Description

Technical Field

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

[0002] Starters are divided into DC starters, gasoline starters, compressed air starters, etc. according to their working principles. Most internal combustion engines use DC starters, which are characterized by compact structure, simple operation and easy maintenance. A gasoline starter is a small gasoline engine with a clutch and a speed change mechanism. It has high power and is less affected by temperature. It can start large internal combustion engines and is suitable for high-altitude cold areas. Compressed air starters are divided into two categories, one is to inject compressed air into the cylinder according to the working order, and the other is to use a pneumatic motor to drive the flywheel. The use of compressed air starters is similar to that of gasoline starters, and is usually used to start large internal combustion engines.

[0003] In the prior art, the patent number is: CN220434918U discloses an automobile starter, which relates to the field of starters, including a mounting frame, the left and right sides of the front of the mounting frame are symmetrically and movably connected with arc-shaped positioning blocks, a movable groove is opened in the middle of the front of the mounting frame, a starter body is installed in the middle of the front of the mounting frame, a flange is installed on the back of the mounting frame, the front of the mounting frame is movably connected with a positioning frame, the top and bottom of the front of the mounting frame are symmetrically opened with sliding grooves, the outer wall of the positioning frame is opened with a heat dissipation groove, and the top of the inner cavity of the positioning frame is fixedly connected with a heat dissipation fan. The automobile starter described in the utility model has a good reinforcement structure. When it is installed, the components on the front and back can prevent it from falling off. When it is used, the efficiency of use can be improved, and it is convenient to improve its heat dissipation.

[0004] Although the above-mentioned starter can achieve the effects of reinforcement and heat dissipation through the installation of a mounting frame and a cooling fan, in actual application, there are still the following shortcomings: the starter and the mounting frame are easily subjected to bumps and shakes, resulting in reduced performance and life of the starter. Utility Model Content

[0005] The utility model aims to provide a casing for a DC starter in view of the problems existing in the background technology.

[0006] To achieve this object, the utility model adopts the following technical scheme: a shell for a DC starter, including a base and a starter body, a plurality of damping shock absorbers are evenly fixedly installed on the bottom inner wall of the base, a protective shell is commonly fixedly installed on the top of the damping shock absorbers, an aluminum plate is fixedly installed on the bottom of the starter body, a plurality of bolts are evenly and symmetrically threaded on the top of the aluminum plate, the aluminum plate is fixedly installed on the bottom inner wall of the protective shell by the plurality of bolts, the output end of the starter body passes through the left wall of the protective shell, a plurality of buffer springs are fixedly connected to the front and rear outer walls of the protective shell, and the ends of the buffer springs away from the protective shell are commonly fixedly connected to the buffer plate, and a top cover is fixedly installed on the top of the base.

[0007] Preferably, a plurality of heat dissipation openings are provided on the left wall of the base.

[0010] Preferably, limiting grooves are provided on the left and right inner walls of the base.

[0011] Preferably, the left and right outer walls of the protective shell are fixedly connected with sliders, and the sliders are slidably connected to the corresponding limiting grooves.

[0012] The beneficial effects of the utility model are as follows: when the device encounters bumps, the protective shell slides up and down inside the base through the cooperation of the limit groove and the slider, and the setting of multiple damping shock absorbers can reduce most of the vibrations, so that the protective shell can be more stable, thereby making the starter body more stable, and at the same time, the buffer springs and buffer plates fixedly installed on the front and rear sides of the protective shell can increase the buffering performance of collisions with other objects, so that the device can avoid the influence of bumps and shaking on the working performance and life of the starter body; when the starter body needs to be inspected and repaired, it is only necessary to first unscrew the second bolt on the top of the top cover, and then unscrew the multiple bolts on the top of the aluminum plate to take out the starter body, so that the device is convenient for the staff to inspect and repair the starter body.

[0023] In this embodiment: a plurality of heat dissipation ports 9 are provided on the left wall of the base 1, through which the heat generated by the starter body 4 can be dissipated through the heat dissipation ports 9; a fan 10 is fixedly sleeved on the inner ring of the right wall of the base 1, through which the starting fan 10 can blow external cold air into the protective shell 3 and dissipate it through the heat dissipation ports 9, thereby increasing the air circulation in the protective shell 3 and avoiding heat accumulation in the protective shell 3; a plurality of bolts 12 are evenly and symmetrically threaded on the top of the top cover 11, and the top cover 11 is fixedly mounted on the top of the base 1 by the plurality of bolts 12, through which the protective shell 3 can be opened conveniently and the starter body 4 in the protective shell 3 can be inspected and repaired. Embodiment 2

[0024] like Figure 1-4 As shown, a housing for a DC starter proposed by the utility model, compared with the first embodiment, is provided with limit grooves 13 on the left and right inner walls of the base 1.
