Description
Technical Field
[0001] The invention relates to the technical field of automobile rearview mirrors, and in particular to an automobile anti-collision rearview mirror. Background Art
[0002] The rearview mirror is located on the left and right sides of the car head. It reflects the situation behind, to the side and below the car, so that the driver can indirectly see the situation in these positions. It plays the role of "second eyes" and expands the driver's field of vision.
[0003] Due to factors such as narrow roads, it is very likely that the oncoming side of the rearview mirror will collide with each other when the car is driving on the opposite side. In most cases, the rearview mirror will turn to the side of the car body to reduce the impact force. Although the rearview mirror can deflect and unload the force at this time, the plastic shell on the oncoming side will still have a hard collision at the first moment of impact, and the vibration caused by the impact will also be transmitted to the lens, which requires a high quality of the lens. Summary of the invention
[0004] In order to solve the above problems, the present invention provides an automobile anti-collision rearview mirror, comprising a mirror seat, a mirror handle hinged on the mirror seat, a mirror cover connected to the mirror handle, a lens arranged on the mirror surface side of the mirror cover, a notch opposite to the front and back of the lens arranged on the front side of the mirror cover, an anti-collision seat arranged in the notch, a movable space left between the anti-collision seat and the lens, one end of the notch opening close to the mirror handle, the other end of the notch opening close to the side edge of the mirror cover, a rotating shaft installed on the end of the notch opening close to the mirror handle, one end of the anti-collision seat installed on the rotating shaft, the other end of the anti-collision seat reaches the side edge of the notch, the anti-collision seat protrudes outwardly toward the front side of the mirror cover, and when the protruding surface of the anti-collision seat is pressed, the anti-collision seat deflects toward the movable space;
[0005] An anti-collision lining is provided in the activity space, and the anti-collision lining is sandwiched between the hinged end of the anti-collision seat and the lens. When the anti-collision seat deflects toward the activity space, the anti-collision lining is squeezed by the inner surface, and the anti-collision lining is squeezed toward the thickness direction of the lens to perform a buffering action;
[0006] A hinged seat is provided at the middle position of the inner surface of the anti-collision seat, and a force rod is connected to the hinged seat. The other end of the force rod is connected to the end of the anti-collision lining along the length direction of the activity space. When the anti-collision seat deflects toward the activity space, the hinged seat is also used to drive the force rod to deflect toward the end of the anti-collision lining, and force is applied to the anti-collision lining from the end, so that the anti-collision lining performs a squeezing and buffering action in the length direction of the lens.
[0007] As a further preferred embodiment, a slope is provided on the front side of the mirror seat, the notch is opened on the slope, the anti-collision seat is transferred into the notch, and the anti-collision seat gradually protrudes outwards toward the terminal end direction of the slope.
[0008] As a further preference, the anti-collision liner is a rubber corrugated seat, the corrugation direction of which is arranged along the length direction of the activity space, and the force rod is connected to the end of the corrugation length of the anti-collision liner.
[0009] As further preferred, the anti-collision seat is a rubber seat.
[0010] As a further preference, a circle of anti-falling rubber is provided on the mirror surface end of the mirror cover, the mirror surface side of the lens is confined within the anti-falling rubber, and the back side of the lens is confined to the hinge seat and the anti-collision lining.
[0011] As a further preferred embodiment, the anti-collision lining is a conical structure with one end being large and the other end being small, so that the side of the anti-collision lining facing the lens is a chamfered surface, and a tapered cavity is formed between one side of the chamfered surface and the lens;
[0012] The force rod is connected to the small end of the anti-collision lining, and the large end of the anti-collision lining is connected to the inner end surface of the activity space. The force rod pushes the anti-collision lining to compress and shorten the anti-collision lining, and the tapered cavity between its inclined surface and the lens gradually becomes smaller.
[0013] As a further preferred embodiment, the anti-collision liner is a corrugated capsule, and the force rod pushes the anti-collision liner with force to compress and shorten the anti-collision liner, and also compresses and exhausts the volume of the anti-collision liner. The anti-collision liner is connected to the force rod at one end and is also connected to an expansion tube. The expansion tube is arranged in the activity space along the length direction. When the anti-collision liner is compressed and exhausted, the gas is discharged into the expansion tube, so that the expansion tube expands and becomes thicker, and an expansion space is formed between the expansion tube and the lens. The expansion space is also formed between the two expansion tubes and the inner surface of the anti-collision seat. When the expansion tube expands and becomes thicker, the expansion space is filled.
[0014] As a further preference, there are at least two expansion tubes, which are symmetrically arranged on the upper and lower sides of the force rod, and are horizontally extended from one end of the two expansion tubes away from the anti-collision liner and then connected to the inner wall surface of the other end of the activity space.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. When an oncoming car intersects with this car and the rearview mirror on the oncoming car collides with the oncoming side of the mirror cover of this car, the mirror handle will deflect with the mirror cover toward the side of the car body, so that the rearview mirror of this car is protected from force unloading. When the oncoming side of the mirror cover is collided, the anti-collision seat is actually hit first. The anti-collision seat is a rubber seat, so the elasticity of rubber will be used to reduce the degree of impact. In addition, the anti-collision seat will be completely immersed in the groove in the first time due to the collision to reduce and buffer the impact force. After the anti-collision seat realizes the first-level buffering, the impact force is completely transmitted to the entire rearview mirror, so that the mirror cover and the lens complete the above-mentioned deflection action to achieve secondary buffering, which greatly improves the anti-collision ability of the rearview mirror.
[0017] 2. An anti-collision lining is set inside the rearview mirror. When the rearview mirror is hit, the anti-collision lining is compressed, and part of this compression effect is transferred to the lens, forming a buffering and anti-vibration effect on the lens. Another part of the compression effect of the anti-collision lining is also transferred back to the force rod, and then from the force rod to the hinge seat, and then from the hinge seat to the anti-collision seat, so that the collision force hitting the anti-collision seat and the vibration caused by the collision force are further reduced.
[0018] 3. The anti-collision liner is connected to one end of the force rod and is also connected to an expansion tube. The expansion tube is arranged in the activity space along the length direction. When the anti-collision liner is compressed and exhausted, the gas is discharged into the expansion tube, so that the expansion tube expands and thickens, and an expansion space is formed between the expansion tube and the lens. The two expansion tubes also form an expansion space with the inner surface of the anti-collision seat. When the expansion tube expands and thickens, the expansion space is filled and thickened. At this time, the tube wall of the expansion tube is used to contact the inner surface of the lens. There are at least two expansion tubes, and the two expansion tubes are symmetrical on the upper and lower sides of the force rod. The two expansion tubes extend horizontally from one end of the anti-collision liner and are connected to the inner wall surface of the other end of the activity space. The two expansion tubes expand and thicken due to the above factors, and when the tube walls are in contact with the inner surface of the lens, they are used to assist the anti-collision liner in providing a better buffering effect on the inner surface of the lens.

DETAILED DESCRIPTION
[0025] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.
[0026] In one embodiment, Figure 1-Figure 5 As shown:
[0027] The present embodiment provides an automobile anti-collision rearview mirror, comprising a mirror base 1, a mirror handle 2 is hingedly connected to the mirror base 1, a mirror cover 3 is connected to the mirror handle 2, a lens 4 is arranged on the mirror surface side of the mirror cover 3, a notch 5 opposite to the front and rear of the lens 4 is opened on the front side of the mirror cover 3, an anti-collision seat 6 is arranged in the notch 5, a movable space 7 is left between the anti-collision seat 6 and the lens 4, one end of the notch 5 is opened to be close to the mirror handle 2, and the other end of the notch 5 is opened to be close to the side of the mirror cover 3 The slot 5 is opened to the end close to the mirror handle 2 and a rotating shaft 8 is installed on it. One end of the anti-collision seat 6 is installed on the rotating shaft 8, and the other end of the anti-collision seat 6 reaches the side of the slot 5. An inclined surface 12 is provided on the front side of the mirror base 1. The slot 5 is opened on the inclined surface 12. The anti-collision seat 6 is transferred into the slot 5, and the anti-collision seat 6 gradually bulges outward toward the terminal direction of the inclined surface 12. When the convex surface of the anti-collision seat 6 is pressed, the anti-collision seat 6 deflects toward the activity space 7.
[0028] An anti-collision lining 9 is provided in the activity space 7, and the anti-collision lining 9 is sandwiched between the hinged end of the anti-collision seat 6 and the lens 4. When the anti-collision seat 6 deflects toward the activity space 7, the hinged seat 10 is used to push the force rod 11, and the other end of the force rod 11 squeezes the anti-collision lining 9, and the anti-collision lining 9 squeezes the thickness direction of the lens 4 to perform a buffering action;
[0029] An articulated seat 10 is provided at the middle portion of the inner surface of the anti-collision seat 6, to which a force rod 11 is connected, and the other end of the force rod 11 is connected to the end of the anti-collision liner 9 along the length direction of the activity space 7. When the anti-collision seat 6 is deflected toward the activity space 7, the articulated seat 10 is also used to drive the force rod 11 to deflect toward the end of the anti-collision liner 9, and force is applied from the end to the anti-collision liner 9, so that the anti-collision liner 9 squeezes the buffering action toward the length direction of the lens 4.
[0030] When the oncoming car intersects with the vehicle and the rearview mirror on the oncoming car collides with the oncoming side of the mirror cover 3 of the vehicle, the mirror handle 2 will deflect with the mirror cover 3 toward the side of the vehicle body, so that the rearview mirror of the vehicle is protected from force unloading. When the oncoming side of the mirror cover 3 is hit, the anti-collision seat 6 is actually hit first. The anti-collision seat 6 is a rubber seat, so the impact degree will be reduced by rubber elasticity. In addition, the anti-collision seat 6 will be completely immersed in the groove 5 in the first time due to the collision to reduce and buffer the impact force. After the anti-collision seat 6 realizes the first-level buffering, the impact force is completely transmitted to the entire rearview mirror, so that the mirror cover 3 and the lens 4 complete the above-mentioned deflection action to achieve secondary buffering, thereby greatly improving the anti-collision ability of the rearview mirror.
[0031] When the anti-collision seat 6 is immersed in the slot 5 and rotates with the rotating shaft 8 as the rotation center, it will also push the hinge seat 10 to deflect toward the back side of the lens 4, and the hinge seat 10 will push the lever 11. Since the lever 11 is limited in the activity space 7 between the anti-collision seat 6 and the lens 4, when the anti-collision seat 6 deflects toward the direction of the lens 4, the lever 11 will be pushed by the lever 11, and the other end of the lever 11 will squeeze the anti-collision lining 9. The anti-collision lining 9 is a rubber corrugated seat, so the anti-collision lining 9 will be compressed, and part of this compression effect will be transferred to the lens 4, forming a buffering and anti-vibration effect on the lens 4. Another part of the compression effect of the anti-collision lining 9 will also be reversely transferred to the lever 11, and then reversely transferred to the hinge seat 10 by the lever 11, and then reversely transferred to the anti-collision seat 6 by the hinge seat 10, so that the collision force hitting the anti-collision seat 6 and the vibration degree generated by the collision force are further reduced.
[0032] A circle of anti-drop rubber 13 is arranged on the mirror surface end of the mirror cover 3 to prevent the lens 4 from falling forward, the mirror surface side of the lens 4 is restricted within the anti-drop rubber 13, and the back side of the lens 4 is restricted by the hinge seat 10 and the anti-collision lining 9. It can be seen that one side of the lens 4 is restricted by the anti-drop rubber 13, and the other side is restricted by the hinge seat 10 and the anti-collision lining 9. The lens 4 is not completely fixed in the mirror cover 3 in a rigid installation manner. In this way, when the front surface of the mirror cover 3 collides, the lens 4 uses the buffering effect of the anti-collision lining 9 to achieve vibration reduction on the inner side, and uses the anti-drop rubber 13 to achieve vibration reduction on the outer side.
[0033] The anti-collision liner 9 is a conical structure with one end large and the other end small, so that the side of the anti-collision liner 9 facing the lens 4 is a chamfered surface 14, and a tapered cavity 15 is formed between one side of the chamfered surface 14 and the lens 4; the force rod 11 is connected to the small end of the anti-collision liner 9, and the large end of the anti-collision liner 9 is connected to the inner end surface of the activity space 7. The force rod 11 pushes the anti-collision liner 9 with force to compress and shorten the anti-collision liner 9, and at the same time, the tapered cavity 15 between the chamfered surface 14 and the lens 4 gradually becomes smaller. When the anti-collision liner 9 is pushed and compressed by the force rod 11, its tapered cavity 15 becomes smaller, that is, the chamfered surface 14 side gradually approaches the lens 4 according to the tapered cavity 15. The tapered cavity 15 is used as the movement space for the anti-collision liner 9 to press against the lens 4, which not only increases the compression stroke of the anti-collision liner 9 in the length direction and further improves the buffering and vibration reduction effect, but also as the compression degree of the anti-collision liner 9 increases, the chamfered surface 14 side gradually approaches the inner surface of the lens 4, so that the buffering time acting on the inner surface of the lens 4 is prolonged, and the protective effect on the lens 4 is further improved. Therefore, the lens 4 does not need to be made of expensive or complex materials.
[0034] In another embodiment, if Figures 3 to 5As shown, the anti-collision liner 9 is a corrugated capsule. The force rod 11 pushes the anti-collision liner 9 to compress and shorten the anti-collision liner 9. In addition to better applying the compression buffering effect of the anti-collision liner 9 to the lens 4, the volume of the anti-collision liner 9 is compressed and reduced, and the gas is gradually exhausted to the outside. The end of the anti-collision liner 9 connected to the force rod 11 is also connected to an expansion tube 16. The expansion tube 16 is arranged in the activity space 7 along the length direction. When the anti-collision liner 9 is compressed and exhausted, the gas is discharged into the expansion tube 16, so that the expansion tube 16 expands. The expansion tube 16 expands and thickens, and an expansion space 17 is formed between the expansion tube 16 and the lens 4. The two expansion tubes 16 also form an expansion space 17 with the inner surface of the anti-collision seat 6. When the expansion tube 16 expands and thickens, the expansion space 17 is filled and thickened. At this time, the tube wall of the expansion tube 16 is in contact with the inner surface of the lens 4. There are at least two expansion tubes 16, and the two expansion tubes 16 are symmetrical on the upper and lower sides of the force rod 11. The two expansion tubes 16 extend horizontally from one end of the anti-collision liner 9 and are connected to the inner wall surface of the other end of the activity space 7. The two expansion tubes 16 expand and become thicker due to the above factors, and when the tube walls are in contact with the inner surface of the lens 4, they are used to assist the anti-collision lining 9 in providing a better buffering effect on the inner surface of the lens 4. Under normal conditions (when the rearview mirror is not hit), the rearview mirror is extended on both sides of the vehicle body. At this time, the anti-collision seat 6 protrudes on the back of the mirror cover 3 because it has not been hit, that is, the anti-collision seat 6 is not rotated in the groove 5 at this time, and the hinge seat 10 does not deflect into the activity space 7 with the anti-collision seat 6, the force rod 11 does not push the anti-collision lining 9, and the anti-collision lining 9 is not compressed. Similarly, the anti-collision lining 9 is not compressed and exhausted. Instead, the anti-collision lining 9 elastically lengthens and uses the one-way valve at the bottom to inhale air inward to maintain the bulging state. The air pressure in the expansion tube 16 is re-absorbed into the anti-collision lining 9, only The inner end of the articulated seat 10 and the terminal part of the chamfered surface 14 of the anti-collision lining 9 limit the inner surface of the lens 4, and the expansion tube 16 becomes thinner at this time, and its tube wall leaves the inner surface of the lens 4, preventing the expansion tube 16 from maintaining contact with the inner surface of the lens 4 for a long time, causing the expansion tube 16 to adhere to the inner surface of the lens 4 due to the rubber properties. For example, when the expansion tube 16 is plastically deformed due to high temperature in summer, it will be plastically adhered to the inner surface of the lens 4. Only when the rearview mirror suddenly experiences the above situation, and the anti-collision seat 6 deflects inward with the articulated seat 10, the articulated seat 10 pushes the force rod 11, and the force rod 11 pushes the anti-collision lining 9 to inject air into the expansion tube 16, the expansion tube 16 is inflated to become thicker and forms a buffering contact with the inner surface of the lens 4 in order to provide a buffering effect to the inner surface of the lens 4.
