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 mid-trigger 7-type vehicle, comprising a slot disc 1, a coil 101 is installed in the slot disc 1, an armature 2, a lower friction plate 3, a brake disc 4, an upper friction plate 5 and a cover plate 6 are arranged in sequence on the left side of the slot disc 1, a through hole 102 is opened in the slot disc 1, a trigger 7 is installed between the cover plate 6 and the armature 2, an external spline 401 is installed in the brake disc 4, a mounting hole 103 is opened in the slot disc 1, a spring 8 is installed in the mounting hole 103, a mounting portion 104 is opened on the side of the slot disc 1, a micro switch 9 is installed on the mounting portion 104, a contact 901 is arranged on the micro switch 9, and a trigger pin 902 is arranged next to the contact 901.

[0022] The opening of the through hole 102 eliminates the original trigger 7 and spring fixing column 903 structure, making it easier for the motor spindle to extend into the electromagnetic brake; the trigger 7 is installed between the cover plate 6 and the armature 2, giving the motor spindle space to extend into the electromagnetic brake without affecting the manual brake function; a spring 8 is installed in the mounting hole 103 to replace the function of the spring fixing column 903, and to lift the armature 2 after the trigger 7 is pulled to complete the braking; the micro switch 9 is used to touch the contact 901 through the trigger pin 902 after the trigger 7 is pulled, thereby prompting the user that the manual brake is in the on state.

[0023] like Figure 2 As shown, the trigger pin 902 and the micro switch 9 are connected via a fixing column 903. The fixing column 903 is used to fix the trigger pin 902 on the micro switch 9, which is convenient for installation, removal and replacement of the trigger pin 902. Compared with directly welding the trigger pin 902 on the micro switch 9, the fixing column 903 connects the trigger pin 902 with the micro switch 9, which is easier to produce and has lower repair costs after damage.

[0024] like Figure 1 , Figure 2and Figure 4 As shown, the trigger 7 is provided with a fixing portion 701, and a pin 7011 is installed on the fixing portion 701, and the pin 7011 contacts the trigger pin 902. The trigger 7 is provided with a pin 7011 through the fixing portion 701, and the pin 7011 contacts the trigger pin 902. This arrangement facilitates that when the trigger 7 is pulled, the pin 7011 pushes the trigger pin 902 under the drive of the trigger 7, so that the trigger pin 902 is close to the micro switch 9, and squeezes and touches to achieve the purpose of activating the micro switch 9.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, a guide post 10 is provided between the cover plate 6 and the slot plate 1, and a limit slot 702 is provided on the trigger 7, and the guide post 10 runs through the limit slot 702. The guide post 10 is used to separate the cover plate 6 and the slot plate 1 and guide the movement direction of the armature 2. The guide post 10 runs through the limit slot 702, so that after the trigger 7 is pulled, the trigger 7 is prevented from excessively rotating, causing the connection between the trigger 7 and the electromagnetic brake to fail, so that the trigger 7 is separated from the electromagnetic brake.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, a steel ball groove 703 is provided on the trigger 7, and a steel ball 7031 is installed in the steel ball groove 703. The setting of the steel ball 7031 replaces the contact between the trigger 7 and the cover plate 6 and the armature 2, so that the steel ball 7031 contacts the cover plate 6 and the armature 2, and the rolling friction of the steel ball replaces the sliding friction, thereby reducing the resistance generated when the trigger 7 is pulled, and reducing the response time of the manual brake. The steel ball groove 703 is used to limit the steel ball 7031 to prevent the steel ball 7031 from accidentally detaching during the pulling process of the trigger 7.

[0027] like Figure 1 and Figure 2 As shown, a second mounting hole 105 is provided in the slot plate 1, a second spring 11 is installed in the second mounting hole 105, and a second steel ball 1101 is installed on the second spring 11. The second steel ball 1101 is used to pass through the armature 2 and then abut against the trigger 7. The second spring 11 provides a thrust to push the trigger 7, so that the trigger 7 contacts the cover plate 6, and provides space for the armature 2 to move. The second mounting hole 105 is used to provide space for installing the second spring 11, and at the same time limit the movement of the second spring 11 to prevent the second spring 11 from radially jumping.

[0028] like Figure 4 As shown, the trigger 7 is provided with a force groove 704, and the force groove 704 contacts the second steel ball 1101. The force groove 704 is used to accommodate the second steel ball 1101 to prevent the trigger 7 from sliding and causing the brake to open after vibration occurs. At the same time, the force groove 704 increases the force area between the second steel ball 1101 and the trigger 7, making it easier to push the trigger 7.

[0029] 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.

[0030] 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.
