[0032] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein 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 with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.
[0033] The following is for reference. Figures 1-7 This application describes a hinge 100 and a windshield protection assembly for a vehicle, according to embodiments of the present application.
[0034] This application discloses a hinge 100 for a vehicle windshield protection assembly. The hinge 100 includes a first hinge member 11 and a second hinge member 12, which are rotatably connected via a pivot 131. The first hinge member 11 is provided with a limiting member, and the second hinge member 12 has a first limiting portion and a second limiting portion. When the second hinge member 12 rotates relative to the first hinge member 11, it can selectively drive the first limiting portion and the second limiting portion to rotate around the pivot 131, so as to allow the first limiting portion or the second limiting portion to selectively move to a limiting position. The limiting member moves relative to the first hinge member 11 in a direction parallel to the pivot 131, so as to allow selective engagement with the first limiting portion or the second limiting portion in the limiting position.
[0035] According to the hinge 100 of this application, the first hinge member 11 is provided with a limiting member, and the second hinge member 12 is formed with a first limiting portion and a second limiting portion. The limiting positions of the first limiting portion and the second limiting portion refer to the positions that can cooperate with the limiting member for limiting. When the limiting member cooperates with the first limiting portion, it restricts the movement of the first hinge member 11 relative to the second hinge member 12, and the hinge 100 is in the first limiting state, such as... Figure 1 As shown; the limiting member cooperates with the second limiting part to restrict the movement of the first hinge member 11 relative to the second hinge member 12, and the hinge 100 is in the second limiting state, as shown. Figure 2 As shown. In the first and second limiting states, the hinge 100 of this application has different included angles between the first hinge member 11 and the second hinge member 12, which can be adapted to the needs of the windshield protection assembly for blocking or opening. The hinge 100 of this application can achieve the limiting state or release the limiting state simply by moving the limiting member, without the need to disassemble or install the limiting member or other structures. The operation is simple and quick, and it can be adapted to change the shape of the windshield protection assembly in emergency situations.
[0036] According to the hinge 100 of this application, since the limiting member and the first limiting part and the second limiting part can be selectively matched, the hinge 100 can realize two limiting states, thus it can be applied to windshield protection components, so that it can maintain a stable shape in both open and closed states; by moving the limiting member in the direction of parallel rotation axis 131 and rotating the first limiting part and the second limiting part, alignment and limiting cooperation are achieved, the operation is simple and quick, and the structure is lightweight, which can meet the needs of windshield protection components.
[0037] According to some embodiments of this application, the limiting member is constructed as a limiting pin 14, and the first limiting part is constructed as a limiting hole 122. The limiting groove and the limiting hole 122 are connected to each other to restrict the relative rotation of the first hinge member 11 and the second hinge member 12. The first hinge member 11 has a mounting hole 113, which extends in a direction parallel to the rotation axis 131. The limiting pin 14 is movably disposed in the mounting hole 113 and is adapted to selectively extend out of the mounting hole 113. In this embodiment, as... Figure 3 As shown, the limiting component is a limiting pin 14, and the first limiting part is a limiting hole 122. The hinge 100 is limited by the cooperation between the limiting pin 14 and the limiting hole 122. The cooperation method is simple and easy to operate. Moreover, the limiting pin 14 is set in the mounting hole 113 extending parallel to the direction of the rotating shaft 131. The limiting hole 122 rotates around the rotating shaft 131 to be directly opposite the limiting pin 14 in the extension direction of the mounting hole 113, which has high alignment accuracy.
[0038] In some embodiments, the end of the limiting hole 122 near the first hinge member 11 is chamfered to allow the limiting pin 14 to extend into it.
[0039] According to some embodiments of this application, the second limiting part is constructed as a stop surface 123, which is parallel to the center of the rotating shaft 131. The limiting pin 14 abuts against the stop surface 123 to restrict the unidirectional relative rotation of the first hinge member 11 and the second hinge member 12. In this embodiment, the hinge 100 is unidirectionally limited by the cooperation between the stop surface 123 and the limiting pin 14. When the stop surface 123 cooperates with the limiting pin 14, it does not need to be precisely aligned axially with the limiting pin 14. The cooperation method is simple and efficient. Moreover, the stop surface 123 is easy to process and form, which is suitable for unidirectional limiting situations, especially for unidirectional limiting of windshield protection components when they are covered, which can prevent them from accidentally flipping open.
[0040] According to some embodiments of this application, a spring 15 is provided in the mounting hole 113. One end of the spring 15 is connected to the first hinge member 11, and the other end is connected to the limiting pin 14. The spring 15 is adapted to restrict the movement of the limiting pin 14 away from the second hinge member 12. When the spring 15 is in its natural state, the limiting pin 14 protrudes from the first hinge member 11 and cooperates with the limiting hole 122 or the stop surface 123 for limiting. In this embodiment, as... Figure 3As shown, the spring 15 enables the limiting pin 14 to have a reset function. In actual use, the limiting pin 14 can be moved away from the second hinge 12 by external force to release the limitation. When the second hinge 12 moves to the target limiting position, the external force is released, and the limiting pin 14 can extend out of the limiting hole 122 under the action of the spring 15 to cooperate with the limiting hole 122 or the stop surface 123. This embodiment can further simplify the movement operation of the limiting pin 14 and improve the state switching efficiency of the hinge 100.
[0041] According to some embodiments of this application, the limiting pin 14 includes a first shaft segment 141, a second shaft segment 142, and a third shaft segment 143. The first shaft segment 141, the second shaft segment 142, and the third shaft segment 143 are sequentially connected axially, and the diameter of the second shaft segment 142 is larger than that of the first shaft segment 141 and the third shaft segment 143. The first shaft segment 141 is adapted to engage with the limiting hole 122 or the stop surface 123 for limiting; the second shaft segment 142 is slidably connected to the mounting hole 113; and a spring 15 is sleeved on the outer periphery of the third shaft segment 143, with one end connected to the second shaft segment 142. In this embodiment, as... Figure 3 As shown, the spring 15 is installed and used to move the limiting pin 14 by setting the second shaft segment 142 to slide with the mounting hole 113, setting the first shaft segment 141 to limit the movement of the limiting hole 122 or the stop surface 123, and setting the third shaft segment 143. The diameter of the first shaft segment 141 is smaller than that of the second shaft segment 142, allowing for a certain gap between the first shaft segment 141 and the mounting hole 113, and a certain gap between the first shaft segment 141 and the limiting hole 122 or the stop surface 123. This avoids structural collisions caused by excessively small gaps, allowing for a certain error when the second hinge 12 rotates, thereby reducing operational complexity and simplifying the operation process. The diameter of the third shaft segment 143 is smaller than that of the second shaft segment 142. The second shaft segment 142 can provide an axial mounting surface or abutment surface for the spring 15, enabling an axial force engagement between the spring 15 and the limiting pin 14.
[0042] Furthermore, a bushing 16 is also provided inside the mounting hole 113. The bushing 16 slides with the second shaft section 142, which can reduce the friction and wear between the limit pin 14 and the components inside the mounting hole 113.
[0043] According to some embodiments of this application, a limiting end cap 17 is provided on the second hinge member 12. The limiting end cap 17 is fixedly disposed at the end of the mounting hole 113 away from the first hinge member 11, and the limiting pin 14 passes through the limiting end cap 17. The other end of the spring 15 is connected to the limiting end cap 17. In this embodiment, as shown... Figure 3As shown, the movement range of the limiting pin 14 is limited by the limiting end cap 17 to prevent it from dislodging from the mounting hole 113. Simultaneously, the axial end cap 17 also provides an axial mounting surface or abutment surface for the spring 15, which, combined with the structure of the limiting pin 14, ensures that both ends of the spring 15 are subjected to axial force. Specifically, the limiting end cap 17 can be mounted on one side surface of the first hinge member 11 via the limiting bolt 18.
[0044] Furthermore, the first hinge member 11 has a connecting portion 111 and a mounting portion 112. The connecting portion 111 is provided with a first rotating shaft mounting hole 114, and the second hinge member 12 is provided with a second rotating shaft mounting hole 121. The rotating shaft 131 is disposed in the first rotating shaft mounting hole 114 and the second rotating shaft mounting hole 121 to realize the rotatable connection between the first hinge member 11 and the second hinge member 12. The mounting portion 112 is disposed on the connecting portion 111 and located on the side away from the second hinge member 12, and the mounting hole 113 is formed in the mounting portion 112. In this embodiment, the length of the mounting portion 112 along the extension direction of the rotating shaft 131 is greater than that of the connecting portion 111, which can realize the installation of the limiting member and the spring 15 and other structures, and maintain the stability and reliability of the limiting member.
[0045] According to some embodiments of this application, the hinge 100 further includes a buffer assembly. The buffer assembly connects the first hinge 11 and the second hinge 12 and is adapted to absorb part of the kinetic energy of the first hinge 11 when it rotates relative to the second hinge 12. In this embodiment, by providing the buffer assembly, a buffering effect can be achieved when the second hinge 12 rotates relative to the first hinge 11, preventing structural collisions and damage caused by excessive rotation speed during accidental rotation. This embodiment is particularly suitable for providing buffer protection for the windshield protection assembly when it rotates under gravity.
[0046] According to some embodiments of this application, the buffer assembly is constructed as a torsion spring 132, which is sleeved on the outside of the rotating shaft 131, with one end connected to the first hinge member 11 and the other end connected to the second hinge member 12. In this embodiment, as... Figure 3 As shown, the buffer assembly is constructed as a torsion spring 132, which is simple in structure and easy to obtain.
[0047] In some embodiments, a shaft anti-wear sleeve 133 is provided in the first shaft mounting hole 114 and the second shaft mounting hole 121 to protect the shaft 131 and reduce wear.
[0048] According to some embodiments of this application, a pull ring 19 is provided at the end of the limiting member away from the second hinge member 12. In this embodiment, the pull ring 19 facilitates the operation of the moving limiting pin 14.
[0049] This application also proposes a windshield protection assembly for a vehicle, which includes a mounting frame 300 and a protective plate 200. The mounting frame 300 is disposed on the outer periphery of the windshield. The protective plate 200 is rotatably disposed on the mounting frame 300 to selectively shield the windshield. The protective plate 200 and the mounting frame 300 are connected by the aforementioned hinge 100.
[0050] According to the windshield protection component of this application, such as Figure 1 , 2 As shown in Figure 7, the protective plate 200 is connected to the mounting frame 300 via the hinge 100. When the hinge 100 is in the first limiting state, the limiting member cooperates with the first limiting part to restrict the protective plate 200 from rotating relative to the mounting frame 300 in the first and second directions. At the same time, combined with the supporting force of the rotating shaft 131, the protective plate 200 is balanced by forces and maintains a stable shape. The protective plate 200 is in an open state and does not affect the normal use of the windshield. When the hinge 100 is in the second limiting state, the protective plate 200 is parallel to or at a small angle to the mounting frame 300. The limiting member cooperates with the second limiting part to restrict the protective plate 200 from rotating relative to the mounting frame 300. The protective plate 200 is balanced by forces and maintains a stable shape. The protective plate 200 is in a blocking state, providing effective protection for the windshield.
[0051] Furthermore, when the protective plate 200 is in the blocked state, due to gravity, it does not tend to flip in the first direction without external force. Therefore, the second limiting part can be simplified in design. For example, in the hinge 100 structure described above, the second limiting part is constructed as a stop surface 123, which plays a certain limiting role on the protective plate 200, restricting the protective plate 200 from rotating relative to the mounting frame 300 in the first direction, and preventing accidental opening by external force. Further, a third limiting part is formed on the first hinge member 11, which cooperates with the second hinge member 12 to achieve unidirectional limiting of the second hinge member 12; or a third limiting part is formed on the mounting frame 300, which cooperates with the protective plate 200 to achieve unidirectional limiting of the protective plate 200. Specifically, the third limiting part restricts the second hinge member 12 or the protective plate 200 from flipping in the second direction, and in combination with the stop surface 123, achieves rotational limiting of the second hinge member 12 and the protective plate 200, thereby maintaining structural stability.
[0052] In actual use, the hinge 100 and windshield protection assembly of this application are initially in the open state of the protective plate 200. At this time, the limiting pin 14 cooperates with the limiting hole 122 to limit the protective plate 200. Figure 4 As shown; by moving the limiting pin with external force, it moves away from the second hinge member 12, and the third shaft segment 143 exits the limiting hole 122. At this time, the limiting pin 14 disengages from the first limiting part, and the second hinge member 12 can rotate freely relative to the first hinge member 11, as shown. Figure 5As shown; rotate the protective plate 200 to the blocking state. At this time, the stop surface 123 is opposite to the limit pin 14. Move the limit pin 14 or make the limit pin 14 move towards the second hinge member 12 under the action of the spring return force, so that the first hinge member 11 protrudes and cooperates with the stop surface 123 to achieve the limit. Figure 6 As shown.
