Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0032] It should be understood that although the terms first, second, third, etc. may be used to describe in the embodiments of the present application, these descriptions should not be limited to these terms. These terms are only used to distinguish the descriptions. For example, without departing from the scope of the embodiments of the present application, the first may also be referred to as the second, and similarly, the second may also be referred to as the first.

[0033] A hidden uncoupling device provided in the present application includes: a reinforced fixed bracket 1 fixed to the upper end of a floor assembly, a support frame 2 slidably connected to the upper end of the reinforced fixed bracket 1, an uncoupling steering drive structure 3 and a bracket drive structure 4 arranged at intervals on the upper end of the support frame 2; the uncoupling steering drive structure 3 includes: a first drive motor 31 fixed to the upper end of the support frame 2, a first shell 32 fixed to the outside of the output shaft of the first drive motor 31, and a connecting disk 33 sleeved and fixed to the outside of the first shell 32; a first crank 34 and a second crank 35 are arranged at intervals on the circumference of the connecting disk 33; the free end of the first crank 34 is detachably connected to a uncoupling component 36; the free end of the second crank 35 is detachably connected to a trailer shielding cover 37.

[0034] In this embodiment, the unhooking component 36 is fixed to the end of the first crank 34 by a threaded connection; a connecting plate is provided at the rear end of the trailer shielding cover 37, and a fixing hole is provided on the connecting plate for the bolt to pass through, and a threaded hole is provided on the second crank 35 to screw with the bolt.

[0035] It is understandable that when encountering an emergency, such as a vehicle stuck in a quagmire, the user can use a central controller to operate with one button to extend the towing hook component 36 out of the front end of the vehicle, thereby carrying out a rescue operation.

[0036] In this embodiment, the angle between the first crank 34 and the second crank 35 is 90 degrees.

[0037] When in use, the bracket driving structure 4 is started to drive the support frame 2 to move to a specified position toward the rear of the vehicle, and then the unhooking steering driving structure 3 is started. The output shaft of the first driving motor 31 is rotated by a predetermined angle, such as 90°, to drive the first crank 34 to rotate to the initial position of the second crank 35. At this time, the first driving motor 31 stops, and the bracket driving structure 4 is started to drive the support frame 2 to move toward the front of the vehicle, so that the first crank 34 extends out from the front end of the vehicle, and the hook of other vehicles is hooked to the unhooking component 36 to complete the vehicle rescue operation.

[0038] Two sets of guide rails 11 are arranged in parallel at the upper end of the reinforced fixed bracket 1, and correspondingly, a slide groove 21 for cooperating with the guide rails 11 is arranged on the lower surface of the support frame 2; a stop structure for limiting the movement of the support frame 2 is arranged at the upper end of each guide rail 11, and the stop structure includes: a stop block 5 respectively arranged on the front and rear sides of the upper end of the guide rail 11; the advantage of this design is that the moving stroke of the support frame 2 is limited by the two stop blocks 5 at the upper end of the guide rail 11, and the support frame 2 is further prevented from sliding to the outside of the reinforced fixed bracket 1, resulting in product function failure.

[0039] Optionally, limiting brackets 6 are provided on both sides of the left and right sides of the reinforced fixed bracket 1; the limiting bracket 6 is an inverted L-shaped structure as a whole, and the lower end surface of the horizontal upper end of the limiting bracket 6 is in sliding contact with the support frame 2; specifically, the two limiting brackets 6 and the reinforced fixed bracket 1 are an integrally formed structure; the advantage of this design is that through the design of two limiting brackets 6, the connection stability between the support frame 2 and the reinforced fixed bracket 1 is increased, so that the support frame 2 can withstand a large external pulling force without becoming unstable.

[0040] Furthermore, reinforcing ribs are provided at the inner corner points where the limiting bracket 6 is connected to the reinforcing fixing bracket 1 , and the design of the reinforcing ribs can prevent cracks from occurring at the bottom of the limiting bracket 6 .

[0041] Optionally, the support driving structure 4 is used to drive the support frame 2 to slide on the upper end of the reinforced fixed support 1; the support driving structure 4 includes: a second driving motor 41 fixed to the upper end of the support frame 2, a driving gear 42 arranged at the end of the output shaft of the second driving motor 41, and a transmission rack 43 transmission-connected to the driving gear 42; wherein, the output shaft of the second driving motor 41 passes through the support frame 2 and is fixed with a driving gear 42 by a key connection; one side of the transmission rack 43 is fixed to the guide rail 11, and the other side is provided with a transmission tooth meshing with the driving gear 42; it can be understood that in this embodiment, the driving gear 42 is driven to rotate by the second driving motor 41, and the driving gear 42 is meshed with the transmission rack 43, thereby pushing the support frame 2 to move along the upper end of the reinforced fixed support 1; the present application ensures the stability of the movement of the support frame 2 through the support driving structure 4, and ensures that the support frame 2 can withstand a large pulling force without instability.

[0042] Optionally, a sensing device 7 for detecting the position of the support frame 2 is provided on the front and rear sides of the middle part of the upper surface of the reinforced fixing bracket 1; the sensing device 7 is a position sensor or a proximity sensor; the moving position of the support frame 2 can be identified through the sensing device 7; the sensing device 7 is connected to the central controller by signal.

[0043] Furthermore, the front and rear ends of the bottom of the support frame 2 may be provided with an identification portion for detection by a sensing device; wherein the identification portion may be a metal bar or an identification hole; the advantage of this design is that it further improves the position detection accuracy of the support frame 2, but the disadvantage is that the cost is increased.

[0044] It can be understood that the present application realizes the extension of the towing hook from the front end of the vehicle and the hiding function of the vehicle shielding cover 37 through the linkage cooperation between the unhooking steering drive structure 3 and the bracket drive structure 4, thereby avoiding the situation in which the driver and passengers are unable to quickly find the unhooking position in an emergency, affecting the towing and rescue work.
