Detailed implementation manners

[0033] The following details the embodiments of the present utility model. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0034] The driving member 310 can be driven by a single part or by a component composed of multiple parts. The vehicle body 1 is provided with a driving structure capable of driving the crawler 2. The vehicle body 1 can be a tank model, a transport vehicle model, a tractor model, etc. That is, the present application does not limit the type of the vehicle body 1, and as long as the vehicle body 1 has a crawler 2 structure, this solution can be used.

[0035] Such as Figure 1 - Figure 2As shown in the figure, a track 2 adjusting structure of a toy car includes a vehicle body 1, a track 2, and a tension adjusting structure 3. The track 2 is sleeved on the vehicle body 1. The tension adjusting structure 3 includes a driving member 310 and a pressing member 320. The driving member 310 is connected to the vehicle body 1 and drives the pressing member 320 to move. The pressing member 320 is connected to the track 2. Multiple driving wheels are provided on the vehicle body 1, and the track 2 is sleeved on the driving wheels. Specifically, when the pressing member 320 moves outward from the vehicle body 1, the track 2 is tightened; when the pressing member 320 moves inward from the vehicle body 1, the track 2 is loosened. Since the tracks 2 of toy cars are mostly made of elastic materials or are link-type, during use, due to external forces and the nature of the materials themselves, elastic tracks are prone to losing their elasticity and becoming longer, and the link pins and bushings of link-type tracks will have a certain amount of wear during normal operation, resulting in a decrease in the track tension. Therefore, the track 2 needs to be adjusted frequently. And some users, in order to better simulate the state of real tracks 2, need to adjust the track 2 repeatedly. In this application, through the driving member 310, the pressing member 320 can be driven to approach or move away from the track 2, thereby realizing the adjustment of the tightness of the track 2. And the driving member 310 passes through the vehicle body 1, and a corresponding adjusting portion 311 is provided on the driving member 310. The adjusting portion 311 protrudes outside the vehicle body 1. Therefore, the driving member 310 can be directly adjusted outside the vehicle body 1 through the adjusting portion 311, so there is no need to disassemble the vehicle body 1 anymore, which is more convenient and practical, easy to operate, and has a simple and compact structure, facilitating production and assembly.

[0036] In this solution, the movement of the pressing member 320 can be rotation around an axis, but it can also be linear movement in the longitudinal and transverse directions, or up / down or left / right swinging around a base point, etc. In this solution, the tension adjusting structure 3 is arranged inside the inner ring of the track 2 and the pressing member 320 abuts against the inner side wall of the track 2. However, in other embodiments, the tension adjusting structure 3 can also be arranged on the outer ring of the track 2, and the pressing member 320 can also abut against the outer side wall of the track 2. In other words, it should be understood that the pressing member 320 generates a certain pressing force on the track 2, and enables the track 2 to generate sufficient tension with other driving wheels for driving.

[0037] Among them, as Figure 3 shown, the pressing member 320 includes a gear member 321 and a pressing wheel 322 connected to the gear member 321. The gear member 321 is meshed and connected with the meshing portion 312. The gear member 321 drives the pressing wheel 322 to move, and the pressing wheel 322 is connected to the track 2. Specifically, a gear structure is provided on the gear member 321, and the gear structure is meshed and connected with the meshing portion 312. When the meshing portion 312 moves, it will drive the gear structure that cooperates with it, and then drive the gear member 321 to move. And because the pressing wheel 322 is connected to the gear member 321, the position adjustment of the pressing wheel 322 and the track 2 is realized, and the adjustment of the tightness of the track 2 is realized.

[0038] In one embodiment, as Figure 4 shown, the gear member 321 includes a main body 3211, a connecting column 3212, a rotating column 3213 and a transmission gear 3214. One end of the main body 3211 is connected to the connecting column 3212, and the other end is connected to the rotating column 3213. The end of the connecting column 3212 away from the main body 3211 is connected to the vehicle body 1. At least one of the axes of the main body 3211, the connecting column 3212 and the rotating column 3213 is eccentric to the other axes; the transmission gear 3214 is connected to the connecting column 3212 and meshes with the meshing portion 312. The end of the rotating column 3213 away from the main body 3211 is connected to the pressing wheel 322. Specifically, the gear member 321 is the rotating column 3213, the main body 3211 and the connecting column 3212 from top to bottom; and the connecting column 3212 and the main body 3211 are on the same axis, while the rotating column 3213 is eccentrically connected to the main body 3211 (that is, the connecting column 3212 is arranged at the center of the lower end of the main body 3211, and the rotating column 3213 is arranged on one side of the upper end of the main body 3211). The transmission gear 3214 passes through the connecting column 3212 and is fixedly connected to the connecting column 3212. When the meshing portion 312 drives the transmission gear 3214 to rotate, it will drive the connecting column 3212 to rotate together, and then drive the main body 3211 to rotate. And because there is an axis gap between the rotating column 3213 and the main body 3211, the relative rotation range of the rotating column 3213 becomes larger, so as to realize the position adjustment between the pressing wheel 322 connected thereto and the crawler 2, that is, the closer the pressing wheel 322 is to the outside of the vehicle body 1, the greater the pressing force on the crawler 2, and the adjustment of the tension force is realized. At the same time, by means of eccentric connection, the occupied space of the adjustment structure can be reduced, avoiding occupying too much space of the vehicle body, so there is no need to interfere with the vehicle body too much.

[0039] In one embodiment, the main body 3211 is fixedly connected to the connecting column 3212, and the transmission gear 3214 passes through the connecting column 3212 and is detachably connected to the connecting column 3212. Specifically, the main body 3211 and the connecting column 3212 are integrally formed. The transmission gear 3214 passes through the connecting column 3212, and the cross-section of the connection between the transmission gear 3214 and the connecting column 3212 is a regular polygon. The integral formation of the main body 3211 and the connecting column 3212 can strengthen the strength of the connecting column 3212. Secondly, a prism is provided on the connecting column 3212, and a through hole matching the prism is provided on the transmission gear 3214. The transmission gear 3214 passes through the prism, and the through hole is sleeved outside the prism. The design of the prism can make the connection between the transmission gear 3214 and the connecting column 3212 more precise, prevent misalignment from occurring, and have a better transmission effect. The transmission gear 3214 and the connecting column 3212 can be an interference fit relying on friction, or the transmission gear 3214 can be limited between the end face of the prism and the wall surface of the vehicle body 1, or can be fixed by means of screws, etc. The present application does not limit this here.

[0040] Further, the transmission column can also be integrally formed with the main body 3211 (i.e., the main body 3211, the connecting column 3212, and the transmission column are all integrally formed), or can be detachably connected to the main body 3211.

[0041] In one embodiment, as Figure 5 shown, the transmission gear 3214 passes through the connecting column 3212 and is fixedly connected to the connecting column 3212, and the connecting column 3212 is detachably connected to the main body 3211. Specifically, the transmission gear 3214 is integrally formed with the connecting column 3212, the connecting column 3212 is connected to the main body 3211, and the cross-section at the connection between the connecting column 3212 and the main body 3211 is a regular polygon, that is, a prism is provided at one end of the connecting column 3212 close to the main body 3211, and a through hole matching the prism is provided on the main body 3211. The connecting column 3212 passes through the main body 3211 and the through hole is sleeved outside the prism. This solution designs the connecting column 3212 and the main body 3211 to be detachably connected, which is convenient for assembly during production and processing, and is also convenient for disassembly during later maintenance, and the structure is simpler. The connecting column 3212 and the main body 3211 can be in a transition fit relying on friction, or can be connected by means of screws, etc., and the present application does not limit this here.

[0042] In one embodiment, as Figure 6 shown, the transmission gear 3214 passes through the connecting column 3212 and is detachably connected to the connecting column 3212, and the connecting column 3212 is detachably connected to the main body 3211. Specifically, the transmission gear 3214, the connecting column 3212, and the main body 3211 are all detachably connected, and the cross-section at the connection is a regular polygon. In this solution, each component is detachable, which is more convenient for daily maintenance, can directly replace damaged components, and reduces maintenance effort and cost.

[0043] Similarly, the connection between the rotating column 3213 and the main body 3211 can be integrated or can be detachably connected, and will not be elaborated here.

[0044] In one embodiment, the gear member 321 includes a main body 3211, a rotating column 3213, and a transmission gear 3214. One end of the main body 3211 is fixedly connected to the transmission gear 3214, the other end is connected to the rotating column 3213, the transmission gear 3214 meshes with the meshing portion 312, and one end of the rotating column 3213 away from the main body 3211 is connected to the pressing wheel 322. Specifically, the main body 3211 is connected to the transmission gear 3214 to form a rack structure, and the main body 3211 is slidably connected to the vehicle body 1. When the meshing portion 312 drives the transmission gear 3214 to move, the main body 3211 will move linearly accordingly, and then drive the pressing wheel 322 to move outward or inward of the vehicle body 1 to achieve the adjustment function, and the adjustment accuracy is higher and the transmission speed is faster.

[0045] In one embodiment, as Figure 7 shown, the driving member 310 includes an adjusting portion 311 and an engaging portion 312. The engaging portion 312 is connected to the vehicle body 1. The adjusting portion 311 is connected to the engaging portion 312 and is disposed outside the vehicle body 1. The engaging portion 312 is engaged with the pressing member 320 and drives the pressing member 320 to move. The engaging portion 312 is provided with a gear structure, and the pressing member 320 is provided with a gear structure matching the engaging portion 312, and the two are engaged with each other. Therefore, when the engaging portion 312 moves, a driving force will be generated on the pressing member 320 and the pressing member 320 will be driven to move. The adjusting portion 311 has an adjustable function and can be adjusted directly outside the vehicle body 1 or through the vehicle body 1 without disassembling the vehicle body 1. Specifically, the adjusting portion 311 passes through the vehicle body 1 and is disposed outside the vehicle body 1, so the adjusting portion 311 can be directly operated.

[0046] Specifically, in this solution, the engaging portion 312 is a worm, and the adjusting portion 311 is a groove provided at one end of the worm facing the outside of the vehicle body 1. Among them, the two ends of the engaging portion 312 in this solution are shaft portions, and the middle portion is a spiral tooth; the vehicle body 1 suspends the shaft portions at both ends, so that the driving member 310 can rotate. The spiral tooth in the middle is connected to the transmission gear 3214. When the groove is adjusted, the worm will be driven to rotate, and then the transmission gear 3214 will be driven to move. And the cooperation of the spiral teeth can effectively prevent the gear from rotating back, avoiding the situation that the pressing wheel 322 is forced to rotate back when the toy car is running, and ensuring the stable and effective structure.

[0047] Further, the shape of the groove is a hexagonal groove, which can be adjusted in cooperation with a hexagonal wrench; it can also be a "-" shaped or a "+" shaped groove, which can be adjusted in cooperation with a screwdriver. The present application does not limit the shape of the groove here.

[0048] In one embodiment, as Figure 8 shown, in this solution, the engaging portion 312 is a worm, and the adjusting portion 311 is a convex block provided at one end of the worm facing the outside of the vehicle body 1. Specifically, the adjusting portion 311 is a protrusion connected to the end face of the worm. The shape of the protrusion can be hexagonal, which can be adjusted in cooperation with a wrench; it can also be a protruding handle, and the handle can be directly clamped for adjustment. The present application does not limit the shape of the convex block here.

[0049] In one embodiment, in combination with Figure 2 、 Figure 7 and Figure 9As shown, the vehicle body 1 is provided with an adjustment cavity 100. The driving member 310 is located within the adjustment cavity 100, and the pressing member 320 passes through the adjustment cavity 100. In this solution, the vehicle body 1 is provided with an adjustment cavity. Specifically, the vehicle body 1 is provided with a placement groove, and a convex member is arranged within the groove. This convex member raises the driving member 310 (i.e., the shaft portions at both ends of the worm) to a suspended state, providing space for the rotation of the driving member 310. In addition, the vehicle body 1 is further provided with a cover plate, which is configured on the adjustment cavity and forms the adjustment cavity 100 with the adjustment cavity. Moreover, the cover plate and the convex member can also cooperate to limit the driving member 310, preventing it from shifting.

[0050] Secondly, the pressing member 320 passes through the cavity. Specifically, the connecting column 3212 passes through the cover plate, and the transmission gear 3214 is also located within the cavity. This solution can accommodate the adjustment structure, preventing the structure from being exposed outside the vehicle body 1 and further improving the adjustment accuracy of the structure.

[0051] Furthermore, the adjustment cavity 100 is provided with a limiting block 110, and the main body 3211 is provided with a clamping member 3211a. The limiting block 110 abuts against the clamping member 3211a. The limiting structure can prevent the pressing wheel 322 from being adjusted beyond the limit, directly distinguishing the maximum and minimum adjustment ranges, which is convenient for adjustment.

[0052] The above-disclosed are only one or more preferred embodiments of the present application, and the scope of rights of the present application cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
