Description

Technical Field

[0001] This utility model relates to the field of instrument technology, and in particular to a combined instrument assembly. Background Technology

[0002] An instrument cluster is a single unit that integrates various indicators, warning lights, indicator lights, and related control units and displays. It is installed on the dashboard behind the steering wheel, directly in front of the driver, and serves as the primary interface for information exchange between the driver and the vehicle.

[0003] The screen is directly exposed to the external environment and is easily affected by impacts or scratches; the cover material lacks sufficient wear resistance, and the clarity decreases after long-term use; the circuit board components are often directly fixed inside the housing, and the connector layout is scattered, which increases the assembly complexity.

[0004] Therefore, we propose a combined instrument cluster. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a combined instrument assembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: The instrument cluster assembly includes: The front frame has a mounting groove on one side, and a screen and a glass cover plate are fixed in the mounting groove. The screen is located between the front frame and the glass cover plate. The circuit board is fixed on the side of the front frame away from the mounting slot, and a composite plug, a USB plug and a speaker are fixed on one side of the circuit board. The rear cover is fixed to one side of the front frame. A first clearance hole, a second clearance hole, and multiple through holes are provided on one side of the rear cover. The circuit board is located inside the rear cover. The composite plug passes through the first clearance hole, the USB plug passes through the second clearance hole, and the through holes correspond to the speaker.

[0007] In one possible design, the glass cover is made of soda-lime glass.

[0008] In one possible design, a protective film is provided on one side of the glass cover, and the protective film is made of PET.

[0009] In one possible design, two first ear plates are integrally formed on both sides of the front frame, and a first mounting hole is provided through one side of the first ear plate.

[0010] In one possible design, a plurality of grooves are provided on one side of the first ear plate, and the grooves are arranged around the first mounting hole.

[0011] In one possible design, the rear shell has a second ear plate integrally formed on both sides. Two second mounting holes are opened through one side of the second ear plate, and screws are inserted into the second mounting holes. The screws are threadedly connected to the front frame. Beneficial effects

[0012] The screen is positioned between the front frame and the glass cover, effectively isolating it from external impacts and scratches and reducing the risk of damage from direct screen exposure. The rear cover features a first clearance hole, a second clearance hole, and multiple through holes, allowing the composite connector and USB connector to pass through and be exposed externally for easy connection to external devices. Simultaneously, the speaker transmits sound through these through holes. This integrated design reduces the dispersion of connector layout and simplifies the assembly process.

[0013] The glass cover is made of soda-lime glass, which enhances surface hardness and wear resistance, maintaining high optical clarity even after long-term use. A screen protector made of PET material is applied to one side of the glass cover, further enhancing scratch and impact resistance and extending screen lifespan. The grooves on the first ear plate surround the first mounting hole, helping to distribute installation stress and reduce the risk of structural deformation. The integrated second ear plates on both sides of the rear shell are connected to the second mounting hole via screws and threads to the front frame, ensuring a tight fit between the front and rear shells and improving overall structural rigidity and assembly efficiency.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] In one embodiment: Refer to Figures 1-4 The instrument cluster assembly includes a front frame 3. A mounting groove 8 is machined into one side surface of the front frame 3. The dimensions of the mounting groove 8 are adapted to the shape of the screen 18 and the glass cover 1. The screen 18 and the glass cover 1 are fixedly mounted in the mounting groove 8. One side of the screen 18 is fitted with the bottom of the mounting groove 8 of the front frame 3, and the other side is fitted with the glass cover 1, so that the screen 18 is exactly between the front frame 3 and the glass cover 1. This arrangement allows the glass cover 1 to directly contact the external environment. When encountering minor collisions or scratches, the glass cover 1 can withstand the external force first, preventing the screen 18 from being directly exposed and damaged. In daily use, this effectively reduces the probability of cracks and scratches on the screen 18.

[0018] On the side of the front frame 3 away from the mounting slot 8, a circuit board 9 is installed by screws or clips. The edge of the circuit board 9 has a pre-installed fixing structure to fit the front frame 3, ensuring that the circuit board 9 will not loosen or shift after installation. On the side of the circuit board 9 facing away from the front frame 3, the composite plug 12, USB plug 13, and speaker 14 are all connected to the corresponding circuit interfaces on the circuit board 9 by soldering. The positions of the three are arranged according to actual usage requirements. Usually, the composite plug 12 and USB plug 13 are horizontally side by side, and the speaker 14 is placed on one side of the two. After soldering, it is necessary to ensure that the circuit conduction between each component and the circuit board 9 is stable to avoid poor contact that could lead to functional failure.

[0019] The back cover 4 is fixed to the side of the front frame 3 where the circuit board 9 is installed by screws. After installation, the circuit board 9 is completely within the space enclosed by the back cover 4 and the front frame 3. The back cover 4 can protect the circuit board 9 and the composite plug 12, USB plug 13 and speaker 14 on it from dust and minor impacts. On the back cover 4, a first clearance hole 15 is provided through the position corresponding to the composite plug 12. The diameter of the first clearance hole 15 matches the outer dimensions of the composite plug 12. The end of the composite plug 12 away from the circuit board 9 can pass through the first clearance hole 15 and be exposed to the outside, which is convenient for docking with the corresponding interface of external devices. A second clearance hole 16 is provided through the position corresponding to the USB plug 13. The size of the second clearance hole 16 is also adapted to the USB plug 13, ensuring that the USB plug 13 can pass through smoothly and be exposed to the outside, which meets the needs of external USB devices. In addition, multiple through holes 17 are also provided on the back cover 4. The positions of these through holes 17 correspond to the positions of the speaker 14 on the circuit board 9. The through holes 17 are evenly distributed in a circle, which allows the sound emitted by the speaker 14 to pass through the through holes 17 smoothly and be transmitted to the outside without the volume attenuation caused by the obstruction of the back cover 4.

[0020] The glass cover 1 is made of soda-lime glass, which has a surface hardness of approximately 5.5 on the Mohs scale. Even with slight friction from objects like keys and coins during daily use, it is not easily scratched. Soda-lime glass also has good optical properties, maintaining a light transmittance of over 85% even after long-term use, preventing the content displayed on the screen 18 from becoming blurry due to wear and ensuring users can clearly see the information on the screen 18. On the side of the glass cover 1 away from the screen 18, a screen protector 2 is also attached. The screen protector 2 is made of PET, with a thickness controlled between 0.1-0.2mm. It has a certain degree of flexibility and impact resistance. When a small object impacts the glass cover 1, the screen protector 2 can absorb some of the impact force, reducing the impact on the glass cover 1 and the screen 18. At the same time, the PET material itself has good scratch resistance, further improving the wear resistance of the glass cover 1 and extending the lifespan of the entire screen assembly.

[0021] On both the left and right sides of the front frame 3, there are two first ear plates 5. The first ear plates 5 and the front frame 3 are integrally molded by injection molding to ensure the integrity of the connection and prevent breakage or loosening during subsequent use. A first mounting hole 6 is formed through one side surface of each first ear plate 5. The diameter of the first mounting hole 6 is set according to the specifications of the fasteners required for subsequent installation, facilitating the installation of the entire instrument cluster assembly onto the target device using bolts and other fasteners. On the side of each first ear plate 5 where the first mounting hole 6 is located, multiple grooves 7 are also formed. These grooves 7 are evenly distributed around the first mounting hole 6, typically four on each first ear plate 5. When fasteners are installed through the first mounting hole 6, stress is generated on the first ear plate 5 during tightening. The distributed grooves 7 disperse this stress to different areas of the first ear plate 5, preventing stress concentration around the first mounting hole 6 and thus avoiding deformation of the first ear plate 5. This ensures the structural stability of the first ear plate 5 and, consequently, the stability of the instrument cluster assembly after installation.

[0022] This application can be used in the field of instrumentation, or in other fields applicable to this application.

[0023] In another embodiment: a combined instrument assembly, which is applied to the field of instrumentation; In another aspect of this embodiment, second ear plates 10 are integrally formed on both the left and right sides of the rear housing 4. The second ear plates 10 and the rear housing 4 are formed in one piece by injection molding, resulting in high structural strength. Two second mounting holes 11 are formed through one side surface of each second ear plate 10. The two second mounting holes 11 are arranged vertically, and their diameters are adapted to the specifications of the mounting screws. When installing the rear housing 4, the screws are passed through the second mounting holes 11, then aligned with the corresponding threaded holes on the front frame 3 and tightened to ensure a tight fit between the two, thereby improving the structural rigidity of the entire instrument cluster assembly. At the same time, this screw connection method is simple to operate, requires no complicated tools, and can effectively save time and improve assembly efficiency during the assembly process.

[0024] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
