[0017] The technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model, obviously, the described embodiment only some embodiments of the utility model, instead of all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by ordinary skilled person in the art without making creative labor belong to the protection scope of the utility model.

[0018] Because sensor is too long, Figure 1 It is the explosion structure schematic diagram drawn by intercepting sensor part. As Figure 1 Shown, a kind of sensor for identifying large tonnage truck tire, including: aluminum groove 1, T type nut 2, fixed ground needle 3, nylon block 4, rubber block 5 and contact bolt 6.

[0019] A threaded hole is arranged at the bottom of the aluminum groove 1.

[0020] The nylon block 4 and the T-shaped nut 2 form a mortise and tenon structure. The nylon block 4 has a sliding groove structure, and the outer dimensions of the nylon block 4 are connected with the T-shaped nut 2 through the mortise and tenon structure designed with care. The sliding groove structure of the nylon block 4 is adapted to the groove of the T-shaped nut 2, and the two are mutually fitted. Not only is the installation convenient, but also the connection is tight, which effectively prevents impurities such as dust and moisture from invading the inside of the sensor from the gap. The nylon block 4 with the T-shaped nut 2 is like a cover covering the aluminum groove 1, as shown in Figure 4 .

[0021] The wire is firmly installed below the T-shaped nut 2. The specification of the wire is selected according to the electrical parameter requirements such as voltage and current of the sensor. For example, copper core wire is selected to ensure good electrical conductivity. The connection between the wire and the T-shaped nut 2 adopts welding or professional crimp terminal connection mode to ensure firm connection and extremely small contact resistance.

[0022] The wire below the T-shaped nut 2 and the contact bolt 6 jointly constitute a switching device.

[0023] The contact bolt 6 is in the shape of a hollow cylinder and is composed of three cylinders. The inner diameters of the three cylinders are the same. The outer diameter of the upper cylinder is adapted to the through hole of the T-shaped nut 2. The outer diameter of the lower cylinder is larger than that of the upper cylinder and smaller than that of the middle cylinder. The outer diameter of the middle cylinder is adapted to the hole of the rubber block 5. The lower cylinder and the middle cylinder of the contact bolt 6 are nested in the rubber block 5, and the upper cylinder is sleeved into the through hole of the T-shaped nut 2.

[0024] The rubber block 5 is internally provided with a hole, and the contact bolt 6 is installed in the rubber block 5 and is fixed to the threaded hole at the bottom of the aluminum groove 1 by the fixed needle 3. At the same time, in the vertical direction, a buffer space of 20 millimeters is intentionally left between the rubber block 5 and the bottom of the aluminum groove 1 and the nylon block 4 above, as shown in Figure 2 . This buffer space not only allows the rubber block 5 to have enough deformation allowance when it is pressed, but also avoids damage to the components due to excessive compression, thereby ensuring the reliable triggering of the switching action and maintaining the stability and reliability of the switching device.

[0025] The aluminum groove 1 is made of aluminum alloy with certain strength and corrosion resistance, which can provide a stable and reliable accommodation space for the internal sensor elements and effectively block physical damage such as collision and extrusion from the outside.

[0026] The nylon block 4 covers the sensor above to form a sealed cover, which uses the chemical corrosion resistance and light weight of nylon material to provide additional protection for the sensor, preventing dust, moisture and other impurities from invading, and providing an additional protective barrier for the sensor.

[0027] The contact bolt 6 is one of the key components of the voltage switch, which is made of hard cast iron material, and its manufacturing process is strictly controlled to ensure smooth surface and clear thread, so as to ensure good cooperation with other components.

[0028] The fixed needle 3 is made of high-strength alloy steel.

[0029] The contact bolt 6 is precisely installed in the hole pre-set in the rubber block 5, and the elastic modulus of the rubber block 5 is tested and optimized, generally selected between 0.5-3MPa, to ensure that moderate compression deformation can be generated under the rolling of the vehicle.

[0030] Then, the rubber block 5 with the contact bolt 6 is screwed into the threaded hole arranged at the bottom of the aluminum groove 1 through the fixed needle 3, so that the position of the contact bolt 6 can be stable under various complex conditions when the vehicle passes through the tire identification sensor, laying a foundation for forming a stable switch condition.

[0031] When detecting the number of tires per axle, when the vehicle tire passes through the tire identification sensor, the pressure is transmitted to the nylon block 4, so that the rubber block 5 is compressed, so that the contact bolt 6 placed therein is connected with the wire below the T-shaped nut 2 to generate a current signal, and the number of tires and the width of the tire tread are determined according to the number of generated charge signals.

[0032] When the vehicle passes through the rolling, the rubber block 5 is compressed, so that the contact bolt 2 placed therein is connected with the wire, and the switch state is turned on. After the vehicle passes, the rubber block 5 returns to the original state, and the switch state is turned off, realizing the automatic switching function of the tire identification.

[0033] Because the sensor is too long, in order to facilitate customization, the whole sensor is divided into multiple modules for assembly, as shown in Figure 3 、 Figure 5 .

[0034] Through the above specific embodiments, the internal structure design of the sensor for large-tonnage truck tire identification is effectively realized, which fully plays its advantages of stable structure, low cost, automatic identification and the like, and meets the actual needs of the highway transportation field for large-tonnage truck tire identification.

[0035] Finally, it should be noted that: the above examples are only used to illustrate the technical scheme of the utility model and not to limit it; although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that: the specific embodiments of the utility model can be modified or some technical features can be replaced by equivalents: without departing from the spirit of the utility model technical scheme, all of them should be covered in the technical scheme range of the application claimed.
