Description

Technical Field

[0001] This utility model belongs to the field of automotive instrument panel technology, specifically an automotive instrument panel body with integrated wiring harness channels. Background Technology

[0002] With the rapid development of the automotive industry, the design and functional integration of the automotive dashboard, as a crucial component of the vehicle interior, has gradually become a key aspect in enhancing vehicle performance and user experience. Modern automobiles require dashboards that go beyond aesthetics and functionality, also considering factors such as space utilization, ease of assembly, and ease of maintenance. However, existing automotive dashboards still have certain limitations in terms of structural design and functional integration, particularly in wiring harness layout and channel integration, making it difficult to meet the current automotive industry's demands for efficient and compact designs.

[0003] A search revealed a car dashboard with publication number CN116118500A. This design, through the integration of an outer frame, dashboard body, and heat dissipation vents, along with connectors and guide screws, achieves a stable connection between the dashboard and the frame while optimizing airflow. However, this design does not address the integration of the wiring harness channel. The wiring harness arrangement still requires additional space and fixing devices, resulting in a complex overall structure and occupying more interior space. Furthermore, because the wiring harness channel is not integrated with the dashboard body, loosening or misalignment of the wiring harness is prone to occur during assembly, affecting subsequent maintenance efficiency.

[0004] Another disclosure, CN114290899A, concerns an automotive instrument panel assembly and vehicle. This design enhances the functionality and aesthetics of the instrument panel through the integration of a front defrost cover and defrost duct, while also improving the reliability of connections between components. However, this design also fails to consider the integration of wiring harness channels, relying on external additional structures for wiring harness arrangement, increasing assembly difficulty and material costs. Furthermore, the lack of unified planning for wiring harness channels may lead to wiring harness failure due to vibration or wear during long-term use, thereby affecting the normal operation of the instrument panel and related electronic equipment.

[0005] The aforementioned problems indicate that current automotive dashboards on the market still have shortcomings in terms of functional integration and structural optimization, especially in the design of the wiring harness channel, which fails to achieve integrated integration with the dashboard body. This leads to problems such as complex assembly, low space utilization, and inconvenient maintenance. Therefore, there is an urgent need for an automotive dashboard body that can integrate the wiring harness channel to overcome the shortcomings of existing technologies and provide a more efficient, compact, and easy-to-maintain solution.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-5 As shown, the technical solution of this utility model includes an instrument panel body 1, an embedded wiring harness channel 2, and a modular fixing assembly 3. These components achieve integrated wiring harness arrangement with the instrument panel body through integrated design, significantly improving the utilization of vehicle interior space and simplifying the assembly process. The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] First, the instrument panel body 1 is the core structure of the entire device, and it is made entirely of high-strength engineering plastic, possessing excellent impact resistance and durability. An embedded wiring harness channel 2 is located on the inner edge of the instrument panel body 1. This channel is integrated with the instrument panel body 1 using a one-piece molding process, ensuring the integrity and stability of the structure. The design path of the embedded wiring harness channel 2 has been optimized to minimize the wiring harness length and avoid spatial interference with other components. This optimized path design not only improves the rationality of the wiring harness arrangement but also reduces signal attenuation problems caused by excessively long wiring harnesses. In practical applications, the top of the embedded wiring harness channel 2 is designed with a quick-access cover 4. This cover is magnetically connected to the embedded wiring harness channel 2, facilitating quick opening and re-closing during maintenance.

[0026] The inner wall of the embedded wiring harness channel 2 is equipped with a flexible protective layer 5, which is made of high-temperature resistant and wear-resistant silicone material. This layer effectively reduces vibration and friction damage to the wiring harness during long-term use. The design of the flexible protective layer 5 fully considers various stress factors that the wiring harness may experience during vehicle operation, such as high-frequency vibration, temperature changes, and mechanical friction. By incorporating the flexible protective layer 5, the service life of the wiring harness can be significantly extended, and the risk of failure due to wiring harness damage can be reduced. The surface of the flexible protective layer 5 is smooth and has a certain degree of elasticity, providing additional protection during wiring harness installation and maintenance.

[0027] Modular fixing components 3 are distributed at key nodes of the embedded wire harness channel 2 for segmented fixing and guiding of the wire harness. Modular fixing components 3 include a detachable snap-fit ​​structure 6 and a flexible clamping element 7. The snap-fit ​​structure 6 is screwed onto the outside of the embedded wire harness channel 2, and the flexible clamping element 7 automatically adjusts the clamping force according to the wire harness diameter, ensuring the stability and flexibility of the wire harness arrangement. The connection method of the snap-fit ​​structure 6 and the flexible clamping element 7 is clearly visible, and its design fully considers the convenience and reliability in actual operation. During assembly, the operator only needs to tighten the snap-fit ​​structure 6 to complete the fixing, while the flexible clamping element 7 can automatically adjust the clamping force according to the actual size of the wire harness, thereby avoiding problems caused by excessive or insufficient clamping force. In addition, the design of the modular fixing components 3 also allows for quick replacement or adjustment when needed, further improving the flexibility of wire harness maintenance.

[0028] The snap-fit ​​structure 6 includes snap-fit ​​flaps 61 and adjusting pieces 62. There are four snap-fit ​​flaps 61, and each adjacent snap-fit ​​flap 61 is provided with an adjusting piece 62. The adjusting piece 62 is connected to the snap-fit ​​flap 61 in an elastic adjustment manner to better fix and guide according to the thickness of the wire harness. The narrow end of the snap-fit ​​flap 61 is made of rubber to better provide stability for screw-fit fixing.

[0029] The elastic clamping component 7 includes a fixed base 71, a card holder 72, and an airbag 73. The fixed base 71 is magnetically fixed in a groove on the inner bottom wall of the embedded wire harness channel 2. The top of the card holder 72 has a semi-circular arc structure, and the bottom end of the card holder 72 slides between the inner walls of the top groove of the fixed base 71 in an elastic adjustment manner. A guide shaft for limiting the movement of the card holder 72 is installed in the top groove of the fixed base 71, and a spring is installed on one of the guide shafts. Airbags 73 are installed on the inner arc surfaces of both card holders 72 to facilitate self-adjustment according to the size of the wire harness.

[0030] The back of the instrument panel body 1 is equipped with a reinforcing rib structure 8, which forms an integral support frame with the outer wall of the embedded wiring harness channel 2, thereby improving the overall rigidity and deformation resistance of the instrument panel. The reinforcing rib structure 8 is rationally laid out and evenly distributed, and its shape and size have been precisely calculated to ensure sufficient support strength while reducing weight. The presence of the reinforcing rib structure 8 not only enhances the structural stability of the instrument panel body 1, but also provides additional protection for the embedded wiring harness channel 2, preventing it from deforming or being damaged by external impacts during vehicle operation.

[0031] In practical applications, the working principle of this invention is as follows: After vehicle assembly, the wiring harness is arranged through the embedded wiring harness channel 2, with its path optimized to reduce length and spatial interference. Once inside the embedded wiring harness channel 2, the flexible protective layer 5 provides comprehensive protection against damage caused by vibration or friction. Subsequently, the wiring harness is segmented and guided by the modular fixing assembly 3, and the elastic clamping member 7 automatically adjusts the clamping force according to the wiring harness diameter, ensuring the stability and flexibility of the wiring harness arrangement. During daily use, if maintenance or repair of the wiring harness is required, operators can quickly access the interior of the embedded wiring harness channel 2 by opening the quick-access cover 4, and then close the cover again to restore the original state. Furthermore, the reinforcing rib structure 8 ensures the structural stability of the instrument panel body 1 under various operating conditions, avoiding deformation problems caused by external impacts or long-term use.

[0032] In summary, this utility model, by incorporating key components such as the embedded wiring harness channel 2, the modular fixing assembly 3, and the quick-access cover 4, achieves an integrated design of the wiring harness arrangement and the instrument panel body, significantly improving the utilization of interior space and simplifying the assembly process. Simultaneously, the design of the flexible protective layer 5 and the reinforcing rib structure 8 further enhances the reliability and durability of the device, providing strong protection for the safe operation of the vehicle.
