[0001] The present application relates to the automotive field, and in particular to a B-pillar assembly and a vehicle. Background Art

[0002] With the advancement of automotive technology, vehicle safety and comfort are receiving increasing attention. In high-end vehicles, the B-pillar assembly typically consists of glass and plastic components, with cameras mounted on the plastic components for the vehicle's assisted driving functions. The cameras capture image information through the imaging area (FOV) of the B-pillar glass. However, in winter, the glass FOV of the B-pillar assembly is prone to fogging and frost, resulting in blurred camera images and affecting vehicle safety and the driving experience.

[0003] Currently, some solutions on the market use electric heating modules to heat the exterior panels. However, this method requires additional power to the heating module to generate heat, which increases the vehicle's energy consumption. In addition, since the module is equivalent to a heating point, it cannot evenly heat the FOV area.

[0004] Therefore, how to efficiently defrost the imaging area of ​​the vehicle's B-pillar becomes a technical problem that needs to be solved in this application. Utility Model Content

[0034] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0035] The following disclosure provides many different embodiments or examples for implementing different structures of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0036] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0037] In order to solve the technical problem of defrosting the B-pillar FOV area in the prior art, the present application provides a B-pillar assembly that can achieve the effect of defrosting by directly heating the B-pillar glass through hot air from an air conditioner.

[0038] Figure 1 A B-pillar assembly provided in an embodiment of the present application includes a B-pillar glass 400 and a mounting plate 100 installed on the back of the B-pillar glass 400, an air inlet member 200 and an exhaust member 300 installed on the mounting plate 100, wherein the mounting plate 100 is installed with the B-pillar glass 400 through a sealing adhesive path 500 to form a chamber that can at least cover the imaging area (FOV); one end of the air inlet member 200 is connected to the chamber, and the other end is connected to a hot air source, and one end of the exhaust member 300 is connected to the chamber to relieve the pressure of the chamber.

[0039] Through this application, the vehicle heating system can deliver hot air through the air inlet 200 into the chamber covering the imaging area, thereby heating the B-pillar glass, preventing condensation on the glass surface, and directly heating the glass, greatly improving the efficiency of defrosting. Specifically, compared to the heating module in the prior art, the warm air used in this application can be heated by introducing warm air into the FOV area, avoiding the need for additional energy. Moreover, because the warm air flows in the FOV area, it can achieve a uniform heating effect.

[0040] In the technical solution of the present application, the sealing adhesive path 500 can be made of a material such as PU adhesive to bond the mounting plate 100 and the B-pillar glass. The adhesive path can be arranged around the contour of the mounting plate 100. Moreover, due to the thickness of the adhesive path itself, a relatively flat chamber is formed between the B-pillar glass 400, the mounting plate 100, and the sealing adhesive path 500. The chamber can cover the B-pillar glass in the FOV area. The hot air provided by the hot air source is introduced into the chamber through the air inlet member 200, so that the hot air can be evenly distributed in the chamber to heat the glass. Optionally, the hot air source can adopt an appropriate form to provide hot air.

[0041] In the technical solution of the present application, the hot air source is a vehicle heating system, wherein the vehicle floor heating system can provide hot air for the vehicle air conditioner or the vehicle engine.

[0042] Optionally, to further improve heating efficiency, the chamber exists only within the FOV area, so that the hot air only acts on the chamber, avoiding wasting heat energy in areas that do not require heating. To prevent excessive pressure in the chamber and ensure that the hot air flows smoothly into the chamber, an exhaust member 300 is provided. Excess hot air can be discharged from the chamber through the exhaust member, thereby relieving the chamber pressure and ensuring that the hot air can be smoothly delivered into the chamber during the air supply process to continuously heat the glass, thereby achieving the desired defrosting effect.

[0043] The air inlet member 200 and the exhaust member 300 can both be connected to the electronic control system of the vehicle, so that the device can be selectively started when defrosting is required.

[0044] In order to heat the glass more effectively, according to a preferred embodiment, Figures 3 to 5 As shown, the air inlet member 200 is installed on the back of the mounting plate 100, and the air inlet member 200 includes an air inlet 202 for connecting to the vehicle heating system and a plurality of air outlets 201, and the mounting plate 100 is provided with a plurality of air inlet holes 101 corresponding to the plurality of air outlets 201.

[0045] In the technical solution of the present application, the air inlet member 200 can be provided with a plurality of air outlets 201 on its surface, and the air inlet member 200 can be installed on the back of the mounting plate 100 by screws, bonding, snapping, etc. The mounting plate 100 is provided with a plurality of air inlet holes 101 that pass through it, and these air inlet holes 101 correspond to the air outlets 201, so that the hot air generated by the vehicle air conditioner can pass through the air inlet 202 and then enter the chamber from the air outlet 201. The air inlet 202 of the air inlet member 200 can be provided in an appropriate manner. For example, the air inlet 202 can be provided on the side of the air inlet member 200 that is away from the mounting plate 100; or the air inlet 202 can also be provided on the side wall of the air inlet member 200. Compared with providing the air inlet 202 on the back, the technical solution of providing the air inlet 202 on the side wall of the air inlet member 200 can make the thickness of the embodiment of the present application smaller, which is convenient for subsequent assembly and avoids interference.

[0046] Through the present application, multiple air outlets 201 allow hot air to enter the chamber in a dispersed manner, thereby evenly heating the FOV area of ​​the B-pillar glass. Furthermore, since the air inlet member 200 is mounted on the back of the mounting plate 100, the distance between the mounting plate 100 and the B-pillar glass 400 is not increased, thereby reducing the height of the chamber and making the chamber smaller in volume. It does not require too much hot air to fill the chamber, further improving heating efficiency.

[0047] In order to facilitate the alignment of the air outlet 201 with the air inlet 101, according to a preferred embodiment, as shown in FIG. Figure 4 and Figure 5 As shown, the air outlet 201 protrudes toward the B-pillar glass 400 to pass through the air inlet hole 101 .

[0048] In the technical solution of the present application, the inner edge of the air inlet member 200 may have an annular cavity 205 connected to the air outlet 201, and the air inlet member 200 may be provided with multiple air inlet ducts 206 connected to the annular cavity 205. The two ends of the air inlet ducts 206 are respectively connected to the air inlet 202 and the annular cavity 205, so that hot air is sent into the multiple air inlet ducts 206 through the air inlet 202, and then the hot air is evenly sent into the annular cavity 205, and then the hot air is sent into the cavity through the multiple air outlets 201. The air inlet hole 101 may have a diameter that is not less than the outer diameter of the air outlet 201, so that during the installation process, the air outlets 201 can be inserted into the air inlet hole 101 one by one, which is convenient for positioning.

[0049] In order to prevent the high temperature of the hot air sent out from the air outlet 201 from causing aging of the mounting plate 100, according to a preferred embodiment, as shown in FIG. Figure 3 and Figure 7As shown, a heat insulating pad 600 is provided on one side of the mounting plate 100 facing the B-pillar glass. The heat insulating pad 600 is provided with an opening corresponding to the air outlet 201 , and the end of the air outlet 201 protrudes from the heat insulating pad 600 .

[0050] In the technical solution of the present application, the thermal insulation pad 600 is provided with through holes corresponding to the air outlets 201 for the air to pass through, and the thermal insulation pad 600 at least covers the periphery of all the air inlet holes 101. Therefore, when hot air enters the chamber for defrosting, the hot air sent out from the air outlets 201 is blocked by the thermal insulation pad 600 and does not directly contact the mounting plate 100, thereby increasing the service life of the mounting plate 100 and not affecting the defrosting effect. Optionally, the thermal insulation pad 600 covers the chamber.

[0051] In order to prevent dust and other impurities in the hot air sent by the vehicle air conditioner from entering the chamber and causing the B-pillar glass to be contaminated, according to a preferred embodiment, as Figure 6 As shown, the air inlet 200 includes an air inlet 202 for connecting to the vehicle's heating system. The air inlet 202 is provided with a filter assembly 220. The filter assembly 220 can include a dust filter in the form of a filter mesh to completely cover the air inlet duct of the air inlet 202, thereby blocking dust, debris, etc. outside the air inlet 202 and preventing dust from entering the field of view (FOV) area and affecting the camera's imaging. The filter assembly 220 can be installed on the air inlet using any suitable method, such as bonding, threading, or screw connection, without limitation, as long as the filter assembly 220 completely covers the air inlet duct of the air inlet 202. Optionally, in addition to its dust filtering function, the filter assembly 220 can also have a drying function to filter out moisture. For example, the filter assembly 220 can also be provided with a drying element, such as a calcium chloride desiccant or a silica gel desiccant, to further prevent moisture in the duct from entering the FOV area. Among them, the drying component can be installed on the air inlet 202 by bonding or the like and then the dust filter component can be installed on the surface of the dust filter component, or the drying component can also be installed on the surface of the filter component, so that the dust filter component and the drying component form an integrated structure and are thus installed together at the air inlet 202, etc. There is no restriction here, as long as both the dust filter component and the drying component can cover the air inlet duct of the air inlet.

[0052] Through this application, dust and other impurities as well as water vapor in the hot air sent out by the air conditioner or engine can be filtered and dried by the filter component 220, thereby ensuring that the hot air entering the chamber is clean and dry, avoiding the B-pillar glass from being contaminated by impurities such as dust and water vapor, resulting in the camera being unable to shoot clearly.

[0053] According to a preferred embodiment, the mounting plate 100 is provided with an exhaust hole 102 , and the exhaust member 300 is mounted on the back side of the mounting plate 100 and connected to the exhaust hole 102 .

[0054] In the technical solution of the present application, the exhaust hole 102 is opened on the mounting plate 100 and is located in the chamber. The exhaust component 300 may include structures such as an exhaust pipe, wherein the exhaust pipe can at least be connected to the outside of the vehicle, thereby discharging excess air in the chamber to the outside of the vehicle.

[0055] In order to improve the utilization efficiency of hot gas, according to a preferred embodiment, as Figure 3 and Figure 7 As shown, the exhaust component 300 includes a three-way valve 301 connected to the exhaust hole 102, a first pipeline 302 connected to the interior of the vehicle, and a second pipeline 303 connected to the outside of the vehicle. The other two ends of the three-way valve 301 are respectively connected to the first pipeline 302 and the second pipeline 303.

[0056] In the technical solution of this application, three-way valve 301 can take an appropriate form, such as a solenoid valve, to facilitate control of the opening and closing of the airflow path. First pipe 302 can be connected to the vehicle's air conditioning or engine vents, allowing heated air from the chamber to enter the vehicle for heating. Second pipe 303 can directly exhaust the heated air from the chamber outside the vehicle. Three-way valve 301 allows for flexible control of the exhaust direction of heated air from the chamber, improving its efficient use.

[0057] In the technical solution of this application, camera 700 can be mounted on mounting plate 100 in any suitable manner. For example, mounting plate 100 can include a camera hole for camera 700 to capture images, allowing camera 700 to be mounted on the back of mounting plate 100, thereby reducing the overall thickness of the assembly and maintaining the volume of the chamber. Furthermore, camera 700 can be mounted anywhere within the chamber, as long as it does not affect the camera 700's ability to capture images within the imaging area FOV.

[0058] In order to improve the acquisition effect of the camera, according to a preferred embodiment, Figure 4 As shown, the air inlet member 200 includes a recessed portion 203 for avoiding the camera 700 , and the plurality of air outlets 201 are arranged around the recessed portion 203 .

[0059] In the technical solution of the present application, at least a portion of the camera 700 can be located in the recessed portion 203, and multiple air outlets 201 are arranged around the camera 700, thereby enabling faster defrosting of the B-pillar glass near the camera 700. To facilitate camera wiring, the air inlet 200 can be provided with a wire hole 204 that passes through the recessed portion 203. The wire hole 204 is not connected to the annular cavity 205, thereby facilitating the installation of the camera 700.

[0060] According to the present application, a vehicle is also proposed, characterized in that it includes the B-pillar assembly described in the above embodiment.

[0061] In the technical solution of the present application, the vehicle's heating system can be connected to the B-pillar assembly, so that the hot air sent out by the air conditioner or the engine can be sent into the chamber to heat the B-pillar glass, thereby performing a defrost operation on the B-pillar glass, avoiding condensation of water droplets on the glass surface affecting the imaging effect of the camera, and directly heating the B-pillar glass with hot air greatly improves the defrost effect.
