Portable tennis ball service all-in-one machine

Abstract

The invention discloses a portable tennis ball service all-in-one machine which can realize functions of picking up tennis balls and cleaning fields. The portable tennis ball service all-in-one machine comprises a chassis module, a tennis ball pick-up module, a field cleaning module and a box body. In the chassis module, a drive wheel is individually driven by two wheels to realize in-situ steering by utilizing the differential speed of the two wheels, thereby reducing the turning radius and improving the working efficiency; and a driven wheel utilizes a shocking-proof suspension frame manner to ensure the contact of time and ground and the stability of operation. The tennis ball pick-up module and the filed cleaning module are mutually independent, a mechanical arm ball holding mechanism in the tennis pick-up module utilizes a five-connecting-rod mechanism with double degrees of freedom so as to effectively realize unfolding and flexing movements, two degrees of freedom are driven by single power, and conversion of degrees of freedom is realized through a press rod mechanism and a locating sleeve in the movement process. A rolling brush in the field cleaning module can move up and down and rotate; in addition, the portable tennis ball service all-in-one machine does not leave from the ground through an undercarriage lifting mechanism when not in cleaning, and acts enough pressure on the ground during brushing so as to realize a cleaning function.

Description

technical field [0001] The invention relates to a portable tennis service all-in-one machine, which belongs to the technical field of mechanical design. Background technique [0002] At present, tennis has become a sport that is both casual and fashionable and has the value of lifelong exercise. However, looking at the tennis equipment supply market at home and abroad, the products provided are still quite monotonous. Except for the necessary equipment for tennis, there has not been much breakthrough and innovation in the supporting service facilities of tennis courts, which mainly rely on intensive human labor. In recent years, the tennis ball picking machine proposed by someone is basically limited to theoretical research, and the produced prototype has poor practical effect, high failure rate, and poor market response. At present, major tennis clubs and gymnasiums have the following outstanding problems to be solved urgently: [0003] (1) Picking up tennis balls is time...

AI Technical Summary

Problems solved by technology

[0003] (1) Picking up tennis balls is time-consuming and laborious: due to the large tennis court, picking up tennis balls scattered in the court is the most troublesome thing for beginners and high-end fitness enthusiasts

In view of this, at present, large fitness clubs provide the service of caddies picking up balls, that is, the exclusive VIP service of "one game per person", but the cost is relatively high, and the beneficiary group is very small

In addition, for tennis amateurs, because of their high rate of conceding balls, they repeatedly go back and forth to pick up balls throughout the court, which reduces the fun and continuity of playing.

[0004] (2) Untimely cleaning and dust removal of the site: Due to the large number of sites and the large area, the maintenance and cleaning of the site is not timely, resulting in indoor dust and inhalable particulate matter suspended in the air for a long time, which has an adverse effect on the health of exercisers

These three types of ball picking methods all rely on pressure to press the ball in, but this pressing method will damage the surface of the ball, and because it needs to rely on static pressure, the breeding required for this type of equipment is relatively heavy, and it is inconvenient to carry and carry

In addition, this kind of equipment still needs to be driven by manpower. Picking up the ball around the field does not fundamentally solve the problem of difficulty in picking up the ball. It only reduces the frequency of players bending over to pick up the ball, and the efficiency of picking up the ball does not improve much.
