Technical Field

The invention discloses a table tennis serving mechanism with adjustable angle force, and particularly relates to the structural design of the table tennis serving mechanism with adjustable angle force.

Background

The table tennis serving machine can enable a user to practice specific actions so as to achieve a good training effect. Because the rotation angle and the strength of the table tennis ball change to generate different effects such as downward rotation, upward rotation, left-right lateral rotation and the like, in order to simulate the effect of a real person playing the table tennis ball, the angle and the strength of the table tennis ball serving machine when the table tennis ball is launched need to be adjusted.

Disclosure of Invention

In order to solve the defects, the invention discloses a table tennis serving mechanism with adjustable angle and force.

In order to achieve the purpose, the invention adopts the following technical scheme:

the invention discloses a table tennis serving mechanism with adjustable angle and force, which is characterized in that: comprises a service motor, a service roller, an adjusting column, a bearing, a gear structure, a shell, a battery pack, a control panel and a rotating motor; the service motor and the service roller are fixed at a ball outlet of the adjusting column through a structural part; the service roller is made of rubber and is connected with a motor shaft of a service motor through a coupler, and the ball body obtains a forward initial speed through friction force; the adjusting column is arranged in the bearing sleeve in an interference fit mode, a gear tooth structure is meshed with the gear structure at the ball inlet at the tail end, and a cylindrical structure penetrates through the adjusting column to serve as a ball path; the gear structure is used for transmission and is connected with a motor shaft of the rotating motor in an interference fit mode; the battery pack, the control panel and the rotating motor are all fixed in the inner cavity of the shell through respective structural parts; the battery pack, the ball serving motor and the rotating motor are connected with the controller through the rows.

In any of the above schemes, preferably, the service motor and the rotating motor are both stepping motors, and there are two service motors and one rotating motor.

In any of the above embodiments, preferably, the housing has a support frame in front of the bearing, and the support frame has a support roller thereon for supporting the adjustment column.

In any of the above schemes, preferably, the cylindrical ball path for ball entering is reserved at the rear end of the shell, the diameter of the cylindrical ball path is the same as that of the reserved ball path of the adjusting column, and the inner side wall of the ball path is flat after the two ball paths are in butt joint.

Preferably, in any of the above schemes, the adjusting column is internally provided with a through hole for arranging the flat cable, and the diameter of a reserved ball path of the adjusting column is smaller than the distance between the ball serving rollers and larger than the diameter of a table tennis ball.
