Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a vehicle taillight assembly with a heat shield and a vehicle. Background Technology

[0002] As demands for vehicle headlight design and brightness increase, the power of internal heat-generating components in headlights is rising. Conversely, headlight space is shrinking, leading to increasingly poor heat dissipation and ineffective cooling. Furthermore, the demand for specialized headlight designs results in more complex and irregular headlight spaces, creating poorly ventilated cooling environments that are far from the heat source. This makes the headlights prone to fogging, negatively impacting their performance.

[0003] Current technologies for reducing headlight fogging typically involve using ventilation holes or breathable membranes to maintain internal and external air pressure balance and prevent moisture buildup. However, using only ventilation holes results in poorer heat dissipation for higher-power components. Using only breathable membranes can easily lead to rupture in harsh environments, damaging the internal structure of the headlight. Another approach is to add anti-fogging agent inside the roof, but this requires even spraying of the agent inside the headlight; excessive spraying can cause drips, and the anti-fogging agent requires high quality, resulting in higher production costs.

[0004] Therefore, in existing technologies, how to effectively prevent fogging inside vehicle lights in environments with large temperature differences and close proximity to heat sources is a technical problem that urgently needs to be solved. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a vehicle taillight assembly with a heat insulation cover and a vehicle. By improving the structure of the vehicle taillight, it can effectively prevent fogging inside the taillight even in environments with large temperature differences and close proximity to heat sources.

[0006] The present invention relates to a vehicle taillight assembly with a heat shield, comprising a taillight and a heat shield covering the taillight, wherein an air passage space is formed between the heat shield and the taillight, and air flows through the air passage space when the vehicle is moving.

[0007] Furthermore, the heat shield is isolated between the taillight and the vehicle exhaust pipe.

[0008] Furthermore, the taillight includes a lamp housing, and the heat insulation cover covers the lamp housing and forms the ventilation space between the heat insulation cover and the lamp housing; the lamp housing has a heat dissipation hole I that connects the interior of the lamp housing and the ventilation space.

[0009] Furthermore, a breathable membrane is covered on the heat dissipation hole I, and the breathable membrane is pressed onto the heat dissipation hole I by a pressure cap.

[0010] Furthermore, the pressure cap is detachably and fixedly connected to the lamp housing, and the pressure cap is provided with heat dissipation holes II.

[0011] Furthermore, the taillight assembly also includes a fixing member, and the heat shield is fixedly connected to the lamp housing through the fixing member. The heat shield is provided with a connecting hole for the fixing member to pass through, and the fixing member passes through the connecting hole and is fixedly connected to the lamp housing.

[0012] Furthermore, the heat insulation cover is covered with an aluminum film.

[0013] Furthermore, there are several heat dissipation holes I, which are evenly distributed, and the heat dissipation holes I and II are strip-shaped holes.

[0014] Furthermore, the length of heat dissipation hole I is 13mm to 15mm, and the width of heat dissipation hole I is 4mm to 5mm; the length of heat dissipation hole II is 36mm to 38mm, and the width of heat dissipation hole II is 8mm to 9mm.

[0015] The vehicle of this utility model includes the aforementioned vehicle taillight assembly with a heat shield.

[0016] The beneficial effects of this utility model are as follows: The vehicle taillight assembly with heat insulation cover of this utility model can isolate the heat from external heat sources by setting the heat insulation cover, thereby reducing the possibility of fogging inside the taillight. At the same time, it forms an air passage space, which is conducive to the air flow between the inside of the taillight and the outside, thereby further reducing the possibility of fogging inside the taillight. Moreover, the overall structure is simple and the production cost is low. Attached Figure Description

[0023] Figure 1This is a structural diagram of the rear taillight assembly with the heat shield concealed. Figure 2 for Figure 1 A schematic diagram of the structure when the heat shield is concealed. Figure 3 for Figure 1 A sectional view along the AA direction, as shown Figure 1-3 As shown: This embodiment of the vehicle taillight assembly with a heat shield includes a taillight and a heat shield 2 covering the taillight. An air passage space is formed between the heat shield 2 and the taillight, allowing airflow when the vehicle is moving. By providing the heat shield 2 over the taillight, heat from the vehicle's exhaust pipe can be isolated for certain vehicle models, thereby reducing the temperature difference between the inside and outside of the taillight while the vehicle is in motion. This reduces the possibility of fogging inside the taillight, preventing it from affecting its use. Simultaneously, the air passage space between the heat shield 2 and the taillight facilitates airflow between the taillight's interior and the external environment, promoting heat dissipation and further reducing the possibility of fogging. This makes the taillight assembly of this invention suitable for environments with large temperature differences and proximity to heat sources. Furthermore, its simple overall structure makes it easier to assemble compared to existing technologies, while also resulting in lower production costs.

[0024] In this embodiment, the heat shield 2 is positioned between the taillight and the vehicle's exhaust pipe. The heat shield 2 primarily isolates the heat from the vehicle's exhaust pipe during vehicle operation, thereby reducing the temperature difference between the inside and outside of the taillight.

[0025] In this embodiment, the taillight includes a lamp housing 1, and a heat shield 2 covers the lamp housing 1, forming an air passage space between them. The lamp housing 1 has a heat dissipation hole I3 connecting the interior of the lamp housing 1 to the air passage space. Taillights generally include a lamp housing 1, a lamp cover, and a light source, which is an application of existing technology and will not be described in detail here. The lamp housing 1 has several mounting parts 101 that connect to the vehicle body. The heat shield 2 has clearance openings corresponding to the mounting parts 101. The shape of the heat shield 2 is roughly adapted to the shape of the lamp housing 1. Of course, the size of the heat shield 2 is larger than the size of the lamp housing 1, thus forming an air passage space between the heat shield 2 and the lamp housing 1, and this air passage space is connected to the external environment. A heat dissipation hole I3 is provided on the lamp housing 1. There can be several heat dissipation holes I3, with at least four heat dissipation holes I3 forming a group, such as... Figure 1 As shown, the lamp housing 1 is provided with at least two sets of heat dissipation holes I3. Multiple sets can be provided as needed, so that the inside of the lamp housing 1 is connected with the air passage space, which is conducive to the heat dissipation inside the lamp housing 1 and reduces the possibility of taillight fogging.

[0026] In this embodiment, a breathable membrane 5 covers the heat dissipation hole I3, and the breathable membrane 5 is pressed onto the heat dissipation hole I3 by a pressure cap 4. The breathable membrane 5 can be made of materials such as polyethylene or polyurethane, which is an application of existing technology and will not be described in detail here. By setting the breathable membrane 5, air can flow between the inside of the lamp housing 1 and the ventilation space, while preventing external impurities, such as mud and sand, from entering the inside of the lamp housing 1 through the heat dissipation hole I3, thus preventing damage to the taillight. At the same time, the breathable membrane 5 is fixed by the pressure cap 4, which covers the breathable membrane 5, thereby protecting the breathable membrane 5 from damage.

[0027] In this embodiment, the pressure cover 4 is detachably fixed to the lamp housing 1, and the pressure cover 4 is provided with heat dissipation holes II 401. The pressure cover 4 is connected to the lamp housing 1 by self-tapping screws. By providing heat dissipation holes II 401 on the pressure cover 4, it can protect the breathable membrane 5 while communicating with the air passage space through the heat dissipation holes II 401.

[0028] In this embodiment, the taillight assembly further includes a fixing component. The heat shield 2 is fixedly connected to the lamp housing 1 via the fixing component. The heat shield 2 has a connecting hole for the fixing component to pass through. The fixing component passes through the connecting hole and is fixedly connected to the lamp housing 1. The fixing component is generally a bolt. The lamp housing 1 has multiple mounting points. The fixing component fixes the heat shield 2 to the lamp housing 1 through the mounting points one by one. The overall assembly structure is simple and reliable.

[0029] In this embodiment, the heat insulation cover 2 is covered with an aluminum film. Covering the heat insulation cover 2 with an aluminum film helps to further improve the heat insulation effect.

[0030] In this embodiment, there are several heat dissipation holes I3, which are evenly distributed. The heat dissipation holes I3 and the heat dissipation holes II 401 are strip-shaped holes. At least two sets of heat dissipation holes I3 are provided, and two pressure caps 4 are provided corresponding to the two sets of heat dissipation holes I3. Each pressure cap 4 has a corresponding heat dissipation hole II 401.

[0031] In this embodiment, the length of heat dissipation hole I3 is 13mm to 15mm, and the width of heat dissipation hole I3 is 4mm to 5mm; the length of heat dissipation hole II401 is 36mm to 38mm, and the width of heat dissipation hole II401 is 8mm to 9mm. In this structure, the length and width of heat dissipation hole I3 and heat dissipation hole II401 can be set according to usage requirements. Compared with heat dissipation holes in the prior art, by setting heat dissipation hole I3 to a larger size, it has a larger air permeability area, which is more conducive to heat dissipation.

[0032] The vehicle in this embodiment includes the aforementioned taillight assembly with a heat shield 2. In this structure, the vehicle can be an all-terrain vehicle or a motorcycle, etc. The taillight assembly with a heat shield 2 of this invention, by covering the lamp housing 1 with the heat shield 2, can minimize the impact of external heat sources on the interior of the taillight, reducing the possibility of fogging inside the taillight. Simultaneously, the large-sized heat dissipation vent Ⅰ3 further facilitates heat dissipation inside the taillight, allowing it to adapt to high-temperature and high-humidity environments, thus expanding the application scenarios of the taillight and making it suitable for more vehicle models.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
