TWI797041B - Expanded collecting mechanism for ball picker - Google Patents

Abstract

The present invention relates to an expanded collecting mechanism for a ball picker, which mainly has a ball picking device and a ball collecting device fitted on both sides of the ball picking device. The ball collecting device further has a power source, a coupling seat, and a guide rod pivoted on the coupling seat. The power source of the ball collecting device can drive a screw to move the coupling seat, so that the guide rod on the coupling seat can co-move a ball leading flank to stretch or collapse. Accordingly, the stretched ball leading flank can significantly expand a ball collecting range so as further to increase area for collection of exercise balls, save much time for ball collection and promote the speed and efficacy of picking balls.

Description

Extended Ball Collection Mechanism of Ball Picker

The present invention relates to an extended ball-collecting mechanism of a ball-picking machine, especially a ball-picking mechanism capable of expanding the range of ball-collecting.

By the way, with the improvement of living standards, people pay more and more attention to exercising through sports, and various ball games, such as tennis, golf, baseball, etc., can not only achieve the effect of leisure and fitness, but also can The people who engage in the ball games can relax physically and mentally and relieve stress effectively, so that more and more people love to engage in various ball games.

As far as tennis training is concerned, it is a sport that is very suitable for men, women, old and young. During tennis training, due to the desire to emphasize training efficiency and avoid wasting time on picking up tennis balls, everyone A lot of tennis balls will be used for training, and after the training is over, the tennis balls will be manually picked up one by one and collected.

However, the work of picking up balls is a heavy physical labor. Tennis players consume a lot of physical energy after training. It is time-consuming and difficult to pick up tennis balls all over the floor with a tired body. It will consume a lot of physical strength and energy of athletes, and the commonly used tools for picking up balls generally use tennis rackets and brooms, but because tennis balls are small in size and easy to roll, they can be swept to an area by the broom, or tennis balls are picked up one by one by the tennis racket. The collection mode is not effective; in addition, there is also a vertical manual ball picker, which is also not efficient in picking up balls and takes a lot of time.

Because of this, the applicant has developed announcement No. I655023 "Smart Tennis Ball Picking System and Ball Picking Method" and Announcement No. I729499 "Smart Ball Picking System and Ball Picking Method" to address the above problems and deficiencies. Through the above ball picking system , using image detection to automatically search for the position of the ball, and through the straight or horizontal movement of the mecanum wheel, control the body to move to the position of the searched ball, so as to pick up and collect the ball, so that the user can use it after training the ball , no need to spend time and physical strength to pick up and collect the balls one by one, which can greatly save time and physical strength, and increase the efficiency of ball exercise training. In addition, using the mecanum wheel to move the body can be more quickly in one Comprehensive collection of spheres within a predetermined area.

However, the inventor observed that the sphere has an irregular rolling range due to different factors. The smart ball picking machine that runs in a straight line needs to go back and forth many times to pick up and collect the scattered spheres; Years of rich design, development and actual production experience in this related industry, research and improvement on the existing structure and defects, provide an extended ball collection mechanism for the ball picker, in order to achieve better practical value.
