Description

Technical Field

[0001] The present application relates to the technical field of vehicle spare parts, and particularly relates to a decorative part assembly and a taillight. Background Art

[0002] The appearance surface of the taillight decorative part is defined as the body color paint. Usually, in order to ensure the appearance quality of the painted surface, no structure is allowed on its back. Therefore, the taillight decorative part must be divided into an inner plate and an outer plate. The inner plate is fastened to the lamp body by screws through the metal spring nuts installed on it. At the same time, the inner plate is fastened to the outer plate by a certain method. Then, the installation design of the taillight decorative part is how to install and fix the inner plate and the outer plate.

[0003] The usual method is to connect by screw posts - screws. Since screw posts - screws are commonly used installation structures in exterior plastic parts, and in order to ensure that there is no risk of sink marks on the surface where the screw posts are located, a snap seat is established between the screw posts and the appearance surface. This results in the need for a large installation space for this structure. There is insufficient space at this location in existing vehicle models, and there are significant appearance risks for the painted surface.

[0004] The second common method is to use a snap - fit installation structure, which is commonly found in bumper assemblies. However, this structure often cannot form a positioning function, and there are risks in both the snap - fit strength and durability at this location. This part is installed on the outer panel of the rear door and moves with the opening and closing of the rear door, and there is also a risk of being pressed or pulled off by the user. To overcome these risks, the number of snap - fits needs to be increased, which will lead to a large number of sliders added to the mold, reducing the feasibility of the mold process and significantly increasing the cost of the mold. This runs counter to the spirit of reducing costs through technology promoted in recent years, so it is not applicable.

[0005] In the newly designed vehicle models, due to aesthetics or automotive styling design, the space for the taillight decorative part is relatively narrow. Therefore, it is difficult to meet the design requirements by using the above - mentioned two normal - direction installation methods and performing root deburring treatment.

[0006] In summary, the installation structure in the normal direction cannot meet the structural size requirements of the taillight decorative part assembly of this vehicle model. Summary of the Invention

[0007] Aiming at the defects existing in the prior art, the purpose of the present application is to provide a decorative part assembly and a taillight, which can install the decorative part assembly on the taillight in a narrow operation space while ensuring the stability of the decorative part assembly.

[0008] To achieve the above - mentioned purpose, on the one hand, the technical solution adopted is:

[0009] The present application provides a decorative part assembly, including:

[0010] The decorative inner panel is provided with threaded holes in the middle for connecting with the tail lamp. At least one sliding slot is arranged on the edge of the decorative inner panel, and an installation notch is arranged on the edge of the decorative inner panel.

[0011] The decorative outer panel is provided with a plurality of first sliding slots matching the installation notches, and sliding buckles matching the sliding slots are arranged on the decorative outer panel.

[0012] When the decorative outer panel is installed on the decorative inner panel, the edges of the installation notch and the first sliding slot are inserted, and the sliding buckles are clamped in the sliding slots.

[0013] In some more preferred embodiments, the decorative inner panel includes:

[0014] A load-bearing convex plate;

[0015] An edge plate is arranged on the edge of the load-bearing convex plate. The installation notch is arranged on the outer edge of the edge plate, and the sliding slot is arranged on the edge plate.

[0016] In some more preferred embodiments, the edge plates on both sides of the decorative inner panel and the decorative outer panel in the installation direction protrude outward to form limiting bumps.

[0017] In some more preferred embodiments, the decorative inner panel further includes a reed fixedly installed on the load-bearing convex plate, and the threaded hole is opened on the reed.

[0018] A positioning hole is opened on the load-bearing convex plate, and the positioning hole and the threaded hole are coaxial.

[0019] In some more preferred embodiments, the decorative inner panel further includes:

[0020] A reinforcing rib group, which is composed of a plurality of reinforcing ribs with the length direction being the installation direction of the decorative outer panel. The reinforcing rib group is arranged on the edge plate, and each reinforcing rib partially extends out of the edge plate.

[0021] When the decorative outer panel is installed on the decorative inner panel, the end of each reinforcing rib in the reinforcing rib group abuts against the decorative outer panel.

[0022] In some more preferred embodiments, a limiting plate is further arranged on the decorative outer panel, and the extending direction of the limiting plate forms an acute angle with the plane where the decorative outer panel is located;

[0023] A slope matching the limiting plate is arranged at the end of the reinforcing rib;

[0024] When the installation of the decorative outer panel and the decorative inner panel is completed, the slope of the reinforcing rib cooperates with the limiting plate.

[0025] In some more preferred embodiments, the sliding slot includes:

[0026] A card slot hole, which is formed in the decorative inner panel;

[0027] A spring piece, which is installed in the slot hole and extends in a direction opposite to the installation direction of the decorative outer panel and the decorative inner panel;

[0028] When the decorative outer panel is installed on the decorative inner panel, the end of the spring piece abuts against the sliding buckle.

[0029] In some more preferred embodiments, a second sliding insert block is formed at the edge of the decorative inner panel in the direction opposite to the installation direction;

[0030] A second sliding slot matching the second sliding insert block is formed on the decorative outer panel.

[0031] The present application further provides a tail lamp, and a cavity for accommodating the foregoing decorative member is formed in the tail lamp;

[0032] A bolt for cooperating with the threaded hole is arranged at the bottom of the cavity.

[0033] In some more preferred embodiments, a pre-installed plug-in member is arranged on the decorative inner panel of the decorative member;

[0034] A plug-in hole cooperating with the pre-installed plug-in member is arranged at the bottom of the cavity.

[0035] The beneficial effects brought by the technical solution provided by the present application include:

[0036] The decorative member assembly and a tail lamp of the present application,

[0037] First, the decorative inner panel is installed on the cavity of the tail lamp. At this time, the interior of the decorative inner panel is open, with a large operating space, and the installation is very simple. Then, through the cooperation of the first sliding slot and the installation notch, only lateral sliding is required during installation. The first sliding slot is inserted from the installation notch and then inserted into the edge of the installation notch to complete the installation. At the same time, the left and right sliding is locked through the cooperation between the sliding buckle and the sliding slot, making use of the external space of the vehicle, improving the installation efficiency, and at the same time, there is no need for complicated correction and alignment processes, nor is it necessary to reserve space for observation for the above processes.

[0038] In the traditional normal connection, the contact surface near the installation position is very small, approximately point-to-point collision. On the other hand, the collision between the decorative outer panel and the decorative inner panel is the collision between the side wall of the installation notch and the inner wall of the sliding slot, which is a face-to-face collision, generating very little noise and eliminating the abnormal sound of the product.

[0051] In order to make the objectives, technical solutions and advantages of the present application more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0052] The present application provides an embodiment of a decorative part assembly, as Figure 1 shown, which includes a decorative inner panel 1 and a decorative outer panel 2. In this embodiment and subsequent embodiments, the insertion direction when the decorative outer panel 2 is assembled to the decorative inner panel 1 is referred to as the installation direction.

[0053] As Figure 2 、 Figure 3 and Figure 4 shown, the decorative inner panel 1 is mainly used to connect to the headlight body to provide an installation base. A threaded hole 15 for connecting to the taillight 3 is provided in the middle of the decorative inner panel 1. An installation notch 14 is provided at the edge of the decorative inner panel 1, and a sliding slot 16 is also provided on the decorative inner panel 1.

[0054] The decorative outer panel 2 mainly serves an external shielding effect. Generally, a plurality of first sliding slots 22 are provided on the decorative outer panel 2, and the shape can be seen in Figure 4 and Figure 5 . In some embodiments, in order to reduce weight, a lot of weight-reducing strips are opened on the surface of the first sliding slot 22 to form a structure similar to a grid. The main function of the first sliding slot 22 is to insert and cover the edge of the installation notch 14 until the installation notch 14 is sleeved, preventing the decorative outer panel 2 from moving in the vertical direction. The sliding buckle 21 is used to match the sliding slot 16. When the sliding buckle 21 is embedded in the sliding slot 16, the horizontal sliding of the decorative outer panel 2 is restricted.

[0055] The specific installation process is as follows:

[0056] First, align the first sliding slot 22 with the corresponding installation notch 14, and push the decorative outer panel 2 along the normal direction until the first sliding slot 22 extends into the installation notch 14. Then, slide the decorative outer panel 2 horizontally, in the Figure 4 shown direction is to slide to the right. At this time, the first sliding slot 22 covers the edge of the installation notch 14 until the sliding buckle 21 is embedded in the sliding slot 16, restricting the left and right sliding of the decorative outer panel 2. The process of the first sliding slot 22 extending into the installation notch 14 does not require observation. Workers can feel whether the installation is in place by hand, saving the observation space. On the other hand, workers can also make a preliminary alignment according to the shape of the decorative outer panel 2.

[0057] In this embodiment, the left - right sliding is locked through the cooperation between the sliding buckle 21 and the sliding slot 16, making use of the external space of the vehicle, improving the installation efficiency. At the same time, there is no need for complicated alignment and correction processes, nor is it necessary to reserve space for observation for the above - mentioned processes.

[0058] In some cases, the decorative inner panel 1 is in the shape of a whole flat plate or close to a flat plate. During the installation and debugging process, inappropriate force application is inevitable. At the same time, there will inevitably be bumps during the vehicle operation. The flat plate has poor torsional resistance, which is not conducive to the long - term use of the decorative part assembly. Therefore, in some preferred embodiments, the decorative inner panel 1 includes a load - bearing convex plate 11 and an edge plate 12.

[0059] Specifically, as Figure 4 and Figure 5 shown, the parts that generally do not need to be connected to the decorative outer panel 2 are all load - bearing convex plates 11. The load - bearing convex plate 11 can be referred to Figure 9 . The bottom is a cavity, so the strength of the whole structure is greatly improved. The edge of the load - bearing convex plate 11 is set as the edge plate 12. Specifically, the edge plate 12 is at the front and both sides in the installation direction. These three directions need to have a structural connection with the decorative outer panel 2. If it is set as the structure of the load - bearing convex plate 11, the connection structure needs to be heightened, which is very unfavorable to the strength of the connection structure. Therefore, through the setting of the edge plate 12, the connection structure between the decorative inner panel 1 and the decorative outer panel 2 is made as small as possible, improving the strength of the connection structure and extending the service life. In some other embodiments, as Figure 4 and Figure 5 shown, in order to reduce the overall weight, weight - reducing holes are also opened at unimportant positions of the load - bearing convex plate 11 to reduce the weight.

[0060] In some cases, the side of the edge plate 12 is straight and similar to the inner wall of the decorative outer panel 2. However, it is found in the actual R & D process that if the edge plate 12 is straight, then in the last stage of installation, part of the edge plate 12 will fit on the inner wall of the decorative outer panel 2, resulting in a sharp increase in the contact area between the two. The friction force is greatly increased, affecting the installation.

[0061] Therefore, in some preferred embodiments, the edge plates 12 on both sides in the installation direction protrude outward to form limit bumps 121. On the one hand, the limit bumps 121 can limit the up - and - down movement of the decorative outer panel 2. On the other hand, during the installation process, the contact area between the edge plate 12 and the decorative outer panel 2 is greatly reduced, so that the friction force is also correspondingly reduced, facilitating the installation of the decorative outer panel 2 by the worker. Specifically, there is one on each side of the installation notch 14 on each side.

[0062] In some embodiments, the threaded hole 15 is directly provided on the load-bearing convex plate 11. In order to effectively bear the load, the load-bearing convex plate 11 has relatively high strength and very poor elasticity. This makes the connection between the taillight 3 and the load-bearing convex plate a rigid connection, and the impacts caused by various bumps during vehicle driving cannot be dissipated and can only be transmitted to the decorative outer panel 2, resulting in noise generated by the collision between the decorative outer panel 2 and the taillight 3.

[0063] Therefore, in some preferred embodiments, the above-mentioned decorative inner panel 1 further includes a reed 13 fixedly installed on the load-bearing convex plate 11. The above-mentioned threaded hole 15 is opened on the reed 13, and only a positioning hole 111 with a smooth inner wall is provided on the load-bearing convex plate 11. Specifically, reference can be made to Figure 4 , Figure 7 and Figure 8 . Sometimes, in order to adapt to the specific structure of the taillight 3, a protruding part is provided on the load-bearing convex plate 11 so that the reed 13 can be as close to the taillight 3 as possible, facilitating installation. In this embodiment, it can be seen that a recessed structure is provided on the load-bearing convex plate 11, and the protruding part for bearing the reed 13 forms a protruding bridge similar to a bridge across this recessed structure. The side of the reed 13 is provided with a claw that can catch the side of this protruding bridge, and the recessed part is just used as a sliding channel for the installation of the reed 13. The positioning hole 111 is only used to limit the movement of the bolt 31, and only the reed 13 is directly connected to the bolt 31. In this way, various movements during vehicle driving will be dissipated by the reed 13 and will not be transmitted to each component, extending the service life.

[0064] In some embodiments, the edge plate 12 or the load-bearing convex plate 11 is directly used to abut against the inner wall of the decorative outer panel 2 in the installation direction. However, when using the edge plate 12 to abut, the edge plate 12 is easily bent under various impacts during driving and installation. When directly using the load-bearing convex plate, because the taillight 3 usually has a special shape design, the processing cost for the load-bearing convex plate to adapt to this shape is also very high.

[0065] Therefore, in some preferred embodiments, the above-mentioned decorative inner panel 1 further includes a reinforcing rib group 17. The reinforcing rib group 17 is composed of multiple reinforcing ribs with the length direction being the installation direction, and some of them extend out of the edge plate 12. Specifically, the lengths of the reinforcing ribs are different and need to be designed according to the abutting position. Specifically, reference can be made to Figure 5 , Figure 5 . Only the left edge plate 12 needs to abut against the decorative outer panel 2, and the upper and lower edge plates 12 do not have this requirement. Therefore, only multiple reinforcing ribs are equidistantly arranged on the left edge plate 12, and at the same time, the extended part of the reinforcing rib is adjusted to adapt to the shape of the decorative outer panel 2. The other end of the reinforcing rib is generally connected to the side of the load-bearing convex plate 11 to provide a stress point and enhance the anti-bending ability of the entire edge plate 12.

[0066] In some embodiments, for example Figure 4 , the installation notch 14 is set at a position far from the left end, and the end limiting effect on the decorative outer panel 2 is not good. After long-term use, the end of the decorative outer panel 2 is likely to warp, affecting the appearance and increasing the repair difficulty at the same time.

[0067] Therefore, in some preferred embodiments, a limiting plate 23 is further provided on the above-mentioned decorative outer panel 2. Refer to Figure 4 and Figure 9 . The limiting plate 23 is inclined and forms an acute angle with the bottom surface of the decorative outer panel 2. The opening direction of the acute angle faces the back of the installation direction. The end of each reinforcing rib is cut to form an inclined surface that matches the limiting plate 23. In this way, when the decorative outer panel 2 is inserted into the decorative inner panel 1, the side wall of the decorative outer panel 2 and the limiting plate 23 clamp the reinforcing rib from both sides, forming a V-shaped normal limiting device, which avoids the warping of the decorative outer panel 2 at this position. On the other hand, since there are often some structures on the taillight 3 that protrude, especially there are some protrusions such as reinforcing structures near the edge of the decorative outer panel 2, the limiting plate 23 is used to slightly push the abutting position of the reinforcing rib away, reserving a part of the space for the taillight 3 to use.

[0068] In some embodiments, the sliding card slot 16 is a square or circular slot directly opened on the edge plate 12. In this way, during the installation process, the worker needs to forcefully push the decorative outer panel 2 to install it, and the installation process is very inconvenient. In some cases, it will also cause deformation of the decorative inner panel 1.

[0069] Therefore, in some preferred embodiments, the above-mentioned sliding card slot 16 includes a card slot hole 161 and a spring piece 162. Specifically, the card slot hole 161 is a square hole opened on the decorative inner panel 1, and the spring piece 162 is a metal piece with strong elasticity, which extends from one side of the card slot hole 161, and the extending direction is opposite to the installation direction of the decorative outer panel 2. In this way, during the installation process, the spring piece 162 will be squeezed first, which will not cause damage to the decorative outer panel 2. At the same time, the worker can determine whether the sliding buckle 21 is aligned with the card slot hole 161 according to the resilience. When the decorative outer panel 2 slides in place, the sliding buckle 21 just breaks away from the spring piece 162. At this time, the spring piece 162 will rebound and make a relatively loud sound. The worker can determine that the installation is in place according to the resilience and the sound. At this time, the top of the spring piece 162 will abut against the sliding buckle 21, and the position of the sliding buckle 21 is limited by the top of the spring piece 162 and the side wall of the card slot hole 161.

[0070] In some embodiments, since the installation process requires the decorative outer panel 2 to be inserted into the decorative inner panel 1 first and then slid, there is a certain distance between the side of the decorative inner panel 1 away from the installation direction and the inner wall of the decorative outer panel 2. At the same time, no structure can be provided in this distance because the moving space of the decorative outer panel 2 needs to be avoided. Therefore, the side of the decorative outer panel 2 away from the installation direction and the decorative inner panel 1 cannot form an effective connection, and warping often occurs.

[0071] To solve this problem, in some preferred embodiments, reference can be made to Figure 7 and Figure 9 , a second sliding plug 18 is provided on the edge of the side of the decorative inner panel 1 away from the installation direction. The second sliding plug 18 is a two-segment bent structure, one segment extending towards the decorative outer panel 2 and the other segment extending towards the installation direction, and the two together form a structure similar to a hook. And a second sliding slot 24 is provided on the decorative outer panel 2. The shape of the second sliding slot 24 is similar to a "door" shape. Therefore, during the installation process, the second sliding plug 18 will be inserted into the second sliding slot 24 as the decorative outer panel 2 moves, so as to hook the second sliding slot 24 and prevent the decorative outer panel 2 on this side from warping.

[0072] The present application also provides an embodiment of a taillight 3 as shown in Figure 1 and Figure 2 . A cavity for installing the decorative part assembly is formed by the central downward depression of the taillight 3. The actually externally emitting part of the taillight 3 surrounds the decorative part assembly, forming a unique lighting effect. Bolts 31 for connecting to the decorative inner panel 1 are provided at the bottom of the cavity.

[0073] The main connection relationship between the decorative part assembly provided by the present application and the taillight 3 is the bolts 31. However, during the installation process, the bolts 31 have not been connected to the decorative part assembly, and no effective connection is formed between the decorative inner panel 1 and the taillight 3. This makes it necessary for two people, one inside and one outside, to install, or for the worker to hold the decorative inner panel 1 with one hand outside and drill under the vehicle to connect the bolts 31 to the decorative inner panel 1. Whichever method is used, it is very awkward and also reduces the installation efficiency.

[0074] Therefore, in some preferred embodiments, a pre-installed plug-in part 19 is provided on the above-mentioned decorative inner panel 1, and a plug-in hole matching the pre-installed plug-in part 19 is provided at the bottom of the cavity. Specifically, reference can be made to Figure 7 and Figure 9The pre-installed connector 19 is a spike-shaped structure, and its main body is a plane with a barb formed at the tip. In this way, during the installation process, the plane of the pre-installed connector 19 can be flush with the side of the plug hole, and then the decorative inner panel 1 can be pushed in, so that the pre-installed connector 19 is mounted in the main body of the taillight 3. In this way, the decorative inner panel 1 and the cavity are roughly aligned. The worker only needs to make a simple adjustment to enter the car body and tighten the bolt 31, so that the decorative inner panel 1 and the taillight 3 are effectively connected. The labor required for assembly is greatly reduced and production efficiency is improved.

[0075] Below Figures 1-9 The present application is described with reference to the specific embodiment shown. This embodiment has a decorative outer panel 2 and a decorative inner panel 1. The decorative inner panel 1 is composed of a load-bearing convex panel 11 and an edge panel 12. The cross section of the structure formed by the load-bearing convex panel 11 and the edge panel 12 is close to a "+" shape. The middle part of the decorative inner panel 1 is raised to form a raised bridge, and a spring 13 is installed on the raised bridge. The side of the spring 13 is provided with a claw to grasp the raised bridge. A threaded hole 15 is provided in the center of the spring 13, and a positioning hole 111 is provided at a corresponding position on the raised bridge. The positioning hole 111 and the threaded hole 15 are coaxial.

[0076] There are three edge plates 12, one in front of the installation direction and the other on both sides of the installation direction. Five reinforcing ribs are arranged at equal intervals on the edge plate 12 in front of the installation direction. Figure 5 In the direction shown, the upper edge plate 12 has a mounting notch 14 and two limiting bosses on its side, and a convex rib for strengthening is arranged next to the mounting notch 14. At the same time, a sliding slot 16 is provided at the portion of the edge plate 12 close to the mounting direction. The sliding slot 16 is a rectangular slot, and a spring piece 162 is arranged in the sliding slot 16. The combined shape of the sliding slot 16 and the spring piece 162 is similar to a U-shaped structure. The lower edge plate 12 is inclined, and also has a mounting notch 14 and two limiting bosses. A convex rib for strengthening the structure is arranged next to the mounting notch 14.

[0077] by Figure 5 In the direction shown, the right side of the spring 13 is the pre-installed connector 19, the bottom surface of the pre-installed connector 19 is a plane, the top is folded, and a downward hook-shaped structure is formed, which can be used to hook the corresponding structure on the taillight 3 body, and a reinforcing structure is provided on the back of the pre-installed connector 19. The right side of the pre-installed connector 19 is the second sliding block 18, the structure of the second sliding block 18 is similar to the sliding card slot 16, both forming a nearly rectangular cavity, and one side extends out in two sections, one section facing the decorative outer panel 2, and the other section facing the installation direction, forming a hook-shaped structure.

[0078] Decorative outer panel 2 can be found in Figure 6 andFigure 9 , the overall shape is close to a flat shape with a slight arc. The specific shape needs to be determined according to the vehicle model design. There is a side wall surrounding the decorative outer panel 2. And Figure 6 As shown, there is a first sliding slot 22 on each of the upper and lower sides of the decorative outer panel 2. Generally, the shape of the first sliding slot 22 is similar to that of the mounting notch 14 to ensure that only as little material as possible is removed to improve the strength of the edge plate 12. The first sliding slot 22 is provided with a plurality of strip-shaped holes to form a grid structure to reduce the weight. A limiting plate 23 is provided on the left side of the decorative outer panel 2. The limiting plate 23 is mainly used to limit the warping of the left side of the decorative outer panel 2 and at the same time to avoid a protruding structure extending from the taillight 3. And a second sliding slot 24 corresponding to the second sliding block 18 is provided on the right side. The sliding buckle 21 is arranged at the upper left corner and corresponds to the position of the sliding groove 16. Specifically, the shape of the sliding buckle 21 is similar to a U shape.

[0079] And the structure of the taillight 3 can be referred to Figure 1 , Figure 2 and Figure 3 , among which Figure 3 is taken as an example. The body of the taillight 3 forms a cavity with a stepped structure, and the edge of the decorative outer panel 2 is adapted to the cavity. At the same time, the bolt 31 extends from the bottom of the cavity and is connected to the reed 13 on the decorative inner panel 1.

[0080] And the specific installation process is as follows:

[0081] S1. Insert the pre-installed connector 19 into the connector on the taillight 3, and then push the decorative inner panel 1 until the tip of the pre-installed connector 19 hooks the adapted structure.

[0082] S2. Adjust the position of the decorative inner panel 1 so that the threaded hole 15, the positioning hole 111 and the hole at the bottom of the cavity are roughly aligned.

[0083] S3. Tighten the bolt 31 in the vehicle body so that the bolt 31 is connected to the threaded hole 15.

[0084] S4. After confirming that the decorative inner panel 1 is firmly installed, roughly align the decorative outer panel 2 with the edge of the cavity.

[0085] S5. Push the decorative outer panel 2 so that each first sliding slot 22 extends into the corresponding mounting notch 14, and at the same time the sliding buckle 21 abuts against the elastic piece 162. Slide the decorative outer panel 2 and confirm that each first sliding slot 22 is accurately inserted into the corresponding mounting socket, and then slide the decorative outer panel 2 to the end.

[0086] S6. After feeling the elastic piece 162 rebound, confirm that the installation is completed.

[0087] At this time, Figure 4As shown, the upper and lower sides of the decorative outer panel 2 are restricted in movement by the limiting bosses, and the left and right sides are restricted in movement by the sliding buckles 21 and the sliding grooves 16. At the same time, the left side cannot warp due to the restriction of the limiting plate 23, and the right side cannot warp due to the restriction of the second sliding insert 18 and the second sliding slot 24, so the overall installation is firm.
