Problems solved by technology

[0002] With the continuous change of people's life style, more and more people have more demands on the mounting performance of the car. The trailer coupler installed on the existing car includes the main body and the tow hook, and the main body is fixed on the body of the car. , the main body is provided with a rotating shaft for driving the tow hook to rotate synchronously. According to actual needs, the tow hook is turned to the folded position below the vehicle body or to the unfolded position outside the vehicle body for mounting. Because the tow hook is in the unfolded position in the prior art , there is no locking mechanism to lock the shaft to prevent it from turning, so it will shake when the tow hitch is hitched, thereby reducing the hitch performance of the trailer coupler

Embodiment 1

[0040] refer to Figure 1 to Figure 8 As shown, the trailer coupler in this embodiment includes a main body and a trailer hook 100, the main body is fixed on the anti-collision beam of the vehicle body, the main body includes a driving shaft 200, a locking member 300, a transmission disc 400 and a driven shaft 500, from The driving shaft 500 is connected with the tow hook 100 and rotates synchronously. The driving shaft 200 drives the transmission disc 400 to idle, so that the locking member 300 locks or unlocks the rotation of the driven shaft 500. When the locking member 300 unlocks the rotation of the driven shaft 500, The driving shaft 200 drives the driven shaft 500 to rotate through the transmission disc 400, so that the tow hook 100 can be switched between the folded position and the unfolded position. When the tow hook 100 is in the folded position or the unfolded position, the locking member 300 locks the turn.

[0041] In this embodiment, when the drive shaft 200 dr...

Embodiment 2

[0057] Such as Figure 9 As shown, compared with Embodiment 1, the difference of this embodiment is that teeth 320 are provided on the arc surface of the claw, and tooth grooves meshing with the teeth are provided on the outer peripheral side of the transmission disc 400, preferably the transmission disc 400 is a gear, and the tooth groove forms the driving groove 410 . Such a design can also push the pawl out of the locking groove 510 through the groove wall of the driving groove 410 .

Embodiment 3

[0059] Compared with Embodiment 1 and Embodiment 2, the difference of this embodiment is that no motor assembly is provided in the housing 700 in this embodiment, and in this case, one end of the drive shaft 200 extends out of the housing 700 In addition, the user can also drive the drive shaft 200 to rotate by turning the end of the drive shaft 200 protruding out of the housing 700 with a wrench or by hand, so that the tow hook 100 can be switched between the folded position and the unfolded position, thereby reducing the manufacturing cost of the product. Cost, but also to avoid the phenomenon that the product cannot be used normally due to electrical failure.

Abstract

The invention discloses a trailer coupler with good mounting performance, and solves the technical problem that in the prior art, a trailer hook is prone to shaking when located at an unfolding position or a folding position. The trailer coupler comprises a main body and the trailer hook, the main body is fixed to a vehicle body, the main body comprises a driving shaft, a locking piece, a transmission disc and a driven shaft, the driven shaft is connected with the trailer hook and rotates synchronously with the tow hook, the driving shaft drives the transmission disc to idle so that the locking piece can unlock or lock rotation of the driven shaft, and when the locking piece unlocks rotation of the driven shaft, the driving shaft drives the driven shaft to rotate through the transmission disc, the trailer hook can be switched between the folding position and the unfolding position, and when the trailer hook is located at the folding position or the unfolding position, the locking piece locks rotation of the driven shaft.

Description

【Technical field】 [0001] The invention relates to the technical field of trailer couplers, in particular to a trailer coupler with good loading performance. 【Background technique】 [0002] With the continuous change of people's lifestyle, more and more people have more demands on the mounting performance of the car. The trailer coupler installed on the existing car includes the main body and the tow hook, and the main body is fixed on the body of the car. , the main body is provided with a rotating shaft for driving the tow hook to rotate synchronously. According to actual needs, the tow hook is turned to the folded position below the vehicle body or to the unfolded position outside the vehicle body for mounting. Because the tow hook is in the unfolded position in the prior art , there is no locking mechanism to lock the shaft to prevent it from turning, so it will shake when the tow hitch is hitched, thereby reducing the hitch performance of the trailer coupler. 【Content ...
