Description

Technical Field

[0001] The utility model relates to the technical field of starters, in particular to a starter front cover. Background Art

[0002] The starter cover is a cover installed in front of the starter. It is usually a protective cover made of metal or plastic, used to cover the front of the starter and protect the internal components of the starter from the impact and damage of the external environment. The design of the starter cover can prevent dust, water vapor, grease and other impurities from entering the starter, and it can also play a role in heat insulation, sound insulation and protection. The installation position and shape of the starter cover will vary depending on different vehicles or equipment, but its main function is to protect the starter and increase its service life.

[0003] For example, the Chinese patent with publication number CN204729207U discloses an improved starter front cover, including a flange cover and a main body cover, wherein the right end of the main body cover is provided with a flange cover, the main body cover is screwed with the flange cover, the left center of the flange cover is provided with an electric drive device limiting hole, the right part of the electric drive device limiting hole is provided with a transmission shaft hole, a bearing is provided in the transmission shaft hole, an oil seal is provided on the right part of the transmission shaft hole, a locking screw hole is provided at the right end of the main body cover, locking through holes corresponding to the locking screw holes are provided around the flange cover, a locking through hole is provided in the locking through hole, a locking bolt is provided, a fixing lug is provided on the outside of the flange, and a fixing mounting hole is provided on the fixing lug. The utility model sets the flange cover and the main body cover as two separate detachable cover bodies, and through the free combination of the locking through hole and the locking screw hole, the flange cover can be assembled and used with a plurality of main body covers of different sizes, thereby achieving the benefits of convenient installation and reduced cost.

[0004] However, in actual use, this solution only uses bolts to fix the front cover, and the connection method is very simple. When the bolts and screws are rusted or broken, the starter and the front cover are very likely to loosen, thereby affecting the normal operation of the starter. At the same time, when the starter is used for a long time, dust accumulates on the front cover. This solution lacks an automatic dust cleaning mechanism and has low practicality. Utility Model Content

[0005] In view of the above problems, the utility model proposes a starter front cover to solve the defects of the existing starter front cover having a single and unstable fixing method and having no dust cleaning function.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A starter front cover comprises a connecting port, a front cover and a reinforcement mechanism, wherein the reinforcement mechanism comprises a protrusion, a circular hole, a groove, a hollow cylinder, a positioning pin, a limit block, a return spring and a lifting cap, wherein the protrusion is fixedly connected to one end of the front cover, a groove is provided at one end of the connecting port close to the front cover, a circular hole is provided on the surface of the protrusion, a hollow cylinder is fixedly connected to the outer wall of the connecting port, a positioning pin is inserted into the interior of the hollow cylinder, a lift cap is fixedly connected to the top of the positioning pin, a return spring is sleeved on the exterior of the positioning pin, and a limit block is fixedly connected to the bottom of the return spring.

[0008] A further improvement of the technical solution of the utility model is that a cleaning mechanism is arranged inside the front cover, and the cleaning mechanism includes a rotating handle, a ventilation grille, a filter, a strip plate, a brush, and an ash box. A ventilation grille is opened at the front end of the front cover, and the inner wall of the front cover is fixedly connected to the filter. The rotating handle is movably connected to the front cover and passes through the ventilation grille and the filter, and the other end of the rotating handle is fixedly connected to the strip plate, and the side of the strip plate close to the filter is fixedly connected to the brush.

[0009] By adopting the above technical solution, the brush in the solution can sweep the dust accumulated on the filter net into the dust collection box, preventing the dust accumulation from affecting the working efficiency of the starter, and improving the cleaning efficiency of the device.

[0010] A further improvement of the technical solution of the utility model lies in that: the outer walls of the connecting port and the front cover are respectively fixedly connected with a first connecting ear and a second connecting ear, the first connecting ear and the second connecting ear are fixedly connected by a fastening bolt, and four groups of the first connecting ear and the second connecting ear are arranged, which are distributed in a ring around the outer walls of the connecting port and the front cover.

[0011] By adopting the above technical solution, a total of four groups of first connecting ears and second connecting ears are provided in the solution, which can preliminarily fix the front cover to prevent it from loosening.

[0012] A further improvement of the technical solution of the utility model is that: the positioning pin passes through the hollow cylinder and the limiting block, the protrusion is matched with the groove, and when the protrusion is inserted into the groove, the circular hole is coaxial with the positioning pin.

[0013] By adopting the above technical solution, after the protrusion in the solution is inserted into the groove, it is fixed by the positioning pin to prevent it from falling off, thereby further increasing the stability of the front cover fixation.

[0014] A further improvement of the technical solution of the utility model is that: the reinforcement mechanism is provided with at least three groups, which are evenly distributed around the connecting port and the circular surface of the front cover.

[0015] The above technical solution is adopted, in which at least three groups of reinforcement mechanisms are provided, so that even if one of the groups fails, the front cover can still be effectively fixed at the connection port, thereby preventing the risk of the front cover falling off.

[0016] A further improvement of the technical solution of the utility model is that: a square groove begins to be formed at the bottom end of the inner wall of the front cover, the position of the square groove is just below the brush, and the dust collecting box is clamped in the square groove.

[0017] By adopting the above technical solution, the dust collecting box in the solution can collect the dust dropped by the brush to prevent the dust from accumulating on the inner wall of the front cover, thereby improving the cleaning effect of the device.

[0018] A further improvement of the technical solution of the utility model is that one end of the strip plate is closely fitted with the end surface of the rotating handle, the rotating handle is coaxially arranged with the front cover, and the tail of the brush is fitted with the filter.

[0019] By adopting the above technical solution, the rotation of the rotating handle in the solution can drive the strip plate to rotate, so that the brush rotates in a circle, and the filter net can be completely cleaned.

[0020] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0021] 1. The utility model provides a starter front cover, which adopts the cooperation of a protrusion, a round hole, a groove, a hollow cylinder, a positioning pin, a limit block, and a reset spring. First, a fastening bolt is driven into the first connecting ear and the second connecting ear to complete the preliminary fixation, and then the protrusion is inserted into the groove for positioning, and then the positioning pin is inserted into the round hole on the surface of the protrusion through the deformation force of the reset spring to complete the fastening, so that the front cover is fixed on the connecting port through two fixing methods, avoiding the risk of unstable fixing of the front cover and easy falling off caused by adopting a single fixing method, and achieving the effect of stable fixing of the front cover.

[0022] 2. The utility model provides a starter front cover, which preliminarily filters the dust in the external air through the filter net, and then drives the strip plate and the brush to rotate by turning the rotating handle, so that the brush sweeps the dust accumulated on the filter net and finally drops it into the dust collecting box, thereby preventing the dust from entering the starter and increasing the cleaning efficiency of the equipment.
