Detailed Implementation

[0025] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0026] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0027] Please refer to Figure 1 and Figure 2This application provides a transport vehicle for magnetic core pallets. The transport vehicle includes a vehicle body 100 and a weighing device 200. Forks 110 are located at the bottom of the vehicle body 100, primarily used for transporting magnetic cores. The weighing device 200 is positioned on the transport surface of the forks 110. The weighing device 200 includes a slide rail 210 and a weighing element 220. The slide rail 210 is arranged along the length of the forks 110. The weighing element 220 is slidably connected to the slide rail 210 and can slide along the slide rail 210. The weighing element 220 has a built-in load cell (not shown in the figure) for weighing the magnetic core. In actual operation, the magnetic core is placed on the transport surface of the forks 110, and the weighing device 200 positioned on the transport surface can then perform real-time weighing of the magnetic core during transport. However, due to the special nature of the magnetic core manufacturing process, there may be gaps on its surface caused by the molding die structure or internal structure design. These gaps will prevent the magnetic core from making full contact with the weighing sensor built into the weighing component 220, thereby affecting the accuracy and effectiveness of weighing.

[0028] The weighing device 200 provided in this application includes a slide rail 210 and a weighing element 220, which can slide along the length of the slide rail 210, i.e., the fork 110. When the initial position of the weighing element 220 is exactly aligned with the notch of the magnetic core, making accurate weighing impossible, the operator can slide the weighing element 220 to adjust it to a position corresponding to the part of the magnetic core without the notch. In this way, the magnetic core can achieve good contact with the weighing sensor, thereby ensuring the smooth progress of the weighing process and the accuracy of the weighing result, improving the reliability and applicability of the pallet truck in practical applications. The mechanical structure of the slider 223 and the slide rail 210 can be a slider 223 and a linear guide, a rack and pinion, an electric push rod, a hydraulic cylinder and a pneumatic cylinder, etc. The top, bottom, and vertical positional relationships mentioned in this document are based on the normal operating state of the pallet truck. The surface of the weighing device that contacts the goods is an elastic plate. When the goods are placed on the elastic plate, the elastic plate will deform and press against the weighing component 220. When no magnetic core is placed, the elastic plate will spring back.

[0029] Combination Figure 3In one embodiment, the slide rail 210 is a threaded screw, and the weighing component 220 includes a slider 223. The slider 223 has a threaded hole, and the slider 223 engages with the threaded screw through the threaded hole to achieve transmission. When the threaded screw rotates, the slider 223 moves along the axial direction of the screw. Specifically, as the threaded screw rotates, the threaded hole on the slider 223 interacts with the thread of the screw, pushing the slider 223 to slide on the screw. Specifically, in the electronic control system of the transport vehicle, the vehicle body 100 is equipped with a rotary motor, which is directly connected to the threaded screw. The motor precisely controls the rotation of the threaded screw, allowing the slider 223 to slide smoothly along the screw. In this embodiment, the position of the slider 223 changes continuously and is precisely adjustable, ensuring that the weighing component 220 is flexibly positioned to adapt to different magnetic core shapes, significantly improving weighing accuracy and the working efficiency of the transport vehicle.

[0030] In one embodiment, the weighing device 200 includes at least a first weighing element 221 and a second weighing element 222. The first weighing element 221 includes a first slider 223a, and the second weighing element 222 includes a second slider 223b. The threaded rod includes a front half near the vehicle body 100 and a rear half away from the vehicle body 100. The front and rear halves can be symmetrical about the center of the threaded rod. The threads of the front and rear halves have opposite directions of rotation, and the threaded holes of the first slider 223a and the second slider 223b have opposite directions of rotation. The first slider 223a is located in the front half and engages with the threaded rod, while the second slider 223b is located in the rear half and engages with the threaded rod. When the threaded rod rotates, the first and second sliders can move closer to or further away from each other depending on the direction of rotation. If the lead screw rotates clockwise, the first slider slides to the left and the second slider slides to the right, moving them away from each other. Conversely, if the lead screw rotates counterclockwise, the first slider slides to the right and the second slider slides to the left, moving them closer together. This design eliminates the need for a complex transmission mechanism while ensuring the synchronicity and accuracy of the two slider movements. This synchronicity helps to evenly distribute the weight of the magnetic core, avoiding measurement errors caused by uneven force on one side and improving weighing accuracy.

[0031] In one embodiment, the weighing component 220 includes a weighing plate 224, which is fixedly connected to the slider 223 via a damper 225. A load cell is embedded in the weighing plate 224. The damper 225 can be, for example, a viscous damper or an elastic damper. During transport, if bumps or vibrations occur, the damper 225 can absorb the vibration energy through viscous or elastic resistance, reducing the vibration of the weighing plate 224. This improves the reliability of the weighing device 200 in complex transport environments, reduces the negative impact of bumps on weighing accuracy, and extends the service life of the load cell.

[0032] refer to Figure 4In one embodiment, the weighing plate 224 is rectangular, and four dampers 225 are included. The four dampers 225 are fixedly connected to the slider 223 at the four corners of the weighing plate 224. The four dampers 225 are located at the four corners of the weighing plate 224, which can evenly distribute vibration energy, effectively buffer and absorb vibrations from different directions, and ensure that the weighing plate 224 is more stable when transporting goods.

[0033] refer to Figure 5 In another embodiment, the weighing plate 224 is circular, and the dampers 225 include four dampers arranged in a rectangular pattern, fixing the weighing plate 224 to the slider 223. The circular weighing plate 224, combined with the rectangularly distributed dampers 225, better disperses weight and impact force. The circular plate ensures that the weight of the goods is evenly distributed to the surrounding dampers 225, avoiding excessive localized stress and reducing the risk of damage to the weighing plate 224 and dampers 225.

[0034] In one embodiment, the transport vehicle further includes an infrared rangefinder 300 and a display component (not shown in the figure), wherein the infrared rangefinder 300 is electrically connected to the display component; along the length direction of the forks 110, the infrared rangefinder 300 is installed at the end of the first slider 223a and the second slider 223b near the vehicle body 100, and the infrared rangefinder 300 is installed at the end of the threaded rod away from the vehicle body 100; or along the length direction of the forks 110, the infrared rangefinder 300 is installed at the end of the first slider 223a and the second slider 223b away from the vehicle body 100, and the infrared rangefinder 300 is provided at the end of the threaded rod near the vehicle body 100. The following description assumes that the first slider 223a is closer to the vehicle body 100 than the second slider 223b. This setup allows the infrared rangefinder 300 to measure the distance between the end of the threaded rod closest to the vehicle body 100 and the first slider 223a, the distance between the first slider 223a and the second slider 223b, and the distance between the second slider 223b and the end of the threaded rod furthest from the vehicle body 100. This data is then transmitted to the display component via electrical signals. The display component presents the specific distance values ​​in real time, enabling the operator to intuitively grasp the current position and remaining movable distance range of the first slider 223a and the second slider 223b. This setup helps the operator precisely control the position of the slider 223, ensuring that the slider 223 moves to the ideal weighing area, improving weighing accuracy, and preventing equipment damage caused by excessive movement of the slider 223, thus optimizing the weighing efficiency of the transport vehicle. The infrared rangefinder 300 measures and displays the distance by emitting and receiving reflected infrared light, calculating the time difference or phase difference.

[0035] In one embodiment, the weighing device 200 includes a weighing section 201 and a loading section 202. The loading section 202 is located away from the vehicle body 100 relative to the weighing section 201. A guide wheel 203 is fixed to the bottom end of the loading section 202, and the top surface of the loading section 202 is arc-shaped. The main function of the guide wheel 203 is to help the forks 110 maintain stability and correct orientation during lifting and lowering, ensuring that the forks 110 can smoothly lift and lower goods. It also provides support and guidance when the pallet truck moves. The loading section 202 provides a stable mounting position and room for movement for the guide wheel 203. The arc-shaped top surface design makes it easier for goods to slide onto the forks 110, improving loading convenience.

[0036] In one embodiment, an infrared rangefinder 300 is provided on the side wall of the vehicle body 100 facing the cargo. This rangefinder can measure the distance between the cargo and the vehicle body 100, and based on the positional relationship between the vehicle body 100 and the forks 110, can analyze the position of the cargo on the forks 110, which is then displayed in real-time on a display component. Operators can monitor the cargo's position in real time, ensuring accurate handling and preventing cargo from shifting or falling during transport.
