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

[0038] As Figure 1As shown in the drawings, in an embodiment, the connecting device 100 is used to connect a first target object and a second target object together, wherein the connecting device 100 comprises a connecting module 10 and an assembling module 20, the connecting module 10 is capable of being installed on the first target object, and the assembling module 20 is capable of being installed on the second target object. In use, the connecting module 10 can be installed on the first target object first, and the assembling module 20 can be installed on the second target object, and then the connecting module 10 and the assembling module 20 are connected together, so as to realize the connection of the first target object and the second target object together.

[0039] As shown in the drawings, Figure 1 and Figure 2 The connecting module 10 comprises a supporting assembly 1, a connecting assembly 2 and a limiting assembly 3; the supporting assembly 1 is used to connect the first target object; the connecting assembly 2 is installed on the supporting assembly 1 and is capable of moving relative to the supporting assembly 1, so as to cooperate with the assembling module 20 on the second target object, and then realize the connection of the connecting module 10 and the assembling module 20; the limiting assembly 3 cooperates with the supporting assembly 1 to limit the connecting assembly 2 on the supporting assembly 1, so that the supporting assembly 1, the connecting assembly 2 and the limiting assembly 3 become an integral whole, when the supporting assembly 1 is connected with the first target object, the connecting assembly 2 and the limiting assembly 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, multiple connecting devices 100 can be used to connect the first target object and the second target object, wherein one connecting device 100 connects the first target object and the second target object at one connection point. In addition, one connection point comprises a first connecting area on the first target object and a second connecting area on the second target object, when one connecting device 100 connects the first target object and the second target object at one connection point, the connecting module 10 of the connecting device 100 is installed on the first connecting area of the connection point, and the assembling module 20 of the connecting device 100 is installed on the second connecting area of the connection point. "Multiple" means more than or equal to two, and the meaning of the word "multiple" in each embodiment is the same, and will not be repeated hereinafter.

[0041] When multiple connecting devices 100 are used to connect the first target object and the second target object, the connecting modules 10 of the connecting devices 100 can be installed on the corresponding first connecting areas of the first target object respectively, and the connecting modules 10 of the connecting devices 100 can be installed on the corresponding second connecting areas of the second target object respectively, wherein the operation of installing the connecting module 10 on the first target object and the operation of installing the assembling module 20 on the second target object can be carried out simultaneously in different workstations respectively, so as to improve the production efficiency.

[0042] Subsequently, when the connecting assembly 2 and the assembling module 20 are assembled, since the connecting module 10 is connected to the first target object and the connecting assembly 2 can remain on the first target object and the assembling module 20 can remain on the second target object, when the first target object and the second target object are aligned, one assembling tool can be used to drive the connecting assemblies 2 to move simultaneously, so that the connecting assemblies 2 can be matched with the corresponding assembling modules 20, thereby further improving the production efficiency.

[0043] In an actual scenario, the connecting device 100 can be applied to a vehicle to connect two components on the vehicle. For example, the connecting device 100 can be used to connect a vehicle body and a chassis of the vehicle, and one of the first target object and the second target object is the vehicle body and the other is the chassis. The vehicle body and the chassis usually have a plurality of connection points, and the connecting device 100 described above can be used to connect the vehicle body and the chassis at each connection point. Compared with the prior art, the connecting device 100 of the embodiment can improve the assembly efficiency of the vehicle body and the chassis.

[0044] In an embodiment, the connecting assembly 2 and the assembling module 20 are detachably connected, and before use, the connecting assembly 2 and the assembling module 20 can be matched together, so that the connecting device 100 is integrated, facilitating storage of the connecting device 100 and effectively preventing loss of components. When the connecting device 100 is used, the connecting assembly 2 and the assembling module 20 can be detached first, so that the assembling module 20 and the connecting module 10 are separated, and then the two are installed on the two target objects, respectively.

[0045] As shown in Figure 2 In an embodiment, the support assembly 1 has a first surface 11 and a second surface 12 arranged opposite to each other, and the support assembly 1 is further provided with a mounting hole 13 penetrating from the first surface 11 to the second surface 12; the connecting assembly 2 is arranged in the mounting hole 13 and can move along the axial direction of the mounting hole 13 to be matched with the assembling module 20; the mounting hole 13 is provided with a blocking structure 14 on the hole wall, and the connecting assembly 2 can abut against the blocking structure 14 when moving toward the first surface 11 side; and the connecting assembly 2 can abut against the limiting assembly 3 when moving toward the second surface 12 side. Wherein, “moving toward the first surface side” refers to moving in the direction from the second surface to the first surface; and “moving toward the second surface side” refers to moving in the direction from the first surface to the second surface.

[0046] That is, the hole wall of the mounting hole 13 can limit the connecting assembly 2 in the radial direction of the mounting hole 13, and the blocking structure 14 and the limiting assembly 3 can limit the connecting assembly 2 in the axial direction of the mounting hole 13.

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

[0048] Furthermore, when the connecting component 2 mates 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 mates with the assembly module 20 after passing through the mounting hole 13 from the first surface 11. This avoids interference from the hole wall of the mounting hole 13 when the assembly module 20 mates with the connecting component 2, and is more conducive to the mate 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 diameter of the first hole is smaller than the diameter of the second hole so that a stepped surface is formed between them. The stepped surface is the aforementioned blocking structure 14.

[0050] Additionally, the first hole can be used to guide the movement of the connecting assembly 2 along the axis of the mounting hole 13. After the connecting module 10 is assembled, the connecting assembly 2 has a portion located in the first hole and a portion located in the second hole.

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

[0052] The one of the first housing 15 and the second housing 16 that is connected to the assembly module 20 via the connecting component 2 is essentially connected to the second target object. Therefore, when the first target object moves relative to the second target object, the first elastic element 17 can buffer the relative movement between the first target object and the second target object. 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 ride comfort.

[0053] like Figure 2 As shown, the second housing 16 is fitted onto the first housing 15, which makes the support assembly 1 more integrated.

[0054] As shown in Figure 2 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, and 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 an embodiment, the first shell 15 has one end of the first surface 11 penetrating the second shell 16, and when the first shell 15 is connected with the second assembly module 20 through the connecting assembly 2, the one end of the first surface 11 can abut against the assembly module 20, and at this time, the first surface 11 is in contact with the assembly module 20.

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

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

[0058] As shown in Figure 2 In an embodiment, the outer surface of the second shell 16 is provided with a flange 162, which is used to connect with the first target object, wherein the flange 162 and the first target object can be connected together through a threaded connecting member or the like. Of course, the flange 162 and the first target object can also be connected together by welding or riveting or the like.

[0059] In one embodiment, the connecting component 2 is threadedly engaged with the assembly module 20. Specifically, in one feasible implementation, the connecting component 2 has a stud 21, and the assembly module 20 has a threaded hole. The stud 21 engages with the threaded hole to achieve the threaded engagement between the connecting component 2 and the assembly module 20. The stud 21 and the mounting hole 13 can be coaxially arranged. In another feasible implementation, to achieve the threaded engagement between the connecting component 2 and the assembly module 20, the connecting component 2 can also have a threaded hole, and the assembly module 20 can have a stud 21.

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

[0061] The "area opposite to the mounting hole 13" can refer to the portion of the base 31 whose orthographic projection on the first plane overlaps with the orthographic projection of the mounting hole 13 on the first plane. In other words, the orthographic projection of the area of ​​the base 31 opposite to the mounting hole 13 on the first plane overlaps with the orthographic projection of the mounting hole 13 on the first plane. Furthermore, the base 31 and the support assembly 1 can have a threaded fit. Specifically, the base 31 can have a threaded fit with the first housing 15, wherein the outer surface of the first housing 15 near the second surface 12 has an external thread, and the base 31 has an assembly hole, which is a threaded hole that is threaded into the end of the first housing 15 near the second surface 12. Additionally, the assembly hole is a blind hole, with its bottom wall opposite to the mounting hole 13. A clearance hole 311 is provided on the bottom surface of the assembly hole and penetrates through its bottom wall.

[0062] The assembly tool can apply force to the connecting component 2 at the clearance hole 311, causing it to move axially along the mounting hole 13 to achieve engagement with the assembly module 20. When the connecting component 2 can rotate about the axis of the mounting hole 13, the assembly tool also applies force to the connector from the clearance hole 311, allowing it to move both axially along and around the axis of the mounting hole 13. Furthermore, when the connecting component 2 moves along the direction from the first surface 11 to the second surface 12, it can abut against the base 31 to prevent it from exiting the mounting hole 13.

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

[0064] During assembly, the first limiting structure 22 and the second limiting structure 32 can be staggered, allowing the connecting component 2 and the assembly module 20 to be threaded together, thereby connecting the first target object and the second target object together. After assembly, the first limiting structure 22 and the second limiting structure 32 can be engaged to prevent the engagement between the connecting component 2 and the assembly module 20 from becoming loose, thus making the connection between the first target object and the second target object more secure.

[0065] Furthermore, the axis of the connecting component 2 can be parallel to the axis of the mounting hole 13; moreover, the connecting component 2 and the mounting hole 13 can be coaxially arranged. Additionally, the axis of the connecting component 2 is the same as 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 assembly 2, the connecting assembly 2 includes a first connecting member 23 and a second connecting member 24; the first connecting member 23 is threadedly engaged with the assembly module 20, and a first limiting structure 22 is disposed 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 assembly 2, so that the first connecting member 23 is threadedly engaged with the assembly module 20; that is, the assembly tool can apply torque to the second connecting member 24, thereby driving the first connecting member 23 to rotate through the second connecting member 24. In addition, the stud 21 of the connecting assembly 2 can be a part of the structure of the first connecting member 23. Furthermore, along the axis of the connecting assembly 2, the arrangement direction of the first connecting member 23 to the second connecting member 24 is the same as the arrangement direction of the first surface 11 to the second surface 12.

[0067] The second connecting piece 24 is movable along the axis of the connecting assembly 2 relative to the first connecting piece 23 to switch between the first position and the second position; wherein the first limiting structure 22 and the second limiting structure 32 are in the misaligned state when the second connecting piece 24 is in the first position; the first limiting structure 22 and the second limiting structure 32 are in the cooperating state when the second connecting piece 24 is in the second position; in addition, the first connecting piece 23 is provided with a first resisting structure, and the second connecting piece 24 is provided with a second resisting structure, the first resisting structure and the second resisting structure cooperate to prevent the first connecting piece 23 from rotating relative to the second connecting piece 24 when the second connecting piece 24 is in the first position and the second position.

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

[0069] As shown in Figure 2 In an implementable embodiment, the first connecting piece 23 is provided with a connecting column 25, the second connecting piece 24 is provided with a connecting hole 26, the connecting column 25 is located in the connecting hole 26; the first resisting structure is a flat position provided on the side surface of the connecting column 25, and the second resisting structure is a flat position provided on the inner surface of the connecting hole 26. In another implementable embodiment, the first connecting piece 23 is provided with a connecting hole 26, and the second connecting piece is provided with a connecting column 25, the connecting column 25 is located in the connecting hole 26; the first resisting structure is a flat position provided on the inner surface of the connecting hole 26, and the second resisting structure is a flat position provided on the side surface of the connecting column 25. Wherein, 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 abut against the bottom surface of the connecting hole 26, so that when the second connecting piece 24 moves relative to the first connecting piece 23 along the axis of the connecting assembly 2 to a certain position, the connecting column 25 can abut against the bottom surface of the connecting hole 26, thereby enabling the second connecting piece 24 to drive the first connecting piece 23 to move along the axis of the connecting assembly 2.

[0071] Furthermore, when the first connecting member 23 is provided with the connecting post 25, the connecting post 25 is connected with the threaded post 21 of the connecting assembly 2, wherein the threaded post 21 can be provided on the surface of the connecting post 25 which is away from the second connecting member 24, the threaded post 21 and the connecting post 25 are arranged along the direction from the first surface 11 to the second surface 12, the threaded post 21 and the connecting post 25 can be coaxially arranged, and the threaded post 21 and the connecting post 25 can be integrally arranged.

[0072] The first connecting member 23 further comprises a protrusion 27 (refer to Figure 2 ) which is arranged on the outer side of the connecting post 25 or the threaded post 21, and when the second connecting member 24 drives the first connecting member 23 to move towards the first surface 11 (i.e. the connecting assembly 2 moves towards the first surface 11), the protrusion 27 can be in contact with the resisting structure 14 (i.e. the protrusion 27 can be in contact with the stepped surface of the mounting hole), so as to prevent the first connecting member 23 from completely exiting the mounting hole 13 from the first surface 11. Furthermore, the end of the connecting post 25 which is away from the threaded post 21 extends into the connecting hole 26, and the end of the threaded post 21 which is away from the connecting post 25 is threadedly connected with the assembling module 20.

[0073] When the second connecting member 24 moves towards the second surface 12, the second connecting member 24 can be in contact with the base 31, so as to prevent the second connecting member 24 from completely exiting the mounting hole 13 from the second surface 12. Since the connecting post 25 can be in contact with the bottom surface of the connecting hole 26 when the first connecting member 23 moves towards the second surface 12, the second connecting member 24 can be prevented from completely exiting the mounting hole 13 from the second surface 12, and thus the first connecting member 23 can be prevented from completely exiting the mounting hole 13 from the second surface 12. In addition, the second connecting member 24 can have a portion which extends out of the mounting hole 13 from the avoiding hole 311 of the base 31, and this portion can pass through the base 31 to protrude from the surface of the base 31 which is away from the first surface 11.

[0074] As shown in Figure 2 , in an embodiment, along the axial direction of the connecting assembly 2, the second connecting member 24 comprises a first column 241 and a second column 242 which are coaxially arranged, wherein the diameter of the first column 241 is greater than the diameter of the second column 242, and a stepped surface is formed between the first column 241 and the second column 242. The first limiting structure 22 is arranged on the outer side of the first column 241, and the connecting hole 26 is arranged on the surface of the first column 241 which is away from the second column 242. When the second connecting member 24 is in the second position, the first column 241 can be in contact with the base 31, and the second column 242 can extend out of the mounting hole 13 from the avoiding hole 311. In addition, the second column 242 can be provided with a flat position for cooperating with the assembling tool, and further, the second column 242 can be a regular hexagonal prism, and in this case, the diameter of the second column 242 is its equivalent diameter. Furthermore, the first column 241 and the second column 242 can be coaxially arranged. The axial direction of the connecting assembly 2 is the axis of the connecting assembly 2.

[0075] As shown in Figure 2 In an embodiment, the connecting assembly 2 further comprises a second elastic member 28, the second elastic member 28 is connected with the second connecting member 24, initially, the second connecting member 24 is in the second position, when the 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 make the second elastic member 28 elastically deform; when the external force is removed, the second connecting member 24 can reset from the first position to the second position under the action of the deformation force of the second elastic member 28, so that the first limiting structure 22 and the second limiting structure 32 are more convenient to cooperate.

[0076] As shown in Figure 2 In an 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 stepped surface of the mounting hole 13 and the second connecting member 24, when the second connecting member 24 moves towards the first surface 11 side, the second elastic member 28 can be compressed to make the second elastic member 28 elastically deform.

[0077] As shown in Figure 2 In an embodiment, the connecting assembly 2 further comprises a gasket 29, the gasket 29 is sleeved on the first connecting member 23 and arranged between the second elastic member 28 and the second connecting assembly 2, so that the second connecting member 24 is more convenient to rotate.

[0078] As shown in Figure 2 In an embodiment, the limiting assembly 3 comprises a limiting member 33, and the second limiting structure 32 is arranged on the limiting member 33; the limiting member 33 is connected with 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, the first limiting structure 22 and the second limiting structure 32 are difficult to 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 swing around the axis of the connecting assembly 2, so that the relative position of the limiting member 33 and the second connecting member 24 in the circumferential direction of the mounting hole 13 can be adjusted conveniently, so that the first limiting structure 22 and the second limiting structure 32 are convenient to cooperate after the first connecting member 23 cooperates with the assembly module 20.

[0079] In addition, as shown in Figure 2 The limiting assembly 3 further comprises a third elastic member 34, and the limiting member 33 connects the supporting assembly 1 through the third elastic member 34; when the limiting member 33 swings around the axis of the connecting assembly 2, the third elastic member 34 can elastically deform.

[0080] In addition, when the mounting hole 13 is arranged on the support assembly 1, the limiting assembly 3 and the third elastic member 34 are arranged in the mounting hole 13. Moreover, when the limiting assembly 3 further has the base 31, the limiting member 33 is arranged in the mounting hole 13 and can contact the base 31 so as to be supported by the base 31.

[0081] As shown in Figure 3 and Figure 4 In an embodiment, the first limiting structure 22 includes a plurality of first engaging teeth 221 arranged on the side surface of the second connecting member 24, and each first engaging tooth 221 is uniformly 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 engaging teeth 321 arranged on the inner surface of the limiting ring, and each second engaging tooth 321 is uniformly arranged around the axis of the limiting ring. When the second connecting member 24 is located at the second position, each first engaging tooth 221 is located between two adjacent second engaging teeth 321, and two adjacent second engaging teeth 321 can accommodate one first engaging tooth 221. In this way, the first limiting structure 22 and the second limiting structure 32 are more conducive to cooperation. The axis of the second connecting member 24 is the axis of the connecting assembly 2.

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

[0083] As shown in Figure 2As shown, in an embodiment, the first limiting structure, the second limiting structure and the limiting ring are all arranged in the mounting hole 13; when the second connecting piece 24 is located at the first position, the first limiting structure is located at the side of the second limiting structure which is away from the second surface 12; the first engaging tooth 221 has a first guide surface, when the second connecting piece 24 is located at the second position, the first guide surface is adjacent to the second engaging tooth 321, the first guide surface extends from the end surface of the first engaging tooth 221 which is 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 engaging tooth 321 which is adjacent to it. In this way, it is more convenient for the first engaging tooth 221 to enter the accommodation gap. In addition, one first engaging tooth 221 has two first guide surfaces, in the circumferential direction of the mounting hole 13, the two first guide surfaces of one first engaging tooth 221 are respectively located at the two sides of the first engaging tooth 221, when the first engaging tooth 221 is located in the accommodation gap, the two first guide surfaces are respectively adjacent to the two second engaging teeth 321 on the two sides of the accommodation gap (the two second engaging teeth 321 form the accommodation gap between them), specifically, define the two first guide surfaces as guide surface a and guide surface b, when the first engaging tooth 221 is located in the accommodation gap, define the two second engaging teeth 321 on the two sides of the accommodation gap as engaging tooth a and engaging tooth b, wherein the guide surface a is adjacent to the engaging tooth a, and the guide surface b is adjacent to the engaging tooth b.

[0084] As shown, Figure 5 the second engaging tooth 321 has a second guide surface 322, when the second connecting piece 24 is located at the second position, the second guide surface 322 is adjacent to the second engaging tooth 321, the second guide surface 322 extends from the end surface of the second engaging tooth 321 which is 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 engaging tooth 221 which is adjacent to it. In this way, it is more convenient for the first engaging tooth 221 to enter the accommodation gap. In addition, one second engaging 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 engaging tooth 321 are respectively located at the two sides of the second engaging tooth 321.

[0085] As shown, Figure 1 and Figure 2As shown, in one embodiment, the assembly module 20 includes a connecting plate 4 and an assembly 5; the connecting plate 4 is used to connect a second target object; the assembly 5 is mounted on the connecting plate 4 and is used to cooperate with the connecting component 2; one of the assembly 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 5 and the connecting component 2 passes through the assembly hole 51; at least one of the assembly 5 and the connecting component 2 can move radially relative to the connecting plate 4 in the assembly hole 51. This arrangement is more conducive to allowing the assembly 5 or the connecting component 2 to enter the assembly hole 51.

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

The connecting plate 4 has a window 42 that extends through the connecting plate 4 along the direction from the first surface 11 to the second surface 12, communicating with the positioning space 41 and facing the assembly hole 51. The connecting assembly 2 passes through the window 42 and enters the assembly hole 51. Furthermore, when the assembly 5 moves radially along the assembly hole 51 to its maximum position within the positioning space 41, the assembly hole 51 remains opposite to the window 42. In this configuration, only the assembly 5 can move radially relative to the connecting plate 4 within the assembly hole 51.

[0088] like Figure 2 As shown, the positioning space 41 can be a blind hole set on the surface of the connecting plate 4 away from the support component 1, and the window 42 is set on the bottom surface of the positioning space 41 and extends through to the surface of the connecting plate 4 near the support component 1.

[0089] In addition, the end of the connecting assembly 2 used for cooperating with the assembling member 5 (i.e. the end of the connecting assembly 2 away from the second surface 12) is provided with a first guide portion so as to guide the connecting assembly 2 into the assembling hole 51. Of course, the end of the assembling hole 51 close to the supporting assembly 1 can also be provided with a second guide portion so as to guide the connecting assembly 2 into the assembling hole 51. The first guide portion can be a tapered portion, and the first guide portion can be a part of the stud 21, which is the end of the stud 21 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 can 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.

At this time, the assembling member 5 is a bolt structure, and the connecting assembly is provided with a threaded hole.

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

[0094] In other embodiments, the second elastic member 28 can also be arranged between the second connecting member 24 and the base 31, and can stretch the second elastic member 28 when the second connecting member 24 moves towards the first surface 11, so as to make the second elastic member 28 elastically deform.

[0095] In other embodiments, the first housing 15 can also be arranged outside the second housing 16, and the two are connected together by the first elastic member.

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

[0099] Specifically, the connecting plate 4 can be mounted on the surface of the vehicle body close to the chassis (i.e., mounted on the lower surface of the vehicle body), at this time, 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 assembling 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 assembling part 5 in the assembling hole 51, so that after the connecting plate 4 is connected to the vehicle body, the assembling part 5 can move along the radial direction of the assembling hole 51.
