[0021] It should be noted that, in the following embodiments, the “first”, “second” and “third” mentioned do not represent an absolute distinction in structure and / or function, nor do they represent a sequence of execution, but are merely for the convenience of description.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field to which the present invention belongs. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0023] like Figures 1 to 5 As shown, the utility model provides a trailer hook cover opening and closing device, comprising a lock hook 2 arranged on a trailer hook cover plate 1 and an actuator 4 for clamping the lock hook 2 when the trailer hook cover plate 1 is closed, the actuator 4 is configured to apply a force in a second direction to the lock hook 2 after receiving a force in a first direction, and push the trailer hook cover plate 1 to move linearly in a direction away from the actuator 4, so as to realize the opening of the trailer hook cover plate 1, and the first direction and the second direction are two opposite directions. At least one lock hook 2 is provided, and the number of actuators 4 is the same as the number of lock hooks 2.

[0024] Specifically, if Figures 1 to 5 As shown, the actuator 4 includes a housing 5, a lock tongue 8 movably disposed on the housing 5 and matched with the lock hook 2, and two clamping claws 7 disposed on the housing 5 and used to clamp the lock hook 2, and the two clamping claws 7 are distributed on both sides of the lock tongue 8. The housing 5 is a hollow structure, and the lock tongue 8 is movably disposed on the housing 5. One end of the lock tongue 8 is located inside the housing 5, and the other end of the lock tongue 8 is used to contact the end of the lock hook 2. One end of the clamping claw 7 is located inside the housing 5, and the other end of the clamping claw 7 is used to apply a clamping force to the lock hook 2. The lock hook 2 is fixedly connected to the trailer hook cover 1, and a first mounting hole for accommodating the trailer hook cover 1 is provided on the bumper 3 of the vehicle. When the trailer hook cover 1 is closed, the trailer hook cover 1 is located in the first mounting hole, and the clamping claw 7 of the actuator 4 clamps the lock hook 2.

[0025] like Figure 2 As shown, a guide surface for contacting the lock hook 2 is provided on the clamping jaw 7, and the guide surface is an arc surface. When the trailer hook cover 1 moves along the first direction, after the lock hook 2 contacts the guide surface of the clamping jaw 7, the two clamping jaws 7 can be pushed to swing, so that the two clamping jaws 7 are opened, and then the lock hook 2 can be embedded between the two clamping jaws 7 and contact the lock tongue 8.

[0026] The clamping jaw 7 is rotatably connected to the housing 5, and the actuator 4 further comprises a locking mechanism disposed on the housing 5 and connected to the two clamping jaws 7 and the locking tongue 8. The locking mechanism mainly comprises a movably disposed slider and a connecting rod connected to the slider and the clamping jaw 7. Two connecting rods are disposed, one end of the two connecting rods in the length direction is rotatably connected to the slider, and the other end of the two connecting rods in the length direction is rotatably connected to the two clamping jaws 7 respectively. The slider, the connecting rod and the clamping jaw 7 constitute a slider connecting rod mechanism. When the slider moves, the clamping jaw 7 is driven to rotate by the connecting rod. The slider and the locking tongue 8 are on the same straight line, and the moving directions of the slider and the locking tongue 8 are perpendicular to the rotation center line of the clamping jaw 7 in space. A first compression spring and a second compression spring are disposed in the housing 5. The first compression spring is used to apply an elastic force to the locking tongue 8, that is, to generate a force in the second direction. Under the action of the elastic force, the locking tongue 8 has a tendency to move toward the outside of the housing 5, so that the locking tongue 8 can push the lock hook 2 to move. The second compression spring is used to apply an elastic force to the slider, and the slider is located between the first compression spring and the second compression spring. In the initial state, there is a certain distance between the locking tongue 8 and the slider, the first compression spring and the second compression spring are in an extended state, and the two clamping jaws 7 are in a closed state.

[0027] In this embodiment, Figure 5 As shown, three locking hooks 2 and three actuators 4 are provided, and all the actuators 4 are distributed circumferentially outside the avoidance hole provided on the vehicle bumper 3, and the avoidance hole is used to expose the trailer hook after the trailer hook cover 1 is opened.

[0028] Preferably, a limiting structure is provided in the first mounting hole to guide the trailer hook cover plate 1 to move linearly, and the limiting structure includes limiting ribs provided on the inner wall surface of the first mounting hole, and a guide groove is provided on the outer wall surface of the trailer hook cover plate 1 for the limiting ribs to be embedded.

[0029] When the trailer hook cover 1 is opened, Figure 4In the force application area shown, a force along the first direction is applied to the trailer hook cover 1. After the force is applied, the trailer hook cover 1 moves inward, the lock hook 2 contacts the lock tongue 8, and pushes the lock tongue 8 to move. The first compression spring is compressed. After reaching the unlocking stroke of the actuator 4, the lock tongue 8 contacts the slider, and the locking mechanism in the actuator 4 performs a corresponding action. The lock tongue 8 pushes the slider to move, the second compression spring is compressed, and the clamping claw 7 rotates at the same time. After the clamping claw 7 is separated from the lock hook 2, under the action of the reaction force generated by the first compression spring, the lock tongue 8 moves in the opposite direction, and the lock tongue 8 applies a force along the second direction to the lock hook 2. Under the push of the reaction force, the trailer hook cover 1 moves outward, and the trailer hook cover 1 moves linearly along the second direction toward a position away from the actuator 4, and the trailer hook cover 1 is opened. At the same time, the circumferential limiting structure of the trailer hook cover 1 can ensure that the trailer hook cover always maintains a safe gap with the surrounding area during the process of being disengaged to avoid collision. Since the movement direction and the force application direction are parallel, the trailer hook cover 1 is not restricted by shape.

[0030] like Figure 2 and Figure 3 As shown, two hooks 6 are arranged outside the housing 5, and the two hooks 6 are arranged on two opposite outer wall surfaces of the housing 5. A slot for the hooks 6 to be inserted is arranged on the bumper 3 of the vehicle. The bumper 3 is also provided with a second mounting hole 9 for accommodating the actuator 4, and the second mounting hole 9 is connected to the first mounting hole. The slot is a groove arranged on the inner wall surface of the second mounting hole 9. The actuator 4 is connected to the bumper 3 by the cooperation between the hook 6 and the slot, and the installation is convenient.

[0031] The utility model also provides a vehicle, including the trailer hook cover opening and closing device of the above structure. The specific structure of the trailer hook cover opening and closing device can be referred to Figures 1 to 5 Since the vehicle of the utility model includes the trailer hook cover opening and closing device in the above embodiment, it has all the advantages of the above trailer hook cover opening and closing device.

[0032] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
