[0070] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0071] To achieve the above objectives, in accordance with the first aspect of this application, referring to Figures 1 to 3As shown, a leak-proof component 100 is provided, which can be used to seal the guide groove 210b. In a specific embodiment, the guide groove 210b mentioned herein is formed, for example, on a transmission mechanism, to guide one part of the transmission mechanism to move along a preset direction of movement, so that the two parts of the transmission mechanism form a follower connection.

[0072] The leak-proof component 100 includes a body 110. The body 110 has a body space 110c extending along a first direction X1, which can be used, for example, to accommodate a portion of the aforementioned transmission mechanism components.

[0073] The body 110 also has a clearance channel 110a extending at least in a direction inclined to the first direction X1; the clearance channel 110a passes through the body 110 to connect the body space 110c with the external space, the external space referred to here being the spatial region outside the body space 110c separated by the walls of the body 110, which is connected to the body space 110c through the clearance channel 110a. The extension direction of the clearance channel 110a can be adapted to the guide groove 210b, so that when the component moves relative to the guide groove 210b, the clearance channel 110a avoids the component, thereby allowing the component to move normally.

[0074] In this way, by forming a clearance channel 110a on the body 110, the clearance channel 110a can be configured to match the shape of the guide groove 210b of the transmission mechanism, allowing the components to pass through the clearance channel 110a normally and enter the guide groove 210b. The extension direction of the clearance channel 110a is adapted to the usage scenario where the components of the transmission mechanism move relative to the body 110 under the guidance of the guide groove 210b, without affecting the normal guidance of the components by the guide groove 210b. At the same time, it forms a certain sealing effect on the guide groove 210b, so that when the components move in the guide groove 210b, only lubricant needs to be filled in the guide groove 210b. The amount of lubricant used as a reserve filled in the space outside the guide groove 210b is small. Therefore, the amount of lubricant required by the transmission mechanism that integrates the anti-leakage component 100 can be reduced. The anti-leakage component 100 provided in this application specifically forms a seal to prevent leakage in the guide groove 210b, making the anti-leakage component 100 suitable for use in transmission mechanisms with guide groove 210b.

[0075] Specifically, the lubricant can be, for example, lubricating oil or grease, which can be selected by those skilled in the art according to actual needs.

[0076] As a specific example, in an optional implementation, at least one end of the avoidance channel 110a is closed along its extension direction. For example, both ends of the avoidance channel 110a are closed along its extension direction, that is, the avoidance channel 110a does not penetrate the body 110 along its extension direction. This solution can reduce the negative impact of opening the avoidance channel 110a on the structural strength of the body 110, that is, ensure that the leak-proof component 100 itself has sufficient structural strength.

[0077] This application does not specifically limit the extension direction of the avoidance channel 110a and the guide groove 210b, as long as the guide groove 210b can guide the movement path of the portion of the transmission mechanism embedded in the guide groove 210b. As an example, in some embodiments, at least a section of the avoidance channel 110a extends in a spiral shape, for example. Correspondingly, the guide groove 210b also extends in a spiral direction. When the component with the spiral guide groove 210b rotates, the component embedded in the guide groove 210b can slide relative to the body 110. Since the body 110 forms the avoidance channel 110a, it avoids interference with the relative movement between the two components.

[0078] In some embodiments, the body 110 is provided with a plurality of clearance channels 110a. The plurality of clearance channels 110a are circumferentially distributed on the body 110 around a central axis L1. Correspondingly, a plurality of guide grooves 210b can be configured on the transmission mechanism to increase the number of connection points and contact area between two relatively sliding parts of the transmission mechanism, thereby ensuring the structural strength of the transmission mechanism. As an exemplary illustration of a specific solution, the body is, for example, cylindrical, wherein the clearance channels 110a pass through the cylindrical surface of the cylindrical body, and the central axis L1 is the centerline of the cylindrical body; more specifically, the central axis L1 may be parallel to the first direction X1.

[0079] In some embodiments, the body space 110c may be configured to accommodate one of two relatively sliding components of the transmission mechanism, and may also be used to reduce the material used in the leak-proof component 100 to lower its manufacturing cost. At least one end of the body space 110c communicates with the outside along a first direction X1, for example, the body space extends through the body 110 along the first direction X1, allowing a portion of the transmission mechanism located in the body space 110c to extend out of the body space 110c, facilitating connection of this portion of the structure to a drive element or other driven equipment.

[0080] According to the second aspect of this application, referring to Figures 2 to 3As shown, a transmission assembly 200 is provided, including the aforementioned leak-proof member 100 and guide member 210. The body 110 of the leak-proof member 100 and the guide member 210 are mechanically connected. Specifically, the guide member 210 has a guide groove 210b, and the body 110 and the guide member 210 are nested together so that the guide groove 210b communicates with the clearance channel 110a.

[0081] It is understood that the guide member 210 is the component forming the guide groove 210b in the transmission mechanism mentioned above, wherein the clearance channel 110a communicates with the guide groove 210b so that the transmission assembly 200 can be combined with other components to form the aforementioned transmission mechanism, so that when the guide member 210 moves, it drives other components to move relative to the body 110. Referring to the foregoing description, the transmission assembly 200 has all the beneficial effects of the aforementioned leak-proof component 100, which will not be described further in this application.

[0082] In some embodiments, the guide groove 210b extends in a helical direction. Specifically, the guide groove 210b extends helically on the guide member 210 about the rotation axis L2, so that when the guide member 210 rotates, it causes the follower member 220 to slide relative to the guide member 210. In a specific embodiment, the rotation axis L2 is, for example, collinear with the central axis L1 described above.

[0083] In some embodiments, the edge 110b of the clearance channel extends beyond the edge 210c of the guide groove to stop at the edge 210c of the guide groove. Thus, the edge 110b of the clearance channel can block the lubricant within the guide groove 210b, preventing at least some of the lubricant from leaking outside the guide groove 210b.

[0084] By adopting the above solution, by forming a clearance channel 110a on the body 110 that matches the guide groove 210b, components can pass normally through the clearance channel 110a and enter the guide groove 210b without affecting the normal guiding of component movement by the guide groove 210b. Furthermore, the edge 110b of the clearance channel blocks the edge 210c of the guide groove, preventing lubricant leakage from the guide groove 210b when the component moves within it, thus ensuring effective lubrication of the guide groove 210b. Moreover, only lubricant needs to be filled into the guide groove 210b during use; there is no need to fill the space outside the guide groove 210b with additional lubricant to replenish any leaks, or to reduce the amount of lubricant required. Therefore, the lubricant requirement of the transmission mechanism integrating the leak-proof component 100 can be reduced.

[0085] In some embodiments, the two opposite edges of the clearance channel 110a extend beyond the edge 210c of the guide groove. This allows the lubricant carried by the component within the guide groove 210b during movement to be adequately blocked by the opposite edges of the clearance channel 110a, further reducing lubricant leakage and creating a seal-like effect on the guide groove 210b to reduce or prevent lubricant leakage (for ease of explanation, this effect of reducing or preventing lubricant leakage will be described hereinafter as a "sealing effect").

[0086] Considering that in the transmission mechanism, the portion inserted into the guide groove 210b needs to contact the wall surface forming the guide groove 210b to guide the movement direction, while another portion of the transmission mechanism is located outside the guide groove 210b to drive other components, or the portion outside the guide groove 210b is driven by a driving component to move the entity forming the guide groove 210b, in a specific design, the ratio of the length of the edge 110b of the clearance channel extending beyond the edge 210c of the guide groove to the width of the guide groove 210b can be further limited to a range of 0.17 to 0.31. This ensures that while guaranteeing the sealing effect of the edge 110b of the clearance channel on the guide groove 210b, sufficient structural strength is maintained between the portion of the transmission mechanism inserted into the guide groove 210b and the entity adjacent to that portion.

[0087] In a more specific scheme, for example, the length of the edge 110b of the clearance channel extending beyond the edge 210c of the guide groove is in the range of 4 to 6.5 mm. That is, in the extension direction of the clearance channel 110a, the length of the part of the edge 110b of the clearance channel extending beyond the guide groove 210b at each location is relatively uniform, ensuring a stable sealing effect on the guide groove 210b.

[0088] As an example of the formation of the clearance channel 110a and the guide groove 210b, at least a section of the clearance channel 110a and / or at least a section of the guide groove 210b extends in a spiral direction. Thus, when the guide member 210 is rotated by a driving member, the component embedded in the guide groove 210b can slide relative to the guide member, thereby realizing the transmission function.

[0089] In some embodiments, at least one end of the clearance channel 110a along its extension direction is closed, and / or at least one end of the guide groove 210b along its extension direction is closed, so as to reduce the possibility of lubricant leaking from the ends of the clearance channel 110a and / or the guide groove 210b.

[0090] As one specific implementation, the guide 210 is integrally formed with the body 110.

[0091] Alternatively, the guide 210 can be integrated into a single unit by being fixedly connected to the body 110. As a specific example, in some embodiments, the guide 210 includes a receiving cavity 210a. The receiving cavity 210a is used to receive the body 110, meaning the body 110 can be fixed inside the guide 210. The receiving cavity 210a formed by the guide 210 is, for example, a cylindrical chamber to match the shape of the body 110, facilitating the integrated installation of the body 110. A guide groove 210b is recessed into the inner wall of the receiving cavity 210a formed by the guide 210. By providing the receiving cavity 210a to install the leak-proof component 100, the space occupied by the guide 210 and the leak-proof component 100 as a whole can be reduced, facilitating the integration of the transmission assembly 200 in space-constrained applications such as vehicles.

[0092] In a more specific embodiment, the body 110 of the leak-proof component 100 is made of, for example, rubber or metal. Based on the guide 210 forming a receiving cavity 210a to accommodate the body 110, the outer wall of the body 110 and the inner wall of the guide 210 forming the receiving cavity 210a form an interference fit, achieving a fixed connection between the guide 210 and the body 110, and causing at least a portion of the surface of the body 110 to fit against the inner wall of the guide 210 forming the receiving cavity 210a. Thus, lubricant can be filled only in the guide groove 210b, eliminating the need for or reducing the amount of spare grease to be filled in the receiving cavity 210a.

[0093] According to a third aspect of this application, a transmission device 300 is also provided, which includes the aforementioned transmission component 200 and is capable of performing transmission functions in equipment such as vehicles as at least part of the aforementioned transmission mechanism. It is understood that the transmission device 300, by integrating the aforementioned transmission component 200, possesses all the beneficial effects of the aforementioned transmission component 200, which will not be elaborated upon here.

[0094] In some embodiments, the transmission device 300 further includes a follower 220. The follower 220 is at least partially movably disposed within the body. The follower 220 is at least partially located within the guide groove 210b and is movable relative to the guide member 210. That is, the follower 220 is at least partially movably disposed within the guide groove 210b to form a follower connection with the guide member 210. Specifically, when the guide member 210 rotates, the follower 220 can slide relative to the guide member 210 under the guidance of the guide groove 210b. It is understandable that the follower 220 is the component that cooperates with the guide groove 210b in the transmission structure mentioned above. That is, the follower 220 moves relative to the guide 210 in a preset direction of movement by forming a wall surface cooperation with the guide 210 to form a guide groove 210b; or the follower 220 drives the guide 210 to move accordingly by forming a wall surface cooperation with the guide 210 to form a guide groove 210b, thereby realizing power transmission.

[0095] In some embodiments, the follower 220 includes a follower portion 221. The follower portion 221 is embedded in the guide groove 210b and contacts the groove wall of the guide groove 210b.

[0096] As an example, the follower 220 may be slidably connected to the guide 210 under the guidance of the guide groove 210b.

[0097] In a specific embodiment, the guide 210 is rotatably connected to the follower 220 around the rotation axis L2, so that the follower 220 slides when the guide 210 rotates around the rotation axis L2. In this case, the guide 210 can be connected to a drive (e.g., a rotary motor) to rotate under the drive of the drive. The follower 220 is rotatably connected to the guide 210 through the cooperation of the guide groove 210b and the follower part 221, and slides relative to the guide 210 when the guide 210 rotates. The follower 220 can be fixedly connected to an external device to drive the external device to move.

[0098] In a more specific embodiment, the transmission device 300 may be integrated into a shock absorber for example, to transmit the power provided by the drive component to the shock absorber and to adjust the corresponding structure of the shock absorber stiffness, so that the stiffness of the shock absorber is adjustable, and thus the shock absorber can be integrated into a vehicle as part of the active suspension.

[0099] In some embodiments, the follower 221 is located on the side of the edge 110b of the clearance channel near the guide groove 210b, so as to stop the follower 221 by the edge 110b of the clearance channel. Specifically, in the radial direction of the cylindrical body 110, the follower 221 is located on the side of the edge 110b of the clearance channel near the guide groove 210b. That is, in the radial direction of the body 110, the follower 221 is located between the bottom 210d of the guide groove and the edge 110b of the clearance channel, such that the edge 110b of the clearance channel also serves to confine the follower 221 within the guide groove 210b, reducing the possibility of the follower 220 carrying lubricant out of the guide groove 210b when it moves.

[0100] In some embodiments, the follower 220 further includes a connecting portion 222. The connecting portion 222 is connected to the follower 221 and is at least partially located outside the guide groove 210b. Specifically, the first side of the guide groove 210b is open and communicates with the clearance channel 110a, allowing the connecting portion 222 to pass through the clearance channel 110a from the first side and connect to the follower 221.

[0101] In a more specific embodiment, the bottom 210d of the guide groove can be located on a second side opposite to the first side. A connecting pin 222a is provided on the connecting part 222, which passes through the clearance channel 110a and inserts into the guide groove 210b. The follower part 221 is connected to the connecting part 222 via the connecting pin 222a. Thus, the follower part 221 can move synchronously with the connecting part 222.

[0102] In some embodiments, the body space 110c of the body 110 is used to accommodate the connecting portion 222. The body space 110c communicates with the clearance channel 110a so that at least a portion of the connecting portion 222 is connected from the clearance channel 110a to the follower portion 221. Another portion of the connecting portion 222 is movably disposed in the body space 110c under the action of the follower portion 221, so as to move within the body space 110c under the action of the follower portion 221. One end of the connecting portion 222 extends out of the body space 110c along the first direction X1, so as to facilitate connection to other devices by means of the portion of the connecting portion 222 extending out of the body space 110c, so as to drive these devices to move when the follower 220 is active.

[0103] In some embodiments, at least a portion of the surface of the leak-proof member 100 conforms to the inner wall of the receiving cavity 210a formed by the guide member 210, so that lubricant can be filled in the guide groove 210b, eliminating the need for or reducing the amount of spare grease to be filled in the receiving cavity 210a.

[0104] In a specific design, the leak-proof component 100 is made of, for example, rubber or metal. Regarding the fit between the guide component 210 and the leak-proof component 100, the guide component 210 and the leak-proof component 100 are, for example, fixedly connected or integrally formed.

[0105] In some embodiments, the end of the guide groove 210b along a predetermined extension direction is closed to contain the lubricant within the guide groove 210b and prevent it from being discharged from the end of the guide groove 210b.

[0106] In some embodiments, refer to Figure 5 As shown, the follower 220 is provided with a through hole 220a. The through hole 220a is connected to the body space 110c, and the through hole 220a can ensure the connection between the inside and outside of the body space 110c, so as to avoid the air pressure difference between the inside and outside of the body space 110c from interfering with the normal sliding of the follower 220.
