Description

Technical Field

[0001] This utility model belongs to the field of decorative panel technology, specifically relating to a decorative panel for heavy truck cabs. Background Technology

[0002] In heavy-duty truck cab design, the trim panel next to the rest area bed is a crucial component for enhancing driver and passenger comfort. To improve tactile feel and enhance interior aesthetics, the trim panel surface is typically covered with soft-touch materials such as leather or fabric. These soft-touch materials not only soften the harshness of hard trim panels but also provide a more comfortable experience when the driver leans against or touches them, playing a particularly positive role in improving rest quality during long-distance transport.

[0003] The leather or fabric panels on the cab trim of heavy trucks are generally fixed with adhesive. While this provides some initial fixation, the adhesives used often contain volatile organic compounds such as formaldehyde and benzene, resulting in a pungent odor inside the cab. Long-term use can pose a potential health hazard to the driver.

[0004] Once the soft-pack material on the existing heavy-duty truck cab trim panel is fixed with glue, subsequent replacement is extremely inconvenient. If the fabric needs to be replaced due to wear, stains, or personalized needs, it is difficult to completely peel off the old material. Moreover, glue residue or tearing force during the removal process can easily cause scratches, deformation, or even damage to the substrate of the trim panel, resulting in the entire trim panel being scrapped and increasing maintenance costs.

[0032] 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.

[0033] Example 1: Refer to Figures 1-7 A decorative panel for a heavy-duty truck cab, comprising:

[0034] The decorative panel 100 has a storage groove 101 on its side, and the soft-padded fabric is installed on the decorative panel 100 with its edge embedded in the storage groove 101.

[0035] Several positioning heads 200 are fixed to the inner wall of one side of the storage slot 101 to pierce and position the edge of the soft-pack fabric.

[0036] A clamping plate 300 is disposed in the storage groove 101 and is positioned opposite to the positioning head 200. A groove 301 is formed on the surface of the clamping plate 300 facing the positioning head 200.

[0037] The adjustment mechanism 302 extends through the back of the decorative panel 100 and is connected to the clamping plate 300. It is used to drive the clamping plate 300 to move towards the positioning head 200, so that the tip of the positioning head 200 is inserted into the groove 301 to clamp the soft fabric.

[0038] In this embodiment, the storage groove 101 on the side of the decorative panel 100 provides a hidden storage space for the edge of the soft-covered fabric, avoiding direct exposure of the seam. The groove structure seals the raw edge of the fabric, improving the aesthetics and preventing dust from seeping in.

[0039] The positioning head 200 replaces glue to achieve initial positioning of the fabric, restricts the planar displacement of the fabric after puncture, and the needle pre-fixes the edge of the fabric to ensure that the fabric does not shift during subsequent clamping processes. The conical needle tip disperses the puncture stress and avoids fabric tearing.

[0040] The clamping plate 300 and the positioning head 200 work together to form a double mechanical fixation of "piercing-locking", which replaces the adhesive force of glue. Releasing the clamping plate 300 will release the lock and the fabric can be removed completely.

[0041] The entire system adopts a back-mounted adjustment mechanism, which is operated from the back of the decorative panel. This results in a higher degree of flatness and a more aesthetically pleasing appearance on the front of the decorative panel.

[0042] Reference Figure 4 and Figure 7 The adjustment mechanism 302 is a threaded fastener, with its front end threadedly connected to the clamping plate 300 and its rear operating part embedded in the back of the decorative panel 100.

[0043] The clamping plate 300 can be driven to move linearly by rotating the bolt from the back of the decorative panel 100 with a screwdriver or wrench, without removing the front soft-pack material, and the maintenance process does not affect the use of the interior space of the cab.

[0044] The threaded drive has a self-locking feature, which can precisely control the 300° displacement of the clamping plate according to the thickness of the fabric, avoiding the fabric from being deformed due to excessive tightness or falling off due to excessive looseness.

[0045] The countersunk design prevents bolts from protruding from the back of the panel, ensuring a tight fit with the cab wall panel during installation without any protrusions or interference, while also improving the cleanliness of the back of the decorative panel.

[0046] Reference Figure 4 and Figure 7 An adjustment groove 102 is provided on one inner wall of the storage groove 101, and the clamping plate 300 is installed in the adjustment groove 102.

[0047] The positioning head 200 is a tapered needle structure with its tip facing the clamping plate 300.

[0048] The depth of the groove 301 is greater than the protruding height of the positioning head 200.

[0049] The surface of the clamping plate 300 that contacts the soft fabric is provided with an anti-slip texture.

[0050] The anti-slip texture increases the friction between the clamping plate 300 and the fabric surface, especially for smooth leather materials, which can effectively prevent the edges from slipping out due to insufficient clamping force. Together with the positioning head 200, it forms a triple fixation of puncture-friction-locking.

[0051] The operating part of the threaded fastener is a countersunk bolt structure, and its end face is flush with the back of the decorative panel 100.

[0052] Reference Figure 2 The positioning heads 200 are evenly arranged around the circumference of the receiving groove 101.

[0053] The 200-degree circumferentially uniform positioning head layout ensures consistent force distribution at all points along the fabric edge, preventing surface wrinkles caused by excessive local tension. It is especially suitable for smooth bonding of large-area soft padding.

[0054] Example 2: The difference between this example and Example 1 is as follows:

[0055] The adjustment mechanism 302 is an elastic compression component, with its two ends connected to the clamping plate 300 and the inner wall of the storage groove 101, respectively; the elastic compression component is a helical spring or an elastic rubber block.

[0056] Vibrations during heavy truck operation can cause materials to expand and contract or deform slightly. The elastic element absorbs vibration energy through its own deformation and maintains stable clamping force.

[0057] During installation, simply insert the edge of the fabric into the positioning head 200, and the elastic element will automatically push the clamping plate 300 to complete the initial clamping. No additional tools are required, and the replacement time is shortened.

[0058] Non-metallic elastic components such as elastic rubber blocks can absorb frictional noise between the clamping plate 300 and the storage groove 101, and maintain good elasticity, especially in low-temperature environments, to avoid noise caused by rigid collisions of metal parts.

[0059] The working principle and usage process of this utility model are as follows: Cut leather or fabric to fit the front size of the decorative panel 100, leaving a 10-20mm width at the edge for embedding into the storage groove 101; flatten the fabric and attach it to the front of the decorative panel 100, comb the fabric along the edge of the storage groove 101 so that the edge naturally hangs into the groove, forming a preliminary positioning reference; gently pull the edge of the fabric into the storage groove 101 to tighten it, so that the tip of the positioning head 200 pierces the fabric fiber layer, and uses the mechanical piercing force of the needle to fix the position of the fabric edge; the positioning heads 200 are inserted into the fabric in sequence along the circumference of the storage groove 101 to form multi-point support, restrict the lateral / longitudinal displacement of the fabric, and avoid wrinkles or displacement during installation.

[0060] Threaded fasteners: Use a screwdriver / wrench to rotate the bolt from the back of the decorative panel 100, driving the clamping plate 300 to move along the adjustment groove 102 toward the positioning head 200 until the tip of the positioning head 200 is fully inserted into the groove 301 of the clamping plate 300.

[0061] Elastic compression component: After the edge of the fabric is inserted into the positioning head 200, the pre-tightening force of the elastic component in its natural state automatically pushes the clamping plate 300, so that the groove 301 and the positioning head 200 are quickly aligned and locked without the need for additional tools;

[0062] The clamping plate 300 and the positioning head 200 work together to form a piercing-locking composite structure. At the same time, the anti-slip texture on the surface of the clamping plate 300 presses the fabric, forming a triple fixation of piercing force, locking force and friction, ensuring that the edge of the fabric fits tightly against the inner wall of the storage slot 101.

[0063] By adjusting the displacement of the clamping plate 300 through the adjustment mechanism 302, local wrinkles on the fabric surface caused by uneven tension are eliminated, ultimately achieving a flat and flawless front surface for the decorative panel 100.

[0064] Rotate the bolt in the opposite direction to move the clamping plate 300 away from the positioning head 200 until the groove 301 is completely separated from the positioning head 200;

[0065] Elastic compression element: Manually pull the clamping plate 300 to compress the elastic element and release the locking state of the groove 301 on the positioning head 200.

[0066] Gently lift the fabric along the edge of the storage slot 101. The tip of the positioning head 200 smoothly detaches from the fabric fiber layer. The old fabric can be completely removed without tearing. There is no glue residue or scratches on the surface of the decorative panel 100.

[0067] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
