Description

[0002] Conventional remote control car models are divided into racing, drifting, climbing, and off-road types. When a remote control car model turns, it usually realizes the turn by deflecting the front wheels by a certain angle. Due to the limitation of the front wheel deflection angle, the turning radius is usually large. Especially in the case of no differential, the speed mismatch between the inner and outer wheels will cause the remote control car model to be unable to achieve an ideal turning radius, such as being unable to perform a U-turn in place, thus affecting flexibility and maneuverability. When the transmission performance is poor, the speed mismatch between the inner and outer wheels will also cause tail sliding or pushing phenomena. Summary of the Invention

[0034] Next, embodiments of the present invention will be described in conjunction with the accompanying drawings.
[0035] The first embodiment of the present application discloses a transmission structure for the center turning of a remote control car model. As Figure 1 and Figure 2 shown, it includes a first half shaft gear 3, a second half shaft gear 4 and a clutch assembly. The remote control car model includes a first wheel 6 and a second wheel 7.
[0036] The first half shaft gear 3 is connected to the first wheel 6 to achieve co-rotation. For example, a first rotating shaft 31 is provided between the first half shaft gear 3 and the first wheel 6. One end of the first rotating shaft 31 is fixedly connected to the first half shaft gear 3, and the other end is connected to the first wheel 6. In order to achieve the left and right deflection of the first wheel 6, a cup can be provided between the other end of the first rotating shaft 31 and the first wheel 6.
[0037] The first half shaft gear 3 and the second half shaft gear 4 are set to rotate in opposite directions. For example, a driving gear 5 is respectively meshed with the first half shaft gear 3 and the second half shaft gear 4, and the driving mechanism is used to achieve the reverse rotation of the two half shaft gears. The connection manner between the driving mechanism and the driving gear 5 is a prior art, and the embodiments of the present invention do not limit it here. There are also other implementation manners for setting the first half shaft gear 3 and the second half shaft gear 4 to rotate in opposite directions, and the embodiments of the present invention do not limit it here.
[0038] The clutch assembly includes a conversion clutch 1 and a clutch shaft 11. The conversion clutch 1 is movably sleeved on the clutch shaft 11, and the two can rotate synchronously. Specifically, the outer surface of the clutch shaft 11 in contact with the conversion clutch 1 can be set to be non-circular, and the inner surface of the conversion clutch 1 is matched with the outer surface of the clutch shaft 11. In the specific implementation process, the outer surface of the clutch shaft 11 in contact with the conversion clutch 1 can be polygonal, concave-convex shaped or other non-circular shapes, such as Figure 3 and Figure 5 the hexagon shown in Figure 4 and Figure 6 the gear shape shown in. The inner surface of the conversion clutch 1 is configured according to the cross-section of the clutch shaft 11 to ensure that the conversion clutch 1 and the clutch shaft 11 can rotate synchronously.
[0039] The clutch shaft 11 is rotatably connected to the first half shaft gear 3 and the second half shaft gear 4 respectively, and the clutch shaft 11 is connected to the second wheel 7 to achieve co-rotation; for example, the transmission structure further includes a third rotating shaft 2. One end of the third rotating shaft 2 is fixedly connected to the clutch shaft 11, and the other end is connected to the second wheel 7. In order to realize the left and right deflection of the second wheel 7, a cup can be provided between the other end of the third rotating shaft 2 and the second wheel 7. There are also other implementation manners for the connection manner between the clutch shaft 11 and the second wheel 7, which are not limited in the embodiments of the present invention.
[0040] The transmission structure further includes a second rotating shaft 41, and the second rotating shaft 41 is fixedly connected to the second half shaft gear 4. The second rotating shaft 41 is rotatably sleeved on the third rotating shaft 2.
[0041] The conversion clutch 1 includes a first position and a second position. In the first position, the conversion clutch 1 is fixedly connected to the first half shaft gear 3, so that the first half shaft gear 3 drives the first wheel 6 and the second wheel 7 to rotate in the same direction; in the second position, the conversion clutch 1 is connected to the second half shaft gear 4, so that the second half shaft gear 4 drives the second wheel 7 to rotate, and the second wheel 7 rotates in the opposite direction to the first wheel 6.
[0042] In an optional implementation manner, the connection part between the conversion clutch 1 and the first half shaft gear 3 or the second half shaft gear 4 is non-circular, and grooves 32, 42 are provided on the first half shaft gear 3 and the second half shaft gear 4, and the grooves 32, 42 are matched with the conversion clutch 1. Specifically, the connection part between the conversion clutch 1 and the first half shaft gear 3 or the second half shaft gear 4 can be polygonal or concave-convex shaped, and the grooves 32, 42 are configured for cooperation, such as Figure 1 , Figure 2 , Figure 7 and Figure 8 shown in. Figure 7 and Figure 8The sectional view shows the conversion clutch 1 in the first position when converting from the second round to the first round direction. The sectional view of the conversion clutch 1 in the second position when converting from the first round to the second round direction is similar. The shape of the connection between the conversion clutch 1 and the first half-shaft gear 3 or the second half-shaft gear 4 is not limited to the hexagon or gear shape shown in the figure. The conversion clutch 1 can be wholly or partly arranged in the grooves 32, 42. When in the first position, the conversion clutch 1 cooperates with the groove 32, and the first half-shaft gear 3 drives the conversion clutch 1 to rotate, thereby driving the clutch shaft 11 to rotate. After the clutch shaft 11 rotates, it drives the second round 7 to rotate. The first round 6 and the second round 7 rotate in the same direction. At this time, the second half-shaft gear 4 idles, and the actual remote control car model moves forward or backward. When in the second position, the conversion clutch 1 cooperates with the groove 42, and the second half-shaft gear 4 drives the conversion clutch 1 to rotate, thereby driving the clutch shaft 11 to rotate. After the clutch shaft 11 rotates, it drives the second round 7 to rotate. The first round 6 and the second round 7 rotate in the opposite direction to achieve a center turn.
[0043] In another alternative implementation, the outer surface of the conversion clutch 1 is provided with protrusions and / or grooves, and the first half-shaft gear 3 and the second half-shaft gear 4 are provided with matching grooves and / or protrusions.
[0044] Optionally, protrusions can be provided on both outer surfaces in the axial direction of the conversion clutch 1, and matching grooves are provided on the first half-shaft gear 3 and the second half-shaft gear 4. When in the first position, the protrusions on the conversion clutch 1 cooperate with the groove 32 on the first half-shaft gear 3, and the first half-shaft gear 3 drives the conversion clutch 1 to rotate, thereby driving the clutch shaft 11 to rotate. After the clutch shaft 11 rotates, it drives the second round 7 to rotate. The first round 6 and the second round 7 rotate in the same direction. At this time, the second half-shaft gear 4 idles, and the actual RC car model moves forward or backward. When in the second position, the protrusions on the conversion clutch 1 cooperate with the groove 42 on the second half-shaft gear 4, and the second half-shaft gear 4 drives the conversion clutch 1 to rotate, thereby driving the clutch shaft 11 to rotate. After the clutch shaft 11 rotates, it drives the second round 7 to rotate. The first round 6 and the second round 7 rotate in the opposite direction to achieve a center turn. For example, Figure 9 For a conversion clutch 1, a plurality of protrusions 12 are provided on both outer surfaces on its two sides, Figure 10 It is a cross-sectional view of the first half-shaft gear 3, on which a matching first groove 33 is provided. The setting on the second half-shaft gear 4 is similar.
[0045] Optionally, grooves can be provided on both outer surfaces in the axial direction of the conversion clutch 1, and matching protrusions are provided on the first half-shaft gear 3 and the second half-shaft gear 4.
[0046] Optionally, protrusions can be provided on one of the two outer surfaces in the axial direction of the conversion clutch 1, and matching grooves are provided on the adjacent half-shaft gear; grooves are provided on the other outer surface, and matching protrusions are provided on the adjacent half-shaft gear.
[0047] In the specific implementation process, it can be flexibly set according to actual needs.
[0048] The clutch assembly further includes a conversion clutch driving mechanism. The conversion clutch 1 further includes an intermediate position, which is located between the first position and the second position. In the intermediate position, the conversion clutch 1 is in a non-connected state with the first half shaft gear 3 and the second half shaft gear 4. The conversion clutch driving mechanism is used to drive the conversion clutch 1 to switch between the first position, the intermediate position and the second position.
[0049] In some embodiments, as Figure 12 shown, in order to move the conversion clutch 1 to the first position or the second position, the conversion clutch driving mechanism may include a fork gear 13, a fork 14 and a servo. The fork gear 13 is connected to the fork 14, the servo (not shown in the figure) is connected to the fork gear 13, and the fork 14 cooperates with the conversion clutch 1. The servo rotates the fork 14 through the fork gear 13. When the fork 14 rotates, it pushes the conversion clutch 1 to move left and right. And when the conversion clutch 1 is in the first position or the second position, the fork 14 is in a stationary state. In order to achieve the cooperation between the fork 14 and the conversion clutch 1, a notch may be opened on the surface of the conversion clutch 1, or a connecting portion may be provided between the connection of the conversion clutch 1 and the first half shaft gear 3 and the connection of the conversion clutch 1 and the second half shaft gear 4 to form a notch, and a part of the fork 14 is arranged in the notch to ensure that the fork 14 can push the conversion clutch 1 to move left and right when rotating, and when the conversion clutch is in the first position or the second position, the fork 14 is in a stationary state. Of course, there are many cooperation methods between the fork 14 and the conversion clutch 1, which belong to the prior art, and the embodiments of the present invention do not limit them here.
[0050] In other embodiments, the conversion clutch driving mechanism may include a brake cable and a servo, and the transmission control method of the brake cable is used to realize the left and right displacement of the conversion clutch 1. The servo pulls the brake cable to control the left and right movement of the fork to drive the conversion clutch 1 to switch between the first position and the second position.
[0051] In addition to the above ways to realize the conversion clutch 1 in the first position or the second position, there are also various implementation ways, and the embodiments of the present invention do not limit them here.
[0052] The second embodiment of the present application discloses a remote control car model, including a front axle and a rear axle, and both the front axle and the rear axle include the transmission structure for the remote control car model to turn around the center.
[0053] The third embodiment of the present application discloses a control method for the center turn of a remote control car model, which is applied to the remote control car model, and includes: synchronously controlling the conversion clutch 1 of the front axle and the rear axle to move to the second position in the same way, so that the conversion clutch 1 is connected to the second half axle gear 4, and the second half axle gear 4 drives the second wheel 7 to rotate. At this time, the first half axle gear 3 drives the first wheel 6 to rotate in the reverse direction, so as to realize the center turn of the remote control car model.
[0054] In the specific implementation process, the control module of the remote control car model can send the same signal to the servos of the front axle and the rear axle at the same time, so that the servos of the front axle and the rear axle simultaneously control the corresponding fork gears 13 to rotate the fork 14. The fork 14 rotates and pushes the corresponding conversion clutch 1 to move to the second position.

[0058] The first half axle gear 3 is connected to the first wheel 6 to achieve the same direction of rotation. As Figure 1 shown, a first rotating shaft 31 is provided between the first half axle gear 3 and the first wheel 6. One end of the first rotating shaft 31 is fixedly connected to the first half axle gear 3, and the other end is connected to the first wheel 6.
[0059] The first half axle gear 3 and the second half axle gear 4 are set to rotate in the reverse direction; as Figure 1 shown, the transmission structure is provided with a power gear 5, and the power gear 5 is meshed and connected to the first half axle gear 3 and the second half axle gear 4 respectively, and the reverse rotation of the two half axle gears is realized through a power mechanism. The connection method between the power mechanism and the power gear 5 is the prior art, and this embodiment does not limit it here.
[0060] The clutch assembly includes a conversion clutch 1 and a clutch shaft 11. The conversion clutch 1 is movably sleeved on the clutch shaft 11, and the two can rotate synchronously; as Figure 1 and Figure 4 shown, the cross section of the clutch shaft 11 is gear-shaped, and the inner surface of the conversion clutch 1 is set according to the cross section of the clutch shaft 11 to ensure that the conversion clutch 1 and the clutch shaft 11 can rotate synchronously.
[0061] The clutch shaft 11 is rotatably connected to the first half shaft gear 3 and the second half shaft gear 4 respectively. The clutch shaft 11 is connected to the second wheel 7 to achieve co-rotation; for example, the transmission structure further includes a third rotating shaft 2. One end of the third rotating shaft 2 is fixedly connected to the clutch shaft 11, and the other end is connected to the second wheel 7, as Figure 11 shown.
[0062] The transmission structure further includes a second rotating shaft 41. The second rotating shaft 41 is fixedly connected to the second half shaft gear 4. The second rotating shaft 41 is rotatably sleeved on the third rotating shaft 2.
[0063] Bearings can be provided at one end of the first rotating shaft 31 close to the first half shaft gear 3, and bearings can be provided at one end of the second rotating shaft 41 close to the second half shaft gear 4. The clutch shaft 11 is arranged in the bearings to achieve rotatable connection.
[0064] The conversion clutch 1 includes a first position and a second position. In the first position, the conversion clutch 1 is fixedly connected to the first half shaft gear 3, so that the first half shaft gear 3 drives the first wheel 6 and the second wheel 7 to rotate in the same direction; in the second position, the conversion clutch 1 is connected to the second half shaft gear 4, so that the second half shaft gear 4 drives the second wheel 7 to rotate, and the second wheel 7 rotates in the opposite direction to the first wheel 6.
[0065] As Figure 1 , Figure 2 and Figure 7 shown, the cross section of the conversion clutch 1 is gear-shaped. Gear-shaped grooves 32 and 42 are provided on the first half shaft gear 3 and the second half shaft gear 4. The grooves 32 and 42 cooperate with the conversion clutch 1. The conversion clutch 1 can be wholly or partly arranged in the grooves 32 and 42. So that in the first position, the conversion clutch 1 cooperates with the groove 32. The first half shaft gear 3 drives the conversion clutch 1 to rotate, thereby driving the clutch shaft 11 to rotate. After the clutch shaft 11 rotates, it drives the second wheel 7 to rotate. The first wheel 6 and the second wheel 7 rotate in the same direction. At this time, the second half shaft gear 4 idles, and the actual remote control car model moves forward or backward. In the second position, the conversion clutch 1 cooperates with the groove 42. The second half shaft gear 4 drives the conversion clutch 1 to rotate, thereby driving the clutch shaft 11 to rotate. After the clutch shaft 11 rotates, it drives the second wheel 7 to rotate. The first wheel 6 and the second wheel 7 rotate in the opposite direction, realizing the center turning of the remote control car model.
[0066] When the remote control car model needs to turn at the center, the conversion clutches 1 of the front axle and the rear axle are synchronously controlled to move to the second position in the same way, so that the conversion clutch 1 is connected to the second half shaft gear 4. The second half shaft gear 4 drives the second wheel 7 to rotate. At this time, the first half shaft gear 3 drives the first wheel 6 to rotate in the opposite direction, that is, the right front and rear wheels of the car rotate forward, and the left front and rear wheels rotate backward, realizing the center turning of the remote control car model with the center of the four wheels as the center.
[0067] The fourth embodiment of this application discloses an auxiliary steering control method for a remote control car model, which is applied to the remote control car model described above and includes: controlling the conversion clutch 1 of the front axle and the rear axle to move to the first position so that the first wheel and the second wheel rotate in the same direction; controlling the conversion clutch 1 of the rear axle to periodically move to the second position so that the first wheel and the second wheel of the rear axle rotate in the opposite direction, thereby realizing the auxiliary steering control of the remote control car model. In the specific implementation process, the steering is realized by a dedicated steering servo. Here, the periodic reverse rotation of the rear axle is to make the turning radius of the steering action without a differential smaller, or to avoid overturning when the whole vehicle turns during fast driving.
[0068] In the specific implementation process, the control module of the remote control car model sends a first signal to the servos of the front axle and the rear axle, so that the servos of the front axle and the rear axle control the corresponding fork gears 13 to rotate the fork 14. When the fork 14 rotates, it pushes the corresponding conversion clutch 1 to move to the first position. When steering is required, the control module periodically sends a second signal to the servo of the rear axle, so that the servo of the rear axle controls the corresponding fork gear 13 to rotate the fork 14. When the fork 14 rotates, it pushes the corresponding conversion clutch 1 to move to the second position, so that the first wheel and the second wheel of the rear axle rotate in the opposite direction, thereby realizing the steering of the remote control car model.
[0069] In the specific implementation, this application provides a computer storage medium and a corresponding data processing unit. Among them, the computer storage medium can store a computer program.
