[0037] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] like Figure 1As shown, in one embodiment, a connection device 100 is used to connect a first target object and a second target object together, wherein the connection device 100 includes a connection module 10 and an assembly module 20, wherein the connection module 10 can be installed on the first target object, and the assembly module 20 can be installed on the second target object. When in use, the connection module 10 can be first installed on the first target object, and the assembly module 20 can be installed on the second target object, and then the connection module 10 and the assembly module 20 can be connected together, so that the first target object and the second target object can be connected together.

[0039] like Figure 1 and Figure 2 As shown, the connection module 10 includes a support component 1, a connection component 2 and a limit component 3; the support component 1 is used to connect the first target object; the connection component 2 is installed on the support component 1 and can move relative to the support component 1 so as to cooperate with the assembly module 20 on the second target object, thereby realizing the connection between the connection module 10 and the assembly module 20; the limit component 3 cooperates with the support component 1 to limit the connection component 2 on the support component 1, so that the support component 1, the connection component 2 and the limit component 3 become one, and when the support component 1 is connected to the first target object, the connection component 2 and the limit component 3 will not fall off from the first target object.

[0040] When there are multiple connection points between the first target object and the second target object, the first target object and the second target object can be connected by multiple connection devices 100, wherein one connection device 100 connects the first target object and the second target object at one connection point. In addition, one connection point includes a first connection area located on the first target object and a second connection area located on the second target object. When one connection device 100 connects the first target object and the second target object at one connection point, the connection module 10 of the connection device 100 is installed in the first connection area of ​​the connection point, and the assembly module 20 of the connection device 100 is installed in the second connection area of ​​the connection point. "Multiple" means greater than or equal to two, and the word "multiple" has the same meaning in each embodiment and will not be repeated in the following text.

[0041] When multiple connecting devices 100 are used to connect a first target object and a second target object, the connecting modules 10 of each connecting device 100 can be first installed in the corresponding first connecting area of ​​the first target object, and the connecting modules 10 of each connecting device 100 can be installed in the corresponding second connecting area of ​​the second target object, wherein the operation of installing the connecting module 10 on the first target object and the operation of installing each assembly module 20 on the second target object can be performed simultaneously at different workstations to improve production efficiency.

[0042] Subsequently, when assembling the connection component 2 and the assembly module 20, since after the connection module 10 is connected to the first target object, the connection component 2 can be retained on the first target object, and the second assembly can be retained on the second target object, when aligning the first target object with the second target object, it is possible to use one assembly tool to simultaneously drive each connection component 2 to move, so that each connection component 2 can cooperate with the corresponding assembly module 20 respectively, thereby further improving production efficiency.

[0043] In an actual scenario, the connection device 100 can be applied to a vehicle to connect two parts on the vehicle. For example, the connection device 100 can be used to connect the body and chassis of the vehicle. At this time, one of the first target object and the second target object is the body, and the other is the chassis. There are usually multiple connection points between the body and the chassis, and the above-mentioned connection device 100 can be used at each connection point to connect the body and the chassis. Compared with the prior art method of connecting the body and the chassis at one connection point at a time with a threaded connector, the connection device 100 of this embodiment can achieve the purpose of improving the assembly efficiency of the body and the chassis.

[0044] In one embodiment, the connection component 2 and the assembly module 20 are detachably connected. Before the connection device 100 is used, the connection component 2 and the assembly module 20 can be matched together, so that the connection device 100 can be integrated together, which is convenient for the storage of the connection device 100 and effectively avoids the loss of parts. When using the connection device 100, the connection component 2 and the assembly module 20 can be disassembled first, so that the assembly module 20 and the connection module 10 are separated, and then the two are installed on two target objects respectively.

[0045] like Figure 2 As shown, in one embodiment, the support component 1 has a first surface 11 and a second surface 12 that are arranged opposite to each other, and a mounting hole 13 is also provided on the support component 1, and the mounting hole 13 runs through the first surface 11 to the second surface 12; the connecting component 2 is passed through the mounting hole 13, and can move along the axial direction of the mounting hole 13, so as to cooperate with the assembly module 20; a resisting structure 14 is provided on the hole wall of the mounting hole 13, and when the connecting component 2 moves toward the first surface 11, it can conflict with the resisting structure 14; when the connecting component 2 moves toward the second surface 12, it can conflict with the limiting component 3. Among them, "moving toward the first surface" means moving in the direction from the second surface to the first surface; "moving toward the second surface" means moving in the direction from the first surface to the second surface.

[0046] That is, the connection component 2 can be limited in the radial direction of the installation hole 13 by the hole wall of the installation hole 13, and the connection component 2 can be limited in the axial direction of the installation hole 13 by the resisting structure 14 and the limiting component 3.

[0047] In addition, the mounting hole 13 can also guide the axial movement of the connecting component 2 along the mounting hole 13 , so that the connecting component 2 can cooperate with the assembly module 20 more accurately.

[0048] In addition, when the connecting component 2 cooperates with the assembly module 20, the first surface 11 is opposite to the assembly module 20. At this time, the first surface 11 is located between the assembly module 20 and the second surface 12. In addition, the connecting component 2 cooperates with the assembly module 20 after passing through the mounting hole 13 from the first surface 11. This avoids the interference of the hole wall of the mounting hole 13 when the assembly module 20 cooperates with the connecting component 2, which is more conducive to the cooperation between the two.

[0049] like Figure 2 As shown, in one embodiment, the mounting hole 13 is a stepped hole. Along the direction from the first surface 11 to the second surface 12, the mounting hole 13 includes a first hole and a second hole arranged in sequence. The first hole and the second hole are connected, and the aperture of the first hole is smaller than the aperture of the second hole so that a step surface is formed between the two, and the step surface is the above-mentioned retaining structure 14.

[0050] In addition, the first hole can be used to guide the movement of the connection component 2 along the axis of the mounting hole 13. After the connection module 10 is assembled, a portion of the connection component 2 is located in the first hole, and another portion is located in the second hole.

[0051] like Figure 2 As shown, in one embodiment, the support assembly 1 includes a first shell 15, a second shell 16 and a first elastic member 17; the first shell 15 and the second shell 16 are spaced apart; the first shell 15 can be connected to the assembly module 20 through the connecting assembly 2, and the second shell 16 is used to connect to the first target object; the first elastic member 17 is arranged between the first shell 15 and the second shell 16, and is used to buffer the relative movement of the first shell 15 and the second shell 16. When the first shell 15 is connected to the second assembly module 20 through the connecting assembly 2, the second shell 16 can be spaced apart from the second assembly module 20.

[0052] The one of the first shell 15 and the second shell 16 connected to the assembly module 20 through the connection component 2 is equivalent to being connected to the second target object, so when the first target object moves relative to the second target object, the relative movement between the first target object and the second target object can be buffered by the first elastic member 17. When the connecting device 100 is used to connect the vehicle body and the chassis, the support component 1 can play a role in vibration reduction, thereby improving the riding comfort.

[0053] like Figure 2 As shown, the second shell 16 is sleeved on the first shell 15, so that the support assembly 1 can be more integrated.

[0054] like Figure 2 As shown, the mounting hole 13 is actually arranged on the first shell 15, wherein the first surface 11 and the second surface 12 are both surfaces of the first shell 15. In addition, the second shell 16 is provided with a receiving hole 161, which penetrates the second shell 16 along the direction from the first surface 11 to the second surface 12, the first shell 15 is arranged in the receiving hole 161, and the first elastic member 17 can also be arranged in the receiving hole 161.

[0055] In one embodiment, one end of the first shell 15 having the first surface 11 passes through the second shell 16, and when the first shell 15 is connected to the second assembly module 20 through the connecting component 2, the end of the first shell 15 having the first surface 11 can interfere with the assembly module 20. At this time, the first surface 11 is in contact with the assembly module 20.

[0056] In one embodiment, the axis of the receiving hole 161 and the axis of the mounting hole 13 may be arranged in parallel, and further, the receiving hole 161 and the mounting hole 13 may be arranged coaxially. In addition, in the radial direction of the receiving hole 161, a first elastic member 17 is provided between the first shell 15 and the second shell 16; in the axial direction of the receiving hole 161, a first elastic member 17 is also provided between the first shell 15 and the second shell 16.

[0057] In one embodiment, the first elastic member 17 is filled between the first shell 15 and the second shell 16, wherein the first elastic member 17 may be elastic rubber or the like. In addition, the first shell 15, the second shell 16 and the elastic rubber may be integrally provided, for example, the three may be prepared together using a sagging rubber process. Of course, in other embodiments, the elastic rubber may also be replaced with an elastic material such as silicone, or the first elastic member 17 may also be a spring or the like.

[0058] like Figure 2 As shown, in one embodiment, a flange 162 is provided on the outer surface of the second housing 16, and the flange 162 is used to connect with the first target object, wherein the flange 162 and the first target object can be connected together by a threaded connector, etc. Of course, the flange 162 and the first target object can also be connected together by welding or riveting.

[0059] In one embodiment, the connection component 2 is threadedly matched with the assembly module 20. Specifically, in one achievable implementation, the connection component 2 has a stud 21, and the assembly module 20 has a threaded hole, and the stud 21 cooperates with the threaded hole to achieve threaded matching between the connection component 2 and the assembly module 20, wherein the stud 21 and the mounting hole 13 may be coaxially arranged. In another achievable implementation, in order to achieve threaded matching between the connection component 2 and the assembly module 20, the connection component 2 may have a threaded hole, and the assembly module 20 may have a stud 21.

[0060] like Figure 2 and Figure 3 As shown, in one embodiment, the limit assembly 3 includes a base 31, which is connected to the support assembly 1; an avoidance hole 311 is provided in the area of ​​the base 31 opposite to the mounting hole 13, and the avoidance hole 311 penetrates the base 31 along the axial direction of the mounting hole 13, so that the connecting assembly 2 can receive external force at the avoidance hole 311 and move along the axial direction of the mounting hole 13 to cooperate with the assembly module 20.

[0061] The “area where the base 31 is opposite to the mounting hole 13” may refer to the area where the orthographic projection of the base 31 on the first plane can overlap with the orthographic projection of the mounting hole 13 on the first plane, that is, the orthographic projection of the area where the base 31 is opposite to the mounting hole 13 on the first plane overlaps with the orthographic projection of the mounting hole 13 on the first plane. In addition, the base 31 may be threadedly matched with the support assembly 1. Specifically, the base 31 may be threadedly matched with the first shell 15, wherein an external thread is provided on the outer surface of one end of the first shell 15 close to the second surface 12, and the base 31 has an assembly hole, which is a threaded hole, and the assembly hole is threadedly matched with one end of the first shell 15 close to the second surface 12. In addition, the assembly hole is a blind hole, and the bottom wall of the assembly hole is opposite to the mounting hole 13, and the avoidance hole 311 is provided on the bottom surface of the assembly hole and passes through the bottom wall of the assembly hole.

[0062] The assembly tool can apply force to the connection component 2 at the avoidance hole 311, so that it moves along the axial direction of the mounting hole 13, so as to achieve cooperation with the assembly module 20. When the connection component 2 can rotate around the axis of the mounting hole 13, the assembly tool also applies force to the connector from the avoidance hole 311, so that it can move along the axial direction of the mounting hole 13 and rotate around the axis of the mounting hole 13. In addition, when the connection component 2 moves from the first surface 11 to the second surface 12, the connection component 2 can contact the base 31 to prevent the connection component 2 from exiting the mounting hole 13.

[0063] like Figures 2 to 4As shown, in one embodiment, a first limiting structure 22 is provided on the connecting component 2, and a second limiting structure 32 is provided on at least one of the supporting component 1 and the limiting component 3; the first limiting structure 22 and the second limiting structure 32 can switch between a mating state and a staggered state; wherein, when the first limiting structure 22 and the second limiting structure 32 are in a mating state, the first limiting structure 22 can limit the connecting component 2 to prevent the connecting component 2 from rotating around its own axis relative to the supporting component 1; when the first limiting structure 22 and the second limiting structure 32 are in a staggered state, the connecting component 2 can rotate around its own axis relative to the supporting component 1 so as to be threadedly mated with the assembly module 20.

[0064] During assembly, the first limiting structure 22 and the second limiting structure 32 can be in a staggered state, so that the connecting component 2 and the assembly module 20 can be threadedly matched, thereby connecting the first target object and the second target object together; when the assembly is completed, the first limiting structure 22 and the second limiting structure 32 can be in a matched state to prevent the connection component 2 and the assembly module 20 from loosening, thereby making the connection between the first target object and the second target object more firmly.

[0065] In addition, the axis of the connecting component 2 may be parallel to the axis of the mounting hole 13. Further, the connecting component 2 and the mounting hole 13 may be coaxially arranged. In addition, the axis of the connecting component 2 is the axis of the stud 21 of the connecting component 2.

[0066] like Figure 2 As shown, in one embodiment, along the axis of the connecting component 2, the connecting component 2 includes a first connecting member 23 and a second connecting member 24; the first connecting member 23 is used to threadably cooperate with the assembly module 20, and the first limiting structure 22 is arranged on the second connecting member 24; wherein, the second connecting member 24 can drive the first connecting member 23 to rotate around the axis of the connecting component 2, so that the first connecting member 23 and the assembly module 20 are threadably cooperated; that is, the assembly tool can apply torque to the second connecting member 24, and then drive the first connecting member 23 to rotate through the second connecting member 24. In addition, the stud 21 of the above-mentioned connecting component 2 can be a part of the structure of the first connecting member 23. In addition, along the axis of the connecting component 2, the arrangement direction from the first connecting member 23 to the second connecting member 24 is the arrangement direction from the first surface 11 to the second surface 12.

[0067] The second connecting member 24 can move relative to the first connecting member 23 along the axis of the connecting assembly 2 to switch between the first position and the second position; wherein, when the second connecting member 24 is in the first position, the first limiting structure 22 and the second limiting structure 32 are in a staggered state; when the second connecting member 24 is in the second position, the first limiting structure 22 and the second limiting structure 32 are in a mating state; in addition, a first retaining structure 14 is provided on the first connecting member 23, and a second retaining structure 14 is provided on the second connecting member 24, and the first retaining structure 14 and the second retaining structure 14 cooperate with each other so as to prevent the first connecting member 23 from rotating relative to the second connecting member 24 when the second connecting member 24 is in the first position and the second position.

[0068] In one embodiment, the direction from the first surface 11 to the second surface 12 is the direction from the first position to the second position. That is, when the second connecting member 24 moves from the second position to the first position, it actually moves along the direction from the second surface 12 to the first surface 11; when the second connecting member 24 moves from the first position to the second position, it actually moves along the direction from the first surface 11 to the second surface 12. In addition, the first connecting member 23 and the second connecting member 24 are both located in the mounting hole 13, wherein "the first connecting member 23 and the second connecting member 24 are both located in the mounting hole 13" specifically means that at least a portion of the first connecting member 23 is located in the mounting hole, and at least a portion of the second connecting member 24 is located in the mounting hole 13.

[0069] like Figure 2 As shown, in one feasible embodiment, the first connecting member 23 is provided with a connecting column 25, the second connecting member 24 is provided with a connecting hole 26, and the connecting column 25 is located in the connecting hole 26; the first retaining structure 14 is a flat part set on the side of the connecting column 25, and the second retaining structure 14 is a flat part set on the inner surface of the connecting hole 26. In another feasible embodiment, the first connecting member 23 is provided with a connecting hole 26, the second connecting member 24 is provided with a connecting column 25, and the connecting column 25 is located in the connecting hole 26; the first retaining structure 14 is a flat part set on the inner surface of the connecting hole 26, and the second retaining structure 14 is a flat part set on the side of the connecting column 25. Among them, the connecting column 25 can be a regular hexagonal prism, and the connecting hole 26 can be a regular hexagonal hole.

[0070] In addition, the connecting hole 26 is a blind hole, and the connecting column 25 can be in contact with the bottom surface of the connecting hole 26, so that when the second connecting member 24 moves to a certain position relative to the first connecting member 23 along the axial direction of the connecting component 2, the connecting column 25 can be in contact with the bottom surface of the connecting hole 26, thereby enabling the second connecting member 24 to drive the first connecting member 23 to move along the axial direction of the connecting component 2.

[0071] In addition, when the first connecting member 23 is provided with a connecting column 25, the connecting column 25 is connected to the connecting column 25 and the stud 21 of the above-mentioned connecting component 2, wherein the stud 21 can be arranged on the surface of the connecting column 25 away from the second connecting member 24, and the stud 21 and the connecting column 25 are arranged along the direction from the first surface 11 to the second surface 12, the stud 21 and the connecting column 25 can be coaxially arranged, and the two can be arranged as one body.

[0072] The first connecting member 23 further includes a protrusion 27 (refer to Figure 2 ), the protrusion 27 is arranged on the outer side of the connecting column 25 or the stud 21, when the second connecting member 24 drives the first connecting member 23 to move toward the first surface 11 (that is, the connecting assembly 2 moves toward the first surface 11), the protrusion 27 can contact with the blocking structure 14 (that is, the protrusion 27 can contact with the step surface of the mounting hole), so as to prevent the first connecting member 23 from completely withdrawing from the mounting hole 13 from the first surface 11. In addition, the end of the connecting column 25 away from the stud 21 extends into the connecting hole 26, and the end of the stud 21 away from the connecting column 25 is threadedly engaged with the assembly module 20.

[0073] When the second connecting member 24 moves toward the second surface 12, the second connecting member 24 can collide with the base 31 to prevent the second connecting member 24 from completely withdrawing from the mounting hole 13 at the second surface 12. Since the connecting column 25 can collide with the bottom surface of the connecting hole 26 when the first connecting member 23 moves toward the second surface 12, the second connecting member 24 can be prevented from completely withdrawing from the mounting hole 13 at the second surface 12, thereby preventing the first connecting member 23 from completely withdrawing from the mounting hole 13 at the second surface 12. In addition, a portion of the second connecting member 24 can extend out of the mounting hole 13 from the avoidance hole 311 of the base 31, and this portion can pass through the base 31 to protrude from the surface of the base 31 away from the first surface 11.

[0074] like Figure 2As shown, in one embodiment, along the axial direction of the connecting component 2, the second connecting member 24 includes a first connected first cylinder 241 and a second cylinder 242, wherein the diameter of the first cylinder 241 is greater than the diameter of the second cylinder 242, and a step surface is formed between the two. The first limiting structure 22 is arranged on the outer side of the first cylinder 241, and the connecting hole 26 is arranged on the surface of the first cylinder 241 away from the second cylinder 242. When the second connecting member 24 is in the second position, the first cylinder 241 can be against the base 31, and the second cylinder 242 can be extended from the avoidance hole 311 to the mounting hole 13. In addition, the second cylinder 242 can be provided with a flat position to cooperate with the assembly tool, and further, the second cylinder 242 can be a regular hexagonal prism, and the diameter of the second cylinder 242 is its equivalent diameter. In addition, the first cylinder 241 and the second cylinder 242 can be coaxially arranged. The axial direction of the connecting component 2 is the axis of the connecting component 2.

[0075] like Figure 2 As shown, in one embodiment, the connecting component 2 also includes a second elastic member 28, and the second elastic member 28 is connected to the second connecting member 24. Initially, the second connecting member 24 is in the second position. When an external force drives the second connecting member 24 to move from the second position to the first position, the second connecting member 24 can apply force to the second elastic member 28 so as to elastically deform the second elastic member 28; when the external force is removed, the second connecting member 24 can be reset from the first position to the second position under the action of the deformation force of the second elastic member 28, which makes it easier for the first limiting structure 22 to cooperate with the second limiting structure 32.

[0076] like Figure 2 As shown, in one embodiment, the second elastic member 28 is arranged between the resisting structure 14 and the second connecting member 24; the second elastic member 28 is a spring, and the second elastic member 28 is sleeved on the first connecting member 23; that is, the second elastic member 28 is arranged between the step surface of the mounting hole 13 and the second connecting member 24, and when the second connecting member 24 moves toward the side of the first surface 11, it can compress the second elastic member 28 so as to cause the second elastic member 28 to produce elastic deformation.

[0077] like Figure 2 As shown, in one embodiment, the connecting assembly 2 further includes a gasket 29, which is sleeved on the first connecting member 23 and disposed between the second elastic member 28 and the second connecting assembly 2, so as to facilitate the rotation of the second connecting member 24.

[0078] like Figure 2As shown, in one embodiment, the limiting assembly 3 includes a limiting member 33, and the second limiting structure 32 is arranged on the limiting member 33; the limiting member 33 is connected to the supporting assembly 1, and can swing around the axis of the connecting assembly 2, and the swing angle of the limiting member 33 around the axis of the connecting assembly 2 is greater than 0 degrees and less than 360 degrees. In actual operation, when the phase of the second connecting member 24 relative to the limiting member 33 (i.e., the relative position of the two in the circumferential direction of the mounting hole 13) is not appropriate, it is difficult to make the first limiting structure 22 and the second limiting structure 32 cooperate when the second connecting member 24 moves along the axial direction of the connecting assembly 2, and the limiting member 33 is arranged to be able to swing around the axis of the connecting assembly 2, so that the relative positions of the limiting member 33 and the second connecting member 24 in the circumferential direction of the mounting hole 13 can be easily adjusted, so as to facilitate the cooperation of the first limiting structure 22 and the second limiting structure 32 after the first connecting member 23 cooperates with the assembly module 20.

[0079] In addition, if Figure 2 As shown, the limiting component 3 further includes a third elastic member 34 , and the limiting component 33 is connected to the supporting component 1 via the third elastic member 34 ; when the limiting component 33 swings around the axis of the connecting component 2 , the third elastic member 34 can generate elastic deformation.

[0080] In addition, when the support assembly 1 is provided with the above-mentioned mounting hole 13, the limiting assembly 3 and the third elastic member 34 are both arranged in the mounting hole 13. Moreover, when the limiting assembly 3 also has a base 31, the limiting member 33 is arranged in the mounting hole 13 and can contact the base 31 so as to support the limiting member 33 through the base 31.

[0081] like Figure 3 and Figure 4 As shown, in one embodiment, the first limiting structure 22 includes a plurality of first meshing teeth 221 disposed on the side of the second connecting member 24, and each first meshing tooth 221 is evenly arranged around the axis of the second connecting member 24; the limiting member 33 is a limiting ring, and the second limiting structure 32 includes a plurality of second meshing teeth 321 disposed on the inner surface of the limiting ring, and each second meshing tooth 321 is evenly arranged around the axis of the limiting ring; when the second connecting member 24 is located in the second position, each first meshing tooth 221 is located between a group of two adjacent second meshing teeth 321, and one first meshing tooth 221 can be accommodated between two adjacent second meshing teeth 321, so that the arrangement is more conducive to the cooperation between the first limiting structure 22 and the second limiting structure 32. Among them, the axis of the second connecting member 24 is the axis of the connecting assembly 2.

[0082] The gap between two adjacent second meshing teeth 321 is defined as an accommodating gap. One first meshing tooth 221 can be accommodated in one accommodating gap. When the second connecting member 24 is located at the second position and rotates around its own axis, one first meshing tooth 221 can conflict with the second meshing teeth 321 on both sides of the accommodating gap.

[0083] like Figure 2 As shown, in one embodiment, the first connecting member 23, the second limiting member 33 and the limiting ring are all arranged in the mounting hole 13; when the second connecting member 24 is located in the first position, the first limiting member 33 is located on the side of the second limiting member 33 away from the second surface 12; the first meshing tooth 221 has a first guide surface, and when the second connecting member 24 is located in the second position, the first guide surface is adjacent to the second meshing tooth 321, and the first guide surface extends from the end surface of the first meshing tooth 221 close to the second surface 12 to the first surface 11, and along the direction from the first surface 11 to the second surface 12, the first guide surface gradually moves away from the second meshing tooth 321 adjacent thereto. This makes it easier for the first meshing tooth 221 to enter the accommodation gap. In addition, a first meshing tooth 221 has two first guide surfaces. In the circumferential direction of the mounting hole 13, the two first guide surfaces of a first meshing tooth 221 are respectively located on both sides of the first meshing tooth 221. When the first meshing tooth 221 is located in the accommodating gap, the two first guide surfaces are respectively adjacent to the two second meshing teeth 321 on both sides of the accommodating gap (the accommodating gap is formed between the two second meshing teeth 321). Specifically, the two first guide surfaces are defined as guide surface a and guide surface b, respectively. When the first meshing tooth 221 is located in the accommodating gap, the two second meshing teeth 321 on both sides of the accommodating gap are defined as meshing tooth a and meshing tooth b, respectively, wherein guide surface a is adjacent to meshing tooth a, and guide surface b is adjacent to meshing tooth b.

[0084] like Figure 5 As shown, the second meshing tooth 321 has a second guide surface 322. When the second connecting member 24 is located at the second position, the second guide surface 322 is adjacent to the second meshing tooth 321. The second guide surface 322 extends from the end surface of the second meshing tooth 321 close to the first surface 11 to the second surface 12, and along the direction from the first surface 11 to the second surface 12, the second guide surface 322 gradually approaches the first meshing tooth 221 adjacent thereto. This makes it easier for the first meshing tooth 221 to enter the accommodation gap. In addition, one second meshing tooth 321 has two second guide surfaces 322. In the circumferential direction of the mounting hole 13, the two second guide surfaces 322 of one second meshing tooth 321 are respectively located on both sides of the second meshing tooth 321.

[0085] like Figure 1 and Figure 2As shown, in one embodiment, the assembly module 20 includes a connecting plate 4 and an assembly part 5; the connecting plate 4 is used to connect the second target object; the assembly part 5 is installed on the connecting plate 4 and is used to cooperate with the connecting component 2; one of the assembly part 5 and the connecting component 2 is provided with an assembly hole 51, and when the connecting component 2 cooperates with the assembly module 20, the other of the assembly part 5 and the connecting component 2 is penetrated through the assembly hole 51; at least one of the assembly part 5 and the connecting component 2 can move relative to the connecting plate 4 in the radial direction of the assembly hole 51. Such a configuration is more conducive to the assembly part 5 or the connecting component 2 being passed into the assembly hole 51.

[0086] Specifically, in Figure 2 In the illustrated embodiment, the assembly hole 51 is provided on the assembly part 5, and when the connecting component 2 is matched with the assembly module 20, the connecting component 2 is passed through the assembly hole 51. When the connecting component 2 is threadedly matched with the assembly component, the assembly hole 51 is a threaded hole provided on the assembly part 5, and the stud 21 of the first connecting member 23 is passed through the assembly hole 51 and threadedly matched with the assembly hole 51.

[0087] In this mode, a positioning space 41 is provided on the connection plate 4, and the assembly part 5 is arranged in the positioning space 41 and can move relative to the connection plate 4 in the radial direction of the assembly hole 51 in the positioning space 41. Among them, a window 42 is provided on the connection plate 4, and the window 42 penetrates the connection plate 4 along the direction from the first surface 11 to the second surface 12, and the window 42 is connected with the positioning space 41, and the window 42 is opposite to the assembly hole 51. The connection component 2 passes through the window 42 and enters the assembly hole 51. In addition, when the assembly part 5 moves to the maximum position in the positioning space 41 along the radial direction of the assembly hole 51, the assembly hole 51 is still opposite to the window 42. In this mode, it can be that only the assembly part 5 can move relative to the connection plate 4 in the radial direction of the assembly hole 51.

[0088] like Figure 2 As shown, the positioning space 41 can be a blind hole arranged on the surface of the connecting plate 4 facing away from the supporting assembly 1 , and the window 42 is arranged on the bottom surface of the positioning space 41 and penetrates to the surface of the connecting plate 4 close to the supporting assembly 1 .

[0089] In addition, the end of the connecting component 2 used for cooperating with the assembly part 5 (i.e., the end of the connecting component 2 facing away from the second surface 12) is provided with a first guide portion to guide the connecting component 2 into the assembly hole 51. Of course, the end of the assembly hole 51 close to the support component 1 may also be provided with a second guide portion to guide the connecting component 2 into the assembly hole 51. The first guide portion may be a tapered portion, and the first guide portion may be a part of the stud 21, which is the end of the stud 21 facing away from the second surface 12, wherein the cross-sectional radius of the first guide portion gradually increases along the direction from the first surface 11 to the second surface 12. The second guide portion may be a tapered hole, and the cross-sectional radius of the second guide portion gradually decreases along the direction from the second surface 12 to the first surface 11.

[0090] It should be understood that the above corresponding settings can be replaced by other methods, such as:

[0091] In other embodiments, the connection component 2 and the assembly module 20 may also be connected together by riveting or other methods.

[0092] In other embodiments, the assembly hole 51 may also be provided on the connecting component 2. When the connecting component 2 cooperates with the assembly module 20, the assembly part 5 is passed through the assembly hole 51. At this time, the assembly part 5 is a bolt structure, and a threaded hole is provided on the connecting component.

[0093] In other embodiments, in addition to the assembly member 5 being able to move in the radial direction of the assembly hole 51, the connection component 2 can also move relative to the connection plate 4 in the radial direction of the assembly hole 51. Alternatively, only the connection component 2 can move relative to the connection plate 4 in the radial direction of the assembly hole 51.

[0094] In other embodiments, the second elastic member 28 may also be disposed between the second connecting member 24 and the base 31 , and when the second connecting member 24 moves toward the first surface 11 , the second elastic member 28 can be stretched so as to cause elastic deformation of the second elastic member 28 .

[0095] In other embodiments, the first shell 15 may also be disposed on the outside of the second shell 16 , and the two are connected together via a first elastic connection.

[0096] In other embodiments, in order to facilitate the first meshing tooth 221 to enter the accommodating gap, only the first meshing tooth 221 may be provided with the first guide surface, or only the second meshing tooth 321 may be provided with the second guide surface 322 .

[0097] An embodiment of the present invention further provides a vehicle, which includes the connection device 100 described in any one of the above embodiments.

[0098] The vehicle further includes a body and a chassis, and the body and the chassis can be connected together through a connecting device 100. In addition, when the connecting device 100 is used to connect the body and the chassis, the vehicle has a plurality of connecting devices 100, and the connecting module 10 of each connecting device 100 is installed on the chassis, and the assembly module 20 of each connecting device 100 is installed on the body.

[0099] Specifically, the connecting plate 4 can be installed on the surface of the vehicle body close to the chassis (that is, installed on the lower surface of the vehicle body). In this case, the vehicle body can close the opening of the positioning space 41 on the surface of the connecting plate 4 away from the supporting assembly 1, so as to encapsulate the assembly part 5 in the positioning space 41. In addition, the distance between the vehicle body and the bottom surface of the positioning space 41 is greater than the axial height of the assembly part 5 in the assembly hole 51, so that after the connecting plate 4 is connected to the vehicle body, the assembly part 5 can move along the radial direction of the assembly hole 51.

[0100] It should be understood that when multiple connecting devices 100 are used to connect the vehicle body and the chassis, the connecting modules 10 of each connecting device 100 can also be installed on the vehicle body. In this case, the assembly modules 20 of each connecting device 100 are installed on the chassis.

[0101] It should be understood that the connecting device 100 can also be used to connect other parts of a vehicle. In addition, the connecting device 100 can be used to connect two parts on a vehicle, and it can also be used for any other two objects.

[0102] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0103] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
