Description

Technical Field

[0001] This utility model belongs to the field of automobile model technology, and in particular relates to an adjustable posture automobile model chassis. Background Technology

[0002] The purpose of using a car development model is to meet various possibilities, so changes in posture become a requirement, which is achieved by changing the position of the four wheels relative to the car body.

[0003] The current method uses fixed guide grooves to allow the wheel axle with the tire to slide forward, backward, left, right, up, and down. The technical drawback is that the operation is complicated. It requires lifting the car to remove the tire, adjusting the screw position, installing the tire, and measuring the posture, and then repeating the cycle until the desired posture is achieved. Therefore, an adjustable posture car model chassis is proposed to solve the problem of complicated operation of adjusting the car chassis. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable posture car model chassis to solve existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an adjustable posture car model chassis, comprising a base plate. A mounting groove is formed on the upper surface of the base plate. Symmetrical sliding grooves are formed on opposite surfaces of the base plate, and a sliding rod is disposed within each sliding groove. A first servo motor is disposed on the inner wall of the left side of the mounting groove, and a worm gear is rotatably connected to the inner wall of the right side of the mounting groove. Multiple sets of fixing plates are symmetrically arranged on the bottom surface of the base plate, and bidirectional screws are rotatably connected within these fixing plates. A worm wheel is fitted onto the center of the circumferential side of each bidirectional screw, and threaded collars are threadedly connected to the circumferential sides of both ends of the bidirectional screw. Connecting plates are disposed on the circumferential sides of the threaded collars. Both ends of the connecting plate are equipped with lifting devices. One side of each lifting device has an adjustment groove, and a threaded rod is rotatably connected within the adjustment groove. An adjustment block is inserted through the periphery of the threaded rod. A second servo motor is mounted on the upper surface of the lifting device. A mounting column is rotatably connected to one side of each adjustment block, and a moving wheel is rotatably connected to one end of the mounting column. A guide block is slidably connected to the periphery of the sliding rod. Several energy-absorbing devices are provided on the front and rear sides of the base plate. Several sliders are symmetrically arranged on the upper surface of the base plate. Insert rods are slidably connected within each slider, and a buffer block is provided at one end of each insert rod.

[0007] Furthermore, the energy-absorbing device includes a sleeve, a hollow tube slidably connected inside the sleeve, a spring provided on one side of the inner wall of the sleeve, the free end of the spring being fixedly connected to one side of the inner wall of the hollow tube, one side of the sleeve being fixedly connected to the front and rear sides of the base plate respectively, and one side of the hollow tube being fixedly connected to one side of the buffer block.

[0008] Furthermore, a battery box is provided on the upper surface of the base plate, the output end of the first servo motor is fixedly connected to the left end of the worm gear, the worm gear meshes with the worm wheel, one side of the guide block is fixedly connected to one side of the lifting device, the threaded rod is threadedly engaged with the adjusting block, and the battery box is electrically connected to the first servo motor and the second servo motor.

[0009] This utility model has the following beneficial effects:

[0010] This invention utilizes a first servo motor to drive a worm gear to rotate. The worm gear meshes with a worm wheel, which in turn drives a bidirectional screw to rotate. Simultaneously, the rotation of the bidirectional screw causes the threaded collars at both ends to reciprocate. As the threaded collars reciprocate, they adjust the lifting devices and moving wheels at both ends via a connecting plate. At the same time, a second servo motor is started, driving a threaded rod to rotate. The rotation of the threaded rod causes the adjusting block with threaded engagement on its circumferential side, along with the moving wheel, to move up and down within the adjusting groove, thus completing the attitude adjustment.

[0011] Meanwhile, the buffer blocks and energy absorption devices set on the front and rear sides of the base plate can prevent the model from being damaged by collision. When a collision occurs, the buffer blocks, together with the hollow tube compression spring, absorb the impact generated during the collision.

[0012] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
