According to a first aspect of the present disclosure, a front tow hook is provided, as shown in fig. 1 to 6, the front tow hook includes a main body 1 and a pin 2, the main body 1 includes two mounting plates 110 arranged at intervals along a vertical direction and extending along a horizontal direction, and a U-shaped fixing plate 120 arranged around the periphery of the two mounting plates 110, three inner sides of the U-shaped fixing plate 120 are attached to the two mounting plates 110, the opposite side of the opening side of the U-shaped fixing plate 120 is attached to the front end of a frame of a vehicle, and the pin 2 is detachably inserted into the two mounting plates 110 and is located on a shaft portion between the two mounting plates 110 for connecting a rope of a trailer.

Through above-mentioned technical scheme, this present disclosure provides a preceding tow hook, through will be used for connecting the round pin axle 2 detachably of trailer rope and place on two mounting panels 110 to around having arranged U-shaped fixed plate 120 simultaneously around the periphery of two mounting panels 110, the inboard three side of this U-shaped fixed plate 120 all laminates and links firmly in two mounting panels 110, with the reinforcing to the tensile strength of trailer rope and the holistic structural strength of tow hook. In the specific operation, the opposite side of the opening side of the U-shaped fixing plate 120 is fixedly connected with the front end of the frame of the vehicle, thereby ensuring stable operation of the trailer hook, and the two mounting plates 110 are arranged at intervals in the vertical direction and each extend in the horizontal direction, so that, when the trailer rope is shaken vigorously to pull the pin shaft 2, especially when the trailer rope swings left and right to pull the pin shaft 2, partial tension can be borne by the two side plates on the opening side of the U-shaped fixing plate 120, thereby avoiding that the pulling force is totally concentrated at the connecting part between the mounting plate and the connecting plate for fixedly connecting the mounting plate as in the prior art, therefore, this disclosure links firmly in mounting panel 110 through the inboard three side of U-shaped fixed plate 120 all laminating, on the one hand can strengthen the structural strength of preceding tow hook self, and on the other hand can also strengthen the anti ability of tearing, especially when the tow rope sways from side to side, can disperse the pulling force that comes from the tow rope. Therefore, the front tow hook provided by the disclosure can solve the problems of lower strength and poorer stability of the tow hook in the related technology, and has the advantages of simple structure and long service life.

It should be noted that, the open side of the U-shaped fixing plate 120 can be referred to as a in fig. 5; the opposite side of the open side of the U-shaped retaining plate can be referred to in fig. 5 at b.

In order to better ensure the overall tensile strength of the front tow hook, in some embodiments, as shown in fig. 1 to 5, the U-shaped fixing plate 120 includes a bottom plate 121 and two side plates 122 respectively disposed at two opposite sides of the bottom plate 121, and the bottom plate 121 is fixedly connected to the front end of the frame of the vehicle, so as to ensure the stable operation of the front tow hook. In addition, two mounting panels 110 set up between two curb plates 122 and all are provided with the mounting hole 111 that supplies round pin axle 2 to pass, and mounting hole 111 arranges between two curb plates 122 placed in the middle, like this, when the trailer rope left and right rocking, can make the pulling force that two curb plates 122 shared unanimously, avoid the atress of two curb plates 122 inhomogeneous, be favorable to guaranteeing the bulk strength of preceding tow car hook, strengthen the holistic tensile strength of preceding tow car hook.

The mounting plate 110 may be configured in any suitable manner according to practical application requirements, for example, in some embodiments, as shown in fig. 1 to 3, the mounting plate 110 has a first side attached to the bottom plate 121 in a fitting manner and a second side opposite to the first side, the second side has an arc portion 112 extending away from the first side, and a center of the mounting hole 111 coincides with a center of the arc portion 112, so as to ensure that the mounting plate 110 has sufficient tensile strength and at the same time, sufficient space for accommodating a rope of a trailer is left between the mounting hole 111 and the bottom plate 121. In addition, when the distance between the mounting hole 111 and the bottom plate 121 is the same, the mounting hole 111 is formed by providing the arc portion 112 on the first side, and the mounting hole 111 is formed by integrally stretching the distance between the first side and the second side, and it is apparent that the weight of the whole mounting plate 110 can be reduced by providing the arc portion 112, thereby reducing the weight of the whole front tow hook and facilitating the mounting and dismounting of the front tow hook. Wherein, the first side can refer to c in fig. 2, and the second side can refer to d in fig. 2.

In some specific embodiments, referring to fig. 1 to 5, the mounting plate 110 has two side edges respectively attached to the two side plates 122, and the length of the side edge is less than or equal to the length of the side edge 122 in the same extending direction, so that the two side edges of the mounting plate 110 are completely attached to the two side plates 122 attached to two sides of the opening of the U-shaped fixing plate 120, and when the trailer rope swings left and right to pull the pin shaft 2, a greater pulling force can be borne by the two side plates 122, so as to enhance the tensile strength of the trailer rope. Fig. 1 exemplarily shows a specific embodiment in which the lengths of the two side edges are equal to the length of the side plate 122 in the same extending direction as the side edges. In addition, the two side edges of the mounting plate 110, which are attached to the two side plates 122, can be referred to as e in fig. 2.

To better ensure the overall tensile strength of the front tow hook, in some embodiments, as shown with reference to fig. 1, the mounting plate 110 has a thickness greater than the thickness of the plate forming the U-shaped securing plate 120.

In the prior art, two mounting plates are usually fixedly connected to a connecting plate which is perpendicular to the two mounting plates, and in this way, when a trailer rope pulls the mounting plates, especially when the trailer rope swings left and right, acting force acts on the joint of the mounting plates and the connecting plate, which easily causes the joint to break. In order to prevent the connection part from being broken, the thickness of the mounting plate and the connecting plate is generally thickened, for example, the mounting plate and the connecting plate in the prior art generally adopt a steel plate with the thickness of 15mm, so that the front tow hook has larger mass. In some embodiments provided by the present disclosure, referring to fig. 1, the thickness of the mounting plate 110 and the U-shaped fixing plate 120 can be made smaller because the U-shaped fixing plate 120 can increase the structural strength and the anti-pulling capability of the front tow coupler itself. For example, the mounting plate 110 may have a thickness of 8mm, the plate constituting the U-shaped fixing plate 120 may have a thickness of 6mm, and the minimum yield strength of the mounting plate 110 and the U-shaped fixing plate 120 is not less than 355 mpa. Through CAE (computer aided engineering) to carry out strength calculation analysis on the front tow hook, when the pin shaft 2 bears 20 kilonewtons of traction force, the maximum stress in the stress area of the front tow hook is only 112 megapascals (the safety factor is greater than 1.5), so that the whole structure of the front tow hook is high in strength, safe and reliable.

In order to further reduce the weight of the front tow hook while ensuring the structural strength and the anti-pulling capability of the front tow hook, in some embodiments, as shown in fig. 1, 3 and 4, the U-shaped fixing plate 120 may be provided with a weight reduction groove 123.

In addition, the U-shaped fixing plate 120 may be fixedly connected to the front body of the vehicle by welding, for example, so that a welding spot may be added through the lightening slot 123 to enhance the stability of the front tow hook on the front body.

The pin 2 may be configured in any suitable manner according to the actual application requirement, for example, in some embodiments, referring to fig. 1 and 6, the pin 2 has a first end and a second end opposite to each other, the first end of the pin 2 has a stopper 210, the second end has a pin hole 220 for passing the locking pin, the pin 2 is vertically inserted through the two mounting plates 110, the stopper 210 is stopped on the upper surface of the mounting plate 110 located at the upper side, and the pin hole 220 is exposed below the mounting plate 110 located at the lower side, so that the pin 2 can be installed on the two mounting plates 110 in a pluggable manner, so that when installing the trailer rope, the pin 2 can be firstly inserted through one mounting plate 110, then the trailer rope is wound on the pin 2, then the pin 2 is inserted through the other mounting plate 110, and finally the locking pin is inserted through the pin hole 220 on the pin 2; when the trailer rope is disassembled, the lock pin is firstly pulled out of the pin hole 220, and then the trailer rope is taken out while the pin shaft 2 is pulled out of the mounting plate 110, so that the better controllability of the front trailer hook is ensured.

According to a second aspect of the present disclosure, there is also provided a vehicle comprising a frame and the front tow hook described above, the front tow hook being attached to a front end of the frame. This vehicle can solve the lower, the relatively poor problem of stability of tow hook intensity among the correlation technique, and has all beneficial effects of above-mentioned preceding tow hook, and this disclosure is no longer repeated here.

In some embodiments, the vehicle may be a passenger vehicle, and the front tow hook is attached to a front end of a frame of the passenger vehicle, and is connected to the tow rope through the front tow hook, thereby playing a role of towing a vehicle body.

The preferred embodiments of the present disclosure are described in detail with reference to the accompanying drawings, however, the present disclosure is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solution of the present disclosure within the technical idea of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.
