[0020] The present utility model will be further described below in conjunction with the drawings and preferred embodiments.

[0021] Embodiment 1

[0022] See Figures 1 to 4As shown in the figure, a light-emitting baby carriage tire involved in this embodiment includes a light-conducting tire body 1. At least three mounting counterbores 2 with equal adjacent intervals and extending radially are circumferentially arranged on the inner tire surface of the tire body 1. An annular groove 3 is provided on the pore wall of the mounting counterbore 2, and a PCB main board 4 is embedded in the annular groove 3. A microswitch 5, a lamp bead 6, and a battery 7 are electrically connected to the PCB main board 4. The microswitch 5 is arranged on one side of the PCB main board 4 facing away from the orifice of the mounting counterbore 2. A driving hole 8 that communicates with the outside at one end and the mounting counterbore at the other end is opened on the tire body 1. A driving column 9 is slidably connected in the driving hole 8. One end of the driving column 9 has a driven convex part 91 close to the contact rod of the microswitch, and the other end has a driving convex part 92 protruding from the outer tire surface of the tire body. An elastic connecting ring 10 is provided between the driving column 9 and the tire body 1.

[0023] Further, the lamp bead 6 is arranged on one side of the PCB main board 4 facing away from the orifice of the mounting counterbore 2; the battery 7 is arranged on one side of the PCB main board 4 facing the orifice of the mounting counterbore 2.

[0024] Further, both the driven convex part 91 and the driving convex part 92 are spherical.

[0026] Further, the tire body 1, the driving column 9, and the elastic connecting ring 10 are all made of transparent soft rubber material.

[0027] In this embodiment, first, the tire is installed on the wheel hub to form a baby carriage wheel. Then, when the wheel rolls, the ground will contact and squeeze the driving convex part 92. The driving column 9 moves axially along the driving hole 8, and the elastic connecting ring 10 deforms. The driven convex part 91 further extends into the mounting counterbore 2, touching the contact rod on the microswitch 5, until the circuit is turned on, and the lamp bead 6 is lit. Through the light conduction of the tire, the tire realizes self-luminescence.
