The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art according to specific circumstances.

Referring to fig. 1 and 2, as shown in the drawings, a badminton ball recovery device for physical education according to an embodiment of the present invention includes an autonomous moving vehicle frame 1, an adjusting bracket 2 disposed on the vehicle frame 1, and a badminton ball collecting basket 3 fixed on the adjusting bracket 2. The carriage 1 can move autonomously on a training field without manual pushing or remote control. The adjusting bracket 2 is formed by a connecting rod and a hinged shaft, and has a specific structure as shown in figure 1, and can realize forward tilting adjustment and backward tilting adjustment. The ball collecting mechanism 5 is arranged at the ball collecting opening of the ball collecting basket 3, and when the adjusting bracket 2 is in a forward tilting adjusting state, the ball collecting mechanism 5 is in sliding contact with the ground, so that the badminton on the ground can be rolled into the ball collecting basket 3. When the adjusting bracket 2 is in a backward tilting adjusting state, the ball collecting basket 3 can fall in the frame 1 to reduce the height of the ball collecting basket, so that the height of the whole device is reduced at a lower position, and the whole device can be flexibly placed in a storehouse when being idle. When the adjusting bracket 2 is in a forward-tilting adjusting state, the ball collecting basket 3 is placed forwards on the front beam of the frame 1, so that the height of the ball collecting basket 3 is reduced, the height of the whole device is reduced at a lower position, and the device is convenient to flexibly move at a low corner and a narrow space when in work.

Further, in the preferred embodiment of the present invention, as shown in fig. 3, the ball collecting mechanism 5 includes a ball collecting tongue plate 51, a ball rolling brush 53 and two shaft brackets 52. Wherein, the left and right sides of the ball-collecting tongue plate 51 are hinged with the left and right side beams 31 of the bottom frame of the frame 1 through damping rotating shafts, and two rotating shaft brackets 52 are respectively fixed on the left and right sides of the ball-collecting tongue plate 51 near the front end tongue opening thereof. The ball rolling brush 53 is rotatably connected between the two rotating shaft frames 52, wherein a micro motor 54 in transmission connection with the ball rolling brush 53 is fixed on one of the rotating shaft frames 52, and the ball rolling brush 53 can be driven to rotate by the driving of the micro motor 54 so as to roll the badminton on the training ground into the ball collecting basket 3 through the ball collecting tongue plate 51.

In some embodiments, as shown in fig. 3, the shaft bracket 52 includes a fixing portion 521 and a rotating portion 522, the rotating portion 522 is rotatably connected to the fixing portion 521 through a damping shaft, and an end of the ball rolling brush 53 is rotatably connected to the fixing portion 521. When the rolling ball brush is used, the height of the rolling ball brush 53 from the ground can be flexibly adjusted by adjusting the angle between the rotating part 522 and the fixing part 521. In order to reduce the resistance of the tongue 51 to scrape on the ground, as shown in fig. 3, the front end mouth of the tongue 51 is further formed with a smooth-bottomed rubber strip 511, and the tongue 51 is provided with a micro pulley 55 at a position close to the front end mouth.

Specifically, as shown in fig. 1, driving wheels 11 are respectively disposed at two corners of the front end of the frame 1, and driven wheels 12 are respectively disposed at two corners of the rear end. The two driving wheels 11 are respectively connected with a driving motor 6, one driving motor 6 is connected with a differential steering engine 7, and a power supply 8 is arranged on a front beam of the frame 1. When the rotation speeds of the two driving wheels 11 are the same, the whole device moves linearly towards the front, and when the rotation speeds are different, the whole device turns towards the side with lower rotation speed to move. Specifically, the rotation speed difference is controlled through a differential steering engine 7, namely, a driving motor which is not connected with the differential steering engine moves at a preset speed and a constant speed, and a driving motor 6 which is connected with the differential steering engine 7 realizes speed change under a control signal of the differential steering engine 7, so that differential steering is realized.

In order to realize the fully intelligent autonomous movement, as shown in fig. 1, a machine vision recognition instrument 4 is arranged on a front beam of the vehicle frame 1, and a plurality of CCD lenses 41 are arranged on a front end face of the machine vision recognition instrument 4. Badminton on the training ground can be intelligently identified through the machine vision identification instrument 4, then a steering signal is given to the differential steering engine 7 through the controller, and the differential steering engine 7 controls the rotation differential of the driving motor, so that the automatic steering of the device is realized. When the shuttlecock is not detected in the front, the differential steering engine 7 obtains a steering signal, controls the driving motor to generate a rotation differential speed to enable the device to steer, and then carries out shuttlecock detection on the ground in other areas through the machine vision recognition instrument 4. When the badminton is detected in the front, the controller does not output a steering signal to the differential steering engine 7, the two driving motors 6 keep rotating at the same speed, and the device moves towards the front along a straight line. Specifically, the content of machine vision recognition is the prior art, and is not described herein. In order to obtain a better front view, in the preferred embodiment of the present invention, the number of the CCD lenses 41 is set to 3.

In conclusion, the badminton ball recovery device for physical education is simple and practical in overall structure, and by adopting the deformable structural design, the overall size of the badminton ball recovery device can be greatly reduced, so that the badminton ball recovery device is convenient to move and use in low corners and narrow spaces. The time wasted due to ball picking in the training process is obviously reduced, and the training efficiency is improved. After the training is completed, the shuttlecocks on the training field can be automatically recovered and picked up through the shuttlecock recovery device, and unnecessary waste of manpower and material resources is reduced.
