abutting portion 302 is formed integrally with the mounting portion 301, is provided around the aforementioned burring 202, and abuts against the inner wall of the door handle housing 2. The abutting portion 302 abuts specifically against a connecting portion of the flange 202 and the edge of the key passing hole 201, so that a gap between the outer wall of the lock cylinder 1 and the door handle housing 2 can be sealed.

In order to improve the sealing performance, in the above structure, the sealing member 3 is preferably made of an elastic material, such as silicon rubber, etc., and the elastic material is selected not only to facilitate assembly, but also to provide a contact pressure to compensate for a leakage gap by utilizing the characteristic of easy deformation of the elastic material.

Therefore, when the seal 3 is actually designed, the abutting portion 302 has a shape that is close to the position of the door handle case 2 with which it abuts, and thus the contact area can be increased, and the sealing effect can be improved. Further, the abutting portion 302 is designed to be larger than the actual installation space thereof, so that the inner wall of the door handle housing 2 presses the abutting portion 302 to be deformed after the door handle housing 2 is assembled, thereby improving the sealing effect.

It should be noted that, from the mounting portion 301 to the abutting portion 302, the outer wall of the mounting portion 301 is stepped, and the diameter of the outer wall is gradually increased, which is not only beneficial to mounting, but also provides the sealing element 3 with better sealing performance.

Example two

The present embodiment relates to a door handle structure, which is substantially the same as the first embodiment, and mainly differs in the installation positions of the attachment portion 301 and the abutting portion 302.

Referring to fig. 4 to 6, in the present embodiment, the mounting portion 301 is fitted over the burring 202, and the abutting portion 302 abuts against the plug cap 101 of the plug 1. In order to obtain a better sealing effect, in this embodiment, the abutting portion 302 is shaped like an outwardly expanding trumpet, and the actual size of the abutting portion 302 is still larger than the actual installation space thereof, so that the abutting portion can be better abutted with the lock cylinder cap 101 to improve the sealing performance.

Further, a retaining structure is provided between the flange 202 and the mounting portion 301, and the retaining structure provides a restraint against the seal 3 being released from the flange 202. Specifically, the retaining structure includes a protrusion 2021 provided on the flange 202, and a groove 303 configured on the seal member 3 and into which the protrusion 2021 is fitted. In this embodiment, the specific circumferential arrangement of the protrusion 2021 around the flange 202 can further improve the sealing performance, and of course, in addition, the protrusion 2021 may also be in a multi-segment shape formed by the flange 202, or the protrusion 2021 may be disposed around the flange 202 as a whole, but a plurality of protrusions 2021 are disposed at intervals along the axial direction of the key passing hole 201.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
