Description

Technical Field

[0001] This invention relates to the field of vehicles, and more particularly to a vehicle windshield support assembly. Background Technology

[0002] In autonomous driving technology, information acquisition elements such as sensors and cameras are typically mounted on the windshield to collect real-time environmental information ahead of the vehicle, providing decision-making support for the autonomous driving system. To ensure stable sensor mounting, existing technologies usually employ bracket assemblies to fix them to the windshield. To ensure the sensors can clearly and unobstructedly perceive the forward field of view, the bracket assembly also integrates a heating structure and an anti-glare layer. The heating structure heats and defogs the area on the windshield corresponding to the sensor, preventing a decrease in light transmittance due to condensation on the glass surface. The anti-glare layer suppresses light reflection, preventing reflected light from entering the sensor head and interfering with its normal recognition of the forward environment.

[0003] However, in existing technologies, a large amount of adhesive is used when the various layers of the heating structure are laminated, and adhesive is also used to bond the heating structure to the support. Therefore, during prolonged use, this adhesive easily releases a large amount of volatile substances. These volatile substances diffuse unimpeded into the optical path of the information acquisition element, and then adhere to the sensing surface or optical path of the information acquisition element, adversely affecting the detection accuracy and response reliability of the information acquisition element. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a vehicle windshield bracket assembly that effectively prevents volatiles generated by the heat-generating structure from entering the optical path of the information acquisition element, thereby enabling the information acquisition element to operate effectively and stably.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A vehicle windshield bracket assembly, characterized in that it includes a base, a heating structure, and a metal-sealed heat-conducting cover; The front of the base is mounted on the windshield of the vehicle. The front of the base has a recessed area through which the light path of the information acquisition element passes to acquire environmental information in front of the vehicle. The metal-sealed heat-conducting cover is disposed on the inner surface of the recessed area, and an anti-glare layer is provided on the front of the metal-sealed heat-conducting cover facing the windshield. The heating structure is located between the inner surface of the recessed area and the back of the metal-sealed heat-conducting cover. The metal-sealed heat-conducting cover fully covers the heating structure and isolates the heating structure from the optical path of the information acquisition element.

[0006] Preferably, the base includes a mounting bracket and a heat-insulating tray located on the front of the mounting bracket, and the recessed area is formed by the heat-insulating tray.

[0007] Preferably, the shape of the metal-sealed heat-conducting cover is a contoured structure of the inner surface of the recessed area.

[0008] Preferably, the back of the metal-sealed heat-conducting cover has a groove for accommodating the heat-generating structure.

[0009] Preferably, the metal-sealed heat-conducting cover is an aluminum-sealed heat-conducting cover, a copper-sealed heat-conducting cover, or a silver-sealed heat-conducting cover.

[0010] Preferably, a heat-conducting radiation layer is also provided between the metal-sealed heat-conducting cover and the anti-glare layer.

[0011] Preferably, the metal-sealed heat-conducting cover undergoes volatile pretreatment after the anti-glare layer is set, or the metal-sealed heat-conducting cover undergoes volatile pretreatment after the heat-conducting radiation layer and the anti-glare layer are set.

[0012] Preferably, the anti-glare layer is a carbon nanotube ultra-black coating, an inorganic ultra-black film, an inorganic graphene ultra-black coating, or a flocking layer.

[0013] Preferably, the base is provided with an exhaust assembly that connects the recessed area with the space on the back of the base.

[0014] The advantages of this invention are: 1. By setting up a metal-sealed heat-conducting cover that does not generate volatiles, the structure that generates a lot of heat from volatiles is completely blocked, effectively preventing the volatiles from the heat-generating structure from entering the optical path of the information acquisition element.

[0015] 2. After applying the appropriate coating to the front of the metal-sealed heat-conducting cover, high-temperature volatile pretreatment is carried out. This can fully pre-evaporate the volatiles that may exist in the heat-conducting radiation layer and the anti-glare layer, so that the volatiles can be further reduced or even zeroed out during later use, thus avoiding the impact on the information acquisition components.

[0016] 3. During assembly, the heat-conducting radiation layer and the anti-glare layer can be placed sequentially on the front of the metal-sealed heat-conducting cover, and then the heating structure can be attached to the back of the metal-sealed cover. Finally, the metal-sealed heat-conducting cover can be placed over the recessed area, which is convenient for assembly. Attached Figure Description

[0017] Figure 1 This is an exploded view of the vehicle windshield bracket assembly provided in this embodiment. Detailed Implementation

[0018] Combination Figure 1 The present invention provides a further description of the vehicle windshield bracket assembly.

[0019] A vehicle windshield bracket assembly is used to mount information acquisition elements, such as cameras and sensors, onto the windshield of an automobile, enabling the information acquisition elements to collect environmental information in front of the vehicle. Its features include a base 1, a heating structure 2, and a metal-sealed heat-conducting cover 3.

[0020] The base 1 has a recessed area 121 on its front side. The other parts of the front side of the base 1, excluding the recessed area 121, conform to the shape of the windshield surface for attachment and fixation onto the windshield. Simultaneously, the opening edge of the recessed area 121 corresponds to and fits into the windshield, forming a sealed space. An information acquisition element is disposed on the rear wall 16 of the recessed area 121 opposite the windshield, allowing the sensing end of the information acquisition element to collect environmental information in front of the vehicle through the recessed area 121 and the windshield.

[0021] The metal-sealed heat-conducting cover 3 is disposed on the inner surface of the recessed area 121. An anti-glare layer 5 is provided on the front side of the metal-sealed heat-conducting cover 3 facing the windshield. The anti-glare layer 5 completely covers the front side of the metal-sealed heat-conducting cover 3, and serves to absorb light and prevent glare.

[0022] The heating structure 2 is located between the inner surface of the recessed area 121 and the back of the metal-sealed heat-conducting cover 3. The heat generated by the heating structure 2 is transferred through the metal-sealed heat-conducting cover 3 to the corresponding part of the windshield and the recessed area 121, removing water vapor. The heating structure 2 can use existing materials such as carbon fiber heating cloth or electric heating wire, which can be purchased and used directly from the market. The edge contour dimension of the metal-sealed heat-conducting cover 3 is larger than the edge contour dimension of the heating structure 2, so that the metal-sealed heat-conducting cover 3 completely covers the heating structure 2. That is, the back of the metal-sealed heat-conducting cover 3, together with the inner surface of the recessed area 121, seals the heating structure 2, separating the heating structure 2 from the optical path of the information acquisition element, so that the volatiles generated by the heating structure 2 cannot enter the optical path of the information acquisition element.

[0023] The anti-glare layer 5 is preferably any one of an inorganic ultra-black coating, a carbon nanotube ultra-black coating, or an inorganic graphene ultra-black coating, which emits very few or no volatiles at 110°C. Alternatively, it can be a flocked layer. Inorganic ultra-black coatings, carbon nanotube ultra-black coatings, or inorganic graphene ultra-black coatings are all existing technologies and can be directly purchased and used commercially. Their characteristic of emitting very few or no volatiles at 110°C is their low volatile content. The flocked layer is an optical-specific low-release flocking layer, and the amount of volatiles generated during long-term use is far lower than that generated by the heating structure, resulting in minimal impact on the information acquisition element.

[0024] Since the metal-sealed heat-conducting cover 3 is made of metal, it possesses strong structural strength, high-temperature resistance, and is an independent component. Therefore, after the anti-glare layer 5 is installed, it undergoes volatile pretreatment. This involves baking at 140℃~160℃ for 30 to 60 minutes to fully volatilize any volatiles that may be present in the anti-glare layer 5, further reducing the amount of volatiles generated during subsequent use or even ensuring zero volatilization. When the anti-glare layer 5 is a flocked layer, the pretreatment of volatiles after the flocked layer is placed on the metal-sealed heat-conducting cover can further reduce the amount of volatiles generated during later use, even achieving zero volatilization, without affecting the normal operation of the information acquisition element.

[0025] The base 1 includes a mounting bracket 11 and a heat insulation tray 12 located on the front of the mounting bracket 11. The recessed area 121 is formed by the heat insulation tray 12. A sealing ring extending around the recessed area 121 is provided on the top surface of the heat insulation tray 12 facing the windshield. When the base 1 is attached to the windshield, the heat insulation tray 12 is tightly attached to the windshield through the sealing ring, so that the recessed area 121 and the windshield cooperate to form a sealed space.

[0026] The installation structure of the sealing ring on the heat insulation tray 12 is as follows: a groove is arranged in a ring recessed area 121 on the top surface of the heat insulation tray 12. The sealing ring is directly engaged in the groove, and then part of it is exposed outside the groove.

[0027] In some embodiments, the mounting bracket 11 and the heat insulation tray 12 are separate structures, so that the heat insulation tray 12 plastic part with its own heat insulation function can be manufactured separately. In a specific structure, the front of the mounting bracket 11 has a conformal mounting opening for the heat insulation tray 12, and the heat insulation tray 12 is fixed in the conformal mounting opening by adhesive or bolt connection. The adhesive method involves forming multiple connecting edges on the outer side wall 15 of the heat insulation tray 12, and after applying glue to the upper surface of the connecting edges, it can be pasted to the back of the mounting bracket 11 to fix the heat insulation tray 12 in the mounting opening.

[0028] In some other embodiments, the mounting bracket 11 and the heat insulation tray 12 are an integral structure, with the heat insulation tray 12 formed by a downward indentation of a local portion on the front of the mounting bracket 11.

[0029] The heat insulation tray 12 has a specific structure including a bottom wall 14, side walls 15 located on the left and right sides of the bottom wall 14, and a rear wall 16 located behind the bottom wall 14. The recessed area 121 is formed by the bottom wall 14, side walls 15, and rear wall 16. The rear wall 16 has a mounting hole 17, in which the sensing end of the information acquisition element is fixed and forms a sealing structure with the mounting hole 17.

[0030] The metal-sealed heat-conducting cover 3 is shaped like the inner surface of the recessed area 121 and covers the inner surface of the recessed area. Specifically, the metal-sealed heat-conducting cover 3 also has a corresponding base plate 33, side plates 32 located on the left and right sides of the base plate 33, and a rear plate 31 located behind the base plate 33. When the metal-sealed heat-conducting cover 3 is placed on the inner surface of the recessed area 121, the base plate 33 is attached to the bottom wall 14, the side plates 32 are attached to the side walls 15, and the rear plate 31 is attached to the rear wall 16, so that the metal-sealed heat-conducting cover 3 covers and shields most of the inner surface of the recessed area 121, further reducing the amount of volatiles that may be generated by the base 1 from entering the sealed space.

[0031] As a preferred embodiment, when the metal-sealed heat-conducting cover 3 is installed in the recessed area 121, the opening of the metal-sealed heat-conducting cover 3 is recessed by 0 to 2 mm relative to the opening of the recessed area 121, that is, the opening of the metal-sealed heat-conducting cover 3 is in contact with the windshield, or the maximum distance is 2 mm, so that the metal-sealed heat-conducting cover 3 covers and shields most of the inner surface of the recessed area 121.

[0032] The back of the metal-sealed heat-conducting cover 3 has a groove to accommodate the heating structure 2. During assembly, the heating structure 2 is first attached to the groove by adhesive, and then the metal-sealed heat-conducting cover 3 is placed on the inner surface of the recessed area 121. The groove and the inner surface of the heat insulation tray 12 cooperate to form a sealed area, completely sealing the heating structure 2.

[0033] The groove is on the back of the base plate 33, so that the heating structure 2 can be completely accommodated in the groove on the back of the base plate 33.

[0034] The depth of the groove is greater than the thickness of the heating structure 2, which isolates the heating structure 2 from the inner surface of the heat insulation tray 12, thus achieving an air insulation effect.

[0035] In some other embodiments, the heating structure 2 may also contact the heat-insulating tray 12.

[0036] The preferred method for installing the metal-sealed heat-conducting cover 3 on the inner surface of the recessed area 121 is to apply adhesive to the non-recessed area on the back of the metal-sealed heat-conducting cover 3 and then attach it to the inner surface of the recessed area 121 with adhesive.

[0037] In some other embodiments, L-shaped retaining feet 122 are provided on the top of the two sidewalls 15, which can press the top of the metal sealing heat conduction cover 3 so that the metal sealing heat conduction cover is positioned in the recessed area.

[0038] The metal-sealed heat-conducting cover 3 is preferably an aluminum-sealed heat-conducting cover with good thermal conductivity and low cost. Alternatively, it can be a copper-sealed heat-conducting cover, a silver-sealed heat-conducting cover, or other alloy-sealed heat-conducting structures with good thermal conductivity.

[0039] A heat-conducting radiation layer 4 is also provided on the surface of the metal-sealed heat-conducting cover 3 facing the windshield, and this heat-conducting radiation layer 4 is located on the back of the anti-glare layer 5. This radiative heat-conducting layer is a graphene heat-conducting layer or a carbon nanotube heat-conducting layer. Through this graphene heat-conducting layer or carbon nanotube heat-conducting layer, more than 90% of the heat on the metal-sealed heat-conducting cover 3 can be conducted and radiated to the enclosed space and the windshield.

[0040] The graphene thermal conductive layer and the carbon nanotube thermal conductive layer are almost non-volatile at 110℃, so they will not affect the operation of the information acquisition element.

[0041] Similarly, after the thermal radiation layer 4 and the anti-glare layer 5 are successively installed, the metal-sealed heat-conducting cover 3 undergoes volatile pretreatment. This involves baking at 140℃~160℃ for 30 to 60 minutes to fully volatilize any trace volatiles that may exist in the thermal radiation layer 4 and the anti-glare layer 5, thereby further reducing the amount of volatiles generated during subsequent use or further ensuring zero volatilization.

[0042] The base 1 is provided with an exhaust assembly (not shown in the attached figure) that connects the recessed area 121 to the back area of ​​the base 1. When heated, the air in the sealed space formed by the recessed area 121 and the windshield expands, and the exhaust assembly can perform the function of venting, thereby improving the safety of use.

[0043] The heat insulation tray 12, the heating structure 2, and the metal sealing heat conduction cover 3 are provided with corresponding mounting holes. The exhaust component is a miniature spring-type one-way valve. The miniature spring-type one-way valve is installed in the mounting hole to connect the sealed space with the back space of the base 1 in one direction. When the air in the sealed space is heated, it can be discharged through the miniature spring-type one-way valve. At the same time, it can also discharge the moisture in the sealed space to the outside, while the outside air cannot enter the recessed area 121.
