Detailed Implementation

[0021] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0022] The following is for reference. Figures 1-14 Describes a vehicle body assembly 100 according to an embodiment of this application.

[0023] According to an embodiment of this application, the vehicle body assembly 100 includes: a B-pillar lower trim panel 1 and a ventilation device 2. The B-pillar lower trim panel 1 is provided with an installation opening 101 that extends through the wall thickness direction. The ventilation device 2 is provided through the installation opening 101 and is installed at the B-pillar lower trim panel 1, so that the B-pillar lower trim panel 1 can supply air to the passenger compartment side through the ventilation device 2.

[0024] It should be noted that the vehicle body assembly 100 according to the embodiments of this application is applied to a vehicle, which has an air conditioning system. The air conditioning system can be used to supply air to the passenger compartment side to achieve temperature regulation of the passenger compartment. Among them, the aforementioned ventilation device 2 can be installed as the air outlet structure of the air conditioning system at the lower trim panel 1 of the B-pillar, so that air can be supplied from the lower trim panel 1 of the B-pillar to the passenger compartment side through the ventilation device 2.

[0025] In some embodiments of this application, the ventilation device 2 includes: a housing assembly 21, an air guide assembly 22, a baffle plate 23, and a drive assembly 24.

[0026] The shell assembly 21 forms a gas flow channel for gas circulation, and the shell assembly 21 is installed at the mounting port 101 to fix the shell assembly 21 to the lower trim panel 1 of the B-pillar.

[0027] Furthermore, the air guide component 22 is disposed within the gas flow channel, and the air guide component 22 is used to guide the airflow within the gas flow channel. Moreover, the position of the air guide component 22 within the gas flow channel is adjustable. Thus, by changing the position and orientation of the air guide component 22 within the gas channel, the air guide component 22 can guide the airflow in different directions to achieve adjustment of the air supply direction of the ventilation device 2, enabling the ventilation device 2 to meet various air supply needs and helping to improve the user experience (i.e., the occupants of the vehicle).

[0028] Combination Figure 7 and Figure 8As shown, the baffle plate 23 is rotatably disposed in the gas flow channel around the first axis, and the baffle plate 23 is located on the side of the air guide assembly 22 near the air inlet end of the shell assembly 21. The drive assembly 24 is disposed on the shell assembly 21 and is connected to the baffle plate 23. The drive assembly 24 is used to drive the baffle plate 23 to rotate around the first axis to adjust the position and attitude of the baffle plate 23 in the gas flow channel.

[0029] The baffle plate 23 is located on the air inlet side of the air guide assembly 22, so that the baffle plate 23 can be arranged in an area that avoids the air guide assembly 22, thereby preventing interference between the baffle plate 23 and the air guide assembly 22. The gas in the gas flow channel flows from the air inlet side to the air outlet side. That is to say, the baffle plate 23 is located on the upstream side of the air flow path of the air guide assembly 22. By driving the baffle plate 23 to rotate through the drive assembly 24, the angle of the baffle plate 23 blocking the shell assembly 21 at the air inlet port can be adjusted by rotating the baffle plate 23, thereby realizing the opening and closing adjustment of the gas flow channel at the air inlet.

[0030] It should be noted that currently, the lower B-pillar trim panel 1 of the vehicle is used only as a decorative component, resulting in a single function of the body assembly 100 and failing to fully utilize its role in controlling the in-vehicle environment. In related technologies, the ventilation structure of vehicles often suffers from incomplete closure and air leakage, thereby affecting the effectiveness of in-vehicle temperature control and the comfort of passengers.

[0031] In this application, a ventilation device 2 is integrated at the body assembly 100. The ventilation device 2 is fixed at the lower trim panel 1 of the B-pillar, so that air can be delivered to the passenger compartment side at the lower trim panel 1 of the B-pillar, which can meet the usage requirements of delivering air to the passenger compartment side at the B-pillar. Furthermore, the ventilation device 2 is provided with an air guide component 22 and a wind deflector 23. The air delivery direction can be adjusted by the air guide component 22 to meet the user's usage requirements for different air delivery directions. Moreover, the air flow channel can be selectively opened and closed by the wind deflector 23 to selectively deliver air to the passenger compartment side through the ventilation device 2.

[0032] In some embodiments of this application, the wind deflector 23 can be constructed as a rubber component. The rubber component has good structural strength and a certain deformation capacity, which is suitable for abutting against the wall of the shell assembly 21 when the gas flow channel is closed, so as to form a good seal between the wind deflector 23 and the shell assembly 21, thereby effectively preventing problems such as air leakage at the ventilation device 2, and helping to improve the driving experience of the driver and passengers.

[0033] In some embodiments of this application, the shell assembly 21 includes: a shell body 211 and a ventilation panel 212. The shell body 211 encloses and forms a gas flow channel. The ventilation panel 212 is connected to the air outlet of the shell body 211, and a vent 21201 is formed on the ventilation panel 212. The vent 21201 communicates and cooperates with the air outlet of the shell body 211, so that the airflow flowing through the gas flow channel can be discharged to the passenger compartment side through the vent 21201. The ventilation panel 212 is connected and fixed to the B-pillar lower trim panel 1, so that the ventilation device 2 can be fixed on the B-pillar lower trim panel 1 through the connection and cooperation between the ventilation panel 212 and the B-pillar lower trim panel 1.

[0034] It is understandable that the shell assembly 21 consists of at least two parts: the shell body 211 and the ventilation panel 212. This allows for a split design of the shell assembly 21, reducing the processing and manufacturing difficulty of the shell assembly 21. For example, the shell body 211 can be connected and fitted with the ventilation panel 212 first, and then the shell body 211 and the ventilation panel 212 can be assembled together at the B-pillar lower trim panel 1.

[0035] Combination Figure 4 , Figure 9 as well as Figure 10 As shown in a further embodiment of this application, the outer peripheral wall of the shell body 211 is provided with a shell snap-fit ​​portion, and the ventilation panel 212 is provided with a snap-fit ​​arm 2121 extending towards the air inlet side of the shell body 211. The snap-fit ​​arm 2121 is used to snap into the shell snap-fit ​​portion to snap and fix the ventilation panel 212 to the shell body 211. Thus, the shell body 211 and the ventilation panel 212 can be connected and fitted by snap-fit, which is simple and highly reliable. The snap-fit ​​arm 2121 is located on the surface of the ventilation panel 212 facing away from the passenger compartment, that is, the surface of the ventilation panel 212 facing the air inlet side of the shell body 211.

[0036] The housing snap-fit ​​portion is formed on the outer peripheral wall of the housing body 211, ensuring that it does not occupy the internal space of the gas flow channel and guaranteeing the smooth flow of air within the channel. This avoids the connection structure (such as the aforementioned housing snap-fit ​​portion) increasing the airflow resistance within the gas flow channel. Simultaneously, the snap-fit ​​arm 2121 can extend along the peripheral wall of the housing body 211 to engage with the housing snap-fit ​​portion via a plug-in connection, thereby reducing the difficulty of connecting the housing body 211 to the ventilation panel 212.

[0037] Combination Figure 4 , Figure 9 as well as Figure 10As shown, in a further embodiment of this application, the housing snap-fit ​​portion includes: a first snap-fit ​​portion 2111 and a second snap-fit ​​portion 2112. The first snap-fit ​​portion 2111 is disposed on the outer peripheral wall of the housing body 211, and the first snap-fit ​​portion 2111 and the outer peripheral wall of the housing body 211 define a first snap-fit ​​groove 2113. A snap-fit ​​arm 2121 can pass through the first snap-fit ​​groove 2113. The first snap-fit ​​portion 2111 is used to restrict the snap-fit ​​arm 2121 from moving away from the outer peripheral wall of the housing. The second snap-fit ​​portion 2112 is disposed on the outer peripheral wall of the housing body 211 on the side away from the first snap-fit ​​portion 2111 where the snap-fit ​​arm 2121 is inserted. The second snap-fit ​​portion 2112 is used to snap-fit ​​with the snap-fit ​​arm 2121 to restrict the snap-fit ​​arm 2121 from disengaging from the first snap-fit ​​groove 2113.

[0038] It is understandable that the snap-fit ​​arm 2121 is used to snap-fit ​​with the first snap-fit ​​part 2111 and the second snap-fit ​​part 2112 respectively, so as to achieve multiple snap-fits between the snap-fit ​​arm 2121 and the housing snap-fit ​​part, improve the connection reliability between the snap-fit ​​arm 2121 and the housing snap-fit ​​part, and help improve the assembly effect between the ventilation panel 212 and the housing body 211.

[0039] Specifically, the snap-fit ​​arm 2121 can be snapped into the first snap-fit ​​groove 2113 by means of plug-in engagement, and the first snap-fit ​​part 2111 can constrain the snap-fit ​​part that is snapped into the first snap-fit ​​groove 2113, so that the snap-fit ​​arm 2121 can be kept in a position close to the outer peripheral wall of the shell body 211.

[0040] Furthermore, the latching arm 2121, after passing through the first latching part 2111, can move further toward the second latching part 2112, and the second latching part 2112 can engage with the latching arm 2121 to restrict the movement of the latching arm 2121 toward the disengagement direction (the opposite direction of the latching arm 2121 inserting into the first latching groove 2113), thereby further improving the engagement effect between the latching arm 2121 and the housing latching part. By constraining the latching arm 2121 in multiple directions through the first latching part 2111 and the second latching part 2112, it helps to ensure the reliability of the connection between the ventilation panel 212 and the housing body 211.

[0041] In a further embodiment of this application, the first snap-fit ​​portion 2111 includes two snap-fit ​​structures arranged in an L-shape, and the openings of the two snap-fit ​​structures are arranged opposite to each other so as to form a first snap-fit ​​groove 2113 by the two snap-fit ​​structures surrounding the outer peripheral wall of the shell body 211.

[0042] Combination Figure 4 , Figure 9 as well as Figure 10As shown, in some embodiments of this application, the second snap-fit ​​portion 2112 includes a snap-fit ​​protrusion 2115. A guide rib 2116 is formed on the side of the snap-fit ​​protrusion 2115 opposite to the first snap-fit ​​portion 2111. The guide rib 2116 is used to guide the snap-fit ​​arm 2121 toward the peripheral wall side away from the shell body 211. After part of the snap-fit ​​arm 2121 passes through the guide rib 2116, the snap-fit ​​arm 2121 can move closer to the outer peripheral wall side of the shell body 211 under its own elasticity and the constraint of the first snap-fit ​​portion 2111, so as to realize the reset of the snap-fit ​​arm 2121.

[0043] Furthermore, there are two snap-fit ​​protrusions 2115, and each snap-fit ​​protrusion 2115 has a guide rib 2116 formed on the side facing the first snap-fit ​​part 2111. Thus, the snap-fit ​​arm 2121 can be guided by the two guide ribs 2116 at the same time, so that when the snap-fit ​​arm 2121 moves towards the snap-fit ​​protrusion 2115, it is supported by the guide rib 2116 to a position away from the outer peripheral wall of the shell body 211.

[0044] A second snap-fit ​​groove 2114 is formed between the two snap-fit ​​protrusions 2115. The snap-fit ​​arm 2121 snaps into and passes through the second snap-fit ​​groove 2114. A portion of the snap-fit ​​arm 2121 can snap onto the side of the snap-fit ​​protrusion 2115 opposite to the first snap-fit ​​portion 2111. The snap-fit ​​protrusion 2115 cooperates with this portion of the snap-fit ​​arm 2121 to prevent the snap-fit ​​arm 2121 from coming out, thereby improving the reliability of the cooperation between the snap-fit ​​arm 2121 and the snap-fit ​​portion of the housing.

[0045] Reference Figure 10 A clearance groove is formed at the snap-fit ​​arm 2121. The clearance groove is suitable for avoiding the snap-fit ​​protrusion 2115, so that when the snap-fit ​​arm 2121 is inserted into the preset position and re-deformed, it avoids the snap-fit ​​protrusion 2115 through the clearance groove.

[0046] Combination Figure 4 , Figure 9 as well as Figure 10 As shown, in some embodiments of this application, the snap-fit ​​arm 2121 includes a first plate segment 21211, a second plate segment 21212, and a third plate segment 21213 connected in sequence.

[0047] Furthermore, after the snap-fit ​​arm 2121 engages with the snap-fit ​​portion of the housing, the first plate segment 21211 is located on the side of the snap-fit ​​protrusion 2115 away from the first snap-fit ​​portion 2111. The aforementioned clearance groove is formed at the second plate segment 21212, and the second plate segment 21212 is embedded in the second snap-fit ​​groove 2114. The third plate segment 21213 has a large width and engages with the first snap-fit ​​groove 2113.

[0048] Understandably, during the engagement of the snap-fit ​​arm 2121 with the housing snap-fit ​​part, the first plate segment 21211 and the second plate segment 21212 are first inserted into the first snap-fit ​​part 2111. When the first plate segment 21211 is inserted into the guide rib 2116, under the guidance of the guide rib 2116, the snap-fit ​​arm 2121 deforms from one end of the first plate segment 21211 toward the outer peripheral wall away from the housing body 211. As the snap-fit ​​arm 2121 is further inserted, the first plate segment 21211 moves to the side of the snap-fit ​​protrusion 2115 away from the first snap-fit ​​part 2111. Under the elasticity of the snap-fit ​​arm 2121 itself and the constraint of the first snap-fit ​​part 2111 on the third plate segment 21213, it is reset. Moreover, the two snap-fit ​​protrusions 2115 are located on both sides of the second plate segment 21212. At this time, with the cooperation of the first plate segment 21211 and the snap-fit ​​protrusion 2115, the snap-fit ​​arm 2121 can be effectively prevented from coming out, and the first snap-fit ​​part 2111 can limit the third plate segment 21213 to further improve the snap-fit ​​reliability between the snap-fit ​​arm 2121 and the snap-fit ​​part of the housing.

[0049] In some embodiments of this application, a reinforcing rib 2122 is provided on the snap-fit ​​arm 2121. The reinforcing rib 2122 is provided on the side of the plate structure (i.e. the first plate segment 21211, the second plate segment 21212 and the third plate segment 21213) away from the outer peripheral wall of the shell body 211, so as to improve the structural strength of the snap-fit ​​arm 2121 through the reinforcing rib 2122 and avoid cracking and other problems during the snap-fit ​​of the snap-fit ​​arm 2121 with the shell snap-fit ​​part.

[0050] like Figure 2 As shown, in some embodiments of this application, the B-pillar lower trim panel 1 is provided with a recess 111 at the mounting opening 101. The recess 111 is recessed from the mounting opening 101 to the side away from the passenger compartment. At least part of the ventilation panel 212 is embedded in the recess 111, and the ventilation panel 212 is snapped to the bottom wall of the recess 111. Thus, the ventilation panel 212 and the B-pillar lower trim panel 1 can be connected and fixed by snap-fit ​​installation. The assembly method is simple and highly reliable.

[0051] Understandably, the recess 111 is the installation structure for the B-pillar lower trim panel 1 and the ventilation panel 212. The design of the recess 111 can improve the structural strength of the connection and mating area between the B-pillar lower trim panel 1 and the ventilation panel 212, thereby improving the installation reliability of the ventilation panel 212 at the B-pillar lower trim panel 1. Furthermore, the recess 111 structure can be used to accommodate part of the ventilation panel 212, thereby limiting the ventilation panel 212 in the circumferential direction through the peripheral wall of the recess 111. It can also reduce the size of the ventilation panel 212 protruding from the B-pillar lower trim panel 1, which helps to further improve the appearance consistency of the B-pillar lower trim panel 1 at the ventilation device 2.

[0052] It should be noted that the snap-fit ​​structure between the ventilation panel 212 and the recess 111 is not specifically limited here. It can be constructed as a snap fastener, a slot, a snap-fit ​​rib, a pin, etc., as long as it can satisfy the snap-fit ​​fixing between the ventilation panel 212 and the recess 111.

[0053] In some embodiments of this application, a support structure is provided on the back of the ventilation panel 212, and a panel felt 215 is provided at the support structure. The panel felt 215 can cooperate with the B-pillar lower trim panel 1 to provide support at the ventilation panel 212, so as to prevent the panel from deforming when the ventilation device 2 is adjusted by the air guide assembly 22.

[0054] In some embodiments of this application, the drive assembly 24 includes a dial 241, a drive crank 242, and a drive connecting rod 243.

[0055] The dial 241 is rotatably disposed on the outer circumferential side of the housing body 211 (i.e., the side of the housing body 211 away from the gas flow channel) around the central axis. The drive crank 242 is connected to the wind deflector 23 and is rotatably disposed on the outer circumferential side of the housing body 211 around a first axis, which is parallel to the axial direction of the dial 241. The drive linkage 243 is connected between the dial 241 and the drive crank 242, so that one end of the drive linkage 243 is pivotally connected to the dial 241 and the other end of the drive linkage 243 is connected to the drive crank 242.

[0056] It should be noted that the dial 241 can be constructed as a hollow annular structure. A locking seat 214 is provided on the outer peripheral wall of the housing body 211. The locking seat 214 is used to engage with the dial 241 to achieve assembly of the dial 241 on the housing body 211. At the same time, after the dial 241 engages with the locking seat 214, the locking seat 214 can provide rolling support for the hollow wall of the dial 241 to improve the stability of the dial 241 during rolling.

[0057] Therefore, the user can drive the drive linkage 243 to move through the wave dial 241, and further drive the drive crank 242 to swing through the drive linkage 243, thereby driving the baffle 23 to rotate around the first axis through the drive crank 242, realizing the position adjustment of the baffle 23 in the gas flow channel, and then realizing the opening and closing control of the gas flow channel by adjusting the position of the baffle 23. The adjustment method is simple and highly reliable.

[0058] In a further embodiment of this application, the dial 241 is disposed through the ventilation panel 212, allowing the user to manually operate the dial 241 from the side of the passenger compartment, which is convenient for the user to operate.

[0059] In some embodiments of this application, the drive assembly 24 further includes a dial trim 244, which is fixedly connected to the dial 241 by a snap-fit ​​connection. The dial trim 244 is used for user operation, allowing the user's driving force to be fed back to the dial 241 through the dial trim 244. The dial trim 244 is provided with friction stripes to increase friction during operation and improve the user experience.

[0060] Combination Figure 5 and Figure 6 As shown, in some embodiments of this application, the outer peripheral wall of the shell body 211 is provided with a limiting boss 213, which is used to limit the rotation of the drive crank 242. This limiting boss 213, in conjunction with the drive crank 242, positions the movement stroke of the baffle 23, facilitating its retention in the closed position and preventing excessive deflection of the drive crank 242 that could open the gas flow channel. This assists the user in operating the drive assembly 24, making it easier to adjust and position the baffle 23 in the closed position, effectively preventing air leakage when the ventilation device 2 is closed.

[0061] Reference Figure 11 As shown, in some embodiments of this application, the air guide component 22 includes: a first air guide component 221 and a second air guide component 222.

[0062] The first air guiding assembly 221 includes multiple first air guiding plates 2211 and a first connecting rod 2212. Each first air guiding plate 2211 is rotatably mounted on the shell body 211, and the multiple first air guiding plates 2211 are respectively connected to the first connecting rod 2212. The rotation axis of each first air guiding plate 2211 is perpendicular to the arrangement direction of the multiple first air guiding plates 2211. The second air guiding assembly 222 includes multiple second air guiding plates 2221 and a second connecting rod 2222. Each first air guiding plate 2211 is rotatably mounted on the shell body 211, and the multiple second air guiding plates 2221 are respectively connected to the second connecting rod 2222. An adjusting paddle 223 is sleeved on a second air guiding plate 2221 and is used to drive the second air guiding plate 2221 to rotate. The adjusting paddle 223 is connected to a first air guiding plate 2211 and can slide along the extension direction of the second air guiding plate 2221 to drive the first air guiding plate 2211 to rotate.

[0063] It is understood that in the first air guide assembly 221, multiple first air guide plates 2211 are rotatably mounted on the shell body 211, and the rotation axes of the multiple first air guide plates 2211 are coplanar. Since the multiple first air guide plates 2211 are all connected and engaged with the first connecting rod 2212, the connection and engagement position between the first connecting rod 2212 and the first air guide plate 2211 is eccentrically set relative to the rotation axes of the multiple first air guide plates 2211. Thus, when one first air guide plate 2211 rotates, the other first air guide plates 2211 can be driven to rotate synchronously through the first connecting rod 2212, thereby achieving synchronous adjustment of the multiple first air guide plates 2211. Similarly, in the second air guide assembly 222, multiple second air guide plates 2221 are rotatably mounted on the shell body 211, and the rotation axes of the multiple second air guide plates 2221 are coplanar. Since the multiple second air guide plates 2221 are all connected and cooperated with the second connecting rod 2222, the connection and cooperation position between the second connecting rod 2222 and the second air guide plate 2221 is eccentrically set relative to the rotation axes of the multiple second air guide plates 2221. Thus, when one second air guide plate 2221 rotates, the other second air guide plates 2221 can be driven to rotate synchronously through the second connecting rod 2222, thereby realizing the synchronous adjustment of the multiple second air guide plates 2221.

[0064] The extension direction of the first air guide plate 2211 intersects with the extension direction of the second air guide plate 2221, thereby improving the air guiding effect of the air guide assembly 22 on the airflow, so that the air guide assembly 22 can guide the airflow in multiple directions to better meet the user's needs.

[0065] Understandably, when it is necessary to adjust the deflection angle of the second air guide plate 2221, one of the second air guide plates 2221 can be deflected by moving the adjusting lever 223, and the other second air guide plates 2221 can be rotated synchronously through the second connecting rod 2222, so as to achieve synchronous adjustment of the deflection angle of multiple second air guide plates 2221; when it is necessary to adjust the deflection angle of the first air guide plate 2211, the position of the adjusting lever 223 on the second air guide plate 2221 can be adjusted by sliding the adjusting lever 223, and the first air guide plate 2211 connected to it can be deflected by the adjusting lever 223, so as to achieve adjustment of the deflection angle of the first air guide plate 2211. The other multiple first air guide plates 2211 are synchronously deflected and adjusted with the first air guide plate 2211 (i.e. the first air guide plate 2211 connected to the sliding lever) under the action of the first connecting rod 2212. Therefore, the first air guide assembly 221 and the second air guide assembly 222 can be adjusted respectively by driving the adjustment lever 223, and the adjustment method is simple and highly reliable.

[0066] In some embodiments of this application, the ventilation panel 212 is provided with a positioning pin 2123 on the side surface opposite to the passenger compartment. The positioning pin 2123 is used to position and cooperate with the shell body 211 to further improve the positioning effect between the ventilation panel 212 and the shell body 211, so that the connection between the ventilation panel 212 and the shell body 211 is highly reliable.

[0067] In some embodiments of this application, the shell assembly 21 further includes an overlay 2161 and a foam 2162. The overlay 2161 can cover the windshield 23, and the foam 2162 is disposed on the shell body 211 and surrounds the outer peripheral wall of the shell body 211.

[0068] When the wind deflector 23 is in the closed state, the rubber coating 2161 can abut against the inner wall surface of the shell body 211 to seal it, thereby achieving the closure of the shell body 211 on the air inlet side.

[0069] In some embodiments of this application, the lower B-pillar trim panel 1 includes a lower trim panel body 11 and a lower trim panel skin 12. The lower trim panel body 11 and the lower trim panel skin 12 are connected, and the lower trim panel skin 12 is located on the side surface of the lower trim panel body 11 facing the passenger compartment, so as to shield and protect the lower trim panel body 11 through the lower trim panel skin 12 and improve the appearance of the lower B-pillar trim panel 1.

[0070] In a further embodiment of this application, the lower B-pillar trim panel 1 further includes a lower trim panel sound-absorbing cotton 13, which is disposed on the side of the lower trim panel body 11 facing away from the passenger compartment and is used for sound absorption and noise reduction. The lower trim panel sound-absorbing cotton 13 can be fixed to the lower trim panel body 11 by adhesive bonding.
