Description

Technical Field

[0001] This utility model relates to the field of teaching equipment technology, and in particular to a teaching model of automobile chassis structure. Background Technology

[0002] In automotive engineering education, automotive chassis structure teaching models serve as core teaching tools for intuitively demonstrating chassis construction and transmission principles, and are widely used in vocational schools, training institutions, and corporate technical training. With the diversification of teaching scenarios and the differentiation of learners, higher demands are placed on the flexibility, applicability, and ease of operation of teaching models. Optimizing model structures to accommodate the observation needs of students of different heights, while simplifying component assembly and disassembly processes, has become a key technical direction for improving teaching efficiency and learning experience.

[0003] Currently, most automotive chassis structure teaching models use a fixed-height display platform, with chassis components statically assembled and fixed to a support. Their mechanical structure typically consists of a welded or bolted metal frame, with wheels, suspension, and other components secured in pre-set positions using clips or glue. During instruction, students primarily learn by observing the model from multiple angles, in conjunction with the teacher's explanations. This design relies on a fixed perspective, making it difficult to meet the observation needs of learners of different heights, and it lacks dynamic adjustment capabilities, failing to simulate the movement of components under real-world conditions.

[0004] Currently, most automotive chassis structure teaching models use fixed-height display platforms, fixing chassis components to supports through static assembly. However, traditional fixed-height teaching models have significant limitations. Due to differences in eye level among students of different heights, fixed-height display platforms often make it difficult for some students to clearly observe chassis details, especially low-lying components. This not only affects students' understanding of complex chassis structures but also reduces teaching interactivity and participation. Furthermore, because the model height cannot be adjusted, teachers must frequently adjust their own positioning or use auxiliary tools during demonstrations, resulting in a cumbersome teaching process and hindering teaching efficiency. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a teaching model of automobile chassis structure, which aims to improve the problem that traditional fixed-height teaching models have obvious limitations and that students of different heights have different line-of-sight heights.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a teaching model of automobile chassis structure, including a model body, a placement plate attached to the lower surface of the model body, a wheel slidably connected to the inner wall of the placement plate, and an adjustment component provided on the lower surface of the placement plate;

[0007] The adjustment assembly includes a telescopic rod, the upper surface of which is fixedly connected to the lower surface of the placement plate.

A connecting rod is rotatably connected to the inner wall of the support leg. A handle is fixedly connected to one end of the connecting rod, and a gear is fixedly connected to the other end of the connecting rod. A pin is slidably connected inside the support leg.

[0008] Furthermore, a locking block is slidably connected to the inner wall of the wheel, a moving block is fixedly connected to the lower surface of the locking block, a two-way lead screw is threadedly connected to the inner wall of the moving block, a guide rod is slidably connected to the inner wall of the moving block, a knob is fixedly connected to one end of the two-way lead screw, and a fixing plate is fixedly connected to the lower surface of the placement plate.

[0009] Furthermore, the outer wall of the locking block is slidably connected to the inner wall of the placement plate, and the locking block is used to fix the wheel.

[0010] Furthermore, the outer wall of the movable block is slidably connected to the inner wall of the fixed plate, and the movable block is used to drive the card block to move.

[0011] Furthermore, both ends of the guide rod are fixedly connected to the inner wall of the fixed plate, and the guide rod is used to guide the movement of the moving block.

[0012] Furthermore, the knob is located on the outer wall of the fixed plate, and the knob is used to drive the bidirectional lead screw to rotate.

[0013] Furthermore, the outer wall of the gear is rotatably connected to the inside of the support leg, and the gear is used to drive the telescopic rod to move up and down.

[0014] Furthermore, the handle is disposed on the outer wall of the support leg, and the handle is used to drive the gear to rotate.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, when using the teaching model, the pin is pulled out, the handle is turned to drive the connecting rod and gear, and the telescopic rod is moved through the gear and rack transmission to realize the height adjustment of the placement board.

[0017] 2. In this utility model, the wheel is inserted into the slot of the placement plate, and the knob is turned to drive the two-way lead screw, which drives the guide rod to make the locking block lock into the inner wall of the wheel for fixation; the locking is released by turning the knob in the opposite direction, which achieves the effect of quickly fixing and disassembling the wheel, facilitating the replacement of teaching parts and enhancing the practicality of the model.

[0025] 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.

[0026] Reference Figures 1-4 An embodiment of this utility model provides a teaching model of automobile chassis structure, including a model body 2, a placement plate 3 attached to the lower surface of the model body 2 for supporting teaching components such as wheels 4, the height of which is adjustable, providing a suitable observation platform for teaching demonstrations, and students and teachers of different heights can clearly observe the details of the model by adjusting the height of the placement plate 3, the wheels 4 are slidably connected to the inner wall of the placement plate 3, and an adjustment component is provided on the lower surface of the placement plate 3.

[0027] The adjustment assembly includes a telescopic rod 5, which is directly connected to the placement plate 3. Driven by a rack 6, it extends and retracts to change the vertical height of the placement plate 3, accommodating the observation needs of people of different heights. The upper surface of the telescopic rod 5 is fixedly connected to the lower surface of the placement plate 3. A rack 6 is fixedly connected to the outer wall of the telescopic rod 5. A support leg 1 is slidably connected to the outer wall of the telescopic rod 5. A connecting rod 8 is rotatably connected to the inner wall of the support leg 1. A handle 9 is fixedly connected to one end of the connecting rod 8, and a gear 7 is fixedly connected to the other end. A pin 10 is slidably connected inside the support leg 1 to lock the connecting rod 8 and fix the height of the placement plate 3. When pulled out, the limit is released, allowing the connecting rod 8 to rotate and adjust the height; when inserted, it securely locks the placement plate 3 in the target position, preventing height changes during teaching.

[0028] Specifically, when using the teaching model of the car chassis structure, the first step is to pull out the pin 10 from its fixed position to release the restriction on the connecting rod 8. Then, turn the handle 9. The rotational power of the handle 9 will be transmitted to the connecting rod 8, causing it to start rotating. After the connecting rod 8 rotates, it will drive the gear 7 connected to it to rotate together. Since the gear 7 and the rack 6 mesh with each other, and the rack 6 is fixedly connected to the telescopic rod 5, the rotation of the gear 7 will drive the rack 6 to move horizontally, thereby driving the telescopic rod 5 to extend and retract. Finally, the height of the placement plate 3 can be flexibly adjusted to meet the viewing needs of people of different heights.

[0029] Reference Figure 1 and Figure 5 A locking block 11 is slidably connected to the inner wall of wheel 4 and hinged to guide rod 15. Driven by guide rod 15, it engages or disengages from the groove in the inner wall of wheel 4, achieving secure fixing and quick disassembly of wheel 4, ensuring stability and convenience during teaching demonstrations. A movable block 16 is fixedly connected to the lower surface of locking block 11. A two-way lead screw 14 is threadedly connected to the inner wall of movable block 16 and connected to knob 13. Through its own rotation, it converts rotational motion into linear motion of guide rod 15. Its two-way thread design allows for bidirectional movement of guide rod 15, controlling the extension and retraction of locking block 11. Guide rod 15 is slidably connected to the inner wall of movable block 16, and knob 14 is fixedly connected to one end of the two-way lead screw 14. 3. A fixed plate 12 is fixedly connected to the lower surface of the placement plate 3. The outer wall of the locking block 11 is slidably connected to the inner wall of the placement plate 3. The locking block 11 is used to fix the wheel 4. The outer wall of the moving block 16 is slidably connected to the inner wall of the fixed plate 12. The moving block 16 is used to drive the locking block 11 to move. Both ends of the guide rod 15 are fixedly connected to the inner wall of the fixed plate 12. The guide rod 15 is used to guide the movement of the moving block 16. The knob 13 is set on the outer wall of the fixed plate 12. The knob 13 is used to drive the bidirectional lead screw 14 to rotate. The outer wall of the gear 7 is rotatably connected to the inside of the support leg 1. The gear 7 is used to drive the telescopic rod 5 to move up and down. The handle 9 is set on the outer wall of the support leg 1. The handle 9 is used to drive the gear 7 to rotate.

[0030] Specifically, during demonstration and teaching, first align wheel 4 above the placement plate 3 and insert it into the internal slot for initial positioning. Then, rotate knob 13, which drives the bidirectional lead screw 14 to rotate synchronously. Since guide rod 15 is threadedly engaged with bidirectional lead screw 14, the rotation of the lead screw drives guide rod 15 to move along the outer wall. During the movement of guide rod 15, it pushes the locking block 11 forward until it is precisely locked into the groove on the inner wall of wheel 4, completing the secure fixation. When disassembling, rotate knob 13 in the opposite direction, bidirectional lead screw 14 reverses, and guide rod 15 drives locking block 11 to retract backward, detaching from the inner wall of wheel 4, easily achieving disassembly. The operation is convenient and efficient.

[0031] Working principle: When the teaching model of the car chassis structure is needed, first pull out the pin 10, and then turn the handle 9 to drive the connecting rod 8 to rotate. The rotation of the connecting rod 8 will drive the gear 7 to rotate. Because the rack 6 and the telescopic rod 5 are fixedly connected, and the rack 6 and the gear 7 are meshed, the rotation of the gear 7 will drive the rack 6 and the telescopic rod 5 to move synchronously. This makes it convenient for users to adjust the height of the placement plate 3, so as to accommodate students and teachers of different heights for observation and learning.

[0032] Furthermore, when the wheel 4 is placed on the placement plate 3, it is inserted into the slot inside the placement plate 3. By turning the knob 13, the double-acting screw 14 can be rotated together, causing the guide rod 15 to move along the outer wall of the double-acting screw 14. The movement of the guide rod 15 will cause the locking block 11 to be inserted into the inner wall of the wheel 4, thereby fixing the wheel 4. When it is necessary to remove the wheel 4, simply turn the knob 13 in the opposite direction to make the locking block 11 disengage from the inner wall of the wheel 4, thus releasing the fixation of the wheel 4.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
