Description

Technical Field

[0001] This invention relates to the automotive field, specifically to an exterior rearview mirror assembly and a vehicle. Background Technology

[0002] In the prior art, a car door generally includes an inner door panel and an outer door panel. Due to the influence of stamping and welding processes, there are generally fixed manufacturing tolerances and dimensional deviations between the inner door panel and the outer door panel.

[0003] Exterior rearview mirrors are typically positioned on the inner door panel of the front door, while surrounding components that have a clearance-surface difference fit with the exterior rearview mirrors use the outer door panel as their positioning reference. The positioning of these components relies on two different sheet metal parts—the inner and outer door panels—resulting in an increased number of dimensional links. To meet DTS (Design for Quality) requirements, it is necessary to improve the manufacturing precision of these components, thereby increasing production costs.

[0004] Therefore, the existing exterior rearview mirror mounting structure has a technical defect of a long dimension chain; so in order to improve the above problems, it is necessary to optimize the design of the existing exterior rearview mirror mounting structure. Summary of the Invention

[0005] The purpose of this invention is to provide a rearview mirror assembly that can reduce the assembly dimension chain between the exterior rearview mirror and surrounding components.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] An exterior rearview mirror assembly includes a rearview mirror body and a support; the support is connected to a vehicle door via a mounting structure; the mounting structure includes a first mounting structure, a second mounting structure, and a third mounting structure disposed on the support; the support is connected to the inner panel of the vehicle door via the first mounting structure; the support is connected to the outer panel of the vehicle door via the second and third mounting structures; the first, second, and third mounting structures jointly constrain the degrees of freedom between the support and the vehicle door along a first direction, a second direction, and a third direction, respectively.

[0008] The second direction and the third direction are both different from the first direction; the first mounting structure limits the support along the first direction, the second mounting structure limits the support along the second direction, and the third mounting structure limits the support along the third direction.

[0009] The first mounting structure includes mounting holes provided on the support; the support is connected to the inner panel of the door by fasteners passing through the mounting holes; the mounting holes and fasteners are clearance-fitted.

[0010] The second mounting structure includes a locating pin disposed on the support;

[0011] The third mounting structure includes a snap-fit ​​mechanism and / or an adhesive mechanism mounted on the support.

[0012] The first mounting structure includes three spaced-apart mounting holes; the third mounting structure includes two spaced-apart snap-fit ​​mechanisms.

[0013] The support includes a transverse support and a longitudinal support, which are arranged intersecting each other; the first mounting structure is disposed on the longitudinal support; the second mounting structure and the third mounting structure are disposed on the transverse support.

[0014] The lateral support includes a first support and a second support. The first support is connected to the rearview mirror body through the second support, and the first support and the second support are intersecting. The horizontal projection of the lateral support is T-shaped.

[0015] The transverse support end is provided with a water-cutting positioning mechanism, which includes a protruding insert provided at the end of the transverse support.

[0016] The protruding insert is provided with a snap-fit ​​inner groove; the positioning pin in the second mounting structure is frustoconical; the snap-fit ​​mechanism in the third mounting structure includes a buckle provided on the support.

[0017] The bonding mechanism in the third mounting structure includes an adhesive layer disposed on the support.

[0018] A vehicle includes a door, an exterior door water cutter, and an exterior rearview mirror assembly; the door includes an inner door panel and an outer door panel; the inner door panel has fixing holes, each fixing hole corresponding to a mounting hole; the outer door panel includes an outer panel body, the outer panel body has an outer panel flange; the outer panel flange has positioning holes.

[0019] The support is inserted into the positioning hole through the second mounting structure; the support is connected to the outer plate flange through the third mounting structure;

[0020] The outer water-cut end of the vehicle door is provided with a recessed insertion groove; the protruding insert in the outer rearview mirror assembly is inserted into the recessed insertion groove at the outer water-cut end of the vehicle door.

[0021] The outer panel body is provided with an overlap notch; the outer rearview mirror assembly overlaps in the overlap notch of the outer panel body; the two snap-fit ​​mechanisms in the outer rearview mirror assembly are distributed on both sides of the overlap notch;

[0022] The longitudinal support in the exterior rearview mirror assembly is inserted into the door; the longitudinal support has an overlapping groove on the side near the outer panel body; the longitudinal support can be connected to the outer panel body through the overlapping groove.

[0023] The advantages of this invention are:

[0024] This invention discloses an exterior rearview mirror assembly and a vehicle.

[0025] This invention shifts the positioning reference of the exterior rearview mirror from the traditional inner door panel to the outer door panel, so that the final assembly position of the rearview mirror directly depends on the visible outer panel, fundamentally eliminating the transmission of dimensional fluctuations caused by welding tolerances between the inner and outer door panels.

[0026] Meanwhile, the first mounting structure, the second mounting structure, and the third mounting structure constrain the degrees of freedom in different directions respectively; the first mounting structure achieves a tight fit between the exterior rearview mirror assembly and the inner door panel in the first direction; while in the second and third directions, the floating amount is released and limited by the outer door panel; so that the gap and surface difference tolerance between the exterior rearview mirror assembly and the door and door accessories are stably controlled within ±0.5mm.

[0027] The second and third mounting structures of the present invention are directly matched with the outer door panel, which directly links the matching state of the exterior rearview mirror with the outer door panel, thus greatly reducing the number of size chain links.

[0028] Meanwhile, the protruding insert at the rear end of the rearview mirror bracket directly engages with the outer water cutter of the door, further shortening the dimensional chain between the exterior rearview mirror and the outer water cutter of the door, so that the surface difference between the two is controlled within ±0.7mm.

[0029] The first mounting structure of this invention ensures the strong fastening connection between the rearview mirror and the inner door panel. The second and third mounting structures independently control the precise position of the rearview mirror in the other two directions, which not only ensures the reliability of the assembly connection, but also achieves independent optimization of the positioning accuracy in each direction, overcoming the defect of traditional structures that are difficult to balance due to the mutual coupling of positioning in each direction.

[0030] This invention enables a stable fit between the exterior rearview mirror and the outer door panel through the contact surface of the third mounting structure, eliminating the problem of large gap fluctuations between the bottom of the rearview mirror and the outer panel in the traditional structure; the rearview mirror is directly connected to the water cutter through the extended insert, so that the fit between the outer water cutter and the rearview mirror is not affected by the relative size fluctuations of the inner and outer door panels, and the refinement of the local appearance matching of the whole vehicle is significantly improved.

[0031] The first, second, and third mounting structures of this invention can all be implemented using conventional bolt connections, locating pin insertions, and adhesive strip bonding methods. No complex parts or special processes are required, and they can be implemented under existing car door production lines and equipment conditions, exhibiting good process inheritance and economy.

Detailed Implementation

[0043] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.

[0044] An exterior rearview mirror assembly 1 includes a rearview mirror body 12 and a support 11. The support 11 is connected to a vehicle door 3 via a mounting structure. The mounting structure includes a first mounting structure, a second mounting structure, and a third mounting structure disposed on the support 11. The support 11 is connected to the inner door panel 32 of the vehicle door 3 via the first mounting structure. The support 11 is connected to the outer door panel 31 of the vehicle door 3 via the second and third mounting structures. The first, second, and third mounting structures jointly constrain the degrees of freedom between the support 11 and the vehicle door 3 along the first, second, and third directions, respectively. This invention, by transferring the positioning reference of the exterior rearview mirror from the traditional inner door panel 32 to the outer door panel 31, makes the final assembly position of the rearview mirror directly depend on the visible outer panel, fundamentally eliminating the dimensional fluctuation transmission caused by welding tolerances between the inner door panel 32 and the outer panel.

[0045] In this invention, the first direction is the Y-direction (vehicle width direction); the second direction is the X-direction (vehicle length direction); and the third direction is the Z-direction (vehicle height direction).

[0046] The rearview mirror body 12 serves as both an aesthetic and functional component, providing a field of vision. Its final spatial position is determined by the support 11. The support 11 is the core connecting hub, supporting the rearview mirror body 12 at one end and connecting to the door 3 at the other end via a mounting structure. The inner door panel 32 serves as a strength component of the door 3, primarily responsible for providing the fastening torque and structural support at the mounting point; the outer door panel 31 serves as a styling surface component of the door 3, primarily responsible for providing the positioning reference for aesthetic matching.

[0047] The first mounting structure is mounted on the support 11 and is threadedly fastened to the mounting point on the inner door panel 32 by fasteners passing through the mounting holes 13. In terms of spatial constraints, this structure fits tightly with the inner door panel 32 in the first direction, providing the main anti-dislodgement clamping force through bolt tightening and precisely controlling the position of the rearview mirror in the vehicle width direction; at the same time, there is a floating amount in the second and third directions, that is, the fasteners and mounting holes 13 are in clearance fit, the function of which is to actively release the constraints in these two directions, avoiding the internal stress caused by the forced assembly of the rearview mirror due to the manufacturing tolerance between the inner door panel 32 and the outer panel; at the same time, it can also effectively avoid installation interference between the outer rearview mirror assembly 1 and the outer door panel 31.

[0048] The second mounting structure is mounted on the support 11, typically in the form of a locating pin 14, which is inserted into a corresponding locating hole 34 on the outer door panel 31. This structure is mainly used to constrain the position of the exterior rearview mirror assembly 1 in the second direction. Through the cooperation of the locating pin 14 and the locating hole 34, the position of the rearview mirror in the front-rear direction of the vehicle is precisely controlled, ensuring that the gap between the rearview mirror and the door and fender is uniform in the front-rear direction. Since the positioning reference is directly taken from the outer door panel 31, the positioning accuracy in this direction is no longer affected by the welding deviation of the inner door panel 32.

[0049] The third mounting structure is located at the bottom of the support 11 and includes a clip 15 and an adhesive layer 17. The adhesive layer 17 directly rests on the outer edge 312 of the outer door panel 31 to achieve a close fit and positioning. The clip 15 hooks onto the lower edge of the outer edge 312 of the outer door panel 31 from below. The third mounting structure is mainly used to constrain the position of the exterior rearview mirror assembly 1 in the third direction. The direct contact between the adhesive layer 17 and the outer door panel 31, combined with gravity and the pre-tightening effect of the clip 15, precisely controls the position of the rearview mirror in the vehicle height direction, ensuring a stable surface difference between the bottom of the rearview mirror and the door triangular window and window sill line. This fundamentally solves the problem of unstable vertical position of the rearview mirror caused by fluctuations in the dimensions of the inner and outer panels in traditional structures.

[0050] The first mounting structure, the second mounting structure, and the third mounting structure together constrain the degrees of freedom between the support 11 and the door 3 along the first direction, the second direction, and the third direction, respectively, forming a complete six-degree-of-freedom constraint system, but with a differentiated allocation strategy.

[0051] In the first direction, the first mounting structure is responsible for achieving complete fixation and constraint by tightening bolts. The positioning reference is derived from the inner door panel 32, which mainly provides clamping force.

[0052] In the second direction, the second mounting structure is responsible for achieving precise positioning through the single-point engagement of the positioning pin 14 and the positioning hole 34. The positioning reference is derived from the outer door panel 31, which mainly determines the position of the rearview mirror in the front and rear directions of the vehicle.

[0053] In the third direction, the third installation structure is responsible for achieving precise positioning through the surface support and snap-fit ​​mechanism of the outer panel flange 312. The positioning reference is also derived from the outer panel 31 of the door, which mainly determines the position of the rearview mirror in the vehicle height direction.

[0054] Traditional rearview mirror mounts have an inner panel with two pins on one side. The X / Z datum is taken from the inner panel, and the tolerance chain between the inner and outer panels is transferred to the rearview mirror, causing the assembly accuracy to be affected by the double tolerances of the inner and outer panels. This solution releases floating amount in the second and third directions through the first mounting structure, actively interrupting the rigid transmission path of tolerance from the inner panel to the rearview mirror, and avoiding assembly problems caused by over-positioning.

[0055] The positioning references for the second and third directions, which determine the accuracy of the appearance matching, are transferred from the invisible inner door panel 32 to the visible outer door panel 31. This makes the final assembly position of the rearview mirror directly dependent on the appearance surface, significantly improving the matching accuracy and reducing the tolerance band by approximately 0.4mm compared to the traditional structure.

[0056] During assembly, the positioning pin 14 of the second mounting structure is first inserted into the positioning hole 34 of the outer door panel 31 to guide the assembly. The buckle 15 of the third mounting structure hooks onto the outer door panel 31 to achieve Z-axis positioning. Finally, the bolts of the first mounting structure are tightened. This assembly sequence of positioning first and then tightening can ensure accuracy, reduce assembly difficulty, and facilitate operation by production line workers.

[0057] The first mounting structure is responsible for locking in the first direction and transmitting the fastening force, but actively releases the degree of freedom in the second and third directions; the second and third mounting structures take over the positioning control in the second and third directions respectively, and the positioning reference is taken entirely from the outer door panel 31. The whole solution can be summarized as follows: using the fastening force provided by the inner door panel 32 in conjunction with the positioning reference provided by the outer door panel 31, the rearview mirror is precisely fixed in the designed position.

[0058] In this invention, the second direction and the third direction are both different from the first direction; the second direction and the third direction are both different from the first direction; the first mounting structure limits the support 11 along the first direction, the second mounting structure limits the support 11 along the second direction, and the third mounting structure limits the support 11 along the third direction; through the above design, the first direction, the second direction, and the third direction of this invention are spatially different from each other. In the vehicle coordinate system, the first direction is the vehicle Y-direction (vehicle width direction), the second direction is the vehicle X-direction (vehicle length direction), and the third direction is the vehicle Z-direction (vehicle height direction). The first direction, the second direction, and the third direction are perpendicular to each other, forming a complete spatial rectangular coordinate system. The first mounting structure, the second mounting structure, and the third mounting structure together constitute a complete six-degree-of-freedom constraint system, but a differentiated constraint allocation strategy is adopted; in the first direction, the first mounting structure alone undertakes the limiting function, and rigid fixation is achieved by tightening bolts, so that the support 11 has no relative displacement in the first direction. In the second direction, the second mounting structure undertakes the main limiting function, and the cooperation between the positioning pin 14 and the positioning hole 34 precisely controls the position of the support 11 in the second direction; the first mounting structure releases its degree of freedom in this direction and does not participate in the limiting, thus avoiding over-positioning caused by double constraints.

[0059] In the third direction, the third mounting structure undertakes the main limiting function, and the combined use of the adhesive mechanism and the snap-fit ​​mechanism precisely controls the position of the support 11 in the third direction; the first mounting structure also releases the degree of freedom in this direction and does not participate in the limiting function.

[0060] Specifically, in this invention, the first mounting structure includes a mounting hole 13 provided on the support 11; the support 11 is connected to the inner door panel 32 by a fastener passing through the mounting hole 13; the mounting hole 13 and the fastener are clearance-fitted; the first mounting structure includes a mounting hole 13 provided on the support 11. The support 11 is connected to the inner door panel 32 by a fastener passing through the mounting hole 13, that is, a bolt (or screw) passes through the mounting hole 13 on the support 11 and is screwed into the corresponding fixing hole 33, nut plate, or weld nut on the inner door panel 32 to achieve a tight connection between the support 11 and the inner door panel 32. The mounting hole 13 and the fastener are clearance-fitted, that is, the diameter of the mounting hole 13 is larger than the diameter of the fastener rod, so that after the fastener passes through the mounting hole 13, there is a movable clearance in both directions within the plane of the mounting hole 13.

[0061] The mounting holes 13 are all round or oblong holes, with a diameter larger than the diameter of the fastener rod. The clearance on one side is preferably 1.2mm to 2.0mm. The mounting holes 13 correspond to the mounting points (fixing holes 33) on the inner door panel 32. By tightening three bolts simultaneously, a rigid connection between the support 11 and the inner door panel 32 is achieved.

[0062] The main functions of the first mounting structure are as follows: to limit the support 11 along the first direction (Y direction / vehicle width direction). By tightening the bolts, the corresponding mating surfaces of the support 11 and the inner door panel 32 are tightly fitted in the first direction, achieving a rigid fixed connection, precisely controlling the position of the exterior rearview mirror assembly 1 in the vehicle width direction, and providing the main anti-detachment clamping force.

[0063] The support 11 is freed in the second direction (X-direction / vehicle length direction) and the third direction (Z-direction / vehicle height direction). The clearance fit between the mounting hole 13 and the fastener means that the bolt shank can move freely in both the second and third directions within the mounting hole 13. That is, after the bolt is tightened, the support 11 is not fixed by the bolt in the second and third directions and is in a floating state. This active release of freedom design avoids forcibly transferring the manufacturing tolerances of the inner door panel 32 in the second and third directions to the support 11.

[0064] The second mounting structure includes a locating pin 14 disposed on the support 11. The locating pin 14 is disposed on the lower surface of the support 11 and is used to engage with a corresponding locating hole 34 disposed on the outer door panel 31. The cross-sectional shape of the locating pin 14 can be circular, square, or cross-shaped, and its size is basically the same as the inner diameter of the locating hole 34, with a small clearance fit between them.

[0065] However, in actual implementation, a frustum or truncated cone shape can be selected. This setting can achieve the lowering limit of the exterior rearview mirror assembly 1.

[0066] The second mounting structure primarily limits the support 11 along the second direction (X-direction / vehicle length direction). When the locating pin 14 is inserted into the locating hole 34 of the outer door panel 31, the outer wall of the locating pin 14 and the inner wall of the locating hole 34 form a contact fit in the second direction, precisely limiting the degree of freedom of movement of the support 11 in the second direction. Through this fit, the position of the exterior rearview mirror assembly 1 in the vehicle's longitudinal direction is precisely determined, ensuring that the clearance between the exterior rearview mirror and the door and fender in the longitudinal direction is uniform.

[0067] The positioning reference is directly taken from the outer door panel 31. The positioning pin 14 directly cooperates with the positioning hole 34 on the outer door panel 31, so that the positioning of the rearview mirror in the second direction is directly determined by the outer door panel 31, no longer affected by the welding tolerance of the inner door panel 32, fundamentally shortening the dimensional chain.

[0068] During assembly, the exterior rearview mirror assembly 1 is installed from top to bottom. The positioning pin 14 first enters the positioning hole 34, providing guidance for subsequent assembly actions and reducing the difficulty of operation.

[0069] The third mounting structure includes a snap-fit ​​mechanism and / or an adhesive mechanism disposed on the support 11.

[0070] The third mounting structure includes a snap-fit ​​mechanism mounted on the support 11. The snap-fit ​​mechanism mainly includes a latch 15, which is a resilient snap-fit ​​point, typically a plastic or metal elastic arm extending from the bottom side of the support 11, with a barb structure at the end for snapping onto the lower edge of the door outer panel 31 from below. The third mounting structure includes two spaced-apart snap-fit ​​mechanisms, respectively located at the front and rear ends of the support 11, with both snap-fit ​​points simultaneously engaging with the door outer panel 31.

[0071] In addition, the third mounting structure includes an adhesive mechanism disposed on the support 11; the adhesive mechanism mainly includes an adhesive layer 17 disposed on the support 11, the adhesive layer 17 can be attached to the outer panel flange 312; through the adhesion of the adhesive layer 17, the longitudinal position of the exterior rearview mirror assembly 1 can also be limited; that is, the adhesive layer 17 can be attached to the outer panel flange 312; through the adhesion of the adhesive layer 17, the position of the exterior rearview mirror assembly 1 in the third direction (Z direction) can be assisted in limiting the position of the exterior rearview mirror assembly 1.

[0072] In this invention, the third mounting structure snap-fit ​​mechanism and the adhesive mechanism can be used separately or in combination.

[0073] The function of the third mounting structure is to limit the position of the support 11 along the third direction (Z direction / vehicle height direction). The lower end of the support 11 is bonded to the outer panel flange 312 through the adhesive layer 17; in conjunction with the downward sinking of the support 11 itself and the pre-tightening force of the snap-fit ​​mechanism, the position of the rearview mirror in the vehicle height direction is precisely controlled, ensuring that the surface difference between the bottom of the rearview mirror and the door triangular window and window sill line is stable, and achieving a zero-attach matching effect.

[0074] The first, second, and third mounting structures are structurally independent but functionally coordinated, forming a complete differentiated constraint system. The locating pin 14 is first inserted into the locating hole 34 to complete the X-axis coarse positioning; then the locking point hooks onto the lower edge of the outer panel flange 312 of the door outer panel 31 to complete the Z-axis positioning; finally, the bolts are tightened to complete the Y-axis fastening. The entire assembly process is smooth and efficient. Each of the three mounting structures undertakes an independent directional constraint function.

[0075] In this invention, the first mounting structure includes three spaced mounting holes 13. These mounting holes 13 are primarily located on the longitudinal support 112. The three mounting holes 13 are arranged in a triangular pattern, meaning they are not collinear in space, forming a geometric triangle. Each mounting hole 13 is either round or oblong, with a diameter larger than the diameter of the fastener (bolt) shank, allowing for a movable clearance in both directions within the plane of the mounting hole 13 after the fastener passes through it. Each mounting hole 13 corresponds to a mounting point (fixing hole 33) on the inner door panel 32. Three bolts pass through the three mounting holes 13 and are screwed into the fixing holes 33 on the inner door panel 32, thus securing the support 11 to the inner door panel 32.

[0076] The third mounting structure described in this invention includes two spaced-apart snap-fit ​​mechanisms. These two snap-fit ​​mechanisms are located at the bottom of the support 11, at the front and rear ends of the support 11 respectively (i.e., the ends closer to the front and rear of the vehicle in the front-rear direction). Each snap-fit ​​mechanism includes a buckle 15, which is an elastic snap-fit ​​component, typically made of plastic or metal with an elastic arm structure and a barb at its end. During assembly, the two buckles 15 are inserted from above into the gap between the inner door panel 32 and the outer panel, passing through the lower edge of the outer panel flange 312, and then the barb snaps against the lower edge of the outer panel flange 312 from below, forming a snap-fit ​​connection. The distance between the two snap-fit ​​mechanisms in the front-rear direction is determined according to the actual dimensions of the bottom of the support 11.

[0077] Furthermore, in this invention, the support 11 includes a transverse support 111 and a longitudinal support 112, which are intersecting. The first mounting structure is disposed on the longitudinal support 112; the second and third mounting structures are disposed on the transverse support 111. The longitudinal support 112 is disposed on the transverse support 111. Based on this design, the main projection of the support 11 forms a tilted L-shaped structure, which facilitates the attachment of the support 11 to the door 3. The transverse support 111 and the longitudinal support 112 are intersecting, forming a cross connection in space. In terms of specific structural form, the longitudinal support 112 extends along the vehicle height direction (Z-direction), and the transverse support 111 extends along the vehicle width direction (Y-direction). The two are fixedly connected at their intersection point to form an integral support frame. The longitudinal support 112 serves as the main structural connector between the exterior rearview mirror assembly 1 and the door 3, and is inserted into the gap between the inner panel 32 and the outer panel of the door; the transverse support 111 is located outside the door 3, supporting the rearview mirror body 12 and providing related structures for appearance matching.

[0078] The first mounting structure is mounted on the longitudinal support 112. The longitudinal support 112 extends along the Z-direction, with its inner surface facing the inner door panel 32. Three spaced mounting holes 13 are provided on the longitudinal support 112. The mounting holes 13 are laterally inserted through the longitudinal support 112. When the longitudinal support 112 is inserted into the gap between the inner door panel 32 and the outer panel, the three mounting holes 13 are aligned with the corresponding fixing holes 33 on the inner door panel 32. The longitudinal support 112 and the inner door panel 32 are then fastened together along the Y-direction by three bolts.

[0079] The second and third mounting structures are mounted on the transverse support 111. The transverse support 111 is located outside the door 3, with its bottom surface facing the outer panel flange 312 of the outer door panel 31. The positioning pin 14 of the second mounting structure extends from the lower surface of the transverse support 111; the third mounting structure is located on the bottom side of the transverse support 111, with two clips 15 extending from the bottom side of the transverse support 111 and fastening to the lower edge of the outer panel flange 312.

[0080] The longitudinal support 112 is mainly responsible for the fastening connection with the inner door panel 32, while the transverse support 111 is mainly responsible for the positioning and cooperation with the outer door panel 31.

[0081] In this invention, the lateral support 111 includes a first support 1111 and a second support 1112. The first support 1111 is connected to the rearview mirror body 12 through the second support 1112, and the first support 1111 and the second support 1112 are intersecting. The horizontal projection of the lateral support 111 is T-shaped. The first support 1111 is the base part of the lateral support 111, and its bottom surface is fixedly connected to the longitudinal support 112. The lower side of the bottom surface is provided with a fitting surface, a snap-fit ​​point, and a positioning pin 14, etc., which cooperate with the outer door panel 31. The second support 1112 extends from the first support 1111 in the outward direction of the vehicle, and its end is connected to the rearview mirror body 12. The first support 1111 and the second support 1112 are intersecting in the horizontal projection, so that the horizontal projection of the lateral support 111 is T-shaped. The first support 1111 extends roughly along the vehicle's longitudinal direction (X-axis), and the second support 1112 extends outward from the middle of the first support 1111 along the vehicle's width direction (Y-axis), forming a T-shape in horizontal projection. The advantages of the T-shaped structure are: the outward extension of the second support 1112 provides sufficient support span for the rearview mirror body 12, allowing the rearview mirror to be positioned as designed; the first support 1111 extending along the X-axis provides space for the front and rear latches 15 and increases the contact area with the outer door panel 31, improving the stability of the Z-axis positioning and anti-overturning capability. At the same time, the intersection of the first support 1111 and the second support 1112 makes the transverse support 111 an integrated load-bearing structure, allowing the load to be smoothly transferred from the second support 1112 to the first support 1111, and then from the first support 1111 to the longitudinal support 112, resulting in a continuous and efficient force transmission path.

[0082] Furthermore, in this invention, a water-cutting positioning mechanism is provided at the end of the transverse support 111. This mechanism includes a protruding insert 16 at the end of the transverse support 111. The protruding insert 16 extends rearward from the end of the transverse support 111 near the rear of the vehicle (i.e., the rear of the vehicle) along the vehicle's longitudinal direction (X-direction), forming a cantilever structure. The protruding insert 16 is located at the rear end of the transverse support 111, and its thickness and width match the dimensions of the insertion groove 21 provided at the end of the outer water-cutting edge 2 of the door, allowing the protruding insert 16 to be smoothly inserted into the groove at the end of the water-cutting edge. By providing the protruding insert 16, the dimensional chain between the outer water-cutting edge and the rearview mirror is directly shortened. In this invention, the protruding insert 16 extends directly from the end of the rearview mirror transverse support 111, and the front end of the outer water-cutting edge directly engages with the protruding insert 16, allowing the position of the outer water-cutting edge to be directly determined based on the rearview mirror, significantly shortening the dimensional chain. The Y-axis surface difference between the outer water cutter 2 of the car door and the rearview mirror is precisely controlled by inserting the protruding insert 16 into the outer water cutter 2 of the car door; so that the end of the outer water cutter 2 of the car door is supported by the outer rearview mirror assembly 1, thereby ensuring that the surface difference between the outer water cutter 2 of the car door and the lateral support 111 meets the design requirements.

[0083] In addition, the depth (X direction) of the water-cutting end groove is further determined by the protruding insert 16; the position of the water-cutting front end is directly determined by the protruding insert 16, ensuring the gap and surface difference accuracy between the water-cutting front end and the rear end of the rearview mirror.

[0084] In this invention, the protruding insert 16 is provided with a snap-fit ​​inner groove 161. The snap-fit ​​inner groove 161 is located on the side of the protruding insert 16 and is in the form of a groove, used to form a snap-fit ​​with the protrusion 211 structure corresponding to the inner side of the water-cutting end insertion groove 21. The snap-fit ​​inner groove 161 provides a definite snap-fit ​​positioning point for the outer water-cutting. After the protrusion 211 corresponding to the water-cutting end insertion groove 21 is snapped into the snap-fit ​​inner groove 161 of the protruding insert 16, the water-cutting is constrained in both the Y and Z directions, which not only prevents the water-cutting from slipping out due to vibration during vehicle operation, but also ensures the stable engagement posture between the water-cutting end and the rearview mirror. During assembly, first snap the rear end of the outer water-cutting onto the edge surface of the outer door panel 31, and then insert the front end of the water-cutting into the protruding insert 16, so that the snap-fit ​​inner groove 161 engages with the protrusion in the insertion groove 21 to complete the assembly.

[0085] In this invention, the positioning pin 14 in the second mounting structure is frustum-shaped. Frustum-shaped means that the overall shape of the positioning pin 14 is a truncated cone or truncated pyramid, that is, the cross-sectional dimension of the positioning pin 14 gradually decreases from its root (the fixed end connected to the support 11) to its end (the insertion end into the positioning hole 34). Its root diameter is larger than its end diameter, and its outer wall forms a certain tapered slope. The end diameter of the positioning pin 14 is smaller than the inner diameter of the positioning hole 34 on the outer door panel 31, facilitating initial insertion. As the positioning pin 14 is gradually inserted into the positioning hole 34, the conical surface gradually contacts and guides the pin to the inner wall of the positioning hole 34. At the root region, the diameter of the positioning pin 14 is close to or essentially the same as the inner diameter of the positioning hole 34, achieving proper positioning.

[0086] The snap-fit ​​mechanism in the third mounting structure described in this invention includes a snap-fit ​​15 disposed on the support 11. The snap-fit ​​15 is an elastic snap-fit ​​element made of elastic plastic or metal material. Its specific structure is an elastic arm extending downward along the Z direction from the bottom side of the support 11, with a barb or protrusion at the end of the elastic arm. The elastic arm of the snap-fit ​​15 can elastically deform under external force. After the barb or protrusion penetrates the lower edge of the outer plate flange 312, it automatically resets and hooks the lower edge of the outer plate flange 312 from below.

[0087] In this invention, the bonding mechanism in the third mounting structure includes an adhesive layer 17 disposed on the support 11. The adhesive layer 17 is disposed on the mating surface corresponding to the outer panel flange 312 at the bottom of the support 11, that is, a layer of adhesive or double-sided tape with adhesive properties is coated or attached to the mating surface. The adhesive layer 17 can cover all or part of the mating surface, and its thickness is determined according to the type of adhesive material and the required bonding strength, typically 0.1 mm to 1.0 mm. The functional surface of the adhesive layer 17 is the mating surface between the support 11 and the outer door panel 31. During assembly, after the exterior rearview mirror assembly 1 is pressed into place, the adhesive layer 17 bonds and fixes the support 11 to the outer door panel 31.

[0088] A vehicle includes a door 3, an exterior door water cutter 2, and an exterior rearview mirror assembly 1; the door 3 includes an inner door panel 32 and an outer door panel 31; the inner door panel 32 has fixing holes 33, each fixing hole 33 corresponding to a mounting hole 13; the outer door panel 31 includes an outer panel body 311, the outer panel body 311 has an outer panel flange 312; the outer panel flange 312 has a positioning hole 34; a support 11 is inserted into the positioning hole 34 through a second mounting structure; the support... 11 is connected to the outer panel flange 312 via a third mounting structure; the end of the outer door water-cutter 2 is provided with an insertion groove 21; the protruding insert 16 in the outer rearview mirror assembly 1 is inserted into the insertion groove 21 at the end of the outer door water-cutter 2; the inner door panel 32 is the internal structural component of the door 3, providing structural strength and a mounting base; the outer door panel 31 is the outer panel of the door 3, forming the styling surface of the outer surface of the door 3; the outer door water-cutter 2 is a sealing decorative strip set along the lower edge of the window glass, located between the door 3 and the window glass. The three components are positioned and fastened to the outer rearview mirror assembly 1 through multiple connection points. The inner door panel 32 is provided with fixing holes 33. The fixing holes 33 are correspondingly provided with mounting holes 13 (i.e., each fixing hole 33 corresponds to one mounting hole 13), and the fastener passes through the mounting holes 13 to fix the support 11 to the inner door panel 32. Fixing holes 33 and mounting holes 13 form an array of mounting points on the inner door panel 32 for mating with the first mounting structure on the exterior rearview mirror assembly 1. The mounting holes 13 on the longitudinal support 112 in the first mounting structure are aligned with the fixing holes 33 on the inner door panel 32. Fasteners pass through the mounting holes 13 on the support 112 and connect to the fixing holes 33 on the inner door panel 32, achieving a rigid fastening connection between the exterior rearview mirror assembly 1 and the inner door panel 32 along the first direction (Y-direction / vehicle width direction). The fixing holes 33 (typically threaded holes or welded nuts) provide a base for bearing the fastening torque, and the mounting holes 13 provide a passage for the fasteners. The three fixing holes 33 and mounting holes 13 are arranged in a triangle, ensuring the stability of the fit and anti-overturning capability between the support 11 and the inner door panel 32 through three-point fastening. Meanwhile, since the mounting hole 13 on the support 11 and the fastener are clearance fit, the connection is free in the second direction (X direction / vehicle length direction) and the third direction (Z direction / vehicle height direction), allowing the exterior rearview mirror assembly 1 to float freely in these two directions, thus avoiding the transmission of the manufacturing tolerance of the inner panel to the exterior rearview mirror assembly 1.

[0089] The outer door panel 31 includes an outer panel body 311, on which an outer panel flange 312 is provided. The outer panel flange 312 is a flange structure formed by bending the outer door panel 31 at the window sill position, extending from the outer panel body 311 toward the inside of the door 3, forming a roughly horizontal support surface. The outer panel flange 312 is provided with positioning holes 34.

[0090] The support 11 of the exterior rearview mirror assembly 1 is inserted into the positioning hole 34 via a second mounting structure. The second mounting structure is a positioning pin 14 provided on the transverse support 111. The positioning pin 14 is inserted into the positioning hole 34 on the outer panel flange 312. The outer wall of the positioning pin 14 and the inner wall of the positioning hole 34 form a contact fit in the second direction (X direction / vehicle length direction), precisely restricting the degree of freedom of movement of the support 11 in the second direction. Since the positioning hole 34 is directly provided on the outer panel flange 312 of the door outer panel 31, the positioning reference of the exterior rearview mirror assembly 1 in the X direction is directly taken from the door outer panel 31, without being transmitted through the door inner panel 32, thereby eliminating the influence of the inner panel welding tolerance on the positioning accuracy in this direction.

[0091] The support 11 is also connected to the outer panel flange 312 via a third mounting structure. The third mounting structure includes an adhesive mechanism and a snap-fit ​​mechanism located at the bottom of the transverse support 111; the adhesive mechanism and the upper surface of the outer panel flange 312 form a fit in the third direction (Z direction / vehicle height direction), restricting the freedom of movement of the support 11 in the third direction; the snap-fit ​​mechanism (buckle 15) snaps against the lower edge of the outer panel flange 312 from below, providing a continuous Z-direction preload force, so that the adhesive layer 17 and the outer panel flange 312 maintain tight contact. The positioning reference of the third mounting structure is also directly taken from the door outer panel 31, so that the positioning of the exterior rearview mirror assembly 1 in the Z direction is not affected by the tolerance of the inner panel. Through the second mounting structure inserted into the positioning hole 34 and the third mounting structure connected to the outer panel flange 312, the exterior rearview mirror assembly 1 achieves bidirectional precise positioning with the outer panel as the reference in both the X and Z directions.

[0092] The outer water-cutting edge 2 of the vehicle door is provided with a recessed groove 21. The recessed groove 21 is located at the front end of the outer water-cutting edge near the front of the vehicle and is a recessed groove-shaped structure, which may have a protruding structure inside. The protruding insert 16 in the exterior rearview mirror assembly 1 is inserted into the recessed groove 21 at the end of the outer water-cutting edge 2 of the vehicle door. The protruding insert 16 extends from the rear end of the transverse support 111 along the X direction, and its shape matches the recessed groove 21. After insertion, it is fixed by engaging with the protrusion inside the recessed groove 21 through the snap-fit ​​inner groove 161.

[0093] The front end of the exterior water cutter 2 is directly connected to the lateral support 111 of the exterior rearview mirror assembly 1 via a plug-in connection, so that the position of the front end of the exterior water cutter is directly determined by the position of the exterior rearview mirror assembly 1. In this invention, the front end of the exterior water cutter 2 is directly engaged with the protruding insert 16 of the exterior rearview mirror assembly 1. The positioning of the exterior water cutter at the rearview mirror end is based on the rearview mirror, thereby cutting off the dimensional chain transmission path of this segment.

[0094] The assembly of the vehicle can be carried out in the following order.

[0095] First, assemble the exterior rearview mirror assembly 1 onto the door 3 from top to bottom, aligning the positioning pin 14 at the bottom of the transverse support 111 with the positioning hole 34 on the flange of the outer door panel 31 and inserting it. At the same time, the adhesive layer 17 at the bottom of the transverse support 111 contacts the flange 312 of the outer panel in the Z direction, and the buckle 15 moves past the lower edge of the flange 312 of the outer panel and then resets and hooks.

[0096] Next, align the mounting holes 13 on the longitudinal support 112 with the mounting holes 13 on the inner door panel 32, insert the fasteners and tighten them, so that the exterior rearview mirror assembly 1 and the inner door panel 32 are rigidly connected in the Y direction.

[0097] Finally, attach the rear end of the outer water cutter 2 of the car door to the outer water cutter edge of the car door 3, and then align the insertion groove 21 of the front end of the outer water cutter 2 of the car door with the protruding insert 16 at the end of the horizontal support 111 of the exterior rearview mirror assembly 1, and push it into the engagement groove 161 and the protrusion in the insertion groove 21 until they are engaged.

[0098] After the above assembly is completed, the entire system forms a complete constraint system. In the Y direction, the exterior rearview mirror assembly 1 is fastened to the inner door panel 32 through the first mounting structure (bolts), and the inner door panel 32 provides the Y-direction restraint force. In the X direction, the exterior rearview mirror assembly 1 engages with the positioning hole 34 on the flange of the outer door panel 31 through the second mounting structure (positioning pin 14), and the outer panel determines the X-direction position of the exterior rearview mirror assembly 1. In the Z direction, the exterior rearview mirror assembly 1 engages with the flange of the outer door panel 31 through the third mounting structure, and the outer panel determines the Z-direction position of the exterior rearview mirror assembly 1. At the same time, the front end of the exterior water cutter engages with the protruding insert 16 at the end of the exterior rearview mirror assembly 1 through the insertion groove 21, so that the X-direction and Z-direction positions of the front end of the exterior water cutter are based on the exterior rearview mirror assembly 1; the rear end of the exterior water cutter is engaged with the outer water cutter edge surface of the door 3, and the door 3 provides the rear end support. Ultimately, the surface difference between the outer water cutter and the rearview mirror is controlled within ±0.7mm, and the gap and surface difference tolerance between the rearview mirror and the door triangular window and surrounding accessories is controlled within ±0.5mm.

[0099] Furthermore, in this invention, the outer panel body 311 is provided with an overlap notch 313; the exterior rearview mirror assembly 1 overlaps in the overlap notch 313 of the outer panel body 311; the overlap notch 313 is a notch or opening area opened in the body of the outer panel 31 at the window sill position, located in a specific section of the outer panel flange 312. Specifically, the outer panel flange 312 does not extend continuously at the location corresponding to the installation position of the exterior rearview mirror assembly 1, but is interrupted to form a notch. The shape and size of this notch are selected as needed, generally matching the shape of the lower end face of the transverse support 111, to facilitate the subsequent overlap of the exterior rearview mirror assembly 1 in the overlap notch 313.

[0100] In this invention, the exterior rearview mirror assembly 1 overlaps in the overlap notch 313 of the outer panel body 311. Specifically, the intersection of the lateral support 111 and the longitudinal support 112 of the exterior rearview mirror assembly 1 is embedded in the overlap notch 313; the lateral support 111 covers and overlaps the edge of the notch from above, while the longitudinal support 112 extends through the overlap notch 313 into the interior of the door 3.

[0101] In this invention, the two snap-fit ​​mechanisms in the exterior rearview mirror assembly 1 are distributed on both sides of the overlap notch 313; the two latches 15 of the third mounting structure are respectively located at the front and rear ends of the bottom of the transverse support 111, outside the front and rear edges of the overlap notch 313 in the vehicle's longitudinal direction. The two snap-fit ​​mechanisms extend downwards from the bottom of the transverse support 111, pass through the outer panel flange 312, and snap onto its lower edge, forming snap-fit ​​points on both sides of the overlap notch 313. The two snap-fit ​​points are located near the two ends of the notch, with their spacing maximized. The greater the distance between the two snap-fit ​​points, the stronger the resistance to overturning moment.

[0102] Two snap-fit ​​mechanisms hook onto the lower edge of the outer panel flange 312 from both sides of the overlap notch 313, cooperating with the state of the transverse support 111 overlapping on the overlap notch 313. From above (the weight of the transverse support 111 and the bolt tension) and below (the snap-fit ​​force at the snap-fit ​​point), the Z-direction position of the support 11 relative to the outer panel 31 of the door is constrained simultaneously, forming a constraint effect similar to "clamping", making the Z-direction positioning more stable and reliable.

[0103] In this invention, the longitudinal support 112 in the exterior rearview mirror assembly 1 is inserted into the door 3; specifically, it is inserted into the gap between the inner door panel 32 and the outer door panel 31. The longitudinal support 112 has an overlapping groove 1121 on the side near the outer panel body 311. The longitudinal support 112 can be connected to the outer panel body 311 through the overlapping groove 1121. The longitudinal support 112 is a plate-shaped or columnar structure extending along the Z direction. Its surface near the outer door panel 31 is not completely flat, but has a concave groove structure, which is the overlapping groove 1121. The overlapping groove 1121 extends along the longitudinal direction (Z direction) of the longitudinal support 112, and the overlapping groove 1121 forms a stepped platform on the longitudinal support 112, which facilitates subsequent hooking and positioning with the outer door panel 31. The longitudinal support 112 can fit against the inner side of the outer panel body 311 through the overlapping groove 1121. Specifically, when the longitudinal support 112 passes through the overlap notch 313 and extends into the cavity between the inner and outer panels of the door 3, the outer panel body 311 at the edge of the overlap notch 313 is embedded in the overlap groove 1121 of the longitudinal support 112, so that the longitudinal support 112 and the inner side of the outer panel body 311 form a surface contact fit at this position; this can help to achieve the installation limit of the exterior rearview mirror assembly 1.

[0104] Example 1:

[0105] like Figures 1 to 6 As shown, this invention relates to an exterior rearview mirror assembly 1. The exterior rearview mirror assembly 1 includes three mounting holes 13, which are connected in the Y direction to three fixing holes 33 on the sheet metal of the inner door panel 32 via bolts, ensuring a tight fit between the exterior rearview mirror assembly 1 and the inner door panel 32 and guaranteeing the Y-direction position of the exterior rearview mirror assembly 1. The mounting holes 13 on the bracket 11 are through holes with a diameter of 9mm, and the fasteners that mate with them have a diameter of 6mm and a single-sided clearance of 1.5mm, without restricting the X and Z-direction degrees of freedom of the exterior rearview mirror assembly 1. The lower adhesive layer 17 is fitted and matched with the outer door panel 31. The exterior rearview mirror assembly 1 sinks due to gravity. At the same time, there is a snap-fit ​​mechanism on the rearview mirror base. The snap-fit ​​mechanism hooks the outer door panel 31 from the underside of the outer panel flange 312, controlling the Z-direction relationship between the exterior rearview mirror assembly 1 and the door 3. There is a positioning pin on the base of the exterior rearview mirror assembly 1 that cooperates with the positioning hole 34 provided by the outer door panel 31, controlling the X-direction relationship between the exterior rearview mirror assembly 1 and the outer door panel 31, ensuring the X-direction alignment of the exterior rearview mirror assembly 1 and the outer door panel 31. This positioning method avoids the problem of large fluctuations in the surface difference between the exterior rearview mirror assembly 1 and surrounding parts caused by the relative dimensional fluctuations between the interior door panel 32 and the exterior door panel 31, which are located on the inner door panel 32 in the X and Z directions. At the same time, the exterior rearview mirror assembly 1 is designed with a protruding insert 16, which is directly connected to the exterior door water cutter 2, shortening the dimensional chain between the exterior rearview mirror assembly 1 and the exterior door water cutter 2, and improving the surface difference accuracy between the exterior door water cutter 2 and the exterior rearview mirror assembly 1.

[0106] Specifically, the steps for assembling the exterior rearview mirror assembly 1 and its connection with surrounding components are as follows:

[0107] Step 1: Insert the positioning pin 14 of the exterior rearview mirror assembly 1 into the positioning hole 34 on the outer door panel 31;

[0108] Step 2: Insert the exterior rearview mirror assembly 1 from top to bottom into the gap between the outer door panel 31 and the inner door panel 32. The adhesive mechanism in the exterior rearview mirror assembly 1 is attached to the outer panel flange 312 in the outer door panel 31 and is engaged with the outer panel flange 312 by the snap-fit ​​mechanism.

[0109] Step 3: Connect the bracket 11 in the exterior rearview mirror assembly 1 to the inner door panel 32 using fasteners (bolts);

[0110] Step 4: Insert the protruding insert 16 from the exterior rearview mirror assembly 1 into the insertion groove 21 of the exterior water cutter 2 on the snap-fit ​​surface of the door sheet metal assembly.

[0111] The bonding mechanism and snap-fit ​​mechanism of the exterior rearview mirror assembly 1 of the present invention are directly related to the Z-direction of the door outer panel 31, which can improve the accuracy of the Z-direction matching surface of the front triangular window of the exterior rearview mirror assembly 1 and the Z-direction surface difference of the triangular window assembly; the bottom positioning pin 14 of the exterior rearview mirror assembly 1 is inserted into the positioning hole 34 on the door outer panel 31, which can improve the accuracy of the X-direction matching surface of the front triangular window of the exterior rearview mirror assembly 1 and the X-direction gap surface of the triangular window assembly; the protruding insert 16 of the rear of the exterior rearview mirror assembly 1 directly cooperates with the insertion groove 21 of the door outer water cutter 2, which can improve the cooperation accuracy between the rear of the exterior rearview mirror assembly 1 and the front end of the door outer water cutter 2.

[0112] The exterior rearview mirror assembly 1 disclosed in this invention abandons the traditional two-pin positioning in actual vehicle assembly. When the exterior rearview mirror assembly 1 is installed on the door 3, it is positioned on the outer door panel 31 by overlapping the adhesive layer 17 on the lower side of the rearview mirror in the Z direction. This ensures that the exterior rearview mirror assembly 1 and the door 3 can fit stably in the Z direction, avoiding the problem of large gap between the lower side of the exterior rearview mirror assembly 1 and the outer panel when the exterior rearview mirror assembly 1 is positioned on the inner door panel.

[0113] When the exterior rearview mirror assembly 1 is installed on the door 3, it is positioned on the outer door panel 31 by overlapping the lower adhesive layer 17 of the rearview mirror in the Z direction. The X-direction positioning pin 14 engages with the positioning hole 34 on the outer door panel 31, directly linking the matching state of the exterior rearview mirror assembly 1 with the outer door panel 31. This reduces the dimensional links between the interior door panel 32 and the door and door accessories, making the matching state between the exterior rearview mirror assembly 1 and the door 3 and door accessories more stable. The gap and surface difference tolerance between the exterior rearview mirror assembly 1 and the door accessories is controlled within ±0.5mm. Compared with the traditional two-pin positioning method with the same shape relationship, the tolerance is reduced by 0.4mm. At the same time, the outer water cutter 2 of the door is mutually limited and locked by the rearview mirror insert, which can achieve a surface difference tolerance between the rearview mirror and the outer water cutter of ±0.7mm.

[0114] Obviously, the specific implementation of this invention is not limited to the above-described methods. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
