Description

Technical Field

[0001] This utility model relates to the field of LED lamp housing technology for electric vehicles, and in particular to an LED lamp housing for electric vehicles with high heat dissipation efficiency. Background Technology

[0002] With the popularization of two-wheeled and three-wheeled electric vehicles, LED vehicle lights have become the mainstream lighting solution due to their advantages such as high brightness, low energy consumption and long life. However, due to the complex driving environment of electric vehicles, the lights will generate a lot of heat when working for a long time. If the heat dissipation is not good, it will lead to accelerated LED light decay and even shorten the life. The heat dissipation design of traditional lamp housings is often unable to meet the heat dissipation requirements of high-power LEDs, especially under high temperature, dusty or frequent start-stop conditions. Insufficient heat dissipation efficiency directly affects the stability and reliability of the lights. Therefore, a high heat dissipation efficiency electric vehicle LED lamp housing is needed to ensure that the LED can maintain a high-efficiency and stable working state in harsh environments.

[0003] Existing LED light housings for electric vehicles typically employ passive heat dissipation structures, such as metal casings for heat conduction or simple heat sink fin designs. Some products add ventilation holes to enhance air convection, and some higher-end solutions introduce small cooling fans. In terms of dust prevention, most light housings use fixed dust filters, which can block some dust, but they are prone to clogging and difficult to clean after long-term use. In addition, the internal components of the light housing are usually fixed with screws or snap-fit ​​connections, making the disassembly and assembly process cumbersome and not conducive to quick maintenance or cleaning.

[0004] The main problem with existing technologies is that dustproof structures are prone to dust accumulation and are difficult to clean, leading to a gradual decrease in heat dissipation efficiency. Since dustproof nets are mostly fixed installations, dust accumulation will obstruct airflow, significantly reducing the efficiency of cooling fans and fins. Long-term dust accumulation not only affects the heat dissipation performance of LEDs, but also accelerates the aging of electronic components due to heat accumulation, and may even cause malfunctions. Therefore, how to design a dustproof structure that is easy to clean and can maintain long-term efficient heat dissipation has become a key challenge to improve the reliability of electric vehicle LED light housings. To address this issue, a high heat dissipation efficiency electric vehicle LED light housing is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an electric vehicle LED lamp housing with high heat dissipation efficiency, aiming to improve the problem in the prior art where excessive dust accumulation on the dustproof mesh plate hinders heat dissipation, leading to a decrease in the heat dissipation efficiency of the lamp housing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high heat dissipation efficiency electric vehicle LED lamp housing, comprising a lamp housing body, a lamp cover fixedly connected to the outer wall of the lamp housing body, a fixing plate provided inside the lamp housing body, a fixing frame fixedly connected inside the fixing plate, a heat dissipation component provided inside the fixing frame, and a connecting component provided inside the lamp housing body.

[0007] The heat dissipation assembly includes a cooling fan and cooling fins. The outer wall of the cooling fins is fixedly connected to the inside of the fixing frame. The cooling fan is disposed on the side wall of the cooling fins and its outer wall is fixedly connected to the inside of the fixing frame. A dustproof mesh plate is slidably connected inside the fixing frame. A lever is fixedly connected to the top and bottom of the dustproof mesh plate. A magnet is fixedly connected inside the fixing frame, and a magnet is fixedly connected inside the dustproof mesh plate. The magnet and the magnet attract each other.

[0008] As a further description of the above technical solution:

[0009] The connecting assembly includes a retaining ring, a locking block, and a locking groove formed inside the retaining plate, with the outer wall of the retaining ring fixedly connected to the inside of the lamp housing body.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the card block is fixedly connected to the side wall of the fixed ring, and the card block and the card slot engage with each other.

[0012] As a further description of the above technical solution:

[0013] The fixing plate has a sliding pin inside, and the locking block has a locking hole inside, and the locking pin and the locking hole engage with each other.

[0014] As a further description of the above technical solution:

[0015] A limiting plate is fixedly connected to the side wall of the card post, and the outer wall of the limiting plate is slidably connected inside the fixed plate.

[0016] As a further description of the above technical solution:

[0017] A connecting rod is fixedly connected to the outer wall of the limiting plate, and the outer wall of the connecting rod is slidably connected to the inside of the fixed plate. A pull block is fixedly connected to one end of the connecting rod.

[0018] As a further description of the above technical solution:

[0019] A reset spring is provided on the side wall of the limiting plate. One end of the reset spring is fixedly connected to the side wall of the limiting plate, and the other end of the reset spring is fixedly connected to the inside of the fixing plate.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the cooling fan and cooling fins work together to efficiently dissipate heat inside the lamp housing body. The dustproof mesh prevents dust from entering the lamp housing body. When cleaning is required, pulling the two levers can separate the second magnet inside the dustproof mesh from the first magnet inside the fixing frame, thus facilitating the cleaning of the dustproof mesh. This solves the problem of excessive dust accumulation on the dustproof mesh hindering heat dissipation and causing a decrease in the heat dissipation efficiency of the lamp housing, thereby improving the heat dissipation stability of the electric vehicle LED lamp housing.

[0022] 2. In this utility model, by pulling the pull block, the connecting rod and the limiting plate are driven to squeeze the reset spring. At this time, the locking pin moves with the limiting plate and is released from the restriction of the locking hole. Then the fixing plate can be removed from the lamp housing body, thereby achieving convenient disassembly for internal maintenance. This solves the problem of cumbersome disassembly and time-consuming and laborious maintenance of traditional lamp housings, and improves the convenience of maintenance and flexibility of use of electric vehicle LED lamp housings.

The cooling fan 7 is located on the side wall of the cooling fins 8 to force airflow and enhance the heat dissipation effect. The outer wall of the cooling fan 7 is fixedly connected to the inside of the fixing frame 4.

A magnet 9 is fixedly connected inside the fixing frame 4, and a magnet 10 is fixedly connected inside the dust filter 5. Magnets 9 and 10 attract each other and work together to fix the dust filter 5, achieving both quick removal and stable fixation.

[0035] Reference Figures 5-7The connecting components include a fixing ring 11, a locking block 12, and a slot 14 formed inside the fixing plate 3.

The outer wall of the locking block 12 is fixedly connected to the side wall of the fixing ring 11. The locking block 12 and the slot 14 engage to achieve initial fixation. A locking post 15 is slidably connected inside the fixing plate 3. A locking hole 13 is formed inside the locking block 12. The locking post 15 engages with the locking hole 13 and cooperates with the locking block 12 to perform locking movement, achieving the effect of quick installation and removal of the fixing plate 3.

[0036] Working principle: When the LED light starts working, the cooling fan 7 immediately starts, drawing outside air into the lamp housing through the dust filter 5. The dust filter 5 is fixed to the mounting frame 4 by the magnetic attraction of magnets 9 and 10, ensuring airtightness while filtering dust from the air. The drawn-in air flows over the surface of the heat dissipation fins 8, carrying away the heat generated by the LED light. The heat dissipation fins 8 are tightly connected to the mounting frame 4, ensuring that heat can be quickly conducted to the entire cooling system. When there is too much dust on the surface of the dust filter 5, it can be removed for cleaning by simply pulling it outward with the lever 6 to overcome the magnetic attraction, ensuring unobstructed airflow. When it is necessary to clean the internal components of the lamp housing... During maintenance, pulling the pull block 18 causes the connecting rod 17 to drive the limiting plate 16 to press the reset spring 19. The limiting plate 16 simultaneously drives the locking post 15 to move, causing the locking post 15 to disengage from the locking hole 13 on the locking block 12, thus releasing the restriction on the locking block 12. At this time, the fixing plate 3 separates from the fixing ring 11, and the fixing plate 3 can be removed from the lamp housing body 1 for easy inspection or replacement of internal LED lights, heat dissipation components, etc. After maintenance, the fixing plate 3 is reset, so that the locking block 12 is inserted into the locking slot 14. The pull block 18 is released, and the reset spring 19 pushes the limiting plate 16 to reset. The locking post 15 is reinserted into the locking hole 13, achieving a stable connection between the fixing plate 3 and the lamp housing body 1.
