One end of the thirteenth spring 84 is fixedly connected to the fourth slider 632, and the other end is fixedly connected to the third slot 71.
In addition, the third clamping groove 71 can limit the moving distance of the fourth slider 632 and the fifth slider 211, so as to avoid the towed member from generating larger inertial impact.
In one embodiment, the first and second rods 62, 63 further comprise a fixed stage 66; the trailer hook further comprises a fifth elastic member 65, one end of the fifth elastic member 65 is connected to the fixing stand 66 of the first rod 62, and the other end of the fifth elastic member is connected to the fixing stand 66 of the second rod 63.
Specifically, as shown in fig. 14 and 15, the angle between the first lever 62 and the second lever 63 is changed during the rotation of the first lever 62 and the second lever 63, so that the energy of the inertial impact applied to the vehicle can be further consumed by the fifth elastic member 65, thereby further improving the drivability and riding comfort of the vehicle.
Wherein the fifth elastic member 65 is a spring.
Of course, the first elastic member 3, the second elastic member 5, the third elastic member, the fourth elastic member 8 and the fifth elastic member 65 according to the embodiment of the present application may be hydraulic cylinders or pneumatic cylinders, and those skilled in the art may select according to actual needs, which is not limited herein.
In one embodiment, the trailer hook comprises a first shock absorbing portion 1, a second shock absorbing portion 4, a third shock absorbing portion 6 and a trailer hook body 7.
Specifically, as shown in fig. 1, the trailer hook is connected with the vehicle through the second damping portion 4, the supporting frame 423 of the second damping portion 4 is fixedly connected with the fixing plate 11 of the first damping portion 1, the first damping portion 1 is slidably connected with the rotating assembly 2, the guiding boss 22 of the rotating assembly 2 is slidably connected with the third damping portion 6, the third damping portion 6 further comprises a first rod 62 and a second rod 63, the rotating assembly 2 is connected with the trailer hook body 7 through the first rod 62 and the second rod 63, and the trailer hook body 7 is connected with the towed piece, so that the problems that the driving performance of the vehicle and the comfort of the vehicle are poor due to the fact that the vehicle is influenced by the up-down shaking of the towed piece, the relatively large reaction torque is brought to the vehicle due to uneven road surface, and the inertia impact in the vehicle braking direction is generated.
According to another embodiment of the present application, there is provided a vehicle including a trailer hook according to an embodiment of the present application.
The foregoing embodiments mainly describe differences between the embodiments, and as long as there is no contradiction between different optimization features of the embodiments, the embodiments may be combined to form a better embodiment, and in consideration of brevity of line text, no further description is given here.
While certain specific embodiments of the utility model have been described in detail by way of example, it will be appreciated by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the utility model. It will be appreciated by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the utility model. The scope of the utility model is defined by the appended claims.
