Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a headlight heating aluminum block. Background Technology

[0002] Headlight heating blocks are heating elements specifically designed for automotive headlights. They are typically made of high-quality aluminum and utilize aluminum's excellent thermal conductivity to rapidly raise the internal temperature of the headlight through electric heating. This effectively prevents moisture from condensing inside the headlight, ensuring clear and bright illumination in all weather conditions. The heating blocks are compact, easy to install, and have good high-temperature and corrosion resistance, allowing for stable operation over extended periods and providing strong protection for nighttime driving safety.

[0003] The patent application CN220891976U discloses a car headlight with snow-melting function, including a lamp holder with several lighting fixtures installed inside. An aluminum block is provided on the frame of the lamp holder and can be detachably connected thereto. A heat dissipation aluminum base is provided on the side of the aluminum block facing away from the lamp holder and can be detachably connected thereto. Several high-temperature ceramic heating elements are embedded in the heat dissipation aluminum base. One end of the high-temperature ceramic heating element is connected to a temperature control module through an electric wire. This technology requires significant modifications to the internal structure of the headlight lamp holder, has a limited scope of application, and the various components and the blower are distributed inside the headlight lamp holder, occupying a large amount of internal space. Therefore, this technology still has some room for modification. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a headlight heating aluminum block to address the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a headlight heating aluminum block, comprising an aluminum block, characterized in that: the aluminum block includes an air outlet end and a connecting end disposed at the bottom of the air outlet end; the air outlet end includes a plurality of rectangular air outlet pipes disposed at the top of the connecting end; the top of the air outlet pipes is provided with an air outlet; the bottom of the connecting end is provided with a blower; a ceramic heating element is provided between the connecting end and the blower through a connecting structure; and a temperature sensor capable of linkage with the ceramic heating element is provided on one side of the blower through a fixing component.

[0006] By adopting the above technical solution, the blower and temperature sensor are integrated on the aluminum block. The air outlet is directly connected to the blower through the connecting end. The temperature sensor on one side of the blower is linked with the ceramic heating element on the connecting end. When the temperature sensor detects the corresponding temperature, it activates the ceramic heating element to heat. The heat emitted by the ceramic heating element is blown to the rectangular air outlet pipe through the blower at the bottom of the connecting end for heat energy transfer. This heating aluminum block integrates the air outlet pipe, blower, and ceramic heating element on the aluminum block, which greatly reduces the overall volume and does not occupy the internal space of the headlight assembly.

[0007] The aforementioned headlight heating aluminum block can be further configured as follows: the connecting structure includes a mounting plate disposed between the connecting end and the blower, the mounting plate is vertically provided with a plurality of connecting pieces, the ceramic heating element is fixedly connected to the connecting pieces, the bottom of the connecting end is provided with a through hole for the connecting pieces and the ceramic heating element to pass through, so that the ceramic heating element is placed in a rectangular air outlet pipe, the rectangular air outlet pipe is provided with a plurality of embedded grooves for the ceramic heating element to be embedded in, and a heat outlet groove communicating with the rectangular air outlet pipe is opened on one side of the embedded groove.

[0013] The aforementioned headlight heating aluminum block can be further configured such that: the mounting plate has connecting ears at both ends, and the connecting end, connecting ears, and fixing surface are all provided with threaded connecting holes; the connecting end, connecting ears, and fixing surface are connected by bolts, and the length of the bolts is greater than the length of the connecting holes, so that the mounting plate can be axially installed in the car headlight by the bolts.

[0014] By adopting the above technical solution, a bolt connection is set between the connecting end, connecting ear, and fixing surface, and the bolt length is ensured to be greater than the length of the connecting hole, so that the mounting plate can be firmly fixed in the car headlight without significantly modifying the internal structure of the headlight socket. The installation method is simple and quick, and it can be applied to most car lights, greatly enhancing the applicability of the product.

[0015] The aforementioned headlight heating aluminum block can be further configured such that: the blower has a first air outlet at one end facing the mounting plate, the connecting plate is located between the connecting pieces and has second air outlets on both sides of the connecting pieces, and the mounting plate is connected to the blower to make the first air outlet, the second air outlet, the through hole, and the rectangular air outlet pipe communicate with each other.

[0016] By adopting the above technical solution, the setting of the first and second air outlets, combined with the through holes and rectangular air outlet ducts, allows the airflow generated by the blower to be evenly distributed on the headlight surface, which helps to quickly remove fog and moisture from the headlight surface, improve heating efficiency and defogging speed, and ensure that the driver can maintain good visibility even in adverse weather conditions.

[0017] The aforementioned headlight heating aluminum block can be further configured such that: a fixing plate is vertically provided at the bottom of the mounting plate, the fixing plate and the mounting plate form a mounting groove for installing a blower, the blower has arc-shaped grooves at both ends, and fixing holes are provided in the arc-shaped grooves and the fixing plate.

[0018] Using the above technical solution, the installation groove limits the blower to the bottom of the installation plate. The blower has arc-shaped grooves at both ends. Both the arc-shaped grooves and the fixing plate have fixing holes for fixing the two. The arc-shaped grooves facilitate the connection of screws inside. If the length of the screw is greater than the length of the fixing hole, the blower can be fixed inside the headlight socket by the screw.

[0019] The beneficial effects of this utility model are: the air outlet pipe, blower and ceramic heating element are integrated on the aluminum block, which greatly reduces the overall volume and does not occupy the internal space of the headlight assembly. Attached Figure Description
