[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Embodiment 1

[0022] Please refer to Figures 1-4, the present utility model provides a technical solution: an electric golf cart parking brake device, which includes a switch control system 1, an electric push rod motor assembly 2 and a parking brake mechanical system assembly 3. The electric push rod motor assembly 2 includes an electric push rod 21, and the parking brake mechanical system assembly 3 includes a parking brake wire kit 31 and a brake caliper assembly 32. The A end of the electric push rod 21 is fixedly connected to the parking brake wire kit 31, and the B end of the parking brake wire kit 31 is fixedly connected to the brake caliper assembly 32. The switch control system 1 includes a boat-shaped two-position switch 11, an electric push rod wire harness 12, a time relay base 14 and a time relay 13. The time relay 13 is fixedly installed on the upper end of the time relay base 14 through a hardware connecting plate. The electric push rod wire harness 12 and the boat-shaped two-position switch 11 are connected to each other through wires. The electric push rod 21 is connected to the plug of the switch control system 1 through a wire.

[0023] Assembly process: The electric push rod 21 can be fixedly installed on the electric golf cart accelerator box through bolts. Then, the A end of the electric push rod 21 is fixedly connected to the parking brake wire kit 31 through bolts, and the connection position of the B end of the parking brake wire kit 31 and the brake caliper assembly 32 is fixedly connected, so that the tightness of the parking brake wire can be adjusted at the connection of the electric push rod 21;

[0024] The time relay 13 is fixedly installed on the upper end of the time relay base 14 through a hardware connecting plate. Then, through wires, the electric push rod wire harness 12 and the boat-shaped two-position switch 11 are connected to each other. Finally, through wires, the electric push rod 21 and the plug of the switch control system 1 are connected to each other, thus completing the installation of the device;

[0025] Among them, the number of pins of the boat-shaped two-position switch 11 is six, and these six pins are connected to a 12V / 10A power supply through wires. The working time of the time relay 13 is 8 seconds;

[0026] Working principle: After the boat-shaped two-position switch 11 is connected to a 12V power supply, when the button of the boat-shaped two-position switch 11 is turned on, the 12V power supply can reach the 10A protection fuse, and then be transmitted to the time relay 13 to start its working time, which is 8 seconds. The 12V power supply is transmitted to the electric push rod 21, and through the principle of telescopic pull rod retraction, the parking brake wire is tightened to achieve the parking function; when it is necessary to release the parking brake, by closing the button of the boat-shaped two-position switch 11, a reverse current can be output to the time relay 13, which can drive the electric push rod 21 to release the tightened effect, so that the parking brake wire can be retracted and extended freely;

[0027] In addition, this device can be installed and fixed on golf carts of various models. Because the installation of the electric push rod 21 device is simple and practical, it can be selected and installed by users on a variety of golf cart models.
