Description

Technical Field

[0001] This utility model belongs to the field of automotive lighting technology, specifically relating to a car light with an optical module that can change patterns. Background Technology

[0002] As a key component of automobiles, headlights not only provide basic illumination for vehicles at night or in low-visibility environments, but their luminous effects and patterns also directly impact vehicle visibility, aesthetics, and driving safety. With the rapid development of the automotive industry and the continuous upgrading of consumer demands, traditional headlights with simple structures and fixed lighting effects can no longer meet the market's demand for personalized and multifunctional automotive accessories. Headlights with pattern-changing capabilities have gradually become a hot topic in industry research and application. However, existing headlights with pattern-changing optical modules still face many problems that urgently need to be solved in actual production and use.

[0003] On the one hand, in the assembly of automotive lights, the connection between the lamp cover and the main body is mostly achieved through bolt fastening or simple snap-fit ​​structures. Bolt fastening leads to low assembly and disassembly efficiency, which is detrimental to later maintenance and repair. Simple snap-fit ​​structures, on the other hand, suffer from poor connection stability, making the lamp cover prone to loosening or even detachment due to vibrations during vehicle operation, affecting the normal use of the light. On the other hand, the optical module generates a large amount of heat during the illumination process. If this heat cannot be dissipated in a timely and effective manner, it will accumulate inside the light headlight housing, causing the internal temperature to rise. Excessive temperature not only affects the luminous efficiency and pattern display effect of the optical module but also accelerates the aging of the internal electronic components, shortens the lifespan of the light, and in severe cases, may even cause safety hazards such as short circuits in the optical module.

[0004] Furthermore, the wiring harness of the vehicle headlights, as a key component connecting the headlights to the vehicle's electrical circuit, directly affects the reliability of the headlight power supply due to its installation stability. Currently, most wiring harnesses are installed using soldering or simple snap-fit ​​methods. Soldering is not only cumbersome but also makes disassembly and replacement difficult if a fault occurs later. Simple snap-fit ​​methods, on the other hand, suffer from weak connections, which can easily become loose or lead to poor contact under the vibrations of long-term vehicle operation, causing the headlights to flicker or even go out, seriously threatening driving safety.

[0005] Based on the shortcomings of the existing technology, there is an urgent need to develop an optical module with a changeable pattern that features a convenient assembly structure, efficient heat dissipation, and stable wiring structure. This would solve the problems of low assembly efficiency, poor heat dissipation, and insufficient wiring stability in existing products, and meet the automotive industry's demand for high-quality headlights. Utility Model Content

[0006] This utility model addresses the shortcomings of existing technologies by providing a vehicle light with an optical module capable of changing patterns. The specific technical solution is as follows: An optical module-modified vehicle light includes a light housing and a connector integrally formed on one side of the light housing. An optical module is mounted on one end of the light housing at the connector. A lampshade connected to the connector is mounted on the end of the light housing. A lens is mounted on the end of the lampshade. A snap-fit ​​is provided between the connector and the lampshade. A heat dissipation mechanism is mounted on the outer surface of the light housing. A support column is integrally formed on the end of the light housing away from the connector. A support plate is provided at the end of the support column. A locking screw is installed in a hole on the surface of the support plate, and the end of the locking screw is screwed into a screw hole at the end of the support column. A connector is fixed in the middle of the support plate.

[0007] Preferably, the snap-fit ​​component includes a snap-fit ​​plate and a limiting post integrally formed at one end of the lampshade near the connecting seat. The snap-fit ​​plate is located outside the limiting post, and a limiting hole is provided on the connecting seat. When the limiting post is inserted into the limiting hole, the snap-fit ​​plate is snapped onto the outside of the connecting seat.

[0008] Preferably, there are three of each of the card plate, limiting post, and limiting hole, and the card plate, limiting post, and limiting hole correspond one-to-one.

[0009] Preferably, the heat dissipation mechanism includes a heat dissipation fan installed at the end of the headlight housing and an aluminum foil plate welded to the outer surface of the headlight housing. The stator of the heat dissipation fan located in the middle is fixed to the headlight housing, and the stator of the heat dissipation fan has a hollow structure. The wire of the terminal block passes through the hollow structure of the stator of the heat dissipation fan and is electrically connected to the optical module at the end of the headlight housing. The rotor housing of the heat dissipation fan is integrally formed with fan blades.

[0010] Preferably, the aluminum foil plates are arranged in a ring array with equal spacing.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The snap-fit ​​connector between the connector and the lamp cover facilitates the connection between the lamp cover and the connector. The heat dissipation mechanism installed on the outer surface of the lamp housing facilitates heat dissipation, thus solving the problem of inconvenient heat dissipation when the optical module installed at the end of the lamp housing is powered on. The wiring terminal installed on the support plate is fixed to the support column with locking screws, which facilitates the fixing of the wiring terminal to the end of the lamp housing and makes it easy to connect the wiring terminal to the car's circuit during lamp installation.

[0012] 2. The snap-fit ​​connector, consisting of a snap plate, a limiting post, and a limiting hole, facilitates the connection between the lamp cover and the connector. When the lamp cover is connected to the connector, the limiting post is inserted into the limiting hole, and the snap plate is snapped onto the outside of the connector, thereby achieving the purpose of fixing the connector to the lamp cover. At the same time, the lamp cover protects the optical module at the end of the vehicle lamp housing. There are three snap plates, three limiting posts, and three limiting holes to facilitate the connection between the connector and the lamp cover through the snap-fit ​​connector.

[0013] 3. A heat dissipation mechanism consisting of a cooling fan and aluminum foil plates is used. The stator of the cooling fan, located in the middle, is fixed to the headlight housing, allowing the wires of the connector to pass through the hollow structure of the cooling fan stator, thus enabling the connector to be electrically connected to the optical module. This prevents the cooling fan from affecting the wires of the connector when it is working. The aluminum foil plates are welded in a ring array to the surface of the headlight housing, increasing the contact area between the headlight housing and the air, thereby facilitating heat dissipation of the headlight housing through the heat dissipation mechanism and preventing the optical module from overheating when it is powered on.

[0016] The technical solution of this utility model will now be described with reference to the accompanying drawings and embodiments.

[0017] Please see Figure 1-5This embodiment provides the following technical solution: a vehicle lamp with an optical module that can change patterns, including a vehicle lamp housing 1 and a connecting seat 2 integrally formed on one side of the vehicle lamp housing 1. An optical module 3 is installed on one end of the vehicle lamp housing 1 located on the connecting seat 2. A lamp cover 4 connected to the connecting seat 2 is installed on the end of the vehicle lamp housing 1. A lens 5 is installed on the end of the lamp cover 4. A snap-fit ​​is provided between the connecting seat 2 and the lamp cover 4. A heat dissipation mechanism is installed on the outer surface of the vehicle lamp housing 1. A support column 9 is integrally formed on the end of the vehicle lamp housing 1 away from the connecting seat 2. A support plate 10 is provided at the end of the support column 9. A locking screw 11 is installed in a hole opened on the surface of the support plate 10, and the end of the locking screw 11 is screwed into a screw hole opened at the end of the support column 9. A connector 12 is fixed in the middle of the support plate 10.

[0018] In this embodiment, the snap-fit ​​connector provided between the connector 2 and the lamp cover 4 facilitates the connection of the lamp cover 4 to the connector 2 via the snap-fit ​​connector. The heat dissipation mechanism installed on the outer surface of the lamp housing 1 facilitates the heat dissipation of the lamp housing 1, thereby solving the problem of inconvenient heat dissipation when the optical module 3 installed at the end of the lamp housing 1 is powered on. The connector 12 installed on the support plate 10 is fixed to the support column 9 by the locking screw 11, which facilitates the fixing of the connector 12 at the end of the lamp housing 1 and facilitates the connection of the connector 12 to the circuit of the car when the lamp is installed.

[0019] Specifically, the snap-fit ​​component includes a snap-fit ​​plate 6 and a limiting post 7 integrally formed at one end of the lampshade 4 near the connecting seat 2. The snap-fit ​​plate 6 is located outside the limiting post 7. A limiting hole 8 is opened on the connecting seat 2. When the limiting post 7 is inserted into the limiting hole 8, the snap-fit ​​plate 6 is snapped outside the connecting seat 2. There are three snap-fit ​​plates 6, three limiting posts 7 and three limiting holes 8, and each of the snap-fit ​​plates 6, three limiting posts 7 and three limiting holes 8 corresponds to one another.

[0020] In this embodiment, the snap-fit ​​connector, consisting of a snap plate 6, a limiting post 7, and a limiting hole 8, facilitates the connection between the lamp cover 4 and the connecting seat 2. When the lamp cover 4 is connected to the connecting seat 2, the limiting post 7 is inserted into the limiting hole 8, and the snap plate 6 is snapped onto the outside of the connecting seat 2, thereby achieving the purpose of fixing the connecting seat 2 and the lamp cover 4. At the same time, the lamp cover 4 protects the optical module 3 at the end of the vehicle lamp housing 1. Three snap plates 6, three limiting posts 7, and three limiting holes 8 are provided to facilitate the connection between the connecting seat 2 and the lamp cover 4 through the snap-fit ​​connector.

[0021] Specifically, the heat dissipation mechanism includes a cooling fan 13 installed at the end of the headlight housing 1, and an aluminum foil plate 14 welded to the outer surface of the headlight housing 1. The headlight housing 1 is an aluminum alloy casting with a wire channel. The stator of the cooling fan 13 is fixed to the headlight housing 1 in the middle. The stator of the cooling fan 13 has a hollow structure and is connected to the wire channel. The wires of the connector 12 pass through the hollow structure of the stator of the cooling fan 13 and the wire channel of the headlight housing 1 in sequence, and are electrically connected to the optical module 3 at the end of the headlight housing 1. The rotor housing of the cooling fan 13 is integrally formed with fan blades, and the aluminum foil plates 14 are arranged in a ring array at equal intervals.

[0022] In this embodiment, a heat dissipation mechanism consisting of a cooling fan 13 and an aluminum foil plate 14 is used. The stator of the cooling fan 13, located in the middle, is fixed to the headlight housing 1, which facilitates the wires of the connector 12 to pass through the hollow structure of the stator of the cooling fan 13 and then through the wire channel to achieve electrical connection between the connector 12 and the optical module 3. This prevents the cooling fan 13 from affecting the wires of the connector 12 when it is working. The aluminum foil plate 14 is welded in a ring array on the surface of the headlight housing 1, increasing the contact area between the headlight housing 1 and the air, thereby facilitating heat dissipation of the headlight housing 1 through the heat dissipation mechanism and preventing the optical module 3 from overheating when it is powered on to emit light.

[0023] How to use: Assembly of lampshade and connector Alignment and positioning: Hold the lamp cover 4 and make the end of it close to the connector 2 face the connector 2 on the headlight housing 1. Ensure that the three limiting posts 7 on the lamp cover 4 correspond one-to-one with the three limiting holes 8 on the connector 2. At the same time, ensure that the clip 6 on the lamp cover 4 (located outside the limiting posts 7) is aligned with the outer edge of the connector 2.

[0024] Snap-fit ​​fixing: Gently push the lamp cover 4 so that the limiting post 7 is smoothly inserted into the corresponding limiting hole 8 until the locking plate 6 is firmly locked onto the outside of the connecting seat 2. At this time, it is necessary to confirm that the snap-fit ​​is firm and that the lamp cover 4 is not loose. The fixing of the lamp cover 4 and the connecting seat 2 is completed. The lamp cover 4 provides protection for the optical module 3 at the end of the headlight housing 1.

[0025] Assembly of support plate and connector Pre-installation of connector: Fix connector 12 in the middle of support plate 10, ensuring that connector 12 is tightly connected to support plate 10 (how connector 12 is installed on support plate 10 is existing technology and will not be described here), then align support plate 10 with support post 9 at the end of headlight housing 1 away from connector 2.

[0026] Tightening and fixing: Take out the locking screw 11, pass it through the hole opened on the surface of the support plate 10, align it with the screw hole at the end of the support column 9, and use a screwdriver to rotate the locking screw 11 clockwise until the support plate 10 is firmly fixed to the end of the support column 9, ensuring that the connector 12 is installed stably and avoiding loosening during subsequent wiring or use.

[0027] Line connection between optical module and connector Wire arrangement: Take out the wire from connector 12 and pass it through the hollow structure of the stator of cooling fan 13 (the stator in the middle of cooling fan 13 is fixed to the headlight housing 1, and the hollow structure design can avoid the wire being affected by the operation of cooling fan 13), and then pass it out through the wire channel.

[0028] Electrical connection operation: Connect the wires passing through the hollow structure and the wire channel to the optical module 3 to ensure accurate and secure wiring connections, avoid problems such as poor contact, and ensure that the optical module 3 can be powered on and emit light and perform pattern transformation functions normally.

[0029] Vehicle headlight installation and adjustment Overall installation of vehicle lights Align the assembled headlight with the headlight mounting position on the car, install the external screws in the appropriate position on the headlight through the connector 2, and then tighten the screws to fix the headlight in place.

[0030] Circuit connection and function debugging Circuit connection: Connect the terminal 12 on the support plate 10 to the corresponding circuit system of the vehicle, ensuring that the wiring is correct and complies with the vehicle circuit safety specifications.

[0031] Functional test: Connect the car's electrical circuit and turn on the headlights. Check whether the optical module 3 is powered on and illuminates normally, and whether the pattern changing function is smooth. At the same time, observe the light transmission effect of lens 5 to ensure that the light projection meets the usage requirements.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
