[0002] An automotive lamp adjusting device is generally located inside the engine compartment and includes a ball screw, a reflector, a ball seat and a dimming bolt installed in the lamp housing. Among them, the reflector is matched with the ball seat and the motor rod through a positioning pin seat, switches and adjusts the high and low beam during the driving of the vehicle, and pulls and adjusts the light source angle through the positioning pin seat, the ball head and the telescopic movement of the motor rod, so as to realize the adjustment of the height of the light.

[0003] The positioning pin seat realizes tight positioning through the cooperation of a universal seat and a self-tapping screw. However, the daily bumps and accidental collisions during the driving of the vehicle will cause the displacement of the positioning pin seat and the reflector, and finally change the ground distance of the high and low beams of the automotive lamp. Therefore, it is necessary to rotate the dimming bolt to make the reflector pivot up, down, left or right around the ball seat to complete the dimming operation.

[0004] The engine compartment has a narrow space and many visual blind spots, and it is difficult to rotate the dimming bolt. The dimming device of the prior art needs to add adapter parts and operate according to a specific path and a guiding tool, which is time-consuming and laborious. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a dimming bolt for quickly adjusting automotive lamps, so as to solve the problem that a guiding tool is required to rotate the dimming bolt of the existing automotive lamps.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A dimming bolt for quickly adjusting automotive lamps includes a shoulder and a screw rod portion. One end of the screw rod portion is fixedly connected to the center of the shoulder. The shoulder includes a polygonal plate, a circular plate and a handle portion connected in sequence from the end far away from the screw rod. A groove is opened at the center of the polygonal plate. The handle portion includes a positioning plate and a plurality of handles. One end of each handle is fixedly connected to the circumference of the positioning plate.

[0008] Preferably, the polygonal plate is a hexagonal plate.

[0009] Preferably, the positioning plate is circular in shape, the number of the handles is 3, the handles are evenly connected to the circumference of the positioning plate, and the diameter of the positioning plate is larger than the diameter of the screw rod portion.

[0010] Preferably, a circular groove is axially opened at the center of the hexagonal plate, and a cross groove is axially opened at the center of the circular groove.

[0011] Preferably, the diameter of the hexagonal disk is smaller than that of the circular disk, and the diameter of the circular disk is smaller than that of the positioning plate.

[0012] Preferably, the positioning plate and the plurality of handles are integrally formed by welding with low-carbon steel, and the centers of the polygonal disk, the circular disk and the grip portion are on the same straight line and integrally formed by welding with low-carbon steel.

[0013] Preferably, the handle is in a strip-shaped structure.

[0014] Preferably, a protruding portion facing the screw is provided at one end of the handle away from the positioning plate.

[0015] Preferably, the screw portion is sequentially provided with a smooth portion, an annular groove, a stepped portion and a threaded portion from one end close to the shoulder.

[0023] The following further describes the present utility model with reference to the accompanying drawings:

[0024] As Figures 1 - 3 shown, this embodiment provides a dimming bolt for rapid adjustment of automotive lamps, including a shoulder and a screw rod part. One end of the screw rod part is fixedly connected to the center of the shoulder. The shoulder includes a polygonal disk, a circular disk 2, and a handle part connected in sequence from the end away from the screw rod. A groove is provided at the center of the polygonal disk. The handle part includes a positioning plate 3 and a plurality of handles 4. One end of the handle 4 is fixedly connected to the circumference of the positioning plate 3.

[0025] Specifically, by providing a handle part on the shoulder of the dimming bolt, when it is necessary to adjust the dimming bolt, by holding the handle part with the hand and rotating the handle part, the rotation of the handle will drive the entire dimming bolt to rotate. The rotation of the dimming bolt causes the mirror to be adjusted up, down, left, or right with the ball head seat as the fulcrum, and the light beam is adjusted. Thus, the light adjustment can be completed manually in a narrow headlight space with many visual blind spots without borrowing any guiding tools, saving time and effort. It enables the end user to rotate the dimming bolt in the automotive lamps conveniently and quickly without borrowing any tools.

[0026] In this embodiment, the polygonal disk is a hexagonal disk 1; a circular groove 5 is axially provided at the center of the hexagonal disk 1, and a cross groove 6 is axially provided at the center of the circular groove 5. In practical applications, it can also be provided as a slotted crosshead. If the operating space or the visible range is sufficient, the end user can also choose to use a variety of guiding tools such as a screwdriver and a hexagon wrench to rotate the dimming bolt, providing multiple options for the end user and making the dimming bolt more applicable.

[0027] In this embodiment, the shape of the positioning plate 3 is circular, the number of handles 4 is 3, the handles 4 are evenly connected to the circumference of the positioning plate 3, and the diameter of the positioning plate 3 is larger than the diameter of the screw rod part. This makes it more convenient to rotate the handle 4.

[0028] In this embodiment, the diameter of the hexagonal disk 1 is smaller than the diameter of the circular disk 2, and the diameter of the circular disk 2 is smaller than the diameter of the positioning plate 3. Since the hexagonal disk 1, the circular disk 2, and the handle part are a welded integral structure, setting a gradually increasing diameter structure is for more convenient welding, ensuring the welding quality and also meeting the precision requirements of the parts. By providing the circular disk 2, a larger welding plane is provided for the welding of the handle 4, avoiding deformation during the welding process of the handle 4.

[0029] In this embodiment, the positioning plate 3 and the plurality of handles 4 are integrally formed by welding, and the centers of the polygonal disk, the circular disk 2, and the handle part are on the same straight line and are integrally formed by welding.

[0030] The centers of the polygonal disc, the circular disc 2, and the handle portion are on the same straight line, and the structure is scientifically reasonable. The shoulder of the dimming bolt is integrally welded from low-carbon steel. Specifically, low-carbon steel has excellent compressive resistance, good weldability, and good plasticity, which is suitable for making parts such as bolts and can increase the overall compressive performance of the bolt; the integral welding avoids the scrapping of parts or the generation of forced positioning caused by unqualified dimensions or inaccurate positioning of each assembled part, which causes elastic deformation of each part and large irreversible deformation errors after assembly, thereby having an adverse impact on the structural strength of the component and other economic losses, reducing the requirements for the precision of parts and the assembly precision during the assembly process, and facilitating processing and manufacturing.

[0031] In this embodiment, the handle 4 has a long strip structure, which makes it more convenient when holding the handle 4 by hand.

[0032] In this embodiment, a protruding portion 7 facing the screw is provided at one end of the handle 4 away from the positioning plate 3. By providing the protruding portion 7, the end of the handle 4 is flanged, ensuring the safety of both hands and preventing the phenomenon of cutting hands.

[0033] In this embodiment, the screw portion is sequentially provided with a smooth portion 8, an annular groove 9, a stepped portion 10, and a threaded portion 11 from one end close to the shoulder. The smooth portion 8 passes through the automotive lamp housing and is rotatably connected to the automotive lamp housing for fixing the dimming bolt to the automotive lamp housing. A clamping device is clamped on the annular groove 9 for positioning the automotive lamp housing to prevent the automotive lamp housing from falling off. The outer surface of the stepped portion 10 is a smooth surface for limiting the screw portion, and the threaded portion 11 is used for threaded connection with the transmission component of the automotive lamp housing. After the screw portion is inserted into the screw hole of the transmission component of the automotive lamp housing, the stepped portion 10 avoids the phenomenon of loosening after the dimming bolt is inserted into the screw hole, further improving the stability of the dimming bolt during use. The diameter of the shoulder is larger than the diameter of the screw portion, so that after the screw portion of the dimming bolt is inserted into the screw hole, the shoulder can limit the dimming bolt, preventing the dimming bolt from coming out and enabling the dimming bolt to be used stably.
