[0002] In teaching and popular science education, in order to deepen students' understanding of the working principles and working conditions of the corresponding mechanical equipment and improve learning efficiency, relevant simulated small equipment is generally used to demonstrate the working principles and working conditions of the corresponding mechanical equipment (for example, a small water pump combined with a sprinkler, fire probe, etc. is used to simulate automatic fire extinguishing after a fire).
[0003] While existing technologies offer a wide range of mechanical simulation devices that simulate the working principles and operating conditions of corresponding equipment, there is no device that can simulate the load of a vehicle climbing different slopes. This makes it difficult for young students, especially those in the younger age groups, to intuitively understand the load and required driving torque of a vehicle climbing different slopes, hindering their ability to grasp the relevant knowledge. Therefore, it is particularly necessary to provide a display stand that is easy to use and can effectively simulate the climbing performance of a vehicle on different slopes, thereby deriving the corresponding driving torque. Utility Model Content

Students can drive the simulated vehicle along the slope through a hand-cranked winding mechanism to specifically feel the required driving torque of the vehicle at different slopes, thereby providing favorable technical support for students to master relevant knowledge.

[0007] Furthermore, the length and width of the slope plate are smaller than the inner diameter of the booth body, and there is a certain distance between the two ends of the slope plate and one end of the inner end of the booth body and the pulley.
[0008] Furthermore, a plurality of counterweights are installed in the simulated vehicle.

[0015] Figure 1 、 2 As shown in , 3, a display stand device for demonstrating vehicle climbing driving torque for teaching purposes includes a display stand body 1 with an open upper end and a closed lower end and side ends, a simulated vehicle 2, an electric telescopic rod M, a rectangular slope plate 4, a pulley 5, a power module D1, a tension sensor D2, a liquid crystal voltage display meter V, a power switch S, a handle 3, a linkage rod 7 and a winding wheel 8, and a wire rope 9; the front and rear parts of the left end of the slope plate 4 (lower on the left and higher on the right) are hingedly installed at the front and rear parts of the inner left end of the display stand body through a first hinge seat, and the electric telescopic rod M is a rectangular slope plate 4, a pulley 5, a power module D1, a tension sensor D2, a liquid crystal voltage display meter V, a power switch S, a handle 3, a linkage rod 7, ... The lower end of the cylinder of the movable push rod M is hingedly installed in the lower middle part of the booth body 1 through the second hinge seat, and the upper end of the movable rod of the electric push rod M is hingedly installed in the lower middle part of the slope plate 4 through the third hinge seat; there are two pulleys, and the two pulleys 5 are respectively installed at the upper and lower ends of the right middle part of the booth body 1 through the pulley frame through the screw nut. A support platform 10 with a height lower than the height of the booth body is installed on the right side of the front end of the booth body 1 through the screw nut. A bearing seat 11 is installed in the middle of the rear upper end of the support platform 10 through the screw nut. The middle of the winding wheel 8 is welded to the rear end of the linkage rod 7 (the winding wheel 8 has a groove distributed in an annular manner as a winding groove). One end of the wire rope 9 is welded to the winding groove of the winding wheel 8. The other end of the wire rope 9 passes through the right end of the slide groove of the two pulleys 5 and is connected to one end of the tension sensor D2 (there is a fixed ring in the middle of this place to facilitate the connection of the wire rope 9). Together, the other end of the tension sensor D2 (there is also a fixed ring in the middle to facilitate the connection of another steel wire rope 9) and the middle of the front end of the simulated vehicle 1 are connected together through another steel wire rope 9. The simulated vehicle 2 is placed on the middle of the left end of the slope plate 4, and the rear middle part of the handle 3 is welded to the front end of the linkage rod 7 and an operating lever 12 is longitudinally welded to one side of the front end of the handle; the power module D1, the liquid crystal voltage display meter V, and the power switch S are installed on the circuit board inside the electric control box 13, and the electric control box 13 is installed at the front end of the support platform 10.
[0016] Figure 1 、 2As shown in Figures 3 and 4, the length and width of the ramp plate 4 are smaller than the inner diameter of the booth body 1. The left end of the ramp plate 4 is spaced a certain distance (2 cm) from the inner left end of the booth body 1, and the right end of the ramp plate 4 is spaced a certain distance (3 cm) from the pulley 5. The simulated vehicle 1 contains multiple counterweights 14. The electric telescopic rod M is a finished reciprocating electric actuator. The power module D1 is a finished AC 220V to DC 12V switching power module with an output power of 500W. The power switch S is a toggle power switch with two power input terminals (pins 1 and 2) and two power output terminals (pins 3 and 4, and pins 5 and 6).
[0017] Figure 1 、 2 As shown in Figures 3 and 4, the power input terminals 1 and 2 of the power module D1 are connected to the two poles of the AC power supply via wires, respectively. The power output terminals 3 and 4 of the power module D1 are connected to the power input terminals 1 and 2 of the power switch S, and the power input terminals 1 and 2 of the tension sensor D2 are connected via wires, respectively. The signal output terminals 3 and 2 of the tension sensor D2 (the wire connected to it has a sufficient length to enter the electric control box through the opening between the booth body and the support platform. The display interface of the LCD voltage display meter and the operating handle of the power switch are located at the front opening of the electric control box and outside the opening, respectively) are connected to the power input terminal of the LCD voltage display meter V via wires, respectively. The two power output terminals 3, 4 and 5, 6 of the power switch S are connected to the positive and negative, and negative and positive power input terminals of the electric telescopic pole M, respectively, via wires.
[0018] Figure 1 、 2 As shown in Figure 3, after the 220V AC power enters the power input terminal of the power module D1, the power output terminal of the power module D1 outputs a stable DC 12V power supply which enters the power input terminal of the power switch S and the tension sensor D2, and the power switch S and the tension sensor D2 are powered on and work. In this new application, students or other administrators can control the slope of the slope plate 4 using the power switch S. When the power switch S is toggled left or right, pins 1 and 2 of the power switch S are connected to pins 3 and 4 or pins 5 and 6, respectively, so that the positive and negative or negative-positive poles of the electric push rod M are energized and operated. When the positive and negative poles of the electric push rod M are energized, its movable rod pushes the slope plate 4 upward along the hinge point, thereby increasing the height of the right end of the slope plate 4 and increasing the subsequent simulation and the climbing driving torque and vehicle load. When the negative and positive poles of the electric push rod M are energized, its movable rod pushes the slope plate 4 downward along the hinge point, thereby decreasing the height of the right end of the slope plate 4 and decreasing the subsequent simulation and the climbing driving torque and vehicle load. By placing different numbers of counterweights 14 in the simulated vehicle compartment, the climbing driving torque and vehicle load of the simulated vehicle under different load conditions can be simulated.
[0019] Figure 1 、2 As shown in Figure 3, during application, students, teachers or exhibition hall staff turn the operating lever 12 by hand, and then the handle 3 drives the winding wheel 8 to rotate, and the winding wheel 8 winds up the wire rope 9 and contracts, so that the wire rope 9 will pull the simulated vehicle 2 (for example, with a counterweight of 22.5KG) to move to the upper right along the slope plate 4. While the vehicle 2 moves upward, the tension sensor D2 displays different tension value data through the voltmeter V as the vehicle moves upward toward the slope plate (the higher the slope, the greater the tension value data displayed). The relevant personnel turn the handle by hand and drive the vehicle to move to the upper right along the slope plate 4 (because the slope plate is a planar structure, the simulated vehicle can stably move up or down the slope plate). The gravity data generated by the vehicle moving along the slope plate to the lower left will directly act on the human hand. The higher the slope of the slope plate, the greater the gravity, and vice versa. Through the above, the utility model can control the height of the slope board through the power switch and the electric telescopic rod, and can simulate the climbing performance of the vehicle under different slope load conditions by loading different counterweights into the cargo box of the simulated vehicle (since the upper end of the booth body 1 is an open structure, teachers and the like can conveniently load different counterweights into the cargo box of the simulated vehicle through the upper end of the booth body 1). Students and the like drive the vehicle up the slope board by winding the wire rope through the hand crank, and can intuitively feel the different slopes and loads and the climbing torque required by the vehicle, and can display specific tension data through the dynamometer and voltmeter (the larger the value displayed on the voltmeter, the greater the climbing load of the vehicle and the greater the required driving force, and vice versa), thereby providing favorable technical support for students to master relevant knowledge. Tension sensor D2 is a small FA114 model. It has two power inputs and a signal output. During operation, the signal output dynamically changes with the tension. The LCD display is a PVAH4 24V DC voltmeter. The voltage output from the tension sensor, which varies with load, is displayed on the display screen. A higher voltage indicates a greater climbing load and required driving torque, and vice versa. After the test, the operator removes handle 3. Under the influence of the slope of grade plate 4 and the weight of vehicle 2, the vehicle slides downward and leftward along grade plate 4 to its stop (the handle and winding wheel rotate in opposite directions to release the wire rope), ready for the next use.
