Description

Technical Field

[0001] This utility model generally relates to the field of teaching aids technology, and specifically to a frame for a single-chip microcomputer-based intelligent vehicle teaching aid. Background Technology

[0002] In existing programming courses, teachers typically use microcontroller-based intelligent vehicle teaching aids. These aids consist of a frame and a circuit board mounted on the frame, which provides a connection point for various electronic components used in teaching. Most existing circuit boards are fixed to the frame with bolts, and the distance between the circuit board and the frame is small. Users need to disassemble and reassemble the circuit board to access and install electronic components when changing teaching materials. This repeated bolt tightening and loosening of the circuit board each time causes considerable inconvenience for users. Utility Model Content

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a chassis for a single-chip microcomputer-based intelligent vehicle teaching aid.

[0004] This application provides a chassis for a microcontroller-based intelligent vehicle teaching aid, comprising:

[0005] Carrier board, used to mount circuit boards;

[0006] The base plate has two mounting seats spaced apart along a first direction on its top. Each mounting seat has a groove along one side facing each other. The groove is open at one end along a second direction, and the end of the carrier plate can enter and exit the groove through the opening. At least one opening is provided with an elastic stop mechanism, which is movably configured to switch between a stop position and a clearance position. In the stop position, the elastic stop mechanism extends into the sliding path of the carrier plate, and in the clearance position, the elastic stop mechanism exits the sliding path of the carrier plate. The first direction and the second direction are perpendicular.

[0007] Furthermore, the elastic stop mechanism includes a stop rod and an elastic element. The stop rod is movably disposed on the mounting base, and the elastic element cooperates with the stop rod to provide a spring force to the stop rod to move in the direction of the stop position.

[0008] Furthermore, the groove wall is provided with mounting holes, a stop rod is inserted into the mounting holes, an elastic element is located in the mounting holes, and the elastic element and the stop rod abut against each other.

[0009] Furthermore, the mounting hole is a stepped hole, which includes a first hole segment and a second hole segment connected together. The diameter of the second hole segment is larger than that of the first hole segment. One end of the first hole segment is located on the groove wall of the slide, and the second hole segment is located on the side of the first hole segment away from the slide. A first stepped surface is formed between the first hole segment and the second hole segment. A stop ring is provided on the outer periphery of the stop rod. The stop ring and the elastic element are both located in the second hole segment. The stop ring abuts against the first stepped surface under the pushing of the elastic element.

[0010] Furthermore, the stepped hole also includes a third hole section, which is located on the side of the second hole section away from the first hole section. The end of the third hole section away from the second hole section passes through the mounting base, and the stop bar has an extension section that extends out of the third hole section.

[0011] Furthermore, the direction of movement of the stop lever is parallel to the first direction.

[0012] Furthermore, both openings are equipped with elastic stop mechanisms.

[0013] Furthermore, the carrier plate has a rectangular frame structure.

[0014] The single-chip microcomputer intelligent vehicle teaching aid frame provided in this application has two sliding grooves spaced apart along a first direction on the top of the base plate, with one end of the sliding groove being open along a second direction. Both ends of the carrier plate enter the sliding groove through the openings. At least one of the openings is equipped with an elastic stop mechanism, which is retractably and movably configured to switch between a stop position and a clearance position. This allows the carrier plate to be slid out of the sliding groove after the elastic stop mechanism is switched to the clearance position when removing the circuit board, and the carrier plate to be slid into the sliding groove after the elastic stop mechanism is switched to the stop position when installing the circuit board. This makes the circuit board removal and installation in the teaching aid simple and convenient, and eliminates the need for bolt removal and installation, improving the convenience of circuit board removal and installation and enhancing the user experience of the single-chip microcomputer intelligent vehicle teaching aid.

[0015] Other features, objects, and advantages of this application will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings:

[0016] Figure 1 This is a schematic diagram of the structure of the frame for the microcontroller-based intelligent vehicle teaching aid provided in the embodiments of this application;

[0017] Figure 2 This is a schematic diagram of the elastic stop mechanism provided in the embodiments of this application when it is in the stop position. Detailed Implementation

[0018] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0019] Please refer to the attached document. Figure 1This application provides a frame for a microcontroller-based intelligent vehicle teaching aid, including a base plate 100 and a carrier plate 200. Wheels are mounted on the bottom of the base plate 100 to enable the intelligent vehicle to move. The carrier plate 200 is mounted on top of the base plate 100 and is used to mount a circuit board. The circuit board and the carrier plate 200 are fixedly connected by screws or snap-fit ​​connections.

[0020] The top of the base plate 100 is provided with two mounting seats 110 spaced apart along a first direction. Each mounting seat 110 has a groove 111 on one side facing each other, and the groove 111 has an opening 112 at one end along a second direction. As shown in the attached figures, the first direction is indicated by arrow A, and the second direction by arrow B. The first and second directions are perpendicular to each other and both perpendicular to the vertical direction. The two grooves 111 and the area between them form a receiving area for the carrier plate 200. Both opposite ends of the carrier plate 200 can enter and exit the grooves 111 through the openings 112, thus allowing the carrier plate 200 to enter and exit the receiving area. At least one opening 112 is provided with an elastic stop mechanism, which is retractably configured to switch between a stop position and a clearance position. In the stop position, the elastic stop mechanism extends into the sliding path of the carrier plate 200, and the carrier plate 200 located in the receiving area is fixed in the receiving area by the stopping action of the elastic stop mechanism. When in the avoidance position, the elastic stop mechanism exits the sliding path of the carrier plate 200, at which point the carrier plate 200 can enter and exit the carrier plate 200 receiving area.

[0021] In this embodiment, when the circuit board needs to be disassembled, the carrier plate 200 can be slid out of the slide groove 111 after the elastic stop mechanism is switched to the avoidance position. When the circuit board needs to be installed, the carrier plate 200 can be slid into the slide groove 111 after the elastic stop mechanism is switched to the stop position. This makes the disassembly and assembly of the circuit board in the teaching aid simple and convenient, and eliminates the need for bolt disassembly and assembly, thereby improving the convenience of the disassembly and assembly of the circuit board and enhancing the user experience of the microcontroller intelligent vehicle teaching aid.

[0022] Optionally, the carrier board 200 has a rectangular frame structure, meaning it comprises four segments connected end-to-end to form a rectangular frame structure. The cutout area in the center of the carrier board 200 exposes the bottom of the circuit board, facilitating the user's installation and removal of electronic components from the bottom of the circuit board.

[0023] In some embodiments of this application, the elastic stop mechanism includes a stop rod 121 and an elastic element 122. The stop rod 121 is movably disposed on the mounting base 110, and the elastic stop mechanism restricts the entry and exit of the carrier plate 200 through the stop rod 121. The elastic element 122 cooperates with the stop rod 121 to provide a spring force to the stop rod 121 to move towards the stop position, so that the stop rod 121 can automatically switch from the avoidance position to the stop position under the drive of the elastic element 122, reducing user operation.

[0024] Optionally, the movement direction of the stop rod 121 is parallel to the first direction. Both openings 112 are provided with elastic stop mechanisms. The elastic element 122 can be, but is not limited to, a spring.

[0025] In some embodiments of this application, the groove wall of the slide 111 is provided with a mounting hole, the stop rod 121 is inserted into the mounting hole, the elastic member 122 is located in the mounting hole, and the elastic member 122 and the stop rod 121 abut against each other.

[0026] Optionally, the mounting hole is a stepped hole, comprising a first hole segment 1131 and a second hole segment 1132 connected together. The diameter of the second hole segment 1132 is larger than the diameter of the first hole segment 1131. One end of the first hole segment 1131 is located on the groove wall of the slide groove 111, and the second hole segment 1132 is located on the side of the first hole segment 1131 away from the slide groove 111. A first stepped surface is formed between the first hole segment 1131 and the second hole segment 1132. A stop ring portion 1212 is provided on the outer periphery of the stop rod 121. The stop ring portion 1212 and the elastic member 122 are both located in the second hole segment 1132. The stop ring portion 1212 abuts against the first stepped surface under the pushing force of the elastic member 122.

[0027] Optionally, the stepped hole further includes a third hole segment 1133, which is located on the side of the second hole segment 1132 away from the first hole segment 1131 and connected to the second hole segment 1132. One end of the third hole segment 1133 away from the second hole segment 1132 passes through the mounting base 110. A second stepped surface 1134 is formed between the second hole segment 1132 and the third hole segment 1133. An elastic member 122 is sleeved on the outer periphery of the stop rod 121, with one end of the elastic member 122 away from the stop ring portion 1212 abutting against the second stepped surface 1134. The stop rod 121 has an extension segment 1211 that extends beyond the third hole segment 1133, such that the extension segment 1211 is at least partially located outside the mounting base 110, allowing the user to switch the position of the stop rod 121 by operating the extension segment 1211. The surface of the portion of the extension segment 1211 located outside the mounting base 110 may be provided with multiple protrusions to increase frictional resistance. Preferably, the first hole segment 1131 to the third hole segment 1133 are all cylindrical, and the stop bar 121 is also cylindrical and the shape of the stepped hole is compatible.
