Embodiment Construction

[0017] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0018] refer to Figure 1~Figure 2 As shown, a trailer booster includes a drive mechanism for driving the trailer to move, the drive mechanism includes a friction roller 3, and a DC motor 12 for driving the friction roller to rotate, the DC motor and A gearbox 21 is also arranged between the friction rollers. The rotation of the friction rollers drives the wheels of the trailer to rotate, thereby driving the trailer to move. The driving mechanism is fixed on a mobile bracket 2, and the mobile bracket is movably arranged on On the fixed bracket 1, the fixed bracket is also provided with a displacement mechanism, which adjusts the relative position of the movable bracket and the fixed bracket, and the displacement mechanism includes a manual displacement device and an electric displacement device. The manual displacement device can adjust ...

Abstract

The invention relates to a trailer power assisting device that includes a driving mechanism; the driving mechanism comprises friction rollers, and a direct current motor; a gearbox is also arranged between the direct current motor and the friction roller; the friction rollers rotate to drive wheels of the trailer to rotate, thus driving the trailer to move; the driving mechanism is fixedly arranged on a movable support, the movable support is movably arranged on a fixed support, the fixed support is further provided with a position changing mechanism which is used for adjusting the relative positions of the movable support and the fixed support, and the position changing mechanism comprises a manual position changing device and an electric position changing device. The trailer power assisting device can be manually controlled, the trailer power assisting device can also be electrically controlled, the problem that the trailer cannot be moved due to the fact that the power assisting device fails after one control mode loses efficacy is avoided, and the reliability of the power assisting device is enhanced.

Description

technical field [0001] The invention relates to a trailer booster. Background technique [0002] A trailer or trailer has no power of its own and requires an additional vehicle to tow it. Its short-distance movement and access to the garage require manpower to move and cause trouble. A walker mainly plays a role in assisting movement or exercise, and can effectively solve the above problems. However, there is usually only a manual or electric way to control the clutch between the existing booster and the wheel, and when the only control mode is damaged and invalid, the booster will fail accordingly, causing the vehicle to be shelved, which is very troublesome. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the object of the present invention is to provide a trailer booster, which can not only control its clutch manually, but also control its clutch electrically, avoiding one of the control methods. After the failure, the failure ...
