Description

Technical Field

[0001] This utility model relates to the field of automotive instrument structure technology, specifically an all-plastic reinforced automotive instrument structure. Background Technology

[0002] With the automotive industry's pursuit of lightweighting and production efficiency, traditional automotive instrument panels mostly use metal housings or metal-plastic hybrid structures. While these meet strength requirements, they are heavy, increasing overall vehicle energy consumption. Furthermore, the complex metal processing steps and long molding cycles result in high production costs. Subsequent all-plastic instrument panels solved the problems of lightweighting and rapid prototyping, but the inherent rigidity of plastics limits structural strength. Vibrations and impacts during vehicle operation can easily cause localized deformation of the instrument panel housing, such as warping of the display mounting slot, cracking of the instrument panel mounting area, and damage to edges during assembly or collisions. These problems not only affect the assembly accuracy and lifespan of the instrument panel but can also lead to internal circuit and sensor malfunctions due to housing deformation, interfering with the accuracy of driving information display and failing to meet the requirements for long-term reliable vehicle operation. Utility Model Content

[0003] The purpose of this utility model is to provide an all-plastic reinforced automotive instrument structure to solve the problems mentioned in the background art, which are that traditional automotive instruments mostly use metal shells or metal-plastic hybrid structures, which can meet the strength requirements but are heavy, increase the energy consumption of the whole vehicle, and have complex metal processing procedures and long molding cycles, resulting in high production costs.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A fully plastic reinforced automotive instrument panel structure, comprising: The all-plastic instrument housing has an instrument mounting part and a display screen mounting slot on the front outer wall. The inner wall of the instrument mounting part is provided with a reinforcing ring, and the inner wall of the display screen mounting slot is provided with an annular reinforcing frame. The reinforcing structure includes reinforcing ribs, which include transverse reinforcing ribs and longitudinal reinforcing ribs. The transverse reinforcing ribs and longitudinal reinforcing ribs are distributed perpendicularly to each other. The reinforcing structure and the all-plastic instrument housing are integrally injection molded structures.

[0005] In a preferred embodiment of this utility model, a square reinforcing block is formed at the intersection of the transverse reinforcing ribs and the longitudinal reinforcing ribs, and the thickness of the transverse reinforcing ribs and the longitudinal reinforcing ribs is 1.2-1.5 times that of the all-plastic instrument housing.

[0006] In a preferred embodiment of this utility model, the spacing between the transverse reinforcing ribs and the longitudinal reinforcing ribs is 50-80mm, and the spacing between the transverse reinforcing ribs is the same as the spacing between the longitudinal reinforcing ribs.

[0007] In a preferred embodiment of this utility model, the bottom of the all-plastic instrument housing is provided with a reinforcing base plate, and the reinforcing base plate is integral with the all-plastic instrument housing.

[0008] In a preferred embodiment of this utility model, the transverse reinforcing ribs and longitudinal reinforcing ribs are attached to the inner wall of the all-plastic instrument housing to form an integrated structure with the ends connected.

[0009] In a preferred embodiment of this utility model, a heat dissipation hole is provided on the top of the all-plastic instrument housing, and a dustproof mesh is fixedly installed on the inner wall of the heat dissipation hole.

[0010] In a preferred embodiment of this utility model, the instrument mounting part is circular and penetrates the front inner wall of the all-plastic instrument housing.

[0011] In a preferred embodiment of this utility model, the inner wall of the instrument mounting part is provided with a reinforcing ring, and the two ends of the reinforcing ring pass through the front and rear ends of the instrument mounting part and form a covering ring with the outer wall of the instrument mounting part.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0013] 1. By integrating the all-plastic instrument housing with a multi-dimensional reinforced structure, the lightweight advantages of the all-plastic material are retained, reducing the vehicle's energy consumption. At the same time, targeted reinforcement designs, such as mesh reinforcement, wrapping rings, and U-shaped frames, significantly improve the overall rigidity of the instrument and avoid deformation and cracking caused by vibration or installation. 2. High adaptability and reliability: Each reinforced component is designed for key stress points of the instrument, including the mounting part, display slot, edge, and bottom. It can adapt to the assembly requirements of round instruments and vehicles with different vibration intensities. At the same time, the one-piece molded structure reduces the gap between components, extends the service life of the instrument, and ensures stable display of driving information.

Detailed Implementation

[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0017] Example 1: As Figures 1-4 ,include: The all-plastic instrument housing 100 has an instrument mounting part 130 and a display screen mounting groove 140 on the front outer wall. The inner wall of the instrument mounting part 130 is provided with a reinforcing ring 131, and the inner wall of the display screen mounting groove 140 is provided with an annular reinforcing frame 141. The reinforcing structure includes reinforcing ribs, which include transverse reinforcing ribs 200 and longitudinal reinforcing ribs 210. The transverse reinforcing ribs 200 and longitudinal reinforcing ribs 210 are distributed perpendicularly to each other. The reinforcing structure and the all-plastic instrument housing 100 are integrally injection molded structures.

[0018] The specific application scenario of this embodiment is as follows: The all-plastic instrument housing 100 is made of lightweight plastic material, such as glass fiber reinforced PP, which reduces the overall weight from the source and reduces the energy consumption of the whole vehicle; in the key assembly area of ​​the instrument, the reinforcing ring 131 on the inner wall of the instrument mounting part 130 can enhance the tensile and compressive strength of the circular mounting hole and prevent the hole wall from deforming when the instrument is embedded; the annular reinforcing frame 141 on the inner wall of the display mounting groove 140 forms a rigid support for the edge of the display screen and prevents the connection between the display screen and the housing from cracking due to vehicle vibration. At the same time, the transverse reinforcing ribs 200 and the longitudinal reinforcing ribs 210 in the reinforcing structure are vertically intersecting and form a "grid-like support skeleton" that fits against the inner wall of the all-plastic instrument housing 100. Through the one-piece injection molding process, the reinforcing ribs and the housing are seamlessly integrated, which not only avoids the connection gap problem of the traditional metal-plastic hybrid structure, but also evenly distributes the external forces borne by the housing, such as vibration impact and installation stress, to the entire grid skeleton, significantly improving the overall rigidity of the all-plastic housing and ensuring that the instrument is not easily deformed during long-term use.

[0019] Example 2: Figures 1-4A square reinforcing block 220 is formed at the intersection of the transverse reinforcing ribs 200 and the longitudinal reinforcing ribs 210. The thickness of the transverse reinforcing ribs 200 and the longitudinal reinforcing ribs 210 is 1.2-1.5 times that of the all-plastic instrument housing 100. The spacing between the transverse reinforcing ribs 200 and the longitudinal reinforcing ribs 210 is 50-80mm. The spacing between the transverse reinforcing ribs 200 and the longitudinal reinforcing ribs 210 is the same. The bottom of the all-plastic instrument housing 100 is provided with a reinforcing base plate 120, which is integral with the all-plastic instrument housing 100. The transverse reinforcing ribs 200 and the longitudinal reinforcing ribs 210 are attached to the inner wall of the all-plastic instrument housing 100 to form an integral structure with the ends connected. The top of the all-plastic instrument housing 100 is provided with a heat dissipation hole 110, and a dustproof net 111 is fixedly installed on the inner wall of the heat dissipation hole 110.

[0020] The specific application scenario of this embodiment is as follows: the thickness of the transverse reinforcing ribs 200 and the longitudinal reinforcing ribs 210 is set to 1.2-1.5 times that of the all-plastic instrument housing 100, which strengthens the bending resistance of the ribs themselves without excessively increasing the weight; the spacing is controlled at 50-80mm, which is designed through stress simulation to ensure that when any area of ​​the housing is subjected to force, the load can be quickly transferred through adjacent reinforcing ribs, avoiding local stress concentration; the square reinforcing block 220 at the intersection of the two is equivalent to forming a "reinforcing hub" at the grid node, further improving the shear strength of the intersection and coping with the multi-directional stress caused by vehicle bumps. Vibration is mitigated by the reinforced base plate 120 at the bottom of the all-plastic instrument housing 100, which is integrally formed with the housing. Its planar structure increases the contact area between the housing and the vehicle body mounting surface, reduces local pressure, and enhances the anti-sagging ability of the bottom of the housing, preventing the bottom from denting due to the weight of the instrument after long-term use. The heat dissipation holes 110 on the top of the housing can dissipate the heat generated by the internal electronic components in a timely manner, preventing high temperature from affecting the display accuracy and component life. The dustproof mesh 111 fixed on the inner wall can block external dust from entering the inner cavity of the housing, preventing dust from adhering to the display screen or circuit and causing malfunctions, achieving the dual effect of "heat dissipation without dust ingress".

[0021] Example 3: Figure 4 The instrument mounting part 130 is circular and penetrates the inner front wall of the all-plastic instrument housing 100. The inner wall of the instrument mounting part 130 is provided with a reinforcing ring 131. The two ends of the reinforcing ring 131 pass through the front and rear ends of the instrument mounting part 130 and form a covering ring with the outer wall of the instrument mounting part 130.

[0022] The specific application scenario of this embodiment is as follows: The instrument mounting part 130 is set as a circular hole that penetrates the inner wall of the front end of the all-plastic instrument housing 100, which facilitates the instrument to be embedded from the back of the housing and displayed from the front, and is compatible with the conventional assembly process of "front display and rear installation" of automotive instruments; the reinforcing ring 131 of the inner wall penetrates the front and rear ends of the mounting part at both ends and forms a "covering ring" with the outer wall of the mounting part. This structure is equivalent to covering and reinforcing the hole wall from the "inner wall + front and rear end faces" in three directions. It can not only resist the radial extrusion stress during instrument installation, but also prevent the front and rear end faces of the mounting part from being worn or cracked due to long-term friction, such as instrument maintenance and disassembly. This ensures the long-term stability of the assembly accuracy between the instrument and the housing and avoids the instrument display deviation caused by the increase of the installation gap.

[0023] The working principle of this utility model is as follows: When used by those skilled in the art, a lightweight material such as glass fiber reinforced plastic is used to make an all-plastic instrument housing 100. Through an integrated injection molding process, the reinforcing structures such as the transverse reinforcing ribs 200, longitudinal reinforcing ribs 210, square reinforcing blocks 220, reinforcing base plates 120, reinforcing rings 131, and annular reinforcing frames 141 are formed simultaneously with the housing. This ensures the integrity of the connection between each component and reduces the steps and costs of traditional assembly processes. For the core stress points in the use of the instrument, such as the mounting holes, display screen slots, bottom of the housing, and inner walls, a combination design of "local reinforcing parts reinforcing rings, annular reinforcing frames + overall skeleton grid reinforcing ribs" is used to achieve "key protection + comprehensive support". The mounting holes are resistant to deformation, the display screen is resistant to vibration, the housing is resistant to sagging, and the whole is resistant to impact.

[0024] Functional Synergy Guarantee: The heat dissipation vent 110 works in conjunction with the dustproof mesh 111 to balance the heat dissipation and dustproof requirements of the instrument; the all-plastic material reduces weight from the source and reduces the energy consumption of the whole vehicle; the one-piece molding structure eliminates connection gaps, extends the service life of the instrument, and ensures that the instrument display is stable and fault-free during driving.

[0025] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
