Description

Technical Field

[0001] The invention relates to the field of vehicle door parts installation, in particular to a fixing structure of a front door inner triangular cover. Background Art

[0002] Currently, a triangular area is formed on the front window of a vehicle, which is generally used to install the exterior rearview mirror and the front inner triangle cover. The exterior rearview mirror is fixed to the outside side of the triangular area, while the front inner triangle cover is fixed to the inside side of the triangular area.

[0003] In the prior art, to ensure the installation of the exterior mirror, the upper space of the triangular area is used to secure the exterior mirror. This prevents the exterior mirror from being unstable due to the mirror being fixed too low. In severe cases, this can cause vibration and noise from the exterior mirror during driving. Because the triangular area is larger at the top and smaller at the bottom, in order to secure the front inner triangle cover to the triangular area, the fixing point of the front inner triangle cover must be moved downward.

[0004] However, lowering the fixing point of the front inner triangle cover requires more space in the triangle area, which often does not conform to the overall shape of the vehicle. At the same time, if the fixing point of the front inner triangle cover is too low, it may cause the front inner triangle cover to be fixed loosely, which may easily cause a gap in the top of the front door inner triangle cover. If the two are arranged at the same height, the front door inner triangle cover will be fixed to the guide rail position, which may affect the installation of the glass run channel at the guide rail position, and thus affect the vehicle's NVH (Noise, Vibration, Harshness) performance. Summary of the Invention

[0005] An embodiment of the present invention provides a fixing structure for a front door inner triangular cover to solve the problem in the related art that the front door inner triangular cover and the exterior rearview mirror are installed together in a triangular area, resulting in a decrease in the installation performance of the front inner triangular cover.

[0010] In some embodiments, the clamping claw is provided with reinforcing ribs.

[0011] In some embodiments, the reinforcing rib is located on a side of the clamping claw away from the clamping space.

[0012] In some embodiments, the claws of the clamping member are evenly spaced apart along the circumferential direction.

[0013] In some embodiments, the outer hoop of the clamping member is provided with a hoop body, and the hoop body is simultaneously provided outside all the claws. Each claw is provided with a limiting groove on the side away from the anti-slip protrusion, and the hoop body is provided at the limiting groove.

[0014] In some embodiments, the exterior rearview mirror includes a shell, a mirror body is mounted on the shell, the fixing bolt is fixed to the shell, the shell is provided with a jet channel extending to the fixing bolt, and the jet channel faces the working surface of the mirror body; the fixing bolt is provided with an air hole passing through the fixing bolt, and the air hole is connected to the jet channel; the end of the fixing bolt away from the shell extends out of the connector and is connected to the jet pipe, and the air hole is connected to the high-pressure air pump through the jet pipe.

[0015] In some embodiments, a first inclined surface is provided at one end of the anti-slip protrusion away from the triangular cover body; along the direction in which the anti-slip protrusion approaches the disk body, the first inclined surface gradually deviates toward the axis of the clamping space.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0040] An embodiment of the present invention provides a fixing structure for a front door inner triangular cover, which can solve the problem in the related art that the front door inner triangular cover and the exterior rearview mirror are installed together in a triangular area, resulting in a decrease in the installation performance of the front inner triangular cover.

[0041] See also Figure 5 As shown, it is a fixing structure for fixing the exterior rearview mirror and the front door inner triangular cover at the triangular inner panel in the prior art, wherein the exterior rearview mirror is fixed to the outer side of the triangular inner panel via a first exterior rearview mirror fixing position B with a threaded connection, and the front door inner triangular cover is fixed to the first front door inner triangular cover fixing position C via bolts or clips. It can be seen that the space of the triangular inner panel is very limited, the first exterior rearview mirror fixing position B is higher than the first front door inner triangular cover fixing position C, and the distance between the two fixing positions is very narrow. Interference or difficulty in installation is likely to occur during the installation process. At the same time, since the first front door inner triangular cover fixing position C is relatively low, the top of the front door inner triangular cover cannot be firmly fixed, which may cause the front door inner triangular cover to be unstable in installation and have a poor gap with the vehicle window frame, making it difficult to meet the installation requirements of the front door inner triangular cover.

[0042] See also Figure 6 and Figure 7 As shown, another fixing structure for the front door inner triangular cover in the prior art, wherein the second exterior rearview mirror fixing position D for fixing the exterior rearview mirror is also located at the top of the triangular inner panel, and the second front door inner triangular cover fixing position E for fixing the front door inner triangular cover is set at the guide rail portion of the triangular inner panel edge. It can be seen that the heights of the two parts fixing points are roughly the same. However, since the front door inner triangular cover fixing position is set at the guide rail portion of the triangular inner panel, the installation position of the glass guide groove on the guide rail will deviate from the optimal position, which may cause the glass guide groove gap to be too large, thereby affecting the NVH performance of the vehicle. In summary, the existing fixing methods for the front door inner triangular cover cannot meet the vehicle's installation requirements for parts at the triangular inner panel, and it is necessary to propose a new fixing method for the front door inner triangular cover.

[0043] See also Figures 1 to 4As shown, a fixing structure of a front door inner triangular cover provided by an embodiment of the present invention comprises: a triangular inner panel 1; an exterior rearview mirror 2, the exterior rearview mirror 2 being fixed to the outer side of the triangular inner panel 1 by a fixing bolt 3, the fixing bolt 3 being passed from the outer side of the triangular inner panel 1 to the inner side of the triangular inner panel 1; a connector 5, the connector 5 being located on the inner side of the triangular inner panel 1 and being threadedly connected to the fixing bolt 3; a front door inner triangular cover 4, the front door inner triangular cover 4 being provided with a clamping member 41, the clamping member 41 being clamped to the connector 5. In other words, the exterior rearview mirror 2 is fixed to the outer side of the vehicle by the fixing bolt 3, and the interior front door triangular cover 4 located on the inner side of the vehicle is fixed to the inner side of the vehicle by the fixing bolt 3 passing through the triangular inner panel 1 to the inner side of the vehicle and connected to the connector 5. This not only satisfies the installation of two parts inside and outside the vehicle, but also realizes installation in a narrow space by sharing a mounting position between the exterior rearview mirror 2 and the interior front door triangular cover 4. The exterior rearview mirror 2 and the front door inner triangular cover 4 can both be installed on the top area of the triangular inner panel 1, while ensuring the installation reliability of both, avoiding the front door inner triangular cover 4 being installed on the bottom of the triangular inner panel 1, and reducing the problem of the front door inner triangular cover 4 being installed unreliably. Moreover, since the installation position is shared, the number of installation components can be reduced, the related installation structures of the parts can be reduced, and the risk of inconvenient operation or interference during the installation process can be reduced. Among them, since the front door inner triangular cover 4 does not need to be fixed on the guide rail of the triangular inner panel 1, the guide groove can be firmly installed on the guide rail position, which is beneficial to improving the NVH performance of the vehicle. In this embodiment, in order to fix the exterior rearview mirror 2 with a larger mass, the exterior rearview mirror 2 is fixed to the triangular inner panel 1 with bolts, which can firmly fix the exterior rearview mirror 2 with a larger mass. Fixing the front door inner triangular cover 4 by snapping is more convenient than threaded connection. No external tools are required when connecting the front door inner triangular cover 4 to the connector 5, which reduces the difficulty of installing the front door inner triangular cover 4 in a small space. In this embodiment, the snap-in piece 41 of the triangular cover 4 inside the front door is snap-connected with the disc body 51 of the connecting body 5. In other embodiments, a snap-in groove for the snap-in piece 41 or other non-circular protrusions for the snap-in piece 41 can be provided on the connecting body 5 to prevent the snap-in piece 41 from rotating relative to the connecting body 5 during the connection process.

[0044] See also Figures 1 to 3As shown, preferably, the connector 5 includes a disk 51, which is parallel to the triangular lining 1; the clamping member 41 includes a plurality of claws 411, which surround a clamping space 42. The clamping member 41 is clamped to the side edge of the disk 51 to accommodate the disk 51 in the clamping space 42, and the clamping member 41 can rotate about the disk 51. In other words, the disk 51, which is parallel to the triangular lining 1, is clamped by the claws 411 of the clamping member 41. The plurality of claws 411 are clamped on the side edge of the disk 51, clamping the disk 51 in the clamping space 42 formed by the claws 411. Due to the clamping of the disk 51, the circular outer edge of the disk 51 can achieve rotation of the front door inner triangular cover 4 relative to the triangular lining 1 during the clamping process. This provides adjustment space during the installation process, allowing for accurate fixation of other positions of the front door inner triangular cover 4, and facilitating multi-point fixation of the front door inner triangular cover 4. Because the clamping member 41 is engaged with the side edge of the disc 51 via the claws 411, the volume of the connector 5 can be reduced compared to slotting the connector 5. In this embodiment, the disc 51 is a disc with a thickness of 0.7 mm to 1.2 mm and a diameter of approximately 9 mm. This thin thickness and large diameter allows for quick engagement of the claws 411 and prevents interference between the claws 411 and the fixing bolt 3. In other embodiments, the disc 51 can be of different sizes depending on the specific installation space.

[0045] See also Figure 4 As shown, preferably, the connector 5 is provided with a threaded hole 52 that passes through the connector 5, and the threaded hole 52 is threadedly connected to the fixing bolt 3. When the clamping member 41 is clamped to the disk body 51, the threaded hole 52 is connected to the clamping space 42. In other words, the fixing bolt 3 can be extended into the clamping space 42 through the threaded hole 52, that is, the connector 5 is made into a nut-like shape, and the threaded hole 52 passes through the connector 5. It can adapt to a long fixing bolt 3 without increasing the length of the connector 5, thereby improving the connection strength. After clamping, the fixing bolt 3 can be extended into the clamping space 42, reducing the difficulty of installation and avoiding interference between the fixing bolt 3 and the connector 5. In this embodiment, by setting the connector 5 to an axisymmetric shape, it can be convenient for processing and manufacturing, and the accurate positioning of the side edges can be ensured.

[0046] See also Figure 1As shown, preferably, the front door inner triangular cover 4 includes a triangular cover body 43; one end of the clamping claw 411 is fixed to the triangular cover body 43, and the end of the clamping claw 411 away from the triangular cover body 43 is provided with an anti-slip protrusion 412; when the clamping member 41 is clamped with the connector 5, the anti-slip protrusion 412 is located at the end of the disc 51 away from the triangular cover body 43, and the anti-slip protrusion 412 abuts against the end face of the disc 51 away from the triangular cover body 43. In other words, by providing the anti-slip protrusion 412 at the end of the clamping claw 411 away from the triangular cover body 43, wherein the anti-slip protrusion 412 is provided on the side of the clamping claw 411 close to the clamping space 42, the anti-slip protrusion 412 prevents the disc 51 from falling off the clamping member 41 along the direction in which the clamping claw 411 extends, thereby achieving the positioning of the connector 5 and the front door inner triangular cover 4 in the vehicle width direction. In this embodiment, the anti-slip protrusion 412 is in the shape of a triangle. In other embodiments, the anti-slip protrusion 412 may also be in the shape of a rectangle or other shapes.

[0047] See also Figure 1 As shown, preferably, the claw 411 is provided with a reinforcing rib 44. Since the clamping process of the claw 411 requires elastic deformation, in order to ensure that the claw 411 is tightly clamped, a reinforcing rib 44 is provided at the claw 411 to avoid deformation or damage of the claw 411 and to improve the strength of the claw 411. Among them, the claws 411 of the clamping member 41 can be rod-shaped and spaced apart from each other, so that they can deform and clamp the disc 51 of the connector 5 during the clamping process. In other embodiments, the claws 411 can also be petal-shaped or enclosed in a barrel, which has better connection strength and is more tightly clamped. In this embodiment, by providing the reinforcing rib 44 on the claw 411 of the rod-shaped structure, the clamping of the claw 411 is achieved, and the clamping is relatively easy, and will not cause too much trouble to the clamping installation.

[0048] See also Figure 1 As shown, the reinforcing rib 44 is preferably located on the side of the claw 411 away from the engaging space 42. In other words, the reinforcing rib 44 is provided on the outside of the claw 411 to secure the claw 411 to the connecting body 5 after the claw 411 expands outward to engage the connecting body 5. Furthermore, compared to providing the rib within the engaging space 42, providing the rib outside the engaging space 42 is simpler and does not affect the insertion of the fixing bolt 3 into the engaging space 42.

[0049] See also Figure 1 As shown, preferably, the claws 411 of the clamping member 41 are evenly spaced along the circumferential direction. That is, by adapting the circumferentially arranged claws 411 to the disc 51 of the connector 5, the front door inner triangular cover 4 can be rotated relative to the connector 5 after being engaged. Furthermore, by evenly spacing the claws 411 along the circumferential direction, the side edges of the disc 51 are subjected to the same strong clamping force, thereby achieving a better clamping effect.

[0050] See also Figure 8 As shown, in some preferred embodiments, the outer hoop of the clamping member 41 is provided with a hoop body 6, and the hoop body 6 is simultaneously provided outside all the claws 411. Each claw 411 is provided with a limiting groove 415 on the side away from the anti-slip protrusion 412, and the hoop body 6 is clamped at the limiting groove 415. In other words, by providing the hoop body 6 on the outer side of the clamping member 41, the clamping strength of the clamping member 41 is improved by the hoop body 6. By providing the hoop body 6 at the limiting groove 415 on the side away from the anti-slip protrusion 412, the deviation of the hoop body 6 is reduced, and the anti-slip protrusion 412 can be accurately clamped, thereby improving the clamping effect of the anti-slip protrusion 412.

[0051] See also Figure 9 As shown, in some optional embodiments, the exterior rearview mirror 2 includes a housing 21, on which a mirror body is mounted. The fixing bolt 3 is fixed to the housing 21. The housing 21 is provided with an air jet passage 211 extending to the fixing bolt 3, the air jet passage 211 facing the working surface of the mirror body. The fixing bolt 3 is provided with an air hole 33 extending through the fixing bolt 3, the air hole 33 being connected to the air jet passage 211. The end of the fixing bolt 3 distal from the housing 21 extends out of the connector 5 and is connected to the air jet pipe 7. The air hole 33 is connected to the high-pressure air pump through the air jet pipe 7. In other words, by providing the air jet passage 211 in the housing 21 and connecting it to the high-pressure air pump via the fixing bolt 3, when moisture forms on the mirror body of the exterior rearview mirror 2, air is pumped out by the high-pressure air pump. The high-pressure air flows through the air jet pipe 7 to the air hole 33 in the fixing bolt 3, and finally to the air jet passage 211 and is blown toward the working surface of the mirror body, thereby cleaning the mirror body and facilitating cleaning of the exterior rearview mirror 2 while driving. The housing 21 may be provided with a threaded mounting hole, through which the fixing bolt 3 is mounted on the housing 21. The threaded mounting hole is connected to the air jet passage 211, so that after the fixing bolt 3 is installed, the air hole 33 is connected to the air jet passage 211. The air jet pipe 7 may be directly mounted on the end of the fixing bolt 3, or may be installed via a pipe joint threadedly connected to the fixing bolt 3.

[0052] See also Figure 1As shown, preferably, a first inclined surface 413 is provided at one end of the anti-slip protrusion 412 away from the triangular cover body 43; as the anti-slip protrusion 412 approaches the disc 51, the first inclined surface 413 gradually deviates toward the axis of the engaging space 42. In other words, the first inclined surface 413 gradually tilts from the distal end of the anti-slip protrusion 412 toward the engaging space 42. The first inclined surfaces 413 of the multiple anti-slip protrusions 412 form a tapered opening with a large opening and a gradually decreasing inner diameter. The tapered opening formed by the first inclined surfaces 413 can guide the disc 51 into the engaging space 42. When the disc 51 is engaged along the axis of the engaging space 42, the outer edge of the disc 51 gradually expands the claw 411 outward along the first inclined surface 413. Until the disc 51 passes over the first inclined surface 413, the outward expansion of the claw 411 decreases. Since the outward expansion of the claw 411 can be achieved through axial movement, the clamping can be achieved by only moving the clamping part 41 axially close to the disk body 51 during the installation process. Compared with setting the end of the claw 411 as a plane and manually prying the claw 411 open for clamping, the clamping process guided by the first inclined surface 413 is simpler.

[0053] See also Figure 1 As shown, preferably, the anti-slip protrusion 412 is provided with a second inclined surface 414 at one end close to the triangular cover body 43; along the direction in which the anti-slip protrusion 412 approaches the disc body 51, the second inclined surface 414 gradually deviates away from the axis of the clamping space 42. Similar to the first inclined surface 413, the second inclined surface 414 is provided to facilitate the removal of the clamping member 41 after clamping. By utilizing the characteristic of the second inclined surface gradually expanding outward when approaching the triangular cover body 43, the anti-slip protrusion 412 at the end of each claw 411 will form a shape with a small opening and a large interior in the second inclined surface 414 section, thereby achieving an effect of easy exit and difficult entry. When the disc body 51 is moved out of the clamping space 42, the disc body 51 moves away from the triangular cover body 43 along the axis of the clamping space 42, and the outer edge of the disc body 51 presses against the second inclined surface 414 to expand the claw 411 outward. When the axial force is sufficient, the disc body 51 can be pulled out of the clamping space 42. Compared to most claw structures that are arranged perpendicular to the plane of the claw structure, the second inclined surface 414 of this embodiment reduces the difficulty of manually removing the clamping member 41. Figure 1 As shown, the cross section of the anti-slip protrusion is similar to a trapezoid, and the two bottom angles of the trapezoid are both acute angles, so that the two inclined surfaces of the trapezoid can respectively achieve the effect of guiding insertion and guiding extraction. In other embodiments, the anti-slip protrusion 412 can also be set to an acute triangle, which can also achieve the clamping guidance effect.

[0054] See also Figure 1 and Figure 2As shown, preferably, the fixing bolt 3 includes a positioning block 31, one end of which is fixedly connected to the exterior rearview mirror 2. The positioning block 31 is located outside the triangular lining 1, and its end face abuts the triangular lining 1. A stud 32 is provided on the end of the positioning block 31 away from the exterior rearview mirror 2, and the stud 32 is threadedly connected to the weld nut 11 fixed to the triangular lining 1. In other words, the fixing bolt 3 is first installed on the triangular lining 1, wherein the end face of the positioning block 31 abuts the triangular lining 1 to achieve positioning in the vehicle width direction. This is simpler than positioning the exterior rearview mirror 2 by abutting the triangular lining 1 with the entire surface. Then, the connector 5 is threadedly connected to the fixing bolt 3, and the front door inner triangular cover 4 is clamped to the connector 5 by snap-fitting. This solves the problem of the fixing bolt 3 end being unable to pass through the triangular lining 1 while installing the connector 5, while also ensuring the positioning of the exterior rearview mirror 2 in the vehicle width direction. In this embodiment, the positioning block 31 is located on the outside of the vehicle, which reduces the space occupied by the triangular area on the inside and facilitates the installation of the front door inner triangular cover 4. In this embodiment, the triangular inner panel 1 is threadedly connected to the fixing bolt 3 via a weld nut 11. In other embodiments, the triangular inner panel 1 can be partially thickened to form a boss, and threaded holes can be provided to achieve the threaded connection of the fixing bolt 3.

[0055] The principle of the fixing structure of the front door inner triangle cover provided by the embodiment of the present invention is as follows:

[0056] The exterior mirror 2 is secured to the exterior side of the triangular lining 1 via fixing bolts 3. The portion of the fixing bolts 3 extending into the interior side is threadedly connected to the connector 5, achieving a shared mounting location. The interior front door triangular lining 4 is mounted on the interior side by means of a clip 41 that engages the connector 5. By sharing a common mounting location, both components can be mounted on the top area of the triangular lining 1, ensuring a secure fit. Furthermore, this eliminates the need to occupy the guide rails of the triangular lining 1, effectively preventing the glass run from being affected by the rails and reducing the vehicle's NVH performance. The exterior mirror 2 is directly secured to the exterior side of the triangular lining 1 via fixing bolts 3, allowing for greater force transfer to the triangular lining 1 and accommodating the heavier exterior mirror 2. The interior front door triangular lining 4 is secured to the connector 5 via a clip, and then secured to the interior side of the triangular lining 1 via the connector 5 through threaded connection with the fixing bolts 3. This simplifies installation and is particularly suitable for the relatively lightweight interior front door triangular lining 4, which often requires limited installation space.

[0057] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper" and "lower" is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be internal communication between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0058] It should be noted that, in the present invention, relational terms such as "first" and "second" are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply the existence of any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.
