Description

Technical Field

[0001] The present invention relates to the field of table tennis picking-up equipment, and specifically refers to a table tennis electronic picker. Background Art

[0002] In table tennis sports, whether in professional training venues or amateur entertainment places, the task of picking up table tennis balls has always been time-consuming and laborious. Currently, the common ways of picking up table tennis balls mainly include the following:

[0003] 1. Manual picking up: This is the most traditional way. Athletes or staff bend down to pick up table tennis balls one by one. This way is not only inefficient, but also bending down for a long time will cause a great burden on the human waist and is easy to cause waist diseases. In addition, for large-scale table tennis venues, manual picking up requires a lot of time and energy.

[0004] 2. Picking up assisted by simple tools: Such as using tools like brooms and dustpans for picking up. Although this way is slightly more efficient than directly picking up by hand, there are still problems such as inconvenient operation and easy damage to table tennis balls. For example, the broom may scratch the table tennis balls during the cleaning process, affecting the service life of the table tennis balls.

[0005] Defects of the Prior Art

[0006] 1. Low efficiency: Whether it is manual picking up or picking up assisted by simple tools, it is impossible to quickly collect a large number of table tennis balls. In professional training venues, due to the high training intensity and the wide scattering range of table tennis balls, the traditional picking-up methods often take a long time to complete the picking-up work, seriously affecting the training efficiency.

[0007] 2. High labor intensity: Manual picking up requires continuous bending down and standing up, causing great pressure on the human waist and legs. Long-term repetitive movements are easy to cause fatigue and muscle damage, increasing the labor intensity of athletes and staff.

[0008] 3. Easy to damage table tennis balls: When using tools like brooms for picking up, it is easy to scratch and collide with table tennis balls, damaging the surface of the table tennis balls and reducing the quality and service life of the table tennis balls.

[0009] 4. Lack of intelligence: Most of the existing table tennis picking-up methods rely on manual operation and lack intelligent design. It is impossible to realize functions such as automatic picking up, classification, and counting, and cannot meet the requirements of modern stadiums for high efficiency and convenience. Summary of the Invention

[0010] The present invention aims to solve the above technical problems and provides a table tennis electronic picker.

[0011] To solve the above technical problems, the technical solution provided by the present invention is: a table tennis electronic pickup device, which includes a moving mechanism, a collecting mechanism and two groups of baffle mechanisms.

[0012] The moving mechanism includes a bottom plate and a housing. The bottom plate and the housing are assembled together to form a cavity for installing the device. The bottom plate is provided with a set of driving wheels and a universal wheel; the driving wheels provide the power for forward movement, and the universal wheel is convenient for adjusting the direction, so that the pickup device can move flexibly within the table tennis court.

[0013] The collecting mechanism includes rollers and connecting rods arranged on both sides of the rollers. The rollers are rotatably connected to the connecting rods, and the other ends of the connecting rods are arranged in the cavity. The rollers are formed into an olive-shaped structure by a plurality of arc-shaped elastic rods. Rotating joints and connecting heads are provided at both ends of the rollers. The rotating joints and the connecting heads are rotatably connected, and the connecting heads are threadedly connected to the connecting rods. There are gaps between adjacent elastic rods. The distance of the middle gap is greater than the diameter of one table tennis ball and less than the diameter of two table tennis balls, and the gaps on both sides gradually decrease. This structural design enables the table tennis balls to smoothly enter the inside of the rollers, while preventing the table tennis balls from falling from both sides of the rollers.

[0014] The two groups of baffle mechanisms are symmetrically arranged and include a rotating shaft and a baffle. The baffle is fixedly connected to the rotating shaft, and the rotating shaft is rotatably connected to the connecting rod. The baffle is made of an elastic material in an arc shape, a straight rod shape or a bent shape, and can be selected according to actual needs. The function of the baffle is to guide the table tennis balls to the rollers during the movement of the pickup device, thereby improving the pickup efficiency.

[0015] In addition, a table tennis electronic pickup device proposed by the present invention as described above may also have the following additional technical features:

[0016] A controller and a blower box are arranged in the cavity. A blower is arranged in the blower box. A ventilation port communicating with the cavity is arranged on one side of the housing, and the air flow direction of the blower is from the ventilation port towards the inside of the cavity. The function of the blower is to generate an air flow to blow the table tennis balls towards the rollers, further improving the pickup efficiency. A filter screen matching the ventilation port is arranged inside the housing to prevent sundries from entering the cavity and affecting the normal operation of the device.

[0017] The connecting rods are respectively arranged on one side of the ventilation port. A wind baffle is arranged on the side of the connecting rod away from the rollers. One end of the wind baffle is fixedly connected to the connecting rod, and the other end is not in contact with the connecting rod. The function of the wind baffle is to guide the air flow, making the air flow more concentratedly blown towards the rollers, thereby improving the efficiency of the blower.

[0018] Collision sensors are arranged in the circumferential direction of the housing. The collision sensors can detect the distance between the pickup device and surrounding objects. When the pickup device approaches an obstacle, the collision sensors will send out signals, and the controller controls the driving wheels and the universal wheel to adjust the direction to avoid the pickup device from colliding with the obstacle.

[0019] The advantages of the present invention compared with the prior art are as follows:

Compared with the traditional manual picking-up method, the picker of the present invention can collect a large number of table tennis balls in a short time, saving time and labor costs.

[0022] The rollers in the collecting mechanism are surrounded by multiple arc-shaped elastic rods to form an olive-shaped structure, and there are gaps between adjacent two elastic rods. This design enables the table tennis balls to smoothly enter the inside of the rollers, and at the same time prevents the table tennis balls from falling from both sides of the rollers. In addition, the airflow generated by the fan can blow the table tennis balls towards the rollers, further improving the picking-up efficiency.

[0023] The baffle in the baffle mechanism is made of elastic material in an arc shape, a straight rod shape or a bent shape, and can be selected according to actual needs. The function of the baffle is to guide the table tennis balls to the rollers during the movement of the picker, improving the picking-up efficiency.

[0024] 2. Reduce the labor intensity

[0025] The table tennis electronic picker of the present invention can automatically move in the table tennis court and pick up table tennis balls, without the need for manual bending to pick up each table tennis ball one by one, greatly reducing the labor intensity. Athletes and staff can invest more time and energy in training and work, improving work efficiency.

[0026] The moving mechanism of the picker adopts a design combining driving wheels and universal wheels, enabling the picker to move flexibly in the table tennis court, with convenient operation and without consuming too much physical strength.

[0027] 3. Protect the table tennis balls

[0028] The rollers in the collecting mechanism are composed of arc-shaped elastic rods. This design can avoid scratching and colliding with the table tennis balls, protect the surface of the table tennis balls, and extend the service life of the table tennis balls.

[0029] The airflow generated by the fan blows the table tennis balls towards the rollers, avoiding the damage that may be caused to the table tennis balls when using tools such as brooms for picking up.

[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0041] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; for those of ordinary skill in the art, the specific meaning of the above terms in the present invention can be understood according to specific circumstances.

[0042] Working principle of the present invention:

[0043] The moving mechanism is composed of a bottom plate and a housing. The driving wheels on the bottom plate provide the power for forward movement, and the universal wheels facilitate direction adjustment. The driving wheels can be driven by a motor, and the motor is connected to a controller. The controller can control the rotation speed and direction of the motor according to a preset program, thereby controlling the moving speed and direction of the picker; the anti-collision sensor can detect the distance between the picker and surrounding objects. When the picker approaches an obstacle, the anti-collision sensor will send a signal. After receiving the signal, the controller will control the driving wheels and universal wheels to adjust the direction to avoid the picker colliding with the obstacle. The anti-collision sensor can adopt various types of sensors such as ultrasonic sensors and infrared sensors, and the specific type of sensor can be selected according to actual needs;

[0044] The rollers in the collection mechanism are formed into an olive-shaped structure by a plurality of arc-shaped elastic rods, and there are gaps between adjacent elastic rods. When the picker moves in the table tennis court, the table tennis balls will be guided to the rollers by the baffle. Since the rollers are rotatably connected to the connecting rods, when the table tennis balls come into contact with the rollers, the rollers will be driven to rotate. At the same time, the airflow generated by the fan blows the table tennis balls towards the rollers, making it easier for the table tennis balls to enter the inside of the rollers. The table tennis balls that enter the inside of the rollers will be stuck by the elastic rods and will not fall from both sides of the rollers. When the number of table tennis balls in the rollers reaches a certain level, the rollers can be disassembled to pour out the table tennis balls.

[0045] The filter screen inside the housing can prevent sundries from entering the cavity and affecting the normal operation of the equipment. The filter screen can be cleaned or replaced regularly to ensure the normal operation of the equipment;

[0046] The baffle mechanism is composed of a rotating shaft and a baffle. The baffle is fixedly connected to the rotating shaft, and the rotating shaft is rotatably connected to the connecting rod. When the picker moves in the table tennis court, the baffle will rotate as the connecting rod moves. The function of the baffle is to guide the table tennis balls to the rollers to improve the picking efficiency. The baffle is made of an arc-shaped, straight rod-shaped or bent elastic material, which can be selected according to actual needs. The elastic material baffle can deform when it comes into contact with the table tennis ball to avoid damaging the table tennis ball. Specific implementation method:

[0048] Assembly method:

[0049] First, assemble the base plate and the outer shell together to form a cavity for installing the device. Install the driving wheel and the universal wheel on the base plate, and connect the motor to the driving wheel; the base plate and the outer shell can be made of high-strength plastic or aluminum alloy materials.

[0050] Then, thread-connect the roller in the collection mechanism to the connecting rod through the connector. The roller can be made of elastic materials such as rubber or silica gel, and has good elasticity and wear resistance. The connecting rod can be made of stainless steel. Install the connecting rod in the cavity, and install the fan box at a suitable position in the cavity. Open a ventilation port on one side of the outer shell, and install a filter screen at the ventilation port. The fan can be a small DC fan, and the filter screen can be made of materials such as stainless steel wire mesh or nylon mesh.

[0051] Next, rotatably connect the rotating shaft in the baffle mechanism to the connecting rod, and fixedly connect the baffle to the rotating shaft. Select a baffle with a suitable shape according to actual needs. The baffle can be made of elastic materials such as rubber, silica gel or plastic, and has good elasticity and wear resistance. The rotating shaft can be made of stainless steel.

[0052] Finally, install the anti-collision sensor in the circumferential direction of the outer shell, and connect the anti-collision sensor to the controller. Install the controller in the cavity, and connect the controller to components such as the motor, the fan, and the anti-collision sensor. Various types of sensors such as ultrasonic sensors and infrared sensors can be used, and the specific type of sensor can be selected according to actual needs.

[0053] Operation method: Place the picker in the table tennis court, press the start button, and the picker starts to move automatically and pick up table tennis balls. During the picking process, the moving speed and direction of the picker can be adjusted according to actual needs.

[0054] When the number of table tennis balls in the picker reaches a certain level, the roller can be disassembled to pour out the table tennis balls. Then reinstall the roller on the connecting rod and continue the picking work.

[0055] During use, if the picker approaches an obstacle, the anti-collision sensor will send a signal, and the controller will control the driving wheel and the universal wheel to adjust the direction to avoid the picker from colliding with the obstacle.

[0056] The above describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural manners and embodiments without creative efforts, they shall fall within the protection scope of the present invention.
