Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive technology, and in particular to a touch-sensitive interior dome light for automobiles. Background Technology
[0002] An automobile is a land transportation vehicle powered by an internal combustion engine. It usually has four or more wheels and is used to transport people or various goods. Due to the rapid development at present, people are paying more and more attention to the practicality of the devices and accessories inside the car, including the touch dome light inside the car.
[0003] When a vehicle is parked in different environments, the user will have different needs regarding the brightness of the lights. However, most existing car interior touch dome lights are controlled by a switch or button, without any brightness adjustment function. Therefore, we propose a car interior touch dome light to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide an automotive interior touch-sensitive dome light to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A car interior touch dome light includes a mounting box, the inside of which is provided with a connecting mechanism, the outer surface of which is provided with a control mechanism, the outer surface of which is fixedly connected with an adjustment mechanism, the outer surface of which is provided with a lighting lamp, and the outer surface of which is provided with a wire through hole.
[0007] In a further embodiment, the connecting mechanism includes two first bearings, the inner rings of which are jointly fixedly connected to a threaded rod.
[0008] In a further embodiment, a first gear is fixedly connected to the outer surface of the threaded rod, and a threaded cylinder is threadedly connected to the outer surface of the threaded rod.
[0009] In a further embodiment, a connecting block is fixedly connected to the outer surface of the threaded cylinder, and an insulating rod is fixedly connected to the outer surface of the connecting block.
[0010] In a further embodiment, the control mechanism includes a second bearing, the inner ring of which is fixedly connected to a rotating rod.
[0011] In a further embodiment, a knob is fixedly connected to one end of the rotating rod, and a second gear is fixedly connected to the other end of the rotating rod, the outer surface of the second gear meshing with the outer surface of the first gear.
[0012] In a further embodiment, the adjustment mechanism includes two insulating plates, and a resistor rod is fixedly installed on one side of the two insulating plates that are close to each other. An adjustment element is slidably connected to the outer surface of the resistor rod.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This device utilizes a knob to rotate a lever, which in turn drives a second gear. The second gear, in turn, drives a first gear, which in turn drives a threaded rod, causing the threaded cylinder to move horizontally. An adjustable component allows for adjustment of the resistance output of the resistance rod, thereby regulating the resistance of the lighting lamp and controlling its brightness. This solves the problem of not being able to adjust the brightness of the lighting lamp when it is directly turned on or off using a switch or button.
[0015] The installation of the insulating plate can prevent current from being transmitted to the mounting box, and the installation of the insulating rod can prevent current from being transmitted to the connecting block, thus preventing current from flowing onto the surface of the mounting box and avoiding electric shock.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-5In this utility model, an automotive interior touch dome light includes a mounting box 1. The mounting box 1 has a connecting mechanism 2 inside. The connecting mechanism 2 includes two first bearings 201. The inner rings of the two first bearings 201 are fixedly connected to a threaded rod 202. A first gear 203 is fixedly connected to the outer surface of the threaded rod 202. A threaded cylinder 204 is threadedly connected to the outer surface of the threaded rod 202. A connecting block 205 is fixedly connected to the outer surface of the threaded cylinder 204. An isolation rod 206 is fixedly connected to the outer surface of the connecting block 205. The isolation rod 206 can block current, preventing it from being transmitted to the mounting box 1, and can also control the position of the adjusting component 403. The first gear 203 can drive the threaded rod 202 to rotate, and the threaded rod 202 can drive the threaded cylinder 204 to move horizontally, facilitating the adjustment of the position of the isolation rod 206 by the operator.
[0026] The outer surface of the mounting box 1 is provided with a control mechanism 3. The control mechanism 3 includes a second bearing 301. A rotating rod 302 is fixedly connected to the inner ring of the second bearing 301. A knob 303 is fixedly connected to one end of the rotating rod 302, and a second gear 304 is fixedly connected to the other end of the rotating rod 302. The outer surface of the second gear 304 meshes with the outer surface of the first gear 203. The knob 303 can drive the rotating rod 302 to rotate, and the rotating rod 302 can drive the second gear 304 to rotate, which makes it convenient for the staff to adjust the resistance.
[0027] An adjustment mechanism 4 is fixedly connected to the outer surface of the mounting box 1. The adjustment mechanism 4 includes two insulating plates 401. A resistor rod 402 is fixedly installed on one side of the two insulating plates 401 that are close to each other. An adjustment component 403 is slidably connected to the outer surface of the resistor rod 402. The adjustment component 403 allows the staff to easily control the resistance of the resistor rod 402. A lighting lamp 5 is provided on the outer surface of the mounting box 1. A wire hole 6 is provided on the outer surface of the mounting box 1. The wire hole 6 allows the staff to easily connect the wire to the resistor rod 402 in series.
[0028] The working principle of this utility model is as follows:
[0029] In use, firstly, the wire is connected in series to the resistor rod 402 through the wire hole 6. Then, the mounting box 1 is fixedly installed in a suitable position. When the brightness of the lamp needs to be adjusted, the knob 303 is turned. When the knob 303 is turned, it will drive the rotating rod 302 to rotate. When the rotating rod 302 rotates, it will drive the second gear 304 to rotate. The second gear 304 will drive the first gear 203 to rotate. When the first gear 203 rotates, it will drive the threaded rod 202 to rotate. When the threaded rod 202 rotates, it will drive the threaded cylinder 204 to move horizontally, thereby driving the connecting block 205, the insulating rod 206, and the adjusting component 403 to move horizontally. When the adjusting component 403 slides horizontally on the resistor rod 402, the resistance of the resistor rod 402 can be changed, thereby adjusting the resistance of the lighting lamp 5 and ultimately adjusting the brightness of the lighting lamp 5.
