Description
Technical Field
[0001] The utility model belongs to the technical field of automobile accessories, and particularly relates to a gasket and a folder with the gasket. Background Art
[0002] As cars continue to be updated, electric rearview mirrors have become standard components for most high-end models. However, in actual use, it is found that as the number of times the electric rearview mirrors are unfolded and folded increases, the frequency of abnormal noises generated by the electric rearview mirrors is also increasing.
[0003] Since the folder of the electric rearview mirror is composed of a main shaft, a housing, a spring, a gear, a base and other parts sleeved on the outside of the main shaft, and after assembly, it is necessary to ensure that the two ends of the spring can firmly contact between the shaft cap of the main shaft and the gear. On this basis, after inspection, it was found that the main reason for the abnormal noise was that the friction between the gasket set inside the gear and the spring pressed on the end face of the gasket was too large. Therefore, at the moment when the electric rearview mirror was unfolded and folded, the gasket and the spring in the gear were easily slightly moved, causing the spring to be subjected to circumferential force, thereby generating abnormal noise.

[0047] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.
[0048] The most critical concept of the utility model is that by arranging corresponding first oil storage grooves on the two end surfaces of the gasket body, the gasket body has the ability to store lubricating substances for a long time, so that a smooth film can be formed on the two end surfaces of the gasket body, thereby effectively reducing the friction between the gasket body and other components, so as to achieve the effect of eliminating abnormal noise.
[0049] Please refer to Figures 1 to 7 The gasket provided by the utility model includes a gasket body 1;
[0050] The gasket body 1 is an annular structure;
[0051] First oil storage grooves 11 are provided on both end surfaces of the gasket body 1 .
[0052] From the above description, it can be seen that the beneficial effect of the utility model is: to provide a gasket, by arranging corresponding first oil storage grooves 11 on the two end faces of the gasket body 1, the gasket body 1 has the ability to store lubricating substances for a long time. Compared with the existing gaskets, in actual use engineering, a long-lasting smooth film is formed on the two end faces of the gasket body 1, thereby effectively reducing the friction between the gasket body 1 and other components, and avoiding abnormal noise when the gasket body 1 and other components move relative to each other.
[0053] Furthermore, the edges of the inner and outer circumferential surfaces of the gasket body 1 are both provided with rounded corner structures.
[0054] As can be seen from the above description, this design makes the edge of the gasket body 1 more rounded, avoiding the edge being too sharp, which would cause other parts to make sharp and harsh noises when they come into contact with the gasket body 1.
[0055] Furthermore, at least two first oil storage grooves 11 are provided on both end surfaces of the gasket body 1;
[0056] With the axis of the gasket body 1 as the rotation axis, the first oil storage grooves 11 are evenly distributed on the end surface of the gasket body 1 .
[0057] Furthermore, the first oil storage tank 11 is a waist-shaped tank.
[0058] From the above description, it can be seen that the first oil storage groove 11 evenly distributed on the end surface of the gasket body 1 can ensure that when the gasket body 1 contacts other parts, each position of the contact surface can contact the lubricating substance, thereby ensuring the smoothness of the contact surface, and the waist-shaped first oil storage groove 11 can ensure that the groove structure is simple while storing as much lubricating substance as possible inside the first oil storage groove 11, thereby ensuring that the end surface of the gasket body 1 is smooth for a long time.
[0059] The utility model also provides a folder, comprising a housing 2, a base 3, a rotating shaft 4, an elastic element 5, a gear 6 and any one of the above-mentioned gasket bodies 1;
[0060] Along the axial direction of the rotating shaft 4, the outer side of the rotating shaft 4 is sleeved with an elastic element 5, a gasket body 1, a gear 6 and a base 3 in sequence;
[0061] The elastic element 5, the gasket body 1 and the gear 6 are all located in the housing 2;
[0062] One end of the rotating shaft 4 is provided with a shaft cap 42;
[0063] The gasket body 1 is arranged between the elastic element 5 and the gear 6;
[0064] Two ends of the elastic element 5 are in contact with the end surface of the gasket body 1 and the inner wall of the housing 2 respectively.
[0065] From the above description, it can be seen that by arranging the gasket body 1 inside the folder, the end face of the gasket body 1 and the elastic element 5 can be prevented from having slight relative movement due to excessive friction and causing abnormal noise when the folder is unfolded and folded.
[0066] Furthermore, the elastic element 5 can be any commercially available elastic device, such as a coil spring, a wave spring, etc.
[0067] Specifically, the structure of the shell 2 and the base 3 can refer to the shell and base of a folding drive device disclosed in the Chinese invention patent with application number CN202110181219.6.
[0068] Furthermore, the above-mentioned folder further includes a transition gasket 7;
[0069] The transition washer 7 is sleeved on the outer side of the rotating shaft 4;
[0070] The transition gasket 7 is located between the elastic element 5 and the gasket body 1;
[0071] Two ends of the transition gasket 7 are in contact with the end surface of the elastic element 5 and the end surface of the gasket body 1 respectively.
[0072] Furthermore, the outer surface of the rotating shaft 4 is provided with at least one anti-rotation straight surface 41;
[0073] The plane where the anti-rotation straight surface 41 is located is parallel to the axis of the rotating shaft 4;
[0074] An anti-rotation block 71 is provided on the inner circumferential surface of the transition gasket 7;
[0075] Specifically, the anti-rotation block 71 and the transition washer 7 are an integrated structure;
[0076] The anti-rotation block 71 includes an anti-rotation surface;
[0077] When the transition washer 7 and the rotating shaft 4 are sleeved together, the anti-rotation surface of the anti-rotation block 71 and the anti-rotation straight surface 41 are parallel to and in contact with each other.
[0078] It can be seen from the above description that by respectively arranging an anti-rotation block 71 and an anti-rotation straight surface 41 on the transition gasket 7 and the rotating shaft 4, relative rotation can be prevented between the transition gasket 7 and the rotating shaft 4 during the operation of the folder, thereby avoiding the situation where the transition gasket 7 and the elastic element 5 move relative to each other due to the gasket body 1 driving the transition gasket 7 to rotate, thereby avoiding the situation where the transition gasket 7 and the elastic element 5 move relative to each other and then emit abnormal noise. The transition gasket 7 can also indirectly improve the damping of the folder, that is, to ensure that when the folder is in a fully unfolded or fully folded state, when the external force is less than the damping of the folder, the folder can maintain its original state, thereby improving the stability of the folder.
[0079] Furthermore, second oil storage grooves 72 are provided on both end surfaces of the transition gasket 7 .
[0080] Furthermore, at least two second oil storage grooves 72 are provided on both end surfaces of the transition gasket 7;
[0081] With the axis of the transition gasket 7 as the rotation axis, the second oil storage grooves 72 are evenly distributed on the end surface of the transition gasket 7 .
[0082] Furthermore, the second oil storage tank 72 is a waist-shaped tank.
[0083] From the above description, it can be seen that by setting a second oil storage groove 72 on the end face of the transition gasket 7 and adding lubricating material in the second oil storage groove 72, the friction between the transition gasket 7 and the elastic element 5 and the gasket body 1 can be further reduced, thereby making the effect of eliminating abnormal noise more obvious.
[0084] The gasket of the utility model can be arranged on equipment that needs to perform axis rotation, and is particularly suitable for a folder of an electric rearview mirror of an automobile.
[0085] Please refer to Figures 1 to 7 , Embodiment 1 of the present utility model is:
[0086] A gasket comprises a gasket body 1; the gasket body 1 is an annular structure; twelve first oil storage grooves 11 are provided on both end surfaces of the gasket body 1; rounded structures are provided at the edges of the inner circular surface and the outer circular surface of the gasket body 1; with the axis of the gasket body 1 as the rotation axis, the first oil storage grooves 11 are evenly distributed on the end surface of the gasket body 1; the first oil storage grooves 11 are waist-shaped grooves; the material of the gasket body 1 is plastic.
[0087] Referring to Figures 1 to 3, the second embodiment of the present invention is as follows:
[0088] A folder, comprising a shell 2, a base 3, a rotating shaft 4, an elastic element 5, a transition gasket 7, a gear 6 and a gasket body 1; the shell 2 and the base 3 are mutually buckled and form a storage space, and the shell 2 and the base 3 are both sleeved on the outside of the rotating shaft 4; the elastic element 5, the transition gasket 7, the gasket body 1 and the gear 6 are all located in the storage space and are sleeved on the outside of the rotating shaft 4 in the axial direction of the rotating shaft 4 in sequence; the two ends of the transition gasket 7 are respectively in conflict with the end face of the elastic element 5 and the end face of the gasket body 1; the other end of the elastic element 5 is in conflict with the inner wall of the shell 2 conflict with each other; at least one anti-rotation straight surface 41 is provided on the outer surface of the rotating shaft 4; the plane where the anti-rotation straight surface 41 is located is parallel to the axis of the rotating shaft 4; an anti-rotation block 71 is provided on the inner circular surface of the transition gasket 7; when the transition gasket 7 and the rotating shaft 4 are mutually sleeved, the anti-rotation surface of the anti-rotation block 71 is parallel to and conflicts with the anti-rotation straight surface 41; sixteen second oil storage grooves 72 are provided on both end surfaces of the transition gasket 7; with the axis of the transition gasket 7 as the rotation axis, the second oil storage grooves 72 are evenly distributed on the end surface of the transition gasket 7; the second oil storage grooves 72 are waist-shaped grooves.
[0089] The difference between the third embodiment of the present invention and the first embodiment is that:
[0090] The material of the gasket body 1 in this embodiment is Teflon. Since Teflon itself has excellent lubricity, it can still achieve the effect of reducing the friction between the gasket body 1 and other components without the need for a coating lubricant, thereby eliminating the first oil storage tank 11 to simplify the production steps and improve production efficiency.
[0091] The working principle of the utility model is as follows: before use, corresponding lubricating substances are added to the first oil storage tank 11 and the second oil storage tank 72 respectively, and the elastic element 5, the transition gasket 7, the gasket body 1 and the gear 6 are sequentially sleeved on the outer side of the rotating shaft 4; then, the rotating shaft 4 is sequentially passed through the shell 2 and the base 3, and when the shaft cap 42 of the rotating shaft 4 abuts against the shell 2, the rotating shaft 4 is fixed to the base 3 by any fastener, at this time, the elastic element 5, the transition gasket 7, the gasket body 1 and the gear 6 are just located inside the shell 2, and under the action of the elastic element 5, the transition gasket 7, the gasket body 1 and the gear 6 are firmly abutted together.
[0092] When the folder is unfolded or folded, due to the limiting effect between the anti-rotation straight surface 41 and the anti-rotation block 71, the transition gasket 7, the rotating shaft 4 and the elastic element 5 can be relatively still. At the same time, because lubricating material is filled between the gasket body 1 and the transition gasket 7, even if the gasket body 1 and the transition gasket 7 can rotate relatively, no abnormal sound will be generated due to the extremely small friction.
[0093] To sum up, the utility model provides a gasket with a simple structure and low cost; by arranging corresponding first oil storage grooves on the two end surfaces of the gasket body, the gasket body has the ability to store lubricating substances for a long time. Compared with the existing gaskets, in actual use projects, a long-lasting smooth film is formed on the two end surfaces of the gasket body, thereby effectively reducing the friction between the gasket body and other components, and effectively solving the problem of the existing folder being prone to abnormal noise during movement due to the excessive friction between the gasket body and other components at the moment of unfolding and folding.
[0094] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
