Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments:

with reference to fig. 1 to 3, the utility model provides an adjustable reading lamp of illumination angle, its use scene can be but not limited to install in on-vehicle indoor, and it includes body 1, upper cover 2 and lamp shade 3. Wherein the upper cover 2 is fixedly connected with the body 1, and the upper cover 2 is fixed with other supporting parts or fixing parts outside, such as a ceiling, a ceiling in a vehicle cavity, etc. The body 1 is connected with the lampshade 3. The connection of upper cover 2, body 1 and lamp shade 3 forms an accommodation cavity. Corresponding control circuit and light source are installed in the accommodating cavity, and the light source is naturally connected with the control circuit to play a role in controlling related circuits. Because the utility model discloses the key improvement lies in how to realize the angle modulation of reading lamp, and the circuit aspect is not improved, directly adopt prior art can, and do not influence the utility model discloses an implementation of structure, consequently do not give unnecessary details.

Specifically, in order to realize the illumination angle of reading lamp adjustable, the utility model discloses 2 in the upper cover in-connection have to the angle rocking arm 4 that lamp shade 3 extends, 4 one ends of angle rocking arm are connected with

upper cover

2, and 2 one ends (the other end) that the upper cover was kept away from to this angle rocking arm 4 are connected with spacing arm 5, are equipped with rotation axis 6 on the body 1, the one end of lamp shade 3 is equipped with two connecting pieces 7, and the extending direction of connecting piece 7 sets up towards body 1. Two connecting piece 7 is connected on rotation axis 6 to connecting piece 7 can rotate around rotation axis 6, thereby realizes that lamp shade 3 can rotate, lays the foundation for angular adjustment.

Further, a return spring 8 is sleeved on the rotating shaft 6, and the return spring 8 is located between the two connecting pieces 7. The return spring 8 provides a restoring force for returning the lamp housing 3 after the subsequent lamp housing 3 rotates by a certain angle.

The other end of the lampshade 3 is provided with a mounting hole, an adjusting button 9 is mounted on the mounting hole, and the adjusting button 9 is used for a user to press to output external force to adjust the angle of the lampshade 3. Adjusting button 9 is equipped with stopper 10 on the terminal surface of upper cover, a side surface of stopper 10 is equipped with the closed regulation route 11 that supplies spacing arm 5 to stretch into, adjusting button 9 is used for making the stopper produce the single displacement in vertical direction under single exogenic action to change spacing arm 5 in the position of closed regulation route 11, thereby make connecting piece 7 relative rotation axis 6 produce turned angle. That is, the limiting block 10 moves upwards under the action of external force, and the position of the limiting arm 5 clamped on the closed adjusting path 11 is correspondingly changed, the limiting arm 5 limits the movement of the limiting block 10 under the action of no external force, so that the angle can be changed and adjusted after the external force is applied, and the angle is kept until the angle is adjusted by the external force again.

As the utility model discloses preferred embodiment forms two at least setpoint on the closed regulation route 11 to when stopper 10 produced the single displacement, spacing arm 5 removed to the setpoint and corresponds the position. Two said positioning points mean that the illumination angle can be adjusted by two steps, even if two angles are adjusted, if three positioning points, three angle adjustments are meant.

Schematic diagram of the closed adjustment path 11 referring to fig. 4, it is shown that three positioning points, i.e. three positions a, b, c, are formed on the closed adjustment path 11. The position a is the original position, that is, the lampshade 3 does not rotate relative to the body, and under the conventional arrangement, the lampshade 3 is horizontally arranged relatively. When the user applies an external force through the adjusting button 9, the limiting block 10 is moved upward by the external force, so that the limiting arm is originally at the a position, the position of the limiting block 10 is changed, the position of the limiting arm 5 clamped on the closed adjusting path 11 is changed accordingly, and the limiting block 10 moves upward, which corresponds to the position of the limiting arm 5 on the closed adjusting path 11 moving downward, the closed adjusting path 11 is a smooth closed curve, as shown in fig. 4, the positioning point b and the positioning point c arranged at the lower part are points on the adjacent curves, which are located at upper positions, i.e. form a peak, and the positioning point b and the positioning point c are located at peak positions, so that for example, after the user provides the external force, the limiting arm 5 is changed from the a position to the b position, and at this time, the connecting member 7 necessarily rotates relative to the rotating shaft 6 due to one end moving upward, i.e. the entire lamp shade 3 is angularly varied. And then from anchor point b to anchor point c.

As a modified embodiment, the light-transmitting cover 31 is provided on the lamp housing 3, and the position of the light-transmitting cover 31 is particularly preferably set in the middle of the lamp housing 3. The angle rocker arm 4 and the limit arm 5 form an L shape.

The connecting piece 7 comprises a connecting plate, one end of the connecting plate is provided with a connecting hole, one side of the connecting plate, which is close to the upper cover 2, is provided with a notch, the notch is communicated with the connecting hole and the outside, and the connecting hole is sleeved on the outer ring of the rotating shaft.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
