Description

Technical Field

[0001] This utility model relates to the field of automotive mudguard technology, specifically an easy-to-install automotive mudguard. Background Technology

[0002] Car mudguards are plate-like structures installed behind the outer frame of the wheels, usually made of rubber, plastic, or metal. Their main function is to prevent mud, water, stones, and other debris splashed up by the vehicle while driving from hitting the car body and pedestrians, while also protecting the wheels and body from damage.

[0003] The prior art publication number CN222329839U discloses an easy-to-install and remove car mudguard, belonging to the field of car mudguards. This utility model provides an easy-to-install and remove car mudguard, including a mudguard sheet, a mudguard strip facing the tire on one side of the mudguard sheet, an extension strip on the other side of the mudguard sheet, a reinforcing block on one side of the extension strip, and a wrapping frame welded to both sides and the middle of the upper end of the mudguard sheet. Bolts for connection are provided on the side of the wrapping frame facing the reinforcing block. This utility model solves the problem that in the installation of existing car tire mudguards, the car tire itself can interfere with the insertion of a screwdriver, making rotation difficult and causing difficulties in installation and removal. This utility model uses the meshing connection between a first sector gear and a second sector gear to adjust the direction of rotation, so that the rotation of the transmission block, after transmission, can drive the bolt to rotate.

[0004] With the above configuration, the existing mudguard, by setting a wrapping frame, adjusts the rotation direction through a first sector gear and a second sector gear inside the wrapping frame. The protrusion of the second sector gear and the inclination of the first sector gear cause the transmission block connected to the first sector gear to face the extension strip. During installation and removal, the user can directly contact the transmission block from the outside and rotate the bolt, facilitating the installation and removal of the car mudguard with a screwdriver. However, the existing mudguard solution has the following drawbacks during operation: When installing the mudguards described in the prior art, the bolts need to be aligned with the threaded holes on the car body first, and then one of the rotating blocks is turned. However, during the rotation of one of the rotating blocks, the bolts will be threaded into the threaded holes, causing the other two bolts to shift and press against the car body, which will damage the car body. It will also cause the mudguards and mudguard strips to bend, resulting in the mudguards breaking. Utility Model Content

[0005] The present invention aims to provide an easy-to-install and disassemble car mudguard, mainly to solve the technical problem in the prior art where, when one of the bolts is threaded into the threaded hole on the car body, the other two bolts will press against the car body, causing damage to the car body, and also causing the mudguard to bend and break.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An easy-to-install and disassemble car mudguard includes a mudguard body, with fixed blocks fixedly connected to the upper two sides and the middle position of the mudguard body. The fixed blocks have a movable cavity inside, and a rotating groove is provided on one side of the movable cavity. A rotating rod is rotatably connected to the inner wall of the rotating groove. One end of the rotating rod is fixedly connected to a first bevel gear, and a drive assembly is installed on the inner wall of the other side of the movable cavity.

[0007] The working principle and beneficial effects of this utility model: 1. Working principle: When it is necessary to install the mudguard body, first hold the mudguard body and place it on the car body. At this time, use a screwdriver to turn the tightening block, so that the tightening block drives the rotating rod and the first bevel gear to rotate. The first bevel gear drives the second bevel gear to rotate, so that the threaded rod rotates together with the drive rod, so that the threaded rod is threadedly connected to the threaded hole. The fixing blocks are fixed in sequence to complete the installation.

[0008] 2. Beneficial effects: Existing technology uses a frame to adjust the rotation direction via a first and second sector gear inside the frame. The protrusion of the second sector gear and the tilt of the first sector gear cause the transmission block connected to the first sector gear to face the extension strip. This allows the user to directly contact the transmission block and rotate the bolts during installation and removal, facilitating the installation and removal of the car mudguard with a screwdriver. However, existing mudguard installation requires aligning the bolts with the threaded holes on the car body before turning one of the rotating blocks. This rotation causes the bolts to become threaded into the threaded holes, affecting the other two bolts. This can cause the mudguard to shift and press against the car body, damaging the vehicle and causing the mudguard and mud strip to bend, potentially leading to breakage. This solution addresses this by using a drive rod, sliding rod, locking block, and threaded rod. The drive rod rotates, causing the locking block to engage with the locking slot. The locking block then drives the sliding rod to rotate, which in turn drives the threaded rod. The threaded rod first connects to the fixing block via a threaded connection, and then to the threaded hole, thus securing the fixing block. This solution prevents the threaded rod from damaging the car body, as it does not extend beyond the outer wall of the fixing block when not rotating, thus avoiding damage to the vehicle body and preventing bending and breakage of the mudguard itself.

[0009] Preferably, the driving assembly includes a second bevel gear that meshes with a first bevel gear. A support plate is fixedly connected to the inner wall of the movable cavity. A driving rod is fixedly connected to one end of the second bevel gear, passing through the support plate and rotatably connected thereto. A sliding groove is formed on the side of the driving rod away from the second bevel gear. Symmetrical slots are formed on the inner wall of the sliding groove. A sliding rod is slidably connected to the inner wall of the sliding groove. Symmetrical locking blocks are fixedly connected to the outer wall of the sliding rod, slidingly connected to the inner wall of the slot. A threaded rod is fixedly connected to one end of the sliding rod, passing through the fixing block and threadedly connected thereto. By setting the driving assembly, the driving rod can be rotated, and the threaded rod can be threadedly connected to the threaded hole under the rotation of the driving rod, thereby fixing the fixing block.

[0010] Preferably, symmetrical abutments are fixed to the outer wall of the drive rod, and the abutments are in contact with both sides of the support plate. By setting the abutments, slippage of the drive rod during rotation can be prevented.

[0011] Preferably, a rotating ring is fixedly connected to the outer wall of the rotating rod, and the rotating ring is rotatably connected to the inner wall of the movable cavity. The rotating ring can limit the movement of the rotating rod and the first bevel gear.

[0012] Preferably, a screw-operated block is fixedly connected to the end of the rotating rod away from the first bevel gear. This allows the rotating rod to be turned with a screwdriver, thereby rotating the first bevel gear.

[0013] Preferably, a rubber pad is fixed to the side of the mudguard body that contacts the vehicle body. This prevents damage to the vehicle body from the fixing block and mudguard body when fixing the mudguard body. Attached Figure Description
