Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of toy cars, in particular to an electrically disconnectable anti-roll bar structure applied to a toy car. Background Art
[0002] Model car toys are already well-known. Off-road and rock climbing vehicles, in particular, are popular with people of all ages due to their numerous advantages, including high entertainment value, attractive appearance, and off-road capabilities. To enhance on-road stability, these vehicles are often equipped with anti-roll bars. However, to improve off-road maneuverability, the anti-roll bars must be removed, a relatively cumbersome process.
[0003] To facilitate disassembly, the utility model patent, publication number CN2751855Y, entitled "Improved Anti-roll Bar Fixing Structure for Remote Control Vehicles," discloses an improved anti-roll bar fixing structure for remote control vehicles, allowing for quick disassembly of the connecting parts. The invention features an angled coupling seat located near the middle of each lower arm of the remote control vehicle. A screw hole is located vertically in front of each coupling seat for a connecting part, the other end of which is connected to the anti-roll bar. To remove the anti-roll bar, a disassembly tool can be used to directly loosen the screws in the front screw hole of the outer angled coupling seat, achieving quick disassembly and assembly. However, disassembly and assembly still requires manual operation of the disassembly tool, which is cumbersome, time-consuming, and labor-intensive. Utility Model Content
[0004] In view of the above-mentioned shortcomings, the purpose of the present invention is to provide a remote control car anti-roll bar quick clutch mechanism with reasonable structural design, simple and convenient operation.
[0005] In order to achieve the above-mentioned purpose, the technical solution provided by the present utility model is:
[0006] A remote-controlled car anti-roll bar quick clutch mechanism comprises an anti-roll bar body, a steering gear, a drive arm, a linkage fork, a clutch housing and a pulling tooth. The anti-roll bar body comprises a rod body I and a rod body II. One end of the rod body I extends into the clutch housing and is provided with a transmission shaft end. The pulling tooth sleeve is provided on the transmission shaft end and can move axially while rotating with the rod body I. One end of the rod body II extends into the clutch housing and is provided with a shaft head tooth adapted to the pulling tooth. One end of the linkage fork extends into the clutch housing and is connected to the pulling tooth, and the other end is connected to the driving arm. The steering gear cooperates with the driving arm and the linkage fork to drive the pulling tooth to move axially and engage or disengage with the shaft head tooth.
[0007] As a preferred solution of the present invention, the clutch housing includes a main housing and a cover housing I and a cover housing II symmetrically arranged at both ends of the main housing, which has a simple structure and is easy to assemble.
[0008] As a preferred embodiment of the present invention, bearing I is mounted within cover shell I, compatible with rod body I. Bearing II is mounted within cover shell II, compatible with rod body II. This reduces friction and wear between rod bodies I and II during rotation, improving transmission efficiency and service life while ensuring smooth operation.
[0009] As a preferred solution of the present invention, the cross-sectional profile of the transmission shaft end is polygonal, such as a quadrilateral, a hexagon, etc., to ensure that the pulling tooth can rotate with the rod body I while also being able to move axially.
[0010] As a preferred solution of the present invention, the pulling tooth is provided with an axial hole that is compatible with the cross-sectional outline of the transmission shaft end, and the outer wall of the pulling tooth is provided with a pulling groove, which has a good matching effect with the linkage fork.
[0011] As a preferred solution of the present invention, one end of the linkage fork is provided with an arc-shaped claw adapted to the pulling groove, and the side wall of the arc-shaped claw is provided with a convex point, which can reduce friction and improve the smoothness of the pulling action.
[0012] As a preferred solution of the present invention, the end of the transmission shaft is provided with a concentric shaft, and the center of the shaft head teeth is provided with a concentric hole adapted to the concentric shaft, ensuring that rod body I and rod body II are on the same axis, so that the pulling teeth and the shaft head teeth can be accurately connected and disconnected.
[0013] As a preferred solution of the present invention, one end of the driving arm is fixed to the output shaft of the servo, and the other end is provided with a U-shaped groove, and the other end of the linkage fork is located in the U-shaped groove, which has a good matching effect.
[0014] The beneficial effects of the present invention are as follows: the present invention has a rational structural design, cleverly dividing the anti-roll bar into two sections, forming rod body I and rod body II. When the anti-roll bar function is not required, the steering gear, through the cooperation of the drive arm and the linkage fork, drives the pull-out tooth axially to separate from the shaft head tooth, thereby disconnecting rod body I and rod body II, and eliminating the anti-roll bar function. When the anti-roll bar function is required, the steering gear, through the cooperation of the drive arm and the linkage fork, drives the pull-out tooth axially to engage with the shaft head tooth, thereby connecting rod body I and rod body II to mutually restrain each other and obtain the anti-roll bar function. During operation, the anti-roll bar function can be quickly turned on and off by simply controlling the forward and reverse rotation of the steering gear, thereby meeting the driving requirements of the toy car on different road surfaces and different working conditions. The operation is simple and convenient, saving time and effort.
[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] For example, see Figures 1 to 3 The present embodiment provides a remote control car anti-roll bar quick clutch mechanism, which includes an anti-roll bar body, a steering gear 1, a driving arm 2, a linkage fork 3, a clutch housing 4 and a pulling tooth 5.
[0021] The anti-roll bar is split at the center into bar I6 and bar II7. The clutch housing 4 comprises a main housing 41, a cover housing I42, and a cover housing II43. Cover housings I42 and II43 are symmetrically fixed to the ends of the main housing 41 with screws. Two bearings I44 are located within cover housing I42, matching bar I6. Two bearings II45 are located within cover housing II43, matching bar II7.
[0022] One end of the rod body I6 extends into the clutch housing 4 and is provided with a transmission shaft end 61. The rod body I6 is mounted on the cover housing I42 via a bearing I44. The transmission shaft end 61 has a polygonal cross-sectional profile, such as a quadrilateral or hexagonal shape. This ensures that the puller tooth 5 can rotate with the rod body I6 while also moving axially. The puller tooth 5 is mounted on the transmission shaft end 61 and can rotate with the rod body I6 while also moving axially.
[0023] One end of the rod body II7 extends into the clutch housing 4 and is provided with a shaft head tooth 71 that is compatible with the pulling tooth 5. The rod body II7 is set on the cover housing II43 through the bearing II45. The shaft head tooth 71 is in the shape of a crown tooth, and the tooth shape on the pulling tooth 5 is also in the shape of a crown tooth, so as to realize the meshing connection between the pulling tooth 5 and the shaft head tooth 71. Preferably, a concentric shaft 62 is provided at the end of the transmission shaft end 61, and a concentric hole 72 that is compatible with the concentric shaft 62 is provided at the center position of the shaft head tooth 71. The concentric shaft 62 is inserted into the concentric hole 72 and can rotate freely, which can ensure that the rod body I6 and the rod body II7 are always on the same axis, so that the pulling tooth 5 and the shaft head tooth 71 can be accurately connected and disconnected.
[0024] One end of the linkage fork 3 extends into the clutch housing 4 and connects to the pull tooth 5. Specifically, the main housing 41 has an opening through which the linkage fork 3 extends. The pull tooth 5 is provided with an axial hole 51 that matches the cross-sectional profile of the transmission shaft end 61, and a pull groove 52 is formed on the outer wall of the pull tooth 5. One end of the linkage fork 3 extends through the opening and is equipped with a curved claw 31 that fits into the pull groove 52. The curved claw 31 fits snugly into the pull groove 52, driving the pull tooth 5 axially. Preferably, a protrusion 32 is provided on the side wall of the curved claw 31 to reduce friction and enhance the smoothness of the pull action.
[0025] One end of the driving arm 2 is fixed to the output shaft of the servo 1, and the other end is provided with a U-shaped groove. The other end of the linkage fork 3 is located in the U-shaped groove, so that the servo 1 can drive the pulling tooth 5 to axially move and engage or disengage with the shaft head tooth 71 through the cooperation of the driving arm 2 and the linkage fork 3.
[0026] See also Figure 4 The utility model is installed on a car model toy, and the steering engine 1 is connected to the circuit board of the car model toy. The steering engine 1 can be controlled to rotate forward or reverse by the remote control of the car model toy.
[0027] When the anti-roll bar function is not required, the servo 1, through the drive arm 2 and linkage fork 3, drives the puller tooth 5 axially to disengage from the shaft head tooth 71, disconnecting rod I 6 from rod II 7 and disabling the anti-roll bar function. When the anti-roll bar function is required, the servo 1, through the drive arm 2 and linkage fork 3, drives the puller tooth 5 axially to engage with the shaft head tooth 71, connecting rod I 6 and rod II 7 to restrain each other and provide the anti-roll bar function. The anti-roll bar function can be quickly activated or deactivated by simply controlling the forward or reverse rotation of the servo 1, meeting the driving needs of the toy car on various road surfaces and operating conditions. Operation is simple and convenient.
