[0017] The following through specific concrete example explains the embodiment of the utility model, and the person skilled in the art can easily understand other advantages and effects of the utility model from the content disclosed in the specification. The utility model can also be implemented or applied by another different specific embodiment, and each detail in the specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the utility model. It should be noted that the following examples and features in the examples can be combined with each other without conflict.

[0018] It should be noted that the drawings provided in the following examples only illustrate the basic concept of the utility model in a schematic manner, and only the components related to the utility model are shown in the drawings, not the number, shape and size of the components when actually implemented. The shape, number and proportion of each component can be changed arbitrarily when actually implemented, and the component layout pattern can also be more complex.

[0019] All directionality indications (such as up, down, left, right, front, back, transverse, longitudinal...) in the utility model embodiment are only used to explain the relative position relationship, movement condition and the like between components in a certain specific posture, and if the specific posture changes, the directionality indications also change accordingly.

[0020] Due to installation errors and other reasons, the parallel relationship in the embodiment of the utility model may actually be an approximate parallel relationship, and the perpendicular relationship may actually be an approximate perpendicular relationship.

[0021] The utility model provides a kind of tire RFID electronic tag, including mutually connected carrier plate 1 and antenna 2, it is implanted in tire interior, as the exclusive identity mark of single tire.

[0022] Referring to Figure 1 And Figure 3 , carrier plate 1 is linear strip structure, the number of antenna 2 is set to two, and respectively set in the linear direction of carrier plate 1 two ends, the middle part of carrier plate 1 is provided with chip 11, chip 11 is provided with two pins, the two ends of the linear direction of carrier plate 1 are provided with solder joint 12 respectively, the two pins of chip 11 are set at solder joint 12 respectively, and are fixed by soldering with two antennas 2, form electric connection.

[0023] The surface of chip 11 is covered with bonding glue 3, and the bonding glue 3 is solidly connected to the carrier plate 1, forming packaging and protection of the chip 11.

[0024] Referring to Figure 2 , antenna 2 is spiral structure, the thickness or width of carrier plate 1 is less than the inner diameter of antenna 2, so that carrier plate 1 is inserted into antenna 2 with its length direction coaxial with the spiral axis of antenna 2, so that the circumference of antenna 2 is located outside the end of carrier plate 1, and the circumference of antenna 2 is connected with carrier plate 1 to form a package.

[0025] The above connection mode makes antenna 2 and carrier plate 1 more integrated, and the stress on antenna 2 and carrier plate 1 is more uniform under the deformation of tire in use, especially when antenna 2 deforms, most of the force is applied to carrier plate 1, rather than solder joint 12, thereby effectively avoiding the breakage and falling of solder joint 12, and effectively enhancing the connection strength between antenna 2 and carrier plate 1.

[0026] The middle part of carrier plate 1 is provided with a boss 13 protruding along the two sides perpendicular to the length direction, so that the whole carrier plate 1 is in a cross shape, and when antenna 2 and carrier plate 1 are connected, the ends of the two antennas 2 are respectively located on the two sides of boss 13 to form axial support and limiting for antenna 2.

[0027] The two ends of carrier plate 1 in length direction are respectively provided with a baffle 14, the baffle 14 is protruding along the two sides perpendicular to the length direction of carrier plate 1, a clamping groove with a certain length for accommodating a part of antenna 2 is formed between baffle 14 and boss 13, when antenna 2 and carrier plate 1 are connected, the two ends of antenna 2 in spiral axial direction are respectively located in boss 13 and baffle 14, thereby forming limiting for antenna 2 in spiral axial direction, avoiding antenna 2 from separating along the length direction of carrier plate 1.

[0028] The setting of the blocking piece 14 limits the mounting mode of the antenna 2 to the carrier plate 1, that is, the antenna 2 and the carrier plate 1 are connected and mounted in a relative rotation manner along the helical axis, and the setting of the blocking piece 14 makes the antenna 2 and the carrier plate 1 have good stability after being connected and mounted, and the relative position is not easy to change, so that the subsequent welding work of the welding spot 12 position can be more convenient and efficient.

[0029] Further, the clamping groove limits the antenna 2 on both sides in a manner, in combination with the axial elasticity of the helical antenna 2, when the antenna 2 and the carrier plate 1 are mounted, a set degree of compression can be applied to the antenna 2 in the clamping groove, the pitch of the antenna 2 in the clamping groove is adjusted to form a set value, which is different from the pitch of the antenna 2 outside the clamping groove, so as to adjust the resonant frequency and the radiation range of the antenna 2, and the compression state of the antenna 2 can be specifically referred to Figure 4

[0030] As preferred, the protruding direction and the protruding length of the boss 13 and the blocking piece 14 relative to the carrier plate 1 can be consistent, so that in the forming production work of the carrier plate 1, multiple carrier plates 1 connected in one piece can be formed at one time, and then the separation between the multiple carrier plates 1 is completed through laser cutting, thereby effectively improving the production efficiency.

[0031] Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor shall belong to the scope of protection of the present application.​
