Description

Technical Field

[0001] The utility model relates to the technical field of automobile dust covers, in particular to an anti-falling automobile dust cover. Background Art

[0002] As the actuator of the automobile steering system, the steering gear converts the rotation of the steering wheel into translation. Its performance directly affects the comfort, safety and NVH performance of the vehicle. Since the steering gear input shaft passes through the hole of the vehicle body, a dust cover is required to seal the body sheet metal to prevent the noise from the front cabin and the mud and sand on the ground from entering the car compartment, so the sealing performance of the dust cover is very important. The car often encounters bumps and vibrations during driving. The existing dust cover is only fixed to the steering gear by a buckle structure. In a long-term vibrating working environment, the buckle is easy to loosen and break, causing the dust cover to fall off. Therefore, an anti-falling automobile dust cover is needed. Utility Model Content

[0003] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.

[0004] In order to solve the technical problems mentioned in the above background technology part, some embodiments of the present application provide an anti-falling automobile dust cover, including a frame, reinforcing ribs fixed on the frame, a dustproof mechanism sleeved on the frame, a first fixing mechanism fixed on the frame, a second fixing mechanism fixed on the first buffer mechanism, and a sealing mechanism fixed on the frame; the first fixing mechanism includes a first through hole fixed on the frame, a trapezoidal groove symmetrically fixed on the frame, a circular groove symmetrically fixed on the frame, a second through hole symmetrically fixed on the frame, a first protrusion fixed on the frame, and a second protrusion fixed on the trapezoidal groove. The frame is used to support the dustproof mechanism and is made of nylon 6 material with a glass fiber addition ratio of 30%; the reinforcing ribs can enhance the strength and rigidity of the frame without increasing the wall thickness, so as to save material consumption, reduce weight and reduce manufacturing costs; the dustproof mechanism is mainly used for dustproof and soundproofing to prevent noise from the front cabin and mud and sand on the ground from entering the car compartment; the first fixing mechanism and the second fixing mechanism jointly fix the device as a whole on the sheet metal and the steering gear to prevent it from falling off; the sealing mechanism is used for sealing to prevent mud and sand from entering the dust cover; the steering gear passes through the first through hole; the trapezoidal groove is connected to the circular groove, and one end of the trapezoidal groove connected to the circular groove is narrower and the other end is wider. Since the trapezoidal groove and the circular groove are both located on the inner side of the frame, it is not convenient to align the notch of the trapezoidal groove with the connecting part of other devices during installation, and one end of the trapezoidal groove is wider to facilitate blind insertion; during installation, when the connecting part is inserted into the trapezoidal groove and contacts the second protrusion, the second protrusion will slightly squeeze the connecting part, so that the insertion feel changes, which can remind the installer that it is about to be fully inserted, which is convenient for the installer to operate blindly; the second through hole is used to install screws.

[0005] Specifically, the dustproof mechanism includes a dust cover mounted on the frame, a plurality of first mounting grooves fixedly mounted on the dust cover, a second mounting groove fixedly mounted on the dust cover, a valve fixedly mounted on the dust cover, and a buffer assembly fixedly mounted on the dust cover. The dust cover is made of EPDM rubber, which has excellent aging resistance and is widely used in automotive parts; the dust cover is connected to the frame through the first mounting groove and the first protrusion, and one side of the dust cover wraps around the frame so that the dust cover can be fixed on the frame; the valve contacts the frame, and forms a dustproof and soundproof sealed cavity with the frame and the dust cover, which plays a role in reducing the external noise from entering the cockpit, and its soundproof effect is more obvious; the buffer assembly can reduce vibration.

[0006] Specifically, the buffer assembly includes a plurality of first pads fixedly mounted on the dust cover. The dust cover is provided with a plurality of circles of first pads, and the dust cover is made of rubber material and is easily deformed after being squeezed. The first pads are squeezed by the front panel of the vehicle body after bumps and vibrations, and are deformed and closely fit with the front panel of the vehicle body, thereby reducing dust and noise from entering the cab. At the same time, the first pads also provide a certain deformation space for the dust cover, thereby playing a role in buffering and shock absorption.

[0007] Specifically, the sealing mechanism includes a plurality of third through holes fixedly arranged on the frame, a sealing ring fixedly arranged on the third through hole and the frame, and a plurality of second pads fixedly arranged on the sealing ring. The sealing ring is provided with a protrusion which can be inserted into the third through hole; the sealing ring is made of thermoplastic vulcanized rubber and plays a sealing role to prevent sand and dust from entering the dust cover; the second pad can give the sealing ring a certain deformation space and cooperate with the sealing ring to play a role of sealing and buffering shock absorption.

[0008] Specifically, the second fixing mechanism includes a liner fixed on the second mounting groove, a plurality of buckles fixed on the liner, and a clamping piece fixed on the liner. The liner is made of nylon 66, which has high mechanical strength and hardness and great rigidity; the buckle is used to buckle the clamping piece on the sheet metal part, and the clamping piece is connected to the buckle on the sheet metal part to play a fixing role.

[0009] The beneficial effects of the utility model are:

[0010] (1) Both ends are equipped with fixing mechanisms to prevent the dust cover from falling off.

[0011] (2) The trapezoidal groove and the second protrusion on the first fixing mechanism facilitate blind operation by the installer, and the installer can judge whether the installation is in place by feel.

[0012] (3) A valve is provided, which contacts the frame and forms a dustproof and soundproof sealed cavity with the frame and the dust cover, thereby reducing the external noise from entering the cockpit and achieving a more obvious soundproof effect. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the trapezoidal groove is wider to facilitate blind insertion. During installation, when the connecting part is inserted into the trapezoidal groove and contacts the second protrusion, the second protrusion will be slightly The slightly squeezed connecting part changes the insertion feel, which can prompt the installer that it is about to be fully inserted, making it easier for the installer to operate blindly; the dust cover is wrapped on the steering gear, and the valve is in contact with the frame, forming a dust-proof and sound-proof sealed cavity with the frame and the dust cover, which reduces the external noise entering the cockpit; the first pad is squeezed by the front panel of the vehicle body after the bumps and vibrations, and is deformed and fits tightly with the front panel of the vehicle body, reducing the dust and noise entering the cab. At the same time, the first pad also gives the dust cover a certain deformation space, which plays a role in buffering and shock absorbing; the second pad cooperates with the sealing ring to play a role of sealing and buffering and shock absorbing.
