Description

Technical Field

[0001] This invention relates to the automotive field, and in particular to a folding and limiting structure for an exterior rearview mirror and a vehicle thereof. Background Technology

[0002] Rearview mirrors are tools that allow drivers to directly obtain external information about the rear, sides, and bottom of the vehicle while seated in the driver's seat. To facilitate driver operation, prevent traffic accidents, and ensure personal safety, all countries mandate the installation of rearview mirrors on vehicles, and all rearview mirrors must be adjustable.

[0003] Interior rearview mirror: The interior rearview mirror is fixed inside the vehicle and used to observe the view directly behind the vehicle or the interior of the passenger compartment. It is usually mounted on the inside of the windshield or the roof. Exterior rearview mirror: The exterior rearview mirror is fixed on both sides of the vehicle and used to observe the view to the sides and rear. It is usually mounted on the doors, but can also be mounted on the fenders or hood.

[0004] In the relevant technologies, firstly, some exterior rearview mirrors have no positioning structure during the folding process and are in a completely loose state, resulting in poor perception; secondly, some exterior rearview mirrors have a folding direction that is basically the same as the left and right adjustment direction of the lens, and both are driven by motors, which results in cost waste. Summary of the Invention

[0005] This invention provides an exterior rearview mirror folding limiting structure and a vehicle to address two issues in related technologies: firstly, some exterior rearview mirrors lack a limiting structure during folding and are in a completely loose state; secondly, some exterior rearview mirrors are driven by a motor, resulting in cost waste.

[0006] In a first aspect, an exterior rearview mirror folding and limiting structure is provided, comprising:

[0007] A base for mounting on a vehicle body, the base having a mounting component, the mounting component having a first limiting portion, the first limiting portion extending in an arc shape;

[0008] A bracket for mounting an exterior rearview mirror is mounted on the mounting component and can rotate along the extension direction of the first limiting portion. The bracket is provided with an elastic telescopic component, and the elastic telescopic component is fixed with a second limiting portion.

[0009] When the bracket is subjected to force and rotates, the bracket drives the second limiting part to move on the first limiting part, and causes the elastic telescopic member to reciprocate and extend; when the force on the bracket is removed, the elastic force of the elastic telescopic member pushes the second limiting part to be limited to the first limiting part, so as to restrict the rotation of the bracket.

[0010] In some embodiments, the first limiting portion includes a first wave segment, and the extension direction of the first wave segment is consistent with the extension direction of the first limiting portion;

[0011] The second limiting part includes a limiting block, on which a second wave segment is provided. The crest of the second wave segment matches the trough of the first wave segment, and the trough of the second wave segment matches the crest of the first wave segment.

[0012] The elastic telescopic component is fixed between the limiting block and the bracket.

[0013] In some embodiments, the bracket is fixed with a connecting plate, the connecting plate has a groove, and the two opposite inner sidewalls of the groove have sliding grooves.

[0014] At least one limiting strip is provided on each of the opposite sides of the limiting block, and the two limiting strips correspond one-to-one with the two sliding grooves and are slidably installed in the corresponding sliding grooves;

[0015] The elastic telescopic member is disposed between the inner bottom wall of the groove and the limiting block.

[0016] In some embodiments, the connecting plate includes: a first plate body and a second plate body;

[0017] The first plate and the second plate are stacked together and can be detachably fixed together. The second plate has a through hole that is projected along the thickness direction of the connecting plate. The part of the first plate that overlaps with the through hole forms the inner bottom wall of the groove.

[0018] The two grooves are spaced apart on the opposite inner sidewalls of the through hole, and one end of each groove near the first plate extends through the through hole, while the other end is a blocking end.

[0019] One end of the elastic telescopic member is fixed to the first plate.

[0020] In some embodiments, the second limiting part and the elastic telescopic member are a set of limiting components;

[0021] Along the rotation direction of the bracket, at least two sets of limiting components are provided at intervals on the bracket, and the second limiting part of both sets of limiting components is in limiting cooperation with the first limiting part.

[0022] In some embodiments, there are two first limiting parts, which are distributed at intervals along the rotation direction of the bracket, and the two first limiting parts correspond one-to-one with two sets of limiting components and are limited and cooperated with the corresponding limiting components.

[0023] In some embodiments, along the rotation direction of the bracket, the bracket has two connecting plates fixed at intervals, and the two sets of limiting components correspond one-to-one with the two connecting plates and are fixed to the corresponding connecting plates;

[0024] A stop block is fixed on the mounting component, and the stop block is located between the two connecting plates along the rotation direction of the bracket;

[0025] When one of the connecting plates abuts against the blocking block, the exterior rearview mirror is in its minimum retracted state; when the other connecting plate abuts against the blocking block, the exterior rearview mirror is in its maximum extended state.

[0026] In some embodiments, limit protrusions are provided on both sides of the abutment block along the rotation direction of the bracket; limit recesses are provided on one side of both connecting plates, and both limit recesses are adapted to the limit protrusions.

[0027] In some embodiments, the elastic telescopic element includes a spring or an elastic sheet.

[0028] Secondly, a vehicle is provided, including the exterior rearview mirror folding limiting structure as described above.

[0029] The beneficial effects of the technical solution provided by this invention include: under the elastic force of the elastic telescopic member, the second limiting part is matched with the first limiting part, so that the exterior rearview mirror does not easily rotate or deviate under the influence of external factors, ensuring that the exterior rearview mirror is stationary; when the exterior rearview mirror needs to be adjusted, the exterior rearview mirror can be manually rotated, driving the bracket to rotate on the mounting part of the base, so that the second limiting part slides on the surface of the first limiting part. When the exterior rearview mirror is rotated to the designated position, the second limiting part is tightly limited on the first limiting part under the elastic force of the elastic telescopic member, ensuring that the exterior rearview mirror is stationary. This realizes that the exterior rearview mirror can be limited at any position during the folding process without affecting the normal folding function of the exterior rearview mirror, while saving costs.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] This invention provides an exterior rearview mirror folding limiting structure and a vehicle to address two issues in related technologies: firstly, some exterior rearview mirrors lack a limiting structure during folding and are in a completely loose state; secondly, some exterior rearview mirrors are driven by a motor, resulting in cost waste.

[0040] like Figure 1 and Figure 2As shown, this embodiment of the invention provides a folding and limiting structure for an exterior rearview mirror, which may include: a base 1 for mounting on a vehicle body, a mounting member 2 on the base 1, a first limiting part 3 on the mounting member 2, the first limiting part 3 extending in an arc shape; and a bracket 4 for mounting the exterior rearview mirror, the bracket 4 being mounted on the mounting member 2 and rotatable along the extending direction of the first limiting part 3, an elastic telescopic member 5 on the bracket 4, and a second limiting part 6 fixed to the elastic telescopic member 5; when the bracket 4 is subjected to force and rotates, the bracket 4 drives the second limiting part 6 to move on the first limiting part 3, and causes the elastic telescopic member 5 to reciprocate and extend; when the force on the bracket 4 is removed, the elastic force of the elastic telescopic member 5 pushes the second limiting part 6 to be limited to the first limiting part 3, thereby restricting the rotation of the bracket 4.

[0041] Specifically, when the exterior rearview mirror is manually rotated, the bracket 4 rotates on the mounting part 2, causing the second limiting part 6 on the bracket 4 to move on the surface of the first limiting part 3. During this movement, the second limiting part 6 extends and retracts in the radius of the bracket 4's rotation, causing the elastic telescopic member 5 to extend and retract. When the exterior rearview mirror is rotated to the designated position, the bracket 4 remains stationary. At this time, the elastic telescopic member 5, under its own elastic force, tightly restricts the second limiting part 6 connected to the first limiting part 3, ensuring the exterior rearview mirror remains stationary and preventing it from rotating or shifting during vehicle bumps, thus affecting driver safety. This design allows the exterior rearview mirror to be limited to any position during folding without affecting its normal folding function, while also saving costs.

[0042] In this embodiment, the mounting component 2 can be a cylinder, the bracket 4 is rotatably mounted on the top of the cylinder, and the first limiting part 3 is provided on the side wall of the cylinder. In some optional embodiments, such as... Figure 3 As shown, the mounting component 2 can also be a ring, with the bracket 4 rotatably mounted inside the ring, and the first limiting part 3 disposed on the outer wall of the ring; in some optional embodiments, the bracket 4 can also be rotatably mounted on the outer wall of the ring, with the first limiting part 3 disposed on the inner wall of the ring, and the second limiting part 6 similarly disposed inside the ring to cooperate with the first limiting part 3 for limiting, which can hide the connection between the base 1 and the bracket 4, preventing damage from external impacts, and making the appearance of the rearview mirror with the folding limiting structure more concise and beautiful.

[0043] In some embodiments, such as Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the first limiting part 3 may include a first wave segment, the extension direction of which is consistent with the extension direction of the first limiting part 3; the second limiting part 6 may include a limiting block 61, on which a second wave segment is provided, the crest of which matches the trough of the first wave segment, and the trough of which matches the crest of the first wave segment; the elastic telescopic member 5 is fixed between the limiting block 61 and the bracket 4. When the bracket 4 rotates, it drives the limiting block 61 to rotate synchronously. During the movement of the limiting block 61, the second wave segment on it moves on the surface of the first wave segment. Since the crests and troughs of both the first and second wave segments are arc-shaped, the second wave segment of the limiting block 61 can move smoothly on the first wave segment. After the movement stops, the crest of the second wave segment is located within the trough of the first wave segment, and the crest of the first wave segment is located within the trough of the second wave segment, achieving the limiting and fixing effect of the limiting block 61, thereby ensuring that the exterior rearview mirror will not easily shift.

[0044] In some optional embodiments, the multiple troughs of the first wave segment can be distributed at intervals along the arc-shaped trajectory of the first limiting part 3, while the peaks between two adjacent troughs are eliminated, so that there is a smooth arc surface between two adjacent troughs. Thus, as the limiting block 61 moves to the next trough, there is no limiting effect in the middle, making the movement of the limiting block 61 smoother. At the same time, the limiting and stationary state of the exterior rearview mirror is achieved only when it moves into the interior of the next trough.

[0045] In some embodiments, such as Figure 4 , Figure 5 and Figure 6 As shown, the bracket 4 is fixed with a connecting plate 41, the connecting plate 41 has a groove 42, and the two opposite inner sidewalls of the groove 42 are each provided with a sliding groove 43; at least one limiting strip 62 is provided on each opposite side of the limiting block 61, the two limiting strips 62 correspond one-to-one with the two sliding grooves 43, and are slidably installed in the corresponding sliding grooves 43; the elastic telescopic member 5 is disposed between the inner bottom wall of the groove 42 and the limiting block 61. The limiting block 61 is slidably installed in the sliding groove 43 through the limiting strips 62, thus at least partially sliding in the groove 42 of the connecting plate 41, and the elastic telescopic member 5 is located between the inner bottom wall of the groove 42 and the limiting block 61. The elastic force of the elastic telescopic member 5 always keeps pushing the second wave segment on the limiting block 61 to be in contact with the first wave segment, so that the exterior rearview mirror remains in a limited state when stationary, thereby ensuring the stationary effect of the exterior rearview mirror.

[0046] Specifically, there can be two limit strips 62 on each side of the limit block 61 to ensure the stability of the sliding of the limit block 61.

[0047] In some embodiments, such as Figure 4 and Figure 5 As shown, the connecting plate 41 may include: a first plate 411 and a second plate 412; the first plate 411 and the second plate 412 are stacked and detachably fixed together; the second plate 412 has a through hole projected along the thickness direction of the connecting plate 41; the portion of the first plate 411 overlapping with the through hole forms the inner bottom wall of the groove 42; two sliding grooves 43 are distributed at intervals on the opposite inner sidewalls of the through hole; one end of each sliding groove 43 near the first plate 411 extends through the through hole, and the other end is a blocking end; one end of the elastic telescopic member 5 is fixed to the first plate 411. In the assembly of the connecting plate 41, the elastic telescopic component 5, and the limiting block 61, the limiting strip 62 of the limiting block 61 is installed in the sliding groove 43, which passes through one end of the surface of the second plate 412. The elastic telescopic component 5 is then fixed on the portion of the first plate 411 that overlaps with the through hole. The first plate 411 and the second plate 412 are then assembled to complete the assembly hole for the elastic telescopic component 5 and the limiting block 61. This process is convenient and the structure is rationally designed. After prolonged use, the elastic telescopic component 5 may experience elastic fatigue and fail to provide strong elastic support. In this case, the first plate 411 and the second plate 412 can be disassembled and the elastic telescopic component 5 removed for timely replacement. This ensures sufficient elastic force from the elastic telescopic component 5 and guarantees the effective limiting fit between the second wave segment and the first wave segment on the limiting block 61.

[0048] In some optional embodiments, the first plate 411 and the second plate 412 can be fixed together by bolts or by snap-fit, etc., to ensure that the first plate 411 and the second plate 412 can be easily disassembled and separated.

[0049] In some embodiments, the second limiting part 6 and the elastic telescopic member 5 can be a set of limiting components; along the rotation direction of the bracket 4, at least two sets of limiting components are spaced apart on the bracket 4, and the second limiting part 6 of both sets of limiting components cooperates with the first limiting part 3 for limiting. Specifically, along the arcuate trajectory direction of the first limiting part 3, the bracket 4 is provided with two sets of limiting components, each set of limiting components can include the elastic telescopic member 5 and the second limiting part 6, and both sets of limiting components cooperate with the first limiting part 3 for limiting, which can greatly improve the limiting effect of the exterior rearview mirror in a stationary state. When facing some off-road vehicles, trains or trucks, it can play a good limiting effect and prevent the exterior rearview mirror from rotating and deviating easily during bumpy road conditions.

[0050] In some embodiments, there are two first limiting parts 3, which are distributed at intervals along the rotation direction of the bracket 4, and the two first limiting parts 3 correspond one-to-one with two sets of limiting components and are limited and cooperated with the corresponding limiting components.

[0051] In some optional embodiments, a set of limiting components and the first limiting part 3 constitute a set of limiting units. The folding limiting structure of the exterior rearview mirror is provided with three or more sets, and the multiple sets of limiting units are distributed at intervals along the rotation direction of the bracket 4. This can greatly improve the limiting effect of the exterior rearview mirror in a stationary state, thereby greatly improving the reliability of the exterior rearview mirror and ensuring that it can play a good stationary limiting role in harsh road conditions.

[0052] In some embodiments, along the rotation direction of the bracket 4, two connecting plates 41 are fixedly fixed at intervals on the bracket 4, and two sets of limiting components correspond one-to-one with the two connecting plates 41 and are fixed to the corresponding connecting plates 41; for example Figure 3 and Figure 4 As shown, a stop block 21 is fixed on the mounting component 2. Along the rotation direction of the bracket 4, the stop block 21 is located between the two connecting plates 41. When one of the connecting plates 41 abuts against the stop block 21, the exterior rearview mirror is in its minimum retracted state; when the other connecting plate 41 abuts against the stop block 21, the exterior rearview mirror is in its maximum extended state. Specifically, the bracket 4 is provided with two sets of limiting components along the rotation direction. Both sets of limiting components are fixed to the bracket 4 by a connecting plate 41, and along the rotation direction of the bracket 4, the stop block 21 is located between the two limiting components. When the exterior rearview mirror needs to be retracted, such as... Figure 1 As shown, rotating the bracket 4 counterclockwise causes the connecting plate 41 at the rear to abut against the rear side of the stop block 21 on the right, thus achieving the maximum retracted state of the exterior rearview mirror; when it is necessary to extend the exterior rearview mirror to its maximum state, rotating the bracket 4 clockwise moves the connecting plate 41 at the front (… Figure 1 (Not shown in the image) Rotate clockwise until it abuts against the front of the right-side stop block 21, thus maximizing the unfolding of the exterior rearview mirror. This prevents the exterior rearview mirror from colliding with the vehicle body and damaging the paint if the rotation angle is too large.

[0053] In some embodiments, along the rotation direction of the bracket 4, limiting protrusions are provided on both sides of the abutment block 21; limiting recesses are provided on one side of each of the two connecting plates 41, and both limiting recesses are adapted to the limiting protrusions. For example, Figure 4As shown, when the left connecting plate 41 abuts against the stop block 21, the limiting recess groove on the connecting plate 41 will cooperate with the limiting protrusion of the stop block 21 to ensure that the exterior rearview mirror is in its minimum retracted state, thereby improving the limiting effect between the connecting plate 41 and the stop block 21, and further improving the limiting effect of the exterior rearview mirror in its retracted and stationary state; when the right connecting plate 41 ( Figure 4 When the (not shown) abuts against the stop block 21, similarly, the limiting recess groove on the right connecting plate 41 will cooperate with the limiting protrusion of the stop block 21 to ensure that the exterior rearview mirror can maintain the limiting effect when it is in the maximum unfolded state, and prevent the exterior rearview mirror from easily loosening and shifting when it is in the maximum unfolded state and the lowest retracted state.

[0054] In some embodiments, the elastic telescopic member 5 includes a spring or an elastic sheet. The elastic sheet can be a metal elastic sheet, which ensures good elasticity and a long service life.

[0055] In some alternative embodiments, the elastic telescopic member 5 may also be a spring telescopic rod or an elastic rubber material.

[0056] In some embodiments, the present invention may also provide a vehicle including the exterior rearview mirror folding limiting structure as described in the above embodiments.

[0057] Among them, such as Figure 1 and Figure 2 As shown, the folding and limiting structure of the exterior rearview mirror may include: a base 1, which is used to install on the vehicle body, and a mounting member 2 is provided on the base 1. The mounting member 2 is provided with a first limiting part 3, which extends in an arc shape; a bracket 4, which is used to install the exterior rearview mirror. The bracket 4 is installed on the mounting member 2 and can rotate along the extending direction of the first limiting part 3. An elastic telescopic member 5 is provided on the bracket 4, and a second limiting part 6 is fixed to the elastic telescopic member 5. When the bracket 4 is subjected to force and rotates, the bracket 4 drives the second limiting part 6 to move on the first limiting part 3, and causes the elastic telescopic member 5 to reciprocate and extend; when the force on the bracket 4 is removed, the elastic force of the elastic telescopic member 5 pushes the second limiting part 6 to be limited to the first limiting part 3, thereby restricting the rotation of the bracket 4.

[0058] Specifically, when the exterior rearview mirror is manually rotated, the bracket 4 rotates on the mounting part 2, causing the second limiting part 6 on the bracket 4 to move on the surface of the first limiting part 3. During this movement, the second limiting part 6 extends and retracts in the radius of the bracket 4's rotation, causing the elastic telescopic member 5 to extend and retract. When the exterior rearview mirror is rotated to the designated position, the bracket 4 remains stationary. At this time, the elastic telescopic member 5, under its own elastic force, tightly restricts the second limiting part 6 connected to the first limiting part 3, ensuring the exterior rearview mirror remains stationary and preventing it from rotating during vehicle bumps, thus affecting driver safety. This achieves the ability to limit the exterior rearview mirror to any position during folding without affecting its normal folding function, while also saving costs.

[0059] In this embodiment, the mounting component 2 can be a cylinder, with the bracket 4 rotatably mounted on the top of the cylinder. The first limiting part 3 is located on the side wall of the cylinder. In some optional embodiments, the mounting component 2 can also be a ring, with the bracket 4 rotatably mounted inside the ring, and the first limiting part 3 located on the outer side wall of the ring. Figure 3 As shown, the bracket 4 can also be rotatably installed on the outer side wall of the ring. The first limiting part 3 is set on the inner side wall of the ring, and the second limiting part 6 is similarly set inside the ring to cooperate with the first limiting part 3 for limiting. This allows the connection between the base 1 and the bracket 4 to be hidden, preventing damage from external impacts. At the same time, it makes the appearance of the rearview mirror with the folding limiting structure more concise and beautiful.

[0060] In some embodiments, such as Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, the first limiting part 3 may include a first wave segment, the extension direction of which is consistent with the extension direction of the first limiting part 3; the second limiting part 6 may include a limiting block 61, on which a second wave segment is provided, the crest of which matches the trough of the first wave segment, and the trough of which matches the crest of the first wave segment; the elastic telescopic member 5 is fixed between the limiting block 61 and the bracket 4. When the bracket 4 rotates, it drives the limiting block 61 to rotate synchronously. During the movement of the limiting block 61, the second wave segment on it moves on the surface of the first wave segment. Since the crests and troughs of both the first and second wave segments are arc-shaped, the second wave segment of the limiting block 61 can move smoothly on the first wave segment. After the movement stops, the crest of the second wave segment is located within the trough of the first wave segment, and the crest of the first wave segment is located within the trough of the second wave segment, achieving the limiting and fixing effect of the limiting block 61, thereby ensuring that the exterior rearview mirror will not easily shift.

[0061] In some optional embodiments, the multiple troughs of the first limiting segment can be distributed at intervals along the arc-shaped trajectory of the first limiting part 3, while the peaks between two adjacent troughs are eliminated, so that the area between two adjacent troughs forms a smooth arc surface. Thus, as the limiting block 61 moves to the next trough, there is no limiting effect in the middle, making the movement of the limiting block 61 smoother. At the same time, the limiting and stationary state of the exterior rearview mirror is achieved only when it moves into the next trough.
