[0046] Specifically, the arc-shaped swing limiting structure includes an arc-shaped limiting groove 14 arranged at the bottom of the bottom shell 1 , and a bearing 321 located in the arc-shaped limiting groove 14 is provided at the lower end of the driving rod 32 .

[0050] An annular inner ring 4 is provided on the inner wall of the bottom shell 1. Specifically, an inner annular positioning groove is provided on the inner wall of the bottom shell 1. The annular inner ring 4 is placed in the inner annular positioning groove. In order to facilitate assembly, the bottom shell 1 of this embodiment includes two symmetrically arranged half bodies 11, and the two ends of the two half bodies 11 are connected by a plurality of concave-convex matching connection mechanisms.

[0051] The concave-convex fitting connection mechanism comprises ball head insert rods 12 arranged at both ends of any half body 11, and conical expansion sleeves 13 for inserting the ball head insert rods 12 are respectively arranged at both ends of the other half body 11.

[0052] That is, the butt connection is achieved through the cooperation between the conical expansion sleeve 13 and the ball head plug rod 12, the assembly is simple and convenient, and the production efficiency is virtually improved.

[0053] An annular space is provided between the annular inner ring 4 and the bottom of the inner annular positioning groove. The design of the annular space can improve the heat dissipation performance.

[0054] Specifically, the annular inner ring 4 of this embodiment is made of elastic plastic. A plurality of circumferentially distributed decompression grooves 41 are provided at one end of the annular inner ring 4 close to the opening of the bottom shell 1, and an elastic deformation block 1 is formed between two adjacent decompression grooves 41.

[0055] An inner convex mating portion 42 is provided on the inner wall of one end of the annular inner ring 4 provided with a pressure relief groove 1 41. The designed inner convex mating portion 42 can improve the mating strength after subsequent assembly. An annular cylinder 21 that can be inserted into the annular inner ring 4 is provided at one end of the upper cover 2 close to the bottom shell 1, and a plurality of circumferentially distributed pressure relief grooves 2 22 are provided at one end of the annular cylinder 21 away from the upper cover 2, and an elastic deformation block 2 is formed between two adjacent pressure relief grooves 22.

[0056] The number of the second decompression grooves 22 is less than the number of the first decompression grooves 41 .

[0057] An annular matching groove 23 for the inner convex matching portion 42 to be inserted into is provided on the outer wall of the annular cylinder 21, and an axial locking structure is provided between the annular inner ring 4 and the annular cylinder 21.

[0058] The elastic action of the spring 44 forces the ball 43 to always be partially stuck in the arc groove 46, thus achieving axial connection.

[0059] An annular heat dissipation mechanism 5 is provided in the bottom shell 1. Specifically, the annular heat dissipation mechanism 5 of this embodiment includes an upper heat dissipation ring 51 provided in the bottom shell 1, a lower heat dissipation ring 52 located below the upper heat dissipation ring 51 is provided at the bottom of the bottom shell 1, and the upper heat dissipation ring 51 and the lower heat dissipation ring 52 are connected by a plurality of circumferentially distributed connecting rods 53.

[0060] See also Figure 2 , shown is a principle block diagram of a multifunctional timing switch according to another embodiment of the present invention. A human body sensing module is also arranged in the bottom shell 1. The human body sensing module is connected to the control module through a functional interface for sensing human body movement and outputting a second control signal.

[0061] In the above technical scheme, when the switch configures the clock module to turn on the timing clock, and the configuration function interface is not connected to the sensor module, the switch is configured as a timing switch, and the control module controls the switch module according to the first control signal; similarly, in actual use, when the switch configures the clock module to turn off the timing clock, and the configuration function interface is connected to the sensor module, the switch is configured as an induction switch, which is similar to the induction switch function commonly used in the prior art, and the control module controls the switch module according to the second control signal; the sensor module adopts a human body sensing module, which is a human body sensing switch in the prior art.

[0062] Similarly, in some applications, it is necessary to use a timing switch and an induction switch simultaneously. In this case, the control module needs to receive the first control signal and the second control signal at the same time to control the switch module. In public lighting in some occasions, such as corridor lighting, there is sufficient light during the day and there is no need to turn on the lighting facilities. When the light is insufficient at night, induction control is used to achieve on-demand lighting. In the prior art, induction control is usually used, or lighting is directly turned on in a normally open manner, which causes energy waste to a certain extent. The multifunctional timing switch of the present invention can perfectly solve the above technical problems. Since the timing control induction can be set to turn on, for example, the timing is set from 18:00 to 6:00 a.m. every day, the induction control switch module is turned on during the timing period, that is, the lighting facilities are started by human body induction in a night environment with insufficient light, and the lighting facilities are not started at other times.

[0063] It can be seen from this that the multifunctional timer switch of the present invention can be configured with different functions according to actual use requirements, so that it can be applied in different occasions.

[0064] In another use requirement, when the prior art lamp is used at night, the user needs to touch the switch to turn on the lighting, which makes it inconvenient for the user to use it at night. Figure 3, shown is a principle block diagram of the multifunctional timing switch of the present invention in a practical application, the panel switch is connected with the multifunctional timing switch and the LED lamp, and is used to connect the LED lamp to the AC mains or connect the multifunctional timing switch by pressing the switch; the multifunctional timing switch is connected with the AC mains, and is used to set the timing clock and start the human body sensing control within the timing clock. When the human body is sensed, the switch module connects the AC mains, otherwise, the switch module disconnects the AC mains connection. In the above application, the multifunctional timing switch of the present invention is used together with the traditional panel switch. During normal use (non-timing period), the panel switch is used to control the opening and disconnection of the LED lamp. When the panel switch disconnects the LED lamp from the AC mains, the panel switch connects the LED lamp and the multifunctional timing switch to make the two electrically connected, and the LED lamp is controlled by the multifunctional timing switch. By setting the timing time, the lighting is lit in a human body sensing manner in a night environment, while the lighting is still controlled by the normal switch at other times. For example, the timing time is set to 0:00 to 6:00 in the morning of each day, and the sensing control switch module is turned on during the timing period, so as to facilitate the user's night use.

[0065] In the above technical solution, both the panel switch and the LED lamp can adopt the general modules of the existing technology. Therefore, there is no need to change the existing lighting circuit. At the same time, the panel switch and the multi-function timing switch can be set as one, and only one 86-wire box is required. In actual applications, it is only necessary to replace the traditional panel switch with the multi-function timing switch of the present invention to upgrade to smart lighting.
