Description

Technical Field

[0001] This utility model belongs to the field of automotive trim strips, specifically, it relates to an automotive trim strip with an installation structure. Background Technology

[0002] Automotive trim strips are decorative components installed on the exterior or interior of a vehicle, primarily to enhance its aesthetics while also serving protective and functional purposes. They are typically found on doors, windows, sides, and bumpers, and come in a variety of materials and designs that vary depending on the vehicle model and brand.

[0003] During the installation of trim strips, sound-dampening cotton is usually installed between the car and the trim strips. If drivers and passengers expect a better driving experience, they need to replace it with high-performance sound-dampening cotton, which often increases the cost of use.

[0004] To address these shortcomings, a car trim strip with an installation structure is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an automotive trim strip with an installation structure, thereby solving the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] An automotive trim strip with an installation structure includes a trim strip body and a plurality of first positioning plates fixed to the trim strip body;

[0008] The first positioning plate has a transverse through groove and a vertical groove connected to the transverse through groove. A first guide block is installed on both sides of the transverse through groove. A second positioning plate is elastically fitted on the first guide block. A buffer is provided on the opposite outer side of the two second positioning plates. A first chamfer is provided on the opposite inner side of the two second positioning plates.

[0009] An extrusion block is elastically fitted inside the vertical groove. The beveled surface of the first chamfer faces the extrusion block, and a positioning post is adjustablely installed at the bottom of the extrusion block.

[0010] Optionally, a first guide groove is provided on the second positioning plate, a first guide block is located in the first guide groove, a guide hole is provided on the first guide block, a guide rod is slidably fitted in the guide hole, and a first spring is sleeved on the section of the guide rod near the extrusion block.

[0011] Optionally, the bottom of the extrusion block is provided with a threaded hole, the positioning post is provided with an external thread that is threaded to the threaded hole, and a second guide groove is provided on both sides of the vertical groove. The second guide groove is connected to the transverse through groove, and a second guide block is fixed on both sides of the extrusion block and slides to the second guide groove.

[0012] Optionally, a second spring is fixed on the second guide block, the second spring is located in the second guide groove, and the two sides of the extrusion block that contact the first chamfer are provided with a second chamfer.

[0013] Optionally, multiple support arms, multiple rubber balls, and multiple guide plates are fixed on the trim body. The support arms are provided with a first positioning hole and a second positioning hole, with the second positioning hole located above the first positioning hole.

[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0015] By designing a flexible mounting structure on the first positioning plate of the trim strip body, the installation stability between the trim strip body and the vehicle body can be enhanced without affecting the installation strength between the trim strip body and the vehicle body, thus reducing abnormal noise to a certain extent. If drivers and passengers expect a better driving experience, they do not need to replace the high-performance sound-absorbing cotton; they can choose ordinary sound-absorbing cotton, thus providing an extra layer of protection for the noise reduction of the vehicle body. The problem of abnormal noise in the vehicle can be addressed by combining the flexible first positioning plate of this application with ordinary sound-absorbing cotton, which reduces the cost of noise reduction and improves the noise reduction effect to a certain extent.

[0016] When the second positioning plate slides in the transverse through groove, the guide block in the transverse through groove also slides in the first guide groove of the second positioning plate, thereby improving the stability of the fit between the second positioning plate and the transverse through groove, and also enhancing the fit strength between the two. This also allows the second positioning plate to move smoothly in the predetermined direction when pushed by the extrusion block, reducing offset, thereby improving the accuracy of the first positioning plate installation process on the vehicle body.

[0017] When the second positioning plate slides in the transverse through groove, the first guide groove on the second positioning plate drives the guide rod to slide in the guide hole of the guide block. The first spring is compressed when the second positioning plate is pushed by the extrusion block, generating elastic restoring force, which pushes the second positioning plate to move the buffer outward and fit against the car mounting surface, enhancing the firmness of the trim strip body after installation.

Detailed Implementation

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] Please see Figure 1-7 As shown, this embodiment provides an automotive trim strip with an installation structure, including a trim strip body 1 and a plurality of first positioning plates 2 fixed on the trim strip body 1;

[0032] The first positioning plate 2 has a transverse through groove 202 and a vertical groove 219 connected to the transverse through groove 202. The transverse through groove 202 is provided with a first guide block 204 on both sides. The first guide block 204 is elastically fitted with a second positioning plate 208. The two second positioning plates 208 are provided with a buffer 209 on their opposite outer sides. The buffer 209 is made of rubber. The two second positioning plates 208 are provided with a first chamfer 211 on their opposite inner sides.

[0033] An extrusion block 212 is elastically fitted inside the vertical groove 219. The inclined surface of the first chamfer 211 faces the extrusion block 212. A positioning post 216 is adjustablely installed at the bottom of the extrusion block 212.

[0034] When the trim body 1 needs to be installed on the vehicle body, first press the trim body 1 downwards. When the positioning post 216 contacts the vehicle body, the extrusion block 212 is pushed upwards in the vertical groove 219 by the action of the vehicle body. The extrusion block 212 moves the two second positioning plates 208 towards the two ends of the transverse through groove 202 through the first chamfer 211. At this time, the second positioning plate 208 slides along the first guide block 204 until the buffer 209 on the outside of the second positioning plate 208 fits against the mounting surface of the vehicle body, reducing the installation gap and thus improving the stability of the car trim in the installation state on the vehicle body.

[0035] By designing a flexible mounting structure on the first positioning plate 2 on the trim strip body 1, the installation stability between the trim strip body 1 and the vehicle body can be enhanced without affecting the installation strength between the trim strip body 1 and the vehicle body, thus reducing abnormal noise to a certain extent. If drivers and passengers expect a better driving experience, they do not need to replace the high-performance sound-absorbing cotton; ordinary sound-absorbing cotton can be used instead. This provides an extra layer of protection for noise reduction in the vehicle body. The combination of the flexible first positioning plate 2 and ordinary sound-absorbing cotton in this application can be used to address vehicle abnormal noise issues, reducing noise reduction costs and improving noise reduction effectiveness to a certain extent.

[0036] In this embodiment, the second positioning plate 208 has a first guide groove 210, and a first guide block 204 is located in the first guide groove 210. The first guide block 204 has a guide hole 205, and a guide rod 206 is slidably fitted in the guide hole 205. When the second positioning plate 208 slides in the transverse through groove 202, the first guide block 204 in the transverse through groove 202 also slides in the first guide groove 210 of the second positioning plate 208, thereby improving the stability of the fit between the second positioning plate 208 and the transverse through groove 202, and also enhancing the fit strength between the two. This also allows the second positioning plate 208 to move smoothly in a predetermined direction when pushed by the pressing block 212, reducing offset, thereby improving the accuracy of the installation process of the first positioning plate 2 on the vehicle body.

[0037] In this embodiment, a first spring 207 is sleeved on a section of the guide rod 206 near the extrusion block 212. When the second positioning plate 208 slides in the transverse through groove 202, the first guide groove 210 on the second positioning plate 208 drives the guide rod 206 to slide in the guide hole 205 of the first guide block 204. The first spring 207 is compressed when the second positioning plate 208 is pushed by the extrusion block 212, generating an elastic restoring force, which pushes the second positioning plate 208 to move the buffer 209 outward and fit against the car mounting surface, enhancing the stability and elasticity of the trim body 1 after installation.

[0038] In this embodiment, the extrusion block 212 has a threaded hole 215 at its bottom, and the positioning post 216 has an external thread 217 that engages with the threaded hole 215. The external thread 217 of the positioning post 216 and the threaded hole 215 of the extrusion block 212 are threaded together, allowing for alignment during assembly through rotation. This fixes both in their axial and radial positions, reducing relative displacement. For example, in mechanical components, this structure allows the extrusion block 212 to be fixed in a designated position, and the position of the positioning post 216 can be flexibly adjusted during assembly. The distance between the extrusion block 212 and the vehicle body can be adjusted, and the position of the extrusion block 212 can be adjusted according to the specifications of the vehicle body mounting slot. Furthermore, when a component is damaged, it is easy to replace either the positioning post 216 or the extrusion block 212 individually, reducing maintenance costs.

[0039] In this embodiment, the vertical groove 219 has second guide grooves 203 on both sides, which are connected to the transverse through groove 202. The extrusion block 212 has second guide blocks 213 fixed on both sides, which slide in cooperation with the second guide grooves 203. When the extrusion block 212 moves at the junction of the transverse through groove 202 and the vertical groove 19, the second guide blocks 213 on the extrusion block 212 slide in the second guide grooves 203 of the vertical groove 219. The movement of the extrusion block 212 is limited to the trajectory of the second guide grooves 203, so that it moves in a straight line in a specific direction, reducing deviation or shaking. For example, when the extrusion block 212 moves, if the second guide block 213 and the second guide groove 203 have a high degree of cooperation, the extrusion block 212 can move vertically, reducing the uneven force caused by tilting, and making the thrust act evenly on the inclined surface of the first chamfer 211 of the second positioning plate 208, thereby enhancing the reliability of the pushing process.

[0040] In this embodiment, a second spring 214 is fixed on the second guide block 213, and the second spring 214 is located within the second guide groove 203. When the pressing block 212 moves at the junction of the transverse through groove 202 and the vertical groove 19, the second guide block 213 on the pressing block 212 slides within the second guide groove 203 of the vertical groove 219. The second spring 214 is compressed when the pressing block 212 is pushed downward by the second positioning plate 208. When the external force is removed, the elastic restoring force of the second spring 214 helps the pressing block 212 to return to its original position, ensuring that the installation structure maintains good elastic performance during use. The second guide groove 203 provides a movement track for the second guide block 213 or the second spring 214, while limiting its radial displacement.

[0041] In this embodiment, both sides of the contact point between the extrusion block 212 and the first chamfer 211 are provided with a second chamfer. The second chamfer increases the contact area, distributes the force evenly on the inclined surface, and improves the fatigue resistance of the structure. If the contact point is a right-angle edge, it is easy to cause jamming or damage due to edge collision during assembly. The inclined surface design of the first chamfer 211 can alleviate the impact at the moment of contact and make the parts fit more smoothly.

[0042] In this embodiment, the trim body 1 is fixed with multiple support arms 5, multiple rubber balls 4, and multiple guide plates 3. The support arms 5 have a first positioning hole 6 and a second positioning hole 7, with the second positioning hole 7 located above the first positioning hole 6. The first positioning plate 2 has multiple positioning holes 9 and a cover plate 8 is mounted on it. One side of the cover plate 8 has multiple positioning pins that engage with the positioning holes 9. When the trim body 1 contacts the first positioning plate 2 or other components, the elastic deformation of the rubber balls 4 can absorb vibration energy, reducing noise, wear, or structural damage caused by collisions. For example, in vehicle interiors, this design can reduce abnormal noises during driving. Simultaneously, the flexibility of the rubber balls 4 allows the trim body 1 to be finely adjusted within a small range, compensating for component processing errors or assembly tolerances, and improving structural compatibility. The support arms 5 can be fixed to the vehicle body via bolts or pins through the first positioning holes 6 and the second positioning holes 7. In scenarios requiring waterproofing or dustproofing, a sealing strip can be installed between the cover plate 8 and the first positioning plate 2 to enhance protective performance.

[0043] During installation:

[0044] First, insert the guide rod 206 into the guide hole 205 of the first guide block 204, put the first spring 207 on the section of the guide rod 206 near the extrusion block 212, and place the assembled first spring 207, guide rod 206 and first guide block 204 in the first guide groove 210 of the second positioning plate 208.

[0045] Screw the external thread 217 at the top of the positioning pin 216 into the threaded hole 215 at the bottom of the extrusion block 212. Place the extrusion block 212 at the connection between the transverse through groove 202 and the vertical groove 19. Then slide the extrusion block 212 downward. The extrusion block 212 drives the second guide block 213 and the second spring 214 into the second guide groove 203.

[0046] Then press down the extrusion block 212 and place the two second positioning plates 208 into the transverse through groove 202. During the process, the first guide block 204 is inserted into the preset slot of the first positioning plate 2. Then release the extrusion block 212. The extrusion block 212 rebounds under the elastic action of the second spring 214. At this time, the second chamfer of the first guide block 204 contacts the first chamfer 211 of the second positioning plate 208.

[0047] After assembly, the cover plate 8 is positioned on the first positioning plate 2 using the positioning pin and positioning hole 9.

[0048] When the trim body 1 needs to be installed on the vehicle body, when the positioning post 216 contacts the vehicle body, the pressing block 212 is pushed to slide upward in the vertical groove 219 under the action of the vehicle body. The second guide block 213 of the pressing block 212 slides upward in the second guide groove 203 and releases the restriction on the second spring 214. The second chamfer of the pressing block 212 moves the two second positioning plates 208 towards the two ends of the transverse through groove 202 through the first chamfer 211. At this time, the second positioning plate 208 slides along the first guide block 204. The first guide groove 210 of the second positioning plate 208 drives the guide rod 206 to slide in the guide hole 205 and compress the first spring 207 until the buffer 209 on the outside of the second positioning plate 208 is attached to the buckle 11 of the mounting seat 10 on the vehicle body, reducing the gap and thus improving the stability of the trim body 1 in the vehicle body installation state.
