Description

Technical Field

[0001] The present invention relates to the technical field of model cars, and in particular to a multi-angle adjustment structure of a transfer case and a transmission. Background Art

[0002] A car model is a scale model that is crafted to exacting proportions, faithfully reproducing the shape, structure, color, and even interior components of a real car. To faithfully recreate a real car, model makers will not modify or exaggerate the prototype's appearance, nor will they create a car out of thin air. While many toy cars may resemble real cars, manufacturers often make arbitrary modifications based on customer preferences and production technology limitations, leaving considerable room for arbitrariness. Toy designers can also unleash their imagination to create cars that don't exist in the real world, but this kind of imagination is not permitted with car models. Beyond the overall appearance, car models must also be highly realistic in detail. Often, a model consists of hundreds or even more parts, each a scaled-down version of a corresponding component in the original car. The more parts a model has and the finer the detailing, the higher the craftsmanship. However, toy cars fall far short of the level of detail typically found in car models, with many details omitted or made from the same material. Car models, because of their authentic reproduction of the key features of the original car and their meticulous craftsmanship, embody automotive culture and hold great collectible value.

[0003] Nowadays, most car models have been authorized by real car manufacturers, and their appearance is almost the same as that of the real car, with a very high degree of simulation. However, the engine assembly inside the car model will be different from that of the real car. Because some car models on the market use electric motors as the main power output, manufacturers will design the powertrain to adapt to the motor according to actual conditions. Among the imitated models, some are two-wheel drive models and some are four-wheel drive models. At the same time, in the four-wheel drive models, it is necessary to set the angle between the transfer case and the gearbox according to the overall structure of the four-wheel drive model, and design an overall protective shell according to the different angles between the transfer case and the gearbox. Different engine assembly protective shells must be designed and produced for each four-wheel drive model, which consumes a lot of human resources and production costs and reduces production efficiency.

[0036] Reference below Figures 1 to 5 The angle adjustment structure of the transfer case 300 and the transmission case 200 according to an embodiment of the present invention is described.

[0037] like Figures 1 to 5 As shown, the multi-angle adjustment structure of the transfer case and the transmission according to an embodiment of the present invention includes: a transmission 200 and a transfer case 300 .

[0038] The gearbox 200 is connected to the drive device 100, and the gearbox 200 includes an output shaft 210 for providing power transmission. One end of the output shaft 210 is connected to the drive device 100 of the model car; the transfer case 300 is rotatably connected to the gearbox 200, and the transfer case 300 can be rotatably connected to the gearbox 200 around the axis of the output shaft 210. The transfer case 300 is provided with a transmission output end 310 and a transfer output end 320 for transmitting the power of the output shaft 210 to the differential. The transmission output end 310 is located in the extension direction of the output shaft 210, and the transfer output end 320 can rotate around the axis of the output shaft 210 as the transfer case 300 rotates.

[0039] For example, Figures 1 to 5As shown, the drive device 100 is mainly used to provide power output, and the gearbox 200 can be connected to the drive device 100 of the model car. The gearbox 200 may include an output shaft 210 for transmitting the power on the drive device 100. One end of the output shaft 210 can be connected to the drive device 100, and the drive device 100 can drive the output shaft 210 to rotate to realize power transmission. The transfer case 300 is rotatably connected to the gearbox 200. The transfer case 300 can be rotatably connected to the gearbox 200 around the axis of the output shaft 210. The transfer case 300 can be provided with a transmission output end 310 and a transfer output end 320 for transmitting the power of the output shaft 210 to the differential. The transmission output end 310 is located in the extension direction of the output shaft 210, and the transfer output end 320 can rotate around the axial direction of the output shaft 210 as the transfer case 300 rotates.

[0040] Among them, the transfer case 300 and the gearbox 200 can achieve 360° rotation. In this embodiment, the power of the transmission output end 310 is transmitted to the differential of the rear axle, and the power of the transfer output end 320 is transmitted to the differential of the front axle. When the transfer case 300 is working, the power on the output shaft 210 can be simultaneously transmitted to the differential of the front axle to realize the four-wheel drive function.

[0041] Specifically, by rotatably connecting the transfer case 300 with the gearbox 200, the power in the drive device 100 can be transmitted to the transmission output end 310 through the output shaft 210. At the same time, the transfer case 300 can be rotated on the gearbox 200, so that the transfer output end 320 can rotate around the axis of the output shaft 210 as the transfer case 300 rotates. The staff can adjust the position of the transfer output end 320 according to the structure of different vehicle models, so that it can be adapted and installed on multiple vehicle models, reducing the waste of human resources and production costs, and greatly improving the production efficiency of model cars.

[0042] In some embodiments of the present invention, a rotation connection column 330 is protruded from the housing of the transfer case 300, and a rotation connection groove 220 is provided on the housing of the transmission case 200. The rotation connection column 330 is rotatably engaged in the rotation connection groove 220. For example, Figures 2 to 4 and Figure 6 As shown, in this embodiment, Figure 6The circumferential surface of the rotating connecting column 330 is concavely provided with an annular groove 332, and the inner wall surface of the rotating connecting groove 220 is convexly provided with an annular clamping portion 222. When the rotating connecting column 330 on the transfer case 300 is engaged with the rotating connecting groove 220, the annular clamping portion 222 will be engaged with the annular groove 332, so that the rotating connecting column 330 will not be separated from the rotating connecting groove 220, thereby making the installation of the transfer case 300 and the gearbox 200 more stable. At the same time, the axis of the rotating connecting column 330 and the axis of the rotating connecting groove 220 are collinear with each other, and are also collinear with the axis of the output shaft 210, so that when the transfer case 300 rotates on the gearbox 200, it will not affect the rotation of the internal output shaft 210.

[0043] In some embodiments of the present invention, a snap-fitting groove 331 is concavely provided on the peripheral side surface of the rotating connecting column 330, and a snap-fitting rib 221 adapted to the snap-fitting groove 331 is convexly provided on the inner wall surface of the rotating connecting groove 220, and the snap-fitting rib 221 is snap-fitted into the snap-fitting groove 331. For example, Figures 2 to 4 As shown, in this embodiment, a plurality of engaging grooves 331 are concavely provided on the peripheral side surface of the rotating connecting column 330, and the plurality of engaging grooves 331 are evenly distributed on the rotating connecting column 330. Three engaging ribs 221 are provided on the inner wall surface of the rotating connecting groove 220. The spacing between the three engaging ribs 221 is the same as the spacing between the engaging grooves 331. After the staff installs the rotating connecting column 330 in the rotating connecting groove 220, the engaging ribs 221 will be engaged in the engaging grooves 331, which can fix the relative angle between the transfer case 300 and the gearbox 200. Since the shell of the transfer case 300 and the gearbox are The shell of 200 is made of plastic material, so when the staff rotates the transfer case 300 through external force, slight plastic deformation will occur between the engaging ribs 221 and the engaging grooves 331, so that the engaging ribs 221 in the transfer case 300 will rotate along the inner wall surface of the rotating connecting groove 220 and engage into the adjacent engaging grooves 331, thereby changing the angle between the transfer case 300 and the gearbox 200. By adopting the engaging method of the engaging ribs 221 and the engaging grooves 331, the staff can very conveniently adjust the angle between the transfer case 300 and the gearbox 200, thereby improving production efficiency.

[0044] In some embodiments of the present invention, the transfer case 300 includes a driven shaft 340, which is rotatably disposed inside the transfer case 300. One end of the driven shaft 340 is connected to the end of the output shaft 210 away from the drive device 100, and the other end of the driven shaft 340 is connected to the transmission output end 310. For example, Figure 4 and Figure 5As shown, the driven shaft 340 is located in the axial direction of the output shaft 210, so that the transmission output end 310 on the driven shaft 340 is also located in the axial direction of the output shaft 210. In this part, the role of the driven shaft 340 is similar to that of an extension of the output shaft 210. The output shaft 210 transmits power to the driven shaft 340, and then the driven shaft 340 transmits power from the transmission output end 310 to the differential of the rear axle to provide power for the model car.

[0045] In some embodiments of the present invention, a coupling 400 is provided at the connection between the output shaft 210 and the driven shaft 340. Figure 4 and Figure 5 As shown, in this embodiment, the output shaft 210 and the driven shaft 340 have the same diameter. After the output shaft 210 and the driven shaft 340 are spliced, the diameter of the splicing position is the same as the diameter of the output shaft 210 and the driven shaft 340, and after splicing, the output shaft 210 can drive the driven shaft 340 to rotate. At the same time, the coupling 400 is sleeved between the output shaft 210 and the driven shaft 340, which can prevent the connection between the output shaft 210 and the driven shaft 340 from being detached, so that the output shaft 210 can continue to drive the driven shaft 340 to rotate.

[0046] Furthermore, a clearance hole is recessed in the rotating connecting column 330, and the clearance hole is connected to the interior of the gearbox 200, and the rotating connecting groove 220 is connected to the interior of the gearbox 300. The end of the driven shaft 340 close to the driving device 100 extends into the clearance hole, and the output shaft 210 passes through the rotating connecting groove 220 and extends into the clearance hole to be connected to the driven shaft 340.

[0047] In some embodiments of the present invention, the transfer case 300 further includes a first transfer gear 350, a clamping member 381, and a second transfer gear 360. The first transfer gear 350 is rotatably sleeved on the driven shaft 340. The clamping member 381 can be engaged with the driven shaft 340 along the axis of the driven shaft 340 so as to approach or move away from the first transfer gear 350. A second transfer shaft is passed through the second transfer gear 360. The side of the second transfer shaft close to the drive device 100 is connected to the transfer output end 320. The second transfer gear 360 is in transmission connection with the first transfer gear 350. When the clamping member 381 approaches and engages with the first transfer gear 350, the driven shaft 340 can drive the first transfer gear 350 to rotate through the clamping member 381, so that the first transfer gear 350 drives the second transfer shaft to rotate through the second transfer gear 360. For example, Figure 4 and Figure 5As shown, in this embodiment, a hexagonal structure is provided on the peripheral side surface of the middle section of the driven shaft 340, and a mounting hole is passed through the clamping member 381, wherein the shape of the mounting hole is a hexagonal structure and is adapted to the hexagonal structure on the peripheral side surface of the driven shaft 340. The clamping member 381 is sleeved and engaged on the driven shaft 340, and the driven shaft 340 can drive the clamping member 381 to rotate together. The first transfer gear 350 is sleeved on the driven shaft 340, but the driven shaft 340 cannot directly drive the first transfer gear 350 to rotate. When the transfer case 300 is working, when the clamping member 381 is located away from the first transfer gear 350, the output shaft 210 drives the driven shaft 340 to rotate. The driven shaft 340 rotates and transmits power to the transmission output end 310, and drives the clamping member 381 to rotate. When the clamping member 381 is located close to and engaged with the first transfer gear 350, the output shaft 210 drives the driven shaft 340 to rotate. The driven shaft 340 rotates to transmit power to the transmission output end 310. At the same time, the clamping member 381 rotates as the driven shaft 340 rotates, and drives the first transfer gear 350 to rotate, so that the first transfer gear 350 drives the second transfer gear 360 to rotate, and then transmits power to the transfer output end 320 through the second transfer shaft, so that the transfer case 300 can selectively transmit power to the transfer output end 320.

[0048] In some embodiments of the present invention, a third transfer gear 370 is further provided between the first transfer gear 350 and the second transfer gear 360. The third transfer gear 370 is engaged with the first transfer gear 350 and the second transfer gear 360 respectively. The first transfer gear 350 drives the second transfer gear 360 to rotate through the third transfer gear 370. For example, Figure 4 and Figure 5 As shown, the third transfer gear 370 is rotatably arranged in the transfer case 300, and the third transfer gear 370 is respectively engaged with the first transfer gear 350 and the second transfer gear 360. When the clamping member 381 approaches and engages with the first transfer gear 350, the first transfer gear 350 can drive the third transfer gear 370 to rotate, and at the same time, the third transfer gear 370 drives the second transfer gear 360 to rotate. Adding the third transfer gear 370 in the transfer case 300 can increase the power transmission distance of the first transfer gear 350, so that the first transfer gear 350 can transmit power to the transfer output end 320 of the second transfer shaft with the help of the third transfer gear 370.

[0049] In some embodiments of the present invention, a first clamping block 384 is provided on one side of the clamping member 381 close to the first transfer gear 350, and a second clamping block 351 is provided on the side of the first transfer gear 350. The first clamping block 384 and the second clamping block 351 are staggered and engaged with each other. Figure 4 and Figure 5As shown, in this embodiment, the first clamping blocks 384 are protruded on both sides of the clamping member 381, and four first clamping blocks 384 are protruded on each side. The four first clamping blocks 384 are circumferentially and equidistantly distributed on the side of the clamping member 381, and the clamping member 381 can only slide along the axial direction of the driven shaft 340 and cannot rotate relative to the driven shaft 340. Four second clamping blocks 351 are protruded on the side of the first transfer gear 350 close to the first transfer gear 350. The four second clamping blocks 351 The second clamping blocks 351 are distributed circumferentially and equidistantly on the side surface of the first transfer gear 350. The shape and size of the second clamping blocks 351 are the same as those of the first clamping blocks 384, but the four first clamping blocks 384 and the four second clamping blocks 351 are staggered with each other. When the clamping member 381 approaches the first transfer gear 350, the four first clamping blocks 384 and the four second clamping blocks 351 engage with each other, and there is no relative rotation between the first transfer gear 350 and the clamping member 381, so that the clamping member 381 can drive the first transfer gear 350 to rotate.

[0050] In some specific embodiments of the present invention, the transfer case 300 is further provided with a guide rod 382 and a transfer member 383. The guide rod 382 is slidably mounted in the transfer case 300. The transfer member 383 is mounted on the guide rod 382 and is relatively rotatably engaged with the side of the clamping member 381. The guide rod 382 can drive the clamping member 381 to move closer to or away from the first transfer gear 350 through the transfer member 383. For example, Figure 2 、 Figure 4 and Figure 5 As shown, in this embodiment, a connecting rod is connected between the transfer case 300 controller and the guide rod 382. The transfer case 300 controller controls the guide rod 382 to slide back and forth along the axial direction of the driven shaft 340 through the connecting rod. One side of the transfer member 383 is annular and is sleeved on the guide rod 382. The other side of the transfer member 383 is semi-annular, and an annular groove is recessed on the circumferential side surface of the clamping member 381. The side of the semi-annular structure on the transfer member 383 is engaged in the annular groove of the clamping member 381. At the same time, relative rotation can occur between the transfer member 383 and the clamping member 381. The transfer member 383 is mainly used to assist the guide rod 382 to drive the clamping member 381 close to or away from the first transfer gear 350, thereby realizing the conversion of the model car from two-wheel drive to four-wheel drive.

[0051] In some specific embodiments of the present invention, a drive device 100 is further included. The drive device 100 is provided with an output gear. A driven gear is provided between the output gear and the output shaft 210. The output gear drives the output shaft 210 to rotate via the driven gear. In this embodiment, the drive device 100 is a motor. The output gear is provided at the output end of the motor. The output shaft 210 is sleeved with a driven gear (not shown). The output gear and the driven gear are in transmission connection. The output gear on the motor can transmit the power from the motor to the output shaft 210 via the output gear, thereby driving the output shaft 210 to rotate and realize power output.

[0052] While the embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited to the embodiments described above. Various modifications may be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention.
