Through the setting of the support frame 9, the large gear 33 and the transmission gear 34 can be supported, which can make the large gear 33 and the transmission gear 34 more stable when rotating.

[0026] Example 2:

[0027] Figure 1-5The utility model shows a hidden electric trailer hook of an embodiment, which includes: a hollow groove opened on the front side of the vehicle body 1: a cover 2 is slidably connected to the front side of the vehicle body 1, a transmission assembly 3 is provided in the inner cavity of the hollow groove, and the transmission assembly 3 includes a support rod 31 rotatably connected to the inner cavity of the hollow groove, the top of the support rod 31 is fixedly connected to the driving gear 32 by bolts, the surface of the driving gear 32 is meshed with a large gear 33, and the surface of the large gear 33 is meshed with a transmission gear 34, and the rear side of the cover 2 is fixedly connected to a rack 35, and the rack 35 is engaged with the transmission gear 34. The surfaces of the movable gear 34 are meshed, and the surface of the support rod 31 is fixedly connected to the bracket 10, which is located directly below the bevel gear 7. A spherical tow hook 11 is welded to the top of the front side of the bracket 10, and the upper and lower sides of the inner cavity of the hollow groove are fixedly connected to the limit strips 12. The rear of the upper and lower sides of the cover 2 are provided with limit slots, and the surface of the limit strip 12 is slidably connected to the inner cavity of the limit slot. Through the setting of the limit strip 12, the cover 2 can be limited and supported during the sliding process of the cover 2, so that the cover 2 can remain stable during sliding.

[0028] Working principle: When the present invention is used, the user controls the motor 5 to operate through the sensor 8, and then the motor 5 drives the bevel gear 7 to rotate to the left through the bevel gear 6. At the same time, under the support and connection of the support rod 31, the driving gear 32 is driven to rotate to the left. Because the driving gear 32, the large gear 33 and the transmission gear 34 are in a state of mutual meshing, the driving gear 32 drives the large gear 33 to rotate to the right in the opposite direction, and drives the transmission gear 34 to rotate to the left through the large gear 33, and then the transmission gear 34 drives the cover 2 to slide to the left through the rack 35, so that the cover 2 is unfolded, and the bracket 10 and the ball tow hook 11 are rotated to the left, and the ball tow hook 11 is protruded from the surface of the vehicle body 1, which can facilitate the use of the ball tow hook 11 and the use and hiding of the hidden tow hook.

[0029] In summary, the hidden electric trailer hook drives the driving gear 32 to rotate leftward through the bevel gear 7. Since the driving gear 32, the large gear 33 and the transmission gear 34 are in a state of mutual meshing, the transmission gear 34 drives the cover 2 to slide leftward through the rack 35, and the spherical trailer hook 11 protrudes from the surface of the vehicle body 1, thereby facilitating the use of the spherical trailer hook 11 and facilitating the use and hiding of the hidden trailer hook.
