AI Technical Summary
The front and rear wheel suspensions in the existing vehicle model back-up mechanism are generally connected together, resulting in the wheels being able to move up and down to a smaller extent, and cannot adapt to vehicles with large up and down movements such as off-road vehicles, which reduces the playful feel and playability of the vehicle model.
A mechanism for vehicle model wheel force feedback and automatic body correction is designed. By setting a rectangular groove and limit frame on the vehicle model chassis, and installing micro-force springs and flatbeds on the front and rear lateral suspensions, the suspension can be displaced up and down as a whole and swing left and right, achieving a large up and down displacement.
During the implementation of the vehicle model, the left and right swings of the front wheels when encountering obstacles and the overall upper and lower displacement and left and right swing of the rear transverse suspension are realized. Combined with the micro-force spring and the flat plate, the rear transverse suspension can be rebounded and returned to the chassis and body of the vehicle model to move on the ground, improving the playful feel and playability of the vehicle model.

[0001] The utility model relates to the technical field of mechanisms for wheel force feedback and body automatic alignment of vehicle models, and particularly to a mechanism for wheel force feedback and body automatic alignment of vehicle models. Background Art
[0002] The steering return mechanism is an important part of the vehicle steering system. Its main function is to automatically generate a reverse torque after the wheels are steered, so that the wheels can automatically return to the straight position.
[0003] In the existing vehicle model return mechanisms, the front and rear wheel suspensions are generally connected together. When playing, the wheels can only move up and down with a small amplitude, resulting in being not suitable for vehicles such as off-road vehicles with a large amplitude of up and down movement of the wheels, and reducing the playing feel and playability of the vehicle model. Summary of the Utility Model
[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to provide a mechanism for wheel force feedback and body automatic alignment of a vehicle model.

At the top of one end of the vehicle model chassis, a second longitudinal axis limiting frame is arranged. Both ends of the front transverse suspension are rotatably connected with front wheels. The front transverse suspension is inserted into the rectangular groove at one end close to the first longitudinal axis limiting frame. A longitudinal rotating shaft is arranged on the inner wall of the top of the front transverse suspension. The rear transverse suspension is inserted into the rectangular groove at one end close to the second longitudinal limiting frame. Both ends of the rear transverse suspension are rotatably connected with rear wheels. A leveling plate is arranged on the inner wall of the top of the rear transverse suspension. Micropower springs are symmetrically and fixedly connected to the tops of the front transverse suspension and the rear transverse suspension.

In conjunction with the micro-force spring and the leveling plate, the rear transverse suspension can be rebounded and the chassis and body of the vehicle model can be straightened so that it can run on the ground, thereby realizing a larger up and down displacement. It is suitable for vehicles such as off-road vehicles with a large up and down movement of wheels, and improves the playability and playability of the vehicle model.
[0007] Preferably, the longitudinal cross-section of the longitudinal rotation axis is circular, and the longitudinal rotation axis is clamped in the first longitudinal limit frame.
[0008] The effect achieved by the above components is: by setting the longitudinal rotation axis in a round rod shape, the front transverse suspension can be fixed in the rectangular groove on the chassis of the vehicle model, and a fulcrum for the longitudinal left and right swing of the front transverse suspension is provided. At the same time, it is clamped in the first longitudinal axis limit frame to prevent the longitudinal rotation axis from falling off during rotation, and provide space for it to move up and down.
[0009] Preferably, the longitudinal section of the leveling plate is rectangular, and the leveling plate is clamped in the second longitudinal limiting frame.
[0010] The effect achieved by the above components is: by setting the leveling plate into a rectangular shape, the square structure changes the center rotation point from the center to the two side structures when the rear transverse suspension swings left and right, and relies on the larger contact surface to make it self-centering and stabilize the body posture. At the same time, it is clamped in the second longitudinal axis limit frame to prevent the leveling plate from falling off during rotation, providing it with space for up and down movement.
[0011] Preferably, one side of the front transverse suspension and the rear transverse suspension and the inner walls of the two rectangular grooves are symmetrically fixedly connected with limit blocks, and the outer surface of the limit blocks is sleeve-connected with the inner wall of the micro-force spring.
[0012] The effect achieved by the above components is: by setting the limit blocks, the inner walls at both ends of the micro-force spring can be supported and reinforced, so that it is not easy to deform and damage after bending within a certain range, thereby improving the service life of the micro-force spring.
[0013] Preferably, the inner walls of the first longitudinal axis limiting frame and the second longitudinal axis limiting frame are respectively communicated with the inner walls of the two rectangular grooves.
[0014] The effects achieved by the above components are as follows: By communicating the inner walls of the first longitudinal axis limiting frame and the second longitudinal axis limiting frame with the inner walls of the two rectangular grooves respectively, it is convenient to install the longitudinal rotating shaft and the leveling block, and it is convenient to limit the front transverse suspension and the rear transverse suspension and make them deflect in the rectangular grooves.
[0015] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0023] Reference Figures 1-4 As shown, this embodiment discloses that the longitudinal cross section of the longitudinal rotation axis 7 is circular, and the longitudinal rotation axis 7 is clamped in the first longitudinal limit frame. By setting the longitudinal rotation axis 7 in a round rod shape, the front transverse suspension 5 can be fixed in the rectangular groove 2 on the vehicle model chassis 1, and a fulcrum for the front transverse suspension 5 to swing left and right longitudinally is provided. At the same time, clamping it in the first longitudinal axis limit frame 3 can prevent the longitudinal rotation axis 7 from falling off during rotation, and provide space for it to move up and down.

When one of the front wheels 6 on one side encounters an obstacle during the pushing process, the front transverse suspension 5 swings left and right along the longitudinal rotating shaft 7 and is pushed back by the corresponding micro-force spring 11 after crossing the obstacle; the rear transverse suspension 8 also arranges micro-force springs 11 on both sides, and a leveling plate 9 is arranged at the center of the rear transverse suspension 8 and is clamped and limited in the second longitudinal axis limiting frame 4, so that it can realize the functions of the up and down overall displacement and left and right swing of the rear transverse suspension 8. Cooperating with the micro-force springs 11 and the leveling plate 9, the rear transverse suspension 8 can be bounced back and the chassis 1 and the body of the vehicle model can be aligned so that it travels on the ground, thereby realizing a large range of up and down displacement, which is suitable for vehicles such as off-road vehicles with a large up and down movement range of the wheels, and improving the playing feel and playability of the vehicle model.
