Description
Technical Field
[0001] This utility model relates to the field of hood protection technology, specifically a protective cover for the lock hole of an automobile hood. Background Technology
[0002] The car hood protects the engine and surrounding pipelines and other important components from adverse effects such as impact, corrosion, rain, and electrical interference, ensuring the normal operation of the vehicle.
[0003] When closing a car hood, the lock body is directly exposed to the outside, which can cause debris to fall into the lock body and cause blockages, affecting subsequent locking. Furthermore, when the hood is flipped down and latched, excessive external force can cause impacts and knocks to the lock body, greatly increasing the chance of damage after a collision. Summary of the Invention
[0004] The purpose of this utility model is to provide a protective cover for the lock hole of an automobile hood, in order to solve the problems mentioned in the background art, where when the current automobile hood is closed, the lock body is directly exposed to the outside, which can cause debris to fall into the lock body and cause blockage, affecting subsequent locking. Furthermore, when the hood is flipped down and fastened, excessive external force can cause impact and collision with the lock body, greatly increasing the probability of lock body damage after impact.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A protective cover for a car hood lock hole includes a main support rubber plate. A sealing edge strip is fixedly disposed on the outer edge of the main support rubber plate. The edge of the sealing edge strip is arc-shaped, and the bottom of the sealing edge strip is flat and recessed. The bottom surface of the sealing edge strip is adsorbed and bonded to the edge of the hood lock hole. A through groove is horizontally formed on the top surface of the main support rubber plate. A soft sealing rubber plate is horizontally fixedly disposed on the inner side of the through groove. The soft sealing rubber plate is made of soft rubber material and is fixedly connected to the inner edge of the through groove. The soft sealing rubber plate is made of elastic soft rubber material. A horizontal groove is formed on the top surface of the soft sealing rubber plate. The horizontal through-slot has open ends. The top surface of the soft sealing rubber plate has symmetrically opened end sleeve grooves at both ends of the horizontal through-slot. The top surface of the soft sealing rubber plate has a horizontally opened middle sleeve groove at the center of the horizontal through-slot, and the interior of the middle sleeve groove is connected to the horizontal through-slot. The top surface of the soft sealing rubber plate is symmetrically fixed to a buffer column, and the top of the buffer column is fixedly fixed to a mating head. The top surface of the soft sealing rubber plate is symmetrically fixed to an auxiliary soft plate, which is symmetrically fixed to the inner side of the through-slot near both ends. The top surface of the soft sealing rubber plate has symmetrically opened auxiliary through holes.
[0007] In a preferred embodiment of this utility model: the main support rubber plate is made of hard rubber material, and the shape of the main support rubber plate is consistent with the recessed groove of the car hood lock. The sealing edge rubber strip is made of soft rubber material, and the sealing edge rubber strip is fixedly installed at the three side edges of the main support rubber plate.
[0008] In a preferred embodiment of this utility model, the through-hole groove is horizontally opened at the center of the main support rubber plate, and the through-hole groove is opened in a cross shape. The shape of the soft sealing rubber plate is consistent with the shape of the through-hole groove, and the soft sealing rubber plate is made of soft rubber material.
[0009] As a preferred embodiment of the present invention: the horizontal through groove is horizontally through and located at the center of the top surface of the soft sealing rubber plate. There are two end sleeve grooves, and the two end sleeve grooves are parallel and symmetrically located at both ends of the horizontal through groove. The interior of the end sleeve groove and the interior of the horizontal through groove are connected to each other. The end sleeve groove and the middle sleeve groove are arranged in parallel to each other.
[0010] In a preferred embodiment of this utility model, there are two buffer columns arranged in parallel with each other. The two buffer columns are arranged in a tubular shape and are made of soft rubber material. The mating head is convex and fixedly installed at the top opening of the buffer column.
[0011] In a preferred embodiment of this utility model, the auxiliary through holes are symmetrically and through-shaped and are located near both ends of the centerline of the top surface of the soft sealing rubber plate, and the opening ends of the two buffer columns are fixedly connected to the openings of the auxiliary through holes to maintain communication.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This invention horizontally fastens the main support rubber plate inside the hood lock groove of a car. The sealing edge strip at the edge adheres to the groove, creating a sealed and fixed effect, making the main support rubber plate more stable and less prone to slippage. A horizontal through-slot is horizontally fitted at the opening of the lock hole, with the end sleeve groove and middle sleeve groove correspondingly fitted to the opening without obstructing the lock hole or affecting normal locking operation. When the hood flips down to engage, the lock body passes through the through-slot, end sleeve groove, and middle sleeve groove before being inserted into the lock body to lock. The hood, when flipped down, first contacts the mating head, pressing down on the buffer column. The buffer column cushions the hood, preventing damage from the impact of gravity. The integrated structure makes it more convenient to use, and the placement installation structure makes installation and use simple and efficient. Attached Figure Description
