[0017] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] In this application, the telescopic cylinder 8, controller 16, and speed sensor are purchased directly from the market according to specific models and then matched and installed. A micro motor is installed inside the vehicle body 1, and the micro motor is controlled by the controller 16 to drive the drive shaft 3 to rotate, thereby driving the drive wheel 4 to rotate, thus moving the entire ball cart.

[0019] In this application, the speed of the golf cart is typically set to 10-15 km / h. The adjustment of the extension distance of the telescopic cylinder 8 in this application can adjust the friction between the first friction wheel 14 and the second friction wheel 15 and the ground, increasing friction through compressive stress. As the telescopic cylinder 8 extends downwards, the fixed shaft 9 also descends, causing the arc-shaped rod 11 to rotate on the fixed shaft 9 via the movable sleeve 10. This increases the distance between the first friction wheel 14 and the second friction wheel 15, simultaneously enhancing their compressive stress and friction with the ground.

[0020] See Figure 1 , Figure 2 and Figure 3 The diagram shows an automatic downhill deceleration device for a golf cart, comprising a cart body 1, a front wheel 2 connected to the front end of the cart body 1, a drive shaft 3 at the rear end of the cart body 1, drive wheels 4 mounted at both ends of the drive shaft 3, a vertical column 5 mounted on the cart body 1, a connecting rod 6 fixed to the end of the column 5, and a handle 7 mounted to the end of the connecting rod 6; a deceleration assembly is mounted in the middle of the bottom surface of the cart body 1; the deceleration assembly includes a telescopic cylinder 8, a fixed shaft 9, a movable sleeve 10, an arc rod 11, a universal bearing seat 12, a bracket 13, a first friction wheel 14, and a second friction wheel 15; the upper end of the telescopic cylinder 8 is installed inside the cart body 1, and the lower end of the telescopic cylinder 8 is connected to the fixed shaft 9, the movable sleeve 10 is sequentially fitted on the fixed shaft 9, one side of the movable sleeve 10 is connected to one end of the arc rod 11, the other end of the arc rod 11 is connected to the universal bearing seat 12, the universal bearing seat 12 is mounted on the upper end of the bracket 13, and the first friction wheel 14 and the second friction wheel 15 are both mounted on the bracket 13.

[0021] A speed sensor is installed on the drive shaft 3, and the speed sensor is electrically connected to the controller 16, which is mounted on the handle 7. One end of the controller 16 is electrically connected to the telescopic cylinder 8. The arc-shaped rods 11 can all be rotatably connected via the movable sleeve 10. The first friction wheel 14 and the second friction wheel 15 are arranged diagonally along the axis of the fixed shaft 9. A first binding bracket 19 is installed on the column 5. A second binding bracket 20 is installed on the vehicle body 1 near the front wheel 2. An auxiliary component is also provided at the rear of the vehicle body 1, located in the middle of one side of the drive shaft 3. The auxiliary component includes an auxiliary rod 17 and a guide wheel 18. One end of the auxiliary rod 17 is hinged to the vehicle body 1, and the other end of the auxiliary rod 17 is connected to the auxiliary wheel 18, which is located between the drive wheels 4.

[0022] The working principle of the automatic downhill deceleration device for this golf cart is as follows:

[0023] First, when the golf cart is traveling downhill, its overall speed increases due to its own weight and driving force. The speed sensor transmits the rotation speed signal of the drive shaft 3 to the controller 16 in a timely manner. The controller 16 compares the speed signal with the preset speed signal. If the speed exceeds the preset data signal, the controller 16 will control the deceleration assembly to operate. Specifically, it controls the extension cylinder 8 to extend, so that the fixed shaft 9 pushes downward, forcing the first friction wheel 14 and the second friction wheel 15 to roll downward into contact with the ground. This increases the overall friction and reduces the speed of the golf cart. At the same time, the diagonal arrangement of the first friction wheel 14 and the second friction wheel 15 in the deceleration assembly can provide good auxiliary support, prevent the golf cart from tipping over, and improve the overall driving stability.

[0024] Compared with traditional automatic downhill deceleration devices, this application has the following advantages: an auxiliary deceleration device is added to the original normal braking device of the golf cart, which plays an auxiliary control role in the process of going uphill and downhill. It does not keep the golf cart stationary on the slope, but maintains a certain speed and travels at a constant speed, so as to achieve the same driving as on a flat road, thereby improving the overall driving safety of the golf cart.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
