Description

Technical Field

[0001] This utility model relates to the field of truck scale sensor technology, specifically a matching sensor for truck scales. Background Technology

[0002] In industrial production and logistics transportation, truck scales are key equipment for measuring the weight of goods, and the performance of their sensors directly affects the accuracy and stability of weighing results. Existing truck scale sensors have many problems.

[0003] Traditional sensor detection structures are prone to displacement deviations when exposed to vibrations and impacts during vehicle weighing, leading to inaccurate weight sensing at the detection terminals and significant weighing errors, failing to meet high-precision measurement requirements. Furthermore, under prolonged continuous operation, the heat generated by the sensor's internal electronic components cannot be dissipated effectively, and excessively high temperatures accelerate component aging, reducing the sensor's lifespan and reliability. Simultaneously, the wiring structure suffers from poor stability; in the vibration environment caused by frequent vehicle weighing, wiring is prone to loosening, resulting in signal transmission interruptions or data anomalies, increasing maintenance costs and measurement risks. Therefore, a matching sensor for truck scales is proposed. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model discloses a matching sensor for a truck scale, including a device housing 1. The inner wall of the device housing 1 is provided with multiple limiting grooves 10. The inner walls of the multiple limiting grooves 10 are slidably connected to sliders 9. The outer wall of the multiple sliders 9 is fixedly connected to a top sliding plate 2 at one end away from the limiting grooves 10. The top of the top sliding plate 2 is fixedly connected to multiple detection terminals 3, and the bottom of the top sliding plate 2 is fixedly connected to a sensing device 16. The sensing device 16 is located above the fixing frame 7.

[0023] A fixing frame 7 is fixedly connected to the bottom of the inner wall of the equipment casing 1, and multiple horizontal connecting rods 8 are fixedly connected to the bottom of the fixing frame 7.

[0024] Specifically, the supporting sensor for this truck scale uses the equipment housing 1 as the basic carrier to construct a functionally integrated and structurally compact system. The limiting groove 10 on the inner wall of the equipment housing 1, the slider 9, and the top sliding plate 2 work together to form the installation and movement structure of the detection terminal 3 and the sensing device 16, ensuring detection accuracy. The inner cavities 5 on both sides of the housing, the guide fan 6, and the heat dissipation box 4 form an efficient heat dissipation channel to maintain the stable operating temperature of the sensor. The fixing block 11, connector 12, guide interface 13, wiring port 15, and limiting slide rod 14 constitute a stable and well-protected wiring system to ensure stable and reliable signal transmission. The various structural parts cooperate with each other to achieve the performance advantages of high precision, high stability, and long life of the sensor. The multiple limiting grooves 10 symmetrically distributed on the inner wall of the equipment housing 1 cooperate with the slider 9 to ensure that the slider 9 slides smoothly in the groove and effectively limits its displacement in the non-weighing direction, ensuring the stability of the installation position of the detection terminal 3. The top sliding plate 2 provides a solid and reliable mounting platform for the detection terminals 3 and the sensing device 16. Multiple detection terminals 3 fixed to the top of the top sliding plate 2 accurately convert pressure signals into electrical signals. The sensing device 16 at the bottom of the top sliding plate 2 integrates high-performance signal amplification circuits, filtering circuits, and analog-to-digital conversion circuits. The mounting bracket 7 and crossbar 8 at the bottom of the inner wall of the device housing 1 are welded from high-strength steel, providing stable support for the sensing device 16 and enhancing the rigidity and vibration resistance of the overall sensor structure.

[0025] In this embodiment, an inner cavity 5 is provided on both sides of the outer wall of the equipment housing 1, and two guide fans 6 are fixedly connected to the inner walls of the two inner cavities 5.

[0026] Specifically, the inner cavities 5 carefully opened on both sides of the outer wall of the equipment housing 1 are connected to the internal space of the housing, forming symmetrically distributed heat dissipation channels, which can effectively improve air circulation efficiency and accelerate heat dissipation. The two guide fans 6 fixed on the inner wall of the inner cavity 5 are high-speed, low-noise axial flow fans, which can ensure the heat dissipation effect.

[0027] In this embodiment, a heat sink 4 is fixedly connected to one side of each of the two inner cavities 5, and both heat sinks 4 are located below the top sliding plate 2.

[0028] Specifically, the heat sink 4, fixed on one side of the inner cavity 5, is installed below the top sliding plate 2 and works in conjunction with the guide fan 6. When the guide fan 6 is activated, air flows from inside the sensor through the heat sink 4 to the outside, quickly carrying away the heat generated by the sensing device 16, keeping the internal temperature of the sensor at room temperature, and effectively extending the service life of the internal electronic components.

[0029] In this embodiment, two fixing blocks 11 are fixedly connected to the other side of the outer wall of the equipment housing 1, and a connector 12 is fixedly connected to one side of the outer wall of the two fixing blocks 11.

[0030] Specifically, the fixing block 11 on the other side of the outer wall of the equipment housing 1 is made of high-strength engineering plastic injection molding, which has good mechanical strength and insulation properties, and is used to securely fix the joint 12.

[0031] In this embodiment, the inner walls of both connectors 12 are slidably connected with guide interfaces 13, which are made of rubber.

[0032] Specifically, connector 12 is made of metal, and the inner wall of connector 12 and guide interface 13 adopt a sliding fit design. Guide interface 13 is made of highly elastic rubber material, which can tightly wrap the wiring port 15, providing reliable electrical connection and mechanical fixation, and effectively preventing wiring from loosening and external electromagnetic interference.

[0033] In this embodiment, the end of the guide port 13 away from the connector 12 is fixedly connected to the wiring port 15, which is located on the inner wall of the connector 12.

[0034] Specifically, the two limiting slide rods 14 fixed on the outer wall of the wiring port 15 precisely cooperate with the limiting groove on the inner wall of the connector 12 to ensure that the wiring port 15 is fixed in position within the connector 12. Even under strong vehicle vibration, it can effectively prevent the wiring port 15 from shifting. At the same time, the rubber guide 13 can completely isolate external pollutants such as dust and moisture from entering the interior of the connector 12, providing good protection for the wiring port 15 and improving the durability and reliability of the wiring structure.

[0035] In this embodiment, two limiting slide rods 14 are fixedly connected to the outer wall of the wiring port 15, and both limiting slide rods 14 are slidably connected to the inner wall of the connector 12.

[0036] Specifically, by setting a limit slide bar 14, the wiring port 15 will not detach from the connector 12.

[0037] The working principle and usage process of this utility model are as follows: When a vehicle enters the truck scale platform, its weight is transferred to the sensor's detection terminal 3 via the platform. Under pressure, the resistance value of the strain gauge at the detection terminal 3 changes. According to the Wheatstone bridge principle, the pressure signal is converted into a weak electrical signal output. This weak electrical signal is transmitted to the sensing device 16 at the bottom of the top sliding plate 2, where the analog electrical signal is accurately converted into a digital signal, facilitating data processing, display, and transmission by the truck scale weighing system. During sensor operation, the electronic components inside the sensing device 16 generate heat. When the internal temperature of the sensor rises to a set threshold, the guide fan 6 automatically starts. Under the action of the guide fan 6, air flows from the inside of the device casing 1 through the inner cavity 5 to the heat dissipation box 4. As the air flows through the heat dissipation box 4, the heat is quickly dissipated into the surrounding environment, cooling the sensing device 16 and ensuring its stable operation in a suitable temperature environment. When connecting external devices, the plug of the connecting cable is inserted into the wiring port 15. The plug, under the elastic wrapping of the guide interface 13, fits tightly against the wiring port 15, forming a reliable electrical connection. Meanwhile, the limiting slide bar 14 engages with the limiting groove on the inner wall of the connector 12 to fix the position of the wiring port 15 and prevent the plug from becoming loose. The rubber conductive interface 13 not only ensures the stability of the electrical connection, but also effectively blocks external dust, moisture and other contaminants from corroding the wiring port 15, ensuring stable and reliable signal transmission between the sensor and the weighing display instrument.
