[0023] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0024] Reference Figures 1 to 6 As shown, in order to achieve the above objectives, the present invention provides the following technical solution: a headlamp, including a lamp body 1 and a mounting frame 2, the mounting frame 2 being hinged to the back of the lamp body 1, and an angle limiting structure 3 being provided between the mounting frame 2 and the lamp body 1;

[0025] The angle limiting structure 3 includes a limiting groove 31, a limiting member 32, and a limiting spring 33. Multiple limiting rods 4 are arranged sequentially in the limiting groove 31 along the rotation direction of the mounting frame 2. A limiting gap 5 is formed between two adjacent limiting rods 4. The limiting member 32 is inserted into the limiting gap 5 by the limiting spring 33.

[0026] like Figure 6 As shown, multiple sets of limiting gaps 5 are formed, which can meet the limiting adjustment of the mounting bracket 2 at various angles.

[0027] The design of this utility model utilizes the elastic force of the limiting spring 33 to engage the limiting member 32 into the limiting gap 5, thereby abutting against the limiting rods 4 on both sides, which serves to limit the rotation of the mounting bracket 2. This structure is simple, and the limiting spring 33 provides a stable limiting force, making it easy to operate and allowing for various limiting angles.

[0028] The present invention is further configured such that: the limiting groove 31 is provided on the mounting bracket 2, the lamp body 1 is provided with a mounting groove 11 at the position corresponding to the limiting groove 31, and the limiting member 32 is slidably connected to the mounting groove 11 through the limiting spring 33.

[0029] The design of this structure allows the mounting slot 11 to be opened in the body of the lamp body 1, or as... Figure 2 As shown, a block-shaped component is provided at one end of the lamp body 1, and the mounting groove 11 is provided at the upper end of the block-shaped component.

[0030] The present invention is further configured such that: the limiting member 32 includes a mounting part 321, a limiting head 322 and a guide rod 323, the guide rod 323 and the limiting head 322 are respectively disposed at both ends of the mounting part 321, and the limiting spring 33 is sleeved on the guide rod 323.

[0031] Two sets of guide rods 323 and limit springs 33 are provided.

[0032] like Figure 5As shown, the design of this structure can provide a stable thrust to the limiting member 32 through the limiting spring 33, so that the limiting head 322 can be stably inserted into the limiting gap 5.

[0033] The present invention is further configured such that: a limiting part 6 with a triangular prism structure is provided at one end of the limiting head 322 away from the mounting part 321. Guide slopes 41 are provided on both sides of the limiting rod 4 facing the lamp body 1.

[0034] like Figure 5 and Figure 6 As shown, the design of this structure can ensure the stability of the limit while also facilitating the rotation of the mounting bracket 2. During the rotation of the mounting bracket 2, the limit part 6 can move from one limit gap 5 to another limit gap 5 through the cooperation of the limit part 6 and the guide slope 41.

[0035] The present invention is further configured such that: two sets of rotating blocks 12 are provided on the lamp body 1, the rotating blocks 12 are provided with rotating grooves, two sets of rotating rods 21 are correspondingly provided on the mounting bracket 2, and the angle limiting structure 3 is provided between the two rotating blocks 12.

[0036] The present invention is further provided with a slot 22 on the side of the mounting bracket 2 away from the lamp body 1. The design of the slot 22 facilitates fixing the lamp body 1 to the cap body with the corresponding structure through the mounting bracket 2.

[0037] The present invention is further configured such that: the lamp body 1 includes multiple sets of lamp sources 13 and control switches 14, and the control switches 14 are used to switch the modes of the lamp sources 13.

[0038] The design of this structure allows for the integration of multiple light source modes within existing lighting fixtures, enabling switching between these modes to meet the lighting needs of different scenarios.

[0039] Alternatively, a sensor-controlled light source mode can be designed, using common sensors such as Hall effect sensors, infrared sensors, or laser sensors for remote light source control. The specific structure is the existing light source control structure, which will not be elaborated here.
