Description

Technical Field

[0001] The present application belongs to the technical field of rearview mirrors, and in particular relates to a folding and resetting structure of a rearview mirror. Background Art

[0002] In existing technology, due to the high mounting height of commercial vehicle electronic rearview mirrors, if they are struck by foreign objects while driving, the traditional automatic and electric folding functions cannot automatically restore the mirror's camera to its original position after the impact.

The following describes the implementation of the present invention based on its overall structure.

[0044] Reference Figure 1 As shown, the embodiment of the present application provides a rearview mirror folding and resetting structure, comprising:

[0045] Rotating seat 2;

[0046] A fixed seat 1 is provided in the middle of the rotating seat 2. A mounting shaft 11 is installed in the middle of the fixed seat 1 for connecting with the rearview mirror. A stopper 12 extends circumferentially from the outer edge of the fixed seat 1.

[0047] A first support portion 13 and a second support portion 14 are circumferentially distributed on the side wall of the fixed base 1 facing the rotating base 2. The outer diameter of the first support portion 13 is larger than the inner diameter of the second support portion 14.

[0048] A third support portion 21 and a fourth support portion 22 are circumferentially distributed on the side wall of the rotating seat 2 facing the fixed seat 1. The outer diameter of the third support portion 21 is larger than the outer diameter of the fourth support portion 22.

[0049] The outer diameter of the first support portion 13 is equal to the outer diameter of the third support portion 21 , and the outer diameter of the second support portion 14 is equal to the outer diameter of the fourth support portion 22 ;

[0050] The first elastic member 3 abuts between the stopper 12 and the first support portion 13. The first elastic member 3 also abuts against the third support portion 21 to limit the rotation of the rotating base 2 in the first direction.

[0051] The second elastic member 4 abuts against the fourth support portion 22 and the mounting shaft 11 , and the second elastic member 4 also abuts against the second support portion 14 , for limiting the rotation of the rotating base 2 along the second direction.

[0052] according to Figure 1 Those skilled in the art can set a rotating seat 2 to cooperate with the fixed seat 1, wherein the rotating seat 2 is connected to the rearview mirror to achieve rotational reset of the rearview mirror.

[0053] Specifically, a mounting shaft 11 is provided in the middle of the fixing seat 1 , the rotating seat sleeve is provided on the outer wall of the mounting shaft 11 , and the mounting shaft 11 is rotatably connected to the rearview mirror, thereby limiting the rotation of the rearview mirror.

[0054] During the process of setting the fixing seat 1 , those skilled in the art may set a stopper 12 at the outer edge of the fixing seat 1 , wherein the stopper 12 extends circumferentially along the fixing seat 1 toward the outer edge of the side wall of the rotating seat 2 .

[0055] With the above structure, those skilled in the art can arrange the blocking portion to support the rotating base 2 , so that the fixed base 1 and the rotating base 2 can be stably sleeved and rotated relative to each other.

[0056] Furthermore, a first support portion 13 and a second support portion 14 are circumferentially distributed on the side wall of the fixed seat 1 facing the rotating seat 2, and the outer diameter of the first support portion 13 is larger than the inner diameter of the second support portion 14; a third support portion 21 and a fourth support portion 22 are circumferentially distributed on the side wall of the rotating seat 2 facing the fixed seat 1, and the outer diameter of the third support portion 21 is larger than the outer diameter of the fourth support portion 22.

[0057] With the above structure, those skilled in the art can set the first support portion 13 and the third support portion 21 to have the same outer diameter, and the second support portion 14 and the fourth support portion 22 to have the same outer diameter.

[0058] According to the above arrangement, the first support portion 13 is disposed on the fixed base 1 and extends toward the third support portion 21; the third support portion 21 is disposed on the rotating base 2 and extends toward the first support portion 13. According to the above structure, the first support portion 13 and the third support portion 21 have the same outer diameter, and the first support portion 13 extends toward the side wall of the third support portion 21 and contacts the third support portion 21.

[0059] Furthermore, those skilled in the art have also configured the second support portion 14 and the fourth support portion 22 to have equal outer diameters. That is, the second support portion 14 is disposed on the fixed base 1 and extends toward the fourth support portion 22; the fourth support portion 22 is disposed on the rotating base 2 and extends toward the second support portion 14. The second support portion 14 and the fourth support portion 22 have equal outer diameters, and the second support portion 14 extends toward and contacts the sidewall of the fourth support portion 22.

[0060] According to the above structure, technicians in this field set the blocking part 12, the structure in which the first support part 13 conflicts with the third support part 21, and the structure in which the second support part 14 conflicts with the fourth support part 22, so as to form a structure in which the rotating seat 2 is sleeved on the outer wall of the mounting shaft 11 on the fixed seat 1 and rotates.

[0061] Furthermore, in order to limit the rotation and resetting of the rotating base 2 relative to the fixed base 1 , those skilled in the art may further provide a first elastic member 4 and a second elastic member 5 .

[0062] Specifically, the first elastic member 3 abuts between the blocking portion 12 and the first support portion 13. At the same time, the first elastic member 3 also abuts against the third support portion 21 to limit the rotation of the rotating seat 2 along the first direction; the second elastic member 4 abuts against the fourth support portion 22 and the mounting shaft 11. The second elastic member 4 also abuts against the second support portion 14 to limit the rotation of the rotating seat 2 along the second direction.

[0063] According to the structure of this embodiment, the first elastic member 3 abuts between the blocking portion 12 and the first supporting portion 13 , and the first supporting portion 13 and the third supporting portion 21 abut against each other, so the first elastic member 3 also abuts against the third supporting portion 21 .

[0064] Due to the connection structure of the first elastic member 3, when the rotating base 2 rotates relative to the fixed base 1 in the first direction, the third support portion 21 rotates along with the rotating base 2. The rotation of the third support portion 21 can squeeze and deform the first elastic member 3. After the force on the rotating base 2 disappears, the first elastic member 3 resets, thereby driving the rotating base 2 to reset.

[0065] Due to the connection structure of the second elastic member 4, when the rotating base 2 rotates relative to the fixed base 1 in the second direction, the fourth support portion 22 rotates along with the rotating base 2. The rotation of the fourth support portion 22 can squeeze the second elastic member 5 and deform it. After the force on the rotating base 2 disappears, the second elastic member 4 resets, thereby driving the rotating base 2 to reset.

[0066] It is understandable that those skilled in the art may set the first direction and the second direction as opposite rotation directions, so that the rotating base 2 can be rotated and reset in two opposite directions.

[0067] In the above structure, when the first elastic member 3 is in an undeformed state, both ends of the first elastic member 3 abut against the stopper 12 and the first support portion 13, respectively, thereby determining the installation position of the first elastic member 3. The position where the first elastic member 3 abuts against the first support portion 13 also abuts against the third support portion 21. In other words, when the third support portion 21 rotates and compresses the first elastic member 3, the first elastic member 3 separates from the first support portion 13.

[0068] Similar to the first elastic member 3, the two ends of the second elastic member 4 abut against the second support portion 14 and the mounting shaft 11, respectively, thereby determining the installation position of the second elastic member 3. When the rotating base 2 rotates, the fourth support portion 22 squeezes the second elastic member 3 and deforms it, thereby separating the second elastic member 3 from the second support portion 14.

[0069] In an optional embodiment, preferably, the edge of the rotating seat 2 extends toward the direction of the fixed seat 1 to form a first limit block 23, and the edge of the blocking portion 12 extends toward the edge of the fixed seat 1 to form a second limit block 15, and the first limit block 23 and the second limit block 15 are separated from or conflict with each other.

[0070] With the above structure, those skilled in the art can configure the rotating base 2 and the fixed base 1 to have a first stopper 23 and a second stopper 15, respectively. Specifically, the first stopper 23 can be located at the edge of the rotating base 2, and the second stopper 15 can be located at the edge of the stopper 12. The first stopper 23 extends toward the fixed base 1, and the second stopper 15 extends toward the edge of the fixed base 1.

[0071] The second limiting block 15 is arranged on the stop portion 12, that is, the second limiting block 15 maintains the stability of the relative position. When the rotating base 2 rotates, the first limiting block 23 can follow and rotate, thereby can conflict with or separate from the second limiting block 15.

[0072] It can be understood that, in the above structure and process, the rotation angle of the rotating base 1 can be limited by the interference and separation of the relative positions of the first limiting block 15 and the second limiting block 23 .

[0073] Furthermore, those skilled in the art can set the first support part 13, the second support part 14, the third support part 21 and the fourth support part 22. Preferably, the first support part 13 and the third support part 21 are both provided with a first opening, and the first openings are set correspondingly. In the above structure, those skilled in the art set the first support part 13 and the third support part 21 to have the same outer diameter, and the first support part 13 extends toward the rotating seat 2, and the third support part 21 extends toward the fixed seat 1. That is, in the process of extending the first support part 13 and the third support part 21, the first support part 13 and the third support part 21 extend to conflict.

[0074] In this embodiment, the first support portion 13 and the third support portion 21 are both provided with a first opening, and the first openings are located at the same position on the first support portion 13 and the third support portion 21. In other words, the first support portion 13 and the third support portion 21 maintain the same shape and the first support portion 13 and the third support portion 21 are in contact with each other.

[0075] Regarding the configuration of the second support portion 14 and the fourth support portion 22, both are provided with second openings, and the second openings are arranged in correspondence with each other. Similar to the above-described configuration, a person skilled in the art would configure the second support portion 14 and the fourth support portion 22 to have the same outer diameter, with the second support portion 14 extending toward the rotating base 2 and the fourth support portion 22 extending toward the fixed base 1. In other words, during the extension process, the second support portion 14 and the fourth support portion 22 extend until they collide with each other.

[0076] Regarding the arrangement of the second support portion 14 and the fourth support portion 22, a second opening is provided on each of the second support portion 14 and the fourth support portion 22, and the second opening on the second support portion 14 corresponds to the second opening on the fourth support portion 22. In other words, the second support portion 14 and the fourth support portion 22 have the same shape and the same opening position.

[0077] It is worth noting that in the above structure, the first support portion 13 and the third support portion 21 are in conflict with each other and can move relative to each other; the second support portion 14 and the fourth support portion 22 are in conflict with each other and can move relative to each other.

[0078] In the above structure, those skilled in the art arrange that the first elastic member 3 abuts against the stopper 12 and the first support portion 13, and the end of the first elastic member 3 abutting against the first support portion 13 also abuts against the third support portion 21. In this embodiment, preferably, the stopper 12 has a first abutting portion 121, and second abutting portions 131 are provided at the two first openings, and the two ends of the first elastic member 3 abut against the first abutting portion 121 and the second abutting portion 131, respectively.

[0079] According to the above structure, specifically, the portions of the first elastic member 3 that abut the stopper 12, and the first support portion 13 and the third support portion 21 abut against the first abutting portion 121 and the second abutting portion 131, respectively. The stopper 12 is provided with the first abutting portion 121, with one end of the first elastic member 3 abutting against the first abutting portion 121. A second abutting portion 131 is provided at the first opening between the first support portion 13 and the third support portion 21. That is, the first support portion 13 is provided with the second abutting portion 131, and the third support portion 21 is also provided with the second abutting portion 131. The other end of the first elastic member 3 abuts against the second abutting portion 131 between the first support portion 13 and the third support portion 21.

[0080] Due to the above structure, when the rotating base 2 is in a non-rotating state, the two ends of the first elastic member 3 respectively maintain contact with the first abutment portion 121 and the second abutment portion 131. When the rotating base 2 begins to rotate in the first direction and during the rotating state, the end of the first elastic member 3 abutting the first abutment portion 121 remains stationary; the other end of the first elastic member 3 separates from the second abutment portion 131 on the first support portion 13. At the same time, the other end of the first elastic member 3 is pressed against the second abutment portion 131 on the third support portion 21, thereby causing the first elastic member 3 to be squeezed and deformed. After the force causing the rotating base 2 to rotate disappears, the first elastic member 3 recovers its deformation, thereby allowing the rotating base 2 to return to its original position.

[0081] In this embodiment, the two second openings have third abutment portions 141, the mounting shaft 11 has a fourth abutment portion 111, and both ends of the second elastic member 4 abut against the third abutment portions 141 and the fourth abutment portion 111, respectively. In the above structure, the second support portion 14 and the fourth support portion 22 both have second openings, are provided with third abutment portions 141 at the second openings, and the mounting shaft 11 is provided with a fourth abutment portion 111.

[0082] Due to the above structure, when the rotating base 2 is in a non-rotating state, the two ends of the second elastic member 4 respectively abut against the third abutting portion 141 and the fourth abutting portion 111. When the rotating base 2 begins to rotate in the second direction and during the rotating state, the end of the second elastic member 4 abutting against the fourth abutting portion 111 remains stationary; the other end of the second elastic member 4 separates from the third abutting portion 141 on the second support portion 14. At the same time, the other end of the second elastic member 4 is pressed against the third abutting portion 141 on the fourth support portion 22, thereby causing the second elastic member 4 to be squeezed and deformed. After the force causing the rotating base 2 to rotate disappears, the second elastic member 4 recovers its deformation, thereby allowing the rotating base 2 to return to its original position.

[0083] In the above arrangement, those skilled in the art can arrange the first and second openings in relative orientation. That is, when the rotating base 2 rotates in the first direction, the second elastic member 4 remains stationary; when the rotating base 2 rotates in the second direction, the first elastic member 3 remains stationary. Furthermore, in an alternative embodiment, those skilled in the art can arrange the first direction to be clockwise and the second direction to be counterclockwise, thereby enabling the rotating base 2 to rotate and reset in both directions, thereby driving the rearview mirror to rotate and reset in both clockwise and counterclockwise directions.

[0084] In an optional embodiment, preferably, both ends of the first elastic member 3 and the second elastic member 4 are provided with a bent portion for connecting with the first abutting portion 121, the second abutting portion 131, the third abutting portion 141, and the fourth abutting portion 111. By providing the bent portion, the abutting structure at both ends of the first elastic member 3 and the second elastic member 4 can be made more stable.

[0085] More preferably, the first elastic member 3 and the second elastic member 4 are both spiral springs. In this embodiment, those skilled in the art will use spiral springs to make the first elastic member 3 and the second elastic member 4, so as to stably complete the restriction and reset of the rotation process of the rotating base 2.

[0086] In the above embodiment, the first support portion 13 and the second support portion 14 are both provided on the fixed base 1, and the first support portion 13 and the second support portion 14 extend circumferentially and are not closed, that is, they are provided with a first opening and a second opening. The third support portion 21 and the fourth support portion 22 are provided on the rotating base 2, and have the same structure as the first support portion 13 and the second support portion 14, and also have a first opening and a second opening. In addition, the stop portion 12 is provided on the outer edge of the fixed base 1 facing the rotating base 2 and extends circumferentially and is not closed. The mounting shaft 11 is provided in the middle position of the fixed base 1 facing the rotating base 2.

[0087] With the above structure, one end of the first elastic member 3 made of a spiral spring abuts against the blocking portion 12, and the other end abuts against the first support portion 13 and the third support portion 21; one end of the second elastic member 4 made of a spiral spring abuts against the mounting shaft 11, and the other end abuts against the second support portion 14 and the fourth support portion 22.

[0088] In order to limit the relative position of the rearview mirror in the third direction, preferably, a mounting groove 24 is opened in the middle position of the side wall of the rotating seat 2 away from the fixed seat 1, and a third elastic member 5 is installed in the mounting groove 24. The two ends of the third elastic member 5 respectively contact the bottom of the mounting groove 24 and the rearview mirror, which is used to limit the movement of the rearview mirror in the third direction.

[0089] With the above structure, when the rearview mirror has a tendency to move or is in motion in the third direction, the rearview mirror can compress the third elastic member 5, thereby limiting the relative position of the rearview mirror. After the force on the rearview mirror in the third direction disappears, the rearview mirror returns to its relative position under the action of the third elastic member 5.

[0090] In an optional embodiment, preferably, a fixing mortise 6 is provided between the third elastic member 5 and the rearview mirror. The fixing mortise 6 not only completes the connection of the rearview mirror structure, but also forms a stable space with the mounting groove 24 for mounting the third elastic member 5, thereby making the movement of the rearview mirror structure in the third direction more stable.

[0091] In the above embodiment, the third elastic member 5 is installed in the mounting groove 24. Preferably, the third elastic member 5 is made of a compression spring. The compression spring structure allows the third elastic member 5 to be stably installed in the mounting groove 24 and can provide effective resistance and restoring force to the movement of the rearview mirror.

[0092] In the above embodiment, the first elastic member 3 is provided to restrict the movement of the rotating base 2 in the first direction, and the second elastic member 4 is provided to restrict the movement of the rotating base 2 in the second direction. Preferably, the first and second directions lie in the same plane, and the third direction is perpendicular to the plane containing the first and second directions. In other words, the third elastic member restricts movement of the rearview mirror in the third direction. The first elastic member 3, the second elastic member 4, and the third elastic member 5 can restrict the movement of the rotating base in two mutually perpendicular planes.

[0093] according to Figure 2 , those skilled in the art can arrange a groove on the side of the fixed seat 1 facing the rotating seat 2, and a protrusion on the side of the rotating seat 2 facing the fixed seat 1. The positions of the protrusion and the groove are arranged correspondingly. When the rotating seat 2 is in the initial position, the protrusion is inserted into the groove, so that the installation position of the rotating seat 2 can be positioned. The protrusion can slide out of the groove during the rotation of the rotating seat 2. That is, in an embodiment, the bottom of the installation groove 24 can be arranged to be movably connected, so that the third elastic member is squeezed during the sliding out process of the protrusion, so that the third elastic member limits the relative position of the rotating seat 1.

[0094] By means of the above structure, the initial installation position of the rotating base 2 can be positioned without interfering with the subsequent rotation of the rotating base 2 .

[0095] according to Figure 9 and Figure 11 A person skilled in the art can provide multiple protrusions and multiple receiving grooves, wherein the multiple protrusions and the multiple receiving grooves are opposite to each other. When the rotating base 2 is in the initial position, the multiple protrusions are respectively inserted into the corresponding receiving grooves. When the rotating base 2 rotates, the protrusions can slide out of the corresponding receiving grooves.
