The present utility model relates to vehicle lamp adjustment systems, and more particularly to an actuation assembly for a vehicle lamp adjustment system. Fig. 1 is a schematic view of an embodiment of an actuating assembly of the lamp adjustment system of the present utility model, the actuating assembly including a motor 20 and a drive shaft 40 coupled to the motor 20.

The motor 20 includes a stator 22 and a rotor 24 rotatable relative to the stator 22. In the illustrated embodiment, the motor 20 is an inner rotor motor and the rotor 24 is rotatably disposed in the center of the stator 22. The rotor 24 includes a rotating shaft 26, a connecting hole 28 is provided in the rotating shaft 26, and an internal thread 29 is formed on a wall of the connecting hole 28. In the illustrated embodiment, the connection hole 28 is a through hole penetrating the rotation shaft 26 in the axial direction; in other embodiments, the connecting hole 28 may be a blind hole that does not penetrate the shaft 26. In addition, in the illustrated embodiment, the female screw 29 is formed in the middle of the wall of the connection hole 28; in other embodiments, the internal threads 29 may also be distributed throughout the wall of the connecting bore 28.

As shown in fig. 2, the driving shaft 40 is an elongated shaft structure and includes a first connecting end 42 and a second connecting end 44 opposite to each other, wherein the first connecting end 42 is used for connecting with the motor 20, and the second connecting end 44 is used for connecting with a vehicle lamp. The outer wall of the first coupling end 42 is formed with external threads 421, the external threads 421 mating with the internal threads 29 of the spindle 26. When assembled, the first connecting end 42 of the driving shaft 40 is inserted into the connecting hole 28 of the rotating shaft 26, and the first connecting end and the connecting end are connected through the matching screw threads of the internal threads 29 and the external threads 421. When the motor 20 is started, the rotating shaft 26 is driven to rotate, and in the rotating process, the rotating shaft 26 drives the driving shaft 40 screwed with the rotating shaft to linearly move in the axial direction, so that the lamp is driven to perform light adjustment.

In this embodiment, the middle portion of the driving shaft 40 is provided with a stopper 46, and the stopper 46 integrally extends radially outward from the outer wall of the driving shaft 40. The stopper 46 has an outer diameter larger than the diameter of the drive shaft 40, and limits displacement of the drive shaft 40 in the axial direction. As shown in fig. 2 to 3, the stopper 46 is formed with a notch 461 to be divided into a plurality of block structures in the circumferential direction. In other embodiments, the stop 46 may be a complete annular structure. The opposite sides of the drive shaft 40 form a first plane 48, respectively, such that the drive shaft 40 has a generally racetrack-shaped cross-section. Similarly, the opposite sides of the stop 46 respectively form a second plane 49, and the second plane 49 is disposed parallel to the first plane 48.

As shown in fig. 1, the stator 22 of the motor 20 is formed with a sleeve 221 extending axially outwardly, and the sleeve 221 is located at an axially outer end of the rotating shaft 26 and is disposed coaxially with the rotating shaft 26. The sleeve 221 is centrally provided with a perforation 223, the perforation 223 having a bore diameter greater than the diameter of the second connecting end 44 of the drive shaft 40 but less than the diameter of the stop 46. When assembled, the second connection end 44 extends out of the motor 20 through the through hole 223 and is connected with the vehicle lamp. The stop 46 of the drive shaft 40 is located inside the sleeve 221, and the stop 46 is separated from the sleeve 221 when the drive shaft 40 moves toward the inside of the motor 20; when the drive shaft 40 moves a certain distance outward of the motor 20, the stopper 46 abuts against the sleeve 221, and the displacement of the drive shaft 40 is restricted.

In this embodiment, the second connecting end 44 of the driving shaft 40 is connected with a ball head 50, the connecting component of the vehicle lamp is configured with a ball seat matched with the ball head 50, and the vehicle lamp can be adjusted in all directions by matching the ball head 50 with the ball seat to form a universal ball head, so that the light can meet the use requirements of various road conditions. The ball 50 and the second connecting end 44 of the driving shaft 40 are preferably fixed by riveting, in the illustrated embodiment, the outer wall of the second connecting end 44 is formed with knurling 441, and the knurling 441 not only can improve the fatigue resistance of the second connecting end 44, but also can increase the anti-skid performance, improve the stability of connection with the ball 50, and avoid the ball 50 falling off in the use process.

The drive shaft 40 and the stopper 46 of the present utility model are integrally formed by die casting (DIE CASTINGS) using zinc alloy material. Die casting is similar to injection molding in that a zinc alloy melt is pressed with high pressure into a mold having a correspondingly shaped cavity until the drive shaft 40 and stop 46 are solidified. The driving shaft 40 and the stop part 46 are molded at one time in a die casting mode, so that the manufacturing process can be simplified to the greatest extent, and the formed driving shaft 40 and stop part 46 have flat surfaces, good tensile strength and impact resistance. The first flat surfaces 48 on both sides of the driving shaft 40 and the second flat surfaces 49 on both sides of the stop portion 46 facilitate the selection of parting lines and the establishment of parting surfaces, and facilitate the die casting of the driving shaft 40.

The driving shaft 40 and the stop portion 46 are made of zinc alloy material and are integrally formed by die casting. Compared with the prior art, the driving shaft is made of copper alloy materials, the shaft lever is firstly machined and molded in the production process, then threads are formed on the outer surface of the shaft lever, then a coating is covered on the outer surface of the shaft lever, then a stop part is formed on the shaft lever in an injection molding mode, the whole process steps are numerous, the produced driving shaft has large weight and high cost, the manufacturing process can be simplified to the greatest extent, and the formed driving shaft 40 and the stop part 46 have flat surfaces, good tensile strength and impact resistance; the die casting process is suitable for mass production of small and medium-sized products, and the cost required for die casting the driving shaft 40 can be effectively controlled, so that the cost of the car lamp adjusting system is reduced to a certain extent.

It should be noted that the above examples merely represent preferred embodiments of the present utility model, and the description thereof is more specific and detailed, but should not be construed as limiting the utility model. It should be noted that it will be apparent to those skilled in the art that modifications and improvements can be made without departing from the spirit of the utility model, such as combining different features of the various embodiments, which are all within the scope of the utility model.
