Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a pull ring and a vehicle. Background Art

[0002] Conventional vehicles, such as trucks, are usually provided with pull rings on the inner wall of the cargo hold for securely loading cargo in the cargo hold.

[0003] The existing pull ring includes a mounting part for installation on the inner wall of the cargo hold and an annular structure movably connected to the mounting part. An electrophoretic layer is usually formed on the surfaces of the mounting part and the annular structure. Friction is easily generated at the contact part between the mounting part and the annular structure due to movement, which leads to damage of the electrophoretic layer, making the pull ring prone to rust in the later stage and shortening the service life of the pull ring.

[0024] The technical solution of this application will be described in detail below with reference to the accompanying drawings.

[0025] Here, the technical solutions in the embodiments (or "implementations") of the present application will be clearly and completely described in conjunction with the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0026] If there are terms related to directional indications or positional relationships in the embodiments of this application (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationship, movement, etc. between the components in a specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indication or positional relationship will also change accordingly. In addition, the terms "first" and "second" in the embodiments of this application are only used for the purpose of convenience of description and should not be understood as indicating or implying relative importance.

[0027] See also Figure 1 and Figure 2 The present application provides a pull ring, comprising: an annular structure 1, a mounting member 2 and a bushing 3, wherein the annular structure 1 is used to stabilize the transport body. The mounting member 2 is sleeved on a portion of the annular wall of the annular structure 1. The bushing 3 is arranged between the mounting member 2 and the portion of the annular wall, and the hardness of the portion of the annular wall and the mounting member 2 are both greater than the hardness of the bushing 3. Exemplarily, the annular structure 1 has a space portion formed by an inner circle a and an annular wall portion located between the inner circle a and the outer circle b, a portion of the annular wall of the annular structure 1 is used to cooperate with the mounting member 2 for installation, and another portion of the annular wall is used to stabilize the transport body. For example, when the transport body is cargo, another portion of the annular wall of the annular structure 1 cooperates with a binding belt to facilitate the restraint of the cargo, thereby protecting people on the vehicle from being injured by the movement of the cargo.

[0028] The above scheme can avoid direct contact between the mounting part 2 and the part of the ring wall by setting the bushing 3 with lower hardness between the mounting part 2 and the part of the ring wall of the annular structure 1. During the flipping of the annular structure 1 relative to the mounting part 2, the annular structure 1 and the mounting part 2 with higher strength can resist the invasion and scratching of the bushing 3 with lower hardness, reduce the probability of friction damage between the mounting part 2 and the part of the ring wall, prevent the electrophoretic layer from being damaged as much as possible, and thus extend the service life of the pull ring.

[0029] In one embodiment, the bushing 3 is a flexible bushing 3. Exemplarily, the flexible bushing 3 can be an elastic bushing 3 or a plastic bushing 3, but it is not limited thereto. In one embodiment, the flexible bushing 3 is in an elastically deformed state between the mounting member 2 and the partial annular wall. As a result, a certain damping effect can be generated during the flipping process of the annular structure 1, effectively controlling the flipping force when the annular structure 1 flips, making the flipping process more stable. In one embodiment, the gap between the mounting member 2 and the partial annular wall is 0.5 to 1 mm, and the thickness of the flexible bushing 3 is 1 to 1.5 mm. As a result, when the flexible bushing 3 is installed in the gap between the mounting member 2 and the partial annular wall, it can be in an extruded state to ensure that the flexible bushing 3 can play a better damping effect. Of course, the size of the gap between the mounting member 2 and the partial annular wall, as well as the size of the thickness of the flexible bushing 3 are not limited thereto.

[0030] In one embodiment, the flexible bushing 3 is split along the surface generatrix of the portion of the annular wall. A surface generatrix refers to a line formed by rotating a circle around a central axis. For example, a straight annular wall is formed by rotating a straight line around the central axis, and this straight line can be called a surface generatrix. For another example, a curved annular wall is formed by rotating a curve around the central axis, and this curve can be called a surface generatrix. This facilitates fitting the flexible bushing 3 onto the portion of the annular wall of the annular structure 1 without affecting the overall strength of the annular structure 1.

[0031] See also Figure 1 In one embodiment, the mounting member 2 includes a mounting sleeve 21 and a mounting plate 22 connected to each other. The mounting sleeve 21 is sleeved on the portion of the annular wall, and the mounting plate 22 is provided with a fixing hole 23 for a fixing member to pass through. Thus, the pull ring can be fixed to the inner wall of the vehicle cabin by using a fixing member including but not limited to a screw passing through the fixing hole 23. For example, the mounting sleeve 21 and the mounting plate 22 can be processed separately and then connected together, and the connection method includes but is not limited to welding. Of course, in other examples, the mounting sleeve 21 and the mounting plate 22 can also be formed integrally.

[0032] It should be noted that the shape of the mounting plate 22 can be any shape such as a triangle or a quadrilateral.

[0033] See also Figure 2 In one embodiment, the annular structure 1 includes a straight portion 10 and a curved portion 11, and the partial annular wall is the outer circumferential wall of the straight portion 10. This ensures stability and smoothness during flipping of the annular structure 1. In one embodiment, the intersection of the straight portion 10 and the curved portion 11 forms a smooth transition. This prevents interference with the mounting sleeve 21 and maintains stability during flipping.

[0034] Please continue reading Figure 1 and Figure 2 In one embodiment, the mounting member 2 includes two mounting plates 22, which are integrally bent from the same plate as the mounting sleeve 21. The two mounting plates 22 fit snugly against each other and have the fixing holes 23 defined at the same locations. This prevents any weak points in the connection between the mounting sleeve 21 and the mounting plates 22, thereby enhancing the structural strength of the pull ring.

[0035] For example, the fixing holes 23 are provided at the center of the two mounting plates 22. This effectively distributes the tightening force evenly around the mounting plates 22, reducing local stress concentration and lowering the risk of deformation or breakage of the mounting plates 22. Of course, in other examples, the location design of the fixing holes 23 is not limited to this.

[0036] The present application also provides a vehicle, comprising a cabin, wherein the inner wall of the cabin is installed with any of the pull rings described above.

[0037] It should be noted that the technical solutions or technical features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of this application shall be included in the scope of protection of this application.
