Description

Technical Field

[0001] The invention relates to the technical field of automobile taillights, and in particular to an automobile taillight with a side decorative plate quick-installation function. Background Art

[0002] At present, the automobile taillight is a set of lamps installed at the rear of the car, mainly used to improve the visibility of the vehicle at night or in low visibility conditions to ensure driving safety. The automobile taillight side panel is part of the taillight system. It usually refers to the part of the taillight assembly located on the side of the vehicle. This part can be part of the taillight or a separate side light. The main functions of the side panel include: protecting the taillight from impact and damage, coordinating with the overall design of the vehicle, enhancing the appearance of the vehicle, serving as a fixing and supporting structure for the taillight, and ensuring the stability of the taillight. In some designs, the taillight side panel may also help improve the aerodynamic performance of the vehicle. The design and material of the taillight side panel need to take into account durability, weather resistance, and coordination with the overall design of the vehicle. In some models, the taillight side panel may also integrate the functions of turn signals, reverse lights, or other auxiliary lights.

[0003] However, the current automobile taillight side panels have the following defects: the existing decorative panel installation method generally adopts the method of engaging the slots with the ribs of the lamp housing, and then locking and fixing them with at least two screws. For example, the utility model patent with application number CN201520370656.2, application date 2015.06.02, and titled "A combination decorative panel for automobile" clearly states that the daytime running lights are screwed through the mounting feet and locked on the mounting posts of the decorative panel; the front fog lights are screwed through the mounting holes 7 on the mounting panel 6 and locked in the mounting posts 5 of the decorative panel 3 to complete the assembly of the front fog lights and the decorative panel 3.

[0004] Although this method is structurally strong and the operation process is relatively simple and intuitive, it has some disadvantages. First, the use of two or more screws increases material costs, especially in large-scale production, this cost increase will become more significant. Second, due to the single installation method and lack of flexibility, it may also increase the time cost of the assembly process. Summary of the invention

[0005] The present invention aims to solve the problems existing in the above-mentioned prior art and provides a car taillight with a side decorative panel quick-installation function. First, the decorative panel is placed close to the vehicle body, and a pre-positioning plate is used to limit the movement of the decorative panel in the Z direction. Then, the decorative panel slides along the X direction, so that the guide strip is clamped into the limiting piece, thereby limiting the movement of the decorative panel in the Y direction. As the decorative panel continues to slide, the first elastic clamping component and the second elastic clamping component are respectively clamped on the Z-direction positioning column and the Y-direction positioning column, thereby limiting the movement of the decorative panel in the X direction.

[0006] The present invention solves the technical problem by adopting a technical solution: The automobile taillight with a side decorative panel quick-installation function comprises a lamp housing and a decorative panel fixed outside the lamp housing, the decorative panel comprises an outer panel, an upper panel located above the outer panel, a lower panel located below the outer panel, and a rear panel located behind the outer panel, the outer panel, the upper panel, the lower panel, and the rear panel are integrally formed and semi-enclosed outside the lamp housing; A pair of pre-positioning plates are installed on the inner walls of the upper side plate and the lower side plate, and the pre-positioning plates extend in depth along the Y direction. When the outer side plate is close to the lamp housing, the pre-positioning plates press against the upper and lower sides of the lamp housing. A stopper extending in the X direction and opening is provided on the inner wall of the outer plate, and a guide bar matching the stopper is provided on the lamp housing. The guide bar and the stopper move in the X direction, and the cooperation between the pre-positioning plate and the lamp housing clamps the stopper on the guide bar, and simultaneously positions the decorative plate in the Y direction; A Z-direction positioning column is provided on the rear section of the inner wall of the outer plate, and a first elastic clamping component is provided on the lamp housing for the Z-direction positioning column to be laterally clamped, and the Z-direction positioning column and the first elastic clamping component are fixedly matched to position the decorative plate in the X direction; The upper side plate or the lower side plate is provided with a Y-direction positioning column, and the lamp housing is provided with a second elastic clamping component for the Y-direction positioning column to be laterally clamped. The Y-direction positioning column cooperates with the second elastic clamping component to position the decorative plate in the X direction.

[0007] For further improvement, a pair of pre-positioning plates are in the form of thin sheets, and an arc-shaped guide edge is provided at one end of the pre-positioning plate in contact with the lamp housing. The arc-shaped guide edge guides the lamp housing into between the pair of pre-positioning plates, and the pair of pre-positioning plates limit the movement of the lamp housing in the Z direction.

[0008] To be further improved, the limiting component includes a Y-direction limiting plate with a spacing between the Y-direction limiting plate and the outer plate, a connecting plate arranged at the bottom end of the Y-direction limiting plate and fixedly connecting the Y-direction limiting plate and the outer plate, the Y-direction limiting plate and the connecting plate are combined to form an L-shape, the Y-direction limiting plate is the long side of the L-shape, and the connecting plate is the short side of the L-shape.

[0009] For further improvement, there are two limit members and the angle between the two limit members is less than 180 degrees, and when the two limit members are clamped on the guide strip, the movement of the decorative plate in the Z direction is limited.

[0010] For further improvement, the guide bar is arranged as a flanged long strip arranged along the edge of the lamp housing, the guide bar moves along the X direction into between the Y direction limiting plate and the outer plate, and the decorative plate is limited by the Y direction limiting plate in the Y direction.

[0011] For further improvement, the Z-direction positioning column is fixed on the outer plate and is provided with an outer folded edge at the top to limit the movement of the first elastic clamping component in the Y direction. When the first elastic clamping component is clamped on the Z-direction positioning column, it is located between the outer folded edge and the outer plate.

[0012] To be further improved, the first elastic clamping component includes a pair of elastic strips fixed on the lamp housing and with a spacing smaller than the diameter of the Z-direction positioning column, an arc clamping groove arranged on the inner side of the pair of elastic strips and capable of cooperating with the outer side of the Z-direction positioning column, and an expansion opening arranged on the inner side of the pair of elastic strips and connected to the arc clamping groove. The Z-direction positioning column opens the pair of elastic strips through the expansion opening and enters the arc clamping groove. When the arc clamping groove cooperates with the Z-direction positioning column, it limits the movement of the decorative panel in the Z and X directions.

[0013] Further improvement, the Y-direction positioning column is fixed on the upper side plate or the lower side plate, the Y-direction positioning column is at a 90-degree angle to the Z-direction positioning column, the second elastic clamping component has the same structure as the first elastic clamping component, and the cooperation between the second elastic clamping component and the Y-direction positioning column limits the movement of the decorative panel in the Y and X directions.

[0014] For further improvement, several pairs of vertical plates are formed on the outer plate, an X-direction channel is formed between the vertical plates, and a sliding vertical bar that cooperates with the X-direction channel is installed on the lamp housing. The vertical bar guides the first elastic clamping component and the second elastic clamping component to be respectively clamped on the Z-direction positioning column and the Y-direction positioning column by sliding in the X-direction channel.

[0015] Further improvement, the X-direction channel includes a V-shaped wide mouth portion for roughly guiding the vertical bars and a narrow mouth portion for accurately guiding the vertical bars, the spacing of the V-shaped wide mouth portion is greater than the width of the vertical bars, and the spacing of the narrow mouth portion matches the width of the vertical bars.

[0016] The beneficial effect of the present invention is that in the present invention, the design of the end of the decorative plate will match the corresponding shape of the lamp housing. This design ensures that in actual operation, the decorative plate can be quickly and accurately installed by gently pushing it vertically behind the lamp housing. As the decorative plate is pushed in smoothly, there will be three crisp "click" sounds, indicating that the decorative plate has been fully installed in place. This sound feedback mechanism greatly simplifies the installation process, and the operator can be sure of the accuracy and completeness of the installation without a detailed inspection with the naked eye. The entire installation process therefore becomes extremely simple and quick. At the same time, since the traditional screw locking step is omitted, it not only improves the installation efficiency, but also effectively reduces the manufacturing and maintenance costs. This innovative installation method not only improves the convenience of operation, but also provides a new solution for the rapid assembly and maintenance of lamps.

DETAILED DESCRIPTION

[0019] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0020] See attached Figure 1 to Figure 8: In this embodiment, the automobile taillight with the side decorative panel quick-installation function is mainly composed of two main parts: a lamp housing 1 and a decorative panel 2 fixed outside the lamp housing 1. The lamp housing 1 is the basic structure of the taillight, responsible for carrying the light source and electronic components, and the decorative panel 2 is a decorative component installed outside the lamp housing 1, which serves to enhance the overall beauty and coordination of the vehicle appearance. The decorative panel 2 is composed of four parts, including an outer panel 2-1, an upper side panel 2-2 located above the outer panel 2-1, a lower side panel 2-3 located below the outer panel 2-1, The rear side panel 2-4 is located behind the outer side panel 2-1. The outer side panel 2-1, the upper side panel 2-2, the lower side panel 2-3, and the rear side panel 2-4 are integrally formed and semi-enclosed outside the lamp housing 1. The integrally formed design ensures the structural strength and appearance consistency of the decorative panel 2, which not only improves production efficiency, but also reduces possible errors and defects during the assembly process, and can be quickly and conveniently installed or replaced, greatly simplifying the maintenance and repair process of the taillight. The semi-enclosed design not only enhances the aesthetics of the taillight, but also makes the taillight more sturdy and durable.

[0021] A pair of relatively arranged pre-positioning plates 3 are installed on the inner walls of the upper side plate 2-2 and the lower side plate 2-3. The main function of the pre-positioning plates 3 is to quickly align and position the decorative plate 2 with the lamp housing 1. The pre-positioning plates 3 are one of the key components for realizing the rapid installation of the decorative plate 2. The pre-positioning plates 3 extend in depth along the Y direction. When the outer side plate 2-1 is close to the lamp housing 1, the pre-positioning plates 3 press against the upper and lower sides of the lamp housing 1. At this time, the pre-positioning plates 3 limit the movement of the decorative plate 2 in the Z direction, thereby realizing the preliminary positioning of the decorative plate 2. The pre-positioning plates 3 also provide a stable supporting point for the decorative plate 2 to prevent the decorative plate 2 from falling during the initial installation. The pre-positioning plates 3 are symmetrically arranged on the inner walls of the upper side plate 2-2 and the lower side plate 2-3, so as to ensure the balance and stability of the decorative plate 2 during installation. This symmetry also helps to reduce possible deviations during the installation process.

[0022] A limit piece 4 extending along the X direction and opening is provided on the inner wall of the outer plate 2-1, and a guide strip 5 matching the limit piece 4 is provided on the lamp housing 1. The opening setting of the limit piece 4 not only helps to simplify the installation process, but also helps the guide strip 5 on the lamp housing 1 to accurately match it. The limit piece 4 matches with the guide strip 5 after moving a distance along the X direction. This matching mechanism is the key to ensuring the correct installation of the decorative panel 2 and provides the necessary guidance and positioning. The matching between the pre-positioning plate 3 and the lamp housing 1 ensures that the guide strip 5 will not deviate in the Z direction when moving along the X direction, thereby assisting the limit piece 4 to be stuck on the guide strip 5. When the limit piece 4 is stuck on the guide strip 5, the clamping structure of the two makes the decorative panel 2 unable to move in the Y direction, forming a stable clamping structure, thereby ensuring that the decorative panel 2 is accurately positioned in the Y direction.

[0023] A plurality of Z-direction positioning posts 6 are provided at the rear section of the inner wall of the outer side plate 2-1. The Z-direction positioning posts 6 not only provide precise Z-direction positioning, but also provide necessary support for the fixation of the decorative panel 2. A first elastic clamping component 7 is provided on the lamp housing 1 for the Z-direction positioning posts 6 to be laterally clamped. The sliding of the decorative panel 2 in the X-direction enables the first elastic clamping component 7 to be clamped on the Z-direction positioning posts by elastic force. When disassembling, it is only necessary to apply a pulling force greater than the elastic force of the first elastic clamping component 7 in the X-direction. The Z-direction positioning posts 6 and the first elastic clamping component 7 can achieve a certain degree of fixed fit. This fixed fit can be used to locate the X-direction position of the decorative panel 2. This fixed fit not only improves the installation accuracy of the decorative panel 2, but also enhances its stability during use.

[0024] A Y-direction positioning column 8 is provided on the upper side plate 2-2 or the lower side plate 2-3. The Y-direction positioning column 8 can position the decorative plate 2 in the Y direction. The structure of the Y-direction positioning column 8 is the same as that of the Z-direction positioning column 6. A second elastic clamping component 9 is provided on the lamp housing 1 for the Y-direction positioning column 8 to be laterally clamped. The structure of the second elastic clamping component 9 is the same as that of the first elastic clamping component 7. The cooperation mode of the Y-direction positioning column 8 and the second elastic clamping component 9 is the same as the cooperation mode of the Z-direction positioning column 6 and the first elastic clamping component 7. The cooperation between the Y-direction positioning column 8 and the second elastic clamping component 9 can also locate the X-direction position of the decorative plate 2.

[0025] See attached Figure 1 , 2 , 3, 6: A pair of pre-positioning plates 3 are in the form of thin sheets, the purpose of which is to reduce the impact on the coordination of other components and save materials. The distance between the pair of pre-positioning plates 3 is designed to be just slightly larger than the length of the lamp housing 1, so as to facilitate the alignment of the decorative plate 2 with the lamp housing 1. The end of the pre-positioning plate 3 in contact with the lamp housing 1 is provided with an arc-shaped guide edge 3a, which not only provides a smooth transition area, but also enables the pair of pre-positioning plates 3 to be smoothly sleeved on both sides of the lamp housing 1. The curvature of the arc-shaped guide edge 3a is customized according to the size of the lamp housing 1 to ensure that the pair of pre-positioning plates 3 can be positioned smoothly and accurately during the installation process; when the lamp housing 1 enters between the pre-positioning plates 3 along the arc-shaped guide edge 3a, this action is designed to be smooth and controllable. The guiding effect of the arc-shaped guide edge 3a reduces the friction and resistance that may occur during the installation process, and also reduces the risk of damage caused by improper operation. In addition, the arc-shaped guide edge 3a also helps to ensure that the lamp housing 1 maintains the correct direction during the installation process, which is crucial for subsequent assembly work.

[0026] See attached Figure 1~Figure 5: The limiting member 4 includes a Y-direction limiting plate 4-1 having a spacing from the outer side plate 2-1, and a connecting plate 4-2 provided at the bottom end of the Y-direction limiting plate 4-1 and fixedly connecting the Y-direction limiting plate 4-1 to the outer side plate 2-1. The Y-direction limiting plate 4-1 and the connecting plate 4-2 are combined to form an L shape. The Y-direction limiting plate 4-1 is the long side of the L shape, and the connecting plate 4-2 is the short side of the L shape. The combination of the Y-direction limiting plate 4-1, the connecting plate 4-2, and the outer side plate 2-1 forms a 丩-shaped structure. The guiding strip 5 is arranged as a flanged long strip along the edge of the lamp housing 1. The function of the flanged long strip is similar to a hook, which is used to hook the 丩-shaped structure formed by the combination of the Y-direction limiting plate 4-1, the connecting plate 4-2, and the outer side plate 2-1. The decorative plate 2 drives the Y-direction limiting plate 4-1 to move along the X direction, so that the guiding strip 5 enters between the Y-direction limiting plate 4-1 and the outer side plate 2-1. When the guiding strip 5 is located between the Y-direction limiting plate 4-1 and the outer side plate 2-1, the decorative plate 2 is restricted in the Y direction by the Y-direction limiting plate 4-1. When the decorative plate 2 moves along the X direction, the connecting plate 4-2 contacts and collides with the guiding strip 5 to prevent the decorative plate 2 from continuing to move along the X direction, thereby reminding the operator that the decorative plate 2 has slid to the correct position in the X direction; in addition, two limiting members 4 are provided and the angle between the two limiting members 4 is less than 180 degrees. When the two limiting members 4 are stuck on the guiding strip 5, they can restrict the movement of the decorative plate 2 in the Z direction.

[0027] Refer to the appendix Figure 1 、 2, 3, 7, 8: The Z-direction positioning column 6 is fixed on the outer plate 2-1 and is provided with an extended folded edge 6a at the top. The main function of the extended folded edge 6a is to limit the movement of the first elastic clamping component 7 in the Y direction, thereby ensuring that the decorative panel 2 maintains the correct position during the assembly process. When the first elastic clamping component 7 is clamped on the Z-direction positioning column 6, it is located between the extended folded edge 6a and the outer plate 2-1. The first elastic clamping component 7 includes a pair of elastic strips 7-1 fixed on the lamp housing 1 and with a spacing smaller than the diameter of the Z-direction positioning column 6. The elastic strips 7-1 can apply pressure to the outer side of the Z-direction positioning column 6 by generating elastic deformation, thereby ensuring that the elastic strips 7-1 can be tightly clamped on the outer side of the Z-direction positioning column 6. The arc clamping groove 7-2 is arranged on the inner side of the pair of elastic strips 7-1 and can cooperate with the outer side of the Z-direction positioning column 6. The arc clamping groove 7-2 can accurately cooperate with the outer side of the Z-direction positioning column 6 The pressure generated by a pair of elastic strips 7-1 can make the arc groove 7-2 fit tightly against the outer side of the Z-direction positioning column 6, and the Z-direction positioning column 6 cannot be separated from the arc groove 7-2 without applying a certain pressure, thereby locking the position of the decorative panel 2 in the X direction to a certain extent. An expansion opening 7-3 is provided on the inner side of a pair of elastic strips 7-1 and connected to the arc groove 7-2. The shape of the expansion opening 7-3 is similar to a V-shape opening outward. The Z-direction positioning column 6 opens a pair of elastic strips 7-1 through the expansion opening 7-3 and enters the arc groove 7-2. Generally speaking, the extended fold 6a limits the movement of the decorative panel 2 in the Y direction. Multiple Z-direction positioning columns 6 and the elastic strips 7-1 cooperate to limit the movement of the decorative panel 2 in the Z direction. The matching parts of the elastic strips 7-1 and the arc groove 7-2 limit the movement of the decorative panel 2 in the X direction.

[0028] See attached Figure 1 , 2 , 3, 7, 8: The Y-direction positioning column 8 is fixed on the upper side plate 2-2 or the lower side plate 2-3. The structure of the Y-direction positioning column 8 is the same as that of the Z-direction positioning column 6. The extended folded edge 6a on the Z-direction positioning column 6 can be selectively set on the Y-direction positioning column 8 as needed. The Y-direction positioning column 8 and the Z-direction positioning column 6 are approximately at a 90-degree angle. The second elastic clamping component 9 has the same structure as the first elastic clamping component 7. The second elastic clamping component 9 cooperates with the Y-direction positioning column 8 to limit the movement of the decorative panel 2 in the Y and X directions.

[0029] See attached Figure 1 to Figure 8: A plurality of pairs of vertical plates 10 are formed on the outer plate 2-1, and the vertical plates 10 are vertically installed on the inner side of the outer plate 2-1. An X-direction channel 11 is formed between the vertical plates 10, and the X-direction channel 11 is set to penetrate along the X-direction. A sliding vertical bar 12 cooperating with the X-direction channel 11 is installed on the lamp housing 1. When the vertical bar 12 is located inside the X-direction channel 11, it can slide along the X-direction channel 11 in the X-direction, but the movement in the Z-direction is restricted. The vertical bar 12 guides the first elastic clamping component 7 to align and clamp on the Z-direction positioning column 6 by sliding in the X-direction channel 11, and guides the second elastic clamping component 9 to align and clamp on the Y-direction positioning column 6. On the column 8, the X-direction channel 11 includes a V-shaped wide mouth portion 11-1 for roughly guiding the vertical bars 12 and a narrow mouth portion 11-2 for accurately guiding the vertical bars 12. The spacing of the V-shaped wide mouth portion 11-1 is greater than the width of the vertical bars 12, and the spacing of the narrow mouth portion 11-2 is coordinated with the width of the vertical bars 12. Because it is difficult to align the vertical bars 12 with the narrow mouth portion 11-2 when it is invisible, a V-shaped wide mouth portion 11-1 is set at one end of the narrow mouth portion 11-2, so that the V-shaped wide mouth portion 11-1 first preliminarily guides the vertical bars 12. As the decorative panel 2 moves in the X direction, the vertical bars 12 can slide smoothly and accurately into the narrow mouth portion 11-2.
