[0040] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0041] The intelligent weighing structure of a commercial vehicle disclosed in the embodiments of the present application is installed on a commercial vehicle and used for weighing the actual load weight of the vehicle.

[0042] Referring to Figure 1 and Figure 2The application discloses a commercial vehicle intelligent weighing structure, which comprises a sensor assembly 10, a processing module 20 and a display module 30, wherein the sensor assembly 10 is fixed on a vehicle frame and an axle 40, the processing module 20 is electrically connected with the sensor assembly 10 and the display module 30 respectively, the processing module 20 can convert displacement change values obtained by the sensor assembly 10 into weight values, and the weight values are displayed through the display module 30, so that accurate weighing of the commercial vehicle is realized.

[0043] The sensor assembly 10 comprises a first fixing member 11, a second fixing member 12 and a sensor, one end of the first fixing member 11 is fixed on the vehicle frame, the other end of the first fixing member 11 is provided with a first sleeve 111, a through hole 112 is arranged on the end of the first sleeve 111 close to the vehicle frame, and the through hole 112 is used for allowing a wire connected with the sensor to pass through, one end of the second fixing member 12 is fixed on the axle 40, the other end of the second fixing member 12 is provided with a second sleeve 121, and the second sleeve 121 is inserted into the first sleeve 111, and the sensor is arranged in the first sleeve 111 and used for sensing the relative displacement between the first sleeve 111 and the second sleeve 121.

[0044] Specifically, the first fixing member 11 and the second fixing member 12 are made of metal materials, such as stainless steel or aluminum alloy, so as to ensure the strength and corrosion resistance, one end of the first fixing member 11 is fixed on the vehicle frame through a universal screw 13 and a support 14 in a welding mode, the inner diameter of the first sleeve 111 at the other end of the first fixing member 11 is slightly larger than the outer diameter of the second sleeve 121, so that the second sleeve 121 can be smoothly inserted and moved, one end of the second fixing member 12 can be fixed on the axle 40 through welding or a bolt, and the outer diameter of the second sleeve 121 at the other end of the second fixing member 12 is slightly smaller than the inner diameter of the first sleeve 111, so that a good matching gap is ensured.

[0045] The sensor is a displacement sensor, such as an optical sensor or a Hall effect sensor, wherein the installation position and angle of the displacement sensor can be adjusted according to actual conditions, so as to ensure the best measurement effect, and the displacement sensor is connected with the processing module 20 through a cable, and the cable can be a shielded cable, so as to reduce electromagnetic interference and improve the stability of signal transmission.

[0046] It is worth mentioning that the through hole 112 not only allows the cable to pass through, but also facilitates air to enter and exit when the first sleeve 111 and the second sleeve 121 move relatively.

[0047] Further, the first fixing member 11 and the second fixing member 12 are fixed on the vehicle frame and the axle 40 through the support 14 fixed by the universal screw 13 and welding, so that even if the first fixing member 11 and the second fixing member 12 are loosened when the vehicle runs on a bumpy road, the stability and accuracy of the sensor can be ensured.

[0048] Wherein, the design of the universal screw makes the first fixing member 11 and the second fixing member 12 can be freely adjusted within a certain range to adapt to different vehicle models and different road conditions.

[0049] Further, the sensor assembly 10 can be set to multiple, fixed on the axle 40.

[0050] Wherein, based on different vehicle models, the number of axles 40 is different, and different numbers of sensor assemblies 10 can be set to improve the accuracy of the commercial vehicle weighing system.

[0051] Referring to Figure 3 When the vehicle's axle 40 only includes the first axle 41 and the second axle 42, the sensor assembly 10 is set to 2, the first axle 41 upper end corresponds to the vehicle head, and the second axle 42 corresponds to the vehicle frame.

[0052] Wherein, the sensor assembly 10 is set to 2, fixed on the second axle 42, and respectively located at both ends of the second axle 42. In this way, the weight distribution of the vehicle frame can be more comprehensively monitored, and the accuracy and stability of the weighing can be improved.

[0054] Wherein, the sensor assembly 10 is set to 2, fixed on the second axle 42, and respectively located at both ends of the second axle 42, 2 sensor assemblies 10 are fixed on the third axle 43, and respectively located at both ends of the third axle 43. In this way, the weight distribution of the front and rear of the vehicle frame can be more accurately detected. This layout makes the sensor can more comprehensively perceive the load change at different positions, and improves the accuracy and reliability of the weighing result.

[0055] Referring to Figure 5 When the vehicle's axle includes the first axle 41, the second axle 42, the third axle 43 and the fourth axle 44, the second axle 42 is located between the first axle 41 and the third axle 43, the third axle 43 is located between the second axle 42 and the fourth axle 44, the first axle 41 upper end corresponds to the vehicle head, and the second axle 42, the third axle 43 and the fourth axle 44 correspond to the vehicle frame.

[0056] The sensor assembly 10 is arranged in six groups, two of which are fixed on the second axle 42 and located at both ends of the second axle 42, two of which are fixed on the third axle 43 and located at both ends of the third axle 43, and two of which are fixed on the fourth axle 44 and located at both ends of the fourth axle 44. In this way, the weight difference of the vehicle frame front and rear and left and right can be more finely monitored, especially in long-distance transportation and complex road conditions, to avoid overloading in a certain area and affecting the form safety.

[0057] It is explained that the number of sensor assemblies 10 can be set based on the type and needs of the vehicle, and in this embodiment, it is not limited.

[0058] In addition, the sensor assembly 10 also includes a dust cover covering the outside of the first sleeve 111 and the second sleeve 121 to prevent dust from entering the inside of the sensor assembly 10.

[0059] The dust cover is made of flexible material, such as rubber or silicone, which can effectively block dust and moisture without affecting the normal operation of the sensor assembly 10. The length and diameter of the dust cover can be adjusted according to actual conditions to ensure complete coverage of the outside of the first sleeve 111 and the second sleeve 121, while not affecting the movement of the sensor assembly 10.

[0060] In summary, the commercial vehicle intelligent weighing structure disclosed in the embodiments of the present application sets a sensor assembly 10 between the axle and the frame, uses a sensor to sense the relative distance change between the first sleeve 111 and the second sleeve 121, and converts the distance change value into a weight value through the processing module 20, improving the accuracy and reliability of the commercial vehicle weighing; the first fixing member 11 and the second fixing member 12 are fixed on the frame and the axle through universal screws, ensuring the stability of the sensor assembly 10 and the convenience of installation, reducing errors caused by mechanical vibration; the design of the dust cover effectively prevents dust from entering the inside of the sensor assembly 10, prolongs the service life of the sensor assembly 10, and ensures the long-term stable operation of the weighing system.
