Description

Technical Field

[0001] This utility model relates to the field of vehicle accessory mounting structure technology, and more specifically, to a searchlight rotating seat. Background Technology

[0002] Searchlights are a common type of lighting equipment, with advantages such as good focusing effect, high brightness, and long illumination distance. Off-road vehicles and other vehicles are often equipped with searchlights to improve lighting when driving in the wild at night.

[0003] Searchlights are typically mounted on both sides of the hood. To achieve the desired illumination range, the searchlights can usually be rotated to adjust their direction. Currently, there are various adjustment methods, including manual, electric, and hydraulic / pneumatic adjustments. For scenarios where high precision is not required and low cost is a priority, manual adjustment remains the primary method. A common manual adjustment structure includes a mounting bracket, a lamp holder, and an adjusting bolt. The mounting bracket is fixed to the hood, the searchlight is fixed to the lamp holder, and the lamp holder is rotatably connected to the mounting bracket. Tightening the adjusting bolt secures the lamp holder, thus fixing the illumination direction. However, this method requires loosening and tightening the adjusting bolt, which is time-consuming, laborious, and inconvenient. Furthermore, during driving, the adjusting bolt can easily loosen, causing the illumination direction to become unfixed. Utility Model Content

[0004] The purpose of this invention is to provide a searchlight rotating base to overcome the aforementioned defects in the prior art.

[0005] This utility model is achieved through the following technical solution:

[0006] A searchlight rotating base includes a lamp holder and a fixed base, as well as a button and an elastic element. The lamp holder is rotatably mounted on the top of the fixed base. The fixed base has a blind hole, and the side wall of the blind hole has a first anti-rotation tooth. The lamp holder has a through hole at a coaxial position with the blind hole, and the side wall of the through hole has a second anti-rotation tooth. The top of the lamp holder has a limiting structure. The button is located between the limiting structure and the bottom of the blind hole, and the side wall of the button has a third anti-rotation tooth that can simultaneously mesh with the first and second anti-rotation teeth. The elastic element is press-fitted between the bottom of the button and the bottom of the blind hole.

[0007] Optionally, the lamp holder includes an upper seat and a lower seat. The upper seat is connected to the top of the lower seat by fasteners. The top of the fixed seat is provided with a support column, the bottom of the upper seat is provided with an annular platform, and the top of the support column is provided with an annular groove that mates with the annular platform. The outer wall of the support column is provided with a plurality of annular limiting teeth along the axial direction. One end of the lower seat has an arc-shaped structure and the inner side is provided with a first long limiting tooth that meshes with the annular limiting teeth.

[0008] Optionally, one end of the upper seat is provided with an arc-shaped boss, and the arc-shaped boss and the arc-shaped end of the lower seat together enclose the support column.

[0009] Optionally, the inner side of the arc-shaped boss is provided with a first short limiting tooth that mates with the annular limiting tooth. The annular limiting tooth includes a second long limiting tooth and a second short limiting tooth arranged in the circumferential direction. There is an installation gap between the two ends of the second long limiting tooth and the second short limiting tooth. The length of the first long limiting tooth is greater than the length of the installation gap, and the length of the second limiting tooth is less than or equal to the length of the installation gap.

[0010] Optionally, the second short limiting teeth are provided in two sets and correspond one-to-one with the position of the installation gap.

[0011] Optionally, a positioning structure is provided between the upper seat and the lower seat.

[0012] Optionally, the positioning structure includes one or more positioning blocks disposed on the top of the lower seat, and a positioning groove disposed on the bottom of the upper seat and cooperating with the positioning blocks.

[0013] Optionally, the elastic element is a spring.

[0014] The technical solution of this utility model has at least the following advantages and beneficial effects: In this utility model, the button is kept in a state of abutment against the limiting structure under the action of the elastic element. In this state, the third anti-rotation tooth on the side wall of the button simultaneously engages with the first anti-rotation tooth on the fixed seat and the second anti-rotation tooth on the lamp holder, preventing the lamp holder from rotating relative to the fixed seat, thus fixing the illumination direction of the searchlight. When it is necessary to adjust the illumination direction of the searchlight, the button is pressed (the elastic element is compressed and stores energy), and the third anti-rotation tooth on the side wall of the button disengages from the second anti-rotation tooth on the lamp holder (only engaging with the first anti-rotation tooth on the fixed seat), allowing the lamp holder to rotate relative to the fixed seat, thereby realizing the adjustment of the illumination direction of the searchlight. After adjustment, the button is released, and the button resets under the action of the elastic element, fixing the illumination direction of the searchlight. It can be seen that compared with the existing adjustment method, the fixation of the searchlight's illumination direction is more reliable, and the adjustment is more convenient and faster.

Detailed Implementation

[0022] refer to Figures 1-6 A searchlight rotating base includes a lamp holder 1, a fixing base 4, a button 5, and an elastic element 6. Those skilled in the art should understand that in practical applications, the fixing base 4 is fixedly connected (e.g., by screws or bolts) to the hood; the searchlight (not shown) is mounted on the top of the lamp holder 1 by screws (or bolts).

[0023] The lamp holder 1 is rotatably mounted on the top of the fixed base 4. The fixed base has a blind hole 402, and the side wall of the blind hole 402 has a first anti-rotation tooth 4021. The lamp holder 1 and the blind hole 402 are coaxially positioned with a through hole 201, and the side wall of the through hole 201 has a second anti-rotation tooth 2011. The top of the lamp holder 1 has a limiting structure. The button 5 is located between the limiting structure and the bottom of the blind hole 402, and the side wall of the button 5 has a third anti-rotation tooth 501 that can simultaneously engage with the first anti-rotation tooth 4021 and the second anti-rotation tooth 2011. The elastic element 6 is press-fitted between the bottom of the button 5 and the bottom of the blind hole 402. As an option, in this embodiment, the elastic element 6 is a spring. In other embodiments, other elements capable of compressing, storing, and releasing energy (such as rubber cylinders) can be selected.

[0024] Button 5 remains in contact with the limiting structure under the action of the elastic element 6. In this state, the third anti-rotation tooth 501 on the side wall of button 5 simultaneously engages with the first anti-rotation tooth 4021 on the fixed base 4 and the second anti-rotation tooth 2011 on the lamp holder 1. The lamp holder 1 cannot rotate relative to the fixed base 4, thus fixing the beam direction of the searchlight. When it is necessary to adjust the beam direction of the searchlight, button 5 is pressed (the elastic element 6 is compressed and stored). The third anti-rotation tooth 501 on the side wall of button 5 disengages from the second anti-rotation tooth 2011 on the lamp holder 1 (only engaging with the first anti-rotation tooth 4021 on the fixed base 4). The lamp holder 1 can then rotate relative to the fixed base 4, thereby adjusting the beam direction of the searchlight. After adjustment, button 5 is released, and button 5 resets under the action of the elastic element 6, fixing the beam direction of the searchlight. It can be seen that compared with the existing adjustment method, the beam direction of the searchlight is more reliably fixed, and the adjustment is more convenient and faster.

[0025] The method of rotational connection between lamp holder 1 and fixed seat 4 is not limited. As an option, the rotational connection method in this embodiment is as follows: lamp holder 1 includes upper seat 2 and lower seat 3. Upper seat 2 is connected to the top of lower seat 3 by fasteners (such as screws or bolts). Fixed seat 4 is provided with a support column 401 at the top. The bottom of upper seat 2 is provided with an annular platform 202. The top of support column 401 is provided with an annular groove 404 that mates with the annular platform 202. The outer wall of support column 401 is provided with a plurality of annular limiting teeth 403 along the axial direction. One end of lower seat 3 has an arc-shaped structure and the inner side is provided with a first long limiting tooth 301 that meshes with the annular limiting teeth 403. Based on this, it is easy to understand that the aforementioned blind hole 402 is located at the top of the support column 401, and the aforementioned through hole 201 penetrates the upper seat 2. During installation, the elastic element 6 and the button 5 are first placed in the blind hole 402 in sequence, and then the lower seat 3 is brought closer from one side of the support seat so that the first long limiting tooth 301 on the lower seat 3 meshes with the ring tooth (limiting the axial position of the lamp holder 1 as a whole). Finally, the upper seat 2 is fastened to the top of the upper seat 2 so that the ring platform 202 cooperates with the ring groove 404 (limiting the radial position of the lamp holder 1 as a whole).

[0026] The limiting structure on the lamp holder 1 is used to prevent the button 5 from detaching from the lamp holder 1. As an alternative, in this embodiment, the limiting structure is a step provided on the side wall of the through hole 201. Based on this, it is easy to understand that a step is also provided on the side wall of the button 5 to abut against the step on the side wall of the through hole 201, thereby preventing the button 5 from coming out of the top of the through hole 201. In other embodiments, the limiting structure can of course be other forms, such as a retaining ring provided on the top of the through hole 201, the inner diameter of the retaining ring being smaller than the diameter of the button 5, thereby preventing the button 5 from coming out; or several screws are connected in the circumferential direction along the top edge of the through hole 201, the heads of the screws preventing the button 5 from coming out.

[0027] A positioning structure is provided between the upper seat 2 and the lower seat 3. Alternatively, the positioning structure includes one or more positioning blocks 302 located at the top of the lower seat 3, and positioning grooves 203 located at the bottom of the upper seat 2 that cooperate with the positioning blocks 302. For example, in this embodiment, three positioning blocks 302 (their shape is not limited) are provided at the top of the lower seat 3, and three positioning grooves 203 corresponding to the three positioning blocks 302 are provided at the bottom of the upper seat 2. It is easy to understand that providing positioning grooves 203 at the top of the lower seat 3 and providing positioning blocks 302 at the bottom of the upper seat 2 should be equivalent substitutes for the above-described method. In other embodiments, the positioning structure can of course be other methods, such as providing pin holes at at least two sets of corresponding positions at the bottom of the upper seat 2 and the top of the lower seat 3, using positioning pins to achieve positioning.

[0028] In this embodiment, one end of the upper seat 2 is provided with an arc-shaped boss 204. The arc-shaped boss 204 and the arc-shaped end of the lower seat 3 together enclose the support column 401. This arrangement avoids the support column 401 being exposed, making the appearance more aesthetically pleasing. Furthermore, the inner side of the arc-shaped boss 204 is provided with a first short limiting tooth 2041 that mates with the annular limiting tooth 403. The annular limiting tooth 403 includes a second long limiting tooth 4031 and a second short limiting tooth 4032 arranged circumferentially. An installation gap is left between the two ends of the second long limiting tooth 4031 and the second short limiting tooth 4032. The length of the first long limiting tooth 301 is greater than the length of the installation gap (ensuring that after the upper seat 2 and the lower seat 3 are connected and fixed, the lamp holder 1 cannot be separated from the fixed seat 4 axially), and the length of the second limiting tooth is less than or equal to the length of the installation gap (ensuring that the upper seat 2 can be installed normally). Further, two sets of the second short limiting teeth 4032 are spaced apart and correspond one-to-one with the positions of the installation gaps. During installation, after the lower seat 3 is installed from the side of the positioning column (the first long limiting tooth 301 and the annular limiting tooth 403 cooperate), the position of the lower seat 3 is pre-rotated to ensure that when the first short limiting tooth 2041 on the upper seat 2 is aligned with the installation gap and fastened to the top of the support column 401, the positioning groove 203 on the upper seat 2 can be aligned with the positioning block 302 on the lower seat 3.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
