Description

Technical Field

[0001] The present application relates to the field of automobile technical accessory installation, and in particular to a pillar trim panel and a vehicle door. Background Art

[0002] With the upgrading of automobile technology and the popularization of automobiles, consumers are more picky about the appearance and performance of automobiles. As an important component of the automobile, the side pillar trim of the automobile door makes a great contribution to the appearance, MVH and dustproof performance of the automobile.

[0003] In the related art, the inner and outer panels of the column trim are fixed to the sheet metal by a bonding process through self-tapping screws and plastic nuts; however, there are the following problems:

[0004] (1) The bonding strength of the inner and outer panels of the column trim is unstable, and due to the existence of manufacturing dimensional errors of the inner and outer panels, the matching effect of the inner and outer panels is poor, the dustproof performance is poor, and the appearance is affected.

[0005] (2) Car doors with pillar trim panels are prone to abnormal noise during use. After investigation, it was found that the abnormal noise mainly comes from three aspects. First, the soft rubber of the pillar trim panel is relatively stiff, which is easy to produce friction abnormal noise during road tests; second, the glass is not firmly fixed, and abnormal noise occurs during the door closing process due to the vibration of the door closing. Third, the installation method of the pillar trim panel door usually uses self-tapping screws and plastic nuts, which have a small load torque, are not firmly fixed, and have loose defects. Abnormal noise is easy to occur during the door closing process and the glass lifting process. Summary of the invention

[0006] The embodiments of the present application provide a pillar trim and a vehicle door to solve the problem in the related art that a vehicle door equipped with a pillar trim is prone to abnormal noise during use.

[0007] In a first aspect, a column trim is provided, comprising:

[0008] The pillar trim body comprises an inner plate and an outer plate; an extended guide rail is provided at the bottom of the inner plate, and a first side edge of the extended guide rail clamping the door glass is colinear and parallel to a second side edge of the inner plate clamping the door glass;

[0009] The rubber strip is connected to a side edge of the inner plate away from the second side edge, and the transition angle of the root where the rubber strip is connected to the inner plate is an obtuse angle.

[0010] In the above structure, the extended guide rail increases the supporting length of the door glass, so that the door glass is firmly fixed and there is no vibration or abnormal noise when the door is closed; in addition, because the rubber strip is connected to the side edge of the inner panel away from the second side edge; the transition angle of the root of the connection between the rubber strip and the inner panel is an obtuse angle, thereby weakening the overall stiffness of the rubber strip to prevent abnormal noise caused by friction between the soft rubber and the sheet metal contact surface during the road test, thereby solving the problem of abnormal noise that is easy to occur during use.

[0011] In some embodiments, the inner panel, outer panel and rubber strip are integrally formed by a three-color injection molding process. The three-color injection molding process and the integral molding mold can be used to produce the pillar trim in one go, so that the inner panel and the outer panel have the same size error, the appearance matching effect is good, and the connection strength is higher than that of the bonding form, and cracking will not occur, ensuring the dustproof sealing effect. When the rubber strip is injected, the cooling shrinkage tolerance of the inner panel is compensated, the injection molding flash defect is prevented, and the appearance quality is improved.

[0012] In some embodiments, the thickness of the root where the rubber strip is connected to the inner panel is 0.9-1.1 mm.

[0013] In some embodiments, the thickness of the root where the rubber strip is connected to the inner panel is 1 mm.

[0014] In some embodiments, the transition angle is 120°-180°; and the length of the extended guide rail is 100-150 mm.

[0015] In a second aspect, a vehicle door is provided, comprising:

[0016] A door sheet metal structure with a pillar trim installed on the door sheet metal structure.

[0017] In some embodiments, the door sheet metal structure is provided with an L-shaped connection groove;

[0019] In some embodiments, the positioning structure includes a sheet metal bonding plate, a positioning column and a push rod, one end of the push rod is connected to the inner plate, and the other end is connected to the sheet metal bonding plate;

[0020] One end of the positioning column is vertically fixedly connected to a side of the sheet metal bonding plate away from the top rod, and the other end is penetrated by the L-shaped connecting groove. A positioning protrusion is provided on the outer peripheral side surface of one end of the positioning column in the L-shaped connecting groove; a limiting groove is formed between the positioning protrusion and the sheet metal bonding plate. The extended guide rail of the pillar trim body is first inserted into the door in the Z direction, and the positioning column of its positioning structure first contacts the L-shaped connection groove on the door sheet metal structure, slides to the initial position in the Z direction, and slides to the bottom of the L-shaped connection groove; then slides in the X direction, and after sliding to the top of the bottom of the L-shaped connection groove in the X direction, it is limited in the Z direction and in the X direction; at the same time, the Y-direction limitation principle is that the limiting groove formed between the positioning protrusion and the sheet metal bonding plate is clamped with the side of the L-shaped connection groove of the door sheet metal structure, so that the position of the positioning column in the Y direction is limited and will not move, which plays a role in pre-installation and positioning; thus coordinating the positioning in the three directions of X, Y, and Z; in the above positioning and installation process, there is no need to measure and position, only need to insert the extended guide rail into the door in the Z direction first, and then clamp the positioning column with the top of the L-shaped connection groove to install and position, which ensures the installation accuracy and speeds up the installation time. The above three directions of X, Y, and Z refer to the height direction of the vehicle, the width direction of the vehicle, and the length direction of the vehicle, respectively.

[0021] In some embodiments, the width of the vertical portion of the L-shaped connecting groove is equal to the diameter of the positioning column; and the width of the horizontal portion of the L-shaped connecting groove is twice the diameter of the positioning column.

[0022] In some embodiments, a screw hole is provided on the inner plate and located on the second side, and a self-chip removal bolt is provided in the screw hole;

[0023] The door sheet metal structure is provided with a rubber strip contact surface and a back surface opposite to the rubber strip contact surface, and a connecting nut is welded on the back surface; the self-chip removal bolt is connected to the connecting nut;

[0024] A reinforced connection groove is provided on the side of the door sheet metal structure with the rubber strip contact surface; and a reinforced connection part connected to the reinforced connection groove is provided on the inner plate. The connection nut and the self-removal bolt are used in combination. The self-removal bolt has a high connection strength and is suitable for installing heavy items or items that need to withstand heavy pressure; the connection of the bolt is stable and will not loosen by itself. In addition, the reinforced connection groove and the reinforced connection part are connected by bolts, which further ensures the stability of the connection between the pillar trim body and the door sheet metal structure, and the installation is carried out from the inside of the vehicle, so that the outside and inside of the door sheet metal structure are tightened.

[0025] The beneficial effects of the technical solution provided by this application include:

[0026] The embodiment of the present application provides a pillar trim panel and a vehicle door. Since the pillar trim panel body has an inner panel and an outer panel, an extended guide rail is provided at the bottom of the inner panel, and the first side edge of the extended guide rail clamping the vehicle door glass is colinear and parallel with the second side edge of the inner panel clamping the vehicle door glass. A rubber strip is connected to a side edge of the inner panel away from the second side edge, and the transition angle of the root of the connection between the rubber strip and the inner panel is an obtuse angle. In the above structure, the extended guide rail increases the supporting length of the vehicle door glass, so that the vehicle door glass is firmly fixed and there is no vibration or abnormal noise when closing the door. In addition, since the transition angle of the connection between the rubber strip and a side edge of the inner panel away from the second side edge is an obtuse angle, the overall stiffness of the rubber strip is weakened to prevent abnormal noise caused by friction during road tests, thereby solving the problem of abnormal noise that is easy to occur during use.

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0036] The inner and outer panels of the column trim are fixed to the sheet metal by a bonding process through self-tapping screws and plastic nuts; it can refer to the Chinese patent CN217575075U, which discloses that the materials of the outer panel of the trim and the limiting component are different. Sometimes a two-color injection molding process is required to manufacture the column trim, which leads to expensive mold costs for the column trim. In this embodiment, the outer panel of the trim and the limiting component are manufactured separately by a single-color injection molding process. In this way, the outer panel of the trim and the limiting component are manufactured separately, which can reduce mold costs and reduce the difficulty of demolding the column trim. The separately manufactured outer panel of the trim and the limiting component can be fixedly connected by bonding, bolting, etc., to form a column trim.

[0037] But there are the following problems:

[0038] (1) The bonding strength of the inner and outer panels of the column trim is unstable, and due to the existence of manufacturing dimensional errors of the inner and outer panels, the matching effect of the inner and outer panels is poor, the dustproof performance is poor, and the appearance is affected.

[0039] (2) Car doors with pillar trim panels are prone to abnormal noise during use. After investigation, it was found that the abnormal noise mainly comes from three aspects. First, the soft rubber of the pillar trim panel is relatively stiff, and the contact surface between the soft rubber and the sheet metal is prone to friction and abnormal noise during road tests. Second, the glass is not firmly fixed, and abnormal noise occurs during the door closing process due to the vibration of the door closing. Third, the installation method of the pillar trim panel door usually uses self-tapping screws and plastic nuts, which have a small load torque, are not firmly fixed, and have loose defects. Abnormal noise is prone to occur during the door closing process and the glass lifting process.

[0040] (3) The positioning of the column trim is not precise enough, making assembly inconvenient.

[0041] Since the car has further requirements for appearance, MVH, and dustproof performance, the pillar trim and door are proposed to solve the above problems. The following are explained one by one:

[0042] First, for the column trim only, refer to Figure 1-Figure 4 , providing a column trim, comprising:

[0043] The pillar trim body 1 includes an inner plate 100 and an outer plate 101; an extended guide rail 2 is provided at the bottom of the inner plate 100, and the first side edge of the extended guide rail 2 clamping the door glass is colinear and parallel to the second side edge 102 of the inner plate 100 clamping the door glass;

[0044] The rubber strip 3 is connected to a side of the inner panel 100 away from the second side 102, and the transition angle of the root where the rubber strip 3 is connected to the inner panel 100 is an obtuse angle. The rubber strip 3 is TPE soft rubber.

[0045] In the above structure, the lengthened guide rail 2 increases the supporting length of the door glass, so that the door glass is firmly fixed and there is no vibration or abnormal noise when the door is closed; in addition, since the rubber strip 3 is connected to the side edge of the inner panel 100 away from the second side edge 102; the transition angle of the root of the connection between the rubber strip 3 and the inner panel 100 is an obtuse angle, thereby weakening the overall stiffness of the rubber strip 3 to prevent abnormal noise caused by friction between the soft rubber and the sheet metal contact surface during the road test, thereby solving the problem of abnormal noise that is easy to occur during use.

[0046] In some preferred embodiments, in order to solve the problem that the bonding strength of the inner and outer panels of the column trim is unstable, and the inner and outer panels have poor matching effects and poor dustproof performance due to the manufacturing size errors of the inner and outer panels, which affects the appearance, the following settings are provided:

[0047] The inner plate 100, the outer plate 101 and the rubber strip 3 are integrally formed by a three-color injection molding process. The principle of three-color injection molding is that on an injection molding machine, by setting multiple injection devices and multiple color material supply systems in the mold, plastic materials of different colors are injected into the mold at the same time, so that the molded plastic products have multiple colors. The specific principle is as follows:

[0048] Through multiple injection devices equipped with different colors of molten plastic barrels and nozzles, each injection device can independently control its injection speed and pressure to ensure that each colorant can enter the mold according to the set ratio. Each injection device has a corresponding colorant supply system, which is used to heat and melt plastic particles of different colors and transport them to the injection device through the colorant supplier. There are multiple injection cavities in the mold, each of which is used to inject molten plastic of one color. The mold will arrange the injection cavities of different colors reasonably according to the requirements of the design documents to ensure that the injection molded products can form the required color effects. When the injection molding machine is working, first open the injection device of the corresponding color and inject the corresponding molten plastic into the injection cavity of the mold. After the injection plastic cools and solidifies, open the mold and take out the molded three-color injection molded product.

[0049] The pillar trim can be manufactured in one go through the three-color injection molding process and the one-piece molding mold, so that the inner panel 100 and the outer panel 101 have the same size error, the appearance matching effect is good, and the connection strength is higher than that of the bonding form, and there will be no cracking phenomenon, ensuring the dustproof sealing effect. When the rubber strip 3 is injected, the cooling shrinkage tolerance of the inner panel 100 is compensated, the injection flash defect is prevented, and the appearance quality is improved.

[0050] In some preferred embodiments, in order to further reduce the rigidity of the rubber strip 3, the following settings are also provided: the thickness of the root where the rubber strip 3 is connected to the inner plate 100 is 0.9-1.1 mm; the most preferred thickness of the root where the rubber strip 3 is connected to the inner plate 100 is 1 mm. The transition angle is 120°-180°. Figure 3 As shown, the root of the rubber strip 3 is finally weakened, the rigidity of the rubber strip 3 is reduced, and abnormal noise caused by friction during road tests is prevented.

[0051] The length of the extended guide rail 2 is 100-150mm, which increases the supporting length of the door glass, so that the glass is firmly fixed and there is no vibration or abnormal sound when closing the door.

[0052] The above only solves the problem of unstable bonding strength of the inner and outer panels of the pillar trim, as well as some abnormal noise problems. In order to optimize the solution to all the above problems, this application has made some adjustments to the door sheet metal structure 5 to match the pillar trim.

[0053] Second, reference Figure 1-Figure 6 , a vehicle door is proposed, comprising:

[0054] The door sheet metal structure 5 has a pillar trim installed on it.

[0055] An L-shaped connecting groove 6 is provided on the door sheet metal structure 5;

[0056] A positioning structure 4 connected to the L-shaped connecting groove 6 is provided on the top of the inner plate 100 of the pillar trim body 1 .

[0057] The positioning structure 4 includes a sheet metal bonding plate 400, a positioning column 401 and a push rod 403, one end of the push rod 403 is connected to the inner panel 100, and the other end is connected to the sheet metal bonding plate 400; the sheet metal bonding plate 400 can ensure that it is always in contact with the door sheet metal structure 5 having the L-shaped connection groove 6 during installation, and the inner panel 100 will not deviate in the vehicle width direction. That is, the sheet metal bonding plate 400 will not pass through the L-shaped connection groove 6.

[0058] One end of the positioning column 401 is vertically fixedly connected to a side of the sheet metal bonding plate 400 away from the top rod 403, and the other end is penetrated by an L-shaped connecting groove 6. A positioning protrusion 402 is provided on the outer peripheral side of one end of the positioning column 401 provided with the L-shaped connecting groove 6; a limiting groove is formed between the positioning protrusion 402 and the sheet metal bonding plate 400. Figure 3 , Figure 5 , Figure 6 The structure shown.

[0059] refer to Figure 4 Through the above structural setting, the extended guide rail 2 is used for positioning and installation. The specific steps of installation are as follows: Figure 5 As shown:

[0060] The extended guide rail 2 of the pillar trim body 1 is first inserted into the vehicle door in the Z direction, and the positioning column 401 of its positioning structure 4 first contacts the L-shaped connecting groove 6 on the vehicle door sheet metal structure 5, slides to the initial position in the Z direction, and slides to the bottom of the L-shaped connecting groove 6; then slides in the X direction, and after sliding to the top of the bottom of the L-shaped connecting groove 6 in the X direction, it is limited in the Z direction and in the X direction; at the same time, the Y-direction limitation principle is that the limiting groove formed between the positioning protrusion 402 and the sheet metal bonding plate 400 is clamped with the side of the L-shaped connecting groove 6 of the vehicle door sheet metal structure 5, so that the position of the positioning column 401 in the Y direction is limited and will not move, which plays a role in pre-installation and positioning; thereby coordinating the positioning in the three directions of X, Y, and Z; in the above positioning and installation process, there is no need to measure and position, you only need to first insert the extended guide rail 2 into the vehicle door in the Z direction, and then clamp the positioning column 401 with the top of the L-shaped connecting groove 6 to install and position it, which ensures installation accuracy while also speeding up installation time. The above three directions X, Y, and Z refer to the height direction of the vehicle, the width direction of the vehicle, and the length direction of the vehicle, respectively.

[0061] Furthermore, in order to allow the positioning column 401 to have sliding space in the Z direction and the X direction in the L-shaped connecting groove 6, the following configuration is provided:

[0062] The width of the vertical portion of the L-shaped connecting groove 6 is equal to the diameter of the positioning column 401 ; the width of the horizontal portion of the L-shaped connecting groove 6 is twice the diameter of the positioning column 401 .

[0063] In some preferred embodiments, in order to solve the problem that the installation method of the pillar trim door usually uses self-tapping screws and plastic nuts, the bearing torque is small, the fixation is not reliable, there is a loose defect, and abnormal noise is easy to occur during the door closing process and the glass lifting process, the following settings are provided:

[0064] A screw hole is provided on the inner plate 100 and located on the second side 102, and a self-chip removal bolt 7 is provided in the screw hole;

[0065] The door sheet metal structure 5 is provided with a rubber strip contact surface 501 and a back surface opposite to the rubber strip contact surface 501, and a connecting nut 500 is welded on the back surface; the self-chip removal bolt 7 is connected to the connecting nut 500;

[0066] A reinforcing connection groove 502 is provided on the side of the door sheet metal structure 5 having the rubber strip contact surface 501 ; a reinforcing connection portion 103 connected to the reinforcing connection groove 502 is provided on the inner panel 100 .

[0067] The reason is that self-tapping screws do not need to be pre-drilled when used. Self-tapping screws need to be pressed in with appropriate tools. If the tools are used improperly, the strength of the finished product will be insufficient. When self-tapping screws are used in conjunction with plastic nuts, the bearing torque is small, the fixation is not reliable, and there is a defect of loosening when pressed.

[0068] The connection nut 500 and the self-chip removal bolt 7 are used together. The self-chip removal bolt 7 has a high connection strength and is suitable for installing heavy objects or objects that need to withstand heavy pressure. The bolt connection is stable and will not loosen by itself. In addition, the strengthening connection groove 502 and the strengthening connection part 103 are connected by bolts, which further ensures the stability of the connection between the pillar trim body 1 and the door sheet metal structure 5. The installation is carried out from the inside of the vehicle, and the outside and inside of the door sheet metal structure 5 are tightened.

[0069] Through the above description, improvements have been made to the door sheet metal structure 5 and the pillar trim to solve the problem of abnormal noise and strengthen the positioning connection strength. The pillar trim has high dimensional accuracy, and it is not easy to produce burrs on the appearance, which improves the overall appearance; the pillar trim bolts are firmly fixed, and the pillar trim is not easy to loosen when pressed, and there will be no abnormal noise problem; the long guide rail feature design of the pillar trim increases the support length of the door glass, the glass is firmly fixed, and there is no vibration or abnormal noise when the door is closed. The pillar trim has a structural feature that positions three directions, and the positioning method is relatively accurate, which is beneficial to the production and manufacturing process.

[0070] In a third aspect, the present application further proposes a vehicle, the front door and the rear door of the vehicle can both be applied with the above-described:

[0072] Through the above structural setting, the extended guide rail 2 is used for positioning and installation. The specific steps of installation are as follows:

[0073] The extended guide rail 2 of the pillar trim body 1 is first inserted into the door in the Z direction, and the positioning column 401 of the positioning structure 4 first contacts the L-shaped connecting groove 6 on the door sheet metal structure 5, and slides to the initial position in the Z direction and slides to the bottom of the L-shaped connecting groove 6; then slides in the X direction, and after sliding to the top of the bottom of the L-shaped connecting groove 6 in the X direction, it is limited in the Z direction and in the X direction; at the same time Figure 2 and Figure 5 As shown, the Y-direction restriction principle is expressed. The limiting groove formed between the positioning protrusion 402 and the sheet metal bonding plate 400 is clamped with the side of the L-shaped connecting groove 6 of the door sheet metal structure 5, so that the position of the positioning column 401 in the Y direction is limited and will not move, which plays a role in pre-installation and positioning; thereby coordinating the positioning in the three directions of X, Y, and Z; in the above positioning and installation process, there is no need to measure and position, only need to first insert the Z direction into the door through the extended guide rail 2, and then clamp the positioning column 401 with the top of the L-shaped connecting groove 6 to install and position, which ensures the installation accuracy and speeds up the installation time.
