[0039] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0040] Reference below Figure 1-Figure 5 A universal joint cover 100 according to an embodiment of the present invention is described.

[0041] like Figure 1 and Figure 2 As shown, a universal joint cover 100 according to the present invention includes: a plurality of cover bodies 1, the plurality of cover bodies 1 are arranged in sequence along a first direction, and two adjacent cover bodies 1 are connected, each cover body 1 is formed with a corrugated portion 2, each corrugated portion 2 includes a plurality of connected connecting walls 21, and the angle between two adjacent connecting walls 21 of at least one cover body 1 is greater than or equal to 80° and less than or equal to 110°.

[0042] The universal joint cover 100 includes a plurality of cover bodies 1, for example, the cover bodies 1 may be provided with 2, 3 or more, and this application is described by taking the case where 2 cover bodies 1 are provided as an example, and the two cover bodies 1 are arranged in sequence along the first direction, that is, Figure 1 In the X direction, two adjacent sheath bodies 1 are connected. For example, two adjacent sheath bodies 1 can be directly connected by a snap connection, or two adjacent sheath bodies 1 can be connected to the same connection structure to achieve an indirect connection effect of the two adjacent sheath bodies 1 through the connection structure. The connection of two adjacent sheath bodies 1 can seal the internal structure of the sheath body 1, which is beneficial to the stable operation of the internal structure of the sheath body 1, thereby improving the working stability of the universal joint 200.

[0043] Each sheath body 1 is formed with a corrugated portion 2, and each corrugated portion 2 includes a plurality of connected connecting walls 21. For example, the plurality of connecting walls 21 can be integrally formed, but the present application is not limited thereto. As long as each corrugated portion 2 includes a plurality of connected connecting walls 21, the present application uses the integrally formed plurality of connecting walls 21 as an example for illustration. The integrally formed plurality of connecting walls 21 can improve the connection reliability of the plurality of connecting walls 21. When the vehicle is bumpy or turns at a large angle, the risk of separation of the plurality of connecting walls 21 due to force is reduced, thereby improving the working stability of the universal joint 200 and further improving the safety of the vehicle.

[0044] The angle between two adjacent connecting walls 21 of at least one jacket body 1 is greater than or equal to 80° and less than or equal to 110°. That is, the angle between two adjacent connecting walls 21 of at least one jacket body 1 can be set to any value between 80° and 110°. For example, the angle between two adjacent connecting walls 21 of at least one jacket body 1 can be set to 80°, 90°, 100°, 110°, etc. Such a setting can make the structure of the multiple connecting walls 21 of at least one jacket body 1 loose, and when the vehicle is bumpy or turns at a large angle, the risk of contact, extrusion, or even friction between the adjacent connecting walls 21 of the corrugated portion 2 is reduced.

[0045] Specifically, two jacket bodies 1 are arranged sequentially along a first direction and connected, achieving the effect of a split-body jacket design. This connection also seals the internal structure of the jacket bodies 1, facilitating stable operation of the internal structure of the jacket bodies 1, thereby improving the operational stability of the universal joint 200. Both jacket bodies 1 are formed with a corrugated portion 2, each of which includes a plurality of interconnected connecting walls 21. The angle between two adjacent connecting walls 21 of at least one jacket body 1 is greater than or equal to 80° and less than or equal to 110°. This arrangement results in a loose structure for the multiple connecting walls 21 of at least one jacket body 1, reducing the risk of contact, compression, or even friction between adjacent connecting walls 21, thereby reducing the risk of abnormal noise from the universal joint jacket 100 during vehicle operation.

[0046] Therefore, by providing multiple sleeve bodies 1, the effect of splitting the conventional sleeve structure is achieved, and the angle between two adjacent connecting walls 21 of the corrugated portion 2 on the sleeve body 1 is set to be greater than or equal to 80° and less than or equal to 110°, so that the multiple connecting walls 21 of the universal joint sleeve 100 can be made loose in structure. When the vehicle is bumpy or turns at a large angle, the risk of mutual contact, compression, or even friction between the adjacent connecting walls 21 of the corrugated portion 2 is reduced, thereby reducing the risk of abnormal noise generated by the universal joint sleeve 100 during vehicle driving.

[0047] In some embodiments of the present invention, Figure 3 As shown, the multiple connecting walls 21 of at least one sheath body 1 include: a first connecting wall 211, a second connecting wall 212, a third connecting wall 213 and a fourth connecting wall 214 connected in sequence along a first direction, the angle formed between the first connecting wall 211 and the second connecting wall 212 is greater than or equal to 80° and less than or equal to 90°, the angle formed between the second connecting wall 212 and the third connecting wall 213 is greater than or equal to 100° and less than or equal to 110°, and the angle formed between the third connecting wall 213 and the fourth connecting wall 214 is greater than or equal to 100° and less than or equal to 110°.

[0048] Among them, the multiple connecting walls 21 of at least one sleeve body 1 include a first connecting wall 211, a second connecting wall 212, a third connecting wall 213 and a fourth connecting wall 214 connected in sequence along the first direction. For example, the multiple connecting walls 21 can be integrally formed, but the present application is not limited to this. As long as each corrugated portion 2 includes a first connecting wall 211, a second connecting wall 212, a third connecting wall 213 and a fourth connecting wall 214 connected in sequence along the first direction, the present application takes the integral forming of multiple connecting walls 21 as an example for illustration. The integral forming can improve the connection reliability of the multiple connecting walls 21. When the vehicle is bumpy or turns at a large angle, the risk of separation of the multiple connecting walls 21 due to force is reduced, thereby improving the working stability of the universal joint 200 and further improving the safety of the vehicle.

[0049] The angle formed between the first connecting wall 211 and the second connecting wall 212 can be 80°, 85°, or 90°, but the present application is not limited thereto. The angle formed between the first connecting wall 211 and the second connecting wall 212 can also be any value between 80° and 90°. The angle formed between the second connecting wall 212 and the third connecting wall 213 can be 100°, 105°, or 110°, but the present application is not limited thereto. The angle formed between the second connecting wall 212 and the third connecting wall 213 can also be any value between 100° and 110°. The angle formed between the third connecting wall 213 and the fourth connecting wall 214 can be 100°, 105°, or 110°, but the present application is not limited thereto. The angle formed between the third connecting wall 213 and the fourth connecting wall 214 can also be any value between 100° and 110°.

[0050] This application uses the example that the angle formed between the first connecting wall 211 and the second connecting wall 212 is 80°, the angle formed between the second connecting wall 212 and the third connecting wall 213 is 110°, and the angle formed between the third connecting wall 213 and the fourth connecting wall 214 is 110°. Such a setting can make the structure of the multiple connecting walls 21 of the sleeve body 1 loose. When the vehicle is bumpy or turns at a large angle, it is beneficial to reduce the risk of contact, compression or even friction between any pair of adjacent connecting walls 21 between the first connecting wall 211, the second connecting wall 212, the third connecting wall 213 and the fourth connecting wall 214, thereby reducing the risk of abnormal noise generated by the universal joint sleeve 100 during vehicle driving.

[0051] In some embodiments of the present invention, Figure 3 As shown, the multiple connecting walls 21 of at least one sheath body 1 also include: a fifth connecting wall 215, the fifth connecting wall 215 is connected to the fourth connecting wall 214 and is located on the side of the fourth connecting wall 214 away from the third connecting wall 213, and the angle formed between the fourth connecting wall 214 and the fifth connecting wall 215 is greater than or equal to 80° and less than or equal to 100°.

[0052] Among them, the multiple connecting walls 21 of at least one sleeve body 1 can also include a fifth connecting wall 215, and the fifth connecting wall 215 is connected to the fourth connecting wall 214. For example, the fifth connecting wall 215 and the fourth connecting wall 214 can be integrally formed, but the present application is not limited to this. As long as the fifth connecting wall 215 is connected to the fourth connecting wall 214, the present application takes the integral forming of the fifth connecting wall 215 and the fourth connecting wall 214 as an example for illustration. The integral forming can improve the connection reliability between the fifth connecting wall 215 and the fourth connecting wall 214. When the vehicle is bumpy or turns at a large angle, the risk of force separation of the fifth connecting wall 215 and the fourth connecting wall 214 is reduced, thereby improving the working stability of the universal joint 200 and thereby improving the safety of the vehicle.

[0053] The fifth connecting wall 215 is located on the side of the fourth connecting wall 214 facing away from the third connecting wall 213. That is, along the first direction, the third connecting wall 213 and the fifth connecting wall 215 are respectively located on either side of the fourth connecting wall 214. The angle formed between the fourth connecting wall 214 and the fifth connecting wall 215 can be 80°, 90°, or 100°, but the present application is not limited thereto. The angle formed between the fourth connecting wall 214 and the fifth connecting wall 215 can also be any value between 80° and 100°. The present application uses the angle formed between the fourth connecting wall 214 and the fifth connecting wall 215 as an example to illustrate. This arrangement can make the third connecting wall 213, the fourth connecting wall 214, and the fifth connecting wall 215 loose in structure. When the vehicle is bumpy or turns at a large angle, it helps reduce the risk of contact, compression, or even friction between the third connecting wall 213 and the fourth connecting wall 214, and the fourth connecting wall 214 and the fifth connecting wall 215, thereby further reducing the risk of abnormal noise generated by the universal joint cover 100 during vehicle driving.

[0054] In some embodiments of the present invention, Figure 3 As shown, each corrugated portion 2 further includes a crest connecting section 22 and a trough connecting section 23. The outer ends of two adjacent connecting walls 21 are connected with the crest connecting section 22, and the inner ends of two adjacent connecting walls 21 are connected with the trough connecting section 23. Both the crest connecting section 22 and the trough connecting section 23 are arc-shaped.

[0055] In which, each corrugated portion 2 can also include a peak connecting section 22 and a trough connecting section 23, and the peak connecting section 22 and the trough connecting section 23 can connect two adjacent connecting walls 21 together, and the outer ends of the two adjacent connecting walls 21 are connected with the peak connecting section 22, and the inner ends of the two adjacent connecting walls 21 are connected with the trough connecting section 23, for example: the first connecting wall 211 and the second connecting wall 212 are connected with the peak connecting section 22, the second connecting wall 212 and the third connecting wall 213 are connected with the trough connecting section 23, the third connecting wall 213 and the fourth connecting wall 214 are connected with the peak connecting section 22, and the fourth connecting wall 214 and the fifth connecting wall 215 are connected with the trough connecting section 23, thereby achieving the effect of connecting the first connecting wall 211, the second connecting wall 212, the third connecting wall 213, the fourth connecting wall 214 and the fifth connecting wall 215 together through the peak connecting section 22 and the trough connecting section 23.

[0056] The crest connecting section 22 and the trough connecting section 23 are both arc-shaped. Setting the crest connecting section 22 and the trough connecting section 23 in an arc shape is beneficial to reducing the risk of stress concentration at the crest and the trough, thereby reducing the risk of any pair of adjacent connecting walls 21 between the first connecting wall 211, the second connecting wall 212, the third connecting wall 213, the fourth connecting wall 214 and the fifth connecting wall 215 being cracked or even disconnected due to stress.

[0057] In some embodiments of the present invention, Figure 3 As shown, both the wave crest connecting section 22 and the wave trough connecting section 23 are configured in an arc shape.

[0058] Among them, the peak connecting section 22 and the trough connecting section 23 can both be constructed in a circular arc shape. Setting the peak connecting section 22 and the trough connecting section 23 in a circular arc shape is beneficial to reducing the risk of stress concentration at the peak and the trough, thereby reducing the risk of any pair of adjacent connecting walls 21 between the first connecting wall 211, the second connecting wall 212, the third connecting wall 213, the fourth connecting wall 214 and the fifth connecting wall 215 being cracked or even disconnected due to stress, thereby improving the structural stability of the sheath body 1.

[0059] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, each sleeve body 1 includes a first assembly section 13 and a second assembly section 14, and the corrugated portion 2 is connected between the corresponding first assembly section 13 and the second assembly section 14. The multiple sleeve bodies 1 include a first sleeve body 11 and a second sleeve body 12. The first assembly section 13 of the first sleeve body 11 and the first assembly section 13 of the second sleeve body 12 are connected, and the second assembly section 14 of the first sleeve body 11 and the second assembly section 14 of the second sleeve body 12 are respectively connected to the bell housing 201 and the half-shaft shaft 202 of the universal joint 200.

[0060] Among them, each sheath body 1 includes a first assembly section 13 and a second assembly section 14. Along the first direction, the first assembly section 13 and the second assembly section 14 are arranged at both ends of the sheath body 1, so that the sheath body 1 can be assembled through the first assembly section 13 and the second assembly section 14, and the corrugated portion 2 is connected between the corresponding first assembly section 13 and the second assembly section 14. For example, the corrugated portion 2 and the corresponding first assembly section 13 and the second assembly section 14 can be integrally formed, but the present application is not limited to this, as long as the corrugated portion 2 is connected between the corresponding first assembly section 13 and the second assembly section 14. The present application takes the integral forming of the corrugated portion 2 and the corresponding first assembly section 13 and the second assembly section 14 as an example for explanation. The integral forming can improve the connection stability of the corrugated portion 2 and the first assembly section 13 and the second assembly section 14, thereby improving the working reliability of the sheath body 1.

[0061] The multiple sheath bodies 1 include a first sheath body 11 and a second sheath body 12. The first assembly section 13 of the first sheath body 11 and the first assembly section 13 of the second sheath body 12 are connected. The first assembly section 13 of the first sheath body 11 and the first assembly section 13 of the second sheath body 12 can be directly connected. The first assembly section 13 of the first sheath body 11 and the first assembly section 13 of the second sheath body 12 can also be indirectly connected through a connecting structure. The connection of the first assembly section 13 of the first sheath body 11 and the first assembly section 13 of the second sheath body 12 can connect the first sheath body 11 and the second sheath body 12, so that the first sheath body 11 and the second sheath body 12 can jointly play an angle and displacement compensation role.

[0062] The second assembly section 14 of the first sleeve body 11 is connected to the bell-shaped housing 201 of the universal joint 200, and the second assembly section 14 of the second sleeve body 12 is connected to the half-shaft shaft 202, thereby achieving the effect of assembling the first sleeve body 11 and the second sleeve body 12 on the universal joint 200. This is beneficial for the second sleeve body 12 to compensate for the angle and displacement of the vehicle when the vehicle turns at a large swing angle, thereby further reducing the risk of abnormal noise generated by the universal joint sleeve 100 during vehicle driving.

[0063] Furthermore, the universal joint cover 100 may further include a first clamp 4 and a second clamp 5. When the second assembly section 14 of the first cover body 11 is connected to the bell housing 201 of the universal joint 200 and the second assembly section 14 of the second cover body 12 is connected to the axle shaft 202, the first clamp 4 is sleeved on the outside of the second assembly section 14 of the first cover body 11. The first clamp 4 can lock and fix the second assembly section 14 of the first cover body 11 to the bell housing 201, thereby reliably connecting the second assembly section 14 of the first cover body 11 to the bell housing 201. The second clamp 5 is sleeved on the outside of the second assembly section 14 of the second cover body 12 and the axle shaft 202. The second clamp 5 can lock and fix the second assembly section 14 of the second cover body 12 to the axle shaft 202, thereby reliably connecting the second assembly section 14 of the second cover body 12 to the axle shaft 202.

[0064] In some embodiments of the present invention, Figure 3 As shown, the included angle between the second assembly section 14 connected to the bell-shaped housing 201 and the adjacent connecting wall 21 is greater than or equal to 130° and less than or equal to 140°.

[0065] Among them, the angle between the second assembly section 14 connected to the bell-shaped housing 201 and the adjacent connecting wall 21 is greater than or equal to 130° and less than or equal to 140°, that is, the angle between the second assembly section 14 connected to the bell-shaped housing 201 and the adjacent connecting wall 21 can be set to any value between 130° and 140°, for example: the angle between the second assembly section 14 connected to the bell-shaped housing 201 and the adjacent connecting wall 21 can be set to 130°, 135° or 140°.

[0066] This application is illustrated by taking the example of setting the angle between the second assembly section 14 connected to the bell-shaped housing 201 and the adjacent connecting wall 21 to be 135°. As an embodiment of the present application, the second assembly section 14 of the first sleeve body 11 is connected to the bell-shaped housing 201, and the angle between the second assembly section 14 of the first sleeve body 11 and the first connecting wall 211 of the first sleeve body 11 is 135°. Such a setting can make the structure of the first sleeve body 11 looser. When the vehicle is bumpy or turns at a large angle, the risk of mutual contact, extrusion or even friction between the second assembly section 14 of the first sleeve body 11 and the first connecting wall 211 of the first sleeve body 11 can be reduced, thereby further reducing the risk of abnormal noise generated by the universal joint sleeve 100 during vehicle driving.

[0067] In some embodiments of the present invention, Figure 1 and Figure 2As shown, the universal joint cover 100 may further include: a connecting ring 3, a first assembly section 13 of the first cover body 11 and a first assembly section 13 of the second cover body 12 are fitted together, a first positioning protrusion 131 is formed on the inner wall of the inner first assembly section 13, a first positioning groove 31 is formed on the outer peripheral wall of the connecting ring 3, the connecting ring 3 is assembled in the inner first assembly section 13, and the first positioning protrusion 131 is assembled in the first positioning groove 31.

[0068] Among them, the first assembly section 13 of the first sleeve body 11 and the first assembly section 13 of the second sleeve body 12 are sleeved and matched, and the universal joint sleeve 100 can also include a connecting ring 3, which can be set as a metal part. Setting the connecting ring 3 as a metal part can improve the working stability of the connecting ring 3, so that the connecting ring 3 can reliably support the first assembly section 13 of the first sleeve body 11 and the first assembly section 13 of the second sleeve body 12, thereby improving the assembly stability of the first assembly section 13 of the first sleeve body 11 and the first assembly section 13 of the second sleeve body 12.

[0069] As an embodiment of the present application, the first assembly section 13 of the first sheath body 11 can be sleeved on the outside of the first assembly section 13 of the second sheath body 12 to connect the first sheath body 11 and the second sheath body 12. The inner side wall of the inner first assembly section 13 can be formed with a first positioning protrusion 131, and the outer peripheral wall of the connecting ring 3 can be formed with a first positioning groove 31. The first positioning protrusion 131 is adapted to the size and structure of the first positioning groove 31. When the connecting ring 3 is assembled in the inner first assembly section 13, the first positioning protrusion 131 is assembled in the first positioning groove 31, which facilitates the positioning and connection between the inner first assembly section 13 and the connecting ring 3, thereby ensuring reliable assembly of the inner first assembly section 13 and the connecting ring 3, and also improving the sealing performance between the inner first assembly section 13 and the connecting ring 3.

[0070] Furthermore, the universal joint cover 100 may also include a connecting clamp 6, which can be sleeved on the outside of the first assembly section 13 of the first cover body 11 and the first assembly section 13 of the second cover body 12. The connecting clamp 6 locks and fixes the first assembly section 13 of the first cover body 11 and the first assembly section 13 of the second cover body 12, which is beneficial to improve the connection reliability between the first cover body 11 and the second cover body 12, so that the first cover body 11 and the second cover body 12 cooperate with each other, while meeting the requirements of the vehicle jumping up and down due to road bumps and large-angle turning, reducing the risk of abnormal noise generated by the multiple connecting walls 21 of the cover body 1 due to mutual squeezing.

[0071] In some embodiments of the present invention, Figure 1 and Figure 2As shown, the outer side wall of the inner first assembly section 13 is formed with one of the second positioning protrusion 132 and the second positioning groove 141, and the inner side wall of the outer first assembly section 13 is formed with the other of the second positioning protrusion 132 and the second positioning groove 141, and the second positioning protrusion 132 is assembled in the second positioning groove 141.

[0072] Among them, the outer side wall of the inner first assembly section 13 can be formed with one of the second positioning protrusion 132 and the second positioning groove 141, and the inner side wall of the outer first assembly section 13 can be formed with the other of the second positioning protrusion 132 and the second positioning groove 141. This application is explained by taking the outer side wall of the inner first assembly section 13 as an example in which the second positioning groove 141 is formed and the inner side wall of the outer first assembly section 13 can be formed with the second positioning protrusion 132. The second positioning protrusion 132 is assembled in the second positioning groove 141, and the size structure of the second positioning protrusion 132 is adapted to the second positioning groove 141, which facilitates the positioning connection between the inner first assembly section 13 and the outer first assembly section 13, so that the first sheath body 11 and the second sheath body 12 can be reliably assembled, and the sealing of the first sheath body 11 and the second sheath body 12 can be improved.

[0073] like Figure 1 and Figure 2 As shown, the universal joint 200 according to the present invention includes: a bell-shaped housing 201 and a half-shaft shaft 202 ; a universal joint sleeve 100 , which is the universal joint sleeve 100 of the above embodiment, and is connected between the bell-shaped housing 201 and the half-shaft shaft 202 .

[0074] The universal joint 200 includes a bell-shaped housing 201, a half-shaft shaft 202, and a universal joint sleeve 100. At least a portion of the half-shaft shaft 202 is assembled within the bell-shaped housing 201. The universal joint sleeve 100 is the universal joint sleeve 100 of the above-mentioned embodiment and is connected between the bell-shaped housing 201 and the half-shaft shaft 202. Furthermore, the universal joint 200 also includes a retainer 203, a star-shaped sleeve 204, and a steel ball 205. The retainer 203, star-shaped sleeve 204, and steel ball 205 are all assembled within the bell-shaped housing 201, which facilitates the stable operation of the universal joint 200. Therefore, by providing multiple sleeve bodies 1, the effect of splitting the conventional sleeve structure is achieved, and the angle between two adjacent connecting walls 21 of the corrugated portion 2 on the sleeve body 1 is set to be greater than or equal to 80° and less than or equal to 110°, so that the multiple connecting walls 21 of the universal joint sleeve 100 can be made loose in structure. When the vehicle is bumpy or turns at a large angle, the risk of mutual contact, compression, or even friction between the adjacent connecting walls 21 of the corrugated portion 2 is reduced, thereby reducing the risk of abnormal noise generated by the universal joint sleeve 100 during vehicle driving.
