[0024] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.
[0025] Reference will be made below Figure 1 to describe the seal 100 according to an embodiment of the present utility model.
[0026] As Figure 1 shown, the seal 100 according to an embodiment of the present utility model includes: a first body 1 and a second body 2. The cross-section of the first body 1 is annular. The second body 2 is disposed on the first body 1. Along the axial direction of the seal 100, the second body 2 and the first body 1 are arranged. The second body 2 includes a plurality of arc segments 21. Among the plurality of arc segments 21, at least one arc segment 21 protrudes toward the radially outer side of the seal 100, and at least one arc segment 21 protrudes toward the radially inner side of the seal 100.
[0027] Among them, the cross-section of the first body 1 is annular, that is to say, the first body 1 can be constructed as an annular member. The second body 2 is disposed on the first body 1. Along the axial direction of the seal 100, the first body 1 and the second body 2 are arranged. The second body 2 includes a plurality of arc segments 21. As some embodiments of the present application, the plurality of arc segments 21 can be arranged at intervals. As other embodiments of the present application, the plurality of arc segments 21 can be connected, that is to say, the plurality of arc segments 21 are connected in sequence.
[0028] As some embodiments of the present application, both the first body 1 and the second body 2 can be made of rubber material. As some embodiments of the present application, both the first body 1 and the second body 2 can be made of resin material.
[0029] Among the plurality of arc segments 21, at least one arc segment 21 protrudes toward the radially outer side of the seal 100, and at least one arc segment 21 protrudes toward the radially inner side of the seal 100. As a specific embodiment of the present application, as Figure 1As shown in the figure, the second main body 2 is composed of 48 arc segments 21. Among the 48 arc segments 21, 24 arc segments 21 protrude towards the radially outer side of the seal 100, and 24 arc segments 21 protrude towards the radially inner side of the seal 100. And, along the circumferential direction of the seal 100, on both sides of each arc segment 21 protruding towards the radially outer side of the seal 100 are arc segments 21 protruding towards the radially inner side of the seal 100, so that a plurality of arc segments 21 can form a wavy second main body 2. When the temperature is relatively low, a plurality of arc segments 21 can offset the contraction force from each other to reduce the deformation amount of the second main body 2. When the temperature is relatively high, the resultant force of the expansion force will act along the protruding parts of the arc segments 21, so that the sealing effect of the seal 100 is better. And, the compression deformation amounts of the first main body 1 and the second main body 2 can be coupled, so that the compression deformation amounts of the first main body 1 and the second main body 2 are reasonable, and thus a better sealing effect can be achieved.
[0030] In the above embodiment, by providing the second main body 2 including a plurality of arc segments 21, and making at least one arc segment 21 protrude towards the radially outer side of the seal 100 and at least one arc segment 21 protrude towards the radially inner side of the seal 100, the compression amount of the seal 100 can be more easily controlled, and the deformation amount of the second main body 2 in this structural form is less affected by temperature, thereby improving the sealing performance of the seal 100.
[0031] In some embodiments of the present utility model, as Figure 1 shown, along the radial direction of the seal 100, the size of the arc segment 21 is smaller than the size of the first main body 1, and the radial direction of the seal 100 is perpendicular to the axial direction of the seal 100.
[0032] Among them, since along the radial direction of the seal 100, the size of the arc segment 21 is smaller than the size of the first main body 1, the arc segment 21 can be more easily elastically deformed, so as to more easily control the deformation amount of the second main body 2, so that the seal 100 can better play a sealing role.
[0033] In some embodiments of the present utility model, as Figure 1 shown, a plurality of arc segments 21 include: a plurality of first arc segments 211 and a plurality of second arc segments 212. The plurality of first arc segments 211 and the plurality of second arc segments 212 are alternately arranged along the circumferential direction of the seal 100. The first arc segment 211 protrudes towards the radially outer side of the seal 100, and the second arc segment 212 protrudes towards the radially inner side of the seal 100.
[0034] Among them, a plurality of first arc segments 211 and a plurality of second arc segments 212 are arranged alternately along the circumferential direction of the seal 100. That is to say, there is a second arc segment 212 between two closest first arc segments 211, and there is a first arc segment 211 between two closest second arc segments 212. The first arc segment 211 protrudes towards the radially outer side of the seal 100, and the second arc segment 212 protrudes towards the radially inner side of the seal 100. The plurality of first arc segments 211 and the plurality of second arc segments 212 form a wavy annular second body 2. The wavy annular second body 2 can make the compression amount of the seal 100 easier to control, and the wavy annular second body 2 is less affected by temperature, which can improve the sealing performance of the seal 100.
[0035] As a specific embodiment of the present application, the first arc segment 211 and the second arc segment 212 can be directly connected. For example, the first arc segment 211 has opposite ends, one end of the first arc segment 211 is connected to a second arc segment 212, and the other end of the first arc segment 211 is connected to another second arc segment 212.
[0036] As a specific embodiment of the present application, the first arc segment 211 and the second arc segment 212 can be connected by a connecting sub-segment. That is to say, the connecting sub-segment has opposite ends, one end of the connecting sub-segment is connected to a first arc segment 211, and the other end of the connecting sub-segment is connected to a second arc segment 212.
[0037] In some embodiments of the present utility model, as Figure 1 shown, along the circumferential direction of the seal 100, second arc segments 212 are provided at both ends of each first arc segment 211, and both ends of the first arc segment 211 are respectively connected to the ends of adjacent second arc segments 212.
[0038] Among them, along the circumferential direction of the seal 100, the first arc segment 211 and the second arc segment 212 can be directly connected. Specifically, the first arc segment 211 has opposite ends, one end of the first arc segment 211 is connected to the end of a second arc segment 212, and the other end of the first arc segment 211 is connected to the end of another second arc segment 212. In other words, the second arc segment 212 has opposite ends, one end of the second arc segment 212 is connected to the end of a first arc segment 211, and the other end of the second arc segment 212 is connected to the end of another first arc segment 211. Such a setting can make the second body 2 constructed into a wavy shape. The wavy annular second body 2 can make the compression amount of the seal 100 easier to control, and the wavy second body 2 is less affected by temperature, which can improve the sealing performance of the seal 100.
[0039] In some embodiments of the present utility model, asFigure 1 As shown, the second main body 2 further includes: a plurality of connecting segments 213. Along the circumferential direction of the seal 100, each first arc segment 211 is connected to an adjacent second arc segment 212 through a connecting segment 213.
[0040] Among them, adjacent first arc segments 211 and second arc segments 212 can be connected through a connecting segment 213. Specifically, along the circumferential direction of the seal 100, each first arc segment 211 is connected to an adjacent second arc segment 212 through a connecting segment 213. That is to say, both ends of each first arc segment 211 are respectively connected to two adjacent second arc segments 212 through two connecting segments 213. By providing the connecting segment 213, adjacent first arc segments 211 and second arc segments 212 can be connected together to construct the second main body 2 into an annular second main body 2, so that the deformation amount of the second main body 2 can be more easily controlled. Moreover, such a setting facilitates the processing of the second main body 2, thereby reducing the manufacturing difficulty of the seal 100.
[0041] In some embodiments of the present utility model, as Figure 1 shown, the connecting segment 213 is a straight line segment, or the connecting segment 213 is an arc segment.
[0042] As some embodiments of the present application, the connecting segment 213 can be a straight line segment. The straight line segment is convenient for processing. By constructing the connecting segment 213 as a straight line segment, the manufacturing difficulty of the seal 100 can be reduced.
[0043] As some embodiments of the present application, the connecting segment 213 can be an arc segment. By constructing the connecting segment 213 as an arc segment, multiple arc segments 21 and the arc segment can cooperate. When the temperature is relatively low, the contraction forces can effectively cancel each other out, and the deformation amount of the second main body 2 can be effectively reduced. When the temperature is relatively high, the resultant force of the expansion forces will be along the convex part of the arc segment 21, so that the sealing effect of the seal 100 is better.
[0044] In some embodiments of the present utility model, as Figure 1 shown, partial outer edges of a plurality of first arc segments 211 are coplanar with the outer edge of the first main body 1, and / or, partial inner edges of a plurality of second arc segments 212 are coplanar with the inner edge of the first main body 1.
[0045] Among them, partial outer edges of a plurality of first arc segments 211 are coplanar with the outer edge of the first main body 1, or partial inner edges of a plurality of second arc segments 212 are coplanar with the inner edge of the first main body 1, or partial outer edges of a plurality of first arc segments 211 can be coplanar with the outer edge of the first main body 1, and partial inner edges of a plurality of second arc segments 212 are coplanar with the inner edge of the first main body 1.
[0046] By making the partial outer edges of multiple first arc segments 211 coplanar with the outer edge of the first main body 1, and / or making the partial inner edges of multiple second arc segments 212 coplanar with the inner edge of the first main body 1, the curvature of the arc segment 21 can be made larger, so that the second main body 2 can better play a sealing role, and the sealing performance of the seal 100 can be improved.
[0047] In some embodiments of the present utility model, as Figure 1 shown, the arc segment 21 and the first main body 1 jointly define an oil storage groove 3.
[0048] Among them, the arc segment 21 and the first main body 1 can define an oil storage groove 3, and the oil storage groove 3 is used to store lubricating oil. The lubricating oil can reduce the friction between the seal 100 and the connected components, so as to reduce the energy consumption of the whole system. At the same time, the lubricating oil can improve the sealing performance of the seal 100. The oil storage groove 3 jointly defined by the arc segment 21 and the first main body 1 is beneficial to storing more lubricating oil and can reduce the loss of lubricating oil, so that the seal 100 can be fully lubricated.
[0049] In some embodiments of the present utility model, as Figure 1 shown, the first main body 1 and the second main body 2 are integrally formed.
[0050] Among them, the first main body 1 and the second main body 2 are integrally formed. That is to say, the first main body 1 and the second main body 2 can be an integrally formed part. The integrally formed part has good structural strength. By integrally forming the first main body 1 and the second main body 2, the connection between the first main body 1 and the second main body 2 can be made closer, the probability of fracture at the connection between the first main body 1 and the second main body 2 can be reduced, and the service life of the seal 100 can be extended.
[0051] The vehicle according to the embodiment of the present utility model includes the seal 100 of the above embodiment. By providing a second main body 2 including a plurality of arc segments 21, and making at least one arc segment 21 protrude toward the radial outside of the seal 100 and at least one arc segment 21 protrude toward the radial inside of the seal 100, the compression amount of the seal 100 can be more easily controlled, and the deformation amount of the second main body 2 in this structural form is less affected by temperature, thereby improving the sealing performance of the seal 100.
