Description

Technical Field

[0001] The utility model relates to the technical field of motorcycles, in particular to a motorcycle anti-rollover bracket device. Background Art

[0002] A motorcycle is a two-wheeled motor vehicle consisting of an engine, frame, suspension system and other components. Before a motorcycle equipped with ABS is put on the road, the ABS needs to be tested to ensure that its performance meets the requirements and is stable. The braking test part of this test is highly dangerous, so an anti-rollover device needs to be installed.

[0003] Most of the existing anti-rollover devices cannot meet the requirements at the same time, whether in terms of adapting to different vehicles or for different test conditions. In addition, when the motorcycle is tilting on both sides, most of the existing anti-rollover devices find it difficult to support and limit the motorcycle body while assisting the motorcycle body in resetting, which affects the stable use of the device. Utility Model Content

[0004] In view of the deficiencies of the prior art, the utility model provides a motorcycle anti-rollover bracket device to solve the problems raised by the above background technology.

[0005] The utility model provides the following technical scheme: a motorcycle anti-rollover bracket device comprises a motorcycle body, a fixing plate is fixedly assembled on the side of the motorcycle body, a support frame is arranged on the side of the fixing plate, a universal wheel is rotatably connected to the bottom of the support frame, a limiting frame is fixedly assembled on the side of the fixing plate, a limiting block is rotatably connected to the inner wall of the limiting frame, and the side of the limiting block is fixedly assembled to the side of the support frame, a supporting rod is fixedly assembled on the side of the fixing plate, a connecting block 1 is rotatably connected to the side of the fixing plate, a sliding cylinder is fixedly assembled on the side of the connecting block 1, an inner wall of the sliding cylinder is slidably connected to an inner cylinder, a cylinder is fixedly assembled on the bottom of the inner cylinder, a round rod is slidably connected to the inner wall of the cylinder, a connecting block 2 is fixedly assembled on the bottom of the round rod, and the side of the connecting block 2 is rotatably connected to the side of the support frame.

[0006] As a preferred technical solution of the utility model, the inner wall of the limiting frame is slidably connected with a bolt group, and the outer edge of the bolt group is rotatably sleeved with the inner wall of the limiting block.

[0007] As a preferred technical solution of the utility model, the inner wall of the slide cylinder is fixedly sleeved with a slide rod, the outer edge of the slide rod is slidably sleeved with the inner wall of the inner cylinder, the outer edge of the inner cylinder near the bottom is fixedly equipped with an outer cylinder, and the inner wall of the outer cylinder is slidably sleeved with the outer edge of the slide cylinder.

[0008] As a preferred technical solution of the utility model, an air inlet groove is opened on the top of the inner cylinder, a tympanum is fixedly mounted on the inner wall of the inner cylinder, and the inner wall of the tympanum passes through the inner wall of the air inlet groove and is connected with the inner wall of the slide cylinder.

[0009] As a preferred technical solution of the utility model, a spring is fixedly connected to the top of the inner wall of the cylinder, and the bottom of the spring is fixedly connected to the top of the round rod.

[0010] As a preferred technical solution of the utility model, there are two limit frames, and the inner walls of the two limit frames are respectively rotatably connected to a limit block, and there are two support frames, and the two support frames are respectively arranged on both sides of the motorcycle body, and the connection mechanisms of the two support frames and the motorcycle body are completely consistent.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The motorcycle anti-rollover bracket device is installed on the side of the motorcycle body by using a fixing plate in conjunction with the motorcycle body, and the fixing plate is assisted by screws. It has a simple structure and is easy to install. Compared with other structures, it reduces the difficulty of operation for operators and saves costs. It can effectively save time in subsequent tests of various working conditions.

[0013] 2. The motorcycle anti-rollover support device floats when the motorcycle body tilts. When the angle reaches the limit point, it cannot be increased any further. During this process, if the vehicle loses control, the support rod provides auxiliary limit support to the support frame, thereby protecting the personnel.

[0014] 3. The motorcycle anti-rollover support device is used through the cooperation of the sliding rod and the inner tube. When the support frame rotates and tilts, the sliding rod moves toward the inner tube, so that the sliding rod drives the internal gas of the sliding tube to pass through the inner wall of the air intake groove to the inner wall of the eardrum, and then the outer edge of the eardrum is used to assist in limiting the outer edge of the sliding rod, thereby assisting in shock absorption of the support frame.

[0015] 4. The motorcycle anti-rollover support device uses a cylinder and a round rod in combination. When the support frame rotates and tilts, the round rod slides in the inner wall of the cylinder and is pushed back to its original position with the help of a spring, thereby reducing the force required for the motorcycle body to be reset after tilting, facilitating stable driving while avoiding rollover.
