Description

Technical Field

[0001] This utility model relates to the field of motorcycles, specifically to a front panel structure. Background Technology

[0002] The front panel of a motorcycle is a crucial component of its front appearance and structure. As a cover over the front of the motorcycle, it effectively shields and protects internal components such as the frame head tube, steering mechanism, wiring harness, and instrument panel bracket, preventing damage from mud, dust, and external impacts, thus affecting the overall protective performance of the motorcycle. Simultaneously, the front panel is also a vital exterior component, and its design has a decisive influence on the motorcycle's overall visual appeal and brand recognition.

[0003] Currently, motorcycle front panels are typically made of engineering plastics and produced through injection molding using complex molds. In terms of design, the front panel body is usually a large, complex, thin-walled shell structure, and its fixing method generally relies on designing numerous mounting points on the inner side of the front panel body. To match the numerous mounting points on the inner side of the front panel, a large number of mounting bases need to be machined on the frame or subframe, significantly increasing the complexity and cost of the vehicle body manufacturing process. A motorcycle panel plastic part with publication number CN218858601U discloses a front panel mounted on the vehicle body via a mounting frame. Locking elements are evenly spaced and connected through the front panel, and the locking elements on the front panel are connected to slots, which are correspondingly formed on the vehicle body.

[0004] The aforementioned utility model uses a mounting frame to fix the front panel. Because the front panel is large, numerous mounting positions need to be machined on the motorcycle body. However, the structure of the front of the motorcycle body is complex, and the mold parting surface design of the front panel is also complex, requiring a complex mold structure, which significantly impacts precision errors. Furthermore, since the positions of the mounting points and the mounting bases need to be precisely matched, high demands are placed on the injection molding precision of the front panel, the positional precision of each mounting point on the front panel, and the positional precision of the corresponding mounting seats on the motorcycle body. Errors in any of these precision aspects will significantly affect the subsequent installation of the front panel, leading to abnormal assembly or abnormal noises. Utility Model Content

[0005] The present invention aims to provide a front panel structure to solve the problem that the large size of existing front panels leads to significant accuracy errors that affect installation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The front panel structure includes a front panel body and a lower decorative panel. The upper part of the front panel body is provided with an upper decorative panel mounting area, and the upper part of the lower decorative panel is provided with a front panel mounting area. The lower part of the front panel body is connected to the front panel mounting area through multiple snap-fit ​​components. The front panel mounting area has multiple slots that cooperate with the snap-fit ​​components. The front panel mounting area has multiple lower decorative panel positioning holes. The back of the front panel body has multiple lower decorative panel positioning posts that cooperate with the lower decorative panel positioning holes. The lower decorative panel has multiple mounting holes.

[0008] The principles and advantages of this scheme are:

[0009] 1. This technology utilizes the front panel body, upper decorative panel and lower decorative panel to form the front panel body structure of the motorcycle. The upper decorative panel is installed in front of the front panel body, and the lower part of the back of the front panel body is connected to the lower decorative panel. The combination of the three parts forms the front panel body structure, which can better fit the streamlined appearance of the motorcycle, making the front of the motorcycle more beautiful and smooth, and better meeting the needs of sports motorcycles.

[0010] 2. The large and complex curved front panel structure is improved by combining an upper decorative panel, the front panel body, and a lower decorative panel. The smaller lower decorative panel is first installed on the vehicle body, and then the front panel body is fixed to it. Compared to directly installing the large front panel body onto the vehicle body, this reduces the number of mounting brackets on the vehicle body. Furthermore, dividing the front panel body structure into upper, lower, and upper decorative panels greatly simplifies the design of the injection molding parting surface, allowing for higher precision in both installation and manufacturing.

[0011] 3. The lower decorative panel not only assists in the installation of the front panel body, but also enhances the aesthetics and improves the smoothness of the front of the motorcycle.

[0012] 4. The front panel body is fixed using a snap-fit ​​assembly, which consists of a support column and snap-fits. The support column is integrally molded onto the front panel body, while the snap-fits are manufactured separately and assembled before installation, with the snap-fits engaging the support column. The support column structure is relatively simple and not difficult to manufacture, requiring only grooving. The snap-fit ​​structure is more complex and is manufactured separately to ensure precision in all parts of the snap-fit.

[0013] 5. The lower decorative panel is fixed to the vehicle body with bolts, and then the front panel body is installed on the lower decorative panel. This ensures the secure installation of the front panel body structure. At the same time, the front panel body can cover the bolts on the lower decorative panel, ensuring the aesthetics and smoothness of the front of the motorcycle.

[0014] 6. The latching components on the back of the front panel are concentrated at the bottom. This centralized design facilitates easy handling by operators during installation and disassembly, improving the efficiency of installation and disassembly.

[0015] Preferably, as an improvement, the latching assembly includes a support post and a latch, the support post being integrally formed on the back of the front panel body, and the latch being mounted on the support post.

[0016] Technical benefits: This solution adopts the above configuration, dividing the buckle assembly into two parts: the support column and the buckle. The support column has a relatively simple structure and is manufactured in one piece, while the buckle has a relatively complex structure and is designed and manufactured separately. This simplifies the molding of the front panel and makes it easier to control the quality and precision of the buckle.

[0017] Preferably, as an improvement, the support column includes a fixed plate and support plates fixed to both sides of the fixed plate. The two support plates are arranged in parallel, and the fixed plate is perpendicular to the two support plates. The two ends of the fixed plate are fixedly connected to the two support plates respectively, and the fixed plate is arranged perpendicular to the two support plates. The free end of the fixed plate is provided with a fixed plate guide slope. The fixed plate is provided with an upper positioning groove and a lower positioning groove. The upper positioning groove is close to the free end of the fixed plate, and the axial height of the lower positioning groove is greater than the axial height of the upper positioning groove.

[0018] Technical Effects: This solution employs the above-mentioned configuration, achieving hierarchical positioning through upper and lower positioning slots. The upper positioning slot is used during snap-fit ​​installation, where the snap-fit's positioning block inserts into it, forming a mechanical interlock to ensure the snap-fit's stability on the support column. The lower positioning slot is used during the installation of the front panel body, where the snap-fit's elastic arms retract inwards. The larger axial height of the lower positioning slot provides sufficient elastic deformation space for the two elastic arms to retract inwards, facilitating the installation of the front panel body. Furthermore, the larger axial height of the lower positioning slot improves the fault tolerance rate and reduces the precision requirements during snap-fit ​​manufacturing, allowing the snap-fit ​​to be successfully installed on the support column within a certain error range.

[0019] Preferably, as an improvement, the outer side of the support plate is provided with a support plate reinforcing rib, and the lower end of the support plate reinforcing rib is connected to the front panel body.

[0020] Technical effect: The above-mentioned configuration strengthens the support plate structure. The reinforcing ribs of the support plate provide bending resistance, significantly reduce the deformation at the root of the support plate, ensure the stability of the entire support column, and ensure the accuracy and stability of the buckle installation position.

[0021] Preferably, as an improvement, the buckle has a symmetrical structure, including a mounting block and elastic arms disposed on both sides of the mounting block. The lower end of the mounting block extends downward to form an extension, and a deformation cavity is formed between the extension and the elastic arm on the same side. A thin-walled area is provided on the elastic arm, which corresponds to the deformation cavity. The mounting block has a mounting groove along the axis of symmetry, and the bottom of the mounting groove penetrates the mounting block. Positioning blocks are provided at the bottom of the groove walls on both sides of the mounting groove. A mounting block guide slope is provided at the bottom of the mounting block. The mounting block guide slope is inclined downward and outward from the positioning block towards the extension. An elastic arm guide slope is provided on the outer side of the elastic arm, and a positioning protrusion is provided at the bottom of the inner side of the elastic arm. The positioning protrusion is located on both sides of the lower positioning groove.

[0022] Technical Effects: This solution employs the above-mentioned configuration, featuring a thin-walled area on the elastic arm. This increases the elastic potential energy of the elastic arm, significantly reducing the force required for bending, making it easier for the buckle to engage with the support column. Furthermore, the deformation cavity provides ample space for the elastic arm to bend inward during engagement. The guide ramp of the mounting block cooperates with the guide ramp of the fixing plate to guide the buckle into the support column. The positioning block and positioning protrusion cooperate with the upper and lower positioning grooves, respectively, ensuring the installation stability of the buckle and the front panel.

[0023] Preferably, as an improvement, the height of the positioning block matches the axial height of the upper positioning groove.

[0024] Technical effect: The above-mentioned configuration in this solution ensures that after the positioning block is inserted into the upper positioning groove, the side wall of the positioning block can fit tightly with the groove wall of the upper positioning groove to form a mechanical lock and ensure the stability of the snap-fit ​​installation.

[0025] Preferably, as an improvement, the back of the front panel body is provided with multiple vehicle body positioning pillars.

[0026] Technical benefits: The above-mentioned setup facilitates the positioning of the front panel body during installation, ensuring the accuracy of the installation position of the front panel body when it is mounted on the vehicle body.

[0027] Preferably, as an improvement, a lower decorative panel reinforcing rib is provided between the front panel mounting area and the lower decorative panel.

[0028] Technical effect: This solution uses the above settings to strengthen the front panel mounting area, enhance the strength of the lower decorative panel, and reduce the risk of deformation and breakage of the decorative panel. Attached Figure Description

Detailed Implementation

[0037] The following detailed description illustrates the specific implementation method:

[0038] Example 1

[0039] This solution provides the front panel structure, as shown in the attached diagram. Figure 1-7 As shown:

[0040] The front panel structure includes a front panel body 1 and a lower decorative panel 2. The upper part of the front panel body 1 has an upper decorative panel mounting area 11 for mounting the upper decorative panel (not shown in the figure). The lower part of the front panel body 1 is connected to the upper part of the lower decorative panel 2, specifically, as shown... Figure 2 As shown, the upper part of the lower decorative panel 2 is provided with a front panel mounting area 21. The lower part of the front panel body 1 is connected to the front panel mounting area 21 through two buckle 4 components. The front panel mounting area 21 is provided with two slots 24 that cooperate with the buckle 4 components, and the slots 24 are provided with reinforcing ribs in the circumferential direction to strengthen the slots 24.

[0041] The front panel mounting area 21 has four lower trim panel positioning holes 22. The back of the front panel body 1 has four lower trim panel positioning posts 13 that mate with the lower trim panel positioning holes 22. The lower trim panel 2 has multiple mounting holes 23, including three sets located at the upper, middle, and lower parts of the lower trim panel 2. Bolts pass through the mounting holes 23 and the bolt holes on the vehicle body and are tightened to connect the lower trim panel 2 to the vehicle body. A lower trim panel reinforcing rib 26 connects the front panel mounting area 21 and the lower trim panel 2.

[0042] Preferably, the front panel body 1 has multiple body positioning posts 12 along the edge of the back side. The multiple body positioning posts 12 are connected to the positioning holes on the body to position the front panel body 1 and ensure that the front panel body 1 is installed in the accurate position on the body.

[0043] The latch 4 assembly includes a support column 3 and a latch 4 mounted on the support column 3, specifically, as follows: Figure 6 The support column 3 includes a fixing plate 32 and support plates 31 fixed to both sides of the fixing plate 32. The two support plates 31 are arranged in parallel and are integrally formed on the front panel body 1. The fixing plate 32 is integrally formed and connected between the two support plates 31, and is perpendicular to the two support plates 31. The free end of the fixing plate 32 is provided with a fixing plate guide slope 321. The fixing plate 32 has an upper positioning groove 322 and a lower positioning groove 323 from top to bottom, with the upper positioning groove 322 near the free end of the fixing plate 32. The outer side of the support plate 31 is provided with a support plate reinforcing rib 33, and the lower end of the support plate reinforcing rib 33 is bonded to or integrally formed with the front panel body 1; Figure 7 As shown, the buckle 4 has a symmetrical structure, including a mounting block 41 and elastic arms 42 disposed on both sides of the mounting block 41. The mounting block 41 has a mounting groove 411 along the axis of symmetry. The bottom of the mounting groove 411 passes through the mounting block 41. The mounting groove 411 is connected to the upper part of the fixing plate 32. Positioning blocks 412 are provided at the bottom of the groove walls on both sides of the mounting groove 411. The bottom of the mounting block 41 is provided with a mounting block guide slope 413. The outer side of the elastic arm 42 is provided with an elastic arm guide slope 421. The bottom of the inner side of the elastic arm 42 is provided with a positioning protrusion 422.

[0044] The support column 3 is integrally formed on the back of the front panel body 1, while the buckle 4 is manufactured separately. In actual use, the buckle 4 needs to be installed on the support column 3 to form a whole, which is then inserted into the slot 24 of the lower decorative panel 2 to quickly install the front panel body 1 onto the lower decorative panel 2. Specifically, during installation, the mounting groove 411 in the middle of the buckle 4 is aligned with the fixing plate 32 of the support column 3 and inserted. At this time, the guide slope of the mounting groove 411 at the bottom of the mounting groove 411 fits against the guide slope 321 of the fixing plate at the end of the fixing plate 32, guiding the groove wall of the mounting groove 411 of the support column 3 to open to both sides, allowing the mounting block 41 to smoothly engage with the fixing plate 32. After the mounting block 41 is fully engaged with the fixing plate 32, the positioning block 412 at the bottom of the mounting groove 411 is inserted into the upper positioning groove 322. At this time, the positioning protrusion 422 at the bottom of the elastic arm 42 is located on both sides of the lower positioning groove 323.

[0045] Preferably, the height of the positioning block 412 matches the height of the upper positioning groove 322, so that after the positioning block 412 is inserted into the upper positioning groove 322, the side wall of the positioning block 412 can fit tightly with the groove wall of the upper positioning groove 322 to form a mechanical lock and ensure the stability of the buckle 4 installation.

[0046] Preferably, the axial height of the lower positioning groove 323 is greater than the axial height of the upper positioning groove 322, so that when the front panel body 1 is installed, the positioning protrusion 422 can smoothly engage in the lower positioning groove 323. The larger axial height of the lower positioning groove 323 can improve the fault tolerance rate, reduce the precision requirements of the buckle 4, and ensure that the length of the elastic arm 42 can increase or decrease within a certain error range, and that the positioning protrusion 422 at its bottom can smoothly engage in the lower positioning groove 323.

[0047] In actual installation, the mounting holes 23 on the lower trim panel 2 are aligned with the bolt holes on the vehicle body. Bolts are then passed through the mounting holes 23 and the bolt holes in sequence and tightened. At this point, the lower trim panel 2 is fixed to the vehicle body. Before installing the front panel body 1, the clips 4 are installed on the support pillar 3. Then, the clips 4 are aligned with the slots 24, the lower trim panel positioning pins 13 on the back of the front panel body 1 are aligned with the lower trim panel positioning holes 22, and the vehicle body positioning pins 12 on the back of the front panel body 1 are aligned with the positioning holes on the vehicle body and inserted. The vehicle body positioning pins 12 will insert into the positioning holes on the vehicle body, and the lower trim panel positioning pins 13 will insert into the lower trim panel positioning holes 22, thus positioning the front panel body 1 and ensuring its installation position. During installation, since the elastic arm 42 of the buckle 4 has an elastic arm guide slope 421 on the outside, it can guide the two elastic arms 42 to retract inward to facilitate insertion into the slot 24. At this time, the positioning protrusion 422 is engaged in the lower positioning groove 323 for positioning, preventing the elastic arms 42 from moving when retracting. When the buckle 4 is fully inserted into the slot 24, the two elastic arms 42 return to their original position under the action of elasticity. The outer side of the elastic arm 42 is tightly engaged with the side wall of the slot 24 to form a mechanical lock, preventing the front panel body 1 from falling off.
