By arranging the plurality of scale marks 13, the sliding distance of the sliding sleeve 2 relative to the sliding rod 1 can be accurately recorded, and the sensor mounting rack 200 of other lamps 100 can be adjusted according to the recorded sliding distance, so that the adjustment efficiency of the sensor mounting rack 200 is improved.

In some embodiments, as shown in fig. 7 and 13, fig. 13 is a schematic structural view of the universal joint 6 in some embodiments of the present application. The sensor mounting frame 200 further comprises a universal joint 6, the universal joint 6 comprises a first joint 61 and a second joint 62, the first joint 61 is fixedly connected with the sliding sleeve 2, the second joint 62 is movably connected with the first joint 61, and the second joint 62 is configured to be fixedly connected with the sensor 300.

By providing the universal joint 6, the flexibility of adjusting the position of the sensor 300 by the sensor mounting bracket 200 can be improved, so as to ensure that the sensor 300 is in an optimal position relative to the lamp 100, and therefore, the sensor 300 can accurately sense the existence of a person.

As shown in fig. 14, fig. 14 is a schematic diagram of the sensor mount 200 adjusting the position of the sensor 300 through the universal joint 6 according to some embodiments of the present application. As can be seen from the figure, the tilt angle of the detection surface of the sensor 300 relative to the light emitting surface of the lamp 100 can be changed by swinging and adjusting the second joint 62 in the universal joint 6 relative to the first joint 61, so that the detection surface of the sensor 300 is at the optimal tilt angle relative to the ground, thereby ensuring that the sensor 300 can accurately detect people on the ground.

Referring to fig. 15, fig. 15 is a schematic view of sensor mount 200 adjusting the position of sensor 300 via gimbal 6 according to other embodiments of the present invention. As can be seen from the figure, by the swinging adjustment of the second joint 62 relative to the first joint 61 in the universal joint 6, the position of the sensor 300 relative to the lamp 100 in a plane parallel to the light exit surface of the lamp 100 can be adjusted, so as to ensure that the sensor 300 can accurately detect people on the ground.

In some embodiments, as shown in fig. 7 and 13, the universal joint 6 is a ball-end universal joint 6, the first joint 61 includes a ball end groove 611, and the second joint 62 includes a ball end 621 that mates with the ball end groove 611. The universal joint 6 further comprises a stop member 63, a threaded through hole 612 is formed in a groove wall of the ball groove 611, and the stop member 63 is matched with the threaded through hole 612 and can abut against the ball 621.

During adjustment, when the position is adjusted to the optimal position, the stop 63 is rotated to make the stop 63 abut against the ball 621, so as to prevent the ball 621 from moving relative to the ball groove 611, and further lock the position of the sensor 300.

Through setting the universal joint 6 to the above structure, not only the structure of the universal joint 6 is simpler, the dismounting of the universal joint 6 is facilitated, but also the relative movement between the first joint 61 and the second joint 62 can be locked through the stop piece 63, the change of the installation angle of the sensor 300 caused by the rotation of the second joint 62 relative to the first joint 61 is avoided, and the sensor 300 can be more accurately used for detecting people or objects.

The stop 63 may be a screw or a bolt, and is not limited herein.

In some embodiments, as shown in fig. 13, a plurality of concave points 622 are distributed on the surface of the ball head 621 for the stop 63 to insert into. When the stop 63 is inserted into the concave point 622, the ball 621 is better prevented from moving relative to the ball groove 611, so that the sensor 300 can be better locked in a certain position.

In some embodiments, as shown in fig. 7 and 13, the first connector 61 further comprises a threading hole 613 communicating with the ball groove 611, and the second connector 62 further comprises a threading cavity 623 communicating with the threading hole 613, wherein the threading hole 613 and the threading cavity 623 are configured to pass through a power supply line of the sensor 300.

Thus, the power supply wires of the sensor 300 can pass through the wire holes and the threading cavity 623, that is, pass through the inside of the universal joint 6 to be connected with the driver 122, so that the power supply wires of the sensor 300 do not need to be exposed outside the universal joint 6, and not only can the power supply wires of the sensor 300 be protected, but also the appearance of the lamp 100 is tidier.

As shown in fig. 7, the sensor 300 is screwed into the second connector 62, specifically, an internal thread is provided on the wall of the threading cavity 623 of the second connector 62, and the threaded post on the sensor 300 extends into the threading cavity 623 to match the internal thread.

Of course, the sensor 300 can also be fixedly connected to the second connector 62 by clipping, plugging, etc.

In fig. 7, the installation positions of the sliding rod 1 and the sliding sleeve 2 can also be exchanged, that is: the sliding rod 1 is connected with the sensor 300, the sliding sleeve 2 is connected with the driving box 121, at this time, the fixing part is the sliding sleeve 2, and the adjusting part is the sliding rod 1, so that the position adjustment of the sensor 300 relative to the lamp 100 can also be realized.

In the embodiment of the application, the telescopic structure of the adjusting part relative to the fixing part is not limited to the structure of the sliding sleeve 2 matched with the sliding rod 1, and other structures can be adopted, for example, the fixing part and the adjusting part are both plate-shaped structures, and the adjusting part is connected with the fixing frame in a sliding manner, so that the adjusting part can stretch relative to the fixing part. For example, the adjusting member may be slidably connected to the fixing frame via a sliding rail.

A plurality of stoppers 3 are provided on the adjuster, and a lock 4 is provided on the fixing member. However, the position of the stopper 3 and the position of the locking member 4 may be reversed, that is: the plurality of stopper portions 3 are provided on the mount, and the lock portion 42 is provided on the adjuster.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
