Embodiment 1

[0022] Embodiment 1 A stringer with a tow hook, including a first tow hook 23 with a hook hole, a second tow hook 24 and a stringer 21, the rear end of the stringer 21 is provided with a crushable induction groove 2. The first towing hook 23 and the second towing hook 24 are respectively arranged at two ends of the longitudinal beam guiding groove 22 .

[0023] refer to figure 2 Arrangement method, first weld a local reinforcement plate inside the bolt installation hole of the vehicle longitudinal beam, and fix the projection welding nut on it, then connect the tow hook 23 and the tow hook 24 with the bolts of the vehicle longitudinal beam 21, and ensure that the two tow hook holes are 3 concentric.

[0024] Such as image 3 In the shown embodiment 2, a stringer with a tow hook, at both ends of the stringer induction groove 22, the first tow hook 23 is connected to the top surface of the stringer 21, and the second tow hook 24 Attached to the side of the stringer.

Abstract

The invention relates to a towing hook not affecting the crushing of a longitudinal beam, which comprises a first towing hook and a second towing hook which are provided with a hook hole respectively. The first towing hook and the second towing hook take the hook holes as the center and are connected in a crossing arrangement mode. The first towing hook and the second towing hook are in a bent shape, a part of the bent shape is a connecting plate connected with the longitudinal beam, while the other part is a main board provided with the hook holes. The longitudinal beam with the towing hookscomprises a longitudinal beam, and a first towing hook and a second towing hook which are provided with hook holes, wherein the rear end of the longitudinal beam is provided with a crushable guide groove, and the first towing hook and the second towing hook are arranged at two ends of the guide groove of the longitudinal beam. Because two towing hooks are arranged at two ends of the guide groove in a triangle crossing arrangement mode, the hook holes of the two towing hooks are concentric; in addition, the two towing hooks have no rigid relation, so that the two towing hooks can move mutually, are not constrained along the longitudinal direction when crash generates, and can substantially reduce the weight.

Description

technical field [0001] The invention relates to a vehicle tow hook, in particular to an automobile tow hook which does not affect longitudinal beam crushing and a longitudinal beam with the tow hook. Background technique [0002] With the continuous progress of the automobile industry, more and more people pay attention to the safety of automobiles. At the same time, many developed countries have also formulated relevant laws and regulations to ensure the safety of automobiles. In the process of car collision, in order to fully deform the engine compartment or trunk to absorb energy, it is generally necessary to pre-design induction grooves on the longitudinal beams to ensure reasonable collapse of the longitudinal beams. However, on some models, due to the needs of the general layout or in order to make the tow hook more firmly installed, the thick and heavy tow hook has to be arranged on the longitudinal beam. Restricted by geometrical space and conditions of use, the in...
