Description

Tow hook cover plate mounting structure

Technical Field

The utility model belongs to the technical field of the car, a tow hook apron mounting structure is related to.

Background

When a car is anchored, it is sometimes necessary to tow the car away with a tow hook. The existing trailer hook is not generally installed and fixed on an automobile, but is placed in a trunk of the automobile and then fixed on the automobile when the trailer hook needs to be used. In order to facilitate the installation of the towing hook, a connecting hole is correspondingly arranged on the bumper generally, the connecting hole is covered by a towing hook cover plate when the towing hook is not used, and the towing hook cover plate is opened when the towing hook is used.

The common mounting structure of tow hook apron at present has prized formula joint structure. Chinese patent literature document discloses a cover plate for an automobile tow hook [ application number: 201510325224.4, respectively; publication No.: 104972852A ], the tow hook blanking cap matches with the mounting groove that sets up on the bumper of car, is provided with the side cantilever card in the both sides of tow hook blanking cap and grabs, and the back that the side cantilever card grabbed is provided with spacing muscle, and when the tow hook blanking cap was installed on the mounting groove, spacing muscle was used for spacing the tow hook blanking cap in the fore-and-aft direction of car and left and right directions. Can make the tow hook blanking cover fixed firm through setting up spacing muscle, nevertheless make the side cantilever card grab difficult production to warp and deviate from the mounting groove in for the tow hook blanking cover is opened inconveniently.

The common mounting structure of the trailer hook cover plate is also provided with a clamping structure with a rotating point. Chinese patent literature document publication proposes a tow hook cover plate for an automobile bumper [ application No.: 201020622856. X; the notice number is: 201872555U ], including a molding surface facing the outside of the bumper and a structural surface facing the inside of the bumper, two bosses diametrically opposed on the periphery of the structural surface, a joint and a catch diametrically opposed on the periphery; the connecting line of the two bosses forms a rotating shaft of the towing hook cover plate, and the connecting line of the joint part and the buckle is vertical to the rotating shaft. The joint part corresponds to the opening end of the tow hook cover plate, and the arrow-shaped anti-falling part extends out of the periphery of the structural surface and is positioned between the boss and the joint part, and the anti-falling part is used for preventing the tow hook cover plate from falling off or losing from the vehicle body after being opened. When the towing hook cover plate is opened, the opening end is pressed down by hands, the towing hook cover plate rotates around the rotating shaft, the buckle is separated from the bumper, then the position of the buckle is held, and the towing hook cover plate is taken out of the bumper. There is also certain angle requirement when taking out the tow hook apron, need pay attention to the position of two bosss and joint, prevents to block, leads to the opening operation of tow hook apron inconvenient like this.

The groove wall at the inner end of the sliding groove 1b1 is provided with a convex limiting bulge, the rotating shaft head 2d can be stopped at the limiting bulge, and the limiting bulge is used for limiting the sliding length of the cover plate body 2. The mounting surface 1b7 is also provided with a convex stop 1b2, a stop 1b3 and a stop block 1b 4. The stopper 1b2 is located inside the fixing portion 2a, and the fixing portion 2a can be stopped by the stopper 1b2, and the stopper 1b2 is used for preventing the fixing portion 2a from rotating towards the inner end of the connecting hole 1 b. The stopper 1b3 is located at the inner side of the sliding groove 1b1, the opening part 2b can stop at the stopper 1b3, and the stopper 1b3 is used for limiting the rotation angle of the opening part 2b when the opening part 2b is pressed; meanwhile, the cover plate body 2 can abut against the stop block 1b3 to slide towards the limiting surface 1b8, and the stop block 1b3 has limiting and guiding functions, so that the cover plate body 2 can slide towards the limiting surface 1b8 to open the connecting hole 1b conveniently. The stopper 1b4 is located inside the inner end of the sliding groove 1b1, that is, the stopper 1b4 and the stopper surface 1b8 are respectively located at two sides of the sliding groove 1b1, and when the cover plate body 2 slides, the opening portion 2b can be inserted between the stopper 1b4 and the stopper surface 1b 8. The mounting surface 1b7 is further provided with a convex clamping protrusion 1b5, the outer surface of the clamping protrusion 1b5 is a spherical surface, the two clamping protrusions 1b5 are oppositely arranged, and when the clamping salient point 2e is clamped into the clamping groove 1b6, the two clamping protrusions 1b5 are positioned at two sides of the opening part 2b and abut against the opening part 2 b.

As shown in fig. 6, the engaging protrusion 2e is engaged into the engaging groove 1b6, the engaging protrusion 1b5 abuts against the opening portion 2b, the cover body 2 closes the engaging hole 1b, and the cover body 2 is fixed in the engaging hole 1 b. When the cover plate of the trailer hook needs to be opened, as shown in fig. 7, the opening part 2b is pressed inwards, the clamping salient point 2e is separated from the clamping groove 1b6, the cover plate body 2 rotates around the rotating shaft, and the fixed state of the cover plate body 2 and the mounting seat 1a is released. Then as shown in fig. 8, the cover plate body 2 is slid along the sliding groove 1b1 to a direction close to the limiting surface 1b8, the cover plate body 2 is turned over, the opening part 2b is inserted between the limiting block 1b4 and the limiting surface 1b8 until the rotating shaft head 2d abuts against the limiting protrusion, the outer surface of the cover plate body 2 abuts against the limiting surface 1b8, and the cover plate body 2 is received in the side of the connecting hole 1b where the limiting surface 1b8 is arranged, so that the connecting hole 1b is opened. Make apron body 2 revolute the rotation of axes and remove fixed state through pressing opening portion 2b, because joint bump 2 e's surface is spherical, joint bump 2e is spherical head promptly, has the guide effect, and joint bump 2e card is gone into joint groove 1b6 and is deviate from joint groove 1b6 and all very light convenience, and joint bump 2 e's stable in structure makes apron body 2 fixed stable simultaneously, reduces the poor clearance of face. After the fixed state is released, the cover plate body 2 only needs to slide along the sliding groove 1b1 to enable the cover plate body 2 to be folded at one side of the connecting hole 1b provided with the limiting surface 1b8, the cover plate body 2 does not need to be taken out, the sliding direction and angle do not need to be specially noticed, and the cover plate of the trailer hook is convenient to open.
