DETAILED DESCRIPTION

[0020] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0021] like Figures 1 to 4 As shown, the utility model can be implemented through the following embodiments: an electromagnetic brake for a scooter, comprising a slot disc 1, an armature 2 is installed on the right side of the slot disc 1, a lower friction plate 3, a brake disc 4, an upper friction plate 5 and a cover plate 6 are installed on the right side of the armature 2 in sequence, an external spline 401 is connected to the brake disc 4, a trigger 7 is installed on the left side of the brake disc 4, the trigger 7 is divided into a fixing part 701, a limiting part 702 and a pulling part 703, the trigger 7 is fixed to the slot disc 1 by a screw 8, a mounting slot 101 is opened in the slot disc 1, a spring fixing column 9 is installed on the mounting slot 101, a spring 10 is installed outside the spring fixing column 9, a micro switch 11 is installed on the left side of the slot disc 1, and a contact 1101 is arranged on the micro switch 11.

[0022] The trigger 7 drives the screw 8 to rotate by rotating, and the screw 8 drives the spring fixing column 9 to move, and the spring fixing column 9 drives the armature 2 to move right, so that the lower friction plate 3 on the armature 2 contacts the brake disc 4, and the lower friction plate 3 cooperates with the upper friction plate 5 to clamp the brake disc 4, thereby realizing the deceleration braking of the electromagnetic brake; the micro switch 11 is used to prompt the user whether the mechanical brake part is opened after the trigger 7 is pulled, so that the user can understand the status of the scooter.

[0023] like Figure 2 and Figure 3 As shown, a groove 7011 is provided on the fixing portion 701, and contact portions 7012 are provided on both sides of the groove 7011. The groove 7011 is used for the trigger 7 to avoid the contact 1101 when the trigger 7 is not rotated to prevent the micro switch 11 from being accidentally turned on; the contact portion 7012 is used to touch the contact 1101 after the trigger 7 is rotated to start the micro switch 11.

[0024] like Figures 1 to 4 As shown, a mounting hole 102 is provided on the left end surface of the slot plate 1, a limiting column 12 is arranged in the mounting hole 102, and a corresponding limiting waist hole 7021 is provided on the limiting portion 702. The mounting hole 102 is used to install and fix the limiting column 12, and the limiting column 12 is used to cooperate with the limiting waist hole 7021 to prevent the trigger 7 from rotating too much and causing the trigger 7 to fall off.

[0025] like Figure 2 and Figure 4 As shown, two mounting holes 102 are provided, and one limiting column 12 is provided. The provision of two mounting holes 102 and one limiting column 12 facilitates the change of the installation position of the electromagnetic brake, and is convenient for meeting the needs of people with different needs.

[0026] like Figures 1 to 3As shown, a through hole 7031 is provided on the pull portion 703. The through hole 7031 is provided to reduce the mass of the electromagnetic brake without affecting the overall strength of the trigger 7, thereby saving space in the scooter and achieving lightweighting of the scooter.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, the groove plate 1 is provided with a concave hole 103, the fixing part 701 is provided with a concave hole 2 7013, a steel ball 13 is provided between the concave hole 103 and the concave hole 2 7013, and a fixing hole 7014 is provided on both sides of the concave hole 2 7013. The concave hole 103 and the concave hole 2 7013 cooperate with the steel ball 13, so that when the trigger 7 rotates relative to the groove plate 1, sliding friction is formed to reduce resistance, which is convenient for the manual brake to start quickly; the fixing hole 7014 is used to clamp the steel ball 13 after the trigger 7 rotates, to prevent the steel ball 13 from causing the trigger 7 to rotate or fall off after the sliding friction is formed between the trigger 7 and the groove plate 1; grease can be applied to the fixing hole 7014 to ensure the lubrication of the steel ball 13 and reduce the maintenance of the steel ball 13.

[0028] like Figure 1 and Figure 2 As shown, the micro switch 11 is fixed to the left end surface of the slot plate 1 by means of a second screw 14. The second screw 14 fixes the micro switch 11 to the left end surface of the slot plate 1, which is convenient for replacement of the micro switch 11 after it is damaged, and at the same time makes the micro switch 11 and the trigger 7 on the same plane, reduces the maximum cross-sectional area generated by the electromagnetic brake, and reduces the installation space required for installing the electromagnetic brake.

[0029] The working principle of the utility model is as follows: the user holds the pulling part 703 of the trigger 7 and pulls it, so that the trigger 7 rotates relative to the groove plate 1, and the trigger 7 moves the spring fixing column 9 to the right through the screw 8, so that the armature 2 moves to the right, and the armature 2 that moves to the right drives the lower friction plate 3 to cooperate with the upper friction plate 5 to clamp the brake disc 4, so that the brake disc 4 stops rotating at the external spline 401 that it contacts, locks the rotation of the motor, and completes the braking; after the trigger 7 is restored, the spring fixing column 9 moves to the left, releasing the push on the armature 2, and then releasing the braking state.

[0030] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0031] Although various terms are used more frequently in this article, the possibility of using other terms is not excluded. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
