Description

Technical Field

[0001] The invention relates to the technical field of automobile parts manufacturing, and in particular to an automobile B-pillar. Background Art

[0002] The left and right sides of the car are usually provided with front, middle and rear connecting pillars connected between the car body and the roof to support the roof, wherein the front pillar is usually called the A pillar, the middle pillar is usually called the B pillar, and the rear pillar is usually called the C pillar. It is understandable that since the B pillar is located at the connection point between the front door and the rear door, and the door is provided with a liftable window, the existing B pillars usually include a rear B pillar fixedly connected between the middle of the car body and the roof, and a front B pillar as part of the front door window frame, wherein the rear door is rotatably connected to the rear B pillar. When the front door is closed, the front B pillar and the rear B pillar are combined into a B pillar.

[0003] However, the existing automobile B-pillar structure has the following technical defects: First, since the B-pillar includes the rear B-pillar and the front B-pillar, its structure is relatively complex, with many assembly processes and high manufacturing costs, and it is easy to produce an ugly joint between the front B-pillar and the rear B-pillar. For this reason, some people have designed a frameless (front) window, which can omit the front B-pillar. When the front window glass is raised, it forms a sealed connection with the sealing strips set on the roof, A-pillar, and front B-pillar. However, this type of frameless window still has a fatal defect. Since the front window glass and the sealing strip are respectively set on different component assemblies, the sealing effect is poor and it is easy to leak. Summary of the invention

[0004] The purpose of the present invention is to provide a car B-pillar, which can effectively simplify the structure and assembly procedures, reduce manufacturing costs, improve the aesthetics of the B-pillar, and effectively improve the sealing effect of the front window.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A B-pillar of an automobile is fixedly connected between a roof and a middle part of a vehicle body, a rear door is rotatably connected to the rear side of the B-pillar, and includes a sealing strip for sealing a front window glass, wherein the sealing strip includes a rear sealing strip arranged on the front side of the B-pillar, and the rear sealing strip is associated with a power mechanism including a controller, so that the rear sealing strip is movably arranged on the front side of the B-pillar, and the moving direction of the rear sealing strip forms an angle of 5°-10° with the front window glass raised to the rear sealing strip, and the power mechanism includes a linkage switch arranged on the inner side of the front door, and a position sensor for detecting the position of the front window glass, and the linkage switch includes a "raise" and "lower" button that can be activated in an inching manner. Control position, when the "up" control position is pressed, the front window glass rises, and the controller causes the rear sealing strip located in the B-pillar to move out synchronously to the first position close to the front window glass, thereby achieving primary sealing of the front window glass; when the front window glass is raised to position, the position sensor outputs an electrical signal to the controller, and the controller causes the rear sealing strip to move completely out to the second position, thereby achieving secondary sealing of the front window glass; when the "down" control position is pressed, the front window glass drops, and the controller causes the rear sealing strip to move backward synchronously to the first position; when the front window glass drops into the front door, the position sensor outputs an electrical signal to the controller, and the controller causes the rear sealing strip to move backward to the inside of the B-pillar.

[0007] The present invention arranges a rear sealing strip on the front side of the B-pillar, so that it can be separated from the front window glass arranged in the front door, thereby forming a frameless (front) window. That is to say, the B-pillar does not need to include a rear B-pillar connected between the roof and the middle part of the body and a front B-pillar as a part of the front door frame, which can effectively simplify the B-pillar structure and assembly procedures, reduce manufacturing costs, and is conducive to improving the aesthetics of the B-pillar.

[0008] In addition, the rear sealing strip is associated with a power mechanism including a controller, so that the rear sealing strip is movably arranged on the front side of the B-pillar. In particular, the moving direction of the rear sealing strip forms an angle of 5°-10° with the front window glass raised to the rear sealing strip, so that when the rear sealing strip is located in the B-pillar, even if the front window glass rises, no interference will occur. When it rains and the front window glass needs to be raised, the "up" control position of the linkage switch can be pressed. At this time, the front window glass is easily raised, and the controller causes the rear sealing strip located in the B-pillar to be synchronously moved out to the first position close to the front window glass, thereby achieving the primary sealing of the front window glass. That is to say, in this process, the rear sealing strip is only close to the front window glass to achieve the preliminary primary sealing of the front window glass, and then facilitate the raising of the front window glass; when the front window glass is raised to the position, the position sensor outputs an electrical signal to the controller, and the controller causes the rear sealing strip to be completely moved out to the second position, thereby achieving the secondary sealing of the front window glass. That is to say, only when it reaches the second position, the rear sealing strip will be tightly attached to the front window glass, thereby realizing the final secondary sealing of the front window glass; when the front window glass needs to be lowered, the "down" control position of the linkage switch can be pressed. At this time, the front window glass is lowered, and the controller makes the rear sealing strip move backward to the first position synchronously to facilitate the lowering of the front window glass and avoid severe friction between the front window glass and the rear sealing strip; when the front window glass is lowered into the front door, the position sensor outputs an electrical signal to the controller, and the controller moves the rear sealing strip backward to the inside of the B-pillar.

[0009] That is to say, the degree of adhesion between the rear sealing strip of the present invention and the front window glass varies under different conditions, which is beneficial to both improving the sealing effect and reducing the wear of the rear sealing strip.

[0010] It should be noted that for frameless (front) windows, we can use a similar structure to the B-pillar to set up the sealing structure between the front window glass, A-pillar, and roof. In addition, when the front window glass needs to be lowered and the "lower" control position of the linkage switch is pressed, the rear sealing strip can be retracted first, and then the front window glass can be lowered to effectively avoid friction between the front window glass and the rear sealing strip.

[0011] Preferably, the rear sealing strip includes an inner sealing strip and an outer sealing strip. When the rear sealing strip moves outward, the moving direction of the inner sealing strip is inclined from inside to outside, and the moving direction of the outer sealing strip is inclined from outside to inside, thereby clamping the front window glass between the inner sealing strip and the outer sealing strip.

[0012] Since the rear sealing strip includes an inner sealing strip and an outer sealing strip, and when the rear sealing strip moves outward, the moving direction of the inner sealing strip is inclined from the inside to the outside, and the moving direction of the outer sealing strip is inclined from the outside to the inside, so that the front window glass is sandwiched between the inner sealing strip and the outer sealing strip. In other words, when the rear sealing strip is located inside the B-pillar, the distance between the inner sealing strip and the outer sealing strip can be greater than the thickness of the front window glass, thereby ensuring the smooth rise of the front window glass.

[0013] Preferably, when the "up" control position is pressed, the front window glass rises, and the controller causes the inner sealing strip located in the B-pillar to be synchronously moved out to a first position against the front window glass, thereby achieving primary sealing of the front window glass; when the front window glass is raised into place, the position sensor outputs an electrical signal to the controller, and the controller causes the inner sealing strip and the outer sealing strip to be completely moved out to a second position, thereby achieving secondary sealing of the front window glass.

[0014] In this solution, when the front window needs to be raised to prevent wind, the "up" control position is pressed, and only the inner sealing strip is synchronously moved out to the first position close to the front window. In other words, the outer sealing strip remains stationary. Only when it rains and the front window is fully raised, the controller will completely move the inner and outer sealing strips out to the second position to achieve secondary sealing of the front window. In this way, the wear of the rear sealing strip is minimized while ensuring rain protection.

[0015] Preferably, the inner sealing strip and the outer sealing strip include a sliding strip movably arranged in the B-pillar and a sealing strip for sealing, and the front end of the sliding strip is embedded in the sealing strip.

[0016] The sliding strip facilitates the movement of the inner sealing strip and the outer sealing strip, and can be used as an inlay so that the front end of the sliding strip is embedded in the sealing strip to form an elastic framework of the sealing strip.

[0017] Preferably, the sealing strip also includes a front sealing strip arranged on the rear side of the A-pillar and an upper sealing strip arranged on the lower side of the roof, and the front sealing strip and the upper sealing strip respectively include an inner sealing strip and an outer sealing strip. When the "up" control position is pressed, the front window glass rises, and the controller causes the inner sealing strip of the front sealing strip to be synchronously moved out to a first position close to the front window glass, thereby achieving primary sealing of the front window glass; when the front window glass is raised into place, the position sensor outputs an electrical signal to the controller, and the controller causes the inner sealing strip and the outer sealing strip of the front sealing strip and the upper sealing strip to be completely moved out to a second position, thereby achieving secondary sealing of the front window glass.

[0018] In this solution, the sealing strip also includes a front sealing strip arranged at the rear side of the A-pillar and an upper sealing strip arranged at the lower side of the roof, and the front sealing strip and the upper sealing strip also include an inner sealing strip and an outer sealing strip, thereby achieving complete sealing of the front window glass.

[0019] Preferably, the B-pillar includes an internal interior trim, a supporting sheet metal part located in the middle, and a plastic exterior trim part covering the outside of the supporting sheet metal part. The upper end of the supporting sheet metal part is rotatably connected to the roof, the lower end of the supporting sheet metal part is clamped to the body sheet metal part, and the exterior trim part is clamped to the interior trim part.

[0020] During assembly, the upper end of the B-pillar supporting sheet metal can be rotated and connected to the roof first, then the supporting sheet metal can be rotated downward and pressed, and then the lower end of the supporting sheet metal can be snapped into the body sheet metal, and then the exterior trim can be pressed to snap into the interior trim, thereby achieving quick assembly.

[0021] Preferably, retractable rotating pins are respectively provided on the left and right sides of the upper end of the supporting sheet metal component, and the rotating pins are rotatably inserted into the sheet metal component inside the roof.

[0022] The retractable pivot pin facilitates the support of the upper end of the sheet metal component to form a pivot connection with the sheet metal component inside the roof.

[0023] Therefore, the present invention has the following beneficial effects: it can effectively simplify the structure and assembly procedures, reduce manufacturing costs, improve the aesthetics of the B-pillar, and effectively improve the sealing effect of the front window.

[0029] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. DETAILED DESCRIPTION

[0030] like Figure 1 , Figure 2As shown, a B-pillar of an automobile is provided, wherein the B-pillar 1 is fixedly connected between a roof 2 and a middle part of a vehicle body 3, a rear door 4 of the automobile is rotatably connected to the rear side of the B-pillar, the B-pillar comprises a sealing strip 5 for sealing a front window glass 6, the sealing strip comprises a rear sealing strip 51 arranged on the front side of the B-pillar, the rear sealing strip is associated with a power mechanism (not shown in the figure) comprising a controller, so that the rear sealing strip is movably arranged on the front side of the B-pillar, the moving direction of the rear sealing strip forms an angle of 5°-10° with the front window glass raised to the rear sealing strip, the power mechanism comprises a linkage switch (not shown in the figure) arranged on the inner side of the front door, and a position sensor for detecting the position of the front window glass, the linkage switch comprises a "raise" and "lower" control position which can be activated in an inching manner. When it is raining and the front window needs to be raised, the person in the car can press the "up" control position of the linkage switch. At this time, the front window rises, and the controller causes the rear sealing strip located in the B-pillar to move out synchronously to the first position close to the front window, thereby achieving the primary sealing of the front window; when the front window is raised in place, the position sensor outputs an electrical signal to the controller, and the controller causes the rear sealing strip to move completely out to the second position, thereby achieving the secondary sealing of the front window; when the rain stops and the front window needs to be opened, the person in the car can press the "down" control position of the linkage switch. At this time, the front window drops, and at the same time, the controller causes the rear sealing strip to move backward synchronously to the first position; when the front window is completely dropped into the front door, the position sensor outputs an electrical signal to the controller, and the controller causes the rear sealing strip to move backward into the B-pillar.

[0031] That is to say, the so-called first-level sealing is the primary sealing of the front window glass, which is mainly used to prevent wind; only the second-level sealing is the deep sealing of the front window glass, which is mainly used to prevent rain.

[0032] Since the rear sealing strip that seals the front window glass is arranged on the front side of the B-pillar and is separated from the front window glass arranged in the front door, thus forming a frameless (front) window, the B-pillar does not need to include a front B-pillar as part of the front door frame, which can effectively simplify the B-pillar structure and assembly procedures and reduce manufacturing costs, and is conducive to improving the aesthetics of the B-pillar.

[0033] In addition, the moving direction of the rear sealing strip forms an angle of 5°-10° with the front window glass raised to the rear sealing strip. Therefore, when the rear sealing strip is located in the B-pillar, even if the front window glass rises, the rear sealing strip will not interfere with the front window glass. When the "up" control position of the linkage switch is pressed and the front window glass is raised, the rear sealing strip located in the B-pillar is synchronously moved out to the first position just against the front window glass. That is to say, before moving to the first position, the rear sealing strip is in a disengaged state from the front window glass to facilitate the rising of the front window glass; when the front window glass rises to the position, the position sensor outputs an electrical signal to the controller, and the controller completely moves out to the second position, thereby realizing the secondary sealing of the front window glass. That is to say, the rear sealing strip will only be tightly against the front window glass between the first position and the second position. It is understandable that we can reasonably set the first position and the second position according to needs, and minimize the friction between the rear sealing strip and the front window glass to improve the sealing effect under the premise of convenient lifting. In addition, when the front window glass needs to be lowered and the "down" control position of the linkage switch is pressed, the rear sealing strip can be retracted first, and then the front window glass can be lowered to effectively avoid friction between the front window glass and the rear sealing strip.

[0034] As a preferred embodiment, the rear sealing strip includes an inner sealing strip 511 and an outer sealing strip 512. When the rear sealing strip moves outward, the inner sealing strip is located on the inner side of the front window glass, and the moving direction of the inner sealing strip is inclined from the inside to the outside; the outer sealing strip is located on the outer side of the front window glass, and the moving direction of the outer sealing strip is inclined from the outside to the inside, thereby clamping the front window glass between the inner sealing strip and the outer sealing strip.

[0035] It is understandable that when the rear sealing strip is located inside the B-pillar, the distance between the inner sealing strip and the outer sealing strip may be greater than the thickness of the front window glass, thereby ensuring the smooth rising of the front window glass.

[0036] Furthermore, when the linkage switch is pressed to the "up" control position, the front window glass rises, and at the same time, the controller causes the inner sealing strip located in the B-pillar to be synchronously moved out to the first position close to the front window glass, thereby achieving the primary sealing of the front window glass. In other words, the outer sealing strip is still located inside the front side of the B-pillar at this time; when the front window glass rises to the right position, the position sensor outputs an electrical signal to the controller, and the controller causes the inner and outer sealing strips to be completely moved out to the second position, thereby achieving the secondary sealing of the front window glass.

[0037] That is to say, only when it rains and the front window glass is fully raised, the controller will completely move the inner and outer sealing strips to the second position to achieve secondary sealing of the front window glass, thereby minimizing the wear of the rear sealing strip while ensuring rain protection.

[0038] To facilitate the movement of the inner and outer sealing strips, Figure 3 As shown, the inner sealing strip and the outer sealing strip both include a sliding strip 514 movably arranged in the B-pillar and a sealing strip 513 for sealing. The sliding strip is used as an inlay when the sealing strip is molded, and its front end is embedded in the sealing strip. In other words, the sliding strip becomes the elastic skeleton of the sealing strip, which not only ensures the sealing effect of the inner sealing strip and the outer sealing strip on the front window glass, but also facilitates the forward and backward movement of the inner sealing strip and the outer sealing strip.

[0039] As another preferred solution, the sealing strip also includes a front sealing strip 52 arranged on the rear side of the A-pillar 11 and an upper sealing strip 53 arranged on the lower side of the roof, so as to achieve a complete sealing effect on the front window glass. In addition, similar to the rear sealing strip, the front sealing strip and the upper sealing strip respectively include an inner sealing strip and an outer sealing strip. In this way, when the "up" control position of the linkage switch is pressed, the front window glass rises, and the controller causes the inner sealing strip of the rear sealing strip to be synchronously moved out to the first position close to the front window glass. At the same time, the inner sealing strip of the front sealing strip is synchronously moved out to the first position close to the front window glass, thereby achieving the primary sealing of the front window glass; when the front window glass rises to the position, the position sensor outputs an electrical signal to the controller, and the controller causes the inner sealing strip and the outer sealing strip of the front sealing strip, the upper sealing strip, and the rear sealing strip to be completely moved out to the second position, thereby achieving the secondary sealing of the front window glass.

[0040] To facilitate the assembly and connection of the B-pillar, Figure 4 As shown, the B-pillar includes an internal interior trim 12, a supporting sheet metal 13 located in the middle, and a plastic exterior trim 14 covering the outside of the supporting sheet metal. The upper end of the supporting sheet metal is rotatably connected to the roof, the lower end of the supporting sheet metal is clamped to the body sheet metal, and the exterior trim is clamped to the interior trim.

[0041] During assembly, the upper end of the B-pillar supporting sheet metal can be rotated and connected to the roof first, then the supporting sheet metal can be rotated downward and pressed, and then the lower end of the supporting sheet metal can be snapped into the body sheet metal, and then the exterior trim can be pressed to snap into the interior trim, thereby achieving quick assembly.

[0042] Furthermore, we can respectively set retractable rotating pins 131 on the left and right sides of the upper end of the supporting sheet metal, and the rotating pins can be rotatably plugged into the sheet metal inside the roof. The retractable rotating pins facilitate the rotational connection and disassembly between the upper end of the supporting sheet metal and the sheet metal inside the roof.
