DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] The connecting device and the vehicle provided by the utility model are described in detail below in conjunction with the embodiments.

[0025] See also Figure 1 and Figure 2 , Figure 1 It is a partial schematic diagram of an embodiment of the connection device of the present application; Figure 2 It is a partial cross-sectional schematic diagram of an embodiment of a connecting device of the present application. The present application provides a connecting device 10. The connecting device 10 includes a first connecting member 11 and a second connecting member 12. The first connecting member 11 includes a first connecting body 111 and at least one clamping member 112 disposed on the first connecting body 111. The number of clamping members 112 may be, but is not limited to, one, two, or more than three. The clamping member 112 is fixedly or detachably connected to the first connecting body 111. As in the present embodiment, the clamping member 112 is integrally formed on the first connecting body 111. The second connecting member 12 includes a second connecting body 121 and at least one clamping hole 122 disposed on the second connecting body 121. The number of clamping holes 122 may be, but is not limited to, one, two, or more than three. The number of clamping members 112 may correspond to the number of clamping holes 122. If the number of clamping members 112 is four, the number of clamping holes 122 is also four.

[0026] The connecting device 10 also includes at least one limiting portion 13. The number of limiting portions 13 may be, but is not limited to, one, two, or more than three. The number of limiting portions 13 may correspond to the number of the clamping members 112 and the number of the clamping holes 122. The limiting portion 13 is disposed on the second connecting body 121; at the same time, the limiting portion 13 is located on a side wall of the clamping hole 122. The limiting portion 13 is fixedly or detachably connected to the second connecting body 121. As in the present embodiment, the limiting portion 13 is integrally formed on the second connecting body 121. Among them, the clamping member 112 is clamped to the clamping hole 122 along the limiting portion 13; at the same time, the limiting portion 13 abuts against a side surface of the clamping member 112 facing the side wall of the hole.

[0027] Therefore, by providing the limiting portion 13 on a side wall of the clamping hole 122, not only can the clamping member 112 be firmly limited, reducing the risk of the clamping member 112 coming out of the clamping hole 122, but also the risk of deformation of the clamping member 112 can be reduced, thereby improving the strength of the clamping member 112. In addition, the limiting portion 13 is provided on the second connecting body 121, so that the mold structure of the first connecting member 11 is simple and operable, without considering the space limitation of the first connecting member 11, the mold limitation, etc.

[0028] See also Figures 3 to 5 , Figure 3 is a schematic diagram of α, L1 and L2 in an embodiment of the connection device of the present application; Figure 4 It is a partial structural diagram of the second connecting member and the limiting portion in an embodiment of the connecting device of the present application; Figure 5 1 is a partial structural diagram of the first connecting member in an embodiment of the connecting device of the present application. Figure 1 to Figure 2 In some embodiments, the engaging hole 122 includes a first hole side wall 1221 and a second hole side wall 1222 that are arranged opposite to each other. For example, the first hole side wall 1221 and the second hole side wall 1222 are arranged opposite to each other up and down, the first hole side wall 1221 is located at the upper part of the engaging hole 122, and the second hole side wall 1222 is located at the lower part of the engaging hole 122. The limiting portion 13 is located at the second hole side wall 1222. A guide surface 131 is obliquely arranged on the side of the limiting portion 13. The guide surface 131 has a guiding function. Among them, one end of the guide surface 131 away from the second hole side wall 1222 at least partially protrudes from the outer side wall of the second connecting member 12, so that the guide surface 131 in the limiting portion 13 is extended outward. The guide surface 131 of the above-mentioned limiting portion 13 can play a guiding function, which is conducive to the assembly of the engaging member 112 into the engaging hole 122, thereby improving the assembly efficiency of the connecting device 10.

[0029] In some embodiments, the angle between the guide surface 131 and the side surface of the clamping member 112 facing the second hole side wall 1222 is greater than 0 degrees and less than or equal to 60 degrees. The angle between the guide surface 131 and the side surface of the clamping member 112 facing the second hole side wall 1222 is defined as α. α is greater than 0 degrees and less than or equal to 60 degrees. By limiting the above α angle range, it is convenient for the clamping member 112 to be assembled into the clamping hole 122 along the guide surface 131, thereby improving the assembly efficiency of the connecting device 10. Among them, α can be but not limited to 1 degree, 5 degrees, 10 degrees, 13 degrees, 19 degrees, 25 degrees, 30 degrees, 33 degrees, 41 degrees, 45 degrees, 50 degrees, 54 degrees, 59 degrees and 60 degrees. It should be noted that when α is any of the above angles, when the clamping member 112 is clamped to the clamping hole 122 along the limiting portion 13, the limiting portion 13 needs to abut against the side surface of the clamping member 112 facing the side wall.

[0030] Specifically, α can be greater than or equal to 45 degrees and less than or equal to 60 degrees. α can be, but is not limited to, 45 degrees, 49 degrees, 50 degrees, 53 degrees, 55 degrees, and 60 degrees. By limiting the above α angle range, it is further convenient for the clamping member 112 to be assembled into the clamping hole 122 along the guide surface 131, thereby further improving the assembly efficiency and stability of the connecting device 10.

[0031] In some embodiments, one end of the limiting portion 13 away from the second hole side wall 1222 at least partially protrudes from the outer wall of the second connecting member 12, so that the limiting portion 13 at least partially extends to the outer wall of the second connecting member 12. The limiting portion 13 is inclined along the installation direction, which is more conducive to the clamping of the clamping member 112 in the clamping hole 122 along the limiting portion 13, thereby improving the assembly efficiency and stability of the connecting device 10.

[0032] When the installation direction is the left direction, the clamping member 112 is clamped in the clamping hole 122 along the left direction, wherein the limiting portion 13 protrudes from the outer side wall of the second connecting member 12 along the left direction. When the installation direction is the right direction, the clamping member 112 is clamped in the clamping hole 122 along the right direction, wherein the limiting portion 13 protrudes from the second connecting member 12 along the right direction. That is, the setting direction of the limiting portion 13 corresponds to the installation direction of the clamping member 112.

[0033] Please continue reading Figures 1 to 5 In some embodiments, a contact surface 132 is provided at the top of the limiting portion 13. One end of the contact surface 132 is connected to the guide surface 131. When the clamping member 112 is clamped in the clamping hole 122, the contact surface 132 abuts against a side surface of the clamping member 112 facing the second hole side wall 1222. The abutting surface 132 is in line contact or surface contact with a side surface of the clamping member 112 facing the second hole side wall 1222, and is used to abut against the clamping member 112, reduce the risk of the clamping member 112 coming out, and thereby improve the connection strength of the connecting device 10.

[0034] In some embodiments, the top of the limiting portion 13 includes a cutting surface 133. The cutting surface 133 is connected to the end of the abutting surface 132 away from the guide surface 131. The cutting surface 133 can reduce the risk of the tip of the limiting portion 13 being too sharp and the mold tip, thereby improving the safety performance of the second connecting member 12.

[0035] In some embodiments, the extension length of the limiting portion 13 on the side wall of the hole is less than or equal to the extension length of the snap-in hole 122 along the side wall of the hole, which not only firmly limits the snap-in component 112 and reduces the risk of the snap-in component 112 escaping from the snap-in hole 122; but also improves the assembly efficiency of the connecting device 10.

[0036] In some embodiments, the limiting portion 13 includes a guide surface 131 and an outer side surface 134 that are arranged opposite to each other. The ratio between the vertical distance between the guide surface 131 and the outer side surface 134 and the thickness of the second connecting body 121 is greater than or equal to 0.3 and less than 1. The vertical distance between the guide surface 131 and the outer side surface 134 is defined as L1, the thickness of the second connecting body 121 is defined as L2, and the ratio between the vertical distance between the guide surface 131 and the outer side surface 134 and the thickness of the second connecting body 121 is defined as S. S=L1 / L2. S is greater than or equal to 0.3 and less than 1. For example, S can be, but is not limited to, 0.3, 0.4, 0.43, 0.5, 0.54, 0.6, 0.66, 0.7, 0.76, 0.8, 0.83, 0.9, 0.97, etc. By limiting the size of S, not only the strength of the limiting portion 13 can be improved, but also the mold of the first connecting member 11 can be simplified.

[0037] Specifically, S is greater than or equal to 0.5 and less than or equal to 0.8. For example, S may be, but is not limited to, 0.5, 0.53, 0.64, 0.68, 0.73, and 0.8. For example, in this embodiment, when the thickness of the second connecting body 121 is 2.5 mm, the vertical distance L1 between the guide surface 131 and the outer surface 134 may be, but is not limited to, 1.5 mm and 2 mm.

[0038] In some embodiments, the first connecting member 11 further includes at least one cantilever beam 113. The cantilever beam 113 is disposed between the first connecting body 111 and the clamping member 112. The number of cantilever beams 113 may correspond to the number of clamping members 112. The cantilever beam 113 is fixedly or detachably connected between the first connecting body 111 and the clamping member 112. As in the present embodiment, the cantilever beam 113 is integrally formed between the first connecting body 111 and the clamping member 112. The cantilever beam 113 can not only increase the extension length of the clamping member 112, so that the clamping member 112 has a certain elasticity, but also meet the strength of the clamping member 112.

[0039] Compared with the prior art, the connection device 10 of the present application includes a first connection member 11, a second connection member 12 and at least one limiting portion 13. The first connection member 11 includes a first connection body 111 and at least one clamping member 112 arranged on the first connection body 111. The second connection member 12 includes a second connection body 121 and at least one clamping hole 122 arranged on the second connection body 121. At least one limiting portion 13 is arranged on the second connection body 121 and is located on a side wall of the clamping hole 122. The clamping member 112 is clamped to the clamping hole 122 along the limiting portion 13, and the limiting portion 13 abuts against a side surface of the clamping member 112 facing the side wall of the hole. By arranging the limiting portion 13 on a side wall of the clamping hole 122, not only can the clamping member 112 be firmly limited, reducing the risk of the clamping member 112 escaping from the clamping hole 122; but also the risk of deformation of the clamping member 112 can be reduced, and the strength of the clamping member 112 can be improved. In addition, the limiting portion 13 is disposed on the second connecting body 121 , so that the mold structure of the first connecting member 11 is simple and operable, without considering space limitations and mold limitations of the first connecting member 11 .

Through the above-mentioned connecting device 10, the vehicle can not only firmly limit the clamping member 112 and reduce the risk of the clamping member 112 escaping from the clamping hole 122; but also reduce the risk of deformation of the clamping member 112 and improve the strength of the clamping member 112. In addition, the limiting portion 13 is arranged on the second connecting body 121, so that the mold structure of the first connecting member 11 is simple and the operability is strong, and there is no need to consider the space limitation of the first connecting member 11, the mold limitation, etc.

[0041] The first connecting member 11 in the connecting device 10 may be, but not limited to, a first pillar trim (not shown in the figure). The second connecting member 12 may be, but not limited to, a second pillar trim (not shown in the figure).
