Description

Technical Field

[0001] This utility model relates to the field of rearview mirror structure technology, and in particular to a structure for an electric steering adjuster for a car rearview mirror. Background Technology

[0002] In the automotive manufacturing industry, rearview mirrors are a key component related to driving safety, and the ease of installation and removal of their lenses has always been a major concern. Currently, most traditional rearview mirrors on the market use plastic clips to connect the lens to the internal electric adjuster. This clip-on connection structure has significant drawbacks in practical applications. When it is necessary to replace or repair the lens, the operation is extremely cumbersome and risky. Repair personnel usually need to press the entire lens to a maximum tilt angle to barely create a gap between the edge of the lens and the rearview mirror housing. Then, they carefully probe into the gap with a special pry bar or flathead screwdriver and try to release the fragile and hidden plastic clips by feel. This process not only requires high skill from the operator, but is also very easy to break due to improper force or misjudgment of position, or directly cause scratches, cracks or even shattering of the entire lens. Utility Model Content

[0003] This invention provides a structure for an electric steering adjuster for a car rearview mirror, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An electric steering adjuster structure for a car rearview mirror includes several quick-release structures mounted on the mirror and an adjuster body for fixing the mirror. The adjuster body has several insertion holes that cooperate with each of the quick-release structures. The quick-assembly structure includes a fixed plate and a movable plate.

The straight groove is parallel to the moving direction of the slide block. One end of the V-shaped groove is connected to the end of the straight groove away from the axis of the fixed plate. One end of the inclined groove is connected to the other end of the V-shaped groove, and the other end of the inclined groove is connected to the middle of the straight groove. The inclined groove has the same depth as the straight groove at the end furthest from the straight groove, and the depth of the inclined groove gradually decreases along the direction closer to the straight groove.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0018] like Figures 1 to 7 As shown, this application provides an electric steering adjuster structure for a car rearview mirror, including a plurality of quick-release structures 200 mounted on a lens 100 and an adjuster body 300 for fixing the lens 100. The adjuster body 300 is provided with a plurality of insertion holes 301 that cooperate with each quick-release structure 200. The quick-installation structure 200 includes a fixed plate 201 and a movable plate 202. The fixed plate 201 is provided with a number of guide rails 203, which intersect at the axis of the fixed plate 201. The length direction of the guide rails 203 is along the radial direction of the fixed plate 201. Each guide rail 203 is slidably provided with a slide block 205. The slide block 205 has a slope surface that is coplanar with the fixed plate 201. The outer wall of the movable plate 202 is provided with a groove that cooperates with the slope surface. Several support arms 204 are slidably arranged on the movable disk 202, and the support arms 204 move in the radial direction of the movable disk 202. An insert plate 206 is provided on the slide block 205, and the insert plate 206 is slidably connected to the support arms 204 along the axis of the fixed disk 201. The fixed plate 201 is provided with several locking structures for locking each slide 205.

[0019] Specifically, the adjuster body 300 is installed inside the rearview mirror housing, and the lens 100 is fixed to the adjuster body 300 through several quick-release structures 200, thereby realizing the installation of the lens 100. The number and arrangement of the quick-release structures 200 can be adjusted arbitrarily according to the actual situation, which will not be elaborated here. The fixed plate 201 and the movable plate 202 on the quick-release structure 200 are coaxially arranged. Since the movable plate 202 is connected to the slide 205 through a slope and a groove, when the movable plate 202 moves along the axis of the fixed plate 201, the movable plate 202 can push the slide 205 to move on the guide rail 203, thereby controlling the position of the slide 205 in the radial direction of the fixed plate 201, that is, adjusting the distance between the slides 205. The slide 205 is connected to the support arm 204 through the insert plate 206, thereby controlling the support arms 204 to move closer or further apart.

[0020] During assembly, several quick-release structures 200 are aligned with several insertion holes 301 on the regulator body 300. At this time, several support arms 204 on the quick-release structures 200 are in a retracted state, which increases the alignment accuracy requirement and reduces the assembly difficulty. After the support arms 204 on the quick-release structures 200 are inserted into the insertion holes 301, the end face of the movable disk 202 contacts the end face of the regulator body 300. At this time, the movable disk 202 and the regulator body 300 are relatively stationary, while the continued movement of the lens 100 will push the fixed disk 201 and the movable disk 202 to move relative to each other. The movable disc 202 pushes several slides 205 to separate from each other, thereby using several insert plates 206 to drive several support arms 204 to separate from each other. The support arms 204 abut against the inner wall of the insertion hole 301, thereby realizing the external support and fastening work between the support arms 204 and the insertion hole 301. The locking structure can fix the position of the slides 205 on the guide rail 203, so that the quick-release structure 200 and the regulator body 300 are kept connected. Since the movable disc 202 and the fixed disc 201 move relative to each other, the insert plates 206 and the support arms 204 can slide relative to each other.

[0021] In actual use, the adjuster body 300 can be fastened to the rearview mirror housing with several bolts, and as... Figure 2 As shown, the bolt can pass through the socket 301 and be installed in the fixing hole on the adjuster body 300 located behind the socket 301. Therefore, the setting position of the socket 301 needs to refer to the fixing position between the adjuster body 300 and the rearview mirror housing. Furthermore, the quick-install structure 200 can achieve the connection between the lens 100 and the adjuster body 300 by means of the socket 301. Therefore, the socket 301 can be fully utilized, simplifying the structural method.

[0022] The technical solution of this utility model effectively solves the problem of difficult assembly and disassembly of the lens 100 and the regulator body 300. It enables the lens 100 and the regulator body 300 to be quickly assembled and disassembled by the quick-assembly structure 200 and the regulator body 300 through the mutual approach or separation of several support arms 204 in the quick-assembly structure 200. This effectively simplifies the operation, reduces the technical requirements for workers, and effectively avoids damage to plastic parts or scratches to the lens 100, thereby improving the safety of operation.

[0023] Furthermore, such as Figure 2 and Figure 6 As shown, each support arm 204 has horizontal grooves 207 on its outer wall, and each insertion hole 301 has grooves 302 on its inner wall that cooperate with the horizontal grooves 207.

[0024] By utilizing the interlocking fit between the horizontal ribs 207 and the grooves 302, the fit between the support arm 204 and the inner wall of the insertion hole 301 can be improved, preventing relative sliding and affecting the assembly firmness of the lens 100. Since the sliding direction of the support arm 204 on the movable disk 202 is along the radial direction of the movable disk 202, the support arm 204 will move horizontally towards the inner wall of the insertion hole 301. At this time, the horizontal ribs 207 and the corresponding grooves 302 can be directly inserted and locked on the same horizontal plane without relative displacement in the axial direction of the insertion hole 301. This allows the cross-sectional shape of the horizontal ribs 207 and the cross-sectional shape of the grooves 302 to be arc-shaped rather than trapezoidal, which can improve the connection firmness between the quick-installation structure 200 and the insertion hole 301 in the axial direction of the insertion hole 301.

[0025] Furthermore, such as Figure 2 and Figure 6 As shown, a retaining ring 208 is coaxially arranged on the end face of the movable disk 202, and a ring groove 303 that cooperates with the retaining ring 208 is opened on the end face of each insertion hole 301.

[0026] When several support arms 204 on the quick-release structure 200 are inserted into the socket 301, the insertion ring 208 will be inserted into the ring groove 303 simultaneously. At this time, on the surface of the movable disc 202, the insertion ring 208 and the ring groove 303 can lock each other, thereby achieving the locking function of the quick-release structure 200 on the surface of the movable disc 202. In addition, the cross groove 207 and the groove 302 lock the quick-release structure 200 in the axial direction of the socket 301, thereby improving the connection firmness between the quick-release structure 200 and the regulator body 300.

[0027] Furthermore, to facilitate the interlocking connection between the insertion ring 208 and the ring groove 303, the opening shape of the ring groove 303 can be set to a conical shape. This utilizes the guiding effect of the conical shape to allow the end of the insertion ring 208 to slide smoothly into the ring groove 303, thereby improving ease of use.

[0028] Furthermore, such as Figure 4 As shown, each slide 205 is provided with two sets of locking structures, and the two sets of locking structures are respectively set on both sides along the direction perpendicular to the movement of the slide 205; when the slide 205 moves on the guide rail 203, the locking structures on both sides can provide a uniform force to the slide 205, thereby improving the structural stability.

[0029] Furthermore, such as Figures 8 to 9 As shown, the carding structure includes a guide groove formed on the fixed plate 201 and a sliding post 212 that slides in the guide groove. The sliding post 212 is connected to the corresponding slide block 205. The guide groove includes a straight groove 209, a V-shaped groove 210, and an inclined groove 211. The straight groove 209 is parallel to the moving direction of the slide block 205. One end of the V-shaped groove 210 is connected to the end of the straight groove 209 away from the axis of the fixed plate 201. One end of the inclined groove 211 is connected to the other end of the V-shaped groove 210, and the other end of the inclined groove 211 is connected to the middle of the straight groove 209. The groove depth of the inclined groove 211 at the end away from the straight groove 209 is equal to the groove depth of the straight groove 209, and the groove depth of the inclined groove 211 gradually decreases along the direction close to the straight groove 209.

[0030] Specifically, when the quick-release structure 200 is assembled with the socket 301, the movable plate 202 moves relative to the fixed plate 201 and pushes the slide block 205 to slide on the guide rail 203. At this time, the slide block 205 will drive the slide column 212 to slide synchronously in the straight groove 209. When the slide column 212 slides to the end of the straight groove 209, the slide column 212 slides into the V-shaped groove 210 and stops at the tip of the V-shaped groove 210. This position of the V-shaped groove 210 can prevent the slide column 212 from moving towards the axis of the fixed plate 201, that is, prevent the slide block 205 from moving in the opposite direction, so that the several support arms 204 and the socket 301 are kept in a tight connection. When it is necessary to remove the lens 100, the slide column 212 continues to slide in the V-shaped groove 210. When the slide column 212 slides into the inclined groove 211, the slide block 205 can move on the guide rail 203 toward the axis of the fixed plate 201. At this time, the slide column 212 will slide back into the straight groove 209 using the inclined groove 211, thereby unlocking the lens 100 and the adjuster body 300. It should be noted that when the slide block 205 moves away from the axis of the fixed plate 201, the slide column 212 slides in the straight groove 209. In order to prevent the slide column 212 from sliding directly into the inclined groove 211, the depth of the inclined groove 211 can be gradually changed. That is, a step will be generated at the connection position between the end of the inclined groove 211 and the straight groove 209 to prevent the slide column 212 from entering the inclined groove 211, thereby ensuring that the slide column 212 moves in one direction in the guide groove.

[0031] Furthermore, such as Figure 9 As shown, a connecting sleeve 213 is fitted on the sliding column 212, and a guide post 214 is provided on the outer wall of the connecting sleeve 213. The guide post 214 is slidably inserted into the slide block 205. The connecting sleeve 213 and the slide block 205 are connected by an elastic body 215, and the connecting sleeve 213 and the sliding column 212 are connected by a spring 216.

[0032] Because the depths of the guide grooves are not uniform, the sliding column 212 needs to be able to slide on the connecting sleeve 213. The spring 216 provides an elastic force to the sliding column 212, ensuring that the end of the sliding column 212 is always in contact with the bottom of the guide groove. Since the sliding column 212 can slide in the V-groove 210 and the inclined groove 211, the distance between the sliding column 212 and the slide block 205 will change. At this time, the guide column 214 can slide on the slide block 205, and the elastic body 215 provides a restoring force for the sliding column 212 and the connecting sleeve 213. Specifically, when the sliding column 212 moves from the straight groove 209 to the V-groove 210, the elastic force provided by the elastic body 215 will allow it to move smoothly in the V-groove 210.

[0033] Furthermore, such as Figure 7 As shown, a spring 217 is connected between the fixed disk 201 and the movable disk 202. A rod 218 is provided in the middle of the spring 217. One end of the rod 218 is fixedly connected to the fixed disk 201, and the other end of the rod 218 passes through the movable disk 202 and slides relative to it.

[0034] Spring 217 provides elastic thrust to movable plate 202, allowing several slides 205 to approach each other in their natural state. When slide column 212 moves to the tip of V-groove 210, spring 217 can lock slide column 212 in that position of V-groove 210, thereby stabilizing the structure. Insert rod 218 provides support for spring 217 and prevents it from bending.

[0035] In actual use, installing the lens 100 simply requires pressing it onto the adjuster body 300. Removing it is as simple as pressing the lens 100 again to remove it from the adjuster body 300. While this method is convenient, it also makes the lens 100 susceptible to theft. Therefore, to improve security, a commonly used electronic lock structure can be installed inside the rearview mirror housing. When the car is powered off, the electronic lock locks the lens 100; when removing the lens 100, powering on the car unlocks the electronic lock. Since this type of electronic lock is quite common, it will not be elaborated upon here.

Accordingly, this specification and drawings are merely exemplary illustrations of the application as defined herein, and are to be considered as covering any and all modifications, variations, combinations, or equivalents within the scope of this application.
