Problems solved by technology
In the first way, when the tow hook is stressed, it is easy to break at its welding position, and the traction force it can withstand is very small; in the second way, the traction force received by the tow hook is greatly improved, but the anti-collision The stress form of the beam body is relatively simple. When the tow hook is subjected to traction, it may cause the anti-collision beam body to deform and fail due to concentrated force.

Embodiment
[0027] This embodiment is a tow hook installation device, which is used to install the tow hook on the car.
[0028] Such as figure 1 and Figure 5 As shown, it includes the existing anti-collision beam body 1 and the connecting column 2 connected with the tow hook. The tow hook is directly connected with the anti-collision beam body 1 .
[0029] Such as Figure 2 to Figure 4 As shown, the anti-collision beam body 1 is made by punching a metal plate, and a groove 11 is provided on it for enhancing strength, and a reinforcing plate 5 is spot welded in the groove 11, and the reinforcing plate 5 is attached to the Inside the groove 11 , a flange 51 protruding from the groove 11 is provided on the reinforcing plate 5 . By selecting the reinforcing plate 5 of corresponding material and thickness, the anti-collision beam body 1 can be effectively supported auxiliaryly, and its strength can be improved. After the reinforcing plate 5 and the anti-collision beam body 1 are welded,...

The invention discloses a mounting device for a tow hook. The mounting device comprises an anti-collision beam body, a connecting post and a stiffening plate, wherein the connecting post is connected with the tow hook, the stiffening plate is fixed on the anti-collision beam body, a protruding connecting surface separated from the surface of the anti-collision beam body and at least two connecting lugs positioned on two sides of the connecting surface are arranged on the stiffening plate, two ends of the connecting post are fixedly connected with the anti-collision beam body and the connecting surface respectively, and each connecting lug is fixedly connected on the anti-collision beam body. According to the mounting device, the stiffening plate is arranged additionally, so that the stability of the anti-collision beam body and the connecting post can be improved, when the tow hook is under the action of bending moment, the stiffening plate can provide opposite moment for the anti-collision beam body, and torsional deflection of the anti-collision beam body cannot occur easily. The mounting device is applicable to various automobiles and used for mounting front or back tow hooks.
Description
technical field [0001] The invention belongs to the field of automobiles, and relates to an automobile accessory, in particular to a tow hook installation device. Background technique [0002] For cars with a load-bearing body, there are two common installation forms of the tow hook: one is directly fixed on the body floor by spot welding, and the other is threaded on the anti-collision beam body of the car. In the first way, when the tow hook is stressed, it is easy to break at its welding position, and the traction force it can withstand is very small; in the second way, the traction force received by the tow hook is greatly improved, but the anti-collision The stress form of the beam body is relatively simple. When the tow hook is subjected to traction force, the anti-collision beam body may be deformed and fail due to concentrated force. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tow hitch installatio...
