Description

[0001] This application is a divisional application of application number 202211191316.4 filed on September 28, 2022, entitled "Mirror Angle Adjustment Device and Bathroom Mirror". Technical Field

[0002] This invention relates to the field of bathroom product technology, and in particular to a mirror angle adjustment device and a bathroom mirror. Background Technology

[0003] Bathroom mirrors can be equipped with an adjustable mirror body to accommodate users of different heights. In related technologies, hinges and adjustment components can be spaced apart on the back side of the mirror body. The mirror body can be rotated around the hinge axis by driving the component connected to the mirror body in the adjustment component through the drive component. Alternatively, the mirror body can be manually pushed to rotate around the hinge axis to move the component connected to the mirror body in the adjustment component. Theoretically, the rotation center of the component connected to the mirror body in the adjustment component should coincide with the center of the hinge axis. However, in actual installation, installation errors are inevitable, which usually cause the rotation center of the component connected to the mirror body in the adjustment component to be offset from the center of the hinge axis, thus preventing the adjustment action from being performed smoothly.

[0004] In addition, due to the dimensional error of the outer frame, the mirror is difficult to center relative to the outer frame after it is installed inside the frame, resulting in an unsightly appearance of the bathroom mirror.

[0005] Furthermore, after the lens body is installed inside the outer frame, the rotation of the two sides of the lens body relative to the outer frame may be inconsistent, resulting in poor stability of the lens body rotation. Summary of the Invention

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a mirror angle adjustment device. By machining teeth extending in an arc shape on a rack around the center of the hinge hole, the rotation center of the mounting component is ensured to be the center of the hinge hole, which coincides with the center of the first column. This greatly reduces the impact of installation errors and ensures smooth adjustment. The mirror body experiences balanced forces on both sides, allowing it to remain centered relative to the outer frame even with dimensional errors, thus ensuring the bathroom mirror's appearance is acceptable. The action of one adjustment component drives the other to move synchronously, resulting in good consistency between the two components and improving the stability of the mirror's rotation.

[0007] The present invention also provides a bathroom mirror including the above-described mirror angle adjustment device.

[0008] The first aspect of the present invention provides a mirror angle adjustment device, comprising: a fixing component including a housing and a first column, the first column being connected to the housing, the housing being mounted on an outer frame; an adjustment component including a gear, a rack, a mounting member, and a first elastic washer, the gear being mounted on the housing, the gear including an external gear ring, the external gear ring being rotatable relative to the housing; the rack having teeth extending in an arc shape, the teeth meshing with the external gear ring; a hinge hole being provided at one end of the mounting member, the first column being rotatably inserted into the hinge hole, the rack being connected to the other end of the mounting member, the rack being capable of driving the mounting member to rotate around the first column, the first column being rotatably inserted into ...

[0043] Reference Figures 1 to 6 The mirror angle adjustment device 10 provided in the first aspect embodiment of the present invention includes a fixing component 100 and an adjustment component 200, as shown below. Figures 2 to 6 The fixing component 100 includes a housing 110 and a first column 120, the first column 120 being connected to the housing 110, and the housing 110 being mounted on the outer frame 30; the adjusting component 200 includes a gear 210, a rack 220, a mounting member 230, and a first elastic washer 240, the gear 210 being mounted on the housing 110, the gear 210 including an outer gear ring 211, the outer gear ring 211 being rotatable relative to the housing 110; the rack 220 having teeth 22 extending in an arc shape. 1. The tooth 221 meshes with the outer gear ring 211; one end of the mounting member 230 has a hinge hole 231, the first column 120 is rotatably inserted into the hinge hole 231, the rack 220 is connected to the other end of the mounting member 230, the rack 220 can drive the mounting member 230 to rotate around the first column 120, the mounting member 230 is used to connect to the mirror body 20; the first elastic washer 240 is sleeved on the first column 120 and clamped between the mounting member 230 and the housing 110; see reference. Figure 1 There are two fixing components 100 and two adjusting components 200. The two fixing components 100 are respectively set on the opposite sides of the outer frame 30, and the two adjusting components 200 are respectively set on the opposite sides of the outer frame 30.

[0044] The mirror body angle adjustment device 10 includes a fixing component 100 and an adjustment component 200. The adjustment component 200 includes a mounting member 230 for mounting on the mirror body 20. One end of the mounting member 230 has a hinge hole 231, which engages with the first column 120 in the fixing component 100 to form a hinge structure. The other end of the mounting member 230 is connected to a rack 220. The rack 220 engages with a gear 210 to adjust the angle of the mirror body 20. By machining the arc-shaped teeth 221 on the rack 220 around the center of the hinge hole 231, the rotation center of the mounting member 230 is ensured to be the center of the hinge hole 231. The center of the hinge hole 231 coincides with the center of the first column 120, which can greatly reduce the impact of installation error and ensure the smooth operation of adjustment. In addition, there are two fixing components 100 and two adjusting components 200, which are respectively located on opposite sides of the outer frame 30. After installation, the first elastic pads 240 in the two adjusting components 200 are in a compressed state. The two first elastic pads 240 respectively abut against the two mounting parts 230 located on both sides of the mirror body 20. The mirror body 20 is subjected to balanced force on both sides, so that even if there is an error in the size of the outer frame 30, the mirror body 20 can still be centered relative to the outer frame 30, thereby ensuring the appearance of the bathroom mirror is qualified.

[0045] Furthermore, to improve the consistency of the movement of the adjustment components 200 located on opposite sides of the outer frame 30, refer to Figure 1 The mirror body angle adjustment device 10 also includes a connecting rod 400 and a coupling 500. One end of the connecting rod 400 is connected to the gear 210 of the adjustment component 200 on one side of the outer frame 30 through a coupling 500, and the other end of the connecting rod 400 is connected to the gear 210 of the adjustment component 200 on the other side of the outer frame 30 through another coupling 500. The movement of one adjustment component 200 can drive the other adjustment component 200 to move synchronously. The movements of the two adjustment components 200 are well consistent, which can improve the stability of the mirror body 20 rotation.

[0046] In some embodiments, the mirror angle adjustment device 10 can be adjusted electrically, see reference Figure 5 and Figure 6 The mirror angle adjustment device 10 may include a drive mechanism 300, which includes an output shaft 310 and a drive member 320 connected to each other. Specifically, the drive member 320 may be a motor, the output shaft 310 is connected to the external gear ring 211, and the drive member 320 is used to drive the output shaft 310 to rotate so as to drive the external gear ring 211 to rotate.

[0047] Furthermore, referring to Figure 6The housing 110 has a drive mounting cavity 116, in which the drive mechanism 300 is housed to facilitate the fixing of the drive mechanism 300; the fixing assembly 100 also includes a cover 140, which is fastened to the housing 110 to close the drive mounting cavity 116 and protect the drive mechanism 300; the outer wall of the drive mounting cavity 116 may have a wiring notch 115 for wiring of the drive mechanism 300.

[0048] Reference Figure 7 The gear 210 also includes a first clamping plate 212, a first damping plate 213, a rotating shaft 214, a second clamping plate 215, a second damping plate 216, and a third clamping plate 217. The first clamping plate 212 is connected to the inside of the external gear ring 211. The rotating shaft 214 is connected to the second clamping plate 215 and passes through the first clamping plate 212. The third clamping plate 217 is connected to the rotating shaft 214 and is located on the side of the first clamping plate 212 away from the second clamping plate 215. The first damping plate 213 and the second damping plate 216 are both sleeved on the rotating shaft 214 and are located between the second clamping plate 215 and the third clamping plate 217 and are clamped. The first clamping plate 212, the first damping plate 213, the second clamping plate 215, the second damping plate 216, and the third clamping plate 217 of the gear 210 can be assembled in various ways. These different combinations can be used with other structures to meet different application requirements. Specifically:

[0049] Reference Figure 7 The inner wall of the external gear ring 211 is provided with a first limiting groove 2111, and the second clamping plate 215 is provided with a limiting protrusion 2151; see reference Figure 5 The housing 110 has a second limiting groove 131. Furthermore, the fixing assembly 100 also includes a limiting boss 130 connected to the housing 110. The second limiting groove 131 is formed in the limiting boss 130. The second clamping plate 215 is provided with a limiting protrusion 2151. The gear 210 has a first mounting state, a second mounting state, and a third mounting state.

[0050] Reference Figure 8-A and Figure 8-BIn the first installation state, the first damping plate 213 is clamped between the first clamping plate 212 and the second clamping plate 215, and the second damping plate 216 is clamped between the first clamping plate 212 and the third clamping plate 217. The limiting protrusion 2151 is located outside the first limiting groove 2111. The two sides of the first clamping plate 212 are respectively attached to the first damping plate 213 and the second damping plate 216. When there is a relative rotational tendency between the combination of the outer gear ring 211 and the first clamping plate 212 and the combination of the third clamping plate 217, the rotating shaft 214 and the second clamping plate 215, the two sides of the first damping plate 213 and the two sides of the second damping plate 216 can generate frictional forces to prevent relative rotation. In the combination of the outer gear ring 211 and the first clamping plate 212, the two sides of the first clamping plate 212 are subjected to uniform frictional forces, resulting in higher operational stability.

[0051] In the first installation state, the limiting protrusion 2151 is not accommodated in the first limiting groove 2111 or the second limiting groove 131, and the gear 210 is compatible with both electric and manual drive modes. When driven electrically, the output shaft 310 of the drive mechanism 300 drives the combination of the gear 210's rotating shaft 214 and the second clamping plate 215 to rotate. The second clamping plate 215, located on both sides of the first damping plate 213, tends to rotate relative to the first clamping plate 212, causing frictional forces to be generated on both sides of the first damping plate 213 to resist this relative rotation. Under the frictional action of the first damping plate 213, the combination of the rotating shaft 214 and the second clamping plate 215 drives the combination of the external gear ring 211 and the first clamping plate 212 to rotate. Driven by the rotation of the external gear ring 211, the teeth 221 extending along the arc shape... The rack 220 can rotate along an arc shape. When driven manually, the user presses the lens body 20 to make the lens body 20 rotate. The lens body 20 pushes the rack 220, which has teeth 221 extending along an arc shape, to rotate. At this time, the combination of the rotating shaft 214 and the second clamping plate 215 connected to the output shaft 310 of the drive mechanism 300 remains stationary. However, the pressing force applied by the user to the lens body 20 can resist the frictional force of the first damping plate 213. Thus, the rack 220 can drive the combination of the outer gear ring 211 and the first clamping plate 212 to rotate while the combination of the rotating shaft 214 and the second clamping plate 215 remains stationary.

[0052] When the installation of the bathroom mirror requires the mirror body 20 to be compatible with both electric and manual drive adjustment, the gear 210 can be installed in the first installation state.

[0053] Reference Figure 9-A and Figure 9-B In the second installation state, the first damping plate 213 and the second damping plate 216 are both clamped between the first clamping plate 212 and the third clamping plate 217, and the limiting protrusion 2151 is accommodated in the first limiting groove 2111.

[0054] In the second installation state, the limiting protrusion 2151 is accommodated in the first limiting groove 2111. Therefore, the combination of the rotating shaft 214 and the second clamping plate 215 cannot rotate relative to the combination of the outer gear ring 211 and the first clamping plate 212. At this time, the gear 210 can only be driven by electric drive. The output shaft 310 of the drive mechanism 300 drives the gear 210 to rotate as a whole. Under the drive of the rotation of the outer gear ring 211, the teeth 221 extending along the arc shape can make the rack 220 rotate as a whole along the arc shape.

[0055] When the installation of the bathroom mirror requires that the mirror body 20 can only be adjusted by electric drive, the gear 210 can be installed in the second installation state.

[0056] Reference Figure 10-A and Figure 10-B In the third installation state, the first damping plate 213 and the second damping plate 216 are both clamped between the first clamping plate 212 and the second clamping plate 215, and the limiting protrusion 2151 is accommodated in the second limiting groove 131.

[0057] In the third installation state, the limiting protrusion 2151 is accommodated in the second limiting groove 131, so the combination of the rotating shaft 214 and the second clamping plate 215 cannot rotate relative to the box 110. At this time, the gear 210 can only be driven by manual drive. The pressing pressure applied by the user to the mirror body 20 can resist the friction of the first damping plate 213, so that the rack 220 can drive the combination of the outer gear ring 211 and the first clamping plate 212 to rotate while the combination of the rotating shaft 214 and the second clamping plate 215 remains stationary.

[0058] When the installation of the bathroom mirror requires that the mirror body 20 can only be adjusted by manual drive, the gear 210 can be installed in the third installation state.

[0059] In summary, the above-mentioned mirror angle adjustment device 10 can meet three usage requirements: electric adjustment only, manual adjustment only, and a combination of electric and manual adjustment. It has a wide range of applications and high versatility.

[0060] It is understandable that the first limiting groove 2111 on the inner wall of the outer gear ring 211 and the second limiting groove 131 of the box body 110 can be provided simultaneously, so that the gear 210 of the lens angle adjustment device 10 can be installed in the first installation state, the second installation state, or the third installation state; or the first limiting groove 2111 can be provided alone, so that the gear 210 of the lens angle adjustment device 10 can be installed in the first installation state or the second installation state; or the second limiting groove 131 can be provided alone, so that the gear 210 of the lens angle adjustment device 10 can be installed in the first installation state or the third installation state.

[0061] Furthermore, referring to Figure 7 The gear 210 also includes a second elastic washer 218, see reference. Figure 8-B The second elastic washer 218 is clamped between the third clamping plate 217 and the second damping plate 216. The second elastic washer 218 is deformed by the pressure of the third clamping plate 217, generating elastic force. This elastic force acts on the second damping plate 216, causing the second damping plate 216, the first clamping plate 212, and the first damping plate 213 to be pressed against the second clamping plate 215. The magnitude of the frictional force is determined by the normal force. By selecting different specifications of the second elastic washer 218, the clamping force of the second damping plate 216, the first clamping plate 212, and the first damping plate 213 can be adjusted, thereby adjusting the magnitude of the frictional force generated on both sides of the first damping plate 213 and the second damping plate 216, thus achieving the adjustment of the damping of the gear 210. The second elastic washer 218 can be selected according to the desired adjustment feel, etc.

[0062] It is understandable that the second elastic pad 218 can also be clamped between the second clamping plate 215 and the first damping plate 213, so as to press the second damping plate 216, the first clamping plate 212, and the first damping plate 213 together.

[0063] Furthermore, referring to Figure 7 and Figure 8-B The gear 210 also includes a bolt 219 and a nut 2191. The third clamping plate 217 is connected to the rotating shaft 214 by the bolt 219 and the nut 2191. The gear 210 may also include a washer 2192, which is clamped between the end of the bolt 219 and the third clamping plate 217.

[0064] In other embodiments, reference is made to Figure 11 The gear 210 also includes a first clamping plate 212, a first damping plate 213, a rotating shaft 214, and a second clamping plate 215. The first clamping plate 212 is connected to the inside of the outer gear ring 211, the rotating shaft 214 is connected to the second clamping plate 215, the rotating shaft 214 passes through the first clamping plate 212, and the first damping plate 213 is sleeved on the rotating shaft 214 and clamped between the first clamping plate 212 and the second clamping plate 215.

[0065] Reference Figure 3 and Figure 4When the mirror body angle adjustment device 10, equipped with the aforementioned gear 210, adjusts the swing angle of the mirror body 20 relative to the outer frame 30 by electric adjustment, the output shaft 310 of the drive mechanism 300 drives the combination of the rotating shaft 214 of the gear 210 and the second clamping plate 215 to rotate. The second clamping plate 215 and the first clamping plate 212, which are respectively located on both sides of the first damping plate 213, tend to rotate relative to each other, resulting in frictional force on both sides of the first damping plate 213 that resists this relative rotation. Under the frictional action of the first damping plate 213, the combination of the rotating shaft 214 and the second clamping plate 215 drives the combination of the outer gear ring 211 and the first clamping plate 212 to rotate. Driven by the rotation of the outer gear ring 211, the teeth 221 extending along the arc shape can make the rack 220 rotate along the arc shape as a whole, thereby driving the mirror body 20 to rotate and realizing the electric adjustment of the mirror body 20 angle.

[0066] When the mirror body angle adjustment device 10 equipped with the aforementioned gear 210 adjusts the swing angle of the mirror body 20 relative to the outer frame 30 by manual adjustment, the user presses the mirror body 20 to make the mirror body 20 rotate. The mirror body 20 pushes the rack 220, which has teeth 221 extending in an arc shape, to rotate. At this time, the combination of the rotating shaft 214 and the second clamping plate 215 connected to the output shaft 310 of the drive mechanism 300 remains stationary. However, the pressing force applied by the user to the mirror body 20 can resist the frictional force of the first damping plate 213. Thus, the rack 220 can drive the combination of the outer gear ring 211 and the first clamping plate 212 to rotate while the combination of the rotating shaft 214 and the second clamping plate 215 remains stationary, thereby realizing the manual adjustment of the mirror body 20 angle.

[0067] Figure 7 The gear 210 shown is compatible with both electric and manual adjustment of the lens body 20 angle. In special circumstances such as failure of the drive mechanism 300 or power failure, the user can still adjust the angle of the lens body 20 manually, which is highly convenient. Furthermore, when the lens body 20 is accidentally pressed while the drive mechanism 300 is stopped, the outer gear ring 211 of the gear 210 can still rotate, which can prevent damage to the drive mechanism 300.

[0068] It is understood that, furthermore, the cross-section of the part of the output shaft 310 that is inserted into the rotating shaft 214 should be set to a shape other than a circle, such as a polygon, a circle with straight edges, etc., and the rotating shaft 214 should have a hole whose cross-section corresponds to the cross-sectional shape and size of the output shaft 310, so that the output shaft 310 can drive the rotating shaft 214 to rotate.

[0069] Reference Figure 3 and Figure 4The rack 220 has a limiting groove 222. The fixing assembly 100 also includes a second column 150, which is housed in the limiting groove 222. The rack 220 is movable relative to the second column 150, and the second column 150 can abut against the inner wall of the limiting groove 222. (Refer to...) Figure 3 When the mirror body 20 is in a vertical position (i.e., at the minimum tilt angle), the second column 150 abuts against the inner wall of one end of the limiting groove 222, and the second column 150 can limit the rack 220 to its extreme position when the mirror body 20 is in a vertical position; refer to Figure 4 When the mirror body 20 is at its maximum tilt angle, the second column 150 abuts against the inner wall of the other end of the limiting groove 222. The second column 150 can limit the rack 220 to its extreme position when the mirror body 20 is at its maximum tilt angle, thereby improving the stability of the mirror body 20 and preventing the mirror body 20 from rotating in the opposite direction of its normal rotation direction when it is already in a vertical state, or from continuing to rotate in the direction of increasing angle when it is already at its maximum tilt angle, which would cause the rack 220 to disengage from the external gear ring 211. (Refer to...) Figures 2 to 5 The housing 110 has a gear mounting cavity 111 and a rack movable cavity 112 that are interconnected. The gear 210 is mounted in the gear mounting cavity 111. One end of the rack movable cavity 112 is open. The second column 150 is located at the open end of the rack movable cavity 112. The rack 220 is at least partially housed in the rack movable cavity 112 and can move within it. The rack 220 meshes with the outer gear ring 211 at the connection between the gear mounting cavity 111 and the rack movable cavity 112. The gear mounting cavity 111 and the rack movable cavity 112 can indicate the installation position of the gear 210 and the rack 220, making installation more convenient. In addition, the meshing point between the rack 220 and the outer gear ring 211 is located inside the housing 110, which can reduce the wear of dust and foreign objects on the rack 220 and the outer gear ring 211, and improve the reliability of use.

[0070] Furthermore, referring to Figure 4 The end of the rack's movable cavity 112 has a limiting wall 113, as shown in the reference. Figure 3 When the mirror body 20 is in a vertical state, one end of the rack 220 abuts against the limiting wall 113. The limiting wall 113 can limit the rack 220 to the extreme position when the mirror body 20 is in a vertical state, so as to further improve stability and prevent the mirror body 20 from rotating in the opposite direction of the normal rotation direction when it is in a vertical state, causing the rack 220 to disengage from the external gear ring 211.

[0071] Furthermore, referring to Figure 4The side of the rack movable cavity 112 has a guide wall 114 extending along the extension direction of the tooth 221. The guide wall 114 is arc-shaped. The side of the rack 220 fits against the guide wall 114. When the rack 220 rotates, the guide wall 114 can guide the rack 220, making the rotation of the rack 220 more stable.

[0072] When the fixing component 100 and the adjusting component 200 are installed on the outer frame 30, the positional relationship between the housing 110 and the rack 220 varies depending on the installation position. When the fixing component 100 and the adjusting component 200 are installed on one side or the opposite side of the outer frame 30, the positional relationship between the housing 110 and the rack 220 is mirror symmetrical. Based on this, refer to Figure 3 The box body 110 has a gear mounting cavity 111 and two rack movable cavities 112. The gear mounting cavity 111, the two rack movable cavities 112, and the first column 120 and the second column 150 are all symmetrically arranged about the same axis of symmetry a. It should be noted that the first column 120 and the second column 150 are two cylinders of the same shape and size. During installation, depending on the installation position of the box body 110, the location of the gear 210 on which side of the axis of symmetry a in the gear mounting cavity 111, the location of the rack 220 in which rack movable cavity 112, the location of the second column 150 housed in the limiting groove 222, and the location of the first column 120 inserted into the hinge hole 231 can be selected. Therefore, it is unnecessary to produce two different box bodies 110 to accommodate installation in two opposite positions; only one box body 110 needs to be produced to meet the installation requirements of both opposite positions, saving mold-making costs.

[0073] It is understandable that the housing 110 can also be configured to have two gear mounting cavities 111 and two rack movable cavities 112, with the two gear mounting cavities 111, the two rack movable cavities 112, and the first column 120 and the second column 150 all symmetrically arranged about the same axis of symmetry.

[0074] Reference Figure 12 The bathroom mirror provided in the second aspect of the present invention includes an outer frame 30, a mirror body 20, and a mirror body angle adjustment device 10 provided in any embodiment of the first aspect of the present invention. The mirror body 20 is rotatably connected to the outer frame 30 through the mirror body angle adjustment device 10. Using the mirror body angle adjustment device 10 provided in the first aspect of the present invention, on the one hand, the rotation center of the mounting component 230 of the mirror body angle adjustment device 10 is highly consistent with the center of the column 120 serving as the rotation axis, which can greatly reduce the impact of installation errors and ensure the smooth adjustment of the mirror body 20 of the bathroom mirror; on the other hand, the first elastic pad 240 in the mirror body angle adjustment device 10 can center the mirror body 20 relative to the outer frame 30, resulting in a high appearance qualification rate for the bathroom mirror.

[0075] It is understandable that the angle adjustment range of the bathroom mirror body 20 is not limited and can be set according to actual needs. In some embodiments, the angle adjustment range of the mirror body 20 can be set to 0° to 15°. When the mirror body 20 is tilted, the mirror surface faces downward. The angle adjustment range of 0° to 15° can serve a large number of users of different heights. In addition, the width of the outer frame 30 is relatively narrow, which can save the space occupied by the bathroom mirror.

[0076] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
