Description

Technical Field

[0001] The present application relates to the technical field of road traffic signal lamps, and in particular to a traffic signal lamp having an integrally formed front shell and a rear shell, which are flexibly connected by an external planar soft hinge and flexibly fixed by a flexible rubber ring. Background Art

[0002] With the accelerated development of global urbanization, urban traffic management has become increasingly complex and challenging. As the core component of the traffic management system, the scientific and practical design of traffic lights is directly related to traffic efficiency and safety. However, the existing traffic light system faces many problems in shell sealing and fixing, which not only affects the normal operation of the lights, but also increases maintenance costs, bringing challenges to the efficiency and reliability of traffic management.

[0003] When assembling traditional traffic lights, the light unit, the shade edge, the light housing and other parts are usually fixed and connected with multiple small parts such as screws, washers and fasteners. These parts need to be manually assembled one by one during the installation process, which is cumbersome, time-consuming and error-prone. In addition, due to the involvement of multiple connection points, the interfaces of multiple components are prone to the intrusion of moisture, dust and other substances due to poor sealing, which affects the normal operation of electronic equipment, often making it difficult to ensure long-term stability and reliability, and even causing the traffic light to fail, increasing the risk of traffic accidents.

[0004] When traditional traffic lights are installed, their fixed brackets are usually connected to the signal light housing by bolts or welding. Although this design can meet the installation requirements to a certain extent, it has several disadvantages. First, the separate bracket structure requires additional processing steps during the production process, which increases the production cost and may affect the overall stability of the structure. Secondly, during on-site installation, the fixed bracket needs to be accurately positioned and fixed on the signal light pole, which not only increases the installation time, but also requires the installers to have a certain level of technical skills. In addition, a variety of tools and auxiliary equipment may be required during on-site installation, further increasing the complexity and cost of installation.

[0005] The maintenance or replacement of traditional traffic lights is also time-consuming and laborious. Due to the complexity of the shell fixing method, maintenance personnel often need professional tools and a long time to open the shell when inspecting or replacing damaged parts. This not only increases maintenance costs, but may also cause traffic congestion due to long maintenance time, especially in busy urban areas or main roads. For traffic lights located at high altitudes, maintenance personnel also need to use lifting platforms or climbing facilities, which further increases the difficulty and risk of the work.

[0006] Therefore, in order to solve the many shortcomings of traditional traffic lights in terms of shell sealing and assembly, a more efficient, reliable and economical solution is urgently needed and has great value in the technical innovation of traffic lights. Summary of the invention

[0007] The purpose of the present application is to provide a traffic light with an integrally formed external flexible fixed plane soft hinge, the core of which is an integral shell sealing and fixing mechanism. This new fixing structure adopts the design concept of dual fixing and sealing of flexible hinges and fastening rubber rings, simplifying the traditional multi-part, multi-step fixing and sealing process into a continuous, integrated operation. It greatly reduces the number and types of parts during assembly, simplifies the installation process, and makes the installation process of the signal light faster and more economical.

[0048] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0050] Combination Figure 1 to Figure 5 As shown, a traffic signal light with an integrally formed external flexible fixed plane soft hinge comprises:

[0051] A first housing 1;

[0052] A second shell 2, arranged opposite to the second shell 2;

[0053] A fixing assembly 3, used for connecting and fixing the first shell 1 and the second shell 2;

[0054] A mounting bracket 4 is used for fixing the signal light to the signal light pole;

[0055] The first shell 1 is fixed with a light source circuit board 5 , a light source mask 6 and a shielding edge 7 , and a closed cavity is provided between the first shell 1 and the second shell 2 for placing a transformer 8 and a control unit 9 .

[0056] A specific embodiment provided in this application describes in detail the components of a traffic signal light with an integrally formed external flexible fixed plane soft hinge in this application as follows:

[0057] The closed cavity, located between the first shell 1 and the second shell 2, is specially designed to accommodate the transformer 8 and the control unit 9, ensuring the protection and integration of the internal components.

[0058] The fixing assembly 3 is used to achieve a stable connection between the first shell 1 and the second shell 2, and ensure the sealing and durability of the structure.

[0059] The fixing ear 22 is designed as an integral structure with the second shell 2, which simplifies the installation process and improves the overall strength. The fixing ear 22 and the second shell 2 are designed as an integral structure, which has the advantages of reducing the number of parts, enhancing the strength of the fixing ear 22, and improving the stability of the fixed mounting bracket 4.

[0060] During the installation of traffic lights, due to the layout of the intersection road and the position of the signal light pole, it is often encountered that the signal light pole is not perpendicular to the road. In this case, if the angle of the signal light cannot be adjusted, the signal light will not be correctly aligned with the road, affecting the accuracy of the traffic indication. The present application solves this problem by fixing the hanging ear 22 and the mounting bracket 4 in an adjustable connection, as follows:

[0061] like Fig. 9 As shown, a tooth-shaped limiting groove 221 is provided inside the fixing ear 22. Fig.10 As shown, toothed ears 41 are provided on both sides of the mounting bracket 4, and the toothed ears 41 include a plurality of saw teeth 411. The shape and size of the toothed limiting groove 221 are the same as those of the saw teeth 411. Fig.11 As shown, by inserting the serrations 411 of the toothed ear piece 41 at different angles into the toothed limit groove 221, the angle adjustment of the mounting bracket 4 is completed, thereby achieving fine adjustment of the angle of the signal light, so that the signal light can adapt to traffic signal light poles of various angles, ensuring that the signal light can be aimed at the road, and improving the accuracy and safety of traffic instructions.

[0062] like Figure 8 As shown, the first extended lip 11 and the second extended lip 21 extend outward from the first shell 1 and the second shell 2 respectively, and fit together to form a closed platform to enhance the sealing and integrity of the structure.

[0063] The flexible hinge 31 is preferably a high-strength flat adhesive tape, such as Figure 6 As shown, it is arranged on any long side of the closed platform, allowing the first shell 1 and the second shell 2 to be flexibly opened and closed within a certain range while maintaining the stability of the connection.

[0064] The fastening rubber ring 32 is preferably made of a high-strength, weather-resistant material, such as Figure 7 As shown, the entire closed platform is surrounded to strengthen the sealing effect between the first shell 1 and the second shell 2 to prevent moisture and dust from entering. The signal light can be disassembled and assembled without tools, parts are simplified, maintenance frequency is reduced, and maintenance costs are reduced.

[0065] The first recessed space and the second recessed space are respectively formed between the first extended lip 11 and the first shell 1 and between the second extended lip 21 and the second shell 2, providing a limit for the fastening rubber ring 32 to ensure its correct position, enhance the sealing performance, and enhance the overall reliability.

[0066] The light source accommodating cavity 12 is sunken into the inner surface of the first shell 1 , and its depth precisely matches the total thickness of the light source circuit board 5 and the light source mask 6 to achieve a compact layout and facilitate the firmness of the connection between the light source circuit board 5 and the first shell 1 .

[0067] The light source circuit board 5 and the light source mask 6 are tightly matched and placed in the light source accommodating cavity 12, wherein the outer side of the light source circuit board 5 is flush with the surface of the first shell 1 and is fixed by an adhesive tape to ensure the stability of the light source.

[0068] The engaging groove 13 protrudes from the outer surface of the first housing 1 and is specially designed to fix the shielding edge 7 to protect the signal light from the influence of bad weather and prolong the service life.

[0069] It is worth noting that this embodiment only shows a preferred implementation method of a traffic light with an integrally formed external flexible fixed plane soft hinge, and the traffic light with an integrally formed external flexible fixed plane soft hinge provided by the present application is not limited to this implementation method; the specific shape, position, angle, quantity, etc. can be set according to the needs of actual application.
