detailed description

1 to 3, a radio frequency identification system capable of self-adapting the size change of a bicycle wheel, comprising a radio frequency tag 2 and a radio frequency identification module 3 disposed on the lock pile, the radio frequency tag 2 being disposed on the bicycle wheel 1 The end of the axle 11 is. Specifically, the radio frequency tag 2 is an RFID tag, the RFID tag is encapsulated in an ABS plastic case, the ABS plastic case is raindrop-shaped, and the appearance is beautiful and waterproof and dustproof; the ABS plastic case is provided with a mounting hole, and the axle 11 passes through the mounting hole and passes through The nut securely attaches the ABS plastic case to the end of the axle 11. The RFID module 3 is an RFID identification module.

The lock pile includes a lock rocker 20, and the lower end portion of the lock rocker 20 is rotatably connected with the lock pile. The lock rocker 20 can swing in a vertical plane, and the upper end of the lock rocker 20 is locked to the bicycle wheel 1 The front end of the radio frequency identification module 3 is disposed on the lock rocker 20, and the center of the radio frequency identification module 3 is located above and behind the center of rotation of the lock rocker 20.

The radio frequency tag 2 and the radio frequency identification module 3 in the radio frequency identification system of the present invention can perform adaptive adaptation. The radio frequency tag 2 is disposed on the axle 11 of the bicycle wheel 1. The larger the size of the bicycle wheel 1, the higher the position of the radio frequency tag 2, the larger the size of the bicycle wheel 1 locked by the peg, pushing the locking rocker 20 forward The greater the amplitude of the swing. Since the center of the radio frequency identification module 3 is located at the upper rear of the center of rotation of the lock rocker 20, the center of the radio frequency identification module 3 gradually moves upward during the forward swing of the lock rocker 20. Therefore, when the size of the bicycle wheel 1 locked by the lock pile is gradually increased, the position of the radio frequency tag 2 is gradually increased, the swing amplitude of the lock rocker 20 is gradually increased, and the center of the radio frequency identification module 3 is gradually increased. Locking the different swinging amplitudes of the bicycle wheel 1 of different sizes corresponding to the locking rocker 20 realizes the adaptive adjustment of the spatial adaptation distance of the radio frequency tag 2 and the radio frequency identification module 3, which greatly increases the adaptability of the radio frequency identification system. This solves the drawback that the existing RFID system is difficult to apply to bicycle wheels 1 of different sizes.

The invention relates to the installation of the radio frequency tag 2 and the radio frequency identification module 3, and to the relative positional change between the radio frequency tag 2 and the radio frequency identification module 3 in order to accommodate different sizes of the bicycle wheel 1.

The two ends of the curved portion 22 are respectively connected with a first swinging portion 23 and a second swinging portion 21, and the first swinging portion 23 is rotatably connected to the base 30 of the lock pile. The end of the second swinging portion 21 is provided with a locker 4 for locking the bicycle wheel 1. The radio frequency identification module 3 is placed at the curved portion 22 such that the radio frequency identification module 3 is close to the position of the axle 11 of the bicycle wheel 1. At the same time, the rear end portion of the parking slot 31 is provided with a limiting block 32. The limiting block 32 is rotatably connected to the rear end of the parking slot 31, and the bicycle wheel 1 can be pushed into the parking slot 31 via the limiting block 32. The block 32 abuts against the rear end portion of the bicycle wheel 1 to achieve stable parking of the bicycle wheel 1 in the parking slot 31. When the size of the bicycle wheel 1 becomes larger, under the positioning restriction of the limiting block 32, the rear end portion of the bicycle wheel 1 is substantially maintained in position, the front end portion of the bicycle wheel 1 gradually protrudes forward, and the position of the axle 11 is constantly inclined. Moving upwards; the swinging amplitude of the locking rocker 20 is gradually increased, and the RFID module 3 is also continuously moved obliquely upward to complete the adaptation of the RFID module 3 and the RF tag 2.

Preferably, the front end portion of the parking groove 31 is provided with a female bayonet laterally, and the concave snap does not hinder the bicycle wheel 1 having a large size from protruding forward. When the bicycle wheel 1 is pushed into the parking slot 31, the concave bayonet can serve as an auxiliary fixing of the bicycle wheel 1, so that the bicycle wheel 1 is completely parked according to the designed position, thereby achieving the radio frequency identification module 3 and the radio frequency tag. 2 stable adaptation.

Preferably, the bicycle wheel 1 can be 14 inches, 16 inches, 18 inches, 20 inches, 22 inches, 24 inches, 26 inches and 28 inches, and basically meets various sizes of bicycles on the market.

Preferably, the size of the bicycle wheel 1 is 14 inches and the bicycle wheel 1 is locked in the parking slot 31, the limiting block 32 abuts the rear end portion of the 14 inch bicycle wheel 1, and the concave bayonet abuts at 14 The front end of the bicycle wheel 1 is at this time, the connection between the center of the radio frequency tag 2 and the center of the radio frequency identification module 3 is perpendicular to the bicycle wheel 1; the angle between the first swinging portion 23 and the horizontal plane is 50 to 55°, The angle between the first swinging portion 23 and the second swinging portion 21 is 50 to 55°. When the bicycle wheel 1 is the smallest 14 inches, the locking rocker 20 swings to the center of the radio frequency identification module 3 and is located on the same horizontal line as the center of the radio frequency tag 2, so that the radio frequency identification module 3 and the radio frequency tag 2 are perfectly matched. In this embodiment, the angle between the first swinging portion 23 and the horizontal plane is 53°, and the angle between the first swinging portion 23 and the second swinging portion 21 is 52°, which is a better design of the locking rocker 20. value. When the bicycle wheel 1 is the largest 28 inches, as shown in FIG. 3, the angle between the first swinging portion 23 and the horizontal plane is 67, and the radio frequency identification module 3 is still pointed to the axle 11 and is close to the axle 11. The bicycle wheel 1 changes from small to large, and the distance between the radio frequency identification module 3 and the radio frequency tag 2 changes little, which is far less than the height of the radio frequency tag 2 relative to the radio frequency identification module 3 when the radio frequency identification module 3 is in a fixed installation state. The adaptation of the radio frequency identification module 3 to the radio frequency tag 2 is well satisfied.
