Description

Technical Field

[0001] The utility model relates to the technical field of sensors, and specifically, to a ceiling-mounted presence sensor. Background Art

[0002] Ceiling sensors, as the name implies, are sensors installed on the top of a room (such as the ceiling). According to their induction principles and technical characteristics, they can be mainly divided into several types such as infrared human body sensors, radar sensors, and optical sensors. Among them, infrared human body sensors and radar sensors are most widely used in the fields of smart home and security.

[0003] There are some drawbacks in the use of existing devices. For example, existing ceiling sensors are generally fixed by screws, and maintenance personnel need to use special tools to open the device to access the internal sensors or other key components. The inability to quickly open the sensor makes it time-consuming every time to clean, repair, or replace internal components such as the sensor, resulting in low maintenance efficiency. Moreover, if only relying on simple fixing methods (such as screws or buckles), the connection between the shells may not be firm enough, and it is easy to loosen or even fall off, affecting the overall structure and functional stability of the device. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a ceiling-mounted presence sensor to solve the problem that it is time-consuming every time to clean, repair, or replace internal components such as the sensor due to the inability to quickly open the sensor, resulting in low maintenance efficiency.

Specific implementation manner

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Embodiment 1

[0019] As Figure 1 、 Figure 2 and Figure 3 shown, the present invention provides a technical solution: a ceiling-mounted presence sensor, including a bottom shell 10, an auxiliary shell 11 and an upper shell 12. A perforation 13 is provided at the center of the bottom shell 10. A sensor protection shell 14 adapted to the perforation 13 is fixed at the center of the auxiliary shell 11. The auxiliary shell 11 is fixedly installed on the upper end surface of the bottom shell 10. The upper shell 12 is arranged on the upper end surface of the auxiliary shell 11. A sensor body 15 is arranged on the inner top wall of the upper shell 12. A plurality of lower mounting cylinders 16 are fixedly installed on the upper end surface of the auxiliary shell 11. A first mounting component is arranged inside the lower mounting cylinder 16. A plurality of upper mounting cylinders 17 are fixedly installed on the inner top wall of the upper shell 12. The tops of the plurality of upper mounting cylinders 17 penetrate through the upper shell 12. A second mounting component is arranged inside the upper mounting cylinder 17. The first mounting component and the second mounting component are used in cooperation. In the specific use process, the ceiling-mounted presence sensor forms an integral outer shell through the combination of the bottom shell 10, the auxiliary shell 11 and the upper shell 12. The auxiliary shell 11 is fixed to the bottom shell 10 by bolts, and the upper shell 12 is detachably fixed to the auxiliary shell 11 through the cooperation of the first mounting component and the second mounting component. The detachable upper shell 12 design enables users or maintenance personnel to easily access the inside of the sensor for necessary cleaning, repair or replacement work. The sensor protection shell 14 is used to protect the sensor body 15 from external physical damage, such as dust, moisture, etc., and the sensor protection shell 14 is made of a transparent material, and light can pass through. After the sensor is installed at a specified position (such as the ceiling), the sensor body 15 starts to work, responsible for detecting changes in the surrounding environment (such as human movement, light changes, etc.), and converting the signal into an electrical signal for processing, so as to judge whether there is an object (such as a person) in the sensing area. Once an object is detected, the sensor will output a corresponding electrical signal, and this signal can be received and processed by the connected control system, thereby triggering corresponding actions (such as turning on the light, alarming, etc.).

[0020] As an implementation manner in this embodiment, asFigure 2 , Figure 3 and Figure 4 As shown in Figure 2 , Figure 3 and Figure 4 , the first mounting component includes a threaded post 20 threadedly fixed inside the lower mounting cylinder 16. The top end of the threaded post 20 is fixedly connected to a first disc 21. A first mounting plate 22 and a first arc-shaped plate 23 are fixedly connected to the outer wall of the first disc 21. A first mounting opening 24 is formed at the top of the first mounting plate 22. One end of the first arc-shaped plate 23 is fixedly connected to the side wall of the first mounting plate 22. The second mounting component includes a top cover 30 threadedly fixed to the top end of the upper mounting cylinder 17. A knob 36 is fixedly installed on the upper end surface of the top cover 30, which is convenient for the user to grasp and rotate. The lower end surface of the top cover 30 is fixedly connected to a connecting rod 31. The bottom end of the connecting rod 31 passes through the upper mounting cylinder 17 and its end is fixedly connected to a second disc 32. A second mounting plate 33 and a second arc-shaped plate 34 are fixedly connected to the outer wall of the second disc 32. A second mounting opening 35 is formed at the bottom of the second mounting plate 33. One end of the second arc-shaped plate 34 is fixedly connected to the side wall of the second mounting plate 33. In the specific use process, first, the upper shell 12 is snap-fitted onto the bottom shell 10, and then the upper shell 12 and the bottom shell 10 are further fixed by the first mounting member and the second mounting member. It should be noted that the auxiliary shell 11 is fixed to the bottom shell 10. Therefore, the fixation of the upper shell 12 and the auxiliary shell 11 can further fix the bottom shell 10. When the upper shell 12 is snap-fitted to the bottom shell 10, the second disc 32 is located directly above the first disc 21. Then, the top cover 30 is manually rotated to drive the connecting rod 31 to rotate. The connecting rod 31 drives the second disc 32 to rotate, so that the second mounting plate 33 and the second arc-shaped plate 34 on the second disc 32 rotate synchronously. The second mounting opening 35 on the second mounting plate 33 is inserted into the first arc-shaped plate 23, and the second arc-shaped plate 34 is inserted into the second mounting opening 35 on the first mounting plate 22, so that the upper shell 12 is firmly fixed to the auxiliary shell 11. And this design can easily open the outer shell for internal inspection or maintenance without special instruments, so that ordinary users or maintenance personnel can easily operate.

[0021] As an implementation manner in this embodiment, as Figure 1 shown, two heat dissipation openings 121 are formed on the upper end surface of the upper shell 12. The heat dissipation openings 121 can exchange the hot air inside the device with the cooler air outside, thereby taking away the heat and reducing the temperature inside the device.

[0022] As an implementation manner in this embodiment, as Figure 3 shown, the sensor protection shell 14 protrudes outward from the auxiliary shell 11. The sensor protection shell 14 is inserted into the through hole 13. The sensor protection shell 14 passing through the through hole 13 can prevent the sensor from being blocked by the bottom shell 10 during the detection process.

[0023] Working principle: First, fix the auxiliary shell 11 to the bottom shell 10 with bolts, then snap the upper shell 12 onto the bottom shell 10, and further reinforce the fixation of the upper shell 12 and the bottom shell 10 through the first mounting member and the second mounting member. It should be noted that since the auxiliary shell 11 is fixed to the bottom shell 10, the fixation of the upper shell 12 and the auxiliary shell 11 can achieve the effect of further fixing the bottom shell 10. When the upper shell 12 is snapped onto the bottom shell 10, the second disc 32 is directly above the first disc 21. Then, manually rotate the top cover 30 to drive the connecting rod 31 to rotate. The connecting rod 31 drives the second disc 32 to rotate, so that the second mounting plate 33 and the second arc plate 34 on the second disc 32 rotate synchronously. The second mounting opening 35 on the second mounting plate 33 is inserted into the first arc plate 23, and the second arc plate 34 is inserted into the second mounting opening 35 on the first mounting plate 22, thereby firmly fixing the upper shell 12 to the auxiliary shell 11.

[0024] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
