[0023] This utility model provides a sleeve structure, a vehicle body structural component, and a vehicle. The following detailed description is provided in conjunction with specific embodiments.

[0024] like Figure 1 and Figure 2 As shown in the figure, a sleeve structure provided by this utility model embodiment includes a first sleeve 1 and a second sleeve 2; the first sleeve 1 has a first protrusion 11 on its circumference, and the first sleeve 1 is used to be inserted into the mounting hole 31 of the beam 3, and the first protrusion 11 is used to be located on one side of the beam 3; the second sleeve 2 has a second protrusion 21 on its circumference, and the second sleeve 2 is used to be inserted into the first sleeve 1 and its outer wall is threaded to the inner wall of the first sleeve 1, and the second protrusion 21 is used to be located on the other side of the beam 3.

[0025] It should be noted that one side and the other side of beam 3 are the two sides of beam 3 that are penetrated by mounting holes 31, as shown below. Figure 1 As shown, the two ends of the mounting hole 31 penetrate the left and right sides of the beam 3, respectively. One side of the beam 3 is its left side, and the other side of the beam 3 is its right side. Therefore, the first protrusion 11 can be located on the left side of the beam 3, and the second protrusion 21 can be located on the right side of the beam 3. Specifically, the inner wall of the first sleeve 1 can be provided with internal threads, and the outer wall of the second sleeve 2 can be provided with external threads. The inner wall of the first sleeve 1 and the outer wall of the second sleeve 2 are threaded together by the engagement of the internal threads and the external threads.

[0026] In this embodiment, the two sleeves are detachably connected by inserting the second sleeve 2 into the first sleeve 1 and threading its outer wall to the inner wall of the first sleeve 1. A first protrusion 11 is provided on the periphery of the first sleeve 1 to abut against one side of the beam 3, and a second protrusion 21 is provided on the periphery of the second sleeve 2 to abut against the other side of the beam 3. Thus, when the second sleeve 2 is screwed into the first sleeve 1 until the first protrusion 11 and the second protrusion 21 abut against the two sides of the beam 3 respectively, the sleeve structure can be installed on the beam 3. When the second sleeve 2 is screwed out of the first sleeve 1 until the second sleeve 2 is completely separated from the first sleeve 1, the sleeve structure can be removed from the beam 3. Finally, the sleeve structure can be detachably installed on the beam 3. When the sleeve structure is damaged, it can be disassembled and replaced without damaging the beam 3, reducing the difficulty of maintenance. In addition, when the second sleeve 2 is screwed into the first sleeve 1 to different depths, the distance between the first protrusion 11 and the second protrusion 21 will be different, so as to be able to adapt to beams 3 of different sizes, thereby improving the versatility of the sleeve structure.

[0027] Optionally, the inner hole of the second sleeve 2 is a through hole (refer to...). Figure 7 ) or threaded hole (refer to) Figure 1 ).

[0028] In this optional embodiment, when the sleeve structure is installed on the beam 3 to perform the connecting function, the joints (such as bolts, brackets, etc.) can be inserted into the second sleeve 2 to achieve fixation. That is, the inner hole of the second sleeve 2 can be used as the installation channel for the joints. Therefore, if the inner hole of the second sleeve 2 is set as a threaded hole, it can meet the installation requirements of joints that need to be screwed. If the inner hole of the second sleeve 2 is set as a through hole (a hole without threads), it can meet the installation requirements of joints that do not need to be screwed.

[0029] Optionally, such as Figure 3 and Figure 4 As shown, the direction of the thread in the threaded hole is the same as the direction of the thread on the outer wall of the second sleeve 2.

[0030] Specifically, such as Figure 3 and Figure 5 As shown, the inner wall thread of the first sleeve 1 is designated as the first thread 12, the outer wall thread of the second sleeve 2 is designated as the second thread 22, and the inner wall thread of the second sleeve 2 (i.e. the thread of the threaded hole) is designated as the third thread 23. The first thread 12 matches the second thread 22, and the second thread 22 and the third thread 23 have the same direction of rotation. For example, the second thread 22 and the third thread 23 are both left-handed or right-handed.

[0031] In this optional embodiment, by making the direction of the thread of the threaded hole the same as the direction of the thread of the outer wall of the second sleeve 2, when the handpiece is screwed into the threaded hole, the handpiece will drive the thread connection between the outer wall of the second sleeve 2 and the inner wall of the first sleeve 1 to become tighter, so as to prevent the second sleeve 2 and the first sleeve 1 from loosening.

[0032] Optionally, such as Figure 3 As shown, the cross-sectional dimension of the threaded hole is smaller than the cross-sectional dimension of the threaded tooth on the outer wall of the second sleeve 2.

[0033] Specifically, such as Figure 3 As shown, the major diameter, minor diameter, tooth height, and pitch of the threaded hole (third thread 23) are smaller than the major diameter, minor diameter, tooth height, and pitch of the threaded tooth on the outer wall of the second sleeve 2 (second thread 22), so that the cross-sectional size of the threaded hole is smaller than the cross-sectional size of the threaded tooth on the outer wall of the second sleeve 2.

[0034] In this optional embodiment, by setting the thread cross-sectional size of the threaded hole to be smaller than the thread cross-sectional size of the outer wall of the second sleeve 2, the force required to screw the handpiece into the threaded hole is much less than the force required to screw the second sleeve 2 into the first sleeve 1. This can prevent the threads between the second sleeve 2 and the first sleeve 1 from being damaged when the handpiece is screwed in, and avoid the failure of the thread engagement between the two sleeves.

[0035] It should be noted that in the second sleeve 2, the difference between the minor diameter of the second thread 22 and the major diameter of the third thread 23 is greater than 2.5 times the pitch of the second thread 22, that is, the wall thickness of the second sleeve 2 is greater than 2.5 times the pitch of the second thread 22, which can ensure the structural strength of the second sleeve 2; in the first sleeve 1, the difference between the outer diameter of the first sleeve 1 and the major diameter of the first thread 12 is greater than 2.5 times the pitch of the first thread 12, that is, the wall thickness of the first sleeve 1 is greater than 2.5 times the pitch of the first thread 12, which can ensure the structural strength of the first sleeve 1.

[0036] Optionally, such as Figure 4 and Figure 6 As shown, one end of the first sleeve 1 protrudes outward in the circumferential direction to form the first protrusion 11, and one end of the second sleeve 2 protrudes outward in the circumferential direction to form the second protrusion 21.

[0037] It should be noted that one end of the first sleeve 1 is the left end of the first sleeve 1, and one end of the second sleeve 2 is the right end of the second sleeve 2. It should also be noted that the first sleeve 1 protrudes outward in the circumferential direction, meaning that one end of the first sleeve 1 protrudes outward in the circumferential direction, thus forming a first protrusion 11 that is roughly a ring-shaped structure; similarly, the second sleeve 2 protrudes outward in the circumferential direction, meaning that one end of the second sleeve 2 protrudes outward in the circumferential direction, thus forming a second protrusion 21 that is also roughly a ring-shaped structure.

[0038] In this optional embodiment, by protruding one end of the first sleeve 1 outward in the circumferential direction to form a first protrusion 11, and by protruding one end of the second sleeve 2 outward in the circumferential direction to form a second protrusion 21, the two protrusions are approximately annular structures. This can increase the contact area between the sleeve structure and the side of the beam 3, which is beneficial to disperse the pressure exerted by the sleeve structure on the beam 3 and prevent the surface of the beam 3 from deforming.

[0039] Optionally, such as Figure 5 As shown, the end face of the first protrusion 11 away from the other end of the first sleeve 1 is provided with a first strip groove 111 arranged radially along the first sleeve 1.

[0040] It should be noted that the other end of the first sleeve 1 is the right end of the first sleeve 1. Specifically, one or more first strip grooves 111 can be provided, for example, there are four first strip grooves 111, of which two first strip grooves 111 are arranged opposite each other along the first radial direction of the first sleeve 1, and the other two first strip grooves 111 are arranged opposite each other along the second radial direction of the first sleeve 1, wherein the first radial direction and the second radial direction of the first sleeve 1 are perpendicular to each other.

[0041] It is understandable that, since the first sleeve 1 is inserted into the mounting hole 31 of the beam 3, when the second sleeve 2 is screwed into the first sleeve 1, the second sleeve 2 may cause the first sleeve 1 to rotate relative to the mounting hole 31, affecting the normal installation of the sleeve structure. In this optional embodiment, by providing a first strip groove 111 radially arranged along the first sleeve 1 on the end face of the first protrusion 11 away from the first sleeve 1, when the second sleeve 2 is screwed into the first sleeve 1, a tool can be simultaneously inserted into the first strip groove 111 to restrict the rotation of the first sleeve 1, ensuring that the second sleeve 2 is smoothly screwed into the first sleeve 1, thus ensuring the normal installation of the sleeve structure.

[0042] Optionally, such as Figure 2 and Figure 3 As shown, the end face of the second protrusion 21 away from the other end of the second sleeve 2 is provided with a second strip groove 211 arranged radially along the second sleeve 2.

[0043] It should be noted that the other end of the second sleeve 2 is the left end of the second sleeve 2. Specifically, one or more second strip grooves 211 can be provided, for example in... Figure 2 There are four second strip grooves 211, two of which are arranged opposite each other along the first radial direction of the second sleeve 2, and the other two are arranged opposite each other along the second radial direction of the second sleeve 2. The first radial direction and the second radial direction of the second sleeve 2 are perpendicular to each other. In this optional embodiment, a second strip groove 211 is provided on the end face of the second protrusion 21 away from the other end of the second sleeve 2, which is radially arranged along the second sleeve 2. In this way, when it is necessary to screw the second sleeve 2 into the first sleeve 1, a tool can be inserted into the second strip groove 211 to drive the second sleeve 2 to rotate, which helps the second sleeve 2 to quickly enter the first sleeve 1 and improves the installation efficiency.

[0044] Optionally, such as Figure 3 and Figure 5 As shown, the portion of the inner hole of the first sleeve 1 near the first protrusion 11 is configured as a first guide hole 13, and the inner diameter of the first guide hole 13 gradually increases in the direction away from the other end of the first sleeve 1; and / or, the portion of the inner hole of the second sleeve 2 near the second protrusion 21 is configured as a second guide hole 24, and the inner diameter of the second guide hole 24 gradually increases in the direction away from the other end of the second sleeve 2.

[0045] Understandably, when disassembling the sleeve structure, the second sleeve 2 can be unscrewed first, and then the first sleeve 1 can be pulled out from the mounting hole 31 of the beam 3. Since there is no force point on the first sleeve 1 to pull it out, the second sleeve 2 can be screwed in a certain distance from the end where the first protrusion 11 of the first sleeve 1 is located. Then, the second protrusion 21 of the second sleeve 2 can be used as a force point. By holding the second protrusion 21, the second sleeve 2, together with the first sleeve 1, can be pulled out from the mounting hole 31 of the beam 3, thus completing the disassembly of the sleeve structure. The disassembly is simple and convenient. Based on this, in this optional embodiment, by setting the part of the inner hole of the first sleeve 1 near the first protrusion 11 as the first guide hole 13, and the inner diameter of the first guide hole 13 gradually increases along the direction away from the other end of the first sleeve 1, a guiding effect can be provided for the process of inserting the second sleeve 2 into the first sleeve 1 when disassembling the sleeve structure, which facilitates the quick insertion of the second sleeve 2 into the first sleeve 1 and improves the efficiency of disassembly.

[0046] In this optional embodiment, by setting the portion of the inner hole of the second sleeve 2 near the second protrusion 21 as the second guide hole 24, and by gradually increasing the inner diameter of the second guide hole 24 in the direction away from the other end of the second sleeve 2, the second guide hole 24 can provide guidance for the opponent during the insertion of the opponent into the second sleeve 2, making it easier to quickly install the opponent into the second sleeve 2 and improving the installation efficiency of the opponent.

[0047] like Figure 1 As shown, an embodiment of the present invention provides a vehicle body structural component, including a beam 3 and a sleeve structure as described above, wherein the sleeve structure passes through the mounting hole 31 of the beam 3.

[0048] Specifically, multiple beams 3 can be provided, and the multiple beams 3 are stacked sequentially. The mounting holes 31 of the multiple beams 3 are coaxially arranged. The first sleeve 1 can be inserted into the mounting holes 31 of the multiple beams 3, and the first protrusion 11 abuts against the lower side of the lowermost beam 3. The second sleeve 2 is inserted into the first sleeve 1, and the second protrusion 21 abuts against the upper side of the uppermost beam 3. The vehicle body structural components can be anti-collision beams, seat crossbeams, sill beams, etc., and there are no restrictions here.

[0049] In this embodiment, since the vehicle body structural component includes the aforementioned sleeve structure, it possesses all the beneficial effects brought about by all embodiments of the aforementioned sleeve structure, which will not be elaborated upon here.

[0050] This utility model provides a vehicle including the body structure components described above.

[0051] In this embodiment, since the vehicle includes the above-mentioned body structure components, it possesses all the beneficial effects brought about by all embodiments of the above-mentioned body structure components, which will not be described in detail here.

[0052] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
