[0040] This application proposes a pressure detection device 200 .

[0041] See also Figure 6 and Figure 8 In one embodiment of the present application, the pressure detection device 200 is applied to a material transport vehicle 10, which can travel on a track. The pressure detection device 200 includes a mounting seat 210, a first guide shaft 220, a pressure detection module 230, and a floating wheel module 240. The mounting seat 210 is used to be relatively fixed to the frame 100 of the material transport vehicle 10; one end of the first guide shaft 220 is connected to the mounting seat 210; the pressure detection module 230 is arranged on the first guide shaft 220; the floating wheel module 240 includes a connected sliding member 241 and a floating wheel 242. The sliding member 241 is sleeved on the first guide shaft 220 and is arranged between the mounting seat 210 and the pressure detection module 230. The circumference of the floating wheel 242 is used to rotatably abut one side surface of the track distributed in its width direction. The floating wheel 242 can drive the sliding member 241 to move axially along the first guide shaft 220 under the abutment action of the track, so that the sliding member 241 squeezes the pressure detection module 230.

[0042] Mounting base 210 is relatively fixed to the frame 100 of the material transport vehicle 10, providing a mounting location and support for other components. Mounting base 210 can be fixed to the frame 100 by welding or other methods, or it can be removably fixed to the frame 100 by means of a snap connection, magnetic connection, or screw connection. Mounting base 210 can be directly fixed to the frame 100 or relatively fixed to the frame 100 by other components.

[0043] One end of the first guide shaft 220 is connected to the mounting base 210. The first guide shaft 220 is used to guide the movement of the slider 241, ensuring that the slider 241 can move smoothly along the predetermined path (i.e., the axis of the first guide shaft 220). The floating wheel 242 can rotate freely about its axis, with its edge in close contact with the side of the track. When the material transport vehicle 10 travels along the track, it will exert lateral pressure or collision on the track, exerting pressure on the track side. At the same time, the track side also generates a reaction force on the floating wheel 242, causing the floating wheel 242 to change its position, thereby pushing the slider 241 along the first guide shaft 220. The slider 241 is used to transmit the force from the floating wheel 242 to the pressure detection module 230, which is responsible for the actual pressure measurement. When the slider 241 moves due to the force generated by the floating wheel 242 contacting the track, it directly or indirectly acts on the pressure detection module 230, generating a corresponding electrical output signal.

[0044] By installing the pressure detection device 200 on the frame 100 of the material transport vehicle 10, the pressure detection device 200 can monitor the lateral pressure exerted on the track in real time when the material transport vehicle 10 moves along the track, so that the material transport vehicle 10 can perform differential control on different wheels 400 of the material transport vehicle 10 according to the lateral pressure exerted on the track, and then the material transport vehicle 10 can adjust the lateral pressure of the wheels 400 on the track in real time, so that the material transport vehicle 10 will not have a side collision with the track during transportation, so as to improve the safety of the material transport vehicle 10 running on the track and protect the track at the same time.

[0045] The technical solution of the present application is to enable the floating wheel 242 to drive the sliding member 241 to move axially along the first guide shaft 220 under the abutment action of the track, so that the sliding member 241 squeezes the pressure detection module 230, so that the pressure detection module 230 can monitor the lateral force acting on the floating wheel 242 in real time. When the pressure detection device 200 is relatively fixed on the frame 100 of the material transport vehicle 10, the peripheral side of the floating wheel 242 can rotatably abut one of the side surfaces of the track distributed in its width direction, the pressure detection module 230 can monitor in real time the lateral pressure applied by the material transport vehicle 10 on the track, so that the material transport vehicle 10 can adjust the lateral pressure of the material transport vehicle 10 on the track by differentially adjusting its wheels 400, reduce the extrusion and collision of the material transport vehicle 10 on the track, and thereby improve the safety of the material transport vehicle 10 running on the track and protect the track.

[0046] In one embodiment, see Figure 8 The sliding member 241 includes a sliding portion 2411 and a connecting portion 2412 connected at an angle. The sliding portion 2411 is sleeved on the first guide shaft 220. The connecting portion 2412 protrudes from the side of the mounting seat 210 away from the sliding portion 2411. The floating wheel 242 is rotatably connected to one end of the connecting portion 2412 away from the sliding portion 2411.

[0047] The sliding portion 2411 is sleeved onto the first guide shaft 220, ensuring smooth movement of the sliding member 241 on the guide shaft. The connecting portion 2412 extends outward from the sliding portion 2411 and protrudes from the mounting seat 210. It forms a predetermined angle with the sliding portion 2411 to ensure that the floating wheel 242 can stably contact the side of the track. The floating wheel 242 can transmit lateral pressure exerted on the track to the connecting portion 2412, which is then transmitted to the pressure detection module 230 via the sliding portion 2411. This transfers lateral pressure while reducing the risk of interference between the mounting seat 210 and the side of the track. The floating wheel 242 can be configured as a bearing rubber wheel, the outer ring of which rotatably abuts the track, and the inner ring of which is fixedly connected or hinged to the floating wheel 242. The floating wheel 242 can also be configured as a roller, which is fixedly connected or hinged to the connecting portion 2412 via a shaft.

[0048] In other embodiments, only the sliding portion 2411 may be provided, with the floating wheel 242 connected below the sliding portion 2411. The diameter of the floating wheel 242 may be increased to prevent the mounting seat 210 from interfering with the side surface of the track.

[0049] In one embodiment, see Figure 8 The floating wheel module 240 further includes a shaft sleeve 243 , and the sliding portion 2411 is sleeved on the first guide shaft 220 through the shaft sleeve 243 .

[0050] The sleeve 243 is made of a wear-resistant material and can be configured as a copper sleeve, steel sleeve, or nylon sleeve. The sleeve 243 significantly reduces the frictional resistance between the sliding portion 2411 and the first guide shaft 220, allowing the sliding portion 2411 to move more smoothly along the first guide shaft 220. This helps improve the material transport vehicle 10's response speed and detection accuracy to changes in track lateral pressure, ensuring the accuracy and real-time nature of pressure detection results. Furthermore, the sleeve 243 protects the first guide shaft 220 from wear, extending its service life.

[0051] In other embodiments, the sliding portion 2411 may be mounted on the first guide shaft 220 via a linear bearing to effectively support and guide the linear reciprocating motion of the sliding portion 2411. The linear bearing can reduce friction during the sliding portion 2411 sliding along the first guide shaft 220 while maintaining high precision and smooth operation.

[0052] In one embodiment, see Figure 8The pressure detection module 230 includes a first pressure plate 231, a second pressure plate 232 and a first sensor 233. The first pressure plate 231 is arranged between the sliding member 241 and the first sensor 233, and the second pressure plate 232 is arranged on the side of the first sensor 233 away from the first pressure plate 231. The first pressure plate 231 can move axially along the first guide shaft 220 and squeeze the first sensor 233 under the push of the sliding member 241.

[0053] The slider 241, first pressure plate 231, first sensor 233, and second pressure plate 232 are sequentially arranged axially along the first guide shaft 220. The second pressure plate 232 provides a fixed fulcrum, ensuring stable operation of the first sensor 233 when subjected to pressure, thereby preventing displacement of the first sensor 233. As the slider 241, driven by the floating wheel 242, moves toward the pressure detection module 230, the first pressure plate 231, pushed by the slider 241, moves axially along the first guide shaft 220, transmitting the lateral pressure from the slider 241 to the first sensor 233. The first sensor 233 senses the pressure change and converts it into an electrical signal for output. The reaction force of the lateral pressure on the track is transmitted sequentially through the floating wheel 242, the slider 241, and the first pressure plate 231, ultimately to the first sensor 233, enabling the first sensor 233 to monitor the track's lateral pressure in real time.

[0054] In other embodiments, the pressure detection module 230 may be provided with only the first sensor 233, with the mounting base 210, the first sensor 233, and the sliding member 241 being sequentially arranged along the axial direction of the first guide shaft 220. The first sensor 233 is mounted on the mounting base 210, and under the abutment of the track, the floating wheel 242 can drive the sliding member 241 to move along the axial direction of the first guide shaft 220, directly pressing the first sensor 233.

[0055] In one embodiment, see Figure 8 The pressure detection device 200 also includes a third pressure plate 260 and an elastic member 250. The third pressure plate 260 is sleeved on the first guide shaft 220 on the side of the second pressure plate 232 away from the first pressure plate 231 and can be fixed relative to the first guide shaft 220. The elastic member 250 is sleeved on the first guide shaft 220, with one end abutting the third pressure plate 260 and the other end abutting the second pressure plate 232.

[0056] The third pressure plate 260 can be fixed relative to the first guide shaft 220 to provide a fixed fulcrum for supporting the elastic member 250. The elastic member 250 is used to provide a restoring force, ensuring that after the reaction force of the track on the floating wheel 242 decreases or disappears, the first pressure plate 231 and the sliding member 241 can return to their initial positions, and the circumference of the floating wheel 242 can maintain contact with the side of the track to prevent failure of the pressure detection device 200. At the same time, the elastic member 250 can absorb and buffer external forces, preventing excessive impact forces from directly acting on the first sensor 233, thereby protecting the first sensor 233 from damage.

[0057] In other embodiments, the elastic member 250 can also be positioned between the first pressure plate 231 and the sliding member 241. Furthermore, a rubber pad or magnetic buffer can be positioned between the third pressure plate 260 and the second pressure plate 232. Rubber pads offer excellent elasticity, shock absorption, and wear resistance, providing a gentle cushioning effect. Magnetic buffers utilize the repulsive or attractive forces between magnets to provide both cushioning and restoring forces, offering contactless and wear-free operation.

[0058] In one embodiment, see Figure 8 The pressure detection device 200 also includes an adjusting rod 270, which is arranged side by side with the first guide shaft 220. One end of the adjusting rod 270 is rotatably connected to the mounting seat 210 and is relatively fixed to the mounting seat 210 in the axial direction of the adjusting rod 270. The other end of the adjusting rod 270 is screwed to the third pressure plate 260; the third pressure plate 260 is slidingly connected to the first guide shaft 220 in the axial direction of the first guide shaft 220.

[0059] The third pressure plate 260 can be fixed relative to the first guide shaft 220 or can be movable relative to the first guide shaft 220. When the adjustment rod 270 rotates, it can drive the third pressure plate 260 to move axially along the adjustment rod 270, and at the same time, the third pressure plate 260 can move on the first guide shaft 220. The adjustment rod 270 is used to adjust the position of the third pressure plate 260 on the first guide shaft 220. When the adjustment rod 270 rotates forward, the third pressure plate 260 can move toward the second pressure plate 232 on the adjustment rod 270 and compress the elastic member 250, so that the elastic member 250 applies a preload force to the track. This preload force adjusts the pressure between the floating wheel 242 and the track to meet the initial lateral pressure requirement of the material transport vehicle 10 on the track. The design of the adjustment rod 270 allows the pressure detection device 200 to adjust the preload force of the elastic member 250 according to different application requirements, thereby improving the adaptability and flexibility of the pressure detection device 200. When the adjustment rod 270 is reversed, the third pressure plate 260 can move away from the second pressure plate 232 on the adjustment rod 270, and the elastic member 250 resumes its deformation. By manually or automatically adjusting the position of the third pressure plate 260 on the first guide shaft 220, the initial lateral pressure requirement of the material transport vehicle 10 on the track is met when switching between different material transport vehicles 10 or different track spacings. This allows the material transport vehicle 10 to adapt to different track spacings, thereby improving the compatibility of the pressure detection device 200.

[0060] In one embodiment, one end of the adjustment rod 270 is threadedly connected to the third pressure plate 260, and the other end is sleeved on the mounting base 210. Rotating the adjustment rod 270 allows the third pressure plate 260 to move in the axial direction of the adjustment rod 270. The adjustment rod 270 is arranged parallel to the first guide shaft 220, so that the third pressure plate 260 can compress the elastic member 250. In another embodiment, one end of the adjustment rod 270 is fixedly connected to the third pressure plate 260, and the other end is threadedly connected to the mounting base 210. In another embodiment, one end of the adjustment rod 270 is fixedly connected to the third pressure plate 260, and the other end is sleeved on the mounting base 210. The adjustment rod 270 is movable in its axial direction via a linear motor or a servo motor.

[0061] This application also proposes a material transport vehicle 10, see Figure 1 and Figure 2 The material transport vehicle 10 includes a frame 100, a control module 500, multiple wheels 400 and a pressure detection device 200. The specific structure of the pressure detection device 200 refers to the above embodiment. Since the material transport vehicle 10 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0062] The wheel 400 and the control module 500 are installed on the vehicle frame 100 , the pressure detection device 200 is electrically connected to the control module 500 , and the control module 500 can adjust the speed of the wheel 400 according to the pressure signal sent by the pressure detection device 200 .

[0063] The material transport vehicle 10 also includes an obstacle avoidance radar, a safety edge, a protective housing, and a battery. The frame 100 is used to mount and secure other components, providing support and stability. The protective housing is fixedly connected to the frame 100 via screws. The obstacle avoidance radar and safety edge are each provided in two groups, one located at the front of the frame 100 and the other at the rear of the frame 100, and are fixedly connected to the protective housing via screws. The battery and control module 500 are arranged in the middle of the frame 100 and are protected and waterproofed by the protective housing. The control module 500 is responsible for receiving and processing the pressure signal from the pressure detection device 200 and adjusting the speed of the wheels 400 based on the pressure signal. Multiple wheels 400 are installed at the bottom of the frame 100 and are responsible for supporting the vehicle so that it can travel along the track. The speed of the wheels 400 can be dynamically adjusted through the adjustment of the control module 500.

[0064] The elastic member 250 is compressed by adjusting the lever 270 and the third pressure plate 260 to adjust the lateral pressure between the floating wheel 242 and the track to meet the initial lateral pressure requirement of the material transport vehicle 10 on the track. After the initial lateral pressure is set, the material transport vehicle 10 operates on the track. The track has a first side and a second side relative to each other in its width direction. When the pressure detection device 200 detects a higher lateral pressure on the first side of the track, the control module 500 controls the differential movement of the wheels 400 to deflect the vehicle toward the second side of the track to reduce the pressure on the first side. When the pressure detection device 200 detects a lower lateral pressure on the first side of the track, the control module 500 controls the differential movement of the wheels 400 to deflect the vehicle toward the first side of the track to increase the pressure on the first side. Based on the pressure value monitored by the pressure detection device 200, the wheels 400 are differentially adjusted to adjust the lateral pressure of the wheels 400 on the track in real time, ensuring that the lateral pressure between the wheels 400 equipped with the pressure detection device 200 and the track remains within a reasonable range.

[0065] By installing the pressure detection device 200 on the frame 100 of the material transport vehicle 10, the pressure detection device 200 can monitor the lateral pressure exerted on the track in real time when the material transport vehicle 10 moves along the track, so that the material transport vehicle 10 can perform differential control on different wheels 400 of the material transport vehicle 10 according to the lateral pressure exerted on the track, and then the material transport vehicle 10 can adjust the lateral pressure of the wheels 400 on the track in real time, so that the material transport vehicle 10 will not have a side collision with the track during transportation, so as to improve the safety of the material transport vehicle 10 running on the track and protect the track at the same time.

[0066] In addition, the material transport vehicle 10 can be used to transport photovoltaic modules during the laying process. The material transport vehicle 10 does not need to lay a dedicated transport track, and can use the installation track of the photovoltaic modules to transport the photovoltaic modules, thereby reducing construction costs.

[0067] In one embodiment, see Figure 2 The multiple wheels 400 include front wheels and rear wheels, and the pressure detection device 200 is provided on the front wheels and the rear wheels on the same side.

[0068] The pressure detection device 200 is set on the same side, which can directly monitor the lateral pressure on that side, and can also indirectly monitor the lateral pressure on the opposite side. It can be understood that when the side of the wheel 400 equipped with the pressure detection device 200 exerts a greater lateral pressure on the track, the wheel 400 on the opposite side exerts a smaller lateral pressure on the track on the other side; and vice versa. The pressure detection device 200 is set on the front and rear wheels on the same side, which can monitor the vehicle speed more comprehensively and accurately. The control module 500 can adjust the speed of the front and rear wheels in time according to the pressure signals of the front and rear wheels.

[0069] In another embodiment, see Figure 3 The pressure detection device 200 is provided corresponding to the two wheels 400 on the front side of the vehicle frame 100. Of course, the pressure detection device 200 can also be provided corresponding to the two wheels 400 on the rear side of the vehicle frame 100.

[0070] In another embodiment, see Figure 4 and Figure 5 The front wheels and rear wheels on opposite sides of the frame 100 are each provided with a pressure detection device 200 .

[0071] Also, see Figures 2 to 5 The multiple wheels 400 include drive wheels 410 and driven wheels 420. The drive wheels 410 can be driven by wheel hub motors or reducers. The frame 100 is provided with drive wheels 410 on opposite sides of the track widthwise. The drive wheels 410 can be located at the front or rear of the frame 100, diagonally at both the front and rear sides of the frame 100, or all wheels 400 can be configured as drive wheels 410.

[0072] In one embodiment, see Figure 6 and Figure 7 The material transport vehicle 10 further includes a weight detection device 300 mounted on the vehicle frame 100 , and the weight detection device 300 is electrically connected to the control module 500 .

[0073] When the material transport vehicle 10 is loading or unloading materials, the weight detection device 300 detects the weight change and sends this data to the control module 500. If the placed materials are overloaded, the weight detection device 300 sends a weight overload signal to the control module 500, which controls the material transport vehicle 10 to be unable to start and issues an alarm signal, thus providing the material transport vehicle 10 with a transport overload protection function, thereby preventing the material transport vehicle 10 from damaging the track due to transport overload during transportation.

[0074] In one embodiment, see Figures 2 to 5 There are multiple weight detection devices 300, at least four weight detection devices 300 are arranged at four diagonal corners of the frame 100 and below the frame 100, and the wheels 400 are arranged below the weight detection devices 300 in a one-to-one correspondence.

[0075] The wheels 400 provide support points for the weight detection device 300. By monitoring the load conditions at the four corners, the vehicle's center of gravity can be balanced, improving detection accuracy. Furthermore, the monitoring results can be used to avoid instability or overturning risks caused by uneven loading. When the vehicle frame 100 is equipped with four or more wheels 400, the number of weight detection devices 300 can correspond to the number of wheels 400.

[0076] In other embodiments, for a single track, multiple wheels 400 are arranged in a row, and multiple weight detection devices 300 are arranged in a row corresponding to the wheels 400. For a triple track, at least three wheels 400 are distributed in a triangle, and at least three weight detection devices 300 are distributed in a triangle corresponding to the wheels 400.

[0077] In one embodiment, see Figure 9 The weight detection device 300 includes a first mounting plate 310, a second mounting plate 320, a second guide shaft 340 and a second sensor 330. The first mounting plate 310 is arranged above the second mounting plate 320 and is relatively fixedly connected to the frame 100. The second sensor 330 is arranged between the first mounting plate 310 and the second mounting plate 320. One end of the second guide shaft 340 is relatively fixedly connected to the first mounting plate 310, and the other end is slidingly connected to the second mounting plate 320. The wheel 400 is rotatably arranged below the second mounting plate 320, and the rotation axis of the second mounting plate 320 and the wheel 400 are relatively fixedly arranged.

[0078] The first mounting plate 310 is disposed above the second mounting plate 320 and is relatively fixedly connected to the vehicle frame 100, providing a fixed fulcrum to ensure stable installation of the weight detection device 300. The first mounting plate 310 can be directly fixedly connected to the vehicle frame 100 by welding, or can be detachably connected to the vehicle frame 100 by screw locking or other methods. The second guide shaft 340 is used to guide the vertical movement of the second mounting plate 320. The second sensor 330 is disposed between the first mounting plate 310 and the second mounting plate 320 and is used to detect the relative displacement between the first mounting plate 310 and the second mounting plate 320, thereby calculating the load on the wheel 400.

[0079] When material is placed on the vehicle frame 100, the second mounting plate 320, supported by the wheels 400, remains stationary. The weight of the material is transmitted through the vehicle frame 100 to the first mounting plate 310. Under the load, the first mounting plate 310 moves downward along the second guide shaft 340, pressing against the second sensor 330. Simultaneously, the second guide shaft 340 and the second mounting plate 320 slide relative to each other. The second sensor 330 converts the detected weight into an electrical signal and transmits this signal to the control module 500. After receiving the electrical signal from the second sensor 330, the control module 500 processes and analyzes the signal, calculates the load on each wheel 400, and then, based on the loads on multiple wheels 400, determines the total weight of the material.

[0080] In one embodiment, see Figure 6 The material transport vehicle 10 further includes a connector 600 and a rotating shaft 700 . The connector 600 is fixedly connected to the bottom of the second mounting plate 320 and forms a receiving space. The wheel 400 is partially disposed in the receiving space and is connected to the connector 600 through the rotating shaft 700 .

[0081] The wheel 400 is connected to the connector 600 via the rotating shaft 700, allowing the wheel 400 to rotate freely within the accommodation space of the connector 600. At the same time, the wheel 400 can be fixedly connected to the second mounting plate 320 via the connector 600, thereby enabling the wheel 400 to support the weight detection device 300.

[0082] In other embodiments, the wheel 400 may be configured as a bearing, the outer ring of the bearing being capable of rolling on the track, and the inner ring of the bearing being fixedly connected to the second mounting plate 320 via a connecting rod or a connecting piece.

[0083] In one embodiment, see Figure 6 The mounting base 210 is mounted on one of the first mounting plate 310 and the second mounting plate 320 .

[0084] The mounting base 210 can be mounted on either the first mounting plate 310 or the second mounting plate 320. By mounting the mounting base 210 on either the first mounting plate 310 or the second mounting plate 320, the pressure detection device 200, the weight detection device 300, and the wheel 400 can be integrated, making the structure of the three more compact. Furthermore, the distance between the pressure detection device 200 and the wheel 400 is closer, and the detection results of the pressure detection device 200 are more accurate.

[0085] In other embodiments, the mounting base 210 may also be mounted on the frame 100 near the wheel 400 .

[0086] In one embodiment, see Figure 7 The material transport vehicle 10 also includes a guide structure 800, which includes a connecting shaft 810 and a guide wheel 820. One end of the connecting shaft 810 is connected to one of the first mounting plate 310 and the second mounting plate 320, and the other end is rotatably connected to the guide wheel 820. The guide wheel 820 is used to rotatably abut one of the side surfaces of the track distributed in its width direction.

[0087] Guide wheel 820 is connected to first mounting plate 310 or second mounting plate 320 via connecting shaft 810 and is capable of rotating freely along the side of the track. Guide wheel 820 is designed to rotatably abut one side of the track along its width, ensuring that the vehicle maintains the correct direction and position while traveling on the track, reducing lateral deviation and improving driving stability and accuracy.

[0088] In one embodiment, see Figure 2 The pressure detection device 200 is provided on the front wheel and the rear wheel on the same side, and the guide structure 800 is provided on the front wheel and the rear wheel on the other side.

[0089] In another embodiment, see Figure 3 The pressure detection device 200 is provided corresponding to the two wheels 400 on the front side of the frame 100 , and the guide structure 800 is provided corresponding to the two wheels 400 on the rear side of the frame 100 .

[0090] In one embodiment, see Figure 6 and Figure 7 The material transport vehicle 10 further includes a third mounting plate 910 and a fastener 920 . The first mounting plate 310 and the third mounting plate 910 are disposed on both sides of the vehicle frame 100 in the vertical direction and are connected by the fastener 920 .

[0091] The third mounting plate 910 is positioned above the vehicle frame 100, opposite the first mounting plate 310. Fasteners 920 are used to connect the first and third mounting plates 310, ensuring they are securely fixed to the vehicle frame 100. This allows the weight detection device 300 to be removably mounted on the vehicle frame 100, thereby flexibly adjusting the spacing between the wheels 400. By loosening the first and third mounting plates 310, 910, and adjusting the positions of the wheels 400 symmetrically based on the center of the vehicle frame 100, the wheels 400 can be safely and stably positioned on the track. This allows the material transport vehicle 10 to adapt to track spacings of varying specifications, improving its compatibility.

[0092] The above description is merely an exemplary embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structural transformation made using the contents of the present application specification and drawings under the technical concept of the present application, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present application.
