[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0022] Please refer to Figures 1-4 The present application provides a technical solution:
[0023] Please refer to Figures 1-4 Fig. 1 is a kind of lamp of injection molding soft glue waterproof structure mode, including rear cover 1 and front cover 5, encapsulation 2, it is set on rear cover 1;Round hole 7, it is set in the bottom of rear cover 1;Multiple upper triangular ribs 10, it is annularly sequentially fixedly installed on front cover 5;Multiple lower triangular ribs 11, it is annularly sequentially fixedly installed on rear cover 1, upper triangular rib 10 and lower triangular rib 11 are matched, upper triangular rib 10 and lower triangular rib 11 are mutually matched and the side of encapsulation 2 is extruded, front cover 5 contacts encapsulation 2 and the top of encapsulation 2 is pressurized to make encapsulation 2 present C character shape, meanwhile, the inside of encapsulation 2 will form tight closed cavity.
[0024] First, encapsulation 2 is tightly connected on rear cover 1 in C character shape, this special-shaped encapsulation can preliminarily adhere to the profile of rear cover 1, and lay a foundation for subsequent waterproof sealing, when lamp assembly is carried out, front cover 5 gradually approaches encapsulation 2, in the instant of contact, front cover 5 exerts pressure on the top of encapsulation 2, and at the same time, multiple upper triangular ribs 10 that are annularly sequentially fixedly installed on lampshade 6 and multiple lower triangular ribs 11 that are also annularly arranged on rear cover 1 are mutually matched and tightly matched, they jointly act on the side of encapsulation 2 and extrude it, this double extrusion from top and side makes encapsulation 2 deform, and then forms tight closed cavity in the inside of encapsulation 2, the formation of closed cavity is crucial, it can effectively block the moisture, dust and other impurities in the outside from entering the inside of lamp, because there is no direct passage for outside substances to penetrate, so as to ensure the waterproof and dustproof performance of lamp.
[0025] In addition, the round hole 7 arranged at the bottom of the rear cover 1 plays a key role in connecting the whole, which connects the upper and lower rubber-coated parts 2 to form a complete whole. After the lamp is assembled, even if screws are used to fix the front cover 5 and the rear cover 1, and the front cover 5 and the rear cover 1 are extruded and deformed due to assembly, since the rubber-coated part 2 is connected into a whole by the round hole 7, the rubber-coated part 2 will not be squeezed out due to uneven force and cause overflow, and always maintain a stable sealing state, avoiding the problem that waterproofing and dustproofing are invalid due to displacement of the rubber-coated part 2, and comprehensively ensuring reliable operation of the lamp in various complex environments.
[0026] Referring to Figures 1-2 , the top of the front cover 5 is fixedly installed with a lampshade 6, and the lampshade 6 is in a circular arc shape.
[0027] In combination with the injection-molded soft rubber waterproof structure of the lamp, the circular arc-shaped lampshade 6 is more closely and naturally connected with the front cover 5. In terms of waterproofing, since the shape and the soft rubber sealing structure cooperate with each other, when rainwater or other liquids contact the lampshade 6, they will slide along the circular arc surface, reducing the opportunity for the liquids to stay and penetrate on the surface of the lampshade 6. In terms of dustproofing, the circular arc design reduces the accumulation of dust on the lampshade 6, so that the dust is more easily taken away by natural factors such as wind blowing and vibration.
[0028] Referring to Figures 1-2 , the inner diameter of the front cover 5 is greater than the diameter of the rear cover 1, and the front cover 5 is sleeved on the top of the rear cover 1.
[0029] The inner diameter of the front cover 5 is greater than the diameter of the rear cover 1, and this sleeving manner can form a structure similar to a cap. When rainwater or other liquids contact the lamp, the liquids will first flow along the outer surface of the front cover 5. Since the front cover 5 is sleeved on the top of the rear cover 1, it is difficult for the liquids to directly enter the joint between the rear cover 1 and the front cover 5, and this structure makes the liquids more inclined to slide from the edge of the lamp under the action of gravity rather than penetrate into the interior.
[0030] This effectively reduces the possibility of external moisture entering the interior of the lamp, enhances the waterproof performance of the lamp, and better protects the electronic components and light sources in the interior of the lamp when used outdoors or in a humid environment, reduces the risk of damage to the lamp due to water ingress, and prolongs the service life of the lamp. For example, in outdoor street lamps, landscape lamps, or some lamps used near swimming pools, this structure can significantly improve the waterproof ability of the lamp.
[0031] Referring to Figure 1 , the bottom of the rear cover 1 is threadedly connected with a fixing bolt 8, the fixing bolt 8 is sleeved with a small sealing ring 9, the small sealing ring 9 abuts against the bottom of the rear cover 1, and the rear cover 1 is fixedly connected with the front cover 5 through the fixing bolt 8.
[0032] When the fixing bolt 8 fixes and connects the rear cover 1 and the front cover 5, the small sealing ring 9 sleeved on the fixing bolt 8 abuts against the bottom of the rear cover 1. During the process of tightening the fixing bolt 8, the bolt exerts pressure on the small sealing ring 9, so that the small sealing ring 9 is elastically deformed, thereby filling the small gap between the fixing bolt 8 and the rear cover 1. This sealing mode can effectively prevent water from entering the inside of the lamp from the mounting position of the fixing bolt 8.
[0033] Referring to Figure 1 , the tail cable 3 and the emergency light source power module 4 are arranged between the front cover 5 and the rear cover 1, and the emergency light source power module 4 is arranged above the tail cable 3.
[0034] The arrangement of the emergency light source power module 4 enables the lamp to have an emergency lighting function. Under normal power supply conditions, the lamp works in a conventional manner. When an emergency such as power failure occurs, the emergency light source power module 4 can provide a backup power supply for the lamp, so that the emergency light source is lit, and the tail cable 3 plays a role in connecting various components inside the lamp. It can ensure that the emergency light source power module 4 and other parts of the lamp such as the light source, the control circuit and the like achieve effective electrical connection, and ensure the normal implementation of the emergency lighting function.
[0035] Referring to Figure 1 , the fixing bolt 8 and the small sealing ring 9 are arranged in a ring shape at equal intervals on the rear cover 1, and the material of the small sealing ring 9 is rubber.
[0036] The ring-shaped and equidistantly distributed fixing bolt 8 and small sealing ring 9 make the connection between the rear cover 1 and the front cover 5 more stable. When subjected to external impact or vibration, multiple fixing bolts 8 can jointly bear the force, avoiding local overloading and causing the connection to loosen. At the same time, the small sealing ring 9 made of rubber can generate a certain friction force after being extruded, and due to its elasticity, it can play a buffering role, further enhancing the anti-vibration performance of the connection.
[0037] Referring to Figures 1-2 , the lampshade 6 is made of polycarbonate material.
[0038] Polycarbonate is a dense material with a relatively tight molecular structure, and water molecules are difficult to penetrate. This material itself has certain waterproof performance, and it can prevent water from spreading inside the material. Unlike some porous or loose materials, polycarbonate will not absorb water, thereby avoiding the gaps caused by the swelling and deformation of the material after absorbing water, which may cause further water penetration into the inside of the lamp.
[0039] Referring to Figure 1 , the diameter of the small sealing ring 9 is greater than the diameter of the nut of the fixing bolt 8.
[0040] When the small sealing ring 9 with larger diameter is pressed by the fixing bolt 8, it will generate greater friction and elastic deformation force, which not only enhances the sealing effect, but also provides additional tightening force for the fixing bolt 8 to a certain extent. If the fixing bolt 8 shows signs of slight loosening due to long-term vibration or other reasons, the small sealing ring 9 with larger diameter and good elasticity can compensate for this loosening to a certain extent, maintaining the stability of the sealing and connection.
