Description

Technical Field

[0001] The utility model relates to the technical field of starter motors, and in particular to a beach motorcycle starter motor. Background Art

[0002] The motorcycle starter motor is a common mechanical device that plays a vital role in the starting of a motorcycle. The working principle of the motorcycle starter motor is mainly realized through the principle of electromagnetic induction. When the electromagnetic switch is turned on, the current passes through the motor coil, generating a magnetic field, which interacts with the magnetic steel on the center shaft to generate a rotational torque, causing the center shaft to rotate. As the center shaft rotates, the carbon brush contacts the rotating center shaft, transmitting current, causing the entire motor to continue to rotate, thereby starting the motorcycle.

[0003] On the motorcycle starter motor, since the motor terminals are exposed, they are easily exposed to water and other external factors, which can cause the terminals to rust, corrode and be damaged. However, when replacing the terminals, the motor casing needs to be disassembled for replacement, which brings great inconvenience to maintenance personnel. Misdisassembly may also cause damage to other internal components of the motor, causing the entire motor to be scrapped. Utility Model Content

[0022] The utility model provides a beach motorcycle starter motor, comprising a housing 1, a front cover 2 and a rear cover 3, wherein the front cover 2 is arranged at the right end of the housing 1, the rear cover 3 is arranged at the left end of the housing 1, a rotor is arranged in the housing 1, a stator coil is also arranged in the housing 1, and a terminal 4 connected to the stator coil is arranged on the rear cover 3. The above is a well-known technology for personnel in the field, and the specific connection relationship and working principle are not described in detail here. An insulating gasket 5 is provided on the outer ring of the terminal 4, and the insulating gasket 5 is embedded in the rear cover 3, and the terminal 4 is equipped with a fixed structure;

[0023] An insulating pad 6 is fixedly sleeved on the terminal 4;

[0024] The fixing structure includes a slide rail 7 located at the left and right ends of the terminal 4, the slide rail 7 is fixed to the lower wall of the insulating gasket 5, a limit plate 8 is slidably arranged in the slide rail 7, a screw rod 9 is spirally arranged in the limit plate 8, one end of the screw rod 9 passes through the limit plate 8, and the end of the screw rod 9 passes through the limit plate 8 and rotates through a support seat 10, and the support seat 10 is fixed to the lower wall of the insulating gasket 5;

[0025] Rotate the screw rod 9 to move the limit plate 8, move the limit plate 8 to the lower end of the insulating pad 6 and fit it thereto, so as to support the insulating pad 6;

[0026] A circular groove 11 is formed on the lower wall of the insulating gasket 5, and an insulating sealing ring 12 is fixed in the circular groove 11. The overall thickness of the insulating pad 6 and the insulating sealing ring 12 is the same as the thickness of the circular groove 11.

[0027] A turntable 13 is mounted on the screw rod 9 to facilitate the rotation of the screw rod 9;

[0028] At least one locking bolt 14 is spirally penetrated on the turntable 13. The locking bolt 14 is rotated to make the locking bolt 14 abut against the side wall of the support seat 10, so as to fix the turntable 13;

[0029] A plurality of rollers 15 are rotatably embedded on the upper wall of the limiting plate 8 to reduce friction between the limiting plate 8 and the insulating pad 6 and reduce wear.

[0030] In some embodiments of the present application, during installation, the terminal 4 is passed through the insulating gasket 5, so that the insulating pad 6 on the terminal 4 is located in the circular groove 11 and fits with the insulating sealing ring 12. By rotating the screw rod 9, the screw rod 9 is rotated in the limiting plate 8, which can drive the limiting plate 8 to move, so that the limiting plate 8 moves to the lower end of the insulating pad 6, so that the limiting plate 8 is against the lower wall of the insulating pad 6 for support and limitation, and the position of the insulating pad 6 is fixed, thereby achieving the position fixation of the terminal 4 and completing the installation of the terminal 4. When the terminal 4 works normally, the insulating pad 6 on the terminal 4 is located in the circular groove 11, and the overall thickness of the insulating pad 6 and the insulating sealing ring 12 is the same as the thickness of the circular groove 11, so as to prevent the terminal 4 from shaking. The external current is transmitted to the motor coil through the terminal 4. When the terminal 4 is rusted and damaged and needs to be replaced, the screw rod 9 is rotated to drive the limit plate 8 to move away from the insulating pad 6, so that the limit plate 8 is separated from the insulating pad 6, and the terminal 4 is removed, that is, the terminal 4 can be replaced without disassembling the motor, which is very convenient.

[0031] The rotating disk 13 can be fixed by the locking bolts 14 against the side wall of the support seat 10 to prevent the rotating disk 13 from rotating by itself, causing the limit plate 8 to move, thereby affecting the fixing effect. In this case, a pair of locking bolts 14 are used to strengthen the fixing effect of the rotating disk 13;

[0032] During the movement of the limit plate 8, the roller 15 is provided to reduce the friction between the limit plate 8 and the insulating pad 6, changing the sliding connection into a rolling connection, thereby reducing the wear on the limit plate 8 and the insulating pad 6 and extending the service life.

[0033] In some embodiments of the present application, Figure 3As shown, the insulating pad 6 and the terminal 4 are detachably connected, which is convenient for replacing the insulating pad 6. When the insulating pad 6 is severely worn and the terminal 4 can be used normally, only the insulating pad 6 needs to be replaced, and the terminal 4 does not need to be replaced, which saves resources and reduces maintenance costs. The terminal 4 is provided with mounting plates 16 on the left and right sides. The mounting plates 16 are insulating plates. A groove 17 is provided on the upper wall of the mounting plate 16. A groove body 18 matching the groove 17 is provided on the lower wall of the insulating pad 6. During installation, the groove 17 is butted with the groove body 18, and the connection is connected by fixing bolts to fix the insulating pad 6 and the mounting plate 16.

[0034] When replacing the insulating pad 8, rotate the screw rod 9 to make the screw rod 9 rotate in the limit plate 8, drive the limit plate 8 to move, and separate the limit plate 8 from the insulating pad 6. Pull out the terminal 4 from the insulating gasket 5 and remove it. Remove the fixing bolts, separate the insulating pad 6 from the mounting plate 16, and replace it with a new insulating pad 6. This realizes the disassembly of the insulating pad 6, facilitates the replacement of the insulating pad 6, saves resources, and reduces the cost of maintenance.

[0035] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
