Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically a dual-lens mounting structure for a curved headlight. Background Technology

[0002] As automotive styling increasingly emphasizes streamlined designs and low drag, curved headlights have become a mainstream feature. These lights typically consist of a curved lens, dual optical modules, a housing, and a mounting bracket. The lamp holder is secured to the front of the vehicle using multiple bolts, and the headlight assembly is then connected to the lamp holder via bolts or clips. However, in real-world road conditions, the probability of minor collisions or scrapes at the front of a vehicle is extremely high. Typically, minor accidents only result in cracks in the lamp housing or lens, while the metal lamp holder and its internal wiring remain intact.

[0003] The existing technology has the following main shortcomings:

[0004] Traditional solutions use multiple bolts to secure the headlight assembly to the lamp holder. Due to the curved shape, the working space is limited, and maintenance personnel must use a socket wrench to remove the bolts one by one, which takes a long time on average. More importantly, the back of the lamp holder integrates the headlight wiring harness, dimming motor wiring harness, and sensor wiring harness. After removing the bolts, multiple sets of connectors still need to be disconnected, which can easily cause terminal deformation or secondary damage.

[0005] In order to achieve quick removal, some models use conventional clip structures made of ABS or PA66 plastic. However, curved headlights are constantly subjected to vibration and thermal expansion and contraction during driving. The fatigue life of plastic clips is insufficient, and they are prone to breakage or disengagement during collisions. Utility Model Content

[0006] The purpose of this invention is to provide a dual-lens mounting structure for a curved headlight to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A dual-lens mounting structure for a curved headlight includes a headlight and a lamp holder, wherein the lamp holder can be fixed to the vehicle body by bolts, and a base plate is provided on the headlight.

[0009] A snap-fit ​​assembly is provided between the lamp holder and the base plate. The base plate can be quickly fixed to the lamp holder through the snap-fit ​​assembly, thereby realizing the fixed installation of the vehicle lamp and the lamp holder.

[0010] The vehicle headlight is provided with a male connector, and the lamp holder is provided with a female connector. When the vehicle headlight and the lamp holder are fixedly connected, the male connector and the female connector are in a plug-in state.

[0011] The base plate is provided with an unlocking component, which allows the vehicle light to be quickly removed when it is damaged and needs to be disassembled.

[0012] As a further embodiment of this utility model:

[0013] The snap-fit ​​assembly includes a plug and a sleeve, wherein the sleeve is adapted to the plug;

[0014] The insertion rod is disposed on the base plate, and the sleeve is disposed on the lamp holder.

[0015] As a further improvement of this utility model:

[0016] A slider is slidably disposed inside the sleeve, and a No. 1 spring is installed inside the sleeve;

[0017] The two ends of the first spring abut against the inner wall of the slider and the sleeve, respectively, so as to drive the slider to always have a tendency to move towards the opening of the sleeve.

[0018] As a further improvement of this utility model:

[0019] The substrate has a plurality of wedge-shaped blocks on its circumferential surface, and the lamp holder opening has a plurality of wedge-shaped grooves on one side. The plurality of wedge-shaped blocks and the plurality of wedge-shaped grooves are adapted to each other and are evenly distributed along the circumference.

[0020] As the substrate approaches the lamp holder, the multiple wedge blocks and multiple wedge grooves guide the insertion rod to be smoothly inserted into the sleeve, thereby further compressing the first spring.

[0021] As a further improvement of this utility model:

[0022] The snap-fit ​​assembly further includes a guide rod and a slide block. One end of the guide rod is fixedly connected to the insertion rod, and the length direction of the guide rod is perpendicular to the length direction of the insertion rod.

[0023] The slide block is slidably mounted on the guide rod along the length of the guide rod. A second spring is sleeved on the outer wall of the guide rod. The two ends of the second spring abut against the insert rod and the slide block respectively, so as to drive the slide block to always tend to move away from the insert rod.

[0024] As a further improvement of this utility model:

[0025] A triangular block is provided on the side of the slide away from the plug rod, and a hook plate is provided on the lamp holder;

[0026] The inclined surface of the triangular block corresponds to the inclined surface of the hook plate. When the insertion rod is inserted into the sleeve, the inclined surface of the hook plate will abut against the inclined surface of the triangular block and push the triangular block and the slide block to slide on the guide rod in the direction of the insertion rod. At this time, the second spring is compressed. When the inclined surface of the hook plate separates from the inclined surface of the triangular block, the slide block and the triangular block will reset under the action of the second spring. At the same time, under the action of the first spring, the straight surface of the triangular block and the straight surface of the hook plate will remain in close contact.

[0027] As a further improvement of this utility model:

[0028] The unlocking component includes a disc and a slide bar. The disc is rotatably mounted on the base plate, and one end of the slide bar is fixedly connected to the triangular block.

[0029] The disc has an arc-shaped groove, the other end of the slide rod is located in the arc-shaped groove and slides in cooperation with it, and the disc has a swing rod on its circumference.

[0030] When unlocking, external force is used to rotate the disc via the swing rod, causing the arc groove and the slide rod to cooperate with each other, so that the triangular block and the slide block slide on the guide rod towards the insertion rod, thereby releasing the engagement between the triangular block and the hook plate.

[0031] Compared with the prior art, the beneficial effects of this utility model are:

[0032] By replacing traditional bolts with snap-fit ​​components, the installation and removal process of vehicle lights is significantly simplified. In existing technologies, when vehicle lights are damaged in a collision, repair personnel need to use tools to loosen multiple bolts one by one, disassemble the undamaged lamp holder and the light as a whole, and simultaneously disassemble the complex wiring harness connected to it. Repeated disassembly and assembly can easily lead to wear of the wiring harness or loosening of the interfaces. However, this solution utilizes the snap-fit ​​design between the base plate and the lamp holder, which only requires operating the unlocking component to quickly separate the light without disassembling the lamp holder, thus improving repair efficiency. In addition, the snap-fit ​​component has optimized structural rigidity to ensure that the connection remains stable during a collision, avoiding the safety hazard of the light falling off due to snap-fit ​​failure, thus combining convenience and reliability.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] Furthermore, the elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0044] Please see Figures 1-8 In this embodiment of the utility model, a dual-lens mounting structure for a curved headlight includes a headlight 1 and a lamp holder 2. The lamp holder 2 can be fixed to the vehicle body by bolts, and a base plate 3 is provided on the headlight 1.

[0045] A snap-fit ​​assembly is provided between the lamp holder 2 and the base plate 3. The base plate 3 can be quickly fixed to the lamp holder 2 through the snap-fit ​​assembly, thereby realizing the fixed installation of the vehicle lamp 1 and the lamp holder 2.

[0046] The vehicle light 1 is provided with a male connector 4, and the lamp holder 2 is provided with a female connector 5. When the vehicle light 1 and the lamp holder 2 are fixedly connected, the male connector 4 and the female connector 5 are in the plug-in state.

[0047] The base plate 3 is provided with an unlocking component. When the headlight 1 is damaged and needs to be disassembled, the headlight 1 can be quickly removed by the unlocking component.

[0048] In this scheme, a fixed reference is established, and the lamp holder 2 is pre-locked to the vehicle body by bolts to form a rigid reference for the entire system and to bear all wiring harnesses;

[0049] A single action completes dual coupling:

[0050] Mechanical coupling: the base plate 3 moves along with the vehicle lamp 1 towards the lamp holder 2, and the snap-fit ​​assembly automatically slides into the locking position under the action of the guide slope;

[0051] Electrical coupling occurs simultaneously, with the male connector 4 on the headlight 1 and the female connector 5 on the lamp holder 2 interlocked along the same translation axis to achieve power and signal conduction.

[0052] The two steps described above are completed simultaneously in a single insertion action, requiring no additional operations;

[0053] The locking mechanism is engaged. After the locking assembly enters the locking position, its elastic locking tongue forms an interference fit with the stop of the lamp holder 2, providing bidirectional constraints of longitudinal anti-disengagement and lateral shear resistance, ensuring that the lamp 1 and lamp holder 2 remain reliably connected during driving vibrations or collisions.

[0054] Quick decoupling: When headlight 1 is damaged and needs to be replaced, the maintenance personnel only need to trigger the unlocking component on the base plate 3, and the elastic locking tongue will instantly retract from the stop. At this time, headlight 1 can be moved in the opposite direction, so that the snap-fit ​​component and male connector 4 can be disengaged from the lamp holder 2 and female connector 5 at the same time, realizing quick replacement of headlight 1 by disassembling it separately while retaining lamp holder 2 and wiring harness in their original positions.

[0055] As a further embodiment of this utility model, the snap-fit ​​assembly includes a plug 6 and a sleeve 7, wherein the sleeve 7 is adapted to the plug 6;

[0056] The insertion rod 6 is disposed on the base plate 3, and the sleeve 7 is disposed on the lamp holder 2;

[0057] A slider 8 is slidably disposed inside the sleeve 7, and a first spring 9 is installed inside the sleeve 7;

[0058] The two ends of the first spring 9 abut against the inner sidewalls of the slider 8 and the sleeve 7 respectively, so as to drive the slider 8 to always have a tendency to move towards the opening of the sleeve 7.

[0059] The substrate 3 has a plurality of wedge-shaped blocks 10 on its circumferential surface, and the lamp holder 2 has a plurality of wedge-shaped grooves 11 on one side of its opening. The plurality of wedge-shaped blocks 10 and the plurality of wedge-shaped grooves 11 are adapted to each other and are evenly distributed along the circumference.

[0060] When the substrate 3 approaches the lamp holder 2, the multiple wedge blocks 10 and multiple wedge grooves 11 will guide the insertion rod 6 to be smoothly inserted into the sleeve 7, thereby further compressing the first spring 9.

[0061] In this embodiment, when the substrate 3 moves the entire vehicle lamp 1 closer to the lamp holder 2, several wedge-shaped blocks 10 on the circumferential surface of the substrate 3 first form a "cone-hole" fit with the corresponding wedge-shaped groove 11 at the opening of the lamp holder 2; the wedge-shaped inclined surfaces are evenly distributed in the circumferential direction, so that the radial alignment is automatically performed during the insertion process, eliminating the angle deviation, and providing guidance for the precise coaxial insertion of the subsequent insertion rod 6 and sleeve 7.

[0062] As the wedge block 10 continues to penetrate deeper into the wedge groove 11, the axial displacement of the substrate 3 relative to the lamp holder 2 is forced to synchronize; the insert rod 6 fixed to the substrate 3 thus enters the sleeve 7 along the axial trajectory and pushes the slider 8 inside the sleeve 7; the slider 8 overcomes the elastic force of the first spring 9 and slides backward, the first spring 9 is further compressed, converting mechanical energy into elastic potential energy, and at the same time generating a continuous forward reaction force, providing preload for subsequent locking.

[0063] As a further embodiment of this utility model, the snap-fit ​​assembly further includes a guide rod 12 and a slide block 13. One end of the guide rod 12 is fixedly connected to the insertion rod 6, and the length direction of the guide rod 12 is perpendicular to the length direction of the insertion rod 6.

[0064] The slide block 13 is slidably disposed on the guide rod 12 along the length direction of the guide rod 12. A second spring 14 is sleeved on the outer wall of the guide rod 12. The two ends of the second spring 14 abut against the insertion rod 6 and the slide block 13 respectively, so as to drive the slide block 13 to always have a tendency to move away from the insertion rod 6.

[0065] A triangular block 15 is provided on the side of the slide block 13 away from the insertion rod 6, and a hook plate 16 is provided on the lamp holder 2;

[0066] The inclined surface of the triangular block 15 corresponds to the inclined surface of the hook plate 16. When the insertion rod 6 is inserted into the sleeve 7, the inclined surface of the hook plate 16 will abut against the inclined surface of the triangular block 15 and push the triangular block 15 and the slide block 13 to slide on the guide rod 12 toward the insertion rod 6. At this time, the second spring 14 is compressed. When the inclined surface of the hook plate 16 separates from the inclined surface of the triangular block 15, the slide block 13 and the triangular block 15 will be reset under the action of the second spring 14. At the same time, under the action of the first spring 9, the straight surface of the triangular block 15 and the straight surface of the hook plate 16 are kept in close contact.

[0067] In this embodiment, as the insertion rod 6 enters the sleeve 7 axially, the guide rod 12 and its slide block 13 and triangular block 15 move together.

[0068] When the inclined surface of the triangular block 15 meets the inclined surface of the hook plate 16 fixed to the lamp holder 2, the hook plate 16 generates a normal force perpendicular to the inclined surface on the triangular block 15; this force is decomposed into a component along the axial direction of the guide rod 12, which pushes the slide block 13 to slide towards the insertion rod 6, and the second spring 14 is compressed to store energy. This process allows the triangular block 15 to "avoid" the hook plate 16, ensuring that the insertion rod 6 can continue to penetrate.

[0069] Once the triangular block 15 passes the top of the inclined surface of the hook plate 16, the two inclined surfaces separate, the second spring 14 is released, and the slide block 13 and the triangular block 15 are pushed outward to reset quickly.

[0070] At this time, the first spring 9 drives the slider 8 to always tend to move towards the opening of the sleeve 7, so that the straight surface of the triangular block 15 and the straight surface of the hook plate 16 abut against each other, forming a "straight surface-straight surface" positive locking, preventing the insert rod 6 from retracting in the opposite direction.

[0071] The wedge block 10 and wedge groove 11 provide circumferential positioning, while the insert rod 6 and sleeve 7 provide axial positioning, achieving a dual reliable mechanical and electrical connection.

[0072] As a further embodiment of this utility model, the unlocking component includes a disc 17 and a slide bar 18. The disc 17 is rotatably mounted on the base plate 3, and one end of the slide bar 18 is fixedly connected to the triangular block 15.

[0073] The disc 17 has an arc-shaped groove 19, the other end of the slide rod 18 is located in the arc-shaped groove 19 and slides in cooperation with it, and the circumferential surface of the disc 17 is provided with a swing rod 20.

[0074] When unlocking, the disk 17 is rotated by the swing rod 20 with the help of external force, so that the arc groove 19 and the slide rod 18 cooperate with each other, so that the triangular block 15 and the slide seat 13 slide on the guide rod 12 towards the insertion rod 6, thereby releasing the engagement between the triangular block 15 and the hook plate 16.

[0075] In this embodiment, the maintenance personnel move the rocker arm 20 to drive the disc 17 to rotate circumferentially around its central axis on the base plate 3; when the disc 17 rotates, the side wall of its arc groove 19 pushes the slide rod 18 located in the groove. As the radius of curvature of the arc groove 19 gradually changes, the slide rod 18 is forced to produce a linear displacement along the axial direction of the guide rod 12.

[0076] The slide bar 18 is fixedly connected to the triangular block 15. Therefore, the triangular block 15 slides synchronously with the slide bar 18 towards the insertion rod 6, compressing the second spring 14, so that the straight surface of the triangular block 15 is disengaged from the straight surface of the hook plate 16, thereby releasing the dead point of the locking.

[0077] When the external force is removed, the second spring 14 pushes the slide block 13 and the triangular block 15 to move outward, and the slide rod 18 drives the disc 17 to reset in the opposite direction; at the same time, the first spring 9 pops the plug rod 6 out of the sleeve 7, realizing the quick disassembly of the lamp body.

[0078] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
