Rotatable rear towing hook for vehicle and vehicle

Abstract

The invention belongs to the technical field of vehicle accessories, and particularly discloses a rotatable rear towing hook for a vehicle and the vehicle. The rotatable rear towing hook comprises a towing hook and also comprises a locking nut, a buffer block and a front supporting seat, which are sequentially arranged on the periphery of the towing hook. A rear supporting seat is arranged on theperiphery of the locking nut, one end of the rear supporting seat is connected with the locking nut, the other end extends to the front supporting seat, and the periphery of the rear supporting seat is fixedly connected with a frame through a rear supporting seat fixing bolt. A cavity for accommodating the buffer block is formed between the rear supporting seat and the towing hook; the periphery of the front supporting seat is fixedly connected with the frame through a front supporting seat fixing bolt, an opening used for allowing the towing hook to penetrate through is formed in the middle of the front supporting seat, the front supporting seat is connected with the towing hook in a shaft fit mode, and the towing hook can rotate or slide front and back along the front supporting seat. Onthe premise that the length of the towing hook is not changed, backward pulling force, forward pushing force and vertical force transmitted to the towing hook by a trailer can be borne.

Description

technical field [0001] The invention belongs to the technical field of vehicle accessories, and more specifically relates to a rotatable rear tow hook for a vehicle and a vehicle. Background technique [0002] The rear tow hook of off-road vehicles is used to tow the central axle trailer, etc. When driving on off-road roads, it bears a large force in the up and down direction, so the rear tow hook is required to have high strength. However, the minimum ground clearance and departure angle of off-road vehicles limit the strength of the rear tow hook by increasing its length. The rear towing hook of the existing structure cannot satisfy the above-mentioned requirements simultaneously. [0003] Chinese patent CN102431401A proposes a lubricating and sealing device for a fully-hung traction hook. When the traction hook is used for a central axle trailer or off-road, the support seat and the tail beam of the vehicle frame are prone to failure due to excessive force in the up and ...

AI Technical Summary

Problems solved by technology

The rear towing hook of the existing structure cannot meet the above requirements at the same time

[0003] Chinese patent CN102431401A proposes a lubricating and sealing device for a full-hung traction hook. When the traction hook is used on a central axle trailer or on off-road roads, the supporting seat and the rear beam of the frame are prone to failure due to excessive force in the up and down direction.

When the length of the support seat is increased, the length of the towing hook will increase accordingly, which will cause the problem that the departure angle of the vehicle will become smaller

[0004] Based on the above-mentioned defects and deficiencies, it is urgently needed in this field to further improve the design of the existing towing hook, to build a safe, reliable, and strong enough towing hook. On the premise of not changing the length of the towing hook, by changing the force transmission mode, In order to solve the problem of increasing the strength by increasing the length of the rear towing hook due to the minimum ground clearance and departure angle of the off-road vehicle in the prior art
