Description

Technical Field

[0001] The utility model relates to the field of automobile accessories, in particular to an automobile rearview mirror capable of increasing the visual field. Background Art

[0002] The car rearview mirror is an important component of the car. It is located on the left and right sides of the car head and the front of the car interior. It provides the driver with external information behind, to the sides and below the car, allowing the driver to indirectly see the situation in these positions. It plays the role of a "second eye" and greatly expands the driver's field of vision.

[0003] When the existing car rearview mirror needs to be replaced with a rearview mirror of a different curvature, the entire rearview mirror needs to be disassembled for replacement, which requires the help of professional car maintenance personnel to ensure that the replacement process is correct. Especially for drivers who need to frequently replace or adjust the rearview mirror, the operation is more troublesome and also increases the cost. Utility Model Content

[0004] The purpose of the utility model is to provide a car rearview mirror which can increase the field of vision, so as to solve the problems raised in the above-mentioned background technology.

[0005] To solve the above technical problems, the utility model provides a car rearview mirror that can increase the field of view, including a shell and a rearview mirror body. An extrusion assembly is arranged inside the shell, and the extrusion assembly includes a servo motor. A worm is connected to the driving end of the servo motor, and the worm is meshed with a worm wheel. A gear is arranged on one side of the worm wheel, and the gear is meshed with a rack.

[0006] Furthermore, a connecting rod is installed on the worm gear, the gear is fixedly installed on one end of the connecting rod, and the other end of the connecting rod is rotatably connected to the inner wall of the shell.

[0007] Furthermore, the rack is installed with a U-shaped block, the inner wall of the U-shaped block is installed with a telescopic spring, and the other end of the telescopic spring is installed with a clamping plate.

[0008] Furthermore, mounting plates are installed on both sides of the rearview mirror body, the mounting plates are symmetrically arranged, and the mounting plates are arranged between the U-shaped block and the clamping plate.

[0009] Furthermore, guide rods are fixedly mounted on two opposite inner walls of the shell, the rack is slidably connected to the outer wall of the guide rod, a mounting block is mounted on the inner bottom wall of the shell, and one end of the worm away from the servo motor is rotatably connected to the mounting block.

[0010] Furthermore, a threaded rod is installed on one side of the gear, a sliding sleeve is threadedly connected to the outer wall of the threaded rod, and the sliding sleeve is rotatably connected to the side of the rearview mirror body opposite to the gear.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. In the utility model, when the driver needs to expand the field of vision, the servo motor can be started by the single chip microcomputer. The servo motor makes the worm wheel rotate counterclockwise through the meshing of the worm and the worm wheel, and the connecting rod connects the worm wheel to drive the gear to rotate counterclockwise synchronously. The meshing of the gear and the rack makes the two racks move towards each other, thereby squeezing the two sides of the rearview mirror body to form a convex surface on the back to expand the field of vision. The special curved surface of the rearview mirror body and the law of reflection enhance the visual effect, further expand the viewing angle, and increase the adjustment rate, while reducing the expenditure of labor costs.

[0013] 2. In the utility model, the threaded rod rotates under the drive of the gear, and the sliding sleeve is installed on the rearview mirror body and can rotate but not detach. The sliding sleeve moves linearly under the drive of the threaded rod, away from the gear, and pushes the rearview mirror body to move in the opposite direction. This design prevents the formation of a concave surface when squeezing the rearview mirror body. The threaded rod and the sliding sleeve assist the squeezing assembly to achieve the effect of expanding the field of view. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 - Figure 6 , the utility model provides a technical solution:

[0025] See also Figure 1 - Figure 3 The present invention discloses a car rearview mirror capable of increasing the field of vision, comprising a shell 1 and a rearview mirror body 3. An extrusion assembly 2 is arranged inside the shell 1. The extrusion assembly 2 comprises a servo motor 201. The servo motor 201 is mounted on the inner bottom wall of the shell 1. A worm 202 is connected to the driving end of the servo motor 201. The worm 202 is meshedly connected to a worm wheel 203. A gear 204 is arranged on one side of the worm wheel 203. The gear 204 is meshedly connected to two racks 205. The racks 205 are slidably arranged in the shell 1.

[0026] If the driver needs to expand the field of vision, the servo motor 201 can be started by controlling the single chip microcomputer. The worm 202 and the worm wheel 203 are meshed with each other. The servo motor 201 drives the worm wheel 203 to rotate counterclockwise through the worm 202. The worm wheel 203 drives the gear 204 to rotate counterclockwise synchronously through the connecting rod 4. The gear 204 and the rack 205 are meshed with each other. The two racks 205 and the U-shaped block 6 move toward each other under the drive of the gear 204. The two sides of the rearview mirror body 3 are squeezed by the U-shaped blocks 6 moving toward each other. The side of the rearview mirror body 3 opposite to the gear 204 is bent to form a convex surface. The degree of bending of the rearview mirror body 3 can indeed expand the field of vision. The rearview mirror body 3, through its special curved shape and reflection law, makes the objects behind the mirror appear larger in the visual field, thereby expanding the viewing angle. The extrusion component 2 can quickly adjust the curvature of the rearview mirror body 3, improve the adjustment rate, and can adjust the curvature of the rearview mirror body 3 without the assistance of external force, while reducing the expenditure on labor costs.

[0027] The rearview mirror body 3 is made of flexible glass, which is a special material with transparency and flexibility and can be bent and compressed.

[0028] See also Figure 2 A connecting rod 4 is fixedly mounted on the worm gear 203 , a gear 204 is fixedly mounted on one end of the connecting rod 4 , and the other end of the connecting rod 4 is rotatably connected to the inner wall of the housing 1 .

[0029] The worm wheel 203 and the gear 204 are connected by the connecting rod 4, so as to realize the motion conversion and transmission from one component to another. This design enables the worm wheel 203 and the gear 204 to work together to complete the required mechanical action. The other end of the connecting rod 4 is rotatably connected to the inner wall of the housing 1, which increases the stability of the structure.

[0030] See also Figure 3-5 The rack 205 is fixedly mounted with a U-shaped block 6, the inner wall of the U-shaped block 6 is fixedly mounted with a telescopic spring 7, and the other end of the telescopic spring 7 is fixedly mounted with a clamping plate 8.

[0031] Place the mounting plate 12 between the U-shaped block 6 and the clamping plate 8. The elastic force of the telescopic spring 7 will push the clamping plate 8 toward the mounting plate 12, thereby fixing and clamping the mounting plate 12 to prevent the two sides of the rearview mirror body 3 from escaping from the running track of the worm gear 203 when the worm gear 203 pushes the two sides of the rearview mirror body 3.

[0032] See also Figure 3-5 Mounting plates 12 are fixedly mounted on both sides of the rearview mirror body 3 , and the mounting plates 12 are symmetrically arranged. The mounting plates 12 are arranged between the U-shaped block 6 and the clamping plate 8 .

[0033] The two ends of the rearview mirror body 3 are fixed by clamping the mounting plate 12, which facilitates the operation of the extrusion assembly 2. The rack 205 pushes the rearview mirror body 3 and directly fixes the mounting plate 12, thereby protecting the two sides of the rearview mirror body 3 and preventing the rearview mirror body 3 from bending and protruding. The places where the two sides of the rearview mirror body 3 are connected to the U-shaped block 6 and the telescopic spring 7 also bend.

[0034] See also Figure 2-3 The two opposite inner walls of the shell 1 are fixedly installed with guide rods 5, the rack 205 is slidably connected to the outer wall of the guide rod 5, the inner bottom wall of the shell 1 is fixedly installed with a mounting block 11, and the end of the worm 202 away from the servo motor 201 is rotatably connected to the mounting block 11.

[0035] The guide rod 5 provides a stable sliding track for the rack 205, ensuring the stability and linearity of the rack 205 during movement. This helps prevent the rack 205 from deflecting or shaking during movement, thereby improving the overall motion accuracy and reliability. The mounting block 11 serves as a fixed support point at one end of the worm 202, which can effectively enhance stability.

[0036] See also Figure 3 and Figure 6 A threaded rod 9 is fixedly mounted on one side of the gear 204 , and a sliding sleeve 10 is threadedly connected to the outer wall of the threaded rod 9 . The sliding sleeve 10 is rotatably connected to the side of the rearview mirror body 3 opposite to the gear 204 .

[0037] The threaded rod 9 rotates under the drive of the gear 204, and the sleeve 10 is arranged on the rearview mirror body 3 and can rotate but will not separate from the rearview mirror body 3. The sleeve 10 moves linearly in the direction away from the gear 204 under the drive of the threaded rod 9. The sleeve 10 pushes the rearview mirror body 3 in the opposite direction of the gear 204, which can prevent the threaded rod 9 and the sleeve 10 from bending toward the direction of the gear 204 when the two sides of the rearview mirror body 3 are squeezed, thereby forming a concave surface. The threaded rod 9 and the sleeve 10 play an auxiliary role in the extrusion assembly 2.

[0038] Working principle: If the driver needs to expand the field of vision, the servo motor 201 can be started by controlling the single-chip microcomputer. The worm 202 and the worm wheel 203 are meshed with each other. The servo motor 201 drives the worm wheel 203 to rotate counterclockwise through the worm 202. The worm wheel 203 drives the gear 204 to rotate counterclockwise synchronously through the connecting rod 4. The gear 204 and the rack 205 are meshed with each other. The two racks 205 and the U-shaped block 6 move toward each other under the drive of the gear 204. The two sides of the rearview mirror body 3 are squeezed, and the side of the rearview mirror body 3 opposite to the gear 204 is bent to form a convex surface. The degree of bending of the rearview mirror body 3 can indeed expand the field of vision. The rearview mirror body 3, through its special curved shape and reflection law, makes the objects behind the mirror appear larger in the visual field, thereby expanding the viewing angle. The extrusion component 2 can quickly adjust the curvature of the rearview mirror body 3, improve the adjustment rate, and can adjust the curvature of the rearview mirror body 3 without the assistance of external force, while reducing the expenditure on labor costs.

[0039] The rearview mirror body 3 is made of flexible glass, which is a special material with transparency and flexibility and can be bent and compressed.

[0040] The threaded rod 9 rotates under the drive of the gear 204, and the sleeve 10 is arranged on the rearview mirror body 3 and can rotate but will not separate from the rearview mirror body 3. The sleeve 10 moves linearly in the direction away from the gear 204 under the drive of the threaded rod 9. The sleeve 10 pushes the rearview mirror body 3 in the opposite direction of the gear 204, which can prevent the threaded rod 9 and the sleeve 10 from bending toward the direction of the gear 204 when the two sides of the rearview mirror body 3 are squeezed, thereby forming a concave surface. The threaded rod 9 and the sleeve 10 play an auxiliary role in the extrusion assembly 2.
