Description

Technical Field

[0001] The utility model belongs to the technical field of starting motor protection, and in particular relates to a starting motor protection mechanism. Background Art

[0002] During the starting process of a car engine, a motor is usually required to drive the engine output shaft to rotate, providing initial power for the engine rotation to activate the engine. When starting the engine, the current starter motor usually connects the motor and the engine through a one-way device to achieve connection and disconnection between the motor and the engine. When the starter motor is installed and used, a protective shell is generally fixed on its surface, so that the surface of the starter motor can be protected from collision in the event of a collision. However, since the starter motor and the protective shell are fixedly connected by screws, it is difficult to align the screw holes when installing the protective shell, and tools are required, which makes the installation work more troublesome. For this reason, we propose a starter motor protection mechanism. Utility Model Content

The connecting blocks 101 are slidably connected to the connecting grooves 100 to facilitate the connection between the protective shell 2 and the motor body 1.

[0032] In this embodiment, preferably, the guide assembly includes guide grooves 200 symmetrically opened on both sides of the connecting block 101 and guide blocks 201 symmetrically fixed on both sides of the inner wall of the connecting groove 100. The guide blocks 201 are slidably connected to the guide grooves 200, so that the connecting block 101 plays a guiding role when connected to the connecting groove 100.

[0033] In this embodiment, preferably, the limiting assembly includes a limiting groove 300 opened inside the connecting groove 100 and a built-in groove 301 opened at the end of the connecting block 101, and a limiting buckle 302 is arranged inside the built-in groove 301.

[0037] The working principle and use process of the utility model: when the protective shell 2 and the motor body 1 need to be installed, the protective shell 2 is first sleeved from the end of the motor body 1 to the surface, so that the connecting block 101 is embedded in the interior of the connecting groove 100, and drives the guide groove 200 to slide and connect with the guide block 201, and at the same time squeezes the limit buckle 302. The limit buckle 302 is squeezed by the external force to retract the telescopic spring 303 into the interior of the built-in groove 301, and drives the slider 401 to slide in the interior of the slide groove 400 to play a moving guide role, and then continues to push the protective shell 2, so that it drives the connecting block 101 to completely slide and embed into the interior of the connecting groove 100. At this time, the limit buckle 302 is reset from the interior of the built-in groove 301 under the action of the telescopic spring 303 and pops out and is stuck in the limit groove 300 Inside, the protective shell 2 can be temporarily limited on the surface of the motor body 1, and the positioning hole 500 and the screw hole 501 are accurately aligned, and then the positioning screw 502 is used to pass through the surface of the protective shell 2 through the inside of the screw hole 501 and connect with the positioning hole 500, and finally the positioning screw 502 is tightened to make it screwed and fixedly connected with the positioning hole 500, so that the protective shell 2 can be fixedly installed on the surface of the motor body 1 for protection. When the motor body 1 needs to be wired, first pull the pull ring 602 to drive the dust plug 600 to move from the inside of the power connection port 3, and drive the rubber block 601 to be squeezed and separated from the power connection port 3, so that the dust plug 600 can be withdrawn from the inside of the power connection port 3, and then the power cord can be plugged into the power connection port 3.
