Description

TECHNICAL FIELD

[0001] The utility model relates to vehicle-mounted beidou equipment technical field, concretely to a vehicle-mounted beidou main machine with pilot lamp. BACKGROUND

[0002] The pilot lamp design in the existing vehicle-mounted beidou equipment is mainly used to display the working state of the equipment, but the traditional design has problems such as large installation space occupation, difficult waterproof performance guarantee, insufficient electromagnetic compatibility, etc. The vertical pilot lamp needs to be installed vertically and occupies a large amount of vertical space, which is not suitable for miniaturized or compactly designed equipment. Although the traditional horizontal pilot lamp saves vertical space, its structure is complex and occupies horizontal space, which affects the equipment layout.

[0003] In addition, whether it is a traditional vertical pilot lamp or a horizontal pilot lamp, the mounting hole thereon is usually difficult to achieve reliable sealing and waterproofing, which can easily cause the equipment in a humid environment to fail, and the electromagnetic shielding measures cannot be effectively combined with the light guide structure, resulting in prominent electromagnetic interference problems, so that the existing vehicle-mounted beidou equipment with a pilot lamp is difficult to have good sealing and electromagnetic compatibility performance while ensuring compact structure.

[0004] In view of the above situation, in order to overcome the above technical problems, the utility model designs a vehicle-mounted beidou main machine with a pilot lamp, which solves the above technical problems. SUMMARY

[0005] The technical purpose to be achieved by the utility model is to form a sealed electromagnetic compatibility space by the front end of the light guide assembly contacting the main machine shell, and then to set a horizontal pilot lamp on the circuit board, guide the light through the light guide column, thereby solving the problem of poor sealing and electromagnetic compatibility performance of the pilot lamp in a compact space.

[0006] In order to achieve the above technical purpose, the utility model provides the following technical scheme:

[0007] The vehicle-mounted beidou main machine with a pilot lamp provided by the utility model comprises a main machine shell and a circuit board, further comprises a pilot lamp and a light guide assembly, and the main machine shell serves as the carrier of the overall structure to ensure that each component can be stably installed and connected to the circuit board. The multiple pilot lamps installed in linear array on the circuit board emit light sources at the side to display the working state of the circuit board. Through pilot lamps of different colors, the running state of the equipment (such as normal operation, warning or failure, etc.) can be intuitively reflected.

[0008] The light guide assembly is installed on the main machine shell and located directly in front of the light source of the pilot lamp, and the light guide assembly guides the light source of the pilot lamp to the outer surface of the main machine shell for display. The light guide assembly can effectively transmit the light source and ensure concentrated light display without light leakage or affecting the appearance.

[0009] Meanwhile, both the front end of the light guide component and the main housing are made of 6061 aluminum alloy, which creates an electromagnetic compatibility cavity inside the light guide component, further providing a seal and ensuring that electromagnetic fields and external humid air cannot affect the internal components. Therefore, the use of the light guide component improves the external display effect of the device while avoiding the influence of the external environment on the performance of the indicator lights.

[0010] The light guide assembly includes a light shield, a light guide bracket, and a light guide column. The light shield is mounted on the circuit board and located above the indicator light. The light shield not only prevents light source leakage but also avoids interference between light sources of different indicator lights, ensuring the independence and display clarity of each indicator light. The bottom of the light shield has a light source cavity for accommodating the indicator light.

[0011] In traditional indicator light designs, especially when multiple indicators are arranged, cross-lighting can easily occur, affecting the visual effect. However, by using a light-shielding plate and designing a reasonable light source cavity structure, the light source can be effectively isolated, avoiding cross-lighting and improving the display effect.

[0012] A light guide bracket is disposed in front of the light shield and on the main housing. The light guide bracket has mounting holes for mounting light guide columns extending outwards from the main housing. The light guide columns are made of PMMA material, which has excellent light transmittance, effectively reducing light source loss, and is also UV resistant and age-resistant. The PMMA light guide columns ensure stable light guiding performance and extend the lifespan of the device.

[0013] The light-shielding panel is made of POM (polyoxymethylene), which has good antistatic properties, strength, and wear resistance, effectively ensuring the function of the light-shielding panel.

[0014] The rear end of the light source cavity is a closed arc-shaped groove, and the front end is a rectangular opening pointing towards the light guide post. The rectangular opening of the light source cavity precisely guides light towards the light guide post, ensuring that the light source accurately enters the light guide post and reducing the risk of light deviation or failure. The rectangular shape ensures a perfect match between the opening and the contact surface of the light guide post, further improving the stability and accuracy of the light guide.

[0015] The light guide bracket is made of 6061 aluminum alloy, which not only has good mechanical strength and corrosion resistance, but also good electromagnetic shielding capabilities. The combination of the light guide bracket and the main unit housing forms a sealed and shielded space, ensuring that electromagnetic interference from the indicator light is effectively isolated and guaranteeing electromagnetic compatibility.

[0016] The main housing has light guide holes for mounting the light guide post; the depth of the light guide hole is not less than three times its diameter. The light guide hole ensures stable installation of the light guide post and guarantees good electromagnetic compatibility through a reasonable hole depth design. The reasonable hole depth not only ensures the firmness of the installation but also effectively prevents the entry of external electromagnetic interference.

[0017] The light guide post is provided with mounting ribs. The mounting groove is located in the mounting hole on the light guide bracket, and its function is to ensure the stable installation of the light guide post by locking the mounting ribs on the light guide post. The mounting groove allows the light guide post to be inserted more accurately and locked in the light guide bracket, avoiding the light guide post from affecting its light guiding effect due to loose installation.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. This utility model guides the light source of a horizontally mounted indicator light by setting a light guide component. The light guide column inside the light guide component guides the light source, and the light guide bracket and the aluminum alloy material of the main unit housing further limit the light guide column and the indicator light to be in a relatively sealed and electromagnetically compatible space. This achieves good sealing, waterproofing and electromagnetic compatibility performance in a compact space.

[0020] 2. The light guide bracket of this utility model is installed on the main unit housing, while the light shield is installed on the circuit board. The light guide bracket forms an electromagnetic compatibility module with the main unit housing in front, and the light shield forms a light source module with the indicator light in the back. The two are closely attached to each other to achieve light transmission. At the same time, the modular design allows the indicator light and the light guide column to be installed separately, which facilitates production and maintenance after the sealing or shielding function is damaged.

[0031] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0032] like Figures 1-7 As shown, a vehicle-mounted Beidou host with indicator lights includes a host housing 1 and a circuit board 2; it also includes indicator lights 3 and a light guide assembly 4. A plurality of indicator lights 3 are linearly arrayed on the circuit board 2, and the side of the indicator lights 3 emits light sources to display the working status of the circuit board 2 through different colors.

[0033] In this embodiment, the light guide component 4 is installed on the main housing 1 and located directly in front of the light source of the indicator light 3. The light guide component 4 is used to transmit and display the light source of the indicator light 3 on the outer surface of the main housing 1. The main housing 1 is made of 6061 aluminum alloy.

[0034] The light guide assembly 4 includes a light shield 41, a light guide bracket 42, and a light guide column 43. The light shield 41 is mounted on the circuit board 2 and located above the indicator lights 3. The light shield 41 is made of POM material; the light shield 41 is made of anti-static POM material, which has high strength and anti-static properties. The light source cavity 411 on the light shield 41 is designed as a single-sided opening to prevent cross-lighting of the indicator lights 3. The front end of the light shield 41 is aligned with the side of the circuit board 2.

[0035] In this embodiment, the rear end of the light source cavity 411 is a closed arc-shaped groove, and the front end is a rectangular opening pointing towards the light guide post 43. Because the rear end of the light source cavity 411 is closed, the entire structure of the light source cavity 411 is more compact, reducing the entry of moisture in humid environments and thus improving the device's waterproof performance. The closed arc-shaped groove and rectangular opening design help enhance the light display effect. Due to the light transmission and concentration design, the external display of the indicator light 3 is clearer, avoiding scattered or uneven light and improving the overall display effect of the device.

[0036] The light guide bracket 42 is provided in front of the light shield 41 and on the main housing 1. The light guide bracket 42 is made of 6061 aluminum alloy. The light guide bracket 42 has a mounting hole 421 inside, which is used to install a light guide column 43 extending outward from the main housing 1.

[0037] In this embodiment, the light guide post 43 is made of PMMA material, and the light guide post 43 is a flat-headed light guide post 43 with a diameter of 3mm, specifically model PLP1-10mm-F.

[0038] In this embodiment, the front end diameter of the light guide post 43 is 2.8mm, and the rear end diameter is 3mm. The light guide post 43 is provided with a mounting rib 431, which has a diameter of 3.2mm and a width of 1.3mm. A mounting groove 422, with a diameter of 3.2mm, is provided within the mounting hole 421, precisely locking the end of the light guide post 43 with the mounting rib 431. The light guide bracket 42 only undergoes surface aluminum alloy anodizing treatment and is not painted, thus ensuring that the mounting hole 421, with a diameter of 3.2mm, can precisely lock the mounting rib 431, preventing it from shifting.

[0039] In this embodiment, a light guide hole 11 is provided on the main housing 1. The depth of the light guide hole 11 is 8.7 mm and the diameter is 2.9 mm. The front end of the light guide post 43 is installed in the light guide hole 11.
