Description

Technical Field

[0001] This utility model relates to the field of lighting control module technology, specifically a lighting controller with an annular sealing structure. Background Technology

[0002] In modern lighting systems, the lighting control module is a core control component. Its working environment is often complex and diverse, and it may be affected by various adverse factors such as dust, water vapor, and humidity. Once water vapor or dust enters the control module, it will not only affect the normal operation of electronic components, causing control signal disorder and lighting adjustment failure, but also cause short circuits and component damage in severe cases, greatly shortening the service life of the control module and increasing maintenance costs and safety hazards.

[0003] Currently, the sealing structure design of common lighting control modules on the market has certain limitations. Most control modules adopt traditional planar sealing or simple rubber ring sealing methods, and achieve sealing by tightening the bolts between the top cover and the base. However, this sealing method mainly relies on external pressure to make the sealing element fit with the mating surface. The sealing pressure distribution is uneven, and it is easy for the sealing to be poor at the corners or joints. Especially during long-term use, as the bolts loosen and the sealing element ages, the sealing performance will gradually decline, making it difficult to maintain a good sealing effect.

[0004] Furthermore, traditional sealing structures are mostly integral designs. When local wear or aging occurs, the entire seal needs to be replaced, making maintenance cumbersome. At the same time, for some lighting control modules that require frequent operation or are installed outdoors or in humid environments, the requirements for sealing performance are even higher. Traditional sealing structures can hardly meet the needs of their long-term stable operation. Therefore, developing a sealing structure for lighting control modules with more reliable sealing performance and the ability to adapt to complex environments has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to provide a light controller with an annular sealing structure to solve the problems mentioned in the background art. Traditional sealing methods rely on external pressure, resulting in uneven pressure distribution, poor sealing at corners or joints, and decreased sealing performance due to loose bolts and aging of seals after long-term use. Furthermore, traditional sealing structures are integral designs, requiring replacement of the entire structure when there is local wear or aging, making maintenance cumbersome and unable to meet the high sealing performance requirements in complex environments such as outdoor and humid conditions.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a light controller with an annular sealing structure, including a base, an upper cover being snapped onto the upper end of the base, and the upper cover being fixedly installed with the base by locking bolts, a touch screen being provided on the upper surface of the base, and a control module being installed inside the base, and a sealing mechanism being provided inside the upper cover, achieving the purpose of sealing from the inside by annular splicing sealing, thus ensuring the overall sealing performance;

[0007] The sealing mechanism includes: a flap, which is rotatably mounted on the upper inner surface of the base, and a contact rod is fixedly connected to the end of the flap facing the outside of the base, and a sealing block is fixedly connected to the end of the flap facing the inside of the base; a rotating adjusting ring is installed on the upper inner surface of the base, and a pressing block is fixedly provided on the lower surface of the adjusting ring, and a linkage tooth block is fixedly provided on the upper surface of the adjusting ring; a switching motor is fixedly installed on the upper outer surface of the base, and a switching gear is fixedly connected to one end of the output shaft of the switching motor.

[0008] A sealing groove is provided on the outer surface of one end of the sealing block, and a sealing protrusion is fixedly provided on the outer surface of the other end of the sealing block.

[0009] Preferably, the sealing block has an arc-shaped design and an L-shaped cross-section, and the outer surface of the sealing block is in contact with the inner surface of the connection between the base and the top cover.

[0010] By adopting the above technical solution, the arc-shaped design allows multiple sealing blocks to be spliced ​​into a ring, achieving a ring seal at the connection between the base and the top cover. The L-shaped cross-section design increases the contact area between the sealing blocks and the inner surface of the connection between the base and the top cover, further improving the tightness of the seal and ensuring a more reliable sealing effect.

[0011] Preferably, the sealing groove is a semi-circular arc design, the sealing protrusion is a semi-circular protrusion, and the outer diameter of the sealing protrusion is the same as the inner diameter of the sealing groove.

[0012] By adopting the above technical solution, when multiple sealing blocks are spliced ​​together, the sealing protrusions can be precisely embedded in the sealing grooves to form a complementary sealing structure. This design not only enhances the tightness of the connection between adjacent sealing blocks, but also effectively prevents moisture, dust and other particles from entering the control module from the splicing gaps, further improving the overall sealing performance.

[0013] Preferably, the extrusion blocks and contact rods are arranged in a one-to-one correspondence, and the extrusion blocks are distributed at equal angles on the lower surface of the adjusting ring.

[0014] By adopting the above technical solution, it can be ensured that when the adjusting ring rotates, each extrusion block can accurately apply extrusion force to the corresponding contact rod, so that each flap drives the sealing block to move synchronously to the inner surface of the connection between the base and the top cover, ensuring that the sealing block is subjected to uniform force and improving the consistency of the seal.

[0015] Preferably, the extrusion block is designed as a right-angled trapezoid, and the extrusion block is in contact with the contact rod through an inclined surface.

[0016] By adopting the above technical solution, when the adjusting ring rotates, the inclined surface of the extrusion block can smoothly extrude the contact rod, converting the rotational motion of the adjusting ring into the linear extrusion motion of the contact rod. This allows the flap to slowly and stably adhere the sealing block to the inner surface of the connection between the base and the top cover, avoiding damage to the components due to excessive force and ensuring the stability of the sealing and pressurizing process.

[0017] Preferably, one end of the switching gear penetrates the upper inner surface of the base, and the switching gear is engaged with the adjusting ring through a linkage tooth block.

[0018] By adopting the above technical solution, the power of the switching motor can be transmitted to the adjusting ring through the meshing of the switching gear and the linkage gear block, thereby driving the adjusting ring to rotate stably, providing a power basis for the extrusion block to extrude the contact rod, realizing the automated operation of the sealing mechanism, and ensuring the precision and controllability of the sealing process.

[0019] Compared with the prior art, the beneficial effects of this utility model are: the lighting controller with an annular sealing structure:

[0020] 1. A ring-shaped splicing sealing method composed of sealing blocks is adopted. The seal is achieved by internal pressure. The sealing protrusion at one end of the sealing block precisely matches the sealing groove of the adjacent sealing block. With the help of the flap, the sealing blocks are pressurized. Compared with the traditional sealing method that relies on external pressure, the sealing pressure distribution is more uniform. It effectively avoids the situation of poor sealing at the corners or splices, greatly improving the overall sealing performance. It can better prevent dust, water vapor and other substances from entering the base and the inside of the top cover, ensuring the normal operation of the control module and electronic components in the base. It reduces the occurrence of control signal disorder, light adjustment failure, circuit short circuit and component damage caused by sealing problems, and extends the service life of the control module.

[0021] 2. The sealing mechanism achieves internal pressure sealing through the cooperation of components such as adjusting ring, squeezing block, and flap. When the adjusting ring rotates, the squeezing block squeezes the contact rod, causing the flap to drive the sealing block to tightly adhere to the inner surface of the connection between the base and the top cover. This structural design makes the sealing pressure less susceptible to external factors. Even with long-term use, it can reduce the problem of decreased sealing performance caused by loose locking bolts or aging of sealing components, similar to traditional seals. It ensures the continuity and stability of the sealing effect and is more adaptable to complex environments with high sealing performance requirements, such as outdoor and humid environments.

[0022] 3. The sealing block has an arc-shaped design and is spliced ​​with sealing grooves and sealing protrusions. It is a modular ring splicing structure. When the local sealing block is worn or aged, there is no need to replace the entire sealing component. Just remove the locking bolts, open the top cover, and replace the damaged sealing block. This reduces maintenance costs and difficulty and solves the problem of cumbersome maintenance of traditional integral sealing structures.

[0023] 4. By switching the motor to drive the switching gear, the linkage gear block and the adjusting ring are driven to rotate. The extrusion block on the adjusting ring presses the contact rod to make the flap rotate, thereby realizing the sealing action of the sealing block. The entire sealing process is automatically controlled by the motor, with a high degree of automation, convenient operation, and precise coordination of each component, which can quickly realize the switching of the sealing state and ensure the high efficiency of the sealing operation.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0033] Please see Figures 1-7 This utility model provides a technical solution: a light controller with an annular sealing structure.

[0034] Example 1: This example discloses: a base 1, a top cover 2 that is snapped onto the upper end of the base 1, and the top cover 2 and the base 1 are fixedly installed by locking bolts 3. A touch screen 4 is provided on the upper surface of the base 1, and a control module 5 is installed inside the base 1. A sealing mechanism is provided inside the top cover 2. The sealing mechanism is achieved by applying pressure from the inside through a ring splicing sealing method, so as to ensure the overall sealing performance.

[0035] The sealing mechanism includes: a flap 6, which is rotatably mounted on the upper inner surface of the base 1, and a contact rod 7 is fixedly connected to the end of the flap 6 facing the outside of the base 1, and a sealing block 8 is fixedly connected to the end of the flap 6 facing the inside of the base 1. A rotating adjusting ring 11 is installed on the upper inner surface of the base 1, and a pressing block 12 is fixedly provided on the lower surface of the adjusting ring 11. A linkage tooth block 13 is fixedly provided on the upper surface of the adjusting ring 11. A switching motor 14 is fixedly installed on the upper outer surface of the base 1, and a switching gear 15 is fixedly connected to one end of the output shaft of the switching motor 14.

[0036] The extrusion blocks 12 and the contact rods 7 are arranged in a one-to-one correspondence, and the extrusion blocks 12 are distributed at equal angles on the lower surface of the adjusting ring 11;

[0037] The extrusion block 12 is designed as a right-angled trapezoid, and the extrusion block 12 is in contact with the contact rod 7 through the inclined surface;

[0038] One end of the switching gear 15 penetrates the upper inner surface of the base 1, and the switching gear 15 is connected to the adjusting ring 11 through the linkage tooth block 13.

[0039] When sealing is required, the switching motor 14 starts, and its output shaft drives the switching gear 15 to rotate. Since the switching gear 15 is meshed with the linkage tooth block 13 on the adjusting ring 11, the rotation of the switching gear 15 will drive the adjusting ring 11 to rotate on the upper inner surface of the base 1. When the adjusting ring 11 rotates, the pressing block 12 fixedly set on its lower surface also rotates. Because the pressing block 12 is a right trapezoidal design and fits against the contact rod 7 through the inclined surface, and the pressing block 12 and the contact rod 7 correspond one-to-one and are distributed at equal angles, the inclined surface of the pressing block 12 will squeeze the contact rod 7. When the contact rod 7 is compressed, it will cause the flap 6, which is fixedly connected to it, to rotate on the inner surface of the upper end of the base 1. When the flap 6 rotates, the sealing block 8, which is fixedly connected to the end facing the inside of the base 1, will move to the inner surface of the connection between the base 1 and the upper cover 2 and fit tightly. By applying pressure from the inside, the sealing mechanism of the ring splicing is used to achieve a seal, ensuring the sealing between the base 1 and the upper cover 2. The locking bolt 3 further strengthens the connection between the base 1 and the upper cover 2. The touch screen 4 is used for operation control, and the control module 5 is responsible for overall control and coordination.

[0040] Example 2: This example is based on Example 1: a sealing groove 9 is provided on the outer surface of one end of the sealing block 8, and a sealing protrusion 10 is fixedly provided on the outer surface of the other end of the sealing block 8.

[0041] The sealing block 8 has an arc-shaped design and an L-shaped cross-section. The outer surface of the sealing block 8 is in contact with the inner surface of the connection between the base 1 and the top cover 2.

[0042] The sealing groove 9 has a semi-circular arc design, and the sealing protrusion 10 has a semi-circular protrusion, with the outer diameter of the sealing protrusion 10 being the same as the inner diameter of the sealing groove 9.

[0043] The structural design of the sealing block 8 further enhances the sealing effect. The sealing block 8 has an arc-shaped design and an L-shaped cross-section. Its outer surface is in contact with the inner surface of the connection between the base 1 and the upper cover 2. When the sealing mechanism is working, under the combined action of the switching motor 14, switching gear 15, adjusting ring 11, pressing block 12, contact rod 7, and flap 6, the sealing block 8 is pressed against the inner surface of the connection between the base 1 and the upper cover 2. At this time, among adjacent sealing blocks 8, the sealing protrusion 10 of one sealing block 8 will embed into the sealing protrusion of the other sealing block 8. Inside the groove 9, since the sealing protrusion 10 is a semi-circular protrusion and its outer diameter is the same as the inner diameter of the semi-circular arc-shaped sealing groove 9, the two can fit together precisely, so that multiple arc-shaped sealing blocks 8 form a complete annular sealing structure. This structure not only achieves basic sealing through internal pressure, but also further improves the tightness of the annular seal through the fitting of the sealing protrusion 10 and the sealing groove 9, effectively preventing external dust, water vapor and other substances from entering the interior of the base 1 and the top cover 2, ensuring the normal operation of the control module 5, while the touch screen 4 can be operated and controlled normally.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
