Description

Technical Field

[0001] The utility model relates to a rearview mirror, in particular to a three-clutch waterproof electric folding rearview mirror. Background Art

[0002] The rearview mirror of a motor vehicle is located on the left and right sides of the head of the motor vehicle. The rearview mirror of a motor vehicle mainly reflects the situation behind the motor vehicle, allowing the driver to indirectly see the situation at these locations. It plays the role of a "second eye" and expands the driver's field of vision.

[0003] Motorcycles are a type of motor vehicle. Existing rearview mirrors in motorcycles are generally of a manually adjustable structure or a separate automatic adjustable structure. The rearview mirror of the separate automatic adjustable structure generally includes a motor, a transmission member and a rotating shaft connected to the lens. When the motor is working, the transmission member drives the rotating shaft to rotate, and the rotating shaft drives the lens to fold or unfold when it rotates. However, since the electric folding rearview mirror has electrical components, it needs to be isolated from water. Especially when washing the motorcycle, it is necessary to pay attention to the flushing position, which makes it inconvenient to use. When sealing the electrical components, subsequent disassembly and maintenance are taken into consideration. Therefore, most of them use two relative shells to connect, and the connecting position is sealed with a sealing gasket. However, the structure sealed with a sealing gasket has a limited service life, and it is necessary to ensure that the sealing gasket installation position is completely fitted during installation, which is inconvenient to install and there is a problem that water cannot be completely isolated.

Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0061] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0062] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0063] See also Figure 1-Figure 8 In an embodiment of the utility model, a three-clutch waterproof electric folding rearview mirror includes: a mounting frame 1, a driving housing 7, a turntable 6, a connecting platform 5, a bracket 3 and a connecting member 4, wherein the connecting member 4 sequentially penetrates a third through slot 304 formed on the bracket 3, a fourth through slot 505 formed on the connecting platform 5, a fifth through slot 606 formed on the turntable 6, a sixth through slot 706 formed on the driving housing 7 and a first through slot 103 formed on the mounting frame 1, and is detachably connected with an elastic member, one end of which is connected to the connecting member 4, and the other end is in contact with the mounting frame 1, so that under the action of an external force, the connecting platform 5 and the bracket 3 can be displaced relative to the mounting frame 1 along the axial direction of the connecting member 4.

[0064] See also Figure 7 , Figure 8 , Fig.12 and Fig.15The three-clutch waterproof electric folding rearview mirror also includes a protective cover 2, and the protective cover 2 is mounted on the outer side of the retaining ring 101 formed on the mounting frame 1 to form a receiving groove, and the drive housing 7 and the turntable 6 are placed in the receiving groove. Further, the protective cover 2 is provided with an annular retaining ring 201, and the annular retaining ring 201 is colinear with the axis of the second through groove 202 formed on the protective cover 2, and an annular embedded groove 504 is formed on the connecting platform 5. When the folding rearview mirror is assembled, the annular retaining ring 201 is placed in the annular embedded groove 504, so that the drive housing 7 and its internal components are all placed in the receiving groove, and at the same time, the opening on the receiving groove (the second through groove 202) is blocked by the connecting platform 5, so that the external water can flow in along the receiving groove. Figure 8 The flow in the flow channel a shown ensures that external water will not enter the containing groove and cause damage to the components in the driving housing 7.

[0065] See also Figure 1 , Fig. 9 , Fig.10 An embedded groove 102 is formed on the mounting frame 1, the first through groove 103 is located at the side end of the embedded groove 102, and the embedded groove 102 and the first through groove 103 are both located on the inner side of the retaining ring 101, and a plurality of blocks 104 are also formed on the mounting frame 1, and the plurality of blocks 104 are evenly arranged in the radial direction of the first through groove 103, and a gap is formed between two adjacent blocks 104. The mounting frame 1 is mainly used for connecting to a locomotive body, that is, the mounting frame 1 is provided with a mounting position for connecting to a locomotive body, preferably, the mounting position is a mounting hole, and during installation, the mounting hole is penetrated by bolts to fix to the locomotive body.

[0066] See also Figure 1 , Fig.10 , Fig.11 and Fig.12The drive housing 7 includes a lower shell 708, and a motor cavity 704 for installing a driving member is formed on one side of the lower shell 708. The motor cavity 704 is a box structure, and its shape is the same as the cavity shape of the embedded groove 102, so that when installing, the motor cavity 704 can be completely placed in the embedded groove 102, and the motor cavity 704 is blocked by a blocking plate 709 detachably connected to the lower shell 708, so as to protect the driving member placed in the motor cavity 704. A sixth through slot 706 is formed on one side, and a mounting slot 701 for placing the turntable 6 is formed at one end of the sixth through slot 706, and a plurality of clamping slots 705 are formed at the other end. The clamping slot 705 is clamped with the clamping block 104, so that after the drive housing 7 is placed on the mounting frame 1, the embedded slot 102 limits the motor cavity 704, and the clamping block 104 is clamped with the clamping slot 705, so as to limit the side of the drive housing 7 away from the motor cavity 704, so as to improve the stability of the drive housing 7 after being placed on the mounting frame 1.

[0067] It should also be noted that since the driving member serves as a driving mechanism and is mainly used to drive the rotation of the turntable 6, a through groove is formed between the motor cavity 704 and the mounting groove 701. The through groove is used for the driving member to partially extend into the mounting groove 701 to achieve connection with the turntable 6, thereby driving the turntable 6 to rotate when the driving member is working to achieve the driving requirement.

[0068] Exemplary, in a specific implementation, the driving member includes a motor installed in the motor cavity 704, the output shaft of the motor is connected to a worm through a transmission member, the worm is meshed with a worm wheel installed on the turntable 6, and the transmission member can be two mutually meshing bevel gears, and the two bevel gears are respectively fixed to the output shaft and the worm of the motor. Of course, other transmission structures can also be used, which can be selected according to specific needs, and this embodiment does not make specific limitations on this.

[0069] See also Figure 1 , Fig.13 and Fig.15At least three limiting grooves 607 are formed on the side of the turntable 6 facing the connecting platform 5, which are used to engage with the fourth limiting protrusion 503 formed on the connecting platform 5, and the limiting grooves 607 and the two ends of the fourth limiting protrusion 503 along the tangential direction thereof are both inclined; a driving connecting portion 604 is formed on the side of the turntable 6 facing the driving housing 7, and the driving connecting portion 604 is placed in the mounting groove 701. The worm gear is formed on the driving connecting portion 604 and meshes with the worm. Through the self-locking effect of the worm gear and the worm, the position of the turntable 6 is locked when the motor does not move, thereby cooperating with the fourth limiting protrusion 503 and the limiting grooves 607 to limit the connecting platform 5, forming a first clutch structure. Of course, when the connecting platform 5 is subjected to external force, the radial position relative to the turntable 6 can be changed.

[0070] See also Figure 1 , Fig.12 and Fig.13 , at least three embedded positions 601 are formed on the side of the turntable 6 facing the driving shell 7, and arc-shaped limiting portions 602 and inclined guide portions 603 are respectively formed at both ends of the embedded positions 601 along the arc direction; the elastic limiting column 707 installed on the lower shell 708 protrudes from the lower shell 708 and is placed in one of the embedded positions 601. Preferably, the elastic limiting column 707 includes a cylindrical rod, one end of which protrudes from the driving shell 7, and the other end is inserted into a cylindrical groove formed on the driving shell 7, and is connected to a cylindrical spring placed in the cylindrical groove. Of course, in order to prevent the cylindrical rod from completely detaching from the cylindrical groove, a limiting structure can be set on the cylindrical rod located in the cylindrical groove, and the limiting structure includes but is not limited to an annular protrusion.

[0071] In this embodiment, when the arc-shaped limiting portion 602 is in contact with the elastic limiting column 707, a limiting force is generated on the turntable 6 as a whole, so that when the connecting platform 5 rotates relative to the turntable 6, the position of the turntable 6 is fixed. At the same time, the inclined guide portion 603 is able to generate an extrusion force on the elastic limiting column 707 when the turntable 6 rotates, so that the elastic limiting column 707 can enter another embedded position 601 on the turntable 6, thereby increasing the rotation angle of the turntable 6. The above-mentioned structure is mainly set to achieve that after the connecting platform 5 is bent to a certain position, the reset angle of the turntable 6 is increased to achieve the overall reset of the connecting platform 5 and the end of the connecting platform 5 away from the turntable 6, that is, the folded position can be finally reached.

[0072] See also Figure 1 , Fig.12 and Fig.13The drive connection part 604 is arranged in an annular structure, and a plurality of limiting parts 605 are evenly arranged on the inner side of the drive connection part 604 along its radial direction. The plurality of limiting parts 605 are used to clamp the worm gear of the driving member. The worm gear is arranged in an annular structure. When the turntable 6 is installed, the worm gear is installed synchronously. A plurality of arc-shaped protrusion blocks 702 are formed at one end of the sixth through groove 706. The plurality of arc-shaped protrusion blocks 702 are evenly arranged along the radial direction of the sixth through groove 706. The worm gear and the drive connection part 604 are sleeved on the outer sides of the plurality of arc-shaped protrusion blocks 702. Preferably, an inclined part 703 is also formed at the end of the arc-shaped protrusion block 702 to reduce the thickness of the end of the arc-shaped protrusion block 702 and facilitate the overall installation of the worm gear and the drive connection part 604.

[0073] See also Fig.13 , Fig.14 , Fig.15 and Fig.16 , an extension sleeve 502 is provided on the side of the connecting platform 5 facing the fourth limiting protrusion 503, and the extension sleeve 502 sequentially passes through the fifth through slot 606 formed on the turntable 6, the sixth through slot 706 formed on the lower shell 708 and the first through slot 103 formed on the mounting frame 1, and the axis of the extension sleeve 502 and the fourth through slot 505 formed on the connecting platform 5 are colinear, and are used for inserting and placing the connecting member 4; at least three third limiting protrusions 501 are provided on the side of the connecting platform 5 away from the extension sleeve 502, and a second limiting groove is formed between two adjacent third limiting protrusions 501, and a first limiting protrusion 303 that is engaged with the second limiting groove is formed on the bracket 3 located at one end of the third through slot 304 to form a second clutch structure, and the first limiting protrusion 303 and the two ends of the third limiting protrusion 501 along the tangential direction are arranged in an inclined shape, so that when the bracket 3 is subjected to external force, the radial position of the bracket 3 relative to the connecting platform 5 can be changed; a circular groove 301 is formed on the bracket 3 located at the other end of the third through groove 304, and the circular groove 301 is colinear with the axis of the third through groove 304, and the diameter of the circular groove 301 is larger than the diameter of the third through groove 304, so as to form an annular platform at the overlapping position of the circular groove 301 and the end of the third through groove 304, and a plurality of first limiting grooves 302 that are clamped with the second limiting protrusion 402 on the upper side of the connecting member 4 are formed on the annular platform to form a third clutch structure, and the second limiting protrusion 402 and the first limiting groove 302 are arranged in an inclined shape at both ends along the tangential direction.

[0074] It should be noted that the axial length of the extension sleeve 502 on the connecting platform 5 is greater than the axial length of the turntable 6, so that when the connecting platform 5 is installed on the turntable 6, the extension sleeve 502 passes through the turntable 6 as a whole, so that the gap between the connecting member 4 and the extension sleeve 502 forms a drainage channel b, so that the water entering from the upper end of the connecting member 4 will not contact the outside of the turntable 6, thereby avoiding the contact between the external water and the components in the motor cavity 704, and achieving an effective drainage effect.

[0075] See also Fig. 9 , Fig.17 and Fig.18 The connecting member 4 includes an integrally formed extension disk 401, a first cylindrical rod 405 and a second cylindrical rod 406, the diameters of the extension disk 401, the first cylindrical rod 405 and the second cylindrical rod 406 are successively reduced; a plurality of second limiting protrusions 402 that are snap-fitted with the first limiting groove 302 are evenly arranged on one side of the extension disk 401 facing the first cylindrical rod 405 along the radial direction of the extension disk 401; a limiting portion 403 is formed at the connection between the first cylindrical rod 405 and the second cylindrical rod 406, and the limiting portion 403 is arranged in an arc-shaped structure, and a limiting ring 8 is sleeved on the second cylindrical rod 406, and the limiting ring 8 is snap-fitted on The bracket 3 is formed in the card slot 105, and the inner side of the limit ring 8 is formed with an arc-shaped protrusion 801, the arc-shaped protrusion 801 has the same diameter as the limit portion 403 arranged in an arc-shaped structure, and a transition gap for providing a rotation stroke is formed between the two ends or one end of the arc-shaped protrusion 801 and the limit portion 403. Since the position of the limit ring 8 relative to the mounting frame 1 is fixed, the function of the limit ring 8 is to limit the angular stroke of electric folding and unfolding, thereby determining the stop position under electric drive. If the angle exceeds the limit stroke, it is necessary to unload the force through the clutch structure without damaging the overall structure, and restore to a normal state within an electric drive start and close cycle.

[0076] It should be noted that a clamping portion 802 is formed on one side of the limit ring 8, and the clamping portion 802 is planar, so that when the limit ring 8 is clamped into the clamping groove 105, it can ensure that the limit ring 8 will not rotate radially. Of course, the shape of the clamping groove 105 is set to match the shape of the limit ring 8.

[0077] Preferably, the extension plate 401 , the first cylindrical rod 405 and the second cylindrical rod 406 are all hollow structures with both ends being conductive, so that water on the connector 4 can flow downward along its inner side to avoid contact with components in the motor cavity 704 .

[0078] See also Figure 1 and Figure 2The elastic member includes a spring 9, a connecting ring 10 and a U-shaped connecting piece 11. The spring 9 and the connecting ring 10 are sleeved on the second cylindrical rod 406, and the U-shaped connecting piece 11 is clamped in the annular groove 404 formed on the second cylindrical rod 406; one end of the spring 9 abuts against the inner wall of the clamping groove 105, and the other end abuts against the connecting ring 10, and generates abutting force on the connecting ring 10, so that the connecting ring 10 abuts against the U-shaped connecting piece 11. The U-shaped connecting piece 11 is self-tightened in the annular groove 404 by the abutting force of the spring 9, and is self-tightened in the connecting ring 10 with the annular groove 404, so that the entire structure forms a whole.

[0079] The utility model can effectively improve the rotation angle of the folding rearview mirror by setting three mechanical clutch structures. At the same time, if an external force impact or reversing occurs, the mechanical clutch structure will be dislocated first, the overall structure will not be damaged, and the driving parts will not be damaged.

[0080] The annular retaining ring 201 is placed in the annular embedded groove 504, so that the drive housing 7 and its internal components are all placed in the receiving groove, and the opening of the receiving groove (the second through groove 202) is blocked by the connecting platform 5, so that the external water can flow in along the Figure 8 The flow in the flow channel a shown in the figure flows. When the connecting platform 5 is installed on the turntable 6, the extension sleeve 502 passes through the turntable 6 as a whole, so that the gap between the connecting member 4 and the extension sleeve 502 forms a drainage flow channel b, so that the water entering from the upper end of the connecting member 4 will not contact the outer side of the turntable 6, thereby avoiding the contact between the external water and the components in the motor cavity 704, and achieving an effective drainage effect.
